The abnormality is detected, especially, in a pulverizing process for pulverizing grain. Thus, the automatic bread maker safely makes bread.

Description

  The present invention relates to an automatic bread maker mainly used in general households.

  A commercially available automatic bread maker for home use generally has a mechanism for producing bread by directly using a bread container for storing bread ingredients as a baking mold. In such an automatic bread maker, first, a bread container in which bread ingredients are placed is placed in a baking chamber in the main body. And the bread raw material in a bread container is kneaded into bread dough with the kneading blade provided in a bread container (kneading process). Thereafter, a fermentation process for fermenting the kneaded bread dough is performed, and the bread container is used as a baking mold to bake the bread (baking process).

  When bread is manufactured using such an automatic bread maker, so far, flour (wheat flour, rice flour, etc.) or flour such as wheat or rice is used as the raw material for bread. It was necessary to have a mixed powder in which various auxiliary materials were mixed. However, in general households, as represented by rice grains, grains are sometimes held in the form of grains instead of in the form of flour. For this reason, it is very convenient if the automatic bread maker is configured to produce bread directly from grain. With this in mind, the present applicants have developed a bread production method for producing bread using cereal grains as a starting material (see Patent Document 1).

  In this bread manufacturing method, first, cereal grains and a liquid are mixed, and a pulverizing blade is rotated in the mixture to pulverize the cereal grains (grinding step). And the bread raw material containing the paste-form ground powder obtained through the grinding process is kneaded into bread dough using a kneading blade (kneading process). Thereafter, a fermentation process for fermenting the kneaded bread dough is performed, followed by a baking process for baking the bread.

  Incidentally, a commercially available automatic bread maker for home use may be provided with means for detecting an abnormality during operation. For example, Patent Documents 2 to 4 propose an automatic bread maker provided with a detecting means for detecting a temperature abnormality in the baking chamber or detecting a power failure.

FIG. 2 is a schematic perspective view showing the configuration of the lid of the automatic bread maker according to this embodiment. As shown in FIG. 1, an operation unit 20 is provided on a part of the upper surface of a main body 10 (the outer shell of which is formed of, for example, metal or synthetic resin) of an automatic bread maker 1 provided in a substantially rectangular parallelepiped shape. It has been. The operation unit 20 includes an operation key group, and an output unit 21 that displays time, contents set by the operation key group, abnormality of the automatic bread maker, and the like. The operation key group includes, for example, a start key, a cancel key, a timer key, a reservation key, a bread manufacturing course (a manufacturing process for manufacturing bread using rice grains as a starting material, and manufacturing bread using rice flour as a starting material) And a selection key for selecting a manufacturing process, a manufacturing process for manufacturing bread using wheat flour as a starting material, and the like. The output unit 21 includes, for example, a liquid crystal display panel, a light emitting element, a speaker, and the like, and notifies the user by outputting sound and light (including images). In the present embodiment, the output unit 21 serves as an abnormality notifying unit that notifies an abnormality and an end time notifying unit that notifies an end time.

  Inside the main body 10, a firing chamber 30 is provided, which will be described later in detail. The baking chamber 30 is a box-shaped chamber having a substantially rectangular shape, which includes a bottom wall 30a made of, for example, sheet metal and four side walls 30b (see also FIG. 5), and an upper surface thereof is open. The firing chamber 30 can be opened and closed by a lid 40 (an example of the lid portion of the present invention) provided on the upper portion of the main body 10, and the firing chamber is shielded by closing the lid 40. Further, at least one side wall 30b of the baking chamber 30 is provided with guide portions 32a and 32b and a movable portion 33 (see also FIG. 5 and details will be described later). The lid 40 is attached to the back side of the main body 10 with a hinge shaft (not shown), and the firing chamber 30 can be opened and closed by rotating about the hinge shaft as a fulcrum. FIG. 1 shows a state where the lid 40 is opened.

  The lid 40 is provided with a viewing window 41 made of, for example, heat-resistant glass so that the inside of the baking chamber 30 can be seen. Moreover, the bread raw material storage container 19 is detachably attached to the lid 40. This bread ingredient storage container 19 makes it possible to automatically feed some bread ingredients during the bread production process. 1 and 2 show a state in which the bread ingredient storage container 19 is attached to the lid 40, and more specifically shows a state in which the container lid of the bread ingredient storage container 19 is opened.

  As shown in FIG. 2, a frame member 42 (for example, formed of an aluminum alloy die-cast product) is accommodated in the lid 40 of the automatic bread maker 1, and the frame member 42 is formed from the back side of the lid 40. It is supported by an inner cover 43 (for example, made of sheet metal). In the frame member 42, a recessed space 45 formed by a dome-shaped wall 42b is formed in a portion near the back surface of the main body 10 when the lid 40 is closed. The recessed space 45 is a holding portion that holds the bread ingredient storage container 19. The portion of the frame member 42 that is closer to the front surface of the main body 10 when the lid 40 is in the closed state has a substantially rectangular shape surrounded by the wall 42a (assuming the lid 40 is viewed from the back side). Through-holes 44 are provided. The wall portion 42 a abuts on the observation window 41 disposed on the upper surface side of the lid 40 and supports the observation window 41.

  Further, the lid 40 has an inclined structure in which substantially the entire upper surface of the lid 40 becomes higher from the front side to the back side of the main body 10 in a closed state. For this purpose, in a state where the lid 40 is closed, the first bread container 80 (see FIG. 5 described later) or the second bread stored in the baking chamber 30 from the observation window 41 arranged near the front surface of the main body 10. The state in the container 110 (see FIG. 9 described later) is easy to observe. Further, in the state in which the lid 40 is closed, the bread ingredient storage container 19 attached to the back side of the main body 10 is arranged in a portion where the thickness of the lid 40 is thick. You can earn volume.

  A magnetic sensor 17 is provided in the vicinity of the side of the main body 10 near the upper rear surface on the side where the operation unit 20 is provided and facing the lid 40. Specifically, the magnetic sensor 17 is fixedly disposed inside the main body 10 and cannot be seen from the outside. Therefore, in FIG. 1, the magnetic sensor 17 is indicated by a broken line.

  In addition, a permanent magnet 18 is fixedly disposed on the lid 40 so as to face the magnetic sensor 17 disposed on the main body 10 when the lid 40 is closed. For example, the permanent magnet 18 may have a configuration in which a concave portion is provided on the outer surface of the lid 40 and is fixedly arranged in the concave portion, or may be fixedly arranged inside the lid 40. In the present embodiment, since the permanent magnet 18 is not visible when the lid 40 is viewed from above, the permanent magnet 18 is indicated by a broken line in FIG.

  In order to make the lid 40 open, the lid 40 is rotated from the closed state (here, assuming that the lower surface of the lid 40 and the main body 10 are in contact) to the back side. Then, the permanent magnet 18 moves in a direction away from the magnetic sensor 17 (see FIG. 1). For this reason, when the lid 40 is opened, the magnitude of the magnetic force detected by the magnetic sensor 17 changes. That is, the magnetic sensor 17 can detect the open / closed state of the lid 40.

  In the automatic bread maker 1 of this embodiment, the magnetic sensor 17 is configured to detect the opening / closing of the lid 40 in pairs with the permanent magnet 18. What is necessary is just to determine suitably the magnetic force of the permanent magnet 18 so that the magnetic sensor 17 can detect the change of the magnetic force accompanying the opening / closing operation | movement of the lid | cover 40 reliably. In the present embodiment, the magnetic sensor 17 and the permanent magnet 18 are positioned closer to the back surface of the automatic bread maker 1 when the lid 40 is closed. However, the present invention is not limited to this configuration. For example, in a state where the lid 40 is closed, the magnetic sensor 17 and the permanent magnet 18 may be positioned closer to the front (front side) of the automatic bread maker 1.

  As described above, in the present embodiment, the magnetic sensor 17 serves as a lid opening / closing detection unit that detects opening / closing of the lid 40. Specifically, the state where the magnetic sensor 17 detects the magnetic force of the permanent magnet 18 indicates that the lid 40 is closed, and the state where the magnetic sensor 17 does not detect the magnetic force of the permanent magnet 18 indicates that the lid 40 is opened. Indicates that

  In the automatic bread maker 1 of this embodiment, an automatic charging solenoid 16 (see FIG. 15 described later) is provided in the main body 10 on the lower side of the operation unit 20. When the solenoid 16 is driven, the plunger protrudes from the opening 10b provided in the main body wall surface 10a adjacent to the lid 40. Then, the protruding plunger presses the opening switch 46 provided on the side wall 40a of the lid 40, whereby the bread raw material storage container 19 is opened (the state shown in FIGS. 1 and 2). The bread ingredient storage container 19 stores bread ingredients (for example, powder bread ingredients such as gluten and dry yeast), and the bread ingredient storage container 19 is opened so that the bread ingredients are accommodated in the baking chamber 30. The first bread container 80 (see FIG. 5 described later) or the second bread container 110 (refer to FIG. 9 described later) is charged.

  The inside of the lid 40 (for example, the frame member 42 and the like) and the bread raw material storage container 19 are preferably light and excellent in durability when the surface is anodized with aluminum as the base material. The surface treatment may be performed by other methods (for example, silicon coating or fluorine coating).

  FIG. 3 is a schematic diagram for explaining a configuration inside the main body of the automatic bread maker according to the present embodiment. FIG. 3 assumes a case where the automatic bread maker 1 is viewed from above, and the lower side of the figure is the front side of the automatic bread maker 1 and the upper side of the figure is the back side. As shown in FIG. 3, in the automatic bread maker 1, a low-speed / high-torque type kneading motor 50 used in the kneading process is fixedly arranged on the right side of the baking chamber 30, and the grinding process is performed behind the baking chamber 30. The high-speed rotation type crushing motor 60 used in the above is fixedly arranged. The kneading motor 50 and the crushing motor 60 are both shafts.

  A first pulley 52 is fixed to an output shaft 51 protruding from the upper surface of the kneading motor 50. The first pulley 52 is connected by a first belt 53 to a second pulley 55 having a diameter larger than that of the first pulley 52 and fixed to the upper side of the first rotating shaft 54. Has been. A second rotating shaft 57 is provided on the lower side of the first rotating shaft 54 so that the center of rotation is substantially the same as the first rotating shaft 54 (see also FIG. 4 described later). The first rotating shaft 54 and the second rotating shaft 57 are rotatably supported inside the main body 10. Further, a clutch 56 that performs power transmission and power interruption is provided between the first rotating shaft 54 and the second rotating shaft 57 (see also FIG. 4 described later). The configuration of the clutch 56 will be described later.

  A third pulley 58 is fixed to the lower side of the second rotating shaft 57 (see also FIG. 4 described later). The third pulley 58 is provided on the lower side of the firing chamber 30 by the second belt 59 and is fixed to the driving shaft 11 and has a first driving shaft pulley 12 (having substantially the same diameter as the third pulley 58). (See FIG. 4 to be described later). The kneading motor 50 itself is a low speed / high torque type, and the rotation of the first pulley 52 is decelerated and rotated by the second pulley 55 (for example, decelerated to 1/5 speed). For this reason, when the kneading motor 50 is driven in a state where the clutch 56 transmits power, the driving shaft 11 rotates at a low speed (for example, about 180 rpm) and a high torque.

  The first pulley 52, the first belt 53, the first rotating shaft 54, the second pulley 55, the clutch 56, the second rotating shaft 57, the third pulley 58, the second belt 59, and Hereinafter, the power transmission unit configured by the first driving shaft pulley 12 may be expressed as a first power transmission unit PT1.

  A fourth pulley 62 is fixed to the output shaft 61 protruding from the lower surface of the grinding motor 60. The fourth pulley 62 is fixed by a third belt 63 below the second driving shaft pulley 13 (below the first driving shaft pulley 12) fixed to the driving shaft 11; 4). The second driving shaft pulley 13 has substantially the same diameter as the fourth pulley 62. A grinding motor 60 that can rotate at high speed is selected. Since the rotation of the fourth pulley 62 is maintained at substantially the same speed in the second driving shaft pulley 13, the driving shaft 11 rotates at a high speed (for example, 7000 to 8000 rpm) by the high speed rotation of the grinding motor 60. Do.

  In the following, the power transmission unit configured by the fourth pulley 62, the third belt 63, and the second driving shaft pulley 13 may be expressed as a second power transmission unit PT2. . The second power transmission unit PT2 has a configuration that does not have a clutch, and connects the output shaft 61 of the crushing motor 60 and the driving shaft 11 so that power can be transmitted constantly.

  FIG. 4 is a diagram for explaining a clutch included in the first power transmission unit provided in the automatic bread maker of the present embodiment. FIG. 4 is a diagram assuming the case of viewing along the direction of arrow X in FIG. 3. 4A shows a state in which the clutch 56 performs power cut-off, and FIG. 4B shows a state in which the clutch 56 performs power transmission.

  As shown in FIG. 4, the clutch 56 includes a first clutch member 561 and a second clutch member 562. And when the nail | claw 561a provided in the 1st clutch member 561 and the nail | claw 562a provided in the 2nd clutch member 562 mesh (state of FIG.4 (b)), the clutch 56 transmits motive power. In addition, when the two claws 561a and 562a are not engaged with each other (the state shown in FIG. 4A), the clutch 56 cuts off the power. That is, the clutch 56 is a meshing clutch.

  In the present embodiment, each of the two clutch members 561 and 562 has a circumferential direction (when the first clutch member 561 is seen in plan view from below, or the second clutch member 562 is seen in plan view from above. Assuming the case), six claws 561a and 562a arranged at almost equal intervals are provided, but the number of the claws may be appropriately changed. Moreover, what is necessary is just to select a preferable shape suitably for the shape of nail | claw 561a and 562a.

  The first clutch member 561 is attached to the first rotating shaft 54 so as to be slidable in the axial direction (vertical direction in FIG. 4) and not to be relatively rotatable, after taking measures against slipping off. Yes. A spring 71 is loosely fitted on the upper side of the first clutch member 561 of the first rotating shaft 54. The spring 71 is disposed so as to be sandwiched between a stopper portion 54a provided on the first rotating shaft 54 and the first clutch member 561, and biases the first clutch member 561 downward. ing. On the other hand, the second clutch member 562 is fixed to the upper end of the second rotating shaft 57.

  Switching between the power transmission state and the power cut-off state in the clutch 56 is performed using an arm portion 72 that can be selectively arranged at the lower position and the upper position. A part of the arm portion 72 is disposed below the first clutch member 561 and can come into contact with the outer peripheral side of the first clutch member 561.

  The arm unit 72 is driven using a clutch solenoid 73. The clutch solenoid 73 includes a permanent magnet 73a and is a so-called self-holding solenoid. The plunger 73 b of the clutch solenoid 73 is fixed to the plunger fixing attachment portion 72 a of the arm portion 72. For this reason, the arm part 72 moves according to the movement of the plunger 73b in which the amount of protrusion from the housing 73c varies due to the application of voltage.

  When the arm portion 72 moves from the lower position (the state shown in FIG. 4B) to the upper position (the state shown in FIG. 4A), the first clutch member 561 is pushed by the arm portion 72 and attached with the spring 71. Moves up against the forces. When the arm portion 72 is in the upper position, the first clutch member 561 and the second clutch member 562 do not mesh with each other. That is, when the arm portion 72 is in the upper position, the clutch 56 performs power interruption.

  On the other hand, when the arm portion 72 moves from the upper position to the lower position, the first clutch member 561 moves downward while being pushed by the urging force of the spring 71. When the arm portion 72 is in the lower position, the first clutch member 561 and the second clutch member 562 are engaged with each other. That is, when the arm portion 72 is in the lower position, the clutch 56 transmits power.

  When the crushing motor 60 is driven, if the clutch 56 is in a state of transmitting power (the state shown in FIG. 4B), the rotational power for rotating the driving shaft 11 at high speed is transmitted to the output shaft 51 of the kneading motor 50. (See FIG. 3). In this case, if the crushing motor 60 is rotated at, for example, 8000 rpm, the output shaft 51 of the kneading motor 50 is rotated at 40000 rpm depending on the radius ratio (for example, 1: 5) between the first pulley 52 and the second pulley 55. The power to make it necessary. As a result, a very large load is applied to the pulverization motor 60, and the pulverization motor 60 may be damaged. For this reason, when driving the grinding motor 60, it is necessary to prevent the rotational power for rotating the driving shaft 11 from being transmitted to the output shaft 51 of the kneading motor 50. Thus, as described above, the automatic bread maker 1 includes the clutch 56 that performs power transmission and power interruption in the first power transmission unit PT1.

  As described above, in the automatic bread maker 1, the second power transmission unit PT2 is not provided with a clutch. This is due to the following reason. That is, even if the kneading motor 50 is driven, the driving shaft 11 is only rotated at a low speed (for example, 180 rpm). For this reason, even if the rotational power for rotating the driving shaft 11 is transmitted to the output shaft of the crushing motor 60, a large load is not applied to the kneading motor 50. And the manufacturing cost of the automatic bread maker 1 is suppressed by adopting the structure in which the clutch is not provided in the second power transmission part PT2 in this way. However, it goes without saying that a configuration in which a clutch is provided in the second power transmission unit PT2 may be adopted.

  FIG. 5 is a diagram schematically showing the configuration of the baking chamber in which the first bread container is accommodated and its surroundings in the automatic bread maker of the present embodiment. FIG. 5 assumes a configuration when the automatic bread maker 1 is viewed from the front side, and the configurations of the baking chamber 30 and the first bread container 80 are generally shown in cross-sectional views. Note that the first bread container 80 used as a bread baking mold as well as the bread raw material is charged into and out of the baking chamber 30.

  As shown in FIG. 5, a sheathed heater 31 is disposed inside the baking chamber 30 so as to surround the first bread container 80 accommodated in the baking chamber 30. By using the sheathed heater 31, it is possible to heat the bread ingredients (including the dough) in the first bread container 80.

  Referring to FIG. 5, a bread container support portion 14 (for example, made of an aluminum alloy die-cast product) that supports the first bread container 80 is fixed at a position that is substantially at the center of the bottom wall 30 a of the baking chamber 30. Has been. The bread container support portion 14 is formed so as to be recessed from the bottom wall 30a of the baking chamber 30, and the shape of the recess is substantially circular when viewed from above. At the center of the bread container support portion 14, the above-described driving shaft 11 is supported so as to be substantially perpendicular to the bottom wall 30a. A main body side connecting portion 11 a is fixed to the upper end of the driving shaft 11.

  The first bread container 80 is, for example, an aluminum alloy die-cast product (others may be made of sheet metal or the like), has a bucket-like shape, and is provided on the side edge of the opening. A hand handle (not shown) is attached to 80a. The horizontal section of the first bread container 80 is a rectangle with rounded corners. In addition, a concave portion 81 having a substantially circular shape in plan view is formed on the bottom of the first bread container 80 so as to accommodate a part of a blade unit 90 described later in detail.

  At the center of the bottom of the first bread container 80, a blade rotation shaft 82 extending in the vertical direction is rotatably supported in a state where a countermeasure against sealing is taken. A container-side connection portion 82a is fixed to the lower end of the blade rotation shaft 82 (projecting outward from the bottom of the first bread container 80).

  A cylindrical pedestal 83 is provided on the bottom outer surface side of the first bread container 80 so as to surround the blade rotation shaft 82. The first bread container 80 is accommodated in the baking chamber 30 in a state where the pedestal 83 is received by the bread container support portion 14. The pedestal 83 may be formed separately from the first bread container 80 or may be formed integrally with the first bread container 80.

  When the pedestal 83 of the first bread container 80 is received by the bread container support portion 14, the first bread container 80 is accommodated in the accommodation position (position shown in FIG. 5) in the baking chamber 30. The connection between the container side connecting portion 82a provided at the lower end of the rotating shaft 82 and the main body side connecting portion 11a fixed to the upper end of the driving shaft 11 is obtained. As a result, the blade rotation shaft 82 can transmit the rotational power from the driving shaft 11. That is, the main body side connecting portion 11a and the container side connecting portion 82a constitute a coupling.

  Also, as shown in FIG. 5, at least one side wall 80b (in this example, two opposing side walls 80b) of the first bread container 80 is provided with projecting portions 84a and 84b projecting outward. On the other hand, at least one side wall 30b (two opposing side walls 30b in this example) of the baking chamber 30 is provided with guide portions 32a and 32b protruding inward. The configuration of the protruding portions 84a and 84b and the configuration of the guide portions 32a and 32b are the same.

  When the 1st bread container 80 is accommodated in the accommodation position in the baking chamber 30, each of protrusion part 84a, 84b and guide part 32a, 32b fits (it mentions later for the detail of a structure). That is, the user inserts the bottom wall of the first bread container 80 toward the bottom wall 30a of the baking chamber 30 so that the projecting portions 84a and 84b and the guide portions 32a and 32b are fitted (lower side in the figure). The first bread container 80 can be easily accommodated in the accommodating position in the baking chamber 30 by being moved in the direction). In addition, in FIG. 5, although the case where the protrusion part 84a, the guide part 32a, the protrusion part 84b, and the guide part 32b fit is illustrated, the protrusion part 84b and the guide part 32a, the protrusion part 84a, and the guide part 32b are respectively shown. There may be a case where the left and right sides of the first bread container 80 shown in FIG. 5 are reversed. Also in this case, the first bread container 80 can be accommodated in the accommodating position in the baking chamber 30.

  In addition, at least one of the side walls 30b provided with the guide portions 32a and 32b of the baking chamber 30 (in this example, the side wall 30b provided with the guide portions 32a) is provided with a movable portion 33 protruding inward. The movable portion 33 is movable in a direction substantially equal to the depth direction of the baking chamber 30 (the insertion direction and the removal direction of the first bread container 80) (details of the structure will be described later). When the first bread container 80 is inserted into the baking chamber 30 and reaches the storage position, the protruding portion 84a (which may be the protruding portion 84b) pushes the movable portion 33 down to the bottom side of the baking chamber 30. Although details will be described later, the automatic bread maker 1 of the present embodiment detects whether or not the first bread container 80 is accommodated in the accommodating position in the baking chamber 30 by detecting the depression of the movable portion 33. Is detected.

  In addition, a blade unit 90 is detachably attached to a portion of the blade rotating shaft 82 that protrudes into the first bread container 80 from above. The configuration of the blade unit 90 will be described with reference to FIGS.

  FIG. 6 is a schematic perspective view showing the configuration of the blade unit mounted on the first bread container in the automatic bread maker of the present embodiment. FIG. 7 is a schematic exploded perspective view showing the configuration of the blade unit mounted on the first bread container in the automatic bread maker of the present embodiment. FIG. 8 is a diagram showing a configuration of a blade unit mounted on the first bread container in the automatic bread maker of the present embodiment, FIG. 8A is a schematic side view, and FIG. 8B is FIG. It is sectional drawing in the AA position of a).

  The blade unit 90 is roughly attached to the unit shaft 91, the pulverizing blade 92 attached to the unit shaft 91 so as not to rotate relative to the unit shaft 91, and to the unit shaft 91 so as to be relatively rotatable and covering the pulverizing blade 92 from above. A configuration comprising: a dome-shaped cover 93 that is substantially circular in plan view; a kneading blade 101 that is attached to the dome-shaped cover 93 so as to be relatively rotatable; and a guard 106 that is attached to the dome-shaped cover 93 and covers the grinding blade 92 from below. (For example, refer to FIGS. 6 to 8).

  In the state where the blade unit 90 is attached to the blade rotation shaft 82, the crushing blade 92 is positioned slightly above the bottom surface of the concave portion 81 of the first bread container 80. Further, almost the entire grinding blade 92 and dome-shaped cover 93 are accommodated in the recess 81 (see, for example, FIG. 5).

  The unit shaft 91 is a substantially cylindrical member formed of a metal such as a stainless steel plate, for example, and has an opening at one end (lower end), and the inside is hollow. That is, the unit shaft 91 has a configuration in which an insertion hole 91c is formed so that the blade rotation shaft 82 can be inserted from the lower end (see, for example, FIG. 8B).

  Further, a pair of cutout portions 91a are formed on the lower side (opening side) of the side wall of the unit shaft 91 so as to be symmetrically arranged with respect to the rotation center of the unit shaft 91 (see, for example, FIG. 7). FIG. 7 shows only one of the pair of cutout portions 91a). The shape of the notch 91a is substantially rectangular in a side view, and in detail, one end (upper end) is rounded. The notch 91a is provided to engage the pin 821 (see FIG. 8B) penetrating the blade rotation shaft 82 horizontally. When the pin 821 of the blade rotating shaft 82 and the notch 91a are engaged, the unit shaft 91 is attached to the blade rotating shaft 82 so as not to be relatively rotatable.

  As shown in FIG. 8B, the inner side of the unit shaft 91 is engaged with a convex portion 82b provided at the center of the upper end surface (substantially circular) of the blade rotation shaft 82 (shown by a broken line). A recess 91b is formed at the center of the upper surface of the substrate. Accordingly, the blade unit 90 can be easily attached to the blade rotation shaft 82 in a state where the centers of the unit shaft 91 and the blade rotation shaft 82 are aligned. For this reason, when the blade rotating shaft 82 is rotated, occurrence of unnecessary rattling is suppressed. In the present embodiment, the convex portion 82b is provided on the blade rotating shaft 82 side and the concave portion 91b is provided on the unit shaft 91 side, but conversely, the concave portion is provided on the blade rotating shaft 82 side and the unit shaft 91 side is provided. A configuration in which a convex portion is provided may be employed.

  The pulverizing blade 92 for pulverizing grains is formed by processing a stainless steel plate, for example. For example, as illustrated in FIG. 7, the pulverizing blade 92 includes a first cutting portion 921, a second cutting portion 922, and a connecting portion 923 that connects the first cutting portion 921 and the second cutting portion 922. And comprising. An opening 923 a having a substantially rectangular shape (stadium shape) in plan view is formed at the center of the connecting portion 923. The grinding blade 92 is attached to the unit shaft 91 such that the lower side of the unit shaft 91 is fitted into the opening 923a.

  A flat surface is formed on the lower side of the unit shaft 91 by shaving a part of the side surface (near the position where the notch 91a is provided). Thereby, when the unit shaft 91 is viewed from below, the lower side of the unit shaft 91 has substantially the same shape (substantially rectangular shape) as the opening 923a provided in the connecting portion 923. The area when the lower side of the unit shaft 91 is viewed in plan is slightly smaller than the opening 923a. Since such a shape is adopted, the grinding blade 92 is attached to the unit shaft 91 so as not to be relatively rotatable. Since the stopper member 94 for preventing the retaining member 94 is fitted into the unit shaft 91 on the lower side of the pulverizing blade 92, the pulverizing blade 92 does not fall off the unit shaft 91.

  The dome-shaped cover 93 disposed so as to surround and cover the crushing blade 92 is made of, for example, an aluminum alloy die-cast product, and a bearing 95 (in this embodiment, a rolling bearing is used on the inner surface side thereof. ) (See FIG. 8B) is formed. In other words, in order to form the accommodating portion 931, the dome-shaped cover 93 has a configuration in which a substantially cylindrical convex portion 93a is formed at the center when viewed from the outer surface. In addition, the opening is not formed in the convex part 93a, and the bearing 95 accommodated in the accommodating part 931 is in the state in which the side surface and the upper surface are enclosed by the wall surface of the accommodating part 931.

  The inner ring 95a is attached to the unit shaft 91 so as not to rotate relative to the bearing 95 with the retaining rings 96a and 96b arranged on the upper and lower sides (the unit shaft 91 is press-fitted into a through hole inside the inner ring 95a. ing). The bearing 95 is press-fitted into the housing portion 931 so that the outer wall of the outer ring 95b is fixed to the side wall of the housing portion 931. The dome-shaped cover 93 is attached to the unit shaft 91 so as to be rotatable relative to the bearing 95 (the inner ring 95a rotates relative to the outer ring 95b).

  In addition, the housing portion 931 of the dome-shaped cover 93 is made of, for example, a silicon-based material so that foreign matter (for example, liquid used when pulverizing grain grains or paste-like material obtained by pulverization) does not enter the bearing 95 from the outside. Alternatively, a seal material 97 formed of a fluorine-based material and a metal seal cover 98 that holds the seal material 97 are press-fitted from the lower side of the bearing 95. The seal cover 98 is fixed to the dome-shaped cover 93 with a rivet 99 so that the fixing to the dome-shaped cover 93 is ensured. Although fixing with the rivet 99 may not be performed, it is preferable to configure as in the present embodiment in order to obtain reliable fixing. The sealing material 97 and the sealing cover 98 function as sealing means. The seal cover 98 is preferably coated with fluorine or the like. In particular, it is preferable to use a silver paint because the coating is difficult to peel off and even if it is peeled off, it is difficult to stand out.

  On the outer surface of the dome-shaped cover 93, a kneading blade 101 (for example, aluminum) in a planar shape is formed by a support shaft 100 (see FIG. 7) disposed so as to extend in a vertical direction at a location adjacent to the convex portion 93 a. (Made of die-cast alloy product) is attached. The kneading blade 101 is attached to the support shaft 100 so as not to be relatively rotatable, and moves together with the support shaft 100 attached to the dome-shaped cover 93 so as to be relatively rotatable. In other words, the kneading blade 101 is attached to the dome-shaped cover 93 so as to be relatively rotatable.

  As shown in FIGS. 6 to 8, a cushioning material 107 is provided on one surface near the tip of the kneading blade 101 (assuming a portion that draws the largest circle when the kneading blade 101 is rotated about the support shaft 100). It is attached. The buffer material 107 is provided so as to protrude from the tip of the kneading blade 101 (see, for example, FIG. 8A).

  The buffer material 107 is fixed in a state where the buffer material 107 is sandwiched between one surface of the kneading blade 101 and the fixing plate 108 and obtained by caulking the rivet 109 inserted from the other surface side of the kneading blade 101. ing. In the present embodiment, the number of rivets 109 is two, but it goes without saying that the number is not limited.

  The cushioning material 107 is disposed so as not to come into direct contact with the first bread container 80 (inner wall thereof) when the kneading blade 101 is in an open posture, which will be described in detail later. If the kneading blade 101 and the first bread container 80 are in direct contact with each other, damage may occur due to interference between them, and the buffer material 107 is provided to prevent such damage. Yes.

  In the automatic bread maker 1 of this embodiment, the surfaces of the first bread container 80 and the kneading blade 101 are coated with fluorine. For this reason, it can be said that the buffer material 107 of the present embodiment is provided so that the fluorine coating is not peeled off by contact between the kneading blade 101 and the first bread container 80. From this point, the material constituting the cushioning material 107 is preferably a material softer than the coating material so as not to peel off the fluorine coating. For example, silicone rubber or TPE (Thermoplastic Elastomers) is used. . The buffer material 107 also functions as a soundproofing measure, which will be described later. In the following description, the buffer material 107 may be regarded as a part of the kneading blade 101.

  Further, in the present embodiment, a complementary kneading blade 102 (for example, made of an aluminum alloy die cast product) is fixedly disposed on the outer surface of the dome-shaped cover 93 so as to be aligned with the kneading blade 101. The complementary kneading blade 102 is not necessarily provided, but is preferably provided in order to increase the kneading efficiency in the kneading process of kneading the bread dough.

  FIG. 9 is a partial cross-sectional view illustrating a schematic configuration of the automatic bread maker according to the present embodiment, and is a diagram illustrating a configuration when a second bread container is used. FIG. 9 assumes a case where the automatic bread maker is viewed from the front side. In addition, the description of the same configuration as that in the case where the first bread container 80 is used (see FIG. 5) will be omitted if there is no need for description.

  The second bread container 110 (for example, made of sheet metal) has a bucket-like shape like the first bread container 80, and a handle (not shown) is provided for the hook 110a provided on the side edge of the opening. Is attached. The second bread container 110 also has a horizontal section that is a rectangle with rounded corners. However, a recess 81 like the first bread container 80 is not formed at the bottom of the second bread container 110. This is related to the fact that when the second bread container 110 is used, there is no crushing step and it is not necessary to attach the crushing blade 92. In addition, the second bread container 110 does not need to be provided with the recess 81, and therefore has a lower height than the first bread container 80. Further, unlike the first bread container 80, the second bread container 110 is not provided with the above-described protrusions 84a and 84b (see FIG. 5) on the side wall 110b. Furthermore, when the 2nd bread container 110 is accommodated in the accommodation position (position shown in FIG. 9) in the baking chamber 30, the 2nd bread container 110 (especially collar part 110a) and guide part 32a, 32b contact. It is configured not to.

  At the center of the bottom of the second bread container 110, a second blade rotating shaft 111 extending in the vertical direction is supported in a state where measures against sealing are taken. A container-side coupling member 111a is fixed to the lower end of the second blade rotating shaft 111 (external to the second bread container 110). Further, a cylindrical pedestal 112 is provided on the outer bottom surface of the second bread container 110, and the second bread container 110 is in a baking chamber in a state where the pedestal 112 is received by the bread container support part 14. 30 is arranged inside.

  In addition, the coupling | bonding method of this base 112 and the bread container support part 14 is the same as the coupling | bonding method of the base 83 of the 1st bread container 80, and the bread container support part 14. FIG. Further, the coupling between the pedestal 112 and the bread container support portion 14 connects the container side coupling member 111 a provided on the second blade rotation shaft 111 and the driving shaft side coupling member 11 a fixed to the driving shaft 11. (Coupling) is also achieved. By this coupling, the second blade rotating shaft 111 can transmit a rotational force from the driving shaft 11.

  A second kneading blade 120 (for example, an aluminum alloy die cast product) is attached to the upper end of the second blade rotating shaft 111. The second kneading blade 120 has a shape such that the above-described kneading blade 101 and the complementary kneading blade 102 (see FIGS. 6 to 8) are integrated, and the hub 121 is the upper end of the second blade rotating shaft 111. It is connected to non-rotatable.

  FIG. 10 is a diagram for explaining the relationship between the hub of the second kneading blade and the second blade rotation shaft in the second bread container, FIG. 10 (a) is a cross-sectional view, and FIG. 10 (b) is a cross-sectional view. It is a top view. The central hole of the hub 121 of the second kneading blade 120 is a circular hole 121a at a predetermined height from the lower end, and the upper part is a D-shaped hole 121b. The D-shaped hole portion 121 b has a step structure in which a lower portion corresponding to the D-shaped string projects toward the center of the second blade rotation shaft 111. On the other hand, the second blade rotating shaft 111 has a circular cross section up to a point where a distance is left to the upper end, and the upper portion is a D-shaped cross section 111b. Contrary to the D-shaped hole portion 121b, the D-shaped cross-sectional portion 111b has a stepped structure in which an upper portion of a portion that contacts the D-shaped string protrudes.

By combining the D-shaped hole portion 121b and the D-shaped cross-sectional portion 111b so that the protruding portion of the D-shaped cross-sectional portion 111b is overhanging with respect to the protruding portion of the D-shaped hole portion 121b, The hub 121 of the second kneading blade 120 is non-rotatably connected to the second blade rotating shaft 111. Since the hub 121 and the second blade rotating shaft 111 are sufficiently fitted, the second blade rotating shaft 111 can be passed through the hub 121 without any problem to obtain the overhanged state. Further, when power is transmitted to the second blade rotating shaft 111, as shown in FIG. 10B, the angle between the D-shaped hole portion 121b and the D-shaped cross-sectional portion 111b is shifted and the projecting portions are hooked. For this reason, the second kneading blade 120 does not easily come off from the second blade rotating shaft 111.
(Configuration of protrusion, movable part and guide part)
The schematic configuration of the automatic bread maker 1 of the present embodiment has been described above. Next, the configuration of the protrusions 84a and 84b, the guide portions 32a and 32b, and the movable portion 33 provided in the first bread container described above. Details will be described with reference to the drawings. In the following description, the first bread container 80 is inserted into the baking chamber 30 with the cut-out portion 84a facing the side wall 30b on which the guide portion 32a and the movable portion 33 are provided, for the sake of concrete description. (See FIG. 5).

  FIG. 11 is a perspective view showing the configuration of the protruding portion, the movable portion, and the guide portion when the first bread container is not housed in the housing position in the baking chamber, and shows the inside of the baking chamber 30 (first bread container). It is a figure at the time of seeing the side wall 30b from the side in which 80 can be accommodated. FIG. 12 is a perspective view showing the configuration of the movable portion when the first bread container is not housed in the housing position in the baking chamber, and is a view when the side wall 30b is viewed from the outside of the baking chamber 30. FIG. FIG. 13 is a perspective view illustrating the configuration of the protruding portion, the movable portion, and the guide portion when the first bread container is accommodated in the accommodating position in the baking chamber. It is a figure at the time of seeing the side wall 30b from the side in which the bread container 80 can be accommodated. FIG. 14 is a perspective view showing the configuration of the movable part when the first bread container is housed in the housing position in the baking chamber, and is a view when the side wall 30 b is viewed from the outside of the baking chamber 30.

  The lower side of FIGS. 11 to 14 is the bottom side of the baking chamber 30, and the upper side is the opening side (the lid 40 side) of the baking chamber 30. That is, the vertical direction in FIGS. 11 to 14 is the insertion direction and the removal direction of the first bread container 80. 11 and 13, for convenience of illustration, the side wall 80b (see FIG. 5) of the first bread container 80 is not displayed, and the surface of the projecting portion 84a connected to the side wall 80b is hatched. As shown.

  As shown in FIG. 11, the guide portion 32a has a predetermined width and extends in the vertical direction. Moreover, the guide part 32a protrudes inside the firing chamber 30 toward the lower side. Further, the protruding portion 84a has a cutout portion 85a having a width substantially equal to the width of the guide portion 32a (may be slightly larger than the width). And as shown in FIG. 13, if the 1st bread container 80 is inserted in the baking chamber 30 in the state which the notch part 85a and the guide part 32a fitted, the 1st bread container 80 will be in an accommodation position. The guide part 32a is arrange | positioned so that it may be accommodated.

  Further, as shown in FIG. 11, a long hole 301 is provided in the side wall 30 b of the baking chamber 30 in the vertical direction so that a contact portion 33 a that is a part of the movable portion 33 is communicated with the hole 301. The movable part 33 is arranged. Furthermore, at least a part of the contact portion 33a protrudes from the inner surface of the side wall 30b. And as shown in FIG. 13, when the 1st bread container 80 is inserted in the baking chamber 30 in the state which the notch part 85a and the guide part 32a fitted, the contact part 33a will be pushed by the protrusion part 84a. The hole 301 is arranged in the upper part.

  As shown in FIG. 12, a body portion 33 b that is a part of the movable portion 33 and is connected to the contact portion 33 a is disposed outside the side wall 30 b of the baking chamber 30. The body portion 33b is long along the vertical direction, and is provided with long holes 331 and 332 along the vertical direction, and the protrusions 302 and 303 fixed to the outside of the side wall 30b of the baking chamber 30 in the holes 331 and 332, respectively. (For example, a bolt having a nut attached to the tip) is passed. As shown in FIGS. 12 and 14, the movable portion 33 is configured to move along the vertical direction by the holes 331 and 332 and the protrusions 302 and 303.

  As shown in FIG. 12, a switch pressing portion 33c is connected to the lower side of the body portion 33b. Also, a micro switch 34 and an inclined portion 35 are provided in the vicinity of the switch pressing portion 33c. The inclined portion 35 has an inclined surface that approaches the microswitch 34 toward the lower side. Then, as described above, when the contact portion 33a is pushed downward by the protruding portion 84a, the movable portion 33 moves downward as shown in FIG. At this time, the switch pressing portion 33c is urged toward the microswitch 34 in order to contact the inclined surface of the inclined portion 35 and advance downward. As shown in FIG. 14, the microswitch 34 is arranged so that the button 341 is pressed (turned on) by the switch pressing portion 33c in this state.

  As shown in FIG. 12, one end of a spring (tensile spring) 36 is fixed on the upper side of the body portion 33b. The other end of the spring 36 is fixed to the side wall 30 b so as to be above the one end of the spring 36. That is, the movable portion 33 can be biased upward by the spring 36. At least, when the movable part 33 moves downward as shown in FIG. 14, an upward biasing force is generated by the spring 36. By this spring 36, when the first bread container 80 is detached from the baking chamber 30, the movable portion 33 moves upward, and the button 341 of the micro switch 34 returns (turns off).

As described above, in the present embodiment, the micro switch 34 serves as a first bread container detection unit that detects whether or not the first bread container 80 is accommodated in the accommodating position in the baking chamber 30. Yes. Specifically, the on state of the micro switch 34 indicates that the first bread container 80 is housed in the housing position in the baking chamber 30, and the off state of the micro switch 34 indicates that the first pan container 80 is housed in the housing position. It shows that the container 80 is not accommodated in the accommodating position in the baking chamber 30. In addition, it is confirmed whether the 1st bread container 80 is accommodated in the accommodation position in the baking chamber 30 by a simple mechanical structure by setting a 1st bread container detection means in such a structure. It becomes possible.
(Control of automatic bread machine)
FIG. 15 is a block diagram showing the configuration of the automatic bread maker of the present embodiment. As shown in FIG. 15, the control operation in the automatic bread maker 1 is performed by the control device 130. The control device 130 is configured by a microcomputer including a central processing unit (CPU), a read only memory (ROM), a random access memory (RAM), an input / output (I / O) circuit unit, and the like. .

The first solenoid drive circuit 134 controls driving of the automatic charging solenoid 16 that is driven when a part of the bread ingredients is automatically input during the bread manufacturing process under a command from the control device 130. Circuit. The second solenoid drive circuit 135 is a circuit for controlling the drive of the clutch solenoid 73 (see FIG. 4) that switches the state of the clutch 56 (see FIG. 4) under a command from the control device 130.

  The control device 130 reads a program relating to a bread manufacturing course (breadmaking course) stored in a ROM or the like based on an input signal from the operation unit 20, and a kneading blade by the kneading motor 50 via the kneading motor driving circuit 131. 101 and the complementary kneading blade 102 or the second kneading blade 120 are controlled to rotate, the crushing motor 92 is controlled to rotate by the crushing motor drive circuit 132 through the crushing motor driving circuit 132, and the heating operation by the sheathed heater 31 through the heater driving circuit 133. Control of the opening of the bread ingredient storage container 19 by the automatic charging solenoid 16 through the first solenoid drive circuit 134, and switching control of the clutch 56 by the clutch solenoid 73 through the second solenoid drive circuit 135. However, the automatic bread maker 1 executes the bread manufacturing process.

  Further, the control device 130 checks the state of at least one of the micro switch 34 and the magnetic sensor 17 as necessary, and detects an abnormality of the automatic bread maker 1. The control device 130 will be described later in detail with respect to the abnormality detection method performed by the control device 130 and the operation control method of the automatic bread maker 1 according to the abnormality detection result.

As described above, in the present embodiment, the control device 130 serves as an abnormality detection unit that detects whether there is an abnormality in the automatic bread maker 1.
(Operation of automatic bread machine)
Next, the operation in the case of producing bread with the automatic bread maker 1 configured as described above will be described. Here, the case where bread is produced by using an automatic bread maker 1 using grains such as rice grains as a starting material, and the case where bread is baked using powdered flour such as wheat flour and rice flour as starting materials are taken as examples. The operation of the automatic bread maker 1 will be described.

  FIG. 16 is a schematic diagram showing the flow of the rice grain bread course and the flour bread course executed by the automatic bread maker 1. FIG. 16 (a) shows the flow of the bread crumb for rice grains, and FIG. 16 (b) shows the bread crumb made of wheat flour. As described above, the first bread container 80 is used in the bread making course for rice grains whose starting material is grain grains, and the second bread container 110 is used in the bread bread course made of wheat flour whose starting material is grain flour. It is done.

  As shown in FIG. 16 (a), in the bread making course for rice grains, the dipping process, the crushing process, the pause process, the kneading process, the fermentation process, and the baking process are sequentially performed in this order. To be executed.

  When starting the rice grain breadmaking course, the user attaches the blade unit 90 to the blade rotation shaft 82 by covering the blade rotation shaft 82 of the first bread container 80 with the unit shaft 91. As described above, since the blade unit 90 includes the guard 106, the user's finger does not touch the crushing blade 92 during this work, and the user can work safely. After the operation of attaching the blade unit 90, the user weighs rice grains, water, and seasonings (for example, salt, sugar, shortening, etc.) in predetermined amounts and puts them in the first bread container 80. In addition, the user weighs a part of the bread ingredients that are automatically introduced during the manufacture of bread and puts them in the bread ingredient storage container 19.

  Examples of the bread ingredients stored in the bread ingredient storage container 19 include gluten and dry yeast. Instead of gluten, for example, at least one of flour, thickener (eg, guar gum), and upper fresh powder may be stored in the bread raw material storage container 19. Further, for example, only dry yeast may be stored in the bread raw material storage container 19 without using gluten, wheat flour, thickener, super fresh powder or the like. Further, in some cases, for example, salt, sugar, and shortening seasonings such as salt, sugar, and shortening are stored in the bread ingredient storage container 19 together with, for example, gluten and dry yeast, in order to automatically add them. May be. In this case, the bread raw material previously put into the first bread container 80 is rice grains and water (a liquid having a taste component such as dashi soup, a liquid containing fruit juice or alcohol, etc. instead of mere water). Good).

  Thereafter, the user puts the first bread container 80 into the baking chamber 30 and further fits the bread ingredient storage container 19 into the holding portion 45 of the lid 40. Then, the user closes the lid 40, selects the rice grain breadmaking course using the operation unit 20, and presses the start key. Thereby, the control apparatus 130 starts control operation | movement of the bread-making course for rice grain which manufactures bread using rice grain as a starting material.

  When the rice grain breadmaking course is started, the dipping process is started by a command from the control device 130. In the dipping process, the bread raw material previously put in the first bread container 80 is set in a static state, and this static state is maintained for a predetermined time (30 minutes in this embodiment). This dipping process is a process aimed at making the rice grains easy to be pulverized to the core in the subsequent pulverization process by adding water to the rice grains.

  The water absorption speed of rice grains varies depending on the temperature of the water. If the water temperature is high, the water absorption speed increases, and if the water temperature is low, the water absorption speed decreases. For this reason, you may make it fluctuate the time of an immersion process with the environmental temperature etc. in which the automatic bread maker 1 is used, for example. Thereby, it becomes possible to suppress the dispersion | variation in the water absorption degree of a rice grain. Further, in order to shorten the immersion time, the sheathed heater 31 may be energized to increase the temperature of the firing chamber 30.

  Further, the grinding blade 92 may be rotated at the initial stage of the dipping process, and further, the grinding blade 92 may be intermittently rotated thereafter. If it does in this way, the surface of a rice grain can be damaged, and the liquid absorption efficiency of a rice grain will be improved.

  When the predetermined time elapses, the dipping process is ended by a command from the control device 130, and the pulverizing process for pulverizing the rice grains is started. In this pulverization step, the pulverization blade 92 is rotated at a high speed (for example, 7000 to 8000 rpm) in a mixture containing rice grains and water. Therefore, in particular, this pulverization process needs to be performed safely.

  When the grinding blade 92 is rotated using the grinding motor 60, the control device 130 drives the clutch solenoid 73 so that the clutch 56 shuts off the power (the state shown in FIG. 4A). ). This is because, as described above, there is a possibility that the motor is damaged unless it is controlled in this way. It is preferable that the pulverizing blade 92 is rotated at a low speed in the initial stage of the pulverization process and then rotated at a high speed.

  In the crushing process, vibration is generated while the crushing blade 92 is rotating. However, since the cushioning material 107 is in contact with the first bread container 80, the collision sound generated by the vibration is reduced. It has come to be.

  The pulverization of the rice grains in the pulverization step is performed in a state where water is soaked in the rice grains by the previously performed immersion step, and thus the rice grains can be easily pulverized to the core. In the present embodiment, the rotation of the pulverizing blade 92 in the pulverization step is intermittent. This intermittent rotation is performed, for example, in a cycle of rotating for 30 seconds and stopping for 5 minutes, and this cycle is repeated 10 times. In the last cycle, the stop for 5 minutes is not performed. The rotation of the crushing blade 92 may be continuous rotation, but for the purpose of, for example, preventing the temperature of the raw material in the bread container 80 from becoming too high, it is preferable to perform intermittent rotation.

  In the automatic bread maker 1, the crushing process is completed in a predetermined time (in this embodiment, 50 minutes). However, the grain size of the pulverized powder may vary depending on the hardness of the rice grains and the environmental conditions. For this reason, the end of the pulverization process may be determined based on the magnitude of the load of the pulverization motor 60 (for example, it can be determined by the control current of the motor).

  When the pulverization process is completed, a pause process is executed according to a command from the control device 130. This pause process is provided as a cooling period during which the temperature of the contents in the first bread container 80 raised by the crushing process is lowered. The reason for lowering the temperature is that the next kneading step is carried out at a temperature at which the yeast is active (for example, around 30 ° C.). In the present embodiment, the pause process is a predetermined time (30 minutes), but in some cases, the pause process may be performed until the temperature of the first bread container 80 reaches a predetermined temperature. I do not care.

  When the pause process ends, the kneading process is started by a command from the control device 130. At the start of the kneading process, the control device 130 drives the clutch solenoid 73 so that the clutch 56 transmits power (state shown in FIG. 4B). Then, the control device 130 controls the kneading motor 50 to rotate the blade rotation shaft 82.

  The rotation of the blade rotation shaft 82 in the initial stage of the kneading process is preferably intermittent rotation or low speed rotation. When the kneading blade 101 is folded, the complementary kneading blades 102 are arranged on the extension of the kneading blade 101, so that the kneading blade 101 is pushed up as if the size is increased, and the dough is kneaded. This is preferable because it can be performed firmly.

  The rotation of the kneading blade 101 (this term is used as an expression including the complementary kneading blade 102 in the folded position, the same applies hereinafter) is very slow in the initial stage of the kneading process, and the speed is increased stepwise. Control is performed by the control device 130 as described above. In the initial stage of the kneading process in which the rotation of the kneading blade 101 is very slow, the control device 130 drives the automatic charging solenoid 16 to open the bread raw material storage container 19. Thereby, for example, bread ingredients such as gluten and dry yeast are automatically charged into the first bread container 80.

  In this embodiment, the bread ingredients stored in the bread ingredient storage container 19 are charged while the kneading blade 101 is rotating. However, the present invention is not limited to this, and the kneading blade 101 stops. You may throw it in However, it is preferable to add the bread ingredients while the kneading blade 101 is rotating as in this embodiment because the bread ingredients can be uniformly dispersed.

  After the bread ingredients stored in the bread ingredient storage container 19 are put into the first bread container 80, the kneading blade 101 rotates the bread ingredients into one dough having a predetermined elasticity. It will be crafted. When the kneading blade 101 shakes the dough and knocks it against the inner wall of the first bread container 80, an element of “kneading” is added to the kneading. As the kneading blade 101 rotates, the dome-shaped cover 93 also rotates. When the dome-shaped cover 93 rotates, the rib 93e formed on the dome-shaped cover 93 also rotates, so that the bread material in the dome-shaped cover 93 is quickly discharged from the window 93d and the kneading blade 101 kneads the bread. Assimilate into a lump of material.

  In the automatic bread maker 1, the time of the kneading process is configured to employ a predetermined time (10 minutes in the present embodiment) obtained experimentally as the time for obtaining dough having a desired elasticity. However, if the time of the kneading process is constant, the degree of bread dough may vary depending on the environmental temperature or the like. For this reason, for example, a configuration in which the end point of the kneading process is determined based on the magnitude of the load of the kneading motor 50 (for example, it can be determined by the control current of the motor) may be used.

  In addition, what is necessary is just to put it in the middle of this kneading process, when baking bread containing ingredients (for example, raisins, nuts, cheese, etc.).

  When the kneading process is completed, the fermentation process is started by a command from the control device 130. In this fermentation process, the control device 130 controls the sheathed heater 31 to maintain the temperature of the baking chamber 30 at a temperature at which fermentation proceeds (for example, 38 ° C.). Then, it is left for a predetermined time (in this embodiment, 60 minutes) in an environment in which fermentation proceeds.

  In some cases, during the fermentation process, the kneading blade 101 may be rotated to perform degassing or dough rounding.

  When the fermentation process ends, the firing process is started by a command from the control device 130. The control device 130 controls the sheathed heater 31 to raise the temperature of the baking chamber 30 to a temperature suitable for baking (for example, 125 ° C.). Then, the control device 130 performs control so that the bread is baked for a predetermined time (in this embodiment, 50 minutes) in the baking environment. The end of the firing process is notified to the user by, for example, a display on the output unit 21 of the operation unit 20 or a notification sound. When the user detects the completion of bread making, the user opens the lid 40 and takes out the first bread container 80 to complete the bread production.

  In addition, the bread in the 1st bread container 80 can be taken out by orienting the opening of the 1st bread container 80 diagonally downward, for example. Simultaneously with the removal of the bread, the blade unit 90 attached to the blade rotation shaft 82 is also removed from the first bread container 80. Due to the presence of the guard 106, the user does not touch the crushing blade 92 during the bread removal operation, and the user can safely perform the bread removal operation. At the bottom of the bread, the burn marks of the kneading blade 101 of the blade unit 90 and the complementary kneading blade 102 (projecting upward from the recess 81 of the first bread container 80) remain. However, since the dome-shaped cover 93 and the guard 106 are accommodated in the recess 81, they are prevented from leaving a large burn mark on the bottom of the bread.

  On the other hand, as shown in FIG. 16 (b), in a bread course made of flour, a kneading (kneading) process, a primary fermentation process, a degassing process, a dough resting process (also referred to as bench time or kneading), and dough A rounding process, a shaping fermentation process, and a baking process are sequentially performed in this order.

  In executing the bread course made of flour, the user attaches the second kneading blade 120 to the second bread container 110. Then, after a predetermined amount of water is put into the second bread container 110, a predetermined amount of flour, salt, sugar and shortening is added, and finally, the dry yeast is put into the second bread container 110 so as not to touch the water. Put in. Note that the amount of seasonings such as salt, sugar, and shortening may be appropriately changed according to the user's preference. Thereafter, the user puts the second bread container 110 into the baking chamber 30, closes the lid 40, selects a bread course made of flour by the operation unit 20, and presses the start key. Thereby, the bread | pan course made from flour which manufactures bread using flour as a starting material by the control apparatus 130 is started.

  When the flour bread course is started, the kneading process is started by a command from the control device 130. When the kneading process is started, the control device 130 controls the kneading motor 50 to rotate the second blade rotating shaft 111 in the forward direction. Thereby, the second kneading blade 120 is rotated at a low speed and a high torque. Note that the rotation of the second kneading blade 120 is controlled by the control device 130 so as to be very slow at the initial stage of the kneading process, for example, so that the speed is increased stepwise.

  Due to the rotation of the second kneading blade 120, the bread ingredients in the second bread container 110 are kneaded and kneaded into one dough having a predetermined elasticity. When the second kneading blade 120 swings the dough and knocks it against the inner wall of the second bread container 110, an element of “kneading” is added to the kneading. This kneading step is performed for a predetermined time (12 minutes in the present embodiment) experimentally obtained as a time for obtaining bread dough having a desired elasticity.

  In addition, what is necessary is just to put it in the middle of this kneading process, when baking bread containing ingredients (for example, raisins, nuts, cheese, etc.).

  When the kneading process is completed, a primary fermentation process for fermenting the bread dough is started according to a command from the control device 130. When this primary fermentation process is started, the control device 130 controls the sheathed heater 31 to maintain the temperature of the baking chamber 30 at a predetermined temperature (32 ° C. in this embodiment) at which fermentation proceeds. In this embodiment, the primary fermentation process is performed for 48 minutes and 50 seconds.

  When the primary fermentation process is completed, a degassing process for degassing the dough contained in the bread dough is started by a command from the control device 130. In this degassing step, the control device 130 controls the driving of the kneading motor 50 to continuously rotate the second kneading blade 120 for a predetermined time (in this embodiment, 10 seconds). In this degassing step, the control device 130 also controls the sheathed heater 31 to maintain the temperature of the firing chamber 30 at a predetermined temperature.

  When the degassing process is completed, a dough resting process (bench time; sometimes referred to as “nekashi”) for resting the dough according to a command from the control device 130 is executed. In this bench time, the control device 130 controls the sheathed heater 31 to maintain the temperature of the baking chamber 30 at a predetermined temperature (32 ° C. in the present embodiment). The bench time is performed in this embodiment (35 minutes and 30 seconds).

  When the dough resting process ends, a dough rounding process for rounding the bread dough is started according to a command from the control device 130. In this dough rounding process, the control device 130 controls the drive of the kneading motor 50 to rotate the second kneading blade 120. In the dough rounding step, the second kneading blade 120 is rotated very slowly for a predetermined time (1 minute 30 seconds in this embodiment).

  When the dough rounding process ends, a molding fermentation process is performed in which the bread dough is fermented again according to a command from the control device 130. In this molding fermentation process, the control device 130 controls the sheathed heater 31 to set the temperature of the baking chamber 30 to a predetermined temperature (38 ° C. in this embodiment) at which fermentation proceeds, and this state for a predetermined time (in this embodiment). 60 minutes).

When the molding fermentation process ends, a baking process for baking bread dough is executed according to a command from the control device 130. In this baking process, the controller 130 controls the sheath heater 31 to raise the temperature of the baking chamber 30 to a temperature suitable for baking (120 ° C. in this embodiment). Then, the bread is baked for a predetermined time (47 minutes in this embodiment) in a baking environment. The end of the firing process is notified to the user by, for example, a display on the output unit 21 of the operation unit 20 or a notification sound. When the user detects the completion of bread making, the user opens the lid 40 and takes out the second bread container 110 to complete the bread production.
(Abnormality detection operation)
Next, an abnormality detection operation in the automatic bread maker of the present embodiment will be described with reference to the drawings. FIG. 17 is a flowchart showing an abnormality detection operation before the automatic bread maker 1 starts a manufacturing course. FIG. 18 is a flowchart showing an abnormality detection operation after the automatic bread maker 1 starts a manufacturing course.
1. Before Manufacturing Course Start As shown in FIG. 17, in the abnormality detection operation before starting the manufacturing course, a manufacturing course is first selected by the user (STEP 1). At this time, the user can also specify (reserve) the execution time (for example, end time) of the selected manufacturing course via the operation unit 20. Specifically, for example, the control device 130 inserts a standby process at an arbitrary timing of the manufacturing course shown in FIGS. 16A and 16B (for example, at the beginning of the manufacturing course or before fermentation). Complete the bread making at the time the user wants. In this standby process, mechanical operation or heating operation of the automatic bread maker 1 is not performed in principle. In addition, the standby process can be interpreted as a part of a predetermined process (for example, a neglect process) depending on the insertion timing. Note that the standby process inserted at the time of the reservation also forms part of the manufacturing course. In other words, a manufacturing course with a reservation starts when the reservation is finalized (STEP 11 to be described later) even if the standby process is first performed.

  In STEP 1, the control device 130 confirms whether or not the first bread container 80 is accommodated in the accommodating position in the baking chamber 30 by confirming the state (ON or OFF) of the micro switch 34. It doesn't matter. Then, for example, when the control device 130 confirms that the first bread container 80 is accommodated in the accommodating position in the baking chamber 30, the manufacturing course in which the user uses grain flour as the starting material via the operation unit 20. When an instruction to select (for example, the above-described flour bread course) (for example, an instruction to display the flour bread course on the output unit 21) is input, an abnormality is detected and the output unit 21 is controlled to the user. The fact that the selection of the manufacturing course is abnormal (impossible) is notified. Further, for example, when the control device 130 confirms that the first bread container 80 is not accommodated in the accommodating position in the baking chamber 30, the user uses the operation unit 20 to start the grain from the grain. When an instruction to select a production course (for example, the above-described rice grain bread making course) (for example, an instruction to display the rice grain bread making course on the output unit 21) is input, an abnormality is detected and the output unit 21 is controlled. Then, the user is informed that the selection of the manufacturing course is abnormal (impossible). Furthermore, when the control device 130 detects the above-described abnormality, it may not accept the user's selection that is the cause of the abnormality.

  The control device 130 confirms the state (ON or OFF) of the micro switch 34 when a production course using the first bread container (for example, the above-described rice bread making course) is selected in STEP 1 (STEP 2, YES). Thus, it is confirmed whether or not the first bread container 80 is accommodated in the accommodating position in the baking chamber 30 (STEP 3). At this time, when the control device 130 confirms that the first bread container 80 is not accommodated in the accommodating position in the baking chamber 30 (the micro switch 34 is OFF) (STEP 3, NO), an abnormality is detected and output. The unit 21 is controlled to notify the user that the bread container is abnormal (STEP 4). For example, “CASE” is displayed on the output unit 21.

  Further, the control device 130 checks whether or not the state of detecting the abnormality has elapsed (or accumulated) time X (for example, 1 minute) (STEP 5). When the control device 130 confirms that the time X has elapsed (STEP 5, YES), the execution of the manufacturing course selected in STEP 1 is canceled (STEP 6), and the process ends. For example, the manufacturing course returns to an unselected state (standby state). When the control device 130 cancels the execution of the manufacturing course, the control unit 130 may control the output unit 21 to notify the user to that effect.

  On the other hand, when the control device 130 confirms that the time X has not elapsed (STEP 5, NO), the control device 130 returns to STEP 2 and continues to detect abnormality.

  Further, the control device 130 selects a manufacturing course using the first bread container in STEP 1 (for example, the above-mentioned rice grain bread making course) (STEP 2, YES), and the first bread container 80 is placed in the baking chamber 30. If it is confirmed that it is accommodated in the accommodation position (the micro switch 34 is on) (STEP 3, YES), it is confirmed whether or not the lid 40 is open by confirming the state of the magnetic sensor 17 (STEP 7). At this time, if the control device 130 confirms that the lid 40 is open (the magnetic sensor 17 does not detect the magnetic force of the permanent magnet 18) (STEP 7, YES), it detects an abnormality and controls the output unit 21. Inform the user that the lid 40 is abnormal (STEP 8). For example, “OPEN” is displayed on the output unit 21. Then, the control apparatus 130 performs STEP5 mentioned above.

  On the other hand, the control device 130 is also in the state of the micro switch 34 (STEP 2, NO) when a manufacturing course that does not use the first bread container in STEP 1 (for example, the above-described flour bread course) is selected (STEP 2, NO) By confirming “ON” or “OFF”, it is confirmed whether or not the first bread container 80 is accommodated in the accommodating position in the baking chamber 30 (STEP 9). However, at this time, if the control device 130 confirms that the first bread container 80 is accommodated in the accommodating position in the baking chamber 30 (the micro switch 34 is ON) (STEP 9, YES), an abnormality is detected. Then, the above STEP 4 is performed. On the other hand, when the control device 130 confirms that the first bread container 80 is not accommodated in the accommodating position in the baking chamber 30 (the micro switch 34 is OFF) (STEP 9, NO), the above STEP 7 is performed.

  By the way, if the control device 130 confirms that the lid 40 is closed at STEP 7 (the magnetic sensor 17 detects the magnetic force of the permanent magnet 18) (STEP 7, NO), it is assumed that no abnormality is detected, and the time of the manufacturing course. Adjustment is performed (STEP 10). The time adjustment of the manufacturing course is, for example, the time required for the user to eliminate the abnormality (the time when the start of the manufacturing course is delayed) when the control device 130 detects the abnormality as described above. This is reflected in the operation control. For example, the control device 130 calculates a new end time by adding the above time to the end time of the manufacturing course that has been calculated so far. At this time, the control device 130 may notify the user of the new end time by controlling the output unit 21. In addition, the control apparatus 130 is a process that can be shortened in the manufacturing course (a process that does not easily affect the degree of completeness of bread and the safety of the automatic bread maker 1 even if shortened, for example, a manufacturing course with reservation If there is a standby process, the end time may be maintained by shortening the process.

  And the control apparatus 130 will start a manufacturing course, if the time adjustment of a manufacturing course is performed by STEP10 as needed (STEP11).

  When the control device 130 performs the abnormality detection operation as described above, for example, the first bread container 80 and the second bread container 110 may be mistaken or the first bread container 80 may be accommodated in the baking chamber 30. It is detected as abnormal that it is not contained in (a position where it can operate correctly) and that the lid 40 is open. Further, the control device 130 detects the presence or absence of this abnormality before starting the manufacturing course. Therefore, it is possible to suppress that the manufacturing course is executed and the safety is impaired in such an abnormal state.

  Further, when the time X elapses in a state where the control device 130 detects an abnormality, the manufacturing course can be canceled without being executed. For this reason, it is possible to suppress waiting in vain when the abnormality is not resolved.

  In the example shown in FIG. 17, whether the abnormality of the bread container or the lid 40 is detected, the passage of the common time X is confirmed, but each abnormality is detected. You may check the passage of different times.

In addition, the control device 130 adjusts the time of the manufacturing course when the start of the manufacturing course is delayed due to the detection of an abnormality. For this reason, it is possible to prevent the manufacturing course from being shortened and the degree of completion of bread and the like from being reduced, and the safety of the automatic bread maker 1 from being reduced. Furthermore, even if the end time of the manufacturing course is delayed, the control device 130 controls the output unit 21 to notify the user of the correct end time. Therefore, the user can recognize the correct end time.
2. After the start of the manufacturing course As shown in FIG. 18, in the abnormality detection operation after the start of the manufacturing course, first, it is confirmed whether or not there is a timing at which the control device 130 should detect an abnormality (hereinafter referred to as an abnormality detection timing) ( (STEP110). The abnormality detection timing is before performing a process that requires ensuring safety or during the process. This process includes at least a pulverization process. Such a process may be included only in the manufacturing course using the first bread container 80 and may not be included in the manufacturing course using the second bread container 110. However, in the following, for the sake of generalization of the description, it is assumed that the manufacturing course using the second bread container 110 includes a process that requires ensuring safety.

  When the control device 130 confirms that it is an abnormality detection timing (STEP 110, YES), if a manufacturing course using the first bread container (for example, the above-described rice bread making course) is being executed (STEP 111, YES), it is confirmed whether or not the first bread container 80 is accommodated in the accommodating position in the baking chamber 30 by confirming the state (ON or OFF) of the micro switch 34 (STEP 112). At this time, when the control device 130 confirms that the first bread container 80 is not accommodated in the accommodating position in the baking chamber 30 (the micro switch 34 is OFF) (STEP 112, NO), the abnormality is detected and executed. Stop production course inside. Further, the control device 130 controls the output unit 21 to notify the user that the bread container is abnormal (STEP 113). For example, “CASE” is displayed on the output unit 21.

  Further, the control device 130 confirms whether or not the state of detecting an abnormality has elapsed (or accumulated) time Y (for example, 10 minutes) (STEP 114). When the control device 130 confirms that the time Y has elapsed (STEP 114, YES), the execution of the manufacturing course that has been stopped is stopped, and the output course 21 is controlled to stop the manufacturing course. Is notified to the user (STEP 115), and the process ends.

  On the other hand, when the control device 130 confirms that the time Y has not elapsed (STEP 114, NO), the control device 130 returns to STEP 110 and continues to detect abnormality.

  Moreover, the control apparatus 130 confirms that it is an abnormality detection timing (STEP110, YES), and is running the manufacturing course (for example, the above-mentioned rice breadmaking course) using a 1st bread container (STEP111, (YES), when confirming that the first bread container 80 is accommodated in the accommodating position in the baking chamber 30 (microswitch 34 is ON) (STEP 112, YES), by confirming the state of the magnetic sensor 17, It is confirmed whether or not the lid 40 is open (STEP 116). At this time, when the control device 130 confirms that the lid 40 is open (the magnetic sensor 17 does not detect the magnetic force of the permanent magnet 18) (STEP 116, YES), the abnormality is detected and the current manufacturing course is stopped. To do. Further, the control device 130 controls the output unit 21 to notify the user that the lid 40 is abnormal (STEP 117). For example, “OPEN” is displayed on the output unit 21. Then, the control apparatus 130 performs STEP114 mentioned above.

  On the other hand, the control apparatus 130 confirms that it is an abnormality detection timing (STEP110, YES), and is executing the manufacturing course (for example, the above-mentioned flour bread course) which does not use a 1st bread container. In the case (STEP 111, NO), the above-described STEP 116 is performed.

  By the way, when the control device 130 confirms that the lid 40 is closed in STEP 116 (the magnetic sensor 17 detects the magnetic force of the permanent magnet 18) (STEP 116, NO), it is assumed that no abnormality is detected, and the time of the manufacturing course. Adjustment is performed (STEP 118). This time adjustment of the manufacturing course is, for example, the time required for the user to resolve the abnormality when the control device 130 detects the abnormality as described above (the time taken from the stop of the manufacturing course to the resumption). ) And the time required for stopping and resuming the manufacturing course (when there is a process redo or addition, the time required for the process) is reflected in the operation control. For example, the control device 130 calculates a new end time by adding the above time to the end time of the manufacturing course that has been calculated so far. At this time, the control device 130 may notify the user of the new end time by controlling the output unit 21. In addition, the control apparatus 130 is a process that can be shortened in the manufacturing course (a process that does not easily affect the degree of completeness of bread and the safety of the automatic bread maker 1 even if shortened, for example, a manufacturing course with reservation If there is a standby process, the end time may be maintained by shortening the process.

  And the control apparatus 130 adjusts the time of the manufacturing course of STEP118 as needed, and will be complete | finished if the manufacturing course is complete | finished (STEP119, YES). On the other hand, if the manufacturing course has not ended yet (STEP 119, NO), the control device 130 resumes the manufacturing course that is continuing or stopped (STEP 120), returns to STEP 110, and detects an abnormality. Continue.

  In addition, the control apparatus 130 performs above-mentioned STEP119, when confirming that it is not abnormality detection timing (STEP110, NO).

  When the control device 130 performs the abnormality detection operation as described above, for example, the first bread container 80 is not accommodated in the accommodation position (position where it can operate correctly) in the baking chamber 30, or the lid 40 is Openness is detected as an abnormality when the crushing process is performed. Therefore, it is possible to further improve the safety of the pulverization process.

  Further, the manufacturing course can be stopped when the time Y elapses while the control device 130 detects an abnormality. For this reason, it is possible to suppress waiting in vain when the abnormality is not resolved.

  In the example shown in FIG. 18, whether the abnormality of the bread container or the lid 40 is detected, the passage of the common time Y is confirmed, but each abnormality is detected. You may check the passage of different times.

  In addition, the control device 130 stops the execution of the manufacturing course by detecting an abnormality, and adjusts the time of the manufacturing course when restarting after the abnormality is no longer detected. For this reason, it is possible to prevent the manufacturing course from being shortened and the degree of completion of bread and the like from being reduced, and the safety of the automatic bread maker 1 from being reduced. Furthermore, even if the end time of the manufacturing course is delayed, the control device 130 controls the output unit 21 to notify the user of the correct end time. Therefore, the user can recognize the correct end time.

As described above, in the automatic bread maker 1 that manufactures bread using cereal grains as a starting material, it is necessary to ensure safety in the crushing process in which the crushing blade 92 rotates at high speed. In the automatic bread maker 1 of the present embodiment, since the control device 130 detects the presence or absence of an abnormality in the crushing process, safety in the crushing process can be ensured. Therefore, the automatic bread maker 1 of this embodiment can manufacture bread safely.
