Automatic extractor technical field

 The present invention relates to an automatic extractor in which an extract is taken out by pouring into an extract such as coffee powder contained in a filter, and the extract is taken out and stored in a cup. Background art

 A coffee maker that pours hot water into coffee grounds in a filter to extract coffee liquor has been known for a long time, and paper and flannel are used as filter materials.

 Paper filters are used after they have been filtered and then stored in a cup as they are. However, since the filter is coarse and the whole is filtered at once, there is a drawback that the extraction time is short but the taste is light.

 On the other hand, Cloth Nelfill Yuichi has fine eyes and slowly filters, so the extraction time will be slightly longer, but it will be extracted from one point at the bottom, making it the best coffee with astringent taste, high taste and aroma. The feature is that it can be extracted.

 However, the extraction method using a flannel filter cannot extract the optimum coffee as described above simply by pouring near the center of the filter.

 For this reason, for business use and enthusiasts, the pouring locus of the hot water poured into the hot water pot on the coffee powder stored in the flannel filter draws the shape of a “no”.

 When the hot water is extracted by such a pouring method, the hot water is uniformly poured into the entire area of the coffee powder, so that the coffee powder can be used for the extraction without unevenness, and the even hot water is poured into the coffee powder, and It is said that the hot water poured into the coffee powder stays in the Nelfill Yuichi for a short time, so that it can perform a sufficient amount of mustard and extract a fragrant, rich and rich coffee liquid. I have.

The pouring method as described above is based on the pouring range and the route of the “no” depending on the user, even if the user knows the basic procedure of pouring hot water from the pouring pot into the coffee powder while drawing the “no” character. It is possible to always extract the optimal coffee liquid with a constant taste, aroma, and richness. Did not.

 Of course, in the coffee manufacturing apparatus disclosed in Japanese Patent Application Laid-Open No. Hei 9-128574, the coffee liquid can be automatically extracted, but it is not a pouring method that draws a "no" character. .

 In other words, the pouring method that draws the “no” character as described above seems to be simple at first glance, but the Japanese character “no” character is added to coffee powder stored in a flannel filter that is not so large in area. It is difficult to pour hot water while drawing while drawing, and it is difficult for an amateur to pour hot water with a normal kettle or pouring pot. Disclosure of the invention

I have. The shafts (12) and (16) of the first motor (10) and the second motor (14) are arranged to be orthogonal.

 (18) is a first photointegrator for fixing the pouring pipe (7) in the X-axis direction by fixing the same to the first metal fixing bracket (8) via a mounting stay (19); ), The circuit output becomes “L” when the shutter (13) blocks the optical path, and the circuit output becomes “H” when the optical path is opened.

 Reference numeral (21) denotes a second photointerrupter fixed to the second motor fixing bracket (11) via a mounting stay (22) to detect the position of the pouring pipe (7) in the Y-axis direction. The circuit output becomes “L” when the shirt Yiichi (17) blocks the optical path, and becomes “H” when it is opened, as in the case of the first photointerrupt (20).

 FIG. 3 is an explanatory view of the operation of the swing mechanism (5) when FIG. 2 is viewed from the direction of the arrow. The pouring is performed by simultaneously driving the first motor (10) and the second motor (14). The pipe (7) swings simultaneously in the X-axis direction and the Y-axis direction.

 FIG. 4 is a flowchart showing the pouring operation, and FIG. 5 is a plan view showing a pouring locus in which the hot water from the pouring port is drawn in the shape of the Japanese character "".

 With reference to FIGS. 1 to 5 described above, the pouring operation in the shape of the “no” will be described. First, place the cup (C) on the base (2), attach the filter (4) containing a predetermined amount of coffee powder to the holder (3), and operate the extraction button. The pouring valve ((23) in Fig. 4) provided between (7) and (7) is opened (S1), and at the same time, the timer ((24) in Fig. 4) executes the pouring process. Start counting time. (S2).

The opening of the pouring valve (23) activates the pouring pump (25) to pour the hot water from the hot water tank into the hot water tank (S3), and the pouring program by the microcomputer. Run. (S4).

 This pouring program is activated by the operation of the first mode (10) and the second mode (14).

(S5), the pouring pipe (7) swings, and the hot water poured from the pouring port (6) flows from the center (S) of the filter (4) as shown in the trajectory diagram in Fig. 5. The hot water is started, and while turning in a spiral shape, it passes through the black-painted area and performs the Japanese character “no” pouring.

 (S6).

 The pouring of the Japanese character “no” as described above is performed by a microcomputer program, but the “no” character is based on the standard cup (C) diameter. It is programmed to draw a small “no” with a diameter of about 40 mm.

 The specific method of pouring the “no” is that the first turn of the “no” is a filter that contains coffee powder (K) at the lower end of the pouring port (6) in the initial state of pouring. (4) center point

(5), pouring is started from this point (S), and the pouring port (6) is moved in the X-axis and Y-axis directions so as to draw a “no” in the direction of the arrow. Then, while slightly changing the direction of movement of the pouring port in the X-axis direction and the Y-axis direction, pouring it in a spiral shape over the extension of the “_” character, Draw a circle and return to the original position (center point S) at point (P) as shown in arrow direction A, and complete one revolution of the "no" pouring.

 The second "no" pouring is two revolutions, the third "no" pouring is 2.5 revolutions, the fourth "no" pouring is one revolution, the second At the third pouring, the pouring port (6) moves to the position of the center point (S) again, and continues pouring while following the same trajectory as the previous time.

 However, at the time of the third pouring, the pouring point is at the point (Q) where the third "no" pouring has started.

(6) is returned to the original position (center point S), and the extraction process for one cup is completed with a total of 6.5 rotations. (S7).

 The timer (24) described above counts the time during which the 6.5-turn “no” pouring is performed. When 6.5 turns are completed, the timer stops counting and the pouring pump (2) The operation of 5) is stopped (S8), (S9). At the same time, the operations of the first motor (10) and the second motor (14) are stopped, and all the steps are completed (S10).

Fig. 18 shows a schematic diagram of the automatic extractor system. This drawing shows a hot water temperature sensor with a heater (26) attached to the top of the extractor body and fixed to the bottom, and attached to the side wall. (27) to maintain a low temperature of about 50 degrees, a hot water storage tank (29) for storing hot water of about 10 liters with a water supply port (28) at the top, and a drainage port (300) at the top, There is a water tank (32) that holds about 1 liter of hot water with a water heater (30) in close contact with the bottom and maintains a high temperature of about 95 degrees by a water sensor (31) provided on the side wall. The drain port (300) drains when the amount of hot water in the boiling water tank (32) exceeds a certain amount.

 (33) is a hot water supply pipe connecting the lower part of the hot water storage tank (29) and the upper part of the hot water tank (32), and (34) is provided in a part of the hot water supply pipe (33). ) This is a hot water supply pump that supplies hot water in the hot water tank (32).

 As shown in Fig. 18, the relationship between the hot water level in the boiling water tank (32) (F: height of the drain port) and the lower end of the pouring port (6) is as shown in Fig. 18. The height from the lower end of () is represented by (H), and this height (H) is constant based on the constant amount necessary for extraction based on the amount of coffee powder and the optimal pouring time.

That is, by maintaining the height (H), if only the pouring time is controlled, the required amount of hot water at each pouring can be taken out. In ^{H = (1/2) gV 2,} (g) is the gravitational acceleration (constant), at a hot water rate falling from (V) is pouring port, and maintain a constant (H) (V) is the always constant It means that it becomes.

 A rocking mechanism (5) is linked to the pouring port (6), so that the coffee powder stored in the filter (4) can be poured in the shape of "no". By operating the pouring button provided on the side wall, a delay device (not shown) is activated to open the pouring valve (23), and after a predetermined time delay, the swing mechanism (5) is activated. Prevents the swinging mechanism (5) from operating even though coffee is not poured from the gate (6).

 The swing mechanism (5) shown in FIG. 2 is set so that the pouring port (6) is always located at the center of the filter (4) in the initial state at the start of pouring.

FIG. 6 is an enlarged view showing the coordinates of the area near the start of pouring of the pouring trajectory of the pouring port. In particular, this figure operates the first motor and the second motor based on a plurality of coordinate points defined in advance by the X-axis coordinate and the Y-axis coordinate. A letter is formed. Fig. 15 shows such coordinate points in a table. In the neutral position where the pouring pipe (7) is at rest, the pouring port (6) is set to the coordinate point NO, X axis 0, Y axis 0 Based on the setting of the coordinate point (a), the first mode (10) and the second mode (14) oscillate in one direction by (–1) by the output of the microcomputer. Hot water in the tank (29) is poured from the lower end of the pouring pipe (7) toward coffee powder along coordinate points (0) to (a).

 After that, the hot water to be poured from the pouring port (6) is swung right and left as shown by the two-dot chain line in FIG. 3 by rotating the first motor (10) and the second motor (14) according to the coordinate points in FIG. The pouring is performed in such a way as to draw a “J”, and after several vortex pouring, the process returns to the coordinate point (0) and the pouring process is completed.

 Therefore, the hot water poured at the coordinate points (0) and (a) penetrates into the coffee powder while the pouring pipe (7) is pouring while moving to other coordinate points, As a result, the hot water poured into each part of the coffee grounds before the end of the series of pouring steps is extracted after permeating the coffee grounds, and the extracted liquid of the first poured part falls first. After that, it is combined with the extract of the part that has been poured later and drops and is stored in the cup (C).

 FIG. 7 is a flow chart in which the position of the pouring pipe is corrected to the operating origin of the “no” pouring operation at the beginning of the coffee brewing operation.

 By operating the pouring button, the pouring valve (35) is opened to guide the hot water in the hot water tank (32) to the pouring pipe (7), and at the same time, based on the contents of the program pre-input to the microcomputer. Apply voltage to the first and second modes (10) and (14) to operate. At this time, if the pouring pipe (7) is originally located at the point (S) shown in Fig. 5, pouring is performed at a predetermined position along the pouring locus shown in Fig. 5. However, due to the nature of the motor, a time lag occurs between the start of rotation and the transmission of the rotational energy directly to the pouring pipe (7).

 This time lag will prevent the spiral pouring of the "no" pouring along the coordinate points based on Figure 15.

In order to prevent the above-mentioned phenomenon, the position of the shutter (13) by the first photo input / output (20) at the same time as the operation of the extraction button, ie, the first mode (1) The position of the shaft (12) of (0) is determined. If the shutter (13) blocks the optical path, the output becomes “H” and the first motor (10) is in the correct position. When the detection is performed by the photointegrator (20), there is no rotation of the first motor (10) in the reverse direction, and the output of the first photointegrator (20) is “L” immediately. By rotating the shutter (13) in the forward direction of the first motor (10) and displacing the shutter (13) to open the optical path, the output of the first photointerrupter (20) is set to “H”. Since it is the origin (S) shown in (1), the rotation of the first motor (10) is stopped and the pouring pipe (7) is corrected to the origin.

 After the above operation is instantaneously performed at the beginning of the extraction operation, the hot water coming out of the pouring pipe (7) is poured from the origin (S) to the vicinity of the center of the coffee powder (K), and then poured according to the microcomputer program. The pipe is swung in the X-axis direction by the first motor (10), and is swung in the Y-axis direction by the second motor (14). Do hot water.

 If the output of the first photointegrator (20) to be determined first is “H”, the first motor (10) is rotated in the reverse direction to rotate the first photointerrupter (20). Output is set to “L” to perform origin correction in the X-axis direction.

 Of course, the second motor (14) also performs the determination and operation shown in Fig. 7 in the same manner as the first motor (10), and performs the origin correction in the Y-axis direction.

 Therefore, the pouring pipe (7) has a spiral “no” character that is automatically corrected to the origin (S) by the first and second photo interrupters (20) and (21) at the beginning of coffee extraction. Perform pouring.

 As shown in Fig. 2, the first Photo Interlab evening (20) and the shirt Yuichi (13), and the second Photo In evening evening (21) and the shutter (17) are the first and second models, respectively. The position detectors (35) and (36) for setting the start positions of the evening (10) and (14) are configured.

FIG. 8 and FIG. 9 show flowcharts in which the pouring port is corrected to the origin position after the spiral-shaped turning operation is completed. When power is applied to the operation board (the board that starts the operation of the pouring mechanism) (S11), the first motor (10) and the second motor (14) rotate, and the “no” shape pouring is performed. Origin determination means (3) to determine the initial operating position to start 7) and (38) operate.

 This operation is performed as follows. After turning on the power to start pouring, the position of the actuator (15) indirectly connected to the first model (10) (the position of the pouring pipe (7) in the X-axis direction (left and right directions)) An important point at this time is that Mo-Yu itself has a structural provision. This is a characteristic of the so-called play of the shaft (12), which greatly affects the position of the pouring port (6) of the pouring pipe (7).

 For this reason, when a signal for starting the pouring operation (operation of the extraction button) is input, it is necessary to start the rocking of the pouring pipe (7) without any play at all. —The origin determination means (37) and (38) execute both in the evening and in the second mode. Thus, when the shirt Yuichi (13) closes the optical path (S12), the output of the first photo lab (20) becomes “H” (S13), and The first motor (10) is rotated in the reverse direction (S14), and when the simultaneously rotating shutter (13) opens the optical path, the first motor is rotated forward to detect the closing and opening of the optical path again. (S15, S16).

 When the optical path is closed by the forward rotation of the first motor, the output of the first photointerrupter (20) becomes "H" (S16, S17), and the rotation of the X motor stops. (S18).

 This completes the origin determination means (37) on the first motor (10) side, and determines the origin in the X-axis direction before the pouring port (6) performs the pouring operation ("-"-shaped turning operation). I do. After the work of the origin determination means (37) in the X-axis direction described above is completed, the origin in the Y-axis direction is determined. In the determination of the origin in the Y-axis direction, Yuichi Shirt (17) closes the optical path, The process starts with a determination as to whether it is open or not (S19). If the optical path is closed, the output of the second photointerrupter (21) becomes "H" (S20) and the second motor (14) ) Is rotated in reverse (S21), and when the shutter (17) rotates to open the optical path, the second motor (14) is rotated forward to detect the closing of the optical path. (S22, S23).

 When the optical path is closed and the output of the second photointerrupter (21) becomes “H”, the rotation of the second motor — evening (14) is stopped (S24, S25), and the rotation of the second motor (14) is stopped. The work of the origin determination means (38) is completed, and the origin in the Y-axis direction is determined before performing the pouring operation.

The origin in the X-axis direction and the Y-axis direction is determined and the origin is finally determined. After the origin determination by means of the above-mentioned origin determination means (37) and (38), whether deviation from the center of the filter (4) has occurred by visual inspection of a heated worker or by a predetermined template or gauge Detect (confirm) whether it is. For example, when the pouring port (6) is displaced in the X-axis direction (+5) and in the Y-axis direction (+5) (S26) as shown in Fig. 16, Using a dedicated compensator (not shown), input the adjustment values in the X-axis direction (1-5) and in the Y-axis direction (-5) to the microcomputer. (S27).

 The adjustment value data input to the microcomputer is stored in the storage means (39). (S

28).

 The amount of deviation as described above may be caused by the slight displacement of the components constituting the swing mechanism (5) and the displacement of the mounting position of the holder (3) after assembly of the individual extractor bodies (1). Although it varies greatly depending on the factors, adjustments are made based on the table shown in Fig. 15. Thus, when it is detected that the extraction button has been operated after inputting the adjustment value of the origin correction (S29), each of the first motor (10) and the second motor (14) operates, and the first motor (14) operates. In Mo (10), the pouring port (6) is moved in the X-axis direction (+5), and in the second mo (14), the pouring port (6) is moved in the Y-axis direction (+5) (S 30), (S31), the work of the origin adjustment means (40) is completed.

 Next, when extracting coffee, after operating the extraction button described above, maintain the hot water temperature in the hot water tank (32) at about 95 ° C, and reduce the hot water temperature in the hot water storage tank (29) to about 75 ° C. When it is held in the pouring port (6), the pouring valve (35) provided in the water channel of the hot water tank (32) is opened, and the hot water in the hot water tank is filled from the pouring port (6). From the “0” position in Fig. 16 which is the center of Yuichi (4), pouring is performed while turning in the shape of a “no”. (S32).

 Of course, when the amount of hot water in the hot water tank (32) decreases, the hot water supply pump (34) operates to supply hot water in the hot water storage tank (29) to the hot water tank (32). (S33).

 At this time, the pouring trajectory of the pouring port moves in the order of points "0", "a", "b", ~ "Q" ". (S

34).

When the first "no" pouring is completed (S35), the pouring operation is stopped for a short period of time, not shown, and then the first and second modes (10), (14) When activated, a predetermined number of "no" pouring is performed (S36), and a predetermined number of pouring operations are completed with a time lag between the respective times to complete a series of extraction steps. (S37), (S38) „

 Of course, at the time of executing the next extraction process, the origin is automatically corrected because it is stored in the storage means (39).

 FIG. 17 is a side view in which a pouring pipe is formed by connecting an upper pipe and a lower pipe. The pouring pipe (7) is composed of two pipes, an upper pipe (41) and a lower pipe (42), which are cascaded up and down, and each pipe is connected by a flexible joint (43) and integrated. Is becoming

 The joint (43) has an upper receiving portion (4) to which the lower end of the upper pipe (41) is fitted.

 By connecting the upper pipe (41) and the lower pipe (42) with the flexible joint (43) in this way, even if the hand accidentally touches the lower pipe, the swinging device is affected. The lower pipe returns to its original position.

 FIG. 19 is a schematic diagram of the whole in which the hot water tank (32) and the hot water storage tank (29) are connected by an overflow pipe. (51) is an overflow pipe that connects the inside of the hot water storage tank (29) with the inside of the hot water tank (32), and connects the water intake part (52) at one end to the upper part of the side wall of the hot water tank (32) and connects the other. The drain (53) at the end is connected to the space (54) at the upper inside of the hot water storage tank (29), and the position of the water intake at one end is such that the remaining hot water level in the water heater tank is always at the specified water level. It is set to secure the required amount of hot water.

(55) is an outlet pipe connecting the inside of the hot water storage tank (29) and the inside of the hot water tank (32), and the opening (56) at one end is taken from the intake part (52) of the overflow pipe (51). And the opening (57) at the other end is placed above the water surface of the hot water storage tank (29). It is connected to the empty space (54).

 In such a system, in the standby state where extraction is not being performed, the temperature of the hot water in the hot water tank (32) is generated by the hot water heater (30) by the hot water sensor (31), and the water stops (Z-stop). Although it is kept at a high temperature of about 95 degrees in the vicinity, bubbles generated at the time of boiling water and waves of the surface of the water generated due to boiling water flow through the intake section (52) of the overflow pipe (51). If the extraction button is accidentally operated and pouring is performed when it is closed, the air in the hot water tank (32) is sucked in through the outlet pipe (55) and the negative pressure in the hot water tank (32) is drawn. Prevent pressure.

 In Fig. 19, approximately 1 liter of hot water stored in the hot water tank (32) is controlled by the hot water heater (30) so that the hot water sensor (31) always keeps it at about 95 degrees. At the same time, about 10 liters of hot water stored in the hot water storage tank (29), the hot water supply pump (34) is stopped by the hot water temperature sensor (27).

 That is, when the temperature of the hot water in the hot water storage tank (29) detected by the hot water temperature sensor (27) is 75 degrees or less, the hot water supply pump (34) is operated to derive the hot water in the hot water storage tank (29). Water is supplied to the hot water tank (32) via 55). (56) is a hot water pipe connecting the upper side wall of the hot water tank (32) and the upper side wall of the hot water storage tank (29). As described above, the hot water fed into the boiling water tank (32) overflows from the overflow pipe (51) or the hot water pipe (51) in order to exceed a certain water level. ).

 In this way, the hot water supply pump (34) continues operating until the temperature of the hot water in the hot water storage tank (29) reaches 75 degrees, and the hot water in the hot water storage tank (29) is poured into the hot water tank (32). The hot water in the hot water tank (32) is put into the hot water storage tank (29) and circulated.

 The hot water temperature sensor (27), which detects that the temperature of the hot water in the hot water storage tank (29) has reached 75 degrees, stops the operation of the hot water supply pump (34) based on the output.

 In the description of FIG. 19, each of the overflow pipe (51) and the hot water pipe (56) connects the hot water storage tank (29) and the hot water tank (32). One flow pipe (51) may be used as a single pipe and used as a hot water pipe.

In such a configuration, the heater (26) of the hot water storage tank (29) shown in FIG. Can be eliminated. In other words, a large amount of hot water can be raised to a temperature suitable for extraction by using only one hot water heater (30) provided in the hot water tank (32). Can be extracted continuously.

 FIG. 10 and FIG. 4 are front views of a more specific configuration of the extractor main body (1). (57) (57) (57) is a plurality of swing mechanisms (5) (5) (5) and pouring pipes (7) (7) , Multiple holders (3) (3) (3) for detachably holding large and small filters (4a) (4b), and guides (58) (58) (58) for slidably holding these holders It consists of

 The holders (3), (3) and (3) consist of three sets, each of which is arranged in the horizontal direction, and the middle holder is a filter for one person (4a) and a filter for three persons by switching attachments. Filter 1 (4b) can be selected. The middle holder can be replaced with a filter for one person and a filter for three people, and the holders on both sides are dedicated to a filter for one person. (59a) and (59b) are provided on the front and rear sides of the upper part of the extractor body (1) where the middle fill is located, and constitute the operating means for setting the pouring amount to one or two persons. A pouring amount setting means, which is two setting buttons, includes a program for controlling the opening / closing time of the pouring pipe (35) (35) (35), and a swing mechanism (5) for performing pouring of "NO". ) (5) (5).

 The coffee grounds (beans) required to extract one coffee liquor are about 12 to 14 grams, and this weight of coffee grounds is stored in a one-person filter (4a). I do. The coffee grounds needed to extract the coffee liquid for three people are about 30 to 40 grams, and the filter (4b), which holds this much, is a filter for one person. a) It becomes larger than the outside diameter.

 As described above, the outside diameter of the filter for one person and three persons (4a) and (4b) is larger for the filter for three persons than for the one person. Because of the large size, it is necessary to correspond to the size of the trajectory of the "no" pouring by the assembly unit, and when set for one person, the trajectory size is set to "small" and set for three people In this case, the track size is set to “large”.

Figure 20 shows a float that removes the required amount of coffee liquid in a single pouring operation. It indicates lb-yat. Now, fill Yuichi (4a) containing coffee powder for one person in the middle holder (3), and place a cup (Ca) for one person below Fill Yuichi (4a). When the setting button (59a) for one person is selected and operated (S40) in the state of being placed on the (S40), it is determined that the microcomputer contained therein is for one cup (S41), The pouring volume is set to approximately 160 cc, which is appropriate for one person (S42).

 The setting of the pouring amount is carried out by shortening (opening) the opening time of the pouring valve (35) (S43), and simultaneously with the first motor (10) integrated as an assembly unit. And the second motor (14) are activated, and the pouring pipe (7) attached to the actuator (15) changes the shape of the "no" as shown in Fig. 5 according to the operation time and operation timing of each motor. Pour the coffee powder into the filter (4a) while drawing.

 The “NO” character pouring locus size is set to “Small” according to the filter size for one person (S44), the pouring operation is performed (S45), and a series of “NO” character pouring is performed. After performing, the extraction is terminated. (S46), (S47).

 At the time of pouring of the above-mentioned `` no '', the pouring operation is not actually performed continuously, but the pouring is stopped for a few seconds after one rotation, and then stopped again for two seconds after turning twice. Then, there is a series of processes to stop pouring after several revolutions and to perform murata, but of course, the series of processes for one person and three people is slightly different, and in the case of three people, The number of revolutions and pouring time are set longer.

 Next, as shown in Fig. 10, a filter (4b) containing coffee powder for three persons is placed in the filter holder (3) in the middle, and a cup (3 When Cb) is placed below the filter (S39), when the selection button (59b) for three persons is selected and operated (S40), it is judged that the cup is for three cups (S41), After setting the pouring volume to about 500 cc (S48), the opening time of the pouring valve (35) is extended (large) (S49), and the pouring locus in the shape of “NO” is reduced to three persons. After setting to "Large" (S50), the character pouring of "NO" is executed.

This eliminates the need to operate the extraction button as many times as the number of people even when a plurality of people need coffee liquid, and can extract the extraction amount for a plurality of people at once. FIG. 21 and FIG. 22 are schematic views of a system that enables pouring of the filter when the filter is set at a predetermined position, and FIG. 23 is an external view of the main body of the extractor. (60) (60) (60) is a support stand attached to a part of the main body, (61) is a lead switch attached to the support stand, and holder (3) (3) (3) is the support stand (60) ) Has a storage portion (63), (63), (63) which is provided so as to be detachable or slidable and which detachably stores the filter (4). (64) (64) (64) is a magnet attached to a part of the holder (3) (3) (3). The lead switches (61), (61), (61) and the magnets (64), (64), (64) are position detecting means for detecting whether or not the holder is set at a predetermined position on the support base (60). The position detecting means comprises an extraction button when the holder is set at a predetermined position.

The pouring operation according to (65) is executed.

 For example, as shown in FIG. 21, when the holder (3) is set at a predetermined position, the reed switch (61) is closed by the magnet (64) and the operation of the extraction button (65) is stopped. When the holder (3) was not set in place as shown in Fig. 22, the magnet (64) did not reach the vicinity of the reed switch (61) and the lead switch (61) was opened. The pouring operation does not start even if the extraction button (65) is operated.

 As a result, when the filter 1 is neglected to be set at a predetermined position, the hot water is poured into the cup as it is and the coffee cannot be extracted, or when the hot water hits a part of the holder 1 and scatters. Can be prevented.

 FIG. 23 is an external perspective view showing an embodiment of the device main body (1) in which a plurality of people can easily put a cup in and out. The main body consists of a bottom plate (66), a lower body (67), a first side (68), a second side (69), an upper body (70), a lid (71), and the like. ing.

 The upper body (70) is made of, for example, plastic or a metal plate, and is composed of an upper portion, an intermediate portion, a bottom portion (75), and side portions (76). The upper, middle, and bottom portions 15 are all formed in a flat plate shape, and are respectively located at the upper, middle, and lower portions of the upper body (70). The side part (76) is formed so as to be connected to the upper part, the middle part, and the bottom part (75), respectively, and is formed so as to form each side face of each part.

 The lid (71) is formed, for example, in a substantially elliptical shape when viewed from a plane, and in a substantially concave shape when viewed in cross section, and is fixed to the upper surface of the upper body (70). The main body (1) is composed of these parts.

 The first tank is formed in a substantially closed box shape, an opening (not shown) is formed at an appropriate position, and a water inlet (77) is connected to the opening. The water inlet (77) is formed to be openable and closable, and its end is configured to protrude from the lower body (67). The first tank is formed to have a relatively large capacity, for example, a capacity of 10 liters. In this way, the user can fill the first tank with, for example, 10 liters of water by pouring water from a container (not shown, such as a bottle or a kettle) into the water inlet (77). . The first tank is mounted on the bottom plate (66).

 The second heater includes, for example, a hot plate and a heater. For example, a substantially U-shaped heater is embedded in the hot plate when viewed from a plane. The bottom surface of the first tank is formed in a concave shape, and the second heater is fixed to the concave portion.

 The second tank is formed in a substantially closed box shape, and is placed on the upper part of the upper body (70). The second tank is formed to have a relatively small capacity, for example, one liter in capacity. Thus, the capacity of the first tank is configured to be larger than the capacity of the second tank.

The lower body (67) is formed with an upper part (78) and an intermediate part, and the upper part (78) and the intermediate part are formed so as to extend in the horizontal direction and to have an opening in the central part. The base (2) has a concave mounting surface (79) formed in place. The cup (C) that receives the extracted coffee liquid is placed on the mounting surface (79) of the mounting part (80). It is configured as follows. The pouring pipes (7), (7), (7) are both formed in a spiral shape, and one end thereof is configured to face substantially the center of the side opening of the upper body (70) when stationary.

 In such a configuration, a person who extracts coffee and a person who carries coffee can put a cup in and out of each place. Industrial applicability

 It is always poured evenly over a wide range of coffee grounds to extract the optimal coffee liquor with excellent taste and aroma. Especially, such coffee liquor is continuously taken out. By delaying the operation of the rocking mechanism by the delay device, the molten metal is poured for a predetermined time from the opening of the pouring valve, so that the rocking mechanism operates even though the coffee powder is not poured from the pouring port. To prevent

 In the swinging mechanism, in the initial state at the start of pouring, the pouring port is located in the center of the filter, so that the hot water in the pouring port is always poured from the center of the coffee powder, and the regular pouring is performed. Hot water gives the best coffee liquor.

 The pouring pipe is swirled by the first motor and the second motor to pour the powder into the powder while rotating the pouring pipe.Therefore, there is no malfunction or failure without using a complicated link mechanism. Pouring can be performed as if to draw.

 The shaft of the first motor and the shaft of the second motor are arranged so as to be orthogonal to each other, and the pouring pipe is swirled in the X-axis direction by one motor and in the Y-axis direction by the other motor. In this case, the operation of the first motor is accurately conveyed to the second motor and the second motor. The hot water pipe can be turned to the specified position, and the swing in the X-axis direction and the Y-axis direction can be controlled independently, making it possible to change the spiral winding.

The first and second modes are activated by a plurality of predetermined coordinate points. Since the pouring of "no" is performed, when pouring from the pouring pipe, the operating time of one of the motors is changed so that the pouring of "no" is automatically performed at the specified position. The trajectory of the “no” character can be easily enlarged or reduced simply by using it alone.

 The pouring pipe is corrected to the home position at the start of rocking by the position detection device that sets the start position of the first motor and the second motor. Spiral-shaped pouring can be performed from the origin position of the coffee powder, so that a required amount of pre-set pouring can be performed in the required area of the coffee powder, and the hot water penetrates into the inside of the coffee powder to produce a delicious coffee. Extract the arsenic solution.

 The oscillating mechanism starts turning the pouring pipe from the home position facing the center of the filter, and returns to the home position after one or several turning operations.The pouring pipe returns to the home position. Because the origin adjustment means is provided for correction, even if the pouring pipe is not at the correct position due to the variation of the mounting position of the swing mechanism, the pouring pipe is corrected to the correct position by the origin adjusting means, Pour the extract in a wide range evenly with the hot water stored in the filter for rich and flavorful extraction.

 The pouring pipe for pouring coffee powder while oscillating with a rocking device is composed of an upper pipe and a lower pipe, and these pipes are connected by flexible joints. If the erroneously touches the lower pipe, it will not adversely affect the rocking device, and the joint returns the lower pipe to its original position, preventing deformation and displacement of this pipe.

 Since the temperature of the hot water supplied to the hot water tank is maintained at a higher temperature than the temperature of the hot water in the hot water storage tank, the hot water required for extracting the coffee liquid can be taken out immediately when needed. Insufficient hot water in the hot water tank is supplied to the hot water tank from the hot water storage tank that has been heated to a low temperature, so it takes time to heat the hot water to the hot water temperature suitable for extracting coffee liquid in the hot water tank. Be shorter.

Since the outlet at one end is connected above the intake port of the overflow pipe of the water heater tank and the outlet at the other end is connected to the inside of the hot water storage tank, an outlet pipe is connected. Even if the pouring pipe is opened when the intake pipe of the overflow pipe is blocked by waves or waves, the inside of the boiling tank draws air from the outlet pipe to create a negative pressure. Instead, it can extract coffee liquid and the like.

 If the temperature of the hot water in the hot water storage tank is lower than the predetermined temperature, the hot water supply pump is operated to circulate the hot water in the hot water storage tank and the hot water in the hot water tank. Since the operation is stopped, a large amount of hot water can be raised to a temperature suitable for extraction by one heater, and continuous extraction can be performed with minimum power consumption. The system is provided with a pouring volume setting means that changes the pouring volume according to the cup's internal capacity, so that even when multiple people need extract, the operation buttons must be operated as many times as the number of people. And the extraction volume of several people at a time can be taken out at the same time, so that the same hot extract can be served at the same time.

 When the holder is set at the predetermined position, the pouring operation is performed by the operation button.If the holder is not set at the correct position, it will not be possible to extract water, and the hot water will scatter and burn. Also, it prevents the draining of hot water or wasteful water.

 Since the holder has a housing for the filter formed in a part thereof, the filter can be easily set in the holder.

 Since a cavity is formed between the base and the filter so that the forceps can be taken out from the left side or the right side, the cup placed on the lower surface of the cavity can be easily removed from the left or right side. Can be taken out.
