Description

  The present invention relates to an electric pot.

  Generally, an electric pot has a structure in which an inner container for boiling water is housed in an outer container. The outer container has a shoulder that closes between the upper part of the inner container and closes with the outer lid. Various devices such as a power supply circuit, a control board, a pump, and piping are incorporated in an internal space formed between the outer container and the inner container. Operation buttons for performing various function settings, power operations, and the like are exposed on the shoulder of the outer container. In addition, a substrate storage chamber is provided on the shoulder, inside the operation button, for storing an operation substrate to which an operation switch is attached. The other end of the lead wire connected to the operation board passes from the board storage chamber to the inside of the outer container and is connected to the control board and the like.

  The electric pot is designed not to be submerged inside the outer container, but may be washed in a very rare manner. At the time of this round washing, water may be immersed in the outer container, and water droplets may adhere to the lead wires. The water droplets adhering to the lead wire travel along the lead wire toward the substrate storage chamber when the electric pot is turned upside down. In order to prevent such water droplets from entering the substrate storage chamber, a packing for closing the space between the lead wire and the inner periphery of the extraction port has conventionally been provided at the lead wire outlet formed in the substrate storage chamber. (See Patent Document 1).

JP-A-8-10164 (FIG. 5, paragraphs 0024, 0025, 0028)

  Regardless of whether or not packing is provided at the take-out port as in the conventional example, from the viewpoint of waterproofing the substrate storage chamber, it is preferable to make it difficult for water droplets that have traveled the lead wire to reach the take-out port of the substrate storage chamber. . For example, even if packing is provided at the take-out port of the substrate storage chamber, the shape error and mounting error of the packing, and further, a decrease in elasticity due to secular change cannot be avoided.

  Accordingly, an object of the present invention is to provide an electric pot provided with a substrate storage chamber for storing an operation substrate with an operation switch attached to the shoulder of the outer container, with a lead wire passed from the substrate storage chamber to the inside of the outer container. This is to make it difficult for the water droplets to travel to the lead wire outlet of the substrate storage chamber.

  In order to solve the above-described problems, the present invention has an inner container accommodated in an outer container, the outer container having a shoulder that closes between the upper part of the inner container and closes to the outer lid, A substrate storage chamber for storing an operation substrate to which an operation switch is attached; and an electric pot in which a lead wire connected to the operation substrate is passed from the substrate storage chamber to the inside of the outer container. Forming a lead-out port for lowering the lead wire, and having a lid member covering the outside of the substrate storage chamber at the lead-out port, and taking out the lead wire lowered between the lid member and the lead-out port outside the lead-out port It is characterized by a configuration provided with a labyrinth to be raised.

According to the configuration of the present invention, since the lid member covers the take-out port from the outside of the substrate storage chamber, water droplets do not enter the room directly from below the take-out port in an upside down state. If a lid member covering the take-out port from the outside of the substrate storage chamber is used, a labyrinth through which the lead wire can pass can be provided between the take-out port.
The labyrinth is upside down and generates a lift that raises the lead wire with respect to the take-out port outside the take-out port, so that water droplets traveling along the lead wire are difficult to go to the take-out port.

  Specifically, a configuration is adopted in which a discharge conduit that leads to the inner container is arranged below the substrate storage chamber, and the valve case of the overturn stop water valve that constitutes the discharge conduit is used as the lid member. Thus, the number of assembled parts can be reduced.

Further, in the specification, when the valve case and the lid member are provided separately, the lid member is a standing wall portion that forms the labyrinth between the spigot portion fitted to the take-out port and the take-out port. The discharge pipe line leading to the inner container is disposed below the substrate storage chamber, and a valve case of a tip-off water valve constituting the discharge pipe is provided at the take-out port. A configuration in which the fitted lid member is pressed so as not to fall can be employed.
According to this configuration, the lid member is positioned in the horizontal direction with respect to the take-out port by the fitting of the inlay portion, and the valve case is pressed so as not to fall from the take-out port. The engaging portion is not necessary, and the lid member can be downsized.

  By adopting a configuration in which the labyrinth is formed as a passage in which a water film is not formed by capillary action, it is possible to prevent water droplets traveling along the lead wire from forming a water film in the labyrinth and reaching the extraction port.

  Bending the water-impermeable flat seal member and sandwiching the lead wire, pushing the flat seal member sandwiching the lead wire into the take-out port, the flat seal member pushed into the take-out port is restored by elastic recovery. If the structure attached to the inner periphery of the lead wire and the outlet is employed, the outlet can be easily sealed simply by sandwiching and pushing the lead wire with a flat seal member. Further, the flat seal member can be easily formed by appropriately cutting from a flat packing material, and can be manufactured at a lower cost than a ring-shaped seal member.

  As described above, according to the present invention, in the electric pot provided with the substrate storage chamber for storing the operation substrate to which the operation switch is attached on the shoulder of the outer container, the substrate storage chamber is adopted by adopting the above characteristic configuration. Thus, it is possible to make it difficult for water droplets traveling along the lead wire passed through the inside of the outer container to go to the lead wire outlet of the substrate storage chamber.

Hereinafter, an electric pot according to a first embodiment of the present invention will be described with reference to the accompanying drawings.
FIG. 1 shows the overall configuration of the electric pot according to the first embodiment in a longitudinal section.
As shown in FIG. 1, the electric pot according to the first embodiment is obtained by storing an inner container 1 in an outer container 2. The outer container 2 includes a shoulder 3 that closes between the upper part of the inner container 1, a body 4 that is integrated with the shoulder 3, an outer lid 5 that closes with the shoulder 3, and an upper front surface of the shoulder 3. It has a panel 6 attached, a bottom 7 incorporated in the bottom opening of the body 4, and a liquid level display panel 8 attached to the front of the body 4.

FIG. 2 shows an appearance of the left side surface of the electric pot according to the first embodiment. FIG. 3 shows an exploded perspective view of the front part of the shoulder 3.
As shown in FIGS. 1 to 3, the front portion of the outer container 2 has a beak shape with a shoulder 3, a body 4, and a panel 6, and a discharge port 9 faces the outside from the front lower plate. From the panel 6, the operation unit 10 is exposed to the outside. The bottom part 7 functions as a turntable.

  The shoulder 3 is composed of an integrally molded product of synthetic resin, and has an inner peripheral lower portion 31 that closes the upper portion of the inner container 1 and an inner peripheral upper portion 32 that closes the outer lid 5. A substrate storage chamber 40 for storing the operation substrate 20 to which the operation switch 21 is attached is provided in a portion of the shoulder 3 constituting the front portion of the outer container 2.

  A heater 11 that heats the inner container 1, a water feed pump 12, a pumping pipe 13, and an overturn stop valve 14 are incorporated in the inner space between the shoulder 3 and the body 4. The fall stop water valve 14 is a valve that automatically stops water when the electric pot falls, and a conventionally well-known configuration is adopted. This overturning water stop valve 14 is configured to serve as a discharge pipe that connects between the pumping pipe 13 and the discharge port 9, and is disposed below the substrate storage chamber 40 in the front portion of the outer container 2. .

  A through-hole 15 for opening the discharge port 9 to the outside is opened in a portion of the body 4 constituting the front lower plate of the outer container 2. Water blocking ribs 16 are provided on the inner wall of the barrel 4 so as to prevent water from the through holes 15 from flowing down to the inner container 1 side. Thereby, the charging part built in the bottom part vicinity, such as the heater 11 and the water pump 12, is protected.

  FIG. 4A shows the front left side surface of the shoulder 3 in an enlarged manner. As shown in FIG. 2 and FIG. 4A, the upper outer peripheral wall 33 of the shoulder 3 is a portion that abuts the body 4 vertically. With the design that the front upper surface of the outer container 2 descends as it advances toward the front end side, the front end portion of the upper outer peripheral wall 33 of the shoulder 3 is a wall whose upper portion swells outside the lower portion. The front end portion of the upper outer peripheral wall 33 is undercut in a hatched portion UC indicated by a one-dot chain line in FIG. 4A when the mold is released above and below the shoulder 3. Therefore, the mold part line PL1 of the shoulder 3 is set so as to pass through the front end upper edge P1 of the front end portion of the upper outer peripheral wall 33 so that the hatched portion UC is not undercut.

  In particular, the mold part line PL1 is set so as to gradually approach the horizontal as it advances from the front end upper edge P1 to the rear side, and to connect to the continuous part P2 with the rear lower edge of the upper outer peripheral wall 33. When the mold part line PL1 is gradually changed as shown in FIG. 4A, the line is not easily noticeable. When the mold part line is passed through the upper edge of the rear part of the upper outer peripheral wall 33, there is a concern that, when a flash occurs, the touch is likely to be deteriorated only in the part that is easy to touch, and the water is likely to be scattered due to the flash when thrown away. However, if it passes through the lower rear edge of the upper outer peripheral wall 33, there is no such concern.

  FIG. 4B shows another example of the mold part line PL2. As shown in FIGS. 2 and 4B, the mold part line PL2 is passed along the upper edge of the upper outer peripheral wall 33 from the front upper edge P1 of the front end portion of the upper outer peripheral wall 33 along the upper edge. It passes along the extension of the outer shape line from above P3 that intersects with the extension of the outer shape line of the front end wall of the upper part 32, and from P4 that intersects with the lower rear edge of the upper outer peripheral wall 33 to the rear lower edge of the upper outer peripheral wall 33 It can also be set to connect. When the mold part line PL2 is passed as shown in FIG. 4B, visual integrity with the outer shape line of the front end wall of the inner peripheral upper portion 32 is increased, and the appearance is less noticeable.

  As shown in FIG. 1, the outer lid 5 has a steam port 50 communicating with the inner container 1. The steam port 50 is provided so as to cover the outlet of the tipping water stop valve incorporated in the outer lid 5. As shown in FIGS. 5 (a) to 5 (c), the steam port 50 has a structure in which a plurality of outlets 51 are formed in a concentric arc shape, and each outlet 51 is connected to the same inlet 52. Yes. Between each outlet 51 and the inlet 52, an inverted semi-cylindrical wall 53 is provided so as not to communicate vertically from the inlet 52 to each outlet 51. In this way, when the boiling operation is performed in a state where condensation occurs in the inner periphery of the inlet 52 and the overturn stop water valve, and when the steam starts to blow up, the dew condensation that has been blown off is in the shape of each inverted half bowl. Since it is caught by the wall 53, it becomes difficult to blow out from each outlet 51 to the outside.

  FIG. 6 shows an enlarged view of the substrate storage chamber 40 of FIG. FIG. 7 shows an exploded perspective view of the operation board 20. FIG. 8 shows an exploded perspective view of the operation unit 10 from the inner surface side of the panel 6. As shown in FIGS. 3 and 6, the substrate storage chamber 40 is provided with an open top at a side periphery 41 a and a bottom plate 41 b. The operation substrate 20 is attached to the inside of the substrate storage chamber 40 from above the shoulder 3. In the substrate storage chamber 40, an outlet 41c for the lead wire L connected to the operation substrate 20 is formed so as to protrude downward from the bottom plate 41b. Although all or part of the bottom plate 41b of the substrate storage chamber 40 can be separated as in the above-mentioned Patent Document 1, the shoulder 3 and the bottom plate 41b are integrally formed as in the first embodiment. Then, the opening of the take-out port 41c can be made smaller than the operation substrate 20, and there is an advantage that the sealing surface is relatively reduced.

  As shown in FIG. 7, in addition to the operation switch 21, display light emitting elements D are also attached to a plurality of locations on the upper surface of the operation substrate 20. A tact switch is used as the operation switch 21 and a diode is used as the light emitting element D. The operation unit of the operation switch 21 faces a plurality of operation buttons 10 a constituting the operation unit 10.

  As shown in FIG. 8, the operation unit 10 is composed of a synthetic resin molded product in which each of the plurality of buttons 10a is provided integrally with the support frame 10c via the arm unit 10b.

  As shown in FIGS. 6 and 7, a switch spacer 22 for transmitting a button operation between the operation buttons 10 a and the operation switch 21 is integrated with the operation board 20.

  The switch spacer 22 is a composite in which a spacer portion 22a and a mounting plate portion 22b are integrally provided via a support arm portion 22c, and a mounting plate portion 22b and a claw leg portion 22d extending downward therefrom are integrally provided. It consists of a molded product of resin. By making the plurality of buttons 10a and the plurality of spacer portions 22a into integral parts, assembly is facilitated.

  As shown in FIGS. 3 and 6, the switch spacer 22 and the operation substrate 20 are integrated so that they can be attached to the substrate storage chamber 40 at the same time. That is, when the front end of the operation substrate 20 integrated with the switch spacer 22 is placed on the support rib 41 d that protrudes into the substrate storage chamber 40, it is then placed on the screw hole 41 e that protrudes into the substrate storage chamber 40. The operation board 20 and the like are positioned at the side periphery 41a and are screwed from the back side of the shoulder 3 at the screw hole portion 41e.

  The operation unit 10 and the switch spacer 22 are adapted to transmit button operations via a single waterproof sheet 23 that covers the substrate storage chamber 40 from above. The waterproof sheet 23 is bonded to the shoulder 3 and the mounting plate portion 22b. By the adhesion of the waterproof sheet 23, water that has passed through the button holes of the panel 6 is prevented from entering the substrate storage chamber 40.

As shown in FIG. 8, the operation unit 10 takes a position corresponding to each button 10 a and each button hole 6 b of the panel 6, and projects a fitting hole 10 d formed in the operation unit 10 from the inner surface side of the panel 6. The panel 6 can be temporarily fixed by being press-fitted into the rod-shaped portion 6a.
Here, the synthetic | combination which integrally provided between the operation part 10 and the panel 6 the translucent cap part 24a which covers each light emitting element D from upper direction, and the support frame 24b with which each cap part 24a was provided in a row. The light emitting element protection member 24 made of a resin molded product is also temporarily fixed.
The light-emitting element protection member 24 takes a position corresponding to each cap portion 24 a and each exposure hole 6 c of the panel 6, and the support frame 24 b of the light-emitting element protection member 24 is formed in a positioning recess 6 d formed inside the panel 6. When inserted, the movement on the panel 6 is prevented. As shown in FIG. 9, the light emitting element protection member 24 and the operation unit 10 are temporarily fixed simultaneously by temporarily fixing the operation unit 10 on the light emitting element protection member 24 so as to overlap the panel 6. In this state, as shown in FIG. 6, when the panel 6 and the shoulder 3 are integrated, the light emitting element protection member 24 and the operation unit 10 are sandwiched between the shoulder 3 and the panel 6 so that the temporary fixing is not removed. It has become.

  As shown in FIGS. 8 and 9, light shielding ribs 6e are provided on the inner surface side of the panel 6 to prevent light from a certain light emitting element D from reaching other button holes 6b and exposure holes 6c. . As a result, erroneous recognition of the lighting display is prevented.

  The panel 6 and the shoulder 3 are integrated by pushing the claw portion 6f protruding from the front portion on the inner surface side of the panel 6 into the claw engaging portion 34 of the shoulder 3 shown in FIG. As shown in FIGS. 8 and 9, the screw hole portion 6 g protruding from the rear portion on the inner surface side of the panel 6 is screwed from below the shoulder 3.

  Further, as shown in FIG. 10 as a modification of the first embodiment, it is also preferable to provide a waterproof member 25 between the mounting plate portion 22 b of the switch spacer 22 and the shoulder 3 so as to surround the substrate storage chamber 40. If a sufficient bonding area between the waterproof sheet 23 and the shoulder 3 cannot be obtained, the outer edge portion of the waterproof sheet 23 is likely to be lifted. Even in such a case, water is immersed between the outer edge portion of the waterproof sheet 23 and the shoulder 3. Can be prevented from reaching the substrate storage chamber 40 by the waterproof member 25. As the waterproof member 25, for example, a silicon-coated member, silicon rubber, foamed silicon, or the like can be used.

FIG. 11A shows a perspective view of the inside of the front part with the shoulder 3 upside down. FIG.11 (b) has shown the vertical front view containing the opening center of the extraction port 41c in the attitude | position of Fig.11 (a).
As shown in FIG. 11, the take-out port 41c of the substrate storage chamber 40 is formed so as to protrude downward from the bottom plate 41b, so that the lead wire L can be lowered. A part of the outlet 41c has a notch shape that is one step lower, from which a plurality of lead wires L can be taken out side by side.

  The electric pot according to the first embodiment has a lid member 42 that covers the take-out port 41 c from the outside of the substrate storage chamber 40. The lid member 42 is made of a synthetic resin injection-molded product, and the lid member 42 itself does not allow water to pass therethrough.

A labyrinth is provided between the lid member 42 and the take-out port 41c so that the lowered lead wire L is taken out from the take-out port 41c to the side and raised outside the substrate storage chamber 40.
More specifically, as shown in FIG. 12, the lid member 42 is formed in series with the inner and outer double inlay portions 42a and 42b fitted into the take-out port 41c and the outer inlay portion 42b. On the top surface. The lead wire L that protrudes laterally from the take-out port 41c rises from the cut in the inner spigot portion 42a and exceeds the upper portion of the standing wall portion 42c. That is, the lid member 42 has an annular wall including an outer spigot part 42b and a standing wall part 42c that forms a labyrinth between the take-out port 41c.

  Here, the standing wall portion 42c is formed one step lower than the outer spigot portion 42b, and forms a labyrinth with the cutout portion of the take-out port 41c. Thereby, the several lead wire L is put together so that it may not be separated by the level | step difference of the outer spigot part 42b and the taking-out opening 41c.

  As shown in FIGS. 12A to 12C, the lid member 42 has screwing portions 42d extending from both end portions of the outer spigot portion 42b. As shown in FIG. 11B, the lid member 42 is fastened to the lower end of the shoulder 3 with a screw (not shown) passed through the screwing portion 42d, and is fixed thereby.

  With the lid member 42 fixed to the shoulder 3, the labyrinth formed by the take-out port 41c and the standing wall portion 42c is a passage in which a water film is not formed by capillary action. When the standing wall portion 42c and the take-out port 41c are formed of a synthetic resin for general injection molding such as polypropylene, it is possible to prevent capillary action between the inner wall surfaces of the labyrinth if the labyrinth interval l is at least 2 mm. .

In the electric pot according to the first embodiment having the above-described configuration, the lid member 42 is fitted to the take-out port 41c from the outside and the lower side of the substrate storage chamber 40 in the inner and outer double inlay portions 42a and 42b. Since the member 42 covers the outlet 41c, water droplets do not enter the room directly from below the outlet 41c in an upside down state.
The labyrinth formed by the take-out port 41c and the standing wall portion 42c of the lid member 42 causes a lift for raising the lead wire L outside the take-out port 41c in an upside down state. Due to this lift, the water droplets W that travel along the lead wire L are unlikely to go to the outlet 41c.
The water droplets W transmitted through the lead wire L may fall from the lead wire L due to the above-mentioned head. The dropped water droplet W may descend in the labyrinth when returned to the normal vertical position, but the take-out port 41c lowers the lead wire L, that is, raises the head in the normal vertical position. Therefore, even if it descends in the labyrinth, it is difficult to enter the substrate storage chamber 40 from the take-out port 41c. The lead wire is led to the lower side of the inner container 1.

Hereinafter, a second embodiment of the present invention will be described with reference to FIG. In the following description, differences from the first embodiment will be mainly described.
As shown in FIG. 13, the overturn stop water valve 14 ′ is integrally provided with portions 42 a ′ to 42 c ′ corresponding to the inner and outer double inlay portions 42 a and 42 b and the standing wall portion 42 c on the upper surface of the valve case. It has become a thing.
Thus, if the valve case of the overturning water stop valve 14 ′ disposed below the substrate storage chamber 40 is used as a lid member, the number of assembly parts can be reduced. Needless to say, the valve case of the overturn stop valve 14 ′ is sufficiently positioned with respect to the shoulder 3.

  In general, the valve case of the overturn stop valve is configured to be divided into upper and lower parts. For this reason, the upper member of the valve case of the overturning water stop valve and the spigot part are injection-molded integrally, or the inlay part etc. is integrated with the upper surface of the upper member by friction welding, so that the overturn stop water valve The valve case can be a lid member having an inlay portion or the like.

A third embodiment of the present invention will be described with reference to FIG.
As shown in FIG. 14, the lid member 42 ′ according to the third embodiment includes an inlay portion 42 a and 42 b fitted into the take-out port 41 c and a standing wall portion 42 c that forms a labyrinth between the take-out port 41 c. However, the screwing portion 42d shown in FIG. 12 is omitted.
As shown in FIG. 14, the lid member 42 'is positioned in the horizontal direction with respect to the take-out port 41c by fitting the spigot portions 42a, 42b and the take-out port 41c from below the take-out port 41c. In this fitted state, the lower end of the lid member 42 ′ is pressed so as not to fall from the take-out port 41 c at the upper end of the valve case of the overturn stop water valve 14 disposed below the substrate storage chamber 40. For this reason, the screw member and the engaging portion in the vertical direction are not necessary for the lid member 42 ', and the lid member can be downsized.

A fourth embodiment of the present invention will be described with reference to FIG.
As shown in FIG. 15, the lid member 60 according to the fourth embodiment is configured to be covered from outside the substrate storage chamber by sliding from one side with respect to the extraction port 41 c protruding in a rectangular tube shape. The lid member 60 has both side walls 61 and 62 along both long sides of the take-out port 41c, and an end between the both side walls 61 and 62 is an open end for enabling sliding. Although not shown, a standing wall portion corresponding to the standing wall portion 42c is formed so as to connect the left and right other ends between the both side walls 61 and 62. A through hole 63 for obtaining a slide space for the lid member 60 is formed in the shoulder 3.
The flange portion 64 protruding to the inner surface side of the lid member 60 is in a positional relationship passing through the notch-like portion 65 of the extraction port 41c when sliding, and is one longitudinal side of the extraction port 41c at the slide completion position where the labyrinth is formed. The lid member 60 is prevented from dropping by engaging vertically with the flange 66 formed on the side. For this reason, screwing of the lid member 60 is unnecessary.

A fifth embodiment of the present invention will be described with reference to FIG.
As shown in FIG. 16, the electric pot according to the fifth embodiment has a flat plate shape in which a plurality of lead wires L are sandwiched by bending a water-impermeable flat seal member 70 and the plurality of lead wires L are sandwiched therebetween. The seal member 70 is pushed into the take-out port 41c, and the flat seal member 70 pushed into the take-out port 41c is attached to the inner periphery of the lead wire L and the take-out port 41c by elastic recovery.

  As the flat seal member 70, for example, urethane foam, flat silicon, or the like can be used.

  The flat seal member 70 is a rectangular plate having a uniform thickness. When a plurality of lead wires L are sandwiched between the longitudinal sides of the flat seal member 70, the flat seal member 70 substantially coincides with the inner periphery of the extraction port 41c protruding into a rectangular cylinder. Also, a compression margin is formed with respect to the inner periphery of the take-out port 41c. Thereby, the flat seal member 70 can take out the plurality of sandwiched lead wires L into the take-out port 41c and push them well. The pressed flat plate-like seal member 70 is attached to the periphery of the plurality of inserted lead wires L in the vicinity of the center by the elastic recovery accompanying the compression allowance, and also to the inner periphery of the take-out port 41c. For this reason, even if a water droplet that has traveled through the lead wire L reaches the take-out port 41c, it is difficult to pass through the take-out port 41c.

  The configuration related to the flat plate-like seal member 70 can be applied regardless of the configuration of the takeout port according to the present invention and whether or not the takeout port is covered with a lid member. The present invention can also be applied to a takeout port having a conventional configuration such as 1.
