Description

[Technical field]

[0001] The present disclosure relates to pressure cookers. [Background technology]

[0002] A known example of this type of pressure cooker is the pressure cooker described in Patent Document 1. The pressure cooker in Patent Document 1 is equipped with a clamping part that clamps the flange part of the pot and the inner lid, and is configured so that when the inner lid moves upward due to pressure inside the pot, the clamping part comes into contact with the underside of the flange part of the pot and the upper surface of the inner lid to restrict further movement of the inner lid. This configuration makes it possible to prevent pressure inside the pot from being applied to the outer lid, and simplifies the structure of the outer lid. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] (Findings on which this disclosure is based) The present inventors have conducted extensive research to provide a pressure cooker with a smaller clamping portion, and have come to the following findings.

[0010] In the pressure cooker of Patent Document 1, when the inner lid moves upward due to pressure inside the pot, the clamping part is configured to come into contact with the inner lid and receive the pressure inside the pot. The clamping part is made of a metal member having high rigidity to suppress deformation due to pressure. The metal member is usually more expensive than a resin member or the like.

[0011] On the other hand, in the pressure cooker of Patent Document 1, the clamping part is attached with a certain degree of play so that it can move smoothly between the clamping position and the release position. In the pressure cooker of Patent Document 1, if the size of the clamping part is reduced, the play may cause the clamping part to shift from the clamping position and the clamped state of the inner lid and the flange part to be unintentionally released. For this reason, it is difficult to further reduce the size of the clamping part in the configuration of the pressure cooker of Patent Document 1.

[0012] Therefore, the inventors have conducted extensive research and have found that providing a biasing portion that biases the clamping portion from the clamp release position toward the clamping position can suppress rattling and, as a result, make it possible to reduce the size of the clamping portion. Based on this novel finding, the inventors have arrived at the following invention.

[0013] According to a first aspect of the present disclosure, there is provided a housing having an upper opening; A pan having a flange portion and accommodated in the housing through the upper opening; an outer lid movable between a closed position covering the upper opening and an open position spaced apart from the upper opening; An inner lid that is detachably attached to the outer lid and that opens and closes the opening of the pot in conjunction with the opening and closing operation of the outer lid; A pair of clamping parts that are movable between a clamping position that clamps the inner lid and the flange part in a thickness direction and a clamping release position that is spaced apart from the inner lid and the flange part, the pair of clamping parts being provided at positions facing each other across a center part of the inner lid in a plan view seen from the thickness direction; A slide member that is movable relative to the outer lid; a moving mechanism that moves the pair of clamping parts to the clamping position or the clamping release position in conjunction with the movement of the slide member; a biasing portion that biases the pair of clamping portions from the clamp release position toward the clamping position; A pressure cooker comprising:

[0014] According to a second aspect of the present disclosure, at least one of the pair of clamping units includes a first clamping member and a second clamping member that are arranged at an interval from each other, The present invention provides a pressure cooker as described in a first aspect, wherein the moving mechanism includes a connecting member that connects the first clamping member and the second clamping member, and is configured to move the connecting member in conjunction with the movement of the sliding member, thereby moving the first clamping member and the second clamping member to the clamping position or the clamp release position.

[0015] According to a third aspect of the present disclosure, there is provided a pressure cooker as described in the second aspect, wherein the biasing portion includes a first spring member which biases the first clamping member from the clamping release position toward the clamping position, and a second spring member which biases the second clamping member from the clamping release position toward the clamping position.

[0016] According to a fourth aspect of the present disclosure, there is provided a pressure cooker described in any one of the first to third aspects, wherein the biasing portion is configured to bias the clamping portion from the clamping release position toward the clamping position and to bias the clamping portion in the thickness direction from the inner lid toward the flange portion.

[0017] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Note that the present disclosure is not limited to the embodiments. In the drawings, substantially the same components are denoted by the same reference numerals.

[0018] In addition, for ease of explanation, the following uses terms indicating directions such as "up," "down," "front," "rear," and "side," assuming a normal state of use, but this is not meant to limit the state of use of the pressure cooker according to the present disclosure.

[0019] (Embodiment) The overall configuration of a pressure cooker according to an embodiment of the present disclosure will be described with reference to Figures 1 and 2. Figure 1 is a perspective view of the pressure cooker according to an embodiment of the present disclosure. Figure 2 is a cross-sectional view of the pressure cooker of Figure 1. The pressure cooker according to this embodiment is, for example, a pressure rice cooker.

[0020] As shown in Figure 1 or Figure 2, the pressure cooker of this embodiment comprises a housing 1 having an upper opening 1A, a pot 2 contained in the housing 1 through the upper opening 1A, and an outer lid 3 that can open and close the upper opening 1A.

[0021] In this embodiment, housing 1 has a bottomed, cylindrical pot accommodating section 12 recessed inward from upper wall 11. An upper opening of pot accommodating section 12 coincides with upper opening 1A. Pot 2 is detachably accommodated in pot accommodating section 12 through upper opening 1A. Pot 2 has an annular flange portion 21 that protrudes outward from the upper end. The inner surface of pot accommodating section 12 is formed so as to leave a specified gap between it and the outer surface of pot 2. Food to be cooked, such as rice or water, is placed in pot 2.

[0022] A heating section 4 for heating the food to be cooked in the pot 2 is provided inside the housing 1 and on the outer peripheral surface of the pot accommodating section 12. In this embodiment, the heating section 4 is composed of an induction heating coil unit that induction heats the pot 2 via the pot accommodating section 12. The induction heating coil unit includes an inner-bottom heating coil 41 and an outer-bottom heating coil 42. The inner-bottom heating coil 41 is arranged to face the periphery of the center of the bottom of the pot 2 across the pot accommodating section 12. The outer-bottom heating coil 42 is arranged to face a corner portion of the bottom of the pot 2 across the pot accommodating section 12.

[0023] An opening 12A is provided in the center of the bottom of pot accommodating section 12. A pot temperature sensor 5, which is an example of a pot temperature detector for detecting the temperature of pot 2, is provided in opening 12A. Pot temperature sensor 5 is positioned so that it can abut against the bottom of pot 2 accommodated in pot accommodating section 12. In this embodiment, the temperature of the food to be cooked in pot 2 is estimated based on the temperature detected by pot temperature sensor 5.

[0024] A control unit 6 is also provided inside the housing 1. The control unit 6 has a storage unit that stores a plurality of cooking sequences for cooking food. Here, a "cooking sequence" refers to a cooking procedure in which the power supply time, heating temperature, heating time, heating output, etc. are predetermined. Each cooking sequence corresponds to one of a plurality of cooking courses. The control unit 6 controls the drive of the heating unit 4 and executes the cooking process based on the cooking course inputted by the input unit 7 described later and the temperature detected by the pan temperature sensor 5.

[0025] The outer lid 3 is configured to be movable between a closed position (position shown in FIG. 1 and FIG. 2) that covers the upper opening 1A and an open position away from the upper opening 1A. In this embodiment, the outer lid 3 is configured to be movable between the closed position and the open position by rotating around a hinge shaft 3A arranged above the upper wall 11 of the housing 1. The outer lid 3 has a hollow structure. The outer lid 3 is provided with an exhaust hole 31 that penetrates the outer lid 3 in the thickness direction to exhaust steam generated in the pot 2 to the outside. In addition, the outer lid 3 is provided with an operating unit 32 at a position away from the hinge shaft 3A so as to engage with the housing 1. The outer lid 3 is held in the closed position by engaging the housing 1 with the operating unit 32. On the other hand, the outer lid 3 can be moved to the open position by releasing the engagement between the housing 1 and the operating unit 32. In this embodiment, the side where the hinge shaft 3A is provided is referred to as the "rear" and the side where the operating unit 32 is provided is referred to as the "front". An input unit 7 for inputting various information is provided inside the outer lid 3.

[0026] The input unit 7 is provided with a display unit (not shown) such as a liquid crystal display that displays various information such as cooking courses and cooking times, and a selection unit (not shown) that allows a specific cooking course to be selected from a plurality of cooking courses. The selection unit is configured to be able to instruct the start, cancellation, and reservation of cooking, as well as the selection of a cooking course. The user can select a specific cooking course using the selection unit while referring to the contents displayed on the display unit, and instruct the start of cooking. In this embodiment, the input unit 7 is a touch panel type input unit.

[0027] As shown in FIG. 2, an inner lid 8 is removably attached to the outer lid 3. The inner lid 8 is configured to open and close the opening of the pot 2 in conjunction with the opening and closing (rotating) movement of the outer lid 3. That is, the inner lid 8 is removably attached to the surface of the outer lid 3 facing the upper opening of the pot 2 accommodated in the pot accommodation section 12. When the outer lid 3 is in the closed position, the inner lid 8 is configured to cover the upper opening of the pot 2. An annular gasket 81 is attached to the outer peripheral surface of the inner lid 8 facing the pot 2. The gasket 81 is configured to fit closely to the vicinity of the flange portion 21 of the pot 2 to seal the gap between the pot 2 and the inner lid 8 when the outer lid 3 is in the closed position.

[0028] The outer lid 3 is provided with a slide member 33 that is movable relative to the outer lid 3. FIGS. 3A to 3C show the manner in which the slide member 33 moves relative to the outer lid 3. FIGS. 4A to 4C and 5A to 5B show the various parts and mechanisms that move in conjunction with the relative movement of the slide member 33 with respect to the outer lid 3. In this embodiment, the slide member 33 is made of a substantially T-shaped plate-like member and has an opening 33A at the center. The power transmission member 37 is attached to the slide member 33 by inserting a convex portion 37A of the power transmission member 37 into the opening 33A. A gear (not shown) is provided on the back surface (opposite side of the convex portion 37A) of the power transmission member 37. The gear is provided to mesh with a gear (not shown) of the motor 38. When the motor 38 is driven by the control unit 6, the slide member 33 receives the driving force of the motor 38 via the power transmission member 37 and is configured to move relative to the outer lid 3 in the front-to-rear direction X1 (the left-to-right direction in Figures 4A to 4C).

[0029] The outer lid 3 is provided with a pair of clamping parts 34, 34, a moving mechanism 35, and a biasing part .

[0030] The pair of clamping portions 34, 34 are configured to be movable between a clamping position (position shown in FIG. 5B) where they clamp the inner lid 8 and the flange portion 21 of the pot 2 in the thickness direction, and a released position (position shown in FIG. 5A) where they are spaced apart from the inner lid 8 and the flange portion 21 of the pot 2. The pair of clamping portions 34, 34 are provided in positions facing each other across the center of the inner lid 8 when viewed from the thickness direction (see FIGS. 4A to 4C). In this embodiment, the center of the inner lid 8 coincides with the center 3a of the outer lid 3 and the center of the pot 2 when viewed from the thickness direction. In this embodiment, the pair of clamping portions 34, 34 are configured to be line-symmetrical with respect to a virtual straight line L1 that passes through the center 3a of the outer lid 3 in the front-to-rear direction X1 when viewed from the thickness direction.

[0031] Each clamping section 34 includes a first clamping member 341 and a second clamping member 342 arranged at a distance from each other. The first clamping member 341 and the second clamping member 342 each have a substantially U-shaped cross section so as to sandwich the inner lid 8 and the flange portion 21 of the pot 2 in the thickness direction.

[0032] The moving mechanism 35 is configured to move the pair of clamping parts 34, 34 to a clamping position (position shown in FIG. 5B) or a clamping release position (position shown in FIG. 5A) in conjunction with the movement of the slide member 33. Specifically, the moving mechanism 35 is configured to move the pair of clamping parts 34, 34 from the clamping release position to the clamping position when the slide member 33 is moved in one direction (from rear to front) from the position shown in FIG. 3A to the position shown in FIG. 3C. Conversely, the moving mechanism 35 is configured to move the pair of clamping parts 34, 34 from the clamping position to the clamping release position when the slide member 33 is moved in the opposite direction (from front to rear) from the position shown in FIG. 3C to the position shown in FIG. 3A.

[0033] In this embodiment, the moving mechanism 35 includes a connecting member 351 that connects the first clamping member 341 and the second clamping member 342. The moving mechanism 35 is configured to move the connecting member 351 in conjunction with the movement of the slide member 33, thereby moving the first clamping member 341 and the second clamping member 342 to the clamping position (position shown in FIG. 5B) or the clamp release position (position shown in FIG. 5A). In this embodiment, the connecting member 351 is integrally formed of the same metal material as the first clamping member 341 and the second clamping member 342. Note that the connecting member 351 may be formed separately from the first clamping member 341 and the second clamping member 342 by using a different metal material.

[0034] In this embodiment, the moving mechanism 35 includes a pair of cam plates 352, 352 connected to the slide member 33. In this embodiment, the pair of cam plates 352, 352 are configured to be symmetrical with respect to the virtual straight line L1 in a plan view. Each cam plate 352 is provided with a cam groove 352A. The cam groove 352A has an inclined surface 352Aa inclined with respect to the front-rear direction X1 and the lateral direction Y1 perpendicular to the front-rear direction X1. The inclined surface 352Aa provided on one cam plate 352 and the inclined surface 352Aa provided on the other cam plate 352 are inclined in a direction away from each other as they approach the operation unit 32 in a plan view.

[0035] Each connecting member 351 has a cam pin 351A that engages with the cam groove 352A. When the motor 38 is driven by the control unit 6, the gear of the motor 38 and the gear of the power transmission member 37 mesh with each other, and the power transmission member 37 moves in the front-rear direction X1 relative to the outer lid 3. As a result, the slide member 33, in which the convex portion 37A of the power transmission member 37 is inserted into the opening 33A, moves in the front-rear direction X1 relative to the outer lid 3. When the slide member 33 moves in the front-rear direction X1, each cam pin 351A slides along the inclined surface 352Aa of the corresponding cam groove 352A. As a result, when each connecting member 351 moves toward the virtual straight line L1, the pair of clamping portions 34, 34 move closer to each other. When each connecting member 351 moves away from the virtual straight line L1, the pair of clamping portions 34, 34 move away from each other. As a result, as shown in Figures 3A to 3C and 4A to 4C, the pair of clamping parts 34, 34 move between the clamping position (position shown in Figure 5B) and the clamping release position (position shown in Figure 5A). The pair of clamping parts 34, 34 are biased by the biasing part 36 from the clamping release position toward the clamping position.

[0036] 4A to 4C, the biasing section 36 includes a first spring member 361 that biases the first clamping member 341 from the clamp release position toward the clamping position, and a second spring member 362 that biases the second clamping member 342 from the clamp release position toward the clamping position. In the present embodiment, the first spring member 361 and the second spring member 362 are formed of thread springs.

[0037] One end of first spring member 361 is fixed to outer lid 3, and the other end is provided to engage with hook portion 341A provided on first clamping member 341. In a plan view, first spring member 361 biases hook portion 341A toward L1, thereby biasing first clamping member 341 from the clamping release position toward the clamping position. In this embodiment, first spring member 361 is configured to bias first clamping member 341 in the thickness direction from inner lid 8 toward flange portion 21 of pot 2.

[0038] One end of the second spring member 362 is fixed to the outer lid 3, and the other end is provided to engage with a hook portion 342A provided on the second clamping member 342. In a plan view, the second spring member 362 biases the hook portion 342A toward L1, thereby biasing the second clamping member 342 from the clamping release position toward the clamping position. In this embodiment, the second spring member 362 is configured to bias the second clamping member 342 in the thickness direction from the inner lid 8 toward the flange portion 21 of the pot 2.

[0039] According to this embodiment, since the biasing portion 36 that biases the clamping portion 34 from the clamping release position toward the clamping position is provided, it is possible to suppress rattling of the clamping portion 34. This makes it possible to suppress the clamping portion 34 from shifting from the clamping position and unintentionally releasing the clamped state of the inner lid 8 and the flange portion 21. As a result, the size of the clamping portion 34 can be made smaller than in the past.

[0040] According to this embodiment, each clamping unit 34 includes a first clamping member 341 and a second clamping member 342 that are spaced apart from each other. The moving mechanism 35 includes a connecting member 351 that connects the first clamping member 341 and the second clamping member 342. The moving mechanism 35 is configured to move the connecting member 351 in conjunction with the movement of the slide member 33, thereby moving the first clamping member 341 and the second clamping member 342 to the clamping position or the clamp release position. As a result, there is no clamping unit between the first clamping member 341 and the second clamping member 342, so that the size of the clamping unit 34 can be further reduced.

[0041] According to this embodiment, the biasing portion 36 includes a first spring member 361 that biases the first clamping member 341 from the clamping release position toward the clamping position, and a second spring member 362 that biases the second clamping member 342 from the clamping release position toward the clamping position. This allows appropriate biasing forces to be applied to the first clamping member 341 and the second clamping member 342, respectively, and can further reduce rattling of each clamping portion 34. As a result, it is possible to prevent the clamping portion 34 from shifting from the clamping position and unintentionally releasing the clamped state of the inner lid 8 and the flange portion 21, and the size of the clamping portion 34 can be further reduced.

[0042] Furthermore, according to this embodiment, the biasing portion 36 is configured to bias the clamping portion 34 in the thickness direction from the inner lid 8 toward the flange portion 21 of the pot 2. This can also suppress wobbling of the clamping portion 34 in the thickness direction. As a result, it is possible to prevent the clamping portion 34 from shifting from the clamping position and unintentionally releasing the clamped state between the inner lid 8 and the flange portion 21, and the size of the clamping portion 34 can be further reduced.

[0043] Furthermore, according to this embodiment, the first clamping member 341 and the second clamping member 342 are configured to be pivotally supported at one point by the cam pin 351A provided on the connecting member 352. This reduces the number of pivotally supported members, making it possible to make the device more compact, but since the first clamping member 341 and the second clamping member 342 have open ends, rattling in the rotational direction is likely to occur. In this case, the configuration of this embodiment, which includes the biasing portion 36 that biases the clamping portion 34 from the clamp release position toward the clamping position, is particularly effective because rattling in the rotational direction can be suppressed.

[0044] Also, according to this embodiment, the sliding member 33 is configured to move in the front-rear direction X1 by the driving force of the motor 38. Since the driving force of the motor 38 is usually weaker than that of manual operation, if the clamping portion 34 is intentionally made loose to widen the range of motion, the clamping portion 34 will be able to clamp the pot 2 more easily. On the other hand, if the looseness of the clamping portion 34 becomes excessively large, the clamping portion 34 may not be able to properly clamp the pot 2. In this case, the configuration of this embodiment, which includes the biasing portion 36 that biases the clamping portion 34 from the clamping release position toward the clamping position, is particularly effective because it can suppress excessive looseness while widening the range of motion of the clamping portion 34.

[0045] The present disclosure is not limited to the above embodiment, and can be embodied in various other forms. For example, in the above, both of the pair of clamping units 34 are configured with the first clamping member 341 and the second clamping member 342, but the present disclosure is not limited to this. For example, only one of the pair of clamping units 34 may be configured with the first clamping member 341 and the second clamping member 342.

[0046] In the above description, the first pinching member 341 is provided with the first spring member 361 for biasing the first pinching member 341 from the clamp release position toward the pinching position, and the second spring member 362 for biasing the second pinching member 342 from the clamp release position toward the pinching position, but the present disclosure is not limited to this. For example, a single arc-shaped spring member may be provided to bias both the first pinching member 341 and the second pinching member 342 from the clamp release position toward the pinching position. This configuration reduces the number of components and improves ease of handling. However, this configuration requires a larger space to provide the spring member.

[0047] In the above description, the first spring member 361 and the second spring member 362 are configured as string springs, but the present disclosure is not limited to this. For example, the first spring member 361 and the second spring member 362 may be configured as leaf springs or coil springs.

[0048] Although the present disclosure has been fully described in connection with the preferred embodiments with reference to the accompanying drawings, various changes and modifications will be apparent to those skilled in the art, and such changes and modifications should be understood to be included within the scope of the present disclosure as defined by the appended claims unless they depart therefrom. [Industrial Applicability]

[0049] Since the pressure cooker according to the present disclosure can reduce the size of the clamping portion, it is useful, for example, as a pressure rice cooker. [Explanation of symbols]
