Description

[Technical field]

[0001] The present invention relates to a cooking device having a rice cooking function. [Background technology]

[0002] A known conventional cooking device is one equipped with a steam cylinder for discharging steam generated in a pot to the outside of the cooking device (see, for example, Patent Document 1). The steam cylinder is configured to provide fluid communication between the inside of the pot and the outside of the cooking device. For this reason, high-temperature sticky rice (viscous broth) generated during the rice cooking process enters the steam cylinder. If the high-temperature sticky rice is discharged to the outside of the cooking device, it may cause burns. In addition, sticky rice contains a lot of umami components, so the taste of the rice can be improved by returning it to the pot. For this reason, the steam cylinder has a space (hereinafter also referred to as a sticky rice storage section) for storing sticky rice when there is high pressure inside the pot, and is configured to return the sticky rice to the pot when the pressure inside the pot drops.

[0019] In addition, for ease of explanation, in the following, terms indicating directions such as "upper," "lower," "side," "bottom," "front," and "rear" are used assuming a state during normal use, but this is not meant to limit the state of use of the cooking device according to the present disclosure.

[0020] (Embodiment) The overall configuration of a cooking device according to an embodiment of the present disclosure will be described with reference to Fig. 1 and Fig. 2. Fig. 1 is a perspective view of a cooking device according to an embodiment of the present disclosure, seen obliquely from above and in front. Fig. 2 is a cross-sectional view of the cooking device in Fig. 1. The cooking device according to this embodiment is a cooking device having a rice cooking function. In this embodiment, the cooking device is a rice cooker.

[0021] As shown in Figs. 1 and 2, the cooking device according to this embodiment includes a cylindrical cooking device body 1 with a bottom, and a lid 2 that covers an upper opening of the cooking device body 1 in an openable and closable manner.

[0022] As shown in Fig. 2, a bottomed, cylindrical pot storage section 11 for detachably storing pot 3 is formed inside cooker body 1. Pot storage section 11 is composed of a protective frame (also called a coil base) 12 and an upper frame 13. Pot 3 is configured to store food to be cooked, including rice and water.

[0023] The protective frame 12 is a portion that stores the pot 3, and is formed in a cylindrical shape with a bottom corresponding to the shape of the pot 3. The protective frame 12 is formed slightly larger than the pot 3 so as to face the outer circumferential surface of the pot 3 with a gap therebetween. The protective frame 12 is made of a heat-resistant resin, and is a member having higher rigidity than the upper frame 13. The pot 3 has an annular flange portion 3a that protrudes outward from the upper opening. The pot 3 is stored (suspended) inside the protective frame 12 as the flange portion 3a is supported from below by the pot storage portion 1.

[0024] A pot heating section 14 for heating the pot 3 is arranged on the outer peripheral surface of the protective frame 12. In this embodiment, a pot heating section 14 for induction heating the pot 3 is arranged on the outer peripheral surface of the protective frame 12 so as to face the outer peripheral surface of the pot 3. The pot heating section 14 comprises a ring-shaped inner bottom heating coil 14A and a ring-shaped outer bottom heating coil 14B. The inner bottom heating coil 14A is arranged so as to face the periphery of the center of the bottom of the pot 3 across the protective frame 12. The outer bottom heating coil 14B is arranged so as to face the side bottom portion (corner portion) of the pot 3 across the protective frame 12.

[0025] Opening 12a is provided in the center of the bottom of protective frame 12. Pot temperature detection unit 15 for measuring the temperature of pot 3 is arranged in opening 12a so as to be able to come into contact with the bottom of pot 3 stored in pot storage unit 11. Since the temperature of pot 3 is approximately the same as the temperature of the food being cooked in pot 3, by detecting the temperature of pot 3 with pot temperature detection unit 15, the temperature of the food being cooked in pot 3 can be detected.

[0026] As shown in FIG. 2, the space surrounded by the cooker main body 1 and the pot storage unit 11 is provided with a control unit 16 that controls the pot heating unit 14 to execute the rice cooking process. The control unit 16 is provided with a memory unit that stores multiple rice cooking sequences for cooking rice. Here, the "rice cooking sequence" refers to a rice cooking procedure in which the power supply time, heating temperature, heating time, heating output, etc. of the pot heating unit 14 are predetermined for each step of the rice cooking process, which mainly consists of four steps: water absorption, heating, boiling maintenance, and steaming. Each rice cooking sequence corresponds to one of multiple rice cooking courses. The control unit 16 controls the operation of each part and each device based on the rice cooking course selected by the operation unit and the temperature detected by the pot temperature detection unit 15, etc., to execute the rice cooking process.

[0027] Inside the lid body 2, a display unit 4 and an operation unit (not shown) are provided so as to contact the upper surface of the lid body 2. The display unit 4 is a display unit such as a liquid crystal display that displays various information such as the cooking course and cooking time. The operation unit is an operation unit that allows a specific cooking course to be selected from multiple cooking courses such as the white rice course, brown rice course, and white rice (soft) course. The operation unit is composed of multiple buttons such as a rice cooking start button so that in addition to selecting a cooking course, it can also instruct the start, cancellation, and reservation of cooking. The upper surface of the lid body 2 is configured so that the multiple buttons can be pressed. The user can select a specific cooking course using the operation unit (not shown) while referring to the display content of the display unit 4, and instruct the start of cooking.

[0028] The lid body 2 is rotatably attached to a hinge part H1 located at the upper rear part of the cooker body 1 (upper right side in FIG. 2), and is configured to cover the upper opening of the pot 3 in an openable and closable manner by rotating about the hinge part H1. The lid body 2 is also configured to be engageable with the upper front part of the cooker body 1 (upper left side in FIG. 2). When an opening button 5 provided on the upper front part of the lid body 2 as shown in FIG. 1 is pressed, the lid body 2 is released from engagement with the upper front part of the cooker body 1, and rotates about the hinge part H1 to open the upper opening of the pot 3. The lid body 2 includes an outer lid 21 and an inner lid 22 that is detachably attached to the outer lid 21 as shown in FIG. 2.

[0029] 3 is a bottom view showing the structure of the inner lid 22 of the lid body 2. The inner lid 22 of the lid body 2 is provided with an annular gasket 23 at a position corresponding to the flange portion 3a. When the lid body 2 is in the closed position (the position shown in FIG. 2), the gasket 23 closes the gap between the flange portion 3a of the pot 3 and the inner lid 22 of the lid body 2. The inner lid 22 of the lid body 2 is also provided with a steam inlet 22a that takes in steam generated in the pot 3 when the control unit 16 executes the rice cooking process. In this embodiment, the steam inlet 22a is composed of multiple through holes smaller than rice grains so as to prevent rice grains from passing through while allowing steam and sticky rice to pass through.

[0030] 4 is an exploded perspective view showing the components of pot 3 and outer lid 21 of lid body 2. Outer lid 21 includes, as its components, outer lid chassis 24, steam passage forming member 25, and steam passage lid 26.

[0031] The outer lid chassis 24 is a member that supports each component of the outer lid 21. The outer lid chassis 24 is provided with a through hole 24a that is fluidly connected to the steam inlet 22a of the inner lid 22. When the inner lid 22 is attached to the outer lid 21, an annular packing (not shown) is provided between the inner lid 21 and the outer lid 21 around the steam inlet 22a and the through hole 24a of the inner lid 22. The packing guides the steam taken in from the steam inlet 22a to the through hole 24a. The packing may be provided in the inner lid 22 or the outer lid 21.

[0032] A steam passage forming member 25 is attached to the outer lid chassis 24. The steam passage forming member 25 is attached to the outer lid chassis 24 by a plurality of fastening members such as screws. The steam passage forming member 25 is a component that guides the steam taken in from the through hole 24a to the steam exhaust port 21a provided on the upper surface of the outer lid 21. The steam exhaust port 21a is an opening for exhausting the steam generated in the pot 3 to the outside of the cooking device. The steam exhaust port 21a is provided at a position away from the steam inlet port 22a in a top view of the lid body 2 in the thickness direction (the vertical direction in FIG. 2). In this embodiment, the steam passage forming member 25 forms a steam passage that is fluidly connected to the steam inlet port 22a and the steam exhaust port 21a. The steam passage is provided with a sticky paste reservoir 27 that stores sticky paste. In this embodiment, the sticky paste reservoir 27 is formed by the steam passage forming member 25 and the steam passage lid 26.

[0033] Fig. 5 is a perspective view of the steam passage forming member 25. Fig. 6 is a bottom view of the steam passage forming member 25. Fig. 7 is a top view of the steam passage forming member 25. Fig. 8 is a top view of the steam passage cover 26. Fig. 9 is a cross-sectional view taken along the line A1-A1 of Fig. 7.

[0034] The sticky material reservoir 27 is a substantially box-shaped space. The bottom wall of the sticky material reservoir 27 has an inlet 27a that is fluidly connected to the steam inlet 22a. The inlet 27a is formed to have a larger opening area than the steam inlet 22a and the steam outlet 21a.

[0035] As shown in FIG. 7, sticky reservoir 27 has a side wall surface 27b that curves away from steam outlet 21a as it moves from steam inlet 22a to steam outlet 21a in top view.

[0036] In top view, sticky material reservoir 27 has rear wall surface 27c located downstream of steam exhaust port 21a from steam inlet 22a toward steam exhaust port 21a. Rear wall surface 27c has protruding portion 27ca protruding away from steam exhaust port 21a. Side wall surface 27b is continuously connected to protruding portion 27ca. In top view, protruding portion 27ca has guide surface 27cb that is inclined or curved so as to guide the sticky material that has entered protruding portion 27ca toward side wall surface 27b, as shown by the solid arrow in Fig. 7.

[0037] The sticky reservoir 27 has one or more step portions 27d between the steam inlet 22a and the steam outlet 21a when viewed from above. In this embodiment, the sticky reservoir 27 has one step portion 27d between the inlet 27a and the steam outlet 21a when viewed from above. The height of step portion 27d is, for example, higher than the thickness of the bottom wall of the sticky reservoir 27.

[0038] Moreover, when viewed from above, sticky reservoir 27 is configured asymmetrically with respect to an imaginary straight line L1 (shown by a dashed line in FIG. 7) that extends from steam inlet 22a toward steam outlet 21a and passes through center 21aa of steam outlet 21a. In this embodiment, sticky reservoir 27 has side wall surface 27b on either the left or right side of imaginary straight line L1 (on the right side of imaginary straight line L1 in FIG. 7).

[0039] The upper wall of the sticky reservoir 27 is formed of a steam passage lid 26. In this embodiment, the steam passage lid 26 is configured to be detachable from the upper opening of the steam passage forming member 25. The steam passage lid 26 has a cylindrical portion 26a at a position corresponding to the steam exhaust port 21a. The sticky reservoir 27 is in fluid communication with the steam exhaust port 21a through the cylindrical portion 26a.

[0040] The sticky material reservoir 27 has a bottom wall surface 27e that guides the sticky material as indicated by a solid arrow in Fig. 9. The bottom wall surface 27e is inclined upward from the steam inlet 22a to the steam outlet 21a.

[0041] According to the cooking device of this embodiment, since the sticky paste reservoir 27 has the side wall surface 27b, the sticky paste can be guided away from the steam exhaust port 21a by the side wall surface 27b. This makes it possible to prevent the sticky paste from being discharged to the outside of the cooking device through the steam exhaust port 21a. In addition, it is possible to eliminate the need to provide a rib on the sticky paste reservoir 27, and the cleaning of the sticky paste can be improved.

[0042] In addition, according to the cooking device of this embodiment, since the sticky paste reservoir 27 has the protruding portion 27ca, the sticky paste can be collided with the protruding portion 27ca located away from the steam exhaust port 21a, and the momentum of the sticky paste can be suppressed. Furthermore, since the side wall surface 27b is continuously connected to the protruding portion 27ca, the volume of the space away from the steam exhaust port 21a can be secured widely. This makes it possible to further suppress the sticky paste from being discharged to the outside of the cooking device through the steam exhaust port 21a.

[0043] In addition, according to the cooking device of this embodiment, since the protruding portion 27ca has the guide surface 27cb, the sticky paste can be guided along the protruding portion 27ca and the side wall surface 27b. This makes it possible to further prevent the sticky paste from being discharged to the outside of the cooking device through the steam exhaust port 21a. In addition, it is possible to eliminate the need to provide a rib on the sticky paste reservoir 27, improving the cleaning ability.

[0044] In addition, according to the cooking device of this embodiment, since the sticky paste reservoir 27 has the step portion 27d, the momentum of the sticky paste can be further suppressed by the sticky paste colliding with the step portion 27d. This further suppresses the sticky paste from being discharged to the outside of the cooking device through the steam exhaust port 21a. In addition, it is possible to eliminate the need to provide a rib on the sticky paste reservoir 27, improving the cleaning ability.

[0045] Furthermore, according to the cooking device of this embodiment, since the sticky paste reservoir 27 is configured asymmetrically with respect to the imaginary straight line L1, the flow of the sticky paste can be biased to either the left or right side with respect to the imaginary straight line L1. This allows, for example, the sticky paste to be intentionally controlled to flow along the side wall surface 27b, and further prevents the sticky paste from being discharged to the outside of the cooking device through the steam exhaust port 21a. Also, it is possible to eliminate the need to provide ribs in the sticky paste reservoir 27, improving cleaning properties.

[0046] Furthermore, according to the cooking device of this embodiment, since the sticky paste reservoir 27 has the side wall surface 27b on either the left or right side of the imaginary straight line L1, no side wall surface 27b is provided on the other side, and an increase in the volume of the sticky paste reservoir 27 can be suppressed. Also, the periphery of the side wall surface 27b and the protruding portion 27ca is likely to heat up due to the influence of the heat of the sticky paste. By not providing the side wall surface 27b on either the left or right side of the imaginary straight line L1, components that are sensitive to heat can be placed around the other side.

[0047] In addition, according to the cooking device of this embodiment, since the sticky rice reservoir 27 has the bottom wall surface 27e, the force of the sticky rice that has entered the sticky rice reservoir 27 can be suppressed by utilizing gravity. Also, the sticky rice that has entered the sticky rice reservoir 27 can be returned to the inlet portion 27a.

[0048] In addition, according to the cooking device of this embodiment, the entrance 27a of the sticky rice reservoir 27 has a larger opening area than the steam inlet 22a and the steam outlet 21a, so that the momentum of the sticky rice that has entered the sticky rice reservoir 27 can be suppressed. This can prevent the sticky rice from being discharged to the outside of the cooking device through the steam outlet 21a. In addition, the need to provide a rib on the sticky rice reservoir 27 can be eliminated, and the cleaning of the sticky rice can be improved. In addition, for example, by making the opening area of ​​the entrance 27a large enough for a user's finger to enter, the user's finger can enter the sticky rice reservoir 27 through the entrance 27a to clean the inside of the sticky rice reservoir 27. This can eliminate the need to configure the sticky rice reservoir 27 to be detachable from the lid body 2 (outer lid 21).

[0049] Furthermore, the cooking device according to the present embodiment has the above-mentioned configuration, and therefore the moving path of the sticky paste can be shortened. As a result, the volume of sticky paste reservoir 27 can be reduced by 20 to 30% compared to the conventional case.

[0050] The present disclosure is not limited to the above embodiment, and can be implemented in various other aspects. For example, in the above, the sticky reservoir 27 is configured asymmetrically with respect to the virtual straight line L1, but the present disclosure is not limited to this. For example, the sticky reservoir 27 may be configured symmetrically with respect to the virtual straight line L1. That is, the sticky reservoir 27 may have two side wall surfaces 27b and two protrusions 27ca. The sticky reservoir 27 may also have two side wall surfaces 27b and two protrusions 27ca that are different in size from each other.

[0051] In addition, in FIG. 9, the upper wall surface of the steam passage cover 26 is shown as being flat, but the present disclosure is not limited thereto. For example, as shown in FIG. 10, the upper wall surface of the steam passage cover 26 may have an upper wall surface 26b that is inclined downward from the upper end of the rear wall surface 27c (e.g., the protruding portion 27ca) toward the steam exhaust port 21a (the cylindrical portion 26a) in a side view perpendicular to the thickness direction of the cover body 2. That is, the sticky paste reservoir 27 may have an upper wall surface 26b that is inclined downward from the upper end of the rear wall surface 27c toward the steam exhaust port 21a in a side view. This allows the flow of sticky paste that collides with the rear wall surface 27c (e.g., the protruding portion 27ca) and moves in the opposite direction to be directed downward, as shown by the solid arrow in FIG. 10. As a result, it is possible to further prevent the sticky paste from being discharged to the outside of the cooking device through the steam exhaust port 21a. In addition, it is possible to eliminate the need to provide a rib on the sticky paste reservoir 27, and it is possible to improve the cleaning ability.

[0052] Any of the various embodiments described above may be appropriately combined to achieve the effects of each of the embodiments.

[0053] Although the present disclosure has been fully described in connection with the preferred embodiment with appropriate reference to the 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.
