[0009] Hereinafter, embodiments will be described with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference characters and description thereof will not be repeated.

[0010] A cooking device 1 according to an embodiment will be described with reference to Figs. 1 to 5. Fig. 1 is a perspective view showing the cooking device 1 according to the embodiment. Fig. 2 is a perspective view of the cooking device 1 according to the embodiment, showing the state in which the outer lid 45 is open and the first inner lid 40 or the second inner lid 46 is partially removed. Fig. 3 is a cross-sectional view of the cooking device 1 according to the embodiment. Fig. 4 is a perspective view showing the first inner lid 40 or the second inner lid 46 of the cooking device 1 according to the embodiment. Fig. 5 is a cross-sectional view of the first inner lid 40 or the second inner lid 46 of the cooking device 1 according to the embodiment.

[0011] 1 has a heating function for heating food ingredients. Cooking appliance 1 includes, for example, an electric pot or a rice cooker.

[0012] 2 and 3, the cooking device 1 includes a cooking device body 2, an inner pot 3, and a lid 4. The inner pot 3 is housed in the cooking device body 2. The lid 4 is attached to the cooking device body 2.

[0013] The cooker body 2 has a wide-mouthed, deep-bottomed container shape. The cooker body 2 has a top surface 23. The cooker body 2 has a first opening 2B on the top surface 23 that leads to the first interior 2A. The first opening 2B is, for example, approximately circular. The first interior 2A is, for example, approximately cylindrical in shape with its axis passing through the center of the first opening 2B. A heating section 22 that generates heat is provided at the bottom 21 of the first interior 2A. The first interior 2A is a space in which the inner pot 3 is housed.

[0014] The inner pot 3 is a pot sized to be housed in the first interior 2A. The body portion 33 (see FIG. 3) of the inner pot 3 is shaped to fit along the wall surface 24 (see FIG. 3) that contacts the first interior 2A of the cooker body 2. The inner pot 3 has a second opening 3B that communicates with the second interior 3A, and a flange portion 31 that extends from the edge that contacts the second opening 3B toward the outside in a direction that intersects with the body portion 33. The second interior 3A is a space for storing ingredients to be heated. The second opening 3B is, for example, substantially circular. The second interior 3A is, for example, substantially cylindrical in shape with its axis passing through the center of the second opening 3B. The ingredients are moved into and out of the inner pot 3 through the second opening 3B. The operator (user) of the cooking appliance 1 holds the flange portion 31 of the inner pot 3 and moves it. The inner pot 3 held by the user is housed in the cooker body 2 through the first opening 2B with the inner pot bottom 32, which faces the portion having the second opening 3B, facing the heating unit 22. The inner pot 3 housed in the cooker body 2 has the inner pot bottom 32 supported by the heating unit 22 and the second opening 3B communicating with the outside of the cooker body 2.

[0015] When the inner pot 3 is housed in the cooker body 2, the lid body 4 covers the first opening 2B of the cooker body 2, the second opening 3B of the inner pot 3, and the top surface 23 of the cooker body 2 from the outside of the cooker body 2. In this way, the lid body 4 covers the cooker body 2 and the inner pot 3. The lid body 4 has a first inner lid 40 and an outer lid 45.

[0016] 3 to 5, the first inner lid 40 has an inner lid main body 410 and a seal member 420. The seal member 420 is attached to the inner lid main body 410.

[0017] As shown in Figures 4 and 5, the inner lid main body 410 has an inner lid frame 411, a cover 412, an inner lid flange 413, an outer protrusion 414, and a hook 415. The inner lid frame 411 is frame-shaped with a space surrounded by members. The cover 412 is provided in the space surrounded by the inner lid frame 411. The inner lid frame 411 and the cover 412 are integrally molded using resin. The outer protrusion 414, the inner lid flange 413, and the hook 415 are provided on the outer periphery of the inner lid frame 411.

[0018] The inner lid frame 411 is ring-shaped. The outer diameter of the inner lid frame 411 is equal to the size of the flange 31 of the inner hook 3. The shape of the inner lid frame 411 need not be ring-shaped, but may have corners or angles on the outer and inner peripheral portions.

[0019] The cover portion 412 extends radially inward from one end of the inner lid frame 411. The cover portion 412 functions as a lid. The cover portion 412 may be provided with a hole that penetrates along the axial direction of the inner lid frame 411.

[0020] The inner lid flange 413 is a flange-shaped portion extending radially outward from the other end of the inner lid frame 411. The outer protrusion 414 is a portion protruding radially outward from the outer peripheral wall surface 41A of the inner lid frame 411. The hook portion 415 is a portion protruding radially outward from a part of the outer peripheral surface of the inner lid flange 413.

[0021] The inner lid body 410 is made of resin, which has a lower thermal conductivity than metals such as aluminum or stainless steel. The resin is, for example, an engineering plastic containing polyphenylene sulfide (PPS).

[0022] The seal member 420 has a seal frame 421, a groove 42A, and a seal portion 422. The seal frame 421 is frame-shaped with a space surrounded by a member. The groove 42A is provided on the inner circumferential side of the seal frame 421. The seal portion 422 is provided outside the seal frame 421 in the radial direction of the seal member 420, at a position spaced apart from the seal frame 421 along the axial direction of the seal frame 421.

[0023] The seal frame 421 has a thick ring shape. The outer diameter of the seal frame 421 is larger than the outer diameter of the outer protrusion 414. The inner diameter of the seal frame 421 is larger than the outer diameter of the inner lid frame 411 and smaller than the outer diameter of the outer protrusion 414. The shape of the seal frame 421 does not have to be ring-shaped, and it may have corners or angles on the outer and inner peripheral portions. The groove 42A is provided around the entire circumference of the inner peripheral wall surface 42B of the seal frame 421.

[0024] The seal portion 422 has a ring shape with a certain thickness. The seal portion 422 has an annular portion 423 on one end side and an annular portion 424 on the other end side. The seal portion 422 has an intermediate portion 425 in the middle in the thickness direction, i.e., between the annular portion 423 on one end side and the annular portion 424 on the other end side. The annular portion 423 on one end side is connected to an end of the seal frame 421. The annular portion 424 on the other end side extends toward the axis of the seal frame 421. The annular portion 424 on the other end side has a tip end portion that extends toward the axis of the seal frame 421 with a circular cross section. The seal portion 422 is closer to the axis of the seal frame 421 as it approaches the annular portion 423 on one end side or the annular portion 424 on the other end side, and is farther from the axis of the seal frame 421 as it approaches the intermediate portion 425.

[0025] The seal member 420 is made of flexible rubber. Therefore, by deforming the inner circumferential side of the seal frame 421 so as to expand radially outward, the outer protrusion 414 of the inner lid frame 411 can pass through the space inside the seal frame 421 and reach the position of the groove 42A. Therefore, the seal frame 421 is disposed around the inner lid frame 411. After the outer protrusion 414 reaches the position of the groove 42A, the deformation of the inner lid frame 411 is released, so that the outer protrusion 414 fits into the groove 42A. In this way, the seal member 420 is attached to the inner lid main body 410.

[0026] As shown in Fig. 3, the first inner lid 40 covers the inner pot 3 containing ingredients by having the cover portion 412 of the inner lid body 410 cover the entire inner pot 3, including the center portion of the second opening 3B, from the outside, with the seal portion 422 of the sealing member 420 in contact with the entire circumference of the flange portion 31. Furthermore, when the lid body 4 is closed, the first inner lid 40 is pressed toward the inner pot 3, deforming the seal portion 422 and bringing the seal portion 422 into tight contact with the flange portion 31. As a result, the seal member 420 seals the space between the inner pot 3 and the inner lid body 410. Therefore, the second interior 3A of the inner pot 3 is hermetically sealed by the first inner lid 40.

[0027] The inner pot 3 sealed by the first inner lid 40 is heated by the heating unit 22. As a result, the food ingredients contained in the second interior 3A are heated. As mentioned above, the inner lid body 410 is made of resin, which has a lower thermal conductivity than metals such as aluminum or stainless steel. Therefore, when the inner pot 3 containing food ingredients is covered with the first inner lid 40 and heated, there is less of a temperature difference between the first inner lid 40 and the second interior 3A of the inner pot 3 than when a metal lid is used. As a result, condensation is less likely to form on the surface of the first inner lid 40 facing the inner pot 3.

[0028] Some of the heated ingredients move by riding on air currents generated in the second interior 3A due to the influence of heat, and adhere to the inner pot 3 side surface of the inner lid body 410 and the groove 42A. If ingredients adhering to the first inner lid 40 are left for a certain period of time, the ingredients may spoil. Therefore, when maintaining the cooking appliance 1, the user must also clean the first inner lid 40 and periodically remove ingredients adhering to the first inner lid 40.

[0029] To remove the seal member 420 from the inner lid main body 410, first, the inner peripheral wall surface 42B of the seal frame 421 is deformed by expanding it radially outward. This removes the outer protrusion 414 from the groove 42A. Then, the inner lid frame 411 is moved from the inside to the outside of the seal frame 421, thereby removing the seal member 420 from the inner lid main body 410. As described above, the seal member 420 is detachable from the inner lid main body 410. Therefore, when cleaning the first inner lid 40, the seal member 420 can be removed from the inner lid main body 410. As a result, the first inner lid 40 allows for easier separation of the components compared to when the seal member 420 cannot be easily removed from the inner lid main body 410, for example, when the seal member 420 is sandwiched and fixed between multiple components. Therefore, the first inner lid 40 can be cleaned more easily compared to when the seal member 420 cannot be easily removed from the inner lid main body 410.

[0030] 2 and 3, the outer lid 45 has an outer lid main body 451, a hinge 452, and an inner lid holding portion 453. The hinge 452 and the inner lid main body 410 are attached to the outer lid main body 451.

[0031] Outer lid body 451 is attached to top surface 23 of cooker body 2 via rotatable hinge 452. Outer lid body 451 is a lid large enough to cover second opening 3B of inner pot 3, first opening 2B of cooker body 2, and top surface 23 of cooker body 2 from the outside. By rotating around hinge 452 as a fulcrum, outer lid body 451 can move between a position where it covers second opening 3B of inner pot 3, first opening 2B of cooker body 2, and top surface 23 of cooker body 2 from the outside and covers cooker body 2, and an open position where they are exposed to the outside.

[0032] The inner lid holding portion 453 is provided on the wall surface 45A of the outer lid body 451 facing the cooker body 2. The inner lid holding portion 453 is hook-shaped. The outer lid body 451 is provided with multiple inner lid holding portions 453. The first inner lid 40 is attached to the outer lid 45 by hooking the hook portions 415 onto all of the inner lid holding portions 453. This holds the first inner lid 40 in place on the outer lid 45. As shown in FIG. 3, when the outer lid body 451 is positioned to cover the cooker body 2, the first inner lid 40 held by the outer lid body 451 is positioned so that the inner lid body 410 covers the second opening 3B from the outside of the inner pot 3 and the seal member 420 seals the space between the first inner lid 40 and the inner pot 3.

[0033] 2, the first inner lid 40 can be removed by placing the outer lid main body 451 in the lid open position and then releasing the engagement of the hook portion 415 with the inner lid holding portion 453. In other words, the first inner lid 40 is detachable from the outer lid 45.

[0034] As shown in FIGS. 2 and 3, the cooking appliance 1 further includes a second inner lid 46 that can be attached to the outer lid 45, instead of the first inner lid 40 made of resin. The second inner lid 46 is detachable from the outer lid 45. The second inner lid 46 has a shape similar to that of the first inner lid 40. Like the first inner lid 40, the second inner lid 46 covers the second opening 3B from the outside of the inner pot 3 to lid the inner pot 3. Similarly to the first inner lid 40, the second inner lid 46 is attached to the outer lid 45 by hooking the second inner lid 46 onto the inner lid holding portion 453 of the outer lid main body 451. Like the first inner lid 40, the second inner lid 46 attached to the outer lid 45 covers the inner pot 3 by positioning the outer lid main body 451 in a position to lid the cooking appliance main body 2. Similar to the first inner lid 40, the second inner lid 46 can be removed from the outer lid 45 by releasing the second inner lid 46 from its engagement with the inner lid holding portion 453. It has been described that the second inner lid 46 has a similar shape to the first inner lid 40. However, the shape of the second inner lid 46 may be any shape as long as the second inner lid 46 can cover the second opening 3B and can be attached by being engaged with the inner lid holding portion 453.

[0035] The second inner lid 46 is made of metal such as aluminum or stainless steel. Therefore, when the inner pot 3 containing ingredients is sealed with the second inner lid 46 and heated, condensation is more likely to occur on the surface of the second inner lid 46 facing the inner pot 3 than in the case of the first inner lid 40 made of resin.

[0036] As described above, the first inner lid 40 and the second inner lid 46 are detachable from the outer lid 45. Therefore, either the first inner lid 40 or the second inner lid 46 can be selectively attached to the outer lid 45 to cover the inner pot 3. As a result, either the first inner lid 40 or the second inner lid 46 can be attached to the outer lid 45 depending on the type of food to be heated using the cooking appliance 1.

[0037] Specifically, for example, when heating wheat flour to make a sponge cake, it is undesirable for condensation to form on the surface of the first inner lid 40 or the second inner lid 46 attached to the outer lid 45 facing the second interior 3A. In this case, it is preferable to cover the inner pot 3 with the first inner lid 40, which generates less condensation when heating ingredients than the second inner lid 46, and heat the wheat flour contained in the inner pot 3. On the other hand, when performing waterless cooking of vegetables, for example, it is preferable for condensation to form on the surface of the first inner lid 40 or the second inner lid 46 attached to the outer lid 45 facing the second interior 3A. In this case, it is preferable to cover the inner pot 3 with the second inner lid 46, which generates more condensation when heating ingredients than the first inner lid 40, and heat the vegetables contained in the inner pot 3.

[0038] As shown in FIG. 3, the cooking appliance 1 further includes an identification sensor 5 that identifies whether the outer lid 45 is attached to the first inner lid 40 or the second inner lid 46. The identification sensor 5 is attached to a portion of the outer lid body 451 where the first inner lid 40 and the second inner lid 46 face each other. The identification sensor 5 detects an identification element for distinguishing between the first inner lid 40 and the second inner lid 46. As shown in FIGS. 3 to 5, an identification component 6 that emits the identification element is attached to a portion of the first inner lid 40 or the second inner lid 46 that faces the identification sensor 5 when the first inner lid 40 or the second inner lid 46 is attached to the outer lid 45. Specifically, the identification component 6 is attached to the inner lid flange 413.

[0039] The identification sensor 5 and the identification part 6 will be described in detail with reference to FIG. 3 . For example, the identification sensor 5 detects magnetic force as an identification element. The first inner lid 40 and the second inner lid 46 are distinguished from each other by whether or not magnetic force is detected. The identification part 6 is, for example, a magnet that emits magnetic force, which is an identification element. The identification part 6 is attached to the first inner lid 40. When the first inner lid 40 is attached to the outer lid 45, the identification part 6 attached to the first inner lid 40 approaches the identification sensor 5. Therefore, the identification sensor 5 detects the magnetic force emitted by the identification part 6 attached to the first inner lid 40. The identification sensor 5 identifies the first inner lid 40 by detecting the magnetic force. On the other hand, when the second inner lid 46 is attached to the outer lid 45, the identification part 6 is not attached to the second inner lid 46, so the identification sensor 5 does not detect the magnetic force. The identification sensor 5 identifies the second inner lid 46 by not detecting the magnetic force. Although the identification sensor 5 and the identification part 6 have been described using specific examples, the identification sensor 5 can be a sensor that detects any physical quantity as long as it can distinguish between the first inner lid 40 and the second inner lid 46.

[0040] If it is possible to identify whether the first inner lid 40 or the second inner lid 46 is attached to the outer lid 45 as described above, the cooking appliance 1 can compare information about the ingredients to be heated with information from the identification sensor 5. As a result, the cooking appliance 1 can compare information about the ingredients to be heated with information about whether the first inner lid 40 or the second inner lid 46 is attached to the outer lid 45, and determine whether the ingredients placed in the inner pot 3 can be heated. By making such a determination, the cooking appliance 1 can heat the ingredients placed in the inner pot 3 using a combination of parts that is appropriate for the type of ingredients to be heated.

[0041] For example, if the cooking appliance 1 is equipped with a control unit (not shown) that controls heating, the control unit can control heating using information from the identification sensor 5. Specifically, when heating wheat flour to make a sponge cake, it is preferable to use the first inner lid 40 to cover the inner pot 3 as described above. In this case, the user provides information to the control unit indicating that they will heat wheat flour to make a sponge cake. The control unit determines whether heating can be started based on the information obtained from the identification sensor 5. For example, if the information obtained from the identification sensor 5 indicates the first inner lid 40, the control unit determines that heating can be started. On the other hand, if the information obtained from the identification sensor 5 indicates the second inner lid 46, the control unit determines that heating is not permitted to be started.

[0042] The embodiments of the present invention have been described above with reference to the drawings. However, the present invention is not limited to the above embodiments and can be embodied in various forms without departing from the spirit and scope of the present invention. The drawings mainly show each component in a schematic manner for ease of understanding, and the thickness, length, number, spacing, etc. of each component shown in the drawings may differ from the actual ones due to the convenience of creating the drawings. Furthermore, the materials, shapes, dimensions, etc. of each component shown in the above embodiments are merely examples and are not particularly limited, and various modifications are possible within a scope that does not substantially deviate from the configuration of the present invention.
