The electromagnetic heating device comprises an electromagnetic coil and a coil disc, the electromagnetic coil is wound on the coil disc, in this scheme, the cover plate 14 on the lower side of the coil disc is a metal member, the alternating magnetic field generated by the electromagnetic coil can act on the metal cover plate 14 below, so that the cover plate 14 itself generates heat to radiate heat to the cooking cavity. The illustrated example shows that the top heating device 100 is an infrared heating device for radiating infrared rays to the cooking cavity during cooking. The infrared rays radiated to the cooking cavity can effectively heat the surface food and make the food evenly heated, thereby stimulating the aroma of the food.

[0114] The cooking appliance 1 of the present application also has the function of steam cooking, high-temperature steam can be delivered to the cooking cavity to heat and moisten the food in the cooking cavity, for example, high-temperature steam is supplied to the cooking cavity during the holding stage, which can keep the food such as rice moist and prevent the food from drying and yellowing. Specifically, the cooking appliance 1 also comprises a steam generating device 40 for generating cooking steam to cook the cooking cavity. In order to deliver the cooking steam to the cooking cavity, the cover body 3 is provided with a cooking steam supply channel P11 communicating with the cooking cavity. The cooking steam supply channel P11 is used for supplying steam for cooking the cooking cavity, specifically, it can receive cooking steam from the steam generating device 40 and deliver cooking steam to the cooking cavity.

[0115] The steam generating device 40 can be arranged on the cover body 3 or the pot body 2. Figure 4 An example of the steam generating device 40 arranged on the pot body 2 is schematically shown. As Figure 4As shown, the steam generating device 40 basically comprises a water container 41 and a water container heating device 42. The water container 41 is arranged in the pot body 2 and is capable of storing water for generating the replenishment steam. Optionally, the water container 41 is located in the receiving cavity of the pot body 2 and protrudes from the upper surface of the pot body 2 to facilitate the removal of the water container 41 from the pot body 2. The water container 41 has a top opening for forming an outlet to allow the replenishment steam to overflow. The water container heating device 42 is usually arranged below the water container 41 and is used to heat the water in the water container 41 to generate the replenishment steam. The replenishment steam can enter the replenishment steam supply passage P11 and then enter the cooking cavity to keep the food such as rice in the inner pot 4 moist. When the steam generating device 40 is arranged in the cover body 3, the arrangement position and structure of the water container 41 and the water container heating device 42 are different from those of the example shown in the drawings. Figure 4

[0116] When the cooking appliance 1 is in use, the heating of the food and water in the inner pot 4 generates cooking steam. In order to exhaust the cooking steam to the external environment, the cover body 3 is provided with a cooking steam exhaust passage P12 and an exhaust passage P2, as shown in the drawings. The cooking steam exhaust passage P12 is in communication with the cooking cavity and the exhaust passage P2 is in communication with the cooking steam exhaust passage P12. The cooking steam can first enter the cooking steam exhaust passage P12 and then be exhausted to the external environment through the exhaust passage P2. Figure 5

[0117] For the infrared heating device, one example is that the infrared heating device can be an infrared electric heating tube. For example, an infrared heating element is encapsulated in a glass tube to form an infrared electric heating tube. In this example, the cover body 3 further comprises a light-transmissive isolation plate arranged on the lower side of the infrared electric heating tube. Another alternative example is that the infrared heating device can be an electric heating film arranged on a plate-shaped member and capable of being powered. In this example, the plate-shaped member for arranging the electric heating film is at least partially light-transmissive. Another alternative example is that, as shown in the example, the infrared heating device comprises a radiation plate 110 and a heating assembly 120 for heating the radiation plate 110. The heating assembly 120 generates heat which is transferred to the radiation plate 110. The radiation plate 110 can be heated to radiate infrared rays to the cooking cavity. The radiation plate 110 can be a ceramic plate, a carbon plate made of carbon material, etc. A light-transmissive isolation plate can be arranged on the lower side of the radiation plate 110. Alternatively, the radiation plate 110 is exposed in the cooking cavity, at least part of the lower surface of the radiation plate 110 forms the top surface of the cooking cavity, and further, at least part of the radiation plate 110 forms the top wall of the cooking cavity. The temperature of the radiation plate 110 can be controlled by controlling the power or heating temperature of the heating assembly 120.

[0118] The structure of the cover body 3 is further described by taking the example shown in the drawings as an example. As shown in the drawings, Figure 3 Figure 7 ​​​As shown, the inner liner 9 is provided with an inner liner through hole 20, and the radiation plate 110 is installed at the inner liner through hole 20. The cover plate 14 is arranged below the radiation plate 110. The cover plate 14 is partially provided with a cover plate through hole 21. The cover plate through hole 21 corresponds to the position of the radiation plate 110. In other words, the cover plate through hole 21 is directly below the radiation plate 110. The infrared rays generated by the radiation plate 110 can be radiated towards the inner pot 4 via the inner liner through hole 20 and the cover plate through hole 21.

[0119] As shown in FIG. 1, the top heating device 100 can further include a radiation plate 110. The radiation plate 110 can be arranged on the inner liner 9. The radiation plate 110 can be arranged on the inner liner 9 in a manner that the radiation plate 110 is directly below the inner liner through hole 20. The radiation plate 110 can be arranged on the inner liner 9 in a manner that the radiation plate 110 is directly below the cover plate through hole 21. The radiation plate 110 can be arranged on the inner liner 9 in a manner that the radiation plate 110 is directly below the inner liner through hole 20 and the cover plate through hole 21. Figure 6 and Figure 7 As shown, the inner liner 9 can be provided with a support portion 22. The support portion 22 is arranged around the inner liner through hole 20, and the support portion 22 forms a closed annular structure. The outer edge of the radiation plate 110 can be lapped on the bottom wall of the support portion 22 and abut against the side wall of the support portion 22. The support portion 22 can provide upward support to the radiation plate 110 and limit the movement of the radiation plate 110 in the horizontal direction, facilitating the fixation of the radiation plate 110. One example is that the support portion 22 can be concave downward, and the radiation plate 110 is accommodated in the concave support portion 22. Another example is that the support portion 22 is a planar structure, i.e. not concave. The outer peripheral portion of the radiation plate 110 is sleeved with a peripheral sealing ring 130 to form a seal between the radiation plate 110 and the inner liner 9. The top heating device 100 further includes a fixing member 140. The fixing member 140 can be connected with the inner liner 9, and the outer edge of the radiation plate 110 is clamped between the fixing member 140 and the support portion 22. The fixing member 140 is optionally arranged in an annular shape, which can be connected with the inner liner 9 by clamping, fastening by fasteners such as screws, welding or other suitable methods.

[0120] In addition, the cover body 3 can further include a through hole sealing ring 23. The through hole sealing ring 23 can be arranged on the peripheral portion of the cover plate through hole 21 and located on the side opposite to the side where the pot opening sealing ring 7 is located, specifically between the radiation plate 110 and the inner liner 9, and abuts against the lower surface of the radiation plate 110. The formation of the seal at the cover plate through hole 21 can avoid the steam entering the inside of the cover body 3 through the gap between the radiation plate 110 and the cover plate 14, thereby improving the sealing effect of the cover body 3. For example, a compression ring 24 can be arranged to clamp a part of the through hole sealing ring 23 between the compression ring 24 and the cover plate 14, and the compression ring 24 can be fixed with the cover plate 14 by bendable clamping corners.

[0121] The shape of the inner liner through hole 20, the shape of the cover plate through hole 21, the shape of the support portion 22, and the shape of the through hole sealing ring 23 correspond to the shape of the radiation plate 110. Exemplarily, the radiation plate 110 can be provided with an avoiding notch 111, and the inner liner 9 is provided with a protruding portion 25 protruding towards the center of the inner liner through hole 20, and the protruding portion 25 is engaged with the avoiding notch 111. A part of the steam passage P1 can be provided on the protruding portion 25. In this way, the area of the radiation plate 110 can be designed to be larger, and the steam passage P1 can also be arranged on one side of the radiation plate 110, specifically the rear side, with a suitable area ratio. The steam passage P1 here includes the above-mentioned cooking steam supply passage P11 and / or the cooking steam exhaust passage P12.

[0122] In order to simplify the structure and optimize the use of the space in the cover body 3, the cooking steam supply passage P11 and the cooking steam exhaust passage P12 are formed by one component in the present application, rather than using different components to form the two passages respectively. Specifically, the cover body 3 further includes a steam passage assembly 200 for forming the cooking steam supply passage P11 and the cooking steam exhaust passage P12. The steam passage assembly 200 is located on the upper side of the cover plate 14 and the lower side of the inner liner 9. The steam passage assembly 200 is located on one side of the top heating device 100, specifically the rear side of the top heating device 100. As shown in Figure 8 The inner liner 9 has a recess 26 for accommodating the steam passage assembly 200. The recess 26 is located on the rear side of the inner liner through hole 20 and is recessed upward from the lower surface of the inner liner 9. At least part of the steam passage assembly 200 is accommodated in the recess 26. The size and shape of the recess 26 are adapted to the outer contour of the steam passage assembly 200.

[0123] As shown in Figure 9 , Figure 10 and Figure 11 The steam passage assembly 200 is further provided with a steam receiving port 201 communicating with the cooking steam supply passage P11 and a cooking steam outlet 202. The steam receiving port 201 is used to receive steam from the steam generating device 40, and the cooking steam outlet 202 is used to communicate the cooking steam supply passage P11 with the cooking cavity. The position of the steam receiving port 201 corresponds to the outlet of the water container 41, specifically above the water container 41. Figure 4 The steam flow path is schematically indicated by arrows. Specifically, the steam generated after the water in the water container 41 is heated enters the cooking steam supply passage P11 through the steam receiving port 201, flows along the cooking steam supply passage P11, and enters the cooking cavity through the cooking steam outlet 202.

[0124] The steam passage assembly 200 is further provided with a cooking steam inlet 203 and a cooking steam outlet 204 which are in communication with the cooking steam discharge passage P12. The cooking steam inlet 203 is configured to communicate the cooking steam discharge passage P12 with the cooking cavity, and the cooking steam outlet 204 is configured to discharge steam in the cooking steam discharge passage P12. The lid body 8 is provided with the steam discharge passage P2 as described above. The cooking steam outlet 204 is positioned corresponding to the steam discharge passage P2 of the lid body 8. The cover plate 14 further comprises a steam valve 27 and a steam seal 28 which form the steam discharge passage P2 and are vertically disposed in the lid body 8. The steam seal 28 is disposed in the upwardly protruding cylindrical wall 37 of the lid body 8 and abuts against the bottom of the steam valve 27 and the upper surface of the steam passage assembly 200. Figure 5 The steam flow path is schematically indicated by arrows, in particular, steam in the cooking cavity enters the cooking steam discharge passage P12 via the cooking steam inlet 203, flows along the cooking steam discharge passage P12, and flows to the steam discharge passage P2 via the cooking steam outlet 204, and then is discharged to the ambient environment.

[0125] The steam passage assembly 200 comprises a passage bottom shell 205 and a passage top plate 206. The passage bottom shell 205 is positioned below the passage top plate 206 and is coverable to the passage bottom shell 205. The steam seal 28 abuts against the upper surface of the passage top plate 206. The outer periphery of the passage bottom shell 205 and the passage top plate 206 correspond in shape and size, and the outer periphery of the passage bottom shell 205 and the passage top plate 206 is schematically shown as a substantially triangular shape in the drawings.

[0126] The passage bottom shell 205 is connected with the passage top plate 206 and forms the cooking steam discharge passage P12 and the steam supply passage P11 therebetween. Further, the two steam passages P1 are partially formed by the passage bottom shell 205 or components thereon, and partially formed by the passage top plate 206 or components thereon. The steam passage assembly 200 comprises two passage seals, i.e. a cooking steam passage seal and a steam supply passage seal 207, for forming seals at the cooking steam discharge passage P12 and the steam supply passage P11, respectively. In one example, the cooking steam discharge passage P12 and the steam supply passage P11 are provided at different regions of the passage bottom shell 205. In this example, the passage bottom shell 205 forms bottom walls of the two steam passages P1, and the two passage seals are sandwiched at the passage walls at different positions, so that the passage bottom shell 205 and the passage top plate 206 enclose the two steam passages P1. Alternatively, the passage bottom shell 205 is provided with a pressing plate which is configured to form the bottom walls of the two steam passages P1; in this arrangement, the pressing plate can be configured to fix the passage seals which abut against the passage top plate 206. Thus, the pressing plate, the passage seals and the passage top plate 206 enclose the two steam passages P1.

[0127] Another example is that, as shown in Figure 9 In this example, the channel bottom shell 205 forms the bottom wall of the cooking steam discharge passage P12, so that the channel bottom shell 205 and the channel top plate 206 enclose the cooking steam discharge passage P12. The steam channel assembly 200 further comprises a supplementary cooking steam passage member 208, which is arranged between the channel bottom shell 205 and the channel top plate 206, for forming the supplementary cooking steam supply passage P11.

[0128] The steam channel assembly 200 is entirely mounted on the detachable cover assembly 13, so that the steam channel assembly 200 is removed from the cover body 3 together with the detachable cover assembly 13, and the two steam passages P1 on the steam channel assembly 200 can be cleaned. Specifically, the channel bottom shell 205 and the channel top plate 206 are connected with the detachable cover assembly 13, so as to be removed from or mounted to the cover body 3 together with the detachable cover assembly 13. Thus, the steam channel assembly 200 can be removed from the cover body 3, so as to clean the two steam passages P1. The cover plate through hole 21 is adjacent to the front end portion 36a of the detachable cover assembly 13. The steam channel assembly 200 is arranged adjacent to the rear end portion of the detachable cover assembly 13. The cover plate through hole 21 and the steam channel assembly 200 can be arranged in front and back, with the cover plate through hole 21 in front and the steam channel assembly 200 in back, so that the cover plate through hole 21 can be designed to occupy a larger cooking area. The cover plate 14 is defined with a cooking area at the pot opening sealing ring 7, and the cover plate through hole 21 is located in the cooking area and occupies an area greater than 3 / 5 of the area of the cooking area, for example, an area ratio of 8 / 10, 4 / 5, etc. The steam channel assembly 200 is arranged at a region outside the cover plate through hole 21.

[0129] In the illustrated example, the channel top plate 206 is detachably connected with the channel bottom shell 205, so as to be removed from or mounted to the cover body 3 together with the channel bottom shell 205. When the steam passages P1 need to be cleaned, the whole of the steam channel assembly 200 and the detachable cover assembly 13 can be removed from the cover body 3, and then the channel top plate 206 can be detached from the channel bottom shell 205. In this way, part of the steam passages P1 on the channel top plate 206 are exposed, and part of the steam passages P1 on the channel bottom shell 205 are also exposed. The detachable cover assembly 13 and the channel bottom shell 205 removed from the cover body 3 can be cleaned by the user with water, and the channel top plate 206 removed from the cover body 3 can be cleaned by the user with water alone. The user can easily clean the steam passages P1, and the cleaning effect is good.

[0130] The channel bottom shell 205 is provided with the above-mentioned cooking steam inlet 203 and the cooking steam outlet 204. In other examples not shown, the cover plate 14 can be provided with the above-mentioned cooking steam inlet 203 and the cooking steam outlet 204, and the channel bottom shell 205 is provided with a channel structure at positions corresponding to the steam inlet port 201 and the cooking steam outlet 204. A sealing member is sandwiched between the channel structure and the cover plate 14. In the example shown in the figure, the steam generating device 40 is arranged in the pot body 2, and the channel bottom shell 205 is provided with the above-mentioned steam inlet port 201 to admit steam from the lower side. In the example where the steam generating device 40 is arranged in the cover body 3, the channel top plate 206 is provided with the above-mentioned steam inlet port 201 to admit steam from the upper side.

[0131] Referring back to Figure 6 and Figure 8 , the cover body 3 further comprises a temperature measuring device 50 for detecting the temperature of the steam in the cooking cavity. The temperature measuring device 50 comprises a temperature measuring element 51. The channel top plate is provided with a temperature measuring hole 219, and at least a portion of the temperature measuring element 51 is arranged in the cooking steam discharge channel P12 via the temperature measuring hole 219.

[0132] The configuration of the steam channel assembly 200 will be further described below with reference to the example shown in the figure.

[0133] As shown in Figure 12 and Figure 13 , the channel bottom shell 205 extends beyond the rear portion of the cover plate 14 in the longitudinal direction and the lateral direction of the horizontal plane, and specifically, the steam channel assembly 200 / the channel bottom shell 205 is arranged astride the cover plate 14 and the cover plate seat 15. The steam inlet port 201 is located at the lateral end portion 210 of the channel bottom shell 205 in the lateral direction. The steam generating device 40 is arranged at the corner portion of the rear end of the pot body 2, and the lateral end portion 210 of the channel bottom shell 205 in the lateral direction corresponds to the corner portion of the cover body 3. In this way, the position of the steam inlet port 201 can be corresponded to the water container 41 of the steam generating device 40 in the up-down direction, and steam enters the steam inlet port 201 from the lower side, so that the steam path between the steam inlet port 201 and the water container 41 is short and straight. At least the cooking steam outlet 202 is located at the front end portion 211 of the channel bottom shell 205 in the longitudinal direction. For the example shown in the figure, both the cooking steam outlet 202 and the cooking steam inlet 203 are arranged at the front end portion 211 of the channel bottom shell 205 in the longitudinal direction. The cooking steam outlet 204 is spaced apart from the cooking steam inlet 203 in the longitudinal direction and is located on the longitudinal center line of the cover plate 14.

[0134] The supplementary steam supply channel P11 has a supplementary steam outlet 202 at one end and a steam inlet 201 at the other end. In other words, the steam inlet 201 and the supplementary steam outlet 202 are located at opposite ends of the supplementary steam supply channel P11. Optionally, the supplementary steam supply channel P11 is a straight channel, with its centerline forming a predetermined angle with the centerline extending in the front-rear direction of the cover plate 14. Furthermore, the supplementary steam supply channel P11 is inclined relative to the longitudinal centerline of the cover plate 14. It should be noted that in the example of the detachable cover assembly 13, the longitudinal centerlines of both the cover plate 14 and the detachable cover assembly 13 are collinear.

[0135] It should be noted that the terms "longitudinal" and "longitudinal direction" used in this article refer to the front-to-back direction, while "lateral" and "lateral direction" refer to the left-to-right direction.

[0136] like Figure 14 As shown, to secure the channel bottom shell 205 to the detachable cover assembly 13, the cover plate seat 15 includes a plate-shaped seat support portion 29, which protrudes from the rear of the cover plate 14. The steam channel assembly 200 / channel bottom shell 205 spans across the cover plate 14 and the seat support portion 29. The channel bottom shell 205 can be connected to the seat support portion 29 by a suitable method such as channel welding or fastener connection such as screws. The detachable cover assembly 13 is provided with a supplementary steam docking cover 30, which can be closed onto the top opening of the water container 41 when the cover body 3 is closed. The supplementary steam docking cover 30 is also provided with a supplementary steam docking seal 31, which forms a seal between the water container 41 and the supplementary steam docking cover 30 when the cover body 3 is closed. The supplementary steam docking cover 30 is provided with a supplementary steam inlet 35, from which supplementary steam enters the supplementary steam supply channel P11. The steam docking cover 30 is connected to or integrally disposed on the near rear end 36b of the cover plate seat 15 (see...). Figure 13 The area is specifically located in the seat support part 29.

[0137] A channel seal is disposed between the channel bottom shell 205 and the channel top plate 206 to form a sealed steam channel. The channel top plate 206 can be detachably connected to the channel bottom shell 205 via a snap-fit ​​structure to ensure a tight fit between the channel bottom shell 205, the channel top plate 206, and the channel seal. At least a portion of the snap-fit ​​structure is disposed on the upper side of the seat support 29. In some examples, the channel seal can be directly installed on the channel bottom shell 205 and sealed by the channel top plate 206 connected to the removable cover assembly 13. In case of leakage, the sealing effect can be enhanced by adjusting the compression of the channel seal or by adjusting the mating dimensions between the channel top plate 206 and the channel bottom shell 205. Furthermore, adjusting the compression of the channel seal is independent of the installation of the removable cover assembly 13, thus not affecting the installation and fastening force and assembly feel of the removable cover assembly 13, thereby improving the user experience.

[0138] In some examples, such as the illustrated example, the buckle structure includes a fixed buckle 212 and a movable buckle 213, which correspond to different side edges of the steam channel assembly 200, respectively. The fixed buckle 212 is detachably buckled to one buckle position of the channel top plate 206; the movable buckle 213 is detachably buckled to another buckle position of the channel top plate 206. The fixed buckle 212 can provide a fixed position, so that the channel top plate 206 is positioned fixedly at one side edge, ensuring that the installation position of the channel top plate 206 is accurate and not dislocated, and guaranteeing the sealing effect. The buckle position is configured as a convex buckle protruding from the vertically extending side surface of the channel top plate 206. The convex buckle located on the side surface is close to the detachable cover assembly 13, facilitating the side edge buckling of the movable buckle, and fully utilizing the empty space on the periphery of the steam channel assembly 200.

[0139] Specifically, the fixed buckle 212 is connected to the channel bottom shell 205 and is provided with a buckle opening 214. The movable buckle 213 is rotatably connected to the seat support portion 29 of the cover plate seat 15. The channel top plate 206 is provided with a first convex buckle 215 matched with the fixed buckle 212 and a second convex buckle 216 matched with the movable buckle 213. The first convex buckle 215 can be buckled into the buckle opening 214 of the fixed buckle 212, and the second convex buckle 216 can be buckled from the upper side by the movable buckle 213. The seat support portion 29 is spaced apart and provided with an upwardly protruding column, and the movable buckle 213 is rotatably connected to the column. When assembled, the first convex buckle 215 is buckled into the buckle opening 214 of the fixed buckle 212 first, to realize the fixation of one side edge of the assembly; and then the movable buckle 213 is rotated to be buckled to the second convex buckle 216, to realize the fixation of the other side edge of the assembly. When disassembled, the movable buckle 213 is unlocked first, and then the fixed buckle 212 is separated. Alternatively, the movable buckle 213 is rotatably connected to the channel bottom shell 205. This scheme can make the position of the movable buckle 213 upwardly lifted, without interference between the movable buckle 213 and the upper surface of the cover plate seat, so that the rotation space of the movable buckle 213 is larger, facilitating the user to operate more conveniently.

[0140] In some alternative examples, the fixed buckle 212 is not provided, and the movable buckle 213 is located at different side edges of the steam channel assembly 200, respectively. The channel top plate 206 is fixed by the movable buckles 213 located at different side edges, and the installation and disassembly of the channel top plate 206 are convenient and flexible.

[0141] The channel bottom shell 205 comprises an inlet and outlet centralized distribution portion 217, which is provided with a steam passage 218 for connecting the steam passage P1 with the cooking cavity. The steam passage 218 comprises a supplementary cooking steam outlet 202 connected with the supplementary cooking steam supply passage P11 and / or a cooking steam inlet 203 connected with the cooking steam exhaust passage P12. That is, the supplementary cooking steam outlet 202 and / or the cooking steam inlet 203 are arranged in the inlet and outlet centralized distribution portion 217. In the illustrated example, the supplementary cooking steam outlet 202 and the cooking steam inlet 203 are arranged in the inlet and outlet centralized distribution portion 217. The cover plate 14 is provided with a centralized distribution portion passing hole 32, and the inlet and outlet centralized distribution portion 217 is arranged in the centralized distribution portion passing hole 32.

[0142] The channel bottom shell 205 is provided with a bottom shell lower protrusion 205a, which at least partially constitutes the inlet and outlet centralized distribution portion. The cover plate 14 is provided with a cover plate lower recess 14a, and the bottom shell lower protrusion 205a is at least partially combined with the cover plate lower recess 14a. The channel bottom shell 205 is limited in the cover plate lower recess 14a at the downwardly protruding bottom shell lower protrusion 205a, so that the cover plate limits the horizontal position of the channel bottom shell 205, avoiding horizontal movement of the channel bottom shell 205 relative to the cover plate 14.

[0143] The channel bottom shell 205 can be closer to the cover plate 14 at the downwardly protruding inlet and outlet centralized distribution portion 217, and the inlet and outlet centralized distribution portion 217 is limited in the cover plate through hole 21. On the one hand, the steam passage 218 on the inlet and outlet centralized distribution portion 217 can be connected with the cooking cavity, and on the other hand, the cover plate 14 limits the horizontal position of the channel bottom shell 205 at the inlet and outlet centralized distribution portion 217, avoiding horizontal movement of the channel bottom shell 205 relative to the cover plate 14. In an example, the inlet and outlet centralized distribution portion 217 is a flange-shaped protrusion, which extends into or through the centralized distribution portion passing hole 32. The flange surface can abut the edge of the centralized distribution portion passing hole 32, and the protrusion can be limited in the centralized distribution portion passing hole 32. This assembly structure enables the inlet and outlet centralized distribution portion to be stably retained on the cover plate.

[0144] The inlet and outlet centralized distribution portion 217 is located at the front end portion 211 of the channel bottom shell 205 in the longitudinal direction. In design, the steam passage assembly 200 in the longitudinal direction can be better utilized to arrange the steam passage P1 with a longer extension path, so that the steam passage assembly 200 is miniaturized in the longitudinal direction, and thus the part of the steam passage assembly on the cover plate 14 has a smaller size and a smaller area ratio. The inlet and outlet centralized distribution portion 217 is configured to be adapted in shape and size to the centralized distribution portion passing hole 32. The structure between the inlet and outlet centralized distribution portion 217 and the cover plate 14 can be more compact, which facilitates effective limitation of the horizontal movement of the channel bottom shell 205 relative to the cover plate 14, and in addition, the overall appearance of the inner side of the cover body 3 can be improved in shape.

[0145] The cover body 3 further comprises a steam cover 33 and a steam area seal 34. The steam cover 33 is located on both sides of the inlet and outlet concentrated distribution part 217 and the lower side of the cover plate 14, so as to fix the inlet and outlet concentrated distribution part 217 to the cover plate 14. The steam area seal 34 is located between one of the steam cover 33 and the inlet and outlet concentrated distribution part 217 and the edge of the concentrated distribution part through hole 32. For example, as shown in the example, the steam area seal 34 is arranged between the cover plate 14 and the inlet and outlet concentrated distribution part 217 to form a seal therebetween. The inlet and outlet concentrated distribution part 217 is located in the concentrated distribution part through hole 32 and connected to the steam cover 33, the edge of the concentrated distribution part through hole 32 can be clamped between the inlet and outlet concentrated distribution part 217 and the steam cover 33, and the steam area seal 34 is clamped between the cover plate 14 and the inlet and outlet concentrated distribution part 217. Alternatively, the steam cover 33 is welded to the inlet and outlet concentrated distribution part 217. Alternatively, the steam cover 33 is connected to the inlet and outlet concentrated distribution part 217 by threads. Alternatively, the steam cover 33 is connected to the inlet and outlet concentrated distribution part 217 by a fastener.

[0146] In order to optimize the design, as shown in Figure 9 、 Figures 12 to 15 , the cooking steam supply channel P12 is arranged inside the cooking steam discharge channel P11. The cooking steam inlet 203 is distributed on the side of the cooking steam outlet 202. In this way, the cooking steam supply channel P11 is contained inside the cooking steam discharge channel P12, occupying the space inside the cooking steam discharge channel P12, so that the two steam channels P1 occupy the same area inside the cover body, and the structure of the two steam channels P1 can be more compactly arranged, so that the internal space of the cover body occupies less space, which is beneficial to the miniaturization of the cover body and improves the utilization rate of the internal space. Moreover, the internal temperature of the cooking steam discharge channel P12 is relatively high, so that the cooking steam supply channel P11 can maintain a higher temperature, on the one hand, the steam entering the cooking cavity through the cooking steam supply channel P11 loses less heat, and the loss is less, so that the temperature of the cooking steam is higher, and the cooking effect is better; on the other hand, the steam entering the cooking cavity through the cooking steam supply channel P11 does not condense and liquefy, so as to avoid the influence of the water droplets mixed in the cooking steam on the cooking effect. The present scheme reduces the heat loss of the cooking steam during transmission, effectively ensures the best effect of moisture retention of food such as rice. Furthermore, the channel design defined in the present scheme enables the sealing of the two steam channels to be implemented in an inner and outer double sealing manner and to form an excellent sealing effect, thereby reducing the flow loss of the cooking steam during transmission.

[0147] A groove-shaped steam supply passage member 208 is arranged in the passage bottom shell 205. The groove wall of the steam supply passage member 208 is capable of abutting against the passage top plate 206 to form a steam supply passage P11. Specifically, the steam supply passage member 208 is arranged on the upper surface of the passage bottom shell 205 and inside the area defined by the outer peripheral portion of the passage bottom shell 205. The steam supply passage member 208 is connected to the passage bottom shell 205 by suitable means such as welding, clamping, fasteners such as screws, etc. The steam supply passage member 208 is capable of forming the steam supply passage P11 together with the passage top plate 206, i.e. the steam supply passage member 208 forms the bottom wall and the peripheral wall of the steam supply passage P11, and the passage top plate 206 forms the top wall of the steam supply passage P11. The present scheme uses a separate passage member on the passage bottom shell 205 to form the bottom wall and the peripheral wall of the steam supply passage P11, which can be easily arranged at a desired position on the passage bottom shell 205, reducing the number of parts and simplifying the structure.

[0148] To form a passage between the water container 41 and the cooking cavity, as shown in Figure 15 the passage bottom shell 205 is provided with a steam inlet column 231a which extends upward around the edge of the steam outlet 202 and penetrates through the steam supply passage member 208 to communicate with the steam supply passage P11. Specifically, as shown in Figure 12 and Figure 17 the steam supply passage member 208 is provided with a mounting hole 223 through which the steam inlet column 231a extends into the steam supply passage P11. The steam inlet column 231a is capable of communicating the steam supply passage P11 with the cooking cavity, and the lower end of the steam inlet column 231a forms the steam outlet 202, through which steam can flow from the steam supply passage P11 into the cooking cavity. The passage bottom shell 205 is further provided with a steam receiving column 231b which extends upward around the edge of the steam receiving port 201 and penetrates through the steam supply passage member 208 to communicate with the steam supply passage P11. Specifically, as shown in Figure 12 and Figure 17 the steam supply passage member 208 is further provided with another mounting hole 223 through which the steam receiving column 231b extends into the steam supply passage P11. The steam receiving column 231b is capable of communicating the steam supply passage P11 with the cooking cavity, and the lower end of the steam receiving column 231b forms the steam receiving port 201, through which steam can flow from the water container 41 into the steam supply passage P11.

[0149] The steam inlet column 231a and the steam receiving column 231b have communication holes 234 (see Figure 20), for steam flow. The steam inlet column 231a and steam receiving column 231b in this solution not only serve for steam flow, but also limit the movement of the cooking steam passage component 208 to fix the cooking steam passage component 208, serving two purposes, and the structure design is more optimal. The two mounting holes 223 of the cooking steam passage component 208 are respectively located at the two ends of the cooking steam passage component 208 in the length direction. Thus, the cooking steam passage component 208 receives steam at one end and outputs steam at the other end in the length direction. The size of the cooking steam passage component 208 can be designed to be smaller, so that the overall steam passage assembly 200 can be miniaturized.

[0150] In some examples, as in the illustrated example, the cooking steam passage component 208 is made of elastic sealing material and abuts against the passage top plate 206. In other words, the cooking steam passage component 208 is a part made of flexible material. Thus, the cooking steam passage component 208 is sealed against the passage top plate 206 to form an internal seal between the cooking steam passage component 208 and the passage top plate 206. The cooking steam passage component 208 itself has a sealing function and elastic deformation ability, and can be used as a sealing member, so it can also be called a passage sealing member. In this way, no additional sealing ring is needed to seal the gap between the cooking steam passage component 208 and the passage top plate 206. In addition, a seal is also formed between the cooking steam passage component 208 and the passage bottom shell 205, preventing steam from leaking out.

[0151] In the illustrated example, the cooking steam passage component 208 can be independently fixed to the passage bottom shell 205. No fixing plate for the sealing ring is needed, reducing the number of components, simplifying the structure and assembly process, and facilitating efficient use of the internal space of the cover body 3 and improving assembly efficiency. In an alternative example, a pressing plate is provided in the cooking steam passage component 208, which presses the bottom wall of the cooking steam passage component 208 against the passage bottom shell 205, and the side wall thereof forms most of the cooking steam supply passage P11 together with the pressing plate. The top of the side wall abuts against the lower bottom surface of the passage top plate 206, thereby constituting the entire cooking steam supply passage P11. The pressing plate is preferably made of rigid metal material that is not prone to rust, and near the cooking steam outlet, fasteners are used to connect the pressing plate, the bottom wall of the passage bottom shell, and the cover plate of the detachable cover assembly.

[0152] In some alternative unshown examples, the steam channel member 208 for the steam supply channel P11 is plate-shaped. The steam channel assembly 200 further comprises a steam channel seal member for the steam supply channel P11, which is arranged at the outer periphery of the steam channel member 208 and abuts against the channel top plate 206. The steam channel seal member is separately arranged to form the seal of the steam supply channel P11 for the steam supply channel P11, and the structure of the steam channel seal member can be simply designed to facilitate the production and manufacture of the steam channel seal member. The steam channel seal member for the steam supply channel P11 can be fixed to the channel bottom shell 205 through the steam channel member 208 for the steam supply channel P11. For example, the steam channel seal member for the steam supply channel P11 is a sealing ring with a lip, and the bottom of the sealing ring is clamped between the steam channel member 208 for the steam supply channel P11 and the channel bottom shell 205. In this scheme, the steam channel member 208 for the steam supply channel P11 serves as a pressing plate and can fix the steam channel seal member for the steam supply channel P11.

[0153] The specific structure of the cooking steam exhaust channel P12 is that the outer periphery of the channel bottom shell 205 is provided with a bottom shell outer periphery wall 241 extending upward, and the outer periphery of the channel top plate 206 is provided with a top plate outer periphery wall 242 extending downward. The bottom shell outer periphery wall 241 and the top plate outer periphery wall 242 are connected to each other to enclose the cooking steam exhaust channel P12. The part inside the outer periphery of the channel bottom shell 205 forms the bottom wall of the cooking steam exhaust channel P12, the part inside the outer periphery of the channel top plate 206 forms the top wall of the cooking steam exhaust channel P12, and the outer periphery walls of the two form the outer periphery wall of the cooking steam exhaust channel P12. In this way, the cooking steam exhaust channel P12 can occupy most of the inner cavity of the steam channel assembly 200, has a large volume, and a part of the volume can be used to accommodate the steam channel member 208 for the steam supply channel P11; and the steam channel assembly 200 as a whole can be miniaturized.

[0154] The cooking steam channel seal member 207 is arranged between the outer peripheries of the channel bottom shell 205 and the channel top plate 206 to form an outer seal. The cooking steam channel seal member 207 can be arranged on one of the bottom shell outer periphery wall 241 and the top plate outer periphery wall 242 and abut against the other of the bottom shell outer periphery wall 241 and the top plate outer periphery wall 242. The cooking steam channel seal member 207 is, for example, annular with a closed end. With the cooking steam channel seal member 207, a seal can be formed between the outer periphery walls of the channel bottom shell 205 and the channel top plate 206, so that steam is prevented from leaking out to the inside of the cover body, and the electrical components in the cover body are prevented from being damaged.

[0155] To better fix the cooking steam passage seal 207, the bottom shell peripheral wall 241 and the one of the top plate peripheral wall 242 are provided with a limiting groove 220 in which the cooking steam passage seal 207 is located. For example, the cooking steam passage seal 207 can be arranged on the top plate peripheral wall 242 and abut against the bottom shell peripheral wall 241; the top plate peripheral wall 242 is provided with the limiting groove 220 in which the cooking steam passage seal 207 is located. By arranging the limiting groove 220, the cooking steam passage seal 207 can be better fixed, and displacement of the cooking steam passage seal 207 due to deformation of the cooking steam passage seal 207 when the passage top plate 206 is covered to the passage bottom shell 205 is avoided, and the sealing effect is ensured.

[0156] The following will be described in combination with Figures 15 to 21 The example in which the cooking steam passage member 208 is made of elastic sealing material will be described in detail. In this example, the steam inlet column 231a and the steam receiving column 231b can be used as the mounting structure of the cooking steam passage member 208, and therefore they can also be referred to as the mounting column 231, or in other words, the mounting column 231 includes the steam inlet column 231a and the steam receiving column 231b.

[0157] The cooking steam passage member 208 includes a plate-shaped body 221 and a sealing portion 222 connected to the plate-shaped body 221. The plate-shaped body 221 is a basic part, and the sealing portion 222 is a deformed part. The plate-shaped body 221 is arranged on the upper surface of the passage top plate 206 in a flat manner, for example, and serves as the bottom of the cooking steam passage member 208 and is used to form the bottom wall of the steam passage P1. The lower surface of the plate-shaped body 221 can be attached to the upper surface of the passage bottom shell 205 to generate a friction force, so that displacement of the cooking steam passage member 208 due to deformation is avoided. The plate-shaped body 221 is detachably connected to the passage bottom shell 205, and the bottom of the cooking steam passage member 208 closer to the passage bottom shell 205 is detachable from the passage bottom shell 205. In this way, the connection structure can avoid the deformed part of the cooking steam passage member 208, and the connection structure does not affect the deformation of the cooking steam passage member 208, so that the sealing effect is better.

[0158] The sealing portion 222 is arranged around the periphery of the plate-shaped body 221 and extends toward the side where the passage top plate 206 is located to form the peripheral wall of the steam passage P1. The sealing portion 222 serves as the deformed part of the cooking steam passage member 208 and can abut against the passage top plate 206. The sealing portion 222 has a structure that is easy to deform, and for example, the sealing portion 222 has a lip that is attached to the passage top plate 206. In this way, the cooking steam passage member 208 can maintain good sealing performance with the passage top plate 206 even if it is disassembled and assembled multiple times. The shape of the lip can be V-shaped, Y-shaped, etc.

[0159] The plate-shaped body 221 is detachably and compactly sleeved on the mounting column 231 at the mounting hole 223; the outer surface of the mounting column 231 is tightly fitted with the inner surface of the mounting hole 223 to avoid steam leakage. The installation of the cooking steam passage component 208 is completed by directly sleeving the cooking steam passage component 208 on the mounting column 231, and other components for fixing the cooking steam passage component 208 are omitted; when the cooking steam passage component 208 needs to be detached, the cooking steam passage component 208 is detached from the mounting column 231; the installation and detachment process of the cooking steam passage component 208 is simple and easy to operate.

[0160] Optionally, as shown in Figure 20 and Figure 21 , the mounting column 231 is provided with a limiting buckle 232 extending radially outward from the outer circumferential surface of the mounting column 231. The plate-shaped body 221 includes a hole edge portion 224 forming the mounting hole 223, and the hole edge portion 224 is clamped on the lower side of the limiting buckle 232. The plate-shaped body 221 is clamped by the limiting buckle 232 to avoid the cooking steam passage component 208 from being detached from the mounting column 231, thereby improving the use safety of the cooking steam passage component 208. The radial dimension of the limiting buckle 232 is not too large, so that the cooking steam passage component 208 does not need to be too laborious when being detached. Optionally, the top surface of the limiting buckle 232 extends radially outward from the top surface of the mounting column 231. The top surface of the limiting buckle 232 is formed with an inclined or arc-shaped guide surface 233 to facilitate the hole edge portion 224 to be easily sleeved into the mounting column 231. Specifically, the guide surface 233 gradually extends downward in the radially outward direction. With the guide surface 233, the hole edge portion 224 slides along the guide surface 233 and deforms under force during assembly, and the hole edge portion 224 is easily sleeved into the mounting column 231. Each mounting column 231 is provided with at least one limiting buckle 232. The illustrated example schematically shows that each mounting column 231 is provided with two limiting buckles 232, and the two limiting buckles 232 are radially opposite.

[0161] Referring to Figure 19 , the passage bottom shell 205 is provided with a groove 235 recessed downward from the upper surface of the passage bottom shell 205 to form the downward protruding inlet and outlet concentrated distribution portion 217. The steam inlet column 231a extends upward from the bottom of the groove 235. The plate-shaped body 221 is provided with a sleeve 225 connected with the hole edge portion 224 (see Figure 18The sleeve 225 is sleeved on the steam inlet column 231a. In this way, the contact area between the sleeve 225 and the steam inlet column 231a is large, and the friction generated can limit the downward movement of the plate-shaped body 221, avoiding the influence of the partial downward movement of the plate-shaped body 221 on the sealing effect of the steam passage member 208.

[0162] Optionally, as shown in FIGS. 1 and 2, the upper surface of the passage bottom shell 205 is provided with a protruding rib 236 protruding upward, and the plate-shaped body 221 is located in the limiting area formed by the protruding rib 236. Figure 20 and Figure 21 By means of the protruding rib 236, the position of the plate-shaped body 221 on the passage bottom shell 205 can be limited, thus playing a role in positioning the steam passage member 208, avoiding the displacement of the steam passage member 208 relative to the passage bottom shell 205, thereby avoiding the influence of the local abnormal deformation of the steam passage member 208 on the sealing effect and preventing steam leakage. The protruding rib 236 is located on both sides of the steam passage member 208 and extends along the length direction of the steam passage member 208. The protruding rib 236 extends on the upper surface of the passage bottom shell 205. Optionally, the protruding rib 236 located on one side of the steam passage member 208 extends around the steam inlet column 231b and is connected with the protruding rib 236 located on the other side of the steam passage member 208. In this way, the steam inlet column 231b is located in the limiting area formed by the protruding rib 236. A part of the sealing portion 222 is clamped between the protruding rib 236 and the passage top plate 206. Further, the lip of the sealing portion 222 is clamped between the protruding rib 236 and the passage top plate 206. The sealing portion 222 has a large deformation at the protruding rib 236, which can improve the sealing effect of the steam passage member 208.
