[0024] According to the scheme, the steam docking cover for cooking can be detached from the cover body together with the detachable cover assembly, so that the steam docking cover for cooking can be cleaned to prevent the dirt on the steam docking cover for cooking from polluting the steam; the steam docking cover for cooking and the detachable cover assembly are detached in one step, and the detaching process is simple and efficient.

[0025] Optionally, the cover body comprises an inner liner, and the water container heating device comprises a fixing seat arranged on the upper portion of the heating component and fixed to the inner liner from the upper side of the inner liner, and the heating component has a wiring end which protrudes upward from the fixing seat.

[0026] According to the scheme, the inner liner can provide upward support force to the heating component and the connected fixing seat, so as to keep the heating component on the cover body; and the wiring end is on the upper side of the inner liner, which facilitates the connection between the wires inside the cover body and the wiring end.

[0027] Optionally, the cover body is pivoted about a pivot shaft between the closed position and the open position relative to the pot body, the pivot shaft is located at the rear end of the cover body, and the water container has a space for avoiding the heating component to enter or exit the water container with the pivoting of the cover body.

[0028] According to the scheme, the heating component does not interfere with the water container during the opening and closing of the cover body, and the position of the heating component extending into the water container does not affect the opening and closing of the cover body.

[0029] Optionally, the water container has a water container projection in a vertical plane, the heating component has a heating component projection in the vertical plane, and the pivot shaft has a pivot shaft projection in the vertical plane, the water container projection comprising a distal end inner wall projection distal to the pivot shaft projection.

[0030] The distal end inner wall projection has a first distance L1 to the center of the pivot shaft projection, and the heating component projection comprises a distal end point projection distal to the pivot shaft projection, the distal end point projection having a second distance L2 to the center of the pivot shaft projection, L2 < L1.

[0031] According to the present solution, the position of the heating component in the water container can be set based on the position of the pivot shaft, so as to ensure that the heating component does not interfere with the water container during the opening and closing of the cover.

[0032] Optionally, the water container is arranged at a corner of the pot body at the rear end, and the water container heating device is arranged at a corner of the cover body at the rear end.

[0033] According to the present solution, the space at the corner of the pot body and the cover body at the respective rear end is effectively utilized, so that the size of the pot body and the cover body can be avoided to be increased, and the miniaturization of the cooking appliance is facilitated.

[0034] Optionally, the cover body is connected to the pot body through a pivot shaft, one end of the cover body adjacent to the pivot shaft is a rear end portion, and the cooking appliance comprises a steam passage assembly, the steam passage assembly is arranged adjacent to the rear end portion and comprises a passage bottom shell and a passage top plate, the passage top plate is connected to the passage bottom shell and forms the cooking steam supply passage between the passage bottom shell and the passage top plate.

[0035] According to the present solution, the passage bottom shell and the passage top plate are independent components, and the steam passage is constructed by independent components such as the cover plate and the cover body, so that the steam passage can be manufactured by materials different from the cover plate and the cover body, and the components surrounding the steam passage are manufactured by food-grade materials, and the manufacturing cost is low. The area adjacent to the rear end portion of the cover body can be used to layout the steam passage assembly, so that the steam passage assembly occupies a relatively small cooking area of the cover body corresponding to the cooking cavity, and the cooking area of the cover body not occupied by the steam passage assembly is relatively large, and therefore the area can be designed in various ways.

[0036] The passage top plate and the passage bottom shell further form a cooking steam exhaust passage therebetween, and the cooking steam supply passage is located inside the cooking steam exhaust passage.

[0037] According to the scheme, the steam supply channel for the supplementary cooking can maintain a higher temperature, so that the steam for the supplementary cooking has a higher temperature and a better supplementary cooking effect. The steam for the supplementary cooking does not condense and liquefy when being transmitted in the steam supply channel for the supplementary cooking, so that the water droplets mixed in the steam for the supplementary cooking do not affect the supplementary cooking effect. The channel design defined by the scheme enables the sealing of the two steam channels to be implemented in an inner-outer double sealing manner and to form an excellent sealing effect, thereby reducing the flow loss of the steam for the supplementary cooking during the transmission process.

[0038] Alternatively, the steam supply channel for the supplementary cooking is located outside the cooking steam discharge channel. According to the scheme, the steam supply channel for the supplementary cooking and the cooking steam discharge channel are located in different areas of the steam channel assembly and are separated from each other, which facilitates the design of the structure and sealing of the two steam channels and increases the design freedom.

[0039] Optionally, the steam channel assembly further comprises a channel member for the steam for the supplementary cooking, which is connected to the channel bottom shell. The channel wall of the channel member for the steam for the supplementary cooking abuts against the channel top plate, thereby forming the steam supply channel for the supplementary cooking between the channel wall and the channel top plate.

The separate channel member can be easily arranged at a desired position on the channel bottom shell, thereby reducing the number of parts and simplifying the structure. The channel member for the steam for the supplementary cooking is independent of the channel bottom shell and can be made of a food-grade material, thereby avoiding the use of a food-grade material for the entire channel bottom shell and saving material costs.

[0041] Optionally, the channel member for the steam for the supplementary cooking is made of an elastic sealing material, so that the channel member for the steam for the supplementary cooking sealingly abuts against the channel top plate.

[0042] According to the scheme, the channel member for the steam for the supplementary cooking itself has a sealing function and an elastic deformation capability and can be used as a sealing member. In this way, a sealing ring is not needed to seal the gap between the channel member for the steam for the supplementary cooking and the channel top plate, thereby reducing the number of parts, simplifying the structure and assembly process, facilitating the effective use of the internal space of the cover body, and improving the assembly efficiency.

[0043] Alternatively, the steam channel assembly further comprises a sealing member for the steam for the supplementary cooking, which is arranged between the channel wall of the channel member for the steam for the supplementary cooking and the channel top plate.

[0044] According to the scheme, the channel member for the steam for the supplementary cooking, the channel top plate, and the channel sealing member surround the steam supply channel for the supplementary cooking.

[0088] As Figures 1 to 5As shown, the present application provides a cooking appliance 1, which includes a pot body 2 and a cover body 3. The pot body 2 has a cylindrical inner pot receiving portion. An inner pot 4 can be fixedly arranged in the inner pot receiving portion, or can be freely put into or taken out of the inner pot receiving portion for the convenience of cleaning the inner pot 4. The inner pot 4 is usually made of metal material and has a circular opening on the upper surface for containing materials to be heated, such as rice, soup, etc. The pot body 2 includes an inner pot heating device 5, such as a heating plate, for heating the inner pot 4. It can be understood that the cooking appliance 1 according to the present application can be an electric rice cooker, an electric pressure cooker or other cooking appliance 1, and the cooking appliance 1 can have various functions in addition to the function of cooking rice, such as cooking porridge, etc.

[0089] The cover body 3 has a shape substantially corresponding to that of the pot body 2. The cover body 3 is arranged on the pot body 2 in a pivotable manner. In one example, the cover body 3 is pivotally connected to the pot body 2 by a pivot shaft 6 and can be freely pivoted about a pivot axis of the pivot shaft 6 between a closed position and an open position relative to the pot body 2 for the convenience of closing and opening the pot body 2. In another example, the cover body 3 is connected to the pot body 2 by fasteners which cooperate with each other and are easy to disassemble, so that the two are tightly connected together during cooking, and are disassembled into two independent whole bodies during cleaning, for example. When the cover body 3 is closed on the pot body 2, it covers the inner pot 4 and forms a cooking cavity between the cover body 3 and the inner pot 4. The cover body 3 usually also has a pot opening sealing ring 7 made of rubber material, for example, which is arranged between the cover body 3 and the inner pot 4 for sealing the cooking cavity when the cover body 3 is in the closed state.

[0090] It should be noted that the directional terms used herein in describing various components, parts, etc. of the cooking appliance 1, such as "upper", "lower", "upper side", "lower side", "upward", "downward", "upwardly", "downwardly", etc. are relative to the cooking appliance 1 in a horizontal placement, upright state and with the cover body 3 in the closed state.

[0091] The cover body 3 basically includes a cover main body 8. The cover main body 8 includes an inner liner 9 and a face cover assembly 10. The face cover assembly 10 is arranged on the upper side or outer side of the inner liner 9 and can cover the inner liner 9. The upper surface of the face cover assembly 10 is provided with a user interaction area 11 for user operation. The inner liner 9 can be connected to the face cover assembly 10 by suitable means such as clamping, fastener connection such as screws, adhesion, etc. The pivot shaft 6 is arranged on the inner liner 9 and is sleeved with a torsional spring 12 for automatic opening of the cover.

[0092] The cover body 3 further comprises a detachable cover assembly 13. The detachable cover assembly 13 is located at the lower side of the cover main body 8 and is detachably connected to the cover main body 8 in the form of an assembly, so that the detachable cover assembly 13 is detachably mounted on the cover body 3 from the lower side. When the detachable cover assembly 13 needs to be cleaned, the detachable cover assembly 13 can be detached from the cover body 3. Specifically, the detachable cover assembly 13 is arranged at the lower side or inner side of the inner liner 9 and is detachably connected to the inner liner 9. For example, the detachable cover assembly 13 is movably connected to the inner liner 9 through a plug-in and / or clamping structure. The detachable cover assembly 13 substantially comprises a cover plate 14, a cover plate seat 15, and the aforementioned pot opening sealing ring 7. The cover plate 14 can be selected as a metal plate. At least part of the lower surface of the cover plate 14 forms the top surface of the cooking cavity. The cover plate seat 15 can detachably connect the cover plate 14 to the inner liner 9. The cover plate 14 can be connected to the cover plate seat 15 by other suitable means such as buckling or fastening. Part of the pot opening sealing ring 7 is pressed between the cover plate 14 and the cover plate seat 15.

[0093] The pot body 2 substantially comprises an outer shell 16, a middle plate 17 located at the upper side of the outer shell 16, and a base 18 located at the lower side of the outer shell 16. The lower end of the outer shell 16 can be connected to the outer periphery of the middle plate 17 by clamping, fastening by means such as screws, bonding, or other suitable means. The lower end of the outer shell 16 can be connected to the upper end of the base 18 by clamping, fastening by means such as screws, bonding, or other suitable means. The outer shell 16, the middle plate 17, and the base 18 together form an inner pot receiving portion. The inner pot heating device 5 can be arranged between the base 18 and the bottom of the inner pot 4 and connected to the base 18, so it is also called a bottom heating device. Alternatively, another inner pot heating device 5 can be arranged between the outer shell 16 and the side of the inner pot 4, so it is also called a side heating device. A power board can also be arranged in the pot body 2.

[0094] The cooking appliance 1 of the present application also has the function of steam cooking. High-temperature steam can be delivered into the cooking cavity to heat and moisten the food in the cooking cavity. For example, high-temperature steam can be delivered into the cooking cavity during the holding stage to keep the food such as rice moist and prevent the food from drying out and turning yellow. Specifically, the cooking appliance 1 further comprises a steam generating device 40 for generating cooking steam to cook the food in the cooking cavity. In order to deliver the cooking steam into the cooking cavity, the cover body 3 is provided with a cooking steam supply passage P11 that communicates with the cooking cavity. The cooking steam supply passage P11 is used for supplying the cooking steam for the cooking cavity, and specifically can receive the cooking steam from the steam generating device 40 and deliver the cooking steam into the cooking cavity.

[0095] The steam generating device 40 basically includes a water container 41 and a water container heating device 42. The water container 41 is disposed within the pot body 2 and is capable of storing water for generating supplementary cooking steam. Optionally, the water container 41 is located within a receiving cavity of the pot body 2, and its top protrudes from the upper surface of the pot body 2 to facilitate removal of the water container 41 from the pot body 2. The water container 41 has a top opening 43 for forming an outlet to allow supplementary cooking steam to escape. The water container heating device 42 is disposed on the cover 3 and is used to heat the water in the water container 41 to generate supplementary cooking steam.

[0096] The supplementary steam supply channel P11 connects the water container 41 to the cooking chamber to deliver supplementary steam to the cooking chamber. The supplementary steam can enter the supplementary steam supply channel P11 and then enter the cooking chamber to keep food such as rice in the inner pot 4 moist.

[0097] The water container 41 is located at the rear corner of the pot body 2, and the water container heating device 42 is located at the rear corner of the lid 3. This design effectively utilizes the space at the rear corners of the pot body 2 and the lid 3, thereby avoiding increasing the size of the pot body 2 and the lid 3, which is conducive to the miniaturization of the cooking appliance 1.

[0098] like Figure 2 , Figure 3 and Figure 5 As shown, the water container heating device 42 includes a heating element 44. The heating element 44 generates heat when powered on. The heating element 44 can be any suitable shape, such as tubular or sheet-like. In the illustrated example, the heating element 44 is a U-shaped tubular component. The heating element 44 extends downwards from the cover 3 and, when the cover 3 is in the closed position, extends into the water container 41 to heat the water in the water container 41 and generate supplementary steam. Since the heating element 44 is located inside the water container 41, the heat it generates can be directly absorbed by the water in the water container 41 without being conducted through the body of the water container 41. This improves heat utilization and heating efficiency, effectively reducing energy loss. Furthermore, it prevents heat transfer to components of the cooker body 2, such as the outer shell 16 and the power board, ensuring that the temperature of these components does not become too high. This avoids safety risks such as burns to the user at the outer shell 16 and ensures the normal operation of the power board, preventing damage to its components and improving product safety.

[0099] like Figure 7 As shown, the water container heating device 42 also includes a mounting base 46. The mounting base 46 is located above the heating element 44 and on the upper side of the liner 9. The mounting base 46 can be fixed to the liner 9. The mounting base 46 can be connected to the liner 9 by a suitable method such as welding or fastener connection such as screws. Exemplarily, the liner 9 is provided with screw posts 20 spaced apart (see...). Figure 6), the fixing seat 46 is provided with a lug 47 with a hole, and a screw is screwed into the screw column 20 through the lug 47. The inner liner 9 can provide upward supporting force to the heat generating component 44 and the connected fixing seat 46, so that the heat generating component 44 is kept on the cover body 3. The heat generating component 44 has a terminal 45 extending upward from the fixing seat 46. An electric wire can be connected to the terminal 45. The terminal 45 is on the upper side of the inner liner 9, facilitating the connection of the electric wire inside the cover body 3 to the terminal 45. In order to facilitate the installation of the heat generating component 44, as shown in Figure 4 and Figure 6 , the inner liner 9 is provided with a mounting hole 21, and the heat generating component 44 can pass through the inner liner 9 via the mounting hole 21.

[0100] The cover body 3 comprises a cooking steam docking cover 30. The cooking steam docking cover 30 covers the top opening 43 when the cover body 3 is in the closed position. The cooking steam docking cover 30 can close the top opening 43 of the water container 41 to prevent the cooking steam from overflowing. The cooking steam docking cover 30 is provided with a cooking steam inlet 32, which communicates the cooking steam supply channel P11 with the water container 41 to allow the steam to pass through. The steam can enter the cooking steam supply channel P11 of the cover body 3 from the cooking steam docking cover 30, facilitating the downward entry of the steam, and the flow structure of the steam is simple.

[0101] In order to facilitate the installation of the heat generating component 44, as shown in Figure 4 and Figure 5 , the cooking steam docking cover 30 is provided with an avoiding hole 33, and the heat generating component 44 extends downward through the avoiding hole 33. The heat generating component 44 passes through the cooking steam docking cover 30 through the avoiding hole 33, without affecting the opening and closing of the cooking steam docking cover 30.

[0102] As shown in Figure 7 , the water container heating device 42 further comprises a heat generating component sealing ring 48. As shown in Figure 4 , the heat generating component sealing ring 48 is located on the upper side of the cooking steam docking cover 30 and abuts against the upper surface of the cooking steam docking cover 30, specifically the edge of the avoiding hole 33. The upper part of the heat generating component 44 is arranged in the heat generating component sealing ring 48, so that the heat generating component sealing ring 48 can be in sealing contact with the outer surface of the upper part of the heat generating component 44. The shape of the heat generating component sealing ring 48 is matched with the outer contour shape of the heat generating component 44. In this way, the heat generating component sealing ring 48 can form a seal at the avoiding hole 33, preventing the cooking steam from overflowing to the inside of the cover body 3 through the avoiding hole 33, which can cause safety hazards due to the moisture of the live parts and the connection position inside the cover body 3, and improve the safety of the product.

[0103] The heat component sealing ring 48 can be fixed to the inner liner 9, for example, the heat component sealing ring 48 is inserted into the mounting hole 21 and is clamped to the edge of the mounting hole 21 from the upper side of the mounting hole 21. The heat component sealing ring 48 can abut against the lower surface of the fixing seat 46, so that the inner liner 9 provides an upward supporting force to the heat component sealing ring 48, and the heat component sealing ring 48 provides an upward supporting force to the fixing seat 46 connected to the heat component 44. The heat component sealing ring 48 can be mounted to the mounting hole 21 from the lower side of the mounting hole 21, so as to be mounted on the inner liner 9, and the mounting structure is simple and the mounting steps are easy to operate.

[0104] The cover seat 15 comprises a plate-shaped seat support portion 22 protruding from the rear portion of the cover plate 14. The steam docking cover 30 for cooking supplement is arranged on the seat support portion 22. Optionally, the steam docking cover 30 for cooking supplement is integrally formed with the seat support portion 22. Alternatively, the steam docking cover 30 for cooking supplement is a separate component from the cover seat 15, which can be connected to the seat support portion 22 by suitable means such as welding, fasteners such as screws, etc. The steam docking cover 30 for cooking supplement can be detached from the cover body 3 together with the detachable cover assembly 13, so that the steam docking cover 30 for cooking supplement can be cleaned to prevent dirt on the steam docking cover 30 for cooking supplement from contaminating the steam. The steam docking cover 30 for cooking supplement and the detachable cover assembly 13 are detached in one step, and the detachment process is simple and efficient.

[0105] The steam docking cover 30 for cooking supplement is also provided with a steam docking sealing member 31 for cooking supplement, which forms a seal between the water container 41 and the steam docking cover 30 for cooking supplement when the cover body 3 is closed. The steam docking sealing member 31 for cooking supplement abuts against the top of the water container 41 for forming the top opening 43 when the cover body 3 is in the closed position. With the help of the steam docking sealing member 31 for cooking supplement, a seal can be formed between the steam docking cover 30 for cooking supplement and the top of the water container 41, preventing the cooking steam from overflowing from the gap between them, and improving the utilization rate of the cooking steam.

[0106] As Figure 8 and Figure 9As shown, the pivot shaft 6 is located at the rear end of the cover 3, and the water container 41 has a space for the heating element 44 to enter or exit the water container 41 as the cover 3 pivots. The heating element 44 does not interfere with the water container 41 during the opening and closing of the cover 3, and the position of the heating element 44 extending into the water container 41 does not affect the opening and closing of the cover 3. The water container 41 has a distal end inner wall 61 distal to the pivot shaft 6, and the heating element 44 has a distal end point 62 distal to the pivot shaft 6. The water container 41 has a water container projection in a vertical plane, the heating element 44 has a heating element projection in the vertical plane, and the pivot shaft 6 has a pivot shaft projection in the vertical plane. The water container projection includes a distal end inner wall projection distal to the pivot shaft projection. The distal end inner wall projection has a first distance L1 to the center of the pivot shaft projection, and the heating element projection includes a distal end point projection distal to the pivot shaft projection. The distal end point projection has a second distance L2 to the center of the pivot shaft projection, and L2 < L1. The position of the heating element 44 in the water container 41 can be set based on the position of the pivot shaft 6 to ensure that the heating element 44 does not interfere with the water container 41 during the opening and closing of the cover 3.

[0107] When the cooking appliance 1 is cooking, heating the food and water in the inner pot 4 will generate cooking steam. In order to exhaust the cooking steam to the outside environment, the cover 3 is also provided with a cooking steam exhaust passage P12 (see Figure 2 ) and an exhaust passage, and the steam in the cooking cavity can first enter the cooking steam exhaust passage P12 and then be exhausted to the outside environment through the exhaust passage.

[0108] In order to simplify the structure and optimize the use of space in the cover 3, the present application uses one component to jointly form the cooking steam supply passage P11 and the cooking steam exhaust passage P12, rather than using different components to form the two passages. Specifically, the cover 3 further includes a steam passage assembly 50 for forming the cooking steam supply passage P11 and the cooking steam exhaust passage P12. The two passages are independent of each other and not connected. The steam passage assembly 50 is located on the upper side of the cover plate 14 and the lower side of the inner liner 9. As shown, the inner liner 9 has a recess 19 for accommodating the steam passage assembly 50. At least part of the steam passage assembly 50 is accommodated in the recess 19. The size and shape of the recess 19 are adapted to the outer contour of the steam passage assembly 50. Figure 3

[0109] The end of the cover 3 adjacent to the pivot shaft 6 is the rear end, and the steam passage assembly is arranged adjacent to the rear end. The area of the cover adjacent to the rear end can be used to layout the steam passage assembly, so that the steam passage assembly occupies a relatively small cooking area of the cover corresponding to the cooking cavity, and the cooking area of the cover not occupied by the steam passage assembly is relatively large, so that the area can be designed in various ways.

[0110] ​In some examples, as shown in the illustrated example, the supplementary cooking steam supply passage P11 is located outside the cooking steam exhaust passage. The supplementary cooking steam supply passage P11 and the cooking steam exhaust passage are separated from each other in different regions within the steam passage assembly, and are designed separately in terms of structure and sealing, so that the design freedom is large. In some alternative examples, the supplementary cooking steam supply passage P11 is located inside the cooking steam exhaust passage. The supplementary cooking steam supply passage P11 is contained inside the cooking steam exhaust passage, so that the supplementary cooking steam supply passage P11 can maintain a higher temperature, so that the temperature of the supplementary cooking steam is higher, and the supplementary cooking effect is better; the steam entering the cooking cavity for supplementary cooking does not condense and liquefy in the supplementary cooking steam supply passage P11, so that the water droplets mixed in the supplementary cooking steam do not affect the supplementary cooking effect. The channel design defined by this scheme allows the sealing of the two steam passages to be constructed in an inner-outer double-sealing manner and to form an excellent sealing effect, reducing the flow loss of the supplementary cooking steam during transmission.

[0111] As shown in Figure 3 Figure 4 and Figure 5 , the steam passage assembly 50 is also provided with a steam receiving port 51 communicating with the supplementary cooking steam supply passage P11 and a supplementary cooking steam outlet 52. The steam receiving port 51 is used to receive steam from the steam generating device 40, and the supplementary cooking steam outlet 52 is used to communicate the supplementary cooking steam supply passage P11 with the cooking cavity.

[0112] The steam passage assembly 50 is also provided with a cooking steam inlet 53 communicating with the cooking steam exhaust passage P12 and an exhaust port. The cooking steam inlet 53 is used to communicate the cooking steam exhaust passage P12 with the cooking cavity, and the exhaust port is used to exhaust the steam in the cooking steam exhaust passage P12. The cover body 8 is provided with the above-mentioned exhaust passage. The position of the exhaust port corresponds to the exhaust passage of the cover body 8.

[0113] Referring back to Figure 2 and Figure 4 , the steam passage assembly 50 includes a passage bottom shell 54 and a passage top plate 55. The passage top plate 55 is located on the upper side of the passage bottom shell 54 and can be covered to the passage bottom shell 54. The outer periphery profiles of the passage bottom shell 54 and the passage top plate 55 correspond in shape and size, and the outer periphery profiles of the passage bottom shell 54 and the passage top plate 55 are shown schematically as being substantially triangular in shape.

[0114] The cooking steam supply passage P11 and the cooking steam exhaust passage P12 are formed between the channel bottom shell 54 and the channel top plate 55. Further, the two steam passages are partly formed by the channel bottom shell 54 or the components thereon, and partly formed by the channel top plate 55 or the components thereon. The steam passage assembly 50 comprises two channel sealing members, i.e. the cooking steam supply passage sealing member and the cooking steam exhaust passage sealing member 56, for forming a seal at the cooking steam supply passage P11 and the cooking steam exhaust passage P12 respectively. For example, the cooking steam supply passage P11 and the cooking steam exhaust passage P12 are arranged at different regions of the channel bottom shell 54. In this example, the channel bottom shell 54 forms the bottom wall of the two steam passages, so that the channel bottom shell 54 and the channel top plate 55 enclose the two steam passages. For another example, the channel bottom shell 54 is provided with a pressing plate 57 (see Fig. 6), which is used to form the bottom wall of the two steam passages; in this solution, the pressing plate 57 can be used to fix the channel sealing members, which are connected to the channel top plate 55. Thus, the pressing plate 57, the channel sealing members and the channel top plate 55 enclose the two steam passages. Figure 2

[0115] For another example, the steam passage assembly 50 further comprises a cooking steam passage member 58 in the form of a groove, which is arranged between the channel bottom shell 54 and the channel top plate 55. The cooking steam passage member 58 is connected to the channel bottom shell 54. The groove wall of the cooking steam passage member 58 abuts against the channel top plate 55, so that the cooking steam supply passage P11 is formed between the two. Optionally, the cooking steam passage member 58 is made of elastic sealing material. Thus, the cooking steam passage member 58 is sealingly abutted against the channel top plate 55 to form a seal therebetween. The cooking steam passage member 58 itself has the functions of sealing and elastic deformation, and can be used as a sealing member, so it can also be referred to as a channel sealing member. In this way, no additional sealing ring is needed to seal the gap between the cooking steam passage member 58 and the channel top plate 55, which reduces the number of components, simplifies the structure and assembly process, and is conducive to the effective use of the internal space of the cover body 3 and the improvement of assembly efficiency.

[0116] ​Alternatively, a steam channel seal is provided between the channel wall of the steam channel member 58 and the channel top plate 55 to form a seal between the steam channel member 58 and the channel top plate 55. The cooking steam channel seal 56 is provided between both the channel bottom shell 54 and the channel top plate 55. The cooking steam channel seal 56 is compressed against the channel bottom shell 54 by the compression plate 57. The cover plate 14, which forms the top wall of the cooking cavity, needs to be made of food grade material. The channel bottom shell 54 and the channel top plate 55 are separate components and can be made of different material from the cover plate 14. The components used to enclose the steam channels, such as the channel bottom shell 54, the channel top plate 55, the compression plate 57 and / or the steam channel member 58 for the cooking steam channel are also made of food grade material. With this design, the top wall of the steam channel can be formed without the cover body 8, so that the cover body 8 does not need to be made of food grade material, thereby saving material cost.

[0117] The steam channel assembly 50 is at least partially mounted on the removable lid assembly 13, so that the steam channel assembly 50 is at least partially removed from the lid body 3 together with the removable lid assembly 13 for cleaning of the two steam channels on the steam channel assembly 50. For the illustrated example, at least the channel bottom shell 54 is mounted on the removable lid assembly 13, so that at least the channel bottom shell 54 is removed from the lid body 3 together with the removable lid assembly 13. In particular, the channel bottom shell 54 is connected with the removable lid assembly 13 to be removed from or mounted to the lid body 3 together with the removable lid assembly 13. As a result, at least the channel bottom shell 54 can be removed from the lid body 3 for cleaning of the two steam channels. The channel top plate 55 can be separated from the channel bottom shell 54 to expose the interior of the steam channels for better cleaning of the interior of the steam channels. The channel bottom shell 54 can be connected to the seat support 22 by channel welding, fasteners such as screws or suitable means.

[0118] For the illustrated example, the channel top plate 55 is connected with the cover body 8. The channel top plate 55 is latched to the channel bottom shell 54 without fixed connection therebetween. When cleaning of the steam channels is required, the whole of the channel bottom shell 54 and the removable lid assembly 13 can be removed from the lid body 3. This exposes part of the steam channels on the channel top plate 55 and part of the steam channels on the channel bottom shell 54. The channel bottom shell 54 and the removable lid assembly 13 removed from the lid body 3 can be cleaned by the user with water, and the channel top plate 55 remaining on the lid body 3 can be cleaned by the user by wiping. In this arrangement, the channel top plate 55 is latched to the channel bottom shell 54 on the removable lid assembly 13 when the removable lid assembly 13 is mounted to the lid body 3 to form a closed steam channel.
