[0120] 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 to facilitate closing and opening of the pot body 2. In another example, the cover body 3 is connected to the pot body 2 by fasteners that 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 with the inner pot 4. The cover body 3 also usually has a pot opening sealing ring 7 made of, for example, rubber material, which is arranged between the cover body 3 and the inner pot 4 to seal the cooking cavity when the cover body 3 is in the closed state.

[0121] It should be noted that the directional terms used herein to describe 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 a closed state.

[0122] The cover body 3 substantially 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 torsion spring 12 to automatically open the cover. The pot body 2 also includes an open cover button, and the cover body 3 is provided with an open cover mechanism. By pressing the open cover button, the open cover mechanism is unlocked. One end of the cover body 3 provided with the open cover mechanism or adjacent to the open cover button is the front end, and the reverse end of the front end is the rear end. Generally, the rear end of the cover body 2 is adjacent to the pivot shaft 6 of the cover body 2 and the pot body 2.

[0123] In one example, 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 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 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 basically 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.

[0124] In another alternative example, the cover body 3 comprises the aforementioned cover plate 14, which is fixedly connected to the cover main body 8, specifically to the inner liner 9, so that the cover plate 14 is non-detachably mounted on the cover body 3.

[0125] The pot body 2 basically 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. Alternatively, another inner pot heating device 5 can be arranged between the outer shell 16 and the side of the inner pot 4.

[0126] The cooking appliance 1 of the present application also has the function of top heat radiation heating, the heat generated by the top heat source can be radiated to the food in the cooking cavity to heat the food from the top side. Specifically, the cover body 3 comprises a top heating device 100 located in the area corresponding to the inner pot 4 of the cover body 3, which can transmit heat to the cooking cavity by heat radiation. The top heating device 100 can be any suitable heating device such as an electric heating device, an electromagnetic heating device or an infrared heating device. The electric heating device can be an electric heating tube, an electric heating wire, an electric heating film or any suitable electric heating device. 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.

[0127] 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.

[0128] 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

[0129] During cooking, 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 cooking utensil 1 is provided with a cooking steam exhaust passage P2. Figure 5 As shown, the cover body 3 is further provided with a cooking steam exhaust passage P12 and an exhaust passage P2 for the steam exhausted from the cooking cavity to pass through, the cooking steam exhaust passage P12 being in communication with the cooking cavity and the exhaust passage P2 being 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.

[0130] For the infrared heating device, one example is that the infrared heating device can be an infrared electric heating tube. For example, the infrared electric heating tube is formed by encapsulating the infrared heating element in a glass 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 electrified. 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 heat generated by the heating assembly 120 can be transferred to the radiation plate 110, and the radiation plate 110 can radiate infrared rays to the cooking cavity after being heated. The radiation plate 110 can be a ceramic plate, a carbon plate made of carbon material, or the like. 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.

[0131] The structure of the cover body 3 is further described by taking the example shown in the drawings as an example. As shown, Figure 3 Figure 7 ​​As shown, the inner liner 9 has an inner liner through-hole 20, and the radiating plate 110 is installed at the inner liner through-hole 20. The cover plate 14 is located below the radiating 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 radiating plate 110. In other words, the cover plate through-hole 21 is located directly below the radiating plate 110. The infrared rays generated by the radiating plate 110 can radiate towards the inner pot 4 through the inner liner through-hole 20 and the cover plate through-hole 21.

[0132] like Figure 6 and Figure 7 As shown, the inner liner 9 may be provided with a support portion 22. The support portion 22 is disposed around the through hole 20 of the inner liner, and the support portion 22 forms a closed annular structure. The outer edge of the radiant plate 110 can overlap 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 an upward supporting force to the radiant plate 110 and restrict the horizontal movement of the radiant plate 110, facilitating the fixation of the radiant plate 110. In one example, the support portion 22 can be recessed downward, and the radiant plate 110 is accommodated in the recessed support portion 22. In another example, the support portion 22 is a planar structure, i.e., it does not form a recess. A peripheral sealing ring 130 is fitted around the outer periphery of the radiant plate 110 to form a seal between the radiant plate 110 and the inner liner 9. The top heating device 100 also includes a fixing member 140. The fixing member 140 can be connected to the inner liner 9, and the outer edge of the radiant plate 110 is sandwiched between the fixing member 140 and the support portion 22. The fastener 140 may optionally be configured as a ring, which can be connected to the liner 9 by a suitable means such as snap-fit, fastener connection such as screws, welding, etc.

[0133] Additionally, the cover 3 may also include a through-hole sealing ring 23. The through-hole sealing ring 23 can be disposed around the periphery of the through-hole 21 of the cover plate and located on the side opposite to the side where the pot opening sealing ring 7 is located, specifically between the radiant plate 110 and the inner liner 9, abutting against the lower surface of the radiant plate 110. Forming a seal at the through-hole 21 of the cover plate prevents steam from entering the interior of the cover 3 through the gap between the radiant plate 110 and the cover plate 14, thereby improving the sealing effect of the cover 3. For example, a pressure ring 24 can be provided to clamp a portion of the through-hole sealing ring 23 between the pressure ring 24 and the cover plate 14, and the pressure ring 24 can be fixed to the cover plate 14 by a bendable clip.

[0134] 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. Here, the steam passage P1 includes the above-mentioned cooking steam supply passage P11 and / or the cooking steam exhaust passage P12. Alternatively, the cover plate 14 can also be provided with a protruding portion 25, and the protruding portions 25 of the cover plate 14 and the inner liner 9 correspond in position.

[0135] In order to simplify the structure and optimize the use of the space in the cover body 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 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 arranged in parallel with the top heating device 100 in the horizontal direction, specifically on 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.

[0136] 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.

[0137] 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.

[0138] 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.

[0139] 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.

[0140] Another example is shown in FIG. 6, in which the cooking steam supply passage P11 is arranged inside the cooking steam discharge passage P12 (to be described in detail below). In this example, the passage bottom shell 205 forms the bottom wall of the cooking steam discharge passage P12, so that the passage bottom shell 205 and the passage top plate 206 enclose the cooking steam discharge passage P12. The steam passage assembly 200 further includes a cooking steam passage member 208 arranged between the passage bottom shell 205 and the passage top plate 206 for forming the cooking steam supply passage P11. Figure 9

[0141] In the example described above in which the passage bottom shell 205 forms the bottom wall of the steam passage P1, the passage bottom shell 205 is provided with a passage wall 209 extending upward from the upper surface of the passage bottom shell 205, which encloses the peripheral side wall of the steam passage P1.

[0142] The cover plate 14 needs to be made of food-grade material as it forms the top wall of the cooking cavity. The passage bottom shell 205 and the passage top plate 206 are independent components and can be made of different materials from the cover plate 14. The components used to enclose the steam passage P1, such as the passage bottom shell 205, the passage top plate 206, the pressing plate, and / or the cooking steam passage member 208, are also made of food-grade material. In this way, the top wall of the steam passage P1 can be formed without using the cover body 8, so that the cover body 8 does not need to be made of food-grade material, thereby saving material costs.

[0143] The steam passage assembly 200 is at least partially mounted on the detachable cover assembly 13, so that the steam passage assembly 200 is at least partially detached from the cover body 3 together with the detachable cover assembly 13 for cleaning the two steam passages P1 on the steam passage assembly 200. The cover plate through hole 21 is arranged adjacent to the front end portion 36a of the detachable cover assembly 13. The steam passage 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 passage assembly 200 can be arranged in front and back order, with the cover plate through hole 21 in front and the steam passage 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 by 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 passage assembly 200 is arranged at a region outside the cover plate through hole 21.

[0144] ​For the illustrated example, at least the channel bottom shell 205 is mounted on the removable lid assembly 13, so that at least the channel bottom shell 205 is removed from the lid body 3 together with the removable lid assembly 13. In particular, the channel bottom shell 205 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. Thus, at least the channel bottom shell 205 can be removed from the lid body 3 for cleaning the two steam channels PI. The channel top plate 206 can be separated from the channel bottom shell 205 to expose the inside of the steam channels PI for better cleaning of the inside of the steam channels PI.

[0145] For the illustrated example, the channel top plate 206 is detachably connected with the channel bottom shell 205 to be removed from or mounted to the lid body 3 together with the channel bottom shell 205. When it is necessary to clean the steam channels PI, the whole of the steam channel assembly 200 and the removable lid assembly 13 can be removed from the lid body 3, and then the channel top plate 206 can be removed from the channel bottom shell 205. In this way, part of the steam channels PI on the channel top plate 206 is exposed, and part of the steam channels PI on the channel bottom shell 205 is also exposed. The removable lid assembly 13 and the channel bottom shell 205 removed from the lid body 3 can be cleaned by the user with water, and the channel top plate 206 removed from the lid body 3 can be cleaned by the user with water separately. The user can easily clean the steam channels PI, and the cleaning effect is good.

[0146] Alternatively, the channel top plate 206 is connected with the lid body 8. The channel top plate 206 covers the channel bottom shell 205, and the two can be connected without fixation. When it is necessary to clean the steam channels PI, the whole of the channel bottom shell 205 and the removable lid assembly 13 can be removed from the lid body 3. In this way, part of the steam channels PI on the channel top plate 206 is exposed, and part of the steam channels PI on the channel bottom shell 205 is also exposed. The removable lid assembly 13 and the channel bottom shell 205 removed from the lid body 3 can be cleaned by the user with water, and the channel top plate 206 kept on the lid body 3 can be cleaned by the user with wiping. In this solution, the channel top plate 206 is butted against the channel bottom shell 205 on the removable lid assembly 13 when the removable lid assembly 13 is mounted to the lid body 3 to form the closed steam channels PI.

[0147] 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.

[0148] 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 cooking steam. 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.

[0149] The configuration of the steam channel assembly 200 will be further described below with reference to the example shown in the figure.

[0150] 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 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.

[0151] The steam supply passage P11 for the steam supply to the cooking vessel is provided with a steam outlet 202 at one end and a steam inlet 201 at the other end. In other words, the steam inlet 201 and the steam outlet 202 are located at the two ends of the steam supply passage P11 for the steam supply to the cooking vessel. Alternatively, the steam supply passage P11 for the steam supply to the cooking vessel is a straight passage with a center line extending in the front-to-rear direction of the cover plate 14 at a preset angle. Further, the steam supply passage P11 for the steam supply to the cooking vessel is inclined relative to the longitudinal center line of the cover plate 14. It should be noted that, in the example of the detachable cover assembly 13, the longitudinal center lines of the cover plate 14 and the detachable cover assembly 13 are collinear.

[0152] It should be noted that, as used herein, the term "longitudinal" or "longitudinal direction" refers to the front-to-rear direction, and the term "lateral" or "lateral direction" refers to the left-to-right direction.

[0153] As shown in FIG. 1, the steam passage assembly 200 is arranged on the cover plate 14 of the detachable cover assembly 13. The steam passage assembly 200 includes a channel base 205 and a cover plate seat 15. The channel base 205 is arranged on the cover plate 14 of the detachable cover assembly 13. The channel base 205 is provided with a steam supply passage P11 for the steam supply to the cooking vessel. The steam supply passage P11 for the steam supply to the cooking vessel is provided with a steam outlet 202 at one end and a steam inlet 201 at the other end. In other words, the steam inlet 201 and the steam outlet 202 are located at the two ends of the steam supply passage P11 for the steam supply to the cooking vessel. Alternatively, the steam supply passage P11 for the steam supply to the cooking vessel is a straight passage with a center line extending in the front-to-rear direction of the cover plate 14 at a preset angle. Further, the steam supply passage P11 for the steam supply to the cooking vessel is inclined relative to the longitudinal center line of the cover plate 14. It should be noted that, in the example of the detachable cover assembly 13, the longitudinal center lines of the cover plate 14 and the detachable cover assembly 13 are collinear.

The steam passage assembly 200 includes a channel base 205 and a cover plate seat 15. The channel base 205 is arranged on the cover plate 14 of the detachable cover assembly 13. The channel base 205 is provided with a steam supply passage P11 for the steam supply to the cooking vessel. The steam supply passage P11 for the steam supply to the cooking vessel is provided with a steam outlet 202 at one end and a steam inlet 201 at the other end. In other words, the steam inlet 201 and the steam outlet 202 are located at the two ends of the steam supply passage P11 for the steam supply to the cooking vessel. Alternatively, the steam supply passage P11 for the steam supply to the cooking vessel is a straight passage with a center line extending in the front-to-rear direction of the cover plate 14 at a preset angle. Further, the steam supply passage P11 for the steam supply to the cooking vessel is inclined relative to the longitudinal center line of the cover plate 14. It should be noted that, in the example of the detachable cover assembly 13, the longitudinal center lines of the cover plate 14 and the detachable cover assembly 13 are collinear. Figure 13 As shown in FIG. 1, the steam passage assembly 200 is arranged on the cover plate 14 of the detachable cover assembly 13. The steam passage assembly 200 includes a channel base 205 and a cover plate seat 15. The channel base 205 is arranged on the cover plate 14 of the detachable cover assembly 13. The channel base 205 is provided with a steam supply passage P11 for the steam supply to the cooking vessel. The steam supply passage P11 for the steam supply to the cooking vessel is provided with a steam outlet 202 at one end and a steam inlet 201 at the other end. In other words, the steam inlet 201 and the steam outlet 202 are located at the two ends of the steam supply passage P11 for the steam supply to the cooking vessel. Alternatively, the steam supply passage P11 for the steam supply to the cooking vessel is a straight passage with a center line extending in the front-to-rear direction of the cover plate 14 at a preset angle. Further, the steam supply passage P11 for the steam supply to the cooking vessel is inclined relative to the longitudinal center line of the cover plate 14. It should be noted that, in the example of the detachable cover assembly 13, the longitudinal center lines of the cover plate 14 and the detachable cover assembly 13 are collinear.

[0154] The channel top plate 206 can be detachably connected to the channel bottom shell 205 through a snap structure. The snap structure includes a fixed snap 212 and a movable snap 213, which correspond to different side edges of the steam channel assembly 200 respectively. The fixed snap 212 is connected to the channel bottom shell 205 and is provided with a snap opening 214. The movable snap 213 is rotatably connected to the seat support part 29. The channel top plate 206 is provided with a first protruding buckle 215 matched with the fixed snap 212 and a second protruding buckle 216 matched with the movable snap 213. The first protruding buckle 215 can be buckled into the snap opening 214 of the fixed snap 212, and the second protruding buckle 216 can be buckled by the movable snap 213 from the upper side. The seat support part 29 is provided with a column protruding upward at intervals, and the movable snap 213 is rotatably connected to the column. When assembled, the first protruding buckle 215 is buckled into the snap opening 214 of the fixed snap 212 first to realize the fixation of one side edge of the assembly, and then the movable snap 213 is rotated to be buckled to the second protruding buckle 216 to realize the fixation of the other side edge of the assembly. When disassembled, the movable snap 213 is unlocked first, and then the fixed snap 212 is separated.

[0155] The area near the rear end portion 36b of the cover plate 14 is provided with an inlet and outlet concentrated distribution area R of the steam channel assembly 200, Figure 11 and Figure 13 The approximate position and shape of the inlet and outlet concentrated distribution area R are shown by a dashed line. The inlet and outlet concentrated distribution area R is provided with the cooking steam outlet 202 and the cooking steam inlet 203. As shown in the example, the channel bottom shell 205 is provided with the inlet and outlet concentrated distribution area R, which is arranged in the area near the rear end portion 36b of the cover plate 14. This design ingeniously concentrates the cooking steam outlet 202 and the cooking steam inlet in a relatively small area, and does not need to arrange a sealing member and a sealing structure at two ports respectively, which simplifies the manufacturing and assembly process and also makes the structure more simple. The inlet and outlet concentrated distribution area R is arranged at the front end portion of the channel bottom shell 205 in the longitudinal direction.

[0156] Alternatively, the area of the cover plate 14 adjacent to the rear end portion 36b is connected with a steam cover 33. The steam cover 33 is provided with openings corresponding to the cooking steam outlet 202 and the cooking steam inlet 203. For example, the steam cover 33 is annular, and the openings are annular. Alternatively, the steam cover 33 is provided with openings corresponding to the cooking steam outlet 202 and the cooking steam inlet 203, respectively. The steam cover 33 can be made of different materials or individually designed according to the needs of the user. Different components of the detachable cover assembly 13 are designed according to the functions to be performed and the effects to be achieved. The surface of the cover plate is required to be made of food-grade stainless steel as it serves as the top surface of the cooking cavity. In addition, the surface is also the visible surface after the cooking appliance is opened. Therefore, the openings for the cooking steam and the cooking steam are designed in a relatively small area of the visible surface, which can improve the user's visual experience in terms of structural design. Alternatively, the cover plate 14 is provided with openings corresponding to the cooking steam outlet 202 and the cooking steam inlet 203 in the area R. For example, the cover plate 14 is provided with a steam cover passing hole 32 (i.e., an opening), and the steam cover 217 described below is combined with the steam cover passing hole 32. Alternatively, the cover plate 14 is provided with openings corresponding to the cooking steam outlet 202 and the cooking steam inlet 203, respectively. The steam cover 217 described below abuts against the portion of the cover plate 14 having the two openings.

[0157] Specifically, the channel bottom shell 205 includes a steam cover portion 217 protruding downward, and the steam cover portion 217 is provided with a steam cover opening 218 for connecting the steam passage P1 with the cooking cavity. The steam cover opening 218 includes a cooking steam outlet 202 communicating with the cooking steam supply passage P11 and / or a cooking steam inlet 203 communicating with the cooking steam exhaust passage P12. That is, the cooking steam outlet 202 and / or the cooking steam inlet 203 are provided on the steam cover portion 217. For example, the area R is provided on the steam cover portion 217, so that the cooking steam outlet 202 and the cooking steam inlet 203 are provided on the steam cover portion 217. The cover plate 14 is provided with a steam cover passing hole 32, and the steam cover portion 217 is combined with the steam cover passing hole 32.

[0158] The channel bottom shell 205 can be closer to the cover plate 14 at the steam cover portion 217 protruding downward, and the steam cover portion 217 is limited in the steam cover passing hole 32. On the one hand, the steam cover opening 218 on the steam cover portion 217 can be connected with the cooking cavity. On the other hand, the cover plate 14 limits the horizontal position of the channel bottom shell 205 at the steam cover portion 217, so as to avoid the horizontal movement of the channel bottom shell 205 relative to the cover plate 14.

[0159] Exemplarily, the steam passing portion 217 is a flange-shaped protruding portion which extends into or through the steam passing hole 32. The flange surface can abut against the edge of the steam passing hole 32, and the protruding portion can be limited within the steam passing hole 32. This assembly structure enables the steam passing portion to be stably retained on the cover plate.

[0160] The steam passing 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 longer extension path, so as to miniaturize the steam passage assembly 200 in the longitudinal direction, and thus the part of the steam passage assembly on the cover plate 14 is smaller in size and occupies a smaller area ratio. The steam passing portion 217 is configured to be adapted to the steam passing hole 32 in shape and size. The structure between the steam passing 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.

[0161] The steam passing cover 33 is located on both sides of the cover plate 14, and the steam passing cover 33 is located on the lower side of the cover plate 14 to fix the steam passing portion 217 to the cover plate 14. The detachable cover assembly 13 further comprises a steam passing area sealing member 34. The steam passing area sealing member 34 is arranged between one of the steam passing cover 33 and the steam passing portion 217 and the edge of the steam passing hole 32. For example, as shown in the example, the steam passing area sealing member 34 is arranged between the cover plate 14 and the steam passing portion 217 to form a seal therebetween. The steam passing portion 217 is located within the steam passing hole 32 and connected to the steam passing cover 33, the edge of the steam passing hole 32 can be clamped between the steam passing portion 217 and the steam passing cover 33, and the steam passing area sealing member 34 is clamped between the cover plate 14 and the steam passing portion 217. Alternatively, the steam passing cover 33 is welded to the steam passing portion 217. Alternatively, the steam passing cover 33 is connected to the steam passing portion 217 by threading.

[0162] One of the prominent optimization improvements of the present application is that the cooking steam supply passage P11 is arranged inside the cooking steam discharge passage P12.

[0163] As described above, the steam passage assembly 200 is formed with the cooking steam supply passage P11 for the steam for cooking the cooking cavity to pass through and the cooking steam discharge passage P12 for the steam discharged from the cooking cavity to pass through. In order to optimize the design, as shown in the example, Figure 9 、 Figures 12 to 15 the cooking steam supply passage P11 is arranged inside the cooking steam discharge passage P12.

[0164] In this way, the cooking steam supply passage P11 is contained in the cooking steam discharge passage P12, and occupies the space inside the cooking steam discharge passage P12, so that the two steam passages P1 occupy the same area in the cover body, and the structure of the two steam passages P1 can be more compactly arranged, so that the internal space in the cover body 3 is small, 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 passage P12 is relatively high, so that the cooking steam supply passage P11 can maintain a higher temperature, on the one hand, the steam entering the cooking cavity for cooking has less heat loss when passing through the cooking steam supply passage P11, 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 for cooking is not condensed and liquefied in the cooking steam supply passage P11, so that the water droplets mixed in the cooking steam do not affect the cooking effect. The present scheme reduces the heat loss of the cooking steam in the transmission process, effectively ensures that the moisture of food such as rice reaches the best effect. Furthermore, the passage design defined in the present scheme enables the sealing of the two steam passages to be constructed in an inner and outer double sealing manner and to form excellent sealing effect, thereby reducing the flow loss of the cooking steam in the transmission process.

[0165] As described above, the cooking steam supply passage P11 can be formed by the cooking steam passage member 208. Specifically, the cooking steam passage member 208 is arranged on the passage bottom shell 205 and located within the area defined by the outer peripheral portion of the passage bottom shell 205. The cooking steam passage member 208 is connected to the passage bottom shell 205 by suitable means such as welding, clamping, fastening by screws or the like. The cooking steam passage member 208 can be surrounded by the passage top plate 206 to form the cooking steam supply passage P11, so that the cooking steam passage member 208 forms at least the bottom wall of the cooking steam supply passage P11, and the passage top plate 206 forms at least the top wall of the cooking steam supply passage P11. The present scheme uses an independent passage member on the passage bottom shell 205 to form the bottom part of the cooking steam supply passage P11, which can be easily arranged at the desired position on the passage bottom shell 205, and the sealing structure between the independent passage member and the passage top plate 206 can also be easily constructed.

[0166] In order 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 is arranged around the edge of the cooking steam outlet 202 and extends upward by a certain height, and the cooking steam inlet 203 is arranged beside the steam inlet column 231a. The steam inlet column 231a can separate the cooking steam outlet 202 from the cooking steam discharge passage P12, so as to avoid the cooking steam from leaking into the cooking steam discharge passage at the outlet thereof.

[0167] The steam inlet column 231a passes through the supplementary cooking steam passage component 208 to communicate with the supplementary cooking steam supply passage P11. Specifically, as shown... Figure 12 and Figure 17 As shown, the supplementary cooking steam passage component 208 is provided with a mounting hole 223, through which the steam inlet column 231a can extend into the supplementary cooking steam supply passage P11. The steam inlet column 231a can connect the supplementary cooking steam supply passage P11 with the cooking chamber. The lower end of the steam inlet column 231a is formed as the supplementary cooking steam outlet 202, and steam can flow from the supplementary cooking steam supply passage P11 into the cooking chamber through the steam inlet column 231a.

[0168] The bottom shell 205 of the channel is also provided with a steam receiving column 231b. The steam receiving column 231b is arranged around the edge of the steam receiving port 201 and extends upward to a certain height. The steam receiving column 231b can separate the steam receiving port 201 from the cooking steam exhaust channel P12, preventing the supplementary cooking steam from leaking into the cooking steam exhaust channel P12 at its steam receiving port 201. The steam receiving column 231b passes through the supplementary cooking steam channel component 208 to communicate with the supplementary cooking steam supply channel P11. Specifically, as shown... Figure 12 and Figure 17 As shown, the supplementary cooking steam passage component 208 is also provided with another mounting hole 223, through which the steam receiving column 231b can extend into the supplementary cooking steam supply passage P11. The steam receiving column 231b can connect the supplementary cooking steam supply passage P11 with the cooking chamber. The lower end of the steam receiving column 231b is formed as a steam inlet 201, and steam can flow from the water container 41 into the supplementary cooking steam supply passage P11 through the steam receiving column 231b.

[0169] The steam inlet column 231a and the steam outlet column 231b have a connecting hole 234 (see Figure 20 The steam inlet column 231a and steam outlet column 231b in this design are used for steam circulation. They not only facilitate steam circulation but also restrict the movement of the supplementary cooking steam passage component 208 to fix it in place, serving a dual purpose and resulting in a superior structural design. The two mounting holes 223 of the supplementary cooking steam passage component 208 are located at opposite ends of its length. Thus, the supplementary cooking steam passage component 208 receives steam at one end and outputs steam at the other. The size of the supplementary cooking steam passage component 208 can be designed to be smaller, thereby miniaturizing the overall steam passage assembly 200.

[0170] In some examples, as shown in the illustrated example, the steam supply channel member 208 is made of elastic sealing material and abuts against the channel top plate 206. In other words, the steam supply channel member 208 is a part made of flexible material. The steam supply channel member 208 thus seals against the channel top plate 206 to form a seal between the steam supply channel member 208 and the channel top plate 206. The steam supply channel member 208 itself has the functions of sealing and elastic deformation and can be used as a sealing member, and thus 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 steam supply channel member 208 and the channel top plate 206. In addition, a seal is also formed between the steam supply channel member 208 and the channel bottom shell 205, so that steam leakage is avoided.

[0171] In the illustrated example, the steam supply channel member 208 can be independently fixed to the channel bottom shell 205. No pressing plate for fixing the sealing ring is needed, which reduces the number of components, simplifies the structure and assembly process, and is conducive to efficient use of the internal space of the cover 3 and improvement of assembly efficiency. In alternative examples, a pressing plate is provided in the steam supply channel member 208, the pressing plate presses the bottom wall of the steam supply channel member 208 against the channel bottom shell 205, and the side peripheral wall of the steam supply channel member 208 together with the pressing plate forms most of the steam supply channel P11, the top of the side peripheral wall abuts against the lower bottom surface of the channel top plate 206, thereby forming the entire steam supply channel. The pressing plate is preferably made of rigid metal material that is not prone to rust, and fasteners are used to connect the pressing plate, the bottom wall of the channel bottom shell, and the cover plate of the detachable cover assembly near the steam supply outlet.

[0172] In some alternative examples not shown, the steam channel assembly 200 further comprises a steam supply channel sealing member provided on the outer periphery of the steam supply channel member 208 and abutting against the channel top plate 206. The channel sealing member is separately provided to form a seal of the steam supply channel P11, and the structure of the steam supply channel sealing member can be simply designed to facilitate production and manufacture of the steam supply channel sealing member. The steam supply channel sealing member can be fixed to the channel bottom shell 205 by the steam supply channel member 208, for example, the steam supply channel sealing member is a sealing ring with a lip, and the bottom of the sealing ring is clamped between the steam supply channel member 208 and the channel bottom shell 205. In this scheme, the steam supply channel member 208 serves as a pressing plate and can fix the steam supply channel sealing member.

[0173] In some alternative examples, a steam supply channel member that can independently form a steam supply channel is provided in the steam channel assembly. For example, the steam supply channel member can be formed by a tubular member such as a rubber tube, or by a separate channel.

[0174] The specific structure of the cooking steam discharging passage P12 is that the outer peripheral portion of the passage bottom shell 205 is provided with a bottom shell outer peripheral wall 241 extending upward, and the outer peripheral portion of the passage top plate 206 is provided with a top plate outer peripheral wall 242 extending downward. The bottom shell outer peripheral wall 241 and the top plate outer peripheral wall 242 are connected to each other to form the cooking steam discharging passage P12. The portion inside the outer peripheral portion of the passage bottom shell 205 forms the bottom wall of the cooking steam discharging passage P12, the portion inside the outer peripheral portion of the passage top plate 206 forms the top wall of the cooking steam discharging passage P12, and the outer peripheral walls of the two form the outer peripheral wall of the cooking steam discharging passage P12. In this way, the cooking steam discharging passage P12 can occupy most of the inner cavity of the steam passage assembly 200, has a large volume, and part of the volume can be used to accommodate the cooking steam supplementing passage member 208; and the steam passage assembly 200 as a whole can be miniaturized.

[0175] The passage sealing member 207 can be arranged on one of the bottom shell outer peripheral wall 241 and the top plate outer peripheral wall 242 and abut against the other of the bottom shell outer peripheral wall 241 and the top plate outer peripheral wall 242. The passage sealing member 207 is, for example, an annular member with a tail end abutting against each other. With the passage sealing member 207, a seal can be formed between the outer peripheral walls of the passage bottom shell 205 and the passage 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.

[0176] In order to better fix the passage sealing member 207, the one of the bottom shell outer peripheral wall 241 and the top plate outer peripheral wall 242 is provided with a limiting groove 220, and the passage sealing member 207 is located in the limiting groove 220. For example, the passage sealing member 207 can be arranged on the top plate outer peripheral wall 242 and abut against the bottom shell outer peripheral wall 241; the top plate outer peripheral wall 242 is provided with the limiting groove 220, and the passage sealing member 207 is located in the limiting groove 220 of the passage top plate 206. By providing the limiting groove 220, the passage sealing member 207 can be better fixed, so that the passage sealing member 207 is prevented from being displaced due to its own deformation when the passage top plate 206 is covered to the passage bottom shell 205, and the sealing effect is ensured.

[0177] The following will be described in combination with Figures 15 to 21 The specific example that the cooking steam supplementing passage member 208 is made of elastic sealing material will be described. 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 supplementing passage member 208, and therefore they can also be referred to as mounting columns 231, or in other words, the mounting columns 231 include the steam inlet column 231a and the steam receiving column 231b.

[0178] The steam passage component 208 for cooking includes a plate-shaped body 221 and a sealing part 222 connected to the plate-shaped body 221. The plate-shaped body 221 is a basic part, and the sealing part 222 is a deformable part. The plate-shaped body 221 is arranged on the upper surface of the passage top plate 206 in a flat manner, and the plate-shaped body 221 is the bottom of the steam passage component 208 for cooking 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 friction and prevent the steam passage component 208 for cooking from moving due to deformation. The plate-shaped body 221 is detachably connected to the passage bottom shell 205, and the part of the steam passage component 208 for cooking closer to the passage bottom shell 205 is detachable from the passage bottom shell 205. The connection structure can avoid the deformation of the steam passage component 208 for cooking, and the connection structure does not affect the deformation of the steam passage component 208 for cooking, so that the sealing effect is better.

[0179] The sealing part 222 is arranged around the periphery of the plate-shaped body 221 and extends towards the side where the passage top plate 206 is located to form the peripheral wall of the steam passage P1. The sealing part 222 is a deformable part of the steam passage component 208 for cooking and can abut against the passage top plate 206. The sealing part 222 has a structure that is easy to deform, and the sealing part 222 has a lip that is attached to the passage top plate 206, for example. In this way, the steam passage component 208 for cooking can maintain good sealing performance with the passage top plate 206 even after being disassembled multiple times. The shape of the lip can be V-shaped, Y-shaped, etc.

[0180] 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 attached to the inner surface of the mounting hole 223 to prevent steam leakage. By directly sleeving the steam passage component 208 for cooking on the mounting column 231, the installation of the steam passage component 208 for cooking can be completed, and other components for fixing the steam passage component 208 for cooking are not needed; when the steam passage component 208 for cooking needs to be disassembled, the steam passage component 208 for cooking can be detached from the mounting column 231; the installation and disassembly process of the steam passage component 208 for cooking is simple and easy to operate.

[0181] Optionally, as Figure 20 and Figure 21As shown, the mounting post 231 is provided with a limiting buckle 232 extending radially outward from the outer circumferential surface of the mounting post 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 at the lower side of the limiting buckle 232. By means of the limiting buckle 232, the plate-shaped body 221 is clamped to avoid the steam passage member 208 from being detached from the mounting post 231, and the use safety of the steam passage member 208 is improved. The radial dimension of the limiting buckle 232 is not too large, so that the steam passage member 208 does not need to be too laborious when disassembled. Optionally, the top surface of the limiting buckle 232 extends radially outward from the top surface of the mounting post 231. The top surface of the limiting buckle 232 is formed with an inclined or arc-shaped guide surface 233, so that the hole edge portion 224 is easily sleeved into the mounting post 231. Specifically, the guide surface 233 gradually extends downward in the radially outward direction. By means of the guide surface 233, the hole edge portion 224 slides along the guide surface 233 and deforms under force when assembled, and the hole edge portion 224 is easily sleeved into the mounting post 231. Each mounting post 231 is provided with at least one limiting buckle 232. The illustrated example schematically shows that there are two limiting buckles 232 on each mounting post 231, and the two limiting buckles 232 are radially opposite.

[0182] 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, so as to form the steam passage portion 217 protruding downward. The steam inlet post 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 18 ), and the sleeve 225 is sleeved on the steam inlet post 231a. In this way, the contact area between the sleeve 225 and the steam inlet post 231a is large, and the friction generated can limit the downward movement of the plate-shaped body 221, so as to avoid the steam passage member 208 from affecting the sealing effect due to the partial downward movement of the plate-shaped body 221. The steam inlet post 231a includes a circumferential fixing surface 237 and a downward-facing bottom limiting surface 238, and the sleeve 225 is sleeved on the circumferential fixing surface 237 and abuts against the bottom limiting surface 238. Optionally, the steam inlet post 231a is radially outwardly protruded at the bottom to form a boss, and the upper surface of the boss is the bottom limiting surface 238. The bottom limiting surface 238 can limit the downward movement of the sleeve 225, and further avoid the steam passage member 208 from affecting the sealing effect due to the partial downward movement of the plate-shaped body 221.

[0183] Optionally, as Figure 20 and Figure 21As shown, the upper surface of the channel bottom shell 205 is provided with a convex rib 236 protruding upward, and the plate-shaped body 221 is located in the limiting area formed by the convex rib 236. By means of the convex rib 236, the position of the plate-shaped body 221 on the channel bottom shell 205 can be limited, thus playing a role in positioning the cooking steam channel component 208, avoiding displacement of the cooking steam channel component 208 relative to the channel bottom shell 205, and thus avoiding the cooking steam channel component 208 from affecting the sealing effect due to local abnormal deformation, preventing steam leakage. The convex rib 236 is located on both sides of the cooking steam channel component 208 and extends along the length direction of the cooking steam channel component 208. The convex rib 236 extends on the upper surface of the channel bottom shell 205. Optionally, the convex rib 236 located on one side of the cooking steam channel component 208 extends around the steam receiving column 231b and is connected with the convex rib 236 located on the other side of the cooking steam channel component 208. Thus, the steam receiving column 231b is located in the limiting area formed by the convex rib 236. A part of the sealing portion 222 is clamped between the convex rib 236 and the channel top plate 206. Further, the lip of the sealing portion 222 is clamped between the convex rib 236 and the channel top plate 206. The sealing portion 222 has greater deformation at the convex rib 236, which can improve the sealing effect of the cooking steam channel component 208.
