The cover plate 14 can be connected to the cover plate seat 15 through other suitable means such as buckles or fasteners. Part of the pot opening sealing ring 7 is pressed between the cover plate 14 and the cover plate seat 15.

[0113] In another alternative example, the cover body 3 comprises the aforementioned cover plate 14, which is located at the bottom side of the cover body 3 and 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.

[0114] 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 through clamping, fastening by means of fasteners such as screws, adhesion or other suitable means. The lower end of the outer shell 16 can be connected to the upper end of the base 18 through clamping, fastening by means of fasteners such as screws, adhesion 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.

[0115] The cooking appliance 1 also has a function of top heat radiation heating, and 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, which is located in the region of the cover body 3 corresponding to the inner pot 4, and the heat generated by the top heating device 100 can be transmitted to the cooking cavity in the form of 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 or an electric heating film. The electromagnetic heating device comprises an electromagnetic coil and a coil disc, and 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, and the alternating magnetic field generated by the electromagnetic coil can act on the metal cover plate 14 below to heat the cover plate 14 itself to radiate heat to the cooking cavity. The illustrated example schematically 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 exciting the aroma of the food.

[0116] The cooking appliance 1 also has a function of steam cooking, and 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 delivered to the cooking cavity during the heat preservation stage, which can keep the food such as rice moist, and avoid 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 which communicates with the cooking cavity. The cooking steam supply channel 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 to the cooking cavity.

[0117] The steam generating device 40 can be arranged in the cover body 3 or the pot body 2. Figure 2 An example in which the steam generating device 40 is arranged in the pot body 2 is schematically shown. For example, the steam generating device 40 basically comprises a water container and a water container heating device. The water container is arranged in the pot body 2 and can store water for generating cooking steam. Optionally, the water container is located in the accommodating 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 from the pot body 2. The water container has a top opening for forming an outlet to allow the cooking steam to overflow. The water container heating device is usually arranged below the water container and is used for heating the water in the water container to generate the cooking steam. The cooking steam can enter the cooking steam supply channel 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 and the water container heating device are different from the foregoing example.

[0118] When cooking, the food and water in the inner pot 4 of the cooking appliance 1 generate cooking steam. To vent this cooking steam to the outside environment, such as... Figure 3 and Figure 4 As shown, the cover 3 is also provided with a cooking steam exhaust channel P12 and a cooking steam external exhaust channel P2 for the passage of steam discharged from the cooking chamber. The cooking steam exhaust channel P12 is connected to the cooking chamber and the cooking steam external exhaust channel P2 are connected. The cooking steam can first enter the cooking steam exhaust channel P12 and then be discharged to the external environment through the cooking steam external exhaust channel P2.

[0119] For an infrared heating device, one example is that the device includes an infrared heating tube and a light-transmitting insulating plate. For instance, an infrared heating element is encapsulated within a glass tube to form the infrared heating tube, with the insulating plate disposed below the infrared heating tube. An alternative example is that the infrared heating tube can be replaced by an electrically conductive heating film disposed on a plate-like member, in which case the plate-like member for arranging the heating film is at least partially light-transmitting. The infrared heating device also includes a reflective member 111 to reflect upwardly radiated infrared light into the cooking cavity, thereby improving heating efficiency.

[0120] Another alternative example is an infrared heating device comprising a radiant plate and a heating assembly 120 for heating the radiant plate, the heating assembly 120 being located above the radiant plate. Heat generated by the heating assembly 120 is transferred to the radiant plate, which, when heated, radiates infrared rays into the cooking cavity. The radiant plate can be a ceramic plate, a carbon plate made of carbon material, etc. The radiant plate is exposed inside the cooking cavity, and at least a portion of its lower surface forms the top surface of the cooking cavity. The temperature of the radiant plate can be controlled by controlling the power or heating temperature of the heating assembly 120.

[0121] Using the illustrated example, the structure of cover 3 will be further described. For example... Figure 4 As shown, the inner liner 9 has an inner liner through-hole 20, and the partition plate 110 is installed at the inner liner through-hole 20. The cover plate 14 is disposed below the partition 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 partition plate 110. In other words, the cover plate through-hole 21 is located directly below the partition plate 110. Infrared rays generated by the partition plate 110 can be radiated toward the inner pot 4 through the inner liner through-hole 20 and the cover plate through-hole 21. Alternatively, the cover plate 14 may be at least partially transparent. The cover plate 14 may be made entirely of a transparent material such as glass, or the portion corresponding to the partition plate 110 may be made of a transparent material.

[0122] The inner liner 9 can be provided with a support portion 22. The support portion 22 is arranged around the inner liner through hole 20, and forms a closed annular structure. The outer edge of the isolation plate 110 can be lapped on the bottom wall of the support portion 22 and abut against the side wall of the support portion 22. The support portion 22 can provide upward support force to the isolation plate 110, and limit the movement of the isolation plate 110 in the horizontal direction, facilitating the fixation of the isolation plate 110. In one example, the support portion 22 can be concave downward, and the isolation plate 110 is accommodated in the concave support portion 22. In another example, the support portion 22 is a planar structure, i.e. not concave. The outer peripheral portion of the isolation plate 110 is sleeved with a peripheral sealing ring 130 to form a seal between the isolation plate 110 and the inner liner 9. The top heating device 100 further comprises a fixing member 140. The fixing member 140 can be connected with the inner liner 9, and the outer edge of the isolation plate 110 is clamped between the fixing member 140 and the support portion 22. The fixing member 140 is optionally arranged in an annular shape, which can be connected with the inner liner 9 by clamping, fastening by fasteners such as screws, welding or other suitable methods.

[0123] In addition, the cover body 3 can further comprise a through hole sealing ring 23. The through hole sealing ring 23 can be arranged on the peripheral portion of the cover plate through hole 21 and located on the side opposite to the side where the pot opening sealing ring 7 is located, specifically, located between the isolation plate 110 and the inner liner 9, and abuts against the lower surface of the isolation plate 110. Forming a seal at the cover plate through hole 21 can avoid steam entering the inside of the cover body 3 through the gap between the isolation plate 110 and the cover plate 14, thereby improving the sealing effect of the cover body 3. For example, a compression ring 24 can be arranged to clamp a part of the through hole sealing ring 23 between the compression ring 24 and the cover plate 14, and the compression ring 24 can be fixed with the cover plate 14 by bendable clamping corners.

[0124] In order to simplify the structure and optimize the utilization of the space in the cover body 3, the utility model uses one component to jointly form the cooking steam supply passage P11 and the cooking steam discharge passage P12, rather than using different components to form the two passages respectively. Specifically, referring to Figures 7 to 10 , the cover body 3 further comprises a steam passage assembly 200 for forming the cooking steam supply passage P11 and the cooking steam discharge 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. The steam passage assembly 200 is located on one side of the top heating device 100, specifically, the rear side of the top heating device 100. As shown in Figure 4 and Figure 5 , 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 concave upward from the lower surface of the inner liner 9. The steam passage assembly 200 is accommodated in the recess 26.

[0125] Please refer to Figure 8The steam passage assembly 200 is further provided with a steam inlet 201 and a steam outlet 202 which are in communication with the steam supply passage P11. The steam inlet 201 is configured to receive steam from the steam generator 40, and the steam outlet 202 is configured to communicate the steam supply passage P11 with the cooking cavity. The steam inlet 201 is located above the water container 41. Figure 11 and Figure 12 The steam flow path is schematically indicated by arrows. In particular, steam generated by heating water in the water container 41 enters the steam supply passage P11 via the steam inlet 201, flows along the steam supply passage P11, and exits the steam supply passage P11 via the steam outlet 202 into the cooking cavity.

[0126] Referring to Figure 8 and Figure 13 The steam passage assembly 200 is further provided with a steam inlet 203 and a steam outlet 204 which are in communication with the steam exhaust passage P12. The steam inlet 203 is configured to communicate the steam exhaust passage P12 with the cooking cavity, and the steam outlet 204 is configured to exhaust steam from the steam exhaust passage P12. The lid body 8 is provided with the steam exhaust passage P2. The steam outlet 204 is located above the steam exhaust passage P2 of the lid body 8. Referring back to Figure 3 and Figure 4 The lid body 3 further comprises a steam passage structure forming the steam exhaust passage P2, which can comprise a steam valve 27 and a steam seal 28 which are vertically arranged in the lid body 8. Figure 13 The steam flow path is schematically indicated by arrows. In particular, steam in the cooking cavity enters the steam exhaust passage P12 via the steam inlet 203, flows along the steam exhaust passage P12, and exits the steam exhaust passage P12 via the steam outlet 204 into the steam exhaust passage P2, and then to the ambient environment.

[0127] Referring back to Figure 9 The steam passage assembly 200 comprises a passage bottom shell 205 and a passage top plate 206. The passage top plate 206 is located below the passage bottom shell 205 and can be coupled to the passage bottom shell 205. The steam seal 28 abuts against an 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. The outer periphery of the passage bottom shell 205 and the passage top plate 206 is schematically shown as a substantially rounded rectangular strip.

[0128] The bottom shell 205 is connected to the top plate 206, forming a supplementary steam supply passage P11 and a cooking steam exhaust passage P12 between them. Specifically, a portion of these two steam passages P1 is formed by the bottom shell 205 or components thereon, while another portion is formed by the top plate 206 and components thereon. The steam passage assembly 200 includes two passage seals, namely a supplementary steam passage seal and a cooking steam passage seal 207, used to form seals at the supplementary steam supply passage P11 and the cooking steam exhaust passage P12, respectively. As an example, the supplementary steam supply passage P11 and the cooking steam exhaust passage P12 are located in different areas of the bottom shell 205. In this example, the bottom shell 205 forms the bottom wall of these two steam passages P1, and the two passage seals are clamped at different locations on the passage walls, thereby the bottom shell 205 and the top plate 206 enclose these two steam passages P1.

[0129] Another example is, such as Figure 9 As shown, the supplementary steam supply passage P11 is located inside the cooking steam exhaust passage P12. In this example, the bottom shell 205 forms the bottom wall and outer peripheral wall 209 of the cooking steam exhaust passage P12. The bottom shell 205 and the top plate 206 are connected at their outer peripheries to form the cooking steam exhaust passage P12. A cooking steam passage seal 207 is located between the outer peripheries of the bottom shell 205 and the top plate 206, thereby forming a sealed cooking steam exhaust passage P12. The steam passage assembly 200 also includes a supplementary steam passage component 208, which is located between the bottom shell 205 and the top plate 206 to form the supplementary steam supply passage P11. The supplementary steam passage component 208 is located on the bottom shell 205 and within the area defined by the outer periphery of the bottom shell 205.

[0130] At least the bottom shell 205 of the steam channel assembly 200 is mounted on the removable cover assembly 13, or in other words, the steam channel assembly 200 is part of the removable cover assembly 13. Thus, the steam channel assembly 200 is at least partially removed from the cover 3 along with the removable cover assembly 13, allowing for cleaning of the two steam channels P1 on the steam channel assembly 200. The cover through-hole 21 is located near the front end 46a of the removable cover assembly 13. The steam channel assembly 200 is located near the rear end 46b of the removable cover assembly 13. The cover through-hole 21 and the steam channel assembly 200 can be arranged front and rear, with the cover through-hole 21 in front and the steam channel assembly 200 in the rear, allowing the cover through-hole 21 to be designed to occupy a larger cooking area. The cover 14 defines a cooking area within the pot opening sealing ring 7, and the cover through-hole 21 is located within this cooking area and occupies an area greater than 3 / 5 of the cooking area, for example, 8 / 10, 4 / 5, etc. The steam passage assembly 200 is located in the area outside the cover plate through hole 21.

[0131] The channel top plate 206 is separable from the channel bottom shell 205 to expose the interior of the steam channel P1 for better cleaning of the interior of the steam channel P1. In the illustrated example, the channel top plate 206 is detachably connected to the channel bottom shell 205 to be detached from or mounted to the cover body 3 together with the channel bottom shell 205. When cleaning of the steam channel P1 is required, the whole of the steam channel assembly 200 and the detachable cover assembly 13 can be detached from the cover body 3, and then the channel top plate 206 is detached from the channel bottom shell 205. This exposes part of the steam channel P1 on the channel top plate 206 and part of the steam channel P1 on the channel bottom shell 205. The detachable cover assembly 13 and the channel bottom shell 205 detached from the cover body 3 can be cleaned by the user with water, and the channel top plate 206 detached from the cover body 3 can be cleaned by the user with water separately. The user can easily clean the steam channel P1 with good cleaning effect.

[0132] Alternatively, the channel top plate 206 is connected to the cover body 8. The channel top plate 206 covers the channel bottom shell 205 without fixed connection therebetween. When cleaning of the steam channel P1 is required, the whole of the channel bottom shell 205 and the detachable cover assembly 13 can be detached from the cover body 3. This exposes part of the steam channel P1 on the channel top plate 206 and part of the steam channel P1 on the channel bottom shell 205. The detachable cover assembly 13 and the channel bottom shell 205 detached from the cover body 3 can be cleaned by the user with water, and the channel top plate 206 remaining on the cover body 3 can be cleaned by the user with wiping. In this scheme, the channel top plate 206 is butted against the channel bottom shell 205 on the detachable cover assembly 13 when the detachable cover assembly 13 is mounted to the cover body 3 to form the enclosed steam channel P1.

[0133] The channel bottom shell 205 is provided with the above-mentioned cooking steam outlet 203 and the cooking steam inlet 203. The channel top plate 206 is provided with the cooking steam outlet 204. The cooking steam outlet 204 is located at least partially in a region corresponding to the position of the cooking steam inlet 203. In other examples not shown, the cover plate 14 can be provided with the above-mentioned cooking steam outlet 203 and the cooking steam inlet 203, and the channel bottom shell 205 is provided with a channel structure at positions corresponding to the cooking steam inlet 201 and the cooking steam outlet 202. The channel structure is sandwiched with a sealing member between the cover plate 14. In the illustrated example where the steam generating device 40 is arranged in the pot body 2, the channel bottom shell 205 is provided with the above-mentioned cooking steam inlet 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 cooking steam inlet 201 to admit steam from the upper side.

[0134] Referring to Figure 13The cover body 3 also includes a cooking steam temperature measuring device 50 for detecting the temperature of cooking steam. The cooking steam temperature measuring device 50 is located on the cover body 8 and includes a cooking steam temperature measuring element 51. The cooking steam temperature measuring element 51 extends into the cooking steam exhaust channel P12. The cover body 3 also includes a supplementary cooking steam temperature measuring device 52 for detecting the temperature of supplementary cooking steam. The supplementary cooking steam temperature measuring device 52 is located on the cover body 8 and includes a supplementary cooking steam temperature measuring element 53. The supplementary cooking steam temperature measuring element 53 extends into the cooking supplementary cooking steam supply channel P11 through a temperature measuring hole 219 in the channel top plate 206.

[0135] The construction of the steam channel assembly 200 is further described below using the illustrated example.

[0136] like Figures 6 to 10 As shown, the steam passage assembly 200 spans across the same side of the cover plate 14 and the cover plate seat 15. The passage bottom shell 205 extends beyond the rear of the cover plate 14 in both the longitudinal and transverse directions on the horizontal plane. The steam passage assembly 200 is inclined relative to the longitudinal centerline of the removable cover assembly 13. The supplementary cooking steam inlet 201 is located at the rear end 210 of the passage bottom shell 205, and this rear end 210 is located at the rear corner of the cover plate seat. The steam generator 40 is located at the rear corner of the pot body 2, and the rear end 210 of the passage bottom shell 205 corresponds to the corner of the cover body 3. This allows the position of the supplementary cooking steam inlet 201 to correspond vertically with the water container 41 of the steam generator 40, and steam enters the supplementary cooking steam inlet 201 from bottom to top, making the steam path between the supplementary cooking steam inlet 201 and the water container 41 shorter and more direct. At least the supplementary cooking steam outlet 202 is located at the front end 211 of the passage bottom shell 205, and this front end 211 is located at the rear end of the cover plate. In the illustrated example, both the supplementary steam outlet 202 and the cooking steam inlet 203 are located at the front end 211 of the channel bottom shell 205. The cooking steam inlet 203 is distributed around the supplementary steam outlet 202.

[0137] The supplementary cooking steam supply channel P11 has a supplementary cooking steam outlet 202 at one end and a supplementary cooking steam inlet 201 at the other end. In other words, the supplementary cooking steam inlet 201 and the supplementary cooking steam outlet 202 are located at opposite ends of the supplementary cooking steam supply channel P11. Optionally, the supplementary cooking steam supply channel P11 is a straight channel. Furthermore, the supplementary cooking steam supply channel P11 is inclined relative to the longitudinal centerline of the cover plate 14. It should be noted that in the example of the removable cover assembly 13, the longitudinal centerlines of the cover plate 14 and the removable cover assembly 13 are collinear. It should be noted that the terms "longitudinal" and "longitudinal direction" used herein refer to the front-to-back direction, while "lateral" and "lateral direction" refer to the left-to-right direction.

[0138] like Figure 9As shown, in order to secure the passage bottom shell 205 to the detachable lid assembly 13, the lid base 15 comprises a plate-like base support portion 29 which protrudes from the rear portion of the lid plate 14. The steam passage assembly 200 is straddled on the lid plate 14 and the base support portion 29. The passage bottom shell 205 can be connected to the base support portion 29 by welding, fastener connection such as screws, or any suitable means. Please refer to Figure 8 and Figure 11 The passage bottom shell 205 or the base support portion 29 is provided with a reheat steam docking lid 30 which can be closed on the top opening of the water container 41 when the lid body 3 is closed to the pot body 2. The reheat steam docking lid 30 is further provided with a reheat steam docking seal 31 for forming a seal between the water container 41 and the reheat steam docking lid 30 when the lid body 3 is closed. In other words, the reheat steam docking seal 31 is closed on the top opening as mentioned above when the lid body 3 is closed to the pot body 2. The reheat steam docking lid 30 is provided with a reheat steam inlet 201 through which reheat steam from the reheat steam generator 40 enters the reheat steam supply passage P11. The reheat steam docking lid 30 is connected to or integrally provided at the region adjacent to the rear end portion of the passage bottom shell 205 or the lid base 15, specifically at the base support portion 29. Exemplarily, the reheat steam docking lid 30 is provided at the passage bottom shell 205, and the rear end corner portion of the base support portion 29 is provided with a reheat steam docking hole 25 which is in communication with the reheat steam inlet 201 of the reheat steam supply passage P11 for guiding reheat steam from the reheat steam generator 40. The reheat steam docking seal 31 is provided through the reheat steam docking hole 25 and connected to the lid base 15.

[0139] Preferably, the passage top plate 206 is connected to the passage bottom shell 205 by a manually detachable structure, for example, the passage top plate 206 can be detachably connected to the passage bottom shell 205 by a snap structure. The snap structure is provided at the outer periphery of both the passage bottom shell 205 and the passage top plate 206. The snap structure comprises fixed snaps 212 and movable snaps 213 which correspond to different side edges of the steam passage assembly 200 respectively. The fixed snaps 212 and the movable snaps 213 can be provided at the passage bottom shell 205. The passage top plate 206 is correspondingly provided with snap positions 214 to which the fixed snaps 212 and the movable snaps 213 are detachably snapped respectively.

[0140] The region of the lid plate 14 adjacent to the rear end portion 46b is provided with an inlet and outlet concentration distribution region R of the steam passage assembly 200, Figure 8The approximate location and shape of the import and export concentrated distribution area R is shown by a dashed line. The import and export concentrated distribution area R is provided with a supplementary cooking steam outlet 202 and a cooking steam inlet 203. As shown in the example, the passage bottom shell 205 is provided with the import and export concentrated distribution area R, which is arranged in the area adjacent to the rear end portion 46b of the cover plate 14. This design ingeniously concentrates the supplementary cooking steam outlet 202 and the cooking steam inlet in a relatively small area, and it is not necessary to separately provide a sealing member and a sealing structure at the two ports, which simplifies the manufacturing and assembly process and also makes the structure more compact. The import and export concentrated distribution area R is arranged at the front end portion of the passage bottom shell 205 in the longitudinal direction.

[0141] Specifically, the passage bottom shell 205 includes a downwardly protruding steam passing portion 217, which is provided with a steam passing port 218 for communicating the steam passage P1 with the cooking cavity. The steam passing port 218 includes the supplementary cooking steam outlet 202 communicating with the supplementary cooking steam supply passage P11 and / or the cooking steam inlet 203 communicating with the cooking steam exhaust passage P12. That is, the supplementary cooking steam outlet 202 and / or the cooking steam inlet 203 are arranged in the steam passing portion 217. In the example, the import and export concentrated distribution area R is arranged in the steam passing portion 217, so that the supplementary cooking steam outlet 202 and the cooking steam inlet 203 are arranged in the steam passing portion 217. The cover plate 14 is provided with a steam passing portion passing hole 32, and the steam passing portion 217 is arranged to pass through the steam passing portion passing hole 32. The shape of the import and export concentrated distribution area R corresponds to the shape of the steam passing portion 217, for example, a circular shape, etc.

[0142] The passage bottom shell 205 can be closer to the cover plate 14 at the downwardly protruding steam passing portion 217, and the steam passing portion 217 is limited in the steam passing portion passing hole 32, which can on the one hand enable the steam passing port 218 on the steam passing portion 217 to communicate with the cooking cavity, and on the other hand limit the horizontal position of the passage bottom shell 205 at the steam passing portion 217, avoiding horizontal movement of the passage bottom shell 205 relative to the cover plate 14.

[0143] The steam passing portion 217 is located at the front end portion 211 of the passage bottom shell 205 in the longitudinal direction. In design, the steam passage assembly 200 in the longitudinal direction can be better utilized to arrange the steam passage P1 with a longer extension path, so as to miniaturize the steam passage assembly 200 in the longitudinal direction, so that the part of the steam passage assembly on the cover plate 14 has a smaller size and a smaller area ratio. The steam passing portion 217 is configured to be adapted in shape and size to the steam passing portion passing hole 32. 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 passage 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.

[0144] In some examples, the steam channel assembly is provided with a steam channel member for the steam supply channel P11. The steam channel member 208 is formed by a groove, and the side wall of the groove forms the steam supply channel P11. The steam channel member 208 is made of elastic sealing material and is in abutment with the channel top plate 206. In other words, the steam channel member 208 is a part made of flexible material. The steam channel member 208 is in sealing abutment with the channel top plate 206 to form a seal between the steam channel member 208 and the channel top plate 206. The steam channel member 208 itself has the function of sealing and elastic deformation, and can be used as a sealing member, so it can also be called a steam channel sealing member. In this way, there is no need to additionally provide a sealing ring to seal the gap between the steam channel member 208 and the channel top plate 206. In addition, the steam channel member 208 is also in sealing with the channel bottom shell 205 to avoid steam leakage.

[0145] The steam channel member 208 is provided with a pressing plate 221, which presses the bottom wall of the steam channel member 208 against the channel bottom shell 205. The side wall of the steam channel member 208 together with the pressing plate 221 forms most of the steam supply channel P11, and the top of the side wall is in abutment with 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. Near the steam outlet 202, fasteners are used to connect the pressing plate 221, the bottom wall of the channel bottom shell 205, and the cover plate 14 of the detachable cover assembly 13. The pressing plate 221 is connected to the channel bottom shell 205 by at least two fasteners. The pressing plate 221 and the steam channel member 208 are provided with locking holes 225 in spaced relation, so that the corresponding fasteners pass through.

[0146] In some alternative examples, the steam channel assembly is provided with a steam channel member that can independently form the steam supply channel. For example, the steam channel member can be formed by a tubular member such as a rubber tube, or by a separate channel.

[0147] Please refer to Figure 6 and Figure 10A steam passage cover 33 is located on the opposite side of the cover plate 14 from the steam passage assembly 200, i.e., on the lower side of the cover plate 14, to fix the steam passage part 217 to the cover plate 14. The passage bottom shell 205 (or the steam passage part 217) and the steam passage cover 33 are connected at the steam passage through hole 32, thus occupying opposite sides of the cover plate 14. The steam passage cover 33 covers the steam passage part 217 from below, and the steam passage cover 33 has a mating interface 63 corresponding to the position of the steam passage port 218 to allow steam to pass through. Preferably, the steam passage cover 33 is connected to the steam passage part 217 by fasteners, and the periphery of the steam passage cover 33 is larger than the steam passage through hole 32. The steam cover 33 is used to fix the cover plate 14 and the channel bottom shell 205 together. Compared with fasteners such as rivets, the steam cover 33 has more connecting parts and a larger connecting area with the channel bottom shell 205, so the two can be connected more firmly and reliably, thus firmly and reliably connecting the channel bottom shell 205 to the cover plate 14. Furthermore, the contact area between the steam cover 33 and the cover plate 14 is larger. During the installation process, the pressure of the steam cover 33 on the cover plate 14 is more dispersed, which can effectively prevent the cover plate 14 from undergoing local deformation, improve product quality and the overall appearance of the inner side of the cover 3.

[0148] The cover plate 14 is made of metal. Using the steam cover 33 to secure the metal cover plate effectively prevents localized deformation. The channel bottom shell 205 is made of non-metallic material. Using a non-metallic channel bottom shell 205 makes its connection structure with the steam cover 33 easier to manufacture, resulting in lower material and manufacturing costs. The steam cover 33 is also made of non-metallic material. Using a non-metallic steam cover 33 prevents scratches on the cover plate 14 during installation, and its connection structure with the channel bottom shell 205 is easy to manufacture, resulting in lower material and manufacturing costs.

[0149] like Figure 14 and Figure 15 As shown, interface 63 includes a supplementary steam interface 63a corresponding to the supplementary steam outlet 202 and a cooking steam interface 63b corresponding to the cooking steam inlet 203. The supplementary steam interface 63a is located in the center of the steam cover 33, and the cooking steam interfaces 63b are distributed around the periphery of the supplementary steam interface 63a. The supplementary steam interfaces 63a are spaced apart circumferentially along the steam cover 33; the cooking steam interfaces 63b are symmetrically distributed on both sides of the supplementary steam interface 63a. In the illustrated embodiment, there are two cooking steam interfaces 63b, symmetrically distributed on both sides of the cooking steam interface 63b. The cooking steam interfaces 63b are strip-shaped, and their extended shape corresponds to the shape of the steam cover 33; for example, if the steam cover 33 is circular, the cooking steam interface 63b is arc-shaped. This arrangement allows for smoother exhaust of cooking steam and improves exhaust efficiency.

[0150] The steam docking interface 63a of the steam replenishment includes an interface portion 36 and a flared portion 37 located at the lower side of the interface portion 36. The flared portion 37 has a larger diameter than the interface portion 36, and the diameter of the flared portion 37 gradually increases in the direction away from the interface portion 36, so that the steam injection area of the steam replenishment is enlarged, which is conducive to the steam being injected to a larger range of food. In order to improve the visual experience of the user, or in other words, to improve the visual effect of the steam cover 33, the wall surface of the flared portion 37 can be provided with a pattern 35.

[0151] As shown in Figure 14 and Figure 15 , the steam cover 33 is provided with a fixed column 61 extending upward, and correspondingly, as shown in Figure 8 , the steam cover portion 217 is provided with a fixed hole 222 suitable for the fixed column 61. The fixed column 61 is arranged in the fixed hole 222, and the fastener is locked to the fixed column 61 from the upper side of the steam cover portion. When there is a single fixed column 61, even if the fastener locks the fixed column 61, the steam cover 33 still has a certain degree of rotational freedom relative to the steam cover portion 217. Preferably, the steam cover 33 is provided with at least two fixed columns 61 extending upward and connected to the steam cover portion 217, and the at least two fixed columns 61 are arranged in a spaced manner and distributed on both sides of the center of the steam cover 33. The steam cover portion 217 is correspondingly provided with at least two fixed holes 222. For example, in the embodiment shown, the number of fixed columns 61 is two. Alternatively, the number of fixed columns 61 can also be three or more.

[0152] Further, the fixed column 61 includes a first fixed column 61a, and the fixed hole 222 includes a first fixed hole 223 corresponding to the position of the first fixed column 61a, and the first fixed column 61a is arranged in the first fixed hole 223. The fastener is locked to the first fixed column 61a located in the first fixed hole 223 from the upper side of the pressing plate 221. The fixed column 61 includes a second fixed column 61b, and the fixed hole 222 includes a second fixed hole 224 corresponding to the position of the second fixed column 61b. The steam cover portion 217 is provided with a recessed cavity 226 recessed downward from the bottom surface of the channel bottom shell 205, and the second fixed hole 224 extends downward from the bottom surface of the recessed cavity 226. The second fixed column 61b is arranged in the second fixed hole 224. The fastener is locked to the second fixed column 61b located in the second fixed hole 224 from the upper side of the recessed cavity 226.

[0153] The cover body 3 further includes a steam cover sealing member 34. The steam cover sealing member 34 is located between the steam cover 33 and the cover plate 14 and is provided with a matching hole 64. The steam port 218 is in sealed communication with the docking interface 63 via the matching hole 64. It can be understood that the matching hole 64 includes a steam replenishment matching hole 64a corresponding to the steam replenishment docking interface 63a, and a cooking steam matching hole 64b corresponding to the cooking steam docking interface 63b.

[0154] The periphery of the steam cover sealing member 34 abuts against the edge of the steam passage hole 32. The steam cover sealing member 34 can seal the gap between the steam cover 33 and the cover plate 14, so as to prevent steam from entering the cover body through the gap. Further, the steam cover 33 has a downwardly recessed accommodating portion 62, and the steam cover sealing member 34 is located in the accommodating portion 62, so that the installation position of the steam cover sealing member 34 is determined, and the sealing effect is ensured. By means of the steam cover sealing member 34, steam can be prevented from entering the cover body from between the cover plate 14 and the steam passage 217, thereby avoiding the safety hazard caused by the electrical components in the cover plate 14 being wetted, improving the sealing effect of the assembly and the safety of the product in the case of ensuring the reliability of the assembly. As known from the foregoing, the steam cover 33 is provided with a fixing column 61 connected to the steam passage 217. In the illustrated embodiment, the fixing column 61 has a first fixing column 61a and a second fixing column 61b. Correspondingly, in order to adapt to the installation of the steam cover 33, the steam cover sealing member 34 is provided with a positioning hole 65, and the fixing column 61 passes through the positioning hole 65 to position the steam cover sealing member 34.

[0155] Referring back to Figures 7 to 9 , the steam passage assembly 200 is integrally configured to have a first end section R11, a middle body section R12 and a second end section R13. Figures 7 to 9 The approximate ranges of the three sections are schematically circled by dashed lines. The middle body section R12 linearly extends from the first end section R11 to the second end section R13. The supplementary cooking steam outlet 202 is at least partially provided on the first end section R11 of the passage bottom shell 205, and the supplementary cooking steam inlet 201 is at least partially provided on the second end section R13, so that the supplementary cooking steam supply passage P11 can linearly extend on the middle body section R12. The steam passage assembly 200 has a generally linear shape in the integral configuration, and the overall external shape is relatively simple and regular, and the overall size is relatively small, so that the sealing effect is better and the sealing can be more easily provided at the outer periphery of both the passage bottom shell 205 and the passage top plate 206.

[0156] The linearly shaped steam passage assembly 200 occupies less space inside the cover body 3, so that more space inside the cover body 3 is not occupied by the steam passage assembly 200, which can be designed to mount the top heating device 100 such as an infrared heating device, effectively solving the problem of insufficient space inside the cover body 3 when the top heating device 100 and the steam passage assembly 200 are simultaneously provided. Furthermore, the material cost of the steam passage assembly 200 is reduced, the occupied space is small, the space layout of the relevant structures inside the cover body 3 can be adjusted, the overall appearance of the cover body 3 is more coordinated, and the external appearance is better.

[0157] The cooking steam inlet 203 is arranged at least partially on the first end section R11 of the passage bottom shell 205, so that the cooking steam inlet 203 can be adjacent to the complementary cooking steam outlet 202. In this way, the complementary cooking steam outlet 202 and the cooking steam inlet 203 can be designed in a relatively small area, in other words, the first end section R11 has an inlet and outlet concentrated distribution area R. The cooking steam outlet 204 is arranged at least partially on the first end section R11 of the passage top plate 206, so that the cooking steam outlet 204 can be located in an area corresponding to the position of the cooking steam inlet 203. The cooking steam exhaust passage P2 on the cover body is located in the position corresponding to the first end section R11, so that the cooking steam outlet 204 located in the first end section R11 is in communication with the cooking steam exhaust passage P2. The position of the cooking steam exhaust passage P2 is moved forward from the rear end of the cover body 3 by a certain distance, so that the rear part of the cover body 3 can be reduced in size, which is beneficial to the miniaturization of the cover body 3.

[0158] The temperature measuring hole 219 is located in the second end section R13 of the passage top plate 206, so that the complementary cooking steam temperature measuring element 53 can be at least partially located in an area corresponding to the position of the complementary cooking steam inlet 201 via the temperature measuring hole 219 located in the second end section R13. The complementary cooking steam temperature measuring device 52 can detect the steam just entering the complementary cooking steam supply passage P11, ensuring that the temperature of the complementary cooking steam meets the cooking requirements.

[0159] The first end section R11 is arranged at the rear end of the cover plate 14 and on the longitudinal center line of the detachable cover assembly 13, and the second end section R13 is arranged at the rear corner of the cover plate seat 15. The area near the rear end of the detachable cover assembly 13 can be used to layout the steam passage assembly 200. The steam passage assembly 200 occupies a relatively small cooking area of the detachable cover assembly 13 corresponding to the cooking cavity, and the cooking area of the detachable cover assembly 13 not occupied by the steam passage assembly 200 is relatively large, so this area can be designed in a variety of ways. The first end section R11 is on the longitudinal center line of the detachable cover assembly 13. The complementary cooking steam outlet 202 can spray complementary cooking steam from the transverse center of the detachable cover assembly 13, and the spraying area in the transverse direction can be approximately the same, and the complementary cooking effect is better.

[0160] Optionally, as shown in Figure 10 The rear corner of the cover plate seat 15 is provided with a protruding portion 66 protruding from the rear edge of the cover plate seat 15. The second end section R13 can be arranged on the protruding portion 66. The rear end of the steam passage assembly 200 is supported on the protruding portion 66. The outer contour of the protruding portion 66 corresponds to the shape and size of the outer contour of the second end section R13 of the steam passage assembly 200. The area of the rear part of the cover plate seat 15 not occupied by the steam passage assembly 200 is small in size, which reduces the material cost of the cover plate seat 15 and is beneficial to the miniaturization of the product.

[0161] Optionally, the outer contour of the first end section R11 and the second end section R13 is configured in an arc shape, and the side contour of the middle body section R12 is configured in a straight line shape. The size of the steam channel assembly 200 at both ends can be designed smaller, further reducing its occupation space inside the cover body 3, improving space utilization; and the overall appearance of the steam channel assembly 200 is more coordinated, and the external appearance is better.
