Specifically, the detachable cover assembly 13 is arranged at the lower side or inner side of the inner liner 9 and is detachably connected to the inner liner 9. For example, the detachable cover assembly 13 is movably connected to the inner liner 9 through a plug-in and / or clamping structure. The detachable cover assembly 13 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 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.

[0117] 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 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.

[0118] 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 is connected to the base 18, so it is also called a bottom heating device.

[0119] 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 generate heat that can be transmitted 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.

[0120] 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 the cooking steam for the cooking cavity, specifically, it can receive the cooking steam from the steam generating device 40 and deliver the cooking steam to the cooking cavity.

[0121] The steam generating device 40 can be arranged in the cover body 3 or the pot body 2. Figure 2 An example of the steam generating device 40 arranged in the pot body 2 is shown schematically. 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 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 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 to heat the water in the water container to generate 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 above-mentioned example.

[0122] When the cooking appliance 1 is in use, heating food and water in the inner pot 4 will generate cooking steam. In order to discharge the cooking steam to the outside environment, the cover body 3 is provided with a cooking steam discharge passage P12 and a steam discharge passage P2, as shown in Figure 3 and Figure 4 The cover body 3 is further provided with a cooking steam discharge passage P12 and a steam discharge passage P2 for the steam discharged from the cooking cavity to pass through. The cooking steam discharge passage P12 is in communication with the cooking cavity and the steam discharge passage P2 is in communication with the cooking steam discharge passage P12. The cooking steam can first enter the cooking steam discharge passage P12 and then be discharged to the outside environment through the steam discharge passage P2.

[0123] For the infrared heating device, one example is that the infrared heating device comprises an infrared heating tube and a light-transmissive isolation plate. For example, the infrared heating tube is formed by encapsulating an infrared heating element in a glass tube, and the isolation plate is arranged at the lower side of the infrared heating tube. Another alternative example is that the infrared heating tube can be replaced by an electric heating film arranged on a plate-shaped member and capable of being electrified, and in this example, the plate-shaped member for arranging the electric heating film is at least partially light-transmissive. The infrared heating device further comprises a reflecting member 111 for reflecting the upwardly radiated infrared rays to the cooking cavity, so as to improve the heating efficiency.

[0124] Another alternative example is that the infrared heating device comprises a radiation plate and a heating assembly 120 for heating the radiation plate, and the heating assembly 120 is located at the upper side of the radiation plate. The heat generated by the heating assembly 120 can be transferred to the radiation plate, and the radiation plate can radiate infrared rays to the cooking cavity after being heated. The radiation plate can be a ceramic plate, a carbon plate made of carbon material, etc. The radiation plate is exposed in the cooking cavity, and at least part of the lower surface of the radiation plate forms the top surface of the cooking cavity. The temperature of the radiation plate can be controlled by controlling the power or heating temperature of the heating assembly 120.

[0125] The structure of the cover body 3 is further described by taking an example. As shown in Figure 4 The inner liner 9 is provided with an inner liner through hole 20, and the isolation plate 110 is installed at the inner liner through hole 20. The cover plate 14 is arranged below the isolation 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 isolation plate 110. In other words, the cover plate through hole 21 is directly below the isolation plate 110. The infrared rays generated by the isolation 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 is at least partially light-transmissive. The cover plate 14 can be entirely made of a light-transmissive material such as glass, or the portion corresponding to the isolation plate 110 is made of a light-transmissive material.

[0126] 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.

[0127] 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 interior 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.

[0128] In order to simplify the structure and optimize the utilization 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 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.

[0129] Please refer to Figure 8The steam passage assembly 200 is further provided with a supplementary cooking steam inlet 201 and a supplementary cooking steam outlet 202 which are in communication with the supplementary cooking steam supply passage P11. The supplementary cooking steam inlet 201 is configured to receive steam from the steam generation device 40, and the supplementary cooking steam outlet 202 is configured to communicate the supplementary cooking steam supply passage P11 with the cooking cavity. The supplementary cooking 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 from water in the water container 41 after being heated enters the supplementary cooking steam supply passage P11 via the supplementary cooking steam inlet 201, flows along the supplementary cooking steam supply passage P11, and enters the cooking cavity via the supplementary cooking steam outlet 202.

[0130] Referring to Figure 8 and Figure 13 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 exhaust passage P12. The cooking steam inlet 203 is configured to communicate the cooking steam exhaust passage P12 with the cooking cavity, and the cooking steam outlet 204 is configured to exhaust steam in the cooking steam exhaust passage P12. The lid body 8 is provided with the steam exhaust passage P2. The cooking 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 3 further comprises a steam passage structure forming the steam exhaust passage P2, which can include a steam valve 27 and a steam seal 28 which are vertically disposed 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 cooking steam exhaust passage P12 via the cooking steam inlet 203, flows along the cooking steam exhaust passage P12, and flows to the steam exhaust passage P2 via the cooking steam outlet 204, and is then exhausted to the ambient environment.

[0131] 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 long strip shape.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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 lid 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 lid assembly 13 can be detached from the lid 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 lid assembly 13 and the channel bottom shell 205 detached from the lid body 3 can be cleaned by the user with water, and the channel top plate 206 detached from the lid body 3 can be cleaned by the user with water separately. The user can easily clean the steam channel P1 with good cleaning effect.

[0136] Alternatively, the channel top plate 206 is connected to the lid body 8. The channel top plate 206 is closed on 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 lid assembly 13 can be detached from the lid 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 lid assembly 13 and the channel bottom shell 205 detached from the lid body 3 can be cleaned by the user with water, and the channel top plate 206 retained on the lid 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 lid assembly 13 when the detachable lid assembly 13 is mounted to the lid body 3 to form the enclosed steam channel P1.

[0137] The channel bottom shell 205 is provided with the above-mentioned make-up steam outlet 202 and the cooking steam inlet 203. The channel top plate 206 is provided with the cooking steam outlet 204. In other examples not shown, the lid plate 14 can be provided with the above-mentioned make-up steam outlet 202 and the cooking steam inlet 203, and the channel bottom shell 205 is provided with a channel structure at positions corresponding to the make-up steam inlet 201 and the make-up steam outlet 202. The channel structure is sandwiched between the lid plate 14 and a sealing member. In the illustrated example where the steam generation device 40 is arranged in the pot body 2, the channel bottom shell 205 is provided with the above-mentioned make-up steam inlet 201 to admit steam from the lower side. In the example where the steam generation device 40 is arranged in the lid body 3, the channel top plate 206 is provided with the above-mentioned make-up steam inlet 201 to admit steam from the upper side.

[0138] 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.

[0139] The construction of the steam channel assembly 200 is further described below using the illustrated example.

[0140] 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.

[0141] 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.

[0142] 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.

[0143] 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.

[0144] 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.

[0145] 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.

[0146] 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.

[0147] 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.

[0148] In some examples, the steam channel assembly 200 is made of a flexible material. In some examples, the steam channel assembly 200 is made of a flexible sealing material and abuts against the channel top plate 206. In other words, the steam channel assembly 200 is a part made of a flexible material. The steam channel assembly 200 is thus sealed against the channel top plate 206 to form a seal between the steam channel assembly 200 and the channel top plate 206. The steam channel assembly 200 itself has a sealing function and the ability to elastically deform, and can be used as a seal, and can thus be referred to as a steam channel seal. In this way, a separate sealing ring is not required to seal the gap between the steam channel assembly 200 and the channel top plate 206. In addition, a seal is also formed between the steam channel assembly 200 and the channel bottom shell 205, preventing steam from leaking out.

[0149] The steam channel assembly 200 is provided with a pressing plate 221, which presses the bottom wall of the steam channel assembly 200 against the channel bottom shell 205. The side wall of the steam channel assembly 200, together with the pressing plate 221, forms most of the steam supply channel P11.
