It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0104] like Figures 1 to 5 As shown, this application provides a cooking appliance 1, which includes a pot body 2 and a lid 3. The pot body 2 has a cylindrical inner pot storage section. The inner pot 4 can be fixedly installed in the inner pot storage section, or can be freely placed into or removed from the inner pot storage section for easy cleaning. The inner pot 4 is usually made of metal and has a circular opening on its upper surface for holding materials to be heated, such as rice or soup. The pot body 2 includes an inner pot heating device 5, such as a heating plate, for heating the inner pot 4.

[0105] It is understood that the cooking appliance 1 according to this application can be a rice cooker, an electric pressure cooker or other cooking appliance 1, and the cooking appliance 1 can have various functions such as cooking porridge in addition to cooking rice.

[0106] The cover 3 has a shape substantially corresponding to that of the pot body 2. The cover 3 is arranged on the pot body 2 in a manner that can be opened and closed. In one example, the cover 3 is pivotally connected to the pot body 2 by a pivot shaft 6, and can be freely pivoted about a pivot axis defined by 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 3 is connected to the pot body 2 by fasteners that are cooperatively engaged and easily detachable, so that the two are tightly connected together during cooking, and are detached into two independent whole bodies during cleaning, for example. When the cover 3 is closed on the pot body 2, it covers the inner pot 4, and together with the inner pot 4 defines a cooking cavity. The cover 3 also usually has a pot opening sealing ring 7 made of rubber material, for example, arranged between the cover 3 and the inner pot 4, to seal the cooking cavity when the cover 3 is in the closed state.

[0107] It should be noted that the directional terms used herein in describing various components, parts, etc. of the cooking appliance 1, such as "upper", "lower", "upper side", "lower side", "upward", "downward", "upwardly", "downwardly", etc. are relative to the cooking appliance 1 in a horizontal placement, upright state and with the cover 3 in the closed state.

[0108] The cover 3 substantially comprises a cover main body 8. The cover main body 8 comprises 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.

[0109] In one example, the cover 3 further comprises a detachable cover assembly 13. The detachable cover assembly 13 is arranged on the lower side of the cover main body 8 and is detachably connected to the cover main body 8 in the form of an assembly, so that the detachable cover assembly 13 is detachably mounted on the cover 3 from the lower side. When the detachable cover assembly 13 needs to be cleaned, it can be detached from the cover 3. Specifically, the detachable cover assembly 13 is arranged on 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 by a plug-in and / or clamping structure. The detachable cover assembly 13 substantially comprises a cover plate 14, a cover plate seat 15 and the aforementioned pot opening sealing ring 7. The cover plate 14 can be optionally a metal plate. At least part of the lower surface of the cover plate 14 forms a 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 fastener tightening, etc. Part of the pot opening sealing ring 7 is pressed between the cover plate 14 and the cover plate seat 15.

[0110] In another alternative example, the cover body 3 comprises the cover plate 14 described above, which is fixedly connected to the cover main body 8, in particular to the inner liner 9, so that the cover plate 14 is non-detachably mounted on the cover body 3.

[0111] The pot body 2 basically comprises an outer shell 16, a middle plate 17 located on the upper side of the outer shell 16, and a base 18 located on 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 of fasteners such as screws, bonding, or any suitable method. The lower end of the outer shell 16 can be connected to the upper end of the base 18 by clamping, fastening by means of fasteners such as screws, bonding, or any suitable method. The outer shell 16, the middle plate 17, and the base 18 together form an inner pot receiving portion. The inner pot heating device 5 can be arranged between the base 18 and the bottom of the inner pot 4 and connected to the base 18, so it is also called a bottom heating device. Alternatively, another inner pot heating device 5 can be arranged between the outer shell 16 and the side of the inner pot 4, so it is also called a side heating device.

[0112] 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 generates heat that can be transmitted to the cooking cavity by means 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, 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 around the coil disc. In this scheme, the cover plate 14 on the lower side of the coil disc is a metal component. The alternating magnetic field generated by the electromagnetic coil can act on the metal cover plate 14 below, causing the cover plate 14 to heat 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 layer of food and make the food evenly heated, thereby stimulating the aroma of the food.

[0113] The cooking appliance 1 of the present application also has the function of steam heating. 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 can be delivered to the cooking cavity during the holding stage to keep the food such as rice moist and prevent the food from drying out and turning yellow. Specifically, the cooking appliance 1 further comprises a steam generating device 40 for generating steam. In order to deliver the steam to the cooking cavity, the cover body 3 is provided with a steam inlet passage P11 communicating with the cooking cavity. The steam inlet passage P11 can receive steam from the steam generating device 40 and deliver steam to the cooking cavity.

[0114] The steam generating device 40 can be located on the lid 3 or the pot body 2. Figure 4 An example of a steam generator 40 disposed in the pot body 2 is shown schematically. Figure 4 As shown, the steam generating device 40 basically includes a water container 41 and a water container heating device 42. The water container 41 is disposed in the pot body 2 and is capable of storing water for generating steam. Optionally, the water container 41 is located within the receiving cavity of the pot body 2, and its top protrudes from the upper surface of the pot body 2 to facilitate removal of the water container 41 from the pot body 2. The water container 41 has a top opening for forming an outlet to allow steam to escape. The water container heating device 42 is typically disposed below the water container 41 and is used to heat the water in the water container 41 to generate steam. This steam can enter the steam inlet passage P11 and then into the cooking cavity to keep food such as rice in the inner pot 4 moist. When the steam generating device 40 is disposed in the lid 3, the placement and structure of the water container 41 and the water container heating device 42 are the same as... Figure 4 The examples shown are different.

[0115] When cooking, the food and water in the inner pot 4 of the cooking appliance 1 generate steam. To vent the steam generated during cooking to the outside environment, such as... Figure 5 As shown, the cover 3 is also provided with a steam outlet channel P12 and a steam exhaust channel P2 that are connected to the cooking chamber. The steam in the cooking chamber can first enter the steam outlet channel P12 and then be discharged to the outside environment through the steam exhaust channel P2.

[0116] For an infrared heating device, one example is that the infrared heating device can be an infrared heating tube. For example, an infrared heating element is encapsulated in a glass tube to form an infrared heating tube. In this example, the cover 3 also includes a light-transmitting isolation plate disposed below the infrared heating tube. An alternative example is that the infrared heating device can be an electrically conductive heating film arranged on a plate-like component. In this example, the plate-like component used to arrange the heating film is at least partially light-transmitting. Another alternative example, referring to the illustrated example, is that the infrared heating device includes a radiant plate 110 and a heating assembly 120 for heating the radiant plate 110. The heat generated by the heating assembly 120 can be transferred to the radiant plate 110, and the heated radiant plate 110 can radiate infrared rays into the cooking cavity. The radiant plate 110 can be a ceramic plate, a carbon plate made of carbon material, etc. A light-transmitting isolation plate can be disposed below the radiant plate 110. Alternatively, the radiant plate 110 is exposed inside the cooking cavity, with at least a portion of its lower surface forming the top surface of the cooking cavity; more specifically, at least a portion of the radiant plate 110 forms the top wall of the cooking cavity. The temperature of the radiant plate 110 can be controlled by controlling the power or heating temperature of the heating assembly 120.

[0117] Using the illustrated example, the structure of cover 3 will be further described. For example... Figure 3 and Figure 7As shown, the inner liner 9 is provided with an inner liner opening 20, and the radiation plate 110 is installed at the inner liner opening 20. The cover plate 14 is arranged below the radiation plate 110. The cover plate 14 is partially provided with a cover plate opening 21. The cover plate opening 21 corresponds to the position of the radiation plate 110. In other words, the cover plate opening 21 is directly below the radiation plate 110. The infrared rays generated by the radiation plate 110 can be radiated toward the inner pot 4 via the inner liner opening 20 and the cover plate opening 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 radiation plate 110 is made of a light-transmissive material. At this time, the cover plate 14 serves as an isolation plate.

[0118] As shown in FIG. 1, the top heating device 100 can further include a radiation plate 110. The radiation plate 110 is arranged on the inner liner 9. The radiation plate 110 can be arranged on the inner liner 9 in a manner that the radiation plate 110 is directly below the cover plate 14. The radiation plate 110 can be arranged on the inner liner 9 in a manner that the radiation plate 110 is directly below the cover plate opening 21. The radiation plate 110 can be arranged on the inner liner 9 in a manner that the radiation plate 110 is directly below the inner liner opening 20. Figure 6 and Figure 7 As shown, the inner liner 9 can be provided with a support portion 22. The support portion 22 is arranged around the inner liner opening 20, and the support portion 22 forms a closed annular structure. The outer edge of the radiation plate 110 can be lapped on the bottom wall of the support portion 22 and abut against the side wall of the support portion 22. The support portion 22 can provide upward support to the radiation plate 110 and limit the movement of the radiation plate 110 in the horizontal direction, facilitating the fixation of the radiation plate 110. One example is that the support portion 22 can be concave downward, and the radiation plate 110 is accommodated in the concave support portion 22. Another example is that the support portion 22 is a planar structure, i.e., does not form a concave portion. The outer peripheral portion of the radiation plate 110 is sleeved with a peripheral sealing ring 130 to form a seal between the radiation plate 110 and the inner liner 9. The top heating device 100 further includes a fixing member 140. The fixing member 140 can be connected with the inner liner 9, and the outer edge of the radiation plate 110 is clamped between the fixing member 140 and the support portion 22. The fixing member 140 is optionally arranged in an annular shape, which can be connected with the inner liner 9 by clamping, fastening by fasteners such as screws, welding, or other suitable methods.

[0119] In addition, the cover body 3 can further include an opening sealing ring 23. The opening sealing ring 23 can be arranged at the edge of the cover plate opening 21 and between the radiation plate 110 and the inner liner 9, and abut against the lower surface of the radiation plate 110. The formation of the seal at the cover plate opening 21 can prevent steam from entering the interior of the cover body 3 through the gap between the radiation plate 110 and the cover plate 14, thereby improving the sealing effect of the cover body 3. For example, a press ring 24 can be arranged to clamp a portion of the opening sealing ring 23 between the press ring 24 and the cover plate 14, and the press ring 24 can be fixed with the cover plate 14 by bendable clamping corners.

[0120] The shape of the inner liner opening 20, the shape of the cover plate opening 21, the shape of the support portion 22, the shape of the opening sealing ring 23, and the shape of the radiation plate 110 correspond to each other. For example, the radiation plate 110 can be provided with a relief notch 111, and the inner liner 9 is provided with a protruding portion 25 protruding towards the center of the inner liner opening 20, and the protruding portion 25 is engaged with the relief notch 111. Optionally, 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 to each other in position. A part of the steam channel P1 can be arranged on the protruding portion 25. In this way, the area of the radiation plate 110 can be designed to be larger, and the steam channel P1 can also be arranged on one side of the radiation plate 110, specifically the back side, with a suitable area ratio. The steam channel P1 here includes the steam inlet channel P11 and / or the steam outlet channel P12 described above.

[0121] In order to simplify the structure and optimize the use of the space in the cover body 3, the steam inlet channel P11 and the steam outlet channel P12 are formed by one component in the present application, rather than by different components. Specifically, the cover body 3 further includes a steam channel assembly 200 for forming the steam inlet channel P11 and the steam outlet channel P12. The steam channel assembly 200 is located on the upper side of the cover plate 14 and the lower side of the inner liner 9. The steam channel assembly 200 is located on one side of the top heating device 100, specifically the back side of the top heating device 100. As shown in Figure 8 The inner liner 9 has a recess 26 for accommodating the steam channel assembly 200. The recess 26 is located on the back side of the inner liner opening 20 and is recessed upward from the lower surface of the inner liner 9. At least part of the steam channel 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 channel assembly 200.

[0122] As shown in Figure 9 , Figure 10 and Figure 11 The steam channel assembly 200 is also provided with a steam supply port 201 and a steam inlet port 202 which communicate with the steam inlet channel P11. The steam supply port 201 is used to receive steam from the steam generating device 40, and the steam inlet port 202 is used to communicate the steam inlet channel P11 with the cooking cavity. The position of the steam supply port 201 corresponds to the outlet of the water container 41, specifically above the water container 41. Figure 4 The steam inlet flow path is schematically indicated by arrows. Specifically, the steam generated by heating the water in the water container 41 enters the steam inlet channel P11 through the steam supply port 201, flows along the steam inlet channel P11, and enters the cooking cavity through the steam inlet port 202.

[0123] The steam passage assembly 200 is further provided with a steam outlet 203 and a steam exhaust outlet 204 which are in communication with the steam outlet passage P12. The steam outlet 203 is configured to communicate the steam outlet passage P12 with the cooking cavity, and the steam exhaust outlet 204 is configured to exhaust steam in the steam outlet passage P12. The lid body 8 is provided with the steam exhaust passage P2 as described above. The steam exhaust outlet 204 is positioned corresponding to the steam exhaust 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 exhaust passage P2 and are vertically arranged in the lid body 8. The steam seal 28 is arranged at the bottom of the steam valve 27 and abuts against the upper surface of the steam passage assembly 200. Figure 5 The steam outlet flow path is schematically indicated by arrows, i.e. steam in the cooking cavity enters the steam outlet passage P12 via the steam outlet 203, flows along the steam outlet passage P12, and flows to the steam exhaust passage P2 via the steam exhaust outlet 204, and then is exhausted to the ambient environment.

[0124] The steam passage assembly 200 comprises a passage bottom plate 205 and a passage top plate 206. The passage top plate 206 is arranged on the upper side of the passage bottom plate 205 and is coverable to the passage bottom plate 205. The steam seal 28 abuts against the upper surface of the passage top plate 206. The outer periphery of the passage bottom plate 205 and the passage top plate 206 correspond in shape and size. The outer periphery of the passage bottom plate 205 and the passage top plate 206 is schematically shown as a substantially triangular shape.

[0125] The passage bottom plate 205 and the passage top plate 206 form the steam inlet passage P11 and the steam outlet passage P12 therebetween. Further, the two steam passages P1 are partly formed by the passage bottom plate 205 or components thereon, and partly formed by the passage top plate 206 or components thereon. The steam passage assembly 200 comprises two passage seals 207 which are configured to form seals at the steam inlet passage P11 and the steam outlet passage P12, respectively. In one example, the steam inlet passage P11 and the steam outlet passage P12 are arranged at different regions of the passage bottom plate 205. In this example, the passage bottom plate 205 forms the bottom walls of the two steam passages P1, so that the passage bottom plate 205 and the passage top plate 206 enclose the two steam passages P1. Alternatively, the passage bottom plate 205 is provided with bottom wall members which are configured to form the bottom walls of the two steam passages P1; in this arrangement, the bottom wall members can be configured to secure the passage seals 207 (described in detail below) which abut against the passage top plate 206. Thus, the bottom wall members, the passage seals 207 and the passage top plate 206 enclose the two steam passages P1.

[0126] In another example, as shown in FIG. 6, the steam passage assembly 200 is arranged in the lid body 8. The steam passage assembly 200 comprises a passage bottom plate 205 and a passage top plate 206. The passage top plate 206 is arranged on the upper side of the passage bottom plate 205 and is coverable to the passage bottom plate 205. The steam seal 28 abuts against the upper surface of the passage top plate 206. The outer periphery of the passage bottom plate 205 and the passage top plate 206 correspond in shape and size. The outer periphery of the passage bottom plate 205 and the passage top plate 206 is schematically shown as a substantially triangular shape. Figure 9As shown, the steam inlet passage P11 is provided inside the steam outlet passage P12. In this example, the passage bottom plate 205 or a bottom wall member thereon forms a bottom wall of the steam outlet passage P12, such that the passage bottom plate 205 or the bottom wall member thereon and the passage top plate 206 enclose the steam outlet passage P12. The steam passage assembly 200 further comprises a steam inlet passage member 208 provided between the passage bottom plate 205 and the passage top plate 206. The steam inlet passage member 208 on the passage bottom plate 205 forms at least a bottom wall of the steam inlet passage P11, such that the steam inlet passage member 208 and the passage top plate 206 enclose the steam inlet passage P11.

[0127] In the example where the passage bottom plate 205 forms a bottom wall of the steam passage P1, the passage bottom plate 205 is provided with a passage wall 209 extending upwardly from an upper surface of the passage bottom plate 205, which encloses a peripheral side wall of the steam passage P1.

[0128] The cover plate 14 needs to be made of food grade material as it forms a top wall of the cooking cavity. The passage bottom plate 205 and the passage top plate 206 are separate 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 plate 205, the passage top plate 206, the bottom wall member and / or the steam inlet passage member 208 are also made of food grade material. With this design, the top wall of the steam passage P1 can be formed without the cover body 8, so that the cover body 8 does not need to be made of food grade material, thereby saving material cost.

[0129] The steam passage assembly 200 is at least partially mounted on the removable lid assembly 13, such that the steam passage assembly 200 is at least partially removed from the lid body 3 together with the removable lid assembly 13 for cleaning the two steam passages P1. For the example shown, at least the passage bottom plate 205 is mounted on the removable lid assembly 13, such that at least the passage bottom plate 205 is removed from the lid body 3 together with the removable lid assembly 13. In particular, the passage bottom plate 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. As a result, at least the passage bottom plate 205 can be removed from the lid body 3 for cleaning the two steam passages P1. The passage top plate 206 can be separated from the passage bottom plate 205 to expose the interior of the steam passage P1 for better cleaning of the interior of the steam passage P1.

[0130] In the illustrated example, the channel top plate 206 is detachably connected with the channel bottom plate 205 so as to be detached from or mounted to the cover body 3 together with the channel bottom plate 205. When the steam channel P1 needs to be cleaned, 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 plate 205. In this way, part of the steam channel P1 on the channel top plate 206 is exposed, and part of the steam channel P1 on the channel bottom plate 205 is also exposed. The detachable cover assembly 13 and the channel bottom plate 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. The user can easily clean the steam channel P1, and the cleaning effect is good.

[0131] Alternatively, the channel top plate 206 is connected with the cover body 8. The channel top plate 206 covers the channel bottom plate 205, and the two can be connected without being fixed. When the steam channel P1 needs to be cleaned, the whole of the channel bottom plate 205 and the detachable cover assembly 13 can be detached from the cover body 3. In this way, part of the steam channel P1 on the channel top plate 206 is exposed, and part of the steam channel P1 on the channel bottom plate 205 is also exposed. The detachable cover assembly 13 and the channel bottom plate 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 water. In this scheme, the channel top plate 206 is butted against the channel bottom plate 205 on the detachable cover assembly 13 when the detachable cover assembly 13 is mounted to the cover body 3, so as to form a closed steam channel P1.

[0132] The channel bottom plate 205 is provided with the steam inlet 202 and the steam outlet 203. The channel top plate 206 is provided with the steam outlet 204. In other examples not shown, the cover plate 14 can be provided with the steam inlet 202 and the steam outlet 203, and the channel bottom plate 205 is provided with a channel structure at positions corresponding to the steam supply port 201 and the steam inlet 202. The channel structure is clamped with a sealing element between the channel structure and the cover plate 14. In the illustrated example in which the steam generation device 40 is arranged in the pot body 2, the channel bottom plate 205 is provided with the steam supply port 201 to allow steam to enter from the lower side. In the example in which the steam generation device 40 is arranged in the cover body 3, the channel top plate 206 is provided with the steam supply port 201 to allow steam to enter from the upper side.

[0133] Referring back to Figure 6 and Figure 8 , the cover body 3 further comprises a temperature measuring device 50 for detecting the temperature of the steam in the cooking cavity. The temperature measuring device 50 comprises a temperature measuring element 51. The channel top plate is provided with a temperature measuring hole 219, and at least part of the temperature measuring element 51 is arranged in the steam outlet channel P12 via the temperature measuring hole 219.

[0134] The structure of the steam channel assembly 200 will be further described below with reference to the illustrated example.

[0135] As shown in Figure 12 and Figure 13 The channel base 205 extends beyond the rear of the cover plate 14 in both the longitudinal direction and the lateral direction of the horizontal plane, with the steam supply port 201 located at the lateral end 210 of the channel base 205 in the lateral direction. The steam generator 40 is arranged at the corner of the kettle body 2 at the rear end, and the lateral end 210 of the channel base 205 in the lateral direction corresponds to the corner of the cover body 3. In this way, the position of the steam supply port 201 can be corresponded to the water container 41 of the steam generator 40 vertically, and steam enters the steam supply port 201 from the bottom to the top, so that the steam path between the steam supply port 201 and the water container 41 is short and straight. At least the steam inlet port 202 is located at the front end 211 of the channel base 205 in the longitudinal direction. For the example shown, both the steam inlet port 202 and the steam outlet port 203 are arranged at the front end 211 of the channel base 205 in the longitudinal direction. The steam exhaust port 204 is spaced apart from the steam outlet port 203 in the longitudinal direction and is on the longitudinal center line of the cover plate 14.

[0136] The steam inlet channel P11 extends between the steam supply port 201 and the steam inlet port 202, in other words, the steam supply port 201 and the steam inlet port 202 are respectively located at the two ends of the steam inlet channel P11. Alternatively, the steam inlet channel P11 is a straight channel, the center line of which has a predetermined angle with the center line of the cover plate 14 extending in the front-rear direction. Further, the steam inlet channel P11 is inclined with respect 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 both the cover plate 14 and the detachable cover assembly 13 are collinear.

[0137] It should be noted that the term "longitudinal" or "longitudinal direction" used herein refers to the front-rear direction, and the term "lateral" or "lateral direction" refers to the left-right direction.

[0138] As shown in Figure 14 In order to fix the channel base 205 to the detachable cover assembly 13, the cover plate seat 15 includes a seat support portion 29 in the form of a plate, which protrudes from the rear of the cover plate 14. The channel base 205 can be connected to the seat support portion 29 by channel welding, fasteners such as screws, or other suitable means. The seat support portion 29 is also provided with a water container cover 30, which can cover the top opening of the water container 41 when the cover body 3 is closed to the kettle body 2. The water container cover 30 is also provided with an outlet sealing member 31, which forms a seal between the water container 41 and the water container cover 30 when the cover body 3 is closed.

[0139] The channel top plate 206 can be detachably connected to the channel bottom plate 205 through a buckle structure. The buckle structure includes a fixed buckle 212 and a movable buckle 213, which correspond to different side edges of the steam channel assembly 200 respectively. The fixed buckle 212 is connected to the channel bottom plate 205 and is provided with a buckle opening 214. The movable buckle 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 buckle 212 and a second protruding buckle 216 matched with the movable buckle 213. The first protruding buckle 215 can be buckled into the buckle opening 214 of the fixed buckle 212, and the second protruding buckle 216 can be buckled from the upper side by the movable buckle 213. The seat support part 29 is spaced apart and provided with an upwardly protruding column, and the movable buckle 213 is rotatably connected to the column. When assembled, the first protruding buckle 215 is buckled into the buckle opening 214 of the fixed buckle 212 first, to realize the fixation of one side edge of the assembly; and then the movable buckle 213 is rotated to be buckled in the second protruding buckle 216, to realize the fixation of the other side edge of the assembly. When disassembled, the movable buckle 213 is unlocked first, and then the fixed buckle 212 is separated.

[0140] The channel bottom plate 205 includes a downwardly protruding steam exchange part 217, which is provided with a steam exchange opening 218 for communicating the steam channel P1 with the cooking cavity. The steam exchange opening 218 includes a steam inlet opening 202 communicated with the steam inlet channel P11 and / or a steam outlet opening 203 communicated with the steam outlet channel P12. That is, the steam inlet opening 202 and / or the steam outlet opening 203 are arranged on the steam exchange part 217. The illustrated example is that the steam inlet opening 202 and the steam outlet opening 203 are arranged on the steam exchange part 217. The cover plate 14 is provided with a cover plate opening 32, and the steam exchange part 217 is arranged in the cover plate opening 32. The channel bottom plate 205 can be closer to the cover plate 14 at the downwardly protruding steam exchange part 217, and the steam exchange part 217 is limited in the cover plate opening 21, which can on the one hand enable the steam exchange opening 218 on the steam exchange part 217 to communicate with the cooking cavity, and on the other hand limit the horizontal position of the channel bottom plate 205 at the steam exchange part 217, to avoid the horizontal movement of the channel bottom plate 205 relative to the cover plate 14.

[0141] The steam exchange part 217 is located at the front end part 211 of the channel bottom plate 205 in the longitudinal direction. In design, the steam channel assembly 200 in the longitudinal direction can be better utilized to arrange the steam channel P1 with a longer extension path, so as to miniaturize the steam channel assembly 200 in the longitudinal direction, so that the part of the steam channel assembly on the cover plate 14 has a smaller size and a smaller area ratio. The steam exchange part 217 is configured to be adapted in shape and size to the cover plate opening 32. The structure between the steam exchange part 217 and the cover plate 14 can be more compact, which is beneficial to effectively limiting the horizontal movement of the channel bottom plate 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.

[0142] The cover body 3 further comprises a fixing member 33 and a cover plate seal 34. The fixing member 33 is located at the lower side of the cover plate 14 to fix the steam exchange portion 217 to the cover plate 14. The cover plate seal 34 is arranged between the cover plate 14 and the steam exchange portion 217 to form a seal between the cover plate 14 and the steam exchange portion 217. The steam exchange portion 217 is located in the cover plate opening 32 and connected to the fixing member 33, the edge of the cover plate opening 32 can be clamped between the steam exchange portion 217 and the fixing member 33, and the cover plate seal 34 is clamped between the cover plate 14 and the steam exchange portion 217. Alternatively, the fixing member 33 is welded to the steam exchange portion 217. Alternatively, the fixing member 33 is connected to the steam exchange portion 217 by threads.

[0143] One of the prominent optimization improvements of the present application is that the channel member 220 used to form the steam passage P1 is made of elastic sealing material to serve as a seal.

[0144] As shown in Figures 15 to 21 The steam passage assembly 200 comprises a channel member 220. The channel member 220 is arranged between the channel bottom plate 205 and the channel top plate 206, and the channel member 220 and the channel top plate 206 enclose the steam passage P1. The channel member 220 is configured to have a bottom wall of the steam passage P1, and the channel top plate 206 serves as a top wall of the steam passage P1. The channel member 220 is integrally made of elastic sealing material, so that the channel member 220 and the channel top plate 206 are sealingly abutted to form a seal therebetween. The channel member 220 itself has a sealing function and an elastic deformation capability, and can serve as a seal, so it can also be referred to as a channel seal 207. In this way, there is no need to additionally provide a sealing ring to seal the gap between the channel member 220 and the channel top plate 206, and there is no need to provide a pressing plate to fix the sealing ring, thereby reducing the number of components, simplifying the structure and assembly process, and facilitating the effective use of the internal space of the cover body 3 and the improvement of the assembly efficiency. In addition, a seal is also formed between the channel member 220 and the channel bottom plate 205 to prevent steam leakage.

[0145] As described above, the channel top plate 206 can be separated from the channel bottom plate 205 to expose the inside of the steam passage P1; at least the channel bottom plate 205 is detached from or mounted to the cover body 3 to clean the steam passage P1. Further, the channel member 220 is detachably connected to the channel bottom plate 205 so as to be separately detached after being detached together with the channel bottom plate 205 from the cover body 3. The channel member 220 is separately detached, so that the channel member 220 can be cleaned, whether it is the inner surface or the outer surface or other positions of the channel member 220, so that the channel member 220 can be kept clean and bacteria-free, thereby improving the user experience.

[0146] The channel member 220 can be used to form a steam inlet channel P11 and / or a steam outlet channel P12. One example, as shown in the illustration, is that the channel member 220 and the channel top plate 206 form a steam inlet channel P11; in this case, the channel member 220 is also referred to as the steam inlet channel member 208. Another example, not shown, is that the channel member 220 and the channel top plate 206 form a steam outlet channel P12; in this case, the channel member 220 is also referred to as the steam outlet channel member.

[0147] like Figures 16 to 18 As shown, the channel component 220 includes a plate-shaped body 221 and a sealing portion 222 connected to the plate-shaped body 221. The plate-shaped body 221 is the base part, and the sealing portion 222 is deformable and is the deformable part. The plate-shaped body 221 is arranged, for example, flat on the upper surface of the channel top plate 206, and the plate-shaped body 221 forms the bottom of the channel component 220, forming the bottom wall of the steam channel P1. The lower surface of the plate-shaped body 221 can be attached to the upper surface of the channel bottom plate 205 to generate friction and prevent the channel component 220 from shifting due to deformation. The plate-shaped body 221 is detachably connected to the channel bottom plate 205. Detachably connecting the bottom of the channel component 220 closer to the channel bottom plate 205 to the channel bottom plate 205 allows the connection structure to avoid the deformable part of the channel component 220. The connection structure does not affect the deformation of the channel component 220, thus resulting in a better sealing effect.

[0148] The sealing portion 222 is arranged around the periphery of the plate-shaped body 221 and extends toward the side where the channel top plate 206 is located to form the peripheral wall of the steam channel P1. As a deformable part of the channel member 220, the sealing portion 222 can abut against the channel top plate 206. The sealing portion 222 has a deformable structure; exemplarily, the sealing portion 222 has a lip that adheres to the channel top plate 206. With this configuration, the channel member 220 can maintain good sealing performance with the channel top plate 206 even after multiple disassemblies and reassemblies. The shape of the lip can be V-shaped, Y-shaped, etc.

[0149] For easy disassembly and assembly, the plate-shaped body 221 is provided with at least two mounting holes 223 spaced apart in the first direction, and the passage bottom plate 205 is provided with at least two mounting posts 231 extending upward. The at least two mounting posts 231 correspond to the at least two mounting holes 223, respectively. For example, the passage member 220 has an elongated shape, the first direction is the length direction of the passage member 220, and the at least two mounting holes 223 are arranged in the length direction. In the illustrated example, the passage member 220 is provided with the mounting holes 223 at both ends in the length direction, respectively, and the passage bottom plate 205 is provided with the mounting posts 231 at the corresponding positions, respectively. The plate-shaped body 221 is detachably and compactly sleeved on the mounting posts 231 at the mounting holes 223; the outer surface of the mounting post 231 is tightly fitted with the inner surface of the mounting hole 223 to avoid steam leakage. By directly sleeving the passage member 220 on the mounting post 231, the installation of the passage member 220 is completed, and other components for fixing the passage member 220 are omitted; when the passage member 220 needs to be disassembled, the passage member 220 is separated from the mounting post 231; the installation and disassembly process of the passage member 220 is simple and easy to operate.

[0150] Optionally, as shown in Figure 20 and Figure 21 , 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 on the lower side of the limiting buckle 232 by the limiting buckle 232. By clamping the plate-shaped body 221 by the limiting buckle 232, the passage member 220 is prevented from being separated from the mounting post 231, and the use safety of the passage member 220 is improved. The radial dimension of the limiting buckle 232 is not too large, so that the passage member 220 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 on the mounting post 231.

The communication hole 234 of the first mounting post 231a communicates the steam passage P1 with the cooking cavity, and steam can flow between the cooking cavity and the steam passage P1 via the communication hole 234 of the first mounting post 231a. In the example where the passage member 220 is used to enclose the steam inlet passage P11, a lower end of the communication hole 234 of the first mounting post 231a is formed as the steam inlet port 202, and steam flows from the steam passage P1 into the cooking cavity via the communication hole 234 of the first mounting post 231a. In this example, the at least two mounting posts 231 further include a second mounting post 231b having a communication hole 234 for communicating with the steam generating device 40, and a lower end of the communication hole 234 of the second mounting post 231b is formed as the steam outlet port 201, and steam flows from the steam generating device 40 into the steam passage P1 via the communication hole 234 of the second mounting post 231b. Further, the number of mounting holes 223 is two, and the number of mounting posts 231 is two, and both of the mounting posts 231 have communication holes 234, one of the communication holes 234 of the mounting posts 231 is used to communicate with the cooking cavity, and the other of the communication holes 234 of the mounting posts 231 is used to communicate with the steam generating device 40.

[0152] In the example where the passage member 220 is used to enclose the steam outlet passage P12, a lower end of the communication hole 234 of the first mounting post 231a is formed as the steam outlet port 203, and steam flows from the cooking cavity into the steam passage P1 via the communication hole 234 of the first mounting post 231a. In this way, the mounting posts 231 can be used to both fix the passage member 220 and allow steam to flow, and thus the structure is more optimal.

[0153] Referring to Figure 19 The passage bottom plate 205 is provided with a recess 235 recessed downward from an upper surface of the passage bottom plate 205 so as to form a steam exchange portion 217 protruding downward. The first mounting post 231a extends upward from a bottom of the recess 235. The plate-shaped body 221 is provided with a sleeve 225 connected with the hole edge portion 224 (see Figure 18The sleeve 225 is sleeved on the first mounting column 231a. In this way, the contact area between the sleeve 225 and the first mounting column 231a is large, and the friction generated can limit the downward movement of the plate-shaped body 221, avoiding the influence of the partial downward movement of the plate-shaped body 221 on the sealing effect of the channel member 220. The first mounting column 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 first mounting column 231a protrudes radially outward 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, further avoiding the influence of the partial downward movement of the plate-shaped body 221 on the sealing effect of the channel member 220.

[0154] Optionally, as shown in Figure 20 and Figure 21 , the upper surface of the channel bottom plate 205 is provided with a protruding rib 236 upwardly, and the plate-shaped body 221 is located in the limiting area formed by the protruding rib 236. With the help of the protruding rib 236, the position of the plate-shaped body 221 on the channel bottom plate 205 can be limited, thus playing a role in positioning the channel member 220, avoiding the displacement of the channel member 220 relative to the channel bottom plate 205, thereby avoiding the influence of the local abnormal deformation of the channel member 220 on the sealing effect and preventing steam leakage. The protruding rib 236 is located on both sides of the channel member 220 and extends along the length direction of the channel member 220. The protruding rib 236 extends on the upper surface of the channel bottom plate 205. Optionally, the protruding rib 236 located on one side of the channel member 220 extends around the second mounting column 231b and is connected with the protruding rib 236 located on the other side of the channel member 220. Thus, the second mounting column 231b is located in the limiting area formed by the protruding rib 236. A part of the sealing portion 222 is clamped between the protruding rib 236 and the channel top plate 206. Further, the lip of the sealing portion 222 is clamped between the protruding rib 236 and the channel top plate 206. The sealing portion 222 has a large deformation at the protruding rib 236, which can improve the sealing effect of the channel member 220.
