Generally, the rear end of the lid body 3 is near the pivot 6 between the lid body 3 and the pot body 2.

[0068] In some examples, the lid 3 also includes a removable lid assembly 12. The removable lid assembly 12 is located below the lid body 8 and is manually and detachably connected to the lid body 8 as a component, thus allowing the removable lid assembly 12 to be detachably mounted on the lid 3 from below. When cleaning the removable lid assembly 12 is required, it can be removed from the lid 3. Specifically, the removable lid assembly 12 is located below or inside the liner 9 and is detachably connected to the liner 9. For example, the removable lid assembly 12 is movably connected to the liner 9 via a plug-in and / or snap-fit ​​structure. The removable lid assembly 12 basically includes a lid plate 13, a lid seat 14, and the aforementioned pot opening sealing ring 7. The lid plate 13 may be a metal plate. At least a portion of the lower surface of the lid plate 13 forms the top surface of the food cooking cavity. The lid seat 14 allows the lid plate 13 to be detachably connected to the liner 9. The lid plate 13 can be connected to the lid seat 14 by other suitable means such as snaps or fasteners. A portion of the pot opening sealing ring 7 is pressed between the cover plate 13 and the cover plate seat 14.

[0069] In some alternative examples, the cover 3 includes the aforementioned cover plate 13, which is fixedly connected to the cover body 8, specifically to the liner 9, so that the cover plate 13 is non-removably mounted on the cover 3.

[0070] The pot body 2 basically includes an outer shell 15, a middle plate 16 located on the upper side of the outer shell 15, and a base 17 located on the lower side of the outer shell 15.

[0071] The cooking appliance 1 of this application has a steam supplementary cooking function. High-temperature steam can be delivered to the food cooking chamber to heat and moisten the food inside. For example, during the heat preservation stage, high-temperature steam is supplied to the food cooking chamber to keep foods such as rice moist and prevent them from drying out and turning yellow. Specifically, the cooking appliance 1 also includes a steam generating device 40 for generating supplementary cooking steam to supplement the food cooking chamber. The steam generating device 40 has a steam generating chamber in which the supplementary cooking steam is generated. In order to deliver the supplementary cooking steam to the food cooking chamber, the cover 3 is provided with a supplementary cooking steam supply channel P1, the two ends of which are connected to the steam generating chamber and the food cooking chamber, respectively. The supplementary cooking steam supply channel P1 is used to supply steam for supplementary cooking of the food cooking chamber. Specifically, it can receive supplementary cooking steam from the steam generating device 40 and deliver supplementary cooking steam to the food cooking chamber.

[0072] The steam generating device 40 can be located on the lid 3 or the pot body 2. Figure 1An example of a steam generator 40 disposed in the pot body 2 is shown schematically. The steam generator 40 basically includes a water container 41 and a steam heating base 42. The water container 41 forms a steam generating chamber. The water container 41 is disposed in the pot body 2 and is capable of storing water for generating supplementary cooking steam. The water container 41 has an upper opening for forming an outlet so that the supplementary cooking steam can overflow. The steam heating base 42 is used to heat the water in the water container 41 to generate supplementary cooking steam; it is usually disposed below the water container 41 and has a cavity for receiving the water container 41. The supplementary cooking steam can enter the supplementary cooking steam supply channel P1 and then enter the food cooking chamber to keep food such as rice in the inner pot 4 moist. When the steam generator 40 is disposed in the lid 3, the placement and structure of the water container 41 and the steam heating base 42 are the same as... Figure 1 The examples shown are different.

[0073] 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 As shown, the cover 3 is also provided with a cooking steam exhaust passage P2 for the steam discharged from the food cooking chamber. The two ends of the cooking steam exhaust passage are connected to the food cooking chamber and the external environment, respectively. The cooking steam in the cooking space is discharged to the external environment through the cooking steam exhaust passage P2.

[0074] Optionally, the cooking appliance 1 of this application also has a top heat radiation heating function, whereby the heat generated by the top heat source can radiate to the food inside the food cooking cavity to heat the food from the top side. Specifically, the lid 3 includes a top heating device located in the area of ​​the lid 3 corresponding to the inner pot 4, and the heat generated by the top heating device can be transferred towards the food cooking cavity through heat radiation. The top heating device can be any suitable heating device, such as an electric heating device, an electromagnetic heating device, or an infrared heating device 200. The electric heating device can be a suitable electric heating device such as an electric heating tube, an electric heating wire, or an electric heating film. The illustrated example schematically shows the top heating device as an infrared heating device 200, used to radiate infrared rays into the food cooking cavity during the cooking process. The infrared rays radiated into the food cooking cavity can effectively heat the surface food, making the food evenly heated, thereby stimulating the aroma of the food.

[0075] For the infrared heating device 200, the cover plate 13 is partially provided with a cover plate through hole 19. The cover plate through hole 19 corresponds to the position of the infrared heating device 200. In other words, the cover plate through hole 19 is located directly below the infrared heating device 200. The infrared rays generated by the infrared heating device 200 can radiate towards the inner pot 4 through the cover plate through hole 19. The cover body 3 may also include a through hole sealing ring 22. The through hole sealing ring 22 can be disposed around the cover plate through hole 19 and is located on the side of the cover plate through hole 19 opposite to the side where the pot opening sealing ring 7 is located, specifically between the infrared heating device 200 and the inner liner 9. Forming a seal at the cover plate through hole 19 can prevent steam from entering the interior of the cover body 3 through the gap between the infrared heating device 200 and the cover plate 13, thereby improving the sealing effect of the cover body 3.

[0076] The following text combines Figures 1 to 12 The specific structure of the steam supply channel P1 for supplementary cooking is described.

[0077] like Figures 1 to 4 As shown, the cover 3 also includes a steam channel assembly 100 for forming a supplementary steam supply channel P1. The steam channel assembly 100 is located above the cover plate 13 and below the liner 9. The steam channel assembly 100 is arranged horizontally parallel to the top heating device, for example, located behind the top heating device. The steam channel assembly 100 is mounted on the removable cover assembly 12, and the two form a single unit. The removable cover assembly 12 with the steam channel assembly 100 is detachably connected to the cover body 8. Thus, the steam channel assembly 100 can be removed from the cover 3 along with the removable cover assembly 12 to clean the supplementary steam supply channel P1 on the steam channel assembly 100. The cover plate through-hole 19 is located near the front end of the removable cover assembly 12. The steam channel assembly 100 is located near the rear end of the removable cover assembly 12. The cover plate through hole 19 and the steam channel assembly 100 can be arranged in a front-to-back manner, with the cover plate through hole 19 in front and the steam channel assembly 100 in the back, so that the cover plate through hole 19 can be designed to occupy a larger cooking area and increase the infrared radiation area.

[0078] For cooking appliances 1 that do not have an infrared heating device 200, the steam channel assembly 100 can be located near the rear end or middle of the removable cover assembly 12, and inject supplementary steam from the rear end or middle of the cover plate 13 into the food cooking chamber.

[0079] like Figures 5 to 10 As shown, the steam passage assembly 100 can be arranged generally in a horizontal direction. The steam passage assembly 100 includes a generating end component 110, a transmission passage component 120, and an output end component 130. The transmission passage component 120 has a passage steam inlet end 123 and a passage steam outlet end 124.

[0080] One end of the generating end component 110 is connected to the steam generating chamber of the steam generating device 40, and the other end of the generating end component 110 is inserted into, overlapped with, or directly connected to the steam inlet end 123 of the channel. The generating end component 110 and the steam generating device 40 (steam generating chamber) are in sealed communication, that is, a sealed channel is formed between the two. Thus, the supplementary cooking steam in the steam generating chamber can flow through the generating end component 110 and enter the transmission channel component 120 through the steam inlet end 123 for transmission.

[0081] One end of the output component 130 is inserted into, overlapped with, or directly connected to the steam outlet 124 of the channel, while the other end of the output component 130 is used to communicate with the food cooking chamber. The output component 130 and the food cooking chamber are in a sealed communication, forming a sealed channel between them. Thus, the supplementary cooking steam, after being transmitted through the transmission channel component 120, enters the food cooking chamber via the steam outlet 124 and the output component 130.

[0082] The transmission channel component 120 is located between the generating end component 110 and the output end component 130, and the channel steam inlet 123 and the channel steam outlet 124 are respectively sealed and connected to the generating end component 110 and the output end component 130. The channel steam inlet 123 is inserted into, overlapped with or directly connected to the generating end component 110, and the channel steam outlet 124 is inserted into, overlapped with or directly connected to the output end component 130.

[0083] It should be noted that "insertion" can be understood as the end of one component being inserted into the port of another component, at which point a seal is formed between the outer circumferential surface of the inserted end and the inner circumferential surface of the port; "lap joint" can be understood as one component having a boss protruding from its end face, and the end of another component lapping on the upper surface of the boss, at which point the end faces of the two ends abut and form a seal; "butt joint" can be understood as the end of one component abutting the end of another component at both end faces, at which point the end faces of the two ends form a seal.

[0084] Specifically, such as Figure 6 As shown, the generating end member 110 has a generating end steam inlet 111, which is used to dock with the steam generating device 40, that is, the generating end steam inlet 111 is used to connect with the steam generating chamber. The generating end steam inlet 111 faces vertically. In the illustrated example, the generating end steam inlet 111 is located at the bottom end of the generating end member 110 and faces downward so as to dock with the steam generating device 40 located in the pot body 2. Alternatively, the generating end steam inlet 111 is located at the top end of the generating end member 110 and faces upward so as to dock with the steam generating device 40 located in the cover body 3. The generating end member 110 is described herein with reference to illustrated examples.

[0085] like Figure 9 and Figure 10As shown, the generating end component 110 has a generating end steam outlet 112, which faces horizontally. The generating end steam outlet 112 is connected to the channel steam inlet 123 by a plug-in, overlap, or opposite connection. For example, the channel steam inlet 123 is plugged into the generating end steam outlet 112.

[0086] The output end component 130 is provided with an output end supplementary steam inlet 132, an output end supplementary steam outlet 131, and an output end cooking steam inlet 133. The output end supplementary steam inlet 132 is connected to the channel steam outlet 124 by a butt joint, overlap, or insertion method. For example, the channel steam outlet 124 is inserted into the output end supplementary steam inlet 132. The output end supplementary steam outlet 131 is used to communicate with the food cooking chamber, and the output end supplementary steam outlet 131 faces downward to spray supplementary steam downward toward the food cooking chamber. The output end cooking steam inlet 133 is used to communicate with the food cooking chamber so that cooking steam in the cooking space can be discharged.

[0087] A steam channel assembly 100 spans between the cover plate 13 and the cover plate seat 14. A generating end component 110 is connected to the cover plate seat 14, an output end component 130 is connected to the cover plate 13, and a transmission channel component 120 spans between the cover plate 13 and the cover plate seat 14. A steam generating device 40 is located at the rear corner of the pot body 2, and correspondingly, the generating end component 110 is located at the rear corner of the cover body 3. This allows the position of the generating end steam inlet 111 to correspond vertically with the water container 41 of the steam generating device 40, enabling steam to enter the generating end steam inlet 111 from bottom to top, resulting in a short and direct steam path between the generating end steam inlet 111 and the water container 41. When the cover body 3 is closed on the pot body 2, the generating end component 110 abuts against the periphery of the upper opening of the water container 41. The generating end component 110 can seal the upper opening of the steam generating device 40 to prevent the steam from leaking outwards. The opening and closing action of the generating end component 110 on the steam generating device 40 of the pot body 2 is achieved by opening and closing the lid 3, which reduces the user's operation steps and improves the user's operating experience.

[0088] The supplementary steam outlet 131 is located at the front end of the steam channel assembly 100. Optionally, the supplementary steam outlet 131 is located near or on the longitudinal centerline of the cover plate 13. Optionally, the output end member 130 is located at the rear end of the cover plate 13, so that the supplementary steam outlet 131 is located at the rear end of the cover plate 13. Alternatively, the output end member 130 is located in the middle of the cover plate 13, so that the supplementary steam outlet 131 is located in the middle of the cover plate 13.

[0089] like Figure 7 and Figure 10As shown, the supplementary cooking steam supply channel P1 extends between the generating end steam inlet 111 and the output end supplementary cooking steam outlet 131. Specifically, the generating end component 110 forms a supplementary cooking steam input section channel P11 communicating with the generating end steam inlet 111, the transmission channel component 120 forms a supplementary cooking steam transmission section channel P12, and the output end component 130 forms a supplementary cooking steam output section channel P13 communicating with the output end supplementary cooking steam outlet 131. The supplementary cooking steam output section channel P13 is located between the output end supplementary cooking steam inlet 132 and the output end supplementary cooking steam outlet 131. The supplementary cooking steam output section channel P13 is connected to the supplementary cooking steam input section channel P11 through the supplementary cooking steam transmission section channel P12. Supplementary cooking steam enters the supplementary cooking steam input section channel P11 from the generating end steam inlet 111, flows through the supplementary cooking steam transmission section channel P12, and then flows into the supplementary cooking steam output section channel P13 before being ejected from the output end supplementary cooking steam outlet 131 and entering the cooking space.

[0090] The steam passage assembly 100 is detachably connected to the removable cover assembly 12. Specifically, the generating end component 110 is detachably connected to the cover seat 14, allowing the generating end component 110 to be removed from the removable cover assembly 12 for cleaning the supplementary steam input section passage P11. The transmission passage component 120 is detachably connected to the cover seat 14. The transmission passage component 120 occupies an area on the cover seat 14 for installation, reducing the area ratio of the steam passage assembly 100 on the cover 13; the transmission passage component 120 is detachable, facilitating assembly and replacement. The output end component 130 is detachably connected to the cover seat 14, allowing the output end component 130 to be removed from the removable cover assembly 12 for cleaning the supplementary steam output section passage P13.

[0091] like Figure 8 and Figure 10 As shown, the cover plate seat 14 is provided with a cover plate seat mounting hole 20. The generating end component 110 of the steam channel assembly 100 passes through the cover plate seat mounting hole 20 and can be snapped onto the edge of the cover plate seat mounting hole 20. The generating end component 110 can be detachably installed onto the cover plate 13 by snapping, and the disassembly and assembly process is simple and easy to operate, facilitating the separate removal of the generating end component 110 for cleaning. The cover plate 13 is provided with a cover plate mounting hole 21. The output end component 130 passes through the cover plate mounting hole 21 and can be snapped onto the edge of the cover plate mounting hole 21. The output end component 130 can be detachably installed onto the cover plate 13 by snapping, and the disassembly and assembly process is simple and easy to operate, facilitating the separate removal of the output end component 130 for cleaning.

[0092] The shape of the cover plate mounting hole 20 corresponds to the shape of the steam inlet 111 at the generating end, and the shape of the cover plate mounting hole 21 corresponds to the shape of the supplementary steam outlet 131 at the output end. For example, if the steam inlet 111 at the generating end and the supplementary steam outlet 131 at the output end are circular, the cover plate mounting hole 20 and the cover plate mounting hole 21 are also circular. In this way, the structure of the inner side of the cover body 3 (the side facing the inner pot 4 when the cover is closed) is neat, which can improve the overall appearance of the inner side of the cover body 3.

[0093] The cover plate 13 and / or cover plate seat 14 are provided with support members 23. For the illustrated example, as shown... Figure 8 and Figure 9 As shown, the cover plate seat 14 is provided with a support member 23, which protrudes upward from the upper surface of the main body of the cover plate seat 14. The transmission channel member 120 is provided with a channel connector 121. The channel connector 121 is integrally disposed in approximately the middle of the transmission channel member 120. The channel connector 121 is detachably connected to the support member 23, thereby detachably mounting the transmission channel member 120 to the cover plate seat 14. For example, the channel connector 121 is connected to the support member 23 by fasteners such as screws and / or snap-fits, so that the transmission channel member 120 is non-removably detachable / movably detachable. Alternatively, the channel connector 121 is connected to the support member 23 by a non-removable method such as welding or riveting.

[0094] Optionally, the support member 23 is integrally formed on the cover plate seat 14. If needed and / or desired, the support member 23 is a separate member that is connected to the cover plate seat 14 by welding, fasteners such as screws, snap-fit, plug-in or other suitable means; the channel connector 121 is a separate member that is connected to the transmission channel member 120 by welding, fasteners such as screws, snap-fit, plug-in or other suitable means.

[0095] The supplementary cooking steam input channel P11 extends between the generator steam inlet 111 and the generator steam outlet 112. Optionally, the output supplementary cooking steam inlet 132 faces horizontally. The supplementary cooking steam output channel P13 extends between the output supplementary cooking steam outlet 131 and the output supplementary cooking steam inlet 132.

[0096] The transmission channel component 120 also includes a hollow channel component body 122. A steam inlet 123 is connected to one end of the channel component body 122, and a steam outlet 124 is connected to the other end of the channel component body 122. The steam inlet 123 extends along a first direction and has a first port 125, and the steam outlet 124 extends along the first direction and has a second port 126. The supplementary steam transmission section P12 extends between the first port 125 and the second port 126. Therefore, the transmission channel component 120 independently forms the supplementary steam transmission section P12, eliminating the need for assembling multiple components. When assembling the supplementary steam transmission section P12 into the cooking appliance 1, only the steam channel component itself needs to be assembled, making the assembly process simple.

[0097] The first direction is horizontal or the angle between the steam inlet 123 and the steam outlet 124 is less than or equal to 5°. That is, the steam inlet 123 and the steam outlet 124 of the passage are set to extend approximately horizontally. In this way, the transmission passage component 120 is horizontally connected, inserted, or overlapped with other components in the cooking appliance 1, which helps to reduce the vertical dimension of the steam passage assembly 100.

[0098] The steam inlet 123 of the channel is detachably plugged into, overlapped with or docked with the steam outlet 112 of the generating end component 110. The steam outlet 124 of the channel is detachably plugged into, overlapped with or docked with the supplementary steam inlet 132 of the output end component 130.

[0099] The detachable connection between the generating end component 110 / output end component 130 and the transmission channel component 120 can be a plug-in connection as shown in the figure, in which case the sealed connection between the two is more stable and reliable; or it can be a butt joint, in which case the generating end component 110 / output end component 130 is provided with a deformation structure at the interface to seal and connect with the transmission channel component 120, resulting in a better sealing effect.

[0100] The illustration shows that the two ends of the transmission channel component 120 are connected to the generating end component 110 and the output end component 130 via interfaces, respectively. Specifically, the channel steam inlet 123 is connected to the generating end steam outlet 112; the channel steam outlet 124 is connected to the output end supplementary steam inlet 132.

[0101] Optionally, the generating end component 110 includes a generating end supplementary steam connection 113, which has a preset length, for example, extending a preset length horizontally. The port of the generating end supplementary steam connection 113 constitutes the generating end steam outlet 112. The generating end supplementary steam connection 113 can receive a portion of the transmission channel component 120, increasing the sealing area between the generating end supplementary steam connection 113 and the transmission channel component 120, thereby improving the sealing effect. The generating end supplementary steam connection 113 extends horizontally, facilitating horizontal docking, overlapping, or insertion between the transmission channel component 120 and the generating end component 110, which helps to reduce the vertical dimensions of the steam channel assembly 100.

[0102] The output end component 130 includes an output end supplementary steam connection portion 135, which has a preset length, for example, extending a preset length horizontally. The port of the output end supplementary steam connection portion 135 constitutes an output end supplementary steam inlet 132. The output end supplementary steam connection portion 135 can receive a portion of the transmission channel component 120, increasing the sealing area between the output end supplementary steam connection portion 135 and the transmission channel component 120, thereby improving the sealing effect. The output end supplementary steam connection portion 135 extends horizontally, facilitating horizontal docking, insertion, or overlap between the transmission channel component 120 and the output end component 130, which helps to reduce the vertical dimension of the steam channel assembly 100.

[0103] Optionally, the generating end component 110 is made of an elastically deformable material. Optionally, the output end component 130 is made of an elastically deformable material. The generating end component 110 and the output end component 130, both made of elastically deformable materials, have a certain elastic deformation capability, resulting in better sealing and a more durable seal at the junction of the generating end component 110 and the food cooking cavity and the transmission channel component 120, and at the junction of the output end component 130 and the food cooking cavity and the transmission channel component 120.

[0104] Optionally, the generating end component 110 is made of silicone rubber. Optionally, the output end component 130 is made of silicone rubber. The silicone rubber generating end component 110 and output end component 130, in addition to their sealing capabilities, primarily possess structural strength and support capabilities, stably supporting the transmission channel component 120 at the joint. This enhances the stability of the sealed connection between the generating end component 110 and the transmission channel component 120, and between the output end component and the transmission channel component 120, preventing leakage. Furthermore, the complex structure of the steam generating end component 110 and output end component 130 allows for forced demolding during silicone rubber injection molding, ensuring successful production of the finished product. Silicone rubber possesses characteristics such as long-term resistance to high-temperature moisture, odorlessness, low cost, reliable mass production processes, good structural plasticity, and excellent long-term sealing performance.

[0105] like Figure 11 As shown, the ends of the steam inlet 123 and / or the steam outlet 124 of the transmission channel are provided with guide surfaces 127, which extend circumferentially along the transmission channel member 120. The guide surfaces 127 are inclined to the outer peripheral surfaces of the steam inlet 123 and / or the steam outlet 124, and are inclined towards the central axis of the steam inlet 123 and / or the steam outlet 124 in the direction near the port. The guide surfaces 127 provide guidance when the steam inlet 123 and / or the steam outlet 124 are inserted with other components, facilitating the connection.

[0106] like Figure 12 As shown, the steam inlet 123 and steam outlet 124 of the channel constitute a tubular section, and the outer cross-sectional dimension D3 of the tubular section is smaller than the outer cross-sectional dimension D2 of the main body 122 of the channel component. For example, the steam inlet 123 and steam outlet 124 of the channel are in the shape of a circular tube, and the outer cross-sectional dimension is the outer diameter of the circular tube. The size design of the steam inlet 123 and steam outlet 124 of the channel facilitates insertion with the sealing element.

[0107] Optionally, the steam inlet 123 of the transmission channel member 120 has a dimension L1 along its length. The steam outlet 124 of the transmission channel member 120 also has a dimension L1 along its length. Dimension L1 is 5mm to 20mm. For example, the dimension L1 of the steam inlet 123 and / or the steam outlet 124 can be a suitable value such as 5mm, 6mm, 8mm, 10mm, 15mm, 18mm, or 20mm. Thus, the steam inlet 123 can be inserted to a certain length into the supplementary steam connection 113 at the generating end, which improves the sealing of the connection between the steam inlet 123 and the supplementary steam connection 113. The steam outlet 124 can be inserted to a certain length into the supplementary steam connection 135 at the output end, which also improves the sealing of the connection between the steam outlet 124 and the supplementary steam connection 135. The dimension L1 of the steam inlet 123 and the dimension L1 of the steam outlet 124 can be different or the same.

[0108] The transmission channel component 120 is an integral tubular component, and the main body 122, the steam inlet 123, and the steam outlet 124 are all integral components. In this way, the transmission channel component 120 can form a circumferentially sealed first supplementary cooking steam channel, so that no additional sealing element is required; the construction of the supplementary cooking steam supply channel P1 is simple.

[0109] The transmission channel component 120 extends along a reference straight line L. In other words, the central axis of the tubular transmission channel component 120 lies on the reference straight line L, or the extension direction of the tubular transmission channel component 120 extends along the reference straight line L, thus making the supplementary cooking steam transmission section channel P12 a straight channel. The straight transmission channel component 120 shortens the flow distance and time of the supplementary cooking steam, thereby quickly supplying supplementary cooking steam to the food cooking chamber and reducing energy loss. Structurally, it is easy to manufacture and occupies less internal space in the cover 3, which is beneficial to the miniaturization of the cover 3.

[0110] See Figure 5 The transmission channel component 120 is inclined relative to the longitudinal centerline of the cover plate 13. In other words, the reference line L / central axis / extension direction of the transmission channel component 120 has a predetermined angle with the centerline extending in the front-rear direction of the cover plate 13. It should be noted that the "longitudinal centerline" refers to a straight line extending in the longitudinal direction and passing through the center of the component. For example, the longitudinal centerline of the cover plate 13 extends in the longitudinal direction and passes through the center of the cover plate 13; the term "longitudinal" as used herein refers to the front-rear direction, and "lateral" refers to the left-right direction.

[0111] The cross-sectional shape of the steam transmission channel P12 for supplementary cooking is a regular or semi-regular shape. Regular shapes include circles, ellipses, and polygons, while semi-regular shapes include polygons with rounded corners. Polygons can be squares, trapezoids, etc.

[0112] Optionally, the cross-sectional shape of the supplementary cooking steam transmission section P12 is circular, and the diameter (inner diameter of the transmission channel component 120) D1 of the supplementary cooking steam transmission section P12 is 2mm to 8mm. For example, the diameter D1 of the supplementary cooking steam transmission section P12 can be a suitable size such as 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 7mm, 7.5mm, or 8mm. This size design can ensure the steam flow efficiency of the supplementary cooking steam transmission section P12, and the size of the transmission channel component 120 is appropriate.

[0113] Preferably, the transmission channel component 120 is made of a rigid material, including plastic materials such as PP (polypropylene), PE (polyethylene), PET (polyethylene terephthalate), PS (polystyrene), etc. In this way, the transmission channel component 120 is less susceptible to deformation due to compression, thus eliminating the need for a housing 15 for protection, requiring fewer parts, and simplifying assembly. If required and / or desired, the transmission channel component 120 may be made of a soft material, such as silicone rubber.

[0114] Optionally, the transmission channel component 120 is made of a transparent or translucent material, which allows the user to observe the cleanliness of the steam transmission section P12 when cleaning the transmission channel component 120.

[0115] To allow cooking steam in the cooking space to escape to the outside, the output end component 130 also forms a cooking steam exhaust channel P21 for the passage of cooking steam. The cooking steam exhaust channel P21 originates from the output end cooking steam inlet 133. Cooking steam can be exhausted to the external environment via the cooking steam exhaust channel P21. The output end component 130 also forms an output end cooking steam outlet 134. The cooking steam exhaust channel P21 extends between the output end cooking steam inlet 133 and the output end cooking steam outlet 134. The cooking steam exhaust channel P2 includes the cooking steam exhaust channel P21. The cooking steam exhaust channel P21 is independent of the supplementary cooking steam output section channel P13. Preferably, the supplementary cooking steam output section channel P13 is arranged substantially parallel to the cooking steam exhaust channel P21.

[0116] This design creates a dual-channel system with a single seal, delivering both supplementary steam and cooking steam separately. This dual-purpose design allows the two channels to occupy the same area of ​​the cover 3, minimizing internal space and reducing the number of parts, thus promoting miniaturization and improving space utilization. Furthermore, the cooking steam exhaust channel P21 has a higher temperature, and the adjacent supplementary steam output channel P13 maintains an even higher temperature. This minimizes heat loss as the supplementary steam enters the food cooking chamber through the supplementary steam supply channel P1, resulting in higher steam temperatures and better supplementary cooking. Additionally, it prevents condensation during transmission through the supplementary steam output channel P13, avoiding water droplets that could affect the supplementary cooking effect. The output component 130 simultaneously seals both the cooking steam inlet 133 and the supplementary steam outlet 131. This multi-functional design reduces heat loss during steam transmission, effectively ensuring optimal moisture retention for foods such as rice.

[0117] It should be noted that the term "approximately" used to describe the orientation of components above means that there is a fluctuation of ±5° relative to the specified direction. For example, "approximately parallel" to the first and second components means that the angle between the central axis of the first component and the central axis of the second component is within ±5°.

[0118] See back Figure 1 and Figure 3The cooking steam exhaust passage P2 also includes a cooking steam discharge passage P22. The cooking steam discharge passage P21 connects to the food cooking chamber. Cooking steam first enters the cooking steam discharge passage P21 and then exits to the external environment via the cooking steam discharge passage P22. The cover 3 also includes a steam valve 31 and a cooking steam passage component 32 forming the cooking steam discharge passage P22. The cooking steam passage component 32 is located below the steam valve 31 and above the output end component 130. The cooking steam passage component 32 is fixed to the upper side of the inner liner 9. The cooking steam passage component 32 abuts against the output end component 130 to form a sealed connection. A passage seal 33 is provided between the steam valve 31 and the cooking steam passage component 32 to form a sealed connection. See also Figure 3 The cover 3 also includes a temperature detection device 34 for detecting the temperature of the cooking steam. Optionally, the temperature detection device 34 is disposed on the cooking steam passage component 32 and its detection end is located in the cooking steam exhaust passage P22.
