Description

Technical Field

[0001] This application relates to the technical field of kitchen appliances, and more specifically to a removable cover assembly, a cover body, and a cooking utensil. Background Technology

[0002] Existing steam cooking appliances, such as steam rice cookers, generally have a steam inlet channel and a steam outlet channel inside the lid. The steam inlet channel delivers high-temperature steam from the steam source to the cooking chamber, while the steam outlet channel allows the steam inside the cooking chamber to be discharged to the outside environment. During the cooking stage, the high-temperature steam generated by the steam source is introduced into the cooking chamber through the steam inlet channel, which heats and moistens the food inside the cooking chamber.

[0003] The steam inlet and steam outlet channels are formed by connecting an upper and lower cover. However, the upper cover of the steam inlet channel and the upper cover of the steam outlet channel are located separately in different positions. As a result, these two channels occupy a large space in the cover body, making the cover structure complex and the assembly process cumbersome.

[0004] Therefore, a removable cover assembly is needed to at least partially solve the above problems. Utility Model Content

[0005] The description of this utility model introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This description is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0007] According to this solution, the steam output channel for supplementary cooking and the steam input channel for cooking are cleverly designed together in a relatively small area, so that the structure constituting these two steam channels can be set up more compactly, reducing the space occupied on the detachable lid assembly. This results in a smaller internal space occupied by the lid, which is conducive to the miniaturization of the lid and improves the utilization rate of the internal space of the lid. In addition, it is beneficial for the steam channels to occupy a smaller cooking area on the detachable lid assembly, and the spatial layout of the detachable lid assembly is reasonably adjusted.

[0008] Optionally, the detachable cover assembly includes a steam channel assembly, with the steam channels centrally distributed in the front region of the steam channel assembly. According to this design, the longitudinal space of the steam channel assembly can be better utilized to arrange steam channels with longer extension paths, thus miniaturizing the longitudinal dimensions of the steam channel assembly.

[0042] like Figures 1 to 4 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 to facilitate cleaning of the inner pot 4. 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. It is understood that the cooking appliance 1 according to this application can be a rice cooker, an electric pressure cooker, or other cooking appliances 1, and the cooking appliance 1 can have various functions such as cooking porridge in addition to cooking rice.

[0043] The lid 3 has a shape substantially corresponding to the pot body 2. The lid 3 is closable on the pot body 2. In one example, the lid 3 is pivotally connected to the pot body 2 via a pivot axis 6 and can pivot freely about the pivot axis 6 line relative to the pot body 2 between a closed position and an open position, facilitating the closing and opening of the pot body 2. In another example, the lid 3 and pot body 2 are connected by interlocking and easily disassembled fasteners, so that they are tightly connected during cooking and can be separated into two independent units, for example, during cleaning. When the lid 3 is closed on the pot body 2, it covers the inner pot 4, forming a cooking cavity between them. The lid 3 typically also has a pot opening sealing ring 7, which can be made of, for example, rubber material, and is positioned between the lid 3 and the inner pot 4 to seal the cooking cavity when the lid 3 is closed.

[0044] It should be noted that the directional terms used in this article to describe the various parts and components of the cooking appliance 1, such as "up", "down", "above", "below", "upward", "downward", "facing upward", and "facing downward", are relative to the cooking appliance 1 when it is placed horizontally, upright, and the lid 3 is closed.

[0045] The lid body 3 basically includes the lid body 8. The lid body 8 includes an inner liner 9 and a cover assembly 10. The cover assembly 10 is located on the upper side or outer side of the inner liner 9 and can cover the inner liner 9. The upper surface of the cover assembly 10 has a user interaction area for user operation. The inner liner 9 can be connected to the cover assembly 10 by a suitable method such as snap-fit, fastener connection such as screws, or adhesive. The pivot 6 is located in the inner liner 9 and is fitted with a torsion spring 11 for automatic lid opening. The pot body 2 also includes a lid opening button, and the lid body 3 has a lid opening hook 18. By pressing the lid opening button, the lid opening hook 18 is released. The end of the lid body 3 with the lid opening hook 18 or near the lid opening button is the front end, and the opposite end of the front end is the rear end. Generally, the rear end of the lid body 3 is near the pivot 6 between the lid body 3 and the pot body 2.

[0046] 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 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.

[0047] 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.

[0048] 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. The lower end of the outer shell 15 can be connected to the outer periphery of the middle plate 16 by a suitable method such as snap-fit, fastener connection such as screws, or bonding, and the lower end of the outer shell 15 can be connected to the upper end of the base 17 by a suitable method such as snap-fit, fastener connection such as screws, or bonding.

[0049] The cooking appliance 1 of this application has a steam supplementary cooking function. High-temperature steam can be delivered to the food cooking cavity to heat and moisten the food inside. For example, during the heat preservation stage, high-temperature steam can be introduced into the food cooking cavity 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 generator 40 for generating supplementary cooking steam to supplement the cooking of the food cooking cavity. In order to deliver the supplementary cooking steam to the food cooking cavity, the cover 3 is provided with a supplementary cooking steam channel P1 communicating with the food cooking cavity. The supplementary cooking steam channel P1 is used for the passage of steam for supplementary cooking of the food cooking cavity. Specifically, it can receive supplementary cooking steam from the steam generator 40 and deliver supplementary cooking steam to the food cooking cavity.

[0050] The steam generating device 40 can be located on the lid 3 or the pot body 2. Figure 1 An example of a steam generator 40 disposed in the pot body 2 is shown schematically. Figure 4As shown, the steam generator 40 includes a steam generating chamber with an upper opening. The steam generator 40 basically includes a water container 41 and a steam generating heating base 42. 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 forms the steam generating chamber, with its upper opening for the overflow of supplementary cooking steam. The steam generating heating base 42 is used to heat the water in the water container 41 to generate supplementary cooking steam; and is generally disposed below the water container 41 and has a cavity for receiving the water container 41. This supplementary cooking steam can enter the supplementary cooking steam passage 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 body 3, the placement and structure of the water container 41 and the steam generating heating base 42 are the same as... Figure 1 The examples shown are different.

[0051] 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 1 and Figure 3 As shown, the cover 3 is also provided with a cooking steam exhaust channel P2 for the steam discharged from the food cooking chamber to pass through.

[0052] The cooking appliance 1 of this application also has a top-heating function, whereby the heat generated by the top heat source can radiate to the food inside the cooking cavity, heating the food from the top. 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 cooking cavity via 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 cooking cavity during the cooking process. The infrared rays radiated into the cooking cavity can effectively heat the surface of the food, making the food evenly heated, thereby stimulating the aroma of the food.

[0053] 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 located on the side 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.

[0054] The following text combines Figures 1 to 15 The structure of the steam passage P1 for supplementary cooking is described in detail.

[0055] like Figures 1 to 4 As shown, the lid 3 also includes a steam channel assembly 100 for forming a supplementary steam channel P1. The steam channel assembly 100 is located on the upper side of the lid 13 and the lower side of the liner 9. The steam channel assembly 100 is arranged horizontally parallel to the top heating device, specifically on the rear side of the top heating device. The steam channel assembly 100 is mounted on the removable lid assembly 12, forming a single unit, and the removable lid assembly 12 with the steam channel assembly 100 is detachably connected to the lid body 8. Thus, the steam channel assembly 100 can be removed from the lid 3 along with the removable lid assembly 12 to clean the supplementary steam channel P1 on the steam channel assembly 100. The lid through-hole 19 is located near the front end of the removable lid assembly 12. The steam channel assembly 100 is located near the rear end of the removable lid assembly 12. The lid 13 defines a cooking area within the pot opening sealing ring 7. 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.

[0056] 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.

[0057] like Figures 5 to 10 As shown, the steam passage assembly 100 is arranged horizontally. The steam passage assembly 100 includes a steam generating end component 110, a transmission passage component 120, and an output end component 130 for the passage of supplemental cooking steam. The transmission passage component 120 is located between the steam generating end component 110 and the output end component 130, and its two ends are respectively sealed and connected to the steam generating end component 110 and the output end component 130. The steam generating end component 110 is sealed and connected to the steam generating device 40, forming a sealed passage between them. The output end component 130 is sealed and connected to the food cooking chamber, forming a sealed passage between them. The transmission passage component 120 is sealed and connected to both the steam generating end component 110 and the output end component 130.

[0058] Specifically, such as Figure 6As shown, the steam generating end member 110 has a supplementary steam inlet 111 for docking with the steam generating device 40. The supplementary steam inlet 111 faces vertically. In the illustrated example, the supplementary steam inlet 111 is located at the bottom end of the steam generating end member 110 and faces the steam generating device 40, for example, downwards, so as to dock with the steam generating device 40 located in the pot body 2. Alternatively, the supplementary steam inlet 111 is located at the top end of the steam generating end member 110 and faces upwards, so as to dock with the steam generating device 40 located in the lid body 3. The steam generating end member 110 is described herein with reference to the illustrated example. The output end member 130 has a supplementary steam outlet 131 for communicating with the food cooking chamber. The supplementary steam outlet 131 faces downwards to spray supplementary steam downwards into the food cooking chamber.

[0059] A steam passage assembly 100 is detachably mounted across the cover plate 13 and the cover plate seat 14. A steam 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 passage component 120 is detachably mounted across both 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 a steam generating end component 110 is located at the rear corner of the cover body 3, specifically at the rear corner of the cover plate seat 14, thus the supplementary cooking steam inlet 111 is located at the corner of the cover body 3. This allows the position of the supplementary cooking steam inlet 111 to correspond vertically with the water container 41 of the steam generating device 40, allowing steam to enter the supplementary cooking steam inlet 111 from bottom to top, resulting in a shorter and more direct steam path between the supplementary cooking steam inlet 111 and the water container 41. The steam generating end component 110 abuts against the periphery of the upper opening when the cover body 3 is closed onto the pot body 2. The steam 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 of the steam generating device 40 of the pot body 2 by the steam generating end component 110 is achieved by opening and closing the lid 3, which reduces the user's operation steps and improves the user's operating experience.

[0060] The supplementary steam outlet 131 is located at the front end of the steam passage 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 of the cover plate 13, thereby the supplementary steam outlet 131 is located at the rear of the cover plate 13. Alternatively, the output end member 130 is located at the middle of the cover plate 13, thereby the supplementary steam outlet 131 is located at the middle of the cover plate 13.

[0061] like Figure 7 and Figure 10As shown, the supplementary cooking steam passage P1 extends between the supplementary cooking steam inlet 111 and the supplementary cooking steam outlet 131. Specifically, the steam generating end component 110 is a single-piece hollow component, for example, a single-piece hollow component made of an elastic material. The transmission channel component 120 is a component with a cylindrical channel. The output end component 130 is a single-piece hollow component, for example, a single-piece hollow component made of an elastic material. The steam generating end component 110 forms a supplementary cooking steam input passage P11 with a supplementary cooking steam inlet 111, the transmission channel component 120 forms a supplementary cooking steam transmission passage P12, and the output end component 130 forms a supplementary cooking steam output passage P13 with a supplementary cooking steam outlet 131. The supplementary cooking steam output passage P13 is connected to the supplementary cooking steam input passage P11 through the supplementary cooking steam transmission passage P12. The supplementary cooking steam enters the supplementary cooking steam input channel P11 from the supplementary cooking steam inlet 111, flows through the supplementary cooking steam transmission channel P12, and then flows into the supplementary cooking steam output channel P13 before being ejected from the supplementary cooking steam outlet 131.

[0062] The steam passage assembly 100 is detachably connected to the removable cover assembly 12. Specifically, the steam generating end component 110 is detachably connected to the cover plate seat 14, allowing the steam generating end component 110 to be removed from the removable cover assembly 12 for cleaning the supplementary cooking steam input passage P11. The transmission passage component 120 is detachably connected to the cover plate seat 14. The transmission passage component 120 occupies an area on the cover plate seat 14 for installation, reducing the area ratio of the steam passage assembly 100 on the cover plate 13; and the transmission passage component 120 is detachable, facilitating assembly and replacement. The output end component 130 is detachably connected to the cover plate 13, allowing the output end component 130 to be removed from the removable cover assembly 12 for cleaning the supplementary cooking steam output passage P13.

[0063] like Figure 8 and Figure 10 As shown, the cover plate seat 14 has a cover plate seat mounting hole 20. The steam 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 steam 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 steam generating end component 110 for cleaning. The cover plate 13 has a cover plate mounting hole 21. The output end component 130 is detachably inserted into the cover plate mounting hole 21, for example, the output end component 130 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.

[0064] The shape of the cover plate mounting hole 20 corresponds to the shape of the supplementary steam inlet 111, and the shape of the cover plate mounting hole 21 corresponds to the shape of the supplementary steam outlet 131. For example, if the supplementary steam inlet 111 and the supplementary steam outlet 131 are circular, the cover plate mounting hole 20 and the cover plate mounting hole 21 are also circular. The neat structure of the inner side of the cover body 3 can improve the overall appearance of the inner side of the cover body 3 in terms of shape.

[0065] 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 cover plate seat 14. The transmission channel member 120 is provided with a channel connector 121. The channel connector 121 is integrally disposed on the transmission channel member 120, for example, connected to its generally central portion. The channel connector 121 can be connected to the support member 23, and the illustration shows its detachable connection to the support member 23, so that the transmission channel member 120 is detachably connected to the cover plate seat 14 and / or the cover plate 13 through the detachable connection between the channel connector 121 and the support member 23. 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.

[0066] Optionally, the support member 23 is integrally formed on the cover plate seat 14; the channel connector 121 is integrally formed on the transmission channel member 120. If needed and / or desired, the support member 23 is a separate member 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 connected to the transmission channel member 120 by welding, fasteners such as screws, snap-fit, plug-in or other suitable means.

[0067] The steam generating end component 110 has a first supplementary cooking steam inlet 112, and a supplementary cooking steam input channel P11 extends between the supplementary cooking steam inlet 111 and the first supplementary cooking steam inlet 112. The first supplementary cooking steam inlet 112 is connected to one end of the transmission channel component 120, and the first supplementary cooking steam inlet 112 is generally oriented horizontally. The output end component 130 also has a second supplementary cooking steam inlet 132, and a supplementary cooking steam output channel P13 extends between the supplementary cooking steam outlet 131 and the second supplementary cooking steam inlet 132. The second supplementary cooking steam inlet 132 is connected to the other end of the transmission channel component 120, and the second supplementary cooking steam inlet 132 is generally oriented horizontally.

[0068] One end of the transmission channel component 120 is detachably inserted into, overlapped with, or directly connected to the steam generating end component 110 at the first supplementary steam interface 112. The other end of the transmission channel component 120 is detachably inserted into, overlapped with, or directly connected to the output end component 130 at the second supplementary steam interface 132. The detachable connection between the steam generating end component 110 / output end component 130 and the transmission channel component 120 can be a connection, such as the insertion shown in the illustration, in which case the sealing connection between the two is more stable and reliable; or it can be an abutment, in which case the steam generating end component 110 / output end component 130 has a deformation structure at the interface to seal against the transmission channel component 120, resulting in a better sealing effect. The illustration shows that both ends of the transmission channel component 120 are inserted into the steam generating end component 110 and the output end component 130 respectively via interfaces.

[0069] The transmission channel component 120 is a separate, self-removable part. Alternatively, the steam channel assembly 100 is integrally or fixedly connected to the removable cover assembly 12, and the transmission channel component 120 is integrally detachable from the removable cover assembly 12. In this case, the transmission channel component 120 is non-removably mounted on the removable cover assembly 12. The overall external shape of the transmission channel component 120 is a tubular member. Alternatively, the transmission channel component 120 can be any other elongated component with tubular connecting ends at both ends. The transmission channel component 120 can form a circumferentially sealed supplementary steam transmission channel P12, eliminating the need for additional sealing elements; the construction of the supplementary steam channel P1 is simple. The transmission channel component 120 extends along a reference straight line L. In other words, the transmission channel component 120 is a straight pipe, with its central axis on the reference straight line L, or its extension direction extending along the reference straight line L, thus making the supplementary steam transmission channel P12 a straight channel. The linear transmission channel component 120 shortens the flow distance and time of the supplementary steam, thereby quickly supplying supplementary steam to the food cooking chamber and reducing energy loss. Structurally, it can be easily manufactured and occupies less internal space in the cover 3, which is conducive to the miniaturization of the cover 3.

[0070] See Figure 5 The transmission channel member 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 member 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.

[0071] The output component 130 also has a cooking steam input channel P21 for the passage of cooking steam, through which cooking steam can be discharged to the external environment. The output component 130 also has a cooking steam inlet 133 and a cooking steam outlet 134, with the cooking steam input channel P21 extending between the cooking steam inlet 133 and the cooking steam outlet 134.

[0072] In the illustrated example, the supplementary cooking steam output channel P13 and the cooking steam input channel P21 are integrated into the output end component 130. This design allows the removable cover assembly 12 to have a steam channel centralized distribution section 12a. Specifically, the steam channel centralized distribution section 12a is provided with a supplementary cooking steam output channel P13 for supplying supplementary cooking steam and a cooking steam input channel P21 for supplying cooking steam. The supplementary cooking steam output channel P13 has a supplementary cooking steam outlet 131 communicating with the food cooking chamber; the cooking steam input channel P21 has a cooking steam inlet 133 communicating with the food cooking chamber. The supplementary cooking steam output channel P13 and the cooking steam input channel P21 are separated by a wall, and the supplementary cooking steam outlet 131 and the cooking steam inlet 133 are adjacent to or separated by a wall.

[0073] "Separated by a wall" means that they are separated by a wall. For example, the supplementary steam output channel P13 and the cooking steam input channel P21 are separated by a wall, with the supplementary steam output channel P13 formed on one side of the wall and the cooking steam input channel P21 formed on the other side of the wall.

[0074] This design cleverly integrates the supplementary steam output channel P13 and the cooking steam input channel P21 into a relatively small area, allowing the structure constituting these two steam channels to be set up more compactly, reducing the space occupied on the removable lid assembly 12. This results in a smaller internal space occupied by the lid 3, which is beneficial for the miniaturization of the lid 3 and improves the utilization rate of the internal space of the lid 3. In addition, it is beneficial for the steam channels to occupy a smaller cooking area on the removable lid assembly 12, and the spatial layout of the removable lid assembly 12 is reasonably adjusted.

[0075] The steam channel distribution section 12a can be located in the front region of the steam channel assembly 100. The steam channel distribution section 12a can also be located in the rear or central region of the cover plate 13. Placing the steam channel distribution section 12a in the rear region of the cover plate 13 further reduces the cooking area occupied by the steam channel assembly 100 on the cover plate 13. Placing the steam channel distribution section 12a in the central region of the cover plate 13 allows for more even distribution of steam into the food cooking chamber.

[0076] The supplementary steam output channel P13 is at least partially and substantially parallel to the cooking steam input channel P21. Optionally, the supplementary steam output channel P13 and the cooking steam input channel P21 are at least partially and substantially parallel in the vertical direction. The structure of the centralized steam channel distribution section 12a is more neat and compact, further reducing the space occupied on the removable cover. For the illustrated example, the supplementary steam output channel P13 and the cooking steam input channel P21 are at least partially and substantially parallel in the vertical direction on the output end member 130. Optionally, on the output end member 130, the vertical portion of the supplementary steam output channel P13 is substantially parallel to the vertical portion of the cooking steam input channel P21.

[0077] In some alternative embodiments not shown, the steam channel assembly includes at least two channel members, with the supplementary steam output channel P13 and the cooking steam input channel P21 integrated into a structure composed of at least two channel members. The combination of at least two channel members allows for the simultaneous formation of both the supplementary steam output channel P13 and the cooking steam input channel P21 in a localized area. Each channel member can be constructed and configured independently, making manufacturing easier and offering greater design flexibility. Optionally, the supplementary steam channel is located inside the cooking steam channel, and the supplementary steam channel and the cooking steam channel converge in the front region of the steam channel assembly, integrating the supplementary steam output channel P13 and the cooking steam input channel P21 into the front region of the steam channel assembly. This results in the supplementary steam outlet 131 and the cooking steam inlet 133 being adjacent to or adjacent to each other in the front region of the steam channel assembly. Exemplarily, a cooking steam channel is formed between the upper and lower channel members, and another channel member is provided within the area enclosed by the lower channel member, with the supplementary steam channel formed between the other channel member and the lower channel member.

[0078] The cooking steam exhaust channel P2 includes the cooking steam input channel P21. The cooking steam input channel P21 is independent of the supplementary cooking steam output channel P13. This configuration creates a dual-channel system within a single seal, delivering supplementary cooking steam and cooking steam respectively, serving two purposes. These two channels occupy the same area of ​​the cover 3, minimizing the internal space required and reducing the number of parts, thus facilitating the miniaturization of the cover 3 and improving its internal space utilization. Furthermore, the cooking steam input channel P21 has a higher temperature, and the adjacent supplementary cooking steam output channel P13 maintains an even higher temperature. This results in less heat loss when the steam entering the food cooking chamber passes through the supplementary cooking steam channel P1, leading to a higher temperature and better supplementary cooking effect. Additionally, it prevents the steam entering the food cooking chamber from condensing and liquefying during transmission in the supplementary cooking steam output channel P13, thus avoiding water droplets within the supplementary cooking steam from affecting the supplementary cooking effect.

[0079] Optionally, the transmission channel component 120 is injection molded from rigid plastic, such as PP (polypropylene), PE (polyethylene), PET (polyethylene terephthalate), PS (polystyrene), etc. If needed and / or desired, the transmission channel component 120 is made of soft plastic, such as silicone rubber. The steam generating end component 110 and the output end component 130 are both made of silicone rubber. The silicone rubber-made steam 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 results in a more stable and leak-proof sealing connection between the steam generating end component 110 and the transmission channel component 120, and between the output end component and the transmission channel component 120. Furthermore, given the complex structure of the steam generating end component 110 and the output end component 130, forced demolding can be achieved during silicone rubber injection molding, ensuring successful production of the finished product. Silicone rubber has the characteristics of long-term resistance to high temperature and moisture, no odor, low cost, reliable mass production process, good structural plasticity, and good long-term sealing performance.

[0080] See back Figure 1 and Figure 3 The cooking steam exhaust passage P2 also includes a cooking steam output passage P22. The cooking steam exhaust is connected to the food cooking chamber via the cooking steam input passage P21. Cooking steam can first enter the cooking steam input passage P21 and then be discharged to the external environment via the cooking steam output passage P22. The cover 3 also includes a steam valve 31 and a cooking steam passage component 32 forming the cooking steam output 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 liner 9. The cooking steam passage component 32 abuts against the output end component 130 to form a sealed connection. Passage seals 33 are provided between the steam valve 31 and the cooking steam passage component 32, and between the cooking steam passage component 32 and the liner 9, respectively, 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 channel component 32 and its detection end is located in the cooking steam output channel P22.

[0081] The following text combines Figure 7 , Figures 11 to 13 The structure of the steam generating end component 110 is described in detail.

[0082] The steam generating end component 110 includes a steam buffer chamber 114 and a lower deformable portion 115, with the lower deformable portion 115 connected to the bottom of the steam buffer chamber 114. The lower deformable portion 115 abuts against the steam generating device 40 / steam generating chamber, forming a gas-tight connection between them. The steam buffer chamber 114 is either butt-connected or plug-in connected to the transmission channel component 120, forming a gas-tight connection between them. The steam generating end component 110 serves as a seal at the junction with the steam generating device and at the junction with the transmission channel component 120, providing multiple functions, reducing the number of parts, simplifying the product structure, and improving space utilization.

[0083] A supplementary steam inlet 111 is formed at the lower deformed portion 115, specifically, the lower end of the lower deformed portion 115 forms the supplementary steam inlet 111. A first supplementary steam interface 112 is formed at the steam buffer chamber portion 114, which is used to connect or insert with the transmission channel component 120. Optionally, the steam generating end component 110 and the transmission channel component 120 can be detachably connected or inserted. In the disassembled state, the supplementary steam inlet 111 and the first supplementary steam interface 112 of the steam generating end component 110 can be disconnected, forming an open opening to facilitate cleaning of the internal channels of the steam generating end component 110.

[0084] When the cover 3 is closed, the lower deformable portion 115 can abut against the periphery of the upper opening, and during abutment, the lower deformable portion 115 undergoes elastic deformation. The steam buffer chamber 114 and the lower deformable portion 115 together form the supplementary cooking steam input channel P11. Optionally, the vertical dimension of the steam buffer chamber 114 is larger than the vertical dimension of the lower deformable portion 115, so that the supplementary cooking steam input channel P11 is mainly formed by the steam buffer chamber 114.

[0085] The steam generating end component 110 is snapped into the cover plate seat 14 with an interference fit. Specifically, the lower deformable portion 115 includes a sealing portion 115a connected to the steam buffer chamber portion 114. A first connecting groove 116 is provided between the steam buffer chamber portion 114 and the sealing portion 115a, and the first connecting groove 116 extends circumferentially along the steam generating end component 110 / sealing portion 115a. The opening of the first connecting groove 116 faces away from the interior of the steam buffer chamber portion 114. The edge of the cover plate seat mounting hole 20 is snapped into the first connecting groove 116 via the opening. The steam generating end component 110 can be movably and detachably installed to the cover plate seat 14 through the first connecting groove 116. The disassembly and assembly process is simple and easy to operate, facilitating the separate disassembly of the steam generating end component 110 for cleaning. The first connecting groove 116 can be annular in shape. If needed and / or desired, the number of first connecting grooves 116 can be more than two, and each first connecting groove 116 is arc-shaped.

[0086] The steam buffer chamber 114 is provided with an upper mounting portion 117 and a lower mounting portion 118 protruding from the outer peripheral surface of the steam buffer chamber 114. The lower mounting portion 118 is vertically spaced from the upper mounting portion 117, and a first connecting groove 116 is formed between them. The two protruding mounting portions have a certain elastic deformation capacity, which can deform when the steam generating end component 110 is disassembled, making the disassembly of the steam generating end component 110 easier. The upper mounting portion 117 is substantially parallel to the lower mounting portion 118, and the lower deformable portion 115 is connected to the outer peripheral end of the lower mounting portion 118 to connect with the steam buffer chamber 114 via the lower mounting portion 118. This further improves the structural strength of the lower deformable portion 115 and ensures reliable sealing.

[0087] The steam generating end component 110 also includes a first interface portion 113 for connection with the transmission channel component 120. The first interface portion 113 is connected to the steam buffer chamber portion 114 and communicates with the supplementary cooking steam input channel P11. The first interface portion 113 extends for a predetermined length along the direction of the central axis AX2 of the generating end outlet (in the illustrated example, it is along a generally horizontal direction), and the port of the first interface portion 113 constitutes a first supplementary cooking steam interface 112. The first interface portion 113 can receive a portion of the transmission channel component 120, thereby increasing the sealing area between the first interface portion 113 and the transmission channel component 120 and improving the sealing effect. Figure 13 As shown, one end of the transmission channel component 120 is inserted into the first interface portion 113 via the first supplementary steam interface 112, with the insertion depth reaching the supplementary steam input channel P11.

[0088] Optionally, such as Figure 11 As shown, both the first interface portion 113 and the upper mounting portion 117 protrude from the outer peripheral surface of the steam buffer chamber portion 114. The first interface portion 113 is connected to the upper mounting portion 117. The first interface portion 113 has better structural strength and can maintain an extension in a generally horizontal direction, which is beneficial for maintaining a stable seal with the transmission channel member 120. A reinforcing rib 101 is provided on the inner wall surface of the first supplementary steam interface 112, and the reinforcing rib 101 is arranged circumferentially along the first supplementary steam interface 112. For the illustrated example, as... Figure 12 As shown, a reinforcing rib 101 is provided on the inner wall surface of the first interface portion 113 at the first supplementary steam interface 112. The reinforcing rib 101 is arranged circumferentially along the first interface portion 113. The reinforcing rib 101 can be annular or dot-shaped and evenly distributed circumferentially along the first interface portion 113. By providing the reinforcing rib 101, the first interface portion 113 and the transmission channel member 120 are interference-fitted, resulting in a better sealing effect. Alternatively, a groove is provided between the first interface portion 113 and the upper mounting portion 117.

[0089] The steam generating end component 110 also includes a guide top wall 119. The guide top wall 119 is located at the top of the steam generating end component 110. The steam buffer chamber 114 has the guide top wall 119, and the guide top wall 119 is positioned opposite to the supplementary cooking steam inlet 111. The guide top wall 119 can block the upward flow of supplementary cooking steam, thereby changing the direction of supplementary cooking steam to the horizontal direction. Furthermore, the guide top wall 119 can block noise such as water boiling generated by the steam generating device 40 within the steam generating end component 110, preventing noise from spreading outward, thereby improving the noise reduction effect of the cooking appliance 1.

[0090] The steam buffer chamber 114 forms a steam buffer chamber, which is also the supplementary cooking steam input channel P11. The supplementary cooking steam gathers in the steam buffer chamber and then flows out from the first supplementary cooking steam interface 112. The steam buffer chamber helps to stabilize the pressure of the supplementary cooking steam, maintain the dynamic pressure balance of the supplementary cooking steam output from the steam generating end component 110, and thus stably deliver supplementary cooking steam to the food cooking chamber, ensuring the stability and consistency of the food moisturizing effect in the food cooking chamber. The inner cross-sectional area of ​​the steam buffer chamber 114, taken by a plane perpendicular to the central axis AX1 of the generating end inlet, is S. 腔 The cross-sectional area of ​​the first supplementary steam inlet 112, taken from a plane perpendicular to the central axis AX2 of the generator outlet, is S. 出口 The two satisfy the following condition: S 腔 >S 出口 Furthermore, the inner cross-sectional area of ​​the steam buffer chamber 114 is larger than the inner cross-sectional area of ​​the first interface 113. The flow velocity of the supplementary cooking steam through the steam buffer chamber 114 is less than the flow velocity through the first supplementary cooking steam interface 112, which effectively stabilizes the pressure of the supplementary cooking steam in the steam buffer chamber 114.

[0091] The steam buffer chamber 114 is provided with a first positioning portion 141, which is configured as a protrusion extending from the outer peripheral surface of the steam buffer chamber 114 or a recess extending from the outer peripheral surface of the steam buffer chamber 114. See also Figure 13 The cover plate seat 14 is provided with a positioning port 24. The first positioning part 141 is located inside the positioning port 24. The steam generating end component 110 is positioned by the first positioning part 141 to ensure that the first supplementary steam interface 112 faces the designated direction after the steam generating end component 110 is installed, so as to more accurately connect with the transmission channel component 120. Even after multiple disassemblies and reassemblies, accurate connection can be guaranteed. This can prevent the transmission channel component 120 from being subjected to bending stress due to large coaxiality deviation during assembly, and avoid irreversible deformation of the transmission channel component 120 due to the influence of high temperature environment, thereby ensuring the sealing effect at the first supplementary steam interface 112.

[0092] The first positioning part 141 is located within the first connecting slot 116. The positioning opening 24 is located at the edge of the cover plate seat mounting hole 20 and communicates with it. The positioning and engagement of the steam generating end component 110 are located in the same area, facilitating structural fit with similar components such as the cover plate seat 14 in the same area, simplifying assembly and manufacturing. The protrusion of the first positioning part 141 is smaller than the depth of the first connecting slot 116; more specifically, the vertical projection of the first positioning part 141 lies within the vertical projection of the first connecting slot 116. The first positioning part 141 does not protrude beyond the first connecting slot 116, and the first connecting slot 116 can also engage with the cover plate seat mounting hole 20 at the first positioning part 141.

[0093] The first positioning part 141 is located near the first supplementary steam inlet 112. Optionally, the first positioning part 141 is located vertically below the first supplementary steam inlet 112. The height of the first positioning part 141 is relatively low, which facilitates its proximity to the cover plate seat 14 for positioning and engagement. The first positioning part 141 and the first supplementary steam inlet 112 face the same direction, and the positioning and docking are on the same side of the steam generating end component 110, which facilitates quick assembly.

[0094] Optionally, the lower deformable portion 115 further includes a water storage portion 115b connected to the sealing portion 115a. In the assembled state / closed state, the sealing portion 115a abuts against the edge of the upper opening of the steam generating chamber. The water storage portion 115b extends from the lower end of the sealing portion 115a toward the central axis of the steam generating end member 110 and slopes upward, with the end of the water storage portion 115b forming a supplementary steam inlet 111. A water storage cavity 142 is formed between the water storage portion 115b and the sealing portion 115a. The steam generating end member 110 can be better sealed by the sealing portion 115a, and condensate can collect in the water storage cavity 142 formed by the water storage portion 115b and the sealing portion 115a, which facilitates the spillage of condensate when the steam generating end member 110 is disassembled, thus affecting the user experience. Alternatively, the steam generating end member 110 may not have a water storage portion 115b, and the end of the sealing portion 115a may form a supplementary steam inlet 111.

[0095] The steam generating end component 110 has the function of changing the flow direction of supplementary cooking steam. The supplementary cooking steam inlet 111 has a central axis AX1 at the inlet, and the first supplementary cooking steam interface 112 has a central axis AX2 at the outlet. There is a spatial or planar angle α between the central axes AX1 at the inlet and AX2 at the outlet. The central axis AX1 at the inlet and AX2 at the outlet are at opposite planes; if they are coplanar, they are at a planar angle α. The angle α can be 85°≤α≤95°. For example, suitable values ​​for α include 85°, 86°, 88°, 90°, 92°, 94°, and 95°. The central axes of the supplementary cooking steam inlet 111 and the first supplementary cooking steam interface 112 have an angle of 90° or close to 90°. This configuration allows the flow direction of the supplementary cooking steam to be reversed at a right angle or close to a right angle, for example, changing the flow direction of the supplementary cooking steam from a roughly vertical direction to a roughly horizontal direction. Thus, the steam generating end component 110 engages with the transmission channel component 120 in a generally horizontal direction. Compared to a vertical engagement, the horizontal engagement saves structural space in the vertical direction, which helps to reduce the vertical dimensions of the steam channel assembly and thus lower the height of the cooking appliance 1. Furthermore, with the horizontal engagement, the steam generating end component 110 is not significantly obstructed by the transmission channel component 120 in the vertical direction, making it easier to assemble and disassemble the steam generating end component 110 independently. The engagement position is closer to the food cooking chamber, resulting in a more compact overall structure of the steam generating device 40.

[0096] The following text combines Figure 8 , Figure 9 , Figure 14 and Figure 15 The structure of the transmission channel component 120 is described in detail.

[0097] like Figure 14 As shown, the transmission channel component 120 includes a hollow channel component body 122, a channel steam inlet 123, and a channel steam outlet 124. The channel steam inlet 123 is connected to one end of the channel component body 122, and the channel steam outlet 124 is connected to the other end of the channel component body 122 opposite to that end. The channel steam inlet 123 can be detachably inserted into, overlapped with, or connected to one end of the first supplementary steam interface 112 / output component 130, and the channel steam outlet 124 can be detachably inserted into, overlapped with, or connected to one end of the second supplementary steam interface 132 / output component 130. The channel steam inlet 123 extends along a first direction, and the channel steam outlet 124 extends along a first direction, wherein the first direction is a horizontal direction or the angle between the first direction and the horizontal direction is less than or equal to 5°. This facilitates the connection of the transmission channel component 120 with the steam generating end component 110 and the output end component 130 in a generally horizontal direction, respectively.

[0098] 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 the outer circumferential surface of the inserted end and the inner circumferential surface of the port form a seal; "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 a seal is formed at the two end faces.

[0099] The steam inlet 123 and steam outlet 124 of the transmission channel form a tubular section, the outer cross-sectional dimension of which is smaller than that of the main body 122 of the transmission channel component. This facilitates the insertion and separation of these two mating ends with their corresponding end seals, making the assembly and disassembly of the transmission channel component 120 easier. In the illustrated example, the cross-sectional shape of the transmission channel component 120 is circular, thus the outer diameter of the tubular section is smaller than the outer diameter of the main body 122 of the transmission channel component.

[0100] Optionally, the transmission channel component 120 is made of a rigid material, which may include plastic materials such as PP (polypropylene), PE (polyethylene), PET (polyethylene terephthalate), PS (polystyrene), etc. If required and / or desired, the transmission channel component 120 is made of a flexible material, such as silicone rubber.

[0101] Channel connectors 121 are connected to both sides of the transmission channel member 120 at its central portion. Channel connectors 121 are supported on the top of the support member 23 to stably hold the transmission channel member 120 on the cover plate seat 14. The shape of the channel connectors 121 corresponds to the shape of the outer peripheral contour of the support member 23. Exemplarily, the support member 23 includes a main body composed of ribs forming a quadrilateral shape. The channel connectors 121 are supported on the top surface of the ribs, and their shape corresponds to the quadrilateral shape.

[0102] Optionally, the channel connector 121 is provided with a fastening hole 129, which is located on the first side of the transmission channel member 120 at the middle. For example... Figure 8 As shown, the support member 23 is provided with a fastening post 25, and the removable cover assembly 12 includes fasteners that pass through the fastening holes 129 and are locked to the fastening post 25. The transmission channel member 120 is fixed in a non-movable and detachable manner, so that it does not need to be disassembled frequently. When cleaning is required, it can be rinsed together with the removable cover assembly 12. The transmission channel member 120 is fastened to the cover plate 13 and / or cover plate seat 14 by fasteners, which is an optional design; if needed and / or desired, other detachable fixing methods can be used to connect the transmission channel member 120 to the cover plate 13 and / or cover plate seat 14.

[0103] The channel connector 121 is provided with a latching part 143, which is located on the second side of the transmission channel member 120 at the middle. For example... Figure 9 As shown, the support member 23 has a groove 26, the opening of which faces horizontally. In the assembled state, the snap-fit ​​part 143 can snap into the groove 26. The transmission channel member 120 is fixed by a snap-fit, movable, and detachable structure, which improves assembly efficiency. During installation, the snap-fit ​​part 143 can be snapped into the groove 26 first, and then the fastener can be passed through the fastening hole 129 and locked to the fastening post 25.

[0104] The support member 23 is also provided with a channel limiting opening 27. The channel limiting opening 27 is a notch provided on the upper side of the support member 23, and its shape is adapted to the shape of the transmission channel member. The central axis of the channel limiting opening 27 is approximately parallel to the extension direction of the transmission channel member 120. The transmission channel member 120 is partially limited by the channel limiting opening 27. The transmission channel member 120 can be positioned to the support member 23 through the channel limiting opening 27, which facilitates rapid assembly and restricts its horizontal movement after assembly, so that it is stably and reliably fixed on the cover plate seat 14. For example, the outer peripheral contour of the transmission channel member 120 is cylindrical, and the inner peripheral contour of the channel limiting opening 27 is a partially circular shape.

[0105] The following text combines Figure 7 and Figure 16 The structure of the output component 130 is described in detail.

[0106] like Figure 16 As shown, the output component 130 has the function of changing the direction of the supplementary cooking steam flow. The second supplementary cooking steam interface 132 faces horizontally and is opposite to the first supplementary cooking steam interface 112. There is a spatial or planar angle α between the central axis AX3 of the supplementary cooking steam outlet 131 and the central axis AX4 of the second supplementary cooking steam interface 132. The angle α can be 85°≤α≤95°. For example, the angle α can be 85°, 86°, 88°, 90°, 92°, 94°, 95°, etc. The central axes of the supplementary cooking steam outlet 131 and the second supplementary cooking steam interface 132 have an angle of 90° or close to 90°. This arrangement allows the direction of the supplementary cooking steam flow to be changed from a generally horizontal direction to a generally vertical direction. Thus, the output component 130 engages with the transmission channel component 120 in a generally horizontal direction. Furthermore, due to the horizontal connection method, the output terminal component 130 is not significantly obstructed by the transmission channel component 120 when it is disassembled or assembled in the vertical direction, making it more convenient to disassemble or assemble the output terminal component 130 separately.

[0107] Optionally, the central axis of the second supplementary steam inlet 132 is approximately collinear with the central axis of the first supplementary steam inlet 112. This prevents the transmission channel component 120 from being subjected to bending stress due to large coaxiality deviations during assembly, avoids irreversible deformation of the transmission channel component 120 due to high-temperature environments, and thus ensures a sealing effect at the two supplementary steam inlets. The supplementary steam output channel P13 and / or the cooking steam input channel P21 extend at least partially in the vertical direction. The output end component 130 has a certain dimension in the vertical direction to facilitate docking with adjacent components; the vertical channel formed by the output end component 130 can transport supplementary steam and / or cooking steam in the vertical direction.

[0108] The output component 130 includes a hollow cylindrical body 136 and a partition wall 137 located inside the cylindrical body 136. The internal space of the cylindrical body 136 is divided by the partition wall 137 into a supplementary steam output channel P13 and a cooking steam input channel P21. Specifically, the partition wall 137 and the portion of the cylindrical body 136 adjacent to the second supplementary steam interface 132 form the supplementary steam output channel P13. The partition wall 137 and another portion of the cylindrical body 136 form the cooking steam input channel P21. The partition wall 137 includes a first partition extending in a generally vertical direction and a second partition extending in a generally horizontal direction. The second partition is located above the first partition to block the supplementary steam output channel P13. The cooking steam input channel P21 and the supplementary steam output channel P13 are generally parallel at the vertical portion of the partition wall 137.

[0109] The bottom of the output end component 130 is engaged with the cover plate 13 with an interference fit. The output end component 130 is also detachably mounted to the cover plate 13 via a slot. Specifically, the bottom of the columnar body 136 is provided with a second connecting slot 138 for mounting the output end component 130. The second connecting slot 138 extends circumferentially along the output end component 130, and the opening of the second connecting slot 138 faces away from the interior of the columnar body 136. The second connecting slot 138 is annular in shape. The edge of the cover plate mounting hole 21 is engaged with the second connecting slot 138 via the slot. Specifically, the bottom of the columnar body 136 is provided with a second connecting slot 138 for mounting the output end component 130. The second connecting slot 138 extends circumferentially along the output end component 130, and the opening of the second connecting slot 138 faces away from the interior of the columnar body 136. The output component 130 can be detachably installed onto the cover plate 13 via the second connecting slot 138. The disassembly and assembly process is simple and easy to operate, and it is convenient to disassemble the output component 130 separately for cleaning.

[0110] The columnar body 136 is provided with a fixing part 139 protruding from the outer peripheral surface of the columnar body 136, and the fixing part 139 forms a second connecting groove 138. The portion of the fixing part 139 used to form the second connecting groove 138 has a certain elastic deformation capability, which can deform when the output end component 130 is disassembled or assembled, making it easier to disassemble the output end component 130.

[0111] The output end component 130 also includes a second interface portion 135 for connection with the transmission channel component 120. The second interface portion 135 is located on the columnar body 136 and communicates with the supplementary steam output channel P13. The second interface portion 135 extends horizontally for a predetermined length, and its port forms a second supplementary steam interface 132. The second interface portion 135 can receive a portion of the transmission channel component 120, thereby increasing the sealing area between the second interface portion 135 and the transmission channel component 120 and improving the sealing effect. Figure 7 As shown, the other end of the transmission channel component 120 is inserted into the second interface portion 135 via the second supplementary steam interface 132, with the insertion depth reaching the supplementary steam input channel P11. A reinforcing rib 101 is provided on the inner wall surface of the second supplementary steam interface 132, and the reinforcing rib 101 is arranged circumferentially along the second supplementary steam interface 132. In the illustrated example, a reinforcing rib 101 is provided on the inner wall surface of the second interface portion 135 at the second supplementary steam interface 132. The reinforcing rib 101 is arranged circumferentially along the second interface portion 135.

[0112] Optionally, the cross-sectional shape of the supplementary steam output channel P13 is circular. In the direction perpendicular to the central axis of the output end member 130, the cross-sectional shape of the cooking steam input channel P21 is crescent-shaped, thus the shape of the cooking steam inlet 133 is crescent-shaped. The shape of the cooking steam outlet 134 is circular.

[0113] like Figure 16 and Figure 17 As shown, the output end component 130 also includes an upper deformable portion 144, which is disposed on the top of the output end component 130. The upper deformable portion 144 forms part of the cooking steam input channel P21, and the upper end of the upper deformable portion 144 surrounds the upward-facing cooking steam outlet 134. The upper deformable portion 144 can correspond to the cooking steam channel component 32 to form a sealed connection. Specifically, the liner 9 is provided with a liner steam outlet 29, and the upper deformable portion 144 abuts against the edge of the liner steam outlet 29. When abutting, the lower deformable portion 115 undergoes elastic deformation. The cooking steam channel component 32 communicates with the cooking steam input channel P21 via the liner steam outlet 29. The upper deformable portion 144 can be connected to the top of the columnar body 136.

[0114] See back Figure 1 and Figure 7The cover body 8 has an inner wall surface 8a. The inner wall surface 8a faces the steam channel assembly 100. When the detachable cover assembly 12 is assembled into the cover body 3, the upper side of the guide top wall 119 of the steam generating end member 110 is adjacent to or abuts the inner wall surface 8a, and the upper side of the transmission channel member 120 is adjacent to or abuts the inner wall surface 8a. The steam channel assembly 100 is compactly arranged with the cover body 8 in the cover body, and the internal space of the cover body 3 can be fully utilized. This helps to reduce the thickness of the cover body 3, reduce the overall height of the product, and miniaturize the product.

[0115] Optionally, the upper surface of the transmission channel component 120 is substantially flush, or in other words, the upper surface of the transmission channel component 120 lies on a curved surface / plane. For the illustrated example, the upper surface of the transmission channel component 120 is an upward-facing curved surface. The upper surface of the guide wall 119 is substantially flush, or in other words, the upper surface of the guide wall 119 lies on a curved surface / plane. For the illustrated example, the upper surface of the guide wall 119 is an upward-facing plane. The highest points of the upper surfaces of the transmission channel component 120 and the guide wall 119 are approximately on the same plane F. Figure 1 and Figure 7 The approximate location of plane F is schematically shown using dashed lines.

[0116] It should be noted that due to manufacturing and assembly reasons, the orientation and position of components may deviate. The terms "approximately" and "basically" used to describe the orientation and position of components above refer to a fluctuation of approximately ±5° relative to a specified direction and position. Indicatively, "approximately horizontal direction" means an angle within ±5° of the horizontal direction. The various seals and sealing rings mentioned above, such as channel seal 33, pot mouth seal 7, and through-hole seal 22, are made of soft, elastic materials, such as soft rubber, which can be silicone rubber. Components used to form the supplementary steam passage P1 and the cooking steam exhaust passage P2 are made of food-grade materials.
