Description

Technical Field

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

[0002] Existing steam cooking appliances, such as steam rice cookers, generally have a steam inlet channel inside the lid, which transports high-temperature steam from the steam source to the cooking chamber. 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 can be used to heat the food inside the cooking chamber and moisten it.

[0003] However, the existing steam inlet channel is formed by connecting an upper channel cover and a lower channel cover. To prevent air leakage, sealing rings are required at the connection points between the upper and lower channel covers, the connection point between the upper channel cover and the water container, and the connection point between the upper channel cover and the inner cover, resulting in a large number of parts inside the cover body.

[0004] Therefore, a steam-generating end component 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.

[0006] To at least partially solve the above problems, this application provides a steam generating end component for a cooking appliance, the cooking appliance including a steam generating device and a main component for supplementary steam passage. The steam generating end component is an integral hollow part, and includes a lower deformable part and a steam buffer cavity connected to the lower deformable part; The lower deformable part is used to abut against the steam generator and form a gas-sealed docking state between the two; The steam buffer chamber is used to connect or plug into the main component of the supplementary steam channel, forming a gas-sealed connection between the two.

[0007] According to this design, the hollow steam generating end component can independently form a channel for supplementary cooking steam. The steam generating end component also serves as a seal at the junction with the steam generating device and at the junction with the main component of the supplementary cooking steam channel. This multi-functional design reduces the number of parts, simplifies the product structure, and improves space utilization. The supplementary cooking steam gathers within the steam buffer chamber formed by the steam generating end component and then flows out from the steam outlet at the generating end. The steam buffer chamber helps stabilize the pressure of the supplementary cooking steam, maintaining the dynamic pressure balance of the supplementary cooking steam output from the steam generating end component. This ensures a stable supply of supplementary cooking steam to the food cooking chamber, guaranteeing the stability and consistency of the food's moisture retention effect within the cooking chamber.

[0008] Optionally, the lower deformed portion is provided with a generating end steam inlet, which is used to connect with the steam generating device, and the generating end steam inlet has a generating end inlet central axis AX1; The steam buffer chamber is provided with a generating end steam outlet, which is used to be connected to or inserted into the main component of the supplementary cooking steam channel. The generating end steam outlet has a generating end outlet central axis AX2 and extends horizontally. Wherein, there is a spatial or planar angle α between the central axis AX1 of the generator inlet and the central axis AX2 of the generator outlet, wherein the angle α is: 85°≤α≤95°.

[0009] According to this solution, the steam generating end component has the function of changing the direction of the supplementary cooking steam flow. It can reverse the flow of the supplementary cooking steam at a right angle or near a right angle, for example, changing the flow of the supplementary cooking steam from a roughly vertical direction to a roughly horizontal direction. Thus, the steam generating end component connects to the main component of the supplementary cooking steam channel in a roughly horizontal direction. Compared to a vertical connection, a horizontal connection saves structural space in the vertical direction, which helps to reduce the vertical dimensions of the steam channel assembly and consequently lowers the height of the cooking appliance.

[0010] Furthermore, by using a horizontal connection method, the steam generating end component can be disassembled and assembled in the vertical direction without being obstructed by the main component of the steam channel, making it easier to disassemble and assemble the steam generating end component separately; the connection position is closer to the food cooking chamber, making the overall structure of the steam generating device more compact.

[0011] Optionally, the steam buffer chamber has a guide wall positioned opposite the steam inlet at the generating end. According to this design, the guide wall guides the supplementary steam to flow horizontally, allowing the steam flow to enter the steam channel more smoothly, thus reversing the direction of the supplementary steam towards the horizontal. Furthermore, the guide wall can block noise generated by the steam generator, such as water boiling, within the steam generating end component, reducing noise dissipation outside the channel during steam generation, thereby improving the noise reduction effect of the cooking appliance.

[0012] Optionally, the steam inlet at the generating end is located at the bottom end of the steam generating end component and faces the steam generating device. According to this solution, the steam generating end component is suitable for cooking appliances where the steam generating device is located in the pot body, and can be connected to the steam generating device located in the pot body.

[0013] Optionally, the inner cross-sectional area of ​​the steam buffer chamber, taken by a plane perpendicular to the central axis AX1 of the generator inlet, is S. 腔 The cross-sectional area of ​​the steam outlet at the generating end, taken by a plane perpendicular to the central axis AX2 of the generating end outlet, is S. 出口 The two satisfy the following condition: S 腔 >S 出口 According to this scheme, the flow velocity of the supplementary cooking steam through the steam buffer chamber is less than the flow velocity through the steam outlet at the generating end, which effectively stabilizes the pressure of the supplementary cooking steam in the steam buffer chamber.

[0014] Optionally, the lower deformable portion includes a sealing portion connected to the steam buffer chamber, the steam buffer chamber being cylindrical, and a groove being provided between the steam buffer chamber and the sealing portion. According to this solution, the steam generating end component can be detachably mounted to a supporting component such as a cover plate seat via the groove. The assembly and disassembly process is simple and easy to operate, facilitating the separate removal of the steam generating end component for cleaning.

[0015] Optionally, the slot extends circumferentially along the sealing portion. According to this design, the slot's circumferential extension length is designed to be relatively large, resulting in more stable and reliable fixation of the steam generating end component on the supporting component.

[0016] Optionally, the slot is provided with a first positioning part near the steam outlet of the generating end. According to this solution, the steam generating end component is positioned by the first positioning part to ensure that the steam outlet of the generating end faces the designated direction after the steam generating end component is installed, so as to more accurately connect with the main component of the supplementary steam channel. Even after multiple disassemblies and reassemblies, accurate connection can be guaranteed. This can prevent the main component of the supplementary steam channel from being subjected to bending stress due to large coaxiality deviations during assembly, and avoid irreversible deformation of the main component of the supplementary steam channel due to the influence of high temperature environment, thereby ensuring the sealing effect at the steam outlet of the generating end.

[0017] Optionally, the first positioning part is located vertically below the steam outlet of the generating end. According to this solution, the height of the first positioning part is relatively low, which facilitates its proximity to a load-bearing component such as a cover plate seat for positioning and engagement. The first positioning part faces the same direction as the steam outlet of the generating end, and the positioning and docking are on the same side of the steam generating end component, which facilitates rapid assembly.

[0018] Optionally, the steam generating end component includes a first interface portion for connecting to the main component of the supplementary cooking steam channel. The first interface portion is connected to the steam buffer chamber and extends for a predetermined length along the central axis AX2 of the generating end outlet. The port of the first interface portion constitutes the steam outlet of the generating end. According to this solution, the first interface portion can receive a portion of the main component of the supplementary cooking steam channel, thereby increasing the sealing area between the interface portion and the main component of the supplementary cooking steam channel and improving the sealing effect.

[0019] Optionally, the inner wall surface of the first interface portion is provided with reinforcing ribs, which are arranged circumferentially along the first interface portion. According to this solution, the interface portion and the main component of the supplementary steam channel are press-fitted, resulting in a better sealing effect.

[0020] Optionally, the steam buffer chamber is cylindrical and has an upper mounting portion. Both the first interface portion and the upper mounting portion protrude from the outer peripheral surface of the steam buffer chamber. The first interface portion is connected to the upper mounting portion, or a groove is provided between them. According to this solution, the connection between the first interface portion and the upper mounting portion improves the structural strength of the steam generating end component, enhances its support capacity, and stably supports the main component of the supplementary steam channel, which is beneficial for maintaining a stable seal with the main component of the supplementary steam channel. The groove between the first interface portion and the upper mounting portion reduces the material required for the steam generating end component, thus lowering costs.

[0021] Optionally, the steam generating device includes a steam generating chamber with an upper opening; the lower deformable part includes a sealing part and a water storage part, and in the assembled state, the sealing part abuts against the edge of the upper opening. According to this solution, the steam generating end component can be better sealed by the sealing part, and condensate can be collected in the water storage chamber formed by the water storage part and the sealing part, which facilitates the spillage of condensate when disassembling the steam generating end component, thus improving the user experience.

[0022] Optionally, the steam generating end component is made of an elastic material; and / or, the steam generating end component is made of silicone rubber. According to this solution, the steam generating end component made of an elastic material has a certain elastic deformation capacity, resulting in better and more durable sealing at the joint between the steam generating end component and the main body component of the supplementary steam channel. The steam generating end component made of silicone rubber, in addition to its sealing ability, primarily possesses structural strength and support capacity, enabling it to stably support the main body component of the supplementary steam channel at the joint, thus improving the stability of the sealed connection between the steam generating end component and the main body component of the supplementary steam channel and preventing air leakage. Furthermore, given the complex structure of the steam generating end component, forced demolding can be achieved during injection molding with silicone rubber, ensuring successful production of the finished product.

[0023] According to another aspect of this application, a steam channel assembly is provided for a cooking appliance, the cooking appliance including a food cooking chamber and a steam generating device.

[0025] Optionally, the main component of the supplementary steam channel is a separately detachable part. According to this solution, the main component of the supplementary steam channel can be disassembled independently, facilitating separate cleaning of its internal channels and making cleaning more convenient. Alternatively, the steam channel assembly is integrally or fixedly connected to the removable cover assembly, and the main component of the supplementary steam channel is integrally detachable with the removable cover assembly. According to this solution, the main component of the supplementary steam channel can be disassembled and cleaned together with the removable cover assembly.

[0026] Optionally, the steam channel assembly further includes an output end component, one end of which is detachably inserted into, overlapped with, or opposite to the main body component of the supplementary steam channel, and the other end of which is used to communicate with the food cooking chamber. According to this solution, in the disassembled state, the supplementary steam inlet of the output end component can be disconnected, forming an open opening, and the supplementary steam outlet is also an open opening, to facilitate cleaning of the internal channels of the output end component.

[0028] According to this design, a single component forms a dual-channel system, delivering supplementary steam and cooking steam respectively. This dual-purpose design allows both channels to occupy the same area of ​​the lid, minimizing internal space requirements and reducing the number of parts, thus promoting lid miniaturization and improving space utilization. Furthermore, the cooking steam exhaust channel maintains a higher temperature, while the adjacent supplementary steam exhaust channel retains an even higher temperature. This minimizes heat loss as the supplementary steam enters the cooking chamber, resulting in higher steam temperatures and better supplementary cooking. Additionally, it prevents condensation during transmission through the supplementary steam exhaust channel, avoiding water droplets that could negatively impact the supplementary cooking effect. This design reduces heat loss during steam transmission, effectively ensuring optimal moisture retention for foods such as rice.

[0029] Optionally, the central axis of the steam inlet at the output end and the central axis of the steam outlet at the generating end are substantially collinear. According to this design, it is possible to prevent the main component of the steam supply channel from being subjected to bending stress due to large coaxiality deviations during assembly, and to avoid irreversible deformation of the main component of the steam supply channel due to high-temperature environments, thereby ensuring the sealing effect at the two steam supply interfaces.

[0032] Optionally, the output end component is made of an elastic material; and / or, the output end component is made of silicone rubber. According to this solution, the output end component made of an elastic material has a certain elastic deformation capacity, resulting in better and more durable sealing at the junction of the output end component with the food cooking cavity and the main body of the supplementary steam channel. The output end component made of silicone rubber, in addition to its sealing ability, primarily possesses structural strength and support capacity, enabling it to stably support the main body of the supplementary steam channel at the junction, thus improving the stability of the sealed connection between the output end component and the main body of the supplementary steam channel and preventing air leakage.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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 cavity. In order to deliver the supplementary cooking steam to the food cooking cavity, the cover 3 is provided with a supplementary cooking steam supply channel P1 that communicates with the food cooking cavity. The supplementary cooking steam supply channel P1 is used for the passage of steam for supplementary cooking in 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.

[0059] 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 typically 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 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 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] The following text combines Figures 1 to 15 The specific structure of the steam supply channel P1 for supplementary cooking is described.

[0064] like Figures 1 to 4 As shown, the lid 3 also includes a steam channel assembly 100 for forming a supplementary steam supply 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 supply channel P1 on the steam channel assembly 100. The lid through-hole 19 occupies at least the central area of ​​the removable lid assembly 12. The steam channel assembly 100 is positioned adjacent to 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.

[0065] 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.

[0066] 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 for supplementary cooking steam passage, a supplementary cooking steam passage main body component 120, and an output end component 130. The supplementary cooking steam passage main body 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 supplementary cooking steam passage main body component 120 is sealed and connected to both the steam generating end component 110 and the output end component 130.

[0067] Specifically, such as Figure 6As shown, the steam generating end member 110 has a steam generating end inlet 111 for docking with the steam generating device 40. The steam generating end inlet 111 faces vertically. In the illustrated example, the steam generating end inlet 111 is located at the bottom end of the steam generating end member 110 and is positioned towards 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 steam generating end 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 an output end supplementary cooking steam outlet 131 for communicating with the food cooking chamber. The output end supplementary cooking steam outlet 131 faces downwards to spray supplementary cooking steam downwards towards the food cooking chamber.

[0068] The steam passage assembly 100 is detachably mounted across the cover plate 13 and the cover plate seat 14. The steam generating end component 110 is connected to the cover plate seat 14, the output end component 130 is connected to the cover plate 13, and the main steam passage component 120 is detachably mounted across both the cover plate 13 and the cover plate seat 14. The steam generating device 40 is located at the rear corner of the pot body 2, and the 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, so that the generating end steam inlet 111 is located at the 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, and steam enters the generating end steam inlet 111 from bottom to top, making the steam path between the generating end steam inlet 111 and the water container 41 shorter and more direct. The steam generating end component 110 abuts against the periphery of the upper opening when the cover body 3 is closed on 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.

[0069] 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.

[0070] like Figure 7 and Figure 10As shown, the supplementary cooking steam supply channel P1 extends between the steam inlet 111 at the generating end and the supplementary cooking steam outlet 131 at the output end. Specifically, the steam generating end component 110 is a single hollow piece, for example, a single hollow piece made of an elastic material. The main component 120 of the supplementary cooking steam channel is a component with a circular tubular channel. The output end component 130 is a single hollow piece, for example, a single hollow piece made of an elastic material. The steam generating end component 110 forms a steam buffer chamber P11 with the steam inlet 111 at the generating end, the main component 120 of the supplementary cooking steam channel forms a supplementary cooking steam transmission section channel P12, and the output end component 130 forms a supplementary cooking steam output section channel P13 with the supplementary cooking steam outlet 131 at the output end. The supplementary cooking steam output section channel P13 is connected to the steam buffer chamber P11 through the supplementary cooking steam transmission section channel P12. The supplementary cooking steam enters the steam buffer chamber P11 from the steam inlet 111 at the generating end, 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 supplementary cooking steam outlet 131 at the output end.

[0071] 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 steam buffer chamber P11. The supplementary cooking steam passage main body component 120 is detachably connected to the cover plate seat 14. The supplementary cooking steam passage main body 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 supplementary cooking steam passage main body 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 section passage P13.

[0072] like Figure 8 and Figure 10 As shown, the cover plate seat 14 is provided with a cover plate seat mounting hole 20. The steam generating end component 110 of the steam channel assembly 100 is detachably inserted into the cover plate seat mounting hole 20, for example, the steam generating end component 110 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 seat 14 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 is provided with 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.

[0073] 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. 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.

[0074] 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 main body component 120 of the supplementary steam passage is provided with a passage connector 121. The passage connector 121 is integrally provided with the main body component 120 of the supplementary steam passage, for example, connected to its approximately central portion. The passage connector 121 can be detachably connected to the support member 23, thereby detachably providing the main body component 120 of the supplementary steam passage. For example, the passage connector 121 is connected to the support member 23 by fasteners such as screws and / or clips, so that the main body component 120 of the supplementary steam passage is non-removably detachable / movably detachable.

[0075] Optionally, the support member 23 is integrally formed on the cover plate seat 14; the channel connector 121 is integrally formed on the main body member 120 of the supplementary steam channel. 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 main body member 120 of the supplementary steam channel by welding, fasteners such as screws, snap-fit, plug-in, or other suitable means.

[0076] The steam generating end component 110 has a steam generating end outlet 112, and a steam buffer chamber P11 extends between the steam generating end inlet 111 and the steam generating end outlet 112. The steam generating end outlet 112 is connected to or inserted into one end of the main component 120 of the supplementary cooking steam passage, and the steam generating end outlet 112 is generally oriented horizontally. The output end component 130 also has an output end supplementary cooking steam inlet 132, and a supplementary cooking steam output section passage P13 extends between the output end supplementary cooking steam outlet 131 and the output end supplementary cooking steam inlet 132. The output end supplementary cooking steam inlet 132 is connected to or inserted into the other end of the main component 120 of the supplementary cooking steam passage, and the output end supplementary cooking steam inlet 132 is generally oriented horizontally.

[0077] One end of the main component 120 of the supplementary steam passage is detachably inserted into, overlapped with, or directly connected to the steam generating end component 110 at the steam outlet 112. The other end of the main component 120 of the supplementary steam passage is detachably inserted into, overlapped with, or directly connected to the output end component 130 at the supplementary steam inlet 132. The detachable connection between the steam generating end component 110 / output end component 130 and the main component 120 of the supplementary steam passage 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 main component 120 of the supplementary steam passage, resulting in a better sealing effect. The illustration shows that both ends of the main component 120 of the supplementary steam passage are inserted into the steam generating end component 110 and the output end component 130 respectively via interfaces.

[0078] The main component 120 of the supplementary cooking steam passage is a separate, self-removable part. Alternatively, the steam passage assembly 100 is integrally or fixedly connected to the removable cover assembly 12, and the main component 120 of the supplementary cooking steam passage is integrally detachable from the removable cover assembly 12. In this case, the main component 120 of the supplementary cooking steam passage is non-removably mounted on the removable cover assembly 12. The overall external shape of the main component 120 of the supplementary cooking steam passage is tubular. Alternatively, the main component 120 of the supplementary cooking steam passage can be any other elongated component with tubular connecting ends at both ends. The main component 120 of the supplementary cooking steam passage can form a circumferentially sealed supplementary cooking steam transmission section passage P12, eliminating the need for additional sealing components; the construction of the supplementary cooking steam supply passage P1 is simple. The main component 120 of the supplementary cooking steam passage extends along a reference straight line L. In other words, the main component 120 of the supplementary cooking steam passage 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 cooking steam transmission section passage P12 a straight passage. The straight-line steam channel main component 120 shortens the flow distance and time of the steam, thereby quickly supplying 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.

[0079] See Figure 5 The main component 120 of the supplementary steam passage 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 main component 120 of the supplementary steam passage 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.

[0080] The output end component 130 also forms a cooking steam exhaust channel P21 for the passage of cooking steam, through which cooking steam can be discharged to the external environment. The output end component 130 also forms an output end cooking steam inlet 133 and an output end cooking steam outlet 134, with the cooking steam exhaust channel P21 extending between the output end cooking steam inlet 133 and the output end cooking steam outlet 134. The cooking steam exhaust channel P2 includes this cooking steam exhaust channel P21. The cooking steam exhaust channel P21 is independent of the supplementary cooking steam output section channel P13. With this configuration, a single seal forms a dual-channel system, respectively delivering supplementary cooking steam and cooking steam, serving two purposes. Furthermore, these two channels can occupy the same area of ​​the cover 3, resulting in a small internal space occupation and fewer parts, which is beneficial for the miniaturization of the cover 3 and improves the utilization rate of the internal space of the cover 3. Furthermore, the cooking steam exhaust channel P21 has a high temperature, and the adjacent supplementary cooking steam output channel P13 can maintain an even higher temperature. On the one hand, the steam entering the food cooking chamber loses less heat when passing through the supplementary cooking steam supply channel P1, resulting in a higher temperature for the supplementary cooking steam and a better supplementary cooking effect. On the other hand, 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 in the supplementary cooking steam from affecting the supplementary cooking effect. The output end component 130 serves as a seal at both the output end cooking steam inlet 133 and the output end supplementary cooking steam outlet 131. This multi-functional design reduces heat loss during the transmission of supplementary cooking steam, effectively ensuring optimal moisture retention for foods such as rice.

[0081] Optionally, the main component 120 of the supplementary steam channel is injection molded from rigid plastic, such as PP (polypropylene), PE (polyethylene), PET (polyethylene terephthalate), PS (polystyrene), etc. If needed and / or desired, the main component 120 of the supplementary steam channel 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 supplementary steam channel main component 120 at the joints. This results in a more stable sealing connection between the steam generating end component 110 and the supplementary steam channel main component 120, and between the output end component and the supplementary steam channel main component 120, preventing air leakage. Furthermore, the complex structure of the steam generating end component 110 and the output end component 130 allows for forced demolding 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.

[0082] See back Figure 1 and Figure 3 The cooking steam exhaust passage P2 also includes a cooking steam discharge passage P22. The cooking steam discharge is connected to the food cooking chamber via the cooking steam exhaust passage P21. Cooking steam first enters the cooking steam exhaust 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 liner 9. The cooking steam passage component 32 abuts against the output end component 130 to form a sealed connection. Channel 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 passage component 32 and its detection end is located in the cooking steam exhaust passage P22.

[0083] The following text combines Figure 7 , Figures 11 to 13 The structure of the steam generating end component 110 is described in detail.

[0084] 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, forming a gas-tight connection between them. The steam buffer chamber 114 is either butt-connected or plug-in connected to the main component 120 of the supplementary steam channel, 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 main component 120 of the supplementary steam channel, providing multiple functions, reducing the number of parts, simplifying the product structure, and improving space utilization.

[0085] A steam inlet 111 is formed at the lower deformed portion 115, specifically, the lower end of the lower deformed portion 115 forms the steam inlet 111. A steam outlet 112 is formed at the steam buffer chamber portion 114, and the steam outlet 112 is used to connect or insert with the main body component 120 of the supplementary cooking steam channel. Optionally, the steam generating end component 110 and the main body component 120 of the supplementary cooking steam channel can be detachably connected or inserted. In the disassembled state, the steam inlet 111 and the steam outlet 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.

[0086] 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 portion 114 forms the steam buffer chamber P11. Optionally, the vertical dimension of the steam buffer chamber portion 114 is larger than the vertical dimension of the lower deformable portion 115. The steam buffer chamber portion 114 and the lower deformable portion 115 correspond to the shapes of the steam inlet 111 at the generating end, respectively. For example, in the illustrated example, the steam buffer chamber portion 114 is a cylindrical part, i.e., cylindrical in shape, and the lower deformable portion 115 is an annular in shape.

[0087] 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 groove 116 is provided between the steam buffer chamber portion 114 and the sealing portion 115a, extending circumferentially along the steam generating end component 110 / sealing portion 115a. The opening of the first 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 groove 116 via the groove. The steam generating end component 110 can be movably and detachably installed to the cover plate seat 14 through the first groove 116. 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 first groove 116 can be annular in shape, and if needed and / or desired, the number of first grooves 116 can be more than two, each first groove 116 being arc-shaped.

[0088] 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 retaining 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 or assembled, 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 enhances the structural strength of the lower deformable portion 115 and ensures reliable sealing.

[0089] The steam generating end component 110 also includes a first interface portion 113 for connection with the main body component 120 of the supplementary cooking steam passage. The first interface portion 113 is connected to the steam buffer chamber portion 114 and communicates with the steam buffer chamber 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 the generating end steam outlet 112. The first interface portion 113 can receive a portion of the main body component 120 of the supplementary cooking steam passage, thereby increasing the sealing area between the first interface portion 113 and the main body component 120 of the supplementary cooking steam passage and improving the sealing effect. Figure 13 As shown, one end of the main component 120 of the supplementary steam channel is inserted into the first interface 113 via the steam outlet 112 at the generating end, with the insertion depth reaching the steam buffer chamber P11.

[0090] 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 main component 120 of the supplementary steam passage. Figure 12 As shown, the inner wall surface of the first interface portion 113 is provided with reinforcing ribs 101. The reinforcing ribs 101 are arranged circumferentially along the first interface portion 113. The reinforcing ribs 101 can be annular or dot-shaped and evenly distributed circumferentially along the first interface portion 113. By providing reinforcing ribs 101, the first interface portion 113 and the main component 120 of the supplementary steam passage are press-fitted, resulting in a better sealing effect. Alternatively, a groove can be provided between the first interface portion 113 and the upper mounting portion 117.

[0091] The steam generating end component 110 also includes a guide wall 119. The guide wall 119 is located at the top of the steam generating end component 110. The steam buffer chamber 114 has the guide wall 119, and the guide wall 119 is positioned opposite the steam inlet 111 of the generating end. The guide 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 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.

[0092] The steam buffer chamber 114 forms a steam buffer chamber P11, where supplementary cooking steam gathers and then flows out from the steam outlet 112 at the generating end. The steam buffer chamber P11 helps stabilize the pressure of the supplementary cooking steam, maintaining the dynamic pressure balance of the supplementary cooking steam output from the steam generating end component 110, thereby stably supplying supplementary cooking steam to the food cooking chamber and ensuring the stability and consistency of the food's moisture retention effect within the cooking chamber. The cross-sectional area of ​​the steam buffer chamber 114, taken from a plane perpendicular to the central axis AX1 of the generating end inlet, is S. 腔 The cross-sectional area of ​​the steam outlet 112 at the generator end, taken from a plane perpendicular to the central axis AX2 of the generator end 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 steam outlet 112 at the generating end, which effectively stabilizes the pressure of the supplementary cooking steam in the steam buffer chamber 114.

[0093] 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 steam outlet 112 of the generating end is facing the designated direction after the steam generating end component 110 is installed, so as to more accurately connect with the main component 120 of the supplementary steam channel. Even after multiple disassemblies and reassemblies, the connection accuracy can be guaranteed. This can prevent the main component 120 of the supplementary steam channel from being subjected to bending stress due to large coaxiality deviation during assembly, and avoid irreversible deformation of the main component 120 of the supplementary steam channel due to the influence of high temperature environment, thereby ensuring the sealing effect at the steam outlet 112 of the generating end.

[0094] The first positioning part 141 is located within the first 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 slot 116; more specifically, the vertical projection of the first positioning part 141 lies within the vertical projection of the first slot 116. The first positioning part 141 does not protrude beyond the first slot 116, and the first slot 116 can also engage with the cover plate seat mounting hole 20 at the first positioning part 141.

[0095] The first positioning part 141 is located near the steam outlet 112 at the generating end. Optionally, the first positioning part 141 is located vertically below the steam outlet 112 at the generating end. 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 steam outlet 112 at the generating end face the same direction, and the positioning and docking are on the same side of the steam generating end component 110, which facilitates rapid assembly.

[0096] 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. Optionally, the cross-sectional shape of the sealing portion 115a along the vertical plane is V-shaped, and the included angle is acute, for example, 30°≤ included angle≤60°. This can improve the deformation resistance of the lower deformable portion 115 and prevent the gas pressure in the steam generating device 40 from pushing up the sealing portion 115a, causing the seal to fail. 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 the steam inlet 111 of the generating end. A water storage cavity 142 is formed between the water storage portion 115b and the sealing portion 115a. The steam generating end component 110 can be better sealed by the sealing part 115a, and the condensate can be collected in the water storage cavity 142 formed by the water storage part 115b and the sealing part 115a. This prevents condensate from spilling when the steam generating end component 110 is disassembled, which would affect the user experience. Alternatively, the steam generating end component 110 may not have a water storage part 115b, and the end of the sealing part 115a may form the steam inlet 111.

[0097] The steam generating end component 110 has the function of changing the direction of the supplementary steam flow. The steam generating end inlet 111 has a central axis AX1, and the steam generating end outlet 112 has a central axis AX2. There is a spatial or planar angle α between the central axes AX1 and AX2. The central axes AX1 and AX2 are spatially and planarly, respectively. If they are not in the same plane, the angle α is spatial; if they are in the same plane, the angle α is planar. 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 steam generating end inlet 111 and the steam generating end outlet 112 have an angle of 90° or close to 90°.

[0098] This configuration allows the flow direction of the supplementary steam to be reversed at a right angle or near a right angle, for example, changing the flow direction of the supplementary steam from a roughly vertical direction to a roughly horizontal direction. Thus, the steam generating end component 110 engages with the main supplementary steam channel component 120 in a roughly horizontal direction. Compared to a vertical engagement, a horizontal engagement saves structural space in the vertical direction, which helps reduce the vertical dimensions of the steam channel assembly and consequently lowers the height of the cooking appliance 1. Furthermore, with a horizontal engagement, the vertical assembly and disassembly of the steam generating end component 110 are largely unobstructed by the main supplementary steam channel component 120, 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.

[0099] The following text combines Figure 8 , Figure 9 , Figure 14 and Figure 15 The structure of the main component 120 of the steam channel for supplementary cooking is described in detail.

[0100] like Figure 14 As shown, the main component 120 of the supplementary cooking steam channel includes a hollow channel component body 122, a channel steam inlet end 123, and a channel steam outlet end 124. The channel steam inlet end 123 is connected to one end of the channel component body 122, and the channel steam outlet end 124 is connected to the other end of the channel component body 122. The channel steam inlet end 123 can be detachably inserted into, overlapped with, or directly connected to one end of the generating end steam outlet 112 / output end component 130, and the channel steam outlet end 124 can be detachably inserted into, overlapped with, or directly connected to the output end supplementary cooking steam inlet 132. The channel steam inlet end 123 and the channel steam outlet end 124 form a tubular section, and the outer cross-sectional dimension of the tubular section is smaller than the outer cross-sectional dimension of the channel component body 122. This facilitates the insertion and separation of these two mating ends with the corresponding end seals, making the assembly and disassembly of the supplementary cooking steam channel main component 120 easier. For the illustrated example, the cross-sectional shape of the main component 120 of the supplementary steam channel is circular, so that the outer diameter of the tubular part is smaller than the outer diameter of the main body 122 of the channel component.

[0101] 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.

[0102] The channel connector 121 includes a support portion 128, which is connected to at least one side of the main body component 120 of the supplementary steam channel at its center. The support portion 128 is supported on the top of the support member 23. Optionally, the channel connector 121 is provided with a fastening hole 129, specifically, the support portion 128 is provided with a fastening hole 129, which is located on the first side of the main body component 120 of the supplementary steam channel at its center. Figure 8 As shown, the support member 23 is provided with a fastening post 25, and the detachable cover assembly 12 includes a fastener, which passes through the fastening hole 129 and is locked to the fastening post 25. The channel connector 121 is provided with a snap-fit ​​part 143, which is located on the second side of the main body member 120 of the supplementary steam channel at the middle. Figure 9 As shown, the support member 23 has a groove 26 with the groove opening facing horizontally. In the assembled state, the snap-fit ​​part 143 is snapped into the groove 26. 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.

[0103] 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 outer shape of the main body member 120 of the supplementary steam channel. The central axis of the channel limiting opening 27 is approximately parallel to the extension direction of the main body member 120 of the supplementary steam channel. The main body member 120 of the supplementary steam channel is partially limited by the channel limiting opening 27.

[0104] The following text combines Figure 7 and Figure 16 The structure of the output component 130 is described in detail.

[0105] like Figure 16As shown, the output end component 130 has the function of changing the direction of the supplementary cooking steam flow. The output end supplementary cooking steam inlet 132 faces horizontally and is opposite to the direction of the generating end steam outlet 112. There is a spatial or planar angle α between the central axis of the output end supplementary cooking steam outlet 131 and the central axis of the output end supplementary cooking steam inlet 132. The angle α can be 85°≤α≤95°. For example, suitable values ​​for the angle α include 85°, 86°, 88°, 90°, 92°, 94°, and 95°. The central axes of the output end supplementary cooking steam outlet 131 and the output end supplementary cooking steam inlet 132 have an angle of 90° or close to 90°. This configuration allows the flow direction of the supplementary cooking steam to be changed from a roughly horizontal direction to a roughly vertical direction. Thus, the output end component 130 is joined to the main component 120 of the supplementary steam channel in a generally horizontal direction. Compared with the vertical joining method, the horizontal joining method saves structural space in the vertical direction, which is beneficial to reducing the vertical size of the steam channel assembly and thus reducing the height of the cooking appliance 1. Furthermore, by using the horizontal joining method, the disassembly and assembly of the output end component 130 in the vertical direction is not significantly obstructed by the main component 120 of the supplementary steam channel, making it more convenient to disassemble and assemble the output end component 130 separately.

[0106] Optionally, the central axis of the supplementary steam inlet 132 at the output end is approximately collinear with the central axis of the steam outlet 112 at the generating end. This prevents the main component 120 of the supplementary steam channel from being subjected to bending stress due to large coaxiality deviations during assembly, avoids irreversible deformation of the main component 120 of the supplementary steam channel due to high-temperature environments, and thus ensures the sealing effect at the two supplementary steam interfaces. The supplementary steam output section channel P13 and / or the cooking steam exhaust channel P21 extend at least partially in the vertical direction. The output component 130 has a certain dimension in the vertical direction to facilitate docking with adjacent components; the vertical channel formed by the output component 130 can transport supplementary steam and / or cooking steam in the vertical direction.

[0107] The output end 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 cooking steam output section channel P13 and a cooking steam exhaust channel P21. Specifically, the partition wall 137 and a portion of the cylindrical body 136 adjacent to the output end supplementary cooking steam inlet 132 form the supplementary cooking steam output section channel P13, and the partition wall 137 and another portion of the cylindrical body 136 form the cooking steam exhaust 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 cooking steam output section channel P13.

[0108] 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 slot 138 for mounting the output end component 130. The second slot 138 extends circumferentially along the output end component 130, and the opening of the second slot 138 faces away from the interior of the columnar body 136. The second slot 138 is annular in shape. The edge of the cover plate mounting hole 21 is engaged with the second slot 138 via the slot. Specifically, the bottom of the columnar body 136 is provided with a second slot 138 for mounting the output end component 130. The second slot 138 extends circumferentially along the output end component 130, and the opening of the second 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 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.

[0109] 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 slot 138. The portion of the fixing part 139 used to form the second slot 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.

[0110] The output end component 130 also includes a second interface portion 135 for connecting to the main component 120 of the supplementary cooking steam passage. The second interface portion 135 is located on the columnar main body 136 and communicates with the supplementary cooking steam output section passage P13. The second interface portion 135 extends horizontally for a predetermined length, and its port constitutes the output end supplementary cooking steam inlet 132. The second interface portion 135 can receive a portion of the main component 120 of the supplementary cooking steam passage, thereby increasing the sealing area between the second interface portion 135 and the main component 120 of the supplementary cooking steam passage and improving the sealing effect. Figure 7 As shown, the other end of the main component 120 of the supplementary steam channel is inserted into the second interface portion 135 via the output supplementary steam inlet 132, with the insertion depth reaching the steam buffer chamber P11. The inner wall surface of the second interface portion 135 is also provided with reinforcing ribs 101. The reinforcing ribs 101 are arranged circumferentially along the second interface portion 135.

[0111] like Figure 16 and Figure 17As shown, the output end component 130 also includes an upper deformable portion 144, which is disposed at the top of the output end component 130. The upper end of the upper deformable portion 144 forms an upward-facing output end cooking steam outlet 134. The upper deformable portion 144 can correspond to the cooking steam passage 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 passage component 32 communicates with the cooking steam exhaust passage P21 via the liner steam outlet 29. The upper deformable portion 144 can be connected to the top of the columnar body 136.

[0112] The following text combines Figure 3 , Figure 4 and Figure 18 The structure of the infrared heating device 200 is described in detail.

[0113] The infrared heating device 200 includes an infrared heating element 210. For example, the infrared heating element is encapsulated in a glass tube to form the infrared heating element 210. In this example, the infrared heating device 200 also includes a light-transmitting insulating plate 220 disposed below the infrared heating element 210. Some alternative examples include an electrically conductive heating film disposed on a plate-like member; in this example, the plate-like member used to dispose of the heating film is at least partially light-transmitting. Alternatively, the infrared heating device 200 includes a radiating plate and a heating assembly for heating the radiating plate. Heat generated by the heating assembly can be transferred to the radiating plate, and the heated radiating plate can radiate infrared rays into the food cooking cavity.

[0114] Taking the illustrated example, the structure of the cover 3 is further described. The partition plate 220 is installed at the inner lining through-hole 30. The cover plate 13 is positioned below the partition plate 220. The cover plate through-hole 19 corresponds to the position of the partition plate 220. In other words, the cover plate through-hole 19 is located directly below the partition plate 220. Infrared rays generated by the partition plate 220 can radiate towards the inner pot 4 through the inner lining through-hole 30 and the cover plate through-hole 19.

[0115] The liner 9 may be provided with a support portion 9a. The support portion 9a is disposed around the through hole 30 of the liner, and the support portion 9a forms a closed annular structure. The outer edge of the isolation plate 220 can overlap the bottom wall of the support portion 9a and abut against the side wall of the support portion 9a. The support portion 9a can provide an upward supporting force to the isolation plate 220 and restrict the horizontal movement of the isolation plate 220, which facilitates the fixation of the isolation plate 220. Optionally, the support portion 9a can be recessed downward, and the isolation plate 220 is accommodated in the recessed support portion 9a. A peripheral sealing ring 221 is fitted on the outer periphery of the isolation plate 220 to form a seal between the isolation plate 220 and the liner 9. The infrared heating device 200 also includes a fixing member 230. The fixing member 230 can be connected to the liner 9, and the outer edge of the isolation plate 220 is sandwiched between the fixing member 230 and the support portion 9a. The fastener 230 may optionally be configured as a ring, which can be connected to the liner 9 by a suitable means such as snap-fit, fastener connection such as screws, or welding.

[0116] The liner 9 has a recess 28 for receiving the steam passage assembly 100. The recess 28 is located behind the through-hole 30 in the liner and is recessed upward from the lower surface of the liner 9. At least a portion of the steam passage assembly 100 is received within the recess 28. The size and shape of the recess 28 are adapted to the outer contour of the steam passage assembly 100.

[0117] It should be noted that the terms "approximately" and "basically" used to describe the orientation of components above refer to a fluctuation of ±5° relative to the specified direction. For example, "approximately horizontal" means the angle with the horizontal direction is within ±5°. 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 supply channel P1 and the cooking steam exhaust channel P2 are made of food-grade materials.
