Description

Technical Field

[0001] This application relates to the technical field of kitchen appliances, and more specifically, to a cooking appliance with automatic drainage. Background Technology

[0002] In existing cooking appliances with drain valves, to reduce the area occupied by the drain valve on the heating element, it is usually positioned near the center of the inner pot, allowing for even heating of the bottom of the inner pot around the drain valve. The drain valve directs water or liquid from the inner pot to the wastewater box; therefore, the drain hole of the drain valve is connected to the inlet hole of the wastewater box. There are typically two types of drain valve installation: one with a protruding mounting cavity on the bottom of the inner pot, and the other with a recessed mounting cavity on the bottom of the inner pot. The first type of drain valve installation makes it difficult to completely drain water from the bottom of the inner pot, making it difficult to control the amount of water remaining in the inner pot and thus hindering proper control of the cooking process.

[0003] The second type of drain valve installation, where the drain valve mounting cavity protrudes from the bottom of the inner pot, increases the difficulty of placing the inner pot into the cooking appliance. If the inner pot is not properly placed inside the cooking appliance, the liquid discharged from the drain valve may splash into the interior of the cooking appliance instead of flowing normally into the wastewater box, thus affecting the normal operation of the internal electronic components. Chinese patent CN106308472B proposes an electric rice cooker with rice water separation function. By setting a guide nozzle in the center of the bottom plate of the inner pot, which cooperates with the liquid collection part inside the cooking appliance, the rice water in the inner pot can be smoothly collected into the rice water storage box. The spout contains a metal ball, which is attracted by a magnet to open the spout and drain the rice water. The lower part of the spout is shaped like an inverted frustum to better hold the metal ball and prevent it from falling off when the inner pot is being removed. However, the spout on the inner pot directly engages with the liquid collection part at the bottom of the cooking appliance. This requires the vertical dimension of the spout to be relatively large to fit into the liquid collection part at the bottom of the cooking appliance, making it inconvenient for users to use and difficult to store. Furthermore, during the draining process, since there is no obstruction between the spout and the heating element, the liquid or steam flowing from the spout may splash or come into contact with the heating element and other electronic components, potentially causing a short circuit and affecting the operation of the rice cooker. Utility Model Content

[0004] The purpose of this application is to provide a cooking appliance with automatic drainage. By placing the valve housing of the valve assembly inside the receiving channel, and the lower end of the receiving channel extending into the docking channel of the base, the required extension length of the drainage assembly is transferred through the receiving channel. The drain outlet of the drainage assembly is located inside the receiving channel, thereby ensuring that the liquid discharged from the drainage assembly flows smoothly from the receiving channel into the docking channel without needing to extend the drain outlet of the drainage assembly into the docking channel. This solves the problem of the large vertical dimension of the drain valve assembly at the outer bottom of the inner pot in existing cooking appliances with drain valves, and also provides a certain degree of protection for the drainage assembly and electronic components.

[0005] The embodiments of this application are implemented as follows:

[0006] This utility model provides a cooking appliance with automatic drainage, including a pot body and a heating element disposed on the pot body. The pot body is provided with an inner pot, and a drainage component is provided with a downward protruding bottom of the inner pot. The drainage component has a drain outlet at its bottom. The drainage component includes a valve assembly and a valve shell. The valve assembly is located inside the valve shell. The pot body also includes a base. The heating element extends downward and is provided with a receiving channel. The valve shell is located inside the receiving channel. The base has a vertically extending docking channel. The lower end of the receiving channel extends into the docking channel. The drain outlet is higher than the lower end of the receiving channel.

[0007] In a preferred embodiment, a sealing structure is provided at the connection between the docking channel and the receiving channel.

[0008] In a preferred embodiment, the heating element is an electromagnetic coil, and at least one set of coil windings is wound on the side of the electromagnetic coil facing away from the inner pot.

[0009] In a preferred embodiment, the system further includes a driving device and a water-adding mechanism for adding water to the inner pot. The driving device is used to drive the drain assembly to open the drain outlet. The water-adding mechanism includes a water inlet, and in the vertical direction, the projection area of ​​the drain outlet and the projection area of ​​the water inlet are offset.

[0010] In a preferred embodiment, the drainage assembly includes a spherical valve core that blocks the drain outlet to form a seal at the drain outlet, wherein the projected area of ​​the spherical valve core is located within the projected area of ​​the receiving channel in the vertical direction.

[0011] In a preferred embodiment, the valve assembly is detachably fixed to the valve housing from the inner pot, and the valve assembly further includes a filter valve cover, with a limiting bracket below the filter valve cover for limiting the valve core.

[0012] In a preferred embodiment, a first sealing ring is further provided at the drain outlet, and the spherical valve core blocks the through hole of the first sealing ring. The first sealing ring is sleeved on the drain outlet, or the outer side of the first sealing ring abuts against the outer periphery of the drain outlet.

[0013] In a preferred embodiment, the system further includes a wastewater box located below the docking channel, with the inlet of the wastewater box corresponding to the docking channel.

[0014] In a preferred embodiment, the valve housing is integrally formed on the bottom of the inner pot, or the valve housing is a separately manufactured metal part, and the valve housing is fixedly connected to the bottom of the inner pot.

[0015] In a preferred embodiment, the main structure of the valve housing and / or the main structure of the accommodating channel is a cylindrical structure.

[0016] The advantages of this application compared to the prior art are:

[0017] This application provides an automatic drainage cooking appliance to solve the problem that the drainage valve assembly of existing inner pots with drainage valves has an excessively large vertical dimension at the bottom. A receiving channel extending downwards from the heating element accommodates the valve housing of the drainage assembly, thereby reducing the length of the drainage assembly that would otherwise need to extend into the liquid collection section. Furthermore, since the lower end of the receiving channel extends into the docking channel, it prevents the drainage assembly from colliding with the docking channel. Because the lower end of the receiving channel extends into the docking channel and the receiving channel extends downwards from the heating element, liquid or steam flowing from the lower end of the receiving channel is less likely to flow back or splash onto the terminals or other electronic components on the heating element, thus providing a certain degree of isolation and protection.

The technical solutions of this application will now be clearly and completely described in conjunction with the accompanying drawings.

[0027] With modern people increasingly focusing on healthy eating, household cooking utensils have become an indispensable tool for cooking. To reduce the sugar content in people's diets, a type of cooking utensil that can drain water or liquids containing sugar produced during cooking has been developed. This effectively reduces the sugar content of food. For example... Figure 1 As shown, the cooking appliance 100 typically includes a pot body 1 and an inner pot 2 located inside the pot body 1. A drain assembly 3 protrudes from the bottom of the inner pot 2. Its working principle is: the valve of the drain assembly 3 is opened and closed by the control module, thereby determining the amount of liquid discharged from the inner pot 2.

[0028] In existing inner pots 2 with drainage components 3, when the drainage program is started, in order to discharge the water in the inner pot 2 through the drainage components 3 and direct the discharged water to a suitable position in the cooking appliance 100, the prior art extends the length of the drainage components 3 and makes the lower part of the drainage components 3 into a guide shape, so that the drain outlet 301 of the drainage components 3 is directed to the liquid collection part. However, the excessively long drainage components 3 will affect the user's use of the inner pot 2, and the drainage components 3 are prone to collision with other parts or parts such as the liquid collection part, causing damage. Furthermore, the liquid or steam flowing out of the drainage components 3 may splash or come into contact with electrical components, affecting the normal operation of the cooking appliance. There is an urgent need for a cooking appliance solution with drainage components 3 that solves the aforementioned problems.

[0029] This utility model provides a cooking appliance 100 with automatic drainage, such as... Figure 1 and Figure 2As shown, the device includes a pot body 1 and a heating element 4 disposed on the pot body 1. The pot body 1 is provided with an inner pot 2. The bottom of the inner pot 2 is provided with a downward protruding drainage component 3. The bottom of the drainage component 3 is provided with a drain outlet 301. The drainage component 3 includes a valve component 302 and a valve housing 303. The pot body 1 also includes a base 101. The heating element 4 extends downward and is provided with a receiving channel 401. The valve housing 303 is located in the receiving channel 401. The base 101 has a vertically extending docking channel 1011. The lower end of the receiving channel 401 extends into the docking channel 1011. The receiving channel 401 extends into the docking channel 1011 and ensures that the drain outlet 301 is higher than the lower end of the receiving channel 401. In this way, by setting the receiving channel 401, the vertical dimension of the drainage component 3 can be reduced. Through the docking of the receiving channel 401 and the docking channel 1011, the liquid drained by the drainage component 3 first flows into the channel of the receiving channel 401, and then flows into the docking channel 1011 from the opening at the lower end of the receiving channel 401. Then, it flows into the designated position of the base 101 (such as the wastewater box) or flows out to the outside from the docking channel 1011. The receiving channel 401 can prevent the drainage component 3 from colliding with the docking channel 1011. Furthermore, since the lower end of the receiving channel 401 extends into the docking channel 1011 and the receiving channel 401 extends downward from the heating element 4, the liquid or steam flowing out from the lower end of the receiving channel 401 is less likely to flow back or splash onto the terminals or other electronic components on the heating element 4. The receiving channel 401 plays a certain role in isolation and protection. It is understandable that the liquid falling from the drain outlet 301 of the drainage component 3 will fall more straight down under the action of gravity, falling into the receiving channel 401 and the subsequent docking channel 1011. Therefore, when the lower opening of the receiving channel 401 is flush with the upper inlet of the docking channel 1011, it should also be understood that the lower end of the receiving channel 401 mentioned in this utility model extends into the docking channel 1011. It is also understandable that the automatic drainage cooking appliance 100 provided by this utility model means that when the cooking appliance 100 needs to drain, the drain component 3 can be controlled by the control module to open the valve to drain the water. This will not be elaborated further here.

[0030] Understandably, existing cooking appliances 100 typically have a base 101, which can support or house the main components required by the cooking appliance 100, such as the pot body 1, inner pot 2, heating element 4, water filling mechanism 6, wastewater box 7, and clean water tank 8. The water filling mechanism 6 adds clean water from the clean water tank 8 to the inner pot 2. When drainage is needed, the drainage component 3 directs the liquid in the inner pot 2 along the internal channel of the drainage component 3 into the receiving channel 401, then into the docking channel 1011, and finally into the wastewater box 7. This achieves an automatically draining cooking appliance 100. It is known that the docking channel 1011 can... Any physical structure formed within the base 101 can protrude from an isolation plate, which separates the upper pot body 1 from the lower wastewater box 7. This can be any conventional means used by those skilled in the art, or it can be a docking channel 1011 formed by the structure of the wastewater box 7 itself. As long as the docking channel 1011 extends from the base 101 and the lower end of the accommodating channel 401 extending downward from the heating element 4 is inserted into the docking channel 1011 to drain the liquid in the inner pot 2 into the wastewater box 7 or other places, thereby reducing the vertical dimension of the drainage component 3, there are no restrictions here.

[0031] In some embodiments, such as Figure 1 As shown, a sealing structure 5 is provided at the connection between the docking channel 1011 and the receiving channel 401. After the sealing structure 5 seals or blocks the connection between the two, liquid falling from the drain outlet 301 or steam flowing in the channel cannot contact the components or parts outside the receiving channel 401, thus protecting the electronic components inside the cooking appliance 100 and reducing the humidity inside the pot 1, making the components less susceptible to corrosion and extending the service life of the cooking appliance 100. In some examples, the sealing structure 5 is a silicone sealing ring, which can be fitted onto the top of the docking channel 1011 or the bottom of the receiving channel 401. The silicone sealing ring has a simple structure and is easy to fit and replace. In other examples, the sealing structure 5 is a sleeve ring, which is fitted onto the connection between the docking channel 1011 and the receiving channel 401, thereby completely covering the gap at the connection to prevent liquid splashing or steam overflowing from the connection. In addition, the sealing structure 5 can also be supported on other physical structures of the base 101, thereby making the installation of the sealing structure 5 more stable and the sealing effect better.

[0032] In some embodiments, the heating element 4 is an electromagnetic coil. It is understood that the electromagnetic coil includes at least a coil frame and a coil winding. In this case, the accommodating channel 401 can be formed by a downwardly recessed portion of the coil frame. Alternatively, the electromagnetic coil may also include a base. In cooking appliances such as rice cookers, the inner pot 2 is placed on the base. The side of the base facing away from the inner pot 2 has a coil frame or a coil winding directly wound on it, depending on the actual needs. It is understood that the inner pot 2 is heated from below by the heating element 4. Therefore, as long as the heating element 4 is generally used to heat the inner pot 2, it should be within the scope of this utility model. At least one set of coil windings is wound on the side of the electromagnetic coil facing away from the inner pot 2. This set of coil windings heats the inner pot 2, which is made of a metal material with magnetic conductivity, ensuring that the food in the inner pot 2 is heated. In other embodiments, the heating element 4 is a simpler heating plate structure. The heating plate contains heating elements by embedding heating wires, heating tubes, etc. The power supply terminals of the heating elements are usually located on the side of the plate away from the object being heated. A receiving channel 401 can be integrally cast and recessed in the middle or other parts of the plate. Those skilled in the art can understand how to make the receiving channel 401 after reading this utility model, so it will not be described in detail here.

[0033] In some embodiments, such as Figure 2 and Figure 3 As shown, the cooking appliance 100 also includes a drive device 6, which drives the drain assembly 3 to open the drain outlet 301. The valve assembly 302 includes a valve core 3021. The valve core 3021 blocks the drain outlet 301 when the valve assembly 302 is in the closed state. The valve assembly 302 can switch from the closed state to the open state through a contact drive structure or a non-contact drive structure. For example, through a contact push rod drive structure, when it is necessary to open the drain outlet 301, the push rod extends into the drain outlet 301 to push open the valve core 3021; ​​or through a non-contact electromagnetic drive structure, such as using ferromagnetic material or other materials that can be attracted by magnets to make the main body structure of the valve core 3021. An electromagnet or movable magnet structure is provided on the outer periphery of the drainage component 3. When the electromagnet is energized or the movable magnet structure moves the adsorption magnet to a set position, the magnetic force attracts or repels the valve core 3021 to the state of not blocking the drain outlet 301. At this time, when the drive device releases the state of opening or attracting (repelling) the valve core 3021, the valve core 3021 will return to the blocked state of blocking the drain outlet 301 due to its own weight (in other embodiments, there may be other attractive forces), that is, it switches from the open state of the valve component 302 to the closed state. The setting of the drive device 6 can be selected according to actual needs and is not limited here, as long as it can meet the needs of moving the valve core 3021.

[0034] In some embodiments, such as Figure 1 and Figure 2 As shown, it also includes a water-adding mechanism 6 for adding water to the inner pot 2. The water-adding mechanism includes a water inlet 601, which is located on the inner cover 102 of the pot body 1. In other embodiments, the water inlet 601 can also be located at other positions on the pot body 1, as long as it can satisfy the requirement of adding water to the inner pot 2. In the vertical direction, the projection area of ​​the drain outlet 301 is offset from the projection area of ​​the water inlet 601. In this way, the water flowing into the inner pot 2 from the water inlet 601 is less likely to directly rush towards the drain outlet 301, reducing the impact of the water flow on the valve assembly 302 located in the valve housing 303. In some cooking programs, it can also prolong the time for water to flow out of the inner pot 2, which can improve cooking efficiency to a certain extent. More specifically, the drain assembly 3 is located in the central area of ​​the bottom of the inner pot 2, and the water inlet 601 is arranged around the outer periphery of the central area. In this way, after the water flows into the interior of the inner pot 2 from the water inlet 601, it will flow from the outer periphery to the drain assembly 3 in the central area, thereby providing uniformity of water flow in the inner pot 2, making the food inside the inner pot 2 more intact, and rinsing, soaking or heating more even.

[0035] In some embodiments, the valve core 3021 moves upward and outward from the state of blocking the drain outlet 301 to the state of not blocking the drain outlet 301. That is, the valve core 3021 moves both vertically and laterally to control whether the drain outlet 301 is blocked. This increases the degree to which the drain outlet 301 is opened in the open state and reduces the degree to which the valve core 3021 obstructs the drain outlet 301, making drainage smoother and less prone to jamming. Figure 3As shown, the valve core 3021 is a spherical valve core that blocks the drain outlet 301 to form a seal at the drain outlet. In the vertical direction, the projection area of ​​the spherical valve core is located within the projection area of ​​the receiving channel 401. In this way, the size of the valve assembly 302 is not too large, thus not occupying a large area of ​​the bottom of the inner pot 2, so that the heating element 4 can have sufficient heating area to heat the inner pot 2. It can be understood that in this embodiment, the projection area of ​​the spherical valve core is always located within the projection area of ​​the receiving channel 401 when the valve assembly 302 is in the closed and open states. That is, even when the spherical valve core does not block the drain outlet 301, the projection area of ​​the spherical valve core will not intersect or move away from the projection area of ​​the receiving channel 401. When the valve assembly 302 is in the open state, if the projected area of ​​the spherical valve core intersects with the projected area of ​​the receiving channel 401, it means that the spherical valve core is located directly above the inner wall of the receiving channel 401. Therefore, when liquid flows from the inner pot 2 into the drain assembly 3, and when the vertical dimension of the drain assembly 3 is small, the vertical distance between the spherical valve core and the drain outlet 301 is small. The liquid flowing through the spherical valve core will splash more onto the inner wall of the receiving channel 401 due to the guidance of the spherical surface. This results in a higher degree of dirt on the inner wall of the receiving channel 401 after the cooking appliance 100 has been used, increasing the difficulty of cleaning for the user. Whether increasing the vertical distance between the spherical valve core and the drain outlet 301 or making the projected area of ​​the spherical valve core farther away from the projected area of ​​the receiving channel 401, it will lead to an increase in the size of the drain assembly 3, which is not conducive to the heating of the inner pot 2. Therefore, this solution controls the position of the spherical valve core so that the projected area of ​​the spherical valve core is located within the projected area of ​​the receiving channel 401, whether the valve assembly 302 is in the open or closed state. This can reduce the degree of dirt on the inner wall of the receiving channel 401 to a certain extent, and also reduce the size of the drain assembly 3, ensuring good heating performance and smooth drainage of the inner pot 2.

[0036] In some embodiments, when the valve assembly 302 switches from the open valve state to the closed valve state, that is, when the valve core 3021 needs to switch from the unblocked drain port 301 state to the blocked drain port 301 state, when a spherical valve core is used, due to the spherical structure, the spherical valve core is easy to roll and reset under its own weight, which is more conducive to the valve core 3021 blocking the drain port 301 by its own weight in the closed valve state of the valve assembly 302, and the blocking is reliable.

[0037] In some embodiments, the drain port 301 is located at the bottom of the valve housing 303, or at the bottom of the limiting bracket 3023 of the valve assembly 302. This is only necessary if the valve core 3021, when blocking the drain port 301, prevents liquid in the inner pot 2 from flowing out through the drain port 301; no specific limitation is imposed here. The valve assembly 302 also includes a first sealing ring 3022, which is disposed at the drain port 301, thereby enabling the drain assembly 3 to stably seal its lower drain port 301 during non-drainage periods. Figure 3 As shown, the valve core 3021 is a spherical valve core. The spherical valve core blocks the through hole of the first sealing ring 3022. In this embodiment, the first sealing ring 3022 is sleeved on the drain outlet 301. In other embodiments, the outer side of the first sealing ring can also abut against the outer periphery of the drain outlet 301. The specific choice can be made according to actual needs.

[0038] In some embodiments, the valve assembly 302 is detachably fixed to the valve housing 302 from the inner pot 2. The valve assembly 302 includes a filter valve cover 3024, and a limiting bracket 3023 for limiting the valve core 3021 is provided below the filter valve cover 3024. The bottom of the drainage assembly 3 is provided with a drain port 301. The valve core 3021 blocks the drain port, thereby forming a seal at the drain port 301. When the valve core 3021 is driven by the driving device 6 to switch to a state away from the drain port 301, the drain port 301 is opened, and the liquid in the inner pot 2 can flow out of the inner pot 2 from the drain port. It can be understood that, since the limiting bracket 3023 is used to limit the valve core 3021, from This allows the valve core 3021 to be simultaneously removed when the limiting bracket 3023 is taken out. In this way, the valve assembly 302 can be removed from the valve housing 303, while the valve core 3021 of the valve assembly 302 is limited by the limiting bracket 3023. Removing the limiting bracket 3023 will also take out the valve core 3021, making it convenient for users to remove the valve assembly 302 and clean it. This ensures the cleanliness of the drainage assembly 3, reduces the impact of food residue and other residues on the sealing effect of the valve core 3021 on the drain outlet 301, ensures the stable implementation of the drainage function and the hygiene of the cooking appliance 100, and greatly improves the user experience of this type of cooking appliance with automatic drainage. Meanwhile, since the valve assembly 302 is detachably fixed within the valve housing 303 from the inner pot 2, the valve assembly 302 needs to be removed from the inside of the inner pot 2. This means the valve assembly 302 needs to be placed from top to bottom at the bottom of the inner pot 2 and supported by the inner pot 2 and / or the valve housing 303. The valve assembly 302 cannot be removed from the outer bottom of the inner pot 2, thus ensuring that it cannot fall out and is not easily lost. Furthermore, because the valve assembly 302 is placed inside the valve housing 303, the valve housing 303 can protect the valve assembly 302 to a certain extent and ensure that it is stably placed at the bottom of the inner pot 2, preventing it from shaking and ensuring its service life and functionality, further guaranteeing the working life of the cooking appliance 100. When the first sealing ring 3022 is fitted onto the drain outlet 301, it is convenient to remove the valve assembly 302 from the inside of the inner pot 2. The valve assembly 302 and the first sealing ring 3022 can be removed together for cleaning, which improves the user's ease of operation.

[0039] In some embodiments, when the limiting bracket 3023 and the filter valve cover 3024 are detachably connected, they can be connected by threads or snaps. This allows the limiting bracket 3023 and the valve core 3021 within it to be removed simultaneously with the removal of the filter valve cover 3024, enabling the valve assembly 302 to be removed as a single unit. This increases user convenience and makes the valve assembly 302 easier to clean. Furthermore, since the filter valve cover 3024 and the limiting bracket 3023 are detachably connected, after the user removes the valve assembly 302, the filter valve cover 3024 can be opened to remove the valve core 3021 from the limiting bracket 3023. This facilitates direct cleaning of the valve core 3021. Because the valve core 3021 blocks the drain outlet 301, the cleaning requirements for the valve core 3021 are higher. Therefore, direct cleaning of the valve core 3021 ensures the proper functioning of the drain assembly 302. The function is realized; in some other embodiments, when the limiting frame 3023 and the filter valve cover 3024 are integrally made, the assembly difficulty of the valve assembly 302 can be reduced, and it is also convenient for the user to directly remove the valve assembly 302. At this time, the valve core 3021 can be reliably limited in the cavity formed by the limiting frame 3023 and the filter valve cover 3024, so that the valve core 3021 is not easy to lose; in some other embodiments, when the limiting frame 3023 and the filter valve cover 3024 are separate structures, that is, there is no connecting structure between the limiting frame 3023 and the filter valve cover 3011, the connecting structure is reduced, and when the automatic drainage cooking appliance 100 provided by this utility model is used for a long time, the gaps that can hide dirt due to the connecting structure itself are eliminated, making the valve assembly 302 more resistant to dirt and with a longer service life. In some other embodiments, the outer periphery of the limiting member 3023 is provided with a second sealing ring 3025 that cooperates with the inner wall of the valve housing 303. The second sealing ring 3025 can seal the gap between the outer periphery of the limiting member 3023 and the inner wall of the valve housing 303, so that the liquid in the inner pot 2 flows out when the valve core 3021 of the valve assembly 302 opens the drain port 301. This ensures that the drain assembly 3 can accurately control the draining process in the inner pot 2 through the valve assembly 302, and can prevent the valve assembly 302 from shaking in the valve housing 303, making the placement of the valve assembly 302 more stable and ensuring the function of the valve assembly 302.

[0040] In some embodiments, such as Figure 1As shown, it also includes a wastewater box 7, which is located below the docking channel 1011. The inlet 701 of the wastewater box 7 is correspondingly set to the docking channel 1011. The docking channel 1011 is connected to the receiving channel 401. Therefore, the liquid falling from the receiving channel 401 will quickly fall into the wastewater box 7 from the inlet 701. The wastewater box 7 collects the fallen liquid. After use, the user can easily take out the wastewater box 7 to directly pour out the unwanted liquid and clean the wastewater box 7, thus improving the function of the cooking appliance 100. It eliminates the need to connect the docking channel 1011 to an external wastewater collection point (such as a sewer or kitchen sink), reducing the complexity of the cooking appliance 100.

[0041] In some embodiments, the valve housing 303 is integrally formed on the bottom of the inner pot 2. This has the advantage of making the valve housing 303 more stable and less prone to falling off, further ensuring the functionality of the drainage assembly 3. In some other embodiments, the valve housing 303 is a separately manufactured metal part or metal assembly, which is fixedly connected to the bottom of the inner pot 2. Specifically, the valve housing 303 is installed at the location of the mating hole 201 opened at the bottom of the inner pot 2. This has the advantage that the formation of the valve housing 303 does not depend on the size parameters of the inner pot 2 itself, and the size parameters and shape of the valve housing 303 can be controlled according to actual design needs, making the structure of the drainage assembly 3 more reasonable and its performance more stable.

[0042] In some embodiments, such as Figure 2 and Figure 3 As shown, the vertical dimension of the valve housing 303 is smaller than that of the receiving channel 401, allowing the receiving channel 401 to completely accommodate the valve housing 303. The main structure of the valve housing 303 and / or the main structure of the receiving channel 401 are cylindrical structures. These cylindrical structures make the corresponding surfaces easy to clean and less prone to staining. Here, "main structure" refers to the middle section of the valve housing 303 and the receiving channel 401. For the valve housing 303, this middle section primarily accommodates the valve assembly 302. For the receiving channel 401, this middle section accommodates the valve housing 303. When both adopt cylindrical structures, the connection between the valve housing 303 and the receiving channel 401 is smoother.
