[0019] The second aspect of the application provides a cooking appliance, comprising a pot body assembly, further comprising a cover body assembly of the cooking appliance according to any one of the above embodiments, and the cover body assembly is openably and closably arranged on the pot body assembly.
[0020] Compared with the prior art, the technical scheme provided in the embodiments of the application has at least the following advantages:
[0021] 1. By providing a gas pump and a pipe assembly on the cover, the air inlet of the gas pump is communicated with the outside world, the air outlet of the gas pump is communicated with the pipe assembly, the steam valve is formed with a plug-in port, the pipe assembly passes through the plug-in port, and an air inlet communicated with the inner cavity of the pot body is formed. In this way, the gas pump can pump the outside cold air into the inner cavity of the pot body through the pipe assembly. The temperature difference between the cold air and the foam generated in the inner cavity of the pot body causes the steam in the foam to liquefy and shrink to break, thereby achieving the purpose of preventing overflow. The pipe assembly is plugged into the plug-in port formed on the steam valve, so that the air inlet formed on the pipe assembly for the cold air to enter is arranged close to the steam inlet of the steam valve communicated with the cooking cavity. In this way, on the one hand, the distance between the cold air inlet and the steam inlet can be reduced, thereby shortening the distance of the cold air flowing to the steam inlet through the inner surface of the cover assembly, and further reducing the amount of rice soup and other substances adhering to the inner surface of the cover assembly during the flow process, which is beneficial to maintaining the cleanliness of the inner surface of the cover assembly. On the other hand, it can also ensure that the cold air can better mix with the foam at the steam inlet for breaking, reduce the amount of foam that has not yet mixed with the cold air in the inner cavity of the pot body and overflows from the steam outlet of the steam valve, thereby achieving better breaking and preventing overflow effect.
[0022] 2. By arranging the plug-in port on the steam valve corresponding to and communicated with the steam inlet, and the pipe assembly passing through the plug-in port and the steam inlet in turn, the steam inlet forms an annular steam inlet surrounding the pipe assembly, so that the cold air inlet and the annular steam inlet are arranged at the same place. The annular steam inlet can increase the contact area between the steam and the pipe wall of the pipe assembly. The steam will break when it contacts with the pipe wall with relatively low temperature, thereby increasing the probability of breaking. The cold air in the pipe assembly will continuously lower the temperature of the annular steam inlet through the pipe wall of the pipe assembly, thereby increasing the probability of bubble breaking when the steam flows through the annular steam inlet, and further achieving better breaking and preventing overflow effect. Secondly, the cold air inlet and the annular steam inlet are arranged at the same place, so that the cold air can spread evenly in three dimensions after entering the inner cavity of the pot body, and the air cooling breaking effect is better. In addition, it can also reduce the steam flow in other horizontal areas, so that the rice soup is not easy to adhere to the inner surface of the cover assembly, thereby improving the cleanliness of the cover assembly in use.
[0023] 3. The pipe assembly comprises an adapter, a pipe body and a first sealing member. The pipe body is connected with the gas pump through the adapter, and the adapter and the pipe body are sealingly connected through the first sealing member. The cold air sucked from the gas pump can change direction through the adapter and then enter the inner cavity of the pot body through the pipe body. The pipe assembly further comprises a second sealing member. When the pipe body is plugged into the plug-in port, the sealing lip of the second sealing member abuts and seals with the steam valve, so as to sealingly connect the pipe assembly with the steam valve, and prevent the outside cold air or the steam in the inner cavity of the pot body from entering the inside of the cover assembly through the gap between them.
[0024] 4. The cover plate is detachably mounted on the cover, when the cover plate is mounted on the cover, the pipe assembly is inserted into the insertion port, so as to realize the cold air into the cavity of the pot body by using the air pump and the pipe assembly, so as to achieve the purpose of breaking the bubble and preventing the overflow; when the cover plate is detached from the cover, the pipe assembly is extracted from the insertion port, so as to realize the cover plate and the steam valve on the cover plate are detached from the cover for cleaning.
[0025] 5. By forming the installation track on the cover, the air pipe connected with the air pump and the pipe assembly is installed on the installation track, so that the air pipe is not easy to bend, and the air is more smooth. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION
[0042] In order to enable a person skilled in the art to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0043] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the description are only some of the embodiments of the present application, not all the embodiments.
[0044] Referring to Figures 1 to 13 Some embodiments of the present application provide a cover assembly of a cooking utensil, which can be covered on a pot body assembly of the cooking utensil. Specifically, the pot body assembly has a pot body cavity for containing food materials, and the cover assembly is arranged openable and closable relative to the pot body assembly, so as to cover the cover assembly at the opening of the pot body cavity during cooking, to keep the pot body cavity warm and pressurized, and to improve the cooking efficiency.
[0045] Referring to Figures 1 to 3As shown, the cover assembly of the cooking utensil provided by some embodiments of the present application comprises a cover 1 and a cover plate 2. The cover plate 2 is installed on the cover 1, and the cover plate 2 is provided with a steam valve 3. The steam valve 3 has a steam inlet 31 which is in communication with the inner cavity of the pot body of the cooking utensil, and a steam outlet 32 which is in communication with the outside. The steam generated in the cooking process can enter the steam valve 3 through the steam inlet 31, and finally be discharged through the steam outlet 32 of the steam valve 3. During the cooking process, when the food in the pot body continuously boils, foam will be generated, and there is a problem that the foam will overflow through the steam outlet 32 of the steam valve 3.
[0046] Based on this, referring to Figures 1 to 3 As shown, the cover 1 is provided with an air pump 4 and a pipe assembly 5. The suction port 41 of the air pump 4 is in communication with the outside, and the exhaust port 42 of the air pump 4 is in communication with the pipe assembly 5. The steam valve 3 is formed with a plug-in port 33, and the pipe assembly 5 passes through the plug-in port 33 and forms an air inlet 50 which is in communication with the inner cavity of the pot body. In this way, during the cooking process, the air pump 4 is used to pump the cold air from the outside to the inner cavity of the pot body through the pipe assembly 5. The temperature difference between the cold air and the foam generated in the inner cavity of the pot body causes the steam in the foam to liquefy and shrink and break, thereby achieving the purpose of preventing overflow.
[0047] In addition, the pipe assembly 5 is plugged into the plug-in port 33 formed on the steam valve 3, so that the air inlet 50 formed on the pipe assembly 5 for the cold air to enter is arranged close to the steam inlet 31 of the steam valve 3 which is in communication with the cooking inner cavity. In this way, on the one hand, the distance between the cold air inlet 50 and the steam inlet 31 can be reduced, thereby shortening the distance of the cold air flowing to the steam inlet 31 through the inner surface of the cover assembly, and further reducing the amount of rice paste and other substances adhering to the inner surface of the cover assembly formed by breaking the foam during the flowing process, which is conducive to maintaining the cleanliness of the inner surface of the cover assembly. On the other hand, it can also ensure that the cold air can better mix with the foam at the steam inlet 31 to break the foam, reduce the amount of foam in the inner cavity of the pot body which has not yet mixed with the cold air and overflows from the steam outlet 32 of the steam valve 3, thereby achieving better breaking of the foam and preventing overflow.
[0048] In order to facilitate cleaning of the cover assembly of the cooking utensil, the cover plate 2 is detachably installed on the cover 1. The cover plate 2 can also be referred to as a movable cover plate 2 or a detachable cover. The cover plate 2 is generally made of metal material. Specifically, the cover plate 2 is detachably installed on the inner side of the cover 1. The cover 1 is generally made of plastic material and is used as a mounting member for some components (such as the air pump 4, the pipe assembly 5, etc.).
[0049] In some embodiments, referring to Figures 1 to 3As shown, the cover assembly of the cooking utensil further comprises a face cover 7, which is arranged on the cover 1 and usually serves as an appearance part of the cover assembly of the cooking utensil. The face cover 7 is provided with a steam outlet 71, which is arranged in correspondence with and in communication with the steam outlet 32 of the steam valve 3. The steam generated during the cooking process can enter the steam valve 3 through the steam inlet 31, and finally be discharged through the steam outlet 32 of the steam valve 3 and the steam outlet 71.
[0050] In some embodiments, referring to Figures 4 to 7 As shown, the exhaust port 42 of the air pump 4 is in communication with the pipe assembly 5 through the air pipe 6, and the cover 1 is provided with a mounting track 12, and the air pipe 6 is mounted on the mounting track 12. In this way, the air pipe 6 connecting the air pump 4 and the pipe assembly 5 is mounted on the mounting track 12, so that the air pipe 6 is not easy to bend, which not only makes the air flow smoother, but also helps to prolong the service life of the air pipe 6.
[0051] In specific implementation, the air pipe 6 can be a flexible hose, and the mounting track 12 can be an arc-shaped track. The air pipe 6 is arranged along the mounting track 12 and is limited in the mounting track 12. Specifically, the mounting track 12 can be integrally formed on the cover 1, and the mounting track 12 can specifically include a plurality of arc-shaped rib positions integrally formed on the cover 1, which together form an arc-shaped track.
[0052] In some embodiments, referring to Figures 8 to 12 As shown, the plug-in port 33 on the steam valve 3 is arranged in correspondence with and in communication with the steam inlet 31, and the pipe assembly 5 passes through the plug-in port 33 and the steam inlet 31 in sequence, so that the steam inlet 31 forms an annular steam inlet 31 around the pipe assembly 5. That is, the pipe assembly 5 is inserted into the steam inlet 31 through the plug-in port 33 on the steam valve 3.
[0053] By forming the steam inlet 31 into an annular steam inlet 31 around the pipe assembly 5, the cold air inlet 50 and the annular steam inlet 31 are located at the same position. During the cooking process, the steam in the inner cavity of the pot body enters the steam valve 3 through the annular steam inlet 31 and is finally discharged from the steam outlet 32 of the steam valve 3. The external cold air enters the inner cavity of the pot body through the air inlet 50 of the pipe assembly 5 located at the annular steam inlet 31. The annular steam inlet 31 can increase the contact area between the steam and the pipe wall of the pipe assembly 5. Since the pipe assembly 5 is filled with cold air with relatively low temperature, the steam will break when it contacts with the pipe wall with relatively low temperature, thereby increasing the probability of breaking. In addition, the cold air in the pipe assembly 5 will continuously lower the temperature of the annular steam inlet 31 through the pipe wall of the pipe assembly 5, thereby increasing the probability of breaking of the steam flowing through the annular steam inlet 31, and further achieving better breaking and anti-overflow effect.
[0054] In addition, by forming the steam inlet 31 as a ring-shaped steam inlet 31 surrounding the pipe assembly 5, the cold air entering the inner cavity of the pot body can be evenly dispersed in all directions, so as to better contact the hot foam in the inner cavity of the pot body, and the air cooling and defoaming effect is better.
[0055] Referring to Figure 13 As shown in the figure, the dashed arrows in the figure show the flow direction of the cold air. After the cold air enters the inner cavity of the pot body through the pipe assembly 5, due to the ring-shaped steam inlet 31 formed around the pipe assembly 5, the cold air in the inner cavity of the pot body can be evenly dispersed in all directions. After contacting the hot foam in the inner cavity of the pot body and defoaming, the cold air enters the steam valve 3 through the ring-shaped steam inlet 31 around the pipe assembly 5, and finally is discharged through the steam outlet 71 on the cover 7 after passing through the steam outlet 32 of the steam valve 3.
[0056] In addition, by forming the steam inlet 31 as a ring-shaped steam inlet 31 surrounding the pipe assembly 5, the cold air inlet 50 and the ring-shaped steam inlet 31 are arranged at the same position, so that the distance between the cold air inlet 50 and the ring-shaped steam inlet 31 is as close as possible. In this way, the steam flow in other horizontal areas can be reduced, so that the rice paste is not easy to adhere to the inner surface of the cover assembly, thereby improving the cleanliness of the cover assembly in use. Specifically, if the distance between the cold air inlet 50 and the steam inlet 31 is far, the cold air needs to pass a certain path on the inner surface of the cover assembly to reach the steam inlet 31, thereby forming a cold and hot alternating layer on the inner surface of the cover assembly and being thin, which is easy to cause the rice paste to adhere, and affects the cleanliness of the cover assembly in use.
[0057] In addition, after the cold air defoaming, the pressure in the inner cavity of the pot body is reduced, and the total amount of bubbles in the inner cavity of the pot body is reduced, so that the rice paste is not easy to adhere to the inner surface of the cover assembly, which is beneficial to ensure the cleanliness of the cover assembly in use.
[0058] In specific implementation, in order to ensure the steam discharge effect, the steam inlet 31 of the steam valve 3 is formed with a steam inlet passage extending upward; the pipe assembly 5 includes a pipe body 52, which can be a metal pipe such as a steel pipe, or other hard pipes such as hard plastic pipes, etc.; the pipe body 52 is inserted into the steam inlet 31 through the plug-in port 33 of the steam valve 3. Specifically, the inner circumferential region of the pipe body 52 forms an air inlet passage for cold air to enter, the lower pipe opening of the pipe body 52 is formed as a cold air inlet 50 communicating with the inner cavity of the pot body, and the outer circumferential region of the pipe body 52 and the inner wall surface of the steam inlet passage form a steam passage for steam to enter. In this way, the heat exchange efficiency between the cold air in the pipe body 52 and the steam in the outer periphery can also be increased, thereby better improving the defoaming effect.
[0059] To avoid the condensation of water on the inner surface of the cover assembly after cooking to affect the taste of the food in the inner cavity of the pot, in some embodiments, a heating pipe or other heating element is arranged on the side of the cover 1 facing the cover plate 2. By arranging the pipe assembly 5 at the steam inlet 31 of the steam valve 3, the pipe assembly 5 does not need to occupy additional space on the cover 1, so as to arrange a larger area of heating pipe on the cover 1, thereby improving the top heating effect.
[0060] In some embodiments, referring to Figure 2 and Figure 3 , Figure 9 and Figure 10 , the pipe assembly 5 passes through the steam inlet 31 and protrudes from the end face of the steam inlet 31. That is, the lower end face of the air inlet 50 formed on the pipe assembly 5 is arranged lower than the lower end face of the steam inlet 31. In this way, it can be ensured that the external cold air enters the inner cavity of the pot through the pipe assembly 5, so as to better contact with the steam in the inner cavity of the pot, thereby achieving good bubble breaking and anti-overflow effect.
[0061] In some embodiments, referring to Figures 8 to 10 , the steam valve 3 includes a valve seat 34 and a valve cover 35, and the valve cover 35 covers the valve seat 34; the steam inlet 31 is formed on the valve seat 34, and the steam outlet 32 and the insertion port 33 are formed on the valve cover 35.
[0062] In this way, the valve cover 35 is arranged on the valve seat 34 to form a steam chamber between the valve cover 35 and the valve seat 34, so that the steam in the inner cavity of the pot enters the steam chamber formed on the steam valve 3 through the steam inlet 31, and then is discharged through the steam outlet 32. Specifically, the steam inlet 31 can be arranged in correspondence with and in communication with the insertion port 33, so that the pipe assembly 5 can be inserted into the steam inlet 31 through the insertion port 33; the steam inlet 31 can be arranged staggered with the steam outlet 32 to increase the flow path of the steam in the steam valve 3, thereby improving the bubble breaking and anti-overflow effect; the steam outlet 32 is arranged in correspondence with and in communication with the steam discharge port 71 on the cover plate 7, and a sealing ring 36 is arranged at the steam outlet 32 to ensure the sealing between the steam outlet 32 and the cover plate 7.
[0063] In specific implementation, the valve cover 35 and the valve seat 34 can be detachably connected, so as to detach the valve cover 35 from the valve seat 34 to clean the inside of the steam valve 3. In addition, the valve seat 34 of the steam valve 3 can be fixed on the cover plate 2, and specifically can be detachably connected with the cover plate 2, so as to detach the steam valve 3 from the cover plate 2 to thoroughly clean the steam valve 3 and the cover plate 2.
[0064] It should be noted that the pipe assembly 5 is not limited to being installed at the steam inlet 31. In other words, the insertion port 33 on the steam valve 3 is not limited to being corresponding to and connected to the steam inlet 31.
[0065] In other embodiments, the insertion port 33 on the steam valve 3 is offset from the steam inlet 31. That is, the insertion port 33 and the steam inlet 31 are not located in the same vertical direction. The pipe assembly 5 passes through the insertion port 33 and communicates with the inner cavity of the pot, so that the cold air inlet 50 formed on the pipe assembly 5 is offset from the steam inlet 31. In this way, the cold air inlet 50 and the steam inlet 31 can also be set close to each other, thereby effectively ensuring the defoaming and anti-overflow effects, and reducing the adhesion of rice paste and other substances to the inner surface of the lid assembly.
[0066] In some embodiments, refer to Figure 4 , Figure 5 , Figures 8 to 10 As shown, the pipe assembly 5 includes an adapter 51, a pipe body 52, and a first seal 53; wherein, the adapter 51 includes a first adapter interface and a second adapter interface that are interconnected, the air pump 4 is connected to the first adapter interface through the air pipe 6, one end of the pipe body 52 is connected to the second adapter interface, the other end of the pipe body 52 passes through the insertion port 33 and forms an air inlet 50 for cold air to enter, and the first seal 53 is disposed between the pipe body 52 and the second adapter interface.
[0067] This configuration allows the tube body 52 to be connected to the air pump 4 via the adapter 51, and the adapter 51 to be sealed to the tube body 52 via the first seal 53. This allows the cold air drawn in from the air pump 4 to change direction via the adapter 51 and then enter the inner cavity of the cooker via the tube body 52.
[0068] In practical implementation, the first and second interfaces of the adapter 51 can be set at a certain angle, such as a 90-degree angle, to achieve turning using the adapter 51. The pipe body 52 can be made of metal, such as steel, or other rigid pipes, such as rigid plastic pipes, to ensure that the pipe body 52 has sufficient structural strength to meet the structural strength requirements of the insertion operation.
[0069] To achieve the connection between the pipe body 52 and the adapter 51, an annular connecting piece can be provided at one end of the pipe body 52 and the adapter 51. The annular connecting piece can be welded to the outer wall of the pipe body 52. An annular groove can be provided at the second adapter interface of the adapter 51, and the annular connecting piece is installed in the annular groove. The first sealing element 53 can be a sealing gasket, which is installed in the annular groove. The annular connecting piece is pressed on the sealing gasket to achieve a sealed connection between the second adapter interface and the pipe body 52 using the sealing gasket.
[0070] In some embodiments, refer to Figure 4 andFigure 5 As shown, the adapter 51 is arranged on the side of the cover 1 away from the cover plate 2, one end of the pipe body 52 is located on the side of the cover 1 away from the cover plate 2 and connected with the second adapter interface, the cover 1 is provided with a mounting hole 11, the other end of the pipe body 52 passes through the mounting hole 11 and extends to the side of the cover 1 facing the cover plate 2. In this way, the adapter 51 and the pipe body 52 are fixedly installed on the cover 1, and the pipe body 52 is connected with the air pump 4 through the adapter 51; and after the pipe body 52 passes through the mounting hole 11 on the cover 1, it can pass through the insertion port 33 of the steam valve 3 and be inserted at the steam inlet 31 of the steam valve 3.
[0071] In some embodiments, referring to Figure 9 and Figure 10 As shown, the pipe assembly 5 further comprises a second sealing member 54; the second sealing member 54 is sleeved on the pipe body 52, the second sealing member 54 has a sealing lip 541, the pipe body 52 is inserted into the insertion port 33, and the sealing lip 541 is in abutting sealing with the steam valve 3. In this way, when the pipe body 52 is inserted into the insertion port 33, the sealing lip 541 of the second sealing member 54 is in abutting sealing with the steam valve 3, so as to realize the sealed connection between the pipe assembly 5 and the steam valve 3, and prevent the external cold air or the steam in the inner cavity of the pot body from entering the inside of the cover assembly through the gap therebetween.
[0072] In some embodiments, the cover plate 2 is detachably installed on the cover 1, so as to facilitate the dismounting of the cover plate 2 from the cover 1 for cleaning.
