[0002] In the related art, a cooking utensil may usually be provided with a steam valve on a pot cover so that the cooking utensil can use the steam valve to discharge the water vapor generated by heating and cooking the food in the pot.

[0003] The temperature and humidity of water vapor are relatively high. In order to prevent water vapor from being discharged into the environment and affecting the humidity and temperature of the indoor environment, and to prevent high-temperature steam from burning users, an air blast channel can be provided in the steam valve so that the low-temperature fluid can pass through the air blast channel to enter the steam valve and mix with the water vapor to cool it down, thereby allowing the cooking pot to discharge a small amount of steam or low-temperature steam, reducing the impact on the environment and users.

[0045] In order to prevent water vapor from being discharged into the environment and affecting the humidity and temperature of the indoor environment, and to prevent high-temperature steam from burning users, an air blast channel can be provided in the steam valve, so that the low-temperature fluid can enter the steam valve through the air blast channel to mix with the water vapor and cool it down, thereby allowing the cooking pot to discharge a small amount of steam or low-temperature steam, reducing the impact on the environment and users. When water vapor flows in the steam valve, it is easy for some water vapor to flow back into the air blast channel, making it easy for water vapor to condense when encountering the low-temperature fluid in the air blast channel, and then causing condensed water to accumulate in the air blast channel, making the components in the air blast channel easily damaged by moisture, affecting the normal operation of the cooking appliance, and reducing the structural stability and reliability of the steam valve. In view of the above problems, the utility model proposes a steam valve.

[0046] Reference Figures 1 to 8 In an embodiment of the utility model, the steam valve 100 includes a valve body 10 and a sealing member 30. A steam channel 11 and an air blast channel 13 are provided in the valve body 10. The air blast channel 13 is provided on one side of the steam channel 11 and is provided with an air outlet 131 connected to the steam channel 11. The sealing member 30 is movably provided in the valve body 10 to open or close the air outlet 131.

[0047] It is understandable that the cooking utensil may be an electric rice cooker, a pressure cooker or a steamer, etc. The cooking utensil may generally include a pot body for heating and cooking the food and a pot cover 1000 for covering the pot body to form a closed cooking utensil, so that the cooking utensil can stably and reliably complete the cooking operation on the food and meet the user's use needs. In the process of heating the food in the pot body, when the water in the food is heated to a certain temperature, water vapor will be generated and filled in the pot body, so that the air pressure in the pot body gradually increases with the increase of water vapor. At this time, when the cooking utensil is a pressure cooker, the effect of pressurized cooking can be achieved by increasing the pressure in the pot. A steam valve 100 can usually be provided on the pot cover 1000, and the steam inlet 113 of the steam valve 100 can be provided on the side of the pot cover 1000 facing the pot body, or the steam inlet 113 can be provided on a sealing pressure plate of the pot cover 1000 that seals the pot mouth of the pot body, and the sealing pressure plate is used to cover the open part of the steam valve 100 connected to the steam channel 11, so that water vapor can enter the steam channel 11 of the steam valve 100 through the steam inlet 113; then, by providing a steam outlet 115 connected to the steam channel 11 of the steam valve 100 on the surface of the pot cover 1000, or making the steam outlet 115 of the steam valve 100 exposed on the surface of the pot cover 1000, the steam valve 100 can be used to drain and discharge the water vapor generated in the pot body, so that the cooking appliance can better maintain the air pressure in the pot body within the required regulated air pressure range for cooking, thereby ensuring the stable operation of the cooking appliance.

[0048] In the present application, the valve body 10 of the steam valve 100 can be separated by a partition to form a steam channel 11 and an air blast channel 13, so that the water vapor generated in the pot body can be discharged into the environment where the cooking device is located through the steam channel 11. By arranging the air blast channel on one side of the steam channel and opening an air outlet 131 connected to the steam channel 11 on the inner side wall of the air blast channel, a low-temperature airflow with a relatively low temperature can be introduced into the air blast channel 13, so that the low-temperature airflow flows from the air blast channel 13 through the air outlet 131 into the steam channel 11, so that the low-temperature airflow can be discharged into the steam channel 11. The steam valve 100 can cool the water vapor by mixing with the high-temperature water vapor in the steam channel 11, thereby reducing the temperature of the water vapor discharged through the steam outlet 115 of the steam valve 100, or can reduce the temperature of most of the water vapor in the steam valve 100, so that the amount of water vapor discharged by the steam valve 100 is reduced, and the low-temperature steam discharge or trace steam discharge of the cooking appliance is realized, which is conducive to better reducing the impact of the high-temperature and high-humidity water vapor discharged by the cooking appliance on the indoor environment and users, and improving the practicality and reliability of the steam valve 100. Among them, by setting the blast channel 13 on one side of the steam channel 11, and setting the air outlet 131 between the blast channel 13 and the inner side wall of the steam channel 11, the low-temperature airflow flowing in the blast channel 13 can be diffused in the steam channel 11 through the air outlet 131, and the water vapor rising and spreading in the steam channel 11 can be cooled and cooled by the low-temperature airflow diffused laterally in the steam channel 11, which effectively improves the cooling effect of the steam valve 100 on the water vapor. By arranging air outlet holes 131 on the inner side walls of the air blast channel 13 and the steam channel 11, it is also possible to prevent the water vapor rising in the steam channel 11 from flowing toward the air outlet holes 131 and entering the air blast channel 13, thereby helping to better reduce the condensation of water vapor in the air blast channel 13 to produce condensed water, avoid damage to the components of the air blast channel 13 due to moisture, and further improve the structural stability and reliability of the steam valve 100.

[0049] By setting a movable sealing member 30 in the steam valve 100, the sealing member 30 may be a plug body or a valve structure arranged near the air outlet 131. By utilizing the movement of the sealing member 30 in the valve body 10, the sealing member 30 can be made to block or cover the air outlet 131 in the valve body 10 to close the air outlet 131, or can be moved to one side of the air outlet 131 to open the air outlet 131. Therefore, by arranging a seal 30 in the valve body 10 to control the opening and closing of the air outlet 131, during the cooking process, the seal 30 can first be moved toward the air outlet 131 to stably close the air outlet 131 and separate the blast channel 13 from the steam channel 11, and then a low-temperature airflow is stably introduced into the blast channel 13 and then the seal 30 is moved away from the air outlet 131 to open the air outlet 131, so that the low-temperature airflow can stably enter the steam channel 11 to cool the water vapor. At this time, since the low-temperature airflow continues to flow through the air outlet 131, the water vapor at the air outlet 131 that has a tendency to enter the blast channel 13 can be expelled, and the water vapor can be prevented from flowing back into the blast channel 13. When it is necessary to stop the cooling and condensation of water vapor, the low-temperature airflow can be maintained to flow in the air blast channel 13 and the steam channel 11, and the seal 30 can be moved toward the air outlet 131 to close the air outlet 131. After the seal 30 stably closes the air outlet 131 to separate the air blast channel 13 and the steam channel 11, the low-temperature airflow into the air blast channel 13 is stopped. This can effectively prevent water vapor from flowing back into the air blast channel 13 when the low-temperature airflow is turned on and off in the air blast channel 13 to form condensed water and accumulate in the air blast channel 13, which is beneficial to avoiding damage to components in the air blast channel 13 due to moisture, reducing the maintenance and overhaul times of the steam valve 100, ensuring the stable operation of the steam valve 100, and improving the overall structural stability and reliability of the steam valve 100.

[0050] In addition, when the steam valve 100 is applied to cooking appliances such as electric rice cookers, when the cooking appliance is running to the boiling stage of the food in the pot, the low-temperature airflow introduced into the blast channel 13 can enter the steam channel 11 and spread to the pot body to cool down and break the foam generated in the pot body, so that the cooking appliance can achieve a better cooking effect. At this time, after the bubble breaking process is completed, the low-temperature airflow is stopped from entering the blast channel 13 after closing the air outlet 131 with the seal 30, which can effectively prevent the boiling rice soup that has entered the steam channel 11 from flowing back into the blast channel 13, further prevent the accumulation of liquid in the blast channel 13, ensure the normal operation of each component in the blast channel 13, and further improve the structural stability and reliability of the steam valve 100.

[0051] The technical solution of the utility model is to arrange a steam channel 11 and an air blast channel 13 in the valve body 10, and the air blast channel 13 is arranged on one side of the steam channel 11, and an air outlet hole connected to the steam channel 13 is arranged on the inner wall of the air blast channel 11, so that the low-temperature airflow flowing in the air blast channel 11 can be blown into the steam channel 13 laterally through the air outlet hole, so that the water vapor flowing upward in the steam channel 11 can be intercepted and cooled by the low-temperature airflow that quickly diffuses in the steam channel 11, thereby realizing that the steam valve 100 can stably and reliably cool down the water vapor generated in the cooking process, and reduce the effect of the high-temperature water vapor discharged by the steam valve 100 on the environment. By arranging a sealing member 30 in the valve body 10 and utilizing the sealing member 30 to move in the air blast channel 13 to open or close the air outlet 131, water vapor can be effectively prevented from flowing back into the air blast channel 13 to form condensed water and accumulate in the air blast channel 13 when the low-temperature airflow is turned on and off in the air blast channel 13. This is beneficial to preventing components in the air blast channel 13 from being damaged by moisture, reducing the number of maintenance and overhaul times of the steam valve 100, ensuring the stable operation of the steam valve 100, and improving the overall structural stability and reliability of the steam valve 100.

[0052] Reference Figures 1 to 3 In one embodiment of the present utility model, the valve body 10 is defined to have an up-down direction and a horizontal direction, the steam channel 11 is extended along the up-down direction, and the blast channel 13 is extended along the horizontal direction.

[0053] In this embodiment, from Figure 3 It can be seen that Figure 3 The figure is a flow diagram of the low-temperature airflow in the steam valve 100 entering the steam channel 11 through the air outlet 131 and mixing with the warm water vapor entering the steam channel 11 through the steam inlet 113 and flowing in the steam channel 11. By extending the steam channel 11 in the vertical direction in the valve body 10 and extending the air blast channel 13 in the horizontal direction in the valve body 10, the water vapor can flow from bottom to top in the steam channel 11, and the low-temperature airflow can enter the steam channel 11 through the air outlet 131 in the horizontal direction, so that the direction of the low-temperature airflow flowing into the steam channel 11 through the air outlet 131 can be set at an angle with the direction of the water vapor flowing in the steam channel 11. At this time, since the water vapor carries heavier water vapor molecules, the flow rate of the low-temperature airflow entering the steam channel 11 horizontally can be greater than the flow rate of the water vapor, so that the low-temperature airflow can better rush into the steam channel 11 from the side to intercept the rising water vapor and greatly reduce the temperature of the water vapor, which is beneficial to better prevent high-temperature water vapor from being discharged from the steam outlet 115 of the steam valve 100, and further improve the cooling effect of the steam valve 100 on water vapor.

[0054] Reference Figure 1 , Figure 2 and Figure 6In one embodiment of the present invention, the steam valve is further provided with a driving mechanism 50 , which is connected to the sealing member 30 and drives the sealing member 30 to move so as to open or close the air outlet 131 .

[0055] In this embodiment, a driving mechanism 50 is provided on the valve body 10 to connect with the sealing member 30. The driving mechanism 50 may be a push rod traction device or a cable traction device, etc., so that the driving mechanism 50 can be driven to move on the valve body 10, and the driving mechanism 50 is used to transmit power to the sealing member 30 to drive the sealing member 30 to move, or the driving mechanism 50 can be used to pull the sealing member 30 to rotate, so that the sealing member 30 rotates in the valve body 10 to be close to the air outlet 131 or away from the air outlet 131. Then, the sealing member 30 driven by the driving mechanism 50 moves in the blast channel 13, so that the steam valve can use the control unit to control the driving mechanism 50 to achieve stable control of the movement of the sealing member 30, and then the sealing member 30 can be opened or closed to the air outlet 131 more stably and reliably, so as to ensure the control and stable operation of the steam valve 100 in the cooking appliance, and is conducive to better use of the sealing member 30 to isolate water vapor or foam from entering the blast channel 13, and further improve the stability and reliability of the steam valve 100.

[0056] Reference Figures 1 to 6 In one embodiment of the utility model, the driving mechanism 50 includes an electromagnet 51 and a push rod structure 53, one end of the push rod structure 53 is inserted into the electromagnet 51, and the other end of the push rod structure 53 is connected to the seal 30. The electromagnet 51 drives the push rod structure 53 to telescopically move, so that the push rod structure 53 drives the seal 30 to reciprocate.

[0057] It can be understood that the driving mechanism 50 may include an electromagnet 51 and a push rod structure 53. The electromagnet 51 may be a hollow electromagnetic coil winding structure. By movably inserting the push rod structure 53 in the electromagnet 51, a permanent magnet with a certain magnetism may be arranged inside the push rod structure 53. By turning the electromagnet 51 on and off or changing the direction of current flow in the electromagnet 51, the magnetic field generated by the electromagnet 51 changes, so that the push rod structure 53 can drive the seal 30 to move under the action of the magnetic field. For example, when the magnetic field generated by the electromagnet 51 is the same as the magnetic field of the permanent magnet in the push rod structure 53, the push rod structure 53 may be subjected to the force of magnetic repulsion and move in a direction away from the electromagnet 51; or when the magnetic field generated by the electromagnet 51 is different from the magnetic field of the permanent magnet in the push rod structure 53, the push rod structure 53 may be subjected to the force of magnetic attraction and move in a direction away from the electromagnet 51. Furthermore, the push rod structure 53 can drive the seal 30 to move under the change of the magnetic field generated by the electromagnet 51, thereby ensuring that the seal 30 can open and close the air outlet 131 under the stable driving action of the driving mechanism 50, further improving the structural stability and reliability of the steam valve 100.

[0058] Furthermore, the push rod structure 53 includes an electromagnetic push rod 531 and a traction rod 533. One end of the electromagnetic push rod 531 is movably inserted into the electromagnet 51. One end of the traction rod 533 is connected to the electromagnetic push rod 531, and the other end of the traction rod 533 is connected to the seal 30. The electromagnet 51 drives the electromagnetic push rod 531 to telescope and move, so that the electromagnetic push rod 531 drives the traction rod 533 and the seal 30 to move back and forth.

[0059] In this embodiment, by making the push rod structure 53 include an electromagnetic push rod 531 and a traction rod 533, a permanent magnet can be arranged in the electromagnetic push rod 531, and the electromagnetic push rod 531 is inserted in the electromagnet 51 to interact with the electromagnet 51 through magnetic attraction, and the traction rod 533 is connected to the electromagnetic push rod 531. When the electromagnetic push rod 531 moves due to the action of the electromagnet 51, the traction rod 533 is driven to move. This is conducive to making the traction rod 533 adopt a non-magnetic structure setting, reducing the magnetic field of the electromagnetic push rod 531 from being transmitted to the steam valve through the traction rod 533. At the same time, the traction rod 533 is used to extend the electromagnetic push rod 53 in sections, which is also conducive to more convenient assembly of the drive mechanism 50 in the steam valve 100, further improving the assembly convenience and practicality of the steam valve 100.

[0060] Reference Figure 5 In one embodiment of the present utility model, the driving device 51 is further provided with an elastic member 55 , which is sleeved on the electromagnetic push rod 531 and connects the electromagnet 51 and the electromagnetic push rod 531 .

[0061] In this embodiment, an elastic member 55 is provided between the electromagnet 51 and the electromagnetic push rod 531. The elastic member 55 may be a spring or a tension spring with a certain elasticity. When the electromagnet 51 drives the electromagnetic push rod 531 to move in a direction away from the electromagnet 51, the magnetic force between the electromagnetic push rod 531 and the electromagnet 51 may be used to drive the elastic member 55 to undergo elastic deformation. At this time, when it is necessary to drive the electromagnetic push rod 531 to move in a direction toward the electromagnet 51, the electromagnet 51 may be directly powered off, and then the elastic member 55 may be used to restore the elastic deformation to drive the electromagnetic push rod 531 to move in a direction toward the electromagnet 51, so that the driving device 51 may realize the movement drive of the battery push rod by the way of powering on and off the electromagnet 51, which is conducive to reducing the control of the current flow direction of the electromagnet 51, so that the steam valve 100 may realize a simpler control method, and facilitate the lightweight design of the steam valve 100.

[0062] Reference Figure 3 and Figure 5 In one embodiment of the utility model, a traction groove 5333 or a connecting boss 5311 is provided on one side of the traction rod 533, and a traction groove 5333 or a connecting boss 5311 is provided on the outer peripheral side of the electromagnetic push rod 531, and the connecting boss 5311 is clamped in the traction groove 5333.

[0063] In this embodiment, the traction rod 533 can have a traction groove 5333 on one side, and a connecting boss 5311 corresponding to the traction groove 5333 is provided on the outer periphery of the electromagnetic push rod 531. At this time, the connection boss 5311 can be used to snap into the traction groove 5333 to achieve connection between the traction rod 533 and the electromagnetic push rod 531, thereby better realizing convenient disassembly and assembly between the traction rod 533 and the drive device 51, so that the steam valve 100 can more conveniently remove the drive device 51 from the valve body 10 for inspection and maintenance, thereby ensuring the stable operation of the steam valve 100 and further improving the practicality and reliability of the steam valve 100.

[0064] Alternatively, the traction rod 533 can have a connecting boss 5311 on one side, and a traction groove 5333 corresponding to the connecting boss 5311 can be set on the outer periphery of the electromagnetic push rod 531. At this time, the connection boss 5311 can be snapped into the traction groove 5333 to achieve connection between the traction rod 533 and the electromagnetic push rod 531, thereby better realizing convenient disassembly and assembly between the traction rod 533 and the drive device 51, thereby further improving the practicality and reliability of the steam valve 100.

[0066] In this embodiment, by arranging a first magnetic component in the traction rod 533 and arranging a second magnetic component on the side of the electromagnet 51 facing the pro-Yingan, when the electromagnetic push rod 531 drives the traction rod 533 to move in the direction toward the electromagnet 51, the first magnetic component and the second magnetic component can be used to cooperate with each other by magnetic attraction so that the electromagnetic push rod 531 can better maintain the position of the sealing member 30 at this time, which is beneficial to avoid the failure of the electromagnet 51, which causes the electromagnetic push rod 531 to drive the traction rod 533 to move in the direction away from the electromagnet 51 and affect the stable operation of the steam valve 100, so that the magnetic attraction cooperation between the first magnetic component and the second magnetic component at this time can play a certain role in assisting in stabilizing the traction rod 533, and when it is necessary to drive the electromagnetic push rod 531 to move in the direction away from the electromagnet 51, the magnetic field force of the electromagnet 51 can be used to drive the electromagnetic push rod 531 to move and separate the magnetic attraction cooperation between the first magnetic component and the second magnetic component, thereby ensuring the stable opening and closing of the air outlet 131 by the sealing member 30, and further improving the structural stability and reliability of the steam valve 100. Among them, the first magnetic part can be a permanent magnet with a certain magnetism, and the second magnetic part can be a permanent magnet or a magnetized metal with opposite magnetism to the first magnetic part; or, the first magnetic part can be a magnetized metal, and the second magnetic part can be a permanent magnet with a certain magnetism.

[0067] Reference Figures 3 to 5 In one embodiment of the utility model, the valve body 10 is provided with a limiting groove 15, and the traction rod 533 is movably arranged in the limiting groove 15. The outer peripheral side of the traction rod 533 is provided with a limiting boss 5331, and the limiting boss 5331 abuts against two opposite inner walls of the limiting groove 15.

[0068] In this embodiment, by setting a limit groove 15 in the valve body 10 and setting a limit boss 5331 on the outer periphery of the traction rod 533, the traction rod 533 can be set to move in the limit groove 15, and the limit boss 5331 can be abutted against the inner wall of the limit groove 15, and then the limit guide of the limit boss 5331 and the inner wall of the limit groove 15 can be used to better prevent the traction rod 533 from deviating in the valve body 10, so that the traction rod 533 can move in a straight line in the valve body 10 along the direction parallel to the inner wall of the limit groove 15, and then it is helpful to more stably drive the traction rod 533 to drive the seal 30 to move vertically to open or close the air outlet 131, thereby ensuring the stable operation of the steam valve 100 and further improving the structural stability and reliability of the steam valve 100.

[0069] Reference Figure 3 and Figure 4 In one embodiment of the utility model, the top view of the valve body 10 is defined as having a front-to-back direction, the steam channel 11 and the blast channel 13 are arranged side by side along the front-to-back direction, and the drive mechanism 50 is arranged on one side of the blast channel 13.

[0070] In this embodiment, on the top view of the valve body 10, the steam channel 11 and the blast channel 13 can be arranged side by side in sequence along the front-to-back direction. This layout design can make the internal space arrangement of the valve body 10 more compact, so that the low-temperature airflow in the blast channel 13 can be supplied to the steam channel 11 more quickly, thereby achieving a better cooling effect of the steam valve 100 on water vapor, and is conducive to better reducing the overall volume of the valve body 10, realizing the miniaturized design of the steam valve 100, and further helping to better reduce the overall thickness of the pot cover 1000, further improving the usability and reliability of the steam valve 100.

[0071] Further, in an embodiment of the present invention, the steam channel 11, the air blowing channel 13 and the driving mechanism 50 are sequentially arranged side by side along the front-to-back direction.

[0072] In this embodiment, by arranging the steam channel 11, the blower channel 13 and the driving mechanism 50 in parallel in the front-to-back direction, it is beneficial to realize the flow of low-temperature airflow in the blower channel 13 to the steam channel 11 in the front-to-back direction, and at the same time, the sealing member 30 can be moved in the front-to-back direction to realize the opening and closing of the air outlet 131, thereby realizing a more compact and reliable arrangement of components in the steam valve 100, which is beneficial to better ensure the rapid and reliable cooling of water vapor by the low-temperature airflow in the steam valve 100, and at the same time better reduce the overall volume of the steam valve 100, further improving the practicality and reliability of the steam valve 100.

[0073] Reference Figure 3 and Figure 4 In one embodiment of the present invention, an elastic sealing ring 31 is provided at one end of the sealing member 30 facing the air outlet 131 , and the elastic sealing ring 31 is used to abut against the inner wall of the air blast channel 13 and cover the air outlet 131 .

[0074] In the present embodiment, the seal 30 may be a plug structure that moves along the central axis direction of the air outlet hole 131. At this time, an elastic sealing ring 31 may be provided at one end of the seal 30 that faces the air outlet hole 131. The outer diameter of the elastic sealing ring 31 may be larger than the aperture of the air outlet hole 131. When the seal 30 is driven by the driving mechanism 50 to move in the direction toward the air outlet hole 131 to close the air outlet hole 131, the elastic sealing ring 31 may be used to abut against the inner wall of the valve body 10 and make the end face of the seal 30 cover the air outlet hole 131. At this time, under the action of the driving mechanism 50, the elastic sealing ring 31 may be made to abut against the inner wall of the valve body 10 by interference fit, and then the elastic sealing ring 31 may be effectively used to surround the cover air outlet hole 131, thereby improving the airtight effect between the seal 30 and the inner wall of the air blast channel 13, so that the seal 30 may close the air outlet hole 131 more stably and reliably, thereby ensuring the stable operation of the steam valve 100 and further improving the practicality and reliability of the steam valve 100.

[0075] Reference Figure 3 and Figure 4 In one embodiment of the present invention, the deformation of the elastic sealing ring 31 abutting against the inner wall of the blast channel 13 is defined as W, 0.3mm≤W≤3mm. And / or, the distance between the elastic sealing ring 31 and the air outlet 131 is defined as H, 1mm≤H≤50mm.

[0076] In the present embodiment, the elastic sealing ring 31 and the inner wall of the air blast channel 13 are connected by interference fit. When the elastic sealing ring 31 abuts against the inner wall of the air blast channel 13 to allow the seal 30 to close the air outlet hole 131, the elastic sealing ring 31 abuts against the inner wall of the air blast channel 13 and the amount of elastic deformation is between 0.3 mm and 3 mm. Within this range, the elastic deformation of the elastic sealing ring 31 can be better utilized in cooperation with the inner wall of the air blast channel 13 to form a good airtight effect, so that the seal 30 can close the air outlet hole 131 more stably and reliably. By making the elastic seal 30 abut against the inner wall of the blast channel 13 and causing elastic deformation with a deformation amount W greater than or equal to 0.3 mm, the elastic sealing ring 31 and the inner wall of the valve body 10 can have sufficient contact area to achieve a better airtight effect; at the same time, making the elastic seal 30 abut against the inner wall of the blast channel 13 and causing elastic deformation with a deformation amount W less than or equal to 3 mm can help avoid excessive deformation of the elastic sealing ring 31, which may cause damage to the elastic sealing ring 31, further ensure the stable closure of the air outlet 131 by the seal 30, prevent water vapor from flowing back into the blast channel 13, and improve the structural stability and reliability of the steam valve 100.

[0077] Secondly, the distance between the end face of the elastic sealing ring 31 and the inner wall of the air blast channel 13 where the air outlet hole 131 is located can be defined as the moving distance of the seal 30 in the air blast channel 13. By setting the distance between the elastic sealing ring 31 and the air outlet hole 131 between 1 mm and 50 mm, within this range, the seal 30 can achieve the effect of opening and closing the air outlet hole 131 more quickly, thereby ensuring the stable operation of the steam valve 100. By making the spacing W between the elastic sealing ring 31 and the air outlet 131 greater than or equal to 1 mm, it can be ensured that there is a certain gap between the seal 30 and the air outlet 131, so that the low-temperature airflow can maintain a certain flow rate and flow steadily through the air outlet 131 into the steam channel 11 to cool the water vapor, thereby ensuring the stable operation of the steam valve 100; at the same time, making the spacing W between the elastic sealing ring 31 and the air outlet 131 less than or equal to 50 mm is beneficial to preventing the moving path of the seal 30 in the blast channel 13 from being too large, so that the seal 30 can move more quickly in the blast channel 13 to open or close the air outlet 131, thereby avoiding the seal 30 from moving too large and failing to cooperate well in closing the air outlet 131 when the seal 30 fails, thereby improving the structural stability and reliability of the steam valve 100. Preferably, the spacing between the elastic sealing ring 31 and the air outlet 131 can be set between 5 mm and 10 mm. Within this range, the seal 30 can have a certain moving path and the moving path is not too large, so that the seal 30 can open or close the air outlet 131 more quickly, and the air flow can more stably pass through the gap between the seal 30 and the air outlet 131, flow through the air outlet 131 and enter the steam channel 11 to cool the water vapor, further improving the structural stability and reliability of the steam valve 100.

[0078] Reference Figures 2 to 4 In one embodiment of the utility model, the valve body 10 is provided with a mounting hole 151 penetrating to the inner wall of the air blast channel 13, and the mounting hole 151 is arranged opposite to the air outlet hole 131. The sealing member 30 is movably arranged in the air blast channel 13, and the sealing member 30 is provided with a sealing sleeve 33, one end of the sealing sleeve 33 is connected to the outer periphery of the sealing member 30, and the other end of the sealing sleeve 33 is clamped in the mounting hole 151.

[0079] In this embodiment, by providing a mounting hole 151 in the valve body 10 that is opposite to the air outlet hole 131, the seal 30 can be provided in the air blast channel 13 and between the air outlet hole 131 and the mounting hole 151, and then the driving mechanism 50 can be provided on one side of the valve body 10, and then the driving mechanism 50 is connected to the seal 30 through the mounting hole 151, so that the driving mechanism 50 can stably drive the seal 30 to move toward or away from the air outlet hole 131 in the air blast channel 13, thereby realizing the opening or closing of the air outlet hole 131 by the seal 30, which is conducive to making the driving mechanism 50 more convenient to connect to the seal 30 and drive the seal 30 to move, so that the steam valve 100 can achieve a simpler structural design, ensure the stable operation of the steam valve 100, and further improve the structural stability and reliability of the steam valve 100.

[0080] At this time, in order to prevent the airflow in the blast channel 13 from being diverted and discharged through the mounting hole 151, which affects the cooling effect of the low-temperature airflow in the steam valve 100, a sealing sleeve 33 can be connected around the outer periphery of the sealing member 30, and one end of the sealing sleeve 33 can be folded through the mounting hole 151 and connected to the surrounding of the mounting hole 151. The sealing sleeve 33 can be a structure with a certain elasticity or can be bent at a certain angle, so that during the movement of the sealing member 30, the sealing sleeve 33 can be bent, retracted or stretched to avoid the movement of the sealing member 30 in the blast channel 13, so that the sealing member 30 can stably close or open the air outlet 131 under the driving action of the driving mechanism 50. Under the action of the sealing sleeve 33, the gap between the mounting hole 151 and the sealing member 30 can be closed by the sealing sleeve 33, so as to prevent the low-temperature airflow in the blast channel 13 from being diverted and discharged through the mounting hole 151, and ensure that sufficient low-temperature airflow can be introduced into the steam channel 11 to cool the water vapor, further improving the structural stability and reliability of the steam valve 100.

[0081] Reference Figures 2 to 5 In one embodiment of the utility model, the valve body 10 is provided with a fixing seat 17, the fixing seat 17 covers the end of the mounting hole 151 facing away from the air outlet 131, and the fixing seat 17 is provided with an avoidance hole 171 corresponding to the mounting hole 151. The sealing sleeve 33 is provided with a fixing flange 331, the fixing flange 331 abuts against the valve body 10 around the mounting hole 151, and the fixing seat 17 presses against the side of the fixing flange 331 facing away from the mounting hole 151.

[0082] In this embodiment, the valve body 10 can be connected to a fixing seat 17 on the side where the mounting hole 151 is provided, and the surface of the fixing seat 17 is provided with an avoidance hole 171 provided at the position corresponding to the mounting hole 151, so that the driving mechanism 50 can pass through the avoidance hole 171 and the mounting hole 151 to connect to the sealing member 30, thereby driving the sealing member 30 to move in the valve body 10. At this time, by folding one end of the sealing sleeve 33 to form a fixed flange 331, the fixed flange 331 can be arranged between the outer wall of the valve body 10 and the fixing seat 17, and the fixing flange 331 can be pressed when the fixing seat 17 is connected to the valve body 10, thereby stably achieving the connection and fixation of the sealing sleeve 33 on the valve body 10, ensuring the sealing effect of the sealing sleeve 33 on the mounting hole 151, and further improving the structural stability and reliability of the steam valve 100.

[0083] In addition, the inner wall of the avoidance hole 171 can have a certain inclination angle, and the inner diameter of the avoidance hole 171 can gradually increase in the direction away from the seal 30. At this time, by providing a protruding structure on one side of the driving mechanism 50, the driving mechanism 50 can pass through the avoidance hole 171 to drive the seal 30 to move, so that the seal 30 closes the air outlet 131. In the process, the protruding structure is used to abut against the inner wall of the avoidance hole 171 to realize the movement limit of the driving mechanism 50, thereby avoiding the excessive force between the seal 30 and the inner wall of the valve body 10, which may damage the valve body 10, thereby better ensuring the stable operation of the steam valve 100 and further improving the structural stability and reliability of the steam valve 100.

[0084] Reference Figures 5 to 8 In one embodiment of the utility model, the pot cover 1000 includes a blast device 70, which is arranged on one side of the valve body 10 of the steam valve 100 and connected to the blast channel 13, and the blast device 70 is used to drive the air flow through the blast channel 13 and the steam channel 11. And / or, the steam channel 11 is provided with a spoiler rib, and the spoiler rib is arranged on the steam flow path of the steam channel 11. And / or, the steam valve 100 is also provided with a temperature detection mechanism, and the temperature detection mechanism is at least partially arranged in the steam channel 11, and the temperature detection mechanism is used to detect the steam temperature in the steam channel 11. And / or, the valve body 10 is also provided with an air inlet hole connected to the blast channel 13, and the area of ​​the air inlet hole is defined as A, A≥5mm 2 And / or, the channel length of the blast channel 13 is defined as L, 5mm≤L≤30mm.

[0085] In this embodiment, the pot cover 1000 can be connected to a blower device 70 on one side of the valve body 10 of the steam valve 100. The blower device 70 can be an axial flow fan or a centrifugal fan, etc., and an opening connected to the blower channel 13 is provided on one side of the valve body 10, and the air outlet end of the blower device 70 covers the opening, so that the steam valve 100 can use the blower device 70 to introduce a low-temperature airflow into the blower channel 13, so that a low-temperature airflow with a faster flow rate can be introduced into the steam valve 100 to cool down the water vapor, thereby ensuring the stable operation of the steam valve 100 and further improving the structural stability and reliability of the steam valve 100.

[0086] Furthermore, by arranging the blast device 70 and the blast channel 13 side by side in the left-right direction on the top view of the pot cover 100, the airflow generated by the blast device 70 can be better blown into the blast channel 13 in a straight line along the left-right direction, effectively ensuring the stable flow of the low-temperature airflow in the blast channel 13, so that the low-temperature airflow can be more stably blown into the steam channel 11 to cool the water vapor, and ensure the cooling effect of the steam valve 100 on the water vapor. In addition, by arranging the blast device 70 and the blast channel 13 side by side, the layout of the blast device 13 and the steam valve 100 can be made more compact, reducing the laying of the pipeline in the pot cover 1000, better reducing the space occupied by the components in the pot cover 1000, which is conducive to further reducing the overall thickness of the pot cover 1000 and better realizing the miniaturization design of the cooking appliance.

[0087] Secondly, a spoiler rib can be connected to the inner wall of the steam channel 11, and the spoiler rib can be set on the path of water vapor flowing in the steam channel 11, so that the water vapor can be blocked by the spoiler rib during the flow of the water vapor in the steam channel 11, and the path of the water vapor flowing in the steam valve 100 is extended, so that the water vapor can be more fully mixed with the low-temperature airflow in the steam valve 100 to achieve cooling, ensure the stable operation of the steam valve 100, and further improve the structural stability and reliability of the steam valve 100. Among them, the flow path of the water vapor in the steam valve 100 can be further extended by arranging a plurality of spoiler ribs at a certain interval along the flow path of the water vapor in the steam channel 11, so as to achieve sufficient condensation and cooling of the water vapor in the steam valve 100, and ensure the practicality and reliability of the steam valve 100.

[0088] A temperature detection mechanism may be provided in the steam passage 11 of the steam valve 100. The temperature detection mechanism may be a thermometer or a temperature sensor, etc. The temperature detection mechanism may be used to monitor the steam temperature in the steam passage 11 in real time, so that the sealing member 30 may be fed back to determine whether the air outlet 131 is normally opened or closed according to the temperature in the steam passage 11. In the process of introducing low-temperature airflow into the steam valve 100 to condense and cool the water vapor, if the temperature in the steam passage 11 detected by the temperature detection mechanism is greater than or equal to the temperature of the water vapor, it may indicate that the low-temperature airflow has not properly entered the steam passage 11 to condense and cool the water vapor. At this time, it may be fed back that the sealing member 30 has not properly opened the air outlet 131, and the user may be warned that the steam valve 100 is faulty. Among them, one end of the temperature detection mechanism may be exposed on the side of the steam valve 100 facing the pot body, so that the temperature detection mechanism may also be used to detect the temperature in the pot body during the cooking process of the cooking utensil, thereby making the components of the cooking utensil more compact and further improving the practicality and reliability of the cooking utensil.

[0089] In addition, by setting the area A of the air inlet hole on the valve body 10 to be greater than or equal to 5 cm 2 Within the range of , the steam valve 100 can have a larger air inlet area to ensure that a sufficient amount of low-temperature airflow can be introduced into the blast channel 13 to cool the water vapor, thereby ensuring the stable operation of the steam valve 100 and further improving the structural stability and reliability of the steam valve 100.

[0090] By setting the channel length L of the blast channel 13 between 5 mm and 30 mm, within this range, the valve body 10 can better achieve a compact structural design and layout of components. By setting the channel length L of the blast channel 13 to be greater than or equal to 5 mm, a certain space can be provided in the blast channel 13 to set the seal 30, which is conducive to better conveying the low-temperature airflow to the steam channel 11 through the blast channel 13 to cool the water vapor; at the same time, by setting the channel length L of the blast channel 13 to be less than or equal to 30 mm, within this range, the channel length of the blast channel 13 will not be too long, which is conducive to better reducing the occupied space of the valve body 10, so that the steam valve 100 can be better arranged in the central area of ​​the pot cover 1000, so that the water vapor generated in the pot body can flow into the steam valve 100 more quickly through the steam inlet 113, further improving the practicality and reliability of the steam valve 100.
