[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0043] In the existing steam valve, in order to avoid the direct discharge of high-temperature and high-humidity water vapor that affects the temperature and humidity of the indoor environment, an air blast channel can be provided in the steam valve to cool the water vapor entering the steam valve, so that the cooking pot can discharge a small amount of steam or low-temperature steam, reducing the impact on the environment and users. However, during the flow of water vapor in the steam valve, some of the water vapor is likely to flow back into the air blast channel, causing the water vapor to condense in the air blast channel and accumulate in the air blast channel, which in turn causes the components in the air blast channel to be 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.

[0044] Reference Figures 1 to 8In an embodiment of the utility model, the steam valve 100 includes a valve body 10, a sealing structure 30 and a magnetic attraction mechanism 50. A steam channel 11 and an air blast channel 13 are formed in the valve body 10. An air outlet 131 connecting the steam channel 11 and the air blast channel 13 is provided in the valve body 10; the sealing structure 30 is movably arranged in the valve body 10, and a first magnetic member 311 is provided in the sealing structure 30; the magnetic attraction mechanism 50 is arranged in the valve body 10, and the magnetic attraction mechanism 50 cooperates with the sealing structure 30 by magnetic attraction, and drives the sealing structure 30 to move, so as to open or close the air outlet 131.

[0045] 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.

[0046] In the steam valve 100, a partition can be used to separate the steam channel 11 and the blast channel 13. The steam channel 11 is connected to the steam inlet 113 and the steam outlet 115 on the steam valve 100, so that the water vapor generated in the pot can be discharged into the environment where the cooking device is located through the steam channel 11; an air outlet 131 connecting the steam channel 11 and the blast channel 13 can be opened on the partition separating the steam channel 11 and the blast channel 13. At this time, by passing a low-temperature airflow into the blast channel 13, the low-temperature airflow can flow from the blast channel 13 through the air outlet 131 into the steam valve 100. In the steam channel 11, the low-temperature air flow can be mixed with the high-temperature water vapor in the steam channel 11, so that the steam valve 100 can cool the water vapor, thereby reducing the temperature of the water vapor discharged through the steam outlet 115 of the steam valve 100, or most of the water vapor can be cooled and condensed in the steam valve 100, so that the amount of water vapor discharged by the steam valve 100 is reduced, and low-temperature steam emission or trace steam emission of the cooking appliance is achieved, which is conducive to better reducing the impact of high-temperature and high-humidity water vapor emitted by the cooking appliance on the indoor environment and users, and improving the practicality and reliability of the steam valve 100.

[0047] In the present application, a sealing structure 30 is provided near the position where the air outlet 131 is provided in the valve body 10, and the sealing structure 30 can be moved in the valve body 10 to cover the air outlet 131 to close the air outlet 131, so that the air blast channel 13 and the steam channel 11 can be separated under the action of the sealing structure 30 closing the air outlet 131; or the sealing structure 30 can be moved to one side of the air outlet 131 to open the air outlet 131, thereby ensuring that the low-temperature airflow can stably flow into the steam channel 11 through the air outlet 131 to cool the water vapor. By setting a first magnetic part 311 on the sealing structure 30, the first magnetic part 311 can be a permanent magnet with a certain magnetism or a metal magnet that can be magnetically attracted, and a magnetic attraction mechanism 50 is set on the valve body 10 corresponding to the sealing structure 30. The magnetic attraction mechanism 50 can be used to generate a magnetic field to cooperate with the first magnetic part 311 for magnetic attraction, so that the sealing structure 30 can be driven to move in the valve body 10 by the force of the magnetic field generated by the magnetic attraction mechanism 50, or the magnetic attraction mechanism 50 can be moved on the valve body 10 to drive the sealing structure 30 to move in the valve body 10 following the magnetic attraction mechanism 50, so that the sealing structure 30 can be stably moved in the valve body 10 to realize the opening or closing of the air outlet 131, thereby ensuring the stable operation of the steam valve 100.

[0048] Therefore, under the control of the magnetic attraction mechanism 50 on the movement of the sealing structure 30 in the valve body 10, the sealing structure 30 can be used to open and close the air outlet 131 to control the water vapor discharged from the cooking utensil. For example, during the cooking process, the magnetic attraction mechanism 50 can be used to first drive the sealing structure 30 to move toward the air outlet 131 to stably close the air outlet 131, so that the blast channel 13 and the steam channel 11 are separated under the action of the sealing structure 30, and then the low-temperature airflow is stably introduced into the blast channel 13, and then the magnetic attraction mechanism 50 is controlled to drive the sealing structure 30 to move 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, and because the low-temperature airflow continues to flow through the air outlet 131 at this time, it can well prevent the water vapor from flowing back into the blast channel 13. When it is necessary to stop cooling and condensing the water vapor, the low-temperature airflow can be kept flowing in the blast channel 13 and the steam channel 11 first, and then the magnetic attraction mechanism 50 can be used to drive the sealing structure 30 to move toward the air outlet 131 to close the air outlet 131. After the sealing structure 30 stably closes the air outlet 131 to separate the blast channel 13 and the steam channel 11, the low-temperature airflow can be stopped from entering the blast channel 13. Then, by using the movement of the sealing structure 30 in the valve body 10 to open or close the air outlet 131, the control of the air outlet cooling water vapor in the steam valve 100 can be achieved, which is conducive to preventing the water vapor from flowing back into the blast channel 13 when the low-temperature airflow is turned on and off in the blast channel 13 to form condensed water and accumulate in the blast channel 13, avoiding the components in the blast channel 13 from being damaged by 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.

[0049] Among them, since it is necessary to maintain the low-temperature airflow in the blast channel 13 to flow stably during the operation of the steam valve 100, and then make the sealing structure 30 move against the force of the airflow to open and close the air outlet 131. By using the magnetic attraction mechanism 50 to drive the sealing structure 30 to move in the valve body 10 and then close or open the air outlet 131, the sealing structure 30 can have sufficient power to support the movement to overcome the force of the airflow, and realize the stable movement of the sealing structure 30 in the valve body 10 and then open or close the air outlet 131, which is conducive to better ensuring the stable opening and closing of the air outlet 131 in the steam valve 100, and at the same time avoiding the linkage between the low-temperature airflow in the blast channel 13 and the sealing structure 30, which causes the flow rate of the low-temperature airflow in the steam valve 100 to decrease, and further improves the practicality and reliability of the steam valve 100. The magnetic attraction mechanism 50 is used to cooperate with the sealing structure 30 to magnetically drive the sealing structure 30 to move in the valve body 10. The corresponding movement of the sealing structure 30 in the valve body 10 can also be achieved by moving the magnetic attraction mechanism 50 on the outside of the valve body 10 or controlling the on and off of the magnetic field of the magnetic attraction mechanism 50. This is conducive to more conveniently realizing the movement of the sealing structure 30 in the valve body 10, reducing the need for corresponding airtight structures when the magnetic attraction mechanism 50 is set in the valve body 10, facilitating the production and disassembly of the steam valve 100, and further improving the practicality 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 in operation and the food in the pot body is boiling, the low-temperature airflow introduced through the blast channel 13 can enter the steam channel 11 and flow back into the pot body through the steam valve 100 or the steam inlet 113 on the pot cover 1000 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 magnetic attraction mechanism 50 drives the sealing structure 30 to close the air outlet 131 and then stops the low-temperature airflow from entering the blast channel 13, which is also conducive to better preventing the boiling rice soup that has entered the steam channel 11 from flowing back into the blast channel 13, further preventing the accumulation of liquid in the blast channel 13, ensuring the normal operation of each component in the blast channel 13, and further improving the structural stability and reliability of the steam valve 100.

[0051] Reference Figures 2 to 5 In one embodiment of the utility model, the sealing structure 30 includes a movable part 31 and a sealing plug body 35. The movable part 31 is provided with a first magnetic part 311 at one end facing the magnetic attraction mechanism 50; the sealing plug body 35 is connected to the side of the movable part 31 facing the air outlet 131, and is used to open or close the air outlet 131.

[0052] In this embodiment, the sealing structure 30 can be provided with a first magnetic member 311 at one end of the movable member 31, and the sealing plug body 35 is connected to the other end of the movable member 31, and the movable member 31 is used to drive the sealing plug body 35 to move toward or away from the air outlet 131 under the action of the magnetic attraction mechanism 50, thereby realizing the opening or closing of the air outlet 131 by the sealing structure 30. At this time, by setting the magnetic attraction mechanism 50 at the position corresponding to the end of the movable member 31 on the valve body 10, the change of the production magnetic field can be realized by turning the power on and off of the magnetic attraction mechanism 50, so that the sealing structure 30 can move in the valve body 10 following the change of the magnetic field of the magnetic attraction mechanism 50; or, the magnetic attraction mechanism 50 can be used to cooperate with one end of the movable member 31 in magnetic attraction, and then the magnetic attraction mechanism 50 can be moved on the valve body 10 to drive the movable member 31 and the sealing plug body 35 to move in the valve body 10 following the moving direction of the magnetic attraction mechanism 50, thereby realizing the opening or closing of the air outlet 131, and ensuring the stable operation of the steam valve 100. By arranging a first magnetic part 311 at the end of the movable part 31, the first magnetic part 311 can be better magnetically coordinated with the magnetic attraction mechanism 50 on the valve body 10, so that the magnetic attraction mechanism 50 can more stably and reliably drive the sealing structure 30 to move in the valve body 10, further improving the structural stability and reliability of the steam valve 100.

[0053] Reference Figure 3 and Figure 4 In one embodiment of the present invention, the sealing plug body 35 is provided with an elastic sealing ring 351 , and the elastic sealing ring 351 is used to abut against the inner wall of the valve body 10 to cover the air outlet 131 .

[0054] In the present embodiment, the movable part 31 can drive the sealing plug body 35 to move along the central axis direction of the air outlet hole 131 under the action of the magnetic attraction mechanism 50. At this time, an elastic sealing ring 351 is set at one end of the sealing plug body 35 facing the air outlet hole 131. The outer diameter of the elastic sealing ring 351 can be set larger than the aperture of the air outlet hole 131. When the sealing plug body 35 moves in the direction toward the air outlet hole 131 to close the air outlet hole 131, the elastic sealing ring 351 can be used to abut against the inner wall of the valve body 10 and make the sealing plug body 35 The end face covers the air outlet 131. At this time, under the force applied by the magnetic attraction mechanism 50 to the movable part 31, the elastic sealing ring 351 can be interference fit with the inner wall of the valve body 10, and then the elastic sealing ring 351 can be effectively utilized to tightly surround the cover air outlet 131, thereby improving the airtightness between the sealing plug body 35 and the inner wall of the valve body 10, so that the sealing structure 30 can close the air outlet 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.

[0055] Reference Figure 4In one embodiment of the present utility model, the deformation amount of the elastic sealing ring 351 abutting against the inner wall of the valve body 10 is defined as W, 0.3mm≤W≤3mm.

[0056] In this embodiment, the elastic sealing ring 351 and the inner wall of the valve body 10 are connected by an interference fit. When the elastic sealing ring 351 abuts against the inner wall of the valve body 10 to allow the sealing plug body 35 to close the air outlet 131, the elastic sealing ring 351 abuts against the inner wall of the valve body 10 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 351 can be better utilized to cooperate with the inner wall of the valve body 10 to form a good airtight effect, so that the sealing structure 30 can close the air outlet 131 more stably and reliably. By making the deformation amount W of the elastic seal elastically deformed when it abuts against the inner wall of the valve body 10 greater than or equal to 0.3mm, the elastic sealing ring 351 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 deformation amount W of the elastic seal elastically deformed when it abuts against the inner wall of the valve body 10 less than or equal to 3mm is beneficial to avoid the deformation amount of the elastic sealing ring 351 being too large and causing a certain probability of damage to the elastic sealing ring 351, further ensuring the stable closure of the air outlet 131 by the sealing structure 30, preventing water vapor from backflowing into the blast channel 13, and improving the structural stability and reliability of the steam valve 100.

[0057] Reference Figure 3 In one embodiment of the present invention, the distance between the elastic sealing ring 351 and the air outlet 131 is defined as H, 1mm≤H≤50mm.

[0058] In this embodiment, the distance between the end face of the elastic sealing ring 351 and the inner wall of the valve body 10 where the air outlet 131 is located can be defined as the moving distance of the sealing structure 30 in the valve body 10. By setting the distance between the elastic sealing ring 351 and the air outlet 131 between 1 mm and 50 mm, within this range, the sealing structure 30 can achieve the effect of opening and closing the air outlet 131 more quickly, thereby ensuring the stable operation of the steam valve 100. By making the spacing W between the elastic sealing ring 351 and the air outlet 131 greater than or equal to 1 mm, it can be ensured that there is a certain gap between the sealing structure 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 351 and the air outlet 131 less than or equal to 50 mm is beneficial to preventing the moving path of the sealing structure 30 in the valve body 10 from being too large, so that the sealing structure 30 can move more quickly in the valve body 10 to open or close the air outlet 131, avoiding a large moving path of the sealing structure 30 and a certain probability that the sealing structure 30 is offset and clamped in the valve body 10 and cannot cooperate well to close the air outlet 131, thereby improving the structural stability and reliability of the steam valve 100.

[0059] Preferably, the spacing between the elastic sealing ring 351 and the air outlet 131 can be set between 5 mm and 10 mm. Within this range, the seal can have a certain moving path and the moving path is not too large, so that the seal can open or close the air outlet 131 more quickly, and the air flow can flow more stably through the gap between the seal and the air outlet 131, through the air outlet 131 and into the steam channel 11 to cool the water vapor, further improving the structural stability and reliability of the steam valve 100.

[0060] Reference Figure 3 and Figure 4 In one embodiment of the utility model, a limiting groove 133 is provided in the valve body 10, and a limiting structure 1333 is provided on the bottom wall of the limiting groove 133. Part of the movable part 31 is movably connected to the limiting structure 1333, and the limiting structure 1333 is used to guide the limiting movable part 31.

[0061] In this embodiment, the valve body 10 can be provided with a limiting groove 133 on the inner wall, so that when the sealing structure 30 opens the air outlet 131, the movable part 31 can be stored in the limiting groove 133 to avoid the flow of air, so that the low-temperature airflow in the blast channel 13 can flow through the air outlet 131 and be discharged into the steam channel 11 to cool the water vapor. At this time, by setting a limiting structure 1333 in the limiting groove 133, the limiting structure 1333 can be a limiting boss abutting the outer peripheral side of the movable part 31, or can be a guide rail on the inner wall of the limiting groove 133 that matches the outer peripheral protrusion of the movable part 31, so that the limiting structure 1333 can play a role in limiting and guiding the movement of the movable part 31, which is conducive to better preventing the sealing structure 30 from deviating during the movement in the valve body 10, so that the sealing structure 30 can open or close the air outlet 131 more stably and reliably, and further improve the structural stability and reliability of the steam valve 100.

[0062] Reference Figures 2 to 5 In one embodiment of the present utility model, the sealing structure 30 further includes an elastic member 33 , and the elastic member 33 connects the movable member 31 and the bottom wall of the limiting groove 133 .

[0063] In this embodiment, the movable part 31 and the bottom wall of the limiting groove 133 are connected by utilizing an elastic part 33. The elastic part 33 may be a spring or a metal tension spring with a certain elasticity, etc. Under the connecting action of the elastic part 33, the movable part 31 can be guaranteed to have a certain maximum moving stroke, and a certain limiting effect can be exerted on the movable part 31. In addition, the elastic member 33 can be in a state of no elastic deformation when the sealing structure 30 closes the air outlet 131, and then when the magnetic field of the magnetic attraction mechanism 50 changes and drives the sealing structure 30 to move away from the air outlet 131 to open the air outlet 131, the elastic member 33 can be elastically deformed by the force of the movable member 31 moving, causing the elastic member 33 to be compressed under the force, so that when the sealing structure 30 needs to move toward the air outlet 131 to close the air outlet 131, the magnetic attraction mechanism 50 can be directly powered off or the magnetic attraction cooperation between the magnetic attraction mechanism 50 and the sealing structure 30 can be disconnected, and then the elastic member 33 can be used to restore the elastic deformation force to drive the movable member 31 to move in the direction toward the air outlet 131 to close the air outlet 131, which is conducive to enabling the steam valve 100 to more conveniently realize the movement of the sealing structure 30 in the valve body 10, reduce the electrical control settings of the magnetic attraction mechanism 50, further simplify the overall structure of the steam valve 100, and improve the practicality and reliability of the steam valve 100.

[0064] In addition, a sealing groove 1331 can be recessed on the inner side wall of the limiting groove 133. At this time, a sealing sleeve 353 can be connected around the outer periphery of the sealing plug body 35. The sealing sleeve 353 can be a flexible ring with a certain elasticity, so that the sealing sleeve 353 can bend to avoid the movement of the movable part 31 and the sealing plug body 35 during the movement of the movable part 31. The fixed boss 3531 is folded at one end of the sealing sleeve 353 and the fixed boss 3531 is clamped in the sealing groove 1331. The sealing sleeve 353 can be used to cover the notch of the limiting groove 133 and close the movable part 31 in the limiting groove 133. This is beneficial to isolating the low-temperature airflow in the blast channel 13 from entering the limiting groove 133 under the action of the sealing sleeve 353, thereby ensuring that the low-temperature airflow can more fully flow through the air outlet 131 to act on the steam valve 100 to cool the water vapor. It is also beneficial to utilize the sealing sleeve 353 to isolate the water vapor mixed in the blast channel 13 from acting on the movable part 31 and the first magnetic part 311, thereby further improving the overall structural stability and reliability of the steam valve 100.

[0065] Reference Figure 3 and Figure 4 In one embodiment of the present invention, a second magnetic member 511 is provided on a side of the magnetic attraction mechanism 50 facing the sealing structure 30 .

[0066] In this embodiment, the magnetic attraction mechanism 50 can be provided with a second magnetic component 511 on the side facing the sealing structure 30. The second magnetic component 511 can be a permanent magnet with opposite magnetism to the first magnetic component 311, or the first magnetic component 311 can be a magnetically attractable metal and the second magnetic component 511 can be a permanent magnet. Then, by moving the second magnetic component 511 on the valve body 10, when the second magnetic component 511 is close to the sealing structure 30, the sealing structure 30 can be moved toward the second magnetic component 511 under the action of magnetic attraction. When the second magnetic component 511 is away from the sealing structure 30, the elastic force or the gravity of the sealing structure 30 itself can be used to drive the sealing structure 30 to move toward the air outlet 131 to close the air outlet 131, thereby achieving stable closing or opening of the air outlet 131 by the sealing structure 30, ensuring the stable operation of the steam valve 100, and further improving the structural stability and reliability of the steam valve 100. Among them, when the first magnetic part 311 is a permanent magnet with a certain magnetism, the magnetic attraction structure can also be arranged with a second magnetic part 511 and a third magnetic part at intervals on the side facing the sealing structure 30. The second magnetic part 511 can be a permanent magnet with opposite magnetism to the first magnetic part 311, and the third magnetic part can be a permanent magnet with the same magnetism as the first magnetic part 311. By reciprocating the magnetic attraction mechanism 50 on the valve body 10, the second magnetic part 511 and the third magnetic part can be alternately matched with the first magnetic part 311, so that the movement of the magnetic attraction mechanism 50 on the valve body 10 can be utilized to correspondingly drive the movement of the sealing structure 30 in the valve body 10, so as to realize the stable opening or closing of the air outlet 131 by the sealing structure 30.

[0067] In addition, the second magnetic part 511 can also be an electromagnetic coil structure. In this case, the first magnetic part 311 can be a permanent magnet with a certain magnetism. By controlling the direction of the current passed into the second magnetic part 511, the magnetic attraction mechanism 50 can generate different magnetic fields toward the sealing structure 30, so that the sealing structure 30 can be attracted to move toward the magnetic attraction mechanism 50 when the magnetic attraction mechanism 50 is energized to generate a magnetic field opposite to that of the first magnetic part 311, and the sealing structure 30 is driven to move away from the magnetic attraction mechanism 50 when the magnetic attraction mechanism 50 is energized to generate the same magnetic field as the first magnetic part 311, thereby realizing the movement of the magnetic attraction mechanism 50 in the valve body 10 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.

[0068] Reference Figures 1 to 4 In one embodiment of the present invention, the magnetic attraction mechanism 50 includes a slider 51 and a driving device 53. The slider 51 is movably disposed on the valve body 10. A second magnetic member 511 is disposed in the slider 51. The driving device 53 is connected to the slider 51 and drives the slider 51 to move.

[0069] In this embodiment, by setting the second magnetic member 511 in the slider 51 and connecting the slider 51 with the driving device 53 to drive the slider 51 to move, the position of the second magnetic member 511 can be changed by the movement of the slider 51, so that the sealing structure 30 can move in the valve body 10 following the change of the position of the second magnetic member 511, so as to realize the opening or closing of the air outlet 131 by the sealing structure 30, and ensure the stable operation of the steam valve 100. Among them, the moving direction of the slider 51 can be set at an angle with the moving direction of the sealing structure 30. At this time, when the slider 51 drives the second magnetic member 511 to move close to the sealing structure 30, the magnetic attraction cooperation between the second magnetic member 511 and the first magnetic member 311 can be used to drive the sealing structure 30 to move in the valve body 10, so that the sealing structure 30 can open the air outlet 131; and when the slider 51 drives the second magnetic member 511 to move away from the sealing structure 30, the magnetic attraction cooperation between the second magnetic member 511 and the sealing structure 30 can be disconnected, so that the sealing structure 30 returns to the original position to close the air outlet 131. Alternatively, the moving direction of the slider 51 can be set parallel to the moving direction of the sealing structure 30. At this time, the first magnetic component 311 and the second magnetic component 511 maintain a magnetic attraction and matching setting, and the slider 51 can be driven to move by a driving device 53 outside the valve body 10, thereby driving the sealing structure 30 to move inside the valve body 10 following the position of the slider 51, thereby achieving more convenient movement control of the sealing structure 30 and further improving the structural stability and reliability of the steam valve 100.

[0070] Reference Figure 1 and Figure 2 In one embodiment of the utility model, the driving device 53 includes an electromagnet 531 and an electromagnetic push rod 533. One end of the electromagnetic push rod 533 is inserted into the electromagnet 531, and the other end of the electromagnetic push rod 533 is connected to the slider 51. The electromagnet 531 drives the electromagnetic push rod 533 to move back and forth, so that the electromagnetic push rod 533 drives the slider 51 to move.

[0071] It is understandable that the driving device 53 can be a hydraulic transmission device or a pneumatic transmission device, which provides power to the slider 51 by utilizing the change of hydraulic pressure or pneumatic pressure. Alternatively, the driving device 53 can be an electromagnetic driving device 53, in which case the driving device 53 can include an electromagnet 531 and an electromagnetic push rod 533. The electromagnet 531 can be a hollow electromagnetic coil winding structure. By movably inserting the electromagnetic push rod 533 in the electromagnet 531 and connecting the slider 51 to the electromagnetic push rod 533, a permanent magnet with a certain magnetism can be arranged inside the electromagnetic push rod 533, and the electromagnet 531 can be turned on and off or the current flow direction in the electromagnet 531 can be changed to make the electromagnet 531 move. 1 changes, so that the electromagnetic push rod 533 can drive the slider 51 to move under the action of the magnetic field. For example, when the magnetic field generated by the electromagnet 531 is the same as the magnetic field of the permanent magnet in the electromagnetic push rod 533, the electromagnetic push rod 533 can be subjected to the force of magnetic repulsion and move in a direction away from the electromagnet 531; or when the magnetic field generated by the electromagnet 531 is different from the magnetic field of the permanent magnet in the electromagnetic push rod 533, the electromagnetic push rod 533 can be subjected to the force of magnetic attraction and move in a direction away from the electromagnet 531. Then, under the change of the magnetic field generated by the electromagnet 531, the electromagnetic push rod 533 can drive the slider 51 to move, thereby ensuring that the sealing structure 30 can realize the opening and closing of the air outlet 131 under the stable driving action of the magnetic attraction mechanism 50, and further improving the structural stability and reliability of the steam valve 100.

[0072] Secondly, a spring or an elastic structure such as a tension spring with a certain elasticity can be arranged between the electromagnet 531 and the electromagnetic push rod 533. When the electromagnet 531 drives the electromagnetic push rod 533 to move in a direction away from the electromagnet 531, the magnetic force between the electromagnetic push rod 533 and the electromagnet 531 can be used to drive the elastic structure to undergo elastic deformation. At this time, when it is necessary to drive the electromagnetic push rod 533 to move in a direction toward the electromagnet 531, the electromagnet 531 can be directly powered off, and then the elastic structure can be used to restore the elastic deformation to drive the electromagnetic push rod 533 to move in a direction toward the electromagnet 531, so that the driving device 53 can realize the movement drive of the battery push rod by the way of turning the electromagnet 531 on and off, which is conducive to reducing the control of the current flow direction of the electromagnet 531, so that the steam valve 100 can achieve a simpler control method, which is convenient for the lightweight design of the steam valve 100.

[0073] Reference Figure 1 , Figure 2 , Figure 5 and Figure 8In one embodiment of the utility model, the steam valve 100 further includes a blast device 70, which is disposed on one side of the valve body 10 and connected to the blast channel 13, and the blast device 70 is used to drive the airflow to flow through the blast channel 13 and the steam channel 11. And / or, the steam valve 100 is further provided with a temperature detection mechanism, which is at least partially disposed 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 channel length of the blast channel 13 is defined as L, 2mm≤L≤30mm.

[0074] 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.

[0075] Secondly, a spoiler rib 111 can be connected to the inner wall of the steam channel 11, and the spoiler rib 111 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 111 during the flow of the steam in the steam channel 11, and the path of 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 water vapor in the steam valve 100 can be further extended by arranging a plurality of spoiler ribs 111 at a certain interval along the flow path of water vapor in the steam channel 11, so as to achieve sufficient condensation and cooling of water vapor in the steam valve 100, and ensure the practicality and reliability of the steam valve 100.

[0076] 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 structure 30 may be fed back to determine whether the air outlet 131 is normally opened and 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 entered the steam passage 11 well to condense and cool the water vapor. At this time, it may be fed back that the sealing structure 30 has not opened the air outlet 131 well, and the user may be warned that the steam valve 100 has a fault. 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.

[0077] 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.

[0078] By setting the channel length L of the blast channel 13 between 2 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 2 mm, a certain space can be provided in the blast channel 13 to set the sealing structure 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.

[0079] Reference Figures 5 to 9In one embodiment of the utility model, the valve body 10 is defined to have a height direction, at least part of the structure of the steam channel 11 is extended along the height direction, at least part of the blast channel 13 overlaps with the steam channel 11 in the height direction, and the blast channel 13 is provided with an air outlet 131 in the overlapping area. The steam channel 11 is provided with a steam inlet 113 and a steam outlet 115, and the steam inlet 113 and the air outlet 131 are arranged at a relative interval.

[0080] In this embodiment, by making at least part of the steam channel 11 extend in the vertical direction, and setting the steam inlet 113 and the steam outlet 115 on the inner wall of the steam channel 11, the steam inlet 113 and the steam outlet 115 can be arranged with a certain spacing in the height direction, so that the water vapor can spread from bottom to top after entering the steam channel 11 through the steam inlet 113 on the steam valve 100, and be discharged from the steam outlet 115 to the environment where the cooking device is located. By making at least part of the blast channel 13 overlap with the steam channel 11 in the vertical direction, the blast channel 13 can be provided with an air outlet 131 in the overlapping channel area. By making the air outlet 131 and the steam inlet 113 relatively spaced, the low-temperature airflow and the water vapor can be directly mixed relative to each other when entering the steam channel 11, which is conducive to making the low-temperature airflow act more quickly on the water vapor just entering the steam channel 11, realizing the rapid cooling of the water vapor by the low-temperature airflow, and further improving the stability and reliability of the steam valve 100.

[0081] Reference Figure 8 In one embodiment of the utility model, the projection of the air outlet 131 along the height direction on the plane where the steam inlet 113 is located is staggered with the steam inlet 113. The horizontal distance between the steam inlet 113 and the air outlet 131 is defined as L1, and the horizontal distance between the steam inlet 113 and the steam outlet 115 is defined as L2, 1 / 2L2≤L1≤2 / 3L2.

[0082] In this embodiment, the steam valve 100 can displace the air outlet 131 with the steam outlet 115 and the steam inlet 113 in the horizontal direction, so that the water vapor can have a longer moving path after entering the steam channel 11 through the steam inlet 113, so that the cold air output by the blast channel 13 can be better mixed with the water vapor in the steam channel 11 and cooled, thereby ensuring the cooling effect of the steam valve 100 on the water vapor. Preferably, the air outlet 131 can be arranged between the steam outlet 115 and the steam inlet 113, so that the water vapor can stably pass through the air outlet 131 during the process of entering the steam channel 11 through the steam inlet 113 and moving toward the steam outlet 115, which is conducive to better extending the moving path of the water vapor in the steam channel 11, and the cold air blown into the steam channel 11 through the air outlet 131 by the blast channel 13 can be more fully mixed with the water vapor, so as to avoid the water vapor entering the steam channel 11 without being cooled and being directly discharged from the steam outlet 115, thereby ensuring the cooling effect of the steam valve 100 on the water vapor, and further improving the structural stability and reliability of the steam valve 100. By limiting the horizontal spacing L1 between the steam inlet 113 and the air outlet 131 and the horizontal spacing L2 between the steam inlet 113 and the steam outlet 115 to meet the condition: 1 / 2L2≤L1≤2 / 3L2, within this range, the air outlet 131 and the steam inlet 113 can have a certain spacing in the horizontal direction, and the steam inlet 113 and the steam outlet 115 can have a certain spacing in the horizontal direction, which is beneficial to ensure that the steam valve 100 has a good condensation effect and better avoid the backflow of water vapor into the blast channel 13. Among them, by making L1 greater than or equal to 1 / 2L2, within this range, there can be a certain distance between the air outlet 131 and the steam inlet 113, avoiding the steam inlet 113 and the air outlet from being too close, which is beneficial to preventing water vapor from entering the steam channel 11 through the steam inlet 113 and directly rushing to the air outlet 131 and backflowing into the blast channel 13, further preventing water vapor accumulation in the blast channel 13; at the same time, by making L1≤2 / 3L2, within this range, it can be avoided that the air outlet 131 is too far away from the steam inlet 113, which may cause a certain probability that part of the water vapor is not cooled by the low-temperature airflow and is directly discharged from the steam outlet 115, so that the low-temperature airflow can be better filled into the steam channel 11 to fully cool the water vapor, thereby ensuring the discharge of trace or low-temperature steam from the steam valve 100, ensuring the stable operation of the steam valve 100, and further improving the structural stability and reliability of the steam valve 100.

[0083] Reference Fig. 9 In one embodiment of the present invention, a projection of the air outlet 131 along the height direction on the plane 113 where the steam inlet is located overlaps with the steam inlet 113 .

[0084] In this embodiment, the steam valve 100 can set the position of the air outlet 131 relative to the steam inlet 113, so that the projection of the air outlet 131 along the height direction on the plane where the steam inlet 113 is located overlaps with the steam inlet 113, so that the airflow blown out from the air outlet 131 can directly contact and cool the water vapor entering the steam channel 11 through the steam inlet 113, and the water vapor can be quickly affected by the cold air after entering the steam channel 11, so as to achieve a faster and more reliable cooling effect on the water vapor in the steam valve 100. In addition, by setting the air outlet 131 relative to the steam inlet 113, part of the cold air blown out from the air outlet 131 can also directly enter the pot body through the steam inlet 113, which is conducive to using the cold air to disturb the air in the pot body, and then dispel the stale smell released in the pot body cavity when the food is heated, reduce the odor of the food after cooking, so that the cooking utensil can achieve a better cooking effect, so that the steam valve 100 can not only achieve cooling and cooling of the water vapor, but also play a certain function of removing the stale smell, further improving the practicality and reliability of the steam valve 100.

[0085] Reference Figure 8 and Fig. 9 In one embodiment of the present invention, the distance between the steam inlet 113 and the air outlet 131 along the height direction is defined as D, and D≥5mm.

[0086] Since water vapor still has a certain airflow velocity when entering the steam channel 11 through the steam inlet 113, if the air outlet 131 is close to the steam inlet 113, it is easy to cause part of the water vapor to rush to the air outlet 131 and condense in the blast channel 13. In this embodiment, by setting the distance D between the steam inlet 113 and the air outlet 131 in the height direction to be greater than or equal to 5 mm, the air outlet 131 and the steam inlet 113 can be spaced a certain distance apart in the height direction, which is conducive to well extending the path of water vapor flowing between the steam inlet 113 and the air outlet 131, reducing the flow rate and flow of water vapor flowing at this distance, avoiding water vapor from directly passing through the air outlet 131 into the blast channel 13, better reducing the water vapor accumulated in the blast channel 13, ensuring the stable operation of the steam valve 100, and further improving the structural stability and reliability of the steam valve 100.
