[0034] To prevent water vapor from being discharged into the surrounding area and affecting the humidity and temperature of the indoor environment, as well as to prevent users from being burned by high-temperature steam, a ventilation passage is provided within the steam valve. This allows a low-temperature fluid to pass through the ventilation passage and enter the steam valve, mixing with the water vapor to cool and lower the temperature, and then a small amount of low-temperature steam is discharged from the cooking pot, thereby reducing the impact on the surrounding area and users. When water vapor flows through the steam valve, some of the water vapor tends to flow back into the ventilation passage, which makes it more likely that the water vapor will collide with the low-temperature fluid in the ventilation passage and condense, leading to the accumulation of condensed water within the ventilation passage. This makes components in the ventilation passage more susceptible to moisture damage, affecting the normal operation of the cooking appliance and reducing the structural stability and reliability of the steam valve. To address the above issues, the present application proposes a steam valve.

[0035] 1 to 8, in an embodiment of the present application, the steam valve 100 includes a valve body 10 and a sealing member 30. A steam passage 11 and an air passage 13 are provided within the valve body 10. The air passage 13 is provided on one side of the steam passage 11, and is provided with an outlet hole 131 communicating with the steam passage 11. The sealing member 30 is provided movably within the valve body 10 so as to open and close the outlet hole 131.

[0036] The cooking appliance may be an electric rice cooker, a pressure cooker, a steamer, or the like. A cooking appliance typically includes a pot body for heating and cooking ingredients and a pot lid 1000 for sealing the pot body to form a sealed cooking appliance. This allows the cooking appliance to stably and reliably cook ingredients and meet the user's needs. During the cooking process of heating ingredients in the pot body, when the moisture in the ingredients is heated to a certain temperature, steam is generated and fills the pot body. As the steam increases, the air pressure inside the pot body gradually increases. If the cooking appliance is a pressure cooker, the increased pressure inside the pot body can be used to achieve the effect of pressurized cooking. Meanwhile, the pot lid 1000 may typically be provided with a steam valve 100. The steam inlet 113 of the steam valve 100 may be provided on the pot body side of the pot lid 1000, or the steam inlet 113 may be provided on a sealing plate of the pot lid 1000 that seals the opening of the pot body, and the sealing plate may be used to cover the opening of the steam valve 100 that communicates with the steam passage 11, allowing steam to enter the steam passage 11 of the steam valve 100 through the steam inlet 113. By providing a steam outlet 115 that communicates with the steam passage 11 of the steam valve 100 on the surface of the pot lid 1000 or by exposing the steam outlet 115 of the steam valve 100 on the surface of the pot lid 1000, the steam valve 100 can be used to guide and exhaust steam generated within the pot body, allowing the cookware to better maintain the air pressure within the pot body within the desired regulated air pressure range for cooking and ensuring stable operation of the cookware.

[0037] In the present application, the inside of valve body 10 of steam valve 100 may be divided by a partition plate to form steam passage 11 and air supply passage 13, so that steam generated inside the pot body can be discharged to the environment where the cooking utensil is placed via steam passage 11. By providing an air supply passage on one side of the steam passage and forming blowout holes 131 communicating with steam passage 11 on the inner wall of the air supply passage, a relatively low-temperature air current can be passed through air supply passage 13, and the low-temperature air current can flow from air supply passage 13 through blowout holes 131 into steam passage 11 and mix with high-temperature steam inside steam passage 11, thereby realizing cooling of steam by steam valve 100. Furthermore, the temperature of the water vapor discharged from the steam outlet 115 of the steam valve 100 can be lowered, or most of the water vapor can be cooled and condensed within the steam valve 100, reducing the amount of water vapor discharged from the steam valve 100, thereby enabling low-temperature steam or trace steam to be discharged from the cooking appliance, contributing to better reducing the impact of high-temperature, high-humidity water vapor discharged from the cooking appliance on the indoor environment or the user, and improving the practicality and reliability of the steam valve 100. By providing the air supply passage 13 on one side of the steam passage 11 and providing an outlet hole 131 between the air supply passage 13 and the inner wall of the steam passage 11, the low-temperature air current flowing through the air supply passage 13 can be diffused into the steam passage 11 through the outlet hole 131. In this case, the water vapor rising and diffusing within the steam passage 11 can be cooled by the low-temperature air current diffusing laterally within the steam passage 11, effectively improving the water vapor cooling effect of the steam valve 100. On the other hand, by providing the blow-out holes 131 on the inner walls of the air passage 13 and the steam passage 11, it is possible to some extent to prevent the water vapor rising in the steam passage 11 from flowing to the blow-out holes 131 and entering the air passage 13, which makes it easier to reduce the amount of condensed water generated when the water vapor condenses in the air passage 13, prevents the components of the air passage 13 from being damaged by moisture, and further improves the structural stability and reliability of the steam valve 100.

[0038] Meanwhile, by providing a movable sealing member 30, which may be a plug or valve structure or the like, provided near the blow-out hole 131 within the steam valve 100, the movement of the sealing member 30 within the valve body 10 makes it possible to close the blow-out hole 131 by causing the sealing member 30 to block or cover the blow-out hole 131 within the valve body 10, or to move the sealing member 30 to one side of the blow-out hole 131 to open the blow-out hole 131. Therefore, by providing the sealing member 30 within the valve body 10 and controlling the opening and closing of the blow-out hole 131, during cooking, first the sealing member 30 is moved toward the blow-out hole 131 to stably close the blow-out hole 131 and separate the air passage 13 and the steam passage 11, and then the low-temperature airflow is stably passed through the air passage 13, and the sealing member 30 is moved away from the blow-out hole 131 to open the blow-out hole 131 so that the low-temperature airflow can stably enter the steam passage 11 to cool the water vapor. At this time, the low-temperature airflow continues to flow from the outlet holes 131, pushing out water vapor that is about to enter the air passage 13 at the outlet holes 131, thereby effectively preventing the water vapor from flowing back into the air passage 13. When it is necessary to stop the cooling and condensation of water vapor, the sealing member 30 is moved toward the outlet holes 131 to close the outlet holes 131 while maintaining the flow of low-temperature airflow in the air passage 13 and the steam passage 11, and the supply of low-temperature airflow into the air passage 13 can be stopped after the sealing member 30 stably closes the outlet holes 131 and separates the air passage 13 from the steam passage 11. Furthermore, when switching between supplying and stopping the low-temperature airflow in the air passage 13, it is possible to effectively prevent water vapor from flowing back into the air passage 13 and becoming condensed water, which can accumulate in the air passage 13. This prevents elements in the air passage 13 from being damaged by moisture, reduces the number of maintenance and inspections of the steam valve 100, contributes to ensuring stable operation of the steam valve 100, and improves the structural stability and reliability of the steam valve 100 as a whole.

[0039] Furthermore, when the steam valve 100 is applied to a cooking appliance such as a rice cooker, when the cooking appliance has been operated until the ingredients in the pot have boiled, the low-temperature airflow passed through the air passage 13 enters the steam passage 11 and diffuses into the pot body, cooling and bursting any bubbles that have formed inside the pot body, thereby enabling the cooking appliance to achieve better cooking results. In this case, after the bubble-bursting process is completed, the sealing member 30 is used to close the outlet 131, and the supply of low-temperature air to the air passage 13 is stopped, thereby effectively preventing the cooking liquid that has boiled and entered the steam passage 11 from flowing back into the air passage 13, preventing liquid from accumulating in the air passage 13, ensuring the normal operation of each component in the air passage 13, and further improving the structural stability and reliability of the steam valve 100.

[0040] According to the technical solution of the present application, a steam passage 11 and an air supply passage 13 are provided within the valve body 10, the air supply passage 13 is provided on one side of the steam passage 11, and an outlet hole communicating with the steam passage 13 is formed on the inner wall of the air supply passage 11, so that the low-temperature air flowing through the air supply passage 11 can be blown laterally into the steam passage 13 through the outlet hole. In this way, the water vapor flowing upward within the steam passage 11 can be blocked and cooled by the low-temperature air flow that quickly diffuses into the steam passage 11. Furthermore, the water vapor generated during cooking can be stably and reliably cooled and cooled using the steam valve 100, and the impact of high-temperature water vapor being discharged from the steam valve 100 on the surrounding area can be reduced. On the other hand, by providing a sealing member 30 in the valve body 10 and opening and closing the blow-out hole 131 using the movement of the sealing member 30 in the air passage 13, it is possible to effectively prevent water vapor from flowing back into the air passage 13 and becoming condensed water that accumulates in the air passage 13 when switching between supplying and stopping the low-temperature air flow in the air passage 13. This prevents elements in the air passage 13 from being damaged by moisture, reduces the number of maintenance and inspections of the steam valve 100, contributes to ensuring stable operation of the steam valve 100, and improves the structural stability and reliability of the steam valve 100 as a whole.

[0041] 1 to 3, in one embodiment of the present application, if valve body 10 has a vertical direction and a horizontal direction, steam passage 11 extends in the vertical direction, and air passage 13 extends in the horizontal direction.

[0042] 3, in the present embodiment, the low-temperature air current that has entered the steam passage 11 through the outlet holes 131 and the high-temperature steam that has entered the steam passage 11 through the steam inlet 113 are mixed and flow through the steam passage 11 in the steam valve 100. By providing the steam passage 11 extending in the vertical direction within the valve body 10 and providing the air supply passage 13 extending horizontally within the valve body 10, it is possible for the steam to flow from bottom to top within the steam passage 11 and for the low-temperature air current to flow horizontally into the steam passage 11 through the outlet holes 131, and for the direction of the low-temperature air current flowing into the steam passage 11 through the outlet holes 131 to form an included angle with the direction of the steam flowing through the steam passage 11. In this case, since the water vapor carries heavy water vapor molecules, the flow rate of the low-temperature air flow entering horizontally into the steam passage 11 can be made greater than the flow rate of the water vapor, so that the low-temperature air flow enters the steam passage 11 from the side with force, blocking the rising water vapor and significantly reducing the temperature of the water vapor, which better prevents high-temperature water vapor from being discharged from the steam outlet 115 of the steam valve 100 and further improves the cooling effect of the water vapor by the steam valve 100.

[0043] Referring to Figures 1, 2 and 6, in one embodiment of the present application, the steam valve is further provided with a driving mechanism 50, which is connected to the sealing member 30 and moves the sealing member 30 to open and close the blowing hole 131.

[0044] In this embodiment, the valve body 10 is provided with a drive mechanism 50, which may be a push rod puller or a cable puller, and is connected to the sealing member 30. This allows the drive mechanism 50 to move within the valve body 10, and the drive mechanism 50 can be used to transmit power to the sealing member 30 to move it. Alternatively, the drive mechanism 50 can be used to pull and rotate the sealing member 30, thereby rotating the sealing member 30 within the valve body 10 to move it closer to or away from the outlet 131. Furthermore, by using the drive mechanism 50 to move the sealing member 30 within the air passage 13, the steam valve can operate the drive mechanism 50 using a control unit to stably control the movement of the sealing member 30. Furthermore, this allows the sealing member 30 to more stably and reliably open and close the outlet 131, ensuring the control and stable operation of the steam valve 100 within the cooking appliance. The sealing member 30 can be used to better block steam or bubbles from entering the air passage 13, further improving the stability and reliability of the steam valve 100.

[0045] 1 to 6, in one embodiment of the present application, the driving mechanism 50 includes an electromagnet 51 and a push rod structure 53, one end of which is inserted into the electromagnet 51 and the other end of which is connected to the sealing member 30. The electromagnet 51 drives the push rod structure 53 to extend and retract, thereby causing the push rod structure 53 to reciprocate the sealing member 30.

[0046] The driving mechanism 50 may include an electromagnet 51 and a push rod structure 53, and the electromagnet 51 may be a hollow electromagnetic coil winding structure. The push rod structure 53 is movably inserted into the electromagnet 51, and a permanent magnet with a certain magnetic property is provided within the push rod structure 53. The magnetic field generated by the electromagnet 51 can be changed by turning on and off the electromagnet 51 or by switching the direction of the current flow within the electromagnet 51, so that the push rod structure 53 can move the sealing member 30 under the action of the magnetic field. For example, if the magnetic field generated by the electromagnet 51 and the magnetic property of the permanent magnet within the push rod structure 53 are the same, the push rod structure 53 will be moved away from the electromagnet 51 due to a magnetic repulsive force. Alternatively, if the magnetic field generated by the electromagnet 51 and the magnetic property of the permanent magnet within the push rod structure 53 are different, the push rod structure 53 will be moved toward the electromagnet 51 due to a magnetic attractive force. Furthermore, the push rod structure 53 can move the sealing member 30 due to changes in the magnetic field generated by the electromagnet 51, ensuring that the sealing member 30 can open and close the blowing hole 131 under stable driving by the driving mechanism 50, further improving the structural stability and reliability of the steam valve 100.

[0047] Furthermore, the push rod structure 53 includes an electromagnetic push rod 531 having one end movably inserted into the electromagnet 51, and a traction rod 533 having one end connected to the electromagnetic push rod 531 and the other end connected to the sealing member 30. The electromagnet 51 drives the electromagnetic push rod 531 to extend and retract, thereby causing the electromagnetic push rod 531 to move back and forth between the traction rod 533 and the sealing member 30.

[0048] In this embodiment, the push rod structure 53 includes an electromagnetic push rod 531 and a traction rod 533, and a permanent magnet is provided in the electromagnetic push rod 531. The electromagnetic push rod 531 is inserted into the electromagnet 51 to utilize the magnetic attraction with the electromagnet 51, and the traction rod 533 can be connected to the electromagnetic push rod 531. In this way, when the electromagnetic push rod 531 moves due to the action of the electromagnet 51, the traction rod 533 can be moved. The traction rod 533 is formed with a structure that does not conduct magnetism, and the magnetic field of the electromagnetic push rod 531 that is transmitted into the steam valve via the traction rod 533 is reduced. In addition, the traction rod 533 is used to divide and extend the electromagnetic push rod 53, which makes it easier to assemble the drive mechanism 50 into the steam valve 100, further improving the ease of assembly and practicality of the steam valve 100.

[0049] Referring to FIG. 5, in one embodiment of the present application, the driving device 51 further includes an elastic member 55 , which is fitted onto the electromagnetic push rod 531 to connect the electromagnet 51 and the electromagnetic push rod 531 .

[0050] In this embodiment, an elastic member 55, which may be a spring or a tension spring having a certain elasticity, is disposed between the electromagnet 51 and the electromagnetic push rod 531. When the electromagnet 51 moves the electromagnetic push rod 531 in a direction away from the electromagnet 51, the magnetic biasing force between the electromagnetic push rod 531 and the electromagnet 51 can be used to elastically deform the elastic member 55. In this case, when it is necessary to move the electromagnetic push rod 531 in a direction toward the electromagnet 51, the electromagnet 51 can be directly turned off, and the recovery of the elastic member 55 from elastic deformation can be used to move the electromagnetic push rod 531 in the direction toward the electromagnet 51. Because the drive unit 51 can drive the movement of the electromagnetic push rod by turning on and off the current to the electromagnet 51, control of the direction of the current to the electromagnet 51 can be reduced, making it easier to control the steam valve 100 and facilitating a lightweight design of the steam valve 100.

[0051] 3 and 5, in one embodiment of the present application, one side of the traction rod 533 is provided with either a traction groove 5333 or a connecting boss 5311, and the other side of the electromagnetic push rod 531 is provided with either the traction groove 5333 or a connecting boss 5311, and the connecting boss 5311 is engaged with the traction groove 5333.

[0052] In this embodiment, a traction groove 5333 may be formed on one side of the traction rod 533, and a connecting boss 5311 may be provided on the outer periphery of the electromagnetic push rod 531, which is engaged with the traction groove 5333. In this case, the connection boss 5311 may be engaged with the traction groove 5333 to realize the connection between the traction rod 533 and the electromagnetic push rod 531. Furthermore, the traction rod 533 may be more easily attached and detached from the actuator 51, so that the actuator 51 may be easily removed from the valve body 10 of the steam valve 100 for repair or inspection. This ensures stable operation of the steam valve 100 and further improves the practicability and reliability of the steam valve 100.

[0053] Alternatively, a connecting boss 5311 may be formed on one side of the traction rod 533, and a traction groove 5333 that is engaged with the connecting boss 5311 may be provided on the outer periphery of the electromagnetic push rod 531. In this case, by engaging the connecting boss 5311 with the traction groove 5333, the traction rod 533 and the electromagnetic push rod 531 can be connected, and the traction rod 533 can be more easily attached and detached from the driving device 51, further improving the practicality and reliability of the steam valve 100.

[0054] In one embodiment of the present application, a first magnetic member is provided within the traction rod 533, and a second magnetic member is provided on the traction rod 533 side of the electromagnet 51, and the first magnetic member is used for magnetic attraction with the second magnetic member.

[0055] In this embodiment, a first magnetic member is provided inside the traction rod 533, and a second magnetic member is provided on the traction rod side of the electromagnet 51. When the electromagnetic push rod 531 moves the traction rod 533 toward the electromagnet 51, the magnetic attraction between the first magnetic member and the second magnetic member can be used to enable the electromagnetic push rod 531 to better maintain the current position of the sealing member 30. This makes it easier to avoid a malfunction of the electromagnet 51 causing the electromagnetic push rod 531 to move the traction rod 533 away from the electromagnet 51, which would affect the stable operation of the steam valve 100. The magnetic attraction between the first magnetic member and the second magnetic member at this time can help to stabilize the traction rod 533 to a certain extent. On the other hand, when it is necessary to drive the electromagnetic push rod 531 to move in a direction away from the electromagnet 51, the force of the magnetic field of the electromagnet 51 is used to drive the electromagnetic push rod 531, separating the magnetic attraction between the first magnetic member and the second magnetic member, thereby ensuring stable opening and closing of the outlet 131 by the sealing member 30 and further improving the structural stability and reliability of the steam valve 100. Here, the first magnetic member may be a permanent magnet having a certain magnetic property, and in this case, the second magnetic member may be a permanent magnet or a magnetic metal having a magnetic property opposite to that of the first magnetic member. Alternatively, the first magnetic member may be a magnetic metal, and in this case, the second magnetic member may be a permanent magnet having a certain magnetic property.

[0056] 3 to 5, in one embodiment of the present application, a position limiting groove 15 is provided in the valve body 10, a traction rod 533 is movably provided in the position limiting groove 15, and a position limiting boss 5331 is provided on the outer periphery of the traction rod 533, and the position limiting boss 5331 abuts against two opposing inner walls of the position limiting groove 15.

[0057] In this embodiment, a position limiting groove 15 is provided within the valve body 10, and a position limiting boss 5331 is provided on the outer periphery of the pulling rod 533. This allows the pulling rod 533 to be disposed within the position limiting groove 15 and move, with the position limiting boss 5331 abutting against the inner wall of the position limiting groove 15. Furthermore, the position limiting and guiding functions of the position limiting boss 5331 and the inner wall of the position limiting groove 15 are utilized to better prevent the pulling rod 533 from shifting within the valve body 10. This allows the pulling rod 533 to move linearly within the valve body 10 in a direction parallel to the inner wall of the position limiting groove 15, more stably moving the sealing member 30 up and down to open and close the outlet port 131. This ensures stable operation of the steam valve 100, and further improves the structural stability and reliability of the steam valve 100.

[0058] 3 and 4, in one embodiment of the present application, if the valve body 10 has a front-to-rear direction in a plan view, the steam passage 11 and the air passage 13 are arranged side by side in the front-to-rear direction, and the drive mechanism 50 is provided on one side of the air passage 13.

[0059] In this embodiment, the steam passage 11 and the air supply passage 13 may be arranged side by side in the front-to-rear direction in a plan view of the valve body 10. This arrangement makes the internal space of the valve body 10 more compact, allowing the low-temperature airflow in the air supply passage 13 to be supplied more quickly to the steam passage 11, improving the cooling effect of the steam valve 100 on water vapor, and reducing the overall volume of the valve body to achieve a more compact steam valve 100. Furthermore, the overall thickness of the pot lid 1000 can be reduced, further improving the usability and reliability of the steam valve 100.

[0060] Furthermore, in one embodiment of the present application, the steam passage 11, the air passage 13, and the drive mechanism 50 are arranged in sequence in the front-rear direction.

[0061] In this embodiment, the steam passage 11, the air passage 13, and the drive mechanism 50 are arranged in sequence in the front-to-rear direction, which allows the low-temperature airflow to flow in the front-to-rear direction within the air passage 13 toward the steam passage 11, and allows the sealing member 30 to move in the front-to-rear direction to open and close the blowing hole 131, thereby realizing a more compact and reliable arrangement of components within the steam valve 100. This better ensures that the low-temperature airflow within the steam valve 100 cools the steam quickly and reliably, while reducing the overall volume of the steam valve 100 and further improving the practicality and reliability of the steam valve 100.

[0062] 3 and 4, in one embodiment of the present application, an elastic seal ring 31 is provided at one end of the sealing member 30 facing the blowing hole 131, and the elastic seal ring 31 abuts against the inner wall of the air passage 13 and is used to cover the blowing hole 131.

[0063] In this embodiment, the sealing member 30 may have a plug structure that moves in the axial direction of the blow-out hole 131. In this case, an elastic seal ring 31 may be provided at one end of the sealing member 30 facing the blow-out hole 131, and the outer diameter of the elastic seal ring 31 may be larger than the diameter of the blow-out hole 131. When the sealing member 30 is driven by the drive mechanism 50 to move in the direction toward the blow-out hole 131 and close the blow-out hole 131, the elastic seal ring 31 abuts against the inner wall of the valve body 10, and the end surface of the sealing member 30 can cover the blow-out hole 131. In this case, the force of the drive mechanism 50 can cause the elastic seal ring 31 to abut against the inner wall of the valve body 10 through a tight fit, and further, the elastic seal ring 31 can be used to effectively surround and cover the blow-out hole 131, improving the airtight effect between the sealing member 30 and the inner wall of the air supply passage 13, so that the sealing member 30 can more stably and reliably close the blow-out hole 131, ensuring stable operation of the steam valve 100 and further improving the practicability and reliability of the steam valve 100.

[0064] 3 and 4, in one embodiment of the present application, when the deformation amount of the elastic seal ring 31 when it abuts against the inner wall of the air passage 13 is W, it satisfies 0.3 mm≦W≦3 mm, and / or when the distance between the elastic seal ring 31 and the blow-out hole 131 is H, it satisfies 1 mm≦H≦50 mm.

[0065] In this embodiment, the elastic seal ring 31 is connected to the inner wall of the air passage 13 by an interference fit. When the elastic seal ring 31 abuts against the inner wall of the air passage 13 to close the blow-out hole 131 with the sealing member 30, the elastic seal ring 31 may be elastically deformed by 0.3 mm to 3 mm. In this range, the elastic deformation of the elastic seal ring 31 is utilized to fit into the inner wall of the air passage 13, achieving a good airtight seal, and the sealing member 30 can more stably and reliably close the blow-out hole 131. By setting the deformation W of the elastic sealing member 30 to 0.3 mm or more when it abuts against the inner wall of the air passage 13, the contact area between the elastic seal ring 31 and the inner wall of the valve body 10 is sufficient, resulting in a good airtight seal. On the other hand, by setting the deformation amount W of the elastic sealing member 30 when it abuts against the inner wall of the air passage 13 to 3 mm or less, the risk of damaging the elastic sealing ring 31 due to excessive deformation of the elastic sealing ring 31 is eliminated, and stable closure of the blowing hole 131 by the sealing member 30 is guaranteed, preventing backflow of water vapor into the air passage 13, and further improving the structural stability and reliability of the steam valve 100.

[0066] The distance between the end face of the elastic seal ring 31 and the inner wall of the air passage 13 where the blow-out hole 131 is located can be defined as the travel distance of the sealing member 30 within the air passage 13. By setting the distance between the elastic seal ring 31 and the blow-out hole 131 to 1 mm to 50 mm, the sealing member 30 can open and close the blow-out hole 131 more quickly, ensuring stable operation of the steam valve 100. By setting the distance W between the elastic seal ring 31 and the blow-out hole 131 to 1 mm or more, a constant gap can be secured between the sealing member 30 and the blow-out hole 131, allowing the low-temperature airflow to stably flow into the steam passage 11 through the blow-out hole 131 at a constant flow rate to cool the water vapor, ensuring stable operation of the steam valve 100. Furthermore, by setting the distance W between the elastic seal ring 31 and the outlet hole 131 to 50 mm or less, the movement path of the sealing member 30 within the air passage 13 is not too long, allowing the sealing member 30 to move more quickly within the air passage 13 to open and close the outlet hole 131, preventing the sealing member 30 from failing and being unable to cooperate to close the outlet hole 131 if the movement path of the sealing member 30 is too long, thereby improving the structural stability and reliability of the steam valve 100. Preferably, the distance between the elastic seal ring 31 and the outlet hole 131 may be 5 mm to 10 mm. Within this range, the sealing member 30 has a certain movement path that is not too large, allowing the sealing member 30 to open and close the outlet hole 131 more quickly and allowing airflow to pass more stably through the gap between the sealing member 30 and the outlet hole 131, via the outlet hole 131, into the steam passage 11 to cool the water vapor, further improving the structural stability and reliability of the steam valve 100.

[0067] 2 to 4, in one embodiment of the present application, a mounting hole 151 is provided in the valve body 10, which penetrates to the inner wall of the air passage 13, and the mounting hole 151 is provided opposite the blow-out hole 131. The sealing member 30 is provided movably within the air passage 13, and the sealing member 30 is provided with a sealing jacket 33, one end of which is connected to surround the outer periphery of the sealing member 30 and the other end of which is engaged with the mounting hole 151.

[0068] In this embodiment, by providing a mounting hole 151 in the valve body 10 facing the outlet hole 131, the sealing member 30 can be disposed in the air passage 13 between the outlet hole 131 and the mounting hole 151. Furthermore, by disposing the drive mechanism 50 on one side of the valve body 10 and connecting the drive mechanism 50 to the sealing member 30 through the mounting hole 151, the drive mechanism 50 can stably move the sealing member 30 toward or away from the outlet hole 131 within the air passage 13, thereby enabling the sealing member 30 to open or close the outlet hole 131. This makes it easier to connect the drive mechanism 50 to the sealing member 30 and move it, thereby achieving a simpler structural design for the steam valve 100. This ensures stable operation of the steam valve 100 and further improves the structural stability and reliability of the steam valve 100.

[0069] In this case, to prevent the airflow in the air passage 13 from branching off and being discharged through the mounting hole 151 and affecting the cooling effect of the low-temperature airflow in the steam valve 100, a sealing jacket 33 can be connected to surround the outer periphery of the sealing member 30, and one end of the sealing jacket 33 can be passed through the mounting hole 151 and then folded back to connect around the mounting hole 151. This sealing jacket 33 may have a certain elasticity or may have a structure that allows it to be bent at a certain angle. During movement of the sealing member 30, expansion and contraction caused by bending the sealing jacket 33 can be used to relieve movement of the sealing member 30 in the air passage 13, so that the sealing member 30 can be driven by the drive mechanism 50 to stably open and close the blowout hole 131. By providing the sealing jacket 33, the gap between the mounting hole 151 and the sealing member 30 is blocked using the sealing jacket 33, preventing the low-temperature air flow in the air passage 13 from branching off and being discharged through the mounting hole 151, and allowing a sufficient low-temperature air flow to pass through the steam passage 11 to cool the water vapor, thereby further improving the structural stability and reliability of the steam valve 100.

[0070] 2 to 5, in one embodiment of the present application, a fixed seat 17 is provided on the valve body 10, and the fixed seat 17 is provided so as to cover the end of the mounting hole 151 opposite to the blow-out hole 131, and the fixed seat 17 is provided with a retraction hole 171 that corresponds to and communicates with the mounting hole 151. The sealing jacket 33 is provided with a fixed flange 331 that abuts against the valve body 10 around the mounting hole 151, and the fixed seat 17 abuts against the side of the fixed flange 331 opposite to the mounting hole 151.

[0071] In this embodiment, the fixed seat 17 may be connected to the valve body 10 on the side where the mounting hole 151 is provided, and a retraction hole 171 may be formed on the surface of the fixed seat 17 corresponding to the position of the mounting hole 151. The driving mechanism 50 may be connected to the sealing member 30 through the retraction hole 171 and the mounting hole 151 to move the sealing member 30 within the valve body 10. In this case, one end of the sealing jacket 33 may be folded back to form a fixing flange 331, which may be disposed between the outer wall of the valve body 10 and the fixed seat 17. When the fixed seat 17 is connected to the valve body 10, the fixing flange 331 may be pressed and fixed. This may further stably connect and fix the sealing jacket 33 to the valve body 10, ensure the sealing effect of the sealing jacket 33 on the mounting hole 151, and further improve the structural stability and reliability of the steam valve 100.

[0072] Alternatively, the inner wall of the retraction hole 171 may have a certain inclination angle, and the inner diameter of the retraction hole 171 may gradually increase in the direction away from the sealing member 30. In this case, a protruding structure may be provided on one side of the driving mechanism 50. When the driving mechanism 50 passes through the retraction hole 171 to move the sealing member 30 and cause the sealing member 30 to close the blowing hole 131, the protruding structure may abut against the inner wall of the retraction hole 171, thereby limiting the movement position of the driving mechanism 50 and avoiding the risk of damage to the valve body 10 due to excessive force acting between the sealing member 30 and the inner wall of the valve body 10. This further ensures stable operation of the steam valve 100 and further improves the structural stability and reliability of the steam valve 100.

[0073] 5 to 8, in one embodiment of the present application, the pot lid 1000 includes an air blower 70, which is provided on one side of the valve body 10 of the steam valve 100, communicates with the air passage 13, and is used to drive airflow to pass through the air passage 13 and the steam passage 11. And / or, a turbulence generating rib is provided in the steam passage 11, and the turbulence generating rib is arranged in the steam flow path of the steam passage 11. And / or, the steam valve 100 is further provided with a temperature detection mechanism, at least a part of which is provided in the steam passage 11, and is used to detect the steam temperature in the steam passage 11. And / or, the valve body 10 is further provided with an air intake hole which communicates with the air passage 13, and where A is the area of ​​the air intake hole, A≧5 mm 2 And / or, when the length of the air passage 13 is L, 5 mm≦L≦30 mm.

[0074] In this embodiment, the pot lid 1000 may be provided with a blower 70, which may be an axial fan or a centrifugal fan, connected to the valve body 10 side of the steam valve 100. An opening communicating with the air passage 13 is provided on one side of the valve body 10, and this opening is covered by the outlet end of the blower 70. This allows the steam valve 100 to use the blower 70 to pass a low-temperature air current through the air passage 13, and to pass a high-speed low-temperature air current through the steam valve 100 to cool and lower the temperature of the water vapor, thereby ensuring stable operation of the steam valve 100 and further improving the structural stability and reliability of the steam valve 100.

[0075] Furthermore, by arranging the air blower 70 and the air passage 13 side by side in the left-right direction when viewed from above on the pot lid 100, the airflow generated by the air blower 70 can be blown more smoothly and linearly into the air passage 13 in the left-right direction, effectively ensuring a stable flow of low-temperature airflow within the air passage 13, allowing the low-temperature airflow to be blown more stably into the steam passage 11 to cool and lower the temperature of the water vapor, and ensuring the cooling and lowering effect of the water vapor by the steam valve 100. Also, by arranging the air blower 70 and the air passage 13 side by side, the arrangement of the air blower 13 and the steam valve 100 can be made more compact, reducing the amount of piping within the pot lid 1000 and reducing the space occupied by components within the pot lid 1000, further reducing the overall thickness of the pot lid 1000 and better achieving a more compact design for the cookware.

[0076] Furthermore, turbulence-generating ribs may be provided on the inner wall of the steam passage 11. By providing these turbulence-generating ribs in the steam flow path within the steam passage 11, the steam is blocked by the turbulence-generating ribs as it flows through the steam passage 11, thereby extending the steam flow path within the steam valve 100 and allowing the steam to be more thoroughly mixed with the low-temperature airflow within the steam valve 100 and cooled, thereby ensuring stable operation of the steam valve 100 and further improving the structural stability and reliability of the steam valve 100. By providing a plurality of turbulence-generating ribs at regular intervals along the steam flow path within the steam passage 11, the steam flow path within the steam valve 100 can be further extended, allowing sufficient condensation and cooling of the steam within the steam valve 100 to be achieved, and ensuring the practicality and reliability of the steam valve 100.

[0077] Additionally, a temperature detection mechanism, such as a thermometer or temperature sensor, may be provided in the steam passage 11 of the steam valve 100. The temperature detection mechanism monitors the steam temperature in the steam passage 11 in real time and provides feedback based on the temperature in the steam passage 11 as to whether the sealing member 30 is properly opening and closing the outlet 131. During the process of passing low-temperature air through the steam valve 100 to cool and condense the water vapor, if the temperature detection mechanism detects that the temperature in the steam passage 11 is equal to or higher than the water vapor temperature, it is determined that the low-temperature air is not properly entering the steam passage 11 to cool and condense the water vapor. In this case, feedback is provided that the sealing member 30 is not properly opening the outlet 131, thereby alerting the user of a malfunction of the steam valve 100. The temperature detection mechanism may have one end exposed on the pot body side of the steam valve 100, allowing it to be used to detect the temperature inside the pot body during cooking, thereby enabling the components of the cookware to be more compact and further improving the practicality and reliability of the cookware.

[0078] In addition, the area A of the intake hole of the valve body 10 is 5 cm 2 By setting the range above, the intake area of ​​the steam valve 100 can be increased, a sufficient amount of low-temperature air can be passed through the air passage 13 to cool the water vapor, and stable operation of the steam valve 100 can be ensured, thereby further improving the structural stability and reliability of the steam valve 100.

[0079] On the other hand, by setting the passage length L of the air supply passage 13 in the range of 5 mm to 30 mm, a compact structural design and element layout of the valve body 10 can be more effectively achieved. Setting the passage length L of the air supply passage 13 to 5 mm or more allows a certain amount of space to be provided within the air supply passage 13 for arranging the sealing member 30, which is advantageous for sending a low-temperature airflow through the air supply passage 13 to the steam passage 11 and more effectively cooling the water vapor. On the other hand, by setting the passage length L of the air supply passage 13 to 30 mm or less, the passage length of the air supply passage 13 is not too long within this range, allowing the space occupied by the valve body 10 to be reduced, allowing the steam valve 100 to be more effectively positioned in the central region of the pot lid 1000, which allows water vapor generated in the pot to more quickly flow into the steam valve 100 through the steam inlet 113, further improving the practicality and reliability of the steam valve 100.

[0080] The present application further proposes a pot lid 1000. This pot lid 1000 includes a lid body 200 and a steam valve 100, and the specific structure of this steam valve 100 is referred to in the above embodiments.
