[0034] In order to avoid the steam being discharged to the surroundings and affecting the humidity and temperature of the indoor environment, and to avoid the user being scalded by the high-temperature steam, a blower passage is provided in the steam valve, so that the low-temperature fluid enters the steam valve through the blower passage, mixes with the steam and is cooled to lower the temperature, and further a small amount of steam or low-temperature steam is discharged from the cooking pot to reduce the influence on the surroundings and the user. When the steam flows through the steam valve, since some of the steam is likely to flow back into the blower passage, the steam is likely to collide with the low-temperature fluid in the blower passage and condense, and furthermore, condensed water is likely to accumulate in the blower passage. Then, the components in the blower passage are likely to be damaged by moisture, affecting the normal operation of the cooking appliance and reducing the structural stability and reliability of the steam valve. In response to the above problems, the present application proposes a steam valve.

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

[0036] In addition, the cooking appliance may be an electric rice cooker, a pressure cooker, a steamer, or the like. Since the cooking appliance usually includes a pot body for heating and cooking food and a pot lid 1000 that closes the pot body to form a sealed cooking appliance, the cooking appliance can stably and reliably perform cooking operations using the food and meet the usage needs of the user. During the process of heating the food in the pot body, when the moisture in the food is heated to a certain temperature, water vapor is generated and fills the pot body, and as the water vapor increases, the air pressure in the pot body gradually rises. At this time, when the cooking appliance is a pressure cooker, the effect of pressure cooking can be realized by utilizing the increase in pressure in the pot body. On the other hand, a steam valve 100 may usually be provided on the pot lid 1000. 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 the sealing pressing plate that seals the opening of the pot body of the pot lid 1000, and by covering the opening of the steam valve 100 communicating with the steam passage 11 with the sealing pressing plate, water vapor may enter the steam passage 11 of the steam valve 100 through the steam inlet 113. Then, by providing the steam outlet 115 communicating with the steam passage 11 of the steam valve 100 on the surface of the pot lid 1000 or exposing the steam outlet 115 of the steam valve 100 on the surface of the pot lid 1000, the water vapor generated in the pot body can be guided and discharged using the steam valve 100, so that the cooking appliance can better maintain the air pressure in the pot body within a desired adjusted air pressure range for cooking, and the stable operation of the cooking appliance can be guaranteed.

[0037] In the present application, by partitioning the inside of the valve body 10 of the steam valve 100 with a partition plate to form a steam passage 11 and a blower passage 13, the water vapor generated in the main body of the pot can be discharged to the environment where the cooking appliance is placed through the steam passage 11. The blower passage may be provided on one side of the steam passage, and by forming a blow-out hole 131 communicating with the steam passage 11 on the inner wall of the blower passage, a relatively low-temperature airflow is passed through the blower passage 13, so that the low-temperature airflow can flow from the blower passage 13 through the blow-out hole 131 into the steam passage 11 and be mixed with the high-temperature water vapor in the steam passage 11, thereby realizing the cooling of the water vapor by the steam valve 100. Further, the temperature of the water vapor discharged from the steam outlet 115 of the steam valve 100 can be lowered, most of the water vapor can be cooled and condensed in the steam valve 100, the amount of the water vapor discharged from the steam valve 100 can be reduced, low-temperature steam discharge or trace steam discharge from the cooking appliance can be realized, and the influence of the high-temperature and high-humidity water vapor discharged from the cooking appliance on the indoor environment or the user can be better reduced, contributing to improving the practicality and reliability of the steam valve 100. By providing the blower passage 13 on one side of the steam passage 11 and providing the blow-out hole 131 between the blower passage 13 and the inner wall of the steam passage 11, the low-temperature airflow flowing through the blower passage 13 can be diffused into the steam passage 11 through the blow-out hole 131. In this case, since the water vapor rising and diffusing in the steam passage 11 can be cooled by using the low-temperature airflow diffusing laterally in the steam passage 11, the cooling effect of the water vapor by the steam valve 100 can be effectively improved. On the other hand, by providing the blow-out hole 131 on the inner walls of the blower passage 13 and the steam passage 11, it is possible to prevent to some extent the water vapor rising in the steam passage 11 from flowing into the blower passage 13 through the blow-out hole 131, making it easier to further reduce the condensed water generated by the condensation of the water vapor in the blower passage 13, avoiding damage to the components of the blower passage 13 due to moisture, and further improving the structural stability and reliability of the steam valve 100.

[0038] On one hand, a movable sealing member 30, which may be a plug or a valve structure provided near the blowing hole 131, is provided inside the steam valve 100. Due to the movement of the sealing member 30 inside the valve body 10, the sealing member 30 can close or cover the blowing hole 131 inside the valve body 10 to close the blowing hole 131, or move to one side of the blowing hole 131 to open the blowing hole 131. Therefore, by providing the sealing member 30 inside the valve body 10 to control the opening and closing of the blowing hole 131, during cooking, first, the sealing member 30 is moved towards the blowing hole 131 to stably close the blowing hole 131, partition the air supply passage 13 and the steam passage 11, and then, after stably passing a low-temperature air flow through the air supply passage 13, the sealing member 30 is moved away from the blowing hole 131 to open the blowing hole 131 so that the low-temperature air flow can stably enter the steam passage 11 to cool the water vapor. At this time, the low-temperature air flow continuously flows out from the blowing hole 131, pushing out the water vapor attempting to enter the air supply passage 13 at the blowing hole 131, and can effectively prevent the reverse flow of water vapor into the air supply passage 13. When it is necessary to stop the cooling and condensation of water vapor, while maintaining the flow of the low-temperature air flow in the air supply passage 13 and the steam passage 11, the sealing member 30 is moved towards the blowing hole 131 to close the blowing hole 131. After the sealing member 30 stably closes the blowing hole 131 to partition the air supply passage 13 and the steam passage 11, the supply of the low-temperature air flow into the air supply passage 13 can be stopped. Furthermore, it can effectively prevent water vapor from flowing back into the air supply passage 13 to form condensed water and accumulating in the air supply passage 13 when switching the supply / supply stop of the low-temperature air flow in the air supply passage 13. It avoids the elements in the air supply passage 13 from being damaged by moisture, reduces the maintenance and inspection frequency of the steam valve 100, contributes to ensuring the stable operation of the steam valve 100, and improves the structural stability and reliability of the steam valve 100 as a whole.

[0039] In addition, when applying the steam valve 100 to cooking appliances such as rice cookers, after the cooking appliance operates until the ingredients in the pot boil, the low-temperature airflow passed through the air supply passage 13 enters the steam passage 11 and diffuses to the inside of the pot body, cooling and bursting the bubbles generated in the pot body, so that the cooking appliance can achieve a better cooking effect. In this case, after the bubble bursting process is completed, the blowing hole 131 is closed using the sealing member 30, and then the supply of low-temperature air to the air supply passage 13 is stopped, effectively preventing the boiling cooking juice that has entered the steam passage 11 from flowing back into the air supply passage 13, further preventing liquid from accumulating in the air supply passage 13, ensuring the normal operation of each component in the air supply 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 in the valve body 10. The air supply passage 13 is provided on one side of the steam passage 11, and a blowing hole communicating with the air supply passage 13 is formed on the inner wall of the steam passage 11, so that the low-temperature airflow flowing in the air supply passage 11 can be blown laterally into the steam passage 13 through the blowing hole. In this way, the upward-flowing water vapor in the steam passage 11 can be blocked and cooled by using the low-temperature airflow that rapidly diffuses into the steam passage 11. Furthermore, the water vapor generated during cooking can be stably and reliably cooled and temperature-reduced using the steam valve 100, reducing the influence of the discharge of high-temperature water vapor from the steam valve 100 on the surroundings. On the other hand, a sealing member 30 is provided in the valve body 10, and the blowing hole 131 is opened and closed by utilizing the movement of the sealing member 30 in the air supply passage 13, so that when switching the supply / supply stop of the low-temperature airflow in the air supply passage 13, it is possible to preferably prevent water vapor from flowing back into the air supply passage 13 and condensing into condensed water and accumulating in the air supply passage 13. Avoiding damage to the elements in the air supply passage 13 due to moisture, reducing the maintenance and inspection frequency of the steam valve 100, contributing to ensuring the stable operation of the steam valve 100, and improving the structural stability and reliability of the steam valve 100 as a whole.

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

[0042] In this embodiment, as can be seen from FIG. 3, FIG. 3 is a flow direction diagram of the steam valve 100 in which the low-temperature air flow entering the steam passage 11 through the blow-out hole 131 and the high-temperature water vapor entering the steam passage 11 through the steam inlet 113 are mixed and flow in the steam passage 11. By extending the steam passage 11 vertically in the valve body 10 and extending the air supply passage 13 horizontally in the valve body 10, the water vapor can flow from bottom to top in the steam passage 11, and the low-temperature air flow can flow into the steam passage 11 horizontally through the blow-out hole 131, so that the direction of the low-temperature air flow flowing into the steam passage 11 through the blow-out hole 131 and the direction of the water vapor flowing in the steam passage 11 can have an included angle. In this case, since the water vapor carries water vapor molecules with a large weight, the flow velocity of the low-temperature air flow horizontally entering the steam passage 11 can be made larger than the flow velocity of the water vapor. Therefore, the low-temperature air flow can enter the steam passage 11 vigorously from the lateral direction, block the rising water vapor, and can significantly reduce the temperature of the water vapor, better prevent the high-temperature water vapor from being discharged from the steam outlet 115 of the steam valve 100, and further improve the cooling effect of the water vapor by the steam valve 100.

[0043] Referring to FIGS. 1, 2 and 6, in one embodiment of the present application, a drive mechanism 50 is further provided in the steam valve. The drive mechanism 50 is connected to the sealing member 30 and moves the sealing member 30 to open and close the blow-out hole 131.

[0044] In this embodiment, a drive mechanism 50, which may be a push rod traction device, a cable traction device, or the like, is provided on the valve body 10 and connected to the sealing member 30, so that the drive mechanism 50 can be moved in the valve body 10, and power can be transmitted to the sealing member 30 by using the drive mechanism 50 to move the sealing member 30. Alternatively, by using the drive mechanism 50 to pull and rotate the sealing member 30, it is also possible to rotate the sealing member 30 in the valve body 10 to approach or move away from the blowing hole 131. Further, by using the drive mechanism 50 to move the sealing member 30 in the air supply passage 13, the steam valve can use the control unit to operate the drive mechanism 50 to realize stable control of the movement of the sealing member 30. Further, the opening and closing of the blowing hole 131 by the sealing member 30 can be realized more stably and reliably, the control and stable operation of the steam valve 100 in the cooking appliance can be guaranteed, the entry of water vapor or bubbles into the air supply passage 13 can be better blocked by using the sealing member 30, and the stability and reliability of the steam valve 100 can be further improved.

[0045] Referring to FIGS. 1 to 6, in an embodiment of the present application, the drive mechanism 50 includes an electromagnet 51 and a push rod structure 53 with one end inserted into the electromagnet 51 and the other end connected to the sealing member 30. When the electromagnet 51 drives the push rod structure 53 to expand and contract, the push rod structure 53 reciprocates the sealing member 30.

[0046] Note that the drive mechanism 50 may include an electromagnet 51 and a push rod structure 53. 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 having a certain magnetism is provided in the push rod structure 53. By turning the electromagnet 51 on and off or switching the direction of the current in the electromagnet 51, the magnetic field generated by the electromagnet 51 can be changed. Therefore, the push rod structure 53 can move the sealing member 30 under the action of the magnetic field. For example, when the magnetic field generated by the electromagnet 51 is the same as the magnetism of the permanent magnet in the push rod structure 53, the push rod structure 53 can receive a magnetic repulsive force and move in a direction away from the electromagnet 51. Or, when the magnetic field generated by the electromagnet 51 is different from the magnetism of the permanent magnet in the push rod structure 53, a magnetic attractive force can be applied to the push rod structure 53 to move it in a direction approaching the electromagnet 51. Furthermore, due to the change in the magnetic field generated by the electromagnet 51, the push rod structure 53 can move the sealing member 30. Therefore, it is guaranteed that the sealing member 30 can open and close the blow hole 131 under the stable drive of the drive mechanism 50, and the structural stability and reliability of the steam valve 100 can be further improved.

[0047] Furthermore, the push rod structure 53 includes an electromagnetic push rod 531 with one end movably inserted into the electromagnet 51, and a traction rod 533 with 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 move telescopically, so that the electromagnetic push rod 531 reciprocally moves the traction rod 533 and the sealing member 30.

[0048] In this embodiment, by configuring the push rod structure 53 to include an electromagnetic push rod 531 and a traction rod 533, a permanent magnet is provided inside 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 under 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 conducted into the steam valve through the traction rod 533 is reduced. Further, by using the traction rod 533 to divide and extend the electromagnetic push rod 53, the driving mechanism 50 can be easily assembled into the steam valve 100, further improving the ease of assembly and practicality of the steam valve 100.

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

[0050] In this embodiment, by disposing an elastic member 55, which may be a spring or a tension spring having a certain elasticity, 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 elastic member 55 can be elastically deformed by utilizing the magnetic biasing force between the electromagnetic push rod 531 and the electromagnet 51. In this case, when it is necessary to move the electromagnetic push rod 531 in a direction toward the electromagnet 51, the power supply to the electromagnet 51 can be directly turned off, and the electromagnetic push rod 531 can be moved in a direction toward the electromagnet 51 by utilizing the recovery of the elastic member 55 from the elastic deformation. Since the driving device 51 can realize the driving of the movement of the electromagnetic push rod by using the on / off of the power supply to the electromagnet 51, the control of the direction of the current of the electromagnet 51 can be reduced, the control of the steam valve 100 can be made easier, and the lightweight design of the steam valve 100 can be facilitated.

[0051] Referring to FIGS. 3 and 5, in one embodiment of the present application, on one side of the traction rod 533, one of a traction concave groove 5333 or a connection boss 5311 is provided, and on the outer peripheral side of the electromagnetic push rod 531, the other of the traction concave groove 5333 or the connection boss 5311 is provided, and the connection boss 5311 is locked in the traction concave groove 5333.

[0052] In this embodiment, a traction concave groove 5333 may be formed on one side of the traction rod 533, and a connection boss 5311 that is locked corresponding to the traction concave groove 5333 may be provided on the outer periphery of the electromagnetic push rod 531. In this case, by locking the connection boss 5311 in the traction concave groove 5333, the connection between the traction rod 533 and the electromagnetic push rod 531 can be realized. Furthermore, since the attachment and detachment of the traction rod 533 and the drive device 51 can be performed more easily, only the drive device 51 can be easily removed from the valve body 10 of the steam valve 100 for repair or inspection. This ensures the stable operation of the steam valve 100 and further improves the practicality and reliability of the steam valve 100.

[0053] Alternatively, a connection boss 5311 may be formed on one side of the traction rod 533, and a traction concave groove 5333 that is locked corresponding to the connection boss 5311 may be provided on the outer periphery of the electromagnetic push rod 531. In this case, by locking the connection boss 5311 in the traction concave groove 5333, the connection between the traction rod 533 and the electromagnetic push rod 531 can be realized. Furthermore, since the attachment and detachment of the traction rod 533 and the drive device 51 can be performed more easily, the practicality and reliability of the steam valve 100 are further improved.

[0054] In one embodiment of the present application, a first magnetic member is provided in the traction rod 533, 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 adsorption with the second magnetic member.

[0055] In this embodiment, by providing a first magnetic member inside the traction rod 533 and a second magnetic member on the traction rod side of the electromagnet 51, when the electromagnetic push rod 531 moves the traction rod 533 in the direction towards the electromagnet 51, the magnetic adsorption between the first magnetic member and the second magnetic member can be utilized so that the electromagnetic push rod 531 can better maintain the current position of the sealing member 30. It is easy to avoid the situation that the electromagnetic push rod 531 moves the traction rod 533 away from the electromagnet 51 due to a malfunction of the electromagnet 51 and affects the stable operation of the steam valve 100. At this time, the magnetic adsorption between the first magnetic member and the second magnetic member can function to a certain extent as an auxiliary to stabilize the traction rod 533. On the other hand, when it is necessary to drive the electromagnetic push rod 531 to move in the direction away from the electromagnet 51, the electromagnetic push rod 531 is driven by using the force generated by the magnetic field of the electromagnet 51 to separate the magnetic adsorption between the first magnetic member and the second magnetic member, ensuring the stable opening and closing of the blow hole 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 magnetism. In this case, the second magnetic member may be a permanent magnet having a magnetism opposite to that of the first magnetic member or a magnetizable metal. Or, the first magnetic member may be a magnetizable metal. In this case, the second magnetic member may be a permanent magnet having a certain magnetism.

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

[0057] In this embodiment, a position limiting groove 15 is provided in the valve body 10, and a position limiting boss 5331 is provided on the outer periphery of the traction rod 533. By this, the traction rod 533 can be provided and moved within the position limiting groove 15, and the position limiting boss 5331 can be brought into contact with the inner wall of the position limiting groove 15. Furthermore, by utilizing the position limiting and guiding by the position limiting boss 5331 and the inner wall of the position limiting groove 15, the deviation of the traction rod 533 within the valve body 10 can be better prevented. Thereby, the traction rod 533 can linearly move in a direction parallel to the inner wall of the position limiting groove 15 within the valve body 10, and the traction rod 533 can more stably move the sealing member 30 up and down to open and close the blowing hole 131. This ensures the stable operation of the steam valve 100 and further improves the structural stability and reliability of the steam valve 100.

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

[0059] In this embodiment, in the plan view of the valve body 10, the steam passage 11 and the air supply passage 13 may be arranged side by side in the front-rear direction. By adopting this arrangement, the layout of the internal space of the valve body 10 can be made more compact, the low-temperature airflow in the air supply passage 13 can be supplied into the steam passage 11 more quickly, the cooling effect of the steam valve 100 on water vapor can be realized better, and the volume of the entire valve body can be made smaller to achieve the miniaturization of the steam valve 100. Furthermore, the thickness of the entire lid 1000 of the pot can be made smaller, and the usability and reliability of the steam valve 100 can be further improved.

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

[0061] In this embodiment, by arranging the steam passage 11, the air supply passage 13, and the drive mechanism 50 in sequence in the front-rear direction, it is possible to realize that the low-temperature air flow flows toward the steam passage 11 in the air supply passage 13 in the front-rear direction, and the sealing member 30 can move in the front-rear direction to open and close the air outlet hole 131, thereby realizing the arrangement of more compact and reliable components in the steam valve 100. It can better ensure the rapid and reliable cooling of water vapor by the low-temperature air flow in the steam valve 100, reduce the overall volume of the steam valve 100, and further improve the practicality and reliability of the steam valve 100.

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

[0063] In this embodiment, the sealing member 30 may be a plug structure that moves in the axial direction of the air outlet hole 131. In this case, an elastic sealing ring 31 may be provided at one end of the sealing member 30 facing the air outlet hole 131, and the outer diameter of the elastic sealing ring 31 may be larger than the aperture diameter of the air outlet hole 131. When the sealing member 30 is driven by the drive mechanism 50 to move in the direction toward the air outlet hole 131 to close the air outlet hole 131, the elastic sealing ring 31 can be abutted against the inner wall of the valve body 10, and the air outlet hole 131 can be covered by the end face of the sealing member 30. In this case, due to the acting force of the drive mechanism 50, the elastic sealing ring 31 and the inner wall of the valve body 10 can be abutted by interference fit. Furthermore, the elastic sealing ring 31 can be used to effectively surround and cover the air outlet hole 131, and the airtight effect between the sealing member 30 and the inner wall of the passage of the air supply passage 13 can be improved. Therefore, the sealing member 30 can close the air outlet hole 131 more stably and reliably, ensure the stable operation of the steam valve 100, and further improve the practicality and reliability of the steam valve 100.

[0064] Referring to FIGS. 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 duct 13 is W, then 0.3 mm ≤ W ≤ 3 mm, and / or when the distance between the elastic seal ring 31 and the blowing hole 131 is H, then 1 mm ≤ H ≤ 50 mm.

[0065] In this embodiment, the elastic seal ring 31 and the inner wall of the air duct 13 are connected by an interference fit. When the elastic seal ring 31 abuts against the inner wall of the air duct 13 to close the blowing hole 131 with the sealing member 30, the deformation amount of the elastic seal ring 31 when it abuts against the inner wall of the air duct 13 and elastically deforms may be 0.3 mm to 3 mm. In this range, a good airtight effect can be achieved by fitting with the inner wall of the air duct 13 by utilizing the elastic deformation of the elastic seal ring 31, and the sealing member 30 can more stably and reliably close the blowing hole 131. By setting the deformation amount W of the elastic sealing member 30 when it abuts against the inner wall of the air duct 13 and elastically deforms to be 0.3 mm or more, the contact area between the elastic seal ring 31 and the inner wall of the valve body 10 can be made sufficient to obtain a good airtight effect. 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 duct 13 and elastically deforms to be 3 mm or less, the risk of damaging the elastic seal ring 31 due to an excessive deformation amount of the elastic seal ring 31 is eliminated. Furthermore, stable closing of the blowing hole 131 by the sealing member 30 is ensured, backflow of water vapor into the air duct 13 is prevented, and the structural stability and reliability of the steam valve 100 can be further improved.

[0066] Then, the distance between the end face of the elastic sealing ring 31 and the inner wall of the air supply passage 13 where the air outlet hole 131 is located can be defined as the moving distance of the sealing member 30 within the air supply passage 13. By setting the distance between the elastic sealing ring 31 and the air outlet hole 131 to be 1 mm to 50 mm, within this range, the effect that the sealing member 30 opens and closes the air outlet hole 131 more quickly can be achieved, and the stable operation of the steam valve 100 can be guaranteed. By setting the distance W between the elastic sealing ring 31 and the air outlet hole 131 to be 1 mm or more, a certain gap can be ensured between the sealing member 30 and the air outlet hole 131, so that the low-temperature air flow can stably flow into the steam passage 11 through the air outlet hole 131 at a certain flow rate to cool the water vapor, and the stable operation of the steam valve 100 can be guaranteed. Also, by setting the distance W between the elastic sealing ring 31 and the air outlet hole 131 to be 50 mm or less, the moving path of the sealing member 30 within the air supply passage 13 is prevented from being too long, and the sealing member 30 can move more quickly within the air supply passage 13 to open and close the air outlet hole 131, avoiding the situation where the moving path of the sealing member 30 is too long and the sealing member 30 fails to cooperate well to close the air outlet hole 131, and improving the structural stability and reliability of the steam valve 100. Preferably, the distance between the elastic sealing ring 31 and the air outlet hole 131 may be set to 5 mm to 10 mm. Within this range, since the sealing member 30 has a moving path that is not too large, the sealing member 30 can open and close the air outlet hole 131 more quickly, the air flow can more stably pass through the gap between the sealing member 30 and the air outlet hole 131, enter the steam passage 11 through the air outlet hole 131 to cool the water vapor, and the structural stability and reliability of the steam valve 100 are further improved.

[0067] Referring to FIGS. 2 to 4, in an embodiment of the present application, the valve body 10 is provided with a mounting hole 151 that penetrates to the inner wall of the air supply passage 13, and the mounting hole 151 is provided opposite to the air outlet hole 131. The sealing member 30 is movably provided within the air supply passage 13, and the sealing member 30 is provided with a sealing jacket 33. One end of the sealing jacket 33 is connected so as to surround the outer periphery of the sealing member 30, and the other end is locked to the mounting hole 151.

[0068] In this embodiment, by providing the mounting hole 151 in the valve body 10 so as to face the blowing hole 131, the sealing member 30 can be arranged to be located between the blowing hole 131 and the mounting hole 151 in the air supply passage 13. Further, the drive mechanism 50 is arranged on one side of the valve body 10, and the drive mechanism 50 is connected to the sealing member 30 through the mounting hole 151, so that the drive mechanism 50 can stably move the sealing member 30 in the air supply passage 13 toward or away from the blowing hole 131, and the opening and closing of the blowing hole 131 by the sealing member 30 can be realized. The drive mechanism 50 can be more easily connected to the sealing member 30 to move the sealing member 30, and a simpler structural design of the steam valve 100 can be realized. The stable operation of the steam valve 100 is ensured, and the structural stability and reliability of the steam valve 100 are further improved.

[0069] In this case, in order to avoid affecting the cooling effect of the low-temperature air flow in the steam valve 100 when the air flow in the air supply passage 13 branches and is discharged through the mounting hole 151, a sealing jacket 33 can be connected so as to surround the outer periphery of the sealing member 30, and one end of the sealing jacket 33 can be connected around the mounting hole 151 after passing through the mounting hole 151 and then turning back. The sealing jacket 33 may have a certain elasticity or a structure that can be bent at a certain angle. During the movement of the sealing member 30, the expansion and contraction caused by the bending of the sealing jacket 33 are utilized to allow the movement of the sealing member 30 in the air supply passage 13 to escape, so that the sealing member 30 can be stably driven by the drive mechanism 50 to open and close the blowing hole 131. By providing the sealing jacket 33, the gap between the mounting hole 151 and the sealing member 30 is blocked by using the sealing jacket 33, and the low-temperature air flow in the air supply passage 13 is prevented from branching and being discharged through the mounting hole 151, so that sufficient low-temperature air flow can pass through the steam passage 11 to cool the water vapor, and the structural stability and reliability of the steam valve 100 can be further improved.

[0070] Referring to FIGS. 2 to 5, in one embodiment of the present application, a fixed seat 17 is provided on the valve body 10. The fixed seat 17 is provided to cover the end portion of the mounting hole 151 opposite to the blowing hole 131. A retraction hole 171 communicating with the mounting hole 151 is provided in the fixed seat 17. A fixed flange 331 abutting against the valve body 10 is provided around the mounting hole 151 on the sealing jacket 33. 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 side of the valve body 10 where the mounting hole 151 is provided. A retraction hole 171 corresponding to the position of the mounting hole 151 is formed on the surface of the fixed seat 17. Therefore, the drive mechanism 50 is connected to the sealing member 30 through the retraction hole 171 and the mounting hole 151, and the sealing member 30 can be moved within the valve body 10. In this case, by folding back one end of the sealing jacket 33 to form the fixed flange 331, the fixed flange 331 is disposed between the outer wall of the valve body 10 and the fixed seat 17. When connecting the fixed seat 17 to the valve body 10, by pressing and fixing the fixed flange 331, further, the connection and fixation of the sealing jacket 33 to the valve body 10 can be stably realized, the sealing effect of the mounting hole 151 by the sealing jacket 33 can be guaranteed, and the structural stability and reliability of the steam valve 100 can be further improved.

[0072] Also, 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, by providing a convex structure on one side of the drive mechanism 50, in the process of the drive mechanism 50 moving the sealing member 30 through the retraction hole 171 to close the blowing hole 131 on the sealing member 30, the contact between the convex structure and the inner wall of the retraction hole 171 realizes the limitation of the moving position of the drive mechanism 50, and the risk of damage to the valve body 10 caused by an excessive acting force between the sealing member 30 and the inner wall of the valve body 10 can be avoided. Furthermore, the stable operation of the steam valve 100 can be better guaranteed, and the structural stability and reliability of the steam valve 100 can be further improved.

[0073] Referring to FIGS. 5 to 8, in one embodiment of the present application, the pot lid 1000 includes a blower device 70. The blower device 70 is provided on one side of the valve body 10 of the steam valve 100 and communicates with the air supply passage 13, and is used to drive the air flow to pass through the air supply passage 13 and the steam passage 11. And / or, turbulence generating ribs are provided in the steam passage 11, and the turbulence generating ribs are 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 the temperature detection mechanism 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 communicating with the air supply passage 13. If the area of the air intake hole is A, then A≥5 mm 2 is satisfied. And / or, if the passage length of the air supply passage 13 is L, then 5 mm≤L≤30 mm.

[0074] In this embodiment, the pot lid 1000 may be provided with a blower device 70, which may be an axial flow fan or a centrifugal fan, etc., connected to the side of the valve body 10 of the steam valve 100. An opening communicating with the air supply passage 13 is provided on one side of the valve body 10, and the blowing end of the blower device 70 covers this opening. In this way, the steam valve 100 can use the blower device 70 to pass a low-temperature air flow into the air supply passage 13, and pass the high-velocity low-temperature air flow into the steam valve 100 to cool and lower the temperature of the water vapor. The stable operation of the steam valve 100 can be guaranteed, and the structural stability and reliability of the steam valve 100 are further improved.

[0075] Furthermore, in the plan view of the pot lid 100, by arranging the blower device 70 and the air supply passage 13 side by side in the left-right direction, the airflow generated by the blower device 70 can be more effectively blown linearly into the air supply passage 13 in the left-right direction. The stable flow of the low-temperature airflow in the air supply passage 13 can be effectively guaranteed, and the low-temperature airflow can be more stably blown into the steam passage 11 to cool down the water vapor, thereby guaranteeing the cooling effect of the water vapor by the steam valve 100. Also, by arranging the blower device 70 and the air supply passage 13 side by side, the arrangement of the blower device 13 and the steam valve 100 can be made more compact, reducing the piping within the pot lid 1000, making the occupied space of the components within the pot lid 1000 smaller, further reducing the overall thickness of the pot lid 1000, and better realizing the miniaturized design of the cooking appliance.

[0076] Furthermore, turbulence generating ribs may be provided on the inner wall of the passage of the steam passage 11. By providing these turbulence generating ribs in the flow path of the water vapor in the steam passage 11, when the water vapor flows through the steam passage 11, it is affected by the blocking action of the turbulence generating ribs, and the flow path of the water vapor in the steam valve 100 can be extended. The water vapor can be more sufficiently mixed with the low-temperature airflow in the steam valve 100 and cooled down, guaranteeing the stable operation of the steam valve 100 and further improving the structural stability and reliability of the steam valve 100. By arranging a plurality of turbulence generating ribs at regular intervals along the flow path of the water vapor in the steam passage 11, the flow path of the water vapor in the steam valve 100 can be further extended, realizing sufficient condensation and temperature reduction of the water vapor in the steam valve 100, and guaranteeing the practicality and reliability of the steam valve 100.

[0077] In addition, a temperature detection mechanism, which may be a thermometer or a temperature sensor, etc., may be provided in the steam passage 11 within the steam valve 100. The temperature detection mechanism can monitor the steam temperature within the steam passage 11 in real time and provide feedback based on the temperature within the steam passage 11 as to whether the sealing member 30 is properly opening and closing the blowout hole 131. In the process of cooling and condensing water vapor by passing a low-temperature air flow through the steam valve 100, when the temperature detection mechanism detects that the temperature within the steam passage 11 is equal to or higher than the temperature of the water vapor, it can be known at this time that the low-temperature air flow has not entered the steam passage 11 properly to cool and condense the water vapor. In this case, it can be fed back that the sealing member 30 is not properly opening the blowout hole 131, warning the user of a malfunction of the steam valve 100. One end of the temperature detection mechanism may be exposed on the pot body side of the steam valve 100. Thereby, the temperature detection mechanism can also be used for detecting the temperature within the pot body during cooking of the cooking appliance, enabling the parts of the cooking appliance to be made more compact, and further improving the practicality and reliability of the cooking appliance.

[0078] In addition, by setting the area A of the air intake hole of the valve body 10 to be 5 cm 2 or more, the intake area of the steam valve 100 can be increased, allowing a sufficient amount of low-temperature air flow to pass through for cooling the water vapor within the air supply passage 13, ensuring stable operation of the steam valve 100, and further improving the structural stability and reliability of the steam valve 100.

[0079] On the one hand, by setting the passage length L of the air supply passage 13 in the range of 5 mm to 30 mm, within this range, a more compact structural design of the valve body 10 and a better layout of the elements can be realized. By setting the passage length L of the air supply passage 13 to be 5 mm or more, a certain space can be provided for arranging the sealing member 30 in the air supply passage 13, which is advantageous for sending the low-temperature air flow through the air supply passage 13 to the steam passage 11 to better cool the water vapor. On the other hand, by setting the passage length L of the air supply passage 13 to be 30 mm or less, within this range, the passage length of the air supply passage 13 is not too long, the occupied space of the valve body 10 can be made smaller, the steam valve 100 can be better arranged in the central region of the pot lid 1000, the water vapor generated in the pot can more quickly flow into the steam valve 100 through the steam inlet 113, and the practicality and reliability of the steam valve 100 are further improved.
