[0002] As the pace of life accelerates, consumers have an increasing demand for fast cooking. The cooking speed of an electric rice cooker is positively correlated with the heating power. In order to speed up the cooking speed, the heating power can be increased. However, increasing the power easily causes foam to overflow from the steam channel. Therefore, when the electric rice cooker uses high power, a larger steam channel is required to avoid overflow during the cooking process. However, when the electric rice cooker is not boiling or is heated at low power, an overly large steam channel easily causes energy and water loss, reducing the energy efficiency of the electric rice cooker. However, the steam flow area in the steam valve of the existing cooking utensils is usually fixed and cannot be adjusted, and cannot be matched with the different powers of the cooking utensils.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] like Figures 1 to 5 As shown, an embodiment of the present invention provides a steam valve, comprising: a valve body 10, the valve body 10 having a channel 11 and an air outlet 12 connected to the channel 11; a rotating structure 20, arranged in the channel 11, the area between the rotating structure 20 and the inner wall of the channel 11 is a flow area, the rotating structure 20 is rotatably arranged to adjust the minimum flow area of ​​the flow area; a first magnetic attraction part 30, arranged on the rotating structure 20; a driving structure, arranged outside the valve body 10, the driving structure has magnetism, and the driving structure cooperates with the first magnetic attraction part 30 to rotate the rotating structure 20. Among them, the minimum flow area of ​​the flow area can be understood as the minimum area of ​​all radial cross sections of the flow area.

[0025] With this solution, the driving structure and the first magnetic attraction portion 30 cooperate to drive the rotating structure 20 to rotate, thereby adjusting the minimum flow area in the valve body 10, which can also be understood as adjusting the steam discharge volume. With this solution, the minimum flow area can be adjusted according to the heating power of the cooking utensil, thereby avoiding overflow and ensuring the energy efficiency of the cooking utensil. For example, when the cooking utensil is heated at low power, the minimum flow area is adjusted to be relatively small by adjusting the position of the rotating structure 20 to avoid excessive heat loss. When the cooking utensil is heated at high power, the minimum flow area is adjusted to be relatively large to quickly discharge steam and avoid overflow of foam and food.

[0026] Moreover, the scheme adopts a structure with magnetic force, which is simple in structure and easy to control and adjust. For example, the first magnetic attraction part 30 can be adsorbed or released by adjusting the magnetic force of the driving structure, or the first magnetic attraction part 30 can be adsorbed or released by changing the position of the driving structure. Among them, the first magnetic attraction part 30 can be set as a magnet or an iron core.

[0027] In this embodiment, the rotating structure 20 has a first position and a second position. When the rotating structure 20 is in the first position, the value of the minimum flow area is A, and when the rotating structure 20 is in the second position, the value of the minimum flow area is B, A<B, and the driving structure includes: a second magnetic attraction part 40, which is movably arranged, and the second magnetic attraction part 40 has an attraction position and a release position; wherein, when the second magnetic attraction part 40 is in the attraction position, the second magnetic attraction part 40 attracts the first magnetic attraction part 30, and the rotating structure 20 rotates to the first position; when the second magnetic attraction part 40 is in the release position, the second magnetic attraction part 40 releases the first magnetic attraction part 30, and the rotating structure 20 rotates to the second position under the action of gravity. In this way, by changing the position of the second magnetic attraction part 40, the magnitude of the magnetic force applied by the second magnetic attraction part 40 to the first magnetic attraction part 30 can be adjusted, thereby attracting the first magnetic attraction part 30 or releasing the first magnetic attraction part 30. The absorption here means that the two magnetic attraction parts attract each other to limit, but do not contact.

[0028] In this embodiment, the driving structure also includes an electromagnet 50 and a reset elastic member 60, and the reset elastic member 60 cooperates with the second magnetic attraction part 40; when the electromagnet 50 is powered on, the electromagnet 50 absorbs the second magnetic attraction part 40 to move the second magnetic attraction part 40 to the release position; when the electromagnet 50 is powered off, the reset elastic member 60 drives the second magnetic attraction part 40 to move to the attracted position. That is, through the cooperation of the electromagnet 50 and the reset elastic member 60, the automatic position switching of the second magnetic attraction part 40 can be achieved, and the operation is convenient. Among them, the reset elastic member 60 is a spring, and the two ends of the spring are respectively in contact with the second magnetic attraction part 40 and the electromagnet 50.

[0029] In this embodiment, the second magnetic attraction part 40 includes: a bracket 41, which is movably arranged; a magnetic attraction member 42, which is arranged on the bracket 41, and the magnetic attraction member 42 cooperates with the first magnetic attraction part 30; an iron core 43, which is connected to the bracket 41, and the iron core 43 cooperates with the electromagnet 50. The power on and off of the electromagnet 50, and the cooperation with the reset elastic member 60, can drive the iron core 43 to move, and the iron core 43 drives the bracket 41 and the magnetic attraction member 42 to move, and then the magnetic attraction member 42 attracts the first magnetic attraction part 30 or releases the first magnetic attraction part 30. Specifically, the magnetic attraction member 42 is a magnet.

[0030] Optionally, the electromagnet 50 has a guide groove, a part of the iron core 43 penetrates into the guide groove, and the iron core 43 can slide in the guide groove, so that the iron core 43 can move in a preset direction and move smoothly. The extension direction of the guide groove is perpendicular to the axis of the valve body 10.

[0031] Optionally, the second magnetic attraction portion 40 further includes a limiting member, which is disposed on the iron core 43 , and the bracket 41 has a limiting groove, and the limiting member is inserted into the limiting groove, thereby fixing the iron core 43 and the bracket 41 in connection.

[0032] In this embodiment, the rotating structure 20 includes: a rotating shaft 21, which is rotatably disposed on the inner wall of the channel 11; a baffle 22, which is disposed on the rotating shaft 21, and a first magnetic attraction portion 30 is disposed on the baffle 22. Specifically, the first magnetic attraction portion 30 is disposed on the edge of the baffle 22. The baffle 22 can be set as a circular plate, and the rotation of the baffle 22 can achieve a change in the minimum flow area.

[0033] In this embodiment, the valve body 10 includes: a cylinder 13, the channel 11 is located in the cylinder 13; a cover 14, the cover 14 and the cylinder 13 are detachably connected, and the gas outlet 12 is located on the cover 14. This facilitates the assembly of the steam valve. There are multiple gas outlets 12, which can prevent the gas outlet 12 from being too large and causing impurities to enter.

[0034] In another embodiment not shown, the driving structure further includes: a motor, which is drivingly connected to the second magnetic attraction portion 40 to move the second magnetic attraction portion 40 to the attraction position or the release position, that is, the electromagnet 50 is replaced by the motor.

[0035] Another embodiment of the present invention provides a cooking utensil, comprising the above-mentioned steam valve. With this solution, the driving structure and the first magnetic attraction portion 30 cooperate to drive the rotating structure 20 to rotate, thereby adjusting the minimum flow area in the valve body 10, which can also be understood as adjusting the steam discharge volume. With this solution, the minimum flow area can be adjusted according to the heating power of the cooking utensil, thereby avoiding overflow and ensuring the energy efficiency of the cooking utensil.

[0036] Specifically, the cooking appliance further comprises a pot body, an upper cover, a heating unit and a control unit, wherein the heating unit is arranged in the pot body, the steam valve is arranged on the upper cover, the inlet of the steam valve is connected to the cavity of the pot body, and the heating unit and the steam valve are both electrically connected to the control unit, so that the cooking appliance can be automatically controlled.

[0037] Furthermore, the cooking utensil is an electric rice cooker, and the heating power of the heating unit is adjustable. When the heating unit adjusts the power, the control unit controls the rotating structure 20 of the steam valve to move accordingly, thereby avoiding overflow and ensuring the energy efficiency of the cooking utensil.

[0038] Due to the use of the steam valve with a variable steam channel of the present invention, the size of the steam channel can be adjusted as needed during the cooking process to ensure that a large steam channel is used when cooking with high heat to ensure that the rice slurry in the pot does not overflow, and a small steam channel is used when cooking with low heat to ensure that the energy efficiency of the entire machine is not reduced.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
