Detailed Embodiments
[0029] In order to make the technical problems to be solved, technical solutions and beneficial technical effects of the present application clearer and more understandable, the present application will be further described in detail below in conjunction with the accompanying drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the protection scope of the present application.
[0030] Figure 1 and Figure 2 FIGS. and
[0031] respectively show an example of a cock valve of a gas stove in a perspective view and a sectional view. The cock valve includes a valve body 1 and a valve core 2. Among them, the valve body 1 is formed with a receiving cavity, and the valve core 2 is rotatably disposed in the receiving cavity. The valve body 1 is provided with an air outlet passage 10, and the air outlet passage 10 is connected to the gas passage 3 of the gas stove for transmitting gas to the burner. The valve core 2 is provided with an air inlet 21 and an air outlet 22, and the air outlet 22 can be communicated with or blocked from the air outlet passage 10 to realize the on-off of the gas. After the gas enters the valve core 2 through the air inlet 21, the size of the gas flux can be controlled by adjusting the area where the air outlet 22 is communicated with the air outlet passage 10, thereby realizing the adjustment of the firepower. It should be noted that in the present application, the "communicated area" refers to the area where the corresponding air outlet 22 coincides with the air outlet passage 10 along the radial direction of the valve core.
[0031] In existing gas stoves, especially those with a large heat load, in order to achieve a large firepower, it is usually necessary to make the apertures of the air outlet 22 and the air outlet passage 10 larger to ensure a sufficiently large communication area. However, this also brings the problem that the communication area changes too much when the valve core 2 rotates by a certain angle, and fine adjustment cannot be achieved. This problem is particularly obvious when the fire is small.
[0032] For this reason, in the cock valve of the present application, the valve body 1 and the valve core 2 are respectively provided with a plurality of air outlet passages 10 and a plurality of air outlets 22. Among them, the plurality of air outlet passages 10 include a first air outlet passage 11 and a second air outlet passage 12. Both the first air outlet passage 11 and the second air outlet passage 12 are connected to the gas passage 3 of the same ring of the gas stove. Thus, the structure in which one air outlet passage 10 corresponds to one gas passage 3 of the same ring in the original cock valve is changed, so that the gas of the same ring can be jointly supplied by two air outlet passages 10. Under the condition of ensuring the same heat load, the aperture of each air outlet passage 10 can be made smaller than that of the original cock valve.
[0033] The plurality of air outlets 22 include a first air outlet 221 and a second air outlet 222.
[0034] The valve core 2 includes a first position and a second position. When the valve core 2 is in the first position, the first air outlet 221 and the second air outlet 222 are respectively communicated with the first air outlet passage 11 and the second air outlet passage 12. Thus, there is gas in both air outlet passages 10 that can be transmitted to the gas passage 3, and the apertures of the first air outlet 221 and the first air outlet passage 11 can be made smaller while ensuring the high firepower of the gas stove; when the valve core 2 is in the second position, the first air outlet 221 is communicated with the first air outlet passage 11 and the second air outlet 222 is cut off from the second air outlet passage 12. At this time, the valve core 2 rotates by a certain angle, and only the area where the first air outlet 221 is connected to the first air outlet passage 11 changes. Compared with the original cock valve, the change in gas flux is smaller, and it is easier for users to finely adjust the low fire. Therefore, while ensuring high firepower, precise control of the low fire is achieved.
[0035] According to an exemplary embodiment of the present application, as Figure 2 shown, the first air outlet 221 and the second air outlet 222 are vertically offset and opened on the side surface of the valve core 2. The air outlets 22 being provided at different heights is beneficial to preventing the communication between the non-matching air outlets 22 and the air outlet passages 10 during the rotation of the valve core 2.
[0036] Furthermore, the first air outlet passage 11 is opened at a position of the valve body 1 at the same height as the first air outlet 221, and the second air outlet passage 12 is opened at a position of the valve body 1 at the same height as the second air outlet 222, so that the corresponding air outlets 22 and the air outlet passages 10 are smoothly communicated.
[0037] Figure 3 and Figure 4 Figure shows a cross-sectional view schematically showing the cross-section at the height where the second air outlet 222 is located when the valve core 2 is in the first position. As Figure 4 shown, the second air outlet passage 12 includes a first segment 121 and a second segment 122 that are communicated with each other. Among them, the first segment 121 is coaxially communicated with the second air outlet 222, which is beneficial for the gas to flow smoothly into the first segment 121. The second segment 122 is used to guide the gas to pass through and enter the gas passage 3. The gas flow path is as shown by the arrow in Figure 4 . It can be understood that a certain angle is formed between the first segment 121 and the second segment 122 to achieve the guidance of the gas direction. In other examples, the second air outlet passage 12 can also be a complete zigzag passage to guide the gas into the gas passage 3, which will not be elaborated here.
[0038] Figure 5 and Figure 6 Figure shows a cross-sectional view schematically showing the cross-section at the height where the first air outlet 221 is located when the valve core 2 is in the second position. At this time, the gas only flows through the first air outlet 221 and the first air outlet passage 11 to the gas passage 3. The gas flow path is asFigure 6 as shown by the arrow. Compared with the first position, the gas stove is in a relatively low-firepower stage.
[0039] The valve core 1 further includes a third position. When the valve core 2 rotates from the second position to the third position, the area of the first air outlet 221 communicating with the first air outlet passage 11 gradually becomes smaller until it is blocked, and at this time the gas stove is in a closed state.
[0040] Further, the first air outlet 221 includes a communicating air hole 221a and an air outlet groove 221b. When the valve core 2 rotates from the first position to the second position, the area of the air hole 221a communicating with the first air outlet passage 11 gradually becomes smaller, and the area of the air outlet groove 221b communicating with the first air outlet passage 11 gradually becomes larger, and the gas stove changes from high firepower to low firepower.
[0041] When the valve core 2 rotates from the second position to the third position, the area of the air outlet groove 221b communicating with the first air outlet passage 11 becomes smaller until it is blocked. In this stage, the gas stove is in a low-fire state, which is easy to achieve precise adjustment of the low fire.
[0042] According to an exemplary embodiment of the present application, as Figure 2 shown, the plurality of air outlet passages 10 further includes a third air outlet passage 13, and the gas pipeline 3' communicated with the third air outlet passage 13 is different from the gas passage 3 communicated with the first air outlet passage 11 and the second air outlet passage 12. In one example, the gas pipeline 3' leads to the inner ring of the burner, and the gas passage 3 leads to the outer ring of the burner. In addition, the plurality of air outlets 22 on the valve core 2 includes a third air outlet 223 that can communicate with the third air outlet passage 13.
[0043] According to an exemplary embodiment of the present application, when the valve core 2 is in the first position, the area of the plurality of air outlet passages 10 communicating with the plurality of air outlets 22 is the largest. Taking the gas pipeline 3' and the gas passage 3 leading to the inner ring and the outer ring of the burner respectively as an example, at this time both the inner ring and the outer ring are in a high-firepower state.
[0044] The present application also proposes an embodiment of a gas stove, and the gas stove includes the cock valve of the above gas stove.
[0045] According to an exemplary embodiment of the present application, the gas stove has a burner with at least one ring of fire holes, and the number of rings of the fire holes is equal to the number of gas passages 3.
[0046] The components of different embodiments can be combined with each other in any feasible way to achieve the purpose of the present application.
[0047] It should be noted that this application should not be construed as limited to the embodiments described above, but should be understood to cover all possible embodiments determined by the combination of the claims of this application and the content disclosed in the specification. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this application without departing from the technical solution of this application all fall within the protection scope of the technical solution of this application.
