Description

Technical Field

[0001] This utility model relates to the field of stove technology, and in particular to a gas valve and stove. Background Technology

[0002] In the field of gas stoves, gas stoves supply gas to the burner through a gas valve. This gas valve typically includes a stopcock, an inner ring gas passage, and an outer ring gas passage. Users adjust the gas flow into the inner and outer ring gas passages by rotating the stopcock. Currently, due to improved living standards, people have more diverse requirements for burner heat control modes. A stopcock alone cannot meet these demands. Existing technologies often include an additional regulating valve to add functional modes, such as a uniform flame or a high-heat stir-fry mode. However, in existing technologies, the regulating valve is usually installed on one side of the gas valve. This increases the overall size of the gas valve, making it less compact, occupying too much space, and causing installation inconvenience. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of existing gas valves for stoves, which are too large, not compact enough, and occupy too much space after adding a regulating valve, and to provide a gas valve and stove.

[0004] The present invention solves the above-mentioned technical problems through the following technical solution:

[0005] This utility model provides a gas valve, which includes an inner ring gas passage, an outer ring gas passage, and a regulating valve;

[0006] The inner ring gas passage and the outer ring gas passage are at least partially parallel and spaced apart, the regulating valve is located between the inner ring gas passage and the outer ring gas passage, and the length direction of the regulating valve is parallel to the extension direction of the inner ring gas passage;

[0007] The regulating valve includes a first valve body and a first valve core. The first valve body is provided with a first valve cavity, a first valve channel and a second valve channel. The first valve channel connects the outer ring gas channel and the first valve cavity, and the second valve channel connects the inner ring gas channel and the first valve cavity. The first valve core can move within the first valve cavity to connect or disconnect the first valve channel and the second valve channel.

[0008] The first valve passage and the second valve passage extend horizontally, and the central axes of the inner ring gas passage, the outer ring gas passage, the first valve passage, and the second valve passage are located on the same horizontal plane.

[0009] In this design, the regulating valve moves within the first valve chamber via a first valve core to connect or disconnect the first and second valve channels, allowing gas flow or interruption in the inner and outer ring gas channels. This regulates the flame intensity of the inner and outer rings, increasing the valve's flame intensity adjustment modes and making its functions more diverse. By arranging the inner and outer ring gas channels parallel and spaced apart, and placing the regulating valve between them with its length parallel to the extension direction of the inner ring gas channel, the space between the two channels is fully utilized, resulting in a more compact overall structure and preventing the valve from becoming too large. Furthermore, by extending the first and second valve channels horizontally, the central axes of the inner and outer ring gas channels are located on the same horizontal plane, preventing an increase in the overall height of the valve and further enhancing its compactness and reducing its size.

[0010] Preferably, the outer ring gas passage includes a first outer ring passage and a second outer ring passage, the first outer ring passage and the second outer ring passage are connected, the first outer ring passage and the second outer ring passage are perpendicular to each other, and the second outer ring passage is parallel to the inner ring gas passage.

[0011] In this design, the outer ring gas passage includes two parts: a first outer ring passage and a second outer ring passage. By vertically setting the first outer ring passage and the second outer ring passage, the first outer ring passage, the second outer ring passage, and the inner ring gas passage together enclose an area for setting the regulating valve. The vertical setting also makes the overall structure of the gas valve more compact.

[0012] Preferably, the extension direction of the first valve chamber is parallel to the extension direction of the inner ring gas passage, and the first valve core can move along the extension direction of the first valve chamber to connect or disconnect the first valve passage and the second valve passage. The first valve passage is located at one end of the first valve body near the first outer ring passage, and the second valve passage is located on the side of the first valve body near the inner ring gas passage.

[0013] In this design, by aligning the extension direction of the first valve chamber with the extension direction of the inner ring gas passage, the first valve core can move along the extension direction of the first valve chamber. This allows the first valve chamber and the first valve core to fully utilize the elongated space between the outer ring gas passage and the inner ring gas passage. Furthermore, by placing the first valve passage at one end of the first valve body near the first outer ring passage and the second valve passage on one side of the first valve body, the lengths of both the first and second valve passages are shortened, eliminating the need for complex passages and resulting in a more compact overall structure for the gas valve.

[0014] Preferably, the gas valve has clearance notches on both sides in the width direction, and a portion of the inner ring gas passage and the second outer ring passage are located within the clearance notches.

[0015] In this design, by providing clearance notches on both sides of the gas valve in the width direction, and placing portions of the inner ring gas passage and the second outer ring passage within the clearance notches, the length of the gas valve in the width direction can be reduced, making the overall structure of the gas valve more compact and further reducing the overall volume of the gas valve.

[0016] Preferably, the gas valve further includes a plug valve, which includes a second valve body. The second valve body has a second valve chamber for connecting to a gas pipeline. The second valve body has an inner ring outlet and an outer ring outlet that connect to the second valve chamber. The inner ring outlet connects to the inlet of the inner ring gas passage, and the outer ring outlet connects to the inlet of the outer ring gas passage.

[0017] In this design, gas enters the second valve chamber of the stopcock valve through a gas pipeline, then flows out through the inner and outer ring outlets of the second valve chamber, and subsequently into the inner and outer ring gas passages. Since the outer ring gas passage typically contains more gas, when the regulating valve is opened, the outer ring gas passage can flow into the inner ring gas passage, increasing the amount of gas flowing into the inner ring. This activates the inner ring stir-fry mode, making it suitable for more cooking scenarios and improving the user's cooking experience and ease of operation.

[0018] Preferably, the plug valve further includes a second valve core, which is disposed in the second valve cavity and can rotate relative to the second valve body about the axial direction of the second valve core. The second valve core is provided with a plurality of inner ring holes and outer ring holes of different diameters in its circumferential direction. The positions of the plurality of inner ring holes and the inner ring air outlets correspond in the axial direction of the second valve core, and the positions of the plurality of outer ring holes and the outer ring air outlets correspond in the axial direction of the second valve core.

[0019] In this solution, by rotating the second valve core, the inner ring holes of different diameters are aligned with the inner ring gas outlet, and the outer ring holes of different diameters are aligned with the outer ring gas outlet. The inner and outer ring holes of different diameters will provide different amounts of gas to the inner and outer ring gas passages, thereby adjusting the firepower of the inner and outer ring burner caps. This makes it suitable for more cooking scenarios and improves the user's cooking experience and ease of operation.

[0020] Preferably, the gas valve further includes a plug valve, which includes a second valve body. The second valve body has a second valve chamber for connecting to a gas pipeline. The second valve body has an inner ring outlet that connects to the second valve chamber. The inner ring outlet connects to the inlet of the inner ring gas passage. The second valve chamber is not connected to the outer ring gas passage.

[0021] In this design, the second valve chamber is not connected to the outer ring gas passage; the gas for the outer ring gas passage is supplied through the inner ring gas passage. When the regulating valve is closed, only the inner ring has flame, allowing for independent adjustment of the inner ring's flame intensity. When the regulating valve is open, the inner and outer ring gas passages are connected, enabling simultaneous synchronous flame adjustment of both rings. This makes the design suitable for a wider range of cooking scenarios, enhancing the user's cooking experience and operational convenience.

[0022] Preferably, the gas valve further includes a connector, which is fixed between the outer ring gas passage and the inner ring gas passage, and the regulating valve is threadedly connected to the connector.

[0023] In this design, the control valve is connected to the connector using a threaded connection, which makes it easier to install and disassemble the control valve, and facilitates its later maintenance and replacement.

[0024] Preferably, the regulating valve is a suction valve or a solenoid valve.

[0025] This utility model also provides a stove, wherein the stove burner includes the gas valve described above.

[0026] The positive and progressive effects of this utility model are as follows:

[0027] The regulating valve moves within the first valve chamber via a first valve core to connect or disconnect the first and second valve channels, allowing gas flow in the inner and outer ring gas channels or cutting them off, thereby regulating the flame intensity of the inner and outer rings. This increases the flame intensity regulation modes of the gas valve, making its functions more diverse. By arranging the inner and outer ring gas channels parallel and spaced apart, and placing the regulating valve between them with its length parallel to the extension direction of the inner ring gas channel, the space between the inner and outer ring gas channels can be fully utilized, resulting in a more compact overall structure and preventing the gas valve from becoming too large. Furthermore, by extending the first and second valve channels horizontally, the central axes of the inner and outer ring gas channels, as well as the first and second valve channels, are located on the same horizontal plane, preventing an increase in the overall height of the gas valve, further enhancing its compactness and reducing its size.

[0055] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the following embodiments.

[0056] Example 1

[0057] like Figure 1 As shown, this embodiment provides a stove 100, which includes a gas valve 110.

[0058] like Figures 2-5 As shown, the gas valve 110 includes an inner ring gas passage 300, an outer ring gas passage 400, and a regulating valve 200. At least a portion of the inner ring gas passage 300 and the outer ring gas passage 400 are arranged parallel to each other and spaced apart. The regulating valve 200 is located between the inner ring gas passage 300 and the outer ring gas passage 400, and the length direction of the regulating valve 200 is parallel to the extension direction of the inner ring gas passage 300. The regulating valve 200 includes a first valve body 210 and a first valve core 220. The first valve body 210 has a first valve cavity 230, a first valve passage 240, and a second valve passage 250. The first valve passage 240 connects the outer ring gas passage 400 and the first valve cavity 230, and the second valve passage 250 connects the inner ring gas passage 300 and the first valve cavity 230. The first valve core 220 is movable within the first valve cavity 230 to connect or disconnect the first valve passage 240 and the second valve passage 250. The first valve passage 240 and the second valve passage 250 extend horizontally, and the central axes of the inner ring gas passage 300, the outer ring gas passage 400, the first valve passage 240, and the second valve passage 250 are located on the same horizontal plane.

[0059] The regulating valve 200 moves within the first valve chamber 230 via the first valve core 220 to connect or disconnect the first valve passage 240 and the second valve passage 250, allowing gas to flow or be cut off in the inner ring gas passage 300 and the outer ring gas passage 400, thereby regulating the flame intensity of the inner and outer rings. This increases the flame intensity regulation modes of the gas valve 110, making its functions more diverse. By arranging the inner ring gas passage 300 and the outer ring gas passage 400 in parallel intervals, and placing the regulating valve 200 between them, with its length parallel to the extension direction of the inner ring gas passage 300, the space between the inner ring gas passage 300 and the outer ring gas passage 400 can be fully utilized, making the overall structure of the gas valve 110 more compact and preventing it from becoming too large. Meanwhile, by extending the first valve channel 240 and the second valve channel 250 in the horizontal direction, the central axes of the inner ring gas channel 300, the outer ring gas channel 400, the first valve channel 240, and the second valve channel 250 are located on the same horizontal plane, thereby avoiding an increase in the overall height of the gas valve 110, making the structure more compact, and reducing the volume of the gas valve 110.

[0060] The outer ring gas passage 400 includes a first outer ring passage 410 and a second outer ring passage 420, which are connected. The first outer ring passage 410 and the second outer ring passage 420 are perpendicular to each other, and the second outer ring passage 420 is parallel to the inner ring gas passage 300. By perpendicularly arranging the first outer ring passage 410 and the second outer ring passage 420, the first outer ring passage 410, the second outer ring passage 420, and the inner ring gas passage 300 together enclose an area for housing the regulating valve 200, and the vertical arrangement makes the overall structure of the gas valve 110 more compact. In other embodiments, other specific structures of the outer ring gas passage 400 that are deemed suitable by those skilled in the art may also be used.

[0061] The first valve chamber 230 extends parallel to the extension direction of the inner ring gas passage 300. The first valve core 220 can move along the extension direction of the first valve chamber 230 to connect or disconnect the first valve passage 240 and the second valve passage 250. The first valve passage 240 is located at one end of the first valve body 210 near the first outer ring passage 410, and the second valve passage 250 is located on the side of the first valve body 210 near the inner ring gas passage 300. By making the extension direction of the first valve chamber 230 parallel to the extension direction of the inner ring gas passage 300, and by allowing the first valve core 220 to move along the extension direction of the first valve chamber 230, the first valve chamber 230 and the first valve core 220 can fully utilize the elongated space between the outer ring gas passage 400 and the inner ring gas passage 300. Furthermore, by placing the first valve channel 240 at one end of the first valve body 210 near the first outer ring channel 410, and the second valve channel 250 on one side of the first valve body 210, the lengths of the first valve channel 240 and the second valve channel 250 are relatively short, eliminating the need for complex channels and making the overall structure of the gas valve 110 more compact.

[0062] like Figure 2 As shown, the gas valve 110 has clearance notches 260 on both sides in the width direction, and portions of the inner ring gas passage 300 and the second outer ring passage 420 are located within the clearance notches 260. By providing clearance notches 260 on both sides in the width direction of the gas valve 110, and placing portions of the inner ring gas passage 300 and the second outer ring passage 420 within the clearance notches 260, the length of the gas valve 110 in the width direction can be reduced, making the overall structure of the gas valve 110 more compact and further reducing the overall volume of the gas valve 110.

[0063] like Figures 3-5As shown, the gas valve 110 also includes a plug valve 500. The plug valve 500 includes a second valve body 510. The second valve body 510 has a second valve chamber 520 inside. The second valve chamber 520 is used to connect to the gas pipeline. The second valve body 510 has an inner ring gas outlet and an outer ring gas outlet that connect to the second valve chamber 520. The inner ring gas outlet connects to the gas inlet of the inner ring gas passage 300, and the outer ring gas outlet connects to the gas inlet of the outer ring gas passage 400.

[0064] Gas enters the second valve chamber 520 of the stopcock valve 500 through the gas pipeline, and then flows out through the inner and outer ring outlets of the second valve chamber 520, subsequently flowing into the inner ring gas passage 300 and the outer ring gas passage 400. Since the outer ring gas passage 400 usually contains more gas, when the regulating valve 200 is opened, the gas can flow from the outer ring gas passage 400 into the inner ring gas passage 300, increasing the amount of gas flowing into the inner ring, thereby activating the inner ring stir-fry mode, which is suitable for more cooking scenarios and improves the user's cooking experience and ease of operation.

[0065] The stopcock valve 500 also includes a second valve core 530, which is located within the second valve cavity 520 and can rotate relative to the second valve body 510 about its axial direction. The second valve core 530 has multiple inner ring holes 531 and outer ring holes 532 of different diameters in its circumferential direction. The multiple inner ring holes 531 and the inner ring gas outlet correspond to each other in the axial direction of the second valve core 530, and the multiple outer ring holes 532 and the outer ring gas outlet correspond to each other in the axial direction of the second valve core 530. By rotating the second valve core 530, the inner ring holes 531 of different diameters align with the inner ring gas outlet, and the outer ring holes 532 of different diameters align with the outer ring gas outlet. The inner ring holes 531 and outer ring holes 532 of different diameters provide different amounts of gas to the inner ring gas passage 300 and the outer ring gas passage 400, thereby adjusting the flame of the inner and outer ring burners. This makes it suitable for more cooking scenarios and improves the user's cooking experience and operational convenience.

[0066] The gas valve 110 also includes a connector 600, which is fixed between the outer ring gas passage 400 and the inner ring gas passage 300. The regulating valve 200 is threadedly connected to the connector 600. The threaded connection of the regulating valve 200 to the connector 600 makes it easier to install and remove the regulating valve 200, and facilitates its later maintenance and replacement.

[0067] The regulating valve 200 is a forced suction valve or a solenoid valve, or other specific valve types that are deemed appropriate by those skilled in the art.

[0068] The cooktop 100 has an intelligent voice control module, which includes a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the cooktop 100 to perform corresponding operations, thereby realizing the intelligent control of the cooktop 100 and improving the user experience of using this intelligent appliance.

[0069] Example 2

[0070] The structure of this embodiment is basically the same as that of embodiment 1, and the same structure will not be described in detail. The difference is that:

[0071] like Figure 6 As shown, in this embodiment, the second valve chamber 520 is not connected to the outer ring gas passage 400. Since the second valve chamber 520 is not connected to the outer ring gas passage 400, the gas in the outer ring gas passage 400 is supplied through the inner ring gas passage 300. When the regulating valve 200 is closed, only the inner ring has flame, allowing for independent adjustment of the inner ring's flame intensity. When the regulating valve 200 is open, the inner ring gas passage 300 and the outer ring gas passage 400 are connected, allowing for simultaneous synchronous flame adjustment of both the inner and outer rings. This makes it suitable for more cooking scenarios and improves the user's cooking experience and operational convenience.
