[0051] Gas stoves are a common kitchen appliance in daily households. When stir-frying food, there are higher requirements for the firepower of gas stoves, which need to provide enough firepower to achieve the stir-frying function. Based on this, users have higher requirements for the heating efficiency of gas stoves to meet the firepower requirements under different cooking conditions.

[0052] In the related art, the heating efficiency of the gas stove has been improved in different ways.

[0053] In some related technologies, a ring of gas mixing chamber is added to the burner head of the burner on the basis of the original structure, and an ejector tube and a nozzle are added accordingly. During normal cooking, the newly added ejector tube and nozzle are not turned on, and the burner works normally. When the stir-fry function is required, the newly added ejector tube and nozzle are turned on, and the burner adds a ring of flame to increase the firepower.

[0054] However, the above solution requires adding a ring of mixing chambers to the burner, which will make the burner and the fire cover larger and the structure more complicated. When the size of the burner remains unchanged, adding a ring of mixing chambers will reduce the size of the original mixing chamber, thereby increasing the air outlet resistance and affecting the combustion efficiency.

[0055] In other related technologies, the burner of the gas stove has a double nozzle structure, and multiple nozzles are arranged on an ejector pipe. During normal cooking, a single nozzle on the ejector pipe is opened to eject gas. When the stir-fry function is required, multiple nozzles on the ejector pipe are opened to eject gas together, increasing the amount of gas introduced, thereby improving the combustion effect.

[0056] However, the above solution requires arranging multiple nozzles on the ejector tube, and the multiple nozzles will inevitably be eccentric with the ejector tube, resulting in poor ejection effect. In this way, during normal cooking, the state of the nozzles being introduced into the ejector tube will be poor. During stir-frying, the gas ejected from the multiple nozzles will also interfere with each other, causing the introduced airflow to be chaotic and affecting the combustion effect.

[0057] In other related technologies, a cut-off hole is provided in front of the nozzle of the gas stove. In the normal cooking process, the nozzle cuts off the flow through the cut-off hole, and in the process of stir-frying, the cut-off hole of the nozzle does not cut off the flow.

[0058] The above scheme will cause the pressure of gas introduced by the nozzle to be low during normal cooking of the gas stove, and the injection effect will be correspondingly poor. The combustion effect during the use of the gas stove will be poor, which may easily lead to incomplete combustion and the generation of harmful gases.

[0059] In some related technologies, in order to realize the stir-fry function, the valve body of the gas stove has separate outer ring air duct and inner ring air duct to supply air to the outer ring and the inner ring. The stir-fry air duct is often connected with the outer ring air duct or the inner ring air duct. When the stir-fry function is started, the stir-fry air duct opens, but this control method can only reduce the firepower on the original gas valve, and cannot increase the firepower, and cannot realize the stir-fry function of the stove.

[0060] Based on this, the present application provides a gas stove, such as Figure 1 As shown, Figure 1The present invention provides a schematic diagram of a gas stove 100. The gas stove 100 includes a housing 11, which forms an installation cavity 10 with an opening. The opening is connected to the installation cavity 10, so that other relevant components of the gas stove 100 can be installed in the installation cavity 10 of the housing 11. The housing 11 can provide support for the relevant components installed in the installation cavity 10 thereof, as well as a certain degree of protection, to ensure that the gas stove 100 can work normally.

[0061] On this basis, see Figure 1 The gas stove 100 provided in the embodiment of the present application further includes a burner 2. The burner 2 is the core component of the gas stove 100, and the burner 2 includes a burner head 21, which is disposed in the mounting cavity 10 of the housing 11. The burner head 21 can make the fuel and the primary air mixed in a certain manner, and the primary air and fuel mixed in the burner head 21 flow out from the fire outlet hole of the fire cover provided on the burner head 21, and are ignited to form a flame, which heats the bottom of the pot for the user to cook.

[0062] Continue to see Figure 1 The gas stove 100 provided in the present application further includes a panel 12, which is covered on the opening of the housing 11 and is used to cover the mounting cavity 10 of the housing 11. In this way, the panel 12 can prevent debris or food residues dropped during cooking from falling into the mounting cavity 10 of the housing 11, thereby ensuring that other components arranged in the mounting cavity 10 are not damaged or contaminated, and further ensuring that the gas stove 100 can work normally.

[0063] In this case, if Figure 1 As shown, the panel 12 is also provided with an escape opening 120. The burner head 21 is arranged opposite to the escape opening 120 provided on the panel 12, so that the burner head 21 can be located within the opening range of the escape opening 120 of the panel 12. In this way, when the burner 2 burns fuel to generate flames, the panel 12 will not block the flames generated by the burner 2 burning fuel, ensuring that the burner 2 can work normally, so that the flames can heat the bottom of the pot, so that the user can cook.

[0064] like Figure 2 As shown, Figure 2 This is a schematic diagram of the structure of a burner 2 provided in an embodiment of the present application. The burner 2 may further include a fire cover assembly 22, a first ejector pipe 23, a second ejector pipe 24 and a central ejector assembly 25.

[0065] In order to increase the firepower of burner 2, Figure 3 As shown, Figure 3 for Figure 2As shown in the partial structural diagram of the burner 2, the burner head 21 may be provided with a central fire channel 211 penetrating the burner head 21, and having a first gas mixing chamber 212 and a second gas mixing chamber 213 with openings sequentially surrounding the periphery of the central fire channel 211.

[0066] The central fire channel 211, the first gas mixing chamber 212 and the second gas mixing chamber 213 can be used to circulate gas. In this way, gas can flow through the central fire channel 211, the first gas mixing chamber 212 and the second gas mixing chamber 213, and the firepower of the burner 2 is greater. At the same time, the central fire channel 211 is formed by the original air circulation space in the middle of the burner head 21, and there is no need to additionally compress the annular chamber of the burner head 21, and the overall size of the burner head 21 can also be guaranteed.

[0067] like Figure 2 As shown, the fire cover assembly 22 can be covered on the burner head 21 and has a central fire channel 211 ( Figure 3 )、the first gas mixing chamber 212( Figure 3 ) and the second gas mixing chamber 213 ( Figure 3 ) are connected to a plurality of fire outlet holes 221.

[0068] In this way, the mixed gas in the central fire channel 211 , the first gas mixing chamber 212 and the second gas mixing chamber 213 can flow out through the gas outlet fire hole 221 on the fire cover assembly 22 and be ignited.

[0069] It can be understood that the above-mentioned fire cover assembly 22 is provided with multiple air outlet fire holes 221 connected with the central fire channel 211, the first air mixing chamber 212 and the second air mixing chamber 213, which means that the central fire channel 211, the first air mixing chamber 212 and the second air mixing chamber 213 can all be connected with a part of the air outlet fire holes 221.

[0070] In order to transport gas to the central fire channel 211, the first gas mixing chamber 212 and the second gas mixing chamber 213, one end of the first ejector pipe 23 can be connected to the first gas mixing chamber 212, and one end of the second ejector pipe 24 can be connected to the second gas mixing chamber 213. In this way, the first ejector pipe 23 and the second ejector pipe 24 can transport gas to the first gas mixing chamber 212 and the second gas mixing chamber 213 respectively.

[0071] For example, Figure 4 As shown, Figure 4 for Figure 3 The structure diagram of the burner head 21 shown in FIG. 2 shows a first gas mixing inlet 214 and a second gas mixing inlet 215. The first gas mixing inlet 214 is connected to the first gas mixing chamber 212, and the second gas mixing inlet 215 is connected to the second gas mixing chamber 213. The first gas mixing inlet 214 can be connected to the first ejector tube 23 ( Figure 3) is connected to one end of the second gas mixture inlet 215, and the second ejector tube 24 ( Figure 3 ) at one end.

[0072] It can be understood that the other ends of the first ejector tube 23 and the second ejector tube 24 can be connected to the gas pipeline, and the gas can be transported into the first ejector tube 23 and the second ejector tube 24 through the gas pipeline, and then delivered to the first mixing chamber 212 and the second mixing chamber 213 through the first ejector tube 23 and the second ejector tube 24.

[0073] In addition, if Figure 3 As shown, the burner 2 may further include a first nozzle 26 and a second nozzle 27. The first nozzle 26 is disposed at one end of the first ejector pipe 23 away from the burner head 21, and the second nozzle 27 is disposed at one end of the second ejector pipe 24 away from the burner head 21. A gas pipeline may be connected to the first nozzle 26 and the second nozzle 27.

[0074] In this way, when the gas pipeline is transporting gas, the gas can be ejected from the first nozzle 26 and the second nozzle 27. At the same time, the gas flow ejected from the first nozzle 26 and the second nozzle 27 is relatively fast, which can drive the surrounding air to be sucked into the first ejector pipe 23 and the second ejector pipe 24. In this way, the gas and air can be mixed in the first gas mixing chamber 212 and the second gas mixing chamber 213.

[0075] It is understandable that, in order to ensure the setting effect of the first nozzle 26 and the second nozzle 27, the first nozzle 26 can be arranged concentrically with the first ejection tube 23, and the second nozzle 27 can be arranged concentrically with the second ejection tube 24. In this way, the first nozzle 26 and the second nozzle 27 can ensure the ejection effect when working.

[0076] In addition, since the first nozzle 26 and the second nozzle 27 are respectively disposed in the first ejector tube 23 and the second ejector tube 24, the airflows in the first ejector tube 23 and the second ejector tube 24 are independent of each other and will not affect each other.

[0077] In addition, in order to reduce the number of ejector tubes, such as Figure 2 As shown, the burner 2 provided in the embodiment of the present application further includes a central ejection assembly 25. The central ejection assembly 25 is arranged on a side of the burner head 21 away from the fire cover assembly 22 and is connected to the burner head 21. Figure 5 As shown, Figure 5 The schematic diagram of the structure of a central ejection assembly 25 provided in an embodiment of the present application, wherein the central ejection assembly 25 has a central air inlet 251 and a central air outlet 252. The central air outlet 252 faces the central fire channel 211 ( Figure 4 ), the central air inlet 251 can be used to communicate with the gas pipeline.

[0078] In this way, the burner 2 provided in the embodiment of the present application has a central fire channel 211 formed in the center of the burner head 21, and the central air outlet 252 of the central ejection assembly 25 can transport gas toward the central fire channel 211, so that the central fire channel 211 can further enhance the firepower of the burner 2 and realize high-firepower operation of the burner 2.

[0079] At the same time, by means of the central fire channel 211 of the burner head 21 and by using the central ejector assembly 25 to transport gas to the central fire channel 211, the burner head 21 does not need to add a new annular gas mixing chamber, and the central ejector assembly 25 can be directly set to deliver gas without adding a new ejector pipe for connection. Therefore, the burner 2 provided in the embodiment of the present application can reduce the number of ejector pipes of the burner 2 as a whole while ensuring the combustion efficiency, reduce the components of the burner 2, and simplify the composition structure of the burner 2.

[0080] As mentioned above, the central air inlet 251 can be connected to the gas pipeline. Generally, along the axial direction of the central fire channel 211, the space on the side of the burner 21 away from the fire cover assembly 22 is small, which is inconvenient to arrange the pipeline.

[0081] In order to facilitate the setting of the gas pipeline, in some embodiments, as Figure 6 As shown, Figure 6 A schematic diagram of the structure of a burner 2 provided in an embodiment of the present application at another angle, wherein the central air inlet 251 can be oriented in the radial direction of the central fire channel 211. In this way, when the gas pipeline is connected to the central ejection assembly 25, the gas pipeline can be connected in the radial direction of the central fire channel 211, which makes the connection more convenient and the spatial arrangement more reasonable.

[0082] In some embodiments, Figure 5 As shown, the central ejection assembly 25 may include a central ejection joint 253 and a central nozzle 254. The central ejection joint 253 is disposed on the burner head 21. One end of the central ejection joint 253 has a central air inlet 251, and the central nozzle 254 is connected to the other end of the central ejection joint 253 and has a central air outlet 252. In this way, the gas can enter the interior of the central ejection joint 253 through the central air inlet 251, and flow into the central fire channel 211 through the central air outlet 252.

[0083] At the same time, the central nozzle 254 can be installed and fixed through the central injection joint 253. At the same time, the high-speed gas ejected from the central nozzle 254 can drive the surrounding air into the central fire channel 211 to complete the mixing of gas and air, so that the gas can be smoothly ignited and burned.

[0084] Exemplarily, the central ejection joint 253 can be detachably connected to the central nozzle 254. The central nozzle 254 can be threadedly connected to the central ejection joint 253. An external thread can be formed on the outer wall of the central nozzle 254, and the central ejection joint 253 is threadedly connected to the external thread of the central nozzle 254.

[0085] Of course, in other embodiments, such as Figure 7 As shown, Figure 7 This is a schematic diagram of the structure of another central ejection assembly 25 provided in an embodiment of the present application. The central ejection assembly 25 may also include a central nozzle 254 and a nozzle fixing member 255. A central air outlet 252 is formed at one end of the central nozzle 254, and a central air inlet is formed on the nozzle fixing member 255. The nozzle fixing member 255 is connected to the central nozzle 254 and is disposed on the burner head 21 shown.

[0086] In this way, the nozzle fixing member 255 can fix the central nozzle 254 on the burner head 21. The central nozzle 254 can be directly connected to the gas pipeline, and the gas in the gas pipeline can be directly sprayed out through the central nozzle 254.

[0087] In some embodiments, Figure 5 As shown, the central ejection joint 253 includes a vertical portion 2531 and a horizontal portion 2532. The vertical portion 2531 extends in the same direction as the central fire channel 211 ( Figure 4 ) is parallel to the extension direction, one end of the vertical part 2531 faces the central fire channel 211 and is connected to the central nozzle 254.

[0088] In this way, since one end of the vertical portion 2531 faces the central fire channel 211 , the gas flowing out of the central nozzle 254 can flow toward the central fire channel 211 better and flow out from the other end of the central fire channel 211 .

[0089] The horizontal portion 2532 is connected to the other end of the vertical portion 2531, and the extension direction of the horizontal portion 2532 is parallel to the radial direction of the central fire channel 211. The horizontal portion 2532 is provided with a central air inlet 251 at one end away from the vertical portion 2531. Figure 4 As shown, the central fire channel 211 is located in the middle of the burner head 21 . Thus, due to the provision of the horizontal portion 2532 , the position of the central air inlet 251 can deviate from the middle of the bottom of the burner head 21 , thereby facilitating the connection of the gas pipeline with the central air inlet 251 .

[0090] In some embodiments, the burner 2 may further include a fastener (not shown). The horizontal portion 2532 and the burner head 21 are threadedly connected by the fastener. In this way, the horizontal portion 2532 and the burner head 21 can be connected more stably by the fastener. At the same time, when disassembling, it is only necessary to separate the fastener from the threaded connection between the horizontal portion 2532 and the burner head 21, and disassembly and installation are also more convenient.

[0091] For example, Figure 5 As shown, a first fixing portion 25321 is formed on the horizontal portion 2532, and a first fixing hole 25322 may be formed on the first fixing portion 25321. Figure 8 As shown, Figure 8 2 is a schematic structural diagram of a side of the burner head 21 close to the central ejection assembly 25 . A second fixing portion 216 is formed on the burner head 21 , and a second fixing hole 2161 is formed on the second fixing portion 216 .

[0092] In this way, the fastener can be inserted into the first fixing hole 25322, and extend into the second fixing hole 2161, and be threadedly connected with the second fixing portion 216. In this way, through the first fixing portion 25321 and the second fixing portion 216, the center ejector joint 253 and the furnace head 21 can be firmly connected.

[0093] For example, refer to Figure 5 The center ejection joint 253 can be integrally formed to directly produce the center ejection joint 253 with the first fixing portion 25321. In addition, for example, Figure 5 As shown, the first fixing portion 25321 may be located above the horizontal portion 2532 , and the first fixing portion 25321 may be a flat plate-like structure.

[0094] based on Figure 7 In some embodiments, the nozzle fixing member 255 may be provided with a third fixing hole 2551. Fig. 9 As shown, Fig. 9 This is a structural schematic diagram of another burner 2 provided in an embodiment of the present application, wherein a lead-out portion 219 is formed on one side of the burner head 21 away from the fire cover assembly 22, and a fourth fixing hole 2191 is formed on the lead-out portion 219. In this way, a fastener can be inserted into the third fixing hole 2551, and extend into the fourth fixing hole 2191, and be threadedly connected with the lead-out portion 219.

[0095] In some embodiments, the axis of the central fire channel 211 may coincide with the axis of the central gas outlet 252. In this way, the gas ejected from the central gas outlet 252 may flow to the other end of the central fire channel 211 better, so that the gas delivery effect is better and the gas delivery efficiency is improved.

[0096] Of course, in other embodiments, the axis of the center fire channel 211 may also have an angle with the axis of the center fire outlet. In this case, the gas ejected from the center fire outlet may also flow toward the other end of the center fire channel 211.

[0097] In order to facilitate the setting of the central ejection assembly 25, as Fig.10 As shown, Fig.10 The overall structure diagram of a burner 21 provided in an embodiment of the present application is shown in FIG. In some embodiments, the burner 21 may include a main body 217 and an extension 218. The main body 217 is provided with a central fire channel 211 ( Figure 4 ), and having a first gas mixing chamber 212 (with an opening) sequentially arranged around the periphery of the central fire channel 211 Figure 4 ) and the second gas mixing chamber 213 ( Figure 4 ). Fig.10 As shown, the main body 217 can be a substantially annular structure.

[0098] The extension portion 218 is located on a side of the main body 217 away from the fire cover assembly 22 and is connected to the main body 217. The extension portion 218 is partially arranged around the central fire channel 211. Fig.11 As shown, Fig.11 2 is a schematic diagram of the structure when the central ejection assembly 25 is installed on the burner head 21, and the central ejection assembly 25 is arranged side by side on one side of the extension portion 218. In this way, since the extension portion 218 is partially arranged around the central fire channel 211, the central ejection assembly 25 can be arranged on one side of the extension portion 218, and the placement of the central ejection assembly 25 is more convenient.

[0099] The extension portion 218 has a first connecting channel and a second connecting channel (not shown). The first connecting channel is connected to the first gas mixing chamber 212, and the second connecting channel is connected to the second gas mixing chamber 213. The first ejector tube 23 and the second ejector tube 24 are connected to the extension portion 218, respectively, and are connected to the first connecting channel and the second connecting channel, respectively. The extension portion 218 can be formed Figure 4 The first gas mixture inlet 214 and the second gas mixture inlet 215 are shown, and the first gas mixture inlet 214 and the second gas mixture inlet 215 are communicated with the first connecting channel and the second connecting channel respectively.

[0100] Thus, the mixed gas in the first ejector tube 23 can first enter the first connecting channel, then enter the first gas mixing chamber 212 from the first connecting channel, and finally flow out from the gas outlet fire hole 221 to be ignited. Similarly, the mixed gas in the second ejector tube 24 can first enter the second connecting channel, then enter the second gas mixing chamber 213 from the second connecting channel, and finally flow out from the gas outlet fire hole 221 to be ignited.

[0101] In addition, if Fig.10 As shown, the second fixing portion 216 may be located on one side of the main body 217 close to the extension portion 218 and connected to the main body 216. For example, the second fixing portion 216 may be integrally formed with the main body 217.

[0102] The shape of the second fixing portion 216 can be designed according to actual conditions. For example, the second fixing portion 216 can be block-shaped. In this case, the second fixing portion 216 has a simple structure and is easy to manufacture.

[0103] In order to allow the gas to enter the center nozzle 254 more smoothly from the center injection joint 253. In some embodiments, Fig.12 As shown, Fig.12 The cross-sectional view of the burner 2 provided in the embodiment of the present application shows that the first central air supply channel 2533 and the second central air supply channel 2534 are formed in the interior of the horizontal part 2532. The end of the first central air supply channel 2533 away from the second central air supply channel 2534 forms a central air inlet 251. The end of the second central air supply channel 2534 away from the first central air supply channel 2533 is in communication with the interior of the vertical part 2531.

[0104] The aperture of the first central gas supply channel 2533 is larger than the aperture of the second central gas supply channel 2534. In this way, the gas in the gas pipeline first enters the first central gas supply channel 2533. When the gas enters the second central gas supply channel 2534 from the first central gas supply channel 2533, the gas flow is more concentrated and the flow rate of the gas flow increases accordingly, so that the gas can be better delivered to the central nozzle 254 for ejection.

[0105] In addition, if Fig.13 As shown, Fig.13 In another cross-sectional view of the burner 2 provided in the embodiment of the present application, the horizontal portion 2532 may be roughly L-shaped. Accordingly, the second central air supply channel 2534 may also be L-shaped. Fig.13 As shown, a portion of the horizontal portion 2532 can be arranged in parallel with the extension portion 218, and another portion can extend toward the semi-enclosed structure formed by the extension portion 218, thereby facilitating the vertical portion 2531 ( Fig.12 ) and center fire channel 211( Figure 4 ) relative settings.

[0106] In some embodiments, Fig.14 As shown, Fig.14This is a structural schematic diagram of a fire cover assembly 22 provided in an embodiment of the present application. The fire cover assembly 22 may include an outer ring fire cover 222 , an inner ring fire cover 223 and a center fire cover 224 .

[0107] The outer ring fire cover 222 is disposed on the second gas mixing chamber 213 ( Figure 4 ) and is provided with an outer ring fire hole 2211 communicating with the second gas mixing chamber 213. The inner ring fire cover 223 is provided on the first gas mixing chamber 212 ( Figure 4 ) and is provided with an inner ring fire hole 2212 connected to the first gas mixing chamber 212. The center fire cover 224 is provided on the center fire channel 211 ( Figure 4 ) and is provided with a central fire hole 2213 connected to the central fire channel 211.

[0108] Thus, by providing the outer ring fire cover 222, the inner ring fire cover 223 and the central fire cover 224, the mixed gases in the first gas mixing chamber 212, the second gas mixing chamber 213 and the central fire channel 211 can flow out from one fire cover respectively, independently of each other. In this way, in actual application, when the user needs different fire powers, the user can control the central fire cover 224, the inner ring fire cover 223 and the outer ring fire cover 222 to select the required number of fire covers for ignition and combustion.

[0109] In some embodiments, Fig.15 As shown, Fig.15 Schematic diagram of the structure of a central fire cover 224 provided in an embodiment of the present application, wherein a limiting portion 2241 is formed at one end of the central fire cover 224 near the central fire channel 211. Fig.14 As shown, the central fire cover 224 overlaps the inner ring fire cover 223, and the stopper 2241 is located on the inner side of the inner ring fire cover 223. In this way, by providing the stopper 2241 at one end of the central fire cover 224 close to the central fire channel 211, the central fire cover 224 can be overlapped on the inner ring fire cover 223 more conveniently, and the assembly is more convenient. Fig.14 As shown, the central fire cover 224 is higher than the inner ring fire cover 223 by a certain height. In this way, during the cooking process, the distance between the central fire cover 224 and the pot is closer, which can further improve the combustion efficiency of the gas stove.

[0110] In some embodiments, Fig.16 As shown, Fig.16 The structural diagram of another fire cover assembly 22 provided in the embodiment of the present application is shown in FIG. 224. The central fire cover 224 can also be in the form of a sheet. The central fire cover 224 is located inside the inner ring fire cover 223 and is connected to the inner ring fire cover 223. At this time, the structure of the central fire cover 224 is relatively simple and easy to manufacture.

[0111] like Fig.17 As shown, Fig.17The structure diagram of the valve body 30, the adjusting member 40 and the control assembly 50 provided in the embodiment of the present application is shown in FIG. 1 . The gas stove provided in the embodiment of the present application may also include the valve body 30, the adjusting member 40 and the control assembly 50. The valve body 30 may be used to adjust the fire power of the burner 2.

[0112] like Fig.18 As shown, Fig.18 This is one of the cross-sectional views of the interior of the valve body 30 provided in the embodiment of the present application. A valve cavity 301 is formed inside the valve body 30, and has an air inlet channel 302, a first air outlet channel 303, a second air outlet channel 304, and a third air outlet channel 305, one end of which is connected to the valve cavity 301. The other end of the air inlet channel 302 can be connected to the gas pipeline. In this way, the gas in the gas pipeline can flow into the valve cavity 301 through the air inlet channel 302, and then flow into the first air outlet channel 303, the second air outlet channel 304, and the third air outlet channel 305 connected to the valve cavity 301.

[0113] It is understandable that the air inlet channel 302 and the valve chamber 301 may have different structures, as long as the air inlet channel 302 and the valve chamber 301 can be connected. Fig.19 and Fig. 20 As shown, Fig.19 This is a schematic diagram of the planar structure of the side where the air inlet channel 302 of the valve body 30 provided in the embodiment of the present application is connected to the gas channel. Fig. 20 for Fig.19 In the cross-sectional view at AA, the air inlet passage 302 includes a first air inlet section 3021 and a second air inlet section 3022. One end of the first air inlet section 3021 can be connected to the gas pipeline, and the other end is connected to the second air inlet section 3022. Fig.21 As shown, Fig.21 for Fig.19 In the cross-sectional view at BB, the second air intake section 3022 is also connected to the third air intake section 3023 , and the third air intake section 3023 is in communication with the valve chamber 301 .

[0114] In order to control the gas in the intake passage 302 to enter the valve chamber 301, as shown in FIG. Fig. 20 As shown, in some embodiments, the valve body 30 further has a control gas path 306 inside, and the control gas path 306 is connected to the first air inlet section 3021 and the second air inlet section 3022. At the same time, the gas stove also includes a switch valve 60. A part of the switch valve 60 extends into the control gas path 306. The switch valve 60 can control the connection or disconnection between the first air inlet section 3021 and the second air inlet section 3022.

[0115] The other end of the first gas outlet channel 303 is in communication with the first gas mixing chamber 212, and the other end of the second gas outlet channel 304 is in communication with the second gas mixing chamber 213. In this way, the gas can flow into the first gas mixing chamber 212 through the first gas outlet channel 303, flow into the second gas mixing chamber 213 through the second gas outlet channel 304, and then flow out through the gas outlet flame hole 221 on the fire cover assembly 22 for combustion.

[0116] like Fig.18 As shown, at least a portion of the regulating member 40 is located in the valve cavity 301, and is used to control the connection or disconnection between the first gas outlet channel 303, the second gas outlet channel 304, and the third gas outlet channel 305 and the valve cavity 301. In this way, by controlling the connection or disconnection between the first gas outlet channel 303, the second gas outlet channel 304, and the third gas outlet channel 305 and the valve cavity 301 through the regulating member 40, the effect of controlling the firepower can be achieved.

[0117] The control assembly 50 can be connected to the other end of the third gas outlet channel 305 and to the burner 2 ( Figure 2 ) is connected to control the connection or disconnection between the burner 2 and the third air outlet channel 305.

[0118] In this way, during the normal operation of the gas stove, the connection or disconnection between the third gas outlet channel 305 and the burner 2 can be controlled by the control component 50. Therefore, when stir-frying is required, the third gas outlet channel 305 and the burner 2 can be connected by the control component 50. On the basis of the ventilation of the first gas outlet channel 303 and the second gas outlet channel 304, the connection between the third gas outlet channel 305 and the burner 2 is newly added. This process does not reduce the air intake of the first gas outlet channel 303 and the second gas outlet channel 304. On the basis of ensuring the original firepower, the firepower of the gas stove is increased, and a real stir-frying function is realized.

[0119] It is understandable that for different types of burners 2, the third gas outlet channel 305 can be connected to the burner 2 in different ways to enhance the firepower of the gas stove. Exemplarily, when the burner head 21 of the burner 2 has only the first gas mixing chamber 212 and the second gas mixing chamber 213, the control component 50 can control the third gas outlet channel 305 to be connected to at least one of the first gas mixing chamber 212 or the second gas mixing chamber 213. In this way, by controlling the air intake of the third gas outlet channel 305 through the control component 50, the air intake amount in the first gas mixing chamber 212 or the second gas mixing chamber 213 increases, thereby enhancing the firepower of the first gas mixing chamber 212 and the second gas mixing chamber 213.

[0120] Or, for example, Figure 4As shown, when the burner head 21 has a central fire channel 211 in addition to the first gas mixing chamber 212 and the second gas mixing chamber 213, the control component 50 can control the third gas outlet channel 305 to communicate with the central fire channel 211. At this time, the firepower of the central fire channel 211 is added without reducing the firepower of the first gas mixing chamber 212 and the second gas mixing chamber 213, thereby improving the overall firepower of the burner 2.

[0121] In some embodiments, the gas stove further includes a detection element 70 and a controller. The detection element 70 is disposed on the valve body 30 and is used to determine the communication state between the first gas outlet channel 303, the second gas outlet channel 304 and the center fire channel 211 and the valve cavity 301 according to the state of the adjustment member 40.

[0122] The controller is electrically connected to the detection element 70 and the control assembly 50, and is used to control the control assembly 50 according to the signal of the detection element 70, so that the center fire channel 211 is connected or disconnected with the third gas outlet channel 305. In this way, when the gas stove is in normal operation, the detection element 70 can detect which state the adjustment member 40 is in. When the adjustment member 40 is in a state where the first gas outlet channel 303, the second gas outlet channel 304 and the center fire channel 211 are all connected with the valve chamber 301, the detection element 70 can feed back the above state to the controller. At this time, if the user starts the stir-fry state, the controller can control the control assembly 50 so that the burner 2 (for example, the center fire channel 211) is connected with the third gas outlet channel 305.

[0123] In some embodiments, Fig. 22 As shown, Fig. 22 This is a schematic diagram of the structure of a control assembly 50 provided in an embodiment of the present application. The control assembly 50 may include a solenoid valve seat 51 and a solenoid valve 52. A valve seat channel 511 is formed inside the solenoid valve seat 51, and has a valve seat air inlet 512 and a valve seat air outlet 513 connected to the valve seat channel 511. The valve seat air inlet 512 is connected to the third air outlet channel 305, and the valve seat air outlet 513 is connected to the burner 2 (for example, the center fire channel 211).

[0124] In this way, the gas in the third gas outlet channel 305 can enter the valve seat channel 511 through the valve seat air inlet 512, and then flow out to the burner 2 (for example, the center fire channel 211) through the valve seat air outlet 513, thereby finally increasing the firepower of the burner 2.

[0125] The solenoid valve 52 can be slidably connected to the solenoid valve seat 51, and at least partially located in the solenoid valve seat 51, and is used to control the flow or blocking of the valve seat channel 511. In this way, when the solenoid valve 52 controls the flow of the valve seat channel 511, the third gas outlet channel 305 can be connected to the central fire channel 211 to achieve the stir-frying function. When the stir-frying function is not needed, the solenoid valve 52 can be used to control the valve seat channel 511 to be blocked.

[0126] In some embodiments, Fig.23 As shown, Fig.23 The second cross-sectional view of the interior of the valve body 30 provided in the embodiment of the present application, the regulating member 40 may include a valve stem 41 and a valve core 42. A portion of the valve stem 41 is located outside the valve body 30, and another portion extends into the valve cavity 301. In actual application, the user can operate the valve stem 41.

[0127] The valve core 42 is located in the valve cavity 301, connected to one end of the valve stem 41 extending into the valve cavity 301, and is used to control the first air outlet channel 303, the second air outlet channel 304, and the third air outlet channel 305 to be connected or disconnected with the valve cavity 301 during the rotation driven by the valve stem 41. In this way, by manipulating the rotation of the valve stem 41, the valve core 42 can be driven to rotate, thereby controlling the first air outlet channel 303, the second air outlet channel 304, and the third air outlet channel 305 to be connected or disconnected with the valve cavity 301, which is simple and convenient to operate and easy to implement.

[0128] In some embodiments, the detection element 70 may be located outside the valve body 30, and located on the peripheral side of the valve stem 41. The detection element 70 includes an angle identifier, which may be used to detect the rotation angle of the valve stem 41. In this way, the angle of rotation of the valve stem 41 may be identified by the angle identifier, so that the overall operating state of the gas stove may be determined according to the rotation angle of the valve stem 41.

[0129] In some embodiments, Fig.24 As shown, Fig.24 for Fig.23 In the partial enlarged view at A in the middle, the valve core 42 is fitted with the inner wall of the valve cavity 301. A valve core channel 421 is formed inside the valve core 42, and the valve core 42 is provided with a valve core air inlet 422 connected to the valve core channel 421. The valve core air inlet 422 is connected to one end of the air inlet channel 302. In this way, the gas in the air inlet channel 302 can enter the interior of the valve core channel 421 through the valve core air inlet 422.

[0130] The circumferential wall of the valve core 42 is also provided with a first valve core outlet 423, a second valve core outlet 424 and a third valve core outlet 425 which are connected to the valve core channel 421. The first valve core outlet 423 is used to communicate with the first outlet channel 303, the second valve core outlet 424 is used to communicate with the second outlet channel 304, and the third valve core outlet 425 is used to communicate with the third outlet channel 305.

[0131] Therefore, during the rotation of the valve core 42, the first valve core outlet 423, the second valve core outlet 424 and the third valve core outlet 425 on the peripheral wall of the valve core 42 can be rotated, so that the first valve core outlet 423 and the first air outlet channel 303 are connected to each other, the second valve core outlet 424 and the second air outlet channel 304 are connected, and the third valve core outlet 425 and the third air outlet channel 305 are connected, so that firepower adjustment can be achieved according to different user needs.

[0132] In some embodiments, Fig.24 As shown, along the extension direction of the valve core 42, the first valve core outlet 423, the second valve core outlet 424 and the third valve core outlet 425 are arranged at different heights, and the first air outlet channel 303, the second air outlet channel 304 and the third air outlet channel 305 are at different heights along the extension direction of the valve core 42, and are at the same height as the first valve core outlet 423, the second valve core outlet 424 and the third valve core outlet 425, respectively.

[0133] In this way, since the first air outlet channel 303, the second air outlet channel 304 and the third air outlet channel 305 are at different heights, when designing the first air outlet channel 303, the second air outlet channel 304 and the third air outlet channel 305, they can be designed at different heights, and the air outlet channels will not interfere with each other, which makes the design of the first air outlet channel 303, the second air outlet channel 304 and the third air outlet channel 305 more convenient.

[0134] In some embodiments, Fig.24 As shown, along the extension direction of the valve core 42, the first valve core outlet 423, the second valve core outlet 424 and the third valve core outlet 425 are staggered. The first air outlet channel 303, the second air outlet channel 304 and the third air outlet channel 305 are staggered.

[0135] In this way, the first air outlet channel 303 , the second air outlet channel 304 and the third air outlet channel 305 can be arranged at different positions, and the first air outlet channel 303 , the second air outlet channel 304 and the third air outlet channel 305 are distributed more dispersedly, and the space inside the valve body 30 can be fully utilized.

[0136] It is understandable that, during the rotation of the valve core 42, the communication relationship between the first valve core outlet 423, the second valve core outlet 424 and the third valve core outlet 425 can be designed according to actual needs. Fig.25 As shown, Fig.25 This is a schematic diagram of the structure of a valve core 42 provided in an embodiment of the present application, wherein the first valve core outlet 423 and the second valve core outlet 424 are long strip outlets.

[0137] In this way, the first valve core outlet 423 can be communicated with the first gas outlet channel 303 as the valve core 42 rotates within a certain angle range, and the second valve core outlet 424 can be communicated with the second gas outlet channel 304 as the valve core 42 rotates within a certain angle range. In this way, within a certain angle range of the valve core 42 rotating, the first gas outlet channel 303 and the second gas outlet channel 304 can be communicated with the valve core channel 421 at the same time, realizing the function of high firepower.

[0138] In some embodiments, Fig.25 As shown, the third valve core outlet 425 is a circular hole-shaped outlet. At this time, when the valve core 42 is at a certain angle, the third valve core outlet 425 can be connected to the third gas outlet channel 305. It can be understood that when the third valve core outlet 425 is connected to the third gas outlet channel 305, the first gas outlet channel 303 can be completely opposite to the first valve core outlet 423, and the second gas outlet channel 304 can be completely opposite to the second valve core outlet 424. The gas in the valve core channel 421 fully enters the first gas outlet channel 303, the second gas outlet channel 304 and the third gas outlet channel 305 respectively.

[0139] At this time, the control component 50 can be used to control whether the third gas outlet channel 305 is connected to the burner 2, thereby realizing the stir-frying function of the gas stove.

[0140] In some embodiments, Fig.25 As shown, the shape of the valve core 42 can be a truncated cone. The end of the valve core 42 away from the valve stem 41 is the top surface of the truncated cone. In this way, when installing the valve core 42, the top surface of the valve core 42 first enters the interior of the valve body 30, and the installation is more convenient and smooth. Of course, the valve core 42 can also be other shapes, which can be specifically designed according to actual conditions. For example, in some embodiments, the valve core 42 can also be cylindrical.

[0141] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
