Description

Technical Field

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

[0002] Many smart cooktops in kitchens feature a one-touch stir-fry function. Current stir-fry designs typically connect a stir-fry channel before the mixing chamber, increasing the gas volume in a single mixing chamber to achieve the function, without altering the structure of the mixing chamber and burner cap. Furthermore, most existing stir-fry technologies rely on complex multi-channel structures. For example, they may use a separate stir-fry combustion channel or a valve with three gas outlets to control the stir-fry pipes. These complex designs not only increase manufacturing costs but may also lead to difficulties in maintenance and cleaning. In addition, multi-channel designs can cause uneven combustion efficiency and imprecise heat control, affecting cooking results and user experience. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the complex stir-fry structure design of the prior art and to provide a gas stove.

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

[0005] A gas stove includes a mixing chamber, a stir-fry valve, and a stopcock valve. The mixing chamber includes an inner ring mixing chamber, a middle ring mixing chamber, and an outer ring mixing chamber. The middle ring mixing chamber is fitted around the outer periphery of the inner ring mixing chamber, and the outer ring mixing chamber is fitted around the outer periphery of the middle ring mixing chamber. A burner cap is provided above the mixing chamber. The burner cap has inner ring burner holes, middle ring burner holes, and outer ring burner holes. The inner ring burner holes are connected to the inner ring mixing chamber, the middle ring burner holes are connected to the middle ring mixing chamber, and the outer ring burner holes are connected to the outer ring mixing chamber.

[0006] The stir-fry valve includes a gas inlet channel, a first gas channel, and a second gas channel. The gas inlet channel is connected to the stopcock valve, the first gas channel is connected to the middle ring mixing chamber, and the second gas channel is connected to the inner ring mixing chamber.

[0007] The stir-fry valve includes a valve cavity and a stir-fry valve core. The gas inlet channel, the first gas channel and the second gas channel are respectively connected to the valve cavity. The stir-fry valve core is disposed inside the valve cavity and moves relative to the valve cavity to switch the stir-fry valve between a stir-fry state and a normal state.

[0008] In the normal state, the gas intake passage is connected to the first gas passage, but not connected to the second gas passage;

[0009] During the stir-frying process, the gas intake channel is simultaneously connected to both the first gas channel and the second gas channel.

[0010] In this design, the first gas passage is always connected to the gas intake passage to ensure that, when the gas stove is in normal operation, the high-heat valve can stably supply the gas required for normal cooking to the mixing chamber, thus ensuring the stability of the gas stove's operation during normal cooking. When the gas stove is in high-heat mode, both the first and second gas passages are connected to the gas intake passage, allowing both the inner and middle ring mixing chambers to receive gas simultaneously. Although the gas input through the gas intake passage remains unchanged, the gas is intercepted by the nozzle before entering the corresponding mixing chamber, resulting in a gas input through the gas intake passage exceeding the actual gas supply to the mixing chamber. Therefore, when the gas stove is in high-heat mode, the total gas volume in the inner and middle ring mixing chambers is greater than the gas volume in a single middle ring mixing chamber when the gas stove is in normal operation. This results in increased heat output when the gas stove is in high-heat mode, achieving the high-heat function. The high-heat cooking valve can directly use the ordinary gas pipeline of the stopcock valve for gas supply, eliminating the need for a separate high-heat cooking pipeline and modifications to the valve body structure. This simplifies the internal structure of the gas stove and reduces its footprint. Furthermore, since the gas for high-heat cooking flows into the inner ring mixing chamber, the flow-cutting range of the nozzle corresponding to the middle ring mixing chamber does not need to be changed. This ensures that the nozzle in the middle ring mixing chamber can properly cut off the gas flow into the middle ring mixing chamber when the gas stove is in normal operation, guaranteeing the reliability of normal cooking modes.

[0011] Preferably, the first gas passage and the second gas passage are spaced apart along the moving direction of the stir-fry valve core, and the gas intake passage is located on the side of the second gas passage facing the first gas passage in the moving direction of the stir-fry valve core;

[0012] In the normal state, the stir-fry valve core is located on the side of the first gas passage and the gas intake passage facing the second gas passage in the direction of movement of the stir-fry valve core;

[0013] In the stir-frying state, the stir-frying valve core is located on the side of the first gas passage and the gas intake passage away from the second gas passage in the direction of movement of the stir-frying valve core.

[0014] In this design, the two gas passages are spaced apart, making them independent of each other. During the movement of the stir-fry valve core, it only acts on the second gas passage to control its opening and closing, without affecting the normal flow of gas in the first passage. The gas intake passage is located on the side of the second gas passage facing the first gas passage, ensuring that the gas intake passage is connected only to the first gas passage.

[0015] Preferably, the gas intake channel and the first gas channel have their axes coincident and are respectively located on opposite sides of the valve cavity, and the moving direction of the stir-fry valve core forms an angle with the axial direction of the gas intake channel.

[0016] In this design, the aforementioned configuration ensures unobstructed flow of gas from the gas intake channel to the first gas channel, reducing turns and other obstructions during gas flow, avoiding unnecessary resistance, and minimizing the gas flow path for a more stable airflow. Simultaneously, the axis of the gas intake channel forms an angle with the direction of movement of the stir-fry valve core. The movement of the stir-fry valve core does not affect the normal flow between the gas intake channel and the first gas channel; the stir-fry valve core cannot seal either the gas intake channel or the first gas channel, ensuring continuous gas flow under normal conditions.

[0017] Preferably, the moving direction of the stir-fry valve core is perpendicular to the axial direction of the gas intake channel.

[0018] Preferably, the first gas passage and the second gas passage are located on the same side of the valve chamber.

[0019] In this design, the structure of the stir-fry valve is made more compact by arranging the first and second gas passages on the same side at intervals. During stir-frying, gas flows into both the first and second gas passages simultaneously, with the gas flow direction being the same. Furthermore, the outlets of the first and second gas passages are close to each other, facilitating the overall pipeline layout of the gas stove.

[0020] Preferably, the axis of the first gas passage is parallel to the axis of the second gas passage.

[0021] In this solution, the layout of the first and second gas channels makes the structure of the entire stir-fry valve more reasonable. The parallel arrangement effectively shortens the flow path of the gas in the second gas channel during stir-frying, allowing users to quickly start stir-frying after switching, thus improving the user experience.

[0022] Preferably, the stir-fry valve further includes a connecting channel, the two ends of which are respectively connected to the second gas channel and the valve chamber, and the extending direction of the connecting channel is parallel to the moving direction of the stir-fry valve core;

[0023] When the stir-fry valve is in the normal state, the stir-fry valve core closes the port at the end of the connection channel that communicates with the valve cavity.

[0024] In this solution, the first gas passage and the valve chamber are connected by setting a connecting channel, which shortens the movement path of the stir-fry valve core. This allows the stir-fry valve core to move into place more quickly during the switching process, improving the switching efficiency. Moreover, the movement direction of the stir-fry valve core is the same as the extension direction of the connecting channel, and the stir-fry valve core can directly seal the port of the connecting channel, making the cooperation between the stir-fry valve core and the connecting channel more convenient.

[0025] Preferably, the stir-fry valve further includes a protrusion, one end of which is connected to the end face of the connecting channel facing the stir-fry valve core, and the other end of which extends into the interior of the valve cavity along the moving direction of the stir-fry valve core.

[0026] In this solution, the above-mentioned settings can further shorten the movement path of the stir-fry valve core, enabling the stir-fry valve core to quickly abut against the end face of the protrusion, thereby improving the switching efficiency between the stir-fry state and the normal state.

[0027] Preferably, the gas stove further includes an inner ring burner cap, which covers the inner ring mixing chamber and the middle ring mixing chamber, and the inner ring burner cap is provided with the inner ring burner hole and the middle ring burner hole.

[0028] In this design, an inner ring burner covers both the inner and middle ring mixing chambers. The switching between normal and high-heat states is achieved solely through two different types of flame holes on the inner ring burner. When the high-heat valve is in the normal state, the middle ring mixing chamber is connected to the middle ring flame hole. When the high-heat valve is in the high-heat state, both the middle and inner ring mixing chambers are connected, and flames are emitted from both the middle and inner ring flame holes, resulting in changes in flame intensity and flame pattern.

[0029] Preferably, the inner ring flame hole is located on the upper side wall of the inner ring flame cover, the middle ring flame hole is located on the peripheral side wall of the inner ring flame cover, the axis of the inner ring flame hole is parallel to the vertical direction, and the middle ring flame hole is inclined upward from the radial inner side of the inner ring flame cover to the radial outer side of the inner ring flame cover.

[0030] In this design, the middle ring of flame holes is arranged at an angle on the outside of the burner cap, producing a large overall flame ring, but the flames are not dense, making it suitable for ordinary cooking. The inner ring of flame holes is concentrated and extends vertically, resulting in a concentrated flame. When stir-frying, both the inner and middle ring of flame holes produce flames simultaneously, increasing the overall heat coverage area, making it suitable for stir-frying.

[0031] The positive and progressive effects of this utility model are as follows: The first gas passage is always connected to the gas intake passage to ensure that when the gas stove is in normal operation, the stir-fry valve can stably supply the gas required for normal cooking to the mixing chamber, thus ensuring the stability of the gas stove in normal cooking mode. When the gas stove is in stir-fry mode, the first and second gas passages are simultaneously connected to the gas intake passage, thereby allowing the inner ring mixing chamber and the middle ring mixing chamber to receive gas simultaneously. Although the gas input volume of the gas intake passage does not change, because the gas is intercepted by the nozzle before entering the corresponding mixing chamber, the gas input volume of the gas intake passage is greater than the actual gas supply to the mixing chamber. Therefore, when the gas stove is in stir-fry mode, the total gas volume in the inner ring mixing chamber and the middle ring mixing chamber is greater than the gas volume in a single middle ring mixing chamber when the gas stove is in normal operation, thereby increasing the heat obtained by the gas stove in stir-fry mode and realizing the stir-fry function. The high-heat cooking valve can directly use the ordinary gas pipeline of the stopcock valve for gas supply, eliminating the need for a separate high-heat cooking pipeline and modifications to the valve body structure. This simplifies the internal structure of the gas stove and reduces its footprint. Furthermore, since the gas for high-heat cooking flows into the inner ring mixing chamber, the flow-cutting range of the nozzle corresponding to the middle ring mixing chamber does not need to be changed. This ensures that the nozzle in the middle ring mixing chamber can properly cut off the gas flow into the middle ring mixing chamber when the gas stove is in normal operation, guaranteeing the reliability of normal cooking modes.

[0059] The present invention will be described more clearly and completely below with reference to the accompanying drawings, using a preferred embodiment as an example.

[0060] This embodiment provides a gas stove, such as Figure 1-5 As shown, the gas stove includes a mixing chamber 100, a stir-fry valve 200, and a stopcock valve 300. The mixing chamber 100 includes an inner ring mixing chamber 110, a middle ring mixing chamber 120, and an outer ring mixing chamber 130. The middle ring mixing chamber 120 is fitted around the outer periphery of the inner ring mixing chamber 110, and the outer ring mixing chamber 130 is fitted around the outer periphery of the middle ring mixing chamber 120. A burner cap 400 is provided above the mixing chamber 100. The burner cap 400 is provided with an inner ring burner hole 411, a middle ring burner hole 412, and an outer ring burner hole 421. The inner ring burner hole 411 is connected to the inner ring mixing chamber 110, the middle ring burner hole 412 is connected to the middle ring mixing chamber 120, and the outer ring burner hole 421 is connected to the outer ring mixing chamber 130.

[0061] Specifically, such as Figure 4As shown, the stopcock valve 300 includes a first outlet channel 310 and a second outlet channel 320, and the stir-fry valve 200 includes a gas intake channel 210, a first gas channel 220, and a second gas channel 230. The gas intake channel 210 is connected to the first outlet channel 310 of the stopcock valve 300, the middle ring mixing chamber 120 is connected to the first gas channel 220, the inner ring mixing chamber 110 is connected to the second gas channel 230, and the outer ring mixing chamber 130 is connected to the second outlet channel 320 of the stopcock valve 300.

[0062] The stir-fry valve 200 also includes a valve cavity 240 and a stir-fry valve core 250. The gas intake channel 210, the first gas channel 220 and the second gas channel 230 are respectively connected to the valve cavity 240. The stir-fry valve core 250 is disposed inside the valve cavity 240 and moves relative to the valve cavity 240 to switch the stir-fry valve 200 between the stir-fry state and the normal state.

[0063] In normal conditions, the gas intake passage 210 is connected to the first gas passage 220, but not to the second gas passage 230. That is, in normal conditions, the middle ring mixing chamber 120 is always connected to the stop valve 300 through the first gas passage 220, while the inner ring mixing chamber 110 is not connected to the stop valve 300.

[0064] During stir-frying, the gas intake passage 210 is simultaneously connected to the first gas passage 220 and the second gas passage 230. That is, the inner ring mixing chamber 110 and the middle ring mixing chamber 120 are simultaneously connected to the stopcock valve 300.

[0065] The first gas passage 220 is always connected to the gas intake passage 210 to ensure that, when the gas stove is in normal operation, the stir-fry valve 200 can stably supply the gas required for normal cooking to the mixing chamber 100, thus ensuring the stability of the gas stove in normal cooking mode. When the gas stove is in stir-fry mode, the first gas passage 220 and the second gas passage 230 are simultaneously connected to the gas intake passage 210, thereby allowing the inner ring mixing chamber 110 and the middle ring mixing chamber 120 to simultaneously receive gas. Although the gas input of the gas intake passage 210 does not change, because the gas is intercepted by the nozzle before entering the corresponding mixing chamber 100, the gas input of the gas intake passage 210 is greater than the actual gas supplied to the mixing chamber 100. Therefore, when the gas stove is in stir-fry mode, the total gas volume in the inner ring mixing chamber 110 and the middle ring mixing chamber 120 is greater than the gas volume in a single middle ring mixing chamber 120 when the gas stove is in normal operation, thus increasing the heat obtained by the gas stove in stir-fry mode and realizing the stir-fry function. The high-heat valve 200 can directly use the ordinary gas pipeline of the stopcock valve 300 for gas supply, without the need for a separate dedicated high-heat pipeline or any modification to the valve body structure of the stopcock valve 300. This simplifies the internal structure of the gas stove and reduces its footprint. Furthermore, since the gas for high-heat cooking flows into the inner ring mixing chamber 110, the flow-cutting range of the nozzle corresponding to the middle ring mixing chamber 120 does not need to be changed. This ensures that the nozzle corresponding to the middle ring mixing chamber 120 can properly cut off the gas flowing into the middle ring mixing chamber 120 when the gas stove is in normal operation, guaranteeing the reliability of normal cooking modes.

[0066] Among them, such as Figure 2-3 As shown, the first gas passage 220 and the second gas passage 230 are spaced apart along the moving direction of the stir-fry valve core 250. The gas intake passage 210 is located on the side of the second gas passage 230 facing the first gas passage 220 in the moving direction of the stir-fry valve core 250. In the normal state, the stir-fry valve core 250 is located on the side of the first gas passage 220 and the gas intake passage 210 facing the second gas passage 230 in the moving direction of the stir-fry valve core 250. In the stir-fry state, the stir-fry valve core 250 is located on the side of the first gas passage 220 and the gas intake passage 210 away from the second gas passage 230 in the moving direction of the stir-fry valve core 250.

[0067] The two gas passages are spaced apart, making the first gas passage 220 and the second gas passage 230 independent of each other. During the movement of the stir-fry valve core 250, it only acts on the second gas passage 230 to control its opening and closing, without affecting the normal flow of the first gas passage 220. The gas intake passage 210 is located on the side of the second gas passage 230 facing the first gas passage 220, so that the gas intake passage 210 can only communicate with the first gas passage 220.

[0068] Furthermore, the axes of the gas intake passage 210 and the first gas passage 220 coincide and are respectively located on opposite sides of the valve chamber 240. The moving direction of the stir-fry valve core 250 forms an angle with the axial direction of the gas intake passage 210. This arrangement ensures unobstructed gas flow from the gas intake passage 210 to the first gas passage 220, reducing turns and other deviations in gas flow, avoiding unnecessary resistance, and shortening the gas flow path for more stable airflow. Simultaneously, the angle between the axis of the gas intake passage 210 and the moving direction of the stir-fry valve core 250 ensures that the normal flow between the gas intake passage 210 and the first gas passage 220 is not affected during the movement of the stir-fry valve core 250. The stir-fry valve core 250 cannot seal the gas intake passage 210 and the first gas passage 220, and gas continues to flow under normal conditions.

[0069] Specifically, the moving direction of the stir-fry valve core 250 is perpendicular to the axis of the gas intake passage 210. In other embodiments, the relative positions of the first gas passage 220, the second gas passage 230, and the gas intake passage 210 are not specifically limited. The first gas passage 220 and the gas intake passage 210 can be staggered in the moving direction of the stir-fry valve core 250, as long as the movement of the stir-fry valve core 250 can cooperate with the second gas passage 230 without affecting the normal connection between the first gas passage 220 and the gas intake passage 210.

[0070] In this embodiment, as Figure 2-3 As shown, the first gas passage 220 and the second gas passage 230 are located on the same side of the valve chamber 240. By arranging the first gas passage 220 and the second gas passage 230 on the same side at intervals, the overall structure of the stir-fry valve 200 is made more compact. In the stir-frying state, gas flows into the first gas passage 220 and the second gas passage 230 simultaneously, with the gas flow direction being the same. Furthermore, the outlets of the first gas passage 220 and the second gas passage 230 are close to each other, facilitating the overall pipeline layout of the gas stove.

[0071] Furthermore, the axes of the first gas passage 220 and the second gas passage 230 are parallel to each other, making the overall structure of the stir-fry valve 200 more reasonable. This parallel arrangement effectively shortens the gas flow path in the second gas passage 230 during stir-frying, allowing users to quickly start stir-frying after switching modes, thus improving the user experience. In other alternative embodiments, the gas intake passage 210, the first gas passage 220, and the second gas passage 230 can be located on the same side of the valve cavity 240. Alternatively, one of the first gas passage 220 and the second gas passage 230 can be located on one side of the valve cavity 240 along with the gas intake passage 210, while the other of the first gas passage 220 and the second gas passage 230 can be located on the other side of the valve cavity 240.

[0072] In this embodiment, as Figure 3 As shown, the stir-fry valve 200 also includes a connecting channel 231, the two ends of which are connected to the second gas channel 230 and the valve chamber 240, respectively. The extension direction of the connecting channel 231 is parallel to the movement direction of the stir-fry valve core 250. When the stir-fry valve 200 is in the normal state, the stir-fry valve core 250 closes the port at the end of the connecting channel 231 that is connected to the valve chamber 240.

[0073] In this embodiment, the first gas passage 220 and the valve chamber 240 are connected by a connecting channel 231, shortening the movement path of the stir-fry valve core 250. This allows the stir-fry valve core 250 to move into position more quickly during switching, improving switching efficiency. Furthermore, the movement direction of the stir-fry valve core 250 is the same as the extension direction of the connecting channel 231, allowing the stir-fry valve core 250 to directly seal the port of the connecting channel 231, making the cooperation between the stir-fry valve core 250 and the connecting channel 231 more convenient. In other embodiments, the connecting channel 231 may not be provided; instead, an opening may be provided on the side of the first gas passage 220 near the valve chamber 240, achieving sealing solely through the opening between the stir-fry valve core 250 and the first gas passage 220.

[0074] Furthermore, the stir-fry valve 200 also includes a protrusion 232. One end of the protrusion 232 is connected to the end face of the connecting channel 231 facing the stir-fry valve core 250, and the other end of the protrusion 232 extends into the interior of the valve cavity 240 along the moving direction of the stir-fry valve core 250. This configuration further shortens the moving path of the stir-fry valve core 250, allowing the stir-fry valve core 250 to quickly abut against the end face of the protrusion 232, thus improving the switching efficiency between the stir-fry state and the normal state.

[0075] In this embodiment, as Figure 4-5 As shown, the gas stove also includes an inner ring burner cap 410, which covers the inner ring mixing chamber 110 and the middle ring mixing chamber 120. The inner ring burner cap 410 is provided with an inner ring flame hole 411 and a middle ring flame hole 412. In this embodiment, the inner ring burner cap 410 covers the two mixing chambers 100, the inner ring mixing chamber 110 and the middle ring mixing chamber 120, and the switching between the normal state and the high-heat state is achieved only through the two different flame holes on the inner ring burner cap 410. When the high-heat valve 200 is in the normal state, the middle ring mixing chamber 120 is connected to the middle ring flame hole 412. When the high-heat valve 200 is in the high-heat state, the middle ring mixing chamber 120 and the inner ring mixing chamber 110 are connected at the same time, and both the middle ring flame hole 412 and the inner ring flame hole 411 emit flames, resulting in changes in firepower and flame shape. In other embodiments, different flame covers 400 can be set to cover the inner ring mixing chamber 110 and the middle ring mixing chamber 120 respectively, as long as different flame patterns can be generated when switching between normal state and stir-fry state.

[0076] Specifically, the inner ring flame holes 411 are located on the upper side wall of the inner ring flame cap 410, and the middle ring flame holes 412 are located on the peripheral side wall of the inner ring flame cap 410. The axis of the inner ring flame holes 411 is parallel to the vertical direction, and the middle ring flame holes 412 are inclined upwards from the radially inner side to the radially outer side of the inner ring flame cap 410. The middle ring flame holes 412 are inclined on the outer side of the flame cap 400, resulting in a larger overall flame ring, but the flames are not dense, making it suitable for ordinary cooking. The inner ring flame holes 411 are concentrated and extend vertically, resulting in concentrated flames. During stir-frying, the inner ring flame holes 411 and the middle ring flame holes 412 produce flames simultaneously, increasing the overall heat coverage area, making it suitable for stir-frying.

[0077] In other embodiments, the structure of the burner cap 400 and the burner holes is not specifically limited. For example, the inner ring burner hole 411 can also be set on the peripheral side of the inner ring burner cap 410 to form a double-layer burner hole structure with the middle ring burner hole 412, so that stir-frying can be achieved only by changing the heat.

[0078] While specific embodiments of this utility model have been described above, those skilled in the art should understand that these are merely illustrative examples, and the scope of protection of this utility model is defined by the appended claims. Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this utility model, but all such changes and modifications fall within the scope of protection of this utility model.
