[0002] Existing gas stoves are equipped with regular mode and stir-fry mode to meet diverse cooking environments. The heat of the stir-fry mode is much greater than that of the regular mode. Currently, most stir-fry modes require modification of the gas valve, which makes the structure of the gas valve more complex and can only create a stir-fry effect on the outer or inner ring of the burner, resulting in uneven temperature of the cookware.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features.

[0046] The first aspect of this application discloses a gas control device, combined with Figures 1 to 14 As shown, in some embodiments, the gas control device includes an inlet seat 1000, a control valve 2000, and a first gas valve 3000. The inlet seat 1000 is provided with an inlet channel 1100, a first outlet channel 1200, and an auxiliary channel 1400. The first outlet channel 1200 is connected to the inlet channel 1100, and the auxiliary channel 1400 is connected to the first outlet channel 1200 so that gas can flow from the auxiliary channel 1400 to the first outlet channel 1200. The auxiliary channel 1400 is provided with an inlet port 1410. The control valve 2000 is connected to the inlet seat 1000. 000 includes a valve core 2200, which is movably configured to abut and disengage from the air inlet 1410. When the valve core 2200 abuts the air inlet 1410, the valve core 2200 closes the air inlet 1410. When the valve core 2200 disengages from the air inlet 1410, the valve core 2200 opens the air inlet 1410, thereby connecting the air inlet 1410 with the air intake passage 1100. The first gas valve 3000 is connected to the air intake seat 1000 and is connected to the first outlet 1221 of the first gas outlet passage 1200.

[0047] By setting a first exhaust channel 1200 and an auxiliary channel 1400 in the air intake seat 1000, the first gas valve 3000 can be supplied with normal gas through the first exhaust channel 1200 when the auxiliary channel 1400 is closed, and the first gas valve 3000 can be supplied with gas for stir-frying through the auxiliary channel 1400 and the first exhaust channel 1200 when the auxiliary channel 1400 is open. There is no need to modify the structure of the first gas valve 3000. The first gas valve 3000 can adopt mature products currently on the market, with strong compatibility, which helps to reduce structural complexity and cost.

[0048] Specifically, the air inlet 1000 needs to be connected to a gas source, which can be bottled liquefied petroleum gas (LPG) or piped natural gas. The gas source is connected to the air inlet channel 1100 of the air inlet 1000. The gas supplied by the gas source enters the interior of the air inlet 1000 through the air inlet channel 1100 and can then be discharged through the first air outlet channel 1200. The air inlet 1000 can be a one-piece molded structure or a combination of separate components. Since the air inlet 1000 has multiple channels (air inlet channel 1100, first air outlet channel 1200, and auxiliary channel 1400), designing the air inlet 1000 as a one-piece molded structure is more conducive to preventing gas leakage and reducing the number of sealing points.

[0049] The first gas valve 3000 is connected to the air inlet seat 1000 and communicates with the first outlet 1221 of the first gas outlet channel 1200. Gas entering the air inlet seat 1000 through the air inlet channel 1100 can be discharged through the first gas outlet channel 1200 and flow through the first gas valve 3000. The first gas valve 3000 can regulate the flow rate of the gas. The first gas valve 3000 can be of various types, such as a plug valve, ball valve, or butterfly valve, and can be selected according to the actual situation. A plug valve is commonly used in gas stoves. The first gas valve 3000 and the air inlet seat 1000 are separate components connected and fixed by means such as screws or welding.

[0050] In this embodiment, the air intake seat 1000 is provided with an auxiliary channel 1400. The auxiliary channel 1400 needs to cooperate with the control valve 2000 to switch between normal gas supply and stir-fry gas supply to the first gas valve 3000. The auxiliary channel 1400 is connected to the first gas outlet channel 1200 so that gas can flow from the auxiliary channel 1400 to the first gas outlet channel 1200. The auxiliary channel 1400 is provided with an air inlet 1410. The control valve 2000 includes a valve core 2200, which is a movable part. The movement of the valve core 2200 has two states: the first state is that the valve core 2200 abuts against the air inlet 1410, and the second state is that the valve core 2200 disengages from the air inlet 1410. When the valve core 2200 abuts against the air inlet 1410, the valve core 2200 closes the air inlet 1410 (i.e., closes the auxiliary channel 1400). When the valve core 2200 disengages from the air inlet 1410, the valve core 2200 opens the air inlet 1410 (i.e., opens the auxiliary channel 1400). Since the first outlet channel 1200 is connected to the air inlet channel 1100, the gas can be discharged through the first outlet channel 1200 regardless of whether the valve core 2200 abuts against or disengages from the air inlet 1410. However, when the valve core 2200 disengages from the air inlet 1410, the gas can still flow into the first outlet channel 1200 through the auxiliary channel 1400. The gas passage 1200 increases the gas flow rate / pressure entering the first gas outlet passage 1200. When the valve core 2200 abuts against the air inlet 1410, the gas cannot flow into the first gas outlet passage 1200 through the auxiliary passage 1400, thus reducing the gas flow rate / pressure entering the first gas outlet passage 1200. In other words, when the valve core 2200 abuts against the air inlet 1410, it can achieve normal gas supply to the first gas valve 3000, and when the valve core 2200 disengages from the air inlet 1410, it can achieve high-heat gas supply to the first gas valve 3000 (the heat of high-heat gas supply is greater than that of normal gas supply).

[0051] Taking a gas stove as an example, the gas control device will be further explained. The gas stove includes a gas control device and a first burner. The air inlet channel 1100 of the air inlet seat 1000 is connected to the gas source, and the first gas valve 3000 controls the gas flow to the first burner. The gas flow pattern is as follows:

[0052] In the first configuration, the valve core 2200 abuts against the air inlet 1410, opening the first gas valve 3000. Gas enters the interior of the air inlet seat 1000 from the air inlet channel 1100 and flows into the first air outlet channel 1200 from the interior of the air inlet seat 1000. The gas flows along the first air outlet channel 1200 and through the first gas valve 3000, thus achieving normal gas supply to the first gas valve 3000. The first gas valve 3000 can regulate the gas flow to the first burner. At this time, the gas stove can achieve normal heating through the first burner.

[0053] In the second scenario, the valve core 2200 disengages from the air inlet 1410, opening the first gas valve 3000. Gas enters the interior of the air inlet seat 1000 through the air inlet channel 1100 and flows into the first air outlet channel 1200 from inside the air inlet seat 1000. It then flows from inside the air inlet seat 1000 through the air inlet 1410 into the auxiliary channel 1400 and then into the first air outlet channel 1200 (i.e., compared to the case where the valve core 2200 is in contact with the air inlet 1410, an additional path is added for gas to flow into the first air outlet channel 1200 through the auxiliary channel 1400). This achieves gas supply for stir-frying using the first gas valve 3000. The first gas valve 3000 can regulate the gas flow to the first burner, allowing the gas stove to achieve stir-frying mode heating through the first burner.

[0054] Generally, the first burner is equipped with inner and outer ring flame holes, and the first gas valve 3000 has an inner ring channel 3100 and an outer ring channel 3200. The inner ring channel 3100 controls the gas supply to the inner ring flame holes, and the outer ring channel 3200 controls the gas supply to the outer ring flame holes. Whether the valve core 2200 is in contact with the air inlet 1410 to provide normal gas supply to the first gas valve 3000 or disconnected from the air inlet 1410 to provide high-heat gas supply to the first gas valve 3000, it is a function of the entire first gas valve 3000. The gas supply is adjusted so that when the first gas valve 3000 is supplied with gas normally, the outer ring channel 3200 and the inner ring channel 3100 of the first gas valve 3000 can be supplied with gas normally, and when the first gas valve 3000 is supplied with gas for stir-frying, the outer ring channel 3200 and the inner ring channel 3100 of the first gas valve 3000 can be supplied with gas for stir-frying at the same time, and the cookware can be heated more evenly.

[0055] Combination Figures 6 to 14 As shown, in some embodiments, the air intake seat 1000 is provided with a receiving cavity 1500, the valve core 2200 is movably disposed in the receiving cavity 1500, the air intake channel 1100 is connected to the receiving cavity 1500, the first air outlet channel 1200 is connected to the receiving cavity 1500, and when the valve core 2200 is disengaged from the air inlet 1410, the air inlet 1410 is connected to the receiving cavity 1500.

[0056] It is understandable that the connection between the intake passage 1100 and the accommodating cavity 1500 means that the gas flows from the intake passage 1100 into the accommodating cavity 1500 (the gas flowing along the intake passage 1100 flows into the accommodating cavity 1500), the connection between the first exhaust passage 1200 and the accommodating cavity 1500 means that the gas flows from the accommodating cavity 1500 into the first exhaust passage 1200 (the gas flowing into the accommodating cavity 1500 continues to flow into the first exhaust passage 1200), and the connection between the intake port 1410 and the accommodating cavity 1500 means that the gas flows from the accommodating cavity 1500 into the auxiliary passage 1400 (the gas flowing into the accommodating cavity 1500 continues to flow into the auxiliary passage 1400).

[0057] The arrangement of the accommodating cavity 1500 facilitates the movement of the valve core 2200 and also establishes the connection between the channels (intake channel 1100 and the first outlet channel 1200, and intake channel 1100 and auxiliary channel 1400). For example, the accommodating cavity 1500 has an opening 1510. The control valve 2000 is aligned with the opening 1510 and installed on the intake seat 1000. The valve core 2200 passes through the opening 1510 and is inserted into the accommodating cavity 1500, allowing the valve core 2200 to move within the accommodating cavity 1500. The control valve 2000 is connected and fixed to the intake seat 1000, thus covering the opening 1510 and sealing the accommodating cavity 1500.

[0058] Assuming a 1500mm accommodating cavity, the gas flow pattern is as follows:

[0059] In the first configuration, the valve core 2200 abuts against the air inlet 1410, opening the first gas valve 3000. Gas enters the accommodating cavity 1500 from the air inlet channel 1100 and flows from the accommodating cavity 1500 into the first air outlet channel 1200. The gas flows along the first air outlet channel 1200 and through the first gas valve 3000, thus achieving normal gas supply to the first gas valve 3000. The first gas valve 3000 can regulate the gas flow to the first burner. At this time, the gas stove can achieve normal heating through the first burner.

[0060] In the second scenario, the valve core 2200 disengages from the air inlet 1410, opening the first gas valve 3000. Gas enters the accommodating cavity 1500 from the air inlet channel 1100 and flows from the accommodating cavity 1500 into the first gas outlet channel 1200. Gas then flows from the accommodating cavity 1500 through the air inlet 1410 into the auxiliary channel 1400 and then from the auxiliary channel 1400 into the first gas outlet channel 1200 (i.e., compared to the case where the valve core 2200 is in contact with the air inlet 1410, an additional path is added for gas to flow from the auxiliary channel 1400 into the first gas outlet channel 1200). This achieves gas supply for stir-frying using the first gas valve 3000. The first gas valve 3000 can regulate the gas flow to the first burner, allowing the gas stove to achieve stir-frying mode heating through the first burner.

[0061] Combination Figures 7 to 10 As shown, in some embodiments, the air intake channel 1100 includes a first air intake channel 1110 and a second air intake channel 1120, which are intersecting and connected (intersecting means that the two intersecting channels are not on the same straight line, the same below). The first air intake channel 1110 forms an inlet 1111 of the air intake channel 1100, and the second air intake channel 1120 is connected to the accommodating cavity 1500. The first intake passage 1110 is located upstream of the second intake passage 1120. It can receive gas through the first intake passage 1110. For example, the first intake passage 1110 forms the inlet 1111 of the intake passage 1100. The gas source can be connected to the inlet 1111 of the intake passage 1100. After the gas enters the intake passage 1100, it flows through the first intake passage 1110 and the second intake passage 1120 in sequence. The intersection and connection between the first intake passage 1110 and the second intake passage 1120 makes it easier for the intake passage 1100 to receive gas.

[0062] Optionally, combined Figures 7 to 10 As shown, in some embodiments, the second air intake channel 1120 extends downward from the accommodating cavity 1500 (including but not limited to directly below and diagonally below), and the first air intake channel 1110 extends backward from the second air intake channel 1120 (including but not limited to directly behind and diagonally behind). The orientations in this document are based on the gas stove being in its installed and used state. With the user standing facing the gas stove, the side of the gas stove facing the user is front, the side away from the user is back, the side corresponding to the user's left hand is left, the side corresponding to the user's right hand is right, the side closest to the ground is bottom, and the side away from the ground is top. Since the first gas valve 3000 needs to be positioned at the front of the gas stove for easy user control, the gas inlet seat 1000 also needs to be positioned at the front to match the first gas valve 3000. Furthermore, since the gas inlet channel 1100 needs to be connected to the gas source, it generally requires a pipeline structure to achieve the connection with the gas source. Therefore, the second gas inlet channel 1120 extends downward from the accommodating cavity 1500 to avoid the control valve 2000, and the first gas inlet channel 1110 extends backward from the second gas inlet channel 1120 to facilitate connection with the gas source. This arrangement helps to reduce the space occupied by the gas control device. For example, the first gas inlet channel 1110 and the second gas inlet channel 1120 are perpendicular.

[0063] Combination Figures 11 to 14As shown, in some embodiments, the first gas outlet channel 1200 includes a first upstream channel 1210 and a first downstream channel 1220. That is, the first upstream channel 1210 is located upstream of the first downstream channel 1220. The first upstream channel 1210 is connected to the accommodating cavity 1500. The first downstream channel 1220 is intersecting and connected to the first upstream channel 1210. The first downstream channel 1220 is provided with a first outlet 1221. Gas flows through the first upstream channel 1210 and the first downstream channel 1220 in sequence. With this arrangement, it is more convenient to arrange the first gas valve 3000 and helps to reduce the space occupied by the gas control device. Similarly, in some embodiments, the auxiliary channel 1400 is connected to the first downstream channel 1220 (such as intersecting and connecting), which makes it easier to arrange the gas path and helps to make rational use of space. The gas entering the first upstream channel 1210 flows to the first downstream channel 1220, and the gas entering the auxiliary channel 1400 flows to the first downstream channel 1220 (the cross-sectional size of the first upstream channel 1210 can be set according to the firepower required for conventional heating).

[0064] Combination Figures 7 to 14 As shown, in some embodiments, the auxiliary channel 1400 protrudes into the accommodating cavity 1500, and the portion of the auxiliary channel 1400 protruding into the accommodating cavity 1500 is provided with an air inlet 1410. That is, the periphery of the air inlet 1410 is raised relative to the cavity wall of the accommodating cavity 1500, which makes it easier for the valve core 2200 to abut against the air inlet 1410 and to seal against the air inlet 1410. In particular, when the valve core 2200 abuts against the periphery of the air inlet 1410 through the sealing gasket 2210, it is more conducive to the deformation of the sealing gasket 2210 and forms a better sealing effect.

[0065] Since the second air intake channel 1120, the first upstream channel 1210, and the auxiliary channel 1400 are respectively connected to the accommodating cavity 1500, when machining the air intake seat 1000, the second air intake channel 1120, the first upstream channel 1210, and the auxiliary channel 1400 can be drilled through the accommodating cavity 1500 (the air intake port 1410 can be formed simultaneously when the auxiliary channel 1400 is drilled), there is no need to set hole structures elsewhere to drill the second air intake channel 1120, the first upstream channel 1210, and / or the auxiliary channel 1400, thus reducing the number of sealing points. For example, along the extension direction of the second intake passage 1120, the second intake passage 1120 may be exposed at the opening 1510 of the accommodating cavity 1500, and / or along the extension direction of the first upstream passage 1210, the first upstream passage 1210 may be exposed at the opening 1510 of the accommodating cavity 1500, and / or along the extension direction of the auxiliary passage 1400, the auxiliary passage 1400 may be exposed at the opening 1510 of the accommodating cavity 1500.

[0066] Similarly, since the first intake channel 1110 has an inlet 1111 and the first downstream channel 1220 has a first outlet 1221, drilling through the first intake channel 1110 will form the corresponding inlet 1111, and drilling through the first downstream channel 1220 will form the corresponding outlet 1221. Since the inlet 1111 is used to receive gas, and the first outlet 1221 is connected to the first gas valve 3000 to form a seal, there is no need to set up a hole structure elsewhere to drill through the first intake channel 1110 and / or the first downstream channel 1220, thus reducing the number of sealing points.

[0067] In some embodiments, the control valve 2000 is a solenoid valve, which can be a monostable solenoid valve or a bistable solenoid valve, to facilitate the movement of the valve core 2200 and thus realize the opening and closing of the air inlet 1410.

[0068] Combination Figures 3 to 14 As shown, in some embodiments, the air intake seat 1000 is further provided with a second air outlet channel 1300, which is adapted to communicate with the air intake channel 1100, and the second air outlet channel 1300 is blocked. Specifically, when the air intake seat 1000 is manufactured, it has an air intake channel 1100, a first air outlet channel 1200, a second air outlet channel 1300, and an auxiliary channel 1400. The second air outlet channel 1300 can be configured to be continuous or not continuous. When it is configured to be continuous and applied to a single-burner stove design, the second air outlet channel 1300 needs to be blocked. When it is configured to be not continuous and applied to a double-burner stove design, the second air outlet channel 1300 needs to be open. The following description uses the configuration of the second air outlet channel 1300 being continuous as an example. When the air intake 1000 is applied to a gas stove with a single-burner design (a single-burner means having one burner), the second gas outlet passage 1300 needs to be blocked. For example, by using screws to block the second gas outlet passage 1300, gas cannot be discharged through it. When the air intake 1000 is applied to a gas stove with a double-burner design (a double-burner means having two burners), the first gas outlet passage 1200 corresponds to the first gas valve 3000, which corresponds to the first burner. The second gas outlet passage 1300 corresponds to the second gas valve, which corresponds to the second burner. Gas can be discharged from both the first gas outlet passage 1200 and the second gas outlet passage 1300. In other words, once the air intake seat 1000 is manufactured, it can be used in both single-burner gas stove designs (requiring the second gas outlet channel 1300 to be blocked) and double-burner gas stove designs (without requiring the second gas outlet channel 1300 to be blocked). This eliminates the need to produce two different specifications of air intake seat 1000, increasing its versatility and helping to reduce costs.

[0069] The second aspect of this application discloses a gas stove, combined with Figures 1 to 14 As shown, the gas stove includes the aforementioned gas control device, which includes an inlet seat 1000, a control valve 2000, and a first gas valve 3000. The inlet seat 1000 is provided with an inlet channel 1100, a first outlet channel 1200, and an auxiliary channel 1400. The first outlet channel 1200 is connected to the inlet channel 1100, and the auxiliary channel 1400 is connected to the first outlet channel 1200 so that gas can flow from the auxiliary channel 1400 to the first outlet channel 1200. The auxiliary channel 1400 is provided with an inlet port 1410. The control valve 2000 is connected to the inlet seat 1000. The control valve 2000 includes a valve core 2200, which is movably configured to abut and disengage from the air inlet 1410. When the valve core 2200 abuts the air inlet 1410, the valve core 2200 closes the air inlet 1410. When the valve core 2200 disengages from the air inlet 1410, the valve core 2200 opens the air inlet 1410, thereby connecting the air inlet 1410 with the air intake passage 1100. The first gas valve 3000 is connected to the air intake seat 1000 and is connected to the first outlet 1221 of the first gas outlet passage 1200.

[0070] The first gas valve 3000 corresponds to the first burner and controls the gas supply to the first burner. By setting a first gas outlet channel 1200 and an auxiliary channel 1400 in the air inlet seat 1000, normal gas supply to the first gas valve 3000 can be achieved through the first gas outlet channel 1200 when the auxiliary channel 1400 is closed. When the auxiliary channel 1400 is open, gas supply to the first gas valve 3000 for stir-frying can be achieved through the auxiliary channel 1400 and the first gas outlet channel 1200. No structural modifications to the first gas valve 3000 are required; the first gas valve 3000 can use currently available mature products, offering strong compatibility and reducing structural complexity and cost. It is understood that the gas control device of the gas stove in this embodiment adopts the technical solution of the above embodiment, and therefore at least has the beneficial effects brought by the technical solution of the above embodiment, which will not be repeated here.

[0071] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
