Description

Technical Field

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

[0002] The flame produced by the burner head of a gas stove in the kitchen typically consists of two or more rings of fire. The size of the flame is mainly determined by the size of the outer rings of each layer. During use, the size of the rings needs to be adjusted to control the cooking temperature. In practice, when this heating method requires high heat, adjusting the rings of each layer to increase the heat takes a long time, making it unsuitable for stir-frying. This affects the flexibility of heating control and consequently the taste of the food. Utility Model Content

[0008] According to some embodiments of the present invention, a buffer insert is provided in the flow-dividing cavity, and the buffer insert is connected between the inner sidewall of the flow-dividing cavity and the outer sidewall of the flow guide platform.

[0009] According to some embodiments of the present invention, a diversion output hole is provided on the side wall of the diversion cavity, and the diversion output hole on the diversion cavity is connected to the output side of the first annular fire gas transmission channel. The gas in the guide cavity can pass through the diversion output hole and enter the output side of the first annular fire gas transmission channel.

[0010] The gas can pass sequentially through the diversion inlet, the diversion cavity, the guide platform opening, the guide cavity and the nozzle gas pipe into the central nozzle to achieve a stir-frying effect.

[0011] According to some embodiments of the present invention, a diversion output hole is provided on the side wall of the flow guide platform. The diversion output hole on the flow guide platform is connected to the output side of the first annular fire gas supply channel.

[0014] The gas control valve according to the embodiments of this utility model has at least the following technical effects:

[0015] 1. The switching on and off of the center nozzle and the firepower are controlled by the diversion solenoid valve on the diversion chamber. When the center nozzle does not need to be activated, the diversion solenoid valve drives the piston sealing part to block the opening of the guide platform, and the center nozzle is turned off. When the center nozzle needs to be activated to increase the firepower, the diversion solenoid valve drives the piston sealing part to open the opening of the guide platform, and the center nozzle is activated directly to enhance the flame.

[0017] 3. The function of the diversion solenoid valve independently controlling the gas supply to the central nozzle can be realized by opening a diversion output hole on the side wall of the diversion chamber and connecting it with the output side of the first ring flame gas supply channel. Alternatively, the function of the diversion solenoid valve simultaneously controlling the gas supply to the first ring flame cover and the central nozzle can be realized by opening a diversion output hole on the side wall of the guide platform and connecting it with the output side of the first ring flame gas supply channel. The design of the control method is more flexible.

[0019] The multi-ring flame gas stove according to the embodiments of this utility model has at least the following beneficial effects:

[0020] The gas stove's flame intensity is controlled by a diversion solenoid valve on the diversion chamber, which controls the switching on and off of the central nozzle. When the central nozzle is not needed, the diversion solenoid valve drives the piston sealing part to block the guide platform opening, and the central nozzle shuts off. When the central nozzle needs to be turned on to increase the flame intensity, the diversion solenoid valve drives the piston sealing part to open the guide platform opening, and the central nozzle starts to increase the flame, allowing for more flexible control of the gas stove's flame intensity.

[0038] The following is for reference. Figure 1 and Figure 2 A gas control valve according to an embodiment of the present utility model is described.

[0039] like Figure 1 and Figure 2 As shown, the gas control valve according to an embodiment of the present invention includes an air inlet chamber 100, a first ring flame cap 300, a center nozzle 500, a flow divider chamber 600, and a flow divider solenoid valve 700.

[0040] Intake chamber 100; First ring flame cap 300, which is connected to the intake chamber 100 via the first ring flame gas delivery channel 310; Center nozzle 500; Reference Figure 3 , Figure 4 The diversion chamber 600 is located on the first annular gas supply channel 310. A diversion input hole 601 is provided on the side wall of the diversion chamber 600, which is connected to the input side of the first annular gas supply channel 310. The diversion chamber 600 has a diversion chamber opening 610 on the left side. A guide platform 620 is provided inside the diversion chamber 600. A diversion cavity 611 is formed between the inner side wall of the diversion chamber 600 and the outer side wall of the guide platform 620. The guide platform 620 has a guide cavity 621. The guide platform 620 has a guide opening 622 on the left side. The guide cavity 621 is connected to the central nozzle 500 through the nozzle gas pipe 510. A diversion solenoid valve 700 is fitted onto the diversion chamber opening 610. The diversion solenoid valve 700 includes a valve stem 720, and a piston sealing part 721 is provided on the valve stem 720. The piston sealing part 721 can block the guide platform opening 622.

[0041] For example, such as Figure 1 and Figure 2 As shown, the intake chamber 100 is used to connect to an external gas source. The first annular flame cap 300 is connected to the intake chamber 100 through the first annular flame gas delivery passage 310. The first annular flame cap 300 has a flame outlet for flame emission. The central nozzle 500 also has a flame outlet for flame emission. The first annular flame cap 300 is positioned around the outer side of the central nozzle 500. (Refer to...) Figure 3 , Figure 4The first annular flame gas supply channel 310 is connected between the air inlet chamber 100 and the first annular flame cap 300, and is used to supply gas to the first annular flame cap 300. A diversion chamber 600 is located on the first annular flame gas supply channel 310 and is used to divert gas from the gas supply center nozzle 500 of the first annular flame gas supply channel 310. A diversion inlet hole 601 is provided on the side wall of the diversion chamber 600, which communicates with the inlet side of the first annular flame gas supply channel 310, allowing gas from the first annular flame gas supply channel 310 to enter the diversion chamber 600 through the diversion inlet hole 601. The diversion chamber 600 has a diversion chamber opening 610 on its left side. A guide platform 620 is provided inside the diversion chamber 600, and a diversion cavity 611 is formed between the inner side wall of the diversion chamber 600 and the outer side wall of the guide platform 620, allowing gas to enter the diversion cavity 611 within the diversion chamber 600. The flow guide platform 620 has a flow guide cavity 621, and a flow guide opening 622 on its left side. This allows the gas from the diversion cavity 611 to enter the flow guide cavity 621 within the flow guide platform 620 through the flow guide opening 622. The flow guide cavity 621 is connected to the central nozzle 500 via a nozzle pipe 510, allowing the gas within the flow guide cavity 621 to reach the central nozzle 500. The diversion solenoid valve 700 includes a valve body 710 and a valve stem 720. The valve body 710 covers the diversion cavity opening 610, effectively sealing the opening and preventing gas leakage from the diversion cavity 611. The valve stem 720 of the diversion solenoid valve 700 is extendable and retractable. A piston seal 721 is provided on the valve stem 720. The piston seal 721 can block the guide platform opening 622. That is, the piston seal 721 extends through the flow divider opening 610 into the flow divider cavity 611 and can extend and retract. When the piston seal 721 extends, it can block the guide platform opening 622. When the piston seal 721 retracts, it opens the guide platform opening 622.

[0042] This utility model's gas control valve serves as a burner control device, primarily controlling the on / off state of the central nozzle 500 and the flame intensity. The gas supplied to the central nozzle 500 originates from the intake chamber 100, enters the first annular combustion gas supply channel 310, and is then diverted through the diversion chamber 600.

[0043] In practical work, refer to Figure 7 After the gas source is connected to the intake chamber 100, gas is input and enters the first ring fire gas transmission channel 310. Then the gas in the first ring fire gas transmission channel 310 can enter the guide cavity 621 in the guide platform 620 through the diversion input hole 601.

[0044] When the center nozzle 500 does not need to be activated, the diversion solenoid valve 700 drives the valve stem 720 to extend, so that the piston seal 721 blocks the guide platform opening 622, and the gas will not flow to the center nozzle 500.

[0045] Because the central nozzle 500 adopts a direct injection gas outlet in the middle of the burner head, and its structure features enlarged air intake holes, it can supplement more air during gas outlet. Unlike the burner cap, which requires pre-mixing of air and gas before ring-shaped combustion, this avoids a reduction in gas pressure and is suitable for instantaneous high-intensity combustion. When it is necessary to open the central nozzle 500 to increase the firepower, the valve stem 720 is retracted by the diversion solenoid valve 700. This opens the guide platform opening 622 at the piston seal 721, allowing the gas to sequentially pass through the diversion inlet 601, the guide cavity 621, and the guide platform opening 622 into the guide cavity 621 of the guide platform 620. This allows a portion of the gas to be diverted through the nozzle gas pipe 510 to the central nozzle 500, enabling the central nozzle 500 to ignite and achieve increased firepower.

[0046] This allows the nozzle gas pipe 510 to become the center nozzle 500 by opening the diversion solenoid valve 700, achieving instant flame enhancement and enabling a one-button stir-fry function. The above process, by diverting the gas from the first ring flame gas supply channel 310 through the diversion chamber 600, eliminates the need for an additional gas source for the center nozzle 500. It also ensures that the heating of the center nozzle 500 and the first ring flame cap 300 does not conflict, effectively improving the combustion stability of the burner.

[0047] In some embodiments of this utility model, reference is made to Figure 1 This utility model relates to a gas control valve that controls the operation of a burner, which includes a first annular flame cap 300 and a second annular flame cap 400. The intake chamber 100 is connected to the first annular flame cap 300 via a first annular flame gas supply channel 310 and a first ejector tube 320, and to the second annular flame cap 400 via a second annular flame gas supply channel 410 and a second ejector tube 420, thus supplying gas to both the first and second annular flame caps 300. The diversion chamber 600, in conjunction with a diversion solenoid valve 700, only diverts the gas passing through the first annular flame gas supply channel 310, without affecting the gas in the second annular flame gas supply channel 410.

[0048] In some embodiments of this utility model, the first ring flame cap 300 is a first ring flame cap 300 cover structure as the outermost first ring flame cap 300 cover structure, the second ring flame cap 400 is a second ring flame cap structure, and the central nozzle 500 is located in the middle position.

[0049] In some embodiments of this utility model, the central nozzle 500 may adopt a high-power nozzle structure.

[0050] In some embodiments of this utility model, reference is made to Figure 2A first damper adjustment structure 330 is provided between the first annular gas supply channel 310 and the first ejector tube 320, which can adjust the amount of air entering the first ejector tube 320. A second damper adjustment structure 430 is provided between the second annular gas supply channel 410 and the second ejector tube 420, which can adjust the amount of air entering the second ejector tube 420.

[0051] In some embodiments of this utility model, reference is made to Figure 2 , Figure 3 The intake chamber 100 is equipped with a valve core assembly 200, an ignition micro switch 810, and a linkage micro switch 820. A flameout protection solenoid valve 830 is installed within the intake chamber 100. The ignition micro switch 810 is electrically connected to a pulse controller 840 and a timer 850, as is the linkage micro switch 820. The flameout protection solenoid valve 830 works in conjunction with the pulse controller 840 to control ignition. The timer 850 can be set to trigger the linkage micro switch 820. The valve core assembly 200 can control the ignition micro switch 810 and the linkage micro switch 820 via electrical connection or mechanical drive. The operator can manually activate the ignition micro switch 810 and the linkage micro switch 820 by operating the valve core assembly 200, thereby controlling the flameout protection solenoid valve 830 for ignition and controlling the diversion solenoid valve 700.

[0052] In some embodiments of this utility model, the valve core assembly 200 has a valve shaft 210, on which a rotating cam 220 is provided. The rotating cam 220 can rotate with the valve shaft 210. The rotating cam 220 has a first trigger point 221 and a second trigger point 222. The first trigger point 221 can trigger an ignition micro switch 810, and the second trigger point 222 can trigger a linkage micro switch 820. When the valve shaft 210 drives the rotating cam 220 to rotate to a first angle, the first trigger point 221 of the rotating cam 220 triggers the ignition micro switch 810, starting the flameout protection solenoid valve 830 to ignite. When the valve shaft 210 drives the rotating cam 220 to rotate to a second angle, the second trigger point 222 of the rotating cam 220 triggers the linkage micro switch 820, controlling the diversion solenoid valve 700 to ignite.

[0053] The first angle and the second angle can be the same angle or different angles.

[0054] In some embodiments of this utility model, a connecting plate 110 is provided on the upper side of the air intake chamber 100, and the ignition micro switch 810 and the linkage micro switch 820 are connected to the connecting plate 110 to facilitate the installation of the ignition micro switch 810 and the linkage micro switch 820.

[0055] In some embodiments of this utility model, reference is made to Figure 4 , Figure 5 A buffer insert 612 is provided inside the flow-dividing cavity 611. The buffer insert 612 is connected between the inner wall of the flow-dividing cavity 600 and the outer wall of the guide platform 620, which means that the buffer insert 612 plays a buffering role on the airflow in the flow-dividing cavity 611. The gas flow entering the flow-dividing cavity 611 from the flow-dividing inlet 601 is buffered by the buffer insert 612, ensuring that the gas flow fills the flow-dividing cavity 611 before entering the guide platform opening 622 under the control of the flow-dividing solenoid valve 700. This ensures the stability of the combustion of the central nozzle 500 and avoids the phenomenon of the flame of the central nozzle 500 fluctuating in size.

[0056] In some embodiments of this utility model, referring to 4, a diversion output hole 613 is provided on the side wall of the diversion cavity 600. The diversion output hole 613 is connected to the output side of the first annular gas transmission channel 310. The gas in the guide cavity 621 can pass through the diversion output hole 613 and enter the output side of the first annular gas transmission channel 310. That is, the gas entering the diversion cavity 600 from the input side of the first annular gas transmission channel 310 can be discharged through the diversion output hole 613 on the side wall of the diversion cavity 600 and then re-enter the output side of the first annular gas transmission channel 310.

[0057] The gas can pass through the diversion inlet 601, the diversion cavity 611, the guide platform opening 622, the guide cavity 621 and the nozzle gas pipe 510 in sequence and enter the central nozzle 500 to achieve the stir-frying effect.

[0058] Reference Figure 7 When the center nozzle 500 does not need to be activated, the diversion solenoid valve 700 drives the valve stem 720 to extend. After the piston sealing part 721 blocks the guide platform opening 622, the gas will not flow into the guide platform 620 to supply gas to the center nozzle 500. However, it can still be discharged through the flow output hole 613 and re-enter the first ring flame gas supply channel 310 to supply gas to the first ring flame cover 300.

[0059] When it is necessary to open the center nozzle 500 to increase the firepower, the piston sealing part 721 is driven by the diversion solenoid valve 700 to open the guide platform opening 622, and then the gas can flow into the guide platform 620 to supply gas to the center nozzle 500, without affecting the first ring flame gas supply channel 310 to supply gas to the first ring flame cover 300.

[0060] This is equivalent to enabling the flow divider solenoid valve 700 to independently control the central nozzle 500 for air supply.

[0061] In some embodiments of this utility model, reference is made to Figure 5A diversion output hole 613 is provided on the side wall of the guide platform 620. The diversion output hole 613 is connected to the output side of the first annular gas supply channel 310. The gas in the diversion cavity 611 can pass through the diversion output hole 613 and enter the output side of the first annular gas supply channel 310. That is, the gas entering the diversion cavity 600 from the input side of the first annular gas supply channel 310 must be discharged through the diversion output hole 613 on the side wall of the guide platform 620 and then re-enter the output side of the first annular gas supply channel 310.

[0062] Reference Figure 8 When the center nozzle 500 does not need to be activated, the diversion solenoid valve 700 drives the valve stem 720 to extend, so that the piston sealing part 721 blocks the guide platform opening 622, and the gas will not flow into the guide platform 620, so that it can neither supply gas to the center nozzle 500 nor to the first ring flame cap 300.

[0063] When it is necessary to open the center nozzle 500 to increase the firepower, the valve stem 720 is driven to retract by the diversion solenoid valve 700. In this way, the piston seal 721 opens the guide platform opening 622, and the gas can flow into the guide platform 620, which can supply gas to both the center nozzle 500 and the first ring flame cap 300.

[0064] This is equivalent to enabling the diversion solenoid valve 700 to simultaneously control the gas supply to the first ring flame cap 300 and the center nozzle 500.

[0065] In some embodiments of this utility model, the diversion solenoid valve 700 is electrically connected to a temperature sensor. This allows the temperature sensor to sense the temperature of the cookware. When the cookware reaches the set maximum temperature, a signal is sent to the diversion solenoid valve 700 to shut off the first ring flame cover 300, leaving only the center nozzle 500 for cooking. If the temperature drops to the set minimum temperature, a signal is sent to the diversion solenoid valve 700 to open the first ring flame cover 300 for heating, thereby ensuring that the cooking temperature is within the set requirements.

[0066] In some embodiments of this utility model, the diversion solenoid valve 700 is electrically connected to a pressure sensor. When the cookware is removed without turning off the stove, the pressure sensor senses the change in the pressure on the stove head and sends a signal back to the diversion solenoid valve 700 to shut off the first ring flame cover 300, leaving only the central nozzle 500 open. This avoids excessive flames from posing a safety hazard to the user and effectively reduces gas waste. When the cookware is placed back on the stove head, the solenoid valve 21 opens the first ring flame cover 300 for use, eliminating the need for the user to restart the stove, making it convenient to use.

[0067] In some embodiments of this utility model, the diversion solenoid valve 700 is electrically connected to an infrared sensor, which senses the distance and temperature between the cookware and the burner head, thereby realizing the above-mentioned function of starting and stopping the first ring cover 300.

[0068] In some embodiments of this utility model, a controller is installed on the nozzle gas pipe 510 that connects to the central nozzle 500. For example, if the water in the pot dries up during the boiling process and the pot temperature is too high, the controller will use the diversion solenoid valve 700 to simultaneously shut off the central nozzle 500 and the first ring flame cover 300, thereby preventing the pot from "dry burning".

[0069] In some embodiments of this utility model, a nozzle inlet 624 is provided on the side wall of the guide platform 620, and a nozzle air pipe connector 640 is provided outside the air inlet chamber 100. The nozzle inlet 624 is connected to the nozzle air pipe connector 640. In this way, the nozzle air pipe 510 and the nozzle air pipe connector 640 can be connected together, so that the gas in the guide platform 620 can be delivered from the nozzle inlet 624 through the nozzle air pipe connector 640 and the nozzle air pipe 510 to the position of the central nozzle 500.

[0070] In some embodiments of this utility model, reference is made to Figure 6 A return spring 723 is fitted on the valve stem 720. The two ends of the return spring 723 press against the valve body 710 and the piston sealing part 721 respectively. In this way, the return spring 723 provides a thrust to the piston sealing part 721, which serves as the return force of the piston sealing part 721 and also ensures that the piston sealing part 721 can press and seal the guide platform opening 622.

[0071] In some embodiments of this utility model, reference is made to Figures 4-6 A guide platform sealing boss 623 is provided on the edge of the guide platform opening 622, and a sealing gasket 722 is fitted on the piston sealing part 721. The sealing gasket 722 can press against the guide platform sealing boss 623, so as to ensure that when the piston sealing part 721 presses and seals the guide platform opening 622, it is sufficiently sealed to avoid leakage between the diversion cavity 611 and the guide cavity 621, which would affect the control effect of the diversion solenoid valve 700.

[0072] In some embodiments of this utility model, reference is made to Figure 1 , Figure 2The burner of this invention also includes a second annular flame cap 400 and a second annular flame gas supply channel 410. The second annular flame gas supply channel 410 is connected between the air inlet chamber 100 and the second annular flame cap 400. A gas distribution channel 630 is connected between the guide platform 620 and the second annular flame gas supply channel 410, allowing the gas in the guide cavity 621 to pass through the gas distribution channel 630 and enter the second annular flame gas supply channel 410. Thus, when it is necessary to open the central nozzle 500 to increase the firepower, the valve stem 720 is retracted by the diversion solenoid valve 700, which opens the guide platform opening 622, allowing the gas to flow into the guide platform 620. The gas in the guide platform 620 can then supply gas to the central nozzle 500 or, through the gas distribution channel 630, enter the second annular flame gas supply channel 410 to increase the gas supply to the second annular flame cap 400.

[0073] In some embodiments of this invention, the flameout protection solenoid valve 830 has a thermocouple circuit or a thermocouple induction probe as a flameout protection device. When the flame is burning, the voltage difference generated by the thermocouple of the flameout protection device drives the solenoid coil of the flameout protection solenoid valve 830, generating a magnetic field that attracts the valve body and keeps the valve open. Once the flame is extinguished, the thermoelectric effect of the thermocouple disappears, the solenoid coil loses its driving current, and the valve quickly closes, achieving safe gas shut-off. This design effectively ensures the safe use of the gas stove.

[0074] A multi-ring flame gas stove according to a second aspect of the present invention includes a gas control valve according to the first aspect of the present invention described above.

[0075] According to the embodiments of the present invention, the multi-ring flame gas stove reduces the thickness of the multi-ring flame gas stove by adopting the above-mentioned gas control valve, which facilitates the one-button ignition design of the gas stove and improves the combustion control effect of the multi-ring flame, thereby enhancing the user experience.
