Description

Technical Field

[0001] This invention relates to the field of gas stove technology, specifically to a gas valve and a gas stove. Background Technology

[0002] A gas stove is a kitchen appliance that uses gaseous fuels such as liquefied petroleum gas, manufactured gas, and natural gas for direct-fire heating. Currently, gas stoves have been developed with burners featuring dual or multi-ring flames, which makes the bottom of the pot heated more evenly and greatly improves the heat output.

[0003] In related technologies, a dual-ring gas stove includes an inlet pipe, a valve body, an inner ring gas distribution pipe, an outer ring gas distribution pipe, and a burner. The valve body has a sliding channel, and an inlet, an inner ring outlet, and an outer ring outlet connected to the sliding channel. A valve stem passes through the sliding channel. The inlet is connected to the inlet pipe, and the inner ring outlet is connected to the inner ring gas distribution pipe, which supplies gas to the inner ring of the burner. The outer ring outlet is connected to the outer ring gas distribution pipe, which supplies gas to the outer ring of the burner. Gas in the inlet pipe enters the sliding channel through the inlet. By rotating the valve stem, the amount of gas flowing out from the inner ring outlet and the outer ring outlet can be adjusted simultaneously, thereby increasing or decreasing the flame intensity of the inner and outer rings simultaneously.

[0004] However, rotating the valve stem can only increase or decrease the inner and outer ring firepower simultaneously, and cannot achieve individual adjustment of the inner and outer ring firepower, thus failing to meet the diverse needs of users for inner and outer ring firepower. Summary of the Invention

[0005] The main objective of this invention is to provide a gas valve and a gas stove to solve the problem that related gas valves cannot adjust the inner ring firepower and outer ring firepower separately.

[0006] To achieve the above objectives, embodiments of the present invention provide a gas valve, comprising: a valve body, an inner ring valve assembly, and an outer ring valve assembly. The valve body has a valve cavity, and an inlet channel, an inner ring outlet channel, and an outer ring outlet channel communicating with the valve cavity. The inner ring valve assembly and the outer ring valve assembly are rotatably disposed within the valve cavity. The inner ring valve assembly controls the flow area between the valve cavity and the inner ring outlet channel, and the outer ring valve assembly controls the flow area between the valve cavity and the outer ring outlet channel.

[0007] In the preferred embodiment of the gas valve described above, the outer ring valve assembly includes an outer ring valve stem, which is rotatably inserted into the valve cavity, and a portion of the outer ring valve stem extends outside the valve cavity. An outer ring gas passage is provided on the outer ring valve stem within the valve cavity, and the outer ring gas passage communicates with the inlet passage.

[0009] In the preferred embodiment of the above-mentioned gas valve, the inner ring valve assembly includes an inner ring valve stem and an inner ring adjusting column. The inner ring valve stem is parallel to the axis of the outer ring valve stem, and the inner ring valve stem passes through the outer ring valve stem, with both ends extending outside the outer ring valve stem. The inner ring adjusting column is rotatably inserted into the valve cavity and is connected to the inner ring valve stem. An inner ring gas passage is provided on the inner ring adjusting column, which communicates with the inlet gas passage. When the inner ring valve stem rotates to a second preset angle, the inner ring gas passage communicates with the inner ring outlet gas passage.

When the control switch is opened, the control valve controls the air intake channel to open. A control plate is disposed on the outer ring valve stem located outside the valve cavity. The control plate is perpendicular to the axis of the outer ring valve stem. The control plate is located above the control switch, and there is a preset gap between the control plate and the control switch. The outer ring valve stem can move toward the inner ring adjusting column so that the control plate abuts against the control switch and activates the control switch.

[0012] In the preferred embodiment of the gas valve described above, the inner ring adjusting column and the outer ring valve stem are spaced apart, and an outer ring return spring is provided between the inner ring adjusting column and the outer ring valve stem. The outer ring return spring is used to apply a spring force to the outer ring valve stem in a direction away from the inner ring adjusting column, so as to separate the control plate from the control switch.

[0013] In the preferred embodiment of the gas valve described above, the inner ring valve stem and the inner ring adjusting column are slidably connected, and the sliding direction of the inner ring valve stem relative to the inner ring adjusting column is parallel to the axis of the inner ring valve stem.

This is only for the convenience of description and is not intended to indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the embodiments of the present invention.

[0043] Furthermore, it should be noted that, in the description of the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] The dual-ring gas stove includes a burner, an inlet pipe, a valve body, an inner ring gas distribution pipe, and an outer ring gas distribution pipe. The burner includes a burner head, and an inner ring burner cap and an outer ring burner cap covering the burner head. The outer ring burner cap is fitted outside the inner ring burner cap, and the axes of the inner ring burner cap and the outer ring burner cap are collinear. The burner head includes an outer ring injector pipe and an inner ring injector pipe. The outer ring injector pipe supplies gas to the outer ring burner cap, and the inner ring injector pipe supplies gas to the inner ring burner cap.

[0046] The valve body has a sliding channel, and an air inlet, an inner ring air outlet, and an outer ring air outlet connected to the sliding channel. A valve stem passes through the sliding channel. The air inlet is connected to the air inlet pipe; the inner ring air outlet is connected to the inner ring gas distribution pipe, which supplies gas to the inner ring injector pipe; the outer ring air outlet is connected to the outer ring gas distribution pipe, which supplies gas to the outer ring injector pipe. The valve stem has an inner ring gas passage and an outer ring gas passage, both of which are connected to the sliding channel. When the valve stem rotates to a preset angle, the inner ring gas passage is also connected to the inner ring air outlet, and the outer ring gas passage is also connected to the outer ring air outlet.

[0047] Gas enters the sliding channel from the intake pipe. By rotating the valve stem, the amount of gas flowing out from the inner ring outlet and the outer ring outlet can be adjusted simultaneously, thereby increasing or decreasing the inner ring firepower and the outer ring firepower at the same time.

[0048] However, rotating the valve stem can only increase or decrease the inner and outer ring firepower simultaneously, and cannot achieve individual adjustment of the inner and outer ring firepower. In other words, it cannot achieve the same effect as decreasing the inner ring firepower while increasing the outer ring firepower, or increasing the inner ring firepower while decreasing the outer ring firepower, and thus cannot meet the diverse needs of users for inner and outer ring firepower.

[0049] This embodiment provides a gas valve and a gas stove. By setting an inner ring valve assembly and an outer ring valve assembly in the valve cavity, the inner ring valve assembly is used to control the inner ring firepower, and the outer ring valve assembly is used to control the outer ring firepower, thereby realizing the individual adjustment of the inner ring firepower and the outer ring firepower.

[0050] The principles and features of the embodiments of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the embodiments of the present invention and are not intended to limit the scope of the embodiments of the present invention.

[0051] The gas stove provided in this embodiment of the invention includes an inlet pipe, a gas valve, an inner ring gas distribution pipe, an outer ring gas distribution pipe, and a burner, such as... Figure 1 As shown, the gas valve includes a valve body 100, an inner ring valve assembly, and an outer ring valve assembly, as follows: Figure 2 As shown, the valve body 100 has a valve cavity 101, an air inlet channel 102, an inner ring air outlet channel 103 and an outer ring air outlet channel 104. The air inlet channel 102, the inner ring air outlet channel 103 and the outer ring air outlet channel 104 are all connected to the valve cavity 101. The inner ring valve assembly and the outer ring valve assembly are rotatably installed in the valve cavity 101.

[0052] The intake pipe is connected to the intake channel 102. The gas in the intake pipe enters the valve chamber 101 from the intake channel 102. The flow area between the valve chamber 101 and the inner ring outlet channel 103 is controlled by rotating the inner ring valve assembly. The flow area between the valve chamber 101 and the outer ring outlet channel 104 is controlled by rotating the outer ring valve assembly.

[0053] The inner ring air outlet channel 103 is connected to one end of the inner ring air distribution pipe, and the outer ring air outlet channel 104 is connected to one end of the outer ring air distribution pipe.

[0054] The burner includes a burner head, an inner ring burner cap, and an outer ring burner cap. The burner head includes a burner cap seat, an inner ring injector tube, and an outer ring injector tube. Both the inner and outer ring burner caps cover the burner cap seat, and the outer ring burner cap is fitted over the inner ring burner cap. The axes of the inner and outer ring burner caps are collinear. Both the inner and outer ring injector tubes are connected to the burner cap seat. The other end of the inner ring gas distribution pipe is connected to the inner ring injector tube so that the inner ring injector tube supplies fuel gas and air to the inner ring burner cap. The other end of the outer ring gas distribution pipe is connected to the outer ring injector tube so that the outer ring injector tube supplies fuel gas and air to the outer ring burner cap.

[0055] The inner ring valve assembly controls the flow area between the valve chamber 101 and the inner ring outlet channel 103, thereby controlling the amount of gas entering the inner ring gas distribution pipe and the inner ring injector, ultimately controlling the intensity of the inner ring flame. The outer ring valve assembly controls the flow area between the valve chamber 101 and the outer ring outlet channel 104, thereby controlling the amount of gas entering the outer ring gas distribution pipe and the outer ring injector, ultimately controlling the intensity of the outer ring flame. The inner ring flame is adjusted by the inner ring valve assembly, and the outer ring flame is adjusted by the outer ring valve assembly, thus achieving independent control of the inner and outer ring flames.

[0056] like Figure 3 As shown, in some embodiments, the outer ring valve assembly includes an outer ring valve stem 210, which is rotatably inserted into the valve cavity 101, and a portion of the outer ring valve stem 210 extends outside the valve cavity 101. An outer ring air passage 211 is provided on the outer ring valve stem 210 inside the valve cavity 101. The outer ring air passage 211 is connected to the air inlet passage 102. When the outer ring valve stem 210 rotates at a first preset angle, the outer ring air passage 211 is connected to the outer ring air outlet passage 104.

[0057] The outer ring air passage 211 can have various structural forms; refer to [reference here]. Figure 3 In some implementations, an outer ring vent groove 212 may be provided on the end face of the outer ring valve stem 210 located in the valve cavity 101. An outer ring vent hole 213 is provided on the groove wall of the outer ring vent groove 212. The outer ring vent groove 212 and the outer ring vent hole 213 constitute an outer ring vent channel 211. The outer ring vent hole 213 is connected to the outer ring vent channel 104 when the outer ring valve stem 210 rotates at a first preset angle.

[0058] In some other implementations, a notch may be provided on the outer wall of the outer ring valve stem 210 located in the valve cavity 101. The notch penetrates the end face of the outer ring valve stem 210 located in the valve cavity 101. The notch forms an outer ring air passage 211. The notch is always connected to the air intake passage 102, and the notch is connected to the outer ring air outlet passage 104 when the outer ring valve stem 210 rotates at a first preset angle.

[0059] Continue to refer to Figure 3 The inner ring valve assembly includes an inner ring valve stem 310 and an inner ring adjusting column 320. The inner ring valve stem 310 is parallel to the axis of the outer ring valve stem 210, and the inner ring valve stem 310 passes through the outer ring valve stem 210, with both ends of the inner ring valve stem 310 extending outside the outer ring valve stem 210. The inner ring adjusting column 320 is rotatably inserted into the valve cavity 101 and is connected to the inner ring valve stem 310. An inner ring air passage 321 is provided on the inner ring adjusting column 320, which communicates with the air inlet passage 102. When the inner ring valve stem 310 rotates to a second preset angle, the inner ring air passage 321 communicates with the inner ring air outlet passage 103.

[0060] The inner ring air passage 321 can have various structural forms, such as Figure 4 As shown, in some implementations, the inner ring adjusting column 320 can be tubular, with its axis collinear with the axis of the valve chamber 101. The air intake channel 102 is connected to the end of the inner ring adjusting column 320 away from the outer ring valve stem 210. An inner ring air outlet 322 is provided on the tube wall of the inner ring adjusting column 320, and the inner ring air outlet 322 is connected to the inner ring air outlet channel 103 when the inner ring valve stem 310 rotates to a second preset angle.

[0061] In other implementations, an inner ring air passage groove can be provided on the end face of the inner ring adjusting column 320 facing the outer ring valve stem 210. The opening of the inner ring air passage groove is directly opposite the opening of the outer ring air passage groove 212. The inner ring air outlet 322 can be provided on the groove wall of the inner ring air passage groove. The spaced arrangement between the inner ring adjusting column 320 and the outer ring valve stem 210 allows the air intake channel 102 to communicate with the valve cavity 101 between the inner ring adjusting column 320 and the outer ring valve stem 210. The air intake channel 102 communicates with the outer ring air outlet 213 through the outer ring air passage groove 212 and with the inner ring air outlet through the inner ring air passage groove.

[0062] Continue to refer to Figure 1 and Figure 3 In some embodiments, the gas valve may further include a control switch 410 and a control valve 420. The control switch 410 is electrically connected to the control valve 420. The control switch 410 may be a micro switch or other switch that can control the control valve 420. The control valve 420 may be a solenoid valve or other switch that can control the opening or closing of the air intake passage 102.

[0063] The control switch 410 can be installed on the valve body 100. A control plate 214 is installed on the outer ring valve stem 210 outside the valve cavity 101. The control plate 214 is perpendicular to the axis of the outer ring valve stem 210. The control plate 214 is located above the control switch 410, and there is a preset gap between the control plate 214 and the control switch 410. The outer ring valve stem 210 can move toward the inner ring adjusting column 320 so that the control plate 214 abuts against the control switch 410 and activates the control switch 410.

[0064] Continue to refer to Figure 3 The control valve 420 can be installed on the intake passage 102. When the control switch 410 is opened, the control valve 420 controls the intake passage 102 to open, so that the gas enters the inner ring gas passage 321 and the outer ring gas passage 211 from the intake passage 102.

[0065] The outer ring valve stem 210 can be positioned above the inner ring adjusting column 320. When the gas valve is in use, pressing down on the outer ring valve stem 210 causes the control plate 214 to contact and activate the control switch 410. The control valve 420 then opens the intake passage 102, allowing gas to enter the inner ring gas passage 321 and the outer ring gas passage 211. Rotating the outer ring valve stem 210 adjusts the flow area between the outer ring outlet 213 and the outer ring outlet passage 104, thereby adjusting the outer ring flame intensity. Rotating the inner ring valve stem 310 adjusts the flow area between the inner ring outlet 322 and the inner ring outlet passage 103, thereby adjusting the inner ring flame intensity.

[0066] Continue to refer to Figure 3 and Figure 5 In some embodiments, an outer ring return spring 220 is provided between the inner ring adjusting column 320 and the outer ring valve stem 210. One end of the outer ring return spring 220 abuts against the end face of the outer ring valve stem 210, and the other end of the outer ring return spring 220 abuts against the end face of the inner ring adjusting column 320. The outer ring return spring 220 is used to apply a spring force to the outer ring valve stem 210 in a direction away from the inner ring adjusting column 320, so that the control plate 214 separates from the control switch 410 after the control switch 410 is activated.

[0067] In some embodiments, the inner ring valve stem 310 is slidably connected to the inner ring adjusting column 320, and the sliding direction of the inner ring valve stem 310 relative to the inner ring adjusting column 320 is parallel to the axis of the inner ring valve stem 310.

[0068] Specifically, such as Figure 6 As shown, a sliding rod 313 can be provided at one end of the inner ring valve stem 310 near the inner ring adjusting column 320, and the axis of the sliding rod 313 is perpendicular to the axis of the inner ring valve stem 310. (Continue referring to...) Figure 4A sliding groove can be provided on the inner tube wall of the inner ring adjusting column 320. The extension direction of the sliding groove is parallel to the axis of the inner ring adjusting column 320. The sliding rod 313 is slidably disposed in the sliding groove, and the sliding rod 313 can slide in the sliding groove along the axis of the inner ring valve rod 310.

[0069] Furthermore, the sliding groove can penetrate the end face of the inner ring adjusting column 320 facing the outer ring valve stem 210. When installing the sliding rod 313 and the inner ring adjusting column 320, the sliding rod 313 can be directly inserted into the sliding groove from the end of the sliding groove that is close to the outer ring valve stem 210. When it is necessary to remove the sliding rod 313 from the inner ring adjusting column 320, the sliding rod 313 can simply be slid out of the sliding groove.

[0070] Continue to refer to Figure 4 The sliding groove may include a first sliding groove 323 and a second sliding groove 324, with the first sliding groove 323 and the second sliding groove 324 facing each other. One end of the sliding rod 313 is slidably disposed in the first sliding groove 323, and the other end of the sliding rod 313 is slidably disposed in the second sliding groove 324, so that the sliding rod 313 is not easily disengaged from the inner ring adjusting column 320.

[0071] When it is necessary to activate the control switch 410, the outer ring valve stem 210 and the inner ring valve stem 310 can be pressed down simultaneously. Since the inner ring valve stem 310 passes through the outer ring valve stem 210, it is difficult to operate by only pressing down the outer ring valve stem 210. Pressing down the outer ring valve stem 210 and the inner ring valve stem 310 simultaneously makes operation easier.

[0072] like Figure 7 and Figure 8 As shown, an outer ring knob 216 can be provided at the top of the outer ring valve stem 210, and an inner ring knob 314 can be provided at the top of the inner ring valve stem 310. The outer ring knob 216 can be ring-shaped, and the bottom end of the outer ring knob 216 is bent inward to form a bent edge. The inner ring knob 314 can be column-shaped, and the inner ring knob 314 can be inserted inside the outer ring knob 216, with the inner ring knob 314 located above the bent edge. The bottom of the inner ring knob 314 can be provided with a snap-fit ​​part, and the side of the bent edge facing the inner ring knob 314 can be provided with a mating part. When the inner ring valve stem 310 and the outer ring valve stem 210 are pressed down at the same time, the snap-fit ​​part and the mating part snap together, so that the inner ring valve stem 310 and the outer ring valve stem 210 can rotate simultaneously.

[0073] Continue to refer to Figure 8 Furthermore, in some implementations, the snap-fit ​​part can be a snap-fit ​​block 315, and the mating part can be a snap-fit ​​groove 217. There can be multiple snap-fit ​​grooves 217, which are equally spaced around the axis of the inner ring valve stem 310.

[0074] In other implementations, the snap-fit ​​part can be a snap-fit ​​slot, and the mating part can be a snap-fit ​​block.

[0075] Continue to refer to Figure 3 The outer ring valve stem 210 has a receiving groove 215 on the end face of the end outside the valve cavity 101. The inner ring valve stem 310 has a stop plate 311 on the end outside the valve cavity 101. An inner ring return spring 312 is sleeved on the inner ring valve stem 310. One end of the inner ring return spring 312 abuts against the stop plate 311, and the other end of the inner ring return spring 312 abuts against the bottom of the receiving groove 215. The inner ring return spring 312 is used to apply a spring force to the stop plate 311 in a direction away from the inner ring adjusting column 320, so that after the control plate 214 touches the control switch 410, the axis of the inner ring air outlet 322 and the axis of the inner ring air outlet channel 103 are in the same plane.

[0076] Besides the implementation where the control plate 214 is mounted on the outer ring valve stem 210, in other implementations, the control plate 214 can also be mounted on the inner ring valve stem 310 located outside the valve cavity 101. The control plate 214 can be perpendicular to the axis of the inner ring valve stem 310. A mating hole can be provided on the outer ring valve stem 210 opposite to the control plate 214, and the control plate 214 passes through the mating hole and extends outside the outer ring valve stem 210. The control plate 214 outside the outer ring valve stem 210 can be located above the control switch 410, and there is a preset gap between the control plate 214 and the control switch 410. When the inner ring valve stem 310 moves towards the inner ring adjusting column 320, the control plate 214 can abut against the control switch 410 and activate the control switch 410.

[0077] The inner ring valve stem 310 can be pressed down, or the inner ring valve stem 310 and the outer ring valve stem 210 can be pressed down simultaneously to make the control plate 214 come into contact with the control switch 410 and activate the control switch 410.

[0078] In other embodiments, the valve cavity 101 may be V-shaped or U-shaped. The inner ring valve assembly may include an inner ring valve stem 310, which passes through one end of the valve cavity 101 and extends partially to the outside of the valve cavity 101.
