Description

Technical Field

[0001] This application relates to the technical field of kitchen appliances, and particularly to a gas stove. Background Art

[0002] Currently, intelligent cooking has gradually become the focus of the development of gas stoves. Intelligent cooking gas stoves usually have two control methods: intelligent adjustment and manual adjustment. Intelligent adjustment controls the cooking temperature and cooking time of the gas stove through touch screen operation or remote operation, and is realized by an automatic control valve body controlling the gas intake volume and intake time; while manual adjustment controls the gas intake volume and intake time through a traditional mechanical control valve body.

[0003] Therefore, the intake pipe of an intelligent cooking gas stove has different air inlets: the air inlet of the automatic control valve body and the air inlet of the mechanical control valve body. In the prior art, most of the air inlets of the automatic control valve body are at the rear side of the valve body, and most of the air inlets of the mechanical control valve body are at the upper side of the valve body. That is to say, the plane of the air inlet of the automatic control valve body of the intake pipe is perpendicular to the horizontal plane, and the plane of the air inlet of the mechanical control valve body is parallel to the horizontal plane, and the planes where they are located are different; at the same time, the heights of the automatic control valve and the mechanical control valve are different, resulting in different heights of the air inlets.

[0004] For most intelligent cooking gas stoves, the intake pipe is processed by bending, which increases the manufacturing difficulty of the intake pipe. At the same time, multiple bends increase the accumulation of dimensional errors, resulting in a large final dimensional deviation, and the intake pipe cannot be normally assembled. Summary of the Utility Model

[0005] This application provides a gas stove, which is used to solve the problem that due to the different positions of the valve bodies of the gas stove, the intake pipe needs to be bent multiple times during the processing, resulting in difficult manufacturing and reduced assembly accuracy.

[0006] To achieve the above object, this application adopts the following technical solutions:

[0007] This application provides a gas stove, including: a burner and an intake pipe assembly. The intake pipe assembly is communicated with the burner and is used to deliver gas to the burner. Among them, the burner includes a first burner and a second burner, and the intake pipe assembly includes: a first gas pipeline, a second gas pipeline, a mechanical valve, an automatic control valve, and a connecting member. The mechanical valve is provided with an air inlet and an air outlet. The air inlet is communicated with the first gas pipeline, and the air outlet is communicated with the first burner; the automatic control valve is provided with an air intake hole and an air outlet hole. The air intake hole is communicated with the second gas pipeline, and the air outlet hole is communicated with the second burner; the connecting member is internally provided with a gas transmission chamber, and the connecting member is connected between the first gas pipeline and the second gas pipeline, so that the gas in the first gas pipeline enters the second gas pipeline through the gas transmission chamber.

[0008] In the gas stove provided by the present application, the gas flowing out of the external gas pipeline is divided into two paths through the first gas pipeline. One of the paths flows through the air inlet of the mechanical valve and then flows out of the air outlet into the first burner, thereby providing gas for the first burner. The other path flows through the first gas pipeline to the gas transmission chamber of the connecting part, then flows into the second gas pipeline, and finally flows through the air inlet hole and the air outlet hole of the automatic control valve in sequence to the second burner.

[0009] Since the connecting part is connected between the first gas pipeline and the second gas pipeline, in this way, if the heights of the first gas pipeline and the second gas pipeline are different, they can be misaligned and connected to the connecting part. Compared with the prior art, there is no need to process the inlet gas pipeline by bending. Thus, the manufacturing difficulty is reduced, and the assembly accuracy of the inlet gas pipeline assembly is ensured.

[0010] In some embodiments of the present application, the first gas pipeline may include: a first air inlet, a first gas transmission channel, and a first air outlet. Among them, the first air inlet is used to communicate with the external gas pipeline, the first gas transmission channel is communicated with the first air inlet, and the first air outlet is communicated between the gas transmission chamber and the first gas transmission channel; the air inlet of the mechanical valve is communicated between the first air inlet and the first air outlet.

[0011] In this way, the gas can enter the first gas transmission channel through the first air inlet, and through the transmission of the first gas transmission channel, enter the gas transmission chamber of the connecting part through the first air outlet.

[0012] In some embodiments of the present application, a first air outlet hole may also be provided on the first gas pipeline. The first air outlet hole is communicated with the first gas transmission channel; the air inlet of the mechanical valve is communicated with the first air outlet hole; the central axis of the first air outlet hole is perpendicular to the extension direction of the first gas pipeline.

[0013] In this way, the gas in the first gas pipeline can enter the first burner through the first air outlet hole, the air inlet of the mechanical valve, and the air outlet of the mechanical valve in sequence. The mechanical valve can be used to control the on-off of the gas flowing to the first burner.

[0014] In some embodiments of the present application, a first air hole and a second air hole communicated with the gas transmission chamber are opened on the connecting part. The first air hole is communicated with the first air inlet, the second air hole is communicated with the second gas pipeline, and the first air hole and the second air hole are located on two opposite walls of the connecting part.

[0015] The heights of the first air hole and the second air hole can be different. In this way, the first gas pipeline and the second gas pipeline can be connected at different heights.

[0016] In some embodiments of the present application, the second gas pipeline may include: a second air inlet, a second gas transmission channel, and a second air outlet. Among them, the second air inlet is communicated with the second air hole, the second gas transmission channel is communicated with the second air inlet, and the second air outlet is communicated with the second gas transmission channel; the air inlet hole of the automatic control valve is communicated between the second air inlet and the second air outlet.

[0017] In this way, the gas can enter the second gas transmission channel from the gas transmission chamber of the connecting member through the second air inlet.

[0018] In some embodiments of the present application, a second air outlet hole may also be provided on the second gas pipeline. The second air outlet hole is communicated with the second gas transmission channel and is located between the second air inlet and the second air outlet; the air inlet hole of the automatic control valve is communicated with the second air outlet hole.

[0019] Among them, the central axis of the second air outlet hole on the second gas pipeline is perpendicular to the central axis of the first air outlet hole on the first gas pipeline.

[0020] In this way, the gas in the second gas pipeline can sequentially enter the second burner through the second air outlet hole, the air inlet hole of the automatic control valve, and the air outlet hole. The automatic control valve can be used to control the on-off of the gas flowing to the second burner.

[0021] In some embodiments of the present application, the mechanical valve may include: a valve body and a seal. Among them, an air inlet is provided on the valve body. The air inlet is communicated with the first air outlet hole on the first gas pipeline, and the seal is arranged between the valve body and the wall surface around the first air outlet hole.

[0022] In this way, the interface between the first air outlet hole and the air inlet on the valve body can be sealed, and it is not easy for gas to leak during the process of flowing from the first air outlet hole to the air inlet on the valve body.

[0023] In some embodiments of the present application, the diameter of the air inlet on the mechanical valve body may be 9 mm, and the diameter of the seal may be 13 mm; the first air outlet hole on the first gas pipeline may be a kidney-shaped hole, the aperture length of the first air outlet hole is 10 mm, and the width is 9 mm.

[0024] In this way, a 1-mm adjustment gap can be provided for the first air outlet hole to ensure its normal installation. At the same time, it is also ensured that the diameter of the sealing ring is larger than the aperture of the first air outlet hole, ensuring that gas does not leak during the process of flowing from the air inlet 241 to the air inlet on the mechanical valve body.

[0025] In some embodiments of the present application, both the first gas pipeline and the second gas pipeline are connected to the connecting member by welding.

[0026] In this way, the first gas pipeline, the connecting component, and the second gas pipeline can be tightly connected, and gas can flow from the first gas passage of the first gas pipeline to the gas chamber of the connecting component without leakage, and then from the gas chamber of the connecting component to the second gas passage of the second gas pipeline.

[0027] The present application also provides a gas stove, including: a first gas pipeline, a second gas pipeline, a connecting component, a mechanical valve, and an automatic control valve. Among them, the air inlet of the mechanical valve is connected to the first gas pipeline, and the air inlet hole of the automatic control valve is connected to the second gas pipeline; a gas chamber is provided in the connecting component, and the connecting component is connected between the first gas pipeline and the second gas pipeline, so that the gas in the first gas pipeline enters the second gas pipeline through the gas chamber.

[0028] In this way, the air inlet pipe can be connected to the mechanical valve and the automatic control valve without multiple bends. The single gas pipeline is connected through the connecting component. The manufacturing of the gas pipeline and the connecting component is simpler and more convenient than that of the air inlet pipe with multiple bends, and there will be no dimensional deviation caused by bending.

[0060] With the rapid development of technology, the demands of modern families for kitchen appliances are no longer limited to basic cooking functions, but rather place more emphasis on multi-faceted experiences such as high efficiency, convenience, safety, and health. As the core tool for cooking, intelligent cooking gas stoves have emerged. An intelligent cooking gas stove can, according to recipes and the personalized needs of users, real-time monitor the size of the cooking fire, the oil temperature, the cooking time, etc. during the cooking process, and thus automatically adjust the gas inlet and outlet to make the gas stove reach the optimal cooking state.

[0061] An intelligent cooking gas stove usually has two control methods: intelligent adjustment and manual adjustment. Intelligent adjustment is achieved by an automatic control valve body controlling the gas intake volume and intake time; while manual adjustment controls the gas intake volume and intake time through a traditional mechanical control valve body. Therefore, the intake pipe of an intelligent cooking gas stove has different intake ports: the intake port of the automatic control valve body and the intake port of the mechanical control valve body.

[0062] In the prior art, most of the intake ports of the automatic control valve body are at the rear side of the valve body, and most of the intake ports of the mechanical control valve body are at the upper side of the valve body. That is to say, the plane of the intake port of the automatic control valve body of the intake pipe is perpendicular to the horizontal plane, and the plane of the intake port of the mechanical control valve body is parallel to the horizontal plane, and the planes where they are located are different; at the same time, the heights of the automatic control valve and the mechanical control valve are different, resulting in different heights of the intake ports.

[0063] For most intelligent cooking gas stoves, the intake pipe is processed by bending, which increases the manufacturing difficulty of the intake pipe. At the same time, multiple bends increase the accumulation of dimensional errors, resulting in a relatively large final dimensional deviation, and the intake pipe cannot be normally assembled.

[0064] Based on this, an embodiment of the present application provides a gas stove. By splitting the intake pipe into a first gas delivery pipe, a second gas delivery pipe, and a connecting member, the first gas delivery pipe is connected to a mechanical valve, the second gas delivery pipe is connected [to something not specified in the original], and the connecting member is connected between the first gas delivery pipe and the second gas delivery pipe, enabling the gas in the first gas delivery pipe to enter the second gas delivery pipe through the connecting member. In this way, the first gas delivery pipe and the second gas delivery pipe can be at different heights, and the intake port can be in different directions, thereby solving the problems of manufacturing difficulties and abnormal assembly caused by bending the intake pipe during processing.

[0065] Please refer to Figure 1 , an embodiment of the present application provides a gas stove Figure 1 which is a schematic structural diagram of a gas stove 100 provided by an embodiment of the present application. The gas stove 100 includes: a burner 10 and an intake pipe assembly 20.

[0066] Among them, the burner 10 may include an ejector pipe, a burner head, a distributor, and a burner cap. The ejector pipe is connected to the valve body of the gas stove 100 and the external air, and is used to introduce gas and air into the burner head; a premixing chamber is provided in the burner head for mixing gas and air to obtain a mixed gas; the distributor is connected to the premixing chamber of the burner head for further mixing the mixed gas. The burner cap is covered on the distributor, so that the mixed gas in the premixing chamber is dispersed to each area of the burner cap, enabling the gas to burn evenly.

[0067] In order to facilitate users to cook multiple dishes simultaneously when using the gas stove 100 and improve cooking efficiency, in some embodiments, the burner 10 may be provided in multiple numbers. Exemplarily, the burner may include: a first burner 11 and a second burner 12.

[0068] The intake pipe assembly 20 may include a first gas delivery pipe 21, a second gas delivery pipe 22, a connecting member 23, a mechanical valve 24, and an automatic control valve 25.

[0069] Among them, the intake pipe assembly 20 is connected to the burner 10 and is used to deliver gas to the burner 10. Among them, the mechanical valve 24 is connected to the first burner 11, and the automatic control valve 25 is connected to the second burner 12.

[0070] Please refer to Figure 2 , Figure 2 which is a schematic structural diagram of an intake pipe assembly 20 provided by an embodiment of the present application. The mechanical valve 24 is connected to the first gas delivery pipe 21 and is used to control whether the gas in the first gas delivery pipe 21 enters the first burner 11. The automatic control valve 25 is connected to the second gas delivery pipe 22 and is used to control whether the gas in the second gas delivery pipe 22 enters the second burner 12.

[0071] In addition, please refer to Figure 3 , Figure 3Schematic diagram of a connection component 23 provided by an embodiment of the present application. An air delivery chamber 233 is provided on the connection component 23, and it is connected between a first air delivery pipe 21 and a second air delivery pipe 22, and is used to connect the first air delivery pipe 21 and the second air delivery pipe 22, so that the gas in the first air delivery pipe 21 can be delivered into the second air delivery pipe 22 through the air delivery chamber 233.

[0072] It can be understood that two mechanical valves 24 can be provided. The mechanical valve 24 can include: a first mechanical valve 24A and a second mechanical valve 24B. The first mechanical valve 24A and the second mechanical valve 24B can be connected to different positions of the first air delivery pipe 21.

[0073] In addition, the burner can further include: a third burner 13. The first mechanical valve 24A is connected to the first burner 11, that is, the first mechanical valve 24A can control whether the gas in the first air delivery pipe 21 enters the first burner 11. The second mechanical valve 24B is connected to the third burner 13, that is, the second mechanical valve 24B can control whether the gas in the first air delivery pipe 21 enters the third burner 13.

[0074] Since the connection component 23 is connected between the first air delivery pipe 21 and the second air delivery pipe 22, thus, if the heights of the first air delivery pipe 21 and the second air delivery pipe 22 are different, they can be connected in a staggered manner on the connection component 23. Compared with the prior art, there is no need to process the intake pipe by bending. Thereby reducing the manufacturing difficulty and ensuring the assembly accuracy of the intake pipe assembly 20.

[0075] Please refer to Figure 4 and Figure 5 , Figure 4 Schematic diagram of a main body of an intake pipe provided by an embodiment of the present application, Figure 5 Schematic diagram of a partial structure of a first air delivery pipe 21 provided by an embodiment of the present application.

The first air holes 231 communicate with the first gas pipeline 21, and the second air holes 232 communicate with the second gas pipeline 22.

[0082] In some embodiments, the heights of the first air holes 231 and the second air holes 232 may be different. In this way, the first gas pipeline 21 and the second gas pipeline 22 can be connected at different heights. In other embodiments, the heights of the first air holes 231 and the second air holes 232 may also be different, and the present application does not limit this.
