Description

Technical Field

[0001] The utility model relates to the field of stoves, in particular to a direct-insert valve structure for a double-burner stove and the double-burner stove. Background Art

[0002] In the prior art, double-burner stoves are more common among gas stoves, and they have two independent burners. This gas stove design can cook two different dishes at the same time, and each burner can independently control the firepower and temperature. In the home kitchen, double-burner stoves provide flexibility and efficiency, making the cooking process more convenient. However, the burner of each burner of the existing double-burner stove needs to be equipped with an independent plug-in valve. The two plug-in valves are first installed on the air intake pipe. Due to the existence of the tolerance dimension chain, in order to facilitate installation, the plug-in valve and the burner adopt the following clearance fit (single-side clearance of about 2mm), which will cause problems such as high smoke due to eccentric injection, low efficiency, more complicated assembly, and higher cost. Utility Model Content

[0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art in that the eccentric injection of double-eye stoves causes high smoke and low efficiency, while the assembly is more complicated and the cost is also higher. A direct-insert valve structure for a double-eye stove and a double-eye stove are provided.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] A direct-insert valve structure for a double-burner stove, comprising a left valve, a middle valve and a right valve;

[0006] The left valve and the right valve are respectively located on opposite sides of the middle valve facing the two burners of the double-burner stove;

[0007] An air inlet hole is provided on the middle valve, and the middle valve is directly connected to the left valve and the right valve.

[0008] In this solution, the aforementioned structure is employed, with the in-line valve divided into three parts: the left valve, the middle valve, and the right valve. Air enters the left and right valves directly from the middle valve, simplifying the air flow path and minimizing pressure loss. Furthermore, eliminating the need for two in-line valves reduces assembly tolerances, facilitating assembly, and avoiding the issues of high smoke levels and low efficiency caused by eccentric injection due to clearance fit, while also reducing costs.

[0009] Preferably, the intermediate valve includes a strip-shaped valve cavity, and two ends of the strip-shaped valve cavity are respectively connected to the left valve and the right valve.

[0010] In this solution, the above-mentioned structural form is adopted, and the middle valve has a strip valve cavity, which connects the left valve and the right valve. The middle part is used for air intake, and there is no need to set up an air intake pipeline. The structure is more compact and the cost is lower.

[0011] Preferably, the bottom of the middle valve is connected to the bottom plate of the double-burner stove, the air inlet is connected from the bottom of the double-burner stove to the strip valve cavity of the middle valve, and the left valve and the right valve are connected to the top of the middle valve.

[0012] In this solution, the above-mentioned structural form is adopted, and the plug-in valve structure adopts a stacked structure. The middle valve is located at the bottom and connected to the bottom plate so that the left valve and the right valve are connected to the middle valve from the top so that they partially overlap and stagger, reducing the lateral area and making the structure more compact.

[0013] Preferably, the left valve, the right valve and the middle valve are integrally formed.

[0014] In this solution, the above-mentioned structural form is adopted, and the plug-in valve structure is an integrated aluminum part. There is no tolerance deviation in the installation of the conventional plug-in valve, and the burner performance is good.

[0015] Preferably, the left valve includes a left air outlet pipe, and the left air outlet pipe is directly connected to the left ejector pipe of the left burner of the double-burner stove;

[0016] The right valve comprises a right air outlet pipe, and the right air outlet pipe is directly connected to the right ejector pipe of the right burner of the double-burner stove.

[0017] In this solution, the above-mentioned structural form is adopted, and the left valve and the right valve are respectively directly connected to the left ejection pipe and the right ejection pipe through the left outlet pipe and the right outlet pipe, eliminating the air intake pipe and realizing the use of a direct plug valve to simultaneously connect to two burners.

[0018] Preferably, the left valve further comprises a left solenoid valve, and the extension direction of the left solenoid valve is parallel to the extension direction of the left air outlet pipe;

[0019] The right valve further includes a right solenoid valve, and an extending direction of the right solenoid valve is perpendicular to an extending direction of the right air outlet pipe.

[0020] In this solution, the above-mentioned structural form is adopted, and the valve cavity of the left solenoid valve on the left side is perpendicular to the left air outlet pipe; the valve cavity of the right solenoid valve on the right side is parallel and opposite to the right air outlet pipe, so that the two solenoid valve cavities can be as close as possible in the whole machine state, thereby achieving consistency in the air intake of the left and right valves.

[0021] A double-burner stove comprises two burners and also comprises the above-mentioned in-line valve structure for the double-burner stove.

[0022] In this solution, the double-burner stove utilizes the aforementioned structure. The in-line valve is divided into three parts: the left valve, the middle valve, and the right valve. Air enters the left and right valves directly from the middle valve, simplifying the air intake path and minimizing pressure loss. Furthermore, eliminating the need for two in-line valves reduces assembly tolerances, facilitating assembly, and avoiding the issues of high smoke and low efficiency caused by eccentric ejection due to the need for clearance fit. This also reduces costs.

[0023] Preferably, the plug-in valve structure for the double-burner stove is arranged in the middle of the double-burner stove near the edge, and the ejector pipe of the burner extends toward the plug-in valve structure in an inclined shape.

[0024] In this solution, the above-mentioned structural form is adopted, and the layout of the two burners and the plug-in valve structure inside the double-burner stove is more reasonable and compact.

[0025] Preferably, positioning columns extending toward the plug-in valve are provided on both sides of the burner's ejector pipe, and a nozzle and a fixing plate are also provided on the outlet pipe of the plug-in valve. The fixing plate is fixed to the positioning columns and limits the nozzle.

[0026] In this solution, the above-mentioned structural form is adopted. The nozzle of the conventional plug-in valve requires a burner limiter, so the outlet of the ejector tube is not a fully open structure, and a paddle type with a slightly poor ejection effect is adopted. The plug-in valve structure of this solution ensures the concentricity of the plug-in valve system, so a high ejection system of the plug-in valve can be realized on its basis. The annular damper adjustment method is adopted, and the connection between the ejector tube and the outlet pipe of the plug-in valve is completed by the fixing column and the fixing plate. There is no need to set a crossbeam for fixing in the middle of the ejector tube, so that it can be set to a fully open structure, which has a better combustion effect.

[0027] Preferably, the nozzle is connected to the air outlet pipe via a thread, an outwardly protruding limiting ring is provided at the end of the air outlet pipe, and the nozzle and the fixing plate respectively abut against opposite sides of the limiting ring.

[0028] In this solution, the above-mentioned structural form is adopted, and the nozzle is double-limited by the thread and the fixing plate, which has good limiting and installation effects. The fixing plate and the straight-insert valve outlet pipe are installed concentrically. The overall structure is simple and the cost is relatively low.

[0029] The positive progress of the present invention lies in providing a direct-insert valve structure and a double-burner stove. The direct-insert valve is divided into three parts: the left valve, the middle valve, and the right valve. Intake air directly enters the left and right valves from the middle valve, simplifying the intake route and reducing pressure loss. Furthermore, the need for two direct-insert valves reduces assembly tolerances, making assembly easier. This also avoids the problem of high smoke and low efficiency caused by eccentric injection due to the need for clearance fit, while also reducing costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0059] like Figure 1 As shown, this embodiment discloses a double-burner stove, which includes two burners 2 and the above-mentioned plug-in valve structure 1 for the double-burner stove. The two burners 2 are respectively arranged on the left and right sides of the double-burner stove, and the plug-in valve structure 1 is arranged in the middle of the double-burner stove near the edge. The injection pipe 201 of the burner 2 extends toward the plug-in valve structure 1 in an inclined shape. The plug-in valve of the double-burner stove is divided into three parts: left, middle and right, namely the left valve 20, the middle valve 10 and the right valve 30. The intake air directly enters the left valve 20 and the right valve 30 from the middle valve 10. The intake route is simple and the pressure loss is small. At the same time, there is no need to set up two plug-in valves, which reduces the assembly tolerance, making assembly easier, and avoiding the problem of high smoke and low efficiency caused by the eccentric injection caused by the need for clearance fit, while also reducing costs. The layout of the two burners 2 and the plug-in valve structure 1 inside the double-burner stove is more reasonable and compact.

[0060] like Figures 2 to 6 As shown, the plug-in valve structure 1 for a double-burner stove of this embodiment includes a left valve 20, a middle valve 10, and a right valve 30. The left valve 20 and the right valve 30 are located on opposite sides of the middle valve 10 facing the two burners 2 of the double-burner stove. An air inlet 11 is provided on the middle valve 10, which directly connects to the left valve 20 and the right valve 30. The plug-in valve is divided into three parts: the left valve 20, the middle valve 10, and the right valve 30. The air intake directly enters the left valve 20 and the right valve 30 from the middle valve 10, simplifying the air intake route and reducing pressure loss. At the same time, there is no need to set up two plug-in valves, which reduces assembly tolerances, making assembly easier, avoiding the problem of high smoke and low efficiency caused by eccentric injection due to the need for clearance fit, and reducing costs.

[0061] like Figures 2 to 5 As shown, the intermediate valve 10 includes a strip valve cavity 12, which is a runway-shaped structure. Figure 5As shown, the two ends of the strip-shaped valve chamber 12 connect to the left valve 20 and the right valve 30, respectively. Circular through-holes are provided at the top of each longitudinal end of the strip-shaped valve chamber 12, each leading to the left valve 20 and the right valve 30. An air inlet hole 11 is provided at the center bottom for air intake. An air inlet solenoid valve is located in the position of air inlet hole 11. The middle valve 10 contains a strip-shaped valve chamber 12, which connects the left valve 20 and the right valve 30. The center portion is used for air intake, eliminating the need for air intake piping, resulting in a more compact structure and lower costs.

[0062] like Figure 5 As shown, the bottom of the intermediate valve 10 is connected to the bottom plate of the double-burner stove. The air inlet 11 leads from the bottom of the double-burner stove to the strip-shaped valve cavity 12 of the intermediate valve 10. The left valve 20 and the right valve 30 are connected to the top of the intermediate valve 10. Specifically, the intermediate valve 10 is provided with outwardly extending edges on all sides, each of which is provided with a bottom plate mounting hole 13 and a valve mounting hole 14. The bottom plate mounting holes 13 are located on both sides of the long side of the intermediate valve 10, and the valve mounting holes 14 are located on both sides of its length.

[0063] The plug-in valve structure 1 adopts a stacked structure, with the middle valve 10 located at the bottom and connected to the bottom plate so that the left valve 20 and the right valve 30 are connected to the middle valve 10 from the top so that they partially overlap and stagger, reducing the lateral area and making the structure more compact.

[0064] In this embodiment, the left valve 20, the right valve 30 and the middle valve 10 are integrally formed. The plug-in valve structure 1 is an integral aluminum part, which does not have the tolerance deviation of conventional plug-in valve assembly, and the burner 2 has good performance.

[0065] like Figure 1 As shown, the left valve 20 includes a left air outlet pipe, which is directly connected to the left injection pipe 201 of the left burner 2 of the double-burner stove. The right valve 30 includes a right air outlet pipe, which is directly connected to the right injection pipe 201 of the right burner 2 of the double-burner stove.

[0066] The left valve 20 and the right valve 30 are directly connected to the left ejection pipe 201 and the right ejection pipe 201 respectively through the left outlet pipe and the right outlet pipe, eliminating the air intake pipeline and realizing the direct connection with two burners 2 at the same time using one direct plug valve.

[0067] like Figure 4 As shown, the left valve 20 also includes a left solenoid valve 22, which extends parallel to the left outlet pipe. The right valve 30 also includes a right solenoid valve 32, which extends perpendicular to the right outlet pipe. The valve cavity of the left solenoid valve 22 on the left side is perpendicular to the left outlet pipe; the valve cavity of the right solenoid valve 32 on the right side is parallel to the right outlet pipe and in opposite directions. This ensures that the two solenoid valve cavities are as close as possible when the device is in its entirety, thereby ensuring consistent air intake between the left and right valves 30.

[0068] like Figure 6 、 Figure 7 As shown, positioning columns 202 extending toward the plug-in valve are provided on both sides of the ejector tube 201 of the burner 2. A nozzle 101 and a fixing plate 203 are also provided on the outlet pipe of the plug-in valve. The fixing plate 203 is fixed to the positioning columns 202 and limits the nozzle 101.

[0069] The nozzle 101 of the conventional plug-in valve requires the burner 2 to limit the position, so the outlet of the ejector tube 201 is not a fully open structure, and the paddle type with a slightly poor ejection effect is adopted. The plug-in valve structure 1 of this solution ensures the concentricity of the plug-in valve system, so the high ejection system of the plug-in valve can be realized on its basis. The annular damper adjustment method is adopted, and the ejector tube 201 is connected to the outlet pipe of the plug-in valve through the fixing column and the fixing plate 203. There is no need to set a crossbeam for fixing in the middle of the ejector tube 201, so that it can be set to a fully open structure, such as Figure 8 As shown, the combustion effect is better.

[0070] like Figure 9 As shown, the nozzle 101 is connected to the outlet pipe via threads. The end of the outlet pipe is provided with an outwardly protruding retaining ring 102. The nozzle 101 and the fixing plate 203 respectively abut against opposite sides of the retaining ring 102. The threads and the fixing plate 203 provide a double limit for the nozzle 101, providing effective positioning and installation. The fixing plate 203 is installed concentrically with the outlet pipe of the in-line valve, resulting in a simple overall structure and relatively low cost.

[0071] Although specific embodiments of the present invention have been described above, those skilled in the art will appreciate that these are merely illustrative and that the scope of protection of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and such changes and modifications are intended to fall within the scope of protection of the present invention.
