Abstract
Description
Technical Field
[0001] The utility model relates to an air inlet pipe structure of an air distribution plate.
Background Art
[0002] At present, there is a sheet metal air distribution plate in the market. The bottom shell, burner cap and other components of the air distribution plate are all formed by sheet metal stamping, and are fixed to each other by riveting. An air inlet pipe is provided on the bottom of the air distribution plate to facilitate connection with the stove head to guide the gas transmission. At present, the air inlet pipe is formed by stretching during the production of the bottom shell, that is, the air inlet pipe and the bottom shell are an integral structure. However, this structure has the disadvantage that the length of the air inlet pipe is short, and there are certain differences in the length of each stretching of the air inlet pipe. Coupled with the subsequent need for cutting, grinding and other processes, the length of the air inlet pipe is even more difficult to control.
[0003] Therefore, it is necessary to make further improvements to it.
Content of the Utility Model
[0004] The purpose of the utility model is to overcome the above problems. We provide an air inlet pipe structure of an air distribution plate. Using this air inlet pipe structure can solve the problem of non-uniform length of the air inlet pipe.
[0005] To achieve the above purpose, the utility model provides an air inlet pipe structure of an air distribution plate, which includes an air distribution plate main body and an air inlet pipe. An air inlet is provided at the center of the bottom of the air distribution plate main body. The upper end of the air inlet pipe abuts against the bottom of the air distribution plate main body, and the air inlet pipe has a first annular riveting wall passing through the air inlet. The upper end of the first annular riveting wall bends outward and is riveted and fixed to the bottom of the air distribution plate main body.
[0006] In one or more embodiments, the outer diameter of the first annular riveting wall is the same as the diameter of the air inlet.
[0007] In one or more embodiments, a central air port is provided at the center of the top of the air distribution plate main body. A central air pipe is connected to the central air port. The upper end of the central air pipe abuts against the inner top of the air distribution plate main body, and the central air pipe has a second annular riveting wall passing through the central air port. The upper end of the second annular riveting wall bends outward and is riveted and fixed to the outer wall of the air distribution plate main body.
[0008] In one or more embodiments, the outer diameter of the second annular riveting wall is the same as the diameter of the central air port.
[0009] In one or more embodiments, both the central air pipe and the air inlet pipe are straight pipe structures with upper and lower openings.
[0010] In one or more embodiments, the air distribution plate main body, the air inlet pipe and the central air pipe are all made of sheet metal materials.
[0011] The effects of the present utility model compared with the background technology are as follows: The intake pipe and the main body of the air distribution plate are installed and fixed by riveting. The length dimension of the intake pipe can be unified by cutting production with a unified length, and the length of the intake pipe is controllable, ensuring the uniformity of the intake pipe specifications of the air distribution plate. In addition, after the length of the intake pipe is controllable, when it is connected to the burner head, the distance between the air distribution plate and the burner head can be controlled by controlling the length of the intake pipe, thereby reducing the heat conduction of the air distribution plate to the burner head.

Detailed Embodiment
[0014] This part will describe the specific embodiments of the present utility model in detail. The preferred embodiments of the present utility model are shown in the drawings. The role of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.
[0015] Refer to the attached Figure 1-2 , this application provides an intake pipe structure of an air distribution plate, which includes a main body 1 of the air distribution plate and an intake pipe 2. An air inlet 3 is provided at the center of the bottom of the main body of the air distribution plate. The upper end of the intake pipe 2 abuts against the bottom of the main body 1 of the air distribution plate, and the intake pipe 2 has a first annular riveting wall 4 passing through the air inlet 3. The upper end of the first annular riveting wall bends outward and is riveted and fixed to the bottom of the main body 1 of the air distribution plate. The intake pipe can be machined by a machine tool to cut off a part of the outer circumference of its top to form the first annular riveting wall. By adopting the above intake pipe installation structure in this application, the length of the intake pipe can be unified, the regularity of the produced air distribution plates can be unified, and the length of the intake pipe can be controlled as needed. After the air distribution plate and the burner head are assembled, the distance between the air distribution plate and the burner head can be controlled, and the length of the intake pipe can be controlled to extend the distance of heat transfer, avoiding the burner head from overheating.
[0016] The outer diameter of the first annular riveting wall 4 is the same as the diameter of the air inlet 3, making the connection between the first annular riveting wall and the air inlet closer, and making the structure of the intake pipe and the main body of the air distribution plate more stable after riveting.
[0017] At the center of the top of the main body 1 of the gas distribution plate, there is a central gas port 5. A central gas pipe 6 is connected to the upper part of the central gas port. The central gas pipe is used to supply gas to the central burner cap on the main body of the gas distribution plate. The upper end of the central gas pipe abuts against the inner top of the main body 1 of the gas distribution plate. And the central gas pipe 6 has a second annular riveting wall 7 passing through the central gas port. The upper end of the second annular riveting wall bends outward and is riveted and fixed to the outer wall of the main body 1 of the gas distribution plate. The installation and fixing method of the central gas pipe is the same as that of the intake pipe, and will not be repeated here.
[0018] The outer diameter of the second annular riveting wall 7 is the same as the diameter of the central gas port 5, making the connection between the second annular riveting wall and the central gas port closer. After riveting, the structure of the central gas pipe and the main body of the gas distribution plate is more stable.
[0019] Preferably, both the central gas pipe 6 and the intake pipe 2 are straight pipe structures with openings at both the upper and lower ends. The main body 1 of the gas distribution plate, the intake pipe 2 and the central gas pipe 6 are all made of sheet metal materials.
[0020] Of course, the present invention is not limited to the above embodiments. Those skilled in the art can make equivalent deformations or replacements without departing from the spirit of the present invention. These equivalent deformations and replacements are all included in the scope defined by the claims of this application.
