Description

Technical Field

[0001] The utility model relates to the technical field of gas water heaters, in particular to a fixing structure of a base plate assembly of a gas water heater and a water heater body. Background Art

[0002] like Figure 1 As shown, the main base plate 1 of the existing gas water heater is generally fastened to the bottom plate 3 of the water heater body by respectively driving a screw 1 on both sides. In order to make the space inside the water heater compact, the main base plate 1 can only be installed laterally in the gap of the water heater, and the installation space is more restricted, which is inconvenient to operate during assembly. In order to block the high temperature from the heat exchanger, it is necessary to additionally weld a metal insulation baffle 4 on the bottom plate 3 of the water heater body; in addition, the metal insulation baffle 4 blocks the front side of the main base plate 1. When it is necessary to plug and unplug the plug-in parts on the main base plate 1 or perform other operations, the metal insulation baffle 4 needs to be disassembled and removed before the operation can be performed, which is very inconvenient.

[0003] Therefore, how to optimize the fixing structure of the main base plate of the gas water heater and improve the convenience of assembling the main base plate and the plug-in components thereon has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0004] In view of the above-mentioned defects of the prior art, the utility model provides a fixing structure of a gas water heater base plate assembly and a water heater body, the purpose of which is to improve the assembly convenience of the main base plate of the gas water heater and the plug-in on the main base plate.

[0005] To achieve the above technical purpose, the utility model provides a fixing structure of a gas water heater base plate assembly and a water heater body, comprising a main base plate, the main base plate is arranged in front of a fan in the gas water heater, and the front side of the main base plate is arranged outward;

[0006] One side of the main base plate is fixedly connected to the shell of the water heater body die-casting by a screw, and the other side is plugged and fixed in a positioning hole opened on the bottom plate of the water heater body by a positioning column.

[0007] Preferably, a locking structure is provided at the end of the positioning column inserted into the positioning hole, and the positioning hole is a waist-shaped hole.

[0008] Preferably, the locking structure is elastic, and when the locking structure is inserted into the positioning hole, the locking structure will be tightened in the positioning hole.

[0009] Beneficial effects of the utility model:

[0010] Due to the above-mentioned structural design, the utility model has a main base plate which is installed on the front side of the fan in the water heater with the front side facing outward only by using a positioning column and a screw, eliminating an additional metal heat insulation baffle, which not only improves the assembly convenience of the main base plate, but also improves the assembly convenience of the plug-in parts on the main base plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a structural schematic diagram of the prior art;

[0012] Figure 2 This is a schematic diagram of the structure of an embodiment of the utility model;

[0013] Figure 3 It is a structural schematic diagram of the locking structure and the positioning hole in one embodiment of the utility model.

[0014] In the figure: 1 main base plate, 2 screws, 3 water heater body bottom plate, 4 metal heat insulation baffle, 5 water heater body die casting, 6 positioning column, 7 clamping structure, 8 positioning hole. DETAILED DESCRIPTION

[0015] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention.

[0016] Example:

[0017] like Figure 2-Figure 3 As shown, the fixing structure of the gas water heater base plate assembly and the water heater body includes a main base plate 1, which is arranged in front of the fan in the gas water heater, and the front side of the main base plate 1 is arranged outward;

[0018] One side of the main base plate 1 is fixedly connected to the shell of the water heater body die casting 5 through a screw 2, and the other side is inserted and fixed in the positioning hole 8 opened on the bottom plate 3 of the water heater body through a positioning column 6.

[0019] The main innovation of the utility model is that the installation position of the main base plate 1 in the water heater is changed, and no additional insulation structure is required. At the same time, the installation and fastening method of the main base plate 1 is optimized and improved, thereby improving the assembly convenience of the main base plate 1 and the plug-in components.

[0020] The end of the positioning column 6 inserted into the positioning hole 8 is provided with a locking structure 7, and the positioning hole 8 is a waist-shaped hole.

[0021] The locking structure 7 is elastic. When the locking structure 7 is inserted into the positioning hole 8 , the locking structure 7 will be tightened in the positioning hole 8 .

[0022] In summary, compared with the prior art, the utility model installs the main substrate 1 on the front side of the fan inside the water heater. The front side of the fan belongs to the low-temperature area inside the water heater, so there is no need to add additional insulation structures such as metal insulation baffles 4; secondly, the front side of the main substrate 1 faces outward, that is, toward the operator, which greatly improves the convenience of plugging and unplugging connectors on the main substrate 1; in addition, the main substrate 1 only needs one screw 2 to achieve the fastening connection of the main substrate 1, which reduces the assembly time and material consumption, and improves the assembly reliability index of the product.

[0023] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
