Description

Technical Field

[0001] The utility model relates to a heat insulation structure of a gas water heater. Background Art

[0002] Gas water heaters are the most popular and longest-used water heaters on the market. Gas water heaters heat water by burning gas, so a combustion chamber is set up inside. The combustion chamber will generate high temperature when working, and it will be transmitted to the outside through the shell, causing the temperature inside the gas water heater to rise, affecting electrical components such as circuit boards. In addition, it will cause heat radiation to the outer shell of the gas water heater, causing it to heat up. If the user accidentally touches it, there is a risk of burns.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] The utility model aims to overcome the above problems and provide a heat insulation structure for a gas water heater, which can reduce the heat transfer from the combustion chamber to the outside.

[0005] To achieve the above-mentioned purpose, the utility model provides a gas water heater insulation structure, which includes a water heater shell and a combustion chamber arranged inside the water heater shell, the combustion chamber includes a shell, a combustion fire grate and an inner bracket, the shell is fixed to the water heater shell by a first screw, the inner bracket includes a fixing plate and a mounting plate of an integral structure, the fixing plate is connected and fixed to the shell, the mounting plate is suspended inside the shell, and the mounting plate is used to fix the combustion fire grate.

[0006] In one or more embodiments, the mounting plate is provided with a plurality of fixed bayonet sockets arranged side by side, the combustion fire bar comprises a plurality of fire bar pieces arranged side by side, and each fixed bayonet socket fixes a fire bar piece.

[0007] In one or more embodiments, the mounting plate has a plurality of folding structures, and the folding structures are arranged to extend horizontally.

[0008] In one or more embodiments, a plurality of through holes are formed on the folding structure.

[0009] In one or more embodiments, a supporting edge is provided on the top of the shell, the fixing plate is placed on the supporting edge and fits with the supporting edge, and the fixing plate is fixed to the supporting edge by a second screw.

[0010] In one or more embodiments, a plurality of positioning parts are provided on the fixing plate, and a socket for the positioning parts to be plugged into is opened on the supporting edge.

[0011] In one or more embodiments, a mounting frame is provided at the bottom of the shell, and the mounting frame has a plurality of connecting ears, and the connecting ears are fixed to the water heater shell by first screws.

[0012] Compared with the background technology, the utility model has the following effects: by setting an inner bracket to install the combustion fire grate, the heat transfer distance is extended and the direct contact area between the combustion fire grate and the shell is reduced, thereby reducing the heat from the combustion fire grate to the shell. After the temperature of the shell is reduced, the heat radiated to the outside is also reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0016] Please see attached Figure 1-2 The utility model provides a gas water heater insulation structure, which includes a water heater shell 1 and a combustion chamber arranged inside the water heater shell, the combustion chamber includes a shell 2, a combustion grate and an inner bracket 3, the shell 2 is fixed to the water heater shell 1 by a first screw 4, specifically, a mounting bracket is provided at the bottom position of the shell 2, the mounting bracket has a plurality of connecting ears 12, the connecting ears are fixed to the water heater shell 1 by the first screw 4, and are connected to the water heater shell through the connecting ears, the contact area is reduced, and thus the heat transfer amount is also reduced, which can avoid heat transfer to the water heater shell, the inner bracket 3 includes a fixing plate 31 and a mounting plate 32 of an integral structure, the fixing plate 31 is connected and fixed to the shell 2, the mounting plate 32 is suspended inside the shell 2, the mounting plate is used to fix the combustion grate, because the mounting plate is arranged in a suspended manner and does not directly contact the shell, therefore, the heat of the combustion grate is not easily transferred to the shell.

[0017] The mounting plate 32 is provided with a plurality of fixed bayonet sockets 5 arranged side by side, and the combustion fire row includes a plurality of fire row pieces 6 arranged side by side. Each fixed bayonet fixes a fire row piece, and the position of each fire row piece is fixed by the fixed bayonet to ensure a certain interval between the fire row pieces.

[0018] The mounting plate 32 has a plurality of folding structures 7, which are arranged to extend horizontally. The folding structures can strengthen the structural strength of the mounting plate and make it have better bearing capacity. The folding structures are provided with a plurality of through holes 8, which play the role of ventilation and reducing the heat transfer area.
