Description

Technical Field

[0001] The utility model belongs to the technical field of water heaters, in particular to a combustion chamber of a water heater. Background Art

[0002] A gas water heater, also known as a gas water boiler, is a gas appliance that uses gas as fuel, heats the gas through a burner to a heat exchanger, and then converts it into flowing water through a heat exchanger to make hot water. The fan then draws the exhaust gas generated by the combustion to the outdoors. The valve body assembly controls the entire working procedure of the water heater, which includes a water valve, a gas valve, a micro switch, an igniter, etc.

[0003] The forced exhaust water heaters currently on the market have the following problems when used:

[0004] 1. The traditional forced-exhaust water heater has a heat exchanger and a combustion chamber as one body, and the combustion chamber is surrounded by a coil for cooling. At present, the value of manufactured products is depreciating, and the price of raw materials, especially copper materials, is rising. However, in order to gain a foothold in the market, traditional forced-exhaust water heaters have to reduce the weight of the copper material of the water tank to reduce costs. However, once the material becomes thinner, it is easy to cause the water tank to deform, or even burn through and leak, which seriously affects the life of the whole machine.

[0005] 2. The traditional forced exhaust water heater has a notch on the front of the water tank, which is easy to see the fire and install the ignition needle, but it is easy to cause the flame to leak out. In addition, the fire exhaust is open for combustion, so a large part of the heat leaks out, making the internal temperature of the water heater too high, so that other parts are easily burned, which shortens its lifespan during use;

[0006] 3. The deformation of the water tank affects the flame combustion. The open fire grate combustion cannot control the air intake. These are not good for the control of smoke, causing carbon monoxide to exceed the standard, so it is difficult to produce; the noise is loud during combustion and there is no sound insulation. This way the combustion is not only insufficient and unstable, which indirectly leads to high production costs, but also the whole machine is not safe enough when used. Utility Model Content

[0007] The utility model aims to provide a water heater combustion chamber to solve the technical problems raised in the background technology.

[0008] To achieve the above-mentioned purpose, the specific technical scheme of the utility model is as follows: it includes a back plate and a panel, a first heat insulation plate, a second heat insulation plate, an air intake baffle, and a mounting bracket.

[0016] 2. The combustion chamber of the water heater is provided with a back plate, a panel, a first side plate, a second side plate, a baffle and other structures, so that the combustion is more complete. The back plate, the panel, the first side plate, the second side plate and the baffle are assembled in a closed environment on all sides, so that the fire inside the burner can burn in the sealed space, and the flame and heat are prevented from leaking out. The baffle at the bottom accurately controls the air to enter, so that the combustion is complete and it is safer when in use.

The combustion chamber of the water heater is provided with a first heat insulation board, a second heat insulation board, a third heat insulation board, a fourth heat insulation board, a first perforation, a second perforation and other structures inside the shell, so that an annular space can be formed. The heat insulation board is installed inside the shell by fasteners, so that it can effectively soundproof and heat-insulate during combustion. Then, the heat in the heat insulation board and part of the air enter the combustion chamber through the first and second perforations, so that the combustion is more complete and the heat utilization value is higher during application.
