Description

Technical Field

[0001] This utility model belongs to the technical field of gas water heaters, specifically a heat preservation shell device for gas water heaters. Background Technology

[0002] A gas water heater is a gas appliance that uses gas as fuel and heats water by transferring heat to cold water flowing through a heat exchanger. It mainly consists of a valve assembly, main burner, pilot burner, heat exchanger, and safety devices. It also includes the flue of a flue-type water heater and the forced draft device of a forced draft water heater. The basic working principle of a gas water heater is that cold water enters the water heater and flows through the water-gas linkage valve. Under the action of a certain pressure difference of the flowing water, the water-gas linkage valve is pushed, and at the same time, the DC power micro switch is activated to connect the power supply and start the pulse igniter.

[0003] To ensure the heat preservation effect of gas water heaters, an insulation shell is usually installed on the outside of the gas water heater for insulation. However, in the current technology, the insulation shell is usually installed on the outside of the gas water heater by multiple bolts, which makes the operation more cumbersome.
