Detailed Description

The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

As shown in fig. 2 to 5, it is a gas water heater, which includes a heat exchanger 1, a preheating pipe 2 surrounding the heat exchanger, and a burner 3; the heat exchanger 1 is externally coated with a heat insulation and noise reduction layer 4, the burner 3 is externally coated with a heat insulation layer 5, and the preheating pipe 2 is positioned between the heat exchanger 1 and the heat insulation and noise reduction layer 3. When the heat-insulating and noise-reducing layer 4 is used, the heat-insulating and noise-reducing layer can be used for preserving and insulating heat of the heat exchanger 1, so that the surface temperature of the heat exchanger 1 is reduced, the noise generated when the heat exchanger 1 works is also reduced, meanwhile, the preheating pipe 2 can better absorb the surface temperature of the heat exchanger 1, and the heat efficiency is improved; the heat insulating layer 5 can insulate heat and reduce noise of the combustor, and the service life of the surface cover and the electric control board is more effectively protected.

In this embodiment, the heat insulation and noise reduction layer 3 is composed of three layers of materials, namely an inner layer 43, a middle layer 42 and an outer layer 41, wherein the inner layer 43 is an aluminum foil, the middle layer 42 is heat insulation rubber-plastic cotton, and the outer layer 41 is wave cotton.

In this embodiment, the thermal insulation layer 5 is formed by combining two layers of materials, namely an inner layer 52 and an outer layer 51, wherein the inner layer 52 is an aluminum foil, and the outer layer 51 is high-density thermal insulation rubber-plastic cotton.

In this embodiment, a layer of aluminum foil 6 is wrapped at the junction of the heat exchanger 1 and the burner 3.

The embodiments of the present invention are described in detail above with reference to the drawings, but the present invention is not limited to the described embodiments.
