Problems solved by technology

[0002] Gas water heaters in the related art will generate scale in the waterway part of the heat exchanger as the working time prolongs, seriously reducing the heat exchange efficiency, and excessive accumulation of scale will easily lead to Hidden danger of dry burning
For this reason, some water heaters are descaled by injecting a descaling agent into the heat exchanger, but frequent descaling operations are required, which is very troublesome

Embodiment Construction

[0019] The present invention is based on the inventors of the present application's discovery of the following facts and problems:

[0020] In the gas water heater in the related art, after the work is completed, there will be water in the heat exchanger. After the gas water heater stops working, the water will not move, and will be heated by the waste heat of the heat exchanger.

[0021] Therefore, the present invention proposes a gas water heater 1, which has the advantages of not easy to scale, good heat exchange effect, and long service life.

[0022] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the p...

Abstract

The invention discloses a gas water heater. The gas water heater comprises a heat exchanger, a combustor, a circulating pipeline and a circulating water pump. A water inlet port and a water outlet port are arranged in the heat exchanger. The combustor is used for heating the heat exchanger and a gas inlet port is arranged in the combustor. The circulating pipeline communicates with the water inlet port and the water outlet port separately. The circulating water pump is connected on the circulating pipeline. The gas water heater provided by the invention has the advantages of being not liable to scale formation, good in heat exchanging effect, long in service life and the like.

Description

technical field [0001] The invention relates to the technical field of electric appliance manufacturing, in particular to a gas water heater. Background technique [0002] In the gas water heater in the related art, as the working time prolongs, scale will be generated in the waterway part of the heat exchanger, which will seriously reduce the heat exchange efficiency, and excessive accumulation of scale will easily lead to hidden dangers of dry burning. For this reason, some water heaters are descaled by injecting a descaling agent into the heat exchanger, but frequent descaling operations are required, which is very troublesome. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the prior art at least to a certain extent. Therefore, the present invention proposes a gas water heater, which has the advantages of not easy to scale, good heat exchange effect, long service life and the like. [0004] In or...
