Embodiment Construction

[0027] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] see figure 1 , figure 1 It is a structural schematic diagram of the first embodiment of the gas water heater of the present invention.

[0029] The gas water heater provided in this embodiment includes a burner 12, an air inlet pipeline 13 for supplying combustible gas to the burner 12, a heat exchanger 10 with a water inlet pipe 14 and a water outlet pipe 15, and a heat exchanger 10 for the burner 12 and the water outlet pipe 15. The heat exchanger 10 discharges the exhaust gas through the flue pipe 11 . The burner 12 is used to heat the heat exchanger 10, and the heat exchanger 10 is used to perform heat exchange treatment on the water flow passing through the pipeline of the heat exchanger 10, thereby realizing heating of the water flow. During the long-term use of gas water heaters, because the water con...

Abstract

The invention discloses a gas water heater which comprises a heat exchanger and a descaling device. The heat exchanger is provided with a water inlet pipe and a water outlet pipe, the descaling device is arranged on the water inlet pipe and is provided with a descaling agent cavity, the descaling agent cavity is communicated with the water inlet pipe, and a waterway switch is arranged on a communication pipeline between the descaling agent cavity and the water inlet pipe. The gas water heater has the advantages that when a pipeline self-cleaning mode is started, descaling agents in the descaling agent cavity flow into pipelines of the gas water heater along with water flow in the water inlet pipe, so that the purpose of cleaning scale adhered on the inner walls of the pipelines can be achieved, the heat exchange efficiency of the gas water heater can be improved, the quality of water can be enhanced, and the healthfulness and the safety of the bathing water can be guaranteed; the gas water heater further has a high-temperature pipeline sterilization function, so that the cleanliness of the pipelines can be further improved, and the healthfulness and the safety of the bathing water can be further guaranteed.

Description

technical field [0001] The invention relates to the technical field of gas water heaters, in particular to a gas water heater with a pipeline cleaning device. Background technique [0002] Since daily water contains calcium and magnesium ions, calcium and magnesium ions are easy to combine with acid radical ions in the water to form insoluble substances when heated, and stick to the inner wall of the gas water heater pipeline to form scale, especially the heat exchanger. After the inner wall of the heat exchange tube is scaled, it will have a great impact on the heat exchange efficiency of the gas water heater. The accumulation of scale for a long time will also block the pipeline, and in severe cases, it may lead to the scrapping of the gas water heater or serious accidents. In addition, the scale bonded to the wall of the water heater can also breed bacteria and pollute the water quality, thereby affecting the health of users. Contents of the invention [0003] The mai...
