Embodiment Construction

[0028] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] see figure 1 , figure 1 It is a structural schematic diagram of the first embodiment of the gas water heater of the present invention.

[0030] 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. The gas water heater comprises a heat exchanger with a water inlet pipe and a water outlet pipe and further comprises a descaling device arranged on the water inlet pipe; the descaling device is provided with a descaling agent cavity communicated with the water inlet pipe; a water way switch is arranged on a communication pipeline between the descaling agent cavity and the water inlet pipe. When the pipeline self-cleaning mode is switched on, a descaling agent in the descaling agent cavity flows into pipelines of the gas water heater along with water flow in the water inlet pipe, and accordingly water scale stuck to the inner walls of the pipelines can be cleaned. Therefore, the heat exchange efficiency of the gas water heater is improved, meanwhile the water quality is improved, and physically beneficial and safe bath water is guaranteed. Besides, the gas water heater can also achieve high temperature sterilization function on the pipelines, the cleanness of the pipelines is further improved, and the water healthy and safe to our body is guaranteed.

Description

[0001] This application is a divisional application of an invention patent application with an application date of August 29, 2013, an application number of 201310385205.1, and an invention titled "gas water heater". technical field [0002] 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 [0003] 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 se...
