Abstract

The invention discloses a gas water heater. The gas water heater comprises a pre-mixing cavity shell, a combustor, a heat exchanger, a pre-heating disc and controller; a mixing cavity is limited in the pre-mixing cavity shell, and the pre-mixing cavity shell is provided with a gas inlet, an air inlet and a mixed gas outlet which are communicated with the mixing cavity; the combustor is communicated with the mixed gas outlet, and a catalyst for catalyzing the combustor to carry out smokeless catalytic combustion is arranged in the combustor; the heat exchanger is connected with the combustor so as to absorb heat generated by combusting of the combustor and is provided with a water inlet and a water outlet; the pre-heating disc is connected with the combustor so as to preheat the combustor; and the controller is connected with the pre-heating disc so as to control heating temperature of the pre-heating disc. According to the gas water heater, the reaction rate of fuel can be improved, the utilization rate of the fuel is improved, generation of harmful gas can be avoided, the fuel can be subject to flameless catalytic combustion in the combustor, generation of the harmful gas is greatly reduced, and use is safe and environment-friendly.

Description

technical field

[0001] The present invention relates to the technical field of water heaters, in particular to a gas water heater. Background technique

[0002] The main combustion method used by the burner of the gas water heater in the related art is flaming combustion, which not only reduces the energy utilization rate, but also emits a large amount of pollutants during the combustion process, which is one of the main reasons for the frequent occurrence of smog weather. . Therefore, it is considered to be the most ideal combustion method to replace the traditional low-efficiency combustion method with an efficient and clean combustion method. Contents of the invention

[0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the present invention proposes a gas water heater, which has a simple structure, reliable connection of components, convenient assembly and disassembly, flameless catalyt...
