Embodiment Construction

[0032] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. 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 present invention.

[0033] The main combustion method used by the burner of a gas water heater is flame combustion: the gas and air are not pre-mixed in the combustion device, but are sent to the combustion chamber separately, and burn while mixing in the combustion chamber. The flame produced by burning in this way is longer and has a sharp outline, which belongs to diffusion burning. Due to the high activation energy of flaming combustion, the combustion speed is slow and the combustion is incomplete, which will lead to a decrease in thermal efficiency. In addition, the gas radiation of the flaming combustion flame is small, and the main heat transfer method is convective heat tr...

Abstract

The invention discloses a gas water heater which comprises a shell, a premixing cavity shell, a burner, a heat exchanger, a preheating plate and a controller, wherein an accommodating cavity is defined inside the shell; the shell has an exhaust hole, a hot water outlet and a cold water inlet; the premixing cavity shell is arranged in the accommodating cavity; a mixing cavity is defined in the premixing cavity shell; the burner is arranged below the mixing cavity, and communicates with the mixing cavity; a catalyst for allowing smokeless catalytic combustion of a catalytic burner is arranged in the burner; the heat exchanger is arranged below the burner and is connected with the burner for absorbing heat generated from combustion of the burner; the heat exchanger has a water inlet and a water outlet; the water inlet communicates with the cold water inlet; the water outlet communicates with the hot water outlet; the preheating plate is connected with the burner for preheating the burner; and the controller is connected with the preheating plate for controlling the heating temperature of the preheating plate. According to the gas water heater provided by the embodiment of the invention, the generation of carbon monoxide and nitrogen oxide can be controlled from the source, and the utilization 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...
