Gas water heater with uniform flame combustion

Abstract

The invention discloses a gas water heater with uniform flame combustion. The gas water heater comprises a shell, a uniform flame combustion system and a control system. The shell comprises a bottom shell and a surface shell, wherein the bottom shell and the surface shell are combined into a cuboid water heater outer frame structure. The gas water heater with uniform flame combustion can automatically adjust a combustion state according to environment and user requirements, the combustion state is adjusted to a full-open combustion state or a half-open combustion state through a gas distributor, uniform heating of a heat exchanger can be achieved under both the two different combustion states, heat efficiency in the half-open combustion state is improved, and the situation that due to a small heating area, a great quantity of heat is wasted due to the fact that the heat is not absorbed, namely a large quantity of gas energy is wasted is avoided. Meanwhile, local heating of the heat exchanger is avoided, and the service life of the heat exchanger is prolonged. Through a unique bidirectional fire transmission mode, during switching between large fire and small fire, the fire transmission success rate is increased, and the using and combustion processes are more convenient to control.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a gas water heater with uniform flame combustion. Background technique [0002] Gas water heater refers to a burning appliance that uses gas as fuel to transfer heat to cold water flowing through the exchanger through combustion and heating to achieve the purpose of preparing hot water; [0003] When the water flow rate is large and the water inlet temperature is low, the gas water heater generally makes all the burners ignite and burn. We call this state "full open combustion state". Under the circumstances, the gas water heater does not need to turn on all the burners, and only a part of the burners need to be ignited to meet the user's set temperature requirements. We call this state "half-open combustion state". In most cases, especially in summer, gas water heaters work in a half-burning state. [0004] However, when the traditional gas water heater works in the half...
