Problems solved by technology

[0004] In the actual application process, on the one hand, there is a certain deviation in the gas proportional valve itself, which leads to the deviation of the firepower; When the flameout occurs, the combustion conditions will deteriorate, etc.
[0005] In the actual application process, if the gas pressure in the user's home is low, the output gas pressure (secondary pressure) of the proportional valve will also be lo

Abstract

The invention discloses a gas water heater with a wide adaption range and a control method thereof. The gas water heater comprises a combustion fire grate, a fire grate adjusting valve, a gas proportional valve, a main gas switching valve, a fan, a pressure sensor, a controller and a gas pipeline; a fire grate switching valve, the gas proportional valve and the main gas switching valve are arranged on the gas pipeline in sequence from top to bottom; the pressure sensor is arranged on the gas pipeline between the fire grate adjusting valve and the gas proportional valve; and the controller is electrically connected with control ends of the fire grate adjusting valve, the gas proportional valve, the main gas switching valve, the fan and the pressure sensor. The water heater can automatically correct deviation of the proportional valve, can sense and adjust the change condition of gas pressure, improves the adaptability, realizes automatic adjustment of ignition secondary pressure, low-load secondary pressure and high-load secondary pressure, and improves the production efficiency.

Description

technical field [0001] The invention belongs to the technical field of water heaters, and in particular relates to a gas water heater with a wide adaptability range and a control method thereof. Background technique [0002] Gas water heaters have become a necessity in family life. Especially the gas water heater with constant temperature function provides us with various hot water with constant temperature: before going to bed, we can take a hot bath comfortably to relieve fatigue; in cold winter, we will not let us use Wash vegetables with cold water; in the morning, let us wash comfortably with warm water; after meals, wash dishes with suitable hot water. [0003] However, the core component of the gas water heater to achieve constant temperature is the gas proportional valve. The controller of the water heater adjusts the amount of gas entering the combustion sheet by controlling the opening of the gas proportional valve, so as to realize the control of the firepower. ...
