Problems solved by technology

[0003] Because the energy required for the operation of gas water heaters comes from gas, which is a flammable and explosive gas, the environment where gas water heaters are generally placed is relatively high humidity, and water vapor will cause corrosion and other effects on the components of the gas water heater, which are generally not available in existing gas water heaters. Humidity detection function

Abstract

The invention discloses a gas water heater for preventing moisture corrosion. A moisture-sensitive sensor module is mounted on the external part of the gas water heater, so that the change in humidity in the ambient environment can be detected in the use process of the gas water heater and the gas water heater can be effectively protected. The moisture-sensitive sensor module is creatively designed at the aspects of sensitive material, making condition, structure and the like of sensors; the sensitivity can be greatly increased; the testing repeatability is excellent; an unexpected technical effect is achieved; and the market application prospect is wide.

Description

technical field [0001] The invention belongs to the field of water heaters, and more specifically relates to a gas water heater for preventing vapor corrosion. Background technique [0002] Gas water heater, also known as gas water heater, refers to a gas appliance that uses gas as fuel and transfers heat to cold water flowing through a heat exchanger through combustion heating to achieve the purpose of preparing hot water. [0003] Because the energy required for the operation of gas water heaters comes from gas, which is a flammable and explosive gas, the environment where gas water heaters are generally placed is relatively high humidity, and water vapor will cause corrosion and other effects on the components of the gas water heater, which are generally not available in existing gas water heaters. Humidity detection function. Contents of the invention [0004] Aiming at the problems in the background technology, the present invention provides a gas water heater for pr...
