Method for regulating combustion power of gas water heater

Abstract

The invention discloses a method for regulating combustion power of a gas water heater. The gas water heater comprises two hot water outlets and a cold water inlet. The combustion power is controlled by a ratio of outlet hot water flow of a second hot water outlet to inlet cold water flow of the cold water inlet according to a regulation sensitivity; when the ratio of the outlet hot water flow of the second hot water outlet to the inlet cold water flow of the cold water inlet is increased, the combustion power is controlled to be reduced; conversely, the combustion power is controlled to be increased; a size of the regulation sensitivity is controlled by an inlet cold water temperature of the cold water inlet; when the inlet cold water temperature of the cold water inlet is reduced, the regulation sensitivity is controlled to be increased; conversely, the regulation sensitivity is controlled to be reduced. The method does not require a wired or wireless remote controller, can achieve remote regulation on the combustion power of the gas water heater, and is stable and reliable in regulation result.

Description

technical field [0001] The invention relates to a gas water heater control technology, in particular to a method for adjusting combustion power of a gas water heater. Background technique [0002] If the temperature of the gas water heater is not set properly, it will bring great inconvenience to people, especially in the shower, the temperature of the gas water heater without wireless remote control or remote wire control cannot be adjusted, and adding cold water with the mixing valve will easily cause the gas water heater to be damaged. turn off the flame. The wireless remote control is used to adjust the temperature of the gas water heater. Due to the limitation of the installation location, the remote control signal cannot be transmitted to the gas water heater in many occasions. When the long-distance wire control method is used, the special waterproof wired remote control is expensive, and it needs to be embedded in advance. It works in a humid environment such as a b...

Problems solved by technology

[0002] If the temperature setting of the gas water heater is inappropriate, it will bring great inconvenience to people, especially in the shower, the temperature of the gas water heater without wireless remote control or long-distance wire control cannot be adjusted, and adding cold water with the mixing valve will easily cause the gas water heater to be damaged. flameout

Use wireless remote control to adjust the temperature of the gas water heater. Due to the limitation of the installation location, the remote control signal cannot be transmitted to the gas water heater in many occasions.

When the long-distance wire control method is adopted, the cost of the dedicated waterproof wired remote control is high, and it needs to be buried in advance, and it has been working in a humid environment such as a bathroom for a long time, and the failure rate of the electronic wired remote control is high.
