Fire size remote regulating device with sensitivity cold temperature compensation of gas water heater

Abstract

The invention discloses a fire size remote regulating device with sensitivity cold temperature compensation of a gas water heater. The fire size remote regulating device consists of a first flow measuring unit, a second flow measuring unit, an adder circuit unit, a cold water temperature measuring unit, a proportional value calculating unit, a flow threshold value switching unit and a proportional valve drive unit. The gas water heater comprises a first hot water outlet and a second hot water outlet, and the hot water temperature is changed by adopting a method of controlling two-way hot water flow through a water valve; when the hot water flow of the first hot water outlet is relatively increased, burning fire of the gas water heater is increased, and the hot water temperature is increased; when the hot water flow of the first hot water outlet is relatively reduced, the burning power of the gas water heater is reduced, and the hot water temperature is reduced; and regulating sensitivity is subjected to compensation control by virtue of the inlet cold water temperature of the water heater. According to the device, a wired or wireless remote controller is not required, remote regulation on the hot water temperature of the gas water heater can be realized, and the control results are stable and reliable.

Description

technical field [0001] The invention relates to a gas water heater, in particular to a gas water heater with a firepower remote adjustment device with sensitivity cold water temperature compensation. Background technique [0002] If the temperature of the gas water heater is not set properly, it will bring great inconvenience, 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 lead to gas The water heater is turned off. 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...

Problems solved by technology

[0002] If the temperature of the gas water heater is not set properly, it will bring great inconvenience, 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 lead to gas water heater off

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.
