Combustion power remote adjustment device for gas water heater with sensitivity cold water heat capacity compensation

Abstract

The invention discloses a combustion power remote adjustment device with sensitivity cold water heat capacity compensation for a gas water heater, which comprises a first flow measurement unit, a second flow measurement unit, an adder circuit unit, a sensitivity calculation unit, a proportional value calculation unit, and a flow threshold switch Unit and proportional valve drive unit. The gas water heater includes a first hot water outlet and a second hot water outlet, and the temperature of the hot water is changed by remotely controlling the two-way hot water flow through a water valve; when the hot water flow of the first hot water outlet increases relatively, When it is large, the combustion power of the gas water heater increases and the temperature of the hot water rises; when the flow of hot water at the first hot water outlet decreases relatively, the combustion power of the gas water heater decreases and the temperature of the hot water decreases; the adjustment sensitivity is determined by the heat capacity of the cold water at the inlet of the water heater The size is compensated for control. The device does not need a wired or wireless remote controller, can realize remote adjustment of the hot water temperature of the gas water heater, and the control result is stable and reliable.

Description

technical field [0001] The invention relates to a gas water heater, in particular to a gas water heater with a combustion power remote adjustment device with sensitivity cold water heat capacity 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 en...

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.
