Gas water heater combustion power regulating circuit

Abstract

The invention discloses a gas water heater combustion power regulating circuit. The gas water heater combustion power regulating circuit comprises a sensitivity detection unit, a proportional value calculation unit and a proportional valve driving unit. A gas water heater comprises a first hot water outlet, a second hot water outlet, a cold water inlet and a gas proportion regulating valve. The method of controlling the relative volume of the flow of two paths of hot water remotely through a water valve is adopted, and a regulating signal is provided to the gas water heater to the proportionalvalue calculation unit; control over the sensitivity of the opening degree of the gas proportion regulating valve is achieved through the mode that the sensitivity detection unit detects the cold water temperature at the inlet and outputs sensitivity control voltage to the proportional value calculation unit; and the proportional value calculation unit outputs proportional value control voltage to control the opening degree of the gas proportion regulating valve. According to the method, no wired or wireless remote controller is needed, and long-distance regulation of the combustion power ofthe gas water heater can be achieved.

Description

[0001] The patent application for this invention is a divisional application, the original application number is 201610000436.X, the application date is January 4, 2016, and the invention name is a combustion power remote adjustment device for gas water heater with sensitivity cold water temperature compensation. technical field [0002] The invention relates to a gas water heater control technology, in particular to a combustion power regulating circuit of a gas water heater. Background technique [0003] 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 l...

Problems solved by technology

[0003] 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.
