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.

Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0033] The principle block diagram of the hot water temperature remote adjustment device of the gas water heater is as follows figure 1 As shown, it consists of a first flow measurement unit 100 , a second flow measurement unit 200 , an adder circuit unit 300 , a proportional value calculation unit 400 , a flow threshold switch unit 500 and a proportional valve drive unit 600 .

[0034]The gas water heater has 1 cold water inlet and 2 hot water outlets, and flow sensors are respectively installed at the 2 hot water outlets to respectively detect the outlet hot water flow of the 2 hot water outlets. The first flow measurement unit 100 is provided with a first flow voltage U1 output terminal, and the second flow measurement unit 200 is provided with a second flow voltage U...

Abstract

The invention discloses a control method of a gas proportional control valve of a gas water heater. The gas water heater comprises a first hot water outlet, a second hot water outlet, a relay gas switch and the gas proportional control valve. Through detecting the outlet hot water flow of the first hot water outlet and the outlet hot water flow of the second hot water outlet, an outlet hot main flow is obtained, and the ratio of the outlet hot water flow of the first hot water outlet to the outlet hot water main flow is calculated for obtain proportion value control voltage. When the proportion value control voltage is increased, the opening degree of the proportional control valve is controlled to be increased, and the temperature of the water heater rises. When the proportion value control voltage is decreased, the opening degree of the proportional control valve is controlled to be decreased, and the temperature of the water heater is reduced. According to the method, a wire or wireless remote controller is not needed, remote adjusting of the hot water temperature of the gas water heater is achieved, and the control result is stable and reliable.

Description

[0001] The patent application for this invention is a divisional application, the original application number is 201610000437.4, the application date is January 4, 2016, and the invention name is a remote adjustment device for hot water temperature of a gas water heater. technical field [0002] The invention relates to a control method of a gas water heater, in particular to a control method of a gas proportional regulating valve 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 location, the remote cont...
