[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.

Embodiment Construction
[0028] Hereinafter, the present invention will be further described in detail with reference to the examples and drawings, but the implementation of the present invention is not limited thereto.
[0029] The principle block diagram of the remote adjustment device of the gas water heater firepower is as follows figure 1 As shown, it is composed of a first flow measurement unit 100, a second flow measurement unit 200, a proportional value calculation unit 300, a flow threshold switch unit 400 and a proportional valve drive unit 500.
[0030] The gas water heater has one cold water inlet and two hot water outlets. A flow sensor is installed at the cold water inlet and one of the hot water outlets to detect the water flow respectively. The first flow measurement unit 100 measures the outlet hot water flow Q1 of one of the hot water outlets, and the second flow measurement unit 200 measures the total inlet cold water flow Q2 of the cold water inlet and uses the first flow voltage U1 and ...

The invention discloses a device for remotely adjusting the firepower of a gas water heater, which is composed of a first flow measurement unit, a second flow measurement unit, a proportional value calculation unit, a flow threshold switch unit and a 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 firepower of the gas water heater increases, and the temperature of hot water rises; when the hot water flow rate of the first hot water outlet decreases relatively, the combustion firepower of the gas water heater decreases, and the temperature of hot water drops. 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 remote control device for the firepower of the gas water heater. Background technique [0002] If the temperature of the gas water heater is not set properly, it will cause great inconvenience, especially in the shower, the temperature of the gas water heater without wireless remote control or remote control cannot be adjusted, and adding cold water with the mixing valve will easily cause gas. The water heater turned off. Using wireless remote control to adjust the temperature of the gas water heater, due to the limitation of the installation location, in many cases the remote control signal cannot be transmitted to the gas water heater. When using the remote wire control method, the dedicated waterproof wired remote control is costly, it needs to be buried in advance, and it works in humid environments such as the bathroom for a long time. The electronic wired remote control has a high failur...
