[0002] Regardless of whether it is a gas water heater or an electric water heater, the hot water is used to end the use of hot water by closing the hot water valve, but in this way, a lot of hot water remains in the water heater and on the pipeline, and gradually cools down, which is academically said to be useless The hot water is invalid hot water. When using hot water, when the hot water valve is opened, the temperature of the outgoing water will gradually rise. , the water temperature at the outlet of the water heater is also the highest. It is a pity that such high-temperature hot water cannot be used. Especially for gas water heaters, when the hot water valve is closed, there will be a delay of 3 to 5 seconds. The length of the delay time It depends on the length of the pipeline, until the electronic controller equipped with the water heater detects that the water pressure of the water pan is insufficient, it will output a signal to inform the main furnace that the electromagnetic valve is closed and the flame is turned off. At this time, the hot water inside the water heater has reached a high temperature and If there is no flow, but still accepting the extra 3 to 5 seconds of heating, the water temperature will rise even higher, which not only wastes energy, but also makes the water heater more likely to accumulate scale, which also causes the heat exchange efficiency to become worse and worse, and affects the service life and safety of the water heater

Embodiment Construction
[0084] Now the control method, flow process, function and device of the present invention are introduced:
[0085] Please refer to figure 1 , the present invention mainly consists of a group of high-frequency transmitter 1, and high-frequency receiver 2, constitute the main control unit, with a group of wireless transmitter 3, and wireless receiver 4, as an auxiliary unit, and the input command is made of waterproof After the button 11 is pressed, the water heater and the wireless transmitter 3 can be controlled respectively by the two contacts 30 and 31 of the output of the high-frequency receiver 2 through wireless transmission.
[0086] Please refer to figure 2 , the power supply of the high-frequency transmitter 1 is a dry battery 10, when the hot water user will finish using it about 50 seconds to more than a minute, press the waterproof button 11, and then detect the circuit 12, and the button 11 can be detected , has issued an instruction, through the coding amplifie...

The invention provides a method and device for controlling a water heater capable of saving energy and preventing scale. The method and device for controlling the water heater capable of saving energy and preventing scale can be applied to gas and electric water heaters, enable a hot water user to stop energy supply through a remote control switch before usage is finished, send an acousto-optic signal to remind the user to make confirmation, enables the remaining hot water in the water heater and a pipeline to be continuously used and can prevent scale from being produced in the water heater.
Description
technical field [0001] The present invention relates to a kind of energy saving of two types of water heaters, such as liquefied gas or natural gas water heaters (collectively referred to as gas water heaters above), and electric water heaters of instantaneous heating or thermal storage type (the above two electric water heaters are collectively referred to as electric energy water heaters). And a control method and device for preventing scale formation. Background technique [0002] Regardless of whether it is a gas water heater or an electric water heater, the hot water is used to end the use of hot water by closing the hot water valve, but in this way, a lot of hot water remains in the water heater and on the pipeline, and gradually cools down, which is academically said to be useless The hot water is invalid hot water. When using hot water, when the hot water valve is opened, the temperature of the outgoing water will gradually rise. , the water temperature at the outle...
