Embodiment Construction

[0020] To facilitate those skilled in the art to better understand the essence of the present invention, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 As shown, a power-on / off control system for an electric water heater includes: a water flow sensor 1, an electric water heater control system 2 and a leakage protection plug 3. The water flow sensor 1 is installed on the water inlet component or the water outlet component of the electric water heater The electric water heater control system 2 is connected to the electric water heater control system 2 to sense the water signal. The three poles of the leakage protection plug 3 can be disconnected and reset. The electric water heater control system 2 and the water flow sensor 1, the leakage protection plug 3 signal Connect and control all three poles of the leakage protection plug 3 to be disconnected or reset according to the sig...

Abstract

The invention discloses an electric water heater power on-off control system. The electric water heater power on-off control system comprises a water flow sensor, an electric water heater control system and a leakage protection plug; the water flow sensor is mounted on a water inlet component or a water outlet component of an electric water heater and connected with the electric water heater control system via signals; three poles of the leakage protection plug can be all disconnected, can return and have automatic timing functions; when the water flow sensor detects that a user is using water, the electric water heater control system transmits an instruction of enabling the leakage protection plug to trip; the leakage protection plug is disconnected with three poles of an electric water heater power supply, so that the user takes a shower in a safe environment; meanwhile, a timer within the leakage protection plug begins to time; after reaching a set time, the leakage protection plug returns to be connected with the three poles of an electric water heater power supply; after the three poles of an electric water heater power supply recovers, the electric water heater works in a normal state.

Description

Technical field [0001] The invention relates to the technical field of electric water heater control, in particular to an electric water heater on and off control system. Background technique [0002] The storage-type electric water heater has an inner tank, and the hot water stored in the inner tank is usually used when taking a bath, so the power supply may not be connected. In the prior art, in order to improve the safety of the electric water heater, some users press the test button of the leakage protection plug before taking a bath to disconnect the three poles (zero, fire, and ground wire) of the electric water heater, and press the leakage protection after bathing. The reset button of the plug can power on the electric water heater. Some household electric water heaters are installed in a high position, which causes difficulty in operation and a bad experience. Summary of the invention [0003] In view of the problems in the prior art, the purpose of the present invention...
