Embodiment Construction

[0037] In order to facilitate those skilled in the art to better understand the essence of the present invention, the specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0038] Such as figure 1 As shown, an electric water heater water outlet and power failure control system to prevent misoperation, including: including: a three-pole leakage protection plug power cord 1 that can be automatically reset, an electric water heater main controller 2, an isolated communication module 3 and a water flow sensor 4 .

[0039] Wherein, the automatically resettable three-pole leakage protection plug power cord 1 is connected to the power supply line of the electric water heater, and is a power cord with a leakage protection plug, which can realize three-stage disconnection of the leakage protection plug.

[0040] The water flow sensor 2 is installed on the water inlet or outlet waterway of the electric...

Abstract

The invention discloses an electric water heater water output power-off control system capable of preventing misoperation. The electric water heater water output power-off control system is characterized in that the system comprises a tripolar electric leakage protection plug power line capable of automatically resetting, an electric water heater master controller, an isolation communication module and a water flow sensor; the tripolar electric leakage protection plug power line is connected to a power supply line of an electric water heater; the electric water heater master controller is connected with the water flow sensor and connected with the tripolar electric leakage protection plug power line through the isolation communication module; and on-off of three poles of the tripolar electric leakage protection plug power line is controlled by the electric water heater master controller according to signals provided by the water flow sensor. In the electric water heater water output power-off control system, the isolation communication module controls on-off of the three poles of the electric leakage protection plug power line according to the magnitude (threshold conditions) of water flow signals detected by the water flow sensor, and misoperation of the electric leakage protection plug power line can be avoided on the premise of guaranteeing water safety of a user.

Description

technical field [0001] The invention relates to the technical field of electric water heater control, in particular to a water outlet and power cut control system for an electric water heater to prevent malfunction. Background technique [0002] In the prior art, after the user's water behavior is collected through the water flow sensor, the electric heater is driven to be powered off through logic control, so as to ensure that the user will not get an electric shock due to electric leakage. However, because the power line of the leakage protection switch and the controller are still charged, and some leakage accidents are caused by poor grounding or electrification of the ground wire, it is impossible to completely guarantee the user's bathing safety, and there is a safety risk. [0003] In order to improve safety performance, some users press the test button of the leakage protection plug to disconnect the three poles (zero, fire, ground) of the electric water heater befor...
