A zero-ground wire potential difference detection device comprises a transformer, an equalizer and a switch transistor, and connects to the input end of the microcontroller. The output of a triode switch circuit is connected with a relay coil, and the normally open contact circuits of the relay are separately connected with the live wire and the zero wire. The utility model has the beneficial effects that the power supply of the electrical heating tube can be automatically cut when the drinking-water machine is in use, at preset time, or not in use, the zero-ground wire potential difference detection device can provide electric leakage signal of the electrical heating tube, thereby the deficiency that the electric leakage of the electrical heating tube leads to water charging and jeopardizes human safety is overcome.
Description
Technical field
The utility model relates to a kind of electricity-saving electricity-guard socket, particularly a kind of intelligent electricity-saving electricity-guard socket of drinking machine.
Background technology
Before the utility model, the water dispenser attaching plug directly inserts the body of wall socket, no matter evening on daytime the and whether someone uses, all heats repeatedly, causes waste of power resources.The electric leakage of electric heating tube will cause in the water chargedly when the earth-free line of water dispenser socket, jeopardize user's personal safety.
Summary of the invention
The purpose of this utility model provides a kind of intelligent electricity-saving electricity-guard socket of drinking machine.
The technical scheme that its technical problem that solves the utility model adopts is: the utility model comprises ultrasonic sensor and zero grounding potential difference detector set; Time is provided with circuit, ultrasonic sensor circuit, zero grounding potential difference detector set and transistor switching circuit and is connected with the I/O input/output terminal of single-chip microcomputer respectively.Be provided with that circuit is provided with key by clock setting key, available machine time and LCDs is formed the time, clock setting key, available machine time are provided with key and are connected with the I/O input of singlechip chip respectively, and LCDs is connected with the I/O output of singlechip chip.The ultrasonic sensor circuit is by ultrasonic sensor, the ultrasonic wave driver module, and gate circuit connects to form, and receives the human-induced signal and is connected in the I/O input of singlechip chip.Zero grounding potential difference detector set is made up of transformer, rectifying device and switching tube, is connected with the single-chip microcomputer input.Transistor switching circuit is connected with the I/O output of singlechip chip, and the output of transistor switching circuit is connected with relay coil, and the relay normally open contact circuit connects live wire and zero line respectively.
The beneficial effects of the utility model are to have overcome the water dispenser attaching plug directly to insert the body of wall socket, because no warm-up time control device, no matter evening on daytime the and whether someone uses, all heat repeatedly, cause the defective of waste of power resources, a kind of type intelligent drinking machine electricity-saving socket is provided.This device makes water dispenser have switching on and shutting down function time memory by the water time set.Circuit is set and receives the ultrasonic sensor human-induced signal by the time, when using water dispenser or at the appointed time or certain hour is unmanned behind the Auto Power On cuts off the electric heating tube power supply when using, zero grounding potential difference detector set can provide the electric leakage signal of electric heating tube, the electric leakage that overcomes electric heating tube when the earth-free line of water dispenser socket will cause in the water charged, jeopardize the defective of personal safety.
