Abstract
The utility model relates to a single-chip wire-control device of a bathroom roof integrated electric appliance with security protection. The input end of a single chip is connected with a touch switch and a zero-ground line potential-difference detection circuit, the touch switch is used for controlling one of the integrated appliances such as the lamp heating, the air heating, the air exchanging, the lighting, the ventilation, an anion generator, etc and is used for controlling the time setting, and the setting of the timing closing. The zero-ground line potential-difference detection circuit consists of a transformer, a rectifying circuit and a switch tube, and the primary coil of the transformer is bridged over the zero line and the ground line of the power source. The output end of the single chip is connected with a liquid crystal display and a switch-tube execution circuit, the liquid crystal display displays the working status, and the switch-tube execution circuit controls the on-off of the integrated electric appliance. The single-chip wire-control device has the advantages that the bathroom roof integrated electric appliance is controlled by the touch switch, thereby being convenient to be used. The single-chip wire-control device overcomes the wet environment of the bathroom, and overcomes the weakness that when the ground line is electrified, the power source cannot be disconnected, thereby endangering the human body. The single-chip wire-control device is safe to use.
Description
Technical field
The utility model relates to a kind of wire-controlled apparatus of electrical equipment, particularly a kind of wire-controlled apparatus with bath top integrated device of safeguard protection.
