Electro-thermal water faucet

Abstract

The invention relates to an electro-thermal water faucet. The electro-thermal water faucet is characterized in that an water inlet pipe (10) is communicated and connected with a cooling water pipe and a heater (5), the inside of the heater (5) is a cavity channel structure formed as a flowing channel for the cooling water to be heated, the other ends of the cooling water and the pipe and heater (5) are respectively communicated and connected with a water diversion flange cooling water outlet (71) and a water diversion flange hot water outlet (73) on a water diversion flange (7), the heater (5) is internally provided with heating pieces (50) and heater sealing splints (51) extending along the direction of stream, the heater (5) is positioned in a column (1) in which a circuit board assembly (6) connected with a stream switch (8) and the heater (5) is arranged, and the heating pieces (50) are made of semiconductor insulating materials. The electro-thermal water faucet can simultaneously access cooling and hot water with clear separation of cooling and hot functions and non-interfering cooling and hot water paths, is controlled by a microcomputer circuit and has such protection functions as burnout resistance, over-temperature resistance, electrical leakage prevention and grounding production, and has strong safety.

Description

technical field [0001] The invention relates to a water faucet, in particular to an electric water faucet with instant heating function. Background technique [0002] At present, the faucets with heating function on the market have a single function and can only use hot water. If hot water is not needed, the power supply needs to be cut off, which is troublesome to operate. Most of the faucets with heating function on the market use metal resistance wire heating tubes for heating. Metal resistance wire heating tubes are easy to attenuate, scale, and easily damage leakage. In addition, these faucets have poor safety performance and lack the necessary anti-dry and leakage protection functions. The products on the market are generally simple in structure, with disordered functional areas, unable to carry out effective maintenance, and waste a lot of resources. [0003] Therefore, need badly a kind of electric water faucet that adopts new structure to overcome above-mentioned ...
