Intelligent sensing water-saving device using frequency conversion technology

Abstract

The invention relates to a water-saving device, in particular to a water-saving device using intelligent sensing. The water-saving device comprises a water heater, electromagnetic valves, a pressure sensor, a constant pressure water supply converter, a hot water pipeline, a cold water pipeline and a water mixture pipe. Each of the hot water pipe, the cold water pipe and the water mixture pipe is provided with a water-saving valve; each water-saving valve is provided with a temperature control element inside; each temperature control element comprises a temperature sensor and a temperature controller. The temperature sensors are arranged on a cold-and-hot water pipeline; the input end of each temperature controller is connected with the output end of each temperature sensor; the output end of each temperature controller is connected with one water-saving valve and one electromagnetic valve. A cold water inlet of each temperature control element is connected with one water outlet of the cold water pipeline; a hot water inlet of each temperature control element is connected with one hot water outlet of the water heater; a cold-and-hot water pipe outlet of each temperature control element is connected with a water consumer unit through one electromagnetic valve; the other end water outlet of every electromagnetic valve is connected with the cold water pipeline; the output end of the pressure sensor is connected with the input end of the constant pressure water supply converter; the output end of the constant pressure water supply converter is connected with the cold water pipeline; a water inlet of the cold water pipeline is externally connected with a water supply pipeline.

Description

technical field [0001] The invention relates to a water-saving device, in particular to an intelligent induction water-saving device using frequency conversion technology. Background technique [0002] In our daily life, as soon as we turn on the faucet, the water will flow out continuously, and we may not feel the crisis of water at all. But in fact, the water we depend on for survival is becoming increasingly scarce. The waste of water is staggering. A faucet that is not closed tightly can drain 1-6 cubic meters of water a month; a leaky toilet can drain 3-25 cubic meters of water a month. If there are 600,000 faucets and 200,000 toilets leaking in the city , will lose hundreds of millions of cubic meters of water a year. At present, many cities have water shortages, seriously affecting the normal life of residents and the production and operation of enterprises. Most homes, hotels, sauna centers and other places use centralized water supply. When showering, it is comm...
