Intelligent water temperature and quantity control device

Abstract

The invention discloses an intelligent water temperature and quantity control device. The intelligent water temperature and quantity control device is characterized in that two water flow meters, two water temperature sensors and two electromagnetic valves are respectively mounted at a cold water pipe and a hot water pipe, received water flow signals and received water temperature signals are combined with one another by a controller, and then the controller transmits instructions by the aid of a PID (proportion, integration and differentiation) algorithm so as to accurately control on and off of the cold water electromagnetic valve and the hot water electromagnetic valve; a water temperature sensor is further mounted on a water outlet pipe of a water mixing device, and water temperature signals of water mixed by a water mixing chamber are fed to the controller. The intelligent water temperature and quantity control device has the advantages that the temperature and the quantity of water discharged by the water outlet pipe can be accurately adjusted, the total water quantity of water used during bathing can be displayed, and accordingly bathing environments required by users can be created.

Description

technical field [0001] The invention designs a water temperature and water volume control device, in particular to an intelligent water temperature and water volume control device. Background technique [0002] Due to the popularization of family and personal bathrooms, the traditional bathroom water temperature regulation is generally to install a cold and hot water regulating device. The common ones are manual control device and automatic control device. The manual control device adjusts the temperature of the mixed bath water by controlling the opening of the cold and hot water valves. The disadvantage of this control method is that it wastes cold and hot water resources. The water temperature fluctuates greatly. The automatic control device detects the water temperature of the water pipe through the temperature sensor, and then feeds back to the microcontroller to control the opening of the cold and hot water solenoid valves to adjust the water temperature. The water mi...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the existing water temperature control device cannot accurately control the amount of cold and hot water to be added during use, the water temperature after mixing still fluctuates greatly, and cannot control the water output per unit time when the user is bathing. It is impossible to measure the lack of water used by the user for a bath, but an intelligent water temperature and water volume control device that can accurately control the amount of cold and hot water per unit time and accurately control the temperature of bath water
