Intelligent constant temperature and pressure water mixer for bathing, and control method thereof

Abstract

The invention particularly relates to an intelligent constant temperature and pressure water mixer for bathing, and a control method thereof. The water mixer comprises a hot water regulating valve, acold water regulating valve and a pressure increasing valve; the temperature of hot water, the temperature of cold water and the voltage of a water outlet are collected through sensors, and transmitted to a controller; the controller sends control signals to corresponding control circuits of the hot water regulating valve, the cold water regulating valve and the pressure increasing valve for controlling the opening degree of the corresponding valves, so that the constant temperature control over water is achieved; and through control over the rotating speed and rotating direction of the pressure increasing valve, the constant pressure control over output water is achieved. According to the intelligent constant temperature and pressure water mixer, water temperature and pressure are controlled through a closed loop control system, and the control of the water mixer is simple and reliable; complex algorithms and a powerful controller are not required; thus, the water mixer has less potential fault points, and the cost is lower; the temperature and pressure of warm water at the water outlet can be regulated accurately, so that the problems of complex manual temperature control and uneasy control are solved thoroughly.

Description

technical field [0001] The invention relates to the field of valve technology and automatic control, in particular to an intelligent constant temperature and constant pressure water mixer for bathing and a control method thereof. Background technique [0002] Mixing valves are widely used in daily life and industrial applications. When adjusting the temperature of the mixing valve used, some of them manually adjust the flow of hot and cold water. When adjusting manually, it is necessary to measure the temperature with a thermometer or other products to facilitate understanding of the current temperature. , to make appropriate temperature adjustments, so that the adjusted temperature reaches the corresponding suitable temperature. [0003] For example: application announcement number: 108223848A, the name of the invention is: a thermostatic mixing valve for automatic temperature adjustment of hot and cold water; Mixing valves, but there are the following problems: (1) the e...

Problems solved by technology

[0006] Aiming at the above-mentioned technical problems, the present invention provides an intelligent constant temperature and constant pressure water mixer for bathing; the present invention can solve the problem that manual temperature control is cumbersome and difficult to control, and at the same time can solve the problem that the manual temperature control valve cannot adjust the water when the external pressure changes. pressure problem; solve the problem that the existing electronic thermostatic regulating valve can only adjust the water temperature only; solve the problem that the existing booster device cannot adjust the water pressure well, or the pressure regulation is unstable; solve the problem that the previous products only guarantee constant temperature, It is not very convenient to stop the water in the middle; solve the problem of control accuracy; solve the problem that the adjustment range is not set according to the actual water temperature of the system
