Electronic adjustable constant temperature water outlet solar water heater controller

Abstract

The invention relates to an electronic adjustable constant temperature water outlet solar water heater controller, and belongs to the field of civilian solar water heaters. The electronic adjustable constant temperature water outlet solar water heater controller comprises a switching power supply, an A/D converter, a single chip microcomputer, a driving circuit, a nixie tube display, a display circuit, four setting key switches and an IO line row; the switching power supply is connected with each of the A/D converter, the single chip microcomputer, the driving circuit and the display circuit;the four setting key switches are connected with the single chip microcomputer; the single chip microcomputer is connected with the driving circuit and the display circuit simultaneously; the drivingcircuit is connected with the IO line row; the IO line row is connected with the A/D converter; the A/D converter is connected with the single chip microcomputer; and the display circuit is connectedwith the nixie tube display. The electronic adjustable constant temperature water outlet solar water heater controller can receive temperature information of hot water and cold water, respectively open a cold water valve and a hot water valve to a certain degree according to a degree internal algorithm according to a set water outlet temperature, and perform closed-loop control by information feedback of a warm water temperature sensor to obtain an accurate water outlet temperature.

Description

technical field [0001] The invention relates to a controller for an electronically adjustable constant temperature outlet solar water heater, belonging to the field of civil solar water heaters. Background technique [0002] The controllers used in existing solar water heaters have simple functions. Most of them can only control the two states of fully open or fully closed of a water inlet solenoid valve, but cannot control the opening of the cold water and hot water pipes, resulting in the temperature adjustment of the outlet water cannot be electronically controlled. Contents of the invention [0003] The object of the present invention is to propose an electronically adjustable constant temperature outlet solar water heater controller to overcome the simple function of the existing solar water heater controllers, most of which can only control two states of a water inlet solenoid valve fully open or fully closed, and cannot Controlling the opening of the cold water and ...
