Wall hanging furnace three-way valve control device and assembling and connecting method thereof

Abstract

The invention discloses a wall hanging furnace three-way valve control device and an assembling and connecting method thereof. The wall hanging furnace three-way valve control device comprises an upper cover and a lower cover, a mounting space defined by the upper cover and the lower cover is internally provided with a mounting plate arranged on the lower cover , a bathroom microswitch, a heatingmicroswitch, a PCB, a motor arranged between the lower cover and the mounting plate, an ejection piece movably arranged on the side, close to the upper cover, of the mounting plate and a driving cam,wherein the bathroom microswitch, the heating microswitch and the PCB are arranged on the mounting plate; the bathroom microswitch and the heating microswitch are located between the mounting plate and the upper cover and located on one side of the PCB; the PCB is connected with the bathroom microswitch and the heating microswitch through an electric wire, and a lead of the motor is connected withthe PCB; and the ejection piece penetrates through the upper cover, the driving cam is located on one side of the bathroom microswitch and the heating microswitch, and the driving cam is connected with an output shaft, which penetrates through the mounting plate, of the motor and is abutted against the ejection piece. According to the device and the method, three 250 terminals are replaced by thePCB, so that the installation difficulty is reduced, and the assembly efficiency is improved.

Description

technical field [0001] The invention relates to a control device, in particular to a three-way valve control device for a wall-hung boiler and an assembly and connection method thereof. Background technique [0002] Three-way valves are widely used in wall-hung boilers, because in actual use, wall-hung boilers will alternately switch between the heating state and the sanitary state, and this conversion needs to be realized through a three-way valve. [0003] The three-way valve is easy to operate. When switching between waterways, you only need to change the power supply at both ends of the three-way valve; the three-way valve is generally one water inlet, one heating water outlet, and one bathroom water outlet. The power supply of the through valve can control the heating water or the bathroom water. At the same time, the three-way valve will only have one way of water out, and the other way out of water. The conversion of the three-way valve is realized by the three-way v...

AI Technical Summary

Problems solved by technology

[0004] The existing three-way valve control device for wall-hung boilers is simple to control and easy to switch waterways. When controlling the device, the 250 terminals need to be installed on the mounting board one by one. Due to the large number of 250 terminals, the assembly and connection steps are increased, and because the terminal installation accuracy is also required, the excessive number of terminals makes the three-way valve control device of the wall-hung boiler more difficult. The difficulty of assembly and connection also increases
