Bucketless water purifier control system

Abstract

The invention discloses a control system for a barrel-free water purification machine. The control system comprises a rectifying voltage-stabilizing module, a waterway control solenoid valve, a flushing solenoid valve, a time relay and a normally open high-voltage switch, wherein a low-voltage switch, a normally closed high-voltage switch and a booster pump are successively connected with an anode output end of the rectifying voltage-stabilizing module; the waterway control solenoid valve and the booster pump are connected in parallel; the time relay comprises four ports J1-J4, wherein J1 and J2 are input ends and are connected with the output end of the normally closed high-voltage switch through the normally open high-voltage switch, J3 and J4 are output ports, J3 is connected with the input end of the flushing solenoid valve and is used for controlling the switch-on / off of the solenoid valve, and J4 is connected with a cathode of the rectifying voltage-stabilizing module. The control system for the barrel-free water purification machine provided by the invention is characterized in that the flushing is performed after the water is prepared, the water preparation is free from waiting, the use habit of the user is met, the flushing time can be set according to the requirement, the suitability for water quality in different areas is wide and the working requirement of the instant-preparing instant-drinking barrel-free water purification machine is met.

Description

technical field [0001] The invention relates to a bucketless pure water machine control system. Background technique [0002] After the control circuit of the pure water machine in the prior art is connected to the circuit, both the booster pump and the water flow control solenoid valve start to work, and at the same time, the flushing solenoid valve also starts to work, first flushing, and then water production, reaching the preset time of the flushing solenoid valve After that, it stops and enters the state of water production. Obviously, this type of pure water machine needs to wait in the process of water production, which does not meet the user's habits. At the same time, the flushing time is preset by the flushing solenoid valve and cannot be set as needed. Contents of the invention [0003] (1) Technical problems to be solved [0004] The purpose of the present invention is to overcome the above disadvantages, aiming to provide a bucketless water purifier control s...
