Water supply system for water purifier and control method thereof

Abstract

The invention discloses a water supply system for a water purifier and a control method. The water supply system comprises a raw water pipeline, a water purification system and a water outlet pipeline, wherein the raw water pipeline is connected with an inlet of the water purification system; the water outlet pipeline is connected with an outlet of the water purification system; a flowrate detection device is arranged on a water path of the water supply system, and is connected with a control device of the water purification system; in the process of making water in the water purification system, the control device is used for at least controlling the work state of the water purification system according to the information detected by the flowrate detection device. The water supply system can be used for controlling the work state of the water purification system according to water current information and water supply pressure, so that the system can enter a protection mode under a water shortage state, and the damage of water shortage operation for the whole machine can be prevented. Furthermore, the flowrate detection device is matched with a pressure detection device, the use amount of parts and components is reduced, and the system structure is simplified.

Description

technical field [0001] The invention relates to the related technical field of water purifiers, in particular to a water supply system of a water purifier and a control method thereof. Background technique [0002] The operation of the water purifier in the state of water shortage will seriously damage some components of the water purifier. In the existing water purifier, a low-voltage switch is usually set to solve the problem of water shortage operation. When the water purifier is short of water, the low-voltage switch controls the disconnection of the whole machine. After the low-voltage switch detects the low-pressure signal, it disconnects the whole machine through the water inlet valve; however, the setting of the low-voltage switch will occupy a certain space and make the structure of the whole machine more complex. Due to the limited structure of some water purifiers, the electrical components must be simplified, so that the whole machine cannot detect the lack of w...

AI Technical Summary

Problems solved by technology

When the water purifier is short of water, it controls the disconnection of the whole machine through the low-voltage switch. After the low-voltage switch detects the low-voltage signal, it disconnects the whole machine through the water inlet valve; however, the setting of the low-voltage switch will occupy a certain space and make the structure of the whole machine more complex

Due to the limited structure of some water purifiers, the electrical components must be simplified, so that the whole machine cannot detect the lack of water without a low-voltage switch and shut down, which has a certain impact on the service life of the water purifier.
