Water purifier capable of preventing water seepage and control method thereof

Abstract

The invention provides a water purifier capable of preventing water seepage and a control method thereof. The water purifier capable of preventing water seepage is provided with a filtration system, a water inlet valve, a drainpipe, a waste water valve, a water outlet pipe and a water outlet valve, wherein a water inlet of the filtration system is hermetically communicated with a water inlet pipe; the water inlet valve is arranged on a water inlet pipeline of the filtration system; the water outlet pipe is hermetically communicated with a waste water outlet of the filtration system; the waste water valve is arrange on the drainpipe; the water outlet pipe is hermetically communicated with a purified water outlet of the filtration system; the water outlet valve is arranged on the water outlet pipe; and the water outlet valve is a normally-open valve, is totally opened when power is not supplied and only has one small hole to allow water to pass through when power is supplied. The control method comprises the following steps: during preparation of water, controlling opening of the water inlet valve and closing of the waste water valve when power is supplied; during flushing, controlling opening of the water inlet valve when power is supplied and opening of the waste water valve when power is not supplied; and when the water purifier is in a standby state after completion of water production, controlling closing of the water inlet valve when power is not supplied and opening of the waste water valve when power is supplied. The water purifier can prevent water leakage accidents.

Description

technical field [0001] The invention relates to the technical field of water purification equipment, in particular to a leak-proof water purifier and a control method thereof. Background technique [0002] In recent years, water purification products have attracted more and more attention from consumers as health products, and the water purification industry has also developed rapidly. The reverse osmosis water purifier has the characteristics of clean water and has been widely used in the field of water purification equipment. The reverse osmosis water purifier needs to apply a large water pressure in front of the reverse osmosis membrane to permeate tap water or other water that needs to be purified to obtain pure water. In order to protect the reverse osmosis membrane, waste water is discharged while producing water, and the surface of the reverse osmosis membrane is washed. [0003] In the water purification equipment in the prior art, a waste water valve is arranged i...

AI Technical Summary

Problems solved by technology

When the water inlet solenoid valve is damaged, the tap water pressure enters the water purifier. Due to the action of the waste water valve, the water pressure cannot be released, so that the internal pipeline and water storage tank of the water purifier are subjected to tap water pressure for a long time, resulting in the risk of water leakage.
