Automatic flushing apparatus of membrane filter in water purifier

Abstract

A water purifier includes a sediment filter (100), a pre-activated carbon filter (200) and a membrane filter (300) to sequentially filter raw water. The automatic flushing equipment of membrane filter (300) comprises LPS (120), and it is used for detecting the water pressure in the water pipe that is connected between sediment filter (100) and pre-activated carbon filter; Pump (130), its Used to pump the water supplied from the sediment filter (100) to the pre-activated carbon filter (200); the controller (600) is used to control the flow of water from the membrane from the time point when the pumping voltage is detected. flushing of the inside of the filter (300); and a flushing regulator valve (310) for opening the flushing pipe of the membrane filter (300). Water is flushed out from the inside of the membrane filter (300) through the flushing regulating valve (310), and at the same time, under the flushing pressure of the water flushed out from the inside of the membrane filter (300), the Limescale removed.

Description

technical field [0001] The present invention relates to the automatic flushing equipment of the membrane filter in the water purifier, more specifically, this automatic flushing equipment can automatically flush water from inside the membrane filter with a predetermined time period according to the purification time of the membrane filter, so that the Scale is periodically and automatically removed from the inside of the membrane filter by the pressure of the water flushed from the inside of the membrane filter. Background technique [0002] In general, water purifiers are designed to filter out impurities (or scale) such as harmful carcinogens from raw water such as tap water (drinking water), and thus provide clean purified water. According to the type of purification, water purifiers can be divided into purifiers using natural filtered water, tap water purifiers, purifiers using ion exchange resins, purifiers using reverse osmosis, and the like. [0003] Among such conve...

Problems solved by technology

[0010] However, such a conventional water purifier has a disadvantage in that the scale inside the membrane filter is removed by manual operation of the manual valve, so the user will detect the time point of scale removal, and the scale removal process is troublesome

[0011] In addition, since this descaling process is performed by the user's inspection and manual operation, there are not enough times for descaling

If the scale is not descaled frequently enough, the service life of the membrane filter will be shortened
