Multipurpose domestic water purifier

Abstract

The invention discloses a multipurpose domestic water purifier which has the advantages of favorable sterilization effect, good water quality and good quality of effluent water and can centrally supply water everywhere in the whole house. The water purifier can simultaneously supply purified water with different purifying effects, and can still supply purified water in case of a power cut. The multipurpose domestic water purifier comprises a shell component (100), an electric control device, an ultrafiltration device (1), an activated carbon tank (2) and an ultraviolet sterilization device (3), wherein the shell component (100) is provided with connected with a tap water inlet (10), a primary purified water outlet (20), a secondary purified water outlet (30) and a direct drinking water outlet (40); a water inlet of the ultrafiltration device (1) is connected with the tap water inlet (10), a drainage port is connected with the primary purified water outlet (20), and a water outlet is connected with an inlet of the activated carbon tank (2); both ends of the activated carbon tank (2) are respectively provided with an outlet, and the two outlets are respectively connected with inlets of the secondary purified water outlet (30) and the ultraviolet sterilization device (3); and an outlet of the ultraviolet sterilization device (3) is connected with the direct drinking water outlet (40). The invention is applicable to the field of domestic water purification.

Description

technical field [0001] The invention relates to a multipurpose household water purifier. Background technique [0002] A household water purifier is a water purification device that purifies tap water. Existing household water purifiers have a single function and generally only have one or several stages of ultrafiltration treatment. Although the water quality can meet the general needs, the taste is not good.

Usually, a pre-filter is used as a primary filter product, and then a water purifier is used as drinking water for making tea, etc., plus a Ultrafiltration membrane products are used to purify domestic water such as laundry or washing, which leads to occupying space and is troublesome in management...

AI Technical Summary

Problems solved by technology

Existing household water purifiers have a single function, generally only one or several stages of ultrafiltration treatment, although the water quality can meet the general needs, but the taste is not good

Moreover, the existing household water purifiers are generally connected to a faucet, and it is difficult to meet the water demand of the whole house.

[0003] In addition, usually the water purifiers on the market are difficult to meet the water demand of the whole house. Usually, a pre-filter is used as a primary filter product, and then a water purifier is used as drinking water for making tea, etc., plus a Ultrafiltration membrane products are used to purify domestic water such as laundry or washing, which leads to occupying space, management, maintenance and installation are more troublesome

However, the existing central water purifiers on the market only purify, have no disinfection function, and cannot meet the standard for direct drinking.

Moreover, the existing water purifiers using RO reverse osmosis have a small water volume, which is difficult to meet the water demand of the whole house

[0004] In addition, the water purifiers on the existing market are often unusable during power outages and cannot obtain purified water, so they are greatly limited during power outages
