Water purifier

Abstract

The invention discloses a water purifier, comprising a raw water storing device, a pressurizing device, a primary filtering device, a reverse osmosis treatment device, a wastewater recovering pipeline device and a purified water storing device, wherein the wastewater recovering pipeline device can be used for returning wastewater generated by the reverse osmosis treatment device to the raw water storing device for circulating and purifying again, so that the utilization efficiency of wastewater is improved. In the water purifier, the raw water storing device is adopted to receive raw water and wastewater; the raw water and the wastewater are fully mixed and then introduced into a next water producing cycle; the raw water storing device is not easy for bacteria breeding; the water producing efficiency and the wastewater utilization efficiency are improved by using a proportional controller arranged on the wastewater recovering pipeline device; and incoming water in the raw water storing device can be automatically introduced or manually fed. The water purifier can be used in a kitchen, a living room or a bedroom and is not limited by places; meanwhile, wastewater generated by the reverse osmosis treatment device is filtered by a compound filter element and then returns to the raw water storing device, so that the concentration of wastewater is reduced, the burden of a filtering system during next water producing cycle is reduced and the service life of the filtering system is ensured.

Description

technical field [0001] The invention is a water purifier, which belongs to the innovative technology of the water purifier. Background technique [0002] With the improvement of people's living standards, the requirements for the quality of drinking water are also getting higher and higher. Therefore, in the past ten years, reverse osmosis treatment technology has been gradually introduced from the industrial field to the civilian field, and has developed into the form of terminal purification. Although the reverse osmosis treatment technology has many advantages, it also produces a large amount of wastewater when it produces pure water or clean water. These wastewaters have relatively high ion content and are directly discharged, resulting in a great waste of water resources. [0003] Chinese patent document CN201164379Y discloses a water-saving reverse osmosis direct drinking water machine, which includes a water storage tank, a primary filter device, a reverse osmosis tr...

Problems solved by technology

But this type of water dispenser, because the water tank is divided into the raw water chamber and the waste water chamber, the waste water chamber is in the state of full water for a long time to breed bacteria easily and the waste water recycling rate is not high; and the waste water produced by the reverse osmosis treatment device has not been treated If it is directly returned to the original water tank after treatment, it will affect the service life of the reverse osmosis membrane; and the water can only be fed by connecting the water pipe instead of manually adding water, and the scope of use is limited
