Combined reverse-osmosis (RO) constant-pressure water purifier with heating function

Abstract

The invention relates to a water purifier with a heating function, particularly relates to a combined reverse-osmosis (RO) constant-pressure water purifier with a heating function, and aims at prolonging the service life of an RO membrane, increasing the water purifying efficiency, accurately mastering the replacing time of the RO membrane and effectively avoiding the problem that bacteria in purified water exceed the standard. In order to achieve the aims, the invention provides the technical scheme as follows: the combined RO constant-pressure water purifier with the heating function comprises a water pump, a filtering unit, an RO membrane treatment unit and a water storage barrel, wherein the filtering unit and the RO membrane treatment unit are sequentially connected with a water inlet pipe; the water storage barrel is connected with a purified water outlet pipe of the RO membrane treatment unit; a water inlet pipe of the RO membrane treatment unit is provided with an electromagnetic valve; a wastewater pipe of the RO membrane treatment unit is also connected with a water return pipe for returning wastewater to the water inlet end of the RO membrane treatment unit; and the end of the purified water outlet pipe is also connected with a heating tank. The combined RO constant-pressure water purifier with the heating function has the beneficial effects of prolonging the service life of the RO membrane, effectively inhibiting bacteria and reducing the energy consumption and wastewater yield.

Description

technical field [0001] The invention relates to a water purifier with heating, in particular to a combined reverse osmosis constant pressure water purifier with heating. Background technique [0002] The main problem existing in the current product is that the total number of colonies in the soaking test exceeds the standard. However, none of the existing reverse osmosis water purifiers has a filter element to kill the colonies, so that the total number of bacterial colonies will exceed the standard again when the water purified by the entire reverse osmosis water purifier enters the pressure tank, causing harm to human health. The RO reverse osmosis membrane of the reverse osmosis water purifier has a short service life, and there is no good control over the time to replace the RO reverse osmosis membrane, resulting in either not being replaced in time, or the RO reverse osmosis membrane being replaced before its service life, resulting in waste.

However, none of the existing reverse osmosis water purifiers has a filter element to kill the colonies, so that the total number of bacterial colonies will exceed the standard again when the water purified by the entire reverse osmosis water purifier enters the pressure tank, causing harm to human health. The RO reverse osmosis membrane of the reverse osmosis water purifier has a short service life, and the time for replacing the RO reverse osmosis membrane is not well controlled, resulting in either not being replaced in time, or the RO reverse osmosis membrane is replaced before the end of its service life, resulting in waste
