Water-saving type RO purifier

Abstract

A water-saving reverse-osmosis water purifying machine comprises a machine case and a membrane filtration device for reverse-osmosis treatment of water comprising a booster pump inside the machine case, a reverse-osmosis membrane filtration assembly, a pressure-resistance purified water storage bucket, pipelines, joints, valves, and a control circuit, which is characterized in that inside the machine case is arranged a mixing water storage tank, and the impurity-containing water outlet of the reverse-osmosis membrane filtration assembly is connected with the mixing water-storage tank via a pipeline; the water pipe to be treated which is jointed with the water inlet joint on the machine case is divided into two branched pipes, wherein, the first branched pipe is connected to the inlet of the booster pump via the mixing water-storage tank, and the second branched pipe meets with the impurity-containing water from the mixing water-storage tank and then is connected to the non-purified water outlet of the machine case. In the invention, the impurity-containing water treated by reverse-osmosis membrane can be efficiently reclaimed and reused, thereby preventing wasting of water resource, simultaneously, prolonging the service life of membrane, and improving economic benefit. Additionally, the invention is provided with reasonable structure.

Description

technical field [0001] The invention relates to a drinking water machine which uses a reverse osmosis membrane to treat water. Background technique [0002] With the continuous advancement of science and technology and the seriousness of industrial pollution, many water sources have been destroyed, and the shortage of international and domestic water resources is very serious. Although the water plants in the city treat the water and turn it into tap water for supply to everyone, the water quality is still poor. Not a good guarantee, on the contrary, people's living standards continue to improve, and higher requirements have been put forward for water quality. Therefore, people have developed various water dispensers, such as the Chinese patent "a full-cycle direct drinking water dispenser" of 00420088581.0 , it includes a chassis, the outer surface of the chassis is provided with an electrical control panel, and it is characterized in that: the chassis is equipped with a mu...

[0002] With the continuous advancement of science and technology and the seriousness of industrial pollution, many water sources have been destroyed, and the shortage of international and domestic water resources is very serious. Although the water plants in the city treat the water and turn it into tap water for supply to everyone, the water quality is still poor. Not a good guarantee, on the contrary, people's living standards continue to improve, and higher requirements have been put forward for water quality. Therefore, people have developed various water dispensers, such as the Chinese patent "a full-cycle direct drinking water dispenser" of 00420088581.0 , it includes a chassis, the outer surface of the chassis is provided with an electrical control panel, and it is characterized in that: the chassis is equipped with a multifunctional pure water device, a circulating water pump, an ultraviolet sterilizer, an R.O reverse osmosis membrane ultrafilter, and a post activated carbon filter And the automatic heater, the bottom of the multifunctional water purifier is connected with the tap water pipe, the top is connected with the inlet of the circulating water pump through the pipeline, the outlet of the circulating water pump is connected with the ultraviolet sterilizer, and the ultraviolet sterilizer is connected with the R.O reverse osmosis membrane through the pipeline The ultrafilter is connected, the R.O reverse osmosis membrane ultrafilter is connected with the rear activated carbon filter through a pipeline, the outlet of the rear activated carbon filter is through a pipe tee branch, one end is connected to the water inlet of the three-way special cold water valve, and the other end is After connecting the automatic heater, it is connected to the hot water valve. The tap water is processed by the innovative "six times of filtration + sterilization + circulation", which can be repeatedly purified and sterilized, and can provide truly pure and sterile direct drinking water at any time. The structural defect is that The impurity-containing water after the R.O reverse osmosis membrane ultrafilter is impure water that has not been well recycled and directly discharged, resulting in waste of water resources. These shortcomings are also a large number of traditional water treatment devices that use reverse osmosis membranes. existing

For example, the Chinese patent No. 200520083442.3 "concentrated water reuse equipment for water treatment system reverse osmosis device" recycles and treats wastewater. However, this structure can be used in devices with relatively large processing capacity. The water treatment device cannot be used directly, otherwise the cost will increase and the volume will increase, so a new improved design is required
