Abstract
The utility model relates to a water-temperature-regulation-type reverse osmosis water purifier which comprises a reverse osmosis water treatment system. The reverse osmosis water treatment system orderly comprises a water inlet, a pretreatment component, a reverse osmosis membrane, a purified water outlet and a concentrated water outlet. The water-temperature-regulation-type reverse osmosis water purifier is characterized in that a heating body is connected in any position between the water inlet and reverse osmosis membrane of the reverse osmosis water treatment system. The water-temperature-regulation-type reverse osmosis water purifier has the advantages that as the heating body is connected in a position before the reverse osmosis membrane of the reverse osmosis water treatment system and used for regulating the water temperature, the inlet water temperature can be controlled below the upper limit of the allowable working temperatures of the reverse osmosis membrane, and therefore, the function of increasing the water yield flux of the reverse osmosis membrane is realized, the defects of extra low purified water yield and too much concentrated water drainage of the existing reverse osmosis water purifier in microthermal climate are overcome, and in the meantime, the temperature of the purified water is increased so that the purified water becomes warm water suitable for the human to directly drink.
Description
Technical field
The utility model relates to water-purifying machine, and particularly a kind of water temperature adjustment type reverse osmosis water purifier, belongs to the technological improvement of existing reverse osmosis water purifier.
Background technology
The current raising along with people's living standard, the cleanliness factor of tap water is required also to improve constantly, and water pollutes constantly aggravation, water-purifying machine progressively enters ordinary citizen's family, wherein reverse osmosis water purifier is as the highest product of a kind of filtering precision, because of its water purification effective, moderate cost, the parent who is subject to users looks at, and reverse osmosis water purifier has become the first-selection of safty of drinking water.But because the kernel component of reverse osmosis water purifier is reverse osmosis membrane (hereinafter to be referred as RO film), the purification water yield of RO film output (being water production rate) is closely related with water temperature, the technical manual that AnRO film manufacturer provides, 3 ℃ of the every reductions of inflow temperature, RO film water production rate can reduce approximately 10%.
Fig. 1 is a kind of current existing reverse osmosis water purifier, as shown in the figure, during its work, tap water direct taps into into the first preprocessing filter element 1 and processes, and after topping-up pump 2 superchargings, then through the second preprocessing filter element 3 and the 3rd preprocessing filter element 4, processes successively, then through large flux reverse osmosis membrane 5, further filter, after filtration, become two-way: a road just becomes pure water after filtration through rearmounted filter core, capable of direct drinking; Another road is condensed water and discharges through waste water combination valve 7.Obviously, its inflow temperature of this reverse osmosis water purifier depends on the tap water water temperature of entrance completely, depend on envrionment temperature completely, uncontrollable, this just caused in high summer of temperature and temperature low winter, machine water production rate difference is huge, and the water production rate under 5 ℃ of inflow temperatures only has 40% left and right of water production rate under 30 ℃ of inflow temperatures.As at northern area, Xia Dongwen is poor larger, and the problem of this water production rate difference is more outstanding.In addition,, due to the RO film front and back end water yield (flooding quantity=water production rate+dense water yield) in a basic balance, water production rate declines and must cause the dense water yield to increase, and causes the waste of water resources.
Meanwhile, in low temperature season, the leaving water temperature(LWT) of conventional reverse osmosis water-purifying machine is equally low with inflow temperature, is not suitable for directly drinking, and the rear of need heating is separately drinkable, to user, makes troubles.
Summary of the invention
The purpose of this utility model is to provide a kind of water temperature adjustment type reverse osmosis water purifier, to overcome prior art in the high problem of low, the dense water of low temperature season water production rate; Meanwhile, solve the too low problem that cannot directly drink of low temperature season water temperature.
The technical scheme that realizes the utility model object is, a kind of water temperature adjustment type reverse osmosis water purifier, comprise reverse osmosis water treatment system, described reverse osmosis water treatment system comprises water inlet, pretreatment component, reverse osmosis membrane, pure water outlet and condensed water outlet successively, it is characterized in that, at the water inlet of described reverse osmosis water treatment system, to the optional position between reverse osmosis membrane, be connected with heating member.
Above-mentioned pretreatment component comprises the first preprocessing filter element, the second preprocessing filter element and the 3rd preprocessing filter element being cascaded, and between the first described preprocessing filter element and the second preprocessing filter element, is also provided with magnetic valve and topping-up pump.
Above-mentioned heating member is connected between the water inlet and pretreatment component of reverse osmosis water treatment system.
Above-mentioned heating member is connected between the different pretreatment component of reverse osmosis water treatment system.
Above-mentioned heating member is connected between described pretreatment component and reverse osmosis membrane.
Above-mentioned heating member is automatic heating device, includes temperature setting device, temperature sensing device and heating unit.
The beneficial effects of the utility model are, because the position before the reverse osmosis membrane of reverse osmosis water treatment system is connected with heating member, water temperature is regulated, therefore, inflow temperature can be controlled to the upper limit that reverse osmosis membrane allows working temperature, thereby realize the function that increases reverse osmosis membrane permeant flux, overcome that existing reverse osmosis water purifier purifying aquatic product water yield under microthermal climate is too low, condensed water is discharged too much drawback, and simultaneously by the temperature increase of purifying waste water to the warm water that is applicable to human body and directly drinks.
