Water purifier waste water quantity regulating device
Technical field
The invention belongs to water filtration field of purification, be specifically related to a kind of water purifier waste water quantity regulating device.
Background technology
Water purifier adopts the filter element of filtering material composition, makes former water via filter element filtering, filters out impurities, becomes pure water after harmful substance, for directly or heating drink, remaining partial raw water becomes " waste water " after filtering. Producing waste water in filtration, prior art is to be expelled directly out or be temporarily contained in waste water tank and finally discard by being commonly called as the proportioning valve of " waste water ratio "; Generally being provided with raw water box and pure water tank on machine, the former holds former water to be filtered, and the latter is then used for the pure water after holding filtration; It is defecator between raw water box and pure water tank, is connected each other by sealing waterway. Traditional is technical, and the ratio of pure water and waste water is up to 1:3, and the waste ratio of water resource is more serious, and the what is called " waste water " under this situation, but be that impurity concentration is higher than former water.
For overcoming the too much defect of waste water, topple over the loaded down with trivial details of waste water also for reducing, prior art provides a kind of technical scheme: by the return of waste water after filtering to raw water box, again or repeatedly circulating filtration, reach water saving and effect more convenient to operate. But, the former water impurity concentration owing to being mixed with waste water is progressively higher than former water, and its handling capacity in filtration system can reduce, and its negative effect is reduction of filter efficiency, shortens the life-span of filter element. This is also why waste water can not be utilized completely, and always has a certain proportion of reason, and under certain critical state, the too high waste water of impurity concentration is again introduced into filtration system and is just difficult to technically, and very uneconomical.
It addition, prior art there is also following defect: the final volume holding waste water i.e. wastewater flow rate are changeless. Due in different regions, the water quality difference at different water source substantially, the waste water ratio weighed from technical standpoint economic angle there is also very big-difference; Owing to the situations such as the consciousness of saving water of consumer, waste water purposes, intended filter efficiency are different, it wants to regulate voluntarily, independently judge wastewater flow rate.

Described raw water box is respectively equipped with effluent switch and water inlet switch with main line and reflux pipe joint;
Described effluent switch and water inlet switch are check valve-type structure, and wherein the parts of spool offside are provided with top, when raw water box connects with main line and reflux pipe, spool can be backed down by top, making pipeline turn on, when raw water box lifts, spool is closed under spring force effect;
Main line between described raw water box and defecator is provided with booster pump;
Described pure water tank and main line joint are provided with pure water tank water inlet switch;
Case mouth place, described pure water tank upper end is provided with water level control head.
The method have technical effect that: can arbitrarily regulate tapping pipe open height according to different situations, independently determine waste water ratio, reach the water-saving result of the best; It addition, the Inlet and outlet water switch that the present invention is arranged, raw water box is facilitated to separate with machine body, in order to add water and topple over waste water, it is to avoid leaking.

Detailed description of the invention
Following embodiment is to further illustrate using as the explaination to the technology of the present invention content for present invention; but the flesh and blood of the present invention is not limited in described in following embodiment, those of ordinary skill in the art and can should know any simple change based on true spirit or replacement all should belong to protection domain of the presently claimed invention.
As shown in Figure 1, a kind of water purifier waste water quantity regulating device, including raw water box 10 and pure water tank 20, connected by main line 11 between described raw water box 10 and pure water tank 20, described main line 11 is provided with defecator 30, the wastewater outlet of defecator 30 is linked back raw water box 10 further through a reflux pipe 12, it is characterized in that: in described raw water box 10, be provided with a tapping pipe 13, described tapping pipe 13 is vertical to be arranged on bottom raw water box 10, tapping pipe 13 upper end is uncovered, with raw water box 10 inner space, tapping pipe 13 lower end connects with main line 11, the height adjustable of described tapping pipe 13.
The space maximum height being used for holding water in raw water box 10 is H, and the height that tapping pipe 13 is minimum is h1, it is recommended that h1 is 1/4H, and namely minimum waste water ratio is 25%. Tapping pipe 13 should be less than H by regulating the maximum height that can reach. For telescoping tube regulative mode, when tapping pipe 13 mouth of pipe is in lowest order, run Pure-water Making, after one end cycle, the mixing water being in below discharge opening in raw water box 10 will, as waste water, be that water-saving result is best under this state, and the impurity content of waste water is also the highest. If by visual or test, user thinks that the water quality of this effluent part is too poor to such an extent as to cannot recycle and can only thoroughly discard, but he can use the water of poor water quality to do the wash, rush toilet etc. just, telescoping tube just can be pulled out by he, raise discharge opening height, remaining waste water after a same circulation, although impurity concentration is higher, cannot be used for drinking or cooking, but can be used to mop floor, rush toilet etc., will not go out of use; By that analogy, it is also possible to continue to raise discharge opening so that final waste water impurity concentration reduces further, it is used for washing the occasion such as dish, laundry.
