Description

The maintenance-free domestic water activating machine

Technical field

The utility model relates to the Domestic living machine, belongs to the water purifying plant technical field.

Background technology

The RO reverse osmosis technology is state-of-the-art water technology in the world at present, reverse osmosis method is recovered as pure water for the astronaut by urine the earliest and uses, whole principle of work all adopts Physical, do not add any sterilant and chemical substance, so chemical phase transformation can not occur, and reverse osmosis membrane is separate dissolved oxygen not, so produce by this method the pure water drawn, be running water, drink sweet good to eat.Reverse osmosis water purification machine enters Chinese market existing more than 20 year; but not a large amount of universal all the time; major cause is exactly the fatal weakness that is designed with of current this domestic water purifying machine: be generally Pyatyi and filter; first step PP cotton; second stage granulated active carbon; the 3rd utmost point PP cotton or extruded activated carbon, fourth stage RO reverse osmosis membrane, level V post active carbon.Tap water, after front three-stage filtration, then passes through the high-pressure pump supercharging, pure water out after the RO reverse osmosis membrane, and the impurity that can't pass through is discharged through the waste water mouth.Such design is to hold back the large particulate matters such as lower a large amount of silt, iron rust with the PP cotton, with chlorine residue in charcoal absorption water, the RO reverse osmosis membrane is played to a provide protection.This design requirements PP is cotton must be changed once in 3-6 month, if water quality is bad, replacement frequency can be higher, otherwise too many through the impurity before the PP cotton, will form new source of pollution, pollutes conversely tap water.And most of user do not know this principle, the commission merchant, for cost-saving, also can initiatively not go to change the PP cotton to the user, causes water-purifying machine with after for some time, and water has strange taste, or causes the water machine not long work-ing life.Even if can change in time the PP cotton, also can bring very high use cost to the user.So just be badly in need of the equipment that a kind of granule foreigns such as silt that the PP cotton can be retained down are removed in time.

Summary of the invention

The purpose of this utility model is to solve the weak point that above-mentioned prior art exists, provide a kind of reasonable in design, in time removal of contamination, without the frequent maintenance-free domestic water activating machine of renew cartridge, the use cost that has reduced the user, longer service life more.

The utility model is achieved through the following technical solutions:

The maintenance-free domestic water activating machine, its special character is to comprise inner pressed central ultra-filtering water purifier 2, inner pressed central ultra-filtering water purifier 2 two ends are respectively equipped with water-in 1 and sewage draining exit 16, sewage draining exit 16 is connected with domestic water tap 15, inner pressed central ultra-filtering water purifier 2 right-hand members are equipped with water outlet 3, water outlet 3 is connected with the low-tension switch 4 on the reverse osmosis main frame, the reverse osmosis main frame comprises the low-tension switch 4 connected successively, magnetic valve 5, granulated active carbon filter core 6, topping-up pump 7 and reverse osmosis membrane 8, reverse osmosis membrane 8 tail ends are provided with the first distributive pipe 17 and the second distributive pipe 18, the first distributive pipe 17 is connected with threeway 12 by high-voltage switch gear 11, threeway 12 1 ends are connected with pure water water tap 14, threeway 12 the other ends are connected with pressure pot 13, the second distributive pipe 18 is connected with waste water proportional valve 10, waste water proportional valve 10 is connected with waste water mouth 9.

Maintenance-free domestic water activating machine of the present utility model, adopt the fore filter of inner pressed central ultra-filtering water purifier as whole water activating machine, compare the PP cotton, filtering accuracy is higher, can effectively extend the work-ing life of reverse osmosis membrane, the impurity be trapped on inner pressed central ultra-filtering water purifier also can be removed it by using domestic water, constantly to guarantee the clean, pure and fresh of former water, simultaneously in 3-5 also without renew cartridge more, greatly reduce user's use cost, also to the dealer, brought convenience, and volume is less, has saved space.

Embodiment

Provide embodiment of the present utility model below with reference to accompanying drawing, be used for formation of the present utility model is described in further detail.

The maintenance-free domestic water activating machine of the present embodiment, comprise inner pressed central ultra-filtering water purifier 2, inner pressed central ultra-filtering water purifier 2 two ends are respectively equipped with water-in 1 and sewage draining exit 16, sewage draining exit 16 is connected with domestic water tap 15, inner pressed central ultra-filtering water purifier 2 right-hand members are equipped with water outlet 3, water outlet 3 is connected with the low-tension switch 4 on the reverse osmosis main frame, the reverse osmosis main frame comprises the low-tension switch 4 connected successively, magnetic valve 5, granulated active carbon filter core 6, topping-up pump 7 and reverse osmosis membrane 8, reverse osmosis membrane 8 tail ends are provided with the first distributive pipe 17 and the second distributive pipe 18, the first distributive pipe 17 is connected with threeway 12 by high-voltage switch gear 11, threeway 12 1 ends are connected with pure water water tap 14, threeway 12 the other ends are connected with pressure pot 13, the second distributive pipe 18 is connected with waste water proportional valve 10, waste water proportional valve 10 is connected with waste water mouth 9.

Installation process: by the water-in of the water-in of tap water and inner pressed central ultra-filtering water purifier with hose connection, the flexible pipe that connects domestic water in kitchen is connected with the sewage draining exit of inner pressed central ultra-filtering water purifier, the water outlet of inner pressed central ultra-filtering water purifier is connected with the reverse osmosis main frame again.

Principle of work: the water outlet of inner pressed central ultra-filtering water purifier forms two kinds of water after low-tension switch (often opening), granulated active carbon filter core, topping-up pump, reverse osmosis membrane; a kind of is pure water; pure water enters respectively pure water water tap and pressure pot after high-voltage switch gear (normal closing), threeway; another kind is waste water, and waste water is connected to floor drain through waste water proportional valve, waste water mouth.

When tap water has pressure (water is arranged), low-tension switch is opened, and high-voltage switch gear is normally closed, and magnetic valve is opened, and topping-up pump energising work, start water processed;

When the pure water pressure pot reaches certain pressure (water is full), the high-voltage switch gear breaking circuits, closed electromagnetic valve, topping-up pump quits work, and water processed stops;

When water, hydraulic pressure descends, the high-voltage switch gear circuit that closes, and magnetic valve is opened, and topping-up pump energising work starts again water processed, and when water is full, the high-voltage switch gear breaking circuits, quit work, with this reciprocation cycle;

When lack of water, low-tension switch can cut off the power supply, and quits work.

The unspecified content of the utility model is prior art, and those skilled in the art can obtain inspiration from the present embodiment and prior art, are out of shape and obtain other embodiment.Therefore, protection domain of the present utility model should be determined according to the protection domain of claim.
