Description

The water-saving type toilet flush

The utility model relates to a kind of toilet flush, particularly a kind of water-saving type toilet flush.Washroom in its suitable public building, unit, private residence or any building uses.

Toilet flush present general washroom use or that sell on the market is single water hole, so have only a kind of quantitative discharging quantity of water, all is the same current of measuring regardless of washing just dirt of stool or water, opening drainage switch (spanner).As everyone knows, when flushing urine, water yield waste is more, and users feel regret, and wish that urgently with good grounds needs provide the product of different water supply volumes to come out early.Moreover source of clean water day is becoming tight in the world at present.Some northern cities of China particularly, clean short water supply, and since the toilet flush water the water waste that causes of science is more not troubling, 1 year 365 days, the water waste is countless, not only increase country, unit, resident's economy expenditure, and the pressure of water supply department increases day by day.More far-reaching serious problems are increasingly sharpening of causing the world the source has dried up.

The purpose of this utility model is intended to overcome the shortcoming of above-mentioned toilet flush, and existing toilet flush is made improvements slightly, provide a kind of can be according to the needs control water yield of flushing, the water-saving type toilet flush that dirt can be rinsed well.

The purpose of this utility model is to realize like this: comprise casing, water intaking valve, ball float, draining valve, drain elbow, drain elbow, drainage switch (spanner) is formed.Its bottom half has double water hole, and drain elbow is Height inequality suitable for reading that shape, this drain elbow put in casing has draining valve respectively, and casing has the drainage switch of controlling the draining valve switching motion respectively and linking to each other with draining valve outward.

Above-mentioned

The shape drain elbow puts in that co-altitude in the casing is suitable for reading to have draining valve respectively, has overflow plate between this two draining valve, and the overflow plate below has the hole, and the place has draining valve at the hole.

The single water hole that the utility model will have water box of water closet now changes double water hole into, and straight shape drain elbow is changed into

The shape drain elbow, set up several spare and accessory parts again, the water that can make flushing urine only is casing about 1/3 of the total amount that is filled with water, and can reach the purpose of conserve water, large and small just dirt can be washed again in only, spending and alleviate the pressure that government department supplies water effectively conserves water.The utility model is simple in structure, making is easy, with low cost, easy and simple to handle, economical and practical, benefit the nation and the people.

Embodiment one: with reference to seeing Fig. 1-Fig. 4 (" low level cistern 480 * 215 * 330mm with wall-hanging 12 ³Be example).Have an inlet opening 12 and two drain holes 11 (two holes 11 are at a distance of 160mm) in the bottom of casing 5, Shape drain elbow 6 puts in the casing 5 from hole 11; 6 liang of bend pipes are suitable for reading put in the casing 5 inequality apart from the height of its bottom surface, a high last open height is about 2/3rds (about 160mm) of casing 5 water height, low place, casing 5 bottoms, the height of bend pipe 6 draining valve (3,2) of installing respectively suitable for reading put suitable for reading; The water intaking valve 1 that is installed on the water inlet pipe 8 links to each other with ball float 4 through connecting rod 7, has two drainage switches (9,10) outside the casing 5, and drainage switch 9 links to each other with draining valve 2, and drainage switch 10 links to each other with draining valve 3.

It is DN50mm turnover plate type or straight valve (wherein: draining valve 3 can adopt brachymemma bleed off pipe 3/5 or block bleed off pipe fully, and the way of closing the envelope overflow mouth of pipe realizes the function of draining valve 3) that draining valve (2,3) is all selected inside nominal diameter for use.Water intaking valve 1 adopts the accessory of inside nominal diameter DN15mm, nominal pressure 0.6MPa; Ball float 4 is selected the accessory of φ 100mm specification for use; Low level cistern and high level cistern are selected L230mm and L280mm specification accessory respectively for use; Bend pipe 6 is selected the pipe of inside nominal diameter DN50mm for use; Casing 5 can comprise a case lid; The installation of each accessory, connected mode are the known technology of existing toilet flush.

Embodiment two: referring to Fig. 5-Fig. 8. Shape bend pipe 6 puts in the casing 5, the height of putting its place, bottom is identical, 6 liang of draining valves (2,3) of installing respectively suitable for reading of bend pipe, on casing 5 bottoms between this draining valve (2,3) overflow plate 14 is installed, overflow plate 14 belows have hole 15, draining valve 13 (two holes 11 are at a distance of 220mm, and the height of overflow plate 14 on casing 5 is 200mm, and overflow plate 14 is 160mm apart from casing 5 right walls) is installed at 15 places, hole.Other structure is with embodiment one.The specification of draining valve 13 is identical with draining valve (2,3).

The course of work of the present utility model is as follows:

Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, embodiment 1: by limiting the water level storage of water, ball float 4 floats on the surface in the casing 5, when needing flushing urine, move switch 10, draining valve 3 is opened, apart from the water more than the casing 5 bottom surface 160mm height, by the higher side inflow sewer pipe suitable for reading of bend pipe 6, after washing down urine, draining valve 3 cuts out automatically, and ball float 4 descends, this moment, water intaking valve 1 was opened automatically, and the water intaking valve 1 of clean water (introducing from running water pipe) through bringing water pipe 8 into fills in the casing 5 to constrain height.When needing the flushing stool, move switch 9, draining valve 2 is opened, whole waters in the casing 5 are washed down greatly after an action of the bowels by the lower side inflow sewer pipe suitable for reading of bend pipe 6, and draining valve 2 cuts out automatically, ball float 4 descends, and this moment, water intaking valve 1 was opened automatically, and clean water fills in the casing 5 to constrain height.So go round and begin again.

Referring to Fig. 5, Fig. 6, Fig. 7, Fig. 8, embodiment 2: by limiting the water level storage of water, ball float 4 floats on the surface in the casing 5, when needing flushing urine, move switch 10, draining valve 3 is opened, the water on overflow plate 14 right sides washes down urine by bend pipe 6 inflow sewer pipes suitable for reading.At this moment, because the effect of overflow plate 14 left side water pressures, the hole 15 of overflow plate 14 belows is covered by draining valve 13, only the water on overflow plate 14 right sides flows into sewer pipe, and the water in overflow plate 14 left sides is not arranged down, ball float 4 declines this moment, and draining valve 3 cuts out, water intaking valve 1 is opened automatically, and the space on overflow plate 14 right sides is to constrain height in the full casing 5 of clean water.When needing the flushing stool, move switch 9, draining valve 2 is opened, the water in overflow plate 14 left sides is all by the inflow sewer pipe suitable for reading in bend pipe 6 left sides, this moment is because the effect of overflow plate 14 right side water pressures, the draining valve 13 at 15 places, hole, overflow plate 14 below is opened automatically, and the water on overflow plate 14 right sides flows into overflow plate 14 left sides by hole 15 to be continued to wash down stool by suitable for reading whole inflow sewer pipes in bend pipe 6 left sides.Draining valve 2, draining valve 3, draining valve 13 all are in closed condition at this moment, and ball float 4 descends, and water intaking valve 1 is opened automatically, and in the full casing 5 of clean water, overflow plate 14 and arranged on left and right sides are to constrain height.So go round and begin again.
