Abstract

The utility model relates to a simple-structure particularly water-saving closet comprising a urinal, a washing water channel, a flooding nozzle, a siphon tube and a floating ball. The utility model is characterized in that the flooding nozzle has a section in a back taper shape; a dome of the siphon tube is not higher than the lower edge of a sewage outlet of the urinal; the floating ball is arranged on the dome of the siphon tube. The siphon tube is provided with the lower dome, so washing process only aims to dash objects in the urinal out of the sewage outlet in a water-saving way. The energy storage effect of the floating ball enhances siphonage force to suck the objects in the urinal more cleanly also in the water-saving way.

Description

Water-saving closet

The utility model relates to a kind of water-saving closet, and especially a kind of structure is simpler, the significant especially water-saving closet of water-saving result.

The closet that uses is realized the Odour seal function with syphon at present, and satisfying the syphon condition of work is to have enough liquid measures to come through the syphon dome moment, produces negative pressure when it is fallen the exhaustion of urinal content is discharged.For guaranteeing that enough liquid measures are arranged, be provided with upper water box and water-supply apparatus, according to domestic different brands closet is investigated, each washing water quantity is all greater than 10 liters, and the chamber pot flushing water amount of economizing on water most is also more than 6 liters in the world.

The purpose of this utility model provides a kind of without upper water box and water-supply apparatus, and the water-saving closet of special water saving.

The purpose of this utility model is to realize like this, water-saving closet is integrated, the built-in flushing water passage in urinal upper edge, the passage downside is the flushing nozzle of inverted cone shape along urinal inner wall even distribution section, and the preposition blow-off pipe of urinal sewage draining exit and syphon is a three-port structure, and annular nozzle is established at the blow-off pipe top, the syphon dome is not higher than urinal sewage draining exit lower edge, the ball float of a proportion less than air placed by vault portion, and syphon pipe tail is reserved the float chamber, is outlet opening before the chamber.Going into the lavatory finishes, breakdown flow Self controlling valve, rinse water is washed away urinal inwall and blowdown tube wall through flushing nozzle and annular nozzle, the urinal content is rushed in the blow-off pipe, under the acting in conjunction of freely falling body acceleration of gravity and annular flushing water, guaranteed that moment has enough liquid measures to come through syphon vault portion, satisfied the basic operating conditions of siphon principle, produced siphonage.The effect of ball float is to guarantee and strengthen siphon effect, when the urinal content is rushed to dome, run into the retardance of ball float, speed must subtract casual, follow-up cleaning fluid and but continue to gush next, cause the potential energy savings, this moment, fluid column was in the summit, and the acting in conjunction of potential energy and potential energy makes fluid column drop sooner, and the siphon power of generation is stronger, ball float is rushed in the float chamber under the promotion of fluid column, the urinal content then flows to sewer pipe through outlet opening.After the dirt emptying, the buoyancy of ball float is self rising to siphonal vault portion.

Owing to adopt technique scheme, cancellation upper water box and water-supply apparatus under the prerequisite that guarantees siphon power.The accumulation of energy effect of ball float is magical, and is particularly less at the feed pipe bore, and under the inadequate slightly situation of moment discharging quantity of water, its effect is more obvious, according to test, is 25mm at the upper hose diameter, supplies water to press to be 5Kg/cm ²Condition under, simulating stool wash water amount is 2.4 liters, urine is 1.2 liters; At the upper hose diameter is 15mm, supplies water to press to be 5Kg/cm ²Condition under, simulating stool wash water amount is 2.8 liters, urine is 1.5 liters; Owing to cancelled upper water box and water-supply apparatus, product cost can reduce more than 40%; If the use water closet, the transverse tube of logical sewer can not penetrate floor and install, and straight-through water vertical tube had down both reduced the seepage chance in this floor plate, also can not influence the complete, attractive in appearance of lower floor's ceiling.

Below in conjunction with the embodiment accompanying drawing, the utility model is described in further detail.

Fig. 1 is the water-saving closet generalized section

Fig. 2 is that the syphon boundling is arranged schematic diagram

Fig. 3 is that the syphon axis launches schematic diagram

Among the figure: 1. flow Self controlling valve, 2. flushing water passage, 3. flushing nozzle, 4. urinal, 5. annular nozzle, 6. blow-off pipe, 7. ball float, 8. float chamber, 9. outlet opening.

In Fig. 1, closet is integrated, urinal (4) the ring built-in flushing water passage in upper edge (2), and suitable inner wall even distribution section is the flushing nozzle (3) of inverted cone shape, urinal sewage draining exit and blow-off pipe (6) are three-port structure, and annular nozzle (5) is located at the top of blow-off pipe (6), and the ball float (7) of a proportion less than air put in syphon vault portion, syphon pipe tail is reserved float chamber (8), is outlet opening (9) before the chamber.Breakdown flow Self controlling valve (1), water is washed away urinal (4) inwall and blow-off pipe (6) inwall by rinse water passage (2) through flushing nozzle (3) and annular nozzle (5), the urinal content is rushed in the blow-off pipe (6), under the acting in conjunction of freely falling body acceleration of gravity and annular flushing waterpower, guaranteed that moment has enough liquid measures to come through syphon vault portion, satisfy siphonal condition of work, the effect of ball float (7) is to guarantee and strengthen siphon effect, when the urinal content is rushed to dome, the retardance that runs into ball float (7) is slowed down, follow-up washing lotion but gushes in a steady stream, cause potential energy to accumulate, because of liquid level is in highest order, the outburst of potential energy and potential energy makes the speed of fluid column drop faster, and the siphon power of generation is more powerful, ball float is under the promotion of fluid column, rush in float chamber (8), the urinal content then enters sewer pipe through outlet opening (9) in an orderly manner, and clear water is stayed syphon bottom and play and prevent that sewer waste gas from overflowing effect.After the dirt emptying, ball float (7) floats back dome voluntarily.

Claims (3)

1. water-saving closet, it comprises urinal, the rinse water passage, flushing nozzle, annular nozzle, blow-off pipe, syphon and ball float team is characterized in that: flushing nozzle section is an inverted cone shape, and a circular nozzle is established at the blow-off pipe top, the syphon dome is not higher than urinal sewage draining exit lower edge, and an agglomerate tabling ball is placed by syphon vault portion.

2. water-saving closet according to claim 1, its feature also is: water-saving closet can be water closet, also can be pan.

3. water-saving closet according to claim 1, its feature also is: the urinal sewage draining exit is that 90 ° of threeways are connected with blow-off pipe.
