Description

Flat draining valve

Technical field

The present invention relates to a kind of sanitary equipment valve, particularly relate to a kind of sealing plate that is applicable to use in ultra-thin water tank and seal and be non-circular flat draining valve.

Background technology

Toilet has had more than 500 year history so far from Britain's invention, and the structure of all kinds of hydrocone types is shaped.Now, we are water-saving type closestool by siphonage-toilet seen on market, can realize 4.2 liters of floats, arrange the market access requirements of 6 liters greatly, but will realize the country-level water saving standard that country appraises and decides recently, owing to being subject to toilet structure aspect, have got long long way to go.

How could guarantee scientifically water saving under the prerequisite of rinsing well, this is a very large also very abstruse problem.

Judge the quality of a toilet performance, core index will say to only have two, is exactly washing force and replacement ratio.As for the examination criteria of water consumption, also have in my view many needs perfect place, be mainly method and the canonical parameter that the size issue country of washing force there is no detection so far.At present, the method that effect is scrubbed in legal detection is to brush some red water in bedpan surrounding, even if having water flow to red waterborne scrub qualified.This scrubs the vicious circle of effect with regard to having caused present product to think little of.

The washing force of toilet is too little, is bonded at ight soil on bedpan and can't is washed off, and this is that ordinary person can not turn a blind eye to.The countermeasure of taking is generally repeatedly to rinse, and just can use brush instead and remove brush in the situation of last resort, has brushed or will rinse, and both time-consuming, effort, went back water wasting.If washing force is large, the situation that punching is not fallen can be lacked a lot.

Mention here, just two problems have been proposed: the one, why is washing force little for present toilet? the 2nd, there is what way to solve the little problem of washing force? we know, the flow passage system of toilet mainly by water tank, aqueduct, water guide circle, scrub hole, injection pipe, spray-hole, blow-off pipe and form.Before use, aqueduct, water guide circle and injection pipe are all empty, and this three's empty volume just has 3 liters more than nearly.When people bring into use, scrubbing hole and spray-hole is to have water to flow.Approximately 30 3-4 millimeters are thick scrubs hole and 1 diameter has 30 millimeters of thick spray-holes when flowing water, also will fill that empty volume of 3 liters nearly, do not have 5 liters of above water yields be impossible this flow passage system is filled and by the level pressure in water tank be transmitted to scrub with spray-hole on.But the water consumption of toilet can not surpass 6 premium on currency, even if also take advantage of 1 premium on currency to have pressure, the water level of this 1 premium on currency is very low, pressure is also just very little.So on present market, all toilets are all far from being any washing force, can only say that water flows through.

For solving the hypodynamic problem of scrubbing, as far back as 2007 I just declared the patent of invention of pressure-guiding bedpan by name, utilize pressure in the pilot principle of water and closed container not have directive principle, the water level potential energy of water tank is converted as much as possible to the kinetic energy that strengthens washing force and displacement.On May 13rd, 2009, State Intellectual Property Office has issued the certificate of 200710143460.X to me, and I have just carried out large-scale production in the Heng Jie in Foshan bathroom factory immediately.This invention has been played good effect for reducing water guide circle to hydraulic pressure energy release And Spread of Solute, toilet only with more than 3 liters, squat just only with just reaching national examination criteria more than 4 liters, and scouring force is large 2-3 doubly, I like the television ten platform < < of central authorities to invent > > and once twice this invention had been carried out to thematic broadcasting, have obtained many favorable comments of industry specialists and customer.

But, it has been obviously extremely difficult on the popular frame mode of existing siphonic closet, wanting further to strengthen washing force and replacement ratio on the basis at pressure-guiding bedpan again, because all siphonic closets all syphon are arranged on after bedpan, are water tank on it.That is to say with water guide circle and water tank between always want one section of very thick aqueduct to be communicated with.If do not adopt pressure-guiding bedpan principle, fill up this section of aqueduct and will consume water more than 1 liter; Both having made is to have adopted pressure-guiding bedpan principle, also wants the 200-300 milliliter water yield it could be filled up.The reason that causes this problem to exist has following two aspects: the one, syphon be arranged on bedpan mold developing is more convenient below, it is also more reasonable in structure, slightly to seem, establishes above below water tank and establishes syphon, space is waste not; The 2nd, before pressure-guiding bedpan comes out, people do not pay attention in toilet flow passage system those sky volumes for the releasable drawback of hydraulic pressure gesture, the design because global siphonic closet is not always the case.In addition, siphonal design sweep is too anxious, also takes up space very much.For addressing this problem, I have designed and a kind of syphon is around shape and is arranged on bedpan bottom, make syphon more smooth and easy, particularly from configuration aspects, set about optimizing the design of injection pipe, the decay of the potential energy that shortened injection pipe length, reduce cavity volume in flow passage system, reduces cistern water level in conductive process, thereby improve the straight spray ring of washing force and replacement ratio around the exquisite toilet of siphon, received good effect.

Through experiment, this straight spray ring is around the exquisite toilet of siphon, if the water height design of water tank is equally high to squatting pan cistern, the liftoff height controlled in the custom of this people below 1 meter of button namely, the washing force of bedpan will be than the washing force of our daily toilet large 3 times more than, and as long as 3 premium on currency just can reach national examination criteria completely.

Problem is on market, not have above-mentioned water tank to be equipped with.

By present ceramic process level, the general height of water tank is in 300 millimeter.If increase, technology difficulty is large, cost up again, and packed and transported cost is also constantly made friends with.Moreover, burnt till exactly tall and big ceramic water tank, on the panel of this exquisite toilet, do not have so large room to install yet.

Abroad, have a kind of down to enter formula water tank, its waterbox design water level is higher, and the squatting pan cistern difference in height of usually using compared with us is few.But because it is for the suspension type type toilet designs that directly falls, must support with a metal edges frame weight of toilet and human body, thus very heavy, and also accessory is very complicated, price is very expensive.

If adopt domestic wall-hanging squatting pan cistern, although cost very cheap, install very conveniently, exposed water tank and cleaning hose are too simple and crude again, do not embody the class of house fitting-up.If water tank down is entered within the walls, both destroyed the whole finishing of household, appearance is modified also difficult coordination, and engineering quantity is too large again.

Here, also have an important technology background also to need explanation: the water tank thickness of all sanitary equipment in the whole world is all more than 14 centimeters, reason is that bore that outfall must be larger could meet the requirement that sanitary equipment moments supplies water.And all draining valve valve blocks are all circular design, only have circular airtight sealing stressed the most balanced.So, no matter be ceramic water tank or plastic cistern, because be subject to the limitation of circular seal mouth size, its thickness is absolutely not to be done very thinly.

Have no idea to allow water tank do very thinly, thus realize water level highly put, easy for installation, elegant in appearance and dwindle taking up room of water tank? so I have had again new idea.

Summary of the invention

The present invention relates to a kind of sanitary equipment valve, particularly relate to a kind of sealing plate that is applicable to use in ultra-thin water tank and seal and be non-circular flat draining valve.

Above-mentioned technical problem of the present invention is by providing a kind of flat draining valve of following structure to solve, it comprises: valve body, float key, arrange that key, drive link, large row block, arrange greatly float, to arrange peg, main shaft, valve base plate, diaphragm seal, seal, outfall, float peg, float float, float greatly upper greatly, it is characterized in that: described sealing plate and seal are and are non-circular flat structure.

We know, what on market, be on sale throughout now is nearly all integral body or split toilet, and water tank is all exposed on toilet, and it not only accounts for toilet space, and is subject to the restriction of technology difficulty, can not do so highly with wall-mounted water tank.From hydrodynamics, the size of kinetic energy is directly proportional to the height of potential energy.So, the water tank that height is put is for scrubbing and replace very large effect.Although wall-mounted water tank can meet the high requirement of putting of water tank, exposed water tank and cleaning hose are too simple and crude again, if it is hidden in, engineering quantity is large within the walls, and bad outer decoration.It is too complicated again that the down of import enters formula water tank, and its price is surprisingly high.

Straight spray ring is around the design of the exquisite toilet of siphon, and essence needs hardly larger area below blow-off pipe has been displaced at the bottom of bedpan except lavatory lid.If adopt sealing plate and seal to be the water key that is non-circular flat structure, will with do a very thin water tank be arranged on cover plate after, for straight spray ring, around the realization of the exquisite toilet various functions of siphon advantage, having created may.

The flat draining valve of the present invention compare with the existing draining valve in market a maximum advantage be exactly for produce and the water tank of Bao Yougao created may.The water tank advantage of Bao Yougao is just many again, and the one, dwindled taking up room of washroom; The 2nd, can water tank appearance be done very exquisitely; Three are conducive to improve washing force and the displacement of sanitary equipment; The 4th, water tank both can be arranged within the walls, also can be directly installed on outside wall, very convenient; The 5th, reduced the use amount of these narrow resources of Rare Earth Mine.
