Description

The present invention relates to water closet, the formula of particularly squatting water closet, urinal have top edge, lower part outlet and a flushing injection well downhole flow regulator, and injection well downhole flow regulator is connected with an overhead water tank up.

This class crouching formula water closet generally is installed in underground, and its edge flushes with ground.Also do not provide a kind of gratifying flusher at present for this class water closet.A common reason is: this class water closet is used for the place of lack of water more, and flusher is often required to consume seldom water.Therefore using a water tank that is installed in the urinal next door very at large in order to flushing toilet bowl.

The object of the present invention is to provide a kind of crouching formula water closet of improvement, this is a kind of gratifying for this reason, but the just clean urinal of cleaning down of the water that only uses minute quantity.

For reaching this purpose, the feature of water closet above-mentioned should be: above-mentioned injection well downhole flow regulator mainly is made of an arc pipe that is positioned at below the urinal outside and the rear part edge, the mid portion of this pipeline is by some is on the lower side and some holes of lateral distribution are communicated with the Ce of position, urinal upper back at least, the two ends of pipeline are communicated with by the position, upper back of both sides, two holes and urinal inside, and this two hole is basically towards the front end of urinal.

The invention provides a kind of urinal that has injection well downhole flow regulator, injection well downhole flow regulator once uses very a spot of water, as 1 to 3 liter, just crouching formula water closet can be rinsed well.

Each embodiment that is described in detail the present invention below with reference to accompanying drawings and is recommended:

Fig. 1 is a water closet lateral view of the present invention.

Fig. 2 is the plan view of urinal shown in Figure 1.

Fig. 3 is the injection well downhole flow regulator drawing in side sectional elevation of urinal shown in Figure 1.

Fig. 4 is the drawing in side sectional elevation of second embodiment of urinal injection well downhole flow regulator shown in Figure 1.

Fig. 5 is the longitudinal plan of injection well downhole flow regulator shown in Figure 4.

Fig. 6 is the partial cross-sectional view of the 3rd embodiment of urinal injection well downhole flow regulator shown in Figure 1.

Referring to Fig. 1, urinal 10 shown in the figure with top edge 12 and lower part outlet 14.Urinal 10 is installed in the hole 16 on the ground 18 that is illustrated by the broken lines.There is the foot pad 20 of optional height on both sides, and foot pad 20 is represented by dotted lines in Fig. 2.Urinal 10 has the arc rear portion 22 of broad and two sidewalls 24 that shrink to arcuate front ends 26.Sidewall 24 is gone back contraction downwards and is formed bottom lands that tilt to rear portion outlet 14.

Urinal 10 has an injection well downhole flow regulator, and injection well downhole flow regulator generally represents with reference number 30, and it is made up of with a union elbow 34 that is connected with upper tank with pipe or flexible pipe arc pipes 32 that are positioned at below urinal 10 rear walls 22 outsides, the top edge 12.Preferably cover 36, in order to cover the space on 18 on edge 12 and ground round one of the vertical component installing of union elbow.

The detailed structure of injection well downhole flow regulator 30 is more clearly showed by Fig. 3 to Fig. 6, has illustrated each preferred embodiment of injection well downhole flow regulator.As shown in Figure 3, injection well downhole flow regulator 30 is overall structures with urinal 10.For example, this urinal can be made with ceramic materials such as porcelain.Upper rear end at urinal has a cross section to be generally semicircular horizontal channel 38, as shown in Figure 5.This groove 38 is communicated with pipeline 32 by the hole 40 on the rear wall 22.Groove 38 has downwards and the spout 42 that tilts to rear wall slightly.So just can wash rear wall 22 and make water flow to outlet 14 downwards by water.The hole 42 that illustrates on the figure is garden shapes, but covers rear wall 22, the hole that also can adopt other shape for flushing water is rationally distributed.Particularly the hole of keeping to the side most can be oval-shaped or can oblique a little side.On two sidewalls 24, be provided with level substantially and forward outlet 44.The section area of these two outlets 44 is greater than the section area of all spouts 42, and therefore the flushing current that provide are bigger.This flushing can be produced by action of gravity by the upper tank (not shown).Like this, the higher and current gone out of one inlet pressure are arranged at first, mainly along both sides forward end 26 bottom horizontal flow sheet.The current flow process that outwards flows out when inlet pressure descends shortens, and at this moment just is flushed to the lower sloping portion of sidewall 24.

Fig. 4 and Fig. 5 are second embodiment of injection well downhole flow regulator, are particularly suitable for the urinal of manufacturing with plastics or metal.Pipeline 32 has the L shaped pipeline 46 of arc rear wall 48 and the horizontal bottom 50 parallel with toilet rim to constitute by edge 12, urinal 10 rear walls 22 with one.The angled end wall 52 that is connected with the urinal wall body is arranged at two ends.The rear portion mid portion of rear wall 48 has a union elbow 34.According to urinal and the used material of pipeline, L shaped pipeline 46 can be connected with urinal 10 with suitable glue or weld seam 53.The rear wall 22 of urinal 10 is provided with center through hole 40 and side opening 54.There is guiding device 56 inboard of urinal wall, and it keeps off in the front of side opening 54, formation level exit 44 forward.Horizontal channel 38 is formed by a semicircle pipeline section or similar component 58, and its spout is made of hole 42, and groove 38 welds or is glued on the rear wall 22, covers the front at through hole 40.The general shape of second embodiment of the invention is identical with first embodiment of the present invention with function.

Shown in Figure 6 is the 3rd embodiment of the present invention, is the arc pipe 32 that is made of an independent pipe fitting 60.The outstanding advantage of this pipeline is: it can be installed on any kind of urinal, but as shown in the figure, it is specially adapted to the plastics urinal.But must on the urinal wall, be provided with rear portion central opening 62 and side mouth 64, be used for plug-in mounting spout member 66 and side exit member 68. Member 66,68 preferably has the circular section 70 of inserting, and on circle insertion section 70 otch 72 is arranged, and also has outside barb 74, is connected in order to tighten fast with pipe fitting 60.Pipe fitting 60 has and through hole 62,64 corresponding through holes 76,78.76,78 places are provided with circular groove 80 at through hole, and in order to the seal of packing into, preferably " O " shape sealing ring 82.Spout member 66 is provided with into the spout 42 of fan-shaped distribution.For flushing water can be dashed all over the urinal rear wall, the quantity of spout 42 and shape can be selected for use arbitrarily with corresponding with the shape of urinal rear wall.Two side outlet members 68 have the outlet 44 towards the place ahead.Because two side outlet members 68 are installed by means of cylindrical insertion section 70, therefore can change the direction of outlet 44, so that obtain desirable flush performance.What represent among Fig. 6 is a double wall 22, if but urinal 10 is porcelain does, just can adopt solid wall.

Can be changed the above structure.For example can in the 3rd embodiment, equip a plurality of spout members 66, in the first and second two embodiment, also horizontal channel 38 and spout can be set, for example be provided with on the next door of outlet 44 at other positions.

Can not adopt union elbow 34 and on the end face at edge 12 and pass edge 12 connector 34 is set.Horizontal channel 38 can all be got through with pipeline 32 substantially.Hole 40 just can not hinder the flushing current like this.

Will cause sizable drop when importantly above urinal flushing tank being installed, employing can discharge water fast and obtain the very opening device of high flow rate.Water will flow into injection well downhole flow regulator apace like this, and extrude flushing water by means of active force static state and dynamic.Thereby can use very limited amount water that whole urinal is rinsed well, generally need 1 to 3 premium on currency approximately.The prerequisite that realizes this point is the section area that the pipe section area between flushing tank and urinal is greater than the bath hole.

The jet water spout section area is 10: 1 to 10: 8 to the preferred ratio of injection well downhole flow regulator bath hole 42 and 44 section area summations, and optimum value approximately is 10: 5.

Because the import that hole 42 enters pipeline 32 near jet water spout, but promptly producing in flushing wink and have the highest pressure by hole 42, therefore the posterior medial surface of urinal is subjected to washing away, cleaning of water under high pressure in a quite short time, and only uses very limited amount water.

The shape and size at outlet 44 and connecting pipe two ends should make quite a spot of flushing water can produce quite high flushing speed, thereby the water capacity that discharges is easily covered on the whole length of urinal.

The invention is not restricted to described each embodiment, and change in following claim scope optionally.
