Description

A kind of closet

Technical field

The utility model relates to a kind of sanitaryware, is specifically related to a kind of closet that is used for the washroom.

Background technology

Along with the human living standard with to the raising of hygienic requirements, latrine pit is replaced by the washroom that the two separates gradually with the lavatory that manure pit connects together, squat over a pit to relieve oneself and manure pit also respectively by closet and apart from each other with it, and the septic tank that is connected by the pipeline that seals is replaced.This has produced extremely useful effect to improving the human beings'health level.Yet, designed at present and produce closet, no matter be pan or toilet, also no matter be water flushing or clean covering with foam, all exist a drawback, that is: in the design of the bath circle on closet top, there is a following problem: the one, the rear end (promptly nearer apart from a sewage draining exit end) that bath is enclosed is low than front end (end promptly far away apart from sewage draining exit), the 2nd, the weep hole on the pipeline of bath circle, its pore size unanimity, and weep hole is uniform along whole bath circle length.Though the design of above-mentioned bath circle can realize dashing just and the purpose of cleaning urinal basically, but still have the following disadvantages: because the rear end of bath circle is low than front end, and the weep hole pore size unanimity on the bath circle, weep hole is equidistant uniform along whole bath circle length, the water of water tank is in flushing toilet bowl, have only a spot of water can arrive the front end of closet, a large amount of water directly flows to sewage draining exit from bath circle rear end, and the flushing of urinal is not produced any effect.Therefore, urinal wash down poor effect, water consumption is big, sometimes in order to wash down urinal, the flushing that need repeatedly discharge water causes the significant wastage to water resource.The urinal of this project organization, particularly non-flushing washing, but adopt foam to clean and when covering urinal, the foam that arrives the urinal front end is less, clean effect is poorer.The 3rd, the cross section of bath circle pipeline is generally circle, and do not stay the dead angle in order to make whole urinal wall all obtain flushing, weep hole on most of urinal bath circles is not the lowest part of design at this pipeline section, but at the middle part along urinal wall place, therefore, just form the groove of a loop product water in the bath circle pipeline, be easy to fouling in this groove and cause weep hole to stop up, further cause the reduction of developing result.And scale removal is an effort in the bath circle, trouble and very difficult thing.Though the lowest part that the water hole is positioned at pipeline section is irised out in the bath of minority urinal, can ponding in the pipeline of bath back, the dead angle between pipeline outer wall and urinal wall is again less than flushing.The 4th, also there is a defective in design in urinal: the sewage draining exit lower end is not sealed, but design has a return trap staying the surplus water of part with the shutoff foul smell, but surplus water often can not be blocked whole return trap, and foul smell can turn back in urinal and the washroom.And, owing to present closet is made by pottery, and moist potter's clay blank easy deformation, return trap is made not only trouble and cost of manufacture height.

Summary of the invention

The purpose of this utility model is the structure to existing closet, and particularly bath circle and sewage draining exit improve, provide a kind of simple in structure, cost of manufacture is low, has certain water-saving result, wash down effective, in the bath circle and weep hole is less scaling and can block the closet of foul smell.

The purpose of this utility model is achieved in that this closet comprises urinal 1, the bath circle 2 on urinal 1 top, sewage draining exit 3, the weep hole (7) on the bath circle (2) is arranged along urinal wall one side, and it is different from existing closet part and is: the front end of bath circle 2 is lower than the rear end; The cross section of bath circle 2 pipelines is a semicircle 4, and its semi circular surface 5 up; Bath circle 2 from the rear end along both sides to front end, the aperture of the weep hole 7 on it is strengthened gradually, weep hole 7 quantity on bath circle 2 unit lengths increase gradually; In closet sewage draining exit bottom one flap valve is arranged.

The purpose of this utility model can also realize like this: pipeline section is semicircle 4 bath circle 2, and the straight portion 6 of its semi-circular section is a horizon.Weep hole 7 on its bath circle 2 is positioned at the straight portion 6 of semi-circular section and the urinal wall place of semi circular surface 5 boundaries.Perhaps, pipeline section is semicircle 4 bath circle 2, and the straight portion 6 and the horizon of its semi-circular section have an angle.Weep hole 7 on the bath circle 2 is positioned at the urinal wall place of low side and semi circular surface 5 boundaries of the straight portion 6 of semi-circular section.Described flap valve 8 is that one one end has balancing weight 9, and the other end is and big circular cover such as sewage draining exit 3 grades, utilizes lever principle to be disposed at sewage draining exit 3 bottoms.

The beneficial effects of the utility model are, because the front end of bath circle 2 is lower than the rear end, and bath circle from the rear end along both sides to front end, the aperture of the weep hole on it is strengthened gradually, weep hole quantity on the bath circle unit length increases gradually, and therefore the water outlet of bath circle front end is more, the current direction rear end sewage draining exit of urinal front end, washed whole urinal bottom, good washing effect.Even the minimizing discharging quantity of water also can reach and clean effect preferably, more need not repeatedly to wash, saved water.But again owing to do not had the groove of ponding in the circle pipeline of washing by water, the interior and general non flouling behaviour of weep hole of circle pipeline of therefore washing by water.Exempted the trouble of bath circle inside and weep hole fouling.Owing to added flap valve in urinal sewage draining exit lower end, foul smell be can block and urinal and washroom returned, the washroom air is purified; Owing to saved return trap, simplified making, reduced cost.Using foam to remove under the situation of ight soil and covering urinal, the utility model structure more can obtain splendid effect.
