Description
Technical field
The present invention relates to sanitaryware articles for use field, especially a kind of cleaning effect is good, water-saving performance outstanding and the little overturning closet that has annular trap of floor space.
Background technology
No matter the flush toilet of present stage is fixed or pull, upset movable, all is to get rid of dirt in the toilet by the siphonage that trap produces, and comes the foul smell that floats in the shutoff sewer pipe with the water that retains in the trap.Wherein, the trap of fixed toilet is a S type passage, and this passage is arranged on the toilet rear, extends to certain altitude with miter angle to the back upper place and forms turn of bilge, and then be connected with sewer pipe downwards.For guaranteeing effective water, lower wall of turn of bilge must exceed the outlet at bottom of toilet on this.This form of structure, though can be well by water every the isolated come-up of water foul smell because its top outlet is higher than the outlet at bottom of toilet, therefore, siphon produces the initial stage, liquid can make to flow during adverse current from the bottom up and seriously be obstructed, influence cleaning effect.Simultaneously, be in the ight soil of toilet and trap bottom, when siphon initial stage translation with closestool bottom and trap friction, the resistance of ight soil adhesion formation, and the resistance of liquid self also can make the whole liquid flowing velocity become slow during adverse current.After particularly liquid enters sewer pipe from trap, produce current difference with the interior liquid of sewer pipe in the trap, in trap, produce the space and retain air, the air that retains is along with the impact of follow-up current has formed the air pocket with certain density gradually, hinder the proper flow of liquid, it is slower that liquid flow is got, and causes the cleaning effect variation, must strengthen the water for cleaning amount, cause water waste.A large amount of air pockets also can disturb even destroy normal siphon sometimes, cause liquid flow to interrupt, and make ight soil rest in the toilet, have to once more toilet be cleaned, and cause bigger waste.
Cause another big main cause of fixed toilet water supply volume also be to have only when the liquid level in the toilet is disposable exceed fast turn of bilge self on the trap higher go out open height the time just can form the siphonage of nature, this form has extended time that siphon forms and increased corresponding water supply volume naturally, has caused waste.Simultaneously, by form the necessary big quantity of fluid of siphon the ight soil mixed liquor of the inner a large amount of high concentrations that form with just body of toilet must be through the alternately dilution repeatedly of a large amount of follow-up clean water, exchange for a long time just can be so that ight soil concentration drops to minimum in the water, the corresponding cleaning that keeps water, the water supply volume maximum of its consumption is wasted the most serious.Although people have attempted adopting variety of way that the existing common trap of toilet has been carried out various improvement, comprise the control etc. of the flow regime of the formation that reduces as far as possible and avoid air pocket in the trap, water, but fail to break away from the puzzlement that the air pocket that produces in the trap hinders proper flow all the time.The function of particularly present trap only is confined to produce siphonage blowdown and water shutoff sewer pipe come-up foul smell, can't reuse water, and water-saving result is relatively poor.
A kind of water-saving toilet that has on the market at present, owing to be subjected to the influence of its volume, position, shape, structure and hardness, often in a flush cycle, can't realize effective cleaning with the water of limiting the quantity of to toilet, must be through secondary even repeatedly flushing repeatedly, this has just caused even more serious waste.The employing power drive that also has, as the cleaning way of additional form such as pump helps, though got certain water-saving result, it has only just adopted the form of power conversion, though water saving takes electricity, its resultant effect is relatively poor.
And movable toilets such as existing pull, upset, their outlet be directly by flexible pipe be embedded in underground common trap and be connected, therefore all be dry in its bottom, flushing discharging back, owing to there is not the isolation of water, can cause ight soil and the dry toilet inwall stronger adhesion of formation easily in use, make the cleaning difficulty that becomes more, must with a large amount of water repeated multiple times wash could be thoroughly cleaning closestool effectively, the toilet of this form is bigger to the waste of water.In order to overcome this drawback of drawing the toilet of taking out, overturn, the user who has can at first put into a certain amount of water in use and enter toilet, but this operation has increased user's work, uses extremely inconvenient.Although the corresponding quantitative automatic device of the employing that has solves this problem, but fail thoroughly to reach the purpose of water saving.
Though attempted adopting variety of way at present the existing common trap of toilet various improvement have been carried out, comprise the control etc. of the flow regime of the formation that reduces as far as possible and avoid air pocket in the trap, water, but fail to break away from the existence, each curved some angle too small of trap straight length top air pocket all the time and hinder the puzzlement of proper flow, the function of especially present trap only is confined to produce siphonage and discharges toilet interior content and water shutoff sewer pipe reflux gas, and water-saving result is corresponding relatively poor.
In addition, at present stage fixed toilet take the shortcoming of ground, the waste washroom usefull space relatively, people have attempted utilizing manners such as spaces formation pull, upset such as washbowl below, flushing tank bottom to improve the toilet putting position, but fail to find corresponding with it scientific and reasonable backwashing manner, solve the problem of health and water saving, on the contrary, even the unreasonable structure owing to changing that has caused the increase of water supply volume, caused even more serious waste.
Realize efficiently cleaning fast with a spot of water, need solving the improvement of toilet trap, the flow regime of horse inner bucket water be the control of the mode of eddy current, string stream etc., reduce in addition eliminate air pocket in trap formation and when toppling over by upset the closestool bottom retaining to problems such as just body dilute.Yet turn of bilge is higher than the closestool bottom outlet on the trap commonly used at present, the existence of air pocket in the trap, the existence that toilet inwall drying, the isolation that discharges water are difficult to problems such as controlling has caused traditional toilet can not realize rapidly and efficiently cleaning, reducing water supply volume, has optimized the purpose of beautifying the washroom.
Summary of the invention
To be solved by this invention is exactly that the employed trap internal resistance of existing traditional toilet is big, cleaning effect is poor, be easy to generate air pocket, and toilet itself takes up an area of the big problem in space, provides that a kind of cleaning effect is good, water-saving performance outstanding and take up an area of the little overturning closet that has annular trap in space.
The overturning closet that has annular trap of the present invention, comprise toilet main body, support and trap, support is fixed on ground or the wall, the trap inlet is connected with the sewage draining exit of toilet bottom part body, the trap outlet is connected with sewer by flexible pipe, the toilet main body is installed in the rotating shaft by the toilet arm, rotating shaft is fixed on the support, make the toilet main body overturn around the shaft, it is characterized in that described trap is the circulus that is turned to by hollow section, trap is centered around in the rotating shaft, and rotates around the axis with the toilet main body.
On the described trap ventilating pipe is set, the ventilating pipe two ends are communicated with the trap arrival end and the trap port of export respectively, to guarantee that trap still has water to exist in the trap after siphonic process finishes, are unlikely to drain.
Described ventilating pipe is made with pipe, the ventilating pipe inlet exports the gain shape that is pressed into prolate with ventilating pipe, and on the trap sidewall, be horizontally disposed with, the width of gain is no more than 1 centimetre, in siphonic process, can be passed into the air of liquid level top in the trap fast in the liquid of trap, effectively destroy siphonic process, it is empty to avoid siphonic process that the water in the trap is inhaled.
Described trapway conduits cross sectional shape is circular or oval, and trap enters the mouth to the nozzle diameter of trap outlet and reduces gradually, makes the pressure that the liquid of trap is subjected to of flowing through constantly increase, and flow velocity is accelerated, and improves the effect of siphonic process; The diameter in trap exit is littler by 5%～10% than the diameter of trap entrance.
Described trap enters the mouth one section to trap left side or right side skew, forms offset segment, and the liquid short time that order is flowed through, interior flow direction sharply changed, and made liquid in rotation flow, and produced siphonic process fast.
After described toilet was opened, toilet main body inner bottom part present position was higher than present position, trap bottom; Most preferably be in the medium position that the trap downward bent part divides; This toilet bottom part body is shaped as arc, and depth of accumulated water is 3 centimetres in the toilet main body, and pools zone field surface area is no less than 15 * 20 centimetres for best.
Described support top is provided with flushometer, and the height of flushometer is according to the different height of adjusting with normal areas in the key area of toilet main body flushing, to reach backwashing manner concentrated, that disperse.
Toilet material of the present invention is a kind ofly to have higher-strength and toughness simultaneously and have acid and alkali-resistance, aging-resistant high-strength engineering plastic concurrently, as acryl, or even metal material such as enamel.Also supporting simultaneously bearing, the toilet that seat cushion, water tank, self-closing valve, shower nozzle is arranged, be connected with the toilet rotating member close gap between back and body of wall the sealing frame, hide the exterior trim base plate and the bobbin carriage of the concavo-convex bottom of toilet and trap and flexible pipe, comprise the annexes such as movable supporting that improve the toilet steadiness, also can adopt opening/shutting mode such as inductance, foot-propelled and cooperation to close simultaneously and implement the supporting facility such as automatic device of flushing synchronously.
This invents described toilet, has an overall structure at the rear of toilet and is shaped as circular trap.The outlet opening of toilet main body connects the trap inlet, and the outlet of trap links to each other with the blowdown sewer pipe with flexible pipe, forms one from toilet main body outlet opening to be communicated with the sewer pipe, supply the passage of toilet content discharge.The two side at toilet main body rear extend back form the toilet arm and by rotating shaft be fixed in the form that support on floor or the wall is connected to form rotational structure.The annular channel of trap is circular to being ring between the outlet from inlet, does not have straight downward duct section, with respect on the common trap between the downward bent part straight length top be easy to generate for the air pocket, annular trap ring circular channel is not easy to produce air pocket.And, the trap passage can make the pressure of current constantly increase from inlet to the cross section that outlet is evenly dwindled gradually, the eliminating of air is more thorough in the passage, can make the flow through current of this circular passage fully smooth like this in whole siphonic process, and the flow speed of no air pocket interference is faster.Thereby the raising cleaning effect reduces corresponding water supply volume.
The entrance leading section of trap annular channel forms lateral bending to the side skew makes this section passage form the rapid variation of both direction in a short time, therefore, when current are flowed through this segment pipe, the drastic shift meeting of flow direction changes the flow regime of current in moment, form the liquid form of rotation, the centrifugal force that rotation produces can make current tend to be close to the vias inner walls rotational flow all the time, eliminate the formation of air pocket in vias inner walls, drain air in the passage, keep current unimpeded fast, improve cleaning effect, reach the water saving purpose.
When the entrance section of the ventilating pipe that is provided with on the trap is shaped as the gain shape of prolate and is horizontally disposed with, for the blow vent of circular or other Any shape, under the situation of equal section area, space length minimum because of its vertical direction, so the vertical plane with the liquid level contact also is the shortest, therefore it can finish corresponding air inflow with the fastest speed when the siphon later stage, liquid level dropped to best period, destroy siphon, stop flowing, guarantee that the water capacity that trap retains reaches best volume rationally, form sewer pipe is implemented effective shutoff and can rationally be refluxed rationally quantitative water after toilet is opened in toilet.In addition, this cross sectional shape can prevent effectively that bulky objects such as ight soil, toilet paper from entering ventilating pipe and causing obstruction.
When toilet was opened, the water meeting natural back flow in the trap was in toilet.When backflow reaches a certain amount of, when promptly satisfying trap water shutoff sewer pipe reflux gas and toilet water zone ponding simultaneously and isolating, in the effect of atmospheric pressure balance, in the trap and the water level in the toilet main body water district reach balance.The water yield of this backflow is relevant with the water field capacity of toilet bottom part body by trap water capacity.It is relevant with area with position height, trap channel diameter, the toilet water zone arc degree of toilet by trap.And the water in toilet main body water zone has formed one deck rational and effective liquid area of coverage in closestool bottom central authorities, then to the just body that falls into toilet effectively dilute, isolation and floating, cleaning is become to be more prone to, toilet after toppling over is more clean, improve cleaning effect, thereby reduce corresponding wash water amount.
When toilet cut out, trap was positioned at the below of toilet main body, because the effect of gravity, content mix liquid just can fall in the trap naturally in the toilet main body after the use, and enters sewer pipe by trap under natural pressure and siphonage.Like this, comparatively clean through the toilet of toppling over, again in conjunction with from top to bottom the straight vertical effect cleaning way of leaping high, only need in a small amount of clean water of trap water amount toilet add to wash and with this water the mixed liquor in the trap is replaced and retained to obtain cleaning performance preferably with equivalent.When this part is used for additional follow-up clean water of cleaning and contacts with mixed liquor in the trap, because the distinctive no air pocket of the quick siphon of high pressure of high low level and trap disturbs, current are the characteristics that rotation situation flows fast, former mixed liquor is short time of contact in follow-up water and the trap, follow-up in addition water and mixed liquor contact surface are little, therefore follow-up water is not easy to mix repeatedly mutually with the interior former mixed liquor of trap, moreover under the effect of ventilating pipe, can destroy siphon and make the trap water, so the follow-up water that is used for the relative cleaning of additional flushing can and be used as the resident water of trap, be used for the shutoff sewer pipe and when opening toilet, make recirculation water usefulness, finish a life cycle.
