Description
Technical field
The present invention relates to a kind of dewatering installation, such as, for the dewatering installation of hygiene sector, as the floor drain for shower.
Background technology
Such dewatering installation, in particular for the floor drain of shower, itself is for a long time known.Except discharging water from plane (as shower tray or ground) and being exported to by water except the function of tonic chord in waste water pipe network, dewatering installation in most of the cases has the smelly task of solution resistance.Can suspect, can run out of make us uncomfortable foul smell from waste water pipe network, these foul smell can be blocked by so-called syphon (drainage elbow namely in the pipeline guide portion of respective curved).Hinder smelly functional requirement and have certain safe clearance for expection from the pressure oscillation in siphonal evaporation and pipe network, hinder smelly function and impel in syphon two water level relative movements and substantially also the gas extrusion from waste water pipe net can be entered through syphon thus in the space that dewatering installation installs.Therefore, there is different regulations and standard, such as EN1253, it maintains resistance when considering certain evaporating loss smelly, and result is the overvoltage having the negative pressure state of the pressure of about 400Pa and have formed objects subsequently in waste water pipe network.
These and other standards are paid attention to usually in the following way, and the water seal height (water level namely in syphon and the difference in height between the highest possible gas penetration position) in syphon has the minimal size determined, such as minimum 50mm.In addition, proposed two syphon and hindered smelly, and this pair of syphon hinders smelly is introduced in practice, its (under meaning through dewatering installation flowing of water) has two siphon arrangement be connected in series to a certain extent.In effective water seal height, water seal height is divided into two parts by people in brief.So corresponding dewatering installation may be embodied as the general construction height having and relatively reduce, this has large advantage in different situations.Such as, expect in the planning of shower facilities by arranging floor drain below shower tray, and do not impose the setting height(from bottom) on complete unwanted floor originally in building.In some cases, in planning, even no longer changeable fringe conditions also produces restriction, especially in outdated building renovation.Interested is thus that two syphons that height reduces hinder smelly.
Summary of the invention
As background, the present invention based on problem be propose a kind of resistance smelly functional reliability in improved there is the dewatering installation that multistage syphon hinders smelly.
This problem is solved by a kind of dewatering installation, this dewatering installation has: the drainage cup of input side, connect discharge pipe line thereon and multistage syphon hinders smelly, described multistage syphon hinders smelly and has interior air zone, it is characterized in that, between the air zone of the edge side in described interior air zone and dewatering installation, air duct is set on the entrance side of described dewatering installation and/or on outlet side.Wherein preferred expansion scheme is explained in the dependent claims.These expansion scheme are the same with basic conception of the present invention hereinafter to be elaborated, and each feature wherein in the scope of effective claim 1 also other can combine and form the present invention; This is also applicable to embodiment.
Basic conception of the present invention is the air duct between the air zone of the edge side in dewatering installation and interior air zone.Interior air zone is the air zone surrounded between two siphon arrangement, and this nature is for inactive state when not having external pressure difference and each siphon arrangement to fill up along dewatering installation.The air zone of edge side is the air zone in the air zone before entrance side (first) syphon or the waste water pipe system after outlet side (last) syphon.
In preferred regular situation, the present invention relates to two syphon, therefore following discussion is not limited to the general common ground of the first and second syphons and air zone therebetween.In principle, therefore the present invention is also suitable for the syphon of three or more bunchiness, and is connected to air zone on first or last syphon in relating to (at least) as interior air zone.
In the siphon arrangement of three or more series connection, the air duct of respective numbers is also possible, wherein in principle siphon arrangement should keep as smelly of fully effective resistance and therefore not should with (but little) air duct " short circuit ".In two syphon situation, so preferably there is an only air duct.
Especially, after running a period of time at dewatering installation, when the mattress appeared in mentioned air zone is partially or completely washed out, namely two syphon hinder smelly approximate or actual when filling up, so this air duct works.Practice shows: exist following dangerous under these circumstances: the whole pair of syphon is drained and limits thus or lose its function with hindering smelly complete or very large degree.This such as more suddenly defines certain negative pressure at outlet side and water column is not only such as sucked but also just occurs with during significant impact.So water column can due to mass inertia, (fluidstatic) pressure amplitude also owing to illustrating is fartherly mobile, and therefore flows out smelly of resistance.
But due to air duct, in mentioned inner region can regeneration air pad and described substantially or actual effect of filling up few or will not adventurously act on.For this reason, when mentioned without external pressure difference and siphon arrangement is filled up inactive state in and certainly in correct installation site, relevant siphon level water level only slightly on open up air duct (namely this water level only slightly on there is passage), just enough.When the water level in siphon level is passed relatively by pressure differential, to be filled by water to the passage of air duct or whole air duct and close thus, the water level in siphon level can be contributed to stability that whole multistage syphon hinders smelly the described pressure of antagonism.Preferably, the highest 5mm on the balance water level being arranged in inactive state to the passage of air duct, and more and more preferred in the following order: in 4mm, 3mm, 2mm, 1mm.
In addition, air duct preferably has little cross section, because have time enough for it for function of the present invention.But just wishing little flow cross section, is first for reason mentioned above, because less flow cross section is associated with the low height of air duct relative to water level.Secondly, expect to form relatively large air flow resistance by air duct, when making pressure oscillation in waste line, air duct can not cause the short circuit of corresponding siphon level.In other words, the horizontal plane that can form siphon level due to the flow resistance caused by pressure differential moves, and air duct closes thus.Under this meaning, make every effort to the highest 10mm
2flow cross section (when filling up again relative to inactive state) and more and more preferred in the following order: be up to 8mm
2, 6mm
2, 4mm
2, 2mm
2flow cross section.
In principle, the multistage syphon that the present invention can be used in different structure mode hinders in smelly.Preferably " level " hinders smelly, wherein each siphon arrangement placed adjacent.Be interpreted as when this: it has the overlap (time in namely remaining static when filling up and in the installation site conformed with the regulations time) of nominal water level in horizontal projection (in installation site).Hinder smelly is favourable for the field with the dewatering installation of limited structure height referred to.
According to air duct principle of the present invention can be arranged on interior air zone and entrance side or and outlet side between, preferably air duct is arranged between interior air zone and outlet side certainly.Especially, what refer to is for this reason, when this structure, so the installation that the access portal of the air duct at the drainage cup place of input side does not also need with there or sealing device conflict, these are installed or sealing device especially can be arranged in the region be located immediately on nominal water level under limited structure height.Can reference example to this explanation.
Smelly of resistance according to the present invention is preferably single type, at least with regard to its outer wall, does not namely consider insert.Such as, can be plastic blown article, embodiment gives this point.
Air duct i.e. its border itself does not necessarily belong to the parts of single type, and especially it is contemplated that acetyl one of them parts has the connection possibility for flexible pipe part or pipe fitting, flexible pipe part or pipe fitting limit air duct and also can remove in needs situation.But preferably air duct is also integrated in the form of implementation in smelly of the resistance of single type.
In addition, syphon plug-in unit (namely for separating two water columns of siphon level) is not preferably set in drainage cup.This means: the syphon of entrance side is limited by one of them parts, namely by comprising the one single piece of outer wall.
In a preferred expansion scheme, air duct, the air duct especially in integrated form of implementation, opens wide downwards relative to the nominal water level of corresponding siphon level.Can say, " adding the penetrating part of top cover " of the lower open between two the nominal air zone relating to relevant siphon level, see embodiment.This form of implementation tool has the following advantages: possible dirt can drop downwards and air duct is also washed away regularly.
Advantageously following expansion scheme: this structure downwardly nominal water level is widened.This is preferably not only suitable for air duct itself, and is applicable to its structure of restriction below nominal water level.
In principle, the air duct in the present invention preferably between interior air zone and outlet side, namely in second or last siphon level.Usually and also preferably arrange less water seal height there within the scope of this invention, the structure of the air duct and thus in the flexible program opened wide downwards just mentioned is associated with less intervention.Independent of the specific expansion scheme of air duct, form the short circuit of water seal height in some way, it is therefore preferable that and make this be arranged on to have in the siphon level of less water seal height (this when limit without when air duct).Like this, this is also in this embodiment.Occur under many practice situation, more than entrance side, also connect longer vertical pipeline section or at least there is the line segments of vertical member.When first (entrance side) siphon level provides enough displacement of volumes on its other side, this means, when outlet side has overvoltage, the water seal height that horizontal plane exceedes set by itself in entrance area can raise higher, such as, until the entry grates of shower drainage groove.Thus, the larger over-voltage events in drainage pipeline system can be tackled, and there is no air penetration.
According to another expansion scheme of the present invention, the siphonal displacement of volume of the input side outside the drainage cup of input side is relatively large.First this be favourable when just describing.Specifically, the displacement of volume outside drainage cup is preferably at least 1.4 times of the volume of (i.e. entrance side) in drainage cup.In the following order, following lower limit is more and more preferred: 1.5 times, 1.6 times, 1.7 times or even 1.8 times.In this embodiment, volume is that about twice is large.But affecting physical dimension more than the value of 3 times or 4 times, is less preferred.
Such reservoir volume can by correspondingly widening cross section to realize.When such as due to external pressure difference, the horizontal plane in the drainage cup of entrance side is declined and therefore (evaporating loss) before not considering relevant horizontal plane in the reservoir volume increased raise and overflow to follow-up syphon time, the first siphon level loses quite few water seal.This reason is, because large cross section makes horizontal plane increase corresponding little stroke or can in the figure of alternative, squeeze in the drainage cup of entrance side and the volume lost by overflow occupies less share compared to large reservoir volume.Especially, when owing to there being great negative pressure in waste water pipe network by whole resistance smelly withdrawing air time, when the horizontal plane namely in the drainage cup of entrance side have dropped whole water seal height, also keep favourable deposit.
In addition in the case, the existence of other siphon levels is also responsible for the water from the first siphon level overflow is not lost.In addition, air dynamic effect (wave impact) is more weak, because there is less violent air flowing by pressure differential being divided into multiple level for each grade.So smelly of whole resistance has larger overall flow resistance to a certain extent for air.
In addition, the connection between the drainage cup of entrance side and the miscellaneous part of the siphon level outside drainage cup is preferably relative narrow and be the highest 10cm thus
2and it is more and more preferred in the following order: to be even only the highest 9cm
2, 8cm
2or even only 7cm
2.Alternatively, preferably account for the maximum cross section in drainage cup itself the highest by 70%, preferably the highest 65% or even only the highest 60% value.Such as, compared to Isosorbide-5-Nitrae 00mm
2(when the interior diameter of 42 millimeters), in this embodiment the flow cross section of most narrow portion position be approximately cross sectional area in drainage cup 50%, i.e. 700mm
2.Value under about 20% or 30% adversely increases flow resistance.
By constriction, achieve relatively high flowing velocity at this, make it possible to the precipitation overcoming dirt.In addition, structure height can be reduced in this manner.At connecting portion place, additional displacement of volume also can not have remarkable impact to the function of smelly of resistance.The level and smooth expansion scheme without arris, is especially conducive to avoiding dirt in the level and smooth expansion scheme without arris of the middle and lower part, whole region wall segment (interior) of the first siphon level equally.
The floor drain in hygiene sector is related to, especially shower drain according to the preferred application of dewatering installation of the present invention.Special advantage is safety in operation and simultaneously little structure height, and it is preferably the highest 7.5cm, more and more preferred in the following order: even only the highest 7.0cm or 6.5cm.In an embodiment, this value is 6.2cm.When obviously less value, need the siphon level more than two, although this within the scope of this invention may be not preferred.
Set forth the present invention in more detail referring to embodiment, this embodiment in the accompanying drawings in detail and illustrate pari passu.Illustrate in detail:
Accompanying drawing explanation

Fig. 2 with twice than being illustrated in Fig. 1 with the position that X represents;
Fig. 3 shows the lateral view corresponding with Fig. 1, and
Fig. 4 shows according to the sectional view in the main flow direction of the section plane represented with A-A in figure 3.
Detailed description of the invention
In FIG using longitudinal plan show as embodiment according to dewatering installation of the present invention.At this, the main flow direction of water from left to right and this view correspond to nominal installation position, which depict the nominal water level being provided with Reference numeral 1.Can see union 2 in left side, this union such as can be connected in downside on common shower drain and to allow when shower is carried out waste water from the floor drain formed by groove to dirty.Union 2 is inserted in the end widened of the cylindrical parts 3 of the draining cup-shaped of dewatering installation, and seals via the safety collar 5 of seal 4 and collar shape and keep.Structure described is so far rotational symmetric and itself is known.
The cylindrical parts 3 of drainage cup extends downwards in the no longer rotational symmetric portion section 6 of drainage cup, this section has inclined-plane 6 left and has the transition part 7 of elbow shape to the right, wherein inclined-plane 6 approximately flatly continues from the centre axis of the cylindrical parts 3 of drainage cup, and the parts of the rotation asymmetry of drainage cup relative to the diameter of cylindrical parts 3 towards the convergent slightly of the direction perpendicular to plotting planes, as represented in fig. 3.
Elbow 7 forms narrow portion and is connected by the external component 8 of drainage cup 3,6 with the first siphon level of dewatering installation.This external component has the bottom first only slightly and without arris raised to the right, wherein unlike this, top wall obviously raises from elbow 7 to the right and therefore can keep larger displacement of volume external component 8, displacement of volume is 210 cubic centimetres in the case, and this roughly corresponds to the twice of the displacement of volume in drainage cup.
At the right part place of outside reservoir part 8, diapire raises equally relatively by force until the first maximum portion 9 (relative to height), the level of the upper end of the first maximum portion roughly in the closed upper part portion widened of the cylindrical parts 3 of drainage cup.Being positioned at of first maximum portion 9 and more the right is determined nominal water level 1 together with mutually level second maximum portion 11 and is also determined the water seal height (i.e. the darkest point of the top wall of dewatering installation there) of the first siphon level relative to elbow 7 thus.Between the first maximum portion 9 and the second maximum portion 11, there is the second elbow 10, but the second elbow compared with the elbow 7 of the first siphon level by drop-down obviously comparatively not dark.
Top wall in the region of the second siphon level existed here compared with the top wall in the region of the first elbow 7 by drop-down comparatively not dark yet.Therefore, the second siphon level formed between two maximum portions 9 and 11 has obviously less water seal height.Top wall---when not considering the air duct also will discussed as follows---maintains the flow cross section substantially constant in the second siphon level by the spacing of its distance lower part wall between these two maximum portions 9 and 11, and this flow cross section is also significantly less than the flow cross section of upstream, wherein only the first elbow 7 has approximate suitable flow cross section.You need to add is that in the case, dewatering installation is substantially having identical width with between the second maximum portion 11 perpendicular on the direction of plotting planes at the non-cylindrical parts 6 of drainage cup.From the second maximum portion 11, also extend until maximum portion 11 continuous transition is the cylindrical tube portion section 12 for being connected to discharge pipe line with common mode and the more flat and wide channel shape of method.Fig. 4 with cross section A-A shows flat wide-pass shape, and this cross section A-A represents in figure 3, and illustrates in bosom and the second siphon level seen along flow direction.
, especially can see typical for the present invention air duct herein, that the dewatering installation namely it under actual is essentially the general triangular of the drainage channel of triangle (bight with rounding) and unlimited widening portion 13 downwards.Or rather, air duct is the zonule 14 of topmost, in the enlarging section of Fig. 2 shown with this zonule, and widening portion 13 usually water level on paper when fill water.But, nominal water level 1 keeps slightly under the inner upper side rib of widening portion 13, i.e. only about 0.2mm in the case, (in amount in inconsiderable scope) is short circuit when making the second siphon level water level on paper and when not having external pressure difference.Easily see, between entrance side and outlet side, (between the air in the air on the horizontal plane namely in drainage cup 3,6 and the cylindrical portion section 12 on right side) little pressure differential has eliminated air duct 14, wherein about 0.5mm
2little cross section produce large air flow resistance, make the negative pressure that occurs fast to a certain extent in systems in which or overvoltage condition is actual causes pressure differential and cause the change of horizontal plane thus.
The function of air duct 14 is, when occurring filling up in drainage procedure, between two siphon levels, namely on the horizontal plane 1 on the horizontal plane 1 of reservoir part 8, on the first maximum portion 9 and on the inner side of the second siphon level, mattress in setting up again, because this mattress can be washed out in time.The foundation again of interior mattress significantly reduces following risk especially according to experience of the present invention: whole dewatering installation is by by mistake complete or substantially emptying and its afunction or influenced in its function aspects.
In addition be appreciablely, air duct also can arrange and/or be set to the line segments of separating with rhone in principle and/or be arranged in the first siphon level with the form of non-integration, wherein in described last that situation, air duct must be arranged higher due to needs seal 4 and safety collar 5, this can deteriorated total height.Although this dewatering installation is interpreted as strictly be not with union 2, on safety collar 5, setting example, as the miscellaneous part of floor drain, be should give and taken into account in many cases.
Additionally it should be understood that the two syphons with similar logical construction of the present invention shown here also can have the siphon level more than two, then wherein air duct by the siphon level short circuit of outside, possible short circuit two.But in many cases, desired whole water seal height is divided into two siphon levels as herein just much of that.
In addition will be appreciated that: whole dewatering installation can be designed as one piece plastic blown article, comprise widening portion 13 and therefore air duct 14 or rather in the case.
Finally will be appreciated that, flowed through in each drainage procedure by the bottom main section (comprising widening portion 13) that water is filled under water level conditions on paper, especially washed away well, and there---owing to there is no ground---and seldom adhere to dirt, and the dewatering installation bottom design between the cylindrical parts 3 of drainage cup and the first maximum portion 9 obtains very level and smooth and is plane, although and have in 8 great reservoir volume also can not provide the position of easily polluting between storing, and especially can be washed away well bottom this dewatering installation.
