Description

The present invention relates to a siphon for connection to a basin, in particular a sink and washbasin according to the preamble of claim 1 and a piece of furniture according to the preamble of claim 8.

Conventional siphons for connection to a pool, for example, a sink, which is installed in a kitchen furniture or a sink, which is installed in a bathroom furniture, claim a significant part of the present under the basin storage space of the furniture. Especially with drawers special solutions are regularly required to avoid the siphon tube. If the basin and the siphon connected thereto are first mounted in a piece of furniture or behind a wall of a furniture carcass, the cleaning of such a siphon is also very complicated to carry out. In addition, when cleaning the siphon regularly feared that dirty water enters the furniture, which can lead to damage to the furniture.

From the US Pat. No. 7,107,634 B1 a siphon is known, in which prior to assembly of the siphon of two housing halves a rotatable on a rotation axis cleaning element is used with which serving as a liquid storage interior of the siphon can be cleaned by operating a rotary hub connected to the rotary hub. This document is considered to be the closest prior art. The preamble of claim 1 corresponds to this document.

From the DE 299010 426 U1 a odor trap for washing machines or dishwashers, sink or the like is known, in which two housing shells, which are each provided with a neck and a part of the walls of a labyrinth-like channel, and on the open side have a sloping boundary surface, wherein the housing shells this obliquely extending boundary surface are permanently connected to each other. From the FR 2 791 372 A1 is a set of two components siphon with a floor drain known.

From the AT 410 812 B is a submerged under plaster box element for receiving connection and discharge elements, including a siphon, known in the
From the DE 39 31 226 A1 is a washbasin console for sinks and sinks known, to which from a drain a via a designed as a U-tube siphon leading drain pipe can be connected.

The object of the present invention is therefore to provide a siphon for connection to a basin, in which the siphon consumes less usable space of the furniture and which can be cleaned in a simple manner.

This object is achieved by a siphon for connection to a pool, in particular a sink or sink, with the features of claim 1 and by a piece of furniture with the features of claim 8.

According to the invention, the siphon allows access to a arranged in the liquid storage, formed from at least two half-tubes full pipe. The liquid reservoir is openable by a removable cover such that access to the arranged in the liquid storage, the inlet extending full pipe, wherein formed on the liquid storage side facing the lid, a first half-tube, which together with an integrally formed in the liquid storage second Half pipe forms a subsequent to the inlet full pipe.

This allows a quick and easy cleaning of the siphon. Due to the division of the drainage pipe in the area of the siphon, on the one hand a supply of the wastewater in one piece of pipe is ensured. On the other hand, this pipe section can be cleaned quickly and easily by simply removing the cover. This allows access to the inlet and blockages can be easily removed, thus avoiding the use of chemicals or other mechanical cleaning equipment. The blockage can be eliminated without tools. The dividing joint and the front joint on the half pipe are sealed.

According to one embodiment variant, the siphon has a frame encompassing the liquid storage, on which a flap covering the lid is arranged pivotally. If you open this flap and then opens the lid of the siphon, so existing in the liquid storage liquid can flow through the flap in a placed below the flap drip tray without contaminating the furniture or the furniture contents.

In order to promote a targeted outflow of the liquid stored in the liquid store via the flap, according to an embodiment variant of the invention, a depression is formed on an edge of the flap opposite the pivot axis.

The lid is preferably circular and closed with the liquid storage preferably via a bayonet lock. It is any shape for the lid and the housing conceivable, it is not set to circular. Also, the closure is not fixed to a bayonet lock, other closure solutions such as e.g. a screw cap conceivable. This allows easy and tool-free maintenance of the siphon. The liquid storage serves as an odor trap according to the principle of dipping.

In a furniture equipped with such a siphon a placement of the siphon is no longer necessary directly under the sink or sink, so that can be apart in such a piece of furniture before installing a specially designed drawer in the furniture body or a cutout in the ceiling of a piece of furniture ,

According to one embodiment, the siphon is attached to one of the vertically standing walls of the furniture body, in particular embedded in a recess of the vertical walls of the furniture body. As a result, the siphon is arranged in a particularly space-saving and storage space gentle manner in the furniture body. Such a trained siphon is particularly suitable for installation in lightweight furniture and / or in motorhomes, caravans or boats, ie anywhere where congestion or working space is tight and therefore the most efficient use of existing storage space is placed. The installation of the siphon behind or in a bathroom wall is also conceivable.

The flap of the siphon is in accordance with a variant of the furniture in the closed state extremely space-saving flush with a utility space facing side of the vertical wall of the furniture body. In this case, an opening device is provided by ejection elements, by pressing the flap in the closing direction, the opening device is actuated and the flap opens so that the operator can comfortably reach behind them to then manually open them completely. Furthermore, it avoids that odors from the area behind the flap, e.g. can escape from the cleaning process.

The respective unused drain of the siphon is replaced by e.g. closed a stopper. It is also conceivable that both drainage openings are closed upon delivery and the respectively required drainage opening is released by breaking out of the closure elements.

The flap can be connected via a pivot axis on the frame of the liquid storage, but there are various other possibilities for mounting the flap conceivable.

In a further preferred embodiment, the liquid reservoir, the inlet and the at least one outlet of the siphon are formed protruding from a side facing away from the useful space of one of the vertically standing walls of the furniture body. This makes it possible that the siphon, for example, between two juxtaposed furniture parts or behind a furniture back wall is arranged and thus does not take the utility or storage space of the furniture.

In the following description of the figures, terms such as top, bottom, left, right, front, back, etc. refer exclusively to the exemplary representation and position of the siphon and other parts selected in the respective figures. These terms are not meant to be limiting, that is, by different working positions or the mirror-symmetric design or the like may change these references.

In the FIGS. 1 to 6 First embodiments of a siphon 1 according to the invention are shown. Such a siphon 1 has an inlet 3, which directly or via a (in the FIGS. 12 to 14 shown) connecting pipe piece 26 to a basin 24 can be connected. The basin 24 is designed in particular as a sink for installation in a kitchen furniture or as a sink for installation in a bathroom furniture. In particular, the basin 24 is designed so that it, as in the Figures 12 and 13 shown in a ceiling or worktop 25 is completely retracted.

The inlet 3 is extended into the interior of the siphon 1 out and opens into a liquid reservoir 2, in which a predetermined amount of liquid which has entered via the inlet 3 in the siphon 1, can be stored. The storage of this amount of liquid is used, as is the case with conventional siphons, as an odor barrier. From this liquid storage 2, at least one drain 4, in the embodiment variant shown in the figures, discharges two outlets 4 and 5, which are connected to a drainage pipe 31 (also into the drainage pipe 31) FIGS. 12 to 14 shown) is connectable or are. The respective unused sequence 4 or 5 is via a plug 36, see FIG. 10 , locked.

In contrast to conventional siphons, in which the liquid storage is designed as a S-shaped pipe section, the siphon 1 described here is designed so that it can be attached in a space-saving manner to a preferably vertical side wall 22 of a furniture body 30, as in the Figures 12 and 13 is shown.

In addition, the liquid storage 2 is designed so that it is easy to clean. For this purpose, the liquid reservoir 2 is formed by a removable cover 10 closable. As exemplified in FIG. 11 shown, the lid 10 is dimensioned so that it forms the circular end face of the cylindrical liquid reservoir 2. To open and close the lid 10 strips 18, 19 are arranged on a lid inside and on one of the frame 6 of the siphon, with which the lid 10 on the frame 6 of the siphon 1 can be fixed. To open the lid 10, the lid 10 is a vertically through the center of the circle of the lid surface rotated standing axis and then lifted in the direction of this axis of rotation of the frame 6 of the siphon 1. To stabilize the lid 10 and to facilitate the execution of a rotary movement of the lid 10 by a user, the side facing away from the liquid storage 2 side of the lid 10 is reinforced by cross struts 14.

As further in the FIGS. 6 or 9 is clearly visible, on the inside of the lid 10, a half-pipe 17 is formed, that together with an integrally formed in the liquid storage 2 second half pipe 16 forms a subsequent to the inlet 3 full pipe. This allows access to the inlet and blockages can be easily removed, thus avoiding the use of chemicals or other mechanical cleaning equipment. The blockage can be eliminated without tools.

The frame 6 of the siphon 1 is preferably of rectangular shape and preferably has a slightly offset from the outer edge of the frame 6 inwardly socket 7, on the one hand a positive retention of the siphon 1 in a the dimensions of the socket 7 corresponding recess in a side wall 22nd a furniture carcass 30 is used. On the other hand, a flap 9 is pivotally arranged within this version 7, which covers the lid 10 in the closed state. In the installed state of the flap 9, the pivot axis is arranged so that it extends in the region and parallel to a lower horizontal side of the frame 6. Preferably, the side walls of the flap 9 are pierced by a respective rotary nipple 15, with which the flap 9 is pivotally held on the socket 7. For locking the flap 9 on the socket 7 9 locking means 12 are provided at the upper horizontal edge near side edges of the flap, which can be latched with corresponding protuberances 35 on the inner sides of the socket 7.

In order to open the flap 9, in a first embodiment of the flap 9 at one of the pivot axis of the flap 9 opposite edge of the flap 9 a trough 11 is formed, which can be engaged behind by a finger of a user and so the flap. 9 can swing down. The trough also serves to guide effluent from the flap during a purge operation of the siphon 1. During such a cleaning operation can be placed below the unfolded flap 9 on a bottom 21 of the furniture body 30, a catch basin 20 which catches the effluent when opening the lid 10 from the liquid storage 2 effluent. In this way, contamination of the furniture interior is avoided.

In an alternative embodiment for opening the flap 9 'are, as in the FIG. 3 to recognize within the socket 7 in the area of the upper corners spring-loaded ejection means 13 arranged in the closed state of the flap 9 'on an inner side of the flap 9' and by pressing a user against the outer surface of the flap 9 'the flap 9' at subsequent release from the frame 6 of the siphon 1 pushes outwards. The user can open the flap 9 'by engaging behind the flap 9'. The flap 9 'closes the housing completely and thus forms an odor trap. Odors in this area can be caused by residues from the last cleaning process.

The in the FIGS. 7, 8 . 12 and 13 can be seen, the siphon 1 is preferably attached to one of the vertical walls 22 of a furniture body 30. The attachment takes place with the help of the frame 6 of the siphon 1. It is, such as in FIG. 1 to see the frame circumferentially provided with holes 8, so that the siphon is thus fastened to a wall 22 of the furniture body 23, for example by screws.

In order to install the siphon 1 as space-saving as possible on one of the side walls 22 of the furniture body 30, the siphon 1 is preferably recessed in a recess in one of the vertical walls 22 of the furniture body 30. In this case, the siphon is held in addition to the screw through the holes 8 and arranged on the frame 6 vertically protruding from the frame surface socket 7, wherein the outer edges of the socket 7 conform to the inner edges of the recess in the furniture wall 22.

Another advantage of this arrangement is that the flap 9 of the siphon in this way can be conveniently folded inwards into a utility space 32 of the furniture body in order to release the lid 10, which is then turned up to clean the siphon 1. In the closed state of the flap 9, the flap 9 is flush The siphon 1 thus assumes no required for storage of objects useful space 32 of the furniture body 30 in the normal operating condition a with the useful space side facing the vertical wall 22 of the furniture body.

especially the FIG. 9 shows sealing grooves 37 and 38 on the half tube 17. In the sealing grooves 37 and 38 seals not shown here are inserted, through the gaskets composed of the two half tubes 16 and 17 full tube gas and liquid sealed. The seal inserted in the sealing groove 37 seals on a sealing surface 39 on the half-pipe 16. A sealing cone 40 on the cover 10, together with a sealing surface 41 on the cover 10 and a sealing surface 42 on the liquid reservoir 2 seals the liquid reservoir 2.

As in the Figures 12 and 13 As shown, the siphon is preferably arranged between two vertical and spaced apart walls 22, 34 of juxtaposed or successively arranged parts of a furniture carcass 30 with separate utility spaces 29, 32 in a gap 33. In this case, the liquid reservoir 2, the inlet 3 and the at least one outlet 4 of the siphon 1 are arranged between the two utility rooms 29, 32 of the furniture carcass 30 and therefore do not consume valuable useful space of the furniture.

As in FIG. 14 can be seen, which is connected to the inlet 3 of the siphon inlet pipe 26 may also be designed so that the waste water from several sources can enter the siphon. Furthermore, this inlet pipe 26 may also have further connections 27, 28 to which, for example, a rinsing or washing machine can be connected and whose waste water can be introduced into the siphon via the connections 27, 28.

In the Figures 10 and 12 Furthermore, the flow of waste water from a tank 24 through the inlet pipe 26 into the siphon 1 in and from there further into a drain pipe 31 is shown. As far as the wastewater reaches the siphon 1, it is passed from the inlet 3 forth coming through the composite of the two half-tubes 16, 17 full pipe in the lower region of the liquid reservoir 2. From there, the wastewater rises laterally in the liquid storage 2 until the level of the wastewater has reached the height of the drain 4 or the drains 4, 5 and from there flows further into the drainage pipe 31. <B> LIST OF REFERENCES </ b> siphon 1 liquid storage 2 enema 3 procedure 4 procedure 5 frame 6 version 7 drilling 8th flap 9 flap 9 ' cover 10 trough 11 latching means 12 discharge aids 13 crossbars 14 rotary nipple 15 half pipe 16 half pipe 17 strip 18 strip 19 catch basin 20 ground 21 walls 22 furniture body 23 pool 24 countertop 25 inlet pipe 26 connection 27 connection 28 utility space 29 furniture body 30 waste pipe 31 utility space 32 gap 33 walls 34 protuberances 35 Plug 36 seal groove 37 seal groove 38 sealing surface 39 sealing cone 40 sealing surface 41 sealing surface 42
