Description

Technical field

The invention relates to a waste siphon, in particular a built-in siphon, such as a built-in siphon for washing machines, with a housing having an anti-odor closure and a side wall with a liquid inlet opening, and a liquid outlet opening disposed in the bottom region thereof; has a partition which forms with the housing walls a waste channel which extends from the inlet opening first down to the bottom region, connected to the upwardly extending and extending channel therefrom, connecting to the bypass channel leading therethrough through the inlet opening and finally down to the outlet opening opening and an outlet channel connecting to the bypass channel.

BACKGROUND OF THE INVENTION

Such a siphon, which has proven itself in practice by its flat design, is known, for example, from AT-B-343 555. This siphon, by means of a ball arranged in the waste channel, prevents the occasional kickback of dirty water from other household appliances such as Dishwasher or the like, or from the drain system, could not enter the machine while it is out of service and connected to the siphon.

A special way of forming the channels which are provided in the interior of the siphon housing allows, in addition to a particularly flat, and therefore preferably recessed, recessed wall design, a high flow velocity of the liquid to be drained at the points of the channels where dirt could accumulate so that such accumulation of dirt in the housing can be further avoided.

Further, from US-A-788 454, a siphon for waste tanks, such as a sink or a bath, with a screw-on closure is known. Here, the unscrewable closure forms part of the housing so that the interior of the housing is accessible. However, the drain channel that connects laterally to the housing is difficult to access.

ZGB-A-9440 is also known from the 1903 WC ceramic ceramic water seal. This water seal has an opening on its top flange that can be closed with a screw cover, the opening being arranged on the neck of the water seal.

SUMMARY OF THE INVENTION

The invention aims at a further improvement in the introduction of said siphon in such a way that, in a simple manner, it is possible to remove any accumulated dirt or debris in a simple manner without disassembling the siphon. clogging in the waste pipe system, which is connected to the outlet opening, resp. backflow caused by the backflow channel.

This object is solved by a siphon for the installation of waste, in particular a built-in siphon, such as a built-in siphon for washing machines, with a housing having an anti-odor closure and a side wall with a liquid inlet. the closure has a partition which forms with the walls of the housing a waste channel which extends from the inlet opening down to the bottom region, the upwardly extending and extending channel therethrough, connecting with the bypass channel extending therethrough, an outlet opening leading to a bypass channel extending to the bypass channel. According to the invention, the housing has an outer closable top opening which opens into the bypass channel and / or into the outlet channel.

AND

By means of a special opening arrangement, a cleaning tool, such as a cleaning spring, has been able to get into the waste channel in a simple manner and there, as well as in the drain channel, to remove the deposited dirt.

According to the invention, a particularly simple cleaning option is provided in that the upper opening opens at least partially into the descending branch of the bypass duct which connects to the outlet duct, wherein the upper opening is further preferably formed by a sleeve which connects to the housing.

A particularly space-saving hole arrangement, especially for the siphon, can be achieved by connecting the inlet opening with an approximately horizontal inlet throat that extends outwardly from the housing and the sleeve is arranged to rest partially against the housing and partially o inlet throat.

Preferably, the sleeve is sealable by means of a protective cap which is screw-tight onto the sleeve and provided with a seal.

In order to allow the siphon to be easily installed in the wall and to ensure that the opening is accessible, a cover is provided on the housing, which surrounds the upper opening or spaced apart from one another. and further preferably, the cover hatch 20 is mounted by means of a snap connection on a bracket part which is arranged on and protrudes from the housing.

A simple design of the cover cover is characterized in that the cover cover is open towards the side wall of the housing on which the inlet opening or the opening is arranged. the inlet throat mounted on the inlet opening.

In order to safely avoid overlapping of the closable opening with building materials such as mortar and siphon damage during and after installation in the wall, e.g. subsequent plastering or lining of the wall, it is advantageous to cover the cover and at least the part of the housing carrying the inlet or . an inlet throat adjoining the inlet opening associated with the protective cover 30, wherein the protective cover further preferably has a free edge which is slidable over the cover and at least partially over the housing.

In order to adapt the protective cover to the depth of the siphon installation, the side walls of the protective cover are preferably provided mutually with respect to each other and to the front wall of the protective cover by means of conventional grooves.

To facilitate the adaptation of the protective cover, the grooves are interrupted by slot-like recesses which penetrate the side walls, whereby a cutting tool can be used in a simple manner.

In order to achieve good accessibility to the opening and closure of the opening despite the flatest possible siphon design and despite the low installation depth, the front side wall of the housing having the inlet opening is arranged starting from the bottom of the housing bottom towards the rear wall of the housing sleeves, inclined.

Overview of the drawings

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a vertical cross-sectional view of a siphon that is built into the wall; FIG. 2 is a cross-sectional view taken along line Π-II in FIG. 1; ΠΙ-ΙΠ of Fig. 2.

DETAILED DESCRIPTION OF THE INVENTION

The construction shown in the drawing relates to a siphon for installation in washing machines. The siphon has a plastic housing L made of an anti-odor closure. The waste water of the washing machine enters the housing 1 through an inlet opening 2 which is provided on the side wall 3 of the housing 1. In the region of the bottom 4 of the housing 1, an outlet opening 5 for waste water is provided. Both the inlet opening 2 and the outlet opening 5 are connected with necks 6, 7, which are preferably made in one piece with the sleeve 1. The inlet throat has an external thread 8 to which the washing hose of the washing machine can be screwed.

The housing 1 has a rectangular flat cross-section in the horizontal direction, as can be seen in particular from FIG. 3, thereby obtaining only a small installation depth 9.

The odor closure comprises a partition 10 provided in the interior of the housing 1 and walls 11,

12. 13 of the housing 1, wherein the partition 10, as seen in particular from FIG. 2, extends from the outlet opening 5, surrounds the inlet opening 2 and extends with the free end 14 up to the bottom 4 of the housing 1. The partition 10 thus forms with the walls 3 , 11, 12, 13 of the housing 1, a waste channel 15 which extends from the inlet opening 2 down to the bottom 4 of the housing 1, the upwardly extending riser channel 16 connecting thereto and connected thereto and via the inlet opening 2, i.e. the part 17 of the partition 10 surrounding the inlet opening 2 leading the bypass channel 18, and finally downwardly into the outlet opening 5 and the outlet channel 19 connecting to the bypass channel 18. 4χ, Ρχ, P ₄ .

In the drain channel 15 which extends downstream from the inlet opening 2, a ball 20 is provided which, in the event of backflow, closes the inlet opening 2. The closing position of the ball 20 is shown in dashed lines in FIG. The sphere 20 consists of a material having a specific gravity slightly less than the specific gravity of the waste water.

Underneath the inlet opening 2 is a lower opening 23 which can be closed by means of a shut-off flap 21 and a seal 22, which serves to fit a ball 20 and which further allows cleaning of the waste channel 15 and the discharge channel 15 respectively. removal of foreign bodies.

The housing 1 has an upper sealable upper opening 24 on its upper part which, according to the illustrated embodiment, flows into the bypass channel 18, at least in part, into the outgoing branch 18 'of the bypass channel 18, in which the waste water flows back down again. By means of this upper opening 24, which can be closed by a protective cap 25 with a seal 26, a cleaning spring F can be introduced in a particularly simple manner, as indicated by the dashed line, directly into the drain channel without having to disassemble the siphon. The upper opening 24 is formed by a sleeve 27 which is arranged on the housing 1 at a distance from its rear wall 13 and which is supported by a supporting wall 28 on the inlet neck 6 and on the upper housing part.

AND

In order to be flat in spite of the arrangement of the upper aperture 24 and to require only a slight installation depth, the front side wall 3 of the housing 1 having an inlet opening 2 is bevelled starting from the bottom 4 when the cross-section of the housing 1 narrows. Thus, a sufficient clearance has been created on the front wall in the upper region of the housing 1 for arranging the upper opening 24 with the protective cap 25, so that the protective cap 25 can be easily handled in a very small space. By these measures, the narrowing of the cross-section in the interior of the housing 1 affects the increase in the flow rate of the waste water and thus a good self-cleaning of the siphon.

In order to allow the siphon to be easily incorporated into the wall when the upper aperture 24 with the protective cap 25 is loosely arranged, it is provided with a cover 29 which is open to the front of the siphon and extends the rear wall 13 as well as the side first and second walls 11, 12 This cover 29 surrounds the upper opening 24 and the upper opening 24, respectively. The protective cap 25 can be screwed onto the sleeve 15 at a distance of 30, so that the protective cap 25 is easy to handle and, in addition, a sufficient space is provided for introducing the cleaning spring F. The protective cover 29 is preferably not formed in one piece with the sleeve 1. by means of a latching connection 31, wherein on the upper part of the housing 1 there are arranged laterally extending bracket members 32, which at their end are provided with latching noses 33, on whose opposite latching noses 34 the cover can be fitted.

In order to avoid damage to the siphon during installation, resp. in order to prevent the penetration of cleaning material or dirt into the cover hood 29 or the inlet throat 6, a protective hood 35, preferably made of polypropylene or recyclable plastic 25, is provided with its free edge 36 slidable over the hood 29 and the housing L retract. The front wall 37 of the protective cover 35 is provided with a depression 38 into which the inlet throat 6 can be inserted, thereby ensuring a good fixing of the protective cover 35 on the siphon.

On the outside of the protective hood 35, mutually parallel grooves 39 are formed on the side walls surrounding the end wall 37, so that the unnecessary part of the protective hood 35 is cut off and removed in a simple manner. parts that overlap the finished panel, respectively. The remaining portion of the cover 29 remains walled. The cutting can be facilitated by the groove 39 of the interrupting notch cuts 39 ', which penetrate the side walls and allow a secure insertion of the cutting tool.

The front cover plate 41 having a through hole for the inlet throat 6 can be lined with a siphon.

The invention is not limited to the embodiment shown in the drawings, but may be modified in various respects. For example, the siphon can be used in a similar manner to other apparatus, such as dishwashers, suction pumps, etc. The top opening 24 does not necessarily have to flow into the bypass duct 18 but can also exit into the outlet duct 19 which connects to the bypass duct 18.
