Description

The The invention relates to a waste set for washing or Sink, with a drain valve body, a to be arranged at the bottom of a sink or sink, with the drain valve housing connectable drain pipe piece and an operating rod for actuating a in the drain valve housing inserted valve body, the drainpipe piece being transverse to its vertical one Center axis running nozzle for feeding the operating rod to the valve body.

Such drain fittings are well known. They usually have a relatively long intermediate tube, which is connected in the vertical extension below the drainage pipe piece provided with the actuating rod at its outlet end and into a trap (siphon) opens, to which the actual drain pipe is connected (see, for example DE 195 04 793 A1 ).

Such Drain fittings whose valve body by means of an actuating linkage lifted from the valve seat and lowered onto the valve seat, have basically proven themselves in practice. However, they have the disadvantage that they are a convenient Use of existing under a sink space considerably limit. So are base cabinets for Washbasins today often still with recesses for recording the odor trap provided. This means extra effort for the furniture maker as well as a space reduction in the cabinet.

From the CH 132550 a drain fitting for sink is known, which has an operable by a linkage drain valve and arranged directly on the underside of the sink siphon housing. The located with the drain valve in contact part of the linkage is designed as a lever which is mounted by a two-piece ball joint on the siphon housing. Above the ball joint of the linkage, the siphon has a connection piece for a drain pipe, wherein the connecting piece rises upward to minimize the height difference between the outlet of the sink and the drainage mirror of the drain pipe.

From the JP 7071061 is a drain fitting for washbasin known in which a smell trap is located near the sink bottom to improve the space utilization option below the sink. The odor trap is formed from a cup-shaped part into which a dip tube protrudes, which is connected to a drain-valve housing together with a hood-shaped part of the odor trap. The hood-shaped part of the odor trap thereby engages over the cup-shaped part and has laterally a connection piece for a drain pipe. To actuate the drain valve, however, no linkage but a flexible wire is provided, which is guided in a sheath which penetrates the cup-shaped part on the underside thereof, so that one end of the wire is directed into the dip tube. For a washstand fitting with actuating linkage for a drain valve body this known drain fitting is not suitable.

Furthermore, in the EP 1 873 317 A1 proposed a relatively flat-fitting waste set for sink, having a directly to be arranged at the bottom of the sink drain body and a drain valve, wherein the drain valve is provided with an actuating pin which extends down into the housing and at the lower end of which seals a housing penetrating actuating lever attacks. The drain housing in this case has a lateral outlet opening, on which a horizontal, directed towards the back of the sink drain channel is formed.
