Definitions

  • the invention relates to a drainage system for basins such as hand or laundry sinks, particularly those of highgrade steel, steel enamel, cast metal, or plastic, having an overflow downpipe and a drainage pipe.
  • the overflow is the source of frequent and various disadvantages. Since the drain water must be conducted through guide channels or pipelines from an opening in the region of the upper sink rim into the drain connection pipe or the discharge pipe, and these guide channels or pipes must be accommodated in most cases within a narrow space, the conduits must perforce be bent at acute angles or be constricted, resulting in narrow flow cross sections for the drain water. Under such circumstances, it cannot be avoided that the channels or pipelines clog up. Consequently, apartment floors are often fooded when an occupant using such sinks relies on the function of overflow and realizes too late that the overflow is clogged. The removal of such obstructions in the channels or pipes conducting the overflow water is connected with a substantial expenditure in time and work and is quite diflicult. In many cases, the basins and pipe systems must be substantially disassembled, so that plumbers must be called in.
  • the walls In case of basins made of steel, steel enamel, or plastic, the walls have a thickness of only 1 mm. or 2 mm, so that a special overflow pipe must be provided outside the wall.
  • a special overflow pipe In order to connect the overflow pipe between 3,431,566 Patented Mar. 11, 1969 the overflow opening in the upper region of the basin and the drain pipe, special assemblies are necessary.
  • the connecting system for combining the drain water of the sink and the overflow water is particularly complicated in conventional sink assemblies by the need of special components having odd shapes. These can be produced only as cast parts, and the requirements of casting technology must likewise be taken into account if production costs are to be kept within reasonable limits.
  • overflow channels are to be employed as overflow drain devices, they must be formed and cast With the sink. These overflow channels are formed, in a similar manner as in the enamelled basin, by a trough-shaped channel externally mounted to the sink. This is diflicult to do from the standpoint of manufacture. Furthermore, with respect to the possibility of controlling the enamel layer, as well as keeping the same clean, the same difficulties and disadvantages are encountered as in steel-enamel basins. If no overflow channel is cast, then it is necessary to employ the disadvantageous special assemblies for draining the overflow water.
  • the invention is based on the problem of avoiding the disadvantages of the conventional drainage assemblies for sinks having an overflow device.
  • this assembly comprises a closed overflow vessel of synthetic material, of a flat cross-section, having openings therein for receiving a slotted drainage pipe and having a pipe boss for the overflow down pipe; in the region of the pipe boss, the vessel is adapted in its shape substantially to the cross section of the down pipe and continues into an annular chamber around the perforations for the pipe, which chamber surrounds the slotted region of the drainage pipe in the manner of a collar.
  • the flow cross-section of the overflow vessel that is, that cross-section perpendicular to the laminar flow, uniformly increases in going from the pipe boss to the slots in the drainage pipe.
  • uniformly is meant that there are never any discontinuous changes in cross-section. This is a very important feature, since such discontinuities cause clogging deposits.
  • the plastic material employed for producing the overflow vessel substantially repels dirt and impurities, a clogging of the overflow downpipe or the overflow vessel is hardly possible.
  • knees and constrictions of the cross-section along the passage from the overflow part in the sink to the drainage pipe are, in addition, substantially avoided.
  • the crosssection traversed by the overflow water increases constantly and uniformly in the direction toward the sink valve.
  • the suction effect created by this constant, uniform increase causes even rather large impurities to be entrained by the current, i.e., there is a continuous self-cleaning action of the overflow vessel.
  • the constancy of increase is especially advantageous when the bottom of the basin lies substantially in the horizontal plane, since the overflow vessel produces a suction effect even when snugly mounted against the bottom of the basin.
  • This invention is furthermore advantageous in this horizontal case, because its overflow vessel extends outwardly to where a vertical overflow downpipe can be connected.
  • the verticality of the downpipe produces a gravitationally caused suction, while the increasing cross-section of the overflow vessel creates a geometrically caused suction where esthetic and space requirements dictate that the overflow vessel should hug closely to the horizontal bottom of the vessel.
  • a special advantage of the structure of the present invention is that the junction between the overflow vessel and the drainage pipe, thus the slots of the drain pipe, can be cleaned without the necessity of dismantling.
  • the novel drainage assembly of the invention is also usable for basins made of ceramic material; the overflow channels formed previously in such basins, which extend in the interior of the basin wall and are known to be disadvantageous, are eliminated, so that thinner sink walls can be employed. Thereby, not only a substantial saving in material is attained, but the manufacture is likewise extraordinarily simplified, thus lowering the costs for ceramic sinks substantially.
  • the overflow vessel consists of a lower portion and a removable lid and that several reinforcing ribs are arranged on the circumference of the openings for the lower section of the drain pipe, at least one rib being provided between the drain pipe and the pipe boss for the downpipe.
  • This rib rests on a counter rib of the lid and has a streamlined cross-section in the direction of flow of the overflow water.
  • the invention furthermore provides that the pipe boss for the overflow downpipe is attached to and forms one component with the lid of the overflow vessel, and that the lid has a funnel-like depression around the passage opening, for receiving a conical seal placed against the top of the lid.
  • the invention furthermore provides that the pipe boss attached to the lid of the overflow vessel points upwardly and receives a plastic downpipe.
  • the plastic downpipe flares at its upper end and is closed off thereat by a removable cover. It is furthermore provided with at least one planar, reinforced side wall for junction with an overflow rosette insertable in the sink wall.
  • FIGURE 1 is an elevational section through the device of the invention and a basin to which it is attached.
  • FIGURE 2 is a top view of the overflow vessel of the invention.
  • FIGURE 3 is a front view of the upper part of the invention.
  • the device of the invention comprises an overflow vessel 1, an overflow downpipe 2 and a sink drainage pipe 3-.
  • the assembly shown here is used for a sink 4 made of steel or enamelled steel.
  • the overflow downpipe 2 is provided with a pocketlike flaring head 5 at its upper end, as shown in FIGURE 3; the wall of this head 5 is reinforced, at least one wall, namely the one on the side of the sink, being of planar construction.
  • the upper end of the head section 5 is closed by means of a clamping lid 6 which is mounted in a detachable manner.
  • An overflow rosette 8 is seal ingly inserted in the reinforced wall 7 with rosette abutting, via a seal 9, on the edge of the sink wall 4 which has a depression in the region of the overflow port.
  • the lower end of the overflow downpipe 2 preferably terminates in a sealed manner, if desired with the interposition of a seal, not shown, or also, in case it need not be disassembled, by means of cementing, in an intimate contact within pipe boss 10, this pipe boss being a portion of the overflow vessel 1.
  • the overflow vessel 1 is adapated with respect to its cross-section substantially to the cross-section of the downpipe 2, as shown in FIGURE 2.
  • the overflow vessel 1 is of a two-part construction and consists of a lid 11 and a lower portion 12.
  • the pipe boss 10 is provided in the lid 11.
  • the lid 11 is furthermore provided with a passage opening 13 for the drainage pipe 3; the passage opening 13 is surrounded by a conically depressed region 14 of the lid, so that a likewise conically shaped seal 15 can come in flush contact therewith.
  • a correspondingly conically formed portion of the sink 4 abuts on the seal 15. This bulging portion of the sink 4 surrounds the outlet opening for the pipe 3.
  • the drain pipe 3 is locked to the sink via a seal 16 by means of a flanged portion 17.
  • a tubular section 18 follows this flange-like portion 17, the section 18 being provided, within the overflow vessel 1, with lateral inlet slots 19 for the overflow water.
  • the tubular section 18 has a thread 20 to which a counternut or a sleeve 21 is attached which contacts, via seal 22, the underside of the lower wall 12 of the overflow vessel 1.
  • the clamping connection effected by tightening the tubular section 21 of a sewer pipe connection firmly holds together the two-piece overflow vessel 1 without any further measures being needed. At the same time, this connection creates the tight c'olnnection between the drainage pipe 3, the sink 4, and the overflow vessel 1.
  • a conical inner area 23 is provided in the tubular section 18, in the zone of the flange 17, this area serving for receiving a closing stopper or sealing cone.
  • the inlet slots 19 for the overflow water have such a large crosssection that they do not effect constriction of the current in the flow cross-section.
  • the overflow water flowing into the downpipe 2 through the rosete 8 is not subjected to any flow inhibition, constriction or bending when entering the overflow vessel, as can clearly be seen in FIGURE 2; rather, when the water enters the overflow vessel 1, it is subjected to a continuous increase in its flow cross-section up to the overflow slots 19, so that a suction eflect is encountered under Whose influence entrained dirt particles, impurities, etc., can likewise be safely discharged.
  • the slot area of the drain pipe is readily accessible for cleaning, for instance, by the insertion of a brush from above into the drainage pipe.
  • reinforcing ribs around the outlet opening 13 in the lid 11, opposed to a corresponding outlet opening 24 in the lower wall 12; at least the reinforcing rib 25a of these ribs, positioned between the outlet opening 24 and the connecting pipe 10, is provided with a streamlined crosssection and rests on counter rib 26 of the lid 11.
  • the material used for manufacturing the overflow vessel is plastic, preferably polypropylene, so that the overflow vessel 1 can also be chromium-plated after its manufacture, if this is desired. When chromium-plating this component, a unitary total impression is obtained, in conjunction with the drain trap which may also be chromium-plated and the chromium-plated sink valve 3.
  • the overflow downpipe 2 is made of the same plastic material.
  • Novel drainage assembly of the invention can be employed for all sinks having an overflow port.
  • a drainage and overflow device for connection to the bottom drainage opening and the overflow opening of a basin for containing liquid, comprising:
  • a drainage pipe means sealable to the bottom drainage opening of the basin to project substantially vertically downwardly from the basin;
  • an overflow vessel having in an upper wall a passage opening and in a lower wall an outlet opening, said passage and outlet openings being aligned, said overflow vessel being inserted over said drainage pipe means with said drainage pipe means extending from the basin, first through said passage opening and then through said outlet opening;
  • said drainage pipe means being slotted within said overflow vessel
  • a device as claimed in claim 2 said plastic being a chrome-coatable ABS (acrylonitrile-butadiene-styrene) plastic.
  • a device as claimed in claim 1 for connecting to the bottom drainage opening and the overflow opening of a basin having its bottom lying substantially in a horizontal plane when mounted, the overflow vessel extending substantially in the horizontal plane, with its upper wall being substantially horizontal and containing said passage opening and with its lower wall being substantilly horizontal and containing said outlet opening.
  • said overflow vessel having a substantially vertically extending pipe boss; said overflow downpipe being sealedly connected to said boss.
  • said overflow vessel surrounding said drainage pipe means annularly on the side of said drainage pipe opposite to the connection of said overflow downpipe.
  • a device as claimed in claim 1 further comprising means to connect said drainage pipe means to a sewer pipe; said drainage pipe means having a flange on its upper end; said flange being of a diameter larger than the inner diameter of the bottom drainage opening of the basin; said means to connect being operable to push on said lower wall in the direction toward said basin and pull on said drain pipe in the direction away from said basin; said overflow vessel having an internal reinforcing rib extending between said upper and lower walls and situated between said drainage pipe means and the junction of said overflow downpipe with said overflow vessel, said rib being streamlined to reduce friction to fluid flow.
  • a device as claimed in claim 10 further comprising resilient annular seals insertable around said drainage pipe and between said basin and the flange of said drainage pipe and between said basin and said upper wall of said overflow vessel; said means to connect forcing said flange and said upper wall into sealing contact with said annular seals.
