Definitions

  • the present invention concerns a floor drain with a water trap and including an up-wards open outer bowl with one or more lateral inlets and one lateral outlet, in which is arranged an overflow plate; and with a abutment edge for supporting a grate for the floor drain.
  • Such floor drains are known e.g. for placing in wet rooms, such as bathrooms, where the inlets are connected with one or more wash basins.
  • the floor drains have functioned satisfactorily and have been used for incorporation in storey partitions and for embedding in floors.
  • a floor drain of this type is placed in relation to the surrounding surface with the abutment edge disposed under floor level, so that the grate of the floor drain will have an upper side which is at level with or slightly below level of the surrounding floor surface.
  • the abutment surface may be provided directly on the outer bowl, putting great demands on the tolerance accuracy with which the floor drain is placed in a storey partitioning or a floor.
  • the water trap will be provided by the interaction between an overflow plate which is arranged in the lower part of the outlet, and which interacts with an internal plate extending at the upper side of the outer bowl downwards with a lower edge at a position which is vertically below the level of the upper side of the overflow plate.
  • an overflow plate which is arranged in the lower part of the outlet, and which interacts with an internal plate extending at the upper side of the outer bowl downwards with a lower edge at a position which is vertically below the level of the upper side of the overflow plate.
  • the prior art floor drains are arranged with the grate disposed directly upon the outer bowl without any possibility of height adjustment. This is a drawback when a floor drain is to be applied and adapted to existing constructions. Furthermore, such a construction will render impossible the use of an existing floor drain if renovation is performed by laying an extra tile or vinyl on a floor where the drain is located.
  • the outlet is placed on an extended part of the outer bowl of the floor drain.
  • the downwards projecting plate will commonly be disposed with a downwards inclining projection, inwards towards the bottom of the outer bowl.
  • the overflow plate will be placed as a semicircular plate which is placed for covering approximately the lower half of a pipe connection that constitutes the lateral outlet.
  • this is achieved with a floor drain which is peculiar in that there is provided an inner bowl which is placed vertically displaceable in the outer bowl, as a packing is disposed there between, that the water trap is formed at the bottom of the outer bowl between a fixed, inclining plated projecting into the outer bowl and the overflow plate which is placed with an upper edge at a level located vertically above the level of a lower edge of a pipe connection projecting down into the outer bowl from the inner bowl, irrespectively of the vertical position of the inner bowl in the outer bowl, and that the overflow plate is disposed in the lower part of an outlet pipe connection and partially covers the outlet opening of the outer bowl.
  • An abutment edge which is provided at the upper part of the inner bowl, may hereby be disposed at correct floor level, whereby it becomes possible to re-adjust the position of the grate, irrespectively of the position of the outer bowl in a floor construction.
  • the water trap will be formed by the inclining plate and the overflow plate. With a water trap thus formed in the bottom of the outer bowl, water will always stand in the pipe connection by normal use. Hereby, there is a limited water surface compared with prior art floor drains, and there is no risk of smell nuisances from drain or sewage pipes.
  • the overflow plate is disposed in the outlet pipe connection itself, and is not a part of the outer bowl, it becomes possible to get sufficiently large flow area ensuring that the floor drain can drain off large momentary amounts of water, but simultaneously be made with a limited shape.
  • the outer bowl itself for establishing flow area.
  • a part of the volume in the outlet pipe connection for forming flow area in the water trap of the floor drain.
  • a particularly simple embodiment is peculiar in that the outer bowl is largely rectangular or cylindric and has a circular upwards directed opening for receiving the inner bowl or the pipe connection of the inner bowl, and that inlet and outlet are formed of largely cylindric pipe connections which are mounted directly on the circumferential surface of the outer bowl.
  • the outer bowl will preferably be formed with a circular opening and a circular packing that fit together with an inner bowl having circular shape.
  • the displaceable outer and inner bowl may be provided with other cross-sections, when it is possible just to perform vertical displacement with a packing disposed there between for establishing a sealing abutment preventing water from penetrating out between the inner bowl and the outer bowl.
  • the pipe connection of the inner bowl engaging the packing will have a constant cross-section over a first part immediately under an abutment surface for the grate. It is preferred that the lower part of the pipe connection has an inwards decreasing flow area, e.g. with a frustrated cone cross-section which either extends rectilinearly or is convergently or divergently tapering.
  • the inner bowl can be made with an upper tubular pipe connection and a lower tubular pipe connection fitted therein with lesser diameter.
  • the cross-sectional area in the lower part of the pipe connection will hereby become considerably less than the cross-sectional area in the upper part of the pipe connection at the top of the inner bowl.
  • the area may be between 20 and 80% of the cross-sectional area of the inner bowl, whereby the open water surface in the pipe connection is considerably reduced so that the risk of evaporation is minimised.
  • the bottom of the outer bowl will slope downwards towards the outlet.
  • the lower edge of the pipe connection of the inner bowl will be placed at a level which is between the lower part of the bottom and the upper part of the bottom.
  • the inclining plate is disposed in the outer bowl at a position in front of the outlet opening, extending obliquely downwards and inwards from a position above the outlet opening and having a lower edge at a position shortly above the lower part of the bottom.
  • a slotted passage is formed between the bottom and the lower edge of the inclining plate, enhancing liquid flow through the floor drain. A cleansing effect and simultaneously the possibility for the floor drain removing a large liquid flow are achieved.
  • the packing formed between the outer bowl and the inner bowl will be placed in a groove in the outer bowl which partially overlaps the upper part of the lateral inlet of the outer bowl.
  • the connecting pipes of the inlets will normally not have such character that the inlets are entirely filled with liquid, it will not be detrimental for the capacity of the floor drain that the upper part is covered by the packing.
  • floor drains with standard sizes for the inlet pipe connections without needing to increase the overall height with a height corresponding to the groove used for accommodating the packing.
  • the floor drain is peculiar in that the inner bowl at its upper side includes the abutment edge for the grate which is fastened by screws to the inner bowl.
  • the floor drain is peculiar in that the vertical distance between the levels of the upper edge of the overflow plate and the lower edge of the inclining plate is at least 50 mm and preferably between 50 and 80 mm.
  • the overflow plate has its upper edge placed approximately at a horizontal centre plane for the outlet connecting pipe. In this way, the needed height on the water trap is established in a floor drain with small height.
  • Fig. 1 shows a prior art floor drain 1 which is formed by an outer bowl 2 having an upwards directed opening 3.
  • the opening 3 is covered by a grate 4 which is loosely provided upon an annular abutment edge 5 at the upper circumferential edge of the outer bowl 2.
  • the outer bowl is provided with inlets 6 including tubular inlet pipe connections 7 which are mounted on the sidewall of the outer bowl at a position over a level 8 for water 9 standing in a water trap 10 which is provided in the bottom of the floor drain.
  • a part of the sidewall forms an overflow plate 11.
  • the upper side edge 12 of the overflow plate defines the level 8 for the water surface.
  • An inclining plate 13 extends from the upper side of the outer bowl obliquely downwards and into the outer bowl for forming a through-flow channel 14. Between the lower edge 15 of the inclining plate 13 and a lower bottom 16 in the outer bowl, a slotted passage 17 is formed, extending over the width of the outer bowl.
  • the level 8 for the water surface is located at a position below the inlets 6 and the inlet pipe connections 7.
  • the inlet pipe connections 7 are disposed with spacing from an upper edge 18 on the outer bowl.
  • the drain bowl is furthermore provided with an outlet 19.
  • the outlet 19 includes an extended part 20 at the side of the outer bowl.
  • An outlet pipe connection 21 is mounted on the extension 20 for connection to a drain pipe.
  • Fig. 2 the floor drain is provided with three inlet pipe connections 7 and an outlet pipe connection 21. Furthermore, it is seen that the floor drain is made with rectangular shape and is covered by a rectangular grate 4.
  • a floor drain 22 according to the invention.
  • An inlet pipe connection 7 is illustrated, which is connected with an inlet pipe 23 which, for example, is connected with the waste pipe from a wash basin.
  • the outlet pipe connection 21 is connected with a drain pipe 24 leading to the sewer.
  • an inner bowl 25 there is provided an inner bowl 25. Between the inner bowl and the outer bowl there is provided a packing 26 enabling vertical displacement of the inner bowl 25 in relation to the outer bowl 2.
  • the grate 4 may be fastened to the inner bowl 25 by means of screws 27.
  • the inner bowl 25 includes a tubular pipe connection 28 and, at its lower end, a tubular pipe connection 29 with smaller diameter than the tubular pipe connection 28.
  • the lower tubular pipe connection is terminated by a lower edge 30. This lower edge 30 is placed at a level which is below the level of the upper edge 12 for the overflow plate 11.
  • the overflow plate 11 is placed in the drain pipe connection 21 and extends to a position immediately above a centre plane 31 through the drain pipe connection 21. It is seen that the lower edge 30 of the inner bowl pipe connection will be situated at a level below the water level 8.
  • the water surface designated by 32 will be open to the ambient surroundings via the grate 4 of the floor drain.
  • the area of the water surface 32 will be less than the area of the water surface laid free in the prior art floor drain according to Fig. 1.
  • the inlet pipe connections 7 are disposed close to the upper edge 18 of the outer bowl 2.
  • the packing 26, which is disposed in a groove within the outer bowl, will thus be placed in a position that partly covers the upper part of the laterally directed inlets 6.
  • the overflow plate 11 is disposed in the lower part of the outlet pipe connection 21 and partly covers the outlet opening 33 of the outer bowl.
  • a weld 34 illustrates the position of the overflow plate 11 inside the outlet pipe connection 21.
  • Fig. 7 corresponds essentially to Fig. 2 and shows that the floor drain according to the invention is provided with three inlet pipe connections 7 and an outlet pipe connection 21 and is designed with a rectangular cross-section which is covered by a rectangular grate 4.
  • the grate 4 will, however, as distinguished from the embodiment shown in Fig. 2, be provided vertically displacing, so that it can be placed at a level which is adapted to the surrounding floor surface 35 (see Fig. 3).
  • Figs. 8 and 9 shown alternative embodiments of the floor drain according to the invention.
  • the floor drain in Fig. 8 has a circular grate 4.
  • the circular grate 4 is placed on the circular abutment edge 5 at the upper end of the inner bowl 25.
  • FIG. 9 illustrates a four-sided grate 4 which is disposed over an outer bowl having a circular upper circumferential edge.
  • the grate 4 is placed on an inner bowl (not shown) provided vertically displacing in the outer bowl 2, and which has an abutment edge (not shown) for supporting the grate 4.
  • circular flanges 36 are shown, intended for connecting the floor drain to a floor membrane, e.g. a floor vinyl.
