Definitions

  • Floor drains are known in many shapes since long time back and are for instance used in laundry rooms, bathrooms, shower spaces etc for the draining of water that intentionally or unintentionally gets on the floor. A regretfully normally unavoidable consequence of floor drains is however damages due to damp in surrounding floor and connected supporting structures. It is not enough with the moisture damaging the building but mildew may easily occur resulting in allergy problems. Many floor drains also result in bad smell.
  • the invention has as its object to cure the above problems with a floor drain that is not marred by the above failings. On accordance with the invention this object is solved with a floor drain insert in accordance with patent claim 1.
  • FIG. 1 shows a cross section through a floor drain insert
  • fig. 2 the bottom part of the same floor drain seen from above
  • fig. 3 and fig. 4 are analogous with fig. 1 and 2 but with an alternative arrangement of the parts and fig. 5 and 6 a water trap bowl for arrangement in the floor drain seen from above and in section respectively
  • fig. 7 a fixing detail for the drain
  • fig. 8 the inner parts of the drain in a cooperating position corresponding to fig. 3 and 4
  • fig. 9 a variety of a complete floor drain according to the invention
  • fig. 10 - 12 the fixing of the parts of the drain to each other in perspective, crossection and seen straight from above respectively
  • fig 13 an alternative detail in the drain.
  • the floor drain shown in fig. 8 includes a water trap bowl 18 that is shown in detail in fig. 5 and 6.
  • the bowl is essentially round with a central locating hole 22 in the bottom intended for cooperation with a pin in the bottom of the floor drain housing. Over a part of its circumference the outer wall of the bowl is however drawn in (14 and 21 in fig. 5 and 6).
  • the inlet part 1 of the floor drain includes as is apparent from fig. 1 a circular outer edge 2 for sealing against floor mat and floor drain housing respectively and a funnel part 4 going inwards and downwards from this and passing into a circular neck part 7 provided with a flange 6 on which a sealing ring 25 of rubber is arranged with an inwards extending lip.
  • the inlet part downwards passes into a cylindrical part 5 in which a ball 26 is arranged.
  • the ball 26 that floats in the water constitutes together with the sealing ring 25 a nonreturn valve preventing water from flowing up out of the floor drain and out on the floor.
  • the ball 26 has a slightly uneven surface, for instance achieved by grinding resulting in a water transport up from the water surface in the bowl to the sealing lip. In this way the contact surface is constantly kept moist and thereby leakproof. Through this bad smell is efficiently prevented from rising up through the nonreturn valve and further the ball is prevented from adhering to the seat.
  • the inlet part is further next to the eccentric inlet funnel 4 provided with an additional pipe socket like connection 9 for connection to other units as for instance wash basins, dish basins etc.
  • the connection 9 changes on the bottom side of the inlet part 1 into a pipe socket that is provided with a slot 11. This slot grips over the upper edge 14 on the indrawn part 21 of the wall of the bowl 18.
  • the major part of the crossection of the pipe socket 10 lies outside the bowl 18 and leads thus directly to the outlet 13 of the drain. Through this the flow will become essentially unhindered at the same time as a smaller amount of water always will flow into the bowl securing that a sufficient water level exist for sealing with the ball 26. Since water in a vertical pipe normally tends to spread out over the circumference the distribution between bowl and outlet is essentially independent of how large the total amount of water is.
  • the edge 14 is somewhat lower than the rest of the edge 20 of the bowl so that water from the floor (or from the additional connection) always flows out of the bowl precisely at the outlet 13 of the floor drain.
  • the slot 11 gripping over the edge 14 the angular position of the bowl is fixed by the inlet part 1 , the fixing of which will be described in more detail below.
  • the above described arrangement of the floor drain is suited for units provided with water traps of their own preventing the rising of bad smell.
  • the inlet part is instead turned in relation to the bowl 18 and the not shown floor drain housing so that the inlet 9 instead is placed as is shown in fig. 9 that is completely inside the bowl 18.
  • the inlet 9 has here been extended downwards as is apparent from fig. 3 with an extension 16 that has been inserted into the downwards protruding pipe socket 10.
  • An outer clamping ring 31 pushed on from below locks the extension 16.
  • the extension 16 extends as far down as the inlet pipe 5 for the floor inlet.
  • a water trap effect is hereby achieved for the connection 9 at the same time as there is no risk that for instance bath water should flow out on the floor. Not even other in this way connected units as for instance wash basins, dish basins etc need to have water traps of there own.
  • the wall 17 also has the function to prevent the bowl from turning from the shown position with the indrawn part and the overflow edge 14 turned against the outlet.
  • the indrawn part can be made unsymmetric with an extension away from the wall 17 to secure a sufficient flow crossection for water from the floor. If it should be desired one can even consider that several outlet units are arranged via a common floor drain provided with several extra connections.
  • a floor drain is obtained that always is ready to function as a floor drain but without the floor unnecessarily having to be burdened with water discharges, and also without risk of back flowing sewer water or sewer smell.
  • fig 12 In fig 12 is shown how a clamping ring 35 by means of screws 41 is fixable to the floor drain housing 36 for the clamping of the floor covering .
  • a shelf 44 is arranged for taking the insert.
  • the insert is held in place by a yoke 32 (se fig 7) that in its ends is provided with recesses 34 through which two diametrically situated screws 41 extends as is shown in fig 10 and 11. In this way the floor drain can cope with very large pressures from below without leaking.
  • a nonreturn valve comprising a from below inserteable pipe 117 that in the upper end is ended by a bellow like part 126 that on one hand constitutes a seat for a ball 124 and on the other hand a seal against the pipe into which it is inserted.
  • a bead or flange 122 is arranged on the outside to prevent the outpressing of the nonreturn valve.
  • This type of nonreturn valve can be arranged in the floor inlet of the floor drain as well as in an additional inlet.

Abstract

L'invention concerne un drain à insérer dans le sol, dont le fond comporte un bac et qui comprend une arrivée s'étendant depuis le haut vers le bas pour récupérer l'eau s'écoulant sur le sol, avec un clapet antiretour comprenant une boule et un siège. Une entrée supplémentaire s'étend dans la partie en entonnoir de l'arrivée et se termine en dessous de cette partie à une certaine distance à l'intérieur du bac. Le bac a un écran ou une paroi dont la position est inférieure à celle de la bordure du bac, délimitant ainsi une zone où il est possible d'aménager le raccordement supplémentaire pour faire en sorte que l'eau provenant de ce raccordement et en particulier les résidus de graisses remontent à la surface et ne descendent pas dans l'arrivée du drain. Cette arrivée est rotative par rapport au bac, si bien que le raccordement supplémentaire peut être saillant vers le bas dans la zone délimitée par l'écran ou la paroi ou bien être placé de manière à se terminer au-dessus du bord inséré du bac, de sorte que l'eau empruntant ensuite ce chemin s'écoule en partie directement dans la sortie du drain et en partie dans le bac du drain.
