Definitions

  • This invention is in particular related to drains or, traps outlets in floors of the kind that exist in for instance bath-rooms, wash-rooms etc.
  • the water trap or its connecting piping is unable to divert the water with the same speed that it for instance flows out of a bathtub or is pumped out of a washing machine. The result is that the water is retained on the floor surface, which i.a.
  • the floor drain of AT-B-366 128 does to a certain extent prevent the above problems since it is a floor drain with an additional connection and a non-return valve in the floor drain itself.
  • water from for instance a wash basin can be transported through the floor drain well and the its outlet without the risk of water flowing out on the floor since this is prevented by the non-return valve, as is of course back water from other parts of the house.
  • the valve will probably stick in the open position allowing a flow out onto the floor.
  • this device is limited in its use since in order to obtain the advantages at the location of an old drain one has to brake up the floor etc.for the exchange.
  • the primary object of the invention is not only to avoid the risk of flooding but also to prevent foul air and contaminations to pass the floor drain and it shall also be possible to use the insert in already existing floor outlets without braking up the floor.
  • the additional connection can include an extension that extend down into the housing or the well so that also for this connection a water trap is established.
  • a non-return valve in the shape of a seat and a sphere or ball can be arranged in this extension.
  • non-return valve and/or water trap for this additional connection for for instance bathtub, wash basin, wash machine etc, can be arranged at another location for instance in the case of the wash basin directly below this.
  • This later variety can for instance be suitable when an existing floor outlet installation with limited space possibilities is to be made more secure and hygenic in accordance with the invention.
  • the non-return valves prevents evaporation very efficiently and consequently the risk of foul air is diminished as from the outlet escaping unhealthy air in for instance intermittently used facilities as for instance hotel rooms, changeing rooms in shools etc.
  • a ground plastic ball is preferably used.
  • a water level of a few centimeters is sufficient to push down the ball so far into the water in the water trap that water can stream out through the floor outlet connection.
  • the floor outlet and the additional connection respectively can themselvels constitute parts of the water trap.
  • the floor outlet housing in some cases has an unremoveable water trap device, the water trap function of the floor outlet connection and the additional connection respectively are thus not necessary.
  • the reduced flow capacity due to the original water trap in series with the non-return valves can be compensated by for instance the lower end of the floor outlet connection being provided with wall parts that can be broken away but still guide the ball in the water trap but provides a more free water flow.
  • Fig 1 shows in cross-section an insert for floor outlets in accordance with the invention
  • fig 2 an installed floor outlet with insert
  • fig 3 a known floor outlet with the floor outlet insert according to the invention
  • fig 4 the insert of fig 3 seen from above
  • fig 5 the floor outlet of fig 3 and 4 seen from above without insert.
  • the floor outlet with insert shown in figs 1 and 2 includes a housing 29 located in the floor for connection to outlet tubing and sewer net. Between the floor outlet housing 29 and the sewer connection a wall or lip 32 extends from the bottom, to dam up water to a water trap.
  • a floor outlet insert is lowered that in its entirety is designated as 25.
  • An unsymmetrical funnel part 28 transcend into a cylindrical vertical tube piece 31 constituting,upper water trap lip.
  • a seating 34 for a ball 33 located below.
  • the level 30 of the water trap keeps the ball 33 up against the seating 34.
  • the specific weight of the ball 33 is however so chosen or adjusted, possibly by water being pumped into the ball that merely a water level of a few centimeters above the ball is capable of pushing this aside so that water easily can flow down through the water outlet.
  • a connecting hole 27 below which an extension 26 for a connection extends down to the same level as the vertical tube piece 31 so that also for this connection a water trap is obtained.
  • a connecting tubing 2 for for instance a wash basin can be connected.
  • the hole 27 can in fabricated, delivered status of the insert 25 be closed but provided with a fractural impression so that a disk corresponding to the hole 27 simply can simply be broken away or cut away. This for use at those floor outlets where this additional connection is not needed.
  • the seat 34 include a sealing ring for contact against the ball that preferably is ground.
  • This seal can for instance be of rubber.
  • the connecting hole 27 can include a rubber seal intended to secure absolute seal against the inserted connection tubing.
  • a seat for a non-return valve ball can be arranged in the water trap tube 26.
  • this seat can be constituted by the lower end of an inserted connection tubing, alternatively by a seat similar to that of the floor connection itself.
  • the water trap insert according to the invention can also be arranged in already existing floor outlets or drains, as is shown in figs 3-5.
  • the floor outlet housing 41 includes a connection 42 to the sewer net and a lower water trap lip 43 and an upper water trap lip 44.
  • the floor outlet On its upper side the floor outlet in a known way has a flange 45 for contact against a floor and a shoulder 46 in which a clamping ring 48 can be introduced to clamp the floor carpet or coating 46 and then the entire upper side of the floor outlet is covered by a grid 49.
  • a floor outlet insert in accordance with the invention.
  • This includes a collecting funnel part 50 that at its outer edge transcends into a flat flange.
  • the funnel part 50 slopes excentrically against a seat portion 51 below which a ground sphere or ball of plastic floats on the water level in the water trap.
  • a rubber seal 53 is arranged to increase tightness.
  • a water trap constituting and ball retaining and guiding extension 54 is arranged below the seat.
  • the funnel part 50, the seat 51 and the extension 54 are suitably integrated in one piece.
  • a stud pipe 55 or a so called “knock-out” (removable hole) is arranged extending upwards, to which an additional connection 56 has been connected, preferably with the insertion therebetween of a seal and that in the shown case extends a distance down into the floor drain or outlet but not down to water level due to the limited space of the well or housing.
  • the streaming of the water from the additional connection has schematicly has been shown with arrows.
  • the contact surface between the floor drain insert and the shoulder 46 of the floor drain is preferably sealed with a floating silicon seal or the like.
  • the tunnel 50 of the floor drain is intended in particular for secondary splash or rinsing water while the connection 56 is intended for primary water from a bath tub outlet or the like. In the same way as in the previous embodiment a small water pressure from the upper side is efficient to push aside the sphere or ball 52.
  • the invention reduce the overflow risk at stop in the outlet tubings, and. Prevent water from wash basin, wash machine or bath tub to pour out on the floor, which in turn also drastically reduces the risk of water entering below the floor coating or carpet. Furthermore the risk of smell and contamination forcing their way up through the outlet due to dried out water traps is reduced. Since the floor drain according to the invention essentially only differ from the floor drains of today by the shape and look of the insert the invention is also applicable in already installed floor drains or outlets, which considerably reduces the costs for an increased security against water damages.
