Definitions

  • the present invention relates to a WC suite. More particularly, the present invention relates to an improved WC suite which reduces trickles after a flush.
  • the flushing system of such WC suites may e.g. be designed to allow flushing water to enter the bowl by gravity by arranging a flushing cistern at a level vertically above a water outlet connected to the WC bowl.
  • the flushing cistern contains a certain volume of flushing water, which is at least partially emptied when a user initiates a flush.
  • the flushing water flows from the cistern out through an outlet valve, and into the WC bowl via a flow path inside the WC suite.
  • the interior areas may be constructed in very specific manner due to the complex manufacturing techniques used.
  • the flow path extending from the outlet valve of the water cistern to the inlet of the WC bowl is tilted downwards.
  • a rim or other flow distributor provided for forcing the flushing water to flow along the entire inner surface of the WC bowl.
  • a small amount of water will however hit the rim (or other flow distributor device), and bounce backwards. The backflow of water will consequently follow the flow path between the inlet of the WC bowl and the outlet of the cistern.
  • the backflow of water will not flow all the way back to the cistern, but it will instead accumulate in a small compartment arranged inside the WC suite behind the cistern outlet, being in fluid communication only with the flow path extending from the cistern outlet and the inlet of the WC bowl.
  • This small compartment is commonly denoted as the flush box.
  • the problem of dripping water may be at least partly reduced in prior art system by using a water distributor arranged under the rim of the WC suit.
  • a water distributor arranged under the rim of the WC suit.
  • such water distributors are not desirable due to for example the design of the toilet or due to cleaning and hygiene aspects.
  • the present invention preferably seeks to mitigate or eliminate one or more of the above-identified deficiencies in the art singly or in any combination and solves at least the above mentioned problems by providing an improved WC suite.
  • a flushing system 10 for flushing water into a WC bowl 40 of a WC suit 100 is shown.
  • the flushing system 10 is constructed to allow a user of an associated WC suit 100 to flush the toilet after use, and for this purpose the flushing system 10, and hence the WC suite 100, includes a water cistern 20 and a flushing mechanism 30.
  • the water cistern 20 is in fluid communication with the WC bowl 40 by means of an outlet 12 being controlled to open by means of the flushing mechanism 30.
  • the water cistern 20 is capable of storing water between flushes and is in fluid communication with the WC bowl 40 by means of the outlet 12 being controlled to open by means of the flushing mechanism 30.
  • the flushing mechanism 30 is constructed to open and close the outlet 12 when the user operates a flush initiation means, such as a push button 32 arranged at the upper end of the water cistern 20.
  • a flush initiation means such as a push button 32 arranged at the upper end of the water cistern 20.
  • the outlet 12 When pressing the flush button 32, the outlet 12 will open, i.e. it will be in fluid communication with the water cistern 20, to allow the water enclosed within the water cistern 20 to drain out from the outlet 12 and into the WC bowl 40.
  • the water After passing the outlet 12, the water will pass through a flow path 14 which guides the flushing water through an opening 42 leading into the WC bowl 40.
  • the flow path 14 extends between the outlet 12 of the water cistern 20 and an inlet 48 of the WC bowl 40.
  • the WC bowl 40 is constructed with a bend 44 creating an integrated water trap in order to eliminate or at least reduce odours gases that are allowed to flow from a sewer pipe 46, into the WC bowl 40 and further into the surrounding bathroom. After the flushing water has passed the bend 44, the water is led out from the WC bowl 40 into the sewer pipe 46.
  • the flush box 50 is an enclosure, or compartment, where water will accumulate during flushes.
  • the inventors of the present invention have realized, after inventive and insightful reasoning that by arranging a water trap 56 in the flush box 50 and arranging the flush box 50 to be in fluid communication with the sewer pipe 46 the above mentioned problems will be greatly reduced. Instead of having water trickling for several minutes, the water dropping has now been reduced to merely a few seconds. The reduction of the amount of water trickling thus greatly reduces the risks of stains in the toilet bowl 40.
  • the flush box 50 comprises two opposite side walls 58, 59 and one bottom surface 57 forming an enclosure. It should be realized that additional side walls are also provided, however they are not shown.
  • the flush box 50 further comprises a dividing wall 52 which extends downwards into the flush box 50, but not entirely to the bottom of the flush box 50.
  • the dividing wall 52 forms part of the water trap 56.
  • the water trap 56 may thus be in the form of a U-bend or N-shaped structure, formed by the side walls 58, 59, the bottom surface 57 as well as the dividing wall 52.
  • the height of the water enclosed in the water trap 56 may be between 30 and 70 mm, and more preferably around 50 mm.
  • the height of the enclosed water is determined by the height of the two side walls 58, 59 and should be chosen to cope with standardised regulations.
  • an orifice 54 is arranged in order to connect the flush box 40 to the sewer pipe 46.
  • the flush box 50 is thus in direct fluid communication with the sewer pipe 46 by means of the orifice 54.
  • the flush box 50 is aligned with the sewer pipe 46 along a vertical line, so that when the flush box 50 fills up during a flush, the water will flow through the orifice 54 vertically down towards the sewer pipe 46.
  • the flush box 50 and its water trap 56 are preferably constructed by ceramic or other durable materials. In one embodiment the flush box 50 and the WC bowl 40 are constructed by the same material. The flush box 50 and its water trap 56 may be an integrated structure with the rest of the WC bowl 40. The water trap 56 is thus formed simultaneously with the rest of the WC bowl 40 which greatly reduces manufacturing costs.
  • Fig. 3a shows an exemplified situation where the water trap 56 of the flush box 50 starts to fill up with water just after a flush has occurred.
  • the water which bounces at the inlet 48 of the WC bowl 40 will be lead into the flow path 14 leading to the flush box 50 and the water trap 56.
  • the flow path 14 is tilted so as to guide the water towards the water trap 56. This restricts the direction of the water flow after a flush.
  • the inlet 48 of the WC bowl 40 is arranged at a higher level compared to the flush box 50, which creates a tilted flow path 14.
  • the flow path 14 is tilted so that the highest point is arranged near the inlet 48 of the WC bowl 40 and the lowest point is arranged near the water trap 56 of the flush box 50.
  • the flow path 14 is thus tilted upwards. The flushing water will flow in a direction downwards, while bouncing back from the inlet 48 towards the flush box 50.
  • Fig. 3b shows the situation where the flush box 50 is fully filed with water.
  • the remaining water in the flush box 50 will flow out through the orifice 54 down towards the sewer pipe 46.
  • the water will thus not be dripping on the toilet bowl, but will instead be lead through the water trap 56 into the sewer pipe 46.
  • the WC suits 100 shown in Fig. 1-3 are of a rimless design i.e. the inlet 48 of the WC bowl 40 is not a rim.
  • the inlet 48, or flow distributor device may be a single lip. The lip is arranged at the back of the upper part of the toilet bowl 40 and releases the flushing water from the cistern 20 into the WC bowl 40.
  • a flow distributor device such as a rim.
  • the WC suit 100 is of a rimless design. Having a rimless design eliminates the possibility to arrange a water distributor in the WC suite 100 (since it normally is arranged under the rim of the WC suit 100) in order to reduce the problems of water trickles. The present invention is thus particularly useful for toilets being of a rimless design.
