Flushable drain floor drain with non-return valve

The invention relates to a floor drain for use in various wet rooms 5, which has a non-return valve which can be connected to washing machines or similar devices and which is provided with a flushing connection. The floor drain of a sewer with a flushable non-return valve comprises a floor drain part with grilles acting as an odor trap, a removable non-return valve part and a flushing and washing machine connection part.

The use of a water trap in the floor drains of wet rooms has been a matter of course for those skilled in the art. However, as sewer technology began to develop, several patents were initially sought for various mechanical sewer shut-off devices. Such inventions include U.S. Patent Nos. 215,887, 216,238, 835,852, and 1,107,096. In the devices of the above publications, the drain plugs were either counterbalanced or shaped so that the water on them caused a torque to open the flap. The purpose of such solutions was to partially replace the current water formation. odor trap or prevent potential floodwater from entering, for example, basements.

25 Today, sewer floor drains are usually made of either plastic or cast iron. Floor drains are quite simple in construction and are usually provided with a partition wall to create an odor trap formed by water. However, the disadvantage of such devices is that they are difficult to clean in the event of clogging. If the current odor trap is clogged, it is cleaned either by pouring plenty of water into the drain odor trap and rinsing off any blockage in the drain, or by removing the grate on top of the floor drain and scraping the water. 94792 the waste that caused the blockage in the floor well. Also, the connection of a sewer of a washing machine or similar device to a floor drain is usually made by bringing the pipe radially to the side of the floor drain. In this case, the generally quite high flow rate in the outlets of the washing machines is not utilized in any way. In addition, the problem with sewer floor drains, especially in older buildings, is that different strains of microorganisms are generated in them. One such animal is the so-called. a sugar larva that thrives quite well in sewers and 10 uses the organic waste generated and attached to them for food. Naturally, the water trap floor drains currently in use do not, of course, block the passage of sugar larvae in the sewer.

The floor drain of a sewer with a flushable non-return valve according to the invention provides a decisive improvement over the above-mentioned drawbacks. The device according to the invention is characterized by what is stated in the following claims.

The most important advantages of the invention are its environmental friendliness, i.e. no solvent or disinfectant of any kind needs to be used in the device, but the cleaning and rinsing of the floor drain can be performed with clean water, and in addition the well is a so-called self-cleaning type.

. The passage of various larvae and other similar organisms through the floor well 25 is prevented by a removable non-return valve part. Due to its detachability, the non-return valve part can be removed from the floor drain and the mechanical flap can therefore be easily cleaned.

In the following, the invention will be explained in detail with reference to the accompanying drawings.

Figure 2 shows a top view of the floor drain according to Figure 1.

Figure 3 shows a cross-section of a floor drain with the drain connected tangentially to the floor drain.

Figure 4 shows a top view of the non-return valve part.

Figure 5 shows a side view of the non-return valve part.

Figure 6 shows a cross-section of the non-return valve part.

In Figures 1-6, the number 1 refers to the body-body portion 10 of the floor drain and the number 2 refers to the water odor trap. The number 3 indicates the drain pipe. Numeral 4 refers to a floor drain collecting funnel with a grate 5 on it. Numeral 6 denotes a ring duct to which washing machine water and rinsing water are led via connections 7 and 8.

15 Numeral 9 refers to an opening in the bottom of the annular channel 6 from which water is discharged into odor trap 2. Numeral 10 refers to a removable non-return valve. The sealing surface 11 seals the non-return valve part 10 against the surface of the floor drain supply cone 4. The side walls of the non-return valve part 10 si-20 are marked with the number 12 and the helical base with the number 13. The mechanically operated non-return valve 14 is hinged to the base 13 with hinges 15. The non-return valve frame 14 is not completely vertical but slightly inclined 25 under the influence of gravity.

The flush floor drain with a non-return valve according to the invention is used in the following manner. The solution model shown in Figure 1 with a U-tube type odor trap is suitable for houses and structures with sufficient space for this type of floor drain, this is the case, for example, in ground-based structural solutions. If the floor height is not sufficiently available, a structural solution similar to Fig. 3 can be used, which is lower than the solution shown in Fig. 1. The device according to the invention of Kek-35 operates in the same way as a floor well in a wet room 4,94792, in which the water odor trap is normally used. Instead, it is not necessary to remove the grate 5 to clean the floor drain according to the invention, but it is possible to clean the device by draining the rinsing water either through the washing machine-5 or, if the device is provided with a separate connection, through this. In the ring channel 6, the rinsing water or the sewage water from the washing machine is in a strong rotational motion and discharged through the slot 9 into the water-lock part 2 of the sewer. a strong vortex inside the body of the drain, and the drain does not cause a very large deceleration in the vortex due to its tangential position.

The manhole supply cone 4 is dimensioned in accordance with the standards, whereby a separate non-return valve part 10 can be placed either in the old manholes or in the device according to the invention. The separate non-return valve part is completely sealed to the walls of the supply cone by means of a sealing surface 11 and can be removed for cleaning if necessary. When water is poured into the floor drain, it collects outside the flap 14 due to the helical surface, and the pressure caused by the water opens the flap 14. When water has drained into the drain and no new water is supplied from the floor, the flap 14 closes by gravity. Since the separate non-return valve part 10 is tightly closed in the cone 4 by the action of its sealing surface 11 and the side walls 12, the only possible route for sugar larvae, for example, is to enter the room through the flap 14. However, since the flap 14 closes by gravity, there is no possibility for the larva to enter the room.

The flushable drainage manhole with a non-return valve according to the invention can, of course, be modified quite extensively by changing the basic structures. Thus, there are several different types of solutions for arranging a water odor trap than those presented in this application. The feed connections of the washing machine and any rinsing connections can be arranged differently from what has been done in the solution according to this application 5. The shape and structure of the ring channel 6 can also be solved in a different way than presented in this application. However, the use of the above solutions and modifications is within the scope of the invention of this application.
