Odor trap and drain flushing device

The odor trap and sewer flushing device opens and flushes the sewer to the sewer, mainly in connection with the odor trap, and the blockages and obstructions, including the walls, the distribution plate and the water connection.

Sewer blockages are a rather embarrassing problem. Greasy food waste as well as various fibrous products such as hair and fabric fibers easily cause blockages in sewer systems. Numerous methods and tools have been developed to open up such blockages. They have generally been either mechanical and / or have been accompanied by a water rinse. Air rinsing has also been used to open blockages in sewer pipes. 15 The most common method of opening a blockage is, of course, an iron-wire tax-like device that bends in a tubular cat. However, their use is impaired by the fact that you cannot see inside the pipe. You may also use this method to avoid the jam itself.

20 Various cleaning methods based on water jets are already known. Generally, in these methods, the bottom strainer is removed from the top of the washbasin drain and replaced with a water jet connection, one end of which is connected to the water tap.

25 A commonly used method is the so-called a drainage bear comprising a separate suction cup placed, for example, on the bottom drain of the washbasin, after which the suction cup is pumped back and forth, whereby the water in the drain flows back and forth as the pressure changes due to the pressure variation caused by the suction cup.

U.S. Patent No. 2,735,794 discloses a device comprising a flexible pipe along which cleaning water to be discharged into a sewer is passed to a nozzle body provided with tangential holes which provide a circular motion to the pipe to be cleaned, 2 92743 and so on. open up potential blockages. The method and device in question also have the possibility of feeding a washing liquid or solvent along a separate pipe for cleaning.

U.S. Patent No. 3,937,404 also includes a device having a flexible water hose and a nozzle body at one end, the other end of which is connected to a water supply network. In contrast to the device according to the previous US publication, this device additionally has a plug around a flexible hose 10, which closes the mouth of the drain pipe, for example at the bottom of a sink or the like. Because the drain is closed, the pressure in the water mains can be used to open the blockage. The flexible hose passes through the plug, and the nozzle can be transported in the drain pipe up to -15 back to open the blockage.

U.S. Patent Nos. 786,738, 406,977 and 798,713 disclose equipment solutions in which fixed nozzles are installed in connection with a drain pipe for clearing blockages. In these solutions, the water jet 20 is usually directed parallel to the pipe, whereby the cleaning effect is mainly based on the volume of water and the speed of the water jet. In general, it can be stated that the mechanical and water-jet-based equipment used has not had sufficient power.

* 25 The known devices and methods do not make full use of the power provided by the rotating movement, which can be used to clean the inner walls of the pipe.

The use of various chemicals and solvents has also become quite common in sewer cleaning. However, the applicability of these methods is hampered by the environmental disadvantages they cause, for example, for the treatment of waste water treatment plants. Myos ns. biological methods for cleaning sewers 35 have been developed. In methods based on the so-called bacterial cultures, 3,92743 bacterial cultures in a pasty state can be fed into the sewer. These bacterial strains have the ability to function and live anaerobically in an oxygen-free state. The weakness of bacterial-based methods 5 is that they are not tolerant to solvents but are destroyed.

With the odor trap according to the invention and the sewer flushing device, it is possible to open a blocked sewer with relatively little effort. The device according to the invention is characterized by what is set out below in the characterizing parts of the following claims.

The main advantage of the odor trap and the sewer flushing device according to the invention can be considered its ease of use. Most preferably, the device is placed before the odor trap 15 and connected to a hot water pipe. In this way, e.g. the advantage that greasy and other similar substances and combinations of substances can be flushed down the drain.

In current sewer systems in which plastic is used as the pipe material, the odor trap 20 according to the invention and the sewer flushing device are very simple to implement. In addition, the manufacturing cost of such a device is very low, and its placement in a sewer system does not incur very high costs.

. The odor trap and sewer flushing device according to the invention will now be explained with reference to the accompanying drawings.

Figure 1 shows an odor trap according to the invention and a sewer flushing device seen from the side with a U-tube placed in connection with the odor trap.

Figure 2 shows the device according to the invention in side view and partly in cross-section.

Figure 3 shows a device according to the invention in cross-section along the line I-I.

Figure 4 shows a cross-section along the line II-II.

Figure 5 shows a pipe to be connected to the underside of a device according to the invention, partially sectioned as seen from the side.

In Figures 1-5, the number 1 refers to an odor trap and a flush device. The side wall of the device according to the invention is marked with the number 2, the thread at the top of the device with the fastening number 3 and the mating surfaces with the number 4. The fastening takes place via a nut 5, and the tube 6 above the device according to the invention has a abutment surface 7 against the mating surface 4.

The rinsing water is fed to the odor trap and the sewer flushing device via a water supply connection 8, which is arranged tangentially to the device 15 according to the invention in order to improve the rotational movement. From the water supply connection 8, water is led to a channel 9 which is arranged annularly around the device according to the invention. From the channel 9, water is discharged into the pipe through the openings 10 through the distribution plate 11. The openings 10 are arranged tangentially to the distribution plate 11 and, in addition, extend in the direction of the rotational movement. By means of the flange 12, the device according to the invention is closed below the tube 13, which has abutment surfaces 15 as well as the surfaces 16 at the bottom of the device according to the invention.

The outer surface 14 and the constriction 17 of the distribution plate 11 are mounted against each other, whereby the openings 10 close from the outer circumference. At the other end of the U-tube 13 there are threads 18, and it is connected to the tube 19 via a nut 20, whereby the surfaces 16 and 21 press against each other.

The odor trap and drain flushing device according to the invention operates in the following manner. The water supply connection 8 is connected to the hot water network via a hose or pipe, and a shut-off valve is also installed in this space. When deficient water flow is detected in the vie-35 meter system.

5,92743, and it is expected that the sewer is clogging, the valve of the pipe leading to the water supply connection 8 is opened, and water is passed into the odor trap and the sewer flushing device. Water is fed tangentially into the channel 9, from which 5 further through the openings 10 tangentially inside the sewer pipes. Both the tangential position of the water connection 8 and the tangential arrangement of the openings 10 enhance the rotational movement. The efficiency of the odor trap and the sewer flushing device can, of course, be increased by feeding 10 volumes of soap solution or dishwashing detergent through the sink in connection with the flushing operation. In the tests carried out, it has been found that the vortex formed inside the sewer pipe is so strong that it still acts, for example, even after the U-pipe odor trap.

It is most advantageous to use the device according to the invention as a preventive device for maintaining the condition of a sewer.

It is natural that the odor trap according to the invention and the sewer flushing device can technically be implemented in several different ways, for example the duct 9 can be built closed, whereby its cleanability is reduced. The placement of the device according to the invention in the piping can also take place differently from that shown in the exemplary embodiment of the present application.
