Description

In the sanitary engineering become sanitary items, like z. As washstands, bathtubs, toilets, showers and sinks i. a. above Single lines drained, which are merged into a collection outflow line.

are such sewers clogged, d. H. it will not be anymore full nominal waste water discharged, An aid is used to remove the blockage. A widely used pipe cleaner is the spiral, which is twisted out of or braided steel wires formed as a flexible shaft is. This is usually used in such a way that over one Access to the clogged pipe usually by dismantling the siphon the spiral is introduced and with it under Rotational motion as long as the plug is pushed until this is crushed and pushed through. The closure point is usually released suddenly and the pent-up wastewater can drain. The spiral is held with one hand, pushed and with the other hand by means of a crank in rotary motion.

This Procedure involves several disadvantages, because when the accumulated Wastewater is drained, the constriction is usually not yet Completely eliminated. For this reason, after piercing the Constipation with the spiral usually worked on for some time, remaining, fixed To dissolve particles. But since the water has already drained away, they will then still solving Particles are not immediately rinsed away. Thus, there is a danger that the affected area soon catches up again. Another disadvantage is that the spiral becomes heavily polluted and the user, though he pulls the spiral out of the sewage pipe, often the floor, Walls or surrounding objects dirty. Furthermore, the spiral is only awkward to clean after use.

The state of the art for this purpose is from the US 23 12 826 a pipe cleaning device with a sealable on a sewage pipe Abdichtglocke known in the means of an upstream, traversed by pressurized water spiral, a rotating and pulsating water flow is generated, which enters the sewage pipe. Furthermore, the describes DE 298 18 864 U1 a guided in a spiral pressure water hose, which is insertable into the beginning of a sewer pipe to eliminate obstruction by studs and flushing. This spiral is used primarily to protect the pressurized water hose. A rotation of the spiral for the mechanical elimination of blockages within the sewer pipe is not provided. Finally, that describes DE 82 32 917 U1 a flexible shaft which can be driven by a drain valve, for cleaning pressurized pipes. Furthermore, the describes DE 696 08 615 T2 a method of apparatus for cleaning pipes via an inserted lance by means of sound. Furthermore, the describes US 5 601 225 A a device for sealing pipes by means of hollow rings especially for welding preparation.

The inventive additional device provides a device available which makes working with a spiral much easier, with shorter working hours achieved a high cleaning effect and also by laymen easily and easy to use.

These The object is solved by the features of claim 1. advantageous Further developments are the subject of the dependent claims.

The inventive additional device is first placed on the access point on the sewer pipe and inserted to the tightness. Subsequently, a commercial spiral through a central opening the additional device into the front part of the clogged Sewer pipe introduced. The additional device is over a pressurized water hose connectable to a water tapping point and can over at least one opening Feed water into the blocked pipe. The water can here cleaning additives be mixed. Furthermore, it can be cold, warm or hot supplied become.

The pressurized water-loaded additional device sits firmly in the clamping seat in the sewer pipe, ie the user has both hands free. The area between the additional device and the pipe inner wall on the one hand and between the auxiliary device and the spiral on the other hand is basically sealed due to the application of pressurized water, but a complete seal between the additional device and the spiral for safety reasons, neither desired nor imperative, as Hereinafter: Conventional drainage systems are predominantly based on gravity, ie the wastewater is discharged via sloping lines. For such a system to work safely, enough air must always be available. To ensure this, the lines must not be completely filled and are therefore dimensioned for certain partial fill levels. Most are mainly in the siphon area pipe sections available, which are only plugged, so only loosely connected. Therefore, if an increased pressure is exerted on the system in a pipe cleaning, so there is a risk especially in arches that connectors are pressed apart and the system is leaking. An increased risk ko exists in particular in the application by laymen, who are unaware of this condition. Thus, a complete sealing of the access point mandatory absolutely not necessary, which is why the additional device according to the invention in this respect plays the function of overpressure protection. Moreover, since there is only a limited water leakage to the user out, there is little danger that this or the environment gets wet.

One An essential advantage of the invention is that when pulling out the spiral possibly adhering to the spiral dirt be stripped off, allowing the user to remove the blockage automatically has again a clean, operational spiral in hands.

Brief Description:

It demonstrate

1 an additional device according to the invention in the side view, without hidden edges,

2 the additional device with respect to the water outlet openings in detail, with hidden edges,

3 the additional device, which is located in the clogged tube, with spiral and tube sleeve in section,

4 the additional device in front view without tube sleeve.

The additional device consists of a flexible, but relatively stable material, eg. B. from a suitable rubber compound, and has an outer and an inner wall, which together form a hollow chamber ( 1 ) form. This has a substantially round, the sewer pipe ( 5 ) adapted cross-section, which is to the sewer pipe, ie in 3 tapered to the right. The additional device can thus be easily introduced into different pipe diameters, and must depending on the pipe inside diameter only more or less far into the sewage pipe ( 5 ) are inserted. For a better hold in the pipeline provide on the outside of the outer wall spaced, circumferential, flexible ribs ( 4 ).

The inner wall may be basically cylindrical in length, but preferably, as well as the outer wall, slightly tapered away from the user, whereby the insertion of the spiral ( 7 ) is facilitated.

At the user-facing rear side of the outer wall or laterally there is a connection ( 3 ) provided for a water hose. Through this flows after opening the associated water tap or an integrated valve, pressurized water ( 11 ) in the hollow chamber ( 1 ) one. At the front side, ie at the side facing away from the user, which is located inside the sewage pipe to be cleaned ( 5 ) is at least one outlet opening ( 8th ) for the water. Through this, the water flows continuously and possibly oscillating in the sewer pipe ( 5 ), wherein an overpressure in the hollow chamber ( 1 ), which creates the hollow chamber ( 1 ) presses sealingly against the pipe inner wall and their secure hold in the sewage pipe ( 5 ) guaranteed. At the same time, the inner wall of the hollow chamber ( 1 ) against the spiral ( 7 ), so that here is a seal and avoided that z. B. in a backwater of the water escapes uncontrollably and leads to damage.

By friction of the spiral ( 7 ) on the inner wall of the hollow chamber ( 1 ) this can be more stressed, which is why in the hollow chamber ( 1 ) one to the hollow chamber ( 1 ) adapted tube sleeve ( 6 ) is introduced as an exchangeable wearing part, which absorbs these frictional forces. The tube sleeve ( 6 ) is made of a suitable material and has an annular disc which sealingly at the front of the hollow chamber ( 1 ) is present. Now push water out of the sewage pipe ( 5 ), the annular disc is against the front of the hollow chamber ( 1 ) pressed while the gap between the tube sleeve ( 6 ) and the front of the additional device sealed. The tube sleeve ( 6 ) is manufactured in different inner diameters, so that by an appropriate replacement of the tubular sleeve ( 6 ) Different spiral diameters can be used.

The water outlet openings on the front side of the additional device are preferably formed so that a part to the outside, ie to the inside of the sewer pipe ( 5 ), and a part inwards, so are directed to the tube longitudinal axis. Preferably, the outlet openings are aligned inclined with a component in the circumferential direction, ie more or less obliquely to the tube longitudinal axis, whereby a cleaning effect increasing swirl of the water in the sewer pipe ( 5 ) is produced.

By this arrangement, the inner wall of the sewer pipe ( 5 ), as well as the spiral ( 7 ) and treated with water.

After exposure of the clogged point, the flow of water can be interrupted and the spiral ( 7 ), optionally with a suitable rotational movement, pulled out of the additional device and the Additional device with the hollow chamber ( 1 ) from the sewage pipe ( 5 ) are removed.
