Description

The invention relates to an odor trap according to claim 1.

A variety of odor traps is known to prevent the escape of gases from a drain or a sewage pipe as possible. In some odor traps, the flow opening for liquids, in particular for wastewater, is opened or closed by a closing body. Wastewater often also contains dissolved or floating solids. A problem with previously known odor closures with closing bodies is that solids can be deposited which themselves can cause odor nuisance and can impair the functional capability of the odor trap. It is also problematic that due to deposits or accumulations of solids, the drainage properties of the odor trap are worsened or even clogged.

The invention is based on the object, an odor trap comprising a closing body for closing a flow opening of a drain body for liquids, in particular for wastewater, show, in which a deposition of solids contained in the liquid is largely avoided.

This object is achieved by an odor trap according to claim 1.

In particular, the object is achieved by an odor trap comprising a closing body for closing a flow opening of a drain body for liquids, in particular for wastewater, wherein the closing body of a flow opening at least partially releasing release position is disposed in a flow opening closing position closing and vice versa movably in the drain body in that the closing body can be moved from the release position to the closed position by means of mutually repelling magnets, and wherein the closing body has a curved or conical-shaped closing body surface which is so steep that substantially no solids contained in the liquid can deposit on the closing body surface.

One advantage of this is that substantially no solids contained in the liquid can be deposited in the odor trap or on the closing body. Thus, an odor nuisance by deposited solids is largely avoided. This also largely prevents impairment of the functionality of the odor trap. In addition, the maintenance of the odor trap decreases. In addition, an impairment of the drainage properties of the odor trap is largely avoided.

The closing body surface may be curved in such a way that at least one upper part of the closing body surface, in particular the entire closing body surface, is curved in such a way that the radius of curvature is at most approximately 50 mm, in particular at most approximately 35 mm. As a result, a deposition of solids contained in the liquid is still largely avoided.

In one embodiment, the odor trap is a pot-free odor trap. An advantage of this is that odor nuisance can be avoided even more safely because there is no pot in which solids that may be present in the liquid can be deposited. In addition, the cleaning of the odor trap is technically easier. The risk of clogging of the odor trap, in particular by deposited or accumulated solids is thereby substantially avoided or greatly reduced.

In a further embodiment, the drain body has a sealing body, in particular a sealing ring, which is arranged such that the closing body rests in the closed position on the sealing body. As a result, it is largely prevented that, while the flow opening of the odor trap is closed, exhaust gases from the waste water and / or the sewer through the odor trap ascend or the odor trap, in particular the closing body, can happen.

In a further embodiment, the drain body, in particular in a region between the release position and the closing position of the closing body, has such a curved inner surface that substantially no solids contained in the liquid can deposit on the inner surface. As a result, it is largely avoided that solids can be deposited on the inner surface of the drain body. The advantage of this is that odor nuisance can be avoided even more safely. In addition, the odor trap has a self-cleaning effect or the self-cleaning effect of the odor trap is improved. In addition, this largely ensures that the drainage properties of the odor trap are not affected by depositing solids.

At least one upper part of the closing body can essentially have the shape of a, in particular straight, cone, preferably a circular cone, exhibit. As a result, the production of the odor trap is technically easier.

In a further embodiment, the closing body at least partially substantially in the form of a rotationally symmetrical about the vertical axis in use geometric body. This reduces the production costs for the odor trap. In addition, a uniform flow through the drain body is guaranteed.

In a further embodiment, at least a portion of the mutually repelling magnets are permanent magnets. This reduces the operating costs and the operating costs. In addition, the production costs are reduced.

At least part of the permanent magnets can be arranged on the closing body and / or in the closing body. An advantage of this is that the odor trap is technically easier.

At least part of the permanent magnets can be arranged in the drain body and / or on the drain body. An advantage of this is that the odor trap is technically easier.

In another embodiment, at least a portion of the mutually repelling magnets are electromagnets. This reduces the production costs and the susceptibility of the odor trap to failure. It requires a smaller number of moving elements, since electromagnets can be switched on and off in contrast to permanent magnets. By turning on and off the electromagnets of the closing body can be moved from the closed position to the release position.

At least a portion of the electromagnets may be arranged in the drain body and / or on the drain body. As a result, a simple wiring of at least a portion of the electromagnets is made possible.

In a further embodiment, the mutually repelling magnets are at least partially, in particular completely, encased in such a way that the liquid substantially does not come into contact with the magnet. This prevents solids from settling around the magnets. This is on the one hand unhygienic and on the other leads to unpleasant odors. In addition, a functional impairment of the odor trap is essentially prevented by solids depositing on the magnet. Thus, an odor nuisance is effectively avoided by any deposits in the area of the magnets. Consequently, the maintenance and cleaning costs are also reduced.

A probe can be arranged in the drain body for monitoring the liquid level above the closing body, wherein the probe can move the closing body, in particular by its own weight, from the closed position to the release position as soon as the liquid level has reached or exceeded a predetermined value. As a result, the odor trap can automatically control a drainage of wastewater. The odor trap opens only when enough liquid has accumulated above the closing body.

Too frequent opening of the flow opening of the odor trap or the closing body is thus avoided. This reduces the workload and leakage of odors is even better avoided.

In another embodiment, the repulsive force between the mutually repelling magnets is set at a predetermined distance between them such that, as soon as the liquid level above the closing body has reached or exceeded a predetermined value, the closing body moves against the repulsive force from the closed position. Once a fixed amount of liquid is above the closing body, thereby the flow opening is released, whereby the liquid can flow through the odor trap. An advantage of this is that the odor trap is technically simple, since no active control of the opening or closing of the odor trap or the flow opening is necessary. This reduces the operating costs and the operating costs.

In 1 is the closing body 20 in the release position. Wastewater or liquid flows through the flow opening 80 and over the closing body surface 25 ,

The closing body 20 or the closing body surface 25 has a flow opening 22 on that in 1 is arranged decentralized to the closing body center. The liquid or wastewater flows through the flow opening 22 when the closing body 20 in the release position. Thus, the water in the release position the odor trap 1 flow through and drain.

2 shows a side / cross-sectional view of the embodiment of the 1 , wherein the closing body 20 in one the flow opening 80 closing closing position is. In the closed position is the closing body 20 or the closing body surface 25 at least partially on a sealing body, in particular a sealing ring 50 , at. The sealing body may also have other shapes, for example rectangular or elliptical. The sealing body is preferably made of a flexible material. The closing body 20 or the closing body surface 25 has a shape corresponding to the sealing body, so that the closing body 20 in the closed position, the flow opening 80 completely closes.

In the closed position, no sewage between the sealing ring 50 and the closing body surface 25 flow through. In this closed position is a drainage of waste water through the odor trap 1 prevented. At the same time an increase of odors from the drain or the sewer, with the drain body 10 connected, prevented.

In the closed position is a part of the closing body 20 continue between the protrusions 12 . 12 ' of the drain body 10 , A small part of the closing body 20 that is the tip of the closing body 20 includes, stands over the sealing ring 50 upwards.

The movement of the closing body 20 from the in 1 shown release position in the in 2 shown closing position is by mutually repelling magnets 30 . 40 reached. The mutually repulsive magnets 30 . 40 move the closing body 20 from the lower release position (in 1 shown) in the higher closed position (in 2 shown) and hold the closing body 20 in the closed position. If that in the protrusions 12 . 12 ' of the drain body 10 arranged magnets 30 Permanent magnets are, the magnets are 30 in the drain body 10 so in relation to the magnets 40 of the closing body 20 arranged that the poles of the magnets 30 . 40 repel each other. As a result, the closing body 20 to the sealing ring 50 or sealing body pressed.

If the magnets 30 in the projections 12 . 12 ' of the drain body 10 Electromagnets are, these can be switched on or off. If the magnets 30 be turned on so that the magnets 30 of the drain body from the magnets 40 in the closing body 20 repel, becomes the closing body 20 also moved from the release position to the closed position. Once the electromagnets 30 are turned off, the closing body moves 20 by its own weight from the closed position to the release position. This movement can be assisted by the electromagnets 30 be reversed so that the magnets 40 in the closing body 20 and the magnets 40 in the drain body 10 attract.

The sealing ring 50 runs slightly diagonally downwards from the outside inwards.

In 4 is a probe 60 in the drain body 10 arranged. The probe 60 monitors the liquid level above the closing body 20 , That means the probe 60 the height H of the liquid level above the sealing ring 50 supervised. Once the liquid level 70 the probe 60 reached and thus the liquid level has reached the value H, the probe switches 60 the electromagnets 30 of the drain body 10 from. By the weight of the closing body 20 and the weight of the liquid acting on the closing body 20 presses, the closing body moves 20 from the closed position to the release position. This movement can be further supported by the fact that the electromagnets 30 not turned off, but reversed, so that the permanent magnets 40 and the electromagnets 30 attract. This odor trap or the type of operation of the odor trap is also called positively controlled odor trap.
