Abstract

Use of a drainage gutter (101) as a floor drain in conjunction with wet rooms in production areas of slaughterhouses or the like, wherein the drainage gutter (101) is adapted to pass waste water to a drain, the drainage gutter (101), when in use, in its bottom part with a bottom channel (107), the drainage channel having a shell shape (103) with curved side walls having a first radius of curvature, and wherein the side walls of the bottom channel are curved and have a second radius of curvature smaller than the first radius of curvature ,

Description

Scope of the invention

The present invention relates to a drainage channel designed to pass waste water to a drainage pipe, wherein the drainage channel, when in use, is designed in its lower part with a bottom channel, and wherein the drainage channel contains a shell shape, the curved side walls having a first radius of curvature, and wherein the side walls of the bottom channel are curved and have a second radius of curvature, which is smaller than the first radius of curvature having.

Background of the invention

In connection with floor drains, z. B. in connection with wet rooms in production areas of slaughterhouses or the like, elongated drainage channels may be provided with a slope in the bottom, whereby excess water is passed through the channels to a drainage pipe.

With small amounts of dirty water, the water can not be channeled through the channels, being in the surface tension of the water at the bottom of the channels until it is flushed out together with a larger amount of dirty water. These small amounts of dirty water, z. Water droplets, such as water droplets, may be left on the ground for long periods of time, forming limescale in the channel as they evaporate, or forming bacteria if the water rots.

WO 2010/047720 A1 discloses a drainage channel. It describes flat side walls that meet at sharp corners. Dirty water can accumulate at these corners, remain for longer periods of time and give rise to the problems mentioned above. Even if the bottom channel has a smaller cross section than the upper main part of the drainage channel, it has a flat bottom. Small amounts of dirty water, z. As water droplets, may also be for longer periods on this flat ground and thus also give rise to the above-mentioned problems.

In addition, drainage channels of the type mentioned in the introduction are in CN 201381548 disclosed. Therein is described an oval drainage channel in which an upper part, when in use, has a radius of curvature which is greater than the radius of curvature for the lower part of the channel. In this drainage channel, the water can be kept at the bottom of the channel at a certain depth to ensure that contaminants can drain rather than being deposited on the ground.

This document does not describe specific parameters to be used to ensure that small amounts of dirty water, e.g. B. water droplets, not resting on the bottom of the gutter.

Object of the invention

It is the object of the invention to solve the above-mentioned problems and to provide a drainage channel, by which it can be avoided that water stands still on its bottom.

Description of the invention

This is achieved according to the present invention by a drainage channel of the type mentioned in the introduction, which is characterized in that the second radius of curvature 1 / 4 of the first radius of curvature and that the height of the bottom channel is less than 1/5 of the total gutter height of the drainage channel.

As a result, a small channel is formed at the bottom of the drainage channel, where dirty water can be collected regardless of the dimensions of the remaining channel. The fact that a small bottom channel is formed by means of the curved side walls, the number of sharp corners can be avoided / minimized. This is a particular advantage because sharp corners are more susceptible to breakage when the drainage channel is formed by bending sheet metal. In addition, such sharp corners may slow water droplets on their way to the bottom channel.

The bottom channel is smaller than the drainage channel and thus less dirty water is required to direct the dirty water to a drainage pipe. The second radius of curvature is 1/4 of the first radius of curvature. This has proven to be an advantageous dimensioning to achieve an optimal drainage of wastewater to a drainage pipe. Now, even small amounts of dirty water can be routed to a drainage pipe, preventing water from standing in the channels. In addition, the curved shape allows to eliminate sharp edges that can contribute to the accumulation of water at the bottom of the drainage channel that is not routed away. In addition, the bottom channel has no flat bottom, which further contributes to the drainage channel is effectively emptied of dirty water.

The height of the floor channel is less than 1/5 of the total gutter height of the drainage channel. This has proven to be an advantageous dimensioning to achieve optimal drainage of waste water to a drainage pipe.

The drainage channel is particularly suitable for use in wet rooms in production areas of slaughterhouses.

In one embodiment, the drainage channel is made of bent sheet steel. This is a simple way of manufacturing and steel also has good hygiene properties with respect to the subsequent cleaning of the channels.

The invention will be explained in more detail below with reference to the attached drawing, in which:

• 1A-D show a drainage channel in accordance with the invention, viewed from different angles.

Detailed description of embodiments of the invention

The 1A-D represent a first embodiment of a drainage channel 101 with a floor duct 107 , seen from different angles, where 1A is a cross section, 1B a view diagonally from above, 1C a side view is and 1D is a view from above.

The drainage channel 101 is designed to pass dirty water to a drainage pipe, giving it a curved shell shape 103 with sidewalls. The drainage channel is at its bottom with a bottom channel 107 designed.

The floor duct 107 forms in comparison to the drainage channel 101 a smaller channel, which allows small amounts of dirty water to be collected in it, and with respect to the relatively small or narrow floor channel 107 form a relatively large amount of dirty water.

In order to achieve a bottom channel that can collect and guide even relatively small amounts of dirty water, the curved shell shape of the drainage channel has side walls with a first slope 105 and have the side walls of the floor channel a second inclination 109 that are steeper than the first slope 105 is on. These slopes can be adjusted to the amount of dirty water depending on the production area in which the drainage pipe is placed.

The bottom channel and the drainage channel have curved side walls with a through 105 designated first radius of curvature and the bottom channel with side walls has a through 109 designated second radius of curvature, which is smaller than the first radius of curvature.

The first radius of curvature may be about 60 mm and the second radius may be 15 mm, which is about 1/4 of the first radius of curvature.

From the figure it can be seen that the height 113 the floor duct is much smaller than the height 111 the entire drainage channel is.

The drainage channel shown in the figure is made of a bent sheet metal, preferably of steel.

The invention is not limited to the embodiments shown in the figures and described above. Within the scope of this invention and the following claims, other embodiments with other forms of drainage channel are conceivable.
