Description

Floor drain 7 0 9 61

Golvbrunn

The invention relates to a floor well having, for example, a cylindrical, conical or the like, a substantially vertical side wall and a substantially horizontal bottom, the outlet wall of which has an outlet for draining water out of the well.

Floor drains used in saunas, bathrooms, and the like are generally cup-shaped, upwardly open containers with an opening in the wall for an outlet pipe or equipped with a short horizontal outlet pipe. The mouth of the well usually has a grate or perforated lid 10 through which water flows into the well and water leaves the well through an opening or drain pipe into the drain. Pipes of several different sizes can be used as drain pipes, in which case for each pipe size the floor drain must be equipped with a connection of this size, such as an outlet pipe. As a result, several different types of floor wells have to be manufactured in storage, as a result of which their storage costs become high. From a manufacturing point of view, such a solution is also bad, because when changing the well type during manufacturing, the tool has to be changed from time to time, which slows down the manufacturing process.

It is an object of the present invention to provide a new type of floor well which does not have the above-mentioned disadvantages. The invention is characterized in that two nested outlet pipes projecting from the wall and directed away from the well are formed in the wall at the outlet opening.

An advantage of the invention over the prior art is that the floor drain according to the invention is suitable for two different pipe sizes. This simplifies the manufacture, as it is possible to manufacture the same type of floor film in larger series. As a result, storage costs 30 are also lower because there is no need to stock several different types of floor wells.

The invention will now be described by way of example with reference to the accompanying drawing.

The basin of the floor well according to the invention is of conventional construction. The wall 3 of the basin can be cylindrical or it can be formed gently conical, tapering downwards, as can be clearly seen in Figure 2. The bottom 4 of the well can be flat as shown in Fig. 2 or it can be formed slightly inclined towards the outlet opening, which facilitates the drainage of water from the well. If the well is made of a plastic, for example by means of a mold, the conical shape of the wall is more advantageous than a cylinder, because the body then detaches more easily from the mold. The upper edge 5 of the wall 3, which is mounted at the level of the floor surface, is formed as a flange. In addition, a recess 6 is formed in the upper edge of the well, in which the cover of the well is mounted.

The novelty of the floor drain compared to the prior art is in the structure of its outlet pipes 1 and 2. According to Figures 1 and 2, two nested outlet pipes 1 and 2 are formed in the floor drain wall 3 20. Preferably, the outlet pipes 1 and 2 are arranged nested concentrically. Of the outlet pipes, only the inner pipe 1 leads into the well. The outer pipe 2 terminates in the wall 3 of the well. Water can then escape from the well only through the inner pipe 1. Such an arrangement allows the installation of a well in connection with two sewer pipes of 25 different sizes. The drain pipes are thus arranged either on the inner pipe 1 or on the outer pipe 2.

Due to the arrangement of the outlet pipes 1 and 2, the bottom 4 of the well could not be formed just below the bottom 3, but the bottom 4 has been raised some distance above the bottom so that the walls 3 continue below the bottom 4 as a kind of "base" 4 should be located at substantially the same height as the lower edge of the opening from which the water is led out of the well. If the base 4 were located just below the walls 3, there would be a space 35 below the lower edge of the riser pipe 1 from which water would not be allowed to flow away. Although Figure 2 shows that the base 4 is located some distance below the lower edge of the pipe 1, in a more preferred embodiment the base 4 is located at or even slightly above the lower edge of the pipe 1 70961. If the base 4 is located above the lower edge of the opening, a suitable recess will naturally be formed in the base 4 at the mouth of the opening to facilitate the drainage of water. The floor drain according to the invention is preferably made of plastic, but other materials can be used.

The double pipe structure according to the invention is also suitable for use in wells other than in connection with floor wells. One particular application is rainwater wells, as rainwater wells of the same size can be used in 10 different sized drainage systems. Sewerage systems of different sizes, on the other hand, naturally use different sizes of sewer pipes, so the double pipe structure of the rainwater well allows the well to be adapted to different pipe collections.

The invention has been described above with reference to an embodiment shown in the figures. However, this is in no way intended to limit the invention to this example only, but many modifications are possible within the scope of the inventive idea defined by the following claims.
