Drain filters, in particular for washing machines

The innovation concerns a drain filter, especially for Washing machines, with removably arranged "in" a housing Sieve insert.

In known drain filters of this type, which are in the outflow Water flow are installed, the foreign bodies settle on the sieve surface. This creates the sieve surface easily clogged and the water can no longer flow through.

The innovation is based on the * task, the sieve insert to be attached in such a way that he cannot become clogged. This is achieved in a simple and cheap way by the fact that the Water in the filter housing is passed through the sieve surface from bottom to top.

In the drawing the subject of the hiring is to one Embodiment illustrated. Show it:

1 shows a view of a washing machine, partially broken away, with a built-in drain filter,

FIG. 2 shows a diagram of a drain filter according to FIG. 1 in larger scale,

3 shows a longitudinal section through the drain filter along the line III - III in Fig. 4 and

4 shows a cross section through the drain filter along the line IV - IV in Fig. 3.

In Fig. 1, a washing machine 1 is shown with a front Loading door 2. On the drain socket 3 of a tub 4, a drain filter 5 is arranged.

As can be seen from FIGS. 2 to 4, the drain filter has 5 an inlet connection 6 and an outlet connection 7. A cover 8 closes the housing of the drain filter 5 in a watertight manner

In the interior of the filter housing, as can be seen particularly in FIG.

bar, a horizontal screen surface 9 is arranged, which is advantageously attached to the cover 8.

The water flowing in through the inlet connection 6 is through a partition wall 10 at the direct flow to the drain port 7 hindered The water must, in order to get to the drainage connection, flow through the EJiebfläche 9 from bottom to top. The foreign bodies carried along by the lye are retained on the sieve surface 9 and settle in the underlying surface Space of the filter housing from »Ferrous components in the lye are removed from the bottom 11 of the housing inserted magnet 12 held.

On the screen surface 9 and the partition wall 10 is a downward angled Strips 13 attached, which extends to the bottom of the housing and serves as a scratch when removing the sieve insert. The foreign bodies deposited on the floor of the sieve space are scraped out.

An air gap 14 is provided between the partition wall 10 and the upper wall of the housing, so that the existing in the drain Air can escape into the water inlet when the lye is pumped out.

Claims (4)

399225 * 7/31/65 protection claims 1. Drain filter, especially for washing machines, in one Removable sieve insert arranged in the housing, characterized in that the water in the filter housing (5) is passed from bottom to top through the sieve surface (9). 2. Drain filter according to claim 1, characterized in that the sieve insert (9) has an opposite end at its end opposite the filter opening for removing the insert the bottom (11) des'Filtergehäuses directed surface approach (13), which corresponds to the cross section of the filter housing section under the screen area. 3ο drain filter according to claim 1 or 2, characterized in that that the sieve insert is smaller than the interior space of the filter housing (5) serving to accommodate it. 4. Drain filter according to one of claims 1 to 3 _9, characterized in that magnets (12) are arranged in the wall (1i) of the filter housing located below the screen surface.
