Device for preparing kitchen air:

The innovation concerns a device for processing! Kitchen air with an electric motor arranged in a housing and i a suction opening covered by a grease filter. j

Such kitchen air filters that work according to the circulating air principle _? J which are arranged in the usual way above the hotplate, I are widely known. The air to be treated is sucked in by a fan and freed of odorous substances by means of a filter and after this treatment of the room air is sucked in again ί

With these known kitchen air filters, the air to be treated can indeed contain the fat particles contained in it and the! fragrances that cause unpleasant odors are removed «, ^; however, with these known devices, dehumidification; the air to be treated does not take place. ;

The innovation is now the object of a device for treating ι kitchen air to create, in addition to! has a cleaning effect on the air and has a dehumidifying effect. j

According to the innovation, this object is achieved in that the electric motor is connected to an approximately frustoconical drum rotor, the lower shell end of which has openings, and the inner area of the drum rotor adjacent to the shell surface is filled with filter material, which is covered on its underside by an external ring disk., When the sand is pulled in the opposite direction * In this way , the steam to be treated is sucked in by means of the rotating drum and the water droplets collide by turbulence and centrifugal forces, whereby they grow together into larger drops and can then be excreted.

In an advantageous manner, the filter material made of plastic foam and used to separate water becomes a catalytically active one Substance that has an oxidizing effect on the fragrances that cause unpleasant odors, or that absorbs odorous substances Substance (e.g. activated carbon) added. The catalytically active or absorbent substance distributed over the volume d "ft filter material" or else. In. separate layers be arranged.

A particularly convenient renewal of those that are used up during operation To enable catalytically active or absorbent substance, this can also be done in easily exchangeable drawers Or the like. Be introduced in the flow path of the Air are arranged within the housing.

Further advantageous details of the innovation can be found in The following description, in which an exemplary embodiment is explained with reference to the accompanying drawing. It demonstrate:

1 shows a longitudinal section through the kitchen filter, FIG. 2 shows the arrangement of the filter material and 3 shows a longitudinal section through a further advantageous embodiment.

In Fig. 1, 1 designates a housing, which is preferably ' has slots 2. 3 on its top, while its bottom! side a continuous oven covered with a grease filter 4 f ~; showing. Inside the housing 1 there is an electric motor 5 'which is fastened approximately in the middle of the top is. The drive shaft of the electric motor 5, which protrudes into the interior of the housing 1, has an approximately frustoconical design The drum rotor 6 is firmly connected, the lower lateral surface end of which has openings 7. The i The interior of the drum rotor 6 is filled with a filter material 8, for example plastic foam.

An annular disk 9 is attached to the underside of the drum rotor 6, the edge of which is flanged in the opposite direction j is. The edge of the ring disk 9 according to j bent over at the top and provided with bores 10, while the inner j edge of the annular disk 9 points away from the drum rotor 6 under BiI- j tion of a circular opening 11 is bent downwards. Opposite this opening 11 is a likewise circular inlet 12, which is located in the middle of an above the { Grease filter 4 arranged intermediate floor 13 is located. Next j is located inside the housing 1 a preferably! rectangular cross-section having water collecting ring 14, the inside of which is arranged opposite one dan breakthroughs 7 continuous water collection opening 15, while in! the outer side of the water collecting ring 14 leads out of the housing 1 drain pipe 16 opens.

As FIG. 1 shows, the capillary filter, which is preferably made of plastic foam 8, can additionally be mixed with a catalytically active or absorbent substance 17, which over the entire volume ^! of the plastic foam 8 is arranged distributed. I.

However, it is also possible that the Kantelxfläche To fill the inner area of the drum rotor 6 with filter material according to FIG active and absorbent substance alternately arranged in separate vertically extending layers 18 and 19, respectively are.

In order to be able to easily renew the j needing catalytically active or absorbent substance 20 j, this can also be done in drawers 21 or similar! easily interchangeable containers be introduced, which, j according to FIG. 3, above the drum rotor 6 in the region of the j Slots 2, 3 are arranged in the housing i. ;

During operation, the electric motor 5 drives the drum rotor 6 at about 1400 to 2000 rpm, which sucks in the air to be treated through the grease filter 4, the inlet 12 and the opening i1, and pushes it into its areas filled with filter material. As a result of the centrifugal forces acting on the prepared air and the resulting pressure increases, the water particles are separated from the air and conveyed through the bores 10 into the water intake opening 15 of the water intake f ^ rvgringes-14, from which they are conveyed through the drainage pipe 16 outward ; be derived. The conditioned and dehumidified air passes through the openings 7 of the drum rotor 6 and the annular opening between the dumbbell of the drum rotor 6 and the bent outer edge of the annular disk 9 via the slots 2; 3 back into the room.
