EVAPORATION APPARATUS FOR IMPROVING THE AIR The present invention relates to an evaporation apparatus for improving the air, which is provided with a felt plate for the evaporation fluid and has pipe means on opposite sides of the felt plate which are surrounded by cone-shaped guiding ribs of varying diameter so that said guide ribs have a doublecone contour. The said guide ribs are interconnected by plane-supporting ribs and are, through the latter, also connected to the said pipe means forming an axial pipe member. The apparatus also has a holding ring arranged between the two conical guide rib structures and provided with openings. The evaporation apparatus is intended for improving the air in industrial plants, toilets and the like.

An evaporation apparatus for air improvement equipped with a felt plate for the evaporation fluid has become known.

Such apparatus has an axial pipe structure around which coneshaped guiding ribs of difl'erent diameters are arranged in a double-cone design. In the center of the double-cone design there is provided the felt plate while between the two conical structures there is arranged a holding ring provided with bores.

It is an object of the present invention to provide an evaporation apparatus for air improvement which is provided with a felt plate for the evaporating fluid and has pipe means arranged on opposite sides of the felt plate.

More specifically, it is an object of the present invention to provide an evaporation apparatus as mentioned in the preceding paragraph which can easily be mounted in difierent ways and can easily be opened and closed for exchanging the felt disc.

These and other objects and advantages of the invention will appear more clearly from the following specification in connection with the accompanying drawing, in which:

FIG. 1 diagrammatically illustrates the evaporation apparatus according to the invention as separated from the baseplate, partially in view and partially in section along the line I-l of FIG. 2.

FIG. 2 is a top view of the lower half of the evaporation apparatus according to the invention with mounted-on and locked baseplate in cross section.

The apparatus according to the present invention is characterized primarily in that the holding ring is in a direction transverse to its axial direction and in the central area divided while each section is connected to'the supporting ribs of the cone and is connectable to the other section by a clamping arrangement. Each section carries two parallel pronglike tongues adapted to be inserted into a smooth baseplate and connectable thereto. in this way, the holding ring forms a part of the construction of the evaporation apparatus so that it does not form a loose member which has to be designed in conformity with the other elements in order to fit.

In addition to the baseplate, the apparatus according to the invention comprises only two substantially identical parts, which fact greatly improves the manufacture and stockkeeping of the apparatus and parts thereof. The baseplate oflers the possibility of connecting the evaporation apparatus temporarily or permanently to a wall surface. After the permanent connection of the baseplate, the evaporation apparatus is adapted by means of said prong-shaped tongues easily to be detached from the baseplate or to be connected thereto.

For connection of the apparatus according to the invention to the baseplate, the said tongues have those edges thereof which face each other provided with a recess which combines to an opening adapted to be engaged by an elastic member adapted to interlock with the baseplate.

For purposes of permitting detachment of the evaporation apparatus, according to the invention, from the baseplate, the baseplate is, for releasing said locking member on each side, provided with a recess which permits access from the outside to said locking member.

In order to be able selectively to connect the baseplate temporarily or permanently to a wall, the baseplate is provided with a bore, two suction fasteners and has its back side provided with pressedon, self-sticking tapes. For protecting the self-sticking tapes or bands, the baseplate has its rear side provided with four spacer means adapted to be cut off.

Advantageously, the two sections of the holding rings are provided with a spring and a groove forming the clamping closure means. 7

Referring now to the drawing in detail, the apparatus illustrated therein comprises two cones l and 2 mounted in such a way as together to form a double cone. Said cones extend around an axial pipe 3 and 4 respectively. Each cone comprises conical guiding

ribs

5, 6 respectively, of varying diameter and arranged in the manner of stairs. The upper guiding ribs 5 are flaring upwardly and the guiding ribs 6 are flaring downwardly. The guiding

ribs

5, 6 of each cone are held by a supporting star member 7, 8 comprising six supporting ribs. The guiding

ribs

5 and 6 are injection molded and consist of one single piece of any suitable synthetic material with the supporting star members 7, 8. The supporting ribs of the two members 7, 8 are fixedly connected at their outer edges 7a, 8a with a

portion

9a and 9b of a circular holding ring 9. At those of their edges which face each other, the two sections 90, 9b of the holding ring 9 have one-half thereof provided with a spring 16 and another half provided with a groove 17. These members form a clamping closure arrangement which holds the two

sections

9a, 9b of the holding ring 9 together after they have been assembled. The holding ring 9 is completely provided with openings 10 in order to obtain a lateral air entrance.

In the interior of the apparatus according to the invention there is provided a felt plate 11 which has bores Ila.

The axial pipes 3 and 4 are closed by stoppers I2, 13 respectively. The upper stopper 12 is detachable in order to permit the evaporation liquid to flow through the pipe 3 of the felt plate 11. The lower stopper [3 may be inserted permanently into the pipe 4.

In view of the double-conical design, the air entering the apparatus from below will be directed in the direction toward the felt plate for the evaporation liquid. In view of the evaporation, an airflow in upward direction will be created. This airflow will be passed through the upper conically arranged guiding ribs. Thus the evaporation apparatus is passed through by air from the bottom toward the top.

The circumference of the two

sections

9a and 9b of the holding ring 9 has fixedly arranged thereon two insertable tongues l4 and 15 which, at those edges that face each other, are respectively provided with a recess 14a and 15a, said recesses together forming an opening l8. The tongues 14 and 15 located in one plane are insertable in two pockets 19 of a smooth baseplate 20. These pockets 19 have their inner wall provided with an opening 22 from which an elastic member 23 is formed which is bent at an incline toward the outside. When inserting the said tongues l4, 15 into the pockets 19 of the baseplate 20, the said members 23 are first by the outer edges of said tongues elastically pressed inwardly. After the tongues have been completely inserted into the pockets 19, they will, due to their own elasticity, spring into the openings 18 of the tongues and have their end faces rest before the outer edge of the openings 18. The evaporation apparatus and the baseplate are now permanently connected to each other.

For purposes of detaching the apparatus from the baseplate 20, the outer walls of the pockets 19 are provided with recesses 24 through which the member 23 can be pressed inwardly to such an extent that it leaves the opening 18 and the tongues 14, I5 can be withdrawn from the pockets 19.

The baseplate 20 is smooth and. for purposes of a temporary connection to a wall surface, is provided with suction cups 25 of which the upper one can also be pulled out from its holding opening in the baseplate. The baseplate with the evaporation apparatus is then suspended on a hook by means of the holding opening. For permanent connection, the rear side of the baseplate 20 has two self-sticking tapes or hands 26 pressed thereon which, after withdrawal of a protective foil,

can be pressed against the wall surface. Before this is effected, however, four members 27 have to be arranged on the rear side of the baseplate 20 and previously forming spacer means for protecting the selfsticking bands have to be cut off smooth. Finally, in the center of the baseplate 20 there is provided a screw hole 28 for permanent connection of the baseplate to a wall surface.

It is, of course, to be understood that the present invention is, by no means, limited to the particular construction shown in the drawing but also comprises any modifications within the scope of the appended claims.
