Indoor air cleaning device

The invention relates to portable or stationary room air cleaning devices for cleaning breathing air, consisting of round or square housing with built-in fans and optionally Catalysts, humidifiers, evaporation vessels, electrostatic precipitators, activated carbon filters, odor neutralizers, aerosol atomizers arranged therein or UV lamps and air filter plates for odor adsorption or dust separation.

For reasons of hygiene, it is often necessary in rooms that are contaminated with dust, smoke, smell or germs, unless air-conditioning systems are present, the breathing air from the foreign components contained therein to be cleaned continuously.

These include rooms in hospitals, offices, schools, Restaurants, hotels, residential buildings, canteens, factories, printing works, cold stores, mortuaries, laboratories, crane and vehicle cabins.

In the known room air cleaning devices, the individual air conditioning units are used in a wide variety of ways Arrangements, connected one behind the other or next to one another, built-in. Since these devices are usually portable, the dimensions must be small and the weights as low as possible. As a result, the

The usable space available for cleaning in the devices is limited. However, if the design is unsuitable, small devices usually also emit correspondingly low power. According to the state of the art these devices must be easy to clean and maintain and should have as little equipment as possible and low production costs have a high efficiency.

The state of the art has a number of examples:

DGM 7511783 - OS 2400688 - DGM 7505927 - DGM 7513036 - DGM 7400425 PS ϊ 679 553 - OS 2 351 335 - OS 2240650 - DGM 7337363 - DGM 7334517 OS 2 226 907 - DGM 7333809 - DGM 7304079 - OS 2234228 - OS 2243071 DGM 7205566 - OS 2302243.

The disadvantages of these listed systems are simply: that the available rooms or specific areas of this Devices with a round or square design for cleaning the breathing air have not all been fully exploited economically. These Unused areas take up unnecessary space and in many cases stand in addition to the expense of cladding panels Low pressure and low noise aerodynamic air flow supply and air discharge in the cheapest way only in the way and are one good seldom useful for looking forms of use.

Apart from the fact that it is not always suitable as a cheaper mass-produced device Mass-produced items, most of the devices, especially the angular housings, are nested and constructed with many air deflections, which results in production and assembly difficulties. In addition, there are decorative structures and lamination caps that add to the actual intended use are not necessarily related. All open-

result bar these difficulties but by necessarily be incorporated bulky air delivery and air cleaning units, or their interaction or series connection to a still meaningful, corresponding to the amount of equipment to limit air handling unit to a ¹ smallest possible space.

The majority of known devices for cleaning the room air in of this type are not operational in every possible position of use. This means that special installation or assembly regulations must be observed in order to ensure proper functioning can. These circumstances represent disadvantages to which the manufacturers of such devices have so far not given sufficient consideration. That the same applies to the maintenance, cleaning and recommissioning of such devices. Untrained staff is often unable to overlooked the interval at which a dirty room air purification device brings more harm than good (e.g. in hospitals).

The object of the invention is to avoid the disadvantages listed a simple one for series mass production consisting of a few main parts and individual parts that can be quickly dismantled and show cheap room air cleaning device, which despite a relatively large air passage through a relatively requires little space and is characterized by its low weight.

and from a labyrinth or perforated plate basket 10 for air distribution reasons is surrounded on all sides. The funnel body 8 with the flange 4 designed as a U-profile is on the outwardly directed Angling of the inner perforated sheet metal jacket 2 can be fastened with the screws 6a and at the same time serves as a support for a suspended matter air filter element in disc shape 7, whereby this is effective with its entire specific filter surface. In the funnel 8 of the Device, air treatment devices are used, e.g. catalytic converters, Ozone generator or an aerosol generator 8b.

Figure 2 shows how the flange la with the screw connection 6 and of the disc filter 7 and the hat-shaped labyrinth or perforated plate of the cap 5 in plan view.

Figure 3 as section A-A through the device according to Figure 1 shows the two cylindrical perforated sheet metal jackets 2 and 2a, between which is a zig-zag shaped perforated plate 18b, for example alternately at the tips with the two perforated sheets 2 and 2a is joined together. This constructive measure serves to maintain the circular spacing of the cavities but also to provide mutual spacing Separation 18 of the filled bulk material 3 for the purpose of using the device in any position of use. This shows that granular contact media or the bulk material always have an even layer thickness at all points and reduce sagging the bulk layers to a minimum.

In the middle of the cylinder housing 1 is the horizontal one Fan 11 with the indicated radial impeller and the Auger housing 19 within a perforated sheet metal air distributor basket arranged.

FIG. 4 shows the room air cleaning device dismantled in the axial direction in its 5 main parts. Here is first the overlying angled hat-shaped hood or cap 4 with the Labyrinth or perforated metal sheets 5, which can be connected to the flange 2b of the cylinder housing 1. The part 7 is a zigzag Particulate air filter element unit in disc design, which covered by the hat-shaped hood or cap 4 and 5 and serves as protection against accidental contact and as a pressing or clamping part.

The funnel part 8 in Figure 4 with the U-shaped upper Flange 8d has a contraction on the underside with a round flange 17 on which a labyrinth or closed at the bottom Perforated sheet metal cylinder 10 is attached, which inside the motor 9 and carries the fan 11.

FIG. 12 shows a room air cleaning device standing upright on the floor 26 dar with the handles 28 and the round U-profile apron located on the floor. The air is sucked in here through the filter 31 from above and leaves the cylindrical body on all sides through the perforated plate and from the eruptions of the lower professional apron.

Figure 14 is an upright mobile room air cleaning device 27 with the handles 28 and the rollers 29 and with the lower air outlet 32a.

Figure 15 makes it clear that by assembling the apron attachment 32 on the suspended matter or dust filter element side and thus on the labyrinth or perforated sheet metal cap 4 and then through Turning the device 30 and the handles 28 around the air intake side of the cylinder housing from the usual position in the opposite way comes to rest on the bottom. This inevitably results in a reversal of the intake air direction 32 from the ground.

The mode of operation of the room air purifier according to the invention is best to be explained with reference to FIG. The contaminated atmospheric breathing air first flows through the perforated sheet metal cap and through the particulate air filter element inserted underneath and is first cleaned of dust there. Then the from

-17-709848 / 0129

Dust, smoke and germs cleaned air sucked through the funnel by the fan is evenly distributed from the perforated plate basket out through the hollow cylinder walls and arranged all around through the bottom cavity, which is filled with a granular bulk material for adsorption purposes. This type of air flow is therefore influenced by the fact that the air to be cleaned is first cleaned by a suspended matter air filter element and then subsequently an odor-absorbing filter layer passes.

In contrast, in FIG. 8, the air direction is reversed shown for Figure 1. Here, a fan first sucks the air polluted by odors through the bulk material or Absorbent layers of the cylindrical body and the filled Through the bottom and pushes it through the funnel through the top Attached suspended matter disc filter element as the last stage outward.

Depending on the intended use and the place of use, it will have to be decided on a case-by-case basis in which form the device is most appropriate is to be used. If the air is polluted by odors and possibly not infected by dust, but only by germs, we recommend an air flow direction according to FIG. 8.

But if the air is polluted by dust and germs, and moreover When contaminated with odorous substances, the use of the device is recommended according to Figure 1, first of all the air filter for suspended matter and then the absorber layer is flowed through. The respectively

perforated U-profile apron attached at the bottom in both constructions in FIG. 1 and according to FIG. 6, for example, the cleaned air can escape to the outside. On the other hand, the Profi! Apron the outside air on the cylinder housing in FIG sucked inward through the perforated recesses.

The preferred use of this design is likely to be found in hospitals. The advantages of this room air cleaning device construction are characterized in sequence by the following features:

a) Due to the compact design and the universal usability as an air circulating room air cleaner in the one another independent standing or lying position of use without loss of efficiency compared to comparable devices as well as the stationary or mobile equipping of the invention Device.

b) A major advantage is the possibility of reversing at any time the air flow direction through the device depending on the intended use through a special arrangement of the fans. When using capillary fans, only the direction of rotation is required be changed.

c) Constructively, the advantages of easy to assemble and mass-produced individual parts are still offered. Maintenance can also be carried out by laypeople. This also includes the primitive loading and emptying of the

clock means from the cylinder housing.

d) The separation and the resulting mutual overlap of the absorber layer in the cylinder body and in the The cylinder base is particularly advantageous because in principle it also means that the position of use of the device is independent will. This advantage does not exist on devices of a similar type.

e) The cylinder design shown allows it to be accommodated a flow-favorable) arranged funnel body with it mounted fans in various designs with soundproofing, with the surrounding absorption layer also part of the airborne noise and the structure-borne noise of the Reduced fan absorption.

f) In all exemplary embodiments on the device according to the invention

Care has been taken to ensure that the suction or discharge fans are connected to the arrangement of a air-distributing device always for an even admission the suspended matter filter elements and the absorber layers care for.

g) Finally, as the last and most significant advantage over To emphasize the prior art that all specific areas of the sides of this indoor air cleaning device for the production of air hygiene and air purity without loss of space or without

709848/0129

dead unused space and area fields are used. In this way it is possible that in the smallest of spaces most economical way oversized adsorption layer surfaces and filter surfaces with the air delivery units including their sound absorption as well as the individual air improvement and Air treatment devices can be combined so compactly and sensibly that, despite a large air throughput volume also results in a good-looking and practical form of industry.
