Description

The invention relates to an air purification device for a residence area immediately in front of a beverage container return vending machine with a return opening for beverage containers and a transport path continued behind for such beverage containers by a transport channel of the return vending machine.

Automatic reverse vending machines are known in many embodiments, for example those with hygienic surfaces, DE 20 2007 000 889 U1 To prevent residues in the beverage containers that inevitably pollute a return machine in the long run and cause that in the return device can form malady or even harmful odors, which can then escape in the worst case from the return opening out in the return area.

A disadvantage of the known reverse vending machine is in particular that a coating with silver particles is not enough to safely protect the room air in a return room from foul smelling or even toxic odors, which may arise, for example, by fixed within the return vending mushroom or bacterial cultures, as well as thus it can be prevented that at a slight pressure difference or draft between a collection space behind the return vending machine and the return room foul-smelling air is transported through the return device back into the return room.

The object of the invention is therefore to provide an air pollution control device for a lounge area immediately before a beverage container return machines available that can safely keep bad and possibly harmful odors from a return room for empty beverage containers.

The solution to this problem arises together with the features of the preamble of the first claim in an inventive manner in conjunction with its technical characteristics of its characterizing part. Characterized in that the air pollution control device consists of an air supply device with an air nozzle, which is directed in the transport path of the returned beverage containers, located in the return machine ambient air through the return opening and the transport channel through, in the transport direction of the beverage container, such a large air flow impressed that excluded may be that a directed back into a return room air flow can be completely prevented. The injected air stream entrains in front of the return opening located immobile ambient air with it, even small amounts of injected air sufficient to produce a permanent strong air flow through a return machine through.

Advantageous embodiments of the subject matter of the invention emerge from and in conjunction with the following subclaims.

According to a particularly preferred embodiment of the invention, the air nozzle is designed as a ring, beam or U-injector or alternatively or additionally consists of several arranged in one or more planes of individual nozzles, so that the invention, for example, randomly before or in round transport channels or can be used before or in angular transport channels, such as for crates, with the air nozzles can be adapted to the different automatic return machines and environmental conditions, so that always the optimal air nozzle or the most advantageous air nozzles can be used.

According to a preferred embodiment of the invention, a plurality of air nozzles distributed over the transport path are arranged one behind the other, not only before the return opening, but also in the transport channel and / or behind the transport channel, so that it can be ensured that maintain the desired air flow safely even with a long transport channel can be, in particular, even if the transport channels of the beverage containers within a return car not optimally round, but are highly rugged, because in addition, the drive devices and detection devices for the different beverage containers are provided.

In a particularly advantageous embodiment of the invention, the air nozzles are designed as pressure nozzles, especially in the area of the return opening, which can certainly convey a very large air mass through the transport channel, for example, by a Ringinjektor with relatively low influx of injected air. Of course, such air nozzles can also be accommodated within the transport channel or at its end, where it may also be useful to form the air nozzles as suction nozzles in order to be able to safely pull the air stream out of the transport channel. If desired or required for operational safety, air nozzles designed as pressure nozzles and air nozzles designed as suction nozzles can also be usefully combined with one another.

According to a further advantageous embodiment of the invention, the air purification device may have an adding device by means of which the injected air stream a germicidal, odor-neutralizing, fragrant or other additives can be added so that all forms of bacteria, viruses, fungi or other pathogens can be safely killed, thereby ensuring that an optimum working environment is maintained even in the collecting space behind the return vending machine.

The air pollution control device is preferably associated with one or more air supply devices which are located in the area of the return station or directly to it and generate an overpressure or a negative pressure as needed, and in the case of overpressure generation, preferably suck the air outside the return area, so that the air purification device always clean fresh air is supplied.

The air purification device can be equipped according to a particularly preferred embodiment as a separate header or retrofit device for a return machine with its own power supply and thereby completely independent of the automatic return, or even be arranged without contact in front of this, an adverse or allegedly undesirable impairment of a return machine effectively rule out.

However, in another preferred embodiment, the air nozzles can also be integrated on and / or in the automatic return device, wherein the air nozzles are optionally magnetically, mechanically, clamped, materially and / or frictionally fastened, glued or integrally with the front side of a return machine before or in the transport path can be formed with the return opening, which allows the possibility of retrofitting existing automatic return machines or the redesign of improved with the inventive air purification device return machines.

Preferably, the air pollution control device is equipped with a controller and a sensor that detects the actual air flow in the transport direction, via the controller, an air flow adjustment of the air injected through the air nozzles is possible, so that, for example, in a strong difference in air pressure between a plenum and a return chamber a possible pressure equalization which would convey air from the plenum into the return room can be safely counteracted by increased performance of the air supply device.
