PL LU100967

YY # ANM PATENT Description: Schreinerei Bauer GmbH, 66822 Lebach (Germany) "Device for preventing mold formation on a seating or reclining furniture" _ I The invention relates to a device for preventing mold formation on a sitting or reclining furniture, in particular on one Mattress of a bed, a slatted frame or in a bed box, which comprises a ventilation device which is used to move a gas from a first room, in which the seating or reclining furniture is located, in at least | another room, which is limited by a section of the seating or reclining furniture.

Mold usually forms on poorly ventilated and damp places on seating or reclining furniture. It is known from the prior art that mold formation can be prevented, for example, by spraying the furniture with chemicals which are harmful to humans.

The present invention has for its object to provide a device of the type mentioned, which enables the prevention of mold growth without the use of chemicals.

According to the invention, the object is achieved in that the ventilation device has at least one gas outlet channel through which the gas can flow into the at least one further space.

A gas, in particular fresh air, can advantageously be directed to moist or poorly ventilated points in the further room, for example to improve air exchange or to effect drying and thus prevent mold formation. For example, the room in a closed bed box or under a bed, which is delimited by a slatted frame and the underside of a mattress, is susceptible to mold formation. Especially in summer, when a person using the bed sweats at night, the humidity in a bedroom increases. Moist air builds up under the bed, since this area can often be insufficiently ventilated due to its location shielded by the mattress and a bed frame despite good bedroom ventilation. By means of the device according to the invention, ventilation and, if appropriate, drying can be effected in rooms 1/7 inadequately ventilated rooms, for example under furniture such as beds, sofas or armchairs, and mold formation can advantageously be avoided.

At least one gas inlet channel is expediently provided, through which the gas can flow into the device from the first space and which is arranged perpendicular, parallel or obliquely to the at least one gas outlet channel. The gas inlet channel and the gas outlet channel are fluidly connected to one another. An outflow direction of the gas into the at least one further space can advantageously be determined by arranging the channels relative to one another. This ensures that the gas can be distributed homogeneously in the further room and that the seating or reclining furniture to be protected against mold formation, which can include a mattress or a seat cushion, is adequately flowed for gas exchange, air circulation and / or drying to enable and / or to avoid the formation of a damp area. It is conceivable that a plurality of gas inlet channels, which are arranged parallel or at an angle to one another, are provided. A larger volume flow can advantageously be achieved when flowing into the device from the first room and consequently when flowing out into the further room. In one embodiment of the invention, the at least one gas outlet channel has a slit-shaped gas outlet opening. The gas can escape along the entire slot and can thus be distributed particularly well in the further space and, for example, flow over a large area of an underside of a mattress of a bed. Particularly good ventilation of the further room or particularly good drying of the seating or reclining furniture is advantageously possible. In a further embodiment of the invention, in the at least one gas outlet channel or in the area of an outlet opening of the at least one gas outlet channel, a means for changing an outflow direction of the gas is provided, which preferably comprises adjustable, mutually parallel steering plates. Advantageously, an outflow direction can be changed, in particular manually, in order, for example, to specifically direct outflowing gas to a specific point on the seating or reclining furniture. It is also conceivable that the means for changing an outflow direction comprises a drive, preferably an electric drive, by means of which the steering plates can be moved into a specific position, or which is set up for a periodic pivoting movement of the plates. As a result, the gas can be distributed even better in the further room and particularly good ventilation can be achieved at certain points.

A plurality of gas outlet channels are expediently provided, which are preferably arranged parallel or at an angle to one another and which preferably have lower sections which are provided for the movable, in particular pivotable connection with at least one gas inlet channel.

The gas outlet channels could, for example, be provided as movable, in particular cylindrical, branching elements which are fluidly connected to the at least one gas inlet channel.

A gas distribution in the further room can be adjusted by targeted alignment of the branching elements.

In one embodiment of the invention, a plurality of gas inlet channels are provided, which are arranged coaxially, in parallel, perpendicularly or obliquely with respect to one another, with a means for sucking in the gas from the first space being provided in at least one of the gas inlet channels, preferably a fan wheel.

The suction means can, for example, be electrically | be operated and a control device for setting a speed of a fan wheel can be set up.

A volume flow of the gas drawn in from the first space is advantageously adjustable.

If a large amount of gas is to flow in in a short time, the fan wheel could be operated at a higher speed.

If, for example, quiet operation is required at night, a low speed could be set.

Although it is conceivable for an end section of a gas inlet duct to be arranged in the further space delimited by a section of the seating or reclining furniture or to be flush with an interface of the two rooms, in a further embodiment of the invention the end section protrudes into the first room.

This is particularly advantageous if the two rooms are not separated from one another, for example if air is drawn in from a bedroom and is to be distributed under a piece of seating or reclining furniture.

In addition, it is ensured that predominantly gas is withdrawn from the first room and led into the further room, so that a circulation is created.

In one embodiment of the invention, the ventilation device has a means for setting a temperature of the gas and / or a means for drying the gas.

This means can comprise, for example, a heater and / or a gas drying device, which can in particular be introduced into the gas inlet and / or gas outlet channel.

Drying a moist area in the further room can advantageously be improved.

A time switch unit is expediently provided, which is preferably set up to activate the ventilation device.

The device can advantageously be used independently of time.

For example, ventilation of an underside of a mattress can take place during the day when a bed is not in use.
