Description

Ventilation device {VENTILATION DEVICE}

The invention relates to a ventilation device according to the preamble of claim 1.

BACKGROUND Ventilators for sheets are known in which air is blown through the seat cover by the ventilator.

It is therefore desirable to develop a technical solution which is desirable, improved, or alternative to the manufacturing costs of the ventilation device, the ability to create comfortable indoor air conditioning conditions, and / or energy consumption in particular.

In the background of the prior art mentioned above, a technical concept comprising the features of claim 1 is proposed. Further preferred constructions can be found in further claims and in the description that follows.

From the numerous conceivable possibilities, such as moisture absorbing materials, continuous operation of the ventilation device, replacement of the conductive layer with the ventilation device just below the cover surface, it is surprisingly here only to distinguish air permeability and vapor permeability from the materials used. Even enough, the inventors have found a solution that can improve indoor air conditioning conditions even when the ventilation device is turned off.

The ventilation device according to the invention allows for efficient ventilation during operation of the ventilation device and at the same time ensures that moisture does not accumulate on the surface to be ventilated and / or the skin of the user even when the power supply of the ventilation device is cut off.

In the following the invention is described in detail. As a result, the present invention can be understood. However, the features of the embodiments are for illustration only. Accordingly, individual or multiple features described in the scope of the invention as obvious facts may be omitted, partially altered, or supplemented. Also, features of the various embodiments can be combined with each other as obvious facts. In other words, the important fact is that the concept of the present invention can be converted in nature. If the feature is at least partially met, this implies that the feature is either fully met or essentially completely met. The term "essentially" here denotes in particular that the conversion allows the achievement of the desired use to a degree that can be ascertained. This may in particular mean that the corresponding characteristic is met by at least 50%, 90%, 95% or 99%.

According to the ventilation device according to the present invention, ventilation is efficiently performed while the ventilation device is in operation, and moisture is not accumulated on the surface to be ventilated and / or the skin of the user even when the power supply of the ventilation device is cut off.

In the following, embodiments of the present invention are described in more detail with reference to the drawings.

In this connection, as a measure for diffusion, the value of s _D , which is expressed as the product of the diffusion resistance coefficient μ according to the material and the layer thickness d, is considered. In this case, in particular, if the s _D value ≤ 0.5m in accordance with DIN 4108-3, the layer is considered to be capable of diffusing; if the s _D value ≥ 1500 m, it is considered to be diffusion resistant, and the s _D value is 0.5 m and If it is 1,500m, it is regarded as suppressing diffusion. At least one barrier layer 125 preferably has at least one whose vapor permeability to s _D value is at least 0.5 m, preferably at least 10 m, more preferably at least 1,000 m, or more preferably at least 1,500 m.

Preferably, the barrier layer covers the entirety of the surface of the distribution layer 124 facing away from the user, while further protruding slightly at one or more edges. This prevents air and pressure losses. At least one barrier layer 125 is formed at least in part of a foil, or a layer of plastic, polymer or other material that is poorly permeable, such as, for example, metal foil. The blocking layer 125 is preferably formed as only one layer of homogeneous material.

Barrier layer 125 may include one or more air passage openings 127, for example, to connect a ventilation device.

Cover layer 126 includes one or more air passage openings 127 ′, for example, to allow for connection of ventilation devices. In this regard, the air passage openings 127 ′ may be used as the air inlet 121 leading into the air guide device 122 when the ventilation device connected to it must blow air toward the user. In addition, the air passage openings may also be used as the air outlet 123 when air is sucked in from the user by the ventilation device.

However, this coupling is not provided over the entire edge of the air guide device 122, among which air passages can be introduced into the distribution layer 124 on the side, or to suck out the air again from the distribution layer. Openings 127 are also provided. In addition, a snorkel portion 129 (snorkel) may be disposed in the region where the air passage opening is provided to allow the air guide device 122 to be coupled to a position spaced from the surface to be vented, as shown in FIG. 3. have. This may serve for example to suck cold air from the foot space of the seat.

Preferably, even when the power supply of the ventilation device is cut off, the interior of the air guide device 122 communicates with the air of the surface to be vented or the surrounding environment of the sheet 1110. Thereby, in the air passage openings 127 spaced from the surface to be vented, moisture diffused into the air guide device 122 through the cover layer 126 can be discharged.
