Definitions
- the invention relates to a shut-off device for a ventilation opening in a building wall, with a shut-off element which closes the ventilation opening in a closed position and releases in an open position and with a drive for the shut-off element.
- Such a shut-off device or such a ventilation opening in a building wall are also referred to as a wall box.
- E in the wall box establishes a connection between the inside and outside space via the ventilation opening and through this connection eg exhaust air is pumped out of a room into the open air and / or supplied with fresh air from outside. They are used for example in the range of hoods in kitchens, so that the exhaust air from the kitchens through the wall box is led to the outside.
- DE 20 2005 010 912 U1 describes a wall box as an insert in a building wall with a ventilation opening for supply air and / or exhaust air, wherein the ventilation opening can be closed by means of a movable from a closed position to an open position closure element.
- the closure element has a lid on which an insulating body is fastened on the rear side. This consisting of the lid and insulating closure element is moved out by means of an electric motor drive in the axial direction of the wall mounted in the fan tube or retracted into this.
- the wall box or its closure only opens automatically when the extractor hood is switched on. In this way, the heat should be kept in the house when the hood is not running, so that - compared
- the known device can be reduced with simple exterior wallboxes with an external grate - heat losses.
- the known device is still subject to disadvantages.
- the device must be adapted to the inserted or inserted into the opening of the building wall pipe. Since the entire drive unit is mounted centrally in the tube and the plug is positioned in the open state in front of the opening, a significant portion of the tube cross-section is blocked. This causes high air resistance, which reduce the suction efficiency of the hood and produce disturbing noises. Incidentally, the thermal insulation can be improved.
- the invention is the technical problem of providing a shut-off device for a ventilation opening in a building wall, which is universally applicable and can also be retrofitted and also ensures improved thermal insulation.
- the invention teaches in a generic shut-off device for a Zu Kunststoff- and / or exhaust ventilation opening in a building wall, that the shut-off device has an externally mounted on the building wall housing having a ventilation aperture associated passage opening and that the shut-off as swivel formed on the housing-mounted shut-off valve.
- the butterfly valve is preferably in the course of opening away from the building exterior side pivoted outward.

- the housing of the shut-off device is externally placed on the building wall.
- the invention also includes embodiments in which the housing is integrated in an outer insulation of a building wall or partially integrated. It will follow I also include sub-plaster variants in which a part of the housing is embedded in the wall and preferably in a recess within the insulation. In these embodiments, an adaptation to the pipe diameter of the wall box or to the diameter of the integrated in the ventilation opening pipe is not required and retrofitting is also possible.
- the shut-off device according to the invention is characterized by an improved thermal insulation, without the suction efficiency of the fume hood being impaired.
- For the shut-off is now designed as a butterfly valve, which is pivotally mounted on the housing.
- the housing itself has a (central) through opening, which is associated with the ventilation opening and approximately in alignment with this, without the ventilation opening or the ventilation tube must match exactly in its dimension with the passage opening of the housing.
- the pivotable articulation of the shut-off valve now makes it possible for the shut-off flap to completely clear the through-opening of the housing and thus also the ventilation opening in the building wall in the open position, without disturbing components being positioned in or in front of the opening.
- the drive for the shut-off valve for example an electromotive drive
- the drive is no longer disposed within the flow cross-section, eg within the ventilation opening, but that the drive is arranged inside the housing of the shut-off device, preferably in one between one Front wall and a rear wall formed interior of the housing, but au ßerhal b of the flow path, is arranged.
- the drive is therefore in the outside
- the passage opening of the housing is thereby e.g. from an inner wall disposed between the front wall and the rear wall of the housing, e.g. formed in the form of a pipe section or pipe socket, which separates the interior of the housing in which the drive is arranged from the passage opening.
- the flap pivots so far that the passage opening is completely released. This means that then the entire cross section of the passage opening is also released in a frontal view of the opening without occlusion.
- the shut-off device according to the invention is also distinguished by improved thermal insulation, so that heat losses are reduced via the ventilation opening or via a wall box. This is achieved, first of all, by the fact that the pivotable shut-off flap with its inner side in the sliding lug against the housing, eg. B. The outer wall of the housing rests. Since the dimensions (width and diameter) of the butterfly valve are greater than the dimensions of the passage opening (width or diameter), a perfect sealing surface is created, so that heat losses are avoided. This can be further improved by the butterfly valve is provided at least on the back with a seal which abuts in the Schl integnagnagnagnagnagnat against a sealing surface of the housing, for example, the outside of the housing. It can be a
