The present invention provides an improvement to an air conditioning and extractor hood DE 197 25 935.9 is characterized by a combination of the following features:

1. a) The device has a substantially plate-shaped hood body with a base arranged above it for the connection to the ceiling or wall and a cover arranged underneath, attached to the hood body,
2. b) the lid is formed in a trough shape and has a transparent, downwardly directed window and a filter chamber,
3. c) base, hood body and cover represent a unit formed symmetrically to the central axis and have matching square, rectangular or circular shape,
4. d) the pedestal accommodates a functional box in which are stored the technical devices required for the operation of the device, such as motor, fan, filter, control device and the like, and represents an exchange unit,
5. e) provided between the underside hood body and cover all around air intake for air guidance.

Such a device can be positioned within the scope of the spatial conditions on the wall or at any point of the wall ceiling, since in the case of a circulating hood, ie without connection to the outside, the attachment of the base can be made at any point of the ceiling. On the other hand, the device can be used as a wall hood, if appropriate provisions in the form of a wall-mounted support is provided on the hood is pushed or put on. Optionally, the device can be attached to a false ceiling, such as a suspended ceiling so that the top of the hood body rests directly on the false ceiling and the base between false ceiling and ceiling is arranged so that of the entire device only the lower part of the hood body with the lid and the light window is visible, so that the entire device seen from the viewer as a ceiling light is formed. In the case of such a false ceiling, the air inlet and outlet in the form of a ventilation pipe, in particular a flat channel pipe above the false ceiling and thus invisible be installed in a simple manner.

The lid of the device is hinged to the underside of the plate-shaped hood body so that it can be folded down to open and thus the arranged in the hood body filter and additionally inserted in the lid collecting fleece removed, cleaned or replaced and can be used again. The window in the lid is arranged centrally. The shape of the window or of the window frame, which forms the underside of the lid, is adapted according to the outline shape of the hood body and the base, that is square, rectangular, round or the like. In addition to the downward radiating light behind the light window is on the Top of the hood body provided an indirect lighting, which is independent of the lamp behind the light window switchable.

Hood body and cover are made according to a preferred embodiment of the invention made of stainless steel, but both can optionally also completely or partially made of stainless steel and partly made of glass, the hood body can be a flat or curved glass plate. in the case of execution of the stainless steel hood, the hood body is formed on one side with a flat surface and on the opposite side with conically inwardly facing sections, so that the trough-shaped lid appears inserted into the conical boundaries towards the center and thus the visual impression the lid even more corresponds to a specially designed lampshade. Of the Function box, which receives as a change unit, the technical equipment of the device according to the invention includes the blower, the drive motor, the control of lighting, the operation of the fan and the stainless steel grease filter and the activated carbon filter, optionally pollen filter and the like. The control of these technical facilities is done either manually via push buttons or push buttons on the hood body, or via a remote control. The function box is in the base of the device used so that it is both with the base and with the hood body engaged and in a simple manner with both connectable. This ensures that the technical performance of a hood can be changed by differently designed function boxes, so that thus a particularly efficient production of the hood is possible, and thus a simple replacement in the event of a technical defect is guaranteed.

The base, which is connected to the ceiling, and carries the entire hood, for example, designed as a telescopic base height adjustable, so that the hood can be adapted as a single hood to different room heights. This base has on at least one side surface exit points for the circulating air, on another side surface a connection possibility for an exhaust duct, e.g. a flat channel, for operation as an exhaust hood, the exhaust air duct is led with or without supply air through a wall opening to the outside. Furthermore, the base or the function box accommodates a control or changing device for switching from summer to winter operation and for switching from supply air to exhaust air operation.

a sectional view of the device according to the invention with representation of the function.

The hood body 1 in square, rectangular or circular shape has a correspondingly shaped base 2 and a similarly shaped trough-shaped cover 3. The lid 3 is to open downwards, preferably to fold. In the lid 3, a filtering space 5 is provided. The base 2 and the hood body 1 collectively a function box 6. The lid 3 has oblique side walls or an oblique peripheral wall in the case of the circular formation and in the lid 3, a window 9 is provided, which consists of glass and light from a lamp arranged in the lid, e.g. an annular lamp 14 radiates down.

The FIGS. 4 and 5 are a schematic view of the hood with the lid closed in Fig. 4 and opened lid in Fig. 5 , Another embodiment of a corresponding hood is in the FIGS. 6 and 7 shown. In this case, the base openings 15 for the delivery of the suctioned from the hood air flow, so that the hood is switched to recirculation mode. Fig. 2 shows a further variant in which the hood device is operated in conjunction with a false ceiling, the hood body is mounted on the false ceiling 10, while the function box and the base are arranged above the false ceiling, so that of the hood only the hood body with lid visible is and this visible part gives the impression of a ceiling light.

The air flow in the hood according to the invention is in Fig. 8 presented in conjunction with some details. The base 2 is attached to the ceiling 4 and has distributed over its circumference air duct openings 16, through which the aspirated from the hood air exits the device. The air outlet openings are assigned filter 13 in the form of pollen filters. Furthermore, ionizers can be provided for air freshening and cleaning of fine particles in these areas, as well as ozone-free UV lamps for sterilizing the air flowing through them. Within the base 2 of the function box 6 is arranged, which receives the blower motor 11, the active carbon filter and the stainless steel grease filter 12, the control device 17 and further required for the function of the suction elements. With the control device 17, the speed of the fan motor 11 and the lighting, in different stages - either manually or by remote controlled, carried out, the circuit of exhaust and from summer to winter operation and the connection of supply air is controlled, these functions also by Push button or key switch 18 can be made by hand on the hood body. The indirect lighting on the top of the hood is shown with 19, the connector with 20 on the base 2 and on the function box 6. With 21 an exhaust air or recirculating air channel is indicated, which is preferably formed as a flat channel.
