Extractor device

The innovation concerns an extractor device with Inevitable air routing for installation in an opening in the outer wall.

Known extractor devices of this type only suck air out of a room, e.g. above a hob, and lead them to the outside through an opening in the outer wall. The extracted air is replaced by supply air that enters the room penetrates through various openings and cracks, especially on doors and windows. Such an air duct is not optimal, since the haze is also found outside a usually provided extractor hood of the device, in particular can accumulate under the ceiling of the room and from there insufficient is extracted: In addition, known range hood devices ■ are difficult to adapt to different local conditions, E.g. the room design and the thickness of the outer wall are adaptable and do not have sufficient control options.

The innovation is based on the task of avoiding an extractor device of the type specified above of the disadvantages indicated above so that they allow a regulated supply of possibly heated supply air with ge · ' - Separate control of the exhaust / supply air supply and simple assembly with a simple and operationally reliable overall structure the device allows.

This object is achieved by an extractor device with the features specified in protection claim 1. . Preferred embodiments are in. unsuccessful given.

The extractor device according to the innovation is explained by the following description of an exemplary embodiment

spiels ·, <refer to the attached drawing. Here in demonstrate: ' '

1 shows a schematic longitudinal section of the extractor device in a ready-to-use condition!

FIG. 2 shows a schematic representation of the individual parts of the device in FIG. 1 in an exploded state.

The embodiment shown in Figures 1 and 2 of an extractor device according to the innovation has an exhaust duct 1; which is connected at one end to a not shown, known Dian rod hood. In this, in a manner known per se, metal grease trap filters and lighting devices are provided for the cooking area arranged under the extractor hood. At its other end, the exhaust air intake duct 1 carries a connector 11 which extends up to, in or over a corresponding pipe connector 33 of the exhaust air chamber 31T and interacts with it. The wall box 4, which 'consists of two parts 41 ', 42 which can be telescoped into one another, is inserted into the opening in the outer wall. This means that the wall box can be adjusted for wall thicknesses, tone, for example, 29 to 41 cm. A blower block 3 can be inserted into this wall box, which contains an exhaust air chamber 311 and a supply air chamber 312 in a straight tube 310, which is open on both sides and whose outer cross-section is designed to be suitable for insertion into the wall box 4, which through a whole in a .Longitudinal plane of the tube extending partition wall 30 are formed in this, which are connected to the connecting piece 33. · Exhaust air chamber 311 contains an exhaust air fan 31, while the air intake fan 32 is arranged in the air intake chamber 312. By appropriate design of the partition wall 30, the.

To achieve be staggered with it s' Motor en blower ne to e% compact construction and low air flow.

After the blower block 3 has been inserted into the wall box 4, the blower block is in its position of use an inner cover surrounding the nozzle 11 of the exhaust air intake duct 1 and possibly connected to it. 2 together with the exhaust duct 1 attached to the wall box 4. · On the other side of the wall box 4, its opening is through an outer cover 5 covered which on the inside

carries a baffle 53 which, in the position of use, continues the partition wall and on the outer surface of the outer cover an exhaust air outlet opening 51 separates from a supply air inlet opening 52. These openings are usually provided with saw slots 54 for air routing, which also prevent the ingress of rain • The area of the exhaust air outlet opening or supply air inlet opening corresponds approximately to the amount of exhaust air or supply air to be conveyed.

The inner cover 2 is formed in the area of the air inlet chamber 312 with an air inlet outlet opening 22 which is flat if it has slanted slots for air routing.

In the supply air chamber 312 is between its outlet opening and the supply air fan 32, a heater 6 is arranged, which, controlled by a thermostat, controls the supply air flow entering the room, if necessary, heated.

The mains connection cables and control cables of the motors · the Blowers 30 and 32 and the heater 6 are led to a connection point on the exhaust air suction duct 1, where they are touch-safe End plug connections that are connected to the electronic control components.

If necessary, an extension duct (not shown) is connected to the supply air outlet opening 22 in order to possibly Heated supply air to one or more points in the: -, ceiling area of the interior. The outlets on such a supply air extension duct are optionally also provided with inclined slots for the air flow.

The innovation has the advantage that separate covers for the inner and outer walls make it possible to assemble the wall box and the extractor device in a time-phased manner, depending on the construction progress, so that any assembly tolerances can be absorbed. The ^M building block construction ¹¹ enables simple removal of the housing block 3 without masonry work, even in the event of maintenance and repair.

The extractor hood not only sucks in the usual way. through the. Extractor hood exhaust air and leads it to the outside, but also replaces a definable part of the extracted

In this way, the supply air pulls the vapors down to the exhaust air hood.
