Description

Exhaust air chimney for an exhaust hood

The invention relates to an exhaust chimney for a

Exhaust hood with a fireplace housing and with a

Connecting device for fastening a

Exhaust air collecting device.

An exhaust hood such as an extractor hood usually has at least two housing parts. In an exhaust air collecting device, the exhaust air is detected and supplied to a Kamingehäuse, which forms an exhaust duct and can discharge the exhaust air detected with the exhaust air collecting device.

From practice, different embodiments of cooker hoods are known. A wall hood points

For example, a flat or L-shaped configured Abluftsammeieinrichtung, as well as the

Fireplace housing with a back attached to a wall. In an island hood, a flat, roof-shaped or convexly curved exhaust air collecting device is fastened by means of a suitable connection device to a lower end of a fireplace housing, which in turn usually has a ceiling at its upper end

is fixed.

The connection device can, for example, a circumferential mounting flange, from laterally projecting Tightening tongues or from openings or boreholes are formed, which are responsible for a determination of

Abluft collecting means are suitable to the fireplace housing. The fireplace housing is usually made of a

Wall covering made of stainless steel, which may be configured in one piece or in several parts and has a circular, rectangular or square cross-sectional area.

The for the removal and cleaning of the exhaust air

required exhaust air treatment facilities are

usually in the exhaust air collecting device in which

Fireplace housing and possibly outside the

Kamingehäuses arranged in a subsequent section of the flue. In the exhaust air collecting device is often a filter device, the

For example, has an impact filter or a filter fabric. A fan, with which the exhaust air flow can be generated, is located either in the fireplace housing or in a subsequent section of a chimney or outside a building, provided that

Extractor hood is not operated in recirculation mode and no other section of a flue is present.

The Kamingehäuse and located on the Kamingehäuse connection device must also in terms of

optionally arranged in the fireplace housing

Exhaust air treatment facilities to the respective

Be adapted exhaust air collection device.

It is therefore regarded as an object of the present invention to design an exhaust chimney for an exhaust hood so that the exhaust chimney with the lowest possible Made effort and used for differently designed exhaust hoods or in a simple manner

different uses can be adjusted. This object is achieved in that in the Kamingehäuse several receiving devices for

Receiving exhaust treatment devices are spaced from each other. The exhaust air treatment ^{¬ facilities} can easily from the

Receiving devices are recorded and set in the fireplace housing. Depending on the for the

Exhaust air collecting device used in each exhaust hood can be those required for the exhaust air treatment

Exhaust air treatment devices in the fireplace housing

to be ordered. The fireplace housing can be produced in a simple manner and inexpensively together with the receiving devices uniformly and then depending on the particular exhaust air collecting device used

adapted and individualized.

It is also conceivable that all

Exhaust air treatment devices are received by each associated receiving devices in the Kamingehäuse and therefore completely housed in the Kamingehäuse. In this case, the exhaust air collecting device merely serves to detect the exhaust air to be discharged with the exhaust air hood and to supply it to an inlet opening in the fireplace housing. Since the exhaust air collection device is not

At the same time must also absorb exhaust treatment facilities such as filters or fans, any Abluftsammeieinrichtungen can be combined with such a fireplace housing for an exhaust hood. It is preferably provided that the receiving devices in each case two at opposite wall portions of the

Kamingehäuses arranged profiled rails.

Suitable rails, which may for example have an L-shaped or a C-shaped profile can be easily and inexpensively manufactured or purchased commercially available and fixed without major installation effort in the Kamingehäuse or defined therein. The Kamingehäuse can be a substantially arbitrary

Have cross-sectional area, wherein the attachment of the rails with a rectangular or square cross-sectional area can be particularly simple and inexpensive.

According to an advantageous embodiment of

According to the invention, it is provided that the profile rails form a lateral guide for a slot. A fast and at the same time reliable arrangement and

Fixing the individual exhaust air treatment devices in the fireplace housing can be made possible or supported by the fact that the individual exhaust air treatment devices are each designed as a slot whose

Dimensions of the receiving devices or on the

Kamingehäuse are adjusted. The different ones

Exhaust air treatment facilities such as

Fans or filters can either have standardized dimensions or external shapes or by the arrangement of lateral guide elements to the

Shaping and arrangement of the in the fireplace housing

be adjusted profile rails. The

Profile rails can also be independent of the Design of the fireplace housing with respect to their spacing or their shape uniformly designed or

be standardized.

Due to the modular design, the individual

Exhaust air treatment facilities almost arbitrarily combined with each other and are arranged in an advantageous for the intended treatment of the exhaust air sequence in the Kamingehäuse. An exchange of a

individual exhaust treatment device is easy and quick. Since the individual exhaust treatment ^¬ devices for their use and arrangement can be prepared or prepared in a Kamingehäuse, complete exhaust hoods can be made of individual

quickly assemble prefabricated components.

In order to be able to ensure a particularly high mechanical stability, it is provided that a frame for fixing the receiving devices is arranged in the fireplace housing. The frame may be formed of a plurality of interconnected struts. It is also conceivable for a frame plate arranged on a rear wall to have holes,

Having recesses or other suitable fasteners that allow rapid and reliable fixing of the rails or the individual exhaust treatment facilities on the frame.

A particularly versatile, easy on

Different designs and requirements customizable design can be achieved that the

Receiving devices are detachably fastened to the frame. Depending on the case in each case provided exhaust treatment devices or their respective design or structural design, the respective associated receiving devices can be arranged and fixed to each other at the correct distance from each other. Optionally, the individual exhaust treatment devices together with the

Receiving devices are detached from the frame or fixed to the frame.

An advantageous embodiment of the inventive concept as a result is provided that the Kamingehäuse a

Has removal opening for a slot. In particular, in the case of a filter or another maintenance-requiring exhaust-air treatment device, a removal opening can be arranged and configured in the firing housing in such a way that the associated exhaust-air treatment device can be removed or reused with a handle.

It is also conceivable and with regard to the simplest possible accessibility of the individual exhaust air treatment ^{¬ facilities} expedient that the Kamingehäuse has a pivotally mounted maintenance flap. The

Maintenance flap can be opened laterally, for example, about a vertically arranged pivot axis. With regard to an optically as discreet design of the maintenance flap can be provided that the

Maintenance flap is formed by a side wall of the Kamingehäuses, which can be fully unfolded, so that no joints or fissions are disposed within a side wall of the Kamingehäuses. The maintenance door may also be, for example, horizontally around one at a lower end or at an upper end of the chimney housing arranged pivot axis to be pivotally mounted and, if necessary, be opened up or down to remove the individual exhaust treatment facilities, wait and reuse.

Hereinafter, embodiments will be discussed in more detail, which are shown in the drawing. It shows:
