In particularly preferred embodiments of the device for extracting cooking fumes according to the invention, the cooking fume inlet device can 2nd on top of a countertop 10th top-mounted (for example 6 ) or flush (for example 7 ) be installed.

As a rule, is directly or indirectly on the underside of the cover frame 6 a grease filter 9 and a short channel-shaped approach 12th to hold the grease filter 9 intended.

This combination of cover frames 6 , Grease filter 9 and channel-shaped approach 12th can preferably engage tightly and precisely using the hanging technology in the top-mounted or flush-mounted cooking fume inlet device 2nd be attachable.

Between the cover frame 6 and the channel-shaped approach 12th to hold the grease filter 9 can, for example, a circumferential or section fold for positioning and for tightly receiving the lid-shaped closing device 5 be provided (see for example 6 ).

Like, for example 17th shows can below the cooking fume inlet 4th one or more gutters 14 for grease or spilled liquid in the wall there 15 the cooking steam inlet device 2nd or its exhaust air duct 3rd be provided.

As in particular, 4th , 6 , 17th and 18th can be seen in the gutter 14 the wall 15 the cooking steam inlet device 2nd reversible a liquid drip tray 39 can be used and removed from this.

In addition, the wall 15 the cooking steam inlet device 2nd in particularly preferred embodiments of the cooker extractor device according to the invention via the liquid collecting tray 39 at least partially in the form of a drip nose 37 protrude.

The 17th and 18th show that in the gutter 14 the wall 15 reversible liquid drip tray 39 one or more holder-like, the liquid collecting tray 39 protrusions completely or partially 38 to support the grease filter (s) 9 can have.

How in particular 8th shows, the lid-shaped closing device 5 a fold for positioning and centering the lid-shaped closing device in its edge area and on its underside 5 above the cooking fume inlet 4th wear.

The surface 16 to support the lid-shaped closing device 5 provided edge of the cooking fume inlet device 2nd or the cover frame 6 can in this case be aligned completely or in sections horizontally and / or obliquely in the direction of the cooking vapor inlet opening 4th be inclined.

In this case, preference is given to that on this surface 16 overlying flank 17th of the fold of the lid-shaped closing device 5 corresponding to the alignment of the surface 16 the edge of the cooking fume entry device 2nd or the cover frame 6 aligned.

For centering the lid-shaped closing device 5 on the underside of the lid-shaped closing device 5 Providing a fold is particularly advantageous because it creates a dirt fold on or in the cover frame 6 is no longer required for the first time.

In particularly preferred embodiments of the device for extracting cooking fumes according to the invention, the cover frame can 6 the cooking steam inlet device 2nd flush to the top of the worktop 10th in a fold 26 on the top of the countertop 10th and in the edge of the cooker hood at the inlet opening, indirectly or unseated ( 7 and 8th ). indirectly

Like among others 7 , 8th and 9 can show below the bottom of the countertop 10th a clamp 27 outside on the channel-shaped approach 22 the cooking steam inlet device 2nd be provided, which is a vertically adjustable clamping screw 28 for clamping the cooking fume inlet device 2nd on the worktop 10th wearing.

From the 10th and 11 shows that towards the cooking fume inlet 4th facing edge area of the cooker hood 11 the worktop 10th on its top one towards the cooking fume inlet 4th inclined slope 30th can have.

In the edge areas of the lid-shaped closing device 4th can then be formed, for example, a fold, one flank 17th to the slope of the slope 30th is correspondingly adapted and the other flank is oriented vertically.

The one in the direction of the cooking fume inlet 4th facing edge area of the cooker extractor 11 the worktop 10th can then fold on its underside 29 have, in which the cover frame 6 the cooking steam inlet device 2nd or the channel-shaped approach 22 the cooking steam inlet device 2nd is installed in a substructure ( 10th ).

As an alternative to this, the cooking steam inlet device can be used 2nd or the channel-shaped approach 22 the cooking steam inlet device 2nd without fold 29 in substructure mounting directly on the underside of the worktop 10th to be appropriate ( 11 ).

The 12th to 16 show that in one or in both opposite, longitudinal edge areas 18th the cooking steam inlet device 2nd and / or the cover frame 6 and / or the channel-shaped approach 22 below the cover frame 6 vertically or obliquely in the direction of the cooking fume inlet 4th inclined grooves 19th or trough-shaped depressions or recesses to the vertically vertically aligned or in the direction of the cooking vapor inlet opening 4th obliquely inclined reversible insertion of the lid-shaped closing device 5 can be provided.

This insertability of the complete or partial lid-shaped closing device 5 in an oblique orientation is particularly advantageous from the aspect of a target-oriented orientation of the cooker extractor flow only to the respective active hob (see in particular 12th ).

Out 13 shows that the full or partial lid-shaped closing device can be inserted 5 in an inclined orientation is particularly advantageous because it almost doubles - and thus leads to a considerable increase - of the cooking fume suction capacity towards the open side.

As a result, in the case of devices for extracting cooking fumes according to the invention designed in this way, the efficiency is significantly increased and particularly small, quiet and only very little energy-consuming fan motors are sufficient.

Especially from 14 it can be seen that the complete or partial lid-shaped closing device can be inserted 5 in a vertical or almost vertical orientation is particularly advantageous in terms of preventing the feared sucking in of the gas flame of a gas hob.

From the 15 and 16 it can be seen that the lid-shaped closing device 5 can be formed in two parts or in several parts, the division being perpendicular to the longitudinal axis of the lid-shaped closing device 5 he follows ( 15 ) or is aligned parallel to this longitudinal axis ( 16 ).

This can - as in 15 shown - each part of the lid-shaped closing device 5 at right angles to the longitudinal axis of the cooking vapor inlet device 2nd aligned division only over part of the total length 20 the elongated cooking fume inlet 4th extend and individually from the cooking fume inlet 4th be reversible. Alternatively, each part of the lid-shaped closing device can 5 with parallel to the longitudinal axis of the cooking fume inlet device 2nd aligned division over the entire length 20 the elongated cooking fume inlet 4th extend ( 16 ) and also individually from the cooking fume inlet 4th be reversible.

This cover-shaped closing device which can be lifted off in sections 5 is also advantageous because it almost doubles - and thus significantly increases - the cooking fume extraction capacity to the open side with the lid-shaped closing device lifted off 5 there, leads.

As a result, in the case of devices for extracting cooking fumes according to the invention, the efficiency is significantly increased and particularly small, quiet and only very little energy-consuming fan motors are sufficient.

From the 17th and 19th shows that the cross section of the cooking fume inlet device 2nd in the immediately below the cooking fume inlet 4th located, channel-shaped approach 22 and / or the exhaust air duct 3rd an expansion area 21 can have, in which one or more inclined (to enlarge the flow-through filter surface ( 17th ) or essentially horizontal ( 19th ) aligned, plate-shaped grease filters 9 are reversible.

The advantage of this expansion area 21 in particular also consists in the fact that the flow rate of the extracted cooking fumes in this expansion area 21 reduced and thus the duration of the flowing cooking fumes in one in the expansion area 21 provided grease filter 9 is extended, which increases the cleaning effect of the grease filter 9 is significantly improved.

The desired flow rate of the cooking fumes in the area of the fat filter 9 is preferably in the range from 1.5 m / sec to 2.5 m / sec.

18th shows that in the immediately downstream of the cooking fume inlet 4th located, channel-shaped approach 22 the cooking fume inlet device 2 - without forming a widening area - a plate-shaped grease filter oriented obliquely to enlarge the filter area through which the flow can flow 9 can be provided.

From the 20 to 22 shows that the cooking vapor inlet device 2 - for example to avoid cost-intensive, horizontal flat channels - one or more rear air outlets 23 can have.

Then are preferably in the immediately downstream of the cooking fume inlet opening 4th located, longitudinal channel-shaped approach 22 the cooking steam inlet device 2nd several plate-shaped or strip-shaped, horizontally oriented air guiding surfaces 24th of different lengths spaced from each other in vertical terms, provided.

The 20 to 22 it can be seen that the rear ends of the air guiding surfaces 24th can lie vertically on top of each other and with the rear air outlet 23 the cooking steam inlet device 2nd can be connected in fluidic terms.

The opposite, user-side ends of the air guiding surfaces can then be staggered and offset from one another such that the uppermost air guiding surface 24th the shortest length and the lowest air baffle 24th has the longest length so that the flow velocities of the cooking fume entry device 2nd sucked cooking fumes over the entire length 20 the cooking fume inlet 4th are the same.

The air control surfaces 24th can - when viewed from the side - be straight ( 20 ). As an alternative to this - for aerodynamic reasons, for example - the rear air outlet 23 opposite ends are horizontally curved upwards ( 21 ), curved, curved or kinked ( 22 ) be.

The provision of such air guiding surfaces 24th leads to the advantage that the extraction speed of the extracted cooking vapors over the entire length 20 the cooking fume inlet 4th is roughly the same.

For example, the 1 , 23 and 24th that the extracted cooking vapor through a central air outlet 35 from the cooking steam inlet device 2nd can be led out, the central air outlet 35 - in a plan view - in the region of the center of the total length 20 the cooking steam inlet device 2nd attaches to the side or diagonally below.

In particularly preferred embodiments of the device for extracting cooking fumes according to the invention, the cover frame can 6 be designed as an independent component, which on its underside or on its top side has an air-duct-like extension 22 of the cooking vapor inlet device 2nd or the hanging technology in the exhaust air duct 3rd attachable combination of a short, channel-shaped approach 12th with grease filter included 9 wearing.

Alternatively, the cover frame 6 to the upstream edge of the exhaust duct-like channel-shaped attachment 22 the cooking steam inlet device 2nd or the short channel-like approach 12th the one in the exhaust duct 3rd attachable grease filter combination be integrally formed.

In summary, it should be noted that within the scope of the present invention, a device for extracting cooking fumes in below a hob level 1 pointing direction is provided, which thanks to the lid-shaped closing device according to the invention 5 does not know the problem of the escape of odorous substances from the cooking fume inlet opening even when the fan motor is switched off.

In the case of the cooking vapor entry device according to the invention, the production outlay and the production costs are in particular due to the particularly simple and inexpensive to produce lid-shaped closing device 5 extremely low, so that the cooking vapor entry device according to the invention is particularly suitable for opening up a mass market.

Is particularly advantageous in the case of the lid-shaped closing device according to the invention 5 also their particularly pronounced cleanability.

Especially from 25th The advantage of the device for extracting cooking fumes is evident that, for example, a fully functional kitchen cabinet drawer can be provided at a very short distance below the hob equipped with the cooking fume extractor according to the invention. The device according to the invention for extracting cooking fumes is therefore particularly easy to install in terms of space.
