Incidentally, it should be noted that the term "cooking zone" can be equated with a known "cooking zone". The term cooking zone is used in particular in induction glass ceramic hobs to designate a surface or portion of the hob surface in which a desired heating of food in pots or pans placed thereon or the like can take place.

In summary, it should be noted that in the context of the present invention, an optimized hob is provided with a device for the extraction of cooking fumes in vertically below the plane of the hob lying direction. Since the hob according to the invention has, in the region of its geometrical center of gravity, a recess which is round or oval or square in plan view for a device for drawing cooking fumes downwards in a direction pointing vertically below the hob, it is now possible for the first time the surfaces located on both sides and rear of the cooktop on the hob carrying worktop for Abstellzwecke or the like are used without restriction. Since the device for the extraction of cooking fumes is now centrally provided in the region of the geometric centroid of the hob, act on the entire surface of the hob sufficiently strong and not canceling against each other Absaugströmungen. As a result, rising and spreading of cooking fumes are safely avoided both in the central region of the hob and in its peripheral areas.

Particular advantages of the hob according to the invention are also to be seen in that its manufacturing, assembly, maintenance and operating costs are particularly low. It is also advantageous in the case of the hob according to the invention that the electrical energy used for the extraction is used particularly efficiently, which is why the efficiency of the hob according to the invention is particularly high.

Another advantage of the hob according to the invention is that the noise is very low during the cooker extraction operation. With regard to the cooking hob according to the invention, designed in the form of a mounting unit with a device, it can be stated in summary that its height is particularly low, whereby the unhindered usable space in the kitchen cabinet is pronounced. Of particular advantage of the invention designed in the form of a mounting unit with a device hob is its compactness and the fact that it can be completely pre-assembled in the factory. As a result, the planning and assembly costs are particularly low. Finally, the completely pre-assembled, compact mounting unit only needs to be inserted into a recess of the worktop, resulting in a particularly quick, easy and inexpensive installation.

By providing two or more radial fans facing each other downstream of the hollow cylindrical grease filter results in a significantly increased effective area of the grease filter and an increase in throughput volume to improve the Fettabscheidegrades and to form a particularly low pressure loss at the larger, effective effective Grease filter surface. This leads to the advantage that the fan motors of the radial fans can be designed to be particularly small, energy-saving, energy-efficient and quiet.

In addition, the speed of the fan motors can be chosen lower, which is why the radial fans used in the invention work very quiet, low-vibration and energy-efficient.

A particular advantage of the hob according to the invention in the form of a mounting unit with a device is that it provides effective protection against and insensitivity to overflowed liquid which has penetrated through the central recess up to a volume of 5 l. Because of the suspension of the fan motors at the bottom of the housing for the control electronics is basically the tub-like volume of the lowest cooking fume suction chamber for receiving overflow liquid to the exclusion of risk to the fan motors available.

The opposite orientation of the directions of rotation 73 according to 15 leads to the advantage that the two cooking fume exhaust streams 69 the downstream of the room 68 for the division and alignment of the blow-off currents 69 provided odor filter 71 indirectly via air ducts 70 or flow directly evenly.

Especially 14 shows that in a plan view of the inside of the hollow cylindrical grease filter 6 located central floor area 74 at least opposite the two sides of this central floor area 74 provided lateral floors 42 the two intake chambers 39 under formation of a stop 75 for the lower edge area 53 of the hollow cylindrical grease filter 6 at least something can be lowered. Furthermore, the central floor area 74 for collecting and collecting overflowed liquid to a central or randwärtigen subsidence 76 be inclined formed. In this case, there is a particularly user-friendly access to the central floor area 74 for cleaning purposes.

A hotplate according to the invention 1 is in schematic view in the 19 shown. Here is a central recess 4 available in the hob area. The hob area is through a front edge 101 , a trailing edge 102 , a left edge 103 and a right edge 104 limited. Usually limit the edges 101 - 104 also the hob 1 per se. And with that, the geometric center of gravity also becomes thereby 3 the hob area defined.

This hob has the central recess 4 in the plane of the cooking surface and is in the illustrated embodiment by an edge 4a limited. The central recess 4 extends only in the area of the geometric centroid 3 , Thus, the recess extends 4 not to the edges 101 and 102 , The central recess 4 has a centroid FL4 of the area centroid 3 the hob area by a certain amount v to the centroid 3 the hob area to the front edge 101 is postponed. This amount v can in particular 2% to 5% of the distance between the front edge 101 and rear edge 102 the hob area amount.

The through the recess 4 limited suction opening has an area of at least 175 cm ² . Here is the radius r of the recess 4 about 10 cm and thus the surface area of the suction port is about 314 cm ² .

On the left side there is a first pair of cooking rings, which is a front left cooking area 2a and a rear left cooking area 2 B includes. The front left cooking area 2a has a geometric centroid FL2a and the posterior left hob has a geometric centroid FL2b. The front left cooking area 2a has a surface area larger than the surface area of the rear left cooking area 2 B , Here is the front left cooker 2a an area that is approximately 50% larger than the surface area of the rear left-hand cooking area 2 B ,

On the right side of the hob 1 There is a second pair of cooking rings, which has a front right-hand cooking 2c and a right rear cooker 2d includes. The front right cooker 2c has a geometric centroid FL2c and the right rear cooking hob 2d has a geometric centroid FL2d. The front right cooker 2ca has an area larger than the area of the rear right cooking area 2d , Here is the front right cooker 2c an area that is approximately 50% larger than the area of the rear right-hand cooking area 2 B ,

In the present embodiment of 19 are also the areas of the front cooking zones 2a and 2c same size. The same applies to the surface area of the two rear burners 2 B and 2d ,

The virtual connecting line of the geometric centroids FL2a and FL2b of the left front cooking point 2a and the left rear cooker 2 B with a vertical on the front edge 101 close here an angle β ₁ , which is here about 10 °. The virtual connecting line of the geometrical centroids FL2c and FL2d of the right front cooker 2c and the right rear cooker 2d with a vertical on the front edge 101 include an angle β ₂ , which is also about 10 ° here. This offset of the cooking zones 2a and 2 B respectively. 2c and 2d allows in combination with the other features an optimized placement and suction, in particular when the respective hob pairs are formed as a unit below the cooking surface area.

In the embodiment shown, moreover, the minimum distances A of the respective edges of the cooking zones 2a - 2d to the edge 4a the central recess 4 same size. The respective distance A is here maximum 60 mm. Preferably, however, the distance is less than 55 mm.

Based on the radius of the central, circular recess 4 is the respective minimum distance A of the outer edges of the cooking zones 2a - 2d at least 40%, in particular 45% smaller than the radius of the recess 4 ,

The in the 19 shown embodiment of a hob according to the invention 1 is in terms of the utilization of the hob surface, the use of different sized pots and pans and the suction through the only centrally existing recess 4 in the hob area of the hob 1 optimized. The combination of the special offset of the rear, smaller cooking rings 2 B and 2d opposite the front cooking zones 2a and 2c and the central arrangement of the recess 4 allowed despite low performance of the suction device effective extraction of the cooking fumes of cookware on all hobs 2a to 2d ,

Finally, it should be noted that a hob, as in he 19 is shown, in addition to the embodiments according to the 1 - 18 can be provided.
