[0039] A schematic plan view of an embodiment of the combination appliance 1 according to the invention is shown in FIG. 1. The combination appliance 1 consists of a hob 10 and a fume extraction device 11, only the suction opening 111 thereof being able to seen in FIG. 1.

[0040] The hob 10 consists of a cover plate 100 and cooking modules 101 arranged below the cover plate 100. In the embodiment shown, two cooking modules are provided. A cut-out 1000 which forms the air inlet opening 111 is incorporated in the cover plate 100. In the embodiment shown, the cut-out 1000 is incorporated in the center of the width of the cover plate 100 and extends in the depth direction. In the embodiment shown, the cut-out 1000 has a rectangular elongated shape. The length of the cut-out 1000, i.e. the dimension thereof in the depth direction, corresponds to the length of the cooking modules 101. The cooking modules 101 are arranged to the left and right of the cut-out 1000.

[0041] The cooking modules 101 are located below the cover plate 100 and are preferably fastened to the underside of the cover plate 100. Alternatively, the cooking modules 101 may also be held in a hob housing (not shown) and the cover plate 100 is thus applied to the hob housing such that the cooking modules 101 are located in the immediate vicinity or on the underside of the cover plate 100. If a hob housing is provided, said hob housing has a through-opening in the corresponding position of the cut-out 1000.

[0042] An operating unit 103 is arranged in the front region of the hob 10. In the embodiment shown, the operating unit 103 is arranged in front of the cut-out 1000 of the cover plate 100 and may comprise, for example, touch control elements, buttons or rotary knobs.

[0043] Additionally, a display (not shown) may be contained in the operating unit 103. Depending on the design of the individual elements of the operating unit 103, this operating unit may be arranged inside and/or below the cover plate 100. At least the operating electronics (not shown) of the operating unit 103 are arranged below the cover plate 100.

[0044] A schematic sectional view of an embodiment of the combination appliance 1 is shown in FIG. 2.

[0045] The combination appliance consists of the hob 10 and the fume extraction device 11. The combination appliance 1 has an appliance housing 12 in which the components of the fume extraction device 11 and the hob 10 are received. Two cooking modules 101 of the hob 10 are shown, said cooking modules bearing from below against the cover plate 100 of the hob 10 and also being able to be denoted as induction modules. A fastening element 1140 is provided in the cut-out 1000. This fastening element has a removable grille in the cut-out 1000 and extends on the underside of the cover plate 100 laterally beyond the cut-out 1000. The opening of the fastening element 1140, which is located in the cut-out 1000, forms the suction opening 111 of the fume extraction device 11. A filter unit 114 is arranged below the cut-out 1000 and thus the suction opening 111. The filter unit 114 has a grease filter 1141 and two odor filters 115. The construction of the filter unit 114 is described in more detail below with reference to FIGS. 3 to 6. A housing 1142 for receiving the filter unit 114 is fastened at the bottom to the fastening element 1140. The base of the housing 1142 represents a separating plate 1143.

[0046] The blower 110 of the fume extraction device 11 is arranged downwardly spaced apart from the separating plate 1143 on the base of the appliance housing 12. The blower 110 has a blower housing 1100 with an air inlet opening 1101 as well as an air outlet opening 1102 with a grille. The fan wheel 1103, which is driven via the motor 1104 is arranged in the blower housing 1100. The air inlet opening 1101 faces upwardly and the rotational axis of the fan wheel is located in the vertical direction and below the air inlet opening 1101.

[0047] Electronics units 102 and 112 are arranged above the blower 110 laterally adjacent to the filter unit. The upper electronics unit 102 represents the hob electronics unit and the lower electronics unit represents the fume extraction device electronics unit 112. The width of the hob electronics unit 102 is greater than the width of the fume extraction device electronics unit 112. Both electronics units 102, 112 are arranged such that they bear on one side against the appliance housing 12. Thus a shoulder is present on the opposing side of the electronics units 102, 112.

[0048] The suction opening 111 with the grease filter 1141 is shown schematically in FIG. 3. In this view, the suction opening 111 of the fume extraction device is formed by the cut-out 1000 in the cover plate 100 of the hob 10 or, respectively, between the cooking modules 101. The grease filter 1141 in this embodiment consists of two filter elements 11410 which are arranged inclined toward one another and form a V-shape. The undersides of the filter elements 11410 are held in a collection container 1144. The collection container 1144 in the embodiment shown represents an upwardly open rail. The suction opening 111 has a width D1 and the collection container 1144 has a width C. The width C is less than or equal to the width D1. The filter elements 11410 are pivotably fastened to the collection container 1144. As a result, as indicated in FIG. 3 by the double arrow, the grease filter 1141 may be folded up by folding up the filter elements 11410. In the folded-up state the grease filter 1141 may be removed upwardly through the suction opening 111.

[0049] A filter unit 114 with the filter element 114 and the two odor filters 115 are shown schematically in FIG. 4. The grease filter 114 has the construction described relative to FIG. 3. The pivotable mounting of the filter elements 11410 on the collection container 1144 is shown schematically in FIG. 4 by dots. The collection container 1144 and the odor filters 115 are positioned on the separating plate 1143. The odor filters 115 are arranged laterally adjacent to the grease filter 1141. In particular, on each side of the grease filter 1141 an odor filter 115 is offset to the side below the cover plate 100 for the cut-out 1000 which forms the suction opening 111. After the grease filter 1141 has been folded up and removed with the collection container 1144 via the suction opening 111, one of the odor filters 115 on the separating plate 1143 may be pushed in the direction of the suction opening 111 and removed through this suction opening. This is indicated in FIG. 4 by arrows. To this end, the thickness F of the odor filter 115 is less than the width of the cut-out 1000 and the suction opening 111.

[0050] The upper region of the combination appliance 1 is shown schematically in FIG. 5. In this case, the space R is indicated schematically for the arrangement of electronics units, not shown in FIG. 5. In particular, two variants are shown for the possibility of installing the electronics units. On the left-hand side an obliquely running partition wall is shown, relative to which electronics units may be installed to the left. On the right-hand side the space is shown such that in the upper region a wider electronics unit may be installed and in the lower region a narrower electronics unit may be installed. In both variants the spacing between the odor filters 115 or, respectively, the lateral ends of the separating plate 1143 in the lower region (H2) is greater than in the upper region (H1). Additionally, it is shown in FIG. 5 that a spacing G from the blower, not shown in FIG. 5, in particular the air inlet opening of the blower housing, is present below the separating plate 1143. In this spacing G, therefore, the airflow may be conducted from the odor filters 115 to the air inlet opening. The construction of the filter unit corresponds to the construction shown in FIG. 4 and thus is not described again.

[0051] The filter unit 114 of the combination appliance 1 is shown again in detail in FIG. 6. Additionally, the airflow through the filter unit 114 and to the air inlet opening 101 is shown. Additionally, the housing 1142 for the filter unit 114 is shown in this FIG. 6. In the embodiment shown, the separating plate 1143 has a recess 11430 in the center. Additionally, in the embodiment shown the separating plate 1143 forms the base of the housing 1142 for the filter unit 114. The side walls of the housing 1142 in each case are formed by a grille.

[0052] Thus in the embodiment shown the airflow, which is shown schematically in FIG. 6, may enter through the suction opening 111, which is formed in FIG. 6 through an opening in the upper side of the fastening element 1140, into the fume extraction device 11. The air passes through the V-shaped grease filter 1141. The air which has passed through a filter element 11410 passes in the filter unit 114 to an odor filter 115 and passes through this odor filter. After exiting from the odor filter 115 to the side, the air is deflected downwardly and flows between the separating plate 1143 and the upper side of the blower housing 1100 to the air inlet opening 1101 of the blower housing 1100. From there, as shown in FIG. 2, the air is conducted via the fan wheel 1103 to the air outlet opening 1102 and leaves the fume extraction device 11 via said air outlet opening, and also the combination appliance 1 through an opening, not shown, in the appliance housing 12.

[0053] In the present invention, the grease filter is designed to be as large as possible in order to increase the efficiency of the filter and to minimize a flow resistance. In width, the suction opening is defined by the left-hand and right-hand modules. In length, the suction opening is designed to be as long as possible, ideally as long as the depth of the cooking modules. In height, the combination appliance is limited. In particular, the appliance should only be so large that the storage space located below, for example the drawer space, is only used up to a limited extent.

[0054] For this reason the grease filter preferably has a V-shape, wherein the filter is foldable. A sealed container, which may also be denoted as the collection container, is connected to the filter. The width of the collection container is less than the width of the suction opening, in particular the cut-out in the hob.

[0055] The odor filters are preferably mounted outside the foldable grease filter to the left and right thereof. The thickness of the odor filters F in this case is less than the width of the suction opening D1 in the hob. The length of the odor filter may correspond to the depth of the suction opening and is preferably less than the length of the odor filter. However, it is also within the scope of the invention that the odor filter has a greater length than the depth of the suction opening. In this case, the odor filter may be in multiple parts, wherein the individual parts are separately removed through the suction opening. The individual parts in each case have a length which is less than the depth of the suction opening.

[0056] The hob electronics, in particular the printed circuit boards, are generally arranged below the hob in order to gain space, and in the invention the electronics are preferably placed outside the airflow. The spacing H does not have to be necessarily equal over the entire height of the filter. It may be constructed such that H1<H2.

[0057] According to the invention, a separating plate ensures that the air flows through the grease filter and the odor filter and into the blower, which may also be denoted as the fan. A preferred spacing G>20 mm ensures that sufficient air passes to the fan wheel. The separating plate is preferably constructed such that it forms a trough. In the event that liquid flows in, the trough is preferably connected to a separate reservoir. Walls below the trough serve to prevent liquid dropping by capillary action into the air inlet opening and thus into the fan wheel and the motor.

[0058] A grille in the flow direction downstream of the odor filter preferably serves as a stop for the filter and ensures that the user is not able to reach into the motor.

[0059] According to the invention, a separate ventilation system is not installed below the hot plate but a complete combination appliance with both functions (cooking and ventilation) is provided. In this case, preferably only one housing is used.
