FIG. 1 1 shows a schematic illustration of a domestic appliance 100 according to an exemplary embodiment with the lid 102 set up. The domestic appliance 100, for example a cooker or a device that can be combined with a cooker, comprises a worktop 104 with a recess 106 which is rectangular in form here and serves to remove fumes. The worktop 104 may be, for example, a kitchen worktop for preparing food or a hot plate. In the ready state, the recess 106 is connected to a trigger device, which may be part of the household appliance 100.

The withdrawal device coupled to the recess, also referred to as a depression ventilator, is designed to generate a flow for sucking off the vapor via the recess 106. The cover 102, which also has a rectangular basic shape analogous to the recess 106, serves to cover the recess 106, for example when the trigger device is switched off. The lid 102 is placed adjacent to the recess 106 on its longitudinal side. In this case, the cover 102 extends at least over an entire length of the recess 106. The cover 102 thus acts as a kind of partition wall between the recess 106 and a hob adjacent to the recess 106 can be arranged or arranged.

According to one embodiment, the lid 102 functions as a partition wall between the recess 106 and a portion of the household appliance 100 adjacent to the recess 106, in particular an adjacent hob 107 for heating cookware, such as a gas hob. By means of the cover 102 set up in this way, the recess 106 can be shielded, for example, by gas flowing out of the hob 107. The hob 107 may be integrated into the worktop 104.

In FIG. 1 the lid 102 is placed on one of its two longitudinal edges such that a main extension plane of the lid 102 is aligned substantially perpendicular to a main extension plane of the work surface 104. The lid 102 is magnetically fixed in the erected state on the work surface 104, as described below with reference to FIG. 2 is described in more detail.

According to the in FIG. 1 In the embodiment shown, the cover 102 has a two-layered construction of a cover plate 108 and a cover housing 110, wherein the cover plate 108 covers the cover housing 110. As in FIG. 1 To recognize, the cover plate 108 a at least partially over the cover housing 110 projecting plate edge, which serves as a support surface for placing the lid 102 on the countertop 104, for example.

The cover housing 110 has in the region of two mutually opposite cover ends of the cover 102 each have a slope 112 which is formed according to this embodiment by a sloping housing bottom, d. h., The cover housing 110 is flattened in the region of the two lid ends such that the lid 102 tilted in the inserted state by exerting pressure on one of the two lid ends and thus can be lifted out of the recess 106 on one side. Alternatively, the cover housing 110 instead of the slope 112 also have a rounding or a combination of the slope 112 and the rounding.

The cover plate 108 and the work surface 104 are made of one and the same material, for example. In particular, the cover plate 108 and the work surface 104 may be made of glass ceramic. The lid housing 110 may be made of a magnetically conductive material.

According to the in FIG. 1 In the embodiment shown, the cover housing 110 is realized with two opposite side walls 114 which each extend along a longitudinal edge of the cover plate 108. The two side walls 114 are aligned, for example, substantially perpendicular to a main plane of extension of the cover plate 108 and act as Aufstellkanten for vertical placement of the lid 102 on the countertop 104. The lid 102 is in the erected state, for example via one of the two side walls 114 magnetically on the work surface 104th fixed.

In the recess 106 at least one optional support element 116 is arranged for placing the cover 102, here in the form of a extending over an entire length of the recess 106 strip with two pin-shaped projections 118 which project into the recess 106. The two projections 118, whose number and shape may vary depending on the embodiment, are designed to fix the cover 102 in a defined height in the recess 106 and support. Depending on the exemplary embodiment, the projections 118 are designed to support the cover housing 110 or the cover plate 108, in particular the plate edge projecting beyond the cover housing 118. The support element 116 may be attached to the countertop 104.

According to the in FIG. 1 In the embodiment shown, the support element 116 is arranged at a distance from a surface of the work surface 104 such that a surface of the cover plate 108 in the covered state of the recess 106 is substantially flush with the surface of the work surface 104.

For example, the distance between the support element 116 and the surface of the work surface 104 is substantially equal to a thickness of the cover plate 108, in particular when the cover 102 is held in the covered state of the recess 106 by the over the cover housing 110 projecting plate edge of the cover plate 108.

Optionally, the support element 116 is attached directly to the worktop 104. As a result, a height offset between the cover 102 and the work surface 104 can be reduced to a minimum due to manufacturing tolerances. It is advantageous if the working plate 104 and the cover plate 108 have substantially the same thickness.

FIG. 2 shows a schematic representation of a household appliance 100 FIG. 1 with covered recess 106. According to this embodiment, the lid 102 has a first lid magnet member 200, a second lid magnet member 202, a third lid magnet member 204, and a fourth lid magnet member 206. The four lid magnet elements are arranged in pairs opposite one another on the two side walls 114 within the lid housing 110. Similarly, a first countertop magnetic element 208, a second countertop magnetic element 210, a third countertop magnetic element 212, and a fourth countertop magnetic element 214 are integrated into the countertop 104 with the four countertop magnetic elements disposed adjacent the recess 106. In this case, the two worktop magnet elements 208, 210 adjacent to a first longitudinal side of the recess 106 and the two worktop magnet elements 212, 214 adjacent to a second longitudinal side of the first longitudinal side opposite the recess 106 are arranged.

In the covered state of the recess 106, the two lid magnet elements 200, 204 and the two worktop magnet elements 208, 212 arranged substantially at the same height, which is indicated by a first dashed line 216. The remaining magnet elements 202, 206, 210, 214 are arranged in an analogous manner along a second dashed line 218.

Depending on whether the cover 102 is placed on a portion of the work surface 104 adjacent to the first longitudinal side of the recess 106 or a portion of the work surface 104 adjacent to the second longitudinal side of the recess 106, in the erected state of the cover 102, either the first cover magnetic element 200 and the first worktop magnet element 208 and the second lid magnet element 202 and the second worktop magnet elements 210 or the third cover magnet element 204 and the third worktop magnet element 212 as well as the fourth cover magnet element 206 and the fourth worktop magnet elements 214. Here, the lid 102 is magnetically held by the mutual attraction between the respective opposing magnetic elements on the work surface 104.

Alternatively, as already mentioned, the lid housing 110 may be made of a magnetically conductive material, so that the lid housing 110 is held in the erected state by the magnetic force of the countertop magnetic elements. Here, the cover magnet elements can be omitted. Conversely, the work surface 104 may be realized at least in the area of a footprint for setting up the lid 102 of a magnetically conductive material, wherein the lid 102 is held in the erected state by the magnetic force of the lid magnet elements. In this case, the worktop magnetic elements can be omitted.

The lid and worktop magnetic elements described above are, for example, permanent magnets.

FIG. 3 shows a schematic representation of a household appliance 100 according to an embodiment with the lid 102. The in FIG. 3 Household appliance 100 shown substantially corresponds to the above with reference to the FIGS. 1 and 2 described domestic appliance, with the difference that the cover 102 in addition to the cover housing 110 has a further cover housing 300. The two cover housing 110, 300 are spaced from each other on the cover plate 108, wherein they extend in its longitudinal direction substantially transverse to a longitudinal direction of the cover plate 108. In this case, the cover 102 is ever placed on a narrow side of the two cover housing 110, 300. Opposite the two narrow sides is in each case one of the worktop magnet elements, here by way of example the first worktop magnet element 208 and the second worktop magnet element 210, wherein the entire cover 102 can be made of the two narrow sides, which can be made of a magnetically conductive material, and those with the material of the narrow sides magnetically interacting worktop magnet elements 208, 210 are fixed to the worktop 104.

On an opposite side of the support 106 of the recess 106, an optional further support element 302 is arranged. The two support elements 116, 302 are designed here strip-shaped and mounted on a side facing away from the cover 102 side of the countertop 104 that they project at least partially into the recess 106. The two cover housings 110, 300 are positioned relative to the two support elements 116, 302 on the cover plate 108 such that the two support elements 116, 302 are arranged in the covered state of the recess 106 between the two cover housings 110, 300, as shown in FIGS FIGS. 4 and 5 is shown.

By at least one additional magnetic element, here by way of example the first worktop magnet element 208, the cover 102 can be fixed and stabilized in the suspended state. For this purpose, the cover plate 108 is at least partially magnetically conductive. In FIG. 18 For example, the top plate 108 is attached to the countertop 104 via the third top plate recess 1804. This corresponds to an uppermost position of the lid 102, in which the lid 102 protrudes maximally over the recess 106.

FIG. 19 shows a schematic representation of a household appliance 100 FIG. 18 , The cover 102 is fixed here via the first cover plate recess 1800 at the edge of the recess 106. This corresponds to a lowermost position of the lid 102, in which the lid 102 is largely sunk in the channel 500.

FIG. 20 shows a schematic representation of a household appliance 100 FIG. 18 , The cover 102 is fixed here via the second cover plate depression 1802 at the edge of the recess 106. This corresponds to a lying between the first and second position middle position of the lid 102nd

Hereinafter, various embodiments of the present invention will be described with reference to FIGS FIGS. 1 to 20 again described in other words.

A bowl ventilator of the household appliance 100 should, when switched on, aspirate as much vapor as possible through a gap as large as possible and, when not in use, optically integrate into the living environment of the kitchen. When combining a bowl-type blower with a gas appliance, additional shielding is typically required to prevent the gas from being drawn into the bowl ventilator prior to ignition.

The lid 102 in this case may function as a shielding plate for shielding the gas. When the household appliance 100 is switched off, the lid 102 is located flush with the surface on the well ventilator in order to completely close the recess 106, in particular in a fluid-tight manner.

The lid 102 is made of magnetic stainless steel, for example. Alternatively, the cover 102 can be made of plastic, steel, glass ceramic or a composite material.

The lid 102 may have an L-shaped folded edge 900 with a magnet or a magnetic material.

By simple, lateral pushing with a finger or other opening mechanism, such as a push-pull mechanism, or by magnetic force, the lid 102, which is L-shaped in this example, can be removed. Now the household appliance 100 can be started and it can be sucked out fumes.

For example, the lid 102 is formed to be inserted centrally in the recess 106 in a groove, also referred to as cover plate recess above.

In the case of a combination of the tray ventilator with a gas appliance, the lid 102 should be attachable laterally to the tray ventilator. For this purpose, the L-shaped side is directed down on the lateral edge of the recess 106. By means of at least one magnetic element, the lid 102 is fixed there. The magnetic elements are either on a side facing away from the cover 102 side of the work surface 104, d. H. Below a device margin, in the household appliance 100 or arranged on the L-shaped fold 900.

Alternatively, the lid 102 may also be designed T-shaped. When not in use of the tray ventilator, the lid 102 rests flush on the household appliance 100. Here, the web can be directed up or down. If the web is directed upwards, then the web can also be used as a handle for the cover 102. In the active state of the household appliance 100, the lid 102 can be hung laterally in the shaft 500, also called channel, and fixed by means of a magnet. The web rests on the edge of the recess 106 and prevents the lid 102 from slipping.

As a further alternative, the lid 102 may be realized with different grooves 1800, 1802, 1804 in different positions. These allow a flush mounting and mounting in different positions on the side of the shaft 500 in the active state. Optionally, the lid 102 is held by at least one magnet.

Such a hollow ventilator offers the advantage of a simple magnetic mechanism, a defined lid position, a simple cleaning, a comfortable handling, ie an ergonomic operation, a high-quality, homogeneous optics and a relatively inexpensive production.

FIG. 21 shows a schematic representation of a household appliance 100 according to an embodiment. The domestic appliance 100 is realized with a cooking-steam inlet element 2100, which is part of a take-off device arranged in the worktop 104 or in a cooktop. Here, the recess 106 serves as an opening for the cooking vapor. Therefore, the recess 106 may also be referred to as a cooking vapor inlet opening.

With manually manageable covers of trough blowers can escape through a cooking fume inlet opening up odors. This can be avoided that the recess 106 by means of the lid 102 is fluid-tight and thus odor-proof closed, such as when not in use of the tray ventilator. The recess 106 is thus completely coverable by the cover 102.

According to one exemplary embodiment, the recess 106 can be covered by the cover 102 in such a way that the cover 102 is flush with the work surface 104 in the closed state, ie. H. as little as possible above the worktop 104 is raised.

The cooking vapor inlet element 2100 comprises a frame 2102 and a bearing edge 2104 which completely surrounds the recess 106 and forms a bearing surface for laying the lid 102. The support edge 2104 is part of the frame 2102. The frame 2102 may be realized as part of the countertop 104.

For this purpose, the support edge 2104 according to one embodiment, an inclined recess 2106, which is covered by the lid 102 in the closed state. The recess 2106 is in this case, for example, against a first narrow side of the lid 102. For lifting the lid 102, the user exerts on a depression 2106 opposite side of the lid 102 a force 2108 and pushes it down into the recess 2106, whereby one of first narrow side opposite the second narrow side of the lid 102 in the direction of an arrow 2110 is raised.

Alternatively, the removal of the lid 102 by means of a mechanical or magnetic support, as described below with reference to Figures 22 and 23 is described. This is, for example, a device which is designed to lift the cover 102 on at least one side or corner so far that the user can easily grip the cover 102. With multiple lids, the household appliance 100 may include a plurality of such devices corresponding to a number of the lids. The Lifting of the lid 102 takes place either by means of a pin or lever movable relative to the recess 106 or by means of at least one magnetic element.

FIG. 22 shows a schematic representation of a household appliance 100 according to an embodiment. The household appliance 100 essentially corresponds to a preceding with reference to FIG. 21 described household appliance. In contrast to FIG. 21 where the lid 102 can be removed by manual lifting, the in FIG. 22 shown domestic appliance 100 a lifting device 2200 for lifting the lid 102 on. According to this exemplary embodiment, the lifting device 2200 comprises an adjusting element 2202, which is displaceably arranged in the supporting edge 2104, in particular between the recess 106 and a gasket, not shown here, which surrounds the recess 106 completely. A displacement direction of the actuating element 2202, which is formed for example as a pin or lever, is marked with a double arrow.

The displacement of the actuator 2202 is triggered by a particular event. Here, the adjusting element 2202 moves upward in the direction of the lid 102, whereby it is raised so far that it protrudes at least partially over the recess 106.

According to this embodiment, the lifting device 2200 is realized as a latching mechanism with at least one spring 2204 for acting on the actuating element 2202 with a spring force. A detent lock of the detent mechanism is unlockable, for example, by exerting a pressure on the cover 102, whereby the spring force is released. Alternatively, the lifter 2200 includes an actuator configured to electromechanically or magnetically move the actuator 2202. The actuator is realized, for example, as an actuator or motor. The adjusting element 2202 is realized, for example, as a translationally movable piston or as a lever which can be rotated or pivoted about a fixed axis. Alternatively, the actuator 2202 is configured to perform a combination of translational and rotational movements. The provision of the actuator 2202 can be done manually or automatically.

Due to the mechanical support by means of the adjusting element 2202, the cover 102 can be raised in a controlled manner to a defined distance from a closed position. As a result, the user is facilitated the gripping of the lid 102. If the lifting of the cover 102, for example by means of magnetic force, such as by means of an electromagnet, which can lift the lid 102 defined, so this has the advantage that the lifting device 2200 is protected from dirt and mechanical damage.

The lifting of the lid 102 is carried out automatically or semi-automatically depending on the embodiment. In this case, the lid 102 is activated by driving the lifting device 2200 only raised when, for example, by means of a corresponding sensor 2206 a triggering event is detected. The triggering event may be, for example, a touch of a surface of the lid 102. To exclude unwanted operating errors, the sensor 2206 may be designed to detect a specific movement pattern, for example capacitively. The triggering event may also be a knock, which may be detected by an acoustic sensor or an acceleration sensor. Further triggering events may be switching on the household appliance 100 or actuating an operating element of the household appliance 100.

FIG. 23 shows a schematic representation of a household appliance 100 according to an embodiment.

The lifting device 2200 thus includes no moving parts. This facilitates cleaning and increases the service life and reliability of the lifting device 2200.

The actuator 2202 in the form of the electromagnet is designed to lift the cover 102 by means of magnetic force when switched on. Optionally, the lifting device 2200 comprises at least one additional holding magnet element 2300, here a permanent magnet. The adjusting element 2202 and the holding magnet element 2300 are, for example, aligned with each other in opposite directions. Here, the actuator 2202 is formed to generate a stronger magnetic field than the magnetic holding member 2300. By the holding magnet element 2300, a secure positioning of the cover 102 and an odor-tight closing of the recess 106 is ensured in the deactivated state of the actuating element 2202.

The actuator 2202 and the holding magnet 2300 may be integrated into the frame 2102. In particular, the actuating element 2202 and the holding magnet element 2300 may be arranged adjacent to the supporting edge 2104 and thus protected by the inserted cover 102 from dirt or damage.
