Description

Extractor hood for a stove, a hob or the like.

The invention relates to a fume hood for a stove, a cooking area, comprising a housing in which a fan for sucking the Wrasens and a filter for cleaning the exhaust air is arranged by Wrasen, wherein on the housing a pivoting Wrasenschirm for varying the detection area for the vapor on the cooking area is provided.

Extractor hoods are known from the prior art, which are mounted as island extractor hoods on a cooking or over a stove top. Such Island extractor hoods are attached to the ceiling, so that they are freely suspended above the cooking area. Such island extractor hoods can be operated here as recirculation or as exhaust hoods. In the extractor hood according to the invention is based on a recirculation hood, which is also arranged freely suspended over a cooking area. Extractor hoods are known from the prior art, as for example in the EP 1 939 535 is described, which have a Wrasenschirm whose housing is pivotally movable to vary the socket surface above the hob. Another embodiment of the prior art is in the US Pat. No. 4,553,992 described, which is arranged freely suspended over a cooking area, wherein the box-shaped housing has pivotable plates, in order in this way to increase the detection area for the vapor. The embodiment described therein requires that the individual screen elements must be unfolded to obtain in this way a closed hood shape with a conical extent.

The invention thus raises the problem of an extractor hood for a stove to form a cooking further such that the hood should give the kitchen space an improved ambience in its design, taking into account that a sufficient detection surface is given for the Wrasen, the Extractor hood is lightweight and easy to assemble.

According to the invention this problem is solved with the features of the main claim. Advantageous embodiments and further developments of the invention will become apparent from the following subclaims.

The advantages achieved by the invention are seen in the fact that the extractor hood according to the invention assumes a spherical shape in the non-operating state. As a result, the cooker hood in a kitchen above a hotplate does not immediately act as a functional extractor hood, but gives the kitchen ambience the appearance of a lamp. Thus, the extractor hood according to the invention does not interfere, being due to their shape Can be easily and simply attached by means of an electrical supply cable to the ceiling. Thus, in retirement, the cooker hood is a ball, which can also be used as ambient lighting. If boiling surfaces are created, the lower surface opens to a vapor detection screen. The screen consists of several pivotable shell segments, which are designed in two different sizes, here in an inner shade segment and an outer shade segment. Due to the arrangement and size of the umbrella segments, a front operator side can be defined, which allows better accessibility to the hob and a corresponding headroom. Through the opening of the vapor detection screen, the detection range increases in a ratio of 1: 3, where 1 corresponds to the fat filter surface, wherein 3 corresponds to the opened vapor shield. Since the axis of rotation for the umbrella segments are located on the centrally located cutting plane of the sphere, the maximum size of the detection is realized. The spherical shape of the umbrella segments supports the steering of the vapors to the intake, wherein the filter is centrally located, which receives its maximum size in its horizontal position. The individual umbrella segments are simply switched on or unhookable and thus easy to handle. In their respective size, they are easy to clean. To open the vapor detection screen, the entire suction unit, consisting of blower and filter, driven by a certain amount down. The suction unit moves with a peripheral edge against the lever surfaces located on the screen segments. As you move along these surfaces, the screens are pried open by a certain amount. So that the umbrella segments do not interfere with each other when opening, they move with a time delay. This is realized in that the lever surfaces of the respective umbrella segments are at different angles to the Saugansatzeinheit. In the end position, the respective screen segments have different angular positions, so that the screen segments do not collide with each other. The raising or lowering of the suction unit can also be done manually by motor.

According to the teaching of the invention, the housing in the form of a ball, which is divided into an upper, the fan and the filter surface receiving the first hemisphere and in a lower pivotable shell segments existing, the Wrasenschirm forming second hemisphere. In this case, the shell segments are pivotally mounted on the centrally located cutting plane of the ball and advantageously form in the pivoted state, the detection surface for the vapor. According to an advantageous embodiment of the invention, the shell segments are pivotally mounted on a rotation axis, wherein the axes is arranged stationary on the first hemisphere. On the axes of rotation are arranged three inner small shell segments and three outer large shell segments. Thus, in the swung-open state of the shell segments, the inner small shell segments close the spaces between the large outer shell segments. In the pivoted state of the shell segments, the outer large shell elements cover the inner shell segments, wherein the outer shell segments then complete the shape of the ball, thereby covering the inner shell segments.

According to a particularly advantageous embodiment of the invention, each lever elements are arranged on the individual shell segments, which are pivotally mounted on the stationary axes. Here, the lever arms for the differently designed shell segments are also configured differently, so that in particular here due to the angular position of the lever arms first the outer shell segments are extended before then time-delayed extend the inner shell segments and thus close the spaces between the large extended shell segments. Here, as already stated, the individual shell segments are detachably arranged on the stationary axes of rotation. There is thus the possibility that the individual shell segments can be separated from the axes in order to free them from grease residues. Here is also the possibility that the shell elements can be cleaned in a dishwasher.

According to a particularly advantageous embodiment of the invention, the lever elements mounted on the axes of rotation cooperate with their free lever arms with a ring-shaped lowerable or liftable adjusting device arranged in the first hemisphere. As a result of the lowering of the adjusting device, it goes without saying that this also acts as a lever force on the free ends of the lever elements, which then accomplish the pivoting on the stationary axes of rotation. The adjusting device as such, which is accommodated in the first upper hemisphere, in this case comprises a circular filter surface element with a radial fan arranged thereon, so that the entire suction unit is lowered when the shell elements are pivoted open. When the suction unit is raised again, the shell elements pivot back automatically. In this case, the adjusting device can be moved by means of a motor in height. Also, in this case, it is possible to design the actuating device manually operable, wherein the suction unit is adjustable by means of a against the action of a spring in the ball axis arranged grip element in height. Thus, when the suction unit is pulled down on the lever, the shell segments open. According to a particularly advantageous embodiment of the invention, bulbs are arranged on the edge region of the circular housing. In this case, the shell segments can also be made of a transparent material according to a development, so that in particular in the closed state of the ball, the light radiates through the shell segments, and the hood is used as a lamp.

According to a further particularly advantageous embodiment of the invention, the upper portion of the ball or the housing odor filter recordings for odor filter. These odor filter receptacles are preferably removable for cleaning purposes. Due to the segmental design of the odor filter recordings, the individual segments can be cleaned in the dishwasher.

The FIG. 1 shows an extractor hood 1 for a stove or a cooking area, not shown, which includes a housing 2, in which a blower 3, shown in the FIG. 5 , For sucking the Wrasens, as well as a filter 4 is arranged for cleaning the exhaust air of Wrasen. In this case, a pivotable Wrasenschirm 5 is provided on the housing 2 for varying the detection area for the vapor above the cooking area. The upturned vapor canopy is here in particular in the Figures 2 . 4 . 5 and 7 shown closer. Like from the FIGS. 1 . 3 and 6 can be seen, the housing 2 has the shape of a ball 6, which in an upper, the fan 3 and the filter surface 4 receiving the first hemisphere 6.1 and in a lower, from pivoting segments 7.1, 7.2, 7.3 and 8.1, 8.2, 8.3 existing the Wrasenschirm 5 forming second hemisphere 6.2 is divided. As in particular from the FIGS. 4 and 5 can be seen, the shell segments 7.1, 7.2, 7.3 and 8.1, 8.2, 8.3 are pivotally mounted at the centrally located cutting plane of the ball 6 and wherein form in the pivoted state, the detection surface for the vapor, this is particularly in the FIG. 4 to recognize where the hood 1 is shown in the bottom view. The shell segments 7.1, 7.2, 7.3 or 8.1, 8.2, 8.3 are pivotally mounted on axes of rotation 9. From the FIGS. 4 and 5 It can be seen that the axes of rotation 9 in this case is arranged stationarily on the uppermost hemisphere 6.1. On the axes 9, three inner small shell segments 7.1, 7.2, 7.3 and three outer large shell segments 8.1, 8.2, 8.3 are arranged. Like from the FIG. 4 , but also from the FIG. 5 it can be seen where the vapor shield 5 is swung open, close the inner small shell segments 7.1, 7.2, 7.3, the spaces between the large shell segments 8.1, 8.2, 8.3. In the swung state, shown in the FIG. 3 is clearly seen that the outer large shell segments 8.1, 8.2, 8.3 complete the shape of the ball 6 wherein the inner shell segments 7.1, 7.2, 7.3 are covered, which from the FIG. 3 is apparent.

Furthermore, as from the FIGS. 4 . 5 . 6, 7 and 8th can be seen, arranged on the individual shell segments 7.1, 7.2, 7.3 and 8.1, 8.2, 8.3 each lever elements 10 which are pivotally mounted on the stationary axes of rotation 9. In the FIG. 5 but also in the FIG. 6 It can be seen that the lever elements 10 have different angular positions with respect to the shell elements 7.1, 7.2, 7.3 and 8.1, 8.2, 8.3. Here, the lever elements 10 in the embodiment shown here preferably extend for the outer shell segments 8.1, 8.2, 8.3 each with their lever arms at a right angle, wherein the inner shell segments 7.1, 7.2, 7.3 extend with their lever arms preferably at an acute angle. As a result, results in a so-called time-shifted pivoting of the shell segments 7.1, 7.2, 7.3 and 8.1, 8.2, 8.3, here the pivot elements 10 arranged on the outer shell segments 8.1, 8.2, 8.3 first swivel out before then then offset the inside swinging small shell segments 7.1, 7.2, 7.3, which then close the spaces between the large shell segments 8.1, 8.2, 8.3. Depending on the design of the lever elements deviating angular positions of the lever arms are possible from this embodiment.

From the FIGS. 8 and 9 It is clear that the individual shell segments 7.1, 7.2, 7.3 and 8.1, 8.2, 8.3 are arranged detachably on the stationary axes of rotation 9. It goes without saying that when the vapor shield 5 is in the opened position, the individual shell segments 7.1, 7.2, 7.3 and 8.1, 8.2, 8.3 can be separated from the axes of rotation 9 in order then to clean them, for example. In order in particular to control the pivotability of the vapor shield 5 and to perform it simply, the lever elements 10 mounted on the axes 9 cooperate with their free lever arms with an annular lowerable or liftable actuating device arranged in the uppermost hemisphere 6.1. The adjusting device in this case comprises a circular housing 11 with a blower 3 designed as a radial fan 12, which is incorporated in the uppermost hemisphere 6.1 movable. The adjusting device is in this case by means of linear movement, shown in the FIG. 5 , in the Height movable, with the FIGS. 6 and 7 in particular show a further embodiment of the adjusting device, in which case the adjusting device is adjustable by means of a against the action of a spring 13 in the ball axis arranged grip element 14 in height. It now goes without saying that when the handle element 14 is pulled, then the vapor shield 5 opens. Upon pushing back of the handle member 14 then pivots the vapor shield 5 in the closed position, shown in the FIG. 6 ,

According to a particularly advantageous embodiment of the invention, illuminants 15 are arranged at the edge region of the circular housing 11, which illuminate the hotplate, in particular when the canopy 5 is open, wherein with closed canopy 5, the bulbs 15 here have the function of a lamp which hangs over the hotplate. For this purpose, it is then particularly advantageous that the shell segments 7.1, 7.2, 7.3 and 8.1, 8.2, 8.3 can be made of a transparent material.

In the FIG. 9 shown perspective view of the upper hemisphere and the FIG. 11 show that the upper portion of the ball or of the housing 2 has segment-like odor filter receptacles 16. These odor filter receptacles 16 are preferably removable and cover segmental odor filter 17 on the pressure side of the blower third
