Description

The invention relates to a fume extraction device with a Wrasenschirm, in particular a Inselesse.

Especially in modern kitchens, island food is used to extract fumes and vapors from a cooking area. This type of fume extractor is attached to the ceiling and is accessible or visible from all sides. In order to give the Inselesse an elegant appearance, this consists in the upper area of a fume hood, which is usually designed as a fireplace. In the bottom of the extractor housing, the suction port is arranged. In order to increase the vapor capture rate, a vapor shield is provided at island eating. This surrounds the suction port and is formed of a plate. Such Inselesse is for example in the DE 103 49 675 A1 described.

A disadvantage of the known island food is that in order to ensure a sufficient vapor capture rate, the dimensions of the vapor shield must be large. As a result, the headroom of the user is significantly impaired. If the vapor shield is made of an opaque material, the insight into the cooking area can also be obstructed or impeded.

The object on which the present invention is based, therefore, is to provide a fume extraction device which overcomes the disadvantages of the prior art and nevertheless ensures a sufficient vapor capture rate.

This object is achieved by a fume extraction device with a fume hood and a arranged at the bottom of the extractor hood Wrasenschirm, which protrudes at least over the front and back of the extractor housing. The extractor device is characterized in that the vapor shield has a central part and at least one front and at least one rear pivotable segment.

The extractor device referred to in the context of this invention is a so-called Inselesse. In this extractor device all side surfaces of the extractor device are outsides, that is, do not lie against a room wall, as is the case with wall foods. Island meals are usually attached to the ceiling via the extractor housing, which is also called the fireplace at Essen. As Wrasenschirm a flat element is referred to the fumes and fumes, which flow from the bottom of the extractor device hit. For this purpose, the vapor shield extends, as a rule, at least partially in the horizontal direction. In addition, the vapor shield can also serve to direct fumes and vapors to an intake opening of the extractor device or at least to keep it in the region of the intake opening.

The vapor canopy is provided according to the present invention at the bottom of the extractor housing. The vapor shield may in this case be directly adjacent to the suction opening or mounted above the underside of the extractor housing on the outside thereof.

By protruding at least over the front and the back of the extractor housing in the extractor device according to the invention, the risk that Wrasen on the front of the extractor housing or the back sweeps past minimized.

As the front of the extractor device and the extractor housing, the side is referred to, which faces the user in the assembled state. In particular, this is the side that faces the user when using a cooker or hob provided below the extractor device. On the front of the hood therefore controls are usually provided for operating the extractor device. As the back of the extractor device, the opposite side of the front of the extractor device is called. In extractor devices which can be operated from two sides, that is, which has two operating sides, one operating side is referred to as the front side and the opposite operating side as the rear side. The front and back sides thus preferably designate the sides of the extractor device, in the assembled state with the front edge and the rear edge of a provided under the extractor device work surface in which the hob can be provided, are aligned. In the case of so-called open kitchens, for example, the front side may face the kitchen and the rear side may face a room adjoining the kitchen, for example a dining room.

By protruding beyond the front side and the rear side of the extractor housing in the extractor device according to the invention, annoying the user when operating the extractor device can already be at least partially avoided. In addition, escape of fumes, for example, in an open kitchen, in an adjacent room can be largely avoided.

The central part of the vapor shield may constitute a holder for fixing the vapor shield to the extractor housing, in which case the central part may be a frame or the like. Preferably, however, the middle part is a planar element that at least partially surrounds the suction opening of the extractor device or the extractor housing in which the suction opening is provided.

Since the vapor shield of the extractor device according to the invention consists of three parts, of which the front and the rear segment are pivotable, on the one hand the surface of the vapor shield in the depth direction of the extractor device can be maximized. In addition, by appropriate positioning, that is, pivoting of the segments, below the Mitteil a trap space can be formed. Finally, the pivoting of the front or the rear segment also allows the movement of the segments from the field of view of the user of the extractor device. By the segments are pivotable and thus movable, their position or position can be adapted to the currently prevailing conditions around the extractor device and the current requirements of the extractor device accordingly. The flexible adjustable shape of the extractor device according to the invention thus a better Wrasenabsaugung is possible. The segments or wings can serve as air guide elements and individually in their position and / or inclination optimally steer the ascending in the front and rear areas fumes to the intake of the extractor device.

It can thus be a better as well as more extensive extraction of the rising Wrasens.

In addition, the appearance of the extractor device is improved by the pivotable segments. Compared to a fume extraction device, in which the surface for Wrasenführung is provided only by a horizontally extending vapor shield, the depth of the extractor device according to the invention can be at least temporarily reduced by pivoting the segments. The extractor device therefore appears less voluminous.

The pivotable segments of the vapor shield are preferably plates or strips of material. The segments are designed so that they can serve to conduct air along the surface thereof. In particular, the segments are therefore made air-impermeable.

The size, that is to say in particular the depth of the segments, is chosen such that, when the segments are pivoted downwards, the height of the vapor collecting space defined by the latter and the middle parts is sufficiently great to improve the vapor capture rate of the extractor device. The depth of the segments is small compared to the depth of the middle part. For example, the depth of the segments may correspond to half the depth of the central part. In one example, the depth of the middle section is 60cm and the depth of the segments is 20cm to 30cm each. However, the present invention is not limited to specific dimensions of the individual parts of the vapor shield. Due to the relatively small size of the segments, the weight of the segments is kept low and pivoting of the segments can therefore be done manually in a simple manner. In addition, a small depth of the segments means that they do not unnecessarily impair the view of a cooking point provided below the extractor device even when folded down.

Advantageously, the front and the rear segment are movable independently of each other. This allows an even more individual adaptation of the segment position to the conditions prevailing in the environment of the extractor device.

Preferably, at least one segment at the front edge of the central part and at least one segment are pivotally mounted on the rear edge of the central part. The front edge is the edge of the central part, which faces the user of the extractor device. The trailing edge represents the opposite edge of the middle part. The advantage of the mounting of the segments on the front edge and the rear edge is, above all, that they can be pivoted relative to the middle part over a large angular range. In particular, the segments can be pivoted both downwards and upwards relative to the middle part. This is not possible with segments which would be attached to the underside of the middle part or another part of the extractor device.

The width of the vapor shield is preferably greater than the width of the extractor housing. For example, the canopy may have a width of 90cm or 120cm. The width here is the dimension of the vapor shield or the extractor housing, which extends horizontally in a front view of the front of the extractor device. By the width of the vapor shield is chosen to be greater than the width of the extractor housing, the area which is available for catching or passing of vapors is increased compared to the pure suction opening in the bottom of the extractor housing. To the sides of the extractor device, a worktop is usually provided below the extractor device. Due to the large width of the vapor can thus also vapors, for example, from a pot that has been placed next to the hotplate, collected. The enlargement of the area of the vapor shield in the width direction brings no disadvantages for the user, since it does not approach the extractor device from the side and thus is not obstructed by a vapor shield projecting over the worktop.

The at least one segment can preferably be pivoted up to the surface of the middle part in the installed position with respect to a horizontal position by an angle α in a range from -180 ° upwards to 90 ° downwards. But it is also possible to limit the movement of the segments to another area. For example, the movement may be limited to the range of -90 ° to 90 ° or -90 ° to 60 °. The angle α from the horizontal in Extension of the underside of the central part of the vapor shield to the underside of the segment spanned.

It is of course also possible that the segment is pivotable over a larger range of, for example, -180 ° to 180 ° relative to the surface of the central part. However, special demands are placed on the holder or storage of the segments. In addition, the effect of the segments as the front and rear boundary of a vapor collecting space decreases from a pivoting of the segments of more than 90 °. At 90 °, however, the achievable with the segments largest, especially highest vapor trapping space is defined. By pivoting in the range of 90 ° to 0 ° with respect to the central part, although the height of the vapor collecting space decreases, the depth of the vapor collecting space, that is to say the dimension in the depth direction of the extractor, is increased. At 0 °, the segments lie in the plane of the middle part and form with this the maximum achievable surface of the vapor shield. By pivoting in the range between 0 ° and - 90 °, that is, with respect to the middle part up, the user can depending on his height free access to a located below the extractor hob or worktop procure. In addition, by the folding up of the segments, in particular of the at least one front segment, devices which are provided, for example, at the front of the extractor housing in the region of the lower end, can be made accessible. These devices may be, for example, controls and display devices of the extractor device. Preferably, the segments are limited upwards in their freedom of movement to a pivoting by -90 °. This limitation, which can be realized by stops in the holder of the segments or separate stops, brings with it the advantage that the segments can easily be moved again due to gravity, in particular can be pivoted downwards.

Particularly preferably, the position of the segments is freely selectable by the user. This can be realized by Reibhemmungen or other fixing devices. Alternatively, different positions of the segments may be predetermined by locking in or on the holder of the segments. The segments can be due to the detent to the middle part gradually from its horizontal position by different angles α up / down to be movable.

The latching or the latching element can be designed so that this specifies different angular positions of the segments and offers the user a choice of preferred angular positions of the segments.

Preferably, the width of the at least one segment corresponds to the width of the central part of the vapor shield. With a position of the segments with respect to the middle part of 0 °, this makes it possible to deliver a surface of constant width over the entire depth of the vapor shield. Moreover, it is advantageous if the width of the middle part corresponds to the width of the segments, since, when the segments are folded down, a vapor collecting space is defined over the entire width of the middle part. Of course, it is also within the scope of the invention that the segments have a smaller width than the central part of the vapor shield. In this case, preferably a plurality of segments adjacent to each other at the front and / or the back are provided. These can be moved separately from each other and it can for example be viewed in different areas below the vapor shield without the vaporizing chamber is canceled in another area. In addition, smaller width segments can be easily moved by the user due to the lower weight.

The at least one front segment and / or the at least one rear segment is preferably connected via a separate joint to the middle part of the canopy. In particular, the hinge may be a hinge or another hinge. By the hinge is designed as a separate unit, the central part and the segments may have a simple structure and be designed for example as a simple plates. Furthermore, the material of the segments and the middle part can be chosen differently by this modular design of the vapor shield. For example, the middle part may be a stainless steel plate or a layer construction, while the segments or at least one of the segments may be made of glass.

Preferably, a fixing device or inhibition is provided in the joint. Through this inhibition, the individual segments can be brought into the desired position and held there. By the fixing device or inhibition is provided in the joint itself, the central part and the segments may have a simple structure and represent, for example, simple plates.

The materials from which the vapor shield can be made are not limited to any particular materials. The individual parts of the Wrasenschirms may for example consist of stainless steel, aluminum or glass. In this case, it is also possible that the middle part consists of a different material than the segments. Also, the front and the rear segment can be made of different materials.

The canopy extends over the front, over the back and over both side walls of the extractor housing. It is thus an Island Fairy, which is attached to the top of the extractor housing on a ceiling. These can be located both in front of the front and in front of the rear, where the pivoting segments are arranged.

FIG. 1 shows an embodiment of the hood according to the invention 1. The hood 1 is an island fair and consists of a Extractor hood 10 in the form of a chimney and a arranged at the bottom of the extractor housing 10 vapor shield 11. In the extractor housing 10, a fan blower (not shown) is provided. In the bottom 104 (see FIGS. 4 and 5 ) of the extractor housing 10, a suction opening (not shown) is provided, are sucked through the fumes and vapors by means of the ventilation fan in the extractor housing 10. The suction port is covered by a filter element (not shown). The vapor shield 11 is provided at a distance to the bottom 104 above the bottom 104 on the extractor housing 10. In the area between the lower side 104 and the vapor shield 11, for example, operating elements 12 or displays may be provided, which will be described later with reference to FIG FIGS. 4 and 5 will be explained in more detail.

The vapor shield 11 comprises, in the illustrated embodiment, a horizontally disposed plate which constitutes the middle part 112 of the canopy 11. At the front edge 1121 and the rear edge 1122 of the middle part 112 pivotable segments 114, 115 are provided as air guide surfaces. These segments 114, 115 are each pivotably connected to the middle part 112 via a hinge 113 or hinge. The segments 114, 115 likewise constitute plates or plate strips. The pivot axis of the joints 113 in this embodiment lies in the front edge 1121 and the rear edge 1122 of the central part 112 of the canopy 11.

In the illustrated embodiment, the extractor housing 10 is formed by a chimney having a rectangular cross-section. Here, the width of the front side 101 and the back 102 of the extractor housing 10 is greater than the width of the side walls 103 of the extractor housing 10th

In the lower region, the extractor housing 10 is surrounded by the central part 112 of the vapor shield 11. The width of the middle part 112 in the illustrated embodiment is greater than the distance between the front edge 1121 and the rear edge 1122 of the middle part 112. The middle part 112 thus has a greater width than depth.

The front edge 1121 of the Mitteilteils 112 is covered over its entire length by a hinge 113 which is formed in the form of a hinge. About the Joint 113, the segment 114 is held on the Mitteilteil 112 of the Wrasenschirms 11 and can be pivoted relative to the Mitteilteil 112. At the rear edge 1122 of the middle part 112, a further segment 115 is connected in a corresponding manner to the middle part 112 via a hinge 113.

In the in FIG. 1 shown first position of the extractor device 1, the front segment 114 relative to the horizontal, in which the middle part 112 extends, by an angle α pivoted downwards. By contrast, the rear segment 115 is pivoted upward by an angle α relative to the horizontal.

The angle α is spanned between the horizontal in extension of the underside of the middle part 112 and the underside of the segment 114, 115. In the case of the downwardly inclined segment 114, 115, the angle α assumes positive values, and with the angle α inclined upward, negative values.

In FIG. 2 another possible position of the embodiment of the extractor device 1 is shown. In this position, the segments 114, 115 with respect to the central portion 112 are both pivoted downwards and are at a right angle to the horizontal and thus to the central portion 112. In this position, a Wrasenfangraum is formed around the suction opening in the bottom 104 of the extractor housing 10 bounded by the underside of the central portion 112 and the bottoms of the segments 114, 115 facing each other in this position.

In FIG. 2 is below the Wrasenschirms 11 is a stove 2 and a surrounding worktop 3 shown. With regard to the width of the vapor shield 11, the vapor extraction device 1 projects beyond the hearth 2 arranged below the vapor extraction device 1 to both outer sides. The depth of the middle part 112 of the canopy 11 in the illustrated embodiment corresponds to the depth of the hearth 2. However, it is also possible that the middle element 112 has a smaller depth. An overhang over the front and back of the hearth 2 is achieved by the segments 114, 115. In this case, the free ends 131 of the segments 114 and 115 project beyond the front and rear of the hearth 2 in FIG FIG. 3 The downwardly inclined position of the segments 114 and 115. The depth of the segments 114 and 115 is less than the depth of the central portion 112th

By means of the vapor collecting space formed below the middle part 112, escape of vapor via the front or rear side of the vapor shield 11 is reliably prevented and, in addition, the vapor capture rate is improved.

In FIG. 3 another possible position of the embodiment of the extractor device 1 is shown. In this position, the segments 114, 115 with respect to the central portion 112 are both pivoted downwards at an angle α relative to the horizontal. The angle α is 45 °. The angle by which the segment 114 or 115 is pivoted downwards relative to the middle part 112 is thus smaller than that in FIG FIG. 2 shown angle α of 90 °. As a result, the segments 114, 115 project beyond the front edge 1121 and the rear edge 1122 of the central part 112. The surface on which substantially perpendicularly rising upwards rising fumes and vapors, therefore, is greater than the underside of the central portion 112. Since the segments 114, 115 but also pivoted in this position from the horizontal down, is also in this position defines a vapor trap. As a result, the vapor capture rate of the extractor device 1 can be further increased.

In the FIGS. 4 and 5 Finally, another possible position of the segments 114 and 115 of the extractor device 1 is shown. In this position, the front segment 114 is pivoted upwards relative to the middle part 112 and the rear segment 115 faces downwards. By pivoting up the headroom of the user can be increased. In addition, an optionally obstructed by a folded down segment 114 insight on the stove 2 by the folding of the segment 114 can be ensured. By the rear segment 115 continues to project downwardly, at least to the rear of a vapor collecting space is limited.

In the illustrated embodiment of the extractor device 1, controls 12 are provided on the front side 101 of the extractor housing 10 in the lower region. These are located on the front side 101 between the bottom 104 of the extractor housing 10 and the underside of the central portion 112 of the Wrasenschirms11. By pivoting the front segment 114 upwards, the lower region of the front side 101 of the extractor housing 10 is accessible to the user. Thus, access to the controls 12, which are arranged in this area, free. The operating elements 12 can serve to operate the extractor device and optionally to operate lighting devices (not shown) on the extractor device 1. In addition to the operating elements 12, display devices can also be provided in this area.

The segments 114 and 115 can be brought into the desired positions by the user of the extractor device. In the joints 113, escapements are preferably provided which hold the segments 114, 115 in the position in which the user has brought them.

The present invention thus provides an island fair in which the vapor shield can be designed as a simple plate, which can consist for example of glass or of a sandwich material. The plate is divided into three segments and connected by means of swivel joints. The outside, that is, the front and rear segments can be changed by the user by turning in the position opposite the central part. The rotational movement or fixation of the segments is realized by means of inhibition in the joint.

The invention has the advantages that the user can easily adapt the vapor trap of the extractor device or produce such. As a result, in particular the open position in the area given in the case of island food, which has a negative influence on the suction behavior and the catch rate, can be taken into account. In addition, the look of the Inselesse can be designed or changed by the user. Finally, the Inselesse is easy to use, since the adjustment of the wings can be done directly, plausibly and without technical detours, such as switches or motors.
