Description

Extractor hood and filter for extractor hood

Technical area

The present invention relates to an extractor hood according to the preamble of claim 1.

State of the art

A trained for mounting on a kitchen stove extractor hood with a fold-out hood is known for example from the document DE 1 702 825 U1. This hood has a quarter-circle-shaped profile in the unfolded state. For deriving kitchen fumes, the hood is connected by means of a connecting pipe with a stovepipe. Functional elements such as a fan, a filter mat or a lighting device are not provided. In the absence of a fan, this extractor hood at best has a weak suction effect for sucking the mist into the hood.

From the document DE 80 26 403 U1 an extractor hood with two fold-out, quarter circle-shaped Wrasenschürzen is known. These fumes aprons are arranged in the unfolded state of the side of the housing of the hood and serve to support the suction of a fan of the hood. For example, when not in operation of the hood, the fumes aprons can be completely pivoted into the housing. The mounted on a wall housing this hood is rectangular and includes the functional elements of the hood, namely the blower, a filter mat and a lighting device. A disadvantage of this hood is that the housing with the functional elements is box-shaped and thus occupies a relatively large amount of space. An extractor hood according to the preamble of claim 1 is known from the document DE 103 46 716 A1. Furthermore, this document DE 103 46 716 A1 discloses various forms for the housing of the extractor hood. Thus, the housing may be formed, for example, in the manner of an isosceles triangle or wedge-shaped. Also variants of the wedge shape are described. Thus, the front surface or suction surface of the wedge-shaped housing can be straight, convex, concave or even angled. A disadvantage of the disclosed in the document DE 103 46 716 A1 housing forms, however, is that they occupy a relatively large amount of space.

DESCRIPTION OF THE INVENTION: Problem, Solution, Advantages

Based on the disadvantages and inadequacies set out above and in appreciation of the state of the art outlined, the present invention has the object, a fume hood of the type mentioned in such a way that the housing of the hood is designed to be as compact as possible. In particular, the fan or the fan should be arranged with as little space in the housing.

This object is achieved by an extractor hood with the features specified in claim 1. Advantageous embodiments and expedient developments of the present invention are characterized in the subclaims.

Thus, the present invention is based on the fan being located within the quadrant profile of the housing. This form of housing is the most compact envelope of the functionally substantially circular or circular fan. Due to its compact housing shape, the extractor hood according to the invention is particularly space-saving and has a discreet visual appearance.

According to an advantageous embodiment of the present invention, the first radial surface is substantially perpendicular or substantially aligned in the vertical direction, for example attached to a wall. The arranged at right angles to the first radial surfaces second radial surfaces, however, is advantageously in the Essentially horizontal or substantially aligned in the vertical direction. The two radial surfaces or legs of the housing are due to the quarter-circle-shaped profile of the housing substantially the same length.

Furthermore, due to the quarter-circle-shaped profile of the housing, the front surface or visible surface

- At its first radial surface facing the lower end or lower portion substantially at ninety degrees angle to the first radial surface and

- Oriented at its upper end or upper area facing the second radial surface substantially ninety degrees angle to the second radial surface. Preferably, the lower end of the front surface is thus arranged substantially horizontally or in the horizontal direction or in the vertical direction and arranged the upper end of the front surface substantially perpendicular or in the vertical direction.

The hood can be arranged over a cooking area, such as a kitchen stove, and serve to remove the resulting cooking turfs or cooking fumes. For example, for illuminating the cooking area, the extractor hood may preferably have at least one illuminant at the lower end of the front surface. Such a luminous means may in particular be at least one incandescent bulb, at least one halogen lamp, at least one fluorescent tube or at least one light-emitting diode (LED), for example at least one LED light chain.

In the extractor hood, the front surface may be designed to extract the haze. Alternatively or in addition to the extraction of the front surface of the hood of the extractor hood can be assigned at least one Wandabsaugung. This wall extraction may alternatively or additionally to the arranged at the lower end of the front surface of the hood lighting, preferably on the hood facing away from the hood extractor, at least one light source. For optimum alignment of the light, the lighting means is preferably arranged in a region of the wall suction which is cut off or bevelled with respect to the wall.

For operating the extractor hood and / or the cooking area and / or at least one further electrical device, the extractor hood, preferably in the area of the upper end or on the vertical portion of the quarter-circular front surface have at least one operating element. The control is advantageously designed as a control element with touch input, so-called touch control. Compared to a conventional button or button operation, a touch control is easier to clean.

Advantageously, the front surface of the extractor hood has at least one suction opening for the entry of sucked by the negative pressure haze in the

Suction chamber of the hood on. This suction opening can be distributed substantially over the entire surface of the front surface. For this purpose, the front surface may, for example, be designed essentially as at least one perforated plate. The arrangement of the suction openings over the entire front surface or visible surface has the advantage that the extractor hood has a large suction / suction surface. The

Flow rate of the aspirated vapor can be kept relatively low in this way, so that flow noise of the hood can be effectively avoided.

For cleaning the front surface or for changing at least one arranged in the housing vapor filter, for example at least one grease filter and / or at least one odor filter, the front surface is advantageously releasably connectable to the radial surfaces, in particular removed from the housing. For example, the housing may have at least one frame element, for example at least one side surface connecting the radial surfaces, into or into which the front surface can be inserted. Thus, the front surface may be formed as at least one by means of the frame member with the radial surfaces releasably connectable perforated sheet cassette. In order for the front surface or visible surface to be mounted more easily in the housing, in particular easier to insert and remove, the front surface can advantageously be essentially formed from at least two front surface elements. These front surface elements can for example be arranged side by side in the housing. For easier cleaning, the front surface elements are preferably dimensioned and selected from such a material that they can be cleaned in a standard dishwasher. For this purpose, the front surface elements in particular a maximum length of about 55 centimeters (cm) and a maximum width of about 45 cm.

According to an advantageous embodiment of the present invention, the extractor hood is designed for optional operation in the exhaust air or recirculation mode. For example, the hood can switch between exhaust and recirculation mode depending on the outside temperature.

For working in the exhaust air operation of the suction chamber is connected via the second radial surface with at least one exhaust chimney for discharging the sucked vapor. For this purpose, the advantageously arranged horizontally or in the direction of solder second radial surface at least one passage opening or connection opening to the exhaust chimney.

For working in recirculation mode, the exhaust chimney and / or the extractor hood can have at least one outlet opening, arranged for example laterally on the exhaust chimney and / or on at least one side surface of the extractor hood, for exiting mist filtered by means of at least one filter arranged in the housing.

The present invention further relates to at least one filter, in particular at least one grease filter and / or at least one odor filter, for use in an extractor hood according to the type set forth above.

Finally, the present invention relates to the use of at least one extractor hood according to the type set forth above and / or at least one Filters according to the above-mentioned kind for filtering haze occurring in a kitchen, in particular cooking hobs.

The same or similar embodiments, elements or features are provided with identical reference numerals in FIGS. 1A to 4B.

Best way to carry out the invention

To avoid superfluous repetitions, the following explanations with respect to the embodiments, features and advantages of the present invention (unless stated otherwise) relate both to the extractor hood 100 shown in FIGS. 1A and 1B and to the extractor hood 100 'shown in FIG. 2 as well on the extractor hood 100 "shown in Figure 3.

In the illustrated with reference to Figures 1A and 1B first embodiment of the present invention, a cooker hood 100, namely a head-free Wandesse in quadrant optics, shown.

This extractor hood 100 has a housing which surrounds at least one suction chamber of the extractor hood. In the housing, at least one fan 82 (see Fig. 4A, 4B), for example, at least one powerful blower, arranged to generate negative pressure in the suction chamber.

Furthermore, the housing, in particular on its front surface or suction surface 30, has suction openings or suction openings 90 for the entry of suction sucked in by the vacuum into the suction space of the extractor hood 100.

The central part of the front surface 30 has three front surface elements 33, 34, 35, namely three cassettes, which are removable for cleaning at least one arranged in the housing filter for filtering the sucked vapor. Due to their compact size, these cassettes 33, 34, 35 fit well into a dishwasher for your cleaning. The suction openings 90 are formed in the first embodiment shown in Figures 1A and 1B, characterized in that the front surface elements 33, 34, 35 with Distance in the housing of the hood 100 are arranged. When in the

1A and 1B, the front surface 30 essentially consists of three cassettes 33, 34, 35 made of colored glass.

In the second 100 'and third 100 "shown in FIGS. 2 and 3

Embodiment of the hood, however, the front surface 30 is substantially formed of three perforated metal cassettes 33, 34, 35. In this case, the suction openings 90 are distributed over the entire surface of the perforated sheet metal cassettes 33, 34, 35, which is shown schematically in FIGS. 2 and 3 as a broken grid.

The housing of the extractor hood 100, 100 ', 100 "has a quarter-circle-shaped profile, so that the counter 100, 100', 100" represents a quarter circle in the side view (compare FIGS. 4A, 4B). This shape is the most compact envelope of the given one Fan element 82.

In particular, the housing has three longitudinal surfaces 10, 20, 30, namely a first radially extending from a circle center M of the quarter-circle profile substantially straight radial surfaces 10, a second from the circle center M substantially straight and arranged substantially perpendicular to the first radial surface 10

Radial surfaces 20 and the quarter-circularly rounded front surface or visible surface 30. This convexly rounded front surface 30 connects a remote from the circle center M end 12 of the first radial surfaces 10 with an end remote from the circle center M end 22 of the second radial surface 20th

The front surface 30 has, for example, a length L of about ninety centimeters. This is particularly advantageous because the poppet 100, 100 ', 100 "thus has a large suction area, and the pest 100, 100', 100" can thus accommodate a relatively large filter volume for filtering the aspirated vapor, and yet is compact built. In particular, the icing 100, 100 ', 100 "can effectively extract the haze in this manner and still allow the user of a cooking area located under the butt 100, 100', 100" maximum headroom. In order to achieve a particularly good extraction of the mist, the pest 100, 100 ', 100 "can have a wall suction 70 cooperating with the suction chamber of the extractor hood 100, 100', 100" (see FIG. Advantageously, this Wandabsaugung 70 at least two removable front elements 72, 74, 76, for example, three juxtaposed filter cartridges. For the easier

Cleaning, these filter cartridges 72, 74, 76 can be dimensioned so that they can be rinsed in a standard dishwasher. Alternatively and / or in addition to the arranged in the housing of the hood filter, the Wandabsaugung 70 may have at least one filter, for example, at least one odor and / or fat filter, for filtering the aspirated vapor.

A frame element 36, 37 with a width B of, for example, approximately twenty-five millimeters (mm) is located laterally on the front side or front side 30 of the tray 100, 100 ', 100 ". The dimension of the width B of the frame element 36, 37 advantageously increases Furthermore, the wall suction 70 may also be surrounded by a frame formed corresponding to the frame element 36, 37 of the butt 100, 100 ', 100 "(see Fig. 3). This gives the Esse 100 100 ', 100 "a particularly elegant appearance.

At the lower edge of the food base body, in particular in the region of the lower end 31 of the front surface 30, is located in the illustrated in Fig. 1A and 1B first embodiment of the icing 100 and in the illustrated in Fig. 2 the second embodiment of the icing 100 'is a light unit 40 for Illumination of the worktop or the hob. The lighting means 40 can be designed differently, for example as a light bulb, as a halogen lamp, as a fluorescent tube or as an LED light chain.

As shown in FIG. 3, however, the lighting means can also be arranged on the wall suction 70, in particular on a bent region of the wall suction 70 facing the cooking area.

At the upper, the second radial surface 20 facing the end 32 of the front surface 30, in particular at the upper edge 32 of the central filter element 34, there is a Operating unit 50. This operating unit 50 is advantageously designed as a touch operation, since it is easy to clean.

An exhaust air chimney 60 can be located on the main body or housing of the butt 100 (cf., for example, FIG. 4A), which optionally has suitable openings 62 (see, for example, FIG. 2) for discharging the exhaust air during recirculation operation on its sides. These openings are advantageously arranged at a distance from the extractor hood 100, 100 ', 100 "or near the ceiling, since thus the user of the hood 100, 100', 100" as little as possible by Ausblasgeräusche and / or the blown air stream or the blown filtered Haze is impaired.

Alternatively, the exhaust air can also be conveyed through a wall bore into an exhaust duct arranged in the wall 200 or directly to the outside (see FIG. 4B). The extractor hood according to the invention can be designed for pure exhaust air operation, for pure recirculation mode or for combined or demand-controlled, for example, temperature-controlled, exhaust / recirculation mode.

The extractor hood 100, 100 ', 100 "shown in FIGS. 1A to 4B differs from extractor hoods known from the prior art in particular in that the housing has a Vi-circular profile in side view, the fan 82 being arranged inside the Vi-circular profile is (see Figures 4A and 4B).
