The at least one filter unit (3) can be slid downwards in relation to the extractor housing (2) beyond the underside of the extractor housing (2).

Description

The invention relates to an extractor hood, in particular for sucking and filtering the vapors produced during cooking.

The suction and filtering of the resulting vapors during cooking is now possible in a variety of ways. One known type is the so-called down-draft or table extractor devices. In these down-draft extractors, the extractor and filter unit is located behind the hob or cooktop. The filter unit is located in the rest position of the down-draft extractor device below the work surface, so that the inflow surface of the filter unit is not visible to the user. By vertically moving the filter unit of the down-draft extractor device from the work surface up, the filter surface is exposed and the vapor can be sucked and filtered. During aspiration of the vapor, the suction unit remains below the work surface.

A disadvantage of these extractor devices is that for sucking off the Wrasens due to the positioning of the suction unit, a deflection of the flow direction of Wrasens must be done by 180 ° down. A further disadvantage is that a high suction power is required to implement this deflection in down-draft extractor devices. This usually requires a large dimensioning of the suction unit. In addition, it is not readily possible to retrofit existing hobs with such a fume extraction device.

The present invention is therefore based on the object to provide a cooker hood, in which the required deflection of the flow direction of the Wrasens for sucking and filtering the Wrasens is minimized. In addition, the space required for the hood to be minimized and the hood to hinder the user as little as possible in the cooking process.

The invention is based on the finding that this object can be achieved by providing an extractor hood, which is arranged above the cooking surface and whose filter unit is pulled out of the underside of the extractor hood only when required.

The object is achieved by an extractor hood according to independent claim 1. Further features and details of the invention will become apparent from the dependent claims, the description and the drawings.

According to the present invention, an extractor hood, in particular for sucking and filtering the vapors produced during cooking, is provided. The extractor hood has an extractor housing and at least one filter unit, which is arranged displaceably in relation to the extractor housing. The extractor hood according to the invention is characterized in that the at least one filter unit with respect to the extractor housing downwards over the underside of the extractor housing is also a drawer-like displaced.

Directional information, such as top, bottom, front and back, as well as designations such as bottom, top, front and back, are hereinafter understood to refer to an extractor hood and its components in the assembled state. The front of the hood and its components here is the side facing the user of the hood and facing away from the back. The back is the side facing a room wall where the cooker hood is mounted and which is also called a mounting wall.

In the extractor hood, which can also be referred to as vapor withdrawal, it is a device for suction and preferably for filtering the resulting vapors during cooking. The vapor describes the air in which, for example, water and / or fat particles are contained. The extractor hood consists of a fume hood and a filter unit. In the extractor housing, the suction unit or suction means for generating a negative pressure in the extractor housing and thus be arranged to suck the Wrasens. The suction unit represents, in particular, the fan or the fan of the extractor hood. At least one filter element is arranged in the filter unit. On the filter unit an inflow surface or suction opening is formed, which is covered by at least a part of the at least one filter element. The inflow surface is preferably provided on one of the surfaces of the filter unit, on which the dimensions of the filter unit are greatest. In a vertically oriented filter unit, the inflow surface is preferably located at the front of the filter unit.

According to the invention, the filter unit is arranged displaceably in relation to the extractor housing, that is to say the filter unit can be displaced relative to the extractor housing. According to the present invention, relative movement of the filter unit to the extractor housing is understood to mean both movement by movement of the filter unit and displacement by movement of the extractor housing. The relative displacement of the two components to each other is preferably purely translatory, that is, it is a linear displacement. In such a translational displacement, the filter unit or the extractor housing in the two possible directions, in particular up and down, be moved. For this shift, the filter unit and the extractor housing are connected together in a suitable form. The suitable shape can be realized for example by a guide device which can be arranged on the filter unit or on the extractor housing. The guide device may comprise, for example, a guide rail.

Preferably, the extractor housing of the hood is attached to the mounting wall. The mounting wall is aligned vertically. When the cooker hood is attached to the mounting wall via the extractor housing, the filter unit can be displaced relative to the extractor housing. If, on the other hand, the extractor hood is fastened to a mounting wall via the filter unit, the extractor housing can be displaced with respect to the filter unit.

By moving the filter unit relative to the extractor housing, two relative positions between the filter unit and the extractor housing can be adjusted.

The first relative position is preferably the position at which the filter unit is preferably completely received in or covered by the extractor housing. Here, the top of the filter unit can be flush with the top of the extractor housing. This first relative position, which represents an extreme position, is also referred to below as the rest position or as the closed position. In the rest position preferably the entire inflow surface of the filter unit is not visible to the user, but is covered by the extractor housing.

The second relative position is a position in which the filter unit protrudes at least partially over the underside of the extractor housing. In an extreme position, which is also referred to as the end position, the majority of the filter unit is outside the extractor housing. In this case, preferably, the entire inflow surface of the filter unit is outside of the extractor housing and can be flowed by vapors. The second relative position is also referred to below as the operating position or open position. Several operating positions can be set, wherein at each of the operating positions, at least part of the filter unit protrudes beyond the underside of the extractor housing and, in particular, a portion of the inflow area can be flowed by vapor.

The changeover from the operating position of the extractor hood to the rest position of the extractor hood is achieved by a change of position of the filter unit, which is referred to as "insertion", in which the filter unit is moved upwards. The changeover from the rest position of the extractor hood into the operating position of the extractor hood is achieved by a change of position of the filter unit, which is referred to as "pulling out", in which the filter unit is moved downwards.

According to the invention, the filter unit is displaceable downwards beyond the underside of the extractor housing with respect to the extractor housing. The operating position of the hood is therefore adjusted by drawer-like moving the filter unit with respect to the extractor housing down over the bottom of the extractor housing. Since the filter unit extends in the operating position of the hood downward over the extractor housing, the hood according to the invention can be mounted above the hob.

Drawer-like in the sense of the present invention is understood to mean that the filter unit is displaced in its longitudinal direction, wherein the length of the filter unit designates the distance between the upper side and the lower side of the filter unit.

Due to the inventive design of the hood with a mounting of the hood above the hob, the filter unit in the operating position of the hood closer to the hotplate, so led to the origin of Wrasens. In addition, by the movement of the filter unit in the direction of the underside of the extractor housing, the depth of the hood is slightly lower than is the case with the extractor hood, in which the filter unit is pulled forward from the extractor housing. These extractor hoods, in which the filter unit is pulled out to the front, are also referred to as Flachschirmhauben. In the extractor hood according to the invention, however, the hood can be attached to the mounting wall at a lower level than is possible with known flat-screen hoods without hindering the user. As a result of this closer arrangement of the extractor hood and in particular of the filter unit pulled out of the extractor housing in the operating state, the distance which the vapor must travel to the extractor hood and in particular the filter unit is lower and the vapor can thus be faster be sucked off. As a result, the cooking surface can be better protected against contamination. In addition, in the extractor hood in the rest position, a smaller space requirement, since the filter unit is preferably completely accommodated in the extractor housing. In addition, no adjustment of the hotplate is required by the arrangement of the hood above the hob in contrast to the known down-draft extractor devices.

Since in the extractor hood according to the invention, both the filter unit and the extractor housing with the suction unit above the cooking zone, the vapor to reach the suction unit does not have to be deflected by 180 °, as in a down-draft extractor device down. Rather, the vapor must be deflected only slightly from the main flow direction, which usually runs vertically upwards, so that the required suction unit can be made smaller. In addition, a hotplate can be retrofitted with the extractor hood according to the invention, without a modification of the hotplate is required.

According to one embodiment, the filter unit is displaceable in the vertical direction with respect to the extractor housing.

In this embodiment, therefore, the filter unit is arranged vertically in the extractor hood, which means that the longitudinal direction of the filter unit lies in the vertical direction. In this vertical embodiment of the filter unit, there is a right angle between the surface of the filter unit and the surface of the hob. Since an inflow surface is formed on the filter unit, preferably on its front side, through which vapors can enter the extractor hood, in this embodiment the vapor only has to be deflected by 90 ° from a vertical main flow direction in order to enter the vertically aligned inflow opening. Subsequently, the vapor or the purified air can be deflected by a further deflection by 90 ° back up into the vertical. It is thus in this embodiment, only an offset of the main flow direction of the vapors and not as in the prior art deflecting by 180 ° down required.

If the hood is attached to a vertical mounting wall, so the filter unit can be moved beyond the bottom of the extractor housing in the vertical direction, ie parallel to the mounting wall, down. In this embodiment, it is advantageous that the distance between the front of the hood and the mounting wall can be minimal, since in the depth of the hood only the thickness of the vertically oriented filter unit is located.

In another embodiment, the filter unit is displaceable relative to the extractor housing in a direction that is inclined at an angle to the vertical.

In this embodiment, therefore, the filter unit is arranged in the extractor hood at an angle to the vertical, which means that the longitudinal direction of the filter unit is at an angle to the vertical.

The angle of inclination of the displacement direction and thus also of the filter unit is the smallest angle which is defined between the vertical and the direction of displacement of the filter unit. The angle of inclination may be described by the vertical distances of the mounting wall to the lower end of the back of the filter unit and the mounting wall to the upper end of the back of the filter unit. The vertical distance of the mounting wall to the lower end of the back of the filter unit in this embodiment is less than the distance of the mounting wall to the upper end of the back of the filter unit. This means that the filter unit is arranged from the mounting wall inclined upwards and forwards in the extractor hood.

In the inclined arrangement of the filter unit, a leading surface of the filter unit formed in the front of the filter unit is not parallel to the main flow direction of the Wrasens, which is usually in the vertical. As a result, a better flow of the inflow surface of the filter unit can thus be created, in which the filter element is provided. In addition, at the same time the inflow surface of the filter unit can be increased at a constant height of the hood, since the occupied by an inclined filter unit height is lower than that of a vertically oriented filter unit. Thus, the amount by which the filter unit can be pulled out of the hood can be increased. This is a larger surface of the filter unit, which can cover the hotplate.

Preferably, the angle of inclination of the displacement direction of the filter unit and thus of the filter unit itself to the vertical is greater than 0 ° and less than 90 ° and preferably greater than 0 ° and less than 20 °.

With an inclination angle of the displacement direction and thus the orientation of the filter unit of 0 °, the filter unit is arranged parallel to the vertical mounting wall, which allows a very space-saving design and arrangement of the hood.

Even with an inclination of the filter unit to the vertical, the distance between the front of the hood and the mounting wall should be as low as possible in order to minimize the spatial impairment of the user. By restricting the inclination angle to 20 °, on the one hand, the area of the cooking area covered by the filter unit can be increased and, in addition, a better angle of incidence of the filter unit can be made possible. Nevertheless, even with this angle of inclination, the extractor hood does not protrude so far into the space above the cooking point that the impairment of the user would be considerable.

In a further embodiment, the filter unit is arranged on the rear side of the extractor housing.

In this embodiment, the extractor housing is arranged in front of the filter unit from the direction of view of the user of the extractor hood.

The arrangement of the filter unit at the rear of the extractor housing, the extractor housing can be constructed simpler, since only on the back of the extractor housing guides, such as guide rails must be provided for drawer-like guiding the filter unit. Furthermore, it is advantageous in this arrangement that the filter unit is arranged concealed by the arrangement on the back of the extractor housing for the user in the rest position, so that the filter unit and in particular the filter element for the user is not visible.

The extractor housing, in this embodiment, for example, have a cuboid shape whose height is greater than the depth. The width of the extractor housing corresponds at least to the width of the filter unit.

In a further embodiment, the filter unit is arranged between a front extractor housing part and a rear extractor housing part.

In contrast to the arrangement of the filter unit at the rear of the extractor housing, the extractor housing is in this embodiment in a two-part form. This two-part form is characterized by a front and. realized a rear extractor housing part.

The front extractor housing part is directed to the user of the hood. The rear extractor housing part is arranged so that it preferably rests against the mounting wall.

In this embodiment, the various extractor housing parts can accommodate or form different components of the extractor hood. For example, the front extractor housing part can accommodate the essential components for operating the extractor hood, such as the fan. If the essential components for operating the hood in one of the two extractor housing parts, for example, in the front extractor housing part are arranged, the other extractor housing part, for example, the rear extractor housing part can be very easily formed, for example in the form of a pure cover. Also, a reverse construction, in which, for example, the fan is accommodated in the rear extractor housing part and the front extractor housing part is only a cover, according to the invention is possible.

Preferably, the embodiment of the hood with a two-part construction of the extractor housing can be applied to cooker hoods having a tilted to the vertical filter unit. Namely, in this embodiment, a back cover of the filter unit can be realized, so that the rear side of the filter unit, which is at a distance from the mounting wall at an inclined filter unit at the top, is covered.

In a further embodiment, the length of the filter unit is less than or equal to the height of the extractor housing.

For the purposes of the invention, the length of the filter unit is understood to mean the distance between the bottom side and the top side of the filter unit in the area of the filter unit. The length of the filter unit is thus the area dimension of the filter unit which lies parallel to the direction of displacement of the filter unit. As the height of the extractor housing is understood in the context of the invention, the distance between the bottom and the top of the extractor housing. The height of the extractor housing and the length of the filter unit preferably have the same spatial orientation.

By the embodiment in which the length of the filter unit is less than or equal to the height of the extractor housing, the filter unit can be completely covered by the extractor housing in the rest position or is included in this and is not visible to the user. Only in the operating position of the hood, the filter unit is beyond the bottom of the extractor housing.

In a further embodiment, the filter unit has a passage opening and the Fume hood housing an inlet opening, wherein at least, in an operating position of the filter unit, the passage opening and the inlet opening at least partially overlap.

The passage opening and the inlet opening are each provided on the sides of the filter unit and the extractor housing, which face each other. Preferably, therefore, the passage opening at the front of the filter unit and the inlet opening at the rear of the extractor housing or in a two-part extractor housing at the rear of the front extractor housing part are provided. On the extractor housing, the inlet opening is in the lower region of the extractor housing and on the filter unit, the passage opening is provided in the upper region of the filter unit.

For receiving and filtering the Wrasens, the filter unit has an inflow, through which the vapor can enter into the filter unit. At or in this inflow surface at least a part of the filter element of the filter unit is arranged. After filtering the vapor, the vapor exits the filter unit through the passage opening and is drawn into the extractor housing via the inlet opening of the extractor housing.

For the passage of Wrasens of the filter unit in the extractor housing overlap the openings in the two components in at least one of the operating positions at least partially. In one of the operating positions, which represents the extreme position, the two openings of the two components of the extractor hood preferably completely overlap. This overlap maximizes the area over which the vapor from the filter unit can enter the extractor housing.

Preferably, the passage opening of the filter unit and the inlet opening of the extractor housing have the same size. In addition, the filter unit may have a plurality of passage openings and the extractor housing may have a plurality of inlet openings.

By the drawer-like displacement of the filter unit with respect to the extractor housing, the degree of overlap between the passage opening and the inlet opening can be varied, so that a targeted flow of air or the Wrasens can be adjusted.

In order to prevent the escape of vapor at the transition from the filter unit to the extractor housing, a seal, in particular a sealing lip, may be provided at one of the openings.

In a further embodiment, the suction power of the extractor hood is regulated by the drawer-like displacement of the at least one filter unit to the extractor hood.

For example, the suction power of the hood can be regulated by the displacement of the filter unit so that with a maximum extraction of the filter unit from the extractor housing, the full suction of the hood is available. In a situation in which the filter unit is pulled out of the extractor housing only to a small extent, a lower suction power of the extractor hood can be set. The adjustment of the suction power can be realized by contacts on the filter unit or the extractor housing. The regulation of the suction power can be infinitely or in stages. In addition, the cover of the openings provided in the components is adjusted by moving the filter unit to the extractor housing. In all operating positions, the design of the components of the extractor hood ensures that a passage opening of the filter unit and an inlet opening of the extractor hood cover at least in some areas.

Furthermore, it can also be provided that the activation of the extractor hood takes place by pulling the filter unit out of the rest position. Likewise, the shutdown of the hood can be done by inserting the filter unit to the rest position. The switching on and off of the hood can be realized for example by a magnetic switch, which can be provided on the guide unit for moving the filter unit, on the filter unit or the extractor housing. By such an implementation, for example, controls, in the form of control buttons or controls on the outside of the hood, which must be operated by the user, can be saved.

The displacement of the filter unit can be done manually, hydraulically or electrically, in particular by a motor drive.

In a further embodiment, the at least one filter unit comprises at least one filter element and a filter housing, and the at least one filter element is arranged in the filter housing.

The filter element comprises the actual filter, which as an expanded metal filter, for example as a stainless steel filter may be formed, by means of which the vapor is cleaned of dirt. The filter element, which may represent a filter cartridge, for example, is arranged in the filter housing, wherein the filter housing may be formed in different ways. The filter element is arranged in the filter housing such that it covers an inflow area, which can also be referred to as an intake opening and is provided in the filter housing. Behind the filter element, there is preferably an intake space leading to the passage opening in the filter unit. In addition to the suction opening and the passage opening, which are preferably provided on the same side of the filter unit, the filter housing is closed. In particular, the filter housing on the side, which is directed to the mounting wall, closed and can protect the mounting wall from contamination.

The invention will be explained again below with reference to the accompanying drawings. Hereby show:

Identical components are provided in the figures with the same reference numerals and their structure and function will optionally be explained only once.

In 1a is a schematic perspective view of a first embodiment of the extractor hood according to the invention 1 in the resting position and in 1b shown in an operating position.

The extractor hood 1 includes a cooker hood 2 and a filter unit 3 , The filter unit 3 is behind the extractor housing 2 arranged. In the illustrated embodiment, the width of the filter unit corresponds 3 the width of the extractor housing 2 and the length of the filter unit 3 corresponds to the height of the extractor housing 2 , The filter unit 3 is like a drawer to the extractor housing 2 arranged and can over the bottom of the extractor housing 2 pulled down and pushed up behind this.

In the resting position, the in 1a is shown is the filter unit 3 completely from the extractor housing 2 covered. In the in 1b shown operating position is the filter unit 3 maximum from the extractor housing 2 pulled out.

At the in 1 illustrated embodiment of the hood 1 it is an extractor hood 1 which can be fixed to the mounting wall parallel to a vertical mounting wall (not shown). In this embodiment of the hood 1 the displacement of the filter unit runs 3 in relation to the extractor housing 2 parallel to the mounting wall, the filter unit 3 at the back of the extractor housing 2 is arranged. The filter unit 3 is thus moved along the mounting wall. Due to this embodiment of the extractor hood 1 is the volume of construction of the extractor hood 1 low as the depth of the hood 1 also in the operating state only by the depth of the extractor housing 2 and the thickness of the filter unit 3 is formed. Thus, the deterioration of the user is low.

In 2 is a schematic perspective view of the hood 1 of the first embodiment shown in the rest position. The extractor housing 2 This is shown transparently to give an insight into the interior of the cooker hood 1 to grant. In the illustrated rest position is the filter unit 3 completely behind the extractor housing 2 pushed. In 2 are a passage opening D of the filter unit 3 , which in the filter housing 30 is introduced, shown. Furthermore, the extractor housing 2 an inlet opening E on. The passage opening D is in the upper region of the front of the filter unit 3 introduced, which is above the inflow area A. The inlet opening E, however, is in the lower region of the rear of the extractor housing 2 brought in. The two openings represent slots that extend in the width direction. In the rest position shown, the passage opening D and the inlet opening E do not overlap.

At the in 2 shown extractor hood 1 corresponds to the length L of the filter unit 3 the height H of the extractor housing 2 , This means that in the rest position the filter unit 3 completely from the extractor housing 2 is covered.

In the filter unit 3 is only the filter element 31 (in 2 not shown) in the filter housing 30 arranged.

In 3 is a schematic side view of the hood 1 of the first embodiment shown in an operating position.

The extractor hood 1 is arranged above a cooking point K on a mounting wall (not shown). On the hob K is a cooking vessel in the form of a pot 50 arranged from the vapors 4 rises.

The extractor hood 1 consists of the extractor housing 2 and the filter unit 3 and is in an operating position. In this operating position is the filter unit 3 , which at the back of the extractor housing 2 is arranged, relative to the extractor housing 2 shifted so far down in the direction of the cooking point K, that the passage opening D of the filter unit 3 and the inlet opening E of the extractor housing 2 completely cover up.

The rising vapor 4 is through a in the extractor housing 2 sucked generated negative pressure and flows the inflow surface A of the filter unit 3 at. The Wrasen 4 flows through the filter unit 3 and passes through the passage opening D and the inlet opening E in the extractor housing 2 the extractor hood 1 ,

Also in the operating position is a part of the filter unit 3 behind the extractor housing 2 , In this area, in which the two parts bear against each other, the passage opening D and the inlet opening E are provided.

By the arrangement of the extractor hood 1 above the hob K can the hood 1 be positioned close to the hob K, so that the vapors 4 immediately after leaving the pot 50 can be sucked off.

In addition, the Wrasen must 4 no deflection down. In addition, by shifting the filter unit 3 relative to the extractor housing 2 when covering the passage opening D and the inlet opening E, the suction power of the extractor hood 1 be regulated.

In 4 is a schematic perspective view of the hood 1 of the first embodiment shown in an operating position. As in 4 represented, Wrasen rises 4 from a pot 50 from a cooking place K (in 4 not shown) on and off the cooker hood 1 sucked. In the illustrated operating position, the inflow area A of the filter unit 3 on the user of the hood 1 directed. In the inflow area A of the filter unit 3 is located in the filter housing 30 the filter element 31 to clean the Wrasens 4 , As already with respect to the 3 described overlap in an operating position, the passage opening D of the filter unit 3 and the inlet opening E of the extractor housing 2 the extractor hood 1 ,

This in 4 shown extractor housing 2 includes the fan (not shown) for exhausting the vapor, so that the filter unit 3 can be designed as a flat component.

In 5 is a schematic perspective view of an extractor hood 1 represented in a second embodiment in the rest position.

In this embodiment of the hood 1 there is the extractor housing 2 from a front extractor housing part 20 and a rear extractor housing part 21 , The filter unit 3 is between the front extractor housing part 20 and the rear extractor housing part 21 arranged. Furthermore, the extractor hood 1 fixed at an angle α with respect to the vertical on a mounting wall (not shown). For attachment to the mounting wall is at the rear extractor housing part 21 the extractor hood 1 a wall mount 40 intended. In the inclined arrangement of the hood 1 is the distance from the bottom of the hood 1 to the mounting wall less than the distance of the top of the hood 1 to the mounting wall. Also the filter unit 3 in this embodiment is located at the angle α with respect to the vertical.

At the in 5 shown extractor hood 1 is the front extractor housing part 20 designed as a cover and the fan to suck the Wrasens 4 is in the rear extractor housing part 21 intended. In addition, the in 5 shown extractor hood 1 a lock V on. By this lock V, the filter unit 3 kept in the resting position.

In 6 is a schematic perspective view of an extractor hood of the second embodiment shown in an operating position. In this operating position is the filter unit 3 so far from the extractor housing 2 pulled out that the inflow surface A is exposed, so that the vapors 4 can be sucked off. The lock V is released in this operating position.

Due to the inclined mounting of the extractor hood 1 on a mounting wall and the inclined orientation of the filter unit 3 , is also the inflow area A in the front of the filter unit 3 inclined.

In the two illustrated embodiments of the hoods 1 The fan can be smaller, because of the vapor 4 in contrast to known down-draft cooker hoods only slightly laterally must be deflected. Due to this smaller dimensioning of the fan can significantly reduce the volume of the cooker hood 1 be achieved.

With the present invention, a movable filter surface can be realized in skew and flat wall meals. Since the filter surface is generally open, it is visible to the user. By cooking, the cooker hood can also pollute if the cooker hood is not needed. By the inventive movable arrangement of the filter unit, the filter unit can be inserted when not in use in the hood and pulled out of this if necessary.

By such a construction of the hood, the suction surface of the filter element, which is also referred to as a grease filter, be brought closer to the cooking surface. Thus, the way the vapor must travel to the grease filter is reduced, so that the vapor can be sucked out more effectively. If the cooker hood is not used, the filter unit can be pushed into the cooker hood, hiding the dirty filter. Thus, the main dirt surface is no longer visible to the user. In addition, the baffle behind the hob is protected against dirt when the filter is pulled out.
