Abstract

The fume extraction hood has a mounting (7) for the grease filter and/or vapor guide plate (2) allowing a limited swing movement of it in relation to the hood housing (3). The mounting is at the lower end of the swing movement. A lock (8), away from the mounting, holds the filter in place in the closed position.

Description

The invention relates to an extractor hood having a housing having a suction opening and at least one surface element arranged in the suction opening, in particular a grease filter and / or a Wrasenleitblech, wherein at least one bearing point is provided for the surface element in which the surface element at least in the vertical direction relative to Housing is set.

Cooker hoods are used in kitchens in the home to capture the fumes produced at a cooking place and either filtered back into the room air or remove it from the room to the outside. As extractor hoods in the context of the present invention, both such hoods are referred to, which are mounted on or in a wall unit of a kitchen cabinet, as well as food, which are fixed independently of the kitchen furniture on a wall or on the ceiling.

Extractor hoods have a housing in which inter alia, a fan is arranged, with which the vapor is sucked through a suction port. In the suction opening is a grease filter and / or a Wrasenleitblech, collectively referred to as surface element. The task of the grease filter is to remove as completely as possible the fat components contained in the vapor. The size of the grease filter corresponds to the size of the intake, so that all sucked-in steam flows through the grease filter. A Wrasenleitblech is used in an extractor hood with Randabsaugung. Here, the Wrasenleitblech is slightly smaller than the suction port of the housing, so that between the housing and Wrasenleitblech a gap is present, through which the vapor is sucked. As a rule, a grease filter is arranged behind the Wrasenleitblech. It is also known to combine a Wrasenleitblech with a grease filter to a common area unit. The Wrasenleitblech and the grease filter thereby form a structural unit and are mounted together on the housing or dismantled again.

In order to facilitate cleaning of the surface element, and to allow access into the interior of the housing, the surface element is releasably attached to the Housing attached. For this purpose, a bearing point is provided which fixes the surface element relative to the housing at least in the vertical direction. Usually, the bearing allows pivotal movement of the surface element relative to the housing. The bearing can for this purpose include, for example, a hook or a hinge. In addition to the bearing usually a locking element is provided, with which the surface element can be locked to the housing. The locking element is spaced from a pivot axis of the surface element defined by the bearing point. To remove the surface element, the locking element is first released, then the surface element is pivoted about the pivot axis formed in the bearing point down and finally solved the surface element at the bearing point of the housing.

In prior art cooker hoods, damage to the panel, a cooktop located under the hood, or a portion of the wall between the cooktop and the extractor fan may occur because the panel is released after release of the latch and the panel then falls down either or swinging to the back and striking the wall of the room.

Known devices that have been proposed to solve this problem, for example, in the publications DE102004006121A1 . DE10208475A1 or DE102004043069A1 described. However, they do not completely solve the described problem, are uncomfortable to handle or are not suitable for particularly heavy surface elements. The present invention is therefore an object of the invention to provide an extractor available in the damage due to an uncontrolled movement of the filter are reliably avoided.

This object is achieved in that the bearing allows a limited pivotal movement of the surface element relative to the housing down. Starting from the operating position of the surface element, the surface element can be pivoted about an axis formed by the bearing point down. This pivoting movement is limited by the bearing by this has a corresponding structural design. An uncontrolled downward panning of the Surface element due to which gravity is thus reliably prevented. On additional security elements that limit the pivot angle of the surface element can be dispensed with.

Here, the bearing defines a lower end position for the pivotal movement of the surface element. In the lower end position, the surface element is deflected by a few degrees, for example by 10 to 20 degrees, from the horizontal. Too wide pivoting of the surface element and thus striking the surface element to the wall below the hoods is reliably prevented.

An advantageous development of the invention provides that when surface element located in the lower end position, the surface element is fixed by means of the bearing on the housing. This means that when the surface element is in its lower end position, the surface element can not fall down. Instead, the bearing secures the surface element to the housing. A manual removal of the surface element is possible when the surface element is pivoted upwards from its end position.

The surface element has an operating position in which the surface element can be fixed by means of a locking element acting between the surface element and the housing. In its operating position, the surface element is held by means of the locking element. The locking element prevents downward pivoting of the surface element due to its gravity. The locking element, as well as the bearing, carries a part of the weight of the surface element. To disassemble the surface element, the operator first releases the locking element and then pivots the surface element slightly downwards.

Preferably, the locking element is arranged at a distance from the bearing point. This allows a uniform distribution of the weight of the surface element on the locking element and on the bearing. The locking element does not have to be suitable for receiving a torque.

According to an expedient embodiment, the locking element is designed as a push-push element. As a push-push element such locking elements are referred to, which are locked at a first press in a certain direction and are released in a same press again. In the case of the surface element, this means that the surface element is pressed to lock the locking element in the direction of the housing. A renewed pressing of the surface element in the direction of the housing unlocks the locking element, so that the surface element is pivotable downwards.

The surface element has at least one removal position in which the surface element from the bearing is detachable. The removal position is defined by a certain angular position of the surface element, in which the bearing allows removal of the surface element. Outside the removal position, either the bearing or the housing block the surface element, so that this can not be removed from the hood.

The surface element is in the removal position in a pivoting position between the operating position and the end position. In the operating position, the housing of the extractor hood prevents removal of the surface element, while in the end position, the bearing point fixes the surface element.

According to a possible embodiment of the invention, the bearing comprises a guide rail and guided in the guide rail guide element. The guide rail may for example have a U-shaped profile.

The guide rail extends parallel to the surface element, when this is in the operating position. The guide element is attached to the surface element and is inserted in befindlichem in operating position surface element in the guide rail.

Preferably, the guide rail is attached to the housing and the guide element is attached to the surface element. However, it is also possible a reverse arrangement.

The guide rail and the guide element are displaceable relative to each other in the longitudinal direction of the guide rail. When the surface element is mounted in the operating position, the guide rail defines the position of the surface element in the direction perpendicular to the surface element, as well as in the direction parallel to the surface element and perpendicular to the guide rail. In the direction parallel to the guide rail, the position of the surface element is defined exclusively by the locking element.

With particular advantage, the guide element is guided with play in the guide rail, such that a limited angular inclination of the guide element is made possible relative to the guide rail due to the game. This game of the guide element allows the pivotal movement of the surface element between the operating position and the lower end position.

Particularly advantageously, the guide rail on a locking cam, which prevents relative to the guide rail relative to the guide rail in dependence on the angular inclination of the guide element relative to the guide rail. The locking cam produces a positive and / or frictional connection between the guide rail and the guide element, specifically when the surface element is in its lower end position. Due to the angular offset between the guide element and the guide rail of the locking cam is pressed onto the guide rail. This leads to a locking of the guide element in the guide rail, which prevents the guide element from being pushed out of the guide rail. The surface element is thus secured and fixed.

The same advantage can be achieved if the guide element has a locking cam, which prevents relative to the guide rail, depending on the angular inclination of the guide element relative to the guide rail displacement of the guide element. In this constructive reversal of the detent principle described above, the detent cam is located on the guide element, which is pressed against the guide rail when the lower element is in the lower end position.

It is particularly advantageous if both the guide rail and the guide element each have a detent cam which, relative to the guide rail, prevents displacement of the guide element relative to the guide rail as a function of the angular inclination of the guide element. The two locking cams form a positive connection. The ability to remove the surface element in a direction parallel to the surface element from the bearing, is thereby reliably prevented.

Further advantages arise when the guide rail and / or the guide element are made of plastic. Plastic has a very favorable elasticity and stability behavior for the present application. In particular, it is favorable to manufacture the guide rail made of plastic and the guide element made of metal, for example aluminum.

Further advantages and details of the invention will be explained in more detail with reference to the embodiment shown in the schematic figures.

In FIG. 1 is shown in perspective view designed as an Eszah extractor hood 1. The extractor hood 1 comprises a housing 3, the underside of which has a large intake opening, in which two surface elements 2 are arranged. The surface elements 2 are formed in the present embodiment by a respective Wrasenleitblech, which is in each case combined with a arranged on the back of the Wrasenleitblechs grease filter. The vapor is sucked through openings at the edge of the Wrasenleitblechs and then flows through the grease filter.

Wrasenleitblech and grease filter form a structural unit, which is referred to here as surface element 2.

At the top of the housing 3, a chimney 4 is arranged, in which there are a fan and channels for draining the filtered vapor. Integrated into the housing are lighting elements 5 with which a cooker located below the hood can be illuminated. A generic extractor hood, in particular with a built-up of a Wrasenleitblech and a grease filter surface element 2 is in the published patent application DE 10 2008 020 149.9 described.

The present patent application relates to the type of attachment and storage of the surface elements 2 on the housing 3. Due to the high weight of the constructed of a Wrasenleitblech and a grease filter surface element are at its attachment and storage special requirements.

In FIG. 2 the housing 3 is shown with only one surface element. The second surface element is omitted in the figure, so that the interior of the housing is partially visible.

In the case of the surface element 2, the intake openings 6 circulating on the edge can be seen in the present illustration, through which the vapor rising from the cooking point is sucked. Behind the intake openings is a grease filter, with which the fat particles contained in the Wrasenstrom are deposited.

At the rear end of the housing 3 (left in the drawing) are three bearings 7 for the surface elements 2, wherein each surface element 2 is held with its two rear corners in each case a bearing 7. The front side of each surface element 2 is fastened to the housing 3 with a respective locking element 8. The locking elements 8 are designed as push-push elements. A release of the locking element 8 takes place in that the surface element 2 is pressed in the region of the locking element 8 upwards. Subsequently, the surface element 2 can be pivoted downwards, wherein the pivot axis of the surface element 2 is in the region of the bearing points 7 and is defined by this. In order to then lock the surface element 2 again, the surface element 2 is pressed in the region of the locking element 8 back up. When the surface element 2 is then released, the surface element 2 is locked in the housing 3.

In the picture according to FIG. 3 the locking element 8 is unlocked and the surface element 2 is pivoted down to an end position. According to the invention, the bearing 7 is designed such that it allows a pivoting movement of the surface element 2 about a pivot axis formed in the bearing 7. In addition, the bearing 7 defines an end position for the pivotal movement of the surface element 2 down. This prevents the panel from swinging down uncontrollably after it has been unlocked by an operator and then released. Further, the bearing 7 is formed such that the surface located in the end position element 2 is fixed to the housing 3, that a drop of the surface element 2, after it was released by the operator, is reliably prevented. In order to remove the surface element 2 from the bearing 7, it must rather be pivoted slightly upward by the operator again, before it can be removed substantially forward.

As essential components, each bearing 7 comprises a guide rail 9 and a guide element 10. In the present embodiment, the guide rails 9 are fixed to the housing 3, while the guide elements 10 are arranged on the surface elements 2.

FIG. 4 shows a guide rail 9, which is fixed with its rear end (left in the drawing) to the housing 3 of the hood 1. The guide rail 9 has an upper groove 11 and a lower groove 12. In the lower groove 12 can be fixed to the surface element 2 guide member 10 (see FIG. 5 ) are inserted. The upper groove 11 has no function in the illustrated mounting position of the guide rail 9. It is therefore provided because the guide rail 9 for supporting the second rear corner of the surface element 2 rotated by 180 degrees on the housing 3 can be attached. In this case, the groove 11, which then represents the lower groove, serves to receive the guide element 10, while the groove 12 is not used. Each of the grooves 11, 12 is associated with a cam 13 formed on the guide rail 9. The cam 13 serves to secure the surface element 2 against accidental slipping out of the guide rail. 9

FIG. 5 shows a section of a surface element 2 with an attached guide member 10. The guide member 10 is shaped so that it with its upper portion in the direction of the left in the drawing in the lower groove 12 of the guide rail 9 (see FIG. 4 ) can be inserted. On the upper side of the guide element 10 are two cams 14, which are also provided to prevent slipping out of the guide member 10 from the guide rail 9. Only the left in the drawing cam 14 is effective in the illustrated arrangement. The right in drawing cams 14, however, is effective when the guide member 10 is mounted at the other rear corner of the surface element 2 rotated by 180 degrees.

In the picture according to FIG. 6 is a bearing 7 with an end position downwardly pivoted surface element 2 shown. In the lower groove 12 of the housing 3 fixed to the guide rail 9, the guide member 10 is inserted. The guide element 10 is attached to a rear corner of the surface element 2. The surface element 2 is pivoted in the end position downwards, that is, it is as far downwards as allowed by the geometries of the guide rail 9 and the guide member 10. In this position of the surface element, the two cams 13, 14 abut each other, so that a displacement of the surface element 2 according to in the drawing right is not possible. In this way, an accidental slipping out of the surface element from the bearing 7 is reliably prevented.

Now, if the surface element 2 is to be removed deliberately, the surface element is pivoted by an operator slightly counterclockwise upwards. In this case, the cam 14 moves downwards, so that it no longer abuts the cam 13. The surface element 2 with the guide element 10 can then be pushed out of the guide rail 9 to the right in the drawing.

In the picture according to FIG. 6 also can be seen the Wraseneintrittsöffnungen 15 on the surface element. Through this Wraseneintrittsöffnungen 15 of rising from the cooking fumes is sucked into the hood 1. Directly behind the Wraseneintrittsöffnungen 15 is not shown fat filter.
