Description

The present invention relates to an extractor hood comprising at least one housing device which delimits at least one opening to at least one suction section for rising vapors, with at least one removable filter device being arranged in the opening. The filter device is held in the opening in the inserted state by at least two holding devices.

Extractor hoods are often installed over hotplates in order to suck off the greasy vapors that rise during cooking and, in particular, to free them from fat.

In this case, extractor hoods generally have at least one filter or at least one grease filter, through which the rising vapor is sucked into the extractor hood by means of a fan. The air stream freed from fumes and fat is then blown back into the kitchen by means of the fan in a recirculation mode or blown out of the kitchen in an exhaust air mode.

So that you can easily clean the grease filter, for example in the dishwasher, it is usually removed from the extractor hood. The filter should ideally be removed by the user simply, quickly and without tools. The pamphlet DE 10 2018 201 046 A1 discloses an extractor hood with a suction opening and a holding frame for filter elements arranged on the housing of the extractor hood. The holding frame has movable pins which can engage in pin openings on the device housing. In this way, the holding frame can be fastened in the suction opening.

For this purpose, filters have become known, for example, which have webs or hooks on one side that are inserted into corresponding openings in the extractor hood. On the other hand, the filter then has a retractable lock, often also called a catch. By means of such a system, the filter can be reliably attached to the extractor hood and removed quickly and easily. An extractor hood with a filter element, which is connected on one side via a swivel bearing to the housing of the extractor hood and on the other side has a locking means for connection to the housing of the extractor hood, is from the publication DE 10 2012 201 409 A1 known. However, it is disadvantageous that the effective filter area is reduced by the locking components on the filter. In addition, the Locks are often made of plastic, so that the locking mechanism becomes brittle when cleaned in the dishwasher and, in the worst case, can break. In addition, plastic components in the dishwasher often become unsightly over time.

It is therefore the object of the present invention to provide an extractor hood which at least partially does not have the aforementioned disadvantages, the filter in particular being easy to remove and insert and a filter with the largest possible filter surface being able to be implemented.

This object is achieved by an extractor hood with the features of claim 1. Preferred developments of the invention are the subject matter of the dependent claims. Further advantages and features of the invention emerge from the exemplary embodiments.

The extractor hood according to the invention comprises at least one housing device which delimits at least one opening to at least one suction section for rising vapors, with at least one removable filter device being arranged in the opening. This at least one filter device is held in the opening by at least two holding devices in the inserted state. These holding devices are arranged on the housing device in the region of the opening, at least one holding device comprising at least one holding element which can be displaced at least in sections between at least one holding position and at least one removal position.

The extractor hood according to the invention can be provided in various configurations. In particular, it is about the attachment of the filter device in the opening for sucking in vapors. For example, a headroom hood, a freely hanging hood, a flat panel hood or an extractor hood integrated into a piece of furniture can be provided.

The two holding devices for receiving the filter device are in particular provided on opposite sides of the opening, so that holders or holding devices are provided on at least two opposite sides. It is also possible that additional holding devices are provided on other sides of the opening or that the holders are not opposite one another.

The holding devices are arranged or received on and / or in the housing device and / or are formed at least in sections by the housing device. In this case, one and / or both holding devices can preferably also be in one piece or at least partially manufactured in one piece with the housing device and / or connected to it.

The holding position is in particular the position in which the filter or the filter device is received in the opening in the suction section in the operational state. The removal position is in particular the position in which the holding element of a holding device is present when the filter device can be removed from the opening for sucking in vapors or from at least one holding device with a displaceable holding element. The removal position is in particular also the position in which the holding element of a holding device is present when the filter device can be inserted into the opening for sucking in fumes or from the at least one holding device with a displaceable holding element.

The holding element can preferably be displaced by hand from the holding position to the removal position, provision being made in particular that no tools or auxiliary means are required to move the holding element from one position to the other in order to place the filter device in or out of the opening to remove the opening.

Removal of the filter device, in particular tool-free removal, can be advantageous in particular for cleaning the filter device.

Depending on the configuration, however, the holding element can also be transferred automatically, for example by means of a motor, from one position to the other.

The holding devices are arranged on the housing device or assigned to the housing device. In particular, it is preferred that the holding devices are provided exclusively on the housing device, which means in particular that no parts of the holding device are assigned to the filter device or are arranged or provided on it.

The extractor hood according to the invention offers many advantages. A considerable advantage is that the provision of the holding devices on the housing device makes it possible to provide the largest possible filter surface on the filter device. This is made possible in particular by the fact that no components have to be made available for receiving the filter device in the suction section on the filter device. It is thus possible to make the filter device available almost exclusively from filter material.

In conventional filter devices or hoods z. B. a snap or the like is provided on the filter device, which in a corresponding receptacle in the cooker hood engages. On the one hand, such a configuration blocks installation space for filter material. On the other hand, such fastening means for the filter device are then cleaned when the filter device is cleaned, for example in the dishwasher, as a result of which they can become brittle and unsightly relatively quickly. This is not desirable, since it creates optical disadvantages and, in the worst case, the embrittlement of the material may make it necessary to replace the filter device.

In the holding position, the holding element preferably protrudes at least in sections further from the housing device into the opening than in the removal position. The holding element advantageously further comprises at least one support for the filter device. This makes it possible for the filter device to rest on the holding element when it is in the holding position. If the holding element is moved from the holding position to the removal position, the support surface for the filter device is also displaced so that the filter device is no longer held in the holding device with the holding element and can be removed from the suction section downwards.

In expedient developments, the holding element comprises at least one locking lug or is designed as a locking lug. Such a configuration makes it possible to provide a simple way of fixing the filter devices.

The holding device preferably comprises at least one preloading device, the displaceable holding element being preloaded in particular in the holding position. A preloading device can preferably be provided by a spring and / or at least one spring element. By means of such a preloading device, the holding element can then, for example, be pressed into the holding position. If the holding element is then displaced into the removal position by a user against the preload force, the filter device can be removed. As soon as the user lets go of the holding element, it is automatically shifted back into the holding position. Also when inserting the filter device, the retaining element is pushed away or moved into the removal position by the user or by the filter device, so that the filter device is moved into the desired position and then fixed in this position by the spring-back retaining element.

The holding element is preferably shifted rotationally and / or translationally from the holding position into the removal position and vice versa. The movement of the holding element can be linear, for example. But it is also possible that the holding element is hinged on one side and z. B. is tiltable about a pivot axis. In other configurations, a type of bolt can also be provided additionally or exclusively, which also without Preload device can work. The rule is, for example, pushed into the housing to remove the filter and pulled out again when the filter is inserted.

In the removal position, the displaceable holding element is particularly preferably received at least in sections and preferably essentially completely in the housing device. It is also possible that the holding element is received completely in the housing device, depending on the configuration. In particular, it is expedient that the holding element can be moved so far into the housing device and thus out of the opening that the filter device can be removed from the opening of the suction section. In particular, it is possible to insert the filter device into the opening of the suction section as optimally and closely as possible, so that on the one hand a large filter surface and on the other hand a tight connection are made possible.

At least one holding device preferably comprises at least one stop. Such a stop is used in particular to align the filter device. Such a stop can in particular also be designed to be resilient or comprise a preloading device or interact with such a device, so that the stop automatically aligns the filter device in a suitable position in the opening.

The holding element particularly preferably has at least one bevel. Such a view can in particular be designed in the manner of a ramp. It is particularly preferred that the ramp or the bevel is larger or wider in the suction direction of the vapor. It is thus possible in particular for the filter device to be able to automatically move the holding element from the holding position to the removal position when it is inserted. This takes place in that a user, for example, brings the filter device into contact with the holding element and then pushes it further in the direction of the predetermined position. Due to the bevel, the filter device then pushes the holding element out of the holding position into the removal position. As soon as the filter device is in the desired position, the holding element is pushed back by the preloading device, so that the filter device is securely held in the opening.

The filter device preferably comprises filter material through which a flow can flow over essentially the entire longitudinal extent and transverse extent. In particular, the filter device does not comprise any components of the holding device.

Further advantages and features of the present invention emerge from the exemplary embodiments, which are explained below with reference to the accompanying figures.

In Figure 1 is shown purely schematically an extractor hood 1 in a sectional view from the side. The extractor hood 1 here comprises a housing device 2 which forms an opening 3 to a suction section 4 here at the bottom of the extractor hood 1.

A fan device 17 is arranged inside the extractor hood 1 or inside the housing 2, which sucks the rising vapor through the opening 3 and thus through a filter device of FIG. 5 arranged in the opening 3 into the suction section 4 and, in the case shown here, expels it upwards again . Depending on the design of the extractor hood 1, the air flow can be designed in such a way that the vapor which is now filtered is blown out of the kitchen through a corresponding air duct in an exhaust air mode. Depending on the configuration, a circulating air mode can also be provided, with the cleaned air or the cleaned vapor being blown back into the kitchen.

It is also shown that a protective grille 18 is provided inside the extractor hood 1 in the air duct behind the filter device 5, so that a user cannot reach into the fan device 17 even when the filter device 5 is removed.

In the exemplary embodiment shown here, the filter device 5 is designed as a grease filter 19. This grease filter 19 comprises appropriately designed filter material 16 through which the rising vapor is passed. The vapor is freed from fat components by means of the fat filter 19. Depending on the configuration, further filters can also be provided in the extractor hood 1 or combined with the filter device 5. For example, it is also possible for odor filters such as activated charcoal filters to be integrated in addition or in the grease filter device 5 or in the grease filter 19.

So that the filter device 5 can be removed from the extractor hood 1 or the opening 3 of the suction section 4, holding devices 6, 7 are provided on the left and right in the exemplary embodiment shown here, one of which, the left holding device 6 in the exemplary embodiment shown here, is a comprises movable holding element 8, via which the filter device 5 can be removed quickly and easily from the opening 3 of the suction section 4. How this holding device 6 or holding element 8 is designed is explained in more detail in the following figures.

In Figure 2 is an enlarged representation of the area of the opening 3 of the intake section 4 of an embodiment of an extractor hood 1 in a purely schematic sectional view. Here, too, one recognizes the opening 3, in which a filter device 5 is arranged, which is designed here as a grease filter 19. In the air flow direction inside the extractor hood and behind the filter device 5, the protective grille 18 can also be seen here.

Furthermore, in Figure 2 the left holding device 6 and the right holding device 7 can be seen. The two areas of the marked with a circle Figure 2 are in the Figures 3 and 4 shown enlarged in order to better illustrate the functioning of the holding devices 6, 7.

In the Figures 3 and 4 it can be seen that the left holding device 6 comprises a holding element 8 which can be shifted from a holding position 9 to a removal position 10.

The filter device 5 is held by the holding device 6 or by the holding element 8 in the holding position 9 in a predetermined operating position. On the right side, the holding device 7 is configured differently in the exemplary embodiment shown. In this case, this holding device 7 does not include a displaceable holding element 8 here. Depending on the configuration, both sides or the opposing holding devices 6, 7 can also be designed in the same way.

In the exemplary embodiment shown, the right-hand holding device 7 comprises a stop 14, which enables the filter device 5 or the grease filter 19 to be optimally aligned in the opening 3 of the suction section 4. The stop 14 here comprises a pre-loading device 13. This resilient stop 14 aligns the filter device 5 in the opening 3 and, in addition, there is a certain amount of play in interaction with the stop 14 on the left-hand side so that the filter device 5 is easier to use and is always optimally centered in the opening 3.

Basically, the right holding device 7 is provided here by a type of U-profile 20, which provides a support 11 for the filter device 5 and fixes the filter device 5 upwards and downwards.

As already described above, the holding device 6 is configured differently in the exemplary embodiment shown here than the holding device 7 on the right-hand side. The holding device 6 comprises a holding element 8 on the left-hand side, which is shown in FIG Figure 3 is in the holding position 9. The holding element 8 can, however, against the force of a preloading device 13 in an in Figure 4 illustrated removal position 10 are shifted.

If the holding element 8 is in the holding position 9, the holding element of the filter device 5 offers a support 11 so that the filter device 5 is held in the opening 3 of the suction section 4 by the two holding devices 6, 7.

To remove the filter device 5, the holding element 8, which is designed here as a latching lug 12 or comprises a latching lug 12, is pushed further out of the opening 3 in the direction of the housing device 2 or into the housing device 2. This clears the path for the filter device 5 downwards so that it can be removed.

In Figure 4 it is shown that the preloading device 13 has been pushed together by pressing or actuating the holding element 8. When the holding element 8 is inserted or released, the holding element 8 moves back into the holding position 9.

Furthermore, in the Figures 3 and 4 to see that the holding element 8 has a bevel 15. In the exemplary embodiment shown, this ramp-like bevel 15 particularly facilitates the insertion of the filter device 5 into the opening 3.

It is thus possible, among other things, in the exemplary embodiment shown here to first insert the filter device 5 into the holding device 7 on the right-hand side and then simply press it against the holding element 8 by means of the filter device 5.

Due to the bevel 15, the pressure of the filter device 5 against the holding element 8 shifts the holding element 8 from the holding position 9 into the removal position 10, so that the filter device 5 can pass the holding element 8. As soon as the filter device 5 is above the holding element 8, the holding element 8 snaps or snaps or moves back into the holding position 9 and offers a support 11 for the filter device 5.

Because the holding devices 6, 7 are assigned to the housing device 2 or are arranged on it or are integrated into it, it becomes possible to provide the largest possible filter surface on the filter device 5, since there is no space for the provision of fastening mechanisms on the Filter device 5 is lost.
