Description

The invention relates to a kitchen appliance with a kitchen cabinet and a combination appliance with a hob and extractor hood.

In a cooker hood that operates in recirculation mode, the air circuit in the cooker hood ends with an odor filter that the air must pass through before being released back into the room in which the cooker hood is operating. This filter must be changed regularly to ensure that it functions properly.

Currently, in the case of cooktops with integrated extractor devices, odor filters, which can also be referred to as recirculation filters and which are usually made of activated carbon, are arranged in an air duct that is connected to an extractor housing and extends vertically downwards at the rear end of a kitchen cabinet in which the cooktop and the extractor device are installed. In the middle area of the height of the air duct, a drawer for the recirculation filter is provided. Such a cooktop with integrated extractor device is, for example, in the WO 2018/036800 A1 This position of the recirculation filter allows the use of a large-capacity filter. However, this solution requires dismantling a large number of furniture parts in order to replace the filter.

In addition, EN 3 214 926 A1 , DE 20 2005 002 589 U1 and DE 20 2006 003 321 U1 Each of these describes extractor hoods that can be used with a cooking area.

The object of the present invention is therefore to provide a solution which, with a simple construction of a hob with an integrated extractor device, allows easy handling, in particular easy changing of the odor filter.

The object is achieved by a kitchen appliance having the features of claim 1.

According to the invention, a combination device is understood to be a device that has a hob with an integrated extractor device and that is designed for permanent installation in a kitchen unit, in particular a kitchen base unit. The combination device has at least one intake opening through which air can be sucked into the interior of the combination device and in particular into a housing of the combination device and particularly preferably into a fan housing. The at least one intake opening can be incorporated into the hob or be adjacent to the hob.

The combination device has a housing with an air outlet opening. According to the invention, the components of the extractor device and the internal components of the hob, such as heating modules and control electronics, are accommodated in the housing. The housing can be a housing that is closed at the sides and at the bottom. In this case, the housing has a tub shape that is open at the top. However, the housing can also be a housing that is at least partially open at the sides. For example, the housing can only consist of a base and two side walls. Furthermore, the open housing can consist, for example, of a base, corner struts that extend upwards at the corners of the base, and an upper frame, or of a base and side frames that extend upwards from the base. The housing can be covered at the top by a cover plate of the hob, which is usually made of glass or ceramic.

Furthermore, the combination device has a blower, which can also be referred to as a fan. According to the invention, the blower comprises a blower housing with a fan wheel accommodated therein. The blower housing can, for example, be a Spiral casing. The blower casing has an intake opening and an air outlet opening. The blower is accommodated in the casing of the combination device. The casing has an air outlet opening through which air that is emitted from the blower, in particular the air outlet opening of the blower casing, can leave the casing of the combination device.

The combination device also has an odor filter. An odor filter is a filter for filtering out odorous substances. In particular, the odor filter can be an activated carbon filter. The odor filter can also be referred to as an odor filter element or recirculation filter. Although the invention is described below essentially with reference to a single odor filter, it is also within the scope of the invention for the combination device to have several odor filters.

According to the invention, the odor filter is located in the front area of the combination device.

Directional information such as front, back, top and bottom refer - unless otherwise stated - to a combination device and its parts in the assembled state. In particular, the directional information refers to a combination device that is built into a kitchen unit, in particular a kitchen base unit. The front side refers to the side of the combination device that faces the user. The back side is the opposite side, which usually faces a wall in the room.

An odor filter that is located near the front of the combination device or partially in the front of the combination device is referred to as being located in the front area of the combination device. In particular, access to the odor filter is not covered at the front by other components of the combination device.

By arranging the odour filter in the front area of the combination device, it can be easily accessed by the user. Access to the odour filter is necessary for the user because the odour filter must be changed or regenerated at regular intervals. To do this, the user must remove the odour filter from the combination device. Since the front Since the area of the combination device is usually only covered by a cover, for example the front of a kitchen cupboard, only this cover needs to be removed to access the odour filter. The handling of the combination device is therefore simplified.

The combination device preferably has a filter holder for the odor filter. The filter holder can be a slot or a recess in a wall of the housing. Preferably, however, the filter holder comprises at least one guide element. The guide element can be at least one rail or a frame.

According to one embodiment, the filter holder for the odor filter is movably mounted. In particular, the filter holder is movably mounted on the housing of the combination device. Alternatively or additionally, the odor filter can be movably held in the filter holder. In this case, the odor filter is detachably held in the filter holder, i.e. can be removed from the filter holder. Because the filter holder or the odor filter is movably mounted in the filter holder, the odor filter can be moved relative to the combination device and thus removed from the combination device and, for example, cleaned or replaced.

According to one embodiment, the filter holder is located in the housing of the combination device and a filter surface of the odor filter is located in the filter holder on the front of the housing. A filter surface is a surface of the odor filter that is transverse to the flow direction and in particular perpendicular. Alternatively, one side of an edge of the filter holder can be on the front. In the case of a filter holder that represents a frame, one side of the frame is on the front. The filter holder extends from this side to the rear, i.e. into the housing of the combination device. In both embodiments, the filter holder is arranged so that it is accessible from the front. A handle can be provided on the side of the edge that is on the front.

According to one embodiment, the filter holder is mounted displaceably on the housing. In particular, the filter holder is mounted on the housing of the combination device and can be pulled out of it.

According to the invention, the odor filter is located at the air outlet opening of the housing. The air outlet opening can be located at the front or in one of the side walls of the housing. In the case where the air outlet opening is located at the front of the housing, the air outlet opening can represent the exhaust opening through which air is released from the combination device into the environment; in this case, a grille or a recess can be provided on the kitchen unit in which the combination device is installed.

According to a further embodiment, the combination device has an air line that is connected to the air outlet opening of the housing and leads to the blow-out opening of the combination device. This embodiment allows the location at which the air exits the combination device to be spaced apart from the location at which the air exits the kitchen appliance in which the combination device can be integrated. For example, the air can be emitted in a foot area of the kitchen furniture instead of at the height of the combination device. In addition, by providing an air line, for example in a housing in which the air outlet opening is provided on a side wall of the housing, the blow-out opening can be arranged on the front of the kitchen appliance in which the combination device is integrated.

According to one embodiment, an air duct is arranged between the fan and the air outlet opening of the housing. The odor filter can be arranged at the end of the air duct. If the odor filter is at the end of the air duct, it is arranged at the air outlet opening of the housing. By providing an air duct, the position of the odor filter in the housing can be selected so that it can be easily removed from the front.

Advantages and features described with respect to the combination device used according to the invention also apply - where applicable - to the kitchen appliance according to the invention and vice versa and are therefore only described once if necessary.

According to the invention, the kitchen appliance comprises at least one worktop. The worktop can be the top of a kitchen base unit of a kitchen unit or a free-standing kitchen base unit. The extractor hood, which is located below the hob in the combination appliance, is therefore located below the worktop in the kitchen appliance. The odor filter is therefore located in an upper area of the kitchen appliance below the worktop.

The opening for blowing out air on the kitchen appliance can be covered by a grille.

According to the invention, the upper area of the front of the kitchen appliance is formed by a movable front cover. A movable front cover is a panel that is mounted so that it can move. In particular, the kitchen appliance can have a body, the top of which is formed by the worktop and which has cupboard spaces or drawer spaces that are open to the front. The front cover can be mounted so that it can move on the body.

Since the front cover is movable in the upper part of the front of the kitchen appliance, the user can gain access to the odor filter of the combination appliance, which is located in the upper part of the kitchen appliance, by moving the front cover.

According to one embodiment, the front cover is pivotably mounted. The front cover can be designed as a flap, which can be pivoted to make the front of the combination device and in particular the front of the housing of the combination device accessible. Since the odor filter is located in the front area of the combination device, the user can access it by pivoting the front cover and remove or replace the odor filter.

According to a further embodiment, the front cover is mounted so that it can move. The front cover can be mounted on rails that run along the sides of the combination device. By sliding the front cover forwards, i.e. by pulling it out, the user can gain access to the odor filter.

According to a further embodiment, the front cover is mounted so that it can be removed. In this case, the front cover can be locked into the body, for example from the front, in a drawer space in which the combination device is accommodated in the body.

According to the invention, the passage opening is located at the height of the combination appliance in the kitchen appliance. The passage opening can be provided in the front cover or can be formed by the front cover. For example, the front cover in this embodiment can be a grille.

In Figure 1 a schematic front view of an embodiment of the kitchen device 3 according to the invention is shown. The kitchen device 3 comprises a kitchen cabinet 2, which is designed as a kitchen base cabinet, and a combination device 1, which is built into the kitchen cabinet 2. The combination device 1 comprises a hob 10 and an extractor device 11. The hob 10 comprises a cover plate 100, as well as heating modules (in Figure 1 not shown) and electronic components (not shown) for controlling the hob, in particular the heating modules.

The extractor device 11 comprises a fan 110, of which Figure 1 only the fan housing 111 is visible. The fan 110 and the components of the hob 10 except for the cover plate 100 are accommodated in a housing 12 of the combination device 1. In addition, the extractor device 11 comprises an odor filter 112 which is accommodated in the housing 111 of the combination device 1.

The kitchen cabinet 2 has a worktop 20 which forms the top of the kitchen appliance 3. A cover plate 100 of the hob 10 is accommodated in the worktop 20. This will be explained in more detail later with reference to Figure 2 described. Below the worktop 20, the kitchen cabinet 2 has a drawer space 21. Below the drawer space 21, two further storage spaces 22 are arranged, which can also be used for drawers. In the upper drawer space 21, the housing 12 of the combination device 1 with the fan 110 and the odor filter 112 is In addition, in the embodiment according to Figure 1 an air line 113 is arranged in the drawer space 21, via which an exhaust opening 1130 is formed.

In the Figure 2 A further embodiment of the kitchen appliance 1 according to the invention is shown. This embodiment differs from the embodiment according to Figure 1 by the fact that no air duct is provided in the drawer space 21. The exhaust opening is located in the Figure 2 shown embodiment on the front of the housing (in Figure 2 not visible). In the Figure 2 To make the components easier to recognize, the housing of the combination device 1 is not shown.

But how Figure 2 As can be seen, a recess 200 is made in the worktop 20. The combination device 1 is inserted in this recess 200. In the assembled state, the cover plate 100 of the hob 10 lies in the recess 200. A recess 1000 is made in the cover plate 100. The recess 1000 is in the middle of the cover plate 100. Below the cover plate 100 is the fan 114, from which in Figure 2 only the fan housing 111 is visible. A front cover 210 is arranged on the front of the drawer compartment 21, which closes off the drawer compartment 21 at the front. At the rear, the kitchen appliance 3 is attached to a room wall R.

In Figure 3 a schematic plan view of a combination appliance 1 with a first embodiment of the extractor device 11 is shown.

In this view, in addition to the extractor device 11, the housing 12 of the combination device 1 and the kitchen cabinet 2 in the area of the drawer space 21 are shown schematically. The hob 10 is not shown in this illustration. However, the alignment of the components of the extractor device 11 to the hob 10 is shown in Figure 8 visible, which is a schematic front view of the embodiment according to Figure 3 shows. In Figure 3 The electronics of the combination device 1 are arranged in the housing 12 on the floor. As can be seen from Figure 3 In the first embodiment of the extractor device 11, the fan 110, which has a fan wheel 114 and a fan housing 111 surrounding it, is accommodated in the housing 12, which has a rectangular cross section. The fan housing 111 is so aligned so that the air outlet opening 1110 of the blower housing 111 is directed towards a side wall of the housing 12. An odor filter 112 is arranged downstream of the air outlet opening 1110 in the direction of flow. In the embodiment shown, this is arranged between the blower housing 111 and the side wall of the housing 12. An air outlet opening 120 is introduced into the side wall of the housing, which is covered on the inside by the odor filter 112. The odor filter 112 thus extends perpendicular to the front side 14 of the housing 12 of the combination device 1. The odor filter 112 is held in a filter holder 1120. This extends to the front side 14 and through it. For this purpose, in the embodiment shown, a passage opening 121 is introduced into the front side 14 of the housing 12. In a housing 12 that is an open housing, it is not necessary to provide a passage opening, since the odor filter 112 or the filter holder 1120 is accessible through the open front of the housing. An air line 13 is arranged on the outside of the side wall of the housing 12 in the area of the air outlet opening 120. In the embodiment shown, this has an angled shape. One end of the air line 13 rests against the air outlet opening 120 of the housing 12 and the other end forms the exhaust opening 1130 of the combination device 1, with the exhaust opening 1130 facing forwards in the embodiment shown.

The housing 12 and the air line 13 are accommodated in the kitchen cabinet 2. At the front, these components of the combination device 1 are covered by the front cover 210, which closes off the drawer space 21 at the front. In the embodiment shown, the front cover 210 is a grille. However, it is also within the scope of the invention for the front cover 210 to be a plate in which a passage opening (not shown) is made in the area of the blow-out opening 1130. The air flow L can exit the kitchen device 3 to the front through the front cover 120 or the passage opening provided therein.

After the front cover 210 has been removed from the kitchen cabinet 2, pulled out to the front or folded down, the front 14 of the housing 12 is accessible. This allows the user to access the filter holder 1120. For this purpose, for example, a handle on the front of the filter holder 1120 The filter holder 1120 and thus the odor filter 112 can thereby be removed from the combination device 1 and the kitchen appliance 3.

In Figure 4 an embodiment of the combination device 1 is shown with a second embodiment of the extractor device 11. This second embodiment differs from the one shown in Figure 3 shown embodiment only in that in the second embodiment the odor filter 12 is arranged outside the housing 12 in the area of the air outlet opening 120. The further structure corresponds to that of the first embodiment, so that this structure is not explained again, but reference is made to the description of the first embodiment.

In the Figure 5 an embodiment of the combination device 1 with a third embodiment of the extractor device 11 is shown. The third embodiment differs from the first and second embodiments in that the fan housing 111 has a different orientation and that no air duct is provided. In the third embodiment, the fan housing 111 is aligned so that the air outlet opening 1110 is directed forwards, i.e. towards the front 14 of the housing 12. An odor filter 112 is arranged at the air outlet opening 1110. This is located in the housing 12 in an air outlet opening 120 which is introduced into the front 14 of the housing 12. The further structure corresponds to that of the first embodiment, so that this structure will not be explained again, but reference is made to the description of the first embodiment.

In the Figure 6 an embodiment of the combination device 1 is shown with a fourth embodiment of the extractor device 11. The fourth embodiment differs from the third embodiment only in that the odor filter 112 is arranged outside the housing 12 and thus covers the air outlet opening 1110 to the front. In Figure 7 a schematic front view of the fourth embodiment is shown.

Also in the third and fourth embodiments, the odor filter 112 can be removed from the front after opening or removing the front cover 210 from the housing or from the drawer space 21.

The present invention thus provides a combination appliance and a kitchen appliance in which the odor filter is arranged in such a way that it can be removed and replaced from the front of the hob. In addition, the odor filter is preferably located in or on the housing of the combination appliance. The circulation of the air in the combination appliance is directed in such a way that it leaves the housing of the hob either at the side or at the front.

A front cover of the kitchen cabinet in the upper area can be a false drawer or a removable panel to allow access to the odor filter. The front cover can, for example, be removed or pulled out like a drawer.

The combination device has a housing in which the components of the extractor device and at least the internal components of the hob are accommodated. The air enters the housing at the level of a cover plate of the hob and reaches the fan of the extractor device, in particular the fan housing, which can be a spiral housing, for example. In the spiral housing, the air is guided to the odor filter, which is preferably an activated carbon filter, and exits via this filter. According to one embodiment, the odor filter is held in the combination device like a drawer. In particular, rails can be provided at the outlet of the fan housing or the housing of the combination device. In an embodiment in which the air outlet of the fan is located laterally in the combination device, the air is preferably diverted via an air line, which can be a corner piece, for example, so that it can exit to the front.

The present invention makes it possible to replace the odor filter in a simple manner. In addition, the installation of the combination device is also easier and faster due to the reduction in the number of parts.
