Description
Technical Field
The invention relates to a cooking fume extractor for a hob and to a combined installation having a hob with a cooking fume extractor.
Background
In order to suck and clean the steam and smoke generated on the cooktop during cooking, it is known to provide a cooking fume extraction device which sucks the steam and smoke downwards from the space above the cooktop. Such a range hood is also known as a slot fan or a countertop fan.
The cooking fume extraction device can be at least partially integrated into the hob or arranged adjacent thereto.
The range hood has an air inflow opening through which air is drawn downward. At least one filter element is arranged in the flow direction between the air inlet opening of the cooking hood and the air inlet opening of the fan housing for separating dirt from the drawn-in air. The at least one filter element can be arranged in a carrier device which is introduced in a removable manner into the air inflow opening.
A disadvantage of such a cooking fume extraction device is that it must have a certain height due to the at least one filter element arranged above the fan housing. Since the cooking fume extractor is usually installed in kitchen furniture, the installation space required for the cooking fume extractor reduces the space available in the kitchen furniture, for example for drawers.
Disclosure of Invention
The object of the present invention is therefore to provide a solution in which the cooking fume extraction device has a low height and nevertheless reliably removes dirt from the vapor and smoke drawn in with a simple construction.
According to a first aspect of the invention, this object is achieved by a cooking fume extraction device for a hob, having an air inflow opening through which air is drawn in downwards and a fan, which has a fan wheel, a motor and a fan housing, an air inlet opening being provided in the upper side of the fan housing. The cooking fume extractor is characterized in that the means for separating dirt in the cooking fume extractor are arranged only in the flow direction behind the air inlet opening of the fan housing.
One device is referred to as a cooking fume extraction device for cooktops, by means of which vapors and fumes, also referred to below as air or contaminated air, can be extracted and cleaned from the space above the cooktop.
The directional explanations, such as above and below, relate, unless otherwise stated, to the cooking fume extraction device in the installed state in which the air inflow opening is in the upper side of the cooking fume extraction device.
The cooking fume remover has an air inflow opening. The range hood can also have a plurality of air inflow openings.
The air inflow opening can be formed, for example, by a recess in the hob, which is arranged above the air inlet opening of the fan housing. Air is drawn downward through the air inflow opening. Air, in particular contaminated air, is thus sucked in from the space above the hob and is guided downwards. The air passes from the air inflow opening to the fan, by which a suction force for drawing in the air is generated. The cooking fume extractor is therefore provided with a fan. It is within the scope of the invention for the cooking fume extractor to have a plurality of fans, in particular two fans. The invention is described below for better understanding only with the aid of a cooking fume extraction device having a fan. The fan is arranged below the air inflow opening and preferably below the hob. The fan has a fan wheel, a motor, and a fan housing. The fan is in particular a radial fan. The fan housing is preferably a spiral housing, which can also be referred to as a spiral housing.
The fan wheel is driven by a motor. The fan wheel has, in particular, curved blades on the outer circumference, which extend in the axial direction of the fan wheel. The blades can for example be bent back relative to the direction of rotation of the fan wheel. The motor can be received in the fan wheel, that is to say surrounded by the blades. The axis of the fan wheel is in the vertical. An air inlet opening is provided in the upper side in the fan housing. The axis of the fan wheel is preferably in the middle of the air inlet opening. The air inlet opening is located inside the fan wheel in a perpendicular projection to the fan wheel. In particular the blades of the fan wheel are outside the vertical projection of the air inlet opening. Furthermore, the fan housing preferably has an air outlet opening, which is located, for example, on an outer wall of the fan housing. It is particularly preferred for the spiral-shaped housing that the air outlet opening is at the end of an air outlet channel which is connected to a receiving space in which the fan wheel is received. In the air inlet opening and/or the air inflow opening a protective grille can be arranged, which prevents a user from accessing the motor and the fan wheel from above.
The cooking fume extractor is characterized in that the means for separating dirt in the cooking fume extractor are arranged behind the air inlet opening, the fan wheel, only in the flow direction. Surfaces or elements on which dirt, in particular liquid dirt, such as grease or water, is separated from the air are referred to as means for separating dirt. The dirt can accumulate on or flow out of the device and can be guided, for example, to a collecting region. The blades of the fan wheel can also be used as separating means, wherein dirt is only separated here, but is usually removed again from the fan wheel by rotation of the fan wheel.
In this way, the arrangement of the component in the flow direction after the air inlet opening of the fan housing reduces the installation space required in the flow direction before and in particular above the air inlet opening of the fan housing. In addition, in contrast to known cooking fume extraction devices in which the filter element is arranged in the flow direction upstream of the air inlet opening, the flow to the air inlet opening and also to the fan wheel is improved. The fan wheel can thus be operated at a lower speed and nevertheless reliably draws air into the cooking fume extraction device. Here, noise development is minimized.
Particularly preferably, the means for separating dirt are arranged behind the fan wheel only in the flow direction. In this way, dirt separated, for example, on the blades of the fan wheel can be guided, in particular thrown out, in a simple manner by rotation of the fan wheel to the separating device. In this embodiment, the required structural height for the cooking fume extraction device is also small.
According to one specific embodiment, the fan housing has a radial housing wall and the radial housing wall is a means for separating dirt. For radial fans with a spiral housing, the radial housing wall is the spiral wall of the housing in a receiving region of the fan housing, in which the fan wheel is received. The radial housing wall surrounds a fan wheel arranged in the housing. By means of the motor driving the fan wheel, a negative pressure is generated in the fan by means of the fan wheel, through which air is sucked into the air inlet opening. Furthermore, dirt, in particular liquid particles such as grease and water droplets, are accelerated radially outward by the rotating fan wheel. As a result, the dirt is accelerated toward the radial housing wall of the fan housing, impinges on the radial housing wall and is thereby separated at the radial housing wall. Thus, in this embodiment, the fan functions as a centrifuge. Preferably, in this embodiment, the cooking fume extraction device has no filter element for separating particles, that is to say no grease filter. The cooking fume extractor can therefore also be referred to as a filterless cooking fume extractor. It goes without saying that an odor filter can be provided in or at the cooking fume extraction device, if necessary. However, the odor filter is also preferably arranged after the fan wheel in the flow direction. In particular, the odor filter can be arranged at the air outlet opening of the fan housing. However, it is also within the scope of the invention for the odor filter to be arranged at the end of a channel which is connected in the flow direction behind the ventilation housing.
The fan housing can have an opening on its underside, through which dirt separated off at the radial housing wall and accumulated on the bottom of the fan housing can be discharged.
But preferably at least a portion of the fan housing is releasably secured. In particular, for example, only the radial housing wall can be removed from the cooking hood. In addition, at least a portion of the bottom portion is removable from the range hood. In this case, the outer region of the base is preferably connected in a releasable manner to the middle region of the base. The outer region of the base and the radial side wall are preferably designed in one piece. In some embodiments, only a part of the radial side wall or of the radial side wall and the bottom can be removed, which has the advantage that the bottom or a middle part of the bottom covers the fan wheel from below. The safety of the handling of the device is thereby improved, since the fan wheel can be prevented from being inadvertently accessed by a user when the housing part is removed. Alternatively, at least the radial housing wall and the bottom of the fan housing can be removed from the cooking fume extraction device. In this case, the radial housing wall and the base are preferably designed in one piece, i.e., are not releasably connected to one another or are produced integrally. In this embodiment, the radial housing wall and thus the base can also be fastened to the upper side of the fan housing, which can also be referred to as the cover. The fastening can be performed, for example, by means of a snap connection. As an alternative, the radial housing wall and, in addition, the base can also be fastened to the underside of a hob, under which the cooking fume extraction device is arranged. In this case, the fan housing has no upper side or cover.
In this way, at least one part of the fan housing and in particular at least one part of the radial housing wall and the base can be removed from the cooking fume extraction device, this part of the fan housing can be cleaned in a simple manner. In particular, this part of the fan housing can be cleaned in a dishwasher.
According to a further preferred embodiment, the fan wheel is also releasably fixed in addition to at least a part of the fan housing. Preferably, the fan wheel is fixed to the motor.
Since the dirt is at least partially separated from the contaminated air which passes through the fan wheel and is accelerated by the fan wheel, for example condensed there, an embodiment is advantageous in which the fan wheel is also releasably fixed in addition to the part of the fan housing. In particular, the fan wheel can be removed and, if appropriate, cleaned in a dishwasher.
According to another embodiment, the motor can be fixed in a releasable manner in addition to the part of the fan housing and the fan wheel. The motor can be fastened to the cooking hood, for example, by means of a fan housing. In particular, the motor can be fastened to the bottom of the fan housing, and the fan housing can be fastened to the hob in a releasable manner. Alternatively, the motor fixed to the base of the fan housing can be releasably fixed to the cover of the fan housing via the base and the radial housing wall.
According to one embodiment, the releasable part of the fan housing and the fan wheel are a unit that can be preassembled or can be preassembled. In particular, the detachable part of the fan housing and the fan wheel can be removed as a unit from the cooking fume extraction device and fixed thereto. This facilitates handling, in particular cleaning.
According to another embodiment, the motor is an additional part of the preassembled or preassembled unit consisting of the detachable part of the fan housing and the fan wheel. In this embodiment, the motor is preferably designed in a manner fixed to the dishwasher. For example, the motor can be received in a waterproof housing.
According to another embodiment, the cooking fume extractor comprises an air guide channel which extends between an air inflow opening of the cooking fume extractor and an air inlet opening of the fan housing. The air guide channel, which can also be referred to as a chimney, can be introduced into a recess of the hob or the work plate. The upper edge of the air guide channel forms an air inlet opening of the cooking hood. In the case of the cooking fume extractor according to the invention, in a contaminated state, contaminated air flows through the cooking fume extractor as far as the fan wheel, which in this embodiment does not reach the cooking fume extractor or other components of the hob and these other components are thus protected from contamination.
According to one embodiment, the fan wheel is capable of operating at a speed of at least 1000 revolutions per minute. Such a speed is used, for example, when the fan wheel has a diameter of 160 mm. This speed ensures that dirt which has been separated off at the fan wheel is reliably accelerated to the radial housing wall. However, the fan wheel can also be operated at other speeds. In particular, the speed is set such that a reliable detachment of dirt from the fan wheel is ensured by the rotational speed.
According to another aspect, the invention relates to a combined device comprising a hob and at least one cooking fume extraction apparatus according to the invention.
The features and advantages described in connection with the cooking fume extraction device, as far as applicable, apply correspondingly to the combination device and vice versa and are described only once if necessary.
In the case of the combined device, the air inflow opening of the cooking hood is preferably formed by an opening in the hob or by an air guide channel introduced into the opening.

Detailed Description
In fig. 1, an embodiment of a combination device 1 according to the invention is shown in block diagram form. Only half of the combined device 1 is shown in fig. 1. The combined equipment 1 consists of a cooking bench 4 and a fume exhaust device 2. In the embodiment shown, the cooking fume extraction means 2 comprises a fan 3 and an air guiding channel 21. The cooking hood 2 has an air inlet opening 20, which in the embodiment shown is formed by the upper edge of an air guide channel 21.
In the embodiment shown, the hob 4 consists of a cover plate 40 and a heating module 41, only one of which is visible in fig. 1. In the embodiment shown, the heating module 41 is arranged below the cover 40. The heating module 41 can be an induction heating module. However, it is within the scope of the present invention that the heating module 41 be an electrical module or a gas module. In the latter case, the heating module 41 can be passed through an opening (not shown) in the cover 40 of the hob 4. In the embodiment shown, a recess 42 is introduced in the middle of the cover plate 40. The recess 42 can be a rectangular or circular recess. In the embodiment shown, the air guide channel 21 of the cooking fume removal device 2 is introduced into the recess 42. The air guide channel 21 has a height which corresponds to the distance between the upper side of the cover plate 40 and the lower side of the heating module 41.
The fan 3 of the cooking fume extractor 2 is arranged below the cooking top 4. The fan 3 has a fan housing 30, a fan wheel 31 and a motor 32. The motor 32 and the fan wheel 31 are received in the fan housing 30. The fan housing 30 is preferably a spiral housing. An air inlet opening 303 is provided in an upper side of the fan housing 30. The air inlet opening 303 is introduced in the middle of the upper side of the fan housing 30. For a spiral housing, the air inlet opening 303 is arranged in the middle of the surface of a receiving space 300 (see fig. 2), in which receiving space 300 the fan wheel 31 is received. The fan 3 is arranged in the cooking hood 2 in such a way that the air inlet opening 303 is located below the air inlet opening 20 and preferably in the air inlet opening 20 in a perpendicular projection of the air inlet opening 20 onto the air inlet opening 303.
The motor 32 of the fan 3 is arranged below the air inlet opening 303. The motor is thus below the air inflow opening 20 of the cooking fume remover 2. The motor is connected to the fan wheel 31 by means of a fixing means 33, for example by means of a shaft. The fan wheel 31 has on its outer radial periphery blades 310 which extend in the vertical direction. The connection between the blades 310, which can be held on a blade ring (not shown), and the motor 32 or the fixing means 33 can be realized by tabs or disks (not shown). The motor 32 can additionally be connected to the upper side of the fan housing 30 or to the lower side of the heating module 41 via the fastening means 22.
The fan housing 30 has at least one base 301 and a radial housing wall 302, which can also be referred to as a side wall or an outer wall. The fan housing 30 can additionally have an air outlet channel 307 (see fig. 2), at the end of which an air outlet opening 305 is provided. Preferably, the fan housing 30 has a cover 306 that covers at least the receiving space 300 upward. The cover 306 bears against the underside of the heating module 41 and can be connected thereto.
The fan wheel 31 has a diameter which is smaller than the diameter of the fan housing 30 and in particular smaller than the diameter of the receiving space 300 of the fan housing 30. The blades 310 of the fan wheel 31 are therefore spaced apart from the radial housing wall 302.
Apart from the air guide channel 21 and the protective grille 304 which may be arranged at the air inlet opening 303, no further elements, in particular no filter elements, are present between the air inflow opening 20 and the fan wheel 31. Therefore, the fume extraction 2 of the combined installation 1 can also be referred to as a filter-less fume extraction 2. However, this does not exclude that an odor filter (not shown) is arranged at said air outlet opening 305 or downstream of it in the flow direction.
When the cooking hood 2 is operated, the fan wheel 31 is driven by the motor 32. Thereby creating a suction force by which air is drawn into the cooking fume extraction device 2 via the air inflow opening 20. Here, the air passes through the air guide channel 21 and reaches the fan housing 30 via the air inlet opening 303. There, the air is deflected radially outwards by the rotation of the fan wheel 31 and the blades 310 arranged thereon. The air is directed radially outward through the spaces between the blades 310 and accelerated toward the radial housing wall 302. Dirt, in particular grease or water, which is present in the air sucked out from above the hob 4 is thus thrown against the radial housing wall 302. Dirt that has been separated off at the blades 310 of the fan wheel 31 is also thrown against the radial housing wall 302 by the rotation of the fan wheel 31. These contaminants are usually liquid contaminants, such as grease or other liquids. As a result, these liquid contaminants flow downward on the radial housing wall 302 and accumulate on the bottom 301. For contaminants with low viscosity, they can also accumulate on the radial housing wall 302 and adhere there.
For cleaning the cooking fume extraction device 2, at least one part of the fan housing 30, in particular the base 301 and the radial housing wall 302, can be removed together with the fan wheel 31 according to the invention. Alternatively, the motor 32 can be removed in addition to at least a portion of the fan housing 30 and the fan wheel 31. In this embodiment, the parts of the fan housing 30, the fan wheel 31 and the motor 32 are also designed to be removable together.
In the first case, in which only a part of the fan housing 30 and the fan wheel 31 should be removed from the cooking fume extraction device 2, the releasable part of the fan housing 30 is preferably the part comprising the base 301 and the radial housing wall 302. However, it is also possible for the entire fan housing 30, that is to say the base 301 of the fan housing 30, the radial housing wall 302 and the cover 306, to be removable. In this case, the air inlet opening 303 is preferably dimensioned such that the motor 32 can be guided through the air inlet opening 303 into the interior of the fan housing 30. In the case where at least a part of the fan housing 30 and the fan wheel 31 are detachable, the fan wheel 31 may be supported in a guide mechanism on the bottom 301 of the fan housing 30, for example, so as to be rotatable. The releasable connection to the cooking fume extraction 2 can be made by means of a fastening means 33, by means of which the fan wheel 31 and the fan housing 30 are fastened to the motor 32. In addition, the fan housing 30 or a releasable part of the fan housing 30 can be fastened to the underside of the heating module 41 of the hob 4 by means of fastening means 22.
In the case that the motor 32 can also be removed from the cooking fume extraction 2 in addition to at least one part of the fan housing 30 and the fan wheel 31, the fan housing 30 can have a cover 306 and this cover forms a unit with the base 301 and the radial housing wall 302. In this embodiment, the entire fan housing 30, the fan wheel 31 and the motor 32 received therein are then removed from the cooking fume extraction device 2. In this embodiment, the removable unit can be releasably fixed to the underside of the hob 4 by means of the fixing means 22.
A user of the combination 1 can thus take at least part of the cooking fume extraction means 2 down and clean it. The air guide channel 21 is preferably removable from above from the recess 42 of the hob 4. The air guide channel 21 is placed on the upper side of the fan housing 30 in the introduced state. Furthermore, the air guide channel 21 can have an outwardly facing flange (not shown) on its upper edge. In the inserted state of the air guide channel 21, this flange can rest on the edge of the recess 42 of the hob 4.
Fig. 2 shows a perspective, partially sectional view of an embodiment of a combination device 1 according to the invention. The embodiment according to fig. 2 corresponds substantially to the embodiment according to fig. 1. In the sectional view according to fig. 2, only a part of the fan wheel 31, in particular the blades 310, can be seen. The blades 310 are connected to the motor 32 by means of a support or disc, which is not shown in fig. 2, together with the motor 32.
In the embodiment shown, the fan housing 30 has a receiving space 300. In this receiving space 300, which has a spiral-shaped cross section, the fan wheel 31 is received. On one side, on the left in fig. 2, the receiving space 300 is enlarged and transforms into an air outlet channel 307, which ends with an air outlet opening 305 of the fan housing 30. A schematic top view of such a fan housing 30 is shown in fig. 2 a.
In the embodiment according to fig. 2, the fan housing 30 has a cover 306. On the upper side of the cover 306, an upwardly projecting wall is schematically shown, which can serve as a fastening means 22 of the fan housing 30 on the hob 4. In the embodiment shown in fig. 2, the recess 42 in the hob 4 is a rectangular recess which extends in the depth direction of the hob 4 in the center of the hob 4. In this embodiment, the connection between the hob 4 and the fan housing 30 is at a recess 42 on the underside of the cover plate 40 of the hob 4. Furthermore, as in the embodiment according to fig. 1, the air guide channel 21 is introduced into the recess 42. For better identifiability, the air guide channel 21 is shown in fig. 2 in the lifted state. In the inserted state, the underside of the air guide channel 21 rests on the cover 306 of the fan housing 30.
The air inlet opening 303 of the fan housing 30 is introduced in the cover 306 and thus in the upper side of the fan housing 30. In the embodiment shown, a protective screen 304 is arranged in the air inlet opening 303, which protective screen serves as an intrusion-prevention device. The air inlet opening 303 is aligned with the air inflow opening 20 formed by the upper edge of the air guide passage 21.
The fan 3 is shown in more detail in fig. 3 in the area of the air inlet opening 303. As can be gathered from this figure, in the embodiment shown, the diameter of the fan wheel 31 is larger than the diameter of the air inlet opening 303. The axis of rotation of said fan wheel 31 is in a vertical line and arranged in the middle of the air inlet opening 303. The motor 32, by means of which the fan wheel 31 is driven, is in the axis of rotation of the fan wheel 31. The fan wheel blades 310, which are situated in the vertical direction on the outer circumference of the fan wheel 31 and thus parallel to the axis of rotation of the fan wheel 31, extend from the outer circumference of the fan wheel 31 curvedly inwards in the radial direction. Here, the extension of the vane 310 in the radial direction is designed such that the inner end of the vane 301 is on the outer periphery of the air intake opening 303.
Thus, the present invention relates to a combination between a hob, which can be an electric, induction or gas hob, and an integrated cooking fume extraction device, which can also be referred to as a countertop ventilation device. With the invention, the device is of compact design. Nevertheless, in the combined device, a number of functions, such as, in particular, fans, grease separating devices and, if appropriate, odor filters, are integrated in a small space. The width and depth of the combined device is typically given by the furniture industry. The height of the combination device is decisive, since it is inserted into the space of a kitchen furniture, in which, for example, drawers are provided.
Known combination devices with a cooking hood, which is integrated with the hob and which has, for example, an expanded metal filter for filtering out grease, mostly have a height of approximately 20 cm. The invention provides a cooking fume extractor and a combination device which allow liquid contaminants to be reliably filtered out in a small installation space and in particular at a small height.
The invention is based on the recognition that this object can be achieved by: the range hood is a filter-less device.
In the present invention, instead of using a standard grease filter, a centrifugal separation device that is at least partially removable is used. In particular, the fan, which can also be referred to as a fan, serves at least partially as a separating device. The fan comprises three main components. In particular, the fan preferably comprises an electric motor which drives a fan wheel, a fan wheel and a fan housing, wherein air is sucked into the cooking fume extraction device by rotation of the fan wheel and the fan housing can be a spiral housing and the fan housing guides the air.
The principle used according to the invention is that of a centrifugal separator. In this case, steam and fumes, which can also be referred to as grease/water vapor, are sucked into the fan and are thrown by centrifugal force onto the fan housing and dirt accumulates there.
According to the invention, the fan can be at least partially removed from below and cleaned in a dishwasher. According to the invention, two interfaces are possible:
in one embodiment, the motor, fan wheel and fan housing are a unit that can be removed and is compatible with a dishwasher. The motor is designed in such a way that it is fixed to the dishwasher;
in another embodiment, the fan wheel and the fan housing are one unit. The motor cannot be removed. The fan wheel is preferably releasably coupled to the motor. In this embodiment, the motor need not be sealed.
In the flow direction upstream of the motor, an upwardly removable air duct, which can also be referred to as a chimney, can be provided, which can also be cleaned and introduced into the recess in the hob.
The odor filter is preferably arranged such that it is arranged relative to the fan wheel such that dirt accelerated by the fan wheel does not reach the odor filter directly. In particular, the odor filter can be arranged at the air outlet opening of the fan housing or at the end of an air duct which is connected to the air outlet opening of the fan housing.
The invention has a series of advantages. It is particularly preferred that all parts are cleanable. Saturation as occurs in conventional grease filters does not occur in the present invention. The cooking fume extractor is particularly suitable for thin liquid-like dirt such as occurs when cooking in asia. The combined device can be manufactured with a small height, for example 12cm or 16cm, and can therefore easily be integrated into kitchen furniture, like for example a kitchen cabinet.
