EXTRACTOR APPARATUS, AND KITCHEN ARRANGEMENT HAVING A HOB AND AN EXTRACTOR APPARATUS
An extractor apparatus includes an extraction body having an extraction side provided with an extraction opening, a rear side opposite the extraction side, and three connecting walls. Each of the connecting walls extends between an edge of the extraction side and an edge of the rear side. At least one of the connecting walls of the extraction body is provided with a blow-out opening for blowing air out. A blower extracts air downwards via the extraction opening.
The present invention relates to an extractor apparatus and a kitchen arrangement having a hob and an extractor apparatus.
It is known to use extractor hoods which are fastened above the hob, for example to a room wall, for cleaning fumes and vapors which are produced when cooking on a hob. These extractor hoods extract the fumes and vapors upwards. Moreover, so-called downdraft ventilation systems or table ventilation systems are also known, which can also be denoted as hob ventilation systems, in which fumes and vapors are extracted downwards. One embodiment of a downdraft ventilation system is described, for example, in DE 10 2010 042 436 A1. An extraction body having a vertical extraction opening which can be extended vertically out of a hob is used in this downdraft ventilation system.
In hob ventilation systems, the rising vapors are extracted downwards or to the side counter to the physical lift thereof. This requires high air speeds or extraction power which are associated with a high level of noise. In the case of large distances between the cooking vessel and the extraction opening, there is no vapor capture or the vapor capture rate is low. Moreover, the majority of hob ventilation systems have difficulty in collecting the rising vapors of taller cooking vessels such as pots. If cross-flows are produced in the room, additionally a significantly reduced vapor collection is noticeable.
It is the object of the present invention, therefore, to provide an extractor apparatus, in particular a hob ventilation system, by means of which the vapors produced when cooking on a hob can be extracted as far as possible and in which at the same time the energy expenditure is reduced.
According to a first aspect, this object is achieved by an extractor apparatus having at least one extraction opening and a blower, via which air is extracted downwards via the extraction opening. The extractor apparatus is characterized in that the extractor apparatus comprises an extraction body having an extraction side, in which at least one of the extraction openings is provided, having a rear side, which is located opposite the extraction side, and having three connecting walls, which each extend between an edge of the extraction side and an edge of the rear side, and in that at least one blow-out opening for blowing air out is provided in at least one of the connecting walls of the extraction body.
An apparatus by which air, in particular contaminated air in the form of fumes and vapors, can be extracted from a hob and/or a worktop is denoted as an extractor apparatus. The extractor apparatus has an extraction opening. According to the invention, a plurality of extraction openings can also be provided on the extractor apparatus. The extractor apparatus additionally has a blower. Air is extracted downwards by means of the blower via the extraction opening. A plurality of blowers can also be provided in the extractor apparatus. However, the invention is described hereinafter with reference to an extractor apparatus comprising one blower. The blower can also be denoted as a fan or extractor fan. The air which is extracted from the hob via the extraction opening is denoted as primary air and, in particular, represents contaminated air in the form of fumes and vapors. The extractor apparatus thus represents a hob ventilation system.
The extractor apparatus has an extraction body. The extraction body represents a hollow body and is also denoted hereinafter as a cassette or extraction channel. Preferably, at least one filter element is received in the extraction body. The extraction body has an extraction side, a rear side opposing the extraction side and three connecting walls which in each case extend between a side edge or upper edge of the extraction side and a corresponding side edge or upper edge of the rear side. The extraction body thus has a box shape which is open to one side, in particular downwards.
Directional information such as top, bottom, front and rear, unless specified otherwise refer to the extractor apparatus in a state mounted to the rear of a hob. The extraction side in this case faces the hob and can also be denoted as the front side of the extraction body. The depth of the extraction body, i.e. the distance between the extraction side and the rear side, is preferably less than the height and the width of the extraction body. Thus the surfaces of the extraction side and the rear side in each case are larger than the surface of the connecting walls. The depth of the extraction body can range, for example, from 3 to 10 cm. In the mounted state of the extractor apparatus, the extraction side is preferably located in the vertical. The at least one extraction opening is provided in the extraction side and thus is preferably located in the vertical.
Preferably, the connecting walls represent two side walls and a top wall of the extraction body. The top wall in the mounted state of the extractor apparatus is the upper side of the extraction body.
The extractor apparatus is also denoted as a downdraft apparatus.
At least one blow-out opening for blowing air out is provided in at least one of the connecting walls of the extraction body. The at least one blow-out opening can be designed in the form of a hole or a slot. However, it is also within the scope of the invention that the at least one blow-out opening is formed in each case by a pipe end or an opening in the lateral surface of a pipe. The blow-out opening in this case can also be denoted, in particular, as a nozzle. The air guidance from the blower to the at last one blow-out opening can be carried out by means of a channel which can have a round or rectangular cross section (flat channel). The air discharged via the blow-out opening is also denoted as the secondary air or secondary fluid.
Thus a directed secondary air flow can be blown out via the at least one blow-out opening. The secondary air flow is also denoted hereinafter as the supply air flow, additional air flow or secondary fluid flow. The secondary air can be fresh air from the room in which the extractor apparatus is operated, fresh air from outside the room, or fumes and vapors extracted from the room and preferably cleaned. An air flow which flows at least over a certain distance in a predetermined direction, due to the geometry and/or arrangement of the blow-out opening and/or the speed at which the air flow is blown out, is denoted as a directed air flow.
Since according to the invention at least one blow-out opening is provided in at least one connecting wall and a directed secondary air flow can be blown out via this blow-out opening, the direction and speed of the primary air flow, which is determined by the blower and the thermal currents on a hob, can be changed or assisted in a targeted manner in at least individual regions. In particular, the primary air flow can be diverted to the at least one extraction opening in the extraction side. As a result, the volume flow extracted via the extraction opening can be increased and/or the requirement for the blower for extracting the primary air can be reduced. Thus the vapor capture rate and thus the efficiency of the extractor apparatus can be increased by means of the present invention. Additionally, the blower can be operated at reduced power, or a smaller blower, i.e. a blower with a lower rated power, can be used. As a result, the development of noise when extracting the primary air can be reduced and the energy requirement is lowered.
According to one embodiment, at least one of the blow-out openings is arranged in the side walls of the extraction body. The blow-out openings are preferably arranged in the lower region of the side walls. The blow-out openings, however, can also be provided over the entire height of the side walls or only provided in the upper region of the side walls. In the case in which the blow-out openings are provided in the side walls, the top wall can represent a closed wall. Preferably, blow-out openings are provided in the two side walls and the arrangement of the blow-out openings in the two side walls is the same. The side walls are preferably located in the vertical. Since the blow-out opening(s) provided therein is/are located in the vertical, a secondary air flow which has at least one horizontal directional component can be discharged via the at least one blow-out opening. For example, the secondary air flow can be discharged in the horizontal. In particular, a secondary air flow directed to at least one of the sides, and preferably both sides, of the extractor apparatus and thus in each case to one of the sides, and preferably both sides, of the hob can be produced via the blow-out opening located in the vertical.
Alternatively or additionally to the blow-out openings in the side walls, at least one of the blow-out openings can be provided in the top wall of the extraction body. Preferably, the blow-out openings are arranged in the side regions of the top wall. Preferably, the blow-out openings in the top wall are arranged symmetrically to the center of the width of the top wall. The blow-out opening(s) which is/are provided in the top wall is/are located in the horizontal.
Since at least one blow-out opening is located in the horizontal, the secondary air can be discharged via the blow-out opening in a direction which has at least one vertical directional component and is oriented, for example, vertically upwards.
The blow-out opening can be located in the edge of the connecting wall which adjoins the extraction side. According to one embodiment, however, the at least one blow-out opening is located adjacent to the edge of the connecting wall which adjoins the extraction side. In this embodiment, the blow-out opening is located spaced apart from the edge of the connecting wall which adjoins the extraction side but in the front region of the respective connecting wall.
Additionally or alternatively to the arrangement of the blow-out opening(s) in the front region of the connecting wall, the at least one blow-out opening can be located adjacent to the edge of the connecting wall which adjoins the rear side. In this embodiment, the blow-out opening is located spaced apart from the edge of the connecting wall which adjoins the rear side but in the rear region of the respective connecting wall.
Additionally or alternatively, it is also possible that the at least one blow-out opening is located in the center of the depth of the extraction body, in particular in the center of the connecting walls between the extraction side and rear side.
Preferably, the at least one blow-out opening extends in a direction which is located parallel to the extraction side. In this embodiment, the blow-out openings can have an elongated shape, in particular they can represent slots. If a plurality of blow-out openings are provided adjacent to one another, these blow-out openings are arranged in series. In the embodiment of the blow-out opening in which this blow-out opening has a circular shape, these blow-out openings are also preferably arranged in series in order to form the extension in the direction parallel to the extraction side.
The at least one extraction opening which is provided in the extraction side can extend in the horizontal direction and/or in the vertical direction. Preferably, the extraction opening represents an elongated opening. In one embodiment, a gap extending in the horizontal direction can be provided as an extraction opening in the upper region of the extraction side. Alternatively or additionally, a plurality of slots extending vertically can be provided in the extraction side as the extraction opening. Alternatively, the extraction opening can also be formed as a peripheral gap in the extraction side. In this embodiment, a flat opening can be provided in the extraction side, a baffle plate being arranged in, or in front of, said opening.
Preferably, the extractor apparatus has at least one filter element for cleaning the air. In particular, at least one grease filter and optionally an odor filter can be provided in the extractor apparatus. In a preferred embodiment, at least one filter element, in particular a grease filter element, is arranged in the extraction body. The filter element is preferably arranged such that it covers the extraction opening from the inside.
The secondary air flow which is discharged via the at least one blow-out opening can be generated by the blower of the extractor apparatus. In particular, a part of the primary air extracted via the extraction opening and optionally cleaned in the extractor apparatus can be branched off via a bypass and supplied to the blow-out openings. In this case, a variable secondary air flow can be formed, i.e. which is dependent on the primary air flow. In this embodiment, optionally the speed of the secondary air flow can be also determined by the geometry of the blow-out openings.
According to one embodiment, therefore, a part of the exhaust air flow can be used in order to influence the vapors in an advantageous manner. In this case, a part of the air optionally cleaned of grease and odors can be removed from the exhaust air flow via a bypass. The air flow which has been extracted and cleaned by the extractor apparatus is denoted within the meaning of the present invention as the exhaust air flow. This air can alternatively be returned into the room in which the extractor apparatus is operated or discharged to the environment. The extractor apparatus thus can be designed as an exhaust air extractor apparatus or a circulating air extractor apparatus.
According to one embodiment, the extractor apparatus has an additional blower which is connected to the at least one blow-out opening. In this embodiment, fresh air can be extracted from the room in which the extractor apparatus is operated, or from the environment, and can be blown out of the blow-out openings as the secondary air flow. In this embodiment, therefore, a constant secondary airflow can be generated. The additional blower can extract, for example, a fresh air flow from the base cabinet in order to influence the vapors in an advantageous manner. In this case, clean air is extracted from the kitchen base cabinet. Alternatively, clean air can be extracted from outside.
According to a further aspect, the invention relates to a kitchen arrangement having a hob and at least one extractor apparatus which represents an extractor apparatus according to the invention.
Advantages and features which are described relative to the extractor apparatus also apply — if applicable — to the kitchen arrangement according to the invention and vice versa, and thus are only described once where appropriate.
The kitchen arrangement has a hob and at least one extractor apparatus. The hob and the extractor apparatus can be installed in a worktop. In this case, the hob and extractor apparatus(es) can be incorporated in a common recess of the worktop. However, it is also within the scope of the invention that the at least one extractor apparatus and the hob can be incorporated in separate recesses of the worktop. The hob and the extractor apparatus can represent a common kitchen appliance or can be provided as separate appliances.
At least in an operating position, the extraction body of the extractor apparatus protrudes upwards beyond the plane in which the hob is located, in particular the plane of the worktop.
Since the at least one extraction opening is provided in the extraction side and it faces the hob, and the blow-out opening(s) is/are provided in the connecting walls of the extraction body, the extraction opening is closer to the hob than the at least one blow-out opening. Additionally, the primary air flow which is extracted via the extraction opening can be influenced in the vicinity of the extraction opening. Thus the invention differs from extractor apparatuses in which a supply air flow is generated on the side of the hob opposing the extraction opening and is directed toward the extraction opening.
According to a preferred embodiment, the at least one extractor apparatus is arranged to the rear of the hob. An extractor apparatus in which the extractor apparatus is spaced further apart from the user of the hob than from the hob is denoted as being arranged to the rear of the hob.
By means of the present invention, it is possible that at least one secondary air flow is discharged via the at least one blow-out opening so that the at least one secondary air flow is directed outwardly at least over the sides of the extraction body and/or upwards from the extraction body.
The secondary air flow directed outwardly and/or upwards over the sides can also be denoted as an air curtain or air film, and preferably is fed by more than one blow-out opening. The air curtain can represent a continuous curtain or can be formed from individual secondary air flows. The speed of the air in the latter case can vary slightly over the air curtain. The secondary air flow is directed outwardly at least over the sides of the extraction body. Thus the secondary air flow is directed in the width direction of the extractor apparatus and the hob. Due to this orientation of the secondary air flow, this secondary air flow is located transversely to the main direction of the primary air flow which is extracted from the hob in the direction of the extraction opening by the extraction of the blower. As a result, firstly the escape of vapors to the rear can be prevented since the secondary air flow can serve as an air curtain and shield the region above the hob to the rear. Secondly, due to the direction of the secondary air flow located transversely to the direction of flow of the primary air flow, at least one part of the primary air flow can be entrained by the secondary air flow. Due to reasons of continuity, further primary air flows through the entrained part of the primary air flow in the direction of the extraction opening and can be extracted into the extraction opening by the blower of the extractor apparatus. The secondary air flow can also be directed upwards or downwards at least in some portions, in addition to the outward orientation.
According to one embodiment, the secondary air flow is oriented such that it is located in a plane which is parallel to a plane in which the longitudinal extent of the extraction opening is located. According to the invention, however, it is also possible that the secondary air flow is oriented in a direction which is inclined to the front, in particular toward the hob. This inclination of the secondary air flow, however, is preferably small and, in particular, less than 90°, preferably less than 45°.
According to a preferred embodiment, the secondary air is discharged in a fan shape. In this case, a secondary air flow discharged from a blow-out opening can be fanned out. Alternatively, secondary air flows from a plurality of blow-out openings can form a fan shape together.
According to one embodiment, the secondary air flow flows upwards at least in the edge region of the upper face of the extraction body and the secondary air flow forms at least one vortex in the central region of the upper face of the extraction body. This can be achieved, in particular, by introducing blow-out openings in the side regions of the top wall of the extraction body. The center of the at least one vortex is located in front of the extraction body. Since the center of the vortex is located in front of the extraction body, firstly this can reliably prevent an escape of primary air upwards and secondly can deflect rising primary air in good time downwards in the direction of the extraction opening provided in the extraction side and thus assist the extraction. Preferably, two symmetrical vortexes are formed. In particular, in an air flow which is divided into two fans, in each case a vortex is preferably formed on the sides of the respective fan part which face one another, i.e. between which no secondary air flows upwards. The vortices are thus located in the central region of the width of the upper face of the extraction body. In this case, the two vortices can be separated from one another in the width direction of the extraction body or form a common vortex. The axis of the vortex or the vortices is parallel to the extraction side of the extraction body.
The speed of the secondary air flow is preferably greater than the speed of the primary air flow at the extraction opening.
According to one embodiment, the average exit speed of the secondary air at the blow-out opening can be set to range from 6 to 10 m/s with a volume flow of the secondary air of 70 to 150 m3/h. For example, an exit speed of the secondary air in the region can be set to range from 6 to 7 m/s with a volume flow ranging from 130 to 150 m3/h. Alternatively, it is also possible that a volume flow ranges from 70 to 130 m3/h. The exit speed can be higher by changing the geometry of the blow-out opening, in particular nozzles with a smaller outlet opening, or can be lower in nozzles with a larger outlet opening. The exit speed specifies an average exit speed, wherein the exit speed can be unevenly distributed over the blow-out opening or the nozzles provided therein. If low exit speeds are used, preferably a high volume flow is set in order to be able to achieve further advantages of the invention.
By means of the present invention, a targeted air guidance and an influence of the primary air can be carried out in a simple manner, for example by adapting the parameters of the extraction power of the blower, the size and position of the extraction opening and the volume flow, the speed and the direction of the secondary air flow. In particular, at least one vortex of the secondary air can be formed on the upper face of the extraction body, which firstly can prevent the primary air from escaping and flowing past the upper edge of the extraction body and which secondly assists the extraction of the primary air.
The present invention is described again hereinafter with reference to the accompanying figures. In the figures:
In
The extractor apparatus 2 has a housing 23, only a frame-shaped cover thereof being able to be seen in
The extraction body 22 can be held in the housing 23 so as to be retractable and extendable or fixed. In the embodiment in which the extraction body 22 is retractable and extendable, the state shown in
The extraction body 22 has an extraction side 220, a rear side 221 and three connecting walls 222. The connecting walls 222 represent a top wall 2220 and two side walls 2221. The extraction body 22 represents a hollow, upwardly closed body which can also be denoted as a channel. Extraction openings 20 are provided in the extraction side 220. Via the hollow extraction body 22 air can be extracted to the blower (not shown) located below the plane of the hob 3. In the embodiment shown, the extraction openings 20 are vertically running elongated slots. The extraction openings 20 are arranged adjacent to one another and extend from the bottom to above the center of the height of the extraction body 22.
Blow-out openings 21 are provided in the top wall 2220 and the side walls 2221. In the embodiment shown, the blow-out openings 21 are adjacent to the edge of the connecting wall 222 which adjoins the extraction side 220. In particular, blow-out openings 21 are provided in the side regions of the top wall 2220 and blow-out openings 21 are provided in the lower region of the side walls 2221.
It is indicated by the arrows A in
The extractor apparatus 2 also has a blower (not shown), air being extracted thereby into the extraction opening 20. Additionally, the extractor apparatus 2 can have an additional blower (not shown), air being conducted thereby to the at least one blow-out opening 21.
Secondary air is blown out from the blow-out openings 21. A boundary layer flow is generated between the primary air flow and the secondary fluid flow S. Due to air friction the primary fluid is entrained and deflected in a targeted manner in the desired direction to the extraction openings 20. Due to the mass movement of the primary fluid in the direction of the extraction body 22, a division of the primary fluid takes place in the direction of the extraction opening 20 and counter to the extraction opening 20 (following the secondary fluid). A continuous flow is thus formed. As a result, the primary fluid is increasingly deflected from the front and upper region of the hob in the direction of the extraction opening 20.
Additionally, an air curtain is formed by the secondary fluid flow S which significantly impedes an air flow from the region in front of the extraction body 22 to the region to the rear of the extraction body 22.
As emerges from
According to a further embodiment, not shown, the extraction opening 20 can represent one or more slot(s) running in the upper region of the extraction side 220 of the extraction body 22 in the horizontal direction, instead of the vertically running slots. In this embodiment, due to the secondary fluid flow S which is blown out through the blow-out openings 21, a fan which extends at least beyond the side edges of the extraction body 22 is also formed. Thus even in this embodiment an entrainment effect of the primary air flow P is generated by the secondary air flow S and the primary air flow P is reliably deflected toward the extraction opening 20 in the extraction body 22.
The speed of the secondary fluid flow is higher in the vicinity of the blow-out opening and is reduced at a greater distance from the blow-out opening 21.
The secondary air flow S in its front region entrains the mass of the primary air flow. For reasons of continuity, the mass of the primary fluid has to flow in.
A part of the extracted primary volume flow can come from the region to the rear of the hob and, in particular, to the rear of the extraction body 22. This volume flow is undesirable since, in the case of an extraction power which is too weak, it cannot downwardly entrain vapors which are produced on the hob and it takes up part of the total extraction power. According to the invention, the loss of flow can be limited by the secondary fluid entraining the mass of the primary fluid for reasons of continuity. As a result, in the remote upper region a flow tendency is already imposed on the primary fluid in the direction of the extraction opening 20 and thus the extraction body 22. Additionally, the secondary fluid functions as an air curtain which prevents the extraction of primary fluid from the rear of the extraction body 22.
The primary volume flow changed by the secondary volume flow counteracts the naturally rising thermal currents of the vapors and entrains these vapors in the direction of the extraction body 22 toward the extraction opening 20.
The present invention is not limited to the embodiments shown by way of example. In particular, the shape and arrangement of the blow-out openings, of the extraction body and of the extraction opening can differ from the embodiments shown.
In any case, however, the directed secondary air flow can deflect, in particular divert, the vapors such that these vapors pass in a targeted manner to the extraction openings. The exhaust air flow, i.e. the primary air flow, is extracted on the extraction side of the extraction body, and the directed secondary air flow is blown out on at least one of the connecting walls of the extraction body. By the targeted air guidance, the volume flow in the room above the hob can be regulated from the top, front and rear.
Preferably, therefore, an extractor apparatus, which can also be denoted as a downdraft extractor, is used with an integrated extraction opening, wherein at the same time a nozzle system for increasing the effective extraction power of the extractor apparatus can be accommodated in the extraction body. The extraction profile of the downdraft extractor is changed by the air which is preferably blown out upwards and to the sides, such that more air is extracted from the front and from the top. The extracted volume flow from the sides, i.e. from regions which are located adjacent to the hob, is correspondingly reduced. Due to the changed extraction profile the cooking fumes are transported more rapidly to the extractor apparatus so that these cooking fumes are extracted into the extractor apparatus before they are accelerated away too far from the extractor apparatus by their own thermal currents. The position of the blow-out openings, which can also be denoted as nozzles, is preferably provided at the side and at the top on the extraction body. The volume flow which is required by the extractor apparatus can range from 70 to 130 m3/h.
According to the invention, therefore, it is possible to reduce the required extraction power and thus the development of noise.
The present invention has a series of advantages. By means of the present invention, the vapor extraction behavior can be improved and additionally noise can be minimized and energy efficiency can be increased due to the lower conveying volume required for table ventilation systems. In particular, a very effective extraction, i.e. vapor capture rate, can be achieved on hobs which are located further away from the extraction region of the extraction opening, even in the case of tall pots. Current hob ventilation systems can extract vapors only over a defined distance. The distance of approximately 380 - 450 mm from the front cooking zone of a four-zone hob cannot be overcome by conventional conveying volumes, i.e. the vapors produced on the front cooking zone cannot be extracted. This problem does not occur in the present invention due to the targeted secondary air guidance. Additionally, extraction which is free from interference relative to cross flows is ensured. Moreover, a lower motor power of the blower is required and thereby the development of noise is minimized even with higher extraction power. Finally, by means of the present invention no additional cutouts and/or installation spaces are required around the hob since the blow-out openings are provided in the extraction body, and this extraction body and optionally an additional blower can be fitted in the extractor apparatus. Moreover, due to the provision of the blow-out openings in the extraction body, the outer shape of the extraction body can also be a continuous, in particular box, shape. As a result, the visual appearance and the cleanability is improved relative to extractor apparatuses in which a separate air channel is provided. The extractor apparatus according to the invention can also be used with a hob which is operated by gas.
