Description

The present invention relates to a combination device with hob and extractor device.

In kitchens, it is known, instead of extractor hoods, which are arranged above a hob, for example, on the room wall or ceiling, to use so-called tray ventilators to aspirate fumes and vapors that arise during cooking. In the DE 10 2013 007 722 A1 For example, such a depression is described. In this case, a cooking steam inlet opening located in the cooking hob level is connected to a vacuum source via an exhaust air duct system. The dump ventilation is provided here as a separate device between two hobs or next to a hob. A disadvantage of this Muldenlüftung consists in the large space requirement, which is due to be provided exhaust duct system. In addition, in this case also the distance between the inlet opening and the vacuum source is large, so that increased demands on the vacuum source, which may in particular represent a suction fan, are provided.

Furthermore, from the WO 2012/146237 A1 a hob with central extraction of cooking fumes down known. In this hob one or more recesses are introduced in the area around the geometric centroid. Below the hob devices are provided for the withdrawal of kitchen fumes. The devices for extracting kitchen fumes preferably represent radial fans, which are attached to the underside of a hob housing and are sucked upwards via the air from the bottom of the cooker extractor chambers.

A disadvantage of this arrangement is that the requirements for the radial fans for generating a sufficient negative pressure are increased, in particular, since the flow of the cooking fumes must be deflected and the air flow in the device must be performed over a long distance.

The object of the present invention is thus to provide a combination device in which a simple and reliable manner with a preferably simple construction of the Combination device steam and vapors can be sucked from the space above a hob and still prevent the entry of contaminants in the fan of the extractor device.

The invention is based on the finding that this object can be achieved by providing in a combination device at least two recesses in the hob, that the distance between the recesses serves as a cover at least part of the fan of the extractor device and at the same time the way the air from the recesses to the blower must be low.

According to the invention the object is therefore achieved by a combination device comprising a hob with at least one cover plate and at least one heating element and arranged below the hob extractor device with a fan for extracting air from the space above the hob. The combination device is characterized in that in the hob at least two recesses are introduced and the at least two recesses are arranged offset horizontally to the fan arranged below the hob and the edge of the recesses in vertical projection on the underlying fan in the vicinity of or partially located on the edge of the air inlet opening of the fan.

The combination device according to the invention comprises a hob and a fume extraction device. In particular, these two components of the combination device as a mounting unit, that is structural unit configured. This means that the two components of the combination device are attached directly or indirectly to each other and can be introduced as a mounting unit, for example in a countertop. The combination device thus represents an assembled or preassembled unit, or a pre-assembled unit.

The hob according to the invention comprises at least one heating element and a cover plate. The cover plate covers the at least one heating element from above or the at least one heating element is applied to the cover plate from below. The size of the heating element or its effective radius, determines the size of the cooking zone or hob in the hob on the pots or other cooking vessels for Heating can be set up. The heating element can represent, for example, an induction module. Alternatively, however, the heating element may also be an electronic heating element in the form of a heating coil. Finally, it is also possible that at least one of the heating elements of the hob is a gas burner. In the latter embodiment, the cover plate does not cover the heating element, but has at the location of the heating element on a passage opening to the passage for the burner head.

The extractor device according to the invention comprises a fan and preferably in addition an air duct for guiding the air after exiting the fan from the combination device out.

According to the invention, at least two recesses are provided in the hob. The recesses are preferably introduced in the cover plate of the hob. It is also within the scope of the invention that the hob except the cover plate has a housing in which the heating elements are accommodated. In this embodiment, the at least two recesses are preferably in the top, which may be formed by the cover plate, introduced and in the bottom of the housing of the hob are arranged aligned with the recesses arranged openings.

The extractor device is arranged according to the invention below the hob. Arranged below the cooktop is an extractor device, in which at least part of the fan of the extractor device is located further down than the lowest point of the cooktop. In any case, the extractor device is arranged below the top of the hob. If the upper side of the cooktop, as preferred according to the invention, is formed by a cover plate, then the extractor device is arranged below the cover plate. The fan of the extractor device may for example be arranged between two heating elements of the hob or completely offset to the heating elements down.

Directional information, as above and below refer to the combination device in the assembled and mounted state, that is, in the state in which this is introduced, for example, in a horizontal worktop.

The air from the space above the hob and in particular fumes and vapors, which arise during cooking, are sucked off according to the invention via the at least two recesses of the hob. The recess in the hob is the intake of the combination device. As the intake of the combination device in this case the opening is referred to, enters through the air in the interior of the combination device. In the embodiment in which the recess of the hob, which is preferably in the plane of the top of the hob, in particular the top plate of the hob, the suction port, it is not necessary to provide further conduit elements, such as channels or pipes, which are opposite to the Extend the hob upwards. Thus, the structure of the combination device and its handling are simplified. In particular, pots or other cooking vessels can be moved substantially freely on the hob. Alternatively, however, it is also possible according to the invention that at least part of the combination device, for example a filter unit, extends slightly beyond the upper side of the hob.

According to the invention, the extractor device of the combination device has a fan, which is preferably a radial fan. The fan, which may also be referred to as fan or suction fan, preferably comprises a fan housing, which is designed for example as a spiral casing or screw housing and may also be referred to as a fan housing. In the blower housing, a fan is received, which is driven by a motor also included in the blower housing. The blower housing has an air inlet opening through which sucked air can reach the fan wheel. Furthermore, the fan housing has an air outlet opening, via which air can be discharged radially into a discharge channel or directly from the combination device. In a fan, which is a radial fan, the air inlet opening is preferably in the region of the axis of the fan wheel.

According to the invention, the recesses are offset horizontally relative to the fan arranged below the hob. This means that at least the air inlet opening of the fan in a vertical plan view of the hob is not completely in the surface of one of the recesses.

The recesses are in particular arranged so that the edge of the recesses lies in vertical projection on the fan below it or in the vicinity of the edge of the air inlet opening of the blower. Each of the at least two recesses is thus in a vertical projection on the plane of the air inlet opening in the vicinity of the air inlet opening but outside the air inlet opening. In the case where the edge of the recesses is in vertical projection on the fan below it near the air inlet opening of the blower, the edge of the recesses may, for example, extend between the outer radial edge of the blower and the air inlet opening. The edge of the recesses can thereby cut the outer radial edge of the housing in two places. However, the greater part of the area of the recesses lies outside the outer radial edge of the blower. In the case where the edge of the recesses in vertical projection on the fan below it lies partly on the edge of the air inlet opening of the fan, the two edges touch each other in a vertical projection in one point.

By the inventive arrangement of the recesses to the blower on the one hand, the way that the air has to travel from the recess to the air inlet opening of the blower, low. Nevertheless, due to the horizontal displacement of the recesses to the fan, the fan is at least partially protected against inspection by the user, and more importantly, against the entry of contaminants and liquids through the recesses in the fan. By virtue of the arrangement according to the invention, at least part of the air inlet opening of the fan of the extractor device is covered by the cover plate and in particular the distance or web between the recesses.

According to the invention, it is possible to provide one or more auxiliary fans, for example in the edge regions of the hob. With a suitable design of adjacent to the recesses fan but additional fans are not essential.

Since the hob and the extractor device according to the invention continue to be integrated in one device, and thus form a mounting unit, the assembly is simplified. In particular, hob and extractor device can be incorporated as a unit in a countertop or other surface and optionally removed. Furthermore, the required height is reduced by the integration of the two components in a combination device, since the components of the components aligned with each other can be provided in the combination device. The overall height of the combination device according to the invention may be, for example, 15 to 30 cm and preferably 20 cm. Thus, the combination device can be easily integrated into a kitchen.

According to one embodiment, the fan is arranged in the combination device, that the air inlet opening of the fan and in particular of the fan housing faces the hob. Facing the hob, an air inlet opening is designated, via which air can be sucked from above into the blower and thus the blower housing. In particular, facing the cooktop thus an air inlet opening is referred to, which is at the top of the fan and thus the blower housing. Preferably, the air inlet opening is parallel to the hob and in particular to a cover plate of the hob. In this case, the air inlet opening thus lies in the horizontal and is directed upward. However, an inclined relative to the horizontal air inlet opening at the top of the fan can be regarded as the hob. However, the angle of inclination is preferably less than 90 ° and more preferably less than 45 °.

By this orientation of the air inlet opening of the blower, which is arranged adjacent to the recesses, the air can be sucked in a simple manner by the blower. In particular, only a slight deflection of the air flow is required. Thus, the requirements for the performance of the fan are lowered. In addition, the size of the fan can be selected regardless of the size of the heating elements or the housing of the hob by the orientation of the fan with an upwardly facing air inlet opening. The blower may be attached to the side of the blower housing that faces the air inlet opening. In contrast to the prior art, in which the blower with the air inlet opening opposite side attached to the underside of the housing of the heating element, in the embodiment of the combination device according to the invention with upwardly directed air inlet opening thus a larger blower can be used. The blower can in this case be attached, for example, to the bottom of a device housing of the combination device, the area of which generally corresponds to the surface of the hob. In addition, according to the invention, it is also possible for the fan to be fastened on the same side in which the air inlet opening is provided, in a region around the air inlet opening, on the hob, in particular on the underside of the hob and in particular an underside of a hob housing. Also, in this embodiment, since the air inlet opening of the fan facing the hob, that is directed upward, the size of the fan can be made large and the fan can be fixed, for example, under two heating elements, which lie on opposite sides of the recess. A thus possible larger blower can produce the desired air flow even at low speed and the noise of the fan is therefore also reduced.

According to one embodiment, the edge of the at least two recesses in the vertical projection of the recesses on the plane of the fan is partially located on the outer edge of the blower housing of the blower. The blower housing is preferably a volute, which may also be referred to as a screw housing. The outer edge of the blower housing is in this case the radially outer edge. by having the at least two recesses in vertical projection on the plane of the fan partially on this edge, the recesses may be arranged so that they are arranged completely offset horizontally to the housing. In this case, the edge of one of the recesses and the edge of the housing cut only in one point. In such an arrangement, the horizontal distance between the recesses and the air inlet opening is so large that an immediate entry of contaminants and liquids can be prevented and yet the suction into the air inlet opening can be done in a reliable manner.

According to one embodiment, the fan is arranged centrally in the combination device. In this case, a blower which is located in the middle in the width direction of the combination device and in the depth direction of the combination device is referred to as centrally arranged. The fan is thus in the center of area of a rectangular Combination device. The at least two recesses are offset in a centrally arranged fan to the center of the combination device placed in the hob. As a result of this arrangement of the recesses, the recesses serving as intake openings are located outside the middle of the surface of the combination device. As a result, the extraction of air from above the hob is improved. In particular, the recesses can be arranged between heating elements of the hob and thus lie in the vicinity of the cooking zone formed by the respective heating element.

According to one embodiment, the fan is arranged in the center of the surface of the combination device and a recess is in a vertical projection on the plane of the blower to the fan forward offset and another recess is offset in a vertical projection on the plane of the fan to the rear. This embodiment is advantageous, since thereby the recesses lie only in the middle of the width direction of the combination device and in particular the cover plate. Thus, a heating element extending over the entire depth of the combination device and in particular over the entire depth of the hob can be arranged on the left and on the right side of the recesses. Even if left and right of the recesses in each case two in the depth direction successively arranged heating elements are provided, at least the cover plate to the left and right of the recesses may be continuous and thus a shift of Gargutgefäßen be possible in these areas. In addition, the recesses between the right and left heating elements are introduced by the arrangement of a recess in front of and a recess behind the centrally located fan and it can thus be reliably sucked air from the left and right cooking zones.

The recesses according to the invention, for example, a round or square shape, in particular slot shape, on. If a rectangular slot shape is selected, then the longitudinal direction of the recess is preferably in the depth direction of the combination device and in particular the cover plate of the hob.

According to a preferred embodiment, in each case a filter unit with at least one filter element is releasably attached to the at least two recesses. This allows the entering into the combination device air of fats and other liquids and impurities are released. The filter element may be formed in the combination device according to the invention as a filter plate or filter mat or a hollow body of filter material. The filter material may for example be expanded metal or braided or knitted metal threads. In particular, braided or knitted metal threads can be used in the combination device according to the invention, since in this the suction takes place from the surface of the combination device downwards and the filter element lies in the plane of the recesses or below the plane of the recesses. Falling out of individual filaments, which may occur in such filter material, is harmless, as they fall into the combination device and thus pose no health risk, as is the case with hoods arranged above the cooktop.

According to one embodiment, the filter element is a hollow body. According to the invention, hollow body is understood to mean a body which consists of an outer wall, which may also be referred to as outer surface or lateral surface, and which is open at least on the upper side. The hollow body may also be referred to as a pipe section or profile piece, wherein the cross section of the pipe section or profile piece may be, for example, round or polygonal, in particular quadrangular. The hollow body may thus represent a piece of pipe with a round or rectangular cross section. In particular, with a rectangular cross-section, it is possible that, for example, only two opposite sides of the filter element consist of filter material and the other two sides consist of a metal plate or plastic plate. The advantage of using a filter element embodied as a hollow body is, in particular, that the available filter area is enlarged compared to a flat filter element. In particular, in the combination device according to the invention, in which the recesses are arranged offset horizontally to the fan, there is a certain height below the recess, in which the filter element can protrude. At a minimum, the distance between the top of a fan and the bottom of the cover plate may be used for the filter element.

According to one embodiment, the filter element is arranged vertically in the filter unit. However, it is also within the scope of the invention to use the filter element inclined in the filter unit. This can be, for example, down tapered hollow body can be used as a filter element. By means of a vertical or possibly inclined arrangement of the filter element or elements, the advantage can be achieved that liquids which are deposited in the filter element can run downwards in the filter element. Thus, dripping of liquids from the filter element can be prevented. In addition, in the case of the combination device according to the invention, the vertical orientation of the filter element is advantageous also for the reason that the edge of the recess into which the filter unit is introduced lies in the vicinity of the air inlet opening of the blower. Thus, the negative pressure acting on the filter element is higher than that of a more widely spaced filter element and the cleaning and suction of the air can be improved thereby.

According to a preferred embodiment, the filter unit has a collection area for liquids, which is preferably formed by a bottom of the filter unit. The collecting area is preferably formed by a trough or gutter. By the filter unit having a collecting area, on the one hand, the liquid emerging from the filter element can be collected. Since the filter unit is releasably secured in the recess of the cover plate, also the collection area can also be removed from the recess and thus released from the combination device. As a result, the handling of the combination device is simplified because the user can clean both the filter element of the filter unit and the collection area in a simple manner. By preferably forming the collection area through the bottom of the filter unit, further advantages can be achieved. On the one hand, a reliable run-in of liquids from the filter element into the collecting area can be ensured. In particular, in an embodiment in which the collecting area is formed by the bottom and has a trough shape, that is, the filter unit down closes, in a vertically oriented filter element, the collecting area directly for collecting liquids that enter through the recess. The prevention of the ingress of liquids into the fan of the combination device is ensured according to the invention, on the one hand, that the distance between the two recesses serves as a cover of the air inlet opening. By additionally providing a collecting area in a filter unit introduced into the recesses, it is also possible to prevent the entry of liquids via the recesses into the air inlet opening. According to a further embodiment, the combination device has an overflow container for liquids from the collecting area. In this case, a container is referred to as the overflow container, which container lies at least partially under the filter element and in particular the collecting region of the filter element. In particular, the overflow tank is located below the part of the collecting area from which liquids can escape. If the filter element is a vertically oriented filter element and the filter unit has a base which serves as a collecting region, then the overflow container will preferably lie completely below the filter unit and in particular the collecting area. In such an embodiment, namely, upon reaching a level in the collecting area, which corresponds to the lower edge of the vertically oriented filter element, liquid can pass through the filter element to the outside. In a completely arranged under the filter unit overflow container, the thus emerging liquid can reliably enter the overflow tank. The overflow container may for example have a trough shape.

The overflow container according to the invention represents a component which is installed in the combination device and, for example, in a device housing of the combination device. It is thus not the bottom of a device housing used as an overflow container. By the overflow container is a separate component, this can be installed at a height in the combination device, which is offset up to the bottom of the combination device. Since preferably the fan on the bottom of the combination device, for example, on the bottom of a device housing, the fan of the extractor device is mounted, and the overflow container is offset to this floor up, an entry of liquids into the fan can be reliably prevented.

According to one embodiment, the overflow container is fixedly mounted in the combination device. This means that the overflow container is not detachable from the combination device compared to the filter unit. Thereby, a correct orientation of the overflow container to the recess into which the filter unit is inserted and to the blower and in particular the air inlet opening of the blower when assembling the combination device can be set and accidental incorrect positioning of the overflow container by the user can be prevented. The overflow tank is preferably accessible through the recess in the cover plate of the hob and can be emptied and cleaned by the user hereby. Alternatively, a closable opening can be provided on the underside of the overflow container, via which the overflow container can be emptied.

The provision of an overflow container is in the inventive arrangement of the recesses to the blower of particular importance. The recesses are provided in the vicinity of the air inlet opening in order to ensure efficient extraction of air through the recesses to the air inlet opening. Due to the proximity of the recesses to the air inlet opening but also the risk of ingress of liquids in the fan is increased. In particular, in situations where large amounts of liquids on the recesses in the combination device occur, for example, when overcooking of liquid food, the provision of an overflow container is therefore required.

The hob and the extractor device according to the invention can be attached directly or indirectly to one another. In an immediate attachment, for example, the side of the fan of the extractor device, in which the air inlet opening is provided, be attached to the hob, for example on the underside of a hob housing.

An indirect attachment of the hob and the extractor device can be realized for example by a device housing. In this embodiment, the hob and the extractor device are accommodated in a common device housing. In this case, the device housing may in particular have a trough shape. To the top of the device housing is completed by the hob and in particular by the cover plate of the hob. In the device housing also an air outlet is introduced. The air outlet may be provided for example on the back of the device housing. Alternatively, it is also possible that the air outlet is placed on one of the side walls of the device housing or is introduced into the bottom of the device housing. In the device housing, at least the extractor device of the combination device is preferably attached. The hob can be introduced either from above into the device housing and, for example, with the cover plate on the The upper edge of the walls of the device housing rest. Alternatively or additionally, however, the heating elements of the hob can also be fastened, for example, to the inside of the appliance housing, or held.

By the extractor device and the hob are connected directly or indirectly in the combination device, both the assembly and the assembly of the combination device is simplified. When assembling the relative position between the components of the extractor device and the hob is already given by the device housing. For example, the orientation of the recesses can be ensured with the blower. During assembly, in particular the introduction into a worktop, the introduced in the device housing components of the extractor device and the hob or the directly attached fume extractor and hob can be introduced in a mounting step in a countertop or other surface. If the cover plate is a separate component of the heating elements of the hob, this can optionally be applied later.

According to a preferred embodiment, the hob and the extractor device of the combination device on a common electrical network connection. This power supply can be provided for example on the device housing and supply the electrical components of the extractor device and the hob with voltage. Furthermore, the control of the components of the extractor device and the hob can be done by a common control device. For example, the extractor device can be actuated depending on the operating state of the hob.

In the in FIG. 1 In the embodiment shown, a recess 104 is projected in vertical projection onto the plane of the fan 110 to the fan 110 to the front and the second recess 104 in vertical projection on the plane of the blower 110 to the fan 110 to the rear. In the embodiment shown, two heating elements 101 are provided, each extending in the depth direction of the hob 10. Between the two heating elements 101, a region is formed in which only the cover plate 103 of the hob 10 is present, that is, in which no heating element 101 is disposed under the cover plate 103. In this middle region, the recesses 104 are introduced. The recesses 104 thus lie between the two heating elements 101, which ensures a reliable suction of air from Gargutgefäßen (not shown) which are placed on the right cooking zone 102 and Gargutgefäßen (not shown) which are placed on the left cooking zone 102.

In FIG. 2 a further embodiment of a combination device 1 according to the invention is shown. This second embodiment differs from the first embodiment in that instead of a central fan 110, two blowers 110 are provided. The one fan 110 is in this case provided in the front region of the combination device 1 in the middle of the width of the combination device 1. The second fan 110 is provided in the rear region of the combination device 1 in the middle of the width of the combination device 1. Also in the second embodiment, two recesses 104 are inserted into the cover plate 103 of the hob 10. However, the recesses 104 are square in this embodiment, in contrast to the round recesses 104 of the first embodiment. However, it is also within the scope of the invention that, for example, in the first embodiment, quadrilateral recesses 104 or in the second embodiment round recesses 104 are provided. The recesses 104 in the second embodiment also adjoin the radially outer edge of the blower 110. Here, the rear recess 104 adjoins the rear fan 110 and the front recess 104 to the front fan 110 at.

The lateral boundaries of the air outlet duct 17 and the air duct 16 may be formed by walls or channel members (not shown) in the apparatus housing 14.

As an alternative to the embodiment shown, in which the hob 10 and the extractor device 11 are accommodated in a device housing 14, it is According to the invention also possible to carry out the combination device 1 without device housing 14. In such an embodiment, then, for example, the top of the fan 110, that is, the side in which the air inlet opening 115 is provided, in the area which is outside the air inlet opening 115, on the underside of a hob housing (not shown) may be attached. The air duct 16 is hereby formed example meadow by a channel element.

In the recesses 104 filter units 12 are introduced. Each of the filter units 12 comprises in the illustrated embodiment a filter element 120 which forms a hollow body with a round cross-section. The filter element 120 is vertically aligned, that is, the lateral surface of the round filter element 120 is in the vertical. The filter unit 12 further has a filter holder 121, via which the filter element 120 is held on the recess 104. The filter unit 12 also has a bottom 123. The bottom 123 has a trough or pot shape. As a result, a collection area 122 for liquids is created in the bottom 123. The filter element 120 rests on the bottom 123 of the filter unit 12. Below the filter unit 12, an overflow container 13 is fixedly mounted in the combination device 1. The overflow container 13 is arranged so that it projects beyond the bottom 123 of the filter unit 12 to all sides. The bottom of the overflow container 13 is arranged in the illustrated embodiment at a height which is below the top of the blower housing 113 but above the bottom 14 of the device housing 14. The overflow container 13 may constitute a continuous container extending over both recesses 104. In this case, however, an opening is provided in the region of the air inlet opening 115 of the blower housing 113. However, it is also within the scope of the invention that a separate overflow container 13 is provided for each recess 104 and thus for each filter unit 12.

The function of the combination device 1 is described again.

In the fan 110, a fan 112 is driven by the motor 111. As a result, air is sucked into the blower housing 113 via the air inlet opening 115 of the blower housing 113 facing upwards and thus towards the hob 10. The air is hereby sucked from above the hob 10 through the recesses 104 in the combination device 1. In this case, the sucked air stream L passes through the filter element 120. The air thus cleaned is passed through an air outlet opening (not shown). blown out of the blower housing 113 and passes from there either indirectly via an outlet channel (not shown) or directly to an air outlet 18 of the device housing 14. From there, the air in the environment or in the room in which the combination device 1 is operated, are delivered ,

Liquids, such as water and grease, which are deposited on the filter element 120 from the air may run down the filter element 120. Since the filter element 120 is provided on a bottom 123 of the filter unit 12, which forms a collection area 122, the liquid can be collected there and does not enter the blower 110. If either a large amount of liquid is deposited on the filter or fluid overflows Recesses 104 in large quantities in the combination device 1, for example, when overcooking food, so first fills the collection area 122 of the filter unit 12. Once the liquid level has reached a level in the collecting area 122, which corresponds to the lower edge of the filter element 120, so runs Alternatively, it is also possible for one or more overflow openings (not shown) to be provided in the collecting area 122, that is to say in the floor, via which the liquid flows into the overflow container 13 can.

Although the invention has been described essentially with reference to vertically extending filter elements 120, it will be understood that other filter elements 120, such as inclined filter elements, may be used.

With the present invention, a combination device is provided, which can also be referred to as an integrated hood in a hotplate.

Preferably, in this case, two recesses, which may also be referred to as openings or wells, arranged front and rear of the air inlet opening of the fan, so that the fan is not visible to the user.

An advantage of the invention is that the entry of liquids into a fan can be reliably prevented and yet a reliable extraction of fumes and vapors can take place. In the invention, it is possible to use only one blower use, which can be made larger and turns slower. As a result, the noise is reduced.
