Description

[0001] The invention relates to an extractor hood or range hood according to the preamble of appended claim 1 in the form of a built-in appliance for installation in a wall cabinet.

[0002] When such extractor hoods are installed in overhead or wall cabinets, kitchen vapours or cooking fumes regularly settle on the front of the cabinets, which is unsatisfactory in terms of hygiene and aesthetics. In addition, the vapours can even penetrate into the cupboards or cabinets and affect the tableware and / or provisions stored therein.

[0003] The object of the invention is to remedy this situation and specify an extractor hood wherein said soiling effects are at least reduced.

[0004] The object is achieved by means of an extractor hood (or range hood) with the features defined in appended claim 1. Advantageous further developments thereof are defined in the subclaims.

[0005] According to the present invention, an extractor hood (or range hood) with additional air flows in the form of a built-in appliance for installation in a wall cabinet comprises a first fan for drawing in air, in particular air comprising cooking vapours or cooking fumes, from the surroundings. This first fan is operatively connected on the one hand (i.e., on an air intake or suction side thereof) to an extractor hood housing with an air intake opening. On the other hand (i.e., on a pressure or outpour side thereof) the first fan is connected to an exhaust air duct for the air drawn in, which can either be an evacuation duct (to the outside) or a recirculating duct. Said extractor hood is characterised by a baffle element that is moveable, either manually or automatically, between a folded-in position, in which it is located substantially inside or at least within a perimeter of the extractor hood housing, and a folded-out position, in which it is located outside the extractor hood housing on a front side of the extractor hood facing an operator, i.e., a person that uses the hood and who will usually be standing in front of it. Furthermore, in a horizontal direction, the baffle element, when folded out, is located in front of a forward side (or front) of the wall cabinet. Said baffle element accommodates at least one additional second fan or is in operative connection with such a fan. Furthermore, the baffle element has at least one first opening which is in operative connection with a pressure side (i.e., output side) of the second fan. A first air stream that is generated by the second fan is dischargeable through the first opening, said first air stream being orientated obliquely upwards in a direction towards the front of the wall cabinet when the baffle element is in the folded-out position.

[0006] In addition, optionally the baffle element has at least one second opening which is in operative connection with a pressure side of the second fan and a second air stream that is generated by the second fan is dischargeable through the second opening, said second air stream being orientated obliquely forward in a direction towards the operator (i.e., away from the cabinet) when the baffle element is in the folded-out position.

[0007] Said first air stream flows from the second fan to the external panels (or fronts) of the cabinets and serves to prevent the formation of condensation on the cabinets caused by steam from a hob or cooking device located below the hood.

[0008] Said second air stream, which is an optional feature, flows from the second fan towards the user (into the room / kitchen) in order to create an additional barrier against cooking vapours rising upwards, which can further help to reduce condensation.

[0009] In this way, the above-mentioned problems of prior art extractor hoods can be overcome effectively.

[0010] The following further embodiments of the extractor hood defined above have proved particularly useful: In a preferred further embodiment of the extractor hood in accordance with the invention, the hood is devised to comprise said second air stream that is generated by the second fan and is dischargeable through the second opening, said second air stream being orientated obliquely forward in a direction towards the operator (i.e., away from the cabinet) when the baffle element is in the folded-out position.

[0011] This has been explained in detail above and can help to achieve an enhanced performance of the proposed anti-condensation effect. However, said second air stream need not be present since the anti-condensation effect of the first air stream alone may already be sufficient in practice.

[0012] It should be noted that said at least one second opening need not be present if the extractor hood is not devised for producing said second air stream.

[0013] In a further embodiment of the extractor hood in accordance with the invention the baffle element is pivotable between said folded-in position and said folded-out position.

[0014] This provides an easy and ergonomic way of moving the baffle element between said two positions. However, the invention is not limited in this respect - a sliding or folding mechanism could be used instead, or any suitable combination of such mechanisms.

[0015] In a further embodiment of the extractor hood in accordance with the invention the baffle element accommodates one second fan, and the second fan is arranged centrally with respect to a longitudinal extension of the baffle element.

[0016] This is a very cost-efficient way of providing said first air stream and, if present, said second air stream in symmetric fashion with respect to the cabinet.

[0017] In a further embodiment of the extractor hood in accordance with the invention the baffle element has at least one third opening that is in operative connection with a suction side of the second fan, which third opening is located in a top side of the baffle element in the folded-out position thereof. Preferably, an air intake area of the second fan is located essentially at the same position as said third opening in a lateral direction of the hood, i.e., in a direction parallel to the cabinet front.

[0018] In this way, the air drawn in through said third opening is shielded from the cooking fumes by the baffle element.

[0019] In a further embodiment of the extractor hood in accordance with the invention the baffle element accommodates two second fans, and each of the second fans is arranged on one respective side of the baffle element.

[0020] Such a design can achieve improved performance due to enhanced first and, if present, second air streams.

[0021] In a further embodiment of the extractor hood in accordance with the invention the baffle element has at least two third openings each one of which is in operative connection with a suction side of a respective one of the second fans, which third openings are located in a top side of the baffle element in the folded-out position or which third openings are located in a respective end face of the baffle element. As stated before, the third openings are preferably located in the same lateral positions as the respective air intakes of the second fans.

[0022] In this way, the air drawn in through said third openings is not in direct contact with any cooking fumes.

[0023] In any case, the invention is not limited to a specific number of second fans.

[0024] In a further embodiment of the extractor hood in accordance with the invention the second fan or each of the second fans is / are devised as a centrifugal fan(s).

[0025] Applicant has found that the use of this type of fan is advantageous in terms of output flow, required construction space and incurred costs.

[0026] In a further embodiment of the extractor hood in accordance with the invention a rotation axis of an impeller of the second fan or each of the second fans is oriented essentially in a vertical direction when the baffle element is in the folded-out position.

[0027] In this way, the baffle element can take on a relatively flat configuration which is aesthetically and ergonomically preferred.

[0028] A further embodiment of the extractor hood in accordance with the invention comprises a control unit in operative connection with the second fan or with each of the second fans, which control unit is configured to switch on the second fan or each of the second fans when the first fan is activated.

[0029] In this way, condensation is automatically prevented whenever the hood is switched on, which usually implies that cooking fumes are or will also be produced.

[0030] In a further embodiment of the extractor hood in accordance with the invention the control unit is configured to vary an intensity of the first and, if present, second air streams and correlate it to an intake flow of the first fan, which is preferably linked to the different fan speeds that are selectable on the hood. Most preferably the control unit is devised to vary said intensity by means of a PWM (pulse-width modulation) control.

[0031] In this way, the achievable anti-condensation effect is linked to an activity level of the hood which is typically correlated to an amount of vapour produced during cooking.

[0032] A further embodiment of the extractor hood in accordance with the invention comprises a user interface in operative connection with the control unit. The user interface is configured to enable a first user operation to select a fan speed of the first fan that is linked to an intake flow of the first fan. The control unit can be further configured to enable a second user operation to manually switch on or off the second fan or each of the second fans.

[0033] In this way, the user can override the control unit and manually switch on or off the second fan or each of the second fans. It may also be possible for the user to manually select a level of said first and, if present, second air streams.

[0034] In a further embodiment of the extractor hood in accordance with the invention the hood comprises a septum that is configured to form, inside the baffle element, an air duct to guide air from the pressure side of the second fan or from a respective one of the second fans to said first opening and to said second opening.

[0035] Such a design constitutes a very simply, yet effective way of producing said first and, if present, second air streams.

[0036] In a further embodiment of the extractor hood in accordance with the invention the septum is configured to continuously reduce a cross-section of said air duct from the pressure side of the second fan or from a respective one of the second fans towards said first opening and said second opening.

[0037] This can compensate for any pressure losses inside the air duct and thus ensure an even flow of air through said first and second openings.

[0038] In a further embodiment of the extractor hood in accordance with the invention said first opening and said second opening, respectively, extends along said air duct, or there are a plurality of first openings and / or a plurality of second openings that are respectively arranged along said air duct.

[0039] In this way, the first air stream and / or the second air stream can be spread out more evenly and may cover a larger area.

[0040] In a further embodiment of the extractor hood in accordance with the invention the first opening is located in a top side of the baffle element in the folded-out position thereof and the second opening is located in a front portion of a bottom side of the baffle element in the folded-out position thereof, wherein said portion is preferably inclined with respect to a horizontal direction.

[0041] This helps to achieve the desired respective directions or orientations of the first and, if present, second air streams.

[0042] In a further embodiment of the extractor hood in accordance with the invention an air filter element is arranged on a pressure side of the second fan or each of the second fans. This filter element preferably comprises a grease filter and / or activated carbon and / or a HEPA air filter. Alternatively or additionally, said filter element preferably comprises a moisture / steam absorption element, e.g., of zeolite type.

[0043] In this way, a hygienic quality of said first and, if present, second air streams can be enhanced further, which is particularly useful for the second air stream that is oriented toward the user.

[0044] In a further embodiment of the extractor hood in accordance with the invention said first and / or second openings can have louvre-type angled slats in order to further enhance controlling a respective direction of the first and, if present, second air streams.

[0045] In the foregoing, the invention has been described in such a way that the first and, if present, second air streams are generated by at least one common (second) fan, i.e., an air output from the second fan(s) is somehow split in order to obtain said first and second air streams. However, the present invention shall also comprise embodiments in which there are separate second fans (i.e., at least two) for generating the first air stream and for generating the second air stream independently from one another. Preferably, these separate second fans can be operated conjointly or separately, which makes it possible to have only said first air stream or only said second air stream or to control a relative strength (or volume flow) thereof.

[0046] A similar effect can be obtained, in the context of the present invention, by providing an embodiment in which the first and second openings are (separately) controllable or adjustable, e.g., in terms of their size(s) and / or orientation(s).

[0047] Further features and advantages of the present invention will now be described with reference to the exemplary embodiments that are shown in the appended drawings. Figure 1 shows a sectional view of an extractor hood according to the invention; Figure 2 shows a perspective view of the extractor hood of Figure 1 in a first operational state; Figure 3 shows a perspective view of the extractor hood of Figure 1 in a second operational state; Figure 4 shows a perspective view of the extractor hood of Figure 1 in a third operational state; Figure 5 shows another perspective view of the extractor hood of Figure 4 in said third operational state; Figure 6 shows a perspective view of the baffle element for an extractor hood according to the invention; Figure 7 shows another perspective view of the baffle element for an extractor hood according to the invention; Figure 8 shows the extractor hood of Figure 1 together with the first air stream; Figure 9 shows the extractor hood of Figure 1 together with the second air stream; Figure 10 shows an exploded view of the baffle element of Figures 6 and 7; Figure 11 shows the air flow inside the baffle element of Figure 10; Figure 12 shows a sectional view of the baffle element in said third operational state of the extractor hood; Figure 13 shows the extractor hood of Figure 1 together with an alternative embodiment of the baffle element; Figure 14 shows an exploded view of the alternative embodiment of the baffle element; Figure 15 shows the air flow inside the baffle element of Figure 14; Figure 16 shows an alternative embodiment of the extractor hood according to the invention; and Figure 17 shows another alternative embodiment of the extractor hood according to the invention.

[0048] In all of the Figures, the same reference signs are used to indicated identical elements or elements having at least identical functions.

[0049] According to Figure 1 the extractor hood 1 is devised for installation in a wall cabinet 2, which is roughly illustrated by means of the dashed lines, where reference numeral 2a denotes a front or forward side of the wall cabinet, e.g. a (hatch) door. In the remaining drawings, the cabinet 2 is not shown for reason of clarity. The extractor hood 1 comprises a first fan 3 for drawing in air, in particular air comprising cooking vapours CV or cooking fumes, from the surroundings, i.e., from a space above a cooking hob 4 (dashed-dotted line). Said first fan 3 is operatively connected on the one hand, i.e., on a suction side thereof to an extractor hood housing 5 that defines an air intake opening 6 and on the other hand, i.e., on a pressure side thereof, to an exhaust air duct 7 for evacuation or recirculation the air drawn in (arrow A1). Reference numeral 8 denotes a grease filter.

[0050] The extractor hood further comprises a baffle element 9 that is moveable, either manually or automatically, between a folded-in position (not shown in Figure 1), in which it is located substantially inside the extractor hood housing 5, and a folded-out position, as can be seen in Figure 1, in which it is located outside the extractor hood housing 5 on a front side of the extractor hood 1 facing an operator 10, i.e., a person who uses / operates the extractor hood 1. In said folded-out position, the baffle element 9 is located, in a horizontal direction H, in front of said forward side 2a of the wall cabinet 2. In Figure 1, arrows H and V denote the horizontal and vertical direction, respectively.

[0051] The baffle element 9 accommodates at least one additional or second fan 11 and has at least one first opening and at least one second opening which are each in operative connection with a pressure side of the second fan 11, as will become apparent later. Preferably, there is one second fan 11 at each lateral end of the baffle element 9 (only one shown in Figure 1). Reference numeral 12 denotes a user interface in connection with a control unit 13 for controlling at least an operation of the baffle element 9, i.e., of said second fan 11, and preferably also of the entire extractor hood 1.

[0052] The second fan 11 is devised as a centrifugal fan, wherein a rotation axis of an impeller (not shown) of the second fan 11 or each of the second fans 11 is oriented essentially in a vertical direction V when the baffle element 9 is in its folded-out position.

[0053] As can be gathered from Figures 2 to 4, the baffle element 9 can be moved (swivelled) between said folded-in position (cf. Figure 2), in which it is located substantially inside the extractor hood housing 5, and a folded-out position (cf. Figure 4), in which it is located outside the extractor hood housing 5 on a front side of the extractor hood 1, as already shown in Figure 1. Figure 3 shows an intermediate position of the baffle element 9.

[0054] In particular in Figures 2 to 5, one can see a plurality of first openings 14 in a top side 9a of the baffle element 9 (wherein "top side" is defined according to the folded-out position shown, e.g., in Figure 4), wherein a first air stream AS1 (cf. Figure 4) generated by the second fan 11 (cf. Figure 1) is dischargeable from the baffle element 9 through the first openings 14, which can comprise louvres or slats to orient the first air stream AS1. Said first air stream AS1 is orientated obliquely upwards in a direction towards the front of the wall cabinet 2 (cf. Figure 1) when the baffle element 9 is in the folded-out position.

[0055] The first air stream AS1 flows from the second fan to the external panels of the cabinets to prevent the formation of condensation caused by steam from the hob below.

[0056] Preferably, the first openings 14 are arranged in a suitable pattern of rows and / or columns, as shown, the achieve the desired anti-condensation effect. However, in invention is not restricted to the pattern of openings 14 shown in the drawings. There could, e.g., be only one row of openings 14, and the individual openings 14 could be smaller than depicted.

[0057] Figure 5 further shows a plurality of second openings 15 that are located in a front portion 9b of a bottom side 9c of the baffle element 9 in the folded-out position, wherein said front portion 9b is inclined with respect to the horizontal direction H (cf. Figure 1). A second air stream AS2 generated by the second fan 11 (cf. Figure 1) is dischargeable from the baffle element 9 through the second openings 15, which can comprise louvres or slats to orient the second air stream AS2. Said second air stream AS2 is orientated obliquely forward in a direction towards the operator 10 (cf. Figure 1) when the baffle element 9 is in the folded-out position.

[0058] The second air stream AS2, which is optional, flows out of the second fan to create a barrier against cooking vapours rising upwards (cf. reference numeral CV in Figure 1).

[0059] Preferably, the second openings 15 are arranged in a suitable pattern of rows and / or columns, as shown, the achieve the desired barrier effect. However, in invention is not restricted to the pattern of openings 15 shown in the drawings. There could, e.g., be more than one row of openings 15, and the individual openings 15 could be smaller than depicted.

[0060] Figures 1 and 3-5 additionally show a plurality of third openings 16 that are arranged in a side end face 9d of the baffle element 9. Said third openings 16 are in direct fluid connection with a suction side of a respective second fan 11 (cf. Figure 1) and thus allow air to enter the baffle element 9 and be conveyed by the second fan 11. In the embodiment of Figures 1 to 5, there is one such second fan 11 on each lateral side of the baffle element 9.

[0061] Figures 6 and 7 show the baffle element 9 in isolated form. Reference numeral 17 denotes hinge parts that enable said swivelling motion of the baffle element 9 between its positions. The hinge parts 17 can be attached to the extractor hood housing 5 (cf. Figure 1).

[0062] Figure 8 once again illustrates the first air stream AS1 and also shows air streams AS3 that correspond to ambient air that is drawn in through said third openings 16 into the baffle element 9.

[0063] Figure 9 once again illustrates the second air stream AS2 and also shows air streams AS3 that correspond to ambient air that is drawn in through said third openings 16 into the baffle element 9.

[0064] Figure 10 shows the baffle element 9 in an exploded view. It comprises a top cover 9e that constitutes said top side 9a and has the first openings 14. It further comprises a bottom cover 9f that has the second openings (not visible) and the third openings 16. The top cover 9e has side apertures 9g in order not to block said third openings. Two centrifugal fans 11 (second fans) are located at opposite lateral ends of the baffle element 9 between top cover 9e and bottom cover 9f. A septum 9h defines two fan chambers 11a and guides the air flow AS4 (horizontal flow, cf. Figure 11) inside the baffle element 9 towards the openings 14, 15.

[0065] As can be gathered from Figure 11, which does not comprise the top cover, the septum 9h is configured to form, inside the baffle element 9, an air duct 9i to guide air from the pressure side of a respective one of the second fans 11 to said first openings 14 and to said second openings (not visible). Furthermore, the septum 9h is configured to continuously reduce a cross-section of said air duct 9i from the pressure side of a respective one of the second fans towards a centre of the baffle element 9 and thus towards said first opening and said second openings. This can help to ensure homogenous flow through said openings over their entire extension in the lateral direction.

[0066] Figure 12 is a sectional view that shows in detail various elements that were mentioned earlier. In particular, Figure 12 shows the louvres or canted structures 14a, 15a that are devised to orient the respective air streams, as explained earlier.

[0067] Figure 13 shows an alternative arrangement of the second fans 11 and an alternative configuration of the septum 9h inside baffle element 9 (top cover omitted). Further details of this embodiment will be shown in Figures 14 and 15.

[0068] According to Figures 13 to 15, the septum 9h is configured in straight fashion, and the fans 11 are oriented so that their respective output flows leave the fan chambers 11a through septum apertures 9h' towards the front where they are deflected sideways towards the centre of the baffle element 9 (perpendicular flow, cf. reference numeral AS4' in Figure 15).

[0069] Figure 14 further shows, in exemplary fashion, an air filter element 18 that is arranged on a pressure side (or, alternatively / additionally, on a suction side) of the second fan or each of the second fans 11, which filter element 18 preferably comprises a grease filter and / or activated carbon and / or a HEPA air filter, and / or which filter element 18 preferably comprises a moisture / steam absorption element, e.g., of zeolite type.

[0070] Figures 16 and 17 show further variants of the extractor hood 1 according to the invention that only vary in terms of the number of second fans and the respective air intake openings, i.e., said third openings.

[0071] According to Figure 16, there is only one second fan (not visible) which is located in a central portion of the baffle element 9. The third openings 16 are located just above the second fan in the top cover 9e of baffle element 9. There could also be only one second fan which is located in one of the end portions of the baffle element 9. In any case, the septum (cf. above) will be adapted geometrically to ensure transfer of air to the openings 14, 15 (cf. above).

[0072] According to Figure 17, there are two second fans as before (not visible) which are located in the end portions of the baffle element 9, as before. The third openings 16 are located just above the respective second fan in the top cover 9e of baffle element 9.

[0073] The second fans(s) need not be integrated into the baffle element 9, but could be located elsewhere, e.g., in the extractor hood housing 5, and would then be connected fluidically with the baffle element 9.

[0074] The second fan(s) can be switched on and / or controlled automatically together with the extractor hood (i.e., said first fan), preferably when the baffle element is folded out, e.g., via said user interface. It may also be possible to control the second and first fans independently and / or to override any automatic control manually, e.g., via said user interface.

[0075] If said first and second air streams are produced by different fans, it can be preferable to independently control a flow (volume and / or speed) thereof, e.g., via said user interface.
