FIELDThe present invention relates to an exhaust hood having a chimney housing and a double-layered vapor-collecting canopy secured to the chimney housing.
BACKGROUNDGerman Publication DE 94 15 799 U1 describes an exhaust hood having a chimney housing featuring a double-layered vapor-collecting canopy secured thereto which, relative to the suction zone of the exhaust hood, includes an inner and an outer panel. The two panels each have a vapor-collecting surface, the outer panel extending substantially parallel to the vapor-collecting surface of the inner panel. The double panel so formed, and thus the vapor-collecting surface, can be extended to twice its width, as desired. To this end, the two panels are telescopingly supported on each other.
SUMMARYIt is an aspect of the present invention to provide an exhaust hood whose vapor-collecting canopy is not only used for conveyance of cooking vapors, but fulfills at least one additional function.
In an embodiment, the present invention provides an exhaust housing including a chimney housing and a double-layered vapor-collecting canopy secured to the chimney housing. The vapor-collecting canopy is near a suction zone of the exhaust hood and includes an inner panel and an outer panel. The inner panel has a vapor-collecting surface and the outer panel extending substantially parallel to the vapor-collecting surface. The inner panel and the outer panel are fixed relative to each other in a mounted position by at least one fastening arrangement. A portion of the inner panel and the outer panel are spaced apart in a direction perpendicular to the vapor-collecting surface forming an accommodation space for circuitry elements of the exhaust hood.
Aspects of the present invention will now be described by way of exemplary embodiments with reference to the following drawings, in which:
An advantage offered by the present invention is that the vapor-collecting canopy is not only dedicated to convey the cooking vapors rising from a cooktop, or the like, toward the suction zone of the exhaust hood, but also fulfills at least one additional function. Due to the double-layered construction of the vapor-collecting canopy, the space between the two layers can be used as an accommodation space for circuitry elements of the exhaust hood. This also allows the circuitry elements of the exhaust hood to be concealed between the two layers of the vapor-collecting canopy, so that they are invisible to the user.
The circuitry of the exhaust hood located in said space can be selected within wide suitable limits in terms of type, dimensions, and arrangement. The circuitry may be in the form of an electrical controller of the exhaust hood. By design, the vapor-collecting canopy is the lowermost part of an exhaust hood, and is therefore the easiest for the user to access. Therefore, arranging the electrical controller on the vapor-collecting canopy provides considerable advantages with respect to the use of the exhaust hood.
Signal transfer between the electrical controller and, for example, an exhaust hood fan mounted in the chimney housing, can be accomplished wirelessly. However, to make the exhaust hood immune to interference from other radio links, it is advantageous to use wired signal transmission. In order for the wired signal transmission not to disturb the overall aesthetic appearance of the exhaust hood, the accommodation space has at least one enlarged portion which is in the form of a wiring compartment and which extends to the connection area of the vapor-collecting canopy and the chimney housing.
However, the type, dimensions, and arrangement of the accommodation space can be selected within wide suitable limits. It is advantageous for the accommodation space to extend substantially over the entire overlap region, except for the attachment region where the two panels are joined together by a fastenings arrangement. In this manner, the accommodation space is maximized in a direction parallel to the vapor-collecting surface of the inner panel.
In an exemplary embodiment, the cross-sectional profile of the inner panel at the end of the vapor-collecting canopy facing away from the chimney housing has a portion which is set back toward the outer panel and which slopes downward toward the outer panel in any position of the vapor-collecting canopy. Thus, a condensate-collecting channel is created in a very simple way.
In another exemplary embodiment, the two panels each are provided in the attachment region with a three-dimensional profile extending toward the suction zone of the exhaust hood, the profiles of the two panels having corresponding shapes. This allows the two panels to be attached to each other without having to provide openings or additional fastening arrangements in the outer panel on the side facing away from the suction zone. Thus, first of all, the overall aesthetic appearance of the outer panel, and thus of the exhaust hood, is improved. Secondly, this makes it easier to attach cover panels to the outer panel on the side facing away from the suction zone, if desired.
The type, dimensions, and arrangement of the three-dimensional profiles of the two panels can be selected within wide suitable limits. In one advantageous embodiment, the profiles are each triangular in cross-section, because triangular cross-sections are structurally easy to fabricate.
In the two aforementioned exemplary embodiments, at least one of the profiles may be formed as an angularly bent portion of one of the two panels. Thus, the three-dimensional profile is very easy to manufacture and to attach to the associated panel.
It is possible for the double-layered vapor-collecting canopy to be formed in one piece, which is bent along at least one bending line to form the two panels. However, the double-layered vapor-collecting canopy may have a two-piece design, and the two separate panels have a further attachment region; the two attachment regions being located at opposite ends of the vapor-collecting canopy. Thus, two separate panels may be used to produce the double-layered vapor-collecting canopy.
The type, material, and arrangement of the fastening arrangements that attach the two panels to each other can be selected within wide suitable limits. For example, the two separate panels may be separably joined together in one of the attachment regions at least by at least one tongue-and-opening connection. In this manner, a structurally simple form of attachment is achieved in this attachment region.
In
Inner panel 12 has a vapor-collecting surface 12.1 and is spaced apart from outer panel 14 in a direction perpendicular to vapor-collecting surface 12.1, except for an attachment region symbolized by a circle 16 and a further attachment region symbolized by a circle 18, so that an accommodation space 20 for circuitry elements of the exhaust hood is formed between the two panels 12 and 14 of each vapor-collecting canopy 4.
An electrical controller 22 of the exhaust hood is disposed in accommodation space 20 of the vapor-collecting canopy 4 shown to the left, said electrical controller being connected in signal communication with the fan mounted in chimney housing 2 via an electrical cable. To this end, the narrower enlarged portion 20.1 of accommodation space 20 extends substantially over the entire overlap region of the two panels 12 and 14, and thus serves as a wiring compartment which extends to the area where vapor-collecting canopy 4 is connected to chimney housing 2.
Accommodation space 20 is also used here to receive fastening elements for fastening cover panels 6 to vapor-collecting canopy 4. The accommodation space 20 of the vapor-collecting canopy 4 shown to the right is used in an analogous manner.
The cross-sectional profile of inner panel 12 has a portion 12.2 which is set back toward outer panel 14 and which slopes downward toward outer panel 14 in any position of vapor-collecting canopy 4, so that any condensate running down the vapor-collecting surface 12.1 of inner panel 12 is reliably collected in the so-formed condensate-collecting channel and prevented from dripping onto the cooktop, or the like.
The two attachment regions 16, 18 mentioned earlier are located at opposite ends of vapor-collecting canopy 4, as can clearly be seen in
The attachment of the two panels 12, 14 in the further attachment region will now be described in more detail with reference to
The further attachment of the two panels 12 and 14 is described with reference to
When inner panel 12 is in the mounted position mentioned above, it abuts outer panel 14 in attachment region 16; see
Outer panel 14 has an angularly bent portion 14.4 formed at the upper end above profile 14.3. Vapor-collecting canopy 4 is engaged with said angularly bent portion to an edge of chimney housing 2 from above in order to provide the above-described hinged connection of vapor-collecting canopy 4 to chimney housing 2.
It is possible to use other suitable materials and fastening techniques with the present invention.
The present invention is not limited to island hoods, but may also be used in wall-mounted hoods or under-cabinet hoods.
In addition to the above-described exemplary embodiments where the accommodation space extends substantially over the entire overlap region of the two panels, the accommodation space may be located only in a portion of the vapor-collecting canopy; the dimensions, shape, and arrangement of the accommodation space is selectable within wide limits.
In addition to the described exemplary embodiment in which two vapor-collecting canopies are mounted to sides of a chimney housing, it is possible for alternative embodiments having only one vapor-collecting canopy or more than two vapor-collecting canopies.
The present invention is not limited to the exemplary embodiment described above.
