Description

The present invention relates to a set of an extractor hood and at least two spacer components for mounting the extractor hood in a kitchen.

Extractor hoods for extracting cooking and other kitchen fumes over a stove or cooking surface are mounted free-standing or between or in kitchen carcass elements. The following is an assembly between kitchen corpus walls the speech, which means both the assembly between the outer walls of a kitchen carcass element, ie an assembly in this kitchen carcass element, including the assembly between two kitchen carcass elements, ie their respective next walls.

Hoods are used in a conventional manner in a matching kitchen cabinet, the hood is tuned to the carcass width or vice versa or the hood is inserted between suitably mounted kitchen carcass elements. It is known to create a free space to be able to mount a hood with too narrow a width laterally on kitchen carcass walls or a hood with a planned for mounting but too narrow component, such as fan box, despite the too small width between kitchen carcass walls to assemble can. Conventionally, one would have selected in such cases either matching cooker hoods or other arrangements of kitchen carcass elements selected or mounted the hood "backwards" on the wall of the room. The closest prior art is the document DE 199 06 322 A1 is from which a connection of a mounting rail with a side wall of the cabinet part via a spacer block is known. The hood is then pushed from front to back on the mounting rails. Mounts on laterally adjacent kitchen cabinet walls are on the one hand common, so that the assembly staff is used to it and for hoods typical mounting systems exist and are controlled. On the other hand, the results are usually more stable.

It is also known to provide a spacer member that is sized in width so that it is the remaining space between the Extractor hood or its intended for installation component and the candidate kitchen body wall fills. Such spacer components are known and also form a certain additional expense because they have to be specially manufactured, supplied and assembled. However, they increase the flexibility in the assembly of cooker hoods so clearly that these disadvantages can be accepted.

The invention is based on the technical problem of providing improved mounting options for a cooker hood in a kitchen.

The object is solved by the features of claim 1.

A preferred application of the invention relates to cooker hoods, which include different widths of components. In particular, in many cases, a lower grease filter assembly, which thus contains the usual grease filters, wider than a mounted above other assembly, such as a food chimney or a fan box of a drawer cooker hood (also referred to as "flat screen hood"). Then, the invention provides to bridge the width difference by two or a plurality of distance component / s according to the invention. This allows the cooker hood to be mounted between kitchen cabinet walls that are spaced apart from the grease filter assembly. This is of particular interest if, as explained below, there are series of cooker hoods in which the width deviations between the grease filter assembly and the overlying unit of the extractor fan vary in size. Then, by appropriate sets of spacer components uniform requirements be created for the assembly.

The preferred application in terms of the design of the hood is the so-called. Drawer type, in which the mentioned grease filter assembly is a so-called. Drawer unit which contains a movable part that can be pulled drawer-like by the user by hand or by motor. Thus, an increased depth for the trigger and a better coverage of the hob can be created. In contrast to so-called food, in which the width differences between the food chimney and the grease filter assembly are optically quite deliberate in many cases and remain visible, drawer extractor hoods are usually installed in or between kitchen carcass elements (and in the latter case blinded), in which case a lateral mounting on kitchen corpus walls is of particular interest. In particular, the use of spacer components in conjunction with a lateral mounting can cause a comparatively particularly stable assembly and even stabilization of the extractor hood itself.

According to the invention, two identical spacer components are used per fume hood, one on each side, as the embodiment shows.

These spacers may be in a particular embodiment to U-profile sheets, preferably Have mounting plates for the kitchen cabinet wall. They may also preferably have a fastening device for a protruding in width drawer assembly, which is thus arranged during assembly under the spacer member. This creates additional stabilization. In question come in particular screw. It is further preferred that a part of the U-profile sheet, for example one of the two legs, is substantially flush with a front face of the extractor hood, in particular of the fan box. This can have optical reasons if glare is omitted. On the other hand, the spacer components should not be introduced close to the wall for reasons of stability, so that because of the relative to the drawer unit usually recessed construction depth of the fan box such flush termination provides a stable installation. At the same time, the volume remaining in front of the fan box and coming into consideration for storage space is not restricted.

For connection between the hood, such as the fan box, and the distance components according to the invention a locking connection is provided according to the invention with an undercut edge and a spring latching device. Preferably, the undercut edge on an element of the spacer member, such as a bolted plastic block, and is the spring latching device in the corresponding Wall of the hood or the fan box provided. Thus, the hood can be fixed in a particularly simple and fast manner latching between the kitchen carcass walls and optionally additionally braced with screws.

In addition, a screw connection can be provided for connection.

The bridged by the spacer member width according to the invention should have a significant size, so that the benefits of the invention are relevant at all. In particular, widths of at least 10% of the corresponding extractor hood width are preferred.

The invention is directed in one embodiment also to a set of a plurality of drawer extractor hoods, each with a fan box and each one attached to the bottom of the fan box drawer unit in which the hoods equipped with the same fan boxes and width divergent drawer units are and are further combined as described with matching spacer components for mounting.

The invention is based on the fact that vapor extractor hoods of the described design already exist in the market of different widths. These designs are built into kitchen cabinets sized for size and are often matched in width to the width of the oven or hob below. The width hereby means the horizontal width extension from the perspective of the user, who stands in front of the stove or the hob and the extractor hood operated and used. For example, widths of 60 cm, 70 cm or 90 cm are common.

The basic idea now is to use a system of cooker hoods, in which only the drawer unit is adapted to the particular desired width or is selected to match this width and the fan box to be used remains the same. So a fan box is used, which can be used with different widths of drawer units. Preferably, the fan box is adapted to the smallest occurring drawer unit width in the system, for example 60 cm, and substantially as wide as this.

Then the same fan box can be used with respect to actually overly wide drawer units and thus sucks from laterally projecting areas of the drawer units also from. This does not lead to technically significant problems, because, for example, by extending the movable part of the drawer unit also one, but in depth, beyond the fan box protruding part is generated, which is usually also provided with filter surface. Incidentally, the inventors have recognized that, for example, with a 90 cm width of the drawer assembly compared to a conventional manner here about 90 cm wide fan box without doubt existing limitations, however, in relation to the advantages of the invention accepted can be.

With the invention, however, significant cost advantages are achieved and also achieved a simplified storage and production organization by fan cases can be used in significantly larger numbers without significant deviations in construction and only in the design of the drawer unit adjustments to the width must be made. Even in the drawer unit largely standardized parts can be used. In particular, a frame part of the drawer unit that serves for mounting the same on the fan box and generally has substantially the same width as the fan box, be identical in all the extractor hoods occurring in the series. The same can, for example, for covers of the moving part of the drawer unit including controls u. Ä. be valid. In the area in which the drawer unit protrudes laterally beyond the fan box, elements of different width, such as cover profiles of different widths and guide profiles for the moving part, can then be used. Further, the grease filter modules may be adapted with expanded metal grease filters or other reusable grease filters or the corresponding disposable grease holders, the light bars used and other components that are usefully widened with the wider drawer assembly. The Drawer unit is thus constructed from a parts kit, which can also be standardized to a certain extent.

When installing those cooker hoods from the series, which protrude laterally across the width of the fan box, then preferably kitchen carcass formats can be used, which correspond substantially to the width of the drawer unit. This i. d. R. already optical reasons, although the invention of course also refers to cases in which the drawer unit protrudes laterally over the kitchen cabinet. However, if the kitchen body is significantly wider than the fan box, so the spacer components described can be used with which a lateral mounting of the narrower relative to the kitchen body fan boxes on the walls of the kitchen carcass can be done.

In the following, an embodiment of the invention is explained in more detail, wherein the individual features may be essential to the invention in other combinations.

Fig. 1, 2 and 3 show drawer extractor hoods with different widths drawer units.

Fig. 4 shows part of the cooker hood Fig. 1 with a spacer component according to the invention.

Fig. 5 shows the hood from the Fig. 1 and 4 with two in it mounted distance components.

Fig. 1 shows a hood 1 of the building type with an upper fan box 2 and a drawer assembly mounted thereunder 3. The technical details of the fan box 2 are conventional in nature or not relevant to the present invention. It contains blower fans for drawing in kitchen fumes through the drawer unit 3 and in the upper area of the fan box 2 in FIG Fig. 1 identifiable but not numbered connections for an exhaust duct and an electrical power supply.

Below is the drawer unit 3, which is essentially a flat plate-like unit with over the fan box 2 clearly outgoing width. In the present case, the fan box 2 is about 54 cm wide, the drawer unit 3, however, 90 cm wide. So it stands on the right and the left side about 18 cm above. The fan box 2 has in the lower part in consequence of in Fig. 1 recognizable level a slightly greater depth than in the upper area. The drawer unit 3 corresponds to this greater depth, thus closing in the depth dimension substantially flush with the fan box 2 from. A part of the drawer unit 3 can be drawer style pull forward, the perspective of the Fig. 1 corresponds to the perspective of the user.

The FIGS. 2 and 3 show a cooker hood 4 with The differences between the extractor hoods 1, 4 and 6 are limited to the drawer units 3, 5 and 7. These are different widths, namely 70 cm wide in the case of drawers. Die Schubladen-Baueinheit 5 bzw. Construction unit 5 and 60 cm wide in the case of the drawer unit 7. The side projections are therefore 8 cm and 3 cm.

The extractor hood 6 with the drawer unit 7, the side hardly protrudes beyond the fan box 2, can be considered as far as conventional - apart from structural details - as conventional. It is common in drawers-hoods to align the fan box and the drawer unit in about the same width and also install in a suitably sized kitchen carcass. In the manufacturing method according to the invention, a same fan box 2 is now also used for wider drawer units 5 and 3, which consequently protrude laterally, which was conventionally provided for larger losses in the wide drawer Baueinnicht due to certain losses in the flow area and larger building restrictions in the fan unit , However, the invention assumes that the technical performance of the fan box 2 is sufficient and that the disadvantages compared to the considerable cost advantages of a "modular" Construction of an extractor hood series with the same fan box 2 can be compensated by far. In particular, it is possible to design and produce at a more costly location elsewhere or to offer a particularly competitively priced product.

Fig. 4 shows the hood 1 Fig. 1 and over the laterally projecting parts of the drawer unit 3 separately drawn inventive spacer 8. Fig. 5 shows the same extractor hood 1 with mounted distance components 8. The two spacer elements 8 are equal to each other, but could for example be the same width mirror image of each other, and serve to substantially compensate for the width difference occurring through the projection of the drawer unit 3. Fig. 5 shows that this width difference is not completely bridged, because in this type of hood usually the drawer unit 3 protrudes about 3 cm below adjacent Küchenkorpusse. In this example, the width of the spacer member 8 is about 15 cm and the supernatant of the drawer assembly 3 is about 18 cm.

It can also be seen that the spacer elements 8 consists of a substantially U-shaped profile sheet with slightly divergently opening legs, being provided at the leg ends in the upper part Anschraublaschen for attachment to a Küchenkorpuswand with screw holes. These mounting plates are in Fig. 4 numbered 9.

The U-profile sheet is in the lower region by a bent from one leg and guided to the other leg sheet metal part 10 ( Fig. 5 ), which serves as a mounting plate for the drawer unit 3 and contains screw holes, not shown. As far as described so far, the spacer element 8 is simple stamped and bent sheet steel components.

Further, at the base of the U-profile corresponding fan case side surface of the spacer members 8 in the lower part of a flat plastic plate 11 is screwed, which has an upwardly facing undercut edge, which is not clearly visible in the Fig. Fig. 4 shows further that the lateral wall of the fan box 2 at the associated location has a spring latching device 12 which fits to the plastic plate 11.

During assembly, a spacer member 8 is first screwed to the corresponding kitchen carcass walls left and right on the tabs 9 and the entire extractor hood 1 then pushed up from the bottom up between the spacer members 8. In this case, the spring latching device 12 locks on the plastic plate 11 and holds the hood 1 in the correct position, at least temporarily. Thereupon can be between the spacer elements 8 and the fan box 2 not shown here Querverschraubungen for Fixation and bracing are made and the screw connections between the lower plate 10 of the spacer members 8 and the drawer assembly 3 are made. Then the hood 1 is screwed vertically and horizontally and clamped and held stably between the kitchen carcass walls. The distance between the kitchen corpus walls corresponds to the usual distance for 90 cm cooker hoods, although the fan box 2 is much narrower. Appropriate mounting method with dimensionally different distance components 8 are of course for other dimensions into consideration. In an individual case, it may also be of interest to arrange the fan box 2 asymmetrically relative to the drawer unit 3 or to provide modular sets of spacer components which allow a "series connection" of a plurality of distance components for bridging different distances.

The flush completion of the front wall of the distance components 8 (U-legs) and the upper front surface of the fan box 2 creates a total of a unit that can be used in terms of the geometry of the furniture installation as conventional 90 cm cooker hoods.

The latching attachment described between the spacer components 8 and the fan box 2 corresponds to conventional cooker hoods already known fastening systems, so that the assembly staff, apart from the screwing of the spacer components 8 on the kitchen carcass walls and the screwing between the spacer members 8 and the drawer assembly 3, has to do with known and practiced mounting method.
