Description

Cooking fume extractor with fixing device for loading into hanging cabinet

Technical Field

The invention relates to a range hood with a fan housing and a fitting serving as a fixing device for fitting into a wall cupboard.

Background

The extractor hood is produced and delivered by the manufacturer of the household appliance. In order to use the extractor hood in kitchen appliances, it is also necessary to fit it into kitchen furniture, usually a wall cupboard. This operation can be performed during the manufacturing of the wall cabinet. It is common to incorporate the range hood into the cabinet on site because this simplifies the suspension, positioning and securing of the cabinet by improving the accessibility of the interior space of the cabinet during installation of the kitchen appliance in the kitchen.

However, it has been found that it is difficult to mount the range hood in the cabinet, since the entire range hood frame usually faces downwards and completely covers the bottom of the cabinet, so that the interior of the cabinet can no longer be reached from below when the range hood is in its mounted position. The extraction hood is therefore usually delivered in such a way that it is divided into at least one basic frame and several fixing and covering elements to be mounted during the installation, so that the basic frame remains accessible during the installation.

In order to be able to fix the extractor hood in the wall cupboard, several fittings are used which enable the connection of the extractor hood to the wall cupboard. To reliably fix the range hood, several steel plate folds are usually used, one of which is screwed to the cabinet at each corner of the cabinet. The positioning and fixing of the steel plate bending piece are easy to make mistakes and time-consuming. After the steel plate bending piece is installed, the range hood is in threaded connection with the steel plate bending piece. This is not easy to handle, since the extraction hood must be held in the installed position during the screwing with the steel plate bend. It is often the case that a mistake in the installation of the steel plate bending piece is detected, so that the range hood needs to be removed again, the steel plate bending piece with the wrong installation is detached and reinstalled, and then the range hood needs to be put in place again.

Disclosure of Invention

The invention aims to simplify the installation of a range hood in a wall cabinet.

The above object is achieved by the extractor hood according to the invention in that a frame element is used as a fitting for connecting the extractor hood to a wall cupboard, which frame element has at least one first frame section which comprises a vertical abutment surface for abutment and fixing on a side wall of the wall cupboard and has a second frame section which in the fitted position of the extractor hood partially grips the fan housing from above, a hook receiving opening is constructed in the frame element, and a hook corresponding to the hook receiving opening is provided on the fan housing.

The frame element can be designed as a separate component that is sufficiently strong to hang the entire range hood on the frame element during installation. One or both frame members can be quickly and easily secured in the cabinet. And the wall cupboard has no contents, so that all the wall cupboard is easy to touch. Thus, installation can be accomplished using only a single fitting or two fittings in the wall cabinet. Since the extractor hood is hung on the frame element by means of the hooks during the installation, the installer no longer needs to hold the extractor hood during the establishment of the final connection to the cabinet. After the hook is hung in, both hands of the installer are free, so that the rest of the fixing operation is completed. In the case of a hood hanging on a hook, the hood needs to be pushed into its final position with only a small amount of movement, so that the alignment of the hood can also be greatly simplified and accelerated.

In the case of the hooks and hook receiving openings mentioned above, these concepts are not limited to a narrow technical meaning. As an alternative to a hook, it is also possible to use another catch member which at least partially snaps into the receiving opening, thereby holding the extractor hood. In this way, the engagement member and the receiving opening are further fixing elements of the fixing device. According to the invention, grooves, openings, slots, cuts, recesses and through-holes can also be used as receiving openings, for example. The snap members may also be referred to as, for example, tabs, snap flanges, clips, arms, and movable tongues. The snap-in member may be left in its retaining position by gravity alone, but other securing means may also be employed, such as a clamping connection, a snap-in connection or a snap-in connection. The clamping component of the fixing device is at least partially clamped into the accommodating opening of the fixing device. However, it is within the scope of the invention for the latching element to also pass through the receiving opening and, as the case may be, project out of the receiving opening.

By means of the frame element, the number of parts required for mounting the extractor hood is reduced. The number of screws required for fixing and the installation costs associated therewith are also reduced. Since the hook is suspended in the frame element, the first connection of the extractor hood to the frame element can be realized by simply guiding, inserting, pushing and/or turning the hook into the hook receiving opening. This also simplifies the installation even further. In particular, the hood can be held, for example, in a first position by means of hooks, while the final fixing in the cabinet is achieved by means of further fixing elements after the hood has been hung in the hook receiving opening. In this way, the extraction hood can be screwed finally, for example by means of screws, onto the frame element and/or onto the cabinet. During this time, the range hood can be brought into a second position in which the range hood is not or not completely retained by the hook. But this is by no means a disadvantage. The installation of the extraction hood is ultimately simplified, since the risk of incorrect installation is reduced by the frame element.

According to one aspect of the invention, the second frame section forms a horizontal abutment surface for abutment to the bottom of the fan housing and/or the cabinet. A more precise alignment and positioning of the fan housing in the interior space of the cabinet is achieved by the horizontal abutment surface.

According to one aspect of the invention, the frame element extends from one side wall to the opposite side wall over the entire inner width of the cabinet. In the case of an extension over the entire inner width of the cabinet, the frame element can be supported well on both end sides thereof. Thereby further reducing the risk of mis-installation. Preferably, the frame element with the at least two first frame sections can be supported on the wall cupboard by means of a respective vertical abutment surface. The at least two, preferably exactly two first frame elements are substantially, preferably exactly perpendicular to the second frame section.

The "approximate" concept is given a tolerance range which is reasonable from an economic and technical point of view for a person skilled in the art, so that corresponding features can still be identified or still be realized.

According to one aspect of the invention, the frame element has an arcuately extending shape. This contributes to a good force distribution within the frame element. The arched shape can be realized, for example, as follows: a flat plate is bent several times, so that two side flanges extending in the vertical direction in the installed position, at least two obliquely extending cross members and a horizontally extending center flange are produced. The outer contour of the range hood is surrounded by the arch shape.

Preferably, in this preferred embodiment, the at least one first frame section and the second frame section have an inner angle α of approximately 90 ° to each other, wherein preferably at least two, further preferably exactly two first frame sections are provided, if exactly two first frame sections are provided, exactly two connecting sections are provided between the two first frame sections and the second frame section, wherein according to the invention the two connecting sections are provided in mirror symmetry to each other between the first and the second frame section, respectively.

If the concept of "about" is used in connection with a value or range of values within the scope of the present invention, then the usual tolerance ranges known to those skilled in the art are meant. In particular, a tolerance of. + -. 20%, preferably. + -. 10%, more preferably. + -. 5% is used.

In a preferred embodiment of the invention, the frame element has a second frame section, at least two connecting sections and at least two first frame sections. Preferably, the second frame section and the two connecting sections form three sides of a trapezoid, preferably an isosceles trapezoid, in side view, wherein the fourth and missing side to be supplemented is the base side of the trapezoid.

According to one embodiment of the invention, the first frame section and the connecting section have an internal angle γ with respect to one another, which is preferably in the range from about 95 ° to about 175 °, more preferably in the range from about 120 ° to about 160 °, and particularly preferably in the range from about 135 ° to about 145 °.

According to one aspect of the invention, the second frame section and the connecting section are at an internal angle β to each other, which is preferably in the range from about 95 ° to about 175 °, more preferably in the range from about 110 ° to about 140 °, and particularly preferably in the range from about 125 ° to about 135 °.

According to one aspect of the invention, the hook receiving opening is constructed between the first and second frame sections. This region is particularly suitable for forming the hook receiving opening, since the hook receiving opening is in this case spaced from the side walls, so that the hook can be hooked in with greater ease, but is spaced from the central region of the interior space of the cabinet by a sufficient distance, so that the weight of the extractor hood can be introduced in the transverse direction of the cabinet with reduced leverage and improved balance. Preferably, the hook receptacle is formed on or in the at least one connecting section.

According to one aspect of the invention, the frame element has reinforcing ribs on its bottom side or top side. The strength of the frame element is increased by the reinforcing ribs. In the case of the frame element being embodied as a sheet metal part, the reinforcing ribs can also be embodied as lateral chamfers.

According to one aspect of the invention, the hook receiving opening is a recess constructed in the frame element, the width of which is larger than the hook. Based on the larger width, the hood suspended in the hook receiving opening can be moved in the lateral direction by the hook, thereby precisely aligning the hood under the cabinet. This eliminates the need to position the frame element in the cabinet in a millimeter accurate manner. According to the invention, the hook corresponding to the hook receiving opening is constructed as follows: the end region of the hook passes through the hook receiving opening. The end region of the hook, which end region passes through the hook receiving opening, preferably projects through the hook receiving opening and bears with an inner surface against an outer side face of the frame element, in particular against a connecting section of the frame element. Preferably, the outer surface of the end region and at least the outer side of the frame element extend parallel to one another in a side view of the frame element, it being further preferred that the end region of the hook rests with at least one partial region, preferably substantially over the entire surface, of its inner surface against the outer side of the frame element, preferably the connecting section. In this way, forces exerted by the fan housing to be mounted during insertion into the fan housing can be optimally, in particular uniformly, transmitted to the frame element.

According to one aspect of the invention, a fixing strip is provided on the first frame section, the frame element being movable in the horizontal direction relative to the fixing strip. In this solution, it is only necessary to connect the fixing strip to the corresponding side wall of the cabinet. No precise positioning and alignment of the frame sections is required during the mounting process, since the frame sections can still be moved in one plane after the fixing strips have been fixed. The fastening strip may be, for example, an upwardly open U-shaped part into which the base of the first frame section is inserted.

According to one aspect of the invention, the second frame section has a through-hole for receiving an air outlet connection of a range hood. In the process of being installed in the range hood, the fan shell can be pushed into the through hole through the exhaust joint. Additional centering and alignment of the fan housing during installation is thereby possible. In particular, the above-described solution can be used in the case where the inner diameter of the through-hole and the outer diameter of the air discharge connection are matched with each other in a manner that no gap or even a slight dimensional deficiency exists, so that the air discharge connection is pushed into the through-hole and the fan housing is tightly fitted in the through-hole.

According to one embodiment of the invention, screw holes for screwing the fan housing to the frame element are formed in the fan housing and/or in the frame element. The screw holes and, optionally, additionally provided screw grooves simplify the final screwing of the fan housing to the frame element.

Further features of the invention are set forth in the appended claims, drawings and description of the drawings. All the features and feature combinations mentioned above, as well as features and feature combinations mentioned below in the description of the figures and/or disclosed individually in the figures, can be combined not only in the manner indicated, but also in other ways or applied individually.

Detailed Description

The extractor hood 2 is shown in fig. 1 assembled with a frame element 4. The frame element 4 has two first frame sections 6 which are adapted to abut to the side walls of the corresponding cabinet by means of vertical abutment faces 12. The frame element 4 also has a second frame section 8 which, in the installed position of the extractor hood 2, partially blocks the fan housing from above. The second frame section 8 forms a horizontal abutment surface 10. This abutment face may abut against the bottom of the cabinet or against the fan housing of the range hood 2. The frame element 4 also has two obliquely running connecting sections 7, which connect the two first frame sections 6 to the second frame section 8.

On the frame element 4, a hook receiving opening 14 is formed, which in the present exemplary embodiment is formed by a recess formed in the connecting section 7 of the frame element 4. In the present exemplary embodiment, an oblique flange, which may also be referred to as a connecting section 7, is provided here, which connects the first frame section 6 to the second frame section 8. The frame element 4 has an approximately arched course in an end view, based on the two first frame sections 6, the two obliquely extending connecting sections 7 and the second frame section 8. Wherein the arched shape is selected such that the frame element 4 at least partially covers the extractor hood 2 from above by means of the arch, wherein the frame element 4 extends over the inner width of the cupboard from one side wall to the opposite side wall.

The hood 2 is hooked into the frame element 4 by means of two hooks 16. The hooks 16 each have an end region 17 which passes through the hook receiving openings 14. The hood 2 is held by the hook 16 at least during installation. After the hooks 16 have been hooked into the hook receiving openings 14, the extractor hood 2 can additionally be screwed or otherwise connected to the frame element 4. Wherein the hook 16 can be removed from the hook receiving opening 14. In any case, the installation is greatly simplified by the hooking of the extractor hood 2 into the frame element 4.

In the present exemplary embodiment, the frame element 4 also has a reinforcing rib 18, which is produced as an end-side chamfer of the respective flange of the frame element 4.

In the region of the horizontal abutment surface 10, the frame element 4 has a through-opening 20. The through hole 20 can be passed through by the exhaust joint of the range hood 2 or the corresponding exhaust pipe.

Screw holes 22 can be provided in the frame element 4 and in the fan housing of the extraction hood 2, which screw holes effect a screw connection between the frame element 4 and the exhaust housing. Advantageously, the threaded bores 22 are matched to one another in such a way that the threaded bores 22 in the installed position of the extractor hood 2 are precisely matched to the frame element 4 in order to screw in the screws.

Fig. 2 is a schematic view of the frame element 4. It can be clearly seen from this that the frame element 4 has an arched shape on the basis of two first frame sections 6, two connecting sections 7 and a second frame section 8.

Fig. 3 is a side view of the frame element 4 and the hood 2 to be connected. The hook 16 and its end region 17 are constructed as some kind of resilient tab which can easily be bent inwards during insertion of the hook 16 into the frame element 4 until the end region 17 can enter the hook receiving opening 14.

Fig. 3 also shows the angle of the first frame section 6 and the second frame section 8 to each other with the connecting section 7, the inner angle α of the first frame section 6 to the second frame section 8 to each other, the inner angle β of the second frame section 8 to each other with the connecting section 7, the inner angle γ of the first frame section 6 to each other with the connecting section 7 of about 141.

For simplicity of handling, the hook receiving openings 14 embodied as recesses in the frame element 4 may have a greater width than the hooks 16 comprising the end regions 17. This is best seen in fig. 4, which is an enlarged detail view of the hook receiving opening 14 indicated by circle a in fig. 1. In this position of the hook 16, the end region 17 passes through the hook receiving opening 14 in such a way that the inner surface of the end region 17 runs parallel to the outer side of the frame element 4 and bears substantially over the entire surface thereof. The hook 16 can be moved back and forth in the direction of the double arrow in the hook receiving opening 14, so that it is not necessary to align and fit the extraction hood 2 in a manner of millimeters precisely with respect to the hook receiving opening 14 during the insertion of the frame element 4. Specifically, due to the large width of the hook receiving opening 14, the hood 2 can be moved forward or backward even after the hood 2 is hung on the frame member 4, so that the hood can be adjusted according to a more accurate fitting position than a wall cabinet.

As an alternative to the recess 14, the frame element 4 can also have a fixing strip, not shown in detail, on which the hook 16 is suspended. The fixing strip can be designed such that the hooks 16 can be fixed in different positions along the fixing strip. The fixing strip extends in an approximately horizontal direction along the inner side of the frame element 4. For example, a fastening strip such as a drawer guide can be used, into which the hooks can be snapped and along which the hooks can be moved back and forth.

The present invention is not limited to the above embodiments. The person skilled in the art can adapt the embodiment in a suitable manner without difficulty to suit the particular application.
