Description

{EXTRACTOR HOOD, KIT FOR EXTRACTOR HOODS AND METHOD FOR MOUNTING AN EXTRACTOR HOOD}

The present invention relates to an ejector hood, a kit for the ejector hood and a method of assembling the ejector hood.

In the case of a so-called chimney-shaped ejector hood, the actual hood is fixed to a fan box, which can also be referred to as a fan housing. In the case of a chimney hood, the hood is confined to the top and the outside by a capture panel and functional members such as, for example, electronic members are received in the hood. Also, inside the hood, filter elements covering the inlet of the ejector hood are retained. At the top of the hood the fan box is covered by the year.

The chimney ejector hood is currently manufactured such that the capture panel is screwed with the fan box. In addition, the reinforcement and connecting members are screwed with the capture panel to give the capture panel the necessary rigidity and to be able to secure the function and filter members to the capture panel. Thus, for example, in the rear region of the capture panel, the vertical rear wall portion is screwed with the capture panel. At the bottom, the connecting rails are screwed into the capture panel along the rear edge of the capture panel. Also provided is a reinforcement rail extending centrally along the width of the capture panel. Furthermore, in order to retain the electronic device or at least prevent interference with the electronic device, a shielding plate which is likewise screwed with the capture panel is provided. In addition, a trough shaped guide plate may be secured to the capture panel or to the reinforcing and connecting members to prevent contaminant ingress and to improve air guidance to the air inlet of the fan box. Therefore, in the case of the ejector hood the capture panel represents the support member of the hood.

The shape of the capture panel can vary based on design aspects and mounting space. In this case, the connecting and reinforcing members, the shield plate and the rear wall part depend on the geometry of the capture panel and must be adjusted accordingly. In addition, the shape and dimensions of the rear wall, the connection and reinforcement members and the shield plate depend on the width of the fan box used. Thus far, it has been necessary to manufacture the reinforcement and functional elements corresponding to each type of ejector hood so that the hood can be correspondingly manufactured and connected to the fan box by a capture panel.

DE 299 03 104 U1 describes the type of fastening of the hood (in the document referred to as the hood member). Here, the support frame, which can be inserted into the fan box from the bottom, is fixed to the hood member. Moreover, the hood member is connected to the fan box in the capture panel.

A disadvantage of known flue-type ejector hoods is that a wide variety of components are required in order to be able to implement different forms of ejector hoods (especially capture panels and fan boxes). Moreover, manufacturing is complicated by the large number of connection points and difficult due to the partial weakness of access to the connection points. Finally, there is a disadvantage in that the hood must be completely dismantled from the fan box, usually for repair purposes, or for maintenance work, for example of electronic components arranged in the hood.

It is therefore an object of the present invention to provide a solution that can minimize the variety of parts required to provide different ejector hoods and nevertheless simplify assembly and maintenance of the ejector hoods.

The present invention is based on the recognition that the above problem can be solved by providing a basic structure which serves to support the substantial components of the ejector hood and which can be fixed to the functional and facing parts.

The problem is therefore solved by an ejector hood, in particular a chimney ejector hood, comprising a fan box and a capture panel according to the first aspect. The ejector hood is characterized in that the fan box forms at least the inner frame with the inner frame of the ejector hood and the capture panel is detachably fixed to the basic structure.

The ejector hood according to the invention preferably represents a chimney ejector hood, in particular a wall mounted chimney ejector hood. In this regard, the fan box is at least partly surrounded by a hood and the hood comprises a capture panel on the outer surface and in which the filter member as well as functional members, for example electronic controls of the ejector hood, are housed. The ejector hood is referred to as the chimney ejector hood. The fan box represents the blower and, in some cases, the motor, as well as the housing in which the corresponding electronic components for the blower operation are housed. In the sense of the present invention, a part of the discharger hood is understood as the inner frame of the discharger hood, which comprises a defined interface on the top for fixing to the fan box and at least one interface on the outside for connection with the capture panel. . In addition, additional components of the ejector hood (especially electronic components and filter elements) must also be retained in the inner frame. Preferably the inner frame is further used for the targeted air guidance, from the inlet of the underside of the inner frame towards the air inlet of the fan box. For this purpose the inner frame is preferably formed in the form of a trough, where the trough bottom represents the top surface. According to the invention the facing part of the ejector hood is referred to as a capture panel. In this case the capture panel preferably covers the gap between the outer edge of the ejector hood and the fan box at least towards the top. In the case of the present invention, since the capture panel is not provided with a support function unlike the prior art, the capture panel can represent a pure facing component.

The connection between the fan box and the inner frame preferably represents a fixed connection that can only be separated by a tool. Preferably this connection, in other words the fixing of the inner frame to the fan box, is made by screws. This allows a stable basic structure to be formed in which additional parts of the ejector hood can be constructed. The basic structure is located inside with the ejector hood assembled. In particular, the capture panel is fixed to the basic structure. Also, the year used as the facing portion of the fan box can be fixed to the basic structure. The fastening of the capture panel to the basic structure is a removable connection according to the invention. Particularly preferably the connection between the capture panel and the basic structure in the area of the fan box is a plug-in connection and / or a clamping connection. At the interface of the inner frame to the capture panel, the capture panel can be further connected with the inner frame by screws or other removable connection means. By securing the capture panel to the base structure located inside the ejector hood, the capture panel can be removed from the base structure as needed, but this is also possible without parts of the base structure (especially the inner frame) likewise being removed.

In addition, an inner frame comprising a capture panel and further interfaces for connection with the fan box impart the ejector hood the stability required in the area of the hood. Since this stability is achieved by one part, the inner frame, the number of parts needed to manufacture the ejector hood is minimized and the manufacturing is simplified. In addition, storage and product development for different types of ejector hoods (especially capture panels) are also simplified because only one component, ie the shape of the inner frame, needs to be changed. Finally, the design freedom of the capture panel is also extended through the structure of the ejector hood according to the invention, since the capture panel no longer represents the supporting part, so that the shape and material of the capture panel can be freely selected. .

Preferably the inner frame represents the supporting part of the basic structure. In this regard, the ejector hood, in particular the part to which the further components of the hood are fixed or held, is referred to as the support part. In addition, preferably at least a part of the weight of the components is supported by the component. For this purpose the inner frame can be made of a material having a wall thickness which enables a supporting function. According to an embodiment added or replaced thereto, reinforcements in the form of beads, for example beads, may be formed. Finally, the inner frame may also be provided with fixing devices for holding or fixing the electronic components and / or the filter members. The inner frame is preferably a sheet component manufactured through deep-drawing. In addition, the bent part can be fixed to the inner frame so as not to be separated, and this bent part can be provided with fixing devices, in particular for filter elements. The bending part is also referred to as the rear wall of the inner frame.

According to one embodiment, the inner frame has a trough-shaped base body, and the bottom of the base body is provided with an interface for fixing to the fan box. The interface represents in particular the contact area in which the fan box lies on the inner frame. In addition, the interface is provided with fastening elements, in particular screw passages, and the inner frame can be screwed into the fan box via these screw passages. In the assembled state, the inner frame is mounted with the trough bottom facing upwards. In addition, a bottom is provided with an air vent, through which air can reach the fan box from the inner frame. The interface is therefore preferably provided at the edge of the vent of the inner frame. In addition to the interface for connection with the fan box, the inner frame is provided with an interface for connection with the capture panel. This interface is disposed on the outer edge or frame of the inner frame. Preferably the interface is formed only by a portion of the outer edge of the inner frame. In particular, the side outer edges of the inner frame are boundaries that allow the capture panel to be secured to the inner frame. Even in this case the interface represents the contact area in which the capture panel lies on the inner frame. The interface is further provided with fastening elements, in particular screw passages, and the inner frame can be screwed with the capture panel via these screw passages.

According to one embodiment, the fan box is provided with two fixed rails, and the capture panel can be detachably connected to the fan box through these fixed rails. The fixed rails may be manufactured integrally with the fan box or preferably fixed to the fan box. The advantage of separate fastening rails is that the shape and material of the fastening rail can be selected corresponding to the function to be performed by the fastening rail. In particular clamping force can be provided to the capture panel via the fastening rails. Especially preferably the rails are provided on the sides of the fan box, in particular in the lower region of the fan box. By providing rails on opposite sides of the fan box, the capture panel can be inserted into the rails from the front for connection with the fan box. The capture panel can then be held in place by the clamping or locking members of the rails. Since the capture panel can be fitted by sliding onto the fan box from the front, the inner frame fixedly connected to the fan box at the bottom of the fan box does not prevent this fitting. In addition, fixing rails, in particular with clamping or locking means, are provided, which makes it possible to remove the capture panel from the fan box without tools. Thus, maintenance or repair of the components covered by the capture panel is simplified.

According to a further aspect the invention relates to a kit for an ejector hood, which comprises a fan box as well as an inner frame. The kit herein is characterized in that the inner frame and the fan box are used for the manufacture of the base structure and the kit comprises at least two capture panels for removable fixing to the base structure.

The kit can produce two different ejector hoods. In this case only the capture panel is different in the ejector hoods. According to the invention, since the capture panel is seated or slipped onto the underlying inner structure, the same basic structure can be used for different capture panels. Unlike the prior art in which the capture panel is a support member and all components have to be formed in accordance with the capture panel, the kit according to the invention has a small number of parts that need to be prepared or developed for manufacturing different ejector hoods. .

Preferably the two or more capture panels of the kit have different shapes. The shape of the capture panels may differ by the geometry of the capture panel and / or its dimensions. If the capture panels differ only in terms of vertical geometry and / or dimensions, the same basic structure, ie the same fan box and the same inner frame, can be used for different capture panels. This corresponds to, for example, capture panels that have a box shape and differ only in height. The kit may also include a capture panel in the form of a box and an additional capture panel in the form of a roof. In both cases, in the kit according to the invention at most the position of the point at which the capture panel is fixed to the fan box will vary. In contrast, the basic structure consisting of the fan box and the inner frame remains the same. It is also possible to compensate for the height difference of the capture panels, preferably by using fixed rails of different heights. Even in this case, the position where the capture panel is connected to the fan box remains the same. The use of the fixed rails is described more precisely with reference to the preferred embodiment later.

If the types of capture panels are distinguished by their width, the kit is provided with only inner frames having different widths. In contrast, the fan box may in some cases remain the same for inner frames having different widths.

According to one embodiment, the kit includes two fan boxes of different widths and three inner frames of different widths. By means of the kit, all ejector hoods containing the desired capture panel and having conventional dimensions can be manufactured. Preferably for this embodiment the kit comprises an inner frame used for ejector hood widths of 30 cm, 60 cm and 90 cm, respectively. The width of the inner frame relative to the ejector hood widths can be 20 cm, 50 cm and 80 cm, respectively. The width of the pan box of the kit can be, for example, 20 cm and 30 cm. Corresponding vents are provided here in the inner frame and the vent widths of the inner frame are equal and 20 cm when the outlet hood widths are between 30 cm and 50 cm and 60 cm. Only if the ejector hood width is 90 cm, the vent of the inner frame is distinguished from the previous case and is 30 cm. Since the vents are the same when the two inner frames have different widths, the same fan box can be used for the two inner frames, so that the number of parts of the kit for manufacturing the different ejector hoods can be further reduced. In addition, the smallest inner frame can be used for fixing the glass shield as a capture panel.

Preferably the inner frame of the kit is provided with predetermined boundaries for the pan box and capture panel. These interfaces are provided at the outer edge of the inner frame and the edge of the vent of the inner frame, respectively. As such, the additional form of the inner frame to the capture panel to be provided on the basic structure is not critical, so that the capture panel can be replaced by another capture panel. This is advantageous over the prior art, where reinforcing and connecting members must be formed to conform to the shape of the capture panel.

The kit may include two securing rails for connecting the capture panel and the fan box, according to one embodiment. The fixed rails are fixed to the opposite sides of the fan box. As such, the connection between the fan box and the capture panel can be achieved by sliding the capture panel onto the fan box. Since the fixed rails represent separate parts, for capture panels with different heights, the fixed rails can be mounted in the fan box corresponding to the position of the connection point between the fan box and the capture panel, or for different capture panels Fixed rails of corresponding height may be used.

According to a further aspect the present invention relates to a method for assembling an ejector hood having a fan box, an inner frame and a capture panel. The assembly method of the present invention is characterized in that the fan box is detachably connected with the capture panel before the fan box is connected with the inner frame.

Since the capture panel is connected with the fan box before the inner frame is secured to the fan box, assembly can be made upside-down. In other words, the bottom of the fan box and the bottom of the capture panel may face the top at assembly. This is desirable because the parts to be connected do not have to be placed on the upper side of the installer. In addition, screw tightening, in which the installer mounts the screws downward, is also desirable from an ergonomic point of view.

According to one embodiment the method steps of assembly of the ejector hood are carried out in a package. Optionally, one or more method steps of attaching the securing rails to the capture panel can be performed before inserting the capture panel into the package, that is, outside the package. In particular, cardboard boxes, in which case product supports can be inserted, are referred to as packaging. It is possible to assemble in a package according to the invention, since the assembly is made such that the ejector hood is located at the top, that is to say that each has access to the underside of the individual parts from the top. An advantage of this embodiment is that an additional packaging step can be omitted. In addition, in the case of the present embodiment, there is no need to insert the fully assembled ejector hood into the package, so that in some cases no damage may occur to the ejector hood.

According to a further embodiment, two fixing rails are detachably connected with the capture panel before the fan box and the capture panel are connected. Then, in a further method step, the capture panel is secured to the fan box via fixing rails. The rails here are especially used for sliding the capture panel into the fan box or withdrawing the capture panel from the fan box. The direction in which the insertion and withdrawal is made is oriented horizontally, that is, the capture panel is fitted while sliding on the fan box from the front. Since the fixed rails are connected with the capture panel before being fixed to the fan box, the subsequent step of connecting the fan box and the capture panel through the fixed rails can be performed in an inverted state in the package. Even during assembly outside the package, space requirements for assembly in the horizontal direction can be minimized by connecting the capture panel and the fixed rails in advance.

Preferably the removable connection between the capture panel and the fan box is via a clamping and / or formally coupled connection or via a locking connection. This type of connection is preferred because the connection between the capture panel and the pan box can be separated without tools.

In contrast, the connection between the fan box and the inner frame is preferably made via screws or rivets. The fan box and the inner frame form the basic structure of the ejector hood. Thus, a fixation is desired in which relative movement between parts can be reliably prevented in all directions.

According to one embodiment the method according to the invention is:

1) slipping the securing rails on the inner folded edge of the capture panel;

2) placing the capture panel on the product support;

3) inserting a fan box into the capture panel, in particular within the inner edge of the capture panel;

4) screwing the fixed rails and the fan box,

5) wiring the electrical components of the ejector hood,

6) inserting and screwing the light strip into the capture panel;

7) Secure the inner frame to the fan box and step the inner frame onto the capture panel;

8) screwing the fan box and the inner frame.

The method steps mentioned are preferably executed in the order specified. However, steps 1 and 2 may be executed in a reversed order. This is especially possible when the ejector hood is not assembled in the package but there is sufficient assembly space in the horizontal direction. It is also possible in accordance with the invention to first place the pan box on a product support which can be placed in the package, and then to mount the capture panel from the bottom with the fixing rails fixed to the surface.

The fixing of the inner frame to the fan box made in step 7 may simply place the inner frame on the flanges of the bottom of the fan box. However, the inner frame may be secured to the fan box by hoe or other fastening means before screwing into the fan box.

Further, following or before screwing the fan box and the inner frame, the capture panel may be screwed with the inner frame at the interfaces with the inner frame. This connection is especially used for grounding and can reliably prevent relative movement between the capture panel and the inner frame. However, this relative movement is already at least partly suppressed by the fastening of the capture panel to the fan box.

The light strip is inserted into the capture panel so that the strip rests on a connecting web extending inwardly from the outer edge of the capture panel. The connecting web here is preferably provided in a frame that extends along the outer edge of the capture panel at the underside of the capture panel.

After screwing the fan box and the inner frame, and optionally after screwing the inner frame and the capture panel, filter elements in the form of filter cartridges are inserted into the inner frame. The filter elements are fixed to the back of the inner frame and to the back of the light strip, in particular fastened or interlocked. For this purpose the back of the inner frame has a greater height than the further inner frame.

The advantages and features described in relation to the ejector hood according to the invention apply not only to the kit according to the invention and to the method according to the invention (if applicable), but also to the opposites respectively.

In the following the invention is again described according to the accompanying drawings.

In the drawings like parts are designated by like reference numerals and the structure and function of the same parts are described only once in some cases.

An embodiment of the ejector hood 1 according to the invention shown in FIG. 1 comprises a fan box 2, which consists of a box-shaped base body 20 and flanges (at the side of the underside of the fan box). 21 is provided, these flanges extending outwardly from the sides of the base body 20 respectively. The ejector hood 1 also comprises an inner frame 3, the upper surface of which is connected to the fan box 2, in particular to the flanges 21. The inner frame 3 comprises a trough type main body 32. At the bottom of the base body 32, a rectangular vent 33 is provided. The further structure of the inner frame 3 is described more precisely later in connection with FIGS. 3 to 6.

The ejector hood 1 also includes a capture panel 4 which is fixed to a basic structure consisting of a fan box 2 and an inner frame 3. The capture panel 4 comprises a cavity at the back, the size of which corresponds at least to the size of the underside of the fan box 2. On the inner side of the cavity, the capture panel 4 comprises three inner sides with one inner fold edge 42 oriented in the downward direction. Into the inner frame 3 filter elements 7 representing the filter cartridge are inserted. The ejector hood 1 also comprises a light strip 6 into which the lighting means 61 are inserted, in which the lighting means are connected via a wiring 62. Finally the ejector hood 1 comprises an actuating member 8 which is fixed to the capture panel 4 via fixings 81.

Fixed rails 5 are provided which are fixed to the fan box 2 for the removable connection of the capture panel 4 to the fan box 2. These fixing rails 5 are in particular fastened to the flange 21 of the fan box 2, which extends outwards from the lower edge of the base body 20 of the fan box 2 on the sides.

2 shows a schematic rear view of an embodiment of an ejector hood 1 according to the invention. The ejector hood 1 is composed of a basic structure formed by the fan box 2 and the inner frame 3. On the basic structure the capture panel 4 slides in from the front. This direction of movement is indicated by a double arrow in FIG. 1.

3 shows three inner frames 3 which can be used for the kit according to the invention. The inner frame 3 shown on the right side can be used for narrow capture panels with a width of 30 cm, for example. Alternatively, the inner frame 3 can also be used for an ejector hood 1 in which a glass plate is provided on the inner frame. In FIG. 3 the intermediate inner frame 3 can be used for an ejector hood 1, for example having a width of 60 cm. The inner frame 3 shown on the left side in FIG. 3 can be used for example an ejector hood 1 having a width of 90 cm. As can be seen from FIG. 3, the vents 33 of the right and middle inner frames 3 are identical in size. The same fan box 2 can thus be used for the two inner frames 3 to form the basic structure. In contrast, the vent 33 in the inner frame 3 shown on the left has a larger width. In the case of the inner frame, a fan box 2 having a larger width is used. The fan box 2 with a larger width can also be used in the inner frame 3 shown in the middle in FIG. 3. This further reduces the number of parts required in the kit.

4 to 6 show different embodiments of the inner frame 3 more precisely. 4 shows an embodiment of the inner frame 3 which can be used when the ejector hood width is 30 cm. The inner frame can also be used in a capture panel that represents a glass shield. The embodiment of the inner frame 3 shown in FIG. 5 is used when the ejector hood width is 60 cm, and the embodiment of FIG. 6 is used when the ejector hood width is 90 cm.

The inner frames 3 each comprise a trough-shaped base body 32 with the bottom of the trough oriented towards the top. At the bottom of the base body 32 is provided a rectangular vent 33 which is limited by the inner edge 36 of the inner frame 3. Along the inner edge 36 an interface S is formed for connection with the fan box 2. In the illustrated embodiment, the region is provided with screw holes 361. In addition, in the case of the wide inner frame 3 according to FIGS. 4 and 6, a bead 34 is formed between the inner edge 36 and the outer edge 35 of the basic body 32, and these beads have an inner frame. It can be used to increase the stability of (3) and to accommodate components such as, for example, electrical components. In addition, the beads 34 may be manufactured in the inner frame 3 in the manufacture of the inner frame 3, in particular during the deep drawing process.

The rear wall 31 is provided at the rear of the inner frame 3, respectively, which is fixedly connected to the trough-shaped base body 32, for example by clinching or riveting. The rear wall 31 is provided with locking openings 312 and into these locking openings the corresponding protrusions of the filter elements 7 can be accommodated so that the filter elements can be fixed to the inner frame 3. .

The assembly of the ejector hood 1 according to the embodiment of the method according to the invention is again described according to FIGS. 7 to 10.

The package 10, in which the ejector hood 1 is assembled, consists of a rectangular cardboard box 101 and rectangular carton tubes inserted into the cardboard box. Wood strips 103 are inserted into the upper edge of the two cardboard tubes 102. For example, the package 10 shown in FIG. 7 is used as a product support in the following. As can also be seen from FIG. 7, the year 9 can be accommodated in the package 10 for future pacing of the pan box 2.

In the first method step the fixing rails 5 are fixed to the inner fold edge 42 of the capture panel 4 (see FIG. 2) along the two sides of the rear cavity of the capture panel 4. The fixed rails 5 are fitted on the inner fold edges 42 of the capture panel 4, in particular from the rear.

In a second method step the capture panel 4 is laid on the wood strips 103 in the orientation shown in FIG. 7. The underside of the capture panel 4 is directed upward. Thus, at the bottom of the capture panel 4, the frame 40 extends along the front and side edges of the capture panel 4, and the connecting web 41 following this frame is visible and accessible in an inverted state. . The fan box 2 is then inserted first through the cavity of the capture panel 4 upwards until the flanges 21 abut the fixed rails 5. In the fan box 2 the necessary fan and electronic components and in some cases the wiring harness are already assembled. The flanges 21 are then screwed into the fixed rails 5. In this state, the wiring can be connected.

Alternatively, the second method step may be carried out such that the pan box 2 is first inserted between the cardboard tubes 102 with the top face up until the flange 21 of the pan box lies on the edge of the cardboard tubes 102. have. The capture panel 4 is then placed on the fan box 2 with its fixed rails 5 mounted thereon. The fixed rails 5 here surround the flange 21. In this position the capture panel 4 is thus supported on the flange 21 via fixing rails 5. This prevents the scratching of the capture panel 4 which may occur through contact of the capture panel with the wood strips 103 when the order is reversed as described above.

In a subsequent method step as shown in FIG. 8, the light strip 6 is optionally screwed into the capture panel 4 together with the pre-inserted illumination means 61, and the illumination means 61 is wired. Can be connected via the poles 62. The light strip 6 is arranged along the front of the capture panel 4, in particular along the front edge 40 of the capture panel 4.

Subsequently, the inner frame 3 is inserted into an area of the underside of the capture panel 4 which is not yet covered by the light strip 6 as shown in FIG. 9. Here, the bottom of the trough type main body 32 faces the fan box 2 side. The inner frame 3 is fastened to the rear region of the fan box 2 and rests on the connecting webs 41 of the capture panel 4, which are at the bottom edge 40 of the capture panel 4. Toward the bottom. The inner frame 3 is then screwed into the flanges 21 of the fan box 2. The screws here are guided along the inner edge 36 via threaded holes 361 provided in the interface S. In addition to this the inner frame 3 is screwed with the connecting webs 41 at the sides of the capture panel 4.

Finally, the filter elements 7 are inserted in the area between the back or rear wall 31 of the inner frame 3 and the back of the light strip 6. The state of the ejector hood 1 thus assembled is shown in FIG. 10.

According to the invention standardization is achieved in the manufacture of an ejector hood, in particular a chimney ejector hood, by providing a basic structure consisting of a fan box and an inner frame and defining the interfaces in the inner frame. In this regard, based on the above standard, the same parts can be used even for special structural forms (eg, when the width of the ejector hood is excessively large, such as 120 cm), thereby further reducing the complexity.

Through standardizing filter sections for 60/70 cm devices and 90/100 cm devices, the light strip can be standardized in two widths and the filter element in one width for the present invention. The filter elements and the light strips used in the wall mounted chimney ejector hood are similarly used in an ejector hood with a 120 cm width and an independent chimney ejector hood.

By defining the interfaces in the inner frame the ejector hood can be constructed in a modular fashion in the future. In this case, you only need to redesign each of the parts that are important for your design.

The invention has in particular the advantage that the device structure is clearly simplified. In addition, development costs can be reduced and development can be focused on sales-related features. Therefore, the project progress period is further shortened. In addition, planning and management efforts at the plant are reduced. You can also consider logistics simplification and new logistics concepts. Finally, obvious cost savings are provided based on one-time spending on new products, materials and wages.
