Description

Technical Field [0001] The present invention relates to an ejector hood, an ejector hood kit, and an ejector hood assembly method.

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

In the case of a so-called chimney-shaped ejector hood, the actual hood is fixed to a fan box, which may also be referred to as a fan housing. In the case of a chimney-type hood, the hood is limited to the upper and the outer sides by the capture panel and functional members such as, for example, electronic components are received in the hood. Further, filter members covering the intake port of the ejector hood are held in the hood. At the top of the hood, the fan box is covered by the year.

Currently, the chimney-like ejector hood is manufactured such that the capture panel is threaded with the fan box. Also, to provide the required rigidity to the capture panel and to enable the function and filter members to be secured to the capture panel, the reinforcing and connecting members are threadedly engaged with the capture panel. Thus, for example, in the rear region of the capture panel, the vertical rear wall portion is threaded with the capture panel. On the underside, the connecting rails are screwed into the capture panel along the rear edge of the capture panel. Also provided is a reinforcing rail extending centrally along the width of the capture panel. Furthermore, a shielding plate, which is likewise screwed with the capture panel, is provided to hold the electronic device or at least prevent interference with the electronic device. A trough-shaped guide plate may also be secured to the capture panel or to the reinforcement and connecting members to prevent contaminant entry and 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 may vary based on the design perspective and the mounting space. In this case, the connecting and reinforcing members, the shielding plate and the rear wall portion are in accordance with the geometry of the capture panel and must be adjusted accordingly. In addition, the shape and dimensions of the rear wall portion, the connecting and reinforcing members, and the shielding plate depend on the width of the fan box used. Hitherto, therefore, it has been necessary to fabricate reinforcing and functional members corresponding to each type of ejector hood, so that the hood can be correspondingly manufactured and connected to the fan box by the capture panel.

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

A disadvantage of known chimney-type ejector hoods is that a wide variety of components are required to enable different forms of ejector hoods (especially capture panels and fan boxes) to be implemented. Furthermore, manufacturing is complicated by the large number of connection points and the accessibility of the connection points is partially hampered by the partial weakness. Finally, there is a disadvantage that the hood must be completely dismantled from the pan box, for example, for repair purposes, or for maintenance operations on electronic components disposed 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 hood.

The present invention is based on the recognition that the above problem can be solved by providing a basic structure which serves to support substantially the constituent parts of the ejector hood and which can be fixed to the functioning 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 a basic structure with at least the inner frame of the ejector hood and the capture panel is releasably secured 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 connection, the fan box is at least partly surrounded by the hood and the hood comprises a capture panel on the outer surface and the filter member is accommodated in the interior of the hood, as well as functional members such as an electronic control device of the ejector hood, The ejector hood is referred to as the chimney ejector hood. The fan box represents a housing in which blowers and, optionally, motors, as well as corresponding electronic components for blower operation, are housed therein. In the sense of the present invention, the part of the ejector hood that includes the interface defined for fixation to the fan box on the top side and one or more interfaces for connection to the capture panel on the exterior side is understood as the inner frame of the ejector hood . In addition, the inner frame must also retain the additional components of the ejector hood, particularly the electronic components and filter members. Preferably the inner frame is used in addition to the desired air guidance from the intake port on the underside of the inner frame to the air inlet of the fan box. To this end, the inner frame is preferably formed in the form of a trough, wherein the trough bottom represents the top surface. In accordance with the present invention, the paced 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 toward the top. In the case of the present invention, the capture panel does not have a support function different from the prior art, so that the capture panel can display pure pacing parts.

The connection between the fan box and the inner frame represents a fixed connection, which can preferably be separated only by a tool. Preferably, this connection, i. E. Fixing of the inner frame to the fan box, is accomplished by means of screws. So that a stable basic structural part can be formed in which additional components of the ejector hood can be constructed. The basic structure is located inside with the ejector hood assembled. Particularly, the capture panel is fixed to the basic structure. In addition, the flue used as the facing portion of the fan box can be fixed to the basic structure portion. Fixation of the capture panel to the base structure is a detachable connection in accordance with the present invention. Particularly preferably, the connection between the capture panel and the basic structure in the region 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 may further be connected to the inner frame by screws or other removable connection means. By fixing 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 possible without the parts of the base structure (especially the inner frame) being removed as well.

In addition, the inner frame, which includes the capture panels and, in addition, the interfaces for connection to the fan box, imparts the required stability to the ejector hood in the area of the hood. Since this stability is achieved by one component, namely the inner frame, the number of parts required to manufacture the ejector hood is minimized and the manufacturing is simplified. In addition, storage and product development for different types of ejector hoods (particularly capture panels) is also simplified because only the shape of one part, i.e. the inner frame, has to be changed. Finally, the design freedom of the capture panel also expands through the structure of the ejector hood according to the invention, since the shape and material of the capture panel can be chosen freely, since the capture panel no longer represents the support part .

Preferably the inner frame represents the support part of the basic structure. In this regard, the components in which the ejector hood, and in particular the additional components of the hood, are fixed or maintained, are referred to as supporting parts. Also preferably, at least a portion of the weight of the components is supported by the component. To this end, the inner frame may be made of a material having a wall thickness that enables the support function. According to an embodiment to be added or replaced, reinforcing portions in the form of beads, for example, may be formed in the inner frame. Finally, the inner frame may also be provided with fastening devices for holding or securing the electronic components and / or filter elements. The inner frame is preferably a sheet metal part manufactured through deep-drawing. In addition, the inner frame can be fixed to the bent part without detaching, and the bending part can be provided with fixing devices particularly for the filter elements. The bending part is also referred to as a rear wall portion 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 the contact area on which the fan box is placed, particularly on the inner frame. In addition, at the interface, fixing members, in particular threaded passages, are provided and the inner frame can be threaded with the fan box through these threaded passages. In the assembled state, the inner frame is mounted such that the trough bottom faces upward. In addition, a vent is provided at the bottom, through which air can reach the interior of the fan box from the inner frame. Therefore, the interface is preferably provided at the edge of the vent hole 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 lateral outer edges of the inner frame are the interfaces that allow the capture panel to be secured to the inner frame. Again, the interface represents the contact area on which the capture panel is placed on the inner frame. Fixing members, in particular screw passages, are additionally provided at the interface, and the inner frame can be threaded with the capture panel through 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 via these fixed rails. The fixed rails may be manufactured integrally with the fan box or preferably fixed to the fan box. An advantage of the separate fixed rails is that the shape and material of the fixed rail can be selected corresponding to the function to be performed by the fixed rail. A clamping force can be provided to the capture panel, in particular via the fixed rails. Particularly preferably, the rails are provided on the sides of the fan box, in particular in the lower area of the fan box. The rails are provided on the side faces opposite to each other in the fan box so that 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. The inner frame fixedly connected to the fan box at the underside of the fan box does not interfere with this fitting, since the capture panel can slide on the fan box from the front. Also, provision of fixed rails, especially with clamping or locking means, allows removal of the capture panel from the fan box without tools. Thus, the maintenance or repair of the components covered by the capture panel is simplified.

According to a further aspect, the present invention relates to a kit for an ejector hood, said kit comprising a fan box as well as an inner frame. The kit of the present invention is characterized in that the inner frame and the fan box are used in the manufacture of the basic structure and the kit comprises two or more capture panels for detachable fastening to the basic structure.

Two different ejector hoods can be produced by the kit. In this case, only the capture panel is different in the ejector hoods. In accordance with the invention, the same basic structure can be used for different capture panels, since the capture panel is seated or slipped on the underlying structural part. Unlike the prior art in which the capture panel is a support member and all the components must be formed in conformity with the capture panel, in the case of the kit according to the present invention, the number of parts to be prepared or developed to manufacture different ejector hoods is small .

Preferably, the two or more capture panels of the kit have different shapes. The shape of the capture panels may differ depending on the geometry of the capture panel and / or its dimensions. If the capture panels differ only in terms of geometry and / or dimensions in the vertical direction, the same basic structure, i.e. the same fan box and the same inner frame, can be used for different capture panels. This corresponds, for example, to 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, the position of the point at which the capture panel is fixed to the fan box varies at most in the kit according to the present invention. On the other hand, the basic structural parts composed of the fan box and the inner frame are kept the same. It is also possible to compensate for height differences of the capture panels, preferably by using fixed rails of different heights. In this case, the position at which the capture panel is connected to the fan box remains the same. The use of stationary rails will be described more precisely with reference to the preferred embodiments hereinafter.

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

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 produced. Preferably, in the case of the above embodiments, the kit comprises an inner frame each of which is 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 may be, for example, 20 cm, 50 cm and 80 cm, respectively. The width of the fan box of the kit may be, for example, 20 cm and 30 cm. Wherein corresponding vents are provided in the inner frame and the width of the vents of the inner frame is equal and 20 cm when the ejector hood width is between 30 cm and 50 cm and 60 cm. Only when the width of the ejector hood is 90 cm, the ventilation hole of the inner frame is distinguished from the previous case and is 30 cm. If the two inner frames have different widths, the number of parts of the kit for manufacturing different ejector hoods can be further reduced since the same vent box can be used for the two inner frames. Also, the smallest inner frame can be used to secure the glass shield plate as a capture panel.

Preferably the inner frame of the kit is provided with predetermined boundaries for the pan box and the capture panel. These interfaces are provided at the outer edge of the inner frame and at the edge of the vent hole of the inner frame, respectively. So that the additional form of the inner frame for the capture panel to be provided on the base structure is not important and thus the capture panel can be replaced by another capture panel. This is preferable to the prior art in which the reinforcing and connecting members must be formed in conformity with the shape of the capture panel.

The kit may include two fixed rails for connecting the capture panel and the fan box, according to one embodiment. The stationary rails are fixed to the side faces which are arranged opposite to each other in the fan box. So that the connection between the fan box and the capture panel can be achieved through the snap fit of the capture panel onto the fan box. Because the fixed rails represent separate components, in the case of capture panels having different heights, the fixed rails can be mounted to the fan box corresponding to the position of the connection point between the fan box and the capture panel, Fixed rails of corresponding heights may be used.

According to a further aspect, the invention relates to a method for assembling an ejector hood with 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 to the capture panel before the fan box is connected to the inner frame.

Since the capture panel is connected to the fan box before the inner frame is secured to the fan box, the assembly can be done upside-down. In other words, the underside of the fan box and the underside of the capture panel can face upward when assembled. This is desirable because the parts to be connected do not need to be disposed on the upper side of the installer. In addition, screw tightening in which the installer mounts the screws downward is also preferable from the viewpoint of ergonomics.

According to one embodiment, the method steps of assembling the ejector hood are carried out in a package. In some cases, one or more method steps of attaching the stationary rails to the capture panel may be performed prior to inserting the capture panel into the package, i. E., Outside the package. In particular, a carton box in which product supports can be inserted internally is sometimes referred to as a package. It is possible to assemble in the package according to the invention, since the ejector hood is located at the top, that is to say the assembly is made so that it can approach the bottom of the individual parts from the top. An advantage of this embodiment is that the additional packaging step can be omitted. Also, in the case of this embodiment, there is no need to insert the fully assembled ejector hood into the package, so that in some cases no damage can occur to the ejector hood.

According to a further embodiment, two fixed rails are detachably connected to the capture panel before connection of the fan box and the capture panel. The capture panel is then secured to the fan box through the fixed rails in an additional method step. Here, the rails are used to slide the capture panel into the fan box, or to pull the capture panel out of the fan box. The direction of insertion and extraction is oriented horizontally, in other words, the capture panel slides and fits onto the fan box from the front. Since the fixed rails are connected to the capture panel prior to being secured to the fan box, subsequently connecting the fan box and the capture panel through the fixed rails can be performed in an inverted state within the package. Even when assembled from the outside of the package, the space requirement for assembly in the horizontal direction can be minimized by previously connecting the capture panel and the fixed rails.

Preferably, the detachable connection between the capture panel and the fan box is accomplished through clamping and / or close fit connection or through a locking connection. This type of connection is desirable because the connection between the capture panel and the fan box can be separated without a tool.

In contrast, the connection between the fan box and the inner frame is preferably via screws or rivets. The fan box and the inner frame form the basic structure of the ejector hood. Therefore, it is desirable that the relative movement between the parts be reliably prevented in all directions.

According to one embodiment, a method according to the present invention comprises:

1) slidably engaging the fixed rails on the folded edge of the capture panel,

2) placing the capture panel on the product support,

3) inserting a fan box within the capture panel, particularly 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 threading the light strip into the capture panel,

7) fixing the inner frame to the fan box, stepping the inner frame on the capture panel,

8) screwing the fan box and the inner frame.

The mentioned method steps are preferably carried out in the stated order. However, steps 1 and 2 may be executed in the reverse 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 place the pan box on a product support which may first be placed in a package and then to seat the capture panel with the fixing rails fixed to the surface from below.

The fixing of the inner frame to the fan box made in step 7 may simply be by placing the inner frame on the flanges of the bottom of the fan box. However, the inner frame may be secured to the fan box via a hoe-type means or other fastening means before being screwed into the pan box.

Also, following, or prior to, the threaded engagement of the fan box and the inner frame, the capture panel may be threadedly engaged with the inner frame at the interfaces with the inner frame. This connection is particularly used for grounding purposes and can reliably prevent relative movement between the capture panel and the inner frame. However, this relative movement is at least partly restrained by fixing of the capture panel to the fan box already.

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

Filter elements in the form of filter cartridges, for example, are inserted into the inner frame after the screw connection of the fan box and the inner frame and, optionally, the threading of the capture frame with the inner frame required. The filter members are fixed to the back surface of the inner frame and the back surface of the light strip, and are particularly fastened or engaged. To this end, the back surface of the inner frame has a greater height than the additional inner frame.

Advantages and features described in connection with the ejector hood according to the invention apply not only to the kits according to the invention and to the method according to the invention (but only if applicable), but also vice versa.

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

The embodiment of the ejector hood 1 according to the present invention shown in Fig. 1 comprises a fan box 2, the fan box is composed of a box-shaped basic body 20 and flanges 21 are provided, and these flanges extend outwardly from the sides of the basic body 20, respectively. The ejector hood 1 also includes an inner frame 3 and the upper surface of the inner frame is connected to the fan box 2 and in particular to the flanges 21. The inner frame 3 includes a trough type basic body 32. At the bottom of the basic body 32, a rectangular vent 33 is provided. The additional structure of the inner frame 3 will be described more precisely hereinafter with reference to Figs.

The ejector hood 1 also includes a capture panel 4 which is fixed to the basic structure composed of the fan box 2 and the inner frame 3. The capture panel 4 includes a cavity in its rear surface and the size of the cavity corresponds at least to the size of the underside of the fan box 2. On the inner side of the cavity portion, the capture panel 4 includes three inner side edges 42, each of which is oriented in the downward direction. Into the inner frame 3, there are inserted filter elements 7 which represent filter cartridges. The ejector hood 1 also includes a light strip 6 into which the lighting means 61 are inserted, and the lighting means are connected via a wiring 62. Finally, the ejector hood 1 includes an actuating member 8 fixed to the capture panel 4 via the fixing portions 81.

There are provided fixing rails 5 fixed to the fan box 2 for detachable connection of the capture panel 4 to the fan box 2. These fixed rails 5 are fixed to the flange 21 of the fan box 2 in particular and the flanges extend outwardly from the lower edge of the basic body 20 of the fan box 2 at the sides.

Fig. 2 shows a schematic rear view of an embodiment of an ejector hood 1 according to the invention. The ejector hood (1) is constituted by a basic structure portion formed by the fan box (2) and the inner frame (3). On the basic structural part, the capture panel 4 slides and fits from the front. Such a moving direction is indicated by a double arrow in Fig.

Figure 3 shows three inner frames 3 that can be used for the kit according to the invention. The inner frame 3 shown on the right can be used for a narrow capture panel having a width of, for example, 30 cm. Alternatively, the inner frame 3 may also be used for the ejector hood 1 provided with a glass plate on the inner frame. In FIG. 3, the middle inner frame 3 can be used for the ejector hood 1 having a width of, for example, 60 cm. The inner frame 3 shown on the left in Fig. 3 can be used for the ejector hood 1 having a width of, for example, 90 cm. As can be seen from Fig. 3, the vents 33 of the right and middle inner frames 3 are the same size. Therefore, in the case of the two inner frames 3, the same fan box 2 can be used to form the basic structure. On the other hand, 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. Further, the fan box 2 having a larger width can also be used in the inner frame 3 shown in the middle in Fig. As a result, the number of components required in the kit is further reduced.

4 to 6, different embodiments of the inner frame 3 are shown more precisely. Fig. 4 shows an embodiment of the inner frame 3 which can be used when the ejector hood width is 30 cm. The inner frame may also be used in a capture panel that represents a glass shielding plate. 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 frame 3 each comprises a trough-shaped base body 32 and the bottom of the trough is oriented towards the top. The bottom of the base body 32 is provided with a rectangular vent 33 which is limited by the inner edge 36 of the inner frame 3. An interface S for connection with the fan box 2 is formed along the inner edge 36. In the illustrated embodiment, screw holes 361 are provided in the region. 4 and 6, a bead 34 is formed between the inner edge 36 and the outer edge 35 in the basic body 32, and these beads are formed in the inner frame 36, Can be used to increase the stability of the device 3 and also to accommodate components such as, for example, electrical components. In addition, the beads 34 can be produced in the inner frame 3 during the manufacture of the inner frame 3, in particular during the deep drawing process.

On the rear surface of the inner frame 3, respectively, a rear wall portion 31 is provided, which is fixedly connected to the trough-type basic body 32 through, for example, clinching or riveting. The rear wall portion 31 is provided with locking openings 312 and the corresponding protrusions of the filter members 7 can be received in these locking openings so that the filter members 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 in accordance with Figs.

The package 10 in which the ejector hood 1 is assembled is comprised of a rectangular carton box 101 and carton tubes 102 inserted in the carton box. Wood strips 103 are inserted into the upper edges of the two carton tubes 102. For example, the package 10 shown in Fig. 7 is used as a product support in the following. 7, the flue 9 can be received in the package 10 for future pacing of the fan box 2.

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

In the second method step, the capture panel 4 is placed on the wood strips 103 in the orientation shown in FIG. Here, the bottom surface of the capture panel 4 faces upward. Whereby the frame 40 at the bottom of the capture panel 4 extends along the front and side edges of the capture panel 4 and the connecting web 41 following this frame is viewable and accessible in an inverted state . The fan box 2 is first inserted through the cavity of the capture panel 4 to the top surface until the flanges 21 abut the stationary rails 5. In the fan box 2, the necessary fan parts and electronic components and the case wiring harness are already assembled. The flanges 21 are then threaded with the fixed rails 5. The wiring can be connected in this state.

Alternatively the second method step can be performed such that the fan box 2 is first inserted into the top surface between the cardboard tubes 102 until the flange 21 of the fan box lies on the edge of the cardboard tubes 102 have. The capture panel 4 is then placed on the fan box 2 with the fixed rails 5 mounted on it. Here, the fixed rails 5 surround the flange 21. Thus, at this position, the capture panel 4 is supported on the flange 21 via the fixed rails 5. Whereby scratching of the capture panel 4, which may occur through contact of the wood strips 103 with the capture panel, is prevented if the sequence is reversed as described above.

8, the light strip 6 is inserted and screwed into the capture panel 4, optionally with the pre-inserted lighting means 61, and the lighting means 61 is inserted into the capture panel 4, (62). ≪ / RTI > The light strips 6 are arranged along the front face of the capture panel 4, in particular along the front edge 40 of the capture panel 4.

Then, as shown in Fig. 9, the inner frame 3 is inserted into the area of the bottom surface of the capture panel 4, which is not covered by the light strip 6 yet. Here, the bottom of the trough type basic body 32 faces the fan box 2 side. The inner frame 3 is anchored in the rear region of the fan box 2 and rests on the connecting webs 41 of the capture panel 4 which are connected to the edges 40 of the capture panel 4 To the lower side. The inner frame 3 is then screwed into the flanges 21 of the fan box 2. Where the screws are guided along the inner edge 36 through the threaded holes 361 provided in the interface S. In addition, the inner frame 3 is threaded with the connecting webs 41 at the sides of the capture panel 4.

Finally, the filter members 7 are inserted in the region between the rear face of the inner frame 3 or the rear wall portion 31 and the back face of the light strip 6. The state of the assembled ejector hood 1 is shown in Fig.

According to the invention, a 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 components can be used in a particular configuration (e.g., even when the width of the ejector hood is excessively large, such as 120 cm, thereby further reducing complexity).

By standardizing filter sections for 60/70 cm devices and 90/100 cm devices, the light strips can be normalized to two widths and the filter elements to one width for one embodiment of the present invention. The filter elements and light strips used in the wall-mounted chimney-type ejector hood are similarly used in ejector hoods having a width of 120 cm and independent chimney-type ejector hoods.

By defining the interfaces in the inner frame, the ejector hood can be configured in a modular fashion in the future. In this case, only the parts that are important for the design need to be newly designed.

The present invention particularly has 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 duration of the project is further shortened. Also, the planning and management effort at the factory is also reduced. In addition, logistics simplification and new logistics concepts can be considered. Finally, there is a clear cost savings based on a single cost outlay on new products, materials and wages.
