Manufacturing process of an appliance cabinet and cabinet so manufactured

Description

[0001] The present invention relates to a manufacturing process of a cabinet for appliances, in particular household appliances, and an appliance cabinet so manufactured (see DE-A-197 06 285).

[0002] It is known that an appliance cabinet can be manufactured substantially according to two arrangements. A first arrangement comprises a carrying structure for supporting appliance operating components that is closed by substantially planar panels. Said carrying structure may be formed by a box element made of a sheet material bent to an L configuration so as to comprise in a single piece the bottom and a vertical rear wall of the cabinet. The carrying structure is completed by a panel disposed opposite to said vertical wall and connected thereto by means of two upper rails. Planar panels are removable from the carrying structure to give access to the appliance operating components while the latter continue to be supported by the carrying structure. A cabinet of this type, i.e. a cabinet wherein some of its outer walls has a support function for the appliance operational components, is disclosed in the European Patent EP 0208334.

[0003] A structure of this type does not offer sufficient rigidity and requires complicated, time-consuming and thus expensive assembly operations, in particular, it appears rather impractical and inconvenient that the carrying structure for the appliance operating components is formed by a box element made of a sheet material cut to measure and bent to an L configuration. In fact, the manufacturing process of such cabinet arrangement cannot be adapted easily to the production of cabinets having different shapes and dimensions without heavy modifications both in the process steps and in the production equipments.

[0004] According to a second generally known arrangement, an appliance cabinet comprises a supporting frame made of spars, mountings and crossbars on which operational components of the appliance are attached and a plurality of panels removably mounted on the frame. A cabinet of this type, i.e. a cabinet wherein the outer walls have no supporting function is disclosed in the French Patent Application FR 1 520 703.

[0005] A cover for a domestic appliance made of a panel slidably received in a U-shaped part frame formed from a profile strip is disclosed in DE 197 06 285. This disclosure refers only to a portion, in particular a cover, of a domestic appliance cabinet. i.e. a structure for containing the appliance operational components.

[0006] A drawback of this second arrangement is that the supporting frame has to be dimensioned specifically for each kind of appliance according to its volume and overall dimensions. An adjustment of the frame structure dimensions requires necessarily a change of its bar components, therefore a manufacturing process for producing this kind of cabinet is rigid, i.e. unsuitable to be adapted to production of cabinets having different dimensions. A further drawback of such known cabinets is that assembling operations require to weld or fasten each end portion of bars forming the supporting frame. The assembling process results therefore rather long and complicated.

[0007] The aim of the present invention is therefore to solve the noted problems, eliminating the drawbacks of the cited known art and thus providing a manufacturing process of an appliance cabinet allowing the production of cabinets having different dimensional characteristics without modifying the procedural steps of the process.

[0008] Another purpose of the present invention is to provide a manufacturing process of an appliance cabinet that simplifies the cabinet assembling operations and reduces the number of productive equipments needed for making an appliance cabinet.

[0009] A further purpose of the present invention is to provide a manufacturing process of an appliance cabinet wherein the use of standardized components and prefabricated articles is advantageously maximised and the production costs and power consumption are drastically reduced.

[0010] Still another purpose of the present invention is to provide a manufacturing process of an appliance cabinet wherein the time needed for completing the cabinet assembling operations is reduced compared to known cabinet manufacturing processes.

[0011] Another purpose of the present invention is to provide a manufacturing process for the production of cabinets for different uses such as cabinets for household appliance, for electric equipments and so on.

[0012] A purpose of the present invention is to provide an appliance cabinet ensuring an easy and prompt access to the inner region of the cabinet itself, thereby simplifying maintenance operations of appliance operational components housed within the cabinet.

[0013] Still another purpose of the present invention is to provide an appliance cabinet wherein the outer panels of the cabinet have no supporting function for operational components of an appliance.

[0014] Advantages, objects, and features of the invention will be set forth in part in the description which follows and in part will become apparent to those having ordinary skill in the art upon examination of the following or may be learned from practice of the invention. The objects and advantages of the invention may be realised and attained as particularly pointed out in the appended claims.

[0015] The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a part of this specification, illustrate a possible embodiment of the invention and together with the description serve to explain the principles of the invention.

Figure 10 schematically shows a second step of the appliance cabinet manufacturing process according to the present invention;

[0017] Referring to figure 1, a section bar 1 is used in the manufacturing process according to the invention for forming a plurality of modular units 10, 210 (figures 4 and 9) which, in turn, are used to compose a supporting frame as it will be diffusely described below. A section bar 1 suitable for carrying out the manufacturing process of the present invention can be obtained easily by extrusion of a metallic mass. Section bar 1 can have a band-like shape as shown in figure 1 and 2 or it can be formed by two substantially perpendicular elongated walls protruding from a common line of intersection B. Said walls give the bar 1 a substantially L-shaped cross section wherein each wall forms an arm of the "L". The same L-shaped cross section, useful for the construction of a modular unit 10, 210, can be also easily formed starting from a section bar 1 having a band-like shape, i.e. a substantially flat shape, by bending the bar 1 itself along a longitudinal direction B.

[0018] As shown in figure 2, bar 1 comprises a plurality of longitudinal ribs 5 extending along the whole length of the section bar 1. Said ribs 5 form two conjugated surfaces 6 and 7 arranged on opposite sides of the bar 1 respectively on the left and right portions of bar 1 with respect to the longitudinal direction B, i.e. the longitudinal bending line. In this way surfaces 6 and 7 of two section bars 1 can be slidably coupled.

[0019] According to a first embodiment of a modular unit 10 shown in figures 3-5, 8, each end region 2 of a section bar 1 is cut along a longitudinal direction so as to form two bar portions 3 and 4. As shown in figure 1, the longitudinal cut line coincides with the longitudinal direction B on which the bar 1 is bent to give it a L-shaped cross-section, in this way each bar portion 3, 4 carries one of said conjugated surfaces 6 and 7 placed on opposite sides of the bar 1.

[0020] In figure 3 it is shown how a modular unit 10 made according to a first embodiment is formed by bending bar portions 3 and 4 of each end region 2 of a section bar 1. In such figure a right and left view of the same bar 1 is disclosed. Bar portions 3 and 4 are bent one above the other such that, at the end of the bending operation (see figures 4 to 7), a right angle α is comprised between portions 3, 4 and a further right angle β is formed between each portion 3, 4 and a bar part 8 extending between the two opposite end regions 2. As it is diffusely described below, said bar part 8 forms at least a part of an edge of a supporting frame for an appliance cabinet. Overlapping of portions 3 and 4 is favoured by the L-shaped cross section of bar 1. If needed, seats 9 (figure 6 and 7) can be formed on one of said portions 3, 4 to allow one of them to lie down on the other one without forming creases.

[0021] A modular unit 10 made according to a first embodiment has a three dimensional shape reproducing preferably the whole edge and angular portion of a box-like structure. Bar portions 3, 4 of two opposite ends of the same modular unit 10 lie on two parallel planes and are two by two parallel. In addition, bar portions 3, 4 carrying the same conjugated surface 6, 7 are bent so as to be placed on the same side relative to the bar part 8. Even if in figures 4 and 5 modular unit 10 has been shown with bar portions 3, 4 of equal length, it is possible to form such portions 3, 4 having different extensions.

[0022] With reference to figure 8, a supporting frame 11 can be formed associating each other four modular units 10 made according to a first embodiment. Modular units 10 associating step of a manufacturing process according to the invention can be made by simply fixing each other bar portions 3, 4 of said units 10 for example through welding of by fastening means known per se. However, it is preferable first slidably coupling a first bar portion 3 of a first modular unit 10 to a second bar portion 4 of a second modular unit 10 identical to the first one simply mating a first conjugated surface 7 carried by first bar portion 3 with a second conjugated surface 6 carried by second bar portion 4. As the association between portions 3 and 4 is made by overlapping conjugated surfaces 6, 7, it should be appreciated that such surfaces must be formed on opposite sides of bar 1.

[0023] Ribs 5 provided on conjugated surfaces 6 and 7 avoid portions 3 and 4 to slip in a transversal direction with respect to the longitudinal sliding direction. A slidable connection between portions 3, 4 of two modular units 10 allows a manufacturer to adjust the reciprocal positions of said units according to the final dimension required by the appliance cabinet. Such adjustment of the frame 11 dimensions is performed before reciprocally fixing said modular units 10. In this way the same modular units 10 can be used for the production of a large variety of supporting frames 11, and consequently of appliance cabinets, differing only in dimensions and volume. In addition overlapping regions of portions 3, 4 are useful for reinforcing and stiffening the supporting frame.

[0024] Arrows W and D indicate how the first and second conjugated surfaces 6 and 7 can be mated. The same arrows W, D represent also the directions (width and depth) along which dimensions of a supporting frame 11 can be adjusted.

[0025] Once the reciprocal positions of modular units 10 have been determined according to the dimensions of the appliance cabinet to be produced, modular units 10 are fixed by welding and/or by fastening means known per sè, such as screws, rivets and the like. Modular units fixing step takes place in the overlapping region of portions 3 and 4. The so formed supporting frame 11 is shown in figure 10 and serves as a structure on which all operational components of the appliance can be attached. Particular arrangements may be provided on the supporting frame so as to facilitate the attachment of said operational components.

[0026] In figure 9 it is shown a supporting frame 211 to be assembled using eight modular units 210 made according to a second embodiment. In said second embodiment elements in common with the first embodiment have been referenced with the same numbers.

[0027] As far as the bar portions 3 and 4 is concerned, such modular unit 210 is made exactly as already described with reference to the first embodiment 10. Even the section bar 1 can be the same for both embodiments. As it is clear from figure 9, the only difference between the two proposed embodiments consists in that, in the second modular unit 210 embodiment, bar portions 3, 4 are formed only on one end region 2 of bar 1, leaving the other end region 2 L-shaped formed. Bar portions 3 and 4 of the second embodiment of the modular unit 210 have the same constructional and spatial arrangement described with reference to the first embodiment, and therefore it will not further described here.

[0028] A modular unit 210 made according to a second embodiment has a three dimensional shape reproducing an angular portion and part of an edge portion of a supporting frame 211. Such second embodiment of modular unit 210 allows to adjust not only width and depth of the supporting frame 211 as described with reference to figure 8, but also its height. Width and depth of a supporting frame 211 to be formed with eight modular units 210 are adjusted simply sliding a first bar portion 3 of a first modular unit 210 onto a second bar portion 4 of a second modular unit 210 identical to the first one through conjugated surfaces 6, 7 until a predetermined reciprocal position of such units 210 is reached. Arrows W and D in figure 9 show the directions along which frame 211 dimensions can be adjusted by means of a sliding movement of one conjugated surface 6, 7 onto the other. When units 210 are placed in the desired position, overlapping bar portions 3, 4 of two associated units 210 are joined in a manner described with reference to the frame 11 obtained with modular units 10 made according to a first embodiment and depicted in figure 8.

[0029] This process step is made for all the four modular units 210 forming the upper part of frame 211 and for all the four units 210 forming the lower part of the same frame 211.

[0030] When the upper and lower part of frame 211 are completed, such parts can be joined through connecting members 13 having, preferably, an L-shaped form so as to perfectly adhere to bar part 8. Connecting members 13 are provided because conjugated surfaces 6, 7 on vertical bar part 8 cannot overlap once width and depth of supporting frame 211 have been fixed. A selective height adjustment of frame 211 along directions indicated by arrows H shown in figure 9 can be achieved by providing a plurality of holes 14 arranged on members 13 such that each end region 2 of modular units 210 can be fixed on said members 13 in a plurality of positions. For fastening modular units 210 to members 13, holes 15 passing through conjugated surfaces 6, 7 are provided on the end region 2 opposite to the bar portions 3, 4 of each modular unit 210. Before reciprocally fixing the upper and lower part of the frame 211, holes 15 are aligned with holes 14 provided on connecting members 13 for receiving a fastening means like a screw, a bolt or a rivet.

[0031] In figure 9, left upper and lower modular units 210 are shown with the respective end regions 2 in contact, i.e. in a configuration suitable to obtain the minimum height allowed by connecting members 13.

[0032] Evidently, if a continuous adjustment of frame 211 height along directions indicated by arrows H is desired, instead of holes 14, 15, a slot/pin coupling can be provided between connecting members 13 and end regions 2 of bar parts 8, so as to define a range of infinite reciprocal positions between a maximum and minimum height for the upper and lower frame 211 parts.

[0033] In figure 10 it is shown how an appliance cabinet is completed by removably associating one or more panels 12 to a supporting frame 11, 211. Said panels 12 may be easily attached to the frame 11, 211 by snap connectors or threaded connectors not shown in figure 10. In this way, panels 12 can be easily removed when access to operational components of the appliance is needed. In figure 10, panels 12 have been schematically represented as surfaces covering completely each face of the supporting frame 11, 211, however, if desired, each of said face can be covered by two or more panels 12. This may be the case wherein the supporting frame 11, 211 is part of a laundry treating machine, or another household appliance having a door for accessing an inner region of an operational component of the appliance and a control panel for driving the appliance work.

[0034] Conclusively it can be stated that a cabinet produced with a manufacturing process according to the invention has a simplified structure and it is easy to be assembled. The same cabinet allows a manufacturer to reduce necessary equipments for carrying out its production.

[0035] Advantageously a manufacturing process according to the present invention can be used for the production of cabinets for many different kinds of appliances, in particular household appliances, like dishwashers, refrigerators, ovens, laundry treating machines, more particularly clothes dryers and laundry washing machines. According to the proposed invention, appliances having cabinets of different volume and dimensions can be easily produced without changing the manufacturing process steps. Hence, said inventive process is advantageously versatile, economically convenient and realizable by means of automatic machines.
