Abstract
Description
- The present invention relates to a laundry washing machine according to the preamble of Claim 1. Such a laundry washing machine is known from GB-A-1 181 917.
- The conventional laundry washing machine comprises a housing formed of two paint-coated or enameled metal sheets which are each bent to form a front wall and a rear wall, respectively, of the housing and each having connected thereto at one side each thereof, a sidewall portion covering about of the sidewall extension of the housing and each having integral connections to the side edge of the wall, a sidewall portion covering of the sidewall extension of the complete housing so that the metal sheets comprise sidewall portions of differing length connected by the front wall and rear wall, respectively, of the housing.
- Housing structures of laundry washing machines are usually provided with the upper and lower welded strenghtening cross-members, resulting in a rigid, self-supporting structure adapted to support the washing assembly and the various functional components of the machine. The top portion of the housing is covered with a conventional work surface affixed to the housing in a per se known manner. Washing machines of this kind are known from DE-A-2 840 939 and DE-A-3 130201.
- Although laundry washing machines having a housing of the above noted construction operate in a satisfactory manner, they still suffer from certain shortcomings.
- In the first place, the various mechanical and electrical components of the machine are installed in a restricted space within the housing, so that access to them is rather difficult even after the removal of the work surface and the rear panel, whereby repair and maintenance operations and the replacement of damaged components is greatly complicated. On the other hand, as the housing performs the function of the supporting structure for all of the functional components of the machine, and has to this effect to be reinforced in the described manner so as to be able to sustain the mechanical loads exerted thereon during operation of the machine, the manufacture of the housing involves an increased consumption of materials and a great number of manufacturing steps.
- The presence of welded connections in the housing of a conventional washing machine moreover forbids the application of the most recent metal sheet surface treatment technologies, such as for instance a powder spray-coating process, which would otherwise be more convenient from the technical and economical points of view, and does not either permit the employ of pre-coated or enamelled metal sheets which would not require any subsequent surface treatment.
- It is an object of the present invention to overcome the described inconveniences by providing a housing for a laundry washing machine which is of a simple modular construction completely different from that of known washing machine housings.
- The housing under discussion as set forth in the characterizing portion of claim 1 is substantially composed of a rigid support frame of reduced dimensions adapted to support all of the functional components of the machine, and of at least two separate housing elements adapted to be brought into mutual contact in a surrounding relationship to the support frame and the components of the machine and to be releasably connected to the support frame.
- According to the invention, the frame is provided with support elements rigidly affixed thereto as by welding or by other conventional connection means, while the housing elements exclusively serve as the outer casing of the washing machine which may thus be designed to any suitable or desirable configuration. The housing elements may thus be designed as a one-piece construction and finished in a single operation, as they do not require any reinforcement as employed in conventional constructions. The housing elements may thus be formed of traditional metallic materials of reduced wall thickness, resulting in a reduced consumption of material with the attendant economical advantages.
- In addition, these metallic materials may be subjected to more sophisticated and advantageous surface treatments, such as for instance a powder spray-coating treatment, or may even be employed in a surface-finished, for instance pre- painted state, so as to eliminate any further surface treatment of the material itself.
- As the housing elements are not required to have any particular mechanical strength, they may also be made of non-metallic materials such as plastics or the like.
- The characteristics and advantages of the invention will become evident from the following description, given by way of a non-limiting example with reference to the accompanying drawings, wherein:
- fig. 1 shows an exploded perspective view of the various components of a housing of a laundry washing machine in a first embodiment of the invention,
- fig. 2 shows a frontal view of a support frame forming part of the housing shown in fig. 1, with the washing assembly of the washing machine suspended therein,
- fig. 3 shows a cross-sectional view of the support frame taken along the line A-A in fig. 2, and
- fig. 4 shows an exploded perspective view of the various components of a housing of a laundry washing machine in a second embodiment of the invention.
- With reference to fig. 1. there is shown a housing of a laundry washing machine, particularly of the front-charging type, said housing being composed of two
separate housing elements - Each
housing element - In particular,
housing element 5 is formed to have a main wall portion 8 forming the plane front surface of the finished housing, and two planelateral wall portions 9 and 10 extending parallel to one another at right angles to the main wall portion 8 so as to form a portion each of the two lateral surfaces of the finished housing. - Each lateral wall portion terminates in a rectilinear
vertical edge bores 13.Housing element 5 is further formed with an upper through-opening 14 for insertion and securing therein apanel 15 carrying a number of knobs 16 for selecting the various washing programmes of the machine and the electrical components associated with the knobs 16.Opening 14 may also contain additional components of the machine, such as for instance adetergent container 17. - For
stiffening housing element 5, the upper and lower edge portions of main wall portion 8 andlateral wall portions 9 and 10 are bent inwards so as to form anupper ledge - Formed adjacent the lower edges of the
lateral wall portions 9 and 10 ofhousing element 5 arefurther openings 21 for securing the housing element to support frame 7 in a manner to be described. - Mass-produced housing elements of the above described type, although all of the same construction, may be designed with varying exterior appearance so as to distinguish between various models of washing machines.
- The
housing element 6 is substantially of the same construction as thehousing element 5 described above, including a planemain wall portion 22 forming the rear surface of the finished housing, and twolateral wall portions -
Housing element 6 is further formed with inwards bentupper edge portions rectilinear edge portions housing elements - The
lateral wall portions housing element 6 have their lower portions likewise formed withfurther openings 32 for connection to support frame 7. - Examining now figs. 1 and 3, it is noted that the support frame 7 of the housing is substantially composed of two elongate profiled
metal members vertical legs horizontal top portion 37 and dimensioned so as to fit between the twohousing elements - In the example shown, the two
profile members outer profile member 34 being suitably formed for overlapping engagement with therespective edge portions housing elements - The
vertical legs metallic cross members holes 40 and 41, respectively, corresponding to theholes lateral wall portions Cross members feet 42 of rubber or the like supporting the frame on the floor. - The thus composed support frame is of rigid and compact construction so as to efficiently support the washing assembly as well as all of the remaining electrical and mechanical components of the washing machine.
- The support frame may of course also be formed of profile members and cross members of different configuration and with other contours than described above, without leaving the scope of the invention.
- As shown in fig. 2, the washing assembly composed of a
tub 43 and adrum 44 rotatably mounted withintub 43 is suspended in frame 7 by means ofsuspension springs shock dampeners 47, 48 supported bysuitable brackets - With the exception of a
main drive motor 51 suspended fromtub 43, the remaining electrical and mechanical components of the washing machine, which, as already stated, are also supported by support frame 7, are not shown in the drawing. - After the washing assembly and the remaining electrical and mechanical components of the washing machine have been mounted in support frame 7, the assembly of the washing machine is completed by connecting the two
housing elements - According to the invention, this is done by merely aligning
housing elements lateral wall portions vertical edge portions vertical legs - The upper end of the thus formed housing is finally covered by a conventional work surface (not shown) which is fixed in position in a per se known manner.
- Shown in fig. 4 are the structural members of a housing for a laundry washing machine in a modified embodiment of the invention, in which the two housing elements designated 52 and 53 are of a different shape than those of the above described embodiment, while support frame 7 is identical to the one previously described. In the embodiment shown, the
front housing element 52 is formed in one piece with theupper work surface 54, the depth of which corresponds to that of the washing machine itself. - The
rear housing element 53, on the other hand, is of a somewhat smaller height than the rear housing element of the previously described embodiment, so as to properly adapt itself to the modifiedforward housing element 52 and to permit the housing elements to be suitably connected to one another and to support frame 7 in the manner descrbed above. - The modified
housing elements - The advantages obtained by the laundry washing machine of modular construction according to the invention are clearly evident from the above description.
- In the first place, the described machine is of a much simpler construction than known washing machines. Thanks to the fact, that it is composed of pre-assembled modular elements, it can be produced in a more rational manner employing novel production technologies, for instance by the employ of separate assembly lines.
- As the modular elements are interchangeable among another, it is also possible to produce laundry washing machines having identical functional components, but with a variable outer appearance, by employing the same rear housing element and the same support frame in combination with forward housing elements of any desired appearance.
- A further advantage of this type of a laundry washing machine consists in that the function components thereof are readily accessible after dismounting the housing elements from the support frame, so that repair and maintenance work as well as the replacement of any of the components are greatly facilitated.
- As in the described laundry washing machine the support frame is the only structural member to perform a carrying function, lateral vibrations of the machine are practically eliminated. As a result, the housing elements may be formed of a material offering less resistance to mechanical loads, for instance plastics materials, and/or with a reduced wall thickness and without the employ of interior stiffening members as in the past.
- This leads to considerable savings of materials and to a reduction of the required number of working steps in manufacture.
- As the housing elements are finally constructed in one piece and without any welded joints, it is possible to adopt more advanced surface treatment technologies, for instance the powder spray-coating method, or to employ pre-coated metal sheet material which does not require any subsequent surface treatment, resulting in technically and economically advantageous production methods.
