Definitions

  • the present invention relates to a laundry washing machine, particularly of the front-charging type, of a modular construction comprising a housing composed of two separate and mutually engageable housing elements and a support frame adapted to support all of the functional components of the machine and to have said housing elements externally affixed thereto.
  • Conventional laundry washing machines comprise a housing formed of paint-coated or enamelled metal sheet which is bent to form three sides of the housing, namely, a front side and the two lateral sides, the rear side of the housing remaining initially open to be closed by means of an additional rear panel.
  • the thus formed housing structure is provided with upper and lower welded strengthening 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.
  • the various mecanical 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 dismounting of the waork surface and the rear panel, whereby repair and maintenance operations and the replacement of damaged components is greatly ccmplic- ated.
  • 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 housing under discussion is substantially composed of a support frame of reduced dimensions adapted to support all of the functional components of the machine, and of 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.
  • the frame is provided with support elements rigidla 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.
  • 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.
  • 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.
  • a laundry washing machine particularly of the front-charging type, provided with an external housing adapted to enclose and support a washing assembly comprising a tub and a drum rotatably mounted within said tub, as well as all of the electrical and mechanical components of the machine.
  • a laundry washing machine of this type is characterized in that said housing is composed of at least a first and a second housing element adapted to be connected.to one another and each formed as a one-piece construction, and at least one rigid support frame adapted to support said washing assembly and said components of the machine, said housing elements being adapted to be releasably assembled with one another with said support . frame interposed therebetween, and to be covered on top by a plane work surface.
  • a housing of a laundry washing machine particularly of the front-charging type, said housing being composed of two separate housing elements 5 and 6 and a rigid support frame 7, the construction of which will be described in detail hereinafter.
  • Each housing element 5, 6 is formed as a substantially box-shaped casing by suitably punching and bending a single piece of metal sheet.
  • housing element 5 is formed to have a main wall portion 8 forming the plane front surface of the finished housing, and two plane lateral 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.
  • Housing element 5 is further formed with an upper through-opening 14 for insertion and securing therein a panel 15 carrying a number of kncbs 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 a detergent container 17.
  • main wall portion 8 and lateral wall portions 9 and 10 are bent inwards so as to form an upper ledge 18, 19, 20 and a lower ledge (not shown), said ledges having their overlapping end portions secured to one another as by welding or by means of conventional fastener elements.
  • housing element 5 Formed adjacent the lower edges of the lateral wall portions 9 and 10 of housing element 5 are further 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 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 the housing element 5 described above, including a plane main wall portion 22 forming the rear surface of the finished housing, and two lateral wall portions 23 and 24 each forming a part of the respective side surface of the finished housing.
  • Housing element 6 is further formed with inwards bent upper edge portions 25, 26, 27 and lower edge portions, only two of which are visible and designated 28 and 29, and vertically extending rectilinear edge portions 30, 31 provided with holes for connecting the two housing elements 5 and 6 to one another.
  • the lateral wall portions 23 and 23 of housing element:6 have their lower portions likewise formed with further openings 32 for connection to support frame 7.
  • the support frame 7 of the housing is substantially composed of two elongate profiled metal members 33 and 34 connected to one another in side-by-side relationship in a conventional manner and bent in their longitudinal direction to the shape of an inverted letter "U" having two vertical legs 35 and 36 connected to one another by a horizontal top portion 37 and dimensioned so as to fit between the two housing elements 5 and 6.
  • the two profile.members 33 and 34 together form a twin box-shaped section, with the contours particularly-of the outer profile member 34 being suitably formed for overlapping engagement with the respective edge portions 11, 12 and 30, 31 of the two housing elements 5 and 6, said profile member being in addition provided with bores corresponding to those formed in the said edge portions.
  • the vertical legs 35 and 36 have their lower end portions centrally fixed in a conventional manner to a pair of metallic cross members 38 and 39, respectively, formed each with a series of holes 40 and 41, respectively, corresponding to the holes 21 and 32 formed in the respective lateral wall portions 9, 10 and 23, 24.
  • Cross members 38 and 39 are further provided with adjustable levelling 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.
  • the washing assembly composed of a tub 43 and a drum 44 rotatably mounted within tub 43 is suspended in frame 7 by means of suspension springs 45 and 46 anchored to the upper portion of frame 7, and shock dampeners 47, 48 supported by suitable brackets 49, 50 fixedly attached to the lower portion of frame 7.
  • this is done by merely aligning housing elements 5 and 6 with one another and with support frame 7 in the forward and rearward position with respect thereto, and releasably connecting the three structural components by means of self-cutting screws or the like (not shown) threaded into the corresponding holes of the lateral wall portions 9, 10 and 23, 24, of the vertical edge portions 11, 12 and 30, 31 and the vertical legs 35 and 36 of support frame 7.
  • 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.
  • the fron housing element 52 is formed in one piece with the upper work surface 54, the depth of which corresponds to that of the washing machine itself.
  • the rear housing element 53 is of a somewhat smaller height than the rear housing element of the previously described embodiment, so as to properly adapt itself to the modified forward housing element 52 and to permit the housing elements to be suitably connected to one another and to support frame 7 in the manner described above.
  • the modified housing elements 52 and 53 may advantageously be formed of a plastics material by a die-forming or thermoforming process.
  • 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.
  • a further-advantage of this type of a laundry washing machine consists in that the functionaloan components thereof are readily accessible after dismounting the housing elements from the support frame, so that repair and maintenance wcrk as well as the replacement of any of the components are greatly facilitated.
  • the support frame is the only structural member to perform a carrying function, lateral vibrations of the machine are practically eliminated.
  • 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.
  • 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.
  • 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.
