Definitions

  • the present invention relates to a domestic washing machine, in particular a laundry washing machine, comprising a cabinet having at least three vertical walls in metal plate.
  • a cabinet such as the type mentioned, comprising in particular a frontal wall, two lateral sides and a rear wall.
  • the welding operations are relatively simple, but it is necessary to equip the cabinet with appropriate reinforcements, that have to be obtained and fixed separately, with additional operations; with the second mentioned strengthening technique the reinforcements of the structure are directly obtainable from the metal plate that constitutes the walls of the cabinet, in a relatively simple way with the use of automatic machinery: the operations of welding the corners does however require particular attention (for instance as the lower reinforcement profiles are of a box like form, as a U, and the metal plate that constitutes such reinforcements is lapped over itself).
  • the aim of the present invention is that of indicating a strengthening method for three vertical walls of the cabinet of a laundry washing machine, which avoids the necessity of utilising additional pieces and in which the welding operations are simple to carry out and of a limited number.
  • a domestic washing machine in particular a laundry washing machine
  • a cabinet having at least three vertical walls in metal plate, characterised in that each of said three vertical walls is strengthened on at least one extremity, in particular the lower, with a multiple bent shaping, in particular more than five bends, and at least one part of the shaping of one of said walls is crossed, in particular overlapped, with a part of the shaping of the wall to which it is perpendicular.
  • the superior part represents the vertical section (A) of the lower part of a lateral wall of the cabinet of the machine, while the lower part represents the vertical section (B) of the lower part of the frontal wall of the cabinet of the machine.
  • letter L indicates the lateral wall;
  • reference number 1 indicates a first portion of the lateral wall L horizontally bent; to said portion 1 a second vertically bent portion follows, parallel to the lateral wall L; to this second portion there follows a third (2), that has a horizontal stretch, and that also has two lateral holes, one of which is indicated with reference number 3.
  • letter F indicates the frontal part of the cabinet of the machine; reference number 6 indicates a first portion of the frontal wall F horizontally bent; to said first portion 6 a second vertically bent portion follows, parallel to the frontal wall F; to this second portion there follows a third (7), that has a horizontal stretch, and that also has two lateral holes, one of which is indicated with number 10.
  • the assembly of the frontal wall F and of the lateral walls L is obtained from a single sheet of plate metal, that has a development in height being greater than the height that the three mentioned walls of the cabinet of the machine will have.
  • Said sheet of plate metal is passed through appropriate machines, that carry out the various 90° bends at one of the extremities of the sheet; the same machines carry out the necessary holes and trimming, for instance in correspondence with the points in which the sheet of plate metal is to be bent at right angles for forming the frontal corners of the cabinet.
  • the sheet of plate metal is therefore bent to a "C" shape, for obtaining the frontal wall-lateral wall assembly;
  • figure 2 in fact illustrates a plan view of one of the two corners that are formed between the frontal wall F and the lateral walls L in following the bending to a "C".
  • the holes 10 of the frontal wall serve for the assembling of eventual feet; a threaded nut can be welded or braced above part 7 and within which the stem of the foot can be screwed, realising a support being adjustable in height; the holes 3 of the lateral walls are realised for allowing the passage of the threaded stem of the foot (there are also another two holes (3) in the rear part of each of the lateral walls L, that will be used for fixing another two adjustable feet).
  • the described strengthening method could be further advantageously utilised for reinforcing and joining, by way of 90° bends, overlapping of pieces, and simple points of welding, the superior parts of the frontal wall (or rear) and of the lateral walls; in this way the cabinet of the laundry washing machine could also be obtained also eliminating the superior reinforcing cross members, normally provided in several types of washing machine.
