Definitions

  • the following invention like it is expressed in the enunciation of this descriptive report, consists of a closing system in plastic tank for washing machine that is of the kind of those which are made up of two halves that are joined by their central perimeters so that the two halves of the tank can be separated. It is shaped by the service of technical assistance so it can be manipulated if there is a breakdown.
  • the closing system that is showed in the following report can be applied in the closing of the two halves of a tank for washing machine made of plastic material , so that both halves are obtained from a mould, and for their manufacture, it is not necessary to increase the complexity of the mould because the elements which materialize the union are obtained from a mould too, and they do not put up the cost of the mould or the product.
  • the two halves of the tank form its structure because of their union through their central perimeters, with the insertion of the joint of watertight, so that while the base of one of the halves is open for staying in relationship to the door of the washing machine, the base of the other half determines the back closed part that is endowed of an axial and central orifice that allows the entry of the spindle of the drum.
  • the plastic tanks of washing machines are manufactured from a mould which has two halves that when are joined, form the tank of the washing machine where the drum will be placed, so that in the manufactured of the own body of the tank, the accesory elements for its subjection and for the union among other elements are determined, so that the union between the two halves is produced, for shaping an hermetic body.
  • the two halves that shape the body of the tank are joined through their central perimeters so that the base of one of the halves is open for staying in relationship to the frontal part of the washing machine, and the other half determines the back part of the tank, having an axial central orifice that allows the entry of the spindle of the drum which is placed into the tank.
  • a closing system in plastic tank for washing machine is described.
  • This tank is formed by two halves obtained from a mould, so that the bases of both halves -those bases that are going to be joined- stay open while the second base of one of the halves of the tank determine the frontal part that remains in relationship to the door of the washing machine, and the second base of the other half determine the closed back part of the tank by an axial central orifice which allows the entry of the spindle of the drum so that the bases of union of both halves have the means of closing and fixing which coincide.
  • the means of closing of one of the two halves that form the plastic tank are determined by some axial projections, like tip of harpoon, placed in relationship to the perimeter of its base of union.
  • the means of closing of the other half of the plastic tank of the washing machine are determined by some radial cavities from the perimeter of the base of union, which have form of reversed U and they determine a rectangular orifice, so that in relationship to their upper internal side, they have a projecting prolongation which internal side determine a slope of diminishing height that is terminated of flat form, parallel to the perimeter of the tank.
  • the height of the orifice determined by the radial cavities of one of the halves that shape the tank like a reversed U is bigger than the width of the axial projections of the other half of the tank, with form of tip of harpoon, so that when the said projections intrude in their corresponding orifice stay with their external flange bumping into the free extreme of the projecting prolongation.
  • this prolongation defines a slope towards the inside that, in its union with the projection like a tip of harpoon, defines a hollow which allows the insertion of a screw or a similar tool for making its separation easy because the pressure that is exercised by the seal determines the easy separation of both halves.
  • the described form of closing let eliminate the conventional screws utilized for the closing of the two halves of the plastic tank that are obtained from a mould.
  • This form of closing represents an important saving of used material because the closing is carried out when both halves are put face to face and all the axial projections like tip of harpoon of one of the halves of the tank are introduced in the corresponding lodging of the other half of the tank, which also represents a very important saving of time of execution of the said operation.Both savings reduce the cost of industrialization of the tank in a radical way.
  • the new closing is carried out through the conventional screws because the two halves of the tank have some conventional lugs with some orifices for introducing the screws of closing and fixing, so that the anchorage of the axial projections like tip of harpoon in their corresponding lodgings, is accomplished when the screws are threaded.
  • Figure 1 shows a view in perspective of one of the utilized elements for the fixing of the two halves of the tank, showing how it has a projection terminated like a tip of harpoon -in an axial way in regard to one of the open bases of one half of the tank- while the other half of the tank has a lodging for the insertion of the cited projections.
  • the radial lugs are endowed of their respective orifices.
  • Figure 2 It shows a plan view of one of the halves of the tank whose element of union is defined by an axial projection like a tip of harpoon which proyects beyond the profile of the base of the half of the corresponding tank.
  • Figure 3 shows a plan view of the other half of the tank.An element of union is defined in relationship to this half.This element of union is formed by a lodging of rectangular section that is endowed of a projecting prolongation which is placed over its upper part so that the element of closing of the other half of the tank run into this prolongation.
  • Figure 4 It shows a plan view of the union of the two halves of the tank, so that the realization of the closing is produced through the axial projection like a tip of harpoon of one of the halves of the tank which is introduced into the lodging of the other half of the tank.
  • Figure 5 shows a sectional view, in accordance with the section I-I of the figure 2, where we can see the axial projection that is topped like a tip of harpoon for its fixing to the element of closing of the other half of the tank of the washing machine.
  • Figure 6 shows a sectional view, in accordance with the section II-II of the figure 3, where we can see the radial cavity of one half of the tank define an orifice of rectangular section that allows the pass of the corresponding axial projection of the other half of the tank, which has a projecting flange on its upper side.
  • Figure 7.-It shows a sectional view, in accordance with the section III-III of the figure 4, where we can see the form of anchorage of an element relative to both halves of the tank.In this way, we can observe there is a little hollow between the elements of closing and fixing.
  • the plastic tank of the washing machine is made up of two halves -(1) and (2)- obtained from a mould having their bases of union open, while the other base of one of them defines the frontal part of the tank which remains in relationship to the door of the washing machine, and the other base of the second half defines the back closed base of the tank, that is endowed of a central axial orifice which allows the entry of of the spindle of the drum.
  • the cavities (8) like a reversed U have a projecting prolongation (10) whose internal side defines an inclined plane at the start and it tops, in a parallel and line way, the perimeter of the tank so that, as the height of the orifice (9) defined by the cavities (8) is smaller than the width of the axial projections (7) like tip of harpoon, when these pass through the orifices (9) , the free extreme of the said prolongation (10) runs up against the extreme flange (11) of the projections (7) at the same time as the cited projections (7) stay runing up against the line stretch of the projecting prolongation (10).
