Definitions
- the following invention consists of a closing system in plastic tank for a 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.
- the closing system that is described in the following description 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 so that for their manufacture it is not necessary to increase the complexity of the mould because the elements which form the connection are obtained from a mould too, and they do not increase the cost of the mould or the products.
- the two halves of the tank form its structure when they are fixed together 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 relation to the door of the washing machine, the base of the other half determines the closed back part that is provided with an axial central orifice that allows the entry of the spindle of a drum.
- plastic tanks of washing machines are manufactured from a mould and consist of two halves that form the tank of the washing machine where the drum will be placed when they are joined, so that in the manufacturing of the own body of the tank the accessory elements for its holding and for the connection of other elements are determined, so that the connection between the two halves is established in order to form an hermetic body.
- the two halves forming 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 in the tank.
- This tank is formed by two halves obtained from a mould, so that the basis 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 form the frontal part that remains in relationship to the door of the washing machine and the second base of the other half forms the closed back part of the tank provided with an axial central orifice which allows the entry of the spindle of the drum so that the bases of connection 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 formed by some axial projections like tip of harpoon placed in relationship to the perimeter of its base of connection.
- the means of closing of the other half of the plastic tank of the washing machine are formed by some radial projections projecting from the perimeter of the base of connection, which have the form of an inverted arch and form a rectangular orifice, so that in relationship to their upper internal side they have a projecting prolongation the internal side of which forms a slope of diminishing height and has an end section with a flat form, parallel to the perimeter of the tank.
- the height of the orifice formed by the radial projections of one of the halves that shape the tank like a inverted arch 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 they stay with their external flanges bumping into the free extreme of the projection prolongation.
- this prolongation defines a slopes towards the inside that, in its connection with the projection of a tip of harpoon defines a hollow which allows the insertion of a screw driver or a similar tool in order to make its separation easier because the pressure that is exercised by the seal leads to the easy separation of both halves.
- the described form of closing lets eliminate the conventional screws utilised for the closing of the two halves of the plastic tank that are obtained from a mould.
- This form of closing represents an importing 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 orifices of the other half of the tank, which also represents a very important saving of time of execution of the set 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 projection like tip of harpoon in their corresponding lodgings, is accomplished when the screws are threaded.
- Figure 1 It shows a view in perspective of one of the utilised 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 provided with their respective orifices.
- Figure 2 It shows a plan view of one of the halves of the tank whose element of connection is defined by an axial projection like a tip of harpoon which projects beyond the profile of the base of the half of the corresponding tank.
- Figure 3 It shows a plan view of the other half of the tank.
- An element of connection is defined in relationship to this half.
- This element of connection is formed by a lodging of rectangular section that is provided with a projection prolongation which is placed over its upper part so that the element of closing the other half of the tank run into this prolongation.
- Figure 4 It shows a plan view of the connection of the two halves of the tank, so that the realisation 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 It shows a sectional view, in accordance with the section I-I of the figure 2 where it can be seen 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 It shows a sectional view, in accordance with the section II-II of the figure 3, where it can be seen the radial projection of one half of the tank which defines 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 it can be seen the form of anchorage of an element relative to both halves of the tank. In this way it can be observed that 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, 2) obtained from a mould having their bases of connection 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 of the tank, that is provided with a central axial orifice which allows the entry of the spindle of the drum.
- the two halves of the tank (1, 2) are provided of the means of closing during their process of manufacture through mould.
- one of the halves (2) of the tank has a set of axial projections like a tip of harpoon which are placed over the perimeter of its base of connection
- the other half (1) of the tank has a set of radial projections (8) like a inverted arch which are placed in a radial way over the perimeter of its base of connection.
- These radial projections (8) have respective orifice (9) that will coincide with the cited axial projections (7) of the other half.
- the radial projections (8) like a inverted arch 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 radial projections (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 running up against the line stretch of the projecting prolongation (10).
