Description
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.
Through the closing system proposed in the present description for its application in the
connection of the two halves of a plastic tank for a washing machine, the time spent in
such operation and the material cost of the same is considerably reduced, which reduces
drastically the total cost of the tank.
On the other hand, the system of connection allows the fast and simple separation of both
halves and their following connection through conventional screws.
In fact, it is about to have a cheap closing system of the two halves for the plastic tank for
a washing machine, that allows the separation and following connection of the two halves
in those exceptional cases where the tank of the washing machine must be manipulated
by the service of technical assistance because of technical reasons.
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.
In this way, 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.
Conventionally the 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.
Thus, 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.
For joining the two halves of the tank relative to the open base, it is necessary to form
some radial lugs provided with some orifices for the screwing of respective screws which
establish the connection.
Also, there is a seal placed between both bodies which will guarantee an hermetic closing.
In this way, the connection between both halves is established by a set of screws, so that
one or several workers must thread the screws. For joining both halves it is necessary to
spend much time because there are approximately 17 screws.
With this configuration it has to be taken into account the necessity of the use of the cited
number of screws, with the cost that it represents and a lot of time that has to be spent in
the screwing of all of them. This represents a high cost as a consequence of the added
value of the screws that are utilised and the cost of the workers necessary to carry out the
operation of closing.
In this way, if the tank of the washing machine must be disassembled because of technical
motives, its two halves can be separated when all fixing screws are unscrewed and
later it can be assembled when the two halves that form the tank stay fixed through the
screws of connection.
In the present description 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 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.
On the other hand 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. Besides 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.
With this structure and with the introduction of the tip of the screwdriver or a similar tool, it
is allowed to flex and to separate the prolongation of the radial prolongations like an inverted
arch and the axial projection in form of tip harpoon of the other half of the tank for
causing their liberation because of the pressure exercised by the water tight seal.
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.
On the other side, in those exceptional cases where the tank must be disassembled by
the service of technical assistance, 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.
To complement the following description and to help to understand its characteristics, to
this description it is enclosed a set of drawings made up of some figures that represent in
a illustrative and not limitative way the most significant details of the invention described
in the present description.
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. Likewise,
we can observe 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.
In view of the above cited figures, and in accordance with the numbering used, we can
see how 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.
In relationship to the perimeter of the base of connection of both halves (1, 2) that form
the tank of the washing machine, one of them defines a lodging (3) where the corresponding
seal is placed. This seal is united to a projection (4) of the other half that is going to be
joined. Moreover, the two bases which are going to be joined have a set of lugs (5) -
placed over their respective perimeters - which are provided with respective orifices (6)
so that the orifices of one of the bases of connection coincide with the orifices of the other
base. In this way, the closing and fixing of the two halves of the tank will be carried out
through some screws so that each one go through both orifices.
The cost of this kind of closing goes up because of the cost of the utilised screws approximately
17 screws and the time that we have to spend in the screwing of all of them.
The closing system that is described in the present description has been thought for
solving these obstacles. Through this system, the two halves of the tank (1, 2) are provided
of the means of closing during their process of manufacture through mould. In this
way, 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, while 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.
In relationship to their upper internal side, 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).
For realising the cited connections, it will be used a press so that a single punch will produce
the simultaneous anchorage of all the axial projections (7) of the half (2) of the tank
into the corresponding orifices (9) of the radial projections (8) of the other half of the tank,
in collaboration with the projecting prolongation (10), because of the pressure that must
be realised to realise the closing, obtaining the watertight seal by means of the joint placed in
the lodging (3) and where the projection (4) of the other half of the tank tops.
As a consequence of the conjunction of the radial projections (8) and their corresponding
prolongations (10) as soon as the projecting positioning of the axial projections (7) a
lodging (12) is formed because of their connection so that if a screwdriver or a similar
element is introduced into this lodging, the separation between the projection (7) and the
prolongation (10) will be realised. In this way and because of the simple pressure exercised
by the joint, the projection (7) stays liberate so that the disassembly of both halves
is fast and simple.
The cost of the tank of the washing machine is substantially reduced with this kind of
closing because all the screws that are utilised in a conventional way for joining the two
halves of the tank are eliminated and also because of the saving of time because with this
system the simultaneous anchorage of all the elements of closing is realised with a single
punch of press.
On the other side, in those exceptional cases where the two halves must be separated by
the service of technical assistance with the described system the new closing of the two
halves will be realised because the two halves of the tanks have some lugs (5) with their
corresponding orifices (6) and for making their anchorage easy, one of the pairs of lugs
that are confronted have a polygonal orifice (13) where the head of the corresponding
screw will be inserted.
