The invention relates to a highly reliable juice extractor according to the features of the preamble part
of claim 1.
An extractor of this kind is known from FR-A-1
164 016. The known device is disadventageous in
that the cable supplying the extractor with electrical
power is troublesome and inconvenient.
DE-U-7 537 823 discloses an extractor with a
cylindrical central body and a base below the body to
which a support stand is attached.
The object of the invention is to provide an extractor according to the preamble part of claim 1 which
avoids disturbances caused by the power supply
cable and which can be correctly fixed to the surface.
This object is accomplished by the features of the
characterizing part of claim 1.
Particular embodiments or the invention are set
in
out dependent claims 2 to 11.
The aforementioned juice extractor is composed
of a cylindrical central body, obtained by means of extrusion, this being a method widely used in modern
practice, offering remarkable qualities concerning finish and neat presentation, without the need for subsequent operations ; thin walls are achieved by
means of this process, thus saving on material, without detracting from its intrinsic quality in any way. This
has obvious advantages over commonly used
methods, such as the classic sand-casting process, in
which the surfaces have to be subsequently mechansed for essential refining.
The electric motor activating the extractor is
situated inside the central body referred to above,
which also includes the appropriate sealing lid, with its
:ylindrical structure, that acts as the lower base of this
:entral body, and into which is screwed the stand supsorting the whole appliance forming the subject of this
lescription. This stand is composed of a single part
supped at the centre, providing two heights with preietermined functions : the upper part which is fixed to
he lower part of the extractor beneath the aforemenioned lid, allowing the cable to be wound up so that
t occupies less space but may expand as necessary;
ind the lower area, which should serve as support
md anchorage for the whole unit, with the appropriate
itops or flexible sheet of rubber or similar material on
he bottom of this base to stop it from sliding and to
insure that is is correctly fixed to the appropriate surace.
Logically, in the upper part of this central body
here is a sealing lid which is circular at the bottom and
las a hole at the centre for the driving shaft. This hole
s supplied with the necessary means of watertight
idjustment or stops designed to prevent liquids or
ampness from entering, thus protecting the electric
lotor and, consequently, giving it longer life. This lid
s provided with rods or projecting studs on its lower

surface inside, which are positioned almost contiguous to the side. These are threaded inside so as to
allow the fixing screws of the motor to be inserted. On
the upper surface of the aforementioned lid there is a
series of blind holes for fixing the centring stubs of the
extractor head, the body of which is formed by two
superimposed parts fitted together under pressure,
with the lower part having a semi-spherical cross-section, supplied with an outlet at the bottom for the exit
of the liquid or juice extracted, made of a short length
of tubing to which is fitted the conduction pipe of the
aforementioned juice, set at a downward angle with
an elbowed pipe at its free end to allow the liquid to
flow out vertically.
Another similar part with the same exterior shape
is fitted upside-down to the upper end of this lower
part ; sloping it towards the interior allows it to be fitted
without protruding outside. In the upper part of this
complementary body there is a horizontal edge
flanged towards the interior, which makes a wide circular inlet through which the product to be squeezed
is introduced.
The aforementioned shaft is screwed on to
another end shaft optionally fitted with a hexagonal
rod, on top of which is located the extracting cone,
manufactured with convex outer walls and rounded
apex finished in a stub or upper appendage designed
to provide better centring of the product referred to ;
this cone has the appropriate longitudinal grooves to
facilitate squeezing, while its base, formed by a horizontal flange, joins the squeezing cone to the filtering
or straining component, which is composed of an
open receptacle at the bottom, optionally cylindrical in
shape, with the side and bottom walls thus being provided with a suitable grille or filter through which only
the squeezed juice may pass, with the non-usable
pulp remaining inside. This filter is capable of turning
together with the aforementioned extracting cone,
thus allowing for centrifugal filtering and, in this way,
making the essential action of extracting liquids faster
and more efficient
Furthermore, the extractor concerned in this
invention has an auxiliary arm which enables the function described to be accelerated by exerting pressure
on the product in question. The fixed part of this arm
is screwed to the upper base of the central cylindrical
body ; it is slightly curved in shape, lying close to the
upper body, and has a joint at an intermediate point
with this body, from which protrudes the mobile lever
for accelerating the extracting process. This is composed of a rectangular body with a longitudinal shape
following the upper contours of the extractor, and ending in a slight bend near the free end, forming a handle
for working the lever of the arm.
The arm thus defined has a switch below the joint,
activated by means of a cam situated at the lower end
of the lever. This is activated when lowered and disactivated when raised and there is no contact bet-
J
=P 0 226 691 B1
ween the cam and the switch.
Screwed to the horizontal part of the lever of the
aforementioned activating arm is a circular lid designed to cover the hole or outlet of the upper area of the
extracting device, there being a concentric cap
beneath this lid adaptable to the extracting cone, with
which pressure is exerted on the product by working
the lever referred to above, so as to bring this close
to the aforementioned cone, and therefore achieve
greater effectiveness.
Electricity is supplied by means of a main switch,
preferably situated near the base of the extractor proposed ; this mechanism is complemented by the
switch referred to above, located beneath the joint of
the lever arm.
Both the anchoring of the arm referred to and that
of other parts that need to be secured, is accomplished by means of screws of the same model and
bore, so as to allow the appliance to be assembled
and disassembled easily and quickly with the same
spanner.
In a simplified version of the extractor described,
it is not necessary to install the lever arm and its
accessories, the filtering component being substituted by another simpler part along with a microswitch which is worked by exerting pressure on the
extracting cone.
The aforementioned filtering or straining component is fitted under pressure inside the upper body. It
may be easily removed for cleaning and is adaptable
in form to the internal process of this extractor body,
in such a way that all the juice obtained falls on to the
strainer or filter, the base of which coincides with the
duct leading to the exit through the elbowed pipe mentioned previously.
The extracting cone is removed, in either case, by
pulling it up to uncouple it from the hexagonal rod, so
as to facilitate cleaning.
The rod activating the extractor may be the drivitself or, on the other hand, be formed by this
shaft
ing
shaft and a body surrounding it axially, separated by
an internal spring, the pressure of which is broken by
pressing on the extracting cone, which makes the
aforementioned body move down until a horizontal
ring-shaped end comes into contact with the microswitch which works the motor.
The following detailed description refers to the
accompanying illustrations in which one may of carrying out the invention is described.
Figure 1 represents a vertical section through the
middle of the extractor including the lever arm.

Figure 1 shows firstly the central cylindrical body
-1- inside which is located the electric motor -2activating the extractor and below this, the general
supply switch -3- which connects or disconnects the
appliance from the mains. On the base of the central
cylindrical body the lid -4- can be seen to which is
fixed the base or stand by means of a screw and nut
-5-. This base or stand is formed by a cylindrical plate
cupped at the centre in such a way that this base comprises a body of two heights : the upper or central one
-6- and the lower one -7- which togetherwith their corresponding anti-sliding bases -8- stabilize the whole
unit. This plate is diametrically mortised to house the
supply cable when wound up, so that this does not
protrude outside, and allows it to be extended adequately as required by the moment and the position of
the extractor, adjusting to the distance required.
As a sealing component for the central body -1the appliance is supplied with a graded lid -10- with a
central hole -11- through which emerges the driving
shaft, with the corresponding sealing stop -12- being
provided for its adjustment to this hole for the purpose
mentioned above. Inside this lid on its lower surface
there are some rods or studs -13- which are threaded
inside for fitting the fixing or anchoring screws of the
motor. On the upper surface of the lid of the motor, at
an intermediate point are situated the centring holes
-14- over which are fitted the centring appendages 15- of the upper body -16- which is supplied with a
hole -17- on its lower edge, for the exit of the liquid.
Into this hole is inserted the pipe -18- under pressure
which is conveniently elbowed at its free end -19- so
as to allow the juice obtained to flow out vertically. To
the aforementioned body -16- is fitted underpressure,
another similar superimposed body -20- with grading
-21- on its lower edge towards the interior, and suitable for inserting in the aforementioned body -16-.
This upper body has a horizontal section along its
upper edge -22- finished off with an inwardly curving
flange -23- marking a wide circular inlet through which
the product to be squeezed is introduced.
The squeezing mechanism is situated inside the
extractor and is connected to the driving shaft by
means of a complementary rod with hexagonal head
- 24 - to which is fitted the extractor head itself -25with the shape described above and protuberance 26- such that the fruit to be squeezed may be centred
more efficiently. On the walls of this head there are
grooves designed to carry out their appropriate function and a horizontal flap -27- for anchorage to the filtering component -28-. This is composed of a
cylindrical receptacle joined to the extracting cone,
with holes on its side walls allowing the centrifugal
passage of the juice obtained, while at the same time
retaining the surplus pulp.
A side arm is supplied as an accessory to the extractor formed by a fixed body -29- connected to the
lid -10- mentioned above, by means of screws, on
EP 0 226 691 B1
wnicn tne rest or me arm is articulated as a lever -30with a downward bend near its free end forming a handle -31- to make it easier to manipulate this lever.
A circular sealing lid -32- is fitted to the interior
surface of the lever arm, also by means of screws, and
below this there is a cap -33- which exerts pressure
on the product to be squeezed in such a way that this
task is made easier since the extracting component 25- may be adjusted in shape by exerting pressure on
the lever arm.
There is a micro-switch -34- on the fixed arm -29designed to activate the motor and provided with a
push button worked by the cam -35- of the lever arm
-30-.
Figure 2 shows a detail of the anchorage of the
fixed part -29- of the arm crossed by the hole -36- in
the body -1- and connected to the upper sealing lid 10- by means of screws designed for this purpose,
described with their bench mark -37-.
Figure 3 provides us with a view from the bottom
of the aforementioned anchorage shown in detail in
the previous figure, indicating the bench marks -29and -37- referred to above.
In the simplified version illustrated in figure 4, in
addition to the common details indicated with bench
marks -1- to -28-, one can see the ring-shaped flange
•38- contacting the micro-switch -39-, the hole -40- for
:oupling the driving shaft -41- between which is
riwardly situated the helicoidal spring -42- which
allows the axle of the extracting cone to recover once
pressure is removed by disconnecting the microswitch. This micro-switch may also be eliminated in
such a way that the shaft -24- will be composed of one
jr several concentric parts that transmit theirmovenent directly to the extracting cone -25- when the
nain switch is activated -3- as wished.
Having adequately described the object of the
)resent invention, it should be pointed out that a great
nany variations in detail enjoying the same protection
nay be added to the essential features of the
ippliance, with these possibly affecting the unit itself
>r its parts as well as the components selected and
he means for producing the system designed.
