DETAILED DESCRIPTION
(12) In the example shown in
(13) By way of non-limiting example, the cavity 24 presents a shape that is substantially cylindrical.
(14) By way of non-limiting example, the enclosure 20 includes an opening 30 formed in its top end together with a lid 32 shaped to cover the opening 30 so as to close the cavity 24.
(15) The enclosure 20 also has closure means 34 configured to hold the lid 32 against the opening 30. In the example shown in
(16) The wall 22 of the enclosure 20 includes a peripheral partition 26 and a bottom 28.
(17) In the example shown in
(18) The enclosure 20 of the citrus juicer 100 of the present disclosure is thus configured so that its cavity 24 can receive produce 10 for pressing such as an orange, a lemon, any other fruit or vegetable, said produce for pressing containing a fluid.
(19) By way of non-limiting example, the citrus juicer 100 also has a cannula 50 extending through the bottom 28 of the wall 22.
(20) The cannula 50 has a longitudinal axis L; by way of non-limiting example, the longitudinal axis L of the cannula 50 extends substantially parallel to the axis of the cylindrical shape defined by the cavity 24. Preferably, the axes coincide.
(21) Furthermore, the cannula 50 has first and second longitudinal portions 52 and 54, the first portion 52 being arranged inside the cavity 24 and configured to be engaged in the produce for processing 10 when the produce for pressing is arranged in the cavity 24. The second portion 54 of the cannula 50 is arranged outside the cavity 24.
(22) The cannula 50 also has a through opening 58 comprising an internal duct extending in the first and second longitudinal portions 52 and 54, for a purpose that is described more clearly below.
(23) The citrus juicer 100 also has an extensible membrane 80 arranged inside the cavity 24 and extending over the wall 22 in such a manner as to surround the produce for pressing 10 when it is arranged in the cavity 24.
(24) The extensible membrane 80 comprises a body 82 of shape that is substantially cylindrical, by way of non-limiting example.
(25) The extensible membrane 80 also has inflatable portions 84, 84′ that may either be joined to each other in order to form a single inflatable portion or else be distinct from each other and separated so that they are not in fluid flow communication with each other. Without going beyond the ambit of the present disclosure, it is possible to devise a citrus juicer in which the extensible membrane has more than two inflatable portions, potentially in fluid flow communication with one another.
(26) The citrus juicer 100 also includes inflation means 90 configured to inflate the extensible membrane 80.
(27) The extensible membrane 80 of the citrus juicer 100 of the present disclosure can thus take on a deflated state, as shown in
(28) The inflation means 90 are configured to introduce any type of fluid into the extensible membrane 80, such as air or water. The inflation means 90 are connected to a fluid source, such as a source of gas or a source of water; it is also possible to devise a citrus juicer 100 in which the extensible membrane is inflated by mouth by the user or from any other fluid source.
(29) The inflatable portions 84, 84′ of the extensible membrane 80 extend over the peripheral partition 26 of the wall 22.
(30) The citrus juicer 100 of the present disclosure is thus configured to enable the fluid contained in the produce for pressing 10 to be extracted.
(31) To do this, the lid 32 is initially removed, as shown in
(32) When it is arranged inside the cavity 24, the produce for pressing 10 is surrounded by the extensible membrane 80, as shown in particular in
(33) While the produce for pressing 10 is being introduced into the cavity 24, the produce for pressing 10 is engaged on the first portion 52 of the cannula 50 so that a portion of the cannula 50 extends inside the produce for pressing 10, as shown in
(34) Thereafter, the lid 32 is positioned to cover the opening 30. Closure means 34 are then actuated to hold the lid 32 on the opening 30.
(35) Thereafter, the inflation means 90 are actuated to introduce fluid into the extensible membrane 80 so as to cause it to pass from the deflated or partially inflated state to the inflated state; the inflatable portions 84 and 84′ of the extensible membrane 80 then compress the produce for pressing 10, as shown in
(36) By way of non-limiting example, the lid 32 presents blocking means fastened on its inside surface in order to contribute to holding the produce for pressing 10 inside the volume defined by the extensible membrane 80.
(37) The fluid contained in the produce for pressing 10 is then directed towards the first portion 52 of the cannula 50 and subsequently flows into the internal duct 58 until it reaches the second portion 54 of the cannula 50.
(38) It can thus be understood that the increase in the volume of the extensible membrane 80 as a result of actuating the inflation means 90 serves to compress the produce for pressing 10 in order to extract a significant portion of the fluid it contains, or indeed all of it; by way of non-limiting example, the citrus juicer 100 of the present disclosure enables more than 40% of the fluid contained by the produce for pressing 10 to be extracted, preferably more than 60%, more preferably more than 80%, the fluid then being recovered outside the cavity 24 in the proximity of the second portion 54 of the cannula 50.
(39) In the example shown in particular in
(40) After the produce for pressing 10 has been compressed in order to extract fluid therefrom, the closure means 34 are actuated so as to enable the lid 32 to be removed from the opening 30 in order to extract the produce for pressing 10 from the cavity 24, which produce is now emptied of a significant portion of the fluid that it contained.
(41) As shown in the various figures, the citrus juicer 100 of the present disclosure also has fluid admission means 92 for admitting a fluid, such as water, into the cavity 24. By way of non-limiting example, the fluid admission means 92 comprise through openings formed in the lid 32.
(42) Thus, after the produce for pressing 10 has been removed from the cavity 24, a fluid, such as water, is introduced into the cavity 24 in order to clean it. In order to avoid soiling the space surrounding the citrus juicer 100, the fluid admission means 92 may be capable of being actuated only once the lid 32 closes the opening 30 of the enclosure 20.
(43) The citrus juicer 100 may optionally include an ultrasound emitter device 94 configured to emit ultrasound into the fluid that has been introduced into the cavity 24 by the fluid admission means 92, so as to contribute to cleaning said cavity 24.
(44) By way of non-limiting example, the citrus juicer 100 also has rotation means 96 configured to cause the cannula 50 to rotate about its longitudinal axis L; the rotation means 96 thus facilitate engaging the produce for pressing 10 on the first portion 52 of the cannula 50 while it is being introduced into the cavity 24, so as to facilitate extracting fluid therefrom.
(45) The citrus juicer 100 also has a support 40, specifically a tripod, extending from the bottom 28 of the wall 22 so as to facilitate stable installation and use of the citrus juicer 100.
(46) As shown in particular in
(47)
(48) In the example shown in
(49) The cannula 50′ also has engagement blades 58′ extending from the annular abutment 59′ along the outside surface 56′; the engagement blades 58′, which constitute projections, thus facilitate engaging the produce for pressing 10 on the cannula 50′, and also facilitate extracting fluid, by cutting through the flesh of the produce for pressing 10.
(50) In addition, the cannula 50′ has windows 60′ configured to allow the fluid contained in the produce for pressing 10 to flow into the internal duct of the cannula 50′.
(51) In the example shown in
(52) The cannula 50″ also has engagement blades 58″, which constitute projections, extending along the outside surface 56″ serving to facilitate engagement of the produce for pressing and extraction of its fluid; the cannula 50″ also has a perforated portion 60″ arranged between the first portion 52″ and the annular abutment 59″ to allow the fluid extracted from the produce for pressing 10 to flow into the internal duct of the cannula 50″.
(53) In the example shown in
(54) In addition, the cannula 50′″ has openings 63′″ opening out into the internal duct to enable the fluid to be extracted from the produce for pressing 10.
(55)
(56) In similar manner to the other embodiments, the citrus juicer 100 has an enclosure 20, e.g. of substantially cylindrical shape, having a wall 22 defining a cavity 24, the enclosure 20 also having an opening 30 to enable produce for pressing 10 to be introduced into the cavity 24.
(57) This citrus juicer also has a cannula 50 with a first portion 52 arranged inside the enclosure and a second portion 54 arranged outside the enclosure, underneath it. The first and second portions include an internal duct 39 for discharging the juice that is extracted from the produce for pressing 10 outside the enclosure. The cannula also has orifices 37, shown in
(58) Furthermore, the cannula 50 shown in
(59) The first portion 52 of the cannula comprises a body 52b that extends between a base 52c and the bullet-shaped top end 52a, the body having orifices 37.
(60) It can be understood that this shape serves to maximize the contact area between the cannula and the produce for pressing.
(61) The body comprises a cylindrical cage 49 comprising a plurality of axial rods 51 that are spaced apart from one another, the rods extending over substantially the entire height of the cavity.
(62) The citrus juicer 100 also has a movable lid 32 that can either occupy an open position, as shown in
(63) In the closed position, the top end 52a of the cannula is engaged in a setback 32a arranged in the lid. It can thus be understood that the cannula passes axially through the pressed produce. This serves to maximize the working area between the cannula and the produce for pressing, thereby serving to improve the effectiveness with which juice is extracted.
(64) The citrus juicer 100 also has an ejector device 31 for discharging the pressed produce out from the cavity after the juice has been extracted. The ejector device 31 has a movable base 33 configured to receive a bottom portion of the produce for pressing 10. The movable base 33 is movable along the longitudinal axis L of the cannula. The movable base has an annular tray 35 arranged to surround the cannula. The annular tray is thus movable longitudinally along the cannula. While extracting juice, the annular tray 35 is arranged at the bottom of the cavity. As shown in
(65) With reference to
(66) The movable base 35 also has the function of guiding movement and engagement on the cannula 50. It can thus be understood that the movable base 33 and the movable lid 32 are moved in substantially synchronized manner so as to move the produce for pressing 10 towards the cavity 24 while pushing on the produce for pressing so that it becomes engaged on the cannula 50.
(67) The citrus juicer 100 also has an introduction device 102 configured to enable the produce for pressing 10 to be introduced into the cavity.
(68) By way of non-limiting example, the introduction device 102 comprises a hopper that is mounted to pivot about an axis, e.g. and in non-limiting manner, an axis that is substantially horizontal. The introduction device 102 can thus occupy a pick-up position as shown in
(69) As explained above, the movable lid 32 is configured to make it possible, while it is moving from its open position to its closed position, to engage the produce for pressing 10 on the cannula 50. For this purpose, the lid 32 delivers downward vertical thrust on the produce for pressing, which then becomes engaged on the first portion of the cannula. The lid then closes the enclosure and the annular tray is to be found at the bottom of the cavity.
(70) The citrus juicer also has a locking system 57 for closing the enclosure during the operation of inflating the extensible membrane 80. In this example, the locking system comprises catches 41 that take up positions above a collar 32b of the lid when the lid is in its closed position.
(71) The cannula extends substantially parallel relative to the axis of the cylindrical shape defined by the cavity 24 so as to facilitate subsequent extraction of its fluid.
(72) Furthermore, in similar manner to the above-described embodiments, the citrus juicer 100 has an extensible membrane 80 arranged in the cavity 24 and extending over the wall 22 so as to surround the produce for pressing 10.
(73) By way of non-limiting example, the extensible membrane 80 has first and second extensible portions 85 and 85′ fastened to the wall 22 so as to define a volume between the wall 22 and said first and second extensible portions 85 and 85′; the citrus juicer 100 also has inflation means 90, e.g. comprising, in non-limiting manner, a compressor 91 for enabling fluid to be introduced into said volume so as to move the first and second extensible portions 85 and 85′ to compress the produce for pressing 10 that is arranged inside the cavity 24 so as to extract fluid therefrom via the cannula 50, as can be seen in particular in
(74) The citrus juicer also has a mover device (not shown) for moving both the lid 32 and the annular tray of the movable base 33 of the ejector device together in a direction parallel to the longitudinal axis L of the cannula. The mover device is motor-driven by a gearmotor associated with a wormscrew. It thus serves to enable engagement of the produce for pressing on the cannula to be automated, and also its ejection from the enclosure.
(75) The mover device is configured so that the movable base 33 is arranged at the bottom of the cavity when the lid is in the closed position, while the movable base is arranged at or above the opening 30 when the lid is in the open position.
(76) After extracting fluid, the mover device is actuated so as to bring the lid into the open position together with the ejector device into the reception position, thereby having the effect of ejecting the pressed produce out from the enclosure.
(77) The citrus juicer also has a discharge outlet 104 for the pressed produce 10′ and a discharge device 106 for discharging the pressed produce 10′ to the discharge outlet after being pressed.
(78) Furthermore, as shown in
(79) In order to discharge the pressed produce 10′ to the container 108, the discharge device 106 has an arm 110 arranged to pivot between a first position and a second position.
(80) As shown in
(81) The above description is given by way of example, and is therefore not limiting on the disclosure.
(82) In particular, although particularly adapted to the field of extracting juice from fruits or vegetables, the disclosure can equally well be used for extracting the fluid contained in any other type of produce in effective and accurate manner.
(83) Even though some features, concepts or aspects of the embodiments may be described herein as being a preferred (more or less) arrangement or method, or an advantageous arrangement or method, such description is not intended to suggest that such feature or features are required or necessary unless expressly so stated.
