Definitions

  • the present invention relates to a juice extractor. More particularly, it relates to a juice extractor of the kind comprising a basic unit, including a stationary juice collecting bowl, provided with an outlet for collected juice at a lower portion thereof, and a driving shaft which is mounted for rotary movement and limited axial displacement in said basic unit and extends in an approximately vertical direction through an opening in the bottom of the collecting bowl and which comprises an upper portion, projecting into the collecting bowl to carry a juice extraction means removably mounted on the driving shaft for rota ⁇ tion by means of said shaft, and a lower portion, located below the collecting bowl and arranged for releasable driving connection to an electric driving motor through a friction coupling, the driving shaft being spring-loaded towards an upper end position in which it is disconnected from the driving motor, but from which it may be resiliently depressed to a lower end position in which it is drivingly connected to the driving motor.
  • juice extractors are previously known, wherein the juice extraction means consists of a gene ⁇ rally conical squeezer head and a surrounding strainer bowl, joined to the squeezer head at the lower end of the latter. These known juice extractors are intended to be used for the extraction of juice from oranges, lemons and other citrous fruits.
  • the driving shaft is spring-loaded towards its upper end position in which it is disconnected from the driving motor, said motor may impart a rotary movement to the squeezer head and the strainer bowl only when, as a result of a downward force of sufficient magnitude, applied on the squeezer head via a citrous fruit half, placed thereon, either directly by hand or by means of a pressure cup carried by a manually operated lever, the driving shaft is caused to move to its lower end position, hereby establishing a driving connection with the driving motor.
  • the invention has for its object to provide an improved juice extractor of the kind initially specified, offering a favourable solution of the above- mentioned problem and permitting an easy and rapid conversion of the juice extractor from a citrous fruit squeezer to a raw juice centrifuge, or conversely, whenever so desired.
  • a juice extractor of said kind primarily characterized in that it further comprises a depression means which forms part of a supplementary equipment, adapted to be releasably attached to the basic unit, and which is arranged to be applied against the upper portion of the driving shaft to hold said shaft permanently depressed in its lower end position.
  • the juice extrac- tion means may rotate continously as long as the driving motor is operating need not involve any risk of physical injury, since the rotary grater disc forming part of said means may be covererd by en upper lid of the supplementary equipment. Additionally, the feed passage extending through said lid may have sufficient length and sufficiently small area to prevent a user from putting his fingers into contact with the grater disc through said passage.
  • the depression means may preferably form part of a separate adapter, comprising a generally tubular stationary body, adapted to be releasably mounted on a support, projecting into the collecting bowl around the driving shaft, and a rotary member, rotatably mounted in said body and serving as a rotary holder for said depression means.
  • the depression means may be mounted axially adjustable in said rotary adapter member in order to facilitate any required adjustment of its axial position in the rotary adapter member to ensure that the driving shaft will be forced to assume its lower end position, whenever the adapter is attached to the basic unit of the juice extractor.
  • the depression means may be mounted for limited axial displacement in said rotary adapter member and be arranged to be spring- loaded towards its lower end position.
  • the depression means may then preferably be spring-loaded from a spring, included in the adapter.
  • the spring-load applied on the depression means should have sufficient magnitude to overcome the spring-load applied on the driving shaft and tending to hold said shaft in its upper end position.
  • the rotary adapter member may pre- ferably be arranged to act as an extension of the driving shaft, adapted to rotate in unison with said shaft and serving to connect the driving shaft to a rotary juice extraction means.
  • the juice ex- traction means utilized when using the juice extractor as a raw juice centrifuge may be mounted on a sub ⁇ stantially higher level than otherwise possible.
  • Said juice extraction means may then have a diameter sub ⁇ stantially larger than the inner diameter of the juice collecting bowl, at least along a considerable portion of its length.
  • the rotary adapter member may suitably be rotatably mounted in the body of the adapter by bearing means, arranged to transmit radial deflec ⁇ tion forces, applied on said member, to the body of the adapter.
  • bearing means may preferably comprise two axially spaced bearings.
  • Figure 1 shows a diagrammatic, partially exploded perspective view of a basic unit of said juice extractor and a supplementary equipment facilitating use of the extractor as a citrous fruit squeezer.
  • Figure 2 shows a corresponding diagrammatic, partially exploded perspective view of the basic unit and a supplementary equipment facilitating use of the extractor as a raw juice centrifuge
  • Figure 3 shows a sectional side elevation view of the basic unit

  • Figure 6 shows an axial section through an adapter of slightly modified construction
  • FIG. 7 shows a partial view, in axial section, of the upper end portion of the basic unit with the supplementary equipment of Figure 2 mounted thereon.
  • the illustrated juice extractor comprises a basic unit, generally designated 10. As may best be seen from Figure 3, this basic unit comprises a body consisting of a lower portion 11, a middle portion

  • the upward force applied on driving shaft 29 from spring 38 is considerably higher than the downward force on said shaft caused by the weight of juice extraction means 42.
  • Driving shaft 29 will therefore remain in its upper end position even when extraction means 42 has been mounted thereon.
  • pressure cup 45 is attached to a mounting 49 at the lower side of a lid 50, carried by a lever 51 having its one end pivotally connected to upper portion 13 of the body of basic unit 10 by means of a pivot pin 52 ( Figure 3) and being provided with a handle 53 at its other end.
