Definitions

  • the present invention relates to electric household appliances for cutting fruit, vegetables and similar food products into small sticks or chunks of variable-thickness, comprising the features of the pre-characterising portion of the main claim.
  • the invention concerns an electric household appliance of the so-called multi-function type in that it can use different implements, tools or devices for performing corresponding functions such as, for example, mincing, slicing, cutting squeezing, centrifuging, blending and the like.
  • a tool which, in most cases, comprises a plurality of blades fixed to the disc (or associated with the disc) and projecting from one face thereof, the blades being aligned radially on this face.
  • Each blade has an essentially right-angled shape, with a portion perpendicular to the disc and a portion substantially parallel thereto. The blade portions perpendicular to the disc cut the product into strips, while the blade portions parallel to the disc further cut the strips as they are produced.
  • the transverse dimensions of the small sticks or chunks of product obtained are determined by the length of the blade portions perpendicular to the disc and by the mutual spacing in their radial alignment on the disc.
  • the technical problem which it is intended to solve by this invention is that of providing an electric household appliance of the type under consideration, having structural and functional characteristics such as to overcome the disadvantage cited above with reference to the prior art.
  • a particular embodiment of the invention includes a slicing blade which projects laterally and radially with respect to a hub and is fixed coaxially for rotation with the motor-driven shaft, the slicing blade being substantially complanar with the end of the hopper-duct and rotating edgewise thereto.
  • the disc with the slots through which the blades of the cutting tool pass is adjustably positioned between the cutting tool and the slicing blade.
  • an electric household appliance comprises a box-like body 1 with one part 2 which is intended to receive a drive unit and its accessories, not shown since they are entirely conventional, and is alongside an essentially base providing support part 3.
  • a substantially cylindrical projection 5 In the centre of the upper wall 4 of the base 3 is a substantially cylindrical projection 5 having an axial through-hole 6.
  • a motor-driven shaft 7 is rotatably supported in the hole with the interposition of bearings, schematically indicated 8.
  • a container 9 is intended to rest on the base 3 and has a bottom 10 provided centrally with a tubular part 11 which extends axially inwardly of the container itself.
  • the tubular portion 11 coaxially surrounds the motor-driven shaft 7 which thus extends axially within the container.
  • the container 9 can be closed by means of a lid 12 formed with a duct 13 which, when the lid is fitted on the container 9, extends eccentrically relative to the motor-driven shaft 7 and has an end 14 which opens into the container 9.
  • the duct 13 is used for passing fruit, vegetables or similar food products which are to be cut into small sticks or chunks into the container 9. For this reason, the duct 13 will be called the hopper-duct in the following description and in the subsequent claims.
  • a shaft 15 having an axial through-hole is fitted axially onto the portion of the motor-driven shaft 7 which project from the base 3, and is fixed for rotation with the motor-driven shaft, for example, by means of a splined coupling 16 or other similar coupling.
  • the shaft 15 has an upper portion 17 extending into the container 9 above the tubular portion 11 thereof.
  • a disc 25 ( Figures 4 and 5), also preferably of synthetic, atoxic plastics material, is provided at its centre with a tubular hub 26 by means of which the disc 25 is fixed coaxially for rotation to the portion 17 of the shaft 15 in a position between a cutting tool 42 and the open end 14 of the hopper-duct 13.
  • the disc 25 can also be adjusted in its position along the axis of rotation of the shaft 15.
  • the hub 26 of the disc 25 is mounted on the portion 17 of the shaft 15 by means of a splined coupling, schematically indicated 27.
  • the hub 26 of the disc 25 is engaged in a cylindrical cavity 28 formed coaxially in the upper end of the portion 17 of the shaft 15, the splined coupling being formed in the cavity.
  • the disc 25 also defines, in an appropriate position, a large shaped aperture 30 for allowing the product cut into small sticks or chunks to pass into the bottom 10 of the container 9 ( Figure 6).
  • a slicing blade 31 has an annular portion 32 constituting essentially a flattened hub by means of which the blade is fixed for rotation with the motor-driven shaft 7.
  • four columns 34 ( Figures 2 and 3) are formed or otherwise fixed to the portion 17 of the hollow shaft 15 in positions diametrally opposite each other so that they extend parallel to the axis of the portion 17 and project beyond the cylindrical cavity 28 formed therein. It should be noted that the small columns 34 also pass beyond the disc 25 through four corresponding apertures 35 formed therein ( Figure 4).
  • the flattened hub 32 of the slicing blade 31 is fixed to the upper ends of the columns 34, for example, by means of screws schematically indicated 33. ( Figure 6).
  • the slicing blade 31 extends so as to be coplanar with the open end 14 of the hopper-duct 13 and rotates edgewise thereto.
  • a cutting tool 42 ( Figure 7) comprises a plurality of blades each indicated 43, fixed onto an arm 44. More particularly ( Figure 6) the blades 43 are located along a curved line with a profile substantially the same as the cutting profile of the slicing blade 31, which is a profile substantially in the form of a portion of a spiral with the convex side facing in the direction of rotation. Thus, the blades 43 come into contact with the product to be cut one after the other and avoid exerting a tearing effect on the product, which could occur if all the blades of a cutting tool contact the product simultaneously.
  • the disc 25 ( Figure 6) will have a line of slots 46 corresponding to the blades 43 of the cutting tool 42.
  • the arm 44 is fixed so that it projects laterally from, or is formed in one piece with, a hollow hub 45 from which the arm 44 extends radially.
  • a radial pin 22 On the inner wall of the hub 45 is formed or otherwise fixed a radial pin 22 by means of which the hub may be fixed coaxially and releasably by bayonet engagement to the upper portion 17 of the shaft 15, with which it is thus locked for rotation.
  • the coupling between the hub 45 and the shaft 15 may be achieved by other means entirely equivalent to bayonet engagement, which are well known in this branch of the art.
  • the arm 44 is spaced from the end 14 of the hopper-duct 13 which opens into the container 9 by a distance equal to the length of the blades 43. Consequently, the upper ends of the blades are very close to the open end 14 of the hopper-duct 13.
  • the angular position of the slicing blade 31 and the cutting tool 42 relative to the axis of rotation of the motor-driven shaft 7 is chosen so that the blades 43 of the cutting tool have an earlier impact on the product to be cut than the slicing blade 31.
  • a knob 36 rests so as to be freely rotatable on the flattened hub 32, and the upper portion 37 of a shaft, generally indicated 38, extending coaxially with the motor driven shaft 7 is fixed axially to the knob 36.
  • the shaft 38 has a lower threaded portion 39 screwed into a threaded hole 40 formed axially in a metal insert 41 embedded coaxially in the hub 26 of the disc 25.
  • Rotation of the knob 36 causes the screwing or unscrewing of the threaded portion 39 of the shaft 38 relative to the threaded hole 40 and hence causes a movement of the disc 25 along the axis of the motor-driven shaft 7. Consequently, the disc may be located at any position between the cutting device 42 and the slicing blade 31.
  • the main advantage of this invention is that of enabling the thickness of the small sticks or chunks of food product cut by the electrica appliance desribed above to be varied at will. Indeed, by operating the knob 36, one can vary the position of the disc 25 relative to the open end 14 of the hopper-duct 13 and vary the thickness of food product which projects from the hopper into the container 9 and rests or bears on the disc 25. It should be noted that the adjustment of the position of the disc 25 occurs without any adjustment of the portion of the cutting tool 42 which remains locked in its intial predetermined position on the hollow shaft 15.
  • the slicing blade 31 and the disc 25 constitute the tools for the function of slicing food products with the possibility of varying the thickness of the slices obtained. Consequently, in such a multi-function electric appliance it is possible, with only three accessories (the cutting tool 42, the disc 25 and the slicing blade 31) to carry out two basic functions: that of slicing and that of cutting into small sticks or chunks of variable thicknesses.
  • a further, not inconsiderable advantage is constituted by the fact that the aforementioned adjustable positioning of the disc 25 can be achieved by operating a knob which is readily accessible upon the simple removal of the lid 12.
