Definitions
- Electric household appliance for shredding containers made of plastic, cardboard, tin and the like
- the present invention relates to an appliance able to shred containers made of plastic, cardboard, tin and the like.
- the object of the present invention is to provide an appliance of the type indicated above, which has a simple structure, operates in a reliable manner and also has small dimensions so that it may be easily used in a domestic environment.
- a further object of the invention is to provide an appliance of the type indicated above which is able to shred plastic waste (for example water bottles, detergent containers, etc.) and cardboard waste (for example milk cartons, cardboard used to package food, etc.) as well as tins for food and beverages, so as to facilitate the sorting of a part of household waste and ensure that separate recycling thereof is properly managed.
- the invention is based on the idea of providing an electric household appliance comprising: a cutting section including a rotating cutting tool, provided with teeth which are suitably shaped so as to be able to shred containers made of plastic, cardboard and tin, and a fixed cutting edge co-operating with the teeth of the tool ;
- a feeding section able to receive the container to be shredded and push it, crushing it, towards the cutting section; and - electric operating means able to actuate the cutting and eeding sections .
- Figure 1 is a perspective view of an electric household appliance according to a preferred embodiment of the invention, mounted on a special cabinet provided with drawers for storage of the scraps resulting from shredding of the containers;
- Figure 2 is a perspective view of the appliance of Figure 1, without the outer casing;
- Figure 3 is a cross-sectional view of the appliance of Figure 1;
- Figures 4 and 5 are a side view and a front view, respectively, of a cutting tool of the appliance of Figure 1.
- an electric household appliance able to shred plastic, cardboard and tin containers, is generally indicated 10.
- the appliance 10 comprises an outer casing 11 (Figure 1) which encloses in its upper and central portion a feeding section and in its bottom portion a cutting section.
- the feeding section comprises an internal chamber 12 able to receive a container 13 to be shredded, shown in the drawings as a plastic bottle.
- the container 13 is introduced into the chamber 12, preferably in an overturned position, through an upper opening 14 ( Figure 1) which may be closed by means of a lid (not shown) .
- the feeding section also comprises a crushing device having the function of crushing the container 13 to be shredded and cause it to advance towards the cutting section.
- the crushing device includes essentially a pair of rotating rollers 15 and 16 which are arranged parallel to each other in a front and rear position, respectively, the rear roller 16 being at a level slightly higher than that of the front roller 15.
- the two rollers 15, 16 are preferably made of superficially hardened metallic material so as to have a longer service life and are provided on their outer cylindrical surface with sharp projections or hooks 17 able to grip and draw the container 13 towards the following cutting station.
- the front roller 15 is made to rotate by an electric motor 18, via a gear 19, so as to draw the container 13 by means of its hooks 17 towards the cutting section cooperating with the hooked surface of the rear roller 16.
- a shaft 20 of the front roller 15 is mounted on a pivoting support 21 hinged with the structure of the appliance so as to pivot about a transverse axis (parallel to the axes of rotation of the two rollers 15 and 16) in such a way that the front roller 15 is displaceable between a position at a minimum distance from the rear roller 16 (shown in Figure 3) and a position at a maximum distance from the rear roller 16 (not shown) .
- the front roller 15 is pushed into the minimum distance position by pre-tensioned springs 22 arranged between the structure of the appliance and the pivoting support 21.
- the two opposite ends of the shaft 20 of the front roller 15 are inserted slidably in respective curved slots 23 (only one of which can be seen in Figures 2 and 3) . Thanks to the configuration described above, during operation the front roller 15 not only draws the container 13 towards the cutting station, but also crushes it against the surface of the other roller 16, thus reducing the dimensions of the container and therefore favouring the cutting action of the following station.
- the cutting station comprises basically a rotating cutting tool 24 in the form of a milling cutter provided with helical teeth 25.
- the number and .profile of the teeth 25 are chosen so as to permit to reduce plastic, cardboard and tin containers into fragments.
- the milling cutter 24 is provided with four teeth 25 inclined at 45° relative to the axis of rotation of the milling cutter ( Figures 4 and 5) .
- the milling cutter . is provided with six teeth inclined at 30°. Other configurations are obviously possible, however, as regards the number and inclination of the teeth.
- the teeth 25 of the milling cutter 24 are divided, along the axis of the milling cutter, into alternate segments 25d and 25s having a right-hand and a left-hand inclination, respectively, in order to prevent the cutting fragments from being drawn towards an axial end of the milling cutter.
- the milling cutter 24 co-operates, in order. to shred the containers, with a fixed cutter 26 ( Figure 3) , the cutting edge of which has a minimum play with respect to the cutting edges of the teeth 25.
- the milling cutter 24 is made to rotate by the same electric motor 18 which operates the roller 15, as it is mounted directly on the shaft of this motor. Thanks to the presence of the reduction gear 19, the speed of rotation of the milling cutter 24 is greater than that of the roller 15.
- the electric motor 18 which operates the roller 15 and the milling cutter 24 is activated, once the container 13 to be shredded has been inserted through the opening 14 of the feeding station, by pressing a special start-up button 27 ( Figure 1) .
- the scraps produced by shredding of the plastic, cardboard and tin waste are discharged downwards and may be collected inside a special cabinet 28 provided with storage drawers 29 and 30, each intended to store a type of material .
- the cutting system operates only if the lid of the feeding station is closed and, where the cabinet 28 is provided, if the storage drawers ' 29, 30 are correctly inserted inside the cabinet.
- Special sensors (known per se and not shown) detect the closed condition of the lid and the correct positioning of the drawers 29, 30 and send corresponding consent signals to an electronic control unit (also not shown) which manages the operation of the appliance 10, in particular the activation of the electric motor 18.
