    The scraper device (1) comprises a base (3) with a drive motor (5) installed therein. The connection between the drive motor (5) and the Raffelscheibe (39) is effected by a Übertriebsanordnung which comprises two axially mutually displaceable crown gears (15, 17). The crown gears (15, 17) engage only when the lid (23) is correctly placed on the edge (51) of the Raffelscheibenraums (25) and secured by a bolt (53).

    Description: The invention relates to a shaker with a drum housing according to the preamble of patent claim 1.
    [0002] Raffle devices, as the name implies, are used for raffling food in the kitchen. The devices can have a manual drive with a crank or an electric motor. For devices with electric drive is of great importance that before closing the lid on the disc-shaped grater, this can not be set in rotation. In other words, the drive motor must be disconnected from the grater even if the operation switch is set to "on".
    Raffle devices are known from the prior art, which prevent the commissioning of the electric motor when not properly closed Raffelscheibengehäuse via an electrical contact. Electrical contacts, however, are susceptible to soiling and corrosion, which are caused in the case of slicers which allow fruits or vegetables to escape not only grating but also liquid. In general, electrical contacts that can be affected by the processed fruits or vegetables, as they are in the immediate vicinity of the Raffelguts be avoided.
    An object of the present invention is therefore to provide a Raffelgerät, in which to prevent the drive of the Raffel disc is not excluded when not properly closed Raffelgehäuse or incorrectly patched Raffel disc commissioning of the latter. (Sentence ) This object is achieved by a Raffelgerät according to the characterizing features of claim 1. Advantageous embodiments of the Raffelgeräts are described in the dependent claims.
    The mechanical interruption of the drive train from the engine to Raffelscheibe, which is inevitably present when the Raffelscheibe is not correctly inserted in Raffelscheibenraum or if the lid is not correctly placed, prevents a transfer of torque from the drive motor on the Raffelscheibe. The operating train is interrupted when the following on an idler after the drive wheel of the drive motor output gear is lifted by a spring, as long as from the top through the cover of the Raffelscheibegehäuses no pressure is exerted on the driven wheel.
    Reference to an illustrated embodiment, the invention will be explained in more detail below. Show it:
    1 is a vertical section through a Raffelgerät with electric drive,
    2 shows a cross section through the Übertriebsbereich from the drive motor to the output on the Raffelscheibe,
    Fig. 3 is its perspective view of the Übertriebszahnräder and
    Fig. 4 is an exploded perspective view of the drive elements of the Raffelgeräts.
    Reference numeral 1 denotes a shaker with electric drive. In a foot or base 3 made of plastic or die-cast aluminum, an electric drive motor 5 is used. At the vertically extending drive shaft 7, a drive gear 9 is fixed, which meshes with a driven gear 11. The driven gear 11 is rotatably mounted on an axis fixed to the housing 13. The front side is within and concentric with the teeth of the output gear 11, a first crown gear. 15 trained. This is rotatably connected to the output gear 11 or machined from one piece. Above the first crown gear 15, a second crown gear 17 is rotatably mounted on the axis 13 rotatably and axially displaceable. Between the first and the second crown gear 15, 17, a helical spring 21 is inserted in an axially extending central undercut 19. The coil spring 21 presses the second crown gear 17 with the lid 23 open of the arranged above the base 3 Raffelscheibenraums 25 out of engagement with the first crown gear 15. Subsequently to the second crown gear 17 is fixed thereto or as a unit a hollow connecting shaft 27 attached or formed. The connecting shaft 27 then comprises, following the second crown gear 17, a cylindrical section 29 adjoined by a second cylindrical section 31, on the periphery of which at least one rib 33, but preferably a plurality of ribs 33, is formed. The apices S of the ribs 33 are at a radial distance from the axis of symmetry of the connecting shaft 27, which is less than or equal to the radius of the first cylindrical portion 29.
    On the upper end of the axis 13 sits a locking element 35 with a circumferential groove 37th
    A Raffelscheibe 39 with a centrally disposed opening comprises at the bottom a sleeve 41. The inner diameter of the sleeve 41 is dimensioned such that the sleeve 41 with the Raffelscheibe 39 aufsteck- on the connecting shaft 27 and on the connecting shaft 27 is axially displaceable , In the bore of the sleeve 41 at least one or more grooves 43 are formed, in which engage the at least one rib on the connecting shaft 27 and can produce a rotationally fixed connection between the two elements.

    Claims (9)
    [1]
    The axis 13 with the attached at the upper end locking member 35 penetrates the lid 23 for the Raffelscheibenraum 25 and projects beyond the lid 23. On the locking element 27, a circumferential recess 37 is formed. When loose placing the lid 23 on the Raffelscheibenraum 25, the lower end face 45 of the sleeve 41 comes into axial contact with the end face 47 on the first cylindrical portion 29 of the connecting shaft 27. By the spring 21, the connecting shaft 27 in the non-operating position slightly after shifted above, such that the lid 23 does not rest with its lower edge 49 at the upper edge 51 of the Raffelscheibenraums. Only upon depression of the lid 23 on the edge 51 of the Raffelscheibenraums 25 and thus compress the spring 21, the two crown gears 15 and 17 engage. In order to obtain a permanent engagement of the crown gears 15, 17 and thus a torque transmission from the drive motor 5 to the Raffelscheibe 39, a latch 53 is pivotally mounted on the lid surface. In the latch 53 suitable projections are formed, which engage in the recess 37 on the locking element 35 and embrace. As an alternative to a pivotable latch 53, of course, a sliding latch can be provided. From the description it can be seen that the drive motor 39 can only put the raffle disk 39 in rotation, if previously brought by the placement of the lid 23 on the Raffelscheibengehäuse 25, the two crown gears 15, 17 against the force of the spring 21 in mutual engagement have been. The two crown gears 15, 17 preferably have a sawtooth toothing in order to exert no axial forces in the direction of the cover 23 during the torque transmission from the drive motor 5 to the grating disk 39. Once, intentionally or accidentally, the latch 53 is opened, the connection to the drive motor 5 is automatically interrupted, even if it is still supplied via an electrical switch with electrical power. claims
