A FOOD PROCESSING ARRANGEMENT

Abstract: A food processing arrangement includes a motor hous­ ing (2) pivotally mounted on a base (1) and a gearbox housing (3), upon which a bowl (4) for containing food to be processed is located, is integrally connected to the motor housing (2). A gearbox (7) provides two oppositely-extending co-axial ro­ tational drive axes (9, 10) for rotational drive of food pro­ cessing attachments. The first drive axis (9) provides a usable vertical axis, when the integral housings (2, 3) are in an un­ pivotted position relative to the base (1), and the second drive axis (10) provides a usable horizontal axis, when the housings (2, 3) are in a pivotted position relative to the base (1).

Description: A FOOD PROCESSING ARRANGEMENT This invention relates to a food processing arrangement. Conventional food processors and mixers are usually provided with a vertical drive shaft into which various mixing and/or processing attachments are inserted to provide the required preparation of foodstuffs placed within a container, such as a bowl, provided on the processor or mixer. The shaft is generally either driven from the top thereof and arranged to provide rotation of a whisk, dough hook, etc, as in the case of a mixer, or from the base thereof to provide rotation of a cutter blade, etc, as in the case of a processor. In addition to a vertical drive shaft, some food mixers are provided with a horizontal shaft connected to a gearing mechanism and a motor for rotationally driving the vertical shaft. Horizontally-disposed attachments, such as a food mincer, can opener, cream maker, pasta maker, coffee grinder, etc, may then be rotationally driven by the horizontal shaft. Additionally the horizontal shaft may, by suitable gearing, be provided with a slower rotational speed than the vertical shaft. It is an object of the present invention to provide a food processing arrangement, having a vertical drive shaft driven from the base thereof, which is also capable of receiving horizont ally- disposed attachments for the preparation of foodstuffs. According to the present invention there is provided a food processing arrangement comprising a base portion and a gearing arrangement arranged to be driven by a motor, characterised in that said gearing arrangement provides first and second oppositely-extending drive axes for rotational drive of attachments for food processing, at least said gearing arrangement being capable of pivotal movement relative to said base portion, so that said first axis is usable, when said arrangement is in an unpivotted position, and said second axis is usable when said arrangement is in a pivotted position. Preferably the first axis is generally vertical and the second axis is generally horizontal, when usable, and the gearing arrangement may be constructed so that the oppositely-extending drive axes are co-axial. The gearing arrangement is preferably rigidly connected to the motor housing and the housing is pivotally connected to the base portion, so that the housing and the gearing arrangement are together capable of pivotal movement relative to said base portion. The food pro processing arrangement is preferably provided with a control panel which is connected to the base portion so as to remain in a fixed position upon pivotal movement of the gearing arrangement. The gearing arrangement is preferably constructed so that the generally horizontal rotational axis provides a lower rotational speed than the generally vertical axis. The housing is also preferably provided with a second generally vertical rotational axis, which provides a higher rotational speed than the first-mentioned vertical rotational axis. The invention will now be further described by way of example only with reference to the accompanying drawings wherein: Figure 1 shows a schematic side view of one embodiment of a food processing arrangement, in accordance with the present invention, Figure 2 shows a sectional view of the embodiment shown in Figure 1, Figure 3 shows a schematic side view of the embodiment in a pivotted position, and Figure Ii shows a sectional view of the embodiment as shown in Figure 3. Figure 1 shows a food processing arrangement having a base 1, a motor housing 2 pivotally connected to the base 1 and integrally connected to a gearbox housing 3, upon which a bowl 4 for containing foodstuffs to be processed is located. A control panel 5, accommodating suitable user-operable control knobs, etc, for operating the processing arrangement, is attached to the base 1. In Figure 2, it can be seen that a motor 6 accommodated within the housing 2 drives a cycloidal action gearbox 7 via a belt 8, the gearbox 7 being accommodated within the housing 3. The gearbox 7 is arranged so as to provide two oppositely-extending co-axial rotational drive axes 9 and 10, the drive speed associated with axis 10 preferably having a lower rotational speed than that associated with axis 9. The bowl 4 is provided with a drive shaft 11, which is integrally formed with base 12 of the bowl 4 and is located over hub 13, which is concentric with the axis 9. Any suitable attachment, such as a whisk, dough hook, cutter blade, etc, for preparing foodstuffs within the bowl 4 may then be inserted down into the shaft 11 and driven for rotation by the motor 6, via the gearbox 7. The bowl 4 is preferably provided with a lid (not shown), which may also be provided with a safety interlock mechanism, so as to prevent rotation of the attachments before the lid is correctly positioned on the bowl 4. The arrangement may also be provided with a second vertical rotational drive axis 11;, which can be employed for operation of a food blender or liquidiser attachment requiring higher rotational speeds than the food processor attachments driven about axis 9. Drive axis 101 extending from gearbox 7 in an opposite direction to drive axis 9 baa a concentric hub 15, which is accommodated within a hollow 16 in the base 1 of the arrangement. With the food processing arrangement in this position, the axis 10 cannot be employed for rotational drive of attachments. However, Figures 3 and 4 illustrate the arrangement with the housings 2 and 3 in a pivotted position relative to the base 1, the bowl 9 shown in Figures 1 and 2 having been removed. It can be seen that the arrangement is particularly advantageous in that, upon pivotal movement of the housings 2 and 3, not only does the base l remain in a fixed position, but also the control panel 5 remains fixed, thereby facilitating control of the operation of the arrangement, irrespective of the position of housings 2 and 3. In the pivotted position, axis 10 is readily accessible, so that horizontally-disposed attachments such as a food mincer, can opener, cream maker, pasta maker, coffee grinder, etc, which are generally required to be rotated at a lower rotational speed than food processor attachments, may be inserted into hub 15 for rotational drive by the motor 6, the gearbox 7 providing the appropriate speed reduction. A suitable container (not shown) for collecting foodstuffs processed by a horizontally-disposed attachment driven about axis 10 may be positioned upon the base 1 alongside the pivotted housing 2, and may furthermore be correctly located by insertion of the container base into the hollow 16. Additionally, the base 1 of the arrangement may be provided with storage space for the various attachments and the control panel 5 may include electrical components for providing such facilities as a timer for controlling the food preparation time, a digital temperature sensor and/or weighing scales, the required storage space for these facilities also being provided on the base 1. A suitable latching mechanism may be provided to latch the housings 2 and 3 into either the first unpivotted position or the pivotted position. Furthermore, an interlock switching arrangement may be provided for disabling the arrangement unless the housings 2 and 3 are latched into either the unpivotted or pivotted position. It can thus be envisaged that the present invention provides a compact, but versatile, food processing arrangement, capable of receiving and driving different types of attachments for preparing foodstuffs in a variety of ways, whilst remaining easily controllable by a user, irrespective of the attachment being utilised.
