  • the bowl In a conventional configuration (not depicted), the bowl
  • the container 110 is formed of a base 23 and a side wall 20, and is arranged to engage with and stack on top of the bowl 10 in use so as to form a further food processing chamber (separate to the food processing chamber formed by the bowl 10). As will be described later on, the container 110 is capable of receiving drive from the kitchen appliance via an aperture (not shown) in the base.
  • the lid 1 is received on to an upper part of the container 110 for use, where the bayonet features 16 of the lid engage with corresponding bayonet features 21 on the side wall 20 of the container 110 (where these fixings are similar or identical to those used on the bowl 10).
  • the container 110 engages with the bowl 10 from above via a bayonet feature 15 on the side wall engaging with a corresponding feature on a flange 22 of the bowl 10.
  • the bayonet feature 15 on the container is similar or identical to the bayonet feature 16 on the lid 10.
  • the side wall 20 may be shaped and/or its thickness may be configured so as to accommodate the flange 17 of the lid 1 at one end and flange 22 of the bowl 10 (which is generally somewhat wider than the rest of the walls of the bowl 10) at the other end.
  • the lower part of the container 110 comprises a flange 24 for engaging with the flange 22 of the bowl.
  • the container 110 generally has the same exterior and interior diameter as the bowl 10 otherwise. The provision of a removable container 110 which fits on top of the bowl may improve the versatility of the kitchen appliance 100, in that it may allow use of an alternative processing chamber when it is not convenient or desired to use the bowl 10.
  • a first interlock mechanism is configured, which ensures that the switch of the kitchen appliance is not actuated (and thus a processing tool in the container 110 cannot be driven to rotate) unless the lid 1 is engaged with the container 110, the container 110 is engaged with the bowl 10, and the bowl 10 is engaged with the base 11 of the kitchen appliance. This may ensure safe operation of the container 110.
  • the lid 1 can be used with either the bowl 10 or container 110, and in either case the attachment of the lid 1 causes an interlock mechanism to allow actuation of the motor (where the same interlock rod 14 of the bowl 10 is used in either case). This may provide a convenient solution which saves space and avoids redundant componentry.
  • the drive shaft 9 only extends up until (proximate) the top of the bowl 10, so to allow the container 110 to receive drive from the motor an extension 4 for the drive shaft (or a drive shaft extension) 4 is provided.
  • the extension 4 is removably engaged with an end of the drive shaft 9 (the end closes to the top of the bowl 10) to receive rotational drive from it.
  • the extension 4 extends through the aperture in the container 110 to rotate within the container.
  • it engages with a bush or bearing in the lid, much as the drive shaft 9 engages with the same bush or bearing when the lid 1 is mounted directly on the bowl 10.
  • the drive shaft extension 4 comprises mounting features for receiving/mounting one or more rotatable tools which can be attached to the drive shaft extension 4 to receive rotary drive.
  • Suitable food processing tools for use with the container include the combination of a cutting disc 2 (i.e. a shredder/slicer disc) and a spreader disc 3, which are driven on the same shaft (i.e. the extension 40). Where this arrangement is used, shredded/sliced food falling from the shredder/slicer disc 2 lands on the spreader plate 3 and then moves towards the edge of the plate 3. Since the outlet 5 is the only outlet for the processed food, and since the plate 3 continues to move processed food about its periphery until it reaches the outlet 5, food processed within the container 110 is urged through the outlet 5.
  • the bowl or other container into which processed food is to be directed is relatively small or low-sided
  • a member 6 which acts as a (generally tubular) removable extension for the outlet (or, in other words, a removably-attachable outlet extension) is therefore provided which can be attached to the chute 5 to extend it further downwardly and/or outwardly so as to dispense more easily dispense food into the article.
  • the member 6 includes features 6a which engage with corresponding features (not shown) on the chute such that the member 6 can be slotted into place on the chute 5.
  • the lid 1 may be replaced by an alternative lid 13 comprising a processing tool.
  • Figures 4 to 6 show this alternative configuration, which may be used to allow juicing to be performed in the container.
  • the alternative lid 13 includes a rotatable tool (preferably a reamer) 12.
  • the rotatable tool 12 is located to receive rotary drive from the drive shaft extension 4, and is shaped such that the open end of a halved citrus fruit (e.g., an orange or lemon) can be pressed down onto it and have the soft pulp inside it sufficiently mashed by the rotatable tool 12 to release its juice.
  • a halved citrus fruit e.g., an orange or lemon
  • the rotatable tool 12 is thus accessible from the outside of the container when the alternative lid 13 is attached to the container 110.
  • the lid 13 is generally bowl-shaped (with the rotatable tool 12 being provided in its centre), such that the lid 13 extends into and takes up most of the room within the container 110. This prevents the tool 12 from extending too far above the lid 13, and allows juice to pool in the lid 13.
  • the alternative lid 13 when locked in place to the container 110 actuates the biased member 7 to actuate a switch in the kitchen appliance 100 (and thus permit energising of the motor) without the need to protect the rotatable tool 12 with an additional cover.
  • the feature(s) on the lid 13 are identical to that of the previously described lid 1, such that the biased member 13 is actuated in the same way.
  • the alternative lid 13 comprises a bayonet formation 25 and a formation 26 for engaging the biased member 7, where these are very similar or identical to the corresponding features on the previously described lid 1.
  • the reamer 12 is preferably made of a relatively soft material compared to the hard materials from which slicing/cutting tools are made (e.g., stainless steel), such as plastic. Since the rotational speed needed for juicing via the reamer 12 is different to that needed for food processing via the shredding/slicing disc 2, the reamer 12 is driven to rotate by the drive shaft extension 4 via gearing 12a (which is internal to the reamer).
  • the gearing 12a serves to change the speed of rotation of the rotatable tool 12 relative to the speed of rotation of the drive shaft extension 4, and preferably serves to make the speed of rotation slower for added safety.
  • the alternative lid 13 and/or the rotatable tool 12 further comprises means for protecting against overload.
  • the gearing 12a may be formed of plastic so as to break (i.e. , it is a “sacrificial gear”) if the rotatable tool 12 becomes jammed, preventing harm to the motor of the base 11.
  • the gearing 12a may include a slip-clutch configured to slip if the rotatable tool 12 becomes jammed.
  • the alternative lid 13 is in fluid communication with the container.
  • the lid comprises a filter 13a for filtering juice, which is formed such that it is in fluid communication with the container 110 chamber beneath, that in turn is in fluid communication with the outlet 5.
  • juice released from fruit by the rotatable tool 12 flows through narrow apertures in the filter (which prevents large pieces of pulp following the juice), down the outlet 5, also down through the outlet extension member 6 if it is attached, and into a storing article (receptacle) provided by the user (e.g., a jug).
  • the filter 13a of the juicing tool 13 is preferably located at the lowest point within it to encourage juice in the juicing tool 13 to flow towards it.
  • the base 23 is angled slightly towards the outlet 5 to encourage the flow of juice through the outlet 5.
  • the container 110 is provided with a juicing mode and a slicing mode, where both of these modes use the same outlet 5 and so output juice or cut foodstuffs away from the bowl 10.
  • the container 110 may also be removed and the bowl 10 used with the lid 1 as normal (where processing tools are fitted to the drive shaft 9).
  • the described arrangement may improve the versatility of the kitchen appliance 100.
  • the outlet extension 6 is preferably shaped to be stored in or around the feed tube 18 of the lid 1.
  • One or both of the outlet extension 6 and feed tube 18 may be provided with suitable latches or other releasable attachment means (e.g. tabs received in corresponding slots) to allow the outlet extension 5 and the feed tube 18 to be attached to each other.
  • the releasable attachment means may be the same means as those by which the outlet extension 6 is attached to the outlet 5.
  • the lid 1, bowl 10, and container 110 are preferably made of a transparent plastic (e.g., polycarbonate or copolymer) to permit the user to see what is going on inside them. All components that come into contact with food are preferably food-safe, and for example should be BPA-free. All components other than the base 11 are preferably dish-washer safe - for example, they should preferably not include any oil lubricants that may be lost/dried out during washing in a dish-washing machine.
  • a transparent plastic e.g., polycarbonate or copolymer
  • any other way of transmitting actuation via the container 110 and bowl 10 may also be used. This includes wired connections for a circuit that is completed by the lids 1 , 13, RFID transmission between the base 11 and an RFID tag in the lids 1, 13 via a two-part waveguide, replacing the switch in the base 11 with a reed-switch actuated by a magnet in the interlock rod (or push-rod) 14 when it is moved, and other conceivable methods of interlock actuation.
  • At least one of the tool mounting features on the drive shaft extension 4 may correspond to those on the drive shaft 9. This may allow, for example, the cutting disc 2 to be used either in the container 110 (mounted on the extension 4) or in the bowl 10 (mounted on the extension 9).
  • a further container 110 may be provided which includes no base (i.e. it includes only side walls), such that the further container serves to extend the height of the bowl 10. This may be useful where it is desired to increase the space within the bowl 10 for certain applications.
