- Other embodiments stir so slowly that the direction of rotation need not be reversed, the blades need not be reversed, the blades being ineffective for cutting foods at stirring speeds.
- FIG. 3A through FIG. 9C show embodiments of a reverse drive module for use in a cooking apparatus.
- a one-way bearing can enable multiple couplings to be used where a motor, drive train, or driven gearbox, allows an axle, driven shaft or spindle to be rotated in both directions. In one (first) direction a one-way bearing spins freely, while in the other (second) direction the one-way bearing locks and thus transmits torque.
- FIG. 3A and FIG. 3B show a one-way clutch bearing in use for creating a primary drive assembly configuration and a secondary drive configuration.
- the primary drive configuration works when the bearing is engaged or locked, wherein both the primary drive coupling and secondary drive coupling move in the same direction.
- the secondary drive configuration is engaged when the spindle is reversed, such that the bearing is free-spinning in its disengaged configuration.
- a 'brake' element or module can be used to prevent free-spinning of the primary drive coupling, and corresponding mixing or cutting arms attached thereto.
- the primary drive By applying an external resistive force against a flywheel, which is statically coupled to a primary drive coupling, the primary drive can be restrained (including any coupled mixing blades) while the secondary drive module (and associated secondary drive coupling) can be allowed to operate.
- FIG. 3A shown an embodiment device 1000 which includes a food (mixing, processing or cooking) vessel or reservoir 1010 operatively associated with blending/mixing arm (or blade) elements 1012.
- the arm elements or blade assembly being rotatably coupled to the vessel through a dual driven coupling module 1014.
- the dual driven coupling 1014 comprises an outer shaft or sleeve assembly 1016 that is directly coupled to the blender/mixer arms element 1012 (for example using screws 1017).
- the outer shaft/sleeve assembly can be rotatably coupled to the food vessel 1010 by one or more bearings 1018.
- An attachment drive coupling 1020 is driven by: an inner shaft 1022, located within the outer sleeve assembly 1016); and secondary driven coupling 1024.
- the inner shaft is rotatably coupled to the outer sleeve by bearings 1026.
- the primary driven coupling 1032 is in the form of a female coupling configured within the outer sleeve
- V seals can be used to restrict ingress to the driven coupling and bearings.
- a drive module 1040 can be operatively associated with the driven couplings 1014.
- the drive module 1040 can include a primary drive coupling 1042 and a secondary drive coupling 1044.
- a primary drive coupling 1042 engages the primary driven coupling 1032.
- one-way bearings 1046 enable both independent and dependent rotation of the primary and secondary drive couplings, with respect to a motor based housing 1048.

- a brake assembly 1054 can be used to restrict rotation of the flywheel 1052.
- a solenoid 1056 can operate to move a brake pad element 1058 into abutting engagement with the flywheel 1052.
- the cooking appliance can heat, blend, process ingredients within the food vessel using high speed blades. However, this can and usually will result in the food being broken down into a relatively fine consistency. It would be beneficial to enable an attachment (for example a food processor disc for grating or slicing ingredients) having a relatively high rotational speed to process the ingredients entering into the vessel, while the blending/stirring arms remain stationary (or rotate at a relative low rotation speed).
- high speed refers to motor or blade speeds that result in the break down or processing foods in the context of routine cooking.
- Low speed refers to blade or motor speeds that achieve stirring without significant food break down or change in the food.
- a drive shaft (spindle or axle) 1060 is directly coupled to the secondary drive coupling, and indirectly coupled to the primary drive coupling through the one-way bearings 1046. It would be appreciated that the drive shaft 1060 can be driven by a motor or gear assembly or belt assembly. It would be further appreciated that the drive shaft can be driven by a dual-motor drive module.
- FIG. 3B shows the drive couplings 1040 engaged with driven couplings 1014.
- An attachment element (processing module) 1070 is coupled to the attachment drive coupling 1020. It would be appreciated that the attachment element 1070 can be operated in conjunction or independently with the blade/ arms element 1012, depending on the driven direction of the drive shaft 1060.

- an embodiment brake assembly 1100 can incorporate a ratchet mechanism between a brake element 1102 and the flywheel 1052.
- the brake element can be biased into ratcheting engagement with the flywheel using a spring 1104. It will be appreciated that, when the driveshaft 1060 is rotated such the secondary drive coupling rotates freely within the primary drive coupling, the brake assembly acts to restrict rotation of the primary drive coupling through resisting rotation of the flywheel.
- an embodiment brake assembly 1110 includes a friction plate 1112 that travels vertically to engage the base of the flywheel, without allowing rotation of the friction plate.
- the friction plate is driven vertically upward by the rotation of the driveshaft 1060 in a direction wherein the secondary drive coupling rotates freely within the primary drive coupling.
- This rotation of the driveshaft 1060 causes a radially extending pin 1114 (fixed to the driveshaft) to slide within an inclined slot 1116 formed in a slave block 1118 (slidably located about the drive shaft) - such that the pin moves down the incline slot 1116 - causing the slave block 1118 to rise, and thereby move the friction plate upwardly into abutting contact with the flywheel 1052.
- the slave block 1118 continues to rotate beneath the friction plate.
- the pin 1116 slides up the inclined slot, thereby allowing the slave block 1118 to lower and disengage the friction plate. It will be appreciated in this orientation that while rotating the driveshaft in this configuration, the one-way bearings are engaged to cause simultaneous rotation of both the primary drive coupling and secondary drive coupling.
- an embodiment brake assembly 1120 can include a mechanical brake or clamp.
- the flywheel 1121 includes a plurality of circumferential detents 1122 for receiving a brake pin 1124.

- the brake pin can be biased into one of the configurations by a spring 1136.
- an embodiment brake assembly 1140 can include the flywheel having a radially increasing depression 1142 - that is adapted to engage a locking pin 1144 for resisting rotation of the flywheel in a first direction 1146. It will be appreciated that rotation of the driveshaft and flywheel in the opposite direction will cause the locking pin to ride out of the depression 1142.
- a control element 1148 can be used to bias the locking pin 1144 into or out of locking engagement with the flywheel.
- a blade lock assembly can be configured within the jug or driven couplings. In this embodiment there is then no need to incorporate a brake assembly acting on the flywheel component.

- a further bearing 1154 can be included to allow free rotation of the attachment coupling.
- an embodiment locking assembly 1160 can be incorporated with the attachment device 1162.
- Identification of the attachment element can be made through a wireless communication.
- the attachment element 1210 can include a near field communication (NFC) or radio frequency identification (RFID) element 1212, which can cooperate with a reader/sensor 1214 located within the cooking apparatus.
- the reader/sender can be coupled to a processor module 1216 for enabling identification of the attachment element.
- the vessel could also include a hall-effect sensor or interlock switch for confirming coupling of the attachment element to the attachment coupling. This would be beneficial in limiting operation of the motor or limiting motor speed when the attachment element is located proximal to the sensor element 1214.
- FIG. 7B and FIG. 7C show use of a further wireless communication element (for example: NFC, RFID or hall effect) 1222 in the attachment element 1210, such that a second reader/sensor device 1224 can appropriately detect and identify the element 1222 - conveying the identification data to a processor module 1216.
- the processor may use the identification data to alter operational parameters of the appliance. Operational parameters include blade or accessory speed, or maximum speed, cooking times or temperatures or other modifiable functions of the appliance.
- FIG. 7B shows the identification element or sensor or detector 1222 and corresponding sensor/reader 1224 being located about a periphery of the vessel.
- FIG. 7C shows the identification element 1222 and corresponding
- detection/ reader element 1224 being located more centrally about a vessel lid.
- the accessory can include a chopping blade 1230 located below a food chute 1232.
- the food chute 1232 having a cooperating pusher 1234 that slidably engages within the chute.
- a cooking vessel can preferably present a relatively large cooking volume, and more preferably present a relatively large base cooking surface.
- the mixing arms/blades are required to be correspondingly large to reach the extremities of the cooking surface for enabling appropriate stirring during cooking.
- This increased diameter/radius can place additional load on the driving motor at high speed (for example during blending).
- the device can include differential gearing for driving the primary drive coupling at a different (typically lower) speed than the secondary drive coupling.
- a primary drive coupling 1302 can be driven by a sleeve drive element 1303, and the secondary drive coupling 1304 driven by a shaft drive element 1305, rotatably sleeved within the sleeve drive element.
- an embodiment drive gear assembly 1310 includes a motor 1312 to drive a first bevel gear 1314, which in turn drives a primary bevel gear 1315 coupled to the primary drive.
- the bevel gear 1314 further drives a gear assembly 1316 for coupling power to a secondary drive.
- the gear assembly 1316 can include an intermittent idle gear 1317 for coupling to the secondary drive gear 1318. It would be appreciated that by selection of appropriate gear ratios, a predetermined drive ratio between the primary and secondary drives can be achieved.
- FIG. 8B shows a gear coupling 1320, where a motor 1322 drives a bevel gear 1324 for simultaneously driving a primary gear 1325 and secondary gear 1326. It will be appreciated that this gear coupling will achieve opposite (equal velocity) rotation of the primary and secondary drives.
- FIG. 9A through FIG. 9C shows an alternative gear assembly 1400 that uses a primary pinion gear 1402 to drive a primary gear 1404.
- the primary gear is defined by a female cavity having gear teeth orientated about the internal circumference.
- a second pinion gear 1406 is driven by the motor, and selectively engages a secondary gear 1408. It would be appreciated that the gearing ratios can be selected to provide a differential rotational speed between the primary drive 1420 and secondary drive 1422. It will also be appreciated that in this configuration, the primary drive and secondary drive rotates in opposite directions.
- the second pinion gear 1406 can be selectively brought into and out-of engagement with the secondary drive gear 1408, depending on the rotational direction of the motor.
- clockwise rotation of the motor causes a radial pin 1410 to slide downward along an inclined slot 1412 formed in the second pinion gear, thereby raising the second pinion gear into geared engagement with the secondary drive gear 1408 (as shown in FIG. 9A).
- Reversing the rotation of the motor causes the radial pin to slide upwardly along inclined slot 1412 to draw the secondary pinion gear downward and out of engagement with the secondary drive gear 1408 (as shown in FIG. 9B).
- a one-way clutch element 1430 can be incorporated into the secondary pinion gear, for selective activation or deactivation of the second drive, based on the rotational direction of the motor. It will be appreciated that rotation of the motor in one direction will cause the clutch element to engage and rotate the pinion gear 1432 - to thereby drive the secondary drive gear 1408. Rotation of the motor in the opposite direction can cause the clutch 1430 to disengage, thereby allowing the pinion gear 1432 to spin freely - thereby not driving the secondary drive gear 1408.
- a cooking apparatus can include a dual motor drive, whereby one of a plurality of drive motors can be selected to engage or drive a drive shaft, gearbox or drive coupling.
- a cooking appliance can service multiple functions, including blending, processing and cooking.
- Food blending or processing is usually performed with blades or arms rotating at about 300rpm to isooorpm.
- the food is typically stirred to avoid sticking to the base of a heated vessel, wherein the blades or arms are rotated at less than 2orpm to minimise the breaking down of the food during the stirring action.
- motor rotational speed can be varied by applying different voltages or varying frequencies
- motors typically operate at maximum torque only within a narrow range of rotational speed.
- An electronic controller can be used to reduce the effect of a lack of torque, whereby sensing a blade/ arm being stalled or becoming stalled, the control voltage can be increased momentarily.
- the increased voltage being applied to the motor may also momentarily increase the rotational speed of the arms/blades.
- a gearbox can be used to provide a plurality of gearing ratios between the motor and arms/blades, such that a preferred rotational speed of the arms can be selected while maintaining a substantially optimal rotational speed of the motor.
- gearboxes often introduce noise and can occupy substantial room in an appliance.
- switch reluctance and brushless DC motors motors can maintain a usable level of torque across a wide range of rotational speeds, they typically operate at rotational speeds above 4orpm. It will also be appreciated that switch reluctance brushless DC motors are typically more expensive than common universal motors.

- the secondary motor is configured to provide a counter rotation of the blade/arms during the secondary stirring mode, when compared to the primary processing mode. It will be appreciated that this counter rotation of the main blades/arms enables, the leading edge (typically sharper edge) of the blade/arm used during the processing mode becomes a training edge during a stirring mode - such that the arm may 'push' or 'stir' the food in the vessel.
- the secondary asynchronous motor engages the shaft 2022 through a pair of bevelled gears 2040 and 2042 - for rotating the shaft 2022.
- FIG. 11A and FIG. 11B show an alternative embodiment kitchen apparatus 2100, wherein a bevelled gear 2140 is operatively associated with a one-way (or clutch) bearing 2144 for enabling free spinning of the gear coupling to decouple the secondary motor 2032 (asynchronous or synchronous) from the drive
- the one way (clutch) bearing 2144 is used to couple the bevelled gear 2140 to the secondary asynchronous motor.
- the primary universal motor can be engaged during the processing mode for high speed turning of the blade/arms.
- the secondary asynchronous motor can be engaged in the stirring mode to cause low speed rotation of the mixing arms (in a reverse direction relative to the operation of the primary universal motor - as shown in FIG. 11B).
- Rotation of the asynchronous motor 2032 causes the one-way (clutch) bearing 2144 to engage the bevel gear 2140 that drives the slave gear 2142 causing rotation of the shaft 2022 and stirring arms 2014.
- each of the primary motor and/or secondary motor can be selected as any one from the set of: asynchronous motor, synchronous motor, brushless motor, indication motor, switched reluctance motor, and reluctance motor.
- asynchronous motor drives the gear 2140 and 2142 to rotate the shaft 2022.
- the asynchronous motor 2032 can drive rotation of the shaft 2022 and the primary universal motor 2030.
