The various details of the user interface 120 and various embodiments of the user interface 120 will be described more fully below.

Referring now to the embodiment illustrated in FIGS. 11-13, it is contemplated that the underside 130 of the lid 14 can include a stir-assist interlock 132 that is configured to engage a top portion 134 of the processing attachment 18 that is engaged with the stirring mechanism 16. The stir-assist interlock 132 can include a recess defined within the underside 130 of the lid 14 that is configured to vertically position the top portion 134 of the processing attachment 18 to prevent lifting of the processing attachment 18 and also prevent lateral wobble of the process attachment as it is manipulated within the interior volume 28 of the container 12. The stir-assist interlock 132 can be disposed within a lid arm 140, where the lid arm 140 is integrated within at least a portion of the lid 14. In this manner, the lid arm 140 includes and extends from the stir-assist interlock 132 and extends to the hinge 144. It is also contemplated that the lid arm 140 can be used to integrate the stir-assist interlock 132 into operable communication with other interlock devices of the cooking and processing appliance 10. These interlock devices can include, but are not limited to, the lid-activated interlock assembly 146, one or more dedicated interlocks 148, the container locking mechanism 310, combinations of these, and others.

Additionally, referring again to FIGS. 21, 22 and 26, in order to further secure the processing attachment 18 to the stirring mechanism 16, a blade shaft 136 of the stirring mechanism 16 can include a spiral-type profile 138, including, spiral surfaces, spiral grooves, spiral-type flanges 142, combinations thereof, or other spiral-type configurations. It is contemplated that the spiral-type profile 138 of the blade shaft 136 is cooperative with a corresponding attachment receptacle 22 defined within each processing attachment 18. According to the various embodiments, when the processing attachment 18 is placed upon the blade shaft 136 having the spiral-type profile 138, the processing attachment 18 is at least partially rotated as the processing attachment 18 is slidably engaged with the blade shaft 136. The spiral-type profile 138 of the blade shaft 136 minimizes play of the processing attachment 18 as it is manipulated upon the stirring mechanism 16 and through the interior volume 28 of the container 12. Additionally, the spiral-type profile 138 of the blade shaft 136 exerts a screw-type force upon the processing attachment 18 such that as the processing attachment 18 is rotated within the interior volume 28 by the stirring mechanism 16, a downward biasing force is exerted upon the processing attachment 18 within the interior volume 28 of the container 12. This downward biasing force is configured to substantially retain the processing attachment 18 in position upon the blade shaft 136 and within the interior volume 28 of the container 12. In addition to the spiral-type profile 138, the blade shaft 136 can include one or more alignment surfaces that can be implemented in conjunction with each of the processing attachments 18. The alignment surface of the blade shaft 136 can serve to position the processing attachment 18 in a predetermined rotational position with respect to the blade shaft 136. In such an embodiment, the alignment surface can include one or more rounded areas of the blade shaft 136 positioned adjacent to one or more flat areas of the blade shaft 136. As exemplified in FIG. 26, the alternating curved and flat surfaces of the blade shaft 136 can result in a “double opposing D” cross-sectional configuration. This “double opposing D” configuration can be used in conjunction with the spiral-type configuration 138 to secure the processing attachment 18 onto the blade shaft 136. Other alignment surfaces can include, but are not limited to, flanges, notches, channels, irregular shapes, curvilinear geometries, combinations thereof and others. It is further contemplated that an interior portion of each processing attachment 18 can be configured to include a mating spiral-type profile 138 that slidably engages the alignment surface or surfaces of the drive shaft 136.

It is contemplated that in various embodiments of the cooking and processing appliance 10 having bi-directional stirring capabilities, when the processing attachment 18 is rotated in the opposing direction, the spiral-type profile of the blade shaft 136 can, in some embodiments, exert a vertical biasing force 160 upon the processing attachment 18, where such a vertical biasing force 160 is placed upon the processing attachment 18, the stir-assist interlock 132 described above serves to maintain the position of the processing attachment 18 upon the blade shaft 136, as the blade shaft 136 is rotated to operate the processing attachment 18 within the interior volume 28 of the container 12. In addition to the spiral-type profile 138, the blade shaft 136 can include other retention features that cooperate with the various processing attachments 18 to substantially secure the processing attachments 18 on to the blade shaft 136 and also substantially prevent slippage of the processing attachment 18 during use of the cooking and processing appliance 10.

Referring now to the embodiments illustrated in FIGS. 9-11, 20 and 23-28, the cooking and processing appliance 10 includes the container 12 that is selectively removable from the housing 20. The cooking and processing appliance 10 can include a conductive heating element 150 as part of the heating structure 26 that is in communication with the interior volume 28 of the container 12 for heating the various food items placed therein. It is contemplated that the conductive heating element 150 can be disposed within the base 52 of the container 12. In this manner, when the container 12 is engaged with the receptacle 22 of the housing 20, the electrical system 152 disposed within the housing 20 delivers power through the receptacle 22 and into the base 52 of the container 12 for operating the conductive heating element 150 disposed within the base 52 of the container 12. In order to protect the mechanisms disposed within the housing 20 as the conductive heating element 150 reaches a predetermined temperature, the receptacle 22 can include a heat shield 154 disposed on a top surface 156 of the receptacle 22, such that as the conductive heating element 150 reaches a predetermined temperature, which can be in excess of 400° or more, the mechanical aspects of the cooking and processing appliance 10 contained within the housing 20 are substantially protected during operation of the heating functions of the cooking and processing appliance 10.

Referring now to the embodiment illustrated in FIGS. 9, 10, 20 and 23-25, the heating mechanism for the cooking and processing appliance 10 can include a thermostat 170 that engages the base 52 of the container 12 for monitoring the temperature of the container 12 and of the interior volume 28 of the container 12. The thermostat 170 can include a thermostat pin 172 that extends upward from the receptacle 22 to engage the base 52 of the container 12. The thermostat pin 172 is attached to thermostat wires 174 that extend to the control 40 of the cooking and processing appliance 10 for conveying information regarding the temperature of the container 12 and the interior volume 28 of the container 12 to the user through the user interface 120. In order to monitor and regulate the temperature of the conductive heating element 150 disposed within the container 12, the thermostat pin 172 is configured to extend at least partially through the conductive heating element 150 and into a pin recess 176 defined within the conductive heating element 150. In this manner, an end of the thermostat pin 172 can substantially engage the base 52 of the container 12 such that temperature measurements can be taken of the container and the interior volume 28 of the container 12. Accordingly, substantially accurate regulation of the temperature of the container 12 and the interior volume 28 of the container 12 can be maintained through the engagement of the thermostat pin 172 to the base 52 of the container 12 through the pin recess 176 defined within the conductive heating element 150. It is also contemplated, in various embodiments, that the engagement between the container 12 and the receptacle 22 can define a thermocouple that is configured to monitor the temperature of the interior volume 28 of the container 12.

Referring again to the embodiments illustrated in FIGS. 9-11, 20 and 23-25, the heating element disposed within the container 12 can be any one of various heating elements that can include, but are not limited to, a conductive heating element 150, an induction heating element, a combination thereof, or other similar heating element. In embodiments having an inductive heating element, the engagement of the receptacle 22 and the container 12 utilizes an electrical current disposed through a portion of the receptacle 22 to create an electromagnetic field within a portion of the receptacle 22. The electromagnetic field extends into a portion of the container 12 to create an induced electromagnetic field within a portion of the container 12. As a result, an induced electrical current is created that runs through the heating element disposed within the container 12. In this manner, the induced electrical current within the container 12 creates heat that can be transferred into the interior volume 28 of the container 12 for heating food items placed therein.

According to various embodiments, it is contemplated that the heating structure 26 can be at least partially located within the housing 20 such that heat energy from such a heating structure 26 can be transferred through the receptacle 22 and into the interior volume 28 of the container 12. In such an embodiment, the receptacle 22 can be configured to operate as an induction or conductive heating element 150 to provide heat to conventional cooking utensils, such as pots, pans, skillets, bakeware, and the like. It is also contemplated that such a conventional cooking utensil or various embodiments of the container 12, configured to be oven-ready, can be transferred from the receptacle 22 and placed within an oven for further cooking.

Referring again to the embodiment illustrated in FIGS. 11 and 23-25, the housing 20 can include a motor cavity 190 within which the motor 24 is disposed. It is contemplated that the motor 24 is engaged with a drive mechanism 192 that is in communication with the stirring mechanism 16 of the container 12. According to the various embodiments, the drive mechanism 192 of the housing 20 can include a drive transfer mechanism 194, such as a belt-drive that extends from a drive shaft 196 of the motor 24 to an impeller shaft 198 disposed within the housing 20 beneath the stirring mechanism 16. As the motor 24 is activated, the motor 24 operates to rotate the drive shaft 196 in the predetermined direction. The drive transfer mechanism 194 then transfers the rotation of the drive shaft 196 to turn the impeller shaft 198. A belt, chain, or other drive member can be used as the drive transfer mechanism 194 and places the drive shaft 196 in communication with the impeller shaft 198, such that the rotation of the drive shaft 196 also rotates the impeller shaft 198 to turn the stirring mechanism 16. It is also contemplated that instead of a belt or chain, the drive transfer mechanism 194 can be a gear train, drive-type shaft, or other mechanical-type drive mechanism 192 that can transfer force from the motor 24, through the drive transfer mechanism 194, and into the impeller shaft 198, to rotate the stirring mechanism 16 of the container 12. It is also contemplated that the drive mechanism 192 can include a gear reduction system that assists in providing greater torque to the stirring mechanism 16 when the motor 24 is operated at lower speeds.

Referring again to the embodiments illustrated in FIGS. 11 and 23-25, the base 52 of the container 12 includes a drive hub 210 that is disposed at a lower portion of the stirring mechanism 16 of the container 12. The drive hub 210 extends downward from the base 52 of the container 12 and engages a hub receiver 212 defined within the receptacle 22 of the housing 20. The hub receiver 212 is in communication with the impeller shaft 198, such that as the impeller shaft 198 rotates, the hub receiver 212 also rotates, thereby also rotating the drive hub 210 and the remainder of the stirring mechanism 16. The engagement between the drive hub 210 and the hub receiver 212 can include various mating mechanisms that can include, but are not limited to, various mating protrusions, a gearing interface, magnetics or electromagnetic securing mechanisms, cooperative physical mating features defined within each of the drive hub 210 and hub receiver 212, as well as other similar interface mechanisms. The mating or substantially fixed engagement between the drive hub 210 and the hub receiver 212 is configured to substantially prevent slippage of the stirring mechanism 16 during operation of the stirring or other food processing functions of the cooking and processing appliance 10.

Referring now to the embodiment illustrated in FIGS. 9-11 and 23-25, when the container 12 is placed upon the receptacle 22, the drive hub 210 of the stirring mechanism 16 within the container 12 can be inserted into the hub receiver 212 contained within the receptacle 22 of the housing 20. As discussed above, various physical mating features or alternate mechanical engagement features can be utilized to substantially secure the drive hub 210 within the hub receiver 212. When the user of the cooking and processing appliance 10 activates the motor 24, the drive shaft 196 of the motor 24 rotates the drive transfer mechanism 194 to transfer the rotational force from the drive shaft 196 to the impeller shaft 198. The rotation of the impeller shaft 198, in turn, rotates the hub receiver 212. In this manner, through the engagement of the hub receiver 212 and the drive hub 210, the hub receiver 212 rotates the drive hub 210 to also rotate the stirring mechanism 16 and the blade shaft 136 having the spiral-type profile 138.

Referring again to FIGS. 9-11 and 23-25, the motor 24 disposed within the housing 20 can be a two-directional motor that can rotate the drive shaft 196 in clockwise and counterclockwise directions. Alternatively, various gearing mechanisms can be included within the motor 24 that can be modified to redirect rotational force of the drive shaft 196 such that the rotational force of the drive shaft 196 can be transferred to the impeller shaft 198 in either clockwise or counterclockwise directions. In such an embodiment, a single directional motor 24 can be implemented and the drive mechanism 192 can include a transmission that can deliver modified bi-rotational force from the drive shaft 196 to the impeller shaft 198. It is also contemplated that the impeller shaft 198 or other portions of the drive mechanism 192 of the cooking and processing appliance 10 can include various gearing mechanisms that can be used to increase or decrease the rotational speed of the stirring mechanism 16. Such mechanisms can be implemented where a single speed, variable speed, one-directional or bi-directional motor 24 is used.

Where a single-speed motor 24 is used, the single speed motor 24 delivers a single amount of rotational force to the impeller shaft 198. The impeller shaft 198 can then include various gearing mechanisms that can be modified to transfer the single amount of rotational force from the motor 24 into various rotational forces and speeds that are delivered to the stirring mechanism 16.

In various alternate embodiments, it is contemplated that the motor 24 disposed within the cooking and processing appliance 10 can include a multi-speed motor 24 that can simply be modified through use of the user interface 120 to deliver different rotational speeds and forces from the drive shaft 196 to the impeller shaft 198 and into the stirring mechanism 16 of the container 12.

Referring now to the embodiment illustrated in FIG. 24, the drive transfer mechanism 194 that extended between the drive shaft 196 and the impeller shaft 198, the drive transfer mechanism 194 can include a belt, chain, shaft, gear train, or other similar drive transfer apparatus. In embodiments implementing a drive belt or drive chain, the inward surface of the belt or chain can include a surface that matingly engages an outer surface of both the drive shaft 196 and impeller shaft 198 to prevent slippage of the drive chain or drive belt, as the drive transfer mechanism 194 transfers the rotational force from the drive shaft 196 to the impeller shaft 198. According to various embodiments, the drive transfer mechanism 194 can include a V-belt, or similar timing belt, that includes a plurality of teeth disposed on an inner surface of the timing belt that engage an outer surface of both the drive shaft 196 and impeller shaft 198 to prevent slippage of the timing belt during operation of the drive transfer mechanism 194. The timing belt can also include a substantially trapezoidal cross section where an outer surface of the timing belt is wider than the inner toothed surface of the timing belt. Various reinforcement layers can be disposed within portions of the timing belt to strengthen the timing belt and prevent stretching or other deformation of the timing belt during extended use of the life of the cooking process and appliance. According to various embodiments, the drive shaft 196 can include a drive wheel 214 and the impeller shaft 198 can include an impeller wheel 216, where each of the drive wheel 214 and the impeller wheel 216 include various recesses that are configured to receive at least a portion of the teeth disposed on the inner surface of the timing belt. In this manner, the recesses of the drive and impeller wheels 214, 216 matingly cooperate with the teeth of the timing belt to prevent slippage of the timing belt during operation of the drive transfer mechanism 194.

Referring now to the embodiment illustrated in FIGS. 25-31, the cooking and processing appliance 10 can include a food processing insert 220 that can be disposed within the interior volume 28 of the container 12. The food processing insert 220 can be in the form of a basket that includes a platform 222 and a perimeter wall 224 that extends upward from the platform 222. According to the various embodiments, the food processing insert 220 is configured to be disposed within the interior volume 28 of the container 12 such that the bottom 226 of the chute 60 that extends downward form the lid 14 is disposed proximate a portion of the food processing insert 220. It is also contemplated that the food processing insert 220 can work in conjunction with a food slicing attachment 228 that can be disposed on the drive shaft 196 of the stirring mechanism 16. The food slicing attachment 228 can include an elongated central shaft 230 that extends through a central portion 232 of the food processing insert 220 to extend over at least a portion of the drive shaft 196. The food processing attachment 18 can also include an upper mount 234 that extends over at least a portion of the central portion 232 of the food processing insert 220. In this manner, the food processing insert 220 and the food processing function cooperate to define a food processing functionality positioned within the interior volume 28 of the container 12.

Referring again to the embodiment illustrated in FIGS. 25-31, it is contemplated that the food slicing attachment 228 can be used either with or without the food processing insert 220. Where the food processing insert 220 is included, foods that are disposed through the chute 60 of the lid 14 and pressed downward by the pusher 62 are sliced by the food slicing attachment 228, where the sliced food items can be caught by the platform 222 of the food processing insert 220. It is also contemplated that foodstuffs can be placed directly into the food processing insert 220 by opening the lid 14 and placing items within the food processing insert 220. The foodstuffs within the food processing insert 220 can then be poured directly into the interior volume 28 of the container 12 for further processing by the heating and stirring functions of the cooking and processing appliance 10. It is also contemplated that the food slicing attachment 228 can be used without the food processing insert 220. In this configuration, as foods are pushed down the chute 60 to be sliced by the food processing attachment 18, the foods that are sliced are disposed directly into the interior volume 28 of the container 12 to be immediately manipulated through the heating and stirring functions of the cooking and processing appliance 10.

Referring again to the embodiment illustrated in FIGS. 25-31, the interior volume 28, along with the various attachments and inserts, including the food processing insert 220, can define various zones within the interior volume 28 of the container 12. The lowest portion of the interior volume 28 can define a heating/stirring zone 240 of the interior volume 28 where the primary heating and stirring functions of the cooking and processing appliance 10 can take place. Above this lowest zone can be disposed a food processing zone 242 where the food processing insert 220 can be positioned to receive various sliced foods that are disposed down the chute 60 and manipulated by the food processing attachment 18. It is contemplated that other zones can be defined within the container 12 where such zones can include, but are not limited to, a pouring zone, a measuring zone, a steam zone 244 for inserting a steamer insert 246, and other various zones. It is contemplated that two or more of these zones can be utilized simultaneously through the use of two or more separate food processing attachments 18 placed in a stacked configuration. Where two or more food processing attachments 18 are utilized simultaneously, a gear reduction mechanism or other similar rotation modification device can be implemented so that each of the food processing attachments 18 can rotate at different speeds, in different directions, or both.

Referring now to FIGS. 25-33, it is contemplated that the cooking and processing appliance 10 can include a mini-bowl insert 248 having a separate set of mini-processing attachments 250 that can be engaged with the stir-assist interlock 132. The mini-bowl insert 248 can be used for smaller batches of food such as for fondue or heating chocolate or other small-batch food items. It is also contemplated that the mini-bowl insert 248 can include various utensils 252, such as fondue forks, spoons, tongs and others for use with the mini-bowl insert 248. Additionally, the mini-bowl insert 248 can include a splash guard 254 that can be used with the utensils 252 and the mini-bowl insert 248. When used, the mini-bowl insert 248 can utilize residual heat from the heating structure 26 within the container 12 for melting food items such as cheese or butter, or to temper various items such as chocolate.

According to the various embodiments, the container 12 of the cooking and processing appliance 10 can include a stainless steel outer wall 50 and base 52. Various alternate materials can be used in the construction of the container 12 that can include, but are not limited to, other metals, metal alloys, ceramics, various heat conducting materials, combinations thereof, and other similar heat conducting-type materials. It is also contemplated that the container 12 can include a heat conductive inner wall 110 that is configured to transfer heat from the conductive heating element 150 into the inner wall 110 of the container 12. Additionally, the container 12 can include a non-conductive outer wall 50 that is configured to contain heat within the inner wall 110 and allow a user to touch the exterior surface 102 of the outer wall 50 of the container 12 for moving the container 12 from one position to another. The housing 20 of the cooking and processing appliance 10 can be made of any one of various materials that can include, but are not limited to, plastic, metal, ceramic, alloys, composite materials, combinations thereof, and other similar materials that can be used to retain the container 12 and also be used in conjunction with the various heating and stirring functions of the cooking and processing appliance 10. As discussed above, the receptacle 22 of the housing 20 can include a heat shield 154 that provides an at least partial thermal barrier between the base 52 of the container 12, where the conductive heating element 150 is located, and the various mechanical portions of the housing 20, including the impeller shaft 198, drive transfer mechanism 194, motor 24, drive shaft 196, and the various electrical mechanisms of the cooking and processing appliance 10.

Referring now to the embodiment illustrated in FIGS. 34-41, the cooking and processing appliance 10 can include a lid interlock mechanism 260 that is configured to selectively engage the stirring mechanism 16 of the container 12. The lid interlock mechanism 260 can extend between the operable lid 14 and the stirring mechanism 16 of the container 12. The lid interlock mechanism 260 can include elongated members 262 that extend from an area proximate a hinge 144 of the lid 14 down to the base 52 of the container 12. As the lid 14 operates from the open position 56 to the closed position 38, the elongated members 262 operate downward 269 and engage interlock tabs 266 that extend at least partially into the base 52 of the container 12. When the lid 14 is moved to the open position 56 and the elongated members 262 are moved upward according to an upward biasing force 270 caused by lower ends 268 of the elongated members 262 that bias the interlocking tabs in an outward direction and away from the container 12 and out of engagement with the stirring mechanism 16 of the container 12. Accordingly, when the lid 14 is opened, the elongated members 262 cause a disengagement of the interlock tabs 266 from the stirring mechanism 16, thereby deactivating the stirring mechanism 16 such that the stirring functions of the cooking and processing appliance 10 are substantially inoperable. When the lid 14 is returned to the closed position 38, the elongated members 262 are extended downward 269 and the upward biasing force 270 placed on the interlock tabs 266 is substantially overcome such that the interlock tabs 266 are allowed to extend inward and into engagement with the stirring mechanism 16 of the container 12. In this manner, the movement of the lid 14 to the closed position 38 operates to extend the interlock tabs 266 inward to activate the stirring mechanism 16 of the appliance so that the various stirring functions of the cooking and processing appliance 10 can be operated. It is contemplated that the lid interlock mechanism 260 can be at least partially concealed by an interlock chase 274 that extends from proximate the hinge 144 of the lid 14 down to the base 52 of the container 12.

Referring again to the embodiment illustrated in FIGS. 34-41, it is contemplated that the lid interlock mechanism 260 can include upwardly biased elongated members 262 that are pressed downward 269 against the upward biasing force 270 when the lid 14 is in the closed position 38. The lower ends 268 of each of the elongated members 262 are hingedly coupled to the interlock tabs 266. The hinged connection 272 between the elongated members 262 and the interlock tabs 266 serves to force the interlock tabs 266 inward and into engagement with the stirring mechanism 16 when the lid 14 is moved into the closed position 38. Alternatively, when the lid 14 is moved to the open position 56, the upward biasing force 270 exerted upon the elongated members 262 forces the elongated members 262 in the upward direction. In this manner, the hinged connection 272 between the elongated members 262 and the interlock tabs 266 pulls the interlock tabs 266 away from the stirring mechanism 16 as the elongated members 262 are biased upward due to the upward biasing force 270.

According to the various embodiments, as exemplified in FIGS. 34-41, the inward and outward operation of the interlock tabs 266 as the lid 14 is moved between the closed and opened positions, respectively, can engage various portions of the stirring mechanism 16 and/or the drive mechanism 192 of the cooking and processing appliance 10. According to various embodiments, the interlock tabs 266 can engage a portion of the electrical system 152 of the cooking and processing appliance 10 to regulate the flow of electricity to the motor 24 for operating the various stirring functions of the cooking and processing appliance 10. Alternatively, the insertion of the interlock tabs 266 can engage a portion of the impeller shaft 198 to temporarily disengage the impeller shaft 198 from the stirring mechanism 16 to prevent operation of the various stirring functions of the cooking and processing appliance 10.

According to the various embodiments, it is contemplated that the lid interlock mechanism 260 can be used to activate and deactivate, primarily, the stirring functions of the cooking and processing appliance 10 such that when the lid 14 is in the open position 56, the stirring mechanism 16 cannot be activated and the various stirring and food processing functions of the stirring mechanism 16 cannot be engaged. According to the various embodiments, it is contemplated that the various heating functions of the cooking and processing appliance 10 may not be placed in communication with the lid interlock mechanism 260 such that the user can move the lid 14 between open and closed positions 56, 38 and continue to operate the various heating functions of the cooking and processing appliance 10. According to various alternate embodiments, it is contemplated that the lid interlock mechanism 260 can cause activation and deactivation of all cooking and heating functions of the cooking and processing appliance 10 such that when the lid 14 is moved to the open position 56, the heating functions and stirring functions are both temporarily disabled until such time as the lid 14 is moved back to the closed position 38.

Referring again to the embodiment illustrated in FIGS. 18-19 and 34-41, in order to maintain the interlock tabs 266 in the inserted position 280 for activation of the stirring and/or heating functions of the cooking and processing appliance 10, the lid 14 can include the lid latch 80 to secure the lid 14 in the closed position and to also maintain the elongated members 262 in a downward 269 position and the interlock tabs 266 in an inserted position 280. In this embodiment, it is contemplated that the release of the lid latch 80 will cause the lid 14 to move upward minimally. This minimal movement can be a result of the release and general upward 85 biasing tendency of the outwardly extending and tapered configuration of the folding portion 83 of the tight-fitting seal 82 disposed on the lid 14. The release of the lid latch 80 can result in the unfolding of the folding portion 83 of the seal 82, thereby resulting in the upward 85 biasing of the lid 14. This minimal movement of the lid 14, due to the release of the lid latch 80, can result in the elongated members 262 moving upward a sufficient distance and the interlock tabs 266 being moved outward a sufficient distance to deactivate the stirring and/or heating functions of the cooking and processing appliance 10.

Referring again to the embodiment illustrated in FIGS. 34-39, it is contemplated that the lid interlock mechanism 260 can include a plurality of elongated members 262 that are engaged with a plurality of corresponding interlock tabs 266. It is contemplated that each elongated member 262 and each interlock tab 266 pair, forming a dedicated interlock 148, can be configured to provide a different interlock feature. By way of example, and not limitation, one of the interlock tabs 266 can be configured to extend further into the receptacle 22, such that a minimal movement of the lid 14 will only move the elongated member 262 of the dedicated interlock 148 vertically only a small distance. This minimal movement of one of this elongated member 262 can be configured to translate only into a minimal outward movement of the corresponding interlock tab 266 of the dedicated interlock 148. In this manner, if the lid 14 were to become ajar, but not open completely, an interlock tab 266 that extends farther into the receptacle 22 may still be disposed at least partially within the receptacle 22 to prevent deactivation of certain functions of the cooking and stirring functions of the cooking and processing appliance 10.

Referring again to FIGS. 34-39, it is contemplated that the interlock tab 266 of another separate dedicated interlock 148 may be configured to extend a lesser distance into the receptacle 22 such that a minimal movement of the lid 14, such as when the lid 14 becomes ajar, will serve to fully remove the shorter interlock tab 266 completely from the receptacle 22. In this manner, when the lid 14 moves even the minimal distance, such as when the lid 14 becomes ajar, the shorter interlock tab 266 will be completely removed from the receptacle 22 and certain heating and/or stirring functions of the cooking and processing appliance 10 may be deactivated. It is contemplated that such a configuration can be used to distinguish between certain stirring functions, such as between high-speed stirring functions and low-speed stirring functions.

By way of example, and not limitation, if the lid 14 becomes ajar, a slow-speed stirring function such as a slow stir of a food item, or other prepared food may continue. However, if the lid 14 were to become ajar, high-speed functions such as food processing functions, along the line of slicing, dicing, and other similar food processing functions could be deactivated until such time as the lid 14 was fully secured onto the container 12 and the lid latch 80 fastened.

According to the various embodiments, the lid interlock mechanism 260 can include additional elongated member 262 and interlock tab 266 pairs that can be used to form a plurality of dedicated interlocks 148 that can activate and deactivate various heating and stirring functions of the cooking and processing appliance 10 when the lid 14 is moved in various positions between the open and closed positions of the lid 14. Such dedicated interlocks 148 can include a pouring interlock, an ingredient interlock, as well as others.

As discussed above, the lid interlock mechanism 260 and one or more of the dedicated interlocks 148 thereof can operate in concert with other interlock mechanisms, including the stir-assist interlock 132 contained within the lid arm 140 of the lid 14. It is also contemplated that one or more of the various interlock devices can be temporarily disabled when certain functions of the cooking and processing appliance 10 are used. As exemplified in FIGS. 25-33, when the mini-bowl insert 248 is being used, or in other cooking situations, it may be desirable to temporarily remove the lid 14 to provide more convenient access to the interior volume 28. When the lid 14 is removed, in various embodiments, all stirring functions or certain stirring function of the cooking and processing appliance 10 may be completely disabled until such time as the lid 14 is at least reattached. It is also contemplated that when the lid 14 is removed for the performance of such functions, one or more interlock mechanisms may be disabled through an interlock override disposed within the cooking and processing appliance 10. In various embodiments, when the lid 14 is removed, it is contemplated that all stirring functions of the cooking and processing appliance 10 can be completely disabled or at least partially disabled. Such disabling or partial disabling of the stirring functions can continue until such time as the lid 14 is reattached to the container 12.

Referring now to the embodiment illustrated in FIGS. 42-50, the cooking and processing appliance 10 can also include a container locking mechanism 310 that is defined between the engagement of the base 52 of the container 12 and the receptacle 22 of the housing 20. The container locking mechanism 310 can include one or more outwardly biased locking tabs 312 that include an at least partially sloped surface 314 that is configured to engage a portion of the base 52 of the container 12. As the container 12 is moved onto the receptacle 22, the base 52 of the container 12 engages the sloped surface 314 of the locking tabs 312 and biases the tabs inward against the outward biasing force 316. The base 52 of the container 12 includes a retaining recess 318 (shown in FIG. 45) that is positioned just above the lowest portion of the base 52 of the container 12. As the container 12 is disposed fully within the receptacle 22, the outwardly biased locking tabs 312 disposed within the container 12 locking mechanism are allowed to be biased outward to enter the retaining recesses 318 of the container 12. In this manner, the engagement between the locking tabs 312 of the housing 20 and the retaining recesses 318 of the container 12 cooperate to substantially secure the container 12 onto the receptacle 22 of the housing 20. Once secured, the container 12 is substantially held in place relative to the housing 20 such that the various cooking and stirring functions of the cooking and processing appliance 10 can be performed. It is contemplated that a second interlock mechanism can be placed in communication with the container locking mechanism 310 such that the various heating and stirring functions of the cooking and processing appliance 10 can be activated only when the container 12 is properly positioned on the receptacle 22 and the locking tabs 312 of the housing 20 are properly disposed within the retaining recesses 318 of the container 12. In this manner, when the container 12 is removed from the receptacle 22, the heating and stirring functions of the cooking and processing appliance 10 are deactivated and rendered substantially inoperable.

According to various embodiments, positioning the container 12 on the receptacle 22 can cause the locking tabs 312 of the housing 20 to be substantially engaged within the retaining recesses 318 of the container 12. This alignment between the locking tabs 312 and retaining recesses 318 can be configured to properly position the container 12 relative to a container interlock mechanism to activate the heating and stirring functions of the cooking and processing appliance 10 so that the control 40 can be used to operate the various cooking and stirring functions.

Referring now to FIGS. 2, 3 and 42-50, the housing 20 can include a container release mechanism 124, such as a lever 322, that can be used to move the locking tabs 312 inward and against the outward biasing force 316 of the container locking mechanism 310. In this manner, the locking tabs 312 can be removed from the retaining recesses 318 of the container 12 such that the container 12 can be released from the receptacle 22 of the housing 20.

According to various alternate embodiments, the container release mechanism 124 can be disposed on a portion of a container 12 such that as the user lifts the container 12, the user can engage the container release mechanism 124 to lift the container 12 from the receptacle 22 of the housing 20. In such an embodiment, it is contemplated that the release lever disposed upon the container 12 can be disposed proximate one of the handles 100, or both of the handles 100. Accordingly, as the user lifts the container 12, the user can conveniently engage the lever 322 and lift the container 12 at the same time, to conveniently release the container 12 from the receptacle 22 of the housing 20.

Referring again to the embodiments illustrated in FIGS. 42-50, the engagement between the container 12 and the receptacle 22 of the housing 20 can include additional mating features that are designed to substantially secure the container 12 onto the receptacle 22 of the housing 20. It is contemplated that the base 52 of the container 12 can include various ribs 340, slots 342, or other physical features that can engage cooperating slots 342, ribs 340 or other mating physical features disposed within the receptacle 22 of the housing 20. Such physical features can be used to properly align the container 12 onto the receptacle 22, such that as the container 12 is placed upon the receptacle 22, the locking tabs 312 of the housing 20 can be properly aligned with the retaining recesses 318 of the container 12.

Referring again to the embodiment illustrated in FIGS. 42-50, it is also contemplated that the container 12 can include terminals 350 that are configured to extend within a portion of the receptacle 22 where the terminals 350 are configured to engage the electrical system 152 of the housing 20 to deliver electrical power from the housing 20 to the conductive heating element 150 contained within the base 52 of the container 12. It is contemplated that the terminals 350 can be used to also deliver electrical power to various user controls 40 that may be disposed upon a container 12 or the lid 14 of the container 12, as may be the case in various embodiments. It is contemplated that the base 52 of the container 12 can include one or more terminals 350 that extend into cooperative mating terminal apertures 352 disposed within the receptacle 22. It is contemplated that the terminal apertures 352 extend downward into the receptacle 22 and engage an electrical contact 354 defined within a portion of the housing 20. In this manner, when the container 12 is disposed upon a receptacle 22 and secured thereto, the lower portion of the terminals 350 of the container 12 extends downward into the receptacle 22 and engages the electrical contact 354 disposed within the receptacle 22 of the housing 20. The engagement between the electrical contact 354 and the terminals 350 is configured to deliver electrical power to the various electrical functions of the container 12. Additionally, one or more terminals 350 can be used to transfer information and data related to the container 12 from the container 12 back into the housing 20, and vice versa, to be displayed on various portions of the user interface 120. Such information can include, but is not limited to, the temperature of the interior volume 28 of the container 12, the temperature of the various food items contained within the interior volume 28, weight information in embodiments where a scale is disposed within a portion of the container 12, and other various information related to the container and items placed within the interior volume 28 of the container 12.

Referring to the embodiments illustrated in FIG. 7, the cooking and processing appliance 10 can include a master power switch 360. The power switch 360 is configured to turn on or off all electrical power to the cooking and processing appliance 10. It is also contemplated that the cooking and processing appliance 10 can include a power cord (not shown) and related cord wrap for consolidating or storing the power cord.

Referring now to the embodiment illustrated in FIGS. 9-11 and 43, the receptacle 22 of the housing 20 can also include thermal redundant fuses 370 that are disposed within a metal cap 372 that extends from the receptacle 22 and are configured to engage a bottom surface 496 of the base 52 of the container 12. When the container 12 is positioned on the receptacle 22, the thermal redundant fuses 370 are configured to contact an adjacent surface 122 to a heater of the cooking and processing appliance 10 such as a tubular heating element 376, like a Calrod® heater.

Referring now to the embodiment illustrated in FIG. 44, the heating assembly contained within the base 52 of the container 12 can include a tubular heating element 376, such as a Calrod® heater. In such an embodiment, the tubular heating element 376 can be disposed proximate a heater plate 378 that extends adjacent to the tubular heating element 376, such that heat energy radiating from the tubular heating element 376 can be dispersed through the heater plate 378 and evenly throughout the base 52 of the container 12. In this manner, heat can be substantially evenly distributed throughout the heating/stirring zone 240 of the interior volume 28 of the container 12. It is also contemplated that the heater plate 378, or portions of the heater plate 378, can extend upward and along a portion of the inner or outer wall 50 of the container 12 to deliver heating along the sides of the interior volume 28 of the container 12. It is contemplated that the heater plate 378 can have a thickness of approximately 3 millimeters and can be made of various materials, including, but not limited to, aluminum, other metals, ceramic, combinations thereof and other heat-conductive materials.

According to the various embodiments, the thermal redundant fuses 370 housed within the metal cap 372 of the receptacle 22 are adapted to contact the heater plate 378 or other contact surface adjacent to the tubular heating element 376 such that the thermal redundant fuses 370 can act as an interlock between the container 12 and the receptacle 22 for interrupting the heating functions of the cooking and processing appliance 10 when the container 12 is removed from the receptacle 22. Alternatively, when the container 12 is disposed upon the receptacle 22, the contact surface of the heater plate 378 positioned adjacent to the tubular heating element 376 engages the thermal redundant fuses 370 and activates the heating functions of the cooking and processing appliance 10 such that the tubular heating element 376 can receive electrical power from the electrical system 152 of the housing 20 and perform the heating functions of the cooking and processing appliance 10.

Referring now to the embodiments illustrated in FIGS. 45-47, the various interlock features disposed within portions of the receptacle 22 of the housing 20 can be disposed proximate a flow channel 390. In this manner, where fluid, food particles, and other debris may be disposed proximate the receptacle 22, these particles can move through the various flow channels 390 of the housing 20 and away from the interlock portions 392 of the receptacle 22 such that the functioning of the various interlock portions 392 of the receptacle 22 is not interrupted by the deposition of various debris proximate the interlock portions 392 of the receptacle 22. The flow channel 390 can be defined by a recess disposed within a portion of the housing 20 proximate an interlock portion 392 of the receptacle 22. Additionally, the interlock portions 392 of the receptacle 22 can be raised above the flow channel 390, such that deposited debris tends to move downward, through the force of gravity, and into the flow channel 390, such that the debris can be moved away from the interlock portions 392 of the receptacle 22 of the housing 20. The flow channel 390 being disposed below the interlock portions 392 of the receptacle 22 prevents puddling and accumulation of other debris proximate the interlock portions 392 of the receptacle 22 of the housing 20. By way of example, and not limitation, it is contemplated that the locking tabs 312 that engage the base 52 of the container 12 are positioned above a dedicated flow channel 390 positioned below the locking tabs 312. Additionally, interlock tab contacts 394 disposed within the receptacle 22 and which are configured to receive interlock tabs 266 of the lid interlock mechanism 260 can be positioned above a separate and dedicated flow channel 390 that may be deposited proximate these connections.

According to the various embodiments, once the various cooking and stirring functions of the cooking and processing appliance 10 are complete, the container 12 can be removed from the receptacle 22 and the flow channels 390 can be easily cleaned to remove debris that may be deposited therein. Again, the debris is deposited within the flow channels 390 and is moved downward and away from the various interlock portions 392 and connection portions of the receptacle 22 of the housing 20.

Referring now to the embodiment illustrated in FIGS. 48-50, the container release mechanism 124 disposed within the housing 20 can be configured to engage one or more locking tabs 312 of the container locking mechanism 310. According to the various embodiments, the container release mechanism 124 is connected to a twist ring 410 disposed within the housing 20 proximate the receptacle 22. When the container release mechanism 124 is operated, the twist ring 410 rotates within the receptacle 22. One or more biasing members 412, such as springs, are configured to bias at least the twist ring 410 toward an engagement position 414. The engagement position 414 of the twist ring 410 is defined by the outward positioning of each of the locking tabs 312 of the receptacle 22. When the container release mechanism 124 is operated, the twist ring 410 rotates at least partially and moves toward a disengagement position 416. In the disengagement position 416, portions of the twist ring 410, proximate each of the locking tabs 312, bias the locking tabs 312 inward so that the container 12 can be released from the receptacle 22. Because the ring engages each of the locking tabs 312, the movement of the twist ring 410 between the engagement and disengagement positions, operates to simultaneously move each of the locking tabs 312 inward so that the container 12 can be disengaged through the movement of a single lever. Because the twist ring 410 extends substantially around an outer portion 430 of the receptacle 22, the twist ring 410 does not substantially interfere with the various stirring functions of the cooking and processing appliance 10. Accordingly, the impeller shaft 198 is configured to extend upward and through a central post 418 disposed proximate the twist ring 410. It is contemplated that the twist ring 410 can be supported by the central post 418 that also defines a grommet 420 through which the impeller shaft 198 can extend to engage the stirring mechanism 16 of the container 12. The central post 418 provides a structural support for the twist ring 410 and the container release mechanism 124. At the same time, the grommet 420 defined within the central post 418 provides a path through which the impeller shaft 198 can extend to engage the stirring mechanism 16.

According to the various embodiments, the container release mechanism 124 can be engaged by any one of various user interface mechanisms that can include, but are not limited to, levers 322, buttons, dials, triggers, motorized or automatic mechanisms, or other similar user interface mechanisms.

Referring now to the embodiment illustrated in FIG. 48, the electrical system 152 of the cooking and processing appliance 10 can include a main circuit board 422 disposed within the housing 20.

The main circuit board 422 can also include the logic that controls the various cooking and processing functions of the cooking and processing appliance 10.

Referring again to the embodiment illustrated in FIGS. 48-50, the container release mechanism 124 can extend from an outer portion 430 of the housing 20 to the grommet 420 disposed at the central post 418 of the receptacle 22, such that the rotational movement of the container release mechanism 124 can be supported by the grommet 420. In this manner, the container release lever 322 can rotate about the central post 418 that is disposed in a central area of a receptacle 22. The container release mechanism 124 can include an engagement portion 432 disposed within the receptacle 22 that engages the twist ring 410 and operates the twist ring 410 from the engagement to the disengagement position 416. The engagement portion 432 of the container release mechanism 124 can include a winding structure 434 disposed through a block assembly 436, where the winding structure 434 prevents rotation of the block structure during operation of the cooking and processing appliance 10. The winding structure 434 of the engagement portion 432 provides an upper surface 438 upon which a portion of the block assembly 436 can rest. Internal ribs 440 of the block assembly 436 can be positioned within the block assembly 436 and engage portions of the winding structure 434 of the engagement portion 432. It is contemplated that the block assembly 436 of the engagement portion 432 can engage a cutout 442 in the twist ring 410. In this manner, the block assembly 436 fits within the cutout 442. As the user operates the container release mechanism 124, the block structure engages the twist ring 410 proximate the cutout 442 and rotates the twist ring 410 about the central post 418 to move the twist ring 410 from the engagement position 414 to the disengagement position 416. Accordingly, the container release mechanism 124 and the twist ring 410 operate cooperatively about the central post 418 to manipulate the locking tabs 312.

Referring again to the embodiment illustrated in FIGS. 48-50, it is contemplated that the container locking mechanism 310 can include a locking pin 320 that engages a portion of the twist ring 410 to temporarily hold the twist ring 410 in the disengagement position 416. With the locking pin 320 holding the twist ring 410 in the disengagement position 416, the twist ring 410, in turn, temporarily holds the locking tabs 312 inward and out of engagement with the retaining recesses 318 of the container 12. In this temporary configuration, the container 12 can be conveniently removed from the receptacle 22 without the need to hold the lever 322 in position. As the container 12 is removed from the receptacle 22, a release tab 324 engages the locking pin 320 to release the twist ring 410 from its temporary engagement with the locking pin 320. The twist ring 410, as a result of the biasing members 412, is then returned to the engagement position 414 such that the locking tabs 312 are biased outward as a result of the outward biasing force 316. In various embodiments, the lever 322 is unaffected by the locking pin 320 such that the lever 322 automatically returns to its original position when the user releases the lever 322. It is also contemplated that the lever 322 can also be temporarily held in place by the locking pin 320 along with the twist ring 410.
