The present disclosure relates generally to a kitchen appliance configured to mix, process or blend foodstuff and, more particularly, to a blender or other such kitchen appliance that includes a relatively large jar for containing foodstuff and at least a relatively smaller container for containing foodstuff, wherein the jar and the at least one relatively smaller container are separately removably mountable to the base for blending and the blending of foodstuff contained therein may be accomplished by only a single motor.
Blenders are a relatively common household or kitchen appliance that are used to blend foodstuff, typically drinks or other foodstuff that is blended into a semi-fluid state. A typical blender includes a base enclosing a motor, a jar removably mounted to the base for containing the foodstuff and a lid to enclose the foodstuff within the jar. More recently, it has become popular to provide jars of various size and shape to accommodate a users needs in blending a variety of foodstuff. For example, certain blender bases, as seen in the food services industry, accommodate relatively large jars to blend large amounts of foodstuff at one time. Other types of blenders bases accommodate relatively small or portable containers or cups, such as a travel mug, to blend smaller amounts of foodstuff for individual or portable use.
However, such conventional blenders require two separate motors, one of which operates the blending blades of the jar and the other of which operates the blending blades of the small container. A resulting drawback is increased manufacturing costs and complexity.
Therefore, it would be desirable to provide an adapter that allow for simultaneous blending within a relatively large jar and/or a relatively small container by operation of just a single motor.
In one embodiment, the present disclosure is directed to an adapter for a blender including a base having a housing which encloses a motor. The housing has a top wall and an opposing bottom wall. The adapter includes a first drive shaft having a first clutch hub configured to be drivingly coupled to a first set of blending blades and a first pulley, the first clutch hub being positioned outside of the housing of the base of the blender; a second drive shaft having a first spline configured to be drivingly coupled to a second set of blending blades and a second pulley configured to be operatively coupled to the motor, the first spline being positioned outside of the housing of the base of the blender; and a belt which engages the first and second pulleys. The adapter is configured to be positioned proximate the top wall of the housing of the base of the blender. Operation of the motor causes rotation of the second pulley, the second drive shaft and the second set of blending blades. The rotation of the second pulley causes movement of the belt and the rotation of the belt, in turn, causes rotation of the first pulley, the first drive shaft and the first set of blending blades.
Another embodiment of the present disclosure is directed to a blender including a base having a housing, a motor enclosed within the housing and having a drive shaft with a motor clutch mounted on a distal end thereof, and first, second and third containers. Each of the first, second and third containers is provided with a first, second and third set of blending blades, respectively. The third container is of a different size than the first and second containers. The blender further includes an adapter having a first drive shaft drivingly coupled to the first set of blending blades, a second drive shaft drivingly coupled to the second set of blending blades, and a third drive shaft drivingly coupled to the third set of blending blades and the motor. The first, second and third drive shafts of the adapter are drivingly coupled to each other. Operation of the motor causes simultaneous rotation of the first, second and third drive shafts and the first, second and third sets of blending blades.
The foregoing summary, as well as the following detailed description of the disclosure, will be better understood when read in conjunction with the appended drawings. For the purpose of illustrating the disclosure, there are shown in the drawings embodiments which are presently preferred. It should be understood, however, that the disclosure is not limited to the precise arrangements and instrumentalities shown. In the drawings:

In another preferred embodiment (not shown), the adapter 14 is an integral component of the kitchen appliance 10 and is generally surrounded by the base housing 16 and positioned beneath the top wall 16a thereof together with the motor 13, the motor drive shaft 33 and the motor clutch 30. In such an embodiment, the adapter housing 64 and the base 12 are essentially integrally formed to provide the base housing 16 and the first, second and third recessed areas 66, 68, 70 are formed in the top wall 16a of the base housing 16.
The adapter 14 enables the relatively large jar 18 and the relatively small containers 20, 22 to be operatively connected to and operated by the single motor 13 of the kitchen appliance 10, as follows. Preferably, the first clutch hub 40 of the first drive shaft 48 is located within the first recessed area 66 and a complementary clutch 32 extends from a bottom surface of the first blending collar 24 to releasably engage the first clutch hub 40 of the first recessed area 66, as shown in FIGS. 1 and 5-6. Preferably, the second clutch hub 42 of the second drive shaft 50 is located within the second recessed area 68 and a complementary clutch 34 extends from a bottom surface of the second blending collar 26 to releaseably engage the second clutch hub 42 of the second recessed area 68, as shown in FIGS. 1 and 5-6. The first spline 58 of the third drive shaft 56 is preferably located within the third recessed area 70 and a bottom surface of the third blending collar 28 of the jar 18 includes a complementary spline hub 36 configured to releaseably engage the first spline 58 of the third recessed area 70, as shown in
As such, when the first and second containers 20, 22 and the jar 18 and the associated first, second and third blending collars 24, 26, 28 are properly mounted onto the base 12, as shown in
Preferably, the clutches 32, 34 and corresponding clutch hubs 40, 42 are made of a polymeric material, such as rubber or plastic. Preferably, the spline 58 and corresponding spline hub 36 are made of a metal. However, it will be understood by those skilled in the art that the clutches 32, 34 and corresponding clutch hubs 40, 42 and the spline 58 and corresponding spline hub 36 of the various connector mechanisms may be made of any appropriate materials, such as a metal, a polymeric material (e.g., rubber, plastic and the like), or a combination of such materials. It will be understood by those skilled in the art that the positions of the complementary clutches/clutch hubs and splines/spline hubs of the various connector mechanisms may be reversed. It will also be understood by those skilled in the art that any appropriate connector mechanism may be used in place of one or more of the various clutch and/or spline mechanisms described herein.
More particularly, in operation, the user places the base 12 onto the support surface, such as the countertop or tabletop, so that the base 12 support is flush with the support surface to provide stability to the kitchen appliance 10. Next, the user operatively connects the power cord of the base 12 to an electrical outlet in a conventional manner. At this point, the user has the option of using the jar 18 or one or both of the first and second containers 20, 22.
If the user desires that the blending operation requires the relatively large jar 18, the user mounts the third blending collar 28 into the bottom 18b of the jar 18 to close the bottom 18b (or the third blending collar 28 may already be mounted to or may be integrally formed with the bottom 18b of the jar 18). Then, the jar 18 can be mounted within the third recessed area 70 of the adapter housing 64 (if the adapter 14 is only an optional attachment accessory) or the appropriate recessed area of the base 12 to operatively connect the complementary spline hub 36 with the first spline 58.
Alternatively, if the user determines that a smaller amount of foodstuff will be blended, the user may choose to blend foodstuff within either or both of the containers 20, 22. In this configuration, the user will mount the first and/or second blending collars 24, 26 to the bottoms 20b, 22b of the first and/or second containers 20, 22, respectively (or the first and/or second blending collars 24, 26 may already be mounted to or integrally formed with the bottoms 20b, 22b). Then, the first and/or second containers 20, 22 can be mounted within the first and/or second recessed areas 66, 68, respectively of the adapter housing 64 (if the adapter 14 is only an optional attachment accessory) or the appropriate recessed areas of the base 12 to operatively connect the first clutch hub 40 with the complementary clutch 32 and/or to operatively connect the second clutch hub 42 with the complementary clutch 34.
Next, the user actuates the appropriate control button to commence operation of the motor. Operation of the motor 13 causes rotation of the motor drive shaft 33, the engaged motor clutch 30 and third clutch hub 54, the third pulley 52, the third drive shaft 56 and the engaged spline hub 36 and first spline 58, all of which, in turn, cause rotation of the third set of blending blades 29 (see
It will be appreciated by those skilled in the art that changes could be made to the embodiments described above without departing from the broad inventive concept thereof. It is understood, therefore, that this disclosure is not limited to the particular embodiments disclosed, but it is intended to cover modifications within the spirit and scope of the appended claims.
