Definitions
- the present invention relates to ice cream making machines designed for personal or home use and, more particularly, to mixing paddle components used in such machines.
- ice cream making machines for personal or home use which share common characteristics including: small size, convenient storage and use, base with internal motor, freezing bowl, mixing paddle, and cover.
- the mixing paddle is placed in the bowl and moves relative to the bowl in either one of two arrangements. In the first, the bowl is in engagement with a drive mechanism that transfers rotational force from the motor to cause the bowl to rotate while the paddle is held stationary. In the other arrangement, the bowl is held stationary and the paddle is rotated relative to the bowl. Ice cream ingredients are placed in the bowl and the cover is positioned. As the mixing paddle and bowl move relative to each other the ingredients are cooled by the temperature of the pre-frozen bowl, resulting in ice cream.
- Known ice cream mixing paddles are designed to span a distance just short of the inner diameter of the mixing bowl so that direct contact is not made with the inner walls of the mixing bowl, as the friction plus the load of the ice cream might stall or damage the motor or paddle. At the same time, this prevents some of the ice cream mixture from being pushed into and out of contact with the cold inner wall of the bowl as much as the rest of the ice cream mixture.
- FIG. 1A is a front view of an ice cream maker used in accordance with the present invention.
- FIG. 1B is a top view of an ice cream maker used in accordance with the present invention.
- FIG. 1C is a bottom view of an ice cream maker used in accordance with the present invention.
- FIG. 1D is a rear view of an ice cream maker used in accordance with the present invention.
- FIG. 1E is a first side view of an ice cream maker used in accordance with the present invention.
- FIG. 1F is a second side view of an ice cream maker used in accordance with the present invention.
- FIG. 2 is an exploded view of an ice cream mixing paddle and ice cream maker according to and used in accordance with the present invention.
- FIG. 3A is a front view of an ice cream mixing paddle according to the present invention.
- FIG. 3B is a top view of an ice cream mixing paddle according to the present invention.
- FIG. 3C is a bottom view of an ice cream mixing paddle according to the present invention.
- FIG. 3D is a rear view of an ice cream mixing paddle according to the present invention.
- FIG. 3E is a first side view of an ice cream mixing paddle according to the present invention.

- FIG. 4A is a first perspective view of an ice cream mixing paddle according to the present invention.
- FIG. 4B is a top, cross-sectional view of and ice cream mixing paddle according to the present invention.
- FIG. 4C is an enlarged, top cross-sectional view of a contact edge of an arm of an ice cream mixing paddle according to the present invention.
- FIG. 5A is a second perspective view of an ice cream mixing paddle and a part-sectional, perspective view of a freezer bowl according to the present invention.
- FIG. 5B is a top view of an ice cream mixing paddle and freezer bowl according to the present invention.
- a mixing paddle for use in a conventional ice cream maker includes two vertical arms that have outer contact edges that exceed the inner diameter of the freezer bowl in which they are positioned during use. This enables the contact edges to effectively scrape ice cream ingredients from the inner wall of the bowl during use and direct the ingredients toward the center of the bowl.
- the mixing paddle also comprises two cross-members that have pin-wheel style shapes that move ice cream ingredients vertically during use. The combined effect of the vertical arms and the cross-members optimally and uniformly mixes the ice cream ingredients during use and ensures efficient cooling.
- an ice cream maker 1 comprises a base 2 and lid 3 .
- the lid 3 has an opening 4 at its top surface.
- the base 2 houses an internal motor and drive assembly (not shown) of a conventional type.
- the bottom surface of the base 2 includes vents 5 , 6 to accommodate cooling during the motor operation.
- a freezer bowl 7 is adapted to be mounted on the base 2 and a mixing paddle 8 is adapted to be positioned in the freezer bowl 7 .
- the lid 3 covers both the freezer bowl 7 and the paddle 8 .
- the mixing paddle 8 made of plastic or a material having similar properties, as shown in FIGS. 3A-3F , comprise a ring-shaped top portion 9 , a first longitudinal arm 10 , a second longitudinal arm 11 , an upper cross-member 12 , and a lower cross-member 13 .
- the top portion 9 includes internal ribs 14 , 15 , 16 to lock against rotation relative to the lid 3 when attached thereto.
- the longitudinal arms 10 , 11 are positioned at a relative distance to each other and aligned with the top portion 9 such that they are positioned generally coincident with the annular wall of the top potion 9 , except that the longitudinal arms 10 , 11 are each angled so as to be tangentially oriented with respect to the annular wall of the top portion 9 .
- the first arm 10 includes a longitudinally extending groove 35 adjacent to the contact edge 17 to enable it to flex primarily at the groove 35 when the contact edge 17 is in contact with the bowl's inner wall during use.
- a groove 36 exists on the second arm 11 of the same configuration and for the same purpose. This facilitates positive contact with the bowl during use as described below.
- the center hub 21 of the paddle 8 is part of the lower cross-member 13 and is positioned in alignment with the center of the circle formed by the top portion 9 .
- the lower cross-member 13 has a first side 22 and a second side 23 .
- the two sides 22 , 23 are out-of-plane and angled with respect to each other in the same manner as a pinwheel or propeller, with the hub 21 forming the center of rotation.
- the first side 22 has a leading edge 24 and a trailing edge 25 .
- the second side 23 has a leading edge 26 and a trailing edge 27 .
- the upper cross-member 12 has a first side 28 and a second side 29 separate from each other by a middle portion 30 .
- the first and second sides 28 , 29 are out-of-plane and angled with respect to each other in the same manner as a pinwheel or propeller, with the middle portion 30 forming the center of rotation.
- the first side 28 has a leading edge 31 and a trailing edge 32 .
- the second side 29 has a leading edge 33 and a trailing edge 34 .
- a user places the freezer bowl 7 into a freezer appliance or outside, if sufficiently cold outside, to cool the temperature of the freezer bowl 7 .
- the freezer bowl 7 may be of a type having a double-wall construction forming an internal compartment that is filled with cold-retention material such as liquid or gel that can be frozen. Once the freezer bowl 7 is cooled, it is positioned on the base 2 .
- the bowl 7 is positioned such that drive engaging means (not shown) on the bottom of the bowl 7 engage the drive output means 37 of the motor that are rotationally driven. This enables the bowl 7 to be rotated relative to the base 2 during operation.
- the paddle 8 is positioned in the bowl 7 such that the hub 21 rests on the bottom of the bowl 7 and the lid 3 is placed over the bowl 7 and mounted to the base 2 . Ice cream ingredients are added to the bowl 7 through the opening 4 . The ingredients immediately begin chilling.
- the bowl 7 begins to rotate relative to the base 2 .
- the lid 3 is fixed relative the base 2 and the paddle 8 is fixed relative to the lid 3 by attaching to the lid 3 at its top portion 9 .
- the bowl 7 rotates relative to the base 2 , to the lid 3 and to the paddle 8 .
- the relative movement between the bowl 7 and the paddle 8 causes the ice cream ingredients in the bowl 7 to be mixed and moved relative to the bowl 7 .
- the contact edges 17 , 18 are always in contact with the inner wall surface 38 of the freezer bowl 7 due to the flexibility of the contact edges 17 , 18 .
- This enables all of the ingredients to be more evenly mixed by the longitudinal arms 10 , 11 and moved into and out of contact with the inner wall surface 38 .
- the edges 17 , 18 move ingredients away from the inner wall surface 38 and towards the center of the bowl so that more ingredients can assume the position of contact with the wall surface 38 .
- the cycle repeats continuously during operation, As a result, uniform and efficient cooling of ingredients is achieved, as is optimal mixing.
- the upper and lower cross-members 12 , 13 move the ingredients vertically and laterally due to their pinwheel shapes and rotational movement. This vertical movement, combined with the above-described movement cause by the longitudinal arms 10 , 11 enhances the mixing and cooling.
