Abstract

A dust cover for a stand mixer bowl includes a disc-shaped body defining a central aperture therethrough and extending from the central aperture to an outer extent and a rim extending from the outer extent of the disc-shaped body to define an interior portion of the dust cover with the disc-shaped body. The interior portion of the dust cover is configured to removably receive an upper portion of a mixing bowl with the disc-shaped body extending inwardly from a lip of the mixing bowl positioned adjacent the outer extent of the disc-shaped body over at least a portion of an interior of the mixing bowl. The central aperture is configured for a portion of a planetary hub of a stand mixer to extend therethrough with an outer surface of the portion of the planetary hub adjacent an inner edge of the central aperture.

First claim

What is claimed is:

1. A mixing bowl assembly for use with a stand mixer, comprising:
a first mixing bowl including a body extending to a first lip and defining a first interior cavity;
a second mixing bowl including a second body extending to a second lip to define a second interior cavity, the second body of the second mixing bowl being received within the first mixing bowl with a second rim in supporting contact with the first lip of the first mixing bowl; and
a dust cover, including:
a disc-shaped body defining a central aperture therethrough and extending from the central aperture to an outer extent; and
a rim extending from the outer extent of the disc-shaped body to define an interior portion of the dust cover with the disc-shaped body;

wherein:
an upper portion of the first mixing bowl and an upper portion of the second mixing bowl are received within the interior portion of the dust cover, with the disc-shaped body extending inwardly from the second lip of the second mixing bowl positioned adjacent the outer extent of the disc-shaped body over at least a portion of an interior of the mixing bowl;
the rim of the dust cover extends away from the disc-shaped body to a first distance that is greater than a height of an upper lip of the mixing bowl such that a portion of the rim can engage with the first lip of the first mixing bowl over the second lip of the second mixing bowl; and
the central aperture is configured for a portion of a planetary hub of the stand mixer to extend therethrough into the interior cavity of the mixing bowl with an outer surface of the portion of the planetary hub adjacent an inner edge of the central aperture when the dust cover receives the upper portion of the mixing bowl and the mixing bowl is coupled to the stand mixer in a storage position thereof.

2. The mixing bowl assembly of claim 1 , wherein the mixing bowl includes a base configured for mounting with a bowl coupling of the stand mixer, the body of the mixing bowl extending from the base.

3. The mixing bowl assembly of claim 1 , wherein the dust cover is removable from the mixing bowl for use of the stand mixer in connection with the mixing bowl.

4. The mixing bowl assembly of claim 1 , wherein the central aperture of the dust cover is sized to correspond with an outer path of the surface of the planetary output hub through an operational range of motion thereof.

5. The mixing bowl assembly of claim 4 , wherein the central aperture is sized to be within an operational tolerance of the outer path of the surface of the planetary output hub within at least a portion of the operational range of motion thereof.

6. The mixing bowl assembly of claim 1 , wherein the outer surface of the hub is within about 3 mm of the inner edge of the central aperture when the mixing bowl is coupled with the stand mixer.

7. The mixing bowl assembly of claim 1 , wherein the central aperture has a radius of 40 mm.

8. The mixing bowl assembly of claim 1 , wherein an inner surface of the rim has a radius of 115 mm.

9. The mixing bowl assembly for use with a stand mixer of claim 1 , wherein:
a portion of the disc-shaped body rests on the second lip of the second mixing bowl with the rim extending downwardly past the second lip to engage with the first lip of the first mixing bowl; and
the rim of the dust cover defines a detent feature that is configured for a snap fit engagement over the first lip with the second lip captured between the first lip and a portion of the disc-shaped body adjacent the rim to retain the first and second mixing bowls in an assembly with the dust cover.

10. The mixing bowl assembly for use with a stand mixer of claim 1 , further including a third mixing bowl having a third body extending to a third lip to define a third interior cavity, the third body of the third mixing bowl being received within the second mixing bowl with a third rim in supporting contact with the first lip of the first mixing bowl; wherein:
an upper portion of the third mixing bowl is further received within the interior portion of the dust cover with the respective upper portions of the first and second mixing bowls; and
the first distance is further such that the portion of the rim can engage with the first lip of the first mixing bowl over the second lip of the second mixing bowl and the third lip of the third mixing bowl with the third lip in contact with a portion of the disc-shaped body.

11. A stand mixer, comprising:
a base including a bowl coupler;
a mixing head coupled with the base and including an output hub extending therefrom;
a first mixing bowl including a base removably coupled with the bowl coupler and a first body extending from the base to a first lip and defining a first interior cavity;
a second mixing bowl including a second body extending to a second lip to define a second interior cavity, the second body of the second mixing bowl being received within the first mixing bowl with the second rim in supporting contact with the first rim of the first mixing bowl; and
a dust cover, including:
a disc-shaped body defining a central aperture therethrough and extending from the central aperture to an outer extent; and
a rim extending from the outer extent of the disc-shaped body to define an interior portion of the dust cover with the disc-shaped body;

wherein:
respective upper portions of the first mixing bowl and second mixing bowl are received within the interior portion of the dust cover, with the disc-shaped body extending inwardly from the first lip of the first mixing bowl positioned adjacent the outer extent of the disc-shaped body over at least a portion of the first interior cavity of the first mixing bowl; and
the central aperture is configured for a portion of the planetary hub to extend therethrough into the interior cavity of the mixing bowl with an outer surface of the portion of the planetary hub adjacent an inner edge of the central aperture.

12. The stand mixer of claim 11 , further including a third mixing bowl having a third body extending to a third lip to define a third interior cavity, the third body of the third mixing bowl being received within the second mixing bowl with a third rim in supporting contact with the first lip of the first mixing bowl; wherein:
an upper portion of the third mixing bowl is further received within the interior portion of the dust cover with the respective upper portions of the first and second mixing bowls; and
the first distance is further such that the portion of the rim can engage with the first lip of the first mixing bowl over the second lip of the second mixing bowl and the third lip of the third mixing bowl with the third lip in contact with a portion of the disc-shaped body.
