Abstract

A stand mixer includes: a base, the base including a bowl lift framework having first lift features; a support arm attached to the base and extending upwardly therefrom; a head attached to an upper end of the support arm and extending generally horizontally therefrom above the base; and a bowl assembly comprising a bowl and a skirt mounted to the bowl, the skirt including second lift features. The first lift features interact with the second lift features such that, when the bowl assembly is rotated relative to the bowl lift framework, the bowl assembly changes elevation relative to the base between raised and lowered positions.

First claim

That which is claimed is:

1. A stand mixer, comprising:
a base, the base including a bowl lift framework having first lift features;
a support arm attached to the base and extending upwardly therefrom;
a head attached to an upper end of the support arm and extending generally horizontally therefrom above the base; and
a bowl assembly comprising a bowl and a skirt mounted to the bowl, the skirt including second lift features;
wherein the first lift features interact with the second lift features such that, when the bowl assembly is rotated relative to the bowl lift framework, the bowl assembly changes elevation relative to the base between raised and lowered positions.

2. The stand mixer defined in claim 1 , wherein the first features comprise one of a plurality of projecting nubs and a plurality of partially helical tracks, and the second features comprise the other of a plurality of projecting nubs and a plurality of partially helical tracks.

3. The stand mixer defined in claim 2 , wherein the first features comprise a plurality of partially helical tracks, and the second features comprise a plurality of radially-outwardly projecting nubs.

4. The stand mixer defined in claim 3 , wherein at least one of the projecting nubs is spring-loaded and biased toward a radially-outward extended position.

5. The stand mixer defined in claim 3 , wherein at least one of the partially helical tracks includes a pocket at an upper end thereof configured to retain one of the projecting nubs therein.

6. The stand mixer defined in claim 3 , wherein the plurality of partially helical tracks is three helical tracks.

7. The stand mixer defined in claim 6 , wherein each of the partially helical tracks extends circumferentially over an arc length of between about 80 and 100 degrees.

8. The stand mixer defined in claim 3 , wherein a respective recess is contiguous with a lower end of each partially helical track.

9. The stand mixer defined in claim 3 , wherein an upper end of each of the partially helical tracks is tapered.

10. The stand mixer defined in claim 1 , wherein the bowl includes a single handle.

11. The stand mixer defined in claim 10 , wherein rotation of the bowl between about 80 and 100 degrees moves the bowl between the raised and lowered positions.

12. The stand mixer defined in claim 1 , further comprising beaters rotatably mounted to the head and extending downwardly into the bowl.

13. The stand mixer defined in claim 12 , wherein the beaters are configured to rotate relative to the bowl in a first rotative direction, and wherein the bowl rises from the lowered position to the raised position when rotated in the first rotative direction.

14. A method of raising a bowl of a stand mixer, comprising:
providing a stand mixer having a base, a support arm attached to the base and extending upwardly therefrom, a head attached to an upper end of the support arm and extending generally horizontally therefrom above the base, beaters mounted on the head and extending downwardly therefrom, and a bowl mounted in the base below the beaters; and
rotating the bowl relative to the base, wherein features of the bowl interact with features of the base to cause the bowl to change in elevation relative to the base upon such rotation.
