Abstract

A spiralizer attachment for a stand mixer includes a base assembly connectable to an attachment drive port of the stand mixer and a cutting blade rotatably disposed in the base assembly. The spiralizer attachment further includes a lid including a feeding chute through which food can be delivered to the cutting blade.

First claim

What is claimed is:

1. A spiralizer attachment for a stand mixer comprising:
a base assembly connectable to an attachment drive port of the stand mixer;
a cutting blade rotatably disposed in the base assembly;
a lid including a feeding chute through which food can be delivered to the cutting blade;
a drive system adapted to drive the cutting blade in rotary motion within the base assembly; and
an actuation assembly configured to connect and disconnect the cutting blade from the drive system when the lid is attached to and detached from the base assembly, respectively.

2. The spiralizer attachment according to claim 1 , wherein the feeding chute extends vertically outward from a disc portion of the lid.

3. The spiralizer attachment according to claim 1 , wherein the feeding chute extends outwardly from a disc portion of the lid at a tilted angle.

4. The spiralizer attachment according to claim 3 , wherein the cutting blade is provided on a blade disc having an inverted cone-shaped body.

5. The spiralizer attachment according to claim 4 , wherein the feeding chute extends outwardly from the disc portion of the lid at an acute angle relative to a rotational axis about which the cutting blade rotates.

6. The spiralizer attachment according to claim 1 , wherein the drive system comprises:
a drive shaft connectable to the attachment drive port of the stand mixer;
a first gear coupled to the drive shaft; and
a blade holder supporting the cutting blade and rotationally coupled to the cutting blade, the blade holder comprising a ring gear formed in an outer surface of the blade holder;
wherein the actuation assembly brings the ring gear into and out of contact with the first gear coupled to the drive shaft.

7. The spiralizer attachment according to claim 6 , wherein the first gear is a conical gear; and
wherein the ring gear formed in the outer surface of the blade holder is a conical gear ring.

8. The spiralizer attachment according to claim 6 , wherein the lid comprises a plurality of sliding blocks receivable in corresponding chutes formed in the base assembly to couple the lid to the base assembly; and
at least one activation coupling tab adapted to engage the actuation assembly and cause actuation of the actuation assembly when the lid is coupled and decoupled from the base assembly.

9. The spiralizer attachment according to claim 8 , wherein the actuation assembly comprises:
a lift assembly slidably disposed within the base assembly; and
a rotational ring, the rotational ring slidably coupled to an upper end of the lift assembly such that rotation of the rotational ring causes lifting or lowering of the lift assembly within the base assembly;
wherein the rotational ring comprises at least one lid coupling slot, each lid coupling slot of the at least one lid coupling slot configured to receive an activation coupling tab of the at least one activation coupling tab of the lid.

10. The spiralizer attachment according to claim 9 , wherein the lift assembly includes an anti-rotation feature engaging a corresponding feature on the base assembly and preventing rotation of the lift assembly relative to the base assembly.

11. The spiralizer attachment according to claim 9 , wherein the lift assembly includes a shelf supporting the blade holder on the lift assembly.

12. The spiralizer attachment according to claim 11 , wherein rotation of the lid relative to the base assembly drives rotation of the rotational ring and lifting or lowering of the lift assembly and the blade holder to bring the ring gear into and out of contact with the first gear coupled to the drive shaft.

13. The spiralizer attachment according to claim 9 , wherein the base assembly comprises a lock that only allows rotation of the rotation ring when each activation coupling tab of the at least one activation coupling tab of the lid is received in a respective lid coupling slot of the at least one lid coupling slot.

14. The spiralizer attachment according to claim 13 , wherein the lock comprises a lock bar biased into one of the at least one lid coupling slot and displaceable from the one of the at least one lid coupling slot by an activation coupling tab of the at least one activation coupling tab.
