Device for chopping food, in particular pieces of ice
View Patent ↗A device for chopping food, including ice, has a container with a bearing pin on its bottom. The container is divided into an upper processing zone and a lower collecting zone. For reducing the food, the processing zone accommodates a chopping tool formed by a rotary cutting blade and a tool spindle. A sieve separates the processing zone from the collecting zone. The lower end of the tool spindle is rotatably mounted on the bearing pin. A stirring tool ( 34 ) may be provided which is part of the chopping tool and is formed by a rotary stirring blade.
1. A device for chopping food, said device comprising:
a container having an opening edge and a bottom and being divided into an upper processing zone, a transition region, and a lower collecting zone;
a bearing pin positioned on the bottom of the container; and
a tool spindle having a lower end and a rotary cutting blade for forming a chopping tool for reducing the food, said chopping tool being positioned in the upper processing zone; and
a sieve attached to a ring, wherein the ring is mounted on the opening edge of the container, wherein the sieve is in the transition region from the processing zone to the collecting zone for at least partially separating the upper processing zone from the lower collecting zone,
wherein the lower end of the tool spindle is rotatably mounted on the bearing pin.
2. The device according to claim 1 , wherein a bottom of the sieve includes an opening to accommodate the tool spindle.
3. The device according to claim 1 , wherein the lower end of the tool spindle has an elongated cavity for rotatably engaging with the bearing pin and allowing for pivotal movement about an axis of the bearing pin.
4. The device according to claim 3 , wherein the elongated cavity is provided with a bearing part, an inner surface of the bearing part having a predetermined shape for jamming with the bearing pin during pivotal movement.
5. The device of claim 4 , wherein the predetermined shape has a first width at a first end, a second width at a second end, and a third width between the first end and the second end; the first width, the second width and the third width being different from each other.
6. The device according to claim 1 , wherein the ring comprises elastic material.
7. The device according to claim 1 , wherein the bearing pin is made of metal.
8. The device according to claim 1 , further comprising a stirring tool in the collecting zone.
9. The device according to claim 8 , wherein the stirring tool is part of the chopping tool.
10. The device according to claim 8 , wherein the stirring tool is formed by a rotary stirring blade.
11. The device of claim 1 , wherein the lower end of the tool spindle has an elongated cavity with a width for rotatably engaging with the bearing pin, the width being variable along the elongated cavity.
12. The device of claim 11 , wherein the width decrease from both ends of the elongated cavity toward a middle of the elongated cavity.
13. The device of claim 11 , wherein the width is minimum near a lower end of the elongated cavity and increase towards the lower end and an upper end of the elongated cavity.
14. The device of claim 13 , wherein the width at the upper end of the elongated cavity is maximum.
15. The device of claim 1 , wherein the lower end of the tool spindle has an elongated cavity for rotatably engaging with the bearing pin and allowing for pivotal movement about an axis of the bearing pin for jamming with the bearing pin during pivotal movement.
16. The device of claim 15 , wherein the jamming leads to stopping of the crushing tool within substantially 1.5 seconds for a rotational speed of the crushing tool of up to substantially 15000 revolutions per minute.
