Abstract

A bench mixer has a combined whisk and scraper attachment. In preferred embodiments, the mixer has a processor configured to access data indicative of a respective power limit to be applied to a motor for each of a plurality of user selectable speed settings and monitors motor speed to compare against a user selected speed setting. The processor increases the power applied to the motor, up to a respective power limit if the current speed is lower than the user selected speed setting.

First claim

What is claimed is:

1. A scraper whisk apparatus for a mixer appliance, the scraper whisk apparatus being releasably couplable to the mixer appliance, the apparatus comprising:
a scraper element having one or more scraper arm portions, each scraper arm portion having a scraper blade portion;
a coupling assembly that is releasably couplable to the mixer appliance; and
a whisk cage element having a plurality of wire whisk elements; a first flange element and a second flange element couples respective ends of the plurality of wire whisk elements, such that each of the plurality of wire whisk elements starts at the first flange element and terminates at the second flange element;
wherein the scraper element has the coupling assembly for releasably coupling to the mixer appliance, and is separately releasably coupled to the whisk cage element.

2. The apparatus of claim 1 , wherein the scraper element comprises one or more a scraper arm portions, each scraper arm portions having a scraper blade portion.

3. The apparatus of claim 1 , wherein the scraper element comprises at least two scraper arm portions, each scraper arm portions having a scraper blade portion.

4. The apparatus of claim 3 , wherein a lower end of each of the at least two scraper arm portions are joined by a bridging portion.

5. The apparatus of claim 4 , wherein the bridging portion is located above a lower junction of the whisk cage element, such that the bridging portion does not contact the wire whisk elements.

6. The apparatus of claim 2 , wherein each scraper arm portions and scraper blade portion includes a substantially straight portion that is angled such that, in use with a mixture in a bowl, the top leads into the direction of rotation to direct mixture located on a bowl wall back down into the mixture.

7. The apparatus of claim 1 , wherein a domed portion is located under the coupling assembly to promote viscous debris to runoff.

8. The apparatus of claim 1 , the apparatus further including a central hub portion, wherein the coupling assembly is formed on the hub portion, and the scraper element comprising one or more a scraper arm portions that extend from the hub; and the whisk cage element being separately removably couplable to the hub portion.

9. The apparatus of claim 1 , the apparatus further including a central hub portion, wherein the coupling assembly is formed on the hub portion, and the scraper element comprising one or more a scraper arm portions are integrally formed with the hub portion, the whisk cage element being separately removably couplable to the hub portion.

10. The apparatus of claim 9 , wherein the hub further comprises a locking element for separately retaining the whisk cage element.

11. The apparatus of claim 10 , wherein the locking element is in the form of a locking collar threadedly engaged about the hub; and the first flange element and the second flange element abut the hub, such that rotation of the collar about the hub cause the collar to ride over and retain the whisk cage element.

12. The apparatus according to claim 1 , wherein a locking element is associated with the scraper element for retaining the whisk cage element.

13. The apparatus according to claim 12 , wherein the locking element is threadedly engaged to the scraper element and can be rotated to retain the whisk cage element.

14. The apparatus according to claim 13 , wherein the locking element is a collar located proximal to the coupling assembly.

15. The apparatus according to claim 14 , wherein the first flange element and the second flange element are each arcuate and sized to fit about the coupling assembly.

16. The apparatus according to claim 15 , wherein locking element is drawn down over the flange to retain the first flange element and the second flange element.

17. The apparatus according to claim 16 , wherein a lower end of each of the at least two scraper arm portions are joined by a bridging portion.

18. The apparatus according to claim 17 , wherein the bridging portion is located above a lower junction of the whisk cage element, such that the bridging portion does not contact the wire whisk elements.

19. The apparatus according to claim 11 , wherein the first flange element opposes the second flange element.

20. The apparatus according to claim 19 , wherein first flange element and the second flange element each have an ‘L’ shape cross section.

21. The apparatus according to claim 11 , wherein the first flange element and the second flange element are each in the form of an ‘L’ shaped arcuate flange.
