Abstract

An apparatus for making a frozen dessert. The apparatus including a reservoir located within a chassis for receiving a liquid dessert mixture and a rotatable paddle located within the reservoir. The paddle can have a body coupled to at least one respective scraper element by a living hinge, such that the scraper element has a scraping edge that is radially-outward biased by the living hinge for abuttingly engaging a wall of the reservoir. The reservoir and the axis of rotation can be substantially horizontally directed, with a substantially vertically-orientated lid closing an opening of the reservoir, the lid defining an aperture for receiving the mixture or enabling egress of the frozen dessert.

First claim

The claims defining the invention are as follows:

1. An apparatus for making a frozen dessert, the apparatus including: a chassis; a reservoir located within the chassis for receiving a liquid dessert mixture to be cooled: a rotatable paddle located within the reservoir, the paddle being adapted to rotate about an axis within the reservoir; a drive motor for driving rotation of the paddle; a control module for controlling the drive motor to rotate the paddle; wherein the reservoir and the axis of rotation are horizontally directed; and the apparatus further including: a lid that closes an opening of the reservoir, the lid defining an aperture for receiving the mixture; and wherein the lid rotates with respect to a horizontal axis, such that the aperture can be directed upwardly to a fill configuration for receiving the mixture and directed downwardly to a dispense configuration for enabling egress of the frozen dessert.

2. The apparatus according to claim 1 , the apparatus further including:
a first sensor coupled to the control module for detecting if the lid is in the fill configuration or the dispense configuration.

3. The apparatus according to claim 2 , wherein the control module will control rotation direction of the paddle based on a detected lid configuration.

4. The apparatus according to claim 1 , the apparatus further including:
a second sensor coupled to the control module for detecting proximity of a vessel for receiving the frozen dessert.

5. The apparatus according to claim 1 , the apparatus further including:
a second motor controlled by control module, the second motor being coupled to the lid such that operation of the second motor enables rotation of the lid to either the fill configuration or the dispense configuration.

6. The apparatus according to claim 5 , the apparatus further including: a second sensor coupled to the control module for detecting proximity of a vessel for receiving the frozen dessert.

7. The apparatus according to claim 6 , wherein the control module will control rotation of the lid only when the vessel is detected.

8. The apparatus according to claim 5 , wherein the apparatus further includes: a dispense selector on a user interface for causing the second motor to rotate the lid to the dispense configuration; a user display that prompt a user to locate a suitable bowl for collection of frozen dessert.

9. The apparatus according to claim 5 , wherein the second motor is coupled to the lid by a belt drive that engages a circumferential surface defined about the perimeter of the lid.

10. The apparatus according to claim 5 , wherein the second motor is coupled to the lid by a gear drive that engages a circumferential gear defined about the perimeter of the lid.

11. The apparatus according to claim 1 , wherein the paddle has a body coupled to at least one respective scraper element by a living hinge, such that the scraper element has a scraping edge that is radially-outward biased by the living hinge for abuttingly engaging a wall of the reservoir.

12. The apparatus according to claim 1 , wherein off-axis camber of the scraper element and selective rotation direction of the paddle can cause the mixture to be directed toward or away from the base.

13. The apparatus according to claim 1 , wherein the control module will control rotation direction of the paddle to cause egress of the frozen dessert only when the vessel is detected.

14. The apparatus according to claim 1 , wherein the control module is networked to a least one other processor in a networked deployment.
