Abstract

The disclosure extends to apparatuses, methods, and systems, for producing frozen confections and conditioning ice for use in frozen confections. A frozen confection machine includes a hopper portion for receiving ice into an interior, and a motor configured to rotate a drive shaft, a blade to condition the ice in the hopper during rotation of the motor. The frozen confection machine also includes a lid for selectively covering the interior of the hopper, a bias member for biasing the lid away from a closed position, and a switch for causing the motor to actuate in response to the lid being pressed to a closed position.

Claims

1. A frozen confection machine comprising:

a hopper portion for receiving ice into an interior;

a motor connected to a drive shaft, such that upon actuation the motor rotates the drive shaft;

a blade to condition the ice in the hopper during actuation of the motor;

a lid for selectively covering the interior of the hopper;

a bias member positioned to bias the lid,

such that the lid rests in an at least partially open position; and

a switch for causing the motor to actuate in response to the lid being pressed to a closed position.

2. The frozen confection machine of claim 1, wherein the bias member provides a bias force greater than a force provided by a weight of the lid.

3. The frozen confection machine of claim 1, wherein an additional downward force on the lid is required to move the lid into a closed position and actuate the switch.

4. The frozen confection machine of claim 3, wherein the bias member causes the lid to return to the at least partially open position in response to removal of the additional downward force.

5. The frozen confection machine of claim 1, further comprising a plunger actuated by the lid, wherein the plunger is in mechanical communication with the switch when the lid is in or near the closed position.

6. The frozen confection machine of claim 1, comprising a bias switch, wherein the bias switch comprises the bias member and the switch.

7. The frozen confection machine of claim 1, wherein the hopper portion comprises a container rim and the lid comprises a lid rim, wherein the closed position comprises a position where the lid rim is at a substantially same height as the container rim or lower than the container rim.

8. The frozen confection machine of claim 1, wherein the hopper portion comprises a container rim and the lid comprises a lid rim, wherein the lid rests at a position with a non-zero vertical distance between a position of the container rim and the lid rim.

9. The frozen confection machine of claim 1, wherein the drive shaft drives a paddle in the interior of the hopper when rotated by the motor.

10. A portable ice conditioning machine comprising:

a container for receiving ice;

a motor for actuating a paddle or blade within the container;

a lid for selectively covering an interior of the container; and

a switch for causing the motor to actuate in response to the lid being pressed to a closed position; and

a bias member positioned to bias the lid,

such that the lid rests in an at least partially open position.

11. The portable ice conditioning machine of claim 10, wherein the bias member provides a bias force and wherein the bias force is greater than a force provided by a weight of the lid.

12. The portable ice conditioning machine of claim 10, wherein an additional downward force on the lid is required to move the lid into a closed position and actuate the switch.

13. The portable ice conditioning machine of claim 12, wherein the bias member causes the lid to return to the at least partially open position in response to removal of the additional downward force.

14. The portable ice conditioning machine of claim 10, further comprising a plunger actuated by the lid, wherein the plunger is in mechanical communication with the switch when the lid is in or near the closed position.

15. The portable ice conditioning machine of claim 10, wherein the bias member and the switch are contained in a bias switch.

16. The portable ice conditioning machine of claim 10, wherein the hopper portion comprises a container rim and the lid comprises a lid rim, wherein the closed position comprises a position where the lid rim is at a substantially same height as the container rim or lower than the container rim.

17. The portable ice conditioning machine of claim 10, wherein the hopper portion comprises a container rim and the lid comprises a lid rim, wherein the lid rests at a position with a non-zero vertical distance between a position of the container rim and the lid rim.

18. The portable ice conditioning machine of claim 10, further comprising a drive shaft in connection with the motor to drive the paddle.
