Dispensing mechanism for popcorn popper
The popcorn popper has an on-board storage compartment for storing un-popped kernels of corn. The un-popped kernels of corn may be directed from the storage compartment to cooking surfaces via a dispenser. The dispenser provides a desired serving size of kernels and includes a mechanism to prevent overfeeding of the popper.
1. A hot air popcorn popper comprising
a heating element and a blower fan;
a cooking surface adapted to receive kernels of corn;
a popping chamber into which popcorn enters after being popped, the popping chamber having an inlet and an outlet, the popping chamber inlet being adjacent to the cooking surface, the popping chamber outlet being spaced from the popping chamber inlet;
a seed storage compartment configured to receive kernels of un-popped corn;
a dispenser configured to move between a receiving position and a dispensing position, in the receiving position, the dispenser receiving kernels of un-popped corn from the seed storage compartment, and in the dispensing position, the dispenser dispensing the received kernels of un-popped corn into the popping chamber;
a driver coupled to the dispenser and including means for moving the dispenser between the receiving position and the dispensing position;
a counter having a plurality of contact surfaces arranged in a sequence; and
a follower coupled to the counter and including means to move the counter incrementally between a first stop and a second stop;
wherein when the dispenser moves between the dispensing position and the receiving position, the driver includes means to position the follower to engage one of the contact surfaces in the sequence and move the counter to a first position between the first stop and the second stop, and when the dispenser again moves between the dispensing position and the receiving position, the driver includes means to position the follower to engage another one of the contact surfaces in the sequence that follows the one of the contact surfaces in the sequence and move the counter to a second position between the first stop and the second stop.
2. The popper of claim 1 wherein the driver pivots via a shaft.
3. The popper of claim 2 wherein the shaft is operatively connected to a lever.
4. The popper of claim 1 wherein the driver is urged to move the dispenser toward the receiving position.
5. The popper of claim 1 wherein the contact surfaces of the counter comprise a plurality of teeth.
6. The popper of claim 1 , further comprising a latch engageable with the contact surfaces.
7. The popper of claim 6 , further comprising a switch follower movable between an energizing position in which contacts are closed to connect electrical power to the blower fan, and a de-energizing position in which contacts are opened to disconnect electrical power from the blower fan, the switch follower engaging the latch in the energized position in a manner such that the latch disengages from the counter.
8. The popper of claim 7 wherein the counter is urged toward the first stop.
9. The popper of claim 1 wherein the follower is urged away from the counter.
10. The popper of claim 1 wherein the counter includes a spur configured to engage the first and second stop.
11. A hot air popcorn popper comprising:
a heating element and a blower fan,
a cooking surface adapted to receive kernels of corn,
a popping chamber into which popcorn enters after being popped, the popping chamber having an inlet and an outlet, the popping chamber inlet being adjacent to the cooking surface, the popping chamber outlet being spaced from the popping chamber inlet;
a seed storage compartment configured to receive kernels of un-popped corn;
a dispenser being configured to move between a receiving position and a dispensing position, in the receiving position, the dispenser receiving kernels of un-popped corn from the seed storage compartment, and in the dispensing position, the dispenser dispensing the received kernels of un-popped corn onto the cooking surface;
a driver coupled to the dispenser and including means for moving the dispenser between the receiving position and the dispensing position;
a follower that moves with the driver as the driver moves the dispenser between the dispensing position and the receiving position;
a counter having a plurality of contact surfaces arranged in a sequence; and
a latch configured to engage the counter and maintain the counter in one of a first position and a second position as the counter is incrementally moved between a first stop and a second stop;
wherein when the dispenser moves between the dispensing position and the receiving position, the driver includes means to position the follower to engage one of the contact surfaces in the sequence and move the counter to the first position between the first and second stops with the latch engaging the counter to retain the counter in the first position, and when the dispenser again moves between the dispensing position and the receiving position, the driver includes means to position the follower to engage another one of the contact surfaces in the sequence that follows the one of the contact surfaces in the sequence and move the counter to the second position between the first and second stops with the latch engaging the counter to retain the counter in the second position.
12. The popper of claim 11 wherein the dispenser comprises a gear rack.
13. The popper of claim 12 wherein the driver comprised a gear.
14. The popper of claim 11 wherein the driver is urged to move the dispenser toward the receiving position.
15. The popper of claim 11 wherein the contact surfaces of the counter comprise a plurality of teeth.
16. The popper of claim 11 wherein the counter includes a spur configured to engage the first and second stop.
17. The popper of claim 11 wherein the follower is urged away from the counter.
18. The popper of claim 11 , wherein the counter is urged toward the first stop.
19. The popper of claim 18 , wherein the latch is di sengageable from the counter to allow the counter to move to the first stop.
20. The popper of claim 19 , further comprising a switch follower movable between an energizing position in which contacts are closed to connect electrical power to the blower fan, and a de-energizing position in which contacts are opened to disconnect electrical power from the blower fan, the switch follower engaging the latch in the energized position in a manner such that the latch disengages from the counter.
