Abstract

A popcorn popping unit comprises a blower unit and a popping vessel. The popping vessel has first and second parts assemblable with one another to form the popping vessel. The first part is operatively mounted on the blower unit and the second part has an opening configured to vent pressurized air generated by the blower during cooking operations from the popping vessel through the opening. The popping vessel has at least a portion with inner and outer walls spaced apart from one another to form a double wall construction for the at least portion of the popping vessel. The inner wall may comprise glass and the outer wall may comprise plastic. The inner and outer walls may be transparent.

Claims (9)

1. A popcorn popping unit comprising a blower unit and a popping vessel, the popping vessel having first and second parts assemblable with one another to form the popping vessel, the first part having a proximal end being operatively mounted on the blower unit and a distal end spaced from the proximal end, the second part being removably connected with the first part distal end at a transition, the second part having an opening spaced from the transition, the opening being configured to vent pressurized air generated by the blower during cooking operations and pass popped popcorn kernels received from the popping vessel first part through the opening, the popping vessel first part having inner and outer walls spaced apart from one another to form a double wall construction for the first part of the popping vessel, the popping vessel first part double wall construction defining concentric sleeves with a center axis and the popping vessel second part being arranged perpendicular to the popping vessel first part sleeves center axis with the transition being arranged in a plane at an acute angle to both the popping vessel first and second parts, the second part opening being arranged in a plane perpendicular to the popping vessel first part sleeves center axis and laterally offset therefrom, the popping vessel first part extending outward from the blower unit a distance sufficient to allow the popped popcorn kernels to be visible therein and to accumulate therein to the transition point before the popped popcorn kernels pass to the popping vessel second part.

2. The popcorn unit of claim 1 wherein the popping vessel second part comprises a hood.

3. The popcorn unit of claim 1 wherein the popping vessel first part proximal end is fixedly mounted to the blower unit and its distal end is removably connectable to the second part.

4. The popcorn unit of claim 3 wherein the first and second parts are removably assemblable with one another in such a manner as to allow a user access to an interior of the popping chamber from the distal end of the first part.

5. The popcorn unit of claim 1 wherein the inner wall of the double wall construction is glass.

6. A popcorn popping unit comprising a blower unit and a popping vessel, the popping vessel having first and second parts, the first part being operatively connected to the blower unit, the second part being removably assemblable with the first part at a transition to form the popping vessel, the blower unit having a heating element and a blower fan, the blower unit being adapted to direct heated air into an interior of the popping vessel first part to pop kernels of corn and move the popped kernels of corn from the popping vessel first part toward the popping vessel second part and out through an opening formed in the second part of the popping vessel, the popping vessel first part having an insulated, double wall construction comprising an outer wall outwardly spaced from an inner wall, the popping vessel first part double wall construction defining concentric sleeves with a center axis and the popping vessel second part being arranged perpendicular to the popping vessel first part sleeves center axis with the transition being arranged in a plane at an acute angle to both the popping vessel first and second parts, the second part opening being arranged in a plane perpendicular to the popping vessel first part sleeves center axis and laterally offset therefrom, the popping vessel first part extending outward from the blower unit a distance sufficient to allow the popped popcorn kernels to be visible therein and to accumulate therein to the transition point before the popped popcorn kernels pass to the popping vessel second part.

7. The popcorn unit of claim 6 wherein the inner wall of the insulated double wall construction is glass.

8. The popcorn unit of claim 6 wherein the first part proximal end is fixedly mounted to the blower unit and its distal end is removably connectable to the second part at the transition.

9. The popcorn unit of claim 8 wherein the first and second parts are removably assemblable with one another in such a manner as to allow a user access to an interior of the popping chamber from the distal end of the first part.
