BACKGROUND AND SUMMARY
This disclosure relates to hot air popcorn poppers. The popcorn popper may be configured to provide a single serving size of popcorn. The popcorn popper may also be configured to provide multiple servings. The popper unit has a cooking portion into which kernels are placed. Hot air is directed into the cooking portion to pop the kernels. The cooking portion may comprise the blower unit, a popping vessel or a carafe. The popped kernels expand upwards and fill the popping vessel or the carafe. The popping vessel or the carafe may have a vent at its top end to allow the hot air used for cooking the kernels to escape from the popping chamber or carafe. The vent may be formed in a lid that otherwise seals the top open end of the carafe. The vent may discharge to another serving dispenser.
In one aspect, once popping is complete, the carafe may be used as a serving container. In a variation of this aspect, the vent at the top of the carafe may be sealed and popper unit may be inverted with the carafe attached to the popper unit so the popped kernels fill the carafe. The carafe may then be removed from the popper unit in the inverted position. The carafe then serves a serving bowl or dispenser and the user may mix seasonings in the carafe. In another variation of this aspect, the carafe may be removed from the popper unit. The bottom of the carafe may have a fine mesh screen, cooking grate or other cooking surface which holds the popped kernels. The carafe may be transferred to a stand-like pedestal to seal the bottom of the carafe. The lid and or vent on the carafe top end may be fully opened to allow use of the carafe as a serving bowl or dispenser from the carafe top, and the user may mix seasonings in the carafe.
In another aspect, a hood may be detachably connected to the carafe and popped kernels may be directed out of the hood to a separate serving dispenser. In another aspect, the popping chamber may comprise first and second parts removably assemblable with one another to form the popping chamber.

DETAILED DESCRIPTION
FIG. 1 shows a cross-sectional view of one embodiment of the popping unit 20. The popping unit 20 comprises a carafe 22 and a blower unit 24. The carafe 22 has an open bottom 26 which detachably connects to the blower unit 24. Opposite the open bottom 26 is a top 28 which is generally sealable with a lid 30. The lid 30 may be removably attachable to the carafe 22. The lid 30 may have a hinged or flip style vent or opening 32 to allow hot air from the blower unit to pass through the carafe during popping operations. As shown in the drawings, the flip vent 32 may be pivotally connected and snapped to the lid. The lid 30 may be removable from the carafe to allow cleaning. While a flip top vent is shown, other types of vents may be formed in the lid, including a louvered opening, an iris opening, or perforations (FIGS. 11-14). The open bottom 26 of the carafe may be internally threaded 34 or have other removably attachable connections to allow the carafe to be removably attached to the blower unit.
The blower unit 24 may comprise a housing 40 with a hollow interior 42. In the hollow interior 42 of the housing is a blower fan 44 and a heating element 46. Ambient air may be drawn into the hollow interior 42 through openings 48 in the housing exterior through action of the blower fan 44 and pass over the heating element 46. The blower fan 44 and/or heating element may be battery powered or powered from an external AC or DC power source with a power cord 50. The blower fan and/or heating element may be deenergized with a switch (not shown) located on the housing or the power cord. The switch may be manual or operate via a timer. A plenum 52 may direct the heated air to the upper part of the housing after passing over the heating element 46. The upper part of the housing may have a cooking surface or grate 54 upon which unpopped kernels 60 are placed. The hot air may exit the plenum and circulate around the cooking surface, heating the kernels, and enabling the kernels to pop. Once the kernels pop, they may expand upward into the carafe through the carafe open bottom 26. The heated air may flow through vents 62 in the upper part of the housing into the carafe after circulating around the cooking surface or grate. The pressurized, heated air may push the popped kernels away from the cooking surface or grate 54 into the carafe thereby allowing the unpopped kernels to cook and expand. Hot air may pass out through the flip vent 32 on the lid 30 during cooking operations.
FIG. 2 shows a step in a method of using the popping unit 20. In FIG. 2, popping operations are occurring. In FIG. 2, the flip vent 32 is open and air is drawn in through the openings 48 of the housing of the blower unit 24 by the blower fan to be heated by the heating element. The heated air circulates around the cooking surface or grate 52, heating the kernels and allowing them to pop into the carafe 22. The heated air may flow from the housing of the blower unit 24 into the carafe 22 and out through the flip vent 32.
FIG. 3 shows another step in a method of using the popping unit after cooking operations are complete. Once operations are complete, the flip vent 32 top may be moved from the open position to the closed position. When popping is complete, the blower motor and heater may be de-energized. De-energization of the blower and heating element may occur via a timer or may be performed manually by the user with a switch after determining that all of the kernels have popped.
FIG. 4 shows another step in a method of using the popping unit in an inverted position. FIG. 5 shows another step in a method of using popping unit where the blower unit 24 being disconnected from the carafe 22, and use of the carafe as a serving dispenser. An optional secondary lid 64 may be placed on the open bottom end 26 to allow transportation of the carafe by the user. The secondary lid 64 may also allow the user to maintain the temperature of the popped corn longer and allow mixing of seasonings by shaking the carafe with the top and bottom lids installed. Seasonings and butter may be placed in the serving dispenser as desired through the open bottom of the carafe. With the flip vent 32 closed, the lid 30 at the carafe top forms a seal to contain the popcorn and seasonings. The secondary lid 64 and top lid 30 may form closures that are sufficient to allow normal movement of the carafe during use by the user without contents of the carafe leaking from the carafe. The closures may be sufficient to contain liquids inside the carafe. Thus, the carafe may be used on-the-go or as a travel mug with popcorn. A handle 66 may be provided. The secondary lid 64 may have an access hole (not shown) to allow the user to consume the contents of the carafe with the secondary lid installed.
