ABSTRACT:
A smoking appliance utilizes a solid-phase cooling medium for tempering and treating smoke. The appliance has a housing which defines an upstanding cooling chamber. A burning bowl is arranged to introduce smoke to be treated into a lower portion of the cooling chamber. A flexible hose communicates a mouthpiece with the chamber for withdrawing treated smoke from an upper portion of the cooling chamber. A removable container is provided for supporting a solid-phase cooling medium within an intermediate portion of the cooling chamber. The cooling medium defines a plurality of flow paths for transmitting smoke from the lower portion to the upper portion. During its travel through the cooling medium, the smoke is exposed to a large surface area of the cooling medium to effect a thorough tempering and treating action. While the solid-phase cooling medium preferably takes the form of a reusable frozen cartridge, it may also constitute a plurality of pieces of ice supported within the container. A drainable residue collection area is provided at the base of the cooling chamber for catching ash particles and residue-containing liquid. A perforated wall is provided in the bottom of the container to restrain ash particles from coming into contact with the solid-phase cooling medium while, at the same time, permitting smoke to filter gently upwardly through the cooling medium.
