DRYING TUMBLER WITH TEMPERATURE LIMITING AIR FLOW BYPASS

摘要

A drying tumbler is provided which includes a temperature bypass which helps prevent an excessive amount of heat from building up in the tumbler. The drying tumbler includes a rotatable drying chamber for containing items during drying. The drying tumber further includes an air handling system that has a heat source which is operable to provide heated air into the interior space of the drying chamber through an air handling and a blower operable to draw air from the interior space of the drying chamber through an air handling outlet. The air handling system is operable so as to produce an air flow through the drying chamber which is substantially parallel to the rotational axis of the drying chamber. A bypass passageway is provided which communicates with the interior of the drying chamber through a bypass inlet which is in spaced relation from the air handling outlet opening and the blower. The bypass passageway defines an air flow bypass path from the interior space of the drying chamber to the blower which bypasses the air handling outlet opening.
