through slots in the forward end of the housing 35, and
the heated air is introduced into the interior of the tank

back of the tank and connects with the interior of the
washing chamber through an inlet passage 41.
The successive steps in the washing and drying cycle
are controlled by a sequence timer indicated generally at

with a dial 45. The arrangement in this respect and the
sequence of operation may be as disclosed in Geiger et
