1) Program control
As the control center of the appliance, the program controller directs the appliance to meet the
demand of the user like the brain of human body. This part has acquired the UL certification, with long
operation life and reliable performance.
2) Temperature sensor
The temperature sensor of this appliance has also acquired the UL certification. It acts as nerve
center during usage of the appliance. It is used to detect the dry degree or temperature, and can effectively
prevent the defects like the crimple of laundries owing to overheating.
3) Power transmission system
During drying, Motor 1 transmits the driving power to Tumbler 5 through Belt 2 and
Multi-wedge belt 3. Then Tensioning wheel 4 tensions the belt under the action of
tensioning spring. At the same time, it also increases the transmission wrap angle of the
pulley, and improves the transmission efficiency of the belt. The motor rotates to one
single direction during drying. The tumbler will also rotate to one single direction. The
motor is centrifugal type, and has acquired the UL certification, with strong driving power
and long operation life.
4) Air intake and exhaust system
The appliance collects air through shutter, and heats the air with electric heating thread. The air
exhaust system composed of volute impellers generates negative atmosphere pressure under the suction
force, and thus attracts the hot air into the tumbler to dry the laundries. The air intake and exhaust system
has high degree of tightness, and improves the thermal efficiency.
5) Heating system
The electric heating thread installed on the heating plate at the rear of the cabinet, is the heating
source of the appliance. The exchanging of cold and hot air is realized by it. The heating power of the
electric heating thread is about 4700W. It can raise the air temperature rapidly, and offer hot air continuously.
