2. Constructions and Operation
1.
ConstructIons
The kneader blade attached to the inner pot ass’y is rotated by the main motor by way of the pulley and
the belt. The ingredients inside of the inner pot are kneaded by the kneader blade. The inside of the
temperature is controlled by the thermal sensor and the heater between the processes of “kneading”
and “baking” .

●Description of operation
(1)
VDD-VSS Power supply (5V)
The secondary output of power transformer(PT101 ) is given bridge-rectification by the diode
(D101 -D104) and the condenser (C107) to produce 13V voltage at@. The voltage at@is used to
compose@ 5V power supply by the operation of constant voltage circuit consisting of 3-terminal
output voltage regulator (ICI 01).

● Description of operation
(1) Heater control circuit
When the voltage at pin 13 of
the micro computer (ICI) becomes Low (OV), the signal will drive
transistor (QI 05), transistor (Ql 03), Photo triac (PH101 ), and thentriac(TAC101 ) to operate the
heater,
(2) Motor control circuit
When the voltage at pin 14 of the micro computer (IC1) becomes Low (OV), the signal will drive
transistor (Q104), transistor (Ql 02), Photo traiac (PH1 02), and thentriac(TAC102) to operate the
motor.
