Rice cooker preset power off timer
Source: InternetPublisher:红水杯 Keywords: CD4060 timing circuit Updated: 2024/06/14
As shown in the figure, this is the preset power-off timing circuit for the rice cooker. The timing range of this timing circuit can be from 1 hour to 12 hours, and can be adjusted by PR. The timing mode is counting type, and the control mode is preset power-off timing. BT33 is used in the circuit to generate the trigger signal of the thyristor VS. If BT33 stops oscillating, VS is turned off and CZ is powered off.
