Electrical rice cooker timer

The utility model discloses an electrical rice cooker timer, which is composed of a rectifying and voltage-stabilizing circuit, a reference clock pulse circuit, a subtraction counting circuit, a control circuit, and a power switch of the electrical rice cooker. The rectifying and voltage-stabilizing circuit is respectively connected with the control circuit and the reference clock pulse circuit, the reference clock pulse circuit is firstly connected with the subtraction counting circuit and secondly connected with the control circuit, and the switch is the joint of the relay in the control circuit. When the dial switch in the subtraction counting circuit is preset with a corresponding value, namely, the needed time, the reference clock pulse circuit can send a pulse signal to the subtraction counting circuit, and after the value is zero, the control circuit is conducted by the pulse signal; thus, the relay is powered on, and the power switch of the electrical rice cooker is closed. The utility model has reliable performance, correct timing, and visual and convenient use.
