Claims

[Scope of utility model registration request]

A set shaft that is supported by a timer board and has a slow gear and is slidable in the axial direction, a low-speed gear train that rotates the set shaft at a low speed while meshing with the slow gear, and a set shaft that is fixed to the set shaft A rice cooking start cam that allows the set shaft to move in the axial direction by cooperating with a cam groove provided on the timer board at a predetermined rotational position, and a main rice cooking switch that is played with the rice cooking start cam and works in cooperation with the rice cooking start cam. a spring that presses and biases the rice cooking start cam toward the timer board; a uneven and sectional cooking cam that is engaged with a set shaft and has a rapid gear and is movable in the axial direction; A speed gear train that rotates the irregularity and work area cooking cams at high speed in mesh with the rapid gear, an irregularity switch that controls the uneven heater in cooperation with the uneven cam, and an unevenness switch that cooperates with the work area cooking cam. There is a section cooking switch that temporarily controls the main heater during uneven operation, and a switch that drives the low-speed and high-speed gear trains and temporarily stops rotation during cooking, switching from rice cooking to uneven operation. A timer for a rice cooker having a drive motor that restarts rotation at a certain time.
