electronic watch circuit

For children who are homeschooled, getting up on time in the morning and going to school in time are very
important family chores. If you can make a digital watch timer, that would be a very good thing.
  It can control the electric rice cooker to heat rice. After a period of use, it has stable performance and accurate timing.
In addition, it can also turn on or off some home appliances at scheduled times. It is introduced as follows for readers to review.
    The circuit is shown in Figure 1-52. Choose an electronic watch with an alarm timer function. Disassemble the electronic watch, remove the speaker
inside , and connect the two wires originally connected to the speaker to the second main T2 of the thyristor VTH and the door panel G.     When the relay coil K is energized and the normally open contact connected to the AC 220V is connected, the rice cooker can heat and cook. When the timer expires, it will automatically shut down.
