Joyoung soymilk machine circuit

ff heat begins, MCU @Jiaojie comes out with poison rg flat, V=I'4. The conductor is connected, the relay K2 absorbs and flows 220V power, the terminal breaker FU,
  I<i normal wide contact, KZ normally open contact,. K§Normally closed contact reaches the electric heating point EH, which pre-releases the water in the cup. There is a negative temperature coefficient thermistor RT in the temperature transmitter J.
  It and Rr form a partial voltage circuit to divide the voltage V (Ⅵ℃). The partial voltage is added to the Mcu② pin through the P.
  The water temperature rises, the RT resistance drops, and the MCU ② pin level goes up. When the water temperature reaches the set value (generally around 80°C), the MCO
  instructs the MC@ pin to output a low level according to the high level detected by the ⑦ pin, and K2 is released to terminate preheating. Preheating takes about 88n.
    2) Beating: After preheating, the @ pin of 'Mcu outputs high level. VTl conducts, Kl warms up, AC voltage K1 opens the contact,
  and is added to the beating motor M to drive the blade to beat at high speed. Beat beans for about s each time, with an interval of 15 seconds, and beat a total of 1 times.
