九阳豆浆机原理电路图

九阳豆浆机原理电路图 整机电路由电源电路和集成电路IC1(时基电路NE555)、IC2(带振荡器的14级串行二进制计数/计分频器MC14060BCP)、IC3(三输入或非门电路CD4025BE)与外围元件组成的温控触发电路、分频计时电路、控制执行电路组成。通过继电器K1、K2控制“打浆”电机M、加热器L及报警电路。 插上电源插头AC220V市电经变压器降压输出20.5V交流电压，由二极管D1~D4整流、C2滤波后得到24V直流电压，为继电器K1、K2的线圈供电，此直流电压再经R15降压限流、C3滤波、D7稳压后为IC1、IC2、IC3及报警电路供电。 IC1、感温探头PTC及IC3中的第一个3输入或非门等元器件组成IC2计时复位电路和打浆电机控制电路。由于感温探头PTC中的热敏电阻的阻值呈正温系数，在接通电源的瞬间，其阻值很小，使IC13脚输出正脉冲，IC2被触发复位，计时开始。随PTC阻值增大，IC13脚输出低电平，使IC33脚(1a)也处于低电平，又因IC3 13脚与温控探头PTC外壳相连，通过豆浆液与地接通，这就使IC3 3脚不能通过K13呈高位。再则，IC34脚(1b)、5脚(1c)分别与IC22脚(IC2的Q13)、1脚(IC2的12级分频端Q12)相连，计时未完时此两脚也呈低电平，使IC36脚输出高电平，T3导通，继电器K2得电，K2-1接通，打浆电机工作。此时IC3 6脚输出的高电位又通过D10使得IC311脚、(3a)也呈高电位，IC3 10脚输出低电平，T4不导通，加热器L不能对豆浆加热。 这样，只要豆浆中有豆浆，IC3 13始终处于低电们，使打浆电机工作，否则打浆电机就不能被触发而工作，起到自锁作用。而打浆电机工作时，豆浆加热器就不加热，实现分时控制。 当IC2控制的打浆计时器到达设定的时间后，IC2 13脚(Q9)输出高电平，使IC3 8脚也呈高电位，6脚呈低电位，使得T3截止，打浆电机失电而停转，同时使得11脚(3a)回到their own conditions to develop the correct road, the maximum to avoid investment risk, gain profit.(three) vigorously promote the brand.
