1 自制电热毯温度控制器 自制电热毯,如果只用开关控制,则不能实现调温,使用时既不方便也不利于节能.若使用一个二极管和一个床头开关,可根据环境温度和各人的习惯,很方便地进行温度控制.如图1所示,二极管V的型号为IN4007,其原理为:当开关处在“通”的位置时,二极管不导通,电热丝得到全电压,此时发热量最大;当开关处在“断”的位 1 Homemade blanket temperature controller Homemade blankets, if only the switch control, you can not achieve temperature control, use is neither convenient nor conducive to energy saving.If you use a diode and a bedside switch, according to the ambient temperature and each person Of the habit, it is easy to carry out temperature control.As shown in Figure 1, the diode V model IN4007, the principle is: When the switch is in the “pass” position, the diode does not conduct, the heating wire to get the full voltage, this When the heat is the largest; when the switch is in the “off” position
