13.有冻结食品室与人工除霜的电冰箱的电路通过图8中接地的延长电线和插头1供电。电路供电给配电板插座2。从配电板插座分出二条线路。一条线路供电给箱体电灯3。它由箱体开关4控制。箱体开关和电灯是串联的。电冰箱门开灯亮、门关灯熄。第二条线路接到电动压缩机。恒温器5和电路串联并控制压缩机6的运转。当箱内温度升到某预定温度,恒温器与电动机接通电路。压缩机转动并进行制冷循环。当箱内温度下降到所要求的最低温度,恒温器即切断电流,电动压缩机就停止运转。这种型式的电冰箱一般还有两个附加的电气装置。其一是个电阻热丝。亦名周边干燥器,由7示出。它装在冻结箱门框上。
13. The circuit of a refrigerator with a frozen food compartment and manual defrosting is powered by the grounded extension cord and plug 1 in Figure 8. Power supply circuit board socket 2. Divide two lines from the switchboard socket. A line power supply to the box light 3. It is controlled by the cabinet switch 4. The cabinet switch and the lamp are in series. Refrigerator door lights bright, door lights turn off. The second line received the electric compressor. The thermostat 5 and the circuit are connected in series and control the operation of the compressor 6. When the temperature in the chamber rises to a predetermined temperature, the thermostat and the motor are switched on. Compressor rotation and refrigeration cycle. When the temperature inside the box drops to the required minimum temperature, the thermostat switches off the current and the electric compressor stops. This type of refrigerator generally has two additional electrical devices. One is a resistance hot wire. Also known as the peripheral dryer, shown by 7. It is mounted on the freeze box door frame.
