, 5 and the terminal end 15 of the resistor 5, respectively, and change the rotational speed of the motor to switch the blowing force to strong, medium, or weak. , 8.9, 1
0 is a switch that short-circuits the resistor 3 during cooling.

のである。The present invention is characterized in that temperature fuses 11 and 12 are interposed between the resistor 3 and the branch point 13 and between the resistor 4 and the branch point 14 in the circuit configured as described above. ,
If an abnormal current flows due to a fan or motor failure and resistor 3 or 4 becomes high temperature, fuse 11 or 12 will melt and cut off the current, causing the resistor to become red hot and burn out the resin housing of the air conditioner or cause a fire. This is to prevent this from happening.
この場合でもスイッチ１０を閉じれば、モータ２を高速
回転させることができる。Even in this case, if the switch 10 is closed, the motor 2 can be rotated at high speed.
モータ自体が回転できない状況のときは、図示しない主
電流フユーズが溶断して安全が保たれる。When the motor itself cannot rotate, a main current fuse (not shown) blows out to maintain safety.

する効果が大きい。The device of this invention works as described above and prevents excessive current from flowing through the resistor for DC motor transmission in the event of a failure and overheating the resistor. It is possible to prevent burnout accidents of the air conditioner, and the position of the resistor on the air conditioner housing can be determined more freely than before, which has a great effect in making the design and manufacture of the air conditioner easier.
