At this time, the length of the first sliding arm 17 entering the lock groove 20 is such that the electric conduction block 36 is Engaged with the electrical connection groove 12, thereby energizing and moving the air conditioner 11.

When cleaning or repairing the air conditioner internal unit 11, the air conditioner internal unit 11 is pushed to start the drive electric machine 28 in the reverse direction, and the drive electric machine 28 moves the screw rod 27 and rotates it in the reverse direction. When 27 slides the sliding frame 29 and slides upward and the sliding frame 29 and the third sliding groove 26 support each other, the screw rod 27 moves away from the second sliding groove 15, thereby By the action of the top pressure spring and the second top pressure spring 19, the first sliding arm 17 and the second sliding arm 21 return to the initial state, and the screw rod 27 moves the air conditioner internal unit 11 to slide downward. After the screw rod 27 is separated from the screw groove 23, the air conditioner internal unit 11 is taken out from below and cleaned or repaired.

The basic principle, main features and advantages of the present invention have been described and explained above. It should be understood by those skilled in the art that the present invention is not limited to the above-described embodiments, and the above-described embodiments and the description are the principles of the present invention, and do not depart from the significance and principles of the present invention. There are various changes and improvements in the present invention on the premise, and these changes and improvements are within the protection scope of the present invention. The scope of protection of the present invention is defined as equivalent to the attached rights request.
