Description

Air conditioner and frame assembly {AIR CONDITIONER AND FRAME ASSEMBLY}

The present disclosure relates to air conditioners and frame assemblies, and more specifically, to air conditioners installed in windows.

An air conditioner is a device that exchanges heat with sucked indoor air and supplies the heat-exchanged air indoors.

In the case of an air conditioner installed on a window, it is fixed to the window so that one side of the case faces the indoor space and the other side of the case faces the outdoor space.

In order to fix the case of the air conditioner to the window, a separate frame may be provided between the window and the case.

The frame is provided so that its upper and lower lengths can be varied according to the height of the window, allowing the air conditioner to be installed on the window regardless of the window height.

However, the conventional frame had a problem in that it was not easy to fix the frame to the window frame after changing the upper and lower lengths. Patent Document 0001 and Patent Document 0002 disclose a frame for installing an air conditioner on a window, but it is difficult to fix a frame with a variable length to the upper and lower parts of the window frame, and a holding structure to maintain the variable length is required. Due to its absence, there was a problem that the bond between the frame and the window frame was weakened.

In addition, the conventional frame requires a number of separate fastening members such as bolts and nuts to fix the frame of variable length to the window frame, which increases the amount of accessories for fixation and increases the work time for frame installation. There was.
