PURPOSE:To simplify switch construction of the captioned air conditioner having both manual and automatic mode selections by connecting interlock switches of an automatic temperature controller in parallel with mode selection manual switches so that moving contacts of the said automatic temperature controller correspond to fixed contacts of a position sensing switch. CONSTITUTION:When any mode is selected with manual switches 15-18, moving contacts 21 and 22 come in contact with fixed contacts 23-32 according to the respective mode selected and a direct-current motor 1 is turned in a specified direction through induction of either the first relay switch 12 or the second relay switch 13. Following the above-mentioned sequence, a rotary damper (not shown in the drawing) turns to a specified position and is stopped with a position sensing switch 20. An interlock switch 33 interlocking with an air mixing flap, in place of the manual switches 15-18 of the position sensing switch 20, can drive the rotary damper through a switch 19, a moving contact 34, and fixed switches 35-37. With the above arrangement the construction of the switches can be simplified. |
