PURPOSE:To automatically control optimum temperature in a room and easily and securely mount in a cassette structure time air-amount variable device on an air fan outlet of a duct by integrally incorporating the variable air amount device in a blow-off outlet mechanism. CONSTITUTION:There is constructed a blow-off outlet grill such that a blow-off outlet grill is demountably coupled integrally in a casette structure with a blow-off outlet of a duct, wherein a variable air amount device 3 is disposed inside a blow-off outlet body 1 or in a fan air passage A for adjusting an air amount flowing in the blow-off outlet body 1 and a blow-off outlet panel 4 including many venting holes is mounted on an open surface of the blow-off outlet structure 1 freely to be opened and closed. Further, on part of the blow- off outlet panel 4 there is mounted a receiver part 5 of the variable air amount device communicated and coupled with the variable air amount device 3 and a signal is sent from a wireless remote control switch, etc., through the receiver part 5 to actuate the variable air amount device 3 for automatic control of room temperature. |
