Abstract:
1. A ceiling embedded type air conditioner comprising: a casing housing the air conditioner being embedded in a ceiling; an outlet configured to blow out air conditioned air toward an indoor space; a guiding member movably mounted with respect to said casing to change a blow-out vertical direction of the air conditioned air at said outlet; and a control device operatively controlling said guiding member between a plurality of fixed positions tier changing said blow-out vertical direction of the air conditioned air blown out from said outlet to said indoor space, said plurality of fixed positions including at least a first blow-out direction, a second blow-out direction and a third blow-out direction, said control device configured to perform a ceiling airflow clinging prevention control operation in which said control device gives a temporary blow-out direction changing instruction to said guiding member that temporarily changes said blow-out vertical direction of the air conditioned air from said first blow-out direction to said second blow-out direction only after determining said guide member has been in said first blow-out direction for a first predetermined time or longer, said second blow-out direction being a direction corresponding to one of said fixed positions at which said guiding member is more downward than said first blow-out direction, said first blow-out direction being a direction corresponding to an upper limit of said fixed positions at which said guiding member changes said blow-out vertical direction of the air conditioned air blown out from said outlet to said indoor space, said third blow-out direction being a direction corresponding to one of said fixed positions at which said blow-out vertical direction of the air conditioned air from said guiding member is between said first and second blow-out directions, said control device being further configured and arranged to give said temporary blow-out direction changing instruction based only on an amount of time said guide member has been in said first blow-out direction when said ceiling airflow clinging prevention control operation is performed, and said control device giving a blow-out direction user setting instruction to said guiding member to change from said second blow-out direction to said third blow-out direction without changing to said first blow-out direction in response to a user input command after said guiding member has temporarily changed said blow-out vertical direction of the air conditioned air from said first blow-out direction to said second blow-out direction, when said blow-out direction user setting instruction is given during a time when the blow-out vertical direction of the air conditioned air is in a process of being temporarily changed by said temporary blow-out direction changing instruction from said first blow-out direction to said second blow-out direction.
