JPH10274432A - Wind direction changing unit for blow-out port - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a wind direction changing unit for blowout port in which the vertical blow-out range can be set arbitrarily depending on the installation conditions of an air-conditioner, or the like, and the setting of blow-out range can be changed easily by constructing a bearing part for regulating the movable range of a deflector such that it can be removed and rearranged through rotary motion. SOLUTION: A protrusion 2b formed at the shaft part 2a of a deflector 2 moves in a protrusion receiving groove 5b of a bearing part 5 fixed to a containing box 4 when the deflector 2 is rotary driven and abuts against the circumferential end of the protrusion receiving groove 5b thus regulating the movable range of the deflector 2. The deflector 2 (protrusion 2b) operates with reference to the end part of the protrusion receiving groove 5b within a range determined by the number of signals delivered from a control board. A plurality of key grooves 4d are made in the recess 4c of the containing box 4 and the position of the protrusion receiving groove 5b (movable range of the deflector 2) can be changed by removing and rotary moving the bearing part 5 and rearranging in another key groove 4d.
