WALL-MOUNTED AIR-CONDITIONING APPARATUS

摘要

An upper suction port is formed in a main-body upper part of an air-conditioning apparatus main body, a suction opening part is formed in a front grill disposed on a main-body front face of the air-conditioning apparatus, a suction opening whose opening is directed upward is formed by consecutively providing an air guide wall inclined downward inside the main body on the upper edge of the suction opening, and the suction opening is located between a part, in the main-body height direction, lower than a straight line passing through a rotation center of an impeller and a closest contact point between the impeller and a front-face heat exchanger and a part, in the main-body height direction, higher than a straight line parallel with the straight line and passing through the impeller and a tongue part of a stabilizer.

主权项

1. A wall-mounted air-conditioning apparatus comprising:
an air-conditioning apparatus main body; a front-face heat exchanger arranged on the main-body front-face side of the air-conditioning apparatus main body and a heat exchanger arranged on the main-body back face side; a cross flow fan which has an impeller disposed inside the main body of the air-conditioning apparatus main body, a stabilizer which separates the inside of the main body into an impeller suction region and an impeller blow-out region, and an arc-shaped guide wall disposed on the impeller blow-out region side, sucks air from the impeller suction region and blows out the sucked air into the impeller blow-out region; and a front grill disposed on the main-body front face, wherein an upper suction port is formed in the upper part of the main body of the air-conditioning apparatus main body; a suction opening is formed in the front grill, and an air guide wall inclined downward is provided consecutively inside the main body on the upper edge of the suction opening, to define a suction opening part between respective bottom edges of the air guide wall and the suction opening, the suction opening part producing airflow therein substantially in a direction from an upper part to a lower part of the suction opening part; and the suction opening part is located between
a part lower in the main-body height direction than a straight line A passing through a rotation center of the impeller and the closest contact point between the impeller and the front-face heat exchanger anda part higher in the main-body height direction than a straight line B, the straight line B being in parallel with the straight line A and passing through the impeller and a tongue part of the stabilizer.
