Problems solved by technology

As a result, the ceiling surface can be contaminated due to dirty air being drawn into the room and blown towards the ceiling surface
[0010] (c) In addition, in order to control the airflow from the end of the longitudinal direction of the outlet, the length of the deflection guide in the longitudinal direction of the outlet exceeds the required length, and the ventilation resistance of the air passage increases. As a result, the The load torque of the fan increases, resulting in an increase in the power consumption of the motor

Abstract

Body air outlets 10d of an air-conditioning-apparatus indoor unit 100 each has a substantially trapezoidal shape in plan view and are each defined by a body-air-outlet outer side wall 10d2, a body-air-outlet inner side wall 10d4, and a pair of body-air-outlet end walls 10d1. The body-air-outlet outer side wall 10d2 is provided with a deflection guide 2 at each of long-side ends thereof. The body-air-outlet end walls 10d1 are each provided with a sloping guide 3. The deflection guide 2 has a deflection-guide upper surface 2a that gradually projects toward the body-air-outlet inner side wall 10d4 in a direction toward a body open face 10e (toward a downstream side) and in a direction toward the central part of the body air outlet 10d. The sloping guide 3 has a sloping-guide upper surface 3a that gradually projects toward the central part of the body air outlet 10d as the sloping guide 3 extends closer to the body open face 10e (toward the downstream side).

Description

technical field [0001] The present invention relates to an indoor unit of an air conditioner, and more particularly, to an indoor unit of an air conditioner including an air inlet arranged in a central portion and an air outlet arranged to surround the air inlet. Background technique [0002] An indoor unit of a conventional ceiling-embedded air conditioner has a box with a square cross-section embedded in the ceiling, a fan and an air inlet located in the center of the box, and a heat exchanger arranged around the fan. Therefore, the indoor air drawn substantially upward by the fan forms a substantially horizontal wind flow toward the surroundings in the fan, passes through the heat exchanger, changes direction downward, and is discharged into the room from the air outlet. [0003] At this time, although the airflow is guided by the inner surface of the frame to change the direction, the direction of the airflow cannot be changed reliably due to the inertia of the airflow. ...
