Description

[Detailed Description of the Invention] This invention relates to a separate air conditioner, and particularly to a flat indoor unit installed near the ceiling.

In recent years, attempts have been made to install air conditioners by making effective use of indoor space, but most of the walls, especially in rooms used by students, are used, leaving space near the ceiling. In order to effectively utilize this space, thin and flat air conditioners have been proposed.

The purpose of this invention is to satisfy these demands, achieve a thinner design, and obtain smooth air flow and efficient air volume.

This invention will be explained below with reference to the embodiments shown in FIGS. 1 to 3.

Reference numeral 1 denotes an indoor/outdoor casing of a separate air conditioner, which is composed of an upper panel 2 and a lower panel 3.

Reference numeral 4 denotes a casing provided within the housing 1, which is partitioned into an air passage 7 by partitioning an inlet 5 on both sides of the same plane and an outlet 6 on the front.

8 is a heat exchanger, which is arranged in a substantially U-shape corresponding to the suction port 5 side of the air passage 7.

Reference numeral 9 denotes a blower device, and the housing 1 consists of a motor 10 fixed to the central upper panel 2 side and a flat multi-blade fan 11.

Reference numeral 12 denotes a rectifying rib provided on the inside of the upper panel 2 of the casing 1, which directs the airflow flowing through the air passage 7 leading from the wide inlet 5 to the air outlet 6 through the bell mouth portion 13 of the casing 4 to the central blower. 9 to flow smoothly and quantitatively.

Reference numeral 14 denotes a rectifying projection provided on the front surface of the upper panel 2 of the housing 1, which is integrally molded inward toward the motor 10 at approximately the center of the reinforcing and rectifying band 15 on the front surface of the upper panel 2.

In the air conditioner configured in this manner, the intake airflow passes through the air passage 7 formed by the rectifying ribs 12, passes through the bell mouth portion 13, passes through the multi-blade fan 11, and reaches the front air outlet 6.
However, at this time, in the front part of the air passage 7 on the side of the suction port 5, there is a reinforcing and rectifying band 15.
The airflow flows from both sides and collides with the rectifying protrusion 14 at the center of the front surface, thereby flowing to the bell mouth portion 13 of the casing 4 without merging, forming a smooth flow path from the inside of the casing 4 to the front air outlet 6.

As mentioned above, this idea is constructed by creating a side suction inside a flat housing, forming an air path with the same plane front blowout using the casing, and installing a heat exchanger and a blower device in the air path. Since a rectifying protrusion is provided in the center of the front of the upper panel on the suction side, it is possible to form a thin and flat housing, prevent the front of the upper panel from sagging, and prevent wind It has great practical effects, such as creating a smooth flow path without causing collisions of flowing air at the front part of the path, and being able to obtain an efficient air volume.
