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, efforts have been made to install air conditioners by making effective use of indoor space, but the walls, especially in children's rooms, are already fully utilized, and the remaining usable space is often near the ceiling.

Therefore, it has been proposed to develop products with high heat exchange efficiency that are flat and thin so that they can be installed in spaces near the ceiling.

This idea was made in consideration of these points,
The objective is to provide a product that is thin and highly efficient.

This invention will be described in detail below with reference to the embodiments shown in FIGS. 1 to 3. Reference numeral 1 denotes an indoor casing of a separate air conditioner, which is composed of an upper panel 2 and a lower panel 3.

Reference numeral 4 denotes a fan casing provided in the housing 1, which has suction ports 5 on both side surfaces of the same plane, and partitions the front side into an air outlet 6, and is arranged in the upper panel 2 so as to form an air passage 7. It is fixed to the inside with a fastener 8 such as a screw.

Reference numeral 9 denotes a multi-blade fan, which is thin in the axial direction, is disposed on the outlet 6 side of the air passage 7, and is pivotally supported by a fan motor 10 mounted inside the upper panel 2.

Reference numeral 11 denotes a substantially U-shaped heat exchanger, which is disposed opposite to the suction port 5 side in the air passage 7.

Reference numeral 12 denotes a dew pan, which is located below the heat exchanger 11 and extends from the foamed resin material.

Reference numeral 13 denotes an air guide wall, which is made of a foamed resin material and is slanted so as to closely contact the circumferential side of the fan casing 4 to guide smooth air into the casing 4, and is integrally formed with the dew pan 12.

In the air conditioner configured as described above, the air flow entering from the both side suction ports 5 of the housing 1 becomes a heat exchange air flow when passing through the heat exchanger 11 and flows over the air guide wall 13 in the air path 7. The air is concentrated into the fan casing 4, passes through the multi-blade fan 9, and is discharged out of the housing 1 from the air outlet 6 on the front surface.

This idea is constructed as described above, and the casing formed by the upper panel and the lower panel is divided by a fan casing to form an air path from the inlet to the outlet. A multi-blade fan is installed on the outlet side and a U-shaped heat exchanger is installed on the suction side, and the air guide wall that is in close contact with the circumferential side of the fan casing is integrated with the condensation pan, making the case thinner. It has great practical effects, such as smoothing the heat exchange air flow in the fan casing, guiding a uniform air volume into the fan casing, and providing a product with high heat exchange efficiency.
