Description

[Detailed Description of the Invention] The present invention relates to an air diffusion device for an air conditioner that reliably diffuses and supplies heat-exchanged air to every corner of a room with a small amount of electric power.

Normally, a ceiling-hung air conditioner has an intake and an outlet at the bottom of the machine, and a heat exchange coil and a blower are placed inside. However, since most of these systems simply discharge air vertically downward from the air outlet exposed on the lower surface of the indoor ceiling, air exchange is always carried out at a certain point in the room. Therefore, it is not only difficult to cool and heat the entire room almost evenly, but also requires frequent efforts such as having to change the opening direction of the air outlet to the desired direction each time. That's what I was doing.

In view of the above-mentioned drawbacks, the present invention involves improving a part of the heat exchange coil to ensure that the spirally diffused air is discharged into the room from the outlet, thereby completely exchanging heat to each corner of the room. In an air conditioner intended to supply air, in which an electric motor, a blower, and a heat exchange coil are arranged in an external casing, and a lower suction port and a blowout port are respectively provided, the heat exchange coil It is an object of the present invention to provide an air diffusion device for an air conditioner, characterized in that an inner piece and an outer piece of a heat radiating plate A forming a heat dissipation plate A are bent in opposite directions according to the blowing direction of the blower.

Hereinafter, embodiments of the present invention will be described in detail with reference to illustrative drawings. 1 is a round cylindrical outer casing, in which an electric motor 2 and a horizontal blower 3 are disposed in the center thereof, and the outer periphery of the blower 3 is An annular heat exchange coil 4 is disposed at.

In the annular heat exchange coil 4, as shown in FIGS. 2 and 3, the outer and inner pieces of each heat sink A are appropriately bent in different directions according to the blowing direction of the blower 3.
A' and A'' are formed and arranged on the heat dissipation tube B at regular intervals.

Further, an internal casing 5 is disposed and fixed below the annular heat exchange coil 4, and a suction port 6 and a suction port support frame 7 are connected to each other below the annular heat exchange coil 4 so as to be movable vertically and retractably.

The air outlet 8 communicates with an air guide path 9 formed between the outer casing 1 and the inner casing 5, and is opened at the outer periphery of the suction port 6.

In the figure, numeral 10 is a drain pan, 11 is an air filter, C is a bend, C' is a water inlet,
C″ is the water outlet.

The air diffusion device for an air conditioner according to the present invention has the above-mentioned configuration, and the air introduced into the machine from the suction port 6 by the rotation of the blower 3 is heated to an appropriate temperature by the heat exchange coil 4. The coil passes through while being replaced, but when the coil passes through, the heat sink A
Since the outer and inner pieces of the heat exchanger coil 4 are bent in opposite directions, A' and A'' are formed, the passing air flows through the coil and forcibly generates a circular flow effect, which causes the conduction of the outer circumference of the heat exchange coil 4 to occur. The air turns into a swirling airflow in the air passage 9 and is sent into the room through the air outlet 8.

In this way, sufficient heat exchange and distribution can be expected not only to every corner of the room but also to narrow places due to the blowing action of the swirling air flow, which eliminates the conventional constant heat exchange and distribution. The so-called unevenness is completely solved by heating and cooling only the area, and since the bending direction of the heat sink A is formed in the direction of the air blowing by the blower 3, the air when passing through the coil is As shown by the arrow in Figure 3, air passes through the air with the least amount of resistance. Therefore, a large amount of air can be easily obtained with a small amount of electric power, there is little wind noise, the heat dissipation effect is large, and the overall shape of the coil is This air conditioner is ideal for the energy-saving era, as it can be made extremely compact.

In addition, in the present invention, the air circulation state, wind force, etc. can be easily adjusted by adjusting the angle, length, interval, etc. of the bends A' and A'' of the heat sink A. Needless to say, better effects can be expected by providing spiral guide pieces, grooves, etc. on the inner surface of the outer casing 1 or the outer surface of the inner casing 5.
