Detailed ways

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 2 is a sectional view showing the ceiling-mounted air conditioner provided by the present invention. As shown in the figure, the ceiling-mounted air conditioner includes a box-shaped main body casing 10 installed inside a ceiling 100 and a ceiling panel 20 combined with the open lower end of the main body casing 10 and covering the ceiling opening at its peripheral portion.

Inside the main body casing 10 are provided a turbofan 11 which sucks in air from the lower part and discharges it radially, and a drive motor 12 for driving the turbofan 11 . The driving motor 12 is fixed on the upper surface inside the main body casing 10 . In addition, a heat exchanger 13 is provided around the turbofan 11 in a manner surrounding the turbofan 11 for exchanging heat with air discharged from the turbofan 11 . Moreover, a condensed water receiver 14 is provided at the lower part of the heat exchanger 13 for collecting condensed water generated during the heat exchange and discharging. The lower end of the condensate receiver 14 is supported by the upper end of the ceiling panel 20 .

A suction port 21 for sucking indoor air is formed at the center of the ceiling panel 20 , and a plurality of discharge ports 22 are formed outside the suction port 21 . Also, the suction port 21 of the ceiling panel 20 is provided with a filter 23 for filtering air, and the inside of the filter 23 is provided with an air guide plate 24 forming an opening 24a in the center to guide the sucked air to the center of the turbofan 11.

As shown in FIG. 3 , discharge ports 22 of the same shape are formed at four positions around the ceiling panel 20 . Each of the outlets 22 has an elongated shape parallel to the four sides of the ceiling panel 20 and has the same size. As a result, the air discharged from the heat exchanger 13 can be supplied to the room through the surrounding discharge ports 22, thereby smoothing the indoor air circulation. In addition, when the ceiling panel 20 is viewed upward from the lower part of the ceiling panel 20, since the outlets 22 around the periphery are positioned in a balanced position, it is possible to provide a beautiful appearance.

Each discharge port 22 of the ceiling panel 20 is respectively provided with a wind deflector 31 for adjusting the wind direction, and a motor 32 for rotating each deflector 31 is provided at a position adjacent to each discharge port 22 inside the ceiling panel 20 . The air deflector 31 extends along the length direction of the outlet 22 , and its two ends are rotatably supported by the two ends of the outlet 22 . The motor 32 is connected with the shaft at one end of the wind deflector 31 to rotate the wind deflector 31 clockwise or counterclockwise.

Furthermore, a drain pump 34 for draining condensed water, a refrigerant pipe 35 connected to the heat exchanger 13 , and other electrical components (not shown) are provided inside the ceiling panel 20 . However, since the interior space of the ceiling-embedded air conditioner is relatively small, some of these components may be exposed outside through the discharge port 22 . Therefore, in order to prevent these built-in components 34 , 35 from being exposed through the discharge port 22 , a cover member 40 for covering a part of the discharge port 22 is provided at the discharge port 22 adjacent to the built-in components 34 , 35 .

As shown in FIGS. 3 to 5 , the cover member 40 covers a partial area on one side of the discharge port 22 . That is, as shown in FIG. 4 , by covering a part of the discharge port 22 with the cover member 40 , internal components such as the piping 35 are prevented from being exposed to the outside. Such a cover member 40, as shown in FIG. 5, includes a flat plate portion 41 in a partial area of the cover discharge port 22 and a flow guide portion 42 extending a predetermined length from the end of the flat plate portion 41 in the air discharge direction.

The flow guiding portion 42 includes an air deflector entry slot 45 and a first flow guiding portion 43 and a second flow guiding portion 44 respectively disposed on both sides of the air deflector entry slot 45 . The wind deflector 31 passes through the wind deflector entry slot 45 to be rotatable. The first flow guide part 43 and the second flow guide part 44 respectively extend downward from the end of the flat plate part 41 , so as to guide the air discharged from both sides of the wind deflector 31 to flow downward.

Since the first flow guide portion 43 and the second flow guide portion 44 of this cover member 40 guide the exhaust air downward (in the discharge direction), eddy flow at the end of the cover member 40 can be minimized. Thereupon, the phenomenon that the air discharged through the discharge port 22 contacts the lower surface of the cover member 40 or the lower surface of the ceiling panel 20 can be minimized, so it can be prevented from contacting the cold air with the lower surface of the cover member 40 or the lower surface of the ceiling panel. 20 Condensation phenomenon.

Next, the operation of such a ceiling-mounted air conditioner will be described.

As shown in FIG. 2 , when the turbofan 11 is driven to rotate by the drive motor 12 , indoor air is sucked through the suction port 21 at the center of the ceiling panel 20 . The inhaled indoor air flows into the turbofan 11 through the opening 24 a of the air guide plate 24 after being purified by the filter 23 . Then, the air is discharged by swirling in the direction around the turbo fan 11 (to the side of the heat exchanger) by the rotational force of the turbo fan 11 . The air discharged from the turbo fan 11 is cooled by the heat exchanger 13 and then supplied to the indoor space again through the discharge ports 22 of the ceiling panel 20 .

When these operations are performed, as shown in FIG. 4 , the discharge of air is guided by the flow guide portion 42 of the cover member 40 at the discharge port 22 provided with the cover member 40 . That is, the discharge air is guided in the downward direction (discharge direction) by the flow guide portion 42 . Therefore, the present invention can smoothly discharge the discharge air downward while minimizing the vortex phenomenon near the cover member 40 . This minimizes the contact of the discharged air with the lower surface of the cover member 40 or the ceiling panel 20 , so that condensation on the lower surface of the cover member 40 and the ceiling panel 20 can be prevented.

In summary, the air conditioner provided by the present invention can minimize the occurrence of vortex around the cover member by guiding the flow of the discharged air through the flow guide portion of the cover member, thereby minimizing A phenomenon in which the exhausted air comes into contact with the lower surface of the cover part and the ceiling panel. Accordingly, dew condensation on the lower surface of the cover member and the ceiling panel can be prevented.
