Effects of embodiment one
The attachment 50 of the present embodiment is attached to an indoor unit 30, the attachment 50 includes a discharge unit 56 and a filter 57 for providing an additional function to the indoor unit 30, and the attachment 50 is attached to the rear surface of the indoor unit 30, wherein the indoor unit 30 is an indoor unit of a ceiling-mounted air conditioning system 10 having a suction port 36 on the rear surface and housing an indoor heat exchanger 37 and an indoor fan 38. Therefore, the additional device 50 provides an additional function to the indoor unit 30. On the other hand, since the attachment 50 is attached to the back surface of the indoor unit 30 provided with the suction port 36, it is less likely to protrude downward than when attached to the bottom surface 33 of the indoor unit 30. Therefore, even when the attachment 50 is attached to the indoor unit 30, the indoor person does not easily feel a sense of pressure.
The lower surface 53 of the attachment 50 of the present embodiment is located on the same plane as the lower surface 33 of the indoor unit 30. Therefore, the lower surface 53 of the attachment 50 is located at the same position as the lower surface 33 of the indoor unit 30 in the height direction. Therefore, the attachment 50 is further prevented from protruding downward. Further, the feeling of pressure of the indoor unit 30 to which the attachment 50 is attached can be reduced, and the visual beauty can be improved.
The attachment 50 of the present embodiment includes a suction port 54 provided on the rear surface and an air outlet 55 provided on the front surface, and the air outlet 55 of the attachment 50 communicates with the suction port 36 of the indoor unit 30. Therefore, the indoor air is sucked from the suction port 54 of the attachment 50, flows through the attachment 50, and is then sucked into the indoor unit 30 through the air outlet 55 of the attachment 50 and the suction port 36 of the indoor unit 30.
The air conditioner 10 of the present embodiment includes the attachment 50 of the present embodiment and the indoor unit 30, and the indoor unit 30 has the suction port 36 on the rear surface and is attached to the rear surface by the attachment 50. Therefore, even if the attachment 50 is attached to the indoor unit 30 of the air conditioner 10, the feeling of pressure on the indoor person is not easily generated.
The air conditioner 10 of the present embodiment includes a first electrical component 39 provided in the indoor unit 30 and a second electrical component 58 provided in the attachment 50, both the first electrical component 39 and the second electrical component 58 being provided on the right side surface of the indoor unit 30, and the air conditioner 10 includes a wire 70 connecting the first electrical component 39 and the second electrical component 58. Therefore, both the first electrical component 39 provided in the indoor unit 30 and the second electrical component 58 provided in the attachment 50 are provided on the right side surface side, and are connected by the wiring 70. Therefore, the wiring 70 extends across the indoor unit 30 and the attachment 50, but since the first electrical equipment 39 and the second electrical equipment 58 are disposed close to each other, the wiring 70 can be made short, and the wiring 70 can be easily disposed.
In the air conditioner 10 of the present embodiment, the air outlet 43 is formed in the front surface of the indoor unit 30, and the air conditioner 10 includes an airflow direction adjustment blade 47 that can adjust the airflow direction of the air flowing out from the air outlet 43 to be upward from the horizontal direction. Therefore, the direction of the air flowing out from the air outlet 43 of the indoor unit 30 can be adjusted to be higher than the horizontal direction, and the air can be caused to reach a remote place.
The air conditioner 10 of the present embodiment includes a plurality of the airflow direction adjustment vanes 47. Therefore, compared to the case where only one airflow direction adjustment blade 47 is included, the wind pressure distribution around the air outlet 43 of the indoor unit 30 can be made uniform.
The air conditioning apparatus 10 according to the present embodiment includes the indoor heat exchanger 37 housed in the indoor unit 30 and the outlet passage 44 extending from the indoor heat exchanger 37 in a direction toward the outlet 43, and has a first lower end 45 defined as a lower end of an end portion of the outlet passage 44 on the side of the indoor heat exchanger 37 into which air flows, and a second lower end 46 defined as a lower end of an end portion of the outlet passage 44 on the side of the outlet 43 from which air flows out, the second lower end 46 being located lower than the first lower end 45 in the height direction. Therefore, in the blowout passage 44, the air flows from the end portion side having the first lower end 45 toward the end portion side having the second lower end 46. Here, since the second lower end 46 is located below the first lower end 45 in the height direction and the outlet passage 44 faces downward as it goes from the inlet to the outlet, air is blown out substantially downward than horizontally at the outlet of the outlet passage 44, in other words, at the outlet 43, regardless of the adjustment of the wind direction by the wind direction adjustment blade 47. Further, the airflow direction of the air flowing out from the air outlet 43 can be adjusted to be upward from the horizontal direction by the airflow direction adjusting blade 47. As described above, according to the air conditioner 10 of the present embodiment, air can be blown out over a wide range from below the horizontal to above the horizontal at the air outlet 43 of the indoor unit 30.

Therefore, even when the attachment 50 is attached to the indoor unit 30, the indoor person does not easily feel a sense of pressure.
The lower surface 53 of the attachment 50 of the present embodiment is located on the same plane as the lower surface 33 of the indoor unit 30. Therefore, the lower surface 53 of the attachment 50 is located at the same position as the lower surface 33 of the indoor unit 30 in the height direction. Therefore, the attachment 50 is prevented from protruding downward, and the feeling of pressure of the indoor unit 30 to which the attachment 50 is attached can be reduced, and the visual appearance can be improved.
The attachment 50 of the present embodiment includes a suction port 54 provided on the rear surface and an air outlet 55 provided on the front surface, and the air outlet 55 of the attachment 50 communicates with the suction port 36 of the indoor unit 30. Therefore, the indoor air is sucked from the suction port 54 of the attachment 50, flows through the attachment 50, and is then sucked into the indoor unit 30 through the air outlet 55 of the attachment 50 and the suction port 36 of the indoor unit 30.
The air conditioner 10 of the present embodiment includes the attachment 50 of the present embodiment and the indoor unit 30, and the indoor unit 30 has the suction port 36 on the rear surface and is attached to the rear surface by the attachment 50.
