In addition, there is a considerable concern about the outer edge of the opening / closing part when the operation is stopped from entering the inside of the main body. However, in the first embodiment, the opening / closing operation is stopped while using three blades. It can also be expected that the entry of unwanted dust and the like into the main body is suppressed by suppressing the portion by two sheets.

That is, it can be said that the blade chord length is changed by the wind direction without replacing the blade itself. In this way, virtual blades with virtual string lengths longer than the individual string lengths of individual blades can be obtained, so that when blowing horizontally, the flow of air released upward from the cross-flow fan is utilized by utilizing the long virtual string length. , It can be largely turned forward, and the wind direction controllability can be greatly improved.

Since the first blade 4a1 and the second blade 4a2 are arranged in series in a state where the gap 20 is secured in this way, the air during cooling passes through the first blade 4a1 and then from the gap 20 with the second blade 4a2. Since it flows to both the upper and lower surfaces of the second blade 4a2 and the temperature difference between both surfaces of the second blade 4a2 becomes small, dew condensation is suppressed and the quality can be improved.

Due to the action of the warp direction of the surfaces of the first blade 4a1 and the second blade 4a2, the airflow easily flows between the first blade 4a1 and the second blade 4a2, and the effect of suppressing dew condensation is It is higher.
  • the second blade 4a2 partially exits from the air outlet 3 when it is blown upward, and from the air outlet 3 when it is horizontally blown as shown in FIG. It completely goes out (the entire second blade 4a2 goes out from the outlet 3). For this reason, in the part of the 2nd blade
  • the second blade 4a2 is arranged in parallel with the first blade 4a1 when top blowing. Furthermore, the surface of the second blade 4a2 that faces the first blade 4a1 is a convex shape that protrudes toward the first blade 4a1, and the surface of the first blade 4a1 that faces the second blade 4a2 is the second blade 4a2.
  • the first blade 4a1 and the second blade 4a2 rotate and move so as to have a convex shape projecting toward each other. For this reason, since the airflow flowing between the first blade 4a1 and the second blade 4a2 flows in the region surrounded by the convex shape of the first blade 4a1 and the convex shape of the second blade 4a2, it is gradually reduced.
  • the blow-out opening is opened only on the upper surface of the main body and is not opened on the front surface.
  • Motor noise, wind noise of cross-flow fan, refrigerant circulation sound in heat exchanger) are prevented from leaking directly forward, improving wind direction controllability by blades not restricted by design conditions, and noise Coexistence with suppression is achieved.
  • the second blade protrudes outside the main body and is arranged in series with the first blade, even in a state where only the upper surface of the main body is opened, Suitable horizontal blowing is possible, and it is possible to achieve both noise suppression and comfort.
