The air that has passed through the use-side heat exchanger 3 by the second fan 4 passes through the inside of the bell mouth 26, passes through the inside of the fan 4, and is blown out to the outlets 31a to 31d. In other words, the outside of the bellmouth is not only an empty space, but even if an object is placed here, the flow of air is not affected.

(5) Features (5-1)
The outdoor air conditioner of the present embodiment includes a compressor 1, a heat source side heat exchanger 6, a use side heat exchanger 3, a first fan 7, and a second fan 4 in one casing 10. Thus, two or more air outlets 31a and 31c capable of simultaneously blowing air passing through the use side heat exchanger 3 in at least two different directions are provided.

  Since the present embodiment has such a configuration, unlike a conventional air conditioner arranged near a wall in a room, it is possible to cool or heat a large area. Further, unlike an air conditioner called a so-called spot cooler, an area where cooling or heating can be performed is widened.

  In the outdoor air conditioner of the present embodiment, the outlets 31a to 31d are arranged in the casing 10 without using a duct or the like protruding from the casing. Therefore, the distance between the second fan 4 and the outlets 31 a to 31 d is short, and the attenuation of the wind speed is small inside the device 100. In addition, it is possible to cool or heat various areas including the periphery of the casing 10.

(5-2)

  Panel 300 is made of resin. As shown in FIG. 8A, one panel 300 has four holes 301 formed therein. The flap units 40 are attached to the holes 301, respectively.

  For the panel 300 or the flap unit 40, a weather resistant material may be used, or the surface may be subjected to a weather resistant treatment. Here, examples of the weather resistant material include an acrylonitrile styrene polymer, but are not limited thereto.

  As shown in FIG. 8B, the flap unit 40 has a first flap 401, a second flap 402, and a wind direction adjustment knob 403. Air is blown out from a gap between the flaps 401 and 402 of the flap unit 40 or a gap between the flaps 401 and 402 and a frame around the flap. The flap unit 40 is made of resin. It may be made of metal. The first flap 401 is arranged outside the second flap 402. The first flap 401 can change the air blowing direction in the horizontal direction. The second flap 402 can change the air blowing direction in the vertical direction. In the present embodiment, the plurality of first flaps 401 belonging to the same flap unit 40 are designed to face in the same direction. The same applies to the second flap 402. By moving the wind direction adjustment knob 403 up and down, the inclination of the second flap 402 can be changed, and the wind direction can be changed up and down. By moving the wind direction adjustment knob 403 left and right, the inclination of the first flap 401 can be changed, and the wind direction can be changed left and right. By moving the wind direction adjustment knob 403, the outlet can be closed. In the present embodiment, four flap units 40 are arranged on each of four side surfaces 20a to 20d. Each flap unit 40 can adjust and close the wind direction by independently moving the wind direction adjustment knob 403.

  The orientation of the flaps 401 and 402 may be manually controlled as in the present embodiment, or may be automatically controlled. In order to manually operate the flaps 401 and 402, the wind direction adjustment knob 403 needs to be accessible from outside. Therefore, for example, a portion of the decorative plate that is in contact with the front surface of the wind direction adjusting knob 403 may be perforated. The decorative panel may be removable or open. As an example of the automatic control, the direction of the wind blown from a certain side surface may be changed according to time. Alternatively, blowing from a blowing port from a certain side may be sealed by a user's switch operation.

(8) Features of Second Embodiment In the air-conditioning apparatus 101 of the second embodiment, all of (5-1) to (5-8) of the first embodiment apply. In addition, it has the following features.

(8-1)
A panel 300 having a plurality of holes is arranged at the outlets 31a to 31d of the present embodiment. The outlets 31a to 31d are smaller than in the case where the panel 300 is not provided, so that the direction and amount of the blown air can be easily controlled. Further, by controlling a plurality of holes independently, it is possible to close some of the holes or to change the air blowing directions.

(8-2)
The flaps 401 and 402 of the present embodiment are detachable from the casing 10. In the case of the present embodiment, more specifically, the panel 300 is detachable from the frame 25 attached to the casing 10, and the flap unit 40 is detachable from the panel 300. The flap unit 40 includes flaps 401 and 402. Therefore, the flaps 401 and 402 are detachable from the casing 10.

  Since the outdoor air-conditioning apparatus 101 of the present embodiment is arranged outdoors, the flaps 401 and 402 are easily stained. If the flaps 401 and 402 are dirty, some of the deposits may corrode the flaps 401 and 402, and if the deposits are blown off, the deposits may not reach the user and may smell. . The outdoor air conditioner 100 of the present embodiment is easy to clean because the flaps 401 and 402 are detachable. If the flap can be removed from the outdoor air conditioner, the flap can be more easily cleaned.

  While the embodiments of the present disclosure have been described above, it will be understood that various changes in form and details can be made without departing from the spirit and scope of the present disclosure described in the claims. .
