The housing 20 is formed in a substantially hollow rectangular parallelepiped shape. The cabinet 20 has a cabinet main body 21 and a fan shroud 23. The cabinet main body 21 houses the outdoor fan 30. A blow-out opening 22 is formed in an upper surface 20a of the casing main body 21 (in other words, the upper surface 20a of the casing 20). A fan shroud 23 is mounted on the blowout opening 22. The fan shroud 23 covers the outdoor fan 30.
The housing 20 has a plurality of (in this example four) sides. An access door 24 is provided on the front side surface. An electronic component box 25 for housing electronic components is housed on the rear surface side of the access door 24. Note that a side surface (a front side surface) closest to the electronic component box 25 is defined as a first side surface 20b, and a side surface (a back side surface) opposite to the first side surface 20b is defined as a second side surface 20 c.
The outdoor fan 30 is a blower for generating an air flow through the inside of the cabinet 20. One outdoor fan 30 is provided in the cabinet 20 at each of left and right sides of the upper portion. The outdoor fan 30 generates an air flow that flows into the casing 20 from the side surface of the casing 20 and flows out from the outlet opening 22 through a heat exchanger not shown.
The antenna 40 is a means for communicating with the base station 2. The antenna (40) is provided on the upper surface (20a) of the housing (20) at a position that is distant from the outlet opening (22) in a plan view. Specifically, the antenna 40 is mounted on a corner portion on the left side (lower left side in fig. 2A) of the left fan shroud 23 near the front. As described above, the antenna 40 is arranged such that the distance between the antenna 40 and the second side 20c of the housing 20 is longer than the distance between the antenna 40 and the first side 20 b.
As shown in fig. 3, each antenna 40 is movable between a protruding position (a position indicated by a solid line in fig. 3) and a housing position (a position indicated by a two-dot chain line in fig. 3). The protruding position is a position where most (for example, 9 or more) of the antenna 40 protrudes from the upper surface 20a of the housing 20. The storage position is a position where all or most (for example, 9 or more) of the antenna 40 is stored in the housing 20. Therefore, a housing hole (not shown) for housing the antenna 40 in a vertically slidable manner is formed in the housing main body 21.
Effects of the first embodiment
The outdoor unit 10 of the air conditioning apparatus of the present embodiment includes: a casing 20 having a blow-out opening 22 formed on an upper surface 20 a; an outdoor fan 30 housed in the casing 20; and an antenna 40 provided on the housing 20 and used for communication with the base station 2, the antenna 40 being provided at a position away from the blowout opening 22 in the upper surface 20a of the housing 20 in a plan view. As described above, since the antenna 40 is provided on the upper surface of the outdoor unit 10, high-quality communication with the base station 2 can be performed. Further, since the antenna 40 is provided at a position distant from the outlet opening 22 in a plan view, it is less likely to be affected by the outlet air, and communication quality is less likely to be impaired.
In the outdoor unit 10 of the air conditioner of the present embodiment, the antenna 40 is movable between a protruding position where the antenna 40 protrudes from the upper surface 20a of the casing 20 and a storage position where the antenna 40 is stored in the casing 20. Therefore, high-quality communication can be performed between the outdoor unit 10 and the base station 2 via the antenna 40 located at the protruding position. On the other hand, when the outdoor unit 10 is transported, the antenna 40 is moved to the storage position, whereby damage to the antenna 40 can be avoided.
The outdoor unit 10 of the air conditioning apparatus according to the present embodiment includes the electronic component box 25 that is housed in the casing 20 and houses electronic components, and when a side surface closest to the electronic component box 25 among a plurality of side surfaces of the casing 20 is a first side surface 20b, and a side surface opposite to the first side surface 20b is a second side surface 20c, the antenna 40 is disposed such that a distance between the antenna 40 and the second side surface 20c is longer than a distance between the antenna 40 and the first side surface 20 b. Therefore, the wiring provided between the electronic component box 25 and the antenna 40 can be shortened as compared with the case where the antenna 40 is arranged such that the distance between the antenna 40 and the first side surface 20b is larger than the distance between the antenna 40 and the second side surface 20 c. Therefore, the wiring and other components can be easily provided.
The outdoor unit system 1 of the present embodiment includes a plurality of outdoor units 10 of the air-conditioning apparatus, and the outdoor unit system 1 is configured such that: the skip communication via the antenna 40 can be performed between the outdoor units 10 of the air conditioners. Therefore, when it is difficult for any outdoor unit 10 of the plurality of outdoor units 10 to directly communicate with the base station 2, the outdoor unit 10 can indirectly communicate with the base station 2 via another outdoor unit 10 having a good communication state with the base station 2.
