Are provided in the vertical direction.

また、右第２側面パネル５ｂには、図２及び図３に示すように、前述の空気取り入れ部１２が縦方向に例えば４つ設けられている。この空気取り入れ部１２は、図６に示すように、右第２側面パネル５ｂの後部に機械室側に凹んで形成される面が、背面パネル３の折り曲げパネル３ａにより覆われて形成された第１空気導入口１２ａを成し、さらに、右第２側面パネル５ｂの後部を凹んで形成される背面パネル３と対向する面が開口されて、折り曲げパネル３ａとで第２空気導入口１２ｂが形成されている。   Moreover, as shown in FIG.2 and FIG.3, the above-mentioned air intake part 12 is provided in the right 2nd side surface panel 5b in the vertical direction, for example, four. As shown in FIG. 6, the air intake portion 12 is formed by covering the rear surface of the second right side panel 5 b with the folding panel 3 a of the rear panel 3 with the surface formed to be recessed toward the machine room. The first air inlet 12a is formed, and a surface facing the rear panel 3 formed by denting the rear portion of the right second side panel 5b is opened, and the second air inlet 12b is formed by the bent panel 3a.

前記のように構成された空気調和機の室外機１００においては、送風機が駆動すると、外部の空気は、筐体１の背面の開口部９から吸引されて熱交換器１０を通過し、送風機を介して吹出口７から外部へ吹き出される。熱交換器１０は、暖房運転のときには蒸発器として吸引される空気と熱交換し、冷房運転のときには凝縮器として空気と熱交換する。   In the outdoor unit 100 of the air conditioner configured as described above, when the blower is driven, external air is sucked from the opening 9 on the back surface of the housing 1 and passes through the heat exchanger 10, It blows out from the blower outlet 7 through. The heat exchanger 10 exchanges heat with air sucked as an evaporator during heating operation, and exchanges heat with air as a condenser during cooling operation.

送風機の駆動中において、機械室内の空気は、送風機により吹出口７側へ送り込まれる空気によって、電気品モジュールユニット１１を介して誘引される。この空気の誘引作用により、室外機１００の右側面パネル５周辺の空気は、空気取り入れ部１２の第１空気導入口１２ａに取り込まれ、さらに第２空気導入口１２ｂから機械室内に導かれて背面に当たる。そして、機械室内に導かれた空気は上昇して、電気品モジュールユニット１１内を介して送風機室内に引き込まれる。また、雨天のときに雨水の水滴が飛散して空気と共に第１空気導入口１２ａに取り込まれることがあるが、その水滴は、第１空気導入口１２ａに対向する奥の壁面に当たり、直接機械室内に導かれることはない。   While the blower is being driven, the air in the machine room is attracted via the electrical module unit 11 by the air sent to the outlet 7 by the blower. By this air attracting action, the air around the right side panel 5 of the outdoor unit 100 is taken into the first air introduction port 12a of the air intake unit 12, and further led into the machine room from the second air introduction port 12b and back. It hits. Then, the air guided into the machine room rises and is drawn into the blower room through the electrical module unit 11. In addition, in rainy weather, rainwater droplets may scatter and be taken into the first air inlet 12a together with the air, but the waterdrop hits the inner wall facing the first air inlet 12a and directly into the machine room. Will not be led to.

以上のように空気取り入れ部１２から機械室内に取り込まれた空気は、機械室の背面に向かっているため、仮に雨水等が第１及び第２空気導入口１２ａ、１２ｂを通じて浸入したとしても、室外機１００の内部に設けられた電気品モジュールユニット１１には影響を与えることはない。このように、空気取り入れ部１２から機械室内に取り込まれた空気が機械室の背面に向かうので、新たに雨水の浸入を抑える防止具等の部品を設けることなく、雨水等の浸入対策を施した構造を有する空気調和機の室外機１００を提供できる。   As described above, since the air taken into the machine room from the air intake part 12 is directed toward the back of the machine room, even if rainwater or the like enters through the first and second air inlets 12a and 12b, There is no influence on the electrical module unit 11 provided in the machine 100. Thus, since the air taken into the machine room from the air intake part 12 goes to the back of the machine room, measures against the intrusion of rainwater and the like were taken without newly providing parts such as a preventer for suppressing the ingress of rainwater. The outdoor unit 100 of an air conditioner having a structure can be provided.

また、空気取り入れ部１２の手前に配管接続部１４と接続される冷媒配管により、空気取り入れ部１２が冷媒配管で目隠しされる格好となるので、空気取り入れ部１２が意匠性に与える影響は小さくなり、室外機１００そのものの意匠性を損なうことがない。   Further, the refrigerant pipe connected to the pipe connection part 14 in front of the air intake part 12 makes the air intake part 12 blinded by the refrigerant pipe, so that the influence of the air intake part 12 on the design is reduced. The design of the outdoor unit 100 itself is not impaired.
