The insulation 32 has a heat insulating portion 32a and a wind shielding portion 32b.
The heat insulating portion 32a is a portion provided in the central region of the plate member 31 and exhibits a heat insulating function. The heat insulating portion 32a is made of foamed polyethylene, for example. The thickness dimension of the heat insulating portion 32 a is substantially equal to the thickness dimension of the side panel 11 .
The wind shielding portion 32b is a portion provided so as to surround the entire periphery of the heat insulating portion 32a, and exerts a wind shielding function between itself and the opening 21 by coming into contact with a stepped portion 21a, which will be described later. The wind shield part 32b is made of foamed ethylene or propylene rubber. The thickness dimension of the windshield part 32b is smaller than the thickness dimension of the side panel 11, thereby forming a stepped part with the heat insulation part 32a.
　蓋部材３０は、板材３１の穴３１ａに挿通された２本のネジ５７によってサイドパネル１１に締結される。
　板材３１がサイドパネル１１に締結されたとき、インシュレーション３２が開口部２１の内側に嵌合するので、蓋部材３０によって気密性を保った状態で開口部２１を閉塞することができる。 The lid member 30 is fastened to the side panel 11 with two screws 57 inserted through the holes 31 a of the plate member 31 .
When the plate member 31 is fastened to the side panel 11 , the insulation 32 fits inside the opening 21 , so the opening 21 can be closed while maintaining airtightness with the lid member 30 .
　また、開口部２１の周縁に段部２１ａを設けておけば、インシュレーション３２の遮風部３２ｂを当接させることで、インシュレーション３２による遮風機能を発揮させることができる。 In addition, if a stepped portion 21a is provided on the peripheral edge of the opening 21, the wind shielding function of the insulation 32 can be exhibited by bringing the wind shielding portion 32b of the insulation 32 into contact with the stepped portion 21a.
　なお、蓋部材３０の板材３１及びインシュレーション３２の形状は、側面視したときに点対称形状であることが好ましい。点対称形状としては、上記で説明した四角形状の他に、正方形状、円形状等が例示される。これによって、筐体１０を側面視したとき、蓋部材３０を所定の角度で回転させた任意の位置で位置決めしながら蓋部材３０を開口部２１に取り付けることができる。
　特に、図１０に示すように、蓋部材３０の板材３１及びインシュレーション３２を正方形状にするととともに板材３１の上下左右の４箇所に穴３１ａを形成してすることで、筐体１０を側面視したとき、蓋部材３０を９０°ずつ回転させた任意の位置で位置決めしながら蓋部材３０を開口部２１に取り付けることができる。
　この場合、開口部２１の形状もインシュレーション３２の形状に対応した点対称形状とされていることは言うまでもない。 The plate member 31 and the insulation 32 of the lid member 30 preferably have a point-symmetrical shape when viewed from the side. Examples of the point-symmetrical shape include a square shape, a circular shape, and the like, in addition to the square shape described above. Accordingly, when the housing 10 is viewed from the side, the lid member 30 can be attached to the opening 21 while being positioned at an arbitrary position where the lid member 30 is rotated by a predetermined angle.
In particular, as shown in FIG. 10, the plate member 31 and the insulation 32 of the lid member 30 are formed in a square shape, and the plate member 31 is formed with holes 31a at four locations on the top, bottom, left, and right, so that the housing 10 can be viewed from the side. Then, the lid member 30 can be attached to the opening 21 while positioning the lid member 30 at an arbitrary position rotated by 90°.
In this case, it goes without saying that the shape of the opening 21 also has a point-symmetrical shape corresponding to the shape of the insulation 32 .
　以上の通り説明した開口部２１、蓋部材３０及びドレンソケット４４は、室内機１の両側のサイドパネル１１に設けられていてもよい。
　この場合、一方のサイドパネル１１に建屋の壁が近接するように室内機１を設置した場合でも、他方のサイドパネル１１に形成された開口部２１からドレンソケット４４を目視で確認することができる。 The opening 21 , the lid member 30 and the drain socket 44 described above may be provided on the side panels 11 on both sides of the indoor unit 1 .
In this case, even if the indoor unit 1 is installed so that the wall of the building is close to one side panel 11, the drain socket 44 can be visually confirmed through the opening 21 formed in the other side panel 11. .
　また、図７に示すように、板材３１の表面（インシュレーション３２を設けた面と反対側の面）に開閉可能な環状のクリップ３３を設けてもよい。これによって、作業者がクリップ３３を摘まむことができるので蓋部材３０の取り外しが容易になる。また、クリップ３３に配線類を掛けることもできる。 Further, as shown in FIG. 7, an openable and closable annular clip 33 may be provided on the surface of the plate member 31 (the surface opposite to the surface on which the insulation 32 is provided). As a result, the operator can pick up the clip 33, so that the lid member 30 can be easily removed. Wires can also be hung on the clip 33 .
　本実施形態では、以下の効果を奏する。
　すなわち、筐体１０のサイドパネル１１には、熱交換室１９に連通するとともに筐体１０の外部からドレンソケット４４を臨むことができる開口部２１が形成されているので、筐体１０やドレンパン４３等の分解作業を行うことなく、作業員がドレンパン４３上にあるドレンソケット４４近傍の汚れや詰まりを目視で確認することができる。また、作業員が開口部２１を介してその汚れや詰まりを掃除することができる。 The present embodiment has the following effects.
That is, the side panel 11 of the housing 10 is formed with an opening 21 that communicates with the heat exchange chamber 19 and allows the drain socket 44 to be seen from the outside of the housing 10. A worker can visually check dirt and clogging in the vicinity of the drain socket 44 on the drain pan 43 without performing any disassembly work. Also, an operator can clean the dirt and clogs through the opening 21 .
　また、開口部２１は、熱交換器４２よりもファン室１８側の熱交換室１９に連通しているので、開口部２１から直接的にドレンソケット４４を目視で確認することができる。 Also, since the opening 21 communicates with the heat exchange chamber 19 on the fan chamber 18 side rather than the heat exchanger 42 , the drain socket 44 can be visually confirmed directly from the opening 21 .
　また、蓋部材３０は、開口部２１の周囲にある筐体１０のサイドパネル１１に当接する板材３１及び開口部２１の内側に嵌合するインシュレーション３２を有しているので、蓋部材３０によって気密性を保って開口部２１を閉塞することができる。 In addition, since the lid member 30 has a plate member 31 that contacts the side panel 11 of the housing 10 around the opening 21 and an insulation 32 that fits inside the opening 21, the lid member 30 The opening 21 can be closed while maintaining airtightness.
　また、開口部２１の形状及び蓋部材３０の形状は、筐体１０を側面視したとき、正方形状とされているので、筐体１０を側面視したとき、蓋部材３０を９０°ずつ回転させた任意の位置で位置決めしながら蓋部材３０を開口部２１に取り付けることができる。 The shape of the opening 21 and the shape of the lid member 30 are square when the housing 10 is viewed from the side. The lid member 30 can be attached to the opening 21 while being positioned at an arbitrary position.
