- the present invention also relates to an air conditioner provided with an inspection window for checking dirt on the drain pan.
- a ceiling-mounted air conditioner (for example, a four-way cassette type air conditioner) has a unit main body that has a function of adjusting air temperature and blowing air.
- the unit main body is suspended from the ceiling by hanging bolts provided on beams or the like in the ceiling space.
- the unit body includes an indoor heat exchanger and an air blower.
- a drain pan is provided below the indoor heat exchanger of the unit main body to receive and collect drain water condensed by the indoor heat exchanger. Drain water accumulated in the drain pan is discharged to the outside of the unit main body through a discharge port provided with a drain pump and a drain pipe.
- the method of removing the drain pan from the case body of the indoor unit and checking the contamination state of the drain pan has the problem that the inspection work is complicated and takes a long time.

- Check for dirt on the inside of the drain pan vane motors and sensors are provided in areas of the decorative panel covered by the corner panels, and there are restrictions on the positions where the openings can be formed and the areas of the openings. Therefore, the area of the through hole of the drain pan and the area of the transparent member attached to the through hole tend to be small.
- the present disclosure is intended to solve the above problems, and even when the area of the through hole of the drain pan is limited, while suppressing the positional deviation of the window and the reflector, the visibility of dirt inside the drain pan is improved. To provide an inspection window and an air conditioner that can be secured.
- an inspection window includes a window portion formed of a light-transmitting material, a first support portion provided in the window portion, and a window portion supported by the first support portion. and a reflecting portion supported above the window portion with a predetermined gap in between, the reflecting portion having a first surface connected to the first support portion and facing the first surface a second surface, and the reflecting portion has a first reflecting structure on the second surface for reflecting light transmitted through the window portion, the window portion, the first supporting portion, and the reflecting portion is integrally molded with a light transmissive material.
- the window portion, the reflector, and the pillar are continuously and integrally formed. Even if the area of the inspection window of the drain pan is limited, the window installed in the through hole can be prevented while minimizing misalignment between the window and the reflector. It is possible to ensure the visibility of dirt on the part.

図8に示すように、第2の取付部106は、窓部102の外縁に沿って、破線102Lで窓部102と接続し、第1の取付部107に接続して設けられる。第2の取付部106は、内側に円柱状の空間を有する円筒状の形状を有する。
第1の取付部107は第2の取付部106の下端から放射状に外側に延伸する一定の厚みをもった形状を有する。
図11は、点検窓100の成形に使われる金型の断面図である。反射板下面104bと、窓部上面102aと、第1の取付部107の上面107aと、を互いに平行とすることで、キャビティ500、第1のスライド502、第2のスライド503及びコア501で金型を形成し、点検窓100を一体で成形することができる。また図11において、点検窓100の上側をキャビティ500、点検窓100の下側をコア501としているが、逆でもよい。
ドレンパン19の貫通穴19bを通過した室内からの光の一部は、窓部102の第1の面である窓部下面102bに入射する。貫通穴19bからの入射光の一部(光L1)は、窓部102および反射板104が光を透過する材料で製作されていることにより、窓部102および反射板104内を透過し反射板上面104a上に設けられた反射構造105の表面(反射面108)に到達する。反射構造105は、上方に凸となる四角錐体105aを少なくとも一つ含む。反射板104にこの四角錐体105aのような反射構造105を設けることで、ドレンパン19の貫通穴19bを通過し、反射板104の反射構造105に到達した光の一部が、四角錐体105aを構成する面により反射される。四角錐体105aの複数の面で反射した反射光L2は、最終的な進行方向を、元の入射光の方向の逆方向として貫通穴19bを通過し、室内に戻っていく。
図13に示されるように、点検窓100は、反射構造105として、四角錐体105aの代わりに、上方に凸となる球面105bを、反射板上面104aに少なくとも一つ形成してもよい。言い換えると、点検窓100は、反射構造105として、少なくとも一つの上方に凸となる球面105bを反射板上面104aに有してもよい。
また、図8、図13、図14、図15及び図16では、柱103の形状は円柱状としたが、これに限定されない。一例として、図17のように柱103は直方体であってもよい。
このような点検窓100をドレンパン19の貯水部19fに取付けた構造を図19に示す。図19は、シール材26を介してドレンパン19に固定された図18に示す点検窓100を示すものであり、図6の断面線B-B´と同じ向きに、ドレンパン19と点検窓100の断面を示した図である。なお、図19において、排水口24周りの構成は省略されている。図18に示す点検窓100をドレンパン19の貯水部19fに取付けるときは、貯水部19fの底面19aに、底面19aより一段低く形成された取付面51を形成し、取付面51に円筒形の貫通穴19jを形成する。そして、取付面51上にシール材26を設け、取付面51の上方から、窓部102を取付面51に圧着して、点検窓100を、シール材26を介して取付面51に固定する。窓部上面102aは、貯水底部19aの上面(貯水部19fの底面19a)と高さが略等しく、水平である。
このような構成においても、貫通穴19jを通して反射面108の反射光の強度を点検者が見ることで、点検者が窓部上面102aの汚れの付着状態、すなわちドレンパン19の貯水底部19aの汚れの付着状態を把握することができる。そのため、点検者がドレンパン19を筐体12から取り外して内部を確認せずとも、ドレンパン19の清掃時期を判断することができる。
本実施の形態では、点検窓100は、ポリメタクリル酸メチル、ポリエチレンテレフタレート、ポリカーボネート、エポキシ、ポリアリレートなどの透明樹脂を材料とし、射出成形することにより成形される。
本開示の実施の形態2の点検窓200について、図20、図21、図22、図23、図24及び図25を用いて説明する。実施の形態2の点検窓200は、実施の形態1の柱103に替えて、2つの柱、すなわち第1の柱201及び第2の柱202を備える。その他の構成要素については実施の形態1と同じのため、それらの構成要素についての説明は省略する。なお、図20、図21、図22、図23、図24及び図25中、実施の形態1内で使用された符号と同一符号は同一部分を指す。
実施の形態3の点検窓300について、図27、図28及び図29を用いて説明する。この実施の形態3の点検窓300は、実施の形態1の反射板104に替えて、上方に凸である反射板上面301aを有する反射板301を備える。その他の構成要素については実施の形態1と同じであるので、それらの構成要素についての説明は省略する。なお、図27、図28及び図29中、実施の形態1内で使用された符号と同一符号は同一部分を指す。
反射板301は、図29の破線に示される、上方に凸となる曲面を有する反射板上面301aと、反射板上面301aに設けられる反射構造302とを備える。
実施の形態4の点検窓400について図30を用いて説明する。実施の形態4の点検窓400は、実施の形態1の反射板104に替えて、反射板側面401cに反射構造402を備えた反射板401を備えるという点で実施の形態1と異なる。その他の構成要素については実施の形態1と同じのため、それらの構成要素についての説明は省略する。
