Then, the operator opens and closes the service panel 62 on the side surface of the ceiling-embedded air conditioner 1 and performs maintenance of components and the like inside the ceiling-embedded air conditioner 1. In recent years, in order to secure the height of the ceiling in the living room, there is a tendency to reduce the space behind the ceiling, and a thin-type ceiling-embedded air conditioner that reduces the height of the main body of the ceiling-embedded air conditioner 1 The device 1 has been required.
　天井埋込形空気調和装置１の本体の薄型化により、天井埋込形空気調和装置１の側面にあるサービス用パネル６２のサイズが小さくなり、側面からのメンテナンスが困難になった。そこで、清掃程度の軽度のメンテナンスを行う場合でも、天井埋込形空気調和装置１の本体の底面にメンテナンスを行うためのサービススペース６１を設け、そこからメンテナンスを行う必要が生じた。 The thinning of the main body of the ceiling-embedded air conditioner 1 reduces the size of the service panel 62 on the side surface of the ceiling-embedded air conditioner 1, making it difficult to perform maintenance from the side surface. Therefore, even when performing light maintenance such as cleaning, it is necessary to provide a service space 61 for maintenance on the bottom surface of the main body of the ceiling-embedded air conditioner 1 and perform maintenance from there.
　しかし、建築物側の制約等で十分なサービススペース６１を確保できなかったり、天井の点検口６０を設けることができないことがある。このため、天井埋込形空気調和装置１のメンテナンス時には天井を開口し、再度天井を閉口させるなどの大掛かりな作業又は工事が必要となる問題があった。 However, due to restrictions on the building side, sufficient service space 61 may not be secured, or the ceiling inspection port 60 may not be provided. For this reason, there has been a problem that a large-scale operation or construction such as opening the ceiling and closing the ceiling again is required during maintenance of the ceiling-embedded air conditioner 1.
　そこで、上記の問題を解決するために天井埋込形空気調和装置の下方に天井開口を形成し、取り外し可能なパネルを当該天井開口に設置する。そして、パネルを取り外すことで天井埋込形空気調和装置の下側の天井開口からメンテナンスを容易に行えるようにした天井埋込形空気調和装置が提案されている（例えば特許文献１参照）。 Therefore, in order to solve the above problem, a ceiling opening is formed below the ceiling-embedded air conditioner, and a removable panel is installed in the ceiling opening. Then, a ceiling-embedded air conditioner has been proposed in which maintenance can be easily performed by removing the panel from the lower ceiling opening of the ceiling-embedded air conditioner (see, for example, Patent Document 1).

The air outlet 53 is formed toward the wall surface 6.
　なお、ファン８ａは本発明における「送風機」に相当する。また、送風機部１９は本発明における「空気吸込側筐体部」に相当する。また、熱交換器部２０は本発明における「空気吹出側筐体部」に相当する。また、ファンプレート１７は本発明における「第一の仕切り体」に相当する。 The fan 8a corresponds to the “blower” in the present invention. The blower unit 19 corresponds to the “air suction side casing” in the present invention. Moreover, the heat exchanger part 20 is corresponded to the "air blowing side housing | casing part" in this invention. The fan plate 17 corresponds to the “first partition” in the present invention.
［天井埋込形空気調和装置１の動作］
　天井埋込形空気調和装置１のファン８ａが回転すると、送風機部１９の内部のファンケース８の吸込側が負圧となり、居室内の空気は、図１の矢印に示す通り天井面に設置された格子状部材３を通り、天井埋込形空気調和装置１の内部へ吸引される。なお、図１中の矢印は空気の流れを示す。天井埋込形空気調和装置１の内部へ吸引される空気は、エアフィルタ７及びファンケース８を通り、熱交換器部２０に吹き出される。熱交換器部２０に吹き出された空気は、熱交換器９を通過し、天井埋込形空気調和装置１を出て、ダクト１０及び天井吹出口を通って再び居室内に吹き出される。冷房運転時において、居室内に吹き出される空気は、冷媒により冷却された熱交換器９を通過することで冷やされる。 [Operation of ceiling-embedded air conditioner 1]
When the fan 8a of the ceiling-embedded air conditioner 1 rotates, the suction side of the fan case 8 inside the blower unit 19 becomes negative pressure, and the air in the room is installed on the ceiling surface as shown by the arrows in FIG. The air passes through the lattice member 3 and is sucked into the ceiling-embedded air conditioner 1. In addition, the arrow in FIG. 1 shows the flow of air. The air sucked into the ceiling-embedded air conditioner 1 passes through the air filter 7 and the fan case 8 and is blown out to the heat exchanger unit 20. The air blown out to the heat exchanger section 20 passes through the heat exchanger 9, exits the ceiling-embedded air conditioner 1, and is blown out again into the living room through the duct 10 and the ceiling outlet. During the cooling operation, the air blown into the living room is cooled by passing through the heat exchanger 9 cooled by the refrigerant.
　ここで、冷房運転時において、熱交換器９内の冷媒と、居室内に吹き出される空気とが熱交換を行う際に、熱交換器９内の冷媒の温度が、空気中に含まれる水蒸気の露点温度以下となる場合、熱交換器９に凝縮水（結露）が生じる。そこで、この凝縮水を貯留し、排水するためにドレンパン１１が熱交換器９の下方に設けられている。 Here, during the cooling operation, when the refrigerant in the heat exchanger 9 exchanges heat with the air blown into the living room, the temperature of the refrigerant in the heat exchanger 9 is the water vapor contained in the air. When the temperature is lower than the dew point temperature, condensed water (condensation) is generated in the heat exchanger 9. Therefore, a drain pan 11 is provided below the heat exchanger 9 for storing and draining the condensed water.
　熱交換器９にて生じた凝縮水は、熱交換器９の下方に設置されたドレンパン１１に流れ、ドレンパン１１の底部に設けられた傾斜によって、一カ所に集められる。凝縮水が集まるドレンパン１１の最深部にはドレンポンプ１２が設置され、ドレンポンプ１２の運転により、ドレンパン１１の最深部に貯留した凝縮水が排水口１４（図２参照）を介して天井埋込形空気調和装置１の外部へ排水される。また、ドレンパン１１の最深部の端部には、水抜き用の水抜き口１３が設けられ、通常時はゴム栓などで塞がれている。 The condensed water generated in the heat exchanger 9 flows to the drain pan 11 installed below the heat exchanger 9 and is collected in one place by the inclination provided at the bottom of the drain pan 11. A drain pump 12 is installed at the deepest part of the drain pan 11 where condensed water collects, and the condensate stored in the deepest part of the drain pan 11 is embedded in the ceiling through the drain port 14 (see FIG. 2) by the operation of the drain pump 12. Drained to the outside of the shape air conditioner 1. Further, a drain port 13 for draining water is provided at the end of the deepest portion of the drain pan 11 and is normally closed with a rubber plug or the like.
　図２は、本発明の実施の形態１に係る天井埋込形空気調和装置の吸込口側から見た概略透視図である。図２に示されるように、本体ケース１ａの内部はファンプレート１７によって送風機部１９と熱交換器部２０とに区画されている。格子状部材３（図１参照）及び天井埋込形空気調和装置１の底面にあるエアフィルタ７（図１参照）を取り外すと、天井埋込形空気調和装置１の送風機部１９の内部を確認することができる。 FIG. 2 is a schematic perspective view seen from the inlet side of the ceiling-embedded air conditioner according to Embodiment 1 of the present invention. As shown in FIG. 2, the inside of the main body case 1 a is partitioned into a blower unit 19 and a heat exchanger unit 20 by a fan plate 17. When the grid member 3 (see FIG. 1) and the air filter 7 (see FIG. 1) on the bottom surface of the ceiling-embedded air conditioner 1 are removed, the inside of the blower unit 19 of the ceiling-embedded air conditioner 1 is confirmed. can do.
　送風機部１９内には２つのファンケース８、電動機１５及び後述するカバー１６が設けられている。なお、電動機１５の軸など、本実施の形態１の説明に不要な部材等の記載は便宜上、省略する。ファンプレート１７は、天井埋込形空気調和装置１の強度を増すための部材としての役割を果たすことに加えて、負圧となる送風機部１９と正圧となる熱交換器部２０とを仕切る役割を果たす。ファンプレート１７には、ファンケース８からの吹き出し空気を通すためのファン開口部２１を設ける必要があり、そのため、ファンプレート１７には、ファンケース８からの吹き出し空気を通すためのファン開口部２１として必要な開口面積よりも大きいファンプレート開口部１８が形成されている。送風機部１９及び熱交換器部２０は、ファンプレート開口部１８を介して連通している。なお、本実施の形態１では、２つのファンケース８を設けた例を示したが、本発明はこれに限定されず、ファンケースを１つ設けても、又は３つ以上設けてもよい。このことは、後述する実施の形態２～４についても同様である。 In the blower section 19, two fan cases 8, an electric motor 15, and a cover 16 described later are provided. It should be noted that description of members unnecessary for the description of the first embodiment, such as the shaft of the electric motor 15, is omitted for the sake of convenience. In addition to serving as a member for increasing the strength of the ceiling-embedded air conditioner 1, the fan plate 17 partitions the blower portion 19 that is negative pressure and the heat exchanger portion 20 that is positive pressure. Play a role. The fan plate 17 needs to be provided with a fan opening 21 through which the air blown from the fan case 8 passes. For this reason, the fan plate 17 has a fan opening 21 through which the blown air from the fan case 8 passes. As a result, a fan plate opening 18 larger than the necessary opening area is formed. The blower unit 19 and the heat exchanger unit 20 communicate with each other through the fan plate opening 18. In addition, although the example which provided the two fan cases 8 was shown in this Embodiment 1, this invention is not limited to this, You may provide one fan case or three or more. The same applies to Embodiments 2 to 4 described later.
　なお、ファンプレート開口部１８は本発明における「開口部」に相当する。また、ファン開口部２１は本発明における「送風口」に相当する。 The fan plate opening 18 corresponds to the “opening” in the present invention. The fan opening 21 corresponds to a “blower” in the present invention.
　ここで、ファンプレート開口部１８は、ファンケース８からの吹き出し空気を通すためのファン開口部２１よりも面積が大きい。このため、送風機部１９及び熱交換器部２０内の空気が、ファンプレート開口部１８とファン開口部２１との隙間を介して互いに混入してしまう。そこで、上記の隙間を塞いで送風機部１９及び熱交換器部２０を互いに独立な空間とし、空気の混入を防止するために、カバー１６がファンケース８と一体となって形成され、ファンプレート開口部１８を覆うように取り付けられている。 Here, the fan plate opening 18 has a larger area than the fan opening 21 through which the air blown from the fan case 8 passes. For this reason, the air in the blower unit 19 and the heat exchanger unit 20 is mixed with each other through the gap between the fan plate opening 18 and the fan opening 21. Therefore, the cover 16 is formed integrally with the fan case 8 so as to close the gap and make the blower unit 19 and the heat exchanger unit 20 independent from each other and prevent air from entering, and the fan plate opening. It is attached so as to cover the portion 18.
　カバー１６は、送風機部１９側からファンプレート１７に対して着脱可能なネジ（図示省略）等で取り付けられている。これにより、作業者は、格子状部材３（図１参照）及びエアフィルタ７（図１参照）を取り外すことで、後述する空気吸込口５を介して、カバー１６のネジに直接アクセスし、当該ネジを取り外すことでカバー１６をファンプレート１７から取り外すことができる。 The cover 16 is attached with screws (not shown) that can be attached to and detached from the fan plate 17 from the blower unit 19 side. Thereby, the operator can directly access the screw of the cover 16 via the air suction port 5 described later by removing the lattice-like member 3 (see FIG. 1) and the air filter 7 (see FIG. 1). The cover 16 can be removed from the fan plate 17 by removing.
　なお、本実施の形態１において、ファンケース８とカバー１６とが一体となって設けられている例を示したが、本発明はこれに限定されず、ファンケース８とカバー１６とを２つの別部品として構成してもよい。
　また、図１（ａ）、図５（ａ）、図５（ｂ）では、送風機部１９の底面に空気吸込口５が形成された例を示したが、本発明はこれに限定されず、空気吸込口５が図１（ｂ）、図５（ｃ）、図５（ｄ）に示すような天井埋込形空気調和装置１の背面（側面）にある構成としてもよい。 In the first embodiment, the fan case 8 and the cover 16 are integrally provided. However, the present invention is not limited to this, and the fan case 8 and the cover 16 are separated into two pieces. It may be configured as a separate part.
Moreover, in FIG. 1 (a), FIG. 5 (a), FIG.5 (b), although the example in which the air suction inlet 5 was formed in the bottom face of the air blower part 19 was shown, this invention is not limited to this, It is good also as a structure which has the air suction inlet 5 in the back surface (side surface) of the ceiling-embedded air conditioning apparatus 1 as shown in FIG.1 (b), FIG.5 (c), and FIG.5 (d).
　図３は、本発明の実施の形態１に係る天井埋込形空気調和装置の熱交換器の構成図である。図３に示されるように、熱交換器９は、フィン部３０に加えて、絞り装置（図示省略）、冷媒分配器２２ａ、冷媒配管２２ｂ、及び配管温度を検知する温度検知器（図示省略）などの複数の部品が配置されている配管部３１で構成されている。冷媒分配器２２ａは、冷媒を効率よく複数の経路に分配し、冷媒配管２２ｂは内部において冷媒が流通している。熱交換器９の配管部３１は、熱交換器９の風路外であって、天井埋込形空気調和装置１の側面側のドレンパン１１上に設置されている。また、ドレンポンプ１２（図２参照）も同様に、熱交換器９の風路外であって、天井埋込形空気調和装置１の側面側のドレンパン１１上に設置されている。 FIG. 3 is a configuration diagram of the heat exchanger of the ceiling-embedded air conditioner according to Embodiment 1 of the present invention. As shown in FIG. 3, in addition to the fin portion 30, the heat exchanger 9 includes an expansion device (not shown), a refrigerant distributor 22a, a refrigerant pipe 22b, and a temperature detector (not shown) that detects the pipe temperature. It is comprised by the piping part 31 by which several components, such as, are arrange | positioned. The refrigerant distributor 22a efficiently distributes the refrigerant to a plurality of paths, and the refrigerant is circulated in the refrigerant pipe 22b. The piping portion 31 of the heat exchanger 9 is installed on the drain pan 11 on the side surface side of the ceiling-embedded air conditioner 1 outside the air path of the heat exchanger 9. Similarly, the drain pump 12 (see FIG. 2) is installed outside the air passage of the heat exchanger 9 and on the drain pan 11 on the side surface side of the ceiling-embedded air conditioner 1.
　図４は、本発明の実施の形態１に係る天井埋込形空気調和装置の送風機部側から見た概略断面図である。図４に示されるように、ファン開口部２１は、必要風量を確保するために必要な開口面積のみで構成されているため、ファンプレート開口部１８より小さい。また、ファン開口部２１は、可能な限り均等に熱交換器９に空気が行き渡るように、ファン開口部２１の投影面上に熱交換器９が位置するように配置される。 FIG. 4 is a schematic cross-sectional view of the ceiling-embedded air conditioner according to Embodiment 1 of the present invention as viewed from the blower unit side. As shown in FIG. 4, the fan opening 21 is smaller than the fan plate opening 18 because the fan opening 21 is configured with only an opening area necessary for securing the necessary air volume. The fan opening 21 is arranged so that the heat exchanger 9 is positioned on the projection surface of the fan opening 21 so that air is distributed to the heat exchanger 9 as evenly as possible.
　ファンプレート開口部１８の左右方向の位置関係については、ファンプレート開口部１８の投影面が、配管部３１を含みつつ、熱交換器９と重複するように設置されている。また、ファンプレート開口部１８の上下方向の位置関係については、ファンプレート開口部１８の投影面が、ドレンパン１１の上端部及び熱交換器９と重複するように設置されている。このように、ファンプレート１７は、大きなファンプレート開口部１８を有するが、ファンプレート開口部１８を原因とするファンプレート１７の強度の低下を防ぐため、ファンプレート１７には絞り及び曲げ（図示省略）などの補強加工がなされている。 Regarding the positional relationship in the left-right direction of the fan plate opening 18, the projection surface of the fan plate opening 18 is installed so as to overlap the heat exchanger 9 while including the pipe portion 31. Further, regarding the vertical positional relationship of the fan plate opening 18, the projection surface of the fan plate opening 18 is installed so as to overlap the upper end of the drain pan 11 and the heat exchanger 9. As described above, the fan plate 17 has the large fan plate opening 18, but in order to prevent the strength of the fan plate 17 from being reduced due to the fan plate opening 18, the fan plate 17 is restricted and bent (not shown). ) Etc. are reinforced.

That is, the drain pan 11 only needs to be able to move a distance equal to or longer than the reference length d from the fan plate 17 side of the heat exchanger section 20 to the air outlet 53 side.
［実施の形態３の効果］
　以上のことから、天井埋込形空気調和装置１は、熱交換器９で発生した凝縮水を貯留し、底部に傾斜を有するドレンパン１１と熱交換器部２０の底面に設けられ、ドレンパン１１を載置する底板４０と、を更に備える構成とした。そして、天井埋込形空気調和装置１の底板４０は、熱交換器部２０に回動自在に設けられ、熱交換器部２０は、ファンプレート１７と対向する側面に空気を吹き出す空気吹出口５３を有し、空気吹出口５３を有する面とドレンパン１１との間にクッション材４３を備える構成とした。 [Effect of Embodiment 3]
