Description

本発明は、天井裏に取付けられるビルトインタイプであり、たとえばダクトを介して天井板に設けられる吹出し口と連通する室内機である空気調和装置に関する。   The present invention relates to an air conditioner that is a built-in type that is attached to the back of a ceiling, and is an indoor unit that communicates with, for example, a blowout opening provided in a ceiling plate via a duct.

店舗などの広い空間を空調する場合には、空気調和装置の室内機として壁面に取付けられる、いわゆる壁掛け形よりも、天井裏に取付けられるビルトインタイプのものの方が有利である。すなわち、この種の室内機は、天井板に設けられる複数の吹出し口とダクトを介して連通されるので、室内全体に均一に熱交換空気を吹出すことができ、快適空調が得られるとともに、壁掛け形のように居住者が受ける圧迫感がない。
この種のビルトインタイプ室内機の内部構造は、本体内を仕切り板で２室に仕切り、一方室に送風機が配置され、他方室に熱交換器と、この熱交換器を載置するドレンパンが配置される。送風機の配置室下面には吸込み口が設けられ、熱交換器等の配置室側面には吹出し口が設けられて、いずれもダクトを介して室内の天井板に設けられる開口部に接続される。 When air-conditioning a wide space such as a store, a built-in type that is attached to the back of the ceiling is more advantageous than a so-called wall-mounted type that is attached to a wall surface as an indoor unit of an air conditioner. That is, this type of indoor unit communicates with a plurality of outlets provided in the ceiling plate via a duct, so that heat exchange air can be blown uniformly throughout the room, and comfortable air conditioning can be obtained. There is no feeling of oppression that the residents receive like the wall-mounted type.
The internal structure of this type of built-in type indoor unit is divided into two chambers with a partition plate inside the main body, a blower is placed in one chamber, a heat exchanger and a drain pan on which this heat exchanger is placed are placed in the other chamber Is done. A suction port is provided on the lower surface of the arrangement chamber of the blower, and an outlet port is provided on the side surface of the arrangement chamber of the heat exchanger or the like, both of which are connected to an opening provided on an indoor ceiling plate via a duct.

冷凍サイクル運転をなすとともに送風機を駆動することにより、吸込み口から吸込まれた室内空気が仕切り板に設けられた連通口を介して熱交換器に導かれ、ここで冷媒と室内空気とが熱交換する。熱交換した空気は吹出し口からダクトを介して室内へ吹出され、室内の空気調和をなす。また、熱交換器における熱交換作用にともなって室内空気に含まれる水分が凝縮され、ドレン水が生成されてドレンパンに滴下する。
上記ドレンパンに対する清掃、保守、点検のために、所定期間毎にメンテナンス作業が必要である。室内機が天井裏のような室内高所に取付けられているので、ドレンパンをより容易に本体から取外し自在な構造としなければならない。［特許文献１］には、天井板から室内に露出する化粧カバーを兼ねた露受皿を、取付けねじを介して本体に取付け固定する構造の天井埋込型空気調和機が開示されている。
特開２００１−２４８８５７号公報 By performing the refrigeration cycle operation and driving the blower, the indoor air sucked from the suction port is led to the heat exchanger through the communication port provided in the partition plate, where the refrigerant and the indoor air exchange heat. To do. The heat-exchanged air is blown into the room through the duct from the blow-out port, and the air in the room is harmonized. Moreover, the water | moisture content contained in indoor air is condensed with the heat exchange effect | action in a heat exchanger, drain water is produced | generated, and it is dripped at a drain pan.
In order to clean, maintain, and inspect the drain pan, maintenance work is required every predetermined period. Since the indoor unit is attached to an indoor high place such as the back of the ceiling, the drain pan must be structured so that it can be easily detached from the main body. [Patent Document 1] discloses a ceiling-embedded air conditioner having a structure in which a dew tray serving also as a decorative cover exposed from a ceiling board to a room is attached and fixed to a main body via a mounting screw.
JP 2001-248857 A

上述の［特許文献１］の技術では、下方から取付けねじを外すことができて、室内高所での作業性が考慮されている。しかしながら、ここでの空気調和機は、ドレンパンと化粧カバーが一体化されている。化粧カバーが板金加工物であるとすると、板金加工が複雑になってコストに影響を与えてしまう。
たとえ、化粧カバーを合成樹脂材から成形したとしても、ドレンパンとの一体構造物であるので重量が嵩むことは避けられない。作業者は一方の手に工具を持って取付けねじを取外し、その間、他方の手で化粧カバーとドレンパンの一体構造物を押上げて落下を防止しなければならず、作業性が極めて悪いものである。 In the technique of the above-mentioned [Patent Document 1], a mounting screw can be removed from below, and workability in an indoor high place is taken into consideration. However, in the air conditioner here, the drain pan and the decorative cover are integrated. If the decorative cover is a sheet metal processed product, the sheet metal processing becomes complicated and the cost is affected.
Even if the decorative cover is molded from a synthetic resin material, it is inevitable that the weight is increased because it is an integral structure with the drain pan. The operator must hold the tool in one hand and remove the mounting screw. Meanwhile, the other hand must push up the integrated structure of the decorative cover and the drain pan to prevent it from falling. is there.

特に［特許文献１］には記載されていないが、一般的にはドレンパンは単純に平面視で略矩形の皿状に形成されるだけのものであって、ドレン水を集溜する内底部の深さ寸法は全面的に均一寸法となっている。ドレンパンを本体から取外しする際は、ドレンパンの一側端部を本体に残した状態で他側端部を本体から引き下ろし、ドレンパンを一旦、斜め姿勢にしてから、ドレンパン全体を本体から取外しする。
ドレンパンにはドレンホースが接続されていて、ドレン水を外部に排出するようになっているが、それでもなお一部のドレン水は排出し切れずにドレンパンに残っていることが多い。ドレンパンの本体からの取外しの際は、ドレンパンを斜め姿勢とするところから、残っていたドレン水が傾斜下側に溜り、残量によってはこの端部から溢出する虞れが大である。溢出するドレン水は作業者自身を直撃し、もしくは被空調室の床面や調度品を濡らしてしまう。 Although not specifically described in [Patent Document 1], in general, the drain pan is simply formed in a substantially rectangular dish shape in a plan view, and the inner bottom portion for collecting drain water is used. The depth dimension is uniform throughout. When removing the drain pan from the main body, the other side end is pulled down from the main body while leaving one side end of the drain pan on the main body, the drain pan is once inclined, and then the entire drain pan is removed from the main body.
A drain hose is connected to the drain pan, and drain water is discharged to the outside. However, some drain water still remains in the drain pan without being completely discharged. When removing the drain pan from the main body, the drain pan is left in a slanted posture, so that the remaining drain water accumulates on the lower side of the slope, and depending on the remaining amount, there is a high risk of overflowing from this end. The overflowing drain water hits the operator himself or wets the floor and furniture of the air-conditioned room.

本発明は、上記事情に着目してなされたものであり、その目的とするところは、ドレンパンの底部下面に把持手段を備えることにより、ドレンパンの保守、点検、清掃等のメンテナンス作業時におけるドレンパンの取付けと取外しを容易化して、作業性の向上化を図れる空気調和装置を提供しようとするものである。   The present invention has been made paying attention to the above circumstances, and the purpose of the present invention is to provide gripping means on the lower surface of the bottom of the drain pan so that the drain pan can be maintained during maintenance work such as maintenance, inspection, and cleaning of the drain pan. An object of the present invention is to provide an air conditioner that can be easily attached and detached to improve workability.

上記課題を解決し目的を達成するために本発明の空気調和装置は、吸込み口および吹出し口を備えた本体と、この本体内に収容され駆動にともなって吸込み口から本体内に熱交換空気を吸込んで吹出し口から吹出す熱交換空気導通路を形成する送風機と、交換空気導通路に位置する熱交換器および熱交換器の下部に設けられ熱交換器を載置するドレンパンとを具備し、上記ドレンパンは、底部下面に把持手段が設けられる。   In order to solve the above-described problems and achieve the object, an air conditioner of the present invention includes a main body having a suction port and a blow-off port, and heat exchange air accommodated in the main body and driven from the suction port into the main body as it is driven. A blower that forms a heat exchange air conduction path that sucks in and blows out from the outlet, a heat exchanger that is located in the exchange air conduction path, and a drain pan that is provided at the bottom of the heat exchanger and places the heat exchanger, The drain pan is provided with a gripping means on the bottom lower surface.

本発明によれば、ドレンパンの保守、点検、清掃等のメンテナンス作業性の向上化を図れる等の効果を奏する。   According to the present invention, it is possible to improve the maintenance workability such as maintenance, inspection, and cleaning of the drain pan.

以下、本発明の実施の形態を図面にもとづいて説明する。
図１は本発明の一実施の形態に係るビルトインタイプの空気調和装置における室内機の取付け状態を説明する図、図２は室内機の概略の断面図、図３は室内機の一部を分解して示す斜視図、図４はさらに室内機の一部を分解して示す斜視図、図５はドレンパンの底部下面の斜視図である。
筐体である本体１は、長手方向Ｘの寸法が、長手方向Ｘとは直交する方向である、幅方向Ｙと比較して短い薄型矩形箱状に成形されていて、各面部全てが、金属薄板を板金加工してなる。
本体１の両側面には一対ずつの取付け具２が設けられていて、これら取付け具２のそれぞれには天井裏Ｔに設けられる梁材３から垂設される吊持杆４が挿入され、かつ取付け固定される。すなわち本体１は、梁材３と天井板５との間である、天井裏Ｔに設けられることになる。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram for explaining an installation state of an indoor unit in a built-in type air conditioner according to an embodiment of the present invention, FIG. 2 is a schematic sectional view of the indoor unit, and FIG. 3 is an exploded view of a part of the indoor unit. 4 is an exploded perspective view of a part of the indoor unit, and FIG. 5 is a perspective view of the bottom surface of the bottom of the drain pan.
The main body 1 which is a housing is formed in a thin rectangular box shape whose dimensions in the longitudinal direction X are shorter than the width direction Y, which is a direction perpendicular to the longitudinal direction X, and all the surface portions are made of metal. Sheet metal is processed from sheet metal.
A pair of attachments 2 are provided on both side surfaces of the main body 1, and a suspension rod 4 suspended from a beam member 3 provided on the ceiling back T is inserted into each of the attachments 2, and Installation fixed. That is, the main body 1 is provided on the ceiling back T between the beam member 3 and the ceiling plate 5.

本体１内の長手方向Ｘにおける略半分の長さ位置には、仕切り板６が本体１の幅方向Ｙに亘って設けられる。本体１内部は仕切り板６によって２室７Ａ，７Ｂに区分されていて、一方室を機械室７Ａと呼び、送風機８が配置される。他方室を熱交換室７Ｂと呼び、熱交換器９およびドレンパン１０が配置される。
上記機械室７Ａの下面に吸込み口１１が開口され、上記熱交換室７Ｂの側面には吹出し口１２が開口される。上記本体１が天井裏Ｔに取付け固定された状態で、上記吸込み口１１には吸込みダクト１３が接続され、上記吹出し口１２には複数の吹出しダクト１４が接続される。 A partition plate 6 is provided across the width direction Y of the main body 1 at approximately half the length position in the longitudinal direction X within the main body 1. The inside of the main body 1 is divided into two chambers 7A and 7B by a partition plate 6. One chamber is called a machine chamber 7A, and a blower 8 is arranged. The other chamber is called a heat exchange chamber 7B, and a heat exchanger 9 and a drain pan 10 are arranged.
A suction port 11 is opened on the lower surface of the machine room 7A, and a blowout port 12 is opened on a side surface of the heat exchange chamber 7B. In a state where the main body 1 is attached and fixed to the ceiling T, a suction duct 13 is connected to the suction port 11, and a plurality of outlet ducts 14 are connected to the outlet 12.

上記吸込みダクト１３は、天井板５に開口する取付け用口１５に取付けられた化粧グリル１６に接続される。梁材３と天井板５との間の寸法によっては、本体１に設けられる吸込み口１１が直接、天井板５の取付け用口１５に対向する場合がある。このときは、当然、吸込みダクト１３を省略して化粧グリル１６を取付け用口１５に取付ける。
上記吹出しダクト１４は、普通、天井板５に設けられる図示しない複数の室内吹出し口に連通される。すなわち、本体１から導出される熱交換空気は吹出しダクト１４で分流され、複数の室内吹出し口から一斉に室内へ吹出されて、室内の部位に係わらず均一な空調を行えるようになっている。 The suction duct 13 is connected to a decorative grill 16 attached to an attachment port 15 that opens to the ceiling plate 5. Depending on the dimension between the beam member 3 and the ceiling plate 5, the suction port 11 provided in the main body 1 may directly face the mounting port 15 of the ceiling plate 5. In this case, naturally, the suction duct 13 is omitted and the decorative grill 16 is attached to the attachment port 15.
The blowout duct 14 is usually communicated with a plurality of indoor blowout openings (not shown) provided on the ceiling board 5. In other words, the heat exchange air led out from the main body 1 is diverted by the blowout duct 14 and blown into the room from a plurality of indoor blowout openings at the same time so that uniform air conditioning can be performed regardless of the indoor part.

上記機械室７Ａに配置される送風機８は、中央部に図示しない二軸のファンモータを備えている。各回転軸には、回転にともなって軸方向から空気を吸込んで周方向へ吹出すタイプのファン（いわゆる多翼型ファン）１７が連結され、さらに各ファン１７はファンケーシング１８で囲撓される。
上記ファンケーシング１８の仕切り板６側端部に吹出し口体部１８ａが形成され、仕切り板６に開口される連通口１９に吹出し口体部１８ａが接続される。したがって、連通口１９は、送風機８のファン１７を駆動するのにともなって、ファンケーシング１８の吹出し口体部１８ａから吹出される風を直接、上記熱交換室７Ｂ側へ送風案内できる。 The blower 8 disposed in the machine room 7A includes a biaxial fan motor (not shown) at the center. Each rotary shaft is connected to a fan (so-called multi-blade fan) 17 of a type that sucks air from the axial direction and blows it out in the circumferential direction as it rotates, and each fan 17 is surrounded by a fan casing 18. .
A blowout port body 18 a is formed at the end of the fan casing 18 on the partition plate 6 side, and the blowout port body 18 a is connected to the communication port 19 opened in the partition plate 6. Accordingly, the communication port 19 can guide the air blown from the outlet body 18a of the fan casing 18 directly to the heat exchange chamber 7B as the fan 17 of the blower 8 is driven.

上記熱交換室７Ｂに配置される熱交換器９は、両側端部に図示しない端板が配置され、これら端板間に複数枚のアルミフィン９ａが所定の間隙を存して並設され、両端板およびアルミフィン９ａに複数本の伝熱管９ｂが貫通されてなるフィンチューブ型である。この熱交換器９は、ドレンパン１０上に、上下方向が斜めに傾斜した姿勢で載置され、両端板が図示しない固定板を介して本体１に固定される。
すなわち、本体１が天井裏Ｔに取付けられるので、本体１を可能な限り薄型化する必要から、熱交換器９の上下方向寸法を充分な長さに設定することができない。その一方で、熱交換器９の熱交換面積を可能な限り確保して、熱交換効率の向上を図らなければならない。したがって、熱交換器９を傾斜姿勢とすることで、上下方向寸法を抑えて薄型の本体１内に収容可能となし、かつ充分な熱交換面積を確保できる。 The heat exchanger 9 arranged in the heat exchange chamber 7B has end plates (not shown) arranged on both side ends, and a plurality of aluminum fins 9a are arranged in parallel with a predetermined gap between these end plates, It is a fin tube type in which a plurality of heat transfer tubes 9b are penetrated by both end plates and aluminum fins 9a. The heat exchanger 9 is placed on the drain pan 10 in a posture in which the vertical direction is inclined obliquely, and both end plates are fixed to the main body 1 via a fixing plate (not shown).
That is, since the main body 1 is attached to the ceiling T, the vertical dimension of the heat exchanger 9 cannot be set to a sufficient length because it is necessary to make the main body 1 as thin as possible. On the other hand, it is necessary to secure the heat exchange area of the heat exchanger 9 as much as possible to improve the heat exchange efficiency. Therefore, by setting the heat exchanger 9 to the inclined posture, the vertical dimension can be suppressed and the heat exchanger 9 can be accommodated in the thin main body 1, and a sufficient heat exchange area can be secured.

上記熱交換室７Ｂを構成する本体１の内側表面は、アクリロニトリル・ブタジエン・スチレン樹脂（ＡＢＳ樹脂）等の合成樹脂材でコーティングされている。さらに、熱交換室７Ｂの長手方向Ｘに沿う両側板内面は、吹出し口１２側端部から仕切り板６に亘って全面的に断熱材Ｄが貼着される。
断熱材Ｄの下端面と上記ドレンパン１０の左右側壁部１０ｃ，１０ｄの上端面とは、シール部材Ｓを介して接している。このシール部材Ｓは、ＥＰＤＭ（エチレン・プロピレン・ジエンゴム）等の合成樹脂材からなり、扁平の紐状体をなしていて、ドレンパン１０の底部１０ｅ下面における周縁と中間部および側壁部１０ａ〜１０ｄの周縁等に貼着されている。 The inner surface of the main body 1 constituting the heat exchange chamber 7B is coated with a synthetic resin material such as acrylonitrile / butadiene / styrene resin (ABS resin). Furthermore, the heat insulating material D is entirely attached to the inner surfaces of both side plates along the longitudinal direction X of the heat exchange chamber 7B from the outlet 12 side end portion to the partition plate 6.
The lower end surface of the heat insulating material D and the upper end surfaces of the left and right side wall portions 10c, 10d of the drain pan 10 are in contact with each other through a seal member S. The seal member S is made of a synthetic resin material such as EPDM (ethylene / propylene / diene rubber), has a flat string-like body, and includes a peripheral edge, an intermediate portion, and side wall portions 10a to 10d on the bottom surface of the bottom portion 10e of the drain pan 10. It is stuck on the periphery.

上記ドレンパン１０は、たとえば発泡スチロールなどの発泡性合成樹脂材を発泡して得られる略矩形皿状の成型品であって、底部１０ｅ内面はＡＢＳ樹脂等の合成樹脂材でコーティングされている。
ドレンパン１０の長手方向Ｘと幅方向Ｙの寸法が、熱交換室７Ｂの長手方向Ｘと幅方向Ｙの寸法と略同一に形成されている。後述するように、本体１に備えたドレンパン支持構造体Ｋを介してドレンパン１０を熱交換室７Ｂに取付けた状態で、ドレンパン１０は熱交換室７Ｂの全面に亘って、ほとんど隙間のない状態で嵌め込まれる。
ドレンパン１０における吹出し口１２側の側壁部１０ａは、断熱材Ｄ下面と、本体１の下面角部を構成するフレーム１ａとにより挟まれて支持される。特に、この側壁部１０ａの外底面隅部ａは斜めに形成されていて、ドレンパン１０の本体１への取付けと取外しが容易になるように構成される。 The drain pan 10 is a substantially rectangular dish-shaped molded product obtained by foaming a foamable synthetic resin material such as styrene foam, and the inner surface of the bottom 10e is coated with a synthetic resin material such as ABS resin.
The dimensions of the drain pan 10 in the longitudinal direction X and the width direction Y are substantially the same as the dimensions of the heat exchange chamber 7B in the longitudinal direction X and the width direction Y. As will be described later, with the drain pan 10 attached to the heat exchange chamber 7B via the drain pan support structure K provided in the main body 1, the drain pan 10 has almost no gap over the entire surface of the heat exchange chamber 7B. It is inserted.
The side wall 10 a on the outlet 12 side of the drain pan 10 is supported by being sandwiched between the lower surface of the heat insulating material D and the frame 1 a constituting the lower surface corner of the main body 1. In particular, the outer bottom corner portion a of the side wall portion 10a is formed obliquely so that the drain pan 10 can be easily attached to and removed from the main body 1.

上記ドレンパン１０の底部１０ｅ内面には、載置部２０と、この載置部２０を挟んだ両側に１次側ドレン受け部２１と２次側ドレン受け部２２が形成される。載置部２０上面に沿って、ある程度の高さ寸法を有する直状の突堤となるクッション材ｄが取付けられ、熱交換器９に対する機械的な負担を軽減した状態で熱交換器９を載置できる。
上記載置部２０を挟んで後述する熱交換空気導通路Ｒの風上側に上記１次側ドレン受け部２１が設けられ、熱交換空気導通路Ｒの風下側に上記２次側ドレン受け部２２が設けられる。上記熱交換器９は、載置部２０から２次側ドレン受け部２２側に斜めに傾斜していて、下部側の一部が１次側ドレン受け部２１側へ突出している。 On the inner surface of the bottom 10 e of the drain pan 10, a placement portion 20 and a primary drain receiving portion 21 and a secondary drain receiving portion 22 are formed on both sides of the placement portion 20. A cushion material d, which is a straight jetty having a certain height, is attached along the upper surface of the mounting portion 20, and the heat exchanger 9 is mounted in a state where the mechanical burden on the heat exchanger 9 is reduced. it can.
The primary drain receiving part 21 is provided on the windward side of the heat exchange air conduction path R, which will be described later, with the placement part 20 interposed therebetween, and the secondary drain receiving part 22 is provided on the leeward side of the heat exchange air conduction path R. Is provided. The heat exchanger 9 is inclined obliquely from the mounting portion 20 to the secondary drain receiving portion 22 side, and a part of the lower side protrudes toward the primary drain receiving portion 21 side.

上記載置部２０は、幅方向Ｙに沿う側壁部１０ｂと所定間隔を存して並行に設けられ、熱交換器９の下端鈍角部を載置するのに必要最小限の幅に形成される。載置部２０の両側端部は、長手方向Ｘに沿う側壁部１０ｃ，１０ｄと狭小の間隙を存している。
１次側ドレン受け部２１の深さ寸法は、２次側ドレン受け部２２の深さ寸法よりも深く形成されている。そして、２次側ドレン受け部２２は、載置部２０側が最も深く、載置部２０と長手方向Ｘに対向して設けられる側壁部１０ａに向かって漸次浅くなる傾斜に形成される。 The placement portion 20 is provided in parallel with the side wall portion 10b along the width direction Y at a predetermined interval, and is formed to have a minimum width necessary for placing the lower end obtuse angle portion of the heat exchanger 9. . Both side end portions of the mounting portion 20 have narrow gaps with the side wall portions 10c and 10d along the longitudinal direction X.
The depth dimension of the primary side drain receiving part 21 is formed deeper than the depth dimension of the secondary side drain receiving part 22. The secondary-side drain receiving portion 22 is formed with an inclination that is deepest on the placement portion 20 side and gradually becomes shallower toward the side wall portion 10a provided facing the placement portion 20 in the longitudinal direction X.

このような２次側ドレン受け部２２における幅方向Ｙの両側部に沿って凸部２５が突設される。凸部２５の両側端部は傾斜面となっていて、載置部２０の両側端部と所定の間隙を存して対向している。この側端部にクッション材ｄが貼着され、クッション材ｄを介して凸部２５の傾斜面に熱交換器９が当接する。
２次側ドレン受け部２２と１次側ドレン受け部２１の一側部は、凸部２５の側端部と、載置部２０の端部との間に形成される隙間を介して連通しており、この隙間をドレン流通路２７と呼ぶ。上記熱交換器９を載置部２０上に載置した状態で、熱交換器９が凸部２５の側端部上に当接するので、ドレン流通路２７の上方空間が熱交換器９で塞がれてトンネル状となる。 Convex portions 25 project from both side portions in the width direction Y of the secondary side drain receiving portion 22. Both end portions of the convex portion 25 are inclined surfaces and face both end portions of the mounting portion 20 with a predetermined gap. The cushion material d is adhered to the side end portion, and the heat exchanger 9 comes into contact with the inclined surface of the convex portion 25 through the cushion material d.
One side portion of the secondary drain receiving portion 22 and the primary side drain receiving portion 21 communicate with each other via a gap formed between the side end portion of the convex portion 25 and the end portion of the mounting portion 20. This gap is called the drain flow passage 27. In a state where the heat exchanger 9 is placed on the placement portion 20, the heat exchanger 9 abuts on the side end portion of the convex portion 25, so that the space above the drain flow passage 27 is blocked by the heat exchanger 9. It comes off and becomes a tunnel shape.

ドレン流通路２７の近傍で、１次側ドレン受け部２１の幅方向Ｙと対向する側壁部１０ｃ，１０ｄに排水口２９が設けられていて、図示しないドレンホースを接続するための接続用口体３０が外方へ突設される。１次側ドレン受け部２１に溜るドレン水は、左右の排水口２９から接続用口体３０とドレンホースを介して排出されるようになっている。
実際には、本体１を天井裏Ｔの所定の部位に取付けたあと、テストとして１次側ドレン受け部２１に水を落し、ドレンホースを接続する側に水が流れるように本体１の取付け姿勢を調整する。場合によっては、水がより多く流れる側の接続用口体３０にドレンホースを接続し、少ない側の接続用口体３０は栓体で塞ぐ。 A drain port 29 is provided in the side wall portions 10c, 10d facing the width direction Y of the primary drain receiving portion 21 in the vicinity of the drain flow passage 27, and a connection mouth for connecting a drain hose (not shown). 30 protrudes outward. The drain water collected in the primary side drain receiving part 21 is discharged | emitted via the connection port body 30 and a drain hose from the drainage port 29 on either side.
Actually, after the main body 1 is attached to a predetermined part of the ceiling T, the main body 1 is mounted in such a manner that water is dropped on the primary drain receiving portion 21 as a test and the water flows to the side where the drain hose is connected. Adjust. In some cases, a drain hose is connected to the connection port 30 on the side where more water flows, and the connection port 30 on the smaller side is closed with a plug.

さらにドレンパン１０の底部１０ｅ下面において、中間桟部ｅから幅方向Ｙに所定間隔を存した両側で、かつ並行桟部ｆ相互に亘って、把持手段をなす一対の把手部２６が設けられる。これら把手部２６は、作業者が左右それぞれの手で摘み易い幅寸法と深さ寸法に設定されている。
把手部２６と中間桟部ｅおよび一対の並行桟部ｆとによって囲まれる底部１０ｅ下面には、「ドレンパンの取外しの際はこの把手をつかんでください」旨の注意書き２８ａと、把手２６を指す矢印２８ｂが記されている。
なお、上記本体１の下面は、機械室７Ａに設けられる吸込み口１１以外の部分が第１の下面板１Ａによって覆われ、熱交換室７Ｂ全体の下面は第２の下面板１Ｂによって覆われる。これら第１、第２の下面板１Ａ，１Ｂは取付けねじを介して本体１に着脱自在に取付けられる。 On the bottom surface of the bottom portion 10e of the drain pan 10, an intermediate beam portion e is provided at the intermediate portion in the width direction Y to which the sealing member S is adhered in the longitudinal direction X, and from the side wall portion 10c via the intermediate beam portion e. A pair of crosspieces f are provided in parallel in the longitudinal direction X at a predetermined interval up to a position near the other side wall 10d.
Further, on the bottom surface of the bottom portion 10e of the drain pan 10, a pair of grip portions 26 that constitute gripping means are provided on both sides of the intermediate rail portion e at a predetermined interval in the width direction Y and across the parallel rail portions f. These grip portions 26 are set to a width dimension and a depth dimension that are easy for an operator to pick with the left and right hands.
On the bottom surface of the bottom portion 10e surrounded by the handle portion 26, the intermediate crosspiece portion e, and the pair of parallel crosspiece portions f, a caution 28a indicating "Please hold this handle when removing the drain pan" and the handle 26 are indicated. An arrow 28b is marked.
The lower surface of the main body 1 is covered with the first lower surface plate 1A except for the suction port 11 provided in the machine chamber 7A, and the entire lower surface of the heat exchange chamber 7B is covered with the second lower surface plate 1B. These first and second lower surface plates 1A and 1B are detachably attached to the main body 1 via attachment screws.

第２の下面板１Ｂにおいては熱交換室７Ｂ全体を覆うところから、熱交換室７Ｂに取付けられるドレンパン１０の底部１０ｅ下面を開閉自在に覆うことになる。第２の下面板１Ｂを取外せば、ドレンパン１０の底部１０ｅ下面が露出し、底部１０ｅ下面に設けられる一対の把手部２６が露出する。
上記ドレンパン支持構造体Ｋは、ドレンパン１０の２次側ドレン受け部２２風下側端部である吹出し口１２側の側壁部１０ａを掛合支持するフレーム１ａと断熱材Ｄ下端面との間の部位と、ドレンパン１０の両側壁部１０ｃ，１０ｄを密に嵌め込む寸法形状の本体１側面部および、ドレンパン１０の１次側ドレン受け部２１風下側端部である仕切り板６側の側壁部１０ｂを密に嵌め込む寸法形状から構成される。 In the 2nd lower surface board 1B, from the place which covers the whole heat exchange chamber 7B, the bottom part 10e lower surface of the drain pan 10 attached to the heat exchange chamber 7B is covered so that opening and closing is possible. When the second lower surface plate 1B is removed, the lower surface of the bottom portion 10e of the drain pan 10 is exposed, and the pair of grip portions 26 provided on the lower surface of the bottom portion 10e are exposed.
The drain pan support structure K includes a portion between the frame 1a that engages and supports the side wall portion 10a on the outlet 12 side that is the downstream side drain receiving portion 22 of the drain pan 10 and the lower end surface of the heat insulating material D. The side wall 10c and 10d of both sides of the drain pan 10 are closely fitted, and the side wall 10b on the side of the partition plate 6 that is the leeward side end of the primary drain receiving portion 21 of the drain pan 10 It is comprised from the dimension shape fitted in.

このように構成される空気調和装置の室内機であり、冷凍サイクル運転とともに送風機８が駆動されると、室内空気が化粧グリル１６と吸込み口１１を介して本体１内に吸込まれ、熱交換空気導通路Ｒに沿って導かれる。具体的には、熱交換空気は吸込み口１１から機械室７Ａに吸込まれ、送風機８を構成するファンケーシング１８と、仕切り板６に設けられる連通口１９を介して熱交換室７Ｂに導かれる。
熱交換空気は、ドレンパン１０に載置されている熱交換器９に向かって吹出され、流通して熱交換器９に導かれる冷媒と熱交換される。熱交換器９と熱交換したあとの熱交換空気は、吹出し口１２に導かれダクト１４を介して室内へ吹出されて、室内の空調作用をなす。 When the blower 8 is driven together with the refrigeration cycle operation, the indoor air of the air conditioner configured as described above is sucked into the main body 1 through the decorative grille 16 and the suction port 11, and heat exchange air. It is guided along the conduction path R. Specifically, the heat exchange air is sucked into the machine room 7 </ b> A from the suction port 11, and is guided to the heat exchange chamber 7 </ b> B through the fan casing 18 constituting the blower 8 and the communication port 19 provided in the partition plate 6.
The heat exchange air is blown toward the heat exchanger 9 placed on the drain pan 10, and is heat exchanged with the refrigerant that is circulated and led to the heat exchanger 9. The heat exchange air after heat exchange with the heat exchanger 9 is led to the blowout port 12 and blown out into the room through the duct 14 to perform an air conditioning operation in the room.

冷房運転時には、熱交換器９の熱交換作用にともなってドレン水が生成され、ドレンパン１０に滴下する。ドレンパン１０に載置される熱交換器９の形態および配置状態から、風量が大きかったりドレン水の発生量が多いと、１次側ドレン受け部２１に滴下するドレン水よりも２次側ドレン受け部２２に滴下するドレン水の量が多くなる。
２次側ドレン受け部２２に滴下したドレン水は載置部２０方向へ向かって流れ、この載置部２０で一旦、せき止められてから、載置部２０の左右両側端のドレン流通路２７を介して１次側ドレン受け部２１に流入する。１次側ドレン受け部２１に集溜されたドレン水は、排水口２９とドレンホースを介して外部へ排出される。 During the cooling operation, drain water is generated along with the heat exchange action of the heat exchanger 9 and dripped onto the drain pan 10. From the form and arrangement state of the heat exchanger 9 placed on the drain pan 10, when the air volume is large or the amount of drain water generated is large, the secondary drain receiver is received more than the drain water dripped onto the primary drain receiver 21. The amount of drain water dripped onto the portion 22 increases.
The drain water dropped on the secondary drain receiving portion 22 flows toward the placement portion 20, and once drained by the placement portion 20, the drain water passes through the drain flow passages 27 on both left and right ends of the placement portion 20. And flows into the primary-side drain receiving part 21. The drain water collected in the primary side drain receiving portion 21 is discharged to the outside through the drain port 29 and the drain hose.

上記ドレンパン１０の清掃、保守、点検等のメンテナンス作業を行う際は、ドレンパン１０の底部１０ｅ内面が対象となるので、ドレンパン１０を本体１のドレンパン支持構造体Ｋから取外して、床面に置く必要がある。このときは、少なくとも本体１を構成する第２の下面板１Ｂと対向する天井板５部位を取外し、さらに第２の下面板１Ｂを取外してドレンパン１０の底部１０ｅ下面を露出する。
したがって、ドレンパン１０の底部１０ｅ下面に設けられる両方の把手部２６が露出する。作業者は、左右の把手部２６を持ってドレンパン１０を引き下ろすのだが、上記ドレンパン支持構造体Ｋは、ドレンパン１０を吹出し口１２側端部から先に引き下ろすことと、吹出し口１２側端部と仕切り板６側端部とを平衡した状態で引き下ろすことを規制している。 When performing maintenance work such as cleaning, maintenance, and inspection of the drain pan 10, the inner surface of the bottom 10 e of the drain pan 10 is an object. Therefore, it is necessary to remove the drain pan 10 from the drain pan support structure K of the main body 1 and place it on the floor surface. There is. At this time, at least the portion of the ceiling plate 5 facing the second lower surface plate 1B constituting the main body 1 is removed, and the second lower surface plate 1B is further removed to expose the lower surface of the bottom portion 10e of the drain pan 10.
Therefore, both the grip portions 26 provided on the bottom surface of the bottom portion 10e of the drain pan 10 are exposed. The operator pulls down the drain pan 10 while holding the left and right handle portions 26, and the drain pan support structure K pulls down the drain pan 10 first from the end on the outlet 12 side and the end on the outlet 12 side. Pulling down in a state in which the part and the end of the partition plate 6 are balanced.

すなわちドレンパン支持構造体Ｋは、ドレンパン１０の吹出し口１２側端部（側壁部１０ａ）を本体１下角部のフレーム１ａと断熱材Ｄ下端面との間に掛合する一方で、他の側壁部１０ｂ〜１０ｄを熱交換室７Ｂを構成する本体１側面部と仕切り板６間に密に嵌め込んで、本体１にドレンパン１０を支持している。そのため、必然的にドレンパン１０は仕切り板６側端部（側壁部１０ｂ）から先に引き下ろすようになる。
作業者がドレンパン底部１０ｅに手を伸ばして把手部２６を摘み引き下ろすと、ドレンパン１０は吹出し口１２側端部が傾斜上側で、仕切り板６側端部が傾斜下側の斜め姿勢となる。一旦、ドレンパン１０を上記姿勢にしてから、この状態を保持したままドレンパン１０を引き下ろす。ドレンパン１０の吹出し口１２側端部が傾斜上側になっているので、側壁部１０ａが上記フレーム１ａに衝突するのを避けてドレンパン１０を引き下ろすことが可能である。 That is, the drain pan support structure K engages the end portion (side wall portion 10a) of the drain pan 10 between the frame 1a at the lower corner of the main body 1 and the lower end surface of the heat insulating material D, while the other side wall portion 10b. 10d is closely fitted between the side surface of the main body 1 constituting the heat exchange chamber 7B and the partition plate 6, and the drain pan 10 is supported by the main body 1. Therefore, the drain pan 10 is necessarily pulled down first from the partition plate 6 side end portion (side wall portion 10b).
When the operator reaches to the drain pan bottom portion 10e and picks and pulls down the handle portion 26, the drain pan 10 has an oblique posture in which the end portion on the outlet 12 side is inclined upward and the end portion on the partition plate 6 is inclined downward. Once the drain pan 10 is in the above posture, the drain pan 10 is pulled down while maintaining this state. Since the end of the drain pan 10 on the outlet 12 side is inclined upward, the drain pan 10 can be pulled down while avoiding the side wall 10a from colliding with the frame 1a.

また、このとき傾斜下側となる方に１次側ドレン受け部２１が設けられていて、ある程度の量のドレン水が残っている場合がある。しかしながら、１次側ドレン受け部２１は２次側ドレン受け部２２よりも深く形成され、しかもドレンパン１０は１次側ドレン受け部２１を傾斜下側とする斜め姿勢であるので、１次側ドレン受け部２１からドレン水が溢出する虞れがない。
ドレンパン１０の吹出し口１２側端部（側壁部１０ａ）が本体１のドレンパン支持構造体Ｋから抜け出たら、ドレンパン１０を傾斜姿勢から平衡姿勢に変えて下ろし、床面上に置けばよい。ドレンパン１０を平衡姿勢にすれば、さらに１次側ドレン受け部２１からのドレン水の溢出がない。 Further, at this time, the primary drain receiving portion 21 is provided on the lower side of the slope, and a certain amount of drain water may remain. However, since the primary side drain receiving portion 21 is formed deeper than the secondary side drain receiving portion 22 and the drain pan 10 is in an inclined posture with the primary side drain receiving portion 21 being inclined downward, the primary side drain. There is no possibility of drain water overflowing from the receiving part 21.
When the end of the drain pan 10 on the side of the outlet 12 (side wall 10a) comes out of the drain pan support structure K of the main body 1, the drain pan 10 may be lowered from the inclined posture to the equilibrium posture and placed on the floor surface. If the drain pan 10 is in an equilibrium posture, there is no further overflow of drain water from the primary side drain receiving portion 21.

ドレンパン１０を床面上に置いて、必要なメンテナンス作業を終えたら、再びドレンパン１０を本体１に組み込む。このときは当然、ドレンパン１０内にドレン水が無いのであるから、本体１の近傍部位に至るまではドレンパン１０をどのような姿勢で持ち上げても何ら支障がない。
ドレンパン１０が本体１に接触する直前の部位に至ったら、ドレンパン１０の取外し時と同様、吹出し口１２側端部を傾斜上側とし、仕切り板６側端部を傾斜下側とする斜め姿勢となす。そして、ドレンパン１０の吹出し口１２側端部を本体１の熱交換室７Ｂ下面に差し込み、断熱材Ｄとフレーム１ａとの間に挿入し掛合する。 After the drain pan 10 is placed on the floor and necessary maintenance work is completed, the drain pan 10 is assembled into the main body 1 again. At this time, naturally, there is no drain water in the drain pan 10, so there is no problem even if the drain pan 10 is lifted in any posture until reaching the vicinity of the main body 1.
When the drain pan 10 reaches the position immediately before contacting the main body 1, as in the case of removing the drain pan 10, an inclined posture is adopted in which the end on the outlet 12 side is inclined upward and the end on the partition plate 6 is inclined downward. . And the blower outlet 12 side edge part of the drain pan 10 is inserted in the heat exchange chamber 7B lower surface of the main body 1, and it inserts between the heat insulating material D and the flame | frame 1a, and is engaged.

ドレンパン１０の吹出し口１２側端部を本体１に取付けたら、今度は仕切り板６側端部を押上げて、載置部２０を熱交換器９に当接させる。すなわち、熱交換器９がストッパとなって、ドレンパン１０のそれ以上の押上げを規制する。必然的に、ドレンパン１０の各側壁部１０ｂ〜１０ｄはドレンパン支持構造体Ｋに取付け支持される。ドレンパン１０の本体１への取付け時においても、上記把手部２６をもてば極めて作業し易い。
このように、ドレンパン１０の底部１０ｅ下面に把手部２６を設けたから、本体１が天井裏Ｔのごとき室内高所に取付けられるものでありながら、ドレンパン１０のメンテナンス作業にあたって、ドレンパン１０の取外しと取付けが容易となり作業性の向上化を図れる。 When the end of the drain pan 10 on the outlet 12 side is attached to the main body 1, the end of the partition plate 6 is pushed up to bring the mounting portion 20 into contact with the heat exchanger 9. That is, the heat exchanger 9 serves as a stopper and restricts further pushing up of the drain pan 10. Naturally, the side wall portions 10b to 10d of the drain pan 10 are attached to and supported by the drain pan support structure K. Even when the drain pan 10 is attached to the main body 1, it is extremely easy to work with the handle portion 26.
As described above, since the handle portion 26 is provided on the bottom surface of the bottom portion 10e of the drain pan 10, the main body 1 can be mounted at an indoor high place such as the ceiling T. This makes it easier to improve workability.

そして、ドレンパン１０の熱交換器載置部２０を挟んで熱交換空気導通路Ｒの風上側に１次側ドレン受け部２１、風下側に２次側ドレン受け部２２を設け、１次側ドレン受け部２１の深さ寸法を２次側ドレン受け部２２の深さ寸法よりも大に設定し、本体１にドレンパン１０の仕切り板６側端部を傾斜下側とする斜め姿勢にした状態で取外し可能としたドレンパン支持構造体Ｋを備えたので、ドレンパン１０の取外しの途中で、ドレンパン１０に残っているドレン水の溢出を防止できる。
また、本発明は上述した実施の形態そのままに限定されるものではなく、実施段階ではその要旨を逸脱しない範囲で構成要素を変形して具体化できるとともに、上述した実施の形態に開示されている複数の構成要素の適宜な組み合わせにより種々の発明を形成できる。 And the primary side drain receiving part 22 is provided in the windward side of the heat exchange air conduction path R across the heat exchanger mounting part 20 of the drain pan 10, and the secondary side drain receiving part 22 is provided in the leeward side. In a state where the depth dimension of the receiving portion 21 is set to be larger than the depth dimension of the secondary drain receiving portion 22 and the main body 1 is in an inclined posture with the end portion on the partition plate 6 side of the drain pan 10 being inclined downward. Since the drain pan supporting structure K that can be removed is provided, the drain water remaining in the drain pan 10 can be prevented from overflowing during the removal of the drain pan 10.
