　空気調和機６０は、室内熱交換器の表面で凝縮したドレン水を受け入れる図示しないドレンパンを有しており、ドレンパンの上方に間隔を空けて設けられた天井板６１に排水ポンプ１が取付けられる。図３（ａ）に示すように、天井板６１には、複数の貫通孔６２が設けられている。本実施例では、貫通孔６２は３つ設けられている。 The air conditioner 60 has a drain pan (not shown) that receives drain water condensed on the surface of the indoor heat exchanger, and the drainage pump 1 is attached to a ceiling plate 61 that is provided above the drain pan with a space therebetween. As shown in FIG. 3A, the ceiling plate 61 is provided with a plurality of through holes 62. In the present embodiment, three through holes 62 are provided.
　貫通孔６２は、円形の挿通部６３と、挿通部６３に連なるスリット部６４と、を有している。挿通部６３は、取付部材７０の先端部７２の径より大きい径を有している。挿通部６３は、取付部材７０の先端部７２が挿通可能な形状であればよい。スリット部６４は、先端部７２の径（すなわち先端部７２の幅）より小さくかつ柱部７１の径より大きい幅を有している。本実施例において、各貫通孔６２の挿通部６３の中心は仮想円Ｑ１上に配置されている。また、各貫通孔６２のスリット部６４の中心線も仮想円Ｑ１上に配置されている。 The through-hole 62 has a circular insertion part 63 and a slit part 64 connected to the insertion part 63. The insertion part 63 has a diameter larger than the diameter of the tip part 72 of the mounting member 70. The insertion part 63 should just be a shape which the front-end | tip part 72 of the attachment member 70 can penetrate. The slit portion 64 has a width that is smaller than the diameter of the distal end portion 72 (that is, the width of the distal end portion 72) and larger than the diameter of the column portion 71. In the present embodiment, the center of the insertion portion 63 of each through hole 62 is arranged on the virtual circle Q1. Moreover, the center line of the slit part 64 of each through-hole 62 is also arrange | positioned on the virtual circle Q1.
　取付部材７０は、柱状に形成されており、円柱状の柱部７１と、柱部７１の上端（一方の端部）に設けられた円形のフランジ形状の先端部７２と、柱部７１の下端（他方の端部）に設けられた円形のフランジ形状の基端部７３と、を有している。先端部７２は取付部材７０の上側の端部である。基端部７３は取付部材７０の下側の端部である。柱部７１の径は、切り欠き２８の入口から奥に入った部分の幅および天井板６１の貫通孔６２のスリット部６４の幅より小さい。先端部７２の径は、スリット部６４の幅より大きい。基端部７３の径は、切り欠き２８の入口から奥に入った部分の幅より大きい。先端部７２および基端部７３は、柱部７１から径方向外側に膨らんだ幅広部であればよい。本実施例では、取付部材７０を３つ有している。 The attachment member 70 is formed in a columnar shape, and includes a columnar column portion 71, a circular flange-shaped tip portion 72 provided at the upper end (one end portion) of the column portion 71, and the lower end of the column portion 71. And a circular flange-shaped base end portion 73 provided at (the other end portion). The distal end portion 72 is an upper end portion of the attachment member 70. The base end portion 73 is the lower end portion of the attachment member 70. The diameter of the column portion 71 is smaller than the width of the portion entering from the entrance of the notch 28 and the width of the slit portion 64 of the through hole 62 of the ceiling plate 61. The diameter of the distal end portion 72 is larger than the width of the slit portion 64. The diameter of the base end portion 73 is larger than the width of the portion entering from the entrance to the notch 28. The distal end portion 72 and the base end portion 73 may be wide portions that swell radially outward from the column portion 71. In this embodiment, there are three attachment members 70.
　本実施例において、排水ポンプ１は、取付部材７０によって天井板６１に自重により垂下される（ぶら下がる）ように取付けられている。ここで、「自重により垂下される」とは、他の力を受けることなく自らの重さのみで垂れ下がることを言う。そのため、例えば、過剰な振れを規制するように、排水ポンプ１がワイヤーでドレンパンなどと接続された状態で垂下されている構成などは、ワイヤーにより排水ポンプ１が引っ張る力を受けているため「自重により垂下される」に含まれない。もちろん、このような、ワイヤーなどによって排水ポンプ1の振れなどを規制する構成を採用してもよい。 In the present embodiment, the drainage pump 1 is attached to the ceiling plate 61 by the attachment member 70 so as to be suspended (hangs down) by its own weight. Here, “hangs down by its own weight” means that it hangs down only by its own weight without receiving any other force. Therefore, for example, a configuration in which the drainage pump 1 is suspended in a state where it is connected to a drain pan or the like with a wire so as to restrict excessive vibrations is received by the force of the drainage pump 1 being pulled by the wire. Is not included. Of course, such a configuration that regulates the swing of the drainage pump 1 by a wire or the like may be adopted.
　取付部材７０は、天井板６１およびカバー２０と別体である。排水ポンプ１は、取付部材７０の上端が天井板６１に係止されかつ下端がカバー２０に係止されることにより、天井板６１に垂下されるように取付けられる。 The mounting member 70 is separate from the ceiling board 61 and the cover 20. The drainage pump 1 is mounted so as to be suspended from the ceiling plate 61 by the upper end of the mounting member 70 being locked to the ceiling plate 61 and the lower end being locked to the cover 20.
　具体的には、取付部材７０の先端部７２は、天井板６１に設けられた貫通孔６２に挿通されるとともに、垂下状態となるよう貫通孔６２の上側の縁部６２ａに引っ掛かる円環状の下向き面７２ａを有している。取付部材７０の基端部７３は、カバー２０の取付部２５の平板部２７に設けられた切り欠き２８に挿通されるとともに、平板部２７が垂下状態となるよう切り欠き２８の下側の縁部２８ａに引っ掛かる円環状の上向き面７３ａを有している。なお、先端部７２は円形以外のフランジ形状であってもよく、下向き面７２ａは円環状以外の環状であってもよい。基端部７３も同様である。 Specifically, the distal end portion 72 of the mounting member 70 is inserted into a through hole 62 provided in the ceiling plate 61 and is downwardly annularly hooked on the upper edge portion 62a of the through hole 62 so as to be suspended. It has a surface 72a. The base end portion 73 of the attachment member 70 is inserted into a notch 28 provided in the flat plate portion 27 of the attachment portion 25 of the cover 20 and the lower edge of the notch 28 so that the flat plate portion 27 is in a suspended state. It has an annular upward surface 73a that is hooked on the portion 28a. The distal end portion 72 may have a flange shape other than a circular shape, and the downward surface 72a may have an annular shape other than an annular shape. The same applies to the base end portion 73.
　取付部材７０は、天井板６１およびカバー２０より曲げ弾性率が小さい。取付部材７０は、天井板６１およびカバー２０の少なくとも一方より曲げ弾性率が小さいことが好ましい。このようにすることで、カバー２０から天井板６１に伝搬する振動が、取付部材７０において効果的に減衰される。 The mounting member 70 has a lower bending elastic modulus than the ceiling board 61 and the cover 20. The attachment member 70 preferably has a lower bending elastic modulus than at least one of the ceiling plate 61 and the cover 20. By doing so, vibration propagating from the cover 20 to the ceiling board 61 is effectively attenuated in the mounting member 70.
　次に、排水ポンプ１を、取付部材７０を用いて空気調和機６０の天井板６１に取付ける方法について説明する。 Next, a method for attaching the drainage pump 1 to the ceiling plate 61 of the air conditioner 60 using the attachment member 70 will be described.
　まず、排水ポンプ１が有する複数の取付部２５の平板部２７に取付部材７０を取付ける。具体的には、各平板部２７に設けられた切り欠き２８に、入口から取付部材７０の柱部７１を押し込む。これにより、取付部材７０の柱部７１が切り欠き２８に挿通された状態で保持される。 First, the attachment member 70 is attached to the flat plate portions 27 of the plurality of attachment portions 25 of the drainage pump 1. Specifically, the column portion 71 of the mounting member 70 is pushed into the notch 28 provided in each flat plate portion 27 from the entrance. Thereby, the column part 71 of the attachment member 70 is hold | maintained in the state penetrated by the notch 28. FIG.
　次に、各平板部２７に取付けられた取付部材７０の先端部７２を、空気調和機６０の天井板６１に設けられた貫通孔６２の挿通部６３に挿通する。そして、上方から見たときに反時計回りとなる方向に排水ポンプ１を回転させて、取付部材７０の柱部７１を貫通孔６２のスリット部６４に進入するようにスライド移動させる。 Next, the distal end portion 72 of the attachment member 70 attached to each flat plate portion 27 is inserted into the insertion portion 63 of the through hole 62 provided in the ceiling plate 61 of the air conditioner 60. Then, the drainage pump 1 is rotated in a counterclockwise direction when viewed from above, and the column portion 71 of the attachment member 70 is slid so as to enter the slit portion 64 of the through hole 62.
　これにより、取付部材７０の先端部７２の下向き面７２ａが貫通孔６２の上側の縁部６２ａに引っ掛かって垂下状態（ぶら下がり状態）となる。また、取付部材７０の基端部７３の上向き面７３ａが切り欠き２８の下側の縁部２８ａに引っ掛かって平板部２７が垂下状態となる。このようにして、排水ポンプ１が取付部材７０によって空気調和機６０の天井板６１に垂下状態で取付けられる。このとき、排水ポンプ１のカバー２０（平板部２７）と天井板６１とが間隔Ｄを空けて対向して配置される。間隔Ｄは、０．５ｍｍ～１００ｍｍが好ましく、１ｍｍ～５０ｍｍがさらに好ましい。 Thereby, the downward surface 72a of the distal end portion 72 of the mounting member 70 is hooked on the upper edge portion 62a of the through hole 62 to be in a suspended state (hanging state). Further, the upward surface 73a of the base end portion 73 of the mounting member 70 is hooked on the lower edge portion 28a of the notch 28, so that the flat plate portion 27 is suspended. In this manner, the drainage pump 1 is attached to the ceiling plate 61 of the air conditioner 60 in a suspended state by the attachment member 70. At this time, the cover 20 (flat plate portion 27) of the drainage pump 1 and the ceiling plate 61 are arranged to face each other with a gap D therebetween. The interval D is preferably 0.5 mm to 100 mm, and more preferably 1 mm to 50 mm.
　以上説明したように、本実施例によれば、排水ポンプ１は、取付部材７０によって、カバー２０が空気調和機６０の天井板６１と間隔を空けて天井板６１に取付けられる。このようにしたことから、排水ポンプ１のカバー２０が天井板６１に接触しないので、カバー２０から天井板６１に直接的に振動が伝搬することを回避できる。そのため、排水ポンプ１が取付けられる天井板６１へのモータ４０の振動の伝搬を抑制することができ、動作時の静粛性を図ることができる。 As described above, according to the present embodiment, in the drainage pump 1, the cover 20 is attached to the ceiling plate 61 with the attachment member 70 spaced from the ceiling plate 61 of the air conditioner 60. Since it did in this way, since the cover 20 of the drainage pump 1 does not contact the ceiling board 61, it can avoid that a vibration propagates directly from the cover 20 to the ceiling board 61. Therefore, propagation of vibration of the motor 40 to the ceiling plate 61 to which the drainage pump 1 is attached can be suppressed, and silence during operation can be achieved.
　また、排水ポンプ１は、取付部材７０によって、天井板６１に自重により垂下されるように取付けられる。このようにすることで、排水ポンプ１が、固定されることなく移動の自由度をもって自重により排水ポンプ１が天井板６１にぶら下がる。そのため、排水ポンプ１と天井板６１とが緩く接続されているので、排水ポンプ１が取付けられる天井板６１へのモータ４０の振動の伝搬をさらに抑制することができ、動作時の静粛性を図ることができる。また、排水ポンプ１は、移動の自由度をもって天井板６１にぶら下がるため、モータ４０が回転すると自律的にバランスをとって振動の少ない姿勢を保つことができる。 Further, the drainage pump 1 is attached by the attachment member 70 so as to be suspended from the ceiling plate 61 by its own weight. By doing in this way, the drainage pump 1 hangs on the ceiling board 61 by its own weight with freedom of movement without being fixed. Therefore, since the drainage pump 1 and the ceiling plate 61 are loosely connected, it is possible to further suppress the propagation of vibration of the motor 40 to the ceiling plate 61 to which the drainage pump 1 is attached, thereby achieving quietness during operation. be able to. Further, since the drainage pump 1 is suspended from the ceiling plate 61 with a degree of freedom of movement, when the motor 40 rotates, it can be balanced autonomously and maintain a posture with little vibration.
　また、取付部材７０は、カバー２０と別体である。排水ポンプ１は、取付部材７０の上端の先端部７２が天井板６１に係止されかつ下端の基端部７３がカバー２０に係止されることにより、天井板６１に取付けられる。取付部材７０の先端部７２は、天井板６１に設けられた貫通孔６２に挿通されるとともに、貫通孔６２の上側の縁部６２ａに引っ掛かる。取付部材７０の基端部７３は、カバー２０に設けられた切り欠き２８に挿通されるとともに、切り欠き２８の下側の縁部２８ａに引っ掛かる。このようにすることで、比較的簡易な構成で排水ポンプ１を天井板６１に取付けることができる。 The mounting member 70 is separate from the cover 20. The drainage pump 1 is attached to the ceiling plate 61 by engaging the top end 72 of the attachment member 70 with the ceiling plate 61 and the base end 73 of the bottom end with the cover 20. The distal end portion 72 of the attachment member 70 is inserted into the through hole 62 provided in the ceiling plate 61 and is caught by the upper edge portion 62 a of the through hole 62. The base end portion 73 of the attachment member 70 is inserted into the notch 28 provided in the cover 20 and is caught by the lower edge portion 28 a of the notch 28. By doing in this way, the drainage pump 1 can be attached to the ceiling board 61 with a comparatively simple structure.
　また、取付部材７０の先端部７２は、外側に膨らむ幅広部である。天井板６１の貫通孔６２は、取付部材７０の先端部７２が挿通可能な形状を有する挿通部６３と、挿通部６３に連なり先端部７２の幅より小さい幅を有するスリット部６４と、を有している。このようにすることで、取付部材７０の先端部７２を貫通孔６２の挿通部６３に挿通したのちスリット部６４に進入するようにスライド移動させることで、排水ポンプ１を天井板６１に容易に取付けることができる。 Also, the tip 72 of the mounting member 70 is a wide part that bulges outward. The through hole 62 of the ceiling plate 61 includes an insertion portion 63 having a shape into which the distal end portion 72 of the mounting member 70 can be inserted, and a slit portion 64 that is continuous with the insertion portion 63 and has a width smaller than the width of the distal end portion 72. doing. By doing so, the drainage pump 1 can be easily moved to the ceiling plate 61 by sliding the tip 72 of the mounting member 70 so as to enter the slit 64 after passing through the insertion 63 of the through hole 62. Can be installed.

　取付部材８０は、柱状に形成されており、円柱状の柱部８１と、柱部８１の上端に設けられた円形のフランジ形状の先端部８２と、を有している。また、取付部材８０の基端部８３は、排水ポンプ１Ａの上カバー２２と一体に設けられている。先端部８２は取付部材８０の上側の端部である。基端部８３は取付部材８０の下側の端部である。柱部８１の径は、天井板６１の貫通孔６２のスリット部６４の幅より小さい。先端部８２の径は、スリット部６４の幅より大きい。先端部８２は、柱部８１から径方向外側に膨らんだ幅広部であればよい。本実施例では、取付部材８０を３つ有している。 The mounting member 80 is formed in a columnar shape, and includes a columnar column portion 81 and a circular flange-shaped tip portion 82 provided at the upper end of the column portion 81. Further, the base end portion 83 of the mounting member 80 is provided integrally with the upper cover 22 of the drainage pump 1A. The distal end portion 82 is an upper end portion of the attachment member 80. The base end portion 83 is a lower end portion of the attachment member 80. The diameter of the column part 81 is smaller than the width of the slit part 64 of the through hole 62 of the ceiling plate 61. The diameter of the tip portion 82 is larger than the width of the slit portion 64. The distal end portion 82 may be a wide portion that swells radially outward from the column portion 81. In this embodiment, there are three attachment members 80.
　取付部材８０の先端部８２は、天井板６１に設けられた貫通孔６２に挿通されるとともに、垂下状態となるよう貫通孔６２の上側の縁部６２ａに引っ掛かる円環状の下向き面８２ａを有している。なお、先端部８２は円形以外のフランジ形状であってもよく、下向き面８２ａは円環状以外の環状であってもよい。 The front end portion 82 of the attachment member 80 is inserted into a through hole 62 provided in the ceiling plate 61, and has an annular downward surface 82a that is hooked on an upper edge portion 62a of the through hole 62 so as to be in a suspended state. ing. The distal end portion 82 may have a flange shape other than a circular shape, and the downward surface 82a may have an annular shape other than an annular shape.
　取付部材８０は、天井板６１およびカバー２０より曲げ弾性率が小さい。取付部材８０は、天井板６１およびカバー２０の少なくとも一方より曲げ弾性率が小さいことが好ましい。このようにすることで、カバー２０から天井板６１に伝搬する振動が、取付部材８０において効果的に減衰される。 The mounting member 80 has a lower bending elastic modulus than the ceiling board 61 and the cover 20. The attachment member 80 preferably has a lower bending elastic modulus than at least one of the ceiling plate 61 and the cover 20.

Moreover, when the drainage pump 1A is viewed from the vertical direction, the outermost end of the cover 20 is inscribed in a virtual circle P2 having a diameter L2 smaller than the diameter L1 of the virtual circle P1 of the first embodiment.
　取付部材８０の先端部８２は、第１実施例の取付部材７０の先端部７２と同様の取付方法で空気調和機６０の天井板６１に取付けられる。このとき、排水ポンプ１Ａのカバー２０（上カバー２２の上面２２ａ）と天井板６１とが間隔Ｄを空けて対向して配置される。間隔Ｄは、０．５ｍｍ～１００ｍｍが好ましく、１ｍｍ～５０ｍｍがさらに好ましい。 The front end portion 82 of the mounting member 80 is attached to the ceiling plate 61 of the air conditioner 60 by the same mounting method as the front end portion 72 of the mounting member 70 of the first embodiment.

The distal end portion 92 is inserted into the through hole 65 of the ceiling plate 61 in a state where the plurality of elastic pieces are elastically deformed toward the center side. The base end portion 93 of the attachment member 90 is a wide portion that swells outward, and slits are formed so as to form a plurality of elastic pieces. The base end portion 93 may be inserted into the notch 28 of the cover 20 with a plurality of elastic pieces elastically deformed toward the center. Since it did in this way, the drainage pump 1 can be easily attached to the ceiling board 61. FIG.
