In addition, the interior of the rotor bucket is partitioned into multiple storage chambers (17A, 17B, 17C) by partition plates (15) in the axial direction of the rotational axis, and when the rotor bucket inclines due to the weight of drain water, the drain water from the multiple storage chambers is dispersed and discharged in the axial direction of the rotational axis.
Description
本発明は冷房ドレイン水を用いた室外機の冷却装置に関し、特にローターバケットの回転軸の傾きによる影響を少なくし、又ローターバケットの回転軸回りのバランスの崩れを修正して熱交換器の冷却効率を保証できるようにした装置に関する。
The present invention relates to a cooling device for an outdoor unit that uses cooling drain water, and in particular, reduces the influence of the inclination of the rotation axis of the rotor bucket, and corrects the collapse of the balance around the rotation axis of the rotor bucket to cool the heat exchanger. The present invention relates to a device that can guarantee efficiency.
冷房装置では、圧縮機で圧縮した冷媒と、室外機に取り入れた大気とを室外機の熱交換器で熱交換させることによって冷媒を凝縮し、この凝縮した冷媒を室内機に循環させて気化させることによって、室内から取り入れた空気の熱を奪い、室内機から冷気を室内に放出させ、室内を快適な温度に保持するという方式が採用されている。
In the cooling device, the refrigerant is condensed by exchanging heat between the refrigerant compressed by the compressor and the air taken into the outdoor unit by the heat exchanger of the outdoor unit, and the condensed refrigerant is circulated to the indoor unit to be vaporized. Thus, a system is adopted in which the heat of the air taken in from the room is taken, cold air is discharged from the indoor unit into the room, and the room is kept at a comfortable temperature.
しかし、夏期の猛暑下においては、室外機を最大限稼働させているにもかかわらず、十分な冷房能力が得られず、電力が無駄に消費されるばかりでなく、冷房装置をフル稼働させているので、装置の耐久性が低下する。これは夏期の昼間においては外気温が３０°Ｃを越え、特にオフィスビルの屋上等では輻射熱等によって室外機周囲の外気温が４０°Ｃを越えることによって室外機の熱交換器における熱交換効率が低下し、しかも熱交換器の汚れ等が熱交換器の効率の低下を助長していることが原因である。
However, under extreme summer heat, despite the maximum outdoor unit operation, sufficient cooling capacity is not obtained, and not only power is wasted, but the cooling system is fully operated. As a result, the durability of the device decreases. This is because the outdoor temperature exceeds 30 ° C during the daytime in the summer, and the heat exchange efficiency in the heat exchanger of the outdoor unit is increased especially when the outdoor temperature around the outdoor unit exceeds 40 ° C due to radiant heat etc. This is because the contamination of the heat exchanger reduces the efficiency of the heat exchanger.
これに対し、噴霧ノズルによって熱交換器のフィンに向けて冷却水を噴霧し、冷却水の蒸発熱を利用して熱交換効率を向上させ、もって所望の冷却能力を確保しつつ電力消費量を低減させるようにした室外機の冷却装置が提案されている（特許文献１、特許文献２、参照）。
On the other hand, the cooling water is sprayed toward the fins of the heat exchanger by the spray nozzle, the heat exchange efficiency is improved by utilizing the heat of evaporation of the cooling water, and the power consumption can be reduced while ensuring the desired cooling capacity. A cooling device for an outdoor unit that has been reduced has been proposed (see Patent Document 1 and Patent Document 2).
しかし、従来の室外機の冷却装置では冷却水に水道水や工業用水を利用しているので、大量の冷却水を必要とし、水道料金等が高くなるなど、設備コスト・稼働コスト共に高い。しかも、熱交換器のフィンが直接噴霧した水道水等で常に濡れた状態となるので、水道水等に含まれる塩素、鉄分、カルシウム成分、二酸化シリカ等が凝縮器のフィンに付着し、熱交換器のフィンや導管を短期間のうちに腐食させていた。
However, since the conventional outdoor unit cooling system uses tap water or industrial water as the cooling water, a large amount of cooling water is required, and the cost of water is high. Moreover, since the heat exchanger fins are always wet with directly sprayed tap water, etc., chlorine, iron, calcium components, silica dioxide, etc. contained in the tap water adhere to the fins of the condenser and heat exchange The vessel fins and conduits were corroded in a short period of time.
他方、本件発明者らは、冷房運転で発生してアルミニウムや鋼パイプなどで構成される熱交換器の金属を侵す滅菌塩素やシリカ、カルシウムなどの成分を含まず、かつ水道水や工業用水、地下水よりも遥かに低温のドレイン水（結露水）をローターバケットに貯留し、一定量貯まったときにローターバケットのバランスが崩れて傾動し、ドレイン水が室外機の熱交換器の空気取入れ面に向けて均等に放流されることによって熱交換器を冷却し、設備コスト高及び稼働コスト高を招来することなく、冷房能力を確保しつつ電力消費量を低減できるとともに、所期の耐久性を保証できるようにした室外機の冷却装置を提案するに至った（特許文献３、特許文献４）。
On the other hand, the inventors of the present invention do not contain components such as sterilized chlorine, silica, calcium, and the like, which are generated by cooling operation and attack the metal of the heat exchanger composed of aluminum and steel pipes, and tap water, industrial water, Drain water (condensation water) that is much colder than groundwater is stored in the rotor bucket, and when a certain amount of water is stored, the rotor bucket is unbalanced and tilts, and the drain water is collected on the air intake surface of the heat exchanger of the outdoor unit. The heat exchanger is cooled evenly to cool the heat exchanger, reducing the power consumption while ensuring the cooling capacity without incurring high equipment costs and high operating costs, and guaranteeing the expected durability It came to propose the cooling device of the outdoor unit which enabled it (patent document 3, patent document 4).
ところで、冷却装置を室外機に設置する場合、室外機のハウジング頂面に支持ステーや取付けブラケットを前方に延びて取付け、この支持ステーに冷却装置に搭載し取付けブラケットに冷却装置を固定することによって冷却装置を室外機に設置することが行われている。
By the way, when installing a cooling device in an outdoor unit, a support stay and a mounting bracket are attached to the top surface of the housing of the outdoor unit so as to extend forward, and are mounted on the cooling device and fixed to the mounting bracket. A cooling device is installed in an outdoor unit.
しかし、上記特許文献３、４記載の室外機の冷却装置では冷却装置を支持ステーに搭載し取付けブラケットに固定している構造上、冷却装置を水平に設置することが難しいことがある。例えば、冷却装置が室外機の横幅方向（ローターバケットの長手方向）に３度程度傾くと、冷却装置内ではローターバケットの長手方向の一方に極端に偏ってドレイン水が貯留され放流される現象が起こり、室外機の熱交換器の一部のみがドレイン水によって冷却される結果、熱交換効率が期待したほどアップできないことがあった。
However, in the outdoor unit cooling apparatus described in Patent Documents 3 and 4, it is sometimes difficult to install the cooling apparatus horizontally because of the structure in which the cooling apparatus is mounted on a support stay and fixed to a mounting bracket. For example, when the cooling device is inclined about 3 degrees in the width direction of the outdoor unit (longitudinal direction of the rotor bucket), there is a phenomenon in which drain water is stored and discharged extremely biased to one side in the longitudinal direction of the rotor bucket in the cooling device. As a result, only a part of the heat exchanger of the outdoor unit is cooled by the drain water, so that the heat exchange efficiency may not be improved as expected.
また、上記特許文献３、４の室外機の冷却装置では矩形状の基部に直角三角形状の突片を一体に形成したＬ字状金具を製作し、その基部をローターバケットの両側面に点溶接などで固定し、Ｌ字状金具の突片をケーシング側のＶ字状の受具に搭載し、Ｌ字状金具の突片下端辺によってローターバケットの回転軸を構成しているが、Ｌ字状金具の突片下端辺がバケットの重心を通る線上に位置するとは限らず、バケットが正しい姿勢になっておらず、回転軸回りに前方又は後方に傾き、少量のドレイン水の貯留でバランスが崩れて放流動作を開始してしまうことがあった。
Further, in the outdoor unit cooling apparatus of Patent Documents 3 and 4, an L-shaped metal fitting in which right-angled triangular protrusions are integrally formed on a rectangular base is manufactured, and the base is spot welded to both side surfaces of the rotor bucket. The L-shaped bracket protrusion is mounted on a V-shaped receiver on the casing side, and the lower end of the L-shaped bracket protrusion forms the rotating shaft of the rotor bucket. The bottom end of the protruding piece of the metal fitting is not necessarily located on the line passing through the center of gravity of the bucket, the bucket is not in the correct posture, tilts forward or backward around the rotation axis, and balance is obtained by storing a small amount of drain water. It sometimes collapsed and started to discharge.
本発明はかかる問題点に鑑み、冷却装置を室外機に設置したときにローターバケットの回転軸の軸線方向に対する傾きがあってもドレイン水を極端に偏って放流されることがなく、又ローターバケットの回転軸回りの傾きがあってもローターバケットを正しい姿勢に調整することもできるようにした冷房ドレイン水を用いた室外機の冷却装置を提供することを課題とする。
In view of such a problem, the present invention does not discharge drain water in an extremely biased manner even when the cooling device is installed in an outdoor unit, even if there is an inclination with respect to the axial direction of the rotation axis of the rotor bucket. It is an object of the present invention to provide a cooling device for an outdoor unit using cooling drain water that can adjust a rotor bucket to a correct posture even when there is an inclination around the rotation axis.

Fixed to both end wall surfaces of the bucket, V-shaped receivers are fixed to both inner end surfaces of the casing, and the protrusions of the L-shaped members are mounted on the receivers, and the lower end sides of the protrusions are The rotary shaft of the rotor bucket is configured, the interior of the rotor bucket is partitioned into a plurality of storage chambers in the axial direction of the rotary shaft by a partition plate, and the rotor bucket is tilted by the weight of drain water. The drain water is dispersed and discharged in the axial direction of the rotating shaft from each storage chamber.
本発明の特徴の１つは仕切り板によってローターバケット内を回転軸の軸線方向に複数の貯留室に仕切るようにした点にある。
One of the features of the present invention is that the inside of the rotor bucket is partitioned into a plurality of storage chambers in the axial direction of the rotating shaft by a partition plate.
これにより、室内機のドレイン水はローターバケット内の複数の各貯留室に分散して貯留されるので、冷却装置がローターバケットの回転軸の軸線方向に対して傾いて設置された場合であっても、複数の各貯留室からドレイン水が放流され、ドレイン水の放流がローターバケットの一方に極端に偏ることはなく、室外機の熱交換効率を保証できる。
Thereby, since the drain water of the indoor unit is distributed and stored in each of the plurality of storage chambers in the rotor bucket, the cooling device is installed inclined with respect to the axial direction of the rotation axis of the rotor bucket. However, the drain water is discharged from each of the plurality of storage chambers, and the discharge of the drain water is not extremely biased to one of the rotor buckets, and the heat exchange efficiency of the outdoor unit can be guaranteed.
ローターバケット内の複数の各貯留室に分散して貯留する上で、仕切り板の高さが大切である。仕切り板が高すぎると、ドレイン水の大部分がケーシングのドレイン水流入口の直下の貯留室に貯留され、ローターバケットが傾動するまでの間に他の貯留室にはドレイン水が分散して貯留され難くなるからである。そこで、仕切り板はローターバケットが傾動を開始するドレイン水の水位よりも低い高さとするのがよい。
The height of the partition plate is important for distributing and storing in a plurality of storage chambers in the rotor bucket. If the partition plate is too high, most of the drain water is stored in the storage chamber directly under the drain water inlet of the casing, and the drain water is distributed and stored in the other storage chambers until the rotor bucket tilts. Because it becomes difficult. Therefore, it is preferable that the partition plate has a height lower than the drain water level at which the rotor bucket starts to tilt.
また、ローターバケットの側壁面の上端縁は真っ直ぐでもよいが、上端縁を、凹凸を繰り返した形状、例えば鋸歯状に形成すると、複数の各貯留室からのドレイン水を側壁面の上端縁の凹凸によって回転軸の軸線方向に分散することができる。
Further, the upper end edge of the side wall surface of the rotor bucket may be straight, but if the upper end edge is formed into a shape with repeated unevenness, for example, a sawtooth shape, the drain water from each of the plurality of storage chambers is uneven at the upper end edge of the side wall surface. Can disperse in the axial direction of the rotating shaft.
上記ではローターバケットの回転軸の軸線方向に対する傾きがある場合の対策であったが、ローターバケットの回転軸回りの傾きがある場合における対策も必要である。
In the above, measures were taken when there was an inclination with respect to the axial direction of the rotation axis of the rotor bucket, but measures are also necessary when there is an inclination around the rotation axis of the rotor bucket.

また、重錘の揺動角度を調整することによってローターバケットの重心位置を変化させることができるので、この重錘をローターバケットの貯水量の増減に利用することもできる。
Also, since the position of the center of gravity of the rotor bucket can be changed by adjusting the swing angle of the weight, this weight can also be used to increase or decrease the amount of water stored in the rotor bucket.

以下、本発明を図面に示す具体例に基づいて詳細に説明する。図１ないし図７は本発明に係る冷房ドレイン水を用いた室外機の冷却装置の好ましい実施形態を示す。図において、室外機２０は屋外に設置され、室内機３０は室内に設置され、室外機２０と室内機３０との間には循環パイプ（図示せず）が設けられて冷媒が循環されるようになっている。
Hereinafter, the present invention will be described in detail based on specific examples shown in the drawings. 1 to 7 show a preferred embodiment of an outdoor unit cooling apparatus using cooling drain water according to the present invention. In the figure, the outdoor unit 20 is installed outdoors, the indoor unit 30 is installed indoors, and a circulation pipe (not shown) is provided between the outdoor unit 20 and the indoor unit 30 so that the refrigerant is circulated. It has become.
室外機２０ではハウジング２２内に熱交換器２１及びファン（図示せず）が設けられ、室外機ハウジング２０内にはファンによって大気が取り込まれ、熱交換器２１のフィン（空気取入れ面）で取り入れた空気と圧縮した冷媒とが熱交換されるようになっている。
In the outdoor unit 20, a heat exchanger 21 and a fan (not shown) are provided in the housing 22, and air is taken into the outdoor unit housing 20 by the fan, and is taken in by fins (air intake surfaces) of the heat exchanger 21. Heat is exchanged between the compressed air and the compressed refrigerant.
また、室外機２０にはハウジング２２の天板に冷却装置１０が左右の支持ステー４０によって冷却装置１０のケーシング１０Ａの放流口１１が室外機２０の熱交換器２１のフィンより前方に位置するように取付けられている。
In the outdoor unit 20, the cooling device 10 is placed on the top plate of the housing 22 so that the outlet 11 of the casing 10 </ b> A of the cooling device 10 is positioned in front of the fins of the heat exchanger 21 of the outdoor unit 20 by the left and right support stays 40. Installed on.
この冷却装置１０のケーシング１０Ａはほぼ密閉された直方体形状をなし、ケーシング１０Ａの底壁面には長溝状の放流口１１が長手方向のほぼ全長にわたって形成され、放流口１１の一側縁には金属薄板製（又はポリカーボネイト薄板製）のガイド板１２が斜下方に延びるように取付けられ、放流口１１から放流されるドレイン水が室外機２０の熱交換器２１のフィンに向けて案内されるようになっている。
A casing 10A of the cooling device 10 has a substantially sealed rectangular parallelepiped shape. A long groove-like outlet 11 is formed on the bottom wall surface of the casing 10A over almost the entire length in the longitudinal direction, and a metal is formed on one side edge of the outlet 11. A thin plate (or polycarbonate thin plate) guide plate 12 is attached so as to extend obliquely downward, so that drain water discharged from the discharge port 11 is guided toward the fins of the heat exchanger 21 of the outdoor unit 20. It has become.
また、冷却装置１０のケーシング１０Ａ内にはローターバケット１３が回転軸回りに傾動自在に内装されている。ローターバケット１３は９０°前後の角度をなす断面Ｖ字状をなす前後一対の側壁板１３Ａを長手方向に連続させその両端に左右一対のロータ１３Ｂを固定して構成され、ロータ１３Ｂの外面にはＬ字状金具１４が固定され、Ｌ字状金具１４は矩形状の基部１４Ａに直角三角形状の突片１４Ｂを直角に折り曲げた形状に形成されている。
Further, a rotor bucket 13 is mounted in the casing 10A of the cooling device 10 so as to be tiltable about the rotation axis. The rotor bucket 13 is constituted by a pair of front and rear side wall plates 13A having a V-shaped cross section having an angle of about 90 ° in the longitudinal direction and a pair of left and right rotors 13B fixed to both ends thereof. An L-shaped metal fitting 14 is fixed, and the L-shaped metal fitting 14 is formed in a shape in which a right-angled triangular protrusion 14B is bent at a right angle on a rectangular base portion 14A.
他方、冷却装置１０のケーシング１０Ａは矩形函体１０Ａ－１と蓋１０Ａ－２とから構成され、蓋１０Ａ－２の長手方向の一側部にはドレイン水の流入パイプ１０Ａ－３が取付けられ、室内機３０からのドレイン水を送給するホース３１が接続されるようになっている。
On the other hand, the casing 10A of the cooling device 10 is composed of a rectangular box 10A-1 and a lid 10A-2, and a drain water inflow pipe 10A-3 is attached to one side of the lid 10A-2 in the longitudinal direction. A hose 31 for supplying drain water from the indoor unit 30 is connected.
また、矩形函体１０Ａ－１の両端壁内面には１２０°前後の角度をなすＶ字状の受け具１０Ａ－３が固定され、受け具１０Ａ－３にはローターバケット１３のＬ字状金具１４の突片１４Ｂが搭載され、ローターバケット１３は所定量のドレイン水を貯留したときにＬ字状金具１４の突片１４Ｂの下端辺を回転軸として傾動されるようになっている。
Further, a V-shaped receiver 10A-3 having an angle of about 120 ° is fixed to the inner surfaces of both end walls of the rectangular box 10A-1, and the L-shaped bracket 14 of the rotor bucket 13 is fixed to the receiver 10A-3. The projecting piece 14B is mounted, and the rotor bucket 13 is tilted about the lower end side of the projecting piece 14B of the L-shaped metal fitting 14 when a predetermined amount of drain water is stored.
また、ローターバケット１３内は仕切り板１５によって長手方向に３つの貯留室１７Ａ、１７Ｂ、１７Ｃに仕切られ、仕切り板１５はローターバケット１３が傾動を開始するドレイン水の水位よりも低い高さに設定され、又ローターバケット１３の側壁板１３Ａには板状の重錘１６がその一端部を中心に揺動可能に取付けられ、さらにローターバケット１３の側壁板１３Ａの上端縁は高さ３ｍｍ、角度９０°をなす鋸歯状に形成されている。
The rotor bucket 13 is partitioned into three storage chambers 17A, 17B, and 17C in the longitudinal direction by a partition plate 15, and the partition plate 15 is set to a height lower than the water level of the drain water at which the rotor bucket 13 starts to tilt. Further, a plate-like weight 16 is attached to the side wall plate 13A of the rotor bucket 13 so as to be able to swing around one end thereof, and the upper end edge of the side wall plate 13A of the rotor bucket 13 has a height of 3 mm and an angle of 90 mm. It is formed in a sawtooth shape that forms an angle.
冷房装置を作動させると、室外機２０のフィンにはブロアのファンによって大気が取り入れられる一方、圧縮機（図示せず）では冷媒が圧縮され、この圧縮した冷媒と、室外機２０に取り入れた大気とが室外機２０の熱交換器２１フィンで熱交換され、これによって冷媒が凝縮される。この凝縮された冷媒は室内機３０に循環され、気化することによって、室内から取り入れた空気の熱が奪われ、室内機３０からは冷気が室内に放出され、室内が快適な温度に保持される。
When the air conditioner is operated, the air is taken into the fins of the outdoor unit 20 by the blower fan, while the compressor (not shown) compresses the refrigerant, and the compressed refrigerant and the air taken into the outdoor unit 20 are compressed. Are heat-exchanged by the heat exchanger 21 fins of the outdoor unit 20, thereby condensing the refrigerant. The condensed refrigerant is circulated and vaporized in the indoor unit 30, whereby the heat of the air taken in from the room is taken away, and cool air is released from the indoor unit 30 into the room, and the room is kept at a comfortable temperature. .
その際、室内機３０で冷媒と室内の空気が熱交換されると、ドレイン水（凝結水）が発生し、ドレイン水は室内機３０からホース３１によって冷却装置１０に案内されてケーシング１０Ａ内に流入し、ローターバケット１３に貯留される。ローターバケット１３内に所定量のドレイン水が貯留され、ドレイン水の水位が回転軸のレベルを越えるようになると重量バランスが崩れ、ローターバケット１３はＬ字状金具１４の突辺１３Ｂの下端辺を中心に傾動し、ローターバケット１３内のドレイン水は流出し、ケーシング１０Ａの放流口１１及びガイド板１２によって室外機２０の熱交換器２１フィンに向けて放流され、フィンがドレイン水で濡れ、フィンの熱によって蒸発され、冷媒の凝縮能力を補助して冷房能力の低下を防ぎ、運転エネルギーの省力化が実現される。
At that time, when the indoor unit 30 exchanges heat between the refrigerant and the indoor air, drain water (condensed water) is generated, and the drain water is guided from the indoor unit 30 to the cooling device 10 by the hose 31 and into the casing 10A. It flows in and is stored in the rotor bucket 13. When a predetermined amount of drain water is stored in the rotor bucket 13 and the water level of the drain water exceeds the level of the rotating shaft, the weight balance is lost, and the rotor bucket 13 moves the lower end side of the projecting side 13B of the L-shaped bracket 14. Tilt to the center, drain water in the rotor bucket 13 flows out and is discharged toward the heat exchanger 21 fin of the outdoor unit 20 by the discharge port 11 and the guide plate 12 of the casing 10A. It is evaporated by the heat of the heat and assists the refrigerant condensing capacity to prevent the cooling capacity from being lowered, thereby saving the operating energy.
ドレイン水を放流したロータバケット１３はバケットの自重によって元の姿勢に自動復帰し、室内機３０のドレイン水を受けて貯留することとなる。
The rotor bucket 13 that has drained the drain water automatically returns to its original posture due to its own weight, and receives and stores the drain water of the indoor unit 30.
ところで、図７に示されるように、冷却装置１０が水平方向Ｌに対して傾いて、例えば３°傾いて取付けられている場合、図７の（ａ）に示されるように、ローターバケット１３内にはドレイン水Ｗが偏って貯留され、ローターバケット１３が傾動すると、ドレイン水Ｗは極端に偏って放流され、熱交換器２１のフィン全面を濡らすことができず、冷媒の凝縮能力を補助できないおそれがある。
Incidentally, as shown in FIG. 7, when the cooling device 10 is attached to be inclined with respect to the horizontal direction L, for example, 3 °, as shown in FIG. When the drain water W is stored unevenly and the rotor bucket 13 tilts, the drain water W is discharged extremely unevenly, the entire fin surface of the heat exchanger 21 cannot be wetted, and the refrigerant condensing capacity cannot be assisted. There is a fear.
これに対し、本例の冷却装置では図７の（ｂ）に示されるように、ローターバケット１３内と３つの貯留室１７Ａ、１７Ｂ、１７Ｃに仕切られ、しかも仕切り板１５はローターバケット１３が傾動を開始するドレイン水の水位よりも低い高さに設定されており、冷却装置１０のケーシング１０Ａ内に流入したドレイン水はローターバケット１３の３つの貯留室１７Ａ、１７Ｂ、１７Ｃに分散して貯留され、ローターバケット１３が傾動すると、ドレイン水Ｗは３つの各貯留室１７Ａ、１７Ｂ、１７Ｃから流れ出し、しかもローターバケット１３の側壁板１３Ａの上端縁が鋸歯状に形成されているので、ローターバケット１３から長手方向に分散して放流され、熱交換器２１のフィン全面を確実に濡らすことができ、冷媒の凝縮能力を補助することができる。
On the other hand, in the cooling device of this example, as shown in FIG. 7B, the rotor bucket 13 is partitioned into three storage chambers 17A, 17B, and 17C, and the partition plate 15 tilts the rotor bucket 13. The drain water that has flowed into the casing 10A of the cooling device 10 is dispersed and stored in the three storage chambers 17A, 17B, and 17C of the rotor bucket 13. When the rotor bucket 13 tilts, the drain water W flows out from the three storage chambers 17A, 17B, 17C, and the upper edge of the side wall plate 13A of the rotor bucket 13 is formed in a sawtooth shape. Dispersed in the longitudinal direction and discharged, the entire fin surface of the heat exchanger 21 can be reliably wetted, and the refrigerant condensing capacity is assisted. It is possible.
また、ローターバケット１３の重心がＬ字状金具１４の突辺１４Ｂの下端縁の延長線上に位置せず、例えば図５の図示上方にずれている場合、ローターバケット１３はドレイン水を十分に貯留する前に傾動してしまうおそれがある。本例の冷却装置では重錘１６を取付けているので、上述のようにローターバケット１３の重心が図５の上方にずれている場合には重錘１６を反対方向（図５の矢印参照）に揺動させると、重心をＬ字状金具１４の突辺１４Ｂの下端縁の延長線上に位置させることができるので、ローターバケット１３は十分な量のドレイン水を貯留してから傾動することとなる。
Further, when the center of gravity of the rotor bucket 13 is not located on the extended line of the lower end edge of the projecting side 14B of the L-shaped metal fitting 14, for example, is shifted upward in the drawing of FIG. 5, the rotor bucket 13 sufficiently stores drain water. There is a risk of tilting before doing. Since the weight 16 is attached in the cooling device of this example, when the center of gravity of the rotor bucket 13 is shifted upward in FIG. 5 as described above, the weight 16 is moved in the opposite direction (see the arrow in FIG. 5). By swinging, the center of gravity can be positioned on the extended line of the lower end edge of the projecting side 14B of the L-shaped metal fitting 14, so that the rotor bucket 13 tilts after storing a sufficient amount of drain water. .
また、重錘１６の揺動角度を微調整することによってローターバケット１３の重心位置を変化させることができるので、ローターバケット１３の貯水量を増減させることもできる。
Further, since the center of gravity of the rotor bucket 13 can be changed by finely adjusting the swing angle of the weight 16, the amount of water stored in the rotor bucket 13 can be increased or decreased.
図８及び図９は本発明に係る冷房ドレイン水を用いた室外機の冷却装置の第２の実施形態を示す。本例ではローターバケット１３の重心が図９の図示右方にずれている場合（矢印参照）、Ｌ字状金具１４の突辺１４Ｂを基部１４Ａに対して図９の左方に曲げることによって重心をＬ字状金具１４の突辺１４Ｂの下端縁の延長線上に位置させることができる。なお、本例では仕切り板や重錘を設けてもよく、設けなくてもよく、又ローターバケット１３の側壁板の上端縁を鋸歯状に形成してもよく、形成しなくてもよい。
8 and 9 show a second embodiment of the outdoor unit cooling apparatus using the cooling drain water according to the present invention. In this example, when the center of gravity of the rotor bucket 13 is shifted to the right in the drawing of FIG. 9 (see arrow), the center of gravity is obtained by bending the protruding side 14B of the L-shaped bracket 14 to the left of FIG. Can be positioned on the extension line of the lower end edge of the projecting side 14B of the L-shaped metal fitting 14. In this example, a partition plate or a weight may or may not be provided, and the upper end edge of the side wall plate of the rotor bucket 13 may or may not be formed in a sawtooth shape.
本発明は図１０に示されるように、逆Ｌ字状（コ字状であってもよい）の取付けブラケット４１によって冷却装置１０を室外機２０に取付けるようにした場合にも適用することができる。
As shown in FIG. 10, the present invention can also be applied to the case where the cooling device 10 is attached to the outdoor unit 20 with an inverted L-shaped (may be U-shaped) mounting bracket 41. .
