本体内の両側に蒸発器と凝縮器を配置するものでは、蒸発器より生成されるドレン水を処理するための水受皿を、蒸発器の下部に配置する必要があるが、本体形状を小型化するために水受皿の奥行寸法を小さく抑えようとすると、蒸発器を通過する通過風によりドレン水が本体内あるいは本体外の床面に飛散するため、本体内の機構部品や電装部品などに防水対策を施したり、本体外への飛散防止の対策をする必要があるという課題があり、水受皿の奥行寸法を広げることなく、ドレン水の飛散を防止することが要求されている。   In the case where an evaporator and a condenser are arranged on both sides of the main body, it is necessary to arrange a water tray for processing drain water generated by the evaporator at the lower part of the evaporator, but the body shape is reduced in size. If you try to keep the depth of the water pan small, drain water will splash on the floor inside or outside the main body due to the passing air that passes through the evaporator, so it is waterproof to mechanical parts and electrical parts inside the main body. There is a problem that it is necessary to take countermeasures or to take measures to prevent scattering outside the main body, and it is required to prevent the drain water from scattering without increasing the depth of the water tray.

また、凝縮器と蒸発器とを膨張機能部品としてのキャピラリーチューブにて連結して配管する必要があるが、凝縮器と蒸発器を分離して配置しているので、配管経路が長くなるため、配管途中での固定が不充分であると、キャピラリーチューブの管径が細いために、亀裂が入りやすくガス漏れの恐れがあり、またキャピラリーチューブの表面で発生するドレン水の本体内への漏出対策が必要になるという課題があり、キャピラリーチューブを亀裂のないように保持するとともに、キャピラリーチューブから漏れ出るドレン水を適正に処理できることが要求されている。   In addition, it is necessary to connect the condenser and the evaporator with a capillary tube as an expansion functional part and connect the pipe, but since the condenser and the evaporator are arranged separately, the piping path becomes long. Insufficient fixing in the middle of the piping may cause gas leakage due to the capillary tube diameter being thin, and measures against leakage of drain water generated on the surface of the capillary tube. Therefore, it is required to hold the capillary tube so as not to be cracked and to appropriately treat drain water leaking from the capillary tube.

本発明は上記従来の課題を解決するものであり、水受皿の奥行寸法を拡大しなくても、蒸発器の通過風によるドレン水の飛散を抑制できるとともに、管径が細いキャピラリーチューブを安全に固定でき、キャピラリーチューブの表面で発生するドレン水を確実に水受皿に導くことができる一体型空器調和機を提供することを目的としている。   The present invention solves the above-mentioned conventional problems, and can suppress the scattering of drain water due to the passing air of the evaporator without enlarging the depth dimension of the water pan, and can safely provide a capillary tube with a small tube diameter. An object of the present invention is to provide an integrated air conditioner that can be fixed and can reliably drain water generated on the surface of a capillary tube to a water receiving tray.

本発明の一体型空気調和機は上記目的を達成するために、本体内に設けた圧縮機、蒸発器、凝縮器、キャピラリーチューブからなる冷凍サイクルおよび送風機と、前記キャピラリーチューブに連結された前記蒸発器と前記凝縮器を、前記送風機を挟むようにして支持する支持具と、この支持具に設けた前記蒸発器の下部に配置される水受皿部を有し、前記蒸発器の下端部または前記キャピラリーチューブに付着するドレン水を前記水受皿部に案内するためのドレン水案内手段を設けてなり、前記ドレン水案内手段として水受皿部に包囲壁を設け、この包囲壁は前記蒸発器の両側面で前記水受皿部の上方に支持する一対の支えリブと、前記蒸発器の下方端部に近接または当接して立設する一対の水受けリブとで形成されたものである。 In order to achieve the above object, the integrated air conditioner of the present invention has a refrigeration cycle and a blower comprising a compressor, an evaporator, a condenser, and a capillary tube provided in the main body, and the evaporation connected to the capillary tube. And a condenser that supports the condenser and the condenser so as to sandwich the blower, and a water tray that is disposed at a lower part of the evaporator provided on the support, and the lower end of the evaporator or the capillary tube drain water attached becomes provided drain water guide means for guiding the water pan portion, the surrounding wall is provided in the water receiving tray unit as the drain water guiding means, the surrounding wall is at both sides of the evaporator It is formed by a pair of support ribs that are supported above the water tray portion and a pair of water reception ribs that are erected in proximity to or in contact with the lower end portion of the evaporator.

また他の手段は、蒸発器の前下端部と水受けリブとの間に、微小隙間を形成したものである。   Another means is that a minute gap is formed between the front lower end of the evaporator and the water receiving rib.

また他の手段は、微小隙間の寸法を0.5mm〜1mmとしたものである。   Another means is that the dimension of the minute gap is 0.5 mm to 1 mm.

また他の手段は、蒸発器の後下端部と支えリブまたは水受けリブとの間に隙間を形成しないようにしたものである。   Another means is that no gap is formed between the rear lower end portion of the evaporator and the supporting rib or the water receiving rib.

また他の手段は、前方水受けリブの両端部分をカットして、支えリブとの間に端部通風部を形成したものである。   Another means is that both end portions of the front water receiving rib are cut to form end ventilation portions between the support ribs.

また他の手段は、水受けリブの中央部分をカットして、中央通風部を形成したものである。   Another means is that a central ventilation portion is formed by cutting the central portion of the water receiving rib.

また他の手段は、予備ドレン排水口をドレン排水口の近傍に設けるとともに、水受けリブの中央通風部内に設けたものである。   Another means is that a preliminary drain outlet is provided in the vicinity of the drain outlet and is provided in the central ventilation portion of the water receiving rib.

また他の手段は、ドレン水案内手段として、支持具にキャピラリーチューブを収納する溝部を形成し、この溝部を水受皿部に連通するとともに、この溝部は水受皿部側に傾斜する傾斜勾配を設けたものである。   Another means is a drain water guide means, in which a groove portion for accommodating the capillary tube is formed in the support, and this groove portion communicates with the water receiving tray portion, and this groove portion is provided with an inclined gradient inclined toward the water receiving tray portion side. It is a thing.

Therefore, an integrated air conditioner that can reliably guide the drain water to the water tray is obtained.

本発明によれば、水受皿部の奥行き寸法を拡大することなく、蒸発器またはキャピラリーチューブに付着するドレン水を確実に水受皿部に案内でき、包囲壁により蒸発器の通過風によるドレン水の飛散を抑制して、ドレン水を包囲壁内に導くことができる。 According to the present invention, the drain water attached to the evaporator or the capillary tube can be reliably guided to the water receiving tray portion without increasing the depth dimension of the water receiving tray portion, and the drain water by the passing air of the evaporator is surrounded by the surrounding wall. Splashing can be suppressed and drain water can be guided into the surrounding wall.

また、蒸発器の下端部から落下する直前の水滴を、通過風が微小隙間を通過する気流に乗せて前方水受けリブの後方に落下させることができ、ドレン水の飛散を抑制しつつ、前方水受けリブの前方に落ちないようにして、低温時における氷結を防止することができる。   In addition, the water droplets just before falling from the lower end of the evaporator can be dropped behind the front water receiving rib on the air current passing through the minute gap, while suppressing the scattering of drain water, It is possible to prevent icing at low temperatures by preventing the water receiving rib from falling forward.

また、蒸発器の後端部と支えリブまたは水受けリブとの間に隙間を設けない構成としたので、蒸発器から落下する水滴が通過風により煽られて飛散しても、ドレン水を包囲壁に付着させて水受皿部内に集めることができ、本体内や床面への水漏れを防止することができる。   In addition, since there is no gap between the rear end of the evaporator and the support rib or water receiving rib, even if water drops falling from the evaporator are blown and scattered by the passing air, the drain water is surrounded. It can be attached to the wall and collected in the water receiving tray, and water leakage into the main body and the floor surface can be prevented.

また、端部通風部を通して、通過風が水受皿部の左右端部に留まるドレン水を中央方向に押し出すことで、ドレン排水口へと速やかに押し流すことができ、ドレン水を水受皿部の端部に溜まらないようにして、カビや細菌などの発生を防止することができる。   In addition, by passing through the end ventilation section the drain water where the passing air stays at the left and right ends of the water tray, the drain water can be quickly pushed to the drain outlet, and the drain water can be drained to the end of the water tray. It is possible to prevent the occurrence of mold, bacteria, etc. by preventing it from accumulating in the part.

また、蒸発器5の前端部5bと前方の水受けリブ12aとの間に0.5mm〜1mmの微小隙間tを設け、蒸発器5の後端部5cと支えリブ11a、11bおよび後方の水受けリブ12bとの間には隙間ができないように当接させている。前方の水受けリブ12aの両端部分2ヶ所を10mmほどカットして、支えリブ11a、11bとの間に端部通風部12cを形成するとともに、水受けリブ12a、12bの中央部分を15mm〜20mmカットして中央通風部12dを形成している。水受皿部10の底面は中央通風部12d側に傾斜する傾斜面を形成し、後方の水受けリブ12bの中央通風部12dの底面にドレン排水口13を設けるとともに、予備ドレン排水口14をドレン排水口13の近傍に、かつ中央通風部12d内に立設している。   Further, a minute gap t of 0.5 mm to 1 mm is provided between the front end portion 5b of the evaporator 5 and the front water receiving rib 12a, and the rear end portion 5c of the evaporator 5 and the supporting ribs 11a and 11b and the rear water are provided. It is made to contact | abut so that a clearance gap may not be formed between the receiving ribs 12b. Two end portions of the front water receiving rib 12a are cut by about 10 mm to form an end ventilation portion 12c between the supporting ribs 11a and 11b, and the central portion of the water receiving ribs 12a and 12b is 15 mm to 20 mm. The central ventilation part 12d is formed by cutting. The bottom surface of the water tray portion 10 forms an inclined surface that is inclined toward the central ventilation portion 12d. The drain drain port 13 is provided on the bottom surface of the central ventilation portion 12d of the rear water receiving rib 12b, and the preliminary drain drain port 14 is drained. It is erected in the vicinity of the drain port 13 and in the central ventilation portion 12d.

また、ダンパー17を送風機8の風下側に備えることにより、冷風運転のときは、ダンパー17を一方に回動することにより、冷風を分離して吹出口2bから前方に冷風を吹き出し、乾燥風を吹き出す除湿運転のときは、ダンパー17を他方に回動することにより、冷風を温風と混合して吹出口2aから乾燥風を吹き出すことができる。なお、水受皿部10からのドレン水を溜める排水タンク16を、ドレン排水口13の下方に着脱可能に設けている。   In addition, by providing the damper 17 on the leeward side of the blower 8, during cold wind operation, the damper 17 is rotated in one direction to separate the cold wind and blow the cool wind forward from the outlet 2 b, and the dry wind During the dehumidifying operation, the damper 17 is rotated to the other, so that the cool air can be mixed with the warm air and the dry air can be blown out from the air outlet 2a. In addition, the drain tank 16 which accumulates drain water from the water tray part 10 is provided in the downward direction of the drain drain port 13 so that attachment or detachment is possible.

上記構成において、冷風運転を行う場合は、図1に示すようにダンパー17を実線の位置に回動することにより、吸込口1a、1bから室内空気を吸込み、蒸発器5、凝縮器6を通過したそれぞれの風は、上部にある吹出口2aから温風が吹き出されるとともに、前方にある吹出口2bから冷風が吹き出されるので、使用者が吹出口2bの前方に位置することにより、除湿された冷風を受けることができる。   In the above configuration, when cold air operation is performed, the damper 17 is rotated to the position of the solid line as shown in FIG. 1 to suck indoor air from the suction ports 1a and 1b and pass through the evaporator 5 and the condenser 6. Since each of the winds blows warm air from the air outlet 2a at the top and cool air from the air outlet 2b at the front, the user is dehumidified by being positioned in front of the air outlet 2b. Can receive the cold air.

除湿運転を行う場合は、図1に示すようにダンパー17を破線の位置に移動して風路が切り換り、温風と冷風を混合した乾燥風が上部の吹出口2aから吹き出すことができる。   When performing the dehumidifying operation, the damper 17 is moved to the position of the broken line as shown in FIG. 1, the air path is switched, and the dry air mixed with the hot air and the cold air can be blown out from the upper outlet 2a. .

また、蒸発器5の下部に配置される水受皿部10に包囲壁20を設け、包囲壁20の一部を構成する前方の水受けリブ12aと蒸発器5の前端部5bとの間に0.5mm〜1mmの微小隙間tを形成しているので、蒸発器5の通過風18が微小隙間tを通るときに、蒸発器5の前端部5bに付着するドレン水滴を、水受けリブ12aの後方の包囲壁20内に落とすことができ、ドレン水の本体3内への飛散を抑制するとともに、水受けリブ12aの前方に落ちないようにすることで、低温時における水受けリブ12aの前方での氷結を防ぐことができ、ドレン排水口13にドレン水を速やかに導くことができる。   Further, the surrounding wall 20 is provided in the water receiving tray portion 10 disposed in the lower part of the evaporator 5, and 0 is placed between the front water receiving rib 12 a constituting a part of the surrounding wall 20 and the front end portion 5 b of the evaporator 5. Since the minute gap t of 5 mm to 1 mm is formed, when the passing air 18 of the evaporator 5 passes through the minute gap t, the drain water droplets adhering to the front end portion 5b of the evaporator 5 can be removed from the water receiving rib 12a. The water can be dropped into the surrounding wall 20 at the rear, and it is possible to prevent the drain water from scattering into the main body 3 and to prevent the water from falling to the front of the water receiving rib 12a. Freezing can be prevented, and drain water can be promptly guided to the drain outlet 13.

また、蒸発器5の後端部5cと、支えリブ11a、11bおよび後方の水受けリブ12bとの間に隙間を生じないように配置することで、蒸発器5から落下するドレン水滴を通過風18により煽られて飛散しても、ドレン水を支えリブ11a、11bおよび後方の水受けリブ12bに付着させて、ドレン排水口13に導くことができ、ドレン水が本体3外へ飛び出したり、本体3内の送風機8などに付着して劣化するような弊害を未然に防止することができる。   Further, by arranging the rear end portion 5c of the evaporator 5 so as not to create a gap between the support ribs 11a and 11b and the rear water receiving rib 12b, the drain water droplets falling from the evaporator 5 can be passed through. Even if it is beaten and scattered by 18, drain water can be attached to the supporting ribs 11 a, 11 b and the rear water receiving rib 12 b and guided to the drain outlet 13, and the drain water can jump out of the main body 3, It is possible to prevent adverse effects such as adhering to the blower 8 in the main body 3 and deteriorating.

また、前方の水受けリブ12aの両端部分をカットして、支えリブ11a、11bとの間に端部通風部12cを形成することにより、蒸発器5の通過風18が端部通風部12cを通過するときに、水受皿部10上のドレン水を中央方向に押し流すことができ、ドレン水が水受皿部10上に溜まることなくドレン排水口13に向けて導くことができる。   Further, both end portions of the front water receiving rib 12a are cut to form the end ventilation portion 12c between the support ribs 11a and 11b, so that the passing air 18 of the evaporator 5 causes the end ventilation portion 12c. When passing, drain water on the water receiving tray 10 can be pushed away in the central direction, and the drain water can be guided toward the drain outlet 13 without accumulating on the water receiving tray 10.

また、水受けリブ12a、12bの中央部分をカットして、中央通風部12dを形成することにより、中央通風部12dを通過した通過風18が、ドレン排水口13内をも通過させることができ、ドレン排水口13付近に滞留しやすいドレン水の排水を促すことができ、滞留した水分が低温時に氷結するのを防止することができる。   Further, by cutting the central portions of the water receiving ribs 12a and 12b to form the central ventilation portion 12d, the passing air 18 that has passed through the central ventilation portion 12d can also pass through the drain discharge port 13. Further, drainage of drain water that tends to stay in the vicinity of the drain discharge port 13 can be promoted, and the retained water can be prevented from freezing at low temperatures.

また、予備ドレン排水口14をドレン排水口13の近傍かつ後部の水受けリブ12bの中央通風部12d内に設けることで、ドレン排水口13がゴミや氷結等で詰まった時でも、予備ドレン排水口14を使用してドレン水を排水タンク16に回収することができ、また突設する予備ドレン排水口14の周りに通風して、ゴミ等が付着したり堆積しないようにすることができる。   Further, by providing the auxiliary drain outlet 14 in the vicinity of the drain outlet 13 and in the central ventilation portion 12d of the rear water receiving rib 12b, even when the drain outlet 13 is clogged with dust or icing, etc. Drain water can be collected in the drain tank 16 using the port 14, and air can be ventilated around the preliminarily drained drain drain port 14 to prevent dust or the like from adhering or accumulating.

(実施の形態2)
図1〜図4に示すように、支持具9は蒸発器5と凝縮器6を分離して載置するとともに、蒸発器5と凝縮器6を接続するキャピラリーチューブ7を保護チューブ7aを介して、支持具9に形成した溝部15に収納している。すなわち、外形寸法2.1mmのキャピラリーチューブ7の外周に、外形寸法d=6mmの保護チューブ7aを付設して保護キャピラリーチューブ7Aとし、支持具9に保護キャピラリーチューブ7Aを収納するための断面U字状の溝部15を形成している。溝部15の溝幅寸法wを5mmとして、保護キャピラリーチューブ7Aの外形寸法d(=6mm)より小とし、溝部15の深さ寸法hを7mm〜20mmとして保護チューブの外形寸法d(=6mm)より大としている。
(Embodiment 2)
As shown in FIGS. 1 to 4, the support 9 separates the evaporator 5 and the condenser 6 and places the capillary tube 7 connecting the evaporator 5 and the condenser 6 via the protective tube 7a. The groove 9 is formed in the support 9. That is, a protective tube 7a having an outer dimension d = 6 mm is attached to the outer periphery of the capillary tube 7 having an outer dimension of 2.1 mm to form a protective capillary tube 7A, and a U-shaped cross section for housing the protective capillary tube 7A in the support 9 A groove 15 is formed. The groove width dimension w of the groove 15 is 5 mm, which is smaller than the outer dimension d (= 6 mm) of the protective capillary tube 7A, and the depth dimension h of the groove 15 is 7 mm to 20 mm, from the outer dimension d (= 6 mm) of the protective tube. It ’s big.

溝部15の全体形状は側方から見て、水受皿部10部側に傾斜して連通する傾斜勾配を設けるとともに、溝部15の両端付近でそれぞれ下方に曲がる円弧形状としている。   The overall shape of the groove portion 15 is an arc shape that is inclined downwardly in the vicinity of both ends of the groove portion 15 while being provided with an inclined gradient in communication with the water tray portion 10 portion side when viewed from the side.

上記構成において、支持具9に形成した溝部15を蒸発器5の最下端より約7mm高い位置に設け、蒸発器5から引き出したキャピラリーチューブ7を屈曲状態で配管して溝部15で固定する。このとき、キャピラリーチューブ7はいったん円状に巻回され、さらに水受皿部10の上方に懸架されるときに、途中で傾斜の向きを下方向から上方向に変えて、溝部15に収納する。このように、キャピラリーチューブ7が水受皿部10の上方に懸架されるときには、下がり勾配から上り勾配に配管にすることで、途中で水切りができ、蒸発器5に近い部分で発生するドレン水を水受皿部10に確実に落とすことができる。   In the above configuration, the groove 15 formed in the support 9 is provided at a position approximately 7 mm higher than the lowermost end of the evaporator 5, and the capillary tube 7 drawn out from the evaporator 5 is piped in a bent state and fixed by the groove 15. At this time, when the capillary tube 7 is once wound in a circular shape and is further suspended above the water receiving tray 10, the capillary tube 7 is accommodated in the groove portion 15 while changing the direction of inclination from the downward direction to the upward direction. In this way, when the capillary tube 7 is suspended above the water receiving tray 10, draining water generated in a portion near the evaporator 5 can be drained on the way by piping from the downward gradient to the upward gradient. It can be reliably dropped on the water tray 10.

また、溝部15に収納されるキャピラリーチューブ7は、保護チューブ7aを巻いた保護キャピラリーチューブ7Aの状態として、溝部15の蒸発器5側の端部は水受皿部10に連通して設けるとともに、溝部15は水受皿部10に近い範囲では、水受皿部10方向に5度の下り勾配とした傾斜勾配を設けている。これにより、保護キャピラリーチューブ7Aで発生するドレン水を確実に水受皿部10へ戻すことができ、さらに保護チューブ7aで覆われたキャピラリーチューブ7は、接触する空気量自体を減らすことができるので、発生するドレン水の量を減少することができる。   Further, the capillary tube 7 accommodated in the groove portion 15 is provided as a state of the protective capillary tube 7A around which the protective tube 7a is wound, and the end portion on the evaporator 5 side of the groove portion 15 is provided in communication with the water receiving tray portion 10, and the groove portion In the range close to the water tray 10, 15 is provided with a slope of 5 degrees downward in the direction of the water tray 10. As a result, the drain water generated in the protective capillary tube 7A can be reliably returned to the water receiving tray 10, and the capillary tube 7 covered with the protective tube 7a can reduce the amount of air contacted itself. The amount of drain water generated can be reduced.

また、溝部15の幅寸法wは、弾性のある保護チューブ7aを付設したキャピラリーチューブ7Aの外形dより小としているので、管径が細いキャピラリーチューブ7を傷つけることなく、保護チューブ7aと合成樹脂製の溝部15との摩擦力により確実に固定できる。また、溝部15の深さ寸法hを保護キャピラリーチューブ7Aの外形dより大としているので、保護キャピラリーチューブ7Aが溝部15内の上部に保持されることにより、U字状の溝部15の底面が連通状態となり、連通する底面を伝わらせてドレン水を水受皿部10に導くことができる。   Further, since the width dimension w of the groove 15 is smaller than the outer diameter d of the capillary tube 7A provided with the elastic protective tube 7a, the protective tube 7a and the synthetic resin are made without damaging the capillary tube 7 having a small tube diameter. It can be reliably fixed by the frictional force with the groove 15. Further, since the depth dimension h of the groove portion 15 is larger than the outer shape d of the protective capillary tube 7A, the bottom surface of the U-shaped groove portion 15 communicates with the protective capillary tube 7A being held in the upper portion of the groove portion 15. It becomes a state, and the drain water can be guided to the water tray 10 by being transmitted through the communicating bottom surface.

また、溝部15の全体形状を支持具9の両端付近で、曲率半径10mm〜20mmの下方に曲がる円弧形状とすることで、保護キャピラリーチューブ7Aを曲げて配管するときの成型冶具の必要がなく、溝部15に沿った形状に容易に曲げることができ、管径が細いキャピラリーチューブ7を傷つけることなく確実に固定することができる。   Further, by forming the entire shape of the groove portion 15 in an arc shape that is bent downward with a curvature radius of 10 mm to 20 mm in the vicinity of both ends of the support 9, there is no need for a molding jig when bending and piping the protective capillary tube 7A. It can be easily bent into a shape along the groove 15 and can be securely fixed without damaging the capillary tube 7 having a small tube diameter.

本発明は、蒸発器の下端部またはキャピラリーチューブにドレン水案内手段を設けて、水受皿部の奥行き寸法を大きくせずに、通過風による蒸発器からのドレン水の本体内への飛散を抑制することができるものであり、エアコンなどの空調機器の用途にも適用できる。   The present invention provides the drain water guide means at the lower end of the evaporator or the capillary tube to prevent the drain water from splashing into the main body from the evaporator without increasing the depth of the water tray. It can be applied to applications of air conditioning equipment such as air conditioners.
