Description

本発明は、ドラム式洗濯乾燥機などの機器に搭載され、循環空気を空調する空調ユニットに関するものである。   The present invention relates to an air conditioning unit that is mounted on a device such as a drum-type washing and drying machine and air-conditions circulating air.
このような空調ユニットは、ドラム式洗濯乾燥機に搭載するものとして既に知られている(例えば、特許文献1参照。)。図14に概略的に示す本発明の実施の形態に係るドラム式洗濯乾燥機1を参照して説明すると、空調ユニット39は、ドラム式洗濯乾燥機1内に、その水槽3の背部のデッドスペースなどを利用して内蔵され、送風ファン15を持った循環送風経路5の途中に接続される。これにより、循環送風経路5は送風ファン15の駆動により、水槽3内の空気を吸引して排気し、空調ユニット39にその吸引導入口391から導入して蒸発器31による除湿、凝縮器32による加熱に供して乾燥した高温空気とした後、吸引排出口392から排出して水槽3側に送風して水槽3内に戻し、回転ドラム2内の洗濯物を乾燥させることを繰り返し、洗濯工程やすすぎ工程後の乾燥工程を実行する。   Such an air conditioning unit is already known to be mounted on a drum-type washing / drying machine (see, for example, Patent Document 1). Referring to the drum type washing and drying machine 1 according to the embodiment of the present invention schematically shown in FIG. 14, the air conditioning unit 39 includes a dead space in the back of the water tank 3 in the drum type washing and drying machine 1. Etc., and is connected in the middle of the circulation air passage 5 having the air blowing fan 15. Thereby, the circulation air flow path 5 sucks and exhausts the air in the water tank 3 by driving the blower fan 15, introduces the air into the air conditioning unit 39 from the suction introduction port 391, dehumidifies by the evaporator 31, and by the condenser 32. After heating to dry high-temperature air, it is discharged from the suction outlet 392, blown toward the water tank 3 and returned to the water tank 3, and the laundry in the rotating drum 2 is repeatedly dried to facilitate the washing process. A drying step after the rinsing step is performed.
このために、空調ユニット39は、本実施の形態を示す図5を参照して、ユニットケース38内に、蒸発器31、凝縮器32を設置する、吸引導入口391と吸引排出口392との間の通風路393と、蒸発器31および凝縮器32に冷媒を循環させる圧縮機37を収容する収容域394と、を区画壁によって区画している。この区画部において、従来、本実施の形態では採用していないシール部材により、通風路393と収容域394との間をシールし、それぞれの独立性を確保している。   For this purpose, the air conditioning unit 39 refers to FIG. 5 showing the present embodiment, and includes a suction inlet 391 and a suction outlet 392 in which the evaporator 31 and the condenser 32 are installed in the unit case 38. The ventilation path 393 between them and the accommodation area 394 for accommodating the compressor 37 for circulating the refrigerant in the evaporator 31 and the condenser 32 are partitioned by a partition wall. In this partition part, the space between the ventilation path 393 and the accommodation area 394 is sealed by a sealing member that has not been conventionally employed in the present embodiment to ensure the independence of each.
この故に、通風路393および収容域394双方の底部に万一にも溜まることのある水を排水するのに、それぞれで異なった排水構造を設けている。具体的には通風路393では引圧を利用した空気流入に対する逆止作用をなす排水弁機構を設け、収容域394では底部に単なる排水口を設けている。この排水口は、圧縮機に接続される蒸発器31からの戻り配管である低温配管からの定常的な結露水の排出にも機能し、結露水が溜まらないようにできる。   For this reason, different drainage structures are provided for draining water that may accumulate in the bottom of both the ventilation path 393 and the accommodation area 394. Specifically, the ventilation path 393 is provided with a drain valve mechanism that performs a check action against air inflow using suction pressure, and the housing area 394 is provided with a simple drain port at the bottom. This drainage port also functions to discharge dew condensation water from a low temperature pipe that is a return pipe from the evaporator 31 connected to the compressor, so that the dew condensation water does not accumulate.
また、ユニットケース38は、通風路393の収容域394と区画した複雑な構造上、3つの分割部材によって構成し、ユニットケース38内の前記区画境界部でのシールに加え、各分割部材間がケース外面に臨んで形成する割線間にもシール部材を挟持してユニットケース38の内外をエアタイトするようにしている。
特開2008−79861号公報
In addition, the unit case 38 is constituted by three divided members because of the complicated structure partitioned from the housing area 394 of the ventilation path 393, and in addition to the seal at the partition boundary in the unit case 38, the space between the divided members is A seal member is also sandwiched between secant lines formed facing the outer surface of the case so that the inside and outside of the unit case 38 is airtight.

しかし、従来のように複数箇所にシール構造を付与するのでは、その形状の複雑さも手伝ってコスト高になるし、シール部材は耐用年数が製品の寿命よりも短いことが多く、交換対象部品となるので、ランニングコストにも影響する。特に、区画部でのシールは、蒸発器31や凝縮器32と圧縮機37との配管連結のために蒸発器31、凝縮器32の端部が収容域394側に臨んだ部分のまわりを含み、シール部材が蒸発器31や凝縮器32からの熱影響により劣化しやすく寿命が短くなる。また、シール構造を介した区画上、通風路393および収容域394間での共通した排水系が構成できない不便がある。   However, providing a seal structure at multiple locations as in the past increases the cost by helping with the complexity of the shape, and the seal member often has a shorter service life than the product life. Therefore, it will affect the running cost. In particular, the seal at the partition portion includes around the portion where the end portions of the evaporator 31 and the condenser 32 face the storage area 394 for connecting the evaporator 31 and the condenser 32 to the compressor 37. The seal member is liable to deteriorate due to the heat effect from the evaporator 31 and the condenser 32, and the service life is shortened. In addition, there is an inconvenience that a common drainage system between the ventilation path 393 and the accommodation area 394 cannot be configured on the section through the seal structure.
本発明の目的は、圧縮機の収容域と蒸発器、凝縮器を設置する通風路とのシール構造を省略化して、製品コスト、ランニングコスト共に低減する空調ユニットを提供することにある。   An object of the present invention is to provide an air conditioning unit that eliminates a sealing structure between a compressor housing area and an air passage for installing an evaporator and a condenser, thereby reducing both product cost and running cost.
上記目的を達成するための本発明の空調ユニットは、循環空気の吸引導入口および循環空気の吸引排出口を持ったユニットケース内に、前記吸引導入口から前記吸引排出口への通風路途中に位置して循環空気を除湿し乾燥させる蒸発器および凝縮器と、これら蒸発器および凝縮器に冷媒を循環させる圧縮機と、を内蔵した空調ユニットにおいて、前記ユニットケースは、複数の分割部材からなり、各分割部材どうしが前記ユニットケースの外面に臨んでなす割線間にシール部材を連続に挟持して前記ユニットケースの内外をエアタイトし、前記ユニットケースの水溜り部の外壁に、溜り水によって開かれて溜まり水を排水させるが外気の吸引を阻止する排水機構を設けたことを1つの特徴としている。   In order to achieve the above object, an air conditioning unit of the present invention is provided in a unit case having a circulating air suction inlet and a circulating air suction outlet in the middle of a ventilation path from the suction inlet to the suction outlet. In an air conditioning unit including an evaporator and a condenser that are positioned to dehumidify and dry the circulating air, and a compressor that circulates the refrigerant in the evaporator and the condenser, the unit case includes a plurality of divided members. In addition, the sealing member is continuously sandwiched between the dividing lines formed by the divided members facing the outer surface of the unit case to air-tighten the inside and outside of the unit case, and the outer wall of the water reservoir portion of the unit case is opened by the accumulated water. One feature is that a drainage mechanism is provided that drains accumulated water and prevents outside air from being sucked.
このような構成では、圧縮機の駆動によって蒸発器、凝縮器が冷媒の循環を受けて働き、ユニットケースの吸引排出口側に吸引力が働くことで、この吸引力が通風路を通じユニットケースの吸引導入口にも及び、吸引導入口から通風路を通って吸引排出口から排出される循環空気の流れができ、循環空気は通風路途中にある蒸発器、凝縮器に通して除湿および加熱し乾燥した高温空気として連続に送り出せる。ユニットケースは複数の分割部材で構成されるが、それら各分割部材がユニットケースの外面に臨んでなす割線間にシール材を挟持してユニットケースの内外をエアタイトする簡単なシール構造で、吸引導入口から吸引排出口への通風路に例え圧縮機の収容域側との連通があっても吸引作用が積極的に及ばず空気溜まりになる収容域の影響なく、吸引空気の循環と除湿および加熱との機能を確保することができる。また、互いの連通を利用して収容域、通風路の別なく、万が一の場合の急な水溜まりには、ユニットケースの水溜り部に設けた排水機構が、溜り水によって開かれて溜まり水を排水させることで対応しながら、外気の吸引は阻止して循環空気を導入して熱交換し排出する機能を確保するようにできる。   In such a configuration, the evaporator and condenser work by receiving the circulation of the refrigerant by driving the compressor, and the suction force acts on the suction / discharge port side of the unit case. The circulating air can also flow from the suction inlet to the suction inlet through the ventilation path, and the circulating air is dehumidified and heated through an evaporator and a condenser in the middle of the ventilation path. Can be sent continuously as dry hot air. The unit case is made up of a plurality of divided members, but with a simple seal structure that airtights the inside and outside of the unit case by sandwiching a sealing material between the dividing lines formed by each of the divided members facing the outer surface of the unit case. Even if there is communication with the compressor housing area, such as the air passage from the mouth to the suction outlet, the suction action does not reach positively and the suction air is circulated, dehumidified, and heated without being affected by the housing area where air is trapped. And the function can be secured. In addition, in the event of a sudden water pool regardless of the storage area or ventilation path using the mutual communication, the drainage mechanism provided in the pool of the unit case is opened by the pooled water and the pooled water is drained. While responding by draining, it is possible to prevent the outside air from being sucked and to secure the function of introducing the circulating air and exchanging and discharging the heat.
本発明の空調ユニットは、また、循環空気の吸引導入口および循環空気の吸引排出口を持ったユニットケース内に、前記吸引導入口から前記吸引排出口への通風路途中に位置して循環空気を除湿し乾燥させる蒸発器および凝縮器と、これら蒸発器および凝縮器に冷媒を循環させる圧縮機と、を内蔵した空調ユニットにおいて、前記ユニットケースは、前記通風路と前記圧縮機の収容域とをシール構造なく区画する複数の分割部材からなり、各分割部材どうしがユニットケースの外面に臨んでなす割線間にシール部材を連続に挟持して前記ユニットケースの内外をエアタイトし、ユニットケースの水溜り部の外壁に溜り水によって開かれて溜まり水を排水させるが外気の吸引を阻止する弁機構を設けたことを別の特徴としている。   The air conditioning unit of the present invention is also provided in a unit case having a circulating air suction inlet and a circulating air suction outlet, and is located in the middle of a ventilation path from the suction inlet to the suction outlet. In an air conditioning unit including an evaporator and a condenser for dehumidifying and drying the refrigerant, and a compressor for circulating a refrigerant in the evaporator and the condenser, the unit case includes the ventilation path and the compressor accommodating area. Is formed of a plurality of divided members that are divided without sealing structure, and the sealing member is continuously sandwiched between the dividing lines formed by the divided members facing the outer surface of the unit case to air tight the inside and outside of the unit case. Another feature is that a valve mechanism is provided on the outer wall of the reservoir so as to be opened by the accumulated water to drain the accumulated water but prevent the outside air from being sucked.
このような構成では、圧縮機の駆動によって蒸発器、凝縮器が冷媒の循環を受けて働き、ユニットケースの吸引排出口側に吸引力が働くことで、この吸引力が通風路を通じユニットケースの吸引導入口にも及び、吸引導入口から通風路を通って吸引排出口から排出される循環空気の流れができ、循環空気は通風路途中にある蒸発器、凝縮器に通して除湿および加熱し乾燥した高温空気として連続に送り出せる。ユニットケースは前記通風路と前記圧縮機の収容域とをシール構造なく区画する複数の分割部材で構成されるが、それら各分割部材がユニットケースの外面に臨んでなす割線間にシール材を挟持してユニットケースの内外をエアタイトし、吸引導入口から吸引排出口への通風路において、圧縮機の収容域側との連通が双方の区画部にあっても、その区画効果が合わさって収容域に吸引作用がほとんど及ばなくして、吸引空気の循環と除湿および加熱との機能をより確実に確保することができる。また、互いの連通を利用して収容域、通風路の別なく、万が一の場合の急な水溜まりには、ユニットケースの水溜り部に設けた排水機構が、溜り水によって開かれて溜まり水を排水させることで対応しながら、外気の吸引は阻止して循環空気を導入して熱交換し排出する機能を確保するようにできる。   In such a configuration, the evaporator and condenser work by receiving the circulation of the refrigerant by driving the compressor, and the suction force acts on the suction / discharge port side of the unit case. The circulating air can also flow from the suction inlet to the suction inlet through the ventilation path, and the circulating air is dehumidified and heated through an evaporator and a condenser in the middle of the ventilation path. Can be sent continuously as dry hot air. The unit case is composed of a plurality of divided members that divide the ventilation path and the storage area of the compressor without a sealing structure. The sealing material is sandwiched between the dividing lines formed by the divided members facing the outer surface of the unit case. Then, the inside and outside of the unit case is airtight, and even in the ventilation path from the suction introduction port to the suction discharge port, even if the communication with the storage area side of the compressor is in both partition parts, the partition effect is combined and the storage area Therefore, the functions of circulation of the suction air, dehumidification and heating can be ensured more reliably. In addition, in the event of a sudden water pool regardless of the storage area or ventilation path using the mutual communication, the drainage mechanism provided in the pool of the unit case is opened by the pooled water and the pooled water is drained. While responding by draining, it is possible to prevent the outside air from being sucked and to secure the function of introducing the circulating air and exchanging and discharging the heat.
ここに、前記ユニットケースは、2つの分割部材からなるものとすることができる。
このような構成では、上記に加え、さらに、部材点数、組立工数、シール構造部がさらに低減する。
Here, the unit case may be composed of two divided members.
In such a configuration, in addition to the above, the number of members, the number of assembly steps, and the seal structure portion are further reduced.
上記において、さらに、前記弁機構は、水溜まり部の外壁に設けられた排水口と、この排水口をユニットケース内の引圧によって外側から閉じる逆止弁と、からなることを特徴とすることができる。   In the above, the valve mechanism further includes a drain port provided on the outer wall of the water reservoir, and a check valve that closes the drain port from the outside by a pulling pressure in the unit case. it can.
このような構成では、上記に加え、さらに、逆止弁は、ユニットケース内に引圧が働く動作時のみ、その引圧により水溜り部の外壁に設けられ排水口を閉じて気密性よく外気を遮断して空調ユニットの機能を保全しながら、万が一の場合の多量の水溜りには押し開かれて排水し、非動作時は特に閉まる必要はなく、閉じ習性のない簡単なフラップ式の弁片にて実現できる。   In such a configuration, in addition to the above, the check valve is provided on the outer wall of the water reservoir portion by the pulling pressure only during the operation in which the pulling pressure is applied in the unit case, and closes the drain port so that the outside air is airtight. While maintaining the function of the air conditioning unit by shutting off, it is pushed open to drain a large amount of water in the event of an emergency, and it is not necessary to close when not in operation, and it is a simple flap type valve that does not close It can be realized with a piece.
上記において、さらに、前記ユニットケースは、長手方向の一端の天井壁の後部に前記吸引導入口が、他端の端部壁に前記吸引排出口が設けられたほぼ長方体形状をなし、前記圧縮機は、前記ユニットケース内の前部寄りの収容域に収容され、この前記収容域と、この収容域に対し前記ユニットケース内の後部側および他端部側に広がる前記通風路と前記ユニットケースをなす分割部材から延びる区画壁によって区画され、前記蒸発器、凝縮器よりなる熱交換部は、前記ユニットケースの長手方向に対向し合う区画壁と前記端部壁との間の熱交換域を前後の吸引導入側および吸引排出側に仕切って設けられ、前記吸引導入口は、前記ユニットケースの前記熱交換域の天井壁よりも高く上向きに開口し、かつ平面視して前記収容域の後部側上部にオーバーラップする位置から前記通風路における前記熱交換域の前記ユニットケース一端側に前記収容域の後部へ拡張した一端側後部域上に及ぶ大きさで設けられ、前記通風路は、前記吸引導入口の基部開口から前記一端側後部域に滑らかに繋がって循環空気を下向きに案内する縦向き湾曲域と、前記熱交換域の吸引導入側を、前記吸引導入口の高さ未満でこの吸引導入口から前記ユニットケースの他端側に掛けて上方に拡張した後部上向き拡張域と、を備えていることを特徴とすることができる。   In the above, the unit case further has a substantially rectangular shape in which the suction inlet is provided at the rear of the ceiling wall at one end in the longitudinal direction, and the suction outlet is provided at the end wall at the other end. The compressor is housed in a housing area closer to the front in the unit case, the housing area, and the ventilation path and the unit that extend to the rear side and the other end side in the unit case with respect to the housing area. A heat exchange section that is partitioned by a partition wall that extends from a dividing member that forms a case, and that includes the evaporator and the condenser, is a heat exchange area between the partition wall and the end wall facing each other in the longitudinal direction of the unit case. Is divided into a front and rear suction introduction side and a suction discharge side, and the suction introduction port is opened upward and higher than the ceiling wall of the heat exchange area of the unit case, and in plan view, Rear side upper part Provided from the overlapping position to the one end side of the unit case of the heat exchange area in the ventilation path on the one end side rear area extended to the rear part of the accommodation area, and the ventilation path is the suction inlet A vertical curved region that smoothly connects the rear end region of the one end side to the rear region of the one end side and guides the circulating air downward, and the suction introduction side of the heat exchange region is less than the height of the suction introduction port. To the other end side of the unit case, and a rear upward extension region extended upward.
このような構成では、上記に加え、さらに、ユニットケースの長手方向一端の天井壁の後部に設けた吸引導入口と、他端の端部壁に設けた吸引排出口との間の、ユニットケースの一端の前部寄りで圧縮機を収容して区画壁で区画された収容域を除く、ユニットケースの長手方向ほぼ一杯に利用した通風路にて、吸引導入口から導入する循環空気を、圧縮機の収容域横の熱交換域からユニットケースの一端側に外れた一端側後部域と、熱交換域の後部から上部に外れた後部上向き拡張部とに受け入れて、熱交換域の後部となる吸引導入側で合流させながら、熱交換域に設置された熱交換部の蒸発器、凝縮器による均等な通過抵抗による充満効果も手伝って、それら蒸発器、凝縮器のほぼ全域を後部から前部へ偏りなくほぼ均等に通過される熱交換流を生成することができる。特に、吸引導入口が平面視して前記圧縮機の収容域の後部側上にオーバーラップする位置から前記通風路における一端側後部域上に及ぶ大きさであることにより循環空気の導入風量を高めながら、吸引導入口よりも前後幅の小さな一端側後部域への流れは絞られるものの、縦向き湾曲路による案内で乱れや圧損なくスムーズに導入させて熱交換域の後部吸引導入側に向かわせられるのに併せ、前記絞りを受ける分だけ、導入空気が吸引導入口から後部上向き拡張域側に流れ込みやすくすることができる。   In such a configuration, in addition to the above, the unit case between the suction inlet provided in the rear part of the ceiling wall at one end in the longitudinal direction of the unit case and the suction outlet provided in the end wall at the other end Compress the circulating air introduced from the suction inlet in the ventilation path that is used almost fully in the longitudinal direction of the unit case, excluding the storage area partitioned by the partition wall by storing the compressor near the front of one end Receiving in the rear end area on one end of the unit case from the heat exchange area next to the machine's housing area, and the rear upward extension extending from the rear to the upper part of the heat exchange area, it becomes the rear part of the heat exchange area While converging on the suction introduction side, the evaporator and condenser of the heat exchange section installed in the heat exchange area also helped with the filling effect due to the uniform passage resistance, so that almost the entire area of the evaporator and condenser was moved from the rear to the front. Heat exchange that passes almost evenly It is possible to generate the flow. In particular, the introduction air volume of the circulating air is increased by the size from the position where the suction introduction port overlaps on the rear side of the housing area of the compressor in plan view to the one end side rear area of the ventilation path. However, although the flow to the rear part on the one end side, which is smaller in width than the suction introduction port, is restricted, it is smoothly introduced without any disturbance or pressure loss by the guide through the longitudinally curved path, and directed toward the rear suction introduction side of the heat exchange area. At the same time, the intake air can easily flow from the suction inlet toward the rear upward expansion region by the amount of the restriction.
上記において、さらに、前記弁機構は、前記圧縮機の前記収容域の底部と、通風路の底部とを前記水溜り部としてそれら双方に設けられていることを特徴とすることができる。このような構成では、上記に加え、さらに、圧縮機の収容域と通風路とは、シール構造がなく連通していることで、通風路側から収容域側に急な水溜まりが及んでも高低関係などで通風路側からの排水が望めないようなことに対し収容域側で対応できるし、双方共に引圧が働くことを利用した弁機構にて対応することができる。   In the above, the valve mechanism can be further characterized in that the bottom part of the accommodating area of the compressor and the bottom part of the ventilation path are provided in both as the water pool part. In such a configuration, in addition to the above, the storage area of the compressor and the ventilation path are connected to each other without a sealing structure, so that even if a sudden water pool extends from the ventilation path side to the storage area side, the height relationship is high. For example, it is possible to cope with the fact that drainage from the ventilation path side cannot be expected by the accommodation area side, and it is possible to cope with both by a valve mechanism utilizing the fact that the suction pressure works.
本発明の空調ユニットの1つの特徴によれば、ユニットケースを構成する複数の分割部材がユニットケースの外面に臨んでなす割線間でシールしてユニット内外をエアタイトした簡単なシール構造で、通風路の圧縮機の収容域側との連通の影響なく吸引空気の循環と除湿および加熱との機能を確保しながら、互いの連通を利用して収容域、通風路の別なく、通常排水系はもとより、万が一の場合の急な水溜まりには、ユニットケースの水溜り部に設けた排水機構によって、循環空気を導入して熱交換し排出する機能を確保しながら対応でき、シール箇所が少ない分だけ、部品点数、組立工数、および部品交換数が低減するので、製品コストおよびランニングコストが共に低減する。   According to one feature of the air conditioning unit of the present invention, a simple sealing structure in which a plurality of divided members constituting the unit case are sealed between the dividing lines formed facing the outer surface of the unit case and the inside and outside of the unit are airtight, and the ventilation path While ensuring the functions of suction air circulation, dehumidification and heating without the influence of communication with the storage area side of the compressor, using the mutual communication, regardless of the storage area and ventilation path, the normal drainage system as well In the unlikely event of a sudden puddle, the drainage mechanism provided in the puddle part of the unit case can be used while ensuring the function of introducing and exchanging heat by circulating air, and the amount of seals is small, Since the number of parts, the number of assembly steps, and the number of parts replacement are reduced, both the product cost and the running cost are reduced.
本発明の空調ユニットの別の特徴によれば、1つの特徴に加え、さらに、通風路と圧縮機の収容域とをシール構造なく区画して、収容域へは吸引作用がほとんど及ばなくして吸引空気の循環と除湿および加熱との機能をより確実に確保して性能を高めながら、圧縮機の収容域および通風路の少しの連通にて収容域、通風路の別なく、通常排水系を共通にすることができる。   According to another feature of the air-conditioning unit of the present invention, in addition to one feature, the ventilation path and the storage area of the compressor are partitioned without a sealing structure, and the suction is hardly exerted on the storage area. While ensuring the functions of air circulation, dehumidification and heating, and improving the performance, the common drainage system is used regardless of the storage area and ventilation path with little communication between the compressor storage area and the ventilation path. Can be.
上記に加え、さらに、ユニットケースを2つの分割部材で構成することで部材点数、組立工数、シール構造部が簡略化して製品コスト、ランニングコスト共に低減することができる。   In addition to the above, since the unit case is composed of two divided members, the number of members, the number of assembly steps, and the seal structure can be simplified, and both product cost and running cost can be reduced.
上記に加え、さらに、逆止弁は、ユニットケース内に引圧が働く動作時のみ、その引圧により水溜り部の外壁に設けられ排水口を閉じて気密性よく外気を遮断して空調ユニットの機能を保全しながら、万が一の場合の多量の水溜りには押し開かれて排水し、非動作時は特に閉まる必要はなく、閉じ習性のない簡単なフラップ式の弁片にて低コストに実現できるし、引圧が働く収容域、通風路共に適用できる。   In addition to the above, the check valve is an air-conditioning unit that is provided on the outer wall of the water reservoir by closing the drainage port and shuts off the outside air with good airtightness only during operation in which the pressure is applied inside the unit case. In the event of an emergency, a large amount of water pool is pushed open and drained, and when not in operation, it does not need to be closed. It can be realized, and can be applied to both the housing area and the ventilation path where the attractive pressure works.
本発明の実施の形態に係る空調ユニットにつき、図1〜図15を参照しながら以下に説明し本発明の理解に供する。以下の説明は本発明の具体例であって、特許請求の範囲の内容を限定するものではない。   The air conditioning unit according to the embodiment of the present invention will be described below with reference to FIGS. 1 to 15 for understanding of the present invention. The following description is a specific example of the present invention and does not limit the content of the claims.
本発明の実施の形態に係る空調ユニット39は、図14、図15に示すようにドラム式洗濯乾燥機1に適用した場合の一例であり、これに限られることはない。ドラム式洗濯乾燥機1は、洗濯乾燥機本体44内に図示しないサスペンション構造によって水槽3がフローティング状態に配設され、水槽3内に有底円筒形に形成された回転ドラム2がその軸心方向を正面側から背面側に向けて下向きに傾斜させて配設されている。水槽3の正面側には回転ドラム2の開口端に通じる衣類出入口11が形成され、洗濯乾燥機本体44の正面側に形成された上向き傾斜面に設けられた開口部を開閉可能に閉じる扉9を開くことにより、前記衣類出入口11を通じて回転ドラム2内に対して洗濯物を出し入れすることができる。扉9が上向き傾斜面に設けられているため、洗濯物を出し入れする作業を、腰を屈めることなく実施できる。   The air conditioning unit 39 according to the embodiment of the present invention is an example when applied to the drum type washer / dryer 1 as shown in FIGS. 14 and 15, and is not limited thereto. The drum-type washing / drying machine 1 has a water tank 3 in a floating state in a washing / drying machine main body 44 by a suspension structure (not shown), and a rotating drum 2 formed in a bottomed cylindrical shape in the water tank 3 has an axial direction. Is inclined downward from the front side toward the back side. A clothing doorway 11 leading to the opening end of the rotary drum 2 is formed on the front side of the water tank 3, and a door 9 that closes the opening provided on the upward inclined surface formed on the front side of the washing and drying machine main body 44 so as to be openable and closable. The laundry can be taken in and out of the rotary drum 2 through the clothing entrance 11. Since the door 9 is provided on the upward inclined surface, the work for putting in and out the laundry can be performed without bending the waist.
回転ドラム2には、その周面に水槽3内に通じる多数の透孔8が形成され、内周面の周方向複数位置に攪拌突起(図示せず)が設けられている。この回転ドラム2は水槽3の背面側に取り付けられたモータ7によって正転及び逆転方向に回転駆動される。また、水槽3には、注水管路12及び排水管路13が配管接続され、図示しない注水弁及び排水弁の制御によって水槽3内への注水及び排水がなされる。   The rotating drum 2 is formed with a large number of through holes 8 communicating with the water tank 3 on its peripheral surface, and provided with stirring protrusions (not shown) at a plurality of circumferential positions on the inner peripheral surface. The rotating drum 2 is rotationally driven in the forward and reverse directions by a motor 7 attached to the back side of the water tank 3. Further, a water injection pipe 12 and a drain pipe 13 are connected to the water tank 3, and water is poured into and drained into the water tank 3 by control of a water injection valve and a drain valve (not shown).
扉9を開いて回転ドラム2内に洗濯物及び洗剤を投入してドラム式洗濯乾燥機1の例えば前面上部に設けられた操作パネル66での操作で、その内側などに設けられた制御基板67などによる制御を通じて運転を開始させると、水槽3内には注水管路12から所定量の注水がなされ、モータ7により回転ドラム2が回転駆動されて洗濯工程が開始される。回転ドラム2の回転により、回転ドラム2内に収容された洗濯物は回転ドラム2の内周壁に設けられた攪拌突起によって回転方向に持ち上げられ、持ち上げられた適当な高さ位置から落下する攪拌動作が繰り返されるので、洗濯物には叩き洗いの作用が及んで洗濯がなされる。所要の洗濯時間の後、汚れた洗濯液は排水管路13から排出され、回転ドラム2を高速回転させる脱水動作により洗濯物に含まれた洗濯液を脱水し、その後、水槽3内に注水管路12から注水してすすぎ工程が実施される。このすすぎ工程においても回転ドラム2内に収容された洗濯物は回転ドラム2の回転により攪拌突起により持ち上げられて落下する攪拌動作が繰り返されてすすぎ洗いが実施される。   When the door 9 is opened, laundry and detergent are put into the rotary drum 2 and the operation of the operation panel 66 provided in the upper part of the front surface of the drum-type washing / drying machine 1, for example, the control board 67 provided on the inside thereof is provided. When the operation is started through such control as described above, a predetermined amount of water is injected into the water tank 3 from the water injection pipe 12, and the rotary drum 2 is driven to rotate by the motor 7 to start the washing process. By the rotation of the rotating drum 2, the laundry accommodated in the rotating drum 2 is lifted in the rotating direction by the stirring protrusion provided on the inner peripheral wall of the rotating drum 2, and the stirring operation of dropping from the lifted appropriate height position Is repeated, so that the laundry has the effect of tapping and washing. After the required washing time, the dirty washing liquid is discharged from the drain pipe 13, and the washing liquid contained in the laundry is dehydrated by a dehydrating operation that rotates the rotating drum 2 at a high speed. Rinsing is performed by pouring water from the passage 12. Also in this rinsing step, the laundry stored in the rotary drum 2 is rinsed by repeating the stirring operation in which the laundry is lifted by the stirring protrusion by the rotation of the rotary drum 2 and dropped.
このドラム式洗濯乾燥機1には、回転ドラム2内に収容した洗濯物を乾燥する機能が設けられている。そのためにドラム式洗濯乾燥機1は、既述したように、空調ユニット39と、水槽3内の空気を吸引排気して空調ユニット39に導入し除湿、加熱に供した乾燥した高温空気を再び水槽3内に送風する循環送風経路5を内蔵し、循環送風経路5の空調ユニット39よりも下流に送風ファン15を設けている。   The drum-type washing / drying machine 1 has a function of drying laundry stored in the rotary drum 2. For this purpose, the drum-type washing and drying machine 1, as described above, draws the air in the air conditioning unit 39 and the water tank 3 into the air conditioning unit 39 and introduces it into the air conditioning unit 39 to remove the dried high-temperature air that has been used for dehumidification and heating. A circulation fan passage 5 for blowing air is built in 3, and a blower fan 15 is provided downstream of the air conditioning unit 39 in the circulation fan passage 5.
この送風ファン15を回転駆動すると、循環送風経路5に空気の流れが発生して洗濯物を収容した回転ドラム2内の湿った空気は透孔8を通じて水槽3から送風ファン15側への循環空気導入管路16にて吸引排気される。この排気される湿った空気は、送風ファン15の上流側に直結されるなどして位置する空調ユニット39の通風路393内に吸引導入口391から導入されて、その途中に位置した蒸発器31に空気中の水分を結露させて除湿することと、凝縮器32との熱交換により加熱することとで、常に乾燥した高温の空気とされる。この乾燥した高温の空気は吸引排出口392を通じ送風ファン15に吸引されてから水槽3への送風管路33に送り出されて水槽3内に送風される。水槽3内に送風された高温の乾燥空気は透孔8を通じて回転ドラム2内に入って衣類などの洗濯物に曝されながら水槽3へと抜け、再度循環空気導入管路16へと導入され、以上の循環送風経路5での空気の循環の繰り返しにより乾燥工程が実施される。   When the blower fan 15 is rotationally driven, air flows in the circulation blower path 5 so that the damp air in the rotary drum 2 containing the laundry is circulated from the water tank 3 to the blower fan 15 through the through holes 8. The air is sucked and exhausted through the introduction pipe line 16. The exhausted moist air is introduced from the suction inlet 391 into the ventilation path 393 of the air conditioning unit 39 that is located directly connected to the upstream side of the blower fan 15, and the evaporator 31 located in the middle thereof. By dehumidifying the water in the air by dew condensation and heating by heat exchange with the condenser 32, the air is always dry and hot. The dried high-temperature air is sucked into the blower fan 15 through the suction / discharge port 392 and then sent out to the blower conduit 33 to the water tank 3 to be blown into the water tank 3. The high-temperature dry air blown into the water tank 3 enters the rotary drum 2 through the through holes 8 and escapes to the water tank 3 while being exposed to laundry such as clothes, and is again introduced into the circulating air introduction pipe line 16. The drying process is carried out by repeating the circulation of the air in the circulating air flow path 5 described above.
なお、この循環送風経路5を利用した乾燥工程では、循環送風経路5を循環される空気中に主として衣類などの洗濯物から発生する糸屑などの異物が混じって循環し、蒸発器31や凝縮器32の目詰まり、送風ファン15の回転部への噛み込み、送風ファン15の内面への堆積といった乾燥工程を実施するのに支障を来しやすく、面倒なメンテナンスを頻繁に行う必要があることから、循環送風経路5の途中に、具体的には蒸発器31、凝縮器32、送風ファン15の上流側、従って、前記循環空気導入管路16の途中に、循環空気中の異物を除去するフィルタ35を収容したフィルタ室36を設けることが一般的になっている。これによって、洗濯物を乾燥させた後の空気に異物が混入して蒸発器31側の循環空気導入管路16側に導入されてきても、フィルタ室36を通る際にフィルタ35によって捕集され、下流側への循環空気に混入することはない。従って、蒸発器31、凝縮器32、送風ファン15の機能が長期に保全される。しかし一方では、フィルタ室36内のフィルタ35には捕集された異物が堆積していき、循環空気の通過抵抗が徐々に増していき、乾燥機能を低下させる問題があるので、フィルタ35は一般の場合と同様に着脱できるように設けられる。また、空調ユニット39は送風ファン15との直結によって、それらを単体で取り扱える空調・ファンユニット81を構成しているが、これに限られることはない。   In the drying process using the circulation air passage 5, foreign matter such as lint generated from laundry such as clothes is circulated in the air circulated through the circulation air passage 5, and the evaporator 31 and the condensation are circulated. It is difficult to carry out a drying process such as clogging of the vessel 32, biting into the rotating part of the blower fan 15, and accumulation on the inner surface of the blower fan 15, and frequent troublesome maintenance is required. In the middle of the circulation air flow path 5, specifically, the upstream side of the evaporator 31, the condenser 32, and the blower fan 15, and thus in the middle of the circulation air introduction pipe line 16, foreign matters in the circulation air are removed. It is common to provide a filter chamber 36 that houses the filter 35. Thus, even if foreign matter is mixed into the air after the laundry is dried and introduced into the circulating air introduction pipe 16 side on the evaporator 31 side, it is collected by the filter 35 when passing through the filter chamber 36. , It will not be mixed into the circulating air downstream. Therefore, the functions of the evaporator 31, the condenser 32, and the blower fan 15 are maintained for a long time. However, on the other hand, the collected foreign matter accumulates on the filter 35 in the filter chamber 36, and there is a problem that the passage resistance of the circulating air gradually increases and the drying function is deteriorated. It is provided so as to be detachable as in the case of. In addition, the air conditioning unit 39 constitutes an air conditioning / fan unit 81 that can be handled alone by being directly connected to the blower fan 15, but is not limited thereto.
ここで、結露水が生じる蒸発器31は凝縮器32と共に熱交換部395をなし、そのユニットケース38おける底部の除湿域に対応する範囲に結露水の貯留部63が設けられて、排水ポンプ64を持った排水管路65が接続され、図示しない水位センサによる水位の検出の基に過不足ない排水が行われる。しかし、何らかの排水異常で水位が異常上昇すると貯留している結露水が循環送風経路5の他部分へ及びかねない。これらのことがあって、熱交換部395は循環送風経路5の最低位部に位置するように設けている。   Here, the evaporator 31 in which condensed water is generated constitutes a heat exchanging portion 395 together with the condenser 32, and a condensed water storage portion 63 is provided in a range corresponding to the dehumidified region at the bottom of the unit case 38, and a drain pump 64. A drainage pipe 65 having a water level is connected, and drainage without excess or deficiency is performed based on detection of a water level by a water level sensor (not shown). However, if the water level rises abnormally due to some drainage abnormality, the stored dew condensation water may reach the other part of the circulation air flow path 5. For these reasons, the heat exchanging part 395 is provided so as to be positioned at the lowest part of the circulation air flow path 5.
以上のように種々な機器に搭載して働く空調ユニット39は、搭載する機器の大型化、製品価格、メンテナンスの手間、ランニングコストに影響するため、小型化、部品点数、組立工数の削減、交換部品の削減が望まれる。これらに対応して本実施の形態の空調ユニット39は、特に、図1〜図5に示すように、吸引導入口391および吸引排出口392を持ったユニットケース38内に、吸引導入口391から吸引排出口392への通風路393途中に位置して循環空気を除湿し加熱する蒸発器31および凝縮器32よりなる熱交換部395と、この熱交換部395に冷媒を循環させる圧縮機37と、を内蔵した基本構成において、ユニットケース38は、複数の、具体的には上下2つの分割部材381、382からなり、各分割部材381、382どうしがユニットケース38の外面に臨んでなす割線383間にシール部材384を連続に挟持してユニットケース38の内外をエアタイトし、ユニットケース38の既述した貯留部63で代表される水溜り部の外壁に、溜り水によって開かれて溜まり水を排水させるが外気の吸引を阻止する図2、図3、図7に示すような排水機構101を設けている。   As described above, the air-conditioning unit 39 mounted and operated on various devices affects the size of the mounted devices, product price, maintenance labor, and running costs. Therefore, the air-conditioning unit 39 is reduced in size, the number of parts, the number of assembly steps, and replacement. Reduction of parts is desired. Corresponding to these, the air conditioning unit 39 of the present embodiment has a suction inlet 391 in a unit case 38 having a suction inlet 391 and a suction outlet 392, as shown in FIGS. A heat exchanging unit 395 including an evaporator 31 and a condenser 32 for dehumidifying and heating the circulating air located in the air passage 393 to the suction / exhaust port 392, and a compressor 37 for circulating the refrigerant in the heat exchanging unit 395; , The unit case 38 includes a plurality of, specifically, upper and lower divided members 381 and 382, and a dividing line 383 formed by the divided members 381 and 382 facing the outer surface of the unit case 38. A seal member 384 is continuously sandwiched between the unit case 38 and the inside and outside of the unit case 38 is airtight. The wall, Figure 2 is allowed to drain accumulated water opened by stagnant water to prevent outside air suction, Figure 3, is provided with a water discharge mechanism 101 as shown in FIG.
このように、ユニットケース38は複数の分割部材381、382で構成されるが、それら各分割部材381、382がユニットケース38の外面に臨んでなす割線383間にシール材384を挟持してユニットケース38の内外をエアタイトする簡単なシール構造で、吸引導入口391から吸引排出口392への通風路393に例え圧縮機37の収容域394側との連通があっても吸引作用が積極的に及ばず空気溜まりになる収容域394の影響なく、吸引空気の循環と除湿および加熱との機能を確保することができる。また、通風路393および収容域394相互の連通を利用して収容域394、通風路393の別なく、万が一の場合の急な水溜まりには、ユニットケース38の貯留部63などに設けた排水機構101が、溜り水によって開かれて溜まり水を排水させることで対応しながら、外気の吸引は阻止して循環空気を導入して熱交換し排出する機能を確保するようにできる。   As described above, the unit case 38 is composed of a plurality of divided members 381 and 382, and the unit member 38 is sandwiched between the dividing lines 383 formed by the divided members 381 and 382 facing the outer surface of the unit case 38. With a simple seal structure that airtights the inside and outside of the case 38, the suction action is positive even if the ventilation path 393 from the suction inlet 391 to the suction outlet 392 communicates with the housing area 394 side of the compressor 37, for example. The functions of circulation, dehumidification, and heating of the suction air can be ensured without being affected by the accommodation area 394 that becomes an air reservoir. In addition, the drainage mechanism provided in the storage portion 63 of the unit case 38 or the like for a sudden water pool in the unlikely event of the storage area 394 and the ventilation path 393 using the communication between the ventilation path 393 and the storage area 394. While 101 responds by being opened by the accumulated water and draining the accumulated water, it is possible to prevent the outside air from being sucked and to secure the function of introducing the circulating air and exchanging and discharging the heat.
この結果、ユニットケース38を構成する複数の分割部材381、382がユニットケース38の外面に臨んでなす割線383間でシールしてユニット内外をエアタイトした簡単なシール構造で、通風路393の圧縮機37の収容域394側との連通の影響なく吸引空気の循環と除湿および加熱との機能を確保しながら、互いの連通を利用して収容域394、通風路393の別なく、貯留部63を中心とした熱交換部395での凝縮結露水を主体とする通常排水系はもとより、万が一の場合の急な水溜まりには、ユニットケース38の貯留部63で代表する水溜り部に設けた排水機構101によって、循環空気を導入して熱交換し排出する機能を確保しながら対応でき、シール箇所が従来よりも少ない分だけ、部品点数、組立工数、および部品交換数が低減するので、製品コストおよびランニングコストが共に低減する。   As a result, the compressor of the ventilation path 393 has a simple sealing structure in which a plurality of dividing members 381 and 382 constituting the unit case 38 are sealed between the dividing lines 383 formed facing the outer surface of the unit case 38 and the inside and outside of the unit are airtight. 37, while maintaining the functions of suction air circulation, dehumidification, and heating without the influence of communication with the storage area 394 side of the storage area 394, the storage section 63 can be configured without using the communication area 394 and the ventilation path 393. The drainage mechanism provided in the water reservoir represented by the storage portion 63 of the unit case 38 is not limited to the normal drainage system mainly composed of condensed condensed water in the heat exchanging portion 395, but in the event of a sudden water pool. 101, it is possible to cope with ensuring the function of introducing circulating air and exchanging and discharging heat. Since the number of replacement is reduced, the product cost and running cost are both reduced.
特に、本実施の形態のようにユニットケース38は、2つの分割部材381、382で構成していると、部材点数、組立工数、シール構造部がさらに低減する。   In particular, when the unit case 38 is configured by two divided members 381 and 382 as in the present embodiment, the number of members, the number of assembly steps, and the seal structure portion are further reduced.
また、本実施の形態でも、収容域394と通風路393とは区画部386にて区画しているが、シール構造は省略している。このようにシール構造がないことにより、通風路393に例え収容域394側との連通が双方の区画部にあっても、この区画効果が合わさって収容域394に吸引作用がほとんど及ばなくして、吸引空気の循環と除湿および加熱との機能をより確実に確保し、性能を高められる。区画部386は上下各分割部材381、382の双方に一体形成した上下区画壁386a、386bの突き合わせ構造にて行い、ユニットケース38が収容域394、通風路393を区画して持った複雑な空間形状体であるのを、2部材の簡単な構成で実現している。しかも、上下区画壁386a、386bに代えて、上下分割部材381、382の一方に一体成形した単体の区画壁として区画部386とすることもできる。   Also in the present embodiment, the housing area 394 and the ventilation path 393 are partitioned by the partitioning portion 386, but the seal structure is omitted. Because there is no seal structure in this way, even if the ventilation path 393 communicates with the accommodation area 394 side in both of the compartments, this compartment effect is combined and the accommodation area 394 has almost no suction action, The function of the suction air circulation, dehumidification and heating can be ensured more reliably and the performance can be improved. The partition portion 386 is formed by a butting structure of upper and lower partition walls 386a and 386b integrally formed on both the upper and lower divided members 381 and 382, and the unit case 38 has a complicated space having a housing area 394 and a ventilation path 393. The shape body is realized with a simple configuration of two members. Moreover, instead of the upper and lower partition walls 386a and 386b, the partition portion 386 can be formed as a single partition wall integrally formed with one of the upper and lower split members 381 and 382.
前記弁機構101は図2、図3、図7に示すように、貯留部63などの水溜まり部の外壁に設けられた排水口101aと、この排水口101aをユニットケース38内の引圧によって外側から閉じる逆止弁101bとしてあり、逆止弁101bは、ユニットケース38内に引圧が働く動作時のみ、その引圧により貯留部63など水溜り部の外壁に設けられ排水口101aを閉じて気密性よく外気を遮断して空調ユニット39の機能を保全しながら、万が一の場合の多量の水溜りにはその水の自重によって押し開かれて排水させられるし、非動作時は特に閉まる必要はなく、閉じ習性のない簡単なフラップ式の弁片にて実現できる。具体的にはゴム片による逆止弁101bとして、その上端に一体成形したフック部101cを排水口101aの上部に設けた取り付け穴101dに弾性係合させるなどして簡単に装着できるし、吸引、吸引解除に対応した閉じ、閉じ解除が頻繁でもその動作ストロークは微小で疲労を促進するようなことはなくメンテナンスの交換部品となることは極めて希である。   As shown in FIGS. 2, 3, and 7, the valve mechanism 101 has a drain port 101 a provided on the outer wall of a water reservoir such as the reservoir 63, and the drain port 101 a is pulled outside by pulling in the unit case 38. The check valve 101b closes the drain port 101a provided on the outer wall of the water reservoir portion such as the storage portion 63 by the pulling pressure only when the pulling pressure works in the unit case 38. While maintaining the function of the air conditioning unit 39 by shutting out the outside air with good airtightness, a large pool of water in the event of an emergency should be pushed open and drained by its own weight, and should be closed when not in operation. It can be realized with a simple flap-type valve piece without closing behavior. Specifically, as a check valve 101b made of a rubber piece, a hook portion 101c integrally formed at the upper end thereof can be easily mounted by elastically engaging with a mounting hole 101d provided in the upper portion of the drain port 101a, and suction, Even when closing and releasing corresponding to suction release are frequent, the operation stroke is very small and does not promote fatigue, and it is extremely rare to become a replacement part for maintenance.
本実施の形態では、通風路393、収容域394の連通構造に関連して急な水溜まりが収容域394の側にも及ぶことがあるかも知れないことに関連して、熱交換部395に対応した貯留部63同様に、収容域394の底部を水溜り部396として弁機構101を設けている。これにより、通風路393、収容域394の高低関係などから一旦収容域394側に及んだ水溜まりが通風路393側の貯留部63側で解消されない場合でも、収容域394の側にて排水できるようになる。   In the present embodiment, in association with the communication structure of the ventilation path 393 and the accommodation area 394, a sudden water pool may reach the side of the accommodation area 394. Similar to the reservoir 63, the valve mechanism 101 is provided with the bottom of the accommodation area 394 as the water reservoir 396. As a result, even if the water pool once reaching the storage area 394 due to the height relationship between the ventilation path 393 and the storage area 394 is not eliminated on the storage section 63 side on the ventilation path 393 side, the water can be drained on the storage area 394 side. It becomes like this.
さらに、ユニットケース38は図1、図4、図5、図11、図12に示すように、長手方向の一端の天井壁の後部に吸引導入口391が、他端の端部壁に吸引排出口392が設けられたほぼ長方体形状をなしている。圧縮機37は図5に示すようにユニットケース38内一端側の前部寄りの収容域394に収容されて、この収容域394と、この収容域394に対しユニットケース38内の後部側および他端部側に広がる通風路393とユニットケース38をなす分割部材381、382の双方から延びて区画部386をなす上下区画壁386a、386bまたは一方から延びる区画壁によって区画されたものとなっている。また、蒸発器31、凝縮器32は、ユニットケース38の長手方向に対向し合う区画部386と端部壁との間の熱交換域393aを前後の吸引導入側と、吸引排出側とに仕切って設けられている。さらに、吸引導入口391は、ユニットケース38の熱交換域393aの天井壁よりも高く上向きに開口し、かつ図2、図5に示すように平面視して収容域394の後部側上にオーバーラップする位置から前記通風路393における熱交換域393aから、ユニットケース38一端側に収容域394の後部へ拡張した一端側後部域393b上に及ぶ大きさで、ユニットケース38外方へのかさ張りなく設けられている。   Further, as shown in FIGS. 1, 4, 5, 11, and 12, the unit case 38 has a suction inlet 391 at the rear of the ceiling wall at one end in the longitudinal direction and a suction exhaust at the end wall at the other end. It has a substantially rectangular parallelepiped shape provided with an outlet 392. As shown in FIG. 5, the compressor 37 is housed in a housing area 394 near the front of one end in the unit case 38, and the housing area 394, the rear side in the unit case 38, and other parts The upper and lower partition walls 386a and 386b extending from both the ventilation path 393 extending to the end side and the dividing members 381 and 382 forming the unit case 38 and the partition wall extending from one side are partitioned. . In addition, the evaporator 31 and the condenser 32 partition the heat exchange area 393a between the partition wall 386 and the end wall facing each other in the longitudinal direction of the unit case 38 into the front and rear suction introduction sides and the suction discharge side. Is provided. Further, the suction inlet 391 opens upward higher than the ceiling wall of the heat exchange area 393a of the unit case 38, and overhangs on the rear side of the accommodation area 394 in plan view as shown in FIGS. From the wrapping position to the size of the heat exchange area 393a in the ventilation path 393 and the one end side rear area 393b extended to the rear part of the housing area 394 on the one end side of the unit case 38, without being bulky outward of the unit case 38 Is provided.
通風路393は、さらに、吸引導入口391の基部開口から一端側後部域393bに滑らかに繋がって循環空気を下向きに案内する縦向き湾曲域393cと、熱交換域393aの後部吸引導入側を、吸引導入口391の高さ未満でこの吸引導入口391からユニットケース38の他端側にかけて上方に拡張した後部上向き拡張域393dと、を備えたものとしている。   The ventilation path 393 further includes a longitudinally curved region 393c that smoothly connects from the base opening of the suction inlet 391 to the rear region 393b on one end side to guide the circulating air downward, and a rear suction introduction side of the heat exchange region 393a. A rear upward expansion region 393d extending upward from the suction introduction port 391 to the other end side of the unit case 38 at a height lower than the suction introduction port 391 is provided.
これにより、ユニットケース38の長手方向一端の天井壁の後部に設けた吸引導入口391と、他端の端部壁に設けた吸引排出口392との間の、ユニットケース38の一端の前部寄りで圧縮機37を収容して区画部386で区画された収容域394を除く、ユニットケース38の長手方向ほぼ一杯に利用した通風路393にて循環空気を吸引導入口391から無理なく吸引、導入して、スムーズに熱交換部395での熱交換に供して、吸引排出口392へ吸引排出されるようにすることができる。このとき、通風路393は、吸引導入口391から導入した循環空気を図5に矢印で示すように、収容域394横の熱交換域393aからユニットケース38の一端側に外れた一端側後部域393bと、熱交換域393aの後部から上部に外れた後部上向き拡張部393dとに受け入れて、熱交換域393aの後部となる吸引導入側で合流させながら、熱交換域393aに設置された熱交換部395の蒸発器31、凝縮器32による均等な通過抵抗による充満効果も手伝って、それら蒸発器31、凝縮器32のほぼ全域を後部から前部へ偏りなくほぼ均等に通過される熱交換流を生成することができる。従って、熱交換効率が向上し空調機能を高められる。   As a result, the front part of one end of the unit case 38 between the suction inlet 391 provided in the rear part of the ceiling wall at one end in the longitudinal direction of the unit case 38 and the suction outlet 392 provided in the end part wall at the other end. The compressor 37 is accommodated at the side, and the circulating air is sucked from the suction inlet 391 without difficulty in the ventilation path 393 that is used almost fully in the longitudinal direction of the unit case 38 except for the housing area 394 partitioned by the partitioning section 386. It can be introduced and smoothly subjected to heat exchange in the heat exchanging unit 395 so as to be sucked and discharged to the suction / discharge port 392. At this time, the ventilation path 393 is configured so that the circulating air introduced from the suction inlet 391 is located at one end side rear area that is removed from the heat exchanging area 393a next to the accommodation area 394 to the one end side of the unit case 38 as indicated by an arrow in FIG. Heat exchange installed in the heat exchange area 393a while being received by the suction introduction side, which is the rear part of the heat exchange area 393a, while being received by the heat transfer area 393a and the rear upward expansion part 393d that is deviated upward from the rear part of the heat exchange area 393a The heat exchange flow that passes almost evenly from the rear part to the front part of the evaporator 31 and the condenser 32 through the entire region of the evaporator 31 and the condenser 32 with the help of the filling effect by the uniform passage resistance by the evaporator 31 and the condenser 32 of the part 395. Can be generated. Therefore, the heat exchange efficiency is improved and the air conditioning function can be enhanced.
この場合、通風路393は、特に、吸引導入口391が平面視して圧縮機37の収容域394の後部側上にオーバーラップする位置から通風路393における一端側後部域393b上にほぼオーバーラップする大きさであることにより循環空気の導入風量を高めながら、吸引導入口391よりも前後幅の小さな一端側後部域393bへの流れは絞られるものの、縦向き湾曲路393cによる案内で乱れや圧損なくスムーズに導入させて熱交換域393aの後部吸引導入側に向かわせられるのに併せ、前記絞りを受ける分だけ、導入空気が吸引導入口391からユニットケース38他端側に延びる後部上向き拡張域393d側に流れ込みやすくすることができる。この結果、通風路393に導入した循環空気の熱交換部395の後向き吸い込み面395aへの均等な広がりをより促進して、熱交換効率をさらに高められる。また、前記縦向き湾曲路393cでは図2に示すように吸引導入空気は流れを曲げられることにより、随伴している洗濯物から除去した水分や混入していることのある洗剤成分や柔軟剤成分を遠心分離することができるし、圧縮機37の上端との干渉を避ける仮想線で示す逃げ形状部393c1では衝突分離作用も受ける。   In this case, in particular, the ventilation path 393 substantially overlaps the one end side rear area 393b of the ventilation path 393 from the position where the suction inlet 391 overlaps the rear side of the accommodation area 394 of the compressor 37 in plan view. Although the flow to the one end side rear region 393b having a smaller front-rear width than the suction introduction port 391 is reduced while increasing the introduction air volume of the circulating air due to the size, the turbulence and pressure loss are guided by the longitudinal curved path 393c. In addition to being introduced smoothly and directed toward the rear suction introduction side of the heat exchange area 393a, the rear upward expansion area where the introduction air extends from the suction introduction port 391 to the other end of the unit case 38 by the amount of the restriction. It can be made easier to flow into the 393d side. As a result, the uniform expansion of the circulating air introduced into the ventilation path 393 to the backward suction surface 395a of the heat exchange section 395 can be further promoted, and the heat exchange efficiency can be further enhanced. Further, as shown in FIG. 2, in the longitudinally curved path 393c, the flow of the suction-introducing air is bent, so that moisture removed from the accompanying laundry, detergent components and softener components that may have been mixed in Can be centrifuged, and the relief shape portion 393c1 shown by the phantom line that avoids interference with the upper end of the compressor 37 also receives a collision separation action.
ここで、既述の貯留部63は、図2、図3、図4、図5に示すように、熱交換域393aにおける熱交換部395の平面視矩形な形状にほぼ一致して熱交換部395を受載する上向きに開放した皿型の熱交換部受載皿393a1をなして形成されている。この熱交換部受載皿393a1上に設置し受載される熱交換部395は、蒸発器31、凝縮器32を相互のフィン395cが微小な熱的切り離し隙間(図示せず)を有して相互が一体となったユニットをなし、前記熱的切り離し隙間によって、凝縮器32側から蒸発器31側への熱移動を、蒸発器31での霜や氷の成長を抑え、低外気温でも冷媒の温度上昇と共に霜を溶かして高い乾燥効率を確保できる程度に抑えられるようにしている。これにより、従来、蒸発器31、凝縮器32間に設けていた隔離空間を省略して設置スペースを小さくしながら、吸引排出口392側への隔離空間での遊びが原因したバイパス通過を抑えて有効面積を大きく保ち熱交換効率、乾燥効率を高め、乾燥騒音の低減も図れるようになる。   Here, as shown in FIGS. 2, 3, 4, and 5, the above-described storage unit 63 substantially coincides with the rectangular shape in plan view of the heat exchange unit 395 in the heat exchange region 393 a and is a heat exchange unit. It is formed as a dish-shaped heat exchange section receiving tray 393a1 that opens upward to receive 395. The heat exchanging unit 395 installed and received on the heat exchanging unit receiving tray 393a1 has a minute thermal separation gap (not shown) between the evaporator 31 and the condenser 32 by the fins 395c. The unit is formed as an integral unit, and heat transfer from the condenser 32 side to the evaporator 31 side is suppressed by the thermal separation gap, so that the growth of frost and ice in the evaporator 31 is suppressed. As the temperature rises, frost is melted so that high drying efficiency can be secured. This eliminates the isolation space previously provided between the evaporator 31 and the condenser 32 and reduces the installation space, while suppressing bypass passage caused by play in the isolation space toward the suction / discharge port 392 side. The effective area can be kept large, heat exchange efficiency and drying efficiency can be increased, and drying noise can be reduced.
しかも、熱交換部395は、その後ろ向きとなっている吸い込み面395aと、これに対向するユニットケース38の熱交換域393aの吸引導入側後部壁との対向距離が、吸引導入口391に繋がる一端側後部域393b側からユニットケース38の他端部側に向け小さくなるように、ユニットケース38の長手方向に対して図4、図5に示すような斜めになる向きで配置してある。これにより、熱交換域393aをその一端側後部域393b側から吸引排気口392に向け最短となる斜めに向むく図4に示す方向Aに対し、熱交換部395のフィン395cの向きの傾き角θが、熱交換部395をユニットケース38の長手方向に配置する場合に比し小さくなるので、この小さくなった分だけ通風抵抗がさらに低減し、かつ熱交換部395を通過する通風分布がより均一化するので、除湿効率、加熱効率共にさらに向上し、乾燥効率を高められるし、より静音となる。   Moreover, the heat exchanging portion 395 has one end where the facing distance between the suction surface 395a facing backward and the suction introduction side rear wall of the heat exchange area 393a of the unit case 38 facing the suction surface 395a is connected to the suction introduction port 391. 4 and FIG. 5 are arranged in an oblique direction with respect to the longitudinal direction of the unit case 38 so as to decrease from the side rear region 393b side toward the other end side of the unit case 38. Thereby, the inclination angle of the direction of the fins 395c of the heat exchanging portion 395 with respect to the direction A shown in FIG. 4 in which the heat exchanging region 393a is inclined from the one end side rear region 393b side to the suction exhaust port 392 is the shortest. Since θ is smaller than when the heat exchanging portion 395 is arranged in the longitudinal direction of the unit case 38, the airflow resistance is further reduced by the smaller amount and the airflow distribution passing through the heat exchanging portion 395 is further increased. Since it is made uniform, both the dehumidification efficiency and the heating efficiency are further improved, the drying efficiency can be increased, and the noise is further reduced.
ここに、熱交換部395の設置向きは、熱交換域393aをその一端側後部域393bから吸引排気口392に向け最短に向かう斜めの方向Aに可能な限り一致させるのが最良となる。   Here, the installation direction of the heat exchanging portion 395 is best matched with the heat exchanging region 393a as much as possible in the oblique direction A that is the shortest from the rear end region 393b toward the suction exhaust port 392.
さらに、熱交換域393aは、図6に示すように熱交換部受載皿393a1およびこれに設置する熱交換部395の吸引排出側が貯留部63として低く、熱交換部395の吸引空気導入側が高くなるユニットケース38の底部形状を有して形成され、収容域394は図2に示すように貯留部63よりもさらに低くなるようにユニットケース38の底部形状を有して形成されている。これにより、ユニットケース38での圧縮機37の設置高さを抑えられるし、重心を下げられる。   Further, as shown in FIG. 6, the heat exchanging area 393a is low on the suction discharge side of the heat exchanging part receiving tray 393a1 and the heat exchanging part 395 installed therein as the storage part 63, and on the suction air introduction side of the heat exchanging part 395 is high. As shown in FIG. 2, the storage area 394 is formed with the bottom shape of the unit case 38 so as to be lower than the storage portion 63. Thereby, the installation height of the compressor 37 in the unit case 38 can be suppressed, and the center of gravity can be lowered.
熱交換部受載皿393a1は、熱交換部395を図1に示すようにフィルタを介在させずに直置きして受載し、蒸発器31を受ける部分を蒸発器31で生じる結露水を受け入れて排水する結露水排水皿21とし、熱交換部395の凝縮器32を受ける部分を、蒸発器32を受ける部分から区画して、循環空気に随伴している洗濯物から除去した水分や循環系に入り込むことのある洗剤や柔軟剤の成分を、熱交換部395を通過する前に分離して受け入れ排水する分離水排水皿23とし、相互を仕切る仕切り壁28により一応仕切っている。しかし、排水口22は結露水排水皿21に設け、分離水排水皿23は結露水排水皿21を通じ排出するようにしている。   The heat exchanging part receiving tray 393a1 receives the heat exchanging part 395 by directly placing it without interposing a filter as shown in FIG. The portion of the heat exchanger 395 that receives the condenser 32 is partitioned from the portion that receives the evaporator 32, and the moisture and circulation system removed from the laundry accompanying the circulating air. The components of the detergent and softener that may get into the separation water drain tray 23 for separating and receiving and draining before passing through the heat exchanging section 395 are partitioned by a partition wall 28 that partitions each other. However, the drain port 22 is provided in the condensed water drain tray 21, and the separated water drain tray 23 is discharged through the condensed water drain tray 21.
これは、循環空気中の水は蒸発器31を通ることで結露水として除去し結露水排水皿21から排出して問題はないが、循環空気中に入り込むことのある粘度の高い洗剤や柔軟剤の成分は熱交換部395や送風ファン15に入り込むと、付着して空気通路を狭めたり、詰まらせたり、送風ファン15の回転抵抗を高めたりするので、これを熱交換部395に入り込む前に気液分離し、分離水排水皿23から結露水排水皿21を通じ排水ポンプ64に負担を掛けることなく排水することを目的としている。この気液分離には当然のことながら循環空気に随伴している水も含まれ、気液分離した粘性の高い洗剤や柔軟剤の成分を同時に気液分離した水で洗い流し、また希釈して排水ポンプ64に負担を掛けないようにでき好都合である。   This is because the water in the circulating air is removed as condensed water by passing through the evaporator 31 and discharged from the condensed water drain tray 21, but there is no problem, but a detergent or softener with high viscosity that may enter the circulating air. When the component enters the heat exchanging part 395 or the blower fan 15, it adheres and narrows or clogs the air passage, or increases the rotational resistance of the blower fan 15. The purpose is to perform gas-liquid separation and drain water from the separated water drain tray 23 through the condensed water drain tray 21 without imposing a burden on the drain pump 64. Naturally, this gas-liquid separation also includes the water accompanying the circulating air, and the components of the highly viscous detergent and softener separated by gas-liquid are washed away with water that has been gas-liquid separated at the same time, diluted and drained. The pump 64 is advantageously not burdened.
この気液分離のために、熱交換域393aの吸引空気導入側は、ユニットケース38の下分割部材382において、一端側後部域393bを含む吸引導入口391および後部上向き拡張部393dから、熱交換部395の後ろ向き吸い込み面395aとユニットケース38の後部壁との間を下向きに流れる空気を、熱交換部395の図2、図3、図5に示すような高さ方向途中位置で一旦受け止めて熱交換部395の側に案内するように、ユニットケース38の後部壁から前部側にほぼ水平に延びた棚部24と、この棚部24から熱交換部受載皿393a1まで斜め下方に傾斜して繋がり、棚部24を経た吸引導入空気を熱交換部受載皿393a1上に設置され受載される熱交換部395の後ろ向き吸い込み面395a全面を通過するよう案内する傾斜部25を形成している。   For this gas-liquid separation, the suction air introduction side of the heat exchange area 393a exchanges heat with the lower split member 382 of the unit case 38 from the suction inlet 391 including the rear end area 393b on one end side and the rear upward extension 393d. The air flowing downward between the rearward suction surface 395a of the unit 395 and the rear wall of the unit case 38 is temporarily received at the midway position in the height direction as shown in FIGS. 2, 3, and 5 of the heat exchange unit 395. A shelf 24 extending substantially horizontally from the rear wall of the unit case 38 to the front side so as to be guided to the heat exchange unit 395 side, and inclined obliquely downward from the shelf 24 to the heat exchange unit receiving tray 393a1 Thus, the suction-introduced air that has passed through the shelf 24 passes through the entire rear-facing suction surface 395a of the heat exchanging unit 395 that is installed on the heat exchanging unit receiving tray 393a1. Forming an inclined portion 25 that.
これにより、通風路393に導入される吸引空気は吸引導入口391および後部上向き拡張部393dから熱交換部395に向け下向きに流れる途中で棚部24に衝突して熱交換部395の側に案内されるが、この衝突によって吸引空気に随伴している洗濯物から除去した水分、循環系に入り込むことのある洗剤や柔軟剤の成分を吸引空気から衝突分離させられる。分離された分離水、洗剤や柔軟剤の成分は吸引空気の流れもあって棚部24を傾斜部25の側に移動し、傾斜部25を伝い落ちる。具体的には、分離水が積極的に傾斜部25の側に押し流されながら、粘性の高い洗剤や柔軟剤の成分を洗い流す形で傾斜部25側に至って後、吸引空気の流れに加え、重力の作用が加わって傾斜部25を伝い落ちる。傾斜部25を伝い落ちる分離水などは傾斜部25の下部で図3、図7に示すリブ26により堰止めた上で、一端側、図示例では収容域394側が前記分離水排水皿23に通じる図1、図7に示す連通路27へと逃がし、分離水排水皿23に流れ込むようにしている。   As a result, the suction air introduced into the ventilation path 393 collides with the shelf 24 while flowing downward from the suction introduction port 391 and the rear upward expansion portion 393d toward the heat exchange portion 395 and is guided to the heat exchange portion 395 side. However, the moisture removed from the laundry accompanying the suction air and the components of the detergent and softening agent that may enter the circulation system by the collision can be separated from the suction air. The components of the separated water, detergent and softening agent that have been separated move the shelf 24 toward the inclined portion 25 due to the flow of suction air, and flow down the inclined portion 25. Specifically, while the separated water is actively washed away to the inclined portion 25 side, the components of the highly viscous detergent and softener are washed away to reach the inclined portion 25 side, and then the gravity air is added to the flow of the suction air. As a result of the action of the above, it moves down the inclined portion 25. Separation water or the like flowing down the inclined portion 25 is blocked by the rib 26 shown in FIGS. 3 and 7 at the lower portion of the inclined portion 25, and one end side, in the illustrated example, the accommodation area 394 side leads to the separated water drainage tray 23. It escapes to the communication path 27 shown in FIGS. 1 and 7 and flows into the separated water drain tray 23.
一方、熱交換部受載皿393a1および吸引排出側でなす貯留部63全体の底部が、結露水排水皿21に設けた排水口22に向かって低くなるようにしてある。これに併せ、分離水排水皿23は、吸引排気側との仕切り壁29に微小な連通部29aを持ち、結露水排水皿21との仕切り壁28に微小な連通部28aを持っている。これによって、分離水排水皿23に流れ込んだ分離水などは連通部28aを通じ結露水排水皿21に流れ込んだ後、結露水排水皿21にある排水口22へと流れる。また、排水口22に接続された排水ポンプ64の動作不良などで吸引排出側に万が一オーバーフローし、あるいは溜まることがある水は、連通部29aを通じて分離水排水皿23に流入した後、連通部28aを通じ結露水排水皿22へと流れ、排水口22に至る。   On the other hand, the bottoms of the heat exchanger receiving tray 393a1 and the entire storage portion 63 formed on the suction / discharge side are lowered toward the drain port 22 provided in the condensed water drain tray 21. In addition to this, the separated water drainage tray 23 has a minute communication portion 29 a on the partition wall 29 with the suction exhaust side, and has a minute communication portion 28 a on the partition wall 28 with the condensed water drainage tray 21. As a result, the separated water or the like that has flowed into the separated water drain tray 23 flows into the condensed water drain tray 21 through the communication portion 28 a, and then flows into the drain port 22 in the condensed water drain tray 21. In addition, water that may overflow or accumulate on the suction / discharge side due to malfunction of the drain pump 64 connected to the drain port 22 flows into the separated water drain tray 23 through the communication portion 29a, and then communicates with the communication portion 28a. Flows to the dew condensation water drain tray 22 and reaches the drain outlet 22.
連通部28a、29aは前記フィルタを設けないで熱交換部395を熱交換部受載皿393a1上に設置したことに対応して、水はスムーズに通るが、糸屑や循環空気中に混入していることのある粘度の高い洗剤や柔軟剤の成分はそのまま通さない大きさに設定してある。同様に、結露水排水皿22および分離水排水皿23の流路途中にも、糸屑、洗剤や柔軟剤の成分を通さない連通部41、および邪魔突起42を設けてある。この連通部28a、29a、41、邪魔突起42で糸屑を受け止めてもその総量は少なく、正常な排水に影響することはない。逆に受け止めた糸屑は洗剤成分の受け止めに役立つ。洗剤成分の受け止めは水の通りを邪魔するが邪魔された水は溜まりながら洗剤を希釈し、やがては薄まった洗剤を排水口22へと流し去ることになる。ここに、循環空気に入り込むことのある洗剤や柔軟剤の成分は、循環空気に随伴している洗濯物から除去した水分と共に、熱交換部395を通過する前に効果的に分離され、しかも、希釈された後排水されるので排水ポンプ64に負担を掛けたり、停止させてしまうようなことはない。しかも、連通部41は、流路を横断する隔壁41aの中間部をV型に切除して形成しており、底部に沿って押し流される糸屑、洗剤や柔軟剤の成分の通りを確実に制限するが、通りを制限された糸屑が少しかさ高になって水の通りを制限することがあっても、通りを制限される水は糸屑よりもかさを増すのと、連通部41が上に向け広がり制限度を低減していることとで、薄まった洗剤などの成分と共に容易に先へ流れることができるので、別段問題にはならない。   Corresponding to the fact that the heat exchanging portion 395 is installed on the heat exchanging portion receiving tray 393a1 without providing the filter, the communicating portions 28a and 29a pass smoothly, but are mixed into yarn waste and circulating air. The components of detergents and softeners with high viscosity that may have passed are set so as not to pass through. Similarly, in the middle of the flow path of the condensed water drainage tray 22 and the separated water drainage tray 23, a communicating portion 41 and baffle protrusions 42 that do not allow components of yarn waste, detergent or softener to pass through are provided. Even if the thread waste is received by the communication portions 28a, 29a, 41 and the baffle protrusions 42, the total amount thereof is small, and normal drainage is not affected. On the contrary, the yarn waste that is received serves to receive the detergent components. Receiving the detergent component obstructs the passage of water, but the disturbed water accumulates and dilutes the detergent. Eventually, the diluted detergent is washed away to the drain port 22. Here, the components of the detergent and softening agent that may favor the circulating air are effectively separated before passing through the heat exchanging portion 395, together with the moisture removed from the laundry accompanying the circulating air, Since the water is drained after being diluted, the drain pump 64 is not burdened or stopped. Moreover, the communication part 41 is formed by cutting the middle part of the partition wall 41a crossing the flow path into a V shape, and reliably restricts the passage of the components of the thread waste, the detergent and the softening agent that are swept along the bottom part. However, even if the yarn waste restricted in the street is slightly bulky and restricts the passage of water, the communication portion 41 is said that the water restricted in the street becomes bulkier than the yarn waste. Since the degree of restriction of spreading upward is reduced, it can easily flow forward together with components such as a diluted detergent, so that it is not a problem.
さらに、上記棚部24、傾斜部25は、ユニットケース38の下半の後部域の内部スペースを狭めることで有効に作用するが、結果として、ユニットケース38の下半の後部壁に内側への図2、図5に示す凹み形状を付与して、棚部24の下に後方および下方に開放した空きスペースSを形成している。この空きスペースSは、空調ユニット39や空調・ファンユニット81が図1に示すように洗濯機本体44の底部上に後部壁に沿って設置されたとき、図2、図14に示すように空調ユニット39や空調・ファンユニット81の外回りで行う配線の結線スペース、センサなど外部機器の設置スペースなどとして有効利用できる。   Further, the shelf 24 and the inclined portion 25 work effectively by narrowing the internal space in the lower half of the lower half of the unit case 38. As a result, the rear wall of the lower half of the unit case 38 is inwardly connected. 2 and FIG. 5 is provided, and the empty space S opened rearward and downward is formed below the shelf 24. When the air conditioning unit 39 and the air conditioning / fan unit 81 are installed along the rear wall on the bottom of the washing machine main body 44 as shown in FIG. 1, the empty space S is air-conditioned as shown in FIGS. It can be used effectively as a wiring connection space around the outside of the unit 39 or the air conditioning / fan unit 81, a space for installing external devices such as sensors.
なお、棚部24および傾斜部25は、下部分割部材382の側で一体形成してその連続性を確保しやすくしてあり、棚部24は、下部分割部材382の上部分割部材381との間で割線383をなして接合する接合フランジ382aより少し下の位置に形成してある。接合フランジ382aはその全周の凹条内に環状のシール部材384を収容し、上部分割部材381の接合フランジ381aの凸条が前記凹条に嵌り込む凹凸嵌合にてシール部材384を挟み付ける接合構造にて割線383間をシールしている。この接合およびシールは接合フランジ381a、382aどうしを図7に示すように周方向に多数設けられた締結穴を利用した図3に示すようなネジ締結部68によって確固に保持する。   The shelf 24 and the inclined portion 25 are integrally formed on the lower divided member 382 side so as to ensure the continuity, and the shelf 24 is located between the lower divided member 382 and the upper divided member 381. And formed at a position slightly below the joining flange 382a to be joined by forming a dividing line 383. The joining flange 382a accommodates an annular seal member 384 in a recess on the entire circumference thereof, and the seal member 384 is sandwiched by an uneven fitting in which the projection of the joining flange 381a of the upper split member 381 fits into the recess. The gap between the dividing lines 383 is sealed with a joining structure. The joining and sealing are firmly held by joining screws 381a and 382a by screw fastening portions 68 as shown in FIG. 3 using a number of fastening holes provided in the circumferential direction as shown in FIG.
ここで、熱交換部395は、収容域394側で通風路393と収容域394との区画部386が上下分割部材381、382間に形成する開口51に図1、図2に示すように上下に挟み嵌り込まれる端部に、図2、図4、図5に示すような前後に張り出した金属板、例えばアルミ系などの耐食性の高い仕切り壁52を持ち、この仕切り壁52が開口51の口縁、特に縦向きの口縁に形成したガイド溝51aに上方から挿入されることで、収容域394側端部側を位置決めされ、かつ、通風路393と収容域394との開口51部分での通気を抑えるラフなシール構造をなしている。また、熱交換部395の反対側の端部、つまり吸引排出口392側の端部は図4、図6に示すような下分割部材382の熱交換部受載皿393a1の吸引排気口392側の端部の前後のコーナ部に上向きに一体形成したガイド53a、53b間に上方からラフに嵌め入れて位置決めしている。これら両端部の位置決めによって熱交換部395は熱交換部受載皿393a1上の所定位置に位置決めされる。熱交換部395はまた、上分割部材381の天井壁裏面に区画壁386aからこれに対向する他端部壁間に亘って下向きに形成した図8に示すようなリブ状の仕切り壁54が当接していることにより、区画部386の開口51の上部口縁と協働して、熱交換部395が熱交換部受載皿393a1から浮くのを防止している。同時に、熱交換域393aにおいて吸引導入側の吸引導入空気が熱交換部395まわりから吸引排出側にバイパスするのを防止している。   Here, the heat exchanging part 395 is arranged in the opening 51 formed between the upper and lower divided members 381 and 382 by the partition 386 between the ventilation path 393 and the containing area 394 on the side of the containing area 394 as shown in FIGS. 2, 4, and 5, a metal plate projecting back and forth as shown in FIGS. 2, 4, and 5, for example, an aluminum-based partition wall 52 with high corrosion resistance, is provided. By being inserted from above into a guide groove 51a formed in the mouth edge, in particular, a vertically-facing mouth edge, the end of the housing area 394 is positioned, and at the opening 51 portion of the ventilation path 393 and the housing area 394 It has a rough seal structure that suppresses airflow. The opposite end of the heat exchanging portion 395, that is, the end on the suction discharge port 392 side is the suction exhaust port 392 side of the heat exchanging portion receiving tray 393a1 of the lower divided member 382 as shown in FIGS. Between the guides 53a and 53b integrally formed upward at the front and rear corner portions of the end portion of the end portion, the guide portions 53a and 53b are roughly fitted and positioned from above. By positioning these both end portions, the heat exchanging portion 395 is positioned at a predetermined position on the heat exchanging portion receiving tray 393a1. The heat exchanging portion 395 is also provided with a rib-like partition wall 54 as shown in FIG. 8 formed downward from the partition wall 386a to the other end portion wall facing the partition wall 386a on the back surface of the ceiling wall of the upper dividing member 381. The contact prevents the heat exchange part 395 from floating from the heat exchange part receiving tray 393a1 in cooperation with the upper edge of the opening 51 of the partition part 386. At the same time, the suction introduction air on the suction introduction side is prevented from bypassing from around the heat exchange section 395 to the suction discharge side in the heat exchange area 393a.
圧縮機37は、従来、圧縮機の底部まわり3か所で側方に張り出した脚部を有し、これらの脚部を収容域394の底部にねじで締結することで設置し、このねじによる締結部に弾性吸振材を介在させることで吸振させていた設置構造に代えて、そのような脚部を省略して収容域394の底部394cの凹部394a内に弾性座体43を介し着座させることで弾性支持し、緩衝および吸振できるようにする。このような、脚部の省略により圧縮機37自体の小型化、軽量化、低コスト化が図れる。一方、脚部の省略が圧縮機37の固定が困難になるし、外部からの振動、特に脱水時の横方向の振動を受けて圧縮機37が共振することにより冷媒配管に過大な力が掛かり、結果として、配管が折れる、亀裂が入るといった現象を招くとことについては、弾性座体43を介した凹部394aへの着座による弾性支持にて圧縮機37の振動に対して吸振作用を発揮する上、脱水時の横方向の外部振動などにも高い緩衝作用を発揮する。例えば、圧縮機37は、従来平面視して140mm程度のかさ張りであったのが90mm程度に小さくなり、収容域394の必要スペースが小さくなる分、ユニットケース38は従来通りの大きさで通風路393およびそこに設置する熱交換部395を大きくして熱交換効率を高め、空調性能を高められる。   Conventionally, the compressor 37 has legs that protrude laterally at three places around the bottom of the compressor, and is installed by fastening these legs to the bottom of the receiving area 394 with screws. Instead of the installation structure that has been made to absorb vibration by interposing an elastic vibration-absorbing material in the fastening portion, such a leg portion is omitted and seated through the elastic seat 43 in the recess 394a of the bottom 394c of the receiving area 394. It is elastically supported so that it can be buffered and absorbed. By omitting the legs, the compressor 37 itself can be reduced in size, weight, and cost. On the other hand, the omission of the leg portion makes it difficult to fix the compressor 37, and the compressor 37 resonates due to external vibration, particularly lateral vibration during dehydration, and excessive force is applied to the refrigerant pipe. As a result, the phenomenon that the pipe breaks or cracks are caused, and the elastic support by the seating on the recess 394a via the elastic seat body 43 exerts a vibration absorbing action against the vibration of the compressor 37. In addition, it exhibits a high buffering effect against lateral external vibration during dehydration. For example, the compressor 37, which was previously bulky about 140 mm in plan view, is reduced to about 90 mm, and the required space for the accommodation area 394 is reduced, so that the unit case 38 has a conventional size and a ventilation path. It is possible to increase the heat exchanging efficiency by increasing the heat exchanging portion 395 and the heat exchanging portion 395 installed therein, thereby improving the air conditioning performance.
具体的には、収容域394は、ユニットケース38の下分割部材382の底部がなす既述の万が一のオーバーフロー水などに対応するための図1、図2に示すような水溜り部396、ないしはその一部となる凹部394a内に、圧縮機37をその下部に図9に示すように被せ付けた弾性座体43にて径方向の小さな隙間45を有して着座させるのに併せ、ユニットケース38の上分割部材381の上部から図1、図8に示すように下向きに突出した突起145を圧縮機37の上端に図1に示すような所定の隙間46を持って対向させ圧縮機37の凹部394aからの許容量を超える抜けを防止するようにしている。具体的には、隙間45は、例えば0.5mm程度、隙間46は、例えば5mm程度、としてある。ここに、抜けの許容量は圧縮機37に対する吸振、緩衝作用が損なわれない範囲である。   Specifically, the accommodating area 394 is a water reservoir 396 as shown in FIGS. 1 and 2 for dealing with the above-described emergency overflow water formed by the bottom of the lower dividing member 382 of the unit case 38, or In addition to being seated in the recess 394a, which is a part of the compressor 37, with the elastic seat body 43 attached to the lower portion thereof as shown in FIG. As shown in FIGS. 1 and 8, a protrusion 145 protruding downward from the upper part of the upper dividing member 381 is opposed to the upper end of the compressor 37 with a predetermined gap 46 as shown in FIG. It is intended to prevent the excess from the recess 394a from exceeding the allowable amount. Specifically, the gap 45 is about 0.5 mm, for example, and the gap 46 is about 5 mm, for example. Here, the allowable amount of omission is a range in which the vibration absorption and buffering action for the compressor 37 is not impaired.
これによって、圧縮機37は自重で弾性座体43の弾性支持力とバランスするまで弾性座体43を圧縮させて凹部394a内に落ち着き、収容域394内に径方向および上下方向に若干の遊びを持ってフローティング支持される。弾性座体43は図1、図3、図9に示すように、圧縮機37の下面外周域に対向して弾性支持する環状の脚部43aを持ち、無垢でないことにより圧縮機37の振動に対する吸振性を高めている。さらに、脚部43aは、凹部394a内に同心で浅い第2の凹部394bに下端が嵌り込むことで自身の半径方向の移動の制限を受け、圧縮機37に対する径方向の支持力を下端部で高めながらも、圧縮機37の脚部43a部を中心とする揺れを前記隙間45の分だけ幾分許容できるようにしている。弾性座体43は、さらに、図1、図4、図9に示すように脚部43aの上端に繋がって圧縮機37の下部外周にやや厚肉となって被さるキャップ部43bを有し、前記圧縮機37の揺れが前記隙間45をどの特定径方向に超えた場合でも、凹部394aの内周との間でキャップ部43bが対応する特定径方向に圧縮されるので、振動的な揺れに対する吸振作用を発揮するし、ユニットケース38に振動が伝達するときの衝突音を低減できる。しかも、キャップ部43bは、その外周に軸線方向のリブ43cが周方向に配設されていることで、前記凹部394aの内周との間での圧縮による吸振を柔軟に無理なく実行し、圧縮機37を凹部394a内の所定範囲内に位置するように弾性支持する。また、キャップ部43bは、その周壁に圧縮機37から胴部側方へ突出する配管の一部などと係合する図9、図11に仮想線で示すような係合凹部を形成しておけば、弾性座体43と圧縮機37との回り止めになる。また、弾性座体43と凹部394aとの間にも回り止めの係合部や嵌り合い部を設けることもできる。また、弾性座体43の脚部43aとキャップ部43bなど部分的に別体としてもよい。要するに、凹部394aと圧縮機37の下端部との間の空間を弾性部材で埋めていることが基本条件となる。   As a result, the compressor 37 compresses the elastic seat 43 until it balances with the elastic supporting force of the elastic seat 43 by its own weight, settles in the recess 394a, and has some play in the radial direction and the vertical direction in the accommodation area 394. Have floating support. As shown in FIGS. 1, 3, and 9, the elastic seat body 43 has an annular leg portion 43 a that elastically supports the outer peripheral area of the lower surface of the compressor 37. Improves vibration absorption. Further, the leg portion 43a is restricted in its radial movement by fitting the lower end thereof into the concentric and shallow second concave portion 394b in the concave portion 394a, and the radial support force to the compressor 37 at the lower end portion. While increasing, the swing around the leg portion 43a of the compressor 37 is allowed to be somewhat allowed by the gap 45. The elastic seat body 43 further includes a cap portion 43b which is connected to the upper end of the leg portion 43a as shown in FIGS. Even if the vibration of the compressor 37 exceeds the gap 45 in any specific radial direction, the cap portion 43b is compressed in the specific radial direction corresponding to the inner periphery of the recess 394a, so that vibration absorption for vibrational vibration is performed. The effect is exerted, and a collision sound when vibration is transmitted to the unit case 38 can be reduced. In addition, since the cap portion 43b is provided with axial ribs 43c on the outer periphery thereof, the cap portion 43b performs vibration absorption by compression with the inner periphery of the concave portion 394a flexibly and comfortably. The machine 37 is elastically supported so as to be positioned within a predetermined range in the recess 394a. Further, the cap portion 43b may be formed with an engaging recess as shown by an imaginary line in FIGS. 9 and 11 that engages with a part of the pipe protruding from the compressor 37 to the side of the body portion on the peripheral wall. Thus, the elastic seat 43 and the compressor 37 are prevented from rotating. Further, a non-rotating engaging portion or a fitting portion can also be provided between the elastic seat body 43 and the concave portion 394a. Further, the leg portion 43a and the cap portion 43b of the elastic seat 43 may be partially separated. In short, the basic condition is that the space between the recess 394a and the lower end of the compressor 37 is filled with an elastic member.
収容域394は、また、凹部394aを形成している底部394cを図1に示すように、熱交換部受載皿393a1および吸引排出側393a2の底部よりも少し高く設定して、収容域394側と通風路393側とを区画部386により熱交換部395を挟持する開口51周りで区画し、開口51の口縁の下部に凹条を設けて収容域394側を通風路393側の分離水排水皿23に繋ぐ、具体的には連通路27を介し繋ぐ、連通路47を底部394cの熱交換部395の下に形成してある。これに併せ、底部394cには凹部394aの内周壁を上方に延長した図1、図2、図4、図6に示すようなほぼ環状のリブ48を形成してある。さらに、圧縮機37まわりの低温配管37aからの結露水滴下部に前記底部394cの一部が対応し、滴下する結露水を受け止めるようにしている。この結果、低温配管37aから運転中少量であっても定常的に滴下する結露水は、凹部394aまわりの底部394cに受け止められ、区画部386の開口51における開口縁下部に底部394cと同レベルで形成した連通路47を通じ、底部394aよりも低い分離水排水皿23に流れ落ちることで、分離水と共に自然排水され、凹部394a内へはリブ48により邪魔されて流れ込むことはない。従って、従来の脚部付き圧縮機では、脚部を弾性部材を介し締結する部分に対し、圧縮機の下端部と対向する部分は圧縮機の下端部を浮かせるための凹部を持つことが必須となり、その凹部に圧縮機の低温配管から定常的に滴下する結露水が溜まることにつき、排水穴を設けて対応していたが、送風ファン15を運転したときに通風路393側からの吸引が収容域394に及ぶとこの穴を通じ外部空気を導入することになり、特に低温時の乾燥効率が悪化する問題があるし、通風路393、収容域394双方間のシール性能を高める必要がある上、定常的に滴下してくる穴からの排水を通常排水系に導く排水系が別途必要となる。しかし、前記のように、収容域394の底部394cに滴下する結露水を、通風路393と収容域394との間のシールが不要なことを利用し設けた連通路47を通じ専ら分離水排水皿23に排水することで、圧縮機37を着座させる凹部394aに排水穴は不要で排水経路を削減できるし、外気を吸引することはないので低温時での乾燥効率を低下させるような問題は生じない。   As shown in FIG. 1, the storage area 394 is set so that the bottom 394c forming the recess 394a is slightly higher than the bottoms of the heat exchanger receiving tray 393a1 and the suction / discharge side 393a2. And the ventilation path 393 side are partitioned around the opening 51 sandwiching the heat exchanging part 395 by the partitioning part 386, and a recess is provided at the lower part of the lip of the opening 51 to separate the separated water on the ventilation path 393 side. A communication passage 47 connected to the drainage tray 23, specifically, the communication passage 27, is formed under the heat exchanging portion 395 of the bottom portion 394c. At the same time, a substantially annular rib 48 as shown in FIGS. 1, 2, 4, and 6 is formed on the bottom 394c by extending the inner peripheral wall of the recess 394a upward. Further, a part of the bottom portion 394c corresponds to the dew condensation water dropping portion from the low temperature pipe 37a around the compressor 37 so as to receive the dew condensation water. As a result, the condensed water that steadily drops from the low temperature pipe 37a during operation is received by the bottom 394c around the recess 394a, and at the same level as the bottom 394c at the lower portion of the opening edge of the opening 51 of the partition 386. By flowing down to the separated water drain tray 23 lower than the bottom portion 394a through the formed communication passage 47, it is naturally drained together with the separated water, and does not flow into the recess portion 394a by being obstructed by the rib 48. Therefore, in a conventional compressor with legs, it is essential that the portion facing the lower end of the compressor has a recess for floating the lower end of the compressor, relative to the portion where the leg is fastened through the elastic member. The condensate that is constantly dripping from the low-temperature piping of the compressor has been provided with a drain hole in the recess, but when the blower fan 15 is operated, suction from the ventilation path 393 side is accommodated. If it reaches the area 394, external air will be introduced through this hole, and there is a problem that the drying efficiency is deteriorated particularly at a low temperature, and it is necessary to improve the sealing performance between the ventilation path 393 and the accommodation area 394. A separate drainage system for guiding drainage from the constantly dripping hole to the normal drainage system is required. However, as described above, the dewatered water that drops on the bottom portion 394c of the storage area 394 is exclusively separated through the communication passage 47 provided by utilizing the fact that the seal between the ventilation path 393 and the storage area 394 is unnecessary. By draining to 23, there is no need for a drainage hole in the recess 394a on which the compressor 37 is seated, and the drainage path can be reduced, and since no outside air is sucked in, there is a problem of reducing the drying efficiency at low temperatures. Absent.
ところで、既述した、熱交換部395のユニットケース38の長手方向に対する斜め配置によっても、下流の送風ファン15から吸引排出口392に及ぶ吸引作用は、熱交換部395の前部に向く排気面395b全域に対して、吸引排出口392に近い側に強く働くことに変わりはない。このため、熱交換域393aの吸引排出側では、熱交換部395の前向き排気面395bの吸引排出口392に近い側から、蒸発器31を通過する際に生じた結露水を排気面395b側に吸い出し、吸引排出口392を通じ送風ファン15に吸い込んでしまう心配がある。これに対応するのに、本実施の形態では、さらに、図1、図4、図7、図10に示すように、熱交換部受載皿393a1の吸引排出口392側端部の前部側で上方に延びるガイド53aを利用して、吸引排出口392からの強い吸引作用による結露水の吸引を邪魔する遮蔽壁56を形成している。特に、この強い吸引作用の片寄りは、吸引排出口392に接続した送風ファン15が図13に示すような渦巻ケーシング15bを持ち、その吹き出し部15dが後部で上向きに立ち上がる位置関係で設けられて、熱交換部395の排出面395bの吸引排出口392側端縁の下半部と下端縁の前部側とに沿ったコーナ部となることに対応して、遮蔽壁56は図1、図7、図11示すようにガイド53aを含み階段状に形成した単純形状にて熱交換部395の排出面395bを必要最小限に覆うことができる。一方、遮蔽壁56ができるだけ排出面395bの通風面積を狭めないために、ガイド53aからの張り出し部56aを排出面395bから図4に示すように浮かせている。これに併せ、送風ファン15のファン15aと同心な吸引排出口392において、その遮蔽壁56による吸い込み制限側は、図7に示すように吸引排出口392のファン15aの軸線まわりの円形形状を狭める縦向きの直線縁392bを有して軸線側に張り出した形状とし、熱交換部395の吸引排出口392側端部からの水の吸い込みを防止しやすくしている。同様に、吸引排出口392の下縁も熱交換部受載皿393a1と同じ高さまで軸線に向け上方に狭める横向き直線縁392cに形成し、貯留部63底部からの水分の吸い込みを制限している。   By the way, also by the diagonal arrangement with respect to the longitudinal direction of the unit case 38 of the heat exchange part 395 described above, the suction action from the downstream blower fan 15 to the suction / discharge port 392 is the exhaust surface facing the front part of the heat exchange part 395. There is no change in acting strongly on the side close to the suction / discharge port 392 with respect to the entire area 395b. For this reason, on the suction / discharge side of the heat exchange area 393a, the dew condensation water generated when passing through the evaporator 31 from the side close to the suction / discharge port 392 of the forward exhaust surface 395b of the heat exchange unit 395 to the exhaust surface 395b side. There is a concern that the air is sucked out and sucked into the blower fan 15 through the suction discharge port 392. To cope with this, in the present embodiment, as shown in FIG. 1, FIG. 4, FIG. 7, and FIG. 10, the front side of the end portion on the suction discharge port 392 side of the heat exchanging portion receiving tray 393a1 A shielding wall 56 that obstructs the suction of condensed water by a strong suction action from the suction / discharge port 392 is formed by using a guide 53a extending upward. In particular, the side of this strong suction action is provided in such a positional relationship that the blower fan 15 connected to the suction / discharge port 392 has a spiral casing 15b as shown in FIG. 13 and the blowing part 15d rises upward at the rear part. The shielding wall 56 corresponds to the corner portion along the lower half of the end edge on the suction discharge port 392 side of the discharge surface 395b of the heat exchange portion 395 and the front side of the lower end edge. 7. As shown in FIG. 11, the discharge surface 395b of the heat exchanging portion 395 can be covered to the minimum necessary with a simple shape including a guide 53a and formed in a stepped shape. On the other hand, in order to prevent the shielding wall 56 from reducing the ventilation area of the discharge surface 395b as much as possible, the protruding portion 56a from the guide 53a is floated from the discharge surface 395b as shown in FIG. At the same time, in the suction / discharge port 392 concentric with the fan 15a of the blower fan 15, the suction restriction side by the shielding wall 56 narrows the circular shape around the axis of the fan 15a of the suction / discharge port 392 as shown in FIG. It has a shape that has a vertical straight edge 392b and protrudes to the axial line side, so that it is easy to prevent the suction of water from the end of the heat exchange unit 395 on the suction / discharge port 392 side. Similarly, the lower edge of the suction / discharge port 392 is also formed as a horizontal straight edge 392c that narrows upward toward the axis up to the same height as the heat exchanging portion receiving tray 393a1, and restricts the suction of moisture from the bottom of the storage portion 63. .
ユニットケース38の吸引排出口392と送風ファン15との接続は、図1に示すように、ファン15aを収容した渦巻ケーシング15bの吸引口15cの接続筒15c1を吸引排出口392の内周に遊びを持って嵌め合わせながら、接続筒15c1の先端を吸引排出口392の内周のフランジ壁392aに圧接させて、渦巻ケース15bとユニットケース38とを吸引排出口392、吸引口15cの接続部まわり複数個所、例えば3か所以上でのねじ締結などした連結部62を設けて前記圧接状態を保持することにより、接続部を簡易にシールしている。これにより、消耗品となるシール部材が省略でき製品コスト、ランニングコスト共に低減する。   As shown in FIG. 1, the connection between the suction discharge port 392 of the unit case 38 and the blower fan 15 is free from the connection cylinder 15c1 of the suction port 15c of the spiral casing 15b containing the fan 15a on the inner periphery of the suction discharge port 392. The tip of the connection tube 15c1 is pressed against the flange wall 392a on the inner periphery of the suction / discharge port 392, and the spiral case 15b and the unit case 38 are connected around the connection portion of the suction / discharge port 392 and the suction port 15c. By connecting portions 62 that are screwed at a plurality of locations, for example, at three or more locations, and maintaining the pressure contact state, the connection portions are simply sealed. Thereby, the seal member which becomes a consumable can be omitted, and both the product cost and the running cost are reduced.
なお、ユニットケース38は3つの分割部材で構成すれば、それぞれの成形品ボリュームが小さくなる利点があり、複雑な形状にも対応しやすくなる。図示例に適用する場合、図11を参照して説明すれば、例えば、上部分割部材381において、熱交換域303a1の天井壁以下の部分と、それより高い部分、つまり上向き拡張域393d、吸引導入口391および収容域394の上部を図11に仮想線で示すような単純な水平面上でユニットケース38外面に臨んだ割線61を有して分割し、この割線61間の全周に連続したシール部材を介在させてユニットケース38内外をシールすれば、2分割構造の上記実施の形態の場合の特長を損なうことなく、3つの分割部材で構成したことによる特長が得られる。   If the unit case 38 is composed of three divided members, there is an advantage that the volume of each molded product is reduced, and it is easy to cope with a complicated shape. When applied to the illustrated example, with reference to FIG. 11, for example, in the upper divided member 381, the portion below the ceiling wall of the heat exchange region 303 a 1 and the higher portion, that is, the upward expansion region 393 d, suction introduction The upper portion of the mouth 391 and the accommodation area 394 is divided with a split line 61 facing the outer surface of the unit case 38 on a simple horizontal plane as shown by phantom lines in FIG. If the inside and outside of the unit case 38 are sealed with a member interposed therebetween, the advantages of the configuration of the three divided members can be obtained without impairing the features of the above-described embodiment of the two-divided structure.
