(実施の形態1)
図1は、本発明の第1の実施の形態における衣類乾燥機の断面図、図2は、本発明の第1の実施の形態における衣類乾燥機の設置図である。
(Embodiment 1)
FIG. 1 is a cross-sectional view of a clothes dryer according to the first embodiment of the present invention, and FIG. 2 is an installation diagram of the clothes dryer according to the first embodiment of the present invention.

本体21の内部には、複数のサスペンション22によって弾性的に支持された円筒状の外槽23を設け、乾燥時の振動をサスペンション22によって吸収する。外槽23の内部には、衣類を収容する円筒状の内槽24を回転可能に設け、モータ(駆動手段)25により回転駆動される。外槽23は衣類の乾燥室となる。   A cylindrical outer tub 23 elastically supported by a plurality of suspensions 22 is provided inside the main body 21, and vibrations during drying are absorbed by the suspensions 22. A cylindrical inner tub 24 for storing clothes is rotatably provided inside the outer tub 23, and is rotated by a motor (driving means) 25. The outer tub 23 is a clothes drying chamber.

本体21の前面には衣類を出し入れする衣類投入口26と、これを開閉する開閉扉27が設けられている。外槽23および内槽24の前面側にも同様の開口部23a、24aを有し、この外槽23の開口部23aはゴム製のベローズ28によって本体21の衣類投入口26と気密に連結されている。送風手段29は、モータ29aとファン29bで構成され、図1に示すように本体21の後方に設けられている。   On the front surface of the main body 21, there are provided a clothing insertion port 26 through which clothes are put in and out and an opening / closing door 27 that opens and closes the clothing. Similar openings 23a, 24a are also provided on the front side of the outer tub 23 and the inner tub 24, and the opening 23a of the outer tub 23 is airtightly connected to the clothing inlet 26 of the main body 21 by a rubber bellows 28. ing. The blower means 29 includes a motor 29a and a fan 29b, and is provided behind the main body 21 as shown in FIG.

送風手段29は、内槽24及び外槽23を通過してきた空気を外槽23の下方に設けられた吸込み口30から吸込み、外槽23の背面に設けられた供給口31へと導出する。衣類投入口26と供給口31の位置関係は、同軸上が望ましく、供給口31から排出された乾燥空気が直接衣類投入口26から噴出するように、供給口31を可能な限り衣類投入口26の中心近くに設けている。本体21の背面の空きスペースには、ヒートポンプ装置32を構成する圧縮機33、膨張機構34、吸熱器35及び放熱器36が配設されている。循環風路37は、送風手段29により送風される空気を矢印の方向に吸熱器35から放熱器36へと流すためのものであり、吸熱器35、送風手段29、放熱器36を並べて内部に収容している。循環風路37の入口側は吸込み口30と連通され、出口側は供給口31と連通されている。   The air blowing means 29 sucks air that has passed through the inner tub 24 and the outer tub 23 from a suction port 30 provided below the outer tub 23 and guides it to a supply port 31 provided on the back surface of the outer tub 23. The positional relationship between the clothing input port 26 and the supply port 31 is preferably coaxial, and the supply port 31 is placed as much as possible in the clothing input port 26 so that dry air discharged from the supply port 31 is directly ejected from the clothing input port 26. It is provided near the center. A compressor 33, an expansion mechanism 34, a heat absorber 35, and a heat radiator 36 constituting the heat pump device 32 are disposed in an empty space on the back surface of the main body 21. The circulation air passage 37 is for flowing the air blown by the blowing means 29 from the heat absorber 35 to the radiator 36 in the direction of the arrow, and the heat absorber 35, the blowing means 29, and the radiator 36 are arranged inside. Contained. The inlet side of the circulation air passage 37 communicates with the suction port 30, and the outlet side communicates with the supply port 31.

衣類を乾燥する時は、送風手段29で送風される乾燥用空気は、図1の矢印に示すように、吸込み口30を通り循環風路37内の吸熱器35及び放熱器36を通過した後、供給口31から外槽23及び内槽24内に入り、内槽24内の衣類を通過した後、吸込み口30を通って再び送風手段29へと戻り循環するようになっている。   When drying clothes, the drying air blown by the blowing means 29 passes through the suction port 30 and the heat absorber 35 and the radiator 36 in the circulation air passage 37 as shown by the arrows in FIG. Then, after entering the outer tub 23 and the inner tub 24 from the supply port 31 and passing through the clothing in the inner tub 24, it returns to the blowing means 29 through the suction port 30 and circulates again.

外槽23の吸込み口30と循環風路37の入口とは、蛇腹状の伸縮可能な可撓性材料からなる吸込みホース37aを介して連通し、循環風路37の出口と供給口31も同様に、蛇腹状の伸縮可能な可撓性材料からなる供給ホース37bを介して連通しており、外槽23の振動がヒートポンプ装置32へと伝達されることを防いでいる。また、循環風路37の下部には、吸熱器35からの除湿水を貯めるドレン水容器37cが設けられており、ドレン水容器37cに貯まった水は排出口(図示せず)から本体21外へと排出される。   The suction port 30 of the outer tub 23 and the inlet of the circulation air passage 37 communicate with each other via a suction hose 37a made of a bellows-like stretchable flexible material, and the outlet of the circulation air passage 37 and the supply port 31 are the same. In addition, it communicates via a supply hose 37 b made of a bellows-like stretchable flexible material, and the vibration of the outer tub 23 is prevented from being transmitted to the heat pump device 32. Further, a drain water container 37c for storing dehumidified water from the heat absorber 35 is provided at the lower part of the circulation air passage 37, and the water stored in the drain water container 37c is discharged from the main body 21 through a discharge port (not shown). Is discharged.

また、ヒートポンプ装置32は、圧縮機33、および圧縮された冷媒の熱を放熱する放熱器36、および高圧の冷媒の圧力を減圧するための絞り弁や毛細管等からなる膨張機構34、および減圧されて低圧となった冷媒が周囲から熱を奪う吸熱器35とを冷媒が循環するように管路38で連結されている。矢印の方向に流れて循環し、ヒートポンプサイクルを実現する。また、制御手段39はモータ25や送風手段29及び圧縮機33等を表示設定手段40の設定内容に基づいて駆動して乾燥を制御する。図2に示すように衣類乾燥機の設置場所は、一般的に浴室の脱衣場となっている。   In addition, the heat pump device 32 includes a compressor 33, a radiator 36 that radiates heat of the compressed refrigerant, an expansion mechanism 34 that includes a throttle valve, a capillary tube, and the like for reducing the pressure of the high-pressure refrigerant, and a reduced pressure. The refrigerant having a low pressure is connected by a pipe line 38 so that the refrigerant circulates through the heat absorber 35 that takes heat from the surroundings. Flows in the direction of the arrow and circulates to realize a heat pump cycle. Further, the control means 39 controls the drying by driving the motor 25, the air blowing means 29, the compressor 33 and the like based on the setting contents of the display setting means 40. As shown in FIG. 2, the clothes dryer is generally installed in a bathroom dressing room.

以上のような構成において、次に、この動作について説明する。室内乾燥工程では、開閉扉27を開放し、ヒートポンプ装置32の圧縮機33を作動させると、冷媒が圧縮され、この圧力により放熱器36、膨張機構34、吸熱器35を循環する。放熱器36では冷媒の圧縮で熱が放出され、吸熱器35では膨張機構34で減圧されて低圧となった冷媒により熱が吸収される。このとき送風手段29が作動し、放熱器36の放熱により加熱された温風が供給口31を通って外槽23及び内槽24内に送風され、衣類投入口26より本体21の外に排出される。   Next, the operation of the above configuration will be described. In the indoor drying process, when the open / close door 27 is opened and the compressor 33 of the heat pump device 32 is operated, the refrigerant is compressed, and the pressure circulates through the radiator 36, the expansion mechanism 34, and the heat absorber 35. In the radiator 36, heat is released by the compression of the refrigerant, and in the heat absorber 35, the heat is absorbed by the refrigerant whose pressure is reduced by the expansion mechanism 34. At this time, the air blowing means 29 is activated, and the warm air heated by the heat radiation of the radiator 36 is blown into the outer tub 23 and the inner tub 24 through the supply port 31, and is discharged out of the main body 21 from the clothing input port 26. Is done.

一方、室内の湿った空気は外槽23の吸込み口30から循環風路37に至る。この湿った空気は、吸熱器35を通過する際に顕熱と潜熱が奪われて除湿され、乾いた空気と除湿水に分離される。この乾いた空気は、放熱器36で再び加熱され温風となる。吸熱器35で結露した除湿水は、ドレン水容器37cに貯まり、排出口から機外へ排出される。上記動作を繰り返すことにより、室内の除湿乾燥を進行させる。   On the other hand, the humid air in the room reaches the circulation air passage 37 from the suction port 30 of the outer tub 23. When this moist air passes through the heat absorber 35, sensible heat and latent heat are taken away and dehumidified, and separated into dry air and dehumidified water. This dry air is heated again by the radiator 36 and becomes warm air. The dehumidified water dewed by the heat absorber 35 is stored in the drain water container 37c and discharged from the discharge port to the outside of the apparatus. By repeating the above operation, the dehumidification drying in the room is advanced.

以上のように、内槽24を駆動する駆動手段25と、乾燥用空気を供給する送風手段29を別々に設けたことにより内槽24内に供給された除湿後の空気を衣類投入口26より本体21の外へ排気する時は内槽24の回転を停止することができ、内槽24の駆動エネルギと内槽24の回転騒音を無くすことができる。   As described above, by providing the driving means 25 for driving the inner tub 24 and the air blowing means 29 for supplying the drying air separately, the dehumidified air supplied into the inner tub 24 is supplied from the clothing inlet 26. When exhausting out of the main body 21, the rotation of the inner tank 24 can be stopped, and the driving energy of the inner tank 24 and the rotational noise of the inner tank 24 can be eliminated.

また、浴室は湿気が多く、特に梅雨時はカビの発生が問題となっており、浴室の扉を閉めて密閉空間にし、除湿機を駆動して乾燥を行うことが多かった。しかし、ながら浴室は一般的に狭く、単機能の除湿機を置くと更に狭くなり使い勝手が悪くなっていた。衣類乾燥機に室内乾燥機能を付加することで、浴室を狭くすることなく除湿乾燥することができる。   Also, the bathroom is humid, and mold generation is a problem especially during the rainy season, and the bathroom door is closed to a sealed space, and the dehumidifier is driven to dry. However, the bathroom is generally narrow, and when a single-function dehumidifier is placed, it becomes even narrower and unusable. By adding an indoor drying function to the clothes dryer, the clothes dryer can be dehumidified and dried without narrowing the bathroom.

また、本実施の形態ではドレン水容器37c内の除湿水を排出する手段として排出口を設けているが、排水ポンプを設けて水を排出するようにしても良い。   In this embodiment, a discharge port is provided as a means for discharging the dehumidified water in the drain water container 37c. However, a drain pump may be provided to discharge water.

(実施の形態2)
図3は、本発明の第2の実施の形態における衣類乾燥機の断面図である。なお、第1の実施の形態と同一構成要件は同一符号を付して詳細な説明は省略する。
(Embodiment 2)
FIG. 3 is a cross-sectional view of a clothes dryer according to the second embodiment of the present invention. The same constituent elements as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

図3に示すように、吸熱器35の上流側の循環風路37に外気を導入する吸気口41と、吸気口41を開閉する吸気弁42を設けている。吸気弁42は開閉モータ42aにより、吸気口41と循環風路37を選択的に切り替えるようにしている。開閉モータ42aを駆動して吸気弁42を動かし、吸気口41を開いて循環風路37を閉じると、吸気口41から湿った外気が導入される。この湿った外気は、吸熱器35を通過する際に顕熱と潜熱が奪われて除湿され、乾いた空気と除湿水に分離される。この乾いた空気は、放熱器36で加熱され温風となって供給口31から外槽23、内槽24へと供給される。   As shown in FIG. 3, an intake port 41 that introduces outside air into the circulation air passage 37 upstream of the heat absorber 35 and an intake valve 42 that opens and closes the intake port 41 are provided. The intake valve 42 selectively switches between the intake port 41 and the circulation air passage 37 by an opening / closing motor 42a. When the opening / closing motor 42a is driven to move the intake valve 42, the intake port 41 is opened and the circulation air passage 37 is closed, moist outside air is introduced from the intake port 41. When the wet outside air passes through the heat absorber 35, the sensible heat and latent heat are taken away and the dehumidified air is separated into dry air and dehumidified water. The dry air is heated by the radiator 36 and is supplied as warm air from the supply port 31 to the outer tub 23 and the inner tub 24.

内槽24内に供給された乾燥空気は、循環風路37が閉じているので吸入口30から吸引されること無く全て衣類投入口26より本体21外へ排気されることになる。これにより、除湿後の空気の一部が循環風路37に戻ることがなくなるので、除湿後の空気を全て室内乾燥に利用することができ、更に効率よく室内を乾燥することができる。   The dry air supplied into the inner tub 24 is exhausted out of the main body 21 from the clothing inlet 26 without being sucked from the inlet 30 because the circulation air passage 37 is closed.
