従来、衣類を洗濯乾燥する機器としてはヒータを熱源にするものや、ヒートポンプ装置を熱源に用いたものがある(例えば、特許文献1参照)。図8は、前記公報に記載された洗濯乾燥機の側断面図である。   Conventionally, as a device for washing and drying clothes, there are a device using a heater as a heat source and a device using a heat pump device as a heat source (see, for example, Patent Document 1). FIG. 8 is a side sectional view of the washing / drying machine described in the publication.
図8において、洗濯乾燥機1は、ケーシング2をもち、同ケーシング2の中央に衣類6を出し入れするためのドア12が取付けられており、内部には回転ドラム3が収納されている。同回転ドラム3の所定の部位には衣類6を回転ドラム3の回転とともに持ち上げ落下させるためのビータ5と、洗濯水7および乾燥のための循環エア9が出入りするパンチング孔4が開口してある。回転ドラム3のシャフト11は、図示されない駆動用モータか
ら回転のための動力を受けるようになっている。
In FIG. 8, the washing and drying machine 1 has a casing 2, and a door 12 for attaching and removing clothes 6 is attached to the center of the casing 2, and a rotating drum 3 is accommodated therein. A predetermined portion of the rotating drum 3 has a beater 5 for lifting and dropping the clothes 6 along with the rotation of the rotating drum 3, and a punching hole 4 through which washing water 7 and circulating air 9 for drying enter and exit. . The shaft 11 of the rotating drum 3 receives power for rotation from a driving motor (not shown).
また、ケーシング2内の回転ドラム3の背面は、空気入口24および空気出口23を除き隔壁22によって仕切られ、循環エア9が通るダクト10、13が形成されている。前記隔壁22の前面下部は洗濯槽14を構成し、同洗濯槽14の部分に回転ドラム3の下部が臨んでいる。   Further, the back surface of the rotating drum 3 in the casing 2 is partitioned by a partition wall 22 except for the air inlet 24 and the air outlet 23, and ducts 10 and 13 through which the circulating air 9 passes are formed. The lower part of the front surface of the partition wall 22 constitutes a washing tub 14, and the lower part of the rotating drum 3 faces the portion of the washing tub 14.
前記各エアダクト10、13にはコンプレッサ19、凝縮器(コンデンサ)18、ファン17、膨脹弁20、蒸発器(エバポレータ)15等が内蔵されており、いわゆるヒートポンプサイクルが形成されている。また、コンデンサ18の一部はケーシング外背面に延長され、放熱器16を形成している。21はドレン排水用配管、8は洗濯排水用配管である。   Each of the air ducts 10 and 13 incorporates a compressor 19, a condenser (condenser) 18, a fan 17, an expansion valve 20, an evaporator (evaporator) 15 and the like, and a so-called heat pump cycle is formed. Further, a part of the capacitor 18 is extended to the outer back surface of the casing to form a radiator 16. 21 is a drain drain pipe, and 8 is a washing drain pipe.
次に、各工程と作用について説明する。洗濯、すすぎ工程は、ドア12をあけて衣類6および適量の洗剤を投入し、ドア12を閉め、以下の工程を実行する。   Next, each process and operation will be described. In the washing and rinsing process, the door 12 is opened, the garment 6 and an appropriate amount of detergent are put in, the door 12 is closed, and the following processes are executed.
水供給バルブ(図示せず)から洗濯槽14に水位Aの位置まで規定量の水7が供給される。回転ドラム3がプログラムされた回転数で連続または間欠的に回転し、洗浄が行なわれる。この間、衣類6はビータ5によって持ち上げられ落下する。洗濯終了後は、洗濯槽14の洗濯排水用配管8から機外に排水される。続いて、すすぎ工程が同様の工程で実行される。すすぎ水も洗濯排水として洗濯排水用配管8から機外に排水される。   A prescribed amount of water 7 is supplied from a water supply valve (not shown) to the washing tub 14 up to the position of the water level A. The rotating drum 3 rotates continuously or intermittently at the programmed number of rotations to perform cleaning. During this time, the garment 6 is lifted and dropped by the beater 5. After washing is completed, the water is drained out of the machine from the washing drain pipe 8 of the washing tub 14. Subsequently, the rinsing process is performed in the same process.

Japanese Unexamined Patent Publication No. 1-332893
しかしながら、前記従来の構成では、ドレン排水用配管21と洗濯排水用配管8が別個に排水を機外に導いている。洗濯機においては上記排水用配管に相当する排水ホースは1本であり、洗濯機の設置場所に洗濯乾燥機を設置する場合などは、従来と同様に1つの排水ホースで排水処理ができることが、設置作業や防水フロアーなどの設置部材や床下の配管設備の面で望ましい。   However, in the conventional configuration, the drain drain pipe 21 and the washing drain pipe 8 separately lead the drain to the outside of the machine. In the washing machine, there is one drainage hose corresponding to the drainage pipe, and when a washing / drying machine is installed at the place where the washing machine is installed, the drainage treatment can be performed with one drainage hose as in the past. It is desirable in terms of installation work, installation members such as a waterproof floor, and piping equipment under the floor.
ドレン排水用配管21と洗濯排水用配管8をそのまま機内で接続すると、洗濯中に洗濯槽14に溜められる水の水位が高く、洗濯排水中に水圧によって洗濯排水用配管8からドレン排水用配管21へ洗濯水やすすぎ水が流れ込み、配管だけでなく、除湿や加熱を行うエバポレータ15やファン17やコンデンサ18などの各手段の設置位置が洗濯水の貯水水位よりも低い場合には、これら各手段が洗剤や漂白剤などが溶けた洗濯水に濡れる恐れがあるという課題を有していた。   If the drain drain pipe 21 and the laundry drain pipe 8 are directly connected in the machine, the level of water stored in the washing tub 14 during washing is high, and the drain drain pipe 21 from the laundry drain pipe 8 due to water pressure during washing drainage. When washing water and rinsing water flow into the water and the installation position of each means such as the evaporator 15, the fan 17 and the condenser 18 for performing dehumidification and heating is lower than the stored water level of the washing water as well as the piping. However, there is a problem that there is a risk of getting wet with washing water in which detergent or bleach is dissolved.
また、これを防止するためには、洗濯排水用配管8に設ける排水弁以外に、ドレン排水用配管21への逆流を防止するための逆止弁や、ドレン排水用配管21用排水弁などによる逆流防止手段が別途必要となるという課題を有していた。   In order to prevent this, in addition to the drainage valve provided in the washing drainage pipe 8, a check valve for preventing a backflow to the drainage drainage pipe 21 or a drainage valve for the drainage drainage pipe 21 is used. There has been a problem that a separate backflow prevention means is required.
本発明は、上記従来の課題を解決するもので、ドレン排水用配管21への逆流を防止するとともに、1つの排水管で機外に排水できる排水処理手段を実現することを目的とするものである。   The present invention solves the above-described conventional problems, and aims to realize a wastewater treatment means that can prevent backflow to the drain drainage pipe 21 and drain the water outside the machine with a single drainage pipe. is there.
上記の目的を達成するために本発明は、洗濯槽から所定量を超えた洗濯水を排出する溢水口と、乾燥用空気から湿気を結露水として回収する除湿手段で回収された結露水を流す結露排水路を有し、前記結露排水路の一部を前記溢水口より高位に配設し、前記結露排水路を前記排水弁よりも下流の排水管に接続し、洗濯水排水時は前記排水弁を開とし、乾燥時は前記排水弁を閉としたたものである。   In order to achieve the above-mentioned object, the present invention flows the dew condensation water collected by an overflow outlet for discharging washing water exceeding a predetermined amount from the washing tub and dehumidifying means for collecting moisture from the drying air as dew condensation water. A condensation drainage channel, a part of the condensation drainage channel is disposed higher than the overflow port, the condensation drainage channel is connected to a drainage pipe downstream of the drainage valve, and the drainage is performed when washing water is drained. The valve is opened and the drain valve is closed during drying.
これにより、洗濯水の排水開始直後の水位による水圧が結露排水路に加わって結露排水路内の水位が上昇しても、また、給水弁や水位センサなどの異常による洗濯水の水位上昇が発生しても、溢水口よりも水位が上昇することがなく、結露排水路の一部がこの溢水口よりも高位に配設されているため、これを乗り越えて洗濯水が除湿手段など各手段まで逆流することがない。よって、1つの排水管で洗濯水も結露水も機外に排水することができる。   As a result, even if the water pressure due to the water level immediately after the start of washing water drainage is applied to the condensation drainage channel and the water level in the condensation drainage channel rises, the water level of the washing water rises due to abnormalities in the water supply valve, water level sensor, etc However, the water level does not rise higher than the overflow outlet, and a part of the condensation drainage channel is located higher than the overflow outlet. There is no backflow. Accordingly, both the washing water and the dew condensation water can be drained out of the machine with one drain pipe.
また、結露排水路を排水弁よりも下流の排水管に接続し、洗濯水排水時は排水弁を開とし、乾燥時は排水弁を閉としたことにより、特に乾燥時に、結露水を確実に排水管から排水できる。   In addition, by connecting the condensation drainage channel to a drain pipe downstream from the drainage valve, the drainage valve is opened when washing water is drained, and the drainage valve is closed when drying, so that dew condensation water is ensured especially during drying. Can drain from drain pipe.
以上のように本発明の請求項1に記載の発明によれば、洗濯水の排水開始直後の水位による水圧が結露排水路に加わって結露排水路内の水位が上昇しても、また、給水弁や水位センサなどの異常による洗濯水の水位上昇が発生しても、溢水口よりも水位が上昇することがなく、結露排水路の一部もしくは除湿手段などの各手段全体がこの溢水口よりも高位に配設されているため、これを乗り越えて洗濯水が除湿手段など各手段まで逆流することがない。よって、1つの排水管で機外に排水できる簡便な排水処理を実現することができる。   As described above, according to the first aspect of the present invention, even when the water pressure due to the water level immediately after the start of drainage of the washing water is applied to the condensation drainage channel and the water level in the condensation drainage channel rises, Even if the wash water level rises due to an abnormality such as a valve or water level sensor, the water level does not rise above the overflow port. Since it is disposed at a high level, the washing water does not flow back to each means such as the dehumidifying means. Therefore, it is possible to realize a simple wastewater treatment that can be drained outside the apparatus with a single drainage pipe.
請求項1に記載の発明は、洗濯水を満たす洗濯槽と、前記洗濯槽から所定量を超えた洗濯水を排出する溢水口と、前記洗濯槽内の洗濯水を流す排水管と、乾燥用空気から湿気を結露水として回収する除湿手段と、前記除湿手段で回収された結露水を流す結露排水路と、前記結露排水路を通じて結露水を前記排水管に送る排水ポンプと、前記洗濯槽内の洗濯水を前記排水管を通じ機外に排水する排水弁と、前記排水弁と前記排水ポンプを制御する制御手段とを具備し、前記結露排水路の一部を前記溢水口より高位に配設するとともに、前記結露排水路を前記排水弁よりも下流の排水管に接続し、洗濯水排水時は前記排水弁を開とし、乾燥時は前記排水弁を閉としたものであり、洗濯水の排水開始直後の水位による水圧が結露排水路に加わって結露排水路内の水位が上昇しても、また、給水弁や水位センサなどの異常による洗濯水の水位上昇が発生しても、溢水口よりも水位が上昇することがなく、結露排水路の一部がこの溢水口よりも高位に配設されているため、これを乗り越えて洗濯水が除湿手段など各手段まで逆流することがない。よって、1つの排水管で洗濯水も結露水も機外に排水することができる。 The invention according to claim 1 is a washing tub that fills with washing water, an overflow outlet that discharges washing water that exceeds a predetermined amount from the washing tub, a drain pipe that flows the washing water in the washing tub, and a drying tub A dehumidifying means for collecting moisture from the air as condensed water, a dewatering drainage channel for passing the condensed water collected by the dehumidifying unit, a drainage pump for sending the condensed water to the drainage pipe through the condensation drainage channel, and the inside of the washing tub A drain valve for draining the washing water outside the machine through the drain pipe, and a control means for controlling the drain valve and the drain pump, and a part of the condensation drainage channel is disposed higher than the overflow port In addition, the condensation drainage channel is connected to a drain pipe downstream from the drain valve, the drain valve is opened when washing water is drained, and the drain valve is closed when drying. Water pressure due to the water level immediately after the start of drainage is added to the condensation drainage channel, Even if the water level in the drainage channel rises, or even if the washing water level rises due to an abnormality such as a water supply valve or a water level sensor, the water level does not rise above the overflow outlet, and one of the condensation drainage channels Since the portion is disposed higher than the overflow port, the washing water does not flow back to each means such as the dehumidifying means. Accordingly, both the washing water and the dew condensation water can be drained out of the machine with one drain pipe.
また、結露排水路を排水弁よりも下流の排水管に接続し、洗濯水排水時は排水弁を開とし、乾燥時は排水弁を閉としたことにより、特に乾燥時に、結露水を確実に排水管から排水できる。   In addition, by connecting the condensation drainage channel to a drain pipe downstream from the drainage valve, the drainage valve is opened when washing water is drained, and the drainage valve is closed when drying, so that dew condensation water is ensured especially during drying. Can drain from drain pipe.

47は洗濯時の排水を流す洗濯排水路で、この洗濯排水路47には排水弁60がある。48は乾燥時に吸熱器38で発生した結露水を流す結露排水路で、51は結露水を結露排水路48へ送る排水ポンプ、洗濯排水路47と結露排水路48は一つの排水管49につながれている。排水管49の先端50は機外の大気中に開口している。排水弁60と排水ポンプ51を制御する制御手段52(図示せず)を具備している。53は洗濯槽26に設けた溢水口で、溢水口の先は排水弁よりも下流の排水管49に接続されている。結露排水路48の一部は溢水口53よりも高い位置まで立ち上げられて配設されている。   Reference numeral 47 denotes a washing drainage channel for draining wastewater during washing, and the washing drainage channel 47 has a drain valve 60. Reference numeral 48 denotes a condensation drainage channel through which the condensed water generated by the heat absorber 38 flows when drying. 51 is a drainage pump that sends the condensed water to the condensation drainage channel 48. ing. The tip 50 of the drain pipe 49 is open to the atmosphere outside the machine. Control means 52 (not shown) for controlling the drain valve 60 and the drain pump 51 is provided. 53 is an overflow port provided in the washing tub 26, and the tip of the overflow port is connected to a drain pipe 49 downstream of the drain valve. A part of the condensation drainage channel 48 is arranged to be raised to a position higher than the overflow port 53.
以上のように構成された洗濯乾燥機について、以下、その動作、作用を説明する。洗濯、すすぎ、脱水までの洗濯工程では、水を溜める場合は、排水弁60が閉であり、水供給バルブ(図示せず)から洗濯槽26に水が供給され、図2の水位Dの位置まで所定量の水が溜められる。万が一この水位以上に給水されても洗濯槽26には溢水口53が設けられており、所定量を超えた水は溢れて溢水口53から排水管49に流れて排水される。   The operation and action of the washing / drying machine configured as described above will be described below. In the washing process from washing to rinsing and dehydration, when water is stored, the drain valve 60 is closed and water is supplied from the water supply valve (not shown) to the washing tub 26, and the position of the water level D in FIG. A predetermined amount of water is accumulated. Even if water is supplied above this level, the washing tub 26 is provided with an overflow port 53, and water exceeding a predetermined amount overflows and flows from the overflow port 53 to the drain pipe 49 and is drained.
回転ドラム28がプログラムされた回転数で連続または間欠的に回転すると、洗浄やすすぎが行なわれる。この間、衣類31は回転ドラム28の回転によって持ち上げられ落下する。排水する場合は、排水弁60を開にする。洗濯槽26の水は、洗濯排水路47と排水弁60を通過して排水管49から機外に排水される。   When the rotating drum 28 rotates continuously or intermittently at a programmed number of rotations, cleaning and rinsing are performed. During this time, the clothes 31 are lifted and dropped by the rotation of the rotary drum 28. When draining, the drain valve 60 is opened. The water in the washing tub 26 passes through the washing drain channel 47 and the drain valve 60 and is drained out of the machine from the drain pipe 49.
乾燥工程では、排水弁60を閉として、圧縮機35、送風手段43および回転ドラム28が運転される。送風手段43の運転によって、乾燥用空気が洗濯槽26とダクト44、フレキシブルホース41、風路40、フレキシブルホース42の内部を循環する。衣類31は、あらかじめ設定された回転数で連続または間欠的に行われる回転ドラム28の回転によって撹拌される。   In the drying process, the drain valve 60 is closed, and the compressor 35, the air blowing means 43, and the rotary drum 28 are operated. By the operation of the blowing means 43, the drying air circulates inside the washing tub 26 and the duct 44, the flexible hose 41, the air path 40, and the flexible hose 42. The clothes 31 are agitated by the rotation of the rotating drum 28 continuously or intermittently performed at a preset number of rotations.
圧縮機35の運転によって、管路39内を冷媒が循環して、放熱器36で高温高圧の冷媒の熱を放熱して循環する乾燥用空気を加熱する。加熱された乾燥用空気は図2の矢印Cのように、洗濯槽26内に送り込まれ、回転ドラム28底面部の開口部46を通過して衣類31に当たり、衣類31から水分を奪って、多湿の空気となって回転ドラム28の側壁の孔45を通過して、洗濯槽26の開口部56を通過してダクト44へと送られる。   By the operation of the compressor 35, the refrigerant circulates in the pipe 39, and the heat of the high-temperature and high-pressure refrigerant is radiated by the radiator 36 to heat the circulating drying air. The heated drying air is sent into the washing tub 26 as shown by an arrow C in FIG. 2, passes through the opening 46 in the bottom of the rotating drum 28 and hits the clothing 31, deprives the clothing 31 of moisture, and is humid. The air passes through the hole 45 on the side wall of the rotary drum 28, passes through the opening 56 of the washing tub 26, and is sent to the duct 44.
ダクト44を通過した乾燥用空気は、矢印Bに示すように、フレキシブルホース41を通過して風路40に設けた除湿手段としての吸熱器38で、冷却除湿される。除湿された乾燥用空気は、再び送風手段43によって放熱器36に送られて加熱される。吸熱器38で発生した結露水は、結露非水路48を通過して排水管49から機外に排出される。 The drying air that has passed through the duct 44 passes through the flexible hose 41 and is dehumidified by a heat absorber 38 as a dehumidifying means provided in the air passage 40 as indicated by an arrow B. The dehumidified drying air is sent again to the radiator 36 by the blowing means 43 and heated. Dew condensation water generated in the heat absorber 38 is discharged from the discharge pipe 49 passes through the condensing Non waterway 4 8 outside the apparatus.
結露排水路48の一部を洗濯槽26に設けた溢水口53よりも高位に配設したものであり、洗濯水の排水開始直後の水位による水圧が結露排水路48に加わって結露排水路48内の水位が上昇しても、また、給水弁や水位センサなどの異常による洗濯水の水位上昇が発生しても、溢水口53よりも水位が上昇することがなく、結露排水路48の一部がこの溢水口53よりも高位に配設されているため、これを乗り越えて洗濯水が除湿手段など各手段まで逆流することがない。よって、1つの排水管49で洗濯水も結露水も機外に排水することができる。   A part of the condensation drainage channel 48 is disposed higher than the overflow port 53 provided in the washing tub 26, and the water pressure due to the water level immediately after the start of drainage of the washing water is applied to the condensation drainage channel 48, and the condensation drainage channel 48. Even if the water level in the water rises, or even if the water level of the washing water rises due to an abnormality such as a water supply valve or a water level sensor, the water level does not rise above the overflow port 53, and the condensation drainage channel 48 Since the portion is arranged higher than the overflow port 53, the washing water does not flow back to each means such as the dehumidifying means. Accordingly, both the washing water and the dew condensation water can be drained out of the machine with one drain pipe 49.
なお、本実施例で示す放熱器36や吸熱器38の熱交換器は、プレートフィン付きチューブ型熱交換器を示しているが、特にその形態を限定するものではない。   In addition, although the heat exchanger of the heat radiator 36 and the heat absorber 38 shown in a present Example has shown the tube type heat exchanger with a plate fin, the form is not specifically limited.

FIG. 3 is a side sectional view of the washing / drying machine according to the second embodiment of the present invention. In addition, the same structure as the said Example 1 attaches | subjects the same code | symbol, and abbreviate | omits detailed description.
図3において、結露排水路54の吐水口55を、洗濯槽26に設けた溢水口53よりも高い位置で洗濯槽26に接続したものであり、洗濯水の水位上昇が発生しても、溢水口53よりも水位が上昇することがなく、結露排水路54の吐水口55がこの溢水口53よりも高位に配設されているため、これを乗り越えて洗濯水が除湿手段など各手段まで逆流することがない。よって、1つの排水管49で洗濯水も結露水も機外に排水することができる。   In FIG. 3, the water outlet 55 of the condensation drainage channel 54 is connected to the washing tub 26 at a position higher than the overflow outlet 53 provided in the washing tub 26. Since the water level does not rise above the mouth 53 and the water outlet 55 of the condensation drainage channel 54 is disposed higher than the water overflow port 53, the washing water flows back to each means such as a dehumidifying means over the above. There is nothing to do. Accordingly, both the washing water and the dew condensation water can be drained out of the machine with one drain pipe 49.
また、結露排水経路54の接続を溢水口53近くにすれば、実施例1の結露排水路48よりも結露排水路54の経路長を短くできる。さらに、冷却された結露水を洗濯槽26に流すことによって衣類31を通過後の乾燥用空気と接触するので、吸熱器38で冷却する前に、結露水で乾燥用空気を予め冷却することができる。   If the condensation drainage channel 54 is connected near the overflow port 53, the length of the condensation drainage channel 54 can be made shorter than the condensation drainage channel 48 of the first embodiment. Furthermore, since the cooled dew condensation water is caused to flow into the washing tub 26 and contact with the drying air after passing through the clothing 31, the drying air can be pre-cooled with the dew condensation water before cooling with the heat absorber 38. it can.

FIG. 4 is a side sectional view of the washing / drying machine according to the third embodiment of the present invention. The same components as those in the first and second embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.
図4において、61は結露水を一時溜めるドレイン受けで、排水ポンプ51はドレイン受け61の結露水を結露排水路48へ送る。ドレイン受け61は、前記排水ポンプの作動終了後に前記結露排水路に残った結露水が逆流する水量よりも十分大きい容量を有するものであり、洗濯水の排水開始直後の水位による水圧が結露排水路48に加わって結露排水路48内の水位が上昇しても、また、給水弁や水位センサなどの異常による洗濯水の水位上昇が発生しても、溢水口53よりも水位が上昇することがなく、結露排水路48の一部がこの溢水口53よりも高位に配設されているため、これを乗り越えて洗濯水が除湿手段など各手段まで逆流することがない。   In FIG. 4, 61 is a drain receiver that temporarily stores condensed water, and a drain pump 51 sends the condensed water from the drain receiver 61 to the condensed drainage channel 48. The drain receiver 61 has a capacity that is sufficiently larger than the amount of water in which the condensed water remaining in the condensation drainage channel after the drainage pump has been operated, and the water pressure due to the water level immediately after the start of drainage of the washing water is the condensation drainage channel. Even if the water level in the condensate drainage channel 48 rises in addition to 48, or the wash water level rises due to an abnormality such as a water supply valve or a water level sensor, the water level may rise above the overflow port 53. In addition, since a part of the condensation drainage channel 48 is disposed at a higher position than the overflow port 53, the washing water does not flow back to each means such as the dehumidifying means.
また、ベーンポンプなどはポンプ室が閉じられた構成のため、ポンプ停止時に高位にある配管などの残水が逆流することはないが、遠心ポンプなどはポンプ室が開放されているため、ポンプ停止時に高位にある配管などの残水が逆流することが考えられる。この場合にも、ドレイン受け61の容量が大きいので結露排水路48に残った結露水がドレイン受け61に溜まり、除湿手段など各手段まで逆流することがない。よって、1つの排水管で洗濯水も結露水も機外に排水することができる。   In addition, because vane pumps, etc., have a structure in which the pump chamber is closed, residual water such as high-level piping does not flow back when the pump is stopped, but centrifugal pumps, etc., are open when the pump is stopped. It is conceivable that the residual water from the piping at a higher level will flow backward. Also in this case, since the capacity of the drain receptacle 61 is large, the dew condensation water remaining in the condensation drainage channel 48 does not collect in the drain receptacle 61 and flows back to each means such as the dehumidifying means. Accordingly, both the washing water and the dew condensation water can be drained out of the machine with one drain pipe.

FIG. 5 is a sectional side view of the washing / drying machine of Example 4 of the present invention. In addition, the thing of the same structure as the said Examples 1-3 attaches | subjects the same code | symbol, and abbreviate | omits detailed description.
除湿手段としてのヒートポンプ装置や送風手段43および風路40などは、洗濯槽26に設けた溢水口53よりも高位に配設されている。結露排水路48は排水管49に接続されている。   The heat pump device as the dehumidifying means, the air blowing means 43, the air passage 40, and the like are disposed higher than the overflow port 53 provided in the washing tub 26. The condensation drainage channel 48 is connected to a drainage pipe 49.
以上のような構成によれば、洗濯水の水位上昇が発生しても、溢水口53よりも水位が上昇することがなく、除湿手段などの各手段がこの溢水口53よりも高位に配設されているため、洗濯水が除湿手段まで逆流することがない。よって、1つの排水管49で洗濯水も結露水も機外に排水することができる。   According to the configuration described above, even if the water level of the washing water rises, the water level does not rise above the overflow port 53, and each means such as a dehumidifying means is disposed higher than the overflow port 53. Therefore, the washing water does not flow back to the dehumidifying means. Accordingly, both the washing water and the dew condensation water can be drained out of the machine with one drain pipe 49.
なお、結露排水路48は排水管49に接続する以外に、図6に示すように洗濯槽26に接続してもよく、結露水が自然落下で流れる方向に水路を形成すればよく、接続先を特に限定するものではない。   The condensation drainage channel 48 may be connected to the washing tub 26 as shown in FIG. 6 in addition to being connected to the drainage pipe 49, and it is only necessary to form a waterway in the direction in which the condensation water flows by natural fall. Is not particularly limited.
また、本発明の実施例のヒートポンプ装置の熱源に代えて、ヒータを熱源にする洗濯乾燥機でも同様である。図7はヒータ式の洗濯乾燥機を背面から見た一部切欠斜視図である。図7において、57は乾燥用空気を加熱するヒータ、58は衣類31から水分を奪って多湿となった乾燥用空気を、より低い機外の空気で冷却除湿するための熱交換器である。熱交換器58は直交プレートフィン型熱交換器であり、乾燥用空気に直交するように機外空気の空気が空冷用送風手段59によって送風される。矢印Eは空冷用送風手段59によって送風される冷却用の機外空気の流れを示す。   The same applies to a washer-dryer using a heater as a heat source instead of the heat source of the heat pump apparatus according to the embodiment of the present invention. FIG. 7 is a partially cutaway perspective view of a heater-type washing / drying machine as viewed from the back. In FIG. 7, 57 is a heater that heats the drying air, and 58 is a heat exchanger that cools and dehumidifies the drying air that has become wet due to moisture from the garment 31 with lower outside air. The heat exchanger 58 is an orthogonal plate fin type heat exchanger, and the air of the outside air is blown by the air-cooling blowing means 59 so as to be orthogonal to the drying air. An arrow E indicates the flow of the cooling external air blown by the air cooling blowing means 59.
上記構成によれば、衣類通過後の乾燥用空気を空気で冷却除湿するものであり、熱交換器58で発生した結露水は、結露排水路48と排水弁60を通過して排水管49から機外に排出される。   According to the above configuration, the drying air after passing through the clothes is cooled and dehumidified with air, and the condensed water generated in the heat exchanger 58 passes through the condensed drainage channel 48 and the drainage valve 60 from the drainage pipe 49. It is discharged outside the machine.
なお、熱交換器58はプレーフィン付きチューブ型熱交換器でも同様であり、特に熱交
換器の形態を限定するものでもない。
The heat exchanger 58 is the same as a tube-type heat exchanger with a prefin, and the form of the heat exchanger is not particularly limited.
