Description

本発明は、洗濯乾燥機、乾燥制御方法および洗濯方法に関する。   The present invention relates to a washing / drying machine, a drying control method, and a washing method.

従来から、一般家庭で行なわれる衣類の洗濯と乾燥とを同一槽で行なう洗濯乾燥機として、省エネルギー化の観点から、ヒートポンプ装置を用いた洗濯乾燥機が注目されている。   2. Description of the Related Art Conventionally, a washing / drying machine using a heat pump device has attracted attention as a washing / drying machine that performs washing and drying of clothes performed in a general household in the same tank from the viewpoint of energy saving.

図７に、従来の特許文献１に記載の洗濯乾燥機としても用いることができる衣類乾燥装置の主要な構成を示す。図７に示す衣類乾燥装置は、圧縮機１２０、放熱器１２１、熱バランス手段１２９、絞り手段１２２および吸熱器１２３を順に接続して再び圧縮機１２０に冷媒１３２が循環するように管路１２４で連結したヒートポンプ装置がを備えている。ここで、ヒートポンプ装置は、乾燥庫１２７に収容された衣類１１９を乾燥させる乾燥用空気１２６を流すための風路１２５に取り付けられている。   FIG. 7 shows a main configuration of a clothes drying apparatus that can also be used as a washing and drying machine described in Patent Document 1. The clothes drying apparatus shown in FIG. 7 is connected to the compressor 120, the radiator 121, the heat balance means 129, the throttle means 122, and the heat absorber 123 in this order, so that the refrigerant 132 circulates again through the compressor 120. A coupled heat pump device is provided. Here, the heat pump device is attached to the air passage 125 for flowing the drying air 126 for drying the clothes 119 housed in the drying cabinet 127.

図７に示す衣類乾燥装置を用いて乾燥庫１２７に収容された衣類１１９を乾燥させる際には、まず、送風機１２８と圧縮機１２０とを作動させる。送風機１２８を作動させることによって乾燥用空気１２６は風路１２５を循環し始めるが、乾燥用空気１２６が放熱器１２１を通過する際に放熱器１２１からの放熱により加熱されて乾燥庫１２７内に送風される。   When drying the clothes 119 stored in the drying cabinet 127 using the clothes drying apparatus shown in FIG. 7, first, the blower 128 and the compressor 120 are operated. By operating the blower 128, the drying air 126 starts to circulate through the air passage 125. However, when the drying air 126 passes through the radiator 121, the drying air 126 is heated by heat radiation from the radiator 121 and blown into the drying chamber 127. Is done.

乾燥庫１２７内で衣類１１９と接触した乾燥用空気１２６は、衣類１１９から水分を奪って衣類１１９を乾燥して、乾燥庫１２７から排出される。乾燥用空気１２６は、衣類１１９の水分に蒸発のための熱量として顕熱を与えるため温度が低下するが、衣類１１９から放出されたほぼ同等の潜熱を有する水蒸気を含んで高湿の空気となる。   The drying air 126 that has come into contact with the clothing 119 in the drying cabinet 127 deprives the clothing 119 of moisture and dries the clothing 119 and is discharged from the drying cabinet 127. The drying air 126 is subjected to sensible heat as the amount of heat for evaporation to the moisture of the garment 119, but the temperature is lowered. However, the drying air 126 contains steam having substantially the same latent heat released from the garment 119 and becomes high-humidity air. .

乾燥庫１２７から流出した高湿の乾燥用空気１２６は、吸熱器１２３を通過する際に冷却されて潜熱を奪われ、結露が生じることにより除湿される。除湿されて絶対湿度が低下した乾燥用空気１２６は、再び放熱器１２１で加熱される。   The high-humidity drying air 126 that has flowed out of the drying cabinet 127 is cooled when passing through the heat absorber 123, deprived of latent heat, and dehumidified by causing condensation. The drying air 126 that has been dehumidified and whose absolute humidity has been reduced is heated again by the radiator 121.

一方、ヒートポンプ装置では、圧縮機１２０で圧縮された高温高圧の冷媒１３２の熱が放熱器１２１で放熱される。さらに、放熱器１２１で冷媒１３２から乾燥用空気１２６に熱を与えた後の管路１２４において、熱バランス手段１２９の熱交換器１３０および冷却用送風手段１３１が冷媒１３２と外部空気との熱交換を行ない、冷媒１３２の熱の一部が外部に放出される。そして、熱バランス手段１２９を通過した高圧の冷媒１３２が、絞り手段１２２で減圧されて低圧低温となり、吸熱器１２３で乾燥用空気１２６から熱を奪い再び圧縮機１２０に戻る。   On the other hand, in the heat pump device, the heat of the high-temperature and high-pressure refrigerant 132 compressed by the compressor 120 is radiated by the radiator 121. Further, in the pipe 124 after heat is supplied from the refrigerant 132 to the drying air 126 by the radiator 121, the heat exchanger 130 of the heat balance means 129 and the cooling air blowing means 131 exchange heat between the refrigerant 132 and external air. And part of the heat of the refrigerant 132 is released to the outside. Then, the high-pressure refrigerant 132 that has passed through the heat balance means 129 is depressurized by the throttle means 122 to become low pressure and low temperature, takes heat from the drying air 126 by the heat absorber 123, and returns to the compressor 120 again.

図７に示す衣類乾燥装置においては、冷媒１３２が吸熱器１２３で乾燥用空気１２６から奪った熱量に圧縮機１２０の入力によって冷媒１３２に加えられた熱量を加えた熱量が放熱器１２１から放出されるが、熱バランス手段１２９において圧縮機１２０の入力に相当する熱量が予め外部に放出される。   In the clothes drying apparatus shown in FIG. 7, the heat quantity obtained by adding the amount of heat applied to the refrigerant 132 by the input of the compressor 120 to the quantity of heat taken by the refrigerant 132 from the drying air 126 by the heat absorber 123 is released from the radiator 121. However, the heat balance means 129 releases the amount of heat corresponding to the input of the compressor 120 to the outside in advance.

そのため、図７に示す衣類乾燥装置においては、放熱器１２１から熱を得て高温となった乾燥用空気１２６の一部を衣類１１９に接触させる前に外部に排気する必要がないことから、省エネルギー化のより高い乾燥ができるとされている。   Therefore, in the clothes drying apparatus shown in FIG. 7, it is not necessary to exhaust a part of the drying air 126 that has obtained heat from the radiator 121 and has reached a high temperature before contacting the clothes 119. It is said that it can be dried at a higher rate.

しかしながら、上記の特許文献１に記載の衣類乾燥装置においても、熱バランス手段１２９から熱量の一部を外部に放出しているため、熱を十分に有効利用できているとは言えない。   However, even in the clothes drying apparatus described in the above-mentioned Patent Document 1, it cannot be said that the heat can be sufficiently effectively utilized because a part of the heat amount is released from the heat balance means 129 to the outside.

＜実施の形態１＞
図１に、本発明の洗濯乾燥機の一例である実施の形態１の洗濯乾燥機の模式的な構成図を示す。ここで、実施の形態１の洗濯乾燥機は、ヒートポンプユニット１０と、ヒートポンプユニット１０が取り付けられた乾燥用気体流路３０と、乾燥用気体流路３０に連結された洗濯乾燥室２０とを備えている。 <Embodiment 1>
In FIG. 1, the typical block diagram of the washing-drying machine of Embodiment 1 which is an example of the washing-drying machine of this invention is shown. Here, the washing / drying machine of Embodiment 1 includes a heat pump unit 10, a drying gas flow path 30 to which the heat pump unit 10 is attached, and a washing / drying chamber 20 connected to the drying gas flow path 30. ing.

ヒートポンプユニット１０は、圧縮機１１と、凝縮器１２と、絞り装置１３と、蒸発器１４とを有しており、圧縮機１１、凝縮器１２、絞り装置１３および蒸発器１４の順に冷媒１６が循環するように、圧縮機１１と凝縮器１２、凝縮器１２と絞り装置１３、絞り装置１３と蒸発器１４、蒸発器１４と圧縮機１１がそれぞれ冷媒流路１５によって連結されている。   The heat pump unit 10 includes a compressor 11, a condenser 12, a throttling device 13, and an evaporator 14. The refrigerant 16 is in the order of the compressor 11, the condenser 12, the throttling device 13, and the evaporator 14. The compressor 11 and the condenser 12, the condenser 12 and the expansion device 13, the expansion device 13 and the evaporator 14, and the evaporator 14 and the compressor 11 are connected by a refrigerant flow path 15 so as to circulate.

ヒートポンプユニット１０の凝縮器１２および蒸発器１４がそれぞれ乾燥用気体流路３０の本流路３１に取り付けられている。乾燥用気体流路３０の本流路３１はその中を流れるたとえば空気などの乾燥用気体５０が、凝縮器１２、洗濯乾燥室２０および蒸発器１４の順に循環するように環状に形成されている。   The condenser 12 and the evaporator 14 of the heat pump unit 10 are respectively attached to the main flow path 31 of the drying gas flow path 30. The main flow path 31 of the drying gas flow path 30 is formed in an annular shape so that a drying gas 50 such as air flowing through the flow path 31 circulates in the order of the condenser 12, the washing / drying chamber 20, and the evaporator 14.

また、乾燥用気体流路３０は、本流路３１とともに、凝縮器１２から洗濯乾燥室２０までの間の本流路３１の部分に本流路３１から一旦分岐した後に再度本流路３１に合流するバイパス流路３２を備えている。   In addition, the drying gas flow channel 30, together with the main flow channel 31, bypasses the main flow channel 31 once from the main flow channel 31 to the portion of the main flow channel 31 between the condenser 12 and the washing / drying chamber 20 and then joins the main flow channel 31 again. A path 32 is provided.

実施の形態１の洗濯乾燥機は、さらに、バイパス流路３２に設けられた流入量調節ユニット４１と、洗濯乾燥室２０内に設けられた温度測定ユニット６０とにそれぞれ接続された制御ユニット７０を備えている。   The washing / drying machine according to the first embodiment further includes a control unit 70 connected to the inflow amount adjusting unit 41 provided in the bypass flow path 32 and the temperature measurement unit 60 provided in the washing / drying chamber 20. I have.

以下、図１に示す実施の形態１の洗濯乾燥機を用いた洗濯乾燥方法の一例について説明する。まず、洗濯乾燥室２０内に洗濯乾燥の対象物となる衣類８０を設置する。   Hereinafter, an example of a washing and drying method using the washing and drying machine of the first embodiment shown in FIG. 1 will be described. First, clothes 80 that are objects of washing and drying are installed in the washing and drying chamber 20.

次に、乾燥用気体流路３０の本流路３１に設けられた図示しない送風機を作動させるとともに、ヒートポンプユニット１０の圧縮機１１を作動させる。これにより、乾燥用気体流路３０の本流路３１においては乾燥用気体５０の循環が開始するとともに、ヒートポンプユニット１０においては以下の動作が行なわれる。なお、乾燥用気体流路３０の本流路３１における送風機の設置箇所は、乾燥用気体流路３０の本流路３１において乾燥用気体５０を循環させることができるものであれば特に限定されない。   Next, a blower (not shown) provided in the main flow path 31 of the drying gas flow path 30 is operated, and the compressor 11 of the heat pump unit 10 is operated. Thereby, the circulation of the drying gas 50 starts in the main flow path 31 of the drying gas flow path 30, and the following operation is performed in the heat pump unit 10. The installation location of the blower in the main flow path 31 of the drying gas flow path 30 is not particularly limited as long as the drying gas 50 can be circulated in the main flow path 31 of the drying gas flow path 30.

ヒートポンプユニット１０の圧縮機１１で圧縮されることにより高温高圧となった冷媒１６は冷媒流路１５を通って凝縮器１２に流れ込み、凝縮器１２で凝縮されることにより熱を乾燥用気体流路３０の本流路３１を流れる乾燥用気体５０に放出する。   The refrigerant 16, which has become high temperature and pressure by being compressed by the compressor 11 of the heat pump unit 10, flows into the condenser 12 through the refrigerant flow path 15, and is condensed by the condenser 12, so that heat is transferred to the drying gas flow path. It is discharged into the drying gas 50 flowing through the 30 main flow paths 31.

そして、凝縮器１２で熱を放出した後の高圧の冷媒１６は、絞り装置１３で減圧されて低温低圧の冷媒１６となり、蒸発器１４で本流路３１を流れる乾燥用気体５０から熱を奪って圧縮機１１に戻る。   The high-pressure refrigerant 16 after releasing the heat in the condenser 12 is decompressed by the expansion device 13 to become a low-temperature and low-pressure refrigerant 16, and the evaporator 14 takes heat from the drying gas 50 flowing through the main flow path 31. Return to the compressor 11.

また、乾燥用気体流路３０の本流路３１を流れる乾燥用気体５０は、凝縮器１２から放出された熱により低湿高温の気体となって洗濯乾燥室２０内に流れ込み、洗濯乾燥室２０内の衣類８０と接触して衣類８０から水分を奪って衣類８０を乾燥させる。   Further, the drying gas 50 flowing through the main flow path 31 of the drying gas flow path 30 flows into the washing / drying chamber 20 as a low-humidity and high-temperature gas by the heat released from the condenser 12. The clothes 80 are dried by contacting the clothes 80 and removing moisture from the clothes 80.

乾燥用気体５０は、衣類８０から水分を蒸発させるための熱量として顕熱を水分に与えることから温度が低下するが、衣類８０から放出されたほぼ同等の潜熱を有する水蒸気を含む高湿高温の気体となる。   The temperature of the drying gas 50 is reduced because the sensible heat is given to the moisture as the amount of heat for evaporating the moisture from the garment 80, but the drying gas 50 has a high humidity and high temperature including water vapor having substantially the same latent heat released from the garment 80. It becomes gas.

そして、高湿高温の乾燥用気体５０は洗濯乾燥室２０から蒸発器１４に流れ込み、蒸発器１４で冷媒１６に熱を放出して冷却され、潜熱を奪われて結露し、除湿される。その後、低温となって除湿された低湿低温の乾燥用気体５０は、凝縮器１２で冷媒１６から放出された熱によって加熱されて低湿高温の気体となって、衣類８０を乾燥するために再度洗濯乾燥室２０内に流れ込む。   Then, the high-humidity and high-temperature drying gas 50 flows from the washing / drying chamber 20 into the evaporator 14, where the evaporator 14 releases heat to the refrigerant 16, cools, deprives the latent heat, condenses, and dehumidifies. Thereafter, the low-humidity low-temperature drying gas 50 dehumidified at low temperature is heated by the heat released from the refrigerant 16 in the condenser 12 to become a low-humidity high-temperature gas, and is washed again to dry the clothing 80. It flows into the drying chamber 20.

ここで、実施の形態１の洗濯乾燥機においては、凝縮器１２で加熱されて低湿高温の気体となった本流路３１を流れる乾燥用気体５０の一部がバイパス流路３２を流れた後に本流路３１を流れる乾燥用気体５０と合流して洗濯乾燥室２０内に流れ込むことを特徴の１つとしている。   Here, in the washing / drying machine of the first embodiment, the main stream after a part of the drying gas 50 flowing through the main flow path 31 heated to the low-humidity high-temperature gas by the condenser 12 flows through the bypass flow path 32. One of the features is that the drying gas 50 that flows through the passage 31 joins and flows into the washing / drying chamber 20.

すなわち、図２の模式的拡大構成図に示すように、本流路３１を流れる低湿高温の乾燥用気体５０ａの一部がバイパス流路３２に流れ込み、バイパス流路３２に設けられた蓄熱ユニット４２に熱を放出して低湿低温の乾燥用気体５０ｂとなる。そして、低湿低温の乾燥用気体５０ｂは再度本流路３１に流れ込み、本流路３１を流れる低湿高温の乾燥用気体５０ａと合流して、乾燥用気体５０ａよりも温度が低く、乾燥用気体５０ｂよりも温度が高い低湿中温の乾燥用気体５０ｃとなって洗濯乾燥室２０内に流れ込む。   That is, as shown in the schematic enlarged configuration diagram of FIG. 2, a part of the low-humidity and high-temperature drying gas 50 a flowing through the main flow channel 31 flows into the bypass flow channel 32, and enters the heat storage unit 42 provided in the bypass flow channel 32. The heat is released to become a low-humidity low-temperature drying gas 50b. Then, the low-humidity and low-temperature drying gas 50b flows again into the main flow path 31 and merges with the low-humidity and high-temperature drying gas 50a flowing through the main flow path 31 so that the temperature is lower than the drying gas 50a and is lower than the drying gas 50b. It becomes a low-humidity / medium-temperature drying gas 50 c having a high temperature and flows into the washing / drying chamber 20.

一方、乾燥用気体５０ａから熱を奪った蓄熱ユニット４２はその熱を蓄えておき、たとえば図３の模式的拡大構成図に示すように、洗濯乾燥室２０内の衣類８０を洗濯するために、たとえば水道などの液体供給ユニット９０から液体用供給路９１に放出されたたとえば冷水などの液体９２ａに熱を与えて温度を上昇させ、たとえば温水などの中温の液体９２ｂとすることができる。   On the other hand, the heat storage unit 42 deprived of heat from the drying gas 50a stores the heat. For example, as shown in the schematic enlarged configuration diagram of FIG. 3, in order to wash the clothes 80 in the washing / drying chamber 20, For example, heat can be applied to the liquid 92a such as cold water discharged from the liquid supply unit 90 such as water supply to the liquid supply path 91 to raise the temperature, and the medium 92b such as hot water can be obtained.

このように、実施の形態１の洗濯乾燥機においては、従来の特許文献１に記載の衣類乾燥装置のように熱バランス手段において圧縮機の入力に相当する熱量を外部に捨てることなく蓄熱ユニット４２に蓄えることができ、蓄熱ユニット４２に蓄えられた熱を洗濯乾燥室２０内に供給される冷水を温水にするのに有効利用して衣類８０の洗濯を行なうことができる。   Thus, in the washing and drying machine of the first embodiment, unlike the conventional clothes drying apparatus described in Patent Document 1, the heat storage unit 42 does not throw away the amount of heat corresponding to the input of the compressor in the heat balance means. The clothes 80 can be washed by effectively using the heat stored in the heat storage unit 42 to make the cold water supplied into the washing / drying chamber 20 warm.

したがって、実施の形態１の洗濯乾燥機においては、上記の熱の有効利用の結果として、たとえば衣類８０の洗濯時に衣類８０とともに洗濯乾燥室２０内に投入される洗剤等を中温の液体９２ｂで溶けやすくすることができるため、衣類８０の洗濯効果を高めることができる。   Therefore, in the washing / drying machine according to the first embodiment, as a result of the effective use of the heat, for example, a detergent or the like put into the washing / drying chamber 20 together with the clothing 80 when washing the clothing 80 is dissolved in the medium-temperature liquid 92b. Since it can make it easy, the washing effect of clothing 80 can be heightened.

図７に示す従来の特許文献１に記載の衣類乾燥装置においては、圧縮機１２０の入力に相当する熱量を熱バランス手段１２９で予め外部に放出し、放熱器１２１で冷媒１３２から放出される熱量と、吸熱器１２３で乾燥用空気１２６から冷媒１３２に加えられる熱量とを等しくすることによって、ヒートポンプ装置の冷凍サイクルを安定して継続的に運転している。   In the conventional clothes drying apparatus described in Patent Document 1 shown in FIG. 7, the amount of heat corresponding to the input of the compressor 120 is previously released to the outside by the heat balance means 129 and the amount of heat released from the refrigerant 132 by the radiator 121. In addition, by making the amount of heat applied to the refrigerant 132 from the drying air 126 by the heat absorber 123 equal, the refrigeration cycle of the heat pump device is stably operated continuously.

これは、ヒートポンプ装置の冷凍サイクルのサイクル数が増えるにつれて、圧縮機１２０から冷媒１３２に入力される熱量が増加していくため、放熱器１２１で冷媒１３２から放出される熱量が大きくなって冷媒１３２の温度および圧力が上昇していき、ヒートポンプ装置の冷凍サイクルを安定して継続的に運転させることができなくなるためである。   This is because the amount of heat input from the compressor 120 to the refrigerant 132 increases as the number of cycles of the refrigeration cycle of the heat pump device increases, so that the amount of heat released from the refrigerant 132 by the radiator 121 increases. This is because the temperature and pressure of the heat pump rise and the refrigeration cycle of the heat pump device cannot be operated stably and continuously.

一方、実施の形態１の洗濯乾燥機は、従来の特許文献１に記載の衣類乾燥装置で外部に放出されていた熱量に相当する熱量を蓄熱ユニット４２に蓄えて、衣類８０の洗濯時に有効利用することができるため、従来よりも熱を有効利用することが可能となる。   On the other hand, the washing / drying machine according to the first embodiment stores heat in the heat storage unit 42 corresponding to the amount of heat released to the outside by the clothes drying apparatus described in Patent Document 1 so that it can be effectively used when washing the clothes 80. Therefore, heat can be used more effectively than in the past.

さらに、実施の形態１の洗濯乾燥機においては、制御ユニット７０によって、温度測定ユニット６０で測定された洗濯乾燥室２０内の温度に基づいて流入量調節ユニット４１を制御して蓄熱ユニット４２に流入する乾燥用気体５０の流入量を調節できることも特徴としている。   Furthermore, in the washer / dryer of the first embodiment, the control unit 70 controls the inflow amount adjusting unit 41 based on the temperature in the washing / drying chamber 20 measured by the temperature measuring unit 60 and flows into the heat storage unit 42. Another feature is that the inflow amount of the drying gas 50 can be adjusted.

図４に、実施の形態１の洗濯乾燥機の制御ユニット７０による乾燥制御方法の一例のフローチャートを示す。以下、図４を参照して、実施の形態１の洗濯乾燥機の制御ユニット７０による乾燥制御方法の一例について説明する。   FIG. 4 shows a flowchart of an example of a drying control method by the control unit 70 of the washing and drying machine of the first embodiment. Hereinafter, an example of a drying control method performed by the control unit 70 of the washing / drying machine according to the first embodiment will be described with reference to FIG.

まず、ステップＳ１に示すように、温度測定ユニット６０によって洗濯乾燥室２０内の温度の測定を開始する。次に、ステップＳ２に示すように、図示しない送風機および圧縮機１１をそれぞれ作動させる。   First, as shown in step S1, the temperature measurement unit 60 starts measuring the temperature in the washing / drying chamber 20. Next, as shown in step S2, the blower and the compressor 11 (not shown) are operated.

次に、ステップＳ３に示すように、制御ユニット７０は、温度測定ユニット６０から送信されてくる洗濯乾燥室２０内の温度情報に基づいて、洗濯乾燥室２０内の温度が所定の温度（たとえば６５℃）以上かどうかを判断する。ここで、所定の温度は特に限定されないが、たとえばヒートポンプユニット１０における冷凍サイクルを安定して継続的に運転させることができる温度に設定することが好ましい。   Next, as shown in step S3, the control unit 70 sets the temperature in the laundry drying chamber 20 to a predetermined temperature (for example, 65) based on the temperature information in the laundry drying chamber 20 transmitted from the temperature measurement unit 60. ° C) or higher. Here, the predetermined temperature is not particularly limited, but is preferably set to a temperature at which the refrigeration cycle in the heat pump unit 10 can be operated stably and continuously, for example.

そして、ステップＳ３において、制御ユニット７０が、洗濯乾燥室２０内の温度が所定の温度以上でないと判断した場合には、制御ユニット７０は、流入量調節ユニット４１の電動弁の開閉は行なわずに、再度、洗濯乾燥室２０内の温度が所定の温度以上かどうかを判断する。   In step S3, when the control unit 70 determines that the temperature in the washing / drying chamber 20 is not equal to or higher than the predetermined temperature, the control unit 70 does not open / close the electric valve of the inflow amount adjusting unit 41. Then, it is determined again whether the temperature in the washing / drying chamber 20 is equal to or higher than a predetermined temperature.

また、ステップＳ３において、制御ユニット７０が洗濯乾燥室２０内の温度が所定の温度以上であると判断した場合には、ステップＳ４に示すように、流入量調節ユニット４１の電動弁を開いて、蓄熱ユニット４２に流れ込む乾燥用気体５０ａの流入量を増加させる。これにより、バイパス流路３２から本流路３１に合流する乾燥用気体５０ｂの合流量を多くすることができることから、洗濯乾燥室２０内に流入する乾燥用気体５０ｃの温度を低くして、洗濯乾燥室２０内の温度を低くすることができる。   In step S3, when the control unit 70 determines that the temperature in the washing / drying chamber 20 is equal to or higher than the predetermined temperature, as shown in step S4, the electric valve of the inflow rate adjusting unit 41 is opened, The inflow amount of the drying gas 50a flowing into the heat storage unit 42 is increased. As a result, the combined flow rate of the drying gas 50b that merges from the bypass flow channel 32 into the main flow channel 31 can be increased, so that the temperature of the drying gas 50c flowing into the washing / drying chamber 20 can be lowered and the laundry drying performed. The temperature in the chamber 20 can be lowered.

次に、ステップＳ５に示すように、制御ユニット７０は、温度測定ユニット６０から送信されてくる洗濯乾燥室２０内の温度情報に基づいて、洗濯乾燥室２０内の温度が所定の温度未満かどうかを判断する。   Next, as shown in step S <b> 5, the control unit 70 determines whether the temperature in the laundry drying chamber 20 is lower than a predetermined temperature based on the temperature information in the laundry drying chamber 20 transmitted from the temperature measurement unit 60. Judging.

そして、ステップＳ５において、制御ユニット７０が、洗濯乾燥室２０内の温度が所定の温度未満でないと判断した場合には、制御ユニット７０は、流入量調節ユニット４１の電動弁の開閉は行なわずに、再度、洗濯乾燥室２０内の温度が所定の温度未満かどうかを判断する。   In step S5, when the control unit 70 determines that the temperature in the washing / drying chamber 20 is not lower than the predetermined temperature, the control unit 70 does not open / close the electric valve of the inflow amount adjusting unit 41. Then, it is determined again whether the temperature in the washing / drying chamber 20 is lower than a predetermined temperature.

また、ステップＳ５において、制御ユニット７０が、洗濯乾燥室２０内の温度が所定の温度未満であると判断した場合には、ステップＳ６に示すように、制御ユニット７０は、流入量調節ユニット４１の電動弁を閉じて、蓄熱ユニット４２に流れ込む乾燥用気体５０ａの流入量を減少させる。これにより、バイパス流路３２から本流路３１に合流する乾燥用気体５０ｂの合流量を少なくすることができることから、洗濯乾燥室２０内に流入する乾燥用気体５０ｃの温度を高くして、洗濯乾燥室２０内の温度を高くすることができる。   Further, when the control unit 70 determines in step S5 that the temperature in the washing / drying chamber 20 is lower than the predetermined temperature, the control unit 70 controls the inflow rate adjustment unit 41 as shown in step S6. The motor-operated valve is closed to reduce the inflow amount of the drying gas 50a flowing into the heat storage unit 42. As a result, the combined flow rate of the drying gas 50b merging from the bypass flow channel 32 to the main flow channel 31 can be reduced. Therefore, the temperature of the drying gas 50c flowing into the washing / drying chamber 20 is increased, and the laundry drying is performed. The temperature in the chamber 20 can be increased.

ステップＳ６に示すように流入量調節ユニット４１の電動弁を閉じた後には、制御ユニット７０が洗濯乾燥室２０内の温度が所定の温度以上かどうかを判断するステップＳ３に戻り、上述したステップＳ３〜Ｓ６が引き続き繰り返して行なわれる。   After closing the motor-operated valve of the inflow rate adjusting unit 41 as shown in step S6, the control unit 70 returns to step S3 in which it is determined whether the temperature in the washing / drying chamber 20 is equal to or higher than a predetermined temperature, and the above-described step S3. ˜S6 is continuously repeated.

このように、実施の形態１の洗濯乾燥機においては、ヒートポンプユニット１０の運転時間の増加に伴い過剰となる熱量を蓄熱ユニット４２に蓄えながら、制御ユニット７０による流入量調節ユニット４１の制御によって洗濯乾燥室２０内の温度をほぼ一定に保って洗濯乾燥室２０内の衣類８０の乾燥を行なうことができ、それに伴い蒸発器１４に流れ込む乾燥用気体５０の温度の変動も抑えることができる。   As described above, in the washer / dryer of the first embodiment, washing is performed under the control of the inflow amount adjusting unit 41 by the control unit 70 while storing the excess heat amount in the heat storage unit 42 as the operation time of the heat pump unit 10 increases. The clothes 80 in the washing / drying chamber 20 can be dried while keeping the temperature in the drying chamber 20 substantially constant, and accordingly, fluctuations in the temperature of the drying gas 50 flowing into the evaporator 14 can be suppressed.

したがって、実施の形態１の洗濯乾燥機においては、ヒートポンプユニット１０における冷凍サイクルを安定して継続的に運転させながら洗濯乾燥室２０内の衣類８０の洗濯乾燥を行なうことができる。   Therefore, in the laundry dryer of the first embodiment, the clothes 80 in the laundry drying chamber 20 can be washed and dried while the refrigeration cycle in the heat pump unit 10 is stably and continuously operated.

以上のように、実施の形態１の洗濯乾燥機においては、従来よりも熱を有効利用することが可能な洗濯乾燥機、乾燥制御方法および洗濯方法を提供することができる。   As described above, in the washer / dryer of the first embodiment, a washer / dryer, a drying control method, and a washing method capable of more effectively using heat than before can be provided.

＜実施の形態２＞
実施の形態２の洗濯乾燥機は、乾燥用気体流路が複数のバイパス流路を備えている点に特徴がある。図５に、実施の形態２の洗濯乾燥機のバイパス流路近傍の模式的な拡大構成図を示す。 <Embodiment 2>
The washing / drying machine of the second embodiment is characterized in that the drying gas flow path includes a plurality of bypass flow paths. In FIG. 5, the typical enlarged block diagram of the bypass flow path vicinity of the washing / drying machine of Embodiment 2 is shown.

すなわち、図５に示すように、実施の形態２の洗濯乾燥機においては、本流路３１からまず第１のバイパス流路３２ａが分岐し、その後、第２のバイパス流路３２ｂが分岐しており、第１のバイパス流路３２ａおよび第２のバイパス流路３２ｂは本流路３１の同一箇所で合流している。   That is, as shown in FIG. 5, in the washer / dryer of the second embodiment, the first bypass passage 32a is first branched from the main passage 31 and then the second bypass passage 32b is branched. The first bypass channel 32a and the second bypass channel 32b merge at the same location of the main channel 31.

第１のバイパス流路３２ａには、第１の流入量調節ユニット４１ａと、第１の蓄熱ユニット４２ａとが設けられており、第１の流入量調節ユニット４１ａは第１の蓄熱ユニット４２ａの上流側に設置されている。   The first bypass flow path 32a is provided with a first inflow amount adjustment unit 41a and a first heat storage unit 42a. The first inflow amount adjustment unit 41a is upstream of the first heat storage unit 42a. It is installed on the side.

第２のバイパス流路３２ｂには、第２の流入量調節ユニット４１ｂと、第２の蓄熱ユニット４２ｂとが設けられており、第２の流入量調節ユニット４１ｂは第１の蓄熱ユニット４２ｂの上流側に設置されている。   The second bypass flow path 32b is provided with a second inflow amount adjustment unit 41b and a second heat storage unit 42b, and the second inflow amount adjustment unit 41b is located upstream of the first heat storage unit 42b. It is installed on the side.

さらに、制御ユニット７０は、第１のバイパス流路３２ａの第１の流入量調節ユニット４１ａ、第２のバイパス流路３２ｂの第２の流入量調節ユニット４１ｂ、および洗濯乾燥室２０内の温度測定ユニット６０にそれぞれ接続されている。そして、制御ユニット７０は、温度測定ユニット６０から送信されてくる洗濯乾燥室２０内の温度情報に基づいて、第１の流入量調節ユニット４１ａおよび第２の流入量調節ユニット４１ｂをそれぞれ独立に制御することができ、第１の蓄熱ユニット４２ａおよび第２の蓄熱ユニット４２ｂに流入する乾燥用気体５０ａの流入量をそれぞれ調節することができる。   Further, the control unit 70 measures the temperature in the first inflow rate adjusting unit 41a of the first bypass channel 32a, the second inflow rate adjusting unit 41b of the second bypass channel 32b, and the washing / drying chamber 20. Each unit 60 is connected. Then, the control unit 70 independently controls the first inflow rate adjustment unit 41a and the second inflow rate adjustment unit 41b based on the temperature information in the washing / drying chamber 20 transmitted from the temperature measurement unit 60. The inflow amount of the drying gas 50a flowing into the first heat storage unit 42a and the second heat storage unit 42b can be adjusted.

そして、第１の蓄熱ユニット４２ａに流入した低湿高温の乾燥用気体５０ａは、第１の蓄熱ユニット４２ａに熱を放出して低湿低温の乾燥用気体５０ｂとなる。また、第２の蓄熱ユニット４２ｂに流入した乾燥用気体５０ａは、第２の蓄熱ユニット４２ｂに熱を放出して低湿低温の乾燥用気体５０ｂとなる。一方、第１の蓄熱ユニット４２ａおよび第２の蓄熱ユニット４２ｂは、それぞれ、低湿高温の乾燥用気体５０ａから放出された熱を蓄える。   Then, the low-humidity and high-temperature drying gas 50a that has flowed into the first heat storage unit 42a releases heat to the first heat storage unit 42a to become a low-humidity and low-temperature drying gas 50b. Also, the drying gas 50a that has flowed into the second heat storage unit 42b releases heat to the second heat storage unit 42b to become a low humidity, low temperature drying gas 50b. On the other hand, the first heat storage unit 42a and the second heat storage unit 42b each store heat released from the low humidity and high temperature drying gas 50a.

そして、低湿低温の乾燥用気体５０ｂは、第１のバイパス流路３２ａおよび第２のバイパス流路３２ｂからそれぞれ再度本流路３１に流れ込み、本流路３１を流れる低湿高温の乾燥用気体５０ａと合流して、乾燥用気体５０ａよりも温度が低く、乾燥用気体５０ｂよりも温度が高い低湿中温の乾燥用気体５０ｃとなって洗濯乾燥室２０内に流れ込む。   The low-humidity and low-temperature drying gas 50b flows into the main channel 31 again from the first bypass channel 32a and the second bypass channel 32b, and merges with the low-humidity and high-temperature drying gas 50a flowing through the main channel 31. Thus, the temperature becomes lower than that of the drying gas 50a, and the temperature of the drying gas 50b is higher than that of the drying gas 50b.

このように、実施の形態２の洗濯乾燥機においても、ヒートポンプユニット１０の運転時間の増加に伴い過剰となる熱量を蓄熱ユニット４２に蓄えながら、制御ユニット７０による流入量調節ユニット４１の制御によって洗濯乾燥室２０内の温度をほぼ一定に保って洗濯乾燥室２０内の衣類８０の乾燥を行なうことができ、それに伴い蒸発器１４に流れ込む乾燥用気体５０の温度の変動も抑えることができる。   As described above, also in the washer / dryer according to the second embodiment, washing is performed by controlling the inflow amount adjusting unit 41 by the control unit 70 while accumulating excess heat in the heat accumulating unit 42 as the operation time of the heat pump unit 10 increases. The clothes 80 in the washing / drying chamber 20 can be dried while keeping the temperature in the drying chamber 20 substantially constant, and accordingly, fluctuations in the temperature of the drying gas 50 flowing into the evaporator 14 can be suppressed.

したがって、実施の形態２の洗濯乾燥機においても、ヒートポンプユニット１０における冷凍サイクルを安定して継続的に運転させながら洗濯乾燥室２０内の衣類８０の洗濯乾燥を行なうことができる。   Therefore, also in the washing and drying machine of the second embodiment, the clothes 80 in the washing and drying chamber 20 can be washed and dried while the refrigeration cycle in the heat pump unit 10 is stably and continuously operated.

さらに、実施の形態２の洗濯乾燥機においては、たとえば、第２の蓄熱ユニット４２ｂを用いる必要がない場合には、第２の流入量調節ユニット４１ｂの電動弁を完全に閉じて第２の蓄熱ユニット４２ｂへの乾燥用気体５０の流入を阻止しておき、洗濯乾燥室２０内の温度を大幅に低下させる必要が生じた場合には、第２の流入量調節ユニット４１ｂの電動弁を開いて第２の蓄熱ユニット４２ｂに乾燥用気体５０を流入させ、本流路３１を流れる低湿高温の乾燥用気体５０ａへの低湿低温の乾燥用気体５０ｂの合流量を増加させて、温度をさらに低下させた乾燥用気体５０ｃを洗濯乾燥室２０内に流入させることも可能である。   Furthermore, in the washer / dryer of the second embodiment, for example, when it is not necessary to use the second heat storage unit 42b, the electric valve of the second inflow amount adjusting unit 41b is completely closed to provide the second heat storage unit. When it is necessary to prevent the drying gas 50 from flowing into the unit 42b and to greatly reduce the temperature in the washing / drying chamber 20, the electric valve of the second inflow rate adjusting unit 41b is opened. The drying gas 50 was caused to flow into the second heat storage unit 42b, and the combined flow rate of the low-humidity low-temperature drying gas 50b flowing into the low-humidity high-temperature drying gas 50a flowing through the main flow path 31 was increased, thereby further reducing the temperature. It is also possible to allow the drying gas 50 c to flow into the washing / drying chamber 20.

また、たとえば図６の模式的拡大構成図に示すように、洗濯乾燥室２０内の衣類８０を洗濯するために、たとえば水道などの液体供給ユニット９０から液体用供給路９１に放出されたたとえば冷水などの液体９２ａは、第１の蓄熱ユニット４２ａから熱が与えられて温度が上昇し、たとえば温水などの中温の液体９２ｂとなる。その後、第２の蓄熱ユニット４２ｂから液体９２ｂに熱が与えられて温度がさらに上昇し、たとえば高温水などの高温の液体９２ｃとなって、洗濯乾燥室２０内に流れ込む。   For example, as shown in the schematic enlarged configuration diagram of FIG. 6, in order to wash the clothes 80 in the washing / drying chamber 20, for example, cold water discharged from the liquid supply unit 90 such as tap water to the liquid supply path 91, for example. The liquid 92a is heated by the first heat storage unit 42a to rise in temperature, and becomes a medium temperature liquid 92b such as hot water. Thereafter, heat is applied to the liquid 92b from the second heat storage unit 42b, and the temperature further rises to become a high-temperature liquid 92c such as high-temperature water, for example, and flows into the washing / drying chamber 20.

このように、実施の形態２の洗濯乾燥機においても、従来の特許文献１に記載の衣類乾燥装置のように熱バランス手段において圧縮機の入力に相当する熱量を外部に捨てることなく蓄熱ユニット４２に蓄えることができ、蓄熱ユニット４２に蓄えられた熱を洗濯乾燥室２０内に供給される冷水を温水または高温水にするのに有効利用して衣類８０の洗濯を行なうことができる。   Thus, also in the washing and drying machine of Embodiment 2, the heat storage unit 42 without throwing away the amount of heat corresponding to the input of the compressor in the heat balance means as in the conventional clothes drying apparatus described in Patent Document 1. The clothes 80 can be washed by effectively using the heat stored in the heat storage unit 42 to make the cold water supplied into the washing / drying chamber 20 hot or hot.

したがって、実施の形態２の洗濯乾燥機においても、上記の熱の有効利用の結果として、たとえば衣類８０の洗濯時に衣類８０とともに洗濯乾燥室２０内に投入される洗剤等を高温の液体９２ｃで溶けやすくすることができるため、衣類８０の洗濯効果を高めることができる。   Therefore, also in the washing / drying machine of the second embodiment, as a result of the effective use of the heat, for example, the detergent or the like put into the washing / drying chamber 20 together with the clothes 80 at the time of washing the clothes 80 is dissolved in the high temperature liquid 92c. Since it can make it easy, the washing effect of clothing 80 can be heightened.

本実施の形態における上記以外の説明は、実施の形態１と同様であるため、その説明については省略する。   Since the description other than the above in the present embodiment is the same as that in the first embodiment, the description thereof is omitted.

今回開示された実施の形態はすべての点で例示であって制限的なものではないと考えられるべきである。本発明の範囲は上記した説明ではなくて特許請求の範囲によって示され、特許請求の範囲と均等の意味および範囲内でのすべての変更が含まれることが意図される。   The embodiment disclosed this time should be considered as illustrative in all points and not restrictive.
