Description

本発明は、ヒートポンプ装置を用いた除湿加温装置、および同装置を備えた衣類等の乾燥をおこなう衣類乾燥機に関するものである。   The present invention relates to a dehumidifying and warming device using a heat pump device and a clothes dryer for drying clothes and the like equipped with the device.

従来、この種の除湿加温装置を備えた衣類乾燥機は、図３に示すような構成が知られている（例えば、特許文献１参照）。図３は、特許文献１に記載された衣類乾燥装置の系統図を示したものである。図３において、圧縮機５１、凝縮器５２、排熱器５３、絞り手段５４および蒸発器５５を冷媒が循環する管路５６で連結し、ヒートポンプ装置５７を構成している。乾燥用空気を流す風回路５８は、乾燥用空気を加熱する凝縮器５２と、乾燥させる衣類等を入れる乾燥庫５９と、乾燥用空気を冷却し除湿する蒸発器５５を乾燥用空気が流れる風路によって連結するように構成している。   Conventionally, the clothes dryer provided with this kind of dehumidification warming apparatus has a structure as shown in FIG. 3 (for example, refer patent document 1). FIG. 3 is a system diagram of the clothes drying apparatus described in Patent Document 1. In FIG. 3, a compressor 51, a condenser 52, a heat exhauster 53, a throttle means 54, and an evaporator 55 are connected by a pipeline 56 through which a refrigerant circulates to constitute a heat pump device 57. The wind circuit 58 for flowing the drying air includes a condenser 52 that heats the drying air, a drying chamber 59 that holds clothes to be dried, and an evaporator 55 that cools and dehumidifies the drying air. It connects so that it may connect with a road.

排熱器５３は、凝縮器５２と絞り手段５４との間に設置されるとともに、風回路５８とは別の風回路６０に配設され、送風機６１で送風された外気と排熱器５３を流れる冷媒が熱交換し、冷媒の熱の一部を放出させるものであり、冷媒の温度上昇を低減するようにしている。ヒートポンプ装置５７の状態を検知する検知手段６２は、圧縮機５１から冷媒が吐出する管路５６に設けたサーミスタ６３により冷媒吐出温度を検知し、圧縮機５１と送風機６１を制御する。   The heat exhauster 53 is installed between the condenser 52 and the throttle means 54, and is disposed in a wind circuit 60 different from the wind circuit 58. The heat exhauster 53 removes the outside air blown by the blower 61 and the heat exhaustor 53. The flowing refrigerant exchanges heat and releases a part of the heat of the refrigerant so as to reduce the temperature rise of the refrigerant. The detection means 62 for detecting the state of the heat pump device 57 detects the refrigerant discharge temperature by the thermistor 63 provided in the pipe 56 through which the refrigerant is discharged from the compressor 51, and controls the compressor 51 and the blower 61.

なお、矢印Ａは、風回路５８を流れる乾燥用空気の流れを示し、矢印Ｂは、風回路６０を流れる冷却用の外気の流れを示し、矢印Ｃは、管路５６を流れる冷媒の流れを示している。   The arrow A indicates the flow of drying air flowing through the wind circuit 58, the arrow B indicates the flow of cooling outside air flowing through the wind circuit 60, and the arrow C indicates the flow of refrigerant flowing through the pipe 56. Show.

次に、上記衣類乾燥装置の動作について説明する。乾燥運転を開始すると、圧縮機５１と風回路５８に設けた送風機６４が作動し、送風機６４によって風回路５８に乾燥用空気が送風される。乾燥用空気は、凝縮器５２からの放熱で加熱され、温風となって乾燥庫５９に導入される。乾燥庫５９内で衣類と接触した乾燥用空気は、湿った衣類から水分を奪って衣類を乾燥させる。   Next, the operation of the clothes drying apparatus will be described. When the drying operation is started, the blower 64 provided in the compressor 51 and the wind circuit 58 is operated, and the drying air is blown to the wind circuit 58 by the blower 64. The drying air is heated by heat radiation from the condenser 52 and is introduced into the drying chamber 59 as warm air. The drying air that has come into contact with the clothes in the drying cabinet 59 removes moisture from the wet clothes and dries the clothes.

乾燥用空気は、蒸発のための熱量として顕熱を与えられるため温度が低下するが、衣類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となる。衣類と接触する前後の乾燥用空気のエンタルピはほぼ一定である。高湿となった乾燥用空気は、蒸発器５５で冷却され、潜熱を奪われ結露して除湿される。除湿されて絶対温度が低下した乾燥用空気は、再び凝縮器５２で加熱される。   The drying air is provided with sensible heat as the amount of heat for evaporation, and thus the temperature is lowered. However, the drying air contains water vapor having substantially the same latent heat released from the clothing and becomes highly humid. The enthalpy of the drying air before and after coming into contact with clothing is almost constant. The drying air that has become highly humid is cooled by the evaporator 55, deprived of latent heat, dewed and dehumidified. The drying air which has been dehumidified and whose absolute temperature has been lowered is heated again by the condenser 52.

一方、ヒートポンプサイクルは、圧縮機５１で圧縮された高温高圧のガス冷媒が凝縮器５２で乾燥用空気に熱を奪われ凝縮し液化する。凝縮器５２を出た冷媒は排熱器５３に入り、送風機６１で送風された外気と熱交換し、冷媒の熱の一部を排熱する。次に、高圧の冷媒が絞り手段５４で減圧され、低温低圧となって蒸発器５５で乾燥用空気から熱を奪い圧縮機５１に戻る。   On the other hand, in the heat pump cycle, the high-temperature and high-pressure gas refrigerant compressed by the compressor 51 takes heat from the drying air by the condenser 52 and condenses and liquefies. The refrigerant exiting the condenser 52 enters the heat exhauster 53, exchanges heat with the outside air blown by the blower 61, and exhausts a part of the heat of the refrigerant. Next, the high-pressure refrigerant is depressurized by the throttle means 54, becomes low temperature and low pressure, takes heat from the drying air by the evaporator 55, and returns to the compressor 51.

冷媒によって蒸発器５５で奪った熱量に、圧縮機５１の入力から得られる熱量を加えた熱量が、凝縮器５２から放出されるが、排熱器５３によって圧縮機５１の入力に相当する熱量を予め外部に放熱し、凝縮器５２からの放熱量を一定の値でバランスするようにしている。   The amount of heat obtained by adding the amount of heat obtained from the input of the compressor 51 to the amount of heat deprived by the evaporator 55 by the refrigerant is released from the condenser 52, but the amount of heat corresponding to the input of the compressor 51 is discharged by the heat exhaustor 53. Heat is radiated to the outside in advance, and the amount of heat radiated from the condenser 52 is balanced at a constant value.

A first wind circuit provided, and a second wind circuit provided with a second air blowing means for disposing a heat exhausting section provided in the condenser and blowing air to the heat exhausting section, The air circuit is dehumidified and heated, and the heat of the condenser is discharged by the second wind circuit.

これによって、凝縮器の一部を排熱部として利用するため、余分な配管がいらず、除湿加温装置をコンパクトに構成することができる。   Thereby, since a part of the condenser is used as the heat exhausting section, no extra piping is required, and the dehumidifying and warming device can be configured compactly.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

（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除湿加温装置の系統図、図２は、同除湿加温装置を備えた衣類乾燥機の系統図である。 (Embodiment 1)
FIG. 1 is a system diagram of a dehumidifying and warming apparatus according to the first embodiment of the present invention, and FIG. 2 is a system diagram of a clothes dryer provided with the dehumidifying and warming apparatus.

図１および図２において、ヒートポンプ装置１は、冷媒を圧縮する圧縮機２と、圧縮後の高温高圧の冷媒の熱を放熱する凝縮器３と、高圧の冷媒の圧力を減圧するためのキャピラリーチューブからなる絞り手段４と、減圧されて低圧となった冷媒が周囲から熱を奪う蒸発器５を冷媒が循環するように管路６で連結している。   1 and 2, a heat pump device 1 includes a compressor 2 that compresses a refrigerant, a condenser 3 that dissipates heat of the compressed high-temperature and high-pressure refrigerant, and a capillary tube that reduces the pressure of the high-pressure refrigerant. The throttle means 4 is connected to the evaporator 6 through which the refrigerant whose pressure has been reduced to low pressure takes heat from the surroundings, and the refrigerant is circulated by a pipe 6.

凝縮器３は、一定間隔で平行に並べられ、相互間を空気が流動するフィン３ａと、このフィン３ａと接し内部に冷媒が流動する管路６としての伝熱管３ｂとからなる一般的なフィンチューブ型の熱交換器で構成されており、伝熱管３ｂの管軸方向に加熱部７と排熱部８が設けられている。フィン３ａは、アルミニウム等の薄板で形成し、管路６を構成する伝熱管３ｂは、銅管で形成している。   The condenser 3 is arranged in parallel at regular intervals, and is a general fin composed of fins 3a in which air flows between each other, and heat transfer tubes 3b as conduits 6 in contact with the fins 3a and in which refrigerant flows. It is comprised with the tube-type heat exchanger, and the heating part 7 and the exhaust heat part 8 are provided in the pipe-axis direction of the heat exchanger tube 3b. The fin 3a is formed of a thin plate such as aluminum, and the heat transfer tube 3b constituting the pipe line 6 is formed of a copper tube.

加熱部７は、第１の風回路９内に設置されており、第１の送風機（第１の送風手段）１０で送風された空気は蒸発器５を通過した後、加熱部７を通過する。排熱部８は、第１の風回路９に隣接して形成された第２の風回路１１内に設置されており、第２の送風機（第２の送風手段）１２で送風された空気が通過する。   The heating unit 7 is installed in the first wind circuit 9, and the air blown by the first blower (first blowing unit) 10 passes through the evaporator 5 and then passes through the heating unit 7. . The exhaust heat unit 8 is installed in a second wind circuit 11 formed adjacent to the first wind circuit 9, and the air blown by the second blower (second blower means) 12 is pass.

凝縮器３に構成した加熱部７は排熱部８より大きく、第１の風回路９内に設置された加熱部７の通風断面積イは、第２の風回路１１内に設置された排熱部８の通風断面積ロより大きく形成している。また、加熱部７の空気流入面と、排熱部８の空気流入面は同一面上にあり、加熱部７と排熱部８ともに空気は冷媒の流れ方向に対して相対的に対向流となるように流れている。   The heating unit 7 configured in the condenser 3 is larger than the exhaust heat unit 8, and the ventilation cross-sectional area i of the heating unit 7 installed in the first wind circuit 9 is the exhaust unit installed in the second wind circuit 11. It is formed larger than the ventilation cross-sectional area B of the heat part 8. Further, the air inflow surface of the heating unit 7 and the air inflow surface of the exhaust heat unit 8 are on the same surface, and the air is relatively opposed to the refrigerant flow direction in both the heating unit 7 and the exhaust heat unit 8. It is flowing to become.

なお、矢印Ａは、第１の風回路９を流れる空気の流れを示し、矢印Ｂは、第２の風回路１１を流れる冷却用の外気の流れを示し、矢印Ｃは、管路６を流れる冷媒の流れを示している。   The arrow A indicates the flow of air flowing through the first wind circuit 9, the arrow B indicates the flow of outside air for cooling flowing through the second wind circuit 11, and the arrow C flows through the pipe 6. The flow of the refrigerant is shown.

以上のように構成された除湿加温装置は、凝縮器３の一部を加熱部７とし、他の部分を排熱部８としているので、別途排熱器を設ける必要がなく、排熱器を繋ぐ配管がなくなり、除湿加温装置をコンパクトに構成することができる。   In the dehumidifying / heating apparatus configured as described above, a part of the condenser 3 is used as the heating unit 7 and the other part is used as the exhaust heat unit 8, so that it is not necessary to provide a separate heat exhaust unit. Therefore, the dehumidifying / heating apparatus can be configured compactly.

また、凝縮器３内を流れる冷媒は過熱蒸気の状態で流入し、温度を下げて気液二相状態となり飽和温度で流動し、完全に液化するとさらに温度を下げて過冷却状態となり、凝縮器３から流出する。凝縮器３内では、このような温度変化がおこるため、空気の流れ方向を冷媒の流れ方向と相対的に対向流とすることにより、空気と冷媒の平均温度差を大きくとることができるため効率よく熱交換でき、さらに、加熱部７と排熱部８をコンパクトに構成することができる。   Further, the refrigerant flowing in the condenser 3 flows in the state of superheated steam, lowers the temperature to become a gas-liquid two-phase state, flows at the saturation temperature, and when completely liquefied, further lowers the temperature to become the supercooled state. Out of 3 Since such a temperature change occurs in the condenser 3, the average temperature difference between the air and the refrigerant can be increased by setting the air flow direction to be a counter flow relatively to the refrigerant flow direction. Heat can be exchanged well, and the heating unit 7 and the exhaust heat unit 8 can be configured compactly.

次に、このように構成された除湿加温装置を衣類乾燥機に用いた場合の動作について説明する。加熱部７を設置した第１の風回路９は、衣類等の乾燥対象を収容する乾燥庫１３と連結され、第１の送風機１０で送風された空気が循環する循環風路を形成している。排熱部８を設置した第２の風回路１１は、第２の送風機１２で外気を吸い込み、排熱部８を通過して外部に排気する。   Next, an operation when the dehumidifying / heating apparatus configured as described above is used in a clothes dryer will be described. The 1st wind circuit 9 which installed the heating part 7 is connected with the drying store | warehouse | chamber 13 which accommodates drying objects, such as clothing, and forms the circulation air path through which the air ventilated with the 1st air blower 10 circulates. . The 2nd wind circuit 11 which installed the heat exhaustion part 8 suck | inhales external air with the 2nd air blower 12, passes the heat exhaustion part 8, and exhausts outside.

乾燥運転を開始すると圧縮機２および第１の送風機１０が作動する。第１の送風機１０によって乾燥用空気が加熱部７を通過し、加熱部７からの放熱で加熱されて温風となり、乾燥庫１３に送られる。乾燥庫１３内で衣類と接触した乾燥用空気は、衣類から水分を奪って衣類を乾燥する。   When the drying operation is started, the compressor 2 and the first blower 10 are operated. Drying air passes through the heating unit 7 by the first blower 10, is heated by heat radiation from the heating unit 7, becomes warm air, and is sent to the drying cabinet 13. The drying air that has come into contact with the clothes in the drying cabinet 13 removes moisture from the clothes and dries the clothes.

乾燥用空気は、蒸発のための熱量として顕熱を与えられるため温度が低下するが、衣類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。衣類と接触する前後の乾燥空気のエンタルピはほぼ一定である。高湿となった乾燥用空気は、蒸発器５において冷却され、潜熱を奪われ結露して除湿される。除湿されて絶対湿度が低下した乾燥用空気は再び加熱部７で加熱される。   The drying air is given a sensible heat as an amount of heat for evaporation, and thus the temperature is lowered. However, the drying air contains water vapor having substantially the same latent heat released from the clothing and becomes high-humidity air. The enthalpy of dry air before and after coming into contact with clothing is almost constant. The drying air that has become highly humid is cooled in the evaporator 5, deprived of latent heat, dewed and dehumidified. The drying air that has been dehumidified and has a reduced absolute humidity is heated again by the heating unit 7.

一方、ヒートポンプサイクルは、圧縮機２で圧縮された高温高圧のガス冷媒が加熱部７で乾燥用空気に熱を与え凝縮するとともに、排熱部８で一部の熱を外部空気に排出し凝縮する。この際、乾燥運転開始直後等、加熱量が多く必要な場合は、第２の送風機１２を停止、もしくは回転数を低減することにより排熱量を低減し、加熱量を増やすことができる。   On the other hand, in the heat pump cycle, the high-temperature and high-pressure gas refrigerant compressed by the compressor 2 gives heat to the drying air by the heating unit 7 and condenses, and the exhaust heat unit 8 discharges some heat to the outside air and condenses it. To do. At this time, when a large amount of heating is required, such as immediately after the start of the drying operation, the amount of exhaust heat can be reduced and the amount of heating can be increased by stopping the second blower 12 or reducing the rotational speed.

次に、高圧の冷媒が絞り手段４で減圧され、低温低圧となり、蒸発器５で乾燥用空気から熱を奪い再び圧縮機２に戻る。冷媒によって蒸発器５で奪った熱量に圧縮機２の入力から得られる熱量を加えた熱量が、凝縮器３から放熱されるが、排熱部８によって圧縮機２の入力に相当する熱量を予め外部に放出するため、加熱部７からの加熱量は一定の値でバランスしている。   Next, the high-pressure refrigerant is depressurized by the throttle means 4 to become a low temperature and a low pressure, and the evaporator 5 takes heat from the drying air and returns to the compressor 2 again. A heat amount obtained by adding the heat amount obtained from the input of the compressor 2 to the heat amount taken away by the evaporator 5 by the refrigerant is radiated from the condenser 3. In order to discharge to the outside, the heating amount from the heating unit 7 is balanced at a constant value.

ここで、圧縮機２の入力に相当する熱量、つまり、排熱部８から排出する熱量と、乾燥用空気を加熱する熱量、つまり、加熱部７で乾燥用空気に与える熱量では、後者の方が大きいため、加熱部７を排熱部８より大きくすることにより、加熱と排熱をバランスよくおこなえるため、除湿加温装置をコンパクトにすることができる。   Here, the amount of heat corresponding to the input of the compressor 2, that is, the amount of heat discharged from the exhaust heat unit 8 and the amount of heat for heating the drying air, that is, the amount of heat given to the drying air by the heating unit 7 are the latter one. Therefore, by making the heating unit 7 larger than the exhaust heat unit 8, heating and exhaust heat can be performed in a well-balanced manner, so that the dehumidifying and warming device can be made compact.

以上のように、凝縮器３に設けた加熱部７と蒸発器５を配設し、蒸発器５と加熱部７に送風する第１の送風機１０を有した第１の風回路９と、凝縮器３に設けた排熱部８を配設し、排熱部８に送風する第２の送風機１２を有した第２の風回路１１とを備え、第１の風回路９によって除湿加温し、第２の風回路１１によって凝縮器３の熱を排出するようにしたものであり、凝縮器３の一部を加熱部７とし、他の部分を排熱部８としたため、凝縮器３の一部を排熱部８として利用することができ、別途排熱器を設ける必要がなく、排熱器を繋ぐ配管がなくなり、除湿加温装置をコンパクトに構成することができる。   As described above, the heating unit 7 and the evaporator 5 provided in the condenser 3 are disposed, the first air circuit 9 having the first blower 10 that blows air to the evaporator 5 and the heating unit 7, and the condensation And a second wind circuit 11 having a second blower 12 that blows air to the heat exhaust section 8, and is dehumidified and heated by the first wind circuit 9. Since the heat of the condenser 3 is discharged by the second wind circuit 11, a part of the condenser 3 is used as the heating unit 7, and the other part is used as the exhaust heat unit 8. A part of the heat can be used as the heat exhausting unit 8, and it is not necessary to provide a separate heat exhauster. There is no piping connecting the heat exhauster, and the dehumidifying and warming device can be configured compactly.

また、凝縮器３に加熱部７と排熱部８を設け、加熱部７の通風断面積イを排熱部８の通風断面積ロより大きくしたことにより、乾燥用空気の加熱量を排熱量より大きくすることができ、乾燥用空気の加熱を不足なく最適におこなうことができるとともに、加熱部７と排熱部８での熱交換がバランスよくおこなえるようになり、除湿加温装置のコンパクト化が図れる。   Further, the heating unit 7 and the exhaust heat unit 8 are provided in the condenser 3, and the ventilation cross-sectional area I of the heating unit 7 is made larger than the ventilation cross-sectional area B of the exhaust heat unit 8, thereby reducing the heating amount of the drying air. It can be made larger, and the drying air can be heated optimally without shortage, and the heat exchange between the heating unit 7 and the exhaust heat unit 8 can be performed in a well-balanced manner, and the dehumidifying and heating device can be made compact. Can be planned.

また、凝縮器３は、一定間隔で平行に並べられ、相互間を空気が流動するフィン３ａと、このフィン３ａと接し内部に冷媒が流動する伝熱管３ｂとからなり、加熱部７と排熱部８とを伝熱管３ｂの管軸方向に設置したものであり、従来技術では凝縮器を出た後に排熱器を設けているため、液冷媒と熱交換し排熱させることとなり、効率よく排熱させることができず排熱器を大きくする必要があるのに対し、管軸方向に加熱部７と排熱部８を設けたことにより、排熱部８内の冷媒は液だけでなく、蒸気や気液二相状態となり、凝縮過程を伴った効率のよい排熱ができるため、排熱部８を小型化でき、さらにコンパクトな除湿加温装置を提供することができる。   The condenser 3 is arranged in parallel at regular intervals, and includes fins 3a through which air flows and heat transfer tubes 3b through which the refrigerant flows in contact with the fins 3a. The portion 8 is installed in the direction of the tube axis of the heat transfer tube 3b, and in the prior art, a heat exhauster is provided after exiting the condenser. While it is not possible to exhaust heat and it is necessary to increase the size of the heat exhauster, by providing the heating unit 7 and the exhaust heat unit 8 in the tube axis direction, the refrigerant in the exhaust heat unit 8 is not only liquid. In addition, since it is in a vapor or gas-liquid two-phase state and efficient exhaust heat accompanied by a condensation process can be performed, the exhaust heat unit 8 can be reduced in size, and a more compact dehumidifying and warming device can be provided.

また、第１の風回路９内に設置された加熱部７の空気流入面と、第２の風回路１１内に設置された排熱部８の空気流入面とを同一面上に構成したものであり、排熱部８の風の流れ方向を加熱部７と同方向にすることにより、加熱部７と同様の高効率な熱交換効率を得ることができ、さらに排熱部８をコンパクトにすることができる。   Further, the air inflow surface of the heating unit 7 installed in the first wind circuit 9 and the air inflow surface of the exhaust heat unit 8 installed in the second wind circuit 11 are configured on the same surface. By making the flow direction of the wind of the exhaust heat unit 8 the same as that of the heating unit 7, it is possible to obtain the same highly efficient heat exchange efficiency as the heating unit 7, and further reducing the exhaust heat unit 8 to be compact. can do.

また、衣類乾燥機に本発明の除湿加温装置を搭載することにより、衣類乾燥機の小型化を促進することができる。   In addition, by installing the dehumidifying and warming device of the present invention in a clothes dryer, it is possible to promote downsizing of the clothes dryer.

以上のように、本発明にかかる除湿加温装置は、冷媒の熱の一部を効果的に放出し、除湿加温装置をコンパクトに構成することができるので、除湿加温装置および衣類乾燥機として有用である。   As described above, the dehumidifying / warming device according to the present invention can effectively release part of the heat of the refrigerant, and the dehumidifying / warming device can be configured compactly.
