Description

本発明は、略水平方向または斜め方向に回転中心軸を有する回転ドラム内で洗濯、すすぎ、脱水、乾燥などの各行程を逐次制御するドラム式洗濯乾燥機に関するものである。   The present invention relates to a drum-type washing and drying machine that sequentially controls each process such as washing, rinsing, dewatering, and drying in a rotating drum having a rotation center axis in a substantially horizontal direction or an oblique direction.

従来、この種のドラム式洗濯乾燥機は図７に示すように構成していた。以下、その構成について説明する。   Conventionally, this type of drum type washing and drying machine is configured as shown in FIG. Hereinafter, the configuration will be described.

図７に示すように、筐体１内に、複数のサスペンション２とダンパー３で水槽４を支持し、この水槽４の開口部をドア５により開閉し、水槽４内に回転ドラム６を回転自在に配設している。回転ドラム６を洗濯モータ７により駆動し、回転ドラム６に多数の通水孔８とバッフル９を設けている。洗濯用給水弁１０は水槽４内に給水するもので、冷却水用給水弁１１は冷却水を給水するもので、それぞれ筐体１に設けている。水槽４に排水口１２を設け、この排水口１２を排水弁１３を介して排水経路１４に連通している。   As shown in FIG. 7, a water tank 4 is supported in a housing 1 by a plurality of suspensions 2 and dampers 3, an opening of the water tank 4 is opened and closed by a door 5, and a rotating drum 6 is freely rotatable in the water tank 4. It is arranged. The rotary drum 6 is driven by a washing motor 7, and the water drum 8 and the baffle 9 are provided in the rotary drum 6. The washing water supply valve 10 supplies water into the water tank 4, and the cooling water supply valve 11 supplies cooling water and is provided in the housing 1. A drainage port 12 is provided in the water tank 4, and the drainage port 12 communicates with a drainage path 14 via a drainage valve 13.

送風機１５は吹き出し口１６を介して水槽４内に送風するもので、この送風機１５にヒータ１７を連通し、水槽４内と送風機１５とを熱交換器１８により連通し、冷却水用給水弁１１に直結され、熱交換器１８に開口した冷却水ホース１９とによって、一連の乾燥循環経路を構成している（例えば、特許文献１参照）。   The blower 15 blows air into the water tank 4 through the blowout port 16. The heater 17 is communicated with the blower 15, the water tank 4 and the blower 15 are communicated with the heat exchanger 18, and the cooling water supply valve 11 is connected. A cooling water hose 19 that is directly connected to the heat exchanger 18 and opens to the heat exchanger 18 constitutes a series of drying circulation paths (see, for example, Patent Document 1).

上記構成において動作を説明する。回転ドラム６内に洗濯物を投入し洗濯行程を開始すると、洗濯用給水弁１０が開き水槽４内に所定の水位まで給水する。つぎに、回転ドラム６が約５０ｒ／ｍｉｎで回転し、投入された衣類はバッフル８によって持ち上げられては落下を繰り返し、洗剤水と水面に落下したときの衝撃力によって洗浄される。洗濯行程が終わると排水弁１３を駆動し、洗濯水を排水経路１４を通して排水する。排水が終わると回転ドラム６を約１０００ｒ／ｍｉｎで高速回転し脱水を行う。さらに脱水行程が終了すると乾燥行程へ移行する。   The operation in the above configuration will be described. When the laundry is put into the rotating drum 6 and the washing process is started, the washing water supply valve 10 is opened to supply water into the water tank 4 to a predetermined water level. Next, the rotary drum 6 rotates at about 50 r / min, and the thrown-in garment is lifted by the baffle 8 and repeatedly dropped, and is washed by the detergent water and the impact force when dropped on the water surface. When the washing process ends, the drain valve 13 is driven, and the washing water is drained through the drain passage 14. When drainage is completed, the rotating drum 6 is rotated at a high speed of about 1000 r / min to perform dehydration. When the dehydration process is completed, the process proceeds to the drying process.

乾燥行程では洗濯行程と同様に、回転ドラム６を駆動し、回転ドラム６内の洗濯物を撹拌しながら、送風機１５とヒータ１７によって加熱された熱風を回転ドラム６内の衣類に吹き出し口１５から吹き付け、衣類内に含まれた水分を加熱し蒸発させる。さらに、蒸気を含む高温の空気は熱交換器１８内に送られ、冷却水用給水弁１１から冷却水ホース１９を介して、熱交換器１８内に供給された冷却水と混合し、熱交換を行い冷却除湿される。さらに、除湿された空気はヒータ１７によって再び加熱され、回転ドラム６内に送られ衣類の乾燥を行う。これによって一連の乾燥サイクルを形成している。
特開平９−２１５８９３号公報 In the drying process, similarly to the washing process, the rotating drum 6 is driven to stir the laundry in the rotating drum 6, and hot air heated by the blower 15 and the heater 17 is applied to the clothes in the rotating drum 6 from the outlet 15. Spray and heat and evaporate moisture contained in clothing. Further, high-temperature air containing steam is sent into the heat exchanger 18 and mixed with the cooling water supplied from the cooling water supply valve 11 through the cooling water hose 19 to the heat exchanger 18 to exchange heat. To cool and dehumidify. Further, the dehumidified air is heated again by the heater 17 and sent into the rotary drum 6 to dry the clothes. This forms a series of drying cycles.

しかしながら、このような従来の構成では、ダクト状の熱交換器１８を別途構成しなければならず、限られた筐体１内のスペースの中で十分な容積の確保が困難であった。さらに、乾燥後の乾きむらを低減するためには、循環風量を上げるのが効果的であるが、冷却水と混合して除湿するタイプの熱交換器１８の場合、風量を上げると冷却水を巻き込み、ヒータ１７を濡らしたり、乾いた衣類を再び濡らしたりするという問題があった。   However, in such a conventional configuration, the duct-shaped heat exchanger 18 must be separately configured, and it has been difficult to secure a sufficient volume in the limited space in the housing 1. Furthermore, in order to reduce drying unevenness after drying, it is effective to increase the circulating air volume. However, in the case of the heat exchanger 18 of the type that is dehumidified by mixing with cooling water, if the air volume is increased, the cooling water is reduced. There is a problem that the heater 17 is caught and the dry clothes are wetted again.

本発明は上記従来の課題を解決するもので、、コンパクトな筐体内のスペースで熱交換を行うようにするとともに、風量を上げても冷却水の巻き込みを抑制できるようにし、乾燥後の乾きむらを低減することを目的としている。   The present invention solves the above-described conventional problems, and heat exchange is performed in a space in a compact housing, and the entrainment of cooling water can be suppressed even when the air volume is increased.

A blowing path that opens and closes by the body, sends warm air into the rotating drum by the blowing means, heats the warm air blown by the blowing means by the heating means, and guides the warm air blown by the blowing means into the rotating drum. It is configured integrally with the water tank, a plate-shaped heat exchanger is fixed in the air flow path, and the cooling water is supplied to the heat exchanger by the cooling means. The heat exchanger has a cooling surface facing the air blowing direction. It is configured to be inclined and attached.

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、従来例と同じ構成のものは同一符号を付して説明を省略する。また、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. In addition, the thing of the same structure as a prior art example attaches | subjects the same code | symbol, and abbreviate | omits description. Further, the present invention is not limited by this embodiment.

（実施の形態１）
図１に示すように、吸引ダクト２０は、水槽２１と一体に構成し、水槽２１のの一部に吸気口２２を設けている。この吸引ダクト２０内に板状の熱交換器２３を固定している。ファンケース２４は、水槽２１の後部に設け、回転ドラム６内に温風を送風する送風ファン（送風手段）２５と、この送風ファン２５により送風される温風を加熱するヒータ（加熱手段）２６とを設けている。ダクト２７は、吸引ダクト２０とファンケース２４とを連結し、これら吸引ダクト２０、ファンケース２４およびダクト２７で送風経路２８を構成し、送風経路２８の一部を水槽２１と一体に構成するとともに、送風ファン２５により送風される温風を回転ドラム６内に導くよう構成している。 (Embodiment 1)
As shown in FIG. 1, the suction duct 20 is configured integrally with a water tank 21, and an intake port 22 is provided in a part of the water tank 21. A plate-shaped heat exchanger 23 is fixed in the suction duct 20. The fan case 24 is provided at the rear of the water tank 21, and a blower fan (blower unit) 25 that blows hot air into the rotary drum 6 and a heater (heater unit) 26 that heats the hot air blown by the blower fan 25.

The hot air blown by the blower fan 25 is guided into the rotary drum 6.

冷却用給水弁２９は冷却水ホース３０を通して熱交換器２３に冷却水を給水するもので、冷却用給水弁２９と冷却水ホース３０とで冷却手段を構成している。ここで、熱交換器２３は冷却面を送風方向に向かって、傾斜させて取り付けている。   The cooling water supply valve 29 supplies cooling water to the heat exchanger 23 through the cooling water hose 30, and the cooling water supply valve 29 and the cooling water hose 30 constitute cooling means. Here, the heat exchanger 23 is attached so that the cooling surface is inclined toward the blowing direction.

上記構成において動作を説明する。なお、洗濯行程から脱水行程までの動作は従来例の動作と同じであるので説明を省略する。   The operation in the above configuration will be described. Since the operation from the washing process to the dehydration process is the same as the operation of the conventional example, the description thereof is omitted.

乾燥行程において、送風ファン２５によって送風された温風がヒータ２６によって加熱され、吹き出し口３１から回転ドラム６内に送風される。加熱された温風は、回転ドラム６内の湿った衣類と熱交換を行い、水分を含んだ状態となり、吸気口２２より吸引ダクト２０内へ送られる。このとき、冷却水は板状の傾斜した熱交換器２３の表面を流れ落ち、熱交換器２３を冷却する。   In the drying process, the warm air blown by the blower fan 25 is heated by the heater 26 and blown into the rotary drum 6 from the blowout port 31. The heated hot air exchanges heat with the wet clothing in the rotary drum 6, enters a state containing moisture, and is sent into the suction duct 20 from the intake port 22.

Therefore, there is no scattering of the cooling water as in the conventional case, and the cooling water can be increased even if the air volume is increased. Can be suppressed, the heater 26 is not wetted, and uneven drying after drying can be reduced.

（実施の形態２）
図２に示すように、熱交換器３２は、板状に形成し、送風経路を構成する吸引ダクト（いずれも図示せず）内に、冷却面を送風方向に向かって傾斜させて取り付けている。この熱交換器３２の冷却面を送風方向に向かって階段状に形成している。他の構成は上記実施の形態１と同じである。 (Embodiment 2)
As shown in FIG. 2, the heat exchanger 32 is formed in a plate shape, and is attached with a cooling surface inclined toward the blowing direction in a suction duct (none of which is shown) constituting the blowing path. . The cooling surface of the heat exchanger 32 is formed in a step shape toward the blowing direction. Other configurations are the same as those of the first embodiment.

上記構成において動作を説明する。なお、乾燥行程での基本的な動作は上記実施の形態１と同じであるので説明を省略する。   The operation in the above configuration will be described. The basic operation in the drying process is the same as that in the first embodiment, and the description thereof is omitted.

乾燥行程において、冷却水が傾斜した熱交換器３２の表面を流れ落ちるとき、冷却水が熱交換器３２の上流から下流へ流れ落ちる時間を長くできるとともに、熱交換面積も広くでき、乾燥性能を上げることができる。   In the drying process, when the cooling water flows down the inclined surface of the heat exchanger 32, the cooling water can flow longer from the upstream side to the downstream side of the heat exchanger 32, and the heat exchange area can be widened to improve the drying performance. Can do.
