It relates to a vertical washing/drying machine equipped with a drying function.

一般的に洗濯乾燥機は、衣類を収容する内槽の底部に回転翼を設け、内槽及び回転翼を回転支持する外槽に水を溜めた状態で、回転翼を正逆回転させて洗いを行う。そして、内槽を高速回転させて脱水を終了した後の乾燥工程では、ヒータで加熱された温風を送風ファンにより衣類に吹付ける。温風により衣類に含まれた水分は蒸発し、水分を含んだ空気は循環経路に導かれ、この循環経路に設けられた除湿機構により水分が取り除かれる。また、乾燥工程では温風を内槽の下側や、側面から吹付けて衣類を持ち上げることにより乾燥効率の向上やしわの低減を行っている。 In general, a washer/dryer has rotary blades at the bottom of an inner tub that holds clothes, and rotates the rotary blades forward and backward while water is stored in the inner tub and the outer tub that supports the rotation of the rotary blades. I do. Then, in the drying process after the inner tub is rotated at high speed to finish dehydration, hot air heated by a heater is blown onto the clothes by a blower fan. The warm air evaporates the moisture contained in the clothes, and the moisture-laden air is led to a circulation path, where the moisture is removed by a dehumidifying mechanism provided in the circulation path. In the drying process, hot air is blown from the bottom and sides of the inner tank to lift the clothes, thereby improving drying efficiency and reducing wrinkles.

例えば特許文献１には、乾燥機構より外槽に温風を吹出す外槽吹出し口を設け、洗濯槽に前記温風が通る洗濯槽吹出し孔を設け、前記外槽側から前記外槽吹出し口と前記洗濯槽吹出し孔が貫通して前記乾燥機構より温風を吹出す流路を形成し、前記外槽吹出し口と前記洗濯槽吹出し孔が重なるように、前記洗濯槽の位置を固定して、前記温風を前記外槽側面から前記洗濯槽内の衣類に吹付けている。また、特許文献２には、外槽の内部に、外周面に多数の孔を開設した内槽が鉛直軸回りに回転自由に設置され、内槽の外部に設置された温風噴射機構により内槽に設けられた多数の孔から衣類に温風を吹付けている。また、特許文献３には、回転翼と内槽壁面全周の隙間から衣類に温風を吹付けている。 For example, in Patent Document 1, an outer tub outlet for blowing hot air from a drying mechanism to the outer tub is provided, a washing tub is provided with a washing tub outlet through which the warm air passes, and the outer tub outlet is provided from the outer tub side. and the washing-tub blow-out hole penetrates to form a flow path for blowing hot air from the drying mechanism, and the position of the washing-tub is fixed so that the outer-tub blow-out port and the washing-tub blow-out hole overlap. , the hot air is blown onto the clothes in the washing tub from the side of the outer tub; Further, in Patent Document 2, an inner tank having a large number of holes on the outer peripheral surface is installed inside the outer tank so as to be rotatable around a vertical axis. Hot air is blown onto the clothes from a large number of holes provided in the tub. Further, in Patent Document 3, hot air is blown onto clothes from a gap between the rotating blade and the inner tank wall surface.

特許第６２８６２６１号公報Japanese Patent No. 6286261 特開平１０－７１２９２号公報JP-A-10-71292 特開平０９－７７４号公報JP-A-09-774

これらのような縦型洗濯乾燥機では、洗濯槽の側面から温風を吹付けるため、洗濯槽底部の衣類を衣類がない洗濯槽の上方向に押し広げることが困難となり、しわが低減しにくい。また、送風ファンにより外槽側から内槽に向けて吹出された温風が分散されて内槽に設けられた多数の孔から衣類に吹付けられたり、外槽側から内槽に向けて吹出された温風が分散されて回転翼と内槽壁面全周の隙間から衣類に吹付けられたりするため、個々の衣類に吹付けられる風速と風量が減少し、しわの増加や乾燥効率が低下する。 In such a vertical type washer/dryer, since hot air is blown from the side of the washing tub, it is difficult to push the clothes at the bottom of the washing tub upwards without any clothes, making it difficult to reduce wrinkles. . In addition, the hot air blown from the outer tank side toward the inner tank by the blower fan is dispersed and blown onto the clothes through a large number of holes provided in the inner tank, or is blown from the outer tank side toward the inner tank. The heated air is dispersed and blown onto the clothes through the gap between the rotating blades and the wall surface of the inner tank, reducing the speed and volume of the air blown onto each garment, resulting in increased wrinkles and reduced drying efficiency. do.

The microcomputer 40 is connected to an operation button input circuit 41 connected to each switch 6, 6a, a water level sensor 21, a temperature sensor 26, and a vibration sensor 27, and receives various kinds of information in the user's button operation, washing process, and drying process. receive a signal. An output from the microcomputer 40 is connected to a drive circuit 42, which is connected to the water supply electromagnetic valve 4, the clutch 12, the drain valve 15, the circulation pump 16, the electric motor 13, the blower fan 19, the heater 20, and the like, to open/close, rotate, and rotate these. Control energization. It is also connected to a 7-segment light emitting diode display 25, light emitting diode 7 and buzzer 43 for informing the user of the operating state of the washing machine.

マイクロコンピュータ４０は電源スイッチ５が押されて電源が投入されると起動し、図６及び図７に示すような洗濯および乾燥の基本的な制御処理プログラムを実行する。以下のその制御フローを説明する。 The microcomputer 40 is activated when the power switch 5 is pushed and the power is turned on, and executes a basic control processing program for washing and drying as shown in FIGS. The control flow is described below.

≪ステップＳ１０１≫
洗濯乾燥機の状態確認および初期設定を行う。 <<Step S101>>
Check the status of the washer/dryer and make initial settings.

≪ステップＳ１０２≫
操作パネル８の表示器７を点灯表示し、操作ボタンスイッチ６からの指示入力に従って洗濯コースを設定する。指示入力がない状態では、標準の洗濯コースまたは前回実施の洗濯コースを自動的に設定する。 <<Step S102>>
The indicator 7 of the operation panel 8 is turned on, and the washing course is set according to the instruction input from the operation button switch 6. - 特許庁When there is no instruction input, the standard washing course or the last washing course is automatically set.

≪ステップＳ１０３≫
操作パネル８の操作ボタンスイッチ６におけるスタートスイッチ６ａからの指示入力を監視して処理を分岐する。 <<Step S103>>
An instruction input from the start switch 6a on the operation button switch 6 of the operation panel 8 is monitored to branch the processing.

≪ステップＳ１０４≫
洗剤量検出処理を実行する。この洗剤量検出は、洗い水を給水する前の乾布状態において、洗濯槽９を静止させた状態で回転翼１１を一方向に回転させたときに、回転翼１１に作用する回転負荷量に基づいて衣類の布量を検出するように、駆動機構における洗濯脱水駆動電動機１３と電磁操作クラッチ機構１２を制御し、検出した布量に基づいて洗剤の適量（洗剤量）を求めることによって行う。 <<Step S104>>
Execute the detergent amount detection process. This amount of detergent is detected based on the rotational load acting on the rotor blade 11 when the rotor blade 11 is rotated in one direction while the washing tub 9 is stationary in the dry cloth state before the washing water is supplied. By controlling the washing/drying drive motor 13 and the electromagnetic operation clutch mechanism 12 in the drive mechanism so as to detect the amount of laundry, and determining the appropriate amount of detergent (detergent amount) based on the detected amount of laundry.

洗剤量は、予め設定した布量と洗剤量の対照テーブルを参照することによって求める。具体的には、布量の検出は、洗濯脱水駆動電動機１３としてインバータ駆動電動機を使用した構成では、洗濯脱水駆動電動機１３を回転させるように所定時間給電した時の到達回転速度を検出することによって行う。洗濯脱水駆動電動機１３としてコンデンサ分相単相誘導電動機を使用した構成では、洗濯脱水駆動電動機１３を飽和回転速度まで上昇させるように給電した状態で断電した後の惰性回転減速特性を検出することによって行う。そして、好ましい洗剤量は、予め設定した布量と洗剤量の対照テーブルを参照することによって求める。 The amount of detergent is obtained by referring to a preset comparison table of the amount of cloth and the amount of detergent. Specifically, in the configuration in which an inverter-driven motor is used as the washing/dehydrating motor 13, the amount of laundry is detected by detecting the rotational speed reached when power is supplied for a predetermined time so as to rotate the washing/dehydrating motor 13. conduct. In a configuration in which a capacitor split-phase single-phase induction motor is used as the washing/dehydration driving motor 13, the inertial rotation deceleration characteristic after power failure is detected in a state in which power is supplied so as to increase the washing/dehydration driving motor 13 to a saturated rotation speed. by Then, the desired amount of detergent is obtained by referring to a preset comparison table of the amount of cloth and the amount of detergent.

洗濯水量は、布量が所定の布量の範囲（適量）内のときには回転翼１１を越えない水位を維持して外槽１０の底部に溜まるように洗濯水量を設定する。また、この検出結果（布量）に基づいて洗濯時間を求めて設定する。布量検出が行われない時には、標準の洗濯時間を設定する。 The amount of washing water is set so that when the amount of laundry is within a predetermined range (appropriate amount) of the amount of laundry, the water level is maintained so as not to exceed the rotor blade 11 and the amount of washing water accumulates at the bottom of the outer tub 10.例文帳に追加Also, the washing time is obtained and set based on the detection result (cloth amount). When the amount of laundry is not detected, a standard wash time is set.

≪ステップＳ１０５≫
求めた洗剤量を操作パネル８の表示器２５に表示する。 <<Step S105>>
The determined amount of detergent is displayed on the display 25 of the operation panel 8 .

≪ステップＳ１０６≫
洗剤給水電磁弁を開き、洗剤・柔軟仕上げ剤容器２８の洗剤投入室に洗剤給水を実行する。使用者は、表示された量の粉末洗剤を洗剤・柔軟仕上げ剤容器２８洗剤投入室に投入した後、外蓋３を閉じるように操作する。洗剤給水が流れている洗剤投入室に投入された粉末洗剤は、洗剤給水の水と共に洗剤・柔軟仕上げ剤入口２８ａを通り外槽１０の底部に落下する。 <<Step S106>>
The detergent supply electromagnetic valve is opened to supply detergent to the detergent input chamber of the detergent/softener container 28 . The user puts the displayed amount of powdered detergent into the detergent/softener container 28 into the detergent-filling chamber, and then closes the outer lid 3 . The powdered detergent put into the detergent-filling chamber where the detergent water supply flows, drops to the bottom of the outer tub 10 through the detergent/softener inlet 28a together with the detergent water supply.

≪ステップＳ１０７≫
洗剤溶かし水位まで給水したら給水を停止する。洗剤溶かし水位とは、この後の洗剤溶かし工程（ステップＳ１０８）で洗濯槽９を回転させたときに、洗濯槽９の底で給水した水と洗剤を攪拌するのに十分な水量で、かつ水面が回転翼１１の下面の高さより低くなる（衣類が洗剤溶かし前に濡れない）ように設定したものである。 <<Step S107>>
Stop the water supply when the detergent reaches the water level. The detergent dissolving water level is a sufficient amount of water to stir the water supplied at the bottom of the washing tub 9 and the detergent when the washing tub 9 is rotated in the subsequent detergent dissolving step (step S108), and the water surface. is lower than the height of the lower surface of the rotor blade 11 (the clothes do not get wet before the detergent is dissolved).

≪ステップＳ１０８≫
洗濯槽９と回転翼１１を一体的に一方向に緩速回転させることによって、該洗濯槽９の底面で外槽１０の底部に投入された洗剤溶かし水と粉末洗剤を攪拌して、高洗剤濃度の洗い水を生成する洗剤溶かしを実行する。 <<Step S108>>
By slowly rotating the washing tub 9 and the rotor 11 integrally in one direction, the detergent-dissolved water and the powdered detergent put into the bottom of the outer tub 10 are stirred at the bottom of the washing tub 9 to produce a high detergent content. Detergent dissolution is performed to produce a concentrated wash water.

≪ステップＳ１０９≫
前洗いを実行する。この前洗いは、洗濯槽９を静止させた状態で回転翼１１を正逆回転させる撹拌を間欠的に行ない、回転翼１１の正逆回転中に循環ポンプ１６を運転することによって外槽１０の底部の洗い水をノズル３４から衣類上に降り掛ける。このとき、高濃度の洗い水が衣類に散布されるため、洗剤の浸透作用で衣類にむらなく浸透する。衣類に浸透した高濃度の洗い水は、油の溶解能力が高く、皮脂汚れなどの油脂汚れを溶解し、衣類から汚れが浮き上がらせる効果が非常に大きく、高い洗浄力が得られる。次に、回転翼１１と循環ポンプ１６の停止期間中に、水位センサ２１の検出信号を参照しながら洗剤給水電磁弁および洗濯給水電磁弁を開いて、水位が設定水位を越えないように補給水する。この運転を複数回繰り返すことによって、衣類を洗い水に馴染ませて回転翼１１上に分散させるように行なう。 <<Step S109>>
Carry out a pre-wash. In this pre-washing, the outer tub 10 is washed by intermittently stirring the rotating blades 11 forward and backward while the washing tub 9 is stationary, and operating the circulation pump 16 during the forward and reverse rotation of the rotating blades 11. Washing water from the bottom is sprinkled on the clothes from nozzles 34. - 特許庁At this time, since the washing water of high concentration is sprayed on the clothes, it permeates the clothes evenly due to the penetrating action of the detergent. The high-concentration washing water that permeates the clothes has a high ability to dissolve oil, dissolves oil stains such as sebum stains, and has a very large effect of lifting the stains from the clothes, resulting in a high detergency. Next, while the rotary blades 11 and the circulation pump 16 are stopped, the detergent water supply electromagnetic valve and the washing water supply electromagnetic valve are opened while referring to the detection signal of the water level sensor 21, and make-up water is supplied so that the water level does not exceed the set water level. do. By repeating this operation several times, the clothes are soaked in the washing water and dispersed on the rotary blade 11. - 特許庁

≪ステップＳ１１０≫
本洗いを実行する。この本洗いでは、先ず、前述と同様な方法で布量検出を行なって、設定されている洗濯時間を補正して設定する。その後に、洗濯槽９を静止させた状態で回転翼１１を正逆回転させながら循環ポンプ１６を運転して、外槽１０の底部に溜った洗い水をノズル３４から衣類に降り掛ける洗い水循環を行なう撹拌と、循環ポンプ１６の運転を停止して洗い水の循環を止めた状態で回転翼１１を正逆回転させる布ほぐし撹拌を繰り返す。回転翼１１の正逆回転により、衣類は洗濯槽９内で円周方向および半径方向に入れ替わり、満遍なく洗浄される。最後に、循環ポンプ１６の運転を停止して洗い水の循環を止めた状態で、回転翼１１を正逆回転させる均一化撹拌を実行して本洗い時間を終了させるようにする。 <<Step S110>>
Execute the main wash. In this main washing, first, the amount of laundry is detected in the same manner as described above, and the set washing time is corrected and set. After that, the circulation pump 16 is operated while rotating the rotary blade 11 forward and backward while the washing tub 9 is stationary, and the washing water circulates by pouring the washing water accumulated in the bottom of the outer tub 10 onto the clothes from the nozzles 34. The agitation to be performed and the disentanglement agitation by rotating the rotary blade 11 forward and backward while stopping the operation of the circulation pump 16 and stopping the circulation of the wash water are repeated. Due to the forward and reverse rotation of the rotary blades 11, the clothes are alternately rotated in the circumferential direction and the radial direction in the washing tub 9, so that the clothes are evenly washed. Finally, in a state in which the operation of the circulation pump 16 is stopped to stop the circulation of the washing water, the rotor blades 11 are rotated in forward and reverse directions to carry out homogenization stirring to end the main washing time.

≪ステップＳ１１１≫
第１回目の溜めすすぎを実行する。この溜めすすぎでは、先ず、排水弁１５を開いて外槽１０の底部に溜っている洗い水を排水した後に、洗濯槽９と回転翼１１を一体的に一方向に回転させて衣類に含まれている洗い水を遠心脱水する。この洗い水脱水時の洗濯槽９と回転翼１１の回転速度は、後述する最終脱水における回転速度（約１０００ｒ/ｍｉｎ）と同様に設定し、高い脱水率を実現するように脱水運転を行なう。 <<Step S111>>
Perform the first reservoir rinse. In this water rinsing, first, after opening the drain valve 15 and draining the washing water accumulated in the bottom of the outer tub 10, the washing tub 9 and the rotary blade 11 are integrally rotated in one direction to remove the water contained in the clothes. Centrifugally dehydrate the wash water. The rotational speeds of the washing tub 9 and rotor blades 11 during this wash water dehydration are set to be the same as the rotational speed (approximately 1000 r/min) in the final dehydration described later, and the dehydration operation is performed so as to achieve a high dehydration rate.

その後、排水電磁弁１５を閉じて洗濯槽９と回転翼１１を一体的に一方向に緩速回転させながら、洗濯給水電磁弁を開放して水道水を散水口から回転翼１１上の衣類に降り掛けるように給水する。 After that, while the drain solenoid valve 15 is closed and the washing tub 9 and the rotor blade 11 are slowly rotated integrally in one direction, the washing water supply solenoid valve is opened to pour tap water onto the clothes on the rotor blade 11 from the sprinkling port. Water the water so that it is dripping down.

次に、洗濯槽９と回転翼１１の回転を停止した状態で、外槽１０の底部の水位が設定水位を越えないようにすすぎ水給水を行なう。 Next, while the rotation of the washing tub 9 and the rotor blades 11 is stopped, rinse water is supplied so that the water level at the bottom of the outer tub 10 does not exceed the set water level.

次に、本洗いにおける押し洗い撹拌と同様に、洗濯槽９を静止させた状態で回転翼１１を正逆回転させながら、循環ポンプ１６を運転して外槽１０の底部に溜ったすすぎ水をノズル３４から回転翼１１上の衣類に降り掛けるように循環させる、すすぎ水循環撹拌すすぎを実行する。 Next, while rotating the rotor 11 forward and backward with the washing tub 9 stationary, the circulation pump 16 is operated to remove the rinse water accumulated at the bottom of the outer tub 10, in the same manner as the push washing agitation in the main washing. Rinse water circulation agitation rinsing is performed by circulating from the nozzle 34 so as to fall on the clothes on the rotary blade 11 .

次に、回転翼１１の回転と循環ポンプ１６の運転を停止した状態で、外槽１０の底部に溜るすすぎ水の水位を検出しながら、水位が設定水位を越えないように補給水を行なう。 Next, while the rotation of the rotor blades 11 and the operation of the circulation pump 16 are stopped, the water level of the rinsing water accumulated in the bottom of the outer tub 10 is detected, and replenishment water is supplied so that the water level does not exceed the set water level.

次に洗濯槽９を静止させた状態で回転翼１１を正逆回転させながら、循環ポンプ１６を運転して、外槽１０の底部に溜ったすすぎ水をノズル３４から回転翼１１上の衣類に降り掛けるように循環させる、すすぎ水循環撹拌すすぎを実行する。洗い時と同様、洗濯槽９内の衣類は円周方向と半径方向に入れ替わるので、すすぎ水が衣類に満遍なくかかり、洗剤分が希釈される。 Next, while the rotary blades 11 are rotated forward and backward while the washing tub 9 is stationary, the circulation pump 16 is operated, and the rinse water collected at the bottom of the outer tub 10 is discharged from the nozzles 34 onto the clothes on the rotary blades 11. Perform a rinse water circulating agitated rinse with drenching circulation. As in washing, the clothes in the washing tub 9 are exchanged in the circumferential direction and the radial direction, so that the rinsing water is evenly applied to the clothes, diluting the detergent.

その後、循環ポンプ１６を停止してすすぎ水の循環を止めた状態で、回転翼１１の正逆回転を継続する均一化撹拌を行なう。 Thereafter, the circulation pump 16 is stopped to stop the circulation of the rinsing water, and uniform stirring is performed by continuing the forward and reverse rotation of the rotor blades 11 .

≪ステップＳ１１２≫
第２回目の溜めすすぎを実行する。この第２回目の溜め濯ぎは、柔軟仕上げ剤給水電磁弁を開いて洗剤・柔軟剤投入容器２８における柔軟仕上げ剤投入室に給水することによって、該柔軟仕上げ剤投入室内の柔軟仕上げ剤を外槽１０の底部に導入する制御を付加する。それ以外の動作は、第１回目の溜め濯ぎと同様に行なう。 <<Step S112>>
Perform a second reservoir rinse. This second rinsing is performed by opening the softener water supply solenoid valve and supplying water to the softener charging chamber in the detergent/softener charging container 28, thereby removing the softener from the softener charging chamber into the outer tank. Add a control that introduces at the bottom of 10. Other operations are performed in the same manner as the first rinsing.

≪ステップＳ１１３≫
最終脱水処理を実行する。最終脱水は、排水電磁弁１５を開放としたままの状態で、洗濯槽９と回転翼１１を一体的にして、一方向に約１０００ｒ/ｍｉｎの高速回転させるように駆動機構を運転して、洗濯槽９内の衣類を遠心脱水するように行う。この最終脱水の運転時間は、所望の脱水率が得られる時間に設定する。 <<Step S113>>
Execute the final dehydration process. In the final dehydration, the washing tub 9 and the rotary blade 11 are integrated with the drain electromagnetic valve 15 left open, and the driving mechanism is operated so as to rotate at a high speed of about 1000 r/min in one direction. The clothes in the washing tub 9 are centrifugally dehydrated. The operation time for this final dehydration is set to a time at which a desired dehydration rate is obtained.

≪ステップＳ１１４≫
洗濯乾燥コースが設定されているかどうかを確認して、処理を分岐する。 <<Step S114>>
Check whether the washing/drying course is set and branch the process.

≪ステップＳ１１５≫
洗濯乾燥コースが設定されている場合は、乾燥を実行する。この乾燥は、排水電磁弁１５を開放したままの状態として、洗濯工程と同様に、洗濯槽９を静止させた状態で回転翼１１を正逆回転させながら、乾燥ダクト２２の途中に設けた送風ファン１９を運転することによって、外槽１０内の空気を通水通気口１０ｂから乾燥ダクト２２内に吸い出し、この乾燥ダクト２２内を通過するときに該乾燥ダクト２２内に設置した除湿機構２２ｂから流れ落ちる冷却水に触れさせて、冷却除湿した後にリントフィルタを通して糸屑を捕集し、ヒータ２０によって加熱した後に温風吹出し口５４または、温風吹出し口５６から洗濯槽９内に吹き込むことにより行う。乾燥は、温度センサ２６により温風の温度を監視しながら実行し、温度変化の割合が所定の値になったときに終了する。 <<Step S115>>
If the washing/drying course is set, the drying is performed. This drying is carried out by keeping the drain solenoid valve 15 open and rotating the rotor 11 forward and backward while keeping the washing tub 9 stationary in the same manner as in the washing process. By operating the fan 19, the air in the outer tank 10 is sucked out from the water passage vent 10b into the drying duct 22, and when passing through the drying duct 22, the air is discharged from the dehumidifying mechanism 22b installed in the drying duct 22. After contacting the falling cooling water to cool and dehumidify, lint waste is collected through a lint filter, heated by a heater 20, and then blown into the washing tub 9 from a hot air outlet 54 or a hot air outlet 56. - 特許庁. Drying is performed while monitoring the temperature of the warm air by the temperature sensor 26, and is completed when the rate of temperature change reaches a predetermined value.

このような構成を備えた縦型洗濯乾燥機において、次に本発明の特徴的な構成とその動作を説明する。図８は洗濯槽９の上面から温風５１を吹き出す構成を示す縦断面図、図９は洗濯槽９の測面から温風５２を吹き出す構成を示す縦断面図、図１０及び図１１は図８～図９に示した実施例における、マイクロコンピュータが実行する制御処理の一例を示す制御フローを示したフローチャートである。 In the vertical washing/drying machine having such a configuration, the characteristic configuration and operation of the present invention will now be described. 8 is a longitudinal sectional view showing a configuration for blowing hot air 51 from the upper surface of the washing tub 9, FIG. 9 is a longitudinal sectional view showing a configuration for blowing hot air 52 from the side surface of the washing tub 9, and FIGS. FIG. 10 is a flowchart showing a control flow showing an example of control processing executed by a microcomputer in the embodiment shown in FIGS. 8 to 9; FIG.

以下、乾燥工程の詳細な制御フローを説明する。尚、図１０のステップＳ１０1からステップＳ１１４までは、図５及び図６に示した制御フローと同等であるので説明を省略する。 A detailed control flow of the drying process will be described below. Note that steps S101 to S114 in FIG. 10 are the same as those in the control flow shown in FIGS. 5 and 6, so description thereof will be omitted.

図１０において、ステップＳ１１４で洗濯乾燥コースが選ばれていない場合はこの制御フローは洗濯完了となって終了される。一方、洗濯乾燥コースが選ばれている場合は以下のステップを実行する。 In FIG. 10, if the washing/drying course is not selected in step S114, this control flow ends as washing is completed. On the other hand, when the washing/drying course is selected, the following steps are executed.

≪ステップＳ２００≫
乾燥工程では、更に衣類の脱水を行うために高速で洗濯槽９を回転させる。尚、先の洗濯工程で充分な脱水が行われている場合はこのステップを省略することができる。 <<Step S200>>
In the drying process, the washing tub 9 is rotated at high speed to dehydrate the clothes. This step can be omitted if sufficient dehydration has been carried out in the previous washing process.

≪ステップＳ２０１≫
ステップＳ２００を所定時間行うための処理であり、決められた規定時間を経過するまで脱水工程を実行する。このステップも先の洗濯工程で充分な脱水が行われている場合は、省略することができる。 <<Step S201>>
This is a process for performing step S200 for a predetermined period of time, and the dehydration process is performed until a predetermined period of time elapses. This step can also be omitted if sufficient dehydration has been carried out in the previous washing process.

≪ステップＳ２０４≫
図８に示す流路切替え部５３に内蔵された切替え弁５３ｂを作動させて、ヒータ２０によって加熱された送風ファン１９からの空気を温風吹出し口５４に導き、外槽１０の上部から衣類の上面に向けて温風５１を吹付ける。 <<Step S204>>
The switching valve 53b built in the flow path switching unit 53 shown in FIG. Hot air 51 is blown toward the upper surface.

≪ステップＳ２０５≫
洗濯槽９、または回転翼１１を回転させることにより衣類全体を撹拌しながら加熱させ乾燥を行う。 <<Step S205>>
By rotating the washing tub 9 or the rotary blade 11, the entire clothes are heated and dried while being agitated.

≪ステップＳ２０６≫
ステップＳ２０５を所定時間行うための処理であり、決められた規定時間を経過するまで温風５１を吹付けながら洗濯槽９、または回転翼１１を回転させる。 <<Step S206>>
This is a process for performing step S205 for a predetermined period of time, in which the washing tub 9 or the rotor blade 11 is rotated while blowing the hot air 51 until a predetermined period of time elapses.

≪ステップＳ２０７≫
洗濯槽の回転を停止させて、温風吹き出し口５６と温風吹き出し孔５７とが対向した位置で静止させる。 <<Step S207>>
The rotation of the washing tub is stopped, and the hot air outlet 56 and the hot air outlet 57 are made to stand still.

≪ステップＳ２０８≫
図９に示す流路切替え部５３に内蔵された切替え弁５３ｂを作動させて、ヒータ２０によって加熱された送風ファン１９からの温風が風路５５に導かれる。風路５５に導かれた温風５２は、温風吹出し口５６から底板９ｄに設けられた温風吹出し孔５７に繋がる風路で斜め上方向に曲げられ衣類へ吹付けられる。斜め上方向の温風を吹付けられた衣類は、持ち上げられながら洗濯槽９の底部から上方の衣類のない空間に押し広げられることにより広がり易くなり、乾燥中に発生するしわが低減する。また、回転翼１１を回転させると回転翼のなだらかな傾斜面１１ｈにより衣類が持ち上げられる。持ち上げられた衣類に高速の温風５２が吹付けられることにより、衣類が押し広げられ、乾燥中に発生するしわが低減する。また、吹出された高速の温風５２を集中して個々の衣類に吹付けることにより、温風５２を分散させる従来例と比較して衣類に当たる風速、風量が大きくなるため、より衣類が押し広げられ乾燥中に発生するしわが低減される。また、衣類からの蒸発が促進されて乾燥効率が向上するため、乾燥時の消費電力量を低減することが出来る。なお、外槽１０に設けられた温風吹出し口５６の面積は、風路抵抗を低減するために、洗濯槽９の貫通孔９ａの直径約５ｍｍや回転翼１１の貫通孔１１ｃの直径約３ｍｍより大きい。また、風量が１.２ｍ３/ｍｉｎの場合、衣類を押し広げる効果が出る風速５０ｍ/ｓ以上とするには温風吹出し口５６の面積は４００ｍｍ２となる。さらに、衣類を押し広げる効果を大きくするために風速８０ｍ/ｓ以上とするには温風吹出し口５６の面積は２５０ｍｍ２となる。 <<Step S208>>
The switching valve 53b built in the flow path switching portion 53 shown in FIG. The warm air 52 guided to the air passage 55 is bent obliquely upward in the air passage leading from the hot air outlet 56 to the warm air outlet 57 provided in the bottom plate 9d and blown onto the clothes. The clothes blown with hot air obliquely upward are pushed out from the bottom part of the washing tub 9 to an upper space free from the clothes while being lifted, so that the clothes are easily spread, and wrinkles generated during drying are reduced. Further, when the rotary blade 11 is rotated, the clothes are lifted by the gently inclined surface 11h of the rotary blade. The high-speed warm air 52 blows onto the lifted clothes to spread the clothes and reduce wrinkles that occur during drying. In addition, by concentrating the blown high-speed hot air 52 and blowing it on each clothing, the air speed and air volume hitting the clothing are increased compared to the conventional example in which the hot air 52 is dispersed, so that the clothing is further spread. wrinkles generated during drying are reduced. In addition, since the evaporation from the clothes is accelerated and the drying efficiency is improved, the power consumption during drying can be reduced. The area of the hot air outlet 56 provided in the outer tub 10 is set to about 5 mm in diameter of the through hole 9a of the washing tub 9 and about 3 mm in diameter of the through hole 11c of the rotor blade 11 in order to reduce air resistance. greater than Further, when the air volume is 1.2 m 3 /min, the area of the warm air outlet 56 is 400 mm 2 in order to set the air velocity to 50 m/s or higher, which is effective in spreading the clothes. Furthermore, the area of the hot air outlet 56 is 250 mm 2 in order to increase the air velocity of 80 m/s or more in order to increase the effect of spreading the clothes.

一方、温風５２が通り抜ける温風吹出し孔５７の面積は、温風吹出し口５６の面積とほぼ同じか若干大きい面積として、温風吹出し口５６から流れる空気流が温風吹出し孔５７で閉塞されない様にしている。風路面積が４００ｍｍ２の場合、高さ１６ｍｍ、幅２５ｍｍの長方形形状または、直径２２.６ｍｍの円形となっている。同様に風路面積が２５０ｍｍ２の場合は、高さ１０ｍｍ、幅２５ｍｍの長方形形状または、直径１７.８ｍｍの円形となる。なお、温風吹出し孔５７の両側には衣類のボタンなどの引っ掛かりや噛込みなどを防止するために、表面が滑らかなスロープ５７ａが設けられている。 On the other hand, the area of the hot air blowing holes 57 through which the hot air 52 passes is set to be substantially the same as or slightly larger than the area of the hot air blowing holes 56 so that the air flow flowing from the hot air blowing holes 56 is not blocked by the hot air blowing holes 57. like When the air passage area is 400 mm 2 , it has a rectangular shape with a height of 16 mm and a width of 25 mm, or a circular shape with a diameter of 22.6 mm. Similarly, when the air passage area is 250 mm 2 , the shape is a rectangle with a height of 10 mm and a width of 25 mm, or a circle with a diameter of 17.8 mm. On both sides of the hot air blowing hole 57, slopes 57a having a smooth surface are provided in order to prevent clothes buttons from being caught or caught.

なお、ステップ２０４からステップ２０８の工程において、図１２に示す流路切替え部５３に内蔵された切替え弁５３ｂを略中間の位置にして、ヒータ２０によって加熱された送風ファン１９からの温風を分けて、温風吹出し口５４と温風吹出し口５６の両方から同時に衣類に吹付ける工程を実施しても良い。これにより、衣類全体を加熱し易くなり乾燥効率が向上する。 In the processes from step 204 to step 208, the switching valve 53b incorporated in the flow path switching section 53 shown in FIG. Alternatively, a step of simultaneously blowing hot air from both the hot air outlet 54 and the warm air outlet 56 onto the clothes may be performed. As a result, the entire clothes can be easily heated, and the drying efficiency is improved.

≪ステップＳ２０９≫
温度センサ２６により温風の温度を監視しながら実行し、温度変化の割合が所定の値になったときに乾燥終了と判断する。衣類が乾燥していない場合は、ステップＳ２０８の温風５２の吹付けと、回転翼１１を回転させて再度ステップＳ２０９の判断を行う。 <<Step S209>>
The temperature sensor 26 monitors the temperature of the hot air, and it is determined that the drying is completed when the rate of temperature change reaches a predetermined value. If the clothes are not dry, the hot air 52 is blown in step S208, the rotor blade 11 is rotated, and the determination in step S209 is performed again.

≪ステップＳ２１０≫
ヒータ２０をＯＦＦにした後、更にファン１９をＯＦＦにし、回転翼１１の回転を停止させて乾燥工程を終了する。 <<Step S210>>
After the heater 20 is turned off, the fan 19 is also turned off to stop the rotation of the rotor blades 11, thus ending the drying process.

以上、温風を斜め上方向に吹出すことにより、底部の衣類を持ち上げながら衣類のない空間に押し広げたり、また、回転翼で持ち上げられた衣類に温風を集中して個々の衣類に吹付けたりすることにより、衣類が押し広げられ乾燥中に発生するしわが低減される。また、衣類からの蒸発が促進されて乾燥効率が向上するため、乾燥時の消費電力量を低減することが出来る。なお、本実施の形態例では熱源としてヒータ２０を用いて説明したが、熱源はヒートポンプによるものでも同様の効果を得ることが出来る。 As described above, by blowing hot air obliquely upward, it is possible to lift the clothes on the bottom and push them into a space without clothes, or to concentrate the hot air on the clothes lifted by the rotary blades and blow them to individual clothes. By applying it, the clothes are spread out and wrinkles generated during drying are reduced. In addition, since the evaporation from the clothes is accelerated and the drying efficiency is improved, the power consumption during drying can be reduced. Although the heater 20 is used as the heat source in this embodiment, the same effect can be obtained by using a heat pump as the heat source.

さらに、本実施例の乾燥工程では、まず外槽１０の上部にある温風吹出し口５４から洗濯槽９内へ大風量の温風を吹付けて満遍なく衣類の温度を上昇させた後、外槽１０の側部にある温風吹出し口５６から局所的に強い温風を吹付けて衣類のしわを伸ばすことが可能となる。このとき、温風吹出し口５４から温風吹出し口５６へ送風先を切り替えることで、送風ファン１９の回転速度の過度な上昇を抑えつつ、風速を高めることが可能である。 Furthermore, in the drying process of this embodiment, first, a large amount of warm air is blown from the hot air outlet 54 in the upper part of the outer tub 10 into the washing tub 9 to evenly raise the temperature of the clothes, and then the outer tub is dried. It is possible to locally blow strong warm air from the hot air outlet 56 on the side of 10 to smooth out the wrinkles of the clothes. At this time, by switching the blowing destination from the warm air outlet 54 to the warm air outlet 56, it is possible to increase the wind speed while suppressing an excessive increase in the rotational speed of the blower fan 19.

＜実施例２＞
次に、第２の実施例について、図１３を用いて説明する。図１３は洗濯槽の底部から温風を吹き出す構成を示す縦断面図である。第１の実施の形態と共通する構成については重複する説明を省略する。 <Example 2>
A second embodiment will now be described with reference to FIG. FIG. 13 is a longitudinal sectional view showing a configuration for blowing hot air from the bottom of the washing tub. Duplicate description of the configuration common to the first embodiment will be omitted.

第１の実施例と異なる点は、底板９ｄに設けられた温風吹出し孔５７に繋がる風路の曲りを小さくして、より斜め上方向に温風５２を吹付ける温風吹出し孔５７ｂを追加したことである。図１１に示す乾燥工程Ｓ２０７において、洗濯槽９の回転を停止させて、温風吹き出し口５６と温風吹き出し孔とが対向した位置で静止させる。この時、衣類の量が多い場合は温風吹出し孔に繋がる風路の曲りが小さい温風吹出し孔５７ｂと組合せる。乾燥工程Ｓ２０８において、図１３に示す流路切替え部５３に内蔵された切替え弁５３ｂを作動させて、ヒータ２０によって加熱された送風ファン１９からの温風が風路５５に導かれる。風路５５に導かれた温風５２は、温風吹出し口５６から底板９ｄに設けられた温風吹出し孔５７ｂを通り、温風吹出し孔５７に対してより斜め上方向に吹出し、衣類に吹付けられる。衣類の量が多く、底板９ｄから衣類のない空間までの距離が長くなると通風抵抗が大きくなり衣類を押し広げる力が低下する。一方、温風５２の吹出し方向を垂直方向に近づけて底板９ｄから衣類のない空間までの距離を短くし、通風抵抗を小さくすることにより、衣類を押し広げる力が増加し、乾燥中に発生するしわが低減する。このように衣類の量によって温風５２の吹出し方向を変えることにより衣類を押し広げる力の低下を防止することができる。また、回転翼１１を回転させると回転翼１１のなだらかな傾斜面１１ｈにより衣類が持ち上げられる。持ち上げられた衣類に斜め下から温風５２が吹付けられることにより、衣類に加わる重力と相まって衣類が押し広げられ、乾燥中に発生するしわが低減する。また、吹出された温風５２を集中して個々の衣類に吹付けることにより、温風５２を分散させる従来例と比較して衣類に当たる風速、風量が大きくなるため、より衣類が押し広げられ乾燥中に発生するしわが低減される。また、衣類からの蒸発が促進されて乾燥効率が向上するため、乾燥時の消費電力量を低減することが出来る。さらに、外槽１０の上部にある温風吹出し口５４からも同時に温風を吹付けるようにすれば、回転翼１１による回転と温風吹出し孔５７ｂからの送風で衣類が効果的に舞い上がり、この舞い上がった衣類に対して、温風吹出し口５４から温風が吹付けられるので、しわ低減や乾燥促進の効果が高まる。 The difference from the first embodiment is that the curvature of the air path leading to the hot air blowing holes 57 provided in the bottom plate 9d is reduced, and the hot air blowing holes 57b for blowing the warm air 52 obliquely upward are added. It is what I did. In the drying step S207 shown in FIG. 11, the rotation of the washing tub 9 is stopped, and the warm air outlet 56 and the hot air outlet are made to stand still at a position facing each other. At this time, when the amount of clothes is large, the hot air blowing hole 57b is combined with the warm air blowing hole 57b having a small curvature of the air path connected to the warm air blowing hole. In the drying step S208, the switching valve 53b incorporated in the flow path switching portion 53 shown in FIG. The hot air 52 guided to the air path 55 passes through the hot air blowing holes 57b provided in the bottom plate 9d from the hot air blowing port 56, and is blown diagonally upward with respect to the hot air blowing holes 57, and is blown onto the clothes. Attached. When the amount of clothes is large and the distance from the bottom plate 9d to the space without clothes is long, the ventilation resistance increases and the force to spread the clothes is reduced. On the other hand, by making the blowing direction of the hot air 52 closer to the vertical direction to shorten the distance from the bottom plate 9d to the space where there is no clothes, and to reduce the airflow resistance, the force to spread the clothes is increased, which is generated during drying. Wrinkles are reduced. By changing the blowing direction of the warm air 52 according to the amount of clothes in this way, it is possible to prevent a decrease in the force for spreading the clothes. Also, when the rotary blade 11 is rotated, the clothing is lifted by the gently inclined surface 11h of the rotary blade 11. - 特許庁The warm air 52 is blown obliquely downward on the lifted clothes, and the clothes are spread out together with the gravity acting on the clothes, thereby reducing wrinkles generated during drying. In addition, by concentrating the blown hot air 52 and blowing it onto individual clothes, the speed and volume of the air hitting the clothes are increased compared to the conventional example in which the hot air 52 is dispersed, so the clothes are further spread and dried. Wrinkles occurring inside are reduced. In addition, since the evaporation from the clothes is accelerated and the drying efficiency is improved, the power consumption during drying can be reduced. Furthermore, if hot air is blown simultaneously from the hot air outlet 54 in the upper part of the outer tub 10, the rotation of the rotary blade 11 and the air from the hot air outlet 57b effectively lift the clothes. Since hot air is blown from the hot air outlet 54 to the clothes that have been lifted up, the effect of reducing wrinkles and promoting drying is enhanced.

なお、温風５２の吹出し方向の変更は乾燥工程の経過時間によって変えても良い。乾燥が進むと衣類の重さが軽くなって衣類が動きやすくなり、通風抵抗が小さくなるため、温風５２の吹出し方向を水平に近づけても衣類を押し広げ易くなる。温風５２の吹出し方向を定期的に変えることによって満遍なく衣類を押し広げることにより、さらに、乾燥中に発生するしわが低減される。また、衣類からの蒸発が促進されて乾燥効率が向上するため、乾燥時の消費電力量を低減することが出来る。 The blowing direction of the hot air 52 may be changed according to the elapsed time of the drying process. As the drying progresses, the weight of the clothes becomes lighter, the clothes become easier to move, and the ventilation resistance becomes smaller. Spreading the clothes evenly by periodically changing the blowing direction of the hot air 52 further reduces wrinkles generated during drying. In addition, since the evaporation from the clothes is accelerated and the drying efficiency is improved, the power consumption during drying can be reduced.
