また、水路部材５０は、取付部５２が形成される位置では、水路５０ｓが内方に突出して蛇行するように形成されている。したがって、水路部材５０の外周縁部は、ほぼ円となるように形成されている。このように、水路部材５０の外側に突出する部分を無くすことで、水路部材５０を外槽カバー９ａの外周縁部により近い側に配置することができ、洗濯兼脱水槽８と外槽９との隙間に対向する位置に水路部材５０を好適に配置することができる。 Further, the water channel member 50 is formed such that the water channel 50 s protrudes inwardly and meanders at a position where the attachment portion 52 is formed. Therefore, the outer peripheral edge of the water channel member 50 is formed to be substantially a circle. Thus, by eliminating the portion that protrudes outside the water channel member 50, the water channel member 50 can be disposed closer to the outer peripheral edge of the outer tub cover 9a, and the washing / dehydrating tub 8 and the outer tub 9 The water channel member 50 can be suitably arranged at a position facing the gap.
図６（ａ）に示すように、水路部材５０の内側面５０ｂには、２４個の側面側散水口５０ｂ１が周方向に間隔を置いて形成されている（一部のみ図示）。図６（ｂ）に示すように、水路部材５０の底面５０ａには、４個の底面側散水口５０ａ１が周方向に間隔を置いて形成されている。 As shown to Fig.6 (a), 24 side surface side sprinkling ports 50b1 are formed in the inner surface 50b of the water channel member 50 at intervals in the circumferential direction (only one part is shown).

The number of the bottom-side watering port 50a1 and the side surface-side watering port 50b1 is not limited to the number of the present embodiment, and can be appropriately increased or decreased according to the type of the washing / drying machine 1A and the internal structure.
図８に示すように、外槽カバー９ａの外周縁部の下面には、水路部材５０が収容され、下側が開放されている凹部９ａ１が周方向に沿って形成されている。また、凹部９ａ１の底面９ａ２には、２本の溝９ａ３、９ａ４が、水路部材５０の内側面５０ｂ、外側面５０ｃに対応する位置に形成されている。この溝９ａ３、９ａ４にシール部材（図示せず）を注入して、溝９ａ３、９ａ４に内側面５０ｂ、外側面５０ｃを突き合わせた状態において、取付部５１、５２を外槽カバー９ａにねじ固定することによって水路部材５０が外槽カバー９ａに対して水密に固定される。また、このとき、水路部材５０の側面側散水口５０ｂ１は、凹部９ａ１の側壁部９ａ５と対向している。 As shown in FIG. 8, the water channel member 50 is accommodated in the lower surface of the outer peripheral edge of the outer tub cover 9a, and a recess 9a1 is formed along the circumferential direction. In addition, two grooves 9a3 and 9a4 are formed on the bottom surface 9a2 of the recess 9a1 at positions corresponding to the inner side surface 50b and the outer side surface 50c of the water channel member 50. A seal member (not shown) is injected into the grooves 9a3 and 9a4, and the mounting portions 51 and 52 are screwed to the outer tank cover 9a in a state where the inner surface 50b and the outer surface 50c are abutted with the grooves 9a3 and 9a4. Thus, the water channel member 50 is fixed in a watertight manner to the outer tank cover 9a. Further, at this time, the side surface water spray port 50b1 of the water channel member 50 faces the side wall 9a5 of the recess 9a1.
このようにして水路部材５０を外槽カバー９ａに取り付けることで、本実施形態では、水路部材５０が、洗濯兼脱水槽８（バランスリング８ｃ）と外槽９との間の隙間Ｔに対応する位置に配置される。なお、本実施形態では、水路部材５０の底面５０ａ、内側面５０ｂおよび外側面５０ｃと、この水路部材５０の凹面が対向する外槽カバー９ａの底面９ａ２とで囲まれる空間が給水経路に相当する。 By attaching the water channel member 50 to the outer tub cover 9a in this way, in this embodiment, the water channel member 50 corresponds to the gap T between the washing and dewatering tub 8 (balance ring 8c) and the outer tub 9. Placed in position. In the present embodiment, a space surrounded by the bottom surface 50a, the inner side surface 50b, and the outer surface 50c of the water channel member 50 and the bottom surface 9a2 of the outer tub cover 9a facing the concave surface of the water channel member 50 corresponds to the water supply path. .
図９に示すように、洗濯乾燥機１Ａは、制御装置１００を備える。制御装置１００は、マイコン１１０を中心に構成される。マイコン１１０は、運転パターンデータベース１１１、工程制御部１１２、回転速度算出部１１３、衣類重量算出部１１４、槽洗浄水量算出部１１５などを備える。 As shown in FIG. 9, the washing / drying machine 1 </ b> A includes a control device 100. The control device 100 is configured around a microcomputer 110. The microcomputer 110 includes an operation pattern database 111, a process control unit 112, a rotation speed calculation unit 113, a clothing weight calculation unit 114, a tank washing water amount calculation unit 115, and the like.
マイコン１１０は、操作ボタン７ａから入力された運転コースにあった運転パターンを呼び出し、洗濯または／および乾燥を開始する機能を有する。 The microcomputer 110 has a function of calling an operation pattern corresponding to an operation course input from the operation button 7a and starting washing or / and drying.
工程制御部１１２は、運転パターンデータベース１１１から呼び出された運転パターンに基づき、洗い工程、すすぎ工程、脱水工程、槽洗浄工程、乾燥工程の各工程を運転制御する機能を有する。各工程において、工程制御部１１２は、それぞれ駆動回路を介して、給水ユニット１２Ａ（給水電磁弁１２ａ〜１２ｄ、切替電磁弁１２ｅ）、排水弁１４、モータ１０ａ、クラッチ機構１０ｂ、ヒータ２２、ファン２１、循環ポンプ１７を駆動制御する機能を有する。 The process control unit 112 has a function of controlling the operation of each of the washing process, the rinsing process, the dehydration process, the tank washing process, and the drying process based on the operation pattern called from the operation pattern database 111. In each process, the process control unit 112 includes a water supply unit 12A (water supply electromagnetic valves 12a to 12d, a switching electromagnetic valve 12e), a drain valve 14, a motor 10a, a clutch mechanism 10b, a heater 22, and a fan 21 via drive circuits. And has a function of driving and controlling the circulation pump 17.
回転速度算出部１１３は、モータ１０ａの回転を検出する回転検出装置２８からの検出値に基づき、モータ１０ａの回転速度を算出する機能を有する。 The rotation speed calculation unit 113 has a function of calculating the rotation speed of the motor 10a based on the detection value from the rotation detection device 28 that detects the rotation of the motor 10a.
衣類重量算出部１１４は、回転速度算出部１１３で算出された回転速度と、モータ電流検出装置２９の検出値に基づいて、洗濯兼脱水槽８内の衣類の重量を算出する機能を有する。衣類の重量が増加することにより洗濯兼脱水槽８を回転させるための負荷が大きくなり、モータ１０ａに流れるモータ電流が多く必要になることから、モータ１０ａのモータ電流と回転速度により衣類の重量を算出することができる。 The clothing weight calculation unit 114 has a function of calculating the weight of clothing in the washing and dewatering tub 8 based on the rotation speed calculated by the rotation speed calculation unit 113 and the detection value of the motor current detection device 29. Since the load for rotating the washing / dehydrating tub 8 is increased due to the increase in the weight of the clothes and a large motor current is required to flow through the motor 10a, the weight of the clothes is determined by the motor current and the rotation speed of the motor 10a. Can be calculated.
槽洗浄水量算出部１１５は、衣類重量算出部１１４で算出された衣類の重量または、水位検出装置３６の検出値に基づいて、槽洗浄水の供給量を算出する機能を有する。外槽９、洗濯兼脱水槽８、回転翼８ｂに付着する汚れのうち、汚れと結合した洗剤や洗剤の溶け残りなどの洗剤カス（石鹸カス）や水垢などは、比重が小さいため水面に集まりやすく、喫水線付近の壁面に付着または飛散する。なお、ここでは、外槽９の内周面９ｓや洗濯兼脱水槽８の外周面８ｓの水面、つまり水と期槽の境界線を喫水線とする。喫水線より上側はすすぎ水が流れにくいことから、洗剤カスや水垢は外槽９および洗濯兼脱水槽８の喫水線付近に堆積しやすい。そのため、喫水線付近に多量の水を流すことで、汚れが付着して堆積するのを抑制できる。詳細は後述するが、槽洗浄水は、外槽９上部の水路部材５０の底面側散水口５０ａ１と側面側散水口５０ｂ１から噴射される（図１２参照）。衣類の量が多いとき、洗い工程Ｓ１〜Ｓ８（図１１参照）やすすぎ工程Ｓ１６〜Ｓ１８（図１１参照）での水位は高くなり、喫水線の位置も外槽９および洗濯兼脱水槽８の上部になる。このため、喫水線と底面側散水口５０ａ１と底面側散水口５０ｂ１が近くなり、前記底面側散水口５０ａ１と底面側散水口５０ｂ１から噴射された槽洗浄水は、勢いを失わずに喫水線付近に到達する。よって、少ない槽洗浄水でも汚れを洗い流すことが可能となる。このように、本発明は、洗剤カスや水垢などの堆積が原因となる汚れの位置が、水位によって異なることに注目し、水位に応じて槽洗浄水量を最適化することで、使用水量の低減を図るものである。なお、水位は、衣類重量算出部１１４で算出された衣類の重量か、ユーザによる手動設定から求めることができ、または洗濯運転を一時停止してユーザが任意の水量を追加した場合でも水位検出装置３６で求めることができる。 The tank cleaning water amount calculation unit 115 has a function of calculating the supply amount of the tank cleaning water based on the weight of clothing calculated by the clothing weight calculation unit 114 or the detection value of the water level detection device 36. Of the dirt adhering to the outer tub 9, the washing / dehydrating tub 8, and the rotary blade 8b, detergent scum (soap scum) and scales such as detergents and undissolved detergent are collected on the surface of the water because of their low specific gravity. Easily attaches or scatters on the wall near the waterline. Here, the water surface of the inner peripheral surface 9 s of the outer tub 9 and the outer peripheral surface 8 s of the washing and dewatering tub 8, that is, the boundary line between water and the tank is referred to as a draft line. Since rinsing water does not flow easily above the water line, detergent waste and scale are likely to accumulate near the water line of the outer tub 9 and the washing and dewatering tub 8. Therefore, it is possible to prevent dirt from adhering and accumulating by flowing a large amount of water near the waterline. Although details will be described later, the tank washing water is sprayed from the bottom surface side sprinkling port 50a1 and the side surface side sprinkling port 50b1 of the water channel member 50 in the upper portion of the outer tub 9 (see FIG. 12). When the amount of clothing is large, the water level in the washing steps S1 to S8 (see FIG. 11) and the rinsing steps S16 to S18 (see FIG. 11) is high, and the position of the water line is also the upper part of the outer tub 9 and the washing and dehydrating tub 8. become. For this reason, the water line, the bottom surface side water spout 50a1 and the bottom surface side water spout 50b1 are close to each other, and the tank washing water sprayed from the bottom surface side water spout 50a1 and the bottom surface side water spout 50b1 reaches the vicinity of the water line without losing momentum. To do. Therefore, it is possible to wash away dirt with a small amount of tank washing water. As described above, the present invention pays attention to the fact that the position of dirt caused by accumulation of detergent residue and scale varies depending on the water level, and the amount of water used is reduced by optimizing the amount of tank washing water according to the water level. Is intended. The water level can be obtained from the weight of the clothing calculated by the clothing weight calculation unit 114 or manually set by the user, or even when the user adds an arbitrary amount of water after pausing the washing operation. 36.

When the finishing agent / tank washing water supply electromagnetic valve 12b and the switching electromagnetic valve 12e are opened, tap water is supplied into the outer tank 9 through the hose 12j, the charging device 11, and the charging hose 11a. Further, when the finishing agent / tank cleaning water supply electromagnetic valve 12b is opened, tap water is supplied to the water channel member 50 via the cleaning hose 11c. When the cooling water supply electromagnetic valve 12c is opened, tap water is supplied to a water cooling / dehumidifying mechanism (not shown) in the drying duct 20 via a hose (not shown).
図１１に示すように、布量センシング工程Ｓ１では、工程制御部１１２が洗濯兼脱水槽８を回転させ、衣類重量算出部１１４が注水前の衣類について布量を算出する。算出した布量は、脱水・槽洗浄シャワーＳ２３で使用する槽洗浄水の供給量を決定するために用いられる。 As shown in FIG. 11, in the cloth amount sensing step S <b> 1, the process control unit 112 rotates the washing / dehydrating tub 8, and the garment weight calculation unit 114 calculates the cloth amount for the garment before water injection.

給水・洗剤投入工程Ｓ２では、工程制御部１１２が外槽給水電磁弁１２ｄを開弁し、水道水を注水ホース１１ｂを介して外槽９と洗濯兼脱水槽８の間から外槽９内に注水する。また、工程制御部１１２は、外槽給水電磁弁１２ｄが開弁されてから所定時間経過後に閉弁する。これは、給水ホース接続口４に接続されている注水ホース１１ｂ内に空気が含まれていることがあり、その空気を外槽９内に排出する動作である。 In the water supply / detergent charging step S2, the process control unit 112 opens the outer tank water supply electromagnetic valve 12d, and tap water enters the outer tank 9 from between the outer tank 9 and the washing / dehydrating tank 8 via the water injection hose 11b. Add water. Further, the process control unit 112 closes after a predetermined time has elapsed since the outer tank water supply electromagnetic valve 12d was opened. This is an operation in which air is contained in the water injection hose 11 b connected to the water supply hose connection port 4, and the air is discharged into the outer tub 9.
その後、工程制御部１１２が洗剤給水電磁弁１２ａを開弁し、水道水を投入装置１１の洗剤投入室（図示せず）に給水する。洗剤投入室に注水された水道水は、投入された洗剤とともに、外槽９内に注水される。また、工程制御部１１２は、洗剤給水電磁弁１２ａが開弁されてから所定時間経過後（または、所定水位まで到達した後）に洗剤給水電磁弁１２ａを閉弁する。 Thereafter, the process control unit 112 opens the detergent water supply electromagnetic valve 12 a and supplies tap water to a detergent charging chamber (not shown) of the charging device 11.

Further, the process control unit 112 closes the detergent water supply electromagnetic valve 12a after a predetermined time has passed since the detergent water supply electromagnetic valve 12a is opened (or after reaching a predetermined water level).
洗剤とかし工程Ｓ３では、工程制御部１１２が循環ポンプ１７（または、洗濯兼脱水槽８、または回転翼８ｂ）を駆動して洗剤を溶かし、高濃度の洗剤溶液を生成する。 In the detergent combing step S3, the process control unit 112 drives the circulation pump 17 (or the washing / dehydrating tub 8 or the rotary blade 8b) to dissolve the detergent and generate a highly concentrated detergent solution.
回転給水工程Ｓ４では、工程制御部１１２が外槽給水電磁弁１２ｄを開弁して外槽に給水し、洗濯兼脱水槽８および／または回転翼８ｂを回転させながら、循環ポンプ１７を駆動して、高濃度の洗剤溶液を糸くず除去装置１９から洗濯兼脱水槽８内の衣類に散布する。このとき、仕上剤／槽洗浄給水電磁弁１２ｂを開弁して、外槽９と洗濯兼脱水槽８を洗浄してもよい。 In the rotary water supply process S4, the process control unit 112 opens the outer tank water supply electromagnetic valve 12d to supply water to the outer tank, and drives the circulation pump 17 while rotating the washing / dehydrating tank 8 and / or the rotary blade 8b. Then, a high-concentration detergent solution is sprayed from the lint removing device 19 to the clothes in the washing and dewatering tub 8.

Then, the cloth quality (water absorption) of the clothes is determined from the weight of the clothes not including water calculated in the cloth amount sensing step S1 and the weight of the clothes including water calculated in the cloth quality sensing step S6. The following steps are controlled according to the determined cloth quality of the garment.
洗い給水工程Ｓ７では、工程制御部１１２が、布量センシング工程Ｓ１で算出した衣類の重量と、布質センシング工程Ｓ６で判断した衣類の布質に合わせて外槽９（または洗濯兼脱水槽８）の内部に給水する。また、水位検出装置３６により水位を算出する。算出した水位は、脱水・槽洗浄シャワーＳ２３で使用する槽洗浄水の供給量を決定するために用いられる。 In the washing / water supply step S7, the process control unit 112 matches the weight of the clothes calculated in the cloth amount sensing step S1 and the cloth quality of the clothes determined in the cloth quality sensing step S6. ) Supply water inside. Further, the water level is calculated by the water level detection device 36. The calculated water level is used to determine the supply amount of the tank cleaning water used in the dehydration / tank cleaning shower S23.
本洗い工程Ｓ８では、工程制御部１１２が、回転翼８ｂを回転（または、正方向逆方向に交互に回転）して、衣類を洗う。このとき、循環ポンプ１７を駆動して、洗剤溶液を衣類に散布してもよい。なお、図示していないが、本洗い工程Ｓ８では、回転翼８ｂを正方向逆方向に交互に回転させ衣類をほぐす運転も行う。また、工程制御部１１２は、この本洗い工程とほぐし工程を数回繰り返す。本洗いが終了すると、衣類のアンバランス状態を監視し、脱水に移行するか否かを判断する。 In the main washing process S8, the process control unit 112 rotates the rotor blades 8b (or alternately rotates in the forward and reverse directions) to wash the clothes. At this time, the circulation pump 17 may be driven to spray the detergent solution on the clothes. Although not shown, in the main washing step S8, the rotating blades 8b are alternately rotated in the forward and reverse directions to perform an operation of loosening clothes. Further, the process control unit 112 repeats the main washing process and the loosening process several times. When the main washing is completed, the unbalanced state of the clothing is monitored to determine whether or not to shift to dehydration.
排水工程Ｓ９では、工程制御部１１２が、排水弁１４を開弁し、外槽９内の洗い水を排水する。 In the drainage process S9, the process control unit 112 opens the drain valve 14 and drains the wash water in the outer tub 9.
脱水工程Ｓ１０では、排水終了後、工程制御部１１２が、洗濯兼脱水槽８を回転させて衣類に含まれる水（洗い水）を脱水する。 In the dehydration step S10, after the drainage is finished, the process control unit 112 rotates the washing and dewatering tank 8 to dehydrate water (wash water) contained in the clothes.
回転シャワー工程Ｓ１１では、工程制御部１１２が、排水弁１４を閉弁、外槽給水電磁弁１２ｄを開弁して、洗濯兼脱水槽８にすすぎ水を供給する。そして、洗濯兼脱水槽８を回転させつつ、すすぎ水を洗濯兼脱水槽８内の衣類に散布する。 In the rotary shower step S <b> 11, the process control unit 112 closes the drain valve 14, opens the outer tank water supply electromagnetic valve 12 d, and supplies rinse water to the washing and dewatering tank 8. Then, the rinsing water is sprayed on the clothes in the washing / dehydrating tub 8 while rotating the washing / dehydrating tub 8.
脱水工程Ｓ１２では、工程制御部１１２が、洗濯兼脱水槽８を回転させつつ、循環ポンプ１７を停止させて、衣類からすすぎ水を脱水する。 In the dehydration process S12, the process control unit 112 stops the circulation pump 17 while rotating the washing and dehydrating tub 8, and dehydrates the rinsing water from the clothes.
回転シャワー工程Ｓ１３では、工程制御部１１２が、洗濯兼脱水槽８を回転させつつ、すすぎ水を洗濯兼脱水槽８内の衣類に散布する。 In the rotary shower step S <b> 13, the process control unit 112 sprays rinse water on the clothes in the washing / dehydrating tub 8 while rotating the washing / dehydrating tub 8.
排水工程Ｓ１４では、工程制御部１１２が、洗濯兼脱水槽８および循環ポンプ１７を停止させて、排水弁１４を開弁し、外槽９内のすすぎ水を排水する。 In the draining step S14, the process control unit 112 stops the washing / dehydrating tub 8 and the circulation pump 17, opens the drain valve 14, and drains the rinsing water in the outer tub 9.
脱水工程Ｓ１５では、排水終了後、工程制御部１１２が、洗濯兼脱水槽８を回転させて衣類に含まれる水（すすぎ水）を脱水する。 In the dehydration step S15, after the drainage is finished, the process control unit 112 rotates the washing and dehydrating tank 8 to dehydrate water (rinse water) contained in the clothes.
すすぎ給水工程Ｓ１６では、工程制御部１１２が、排水弁１４を閉弁、仕上剤／槽洗浄給水電磁弁１２ｂを開弁し、洗濯兼脱水槽８を回転させながら、外槽９と洗濯兼脱水槽８を洗浄する。所定時間経過後（または、所定水位まで到達した後）に切替電磁弁１２ｅを所定時間開弁して、洗濯兼脱水槽８に仕上剤を含むすすぎ水を供給する。また、給水工程Ｓ１６では、工程制御部１１２が、外槽給水電磁弁１２ｄを開弁して、外槽９（または、洗濯兼脱水槽８）にすすぎ水を供給する。このとき、所定水位まで到達する時間を算出することで、時間当たりの水道水の流量、すなわち水道水の流量を算出する。これは、住宅ごとに水道水の流量もしくは水道圧が異なるためである。算出した水道水の流量と布量センシング工程Ｓ１で算出した布量に基づき、脱水・槽洗浄シャワーＳ２３および槽洗浄シャワーＳ２５で使用する槽洗浄水の供給量を決定する。 In the rinsing water supply step S16, the process control unit 112 closes the drain valve 14, opens the finishing agent / bath washing water supply electromagnetic valve 12b, and rotates the washing / dehydration tub 8 while washing and removing the outer tub 9. The water tank 8 is washed. After a predetermined time has elapsed (or after reaching a predetermined water level), the switching electromagnetic valve 12e is opened for a predetermined time, and rinse water containing a finishing agent is supplied to the washing and dewatering tank 8. In the water supply step S16, the process control unit 112 opens the outer tub water supply electromagnetic valve 12d and supplies rinsing water to the outer tub 9 (or the washing and dewatering tub 8). At this time, by calculating the time to reach the predetermined water level, the flow rate of tap water per hour, that is, the flow rate of tap water is calculated. This is because the flow rate or tap pressure of tap water is different for each house. Based on the calculated tap water flow rate and the cloth amount calculated in the cloth amount sensing step S1, the supply amount of the tank cleaning water used in the dewatering / tank washing shower S23 and the tank washing shower S25 is determined.
ここで、槽洗浄水の供給量を制御する方法について、詳細に説明する。槽洗浄水は、仕上剤／槽洗浄給水電磁弁１２ｂを介して外槽９内に供給されることから、仕上剤／槽洗浄給水電磁弁１２ｂの開弁時間Ｔ２３で供給量を調整する。槽洗浄水量算出部１１５が、布量センシング工程Ｓ１で算出した布量が所定の量より少ないと判断したとき、または洗い給水工程Ｓ７で算出した水位が所定の量より低いと判断したとき、槽洗浄水量を所定の量に設定する。逆に、布量が所定の量より多いと判断したとき、または水位が所定の量より高いと判断したとき、槽洗浄水量を所定の量より少ない量に設定する。ここで、槽洗浄水量は、水道水の流量と仕上剤／槽洗浄給水電磁弁１２ｂの開弁時間Ｔ２３の積で計算できる。よって、槽洗浄水量は、すすぎ給水工程Ｓ１６で算出した水道水の流量と、槽洗浄水量算出部１１５で決定した槽洗浄水量から、仕上剤／槽洗浄給水電磁弁１２ｂの開弁時間Ｔ２３を逆算し、開弁時間Ｔ２３によって制御する。 Here, a method for controlling the supply amount of the tank washing water will be described in detail. Since the tank cleaning water is supplied into the outer tank 9 via the finishing agent / tank cleaning water supply electromagnetic valve 12b, the supply amount is adjusted by the valve opening time T23 of the finishing agent / tank cleaning water supply electromagnetic valve 12b. When the tank washing water amount calculation unit 115 determines that the cloth amount calculated in the cloth amount sensing step S1 is less than the predetermined amount, or when the water level calculated in the washing water supply step S7 is determined to be lower than the predetermined amount, Set the amount of washing water to a predetermined amount. Conversely, when it is determined that the amount of cloth is greater than the predetermined amount, or when it is determined that the water level is higher than the predetermined amount, the tank washing water amount is set to an amount smaller than the predetermined amount. Here, the tank washing water amount can be calculated by the product of the flow rate of tap water and the opening time T23 of the finishing agent / tank washing water supply electromagnetic valve 12b. Therefore, the tank cleaning water amount is calculated by back-calculating the opening time T23 of the finishing agent / tank cleaning water supply electromagnetic valve 12b from the flow rate of tap water calculated in the rinsing water supply step S16 and the tank cleaning water amount determined by the tank cleaning water amount calculation unit 115. And controlled by the valve opening time T23.
ほぐし工程Ｓ１７では、工程制御部１１２が、回転翼８ｂを正方向逆方向に交互に回転させ衣類をほぐす運転を行う。 In the loosening step S <b> 17, the process control unit 112 performs an operation of loosening clothes by alternately rotating the rotary blades 8 b in the forward and reverse directions.
撹拌工程Ｓ１８では、工程制御部１１２が、外槽９にすすぎ水を溜めた状態で洗濯兼脱水槽８を回転させて衣類を撹拌しつつすすぐ。 In the stirring step S18, the process control unit 112 rinses the clothes while stirring the clothes by rotating the washing / dehydrating tub 8 while rinsing water is accumulated in the outer tub 9.
槽洗浄工程Ｓ１９では、工程制御部１１２により洗濯兼脱水槽８を回転させて、洗濯兼脱水槽８底面の上面及び下面や回転翼８ｂの裏面を洗浄する。なお、回転翼８ｂのみを回転させてもよい。 In the tank cleaning step S19, the washing / dehydrating tub 8 is rotated by the process control unit 112 to clean the upper and lower surfaces of the bottom surface of the washing / dehydrating tub 8 and the back surface of the rotary blade 8b. Only the rotary blade 8b may be rotated.
槽洗浄水供給工程Ｓ２０では、排水弁１４を開弁し、すすぎ２（最終すすぎ）で使用したすすぎ水を一度全て排水したあとに排水弁１４を閉弁し、外槽給水電磁弁１２ｄを開弁時間Ｔ２０が経過するまで開弁し、洗濯兼脱水槽８を回転させながら所定の水位まで給水する。また、仕上剤／槽洗浄給水電磁弁１２ｂから槽洗浄水を給水してもよい。槽洗浄水供給工程Ｓ２０で供給した水道水を用いて、槽洗浄工程Ｓ２１を行うことで、外槽９、洗濯兼脱水槽８、回転翼８ｂに対する汚れの付着を抑制する。槽洗浄工程Ｓ２１では、外槽９内に溜まった水を巻き上げて、外槽９、洗濯兼脱水槽８を洗浄するため、汚れの付着しやすい喫水線が低いときは洗浄水給水量が少なくてよい。したがって、開弁時間Ｔ２０は、布量センシング工程Ｓ１で算出した布量が所定の量より少ないと判断したとき、または洗い給水工程Ｓ７で算出した水位が所定の量より低いと判断したとき、短く（たとえば、３０〜９０秒）設定する。また、槽洗浄工程Ｓ１９で、外槽９内に溜まっているすすぎ水のにごりや汚れを検出する手段（図示せず）を備えている場合は、すすぎ水のにごりや汚れが少ない場合は槽洗浄水量を少なくしても良い。なお、すすぎ水のにごりや汚れを検出する手段として、光の透過率で検出する方法や、電気伝導率で検出する方法などがある。 In the tank washing water supply step S20, the drain valve 14 is opened, the rinse water used in the rinse 2 (final rinse) is drained once, the drain valve 14 is closed, and the outer tank water supply electromagnetic valve 12d is opened. The valve is opened until the valve time T20 elapses, and water is supplied to a predetermined water level while rotating the washing and dewatering tank 8. Further, the tank cleaning water may be supplied from the finishing agent / tank cleaning water supply electromagnetic valve 12b. By using the tap water supplied in the tank cleaning water supply process S20, the tank cleaning process S21 is performed, thereby suppressing the adhesion of dirt to the outer tank 9, the washing and dewatering tank 8, and the rotary blade 8b. In the tank cleaning step S21, the water collected in the outer tub 9 is rolled up to clean the outer tub 9 and the washing / dehydrating tub 8. Therefore, when the water line where dirt easily adheres is low, the amount of water supplied for cleaning water may be small. . Accordingly, the valve opening time T20 is short when it is determined that the cloth amount calculated in the cloth amount sensing step S1 is less than the predetermined amount, or when the water level calculated in the washing water supply step S7 is determined to be lower than the predetermined amount. (For example, 30 to 90 seconds). Further, in the tank cleaning step S19, when a means (not shown) for detecting dust and dirt in the rinse water accumulated in the outer tank 9 is provided, if there is little dirt and dirt in the rinse water, the tank is washed. The amount of water may be reduced. There are a method for detecting dust and dirt in the rinse water, a method for detecting by light transmittance, a method for detecting by electrical conductivity, and the like.
槽洗浄工程Ｓ２１では、槽洗浄工程１９と同様、工程制御部１１２により洗濯兼脱水槽８を回転させて、外槽９、洗濯兼脱水槽８、回転翼８ｂを洗浄する。外槽９内に溜まっている水が少ない場合においても、洗濯兼脱水槽８を前記槽洗浄工程Ｓ１９より速い回転速度（たとえば、１３０〜２５０ｒ／min）で、前記回翼８ｂと共に回転させることで、外槽９内に溜まった水が遠心力で持ち上がり、外槽９の上部の汚れを洗い流すこともできる。 In the tank washing step S21, as in the tank washing step 19, the washing / dehydrating tub 8 is rotated by the process control unit 112 to wash the outer tub 9, the washing / dehydrating tub 8, and the rotary blade 8b. Even when the amount of water accumulated in the outer tub 9 is small, the washing and dewatering tub 8 can be rotated together with the blade 8b at a higher rotational speed (for example, 130 to 250 r / min) than the tub cleaning step S19. The water accumulated in the outer tub 9 is lifted by centrifugal force, and the upper portion of the outer tub 9 can be washed away.
ここで、回転翼８ｂの構造について、詳細に説明する。
図２０は、回転翼８ｂを上方から見た表側の図であり、図２１は、回転翼８ｂを下方から見た裏側の図であり、図２２は、図２０のＡ−Ａ断面図である。この回転翼８ｂは、内槽８の内底面部を一部または全部覆うような径を有する略円形に形成されている。
Here, the structure of the rotary blade 8b will be described in detail.
20 is a front side view of the rotary blade 8b as viewed from above, FIG. 21 is a back side view of the rotary blade 8b as viewed from below, and FIG. 22 is a cross-sectional view taken along line AA in FIG. . The rotor blade 8b is formed in a substantially circular shape having a diameter that covers part or all of the inner bottom surface of the inner tank 8.
図２０に示す通り、回転翼８ｂには、中心側から外径側にかけて次第に高く形成される山部８ｂ１を複数、例えば二つ有している。この山部８ｂ１は、回転方向に波型に傾斜しており、その波型の頂部が中心側から外径側にかけて連なることにより峰部を形成する。このため、回転翼８ｂが回転すると、峰部により衣類が跳ね上がり、効率良く衣類の入れ替わりが行われる。 As shown in FIG. 20, the rotor blade 8b has a plurality of, for example, two peak portions 8b1 that are gradually formed higher from the center side to the outer diameter side. The peak portion 8b1 is inclined in a wave shape in the rotation direction, and the peak portion of the wave shape is continuous from the center side to the outer diameter side to form a peak portion. For this reason, when the rotary blade 8b rotates, the clothing jumps up by the peak portion, and the clothing is efficiently replaced.
さらに、回転翼８ｂにおける複数の山部８ｂ１の間には、略平坦な谷部８ｂ２を複数、例えば二つ有している。この谷部８ｂ２には、中心側から外径側にかけて放射状かつ互い違いに複数の凸部８ｂ３が形成されている。この凸部８ｂ３により、山部８ｂ１から落下される衣類に指圧的効果を与えたり、衣類の動きを活性化したりでき、結果として洗浄力の向上につながる。また、谷部８ｂ２には、複数の谷部貫通孔８ｂ４が設けられており、衣類と回転翼８ｂとの間に水膜が形成されるのを防止している。 Further, a plurality of, for example, two substantially flat valley portions 8b2 are provided between the plurality of peak portions 8b1 of the rotary blade 8b. In the valley portion 8b2, a plurality of convex portions 8b3 are formed radially and alternately from the center side to the outer diameter side. By this convex part 8b3, a shiatsu effect can be given to the clothing dropped from the mountain part 8b1, or the movement of the clothes can be activated, resulting in an improvement in cleaning power. Further, the valley portion 8b2 is provided with a plurality of valley portion through holes 8b4 to prevent a water film from being formed between the clothing and the rotor blade 8b.
この回転翼８ｂの裏側には、図２１及び図２２に示す通り、周方向リブ８ｂ５及び径方向リブ８ｂ６が強度確保等のために設けられている。ここで、これら周方向リブ８ｂ５及び径方向リブで仕切られる空間のうち、特に山部８ｂ１の裏側に形成される仕切空間８ｂ７には空気が溜り易く、汚れが残ることがある。しかしながら、本実施形態のように山部貫通孔８ｂ８を設けることにより、回転翼８ｂの裏側から表側に至る水の流れが生まれ、この仕切空間８ｂ７への汚れの付着を抑制できる。また、仕切空間８ｂ７の外径側に山部貫通孔８ｂ８を形成すれば、高い遠心力が作用して水の流れが更に良くなる。 As shown in FIGS. 21 and 22, circumferential ribs 8b5 and radial ribs 8b6 are provided on the back side of the rotary blade 8b to ensure strength and the like. Here, among the spaces partitioned by the circumferential ribs 8b5 and the radial ribs, air easily collects in the partition space 8b7 formed on the back side of the peak portion 8b1, and dirt may remain. However, by providing the peak portion through-hole 8b8 as in the present embodiment, a flow of water from the back side to the front side of the rotary blade 8b is produced, and adhesion of dirt to the partition space 8b7 can be suppressed. Moreover, if the peak part through-hole 8b8 is formed in the outer diameter side of the partition space 8b7, a high centrifugal force will act and the flow of water will become still better.
また、山部貫通孔８ｂ８を設ける位置としては、山部８ｂ１における周方向端部と峰部との間であって、周方向端部寄りが望ましい。すると、峰部付近には山部貫通孔８ｂ８が存在しないので、衣類の引っ掛かりを防止できる。なお、この山部貫通孔８ｂ８や谷部貫通孔８ｂ４は、排水だけでなく、乾燥時の温風も通ることになる。 Moreover, as a position which provides the mountain part through-hole 8b8, it is between the circumferential direction edge part and peak part in the mountain part 8b1, Comprising: The circumferential direction edge part vicinity is desirable. Then, since the mountain through hole 8b8 does not exist in the vicinity of the peak, clothes can be prevented from being caught. In addition, this peak part through-hole 8b8 and valley part through-hole 8b4 pass not only waste water but the warm air at the time of drying.
次に、図１６を用いて、槽洗浄工程Ｓ１９の動作について更に説明する。
工程制御部１１２は、すすぎ水が所定の水位ｓ以下かどうかを判断し（ステップ１６１）、所定水位ｓより水位が高い場合は排水弁１４を開弁して、すすぎ水を排水する（ステップ１６２）。この所定水位ｓは、たとえば、洗濯兼脱水槽８の底面や回転翼８ｂ底面よりも高い水位とする。所定水位ｓ以下になったら、排水弁１４を閉弁する（ステップ１６３）。
Next, operation | movement of tank cleaning process S19 is further demonstrated using FIG.
The process control unit 112 determines whether or not the rinse water is equal to or lower than the predetermined water level s (step 161). If the water level is higher than the predetermined water level s, the process control unit 112 opens the drain valve 14 to drain the rinse water (step 162). ). The predetermined water level s is, for example, higher than the bottom surface of the washing / dehydrating tub 8 and the bottom surface of the rotary blade 8b. When the water level falls below the predetermined water level s, the drain valve 14 is closed (step 163).
この後、工程制御部１１２は、洗濯兼脱水槽８を、前記回転給水工程Ｓ４、回転シャワー工程Ｓ１１、Ｓ１３での回転数（３５ｒ／min）よりも速い回転速度（たとえば、８０〜１３０ｒ／min）で、回転させる（ステップ１６４）。なお、洗濯兼脱水槽８を回転させるパターンとして、正方向（一方向）に回転させる以外に、逆方向に回転させるようにしてもよく、正方向と逆方向を交互に繰り返して回転させてもよい。 Thereafter, the process control unit 112 causes the washing and dewatering tub 8 to rotate at a rotational speed (for example, 80 to 130 r / min) faster than the rotational speed (35 r / min) in the rotary water supply process S4 and the rotary shower processes S11 and S13. ) (Step 164). As a pattern for rotating the washing and dewatering tub 8, in addition to rotating in the forward direction (one direction), the washing / dehydrating tub 8 may be rotated in the reverse direction, or may be rotated alternately in the forward direction and the reverse direction. Good.
所定時間ｔ（たとえば、９０〜１２０秒）経過したか判断し（ステップ１６５）、所定時間ｔ経過したなら、洗濯兼脱水槽８を停止させる（ステップ１６６）。ステップ１６６で洗濯兼脱水槽８を停止させているが、ステップ１６７で槽洗浄水の供給を行わない場合は、必ずしも洗濯兼脱水槽８を停止させる必要はなく、回転させたまま脱水工程に移行してもよい。 It is determined whether a predetermined time t (for example, 90 to 120 seconds) has elapsed (step 165). If the predetermined time t has elapsed, the washing and dewatering tub 8 is stopped (step 166). The washing / dehydrating tub 8 is stopped in step 166, but if the tank washing water is not supplied in step 167, it is not always necessary to stop the washing / dehydrating tub 8, and the process proceeds to the dehydration process while rotating. May be.
ステップ１６７で槽洗浄水の供給を行うと判断した場合は、排水弁１４を開弁し、すすぎ２（最終すすぎ）で使用したすすぎ水を一度全て排水したあとに排水弁１４を閉弁し、ステップ１６８で外槽給水電磁弁１２ｄを開弁し、ステップ１６９で所定時間Ｔ２０が経過したか判断し、所定時間Ｔ２０が経過したなら、外槽給水電磁弁１２ｄを閉弁する（ステップ１７０）。そして、洗濯兼脱水槽８を回転させて（ステップ１６４）、槽洗浄を行う。 If it is determined in step 167 that the tank washing water is to be supplied, the drain valve 14 is opened, and after the rinse water used in the rinse 2 (final rinse) is completely drained, the drain valve 14 is closed. In step 168, the outer tank water supply electromagnetic valve 12d is opened. In step 169, it is determined whether the predetermined time T20 has elapsed. If the predetermined time T20 has elapsed, the outer tank water supply electromagnetic valve 12d is closed (step 170). Then, the washing and dewatering tank 8 is rotated (step 164) to perform tank cleaning.
槽洗浄工程Ｓ１９およびＳ２１は、すすぎ水（または、水道水）が外槽９の底に溜められた状態で洗濯兼脱水槽８を回転させるので、洗濯兼脱水槽８の外側の底面や回転翼８ｂ底面に付着した汚れやゴミを除去することができ、また汚れやゴミが付着するのを抑制することができる。また、回転翼８ｂにおける山部８ｂ１にも山部貫通孔８ｂ８が設けられているので、山部８ｂ１の裏側に形成される仕切空間８ｂ７についても、汚れの付着を抑制できる。さらに、ステップ１６４の洗濯兼脱水槽８の回転速度を大きくすることで、溜まっている水が遠心力で外槽内周面９ｓを伝って上側に持ち上がり、洗濯兼脱水槽８の外周面８ｓと外槽９の内周面９ｓの上部に水を流すことができる。このことで、循環ポンプ１７がなくとも、洗濯兼脱水槽８と外槽９の上部に汚れが付着するのを抑制できる。なお、洗濯兼脱水槽８の代わりに回転翼８ｂを回転させてもよい。 The tank washing steps S19 and S21 rotate the washing / dehydrating tub 8 in a state where rinse water (or tap water) is accumulated at the bottom of the outer tub 9, so that the bottom surface and the rotating blades outside the washing / dehydrating tub 8 are rotated. The dirt and dust adhering to the bottom surface of 8b can be removed, and the adhesion of dirt and dust can be suppressed. Moreover, since the peak part through-hole 8b8 is provided also in the peak part 8b1 in the rotary blade 8b, adhesion of dirt can also be suppressed about the partition space 8b7 formed in the back side of the peak part 8b1. Further, by increasing the rotational speed of the washing / dehydrating tub 8 in step 164, the accumulated water is lifted upward along the inner peripheral surface 9s of the outer tub by centrifugal force. Water can flow over the inner peripheral surface 9 s of the outer tub 9. Thus, even without the circulation pump 17, it is possible to prevent dirt from adhering to the upper portions of the washing / dehydrating tub 8 and the outer tub 9. In addition, you may rotate the rotary blade 8b instead of the washing and dewatering tank 8. FIG.
槽洗浄工程Ｓ１９が終了すると、工程制御部１１２は、衣類のアンバランス状態を監視し、最終脱水に移行するか否かを判断する。 When the tank cleaning step S19 is completed, the process control unit 112 monitors the clothing imbalance state and determines whether or not to proceed to final dehydration.
排水工程Ｓ２０では、工程制御部１１２が、排水弁１４を開弁し、外槽９内のすすぎ水を排水する。 In the drainage process S20, the process control unit 112 opens the drain valve 14 to drain the rinse water in the outer tub 9.
脱水・槽洗浄シャワー工程Ｓ２１では、排水終了後、工程制御部１１２が、洗濯兼脱水槽８を高速で回転させて衣類に含まれる水分を取り除く。この脱水・槽洗浄シャワー工程Ｓ２１では、脱水のために洗濯兼脱水槽８の回転数を上昇させる途中段階（所定の回転数となったとき）に、後述する散水口から水を噴射する槽洗浄シャワーの動作を取り入れており、その動作について、図１７を用いて更に説明する。 In the dehydration / tank washing shower process S21, after the drainage is completed, the process control unit 112 rotates the washing / dehydrating tank 8 at a high speed to remove moisture contained in the clothes. In this dehydration / tank washing shower step S21, the tank washing in which water is jetted from a sprinkler, which will be described later, in the middle of increasing the rotation speed of the washing and dehydration tank 8 for dehydration (when it reaches a predetermined rotation speed). A shower operation is taken in, and the operation will be further described with reference to FIG.
工程制御部１１２が、洗濯兼脱水槽８を回転させ、段階的に加速する（ステップ１７１）。所定回転数ｎ1（たとえば、４００ｒ／min）以下かどうかを判断する（ステップ１７２）。所定回転数ｎ1に達すると、所定回転数ｎ1を維持（ステップ１７３）したまま、仕上剤／槽洗浄給水電磁弁１２ｂを開弁して、水路部材５０に槽洗浄水（水道水）を供給する（ステップ１７４）。所定時間Ｔ２３（たとえば、３０〜１２０秒）が経過するまで、水路部材５０に給水する（ステップ１７５）。ここで、洗濯兼脱水槽８の回転方向に延びる給水経路には後述の散水口が複数設けられており、この散水口から噴射された水道水が外槽９の内壁面または洗濯兼脱水槽８の外壁面に沿って重力で流れ落ちる結果、外槽９や洗濯兼脱水槽８に汚れが付着し難くなる。前記所定時間Ｔ２３が経過したなら、仕上剤／槽洗浄給水電磁弁１２ｂを閉弁し（ステップ１７６）、洗濯兼脱水槽８を更に加速し（ステップ１７７）、脱水を継続して衣類に含まれる水分を取り除く。 The process control unit 112 rotates the washing and dewatering tub 8 and accelerates it step by step (step 171). It is determined whether the rotation speed is equal to or less than a predetermined rotation speed n 1 (for example, 400 r / min) (step 172). When the predetermined rotational speed n 1 is reached, the finishing agent / tank washing water supply electromagnetic valve 12b is opened while maintaining the predetermined rotational speed n 1 (step 173), and the tank cleaning water (tap water) is supplied to the water channel member 50. Supply (step 174). Water is supplied to the channel member 50 until a predetermined time T23 (for example, 30 to 120 seconds) elapses (step 175). Here, the water supply path extending in the rotation direction of the washing / dehydrating tub 8 is provided with a plurality of water spouts to be described later, and tap water sprayed from the water spouts is the inner wall surface of the outer tub 9 or the washing / dehydrating tub 8. As a result of gravity flowing down along the outer wall surface, dirt does not easily adhere to the outer tub 9 and the washing / dehydrating tub 8. When the predetermined time T23 has elapsed, the finish / tank washing water supply electromagnetic valve 12b is closed (step 176), the washing and dewatering tank 8 is further accelerated (step 177), and dehydration is continued to be included in the clothing. Remove moisture.
所定回転数ｎ1を保持した場合で説明したが、所定回転数ｎ1に限定される必要はなく、所定回転数ｎ2（たとえば６００ｒ／min）を設定し、所定回転数ｎ1〜所定回転数ｎ2の加速中に実行してもよく、さらには、所定回転数ｎ2を所定時間ｔ2（たとえば、３０〜１２０秒）保持して実行してもよい。 Although the case where the predetermined rotational speed n 1 is held has been described, it is not necessary to be limited to the predetermined rotational speed n 1. A predetermined rotational speed n 2 (for example, 600 r / min) is set, and the predetermined rotational speed n 1 to the predetermined rotational speed are set. it may be performed during the acceleration of the number n 2, further a predetermined rotational speed n 2 predetermined time t 2 (e.g., 30 to 120 seconds) may be executed to hold.
給水部材５０に給水すると、図１２に示すように、水路部材５０の側面側散水口５０ｂ１から水道水が吐出され、実線矢印で示すように、外槽カバー９ａに形成された凹部９ａ１の底面９ａ２に当たり、そして洗濯兼脱水槽８のバランスリング８ｃの外周縁部上面８ｃ１に降りかかる。このとき、洗濯兼脱水槽８は高速で回転しているで、バランスリング８ｃの外周縁部上面８ｃ１に降りかかった水道水は、洗濯兼脱水槽８の回転時の遠心力によって外槽９の内周面９ｓに向けて吹き飛ばされる。外槽９の内周面９ｓまで飛ばされた水道水は、重力の作用により外槽９の内周面９ｓを鉛直方向下方に向けて流れ落ちる。また、水路部材５０に側面側散水口５０ｂ１が複数形成されるとともに遠心力によって吹き飛ばされるので、外槽９の上部において、その内周面９ｓの全体に水道水が吹き付けられ、その後下方に流れ落ちる。したがって、外槽９の内周面の上部から下部までの全体に水道水が流れることになる。よって、外槽９の内周面の全体の汚れやゴミが取り除かれ、また汚れやゴミの付着を抑制することができる。 When water is supplied to the water supply member 50, as shown in FIG. 12, tap water is discharged from the side surface water sprinkling port 50b1 of the water channel member 50, and the bottom surface 9a2 of the recess 9a1 formed in the outer tub cover 9a as shown by the solid line arrow. Then, it falls on the outer peripheral edge upper surface 8c1 of the balance ring 8c of the washing and dewatering tub 8. At this time, since the washing / dehydrating tub 8 is rotating at a high speed, the tap water that has fallen on the outer peripheral edge upper surface 8c1 of the balance ring 8c is caused by the centrifugal force generated when the washing / dehydrating tub 8 is rotated. It is blown off toward the inner peripheral surface 9s. The tap water blown to the inner peripheral surface 9s of the outer tub 9 flows down the inner peripheral surface 9s of the outer tub 9 downward in the vertical direction by the action of gravity. Further, since a plurality of side surface water sprinkling ports 50b1 are formed in the water channel member 50 and blown off by centrifugal force, tap water is sprayed on the entire inner peripheral surface 9s in the upper part of the outer tub 9, and then flows downward. Therefore, tap water flows through the entire inner peripheral surface of the outer tub 9 from the upper part to the lower part. Accordingly, the entire dirt and dust on the inner peripheral surface of the outer tub 9 are removed, and adhesion of dirt and dust can be suppressed.
また、図１２に示すように、水路部材５０の底面側散水口５０ａ１から水道水が散水されると、洗濯兼脱水槽８の上部（バランスリング８ｃ）の外周面８ｓに吹き付けられる。外周面８ｓに吹き付けられた水道水は、重力の作用により洗濯兼脱水槽８の外周面８ｓを鉛直方向下方に向けて流れ落ちる。なお、側面側散水口５０ｂ１から外周縁部上面８ｃ１に滴下した水道水の一部も、図１２において細い破線で示すように、重力の作用により、洗濯兼脱水槽８の外周面８ｓを下方へと流れ落ちる。 As shown in FIG. 12, when tap water is sprinkled from the bottom side sprinkling port 50a1 of the water channel member 50, it is sprayed to the outer peripheral surface 8s of the upper part (balance ring 8c) of the washing and dewatering tub 8. The tap water sprayed on the outer peripheral surface 8s flows down the outer peripheral surface 8s of the washing and dewatering tub 8 vertically downward by the action of gravity. Note that a part of tap water dripped from the side-side water spout 50b1 to the outer peripheral edge upper surface 8c1 also moves downward on the outer peripheral surface 8s of the washing and dewatering tub 8 by the action of gravity, as shown by a thin broken line in FIG. And flow down.
このようにして、水路部材５０の側面側散水口５０ｂ１と底面側散水口５０ａ１から水道水を洗濯兼脱水槽８の上部（外周縁部）に散水することにより、外槽９の内周面９ｓおよび洗濯兼脱水槽８の外周面８ｓに対する汚れやごみの付着を抑制することができる。 In this way, by sprinkling tap water from the side surface watering port 50b1 and the bottom surface side watering port 50a1 of the water channel member 50 to the upper part (outer peripheral edge portion) of the washing and dewatering tank 8, the inner peripheral surface 9s of the outer tank 9 is obtained. In addition, it is possible to suppress the adhesion of dirt and dust to the outer peripheral surface 8s of the washing and dewatering tub 8.
なお、洗濯から乾燥までの一連の運転を行うモードが設定されている場合には、脱水工程Ｓ２１後に乾燥工程Ｓ２２を行う。乾燥工程Ｓ２２では、工程制御部１１２が、冷却水給水電磁弁１２ｃを開弁して、ヒータ２２を通電し、ファン２１を駆動させる。乾燥工程（Ｓ２２）終了後、ユーザが外蓋３および蓋部材９ｃを開いて乾燥した衣類を取り出し、蓋部材９ｃおよび外蓋３を閉め、所定のボタン（例えばスタートボタン）を押すことで、以下の槽洗浄シャワー工程Ｓ２３が開始される。 In addition, when the mode which performs a series of operation | movement from washing to drying is set, drying process S22 is performed after spin-drying | dehydration process S21. In the drying step S22, the process control unit 112 opens the cooling water supply electromagnetic valve 12c, energizes the heater 22, and drives the fan 21. After the drying step (S22), the user opens the outer lid 3 and the lid member 9c, takes out the dried clothes, closes the lid member 9c and the outer lid 3, and presses a predetermined button (for example, a start button), The tank washing shower process S23 is started.
槽洗浄シャワー工程Ｓ２３では、衣類重量算出部１１４により洗濯兼脱水槽８内に衣類が残っていないかを判断し、衣類がない場合は、前記脱水・槽洗浄シャワー工程Ｓ２１の槽洗浄シャワー動作と同様であり、洗濯兼脱水槽８の外周面８ｓや外槽９の内周面９ｓに水路部材５０から水道水を散水する。槽洗浄シャワー工程Ｓ２３では、槽洗浄シャワー動作により水道水を散水した後に、排水弁１４を開弁して水を排水した後に、ヒータ２２を通電し、ファン２１を駆動させて、外槽９及び洗濯兼脱水槽８を乾燥させ、カビの繁殖や異臭の発生を抑制することも可能である。 In the tub washing shower step S23, the garment weight calculating unit 114 determines whether or not clothing remains in the washing and dewatering tub 8. If there is no clothing, the tub washing shower operation in the dehydration and tub washing shower step S21 is performed. Similarly, tap water is sprayed from the water channel member 50 to the outer peripheral surface 8 s of the washing and dewatering tub 8 and the inner peripheral surface 9 s of the outer tub 9. In the tank cleaning shower step S23, tap water is sprinkled by the tank cleaning shower operation, and then the drain valve 14 is opened to drain the water. Then, the heater 22 is energized and the fan 21 is driven, and the outer tank 9 and It is also possible to dry the washing and dewatering tank 8 and suppress the growth of mold and the generation of off-flavors.
なお、槽洗浄工程Ｓ１９、脱水・槽洗浄シャワー工程Ｓ２１、槽洗浄シャワー工程Ｓ２３の槽洗浄、槽洗浄シャワー動作は、洗濯乾燥機１Ａに設けられたボタンによってＯＮ／ＯＦＦを設定でき、ユーザが選択可能となっている。 The tank cleaning and tank cleaning shower operations of the tank cleaning process S19, dehydration / tank cleaning shower process S21, and tank cleaning shower process S23 can be set ON / OFF by a button provided on the washing / drying machine 1A, and can be selected by the user. It is possible.
図１８は、第１の実施形態に係る洗濯乾燥機１Ａにおける操作部分の変形例を示す図である。自動槽洗浄用ボタン２５を設定した状態で洗濯コースを開始すると、槽洗浄工程Ｓ１９及び脱水・槽洗浄シャワー工程Ｓ２１が行われ、設定しない状態で洗濯コースを開始すると、これらの槽洗浄は行われない。 FIG. 18 is a diagram illustrating a modified example of the operation portion in the washing / drying machine 1A according to the first embodiment. When the washing course is started with the automatic tank washing button 25 set, the tank washing process S19 and the dehydration / tank washing shower process S21 are performed. When the washing course is started without setting, the tank washing is performed. Absent.
また、自動槽洗浄用ボタン２５を設定した状態で洗濯乾燥コースを開始すると、まず、洗濯コースと同様に、槽洗浄工程Ｓ１９〜Ｓ２１及び脱水・槽洗浄シャワー工程Ｓ２３が行われる。槽洗浄水供給工程Ｓ２０と槽洗浄工程Ｓ２１は、行わなくてもよい。その後、乾燥工程Ｓ２４が終了したとき、自動槽洗浄用ボタン２５は点灯又は点滅の状態となっている。このとき、必要に応じて、槽洗浄シャワー工程Ｓ２５に移行するための操作方法を使用者に対して音声案内する機能を設けても良い。そして、使用者が乾燥後の衣類を取り出した後、スタートボタン２６（又は自動槽洗浄用ボタン２５）を操作すると、槽洗浄シャワー工程Ｓ２５を開始し、電源ボタン２７を操作すると、槽洗浄シャワー工程Ｓ２５を実施せずに終了する。なお、乾燥工程Ｓ２４が終了してから所定時間を経過すると、自動槽洗浄用ボタン２５が消灯し、電源が切れる。 When the washing / drying course is started with the automatic tank washing button 25 set, first, the tank washing steps S19 to S21 and the dehydration / bath washing shower step S23 are performed as in the washing course. The tank cleaning water supply process S20 and the tank cleaning process S21 may not be performed. Then, when drying process S24 is complete | finished, the button 25 for automatic tank washing | cleaning will be in the state of lighting or blinking. At this time, you may provide the function which carries out voice guidance with respect to the user for the operation method for transfering to tank washing shower process S25 as needed. And if a user operates the start button 26 (or automatic tank washing button 25) after taking out the clothes after drying, tank washing shower process S25 will be started, and if the power button 27 is operated, tank washing shower process The process ends without carrying out S25. In addition, when predetermined time passes after drying process S24 is complete | finished, the button 25 for automatic tank washing | cleaning will turn off and a power supply will be turned off.
このように、使用者が衣類を取り出し終わったことを確認するためのボタン操作等を設けることで、洗濯兼脱水槽８内に乾燥後の衣類が入ったまま槽洗浄シャワー工程Ｓ２５を開始するのを防止できる。また、衣類が残ったまま槽洗浄シャワーする可能性を排除するために、乾燥後の槽洗浄シャワー工程Ｓ２５を設けないようにしても構わない。 In this way, by providing a button operation or the like for confirming that the user has finished taking out the clothes, the tank washing shower process S25 is started while the clothes after drying remain in the washing and dewatering tank 8. Can be prevented. Moreover, in order to exclude the possibility of performing a bath washing shower with clothing remaining, the bath washing shower step S25 after drying may not be provided.
更に、槽洗浄工程Ｓ１９〜Ｓ２１又は脱水・槽洗浄シャワー工程Ｓ２１を、自動槽洗浄用ボタン２５の設定の有無に係わらず、必ず実施するようにし、槽洗浄シャワーＳ２５のみを自動槽洗浄用ボタン２５で選択できるようにすることも考えられる。 Furthermore, the tank washing steps S19 to S21 or the dehydration / bath washing shower process S21 are always carried out regardless of whether or not the automatic tank washing button 25 is set, and only the tank washing shower S25 is subjected to the automatic tank washing button 25. It is also possible to make it possible to select with.
以上説明したように、第１実施形態に係る洗濯乾燥機１Ａでは、外槽カバー９ａに、洗濯兼脱水槽８の周方向に延びる給水経路（水路部材５０）が設けられ、この給水経路に給水ユニット１２Ａ（給水手段）から供給された水道水を洗濯兼脱水槽８の上部（外周縁部上面８ｃ１）に散水する側面側散水口５０ｂ１が設けられている。これによれば、洗濯兼脱水槽８の回転時に水路部材５０に給水することで、外槽９の内周面９ｓに水道水を吹き飛ばすことで、外槽９の内周面９ｓに付着した汚れやゴミを取り除くことができ、また汚れやゴミの付着を抑制することができる。このようにして汚れやゴミの付着を抑制できることで、カビの繁殖や異臭の発生を抑制することが可能になる。さらに、洗濯中の洗濯物へのゴミの付着も防止または抑制することができる。 As described above, in the washing / drying machine 1A according to the first embodiment, the outer tub cover 9a is provided with the water supply path (water channel member 50) extending in the circumferential direction of the washing and dewatering tub 8, and water is supplied to the water supply path. A side-side water sprinkling port 50b1 for spraying tap water supplied from the unit 12A (water supply means) to the upper portion (outer peripheral surface 8c1) of the washing and dewatering tub 8 is provided. According to this, by supplying water to the water channel member 50 during rotation of the washing and dewatering tub 8, the tap water is blown off to the inner peripheral surface 9s of the outer tub 9, thereby adhering to the inner peripheral surface 9s of the outer tub 9. And dust can be removed, and adhesion of dirt and dust can be suppressed. By suppressing the adhesion of dirt and dust in this way, it is possible to suppress the growth of mold and the generation of off-flavors. Furthermore, it is possible to prevent or suppress dust from adhering to the laundry being washed.
また、第１実施形態では、洗濯兼脱水槽８の外周面８ｓ（バランスリング８ｃの外周面）または上面に散水する底面側散水口５０ａ１が設けられているので、洗濯兼脱水槽８の外周面８ｓに付着した汚れやゴミを取り除くことができ、また汚れやゴミの付着を抑制することができる。 In the first embodiment, the outer peripheral surface 8s of the washing and dewatering tub 8 (the outer peripheral surface of the balance ring 8c) or the bottom surface side sprinkling port 50a1 is provided on the upper surface. Dirt and dust attached to 8s can be removed, and adhesion of dirt and dust can be suppressed.
さらに、第１の実施形態では、給水手段により外槽９内に水を溜めた状態ですすぎ工程を実行し、このすすぎ工程で利用した水が排水弁１４を開けることで排水され、所定の水位（例えば、洗濯兼脱水槽８の底面下端よりも高い水位）となったときに、排水弁１４を閉じて、すすぎ工程における洗濯兼脱水槽８よりも高速で回転させ、所定時間経過後に、脱水工程へ移行することにより、水を節約しながら、外槽９や洗濯兼脱水槽８の底面、回転翼８ｂの裏側などに汚れが付着するのを抑制できる。 Furthermore, in the first embodiment, the rinsing process is executed in a state where water is stored in the outer tub 9 by the water supply means, and the water used in this rinsing process is drained by opening the drain valve 14, and a predetermined water level (For example, when the water level is higher than the bottom bottom edge of the washing / dehydrating tub 8), the drain valve 14 is closed and rotated at a higher speed than the washing / dehydrating tub 8 in the rinsing process. By shifting to the process, it is possible to prevent dirt from adhering to the outer tub 9, the bottom surface of the washing / dehydrating tub 8, the back side of the rotary blade 8b, etc. while saving water.
以上で説明した汚れには、衣類に付着した皮脂のようなタンパク質の汚れも含まれており、それらはカビの繁殖に必要な栄養源でもある。本発明によれば、これらタンパク質の汚れも洗い流すことができるため、たとえ運転後にカビの胞子が外槽９，洗濯兼脱水槽８，回転翼８ｂに付着しても、カビの繁殖を防止，抑制できる。 The soils described above include protein soils such as sebum attached to clothing, which are also nutrient sources necessary for mold growth. According to the present invention, since these protein stains can be washed away, even if mold spores adhere to the outer tub 9, the washing / dehydrating tub 8, and the rotary blade 8b after operation, the growth of mold is prevented and suppressed. it can.
また、槽洗浄水量算出部１１５が、衣類重量算出部１１４で算出した衣類の量、または水位検出装置３６で算出した水位に基づき、外槽給水電磁弁１２ｄの開弁時間Ｔ２０と仕上剤／槽洗浄給水電磁弁１２ｂの開弁時間Ｔ２３を制御することで、使用水量を抑えることができる。つまり、衣類が少ない場合（水位が低い場合）、外槽給水電磁弁１２ｄの開弁時間Ｔ２０を短くし、衣類が多い場合（水位が高い場合）、仕上剤／槽洗浄給水電磁弁１２ｂの開弁時間Ｔ２３を短くすることで、使用水量を抑えながら槽洗浄を行うことができる。なお、本実施形態は開弁時間Ｔ２０およびＴ２３を二段階で分けているが、三段階以上としてもよい。 Further, based on the amount of clothes calculated by the garment weight calculation unit 114 or the water level calculated by the water level detection device 36 by the tank washing water amount calculation unit 115, the opening time T20 of the outer tank water supply electromagnetic valve 12d and the finishing agent / tank By controlling the valve opening time T23 of the cleaning water supply electromagnetic valve 12b, the amount of water used can be suppressed. That is, when there is little clothing (when the water level is low), the opening time T20 of the outer tank water supply electromagnetic valve 12d is shortened, and when there is much clothing (when the water level is high), the finish agent / tank washing water supply electromagnetic valve 12b is opened. By shortening the valve time T23, the tank can be washed while reducing the amount of water used. In this embodiment, the valve opening times T20 and T23 are divided in two stages, but may be three or more stages.
以上のように、第１の実施形態では、衣類の量または外槽９内の水位を検知する検知手段を備え、検知結果に応じて槽洗浄水量を制御することで、外槽９内壁、内槽８外壁または内槽８の内底面部に配置された回転翼８ｂの裏面への汚れ付着を抑制しつつも節水することができる。槽洗浄水量の制御は、少なくとも内槽８、外槽９または回転翼８ｂのいずれか一つを洗浄する槽洗浄運転で行う。 As described above, in the first embodiment, the detection unit that detects the amount of clothes or the water level in the outer tub 9 is provided, and the inner wall of the outer tub 9 is controlled by controlling the amount of water to be washed according to the detection result. Water can be saved while suppressing the adhesion of dirt to the back surface of the rotary blade 8b arranged on the outer wall of the tank 8 or the inner bottom surface of the inner tank 8. The tank cleaning water amount is controlled by a tank cleaning operation for cleaning at least one of the inner tank 8, the outer tank 9, and the rotary blade 8b.

FIG. 13 is a schematic view showing a washing machine (washing and drying machine) according to the second embodiment, FIG. 14 is a schematic view showing a water channel member of the washing machine (washing and drying machine) according to the second embodiment, and FIG. It is the schematic which shows the modification of the channel member of the washing machine (washing / drying machine) which concerns on embodiment.
図１３に示すように、洗濯乾燥機（洗濯機）１Ｂは、第１実施形態と同様に、縦型式洗濯乾燥機であり、第１実施形態に係る給水ユニット１２Ａに替えて給水ユニット１２Ｂを備えたものである。給水ユニット１２Ｂは、メイン（外槽給水）用としての外槽給水電磁弁１２ｍ、仕上剤給水電磁弁１２ｎ、冷却水給水電磁弁１２ｏ、槽洗浄給水電磁弁１２ｐを備えている。 As shown in FIG. 13, the washing / drying machine (washing machine) 1B is a vertical type washing / drying machine, similarly to the first embodiment, and includes a water supply unit 12B instead of the water supply unit 12A according to the first embodiment. It is a thing. The water supply unit 12B includes an outer tank water supply electromagnetic valve 12m, a finishing agent water supply electromagnetic valve 12n, a cooling water supply electromagnetic valve 12o, and a tank cleaning water supply electromagnetic valve 12p for main (outer tank water supply).
外槽給水電磁弁１２ｍは、制御装置１００（工程制御部１１２）によって開弁されることにより、給水ホース接続口４からの水道水を、投入装置１１の洗剤投入室（図示せず）を通って外槽９内に給水するように構成されている。 The outer tank water supply electromagnetic valve 12m is opened by the control device 100 (process control unit 112), so that tap water from the water supply hose connection port 4 passes through a detergent charging chamber (not shown) of the charging device 11. And water is supplied into the outer tub 9.
仕上剤給水電磁弁１２ｎは、制御装置１００（工程制御部１１２）によって開弁されることにより、給水ホース接続口４からの水道水を、投入装置１１の仕上剤投入室（図示せず）を通って外槽９内に給水するように構成されている。 The finishing agent water supply solenoid valve 12n is opened by the control device 100 (process control unit 112), so that tap water from the water supply hose connection port 4 is supplied to the finishing agent supply chamber (not shown) of the input device 11. It is configured to feed water into the outer tub 9 through.
冷却水給水電磁弁１２ｏは、制御装置１００（工程制御部１１２）によって開弁されることにより、給水ホース接続口４からの水道水を、図示しないホースを介して、乾燥ダクト２０（図２参照）の水冷除湿機構（図示せず）に給水するように構成されている。 When the cooling water supply electromagnetic valve 12o is opened by the control device 100 (process control unit 112), tap water from the water supply hose connection port 4 is supplied to the drying duct 20 (see FIG. 2) via a hose not shown. ) Is supplied to a water-cooled dehumidifying mechanism (not shown).
槽洗浄給水電磁弁１２ｐは、制御装置１００（工程制御部１１２）によって開弁されることにより、給水ホース接続口４からの水道水を、水路部材５０（給水経路）に水道水を供給するように構成されている。槽洗浄給水電磁弁１２ｐの開弁時間は、第一実施形態と同様に、衣類の量が多い場合（水位が高い場合）、短く（たとえば、３０〜９０秒）設定することで、使用水量を抑えている。 The tank cleaning water supply electromagnetic valve 12p is opened by the control device 100 (process control unit 112) so that tap water from the water supply hose connection port 4 is supplied to the water channel member 50 (water supply path). It is configured. As in the first embodiment, the opening time of the tank cleaning water supply electromagnetic valve 12p is set short (for example, 30 to 90 seconds) when the amount of clothing is large (when the water level is high), thereby reducing the amount of water used. It is suppressed.
なお、給水ユニット１２Ｂは、給水ホース接続口４と接続され、各給水電磁弁１２ｍ、１２ｎ、１２ｏ、１２ｐの開閉によって、水道水が適切な位置を流れるように給水経路ユニットが構成されている。 The water supply unit 12B is connected to the water supply hose connection port 4, and the water supply path unit is configured such that tap water flows through an appropriate position by opening and closing the water supply electromagnetic valves 12m, 12n, 12o, and 12p.
第２実施形態における給水経路は、第１実施形態と同様に、水路部材５０と外槽カバー９ａによって構成され、例えば、水路部材５０の底面５０ａに底面側散水口５０ａ１が周方向に沿って間隔を置いて形成されたものである。 The water supply path in 2nd Embodiment is comprised by the water channel member 50 and the outer tank cover 9a similarly to 1st Embodiment, for example, the bottom surface side sprinkling port 50a1 is spaced along the circumferential direction at the bottom surface 50a of the water channel member 50. Is formed.
図１４に示すように、水路部材５０は、底面側散水口５０ａ１と、洗濯兼脱水槽８の外周縁部上面８ｃ１とが対向するように配置されている。これにより、底面側散水口５０ａ１から散水された水道水は、実線矢印で示すように、洗濯兼脱水槽８の上部（バランスリング８ｃの外周縁部上面８ｃ１）に直接的に散水される。このとき、洗濯兼脱水槽８が回転することで、洗濯兼脱水槽８の回転時の遠心力によって水道水が外槽９の内周面９ｓに飛散する。外槽９の内周面９ｓに降りかかった水道水は、重力の作用によって鉛直方向下方に向けて流れ落ちる。これにより、外槽９の内周面９ｓに付着した汚れやゴミが取り除かれ、また内周面９ｓに汚れやゴミが付着するのを抑制することができる。 As shown in FIG. 14, the water channel member 50 is disposed so that the bottom surface side water spout 50 a 1 and the outer peripheral edge upper surface 8 c 1 of the washing and dewatering tub 8 face each other. Thereby, the tap water sprinkled from the bottom surface side sprinkling port 50a1 is directly sprinkled on the upper part of the washing and dewatering tub 8 (the outer peripheral edge upper surface 8c1 of the balance ring 8c) as indicated by the solid line arrow. At this time, the washing and dewatering tub 8 is rotated, so that tap water is scattered on the inner peripheral surface 9 s of the outer tub 9 by the centrifugal force when the washing and dewatering tub 8 is rotated. The tap water that has fallen on the inner peripheral surface 9s of the outer tub 9 flows down downward in the vertical direction by the action of gravity. Thereby, the dirt and dust adhering to the inner peripheral surface 9s of the outer tub 9 can be removed, and the dirt and dust adhering to the inner peripheral surface 9s can be suppressed.
また、図１５に示すように、バランスリング８ｃ上縁部に同心円状に設けられた水溜め部８ｃ２に、洗浄ホース１１ｃを介して直接散水してもよい。水溜め部８ｃ２に溜まる水は、洗濯兼脱水槽８が回転時の遠心力によって実線矢印のように外槽９の内周面９ｓに飛散する。外槽９の内周面９ｓに降りかかった水道水は、重力の作用によって鉛直方向下方に向けて流れ落ちる。これにより、外槽９の内周面９ｓに付着した汚れやゴミが取り除かれ、また内周面９ｓに汚れやゴミが付着するのを抑制することができる。 Further, as shown in FIG. 15, water may be directly sprayed to the water reservoir 8c2 provided concentrically on the upper edge of the balance ring 8c via the cleaning hose 11c. The water accumulated in the water reservoir 8c2 is scattered on the inner peripheral surface 9s of the outer tub 9 as indicated by the solid line arrow by the centrifugal force when the washing / dehydrating tub 8 rotates. The tap water that has fallen on the inner peripheral surface 9s of the outer tub 9 flows down downward in the vertical direction by the action of gravity. Thereby, the dirt and dust adhering to the inner peripheral surface 9s of the outer tub 9 can be removed, and the dirt and dust adhering to the inner peripheral surface 9s can be suppressed.
また、内周面９ｓに飛散した水、あるいは水溜め部８ｃから溢れ出した水は、洗濯兼脱水槽８（バランスリング８ｃ）側に向けて飛び散って、洗濯兼脱水槽８の外周面８ｓに付着する。同時に、外周面８ｓに付着した水道水は、洗濯兼脱水槽８の回転時の遠心力と重力の作用によって外周面８ｓを鉛直方向に傾斜しながら下方に向けて流れ落ちる。これにより、洗濯兼脱水槽８の外周面８ｓに付着した汚れやゴミが取り除かれ、また外周面８ｓに汚れやゴミが付着するのを抑制することができる。 Further, the water splashed on the inner peripheral surface 9 s or the water overflowing from the water reservoir 8 c scatters toward the washing / dehydrating tub 8 (balance ring 8 c) side, and reaches the outer peripheral surface 8 s of the washing / dehydrating tub 8. Adhere to. At the same time, the tap water adhering to the outer peripheral surface 8s flows down downward while the outer peripheral surface 8s is inclined in the vertical direction due to the centrifugal force and gravity when the washing and dewatering tub 8 is rotated. Thereby, the dirt and dust adhering to the outer peripheral surface 8s of the washing and dewatering tub 8 can be removed, and the dirt and dust adhering to the outer peripheral surface 8s can be suppressed.
次に、貫通孔８ａ１の位置を工夫し、脱水時の高速運転で吹き飛ばした水で、外槽９の汚れを洗い流す点を、以下説明する。 Next, the point where the through-hole 8a1 is devised and the dirt of the outer tub 9 is washed away with water blown off at high speed during dehydration will be described below.
上述の実施形態における胴板８ａは、その材質としてステンレス鋼などが利用され、具体的には、図１９に示すような構造の板材を円筒状に曲げることにより形成される。この胴板８ａの内壁面には、脱水用の貫通孔８ａ１のほかに、洗濯兼脱水槽８の回転中心に向かって球面状に突出する複数の張出部８ａ３が設けられている。この張出部８ａ３の径は、貫通孔８ａ１の径よりも大きく、各張出部８ａ３の周囲には、貫通孔８ａ１が８個形成され、これら貫通孔８ａ１が張出部８ａ３と同心円上に配置されている。これにより、張出部８ａ３と貫通孔８ａ１との間に水の通り道となる隙間が形成され易くなるので、衣類から脱水された水がこの隙間を通って貫通孔８ａ１へと流れ、脱水性能を高く維持できる。 The body plate 8a in the above-described embodiment uses stainless steel or the like as its material, and specifically, is formed by bending a plate material having a structure as shown in FIG. In addition to the dewatering through hole 8a1, a plurality of overhanging portions 8a3 projecting in a spherical shape toward the rotation center of the washing and dewatering tub 8 are provided on the inner wall surface of the body plate 8a. The diameter of the overhanging portion 8a3 is larger than the diameter of the through hole 8a1, and eight through holes 8a1 are formed around each overhanging portion 8a3, and these through holes 8a1 are concentric with the overhanging portion 8a3. Has been placed. As a result, a gap that becomes a passage for water is easily formed between the overhanging portion 8a3 and the through hole 8a1, so that water dehydrated from the clothing flows into the through hole 8a1 through this gap, and the dewatering performance is improved. Highly maintainable.
また、胴板８ａの周方向の一部には、張出部８ａ３及び貫通孔８ａ１の存在しない領域があり、この領域に複数の補助貫通孔８ａ２が設けられている。この補助貫通孔８ａ２は、胴板８ａの軸方向について、各貫通孔８ａ１の場所とずらして形成されており、各貫通孔８ａ１の間のスペースを埋め合わせる配置となっている。したがって、脱水時の洗濯兼脱水槽８の回転により、貫通孔８ａ１及び補助貫通孔８ａ２から洗濯兼脱水槽８の外周側へ噴出した水が、外槽９の内壁面の軸方向について、上端から下端にかけて万遍なく当たることになる。その結果、外槽９の内壁面の汚れ付着防止効果を、斑無く得ることが可能である。しかも、胴板８ａの周方向の多くを占める領域は、脱水性能を高く維持できるような貫通孔８ａ１及び張出部８ａ３の配置を確保しつつ、胴板８ａの周方向の他の領域に、段違いの補助貫通孔８ａ２を軸方向に重ならないよう複数並べて設けることにより、汚れ付着の防止効果を容易に付加できる。 Further, a part of the body plate 8a in the circumferential direction includes a region where the overhanging portion 8a3 and the through hole 8a1 do not exist, and a plurality of auxiliary through holes 8a2 are provided in this region. The auxiliary through-holes 8a2 are formed so as to be shifted from the positions of the respective through-holes 8a1 in the axial direction of the body plate 8a, and are arranged to make up for the spaces between the respective through-holes 8a1. Therefore, the water spouted from the through hole 8a1 and the auxiliary through hole 8a2 to the outer peripheral side of the washing and dewatering tank 8 due to the rotation of the washing and dewatering tank 8 at the time of dehydration is from the upper end in the axial direction of the inner wall surface of the outer tank 9. It will hit all the way to the bottom. As a result, the effect of preventing the adhesion of dirt on the inner wall surface of the outer tub 9 can be obtained without spots. In addition, the area occupying most of the circumferential direction of the body plate 8a is in other areas in the circumferential direction of the body plate 8a while ensuring the arrangement of the through holes 8a1 and the overhanging portions 8a3 so that the dewatering performance can be maintained high. By providing a plurality of different auxiliary through holes 8a2 arranged side by side so as not to overlap in the axial direction, the effect of preventing the adhesion of dirt can be easily added.
更に、本実施形態の胴板８ａは、図１９の通り、同一形状である第１板部８Ａ１と第２板部８Ａ２とで構成され、各板部の周方向一端及び他端における補助貫通孔８ａ２の配置は、互いに周方向について対称となっている。このため、補助貫通孔８ａ２を同一の型で製造でき、胴板８ａの生産性が高い。 Further, as shown in FIG. 19, the body plate 8a of the present embodiment is composed of a first plate portion 8A1 and a second plate portion 8A2 having the same shape, and auxiliary through holes at one end and the other end in the circumferential direction of each plate portion. The arrangement of 8a2 is symmetrical with respect to the circumferential direction. For this reason, the auxiliary through hole 8a2 can be manufactured in the same mold, and the productivity of the body plate 8a is high.
以上、第１実施形態および第２実施形態に係る洗濯機として、洗濯兼脱水槽８の回転軸が略鉛直方向の縦型式洗濯乾燥機を用いて説明したが、これらに限定されるものではなく、乾燥機能を有しない縦型式洗濯機であってもよい。 As described above, the washing machine according to the first embodiment and the second embodiment has been described by using the vertical type washing and drying machine in which the rotation axis of the washing and dewatering tub 8 is substantially vertical, but is not limited thereto. Further, it may be a vertical washing machine that does not have a drying function.
