（実施の形態１）
図１は、本発明の実施の形態におけるドラム式洗濯機の縦断面図を示すものである。 (Embodiment 1)
FIG. 1 shows a longitudinal sectional view of a drum type washing machine in an embodiment of the present invention.

図１において、洗濯機筺体４１の内部に揺動自在に水槽４２が配設され、水槽４２内には、回転ドラム４３が回転自在に配設されている。回転ドラム４３の回転中心に水平方向に回転軸（回転中心軸）４４が設けられ、この回転軸４４に、水槽４２の背面側近傍に取り付けたモータ４５が、ベルト４６を介して連結され、モータ４５により回転ドラム４３が正転、逆転方向に回転駆動される。回転ドラム４３の内壁面には、洗濯物を撹拌するための数個の突起板４７が設けられている。また、回転ドラム４３の外周部には、多数の通水孔４８が全面に設けられている。 In FIG. 1, a water tank 42 is swingably disposed inside a washing machine housing 41, and a rotating drum 43 is rotatably disposed in the water tank 42. A rotation shaft (rotation center shaft) 44 is provided in the horizontal direction at the rotation center of the rotating drum 43, and a motor 45 attached to the rotation shaft 44 in the vicinity of the back side of the water tank 42 is connected via a belt 46. The rotary drum 43 is rotated by 45 in the forward and reverse directions. Several protrusion plates 47 for stirring the laundry are provided on the inner wall surface of the rotating drum 43. In addition, a large number of water passage holes 48 are provided on the entire outer periphery of the rotating drum 43.

上記の、水槽４２、回転ドラム４３、モータ４５等により、振動系の水槽ユニット４９が構成されており、この水槽ユニット４９は、洗濯機筺体４１上部から複数のばね体５０により、また、洗濯機筺体４１下部から複数の防振ダンパー５１により防振支持されている。 The water tank 42, the rotating drum 43, the motor 45, and the like constitute a vibration water tank unit 49. The water tank unit 49 is formed by a plurality of spring bodies 50 from above the washing machine housing 41, and the washing machine. Anti-vibration is supported by a plurality of anti-vibration dampers 51 from the bottom of the housing 41.

また、水槽４２の正面側で洗濯機筺体４１に設けた筺体開口部４０を、蓋体５２により開閉自在に覆い、蓋体５２は、水槽４２前部と筺体開口部４０を連結した防振と水封の役目をするシールパッキング８２を介して密閉し、また開くことができるようにしており、この蓋体５２を開くことにより、衣類出入口５３を通して回転ドラム４３内に洗濯物を出し入れできるようにしている。 Further, the housing opening 40 provided in the washing machine housing 41 on the front side of the water tub 42 is covered with a lid 52 so that the housing 52 can be opened and closed. It is sealed and opened through a seal packing 82 that serves as a water seal. By opening the lid 52, the laundry can be taken in and out of the rotary drum 43 through the clothing entrance 53. ing.

また、このドラム式洗濯機は、モード設定や制御プログラムに従い、モータ４５、給水系５４、排水系５５、水循環系５６を自動制御して、少なくとも洗い行程、すすぎ行程、脱水行程を行う機能を有している。 In addition, this drum type washing machine has a function of automatically controlling the motor 45, the water supply system 54, the drainage system 55, and the water circulation system 56 according to the mode setting and control program to perform at least a washing process, a rinsing process, and a dehydrating process. doing.

給水系５４は、第１の電磁弁５７（第１の給水手段）、あるいは第２の電磁弁５８（第２の給水手段）の開閉によって、第１の給水ホース５９、あるいは第２の給水ホース６０を通り、洗剤や柔軟仕上げ剤を収容し外部から引き出し自在の引き出し部（図示せず）を内部に収納する洗剤収容部６１を介して、給水経路６２から水槽４２内に適時に給水できる。 The water supply system 54 includes a first water supply hose 59 or a second water supply hose by opening and closing the first electromagnetic valve 57 (first water supply means) or the second electromagnetic valve 58 (second water supply means). Water can be supplied from the water supply path 62 into the water tank 42 in a timely manner through the detergent storage 61 that passes through 60 and stores a detergent and a soft finish and stores a drawer (not shown) that can be pulled out from outside.

排水系５５は、排水ポンプ６３の駆動によって、洗い行程終了時、すすぎ行程終了時など必要なときに、水槽４２の底部に接続された排水管６４を介し、糸屑類を捕集し外部から取り外し可能の排水フィルタ６５を通過した後、排水ポンプ６３を通って、機内から機外の上方まで配設された排水ホース６６から排水できるようになっている。 The drainage system 55 collects lint from the outside through the drainage pipe 64 connected to the bottom of the water tank 42 when necessary, such as at the end of the washing process or at the end of the rinsing process, by driving the drainage pump 63. After passing through the detachable drainage filter 65, the drainage hose 66 arranged from the inside of the machine to the upper part outside the machine can be drained through the drainage pump 63.

水循環系５６は、予洗い行程時、洗い行程時、すすぎ行程時など必要に応じ、水槽４２内の水を循環させて、洗剤の早期溶け込みや偏りの防止、洗いやすすぎの機能向上を図る。 The water circulation system 56 circulates the water in the water tank 42 as necessary during the pre-washing process, the washing process, the rinsing process, and the like, thereby preventing the premature dissolution and unevenness of the detergent and improving the function of easy washing.

この水循環系５６は、循環ポンプ６７を駆動させることで、水槽４２内の洗濯水を、排水管６４を介し、排水フィルタ６５を通過させ、循環ポンプ６７への流入側経路６８、循環ポンプ６７および循環ポンプ６７からの吐出側経路６９を介して、水槽４２前面側内方の噴出口７０より実線矢印で示す循環水として回転ドラム４３内に吐出することを繰り返す。なお、噴出口７０は、円周方向に複数設けられ、循環水は円周の全方向から吐出されるようになっている。 The water circulation system 56 drives the circulation pump 67 to pass the washing water in the water tank 42 through the drainage filter 65 via the drainage pipe 64, and the inflow side path 68 to the circulation pump 67, the circulation pump 67 and Through the discharge side path 69 from the circulation pump 67, the water is repeatedly discharged into the rotary drum 43 as the circulating water indicated by the solid line arrow from the inner jet port 70 on the front side of the water tank 42. A plurality of jet outlets 70 are provided in the circumferential direction, and the circulating water is discharged from all directions of the circumference.

また、水槽４２の底部に形成した凹部７１には、洗濯水を加熱するシーズヒータ等からなる温水ヒータ（加熱手段）７２を水平方向に備えており、この温水ヒータ７２により加熱した水槽４２内の洗濯水を、前述のように、回転ドラム４３内に吐出することにより、洗濯水を洗濯物にふりかけて、この洗濯水を、また循環させる。これにより加熱された洗濯水が洗濯物にふりかけられる為、洗濯水の分子活動が高まり、また洗剤の活性化が高まるので、洗浄力を高め、かつ洗いムラを少なくする事ができる。また、温水ヒータ７２近傍には、水温を検知するサーミスタ等の温度検知手段７３が設けられている。 The recess 71 formed at the bottom of the water tank 42 is provided with a hot water heater (heating means) 72 such as a sheathed heater for heating the washing water in the horizontal direction. By discharging the washing water into the rotating drum 43 as described above, the washing water is sprinkled on the laundry and the washing water is circulated again. Since the heated washing water is sprinkled on the laundry, the molecular activity of the washing water is increased and the activation of the detergent is increased, so that the washing power can be increased and washing unevenness can be reduced. In the vicinity of the hot water heater 72, a temperature detection means 73 such as a thermistor for detecting the water temperature is provided.

また、外槽４２の底部外周後方の側壁には、排水管６４と連通してエアートラップ７４を構成し、空気管７５にて、洗濯機筺体４１の上部内方に設けられ、圧力センサなどで構成された水位検知手段７６に連接しており、外槽４２内部に給水された洗濯水の水圧により複数段の水位を検知する事が出来る。 In addition, an air trap 74 is configured on the side wall of the outer periphery of the bottom of the outer tub 42 in communication with the drain pipe 64. The air trap 74 is provided inside the upper portion of the washing machine housing 41 by an air pipe 75, and is provided with a pressure sensor or the like. It is connected to the constructed water level detection means 76, and can detect the water level in a plurality of stages by the water pressure of the washing water supplied into the outer tub 42.

また、洗濯機筺体４１の上部内方に設けられた洗剤収納部６１の後面上部と水槽４２上部とを、連結ホース７７で連結しており、行程運転動作により加圧される水槽４２内の空気を抜く役目をしている。 In addition, the rear upper part of the detergent container 61 provided in the upper part of the washing machine housing 41 and the upper part of the water tank 42 are connected by a connecting hose 77, and the air in the water tank 42 is pressurized by the stroke operation operation. It plays the role of pulling out.

また、水槽４２の上面後部には、水槽ユニット４９の振動を検知する加速度センサの振動検知手段７８が配設されており、１方向の加速度でなく前後（Ｘ軸方向）、左右（Ｙ軸方向）、上下（Ｚ軸方向）の３軸方向の振動を検出し、運転を制御する。これは、実際の水槽ユニット４９の振動は、必ずしも一方向に限定できないので、多軸の加速度センサを用いて、精度高く検知する為である。 In addition, vibration detection means 78 of an acceleration sensor that detects vibration of the water tank unit 49 is disposed on the rear surface of the upper surface of the water tank 42, and is not an acceleration in one direction, but front and rear (X axis direction), left and right (Y axis direction). ), Vibrations in the three axial directions (up and down (Z-axis direction)) are detected to control the operation. This is because the actual vibration of the water tank unit 49 is not necessarily limited to one direction, and is therefore detected with high accuracy using a multi-axis acceleration sensor.

運転コース等のモードや各種機能の選択は、洗濯機筺体４１の前面上部に設けられた操作表示手段７９から使用者が入力設定手段８０へ入力して行い、洗濯機筺体４１の上部内方に配設された制御装置８１が、その入力情報を基に操作パネル７９上の表示手段８３（図２参照）で表示して使用者に知らせる。 The mode such as the driving course and various functions are selected by the user by inputting to the input setting means 80 from the operation display means 79 provided at the upper front of the washing machine housing 41, and inside the upper portion of the washing machine housing 41. The arranged control device 81 is displayed on the display means 83 (see FIG. 2) on the operation panel 79 based on the input information to notify the user.

図２は、本発明の実施の形態におけるドラム式洗濯機の正面図である。 FIG. 2 is a front view of the drum type washing machine in the embodiment of the present invention.

図２において、蓋体５２は、蓋把手８４に手を掛けて開動作を行なうと、左端部に鉛直方向に配設された回転支持部８５を中心に、洗濯機筺体４１の反対側に回動して開けられる。 In FIG. 2, when the lid 52 is opened by placing the hand on the lid handle 84, the lid 52 is rotated to the opposite side of the washing machine housing 41 around the rotation support portion 85 disposed in the vertical direction at the left end portion. Move and open.

図３は、本発明の実施の形態におけるドラム式洗濯機の要部斜視図である。 FIG. 3 is a perspective view of an essential part of the drum type washing machine in the embodiment of the present invention.

図３において、洗濯機筺体４１には、上下に一対のＬ字状連結部８６（Ｌ字状は正確に９０度でなくてもよい）を立設した連結部材８７が固着されており、このＬ字状連結部８６に回転支持部８５が形成されている。蓋体５２には、このＬ字状連結部８６に対応する位置に、外周側に開放する略コ字状の蓋枠切欠き部（切欠き部）８８が形成され、蓋体５２を閉じた時に、この蓋枠切欠き部８８にＬ字状連結部８６が納まるようになっており、蓋体５２を開ける時に、この蓋枠切欠き部８８により開き角度を大きくすることができる。また、連結部材８７の一対のＬ字状連結部８６には、水平方向に一対の角穴部（丸穴部でもよい）８９が形成されており、蓋体５２を開けた時に、この角穴部８９の内面がストッパーになっている（図４、図５で後述）。 In FIG. 3, a connecting member 87 having a pair of upper and lower L-shaped connecting portions 86 (the L shape need not be exactly 90 degrees) is fixed to the washing machine housing 41. A rotation support portion 85 is formed on the L-shaped connection portion 86. The lid body 52 is formed with a substantially U-shaped lid frame notch portion (notch portion) 88 opened to the outer peripheral side at a position corresponding to the L-shaped connecting portion 86, and the lid body 52 is closed. In some cases, the L-shaped connecting portion 86 is accommodated in the lid frame notch 88, and the opening angle can be increased by the lid frame notch 88 when the lid 52 is opened. The pair of L-shaped connecting portions 86 of the connecting member 87 are formed with a pair of square hole portions (or round hole portions) 89 in the horizontal direction, and when the lid body 52 is opened, these square holes are formed. The inner surface of the part 89 is a stopper (described later in FIGS. 4 and 5).

図４は、本発明の実施の形態におけるドラム式洗濯機の蓋体５２が閉状態の要部断面図、図５は、同蓋体５２が開状態の要部断面図である。 FIG. 4 is a cross-sectional view of the main part of the drum type washing machine according to the embodiment of the present invention with the lid 52 closed, and FIG. 5 is a cross-sectional view of the main part with the lid 52 open.

図４、図５において、蓋体５２は、連結部材８７で連結される円周状の蓋枠９０、内蓋９１、外蓋９２、蓋カバー９３で構成されている。 4 and 5, the lid body 52 includes a circumferential lid frame 90, an inner lid 91, an outer lid 92, and a lid cover 93 that are coupled by a coupling member 87.

蓋枠９０は、略リング状で、連結部材８７と連通する回転支持部８５が形成され、内方側に硬質透明材の内蓋９１が挟着されている。蓋体５２が閉状態の時には、この内蓋９１にシールパッキング８２が当接して、水封状態を保っている。また、この蓋枠９０に、図３で前述の外周側に開放するコ字状の蓋枠切欠き部８８が形成されている。 The lid frame 90 is substantially ring-shaped, and is formed with a rotation support portion 85 that communicates with the connecting member 87, and an inner lid 91 made of a hard transparent material is sandwiched on the inner side. When the lid 52 is in a closed state, the seal packing 82 is in contact with the inner lid 91 to maintain a water-sealed state. The lid frame 90 is formed with a U-shaped lid frame notch 88 that opens to the outer peripheral side described above in FIG.

外蓋９２は、蓋枠９０の外方側全体を覆う透明材の円状であり、その外周部外方側を覆うように略リング状の蓋カバー９３が嵌着されている。また、外蓋９２の回転支持部８５側の外周縁内方側には、蓋枠切欠き部８８の開放側に向かって一対の爪部９４が延設されている。 The outer lid 92 has a circular shape made of a transparent material that covers the entire outer side of the lid frame 90, and a substantially ring-shaped lid cover 93 is fitted to cover the outer side of the outer peripheral portion. In addition, a pair of claw portions 94 are extended toward the opening side of the lid frame notch 88 on the inner side of the outer peripheral edge of the outer lid 92 on the rotation support portion 85 side.

前述のように、蓋体５２の開き角度を大きくするために、外周側に開放するコ字状の蓋枠切欠き部８８が形成されているが、このことにより、蓋体５２が閉状態の時に、この蓋枠切欠き部８８に指が入ると、蓋体５２が開いていく時に挟んでしまう恐れがある。しかし、外蓋９２の外周縁内方側には、蓋枠切欠き部８８の開放側に向かって爪部９４を延設していることにより、洗濯機筺体４１との隙間ａが、爪部９４を設けない場合よりも狭く
なっている。これにより、隙間に指が入って挟まれることは防止される。 As described above, in order to increase the opening angle of the lid body 52, the U-shaped lid frame cutout portion 88 opened to the outer peripheral side is formed, and this causes the lid body 52 to be in a closed state. Sometimes, if a finger enters the cover frame notch 88, the cover body 52 may be pinched when it is opened. However, the claw portion 94 is extended toward the open side of the lid frame notch 88 on the inner side of the outer peripheral edge of the outer lid 92, so that the clearance a between the washing machine housing 41 and the claw portion is reduced. It is narrower than the case where 94 is not provided. This prevents a finger from being caught in the gap.

また、蓋体５２を開けた時に、一対の爪部９４が、連結部材８７の一対のＬ字状連結部８６に形成した一対の角穴部８９に遊嵌し、角穴部８９の内面当接部９５に当接して、蓋体５２の開放が止まるようになっている。なお、蓋体５２は、略１５０度以上開いた時に開放が止まるようになっている。 Further, when the lid 52 is opened, the pair of claws 94 are loosely fitted into the pair of square holes 89 formed in the pair of L-shaped coupling parts 86 of the coupling member 87, and the inner surfaces of the square holes 89 are contacted. The lid 52 is stopped from coming into contact with the contact portion 95. The lid 52 stops opening when it is opened approximately 150 degrees or more.

以上のように、本実施の形態においては、蓋体を構成する蓋枠は、蓋体開閉の回転支持部を形成した連結部材のＬ字状連結部に対応する位置に、外周側に開放する略コ字状の蓋枠切欠き部を形成し、外蓋は、外周縁内方側に、蓋枠切欠き部の開放側に向かって一対の爪部を延設するとともに、蓋体を開状態にした時に、爪部がＬ字状連結部に形成した角穴部に遊嵌して、角穴部の内面当接部に当接することにより、使用者または子供等の付帯者が隙間に指を入れて挟むことが防止でき、安全性を向上させることができるとともに、蓋体を閉じた状態で洗濯機筺体から大きく出っ張ることなく、また、蓋体を大きな角度で開けることができるので洗濯物の投入や取り出しがやりやすく、操作性を向上させることができる。 As described above, in the present embodiment, the lid frame constituting the lid opens to the outer peripheral side at a position corresponding to the L-shaped coupling portion of the coupling member that forms the rotation support portion for opening and closing the lid. A substantially U-shaped lid frame notch is formed, and the outer lid has a pair of claws extending toward the open side of the lid frame notch on the inner side of the outer periphery, and the lid is opened.
