Description

【０００１】
【発明の属する技術分野】
本発明は、洗濯兼脱水槽内に入れた洗濯物を洗濯する洗濯機に関するものである。
【０００２】
【従来の技術】
従来、洗濯機は、図３に示すように構成した。以下、その構成について説明する。
【０００３】
図３に示すように、洗濯兼脱水槽１は、内壁面に多数の小穴を有し、底面に攪拌翼２を回転自在に配置し、この洗濯兼脱水槽１の外側に水受け槽３を設けている。水受け槽３の底面には、洗濯兼脱水槽１と攪拌翼２を駆動するモータ（駆動手段）４を取りつけ、駆動部の切り替えを行うクラッチ装置５を介して洗濯兼脱水槽１または攪拌翼２を駆動するように構成している。
【０００４】
水受け槽３は外枠６にサスペンション７を介して防振支持している。洗濯兼脱水槽１の内壁に水路カバー８を固定して循環水路９を形成し、この循環経路９は攪拌翼２の裏面に一体に設けた下側羽根１０の外周に形成したポンプ室１１と洗濯兼脱水槽１の上部のリントフィルター１２との間を連結している。
【０００５】
洗濯兼脱水槽１の上部には、液体を内封した流体バランサー１３を固定し、水受け槽３の上面は水受け槽カバー１４によって覆われている。水受け槽３と水受け槽カバー１４の間にはパッキング部材１５を介在させて、水蜜を確保している。また、水受け槽カバー１４の略中央には内蓋１６を開閉自在に設け、この内蓋１６は水受け槽カバー１４に軸支している。
【０００６】
排水弁１７は水受け槽３内の洗濯水を排水するものであり、給水弁１８は洗濯兼脱水槽１内に給水するものである。制御装置１９はモータ４、排水弁１７、給水弁１８などの動作を制御し、洗い、すすぎ、脱水の一連の行程を逐次制御する。
【０００７】
給水弁１８は水受け槽カバー１４の上部に配置し、給水弁１８からの給水は、水受け槽カバー１４の給水受け部２０に当たり、拡散されて、給水受け部２０の貫通穴２１から洗濯兼脱水槽１内に給水するよう構成している。
【０００８】
水受け槽３には、排水弁１７を介して排水経路２２を接続するとともに、水受け槽カバー１４には、給水受け部２０の後方に水回収壁２３を上方に向けて立設し、水受け槽３の外周近傍部に排水経路２２に連通する溢水排水経路２４を設けている。
【０００９】
上記構成において動作を説明すると、洗濯兼脱水槽１内に洗濯物を入れ、給水弁１８をオンすると、給水弁１８から給水される水は、水受け槽カバー１４の給水受け部２０に当たり、拡散されて給水受け部２０の貫通穴２１から洗濯兼脱水槽１内に給水される。このとき、水受け槽カバー１４の給水受け部２０で水の飛び散りが発生しても、給水受け部２０の後方に立設した水回収壁２３により、阻止されて溢水排水経路２４より排水経路２２を通って排水され、床面への滴下、あるいは水受け槽３からの溢水による床面への水溢れなどをなくすることができる。
【００１０】
所定の水位まで給水した後は、洗濯兼脱水槽１に投入した洗濯物（衣類）を攪拌翼２によって攪拌し、洗濯液を洗濯物に侵透させ、かつ洗濯物を揉むことで汚れを除去する。すすぎ行程では、水受け槽３に水を入れて、攪拌翼２によって攪拌して洗濯物をすすぐ。脱水行程では、クラッチ装置５を切り替えて、モータ４の回転を洗濯兼脱水槽１に伝達し、洗濯兼脱水槽１を回転することで洗濯物の水分を遠心脱水する。
【００１１】
【発明が解決しようとする課題】
このような従来の構成では、洗濯兼脱水槽１内に洗濯物を入れ、給水弁１８をオンして給水したとき、給水弁１８から給水される水は、水受け槽カバー１４の給水受け部２０に当たり、拡散されて給水受け部２０の貫通穴２１から洗濯兼脱水槽１内に給水される。このとき、水道水圧が高い場合など給水弁１８からの給水の勢いが強い場合には、給水受け部２０に当たり、周囲に飛び散って、給水受け部２０の後方に立設した水回収壁２３を越えて床面に滴下する可能性があり、また、給水弁１８が故障した場合には、給水弁１８から水が出っぱなしとなり、床面へ溢れ出る可能性があるという問題を有していた。
【００１２】
また、洗濯兼脱水槽１を洗濯液の中で回転させると、回転による遠心力で水受け槽３の内面を洗濯液がせり上がり、上昇した洗濯液は上部の水受け槽カバー１４で方向を変えて、洗濯兼脱水槽１と水受け槽カバー１４の間から洗濯兼脱水槽１の略回転中心に向けて吐出される。このとき、洗濯液は水受け槽カバー１４にぶつかり方向変えるために水圧を受けることになる。このとき、水受け槽カバー１４の給水受け部２０の貫通穴２１より直接水が噴き出し、床面への水の飛び散りなどがあるという問題を有していた。
【００１３】
本発明は上記従来の課題を解決するもので、給水弁から給水時の水受け槽カバーの給水受け部からの水の飛び散りによる床面滴下、または給水弁の故障による水受け槽からの溢水による床面への水溢れなどをなくし、さらに、水受け槽カバーの給水受け部の貫通穴より直接水が噴き出すのを防止し、床面への水の飛び散りなどをなくし、安全性を向上することを目的としている。
【００１４】
【課題を解決するための手段】
本発明は上記目的を達成するために、水受け槽内に回転自在に配設した洗濯兼脱水槽を駆動手段により駆動し、水受け槽の上方を複数個の貫通穴を配設した給水受け部を有する水受け槽カバーにより覆い、給水受け部への給水を給水弁により制御し、水受け槽カバーの略中央で給水受け部の前方側に内蓋が開閉自在に水受け槽カバーに軸支され、水受け槽に排水弁を介して排水経路を接続するとともに、水受け槽の外周近傍に排水弁の下流側の排水経路に連通する溢水排水経路を設け、制御装置により駆動手段、給水弁および排水弁等を制御し洗い、すすぎ脱水の一連の行程を逐次制御し、制御装置は、洗い、すすぎの各行程で、洗濯兼脱水槽を所定回転速度で回転させることで、前記洗濯兼脱水槽内の洗濯液を前記洗濯兼脱水槽と水受け槽の間に移動させるとともに、前記洗濯兼脱水槽と水受け槽の間の洗濯液を前記洗濯兼脱水槽と水受け槽カバーの間から前記洗濯兼脱水槽の略回転中心に向けて吐出させることで、洗濯液が循環するようにした洗濯機であって、水受け槽カバーには給水受け部の後方に水回収壁を上方に向けて立設し、水回収壁は、溢水排水経路に向かって溢水を誘導するように構成するとともに、給水受け部に設けた複数個の貫通穴のうち最も外側に位置する一列の貫通穴の上方には、屋根状の遮蔽壁を設けものである。
【００１５】
これにより、洗濯兼脱水槽を洗濯液の中で回転させると、回転による遠心力で水受け槽の内面を洗濯液がせり上がり、上昇した洗濯液は上部の水受け槽カバーで方向を変えて、洗濯兼脱水槽と水受け槽カバーの間から洗濯兼脱水槽の略回転中心に向けて吐出し、このとき、洗濯液は水受け槽カバーにぶつかり方向変えるために水圧を受けることになるが、水受け槽カバーの給水受け部の貫通穴の屋根状の遮蔽壁により、直接水が噴き出すことがなく、床面への水の飛び散りなどをなくすことができる。
【００１６】
【発明の実施の形態】
本発明の請求項１に記載の発明は、水受け槽内に回転自在に配設した洗濯兼脱水槽と、前記洗濯兼脱水槽を駆動する駆動手段と、前記水受け槽の上方を覆い複数個の貫通穴を配設した給水受け部を有する水受け槽カバーと、前記給水受け部への給水を制御する給水弁と、前記水受け槽カバーの略中央で前記給水受け部の前方側に開閉自在に設けられ前記水受け槽カバーに軸支された内蓋と、前記水受け槽に排水弁を介して接続された排水経路と、前記水受け槽の外周近傍に設けられ前記排水弁の下流側の前記排水経路に連通する溢水排水経路と、前記駆動手段、給水弁および排水弁等を制御し洗い、すすぎ脱水の一連の行程を逐次制御する制御装置とを備え、前記制御装置は、洗い、すすぎの各行程で、前記洗濯兼脱水槽を所定回転速度で回転させることで、前記洗濯兼脱水槽内の洗濯液を前記洗濯兼脱水槽と前記水受け槽の間に移動させるとともに、前記洗濯兼脱水槽と前記水受け槽の間の洗濯液を前記洗濯兼脱水槽と前記水受け槽カバーの間から前記洗濯兼脱水槽の略回転中心に向けて吐出させることで、洗濯液が循環するようにした洗濯機であって、前記水受け槽カバーには前記給水受け部の後方に水回収壁を上方に向けて立設し、前記水回収壁は、前記溢水排水経路に向かって溢水を誘導するように構成するとともに、前記給水受け部に設けた複数個の貫通穴のうち最も外側に位置する一列の貫通穴の上方には、屋根状の遮蔽壁を設けたものであり、洗濯兼脱水槽を洗濯液の中で回転させると、回転による遠心力で水受け槽の内面を洗濯液がせり上がり、上昇した洗濯液は上部の水受け槽カバーで方向を変えて、洗濯兼脱水槽と水受け槽カバーの間から洗濯兼脱水槽の略回転中心に向けて吐出し、このとき、洗濯液は水受け槽カバーにぶつかり方向変えるために水圧を受けることになるが、水受け槽カバーの給水受け部の貫通穴の屋根状の遮蔽壁により、直接水が噴き出すことがなく、床面への水の飛び散りなどをなくすことができる。
【００１７】
請求項２に記載の発明は、上記請求項１に記載の発明において、水回収壁は、少なくとも給水受け部の後方側に３重に配設したものであり、水道水圧が高い場合など給水弁からの給水の勢いが強い場合に、給水受け部に立設した１つの水回収壁を越えた場合でも、つづいて他の水回収壁を越えることはなく、給水弁から給水時の水受け槽カバーの給水受け部からの水の飛び散りによる床面滴下、または給水弁の故障による水受け槽からの溢水による床面への水溢れなどをなくすることができ、安全性を向上することができる。
【００１８】
請求項３に記載の発明は、上記請求項２に記載の発明において、水受け槽カバーの給水受け部に配設した水回収壁は、少なくとも最も内側に位置する水回収壁を他の水回収壁よりも高く配設したものであり、最も内側に位置する水回収壁を他の水回収壁よりも高くすることにより、水道水圧が高い場合など給水弁からの給水の勢いが強い場合に、水が最初の（最も内側の）水回収壁を越えにくくすることができ、つづいて他の水回収壁を越えることはなく、給水弁から給水時の水受け槽カバーの給水受け部からの水の飛び散りによる床面滴下、または給水弁の故障による水受け槽からの溢水による床面への水溢れなどをなくすることができ、安全性を向上することができる。
【００１９】

【実施例】
以下、本発明の一実施例について、図面を参照しながら説明する。なお、従来例と同じ構成のものは同一符号を付して説明を省略する。
【００２０】
図１および図２に示すように、水受け槽カバー２５は、水受け槽３の上面を覆い、水受け槽３と水受け槽カバー２５の間にはパッキング部材２６を介在させて、水蜜を確保している。また、水受け槽カバー２５の略中央には、開閉自在な内蓋２７を水受け槽カバー２５に軸支している。
【００２１】
水受け槽カバー２５には、給水弁１８からの給水が当たる給水受け部２８を設けており、この給水受け部２８の後方に水回収壁２９を上方に向けて立設し、水受け槽３の外周近傍に排水経路２２に連通する溢水排水経路３０を設け、水回収壁２９は、溢水排水経路３０に向かって溢水を誘導するように構成し、水回収壁２９を少なくとも３重に配設している。また、この３重に配設した水回収壁２９の最も内側に位置する水回収壁２９ａを少なくとも他の水回収壁２９よりも高く構成することにより、溢水条件を良化し、容易に床面に溢れないようにしている。
【００２２】
また、水受け槽カバー２５の給水受け部２８には、洗濯兼脱水槽１内に給水する複数の貫通穴３１を設け、これら貫通穴３１の内、最も外側に位置する１列の貫通穴３１ａには水受け槽カバー２５の上方側に屋根状の遮蔽壁３２を設け、下からの水の飛び出しを規制している。
【００２３】
水受け槽カバー２５の略中央に軸支された内蓋２７の端面３３は、水受け槽カバー２５の給水受け部２８の端面部３４よりも下方に位置し、かつ、内蓋２７の端面３３は給水受け部２８の端面３４と重なり合うように延設している。
【００２４】
そして、傷みやすい洗濯物を洗濯するときは、洗い、すすぎの各行程で、洗濯兼脱水槽１を、たとえば、３００ｒｐｍで回転駆動し、この洗濯兼脱水槽１を回転駆動することによるポンプ作用で、洗濯兼脱水槽１と水受け槽３の間の洗濯液を洗濯兼脱水槽１と水受け槽カバー２５の間から洗濯兼脱水槽１の略回転中心に向けて吐出させる構成としている。
【００２５】
吐出した洗濯液は洗濯物内を通過した後、再び洗濯兼脱水槽１の内壁面に設けた多数の小穴を通して、洗濯兼脱水槽１と水受け槽３の間に移動する経路で循環する。この洗濯液の循環により、洗濯液が洗濯物内を通過するとき、洗濯物の汚れを除去することができる。特に、洗濯兼脱水槽１と水受け槽カバー２５の間から洗濯兼脱水槽１の略回転中心に向けて洗濯液を吐出させるため、洗濯液を洗濯物全体に遠心力で効率的に浸透させることができる。
【００２６】
上記構成において動作を説明すると、洗濯兼脱水槽１内に洗濯物を入れ、給水弁１８をオンして給水すると、給水された水は水受け槽カバー２５の給水受け部２８に当たり、拡散され給水される。このとき、給水受け部２８の後方側の水回収壁２９を３重に配設することにより、水道水圧が高い場合など給水弁１８からの給水の勢いが強い場合に、給水受け部２８に立設した水回収壁２９を越えた場合でも、つづいて他の水回収壁２９を越えることはなく、給水弁１８から給水時の水受け槽カバー２５の給水受け部２８からの水の飛び散りによる床面滴下、または給水弁１８の故障による水受け槽３からの溢水による床面への水溢れなどをなくすることができ、安全性を向上することができる。
【００２７】
また、水受け槽カバー２５の給水受け部２８の３重に配設された水回収壁２９は、少なくとも最も内側に位置する水回収壁２９ａを他の水回収壁２９よりも高く配設しているので、水道水圧が高い場合など給水弁１８からの給水の勢いが強い場合に、水が最も内側の水回収壁２９ａを越えにくくすることができ、つづいて他の水回収壁２９を越えることはなく、給水弁１８から給水時の水受け槽カバー２５の給水受け部２８からの水の飛び散りによる床面滴下、または給水弁１８の故障による水受け槽３からの溢水による床面への水溢れなどをなくすることができ、安全性を向上することができる。
【００２８】
また、洗濯兼脱水槽１を洗濯液の中で回転させると、回転による遠心力で水受け槽３の内面を洗濯液がせり上がり、上昇した洗濯液は上部の水受け槽カバー２５で方向を変えて、洗濯兼脱水槽１と水受け槽カバー２５の間から洗濯兼脱水槽１の略回転中心に向けて吐出される。このとき、洗濯液は水受け槽カバー２５にぶつかり方向変えるために水圧を受けることになる。
【００２９】
このとき、水受け槽カバー２５の給水受け部２８には複数個の貫通穴３１を配設し、最も外側に位置する一列の貫通穴３１ａには、水受け槽カバー２５の上方側に屋根状の遮蔽壁３２を設けているので、屋根状の遮蔽壁３２により直接水が噴き出さず、床面への水の飛び散りなどをなくすることができる。したがって、洗濯兼脱水槽１内の洗濯物に攪拌翼２などによる機械力を加えることなく、洗濯液を循環させることで、洗濯物を傷めたり、絡んだりすることなく洗濯でき、さらにこの洗濯による水の噴き出し、水の飛び散り等の心配のない洗濯を行うことができる。
【００３０】
また、水受け槽カバー２５には、略中央部に開閉自在な内蓋２７を軸支し、水受け槽カバー２５の給水受け部２８と相対した内蓋２７の端面３３を給水受け部２８の端面３４より下方に配設しているので、給水時の水がスムースに洗濯兼脱水槽１内に流れ込み、また、内蓋２７の端面３３を下方に位置することで、洗濯物が押しつけられ、洗濯時の洗濯物の回転による布の噛み込みを解消することができる。したがって、給水時の水の飛び散り、あるいは、洗濯物を傷めたり、絡めたりすることなく洗濯することができる。
【００３１】
また、水受け槽カバー２５の給水受け部２８と相対した内蓋２７の端面３３は、給水受け部２８の端面３４より下方に配設するとともに、内蓋２７の端面３３を水受け槽カバー２５の給水受け部２８の端面３３と略重なり合うように配設しているので、給水時の水が一層スムースに洗濯兼脱水槽１内に流れ込み、また、内蓋２７の端面３３を重ならすことで、洗濯物が押しつけられ、洗濯時の洗濯物の回転による布の噛み込みを一層解消することができる。よって給水時の水の飛び散り、あるいは、洗濯物を傷めたり、絡めたりすることなく洗濯することができる。
【００３２】

Provided. A motor (driving means) 4 for driving the washing / dehydrating tub 1 and the agitating blade 2 is attached to the bottom surface of the water receiving tub 3, and the washing / dehydrating tub 1 or the agitating blade is connected via a clutch device 5 for switching the drive unit. 2 is driven.
[0004]
The water receiving tank 3 is supported by the outer frame 6 via a suspension 7 for vibration isolation. A water channel cover 8 is fixed to the inner wall of the washing and dewatering tank 1 to form a circulation water channel 9, and this circulation channel 9 includes a pump chamber 11 formed on the outer periphery of the lower blade 10 integrally provided on the back surface of the stirring blade 2. The upper part of the washing and dewatering tub 1 is connected to the lint filter 12.
[0005]
A fluid balancer 13 enclosing a liquid is fixed to the upper part of the washing and dewatering tank 1, and the upper surface of the water receiving tank 3 is covered with a water receiving tank cover 14. A packing member 15 is interposed between the water receiving tank 3 and the water receiving tank cover 14 to ensure nectar. Further, an inner lid 16 is provided at an approximately center of the water receiving tank cover 14 so as to be freely opened and closed. The inner lid 16 is pivotally supported by the water receiving tank cover 14.
[0006]
The drain valve 17 drains the washing water in the water receiving tub 3, and the water supply valve 18 feeds water into the washing and dewatering tub 1. The control device 19 controls the operation of the motor 4, the drain valve 17, the water supply valve 18, etc., and sequentially controls a series of steps of washing, rinsing and dewatering.
[0007]
The water supply valve 18 is disposed on the upper part of the water receiving tank cover 14, and the water supplied from the water receiving valve 18 hits the water receiving part 20 of the water receiving tank cover 14, is diffused, and is washed from the through hole 21 of the water receiving part 20. The dehydration tank 1 is configured to supply water.
[0008]
A drainage path 22 is connected to the water receiving tank 3 via a drain valve 17, and a water recovery wall 23 is erected on the water receiving tank cover 14 at the rear of the water supply receiving part 20 so as to An overflow drainage path 24 communicating with the drainage path 22 is provided in the vicinity of the outer periphery of the receiving tank 3.
[0009]
The operation in the above configuration will be described. When the laundry is put in the washing and dewatering tank 1 and the water supply valve 18 is turned on, the water supplied from the water supply valve 18 hits the water supply receiving portion 20 of the water receiving tank cover 14 and diffuses. Then, water is supplied from the through hole 21 of the water supply receiving portion 20 into the washing and dewatering tub 1. At this time, even if water splashes occur in the water supply receiving portion 20 of the water receiving tank cover 14, it is blocked by the water recovery wall 23 erected at the rear of the water supply receiving portion 20 and discharged from the overflow drainage route 24. The water is drained through the water, and dripping onto the floor or overflowing of the floor due to overflow from the water receiving tank 3 can be eliminated.
[0010]
After supplying water to a predetermined water level, the laundry (clothing) put into the washing and dewatering tub 1 is agitated by the agitating blade 2 to permeate the laundry into the laundry, and the dirt is removed by massaging the laundry. To do. In the rinsing step, water is poured into the water receiving tub 3 and the laundry is rinsed by stirring with the stirring blade 2. In the dehydration process, the clutch device 5 is switched to transmit the rotation of the motor 4 to the washing / dehydrating tub 1, and by rotating the washing / dehydrating tub 1, the moisture of the laundry is centrifugally dehydrated.
[0011]
[Problems to be solved by the invention]
In such a conventional configuration, when the laundry is put in the washing and dewatering tub 1 and the water supply valve 18 is turned on to supply water, the water supplied from the water supply valve 18 is supplied to the water supply receiving portion of the water receiving tub cover 14. 20 is diffused and supplied into the washing and dewatering tub 1 through the through hole 21 of the water supply receiving portion 20. At this time, when the momentum of the water supply from the water supply valve 18 is strong, such as when the tap water pressure is high, the water hits the water supply receiving portion 20 and scatters to the surroundings and passes over the water collection wall 23 standing behind the water supply receiving portion 20. In the case where the water supply valve 18 breaks down, there is a problem that water may continue to flow out of the water supply valve 18 and overflow to the floor surface. .
[0012]
Further, when the washing and dewatering tub 1 is rotated in the washing liquid, the washing liquid rises on the inner surface of the water receiving tub 3 by the centrifugal force caused by the rotation, and the rising washing liquid is directed in the upper water receiving tub cover 14. Instead, it is discharged from between the washing / dehydrating tub 1 and the water receiving tub cover 14 toward the substantial rotation center of the washing / dehydrating tub 1. At this time, the washing liquid is subjected to water pressure to collide with the water receiving tank cover 14 and change the direction. At this time, there was a problem that water directly spouted out from the through hole 21 of the water supply receiving portion 20 of the water receiving tank cover 14 and the water was scattered on the floor surface.
[0013]
The present invention solves the above-mentioned conventional problems, and is caused by dripping of the floor surface due to water splashing from the water receiving portion of the water receiving tank cover during water supply from the water supply valve, or overflow from the water receiving tank due to a failure of the water supply valve. To prevent water overflowing on the floor, and to prevent water from directly spraying out from the through hole in the water supply receiving part of the water receiving tank cover, thereby eliminating water splashing on the floor and improving safety. It is an object.
[0014]
[Means for Solving the Problems]
In order to achieve the above object, the present invention drives a washing and dewatering tub rotatably disposed in a water receiving tub by a driving means, and a water receiving basin having a plurality of through holes disposed above the water receiving tub. The water receiving tank cover is covered with a water receiving tank cover, and water supply to the water receiving tank is controlled by a water supply valve. The inner lid can be opened and closed in front of the water receiving tank at the approximate center of the water receiving tank cover. is supported, with connecting drainage path through the drain valve in the water receiving tank, the overflow drainage path communicating the drain path of the downstream side of the drain valve near the outer periphery of the water tub provided, the drive means by the control device, the water supply Control and wash the valve and drain valve, etc., and sequentially control a series of processes of rinsing and dehydration, and the controller rotates the washing and dehydrating tank at a predetermined rotational speed in each of the washing and rinsing processes, thereby The washing liquid in the dewatering tub is used as the washing / dehydrating tub and water receiving tub. And moving the washing liquid between the washing / dehydrating tub and the water receiving tub from between the washing / dehydrating tub and the water receiving tub cover toward the rotation center of the washing / dehydrating tub. The washing machine is configured to circulate the washing liquid, and the water receiving tank cover is provided with a water recovery wall facing upward at the rear of the water supply receiving portion, and the water recovery wall is directed toward the overflow drainage path. In addition to being configured to induce overflow , a roof-like shielding wall is provided above a row of through holes located on the outermost side among the plurality of through holes provided in the water supply receiving portion .
[0015]
As a result, when the washing / dehydrating tub is rotated in the washing liquid, the washing liquid rises on the inner surface of the water receiving tub by the centrifugal force of the rotation, and the rising washing liquid changes direction with the upper water receiving tub cover. The water is discharged from between the washing / dehydrating tub and the water receiving tub cover toward the rotation center of the washing / dehydrating tub.
