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４に示すような構成をしていた。以下、その構成について説明する。
【０００３】
図４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。
【０００６】
排水弁１５は水受け槽３内の洗濯水を排水するものである。上部枠体１６の後部パネル１７の内部には洗濯兼脱水槽１内への給水を行う給水弁１８を設け、上部枠体１６の前部パネル１９の内部に制御装置２０を設け、この制御装置２０はモータ４、排水弁１５、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】
上部枠体１６の後部パネル１７には、風呂の残り湯などを給水する給水ポンプ（図示せず）からの給水ホース２１の先端に取り付けた中空の継ぎ手２２が着脱可能な略円筒状の接続ジョイント部２３を一体に設けている。後部パネル１７の内部には中空の風呂水給水路２４を形成し、この風呂水給水路２４は、一方は接続ジョイント部２３にシール接続され、他方は洗濯兼脱水槽１の上部開口部上に開口している。
【０００８】
水受け槽３には、排水弁１５を介して排水径路２５を接続するとともに、水受け槽カバー１４には、水受け槽３の外周近傍部に排水径路２５に連通する溢水排水径路２６を設けている。
【０００９】
上記構成において動作を説明すると、風呂の残り湯を用いて洗濯する場合、給水ポンプの給水ホース２１の先端に取り付けた中空の継ぎ手２２を略円筒状の接続ジョイント部２３に装着し、洗濯兼脱水槽１内に洗濯物を入れ、給水ポンプをオンすると、風呂の残り湯は、給水ポンプ、給水ホース２１、中空の継ぎ手２２、接続ジョイント部２３、風呂水給水路２４を介して、洗濯兼脱水槽１内に給水される。
【００１０】
所定の水位まで給水された後は、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】
また、風呂水の給水時、給水ポンプを止め忘れた場合、給水された風呂水は、水受け槽カバー１４に設けた溢水排水径路２６を通り、排水径路２５を介して、外部に排水される。
【００１２】
【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、給水ポンプからの給水ホース２１の先端に取り付けた中空の継ぎ手２２を接続する接続ジョイント部２３は、後部パネル１７に設けているため、後部パネル１７の内部に、中空の風呂水給水路２４が必要となる。また、後部パネル１７の内部には給水弁１８などの電装部品を内蔵しているため、接続ジョイント部２３と中空の風呂水給水路２４のシール構造や中空の風呂水給水路２４自身のシール性が必要となり、コストが高いものになっていた。また、万一、シール性が損われた場合、電装部品に水がかかる可能性があり、安全上不安定なものとな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、後部パネルの内部に、給水ポンプから給水する際の風呂水給水路やシール構造を設ける必要をなくしてコストを低減し、かつ電装部品に水がかかる可能性をなくし、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、外枠の上部に配設した上部枠体の内部に給水弁を設け、水受け槽を外枠に防振支持し、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、水受け槽の上方を略中央に開閉自在な内蓋を後方で軸支する水受け槽カバーにより覆い、給水弁からの給水が当たり洗濯兼脱水槽内に落下する給水受け部を内蓋の後方側の水受け槽カバーに設け、この給水受け部には、凹部を設け、凹部の底部には、給水ポンプの給水ホースの先端に取り付けた中空の継ぎ手が上方より爪嵌合にて着脱可能に接続される略円筒状の接続ジョイント部を設けたものである。
【００１５】
これにより、後部パネルの内部に、給水ポンプから給水する際の風呂水給水路やシール構造を設ける必要がなくなるため、コストを低減することができ、かつ電装部品に水がかかる可能性をなくすることができ、安全性を向上することができる。
【００１６】
【発明の実施の形態】
本発明の請求項１に記載の発明は、外枠と、前記外枠の上部に配設され内部に給水弁を設けた上部枠体と、前記外枠に防振支持された水受け槽と、前記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略中央に開閉自在な内蓋を後方で軸支する水受け槽カバーと、前記内蓋の後方側の前記水受け槽カバーに設けられ前記給水弁からの給水が当たり前記洗濯兼脱水槽内に落下する給水受け部とを備え、前記給水受け部には、凹部を設け、前記凹部の底部には、給水ポンプの給水ホースの先端に取り付けた中空の継ぎ手が上方より爪嵌合にて着脱可能に接続される略円筒状の接続ジョイント部を設けたものであり、上部枠体の後部パネルの内部に、給水ポンプから給水する際の風呂水給水路やシール構造を設ける必要がなくなるため、コストを低減することができ、かつ電装部品に水がかかる可能性をなくすることができ、安全性を向上することができ、さらに、凹部に接続ジョイント部を設けたことにより、水受け槽カバーと上部枠体の間隔を広くする必要がなく、本体自身を高くする必要がないため、コストを抑えた製品を提供することができる。
【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、凹部の側壁の内、洗濯兼脱水槽の円周方向の側壁を傾斜面とするとともに、前記傾斜面と前記凹部の底部とは曲面でつなぐようにしたものであり、洗濯およびすすぎ時に洗濯兼脱水槽の中の洗濯物が回転し、凹部に当たった場合でも、洗濯兼脱水槽の円周方向の側壁を傾斜面としているため、洗濯物が引っ掛かり回転しないということがなく、洗浄性能およびすすぎ性能の低下を防止することができる。
【００１８】
請求項３に記載の発明は、上記請求項１または２に記載の発明において、略円筒状の接続ジョイント部の内部に、穴部を有する流量抑制リブを一体に設けたものであり、使用者が、給水性能が高い給水ポンプを使い風呂水を給水し、給水ポンプを止め忘れた場合でも、給水径路に穴部を有する流量抑制リブを設けているので、給水量を抑制できるため、風呂水が、水受け槽カバーに設けた溢水排水径路から溢れ出し、床面へ水溢れが発生するといったこと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２７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２７の間にはパッキング部材２８を介在させて、水密を確保している。また、水受け槽カバー２７の略中央には、開閉自在な内蓋２９を軸支している。
【００２１】
水受け槽カバー２７には、給水弁１８からの給水が当たる給水受け部３０を設けており、この給水受け部３０の後方に水回収壁３１を上方に向けて立設し、水受け槽３の外周近傍に排水径路２５に連通する溢水排水径路３２を設け、水回収壁３１は、溢水排水径路３２に向かって溢水を誘導するように構成し、水回収壁３１を複数本配設している。
【００２２】
また、水受け槽カバー２７の給水受け部３０には、凹部３３を設け、その凹部３３の略中央の底部３３ａには、給水ポンプ（図示せず）からの給水ホース３４の先端に取り付けた中空の継ぎ手３５が着脱可能な略円筒状の接続ジョイント部３６を設けている。
【００２３】
つぎに、図３に示すように、接続ジョイント部３６を設けた凹部３３の洗濯兼脱水槽１の円周方向の側壁３３ｂはなだらかな傾斜面となっている。また円周方向の側壁３３ｂと底部３３ａはなだらかな曲面でつないでいる。接続ジョイント部３６の外壁には外径方向に扇状リブ３７を設けており、この扇状リブ３７と継ぎ手３５の爪部３８とを嵌合させ、継ぎ手３５を接続ジョイント部３６に取り付けている。また、接続ジョイント部３６の円筒内部には、穴部３９を有する流量抑制リブ４０を設けている。
【００２４】
上記構成において動作を説明すると、風呂の残り湯を用いて洗濯する場合、給水ポンプの給水ホース３４の先端に取り付けた中空の継ぎ手３５を略円筒状の接続ジョイント部３６に装着し、洗濯兼脱水槽１内に洗濯物を入れ、給水ポンプをオンすると、風呂の残り湯は、給水ポンプ、給水ホース３４、中空の継ぎ手３５、接続ジョイント部３６を介して、洗濯兼脱水槽１内に給水される。
【００２５】
この際、中空の継ぎ手３５、接続ジョイント部３６の水密性は問題とならず、仮に中空の継ぎ手３５、接続ジョイント部３６間で水が漏れた場合でも、水は水受け槽カバー２７上に流れ、洗濯兼脱水槽１内に落下するだけであり、近傍に電装部品などがないため、電装部品などに水がかかる心配もない。
【００２６】
また、凹部３３の洗濯兼脱水槽１の円周方向の側壁３３ｂはなだらかな傾斜面となっており、円周方向の側壁３３ｂと底部３３ａはなだらかな曲面でつないでいるため、洗濯およびすすぎ時に洗濯兼脱水槽１の中の洗濯物が回転し、凹部３３に当たった場合でも、洗濯物が引っ掛かり回転しないということがなく、洗浄性能およびすすぎ性能の低下を防止することができる。
【００２７】
さらに、接続ジョイント部３６の円筒内部には、穴部３９を有する流量抑制リブ４０を設けているため、給水性能が高い給水ポンプを使い風呂水を給水し、給水ポンプを止め忘れた場合でも、給水ポンプの給水量を適量に抑制できるため、風呂水が、水受け槽カバー１４に設けた溢水排水径路２６から溢れ出し、床面へ水溢れが発生するといったこと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】
【発明の効果】
以上のように本発明の請求項１に記載の発明によれば、外枠と、前記外枠の上部に配設され内部に給水弁を設けた上部枠体と、前記外枠に防振支持された水受け槽と、前記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略中央に開閉自在な内蓋を後方で軸支する水受け槽カバーと、前記内蓋の後方側の前記水受け槽カバーに設けられ前記給水弁からの給水が当たり前記洗濯兼脱水槽内に落下する給水受け部とを備え、前記給水受け部には、凹部を設け、前記凹部の底部には、給水ポンプの給水ホースの先端に取り付けた中空の継ぎ手が上方より爪嵌合にて着脱可能に接続される略円筒状の接続ジョイント部を設けたから、上部枠体の後部パネルの内部に、給水ポンプから給水する際の風呂水給水路やシール構造を設ける必要がなくなるため、コストを低減することができ、かつ電装部品に水がかかる可能性をなくすることができ、安全性を向上することができ、さらに、凹部に接続ジョイント部を設けたことにより、水受け槽カバーと上部枠体の間隔を広くする必要がなく、本体自身を高くする必要がないため、コストを抑えた製品を提供することができる。
【００２９】
また、請求項２に記載の発明によれば、凹部の側壁の内、洗濯兼脱水槽の円周方向の側壁を傾斜面とするとともに、前記傾斜面と前記凹部の底部とは曲面でつなぐようにしたから、洗濯およびすすぎ時に洗濯兼脱水槽の中の洗濯物が回転し、凹部に当たった場合でも、洗濯兼脱水槽の円周方向の側壁を傾斜面としているため、洗濯物が引っ掛かり回転しないということがなく、洗浄性能およびすすぎ性能の低下を防止することができる。

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.
[0006]
The drain valve 15 drains the washing water in the water receiving tank 3. A water supply valve 18 for supplying water into the washing and dewatering tub 1 is provided inside the rear panel 17 of the upper frame body 16, and a control device 20 is provided inside the front panel 19 of the upper frame body 16. 20 controls the operation of the motor 4, drain valve 15, water supply valve 18 and the like, and sequentially controls a series of steps of washing, rinsing and dehydration.
[0007]
The rear panel 17 of the upper frame 16 has a substantially cylindrical connection joint to which a hollow joint 22 attached to the tip of a water supply hose 21 from a water supply pump (not shown) for supplying remaining hot water of a bath can be attached and detached. The part 23 is provided integrally. A hollow bath water supply channel 24 is formed inside the rear panel 17. One of the bath water supply channels 24 is seal-connected to the connection joint portion 23, and the other is on the upper opening of the washing and dewatering tub 1. It is open.
[0008]

According to the invention described in claim 3 , since the flow rate suppressing rib having the hole portion is integrally provided in the inside of the substantially cylindrical connection joint portion, the user uses a water supply pump having a high water supply performance. Even if water is supplied and the water supply pump is forgotten to stop, the water supply path is provided with a flow control rib that has a hole, so the amount of water supply can be suppressed. It is possible to eliminate the overflow from the path and the occurrence of water overflow to the floor surface, and the safety can be improved.
