Description

【０００１】
【発明の属する技術分野】
本発明は洗濯兼脱水槽を内包した水受け槽を有する脱水兼用洗濯機に関するものである。
【０００２】
【従来の技術】
従来、この種の脱水兼用洗濯機は図５に示すように構成していた。以下、その構成について説明する。
【０００３】
図に示すように、水受け槽１は、吊り棒２により棒振装置３を介して外枠４の角隅より垂下支持されており、内部に洗濯兼脱水槽５を回転自在に設けている。洗濯脱水槽５は中央内底部にパルセータ６を設け、側壁に水抜き用の多数の小穴７を設けている。水受け槽１の底部に排水弁８を設け、排水ホース９を介して外枠４の外部に連通している。
【０００４】
水受け槽１の底部に補強板１０を取り付け、この補強板１０に減速機構１１、モータ１２などを配設し、減速機構１１とモータ１２との間をベルト１３で連結している。減速機構１１は洗濯時にはパルセータ６を回転駆動し、脱水時には洗濯兼脱水槽５を回転駆動するようにモータ１２の駆動力を伝達する機構を有している。洗濯兼脱水槽５の上部にはバランサー１４を設けている。
【０００５】
上記構成において動作を説明すると、まず、洗濯行程において、パルセータ６が左右に回転し、洗濯兼脱水槽５内の衣類１５を撹拌しながら洗濯を行う。洗濯行程終了後、次の排水行程ではパルセータ６の回転を止め、排水弁８を開放し、水受け槽１内の洗濯液を排水する。つぎの脱水行程では排水弁８を開放した状態で洗濯兼脱水槽５を回転駆動し、衣類１５の内部に残留した洗濯液を回転による遠心力によって、水抜き用の小穴７から洗濯兼脱水槽５の外部に押し出す。
【０００６】
この脱水行程において、洗濯兼脱水槽５の遠心力で絞り出された洗濯液は、洗濯兼脱水槽５の回転とともに水受け槽１内部の下部周壁を回り続けるために、水受け槽１の底面部に設けた排水口１６から排水されにくく、残水による音や、脱水性能の低下、さらには撹拌されるために発生する泡によって洗濯兼脱水槽５の脱水回転が抑制されてしまっていた。
【０００７】
この対策として、脱水行程の初期に洗濯兼脱水槽５の回転を一時的に緩める動作を数回くり返して、高速回転時に衣類１５から絞られた洗濯液を低速回転時に水受け槽１から排水していた。
【０００８】
【発明が解決しようとする課題】
最近、この種の洗濯機における使用者からの要望として、時間短縮が強く求められるようになり、脱水行程の初期に洗濯兼脱水槽１を一時的に低速回転させることの必要性をなくすことによる脱水時間の短縮が従来からの課題であった。
【０００９】
本発明は上記課題を解決するもので、脱水行程での洗濯兼脱水槽の一時的な低速回転を必要とせずに水受け槽から洗濯液を排水できるようにし、脱水時間を短縮することを目的としている。
【００１０】
【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、洗濯兼脱水槽を内包し外枠内に弾性的に支持した水受け槽と、水受け槽の底部に設けられ水受け槽内の洗濯液の排水を制御する排水弁とを備え、水受け槽は、水受け槽の底面部に設けられ排水弁と連通する第１の排水口と、水受け槽の底面部に近接する周壁部分に設けられ排水弁へ連通する連通部と連通する第２の排水口を設けたものである。
【００１１】
これにより、排水行程では水受け槽の底面部に設けた第１の排水口より排水し、脱水行程で、洗濯兼脱水槽の回転の遠心力で絞り出された洗濯液は、水受け槽の底面部に近接する周壁部分に設けた第２の排水口より直ちに排水されるため、脱水行程での洗濯兼脱水槽の一時的な低速回転を必要とせずに水受け槽から洗濯液を排水することができ、脱水時間を短縮することができる。
【００１２】

The operation in the above configuration will be described. First, in the washing process, the pulsator 6 rotates left and right, and washing is performed while stirring the clothes 15 in the washing and dewatering tub 5. After the washing process is completed, in the next draining process, the rotation of the pulsator 6 is stopped, the drain valve 8 is opened, and the washing liquid in the water receiving tank 1 is drained. In the next dehydration step, the washing and dewatering tub 5 is driven to rotate with the drain valve 8 opened, and the washing liquid remaining inside the clothes 15 is washed from the small hole 7 for draining water by the centrifugal force caused by the rotation. Extrude to the outside of 5.
[0006]
In this dehydration process, the washing liquid squeezed out by the centrifugal force of the washing / dehydrating tub 5 continues to rotate around the lower peripheral wall inside the water receiving tub 1 as the washing / dehydrating tub 5 rotates. It was difficult to drain from the drain port 16 provided in the section, and the dewatering rotation of the washing and dewatering tub 5 was suppressed by the sound generated by the remaining water, the dewatering performance was lowered, and the foam generated by stirring.
[0007]
As a countermeasure against this, the operation of temporarily loosening the rotation of the washing and dewatering tank 5 at the beginning of the dewatering process is repeated several times, and the washing liquid squeezed from the clothing 15 at the time of high speed rotation is drained from the water receiving tank 1 at the time of low speed rotation. It was.
[0008]
[Problems to be solved by the invention]
Recently, as a request from users in this type of washing machine, time reduction has been strongly demanded, by eliminating the need to temporarily rotate the washing and dewatering tank 1 at a low speed at the beginning of the dewatering process. Shortening the dehydration time has been a conventional problem.
[0009]
The present invention solves the above-mentioned problems, and aims to allow the washing liquid to be drained from the water receiving tank without requiring a temporary low-speed rotation of the washing and dehydrating tank in the dehydration process, and to reduce the dehydration time. It is said.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the present invention includes a water receiving tub that encloses a washing and dehydrating tub and is elastically supported in the outer frame, and drains the washing liquid in the water receiving tub provided at the bottom of the water receiving tub. and a discharge valve for controlling the water receiving tank, a first discharge port and provided in the peripheral wall portion adjacent to the bottom portion of the water tub drain valve in communication with the provided on the bottom surface portion of the water tub drain valve it is provided with a second discharge port communicating with the communicating portion communicating to.
[0011]
As a result, in the draining process, the washing liquid drained from the first drain port provided in the bottom surface portion of the water receiving tank and squeezed by the centrifugal force of the rotation of the washing / dehydrating tank in the dehydrating process is stored in the water receiving tank. Since the water is immediately drained from the second drainage port provided in the peripheral wall portion adjacent to the bottom surface, the washing liquid is drained from the water receiving tank without the need for temporary low-speed rotation of the washing / dehydrating tank in the dewatering process. And the dehydration time can be shortened.
[0012]
