Description

本発明は洗濯機の分野に関し、特に節水洗濯機の排水構造および洗濯機である。   The present invention relates to the field of washing machines, and more particularly, to a drainage structure of a water-saving washing machine and a washing machine.

周知のように、パルセータ洗濯機は、洗濯時間が短い、洗浄度が高い、途中で衣類を追加するのが便利であるなどの利点を有する。しかし、その水使用量は相対して比較的多く、一般的な８Ｋｇのパルセータ洗濯機は、標準的なプログラムで洗浄を１回、すすぎを２回行うと、水の消費量が約１８０Ｌ前後であり、水の消費量が多い。さらに内外槽間は洗浄しにくく、容易に細菌が繁殖する。   As is well known, the pulsator washing machine has advantages such as a short washing time, a high degree of washing, and convenient addition of clothing on the way. However, the amount of water used is relatively large, and a typical 8 kg pulsator washing machine consumes about 180 liters of water when it is washed once and rinsed twice with a standard program. There is a lot of water consumption. Furthermore, it is difficult to clean between the inner and outer tanks, and bacteria can easily propagate.

上記問題を解決するため、内槽に孔を有さない構造が開発された。洗濯時、内槽および外槽の間に水は無いが、内槽内の水の排出が問題となっている。そこで、内槽の上部に排水孔を１周に設置し、内槽中のすべての水を内槽の回転による遠心力で、上部の排水孔から排出するものがある。このような設計は、一方では排水が比較的遅く、もう一方では水中の泥、砂などの汚れを排出するのが難しい。さらに、内槽のちょうど下方に水受け空洞を設置する設計がある。水受け空洞は内槽と通じ、水受け空洞の上縁および内槽の下縁は密封される。水受け空洞の下部に排水孔を設置し、排水孔の開閉を制御することにより、排水の制御を実現する。しかし、脱水時、内槽は高速回転するが、水受け空洞は固定されて回転しないため、両者の間の密封は容易に実現しない。たとえ容易に実現しても、長期的な高速回転により摩耗も生じやすくなる。さらに、内槽底部に排水孔を設置する設計がある。洗濯時、内槽を定位した後、排水弁で内槽底部の排水孔を閉じ、排水時、排水弁は排水孔を開くように制御される。このような構造は内槽の定位構造を設置する必要もあり、定位の精度に対する要求は高く、構造は複雑である。さらに、洗濯時、内槽は回転することができず、ダブルドライブ洗濯を実現することができない。   In order to solve the above problems, a structure having no holes in the inner tank has been developed. At the time of washing, there is no water between the inner tub and the outer tub, but the discharge of water in the inner tub is a problem. Therefore, there is a type in which a drainage hole is installed in the upper part of the inner tank and all the water in the inner tank is discharged from the upper drainage hole by centrifugal force due to the rotation of the inner tank. Such a design, on the one hand, is relatively slow in draining, and on the other hand it is difficult to drain dirt such as mud and sand in the water. Furthermore, there is a design in which a water receiving cavity is installed just below the inner tank. The water receiving cavity communicates with the inner tank, and the upper edge of the water receiving cavity and the lower edge of the inner tank are sealed. Drainage control is realized by installing a drainage hole in the lower part of the water receiving cavity and controlling the opening and closing of the drainage hole. However, at the time of dehydration, the inner tank rotates at a high speed, but the water receiving cavity is fixed and does not rotate, so that sealing between the two is not easily realized. Even if easily realized, wear is likely to occur due to long-term high-speed rotation. In addition, there is a design to install a drain hole at the bottom of the inner tank. After washing the inner tub during washing, the drain valve closes the drain hole at the bottom of the inner tub with the drain valve, and when draining, the drain valve is controlled to open the drain hole. In such a structure, it is necessary to install a stereotaxic structure of the inner tank, and there is a high demand for the accuracy of localization, and the structure is complicated. Furthermore, the inner tub cannot rotate during washing, and double drive washing cannot be realized.

このことを考慮して、本発明を示す。   In view of this, the present invention will be described.

図１、図２に示すように、本発明の前記節水洗濯機の排水構造は、洗濯機の内槽底部に中心孔１が設けられ、前記中心孔１の周囲に環状溝２が設けられる。環状溝２に内槽内部および内槽外部を連通する水流通路が設けられ、前記環状溝２内に、往復運動して水流通路の導通、遮断を制御することができる密封部材３が設けられる。洗濯時、前記密封部材３はある位置まで運動して、水流通路を遮断し、洗濯水は内槽中にのみ存在する。排水時、前記密封部材３が別の位置まで運動して、水流通路が開き、洗濯水は水流通路、外槽を通過して排出される。密封部材３の往復運動を制御すれば、排水の制御を実現することができ、制御は簡単である。前記密封部材３は内槽底７の環状溝２内に設置され、内槽と回転方向に相対して固定され、密封部材の摩耗は小さく、信頼性が高い。   As shown in FIGS. 1 and 2, in the drainage structure of the water-saving washing machine of the present invention, a center hole 1 is provided at the bottom of the inner tub of the washing machine, and an annular groove 2 is provided around the center hole 1.

Then, the sealing member 3 is pushed out by the restoring force of the elastic member 4 so that the flowing water passage is sealed. A driving member 5 is provided at a lower portion of the sealing member 3 so as to move the sealing member upward so as to be detached from the bottom of the inner tank and / or the annular groove. Under the traction drive, the sealing member 3 is driven upward. The upward driving force is larger than the restoring force of the elastic member 4, and the sealing member 3 is moved upward to disengage from the inner tank bottom 7 and / or the bottom surface of the annular groove, open the flowing water passage, and the water in the inner tank Is discharged. In the natural state, the restoring force of the elastic member 4 pushes out the sealing member 3 to seal the flowing water passage, and at the time of drainage, the driving member moves the sealing member upward so as to move from the inner tank bottom and / or the annular groove. Control to detach, open running water passage and realize drainage.

密封部材３外周における上部の直径は下部の直径より大きく、密封部材外周の直径が突然変化する部分が第１段差６を形成する。閉鎖状態は、前記第１段差６が内槽底７にぴったりとくっつき、環状の端面の接触による密封を形成し、密封部材３底部の端面が前記環状溝の底面にぴったりとくっつき、環状の端面の接触による密封を形成する。開放状態は、前記第１段差６が内槽底７から離脱し、密封部材底部の端面が前記環状溝の底面から離脱する。密封状態は、前記密封部材３が前記内槽底７にぴったりとくっつき、密封部材３底部の端面および前記環状溝の底面がいずれも環状の端面で、接触して密封し、密封は信頼できる。前記密封部材は環状スリーブ構造であり、前記密封部材外周の上部に、外側に突起する１周のボスが設けられる。閉鎖状態は、前記ボスの下表面が内槽底にぴったりとくっつき、密封を形成し、密封部材の下部は内槽底の環状溝内に嵌入される。閉鎖状態は、前記密封部材の底部が前記環状溝の底面にぴったりとくっつき、環状の端面の接触による密封を形成し、さらに密封効果を保証する。   The diameter of the upper part of the outer periphery of the sealing member 3 is larger than the diameter of the lower part, and a portion where the diameter of the outer periphery of the sealing member suddenly changes forms the first step 6. In the closed state, the first step 6 is closely attached to the inner tank bottom 7 to form a seal by contact with the annular end surface, and the end surface of the bottom of the sealing member 3 is closely attached to the bottom surface of the annular groove.
