っている。This type of washing machine has a simplified structure and a common motor by driving a pump for circulating liquid together with a rotary blade.

即ち、洗濯槽の内面に翼室を凹設すると共に、この翼室
内にリング状枠体を配設して翼室裏側にポンプ室を形成
腰この翼室及びポンプ室に回転翼とその裏羽根を配設す
るのである。That is, a blade chamber is recessed in the inner surface of the washing tub, and a ring-shaped frame is arranged inside this blade chamber to form a pump chamber on the back side of the blade chamber.The rotor blade and its back blade are placed in the blade chamber and pump chamber. .

従って、回転翼及び裏羽根を共通のモータによって回転
さてた時に、回転翼による通常の洗濯動作と裏羽根によ
るポンプ作用によって液の循環動作とを行なうことがで
きる。Therefore, when the rotary blade and the back blade are rotated by a common motor, the normal washing operation by the rotary blade and the liquid circulation operation by the pumping action by the back blade can be performed.

ここで、翼室及びポンプ室内に於ける液の動きを観察す
ると、ポンプ室内で圧送されようとする液はその圧送力
によってリング状枠体で区画されたポンプ室から洩れ出
ようとする。Here, when observing the movement of liquid in the blade chamber and the pump chamber, the liquid that is being pumped in the pump chamber tends to leak out of the pump chamber partitioned by the ring-shaped frame due to the pumping force.

従って、リング状枠体を翼室内に配設−固定する場合に
はシールを確実にしなければならず、もしシールが不完
全ならば液はポンプ室から枠体外に洩れ出て、枠体と翼
室周壁間から洗濯槽に直接噴出され、ポンプ能力を低下
させることになる。Therefore, when installing and fixing the ring-shaped frame in the wing chamber, a reliable seal must be ensured. If the seal is incomplete, the liquid will leak from the pump chamber to the outside of the frame, and the frame and blade It is sprayed directly into the washing tub from between the walls around the chamber, reducing the pumping capacity.

かくして、洗濯やすすぎに際しては、モータを駆動して
回転翼２５及び裏羽根２６を回転させ、まず洗濯物Ａと
液を回転させて洗濯或いはすすぎを行なう。Thus, when washing or rinsing, the motor is driven to rotate the rotary blades 25 and back blades 26, and the laundry A and liquid are first rotated to perform washing or rinsing.

又同時に液はカバー２７の通水孔２８・・・−溢排水室
８一連通路１９−人口１８−ポンプ室１１−吐出口２１
−送水枠２０及び凹溝９−吐出管２９−その上端開口３
０−リントフィルター３１−洗濯槽２と云う経路で循環
される。At the same time, the liquid flows through the water passage hole 28 of the cover 27 - overflow chamber 8 series passage 19 - population 18 - pump chamber 11 - discharge port 21
- Water frame 20 and groove 9 - Discharge pipe 29 - Its upper end opening 3
It is circulated through the path 0-lint filter 31-washing tub 2.

従って、洗濯時の洗浄効果は向上し、又糸クズ等はリフ
トフィルター３１によって捕獲される。Therefore, the cleaning effect during washing is improved, and lint and the like are captured by the lift filter 31.

そして、透孔２２は液をバイパスして第３図矢印の如く
洗濯槽２内の液回転中心に集中的に噴き上げ、空気や洗
濯物Ａの吸込みを防止している。The through holes 22 bypass the liquid and spray it concentratedly at the center of rotation in the washing tub 2 as indicated by the arrow in FIG. 3, thereby preventing air and laundry A from being sucked in.

又、ポンプ室１１に於いて、液は裏羽根２６による圧送
力によって内周壁１５に沿って吐出口２１に導ひかれる
が、一部は圧送力によって溝１６と内周壁１５や張出片
１４との小さな隙間から枠体１０外に洩れる。Further, in the pump chamber 11, the liquid is guided to the discharge port 21 along the inner circumferential wall 15 by the force of the back blade 26, but a part of the liquid is drawn into the groove 16, the inner circumferential wall 15, and the overhang piece 14 due to the force of the force. It leaks out of the frame 10 from a small gap between the two.

しかし、内周壁１５と翼室７周壁間にて抵抗壁２４によ
って邪魔されてそれ以上は洩れにくい。However, it is blocked by the resistance wall 24 between the inner circumferential wall 15 and the circumferential wall of the blade chamber 7, and leakage is difficult to occur beyond that point.

このように本考案による洗濯機は、ポンプ室を翼室内に
区画形成する枠体に、枠体と翼室周壁間に位置する抵抗
壁を、設けたので、液がポンプ室から圧送力によって枠
体外に洩れても抵抗壁によってそれ以上の洩れを抑制す
ることができ、ポンプ能力の低下を押えることができる
。As described above, in the washing machine according to the present invention, the resistance wall located between the frame and the circumferential wall of the blade chamber is provided on the frame that partitions the pump chamber into the blade chamber, so that the liquid is transferred from the pump chamber to the frame by the pressure force. Even if it leaks out of the body, further leakage can be suppressed by the resistance wall, and a decrease in pump performance can be suppressed.

又、枠体外で洩れを抑制できるので、枠体と翼室底面と
のシール構造をルーズにでき、例えば枠体の設計精度を
粗くでき、作りやすくできる等の利点がある。In addition, since leakage can be suppressed outside the frame, the sealing structure between the frame and the bottom of the wing chamber can be made loose, and there are advantages such as, for example, the design accuracy of the frame can be roughened, making it easier to manufacture.
