発生する。The conventional dehydration imbalance detection switch and lid switch of a full-automatic washing machine have some structural differences, but basically, as shown in FIG. 1 and FIG. When the lid is opened, the lid switch is cut off to stop the dehydration so that the rotating part is not touched by the hand, especially during dehydration. Also, when spinning in the spinning tub, the clothes in the washing tub are biased in one direction, and when the washing tub hits the outer frame and the entire washing machine vibrates abnormally and it becomes impossible to dehydrate, the lid switch is turned off to stop the dehydration. . However, if you wash clothes with various kinds of clothes, such as synthetic clothing that does not contain water easily, or if you wash rain gear, it will float on the top of the washing tub, and if you spin off the clothes as it is, the clothes will pop out of the washing tub and the top of the washing tub and the laundry will be washed. Problems such as being caught between the frames of the machine and tearing clothes or damaging the washing machine occur.
本発明の目的は脱水時に飛出した衣類をアンバランス検
知スイッチ兼蓋スイッチを利用して検出することにあ
る。An object of the present invention is to detect clothes that have jumped out during dehydration by using an unbalance detection switch / cover switch.
本発明は、全自動洗濯機の蓋の開閉に応じた変位するア

スイッチにおいて、アンバランス検知レバーは、洗濯槽
の半径方向と接線方向の両方向に変位可能に支持されて
おり、前記いずれの方向に変位した場合にも前記接点を
作動させることを特徴とするものである。The present invention is provided with a contact that is operated by an arm that is displaced according to opening and closing of the lid of a fully automatic washing machine and an unbalance detection lever that is disposed so as to face the outer periphery of the washing tub and that is displaced by abnormal vibration during dehydration. In the unbalance detection switch and the lid switch, the unbalance detection lever is supported so as to be displaceable in both the radial direction and the tangential direction of the washing tub, and the contact is activated in any of the above directions. It is characterized by.
脱水時に洗濯物に偏りが生じて異常振動が発生した場合
には、アンバランス検知レバーが槽の半径方向に押され
て接点を開き、洗濯槽から洗濯物が飛び出してその洗濯
物がアンバランス検知レバーに当たると、同検知レバー
は洗濯物の接線方向に動いて接点を開くことになる。If uneven laundry occurs during spin-drying and abnormal vibration occurs, the unbalance detection lever is pushed in the radial direction of the tub to open the contact point, the laundry pops out of the tub, and the unbalance is detected. When hitting the lever, the detection lever moves in the tangential direction of the laundry to open the contact.
このため脱水時には、異常振動と洗濯物の飛び出しの両
方の異常状態を検知して脱水を停止するものである。Therefore, at the time of dehydration, the abnormal conditions of both the abnormal vibration and the popping out of the laundry are detected to stop the dehydration.

指４を有し、下部には洗濯槽の外周と所定の間隔を介し
て位置するレバー部3aを有する。3 is an imbalance detection lever, which is formed in a crank shape,
The movable arm 2 is inserted into the punched-out portion 2b, and the notch portion 3b is fitted with the rising portion of 2a, and is rotatably held with this as a fulcrum. The imbalance detection lever 3 has a contact finger 4 on the upper portion thereof, and has a lever portion 3a on the lower portion thereof which is located at a predetermined distance from the outer periphery of the washing tub.
前記接触指４の上面は傾斜部4aを有し、この傾斜部4aは

固定ベース１とアンバランス検知レバー３の間で挟持さ
れ、常時アンバランス検知レバー３を立上り部2aを支点
に反時計方向に付勢している。The upper surface of the contact finger 4 has an inclined portion 4a, and the inclined portion 4a is a rib 4b. The rib 4b is a protrusion 11 on the lower surface of the dowel 11.
It is slidably held in the recess 11b of a. A pressing spring 5 is sandwiched between the fixed base 1 and the unbalance detecting lever 3, and constantly urges the unbalance detecting lever 3 counterclockwise with the rising portion 2a as a fulcrum.
12は洗濯投入口の蓋で、前記可動アーム２を操作する12
aの受台を有し、13の軸を中心に回動自在に固定されて
いる。Reference numeral 12 is a lid for the laundry insertion port, which operates the movable arm 12
It has a pedestal a and is fixed so as to be rotatable around 13 axes.
次に動作を説明すると、蓋12を開けると受台12aは可動
アーム２を離れ、可動アーム２は押ばね５により下降す

点９と10は開状態となる。Next, the operation will be described. When the lid 12 is opened, the pedestal 12a leaves the movable arm 2 and the movable arm 2 is lowered by the pressing spring 5. When the movable arm 2 is lowered, the contact finger 4 and the imbalance detection lever 3 are also lowered, and the dowel 11
Is displaced downward, the contact piece 8 on the dowel 11 is lowered, and the contacts 9 and 10 are opened.
また、アンバランス検知レバー３のレバー部3aが洗濯槽

傾斜面に沿って落下し、これの上面に乗っている接片８
も落下するため、接点9,10は開状態となる。When the lever portion 3a of the imbalance detection lever 3 is pushed clockwise due to abnormal vibration of the washing tub, the contact finger 4 rotates about the rising portion 2a as a fulcrum. When rotated, the dowel 11 falls along the inclined surface of the contact finger 4, and the contact piece 8 mounted on the upper surface of the dowel 11 falls.
Also falls, so that the contacts 9 and 10 are opened.
上記２通りの開状態は、前者は蓋を閉めることで、又後
者はレバー部3aの押力を除去することで解除される。The two open states are released by closing the lid for the former and removing the pressing force of the lever portion 3a for the latter.
次に衣類の洗濯槽から飛出しによる動作を説明すると、

接点9,10を開状態にする。この開状態は前記の蓋12を開
けることで、固定アーム２で、アンバランス検知レバー
３が下降し解除される。アンバランス検知レバー３の傾
きは押ばね５の付勢力で回復される。Next, explaining the operation by jumping out of the clothes washing tub,
When the popped-out clothes rotate together with the tank, the lever portion 3a is hit in the tangential direction of the tank and tilts with the rising portion of 2a as a fulcrum. At this time, the rib 4a of the contact finger 4 is disengaged from the protrusion 11a of the dowel 11. The projection 11a of the dowel 11 instantly drops together with the contact piece 8 to open the contacts 9 and 10. In this open state, when the lid 12 is opened, the imbalance detection lever 3 is lowered and released by the fixed arm 2. The inclination of the unbalance detection lever 3 is restored by the biasing force of the pressing spring 5.
本発明によれば蓋の開閉及び脱水時の異常振動により接
点を作動させることはもちろん、脱水時に槽から飛出し

又は、洗濯機の破損等は未然に防止することができるも
のである。According to the present invention, the contacts can be operated by abnormal vibration during opening / closing of the lid and dehydration, and the clothes that have jumped out of the tank during dehydration can be operated by the force of hitting the unbalance detection lever. It is possible to prevent breakage of clothes or breakage of a washing machine due to jumping out.
