となる。2. Description of the Related Art As a washing machine, a spiral washing machine is generally popular. In the spiral washing machine, a washing / dehydrating tub is housed in an outer tub so as to be rotatable around a vertical axis, and a pulsator for giving a swirling force to washing water is provided at the bottom of the washing / dehydrating tub. By rotating the pulsator while the washing / dehydrating tub is stopped, the laundry spins in the water. In a swirl type washing machine, a large amount of water is required because the washing is performed by friction between the laundry items caused by turning, friction with the inner peripheral wall of the washing / dehydrating tub or friction with the pulsator.

も節水が図れる。On the other hand, a drum type washing machine is known as a washing machine which can obtain a water saving effect. In the drum type washing machine, the drum is housed in an outer tub so as to be rotatable around a horizontal axis, and a plurality of baffles extending in the horizontal direction are provided to project on an inner peripheral wall of the drum. Pour a relatively small amount of wash water into the drum and rotate the drum. The laundry in the drum is caught on the baffle and lifted, and then falls by gravity. Since the washing is performed by hitting the laundry on the water surface in the drum type washing machine, a small amount of washing water is required as compared with the swirling type washing machine, and the water can be saved more than the swirling type washing machine.

It is a big problem that it causes noise. It is an object of the present invention to provide a tap-washing mode in which a water-saving effect similar to that of a drum-type washing machine can be obtained, a frictional washing mode in which a cleaning effect equivalent to or higher than that of a spiral-type washing machine can be obtained, and a floor during dehydration operation. It is an object of the present invention to provide a washing machine capable of realizing three modes of a dehydration mode capable of suppressing the vibration propagating to a surface to the same extent as that of a spiral washing machine.

能な旋回力付与機構が設けられている。A washing machine according to the present invention is capable of rotating a washing / dehydrating tub for storing laundry in an outer tub about a vertical axis in order to suppress vibration during a dewatering operation. To house. The inner wall of the washing / dehydrating tub is provided with a screw piece capable of applying a thrust force in the vertical axis direction to the washing water as the washing / dehydrating tub rotates. Further, a turning force applying mechanism capable of giving a turning force to the washing water is provided at the bottom of the washing / dehydrating tub.

機構は、洗濯・脱水槽内の洗濯水に旋回力を与え、洗濯
・脱水槽と洗濯水の間に旋回速度の差を生じさせる。The screw piece rotates integrally with the washing / dehydrating tub, and produces a thrust on the washing water in the washing / dehydrating tub due to the difference in swirling speed between the washing / dehydrating tub and the washing water. The turning force applying mechanism applies a turning force to the washing water in the washing / dehydrating tub to cause a difference in turning speed between the washing / dewatering tub and the washing water.

能である。Specifically, in the washing machine according to the present invention, the washing / dewatering tub is rotated in a direction in which the thrust force of the screw piece is directed upward, and is swung so as to give a turning force in a direction opposite to the rotating direction. By operating the force applying mechanism to stop the rotation of the washing / dehydrating tub by tapping and washing mode of braking the swirling of the washing water accompanying the rotation of the washing / dehydrating tub, and operating the turning force applying mechanism. Friction washing mode that creates a swirling flow faster than the swirling speed in the washing water in the washing / dehydrating tub, and faster than the rotation speed in the tapping mode and friction washing mode of the washing / dehydrating tub Switching operation is possible among the three modes of the spinning dehydration mode.

返すことでドラム式洗濯機と同様のたたき洗いを施す。In the beat-wash mode, a relatively small amount of water is injected into the washing / dehydrating tub to rotate the washing / dehydrating tub in the direction in which upward thrust is generated. At least a part of the turning force applied to the washing water accompanying the rotation is canceled by the reverse turning force generated by the operation of the turning force applying mechanism, and the washing water in the washing / dehydrating tub hardly turns, or ,
It turns in the same direction at a speed lower than the rotation speed of the washing / dehydrating tub. As a result, a difference in swirling speed is generated between the washing / dewatering tub and the washing water, and the upward thrust by the screw piece acts on the washing water due to the difference in the speed. The thrust causes the laundry in the washing / dehydrating tub to be lifted to a position slightly higher than the water surface, and then falls by gravity to be struck on the water surface. By repeating the above operation, the same tapping washing as in the drum type washing machine is performed.

機と同様の摩擦洗いを施す。In the friction washing mode, a relatively large amount of water is injected into the washing / dehydrating tub, the washing / dehydrating tub is stopped or rotated, and the turning force applying mechanism is operated to wash water in the washing / dehydrating tub. A swirling flow faster than the swirling speed in the hit-and-wash mode is generated. As a result, a swirling speed difference is generated between the washing / dehydrating tub and the washing water, and due to the speed difference, an upward or downward thrust by the screw piece acts on the washing water in addition to the swirling force. For example, when an upward thrust is generated, the laundry swirls along the screw piece and ascends, and then descends at the center of the washing / dehydrating tub. Cleaning is performed by friction with the inner peripheral wall of the dehydration tank. On the other hand, when a downward thrust is generated, the laundry is swung down along the screw piece and descends, and then rises in the central portion of the washing / dehydrating tub. By repeating the above operation, the same frictional washing as in the spiral washing machine is performed.

軽微である。In the dewatering mode, centrifugal force is generated in the laundry in the washing / dehydrating tub by rotating the washing / dehydrating tub at a speed higher than the rotation speed in the tap washing mode and the friction washing mode. The centrifugal force presses the laundry against the inner peripheral wall of the washing / dehydrating tub, and drains the washing water, for example, from a large number of holes provided in the wall surface of the washing / dehydrating tub for dehydration. Here, since the rotation axis of the washing / dehydrating tub is vertical, the vibration propagating to the floor surface is as small as that of the spiral washing machine.
