ように回転数を設定している。The present invention is characterized in that the number of revolutions of the washing and dewatering tub 2 changes in the second step, which is the washing step. In the present embodiment, as shown in FIG. 4 (a), the rotation speed R2 does not spray the washing water from the washing water spray port 8a formed by the cover body 8 provided above the washing and dewatering tub 2. The rotation speed is set as shown in FIG.
As shown in (b), the number of revolutions is set so that the washing water is sprinkled from the sprinkling port 8a.

槽２の内面部に押さえつける力は増大する。At this time, the rotation speed of the washing and dewatering tub 2 is R2
When it rises, centrifugal force is applied to the laundry and the washing water in the washing and dewatering tub 2, and the laundry and the washing water move outward from the center. At this time, the amount of movement of the laundry and the washing water differs depending on the applied centrifugal force, but in the case of the laundry, the movement to the inner surface of the washing and spin-drying tub 2 is the largest, and the centrifugal force increases due to the increase in the rotation speed. In this case, the force of pressing the laundry against the inner surface of the washing and dewatering tub 2 increases.

After moving to the inner surface of the washing / dewatering tub 2, it further passes through a small hole provided in the inner surface of the washing / dewatering tub 2 and moves between the outer tub 1 and the washing / dewatering tub 2. That is, the washing water can move more than the laundry. This difference in the amount of movement between the laundry and the washing water has the effect of causing the washing water to pass through the laundry pressed by the centrifugal force on the inner surface of the washing and dewatering tub 2. And by this passing action,
Removes dirt from the laundry.

進行しない。However, the washing and dewatering tub 2 is rotated at a rotational speed R.
Even if the washing water is continuously rotated at 2, the washing water is in balance with the centrifugal force at the rotation speed R2 and does not move any more, so that the passage of the washing water is temporary and the removal of dirt does not proceed. .

物を通過する。On the other hand, the rotation speed R3 is set to be higher than R2 and the centrifugal force applied to the washing water is increased, so that the movement amount of the washing water is increased, and the rotation speed of the washing and dewatering tub 2 is increased. The washing water is sprinkled from a sprinkling port 8a constituted by the provided cover body 8. The washing water sprinkled into the washing and dewatering tub 2 from the sprinkling port 8a again passes through the laundry by centrifugal force.

行させる。As described above, the rotation of the washing and dewatering tub 2 at the rotation speed R3 at which the washing water is sprinkled from the sprinkling port 8a causes the washing water to pass continuously, and this washing water is continuously performed. The continuous passing action promotes dirt removal of the laundry.

る。FIG. 5 shows the relationship between the amount of washing water circulated from the sprinkling port 8a, that is, the amount of washing water that passes, and the washing performance by removing dirt from the laundry. Curve a in FIG. 5 shows the relationship between the circulating amount of the washing water and the washing performance when the rotation speed of the washing and dewatering tub 2 is kept constant. As shown in the curve a in FIG.
The inventors have already confirmed by experiments that the washing performance is improved by increasing the circulation amount of the washing water.

よい。Referring to FIG. 5, if the washing performance D1 is to be obtained, the circulation amount of the washing water may be finally set to Q1. When trying to obtain the washing performance D1 in a short washing time,
The continuous operation may be performed while the rotation speed of the washing and dewatering tub 2 is kept at R3.

がある。However, when the washing water is circulated, bubbles are generally generated by the detergent components in the washing water. Therefore, when the circulation of the washing water is continuously performed, the generation of bubbles also occurs continuously, and the bubbles grow with time. If the foam grows too much, it may flow out from the upper part of the washing and dewatering tub 2. In such a case, a malfunction such as a failure or malfunction of the device may occur. Therefore, certain control is required for foaming. As such a method, there is a method of controlling the amount of washing water circulated per unit time.

In the second step, the rotation speed of the washing and dewatering tub 2 is changed at rotation speeds R4 and R5 at which the amount of sprinkling of the washing water is different. That is, as shown in FIG.
When the water level in the washing and dewatering tub 2 reaches S1 ', the water supply valve 9 is stopped, and during the second stroke from T1' to T2 ', the rotation speed of the washing and dewatering tub 2 is R4 And R5.

実施例１と同じである。At this time, the rotation speed R4 and the rotation speed R5 are both the rotation speed R4 shown in FIG. 7A and the rotation speed R5 shown in FIG. The number of rotations is set so that the washing water is sprinkled from the sprinkling port 8a at the upper part of. However, the relationship between the rotation speeds R4 and R5 is as follows: R4 <R5
Therefore, the rotation speed R5 is larger than the rotation speed R4.
The amount of washing water circulation per unit time is large. Other configurations are the same as those in the first embodiment.

実験確認している。The operation of the above configuration will be described. First,
As shown in FIG. 6, the rotation speed of the washing and dewatering tub 2 rises to R5 via R4, so that the rotation speed of the washing and dewatering tub 2 is increased by the water spout 8 a formed by the cover body 8 provided above the washing and dewatering tub 2.

In order to obtain 1 ', the circulation amount of the washing water of Q1' is required. In order to obtain the washing performance D1 'in a short washing time, the washing and dewatering tub 2 may be continuously operated with the rotation speed kept at R5. However, when the washing water is circulated, bubbles are generally generated by the detergent component in the washing water.

In other words, the repeated washing operation of "push" and "release" is applied to the laundry, and the washing performance D2 'is obtained. The inventors have experimentally confirmed that the washing performance is improved as shown by the curve b in FIG.

Absent. On the other hand, as in the first embodiment, when controlling the amount of water spraying with the number of rotations at which the washing water is sprinkled and the number of rotations at which the washing water is not sprinkled, as shown in FIG. Then, there is a large difference in the number of rotations between the washing water and R5 where the washing water is sufficiently sprinkled.

From this, it can be said that controlling the amount of washing water to be sprinkled at different rotation speeds is also effective for shortening the washing time.
