ある。As shown in FIG. 15, the outer tub 30 includes a washing and dewatering tub 32 in which a stirring blade 31 is rotatably disposed at the bottom, and is suspended from a washing machine outer frame 34 by a suspending rod 33. . The motor 35 is connected to the stirring blade 31 or the washing / dewatering tub 32 via a V-belt 36 and a speed reduction mechanism / clutch 37.
Drive. The drain valve 38 drains the washing water in the washing and dewatering tub 32, and the water supply valve 39 supplies water to the washing and dewatering tub 32. The washing and dewatering tub 32 is provided with a fluid balancer 40 for reducing vibration during dehydration, and a lid 41 is provided above the washing and dewatering tub 32. Control device 42
Controls the motor 35, the drain valve 38, the water supply valve 39, and the like to sequentially control the washing, rinsing, and dehydrating processes.

用することとなる。The operation of the above configuration will be described. After the laundry and a predetermined amount of detergent are put into the washing / dewatering tub 32, when the washing is started, the water supply valve 39 is controlled by the control device 42 so that the inside of the washing / dewatering tub 32 is opened. Is supplied with a predetermined amount of water, and then the control device 42 controls the motor 35 to rotate the stirring blade 31. The laundry and the water in the washing / dewatering tub 32 are stirred by the rotation of the stirring blade 31, and the detergent gradually dissolves into washing water by this stirring, thereby acting on the soil of the laundry.

【発明が解決しようとする課題】しかしながら、この構

攪拌翼３１を高速で回転させて洗濯物や水を撹拌するの
が一般的であり、この場合、洗濯物に過度の機械力が加
わらないようにするため、洗濯兼脱水槽３２に所定量の
水を給水してから攪拌翼３１による撹拌を行っていた。However, in the case of the washing machine of this configuration, in order to dissolve the supplied detergent,
It is common to rotate the stirring blade 31 at high speed to stir the laundry and water. In this case, in order to prevent excessive mechanical force from being applied to the laundry, a predetermined amount of After water was supplied, stirring by the stirring blade 31 was performed.

洗剤が、洗濯物全体に浸透し、汚れ除去に必要な濃度に
均一化されるまで所定の時間が必要となり、この場合も
汚れ除去の観点からすると無駄な時間となっていた。In other words, since the stirring blade 31 is not stirred until a predetermined amount of water is supplied, this water supply time has no meaning from the viewpoint of removing stains from the laundry. In addition, the supplied water will permeate the laundry as it is, and in this case, the detergent that has begun to dissolve due to the start of stirring penetrates the entire laundry and reaches a predetermined level until the concentration is uniform to a level necessary for removing stains. Time is required, and in this case too, it is wasted time from the viewpoint of dirt removal.

の結果として洗濯物表面に毛羽立ちなどの傷みが生じて
まうという問題点があった。In addition, starting stirring by the stirring blade 31 from a state where the detergent does not sufficiently act on the laundry is inefficient from the viewpoint of damage to the laundry. That is,
If the laundry is agitated in a state where the detergent is not soaked in the laundry, a large frictional force is applied to the surface of the laundry, and as a result, there is a problem that the surface of the laundry is damaged such as fluff.

損傷や絡みを低減することを目的としている。The present invention solves the above-mentioned problems, and dissolves the detergent simultaneously with the start of water supply without rotating the stirring blade, and evenly dissolves the washed washing water without rotating the stirring blade. The purpose of this method is to reduce the damage and entanglement of the laundry by reducing the frictional force applied to the laundry while reducing the frictional force applied to the laundry while reducing the frictional force applied to the laundry while reducing the frictional force applied to the laundry while spraying water to ensure effective use of the washing time, as well as to secure the washing power and reduce the washing unevenness I have.

After the laundry and the detergent are put into the washing and dewatering tub 2, the water supply valve 10 is operated to supply water into the washing and dewatering tub 2 while washing. The first step of rotating the double spin tub 2 is performed. As shown in FIG. 3A, until the water level in the washing and dewatering tub 2 reaches the set water level S1, the washing and dewatering tub 2
Rotates at a rotation speed R1 as shown in FIG. When water is supplied while rotating the washing and dewatering tub 2 in this manner, the supplied detergent starts to dissolve due to the stirring force generated by the rotation of the washing and dewatering tub 2, and as shown in FIG. The washing water concentration in the washing and dewatering tub 2 increases at the same time as the rotation starts. Then, it temporarily goes through a high concentration state exceeding 100% and finally reaches a concentration of almost 100%.

めることはない。The operation of the first step is to supply water to the set water level while rotating the washing and dewatering tub 2. During this first step T1, the washing water having a high concentration gradually penetrates into the laundry and acts on the laundry, and the washing water passes through the laundry by centrifugal force generated by the rotation of the washing and dewatering tub 2,
Acts on laundry stains. Also, in this first step,
Since the frictional force is not directly applied to the laundry, the laundry is not damaged.

At the time T1 when the water level in the washing and dewatering tub 2 reaches S1, the water supply valve 10 is stopped, and the rotation speed of the washing and dewatering tub 2 is reduced. Rise. As the rotation speed of the washing and dewatering tub 2 increases, the power of stirring the washing water in the washing and dewatering tub 2 increases, and the water surface in the washing and dewatering tub 2 lowers in the center as shown in FIG. Then, the space between the washing and dewatering tub 2 and the outer tub 1 rises, and finally water is sprayed into the washing and dewatering tub 2 beyond the height of the upper end of the washing and dewatering tub 2. The rotation speed R2 is set in advance to a rotation speed at which the washing water is sprinkled into the washing and dewatering tub 2.

傷めることない。The operation of the second operation is a process in which the washing water is sprinkled from the upper portion of the washing and dewatering tub 2 during the period from T1 to T2 and circulates through the laundry. By this process, the washing water can be evenly supplied to the laundry, and the sprinkled washing water repeatedly circulates through the laundry by centrifugal force generated by the rotation of the washing and dewatering tub 2,
The dirt adhering to the laundry is removed by the repeated passage of the washing water. Also, in the second step, the laundry is not directly agitated at the time of spraying and passing the washing water, so that the laundry is not damaged.

The washing and dewatering tub 2 is rotated to sprinkle and circulate the washing water on the laundry for a predetermined time. To stop. Thereafter, as shown in FIG. 5, the stirring blade 8 is operated to stir the laundry. As shown in FIG. 3, during the period from T2 to T3, the step of stirring the laundry with the stirring blades 8 to remove dirt is the operation of the third step.

る低浴比状態は汚れ除去には好ましい状態である。The reason why the rotation speed of the stirring blade 8 is changed in accordance with the water level in this manner is to prevent an excessive stirring force from being applied to the laundry so as to prevent the laundry from being damaged. For example, in order to increase the concentration of the washing water in the
When the water level at the start of the step is set to S8 lower than a predetermined value, from the viewpoint of washing, a high concentration state with little water, that is, a so-called low bath ratio state is a preferable state for dirt removal.

わることがなくなるからである。However, from the viewpoint of damage to the laundry, rotating the stirring blade 8 at a high bath rate in a low bath ratio may cause an excessive load on the laundry to cause damage. For this reason, in the state of a low bath ratio, it is preferable to set the rotation speed of the stirring blade 8 low. Water is supplied into the washing and dewatering tub 2 from ta2 to ta3, and as the relationship between the laundry and the washing water progresses from a low bath ratio to a high bath ratio, the stirring blades 8
Is gradually increased to P1, P2 and P3. That is, as the bath ratio increases, the movement of the laundry by the operation of the stirring blades 8 can be performed smoothly, so that an excessive load is not applied to the laundry.
