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.

ある。A drain valve 38 drains the washing water in the washing and dewatering tub 32, and a 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 construction will be described. After the laundry and a predetermined amount of detergent have been put into the washing and dewatering tub 32, when the operation is started, the water supply valve 39 is controlled by the control device 42, and 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.
【０００６】[0006]
【発明が解決しようとする課題】しかしながら、このよ
うな従来の構成では、投入された洗剤を溶解するため
に、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 such a conventional configuration, it is common to rotate the stirring blade 31 at a high speed to stir the laundry and water in order to dissolve the detergent added. In this case, in order to prevent excessive mechanical force from being applied to the laundry, a predetermined amount of water is supplied to the washing / dewatering tub 32 and then the stirring by the stirring blades 31 is performed.
【０００７】つまり、所定量の水が給水されるまでは攪
拌翼３１を撹拌させないため、この給水時間は洗濯物の
汚れ除去の観点からは、意味を持たないものとなってい
た。また、給水された水は洗濯物にそのまましみ込むこ
とになり、この場合、撹拌開始によって溶解しはじめた
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。That is, since the stirring blades 31 are not stirred until a predetermined amount of water is supplied, the 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.

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。Further, it is inefficient to perform stirring by the stirring blades 31 while the detergent is not sufficiently acting on the laundry from the viewpoint of damage to the laundry. That is,
When the laundry is stirred in a state where the detergent has low solubility, mechanical force by the stirring blades 31 while the washing effect of the detergent is low, that is, frictional force is applied to the laundry surface, and as a result, the laundry surface becomes fuzzy. However, there is a problem that the damage is caused.

It is intended to act on dirt.

The control means controls the operation of a water supply means for supplying water to the water, a driving means for driving the washing and dewatering tub or the stirring blades to control the stroke, and the control means rotates the stirring blades at a predetermined water level. A second step of sprinkling washing water from between the outer tub and the washing / dewatering tub into the washing / dewatering tub by rotation of the washing / dewatering tub is performed before the step or at least one of between the first steps. It is like that.

る。Further, mechanical power is added to the laundry by stirring, but the friction mechanical force applied to the surface of the laundry is reduced by the lubricating action of the washing water permeated into the laundry, and the detergent is removed by the first stroke. Since the material is dissolved, the stirring time can be reduced by that amount, and damage to the laundry caused by applying excessive friction mechanical force can be prevented.

いむらを低減することができる。In the second step between the first steps, the washing water in which the detergent has been dissolved is washed by the centrifugal force generated by the rotation of the washing and dewatering tub 2 so that the washing water passes through the laundry. Acts on dirt. Further, in the second step, since no frictional force is directly applied to the laundry, the laundry is not damaged, the cleaning power can be secured, and the washing unevenness can be reduced.

The load amount detecting means 22 is for detecting the amount of the laundry in the washing and dewatering tub 2. The output of the rotation detecting means 21 is inputted, and the motor 5 is loaded in the washing and dewatering tub 2. Then, the amount of the laundry in the washing and dewatering tub 2 is detected based on the degree of decrease in the rotation speed of the stirring blade 8 when the driving is stopped after the stirring blade 8 is driven.

濯兼脱水槽２内の洗濯物の量を検知する。The operation of the above configuration will be described with reference to FIG. When the operation is started after the laundry and the detergent are put into the washing / dewatering tub 2, the motor 5 is operated by the control means 23 to agitate the agitating blades 8, and the laundry is agitated for a predetermined time T4. At this time, a signal generated by the rotation detecting unit 21 is sent to the load amount detecting unit 22, and the amount of the laundry in the washing and dewatering tub 2 is detected based on the signal.

The rotation speed set so that a predetermined amount of washing water is sprinkled is R2
If the amount of laundry is small in the same water level, the amount of washing water sprinkled into the washing and dewatering tub 2 is easy because the washing water in the washing and dewatering tub 2 easily passes through the laundry. , The washing water becomes excessively foamed, and the rotation speed R

Can be suppressed, and the optimal dissolution of the detergent and the optimal spraying of the washing water can be performed. Therefore, the scattering of the washing water can be prevented, the power consumption can be reduced, and the temperature of the motor 5 can be prevented from rising.

For this reason, when the amount of the laundry is large, as shown in FIG. 8, the operation times t1 and t2 of the first and second strokes are the first time when the amount of the laundry shown in FIG. And the operation times t1 'and t2' of the second stroke are set longer (t1> t1 ', t2>t2').
