で効率良く行えた。2. Description of the Related Art Conventionally, in a fully automatic washing machine, washing, rinsing and dewatering steps are carried out in a washing and dewatering tank, and the dewatering step is carried out before, after and during the rinsing step. Various methods have been proposed to enhance the effect of this rinsing. For example, as disclosed in Japanese Patent Laid-Open No. 3-70590, at the time of water supply for the rinsing process, by rotating the pulsator from the middle of the water supply,
The laundry stuck to the inner wall of the washing / dehydrating tub in the dehydrating step of the previous step is peeled off from the inner wall of the washing / dehydrating tub by the water flow and is loosened. Then, usually, the rinsing process was started after supplying water up to the same water level as the washing process. Since the laundry has already been loosened at the start of the rinsing process, the subsequent rinsing effect is high. In addition to the high rinsing effect, the rinsing effect can be obtained from the middle of the water supply by rotating the pulsator from the middle of the water supply, so that the rinsing can be performed efficiently in a short time.

は、充分に洗濯水に浸かることができる。Next, the water supply to the washing / dehydrating tank 5 is started again, and the water supply is continued until the set water level in step S2 is detected by the water level sensor 9 (step S8). As shown in FIG. 5 (c), the laundry at this time is collected in the center of the bottom of the washing / dehydrating tub in step S7 and further absorbs water, compared to the state before washing shown in FIG. 5 (a). Since the volume is small, the laundry can be sufficiently immersed in the wash water at the above set water level.

を終了する。After the water supply is completed, the pulsator 7 is rotated for a predetermined time to perform a rinsing process (step S9). After completion of the rinsing process, the drain valve 18 is opened to drain the water from the washing / dehydrating tank 5 (step S10). After the drainage, the washing / dewatering tank 5 and the pulsator 7 are rotated at a high speed for a predetermined time to perform a dehydration process (step S11). In step S12, if the above-described rinsing process has been performed a predetermined number of times, for example, twice, the entire process is ended.

時間を短縮することができる。As described above, when the pulsator 7 is operated for a predetermined time in step S7, the water supply operation is stopped,
Also, since the water level is low, there is no risk of water splashing regardless of the state of the laundry. Further, by setting the rinsing water level low, there is less risk of water splashing during the rinsing process.
In addition, by setting the rinsing water level lower than the rinsing water level to such an extent that the laundry having a small volume is immersed before the rinsing step, it is possible to reduce the amount of water used together with a sufficient rinsing effect. Further, since the laundry is unraveled to some extent before the rinsing step, the rinsing effect is high, so that the rinsing time can be shortened.

る。Further, in step S2, the wash water level is determined by the additional water supply controlled by the timer in addition to the set water level corresponding to the rinse water level, so the water levels are set separately according to the rinse water level and the wash water level. No need, easy operation. Further, even if the rise time of the water level may differ due to fluctuations in the tap water pressure, its effect on the wash water level can be reduced, so that the wash water level can be obtained accurately.

ある。In the embodiment of the present invention, the washing water level is
After the set water level is detected by the water level sensor 9, it is obtained by supplying additional water for a predetermined time, but the present invention is not limited to this.
For example, the detection time of the water level sensor 9 may be set as the wash water level, and the rinse water level may be supplied by multiplying the water supply time up to the wash water level by a predetermined ratio. In addition, various design changes can be made without changing the gist of the present invention.

で、水飛びの虞はより少ない。According to the invention of claim 1, this fully automatic washing machine does not supply water when the pulsator is in the middle of the water supply process for performing the rinsing process, regardless of the state of the laundry. Since there is no risk of water splashing, it can be used with confidence. According to the invention of claim 2, claim 1
In addition to the effect described in (1), even if the rinse water level is set lower than the wash water level, the laundry can be sufficiently immersed in the rinse water, so that the rinse effect is sufficiently achieved and the amount of water used can be reduced. In addition, since the rinse water level is set low, there is less risk of water splashing.

It is not necessary to set the water level separately depending on the rinse water level and the wash water level, which simplifies the operation. According to the invention of claim 4, in addition to the effect of claim 1, there is no risk of water splashing, and a water level suitable for peeling off the laundry stuck to the inner wall of the washing / dehydrating tub can be obtained.
