When the liquid detergent 17 is selected, the liquid detergent, particularly the neutral liquid detergent, can be rinsed more easily than when washed with the powder detergent. In comparison, the contents of the rinsing process can be simplified.
[0034]
As described in the first embodiment, when it is selected that the liquid detergent 17 is not charged by the detergent charging setting switch 24f, the sequence shown in FIG. 4 is performed, and the liquid detergent 17 is switched by the detergent charging setting switch 24f. If it is selected to input 17, the sequence shown in FIG. 6 is rinsed.
[0035]
As shown in FIG. 6, after the washing process, the water is drained for intermediate dehydration, and water injection is rinsed (2 minutes). As described above, when the liquid detergent 17 is selected to be introduced, the same rinsing performance can be obtained even if the waterfall rinsing is omitted.
[0036]
In the present embodiment, after the washing process, in the rinsing process, draining and intermediate dehydration are performed, and water injection rinsing (2 minutes) is performed. However, this combination is an example, and other combinations may be used.
[0037]
(Example 3)
The control means 21 shown in FIG. 1 sets the water level in the washing / dehydrating tub 1 to be low when the detergent loading setting switch 24f selects the loading of the liquid detergent 17. Other configurations are the same as those of the first embodiment.
[0038]
The operation in the above configuration will be described. Before starting the operation, it is selected whether or not the liquid detergent 17 is charged by the detergent charging setting switch 24f. When the liquid detergent 17 is selected to be introduced, when the set water level is a high water level and a medium water level, the water level in the washing and dewatering tub 1 is set as compared with the case where the liquid detergent is not charged, that is, compared with the powder detergent. Set the water column 30 mm lower.
[0039]
Therefore, it is better to store more water in the washing and dewatering tub 1 and stir with the stirring blade 2 to improve the laundry around the laundry. It is easy to discharge ingredients. That is, the rinsing performance is improved.
[0040]
On the other hand, if the liquid detergent 17 is selected, the liquid detergent, particularly a neutral liquid detergent, can be rinsed more easily than when washed with a powder detergent. Compared to when no charging is performed, rinsing can be performed efficiently with a small amount of water, thus saving water and saving energy.
