The control device 27 controls the display unit 29 and the buzzer 43 based on those input signals and a previously stored control program, and controls the water supply valve 20, the drain valve 10, the motor 7 and the like via the drive circuit 44. A washing operation is performed that includes washing, rinsing and dehydration processes.

  When the delicate course is selected and instructed by the user's operation on the operation panel 26, the control device 27 places the clothes W on the partition plate 50 mounted in the washing tub 5 and performs washing. Execute. This delicate course includes a washing process and a rinsing process, and the dehydration process is performed manually by the user if necessary.

  In this delicate course washing process, the water level is set slightly above the partition plate 50, and the agitator 6 is rotated in a predetermined cycle by driving the motor 7 in a normal rotation, stop, reverse rotation, and stop.

  Next, the operation when the delicate course is executed in the washing machine 1 configured as described above will be described with reference to FIGS. When the user wants to wash delicate clothes W such as a wool sweater or silk product, for example, the partition plate 50 is mounted (set) in the washing tub 5 as described above, and the clothes W to be washed are placed on the partition plate 50. Place (see FIG. 1).

  Then, after a necessary amount of detergent is introduced into the detergent introduction part, the operation panel 26 (switch input part 28) is operated to select a delicate course, and the washing operation is started. The flowchart of FIG. 8 schematically shows a procedure of processing executed by the control device 27 and the like in the delicate course.

  That is, first, the washing machine 1 is turned on (step S1), then the partition plate 50 is set (step S2), and the garment W is placed on the partition plate 50 (step S3). The power of the washing machine 1 may be turned on after the partition plate 50 and the clothing W are set. Thereafter, when the detergent is put in (step S4) and the start switch is turned on (step S5), the washing operation is started. When the washing operation is started, in step S6, the water supply valve 20 is first opened, and the washing water containing the detergent is supplied into the washing tub 5 (water tub 3). This water supply is executed until the water level in the washing tub 5 reaches a predetermined water level slightly lower than that of the partition plate 50 (step S7). When the water level reaches the predetermined water level (Yes in step S7), the water supply valve 20 is temporarily turned on. Stopped (step S8).

  In the next step S9, the stirrer 6 is intermittently driven to rotate forward and reverse. At this time, although the water level in the washing tub 5 is relatively low and does not reach the partition plate 50, the rotation of the stirring body 6 causes the water and the detergent to be vigorously stirred so that the detergent can be dissolved well, so that the detergent dissolves. It is possible to foam quickly. And by the effect | action of the pump blade | wing 36 of the stirring body 6, wash water goes up the water flow path 37 (pumping), and a shower water flow can be discharged in the washing tub 5 from the discharge outlet 37a.

  At this time, if the clothing W is relatively high in water repellency, such as a wool material, the clothing W may float on the partition plate 50 and the washing water may not easily permeate. Therefore, before the clothes W arranged and placed on the partition plate 50 are lifted, moved and folded, the shower water flows into the clothes W on the partition plate 50. Accordingly, the washing water can be infiltrated into the garment W before full-scale washing starts, and it is possible to suppress the occurrence of shape loss and uneven washing due to the garment W rising.

  When the forward / reverse rotation driving of the stirring member 6 in step S9 is executed for a predetermined time (for example, several tens of seconds), the water supply valve 20 is opened in the next step S10, and water supply is resumed. When the water level in the washing tub 5 reaches a set water level (a water level higher than that of the partition plate 50) (Yes in Step S11), the water supply valve 20 is closed (Step S12). In step S13, the stirrer 6 is driven to rotate forward and backward continuously for a predetermined time, and a washing operation is executed (step S14).

  As shown in FIG. 7, by driving the stirring body 6, the water flow generated by the convex portion 6 a of the stirring body 6 passes through the water flow holes 53 on the outer peripheral side of the partition plate 50 as indicated by the arrow A. Ascending, a rotating water flow is generated in the outer peripheral portion on the upper surface side of the partition plate 50. In addition to this rotating water flow, the washing water pumped from the pump chamber 35 through the water passage 37 is poured from the discharge port 37a toward the clothing W, and is washed like a press wash.

  By performing the delicate course washing process as described above, the garment W can be prevented from rubbing against the partition plate 50 as well as the garment W is not directly touching the stirrer 6, and the garment W can be washed with a rotating water flow. For example, a light sweater or the like can be washed while being rotated without losing its shape. Thereby, it can wash | clean gently, suppressing the damage of the clothing W. In addition, a high washing effect can be obtained for the garment W as a whole by the washing effect of the rotating water flow and the wash water (shower water flow) poured from above.

  As described above, according to the present embodiment, the partition plate 50 that has the water passage hole 53 through which the washing water passes in the outer peripheral portion and is detachably mounted in the washing tub 5 is provided and is mounted in the washing tub 5. Since the delicate course for performing washing by placing the clothes W on the partition plate 50 can be executed, the washing effect is improved while preventing the clothes W from being damaged when washing the delicate clothes W. It is possible to obtain an excellent effect of being able to.
