The portion 60 communicates between the upper surface and the lower surface of the separator 50 .

FIG. 6 schematically shows the electrical configuration of washing machine 1 according to this embodiment. Input to the control device 27 for controlling the washing machine 1 as a whole is from the switch input part 28, the water level sensor 13, and is provided on the motor 7 as the rotational driving source of the washing tank 5 and the agitator 6 for detecting the rotational speed of the motor 7. The signal of the rotation sensor 42, etc. The control device 27 controls the display unit 29 and the buzzer 43 based on these input signals and a pre-existing control program, and simultaneously controls the water supply valve 20, the drain valve 10, the motor 7, etc. A washing operation consisting of a spin cycle.

In addition, if the user selects and instructs the soft washing course by operating the operation panel 26, the control device 27 executes the soft washing course of placing the clothes W on the partition 50 installed in the washing tank 5 for washing. The soft washing process includes a washing process and a rinsing process, and if necessary, the user performs a dehydration process through manual operation.

In the washing process of the soft washing process, the water level is set slightly above the partition 50, driven by the motor 7, the agitator 6 repeatedly performs forward rotation, stop, reverse rotation, and stop according to a prescribed cycle.

Next, the operation when the soft washing course is executed in the washing machine 1 having the above-mentioned structure will be described with reference to FIGS. 7 and 8 . When the user wants to wash soft clothes W such as woolen sweaters or silk products, as described above, the partition 50 is installed (assembled) in the washing tank 5 (refer to FIG. Clothing W.

Then, after injecting a required amount of detergent into the detergent input portion, the soft washing course is selected by operating the operation panel 26 (switch input portion 28) to start the washing operation. The flow chart of Fig. 8 schematically shows the processing procedures executed by the control device 27 and the like in the soft washing course.

That is, first, the power of the washing machine 1 is turned on (step S1), then the partition 50 is installed (step S2), and at the same time, the clothes W are placed on the partition 50 (step 3). The power supply of the washing machine 1 can also be turned on after the partition 50 is installed and the clothes W are placed. Then, after putting in the detergent (step S4), the start switch is turned on (step S5), and the washing operation starts. When the washing operation is started, first, the water supply valve 20 is opened to supply washing water containing detergent into the washing tub 5 (water tank 3) (step S6). This water supply is performed until the water level in the washing tub 5 reaches a predetermined water level slightly lower than the partition plate 50 (step S7). When the predetermined water level is reached (Yes in step S7), the water supply valve is once stopped (step S8).

Then, the stirring body 6 is intermittently driven to rotate forward and backward (step S9). At this time, the water level in the washing tank 5 is relatively low and has not reached the partition 50, but the rotation of the stirring body 6 can vigorously stir the water and the detergent to fully dissolve the detergent and accelerate the dissolution of the detergent, thereby quickly bubble. And, by the action of the pump blade 36 of the agitator 6, the washing water can be raised (pumped) to the water channel 37, and the shower water flow can be discharged into the washing tub 5 from the discharge port 37a.

At this time, if the clothing W is made of a material with high hydrophobicity such as wool, the clothing W may float on the partition 50 and the washing water is difficult to penetrate. However, since the washing water has not reached the partition 50 at this time, it is neatly placed Before the clothes W on the partition 50 float and move to be stacked, the clothes W on the partition 50 are sprayed with shower water. Thereby, the laundry W can be permeated with washing water before the actual start of washing, and deformation of the laundry W due to floating and uneven washing can be suppressed.

After the forward and reverse rotation of the stirring body 6 in step S9 is performed for a predetermined time (for example, tens of seconds), the water supply valve 20 is opened to resume water supply (step S10 ). When the water level in the washing tank 5 reaches the set water level (water level higher than the partition 50) (Yes in step S11), the water supply valve 20 is closed (step S12). Thereafter, the agitator 6 is continuously driven for a predetermined time in forward and reverse rotation (step S13) to perform a washing operation (step S14).

As shown in Figure 7, by the driving of the stirring body 6, the water flow generated by the convex part 6a of the stirring body 6, as shown by the arrow A, rises through the water hole 53 provided on the dividing plate 50, and flows on the dividing plate 50. A swirling water flow is generated on the upper peripheral portion. The rotating water flow and the washing water drawn from the pump chamber 35 through the water passage 37 are sprayed on the clothes W from the discharge port 37a, thereby performing washing by a pressure flushing method.

By performing the washing course of the soft washing course as described above, the clothes W not only do not directly contact the agitator 6 , but also suppress friction with the partition plate 50 , and the clothes W can be washed by the swirling water flow. For example, soft sweaters, etc., can be washed while rotating without deforming them. Accordingly, it is possible to perform gentle washing while suppressing damage to the clothes W. In addition, a high washing effect can be obtained on the entire clothes W by the swirling water flow and the pressure washing effect of the washing water (shower water flow) sprayed from above.

In this way, according to the present embodiment, a detachably mounted partition 50 is provided in the washing tub 5 provided with a water passage hole 53 through which washing water passes, and clothes W are placed on the partition 50 installed so that washing water can pass through. Therefore, the soft washing process can be performed, thereby preventing damage to the clothes W when washing the fragile clothes W, and improving the cleaning effect, which can obtain excellent results.

In addition, in this embodiment, the inner handle portion 59 provided on the plate-like member 51 constituting the partition 50 is disposed near the half-folded portion 58 of the plate-shaped member 51 , so that the user's fingers can be inserted into the partition installed on the washing tub 5 . The partition board 50 can be easily removed from the sink 5 by lifting the partition board 50 upward through the inner handle portion 59 on the board 50 .

That is, when the user inserts fingers into the inner handle portion 59 and lifts up the partition plate 50 , the double-folded portion 58 of the partition plate 50 moves upward as a fulcrum in a compressed state with the hook 54 fitted in the pressure receiving portion 57 . At this time, since the inner handle portion 59 is provided closer to the folded portion 58 constituting the operating point (action point) than the edge portion of the plate-shaped member 51 provided with the hook 54 as a fulcrum, it is possible to use a small Forcefully lift the folded portion 58 to remove the partition 50 from the sink 5 .

In addition, in the two plate-shaped members 51, the outer handle portion 60 is provided closer to the edge portion of the plate-shaped member 51 than the folded portion 58. Therefore, when installing the partition plate 50 in the washing tank 5, by placing The user's fingers, such as the index finger, middle finger, and ring finger, are inserted into the outer handle portion 60 provided on the two plate members 51 to easily maintain the partition plate 50 folded in half in a raised shape.

In addition, after inserting the raised partition 50 into the washing tub 5 until the hook 54 of the partition 50 faces the pressure receiving portion 57 of the washing tub 5 , use a finger not inserted into the outer handle portion 60 For example, by pressing down with the thumb the upper surface of the plate member 51 that is closer to the center (closer to the half-fold portion 58) than the outer handle portion 60, the partition plate 50 that is folded in half in a raised shape can be simply opened into a flat plate, thereby A fixed partition 50 is installed above the stirring body 6 .
