れてゆく。Therefore, the program timer is set to the washing process, and the water supply solenoid valve is energized and opened to supply water.
When water is supplied to the specified water level, the water level switch becomes a normally open contact.
At the same time, an overcurrent is applied to the drive motor via the B contact of the program switch and the auxiliary switch for automatic reversal, and the rotor blades (5) are rotated left and right alternately to complete the washing process. Start. Since the timer motor (to) is also driven, the program timer advances and the final dehydration process is automatically carried out according to the program shown in Figure 51.

である。The impeller (7) also rotates, and as a result of its pumping action, the liquid between the outer tank 11 (which is sucked into the pump chamber) and the dehydration tank (31) is pumped through the discharge port (to), the water pipe (to ), the water is sent to the dehydration tank 131 yen through the filter ring as shown by the arrow, and exits again between the outer tank 111 and the dehydration tank (3) through the dehydration hole (l), and the same cycle is repeated thereafter, but at this time, the impeller By the pump action, the amount of liquid sent to the dehydration $+g through the filter (to) is made larger than the amount of liquid flowing from the inside of the dehydration tank to the outside of the dehydration tank through the dehydration hole (2). The size and shape of the impeller (710 blades (6), the number and size of dehydration holes (2), etc. are set so that the water level (H) is higher than the water level (H) between the dehydration tank and the outer tank 113. And, as in this example, the rotor blade (!S
) rotates left and right alternately with the rotor at rest, while the rotor is at rest there is no pumping action of the impeller (η), so the difference between the two water levels (th) (H) gradually increases, The stopping time of the rotor is set so as not to be longer than the time it takes for this difference to disappear, and the water level inside the dehydration tank is always higher than the water level outside the dehydration tank.

の内周壁に付着し。However, in recent years, environmental pollution caused by neutral detergents used for washing has become a social issue.As a result, an increasing number of households are using powdered soap instead of neutral detergent. Soap scum adheres to the outer wall of the washing/dehydration tank and the inner wall of the outer tank.

いう問題があつた。This adhering soap scum changes color and eventually peels off, floating in the liquid between the outer tub and the washing and spin-drying tank.
There was a problem in that this soap scum entered the washing and dehydration tank through the numerous dehydration holes in the shoulder wall of the washing and dehydration tank, contaminating the laundry inside.

The pumping action of the impeller (7) sends the liquid between the washing and dehydrating tank (2) to the filter 4 installed at the top of the washing and dehydrating tank. The soap scum floating between ) is also sent to the filter (to) along with the liquid, where it is captured together with the lint, etc. contained in the liquid. 5)
Since the space is separated by a cover 〇, soap scum sucked into the pump dust (2) will not leak out from around the rotor blade 151 into the dehydration tank (3) by climbing over the cover (to). All of the water is sent to the filter (2) and captured securely (Also, due to the pump action of the imperani, the water level in the dehydration tank (H) is higher than the water level between the seven outer tanks of the dehydration tank (H). As a result, the water pressure inside the dehydration tank becomes higher than the water pressure between the dehydration tank and the outer tank, and the flow of water from the outside of the dehydration tank to the inside of the dehydration tank through the dehydration hole (21) is completely blocked, and the dehydration process is completed. It is possible to completely prevent soap scum from entering through the hole (21).Therefore, the laundry (AJ) in the dehydration tank will not be contaminated with soap scum, and the soap scum will be reliably removed by the filter (2). can.

い。By the way, in general, so that rinsing can be done in a short time and with a small amount of water, so-called foam removal dehydration is performed to remove the foam contained in the laundry in advance after the washing process and before starting the rinsing process. However, when performing dehydration to remove bubbles, if the liquid is not completely drained after the washing process and there is waste left in the outer tank or dehydration tank, foaming may occur due to the rotation of the dehydration tank. , the dehydration tank does not reach the specified rotation speed.

時間が長くなるという不都合が生じる。Therefore, looking at the dehydrating washing machine of the present invention, in order to prevent soap powder, a cover (2) is installed between the rotor blade (51) and the impeller (7).
The dehydration holes (21 are small in number and small in number) on the peripheral wall of the dehydration tank are separated so that the water level in the dehydration tank (H) is higher than the water level between the dehydration tank and the outer tank. Since the dehydration tank is small, it is difficult for the dehydration i4 +3) liquid to be drained to the outer tank.Therefore, in order to completely drain the liquid in the dehydration tank to remove bubbles and perform dehydration, it is necessary to take a long time to drain the water. , there arises the inconvenience that the driving time becomes longer.

を行なうようにしている。Therefore, in the present invention, after the washing process is completed, the dehydration tank (liquid still remains in the dehydration tank 31) is drained for a period of time long enough for all the liquid between the outer tank 11) and the dehydration tank (3) to disappear. The dehydration tank is rotated intermittently in the initial stage to forcibly discharge the liquid remaining in the dehydration tank to the outer tank, and when there is no liquid in the outer tank or the dehydration tank, the dehydration tank is rotated continuously This is done to remove bubbles and dehydrate.

関係なく連続して脱水槽は回＆される。That is, when the washing process is finished, the drain solenoid valve (to) is energized via the b contact of the program switch to drain water, and the liquid between the outer tank tll and the dewatering tank (3) is completely drained. When the dewatering tank is rotated, the drive motor (to) is driven via the normally open contact (to) of the water level switch (to), the Hatake contact of the program switch, and the auxiliary switch, and the dewatering tank is rotated.
As is clear from FIG. Therefore, the dehydration tank is initially accelerated during (!) time, during which the scale water in the dehydration tank is discharged to the outer tank, and after (!) time elapses, it decelerates and stops, and during this time (!! The liquid drained into the tank outside the time zone is drained outside the machine, and then accelerated again to remove bubbles and dehydrate.After 1 minute, the program switch is switched to the b contact, so the auxiliary switch - The dehydration tank will be cycled continuously regardless of the

Furthermore, since the dehydration tank is rotated with the liquid remaining in the dehydration tank, the T-balance of the laundry inside can be corrected, and abnormal vibrations are less likely to occur during dehydration.

のである。As described above, according to the present invention, the liquid between the washing/dehydration tank and the outer tank, which is sucked in by the pumping action of the impeller, is prevented from escaping from around the rotor blades into the dehydration tank by the cover (through). ), and the water level in the dehydration tank (H) is set higher than the water level (H) between the outer tank and the dehydration tank, so it can be used as a detergent.Also, after the washing process,
By intermittently rotating the dehydration tank and discharging the remaining liquid in the dehydration tank to the outer tank, it is possible to perform dehydration without taking a long time to drain the water, and at the same time, there is no abnormal vibration. It has a variety of excellent effects, such as improving the appearance of the skin.
