As an option, the "rear end of the inner tub 1" means 1/7 position along the length of the inner tub 1 in the vertical direction (for example, a connecting portion between the inner tub 1 and the rotary shaft is a vertical length). It is used as a starting point) and thereafter. In another embodiment, depending on the installation of the washing machine inner tub 1, the outer tub 2 and other members, the specific position of the "rear end of the inner tub 1" is a position where the shake can be reduced. Good.

  Further, in this embodiment, the spacer may be the door 8 of the washing machine. When the door 8 of the washing machine is closed, the door 8 of the washing machine seals the front end opening of the inner tub 1 and the front end opening of the outer tub 2, and separates the front end opening of the inner tub 1 from the outer tub 2. A portion of the door 8 of the washing machine near the inner tub 1 is defined as an inner tub door 81. The inner tub door 81 is used to seal the front end opening of the inner tub 1 and A ring-shaped sealing member 9 is provided between the tank 1 and the tank 1. A sealing ring can be selected as the ring-shaped sealing member 9, and the sealing ring is fixed to the door 81 of the inner tank. A portion of the door 8 of the washing machine far from the inner tub 1 is defined as an outer tub door 82, and a door packing 13 is fixed to the outer tub door 82 to seal the outer tub 2 and the casing 14 of the washing machine. To be done. As an option, the door 8 of the washing machine is an integrated member for easy opening and closing of the door.

  As an option, the spacer may be a dedicated member for separating the inner tank 1 and the outer tank 2, for example, a stopper ring provided in a region between the front end of the inner tank 1 and the front end of the outer tank 2. And so on.

  As an option, in the present embodiment, a shower device is provided in the ring-shaped separation passage 6, and FIG. 3 is a schematic structural view of the shower device according to the present embodiment, in which the shower device 15 has a ring-shaped separation direction. It is a direction toward the inside of the passage 6. In the washing step, the inside of the ring-shaped separation passage 6 (including the side wall of the ring-shaped separation passage, the inner peripheral wall of the outer tank, and the outer peripheral wall of the inner tank) can be directionally washed away by the shower device 15. The cleaning effect was high, and the amount of water entering the inner tank 1 was reduced as much as possible. A water pipe connected to the shower device 15 may be provided for supplying water to the shower device 15.

  As an option, referring to FIG. 4, a flow guiding structure 12 is provided on the inner peripheral wall of the inner tank 1. In the present embodiment, the flow guiding structure 12 includes a plurality of protrusions, and the distribution of the protrusions has a spiral shape as a whole. In another embodiment, the flow guiding structure 12 may be a flow guiding groove or the like as long as it can guide the water in the inner tank 1 to the drain hole 5.

  Referring to FIG. 1, a first region B is formed inside the inner tank 1, a ring-shaped separation passage 6 forms a second region A, and the inner tank 1 and the outer tank 2 are separated from each other (the ring-shaped separation passage). A region other than the passage 6) forms a third region C, the first region B communicates with the second region A through the drain hole 5, the first region B does not communicate with the third region C, and the second region The area A also does not communicate with the third area C.

  Hereinafter, the operation process of the drum type washing machine of the present embodiment is as follows.

  At the time of washing, the door 8 of the washing machine is closed to close the inner tub 1, and tap water enters the ring-shaped separation passage 6 through the water supply pipe 10 and the water supply hole 3, and then through the drainage hole 5. The water entered the inside of the inner tank 1 to an appropriate level, and at this time, the water did not enter the third region C, but the water entered only the first region B and the second region A.

  When the water supply is completed, the motor drives the inner tub 1 to wash the inner tub 1 with a program having a fixed rotation time / stop time ratio.

  When the washing is completed, the drainage pump 111 is turned on to drain the water, and the water in the inner tub 1 enters the ring-shaped separation passage 6 through the drainage hole 5 and then to the drainage pipe 110 through the water discharge hole 4. Entered and discharged.

  During cleaning, tap water enters the ring-shaped separation passage 6 through the shower device 15, and the side wall of the ring-shaped separation passage 6 and the inner wall region and the inner tank of the outer tub 2 corresponding to the ring-shaped separation passage 6 The outer wall area 1 is washed away, and sewage is thoroughly washed out from the water discharge hole 4.

  When the washing is completed, the water is dehydrated in the inner tank 1, and the water is guided to the drain hole 5 by the flow guiding structure 12 in the inner peripheral wall of the inner tank 1, and then discharged through the ring-shaped separation passage 6 and the water outlet hole 4. To be done.

The rinsing process is repeated by repeating the above process until the washing is completed.
