[Examples of the Invention]

Example 1

1 to 5 are cross-sectional views showing the electric washing machine of the present invention, a perspective view of an upper cover, a perspective view of a balancer, a top view of a rotary blade, and a perspective view of a back side, respectively. In the drawing, reference numeral 1 denotes an outer box, numeral 2 denotes an outer tank provided in the outer box 1, numeral 3 denotes a motor 4 and a reduction gear 5) a driving part consisting of the same, (6) is a washing and dewatering tank rotatably provided in the outer tank (2), (7) is provided on the upper peripheral edge of the washing and dewatering tank (6) and spiral ribs (7a) ), The balancer formed on the entire inner circumferential surface, (8) is a dewatering hole formed in the wall surface of the washing and dewatering tank (6), (9) the laundry contained in the washing and dewatering tank (6), and (10) Rotating blades provided on the inner bottom of the dehydration tank (6), (11) a plurality of rotary wing vent holes formed in the rotary blade (10), (12) rotating blades of the inner bottom of the washing and dehydration tank ( A drain and exhaust hole formed at a lower position of 10, 13 is an upper cover having a lid 14 provided in the upper opening of the outer box 1, 15 is an upper cover 13 for controlling the drive unit 3 of mine Provided the control unit, 16 is the inlet port, 17 is formed in the top cover 13 is an exhaust port formed in the top wall after the outer box (1). In addition, the arrow in a figure shows the flow of air (wind).

In the electric washing machine configured in this way, first, the washing process, the rinsing process, and the dehydration process are performed. After the dehydration step is completed, the washing and dewatering tank 6 is rotated. The centrifugal force is generated by the rotational action of the washing and dewatering tank 6, and outside air is sucked into the washing and dewatering tank 6 from the inlet 16 located above the washing and dewatering tank 6. At this time, the balancer 7 forms a spiral rib 7a as shown in FIG. 3 on the entire inner circumferential surface, so that the outside air taken in from the intake port 16 flows along the spiral rib 7a. It becomes easy and the outside air becomes easy to inhale. The outside air introduced in this way comes into contact with the laundry 9 to vaporize the water contained in the laundry 9, thereby reducing the moisture content of the laundry 9. The outside air containing moisture flows out of the washing-and-dehydrating tank 6 from the rotating wing vent holes 11 formed in the rotary blade 10 shown in FIG. 4 to the inside of the washing-and-dehydrating tank 6. It passes through the drain and exhaust hole 12 formed in the bottom part, and it goes to the outside from the discharge port 17 provided in the upper rear wall surface of the outer box 1 through the clearance gap between the washing and dehydration tank 6 and the outer tank 2. There are discharged (arrow of thin line in FIG. 1) and discharged directly from the exhaust port 17 in the washing and dehydrating tank 6 (arrow of thick line in FIG. 1).

Next, rotation control of the washing | cleaning and dehydration tank 6 is demonstrated. The outside air can be introduced by the same rotational speed and rotational direction as in the normal dehydration step. However, if the rotational speed of the washing and dewatering tank 6 is varied or the rotational speed is changed, Pressure is generated in the dehydration tank 6 so that outside air can be easily introduced, and strength and weakness can be imparted to the flow of the outside air, thereby facilitating evaporation of water in the laundry 9. In addition, if the rotational direction is changed from side to side, the flow of the introduced outside air is changed to unwind the laundry 9 so that the laundry 9 can be brought into contact with the outside air evenly.

Further, the rotary vanes 10 are rotated during the rotation of the washing / dehydrating tank 6 or after completion of the rotation of the washing-and-dehydrating tank 6 so as to scrape off the laundry 9 in the washing-and-dewatering tank 6. It is also possible to bring the laundry (9) into contact with the flow (wind) of the outside air evenly introduced.

That is, by providing the inlet 16 and the drain and exhaust hole 12 at the inner bottom of the upper cover 13 and the washing and dewatering tank 6, the outside air is rotated by the washing and dewatering tank 6, respectively. The air flows from the intake port 16 toward the drain and exhaust hole 12, and furthermore, the outside air is more likely to flow by the ribs 7a provided in the balancer 7, and the water in the washing and dehydration tank 6 The air (wind) of air comes into contact with the contained laundry 9 effectively.

In this way, by bringing the outside air into the air flow in contact with the laundry (9) containing moisture in the washing and dehydrating tank (6), the water in the laundry (9) can be vaporized and evaporated in the same manner as when the laundry is dried outside. Can be. And the laundry 9 is stirred by rotating the rotary blade 10 during the rotation of the washing and dewatering tank 6, so that the water in the laundry 9 can be evenly vaporized and removed.

By drying the laundry 9 after performing such an operation for a predetermined time, the laundry 9 can be dried faster than the dry laundry as it is. For example, although it depends also on the quantity of laundry, the temperature / humidity of a place to dry, etc., as shown in the drying characteristic diagram of FIG. 6, when 8 kg of laundry 9 is washed and dried and dried (FIG. 6). Graph a) After drying, after drying, it takes 240 minutes to dry, but after the dehydration process, the flow of air (wind) caused by the rotation of the washing and dehydrating tank 6 is brought into contact with the laundry to vaporize water. Dried (graph b in FIG. 6) can be dried in 160 minutes with 2/3 of time to dry.

In this way, since no drying apparatus or the like is used, the time required for laundry to dry can be shortened without incurring cost and complicated structure.

In the above embodiment, the laundry 9 containing moisture after the end of the washing step, the rinsing step and the dehydration step is brought into contact with the outside air as a flow of air, but the laundry containing the water after the end of the rinsing step is as described above. The same effect can be obtained also by making the air flow generate | occur | produce contact. Moreover, it is also possible to carry out contacting the outside air described in the said embodiment with the water | moisture-containing laundry as a flow of air as one process, and it is also possible to perform the outside air with respect to the laundry which performed the hand washing etc. By similar contact, the same effect can be obtained.

Example 2

In addition, although the intake port 16 is formed in the upper cover 13 in the said Example 1, if it is formed in the upper position rather than the opening part of the washing | cleaning and dehydration tank 6, it may be anywhere, and the rotary blade of the rotating blade 10 is carried out. When formed at the position of the drain and exhaust port 12 provided in the vent hole 11 or the inner bottom of the washing / dehydrating tank 6 and the linear top cover 13, the outside air is inside the washing / dehydrating tank 6 It is effective because it is sucked toward the exhaust port 12 in the bottom part. In addition, as shown in FIG. 8, when the air inlet 16 formed in the upper cover 13 is formed large and the cover 18 for opening and closing freely is attached, the air volume which is received by the big air inlet 16 is large. The cover 15 can be closed when the external air from the intake port 16 is not required, such as a normal washing process or a rinsing process.

As shown in FIG. 8, the air filter 19 is attached to the intake port 16 to prevent invasion into the washing and dehydration tank 6 such as various germs in the outside air and to receive clean outside air. When the odor of (9) can be suppressed and the air filter 19 is detachably formed, cleaning of the filter can also be performed comfortably (see Fig. 8).
