る。The operation will be described based on the above configuration. First, a small amount of water is supplied to the washing tub 3 to supply the detergent, and the stirring blade 7 is rotated for about 2 seconds to perform the detergent melting operation. In the stirring blade 7, the rotating force of the washing motor 11 is small and large.
It is transmitted to the wing shaft 6 via the belt 13 suspended on the reel 12A and rotates at a low speed. When the stirring blade 7 rotates, the washing water and the unmelted detergent pass through the communication hole 15 by the pump blade rib 19 and the recessed portion 4
The detergent is melted during repeated circulation of being sucked in and being discharged upward from the outer periphery of the stirring blade 7. In the present invention, the following phenomenon occurs due to the interaction between the flow regulating rib 8 and the pump blade rib 19. That is, when the outermost peripheral end of the flow regulating rib 8 is sucked into the pump blade rib 19, the outermost peripheral edge of the flow regulating rib 8 and the innermost peripheral edge of the pump blade rib 19 agitate in a draining state to form a turbulent flow. As a result, the melting of the detergent is accelerated.

いので、洗剤の溶融効果が悪い。FIG. 6 shows a case where a detergent is melted by the structure of the present invention and a stirring blade of our conventional structure (there is no communication hole for connecting the front and back sides, and the pump blade rib is formed over substantially the entire diameter of the back surface of the stirring blade). FIG. 4 is a detergent melting performance diagram comparing the molten state with the case of using the same). Although a circulating water flow can be generated in the conventional configuration, a large amount of washing water is sucked into the recessed portion to form a turbulent flow between the flow straightening rib 8 and the pump blade rib 19 as in the present invention, so that the detergent melting effect is poor.

も溶融作用が行われる。Next, after the detergent is melted, the washing tub 3 is supplied with water up to a predetermined washing water level and the washing process is started. The laundry is automatically inverted at a low speed and horizontally stirred by the main blade 14 to be washed, and at the time of stirring. Outer peripheral edge 14a of main blade 14 and auxiliary blade 1
6 acts as a washing plate, and the effect of scrubbing is added for washing. At the same time, a large amount of washing water is sucked toward the back side of the stirring blade 7 from a plurality of communication holes 15 provided in the central portion of the main blade 14, and is rectified outward by the rectification rib 8 protruding from the recess 4. Further, this wash water is pumped by a pump blade rib 19 to a circulation path (not shown) provided in the washing tub 3 and discharged from around the stirring blade 7 into the tub. At the time of this rotation, when sucked from the flow control ribs 8 by the pump blade ribs 19, a turbulent flow occurs due to stirring in a draining state as in the detergent melting work, and even if there is unmelted detergent, it is melted even during washing. The action takes place.

顆粒状の残留洗剤がなくなる。Therefore, even when using a recent compact detergent which is not particularly soluble, the detergent is melted in a short time by a turbulent flow formed by the flow straightening rib 8 and the pump blade rib 19 with a small amount of washing water before the start of washing. After the washing is finished, the laundry remains free of unmelted granular residual detergent.

変形しない。Further, during the washing operation, even if the stirring blade 7 is pressed by the load of the laundry, each reinforcing rib 18 formed on the back surface of the stirring blade 7 or the back surface of each blade 14, 16.
Since the rigidity of the blade base 7a is increased by 20, distortion or deformation of the blade base 7a does not occur due to scrubbing or the like. Further, when a non-crystalline polyolefin resin is used as the molding material of the stirring blade 7, the composition of the resin is less likely to be deformed than the polypropylene resin, and the effect of temperature when washing water is hot water is small and does not deform.

順になる。FIG. 7 is a performance graph showing the relationship between the "flexural modulus and temperature" of a typical resin forming the stirring blade 7. The three kinds of resins illustrated in the graph are compared. The allowable temperature when washing with hot water or dissolving the detergent used at the time of washing is 50 ° C to 60 ° C due to the temperature resistance of the washing machine and the performance of the detergent, so the resin that is difficult to deform is heat resistant ABS resin / polyolefin resin, then The order is the polypropylene resin used conventionally.

による撹拌翼の変形が防止できる。However, the heat-resistant ABS resin has a problem in durability against chemicals (deterioration due to influence of detergent), and has a problem in that material cost is high. Further, the polypropylene resin used conventionally has a good resistance to chemicals and a low material cost, but has a low allowable heat resistance temperature. Therefore, unless the allowable temperature of the washing machine is lowered to at least 45 ° C or lower, thermal deformation easily occurs. If the allowable temperature is not lowered, the stirring blade 7 is easily deformed and the cleaning performance is a problem. Therefore, a polyolefin resin that has good chemical resistance and does not easily deform is suitable for high water temperature and laundry. The deformation of the stirring blade due to the load can be prevented.

Therefore, the laundry residue after washing has no granular detergent residue.
