中英文翻译PULSATOR FOR A WASHING MACHINEABSTRACT Disclosed is a pulsator for a washing machine capable of preventing generation of a concentric water flow such as a heart-type water flow. The pulsaltor includes a base plate fixed to the shaft housing, a plurality of plate-shaped wings radially fixed to the upper surface of the base plate and for forming a concentric water flow in the washing water. A plurality of cover plates fixed on the multi-stepped edges of the plurality of plate-shaped wings, a plurality of protrusions radially and in a certain length formed on the upper surface of each of the plurality of cover plates and for generating a water flow of the washing water vertically oriented toward the top of the washing tub by being rotated according to the rotation of the base plat. In general a washing machine for home use is a device which can easily remove dirt and other foreign materials contained in washing articles, using washing water, detergents and so on.Such a washing machine for home use can be classified as a water whirlpool-style washing machine, a water stirring- style washing machine, or a drum-style washing machine by washing methods.In this case, the water whirlpool-style washing machine is a washing machine which washes washing articles by friction among the washing articles. That is, if a pulsator mounted on the bottom of the washing tub is rotated. A heart-shaped water flow is generated to cause contact of the washing articles with each other, so that the washing articles are washed. The water stirring-style washing machine is a washing machine which washes washing articles due to the striking of the washing articles against the washing agitator and the wall of the washing tub. That is, if the washing agitator mounted on the center of the washing tub is regularly rotated the stirring prominence formed on the outer surface of the washing agitator generates a waterflow so that the washing articles strike against the water agitator and the wall of the washing tub. The washing articles are washed by the striking of the washing articles against the water agitator and the wall of the washing tub.On the other hand, the drum-style washing machine is a washing machine which washes washing articles by moving the washing articles up and down in a circular motion. The drum-style washing machine has a cylinder-type drum mounted in parallel with the washing tub. The cylinder-type drum includes a plurality of holes and a plurality of prominences. When the cylinder-type drum is rotated, the plurality of prominences move the washing articles up and the moved-up washing articles drop down due to the gravity of the earth. In the way mentioned above the dirt within the washing articles is washed clear. Of the washing machines mentioned above, the water whirlpool-style washing machine is generally used for home use.The water whirlpool-style washing machine is explained below in detail referring to FIG. 1 and FIG. 2.FIG. 1 is a schematic view of a conventional washing machine and FIG. 2 is a schematic view of the pulsator of FIG. 1. As shown in FIG. 1, a motor 4, which generates a rotating force with an input of external electric power, is mounted on the outer bottom of the reservoir 1. A shaft housing 5 for transmitting the rotating force of motor 4 is connected to the motor 4 through pulleys 21 and a pulley belt 22. A rotating force of shaft housing 5 is transmitted to a pulsator 3 through a shaft 7 0f shaft housing 5. Shaft 7 is protruded inside a washing tub 2 through the bottom of reservoir 1. On the upper portion of shaft 6 pulsator 3 is fixed. As shown in FIG. 2, pulsator 3 has a circular-shaped plate 8, and a plurality of wing prominences 6 radially formed on the upper surface of circular-shaped plate 8. In such a conventional washing machine, motor 4 is rotated with an input of electric power. The rotation of motor 4 is transmitted to shaft housing 5 to thereby rotate shaft7. When shaft 7 is rotated circular-shaped plate 8 0f pulsator 3 is rotated accordingly. The plurality of wing prominences formed on circular-shaped plate 8 is rotated. The rotation of the plurality of wing prominences 6 rotates the washing water and the washing articles. That is, the rotation of pulsator 3 generates a centrifugal force of the washing water. And the centrifugal force moves the outer periphery portion of the washing water upwards while moving the inner portion of the washing water downwards therefore. A heart-type water flow is formed in the washing water. Such a heart-type waterflow which is a concentric waterflow causes the washing articles to be gathered in the center thereof and to make contact with each other so as to remove the dirt of the washing articles.In the washing of washing articles by the heart-type waterflow, the washing articles in the center portion of the heart-type waterftow become tangled with each other to thereby deteriorate the effectiveness of the washing.
