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. Since the washing articles move in accordance with the heart-type waterflow, the washing articles in the center portion of the heart-type waterflow are not sufficiently washedSUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a pulsator for a washing machine capable of preventing generation of a concentric waterflow such as a heart-type waterflow.In order to achieve the object, a pulsator for a washing machine according to an embodiment of the present invention comprises a base plate, a plurality of plate-shaped wings, a plurality of cover plates and a plurality of protrusion. The base plate is fixed to a shaft housing to be rotated according to a rotation of the shaft housing. The plurality of plate-shaped wings is radially and vertically fixed to the upper surface of the base plate so as to be rotated according to the rotation of the plurality of plate-shaped wings. The rotation of the plurality of plate-shaped wings forms a concentric waterflowing washing water. Each of the plurality0f plate-shaped wings has a multi-stepped edge. The plurality of cover plates is fixed on the multi-stepped edges of the plurality of plate- shaped wing s. Each of the plurality of cover plates is a disc-shaped plate having a hole in the center portion. The plurality of protrusions is radially and in a certain length formed on the upper surface of each of the plurality of cover plates the plurality of protrusions is rotated according to the rotation of the base plate to generate a waterflow of the washing water vertically oriented toward the top of the washing tub. Therefore, using the pulsator for a washing machine according to the present invention can generate an effect that prevent the tangling of washing articles by generating a vertically oriented waterflow to inhibit the generation of a concentric waterflow in the washing water. As well as generates another effect that performs washing of the washing articles sufficiently by floating the washing articles fully in the washing tub.洗衣机用波轮摘要 公开一种用于能够防止产生同心水流的洗衣机波轮，如向心水流。该波轮包括一个固定在轴套上的基板，多个被径向固定在基板的上表面上的板状叶片，用于在洗涤水中形成同心水流。多个板形叶片被固定在的多级边缘的盖板上，以及多个径向突起物按一定长度形成于每块盖板的上表面上，根据基板的旋转，使洗涤水产生朝洗衣筒顶部垂直运动的水流。一般适用于家用的洗衣机是一种利用洗涤水、洗涤剂等能很容易地除去含在洗涤物中污垢和其它杂质的装置。这样的家用洗衣机按洗涤方法可分为水涡流式洗衣机、水搅拌式洗衣机、或滚筒式洗衣机。在这种情况下，水涡流式洗衣机是一种靠洗涤物间摩擦清洗洗涤物的洗衣机。就是说，如果安装在洗衣筒底部上的搅拌器旋转时，产生心形水流，使洗涤物相互接触，从而对洗涤物品进行洗涤。水搅拌式洗衣机是一种靠洗涤物在洗涤搅拌器和洗衣筒壁上的撞击来清洗洗涤物品的洗衣机。就是说，当安装在洗衣筒中央的洗涤搅拌器有规律地转动时，洗涤搅拌器外表面的搅拌凸出物产生水流，从而使洗涤物撞击在水搅拌器和洗衣筒的壁上。通过洗涤物撞击在水搅拌器和洗衣筒壁上来对被洗涤物品进行清洗。另一方面，滚筒式洗衣机则是一种靠洗涤物向上和向下作圆周运动来洗涤被洗涤物品的洗衣机。滚筒式洗衣机具有与洗涤筒平行安装的圆柱滚筒。圆柱形筒包括多个孔和多个凸起。当圆柱筒转动时，多个凸起使洗涤物向上运动，再靠地球引力作用使向上运动的洗涤物下落。采用上述方法，洗涤物中的污渍被洗涤干净。上述提到的洗衣机中，水涡流式洗衣机一般作家庭使用。参见图1和图2，详细说明水涡流式洗衣机。 图1是一个传统洗衣机的示意图，图2为图1洗衣机的波轮的示意图。如图1所
