The patent No. is: 87206660 discloses a high-rib pulsator type washing machine in the Chinese patent literature, which is characterized in that the high-rib pulsator is arranged with a main rib higher than the center of the cross-shaped auxiliary rib, and is connected with the pulsator shaft Cylindrical fixing pin. the

Let's briefly introduce the pulsator with automatic swing structure:

As shown in Figure 1, the pulsator of the washing machine includes a pulsator main body 1', a fixed base 2', a blade 3', a rotating shaft 4', and a rotating sleeve 5'. The upper edge of the pulsator main body 1' has three fixed The seat 2' is fitted with a rotating sleeve 5' at the center of the pulsator main body 1', and a blade 3' is connected between the rotating sleeve 5' and the fixed seat 2' through a steering shaft 4', and the blade 3' can turn around The shaft 4' swings left and right, and the rotating sleeve 5' can rotate at a certain angle with the rotation of the main body of the pulsator and the change of the water flow. Although when the washing machine is working, the rotation direction of the impeller main body 1' is opposite to the deflection direction of the blades 3'. At this time, the deflection angle and action mode are just like boat oars, and large waves are set off in the washing tub, forming However, the rubbing effect between the pulsator and the laundry is weakened, and the laundry can only be washed by the impact of the water flow, and the washing effect is not ideal. the

There is also a "hand-rubbing" washing technology that allows the inner tub to rotate while the pulsator is reversing. Since the pulsator of the pulsator washing machine can only turn the clothes in the forward and reverse directions, it is easy to cause entanglement after a large amount of clothes and after washing for a long time; the clothes are turned and washed by the water flow, and the washing effect is poor and the water consumption is large. Recently developed a suspended double pulsator washing machine, which has two pulsators suspended on both sides of the inner tub, driven by the clutch transmission structure, rotating in the inner tub like wheels, thereby driving the clothes to turn over. Due to the rotation of the two suspended pulsators, it has the advantages of good flipping effect, no winding, and low wear in the drum washing technology, and at the same time realizes the advantages of high cleaning ratio of the pulsator washing technology. Another advantage of this technology is water saving. Since the inner and outer tubs are designed to be spherical, the bottom of the outer tub is small, and the highest water level only reaches 1/3 of the height of the pulsator for washing, thus achieving the purpose of water saving. the

In view of this, in order to effectively drive the clothes to rotate, the shape of the pulsator needs to be specially designed, and the technicians of the present invention have finally developed a novel suspended pulsator assembly structure. the

In the process of rotation, the boss 72 inserted in the socket hole 411 mainly drives the pulsator body 4. After long-term use, the boss 72 is easy to wear and fall off. At this time, the volume of the boss 72 can be enlarged. The size just coincides with the hole pitch of an insertion hole 411, or the boss 72 can also be made into more than one evenly distributed small boss, so that if a boss is worn out, there are alternate small bosses, such as As shown in the figure, 6 small bosses are arranged in an insertion hole 411. In addition, the bosses 72 can also be scattered, as long as their spacing coincides with the pitch of the insertion hole 411. Like this, the bosses 72 are inserted into each socket hole 411 respectively, so as to increase the working life of the pulsator bushing 7 . the
