Known technical solutions.

In General, a washing machine to wash at home is a device that can easily remove dirt and other foreign materials contained in items intended for washing using water, detergents and the like. Such washing machines for home use can be classified by means of washing on udovoletvorenie washing machines, with the mixing water or the washing machine drum. Vodorostvorima washing machine is a washing machine, washing items of Laundry by friction with one another. That is, if the pulsator mounted on the bottom of the washing baths, rotates the resulting water stream serdtseobraznoy form, causing the contacts of erasable objects with each other so that they are erased. The pulsator alternately rotated by a motor in both clockwise and counterclockwise and creates a flow of water for washing, causing friction for usteriana erasable objects.

Fig. 1 showing the agitating blades 102, located radially on the upper surface of the base 100. The upper surface of the base 100 has a slope from the center to the outer side at a certain angle.

In such a conventional washing machine base 100 pulsator 10 is driven into rotation by a motor. Accordingly, rotating and agitating blades 102, located at the base 100. Their rotation causes rotation of the water and wash items. That is, the rotation of pulsator 10 leads to the formation of centrifugal force in the water, which moves the outer peripheral part of the water up, and the inner part is down. Thus formed sincearly water flow in the washing machine. This sincearly water flow, which is concentric, leads to a concentration of erasable objects in the center and, thus, creates the contact between them, resulting in the removal of dirt from them.

However, in the conventional pulsator for a washing machine, the water is pushed out from the center to the outer part of the centrifugal force generated by the base 100, since the upper surface of the base 100 has a slope toward the center. At this time, since the center of the upper surface of the base 100 is below its outer side, drop water because tenagomysis in water, move to the center of the upper surface of the base 100 with water, so that the frictional force generated by the flow of water is not transmitted smoothly erasable subjects, which impairs the efficiency of washing. Moreover, since the agitating blades 102 are installed radially on the upper surface of the base 100, the flow of water, creating friction, formed by the agitating blades 102, on the outer side of the base 100 is stronger than in the center. Therefore, provided that wash the items are moved to the center of the base 100, they are very perekrikivayutsya by streams of water, which leads to their damage.

The second portion of water located in the first and second concave collecting tanks 361 and 362, forms a thread having a double bend, cast out towards the top of the base 300.

Because erasable objects pushed the first water stream falling out from the stirring blades 301 and the second water flow, rising outward from the first and second concave collecting tanks 361 and 362, erasable objects are not moved to the center of the pulsator 30, but rather unfold over the pulsator 30. Therefore, the operation sovesti 301 and the auxiliary agitating blade 302, located in the center of the concave collecting tank 36, commit cyclic reverse rotation forward and backward together with the rotation of the base 300. This leads to a circular flow of water in alternately reversing directions. At this time, the first flow of water, falling outward along the curved part 301a stirring blades 301, founder of the stirring blades 301 and the auxiliary blades 302 and, thus, forms a lower water flow. On the other hand, the second water stream, rising outward from the concave collecting tank 36, also breaks about three stirring blades 301 and the auxiliary agitating blade 302 and, thus, forms a stream located above the first. Therefore, the water flow is not homogeneous inside the washing bath 200, thereby improving the efficiency of washing.

The following describes the action of the pulsator for a washing machine in accordance with a second embodiment of the present invention. Laundry washing water fills the tub 200. When turning on the clamp (not shown), the rotation of the motor 202 is transmitted to the pulsator, leading it to a cyclically reversing the rotation. The rotation of the pulsator generates certain flows in the water washing bath. The first portion of water, located on the first two mixing blades 501, thrown outward toward the lower portion along the curved part 501a, beveled from the center of the base 500 to its outer edge. The second portion of water, located on the second agitating blades 502, thrown outward toward the lower portion along the curved part 502a, beveled from the center of the base 500 to its outer edge. On the other hand, the third portion of water, located on the first MAGNETOM collecting tank 55, thrown outwards towards the top of the base 500. The fourth portion of water, located on the second MAGNETOM collecting tank 56, thrown outwards towards the top of the base 500. Accordingly erasable objects are not looking to the center of the pulsator 50, which prevents them scrtach subsidiary stirring blades 507 and 508, from which they originate, does not coincide with the center 520 of the base 500, and shifted against him at a certain distance so that the erased items are not tightened to the center of the pulsator 50, which prevents them from twisting. Moreover, since the first agitating blade 501 more second agitating blades 502, a stronger flow of water is formed near the first agitating blades 501 and the second agitating blade 502 stimulates the flow is weaker. This leads to the fact that the flow of water in the washing tub is inhomogeneous, which leads to an increase mutual friction of erasable objects and improves the efficiency of washing.

As mentioned above, the pulsator for a washing machine in accordance with the present invention excites whirlpool type of water flow in the washing tub and smoothly transfers the force of friction from the flow of water to wash the items in a state where the flow of water in the washing tub is not homogeneous, which minimizes twisting of erasable objects and increases the efficiency of washing.
