Abstract

The invention discloses a buoyancy type washing machine impeller capable of lifting and washing, comprising a wave disc and a plurality of ridgeplates which are arranged on the upper surface of the wave disc; each ridgeplate comprises a ridgeplate matrix which is arranged on the upper surface of the wave disc; the inside of the ridgeplate matrix is hollow and an opening is arranged on the upper surface of the ridgeplate matrix; a groove is formed by the opening and the hollow inside; a ridge beam is arranged inside the groove; the ridge beam can be entirely lifted and descended from the opening, and lifting means can be that the ridge beam is floated off under water by a hollow structure and / or materials of the ridge beam and also can be that the ridge beam is supported by a spring which is arranged inside the groove of the ridgeplate matrix and up-vertically connected with the groove. The structure is automatically arranged on a lifting position when water level is high, and barrier mechanisms are correspondingly arranged on side faces of ridge beams and side faces of grooves in order to increase resistance torsion of water on resisting rotation of the impeller. Moreover, a part of the ridge beams is guaranteed to be always arranged inside the grooves. And the structure is pressed down by the clothes and arranged on a descending position when the water level is low and completely enters into the inside of ridgeplate matrixes, thereby capability of lifting of the impeller is realized, and the washing machine simultaneously has functions of an impeller washing machine and an agitator washing machine.

Description

technical field

[0001] The invention relates to a laundry pulsator for a washing machine, in particular to a buoyancy washing machine pulsator which can be lifted and lowered for washing. Background technique

[0002] Traditional agitator washing machines use a stirring rod to turn the laundry back and forth during the laundry process to improve the effectiveness of the washing machine for cleaning clothes. The washing machine has a stirring bar arranged in the center of the vertical shaft type inner tub, and the inner tub is rotatably suspended in the outer tub of the washing machine. The stirring rod protrudes upwards from the center of the bottom wall of the inner barrel and generally its height is substantially lower than the height of the inner barrel balance ring. A stir bar generally includes a central column, a base plate and a plurality of blades. During the washing process, the driving mechanism of the washing machine drives the stirring rod to rotate back and fo...

Embodiment Construction

[0035] The pulsator described in the present invention is a modified pulsator, and the pulsator can be of any size, as long as it can be assembled in the inner tub of the washing machine, and the optimal size of the pulsator matches the bottom size of the tub of the washing machine.

[0036] Such as Figure 2 to Figure 6As shown, the modified pulsator of the present invention includes a wave plate 1 and a plurality of ridge plates 2 arranged on the upper surface of the wave plate 1, and each ridge plate 2 includes a ridge plate base 3 arranged on the upper surface of the wave plate 1, The interior of the spine base 3 is hollow and its upper surface is provided with an opening 31, forming a groove 32 with the hollow interior, and a spine 4 that can be lifted from the opening 31 is provided in the groove 32 to adjust the spine base 3 the height of.

[0037] Ridge board base body 3 interior hollow of the present invention can be " eight " font (referring to Figure 4 ), can als...
