Low-noise anti-winding impeller washing machine

Abstract

The invention discloses a low-noise anti-winding impeller washing machine. The low-noise anti-winding impeller washing machine comprises a machine shell, an outer barrel, an inner barrel and impellers; a first permanent magnet is arranged at the upper end of the outer side of the outer barrel; a second permanent magnet is arranged on the inner side of the machine shell; and the first permanent magnet and the second permanent magnet are arranged in a magnetic opposite mode. The impellers comprise an upper impeller and a lower impeller; the upper impeller comprises an upper impeller disc, an upper middle boss and upper washing ribs are arranged on the upper surface of the upper impeller disc, and an opening is formed in the top of the upper middle boss. The lower impeller comprises a lower impeller disc, the upper surface of the lower impeller disc is provided with a lower middle boss and lower washing ribs, and the lower washing ribs can make contact with the lower surfaces of the upper washing ribs. A flow channel is defined between the lower middle boss and the lower surface of the upper middle boss. And the lower impeller disc is provided with a flow channel port. Annular reinforcing ribs and impeller blades are arranged on the lower surface of the lower impeller disc, the flow channel opening is formed in the radial outer side of the outermost annular reinforcing rib, and the impeller composed of the impeller blades meets the condition that when the impeller rotates forwards or backwards, water flows upwards or downwards to flow through the flow channel.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a low-noise anti-winding pulsator washing machine. Background technique [0002] Washing machines can be divided into three types: stirring type, drum type and pulsator type. [0003] figure 1 A partial sectional view of a conventional pulsator washing machine is shown. see figure 1 , the box body 1 is provided with a cylindrical outer cylinder (not shown) for containing water, and an inner cylinder 2 is rotatably arranged in the outer cylinder, and a plurality of can be arranged on the side wall of the inner cylinder 2 Holes 2a for water to flow between the inner and outer cylinders. A pulsator 3 is provided on the inner bottom of the inner cylinder 2, and the pulsator 3 is connected to a driving shaft (not shown), and the driving shaft is driven by a motor (not shown). The upper surface of the pulsator 3 is provided with a plurality of washing ribs 3a protruding upward ...

AI Technical Summary

Problems solved by technology

[0008] The technical problem to be solved by the present invention is to provide a low-noise anti-winding pulsator washing machine. On the one hand, during the washing process, the washing machine can generate a specific form of water flow by reversing its pulsator, which can effectively reduce the amount of laundry On the other hand, this washing machine can better solve the problems that the sponge layer of the existing pulsator washing machine is easily damaged, and because of the short buffer distance of the sponge layer, the vibration of the casing is large, and it is easy to generate noise.
