Abstract

The invention relates to a vane wheel facilitating belt fixing. The vane wheel comprises a shaft sleeve, a belt pulley and a thin plate. The shaft sleeve is fixed at the upper end of the belt pulley, a through hole is formed in the shaft sleeve, a threaded through hole is formed in the cylindrical face of the shaft sleeve, protrusions are arranged on the inner side of the belt pulley, the thin plate is formed at the lower end of the belt pulley, a round disc is arranged at the center of the thin plate, a slice vane wheel body is arranged on the periphery of the round disc, vanes are vertically formed at the lower end of the slice vane wheel body, a reinforcing rib is arranged on each vane, and radiating holes are formed in the upper end of the round disc and the thin plate. A belt is well fixed in a groove of the belt pulley belt by means of matching of the protrusions to avoid slip of the belt. The radiating effect can be improved by means of the radiating holes and the slice vane wheel, so that a motor can be protected.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to a wind impeller convenient for fixing a belt. Background technique [0002] Currently, in the pulsator washing machines sold in the market, in order to ensure that the motor can fully dissipate heat during the working process of the pulsator washing machine, a wind impeller needs to be installed on the motor. The wind impeller not only helps the wave wheel washing machine motor to dissipate heat on the one hand, but also connects the belt through the upper pulley to drive the clutch to rotate. In order to improve the efficiency of belt rotation, the groove for fixing the belt in the pulley is a smooth curved surface, which causes the belt to slip easily and affects the normal use of the pulsator washing machine. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a wind impeller which is convenient for fixing the belt, and overc...
