Washing machine and motor fan impeller

Abstract

The embodiment of the invention discloses a motor fan impeller and a washing machine comprising the motor fan impeller. The motor fan impeller comprises a round sheet and multiple blades perpendicular to the end face of the round sheet, wherein each blade extends along a corresponding first arc section, the first arc sections are arranged towards the edge of the round sheet from the center of the round sheet, and the rotating directions of the multiple blades are the same. A large number of experiments show that the negative pressure at the center of the motor fan impeller in the embodiment is smaller than the negative pressure at the center of a fan impeller in the prior art, the difference of the pressure of the interior and the pressure of the exterior of a motor is large, and therefore air around the motor can be driven to rapidly flow, the air suction amount becomes large, and the heat dissipation efficiency of the motor is improved.

Description

technical field [0001] The invention relates to the technical field of washing machines, and more specifically, to a washing machine and a motor wind impeller. Background technique [0002] In order to improve the heat dissipation efficiency of the motor in the washing machine, a motor wind impeller is usually arranged on the motor. [0003] see figure 1 The motor wind impeller includes a circular thin plate 1, a blade 2 formed on the circular thin plate 1 and perpendicular to the circular thin plate 1, and the edge of the circular thin plate 1 forms a cut structure 3 of a circular arc structure. Although the motor wind impeller with this structure can improve heat dissipation efficiency, when the washing machine performs dehydration operation, the motor runs at high speed, and the motor wind impeller with the above structure cannot meet the heat dissipation requirements of the motor. [0004] Therefore, how to improve the heat dissipation efficiency of the motor has becom...
