Impeller module, integrated motor and household appliance

Abstract

The present invention discloses an impeller module, an integrated motor and a household appliance. The impeller module comprises: a fan cover having an exhaust inlet and an air supply outlet; an impeller configured to suck fluid from the outer portion of the fan cover through the exhaust inlet into the fan cover, wherein the impeller is rotationally arranged in the fan cover and is adjacent to the exhaust inlet; a guide disk arranged in the fan cover and is adjacent to the air supply outlet, wherein a drainage air channel communicated with the exhaust inlet and the air supply outlet is limited between the outer wall surface of the guide disk and the inner wall surface of the fan cover; and a guide vane wheel configured to lead the fluid sucked by the impeller into the drainage air channel, wherein the guide vane wheel is arranged in the fan cover and is arranged around the impeller, and the outer wall surface of the guide disk is connected with the guide vane wheel and is tangent to the outer wall surface of the guide vane wheel. The impeller module has high efficiency.

Description

technical field [0001] The present invention relates to the technical field of motors, in particular to an impeller assembly, an integrated motor with the impeller assembly and a household appliance with the integrated motor. Background technique [0002] When the motor in the related art runs at a high speed, due to a large temperature rise, the bearings and structural parts of the motor will be deformed, resulting in high noise, low performance, low reliability and short service life of the motor. For this reason, the impeller assembly is usually used to cool down the motor. However, since there is a large nest area between the vane guide wheel and the air supply port of the impeller assembly, it is easy to cause eddy current loss, resulting in low efficiency. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes an impeller assembly, which ...
