Problems solved by technology

For similar products using water pumps (such as dishwashers, etc.), different manufacturers usually have different requirements for the distance between the outlet centerline of the volute and the motor shaft; in the prior art, the helix wrap angle of the volute is usually less than 360 degrees, for the volute that requires a larger distance between the two, its radial dimension is usually larger, and the radial dimension of the corresponding motor bracket is also larger; therefore, suppliers need to produce different motor brackets for different manufacturers

Abstract

The embodiment of the present invention discloses a centrifugal device, which includes a motor, an impeller driven by the motor, and a spiral volute for accommodating the impeller, wherein the spiral wrap angle of the spiral volute is 360 to 460 degrees between. The embodiments of the present invention have the advantages of high efficiency, low noise and low cost.

Description

technical field [0001] The invention relates to a centrifugal device and a cleaning device, in particular to a volute and an impeller. Background technique [0002] The water pump includes a motor, an impeller driven by the motor, and a volute for accommodating the impeller. The volute is usually fixedly mounted on the motor bracket by a plurality of mounting parts arranged on its outer peripheral edge. For similar products using water pumps (such as dishwashers, etc.), different manufacturers usually have different requirements for the distance between the outlet centerline of the volute and the motor shaft; in the prior art, the helix wrap angle of the volute is usually less than 360 degrees, for the volute that requires a larger distance between the two, its radial dimension is usually larger, and the radial dimension of the corresponding motor bracket is also larger; therefore, suppliers need to produce different motor brackets for different manufacturers.
