Embodiment 1

[0028] Embodiment 1 is a volute fan of the present application. Such as Figure 1-4 As shown in , the volute fan includes: a volute 13, a motor 11 and an impeller 14, the volute 13 forms a housing chamber, and the impeller 14 is installed in the housing chamber, which becomes elongated in the axial direction of the motor axis 111 The plurality of blades 141 are formed in a cylindrical shape radially arranged at predetermined intervals with respect to the motor axis 111 . One end of the blade 141 is installed on the outer edge of the substantially circular rotating member 142 , and the other end of the blade 141 is installed on the annular support ring 143 to form an impeller air inlet inside. The rotating member 142 is fixed to the rotating shaft 112 of the motor at the center, and driven by the motor 11 , the impeller 14 rotates around the rotating shaft 112 . A side plate 132 of the volute is provided with a motor installation opening 133, and the rotating member 142 of th...

Embodiment 2

[0035] Embodiment 2 relates to an air conditioner. Using the volute fan in Embodiment 1 can effectively reduce the vibration and noise of the air conditioner, make the air conditioner run more quietly, with less vibration, and obtain better user experience .

[0036] Additionally, those of ordinary skill in the art will appreciate that the drawings provided herein are for illustrative purposes and are not necessarily drawn to scale.

Abstract

The invention aims to provide a volute fan. The technical problem that the vibration absorption effect of an existing volute fan is poor is mainly solved. The volute fan comprises a motor and an impeller. The impeller comprises a rotary piece and blades arranged on the outer edge of the rotary piece. The volute fan is characterized in that a rotary shaft of the motor is connected with the rotary piece of the impeller through a first vibration absorption device to drive the impeller to rotate. Due to the fact that the vibration absorption device is arranged, vibration and noise can be effectively reduced or eliminated.

Description

technical field [0001] The invention relates to the field of air supply mechanisms, in particular to a volute fan and an air conditioner. Background technique [0002] At present, most of the cabinets using centrifugal fan blades, the fan motor is installed on the motor mounting plate, and the shock absorption measures are four rubber pads at the feet of the motor. This kind of shock absorption method is to buffer the shaking of the fan blade and the vibration of the motor itself through the four machine foot rubber pads to achieve the purpose of shock absorption. However, the four rubber pads have limited ability to reduce vibrations. When the vibration exceeds the range of the rubber pads, the shock absorption will fail. Contents of the invention [0003] In view of this, the present invention provides a vibration damping device for a volute fan that can effectively reduce vibration and noise. [0004] For reaching this purpose, the present invention adopts following t...
