A vibration-damping mounting structure for a motor and a range hood having the same
A technology for installation structures and range hoods is applied to motor vibration reduction installation structures and range hoods. It can solve the problems that affect the high-quality home use of the range hood, the large vibration of the volute, and the poor rigidity of the volute, so as to achieve good vibration reduction effect, stable operation, low vibration and noise.

Problems solved by technology
In this case, the motor is equivalent to being fixed on the extension part of the whole machine. Due to the poor rigidity of the volute itself, the volute itself will vibrate greatly when the motor is running, which in turn makes the motor installed on the volute Generate greater vibration, which will inevitably increase the noise and affect the high-quality home use of the range hood

Embodiment Construction
[0027] The present invention first aims at the defects in the motor installation structure of range hoods in the prior art, and proposes an improved motor vibration-damping installation structure, the schematic diagram of which can be found in Figure 1-6 .
[0028] As shown in the figure, the motor vibration-damping mounting structure of the present invention includes motor brackets 2, 3, vibration-damping devices and fasteners (not shown, such as screws). Wherein, the involved motor 1 includes a mounting flange 101, and according to specific usage, the motor mounting flange 101 can be located at the front end, the rear end, or the middle part of the motor body (as shown in the figure). The vibration damping device is arranged between the motor brackets 2, 3 and the mounting flange 101 of the motor, and the fastener fastens the motor bracket, the mounting flange of the motor and the vibration damping device together.
[0029] Specifically, as an improvement on the first asp...

The invention discloses a vibration damping installation structure for a motor, which comprises a motor bracket, a vibration damping device and a fastener, the vibration damping device is arranged between the motor bracket and the mounting flange of the motor, and the tightening Firmware fastens the motor bracket, the mounting flange of the motor and the vibration damping device together, wherein the motor bracket includes a first bracket and a second bracket, and the fixing of the first bracket and the second bracket The ends are fixed spaced apart from each other in the axial direction of the motor. In the motor installation structure of the present invention, the motor is respectively fixed to two different positions or components through two brackets, so that higher installation stability and good vibration reduction effect can be obtained.
Description
technical field [0001] The invention relates to the fixed installation of a motor, in particular to a vibration-damping installation structure of a motor. The invention also relates to a range hood. Background technique [0002] In electrical equipment with a motor, the installation of the motor is very important. In addition to the need for firm installation, it is also necessary to prevent the noise and vibration of the motor during operation. Taking the range hood as an example, the motor of the existing range hood is mainly installed on the volute through a motor base or a motor bracket, and the vibration is damped by a rubber pad, and the volute is then installed on the wind cabinet. In this case, the motor is equivalent to being fixed on the extension part of the whole machine. Due to the poor rigidity of the volute itself, the volute itself will vibrate greatly when the motor is running, which in turn makes the motor installed on the volute Greater vibration will be...
