Vibroisolating apparatus of vacuum cleaner
First Claim
1. A vacuum cleaner which includes a vibroisolating apparatus comprising:
- a suction motor adapted to be mounted within a vacuum cleaner body to generate suction force, said motor having a front surface and a rear surface;
a motor case disposed about the suction motor;
a vibroisolating ring provided at the front surface of the suction motor and a rear surface packing provided at the rear surface of the suction motor to absorb and inhibit vibrations generated by the suction motor from being transmitted to the motor case; and
a front surface packing arranged at an external front surface of the motor case to absorb and inhibit vibrations from being transmitted to the body of the vacuum cleaner, said front surface packing being provided at an inner surface of the packing with a buffering plate for buffering impact forces resulting from vibration of the suction motor.

Abstract
The present invention relates to a vibroisolating apparatus for a vacuum cleaner adapted to absorb and inhibit the vibrations generated in a suction motor from being transmitted to a body of the vacuum cleaner to thereby reduce the noise resulting from the vibration to a minimum, and at the same time, to improve the ease of assembling and to decrease manufacturing cost by way of a simplified construction. The vibration generated in the suction motor during operations is absorbed and inhibited at a front side of the motor by a vibroisolating ring which is tightly disposed between a front motor case and the suction motor. The vibration is also absorbed and inhibited at a rear side of the motor by the rear surface packing which is disposed between a rear motor case and the motor. The apparatus thereby reduces generation of noise resulting from the vibration of the suction motor to a minimum and provides for relatively silent operation of the vacuum cleaner.
