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.

Claims

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.

4. A vibroisolating apparatus for a vacuum cleaner as defined in claim 1, wherein the vibroisolating ring is a many-sided shape.

2. A vibroisolating apparatus for a vacuum cleaner 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, wherein the motor case comprises a front case formed with an annular protrusion for supporting the vibroisolating ring, and a rear case adapted to be fastened to the front case and formed at one side thereof with a discharge outlet for discharging absorbed air; 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.

3. A vibroisolating apparatus for a vacuum cleaner as defined in claim 2, wherein the rear surface packing is provided with buffering covers and wherein, the rear case is provided with a plurality of inward extending protrusions adapted to be inserted into the buffering covers to prevent rotation of the motor with respect to the motor case.

5. A vibroisolating apparatus for a vacuum cleaner as defined in claim 2, further comprising a buffering member wherein the rear case is provided with a plurality of outward protrusions adapted to be inserted into the buffering covers to prevent transmission of vibrations to the vacuum cleaner body.

6. A vibroisolating apparatus for a vacuum cleaner as defined in claim 5, wherein the buffering member is formed at a periphery thereof with a plurality of buffering protrusions.

8. A vibroisolating apparatus for a vacuum cleaner as defined in claim 2, wherein the front and rear cases are integrally formed at inner sides thereof with front and rear buffering members.

7. A vibroisolating apparatus for a vacuum cleaner 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, wherein the rear surface packing is integrally formed with a buffering cover for being inserted over an external side of inward extending protrusions on the rear case and with a buffering ring for being tightly adhered to the suction motor; 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.
