題があつた。Conventional structure and its problems Conventionally, this type of vacuum cleaner has a ring-shaped structure with a flange on the inside of the front end of the fan part of the fan motor unit in order to prevent vibrations from the fan motor unit from being transmitted to the vacuum cleaner body. The fan motor unit is vibration-proofly supported inside the vacuum cleaner body by covering the front vibration-proofing rubber and attaching the rear vibration-proofing rubber to the bracket of the motor part, and supporting each with the ribs of the vacuum cleaner body. It was common to have Furthermore, the collar of this front vibration isolating rubber also serves as a seal between the intake and exhaust air of the fan motor unit by coming into contact with the partition plate of the vacuum cleaner body. For this reason, the suction force of the fan motor unit is applied to the collar of the front anti-vibration rubber, and this force reaches a maximum of 10 kg, so the collar cannot be made very soft, and on top of that, the rubber is compressed. The anti-vibration effect of this flange was significantly reduced, and the vibration of the fan motor unit was easily transmitted to the vacuum cleaner itself, generating a loud noise of nearly 400Hz, causing discomfort to the user. .

いでいる。 A ring-shaped vibration isolating rubber 18 is attached to the outer periphery of the casing 6 of the fan section 2 of the fan motor unit 1, and elastically supports the fan section 2 on the cleaner main body 19 in the radial direction. A vibration isolating rubber 18' is attached to the housing section 14 of the bracket 12 on the opposite side of the fan of the motor section 3, and elastically supports the motor section 3 on the cleaner body 19. One end of a rubber thin, substantially cylindrical skirt-shaped seal 22 is fitted into the ventilation hole 21 of the fan-side main body partition plate 20 of the vacuum cleaner main body, and the other end is fitted into the air intake hole 4 of the casing 6 of the fan motor unit 1. The exhaust gas from the fan motor unit 1 is prevented from circulating to the intake hole 4 by closely adhering to the surroundings.

The other end of the support rod 25 is fixed with a substantially hemispherical retainer 28 through a washer 27 having a hole 26, and the support rod 25 is inserted into the groove 30 of the bracket-side main body partition plate 29 as shown in FIG. By doing so, the fan motor unit 1 is connected to the vacuum cleaner main body 19.
It is supported in the axial direction. In addition, the support rod 25
The spherical surfaces of the substantially hemispherical retainers 24 and 28 fixed to the housing part 14 and the outer surface of the washer 27 are respectively formed. Further, the retainers 24 and 28 may be formed by molding the support rod 25.

Only air collects in fan motor unit 1.
It passes through and is exhausted from the main body exhaust hole 33.

る。 During driving, the fan motor unit 1 vibrates as shown in FIG. 5 due to the unbalance of the impeller 7 and rotor 17. That is, since it vibrates in a rocking mode, the axial component at the outer circumferential portion of the casing 6 is large, and the center of the rotating shaft of the anti-fan side bracket 14 does not vibrate in the axial direction at all.

分な防振効果を得る事ができる。 In the embodiment of the present invention, since the axial support is performed at the center of the rotation axis of the anti-fan side bracket 14, which has no axial vibration component, the fan motor unit 1 is attracted to the fan side main body partition plate 20. This suction is prevented, and no vibrations are transmitted through this support. Therefore, the fan side main body partition plate 2
Since the seal 22 fitted at 0 does not need to support suction force, it can be made sufficiently soft, and for the same reason, no vibrations are transmitted. Furthermore, regarding vibration transmission in the radial direction of the housing portion 14 of the anti-fan side bracket 12, the support rod 25, which has substantially hemispherical retainers 24 and 28 at both ends, has no radial restraining force. No vibrations are transmitted. Further, the vibration isolating rubbers 18, 18' need only support the own weight of the fan motor unit 1, and a practically sufficient vibration damping effect can be obtained.

きるものである。Effects of the Invention As described above, the vacuum cleaner of the present invention is capable of axial support with almost no vibration transmission by supporting the center of the bracket with a support rod provided with approximately hemispherical retainers at both ends. This makes it possible to greatly reduce the vacuum cleaner noise caused by the vibration of the fan motor unit.
