な限りの軟かさて作ったものでもｎ音を減少させること
ができなかった。Problems with the configuration of the conventional example: During vacuum removal, one of the peak noises generated is a sound with a frequency corresponding to the motor rotation speed (hereinafter referred to as n-sound). can be given. This n
The sound is generated because vibrations generated by an unbalanced motor are transmitted to the main body of the vacuum cleaner via a motor support device made of an elastic body, and the main body vibrates. Therefore, in order to reduce the noise, it is possible to reduce the vibrations generated by reducing the unbalance of the motor, or to suppress the vibrations of the main body by reducing the transmission of vibrations. However, reducing the former motor unbalance requires a significant increase in man-hours, which is not realistic. - To reduce the transmission of force and vibration of the latter, it is sufficient to lower the resonance point by decreasing the damping ratio or the spring constant, and if the configuration is devised, it can be realized with a fairly inexpensive device. Conventional vacuum cleaner motor support devices use an elastic body that doubles as an airtight device.
When the fan is operated, it is compressed by negative pressure, so due to the nature of rubber, its spring constant and damping ratio increase, and even if it is made as soft as possible, it has not been able to reduce the noise.
発明の目的
本発明はこのような従来の欠点を解消したもので、ｎ音
を減少して静音化面ですぐれた性能を発揮する真空掃除
機を提供するものである。OBJECTS OF THE INVENTION The present invention eliminates these conventional drawbacks, and provides a vacuum cleaner that reduces noise and exhibits excellent performance in terms of noise reduction.

的を達成したものである。Composition of the Invention The vacuum cleaner of the present invention includes a fan motor, a vibration isolator that supports the fan motor on the vacuum cleaner body, and an elastic body for maintaining airtightness, and the vacuum cleaner is made of a metal spring. It achieved its intended purpose.
実施例の説明 以下その実施例を添附図面とともに説明する。Description of examples Examples thereof will be described below with reference to the accompanying drawings.

６の特性は殆んど影響されない。In the figure, 1 is a vacuum cleaner main body having a suction port 2, and supports a fan motor 6' integrated with a fan casing 4 via a metal spring 3. And fan casing 4
A rubber backing 6 is attached around the vacuum cleaner body 1 and forms a suction space 7 in its entirety. now,
When the fan motor 5 is rotated, air is sucked in the direction of the arrow, the suction space 7 becomes negative pressure, a force acts in the direction of lifting the fan motor 6, the metal spring 3 is compressed, and the negative pressure causes an upward movement. absorb the power of At this time, the rubber backing 6 also bends a little and exerts an upward force, but the force is almost negligible compared to the force exerted by the metal spring 3. Therefore, the transmission of the image of the fan motor 6 to the vacuum cleaner body depends on the characteristics of the metal spring 3, and the characteristics of the rubber banking 6 are hardly affected.

た。Effects of the Invention As described above, according to the present invention, since the support device is constituted by a metal spring which has a much smaller damping ratio than rubber and whose spring constant does not change with respect to the load. , vibration transmission is extremely small compared to conventional support using rubber elastic bodies, and as a result, the sound pressure of the n sound is approximately 6
It has become possible to lower the noise level from 0 dB to about 40 dB.
