減少させることができなかつた。Configuration of conventional vacuum cleaners and their problems One of the peak noises generated by conventional vacuum cleaners is a sound at a frequency corresponding to the motor rotation speed (hereinafter referred to as n-sound). This noise is generated because vibrations generated by the unbalance of the motor are transmitted to the main body of the vacuum cleaner via a motor support device made of an elastic body, causing the main body to vibrate. Therefore, in order to reduce the noise, the unbalance of the motor can be reduced to reduce the generated vibrations, or the vibration transmission can be reduced to suppress the vibrations of the main body. However, reducing the former motor unbalance requires a significant increase in man-hours, which is not realistic. On the other hand, in order to reduce the latter vibration transmission, it is sufficient to lower the resonance point by reducing damping or decreasing 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, and as a result, when the fan is activated, it is compressed by negative pressure, which increases the spring constant and damping ratio due to the nature of rubber, making it difficult to manufacture. Even if they were made as soft as possible, they could not reduce the n sound.

Rubber packing 6 around the fan casing 4

When rotated, air is sucked in the direction of the arrow, creating negative pressure in the suction space 7, which applies force in the direction of lifting the fan motor 5, compressing the metal spring 3, and absorbing the upward force caused by this negative pressure. do. At this time, the rubber packing 6 also bends a little and takes on the upward force, but compared to the force that the metal spring 3 takes on, the force is almost negligible. Therefore, the transmission of the vibration of the fan motor 5 to the cleaner body depends on the characteristics of the metal spring 3, and the characteristics of the rubber packing 6 are hardly affected.

程度に迄下げることが可能となつた。Effects of the Invention As described above, according to the present invention, the support device is made of a metal spring which has a much smaller damping ratio than rubber and whose spring constant does not change with respect to the load. Compared to conventional support using rubber elastic bodies, vibration transmission is extremely small, and as a result, the sound pressure of the n sound is reduced from about 60 dB to about 40 dB.
It has now become possible to reduce it to a certain degree.
