より風を送る装置が開示されている。2. Description of the Related Art A conventional vibration damping structure of an air conditioner is described in, for example, Japanese Patent Application Laid-Open No. 4-52428. In this conventional example, the vibration of the fan or the motor is reduced by using a damping steel plate for an installation plate used when the indoor unit is installed on a wall, or by joining an anti-vibration rubber to the installation plate. It is prevented from being transmitted to the mounting plate or wall through the machine body. On the other hand, Japanese Patent Laying-Open No. 2-233914 discloses a device in which fans are attached to both ends of a motor shaft to send air.

とする。Considering that it is effective to provide vibration isolation near the vibration source, in the indoor unit, the fan driving motor is the vibration source. It cannot be said that a sufficient anti-vibration effect is obtained. ◆ On the other hand, when using a vibration-proof rubber for vibration-proof between the motor and the fan, two vibration-proof rubbers are used in the structure in which the fan is attached to both ends of the motor shaft as described in Japanese Patent Application Laid-Open No. 2-233914. Required and costly. If the fan is moved to one side of the motor in order to avoid this problem, the shaft length becomes longer and the natural frequency of the shaft system decreases, which is not preferable in terms of vibration characteristics. The object of the present invention is to provide an inexpensive vibration damping structure for an indoor unit that has excellent vibration insulation characteristics and good shaft system vibration characteristics.

現できる。The features of the present invention in an indoor unit will be described in comparison with other configurations. FIG. 5 shows a structure in which the motor shaft 38 protrudes from both sides, and the fan 6a shown in FIG. 4 is directly connected to the protruding side opposite to the protruding side previously connected. FIG.
FIG. 6 shows the results of frequency analysis of noise between the structure shown in FIG. 5 and the structure shown in FIG. In the case of the structure of FIG. 5 in which the fan is directly connected to the motor, there are some remarkable sharp peaks in the noise level. In particular, the peak seen at less than 1 kHz reaches as large as 30 dB. On the other hand, in the case of the structure shown in FIG. 4, such a peak is not recognized. The reason can be explained as follows. The motor 7 performs voltage control using a thyristor to change the rotation speed. At this time, the motor generates an external force having a frequency of 2, 4, 6, 8,... Times the power supply frequency [50 Hz, 60 Hz]. In a structure in which the fan is directly connected to the motor, the above-described external force directly vibrates the fan 6a, so that a large electromagnetic vibration sound is generated. Such electromagnetic vibration sounds are very annoying and must be avoided. One of the objects of the present invention is to reduce this electromagnetic noise, and this object is achieved by connecting all the fans to the motor via a vibration-proof joint. Therefore, according to the present invention, an air conditioner with small electromagnetic vibration noise can be realized.

果として騒音の大きさを増大させるからである。In addition to the electromagnetic vibration noise reduction described above, the indoor unit of the air conditioner is required to have low vibration of its housing and panel. This is because the vibration of the indoor unit housing and the panel excites the building in which the indoor unit is installed, thereby increasing the magnitude of noise.

は、図４におけるその距離よりも長くなっている。両者
の構造の差異が振動特性におよぼす影響を考えてみる。From such a viewpoint, the structure of FIG. 7 will be examined. The structure of FIG. 7 is sufficient from the viewpoint of reducing electromagnetic vibration noise because all the fans are connected to the motor via the vibration isolating joint. However, in this case, unlike the embodiment shown in FIG. 4, the bearing 3 is located farther away from the motor than the fan 6a farthest from the motor 7. That is, the distance from the motor having the structure in FIG. 7 to the bearing position is longer than that in FIG. Let us consider the effect of the difference between the two structures on the vibration characteristics.

動変位が最も大きいことが分かる。FIG. 8 shows a vibration model of the structure shown in FIG. 4 and its natural vibration mode. Here, m1 is the mass of the motor, m2 is the mass of the fan, k1 is the spring of the anti-vibration structure of the motor, and k2 is the spring of the anti-vibration joint. The thick solid line connecting these represents the axis. In addition, the inverted triangle in the figure means a bearing. The natural vibration mode of this vibration system is shown below the vibration model. That is, how the fan, the motor, and the shaft vibrate and displace are indicated by thick broken lines. From this figure, it can be seen that the fan 6c on the left of the anti-vibration joint k2 swings the most. Similarly,
FIG. 9 shows a vibration model having the structure of FIG. 7 and its natural vibration mode.
Shown in In FIG. 7, it can be seen that the vibration displacement at the position of the fan 6b is the largest.

設ける構造が最も固有振動数が高いことが分かる。The natural vibration modes shown in FIGS. 8 and 9 are vibrations in which the shaft is bent, and are generally called bending vibrations of the shaft. FIG. 10 shows the result of obtaining the bending natural frequency of the structure shown in FIGS. 4 and 7. The figure shows the natural frequency in the case of the structure of FIG. 7, and the figure shows the natural frequency in the case of the structure of FIG. The only difference between the structures shown in FIGS. 7 and 4 is the difference in the bearing position. FIG. 10 also shows the result when a bearing is further provided between the fans 6b and 6c. Here, the natural frequency on the vertical axis is shown in FIG.
Is a value normalized by the natural frequency of the structure of FIG. From this result, it can be seen that the bearing position according to the present invention, that is, the structure in which the bearing is provided between the fan 6a farthest from the motor and the fan 6b farthest from the motor has the highest natural frequency.

を小さく抑えることができる。FIG. 11 shows the magnitude of the vibration of the housing when the indoor units having the different natural frequencies described above are operated.
When the natural frequency is low as in the structure of FIG. 7, a resonance phenomenon occurs in the operating speed range, and the housing vibration increases. On the other hand, in the structure of this embodiment, since the natural frequency is high, the vibration of the housing can be suppressed to be small.

Also in this case, the structure in which a bearing is provided between the fan 6a and the fan 6b has the highest natural frequency. The same can be said when the number of fans becomes four. That is, when the number of fans is four, the natural frequency increases at the bearing position as shown in FIG. In addition, even in the case where the number of fans further increases, the bearing position may be determined so that the natural frequency of the shaft system is maximized.

In particular, there is an effect that electromagnetic vibration noise can be reduced. Further, according to the present invention, the natural frequency of the shaft system can be made sufficiently high, so that the vibration of the building caused by the vibration of the housing and panel of the indoor unit can be suppressed to a small level.
