[0004]

In the cleaning device 50, the vibration output from the vibration mechanism 60 can be directly applied to the object to be cleaned. However, since the amplitude of the vibration is small, the cleaning takes a long time. Was inefficient. Also, when the object to be cleaned is drained after washing, the object to be cleaned is vibrated by the vibration mechanism 60. However, since the amplitude of the vibration is small, a sufficient draining effect can be obtained. Did not. Therefore, in order to apply a large-amplitude vibration (vibration displacement amount) to the object to be cleaned, it is also possible to employ a vibration unit that generates a large-amplitude vibration or a special vibration unit configured to be able to change the frequency of the vibration. As conceived, since the vibration means having such a function is generally large, there has been a problem that the vibration mechanism becomes unnecessarily large. Such a large-sized vibration mechanism is not suitable for a cleaning apparatus that operates continuously from cleaning to drying, and thus the above-described measures are not preferable. The present invention has been made in view of the above circumstances, and since a sufficient amount of vibration displacement can be obtained with a simple configuration, a cleaning effect and a draining effect can be obtained, and further, continuously from cleaning to drying. An object of the present invention is to provide a vibration mechanism of a cleaning device suitable for a cleaning device that operates.

[0006]

According to the vibration mechanism of the cleaning apparatus of the present invention, the first to fifth
Due to the interaction of the anti-vibration spring, the amplitude of the vibration transmitted to the object to be cleaned can be greatly increased as compared with the amplitude of the vibration output from the vibration means. Therefore,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a vibration mechanism of a cleaning apparatus according to the present invention will be described below in detail with reference to the accompanying drawings. The vibration mechanism 1 according to the present embodiment includes a holding frame 2 for temporarily holding the object to be cleaned A, a vibrating means 3 disposed on the holding frame to directly vibrate the object to be cleaned A, and a holding frame 2 from above. The apparatus includes a support frame 4 for supporting the cylinder, and a cylinder (moving means) 5 for vertically moving the support frame. Further, an intermediate plate (intermediate frame) 6 is disposed between the holding frame 2 and the support frame 4, and a pair of first guide members 7, 7 are disposed between the holding frame 2 and the intermediate frame 6. In addition, a pair of second guide members 8 is provided between the intermediate frame 6 and the support frame 4.

The first guide member 7 is penetrated by the upper member 2a of the holding frame 2 and the intermediate plate 6, and slidably connects each of them. The second guide member 8 is penetrated by the intermediate plate 6 and the lower member 4a of the support frame 4, and slidably connects each other. Between the lower end 7a of the first guide member 7 and the upper member 2a of the holding frame 2, a first
The anti-vibration spring 9 is interposed. A second anti-vibration spring 10 is interposed between the upper end 7 b of the first guide member 7 and the intermediate plate 6. A third vibration-proof spring 11 is interposed between the lower end 8 a of the second guide member 8 and the intermediate plate 6, and the upper end 8 of the second guide member 8 is provided.
A fourth anti-vibration spring 12 is interposed between b and the lower member 4a of the support frame 4. Further, the intermediate plate 6 and the lower member 4a of the support frame 4 are connected to each other at a substantially intermediate position by using a fifth anti-vibration spring 13. As shown in the drawing, the fifth anti-vibration spring 13 is installed horizontally to prevent the intermediate plate 6 from vibrating in the vertical direction with respect to the support frame 4 and to prevent the intermediate plate 6 from moving in the horizontal direction with respect to the support frame 4. It works to prevent vibrations.

As the vibration means 3, for example, a vibration generator such as a vibration motor, an electromagnetic vibrator, or a pneumatic vibrator motor can be employed. Anything can be adopted. Further, when the vibration generator is a vibration motor or a pneumatic vibrator motor, using a pair of these, arranged so that the rotation axes are orthogonal to each other,
The vibrating means 3 may be configured so that the vibrating surfaces are orthogonal to each other and vibrations in all directions (composite vibration) are applied to the object A to be cleaned. Similarly, when the vibration generator is an electromagnetic vibrator,
By using a pair of them, the vibration means 3 may be arranged so that the vibration directions are orthogonal to each other, and the vibration means 3 may be configured to apply omnidirectional vibration (composite vibration) to the object A to be cleaned. The object to be cleaned A is
It is temporarily fixed to the lower part of the holding frame 2 by the holding plate 14. The object to be cleaned A may be set in a plurality of blocks as shown in FIG. 1 and set on the holding frame 2, or may be stored in a basket as shown in FIG. May be.

Next, the operation of the vibration mechanism 1 of the present embodiment will be described. In the vibration mechanism 1 of the present embodiment,
Vibration from the vibration means 3 which is a vibration source is transmitted to the object to be cleaned A via the holding frame 2, while transmission to the support frame 4 side is regulated by the synergistic action of the vibration-proof springs 9 to 15. . The state of transmission of this vibration is shown in FIGS. In the figure, the horizontal axis is the time axis (50
msec / 1 scale), and the vertical axis represents amplitude (100 mV / 1).
Scale). FIGS. 2 to 4 show how the vibration mechanism 1 vibrates at various points when the vibration mechanism 1 is operated in the air. FIG. 2 shows a state of vibration at a place where the vibration means 3 as a vibration source is arranged. FIG. 3 shows a state of vibration at a portion of the holding plate 14 for fixing the object to be cleaned A to the holding frame 7. FIG. 4 shows a state of vibration at a lower portion of the support frame 8. As is clear from FIGS. 2 and 3, in the vibration mechanism 1 of the cleaning device of the present embodiment,
It can be seen that the amplitude of the vibration output from the vibration means 3 is greatly amplified by the synergistic action of the first to fifth vibration isolating springs 9 to 13 and transmitted to the object A to be cleaned. 2 and 3
According to the above, the amplification factor of the vibration in the air reaches almost 6 times. As is clear from FIGS. 2 and 4,
It can be seen that the amplitude of the vibration transmitted from the vibration means 3 to the support frame 4 side is sufficiently small due to the synergistic action of the first to fifth vibration-proof springs 9 to 13. Therefore, a sufficient draining effect of the cleaning target A in the air can be obtained without using a large-sized vibrating means 3.

FIGS. 5 to 7 show how the vibration mechanism 1 vibrates at various points when the vibration mechanism 1 is operated underwater. FIG. 5 shows a state of vibration at a place where the vibration means 3 as a vibration source is arranged. FIG. 6 shows a state of vibration at a portion of the holding plate 14 that fixes the object A to be held to the holding frame 7. FIG. 7 shows a state of vibration at a lower portion of the support frame 8. As is clear from FIGS. 5 and 6, in the vibration mechanism 1 of the cleaning apparatus of the present embodiment, the amplitude of the vibration output from the vibration means 3 is increased by the synergistic action of the first to fifth vibration-proof springs 9 to 13. It can be seen that the signal is greatly amplified and transmitted to the cleaning object A. According to FIGS. 5 and 6, the amplification factor of the vibration in the water is approximately three times. This is smaller than in air due to the effect of the viscous drag of water. As is clear from FIGS. 5 and 7, the amplitude of the vibration transmitted from the vibration means 3 to the support frame 4 side is sufficiently reduced due to the synergistic action of the first to fifth vibration isolation springs 9 to 13. I understand. Therefore, a sufficient cleaning effect of the cleaning target A in the cleaning liquid can be obtained without using a large-sized vibrating means 3.

That is, in the present invention, the amplitude of the vibration output from the vibrating means is increased by the synergistic action of the first to fifth anti-vibration springs without changing the amplitude or the frequency of the vibration. The amplitude of the vibration transmitted to the cleaning object can be greatly increased. Therefore, in the present invention,
It is not necessary to employ a special vibration means configured to generate a vibration having a large amplitude or to change the frequency thereof, and the vibration mechanism can be made compact.
Therefore, the vibration mechanism of the present invention can obtain a sufficient amount of vibration displacement within a preset frequency, so that a sufficient cleaning effect and drainage effect can be obtained. As a result, a conventional compact device can be used as the vibration means as it is, and it is most suitable for a cleaning apparatus that operates continuously from cleaning to drying. Further, since the vibration mechanism of the cleaning device of the present invention has a simple configuration, it is easy to implement and has great economic merit.
