[0002]

2. Description of the Related Art As is well known, conventional ultrasonic cleaning machines
For example, as shown in FIG. 6, a horn 63, which is suspended and supported above a cleaning tank 62 in which a cleaning liquid 61 is spread, has its supporting end connected to an output end of an ultrasonic transducer (not shown) via a cone 64. , Part of the tip of this horn 63 is the cleaning liquid 6
It is soaked in 1 and the object to be cleaned 65 placed thereunder is irradiated with ultrasonic vibration to be cleaned.

[0003]

However, in the above-mentioned conventional washing machine, when the cleaning liquid becomes dirty, the dirt reattaches to the object to be cleaned. Moreover, if an attempt is made for side irradiation other than top irradiation, the structure becomes complicated. That is, it is impossible to irradiate the object to be cleaned from any direction and clean it. Further, since the object to be cleaned is put in the cleaning tank, there are various problems such that the installed object such as a toilet cannot be cleaned and the side wall of the structure cannot be cleaned.

The present invention has been made in view of the above conventional problems, and an object thereof is to provide a portable ultrasonic cleaning machine which does not require a cleaning tank and can irradiate and clean an arbitrary object to be cleaned from an arbitrary direction. To do.

[0005]

In order to achieve the above-mentioned object, the ultrasonic cleaning machine of the present invention has the following constitution. That is, the ultrasonic cleaning machine according to the first aspect of the invention includes an oscillator that generates an ultrasonic frequency electric signal; an ultrasonic vibrator to which the ultrasonic frequency electric signal is applied, and one end of the ultrasonic vibrator. A portable box body that supports on its side wall a horn that is directly connected to the output end or via a cone and has the other end protruding to the outside; and the horn is a mechanism for letting out liquid from the tip surface of the other end. Is provided;

The ultrasonic cleaning machine according to the second aspect of the invention includes an oscillator for generating an ultrasonic frequency electric signal; an ultrasonic vibrator to which the ultrasonic frequency electric signal is applied, and one end of which is the ultrasonic wave. A portable box body that supports a horn, which is connected to the output end of the vibrator directly or through a cone and has the other end protruding to the outside, on the side wall; and a tip surface of the other end of the horn that emits ultrasonic waves. And a means for spraying a liquid onto the washed material.

[0007]

Next, the operation of the ultrasonic cleaning machine of the present invention constructed as above will be described. In the present invention, a mechanism is provided in which the horn is projected from the side wall of the portable box body and the liquid is caused to flow out from the tip end surface of the projected other end of the horn (first invention), or separately on the article to be cleaned. On the other hand, a means for spraying a liquid is provided (second invention) so that the surface of the object to be cleaned which has been peeled off by irradiation with ultrasonic waves can be washed away.

Therefore, even if the object to be cleaned is a part of an installed object such as a toilet bowl or a structure, the object can be cleaned by irradiating ultrasonic waves to the target site from an arbitrary angle with the tip end surface of the horn. . Further, since the cleaning liquid flows away without staying, dirt does not reattach to the object to be cleaned.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an ultrasonic cleaning machine according to an embodiment of the present invention. This device basically comprises an oscillator 1 and a portable box 2.

The box 2 has, for example, a rectangular parallelepiped shape, and has a vibrator 21 and a fan 25 for cooling the excitation end of the vibrator 21 arranged therein. One end of the horn 23 is connected to the output end of the vibrator 21 via a cone 22, but the cone 22 is fixed to the side wall of the box body 2 and the other end of the horn 23 is projected to the outside of the box body 2. is there.

The vibrator 21 is, for example, a bolted Langevin type ultrasonic vibrator used in a conventional washing machine, and receives an ultrasonic frequency electric signal from the oscillator 1 to generate ultrasonic vibration as in the conventional case. . This vibration is transmitted to the horn 23 via the cone 22 and radiated from the other end tip surface, but the cone 22 may be omitted. In this case, the horn 23 is fixed to the side wall of the box body 2 in the middle thereof.

A hose 24 which is inserted from the outside and passes therethrough is supported by the box body 2. One end of the hose 24 facing outside the drawing is connected to, for example, a faucet of the water supply, and the other end thereof protrudes from the side wall of the box body 2 to the outside as shown in the drawing.
3 is connected to the side end surface of the other end.

That is, the other end of the horn 23 is, for example, in the form of a flat plate as shown in FIG. 2, and has vertical holes (four holes in the illustrated example) 26 having openings at the tip end surface thereof and these vertical holes. A lateral hole 27 is provided which communicates the base ends of 26 with each other and has an opening on the end face on the side. The joint 2 is provided in the opening of the lateral hole 27.
The other end of the hose 24 is connected via 8. in short,
Tap water flows out from the other end of the horn 23 as a cleaning liquid.

The tip surface of the other end of the horn 23 may be a vertical flat surface as shown in FIG. 2, but may be stepped as shown in FIG. 3 (a), or as shown in FIG. 3 (b). It may be an inclined surface.

For example, as shown in FIG. 4, when the object to be cleaned 41 is a part of the side wall of the building, ultrasonic waves are emitted while the tip surface of the horn 23 is directed toward the side wall surface of the object to be cleaned 41. Is sprayed, a liquid pool 42 is formed between the tip surface of the horn 23 and the side wall surface. However, if the shape of the tip surface of the horn 23 is as shown in FIGS. Therefore, it is possible to more effectively wash away the dirt on the surface of the object to be cleaned which is peeled off by the ultrasonic vibration. Since fresh water is constantly supplied to the liquid pool, the wash water flows away as waste liquid, and dirt does not stay and adhere.

According to experiments, a frequency of 20 KHz and an amplitude of 1
0 μmp-p, distance 1 between tip surface of horn 23 and side wall surface 1
When the thickness was set to mm, a good liquid pool was formed and could be maintained for several seconds depending on the water supply amount, which contributed to cleaning. However, it should be noted that the atomization will occur when the amplitude is 10 μmp-p or more.

In the above description, the liquid was made to flow out from the horn 23 itself, but as shown in FIG. 5, for example, a nozzle 51 is separately provided and the liquid is sprayed from the nozzle 51 onto the object to be cleaned. You can

As described above, according to the ultrasonic cleaning machine of the present invention, the cleaning tank is unnecessary, the horn is projected from the side wall of the portable box body, and the liquid flows out from the tip surface of the horn. Or a means for spraying the liquid onto the object to be cleaned (second invention),
Since the surface of the object to be cleaned that has been peeled off by irradiating ultrasonic waves can be washed away, even if the object to be cleaned is a part of the installation such as a toilet bowl or part of the structure, the target site can be angled at any angle without any problem. The ultrasonic wave can be applied to the tip of the horn to clean the area by irradiating ultrasonic waves, and the cleaning liquid flows away without staying, so that dirt is not redeposited on the object to be cleaned.
