No. 926, Japanese Patent Application No. 60-20862, etc.

[Problem that the invention seeks to solve]

In such a cleaning device, when the cleaning liquid jetted from the jet nozzle collides with the object to be cleaned, it floats in the form of a mist, flows out from the upper opening of the outer envelope, and surrounds the cleaning device. There was a problem of contamination.

[Means for solving problems]

The present invention has been made to solve this problem, and includes a support base (6) on which the object to be cleaned (4) is placed inside an envelope (1) having an opening (50) on the top surface. A jet nozzle (13) that sprays liquid onto the top surface of the object to be cleaned (4)
In the cleaning device, the opening (50) of the outer envelope (1) is formed by a cylindrical portion (1a), and the cylindrical portion (1a)

1b) to suck air through the suction device (30);
The cleaning device is characterized by being provided with a suction port (20) connected to the cleaning device.

[Effect]

In such a cleaning device, a cleaning liquid is jetted from a jet nozzle (13) onto an object to be cleaned (4), and dust on the surface of the object to be cleaned is blown off and removed by the jetting force. In this case, the cleaning liquid sprayed onto the object to be cleaned (4) becomes a mist and floats when it collides with the object to be cleaned (4), etc. This mist rides on the air sucked in from the opening (50) and travels through the cylindrical part (
It is sucked into the suction port (20) through the gap (1b) between the lower end of 1a) and the object to be cleaned (4).

That is, since the opening (50) is formed in the cylindrical part (1a), the airflow occurs from the upper side to the lower part in the cylindrical part (1a), and the mist flows to the outside of the outer envelope (1). In addition to preventing the outflow, an opening (50) is formed in the cylindrical part (1a) to narrow the gap (1b) between the lower end of the cylindrical part (1a) and the object to be cleaned (4). Therefore, the air sucked from the opening (50) narrows this gap (1b), so that the air sucked from the opening (50) is sucked almost uniformly from the entire circumference of this gap (1b). The mist fills the gap (
1b) can be led to the suction port (20) from the entire circumference.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

A cylindrical envelope 1 is provided around the support base 6. Furthermore, an ultrasonic transducer 7a is mounted on the bottom inclined surface of the outer enclosure 1.
7b and 7c are attached.

A liquid injection nozzle 2 for filling the liquid 3 for transmitting ultrasonic energy into the outer envelope 1, a brush 10 having a brush arm 10a for discharging the liquid 3 and cleaning the brush scrubber, and a brush scrubber. A rinse nozzle 11 that supplies liquid 11a necessary for cleaning and rinsing, and a jet nozzle 13 for performing high-pressure jet cleaning.
A gas injection nozzle 12 and the like, which enhances the drying effect when the support base 6 is rotated at high speed and liquid remaining on the tray 5 and the object to be cleaned 4 is removed by centrifugal force, is installed in the upper part of the outer envelope 1. Alternatively, it can be installed near the support stand 6 and moved to the top of the support stand 6 for cleaning when necessary.

It is designed to dry.

For example, the object to be cleaned 4 has a smooth surface that has been finely processed, and the tray 5 on which the object to be cleaned 4 is placed and fixed may be adapted to the shape of the object to be cleaned 4 as appropriate. The matching receiver is machined so that the object to be cleaned 4 can be fixed thereon, and the back side of the tray 5 has a vacuum path so that the tray 5 and the object to be cleaned 4 can be fixed to a support stand 6 using vacuum. Groove 5
A is provided.

Further, the support base 6 has a vacuum suction hole 6a in the center thereof, and is further sealed and fitted with the rotation shaft 9 and the vacuum shaft 9a in a liquid-tight manner.

The above-mentioned outer enclosure 1 is fixed to the vertical drive shaft 8,
Depending on the type of cleaning, it is formed to move up and down while being sealed liquid-tightly with the rotating shaft 9.

Furthermore, outside the cylindrical portion 1a, and this cylindrical portion 1a
A suction port (20) is provided above the lower end of. This suction port 20a is communicated with the suction device 3° via a communication pipe 20a. Suction device! ! 30 has fan 3
0a and a filter 31, the cleaning liquid contained in the air sucked by the fan 30a is collected by the filter 31, drips from the filter 31, and is stored as a stored liquid 32.

Note that 2a and 13a represent cleaning liquids, and 14 is a liquid outlet.

Next, the operation of the device having the above configuration will be explained.

First, in ultrasonic cleaning, the envelope 1 is moved upward, the discharge valve connected to the liquid discharge port 14 is closed,
The cleaning liquid 2a is discharged from the liquid injection nozzle 2 so as to fill the cleaning liquid 2a above the object 4 to be cleaned. On this occasion.

The object to be cleaned 4 is fixed in advance by vacuum suction.

Furthermore, the ultrasonic transducers 7a, 7b, and 7c are activated, and the liquid 3
The object 4 to be cleaned is cleaned using ultrasonic energy.

Here, rotating the support base 6 or moving the envelope 1 up and down so that the ultrasonic energy is evenly transmitted to the object 4 to be cleaned does not impede the cleaning efficiency in the slightest.

After performing ultrasonic cleaning as described above, the discharge valve connected to the liquid discharge port 14 is opened, the liquid 3 is discharged, and the envelope 1 is moved downward.

Then, the object to be cleaned 4 is still fixed to the support stand 6 together with the tray 5 by vacuum, and the brush 10 installed on the top of the outer enclosure 1 or near the support stand 6 is moved by the brush arm 10a. Place it tightly on object 4.

At this time, by rotating the support base 6, the object to be cleaned 4 comes into full contact with the brush 1o, and the object to be cleaned 4
It is mainly used to clean the smooth surface of the machine.

The cleaning liquid 11a is discharged onto the object to be cleaned 4 from the rinse nozzle 11 simultaneously with the rotation of the brush 10 or at appropriately short intervals.

Next, remove the brush 10 from above the object 4 to be cleaned, and remove the liquid 1.
Stop dispensing 1.

Further, a jet nozzle 13 for high-pressure jetting is positioned above the object to be cleaned 4, and while the support base 6 is kept rotating, the cleaning liquid 13a is jetted at high pressure to clean the object to be cleaned 4. In this case, the number of rotations of the support base 6 is not limited, and the cleaning effect can be improved by repeatedly moving the jet nozzle 13 onto the tray 5 over the entire surface or half a time at the top of the device. be.

After high-pressure jet cleaning, in some cases, rinse nozzle 1
The final rinse is performed while discharging the rinsing liquid 11a from the rinsing liquid 11a.

Next, the rinsing liquid 11a is stopped, the support stand 6 is rotated at high speed, and the liquid remaining on the object to be cleaned 4 and the tray 5 is removed by centrifugal force, and drying is performed.

At this time, in order to increase the drying efficiency, it is effective to further increase the number of rotations or to spray dry gas from the gas injection nozzle 12 onto the object to be cleaned 4 and the tray 5.

After the drying is completed, the rotation of the support base 6 is stopped, and furthermore, the vacuum suction is stopped, and the series of cleaning by the cleaning device is completed.

Now, the point in which the cleaning liquid 13a is jetted at high pressure by the jet nozzle 13 for high-pressure jets to clean the object 4 to be cleaned will be explained in more detail. When the cleaning liquid injected from the jet nozzle 13 collides with the object to be cleaned 4 and the tray 5, it floats in the form of mist, but the mist is transferred to the outside of the envelope 1 by the air sucked through the opening 50. without spilling.

Riding this suction air flow, the lower end of the cylindrical portion 1a and the tray 5
It is sucked into the suction port 20 through the gap 1b. To explain this point in more detail, since the opening 50 is formed in the cylindrical portion 1a, it is possible to generate an air flow from above to below over the height of the cylindrical portion 1a. This air flow can effectively prevent the mist from flowing out of the envelope 1. In addition, since the opening 50 is formed in the cylindrical part 1a and the gap 1b between the lower end of the cylindrical part 1a and the object to be cleaned 4 side (the outer peripheral edge of the tray 5) is narrowed, the suction from the opening 50 is Air is sucked almost uniformly from the entire circumference of the gap 1b, and the mist is sucked from the entire circumference of the gap to the suction port 2.
It can lead to 0.

Therefore, it is possible to prevent the mist from flowing out of the envelope 1 over the entire circumference.

Furthermore, the cylindrical part 1a is formed to hang down from the upper surface of the outer envelope 1, and the suction port 20 is provided outside the cylindrical part 1a and above the lower end of the cylindrical part 1a, so that liquid during ultrasonic cleaning can be removed. 3 from flowing into the suction port 20, and
Suction air can be guided through the gap between the cylindrical portion 1a and the outer envelope 1.

〔Effect of the invention〕

According to the present invention, a cleaning device having the following effects can be provided.

■ Occurs when the cylindrical part (1a) of the envelope (1) generates an air flow from above to below and the cleaning liquid is sprayed onto the object to be cleaned (4) from the jet nozzle (13). Since the mist can be carried by this air flow and reliably sucked into the suction port (20), it is possible to prevent this mist from flowing out to the outside of the envelope (1).

■The lower end of the cylindrical part (1a) of the outer envelope (1) and the object to be cleaned (
4) Narrow the gap (1b) with the side.

This is because the air sucked through the opening (50) is sucked almost uniformly from the entire circumference of this gap (1b).

The vibrations can be guided from the entire circumference of the gap (1b) to the suction port (20), and the mist can be reliably prevented from flowing out of the envelope (1) from this point as well.
