Next, the operation of the washing machine of the present invention will be described. The lid 2 is opened, an object to be washed such as a semiconductor part having dust attached to it is placed between the partition walls in the rotating basket 4, covered with the cover 5, and then attached to the motor 3.

After that, when the motor 3 is driven, the rotating basket 4 rotates with the object to be washed placed. However, the rotation speed of the motor is about 30 rpm. At the same time, by operating the solenoid valve 12 to open it, the compressed air from the compressed air source 11 is injected into the air injection nozzles 15 and 16 through the pipes 9, 7, 6 and 13, and is also injected through the pipe 14. The compressed air is supplied to the nozzles 17 and 18, respectively, and compressed air is jetted from the respective air jet nozzles toward the rotary basket 4 from above and below.

Due to this jet of air, the dust attached to the material to be washed in the rotating basket 4 is blown away. At this time, the air gun 19 may be used.

In this manner, the dust-containing air floats in the first case 1, but the blower 35 is operated to guide the dust-containing air from the opening 37 to the air introduction port 36 and further through the opening 38. After passing through the filter 39, air is passed through this filter.

The passed air passes through a sound deadening part (not shown) and is discharged into the discharge hole 4.

However, since the first case 1 is provided with the air introduction holes 28 to 33, the air can flow in and out through the route without any trouble by the operation of the blower 35.

When it is desired to operate the air gun 19 or to adjust the rotary cage, the hands can be inserted into the work holes 26 and 27 and these works can be performed through gloves.

When the amount of the material to be washed is small, the material to be washed may be placed in the basket 22, the solenoid valve 24 may be opened, and the side injection nozzle 21 or the air gun 19 may be used to inject compressed air. The object to be washed that has been washed can be taken out by drawing the basket 22 into the receiving unit 25.

The dust collected in the filter 39 is dropped into the dust case 40 by operating the dedusting lever 41, and the dust in the dust case is discharged to an appropriate place after the dust case is pulled out of the washing machine.

In this way, after all the functions of the objects to be washed have been washed, the rotating basket 4 with the lid 2 opened is taken out of the washing machine and transferred from the rotating basket to a predetermined container or the like.

An object to be washed is placed again on the emptied rotating basket, the cover is attached and the motor 3 is attached, and the lid 2 is closed to start the above-described operation.
