The workpieces to be cleaned are placed in the washing basket, and then the washing basket is slid into the cleaning chamber. After the box door is closed, clean water is injected into the cleaning chamber. After half of the water is filled, the ultrasonic generator in the cleaning chamber is started to clean the workpieces in the washing basket.

[0003] The patent application of Jianjingsuo in the authorization publication number: CN116060368A discloses an ultrasonic cleaning and drying equipment and a method of using the same, comprising a machine body and an ultrasonic cleaning tank and a drying tank provided on the top of the machine body, a hanging basket is placed in the ultrasonic cleaning tank, and two L-shaped handles are symmetrically fixed on the top of the hanging basket, a first cover plate and a second cover plate are rotatably connected to the top surface of the machine body, a rectangular groove is provided on the surface of the first cover plate, a guide rod is rotatably installed on the inner bottom end of the rectangular groove, and two suspension assemblies are installed on the guide rod; through the provided suspension assembly, after the operator lifts the hanging basket containing the workpiece out of the ultrasonic cleaning tank, the hanging basket can be hung and drained through the hanging assembly, so that the cleaning liquid remaining on the surface of the workpiece and the hanging basket will fall back into the ultrasonic cleaning tank, avoiding the inconvenience caused by directly putting the hanging basket into the drying tank and causing a large amount of cleaning liquid to drip into the drying tank, and after the hanging and draining is completed, the hanging basket and the workpiece are put into the drying tank for drying.

[0004] Although the above scheme can suspend the hanging basket for drainage through the hanging component, so that the cleaning liquid remaining on the workpiece and the surface of the hanging basket will fall back into the ultrasonic cleaning tank, realizing the hanging drainage of the cleaned workpiece, but because the workpieces are in a piled state in the hanging basket, the cleaning effect of the workpieces inside the pile is not good. For this reason, we propose an ultrasonic cleaning and drying equipment and its use method. Summary of the invention

[0005] The main purpose of the present invention is to provide an ultrasonic cleaning device and a method of using the same, which can effectively solve the problem in the background technology that the workpieces are in a piled state in the hanging basket, so the cleaning effect of the workpieces inside the pile is poor.
