[0003] For example, the inverter with the authorization announcement number CN111509951A, the above document can prevent some impurity particles from entering the inverter body through the air inlet slot by installing the air inlet filter assembly at the bottom of the inverter body, and at the same time, through the cooperation of the two baffles and the guide plate in the air inlet filter assembly, some impurity dust can be discharged from the air outlet, and the moisture absorption plate can adsorb the water vapor contained in the gas to prevent the gas from being mixed with water vapor, which causes the internal parts of the inverter to be corroded. However, during the use process, the inverter in the above document is usually fixed inside the ultrasonic dishwasher by the external mounting plate and bolts. Since the inverter and the mounting plate are an integrated structure, when the inverter inside the ultrasonic dishwasher is damaged, the bolts around the mounting plate for fixing the inverter need to be removed in turn to repair and replace the inverter. However, since there are many bolts used, the disassembly operation of the inverter inside the ultrasonic dishwasher is relatively cumbersome, so it is not convenient to repair the inverter inside the ultrasonic dishwasher.

[0004] Also, during the use of the inverter in the above-mentioned document, the inverter and the heat dissipation slot are an integrated structure, so the heat dissipation slot cannot be disassembled. As a result, the heat dissipation slot is easily affected by the external environment due to long-term use of the inverter, causing dust to accumulate on the heat dissipation slot, causing the heat dissipation slot to become blocked, thereby affecting the heat dissipation effect of the inverter, easily causing damage to the inverter, and affecting the operation of the ultrasonic dishwasher.
