Technical Field

[0001] The utility model relates to the technical field of elevator air conditioners, in particular to a variable frequency controller of a variable frequency elevator air conditioner. Background Art

[0002] The inverter is mainly composed of rectification (AC to DC), filtering, inversion (DC to AC), braking unit, drive unit, detection unit and processing unit. The inverter adjusts the voltage and frequency of the output power supply by the internal IGBT switch, and provides the required power supply voltage according to the actual needs of the motor, thereby achieving the purpose of energy saving and speed regulation. In addition, the inverter has many protection functions, such as over-current, over-voltage, overload protection, etc. With the continuous improvement of industrial automation, the inverter has also been widely used;

This patent mainly adopts the design of setting a refrigerant device on the upper surface of the drive controller. The heat generated by the drive controller during use will be offset by the refrigerant device, and then the mounting plate can be cooled with the auxiliary cooling fan. The lower temperature of the mounting plate will lower the overall temperature of the outside of the reactor body, thereby achieving the advantages of effectively processing heat, improving the stability of the electric control, and effectively ensuring the effect of use. However, during use, dust will be adsorbed and accumulated on the dustproof plate, which cannot be cleaned in time and is difficult to clean.

[0031] Working principle:

[0032] Step 1: First, install the frequency conversion controller body 1 and the bearing plate 2.

When the clamping plate 505 releases the contact with the inner wall of the groove 504, the clamping plate 505 will form a clamping effect with the bottom wall of the U-shaped frame 501. When cleaning, the servo motor 6 can be started to drive the reciprocating screw 401 to rotate through the belt connection group 7. The rotation of the reciprocating screw 401 is used to move the dust plate 402, the connecting frame 404 and the rubber scraper 407, so as to perform dust removal. At this point, the entire work process is completed.
