Benefits of technology

[0007]An object of the present invention is to provide a control method of a dryer which can activate a compressor in initial activation stably. In other words, the object of the present invention is to provide the control method which can prevent liquid refrigerant from flowing into the compressor in the initial activation of the compressor. By extension, the object of the present invention is to provide the control method which can control the quantity of the refrigerant based on temperature information relating to the compressor, to prevent overheat of the compressor.
[0008]Furthermore, another object of the present invention is to provide a control method which can reduce noise and vibration of a dryer. For that, the control method according to the present invention may adjust an activation velocity of a variable velocity type compressor, to reduce the noise and vibration generated in the compressor.

Problems solved by technology

A variety of dryers have been developed and the dryers accompany a variety of problems.
