CONTROL METHOD FOR LAUNDRY DRYER

摘要

Disclosed is a control method for a laundry dryer. The laundry dryer is a heat-pump laundry dryer, and a compressor is a variable-frequency compressor. According to the amount of laundry, a minimum running frequency of the compressor is set, and the more the laundry is, the greater the set minimum running frequency is. Specifically, when laundry drying is started, the amount of laundry is detected, and according to the detected information, a minimum running frequency, corresponding to the information, of the compressor, is invoked, and a minimum running frequency of the compressor of the current laundry drying process is set. In the improved control method for a compressor in a heat-pump laundry dryer of the present invention, when there is a large amount of laundry, a set minimum running frequency of the compressor is increased, so as to increase the drying temperature inside the cylinder, shorten the drying duration, and eventually achieve a more desirable laundry drying effect; when there is a small amount of laundry, because the laundry is relatively loose, the moisture inside the laundry can easily evaporate, and through comprehensive comparison of the power consumption and drying efficiency of the compressor, a low minimum running frequency of the compressor can be set, thereby lowering energy consumption in comparison.
