Problems solved by technology
[0030] Since cold water is periodically supplied to a conventional washer-dryer and discharged to the outside regardless of the load and the temperature of the cold water, the consumption rate of cold water and the consumption rate of electricity are increased
In addition, drying of clothes using cool air is performed at a specified time, and when the load of clothes is small, the total drying time is prolonged, and when the load of clothes is large, the clothes cannot be cooled sufficiently, thereby causing the user to be harassed. scald
[0031] Also, since in the drying operation, cold water is supplied to the conventional laundry dryer at specified intervals and discharged to the outside, the temperature of the peripheral air and the temperature of the cold water cannot be compensated

The present invention provides a drying control device and method of a laundry dryer, in which cold water falling from a condensation pipe to a tub promotes condensation of moisture contained in circulating air, thereby improving condensation capability; cooling is set differently according to loads. Air drying time, so that the drying time is shortened when the load is small; and the clothes can be dried quickly according to the needs of the user, the power consumption rate is minimized, or the cold water consumption rate is minimized; and the temperature of the air and the temperature of the cold water are used The difference between them controls the drying operation so that the drying operation can be effectively performed according to the load state to improve the drying capacity.
Description
Technical field [0001] The present invention relates to a dryer or a washing and drying machine, and in particular to a drying control device and method for a washing and drying machine, which can appropriately perform drying operations according to operating conditions. Background technique [0002] General washing machines can be divided into washing machines with only washing functions, dryers with only drying functions, and washing and drying machines with washing and drying functions. [0003] figure 1 It is a longitudinal sectional view showing the internal structure of a conventional washing and drying machine. [0004] Such as figure 1 As shown, the conventional washing and drying machine includes: a tub 10 installed in the cabinet 2 and supported by a spring 2 and a shock absorber 6; a drum 20 installed in the tub 10 to contain clothes; a door 22 connected to The cabinet 2 is used to open and close the front surface of the drum 20; a heating pipe 30 is installed on th...
