First, when the power is turned on, the CPU 540 in the main controller 500 determines whether the door 310 is currently open through a door on / off signal received from the door switch 400. (S100).

At this time, if the door 310 is opened in the 100th step S100 (YES), the CPU 540 proceeds to the 100th step S100 again while the door 310 is closed. In the state (NO), the CPU 540 determines whether there is clothes to be dried in the drying chamber 200 based on the result of the drying object detecting sensor 210 (S200).

If there is clothing to be dried in the drying chamber 200 in step 200 (YES), the CPU 540 sterilizes in the sterilization chamber 100 based on the result of the sterilization object detection sensor 110. It is determined whether the clothing to be present (S300).

At this time, if there is clothes to be sterilized in the sterilization chamber 100 in the 300th step (S300) (YES), the CPU 540 controls the sterilizer drive unit 560 to ultraviolet rays in the sterilizer 120 The lamp 121 and the fans 123 and 124 are driven to sterilize the clothing existing in the sterilization chamber 100 (S400). In this case, the sterilizer 120 sterilizes clothes by using a composite material of oxygen anion (O ₂ −) and oxygen radicals, which are sterilization materials generated by chemical reaction between photocatalyst (TiO 2) and ultraviolet rays. The sterilizer 120 keeps sterilizing operation until the user opens the door 310 to take out the clothing.

Thereafter, the CPU 540 turns on the dryer 240 based on the temperature and the amount of humidity in the drying chamber 200, which are the resultant values of the temperature and humidity sensors 220 and 230, to below a set humidity and temperature threshold. The clothes in the drying chamber 200 are dried. The CPU 540 displays the drying situation to the user step by step using the first, second, third, fourth, and fifth LEDs 611, 612, 613, 614, and 615 of the display unit 600. After drying is completed, the dryer 240 is turned off (S500).

Hereinafter, a detailed operation process of the above-described 500th step S500 will be described in more detail with reference to FIG. 9.

First, the CPU 540 determines whether humidity is present in the drying chamber 200 based on the result data of the humidity sensor 230 (S501).

At this time, if there is no humidity inside the drying chamber 200 in step 501 (NO) (NO), the flow returns to step 100 (S100), while in step 501 (S501) the current drying chamber ( If there is humidity in the interior (YES), the CPU 540 turns on the dryer 240 and then determines whether the humidity value of the interior of the drying chamber 200 is less than 10% (S502).

If the humidity value of the interior of the drying chamber 200 is less than 10% (YES) in step 502 (SES), the CPU 540 turns off the heater 242 of the dryer 200 (S503).

Thereafter, the CPU 540 determines whether the temperature inside the drying chamber 200 is less than 20 ° based on the result data of the temperature sensor 220 (S504).

At this time, if the current temperature inside the drying chamber 200 is 20 ° or more (NO) in step 504, the process proceeds to step 504 again (S504), while the temperature inside the current drying chamber 200 is less than 20 °. Back (YES) The CPU 540 turns off the dryer 240 and then displays a drying completion message to the user through the display unit 600 (S505).

On the other hand, when the current humidity value of the interior of the drying chamber 200 is 10% or more (NO) in step 502 (S502), the CPU 540 notifies that the current humidity value of the interior of the drying chamber 200 is 10% or more. After the first LED 611 is turned on, it is determined whether the current humidity value of the interior of the drying chamber 200 is less than 20% (S506).

At this time, if the humidity value in the current drying chamber 200 is less than 20% (YES) in step 506 (SES), the CPU 540 turns off the first LED 611 and then the current drying chamber 200. In step S507, it is determined whether the internal temperature is 60 ° or less. Accordingly, the first LED 611 blinks when the humidity value of the interior of the drying chamber 200 is between 10% and 20%.

If the internal temperature of the drying chamber 200 is less than 60 ° in step 507 (YES), the CPU 540 turns on the heater 242 and then proceeds to step 502 (S502). If the internal temperature of the drying chamber 200 exceeds 60 ° (NO), the heater 242 is turned off and then the process proceeds to step 502 (S502). Here, the reason why the CPU 540 turns off the heater 242 when the temperature inside the drying chamber 200 exceeds 60 ° is to maintain the temperature inside the drying chamber 200 at 60 ° or less. The reason is to prevent the clothes existing in the drying chamber 200 from being damaged.

On the other hand, if the humidity value of the interior of the drying chamber 200 is 20% or more (NO) in step 506 (S506), the CPU 540 informs that the humidity value of the interior of the drying chamber 200 is 20% or more. After the second LED 612 is turned on, it is determined whether the current humidity value of the interior of the drying chamber 200 is less than 40% (S509).

At this time, when the humidity value of the interior of the current drying chamber 200 is less than 40% (YES) in step 509, the CPU 540 turns off the second LED 612 and then the current drying chamber 200. It is determined whether the internal temperature is 60 ° or less (S510). Accordingly, the second LED 612 blinks when the humidity value of the interior of the drying chamber 200 is between 20 and 40%.

If the internal temperature of the drying chamber 200 is less than 60 ° in step 510 (YES), the CPU 540 turns on the heater 242 and then proceeds to step 506 (S506). If the internal temperature of the drying chamber 200 exceeds 60 ° (NO), the heater 242 is turned off and then the process proceeds to step 506 (S506).

On the other hand, if the current humidity value of the interior of the drying chamber 200 is 40% or more (NO) in step 509 (S509), the CPU 540 notifies that the humidity value of the interior of the drying chamber 200 is 40% or more. After turning on the third LED 613, it is determined whether the current humidity value of the interior of the drying chamber 200 is less than 60% (S512).

At this time, if the humidity value of the interior of the current drying chamber 200 is less than 60% (YES) in step 512, the CPU 540 turns off the third LED 613 and then the current drying chamber 200. In step S513, it is determined whether the internal temperature is 60 ° or less.
