Then, the control method of the sterilization drying apparatus according to an embodiment of the present invention using the sterilization drying apparatus having the above configuration will be described with reference to FIG.

First, if the CPU 704 in the main controller 700 is turned on and the door 210 is closed, whether the contents to be dried and sterilized are present in the drying / sterilization chamber 100. Determine (S100). Here, the 100th step (S100) is a phase The drying / sterilization object monitoring sensor 1300 may be detected by a sensing operation. In addition, the contents to be dried and sterilized are underwear, baby clothing, towels and the like.

At this time, if there is no content to be dried and sterilized in the drying / sterilization chamber 100 in step 100 (NO) (NO), the CPU 704 proceeds to step 100 (S100) again, If there are contents to be dried and sterilized as shown in FIG. 8 (YES), it is determined whether the user selects the cloth material and the wind strength mode simultaneously or only the sterilization mode through the button operation unit 400. (S200). Here, a method of selecting a cloth material, a wind strength, or a sterilization mode through the button manipulation unit 400 will be omitted since it has been already mentioned.

When the user selects the cloth material and the wind strength mode through the button manipulation unit 400 in the 200th step (S200), the CPU 704 is based on the temperature and humidity in the drying / sterilization room 100. The dryer 500 is heated to below a temperature threshold that depends on the material of the cloth, and the contents of the drying are displayed to the user step by step while drying the contents. When the drying is completed, the dryer 500 is stopped (S300).

Hereinafter, a detailed operation process of the above-described 300th step S300 will be described in detail with reference to FIG. 12.

First, when any fabric material is selected from cotton, blend, or seal through the button manipulation unit 400, the CPU 704 sets a predetermined temperature threshold corresponding to the fabric material (S301). At this time, the temperature threshold value according to the above-described cloth material is an example. For example, 65 ° for cotton, 50 ° for blend, 40 ° for seal, which can be changed according to the experimental results.

Then, the CPU 704 determines whether the wind strength mode of the button operation unit 400 is selected as the normal mode or the rapid mode (S302).

At this time, when the wind intensity mode is selected as the normal mode in step 302 (S302), the CPU 704 may set the revolutions per minute (RPM) of the fan 501 in the dryer 500 in a normal manner. After setting to the set value of the mode to turn on the dryer 500 (S303). Here, the RPM of the fan 501 corresponding to the normal mode is determined at the optimum speed by experiment.

Subsequently, the CPU 704 determines whether the humidity value of the interior of the drying / sterilization chamber 100 is less than 10% (S304).

If the humidity value in the current drying / sterilization chamber 100 is less than 10% (YES) in step 304, the CPU 704 turns off the heater 502 of the dryer 500 (S305). ).

Thereafter, the CPU 704 determines whether the current temperature of the drying / sterilization chamber 100 is lower than a preset room temperature (S306). Here, the above-mentioned preset room temperature means a temperature that is not hot when the user opens the door 210 of the apparatus and takes out the contents, and it is preferable to set the temperature to about 20 °.

At this time, if the current temperature inside the drying / sterilization chamber 100 is greater than or equal to a predetermined room temperature (NO) in step 306 (S306), the CPU 704 proceeds to step 306 again (S306). Room temperature temperature preset internal drying / sterilization chamber 100 If less than (YES) the fan 501 of the dryer 500 is turned off (OFF) to complete the drying mode (S307).

On the other hand, if the humidity value in the current drying / sterilization chamber 100 is 10% or more in step 304 (NO) (NO), the CPU 704 is the amount of humidity in the current drying / sterilization chamber 100 is dried After recognizing that it is included in the range, while the heater 502 of the dryer 500 is turned on to dry while the current amount of humidity in the drying / sterilization chamber 100 the first to 5 LED (801, 802, 803) Steps are displayed to the user through the on / off (ON / OFF) of, 804, 805 (S308). At this time, the above-mentioned drying range means a humidity range of 10 to 90%, the amount of humidity through the ON / OFF (ON / OFF) of the first to fifth LED (801, 802, 803, 804, 805). The display can be changed according to the display algorithm.

Thereafter, the CPU 704 determines whether the current temperature of the drying / sterilization chamber 100 is lower than or equal to a predetermined temperature threshold to match a cloth material such as cotton, blend, or seal (S309).

At this time, if the current temperature inside the drying / sterilization chamber 100 is lower than or equal to the temperature threshold (YES) in step 309 (SES), the CPU 704 turns on the heater 502 and then in step 304 (S304). On the other hand, if the current temperature inside the drying / sterilization chamber 100 exceeds the temperature threshold (NO), the heater 502 is turned off and then proceeds to the 304th step (S304) (S310).

In addition, when the wind intensity mode is selected as the high speed mode in the step 302 (S302), the CPU 704 sets the RPM of the fan 501 in the dryer 500 to a set value of the high speed mode to allow the dryer ( After the 500 is turned on, the process proceeds to the 304 th step S304 (S311). Here, the rapid mode is a mode that allows the contents to be dried in a faster time by controlling to rotate faster than the normal mode, the RPM of the fan 501 corresponding to the rapid mode is determined at the optimum speed by the experiment.

After the 300th step S300, the CPU 704 generates ozone (O ₃ ) through the sterilizer 600 to the drying / sterilization chamber 100 to sterilize the contents for a predetermined time and then the sterilizer. The 600 is turned off (S400). At this time, the set sterilization time is about 10 minutes, which can be changed as much as the initial setting value.

In addition, when the user selects the sterilization button 440 through the button manipulation unit 400 in the 200th step (S200), the CPU 704 may dry the ozone (O ₃ ) through the sterilizer 600. After the sterilization chamber 100 is generated to sterilize only the contents for a set time, the sterilizer 600 is turned off and ends (S500).

On the other hand, during the operation of the above-described step 100 (S100) to 500 (S500), the user selects the cancel button 430 through the button operation unit 400, or the current drying When the overheat temperature is detected by the overheat temperature sensor 504 due to a failure of the fan 501 of the machine 500, the CPU 704 automatically shuts off the power to forcibly terminate the current drying or sterilization mode. Let's do it.

In addition, when the CPU 704 receives an air purification selection signal from the air purification button 460 of the button operation unit 400, the CPU 704 controls the sterilizer 600 to perform an air purification function for a predetermined time.

Although the present invention has been described in more detail with reference to some embodiments, the present invention is not necessarily limited to these embodiments, and various modifications can be made without departing from the spirit of the present invention.
