In general, at home, when drying laundry that washes clothes, towels, cloths, etc., it is dried by solar heat using an outdoor drying rack or by hanging in an indoor living room or room. In addition, as a sterilization method, the laundry was boiled at a high temperature before washing, or a method of sterilizing was added by adding a laundry detergent which sterilizes during washing.

However, the above-described conventional drying method has a problem in that it takes a long time to dry in a cloudy or high humidity due to the sensitive response to natural weather changes, and the conventional laundry sterilization method described above must boil laundry at a high temperature one by one. Not only is it cumbersome, it can also cause burns and damage to laundry due to high temperatures during the boiling process. In addition, when the laundry is not completely rinsed, various chemicals such as fluorescent brighteners included in the synthetic detergent may remain in the laundry, but it was difficult to visually recognize whether the detergent component remains.

In particular, fluorescent brighteners are dermatitis-inducing substances and carcinogenic controversial chemicals, but even if these ingredients remain in the laundry, they are not aware of these problems and have poor health for people with weak skin.

Therefore, the present invention has been made to solve the problems to be solved as described above, the object of the present invention to automatically perform the sterilization and drying of the laundry to provide convenience to the user, and as another object Provides an automatic laundry sterilization dryer and control method which detects the fluorescent substance contained in the detergent added during washing to detect the fluorescent substance of the residual detergent so that the user can recognize whether the laundry is thoroughly rinsed. There is.

In order to achieve the above object, the sterilizing dryer of the present invention, the dryer 10 is a key button 104 for the operation operation of the front door 101 and the dryer 10 to be able to put the laundry in front of it. Is installed, the dryer enclosure 100 having an air inlet 202 and an air outlet 201 at the rear, a heater 404 for quickly drying laundry inside the dryer enclosure 100, and heated air A blowing fan motor 403 for forcibly discharging the gas, a circular rotating hanger 301 installed rotatably in the vertical direction to uniformly dry the laundry introduced by rotation, and the rotating hanger 301.

Characterized by consisting of the main control unit 501 to control the notification.

The control method of the sterilization drying apparatus in the present invention, when the user gives an operation start command through the key button;

The CPU in the main controller detects this and performs sterilization drying and fluorescent material detection in the following way.

 First, if the front door is closed to determine whether the front door is closed by rotating the rotating hanger and using the camera mounted on the inside to take a first picture of the shape of the laundry on the hanger. In the photographing method, after rotating the rotating hanger so that the laundry is located in front of the camera, the lamp is stopped for a while and only the ultraviolet germicidal lamp is turned on and photographed. When the UV germicidal lamp is turned on, some visible light is emitted in addition to the ultraviolet rays having the strongest sterilizing power of 253.7 nm, so the camera captures the shape of the laundry reflected by the visible light emitted from the germicidal lamp.

 Next, turn on the luminous lamp and take a second picture of the same laundry to determine the presence and location of the fluorescent material reacting to the ultraviolet light of 315-400 nm wavelength emitted from the luminous lamp.

  Determination of the presence or absence of the fluorescent substance, extract the shape of the laundry from the first image taken to find the outline of the laundry and find the part where the shade is raised above a certain threshold by superimposing the second image taken within the outline.

This operation is repeated as many times as the number of laundry is put in, and each sensing state is represented in the figure on the liquid crystal display device installed in the front display part and the part where the fluorescent material is detected.

If there is laundry with fluorescent material detected, the user can select whether to continue drying.If there is no laundry with fluorescent material detected, the UV sterilization lamp is turned on periodically to apply ultraviolet light to the laundry. Investigate and sterilize. At this time, the hanger should be rotated periodically so that the ultraviolet rays can be evenly applied to the laundry.

 When drying is in progress, the heating heater is controlled by sensing the temperature with a temperature sensor so that the temperature inside the dryer does not exceed a certain limit.

Whether or not the drying is completed, it may be determined that the drying is complete when the humidity drops below a preset value by using a humidity sensor installed in the air discharge unit.

Alternatively, it is possible to determine that drying is completed when the humidity value is memorized before the start of drying and the humidity is lowered again after the humidity rises and the temperature is lowered to the vicinity of the first stored humidity value. However, if the drying is in progress for a while and then restarted, the completion of drying cannot be determined by the humidity value first remembered.

Drying completion can also be determined by decreasing slope after increasing humidity. In order to determine the completion of such drying, it may be desirable to apply a combination of the above-described methods.
