Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram showing a washing machine according to the present invention.

The sterilization apparatus of the washing machine according to the present invention is installed on the inner side of the case 52 forming the outer as shown in FIG. 2 to wash the laundry 54 and the dehydration tank 56 and the case ( 52 is provided to be opened and closed on the upper side of the cover 68 to prevent the laundry from being separated from the washing tank 54 and the dehydration tank 56, and installed in front of the cover 68 to adjust the operation of the washing machine The control unit 70, the top cover 72 installed behind the cover 68, the water supply device 74 is built, and fixed to the inside of the top cover 72 is supplied from the water supply device 74 Detergent box housing 76 for supplying the washing water to the washing tank 54 and the dehydration tank 56, a detergent box 78 is stored in the detergent box housing 76 and the detergent is stored, and the detergent UV light is installed at the lower end of the box housing 76 according to the control signal of the controller 70. It is configured to include an ultraviolet lamp 80 for generating a.

On the other hand, ultraviolet rays are a wide range of electromagnetic waves with a wavelength of 379 ~ 10nm, excellent in the bleaching and sterilization effect, easily transmit water and transparent materials, but do not pass through opaque materials.

Therefore, the detergent box housing 76 is made of a transparent material through which ultraviolet light can be transmitted to sterilize and disinfect the wash water passing through the detergent box housing 76 during water supply.

In addition, the ultraviolet lamp 80 is provided with a reflecting plate 82 for reflecting the ultraviolet rays generated from the ultraviolet lamp 80 to the upper and lower sides.

Here, the reflective plate 82 is a cylindrical shape in which the upper and lower sides are opened, the ultraviolet lamp 80 is inserted into the inner center, and are formed to extend in the radial direction toward the upper and lower sides, respectively.
