Abstract: A dish washer is disclosed. The dish washer has improved washing efficiency while being constructed in a compact structure. A general dish washer is an apparatus that injects wash water to dishes so as to wash the dishes, and dries and/or sterilizes the washed dishes. The washer according to the present invention includes a filter unit (170) filtering at least some of the wash water injected form a tub (1), fallen downward, and directed to a collection part of sump (20).

Abstract: A dish washer and a control method thereof are disclosed. The dish washer includes a UV sterilization device (60) capable of sterilizing inside of the dish washer and a fan (11) capable of exhausting air in a tub (2) outside. A controller (80) controls the UV sterilization device (60) to sterilize the inside of the dish washer by using ultraviolet rays, and controls the fan (11) to exhaust harmful gas like ozone which may be generated during the sterilization.

Abstract: A dishwasher is provided. The dishwasher includes a tub, a sump, and a sealing member. The tub includes a washing space, and the sump is coupled to a lower portion of the tub. The sealing member is interposed between the tub and the sump, and includes a protrusion contacting one of the tub and the sump to prevent a washing water leakage.

Abstract: The present invention relates to a growth method of nitride semiconductor layer comprising a first step for growing a first nitride 5 semiconductor layer on an AlxGayIn1-x-yN(0<?x<1, 0<y<1, 0<x+y<1) layer, a second step for reducing the thickness of the first nitride semiconductor layer by growth interruption and, a third step for growing a second nitride semiconductor layer having a band gap energy higher than that of the first nitride semiconductor layer on the first nitride semiconductor layer with the to reduced thickness and a light emitting device using the growth method.
