That is, one longitudinal end of the vane 400 is adjacent to the left side wall (not shown) of the washing tub 30 and the other longitudinal end of the vane 400 is adjacent to the right side wall (not shown) of the washing tub 30 .

The vane 400 may be injected from fixed nozzles (not shown) and linearly reciprocated along the spray direction of the wash water. That is, the vane 400 can linearly reciprocate along the front-back direction of the washing tub 30. [

Accordingly, the linear injection structure including the fixed nozzles (not shown) and the vane 400 can clean the entire area of the washing tub 30 without a blind spot. It is different from the case where the washing water can be sprayed only within the range of the turning radius in the case of the rotating nozzles.

The fixed nozzles (not shown) may include a left fixed nozzle (not shown) disposed on the left side of the washing tub 30 and a right fixed nozzle (not shown) disposed on the right side of the washing tub 30.

The rotary nozzles 313 and the fixed nozzles (not shown) can spray wash water independently of each other. Further, the left fixing nozzle (not shown) and the right fixing nozzle (not shown) can also independently spray the washing water.

The washing water injected from the left fixed nozzle (not shown) is reflected only to the left area of the washing tub 30 by the vane 400, and the washing water injected from the right fixed nozzle (not shown) 30). ≪ / RTI >

Therefore, the dishwasher 1 can independently clean the left and right sides of the washing tub 30 separately. Needless to say, unlike the present embodiment, it is needless to say that it is not necessarily divided only into the left and right sides, but it is possible to divide it into further subdivisions according to necessity.
