In order to achieve the above-mentioned object, the present invention is to wash dishes between an upper nozzle assembly and a lower nozzle assembly in a main body case having a top plate, and to remove the upper nozzle assembly. In the three-dimensional structure, a washing nozzle and a rinsing nozzle are rotatably provided on the nozzle support in two stages, and the washing water is directed from the first washing jet port of the washing nozzle and the first rinsing jet port of the rinsing nozzle toward the tableware. And in a dishwasher that is adapted to spray rinse water downward,
The rinsing nozzle is characterized in that a plurality of second rinsing jet ports are formed so as to open upward so as to jet rinsing water toward the top plate and its vicinity.

[0008]

In the dishwasher according to the present invention, the second nozzle formed on the rinsing nozzle of the upper nozzle assembly during the rinsing process.
The rinse water sprayed from the rinse spray port is sprayed in a direction other than the tableware, that is, toward the top plate and its vicinity. Since the cleaning nozzle and the rinsing nozzle are arranged in upper and lower two stages, a part of the rinsing water cleans the cleaning nozzle, and the rinsing water directed to the top plate of the main body case and its vicinity has the same structure. The top plate and its vicinity are washed, and the top plate is washed and the rinsing water that drops falls cleans the nozzle support. By rinsing and washing as described above, impurities such as dirt and foreign substances attached to each portion during the washing process are rinsed and washed down. Although some of the impurities may be reattached to the dishes, since the rinse nozzle of the upper nozzle assembly has the first rinse injection port that sprays the rinse water toward the dishes,
Of course, the dishes are rinsed cleanly. In this way, the washing chamber is always kept in a hygienic condition.
