Description

dish washer

본 발명은 식기 세척기에 관한 것으로서, 보다 구체적으로는 식기세척기 내부에 설치된 식기바스켓을 향해 세척수를 하향분사할 수 있는 식기세척기에 관한 것이다.The present invention relates to a dishwasher, and more particularly, to a dishwasher capable of spraying down the washing water toward a dish basket installed inside the dishwasher.

도 5는 종래의 식기 세척기의 측면도이다. 이 도면에 도시된 바와 같이, 식기세척기의 외형을 형성하는 외부케이싱(102)내에 설치된 식기세척조(104)의 상부 및 하부에는 식기를 수용하는 상부식기바스켓(110) 및 하부식기바스켓(106)이 각각 설치되어 있다. 상부식기바스켓(110) 및 하부식기바스켓(106)의 하부에는 해당 식기바스켓(110,106)을 향하여 세척수를 상향 분사하는 상부분사노즐유니트(114) 및 하부분사노즐유니트(108)가 각각 설치되어 있다.5 is a side view of a conventional dish washer. As shown in the figure, upper and lower dish baskets 110 and lower dish baskets 106 for receiving dishes are disposed on the upper and lower portions of the dish washing tank 104 installed in the outer casing 102 forming the outer shape of the dish washing machine. Each is installed. An upper injection nozzle unit 114 and a lower part nozzle unit 108 for spraying the washing water upward toward the corresponding dish baskets 110 and 106 are respectively installed at the lower portions of the upper table basket 110 and the lower table basket 106.

각 분사노즐유니트(114,108)는 세척수의 수압에 의해 회전하면서, 세척수를 상향분사하여 각 식기바스켓(110,106) 내에 수용된 식기를 세척한다. 상부분사노즐유니트(114)는, 식기세척조(104)의 하부로부터 식기세척조(104)의 측벽을 따라 상향 연장된 다음 절곡되어 있는 세척수공급관(116)의 자유단부에 연결관(118)으로 연결되어 세척수를 공급받는다.Each jet nozzle unit 114, 108 rotates by the water pressure of the washing water, and sprays the washing water upward to wash the dishes contained in each of the dish baskets 110, 106. The upper spray nozzle unit 114 is connected to the free end of the washing water supply pipe 116 extending upward from the lower portion of the dish washing tank 104 along the sidewall of the dish washing tank 104 and then bent to the connecting pipe 118. Get the wash water.

이러한 구성에 의하여, 식기세척기가 세척개시할 때에는, 각 식기바스켓(110, 106)의 하부에 설치된 각 분사노즐유니트(114, 108)가 회전하면서, 세척수를 상향분사하여 식기를 세척하게 된다. 이 때, 세척을 마친 오염된 세척수가 각 식기바스켓(110, 106)을 다시 통과하여 식기세척조(104) 하부로 떨어지기 때문에, 각 식기바스켓(110, 106)에 수용된 식기가 재오염됨으로써, 식기세척 효과가 저하된다는 문제점이 있다. 또한, 각 식기바스켓(110,106)의 하부에서만 세척수를 상향분사하여 식기를 세척하기 때문에, 식기의 전 부위에 세척수가 골고루 분사되지 못하여 세척성능이 떨어지게 된다.With this configuration, when the dishwasher starts washing, the spray nozzle units 114 and 108 installed at the lower portions of the dish baskets 110 and 106 rotate, and the washing water is sprayed upward to wash the dishes. At this time, since the contaminated washing water that has been washed passes through each of the dish baskets 110 and 106 again and falls to the lower portion of the dish washing tank 104, the dishware accommodated in each of the dish baskets 110 and 106 is recontaminated. There is a problem that the cleaning effect is reduced. In addition, since the washing water is sprayed upward only from the lower portions of the respective dish baskets 110 and 106, the washing water is not evenly sprayed to all parts of the dishes, and the washing performance is lowered.

따라서, 본 발명의 목적은, 식기세척조의 상부영역에 설치되어 세척수를 하향분사하는 보조분사노즐을 마련하여, 식기세척 효과가 향상되는 식기세척기를 제공하는 것이다.Accordingly, an object of the present invention is to provide a dish washer installed in the upper region of the dish washing tank to provide an auxiliary spray nozzle for spraying the washing water downward, thereby improving the dish washing effect.
