Abstract
The present invention relates to a spray nozzle for washing, in which: a linear spray inlet and a spiral spray inlet are integrally formed in one nozzle body, and thus, linear and spiral washing water can be selectively sprayed by operating organically; the lower end of a nozzle tip, which forms the spiral washing water, moves circumferentially around the axis, and the upper end makes linear contact within a packing, thereby preventing abrasion caused by friction and forming the spiral washing water without frictional resistance even in the case of weak water pressure; and when forming the spiral washing water, a backflow preventing member closes the linear jet inlet, and thus, backflow can be prevented, thereby enabling leakage prevention of washing water and a stable operation.
Claims7
A spray nozzle for washing, the spray nozzle comprising:
- a nozzle body (100);
- a linear spray inlet (200) formed on one side of the nozzle body (100);
- a spiral spray inlet (300) formed under the linear spray inlet (200);
- a rotating part (400) mounted in a rotation space (110) of the nozzle body (100) and rotated by washing water introduced through the spiral spray inlet (300);
- a spiral action imparting part (500) configured to be mounted on an upper part of the rotating part (400) and to give spiral action to the washing water introduced through the spiral spray inlet (300) while being moved circumferentially by the rotating part (400);
- and
- a backflow preventing part (600) mounted to the linear spray inlet (200) to open a linear spray flow path (210) when washing water flows into the linear spray inlet (200) and close the linear spray flow path (210) when washing water flows into the spiral spray inlet (300) to prevent backflow,
- wherein when washing water flows into the linear spray inlet (200), the backflow preventing part (600) stops a stop protrusion (430) of the rotating part (400) so that the washing water is sprayed in a liner shape, and when washing water flows into the spiral spray inlet (300), pressure is generated inside the nozzle body (100), and thus the backflow preventing part (600) moves away from the stop protrusion (430) and closes the linear spray flow path (210) and simultaneously, the washing water is sprayed in a spiral shape.
