Abstract
A supply port receives supply of washing liquid. An oscillation chamber oscillates the washing liquid supplied through the supply port. A jetting section jets the washing liquid oscillated in the oscillation chamber to the outside. The jetting section includes a passage connecting the oscillation chamber and the outside. The washing liquid enters the passage from the oscillation chamber through an entrance, passing through the passage, and emitted through an exit to the outside. A jet port is provided between the entrance and the exit, having a narrower width than those of the entrance and the exit. An outer guide connects the jet port and the exit. An inner guide connects the entrance and the jet port, and configured to conduct the liquid oscillated in the oscillation chamber to the outer guide.
Claims19
A washer nozzle, comprising:
- a supply port configured to receive supply of liquid;
- an oscillation chamber configured to oscillate the liquid supplied through the supply port;
- and
- a jetting section configured to jet the liquid oscillated in the oscillation chamber to the outside,
- wherein the jetting section includes a passage connecting the oscillation chamber and the outside, and includes:
- an entrance where the liquid enters the passage from the oscillation chamber;
- an exit where the liquid is emitted from the passage to the outside;
- a jet port provided between the entrance and the exit, having a narrower width than those of the entrance and the exit;
- an outer guide including a first planar guide surface and a second planar guide surface directly connecting the jet port and the exit, the first and second planar guide surfaces of the outer guide diverging in a direction of flow;
- and
- an inner guide including a first guide surface and a second guide surface directly connecting the entrance and the jet port, the first and second guide surfaces of the inner guide converging in a direction of flow, the first guide surface of the inner guide being configured to orient the liquid oscillated in the oscillation chamber and hitting against the first guide surface of the inner guide toward the second planar guide surface of the outer guide to hit against the second planar guide surface of the outer guide, and the second guide surface of the inner guide being configured to orient the liquid oscillated in the oscillation chamber and hitting against the second guide surface of the inner guide toward the first planar guide surface of the outer guide to hit against the first planar guide surface of the outer guide,
- wherein the oscillation chamber is configured to advance the liquid along a reference axis that bisects the supply port and the oscillation chamber, and to repeatedly and reciprocally change a travelling direction of the liquid within a range between a first direction and a second direction,
- wherein an outer central line extending toward the exit is equidistant between the first and second planar guide surfaces of the outer guide and is not parallel with the reference axis, and
- wherein the reference axis passes between the first and second planar guide surfaces of the outer guide.
