Abstract

PROBLEM TO BE SOLVED: To prevent infiltration of water into an air sucking hole by forming a guard in the air sucking hole arranged on the under surface side for mixing air in wash water blown out of a nozzle upper surface. SOLUTION: A diametrically contracted orifice passage 3 is formed on the tip side of a wash water passage 2 arranged in a nozzle 1, a negative pressure chamber 4 is arranged on the tip side of the passage 3, and a blowout hole 5 for blowing out wash water is formed on the upper surface 1a side. Next, an air sucking hole 6 is opened on the under surface 1b side of the nozzle 1 so as to communicate with the chamber 4, and a guard part 7 is arranged downward in a projecting shape from an under surface 1b on the opening end outer periphery to drain and drop water dripping by going along the nozzle 1. Or the air sucking hole is arranged on the tip side of the nozzle, and the guard part for preventing infiltration of water into the air sucking hole is formed on the periphery to thereby reliably prevent infiltration of water into the air sucking hole to prevent the air sucking hole from being blocked up by water, and since air can be stably mixed in the wash water, soft cleaning by bubble water can be always secured.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view of a nozzle of a local cleaning apparatus according to a first embodiment. In the nozzle 1, a flow path 2 through which cleaning water passes is formed. A reduced-diameter flow path 3 is formed, and a negative pressure chamber 4 is formed at the tip end side of the reduced-flow path 3. On the upper surface 1 a side of the negative pressure chamber 4, ejection holes 5 and 5 for jetting cleaning water are formed. The air suction hole 6 is opened on the lower surface 1 b side of the nozzle 1 in communication with the negative pressure chamber 4. A guard portion 7 is formed on the outer periphery of the opening end of the air intake hole 6 so as to protrude downward from the lower surface 1b. The guard portion 7 drains water dripping down the nozzle 1 and drops it. The guard portion 7 prevents the air inlet hole 6 from being blocked by water.

In such a structure, when the washing water flowing in the flow path 2 is restricted by the restriction flow path 3 and then spreads at a stretch in the negative pressure chamber 4, a negative pressure is generated in the negative pressure chamber 4. Then, air can be drawn into the negative pressure chamber 4 from the air inlet hole 6 by the negative pressure, and the air can be mixed into the cleaning water, and the cleaning water mixed with the air can be well jetted from the jet holes 5 and 5. It will be. If the nozzle 1 is made of a material such as water-repellent Teflon, for example, the guard portion 7 allows the water drops to drop better, thereby more reliably preventing the air inlet 6 from being blocked by water. Can be done.
