Abstract

A spray washer nozzle for a vehicle may include a nozzle body installed in a hood of a vehicle as a unit for ejecting washer liquid to a windshield, and connected to a hose for supplying the washer liquid and fixedly installed in a hood panel at the same time, and a spray nozzle chip having a passage therein and inserted into a head part of the nozzle body, in which a heat emitter is inserted into and mounted to the passage formed in the interior of the spray nozzle chip such that washer liquid flowing through the passage of the spray nozzle chip is heated while directly contacting the heat emitter.

First claim

What is claimed is:

1. A spray washer nozzle for a vehicle comprising:
a nozzle body installed in a hood of a vehicle as a unit for ejecting washer liquid to a windshield, and connected to a hose for supplying the washer liquid and fixedly installed in a hood panel at the same time;
a spray nozzle chip having a passage therein and inserted into a head part of the nozzle body; and
a heat emitter that is inserted into and mounted to the passage formed in an interior of the spray nozzle chip such that washer liquid flowing through the passage of the spray nozzle chip is heated while directly contacting the heat emitter,
wherein the heat emitter comprises:
a plate-shaped heat emitting element
a terminal mounted to a rear end of the heat emitting element, and
a connector fixed to the nozzle body while being connected to the terminal.

2. The spray washer nozzle of claim 1 , wherein the heat emitter further comprises a sealing pad mounted to a connection portion of the heat emitting element and the terminal, for protecting the terminal from the washer liquid.

3. The spray washer nozzle of claim 1 , wherein the heat emitting element has a hole passing through a thickness of the heat emitting element and is mounted to a vertically intermediate location of the passage located in the spray nozzle chip such that a section of the nozzle automatically has a dual spray nozzle structure while being separated into upper and lower parts.

4. The spray washer nozzle of claim 1 , wherein the heat emitting element of the heat emitter is formed of plastic PTC or ceramic PTC.

5. The spray washer nozzle of claim 1 , wherein the spray nozzle chip comprises an inlet at a rear end thereof through which washer liquid is introduced, an intermediate passage space, and an outlet at a tip end thereof through which the washer liquid is ejected, and two stagnant flow forming spaces are formed at opposite sides of an inner peripheral area of the passage space, and the two stagnant flow forming spaces are partitioned by border walls on opposite sides protruding toward a center of a width of the passage.
