## Abstract

A washer-integrated type wiper apparatus is provided. The washer-integrated type wiper apparatus includes a nozzle cover that is coupled to one side of a bending component of a retainer to support a wiper blade and a hose module that extends in the longitudinal direction in the interior of the retainer and is positioned in the interior of the nozzle cover and is connected to a washer liquid storing tank. Further, a main nozzle is connected in the interior of the nozzle cover to the hose module and is formed to expose a plurality of spray ports to the outside of the nozzle cover and is configured to spray the washer liquid supplied from the washer liquid storing tank through the spray ports. A heater module is installed in the heating area.

## Claims

### Claim 1

A washer-integrated type wiper apparatus, comprising:
a nozzle cover coupled to one side of a bending component of a retainer to support a wiper blade;
a hose module that extends in a longitudinal direction within the retainer and is positioned within the nozzle cover and is coupled to a washer liquid storing tank;
a main nozzle connected in the interior of the nozzle cover to the hose module and formed to expose a plurality of spray ports to the exterior of the nozzle cover and is configured to spray the washer liquid supplied from the washer liquid storing tank through the spray ports; and
a heater module which is installed in a heating area defined at the main nozzle and configured to transfer heat in the direction of the spray ports,
wherein the main nozzle includes:
a spray component disposed to be exposed to the exterior of the nozzle cover, wherein the spray ports are disposed on the exposed lower surface thereof, and the heating area is defined on the upper surface thereof;
a heater module installation component configured to guide an installation passage of the heater module installed in the heating area and formed to be bent in the same direction as a bent direction of the nozzle cover; and
a washer liquid supply component spaced apart from the heater module installation component and integrally connected with the hose module, and configured to supply the washer liquid in the direction of the spray ports.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the main nozzle includes a check valve installed at the washer liquid supply component installed downwardly slanted with respect to the spray ports, and configured to selectively interrupt a supply of the washer liquid which flows in the direction of the spray ports.

### Claim 3 (depends on 1)

The apparatus of claim 1, wherein the heater module is installed at the heater module installation component and includes a water tight cover to provide a water tight passage for the washer liquid.

### Claim 4 (depends on 3)

The apparatus of claim 3, wherein the water tight cover includes a plurality of terminal guide grooves on an exterior circumferential surface of the water tight cover to fix a position of a terminal and obtain a water tight terminal to provide a positive terminal and a negative terminal coupled to the heater module.

### Claim 5 (depends on 1)

The apparatus of claim 1, wherein the main nozzle includes a protrusion member that corresponds to an engaging groove formed at the nozzle cover, and the protrusion member is engaged to be inserted into the engaging groove, to fix the position in the interior of the nozzle cover.

### Claim 6 (depends on 1)

The apparatus of claim 1, wherein an interior of the nozzle cover is configured to be filled with a resin.

### Claim 7 (depends on 1)

The apparatus of claim 1, wherein the nozzle cover is configured to form a same surface as an exterior circumferential surface of the bending component of the retainer.
