DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washer tank for a headlamp cleaner.

[0002]

2. Description of the Related Art FIG. 5 shows a conventional example of a washer tank used for a headlamp cleaner for discharging a cleaning liquid to a headlamp of a vehicle for cleaning. The washer tank 30 shown in FIG. 1 includes a box-shaped tank main body 32 disposed in a front fender 31 of a vehicle, a headlamp cleaner motor 33 attached to the bottom of the tank main body 32, and an inside of the front fender 31. A breathing box 35 in which a breathing chamber 34 communicating with external air is formed, and a pipe 36 such as a rubber hose that communicates the breathing chamber 34 with a breathing hole of the headlamp cleaner motor 33. Is provided.

[0006] As shown in FIG. 6, the breathing box 35 is provided with a tube material 36 at a bottom nozzle 35 a projecting downward from the bottom surface.
And a breathing pipe 37 is attached to a side nozzle 35b protruding from the side to the side.

According to such a washer tank 30, the cleaning liquid is sucked from the tank body 32 by the rotation of the headlamp cleaner motor 33, and the cleaning liquid is discharged from the headlamp cleaner nozzle 33a toward the headlamp of the vehicle (not shown). it can. In addition, the breathing action (movement of air by heating) accompanying the rotation of the headlamp cleaner motor 33 can be smoothly performed via the pipe member 36 and the breathing chamber 34 communicating with the external air.

Further, when the headlamp cleaner motor 33 performs a breathing operation, the breathing box 35 is disposed above the inside of the front fender 31. The suction into the cleaner motor 33 can be prevented.

[0006]

However, in the case of the above-mentioned washer tank 30, the box-shaped tank main body 3 is provided.
2, a breathing box 35 having a breathing chamber 34 formed therein communicating with the outside air is formed inside the breathing box 35, and the breathing box 35 must be arranged above the inside of the front fender 31. There is a problem in that the structure increases, the structure becomes complicated, and the manufacturing cost rises.

Accordingly, the present invention provides a washer tank for a headlamp cleaner which can prevent water from being sucked in during the respiration of the headlamp cleaner motor and can reduce the manufacturing cost by simplifying the structure. The purpose is to do.

[0008]

SUMMARY OF THE INVENTION The present invention is directed to a headlamp cleaner for storing a cleaning liquid in a tank body and sending the cleaning liquid toward the headlamp by rotating a headlamp cleaner motor attached to a lower portion of the tank body. In the washer tank, a water shielding piece protruding laterally from a side wall of the tank body and an umbrella portion covering an upper part of the water shielding piece form a breathing chamber communicating with external air, and the headlamp cleaner motor has a An upper end portion of a pipe material led out from a breathing hole is made to pass through the water shielding piece and face the breathing room.

[0009]

According to the washer tank for a headlamp cleaner having the above-described structure, the tank main body is exposed to external air by the water shielding piece projecting laterally from the side wall thereof and the umbrella portion covering the upper part of the water shielding piece. Since the communicating breathing chamber is formed and the upper end of the pipe material drawn out from the breathing hole of the headlamp cleaner motor attached to the lower part of the tank body penetrates the water shielding piece and faces the breathing chamber, the headlamp In the event of a respiratory action due to heat generation during operation of the cleaner motor, water from the outside can be blocked by the water shielding piece and the umbrella portion, and suction of water into the headlamp cleaner motor can be eliminated.

[0010] Further, since the water shielding piece protruding laterally from the tank body and the umbrella portion covering the upper part of the water shielding piece form a breathing chamber communicating with external air, the tank body is formed. Together with this respiratory chamber,
The structure is simplified, and the manufacturing cost can be reduced.

[0011]

Embodiments of the present invention will be described below in detail.
Washer tank 1 for headlamp cleaner shown in FIG.
Is a tank-shaped tank body 2 in a front fender 31 of a vehicle and containing a cleaning liquid therein, a headlamp cleaner motor 3 attached to the bottom of the tank body 2, and a side wall of the tank body 2. A respiratory chamber 7 formed by a water shielding piece 4 protruding laterally, a rectangular parallelepiped umbrella section 5 provided on the upper part of the water shielding piece 4 and having an upper surface closed and an open lower surface; And a tube 8 made of a rubber hose or the like which has an upper end portion penetrating the water shielding piece 4 and facing the breathing chamber 7.

As shown in FIG. 2, a gap 6 through which air can flow is provided between the lower end of the umbrella section 5 and the water shielding piece 4, so that the breathing chamber 7 is provided with a water shielding. The upper surface of the piece 4 communicates with outside air.

In FIG. 1, reference numeral 9 denotes a headlamp cleaner nozzle for discharging a cleaning liquid toward a headlamp (not shown) of a vehicle.

As shown in FIG. 3, the water shielding piece 4 can be integrally formed with the through hole 10 of the tube 8 when the lower jar 2a forming the tank body 2 is formed.

As shown in FIG. 2, the umbrella unit 5
When the upper jar 2b forming the tank body 2 is formed, the upper jar 2b can be formed by bending the end of the upper jar 2b. The bent edge 2c is welded to the upper end of the lower jar 2a by welding or the like. Breathing room 7
Can be formed.

According to the washer tank 1 for a headlamp cleaner having the above-described structure, the external air is formed by the water shielding piece 4 protruding laterally from the tank body 2 and the umbrella section 5 covering the upper part of the water shielding piece 4. A breathing chamber 7 communicating with the breathing chamber 7 is formed, and an upper end of a pipe 8 derived from a breathing hole of a headlamp cleaner motor 3 attached to a lower portion of the tank body 2 penetrates through the water shielding piece 4 and faces the breathing chamber 7. In the event of a respiratory action accompanying heat generation during operation of the headlamp cleaner motor 3, water from the outside due to jumping up of a tire or the like is cut off by the water shielding piece 4 or the umbrella section 5, Water suction into the headlamp cleaner motor 3 can be eliminated.

Further, the water-shielding piece 4 protruding laterally from the tank body 2 and the umbrella portion 5 covering the upper part of the water-shielding piece 4 form the breathing chamber 7 communicating with the outside air. The breathing chamber 7 can be formed together with the formation of the tank body 2, so that the structure can be simplified and the manufacturing cost can be reduced.

FIG. 4 shows another example of the respiratory chamber 7. The respiratory chamber 7 A shown in FIG. 4 is arranged so that the side of the upper jar 2 b reaches the vicinity of the water shielding piece 4. In addition, a hanging piece 11 is provided so as to surround the three sides of the pipe member 8, and the lower end of the upper jar 2b is welded to the upper end of the lower jar 2a by welding or the like. Even with such a respiratory chamber 7A, the same operation as in the case described above can be exerted. The present invention is not limited to the embodiments described above, and various modifications are possible within the scope of the invention.

[0019]

According to the present invention described in detail above, since the above-described structure is employed, it is possible to prevent water from being sucked in during the respiration of the headlamp cleaner motor, and to reduce the manufacturing cost by simplifying the structure. Thus, it is possible to provide a washer tank for a headlamp cleaner capable of achieving the following.
