Description

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 in a headlamp cleaner for discharging a cleaning liquid to a vehicle headlamp for cleaning. The washer tank 30 shown in the figure is a box-shaped tank main body 32 arranged in a front fender 31 of a vehicle, a headlamp cleaner motor 33 attached to the bottom of the tank main body 32, and the inside of the front fender 31. A breathing box 35 which is disposed on the upper side of the breathing chamber 34 and which communicates with the outside air inside, and a pipe member 36 such as a rubber hose which communicates between the breathing chamber 34 and the breathing hole of the headlamp cleaner motor 33. It is equipped with.

As shown in FIG. 6, the breathing box 35 has a bottom surface nozzle 35a projecting downward from a bottom surface thereof, and a tubing member 36 formed in
And a breathing tube 37 is attached to a side surface nozzle 35b protruding laterally from the side surface.

According to such a washer tank 30, the cleaning liquid is sucked from the tank main 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. The breathing action (movement of air by heating) accompanying the rotation of the headlamp cleaner motor 33 can be smoothly performed through the breathing chamber 34 communicating with the pipe material 36 and the external air.

Further, when the headlamp cleaner motor 33 breathes, the breathing box 35 is arranged above the inside of the front fender 31. It is possible to prevent the cleaner motor 33 from being sucked into the cleaner motor 33.

[0006]

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

Therefore, the present invention provides a washer tank for a headlamp cleaner, which can prevent the inhalation of water during the breathing action 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 for a headlamp cleaner for storing a cleaning liquid in a tank main body and delivering the cleaning liquid toward the headlamp by the rotation of a headlamp cleaner motor attached to the lower portion of the tank main body. In the washer tank, a water-shielding piece protruding laterally from the side wall of the tank body and an umbrella portion covering the upper portion of the water-shielding piece form a breathing chamber that communicates with external air, and the headlamp cleaner motor The upper end portion of the tubular member led out from the breathing hole penetrates the water shielding piece and faces the breathing chamber.

[0009]

According to the washer tank for a headlamp cleaner having the above-mentioned structure, the tank main body is protected from the outside air by the water shielding piece protruding laterally from the side wall and the umbrella portion covering the upper portion of the water shielding piece. Since the breathing chamber that communicates is formed and the upper end portion of the pipe material led out from the breathing hole of the headlamp cleaner motor attached to the lower portion of the tank main body penetrates the water shielding piece and faces the breathing chamber. When breathing due to heat generation during operation of the cleaner motor, water from the outside can be blocked by the water shield piece and the umbrella portion, and it is possible to prevent water from being sucked into the headlamp cleaner motor.

Further, since the breathing chamber communicating with the outside air is formed by the water shielding piece protruding laterally from the tank body and the umbrella portion covering the upper part of the water shielding piece, the tank body is formed. Can form this breathing chamber with
The structure can be simplified and the manufacturing cost can be reduced.

EXAMPLES Examples of the present invention will be described in detail below.
Washer tank 1 for headlamp cleaner shown in FIG.
Is a box-shaped tank main body 2 which is disposed in the front fender 31 of the vehicle and contains a cleaning liquid therein, a headlamp cleaner motor 3 attached to the bottom of the tank main body 2, and a side wall of the tank main body 2. A breathing chamber 7 formed by a water-shielding piece 4 projecting laterally and a rectangular parallelepiped-shaped umbrella portion 5 provided on the upper portion of the water-shielding piece 4 with its upper surface closed and its lower surface opened; and the headlamp cleaner motor. 3, a pipe member 8 made of a rubber hose or the like, which is led out from the breathing hole 3 and has an upper end portion which penetrates the water shielding piece 4 and faces 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 portion 5 and the water shielding piece 4, whereby the breathing chamber 7 is covered with water. The upper surface of the piece 4 communicates with the outside air.

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

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

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

According to the headlamp cleaner washer tank 1 having the above-described structure, the outside air is provided by the water shielding piece 4 projecting laterally from the tank body 2 and the umbrella portion 5 covering the upper portion of the water shielding piece 4. A breathing chamber 7 communicating with the breathing chamber 7 is formed, and an upper end portion of a pipe material 8 led out from a breathing hole of a headlamp cleaner motor 3 attached to a lower portion of the tank body 2 penetrates the water shielding piece 4 to reach the breathing chamber 7. Therefore, when breathing due to heat generated during the operation of the headlamp cleaner motor 3, water from the outside due to the bounce of the tires or the like is blocked by the water blocking piece 4 and the umbrella portion 5, It is possible to eliminate the suction of water into the headlamp cleaner motor 3.

Further, the water shielding piece 4 protruding laterally from the tank main body 2 and the umbrella portion 5 covering the upper portion 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, and the structure can be simplified and the manufacturing cost can be reduced.

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

[0019]

According to the present invention described in detail above, since it has the above-mentioned structure, it is possible to prevent the inhalation of water during the breathing action of the headlamp cleaner motor and to reduce the manufacturing cost by simplifying the structure. It is possible to provide a washer tank for a headlamp cleaner capable of achieving the above.
