Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a window washer device, and more particularly to a window washer device for simplifying a washer liquid supply structure for supplying a washer liquid to a front window shield glass of a vehicle such as an automobile.

[0002]

2. Description of the Related Art Conventionally, vehicles such as automobiles are provided with a window washer device for cleaning dirt on a front window shield glass. As an example of this window washer device, a wiper blade on a driver's seat side and a passenger seat are provided. JP-A-5-3015 discloses a window washer device for wiping a front window shield glass with two wiper blades including a wiper blade on the side.
No. 64, and the configuration disclosed in this publication will be described below.

As shown in FIG. 12, a window washer apparatus 100 includes a washer tank 101, a washer pump 102, nozzles 104 and 106, a piping 10 for connecting these components, and the like.
8 and 110, which are within the wiping range 114 of the wiper blade 112 on the driver's seat side in a high-speed running state, and at least the wiper blade 11 on the driver's seat side.
2. Wiper blade 11 at lower inversion position 112A
The washer fluid lands on the front window shield glass 116 on the front and rear end sides of the wiper blade 2 so that the wiper blade on the driver's seat side can be used not only in a stationary state or a normal running state but also in a high speed state. 112
The washer fluid spreads over the wiping area of the wiping.

[0004]

However, in such a window washer device, the left and right nozzles 10 are provided.
From the injection ports formed two by two on each of 4, 106,
Wiping range 11 of wiper blade 112 on the driver's seat side
4 and the two landing points Q3 and Q4 within the wiping range 122 of the wiper blade 120 on the passenger's seat side. Therefore, two left and right nozzles 104 and 106 are required, and piping 1 to the left and right nozzles 104 and 106 is required.
08 and 110 are required, the number of parts is increased, and the cost is increased.

[0005] In order to improve this, a single nozzle is provided with the washer liquid 1 at each of the landing points Q1, Q2, Q3 and Q4.
It is conceivable to provide four injection ports for injecting 24, but this configuration makes the structure of the nozzle too complicated, and in this case also increases the cost.

In view of the above, an object of the present invention is to provide a window washer device having a simple structure without impairing the cleaning performance of a glass surface.

[0007]

According to the first aspect of the present invention,
In a window washer device for wiping a window with two or more wiper blades, a washer liquid injection port for injecting a washer liquid into a wiping range where a wiping range of one wiper blade overlaps a wiping range of another wiper blade. And a nozzle having:

Accordingly, the washer liquid injected from the washer liquid injection port formed in one nozzle into the wiping area where the wiping area of one wiper blade overlaps the wiping area of the other wiper blade. Thus, both the wiping range of one wiper blade and the wiping range of another wiper blade can be cleaned. In addition, it is not necessary to provide separate nozzles for the wiping range of one wiper blade and the wiping range of another wiper blade, and the number of injection ports for the washer liquid can be reduced. The structure becomes simple.

According to a second aspect of the present invention, there is provided a window washer device for wiping a front window with a wiper blade on a driver's seat side and a wiper blade on a passenger's seat side.
A single nozzle with two washer fluid injection ports,
A first landing point, which is a landing point of the washer fluid injected from the first washer fluid injection port, is within a wiping range on a rear end side of a half of a driver's seat side wiper blade;
The second landing point, which is the landing point of the washer fluid injected from the washer fluid injection port, overlaps the wiping range of the driver's seat side wiper blade with the wiping range on the rear end side of half of the passenger seat side wiper blade. Within the wiping range, the third
The third landing point, which is the landing point of the washer liquid injected from the washer liquid injection port, is within the wiping range on the tip side of half of the front passenger side wiper blade.

[0010] Therefore, of the three landing points, the second landing point is within the wiping range where the wiping range of the driver's seat side wiper blade and the wiping range on the rear end side of the half of the front passenger side wiper blade overlap. , The entire wiping range of the wiping range of the driver's side wiper blade and the wiping range of the front passenger's side wiper blade is washed by the washer liquid injected from the three washer liquid injection ports formed in one nozzle. it can. Therefore, it is not necessary to provide separate nozzles for the wiping range of the wiper blade on the driver's seat side and the wiping range of the wiper blade on the passenger's side, and the injection port of the washer liquid formed in the nozzle is not required. Since there is no need to use four, the structure is simplified.

According to a third aspect of the present invention, there is provided a window washer device for wiping a front window with a wiper blade on a driver's seat side and a wiper blade on a passenger's seat side.
A single nozzle with two washer fluid injection ports,
A first landing point, which is a landing point of the washer fluid injected from the first washer fluid injection port, is within a wiping range on a rear end side of a half of a driver's seat side wiper blade;
The second landing point, which is the landing point of the washer liquid injected from the washer liquid injection port, is the wiping range where the wiping range of the driver's seat side wiper blade overlaps the wiping range on the tip side of half of the passenger seat side wiper blade. Within the range, the third
The third landing point, which is the landing point of the washer liquid injected from the washer liquid injection port, is within the wiping range on the rear end side of half of the passenger seat side wiper blade.

Therefore, of the three landing points, the wiping range of the driver's seat side wiper blade and the wiping range of the front end side of the wiper blade on the passenger's seat side overlap with the wiping range of one half. The entire wiping range of the wiping range of the driver's side wiper blade and the wiping range of the passenger's side wiper blade can be cleaned by the washer liquid injected from the three washer liquid injection ports formed in the above. Therefore, it is not necessary to provide separate nozzles for the wiping range of the wiper blade on the driver's seat side and the wiping range of the wiper blade on the passenger's side, and the injection port of the washer liquid formed in the nozzle is not required. Because there is no need to make four,
The structure becomes simple.
