As shown in Fig. 1, a conventional automobile window cleaning device has a washer tank 1 mounted in the front of the vehicle body.
A front washer pump 2 is attached to this washer tank 1, this front washer pump 2 is connected to a front nozzle 5 provided near a window at the front of the vehicle body through a single vinyl tube 4, and the washer pump 2 is operated. Washer liquid is sprayed from a front nozzle 5 to the front window of the vehicle body to wash the front window and secure the front visibility. In order to improve safety, an attempt was made to clean the windows at the rear of the car body, and as shown in Figure 1, a rear wash pump 3 was added to the wash tank 1 mounted on the front of the car body, and this washer pump 3 and the car body were washed. Rear nozzle 6 installed near the rear window
A device is adopted in which the windows are connected by a single vinyl tube 4, and a rear washer pump 3 is operated to spray washer fluid from a rear nozzle 6 onto the rear window of the vehicle body for washing. This is because it is not possible to install a wash tank at the rear of the car body due to reasons such as increasing cost or lack of space to install it on the car body. Therefore, a rear wash pump 3 is attached to the wash tank installed at the front of the car body, and from there the wash tank is installed at the front of the car body. A common structure was to connect the rear nozzle with a tube. However, since the distance between the washer tank 1 and the rear nozzle 6 is long, this device has the following disadvantages that could not occur if the washer fluid was injected from the front nozzle 5, which is close to the washer tank 1. Ta.

Since the rear nozzle 6 is far from the rear washer pump 3 and is located higher than the water level in the washer tank 1, the water level in the vinyl tube 4 drops to the same level as the water level in the washer tank 1 when not in use. If the diameter of the tube is large, the flow rate of the washer fluid will be slow;
Even when the pump is activated, the washer fluid is not sprayed immediately and there is a time delay, which is a fatal problem from a safety standpoint as a device for cleaning dirty windows while the vehicle is running. Reducing the diameter of the tube in order to increase the flow rate of the washer fluid will only increase the pipe resistance because the tube is long, which will reduce the efficiency of the washer pump and reduce the flow rate of the washer fluid. There is a disadvantage that it is not possible to inject a sufficient amount of washer liquid. Therefore, a vinyl tube 4 connecting between the wash pump 3 and the rear nozzle 6 is installed.
It was extremely difficult to select the diameter.

A structure in which a check valve is inserted in the middle of the vinyl tube 4 that connects the rear washer pump 3 and the rear nozzle 6 to keep the water level of the washer fluid close to the rear nozzle 6, and the washer fluid is immediately injected may also be considered. There were problems such as increased costs, the addition of a mechanism to prevent air trapping, and the inability to obtain sufficient pressure and flow rate due to the check valve acting as resistance.

The present invention was developed in view of these points, and is an automobile window cleaning device that connects a washing tank mounted at the front of the vehicle body to a rear nozzle at the rear of the vehicle body through a tube, and can inject washing fluid at the same time as the washing pump is driven. The purpose is to provide equipment.

The present invention consists of a washer tank attached to the front of the vehicle, a front washer pump and a rear washer pump attached to the washer tank, and a front nozzle and a rear nozzle attached to the front of the vehicle, each of which is located above the mounting position of the washer tank. The rear nozzle attached to the
In the automobile window cleaning device comprising a tube connecting the washer pump and a nozzle, the tube connecting the rear washer pump and the rear nozzle has one end connected to the rear washer pump and is located at a lower part of the vehicle body below the position where the washer tank is mounted. The tube consists of a large diameter tube located at the rear nozzle and extending toward the rear of the vehicle body, and a small diameter tube connected at one end to the rear nozzle and located at the rear of the vehicle body above the wash tank mounting position. The connection position with the other end of the small diameter tube is determined at the wash tank mounting position, the small diameter tube is placed between the wash tank mounting position and the rear nozzle above it, and the large diameter tube is placed below the wash tank mounting position. It is.

As mentioned above, when the washer pump is not operating, the water level of the washer liquid in the washer tank and the water level inside the tube are at the same level, and the washer liquid is at the same level as the water level in the tube, and the washer liquid is at the small diameter near the connecting part between the large diameter tube and the small diameter tube. When reaching the tube and driving the washer pump, the flow rate of the liquid flowing from the pump through the large diameter tube and the flow rate of the liquid reaching the nozzle through the small diameter tube is significantly faster, so the pump Washer liquid is sprayed from the nozzle immediately after driving.

The present invention will be explained below based on the embodiments shown in the accompanying drawings. In FIG. 2, a washer tank 1 is mounted on the front of an automobile 7, and a front washer pump 2 and a rear washer pump 3 are attached to this washer tank 1.
One end of a vinyl tube 4 is connected to this front washer pump 2, and a front nozzle 5 is connected to the other end of the vinyl tube 4. One end of a large-diameter tube 4' made of a vinyl tube is connected to the rear washer pump 3, and is disposed at the lower part of the vehicle body below the position where the washer tank is mounted, and extends toward the rear of the vehicle body. and,
A rear nozzle 6 is provided in the vicinity of the window at the rear of the vehicle body, that is, above the mounting position of the wash tank 1. One end of a narrow diameter tube 8 made of a vinyl tube is connected to this rear nozzle 6 and is disposed at the rear of the vehicle body. It is set up. The connection position between the other end of the small-diameter tube 8 and the other end of the large-diameter tube 4' is determined near the washing tank 1 mounting position, that is, the area where the water level in the washing tank 1 changes. A small diameter tube 8 is disposed between the rear nozzle 6 located at the rear nozzle 6, and a large diameter tube is disposed below the wash tank mounting position. In this case, it is desirable that the connection position between the large diameter tube 4' and the small diameter tube 8 be located on the lower surface of the washer tank 1. It goes without saying that when the inner diameter of the large-diameter tube 4' is R 1 and the inner diameter of the small-diameter tube 8 is R 2 , the relational expression R 1 >R 2 holds true.

As mentioned above, as shown in Fig. 3, the washer liquid in the small diameter tube 8 which is at the same water level as the washer tank 1 has a smaller inner diameter than the thicker vinyl tube 4, so if the flow rate is the same, the flow rate will be lower. makes it faster. Therefore, when the rear washer pump 3 is driven, the rear nozzle 6 of the washer liquid in the small diameter tube 8, which is at the same water level as the washer tank 1, is
The time required to reach this point is significantly improved, and washer fluid injection delays are prevented. Incidentally, by changing the inner diameter of the small diameter tube 8, it is possible to set the injection speed according to the design intention. Furthermore, if the small diameter tube 8 leading to the rear nozzle 6 is passed through the rear pillar 9 as shown in FIG. 2, the sound of the tube hitting the pillar panel due to vibration etc. will be produced, so as shown in FIG. A cushion member 10 made of foamed polyurethane or the like is wrapped and pinned, or a cushion member 11 with adhesive tape is wrapped to prevent the occurrence of hitting noise between the tube and the pillar panel.
