JPS5861047A - Raindrop removing device for car side window - Google Patents

Abstract

PURPOSE:To satisfactorily secure the field of side view while surely removing raindrops adhered to a side window by providing, on a car door, a nozzle connected to a fan which makes ventilation backwardly from the front end of the external surface of the side window. CONSTITUTION:A fan 6 provided with blade wheels (not illustrated) turned by a motor 8 in a casing 7 is installed on a location close to a door 3 within an engine room 2. On the other hand, on the door 3 a nozzle 9 is provided being oriented backwardly from the front end of the outer periphery of an elevatable side window 4. And, the basic end part of said nozzle 9 is connected to the discharge opening 7a of the casing 7 via a bellows shaped blast pipe 10 and a coupling pipe 11. According to a raindrop removing device constructed in this way, blow-off air is injected backwardly from the front end of the side window 4, so that raindrops that have adhered to or try to adhere to the side window 4 can be satisfactorily blown off.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a raindrop removal device for a side window of an automobile, and its purpose is to remove raindrops adhering to the side window of an automobile during southern weather, thereby improving visibility through the side window. Droplet removal device for car side windows that can be secured! A first embodiment of the present invention will now be described with reference to FIGS. 1 to 4. In FIG. 1, numeral 1 denotes a car body, and as is well known, a fender mirror 1a.

It has an engine room 2, a door 3, etc. and door 5
A well-known Zytowind 4 is installed on the seat so that it can be raised and lowered. 5 is a side window raindrop removal device, which will be described in detail below with reference to FIG. ] and a drive motor 8. Reference numeral 9 denotes a nozzle, which is attached to the door 3 so as to point rearward from the front end of the outer surface of the side window 4. The base end of A/9 is connected to the casing 7 of the blower 6 through the blower pipe 10 and the connecting pipe 11.
7a. Therefore, -1- air pipe 10
is a bellows-shaped material that is flammable (~maybe Ik
As shown in FIG. 3, the air pipe 10 is located at the hinge portion 6a of the door 3, and therefore, when the door 3 is opened and closed, the air pipe 10 forms a ridge that is bent as shown in FIG. 1
- The effect of the above configuration will be described based on experiments conducted by the present invention K.

If the 7γ^ and size of the historical equipment described in - in this example can be carried in advance, then the blower 6... Full load "1" current, 3.5Δ・1

When the blower 6 is operated, air is sucked in from the suction port 7b of the casing 7, passes through the connecting pipe 11 and the blower pipe 10, and is ejected from the nozzle 9, as shown by the large door in Figure 1. At this time, the speed of the air flow ejected from the nozzle 9 (calculated value) is . This ejected air is directed rearward from the edge of the side window 40 and has a jet height force, so that the water droplets (mountain #) adhering to the side window 4 are blown away by the ejected air. The area where the water droplets were blown off is as shown by dimensions C and D in Fig.
Met.

According to this embodiment, even in rainy weather, raindrops that have adhered to or are about to adhere to the side windows 4 can be blown away, so that a good visibility can be ensured through the side windows 4. Therefore, it is possible to improve the safety of each vehicle.

By the way, a so-called wiper device is well known as a device for removing raindrops, but although it is suitable for the front windshield of an automobile, it cannot be used for side windows. That is, in the case of a side window, since the side window itself moves up and down, the wiper device u whose wiper gold film is in direct contact with the side window impedes its up and down movement]7, and (1!
However, problems such as IM miscellaneous problems occur.

In this regard, according to this embodiment, all the air blown by the blower B is used, so the size is 1! There is no problem in raising and lowering the window 4, and the structure is simple 1-i.

FIG. 5 shows a third embodiment of the present invention, which differs from the second embodiment in that the blower 6 is provided inside the door 5. Therefore, in the third embodiment, the blower 6
The communication structure between the nozzle/I/9 and the nozzle/I/9 can be simplified.

FIG. 6 shows a third embodiment of the present invention, in which the device 5 of the present invention is applied to an automatic JG for dIM export in which the door 3 is provided with a side mirror 12. However, unlike the second embodiment, in this third embodiment, the rear window 4 can be completely passed through and the rear mirror 12 can be viewed in rainy weather, further improving the safety of driving. obtain.

As explained above, according to the present invention, it is possible to remove raindrops that tend to adhere to the side windows during rainy weather, thereby ensuring good visibility, and furthermore, eliminating the possibility of any hindrance to the raising and lowering of the side windows. It is possible to provide a raindrop removal device for a side window of an automobile that has excellent effects such as a simple structure.
