Abstract

PURPOSE:To prevent a sliding sound and the abrasion of a rubber blade part, by making a wiper being not in contact the window glass surface of an automobile, vibrate with a distance of several millimeters kept, and simultaneously performing hot-air jetting and suction of warerdrops, etc. CONSTITUTION:A hot-air conduit 2A, and injection hole 1A communicated with it, and a suction conduit 2B, and a suction groove 1B communicated with the suction conduit 2b are formed on a wiper main body 1 vibrating with a distance of several millimeters kept from a window glass surface 7. An air blower, driven concurrently with switch-ON, is rotated in the hot-air conduit 2A, a valve is opened to jet hot-air from the jetting hole 1A, concurrently a suction fan is rotated to open the valve to suck blown off raindrops, etc., from the suction groove 1B. Consequently the generation of a sliding sound and the generation of abrasion can be prevented without impairing removal effect.

出来るので著しく視界をさまたげない。In order to solve the above-mentioned problems, as shown in FIGS. 1 and 2, it vibrates in parallel with the surface of the window glass while keeping a distance of several millimeters without coming into contact with the surface of the window glass. This is a method in which hot air is jetted from the jet holes 1A of the wiper body 1 to push away water droplets and suck the water droplets pushed away by the suction groove 1B from the surface of the window glass. There is no sliding noise. 2 It is hard to wear and break because it does not contact. 3 Freezing of the surface of the window glass and adhesion of snow are melted by jetting hot air. 4 Since the diameter of the wiper body 1 can be set to about 10 mm, it does not obstruct the view remarkably.

足りる。With the construction shown in FIGS. 1, 2 and 3, high temperature air from the automobile engine is guided to the blower fan 3 and accelerated hot air is jetted from a large number of small diameter injection holes 1A, At the same time, like the blower fan, the suction groove 1B connected to the intake fan 4 that borrows the power of the engine section sucks the water droplets pushed away from the window glass surface, so that the wiper body 1 is parallel to the window glass surface and at an appropriate speed. The purpose can be achieved by vibrating at, and repeating injection and suction. The hot air blown from the jet holes 1A is desired to be as hot and fast as possible, but the suction force of the suction groove 1B is sufficient to be able to absorb water droplets deep in the groove and carry it to the base of the wiper body.

する。1 When driving a car during rain or snow, if the lever or switch is turned on, the fan 3 will rotate, the valve 5 will open, and warm air will blow out from the injection hole 1A and adhere to the surface of the window glass. Blow out. 2 At the same time, the intake fan 4 also rotates, the valve 6 opens, and intake is started, and the suction groove 1B sucks raindrops and the like blown out. 3. Simultaneously, the wiper body 1 starts to vibrate in parallel while keeping a distance of several millimeters from the surface of the window glass.
Although the above-mentioned operation can be performed to achieve the purpose of removal, the following points should be taken into consideration when implementing. 4 The vibration speed of the wiper body 1 which is oscillated by borrowing the power of the automobile engine section can be adjusted according to the degree of rainfall such as low speed, medium speed, high speed, etc. 5 In addition, the wiper main suspension 1 needs to vibrate while keeping an equal distance along the curve of the window glass, so the shape is adjusted according to the vehicle type, and the vibration trajectory is not a straight line, as shown in a, a'section of FIG. To 6. Incidentally, if a spring is used as in the conventional wiper device and a hard rubber roller is attached to the tip end portion in order to keep an equal distance, only the shape of the wiper body need be considered. 7 Since muddy water other than rain and snow may be removed in some cases, it is possible to inject wash water as in the conventional wiper device.
