Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a wiper device for a vehicle such as a passenger car, a truck, a bus, a snowplow, a grader, an excavator vehicle, and an electric vehicle, and particularly to a wiper device most suitable for use in a snowfall zone or a cold region.

[0002]

[Prior art]

 The wiper device reciprocates the blade from side to side using the rotational force of the motor via a link mechanism to wipe out rain and snow adhering to the windshield to secure a view ahead of the vehicle. In such a case, inconveniences such as snow, ice, frost, etc., being frozen on the front glass surface and the effect of the wiper device being unable to be exhibited, and the operation of the wiper blade being frozen on the windshield surface while the wiper device is at rest, being inoperable are caused. .

For example, in a snowfall area, snow and cold weather cause snow to adhere to the wiper blade, forming an ice block, damaging the windshield, and causing a gap between the windshield and the blade to produce a wiper. The effect of the device is reduced. Further, in a cold region, there is a problem that the blade freezes on the windshield when the vehicle is parked at night or the like, and the blade does not move.

Conventionally, to solve such a problem, a device in which a hot wire is wired on a windshield, a means for blowing hot air (heated air) toward the windshield, and the like have been proposed. There are also structures that do not freeze on the blade, such as providing a cover or using a material that does not freeze.

[Problems to be solved by the invention]

 However, a device in which a hot wire is wired to a windshield is dedicated to the vehicle, and cannot be installed in a vehicle in which a hot wire is not wired to the windshield, so that there is a problem of lack of versatility to other vehicles.

In addition, the means for blowing hot air toward the windshield needs to warm up the engine and heat the coolant of the engine to a relatively high temperature. In a cold region, a considerable amount of time is required, and it is desired to use it immediately. Drivers and impatient drivers may activate the wiper device before the frozen snow or ice melts on the windshield, damaging the wiper device or damaging the windshield.

[0007] Furthermore, a structure that does not freeze on the blade, for example, a structure provided with a cover or using a material that does not freeze does not solve the above-mentioned problem in wiping during snowfall. Even though it does not freeze, there is a temperature limit.

[0008] The present invention has been made in view of such a point, and an object thereof is to be able to be attached to any vehicle and to wipe off snow, ice, frost, etc. frozen on a windshield surface in a short time. Vehicle wiper device that can quickly peel off even if the wiper blade freezes on the windshield, prevent snow and ice buildup during snowfall, wipe off rain and snow, and ensure good visibility Is provided.
