Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wiper deicer device which is attached to a lower part of a front windshield of an automobile mainly for cold regions and melts snow scraped by a wiper by heat of a heater.

[0002]

[Prior art]

 Mainly, a cold region type automobile is equipped with a conventional wiper designer device as shown in FIG. 5 in order to scrape off snow adhering to the front window with a wiper and melt the snow. The wiper de-icer device 1 is arranged outside a lower part of a front window 2 of an automobile. As shown in FIG. 6, the wiper de-icer device 1 includes a wiper de-icer 3 composed of a wide hollow container (4 mm × 17 mm × t0.7 mm) made of sheet metal formed by flatly crushing a pipe in a radial direction, and the wiper de-icer 3. 3 is composed of a tube 4 connected to both sides and a deck heater 5 connected to the tube 4.

As shown in FIGS. 5 and 7, the wiper device 3 is arranged over the entire width of the front window 2 and is attached to a deck 2a below the front window 2 to which the wiper arm 6a of the wiper 6 is attached. It is attached and fixed via 7. Although not shown, the deck heater 5 is provided in the engine room.

That is, the snow on the front window 2 is scraped off by the wiper 6, and the snow collected at the lower edge portion of the front window 2 is melted by the heat of the hot water circulating through the wiper deicer 3.

[0005]

[Problems to be solved by the device]

 Since the above-mentioned conventional wiper de-iser 3 is made of sheet metal, it must be curved to match the curvature of the front window 2 and must also be formed to match the width of the front window 2. Further, since the curvature of the front window 2 is different for each vehicle type, the wiper de-icer 3 cannot be shared, and the wiper de-aiser 3 must be individually designed and manufactured.

The present invention has been made in view of the above circumstances. The purpose of the present invention is to easily bend the wiper deaisa by hand, to adapt it to various front window shapes, and to make it suitable for many types of vehicles. The purpose is to provide a wiper device that can be shared.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a wiper designer device in which warm water of a heater is flowed through a wiper designer arranged at a lower portion of a front window to melt snow scraped by the wiper. Composed of a bent flexible pipe.

[0008]

[Action]

 According to the wiper de-icer device configured in this way, since the wiper de-icer is a flexible pipe with a circular cross-section, it can be easily bent to fit the shape of various front windows before being mounted on the vehicle body, and when it is bent, the front Can be set in the wind.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. It should be noted that the same components as those described in the related art are designated by the same reference numerals and the description thereof will be omitted. 1 and 2 show a wiper de-icer device 10, and 11 is a wiper de-icer.

The wiper deicer 11 is formed of a flexible pipe that is bent in a meandering shape (bellows) with a circular cross section. As shown in FIG. 3, the wiper deicer 11 is fixedly attached to the lower deck 2a of the front window 2 by a plurality of brackets 12. That is, when the rotating wiper 6 is located at the lowermost position, the wiper de-eyer 11 is provided at a position parallel to the wiper 6. Further, as shown in FIG. 4, a part of the bent part 11a of the wiper device 11 is bent upward in a bridge shape so as not to interfere with the wiper pivot part 6a of the two wiper arms 6b. Two relief portions 11b are provided. The size of the relief portion 11b is about 150 mm. Further, the total width L of the wiper device 11 is set so as to match the width of the front window 2 of the standard vehicle class, and the wiper device 11 is provided in contact with the front window 2.

Further, the tubes 13 connected to the deck heater provided in the engine room are connected to both ends of the wiper deicer 11 so that the hot water heated by the deck heater circulates in the wiper deicer 11. Has become.

Therefore, when the snow adhering to the front window 2 is scraped off by the wiper 6, the snow is collected at the lower end portion of the front window 2. The snow collected at the lower end of the front window 2 is melted by the heat of the wiper deiser 11, and the snow melted water is drained from the drain hole of the deck 2a.

According to the wiper de-icer device configured as described above, since the wiper de-icer 11 is a flexible pipe that has a circular cross section and is bent in a meandering shape, it can be freely expanded and contracted and bent. Therefore, when it is mounted on the vehicle body, it can be easily bent by hand according to the shape of the front window 2, and can be mounted on the front window 2 of many vehicle types.

[0014]

[Effect of device]

 Since the present invention is configured as described above, the wiper de-facer can be easily bent by hand when it is assembled to the vehicle body, and it can be adapted to various front wind shapes with different curvatures and widths. The effect that it can be shared is obtained.
