Abstract

A defroster that can prevent frost from adhering to a windshield of an automobile in winter. An adsorption board made of a soft resin such as vinyl chloride is made and attached to a windshield or the like. Water vapor in the air no longer exists on the surface of the windshield, preventing the generation of frost. [Selection] Figure 1

Description

  An object of the present invention is to prevent frost from adhering to the windshield surface of an automobile, especially in the winter season.

In the cold season such as winter, frost may be attached to the windshield or the like, particularly when starting to drive an automobile early in the morning. The frost adhering to the window is called window frost. Since the window is made opaque, it is not possible to see the outside if the car is driven, and therefore it is necessary to remove it.
Therefore, it is necessary to remove the frost by wiping the frosted part with a steaming towel, pouring hot water, warming up the car or waiting for the frost to melt, etc. More than that, steamed towels and hot water have problems such as the risk of glass breaking.

The present invention is not a method of how to remove frost attached to a windshield or the like, but a method for preventing frost from being attached to the windshield or the like, in which measures against frost are taken.
In the first place, the attachment of frost on the windshield etc. When the surface temperature of the windshield etc. cools to below 0 ° C, water vapor in the air sublimates (solidifies), and ice with a fine crystal structure on the surface of the windshield etc. Although this crystal, that is, the icing phenomenon is frost, it is called “window frost”. Accordingly, frost does not adhere unless water vapor in the air is present on the surface of the windshield or the like, and the generation of frost is eliminated by taking this method.

As a means for achieving the object of the present invention, which has been tried in view of the above problems, a method using a suction disk attached to a windshield or the like is taken.
An adsorption board was made on the windshield etc. with a soft resin such as vinyl chloride, and it was adsorbed on the windshield etc. According to this method, when the adsorption plate is pushed and released after returning to its original state at a temperature at which frost does not occur, the adsorption plate becomes in a vacuum state and is adsorbed on the windshield etc. There is no intrusion, so window frost does not occur on the windshield.

As a test of the effect of the present invention, when the winter minimum night temperature fell to -3 ° C this winter, a windshield frost generation test was conducted on the windshield of a passenger car with a prototype adsorption plate. The window frost did not occur.
On the other hand, the generation of window frost was observed on the windshield of other passenger cars that were parked in the same place and had no suction cups installed, and the effects of the present invention could be confirmed.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

First, the suction disk 1 is made of a soft resin such as vinyl chloride. The suction disk 1 has a central portion that is raised in a mountain shape, and has a void at the bottom.
On the other hand, there is a handle: 2 at the top of the suction disk: 1 and a claw part: 3 in the middle of the chevron.

  In order to use the “frost protection device” of the present invention, the suction plate 1 is first installed in a place where it is desired to suppress the generation of window frost with a windshield or the like while the outside air temperature is not lowered to 0 ° C. Place the suction disk: 1 in that place, push the handle: 2 with your hand, and then let go.

  If the suction disk cannot be adsorbed in its original shape due to the narrow location or shape of the suction disk, the suction disk can be cut to match the shape.

  When the suction disk is peeled off from the windshield or the like, the nail part 3 may be grasped and peeled off.

  The adhering plate, which is the “frost protection device” of the present invention, is attached to the car, in addition to the windshield: 4, the rear glass: 5, the side glass: 6, and the rearview mirror: 7, but the car driver is driving. All locations that fall within the field of view are target installation locations.

It is a top view of the present invention. It is sectional drawing of this invention. It is a figure of the example of the place which sticks a suction cup when implementing this invention. When implementing this invention, it is a figure of an example which showed the part where the installation place of a suction cup is anticipated to be narrow. FIG. 4 is a diagram in the case where the suction plate is attached to a place such as [FIG. 4], in which the hatched portion of the suction plate [FIG. 1] is cut in accordance with the shape of the place where the suction plate is attached. Rearview mirror: FIG. Also in the case of installing at this place, the suction disk may be cut according to the shape in the same manner as in FIG.

The following fields can be considered as fields that can be utilized in addition to the present invention.
(1) The vehicle can be used not only in automobiles but also in the railroad field including trains, and for home use in residential windows.

Claims (3)

A method to prevent the generation of frost by making an adsorption board made of soft resin such as vinyl chloride and attaching it to the windshield, etc., as frost protection for automobile windshields. A method that allows you to change the shape by cutting the suction cup to match the location where the suction cup is attached. A method of making the suction plate itself a lens and making it opaque so that fires do not occur in the car.
