Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a dew condensation preventing device for a windshield that eliminates the fog on the lower end of the windshield of an automobile to improve the driver's visibility.

[0002]

[Prior art]

 In order to prevent dew from adhering to the inner surface of the windshield of an automobile, or to evaporate the dew that has adhered, or to melt frost or ice that has adhered to the outer surface of the windshield, as shown in FIG. Warm air is blown out from the defroster nozzle 3 that opens on the upper surface and is sent along the inner surface of the windshield 1.

Further, as disclosed in Japanese Utility Model Laid-Open No. 57-32561 and Japanese Utility Model Laid-Open No. 56-64848, the defroster nozzle is not provided on the entire surface in the width direction of the windshield, and A plurality of defroster nozzles are provided partially for the width of the.

[0004]

[Issues to be solved by the device]

 The warm air blown out from the defroster nozzle 3 hits a portion A above the lowermost end portion of the windshield 1 by a predetermined dimension, and rises along the inner surface of the windshield 1 from there.

Therefore, the warm air from the defroster nozzle 3 is scarcely sent to a portion below the portion A on which the warm air first hits. As a result, the ambient temperature around the lowermost edge B 1 of the windshield 1 remains low, and dew, frost, ice or the like adheres to the lowermost side edge B of the windshield 1 to obstruct the driver's view. There is. This means that in the case where the distance dimension from the above-mentioned portion A to which the warm air hits to the lowermost end of the windshield 1 is large, for example, the conshield type in which the wiper storing space S is formed between the windshield 1 and the hood panel 2. It is especially a problem.

[0006] Although disclosed in Japanese Utility Model Laid-Open Nos. 57-32561 and 56-64848, air is blown out from the lowermost end of the windshield, but the defroster nozzle The blown air does not stay or disperse in the space formed between the windshield and the air flow along the windshield.Therefore, there is no air flow between the defroster nozzles. There is a problem in that some parts go out of reach, and it is not possible to reliably remove the adhesion of dew, frost, ice, etc. on those parts, which obstructs the driver's view.

The present invention has been made in view of this problem, and pays attention to the fact that the dew condensation phenomenon and the frozen ice phenomenon of the windshield occur from the lowermost side edge portion where the surface temperature is low, and the hot air is supplied to the front glass. The position is in the space between the windshield and the installation panel, and the air is distributed between the defroster nozzles to prevent the formation of dew condensation on almost the entire surface of the windshield. It is intended to provide a dew condensation prevention device that does not interfere with the visibility.

[0008]

[Means for Solving the Problems]

 The means of the present invention forms an installation panel by forming a constant space between the lowermost end of the windshield and the windshield, raising it upward, and then bending it substantially horizontally in the direction away from the windshield. However, the installation panel is provided with a defroster nozzle that is close to the lowermost end of the windshield and opens into the space, and the air blown out from the defroster nozzle is accumulated and dispersed in the space to allow the defroster nozzle to move. The feature is that it is oriented toward the space portion.

[0009]

[Action]

 According to the present invention, a fixed space is formed between the lowermost end of the windshield and the windshield, the protrusion is raised, and then the installation panel is formed by bending the windshield substantially horizontally in a direction away from the windshield. The defroster nozzle that is close to the bottom edge of the windshield and that opens into the space is installed in the installation panel, so the space between the windshield and the installation panel is filled by the air supplied from the defroster nozzle. By adjusting the temperature, it becomes possible to prevent dew condensation from occurring on the windshield facing this space.

Even if dew condensation occurs at the lowermost end of the windshield that is not supplied by the air supplied from the defroster nozzle, the dew condensation is generated at the bottom of the space. The dew condensation is blocked by the installation panel and is not visible to the driver, and it is possible to prevent the dew condensation from hindering the driver's view.

Further, since the defroster nozzle is oriented with respect to the space portion in a direction in which the air blown from the defroster nozzle is accumulated and dispersed in the space portion, for example, the defroster nozzle is arranged in the width direction of the windshield. Even if there are multiple units spaced apart from each other, it is possible to spread the air over almost the entire surface of the windshield and prevent the formation of frost or the like that occurs on the windshield over almost the entire surface of the windshield. .

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a windshield of a motor vehicle, 2 is a hood panel, and a space S for storing a wiper (not shown) is provided between these 1 and 2. Reference numeral 3 is a defroster nozzle that blows warm air onto the inner surface of the windshield 1, and the opening of the defroster nozzle is located at the same height as the lowermost end of the windshield 1, and the lower step of the stepped installation panel 4 is located. It is provided on the upper surface of the portion 4a and is arranged at a position as close as possible to the lowermost end of the windshield 1. Further, as is clear from the figure, in the space formed by the windshield 1 and the installation panel 4, this space is horizontally raised in the direction away from the windshield 1 after the installation panel 4 is vertically raised. It is narrow at the bent part.

Therefore, the warm air blown out from the defroster nozzle 3 fills the space formed between the windshield 1 and the installation panel 4 having the stepped portion 4a, and then flows along the inner surface of the windshield 1. While being dispersed over almost the entire widthwise direction of the windshield 1, it rises along the inner surface of the windshield 1 and spreads over the entire widthwise direction of the windshield 1 from the lowermost end of the windshield 1 to the upper portion of the front glass 1. It becomes possible to prevent condensation that occurs. Even if warm air does not hit the lowermost edge of the windshield 1 and condensation occurs on that portion, the condensation is hidden by the installation panel 4, and the condensation prevents the driver's view. There is no such thing.

[0014]

[Effect of device]

 As described above, according to the present invention, a certain space is formed between the lowermost end of the windshield and the windshield, and the space is raised upward and then bent substantially horizontally in the direction away from the windshield. Since an installation panel is formed so that air is supplied to the space portion from the defroster nozzle that is close to the bottom end portion of the front glass and opens in the space portion, the dew condensation that occurs at the bottom end portion of the windshield is formed. In addition, it prevents the driver's view even if dew condensation occurs on the lowermost end of the windshield.

Further, since the defroster nozzle is directed to the space portion in a direction in which the air blown out from the defroster nozzle is accumulated and dispersed in the space portion, for example, the defroster nozzle is arranged in the width direction of the windshield. Even if a plurality of windshields are provided at intervals, air can be dispersed over almost the entire surface of the windshield to prevent the formation of frost or the like on the windshield over almost the entire surface of the windshield.
