Abstract

The utility model relates to an infrared defroster for the front windshield of an automobile. Due to the fact that warm air is adopted for removing frost in the prior art, the problems of low heating temperature, little frost removing area and bad frost removing effect are produced; the problems are overcome by the infrared defroster for the front windshield glass of the automobile. The infrared defroster for the front windshield glass of the automobile is characterized in that the generator of the automobile is used as the power supply; a far infrared heater is used to proceed with frost removing, which means that a binding post is installed on both ends of a quartz tube in which a resistance wire is installed; the power supply is connected, via a conducting wire; a reflecting cover is installed on one side of the quartz tube, and is aligned with the front windshield. The utility model has the advantages of simple structure, high reliability, high speed, high surface temperature, big frost removing area and good frost removing effect.

Description

Infrared defroster for front windshielf glass of automobile

The utility model belongs to a kind of washing equipment of vehicle windscreen, the infrared defogger of particularly a kind of windshield glass of automobile.

In the prior art to the defrosting of windshield glass of automobile, particularly to the defrosting of the front windshield glass of motor omnibus, generally take the warm braw defrosting, but because heating-up temperature is low, the defrosting area is little, thereby defrosting effect is bad, add the apparatus structure more complicated of warm braw defrosting, also break down easily, the effect of out of reach defrosting, the driver does not usually use yet, directly with artificial defrosting.Adopt two-layer front windshield glass at northern some places, make frost-free on glass, but this method poor transparency, influence driver's sight line, cause train operation accident easily.

The purpose of this utility model is to solve weak point of the prior art, a kind of surface temperature height is provided, the defrosting area is big, the defogger that defrosting speed is fast, make it that frost of whole front windshield glass all is removed, guarantee the diaphaneity of front windshield glass, thereby guarantee traffic safety.

The utility model is as power supply with automobile current generator, utilize far infrared heater to defrost, promptly binding post is installed at the quartz tube two ends of interior dress resistor wire, connect the automobile current generator power output end by lead, in quartz tube one side a reflection shield is installed, is made it aim at front windshield glass, after the energising, its surface temperature can reach more than 300 ℃, can rapidly the frost of front windshield glass be removed.

Provide embodiment of the present utility model below in conjunction with accompanying drawing:

Accompanying drawing 1 is a front view of the present utility model; Accompanying drawing 2 is left views of the present utility model.

As shown in drawings, it is 10 to 14 millimeters quartz tube 2 that the utility model has an internal diameter, at the two ends of quartz tube 2 magnetic head 1 is housed, between magnetic head 1 and the quartz tube 2 with asbest paper and silica flour add that adhesives is in addition bonding, sealing with fix; In the middle of the end cap of said magnetic head 1, have a through hole, a binding post 4 is installed in this through hole; An electric cocainine 3 of being made up of the nichrome wire of 0.3-0.4 millimeter spirals in the middle of said quartz tube 2, the two ends of said resistor wire 3 are riveted on respectively in the half knob screw intermediate groove of binding post 4, on the screw rod of the outer end of binding post 4, be separately installed with the nut 5 and the nut 7 of a pair of mutual locking, a pair of pad 6 is installed between nut 5 and nut 7, lead 16, one ends be live wire (+) in clamping between a pair of pad 6; One end is a zero line (-), and wherein the live wire end inserts automobile current generator power output end (voltage is 12 volts or 24 volts) by switch 18.Anchor clamps 11 are installed outside the magnetic head 1 at said quartz tube 2 two ends, anchor clamps 11 1 ends are locked with spring cotter 13, the other end is fixed on the reflection shield 12 by bolt 8, nut 9 and spring chair 10, and said reflection shield 12 is a semicircle type, and its opening direction is aimed at windshield glass of automobile; The lower end of reflection shield 12 is riveted on the support 17 by rivet 14, and support 17 is fixed on above the gauge panel of automobile cab by screw 15 again.During use, with car engine, automobile current generator promptly produces direct current (DC), opens switch 18, and power supply can pass on the resistor wire 3 by lead 16 and binding post 4, produces infrared radiation by quartz tube, plays heating defrosting effect.

The utility model has the advantage of simple in structure, use reliably owing to adopt the principle of Far-infrared Heating to defrost, thereby the surface temperature height, the defrosting area is big, defrosting speed is fast, defrosting effect is good.
