Embodiment Construction

[0021] Please refer to Fig. 1 to Fig. 5, wiper blade defrosting device of the present invention comprises heating body 3, temperature sensor 1 and heating control circuit 2, and this heating control circuit 2 is connected with heating body 3 and temperature sensor 1, and this temperature sensor 1 monitors wiper blade 4 The temperature of the contact surface area with the front windshield 5, and output a temperature signal to the heating control circuit 2, the heating control circuit 2 judges whether the wiper 4 is frozen according to the temperature signal, if it is frozen, then control the heating body 3 to heat and Defrost wiper 4. The heating body 3 is a rectangular wave-shaped heating wire 3 .

[0022] Since the wiper 4 stays on the outer side of the lower edge of the front windshield 5 when it is closed, the electric heating wire 3 is pasted on the inner side of the lower edge of the front windshield 5 corresponding to the position of the wiper 4, and the area of ​​the el...

Abstract

The invention comprises: heating body, temperature sensor and heat control circuit. The heat control circuit is connected to the heating body and the temperature sensor. The temperatures sensor monitors the temperature at the area nearby the windshield contacted with the wipe blade, and sends the temperature signals to the heat control circuit; the heat control circuit determines if the wiper blade is frozen; if yes, then controls the heating body to defreeze the wiper blade.

Description

【Technical field】 [0001] The invention relates to the field of automobile windshield wipers. 【Background technique】 [0002] In the cold winter, because there is often water accumulation on the blade of the wiper, if the wiper does not operate for a period of time or the car is left outside for a period of time, the wiper will often freeze with the windshield of the car. Cause the wiper to fail to start, damage the wiper, and even burn the wiper motor. 【Content of invention】 [0003] The object of the present invention is to provide a device that can quickly unfreeze the wiper blades frozen on the windshield when the wiper blades are started, and an automobile with the device. [0004] The object of the present invention is to provide a method that can quickly unfreeze the wiper blades frozen on the windshield when the wiper blades are started. [0005] The object of the present invention is achieved in that the wiper defrosting device includes a heating body, a temperat...
