A car wiper defrosting device

Abstract

The invention provides a thawing unit for an automobile windscreen wiper, belonging to the technical field of automobiles and solving the problem that the traditional thawing unit for the windscreen wiper leads to uneven heating to a windscreen so as to result in a cracking phenomenon. The thawing unit for the automobile windscreen wiper in the invention comprise an outer wind guiding pipe, a control mechanism 1 capable of controlling the communication state of the outer wind guiding pipe is arranged on the outer wind guiding pipe, one end of the outer wind guiding pipe can be communicated with an air-conditioner wind outlet pipe, the other end of the outer wind guiding pipe is provided with a wind outlet and is located below the outer side of a front windscreen, and when a wiper blade of the windscreen wiper is located at a lowest position, the wiper blade corresponds to the wind outlet of the outer wind guiding pipe. The thawing unit for the automobile windscreen wiper in the invention has the advantages of high thawing efficiency, travel time saving performance, simple structure, low production cost, capability of being used in different vehicle types, high use safety and long service life, and can be used for evaporating thawed water in a thawing process so as to prevent the thawed water from icing at other positions.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to an automobile windshield wiper, in particular to an automobile windshield wiper defrosting device. Background technique [0002] Automobile refers to a vehicle that is driven by its own power plant, generally has four or more wheels, and does not rely on rails or wires to drive on land. In the cold winter, severe weather such as snow and freezing is often encountered, and cars are also one of the most vulnerable items to be affected by severe cold. The front windshield is covered with ice and snow, which makes the car unable to use normally; in order to clear the ice and snow from the front windshield, it is necessary to start the wiper, and use the wiper to remove the ice and snow to both sides. When the front windshield is covered with ice and snow, the wiper blades of the wipers will also be frozen firmly on the front windshield, and the wipers cannot rotate normally. [0...

AI Technical Summary

Problems solved by technology

Although this technical solution has been solved in theory, there are certain defects, that is, if the temperature in the area near the contact surface between the wiper and the front windshield is lower than zero, there will be no rainwater accumulation and no freezing, but the control circuit will still be damaged. To control the heating of the heating body, it will inevitably waste energy and damage the blades of the front windshield and wiper

This solution can easily lead to uneven heating of the windshield and cracks. Moreover, the current air conditioner can achieve the same function. It is installed at the air outlet under the front windshield indoors, and the warm air can be blown directly to the windshield. Glass
