Problems solved by technology

However, the alcohol contained in the cleaning solution has a corrosion and swelling effect on the glass sealing rubber, paint surface and wiper blade, which will shorten the life of these parts, so it is not suitable for multiple use.
In addition, when the car is driving at a temperature below 0°C or in snowy weather, frost or icicles will form on the windshield, and the wiper function will be reduced or even unable to start. Driving is very dangerous. Therefore, how to quickly melt the frost or icicles on the windshield is crucial It is also of great significance to improve the safety of vehicle operation
[0003] In the prior art, the car windshield cleaning device generally does not have a heating device, which cannot effectively prevent the non-alcoholic cleaning fluid from freezing and melting the windshield from frost or ice.

Abstract

A heating type windshield glass washing device comprises a washing liquid tank, a washing liquid pump, a washing liquid spraying opening, a windshield glass washing device switch, a heating valve, three three-way valves, a one-way valve, a washing liquid heater, a washing liquid heater water inlet pipe, a washing liquid heater water outlet pipe, a temperature sensor and a controller; two gears arearranged on the windshield glass washing device switch so that washing liquids without alcohol components at a low temperature and a high temperature can be sprayed out; when the temperature is lowerthan 0 degree centigrade, the washing liquid without the alcohol components can be heated by using hot water led to an automobile heating system so as to prevent the washing liquid from being frozen;and the washing liquid at the high temperature can be provided to rapidly melt frost or ice on a windshield glass. The heating type windshield glass washing device has the advantages of simple structure and low cost and can adapt to all automobiles with water-heated air conditioner heating systems.

Description

technical field [0001] The invention belongs to the field of automobile manufacturing, and in particular relates to a heating type windshield cleaning device. Background technique [0002] The cleaning fluid used in the car windshield cleaning device is generally composed of water + alcohol + detergent. The higher the alcohol content, the lower the freezing point and the better the antifreeze, which can prevent the cleaning fluid from freezing during winter use. However, the alcohol contained in the cleaning solution has a corrosion and swelling effect on the glass sealing rubber, paint surface and wiper blade, which will shorten the life of these parts and should not be used more. In addition, when the car is driving at a temperature below 0°C or in snowy weather, frost or icicles will form on the windshield, and the wiper function will be reduced or even unable to start. Driving is very dangerous. Therefore, how to quickly melt the frost or icicles on the windshield is cru...
