A method for wiping rain of an automobile comprises the following steps:
preheating a heat exchanger:
starting automobile engine, engine exhaust enters into the lower floor air cavity of heat exchanger from automobile exhaust entry, and automobile exhaust flows to the right side from the lower floor air cavity left side, later from I upflow of blow vent entering middle air cavity, and automobile exhaust flows to the left side from the middle air cavity right side, later upwards flows into upper air cavity from II upflows of blow vent, flows out from the automobile exhaust exit on upper air cavity right side at last, flows into in the vehicle vent pipe through the pipeline at last.
Step two, starting the wiper:
the wiper motor is started, the wiper swings left and right under the driving of the wiper motor, and centrifugal force generated by swinging enables the extension arm of the wiper to overcome the pulling force of the tension spring and extend outwards, so that the effective cleaning area of the wiper is increased. After the extension arm of the windscreen wiper is extended, the roller at the front end of the extension arm of the windscreen wiper can cling to the sealing strips around the windscreen to roll, so that the front end face of the extension arm of the windscreen wiper is prevented from directly contacting the sealing strips around the windscreen to scratch the sealing strips around the windscreen. After the wiper motor is closed, the wiper stops swinging, and the extension arm of the wiper is retracted into the wiper under the action of the tension spring.
Step three, cleaning the surface of the windshield:
and starting the high-pressure water pump, and simultaneously starting the wiper motor. The high-pressure water pump injects the purified water in the water tank into the coiled pipe of the heat exchanger under a certain pressure, the purified water is quickly vaporized after entering the coiled pipe due to the exhaust temperature of an automobile engine being 500-800 ℃, high-pressure steam is formed, the high-pressure steam enters the steam inlet pipe of the cleaning agent box through the floating ball check valve and is ejected from the steam ejection hole, a certain amount of cleaning agent in the cleaning agent box is driven to be vaporized, the temperature of the high-pressure steam is reduced, new mixed steam is formed, the mixed steam is guided by the upper baffle and is discharged from the steam outlet of the cleaning agent box, and then the mixed steam enters the wiper cleaner from the steam inlet on the wiper. After the mixed steam enters the clean steam cavity, the temperature around the bulb rises, so that the bulb acts, the supporting plate is lifted, and the push rod is lifted, so that the conical head leaves the conical nozzle, the conical nozzle is opened, the mixed steam is sprayed out of the conical nozzle, and the surface of the windshield is cleaned. Close high pressure water pump after the washing, the windscreen wiper motor also closes simultaneously, and clean steam intracavity portion temperature reduces, makes the thermal bulb action, reduces the backup pad, and then reduces the push rod for the cone gets into conical nozzle, closes conical nozzle, avoids the inside debris that get into of clean steam intracavity portion.
Step four, freezing prevention of the windscreen wiper:
after the automobile is ignited, the electromagnetic air pump starts to supply power, the electromagnetic valve acts to increase the volume of the air cavity, the air in the compressed air cavity inside the wiper separation device is pumped to the electromagnetic air pump,
a certain negative pressure is formed in the compressed air cavity, the rubber drum membrane is retracted into the compressed air cavity under the action of the external atmospheric pressure, and the windscreen wiper is in contact with the windshield. After the automobile is flamed out, the electromagnetic air pump is powered off, the electromagnetic valve is out of action, the piston moves towards the direction of an exhaust port of the air pump under the pushing of the thrust spring, the volume of the air cavity is reduced, gas is injected into a compressed air cavity inside the windscreen wiper separation device, the internal pressure of the compressed air cavity is larger than the atmospheric pressure, the rubber drum membrane bulges out of the compressed air cavity under the action of pressure difference, the windscreen wiper is isolated from the windscreen, and the situation that the windscreen wiper is frozen on the windscreen due to the fact that the temperature is reduced in winter is avoided.
Preferably, the steam outlet of the floating ball check valve on the floating ball check valve is arranged below the side wall of the steam-liquid mixing cavity or on the lower end face of the steam-liquid mixing cavity.
Preferably, the included angle between the upper baffle in the cleaning agent box and the upper end face of the cleaning agent box is 20-40 degrees.
Preferably, the included angle between the lower baffle in the cleaning agent box and the upper end face of the cleaning agent box is 110-130 degrees.
Compared with the prior art, the invention has the following beneficial effects:
(1) the extension of the extension arm of the windscreen wiper is realized through the centrifugal force generated when the windscreen wiper swings, the cleaning area of the windscreen wiper is enlarged, and the energy consumption is reduced.
(2) The mixed steam containing the cleaning agent is adopted to clean the windshield, the cleaning effect is more remarkable, the consumption of purified water and the cleaning agent is saved, and the vehicle cost is reduced.
(3) The automobile exhaust is adopted to provide a heat source for the heat exchanger, and the utilization rate of energy is improved.
(4) After the automobile is flamed out, the rubber drum membrane can lift the windscreen wiper, so that the phenomenon that the windscreen wiper is easy to freeze with a windshield in winter is avoided, and the service life of the windscreen wiper is prolonged.

after cleaning is finished, the high-pressure water pump (5) is closed, the wiper motor (2) is also closed at the same time, the temperature in the cleaning steam cavity (1e1) is reduced, the bulb (1g) is made to act, the supporting plate (1g2) is lowered, the push rod (1g3) is further lowered, the conical head (1g4) enters the conical nozzle (1e2), the conical nozzle (1e2) is closed, and sundries in the cleaning steam cavity (1e1) are prevented from entering;
step four, freezing prevention of the windscreen wiper:
after the automobile is ignited, the electromagnetic air pump (3) starts to supply power, the electromagnetic valve (3a) acts to increase the volume of the air cavity (3e), the air in the compressed air cavity (1c1) inside the wiper separation device (1c) is pumped into the electromagnetic air pump (3), a certain negative pressure is formed inside the compressed air cavity (1c1), the rubber tympanic membrane (1c2) is retracted into the compressed air cavity (1c1) under the action of the external atmospheric pressure, and the wiper (1) is contacted with the windshield,
after an automobile is shut down, the electromagnetic air pump (3) is powered off, the electromagnetic valve (3a) is out of action, the piston (3d) is pushed by the thrust spring (3c) to move towards the exhaust port (3e2) of the air pump, the volume of the air cavity (3e) is reduced, gas is injected into the compressed air cavity (1c1) in the wiper disengaging device (1c), the internal pressure of the compressed air cavity (1c1) is larger than the atmospheric pressure, the rubber tympanic membrane (1c2) bulges the compressed air cavity (1c1) under the action of differential pressure, the wiper (1) is isolated from a windshield, and the wiper (1) is prevented from being frozen on the windshield due to temperature reduction in winter.
2. A method of wiping a rain strip for an automobile according to claim 1, wherein:
and a floating ball check valve steam outlet (7e) on the floating ball check valve (7) is arranged below the side wall of the vapor-liquid mixing cavity (7f) or on the lower end surface of the vapor-liquid mixing cavity (7 f).
