Conventionally, due to the temperature difference inside and outside vehicle, thereby frost can be attached to the forward visibility of obstruction chaufeur on Windshield and may cause accident.In the time that frost is attached on Windshield, chaufeur is pressed defrost button on vehicle heater control panel and is defrosted to change the direction that blows to the wind of Windshield from temperature booster.
Airshed based on defrost button operation depends on the position of airshed button, if the frost on Windshield, in lower work gear, can not be removed even if press defrost button in the position of airshed button.
In the time that Vehicle Driving Cycle is on the hill path of express highway, hillside or complications, if arien deposit can not be removed as early as possible on Windshield, just may have an accident, therefore need to take some countermeasures.
Summary of the invention
The present invention attempts to provide the Defrost method of the vehicle air conditioner with the white advantage on quick removal Windshield, so that driver safety is driven.
An exemplary embodiments of the present invention has proposed a kind of defrosting equipment for vehicle air conditioner, it comprises: controller, thereby its operation signal that receives defrosting mode button ensures a forward visibility to remove fast the moisture of windshield, and according to the control step output voltage signal of the blower motor to operator's compartment effect; Rating unit, it has circuit to be connected the voltage signal of the blower motor that receives controller output with controller, and the voltage of more current blower motor and the output voltage of predefined blower motor, the voltage of blower motor can be raised to the output voltage of predefined blower motor like this; Amplifier, it has circuit to be connected to receive the signal of rating unit output with blower motor, thereby improves the output voltage that is applied to blower motor.
Rating unit can apply output signal so that the output voltage of blower motor can be raised to 9.0V to amplifier.
An exemplary embodiments of the present invention has proposed a kind of Defrost method of vehicle air conditioner, and it comprises: operation defrost button is to remove the frost that is attached to vehicle windscreen inner side; Detect whether defrost button is pressed and the state of air-conditioning, and the relative previous step of voltage of the blower motor to Windshield blowing is improved until maximum voltage.
In the process rising at blower motor voltage, the voltage that is applied to blower motor can improve with the speed of 1V per second.

The specific embodiment
Describe below with reference to the accompanying drawings an exemplary embodiments of the present invention in detail.
Fig. 1 has shown the switch of the vehicle air conditioner of traditional approach, Fig. 2 has shown driving circuit and the control method thereof of the blower motor of the defrosting equipment of the vehicle air conditioner as described in exemplary embodiments of the present invention, Fig. 3 has shown change of voltage and the control method thereof of the blower motor of the defrosting equipment of the vehicle air conditioner as described in exemplary embodiments of the present invention, and Fig. 4 is workflow diagram and the control method thereof of the defrosting equipment of the vehicle air conditioner as described in exemplary embodiments of the present invention.
With reference to figure 1 and Fig. 2, the defrosting equipment of the vehicle air conditioner as described in the present invention's one exemplary embodiments comprises: controller 100, thereby its operation signal that receives defrosting mode button ensures a forward visibility to remove fast the moisture of windshield, and according to the control step output voltage signal of the blower motor to operator's compartment effect; Rating unit 200, it has circuit to be connected to receive the voltage signal of the blower motor that controller 100 exports with controller 100, and the voltage of more current blower motor and the output voltage of predefined blower motor, the voltage of blower motor can be raised to the output voltage of predefined blower motor like this; And amplifier 300, it has circuit to be connected to receive the signal that rating unit 200 is exported with blower motor, thereby improves the output voltage that is applied to blower motor.
The control method of a kind of defrosting equipment of controlling vehicle air conditioner as described in the present invention's one exemplary embodiments, it comprises: step ST100, its operation defrost button is to remove the frost that is attached to vehicle windscreen inner side; Step ST200, it detects the state of air-conditioning and detects inner air and outer air by operation defrost button simultaneously, and the relative previous step of voltage of the blower motor to Windshield blowing is improved until maximum voltage.
Relative the voltage of blower motor previous step is improved until the step ST100 of maximum voltage is configured to improve with the speed of 1V per second the voltage of blower motor.
Disclose below with reference to the accompanying drawings mode of operation and the control method thereof of the defrosting equipment of the vehicle air conditioner as described in the present invention's one exemplary embodiments.
Referring to figs. 1 to Fig. 4, in the time of steering vehicle, chaufeur is pressed the defrost button 2a with mode switch 2, to remove the frost that is attached to windshield.If defrost button 2a is pressed, corresponding signal is imported into controller 100, and the corresponding output voltage V i (not shown) of the blower motor of the control step of blower motor is at present imported into rating unit 200 by the calculating section of controller 100.
Whether the control part (not shown) detection air-conditioning in step ST10 meanwhile, being arranged on vehicle is opened and whether is converted to exterior air patterns.If the state of air-conditioning in closing, operate compressor (not shown) to be to open air-conditioning, if air-conditioning in inner air pattern, this pattern is forced to be transformed into the exterior air patterns of step ST30.
Air-conditioning quilt is transformed into after exterior air patterns, and rating unit 200 improves the relative previous step of voltage of the blower motor 10 to Windshield blowing until maximum voltage at step ST200.
; the comparator comparison of rating unit 200 is according to the output voltage of the predefined blower motor 10 of planning data and be applied at present the permission voltage of blower motor 10; if allow the output voltage of voltage lower than predefined blower motor 10; rating unit 200 is to amplifier 300 output signals, thereby improves with the speed of 1V per second the voltage being applied in blower motor.
The output voltage V o of blower motor 10 exports by amplifier 300, and output voltage V m is applied in blower motor 10.Therefore, this voltage being enhanced is higher than there being frost voltage before, thereby the fan (not shown) high-speed cruising of blower motor 10, in air-conditioning, cooled air blows to Windshield with the state that is converted into exterior air patterns, and therefore frost is removed fast.
After frost is completely removed, if user has turned off defrost button 2a, corresponding signal is imported into controller 100, so that signal is no longer transferred to rating unit 200, the airshed that therefore blower motor 10 blows out remains on defrost button 2a and closes front airshed.
If user's selectivity is pressed defrost button 2a, select automatic mode or manual regulation airshed, the voltage of blower motor 10 raises and is cancelled.
Although in conjunction with thinking that at present practical exemplary embodiments described the present invention, should be appreciated that the present invention is not limited only to revealed embodiment, on the contrary, various modifications and equivalent that it comprises the spirit and scope that contain claim.
As mentioned above, can remove fast for defrosting equipment and the control method thereof of vehicle air conditioner the frost being attached on Windshield as described in the present invention, so that chaufeur can safe driving.
