Technical field
The present invention relates to the Defrost method of vehicle air conditioner, its green phase improves airshed to previous step to be removed attached to the frost on the Windshield fast up to the wind-force maxim, so that chaufeur can safe driving.
Background technology
Usually, because the inside and outside temperature difference of vehicle, thereby frost can be attached to hindering the forward visibility of chaufeur on the Windshield and may causing accident.When frost attached to Windshield on the time, the defrost button that chaufeur is pressed on the vehicle heater control panel defrosts to change the direction that blows to the wind of Windshield from temperature booster.
Depend on the position of airshed button based on the airshed of defrost button operation,, can not remove frost on the Windshield even press defrost button if the position of airshed button is in lower work gear.
When vehicle ' is on the hill path of express highway, hillside or complications, if arien deposit can not be removed on Windshield as early as possible, just may have an accident, therefore need take some countermeasures.
Summary of the invention
The present invention attempts to provide the Defrost method of the vehicle air conditioner of the advantage with the frost on the quick removal Windshield, so that driver safety is driven.
An exemplary embodiments of the present invention has proposed a kind of defrosting equipment that is used for vehicle air conditioner, it comprises: controller, thereby moisture that its operation signal at high speed that receives the defrosting mode button is removed windshield guarantees to have a forward visibility, and according to the control step output voltage signal to the blower motor of operator's compartment effect; Rating unit, it has circuit to be connected the voltage signal of the blower motor of exporting with the reception controller with controller, and the output voltage of the voltage of more present blower motor and predefined blower motor, the voltage of blower motor can be enhanced the output voltage of predefined blower motor like this; Amplifier, it has circuit to be connected the signal of exporting with the reception rating unit 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 enhanced 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: the operation defrost button is to remove the frost attached to the vehicle windscreen inboard; Detect whether defrost button is pressed and the state of air-conditioning, and the relative previous step of the voltage of the blower motor of drying to Windshield is improved up to maximum voltage.
In the process that blower motor voltage rises, the voltage that is applied to blower motor can improve with the speed of per second 1V.

The specific embodiment
Describe an exemplary embodiments of the present invention below with reference to the accompanying drawings 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 as the blower motor of the defrosting equipment of the described vehicle air conditioner of exemplary embodiments of the present invention, Fig. 3 has shown change of voltage and the control method thereof as the blower motor of the defrosting equipment of the described vehicle air conditioner of exemplary embodiments of the present invention, and Fig. 4 is workflow diagram and the control method thereof as the defrosting equipment of the described vehicle air conditioner of exemplary embodiments of the present invention.
With reference to figure 1 and Fig. 2, defrosting equipment as the described vehicle air conditioner of the present invention's one exemplary embodiments comprises: controller 100, thereby moisture that its operation signal at high speed that receives the defrosting mode button is removed windshield guarantees to have a forward visibility, and according to the control step output voltage signal to the blower motor of operator's compartment effect; Rating unit 200, it has circuit to be connected the voltage signal of the blower motor of exporting with reception controller 100 with controller 100, and the output voltage of the voltage of more present blower motor and predefined blower motor, the voltage of blower motor can be enhanced the output voltage of predefined blower motor like this; And amplifier 300, it has circuit to be connected the signal of exporting with reception rating unit 200 with blower motor, thereby improves the output voltage that is applied to blower motor.
As the control method of the defrosting equipment of the described a kind of control vehicle a/c system of the present invention's one exemplary embodiments, it comprises: step ST100, and its operation defrost button is to remove the frost attached to the vehicle windscreen inboard; Step ST200, it detects the state of air-conditioning and detects inner air and outer air simultaneously by the operation defrost button, and the relative previous step of the voltage of the blower motor of drying to Windshield is improved up to maximum voltage.
The relative previous step of the voltage of blower motor is improved the voltage that is configured to improve with the speed of per second 1V blower motor up to the step ST100 of maximum voltage.
Disclose mode of operation and control method thereof below with reference to the accompanying drawings as the defrosting equipment of the described vehicle air conditioner of the present invention's one exemplary embodiments.
Referring to figs. 1 to Fig. 4, when steering vehicle, chaufeur is pressed the defrost button 2a with mode switch 2, to remove the frost attached to windshield.If defrost button 2a is pressed, corresponding signal is imported into controller 100, and the output voltage V i (not shown) of the corresponding blower motor of the control step of blower motor at present is imported into rating unit 200 by the calculating section of controller 100.
Simultaneously, the control part (not shown) that is installed on the vehicle detects whether air-conditioning is opened and whether is transferred to exterior air patterns in step ST10.If air-conditioning is in the state of pass, the operate compressor (not shown) is to open air-conditioning, if air-conditioning is in the inner air pattern, this pattern is forced to be transformed into the exterior air patterns of step ST30.
After air-conditioning quilt was transformed into exterior air patterns, rating unit 200 improved the relative previous step of the voltage of the blower motor 10 of drying to Windshield up to maximum voltage at step ST200.
Promptly, 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 to the permission voltage of blower motor 10 at present, if allow voltage to be lower than the output voltage of predefined blower motor 10, then rating unit 200 is to amplifier 300 output signals, thereby improves the voltage that is applied on the blower motor with the speed of per second 1V.
The output voltage V o of blower motor 10 is by amplifier 300 outputs, and output voltage V m is applied on the blower motor 10.Therefore, this voltage that is enhanced is higher than frost voltage before, thus the fan (not shown) high-speed cruising of blower motor 10, cooled air blows to Windshield with the state that is converted into exterior air patterns in the air-conditioning, and therefore frost is removed fast.
After frost is removed fully, if the user has turned off defrost button 2a, corresponding signal is imported into controller 100, so that signal no longer is transferred to rating unit 200, so the airshed that blows out of blower motor 10 remains on the airshed before defrost button 2a closes.
If user selection is pressed defrost button 2a, select automatic mode or manual regulation airshed, then the voltage of blower motor 10 raises and is cancelled.
Though 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, it will contain the various modifications and the equivalent that spirit and scope comprised of claim.
As mentioned above, but be used for the defrosting equipment of vehicle air conditioner as described in the present invention and the control method at high speed is removed attached to the frost on the Windshield, so that chaufeur can safe driving.
