Thereby, the temperature of the interior of the car is always kept comfortable in accordance with the "set interior temperature ".

On the other hand, the air conditioner further includes a sunroof 18 in recent years.

The sunroof 18 is formed by forming an opening (not shown) on the roof of the vehicle and opening / closing the opening with a sunroof glass (not shown) so that when the user presses the sunroof switch 6 of the controller 1, The sunroof 18 is operated to open the opening of the vehicle roof. Therefore, sunlight, wind, etc. are introduced into the interior of the vehicle through the opened opening.

However, in such a conventional air conditioner, when the sunroof 18 is opened, a large amount of wind is introduced into the car interior through the open sunroof 18, The rotation speed of the blower 9 is controlled to be constant regardless of whether the sunroof 18 is open or closed.

In addition, there is a drawback that unnecessary energy is consumed because of such a disadvantage, and the fuel economy of the vehicle is increased due to such a problem.

In addition, in the conventional air conditioner, when the sunroof 18 is opened, a passenger in the passenger compartment receives a feeling of sudden increase in air volume due to the wind introduced into the sunroof 18, The number of rotations of the blower 9 is lowered in order to compensate for this.

In order to solve this problem, there is a problem in that the number of rotations of the blower 9 must be lowered every time the sunroof 18 is opened. This is a drawback that it is very troublesome and inconvenient to use because of such a problem.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a vehicle air conditioner capable of actively controlling the rotational speed of a blower in accordance with the control of a sunroof.

It is another object of the present invention to provide a blower control apparatus and method that can actively control the rotational speed of a blower in accordance with control of a sunroof so as to prevent an excessive control of the rotational speed of the blower despite the introduction of wind through the sunroof And an air conditioner for a vehicle.

It is a further object of the present invention to provide a blower which is capable of preventing unnecessary control of the rotational speed of the blower despite the introduction of wind through the sunroof, thereby preventing unnecessary energy consumption, And to provide a vehicle air conditioner that can be expected.

It is still another object of the present invention to provide a blower control apparatus and a blower control method for controlling the rotation speed of a blower in accordance with a control of a sunroof in order to compensate for an increase in airflow introduced through a sunroof And the air conditioning apparatus does not need to reduce the number of steps individually.

It is still another object of the present invention to provide a vehicle air conditioner which can improve convenience for a user because it is not necessary to lower the number of revolutions of the blower when the sunroof is opened.

In order to achieve the above object, a vehicle air conditioning system according to the present invention comprises: a blower for sucking in and outside air to blow air into a passenger compartment; and a blower for blowing sunlight and wind A vehicle air conditioning system including a sunroof which allows indoor introduction of a vehicle, characterized in that the rotational speed of the blower is controlled in a differential manner according to whether the sunroof is operated, And a control unit for differentially controlling the operation according to the operation state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a vehicle air conditioner according to the present invention will be described in detail with reference to the accompanying drawings (the same components as those in the prior art are denoted by the same reference numerals).

First, an air conditioning apparatus will be briefly described with reference to FIG. 2 before a characteristic portion of a vehicle air conditioner according to the present invention will be described.

The air conditioner can be set by selecting the "Auto mode" with the auto mode switch 3 of the controller 1 and then setting the desired "car room temperature" with the temperature control switch 5, The temperature data of the inside and outside of the car sensed by the sensor are compared and processed to calculate optimum data.

And controls the intake door 7, the blower 9, the evaporator 10, the heater 12, the tempo door 14, and the various mode doors 16 based on the calculated data.

Therefore, the temperature and air volume of the air supplied to the passenger compartment, the discharging mode, the inside / outside air mode, and the like are automatically adjusted according to the temperature conditions outside the passenger compartment and the preset passenger compartment temperature. Thereby, the temperature of the interior of the car is always kept comfortable in accordance with the "set interior temperature ".

The air conditioning apparatus further includes a sunroof (18). The sunroof 18 is provided with an opening (not shown) on the roof of the vehicle and opens and closes the opening with a sunroof glass (not shown).

The sunroof 18 opens the opening of the vehicle roof while the sunroof 18 is operated when the user operates the sunroof switch 6 of the controller 1 to turn on. Therefore, sunlight, wind, etc. are introduced into the interior of the vehicle through the opened opening.

Next, the features of the air conditioner for a vehicle according to the present invention will be described in detail with reference to FIG. 2 and FIG.

Referring to FIG. 2, the air conditioning system of the present invention includes a sunroof detection means 20 for detecting whether or not the sunroof 18 is operated.

The sunroof detecting means (20) is constituted by a sunroof switch (6) provided in the controller (1).

The sunroof switch 6 is for allowing the user to turn on or off the sunroof 18. When the user pushes the sunroof switch 6, the sunroof switch 6 outputs a "sunroof on signal" When it is turned off (OFF), a "sunroof off signal" is outputted. Thus, by outputting the "sunroof on signal" or "sunroof off signal ", it is possible to detect whether the sunroof 18 is on or off.

The air conditioner of the present invention comprises a control unit (30).

The control unit 30 is equipped with a microprocessor. When the "sunroof on signal" is inputted from the sunroof detecting means 20, the current sunroof 18 is in operation and the operation sunroof 18 is operating, It is determined that the wind is introduced into the passenger compartment through the sunroof 18.

It is determined that it is necessary to reduce the rotational speed of the blower 9 according to the determination. In this case, the control unit 30 enters the "blower blowing amount reduction mode".

The control unit 30, which has entered the "blower air blowing amount reduction mode", reduces the number of rotations of the blower 9 by a predetermined number of rotations, for example, "one step" lower than the current number of rotations.

Therefore, the air volume of the blower 9 introduced into the passenger compartment is reduced. Thereby, it is possible to prevent the blower 9 from being rotated excessively even though a large amount of wind is introduced into the passenger compartment through the sunroof 18. As a result, unnecessary energy consumption can be prevented, and the effect of reducing fuel consumption can be expected.

In addition, since the rotational speed of the blower 9 is actively reduced in accordance with the opening of the sunroof 18, it is possible to compensate for the increase in the amount of air flowing through the sunroof 18 when the sunroof 18 is opened So that the user does not have to manually lower the number of rotations of the blower 9. This improves the convenience of the user.

On the other hand, when the sunroof 18 is opened, the control unit 30 actively reduces the rotational speed of the blower 9, but decreases the rotational speed of the blower 9 according to the traveling speed of the vehicle inputted from the vehicle speed detecting means 40 do.

That is, even if the "sunroof on" signal is inputted from the sunroof detecting means 20, the control unit 30 determines whether the traveling speed of the vehicle inputted from the vehicle speed detecting means 40 is equal to or higher than the predetermined "first vehicle speed" , It is configured to decrease the rotational speed of the blower 9 while entering the "blower blowing amount reduction mode" only when it is 30 km / h or more.

This is because even if the sunroof 18 is opened, the amount of wind introduced into the passenger compartment through the sunroof 18 is not large when the running speed of the vehicle is less than 30 km / h. Therefore, when the running speed of the vehicle is less than 30 km / h, it is not necessary to reduce the blowing amount of the blower 9.

2, when the "sunroof off signal" is inputted from the sunroof detecting means 20 in a state in which the control unit 30 enters the "blower air blowing amount reduction mode" 18 is turned off, it is determined that the wind flowing through the sunroof 18 is erased.

In this case, the controller 30 resets the rotational speed of the blower 9 to its original state while being released from the "blower blowing amount reduction mode". Therefore, the air blowing amount of the blower 9 can be restored normally.

On the other hand, when the sunroof 18 is not turned off while the vehicle enters the "blower air blowing amount reduction mode", the control unit 30 determines whether the traveling speed of the vehicle inputted from the vehicle speed detecting means 40 is " Quot; second vehicle speed ", for example, 20 km / h or less, it is restored from the "blower blowing amount reduction mode ", and the rotational speed of the blower 9 is returned to the original state.

This is because, when the traveling speed of the vehicle is 20 km / h or less, the amount of air to be introduced through the sunroof 18 is very small, so that it is not necessary to reduce the blowing amount of the blower 9.

Next, an operation example of the present invention having such a configuration will be described with reference to Figs. 2 and 3. Fig.

First, in a state that the air conditioner is turned on (S101), it is determined whether the sunroof 18 is turned on (S103).

As a result of the determination, if the sunroof 18 is turned ON, the control unit 30 determines again whether the running speed of the vehicle is equal to or greater than a predetermined "first vehicle speed", for example, 30 km / h (S015 ).

As a result of the judgment, when the speed is 30 km / h or more, the control unit 30 needs to reduce the rotational speed of the blower 9 to compensate for a large amount of wind flowing into the car through the sunroof 18 , And enters the "blower blowing amount reduction mode" in accordance with this recognition (S107).

Then, the control unit 30 that has entered the "blower blowing amount reduction mode" reduces the blower 9 by a predetermined number of steps, for example, "one step" (S109).

Then, the air volume of the blower 9 introduced into the passenger compartment is reduced. Thereby, the rotational speed of the blower 9 is actively reduced in accordance with the increase in the amount of air introduced through the sunroof 18.

On the other hand, in a state in which the number of rotations of the blower 9 is reduced, the control unit 30 again determines whether the sunroof 18 is turned off (S111).

As a result of the determination, when the sunroof 18 is turned off, the control unit 30 recognizes that the wind flowing through the sunroof 18 is erased (erased) Quot; (S113).

Then, the control section 30 released from the "blower blowing amount reduction mode" returns the rotation speed of the blower 9 to the original state (S115). Then, the blowing amount of the blower 9 is restored normally.

On the other hand, if it is determined in step S111 that the sunroof 18 has not been turned off (S111-1), the control unit 30 determines again whether the running speed of the vehicle is equal to or less than a preset "second vehicle speed" ). For example, 20 km / h or less.

As a result of the determination, if the speed is 20 km / h or less, the control unit 30 recognizes that the wind is currently flowing through the sunroof 18, but the inflow amount thereof is very small and it is necessary to restore the rotation speed of the blower 9 , And is released from the "blower blowing amount reduction mode" in accordance with this recognition (S113).

The control unit 30 released from the "blower blowing amount reduction mode " returns the rotation speed of the blower 9 to the original state (S115). Then, the blowing amount of the blower 9 is restored normally.

According to the air conditioner of the present invention having such a configuration, when the sunroof 18 is opened, the rotation speed of the blower 9 is actively reduced accordingly, so that the introduction of wind through the sunroof 18 It is possible to prevent the rotational speed of the blower 9 from being excessively controlled.

Further, it is possible to prevent excessive control of the rotational speed of the blower 9 in spite of the introduction of wind through the sunroof 18, so that unnecessary energy consumption can be prevented, You can expect.

Since the rotational speed of the blower 9 can be actively controlled in accordance with the opening of the sunroof 18, it is possible to compensate for the increase in the amount of air flowing through the sunroof 18 when the sunroof 18 is opened The user does not need to lower the number of rotations of the blower 9 manually.

In addition, when the sunroof 18 is opened, the number of rotations of the blower 9 is not required to be manually lowered, thereby improving convenience for the user.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
