In addition, the fragrance supplying device 10 has a first opening of the cartridge 16 according to the magnitude of the cumulative air conditioning operating time Tacc calculated by calculating the air conditioning operation time of the fragrance supplying device 10. And a control unit 20 for transmitting a control signal to the actuator 14 so as to adjust the open area set value a in which the 15 and the second opening 13 of the housing 12 overlap each other.

One side of the housing 12, the second opening 13 is provided. The second opening 13 includes an intake port through which the outside air forcedly blown through the blower unit of the air conditioning apparatus 1 enters, and a discharge port for discharging the fragrance 18 to the other side. .

The actuator 14 provides a rotational force to the cartridge 16 to vary the rotation angle according to the control signal of the control unit 20.

The cartridge 16 has a first opening 15 at one side thereof, and opens and closes the second opening 13 of the housing 12 while being rotated forward and backward by the rotational force transmitted from the actuator 14. As a result, the air freshener 18 enters the air conditioner 1 through the discharge port of the second opening 13 together with the outside air introduced through the inlet port of the second opening 13.

The perfume 18 is provided inside the cartridge 16. Of course, the fragrance 18 is provided to be replaceable.

The control unit 20 is a set value of the open area between the first opening 15 of the cartridge 16 and the second opening 13 of the housing 12 according to the operating time of the perfume supply device 10. (a) is adjusted to control the rotation angle of the actuator 14 to maintain a uniform fragrance sensitivity.

Looking at the operating state of the perfume supply device configured as described above are as follows.

First, the perfume 18 is inserted into the cartridge 16.

Subsequently, the cartridge 16 is inserted into the housing 12 so that one end of the cartridge 16 is fixed to the actuator 14. In this case, the first opening 15 of the cartridge 16 is provided at a position where the second opening 13 of the housing 12 is not opened.

Then, when the operation signal of the direction air conditioning is transmitted to the control unit 20, the control unit 20 transmits a control signal to the actuator (14).

In addition, the actuator 14 generates a rotational force to rotate the cartridge 16 at an angle. Accordingly, the first opening 15 of the cartridge 16 opens the second opening 13 as the second opening 13 overlaps the second opening 13 of the housing 12.

Accordingly, the air generated in the air blowing unit of the air conditioning apparatus 1 is sucked through the inlet port of the second opening 13 of the housing 12 and is discharged to the outlet of the second opening 13 on the other side, and the cartridge ( The fragrance 18 provided in 16 is smelled.

On the other hand, the opening area setting value a of the first opening 15 of the cartridge 16 and the second opening 13 of the housing 12 is varied according to the size of the direction air conditioning operation time.

That is, as shown in FIG. 3, the fragrance supply device 10 may be configured by the control signal of the control unit 20 according to the cumulative operation time Tacc accumulated as the air conditioning operation time increases. By increasing the overlapping open area set value a of the second openings 15 and 13, it is possible to maintain a uniform fragrance sensitivity of the perfume.

≪ Embodiment 2 >

The same reference numerals are used for the same components as those in the first embodiment, and detailed description thereof will be omitted.

The perfume supply device 10 according to the second embodiment includes a housing 12 having a second opening 13 including an inlet port and an outlet port, and an actuator provided at one side of the housing 12 to generate rotational force. 14, a cartridge 16 which is provided inside the housing 12 and rotates at an angle by the rotational force generated by the actuator 14, and has a first opening 15 on one side, and the cartridge 16 When the first and second openings (15, 13) are provided on the inside of the fragrance 18, which is swept when the first and second openings (15) (13) are opened by overlapping each other, and the direction air conditioning operation signal is input thereto, the actuator 14 controls accordingly. The control unit 20 transmits a signal to control the first and second openings 15 and 13 to overlap each other as the cartridge 16 is rotated relative to the housing 12.

In addition, the control unit 20 and the first opening 15 of the cartridge 16 in accordance with the direction air conditioning cumulative operation time (Tacc) calculated by accumulating the direction air conditioning operation time when the direction air conditioning operation signal is transmitted; The overlapping open area set value a of the second opening 13 of the housing 12 is controlled to be varied.

That is, as shown in FIG. 6, the control unit 20 may set a superimposed open area setting value a of the first opening 15 of the cartridge 16 and the second opening 13 of the housing 12. ) Is 20%, it is maintained for the T1 reference time of the accumulated operation time (Tacc), and when the T1 reference time is exceeded, the set open area (a) is increased to 40% and T2 of the accumulated operation time (Tacc) If it is maintained for a reference time, and exceeds this again, it controls to increase the said open area set value (a) to the next open area set value (a), and to maintain it for the reference time accordingly.

The reference time values T1, T2, T3, T4, and T5 of the cumulative operation time Tacc are determined according to the displacement amounts 20, 40, 60, 80, and 100% of the open area set value a. According to the displacement amount of the open area set value (a), it is time to maintain a uniform fragrance sensitivity of the perfume.

Looking at the direction air conditioning control method according to the vehicle direction air conditioning device configured as described above are as follows.

First, as shown in Figure 5, it is a step of determining whether the air conditioning is operating (S1).

This determines whether the occupant has selected the operation of the air freshener supply device for the air conditioning of the vehicle, and is determined by the signal of the control unit provided in the vehicle.

If the air conditioning is operating, the second opening of the housing is opened in the same manner as the open area set value of the air freshener supply device stored in the controller (S2).

This is the same as the open area set value (a) of the fragrance supply apparatus stored in the control unit 20, the control unit 20 transmits a control signal to the actuator 14 to the cartridge 16 to the housing 12 The first and second openings 15 and 13 overlap by relative rotation.

That is, as shown in FIG. 4, the open area set value a is sequentially increased in accordance with the cumulative operation time Tacc of the operation time of the perfume supply device.

For example, the open area set value (a) is divided into five stages and configured to increase by 20%.

As shown in FIG. 4A, since the first opening area set value a is in a state in which the fragrance 18 is filled, the overlapping area of the first and second openings 15 and 13 is 20%.

In addition, as shown in Figures 4b to 4e, since the perfume is consumed according to the cumulative operation time (Tacc), the amount of displacement of the open area set value (a) is increased to maintain a uniform perfume sensitivity. That is, the second to fifth open area setting values which increase by 20% in the open area set value (a) are 40, 60, 80, and 100% sequentially.

When the housing second opening is opened in the same manner as the open area set value of the perfume supply device stored in the control unit, the opening time of the opened open area set value is counted (S3).

This overlaps the second opening 13 of the housing 12 and the first opening 15 of the cartridge 16 in the same manner as the final opening area set value (a) of the omnidirectional air conditioning operation stored in the controller 20. If the open area set value a matches, the control unit 20 counts the open time to calculate the cumulative operation time Tacc of the direction air conditioning operation time.

In operation S4, it is determined whether the accumulated accumulated operation time of the controller coincides with the reference time of the current open area setting value.

 As shown in FIG. 6, the open area set value (a) is defined by the first to fifth open area set values (a) according to the size of the open area, and each step of the open area set value (a) is determined. Since the reference time of the opening time is determined, it is determined whether the counting time of the control unit 20 coincides with the reference time of the earth leakage operation time Tacc set in the step-by-step opening area set value a.

That is, the first open area set value (a) having an open area of 20% is the cumulative operating time (Tacc) reference time of T1, and the second open area set value (a) of 40% is the cumulative operating time (Tacc) of T2. The reference time, the third open area set value (a) of 60% is the leakage current operation time (Tacc) reference time of T3, the fourth open area set value (a) of 80% is the cumulative operation time (Tacc) reference time of T4 , The fifth open area set value (a) of 100% is defined as the cumulative operating time (Tacc) reference time of T5.

Accordingly, it is determined whether the time counted by the controller 20 coincides with the reference time of the cumulative operation time Tacc corresponding to the open area set value a opened through the current direction air conditioning.

When the counting time counted by the controller coincides with the reference time of the accumulated operation time corresponding to the open area setting value, it is determined whether the open area setting value matches the final setting value of the open area setting value. It is a step (S5).

When the counting time counted by the control unit 20 coincides with the reference time value of the cumulative operation time Tacc determined by the open area setting value a, the open area setting value a is opened. It is determined whether or not the final open area set value (a).

That is, the controller 20 determines whether the open area set value (a), which is counted by the control unit 20 and coincides with the reference time value of the accumulated operation time (Tacc), is the fifth open area set value (a) of 100% of the open area.

If the fifth open area setting value (a) does not allow any further open area to be changed, the direction air conditioning operation is stopped.

If the open open area set value is not the final open area set value, the control unit stores the open area set value corresponding to the next step in step S6.

When the control unit 20 completes the coefficient for the reference time of the accumulated operation time Tacc corresponding to the open area set value a, the control unit 20 returns the open area set value a of the next step. Store in

For example, if the currently open area set value (a) was 20% of the first open area set value (a), the control unit 20 stores the open area set value (a) corresponding to 40%. will be.

In addition, when the storing of the open area set value (a) of the next step is completed in the control unit 20, opening the second opening of the housing in the same manner as the open area set value of the perfume supply device stored in the control unit (S2). As is executed, the operation of the direction air conditioning is circulated.

What has been described above is just one embodiment for implementing the vehicular direction air conditioning apparatus, the present invention is not limited to the above embodiment. It will be understood by those skilled in the art that various changes may be made without departing from the spirit of the invention.
