Vehicle air conditioning system {AIR CONDITIONING SYSTEM FOR AUTOMOTIVE VEHICLES}

The present invention relates to an air conditioning device for a vehicle. More specifically, the present invention relates to an air conditioning system for a vehicle. More specifically, the air volume on the rear floor duct side and the air volume on the console duct are configured to be individually adjustable, so that the air volume on the rear seat floor through the rear floor duct and the console duct are adjusted separately. It relates to an air conditioning device for a vehicle that can accurately control the blowing volume of rear seat passengers according to the set size and number of wind volume levels.

Recently, individual air conditioning devices that independently cool and heat multiple areas within a vehicle interior have been developed. For example, individual air conditioning devices for the front and rear seats that independently cool and heat the front and rear seats in the vehicle interior have been developed and are being used.

As shown in FIG. 1, the front and rear seat individual air conditioning devices are console vents that discharge air from the cooling heat exchanger (1) and the heating heat exchanger (3) to the passenger side and floor side of the rear seat, respectively. Vent (5) and Rear Floor Vent (7).

In particular, the console vent (5) and the rear floor vent (7) collect cold air from the rear cold air passage (1a) that passed through the cooling heat exchanger (1) and warm air passage (3a) that passed through the heating heat exchanger (3). The warm air on the ) side is discharged to the console duct (8) and the rear floor duct (9).

Therefore, the cold and hot air from the cooling heat exchanger (1) and the heating heat exchanger (3) are blown to the passenger side and the floor side of the rear seat through the console duct (8) and the rear floor duct (9), respectively. This allows the rear seat part of the vehicle interior to be cooled and heated.

Meanwhile, the front and rear seat individual air conditioning devices include a rear seat mode door (10) installed at the branch point between the console vent (5) and the rear floor vent (7), and a rear seat blower ( 12) is further included.

The rear seat mode door 10 rotates between the console vent 5 and the rear floor vent 7 to adjust the opening amounts of the console vent 5 and the rear floor vent 7.

In particular, the opening amounts of the console vent (5) and rear floor vent (7) are adjusted according to the rear seat air discharge mode status.

For example, when the rear seat air discharge mode is vent mode, the console vent 5 is controlled to open and the rear floor vent 7 is controlled to close. Therefore, cold and warm air can be blown to the torso of the passengers in the rear seat.

And when the rear seat air discharge mode is floor mode, the console vent (5) is blocked and the rear floor vent (7) is controlled to open. Therefore, cold and warm air can be blown to the bottom of the rear seat.

And when the rear seat air discharge mode is Bi-Level Mode, the console vent (5) and the rear floor vent (7) are controlled to open simultaneously. Therefore, cold and warm air can be blown simultaneously to the passenger torso side and floor side of the rear seat area.

The rear seat blower 12, unlike the front seat blower (not shown), which sucks in the external air of the air conditioning case 14, sucks the internal air of the air conditioning case 14, and blows air along the console duct 8. The wind volume and wind pressure of the air blown toward the rear seat passengers are additionally increased.

Therefore, the wind volume and wind pressure of the air blown toward the rear seat passengers are increased. This improves the cooling and heating performance of the rear seat area.

However, in this conventional air conditioning device, the volume of air on the rear floor duct (9) side blown to the rear seat floor side is determined by the front seat blower of the air conditioning case (14), and the air volume on the console duct (8) side blown toward the rear seat passengers is determined by the front seat blower. The amount of air is determined by the front and rear blowers (12).

As a result, it is very difficult and difficult to accurately adjust the air volume on the rear floor duct (9) side and the air volume on the console duct (8) to the set size through control of the front and rear blowers (12). There is.

In particular, when the rear seat air discharge mode is bi-level mode, the air volume distribution between the rear floor duct (9) side and the console duct (8) side is accurately controlled according to the preset size, so that the air discharge to the rear seat floor side and the rear passenger side is controlled. The wind speed must be accurately controlled according to the preset wind speed level.

However, as mentioned above, in the case of the air volume on the console duct (8), there is a disadvantage in that it is difficult to control to the set size because it is simultaneously influenced by the front seat blower and the rear seat blower (12). Because of this disadvantage, the rear blower There is a problem that it is very difficult to accurately control the air volume distribution between the floor duct (9) side and the console duct (8) side according to the set size.

Moreover, in the case of the front-seat blower, it is controlled based on the number of air volume levels set on the front seat side. In this way, with the air volume of the front-seat blowers controlled based on the number of air volume levels set in the front seats, the air volume on the rear floor duct (9) side and the console duct (8) ) has a disadvantage in that it is impossible to match the air volume on the side to the air volume level set for the rear seat.

And because of this disadvantage, when the rear seat air discharge mode is set to bi-level mode, the air volume distribution between the rear floor duct (9) side and the console duct (8) cannot be controlled according to the preset size, and as a result, the rear seat floor There is a problem that the discharged air volume on the front and rear passenger sides is not controlled according to the preset air volume level.

In addition, under the rear seat bi-level mode condition, the number of wind speeds of the front seat blower and the rear seat blower (12) may be changed depending on the user or the internal and external temperature conditions. In this case, the variable front seat blower and the rear seat blower (12) It has the disadvantage of not being able to respond to low air volume.

In particular, as explained above, in the case of the front-seat blower, it is controlled based on the set air volume level on the front-seat side, so when the air volume level of the front-seat blower changes due to a change in the set air volume level on the front-seat side, the disadvantage is that it cannot respond to this. There is.

And because of this disadvantage, the distribution of air volume between the rear floor duct (9) side and the console duct (8) cannot be controlled according to the set ratio, and as a result, the discharge air volume on the rear seat floor side and the rear seat passenger side is less than the set air volume level. There is a problem that it is not properly controlled.

In the end, due to the above-mentioned problems, there is a disadvantage in that under the rear seat bi-level mode conditions, the air blowing volume and number of wind speeds on the rear seat floor side and the rear passenger side are not controlled to a preset state, and because of this disadvantage, the comfort of the rear seat area is significantly reduced.

Figure 2 is a side cross-sectional view showing the configuration of a vehicle air conditioning system according to the present invention.

Hereinafter, preferred embodiments of a vehicle air conditioning system according to the present invention will be described in detail based on the attached drawings (components that are the same as those in the prior art will be described using the same symbols).

First, before looking at the features of the vehicle air conditioning device according to the present invention, the individual front and rear seat air conditioning devices will be briefly described with reference to FIG. 2.

The individual air conditioning units for the front and rear seats include a console vent (5) and a rear floor vent (7) that discharge air from the cooling heat exchanger (1) and heating heat exchanger (3) to the passenger side and floor side of the rear seat, respectively. Includes.

The console vent (5) and the rear floor vent (7) supply cold air from the rear cool air passage (1a) that passed through the heat exchanger (1) for cooling, and warm air passage (3a) that passed through the heat exchanger (3) for heating. The warm air on the side is discharged to the console duct (8) and rear floor duct (9), respectively.

Therefore, the cold and hot air from the cooling heat exchanger (1) and the heating heat exchanger (3) are blown to the passenger side and the floor side of the rear seat through the console duct (8) and the rear floor duct (9), respectively. This allows the rear seat part of the vehicle interior to be cooled and heated.

And the front and rear seat individual air conditioning devices include a rear seat mode door (10) installed at the branch point between the console vent (5) and the rear floor vent (7), and a rear seat blower (12) installed on the console duct (8). ) further includes.

The rear seat mode door 10 rotates between the console vent 5 and the rear floor vent 7 to adjust the opening amounts of the console vent 5 and the rear floor vent 7. In particular, the opening amount of the console vent (5) and the rear floor vent (7) is adjusted according to the rear seat air discharge mode state to control the air distribution between the console duct (8) and the rear floor duct (9).

The rear seat blower 12 additionally increases the wind volume and wind pressure of the air blown toward the passenger side of the rear seat along the console duct 8. Therefore, the wind volume and wind pressure of the air blown toward the passenger's body in the rear seat area are increased.

Next, the features of the vehicle air conditioning system according to the present invention will be examined in detail with reference to FIG. 2.

First, the air conditioning device of the present invention further includes a rear console door (20) installed on the internal passage (8a) of the console duct (8) on the upstream side of the rear seat blower (12).

The rear console door 20 is a flat door, and rotates according to a control signal from the control unit 30, which will be described later, and adjusts the opening amount of the internal passage 8a of the console duct 8.

Accordingly, the amount of air blown toward the body of the rear seat passenger along the console duct 8 is adjusted.

In particular, the amount of air blown toward the torso of rear seat passengers is independently adjusted. As a result, it is possible to control the air blowing volume on the rear seat passenger side according to the set size and number of air volume levels.

And the air conditioning device of the present invention includes a control unit 30 that controls the rear seat mode door 10 and the rear seat console door 20, respectively.

The control unit 30 is equipped with a microprocessor and organically adjusts the opening amounts of the rear mode door 10 and the rear console door 20 according to the number of wind speeds of the front blower 40 and the rear blower 12. It is controlled to blow an air volume that matches the current rear seat air discharge mode and set air volume level to the rear seat floor and rear seat passengers, respectively.

In particular, when the rear seat air discharge mode is bi-level mode, the opening amount of the rear seat mode door (10) with respect to the rear floor vent (7) and the console according to the air volume level of the front seat blower (40) and the rear seat blower (12) It is configured to organically control the opening amount of the rear console door 20 with respect to the internal passage 8a of the duct 8.

Accordingly, the air volume corresponding to the rear seat bi-level mode condition and the wind volume level condition set by the user or the internal and external temperature conditions can be blown to the rear seat floor side and the rear seat passenger side, respectively.

To explain this in more detail, the control unit 30 includes a memory unit 32.

As shown in [Table 1] below, the memory unit 32 contains a mapping table containing control values for the front seat blower and rear seat blower air volume levels and rear seat mode door opening position control values under the rear seat bi-level mode condition.

Rear seat mode door opening position control value for each front and rear blower air volume stage under rear seat bi-level mode conditions (floor vent opening amount: A＞B＞C＞D＞E＞F＞G＞H) Rear seat mode door opening position control value (V) All seat blowers have limited airflow 1st stage 2nd stage 3rd stage 4th gear 5th gear 6th gear 7th gear 8 speed Rear seat blower

The rear seat mode door opening position control value for each air volume level of the front seat blower and the rear seat blower is, in the rear seat bi-level mode, the air blowing volume on the rear seat floor side that varies depending on the air volume level of the front seat blower (40) and the rear seat blower (12), As an opening position correction value of the rear seat mode door 10 to correct for the set rear seat air volume level, it is stored in various ways according to the air volume level of the front seat blower 40 and the rear seat blower 12.

And, as shown in [Table 2] below, the memory unit 32 contains a mapping table of control values for the front seat blower and rear seat blower air volume levels and rear console door opening position control values under the rear seat bi-level mode condition.

Control value of rear console door opening position by front and rear blower air volume stages under rear seat bi-level mode conditions (console duct internal passage opening amount: K＞L＞M＞N＞O＞P＞Q＞R) Rear console door opening position control value (V) All seat blowers have limited airflow 1st stage 2nd stage 3rd stage 4th gear 5th gear 6th gear 7th gear 8 speed Rear seat blower

The rear console door opening position control value for each air volume level of the front seat blower and the rear seat blower is the air blowing volume on the rear seat passenger side that varies depending on the air volume level of the front seat blower 40 and the rear seat blower 12 in the rear seat bi-level mode, This is a correction value for the opening position of the rear console door (20) to correct for the set air volume level of the rear seat, and is stored in various ways according to the air volume level of the front seat blower (40) and the rear seat blower (12).

Meanwhile, the control unit 30 determines whether the current rear seat air discharge mode is the bi-level mode. If the determination result is the bi-level mode, the current front seat blower 40 and the rear seat blower 12 side input. The rear seat mode door opening position control value and the rear seat console door opening position control value corresponding to the blower air volume level and the rear seat blower air volume level are respectively detected in the memory unit 32.

When the detection of the rear seat mode door opening position control value and the rear seat console door opening position control value is completed, the control unit 30 determines the rear seat mode door opening position control value and the rear seat console door opening position control value based on the detected rear seat mode door opening position control value and the rear seat console door opening position control value. The opening position of the rear seat mode door (10) and the opening position of the rear seat console door (20) are variably controlled.

In particular, the opening position of the rear seat mode door 10 with respect to the rear floor vent 7 and the opening position of the rear seat console door 20 with respect to the internal passage 8a of the console duct 8 are controlled, respectively.

Therefore, in the rear seat bi-level mode, the air volume levels of the front seat blower 40 and the rear seat blower 12 are varied according to user settings or internal and external temperature conditions, and the air blowing volume on the rear seat floor side and the passenger side is set to the rear seat air volume level. If it changes differently from , the opening positions of the rear seat mode door 10 and the rear seat console door 20 can be corrected respectively.

As a result, in the rear seat bi-level mode, even if the air volume levels of the front seat blower 40 and the rear seat blower 12 are variable, the discharge air volume on the rear seat floor side and the passenger side can be corrected to match the set rear seat air volume levels.

As a result, regardless of the change in the air volume level of the front seat blower 40 and the rear seat blower 12, the discharge air volume on the rear seat floor side and the passenger side is controlled to match the set rear seat air volume level, thereby maintaining the rear seat area comfortably.

Meanwhile, among the rear seat mode door opening position control values and rear seat console door opening position control values for each air volume stage of the front and rear seat blowers under the rear seat bi-level mode condition stored in the memory unit 32, [Table 1] above, As shown in [Table 2], the condition is that the number of air volume stages of the front seat blower (40) is equal to or lower than the number of air volume stages of the rear seat blower (12), that is, the number of air volume stages of the front seat blower (40) is equal to or lower than the number of air volume stages of the rear seat blower (12). In the condition of one or less, the rear seat mode door opening position control values and the rear seat console door opening position control values are respectively stored as preset default values (A) (K).

Therefore, under the condition that the number of air volume stages of the front seat blower (40) is less than or equal to the number of air volume stages of the rear seat blower (12), the opening position of the rear seat mode door (10) with respect to the rear floor vent (7) and the internal flow path of the console duct (8) The opening position of the rear console door 20 at (8a) is configured to always be consistently controlled to a preset position regardless of the airflow rate of the front seat blower 40 and the rear seat blower 12.

The reason for this configuration is that, under the condition that the air volume level of the front seat blower 40 is less than the air volume level of the rear seat blower 12, even if the air volume number of the front seat blower 40 and the rear seat blower 12 changes, the rear seat floor side and the rear seat passengers This is because the change in air volume on the side does not cause a large deviation compared to the preset air volume level.

Here, the default value (A) among the rear seat mode door opening position control values built into the memory unit 32 is when the opening degree of the rear seat mode door 10 relative to the rear floor vent 7 is 44%. It is desirable to set it accordingly.

In addition, the default value (K) among the rear console door opening position control values built into the memory unit 32 is the opening amount of the rear console door 20 with respect to the internal passage 8a of the console duct 8. It is desirable to set it to correspond to 100%.

Therefore, under the rear seat bi-level mode condition, under the condition that the air volume level of the front seat blower (40) is less than the air volume level of the rear seat blower (12), the opening position of the rear seat mode door (10) opens the rear floor vent (7) by 44%. The opening position of the rear console door 20 is controlled to a position where the console duct 8 is 100% opened.

And, referring to [Table 1] above, among the rear seat mode door opening position control values for each air volume stage of the front seat blower and the rear seat blower under the rear seat bi-level mode condition stored in the memory unit 32, that of the front seat blower 40 In conditions where the number of air volume stages exceeds the number of air volume stages of the rear seat blower (12), the rear seat mode door opening position control values are stored as values (B, C, D, E, F, G, H) less than the default value (A). It is done.

Therefore, under the condition that the number of air volume stages of the front seat blower (40) exceeds the number of air volume stages of the rear seat blower (12), the opening position of the rear seat mode door (10) with respect to the rear floor vent (7) is that of the front seat blower (40). To prepare for a condition where the number of air volume levels is less than the number of air volume levels of the rear blower 12, the rear floor vent 7 is controlled to be further closed.

The reason for this configuration is that, as shown in FIG. 2, under the condition that the number of air volume stages of the front seat blower 40 exceeds the number of air volume stages of the rear seat blower 12, the number of air volume stages of the front seat blower 40 and the rear seat blower 12 This is because, when changing, there is a large deviation in the discharge air volume change on the rear seat floor side and the rear seat passenger side compared to the set size.

In particular, under conditions where the number of air volume stages of the front seat blower (40) exceeds the number of air volume stages of the rear seat blower (12), the air volume of air discharged to the rear seat floor side through the rear floor vent (7) and rear floor duct (9) is This is because it is relatively large, and the ratio of the wind discharge volume to the rear passenger side does not fit the set size.

Therefore, under the condition that the number of air volume stages of the front seat blower 40 exceeds the number of air volume stages of the rear blower 12, the rear floor vent 7 is further closed and the opening amount of the rear floor vent 7 is controlled to be small, The air volume toward the rear floor vent (7) and rear floor duct (9) is reduced, and the discharge air volume toward the rear seat floor side is reduced.

As a result, an increase in the discharge air volume to the rear seat floor side occurs under the condition that the number of air volume stages of the front seat blower 40 exceeds the number of air volume stages of the rear seat blower 12, and the resulting wind exhaust ratio between the rear seat floor side and the rear seat passenger side Deviations can be compensated.

Preferably, as shown in [Table 1], under the condition that the number of air volume stages of the front seat blower 40 exceeds the number of air volume stages of the rear seat blower 12, the rear seat mode door opening position control is controlled for each air volume stage of the front seat blower and the rear seat blower. The values are stored smaller than the default value (A), but as the difference between the air volume levels of the front blower (40) and the rear blower (12) increases, the value is adjusted to gradually close the rear floor vent (7) in inverse proportion to this. It is saved.

For example, as shown in [Table 1], under the condition that the number of air volume stages of the front seat blower (40) exceeds the number of air volume stages of the rear seat blower (12), the deviation in the number of air volume stages between the front seat blower (40) and the rear seat blower (12) As you go from 1st → 2nd → 3rd → 4th → 5th → 6th → 7th, the rear seat mode door opening position control values gradually decrease from B → C → D → E → F → G → H, It is configured to control the rear floor vent 7 in a direction that gradually closes.

Therefore, under the condition that the number of air volume stages of the front blower 40 exceeds the number of air volume stages of the rear seat blower 12, the larger the deviation in the air volume stages between the front blower 40 and the rear blower 12, the more the rear floor vent 7. It is configured to gradually close and reduce the amount of air on the rear floor duct (9) side.

The reason for this configuration is that, as shown in FIG. 2, under the condition that the number of air volume stages of the front seat blower 40 exceeds the number of air volume stages of the rear seat blower 12, the number of air volume stages of the front seat blower 40 and the rear seat blower 12 This is because, as the difference between the two sides increases, the air volume on the rear floor duct (9) side increases proportionally compared to the air volume on the console duct (8) side.

Therefore, under the condition that the number of air volume stages of the front blower 40 exceeds the number of air volume stages of the rear blower 12, the larger the difference between the air volume stages of the front blower 40 and the rear blower 12, the more the rear floor vent 7 ) is gradually blocked, thereby gradually reducing the air volume on the rear floor duct 9 side.

As a result, it is possible to compensate for the difference between the increase in air volume on the rear floor duct (9) side and the resulting air volume on the console duct (8) side, and as a result, the increase in air volume discharged to the rear seat floor side causes the increase in air volume on the rear seat floor side. It is possible to compensate for the windage ratio deviation of the rear seat passengers.

Referring again to FIG. 2, among the rear console door opening position control values for each air volume level of the front and rear blowers under the rear seat bi-level mode condition stored in the memory unit 32, as shown in [Table 2] above. , In conditions where the number of air volume stages of the front seat blower 40 exceeds the number of air volume stages of the rear seat blower 12, the rear console door opening position control values are values (L, M, N, O, P) less than the default value (K). , Q, R).

Therefore, under the condition that the number of air volume stages of the front seat blower (40) exceeds the number of air volume stages of the rear seat blower (12), the opening position of the rear console door (20) with respect to the internal passage (8a) of the console duct (8) is the front seat blower (12). To prepare for a condition where the air volume level of the blower 40 is less than the air volume level of the rear seat blower 12, the internal flow passage 8a of the console duct 8 is controlled to be further closed.

The reason for this configuration is that, as shown in FIG. 2, under the condition that the number of air volume stages of the front seat blower 40 exceeds the number of air volume stages of the rear seat blower 12, the air volume on the console duct 8 side is the air volume of the front seat blower 40. ) is greatly affected by the discharge air volume of the front seat blower 40, and because of the affected air volume of the front seat blower 40, the air volume on the console duct 8 side becomes excessively larger than the set size.

In particular, because the air volume on the console duct 8 side becomes excessively larger than the set size, the windage ratio between the discharge air volume on the rear seat passenger side and the rear seat floor side does not match the set size.

Therefore, under the condition that the number of air volume stages of the front seat blower 40 exceeds the number of air volume stages of the rear seat blower 12, the internal passage 8a of the console duct 8 is further closed to increase the opening amount of the console duct 8. By controlling it small, the excessively large air volume on the console duct (8) side is reduced.

As a result, it is possible to compensate for the excessive increase in air volume on the console duct (8) side and the resulting deviation between the air volume on the console duct (8) side and the rear floor duct (9) side, and as a result, the excessive increase in air volume on the console duct (8) side. It is possible to compensate for the difference in windage ratio between the rear passenger side and the rear seat floor side due to the increase in air volume.

Preferably, as shown in [Table 2], under the condition that the number of air volume stages of the front seat blower 40 exceeds the number of air volume stages of the rear seat blower 12, the rear console door opening position is controlled for each air volume stage of the front seat blower and the rear seat blower. The values are stored below the default value (K), but as the deviation between the air volume levels of the front blower 40 and the rear blower 12 increases, the internal flow path 8a of the console duct 8 is gradually blocked in inverse proportion to this. It is stored as a direction control value.

For example, as shown in [Table 2], under the condition that the number of air volume stages of the front seat blower (40) exceeds the number of air volume stages of the rear seat blower (12), the deviation in the number of air volume stages between the front blower (40) and the rear seat blower (12) As you go from 1st → 2nd → 3rd → 4th → 5th → 6th → 7th, the rear console door opening position control values gradually decrease as L → M → N → O → P → Q → R, It is configured to be controlled in a direction to gradually close the internal passage (8a) of the console duct (8).

Therefore, under the condition that the number of air volume stages of the front blower 40 exceeds the number of air volume stages of the rear seat blower 12, as the difference between the air volume stages of the front blower 40 and the rear seat blower 12 increases, the console duct is inversely proportional to this. The internal flow path (8a) of (8) is gradually closed to reduce the amount of air on the console duct (8) side.

The reason for this configuration is that, as shown in FIG. 2, under the condition that the number of air volume stages of the front seat blower 40 exceeds the number of air volume stages of the rear seat blower 12, the number of air volume stages of the front seat blower 40 and the rear seat blower 12 This is because the larger the deviation, the more the air volume on the console duct (8) is affected by the discharge air volume of the front seat blower (40).

In particular, the air volume on the console duct 8 side is greatly influenced by the discharge air volume of the front seat blower 40, so the air volume on the console duct 8 side becomes excessively large compared to the set size, and the discharge air volume on the rear seat passenger side becomes excessively large. This is because the air volume is excessively increased compared to the air volume discharged from the bottom of the rear seat.

As a result, the windage ratio between the discharged wind volume on the rear seat passenger side and the rear seat floor side does not match the set size, making it impossible to obtain the preset rear seat air volume level.

Therefore, under the condition that the number of air volume stages of the front blower 40 exceeds the number of air volume stages of the rear blower 12, the larger the difference in the number of air volume stages between the front blower 40 and the rear blower 12, the more the console duct 8. By gradually blocking the internal flow path 8a, the amount of air on the console duct 8 side is reduced.

As a result, it is possible to compensate for the excessive increase in the air volume on the console duct (8) side and the resulting windage ratio deviation between the air volume on the console duct (8) side and the rear floor duct (9) side, and as a result, the rear seat The windage ratio between the passenger side and the bottom of the rear seat can be adjusted to the set size.

Referring again to FIG. 2, the control unit 30 turns the rear seat blower 12 on and off according to the air volume level of the front seat blower 40 and the rear seat blower 12 under the rear seat bi-level mode condition. (OFF) is also controlled.

In particular, as shown in [Table 3] below, under the rear seat bi-level mode conditions, the number of air volume stages of the front seat blower 40 exceeds the number of air volume stages of the rear seat blower 12, and the front seat blower 40 and the rear seat blower ( If the deviation between the air volume stages of 12) is more than a preset standard deviation, for example, only in the case of 3 or more stages, the rear blower 12 is configured to be turned off.

Under rear seat bi-level mode conditions, front and rear blower air volume levels are controlled, and rear seat blowers are turned ON and OFF. Rear seat blower ON, OFF control All seat blowers have limited air volume. 1st stage 2nd stage 3rd stage 4th gear 5th gear 6th gear 7th gear 8 speed Rear seat blower

The reason for this configuration is that under the condition that the number of air volume stages of the front seat blower (40) exceeds the number of air volume stages of the rear seat blower (12), the number of air volume stages of the front seat blower (40) exceeds the number of air volume stages of the rear seat blower (12). When the condition and the second condition that the difference between the number of air volume stages of the front seat blower (40) and the air volume stage of the rear seat blower (12) is 3 or more stages are satisfied, the air volume on the console duct (8) side is that of the front blower (40). This is because it is greatly influenced by the discharged air volume.

In particular, when the first and second conditions are satisfied, the discharge air volume on the console duct (8) can be controlled to a preset air volume only with the discharge air volume of the front seat blower (40) without operating the rear seat blower (12). Because there is.

Therefore, when the first and second conditions are satisfied, the rear seat blower 12 is turned off, thereby improving the fuel efficiency of the vehicle without deteriorating the cooling and heating effects of the rear seat area.

According to the air conditioning device of the present invention having such a configuration, the rear console door (20) is installed on the console duct (8), and then the rear console door (20) and the rear seat mode door (10) are connected through the control unit (30). ) are individually controlled, so the air volume on the rear floor duct (9) side and the air volume on the console duct (8) can be adjusted individually.

In addition, since the air volume on the rear floor duct (9) side and the air volume on the console duct (8) can be adjusted individually, the air volume on the rear seat floor through the rear floor duct (9) and the air volume on the rear seat through the console duct (8) can be adjusted individually. The air blowing volume on the passenger side can be accurately controlled according to the set size and number of wind speeds.

In addition, since the rear console door 20 and the rear seat mode door 10 are controlled individually, but are controlled in organic connection with each other, in the rear seat bi-level mode, the rear floor duct 9 and the console duct are connected to each other. (8) The distribution of air volume between sides and each air volume can be accurately controlled according to the preset size.

In addition, in the rear seat bi-level mode, the air volume distribution between the rear floor duct (9) side and the console duct (8) side and each air volume can be accurately controlled according to the preset size, so in the rear seat bi-level mode, the rear seat The air blowing volume and number of wind speeds on the floor side and the rear seat passenger side can be controlled according to the set value, and through this, the comfort of the rear seat area can be improved.

In addition, in the rear seat bi-level mode, the rear console door 20 and the rear seat mode door 10 are organically linked and controlled according to the air volume level of the front seat blower 40 and the rear seat blower 12, so the rear seat blower 40 and the rear seat blower 12 are organically linked and controlled. In the bi-level mode, the air volume on the rear floor duct (9) side and the air volume on the console duct (8) can be variably adjusted depending on the number of air volume stages of the front blower (40) and the rear blower (12).

In addition, in the rear seat bi-level mode, the air volume on the rear floor duct (9) side and the air volume on the console duct (8) can be variably adjusted depending on the number of air volume levels of the front seat blower (40) and the rear seat blower (12). , It is possible to actively respond to changes in the rear floor duct (9) side air volume and console duct (8) side air volume changes that occur due to changes in the air volume levels of the front seat blower (40) and rear seat blower (12) under rear seat bi-level mode conditions. there is.

In addition, it can actively respond to changes in the rear floor duct (9) side air volume and console duct (8) side air volume changes that occur due to changes in the air volume levels of the front seat blower (40) and rear seat blower (12) under rear seat bi-level mode conditions. Therefore, it is possible to compensate for the change in air blowing volume on the rear seat floor side and the rear seat passenger side that occurs when the number of air volume stages of the front seat blower 40 and the rear seat blower 12 changes.

In addition, it is possible to compensate for the change in airflow volume on the rear seat floor side and the rear passenger side that occurs when the air volume number of the front blower 40 and the rear seat blower 12 changes under the rear seat bi-level mode condition, so in the rear seat bi-level mode, Regardless of the change in the air volume level of the front seat blower (40) and the rear seat blower (12), the discharge air volume on the rear seat floor side and the rear passenger side can be controlled to match the set air volume level.
