The environmental condition detection signal of is input to the ECU 160.

The operation panel 150 is provided with various switches 151 to 157 (manual operation means) that allow the operating state of the air conditioning unit 110 to be selected by manual operation by an occupant. As these switches, first, an inside / outside air changeover switch 151 for switching the inside / outside air mode is provided as an inside / outside air manual operation means. Further, as the opening / closing manual operation means, a mode changeover switch 152 for changing over the blowout mode is provided, and the mode changeover switch 152 is composed of one switch, and each blowout mode is sequentially selected by repeatedly pressing. Further, a fan switch 153 for switching the amount of air blown by the blower 115 is provided as a blower manual operation unit. still,
When the fan switch 153 is turned off, the blower 115 is naturally stopped (stop mode), and in conjunction with this, the operation of the refrigeration cycle including the evaporator 122 is stopped and the air conditioner is stopped.

As other switches, a defogger switch 154 for turning on and off a wind defogger (not shown), a set temperature switch 155 for setting a passenger's favorite temperature, and an auto switch 1 for setting an automatic control state.
56, A / C switch 1 for turning on / off the refrigeration cycle including the evaporator 122 of the air conditioning unit 110
56 and the like are provided. Then, the manual operation signals of these switches 151 to 157 are input to the ECU 160.

Incidentally, when the auto switch 156 is turned on, the air conditioning unit 110, that is, the inside / outside air switching door 112, the air mix door 124, and the outlets 1 are provided.
Each of the doors 125a to 127a of the 25 to 127 and the blower 115 are controlled by the ECU 160 as an automatic mode, and each switch 151 to 155 is controlled by an occupant.
If any of the above is selected, the air conditioning state is fixed as the manual mode. In addition, the blowing mode in the auto mode is, here, face, B / L, foot,
Four types of F / D mode are selected.

Next, the operation based on the above configuration will be described. First, from the input signals of the inside air temperature sensor 141, the outside air temperature sensor 142, the solar radiation sensor 143, and the set temperature switch 155 in the operation panel 150 among the plurality of sensor groups 140, the ECU 160 uses TAO according to a predetermined arithmetic expression.

The openings 26a and 127a and the amount of air blown by the blower 115 are controlled.

On the other hand, the operation panel 1 is manually operated by a passenger.
When any one of the 50 switches 151 to 155 is pressed, it is fixed to the operation mode of the switch as the manual mode. However, in the present invention, the cloudiness of the window is changed according to the operating condition at that time. To improve the doors 125a-127 of the outlets 125-127
The function (a characteristic part of the present invention) for controlling a is provided, and the details thereof will be described below with reference to the flowchart shown in FIG.

First, in step S100, it is determined whether or not the air conditioning unit 110 is operating, and if it is operating, it is determined in step S110 whether or not the automatic mode is set. This auto mode is a case where the auto switch 156 is in the ON state as described above.

In the state of the automatic mode, when it is determined in step S120 that the mode change switch 152 is operated, the blowing mode is set to the front window in step S130 and the blowing air amount increases.
Switch to / D mode. If it is determined to be no in both step S110 and step S120, the control state at that time is continued.

On the other hand, if it is determined to be no in step S100, that is, at least as described above, the fan switch 15
If 3 is turned off (stop mode), step S1
At 40, it is determined whether or not the occupant has operated the mode changeover switch 152, and if there is an input operation, the inside / outside air switching door 112 is switched to the outside air introduction side in step S150 to form the RAM mode. That is, when the blower 115 is in the OFF state and the occupant's manual operation is performed, the mode in which the outside air is introduced to blow the air by the vehicle speed is set. Then, when this RAM mode is formed, in step S160, the blowing mode is switched to the face mode in which the amount of air blown to the front window is reduced.

As a result, after the RAM mode is formed, the moisture generated in the air conditioning unit 110 (the condensed water attached to the evaporator 122 when the refrigeration cycle is stopped is evaporated by the residual heat of the heater core 123) first,
Since the air is blown out from the air outlet toward the side other than the front window, here, the face air outlet 126, it is possible to prevent the occurrence of window fogging.

Further, in addition to the above effects, when the auto mode is formed, the originally dehumidified conditioned air is first discharged to the front window, that is, F.
Since it blows out from the defroster outlet 125 of / D,
The window fogging prevention can be effectively operated.

(Second Embodiment) A second embodiment is shown in FIGS. The second embodiment is different from the first embodiment in that, when the automatic mode is formed, the blowing mode is set to the blowing mode in which the amount of air blown to the front window is large in response to repeated operation of the mode changeover switch 152 by the occupant. I am trying to move in order. Further, when the RAM mode is formed, the occupant mode changeover switch 1
In response to the repeated operation of 52, the blowing mode is changed in the order of the blowing mode in which the blowing air amount to the front window is small, and the blowing mode in which only the front window is blown into the blowing mode,
That is, the defroster blowing mode is incorporated.

First, the control of the blowing mode at the time of forming the automatic mode will be described with reference to the flowchart of FIG. In step S200, it is determined whether or not the mode is the auto mode. When the mode change switch (hereinafter, mode SW) 152 is input by the occupant in the auto mode (step S210), first, the blowing mode is set to the mode of the first embodiment. As described above, the mode is switched to the F / D mode in which the amount of air blown to the front window increases (step S2).
20). Further, thereafter, each time the mode SW 152 is input, the blowing mode is switched from a mode in which the amount of air blown to the front window is large to a mode in which the amount is small (F / in steps S230 to S280).
D → foot → B / L → face mode). Then, when the mode SW 152 is input in step S290, the process returns to step S220, and the transition to the blowout mode is repeated. Note that steps S200, S210, S230,
If the determinations in S250, S270, and S290 are negative, the process returns to the start.

Next, using the flowchart of FIG. 4, R
The control of the blowing mode when forming the AM mode will be described. First, in step S300, it is determined whether or not the RAM mode condition is satisfied. If the RAM mode condition is satisfied, the inside / outside air mode is switched to the outside air mode as in the first embodiment (step S301), and the blowout mode is set. Switch to face mode (step S302).

Further, thereafter, the mode SW1 is set by the occupant.
Each time 52 is input, the blowing mode is switched from a mode in which the amount of air blown to the front window is small to a mode in which the amount is large (steps S303 to S3).
At 10, face → B / L → foot → F / D → defroster mode). Here, the defroster blowout mode is incorporated at the end of the blowout modes sequentially shifted, as shown in step S310.

After that, when the mode SW 152 is input (step S311), the RAM mode is once turned off,
That is, when the inside / outside air mode is switched to the inside air mode and the mode SW 152 is further input (step S313), the process returns to step S301, the inside / outside air mode is returned to the outside air mode, and the above-described blowout mode transition is repeated. Incidentally, steps S300, S303, S305, S307, S30
If it is determined to be no in each of 9, S311, and S313,
Return to the start.

As a result, more dehumidified conditioned air can be blown toward the front window when the auto mode is formed, and more moisture is generated in the air conditioner when the RAM mode is formed. Since the air is suppressed from being blown out toward the windshield as much as possible, the anti-fog property can be improved.

When the RAM mode is formed,
After the humid air is blown out from the face outlet 126 or the foot outlet 127 that goes out of the front window, the blowout mode in which only the front window is blown out, that is, the defroster mode can be selected by repeatedly operating the mode SW152. Therefore, the window fogging prevention performance can be improved without using the energy of the vehicle (electric power generated by the blower 115 ON).

(Third Embodiment) A third embodiment of the present invention is shown in FIGS. The third embodiment is different from the second embodiment in that a window defogger is provided in the front window and the window defogger is interlocked when the blowout mode in which the amount of blown air to the front window is increased when the RAM mode is formed. It is designed to be operated.

The configuration of the air conditioner 100 includes the first
In contrast to the one described in the embodiment, the front window (hereinafter, window) 10 is provided with a window defogger (hereinafter, defogger) 170 as a heating unit. As is well known, the defogger 170 has a heating resistance wire embedded in the window 10, receives heat from the battery 180 to generate heat, and removes fogging in the window 10. And this defogger 1
The operation (ON-OFF) of 70 is controlled (automatically controlled) by the ECU 160 based on an environmental condition detection signal from the sensor group 150 or based on a control flow of the present invention described later. The defogger switch 154
Is selected by the manual operation of the occupant, the defogger 170 is operated (manual operation) based on the manual operation signal.

The control when the RAM mode is formed in the above structure will be described with reference to FIG. Basically, it is the same as that of the second embodiment described with reference to FIG.
Steps S308, S310 and S312 in FIG. 4 are changed to steps S308A, 310A and S312A. That is, when the F / D mode and the defroster mode in which the amount of air blown to the window 10 is large are selected, the defogger 170 is operated at the same time (steps S308A and S310A). Then, in step S312A, when the RAM mode is turned off and the inside / outside air mode is switched to the inside air mode, the defogger 17
0 is turned off.

As a result, the defogger 170 can further improve the cloud proof property, and the cloud proof property can be improved with a low noise without the operation noise of the blower 115.

Incidentally, the above steps S308A and S310A
It is preferable that the operating time T1 of the defogger 170 is set to be longer than the operating time T2 set in the automatic control described above. For example, if the operating time T2 of the defogger 170 during the automatic control is 5 minutes, the operating time T1 during the RAM mode formation is 10 minutes.

As a result, the amount of air blown during the formation of the RAM mode is lower than the amount of air blown by the blower 115 during the formation of the auto mode. Cloudiness can be secured.

(Fourth Embodiment) A fourth embodiment of the present invention is shown in FIGS. The fourth embodiment is different from the first to third embodiments in that the amount of introduced outside air is reduced according to the amount of exhaust gas detected by the exhaust gas sensor 144.

FIG. 7 shows an exhaust gas detection amount detected by an exhaust gas sensor 144 as a gas detecting means, and more specifically, the outside air introduction determined by the inside / outside air switching door 112 with respect to the concentration (ppm) of HC. Mouth 11
4 is an outside air opening degree control characteristic diagram in which the opening degree (%) of No. 4 is related and is stored in the ECU 160 in advance.

When the RAM mode is formed,
The inside / outside air switching door 11 is based on the control flow shown in FIG.
The operation of 2 is controlled. That is, in step S400, the current inside / outside air mode is read, and if it is determined in step S410 that the mode is the outside air mode, in step S420, the inside / outside air switching door is opened based on the outside air opening control characteristic described in FIG. The operation of 112 is controlled. Incidentally, step 41
If the result is 0, it returns to the start.

As a result, the invasion of exhaust gas into the passenger compartment during the RAM mode formation can be suppressed as much as possible.

(Other Embodiments) The inside / outside air switching means and the opening / closing means are each of the rotating doors 112, 125a to 127.
Although it has been described as a, it is not limited to this and may be a slide door or a rotary door. Further, although the heating means has been described as the defogger 170, the present invention is not limited to this, and a hot gas cycle or a viscous heater for raising the temperature of the conditioned air may be used.
