Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention relates to a ventilation / in-vehicle cooling device capable of effectively performing ventilation and cooling in a vehicle cabin.

(Prior Art) Generally, an automobile is provided with air conditioning for air-conditioning the interior of the vehicle. According to this air republication apparatus, the interior of the vehicle can be made a comfortable space regardless of the state of the outside air. I have.

However, even with such an air conditioner, when smoking is performed inside the vehicle, the lack of ventilation capacity causes the interior of the vehicle to be filled with tobacco smoke, and especially when non-smoking occupants are on board. In the meantime, this occupant will feel uncomfortable.

Therefore, conventionally, particularly for the purpose of exhausting such cigarette smoke to the outside of the vehicle, for example, as disclosed in JP-A-60-252019 and JP-A-60-252020, There is a ventilator which is provided with an exhaust duct, and forcibly exhausts tobacco smoke to the outside of the vehicle by a blower attached to the duct.

In a vehicle equipped with such a ventilation device, cigarette smoke that rises even after smoking is exhausted from the exhaust duct to the outside of the vehicle, so that the passengers in the vehicle do not feel discomfort due to this smoke. You can do so.

(Problems to be Solved by the Invention) By the way, at the time of heating the interior of a vehicle with a general air conditioner, when the high temperature air accumulates near the ceiling, the occupants may feel so-called burns or the number of occupants may be large. In such a case, fogging of the vehicle window may occur, and the visual field to the outside of the vehicle may be hindered.

In addition, after a long injection outdoors in the summer, the interior of the vehicle becomes extremely hot, and it takes a long time before the inside of the vehicle is cooled down to a comfortable temperature by the air conditioner mounted on the vehicle. Was.

To prevent such burns and fogging of the windows, and to quickly cool down after summer injections, perform ventilation to exhaust the air inside the vehicle to outside the vehicle during heating, or once exhaust high-temperature air inside the vehicle. Since it is clear that it is more effective to perform in-vehicle cooling from now on, it has been conventional to use such a ventilation device as described above to prevent such fouling and fogging of windows and to perform rapid cooling. There was a proposal to make it happen.

However, in such a proposal, air is exhausted from the ceiling during heating, and warm air blown from the air conditioner mounted on the front of the vehicle flows toward the ceiling, that is, gathers at the head of the occupant. And the air inside the car will be unified because the air inside the car will be exhausted almost from the ceiling.
In addition, since relatively high-temperature air blown out under the feet also flows toward the ceiling, high-temperature air accumulates in the air deviating from such a single flow, and window fogging occurs in the windows of the space. There was a risk of doing so.

Also, when the air conditioner mounted on the vehicle is an air conditioner called a so-called fully automatic air conditioner or auto air conditioner, when cooling after long parking in the summer, cool air flows from the vent outlet in the center of the instrument panel into the vehicle. If it is ventilated by a conventional ventilation device, the cool air will be directly exhausted from the ceiling, and there is a possibility that the high-temperature air in the vicinity of the rear seats may be hardly exhausted. there were.

Further, after such ventilation is completed, the vehicle interior is cooled to a comfortable temperature by the air conditioner mounted on the vehicle, so the time required for the cooling depends on the cooling capacity of the air conditioner mounted on the vehicle. In order to quickly bring the inside of the vehicle to a comfortable temperature, there has been a problem that, in addition to such a ventilation device, an auxiliary cooling device or the like must be mounted on the vehicle.

Furthermore, when a cigarette occupant and a non-smoker occupy an adjacent passenger and smoke, the cigarette smoke flows toward the ceiling. There is a possibility that the gas may flow toward the occupant who does not smoke and then be exhausted from the ceiling. In such a case, the occupant who does not smoke may have a discomfort such as smoking.

The present invention has been made in order to solve such a conventional problem, and a ventilation / in-vehicle interior that can improve the comfort for individual occupants while effectively performing ventilation and cooling in the interior of the vehicle. It is an object to provide a cooling device.

[Constitution of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides a plurality of air conditioning units corresponding to a plurality of set spaces in a vehicle cabin according to an occupant's boarding position. The air flowing from the suction port is introduced into the ceiling air-blowing port into each air-conditioning chamber in the case having a ceiling suction blow-out port and a suction port corresponding to the respective air-conditioning chambers. And a bypass passage for bypassing the introduction passage, and an exhaust port for exhausting the air passing through the introduction passage is formed in a case located at the outlet of each introduction passage. And a cooling means for cooling the air delivered by the delivery means. The delivery means sends the air at the inlet of the introduction passage to the outlet, and the cooling means cools the air delivered by the delivery means. From the ceiling suction outlet An air outlet selection door that moves to an exhaust position for introducing air into the bypass passage, or a ceiling air outlet position for closing the exhaust port and introducing air flowing out of the outlet of the introduction passage to the ceiling suction air outlet. Is provided in each air-conditioning room, and a foot suction position for introducing air flowing from the suction port into the introduction path while closing the population of the bypass path, and introducing air passing through the bypass path to the introduction path while closing the suction port. A suction selection door that moves to either the ceiling suction position or the foot ceiling suction position that opens both the entrance and the suction port of the bypass passage is provided in each air conditioning room, and sucks air near the ceiling of the set space Attach ceiling ducts with ceiling openings to each ceiling suction air outlet, and attach underfoot ducts with foot openings at the foot of the boarding position to each intake port An exhaust duct connected to a vehicle exhaust port for discharging air inside the vehicle to the outside of the vehicle is attached to each exhaust port.

(Operation) The present invention configured as described above operates as follows.

For example, by providing a control means for controlling the blowout selection door, the suction selection door, the sending means and the cooling means, the control means moves the blowout selection door to the exhaust position and the suction selection door to the ceiling suction position, respectively. When the sending means is operated, the air near the ceiling of the setting space is discharged from the ceiling entrance → ceiling duct → ceiling suction outlet → bypass passage exit → bypass passage entrance → introduction passage entrance → introduction passage exit → exhaust outlet → body exhaust outlet. The air is exhausted outside through the vehicle.

In addition, the air under the occupant's feet in the setting space is:
The air is exhausted outside the vehicle via the vehicle exhaust.

In other words, the air inside the car is inhaled through the ceiling and foot openings,
Ventilation that exhausts outside the vehicle can be performed.

Next, the control means moves the blow selection door to the ceiling blow position, moves the suction selection door to the foot suction position, and activates the sending means and the cooling means. After entering the introduction passage via the duct → the suction port and being cooled by the cooling means, it returns to the set space via the ceiling suction outlet → the ceiling duct → the ceiling port.

That is, it is possible to cool the air in the set space sucked from the foot opening and to blow the air from the ceiling opening to the set space.

Further, for example, smoke detection means for detecting cigarette smoke is installed in the vehicle in correspondence with each set space, and when the smoke detection means detects cigarette smoke, the control means exhausts the blowout selection door. If the suction selection door is moved to the ceiling suction position, and the delivery means is operated, the smoke of the cigarette can be introduced from the ceiling entrance → the ceiling duct → the ceiling suction outlet → the bypass passage exit → the bypass passage entrance → introduction The air is exhausted outside the vehicle via the passage entrance → introduction passage exit → exhaust port → body exhaust port.

In other words, tobacco smoke is exhausted from the ceiling entrance to the outside of the vehicle in each set space.

In this way, for each set space, a ventilation function that draws air from the ceiling opening and the foot opening and exhausts the outside of the vehicle, a cooling function that cools the air sucked from the foot opening and blows out from the ceiling opening, Since it has a smoke exhaust function to exhaust cigarette smoke inhaled from the ceiling entrance to the outside of the car, that is, each set space has a ventilation function, cooling function, smoke exhaust function individually, for example, heating Sometimes, if the above ventilation is performed, in each set space, the warm air blown out from the space harmony device mounted on the front part of the vehicle flows toward the ceiling and the feet of the occupant, and gathers at the occupant's head As a result, the occupants during heating can be effectively prevented from being burned.

In addition, since the air in each set space is exhausted from the ceiling and the feet, the air flow in the vehicle is not unitary, and the relatively high temperature of the air blown to the feet by the front air conditioner is reduced. Since the air is exhausted from the foot opening, high-temperature air does not accumulate in a part of the vehicle, and it is possible to effectively prevent fogging of the window.

Furthermore, if the ventilation is performed when the inside of the vehicle is in a high temperature state, such as immediately after parking for a long time in summer, the air inside the vehicle will be exhausted from the ceiling opening and the foot opening, so that the high temperature can be effectively reduced. Of the vehicle can be exhausted.

Further, after the end of such ventilation, the inside of the vehicle can be quickly brought to a comfortable temperature by performing the cooling simultaneously with the front air conditioner.

Furthermore, since ventilation, cooling, and smoke exhaust can be performed individually for each set space in this way, even if an occupant who smokes and a occupant who does not smoke adjoin and ride, for example, smoking is performed during cooling. If a setting space for passengers who do not smoke is set, cool air is sent out from the ceiling opening in this setting space, and smoke is exhausted from the ceiling opening in the setting space for smoking occupants. The flow of air will be directed to the occupant who smokes from the setting space of the occupant who does not smoke cigarettes, and there is no risk that smoke will flow toward the occupant who does not smoke cigarettes. No more discomfort.

Operation control.

First, main controller 2 sets the operation mode based on the flowchart shown in FIG.

The main controller 2 determines whether or not the auto switch 80 is turned on (step 1). If the auto switch 80 is turned on, the main controller 2 automatically operates the ventilation cooling unit 1 (step 2).

On the other hand, when the auto switch 80 is not turned on, the main controller 2 determines whether or not the interlock switch 81 is turned on (step 3).
The ventilation / cooling unit 1 is operated in conjunction (step 4).

Further, when the interlock switch 81 is not turned on, the main controller 2 determines whether or not the manual switch 82 is turned on (step 5). 1 is operated manually (step 6). If none of the switches are turned on, the process returns to step 1 and waits until any of the switches is turned on.

When any of the switches is turned on and one of the operations is started, the main controller 2 sets the OFF switch 83 to the O state.

The mode of 34 is set to the ventilation mode, and the process ends (step 7).

Next, the operation of the automatic operation performed by main controller 2 in step 2 will be described with reference to FIG.

When the auto switch 80 is turned on and the automatic operation is designated, the main control device 2 determines whether or not the OFF switch 83 is turned on.
The applied voltage VF output from the front fan controller 71 is
It is determined whether the operation of the front air conditioner is stopped at 0 V (steps 10 and 11). If the OFF switch 83 is ON or the applied voltage VF is 0 V, the process proceeds to step 7. End the automatic operation.

On the other hand, in the main control device 2, the OFF switch 83 is not turned on,
When it is determined that the input applied voltage VF is higher than 0 V and the front air conditioner is operating, the target outlet temperature T0 output by the front air conditioner control device 70 is input (step 12).

Then, main controller 2 determines whether or not the input target outlet temperature T0 is lower than −10 ° C. (step 13). If the target outlet temperature T0 is lower, that is, if the vehicle interior is extremely hot, such as after parking for a long time in summer, Yes, if the front air conditioner control device 70 determines that maximum cooling is necessary,
To set the mode of each air conditioning room 3, 4 to the ventilation mode, and further, through the fan control device 57, the fans 54, 5
Forced ventilation is performed to rotate 5 at the maximum speed (step 14). In other words, if automatic driving is set after parking for a long time in the summer, the air in each extremely hot setting space will
As shown in FIG. 4 during cooling, each ceiling 33, 34,
The air is sucked into the ventilation cooling unit 1 from the foot openings 36, 37 and the rear parcel openings 39, 40, and is exhausted outside the vehicle.

On the other hand, the main controller 2 determines that the input target outlet temperature T0 is-
If it is not lower than 10 ° C., D air conditioning room 3 and A air conditioning room 4
Set the mode of each air conditioning room 3 and 4 in the order of (steps 15,
16) Further, the fan control device 57 sets the applied voltage to be applied to the fan motor 56 to set the air volume of the ventilation cooling unit 1 (step 17).

The setting of the mode of each of the air conditioning rooms 3 and 4 is performed according to the flowcharts shown in FIGS. 12 and 13, and the setting of the blown air amount is performed according to the flowchart shown in FIG.

First, as shown in FIG. 12, the main control device 2 determines whether or not a ventilation signal has been output from the smoke detection device 72 (step 20).
The actuators 64 and 66 are operated to move the outlet selection door 6 to the exhaust position A and the inlet selection door 8 to the ceiling suction position D, and set the mode of the D air conditioning room 3 to the smoke exhaust mode (step 21).

Next, main controller 2 selects a blowing amount in accordance with the dirt signal output from smoke detector 72 at the same time, and stores this. The main controller 2 sets the amount of air blown to the maximum amount when the large stain signal is output from the smoke detection device 72, and reduces the amount of air blow by a predetermined amount less than the maximum amount when the dirty signal is output. In the case where neither the large dirt signal nor the dirty signal is output, that is, if the small dirt signal is output, the amount of air to be blown is reduced by a predetermined amount smaller than the medium amount.
Specifically, the main control device 2 changes the applied voltage VD applied to the fan motor 56 to 12 V, which is the maximum applied voltage of the fan motor, when a large stain signal is output from the smoke detection device 72.
If the dirty signal is output, VD is set to 8 V, and if the dirty signal is not output, VD is set to 5 V, and this is stored, and the process proceeds to step 16 (steps 22 to 26). That is,

And the mode of the D air conditioning room 3 is set to the cooling mode. Further, the electronic thermo 59 is also operated to operate the rear evaporator 11 (step 28).

Further, the main controller 2 selects whether to activate the air purifier 12 or not according to the ON / OFF state of the DP switch 89 of the operation switch unit 74 (steps 29 and 3).
0).

Further, the main controller 2 applies a voltage equal to the applied voltage VF output by the front fan controller 71 to the fan motor 56 in order to synchronize the air volume of the ventilation cooling unit 1 with the air volume of the front air conditioner. Remember. That is, the application voltage VD applied to the fan motor 56 is set to VF, this is stored, and the process proceeds to Step 16 (Step 31).
Thereby, as shown in FIG. 4, the inside temperature of the vehicle becomes approximately equal to the outside air temperature by performing the forced ventilation or the like,
During cooling when the target outlet temperature T0 becomes −10 ° C. or more and 27 ° C. or less, the air in the D setting space is sucked into the D air conditioning room 3 from the foot opening 36 and the rear parcel opening 39 and is cooled by the rear evaporator 11. Further, when the air cleaning device 12 is in operation, the air is cleaned by the air cleaning device 12 and becomes clean cold air, and is blown out from the ceiling opening 33 into the D setting space.

On the other hand, when the target outlet temperature T0 is not equal to or lower than 27 ° C. in Step 27, the main controller 2 determines that the inside of the vehicle is in the heating state, and operates the actuators 64 and 66,
The outlet selection door 6 is moved to the exhaust position A and the suction selection door 8 is moved to the underfoot suction position E, and the mode of the air conditioning room 3 is set to the ventilation mode (step 32).

Further, main controller 2 sets the applied voltage VD to be applied to fan motor 56 to 5 V in order to reduce the amount of blown air, stores it, and proceeds to step 16 (step 33). This allows
At the time of heating in which the target outlet temperature T0 is higher than 27 ° C., as shown in the heating in FIG. 4, the air in the D setting space is gradually removed from the ceiling opening 33, the foot opening 36, and the rear parcel opening 39, and the outside of the vehicle is discharged. Heating and ventilation to exhaust air to the air.

Next, main controller 2 sets the mode also for A air conditioning room 4 in the same manner as described above.

First, as shown in FIG. 13, the main control device 2 determines whether or not a ventilation signal has been output from the smoke detection device 73 (step 40).
The actuators 65 and 67 are operated to move the outlet selection door 7 to the exhaust position A and the suction selection door 9 to the ceiling suction position D, and set the mode of the A air conditioning room 4 to the smoke exhaust mode (step 41).

Next, main controller 2 simultaneously selects the amount of air to be sent according to the dirt signal output from smoke detector 73, and stores this. Similar to the setting of the D air conditioning room mode, the main control device 2
When a large signal is output from the smoke detector 73, the applied voltage VA applied to the fan motor 56 is set to 12V, which is the maximum applied voltage of the fan motor, and when a dirty signal is output, VA is set to 8V. If no signal is output during dirt, VA
Is set to 5 V, this is stored, and the routine proceeds to step 16 (steps 42 to 46). In other words, as shown in FIG. 4 when smoking,
When smoking is performed in the A setting space, main controller 2 sets the amount of air to be blown in accordance with the degree of contamination (the amount of cigarette smoke) in the vehicle due to smoking, and inhales cigarette smoke from ceiling opening 34. Priority is given to smoke exhaust to the outside of the vehicle.

On the other hand, when the ventilation signal is not output in step 40, the main controller 2 determines whether or not the target outlet temperature T0 input in step 12 is equal to or lower than 27 ° C. It is determined whether the state is the heating state or the heating state (step 47).

Thereby, main controller 2 sets target outlet temperature T0 to 27 ° C.
In the following cases, that is, when the cabin is in a cooling state, the actuators 65 and 67 are operated to
To the ceiling blowing position B, and the suction selection door 9 to the foot suction position C.
, And the mode of the A air conditioning room 4 is set to the cooling mode. Further, the electronic thermo 59 is also operated to operate the rear evaporator 11 (step 48).

Further, main controller 2 selects whether or not to operate air cleaning device 13 according to the ON / OFF state of AP switch 90 of operation switch unit 74 (steps 49 and 5).
0).

Further, the main controller 2 applies the same voltage to the fan motor 56 as the applied voltage VF output by the front fan controller 71 in order to synchronize the airflow of the ventilation cooling unit 1 with the airflow of the front air conditioner. Is stored. That is, the application voltage VA applied to the fan motor 56 is set to VF, this is stored, and the process proceeds to Step 16 (Step 51).
Thereby, as shown in FIG. 4, the inside temperature of the vehicle becomes approximately equal to the outside air temperature by performing the forced ventilation or the like,
At the time of cooling when the target outlet temperature T0 becomes −10 ° C. or more and 27 ° C. or less, the air in the A setting space is sucked into the A air conditioning room 4 from the foot opening 37 and the rear parcel opening 40, and
When the air cleaning device 13 is in operation, the air is cleaned by the air cleaning device 13 and becomes clean cool air, which is blown out from the ceiling opening 34 into the A setting space.

On the other hand, if the target outlet temperature T0 is not equal to or lower than 27 ° C. in step 47, the main controller 2 determines that the inside of the vehicle is in a heating state, and operates the actuators 65 and 67,
The outlet selection door 7 is moved to the exhaust position A and the suction selection door 9 is moved to the underfoot suction position E, and the mode of the air conditioning room 4 is set to the ventilation mode (step 52).

Further, main controller 2 sets the applied voltage VA to be applied to fan motor 56 to 5 V in order to reduce the amount of blown air, stores this, and proceeds to step 16 (step 53). This allows
At the time of heating in which the target outlet temperature T0 is higher than 27 ° C., as shown in the heating in FIG. 4, air in the A setting space is sucked little by little from the ceiling opening 34, the foot opening 37, and the rear parcel opening 40, and Heating and ventilation to exhaust air to the air.

Then, when the mode of each of the air conditioning rooms 3 and 4 is set as described above, the main control device 2 sets the air flow rate of the ventilation cooling unit 1 according to the flowchart shown in FIG.

The suction control device 2 stores the VD stored in steps 20 to 33.
Is compared with the VA stored in steps 40 to 53 (step 60), and a higher value (if they are the same, V
D) is set to the voltage V applied to the fan motor 56 (steps 61 and 62).

Then, main controller 2 causes fan controller 57 to apply this applied voltage V to fan motor 56 and causes fans 54 and 55
Is activated (step 63).

Next, the operation of the ventilation cooling unit 1 when the interlock switch 81 of the operation switch unit 74 is turned on and the interlock operation is set in step 3 will be described with reference to FIG.

First, when the interlock switch 81 is turned on and the interlock operation is specified, the main controller 2 determines whether the OFF switch 83 is turned on or not, and determines whether the applied voltage output from the front fan controller 71 is
It is determined whether VF is 0V, that is, whether the front air conditioner is stopped (steps 70 and 71), and the OFF switch 83 is turned on.
If so, or if the applied voltage VF is 0 V, the process proceeds to step 7 to end the interlocking operation.

On the other hand, in the main control device 2, the OFF switch 83 is not turned on,
When it is determined that the input applied voltage VF is higher than 0 V and the front air conditioner is operating, the target air temperature T0 output by the front air conditioner control device 70 is input (step 72).

Then, main controller 2 determines whether or not the input target outlet temperature T0 is lower than −10 ° C. (step 73). If the target outlet temperature T0 is lower, that is, immediately after long-time parking in summer, the interior of the vehicle is extremely hot. If the front air conditioner control device 70 determines that maximum cooling is necessary, the forced ventilation is performed in the same manner as in step 14 (step 74).

On the other hand, the main controller 2 determines that the input target outlet temperature T0 is-
If the temperature is not lower than 10 ° C., it is determined whether or not the ventilation signal is output from any of the smoke detectors 72 and 73 (step 75). 64 to 67 are operated to move the respective outlet selection doors 6 and 7 to the exhaust position A and the respective inlet selection doors 8 and 9 to the ceiling suction position D, and set the mode of each air conditioning room 3, 4 to smoke exhaust. The mode is set (step 76).

Then, main controller 2 selects an air blowing amount according to the dirt signal output from one of smoke detectors 72 and 73 that has output the ventilation signal, and stores this. More specifically, main controller 2 applies an applied voltage V to fan motor 56 when any of the large dirt signals is output.
No large dirt signal is output to the maximum applied voltage of 12 V, and if any dirty signal is output, V is output to 8 V, and both the large dirty signal and dirty signal are output If not, V is set to 5 V, the applied voltage V is applied from the fan control device 57 to the fan motor 56, and the fans 54 and 55 are operated (steps 77 to 81). That is, in the case of interlocking operation, if smoking is performed in any of the set spaces, main controller 2 sets fans 54 and 55 in accordance with the degree of dirt (the amount of cigarette smoke) in the vehicle due to smoking.
, And preferentially performs smoke exhaust for inhaling cigarette smoke from the ceiling openings 33 and 34 and exhausting the outside of the vehicle.

On the other hand, if no ventilation signal is output in step 75, the main controller 2 determines whether or not the target outlet temperature T0 input in step 72 is 27 ° C. or less, that is, the air conditioning state in the vehicle. It is determined whether is in a cooling state or a heating state (step 82).

Thereby, main controller 2 sets target outlet temperature T0 to 27 ° C.
In the following cases, it is determined that the vehicle interior is in the cooling state, and the actuators 64 to 67 are operated to set the respective outlet selection doors 6, 7 to the ceiling outlet position B, and to set the respective inlet selection doors 8, 9 to. It is moved to the foot suction position C, the mode of each air conditioning room 3, 4 is set to the cooling mode, the electronic thermo 59 is operated, and the rear evaporator 11 is operated (step 8).
3).

Further, the main controller 2 selects the operation or non-operation of the air purifying devices 12 and 13 according to the ON / OFF state of the DP switch 89 and the AP switch 90 of the operation switch unit 74 (step 8).
4-87).

Further, the main controller 2 controls the fan motor 56 by the voltage fan controller 57 which is the same as the applied voltage VF output by the front fan controller 71 in order to synchronize the ventilation volume of the ventilation cooling unit 1 with the ventilation volume of the front air conditioner. To operate the fans 54 and 55 (step 88). As a result, for example, the forced exhaust is performed, and the temperature inside the vehicle becomes approximately the same as the outside air temperature, and the target outlet temperature T0 becomes -10 ° C or more and 27 ° C
At the time of the following cooling, the air in each set space is sucked into the respective air-conditioning rooms 3 and 4 from the foot openings 36 and 37 and the rear parcel openings 39 and 40, and cooled by the rear evaporator 11, Further, when the air purifying devices 12 and 13 are operating, the air is cleaned and becomes clean cold air, and is blown out from the respective ceiling openings 33 and 34 into the respective set spaces.

On the other hand, when the target outlet temperature T0 is not 27 ° C. or less in step 82, the main controller 2 determines that the interior of the vehicle is in a heating state, operates the actuators 64 to 67, and operates the respective outlet selection doors 6, 7 is moved to the exhaust position A, and the respective suction selection doors 8, 9 are moved to the underfoot suction position E.
The modes 3 and 4 are set to the ventilation mode (step 89).

The main controller 2 sets the applied voltage V to be applied to the fan motor 56 to 5 V in order to reduce the amount of air blow, and causes the fan controller 57 to apply this voltage to the fan motor 56,
The fans 54 and 55 are operated (step 90). Thereby, at the time of heating in which the target outlet temperature T0 is higher than 27 ° C., the air in each set space is gradually reduced by a small amount to the ceiling openings 33,3.
4. Air is exhausted outside the vehicle from the foot openings 36, 37 and the rear parcel openings 39, 40.

Next, the operation of the ventilation cooling unit 1 when the manual switch 82 of the operation switch unit 74 is turned on in step 5 and the manual operation is set will be described with reference to FIG.

First, the main control device 2 displays the current ventilation cooling unit 1 on the display device 91 of the operation switch unit 74 as shown in the figure.
Is displayed (step 100).

Then, it is determined whether or not the DR switch 84 has been turned on (step 101). If it has not been turned on, each time one of the fan switches is turned on, the displayed set number of fans is sequentially switched, and the fan motor The applied voltage VD applied to 56 is set to a voltage value corresponding to the set number (step 102).
~ 104). Specifically, the set number of fans displayed as shown in the figure is “1, 2, 3”, and the main controller 2 sets the voltage value corresponding to this “1” to 5 V, The voltage value corresponding to “2” is preset to 8V, and the voltage value corresponding to “3” is preset to 12V. Thereby, main controller 2 sets VD to 5V when “1” is set by the fan switch.
When "2" is set, VD is set to 8V, and when "3" is set, VD is set to 12V.

Further, in the main controller 2, the mode selection switch 86 is turned ON.
Mode, the mode is switched in sequence and displayed,
The process returns to 101 (steps 105 and 106). For example, ventilation mode,
The mode is switched in the order of cooling mode and smoke exhaust mode.

The main controller 2 repeats the above steps 102 to 106 until the DR switch 84 is turned on, thereby setting the mode of the D air-conditioning room 3 and the air flow rates of the fans 54 and 55, and then sets the DR switch When 84 is turned on, the mode of the D air-conditioning room 3 is set to the displayed mode (step 10).
7).

Further, main controller 2 sets the mode of air conditioning room 4 in the same manner.

Main controller 2 determines whether or not AS switch 85 has been turned on (step 108). If it has not been turned on, every time one of the fan switches is turned on, the displayed set number of fans is sequentially switched. Then, the applied voltage VA applied to the fan motor 56 is set to a voltage value corresponding to the set number (steps 109 to 111).

Further, in the main controller 2, the mode selection switch 86 is turned ON.
Each time the mode is changed, the mode is sequentially switched and displayed, and the process returns to step 108 (steps 112 and 113).

The main controller 2 repeats the above steps 109 to 113 until the AS switch 85 is turned on, and sets the mode of the A air-conditioning room 4 and the air flow rate of the fans 54 and 55,
When the switch 85 is turned on, the mode of the air conditioning room 4 is set to the displayed mode (step 114).

Further, main controller 2 sends any higher value (if the same, VD) to fan motor 56 based on the VD and VA set in steps 104 and 111, as in the case of automatic operation. , And the applied voltage V is applied to the fan motor 56 to operate the fans 54 and 55 (step 115).

The main controller 2 operates the air purifiers 12 and 13 according to the ON / OFF state of the DP switch 89 and the AP switch 90,
The non-operation is selected, and the ventilation / cooling unit 1 is operated as set by the occupant by the respective switches (steps 116 to 119).

Thus, when the operation mode is set to the automatic operation, the ventilation cooling unit 1 performs independent ventilation and cooling for each set space according to the air conditioning state of the front air conditioner, except for forced ventilation, When the operation is set to the interlocking operation, the respective set spaces are similarly ventilated and cooled.

Further, when the operation is set to the manual operation, the ventilation and cooling for each set space can be arbitrarily set regardless of the air conditioning state of the front air conditioner, that is, independently of the front air conditioner.

Therefore, in the ventilation / in-vehicle cooling device of the present invention that operates in this manner, when the interior of the vehicle is being heated, the air in the respective set spaces is filled with the ceiling openings 33, 34, the feet 36, 37, and the rear parcel opening 39, Since air can be ventilated outside the vehicle from 40, the warm air blown out from the air conditioner at the front will flow toward the ceiling and the feet of the occupants in each set space, that is, Since the warm air of relatively high temperature is exhausted from the feet of the occupant without being gathered at the head, the burn near the occupant's head can be effectively prevented.

In addition, the air in each setting space is the ceiling opening 33, 34, the foot opening 36,
Since the exhaust air is exhausted from 37 and the rear parcel ports 39 and 40, the air flow inside the vehicle is not unitary, and
Since the relatively high-temperature air blown out of the feet is exhausted from the foot openings 36 and 37, the high-temperature air does not accumulate in a part of the vehicle, and the fogging of the windows can be effectively prevented. Therefore, comfort during heating of the occupant can be improved.

Further, during cooling, when the inside of the vehicle is extremely hot against the outside air, such as after parking for a long time in summer, the ceiling openings 33, 34, the foot openings 36, 37, and the rear parcel openings 39, 40 are similarly provided. The vehicle interior air can be forcibly ventilated, and at this time, the vehicle interior air is exhausted from each of the ceiling opening and the foot opening, so that the high-temperature interior air can be exhausted extremely effectively and quickly. Then, after that, the vehicle interior air sucked from the foot openings 36, 37 and the rear parcel openings 39, 40 is cooled to cool the ceiling 33,
Cooling from the 34 can be performed at the same time as the front air conditioner, so that the inside of the car can be quickly brought to a comfortable temperature. As a result, the time until the inside of the vehicle is brought to the comfortable cooling state is extremely shortened, so that even after parking for a long time in the summer, the occupants do not feel discomfort due to the high temperature inside the vehicle, The vehicle can be made to travel.

Furthermore, at the time of smoking, smoke can be automatically exhausted from the ceiling openings 33 and 34 to exhaust cigarette smoke.
In addition to the ventilation and cooling functions as described above, the multifunction apparatus has a smoke exhaust function similar to the conventional one.

In addition, since ventilation, cooling, or smoke exhaust can be independently performed for each of the setting spaces, for example, an occupant who smokes and a occupant who does not smoke ride together adjacent to the A setting space and the D setting space. Even if smoking is performed during cooling,
As shown in the figure, cool air is sent from the ceiling entrance of the D setting space,
The air can be exhausted from the ceiling opening of the A setting space, that is, air can flow from the non-smoking occupant to the smoking, so that the non-smoking occupant does not give a discomfort such as smoking. Therefore, the comfort for each occupant can be improved.

The main control device 2 exemplified in the above embodiment is an example of a device for controlling the ventilation / in-vehicle cooling device of the present invention, and is not limited to the exemplified device configuration and control contents.

Further, in the above-described embodiment, the ventilation and cooling unit 1 in which the air conditioning rooms 3 and 4 are provided corresponding to the D setting space on the driver's seat side and the A setting space on the passenger seat side in the vehicle is illustrated. The cooling unit is not limited to this, and may be any unit provided with an air-conditioning room corresponding to a set space set according to the occupant's boarding position. For example, a vehicle equipped with an air-conditioning room corresponding to each seat divided into four spaces according to each seat) or an air-conditioning room corresponding to each space divided into front and rear seats Needless to say, a room may be provided.

Further, in the above embodiment, the fan 54, 55 is driven by one fan motor 56. However, the fan 54, 55 may be driven exclusively by two fan motors. Of course. or,
Similarly, the rear evaporator 11 may be provided in each of the introduction passages 50 and 51, respectively.

Further, the amount of air blown by the fans 54 and 55 does not have to be set in accordance with the voltage applied to the fan of the front air conditioner, that is, the number of revolutions as in the above-described embodiment. Considering the balance of the above, it is desirable to set a large number.

The smoke detectors 72 and 73 with a built-in microcomputer are exemplified as those for detecting cigarette smoke. However, the present invention is not limited to this, and a general so-called optical sensor or gas sensor may be used. Of course, if the amount of smoke of the tobacco smoke exceeds a certain level, the smoke may be controlled to be exhausted.

Further, as a method for determining whether the air conditioning in the vehicle is cooling or heating. Not limited to the target air temperature calculated by the front air conditioner control device 70 as in the above embodiment, a sensor or the like for detecting information on air conditioning in the vehicle compartment is connected to the main control device 2, and the main control device 2 Of course, the judgment may be made. It is also possible to determine whether the air conditioner is in a cooling state or a heating state by the state of the outlet of the front air conditioner, that is, the so-called outlet mode, instead of the target outlet temperature.

[Effects of the Invention] As is clear from the above description, the present invention has the following effects.

Ventilation function that inhales air in each setting space from the ceiling and foot openings and exhausts it out of the vehicle, cooling function that cools the air inside the vehicle sucked from the foot openings and blows out from the ceiling opening, and suction from the ceiling opening And a smoke exhaust function for exhausting the smoke of the tobacco to the outside of the vehicle.In other words, each set space has a ventilation function, a cooling function, and a smoke exhaust function. The warm air blown out from the air conditioner installed in the front of the vehicle flows toward the ceiling and the feet of the occupant, and does not collect on the occupant's head. It is possible to effectively prevent sprouts.

In addition, in such ventilation at the time of heating, since the air in each set space is exhausted from the ceiling and the feet, the air flow in the vehicle is not unitary, and the air conditioning of the front part is further reduced. Since relatively high-temperature air blown down from the feet by the device is exhausted from the underfoot opening, high-temperature air does not accumulate in a part of the vehicle, and window fogging is effectively prevented. Will be able to Thereby, comfort during heating of the occupant can be improved.

Furthermore, if the ventilation is performed when the inside of the vehicle is in a high temperature state, such as immediately after parking for a long time in summer, the air inside the vehicle will be exhausted from the ceiling opening and the foot opening, so that the high temperature can be effectively reduced. The air inside the vehicle can be exhausted, and after such ventilation has been completed, the inside of the vehicle can be quickly brought to a comfortable temperature by performing cooling at the same time as the air conditioner in the front part. Become. As a result, the time until the inside of the vehicle is brought to the comfortable cooling state is extremely shortened, so that even after parking for a long time in summer, the occupants do not feel discomfort due to the high temperature inside the vehicle,
The vehicle can be driven quickly.

Furthermore, at the time of smoking, smoke exhaust can be performed to automatically exhaust cigarette smoke from the ceiling entrance, so in addition to the above-described ventilation and cooling functions, a multi-function having a smoke exhaust function similar to the conventional one is provided. It becomes something.

In addition, since ventilation, cooling, and smoke exhaust can be individually performed for each set space, a passenger who smokes and a passenger who does not smoke adjoin each other and smoke, for example, even if smoking is performed during cooling. If you set a setting space where no occupants can get on, cool air is sent from the ceiling opening in this setting space, and smoke is exhausted from the ceiling opening in the setting space of the smoking occupant, so that the flow of air is tobacco. Since the setting space of the occupant who does not smoke is directed to the setting space of the occupant who smokes, there is no possibility that smoke will flow toward the occupant who does not smoke, and discomfort such as smoking for the occupant who does not smoke , And the comfort for each occupant can be improved.
