Description

[Detailed description of the invention] [Purpose 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 interior.

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

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 the cigarette 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, when heating the interior of a vehicle with a general air conditioner, high-temperature air accumulates in the vicinity of the ceiling. In some cases, fogging of the vehicle window may occur, and the field of view to the outside of the vehicle may be hindered.

Also, after parking for a long time 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 lowered to a comfortable temperature by the air conditioner mounted on the vehicle. Was.

In order to prevent such burns and fogging of windows, and to quickly cool down after parking in summer, 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 only necessary to cool the interior of the vehicle afterwards, there has been a proposal to use a conventional ventilator to prevent such fouling and fogging of the window and to perform rapid cooling.

However, if air is exhausted from the ceiling during heating, the warm air blown from the air conditioner mounted on the front of the vehicle will flow toward the ceiling, that is, it will gather at the occupant's head, There is a risk that it will give you some damage.

Also, since the air inside the vehicle is almost exhausted from the ceiling, the flow of air inside the vehicle becomes unitary, and the relatively high-temperature air blown under the feet also flows toward the ceiling. However, high-temperature air accumulates in a space deviating from such a single flow, and there is a risk that window fogging will occur in a window located in such air, which is effective in preventing window fogging. There was a problem that it could not be performed.

Furthermore, when the air conditioner mounted on the vehicle is an air conditioner called a so-called fully automatic air conditioner or an auto air conditioner, such an air conditioner applies cold air to the center of the instrument panel during cooling. Since it is designed to blow out from the vent outlet into the car,
This cold air is directly exhausted from the ceiling, and there is also a problem that high-temperature air near the rear seat is hardly exhausted.

In addition, after the ventilation is completed, the vehicle cabin will be cooled to a comfortable temperature by the air conditioner mounted on the vehicle, but the time required for this will be determined by the cooling capacity of the air conditioner, In order to quickly bring the inside of the vehicle to a comfortable temperature, an auxiliary cooling device or the like must be mounted on the vehicle in addition to such a ventilating device, and there is a problem that the function is small.

The present invention has been made to solve such a conventional problem, and an object of the present invention is to provide a ventilation / in-vehicle cooling device capable of effectively performing ventilation and cooling in a vehicle cabin. .

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention flows from a rear suction port into a case formed with a ceiling suction outlet and a rear suction port. An introduction passage for introducing air into the ceiling suction outlet; and a sub-introduction passage formed substantially parallel to the introduction passage and having both ends opened toward the ceiling suction outlet and the rear intake. An exhaust port for exhausting air that has passed through the introduction passage is formed in the case located at the outlet, and a fan device that sends out the air at the inlet of the introduction passage to the outlet in the introduction passage, and air that is sent out by the fan device. A cooling means for cooling is provided, and by closing an opening facing the ceiling suction outlet of the introduction passage, air flowing out from the outlet of the introduction passage is introduced into the exhaust outlet while air flowing from the ceiling suction outlet is sub-introduced. aisle A first door that selectively moves to any of an exhaust position to be introduced, or a ceiling outlet position for introducing air flowing out of the outlet of the introduction passage into the ceiling suction outlet by closing the discharge port. The rear suction position where the air flowing from the rear suction port is introduced into the introduction passage by closing the opening on the rear suction port side of the sub-introduction passage, and the sub-introduction passage is closed by closing the rear suction port The ceiling suction position for introducing the passed air into the introduction passage, or both the air flowing from the rear suction port and the air passing through the sub-introduction passage by being located between the rear suction position and the ceiling suction position. A second door, which is selectively moved to any position of the rear ceiling suction position to be introduced into the introduction passage, is provided at the rear suction port, and the ceiling opening for sucking air near the ceiling in the vehicle is formed. The constructed ceiling duct is attached to the ceiling intake air outlet, the rear underfoot duct, which is located under the rear seat and has a rear undercarriage, is attached to the rear intake, and one end of the vehicle exhaust vents to exhaust air inside the vehicle to the outside of the vehicle The other end of the exhaust duct attached to the exhaust port is attached to the exhaust port.

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

For example, by providing control means for controlling the first door, the second door, the fan device, and the cooling means, the control means moves the first door to the exhaust position and moves the second door to the rear ceiling suction position. When the fan device is activated,
First, of the air inside the vehicle, the air near the ceiling passes through the ceiling entrance → ceiling duct → ceiling suction outlet → sub introduction passage exit → sub introduction passage entrance → introduction passage entrance → introduction passage outlet → exhaust outlet → body exhaust outlet. Exhausted outside the vehicle.

Further, the air below the rear seat is exhausted to the outside of the vehicle via the rear foot opening → the rear foot duct → the rear suction port → the introduction passage entrance → the introduction passage exit → the exhaust port → the vehicle body exhaust port.

That is, it is possible to perform ventilation in which the air inside the vehicle is sucked in from the ceiling opening and the rear lower opening, and is exhausted outside the vehicle.

Next, the first door is moved to the ceiling blowing position and the second door is moved to the rear suction position by the control means, and the fan device and the cooling means are operated. After entering the introduction passage via the foot duct → rear suction port, and being cooled by the cooling means, it returns to the vehicle interior via the ceiling suction outlet → ceiling duct → ceiling opening.

In other words, it cools the air inside the vehicle that has been sucked in from the rear lower opening,
This can be cooled by blowing it out from the ceiling opening.

Further, for example, smoke detection means for detecting cigarette smoke is installed in the vehicle compartment, and when the smoke detection means detects cigarette smoke, the control means moves the first door to the exhaust position,
If the second door is moved to the ceiling suction position and the fan device is operated, the smoke of the cigarette is discharged from the ceiling entrance → the ceiling duct → the ceiling intake air outlet → the sub introduction passage exit → the sub introduction passage entrance → the introduction passage. The air is exhausted out of the vehicle via the entrance → the exit of the introduction passage → the exhaust port → the exhaust port of the vehicle body.

In other words, smoke exhaust can be performed in which the smoke of tobacco is inhaled from the ceiling entrance and exhausted outside the vehicle.

As described above, the ventilation function of inhaling the air inside the vehicle from the ceiling opening and the rear foot opening and exhausting the air outside the vehicle, the cooling function of cooling the air inside the vehicle sucked from the rear foot opening and blowing out the ceiling opening, and the cooling function of the ceiling opening Since it has a smoke exhaust function to exhaust inhaled cigarette smoke to the outside of the vehicle, if the above ventilation is performed during heating, the warm air blown out from the air conditioner mounted on the front part of the vehicle will be heated by the ceiling and rear seats The air flows toward the lower part, that is, it does not gather at the occupant's head, and the relatively high-temperature warm air is exhausted from the rear lower leg located at the lower part of the rear seat. It will be possible to effectively remove ash.

In addition, if such ventilation is performed at the time of heating, the air inside the vehicle is exhausted from the ceiling and the feet under the rear seats, so that the flow of air inside the vehicle is not unitary, and
Since the relatively high-temperature air blown out under the feet is exhausted from the rear foot openings, the high-temperature air does not accumulate in a part of the vehicle, so that the fogging of the windows can be effectively prevented. Become.

Furthermore, if the above-described ventilation is performed when the inside of the vehicle is in a high temperature state, such as immediately after parking in the summer, the air inside the vehicle is exhausted from the ceiling opening and the rear lower opening under the rear seat, so that the rear High-temperature air in the vicinity of the seat is also exhausted from the rear lower opening, so that high-temperature air inside the vehicle can be effectively exhausted.

Further, after the ventilation is completed, by performing the cooling at the same time as the cooler provided in the instrument panel, the inside of the vehicle can be quickly brought to the comfortable temperature.

The first door 30 and the second door 31 are driven and controlled by a first door actuator and a second door actuator (not shown) similar to those used in the air conditioner of the front part. Has become.

The operation of the thus configured ventilation / in-vehicle cooling device can be controlled by, for example, the control device 60 shown in FIG.

The control device 60 is constituted by a so-called microcomputer, to which a front fan control device 61, an outside air sensor 62, an inside air sensor 63, and a smoke detection device 64 are connected as shown.

The front fan control device 61 is a device that controls a fan provided in an air conditioner mounted on the front part, and applies an applied voltage applied to a fan motor that drives the fan to a control unit 66 described below. Output. That is, the front fan control device 61 outputs a voltage applied to the fan corresponding to the amount of air blown by the air conditioner in the front part. Here, an air conditioner in which the number of revolutions of the fan is adjusted in three stages is mounted on the front part, and the applied voltage is
High rotation voltage, medium rotation voltage, and low rotation voltage.

Further, the outside air sensor 62 and the inside air sensor 63 are sensors for detecting the temperature outside the vehicle and the temperature inside the vehicle, and share the conventional general ones used in the air conditioner in the front part.

Further, the smoke detection device 64 is attached to the ceiling portion 40 in the vehicle, and detects the contamination of the air in the vehicle, particularly, the smoke of cigarettes.

The smoke detector 64 is commercially available in recent years. The smoke detector 64 outputs a signal indicating each time based on a sensor unit such as a so-called optical sensor or a gas sensor and the degree of air contamination detected by the sensor unit. And a processing unit for performing the processing. Specifically, the smoke detection device 64 outputs three types of dirt signals (large dirt, dirty, and small dirt) to a control unit 66 described later according to the degree of dirt in the vehicle.

The control device 60 includes an air-conditioning state determination unit 65 for inputting the outside air temperature detected by the outside air sensor 62.

As shown in FIG. 3, the air-conditioning state determination unit 65 determines whether the inside of the vehicle is in a cooling state or a heating state according to the outside air temperature detected by the outside air sensor 62. Specifically, the air-conditioning state determination unit 65 determines whether the outside air temperature is higher than a predetermined temperature range a to b having hysteresis serving as a reference for determining whether the air conditioner is in the heating state or the cooling state. Determines that the inside of the vehicle is in a cooling state, while if the outside air temperature is lower than the predetermined temperature range a to b, it is determined that the inside of the vehicle is in a heating state. or,
Within the predetermined temperature ranges a and b, it is determined that the already determined air conditioning state is maintained.

It is also possible to determine whether the air conditioner is in a cooling state or a heating state according to the state of the air outlet of the air conditioner in the front part, that is, a so-called mode.

Then, based on the above determination, the air-conditioning state determination unit 65
When it is determined that the current air-conditioning state is the cooling state, a cooling signal is output to the control unit 66 when it is determined that the air-conditioning state is the heating state.

Further, the control device 60 includes a ventilation / cooling switching determination unit 67 for inputting the inside air temperature detected by the inside air sensor 63.

As shown in FIG. 4, the ventilation / cooling switching determination unit 65
Based on the inside air temperature detected by the inside air sensor 63, it is determined whether the vehicle is in a state to be ventilated or in a state to be cooled. This is because, as described above, if the vehicle is parked for a long time in summer or the like, the temperature inside the vehicle becomes extremely high compared to the outside air temperature. This is for determining the switching from the ventilation to the cooling. Specifically, the ventilation / cooling switching determination unit 67 determines whether ventilation is to be performed when the internal air temperature is higher than a predetermined temperature range c to d having hysteresis as a reference for determining whether to perform ventilation or cooling. If the internal temperature is lower than the predetermined temperature range c to d, it is determined that cooling is required.
Also, within the predetermined temperature range c to d, it is determined that the state already determined is maintained.

Then, based on the above determination, the ventilation / cooling switching determination unit 67 outputs a ventilation signal when determining that the current state is a state to be ventilated, and outputs a cooling signal when determining that the current state is a state to be cooled. The data is output to the control unit 66.

The control unit 66 controls the operation of the rear evaporator 33, the first door 30, the second door 31, the fan device 32, and the air purifier 34 based on these signals.

When a heating signal is input from the air-conditioning state determination unit 65, the control unit 66 outputs an exhaust signal for moving the first door 30 to the exhaust position A to the first door actuator 68 that drives the first door 30. It is supposed to do. At the same time, the control section 66 outputs a rear ceiling suction signal for moving the second door 31 to the rear ceiling suction position E to the second door actuator 69 for driving the second door 31.

Further, in that case, the controller 66 applies a voltage corresponding to the applied voltage output from the front fan control device 61 to the fan motor 32b. Specifically, the control unit 66 sets the voltage for rotating the fan 32a at the maximum rotation speed when the high rotation voltage is input, and is lower than the maximum rotation speed by the predetermined rotation speed when the medium rotation voltage is input. When a voltage for rotating the fan 32a at a medium rotation speed is input, and a small rotation voltage is input, a voltage for rotating the fan 32a at a small rotation speed lower than the medium rotation speed by a predetermined rotation speed is applied to the fan motor 32b. It has become.

That is, as shown in FIG. 5, during heating for heating the inside of the vehicle, the air conditioner in the front portion normally heats the air introduced from the outside air and supplies it to the vehicle interior.
When a heating signal indicating this state is output from the air-conditioning state determination unit 65, the amount of in-vehicle air corresponding to the supply amount of the hot air is supplied to the ceiling opening 41, the rear foot opening 45, and the rear parcel opening 48. The doors 30, 31 and the fan 32a are provided so as to perform heating and ventilation in which air is sucked in from the vehicle body and exhausted from the vehicle body exhaust port 50 to the outside of the vehicle.
Is activated.

On the other hand, when a cooling signal is input from the air-conditioning state determining unit 65, the control unit 66 determines whether to perform ventilation or cooling based on a signal output from the ventilation / cooling switching determination unit 67.

When the ventilation signal is output from the ventilation / cooling switching determination unit 67, the control unit 66 outputs an exhaust signal to the first door actuator 68 and outputs the first door 30
Is output to the exhaust position A, and a rear ceiling suction signal is output to the second door actuator 69 to move the second door 31 to the rear ceiling suction position E.

Further, the control unit 66 outputs a voltage for rotating the fan 32a at the maximum rotation speed to the fan motor 32b regardless of the applied voltage output by the front fan control device 61.

That is, as shown in FIG. 5, when the inside temperature of the vehicle is extremely high as compared with the outside temperature during the cooling operation for cooling the inside of the vehicle, as shown in FIG. In order to perform this, the control unit 66 performs forced ventilation in which the air inside the vehicle is drawn in from the ceiling opening 41, the rear foot opening 45 and the rear parcel opening 48 while the fan 32a is rotated at the maximum rotation speed, and is exhausted from the vehicle body exhaust opening 50 to the outside of the vehicle. Each door to do
30, 31 and the fan 32a are operated.

Further, when the cooling signal is output from the ventilation / cooling switching determination unit 67, the control unit 66 outputs a ceiling blowing signal for moving the first door 30 to the ceiling blowing position B to the first door actuator 68, A rear suction signal for moving the two doors 31 to the rear suction position C is output to the second door actuator 69.

Further, in that case, the control unit 66 outputs a voltage corresponding to the applied voltage output by the front fan control device 61 to the fan motor 32b, and also operates the solenoid valve 55 and the air purifier 34. ing.

In other words, as shown in FIG. 5, when the inside temperature of the vehicle becomes about the outside air temperature due to the forced ventilation during the cooling, as shown in FIG.
The control unit 66 rotates the fan 32a in accordance with the rotation of the front fan while rotating the rear foot opening 45 and the rear parcel opening.
The in-vehicle air taken in from 48 is cooled by a rear evaporator 33 and further purified by an air purifier 34 so that clean cool air is blown out from the ceiling opening 41 into the vehicle.

In addition, when any of the dirt signals is input from the smoke detection device 64, the control unit 66, regardless of the above control,
The exhaust signal is output to the first door actuator 68, and a ceiling suction signal for moving the second door 31 to the ceiling suction position D is output to the second door actuator 69.

Further, in this case, the control unit 66 applies a voltage corresponding to the dirt signal output from the smoke detection device 64 to the fan motor 32b. Specifically, similarly to the case of the heating and ventilation, the control unit 66 sets the voltage for rotating the fan 32a at the maximum rotation speed when the large dirt signal is input, and the maximum rotation when the dirty signal is input. When a small signal is input, the fan 32a is rotated at a small rotation speed lower than the medium rotation speed by a predetermined rotation speed. The voltage is applied to the fan motor 32b.

That is, as shown in FIG. 5, at the time of smoking in the vehicle, the control unit 66 rotates the fan 32a in accordance with the degree of dirt (the amount of cigarette smoke) in the vehicle due to smoking, and the smoke of the cigarette is changed. The doors 30, 31 and the fan 32a are operated so that smoke is exhausted from the ceiling opening 41 and exhausted from the vehicle body exhaust opening 50 to the outside of the vehicle.

The control device 60 thus configured operates the ventilation / in-vehicle cooling device of the present invention in accordance with the operation flowchart shown in FIG.

First, the control unit 66 determines whether or not any of the dirt signals is output from the smoke detection device 64 (Step 1).
If any of the dirt signals has been output, an exhaust signal is output to the first door actuator 68 and a ceiling suction signal is output to the second door actuator 69, and the first door 30 is moved to the exhaust position A and the second door actuator is moved to the second position. The door 31 is moved to the ceiling suction position D.
Further, the control unit 66 applies a voltage corresponding to the dirt signal to the fan motor 32b, rotates the fan 32a according to the dirt inside the vehicle, inhales cigarette smoke from the ceiling opening 41, and puts this out of the vehicle. Exhaust. This makes it possible to remove the discomfort caused by cigarette smoke to passengers and smokers other than the smoker, similarly to the conventional ventilation device (step 2).

On the other hand, if none of the dirt signals has been output in step 1, the control unit 66
Activate Then, the air-conditioning state determination unit 65 inputs the outside air temperature output by the outside air sensor 62 (step 3), and determines whether the air-conditioning state in the vehicle is the heating state based on this (step 4).

When the air-conditioning state determination unit 65 determines that the air conditioner is in the heating state and outputs a heating signal, the control unit 66 sends an exhaust signal to the first door actuator 68 and a rear ceiling suction to the second door actuator 69. A signal is output, the first door 30 is moved to the exhaust position A, the second door 31 is moved to the rear ceiling suction position E, and a voltage corresponding to the applied voltage output by the front fan controller 61 is output to the fan motor 32b. To perform heating and ventilation (step 5).

On the other hand, in step 4, when the air-conditioning state determination unit 65 determines that the vehicle is in the cooling state and outputs a cooling signal,
The control unit 66 activates the ventilation / cooling switching determination unit 67. Then, the ventilation / cooling switching determination unit 67 inputs the inside air temperature output by the inside air sensor 63 (Step 6), and determines whether or not it is in a state to be ventilated based on this (Step 7).

Then, when the ventilation / cooling switching determination unit 67 determines that it is in a state to be ventilated and outputs a ventilation signal, the control unit 66
Inputs the exhaust signal to the first door actuator 68 and the rear ceiling suction signal to the second door actuator 69, and moves the first door 30 to the exhaust position A and the second door 31 to the rear ceiling suction position E.
To each other.

Further, the control unit 66 applies a voltage for rotating the fan 32a at the maximum rotation speed to the fan motor 32b, sucks air in the vehicle from the ceiling opening 41, the rear foot opening 45, and the rear parcel opening 48 and exhausts the air outside the vehicle. (Step 8).

On the other hand, when the ventilation / cooling switching determination unit 67 determines that cooling should be performed and outputs a cooling signal, the control unit 66 sends a ceiling blowout signal to the first door actuator 68 and a second door actuator 69. A rear suction signal is output, and the first door 30 is moved to the ceiling blowing position B and the second door 31 is moved to the rear suction position C. At the same time, the control unit 66 outputs a voltage corresponding to the applied voltage output from the front fan control device 61 to the fan motor.
32b, and the solenoid valve 55 and the air purifier 34 are operated. As a result, the air inside the vehicle sucked from the rear foot opening 45 and the rear parcel opening 48 is cooled by the rear evaporator 33, further purified by the air purifier 34, and
The air-conditioning blows out from the vehicle (step 9).

As described above, when the interior of the vehicle is heated, the ventilation that exhausts the interior air according to the amount of warm air supplied to the interior by the air conditioner at the front part from the ceiling opening 41, the rear foot opening 45, and the rear parcel opening 48 outside the vehicle. Therefore, the warm air blown out from the air conditioner at the front will flow toward the ceiling and the lower part of the rear seat, that is, it will not gather at the head of the occupant, and relatively Since the high-temperature warm air is exhausted from the rear foot lower opening 45 located below the rear seat 44, it is possible to effectively remove the burn near the occupant's head. Also, the air inside the car is the ceiling opening 41, the rear foot opening 45
And since it will be exhausted from the rear parcel port 48,
The flow of air inside the vehicle is not unitary, and the relatively high-temperature air blown under the feet is exhausted from the rear foot opening 45, so that the high-temperature air does not accumulate in a part of the vehicle. Thus, it is possible to effectively prevent window fogging. As a result, it is possible to improve the comfort of the rear seat occupant during heating.

Also, during cooling, if the inside of the car is extremely hot relative to the outside air, such as after parking for a long time in the summer, the air inside the car is forcibly ventilated from each of the ports 41, 45, and 48 as well. High-temperature air in the vicinity of the seat 44 is also efficiently exhausted from the rear lower opening 45, so that high-temperature in-vehicle air can be effectively exhausted. Further, thereafter, since the air in the vehicle sucked from the rear foot opening 45 and the rear parcel opening 48 is cooled and purified and the air is blown out from the ceiling opening 41, the inside of the vehicle can be quickly brought to a comfortable temperature. . As a result, the time until the inside of the vehicle is set to the comfortable cooling state is extremely shortened, so even after parking for a long time in summer,
The occupant can quickly drive the vehicle without feeling discomfort due to the high temperature inside the vehicle.

Furthermore, at the time of smoking, regardless of the above-mentioned operation, smoke exhaust for automatically exhausting cigarette smoke from the ceiling opening 41 can be performed. It is a multifunctional device having a smoke exhaust function.

The control device 60 illustrated in the above embodiment is an example of a device that controls the ventilation / in-vehicle cooling device of the present invention, and is not limited to the illustrated device configuration and control contents.
Switches corresponding to the smoke exhaust, heating ventilation, forced ventilation, and cooling are provided, and based on these switches, the first door 30,
Of course, the second door 31, the fan device 32, the rear evaporator 33, and the air purifier 34 may be controlled. That is, you may make it control independently of the air conditioner of a front part.

Although the number of rotations of the fan 32a does not have to be set in accordance with the number of rotations of the fan of the air conditioner in the front part as in the above embodiment, the balance between air conditioning and ventilation in the vehicle of the air conditioner is not required. Considering this, it is desirable to set a plurality.

Further, as a device for detecting cigarette smoke, the smoke detector 64 with a built-in microcomputer has been exemplified. However, the present invention is not limited to this, and a general so-called light sensor or gas sensor may be used. Of course, when the amount of smoke of the smoke exceeds a certain level, the smoke exhaust may be controlled to be performed.

Further, when the inside of the vehicle is air-conditioned by a fully automatic air conditioner as in the above embodiment, the control device and the control device
60 may be communicated to control the operation of the ventilation / in-vehicle air conditioner of the present invention according to the air conditioning control in the vehicle. Needless to say, this makes it possible to more effectively balance the air conditioning in the vehicle.

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

When the inside of the car is heated, ventilation can be performed to exhaust the inside of the car from the ceiling opening and the rear lower opening to the outside of the car, so that the warm air blown out from the air conditioner at the front part is directed toward the ceiling and the lower part of the rear seat This means that the air does not flow to the occupant's head, and that relatively hot air is exhausted from the lower rear leg located below the rear seat. Can be effectively removed. In addition, the flow of air inside the vehicle at that time is not unitary, and the relatively high-temperature air blown under the feet is exhausted from the rear foot opening, so that the high-temperature air may accumulate in a part of the inside of the vehicle. This prevents the fogging of the window and effectively prevents fogging of the window. As a result, it is possible to improve the comfort of the rear seat occupant during heating.

Also, when cooling, when the inside of the vehicle is extremely hot relative to the outside air, such as after parking for a long time in the summer, similarly, the high-temperature inside air is exhausted from the ceiling opening and the rear foot opening to the outside of the vehicle. , The high-temperature air near the rear seat is also efficiently exhausted from the rear lower opening, and the high-temperature in-vehicle air can be effectively exhausted. Further, thereafter, since the air inside the vehicle sucked from the rear lower opening is cooled and the air is blown out from the ceiling opening, the inside of the vehicle can be quickly brought to a comfortable temperature. As a result, the time until the interior 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 of the interior of the vehicle, and quickly. The vehicle can be driven.

Furthermore, at the time of smoking, it is possible to perform smoke exhaust for exhausting cigarette smoke from the ceiling opening, so that in addition to the above-described ventilation and cooling functions, a multifunctional one having the same smoke exhaust function as the conventional one is provided. Become.
