A vehicle air conditioner as an embodiment will be described with reference to the drawings.
The vehicle air conditioner of this embodiment is an air conditioner (also referred to as HVAC <Heating, Ventilation and Air-Conditioning>) mounted on the vehicle. Here, an automobile is illustrated as a vehicle equipped with an air conditioner.
In the following embodiment, upstream and downstream are determined based on the air flow direction in the air conditioner.

[I. One Embodiment]
[1. Constitution]
Hereinafter, the configuration of the air conditioner will be described.
The air conditioner is a device that blows out wind by adjusting various parameters related to air conditioning such as air volume and air temperature. In addition to the basic structure that blows air that has been conditioned into the interior of the vehicle (hereinafter abbreviated as “vehicle compartment”), this air conditioner blows air that has been conditioned into a separate chamber (small room) in the passenger compartment. A configuration for discharging air from the chamber to the outside of the vehicle (hereinafter abbreviated as “outside of the vehicle”) is provided.
Here, “wind” means air supplied by the air conditioner. For this reason, “wind” is also referred to as “air”, and “wind” of wind is also referred to as “supply” of air.
First, a basic configuration for blowing air that has been conditioned to the passenger compartment will be described. After that, a detailed configuration for blowing the air conditioned outside the chamber and the vehicle will be described.

[1.1. Basic configuration]
As shown in FIG. 1, the air conditioner 3 includes a blower 33, heat exchangers 34 and 35 interposed in two types of heat exchange circuits 4 and 5, and various dampers D _I , D _M and D _V1. , D _V2 and D _V3 are provided. The air volume is adjusted by the blower 33, the temperature of the air is adjusted by the heat exchangers 34 and 35, and the dampers D _I , D _M , D _V1 , D _V2 and D _V3 whose opening degree is adjusted by an actuator (not shown). Wind intake and blowout destination are adjusted.

  Here, a first heat exchanger 34 that cools (heat exchanges) the air is disposed downstream of the blower 33, and a second heat exchanger 35 that heats (heat exchanges) the air is downstream of the first heat exchanger 34. Has been placed. Further, an evaporator (hereinafter, “first heat exchanger 34” is referred to as “evaporator 34”) is provided as the first heat exchanger 34, and a heater core (hereinafter, “second heat exchanger 35”) is provided as the second heat exchanger 35. Is referred to as “heater core 35”).

--Heat exchange circuit--
One of the two types of heat exchange circuits 4 and 5 is a cooling heat exchange circuit (hereinafter referred to as “cooling circuit”) 4, and the other is a heating heat exchange circuit (hereinafter referred to as “heating circuit”) 5. . An evaporator 34 is interposed in the cooling circuit 4, and a heater core 35 is interposed in the heating circuit 5.

In the cooling circuit 4, in addition to the evaporator 34, a compressor 41, a condenser 42, a receiver 43, and an evaporation valve 44 are interposed in a refrigerant flow path 40 through which the refrigerant circulates.
The compressor 41 is a pressure feeder that pumps the refrigerant. Here, a mechanical compressor 41 driven by the engine 55 is illustrated. The compressor 41 is provided with a clutch 41 a that can connect and disconnect the driving force of the engine 55. The refrigerant pumped by the compressor 41 has a higher temperature and a higher pressure than before the pumping, and flows into the condenser 42.

The condenser 42 is a condenser that cools and condenses the high-temperature and high-pressure refrigerant. The condenser 42 is provided with a fan 42a for promoting the condensation of the refrigerant. The refrigerant condensed by the condenser 42 flows into the receiver 43.
The receiver 43 is a tank that temporarily stores the condensed refrigerant. Furthermore, in the receiver 43, impurities in the refrigerant are removed by the strainer, and moisture in the refrigerant is removed by the desiccant. The refrigerant stored in the receiver 43 flows into the evaporation valve 44.

The evaporation valve 44 is a valve that promotes vaporization (evaporation) of the refrigerant by spraying. The refrigerant whose vaporization is promoted by the evaporation valve 44 flows into the evaporator 34.
The evaporator 34 is a cooler that cools with the latent heat of vaporization of the refrigerant. The refrigerant flowing through the evaporator 34 flows into the compressor 41 again.
When the engine 55 is automatically stopped by the idle stop control or the sailing control, the refrigerant pressure pumping by the compressor 41 is also stopped, and the cooling by the evaporator 34 is slowed down. From the viewpoint of suppressing such slowing of cooling, it is preferable to use a cold storage evaporator having an increased heat capacity for the evaporator 34.

  In the heating circuit 5, the heater core 35 and the engine 55 are interposed in the cooling water circuit 50 in which the cooling water of the engine 55 (also referred to as “LLC <Long Life Coolant>”) circulates and circulates. Yes. The cooling water whose temperature has been increased by exchanging heat with the engine 55 is radiated by the heater core 35, the temperature is lowered, and flows into the engine 55 again. That is, the cooling water heated by cooling the engine 55 repeats the heat exchange cycle cooled by heating the air of the air conditioner 3 with the heater core 35.

-Air conditioning system-
The air conditioner 3 is broadly divided into a main body 3A that sends out conditioned air and a downstream part 3D through which the wind sent from the main body 3A flows.
As shown in FIG. 2, the main body 3 </ b> A has a front portion (also referred to as “center cluster”) that defines a front portion and a lower portion at the center in the width direction of the passenger compartment 2. It is built in the space in the opposite direction).

As shown in FIG. 1, the main body 3A is provided with an air flow path 30 inside a housing 3H (housing).
The flow path 30 is provided with a blower 33 for pumping air, an evaporator 34 for exchanging heat with air, and a heater core 35.

The moisture contained in the air cooled by the evaporator 34 is condensed and removed. Therefore, the evaporator 34 can also be referred to as a “cooling unit” that cools the air sent out by the blower 33, and can also be called a “dehumidifying unit (first dehumidifying unit)” that dehumidifies the air sent out by the blower 33.
Moreover, the apparent humidity (that is, relative humidity) of the air heated by the heater core 35 decreases. Therefore, similarly to the evaporator 34, the heater core 35 can be said to be a “dehumidifying part (second dehumidifying part)” that dehumidifies the air sent out by the blower 33. The evaporator 34 and the heater core 35 dehumidify the air in the flow path 30 in cooperation.

The channel 30 is roughly divided into an upstream channel (hereinafter referred to as “upper channel”) 3U and a downstream channel (hereinafter referred to as “middle channel”) 3M with respect to the upper channel 3U.
In the upper flow path 3U, an outside air introduction path 31U that introduces outside air and an inside air introduction path 32U that introduces inside air (air of the vehicle compartment 2) merge. A blower 33 is disposed downstream of the junction.

An evaporator 34 is provided in the middle flow path 3M, and a first branch path 31M and a second branch path 32M that branch after being branched into two at the downstream of the evaporator 34 and are joined are arranged in parallel.
Further, a heater core 35 is provided in the second branch path 32M. The air that has flowed into the second branch passage 32M flows through the heating of the heater core 35. The first branch 31M is not provided with a heat exchanger, and the air cooled by the evaporator 34 flows as it is.

Two kinds of dampers D _I and D _M are arranged in the flow path 30. These dampers D _I and D _M adjust the flow path of the circulating air.
Here, the damper D _I, illustrates the D _M for swinging (opening and closing) straddling the end of the two flow paths ( "damper D 'from this is also referred to as" door "). For example, the damper D _I, D _M, adjusted opening by an actuator causes the circulating air to the other as well as blocking the flow of air in one of the two flow paths.

The confluence portion of the air introduction passage 31U and inside air introduction path 32U in the upstream path 3U, outside air switching damper D _I is provided. In the case where the opening degree of outside air switching damper D _I in a position to close the downstream end portion of the inside air introduction path 32U with opening the downstream end of the air introduction passage 31U is adjusted (see the solid line in FIG. 1), air-conditioning Outside air (air) is introduced into the device 3, and this outside air is supplied to the passenger compartment 2.

The bifurcation of the first minute branch 31M and the half branch 32M in middle passage 3M, air mix damper D _M is provided.
In the case where the opening degree of the air mixing damper D _M is adjusted to with the position closing the upstream end of the second minute branch 32M to open the upstream end of the first minute branch 31M (see the solid line in FIG. 1), All of the air cooled by the evaporator 34 bypasses the second branch path 32M and flows into the first branch path 31M. The air flowing in in this way flows out to the downstream portion 3D without being heated by the heater core 35. On the other hand, if the opening degree of the air mixing damper D _M is adjusted in position to open the upstream end of the second minute branch 32M with closing the upstream end of the first minute branch 31M (see the two-dot chain lines in FIG. 1 ), All of the air cooled by the evaporator 34 bypasses the first branch path 31M and flows into the second branch path 32M. The air that has flowed in this way is heated by the heater core 35 and then flows out to the downstream portion 3D.

The downstream portion 3D is connected to the downstream side with respect to the main body portion 3A.
The downstream portion 3D is provided with a vehicle interior passage 30D (lower flow passage) in which blowing portions S1, S2, and S3 (so-called “outlets”) are installed in the compartment 2 (see FIG. 2).
Here, the first lower flow path 31D, the second lower flow path 32D, and the third lower flow path 33D branched into three at the downstream portion 3D are given as examples of the vehicle interior flow path 30D. A first blowout portion S1 is provided in the first lower flow path 31D. Similarly, the first outlet S2 is provided in the second lower channel 32D, and the third outlet S3 is provided in the third lower channel 33D.

The blowout destination of the air flowing through the first lower flow path 31D is set to the window glass W (see FIG. 2, referred to as “DEF” in FIG. 1). The blowout destination of the air flowing through the second lower flow path 32D is set around the occupant's face (referred to as “FACE” in FIG. 1), and the blowout destination of the air flowing through the third lower flow path 33D is the foot of the occupant ( In FIG. 1, it is set to “FOOT”.
The first blowing portion S1 of the first lower flow path 31D is installed below the window glass W, and the window glass W is prevented from being fogged by the air blown from the first blowing portion S1.

The second blowing section S2 of the second lower flow path 32D has a blowing area set in advance in an area where the occupant's face is assumed to be located, and is installed at a location where wind can be blown out toward the blowing area. For example, a plurality of second outlets S <b> 2 are arranged in the middle part in the vertical direction of the passenger compartment 2. In addition, the louver which can be opened and closed manually by the passenger | crew is attached to 2nd blowing part S2.
The third blowing section S3 of the third lower flow path 33D has a blowing area set in advance in an area where the occupant's feet are supposed to be located, and is installed at a location where wind can be blown out toward the blowing area.

Two blower dampers D _V1 and D _V2 are provided at branch points to the three downstream channels 31D, 32D, and 33D in the downstream portion 3D. Specifically, the first blower damper _DV1 is disposed at a branch point to the first lower flow path 31D and the second lower flow path 32D, and the second blower is provided to a branch point to the second lower flow path 32D and the third lower flow path 33D. Damper D _V2 is arranged.
When the opening degree of the blower dampers D _V1 and D _V2 is adjusted to a position where each upstream end of the first lower flow path 31D and the third lower flow path 33D is closed and the upstream end of the second lower flow path 32D is opened ( In the solid line in FIG. 1, air is blown out around the occupant's face.

[1.2. Detailed configuration]
In the downstream portion 3D, in addition to the lower passages 31D, 32D, and 33D in which the blowing portions S1, S2, and S3 face the vehicle compartment 2 as described above, the inner and outer passages communicated with the outside 1 (see FIG. 3). 34D (lower flow path) is provided. That is, in downstream part 3D, it branches into 2 types, vehicle interior flow path 30D, and inside / outside flow path 34D, and these flow paths 30D and 34D are each connected to main-body part 3A.

  As shown in FIG. 3, a chamber 6 into which an object (a shoe is illustrated in FIG. 3) is taken in and out of the interior / external flow path 34 </ b> D is interposed. In the inside / outside channel 34 </ b> D, an air supply channel 35 </ b> D is connected to the upstream side of the chamber 6, and an exhaust channel 36 </ b> D is connected to the downstream side of the chamber 6. The air supply channel 35 </ b> D allows the conditioned air to flow into the chamber 6. The exhaust passage 36 </ b> D exhausts the wind that has flowed out of the chamber 6 to the outside 1 of the vehicle.

As shown in FIG. 1, the inner / outer flow path 34 </ b> D is provided with a third blower damper D _V3 (damper) capable of switching between air flow and blocking thereof. By opening the third blower damper D _V3 is adjusted, the amount of air flowing through the inner and outer flow paths 34D (air volume) is adjusted.
Incidentally, after closing the respective upper end portions of the first downstream passage 31D and the third lower line 33D by the first blower damper D _V1 and the second blower damper D _V2 of the second outlet portion S2 of the second downstream passage 32D If the louver attached to is closed, a flow path into which air flows only into the inner and outer flow paths 34D is formed.

Hereinafter, the configuration of the inner and outer passages 34D will be described in the order of the air supply passage 35D, the chamber 6, and the exhaust passage 36D.
-Supply air flow path-
The air supply channel 35 </ b> D has an upstream end connected to the downstream portion 3 </ b> D and a downstream end connected to the chamber 6. Air that has been conditioned flows from the downstream portion 3D into the air supply passage 35D. The air intake passage 35D, a third blower damper D _V3 described above can be provided. That is, the third blower damper _DV3 is disposed upstream of the chamber 6 (see FIG. 3).

-Chamber-
As shown in FIG. 3, the chamber 6 is disposed in the passenger compartment 2 and has a space (hereinafter referred to as “internal space”) S in which an object can be accommodated. FIG. 2 illustrates the chamber 6 disposed in a region where the passenger's feet can be located.
The chamber 6 is provided with an opening 60 so that an object can be taken in and out. The opening 60 communicates the internal space S of the chamber 6 and the vehicle compartment 2 and functions as an entrance for taking in and out things from the vehicle compartment 2.

Further, the chamber 6 is provided with a lid 61 (lid) that opens and closes the opening 60.
The lid 61 is a lid member that opens and closes the opening 60.
The opening / closing mode of the lid 61 is not limited to a single opening in which one member illustrated in FIG. 2 swings, but may be a double door opening in which two members swing, or as a folding door. The form which folds and open | releases a some member may be sufficient. Alternatively, a configuration may be adopted in which a large number of members connected like an armor door (a so-called “shutter”) are wound up or released.
The shape of the chamber 6 is not limited to the rectangular column shape (cuboid shape) illustrated in FIG. 2, and may be a polygonal column shape or a cylindrical shape, or may be various other shapes.

--Exhaust flow path--
As shown in FIG. 3, the exhaust flow path 36 </ b> D has an upstream end connected to the chamber 6 and a downstream end opened toward the vehicle exterior 1. The wind that flows out from the chamber 6 flows into the exhaust passage 36D, and this wind flows out to the outside 1 of the vehicle. Here, the downstream side of the exhaust passage 36D is provided through the door 12 (here, the side door).

In the exhaust flow path 36D, a check mechanism 7 for preventing a reverse flow of the wind flowing out from the chamber 6 is provided.
The check mechanism 7 is disposed at the downstream end of the exhaust passage 36D. Here, the check mechanism 7 is fitted into the through hole H of the door 12, and the check mechanism 7 is disposed at the end of the exhaust passage 36D in the vehicle width direction.

In the check mechanism 7, a casing 71 in which an opening 70 through which air flowing through the exhaust flow path 36 </ b> D passes is formed and a flap 72 (check valve) that opens and closes the opening 70 is pivotally supported by the casing 71. .
The flap 72 is a normally closed valve that opens the opening 70 if the internal pressure of the exhaust passage 36D is higher than the pressure outside the vehicle 1 and closes the opening 70 otherwise. Note that the flap 72 is opened when the conditioned air is sent to the inner / outer flow path 34D--that is, when the third blower damper _DV3 is opened--otherwise, the flap 72 is closed. You may attach the actuator to do.

[2. Action and effect]
Since the vehicle air conditioner of the present embodiment is configured as described above, the following operations and effects can be obtained.
(1) Since the exhaust flow path 36D for discharging the wind that flows out from the chamber 6 into which the air conditioned by the main body 3A flows is discharged to the outside 1 of the vehicle, the air in the chamber 6 is discharged to the vehicle compartment 2. Can be suppressed. For example, when shoes are accommodated in the chamber 6 and dried, the entry of moisture and odor into the vehicle compartment 2 can be suppressed.

Furthermore, since the air dehumidified by the evaporator 34 or the heater core 35 is sent into the internal space S of the chamber 6, the items stored in the chamber 6 can be efficiently dried. Moreover, if the cold air heat-exchanged by the evaporator 34 is sent into the internal space S, the thing accommodated in the chamber 6 can be cooled or kept cold. On the other hand, if the hot air heat-exchanged by the heater core 35 is sent into the internal space S, it is possible to heat or keep the objects stored in the chamber 6.
As described above, the internal space S of the chamber 6 can be air-conditioned independently of the passenger compartment 2 and can be provided with an air-conditioning function that improves passenger convenience.

Therefore, the internal space S of the chamber 6 can be air-conditioned independently of the vehicle compartment 2 while maintaining the air environment of the vehicle compartment 2. Therefore, passenger comfort can be enhanced.
In addition, an air conditioning function that improves the convenience of passengers can be added by the inner and outer passages 34D while securing the conventional air conditioning function by the passenger compartment passage 30D. From this point as well, passenger comfort can be enhanced.

  (2) Since the exhaust passage 36D is provided with the check mechanism 7 for preventing the reverse flow of the wind flowing out from the chamber 6, it is possible to prevent foreign matters such as rain and dust from entering the chamber 6. Furthermore, since the check mechanism 7 is disposed at the vehicle outer end of the exhaust passage 36D, it is possible to reliably suppress the entry of foreign matter into the exhaust passage 36D. Therefore, the internal space S of the chamber 6 can be kept clean. As a result, aged deterioration of the inner and outer flow paths 34D such as the exhaust flow path 36D and the chamber 6 can be suppressed.

(3) Since the air supply passage 35D for allowing the air conditioned by the main body 3A to flow into the chamber 6 is provided, the restriction on the relative arrangement of the main body 3A and the chamber 6 can be relaxed. It is possible to improve the degree of freedom of design related to the arrangement.
(4) Since the third blowing damper D _V3 which switches between air circulation and the shielding an inside and outside flow paths 34D, it is also possible to adjust the amount of air flowing into the chamber 6. For example, by enhancing the wind flowing into the chamber 6, an additional air conditioning function can be improved. On the other hand, by blocking the air flowing into the chamber 6, it is possible to suppress a decrease in the air volume from the other blowing parts S1, S2, S3. Therefore, the additional air conditioning function can be harmonized without impairing the conventional air conditioning function.

(5) Since the chamber 6 is provided with the lid 61 that opens and closes the opening 60 that communicates with the vehicle compartment 2, the object can be easily accommodated in the internal space S of the chamber 6. It can be easily taken out.
Furthermore, since the lid 61 is a single opening, the opening 60 can be opened and closed with a simple configuration. In addition, if the lid 61 is an open / closed form such as a folding door or an armored door, or a double door open / closed form, it is possible to suppress an area in which the lid 61 can move in the vehicle compartment 2 when the lid 61 is opened as compared with the single-open lid 61. . Therefore, the occupant comfort can be improved.

[II. Others]
The above-described embodiment is merely an example, and there is no intention to exclude various modifications and technical applications that are not explicitly described in this embodiment. Each configuration of the present embodiment can be implemented with various modifications without departing from the spirit thereof. Further, it can be selected as necessary, and can be appropriately combined.

For example, the chamber placement location is not limited to the region where the occupant's feet can be located, and may be set at various locations.
Further, the lid of the chamber may be omitted. For example, you may use a bottomed cylindrical chamber like an umbrella stand. In this case, things can be taken in and out of the internal space of the chamber from the upper opening, and a simple configuration can be achieved.

  Or you may provide the damper which can switch the distribution | circulation and interruption | blocking of the air in each of a 1st lower flow path, a 2nd lower flow path, and a 3rd lower flow path. When the air flow is blocked in all of the first lower flow path, the second lower flow path, and the third lower flow path by such a damper, the air conditioned wind can be freely moved without manually closing the louver in the second downstream portion. It is possible to strengthen the wind that is sent only to the flow path and blows out from the outlet of the free flow path. Thereby, a passenger | crew's convenience can further be improved.

  In addition, the vehicle on which the air conditioner is mounted may be a hybrid electric vehicle using an electric motor as a drive source in addition to the engine, or may be an electric vehicle using only an electric motor as a drive source. In these hybrid electric vehicles and air conditioners mounted on electric vehicles, an electric heater is used for the heater core, and an electric compressor is used for the compressor.
