To provide a vehicular air-conditioning unit which, when independently adjusting each of the temperature of air blown into a driver's seat-side space and the temperature of air blown into a front passenger seat-side space, can perform the temperature adjustment of the air while suppressing heat loss.SOLUTION: In an inside air double-suction mode, the inside air of a driver's seat side flows from a driver's seat-side space 901 into a driver's seat-side suction space 16f, and the inside air of a front passenger seat side flows from a front passenger seat-side space 902 into a front passenger seat-side suction space 16k. A partition plate 28 in an air-conditioning case 16 serves as a partition between the driver's seat-side suction space 16f and the front passenger seat-side suction space 16k. As a result, it is possible to inhibit, by the partition plate 28, the air in the suction space 16f and the air in the suction space 16k from exchanging heat with each other. Accordingly, when independently adjusting each of the temperature of air blown from an air-conditioning unit 10 into the driver's seat-side space 901 and the temperature of air blown therefrom into the front passenger seat-side space 902, it is possible to perform the temperature adjustment of the air while suppressing heat loss.SELECTED DRAWING: Figure 2

Description

  The present invention relates to a vehicle air conditioning unit that performs air conditioning in a cabin space.

  As a vehicle air conditioning unit of this type, a car air conditioner described in, for example, Patent Document 1 is conventionally known. The automotive air conditioner described in Patent Document 1 includes an evaporator for cooling air, a heater core for heating the air, and a mix door provided on the upstream side of the heater core in an air conditioning case.

  And in the air conditioning apparatus for motor vehicles, the ratio of the air volume of the air which flows to a heater core among the air which flowed out out of an evaporator, and the air volume of the air which bypasses a heater core is adjusted by operation of a mix door. By adjusting the air volume ratio, the temperature of the conditioned air blown out to the passenger compartment space is adjusted.

JP-A-11-348536

  There is a vehicle air conditioning unit that can independently adjust the temperature of air blown out to the driver's seat side space in the passenger compartment space and the temperature of air blown out to the passenger seat side space in the passenger compartment space. . Such a vehicle air conditioning unit capable of adjusting the air temperature independently on the driver's seat side and the passenger seat side, for example, in the automotive air conditioner of Patent Document 1, has an air passage downstream of the heater core in the vehicle width direction. It has the same configuration as the configuration divided into right and left. That is, in the vehicle air conditioning unit, the air passages on the downstream side with respect to the heater core are formed as independent air passages independent of each other on the left and right of the vehicle width direction. The air passage upstream of the heater core in the vehicle air conditioning unit is generally the same as that of the automotive air conditioner of Patent Document 1.

  In such a vehicle air conditioning unit, after the temperature adjustment in the heater core, air flows through independent air passages independent of each other, so the temperature of the air blown out to the driver's seat side space and the air onto the passenger side side The temperature of the air to be fed can be adjusted independently.

  However, in the above-described vehicle air conditioning unit, as with the automotive air conditioner of Patent Document 1, there is one suction port from the cabin space, so the space on the driver's seat side and the space on the passenger seat side It was considered wasteful to adjust the temperature separately.

  Furthermore, even if the suction port opened in the space on the driver's seat side and the suction port opened in the space on the passenger seat side are provided, the air flowing in from both suction ports flows into the independent air passage. It is assumed that they will exchange heat with each other. If so, it is also conceivable that the heat exchange causes a heat loss (in other words, a heat loss). As a result of the inventor's detailed examination, the above was found out.

  In view of the above-mentioned point, the present invention suppresses the heat loss in independently adjusting the temperature of the air blown out to the driver's seat side space and the temperature of the air blown out to the passenger seat side space. An object of the present invention is to provide a vehicle air conditioning unit capable of adjusting the temperature of air.

In order to achieve the above object, the vehicle air conditioning unit according to claim 1 is:
The temperature of the air blown out to the space (901) on the driver's seat (11) side of the compartment space (90) and the temperature of the air blown out to the space (902) on the passenger seat (12) A vehicle air conditioning unit configured to be able to adjust the temperature independently.
Driver's seat side suction port (16a) which opens to the space of driver's seat side, driver's seat side suction space (16f) where air flows in from the space of driver's seat side via the driver's seat side suction port, its driver's seat side suction space Air flows from the driver's seat side air passage (16h) through which the air flowing from it flows, the passenger's seat side inlet (16c) opening to the passenger's seat side, and the passenger's seat side from the passenger's seat side An air conditioning case in which a passenger seat side suction space (16k) and a passenger seat side ventilation path (16n) separated from the driver seat side 16) and
Provided in the air conditioning case, sucks air from the driver's side suction space and sends the sucked air to the driver's side ventilation path, and sucks air from the passenger's seat side suction space and flows the sucked air to the passenger's side ventilation path A blower fan (224),
A partition (28, 30, 32) is provided in the air conditioning case and partitions the space between the driver's seat side suction space and the passenger's seat side suction space.

  In this manner, the air flowing into the driver's seat-side suction space from the driver's seat-side space and the air flowing into the passenger seat-side suction space from the passenger seat-side space exchange heat with each other. It is possible to suppress. Therefore, in adjusting the temperature of the air blown into the driver's seat space and the temperature of the air blown into the passenger seat space independently, the heat loss is suppressed to adjust the temperature of the air. Is possible.

In the present embodiment, the driver's seat 11 is disposed on the right side of the passenger seat 12 in the vehicle width direction DR2.

  As shown in FIGS. 1 and 2, the air conditioning unit 10 according to this embodiment includes an air conditioning case 16, a filter 18, an evaporator 20, a blower 22, a plurality of doors 24, 25 and 26, a partition plate 28, and not shown. The heater core of the Each door 24, 25, 26 which the air conditioning unit 10 has is operated, for example, by an actuator controlled by an electronic control unit that performs air conditioning control.

  The air conditioning case 16 is a resin member that forms the outer shell of the vehicle air conditioning unit 10. The air-conditioning case 16 is provided with a driver's seat-side suction port 16a, a driver's seat-side outlet 16b, a passenger's seat-side inlet 16c, and a passenger's seat-side outlet 16d as communication holes for communicating the inside and outside of the air-conditioning case 16 There is.

  The driver's seat side suction port 16 a and the driver's seat side outlet 16 b are open to the driver's seat side space 901. The driver's seat side internal air which is air of the driver's seat side space 901 is sucked into the air conditioning case 16 through the driver's seat side inlet port 16a. Although various arrangements are possible for the driver's seat side suction port 16 a, the driver's seat side suction port 16 a of the present embodiment is opened in the vicinity of the feet of the occupant seated on the driver's seat 11.

  Further, the air whose temperature is adjusted after passing through the driver seat side fan 221 of the blower 22 in the air conditioning case 16 is blown out from the inside of the air conditioning case 16 to the driver seat side space 901 through the driver seat outlet 16 b. In the present embodiment, for example, the driver's seat side outlet 16b is divided into a plurality of outlets such as a driver's seat side face outlet, a driver's seat side defroster outlet, and a driver's seat side foot outlet. . The driver's seat side face outlet is an outlet that blows air toward the face or chest of the occupant seated in the driver's seat 11. The driver's seat side defroster outlet is an outlet for blowing air toward the window glass on the driver's seat 11 side among the window glass on the front of the vehicle. The driver's seat side foot outlet is an outlet that blows air toward the feet of the occupant seated in the driver's seat 11.

  The passenger side suction port 16 c and the passenger side air outlet 16 d are open to the passenger side space 902. Passenger-side internal air, which is air of the passenger-side space 902, is drawn into the air conditioning case 16 through the passenger-side suction port 16c. Although various arrangements are possible for the passenger side suction port 16c, the passenger side suction port 16c of the present embodiment is opened in the vicinity of the feet of the occupant seated in the passenger seat 12.

  Further, the air whose temperature is adjusted after passing through the passenger side fan 222 of the blower 22 in the air conditioning case 16 is blown out from the inside of the air conditioning case 16 into the passenger side space 902 through the passenger side air outlet 16 d. In the present embodiment, for example, the passenger side air outlet 16d is divided into a plurality of air outlets such as a passenger side face air outlet, a passenger side defroster air outlet, and a passenger side foot air outlet. . The front passenger side face air outlet is an air outlet which blows air toward the face or chest of the occupant seated in the front passenger seat 12. The passenger side defroster air outlet is an air outlet that blows air toward the window glass on the side of the passenger seat 12 among the window glass on the front of the vehicle. The passenger side foot blower outlet is a blower outlet that blows air toward the feet of the occupant seated in the passenger seat 12.

  Inside the air conditioning case 16, a driver's seat side suction space 16f, a driver's seat side fan space 16g, a driver's seat side ventilation passage 16h, an outside air introduction passage 16j, a passenger side suction space 16k, a passenger side fan space 16m and a passenger seat A side air passage 16n is formed.

  The driver's seat side suction space 16f is provided on the air flow upstream side with respect to the filter 18, and the driver's seat side suction port 16a is connected to the driver's seat side suction space 16f. Therefore, air flows into the driver's seat side suction space 16 f from the driver's seat side space 901 via the driver's seat side suction port 16 a.

  Here, between the driver's seat side suction port 16a and the driver's seat side suction space 16f, a driver's seat side entrance door 24 that opens and closes is provided. When the driver's seat side inlet door 24 is opened, air can flow into the driver's seat side suction space 16f from the driver's seat side suction port 16a. Conversely, when the driver's seat side inlet door 24 is closed, the communication between the driver's seat side suction port 16a and the driver's seat side suction space 16f is cut off, and the driver's seat side suction port 16a to the driver's seat side suction space 16f Air flow is blocked.

  The driver's seat side fan space 16 g is provided on the downstream side of the air flow with respect to the evaporator 20. Further, the evaporator 20 is provided downstream of the filter 18 with respect to the air flow. Therefore, the air of the driver's seat side suction space 16f passes through the filter 18 and the evaporator 20 in order and then flows into the driver's seat side fan space 16g.

  The driver's seat side air passage 16h is provided downstream of the driver's seat fan space 16g in the airflow direction. Therefore, air flows from the driver's seat side suction space 16f into the driver's seat side air passage 16h via the driver's seat side fan space 16g. And in the driver's seat side ventilation path 16h, the air which flowed in from the driver's seat side suction space 16f flows toward the air flow downstream end of the driver's seat side ventilation path 16h like arrow F 2 d. The air flow downstream end of the driver's seat side ventilation passage 16h is connected to the driver's seat side outlet 16b. That is, the driver's seat side ventilation path 16 h is an air passage through which the air blown out to the driver's seat side space 901 flows.

  The air conditioning case 16 has a duct-like outside air introducing part 163, and the outside air introducing passage 16 j is formed inside the outside air introducing part 163 of the air conditioning case 16. The outside air introducing passage 16 j is an air passage for introducing the outside air which is the air outside the cabin space 90.

  Therefore, the air flow upstream end of the outside air introduction passage 16j is connected to the front passenger side outside air introduction port opened to the outside of the vehicle by, for example, a cowl on the front passenger side. On the other hand, the air flow downstream end 16p of the outside air introduction passage 16j is connected to the passenger side suction space 16k. More specifically, the outside air introduction passage 16j is connected to the passenger side suction space 16k of the driver side suction space 16f and the passenger side suction space 16k, but connected to the driver side suction space 16f It has not been.

  The passenger seat side suction space 16k is provided on the air flow upstream side with respect to the filter 18, and the outside air introduction passage 16j and the passenger seat side suction port 16c are respectively connected to the passenger seat side suction space 16k. Accordingly, air flows from the passenger seat side space 902 into the passenger seat side suction space 16k via the passenger seat side suction port 16c. Further, the outside air flows into the passenger side suction space 16k from the outside air introduction passage 16j.

  Here, an inside / outside air door 25 and a passenger side entrance door 26 are provided between each of the outside air introduction passage 16j and the passenger side suction port 16c and the passenger side suction space 16k. Further, the inside / outside air door 25 is provided upstream of the passenger side entrance door 26 in the air flow direction.

  The inside and outside air door 25 is, for example, a pivoting door, and opens and closes the front passenger seat side suction port 16c and the air flow downstream end 16p of the outside air introduction passage 16j. Specifically, the inside / outside air door 25 operates so as to decrease the opening degree of the air flow downstream end 16p of the outside air introducing passage 16j as the opening degree of the front passenger seat side suction port 16c is increased. That is, when closing the front passenger seat side suction port 16c, the inside / outside air door 25 maximizes the opening degree of the air flow downstream end 16p of the outside air introduction passage 16j. Conversely, when closing the air flow downstream end 16p of the outside air introduction passage 16j, the inside / outside air door 25 maximizes the opening degree of the front passenger side suction port 16c.

  The passenger side entrance door 26 is a door that opens and closes. When the front passenger side inlet door 26 is opened, air can flow into the front passenger side suction space 16k from one or both of the front passenger side suction port 16c and the outside air introduction passage 16j. Conversely, when the front passenger seat side inlet door 26 is closed, communication between each of the outside air introduction passage 16j and the front passenger seat side suction port 16c and the front passenger seat side suction space 16k is cut off. That is, in that case, air can not flow into the passenger side suction space 16k from any of the outside air introduction passage 16j and the passenger side suction port 16c.

  The passenger side fan space 16m is provided downstream of the evaporator 20 with respect to the air flow. Therefore, the air of the passenger side suction space 16k passes through the filter 18 and the evaporator 20 in order and then flows into the passenger side fan space 16m.

  The passenger side ventilation passage 16n is provided downstream of the air flow with respect to the passenger side fan space 16m. Therefore, air flows from the passenger side suction space 16k into the passenger side ventilation passage 16n via the passenger side fan space 16m. Then, in the passenger side ventilation passage 16n, the air flowing in from the passenger side suction space 16k flows toward the air flow downstream end of the passenger side ventilation passage 16n as indicated by an arrow F2p. The air flow downstream end of the front passenger side ventilation passage 16n is connected to the front passenger side air outlet 16d. That is, the passenger side ventilation path 16 n is an air passage through which the air blown out to the passenger side space 902 flows.

  Further, the air conditioning case 16 has a first partition wall portion 161 and a second partition wall portion 162. The first partition portion 161 and the second partition portion 162 have a plate shape whose thickness direction is in the vehicle width direction DR2. The first partition wall portion 161 divides the driver seat side fan space 16g and the passenger seat side fan space 16m, and the driver seat side ventilation passage 16h and the passenger seat side ventilation passage 16n. Therefore, the passenger side ventilation path 16n is a ventilation path separated from the driver side ventilation path 16h.

  Further, the second partition wall portion 162 includes an air passage from the driver's seat side filter portion 181 of the filter 18 to the driver's seat side heat exchange portion 201 of the evaporator 20 and a passenger seat side filter portion 182 of the filter 18 from the evaporator 20. The air passage to the passenger side heat exchange unit 202 is partitioned.

  The filter 18 is made of a material through which air can pass, such as a non-woven fabric, for example. The filter 18 captures foreign matter in the air passing through the filter 18 and filters the air. The filter 18 is housed in the air conditioning case 16. The filter 18 is provided over substantially the entire width in the air conditioning case 16 in the vehicle width direction DR2, and includes a driver's seat side filter portion 181 and a passenger's seat side filter portion 182.

  The driver's seat side filter unit 181 is provided in an air passage from the driver's seat side suction space 16f to the driver's seat side fan space 16g. Therefore, the driver's seat side filter section 181 filters the air flowing out from the driver's seat side suction space 16f.

  Further, the passenger seat side filter portion 182 is provided in an air passage from the passenger seat side suction space 16k to the passenger seat side fan space 16m. Therefore, the front passenger side filter unit 182 filters the air flowing out from the front passenger side suction space 16k.

  The evaporator 20 is a cooling heat exchanger that cools the air passing through the evaporator 20. The evaporator 20, together with a compressor, a condenser, and an expansion valve (not shown), constitutes a known refrigeration cycle apparatus for circulating a refrigerant for air conditioning which is a heat medium. The evaporator 20 exchanges heat between the air passing through the evaporator 20 and the refrigerant, and the heat exchange evaporates the refrigerant and cools the air.

  The evaporator 20 is housed in the air conditioning case 16. The evaporator 20 is provided over substantially the entire width in the air conditioning case 16 in the vehicle width direction DR2, and includes a driver's seat side heat exchange unit 201 and a passenger's seat side heat exchange unit 202.

  The driver's seat side heat exchange unit 201 is provided in an air passage from the driver's seat side suction space 16f to the driver's seat side fan space 16g. And the driver's seat side heat exchange part 201 is provided on the air flow downstream side with respect to the driver's seat side suction space 16f, specifically speaking, on the air flow downstream side with respect to the driver's seat side filter part 181. Accordingly, the driver's seat side heat exchange unit 201 exchanges heat with the air flowing out of the driver's seat side suction space 16 f by exchanging heat with the refrigerant, and then flows the air to the driver's seat side fan space 16 g.

  In addition, the passenger seat side heat exchange unit 202 is provided in an air passage from the passenger seat side suction space 16k to the passenger seat fan space 16m. The passenger seat side heat exchange unit 202 is provided on the air flow downstream side with respect to the passenger seat side suction space 16k, specifically, on the air flow downstream side with respect to the passenger seat side filter unit 182. Accordingly, the passenger side heat exchange unit 202 exchanges the heat flowing between the air flowing out from the passenger side suction space 16k and the refrigerant to cool the air, and then flows the air to the passenger side fan space 16m.

  The blower 22 has a driver side fan 221, a passenger side fan 222, and a fan motor 223. The driver seat side fan 221, the passenger seat side fan 222 and the fan motor 223 are provided in the air conditioning case 16.

  The driver's seat side fan 221 and the passenger's seat side fan 222 are configured as centrifugal fans, and are rotationally driven by a fan motor 223. The driver's seat side fan 221 is disposed in the driver's seat side fan space 16g. That is, the driver's seat side heat exchange unit 201 of the evaporator 20 is disposed on the upstream side of the air flow with respect to the driver's seat side fan 221. Therefore, the driver's seat side fan 221 rotates to suck in the air passing through the driver's seat side heat exchange unit 201 from the driver's seat side suction space 16f, and flows the sucked air to the driver's seat side ventilation passage 16h.

  The passenger side fan 222 is disposed in the passenger side fan space 16 m. That is, the passenger side heat exchange unit 202 of the evaporator 20 is disposed on the upstream side of the air flow with respect to the passenger side fan 222. Accordingly, the passenger side fan 222 rotates to suck in the air passing through the passenger side heat exchange section 202 from the passenger side suction space 16k, and causes the sucked air to flow to the passenger side ventilation passage 16n. The driver's seat side fan 221 and the passenger's seat side fan 222 collectively function as a blower fan portion 224 for blowing air in the air conditioning case 16.

  The partition plate 28 is provided in the air conditioning case 16 between the driver's seat side suction space 16 f and the passenger's seat side suction space 16 k. The partition plate 28 is a partitioning portion that partitions between the driver's seat side suction space 16f and the passenger's seat side suction space 16k.

  The partition plate 28 is made of an elastic member such as rubber or elastomer which elastically deforms, and has a plate shape with the vehicle width direction DR2 as a thickness direction. That is, the partition plate 28 faces the driver's seat side suction space 16f on one side in the vehicle width direction DR2, and faces the passenger's seat side suction space 16k on the other side in the vehicle width direction DR2. In other words, the driver's side suction space 16f, the partition plate 28 and the passenger's seat side suction space 16k are from the one side in the vehicle width direction DR2, the driver's seat side suction space 16f, the partition plate 28, the passenger's seat side suction space 16k It is arranged in order of.

  And as shown to FIG. 3 and FIG. 4, the partition plate 28 has the structure which can cancel releasing between driver's seat side suction space 16f and passenger seat side suction space 16k. In short, the partition plate 28 can release the partitioning of the suction spaces 16f and 16k from each other by elastic deformation of the partition plate 28.

  In detail, the partition plate 28 has one end of the partition plate 28 as a fixed end 281 fixed to the air conditioning case 16. The partition plate 28 has the other end of the partition plate 28 as a free end 282 which is not restrained by the air conditioning case 16. Therefore, the partition plate 28 can be elastically deformed and bent so as to move the free end 282 in the vehicle width direction DR2 as shown in FIGS. 3 and 4.

  From such a configuration, in the free state in which no external force is applied to the partition plate 28, as shown in FIG. 2, the partition plate 28 is not elastically deformed. Therefore, the partition plate 28 in the free state divides the space between the driver's seat side suction space 16f and the passenger's seat side suction space 16k, and separates the driver's seat side suction space 16f from the passenger's seat side suction space 16k.

  On the other hand, in an elastic deformation state in which an external force is applied to the partition plate 28 and the partition plate 28 is elastically deformed, as shown in FIG. 3 and FIG. 4, the partition plate 28 bends to bend. Therefore, the partition plate 28 in the elastically deformed state releases the partition between the driver's seat side suction space 16f and the passenger's seat side suction space 16k by bending the partition plate 28, and the respective suction spaces 16f, 16k Communicate with each other.

  Since the partition plate 28 faces both the driver's seat side suction space 16f and the passenger seat side suction space 16k, for example, the driver's seat side suction space 16f and the passenger seat's side suction can be used as a factor for bending the partition plate 28 The pressure difference with the space 16k can be mentioned. Specifically, when the partition plate 28 bends according to the air pressure difference, the free end 282 is moved to the suction space on the side where the air pressure is lower among the driver side suction space 16f and the passenger side suction space 16k. Flex to make me Then, the partition plate 28 is elastically deformed so as to be bent more largely as the air pressure difference between the driver's seat side suction space 16f and the passenger's seat side suction space 16k becomes larger.

  Next, a plurality of air suction modes of the air conditioning unit 10 will be described. In the present embodiment, the air suction mode of the air conditioning unit 10 is alternatively switched to the room air suction mode, the room air suction mode, the driver side room air suction mode, and the passenger side room air intake mode. In the following description of the air suction mode, it is assumed that the fans 221 and 222 of the blower 22 are rotationally driven. The same applies to the description of the air suction mode in the second embodiment and later described later.

  As shown in FIG. 2, in the room air suction mode, the driver's seat side room air and the passenger seat side room air are drawn into the air conditioning unit 10, respectively. On the other hand, outside air is not drawn into the air conditioning unit 10 in this room air suction mode. To that end, the driver's side entry door 24 and the passenger's side entry door 26 are opened. Then, the inside / outside air door 25 opens the front passenger seat side suction port 16c and closes the air flow downstream end 16p of the outside air introduction passage 16j.

  By the operation of the doors 24, 25 and 26, the driver's seat side internal air flows from the driver's seat side space 901 into the driver's seat side suction space 16f via the driver's seat side suction port 16a as shown by arrow F1d. In addition, passenger's seat side inside air flows from the passenger's seat side space 902 to the passenger's seat side suction space 16k via the passenger's seat side suction port 16c as shown by arrow F1 p.

  At this time, the air pressure in the driver's seat side suction space 16f and the air pressure in the passenger's seat side suction space 16k have substantially the same size, so the partition plate 28 does not bend. That is, the partition plate 28 maintains a state in which the driver's seat side suction space 16f and the passenger's seat side suction space 16k are partitioned, and the air between the driver's seat side suction space 16f and the passenger's seat side suction space 16k Stop the circulation. Note that the air flow does not have to be completely blocked between the two suction spaces 16f and 16k, and some air movement may be permitted.

  The driver's seat side internal air that has flowed into the driver's seat side suction space 16 f passes the driver's seat side filter portion 181 and the driver's seat side heat exchange portion 201 in order as shown by arrow F 1 d, and is cooled by the driver's seat side heat exchange portion 201. Then, the driver's seat side fan 221 sucks the air. Then, the driver's seat side internal air is blown out from the driver's seat side fan 221 as boosted air and flows to the driver's seat side ventilation path 16h.

  In addition, passenger-side inside air flowing into the passenger-side suction space 16k passes through the passenger-side filter unit 182 and the passenger-side heat exchange unit 202 in this order as indicated by arrow F1p, and the passenger-side heat exchange unit 202 After being cooled, the air is sucked into the passenger side fan 222. Then, the passenger side interior air is blown out from the passenger side fan 222 as pressurized air, and flows to the passenger side ventilation path 16n.

  The driver's seat side air flowing into the driver's seat side ventilation passage 16h is temperature-adjusted by the driver's seat side air mix door provided in the middle of the driver's seat side ventilation passage 16h, and then the driver's seat side outlet 16b of FIG. It is blown out to the driver's seat side space 901 via the same. The temperature adjustment is carried out by the ratio of the air volume passing through the driver seat side portion of the heater core provided in the middle of the driver seat side ventilation path 16 h to the air volume flowing around the driver seat side portion of the heater core. It is done by being adjusted by the air mix door. The air that has passed through the driver's seat side of the heater core (i.e., warm air) and the air that has bypassed the driver's seat side of the heater core (i.e., cold air) flow through the driver's seat side outlet 16b. The flow is mixed upstream.

  The passenger side internal air flowing into the passenger side ventilation passage 16n in FIG. 2 is temperature-controlled by the passenger side air mix door provided in the middle of the passenger side ventilation passage 16n, and then the passenger seat in FIG. The air is blown out to the passenger side space 902 via the side air outlet 16d. The temperature control by the passenger side air mix door is the same as the temperature control by the driver side air mix door described above. The passenger side air mix door and the driver side air mix door operate independently of each other.

  By such left and right temperature independent control, the temperature of the air blown out of the driver's seat side space 901 and the temperature of the air blown out of the passenger's seat side space 902 are separately adjusted to arbitrary temperatures.

  As shown in FIG. 3, the outside air is sucked into the air conditioning unit 10 in the outside air suction mode. On the other hand, in the outside air suction mode, neither the driver's seat side nor the passenger side inside air is sucked into the air conditioning unit 10. To that end, the driver's side entry door 24 is closed and the passenger's side entry door 26 is opened. Then, the inside / outside air door 25 opens the air flow downstream end 16p of the outside air introduction passage 16j and closes the front passenger seat side suction port 16c.

  By the operation of the doors 24, 25, 26, the outside air flows into the passenger side suction space 16k through the outside air introduction passage 16j. At this time, the driver's seat side fan 221 sucks air despite the fact that the driver's seat side entrance door 24 is closed, so the air pressure of the driver's side suction space 16f is lower than the air pressure of the passenger's seat side suction space 16k. Become. Therefore, the partition plate 28 is bent and bent so that the free end 282 moves to the driver's seat side suction space 16 f side. And the partition plate 28 makes it connect between the driver's seat side suction space 16f and the passenger seat side suction space 16k by bending like that.

  Since the partition plate 28 establishes communication between the driver's seat side suction space 16f and the passenger's seat side suction space 16k, the outside air having flowed into the passenger's seat side suction space 16k is divided into two parts and flows. That is, the outside air of the passenger side suction space 16k flows to the passenger side fan space 16m as indicated by the arrow F3p, and also flows to the driver's seat side suction space 16f as indicated by the arrow F3d. The subsequent air flow is the same as in the above-mentioned internal air intake mode.

  As described above, in the outside air suction mode, air can be introduced not only to the passenger side ventilation passage 16n but also to the driver side ventilation passage 16h by the elastic deformation of the partition plate 28.

  As shown in FIG. 4, in the driver's seat side ambient air suction mode, the driver's seat side ambient air is sucked into the air conditioning unit 10. On the other hand, neither the outside air nor the passenger side inside air is drawn into the air conditioning unit 10 in the driver's side inside air intake mode. To that end, the passenger side entry door 26 is closed and the driver's side entry door 24 is opened. Since the passenger side entrance door 26 is closed, the inside / outside air door 25 may be at any door position, but in the present embodiment, the inside / outside air door 25 is the air flow downstream end 16p of the outside air introduction passage 16j. While closing the front passenger side suction port 16c.

  Due to the operation of the doors 24 and 26, the driver's seat side internal air flows from the driver's seat side space 901 into the driver's seat side suction space 16f via the driver's seat side inlet port 16a. At this time, the passenger side fan 222 sucks air despite the fact that the passenger side inlet door 26 is closed, so the air pressure in the passenger side suction space 16k is lower than the air pressure in the driver side suction space 16f. Become. Therefore, the partition plate 28 bends and bends so that the free end 282 moves to the passenger side suction space 16k side. And the partition plate 28 makes it connect between the driver's seat side suction space 16f and the passenger seat side suction space 16k by bending like that.

  Since the partition plate 28 establishes communication between the driver's seat side suction space 16f and the passenger's seat side suction space 16k, the driver's seat side internal air that has flowed into the driver's seat side suction space 16f is divided into two hands and flows. That is, the outside air of the driver's seat side suction space 16f flows to the driver's seat side fan space 16g as indicated by the arrow F4d, and also flows to the passenger's seat side suction space 16k as indicated by the arrow F4p. The subsequent air flow is the same as in the above-mentioned internal air intake mode.

  As described above, in the driver's seat side inside air suction mode, air can be introduced not only to the driver's seat side ventilation passage 16 h but also to the passenger's seat side ventilation passage 16 n by elastically deforming the partition plate 28.

  As shown in FIG. 5, in the passenger side internal air suction mode, the passenger side internal air is drawn into the air conditioning unit 10. On the other hand, neither the outside air nor the driver's side inside air is drawn into the air conditioning unit 10 in the passenger side inside air suction mode. To that end, the driver's side entry door 24 is closed and the passenger's side entry door 26 is opened. Then, the inside / outside air door 25 opens the front passenger seat side suction port 16c and closes the air flow downstream end 16p of the outside air introduction passage 16j.

  With the operation of the doors 24, 25 and 26, the passenger side interior air flows from the passenger side space 902 into the passenger side suction space 16k via the passenger side suction port 16c. At this time, the driver's seat side fan 221 sucks air despite the fact that the driver's seat side entrance door 24 is closed, so the air pressure of the driver's side suction space 16f is lower than the air pressure of the passenger's seat side suction space 16k. Become. Therefore, the partition plate 28 is bent and bent so that the free end 282 moves to the driver's seat side suction space 16 f side. And the partition plate 28 makes it connect between the driver's seat side suction space 16f and the passenger seat side suction space 16k by bending like that.

  Since the partition plate 28 establishes communication between the driver's seat side suction space 16f and the passenger's seat side suction space 16k, the passenger's seat side internal air that has flowed into the passenger's seat side suction space 16k is divided into two hands and flows. That is, the passenger side internal air of the passenger side suction space 16k flows to the passenger side fan space 16m as indicated by the arrow F5p, and also flows to the driver's side suction space 16f as indicated by the arrow F5d. The subsequent air flow is the same as in the above-mentioned internal air intake mode.

  As described above, in the passenger side side internal air suction mode, air can be introduced not only to the passenger side ventilation path 16n but also to the driver side ventilation path 16h by the elastic deformation of the partition plate 28.

  As described above, according to the present embodiment, as shown in FIG. 1 and FIG. 2, in the inside air suction mode, the driver's seat side inside air is driven from the driver's seat side space 901 via the driver's seat side intake port 16 a. It flows into the seat side suction space 16f. At the same time, passenger-side inside air flows from the passenger-side space 902 into the passenger-side suction space 16k via the passenger-side suction port 16c. And the partition plate 28 as a partition part provided in the inside of the air-conditioning case 16 divides between the driver's seat side suction space 16f and the passenger seat side suction space 16k. Therefore, the partition plate 28 can suppress heat exchange between the driver's seat side interior air of the driver's seat side suction space 16 f and the passenger seat side inside air of the passenger side suction space 16 k. Therefore, in adjusting the temperature of the air blown out from the air conditioning unit 10 to the driver's seat side space 901 and the temperature of the air blown out to the passenger's seat side space 902 independently, the temperature adjustment of the air is heat It is possible to do with less loss.

  For example, the air conditioning unit which eliminated the partition plate 28 from the air conditioning unit 10 of this embodiment is shown by FIG. 6 as an air conditioning unit 80 of a comparative example. In the room air suction mode, as described above, the temperatures of the air blown into both spaces 901 and 902 are adjusted independently, so the temperature of the driver's side room air flowing into the driver's side suction space 16f and the passenger's side suction A temperature difference may occur between the temperature of the passenger-side interior air flowing into the space 16k. When a temperature difference occurs as such, in the air conditioning unit 80 of the comparative example, the space between the driver's seat side suction space 16f and the passenger's seat side suction space 16k is opened, so the driver's seat of the driver's seat side suction space 16f The side room air and the passenger side room air of the passenger side suction space 16k exchange heat with each other.

  On the other hand, in the air conditioning unit 10 of the present embodiment, as shown in FIG. 2, the partition plate 28 suppresses the heat exchange of air between the driver's seat side suction space 16 f and the passenger's seat side suction space 16 k. Therefore, it is possible to reduce the heat loss (in other words, the heat loss) due to the heat exchange of air between the two suction spaces 16f and 16k. In short, as described above, it is possible to control the temperature of the air while suppressing the heat loss. In other words, it is possible to adjust the temperature of the blowout air to the driver's seat side space 901 and the blowout air to the passenger's seat side space 902 independently of each other with the heat loss reduced.

  Further, according to the present embodiment, as shown in FIGS. 3 to 5, the partition plate 28 has a configuration capable of releasing the division between the driver's seat side suction space 16 f and the passenger's seat side suction space 16 k. doing. Therefore, the air suction mode of the air conditioning unit 10 is switched to various modes such as the outside air suction mode, the driver's seat side air intake mode, and the passenger side air intake mode of this embodiment as well as the inside air both suction mode. It is possible. In short, it is possible to appropriately flow air from the driver's side suction space 16f to the assistant's seat side suction space 16k and to flow air from the passenger's seat side suction space 16k to the driver's seat side suction space 16f.

  In particular, if the air conditioning case 16 is configured such that the outside air introduction passage 16j is connected to one of the passenger side suction space 16k and the driver side suction space 16f, the outside air is introduced to both suction spaces 16f and 16k. It has the merit of being able to

  For example, in the present embodiment, the outside air is introduced from the side of the passenger seat 12 in the vehicle width direction DR2, and the outside air introducing passage 16j for introducing the outside air is connected to the passenger side suction space 16k. Therefore, in the outside air suction mode, as shown in FIG. 3, outside air from the outside air introduction passage 16j is introduced into the passenger side suction space 16k, but the outside air can be introduced only by the passenger side heat exchange portion 202 of the evaporator 20. It is also possible to ventilate the driver's side heat exchange section 201. In short, it is possible to ventilate the outside air introduced into the passenger side suction space 16k to the entire surface of the evaporator 20.

  Further, according to the present embodiment, as shown in FIGS. 3 to 5, the partition plate 28 is elastically deformed so that the larger the pressure difference between the driver side suction space 16f and the passenger side suction space 16k, the larger the deflection. It is comprised by the elastic member which deform | transforms. Then, the partition plate 28 releases the partition between the driver's seat side suction space 16f and the passenger's seat side suction space 16k by bending the partition plate 28, and the driver's seat side suction space 16f and the passenger's seat side Communication with the suction space 16k is established. Therefore, switching between partitioning the driver's seat side suction space 16 f and the passenger seat side suction space 16 k and releasing the partition is performed by the partition plate 28 without providing a drive source such as an actuator. Is possible.

  Further, according to the present embodiment, as shown in FIG. 3, the air conditioning case 16 is formed with the outside air introduction passage 16 j for introducing the outside air. The outside air introduction passage 16j is connected to a front passenger seat side suction space 16k which is one of a driver seat side suction space 16f and a front passenger seat side suction space 16k. The outside air introduction passage 16j is not connected to the driver's side suction space 16f, which is the other of the driver's side suction space 16f and the passenger's seat side suction space 16k. Specifically, in the driver's side suction space 16f, when the partition plate 28 releases the partition between the driver's side suction space 16f and the passenger's side suction space 16k, the outside air introduction passage 16j is on the passenger side It is connected via the suction space 16k.

  Therefore, the outside air introduction passage 16 j can be formed with a simple structure. At the same time, external air can be introduced to the driver's side suction space 16f by utilizing the configuration of the partition plate 28 which can release the division between the driver's side suction space 16f and the passenger's seat side suction space 16k. The air conditioning unit 10 can be configured as follows.

Second Embodiment
Next, a second embodiment will be described. In the present embodiment, points different from the first embodiment described above will be mainly described. In addition, the same or equivalent parts as those of the above-described embodiment will be described by omitting or simplifying them. The same applies to the description of the embodiments described later.

  As shown in FIG. 7, the air conditioning unit 10 of the present embodiment includes a partition door 30 that can be opened and closed, instead of the partition plate 28 of the first embodiment. In this respect, the present embodiment is different from the first embodiment.

  Concretely, since the partition door 30 of this embodiment is replaced with the partition plate 28 (refer FIG. 2) of 1st Embodiment, it is the driver's seat side suction space 16f and a passenger seat similarly to the partition plate 28 It is provided in the air-conditioning case 16 as a partition part which divides between the side suction space 16k. Therefore, the partition door 30 is provided in the air conditioning case 16 between the driver's seat side suction space 16f and the passenger's seat side suction space 16k.

  Moreover, the partition door 30 is operated to open and close by an actuator controlled by an electronic control unit, for example. That is, the partition door 30 is switched between a closed state in which the partition door 30 is closed and an open state in which the partition door 30 is opened. And in the closed state, as shown in FIG. 7, the partitioning door 30 partitions between the driver's seat side suction space 16f and the passenger's seat side suction space 16k. On the other hand, in the open state, as shown in FIG. 8, the partitioning door 30 brings the driver's seat side suction space 16 f into communication with the passenger's seat side suction space 16 k. Thus, the partitioning door 30 has a configuration that can release partitioning between the driver's seat side suction space 16f and the passenger seat side suction space 16k. The partition door 30 may be a sliding door or a pivoting door, but in the present embodiment, it is a pivoting door.

  Next, the air suction mode in the air conditioning unit 10 of the present embodiment will be described. Also in the present embodiment, the air suction mode of the air conditioning unit 10 is alternatively switched to the room air suction mode, the room air suction mode, the driver side room air suction mode, and the passenger side room air intake mode.

  As shown in FIG. 7, in the inside air suction mode of the present embodiment, the partition door 30 is in a closed state. The operation of the other doors 24, 25, 26 is the same as the inside air suction mode of the first embodiment.

  Therefore, the air flow in the air conditioning case 16 in the inside air intake mode is the same as that in the first embodiment.

  As shown in FIG. 8, in the outside air suction mode of the present embodiment, the partition door 30 is in the open state. The operation of the other doors 24, 25, 26 is the same as in the open air suction mode of the first embodiment.

  Therefore, the air flow in the air conditioning case 16 in the outside air suction mode is the same as that in the first embodiment.

  As shown in FIG. 9, in the driver's seat side inside air suction mode of the present embodiment, the partition door 30 is in the open state. The operation of the other doors 24, 25, 26 is similar to that of the driver's seat side air intake mode of the first embodiment.

  Therefore, the air flow in the air conditioning case 16 in the driver's seat side inside air suction mode is the same as that in the first embodiment.

  As shown in FIG. 10, in the passenger-seat-side inside air suction mode of the present embodiment, the partition door 30 is in the open state. The operation of the other doors 24, 25 and 26 is the same as that of the passenger side internal air suction mode of the first embodiment.

  Therefore, the air flow in the air conditioning case 16 in the passenger side inward air suction mode is the same as that in the first embodiment.

  The present embodiment is the same as the first embodiment except for the above description. And in this embodiment, the effect show | played from the structure common to above-mentioned 1st Embodiment can be acquired similarly to 1st Embodiment.

  Further, according to the present embodiment, as shown in FIGS. 7 and 8, in the closed state, the partition door 30 partitions the space between the driver's seat side suction space 16 f and the passenger's seat side suction space 16 k. On the other hand, in the open state, the partition door 30 establishes communication between the driver's seat side suction space 16f and the passenger's seat side suction space 16k. That is, in the open state, the partition door 30 releases the partition between the driver's seat side suction space 16f and the passenger's seat side suction space 16k.

  Therefore, for example, in the first embodiment, the airtightness between the driver's seat side suction space 16f and the passenger's seat side suction space 16k when the partitioning door 30 divides the two suction spaces 16f and 16k from each other. It is possible to raise as compared with the partition plate 28 of this. And it is also possible to improve communication in case the partition door 30 is connecting the suction space 16f of the both and mutual between 16k compared with the partition plate 28 of 1st Embodiment, for example.

Third Embodiment
Next, a third embodiment will be described. In the present embodiment, points different from the first embodiment described above will be mainly described.

  As shown in FIG. 11, the air conditioning unit 10 of the present embodiment includes a partition wall 32 instead of the partition plate 28 of the first embodiment. In addition, the air conditioning unit 10 of the present embodiment also includes the driver's seat side internal / external air door 34. Further, the air conditioning case 16 of the present embodiment has the same outside air introducing portion 163 as the first embodiment, and further has a driver's seat side outside air introducing portion 164 separately from the outside air introducing portion 163. The present embodiment is different from the first embodiment in these points. In the present embodiment, the outside air introducing portion 163 is referred to as a passenger side outside air introducing portion 163, and the outside air introducing passage 16j is referred to as a passenger side outside air introducing passage 16j.

  Specifically, the driver's seat side outside air introducing portion 164 has a duct shape, and the driver's seat side outside air introducing passage 16 q is formed inside the driver's seat side outside air introducing portion 164. The driver's seat side outside air introduction passage 16q is also an air passage for introducing outside air, similarly to the assistant's seat side outside air introduction passage 16j.

  Therefore, the air flow upstream end of the driver's seat side outside air introduction passage 16q is connected to the driver's seat side outside air introduction port opened to the outside of the vehicle at a predetermined site on the driver's seat side in the vehicle width direction DR2, for example. On the other hand, the air flow downstream end 16r of the driver's seat side outside air introduction passage 16q is connected to the driver's seat side suction space 16f. In detail, the driver's seat side outside air introduction passage 16q is connected to the driver's seat side suction space 16f among the driver's seat side suction space 16f and the passenger's seat side suction space 16k, but the passenger's seat side suction space 16k Not connected to

  That is, the driver's seat side outside air introduction passage 16q and the driver's seat side inlet 16a are connected to the driver's seat side suction space 16f. Therefore, driver's seat side inside air flows in from driver's seat side space 901 via driver's seat side suction opening 16a into driver's seat side suction space 16f. Further, outside air flows into the driver's seat side suction space 16f from the driver's seat side outside air introduction passage 16q.

  Here, between the driver's seat side air introduction passage 16q and the driver's seat side suction port 16a and the driver's seat side suction space 16f, a driver's seat side air / door air door 34 and a driver's seat side entrance door 24 are provided. ing. Further, the driver's seat side internal / external air door 34 is provided on the air flow upstream side of the driver's seat side inlet door 24. In the present embodiment, the inside and outside air door 25 on the passenger side is referred to as the front and rear side air door 25.

  The driver's seat side inside / outside air door 34 of this embodiment is, for example, a pivoting door, and is actuated by an actuator controlled by the electronic control unit in the same manner as the front / rear passenger's side inside / outside air door 25. Then, the driver's seat side internal / external air door 34 opens and closes the driver's seat side suction port 16a and the air flow downstream end 16r of the driver's side external air introduction passage 16q. Specifically, the driver's seat side internal / external air door 34 operates so as to decrease the opening degree of the air flow downstream end 16r of the driver's seat side external air introduction passage 16q as the opening degree of the driver's seat side suction port 16a is increased. . That is, when closing the driver's seat side inlet port 16a, the driver's seat side inside / outside air door 34 maximizes the opening degree of the air flow downstream end 16r of the driver's seat side outside air introduction passage 16q. Conversely, when closing the air flow downstream end 16r of the driver's seat side outside air introduction passage 16q, the driver's seat side inside / outside air door 34 maximizes the opening degree of the driver's seat side intake port 16a together with it.

  The driver's seat side inlet door 24 is disposed downstream of the driver's seat side inlet port 16a and the air stream downstream end 16r of the driver's seat side outside air introduction passage 16q. Therefore, when the driver's seat side inlet door 24 is opened, air can flow into the driver's seat side suction space 16f from one or both of the driver's seat side inlet port 16a and the driver's seat side outside air introduction passage 16q. . Conversely, when the driver's seat side inlet door 24 is closed, communication between each of the driver's seat side suction port 16a and the driver's seat side outside air introduction passage 16q and the driver's seat side suction space 16f is shut off. That is, in that case, air can not flow into the driver's seat side suction space 16f from any of the driver's seat side suction port 16a and the driver's seat side outside air introduction passage 16q.

  Since the partition wall 32 replaces the partition plate 28 (see FIG. 2) of the first embodiment, similarly to the partition plate 28, the space between the driver's seat side suction space 16f and the passenger's seat side suction space 16k is It is provided in the air conditioning case 16 as a partition part to partition. Therefore, the partition wall 32 is provided in the air conditioning case 16 between the driver's seat side suction space 16 f and the passenger's seat side suction space 16 k. Specifically, the partition wall 32 faces the driver's seat side suction space 16f on one side in the vehicle width direction DR2, and faces the passenger's seat side suction space 16k on the other side in the vehicle width direction DR2.

  The partition wall 32 is fixed to the air conditioning case 16. For example, in the present embodiment, the partition wall 32 is integrally formed with the air conditioning case 16, and thus, is configured integrally with the air conditioning case 16. Therefore, the partition wall 32 always divides between the driver's seat side suction space 16f and the passenger's seat side suction space 16k, and blocks the flow of air between the suction spaces 16f and 16k. That is, unlike the partition plate 28 of the first embodiment, the partition wall 32 does not have a configuration that can release the partitioning between the driver's seat side suction space 16 f and the passenger's seat side suction space 16 k.

  Next, the air suction mode in the air conditioning unit 10 of the present embodiment will be described. In the present embodiment, the air suction mode of the air conditioning unit 10 is switched to the both air suction mode or the air suction mode.

  As shown in FIG. 11, in the inside air intake mode of the present embodiment, the driver's seat side entry door 24 and the passenger's seat side entry door 26 are opened. Further, the passenger side inside / outside air door 25 opens the passenger side suction port 16c and closes the air flow downstream end 16p of the passenger side outside air introduction passage 16j. Further, the driver's seat side internal / external air door 34 opens the driver's seat side inlet port 16a and blocks the air flow downstream end 16r of the driver's seat side external air introduction passage 16q.
