Description

  The present invention relates to an air conditioning system for a vehicle that performs air conditioning with priority given to a front seat 101.

  Conventionally, various proposals have been made on a vehicle air-conditioning system that performs zone air conditioning (so-called internal air circulation) that preferentially air-conditions a passenger seated only in the front seat. An example of such a vehicle air conditioning system will be described with reference to FIG. 15 (see, for example, Patent Document 1).

  As shown in FIG. 15, the vehicle air conditioning system 100 converts air sucked into a blower passage by a blower into a desired conditioned air by a heat exchanging unit, and converts the conditioned air into an air conditioning outlet (a def outlet). An air conditioner (not shown) from the vent outlet and the foot outlet, and an air mat type partition panel 110 that partitions the front seat 101 and the rear seat 102 by injecting and extending air in the passenger compartment. I have.

  In this vehicle air conditioning system, when an occupant is seated only in the front seat 101, the partition panel 110 partitions the space on the front seat 101 side and the space on the rear seat 102 side from the air conditioning outlet. Air-conditioned air blows into the space on the front seat 101 side. It is possible to prevent the blown air-conditioning air from striking the partition panel 110 and flowing into the rear seat space, thereby realizing zone air conditioning in which the front seat 101 is preferentially air-conditioned.

To control. Specific switching contents will be described later.

(Operation of air conditioning system for vehicles)
Next, the operation of the above-described vehicle air conditioning system 10 will be described with reference to FIGS.

  Here, as described above, the vehicle air conditioning system 10 includes the overall air conditioning mode (so-called normal air conditioning mode) and the zone air conditioning mode. In addition, about each mode, although it has the function at the time of air_conditioning | cooling in the compartment 2, the heating time heated from a passenger | crew's step is demonstrated.

(Overall air conditioning mode)
In the overall air conditioning mode, as shown in FIG. 4, when the air conditioner 20 is driven, air is sucked into the air passage 22 by the blower 26 from the outside air introduction port 23 and the inside air introduction port 24. The sucked air is converted into conditioned air at a desired temperature by the evaporator 27 and the heater core 28, and the conditioned air is blown into the vehicle compartment 2 from the foot outlets 33a and 33b and the rear outlet 41B. As shown in FIGS. 4 and 5, the foot air outlets 33a and 33b are opened and the rear air outlet 41B is also opened, and the conditioned air is blown out from the opened air outlet. In the overall air conditioning mode, the blowout duct door 37 and the open / close door 60 adjust the amount of conditioned air blown from the rear outlet 41B according to the stop position.

  Then, the conditioned air is blown out into the passenger compartment 2 (rear of the vehicle 1) from the rear outlet 41B. At this time, the expansion / contraction part 84 of the expansion / contraction partition means 80 is in a contracted state without increasing the internal pressure of the conditioned air in the blowing duct 40. Therefore, the conditioned air blown out from the air conditioner 20 into the passenger compartment 2 flows to almost the entire area of the passenger compartment 2, and the entire interior of the passenger compartment 2 is air-conditioned.

(Zone air conditioning mode)
In the zone air conditioning mode, the conditioned air at a desired temperature is blown into the passenger compartment 2 from the foot outlets 33a and 33b, as in the overall air conditioning mode. As shown in FIG. 6, the foot outlets 33a and 33b are opened, and the rear outlet 41B is closed with the open / close door 60 as a closed position. At this time, since the blowout duct door 37 is in the open position, the conditioned air directed toward the rear outlet 41B loses its destination, the internal pressure of the conditioned air in the blowout duct 40 increases, and the conditioned air expands and contracts the telescopic partition means 80. The air is blown into the portion 84. Thereby, the expansion / contraction part 84 of the expansion / contraction partition means 80 is in an extended state, and the lower space of the front seat 4 is partitioned into the front seat 4 side and the rear seat 5 side of the vehicle 1.

  Then, the conditioned air blown into the passenger compartment 2 intensively passes through the vicinity of the front seat 4 (mainly the height position of the lower body of the occupant), and the foot suction port 38 ( 2), the air is sucked by the suction force of the blower 26 and returned to the air conditioning unit 21. As a result, the conditioned air can be prevented from flowing into the space of the rear seat 5, and a zone air-conditioning region is formed in the front seat 4 in the passenger compartment 2.

  Here, when neither the general air-conditioning mode nor the zone air-conditioning mode is used, the rear outlet 41B functions as a discharge port for discharging the conditioned air inside the telescopic partitioning means 80 (the telescopic part 84) to the outside.

(Action / Effect)
In the first embodiment described above, the expansion / contraction partition means 80 extends and contracts in the vertical direction by the conditioned air to partition the front seat 4 and the rear seat 5 in the space below the front seat 4. Therefore, it is possible to prevent the conditioned air from flowing to the rear seat side without requiring a dedicated drive source for blowing air.

  In the first embodiment, the rear air outlet 41B functions as a discharge port for discharging the conditioned air inside the expansion / contraction partition means 80 (expansion / contraction part 84) to the outside, so that it is necessary to provide a separate discharge port for the expansion / contraction partition means 80. Absent. Specifically, for example, when the expansion / contraction partition means 80 is formed with a discharge port, when the expansion / contraction partition means 80 (the expansion / contraction part 84) is extended, the discharge port needs to be closed or discharged from the discharge port. It is necessary to send more conditioned air than the conditioned air to the telescopic portion 84. For this reason, even if it does not provide a separate discharge port in the expansion / contraction partition means 80, the rear air outlet 41B functions as a discharge port, whereby the conditioned air inside the expansion / contraction partition means 80 (expandable portion 84) can be discharged to the outside.

  In 1st Embodiment, the rear duct mounted in the vehicle 1 can be utilized effectively by utilizing the rear duct in which the blowing duct 40 supplies conditioned air to the foot side of the rear seat 5. Moreover, since it is not necessary to provide the exclusive blowing duct 40 from the ventilation path 22 to the expansion-contraction partition means 80 other than a rear duct, it contributes also to reduction of installation space.

  Here, in 1st Embodiment, although the blowing duct 40 demonstrated as having the back blower outlet 41B which blows off an air conditioned wind to the backseat 5 side under the front seat 4, it is not limited to this, For example, instead of the rear outlet 41B, the conditioned air may be blown out to the front seat 4 side below the front seat 4.

Thereby, the expansion / contraction part 84 of the expansion / contraction partition means 80 is in an extended state, and the lower space of the front seat 4 is partitioned into the front seat 4 side and the rear seat 5 side.

  Further, the front air outlet 41A is opened toward the front side of the vehicle 1, so that the conditioned air is blown out from the front air outlet 41A to the front of the vehicle 1. Therefore, the conditioned air blown into the passenger compartment 2 intensively passes around the front seat 4 (mainly the height position of the lower body of the occupant) and from the foot suction port 38 connected to the inside air introduction port 24. The air is sucked by the suction force of the blower 26 and returned to the air conditioning unit 21. As a result, the conditioned air can be prevented from flowing into the space of the rear seat 5, and a zone air-conditioning region is formed in the front seat 4 in the passenger compartment 2.

  Here, when neither the general air-conditioning mode nor the zone air-conditioning mode is used, the front air outlet 41A and the rear air outlet 41B function as outlets for discharging the conditioned air inside the expansion / contraction partition means 80 (expansion / contraction part 84) to the outside.

By being adjusted, conditioned air can be blown to the rear duct 44 in either or both of the front duct 43 and the rear duct 44. In particular, the front air outlet 41 </ b> A and the rear air outlet 41 </ b> B can adjust the direction and volume of the conditioned air according to the stop positions of the front opening / closing door 62 and the rear opening / closing door 63, respectively.

[Other Embodiments]
Although the contents of the present invention have been disclosed through the embodiments of the present invention as described above, it should not be understood that the descriptions and drawings constituting a part of this disclosure limit the present invention. From this disclosure, various alternative embodiments, examples, and operational techniques will be apparent to those skilled in the art.

  For example, the embodiment of the present invention can be modified as follows. Specifically, the vehicle air conditioning system 10 is not limited to that described in each embodiment, and the items described in each embodiment are merely examples, and various configurations described in each embodiment. May be combined.

  Further, the vehicle air conditioning system 10 has been described by taking the case of heating in the passenger compartment 2 as an example. However, the present invention is not limited to this, and is not limited to this. Of course, the present invention can also be applied to the bi-level method.

  Moreover, although the blowing duct 40 was demonstrated as using the rear duct which supplies an conditioned air to the foot side of the rear seat 5, it is not limited to this, A duct exclusive for other than a rear duct may be sufficient.

  In addition, the blowout duct 40 and the expansion / contraction partitioning unit 80 have been described as being provided on the driver's seat side and the passenger seat side. However, the present invention is not limited to this, and at least one of them (for example, only the driver's seat side). May be provided. It may be controlled to drive only one of the driver seat side and the passenger seat side.

  Further, the blowout duct 40 and the expansion / contraction partition means 80 are not necessarily provided in the driver seat or the passenger seat, and may be provided, for example, between the driver seat and the passenger seat. The telescopic partitioning means 80 does not necessarily divide the space below the front seat 4 into the front seat 4 side and the rear seat 5 side, and the front space and the rear of the vehicle 1 between the front seat 4 and the rear seat 5. The space may be partitioned.

  In addition, the open / close door 60 has been described as being configured by a pivot door, but is not limited thereto, and may be configured by, for example, a slide door.

  Furthermore, although the extension partitioning means 80 (the lower side plate part 81, the upper side plate part 83, and the extension part 84) has been described as having a width wider than the width of the seat cushion 4a, the invention is not limited to this. What is necessary is just to be able to partition the lower space of the cushion 4a into the front side and the rear side of the vehicle 1, for example, it may be substantially equal to the width of the seat cushion 4a.

  As described above, the present invention naturally includes various embodiments that are not described herein. Therefore, the technical scope of the present invention is determined only by the invention specifying matters according to the scope of claims reasonable from the above description.
