However, if the outside air introduction hole 15 remains open, the water that has entered the cowl panel 4 through the outside air inlet 21 enters the air conditioner unit 12 through the outside air introduction hole 15 during rainy weather or car washing. As a result, the air conditioner unit 12 may break down.

  Therefore, conventionally, as shown in FIGS. 6 to 8, a baffle plate 22 that prevents water from entering the outside air introduction hole 15 formed in the cowl panel 4 is fixed to the cowl louver 5. Since the baffle plate 22 is a member for preventing water such as rainwater from entering the outside air introduction hole 15, it is formed larger than the opening area of the outside air introduction hole 15 as shown in FIG. It is located opposite to the outside air introduction hole 15. For this reason, when the open / close body 18 is brought to the closed position and the outside air is taken into the air conditioner unit 12 through the outside air introduction hole 15, the intake resistance is increased by the large-sized baffle plate 22, thereby deteriorating the air conditioning performance of the air conditioner unit 12. There is a fear. In addition, since the large baffle plate 22 is expensive and heavy, providing the baffle plate 22 increases the cost of the automobile and may increase the weight of the automobile.

In addition, when the blower 14 is operated in a state where the opening / closing body 18 occupies the open position shown in FIG. 2, the air from the vehicle interior IR taken into the duct 16 through the duct opening 17 is indicated by an arrow B. As shown, the air is sucked into the blower 14 and returned to the vehicle interior IR again. Thus, the basic configuration of the automobile of this example is the same as that of a conventional automobile. Therefore, the same parts as those of the conventional automobile in FIGS. 1 and 2 are denoted by the same reference numerals as those shown in FIGS. 6 to 8, and further description of the same parts as those of the conventional automobile is provided. Omitted.

  1 and FIG. 2 differs from the conventional vehicle shown in FIGS. 1 and 2 in that the vehicle is not provided with the baffle plate 22 shown in FIGS. 6 to 8 and is formed on the cowl panel 4 instead. The open / close door 23 that opens and closes the outside air introduction hole 15, and the restriction drive means that drives the open / close door 23 and the opening / closing body 18 while restricting the opening / closing body 18 as described later are provided. More specifically, the open / close door 23 has the closed position shown in FIG. 2 that closes the outside air introduction hole 15 formed in the cowl panel 4 and the open position shown in FIG. 1 that opens the outside air introduction hole 15. 2 and when the opening / closing body 18 occupies the open position shown in FIG. 2 by the restriction driving means described above, the open / close door 23 occupies the closed position shown in FIG. When the body 18 occupies the closed position shown in FIG. 1, the operations of the open / close body 18 and the open / close door 23 are restricted so that the open / close door 23 occupies the open position shown in FIG.

  The open / close door 23 includes a door front wall 24 formed in a substantially semi-cylindrical shape and each end in the vehicle width direction of the door front wall 24, as shown in FIGS. The door front wall 24 and the pair of door side walls 25 are formed into a cup-like cross-sectional shape in which the duct 16 side is opened. A lower opening 26 is formed in the lower part. An upper portion of the open / close door 23 is supported by the cowl panel 4 or the duct 16 via a pin 27 so as to be rotatable in a direction indicated by an arrow D.

  As shown in FIG. 2, when the open / close door 23 occupies the closed position, the door front wall 24 of the open / close door 23 closes the entire outside air introduction hole 15 formed in the cowl panel 4, and the outside air introduces outside air. It is prevented from flowing into the duct 16 of the air conditioner unit 12 through the hole 15. At that time, a seal member 28 made of an elastic material such as rubber or foam is fixed to the cowl panel portion around the outside air introduction hole 15, and the door front wall 24 of the open / close door 23 occupying the closed position is fixed. The outer surface is pressed against the sealing material 28, and the sealing performance in the duct 16 is improved.

  On the other hand, when the open / close door 23 occupies the open position shown in FIG. 1, the space S between the cowl louver 5 and the cowl panel 4 and the duct through the lower opening 26 formed in the lower portion of the door front wall of the open / close door 23. The space inside 16 communicates. Thus, the lower part of the door front wall 24 of the open / close door 23 is a lower part that communicates the interior space S of the cowl panel 4 and the inside of the duct 16 when the open / close door 23 occupies the open position shown in FIG. An opening 26 is formed.

  As shown in FIG. 1, in a state where the opening / closing body 18 occupies the closed position and the opening / closing door 23 occupies the open position, an occupant in the passenger compartment IR operates the blower switch to start the motor 13. When the blower 14 starts to operate, as described above, outside air outside the vehicle flows into the cowl panel 4 from the outside air inlet 21 formed in the cowl louver 5 as indicated by the arrow A. At this time, the outside air flows into the duct 16 through the lower opening 26 of the open / close door 23 occupying the open position, and is then sucked into the blower 14 and taken into the vehicle interior IR. At this time, since the opening / closing body 18 occupies the closed position, air in the passenger compartment IR does not flow into the duct 16 through the duct opening 17. Further, since the lower opening 26 of the open / close door 23 through which the outside air circulates opens downward, water such as rain water and car wash water flows between the cowl panel 4 and the cowl louver 5 from the outside air inlet 21 of the cowl louver 5. Even if it enters the space S, the water does not enter the duct 16 through the lower opening 26 of the open / close door 23. In addition to the door front wall 24, the open / close door 23 has a pair of door side walls 25 that are integrally provided at each end in the vehicle width direction. Intrusion into the duct 16 from the end portions in the direction can also be prevented. As described above, the baffle plate that is always provided in the conventional automobile is not provided, but when outside air is taken into the vehicle compartment, water such as rainwater can be prevented from entering the air conditioner unit 12.

  On the other hand, as shown in FIG. 2, when the blower 14 starts operating in a state where the opening / closing body 18 occupies the open position and the opening / closing door 23 occupies the closed position, as described above, As indicated by the arrow B, the air in the IR flows into the duct 16 through the duct opening 17 and is sucked into the blower 14 and returned to the passenger compartment IR, and the air circulates in the passenger compartment IR. At this time, since the open / close door 23 occupies the closed position, the outside air does not flow into the duct 16 through the outside air inlet 21 formed in the cowl louver 5 and the outside air introduction hole 15 formed in the cowl panel 4. Naturally, water such as rainwater that has entered the space S between the cowl panel 4 and the cowl louver 5 through the outside air inlet 21 does not enter the duct 16. Thus, in this case as well, water can be prevented from entering the air conditioner unit 12 even if the conventional baffle plate is not provided. It is possible to prevent water from entering from all directions into the outside air introduction hole 15 formed in the cowl panel 4.

  Note that when the air in the passenger compartment is circulated as described above, the open / close door 23 occupies the closed position and the outside air does not flow into the duct 16, so the open / close body 18 passes through the air flow path of the duct 16. The opening / closing body 18 may occupy the open position indicated by a two-dot chain line in FIG. 2, for example.

  As described above, according to the automobile of this example, since the baffle plate is unnecessary, it is possible to prevent deterioration of the air conditioning performance when taking outside air into the vehicle interior via the air conditioning unit. In addition, the opening / closing door 23 only needs to have a size sufficient to open and close the outside air introduction hole 15 formed in the cowl panel 4. Therefore, the size of the opening / closing door 23 is larger than that of the baffle plate used conventionally. The size can be greatly reduced. By reducing the size of the open / close door 23 as described above, it is possible to reduce the weight and cost of the automobile.

  The door front wall 24 of the open / close door 23 shown in FIGS. 1, 2 and 3A is formed in a substantially semi-cylindrical shape, but the open / close shown in FIGS. 3B and 3C is used. Like the door 23, the door front wall 24 may be formed in a quadrangular prism shape or a triangular prism shape.

  Next, when the opening / closing body 18 occupies the open position, the opening / closing door 23 occupies the closed position, and when the opening / closing body 18 occupies the closed position, the opening / closing body 18 occupies the open position. The specific configuration of the regulation drive means for regulating the operation of the opening / closing door 23 will be clarified.

  The regulation drive means shown in FIG. 4 includes a first motor 29 that operates the opening / closing body 18 between its closed position (FIG. 1) and its open position (FIG. 2), and the open / close door 23 in its closed position (FIG. 2) and a second motor 30 that operates between the open position (FIG. 1) and a control device 31. The first motor 29 rotationally drives the pivot pin 19 of the opening / closing body 18 shown in FIGS. 1 and 2 in the direction of arrow C, and the second motor 30 is used for the opening / closing door 23 shown in FIGS. 1 and 2. The pin 27 is configured to rotate in the direction of arrow D.

  A switch 32 shown in FIG. 4 is provided in the passenger compartment, and a signal generated by the occupant operating the switch 32 is taken into the control device 31, and the first and second signals are sent from the control device 31. A command is output to the motors 29 and 30, and the motors 29 and 30 are operated to drive the opening / closing body 18 and the opening / closing door 23, respectively. Thereby, the opening-closing body 18 and the opening-and-closing door 23 can occupy each position shown in FIG.1 and FIG.2. As described above, in the control device 31, the opening / closing door 23 occupies the closed position and the opening / closing body 18 occupies the closed position when the opening / closing body 18 occupies the open position by the operation of the switch 32 disposed in the vehicle interior. Then, the operation of the first and second motors 29 and 30 is controlled so that the open / close door 23 occupies the open position.

  The regulation drive means shown in FIGS. 5A and 5B includes a rotating arm 33 disposed inside the instrument panel 20 shown in FIGS. 1 and 2 and one end side of the rotating arm 33.
