The present invention relates to a case of an air conditioner for a vehicle, and more particularly, by extending the end of the floor discharge duct to the front thereof and engaging the shape of the bottom of the case to the front of the vehicle occupant's foot. The present invention also relates to a case of a car air conditioner for improving the comfort of the passenger by allowing the air to be discharged.

An automobile air conditioner is a device for heating or cooling an interior of a vehicle by heating or cooling air introduced from the outside to blow into an interior of a vehicle. Optionally blow into parts.

1 is a schematic diagram of a conventional case having a semi-centered type of a car air conditioner case.

When the vehicle air conditioner is set to the floor discharge mode in order to discharge cooled or heated air to the floor side of the vehicle interior, that is, when the floor outlet 101 is opened by opening the floor door 100, a blower (not shown) The blown air flows along the floor discharge duct 102 through a predetermined flow path (see arrow), and is finally discharged to the floor side of the vehicle interior through the floor discharge port 103. Typically, the floor discharge port 103 faces the rear portion of the foot of the automobile occupant.

However, as described above, in the case of the conventional air conditioner for a vehicle, the air can be discharged only to the rear of the foot without discharging the air cooled or heated directly to the entire part of the foot of the vehicle occupant. There was a certain limit to the comfort of the occupants.

The present invention has been made in order to solve the above problems, the end of the floor discharge duct is extended to the front and coupled by the shape of the bottom of the case, the floor discharge port is additionally formed to cool the entire foot of the vehicle occupant Another object of the present invention is to provide a case of an air conditioner for an automobile that increases the comfort of a passenger by allowing the heated air to be directly discharged.

In order to achieve the above object, the present invention provides a case of an air conditioner for a vehicle having an evaporator and a heater core mounted therein and having a guide wall for forming an air flow path to a floor discharge port. It is characterized in that it comprises a floor discharge duct coupled to the bottom of the case and the shape is extended, the first floor discharge port in the first half, and the second floor discharge port in the second half.

In addition, an auxiliary guide portion protruding from the bottom of the case is connected to the guide wall, and sealingly covers the floor discharge duct.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

2 and 3, the case 1 of the automotive air conditioner according to the present invention has a structure in which the floor discharge ducts 3 are coupled to each other by a shape fitting to the bottom face 2 of the case. Have. In the case, a guide wall 11 for forming an air flow path to the floor discharge ports 31 and 32 described later is provided.

On the other hand, the floor discharge duct protruding from the case bottom surface 2 and connected to the guide wall 11, and coupled to the first half portion 34 of the floor discharge duct 3 by the shape fitting with the case bottom surface 2 ( 3) an auxiliary guide part 22 covering the part) to be sealed is provided.

As shown in FIGS. 4 and 5, the floor discharge duct 3 has a first floor discharge port 31 in its first half 34 and a second floor discharge hole 32 in its second half 35. have. If necessary, it is also possible to further form a floor outlet between the first 31 and the second floor outlet 32. The first floor discharge port 31 and the second floor discharge port 32 are provided at both sides of the floor discharge duct 3 for both the driver's seat and the occupant sitting in the auxiliary seat, and the first floor discharge port is also provided. Numeral 31 is directed to the front of the foot of the vehicle occupant, and the second floor discharge port 32 is directed to the rear of the foot of the passenger.

The floor discharge duct 3 has a partition wall 33 therein for separating air flow in the direction of the first floor discharge port 31 and the second floor discharge port 32 (see FIG. 7). ).

As shown in FIG. 6, the case is provided with a guide wall 11 forming a floor discharge passage therein. The guide wall 11 seals the latter half portion 35 of the floor discharge duct 3 so as not to leak air, and one end 111 of the guide wall 11 is connected to one end 21 of the bottom surface 2 of the case. The lower part of the heater core 5 is supported. The case is preferably separated into left and right cases for assembly.

2 to 6, the operation of the case of the air conditioner for a vehicle according to the present invention having the configuration as described above is as follows.

When the air conditioner for the vehicle is set to the floor discharge mode by adjusting a cylindrical door (not shown) to discharge cooled or heated air to the floor side of the vehicle interior, the air blown by the blower (not shown) is the outer wall of the case. The floor discharge duct 3 is reached along the space between the guide wall 11 and the guide wall 11. The air flow reaching the floor discharge duct 3 is divided into two air flows by the separating wall 33 formed inside the floor discharge duct 3, respectively, and the first floor discharge port 31 and the first air discharge port 31 are respectively formed. It is discharged to the floor side of the vehicle interior through the two-floor discharge port 32. At this time, the auxiliary guide part 22 sealingly covering the front part 34 of the floor discharge duct 3 prevents air leakage. Meanwhile, in the present embodiment, the auxiliary guide part 22 is used to prevent air from leaking from the floor discharge duct 3, but the floor discharge duct 3, the guide wall 11, and the bottom of the case are provided. The structure which does not have the auxiliary guide part 22 is also possible by manufacturing the space which consists of (2) to be sealed.

On the other hand, since the first and second floor discharge ports 31 are directed toward the front and rear of the passenger's foot, respectively, the cooled or heated air is discharged to the entire passenger's foot, thereby improving the comfort of the passenger.

The present invention has been described by taking the case of the air conditioner for automobiles equipped with a cylindrical door as an embodiment, but may also be applied to a case where a flat door is mounted instead of the cylindrical door.

The present invention is shown in the drawing as a center mounting type (a structure in which all blowers / evaporators / heaters are housed in one unit), but in the case of a semi center mounting type (blower unit + evaporator / heater unit) and a three-piece (piece In the case of) type (blower unit, evaporator unit, heater unit), the same effect can be obtained by employing the same floor duct as the present invention. For example, in the case of the semi-center type, the floor duct may be coupled to one side of the case of the evaporator / heater unit and the one side of the heater unit case of the three-piece type.

According to the present invention having the configuration as described above, by allowing the cooled or heated air to be discharged directly to the entire area of the foot of the vehicle occupant, the passenger can feel the cooling or heating effect in a short time can increase the comfort of the occupant.
