Description

TECHNICAL FIELD [0001] The present invention relates to an air conditioner for an automobile,

The present invention relates to a vehicle air conditioner, and more particularly, to an air conditioner for a vehicle, which comprises a shower duct coupled to an air conditioning case and a cooling duct integrally formed to improve assembling performance between the shower duct and a cooling duct, The present invention relates to an air conditioner for a vehicle.

Generally, the air conditioner for a vehicle is an automobile interior which is installed for the purpose of securing the front and rear view of the driver by removing the casting which is to be cooled or heated in the summer or winter season, or in case of rain or windshield during rainy or winter season Such an air conditioner is usually equipped with a heating device and a cooling device at the same time, and selectively introduces outside air or indoor air, and then the air is heated or cooled to blow air into the inside of the vehicle.

2 is a perspective view showing an outer shape of a conventional automotive air conditioner. In the air conditioner 1, an air inlet 11 is formed on one side of the air conditioner 1 An air conditioning case 10 provided with a defrost vent 12a, a face vent 12b, and floor vents 12c and 12d whose opening is adjusted by the mode doors 16a, 16b and 16c, respectively, (Not shown) connected to the air inlet 11 of the case 10 to blow indoor air or outdoor air, an evaporator 2 and a heater core 3 built in the air conditioning case 10, (P1) installed between the heater core (2) and the heater core (3) and bypassing the heater core (3) and the opening of the hot air passage (P2) passing through the heater core And a temperature control door (15).

Further, the floor vents 12c and 12d are branched into a floor vent 12c for the front seat and a floor vent 12d for the rear seat.

Since the temperature difference between the front seat and the rear seat is large, the air ventilation air is guided to the rear side of the floor vents 12c and 12d toward the console box (not shown) And a console vent 12e to be supplied is installed.

According to the vehicle air conditioner 1 configured as described above, when the maximum cooling mode is activated, the temperature control door 15 opens the cold air passage P1 and closes the warm air passage P2 do. Accordingly, the air blown by the blower (not shown) flows through the evaporator 2, exchanges heat with the refrigerant flowing in the evaporator 2 and is converted into a cool air, and then passes through the cool air passage P1 to the mixing chamber MIXING CHAMBER, MC), and thereafter flows into a vent which is opened by the mode doors 16a, 16b, 16c in accordance with a predetermined air discharge mode (vent mode, bi-level mode, floor mode, So that cooling in the vehicle interior is performed.

When the maximum heating mode is activated, the temperature control door 15 closes the cold air passage P1 and opens the warm air passage P2. Thus, the air blown by the air blowing device (not shown) flows through the heater core 3 through the hot air passage P2 after passing through the evaporator 2 and the cooling water flowing in the heater core 3, The air is discharged to the inside of the vehicle through the vent opened by the mode doors 16a, 16b and 16c in accordance with the predetermined air discharge mode, .

When the mixing mode is activated, the temperature control door 15 rotates to the neutral position to open both the cold air passage P1 and the hot air passage P2 with respect to the mixing chamber MC. Accordingly, the cool air passing through the evaporator 2 and the warm air passing through the heater core 3 flow into the mixing chamber MC and are mixed and then mixed by the mode doors 16a, 16b, and 16c And the air is discharged to the inside of the vehicle through the vent to adjust the interior temperature of the vehicle to an appropriate temperature.

The floor vent 12c is formed on both sides of the air conditioner case 10 and the floor vent 12c is provided with a shower duct 12c for discharging air to the feet of the driver and passengers 20 are respectively installed.

One end of the shower duct 20 is coupled to the floor vent 12c and the other end is extended to a driver's seat and a passenger seat side by a predetermined length and a discharge port 20a is formed at a lower side thereof.

Therefore, the air that has passed through the floor vent 12c is discharged through the shower duct 20 toward the feet of the driver and passengers.

In recent years, a cooling box 30 is installed in a certain space in a glove box (not shown) in front of the passenger's seat of a vehicle. This allows the cooling of the contents stored in the cooling box 30, .

At this time, if a separate air conditioning system is installed to supply the air conditioning air to the cooling box 30 side, the cost increases. Therefore, generally, a part of the air discharged from the downstream side of the evaporator 2 in the front air conditioning system 1 And branches toward the cooling box 30 side to have an air conditioning effect.

A cooling duct 32 extending from one side of the air conditioning case 10 to the cooling box 30 for supplying air to the cooling box 30 is provided.

The cooling duct 32 of the conventional air conditioner 1 is formed at a position adjacent to the shower duct 20 on one side in the direction in which the air blowing unit 40 is installed in the air conditioning case 10, The assembly of the air conditioner 1 is complicated because the air blowing unit 40, the shower duct 20, the cooling duct 32 and the peripheral parts interfere with each other during assembly of the air conditioner 1, But also to the decision of.

In addition, the space for coupling the shower duct 20 and the cooling duct 32 is narrow and the fastening method can not be simplified, thereby causing frequent misassembly and detaching.

In addition, since the cooling duct (32) of the conventional air conditioner (1) is made of a rubber material and is vulnerable to a high temperature environment and a flammable material, and the cooling duct (32) There is a problem that the assembling of the blower unit 20 and the blower unit 40 and the peripheral parts becomes very complicated.
