The floor doors 330 and 340 allow the two-zone mode and the four-zone mode to be selectively controlled together with the console door 354, which will be described later. In this case, the two-zone mode is a mode in which two-zone control is possible, which is configured to perform independent air conditioning control to two different zones in the vehicle interior. In this case, the two zones are the left and right sides of the vehicle interior front seats.

The floor doors 330 and 340 are provided in the left flow path 316 and the right flow path 317, respectively. The floor door 330 of the left flow path 316 is rotated about the rotation shaft 331 and the floor door 340 of the right flow passage 317 is rotated about the rotation shaft 341, so that the two floor doors are independently rotation is controlled. The rotation shafts 331 and 341 of the floor doors 330 and 340 are formed in parallel with the flow direction of the air passing through the heating heat exchanger.

In addition, the floor doors 330 and 340 are disposed to directly face the rear of the heater core 320 . The rear of the heater core 320 is a downstream side of the heater core 320 in the air flow direction. That is, the direction of air passing through the heater core 320 is the y-axis direction, and the rotation shafts 331 and 341 of the floor doors 330 and 340 are formed in the y-axis direction. Accordingly, it is possible to selectively control the 2-zone mode and the 4-zone mode while the floor doors 330 and 340 occupy a small space in the slim heating case 310 .

In the heating case 310 , a support wall 356 is formed downstream of the heater core 320 in the air flow direction. The support wall 356 extends from a partition wall 355 partitioning the first flow passage 301 and the second flow passage 302 and a partition wall 315 partitioning the left flow passage 316 and the right flow passage 317 . .

The support wall 356 is formed symmetrically to the left channel 316 and the right channel 317 . By rotation of the floor doors 330 and 340, the dome portion of the floor doors 330 and 340 is rotated in the circumferential direction to adjust the opening degree of the floor vent 313, or to move the floor vent 313 to the first flow path. (301) or the second flow path (302) through or blocked.

That is, when the floor doors 330 and 340 are in close contact with the upper portion of the support wall 356 in the z-axis direction, the first flow path 301 and the floor vent 313 are partitioned, and the second flow path 302 and the floor The vent 313 is through. In addition, when the floor doors 330 and 340 are in close contact with the lower portion of the support wall 356 in the z-axis direction, the first flow path 301 and the floor vent 313 communicate with each other, and the second flow path 302 and the floor The vent 313 is partitioned. By adjusting the rotation angle of the floor doors 330 and 340 , the degree of opening of the floor vent 313 and the degree of communication with the first flow passage 301 and the second flow passage 302 can be adjusted.

The console door 354 controls the opening degree of the console vent 314 . The console door 354 is made of a dome-shaped rotary door. The axis of rotation of the console door 354 is formed in the x-axis direction. By rotating the console door 354, the dome portion of the console door 354 is rotated in the circumferential direction to adjust the opening degree of the console vent 314, or to allow the second flow path 302 to pass through the first flow path 301, or clog it up In this way, the console door 354 selectively controls the two-zone mode and the four-zone mode together with the floor doors 330 and 340 .

That is, in the two-zone mode and the two-layer flow mode, the floor doors 330 and 340 open the floor vent 313 and block the floor vent 313 with the first flow path 301 and the second flow path ( 302). In addition, in the 4-zone mode, the console door 354 opens the console vent 314 and divides the first flow path 301 and the second flow path 302 . The floor doors 330 and 340 adjust the opening degree of the floor vent 313 according to various air conditioning modes. Operation of specific doors for each mode will be described in detail later.

In addition, the direction of air passing through the evaporator 120 and the heater core 320 is formed in the y-axis direction. More specifically, the moving direction of the air flowing into the cooling unit 100 is formed in the y-axis direction. After the air introduced in the y-axis direction passes through the evaporator 120 in the y-axis direction, it is bent by 90° along the flow path of the cooling case 110 to move in the x-axis direction.

The air that has passed through the evaporator 120 and moved in the x-axis direction is introduced into the blowing unit 200, and the air introduced into the blowing unit 200 is moved in the z-axis direction through both sides of the first blower wheel 210 and It is sucked through both sides of the second blower wheel 220 and is helically blown in the radial direction and moves in the x-axis direction. Thereafter, the air moves in the x-axis direction through the heating case 310 coupled to the blower case 240 and is then bent 90° in the heating unit 300 to move in the y-axis direction. Thereafter, the air passes through the heater core 320 in the y-axis direction and is then selectively discharged through a plurality of air outlets.
