The upper surface of the first partition wall 911 is coupled to the lower surface of the second partition wall 913 , and the other end of the first inclined surface 912 is coupled to one end of the second inclined surface 914 to thereby bypass suction flow path 910 . is formed

The bet sucked into the first suction port 311 through the bypass suction passage 910 flows to the upper portion of the device body 100 . At this time, the bet flowing in the bypass suction flow path 910 through the first partition wall 911 and the second partition wall 913 does not meet the total heat exchanger 200 .

The bypass transmission flow path 920 is a sub flow path of the third flow path 900 disposed between the inlet side of the third flow path 900 and the outlet side of the third flow path 900 . The bypass transmission flow path 920 is formed along the fourth side surface BS4 of the second body 120 perpendicular to the first side portion BS1 of the second body 120 . The bypass transmission flow path 920 is connected to the bypass suction flow path 910 formed in the first side part BS1 of the device body 100 in a curved line. The bypass transmission flow path 920 is not formed in the first body 110 , but is formed only in the second body 120 . The bypass transfer flow path 920 is implemented in a straight line shape.

In more detail, the bypass transfer flow path 920 includes a third partition wall 921 and a horizontal surface 922 . The horizontal surface 922 is disposed between the fourth side part BS3 of the second body 110 and the third partition wall 921 and is formed horizontally. The third partition wall 921 is connected to the first partition wall 911 and the second partition wall 913 , and one end of the horizontal surface 922 is connected to the other end of the second inclined surface 914 . Accordingly, the bypass suction passage 910 and the bypass transmission passage 920 are connected.

Meanwhile, as mentioned above, the first fan 500 is disposed in the second space 1020 formed between the first body 110 and the second body 120 . Accordingly, the bypass suction flow path 910 and the bypass transmission flow path 920 are disposed above the first fan 500 , and the bypass suction flow path 910 and the bypass transmission flow path 920 are formed by the first fan ( 500) so as not to collide with it. And, according to the partition walls 911, 913, and 921 defining the bypass suction flow path 910 and the bypass transmission flow path 920, the bypass suction flow path 910 and the bypass transmission flow path 920 are installed in the installation area ( 100a).

The bypass discharge flow path 930 is a sub flow path of the third flow path 900 disposed on the outlet side of the third flow path 900 . The bypass discharge passage 930 is connected to the bypass transfer passage 920 , and the bet flowing into the bypass transfer passage 920 is guided to the first outlet 331 . At this time, the bet is efficiently discharged through the second fan (600).

In other words, the first flow path 700 and the second flow path 800 corresponding to the electrothermal ventilation mode are two-dimensional flow paths, and the third flow path 900 corresponding to the general ventilation mode is a three-dimensional flow path. At this time, the bypass suction flow path 910 is inclined with respect to the bottom surface of the first body 110 , and the bet flowing into the bypass suction flow path 910 is a bypass formed inside the second body 120 . It is connected to the transmission passage 920 . Accordingly, the third flow path 900 having a three-dimensional shape is implemented.

And, according to the partition walls 911 , 913 , and 921 , the third flow path 900 , which is a bypass flow path, does not meet the total heat exchanger 200 , and the bet flowing into the third flow path 900 goes to the total heat exchanger 200 . not transmitted In addition, the third flow path 900 is disposed above the first fan 500 . Accordingly, the third flow path 900 is formed to bypass without meeting the total heat exchanger 200 and the first fan 500 .

On the other hand, the above-mentioned damper 1050 is installed in the first space 1010 to adjust the flow direction of the bet sucked in the first suction port (311).

18 is a view for explaining an operation mode of the damper 1050 according to an embodiment of the present invention.

Referring to FIG. 18 , the damper 1050 operates in a first mode and a second mode.

At this time, referring to FIG. 18 (a), in the first mode, the door of the damper 1050 opens the first suction flow path 710 (that is, opens one surface of the first space 1010), The bypass suction flow path 910 is closed (ie, the other surface of the first space 1010 is closed). Accordingly, the bet is transmitted to the first flow path 700 , and the bet is not transmitted to the third flow path 900 . The first mode corresponds to the electrothermal ventilation mode.

And, referring to FIG. 18B , in the second mode, the door of the damper 1050 closes the first suction flow path 710 (ie, closes one surface of the first space 1010 ), and the The pass suction passage 910 is opened (that is, the other surface of the first space 1010 is opened). Accordingly, the bet is transmitted to the third flow path 900 , and the bet is not transmitted to the first flow path 700 . The second mode corresponds to the general ventilation mode.

Accordingly, the flow direction of the bet between the first flow path 700 and the third flow path 900 can be simply adjusted using one damper 1050 controlled by one motor.

On the other hand, as mentioned above, for the smooth flow of the bet to the device body 100 , the nominal cross-sectional area of the door of the damper 1050 corresponding to the nominal cross-sectional area of one surface and the other surface of the first space 1010 is the first It may be greater than or equal to the cross-sectional area of the suction port 311 .

In other words, the device body 100 is composed of the first, second, third, and fourth bodies 110 , 120 , 130 , 140 to constitute a plurality of flow paths and to fix the components of the ventilation system. In particular, the first, second, third, and fourth bodies 110 , 120 , 130 , and 140 may be made of EPS parts, and accordingly, heat insulation and sound insulation effects may be increased. And, the protrusion (B) and the groove (G) through the coupling can be prevented from leaking the bet.

In addition, the first flow path 700 as the exhaust flow path and the third flow path 900 as the bypass flow path are formed separately from each other. At this time, the third flow path 900 is implemented in a three-dimensional shape to bypass the total heat exchanger 200 and the first fan 500 . Accordingly, the third flow path 900 may be formed as the remaining space of the device body 100 , and the loss amount of the bet flowing into the third flow path 900 , that is, the loss of air volume may be reduced.

And, by installing the sensor 1040 in the first space 1010 in contact with the exhaust port, the sensor 1040 can be shared and used. That is, even when the bet flows to the first flow path 700 and when the bet flows to the third flow path 900 , the sensor 1040 may measure information. Accordingly, it is not necessary to install an additional sensor, and the manufacturing cost of the ventilation system can be reduced.

In addition, by installing one damper 1050 in the first space 1010, it is possible to simplify the control of the flow path of the bet and reduce the manufacturing cost of the ventilation system.
