That is, according to the natural law in which air flows from the higher air pressure to the lower air, outdoor air flowing along the outer circumferential surface of the filter housing 147 moves to the lower end of the filter 13 having a relatively low air pressure.

In addition, the outdoor air that moves up and rises to the lower end of the filter 13 passes through the prefilter 131, the hepa filter 132, and the deodorization filter 133 in order. The outdoor air passing through the deodorizing filter 133 passes through the orifice 143 to reach the fan 15. In addition, by the action of the fan 15 which sucks air in the axial direction and discharges it in the radial direction, the sucked outdoor air is spread in the horizontal direction. In addition, the air spreading in the horizontal direction is moved toward the discharge grill 141 by the discharge guide portion 165 of the rear panel 16 and the air guide 144 formed on the discharge grill 14. Then, it passes through the discharge grill 141 and is finally discharged to the room.

Meanwhile, while the outdoor air is sucked through the air supply duct 31, the indoor air contaminated through the exhaust duct 32 is discharged to the outside.

In detail, a discharge fan may be provided in the exhaust duct 32 or an end of the exhaust duct 32, or a heat exchanger may be connected to allow the indoor air to be sucked toward the exhaust duct 32.

In more detail, when the pressure inside the exhaust duct 32 is lowered by the driving of the discharge fan connected to the exhaust duct 32, indoor air is introduced into the exhaust duct 32 through the exhaust grill 148. As described above, the exhaust grill 148 may be formed on a portion of the side surface and a portion of the bottom surface of the ventilation cleaning apparatus 10 so that the contaminated indoor air may be quickly discharged to the outside. In addition, the indoor air sucked through the exhaust grill 148 is blocked by the partition plate 138 and the air guide 144 formed in the discharge grill 14, and does not flow toward the inlet port 163. In addition, a portion of the fastening rib 148a inserted into the sliding groove 124 of the cover guide 12 is closed on the exhaust grill 148 based on the partition plate 138, and the inlet 162 is Open. Therefore, the phenomenon that the indoor air discharged through the exhaust grill 148 is re-introduced into the ventilation cleaner 10 does not occur.

16 is a bottom perspective view showing the flow of air in the ventilation cleaning apparatus according to the spirit of the present invention in the clean mode.

Referring to FIG. 16, when the clean mode is selected, indoor air is sucked through the indoor intake port 111. In addition, the suctioned indoor air is purified while passing through the filter 13 and then discharged back to the room through the discharge grill 141 of the discharge grill 14.

On the other hand, when the clean mode is selected, the inlet port 173 connected to the air supply duct 31 may be shielded.

In detail, since the clean mode is selected and the fan 15 is rotated, air is not sucked toward the exhaust grill 148, and thus it is not necessary to provide a separate blocking member on the exhaust port 172 side. However, since the intake port 173 communicates with the filter 13, there is a possibility that outdoor air is also sucked together when indoor air is sucked through the indoor intake port 111.

Therefore, in order to completely block the inflow of external air through the inlets 163 and 173 connected to the air supply duct 31 in the clean mode and to perform only the pure clean function, the inlets 163 and 173 are selectively selected according to a specific mode. The opening and closing device to open and close may be provided. As an embodiment, the opening and closing device may be mounted on the front or rear side of the inlet port 173 formed in the installation case 17. The opening and closing device may be automatically opened and closed according to a specific mode by the microcomputer.

Alternatively, the opening and closing device may be provided on the front or rear side of the inlet 163 of the rear panel 16. In addition, as an embodiment of the opening and closing device, a plate member which is the same as or larger than the size of the inlet openings 163 and 173 may be rotatably mounted, or the opening and closing of the inlet openings 163 and 173 may be translatable in the vertical direction. Here, the type or driving method of the opening and closing device is not limited to a specific form, it will be found that various embodiments can be proposed.

On the other hand, when the flow of the air in more detail in the clean mode to be described first, the indoor air by the drive of the fan 15 is sucked through the indoor intake port 111. The sucked indoor air is filtered while passing through the filter 13, and passes through the orifice 143 to reach the fan 15. The air reaching the fan 15 is dispersed in the horizontal direction, guided by the air guide 144 and the discharge guide part 165, and discharged back into the room through the discharge grill 141.

As can be seen from the above description, regardless of the ventilation mode or the clean mode, all the air flowing into the ventilation clean device 10 passes through the filter 13. Therefore, the air discharged to the room maintains a clean state without contamination. In addition, since the discharge grill 141 is surrounded in three directions of the side surface of the ventilation cleaning apparatus 10, the discharged air is evenly distributed throughout the room. That is, when the discharge port is formed on the bottom surface of the ventilation cleaning apparatus 10, the discharged air is dispersed only downward, thereby overcoming the disadvantage that the air cannot be delivered to the corner of the room. In addition, since the exhaust grill 148 is formed adjacent to a part of the side and a bottom of the ventilation cleaner 10, contaminated indoor air is quickly discharged. In addition, in the clean mode, an inlet for inhaling indoor air is formed on the bottom surface, and the outlet is formed on the side, thereby reducing the phenomenon that the discharged air is reintroduced through the inlet. In addition, since the suction / multiple discharge is performed in the clean mode, the indoor air is purified in a short time. In addition, the clean mode function may be simultaneously performed in the ventilation mode, and the intake panel 112 may be operably mounted so that the clean mode function may not be performed in the ventilation mode.

17 is a system diagram showing a state in which the ventilation clean device and the total heat exchanger are connected according to the spirit of the present invention.

Referring to FIG. 17, the ventilation cleaning apparatus 10 according to the present invention may be connected to the total heat exchanger 30 by a duct member, so that the total heat exchange function may be simultaneously performed together with the ventilation or clean function.

In detail, one end of the intake duct 31 and the exhaust duct 32 is connected to the ventilation cleaning device 10, the other end is connected to the total heat exchanger (30). Here, the heat exchanger (30) is a device that prevents the temperature of the room is suddenly dropped or increased by the air introduced into the room by allowing the air introduced into the room and the air discharged to the outside to mutual heat exchange. That is, when the indoor temperature is higher than the outdoor temperature, heat is transferred from the air discharged to the air to the air flowing into the room, thereby narrowing the temperature difference between the indoor temperature and the air flowing into the room, thereby rapidly changing the indoor temperature. You can stop it.

On the other hand, since the heat exchanger 30 is maintained in a stopped state while the clean mode is in operation, when the indoor air flows into the ventilation clean device 10 through the indoor intake port 111, the intake duct 31 Outdoor air is not introduced into the ventilation cleaning device 10 through). Therefore, it is not necessary to provide a separate blocking member on the outdoor air intake port side of the ventilation cleaner 10.

As described above, in the case where the intake duct 31 and the exhaust duct 32 are formed on the wall, an installation case having an intake port and an exhaust port is mounted on the side as shown. In the case where the duct members 31 and 32 pass through the ceiling, an installation case in which an inlet and an exhaust port are formed on the upper side is attached, whereby the duct members 31 and 32 can be properly installed according to the structure of the building.

By the ventilation cleaning apparatus according to the present invention constituting the configuration as described above, there is an effect that the function of air cleaning and the ventilation function is performed in one device.

In addition, by being installed out of reach of children, such as ceilings and walls, the risk of falling and failure is eliminated, and dust floating in the air is effectively filtered.

In addition, not only the air cleaning mode but also the ventilation mode, all the air discharged through the ventilation cleaning apparatus according to the present invention to pass through the filter, the clean air is always introduced into the room.

In addition, since the air cleaning function and the ventilation function are performed at the same time, the cost and installation cost of the product is reduced, and there is an additional effect of reducing the amount of power consumed to operate the product.

In addition, by improving the structure of the air flow path inside the ventilation cleaning apparatus according to the present invention, there is an effect that the flow resistance of the air flowing into the ventilation cleaning apparatus is reduced to smoothly circulate the air.
