The air sucked in from the suction port provided on the side of the air is separated into an air purification air passage and a humidification air passage in the main body. Sending Air that is drawn in from the first air intake of the machine, discharged from the upper outlet, blown out into the room as clean air from the air outlet on the top of the main body, and those that pass through the humidified air passage are humidified after being purified by the air purifying filter It passes through the filter, is sucked in from the second intake port of both suction type centrifugal blowers, and is blown out into the room as a humidified airflow purified from the blowout port. Since the air volume is reduced, the air volume of the air clean air path is equalized with the humid air path via the bypass air path connected to the upstream side of the humidifying filter of the humid air path from the lower discharge port of both suction blowers of the air clean air path. By supplying the air supply unit, it is possible to secure a sufficient amount of air for humidification, so that a large-capacity humidification operation can be performed, and the air cleaning function and the humidification function can be sufficiently exerted , along the upstream side of the humidification filter. Backflow A prevention plate is formed integrally with the bypass air passage, and the airflow passing through the bypass air passage is guided along the surface of the humidification filter by the backflow prevention plate, and finally joins the humidification air passage. Since the airflow passing through the bypass air passage that flows in the direction passing through the humidification filter and is discharged from the lower discharge ports provided in both suction fans is pressurized and supplied to the upstream side of the humidification filter, Although there is a possibility that the air purification filter blows out from the air purification filter so as to flow backward in the path, the above-described backflow prevention plate is provided so as to be curved from the bypass air path along the upstream side of the humidification filter. The airflow passing through the bypass air passage is guided along the surface of the humidification filter by the backflow prevention plate, and finally flows into the direction of passing through the humidification filter after joining the humidification air passage. Has an effect of preventing the reverse flow of the bypass air passage, Ru can be reliably introduced into the humidifying filter by.

  In addition, an air volume adjustment damper is installed at the lower outlet of the bypass air passage to adjust the air flow to the humidification air passage, and the total air flow and humidification amount are adjusted by the air flow adjustment damper placed in the bypass air passage. When the air flow adjustment damper is closed, the air passing through the humidification filter decreases and the humidification amount decreases, but the internal ventilation resistance decreases and the total air blown out from the air outlet is reduced. Since the air volume increases, the air cleaning function is improved. On the other hand, when the air volume adjustment damper is opened, the air volume that passes through the humidification filter increases and the humidification volume increases, but the internal ventilation resistance also increases. On the other hand, the amount of humidified air is significantly increased. Therefore, by the opening / closing operation of the air volume adjustment damper, there is an effect that it is possible to selectively use an air cleaning operation with a large air volume that does not use the humidifying function and an air cleaning operation mainly using a humidifying function that can sufficiently secure the humid air volume.

  In addition, the tip of the backflow prevention plate is extended so as to be close to the surface of the humidification filter. Since the air velocity entering the humidifying filter can be maintained and the air flow rate to the humidifying filter is secured, the humidifying amount can be stably maintained, and the backflow prevention plate is close to the humidifying filter. Therefore, the air flow passing through the bypass air passage and the air flow in the humid air passage passing through the humidification filter are not mixed until just before entering the humidification filter to prevent the generation of turbulence, and the pressurized bypass air passage The airflow passing through the airflow and the airflow in the humidified airway that is sucked in can be smoothly made to enter the humidifying filter.

It can be closed so that it overlaps with a certain lower discharge port and fits in a position that forms part of the casing of both suction fans, so it can be operated without impairing the air blowing efficiency during air cleaning operation, and the air volume adjustment Damper When the flat plate part is rotated and held in the vertical direction by a small motor around the horizontal axis, the lower discharge port can be fully opened to blow the air flow directly to the filter part. The small motor can be installed outside the bypass air passage or humidification air passage by extending the horizontal axis of the small motor that rotates the flat plate or using a joint. The pressure loss of the air passage can be reduced, and the quality of the small motor can be maintained.

  In addition, a damper storage portion for storing the flat plate portion of the air volume adjustment damper is provided on the wall surface of the bypass air passage, and when the flat plate portion is placed in a vertical state and stored in the damper storage portion, a step portion provided in the damper storage portion is provided.

There is no air passage that passes through the air inlet 9, the upper outlet 12 and the air outlet 1b in this order. There is no air path that passes through the air purifying filter 5, the humidifying filter 6, the second air inlet 10 of the both suction fans 8, the lower outlet 11, and the air outlet 1 b in this order, and the bypass air path 7 The lower discharge port 11 is connected to the upstream side of the humidification filter 6 in the humidification air passage 4.

  Further, the upper discharge port 12 and the lower discharge port 11 provided in both the suction fans 8 are arranged at substantially target positions with respect to the center of the blower fan, and the opening surface of the lower discharge port 11 facing the humidifying filter 6 is substantially omitted. It is provided horizontally.

  Further, an air volume adjusting damper 13 is provided at the lower discharge port 11 of the bypass air path 7 so that the air flow rate to the humidified air path 4 can be adjusted.

  Further, the backflow prevention plate 14 is formed integrally with the bypass air passage 7 along the upstream side of the humidification filter 6, and the airflow from the bypass air passage 7 wraps around the backflow prevention plate 14 to the humidification filter 6. It will be guided.

  Further, the tip of the backflow prevention plate 14 is extended so as to be close to the surface of the humidifying filter 6.

  The humidifying filter 6 includes a cylindrical filter portion 6a, a filter frame 6b that is rotatably supported around a horizontal axis inside the filter portion 6a, and disk portions 6c provided at both ends of the filter frame 6b. The disc portion 6c has a diameter larger than the cylindrical outer diameter of the filter portion 6a, and a leak prevention rib 6d protruding inward is formed on the periphery of the disc portion 6c.

  With the above configuration, the air sucked from the suction port 1a provided on the side surface of the main body 1 is separated into the air purification air passage 3 and the humidification air passage 4 in the main body 1, and those passing through the air purification air passage 3 After being purified by the filter 5, the air is sucked from the first air inlet 9 of both the suction centrifugal blowers 8 and discharged from the upper outlet 12, and blown into the room as clean air from the air outlet 1 b on the top surface of the main body 1. Further, the air that passes through the humidifying air passage 4 is purified by the air purifying filter 5, then passes through the humidifying filter 6, is sucked from the second air inlet 10 of the both suction centrifugal blowers 8, and is purified from the air outlet 1 b. It is blown into the room as an air current. However, since the air flow resistance of the humidification filter 6 is large in the humidification air passage 4, the amount of air flow is reduced. However, the humidification air passage 4 is humidified from the lower discharge port 11 of the both suction fans 8 of the air clean air passage 3. High-capacity humidification operation can be achieved because a part of the air volume of the air clean air path 3 is supplied to the humidified air path 4 via the bypass air path 7 connected to the upstream side of the filter 6 so as to secure the amount of air for humidification The air purifying function and the humidifying function can be sufficiently exhibited.

  Further, by providing the upper discharge port 12 and the lower discharge port 11 provided in both the suction blowers 8 at substantially the target positions, when the air is blown from the upper discharge port 12 and the lower discharge port 11, the reaction caused by the blowing can be offset.

The effective area which passes 6 can be ensured significantly and humidification efficiency can be improved.

  The air volume adjustment damper 13 disposed in the bypass air passage 7 can adjust the total air volume and the humidification amount. When the air volume adjustment damper 13 is closed, the wind passing through the humidification filter 6 is not supplied. Although the amount of humidification decreases and the amount of humidification decreases, the internal ventilation resistance decreases, and the total amount of air blown from the outlet 1b increases, so the air cleaning function is improved. On the other hand, when the air volume adjusting damper 13 is opened, the air volume passing through the humidifying filter 6 is increased and the humidified volume is increased, but the internal ventilation resistance is also increased. The humidified air volume will increase significantly relative to the air volume. Therefore, by opening and closing the air volume adjusting damper 13, it is possible to selectively use an air cleaning operation with a large air volume that does not use the humidifying function and an air cleaning operation mainly using a humidifying function that can sufficiently secure the humid air volume.

  Further, since the airflow passing through the bypass air passage 7 discharged from the lower discharge ports 11 provided in the both suction fans 8 is pressurized and supplied to the upstream side of the humidifying filter 6, the air current flows back through the humidifying air passage 4. May be blown out from the air cleaning filter 5 to the suction port 1a, but by providing the backflow prevention plate 14 integrally curved from the bypass air passage 7 along the upstream side of the humidification filter 6, The airflow passing through the bypass air passage 7 is guided by the backflow prevention plate 14 along the surface of the humidification filter 6, and finally flows in the direction of joining the humidification air passage 4 and passing through the humidification filter 6. The backflow prevention plate 14 prevents the bypass airflow 7 from backflowing and can be reliably introduced into the humidifying filter 6.

  In addition, by bringing the backflow prevention plate 14 close to the surface of the humidifying filter 6, it is possible to suppress a wasteful spread of the airflow passing through the bypass air passage 7 and maintain the wind speed entering the humidifying filter 6. The amount of humidification can be stably maintained by ensuring the amount of airflow to the airflow, and since the backflow prevention plate 14 is provided close to the humidification filter 6, the airflow passing through the bypass air passage 7 and the humidification filter 6 are passed. The air flow in the humidified air path 4 is not mixed until just before entering the humidifying filter 6 to prevent the generation of turbulent flow, and the air current passing through the pressurized bypass air path 7 and the humidified air path 4 sucked in Each airflow can smoothly enter the humidifying filter 6.
