  The problem in the above conventional example is that the amount of humidified air clean air flow is small.

  That is, in the conventional product, the indoor air sucked from the intake port by the blowing unit is blown into the room from the exhaust port through the air cleaning unit and the humidifying unit. In this way, humidified and purified air that has been subjected to humidification and air purification treatment is supplied. However, since the humidification means is composed of a cylindrical humidification filter, the air blown from the humidification means is first outside the humidification filter. To the inside of the cylindrical humidifying filter, and then from the inside of the cylindrical humidifying filter to the outside of the humidifying filter. That is, since it passes through the humidification filter twice, the ventilation resistance in the humidification means increases.

  In addition, since the intake port, the blower unit, and the exhaust port are located at the upper part of the humidifying unit, the direction of the air blown from the upper part of the humidifying unit is changed inside the cylindrical humidifying filter, and the upper part from the inside of the cylindrical humidifying filter It is blown to the exhaust port. That is, the air flow is changed by about 180 degrees by the humidifying means, and the ventilation resistance is increased.

  Thus, since the ventilation resistance is large, the air volume of the humidified air clean air becomes small.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to reduce the ventilation resistance and increase the volume of humidified air clean air.

In order to achieve this object, the present invention comprises a main body case having an intake port and an exhaust port, an air purifying means and a humidifying means provided in the main body case, and the humidifying means is a disc-shaped humidifying filter.

  Hereinafter, the present embodiment will be described with reference to the accompanying drawings.

(Embodiment 1)
As shown in FIGS. 1, 2, 3, and 4, the air purifier with a humidifying function of the present embodiment includes a vertically long box-shaped main body case 3 having an intake port 1 and an exhaust port 2, and the main body case 3. An air purifying means and a humidifying means provided inside are provided. An intake port 1 is provided on the side surface of the main body case 3, and an exhaust port 2 is provided on the top surface of the main body case 3.

  The air purifying means is an air purifying filter 5 in which a filter medium folded in a bellows shape is fixed to a frame-like frame, and is provided in the vicinity of the air inlet 1. Air sucked from the air inlet 1 of the main body case 3 first flows into the air cleaning filter 5.

  The humidifying means is formed of a moisture release portion, a water supply portion, and a rotating means for rotating the moisture release portion.

  The moisture releasing portion is formed by a disc-shaped humidifying filter 6 and a humidifying filter frame 7 fixed to the humidifying filter 6 and rotatably provided. The humidifying filter frame 7 includes a water supply unit 9 on the outer periphery.

  The humidifying filter 6 has a property of holding water, and when air passes through the humidifying filter 6 while holding the water, the water is vaporized, and high-humidity air is discharged from the exhaust port 2 into the room. Is.

  The humidifying filter frame 7 sandwiches and fixes the humidifying filter 6. The humidifying filter frame 7 includes a water supply portion and a moisture release portion.

  The water supply portion is provided with a substantially bowl-shaped water tank 8 below the humidifying filter 6 and a water tank 4 for supplying constant water to the water tank 8. The humidifying filter frame 7, which is a moisture releasing portion, includes a water supply unit 9 on the outer periphery, and the humidifying filter frame 7 is installed so that a part of the water supply unit 9 and the humidifying filter 6 are always immersed in the water supplied to the water tank 8. An electric motor 10 that is a rotating means for rotating the water supply unit 9 and the humidifying filter 6 is provided.

  The air sucked into the main body case 3 from the air inlet 1 by the air blowing means 11 is blown to the air outlet 2 through the air purifying filter 5 which is an air purifying means and the humidifying filter 6 which is a moisture releasing portion in order. This blower means 11 is provided on the downstream side of the humidifying filter 6.

  The air cleaning and humidification operation in such a configuration will be described. Water is supplied from the water tank 4 to the water tank at a constant level. The water supply part 9 which is a moisture release part and a part of humidification filter 6 are always immersed in this water. Here, the water supply unit 9 and the humidification filter 6 are rotated by the electric motor 10 which is a rotating means, and the water pumped up by the water supply unit 9 is dripped near the top to wet the humidification filter 6.

  A feature of the present embodiment is that a bypass air passage 12 that connects the air purifying means and the air blowing means 11 is provided, and that the humidifying filter 6 and the bypass air passage 12 are provided at a position facing the suction port 13 of the air blowing means 11. is there. That is, the bypass air passage 12 connects the air purifying means and the air blowing means 11 without passing through the humidifying filter 6 as the humidifying means, and the air sucked into the main body case 3 from the intake port 1 is the air purifying means. Air is sent from the air cleaning filter 5 to the blowing means 11 via the bypass air path 12 separately from the air cleaning humidification air path that is blown to the blowing means 11 through the humidifying filter 6 that is the humidifying means. It is equipped with an air clean air path.

  As described above, the air blowing means 11 is provided on the downstream side of the disc-shaped humidifying filter 6 serving as the humidifying means, the bypass air passage 12 connecting the air cleaning filter 5 and the air blowing means 11 is provided, and the humidifying filter 6 and the bypass air passage are provided. 12 is provided at a position opposite to the suction port 13 of the air blowing means 11, so that the air sucked from the air inlet 1 passes through the humidifying filter 6 through the air cleaning filter 5, and bypasses the air sucked into the air blowing means 11. Two paths of air, which passes through the air passage 12 and is sucked in by the blowing means 11, are exhausted from the exhaust port 2 into the room by the blowing means 11.

  As a result, the number of times of passage through the humidifying filter 6 is one, and the air flow is blown without changing direction in the humidifying filter 6 which is a humidifying means. That is, the air flow in the humidifying filter 6 in the air purifying humidifying air passage that is sucked from the air inlet 1 and passes through the humidifying filter 6 through the air purifying filter 5 and sucked into the blowing means 11 is in a straight line, and the airflow resistance by the air passage is reduced. Can be small. Furthermore, since the bypass air passage 12 that does not include the humidifying means is provided, the air purification air passage has no ventilation resistance of the humidifying filter 6 that is the humidifying means, and instead becomes the ventilation resistance of the bypass air passage 12, so the ventilation resistance is Get smaller. Based on these results, the air volume of the humidified air clean air can be increased.

  Moreover, the air purifying filter 5 which is an air purifying means is provided in the position facing the suction inlet 13 of the ventilation means 11, has an area larger than the humidifying filter 6, protrudes from the upper end of the water supply part 9 of the humidifying means, and from the air purifying means. The cross-sectional area of the air path to the humidifying filter 6 gradually decreases from the area of the air cleaning means to the area of the humidifying filter. That is, since the area of the air purification filter 5 is larger than the area of the humidification filter 6 and the larger portion protrudes from the upper end of the water supply unit 9 of the humidification means, the air path from the air purification filter 5 to the humidification filter 6 is air. The air path gradually narrows from the clean filter 5 area to the humidifying filter 6 area, and the narrowed portion is an air purifying filter portion protruding from the upper end of the water supply unit 9 of the humidifying means.

  Thus, since the area of the air purification filter 5 is larger than the area of the humidification filter 6, the ventilation resistance of the air purification filter 5 is small, and the air path from the air purification filter 5 to the humidification filter 6 is an air purification filter. Since the air passage gradually narrows from the 5 area to the humidifying filter 6 area, there is no sudden change in the air passage cross-sectional area in the air passage, so the ventilation resistance is reduced and the air volume can be increased. .

  Further, the bypass air passage 12 is provided in the upper part of the water supply unit 9 of the humidifying means. That is, in the bypass air passage 12, the air that has passed through the air purification filter 5 that is larger than the area of the humidification filter 6 and protrudes from the upper end of the water supply unit 9 of the humidification means from the air purification filter 5 to the humidification filter 6. Since the air path to the air flows along the upper part of the air path gradually narrowing from the area of the air purifying filter 5 to the area of the humidifying filter 6, the ventilation resistance is reduced and the air volume of the humidified air can be increased. Is.

  Moreover, the center of the suction inlet 13 of the ventilation means 11 is located above the rotating shaft of a humidification means. That is, the flow of air in the air purification air passage that is sucked from the air inlet 1 and passes through the bypass air passage 12 through the air purification filter 5 and is sucked into the air blowing means 11 is also substantially straight, thereby reducing the ventilation resistance by the air passage. Therefore, the air volume of the humidified air can be increased.

  Moreover, the center of the suction inlet 13 of the ventilation means 11 is located in the downstream of the rotation direction in which the water supply part 9 rotates from near uppermost point. Here, when the humidification filter 6 is divided into a downstream side and an upstream side in the rotation direction in which the water supply unit 9 rotates from the vicinity of the highest point on a vertical plane connecting the uppermost point supplied by the water supply unit 9 and the center of the rotation axis, The portion 9 supplies water to the humidifying filter 6 near the uppermost point, and water is contained in the humidifying filter 6 by this water supply. Therefore, the humidifying filter 6 on the downstream side surface in the rotational direction in which the water supply portion 9 rotates from the uppermost point is upstream. Compared with the humidifying filter 6 on the side surface, more water is contained, and the center of the suction port 13 of the air blowing means 11 is located on the downstream side in the rotational direction in which the water supply unit 9 rotates from the vicinity of the uppermost point. More air flows to the humidifying filter 6 on the downstream side than the humidifying filter 6 of the above, that is, a large amount of air flows to the humidifying filter 6 portion containing a lot of water, so There is improved.

  Further, the blowing surface on the suction port 13 side of the blowing means 11 has the inclined surface 14 on the air cleaning means side so as to spread from the blowout port 15 of the blowing means 11 to the exhaust port 2, that is, the blowing of the blowing means 11. Since the blowing surface on the suction port 13 side of the air blowing means 11 is provided with an inclined surface 14 inclined toward the air cleaning means so as to gradually spread from the outlet 15 to the exhaust port 2, the air blowing from the air outlet 15 of the air blowing means 11 Since the exhausted air is exhausted from the exhaust port 2 into the room through the air passage that gradually spreads to the exhaust port 2, the ventilation resistance in the air passage is reduced and the exhaust port 2 can be further increased. Ventilation resistance is reduced, and the air volume of the humidified air can be increased.

  Further, the inclined surface 14 of the blowing surface of the blowing means 11 has a curved shape, that is, the air blown from the blowing surface 15 of the blowing means 11 through the outlet 15 of the blowing means 11 to the exhaust port 2. Since it is a curved shape that is convexly curved in the gradually expanding air passage, air is blown out along the inclined surface of this curved shape, that is, the air is blown out toward the front surface of the main body case 3, so that the blowing range is wide. Become.

  In addition, since the wind direction plate 16 provided rotatably at the exhaust port 2 is provided, the wind direction can be easily adjusted.

  Further, since the wind direction plate 16 has the center of rotation on the blowing surface side of the blowing means 11 on the fixed side of the electric motor 10, it can be easily blown toward the front surface of the main body case 3. When placed nearby, it can be blown out toward the center of the room.

  As described above, the present invention includes a main body case having an intake port and an exhaust port, and an air purifier and a humidifier provided in the main body case. The humidifier includes a disc-shaped humidifier filter and the humidifier. A humidifying filter frame that is fixed and rotatable with a filter, a substantially bowl-shaped water tank provided at a lower portion of the humidifying filter, a water tank 4 that supplies a certain amount of water to the water tank, and the humidifying filter frame. The humidifying filter frame is provided with a water supply unit 9 on an outer peripheral portion thereof, and the humidifying filter is provided so that the water supply unit 9 and a part of the humidifying filter are always immersed in the water supplied to the water tank. In addition to providing a frame, there is provided air blowing means for blowing air sucked into the main body case from the air intake opening to the air exhaust opening through the air cleaning means and the humidifying filter in this order. A blower means is provided on the downstream side of the humidifying filter, a bypass air passage connecting the air cleaning means and the blower means is provided, and the humidifying filter and the bypass air passage are located at positions facing the suction port of the blower means. It is provided and can reduce the ventilation resistance and increase the air volume of the humidified air.

  That is, the humidifying means is a disc-shaped humidifying filter, and is provided with a blowing means on the downstream side of the humidifying filter, providing a bypass air passage connecting the air cleaning means and the blowing means, and connecting the humidifying filter and the bypass air passage to the air blowing means. Since it is provided at a position opposite to the suction port, the air sucked from the suction port passes through the air purifying means, passes through the humidification filter and is sucked into the blowing means, and passes through the bypass air passage and sucked by the blowing means. The two air paths are exhausted from the exhaust port into the room by the blowing means. As a result, the number of passes through the humidification filter is halved to 1 and the air flow is not changed in direction by the humidification means. Furthermore, since a bypass air passage not through the humidifying means is provided, the ventilation resistance is reduced.

  Based on these results, the air volume of the humidified air clean air can be increased.

  Therefore, it is expected to be utilized as an air purifier with a humidifying function for home use or office use.
