The first casing 8e which is a casing portion is provided so as to surround the first blade 8c, and the second casing 8f is provided so as to surround the second blade 8d. The first casing 8e and the second casing 8f are both suction type casings, and are provided with circular suction ports on both side surfaces. The peripheral edge of the suction port is provided with a curved portion that is curved inward of the casing, and the upper portion is provided with a substantially rectangular discharge port.

A first inner suction port 8g of the first casing 8e which is a suction port on the inner side of each of the first casing 8e and the second casing 8f, that is, a suction port on the electric motor 8b side, and a second casing 8f. It arrange | positions so that it may become the position which faced the 2nd inner side inlet port 8i. An electric motor side space portion 9a that is a space is provided between the first inner suction port 8g and the second inner suction port 8i. The motor-side space 9a serves as an air path to the first inner suction port 8g and the second inner suction port 8i. Further, the first outer suction port 8h of the first casing 8e is an outer suction port of each of the first casing 8e and the second casing 8f, that is, a suction port on both side surfaces of the main body case 3. . The first outer suction port 8h is disposed at a position facing the first inner suction port 8g, and the second outer suction port 8j of the second casing 8f is disposed at a position facing the second inner suction port 8i. Has been. A first outer suction space portion 9 b that is a space is provided between the first outer suction port 8 h and one side surface of the main body case 3. A second outer suction space portion 9 c that is a space is provided between the second outer suction port 8 j and the other side surface of the main body case 3. The first outer suction space portion 9b serves as an air passage to the first outer suction port 8h, and the second outer suction space portion 9c serves as an air passage to the second outer suction port 8j.

That is, the blower rotating shaft 8a is provided in parallel with the humidifying filter rotating shaft 5a. Further, an electric motor side space portion 9a is provided in the central portion on the leeward side of the humidifying filter 5, and a first outer suction space portion 9b and a second outer suction space portion 9c are provided at both end portions on the leeward side of the humidifying filter 5. Provided. Therefore, air will be sucked in by the air blower 8 from three locations on the leeward side of the humidifying filter 5 and the end portions on both sides, and the air will flow more uniformly in the entire humidifying filter 5, thereby improving the humidifying ability. be able to.

Further, the horizontal distance of the air path between the first blade 8c and the second blade 8d is the air path between the outer sides of the first blade 8c and the second blade 8d and the main body case 3. Greater than the horizontal distance. Specifically, the horizontal distance of the motor-side space portion 9a is larger than the horizontal distance of the first outer suction space portion 9b and the second outer suction space portion 9c. Here, the motor-side space 9a is an air path between the first blade 8c and the second blade 8d. The first outer suction space portion 9 b and the second outer suction space portion 9 c are air paths between the outside of the first blade 8 c and the second blade 8 d and the main body case 3.

That is, air is sucked in by the air blowing unit 8 from the central portion and the both end portions of the leeward side of the humidifying filter 5. A space is provided between the both side surfaces of the humidifying filter 5 and the side surface of the main body case 3 so that the humidifying filter 5 rotates. Through this space, air flows mainly from the first outer suction space portion 9b and the second outer suction space portion 9c into the first blade 8c or the second blade 8d. Here, the horizontal distance of the motor-side space 9a is made larger than the horizontal distance of the first outer suction space 9b and the second outer suction space 9c. Thereby, the air volume which passes the center part of the humidification filter 5 is increased by increasing the air volume suck | inhaled from the motor side space part 9a. And since the humidification filter 5 rotates, the air volume which passes through space, ie, the air volume which does not pass through the humidification filter 5, can be reduced. As a result, the amount of air passing through the humidifying filter 5 can be increased.

Moreover, the cover part 5b which covers the space between the both side parts of the humidification filter 5, and the main body case 3 side part is provided. Specifically, the cover portion 5b is a substantially semicircular arc plate extending from the both side inner surface portions of the main body case 3 so as to cover the upper portions of the both side surface portions of the humidifying filter 5.

As a result, the air that does not pass through the humidifying filter 5 is formed between the space between both side surfaces of the humidifying filter 5 and the side surface of the main body case 3, the side surfaces of the humidifying filter 5, and the cover portion 5b having a substantially semicircular arc shape. Pass through the space between. Since these spaces are paths with high airway pressure loss, the amount of air that does not pass through the humidifying filter 5 can be reduced. As a result, the amount of air passing through the humidifying filter 5 can be increased.

Further, the humidifying filter rotating shaft 5a is provided almost directly below the blower rotating shaft 8a. Specifically, the air blowing unit 8 is provided almost directly above the humidifying filter 5. As a result, indoor air is sucked from the intake port 1 and air that has passed through the humidifying filter 5 is blown into the room from the exhaust port 2 by the air blowing unit 8 provided almost directly above the humidifying filter 5. The distance from the humidifying filter 5 to the blower 8 is short. Therefore, the air path resistance from the humidification filter 5 to the ventilation part 8 can be made small.

Further, the length of the humidifying filter 5 in the direction of the humidifying filter rotating shaft 5a is longer than the length from the outer side surface of the first casing 8e, which is the blower 8, to the outer side surface of the second casing 8f. Specifically, the length in the direction of the humidifying filter rotating shaft 5a is longer than the length from the first outer suction port 8h to the second outer suction port 8j.

Thus, the humidifying filter 5 is provided at a position facing the first outer suction space portion 9b and the second outer suction space portion 9c. Therefore, the flow of air from the humidification filter 5 to the first outer suction port 8h and the second outer suction port 8j is substantially straight, and the air flow can be made smooth.

The air inlet 1 is disposed on the back side of the main body case 3 and is located between the humidifying part and the air blowing part 8. Specifically, the main body case 3 has a substantially cubic shape, and a substantially horizontally long air inlet 1 is provided on the side surface on the back side. The upper end edge, which is the upper end edge of the opening of the air inlet 1, has a height at which the lower ends of the first casing 8 e and the second casing 8 f overlap with the side surface on the back side of the main body case 3. The lower end edge which is the lower end edge of the opening of the intake port 1 is substantially the same height as the height of the humidifying filter rotating shaft 5a.

Thereby, the air sucked from the air inlet 1 by the blower 8 flows from the air inlet 1 to the humidifying filter 5 slightly downward along the lower surfaces of the first casing 8e and the second casing 8f. Therefore, air also flows through the portion of the humidifying filter 5 that is lower than the humidifying filter rotating shaft 5a. As a result, the air flows almost uniformly throughout the humidifying filter 5 and the humidifying ability can be improved.

Also, the first blade 8c and the second blade 8d have the same shape and are components of the sirocco fan. The double-suction sirocco fan is provided with a disk-shaped main plate portion, and a substantially cylindrical shaft fixing portion into which the blower rotating shaft 8a is inserted at the central portion of the main plate portion. Comprises a plurality of arcuate blade portions extending from both sides of the main plate portion. Here, since the shaft fixing portion has a substantially cylindrical shape and extends long toward the electric motor 8b, the fixing allowance can be increased with respect to the air blowing portion rotating shaft 8a, so that the vibration of the blade can be reduced.

The first casing 8e and the second casing 8f are each provided with a discharge port 10 at the top, and a tongue piece 11 on the front side of the main body case 3 of the discharge port 10. Specifically, the first casing 8e is provided so as to surround the first blade 8c, and the second casing 8f is provided so as to surround the second blade 8d. The first casing 8e and the second casing 8f are both suction type casings, and are provided with circular suction ports on both side surfaces. A peripheral portion of the suction port is provided with a curved portion curved inward of the casing, and a substantially rectangular discharge port 10 is provided at an upper portion. A tongue piece portion 11 is provided on the front side of the main body case 3 of the discharge port 10. Thereby, the air sucked from the suction ports of the first casing 8e and the second casing 8f is blown from the exhaust port 2 of the main body case 3 to the front side of the main body case 3 in the direction of the tongue piece portion from the discharge port. I can do it. As a result, when driving with the back side of the main body case 3 facing away from the wall of the room, the humidified air is blown out toward the center of the room, so that the humidified air hits the wall of the room. Can be suppressed.

As described above, the present invention is expected to be used as a humidifying device for home use or office use.
