The first blade 8c is fixed to one rotating shaft, and the second blade 8d is fixed to the other rotating shaft. The first blade 8c and the second blade 8d are both-suction type sirocco fans, and are substantially cylindrical in which a disk-shaped main plate portion and a rotating shaft 8a of an electric motor are inserted in the central portion of the main plate portion. A shaft fixing portion having a shape is provided, and a plurality of arc-shaped blade portions extending from both surfaces of the main plate portion are provided on the outer peripheral portion of the main plate portion.

  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, and a curved portion in which the periphery of the suction port curves inwardly of the casing. The upper part is provided with a substantially rectangular discharge port.

  A first inner suction port 8g of the first casing which is an inner suction port of each of the first casing 8e and the second casing 8f, that is, a suction port on the electric motor side, and a second inner side of the second casing. It is comprised in the position where the suction inlet 8i opposes. Between the first inner suction port 8g of the first casing and the second inner suction port 8i of the second casing, there is a motor-side space portion 9a that is a space. This is an air path to the first inner suction port 8g of one casing and the second inner suction port 8i of the second casing. Further, the first outer suction port 8h of the first casing, which is the outer suction port of each of the first casing 8e and the second casing 8f, that is, the suction port on the both side surfaces of the main body case 3, is The second outer suction port 8j of the second casing is configured at a position facing the second inner suction port 8i of the second casing at a position facing the first inner suction port 8g of the first casing. ing. A first outer suction space portion 9b that is a space is provided between the first outer suction port 8h of the first casing and one side surface of the main body case 3, and a second outer suction port of the second casing. And the other side surface of the main body case 3 are provided with a second outer suction space portion 9c which is a space. The first outer suction space portion 9b serves as an air passage to the first outer suction port 8h of the first casing, and the second outer suction space portion 9c extends to the second outer suction port 8j of the second casing. It has become a wind path.

  That is, since the rotating shaft 8a of the air blowing means is provided in parallel with the rotating shaft 5a of the humidifying filter, the motor-side space portion 9a is provided in the central portion of the humidifying filter 5 on the leeward side, Since the first outer suction space portion 9b and the second outer suction space portion 9c are provided in the part, the air is sucked by the air blowing means 8 from the central portion on the leeward side and the both end portions of the humidifying filter 5. As a result, the air flows more uniformly in the entire humidification filter 5, so that the humidification ability can be improved.

  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. Is greater than the horizontal distance. Specifically, the distance in the horizontal direction of the motor-side space portion 9a, which is the air path between the first blade 8c and the second blade 8d, is the both outer sides of the first blade 8c and the second blade 8d. This is larger than the distance in the horizontal direction between the first outer suction space portion 9b and the second outer suction space portion 9c, which is the air path between the main body case 3 and the main body case 3.

  That is, the air is sucked by the air blowing means 8 from the central portion and the both end portions of the humidifying filter 5, but the humidifying filter 5 is interposed between the both side surface portions of the humidifying filter 5 and the side surface portion of the main body case 3. Since the space is provided to rotate, the air flows into the first blade 8c or the second blade 8d mainly from the first outer suction space portion 9b and the second outer suction space portion 9c through this space. Air can flow. Here, the distance in the horizontal direction of the motor-side space portion 9a, which is the air path between the first blade 8c and the second blade 8d, is defined as the first outer suction space portion 9b and the second outer suction space portion. By increasing the amount of air that is sucked from the motor-side space 9a, which is the air path between the first blade 8c and the second blade 8d, by increasing the distance in the horizontal direction of 9c, the humidifying filter 5 The amount of air passing through the central portion is increased, and the amount of air passing through the space because the humidifying filter 5 rotates, that is, the amount of air not passing through the humidifying 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 sides | surfaces 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-shaped 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.

When the air is blown, since the distance from the humidifying filter 5 to the blowing means 8 is short, the air path resistance from the humidifying filter 5 to the blowing means 8 can be reduced.

  Further, the length of the humidifying filter 5 in the rotation axis direction is longer than the length from the outer side surface of the first casing 8e, which is the air blowing means 8, to the outer side surface of the second casing 8f. Specifically, the length of the humidifying filter 5 in the rotation axis direction is longer than the length from the first outer suction port 8h of the first casing to the second outer suction port 8j of the second casing.

  Thus, the first outer suction space portion 9b, which is a space between the first outer suction port 8h of the first casing and one side surface of the main body case 3, and the second outer suction of the second casing. Since the humidifying filter 5 is also provided at a position facing the second outer suction space portion 9c that is a space between the mouth 8j and the other side surface of the main body case 3, the humidifying filter 5 is connected to the first outside suction space portion 9c. The flow of air to the first outer suction port 8h of the casing and the second outer suction port 8j of the second casing is substantially straight, and the air flow can be made smooth.

  Further, the air inlet 1 is configured to be located between the humidifying means and the air blowing means 8 on the back side of the main body case 3. Specifically, the main body case 3 has a substantially cubic shape and is provided with a substantially horizontally long air inlet 1 on the side surface on the back side, and the upper edge that is the upper edge of the opening of the air inlet 1 is the first casing. 8e and the lower end of the second casing 8f overlap with the side surface of the main body case 3 on the back side, and the lower end edge that is the lower end edge of the opening of the intake port 1 is the height of the rotating shaft 5a of the humidifying filter. Is almost the same height.

  As a result, the air sucked from the air inlet 1 by the air blowing means 8 flows to the humidifying filter 5 slightly downward from the air inlet 1 along the lower surfaces of the first casing 8e and the second casing 8f. The air also flows through the humidifying filter portion lower than the rotating shaft 5a, and as a result, the air flows substantially uniformly throughout the humidifying filter 5 and the humidifying ability can be improved.

  The first blade 8c and the second blade 8d are sirocco fans having the same shape. Specifically, the first blade 8c and the second blade 8d are both-suction type sirocco fans, and a disc-shaped main plate portion and a rotation shaft of the electric motor 8b are inserted in the central portion of the main plate portion. A substantially cylindrical shaft fixing portion is provided, and a plurality of arc-shaped blade portions extending from both surfaces of the main plate portion are provided on the outer peripheral portion 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 rotating shaft 8a of the blower means, 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 at the top, and a tongue piece is provided on the front side of the main body case 3 of the discharge port. 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, and a curved portion in which the periphery of the suction port curves inwardly of the casing. The upper part is provided with a substantially rectangular discharge port. A tongue piece is provided on the front side of the main body case 3 of the discharge port. Thereby, the air sucked from the suction ports of the first casing 8e and the second casing 8f passes from the discharge 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. Can blow out. As a result, when the operation is performed with the back side of the main body case 3 facing at a position close to 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. This can be suppressed.

  As described above, the present invention includes a main body case having an intake port and an exhaust port, and humidifying means provided in the main body case. The humidifying means includes a water tank containing a certain amount of water, and water in the water tank. A cylindrical humidifying filter having a part of the periphery immersed therein, a rotating means for rotating the humidifying filter, a water supply tank for supplying water to the water tank, and a rotating shaft of the blowing means for rotating the humidifying filter. It is provided in parallel with the shaft, and the humidifying filter is provided on the upstream side of the air blowing means for sending air from the intake port to the exhaust port, so that the humidifying ability can be improved.

  In other words, the rotation axis of the air blowing means is provided in parallel with the rotation axis of the humidifying filter, and the humidifying filter is provided upstream of the air blowing means for blowing air from the intake port to the exhaust port. The air sucked into the means is blown out into the room from the blower means through the exhaust port. That is, since the downstream side of the humidifying filter is brought into a negative pressure state by the air blowing means, the air sucked from the intake port on the upstream side of the humidifying filter flows almost uniformly into the entire humidifying filter.

  According to these results, the air flows almost uniformly throughout the entire humidifying filter, so that the humidifying ability can be improved.

  Therefore, it is expected to be utilized as a humidifier for home use or office use.
