  The humidifying device according to claim 1 of the present invention includes a blower that blows air to a ventilation passage that is formed by communicating a suction port and a blower outlet provided in a main body, and a plurality of branches in an upstream side of the blower in the ventilation passage. A humidifying flow path, a plurality of humidifying filters rotatably provided in the humidifying flow path, a water tank for immersing the lower end portion of the humidifying filter and supplying water, and a rotary motor for rotating the humidifying filter. When the room air sucked into the main body from the suction port by the blower passes through the ventilation path, is branched into a plurality of humidification channels on the way, and passes through the humidification filter arranged in each humidification channel The humidified air is supplied to the blower provided above the humidifying filter, and blown into the room from the air outlet provided at the upper part of the main body. The room air sucked into the main body is To multiple To pass each of the humidifying filter in Toki been humidified flow path, an effect that the passing wind velocity is reduced, the pressure loss can be greatly reduced as compared with the conventional humidifier.

  The ventilation path from the suction port to the humidifying filter is formed by the curved portion of the casing of the blower, and the main body of the humidifying device is on the one rotating shaft 7a side of the cylindrical humidifying filter and the humidifying filter. Since the outer wall of the scroll of the blower can be used as a flow path as a flow path for distributing a suction port above the suction port to the plurality of humidification filters, a flow path for circulating the blown air is separately provided. There is no need, and the inside of the main body has a simple structure and the appearance can be reduced in size.

  The blower includes a casing having a pair of air inlets on both side walls, both suction fans housed in the casing, and a drive motor that rotates the both suction fans, and each of the suction fans has one support circle.

In addition, an air volume / air direction control plate is arranged in a C shape in the heating section, and the heated intake air flow is divided into two directions, so that the air flow to each humidifying filter is distributed almost evenly and humidified in a balanced manner. It has the effect that the function can be fully exerted.

  In addition, the upper side surface of the main body is formed with a flat or curved surface that slopes inward, and the outlet-side humidification passage leading to the air intake of the blower has a tapered cross section.

The ventilation path 4 of the main body 1 is provided with a blower 5, and the ventilation path 4 from the suction port 2 to the blower 5 is branched into two humidification channels 6 in the middle, and each humidification channel 6 has a cylindrical humidification The filter 7 is provided by a rotary motor 9 so as to be rotatable around a horizontal rotation shaft 7a. A water tank 8 that immerses the lower end of the humidification filter 7 is provided below the humidification filter 7, and a water supply tank 8 a is placed on the water tank 8.

  In addition, a part of the air path from the suction port 2 of the humidification channel 6 to the humidification filter 7 is formed by the curved portion 10a on the outer periphery of the casing 10 that forms the spiral shape of the blower 5, and extends along the curved portion 10a. Introduced below.

  Moreover, the casing 10 of the blower 5 includes a pair of air inlets 10b on both side walls and is connected to the two humidifying channels 6 respectively. Both suction fans 11 are accommodated in the casing 10, and a drive motor 5 a that rotates both suction fans 11 is supported so as to cross one intake port 10 b of the casing 10. Both suction fans 11 are formed by arranging a first blade row 11b and a second blade row 11c on both surfaces of one support disk 11a.

  Further, by rotating the rotation directions of the two humidifying filters 7 opposite to each other and adjusting the air volume so that the blade length of the first blade row 11b provided on the drive motor 5a side is larger than the blade length of the second blade row 11c. The air volumes of the humidifying channels 6 are made substantially the same.

  With the above configuration, when the indoor air sucked into the main body 1 from the suction port 2 by the blower 5 is branched into the two humidification channels 6 on the way and passes through the humidification filters 7 arranged by the respective humidification channels 6. Moisture is supplied to the air to form humidified air, and this humidified air is introduced into the blower 5 provided above the humidifying filter 7 and blown into the room through the air outlet 3 provided at the upper part of the main body 1. Thus, since the indoor air sucked from the suction port 2 of the main body 1 passes through each humidifying filter 7 in the humidifying flow path 6 branched into a plurality, the passing air speed becomes small, and the pressure loss is the conventional one. Compared to a humidifier, it can be greatly reduced.

  Moreover, the main body 1 of the humidifier is provided with a suction port 2 on the one rotating shaft 7 a side of the cylindrical humidification filter 7 and above the humidification filter 7, and flows from the suction port 2 to the plurality of humidification filters 7. Since the curved portion 10a of the outer wall of the casing 10 of the blower 5 can be used as the ventilation path 4 for the purpose, there is no need to separately provide a flow path for circulating the blown air, the inside of the main body 1 has a simple structure, and the appearance The shape can be reduced.

  Further, since both the suction fans 11 are formed with the first blade row 11b and the second blade row 11c on both sides of the support disk 11a, the humidified air that has passed through the plurality of humidifying filters 7 is a pair of intake air on both sides. Since the air is sucked into the casing 10 having the opening 10b and can be blown into the room through one outlet 3 provided in the main body 1, the humidified air is supplied to the two humidifying channels 6 by one blower 5. Can be circulated, the humidification function can be improved, the number of parts can be reduced, and the shape of the main body 1 can be reduced.

As shown in FIG. 4, when the rotation directions of the humidifying filters 7 are the same, the moisture retention state of the humidifying filters 7 is different and a difference in ventilation resistance is caused. Therefore, the partition plate on the side where the humidifying filters 7 rise from the water surface By changing the tip position of 12b, the inlet-side humidification flow path 6A is relatively widened.

  Also, an inlet-side humidified flow is provided between two partition plates 12a and 12b that are provided with a suction port 2 on one side of the rotating shaft 7a of each humidifying filter 7 and formed in an oblique direction along the outer periphery of the humidifying filter 7.

It can be demonstrated.

  Moreover, by providing the 2nd wind direction control board 14a, 14b comprised by the some thin plate in the exit side humidification flow path 6b vicinity, the humidified air which passed the humidification filter 7 can be smoothly guided to the air blower 5. Therefore, pressure loss can be reduced.

  In addition, by providing the heating unit 15 in the inlet-side humidification flow path 6a, the room air sucked from the suction port 2 is heated when passing through the heating unit 15 to reduce the relative humidity, and the surface of the humidification filter 7 The temperature is increased to promote the evaporation of moisture, and when the heated airflow passes through the humidifying filter 7, the amount of moisture vaporized from the humidifying filter 7 increases, and a large amount of humidified air can be obtained. Further, by arranging the air volume / air direction control plate 16 in the shape of a letter C in the heating unit 15 and dividing the heated intake air flow into two directions, the air flow to each humidifying filter 7 is substantially evenly distributed, The humidification function can be fully exerted in a balanced manner.
