JP 2003-35443 A

  As in Patent Document 1, a humidifying filter of a type that sucks up water in a water tank is treated with a surfactant in order to obtain a moisture absorbing effect. Dissolve in water. When the ventilation path of the humidifying filter is small and a water film is formed on the water surface of the water tank on the air outlet side of the humidifying filter, the melted surfactant is blown on the air outlet side of the humidifying filter by the air passing through the humidifying filter. There is a risk of foaming.

  Moreover, even if the ventilation path of the humidifying filter is relatively large, in order to promote the humidifying effect, when the rotational speed of the blower is increased to a strong blowing state, the lower part of the humidifying filter is immersed in the water of the aquarium Therefore, the static pressure on the air inlet side of the humidifying filter is increased, and the water level of the water tank on the air outlet side of the humidifying filter may be slightly higher than the water level on the air outlet side of the humidifying filter. For this reason, the ventilation path becomes small in the portion on the air outlet side of the humidifying filter, a water film is stretched on the water surface, and the strong air passing through the humidifying filter causes the melted surfactant to dissolve the air in the air outlet side of the humidifying filter. There is a risk of foaming.

  Such foaming is small and causes no problem when the foam can be directly blown, but if the foam accumulates gradually and the inside of the humidifier becomes wet, there is a risk that mold will form in that portion. In addition, if such bubbles overflow to the outside of the water tank, there is a possibility that the installation peripheral portion of the humidifier becomes wet.

  Therefore, in view of such a point, the present invention does not cause foaming on the air outlet side of the humidifying filter even when the rotational speed of the blower is increased to be in a strong air blowing state in order to promote the humidifying effect. It aims at providing a simple humidifier.

Therefore, in the first invention, a water tank is provided at the lower part of the humidifier body, and a blower and a humidifying filter in which the lower part is immersed in the water of the water tank are disposed in the ventilation path communicating the suction port and the blowout port, humidification filter has a large number of vent paths blown from the blower passes in the humidifier to humidify the ambient air by the blower to pass through the air passage of the humidifying filter, foaming at the blower outlet side of the humidifying filter In order to prevent this, the air passage of the humidifying filter is formed so as to be inclined so that the air outlet side is located above the inlet side, and enters the air passage from the air inlet side at the same level as the water surface of the water tank. Air is sent from the air outlet side away from the water surface .

The second invention is a humidifier in the lower portion of the main body is provided a water tank, a humidification filter bottom is immersed in water of the blower and the water tank to the ventilation path communicating the suction port and blow port is disposed, the humidification filter has a large number of vent paths blown from the blower passes in the humidifier to humidify the ambient air by the blower to pass through the air passage of the humidifying filter, preventing foaming at the blower outlet side of the humidifying filter In order to accomplish this, the humidifying filter has a filter block in which a flat cloth body and a wavy cloth body are alternately overlapped to form an air passage, and is stored so as to surround the filter block. constituted by a frame having the said air passage, thereby forming obliquely with respect to the bottom surface of the water surface and parallel to the filter block, the upper air blowing outlet side than the inlet side of the air passage Formed so as to be located, air entering the air passage from the air inlet side on the same level as the water surface of the water tank, characterized in that it is delivered from the blowing outlet side away from the water surface.

The light beams from the light emitting diodes 31A to 31E are introduced into the vertical bars 33A to 33E through the through holes 32A to 32E to the corresponding vertical bars 33A to 33E, respectively. The vertical bars 33A to 33E are configured to shine.

  In addition, for each pressing operation of the switch 22B, a strong operation in which the blower 8 rotates at a high speed, a medium operation in which the fan 8 rotates at a medium speed, and a weak operation in which a fan rotates at a low speed are performed. And it will switch to an automatic driving | running | working state further by pressing operation of switch 22B once again. Then, as described above, the operation of the blower 8 can be switched to the strong operation, the medium operation, the weak operation, and the automatic operation in order by pressing the switch 22B again.

  Here, in a state where the surfactant contained in the humidifying filter 7 is dissolved in the water tank 6, for example, when the operation of the blower 8 is made to be a strong operation, the strong wind is on the air inlet side of the filter block 7 </ b> B of the humidifying filter 7. It enters more and is sent out from the air outlet side through the air passage 7C, and does not directly hit the water surface, and foaming on the air outlet side of the humidifying filter can be prevented. That is, the air that has entered the air passage 7C from the air inlet side at the same level as the water surface L1 of the water tank 6 moves away from the water surface and does not directly hit the water surface. Therefore, the occurrence of foaming on the air outlet side of the humidifying filter can be prevented.

  Other embodiments will be described below. First, the filter block 7B of the humidifying filter 7 is formed such that the flat cloth body 7B1 and the corrugated cloth body 7B2 are alternately stacked and bonded to form the air passage 7C. The aeration path 7C is formed horizontally parallel to the water surface so that the outlet side and the inlet side are at the same level. That is, the air passage 7C is formed horizontally with respect to the bottom surface of the filter block 7B parallel to the water surface L1. However, as shown in FIG. 6 which is simplified, the filter block 7B is inclined so that the air outlet side is located above the inlet side, and the humidifying filter 7 is placed in the water tank 6 via an attachment member (not shown). Arrange. Thereby, as in the first embodiment, the air that has entered the air passage 7C from the air inlet side that is at the same level as the water surface L1 of the water tank 6 is away from the water surface and does not directly hit the water surface. Since the blowing does not hit the surface of the water in which the surfactant is dissolved, the occurrence of foaming on the blowing outlet side of the humidifying filter can be prevented.
