JP 2010-196959 A

According to the humidifying device described in Patent Document 1, since the blower fan in the case blows air toward the discharge port, the humidified air is discharged from the discharge port to the outside of the case.
In Patent Document 1, a propeller-like blower fan (hereinafter referred to as a propeller fan) is depicted as a blower fan. In the air blowing by the propeller fan, a difference in the air volume tends to occur between the rotation center portion and the rotation edge portion of the propeller fan. For this reason, in the conventional humidifier, at the exhaust port, a difference in air volume tends to occur between a portion facing the rotation center of the propeller fan and a portion facing the rotation edge of the propeller fan. For this reason, in the conventional humidifier, a difference is easily generated in the humidity of the air discharged by the part of the exhaust port.
Thus, in the conventional humidifier, there exists a subject that it is difficult to raise the effect of humidification.

  SUMMARY An advantage of some aspects of the invention is to solve at least a part of the problems described above, and the invention can be implemented as the following forms or application examples.

Embodiments will be described with reference to the drawings.
The humidifier 1 in this embodiment has the housing | casing 3, the water supply tank 5, the humidification unit 7, and the air blower 9, as shown in FIG. The water supply tank 5, the humidification unit 7, and the blower 9 are each accommodated in the housing 3.
Water 6 is stored in the water supply tank 5. The water 6 stored in the water supply tank 5 is supplied to the humidification unit 7.
The humidification unit 7 converts the water 6 supplied from the water supply tank 5 into steam 8.
The blower 9 has a blower fan 10. The blower 9 can blow air by rotating the blower fan 10. In the present embodiment, a propeller fan is employed as the blower fan 10.

The inside of the housing 3 is partitioned into two rooms, a humidification chamber 11 and a blower chamber 13. The humidifying chamber 11 and the air blowing chamber 13 communicate with each other through a vent hole 15. The humidification chamber 11 is provided with an intake hole 17. The humidification chamber 11 communicates with the outside of the housing 3 through the intake hole 17. In addition, an exhaust hole 19 is provided in the blower chamber 13. The air blowing chamber 13 communicates with the outside of the housing 3 through the exhaust hole 19.
The water supply tank 5 and the humidification unit 7 are accommodated in the humidification chamber 11. The blower 9 is accommodated in the blower chamber 13.

A pre-filter 21 is provided in the intake hole 17. The intake hole 17 is covered with a prefilter 21.
A pre-filter 23 is provided in the vent hole 15. The vent hole 15 is covered with a prefilter 23.
A hepa filter 25 is provided in the exhaust hole 19. The exhaust hole 19 is covered with a hepa filter 25.
In the humidifier 1, the blower 9 blows air from the blower chamber 13 toward the exhaust hole 19. Thereby, the gas (air in this embodiment) in the blower chamber 13 is exhausted from the exhaust hole 19 to the outside of the housing 3 through the hepa (HEPA (High Efficiency Particulate Air) filter 25.

At this time, the air pressure in the air blowing chamber 13 becomes lower than the air pressure outside the housing 3 with the exhaust from the exhaust hole 19. For this reason, with the exhaust from the exhaust hole 19, the gas in the humidification chamber 11 flows into the blower chamber 13 from the vent hole 15 through the prefilter 23.
As the gas flows from the humidifying chamber 11 into the blower chamber 13, the pressure inside the humidifying chamber 11 becomes lower than the pressure outside the housing 3. For this reason, with the inflow of gas from the humidifying chamber 11 to the air blowing chamber 13, the gas outside the housing 3 flows into the humidifying chamber 11 from the intake hole 17 through the prefilter 21.
That is, in the humidifier 1, when the blower 9 is driven, the gas outside the housing 3 is sucked into the humidifying chamber 11 from the intake hole 17, and the gas sucked into the humidifying chamber 11 passes through the vent hole 15 and the blower chamber 13. In this order, the air is exhausted from the exhaust hole 19 to the outside of the housing 3.

When the gas outside the housing 3 is sucked into the humidification chamber 11 from the intake hole 17, the gas outside the housing 3 is purified by the pre-filter 21 and then sucked into the humidification chamber 11.
Further, when the gas in the humidifying chamber 11 flows into the blower chamber 13 from the vent hole 15, the gas in the humidifying chamber 11 flows into the blower chamber 13 after being purified by the prefilter 23.
Similarly, when the gas in the blower chamber 13 is exhausted from the exhaust hole 19 to the outside of the housing 3, the gas in the blower chamber 13 is purified by the hepa filter 25 and then exhausted to the outside of the housing 3.
As described above, the humidifying device 1 can send clean gas out of the housing 3. For this reason, the humidification apparatus 1 has a function as what is called a fan filter unit (FFU).

Here, in the humidifier 1, the humidification unit 7 is provided in the humidification chamber 11.
The humidifying unit 7 has a heater 27. The heater 27 generates heat when supplied with electric power. The humidification unit 7 generates steam 8 from the water 6 by the heat of the heater 27.
The steam 8 generated by the humidification unit 7 is mixed in the humidification chamber 11 with the gas sucked into the humidification chamber 11 from the outside of the housing 3. That is, in the humidifier 1, the gas is humidified in the humidification chamber 11. The gas humidified in the humidification chamber 11 flows into the blower chamber 13 through the vent hole 15 and is then exhausted out of the housing 3 through the exhaust hole 19.
As described above, the humidifying device 1 can send out a humidified clean gas to the outside of the housing 3. For this reason, the humidifier 1 also has a function of reducing the generation of static electricity in the surrounding environment.

Here, in this embodiment, as shown in FIG. 1, a partition plate 31 and a plurality of guide plates 33 are provided in the air blowing chamber 13.
The partition plate 31 is provided between the blower 9 and the exhaust hole 19. A gap is provided between the partition plate 31 and the blower 9.
The plurality of guide plates 33 are respectively provided on the inner wall 35 of the housing 3. Each guide plate 33 extends from the inner wall 35 toward the inside, that is, toward the rotation center 37 of the blower fan 10. Each guide plate 33 is provided in a state of being inclined in a direction approaching the exhaust hole 19 from the inner wall 35 toward the inside. For this reason, each of the plurality of guide plates 33 can be regarded as being positioned between the partition plate 31 and the exhaust hole 19. A gap is provided between each guide plate 33 and the partition plate 31.

The partition plate 31 has a size that covers the blower fan 10 of the blower 9 as shown in FIG. 2, which is a cross-sectional view taken along line AA in FIG. 1. The partition plate 31 is provided at a position overlapping the blower fan 10 in a plan view, and is provided in an area that covers the blower fan 10.
A gap is provided between the partition plate 31 and the inner wall 35 of the housing 3. For this reason, the gas blown toward the partition plate 31 from the blower 9 can flow through the gap between the partition plate 31 and the inner wall 35 to the exhaust hole 19 (FIG. 1) side of the partition plate 31.
In the present embodiment, two guide plates 33 are employed as the plurality of guide plates 33. As shown in FIG. 2, the two guide plates 33 are provided at positions facing each other with the blower fan 10 interposed therebetween. In the present embodiment, a gap is provided between each guide plate 33 and the partition plate 31 in plan view.

In the humidifying device 1 having the above configuration, when the blower fan 10 of the blower 9 is driven, at least a part of the blown air from the blower fan 10 hits the partition plate 31. As shown in FIG. 1, the air blown on the partition plate 31 is directed outward from the rotation center 37 of the blower fan 10, that is, from the partition plate 31 toward the inner wall 35. At least a part of the air flow from the partition plate 31 toward the inner wall 35 is guided by the two guide plates 33 toward the exhaust hole 19 side of the partition plate 31 and toward the rotation center 37 side of the blower fan 10.
As described above, in the humidifier 1, the air blown from the blower fan 10 is discharged from the exhaust hole 19 through the partition plate 31, the guide plate 33, and the hepa filter 25. Thereby, it can be made easy to avoid that the ventilation from the blower fan 10 directly goes out of the housing 3 through the exhaust hole 19.

Here, in the configuration in which the air blown from the blower fan 10 directly goes out of the housing 3 from the exhaust hole 19, a difference occurs in the wind pressure 38 depending on the portion of the exhaust hole 19 as shown in FIG. Cheap. In FIG. 3, the height of the wind pressure 38 is expressed by the length of the arrow. In FIG. 3, the length of the arrow becomes longer as the wind pressure 38 is higher.

In the configuration in which the air blown from the blower fan 10 directly goes out of the housing 3 from the exhaust hole 19, the wind pressure 38 tends to decrease as the air blower 10 approaches the rotation center 37 side of the blower fan 10. .

  On the other hand, in this embodiment, since the air from the blower fan 10 is discharged from the exhaust hole 19 through the partition plate 31, the guide plate 33, and the hepa filter 25, the air from the blower fan 10 is directly received. Further, it can be easily avoided that the exhaust hole 19 goes out of the housing 3. As a result, in the present embodiment, as shown in FIG. 3B, the exhaust hole 19 includes a portion facing the rotation center 37 of the blower fan 10 and a portion facing the rotation edge 39 of the blower fan 10. The difference in the wind pressure 38 between them can be reduced. Thereby, the air volume exhausted from the exhaust hole 19 can be easily uniformed over the exhaust hole 19. For this reason, the humidity of the gas exhausted from the exhaust hole 19 can be easily made uniform over the exhaust hole 19. Therefore, the humidification effect can be easily enhanced.

In the present embodiment, the intake hole 17 corresponds to the introduction port, the exhaust hole 19 corresponds to the discharge port, the housing 3 corresponds to the container, the humidification unit 7 corresponds to the water vapor generation unit, and the blower fan 10 is the propeller. Corresponding to the fan, the partition plate 31 corresponds to the receiving member, and the guide plate 33 corresponds to the guide member.
In the present embodiment, the humidity of the gas exhausted from the exhaust hole 19 can be easily uniformed over the entire exhaust hole 19, so that the humidification effect can be easily enhanced.
Here, the humidifier 1 can be utilized as a device for locally preventing charging. When the humidifier 1 is used as a device for preventing local charging, it is ideal from the viewpoint of antistatic that the humidity of the gas exhausted from the exhaust hole 19 is uniform throughout the exhaust hole 19. . According to the humidifier 1, the humidity of the exhausted gas can be easily made uniform throughout the exhaust hole 19. Therefore, when the humidifier 1 is used for local antistatic, the antistatic effect can be easily enhanced. can do.
