JP 2011-122788 A

  In the conventional humidifier, since the motor 73 for rotating the filter 74 is fixed to the member 72 that constitutes a part of the ventilation path 7 whose end is the air outlet 71, the motor 73 is driven. The noise which propagates propagates through the ventilation path 7, and leaks out from the blower outlet 71 outside. For this reason, there is a problem that the humidifier is noisy.

  This invention is made | formed in view of such a situation, The place made into the objective is to provide the humidification apparatus which reduced the noise by improving arrangement | positioning of a motor.

Features.

  In the present invention, the vibration of the motor for rotating the filter member is difficult to propagate to the ventilation path, and the noise caused by the vibration of the motor leaking from the air outlet is reduced. Therefore, there is an effect that the humidifier can be quieted.

It is a disassembled perspective view of a humidifier. It is a typical sectional side view which shows schematic structure of a humidifier. It is a perspective view of a humidification filter unit. It is a typical sectional side view of the humidifier which emphasized the partition member and the partition member. It is typical sectional drawing which shows the structural example of the conventional humidifier.

  Hereinafter, the present invention will be specifically described with reference to the drawings showing embodiments thereof.

  FIG. 1 is an exploded perspective view of the humidifier, and FIG. 2 is a schematic side sectional view showing a schematic configuration of the humidifier. FIG. 2 shows the front as left and the back as right, and FIG. 1 is a perspective view seen from the back side (right side of FIG. 2). In the following description, the front side is the front and the back side is the rear. The humidifier includes a blower 6, a humidifying filter unit 3, and a water tank 4 inside a vertically long rectangular box-shaped housing. As shown in FIG. 2, the interior of the housing is divided by a partition member 12 into a rear suction chamber 2 and a front ventilation path 1. The suction chamber 2 communicates with the outside through a number of suction ports 25 provided in the rear panel 24 of the housing. The ventilation path 1 communicates with the outside through an air outlet 11 provided in the top plate of the housing. The terminal end of the ventilation path 1 is a blower outlet 11, and the partition wall member 12 is a member constituting a part of the ventilation path 1. The suction chamber 2 and the ventilation path 1 are communicated with each other through a large number of ventilation holes provided in the lower part of the partition wall member 12.

As shown in FIG. 1, the rear panel 24 is detachable, and a deodorizing filter 23 and a dust collection filter 22 are stacked on the front side of the rear panel 24. The deodorizing filter 23 is formed by, for example, dispersing and holding activated carbon in a non-woven fabric, and acts to adsorb and remove odorous components during ventilation. The dust collection filter 22 is, for example, a known HEPA (High Efficiency Pa
It is an rticulate air filter, and acts to collect and remove fine dust contained in the air. A plate-like partition member 21 that partitions the suction chamber 2 is disposed on the front side of the dust collection filter 22. A large number of ventilation holes are formed in the partition member 21, and air passes therethrough. The partition member 21 is fixed in the humidifier. The deodorizing filter 23 and the dust collection filter 22 are integrated separately into a rectangular frame made of synthetic resin, and are fitted between the partition member 21 and the rear panel 24.

  The blower 6 includes an impeller 60 and a motor 61 that drives the impeller 60. The motor 61 is fixed in the ventilation path 1, and the impeller 60 is connected to the rotation shaft of the motor 61 and is arranged to face a large number of ventilation holes provided in the lower part of the partition wall member 12. The impeller 60 is rotated by driving the motor 61, and the blower 6 sucks air from the direction of the rotation axis and sends out the air in the centrifugal direction. By the operation of the blower 6, air flows from the outside into the suction chamber 2 through the suction port 25 of the rear panel 24 as indicated by the white arrow in FIG. 2. The inflowed air flows forward through the suction chamber 2 through the ventilation holes of the partition member 21, is sucked into the blower 6 through the ventilation holes in the lower part of the partition wall member 12, and changes the direction upward to change the direction of the ventilation path 1. It is led out to the inside and discharged to the outside through the air outlet 11.

  Thus, air flows through the suction chamber 2 and the ventilation path 1 inside the housing according to the operation of the blower 6. The deodorizing filter 23 and the dust collecting filter 22 are located on the upstream side of the air flow, and the air introduced into the suction chamber 2 through the suction port 25 is removed of odor components by passing through the deodorizing filter 23. The dust is removed by passing through the dust collection filter 22. The deodorizing filter 23 and the dust collecting filter 22 correspond to the air cleaning filter in the present invention. The humidifier also functions as an air cleaner by the deodorizing filter 23 and the dust collection filter 22.

  The humidifying filter unit 3 and the water tank 4 are disposed between the partition member 21 and the blower 6 in order to humidify the air that has flowed into the humidifying device. The humidifying filter unit 3 is configured by storing and holding a humidifying filter (filter member) 31 inside a holding frame 30 having a hollow disk shape. The humidifying filter 31 is formed in a flat plate shape by folding a sheet made of a material that has water absorbability such as rayon and can be ventilated into a bellows shape, and is housed inside the holding frame 30. The humidification filter 31 corresponds to the filter in the present invention. The shape of the humidifying filter 31 housed inside the holding frame 30 is a shape that lacks a part of the disk. FIG. 3 is a perspective view of the humidifying filter unit 3. In FIG. 3, the front side of the humidification filter unit 3 is shown with the perspective view. In FIG. 3, the holding frame 30 of the humidifying filter unit 3 is illustrated, and the humidifying filter 31 held by the holding frame 30 is omitted. On the outer peripheral surface of the holding frame 30, a ring gear portion 32 having an appropriate width in which teeth are formed over the entire circumference in the central portion in the width direction is integrally provided.

  The water tank 4 has a rectangular deep dish shape and is placed on the bottom plate of the housing. The upper surface of the water tank 4 is opened, and the humidifying filter unit 3 is disposed on the upper side of the water tank 4. The lower part of the humidification filter unit 3 enters from the upper side of the water tank 4 and is located inside the water tank 4. In the state where the humidifying filter unit 3 is disposed on the water tank 4, the humidifying filter 31 is substantially vertical. Water is supplied to the water tank 4 from the tank 41 so as to keep the water level constant.

  The humidifier is provided with a drive motor 5 for rotationally driving the humidification filter unit 3. The drive motor 5 corresponds to the motor in the present invention. The drive motor 5 is fixed to the partition member 21 and is disposed above the humidifying filter unit 3. The partition member 21 corresponds to the fixing member in the present invention. A transmission gear (gear) (not shown) is connected to the drive motor 5, and a drive gear (gear) (not shown) is engaged with the transmission gear. The ring gear portion 32 of the humidifying filter unit 3 is meshed with the drive gear. When the drive motor 5 is driven, the drive gear is rotated via the transmission gear, and the rotation of the drive gear is transmitted to the holding frame 30 via the ring gear portion 32, so that the humidifying filter unit 3 maintains the position shown in FIG. However, it rotates in the vertical direction shown in FIG.

  The lower portion of the rotating humidifying filter unit 3 is submerged in the water tank 4, and the peripheral portion of the humidifying filter 31 is intermittently submerged while rotating. The water in the water tank 4 is sucked up by the humidifying filter 31 and lifted by the rotation of the humidifying filter unit 3. Water absorption is performed from the peripheral portion of the humidifying filter 31 toward the central portion, and the humidifying filter 31 contains water. The air flowing through the suction chamber 2 by the operation of the blower 6 passes through the humidifying filter 31 containing water. When the air passes through the humidifying filter 31, water contained in the humidifying filter 31 is vaporized, and the air becomes air containing the vaporized water. Air containing moisture is sucked into the blower 6, flows through the ventilation path 1, and is discharged from the air outlet 11 to the outside of the humidifier. In this way, the humidifier humidifies external air. Moreover, the air which passed the humidification filter 31 flows through the ventilation path 1. When humidification is not performed, the humidifier stops the humidification filter unit 3 at a position where the humidification filter 31 having a shape lacking a part of the disk does not submerge. In this state, the humidification filter 31 does not absorb water, so humidification is stopped. When air cleaning is not performed, the humidifier stops the blower 6.

  FIG. 4 is a schematic side cross-sectional view of the humidifying device in which the partition member 12 and the partition member 21 are emphasized. In FIG. 4, the partition member 12 and the partition member 21 are highlighted in black. As described above, the drive motor 5 is fixed to the partition member 21 and is not attached to a member constituting the ventilation path 1 such as the partition wall member 12. For this reason, the vibration of the drive motor 5 is not directly transmitted to the members constituting the ventilation path 1. Further, the partition member 21 to which the drive motor 5 is fixed is separated from the partition member 12 constituting a part of the ventilation path 1. Since the member to which the drive motor 5 is fixed is separated from the member constituting the ventilation path 1, the vibration of the drive motor 5 is not easily transmitted to the member constituting the ventilation path 1. Since the vibration of the drive motor 5 is not easily transmitted to the members constituting the ventilation path 1, the noise caused by driving is difficult to propagate through the ventilation path 1, and the noise leaking from the air outlet 11 is reduced.

  An experiment was performed to compare noise between the conventional humidifier and the humidifier according to the present embodiment. In the conventional humidifier, the drive motor is attached to the partition member constituting a part of the ventilation path, and the humidifier according to the present embodiment has the drive motor attached to the partition member 21 as described above. A noise meter was attached to both outlets, and the noise when the drive motor alone was operated without operating the blower was measured with the noise meter. The measured value of noise in the conventional humidifier is 45 dB, and the measured value of noise in the humidifier according to the present embodiment is 38 dB. That is, the present invention makes it possible to reduce noise exceeding 5 dB. Therefore, it is possible to reduce the noise of the humidifier while maintaining the humidifying and air cleaning capabilities of the humidifier.

  In the humidifying device according to the present embodiment, the drive motor 5 is fixed to the partition member 21 on the windward side of the humidifying filter unit 3. In the conventional humidifier, since the drive motor is disposed on the leeward side of the humidification filter unit, there is a possibility that water transmitted through the holding frame or scattered water enters the drive motor along the air flow. In the present embodiment, since the drive motor 5 is arranged on the windward side compared to the conventional case, it is difficult for water to enter the drive motor 5 as compared with the conventional case, and deterioration of the drive motor 5 is suppressed.

  In addition, the internal structure of the humidification apparatus shown in FIG.2 and FIG.4 is an example, and the form which has another structure may be sufficient as a humidification apparatus. For example, the drive motor 5 may be fixed to a member other than the partition member 21 as long as the drive motor 5 is fixed to a member different from the members constituting the ventilation path 1. Further, the drive motor 5 may be fixed to a member that is in contact with a member constituting the ventilation path 1. In this embodiment, the effect of reducing the noise is slightly reduced as compared with the embodiment in which the drive motor 5 is fixed to a member separated from the member constituting the ventilation path 1, but the drive motor is included in the member constituting the conventional ventilation path. Compared to a fixed humidifier, noise can be reduced sufficiently. Moreover, the ventilation path 1 may be comprised by the combination of many members rather than the structure shown in FIG.2 and FIG.4. Moreover, the air blower 6 may be arrange | positioned in positions other than the position shown in FIG.2 and FIG.4.

  Further, in the present embodiment, the mode in which the humidifying filter 31 is rotated using the ring gear portion 32 provided on the outer peripheral surface of the holding frame 30 has been shown. However, the humidifier is provided coaxially on one surface of the holding frame 30. The form which rotates the humidification filter 31 using the cyclic | annular gear part formed may be sufficient. Moreover, in this Embodiment, although the form which absorbs water when a part of humidification filter 31 was immersed was shown, the humidification apparatus may be the form which absorbs water, without being immersed in a humidification filter. For example, the form provided with the mechanism which supplies water to the humidification filter which rotates may be sufficient as a humidifier. In addition, for example, the humidifying device may have a form in which a member for pumping water from the water tank along with the rotation and placing it on the humidifying filter is provided in the humidifying filter unit.
