<Embodiment 1>
A humidifying device 1, a humidifying filter unit 2, and a humidifying filter cover member 22 according to Embodiment 1 will be described with reference to FIGS. 1 to 7. FIG. FIG. 1 is an exploded perspective view showing the configuration of a humidifying device 1 according to Embodiment 1. FIG. FIG. 2 is a cross-sectional view showing the configuration of the humidifying device 1 according to Embodiment 1. As shown in FIG. The left side and the right side of the paper surface of FIG. 2 are the front side and the back side of the humidifying device 1 . FIG. 1 is an exploded perspective view of the humidifying device 1 as seen from the rear side (that is, the right side of the paper surface of FIG. 2). Below, the front side and the back side in the direction perpendicular to the paper surface of FIG.

The humidifier 1 includes a rectangular parallelepiped housing 6 . The housing 6 has a front cover 61, a top cover 62, a rear cover 63, and the like. Further, the housing 6 is provided with a ventilation passage 3 and a water supply space 60 for realizing an air humidification function and an air cleaning function by deodorization and dust collection. That is, the humidifier 1 has an air humidification function and an air cleaning function by deodorization and dust collection. In addition, the humidifier 1 should just be a structure which has an air humidification function at least.

The air passage 3 and the water supply space 60 communicate with each other through a midway opening 33 provided in the middle of the air passage 3 . However, the middle opening 33 is closed by the water tank 12 and a partition plate (not shown) provided in the water tank 12 when the water tank 12 is attached to the housing 6 at a predetermined position. Therefore, air does not flow between the ventilation path 3 and the water supply space 60 during use of the humidifying device 1 .

The water tank 12 is a horizontally long tray with an open top. The water tank 12 is detachably arranged at a predetermined position of the housing 6 so that the longitudinal direction of the water tank 12 coincides with the left-right direction of the humidifier 1 . The water tank 12 includes a first tray 121 and a second tray 122, and the first tray 121 and the second tray 122 communicate with each other through water passage holes (not shown). When the water tank 12 is arranged at a predetermined position in the housing 6 , the first tray 121 is positioned in the air passage 3 and the second tray 122 is positioned in the water supply space 60 .

A humidifying filter unit 2, which will be described later, is attached to the first tray 121. As shown in FIG. A water supply tank 15 is attached to the second tray 122 . A water tap is provided below the water supply tank 15 . The water supply tank 15 is arranged in the water supply space 60 while being attached to the second tray 122 . The water stored in the water supply tank 15 flows out to the second tray 122 and is supplied to the first tray 121 through water passage holes (not shown). As a result, water at a constant water level L is stored in the first tray 121 .

The air passage 3 has a filter housing portion 301 and a blowout passage 302 communicating with each other. In addition, the ventilation passage 3 is provided with a suction port 31 , a blowout port 32 , and an opening 33 in the middle. The suction port 31 opens to the rear cover 63 of the housing 6 . The outside of the humidifying device 1 and the filter accommodating portion 301 communicate with each other through the suction port 31 .

The rear panel 10 is detachably attached to the housing 6 so as to close the suction port 31 . A large number of ventilation holes are formed in the rear panel 10 . The vent is closed by a pre-filter (not shown). The pre-filter collects coarse dust contained in the air flowing into the filter housing portion 301 through the suction port 31 .

The blowout port 32 opens in the top cover 62 of the housing 6 . Via the blower outlet 32, the blower passage 302 and the outside of the humidifier 1 are connected. Air outside the humidifier 1 is sucked into the ventilation passage 3 through the suction port 31 as indicated by an arrow F1 by blowing air from the blower 13, which will be described later. The sucked air flows through the filter housing portion 301 and the blowout passage 302 in this order, and then blows out of the humidifier 1 through the blowout port 32 as indicated by an arrow F2. Note that the outlet 32 may be provided with a louver (not shown). For example, the louver changes the blowing direction so that the air blown from the blowing port 32 can easily rise along the walls of the room.

The blower 13 is arranged at the boundary between the filter housing portion 301 and the blowout passage 302 . The blower 13 is, for example, a sirocco fan and includes a fan motor 131 and a fan 132 . The fan motor 131 is fixed inside the housing 6 . The fan 132 is fixed to the output shaft of the fan motor 131 and rotated by driving the fan motor 131 .

The air purification unit 11 is detachably attached near the suction port 31 of the filter housing unit 301 , that is, on the leeward side of the rear panel 10 . The air that has flowed into the filter housing portion 301 through the suction port 31 passes through the air cleaning portion 11 .

The air purifier 11 includes a dust collection filter 111 and a deodorization filter 112 . The dust collection filter 111 is, for example, a HEPA (High Efficiency Particulate Air) filter, and collects fine dust, pollen, and the like contained in the air passing through the dust collection filter 111 . The deodorizing filter 112 is, for example, a non-woven fabric containing activated carbon, and adsorbs odorous components in the air passing through the deodorizing filter 112 . Therefore, the air that has passed through the air purifier 11 is purified. The air purifier 11 implements an air purifying function.

The first tray 121 of the water tank 12, the humidification filter unit 2, and the rotation drive mechanism 16 are positioned in the filter housing section 301 that exists between the air purification section 11 and the blower 13. As shown in FIG. When the water tank 12 is pulled out of the humidifying device 1 , the humidifying filter unit 2 attached to the first tray 121 is also pulled out of the humidifying device 1 through the intermediate opening 33 .

3 is an exploded perspective view showing the configuration of the humidifying filter unit 2 included in the humidifying device 1 according to Embodiment 1. FIG.

The humidification filter unit 2 has a humidification filter 21 , a humidification filter cover member 22 , a holding frame 23 , and a holding frame cover 24 . Humidification filter 21 and humidification filter cover member 22 are sandwiched between holding frame 23 and holding frame cover 24 . Below, let the direction in which the humidification filter 21 and the cover member 22 for humidification filters are laminated|stacked be the lamination direction S. As shown in FIG. The holding frame 23 corresponds to the first holding member, and the holding frame cover 24 corresponds to the second holding member. The first holding member and the second holding member constitute a holding member.

The holding frame 23 has a cylindrical shape with one end open. A through hole 231 , a reinforcing portion 232 , a waterproof portion 233 , and a positioning rib 235 are formed on one surface of the other end of the holding frame 23 . A sprocket 234 is formed on the outer peripheral surface of the holding frame 23 .

In the illustrated example, one surface of the holding frame 23 is divided into a plurality of pieces (eight pieces in the figure) by the through holes 231 and the reinforcing portions 232 . The shape, position, size, etc. of the through hole 231 and the reinforcing portion 232 are determined so as to maintain the strength of the humidification filter unit 2 and not to hinder the flow of water and air inside and outside the humidification filter unit 2. is designed accordingly.

A waterproof portion 233 is provided on the peripheral portion of one surface of the holding frame 23 . The shape, dimensions, and the like of the waterproof portion 233 are appropriately set so as to prevent water from flowing into the humidifying filter unit 2, as will be described later.

Furthermore, two positioning ribs 235, 235 having a shape projecting in the humidifying filter 21 side, that is, in the stacking direction S are formed on the inner edge of the waterproof portion 233. As shown in FIG. The height of the positioning ribs 235, 235 in the stacking direction S is substantially the same as the height of the humidifying filter 21 in the stacking direction S. Engagement ribs 236 , 236 may be formed at the respective distal ends of the positioning ribs 235 , 235 . The height of the engaging ribs 236, 236 in the stacking direction S is higher than the height of the humidifying filter 21 in the stacking direction S. The engaging ribs 236,236 are part of the positioning ribs 235,235. The positioning ribs 235, 235 and the engaging ribs 236, 236 correspond to protrusions.

The holding frame cover 24 has a substantially rectangular shape. The holding frame cover 24 is attached to the holding frame 23 so as to close the opening side of the holding frame 23 . The mounting structure of the holding frame cover 24 and the holding frame 23 may be arbitrary. The outer shape of the holding frame cover 24 is not limited to the substantially rectangular shape shown in FIG.

A through hole 241 , a reinforcing portion 242 , and a waterproof portion 243 are formed in the holding frame cover 24 . The positions, shapes, dimensions, etc. of the through-hole 241 , the reinforcement part 242 , and the waterproof part 243 are determined by the positions, shapes, dimensions, etc. of the through-hole 231 , the reinforcement part 232 , and the waterproof part 233 formed in the holding frame 23 . corresponds to

Two holding ribs 244 , 244 protruding toward the humidifying filter 21 are formed on the inner edge of the waterproof portion 243 . The restraining ribs 244, 244 correspond to the second protrusions.

Inside the holding frame 23 and the holding frame cover 24, the humidifying filter 21 and the humidifying filter cover member 22 are accommodated and held. However, if the holding frame cover 24 is removed from the holding frame 23 , the humidifying filter 21 and the humidifying filter cover member 22 can be taken out from the holding frame 23 and housed in the holding frame 23 .

The humidifying filter 21 and the humidifying filter cover member 22 are made of a material having water absorption and air permeability. The humidifying filter 21 is configured using, for example, a nonwoven fabric of rayon and PET (polyethylene terephthalate) fibers. The humidifying filter cover member 22 is configured using, for example, a netted body of cotton fibers. Materials for the humidifying filter 21 and the humidifying filter cover member 22 are not limited to these. However, it is preferable that the material of the humidifying filter cover member 22 has higher water absorption and quick-drying properties than the material of the humidifying filter 21 .

The humidifying filter 21 is, for example, a D-cut disc formed by folding a sheet-like nonwoven fabric into a bellows shape. The humidifying filter 21 has a D-cut plane portion 211 . In a state in which humidifying filter 21 is accommodated inside holding frame 23 , planar portion 211 and positioning ribs 235 , 235 are in contact with each other.

The humidifying filter cover member 22 has a body portion 221 and a positioning portion 222 . The main body part 221 has a shape smaller than the size of one surface of the humidification filter 21 and is laminated on one surface of the humidification filter 21 . The positioning portion 222 has a shape extending from at least a part of the edge portion of the main body portion 221 on the same plane. Further, the positioning portion 222 is provided with slits 223 , 223 that engage with the engaging ribs 236 , 236 protruding from the holding frame 23 .

Next, the procedure for assembling the humidifying filter unit 2 will be described with reference to FIGS. 4 to 6. FIG. FIG. 4 is a diagram for explaining the procedure for assembling the humidifying filter unit 2. As shown in FIG. FIG. 5 is a continuation of the procedure for assembling the humidifying filter unit 2. As shown in FIG. FIG. 6 is a partial cross-sectional view of the humidification filter unit 2. FIG.

First, as shown in the perspective view of FIG. 4 , the humidifying filter 21 is accommodated inside the holding frame 23 . In this state, the flat portion 211 of the humidifying filter 21 abuts on the positioning ribs 235 , 235 protruding from the waterproof portion 233 of the holding frame 23 . The flat portion 211 abuts on the positioning ribs 235, 235 so that the humidifying filter 21 is held outside the waterproof portions 233, 243, and the center O21 (see FIG. 4) of the humidifying filter 21 and the center of the holding frame 23 are aligned. and are aligned.

Subsequently, as shown in the perspective view of FIG. 5 , the humidifying filter cover member 22 is laminated on one surface of the humidifying filter 21 . At this time, the positioning portion 222 of the humidifying filter cover member 22 is positioned with respect to the positioning ribs 235 , 235 of the holding frame 23 . In the first embodiment, positioning is performed by engaging the slits 223 provided in the positioning portion 222 with the engaging ribs 236 , 236 that are part of the positioning ribs 235 , 235 . As a result, the center O22 (see FIG. 5) of the humidifying filter cover member 22 and the center of the holding frame 23 are aligned. As a result, the center O22 (see FIG. 5) of the humidifying filter cover member 22 and the center O21 (see FIG. 4) of the humidifying filter 21 are aligned.

Subsequently, the holding frame cover 24 is attached to the holding frame 23 in the state shown in FIG. When the holding frame cover 24 is attached to the holding frame 23, the holding ribs 244, 244 of the holding frame cover 24 come into contact with the positioning portion 222, and the positioning portion 222 is bent toward the humidifying filter 21 side. Since the positioning portion 222 is provided with the cut 224, the positioning portion 222 can be easily bent. As shown in FIG. 6, the bent positioning portion 222 is held between the positioning ribs 235, 235 of the holding frame 23 and the holding ribs 244, 244 of the holding frame cover 24. .

As shown in FIG. 6 , the length of positioning portion 222 is set to be equal to or less than the thickness of humidifying filter 21 . Therefore, even when the positioning portion 222 is bent, it is not submerged in the water stored in the water tank 12 .

The radius of body portion 221 is shorter than the minimum radius of humidifying filter 21 . In other words, the projected area in the stacking direction S of the main body portion 221 is smaller than the projected area in the stacking direction S of the humidifying filter 21 . For this reason, the main body portion 221 of the humidifying filter cover member 22 is concentrically laminated on one surface of the humidifying filter 21 , so that the central portion in the radial direction of the one surface of the humidifying filter 21 is covered with the main body portion 221 . is not covered with the body portion 221 . That is, the peripheral portion of one surface of the humidifying filter 21 is the area where the humidifying filter 21 is exposed. The humidifying filter cover member 22 is not attached to the other surface of the humidifying filter 21 . In other words, the other surface of the humidifying filter 21 is a region where the humidifying filter 21 is entirely exposed.

Next, a support structure for the humidifying filter unit 2 will be described. FIG. 7 is a rear view showing a support structure for the humidifying filter unit 2 according to Embodiment 1. FIG.

Inside the first tray 121, two support rollers 123, 123 are distributed in the horizontal direction. Each rotating shaft of the support rollers 123, 123 is arranged in the front-rear direction.

The humidifying filter unit 2 is detachably mounted on the support rollers 123 , 123 . At this time, the rotating shaft of the humidification filter unit 2 is arranged in the same direction as the rotating shafts of the support rollers 123 , 123 . The support rollers 123, 123 rotatably support the lower outer peripheral surface of the holding frame 23 at respective positions. Accordingly, the humidifying filter unit 2 is supported above the water tank 12 so as to be rotatable in the circumferential direction in a vertical posture.

The humidification filter unit 2 is disposed in a posture in which the humidification filter cover member 22 faces the suction port 31 side. That is, the stacking direction S of the humidifying filter 21 and the humidifying filter cover member 22 is the same as the ventilation direction of the air flowing through the air passage 3 . Moreover, the humidification filter cover member 22 is arranged so as to be positioned on the windward side of the humidification filter 21 . The humidifying filter cover member 22 collects dust and the like contained in the air that has passed through the air purifier 11 .

The rotation drive mechanism 16 has a drive motor 161 and a drive roller 162 . The drive motor 161 is fixed inside the housing 6 . The drive roller 162 is fixed to the output shaft of the drive motor 161 and rotated by the drive of the drive motor 161 . The driving roller 162 rotatably supports the upper peripheral surface of the holding frame 23 . Therefore, the humidifying filter unit 2 is supported at three points at respective positions of the support rollers 123 and 123 and the drive roller 162, that is, at different positions in the circumferential direction. In the illustrated example, the support rollers 123 and 123 and the drive roller 162 are gear rollers, and have a structure that meshes with a sprocket 234 provided on the outer peripheral surface of the holding frame 23 .

Rotation of the driving roller 162 is transmitted to the holding frame 23, and the humidifying filter unit 2 rotates around its own center O2. FIG. 7 shows a case where the humidifying filter unit 2 rotates in the direction of the arrow R. As shown in FIG.

Water at the water level L is stored in the first tray 121 . Therefore, some of the members constituting the humidifying filter unit 2 are always immersed in the water stored in the water tank 12 . As shown in FIG. 7, water does not enter the humidifying filter unit 2 when the waterproof portion 233 of the holding frame 23 and the waterproof portion 243 of the holding frame cover 24 are flooded. This state is called a "non-flooded state".

On the other hand, when the humidifying filter unit 2 in the state shown in FIG. 7 rotates in the direction of the arrow R, the through hole 231 and the reinforcing portion 232 of the holding frame 23 and the through hole 241 and the reinforcing portion 242 of the holding frame cover 24 are flooded. . In this case, water enters inside the humidifying filter unit 2 through the through holes 231 and 241 . This state is called a "flooded state".

When the humidifying filter unit 2 is in a submerged state, the lower portion of the humidifying filter 21 is positioned below the water surface of the water tank 12 . Therefore, the lower portion of the humidifying filter 21 is immersed in the water stored in the water tank 12 . On the other hand, when the humidifying filter unit 2 is not submerged, the waterproof portions 233 and 243 prevent water from entering the humidifying filter unit 2 and the humidifying filter 21 is above the water surface. Therefore, the humidifying filter 21 is not immersed in the water stored in the water tank 12 .

On the other hand, the humidifying filter cover member 22 is not immersed in the water stored in the water tank 12 regardless of whether the humidifying filter unit 2 is in the submerged state or in the non-submerged state. This is because the humidifying filter cover member 22 is always positioned above the water surface. As the humidifying filter unit 2 rotates, the submerged state and the non-submerged state are alternately switched.

When the humidifying filter unit 2 is switched to the submerged state, the water stored in the water tank 12 is absorbed by the peripheral portion of the humidifying filter 21, and then sucked up from the peripheral portion toward the center in the radial direction. Since the humidifying filter unit 2 rotates continuously, the periphery of the humidifying filter 21 is continuously soaked and absorbed in the circumferential direction, and the absorbed water is lifted by the rotational movement of the humidifying filter unit 2. When the humidifying filter unit 2 is switched to the non-submerged state, even if the humidifying filter unit 2 rotates, the humidifying filter 21 will not be submerged or absorbed. However, during one rotation of the humidifying filter unit 2, the period during which the humidifying filter unit 2 is in the submerged state is sufficiently longer than the period during which the humidifying filter unit 2 is in the non-submerged state. For this reason, if the humidification filter unit 2 continues rotating, water will efficiently spread over the entire humidification filter 21 .

When the radial center portion of the humidifying filter 21 is supplied with water, the humidifying filter cover member 22 absorbs water from the humidifying filter 21 through the portion in close contact with the humidifying filter 21 . The humidifying filter 21 that has absorbed water by the humidifying filter cover member 22 newly absorbs water from the water tank 12 accordingly. As described above, the humidifying filter 21 directly absorbs water from the water tank 12 , but the humidifying filter cover member 22 indirectly absorbs water from the water tank 12 via the humidifying filter 21 .

When the humidifying filter unit 2 is rotating, the air passing through the humidifying filter unit 2 absorbs moisture sufficiently. On the other hand, when the humidifying filter unit 2 is not rotating and the humidifying filter unit 2 is in the non-submerged state, the air passing through the humidifying filter unit 2 hardly absorbs moisture. Therefore, when both air cleaning and air humidification are performed, the rotation drive mechanism 16 operates to rotate the humidification filter unit 2 . When only air cleaning is performed and air humidification is not performed, the rotation drive mechanism 16 does not operate, and the humidifying filter unit 2 stops at the non-submerged position.

When both air cleaning and air humidification are performed, the blower 13 operates and the rotation drive mechanism 16 operates. Air is sucked into the filter housing portion 301 from the outside of the housing 6 through the suction port 31 . The sucked air flows forward through the filter housing portion 301 . At this time, the sucked air is purified and humidified by passing through the air purifier 11 and the humidifying filter unit 2 in this order to become purified humidified air. Purified and humidified air flows from the filter housing portion 301 to the blowout passage 302 . In the blowout passage 302 , the purified and humidified air flows rearward and upward, and finally blows out of the housing 6 through the blowout port 32 .

When only air cleaning is performed and air humidification is not performed, the blower 13 operates but the rotation drive mechanism 16 does not operate. Also, the humidifying filter unit 2 remains stopped at the non-flooded position. Therefore, the air sucked into the filter housing portion 301 through the suction port 31 is purified by passing through the air purification portion 11 but is not humidified by the humidifying filter unit 2 .

If the humidifying filter cover member 22 is only sandwiched between the humidifying filter 21 and the holding frame cover 24, the humidifying filter unit 2 may be placed in a vertical position or rotated. There is a possibility that the position of the cover member 22 may be displaced. When the center O22 of the humidification filter cover member 22 deviates from the center O21 of the humidification filter 21, the humidification filter cover member 22 is submerged in the water stored in the water tank 12 and absorbs the water. It becomes difficult to absorb water. In contrast, in the first embodiment, the bent positioning portion 222 is held between the positioning ribs 235 and 235 and the holding ribs 244 and 244 . Also, the slits 223, 223 and the engaging ribs 236, 236 are engaged. Therefore, even when the humidifying filter unit 2 is arranged in a vertical posture and when the humidifying filter unit 2 rotates, the positional deviation of the humidifying filter cover member 22 from the humidifying filter 21 is prevented.

As described above with reference to FIGS. 1 to 7, the humidifying filter cover member 22 according to the first embodiment covers at least a portion of the humidifying filter 21, and includes the holding frame 23 and the holding frame cover which are holding members. 24 is sandwiched together with the humidifying filter 21 for use. The humidifying filter cover member 22 includes a body portion 221 and a positioning portion 222 . The body portion 221 has air permeability and water absorption. The positioning part 222 has a shape extending in the same plane from at least a part of the edge of the main body part 221, and positions the main body part 221 with respect to the positioning ribs 235, 235 formed inside the holding member. . With this configuration, the humidification filter 21 and the humidification filter cover member 22 can be positioned with respect to the positioning ribs 235, 235, and as a result, the humidification filter 21 and the humidification filter cover member 22 are positioned. . Therefore, it is possible to easily position the humidifying filter cover member 22 with respect to the humidifying filter 21 .

In the illustrated example, the positioning ribs 235, 235 are partially replaced with the engaging ribs 236, 236, and the engaging ribs 236, 236 are engaged with the slits 223, 223 of the humidifying filter cover member 22. It is not limited to this. For example, in the stacking direction S, slits 223, 223 may be provided in portions of the positioning portion 222 overlapping the positioning ribs 235, 235, and the slits 223, 223 and the positioning ribs 235, 235 may be engaged. By engaging the positioning ribs 235 , 235 or the engaging ribs 236 , 236 with the slits 223 , 223 , the humidifying filter cover member 22 can be easily positioned with respect to the humidifying filter 21 .
