The two water supply units 21 and 21 are provided side by side in the front-rear direction (second direction) intersecting the left-right direction. Further, the water receiving portion 12 is surrounded by a wall portion 121 around the front-rear direction and the left-right direction including the two water supply portions 21 and 21. In the water receiving section 12, the water pumped up through the extension pipe 16 can be temporarily stored and passed through the two water supply sections 21 and 21 respectively.
　図３および図５に示すように、給水部２１は、断面視略Ｖ字形状の流路Ｃを有している。具体的には、給水部２１は、左右方向に延伸した底部２２と、底部２２に対して左右方向と交差する前後方向の一方側（本実施形態では後方側）に形成された略矩形状の第１傾斜面２３と、底部２２に対して前後方向の他方側（本実施形態では前方側）に形成された略矩形状の第２傾斜面２４と、を有している。 As shown in FIGS. 3 and 5, the water supply unit 21 has a flow path C having a substantially V-shaped cross section. Specifically, the water supply portion 21 has a substantially rectangular shape formed on one side (rear side in the present embodiment) of the bottom portion 22 extending in the left-right direction and the front-rear direction intersecting the bottom portion 22 in the left-right direction. It has a first inclined surface 23 and a substantially rectangular second inclined surface 24 formed on the other side (front side in the present embodiment) in the front-rear direction with respect to the bottom portion 22.
　図４に示すように、底部２２は、左右方向の給水孔１２ａに近い一方から給水孔１２ａから離れた他方に向かって下がるテーパー面をなすように形成される。具体的には、底部２２は、給水孔１２ａから離れるほど低くなるように構成されている。水受け部１２では、ポンプ１７により汲み上げた水をテーパー面に沿って、左右方向の一方から他方に向かう流れを生起させる。なお、底部２２は、テーパー面に限定するものではなく、高低差が形成されるなら、左右方向の一方から他方に向かって下がるような階段状に形成されてもよい。 As shown in FIG. 4, the bottom portion 22 is formed so as to form a tapered surface that descends from one side close to the water supply hole 12a in the left-right direction toward the other side away from the water supply hole 12a. Specifically, the bottom portion 22 is configured to be lowered as the distance from the water supply hole 12a increases. In the water receiving portion 12, the water pumped by the pump 17 causes a flow from one side in the left-right direction toward the other along the tapered surface. The bottom portion 22 is not limited to the tapered surface, and may be formed in a stepped shape so as to descend from one side in the left-right direction toward the other side, if a height difference is formed.
　図５および図６に示すように、第１傾斜面２３及び第２傾斜面２４は、底部２２から前後方向に離れるにつれて上方に傾斜している。具体的には、第１傾斜面２３及び第２傾斜面２４は、前後方向及び左右方向に沿った仮想平面に対する角度が約４５度となる傾きを有している。 As shown in FIGS. 5 and 6, the first inclined surface 23 and the second inclined surface 24 are inclined upward as they move away from the bottom 22 in the front-rear direction. Specifically, the first inclined surface 23 and the second inclined surface 24 have an inclination such that the angle with respect to the virtual plane along the front-rear direction and the left-right direction is about 45 degrees.
　図３に示すように、複数の開口２５は、第１傾斜面２３及び第２傾斜面２４のそれぞれに形成されている。各開口２５は、平面視において略円形状に形成されており、第１傾斜面２３又は第２傾斜面２４を上下方向に貫通するように形成されている。また、第１傾斜面２３及び第２傾斜面２４には、下方に延びる複数の略筒状の接続部２８，・・，２８が設けられる。接続部２８の一端は、開口２５に連通し、接続部２８の他端は、加湿用フィルタ体１１を保持する保持空間Ｓに連通している。なお、開口２５の形状は、楕円形状、四角形状やその他の多角形状であってもよい。 As shown in FIG. 3, a plurality of openings 25 are formed in each of the first inclined surface 23 and the second inclined surface 24. Each opening 25 is formed in a substantially circular shape in a plan view, and is formed so as to penetrate the first inclined surface 23 or the second inclined surface 24 in the vertical direction. Further, the first inclined surface 23 and the second inclined surface 24 are provided with a plurality of substantially cylindrical connecting portions 28, ..., 28 extending downward. One end of the connecting portion 28 communicates with the opening 25, and the other end of the connecting portion 28 communicates with the holding space S for holding the humidifying filter body 11. The shape of the opening 25 may be an elliptical shape, a quadrangular shape, or another polygonal shape.
　ここで、給水部２１の単位面積当たりにおける複数の開口２５の一部が占める割合を、開口割合とする。「複数の開口２５の一部」とは、１又は２以上の開口２５だけでなく、１つの開口２５の一部も含む。つまり、開口割合は、給水部２１の単位面積あたりにおける開口面積の総和の割合である。本開示における給水部２１の単位面積には、少なくとも１つの開口２５が含まれているとする。例えば、給水部２１の単位面積の大きさは、第１傾斜面２３及び第２傾斜面２４それぞれを、左右方向に複数分割した面積である。本実施形態では、給水部２１における、右側の開口割合は、左側の開口割合よりも大きい。つまり、給水部２１は、給水孔１２ａから遠い右側における単位面積当たりの開口面積の総和が、給水孔１２ａに近い左側における単位面積当たりの開口面積の総和よりも大きい。 Here, the ratio occupied by a part of the plurality of openings 25 per unit area of the water supply unit 21 is defined as the opening ratio. The "part of a plurality of openings 25" includes not only one or more openings 25 but also a part of one opening 25. That is, the opening ratio is the ratio of the total opening area per unit area of the water supply unit 21. It is assumed that the unit area of the water supply unit 21 in the present disclosure includes at least one opening 25. For example, the size of the unit area of the water supply unit 21 is an area obtained by dividing each of the first inclined surface 23 and the second inclined surface 24 in the left-right direction. In the present embodiment, the opening ratio on the right side of the water supply unit 21 is larger than the opening ratio on the left side. That is, in the water supply unit 21, the total opening area per unit area on the right side far from the water supply hole 12a is larger than the total opening area per unit area on the left side near the water supply hole 12a.
　具体的には、複数の開口２５，・・，２５は、開口領域の大きさが異なっている。複数の開口２５，・・，２５は、左右方向の給水孔１２ａに近い一方から給水孔１２ａから離れた他方へ向かって、開口領域（開口面積）が大きくなる。すなわち、複数の開口２５のうち、給水孔１２ａから遠い開口２５は、給水孔１２ａに近い開口２５に比べて開口領域が大きい。具体的には、第１傾斜面２３および第２傾斜面２４のそれぞれにおいて、複数の開口２５は、給水孔１２ａから離れるほど開口領域が徐々に大きくなる。また、左右方向において隣り合う開口２５，２５同士の間隔は、開口２５の開口領域が小さいほど広くなり、開口２５の開口領域が大きいほど狭くなる。 Specifically, the size of the opening area is different between the plurality of openings 25, ..., 25. The opening area (opening area) of the plurality of openings 25, ..., 25 increases from one side near the water supply hole 12a in the left-right direction toward the other side away from the water supply hole 12a. That is, of the plurality of openings 25, the opening 25 far from the water supply hole 12a has a larger opening region than the opening 25 near the water supply hole 12a. Specifically, in each of the first inclined surface 23 and the second inclined surface 24, the opening regions of the plurality of openings 25 gradually increase as the distance from the water supply hole 12a increases. Further, the distance between the openings 25 and 25 adjacent to each other in the left-right direction becomes wider as the opening area of the opening 25 becomes smaller, and becomes narrower as the opening area of the opening 25 becomes larger.
　このように、本実施形態では、第１傾斜面２３及び第２傾斜面２４それぞれに形成された複数の開口２５，・・，２５において、給水孔１２ａに近いほど開口領域が小さく、給水孔１２ａから遠いほど開口領域が大きい。したがって、給水孔１２ａから導入された水が、給水孔１２ａに近い開口の上方を通過して給水孔１２ａから遠い開口２５まで届きやすくなり、かつ、給水孔１２ａから遠い開口２５に水が流れ込みやすくなる。これにより、各開口２５に流れ込む単位時間あたりの水量の均一化を図ることができる。したがって、加湿用フィルタ体１１における左右方向に沿った各部位に対して、供給する水の量の均一化を図ることができる。 As described above, in the present embodiment, in the plurality of openings 25, ..., 25 formed on the first inclined surface 23 and the second inclined surface 24, the closer to the water supply hole 12a, the smaller the opening region, and the water supply hole 12a. The farther from, the larger the opening area. Therefore, the water introduced from the water supply hole 12a easily passes above the opening near the water supply hole 12a and reaches the opening 25 far from the water supply hole 12a, and the water easily flows into the opening 25 far from the water supply hole 12a. Become. As a result, it is possible to make the amount of water flowing into each opening 25 uniform per unit time. Therefore, it is possible to make the amount of water supplied uniform for each portion of the humidifying filter body 11 along the left-right direction.
　ここで、複数の開口２５，・・，２５を区別する場合、第１傾斜面２３に形成された複数の開口２５を複数の第１開口２５１、第２傾斜面２４に形成された複数の開口２５を複数の第２開口２５２という。つまり、複数の開口２５，・・，２５は、第１傾斜面２３に形成された複数の第１開口２５１と、第２傾斜面２４に形成された複数の第２開口２５２と、を含む。 Here, when distinguishing the plurality of openings 25, ..., 25, the plurality of openings 25 formed on the first inclined surface 23 are combined with the plurality of openings formed on the plurality of first openings 251 and the second inclined surface 24. 25 is referred to as a plurality of second openings 252. That is, the plurality of openings 25, ..., 25 includes a plurality of first openings 251 formed on the first inclined surface 23 and a plurality of second openings 252 formed on the second inclined surface 24.
　複数の第１開口２５１及び複数の第２開口２５２は、左右方向において、複数の第１開口２５１の各々と、複数の第２開口２５２の各々と、が交互に位置するように形成されている。具体的には、図３に示すように、左右方向において、複数の第１開口２５１の各々の位置と、複数の第２開口２５２の各々の位置とが、互いに異なる。言い換えれば、複数の第１開口２５１の各々と、複数の第２開口２５２の各々とは、前後方向に並ばないように左右方向にずれている。各第１開口２５１の中心と各第２開口２５２の中心とが左右方向における異なる位置となる。 The plurality of first openings 251 and the plurality of second openings 252 are formed so that each of the plurality of first openings 251 and each of the plurality of second openings 252 are alternately positioned in the left-right direction. .. Specifically, as shown in FIG. 3, the positions of the plurality of first openings 251 and the positions of the plurality of second openings 252 are different from each other in the left-right direction. In other words, each of the plurality of first openings 251 and each of the plurality of second openings 252 are displaced in the left-right direction so as not to be lined up in the front-rear direction. The center of each first opening 251 and the center of each second opening 252 are at different positions in the left-right direction.
　これにより、左右方向において、第１開口２５１と第２開口２５２とが交互に位置するので、加湿用フィルタ体１１における左右方向に沿った各部位に対して、供給する水の量の均一化を図ることができる。また、複数の第１開口２５１の各々と、複数の第２開口２５２の各々とが、前後方向に並ぶ構成に比べて、給水孔１２ａに近い第１開口２５１及び第２開口２５２の上方を水が通過しやすくなり、給水孔１２ａから遠い第１開口２５１及び第２開口２５２まで水が届きやすくなる。 As a result, the first opening 251 and the second opening 252 are alternately positioned in the left-right direction, so that the amount of water supplied to each portion of the humidifying filter body 11 along the left-right direction can be made uniform. Can be planned. Further, compared to the configuration in which each of the plurality of first openings 251 and each of the plurality of second openings 252 are arranged in the front-rear direction, water is above the first opening 251 and the second opening 252 closer to the water supply hole 12a. Is easy to pass through, and water can easily reach the first opening 251 and the second opening 252 far from the water supply hole 12a.
　さらに、図３および図４に示すように、複数の開口２５，・・，２５のうち、一部の開口２５は、底部２２よりも上方に形成される。さらに、複数の開口２５，・・，２５のうち、残りの開口２５は、一部の開口２５よりも開口領域が大きく、底部２２と連続するように形成されている。ここで、複数の開口２５を区別する場合、底部２２よりも上方に形成された一部の開口２５を小開口２５Ｓ、小開口２５Ｓよりも開口領域が大きく、底部２２と連続するように形成された残りの開口２５を大開口２５Ｌという。複数の開口２５は、複数の小開口２５Ｓ、及び複数の大開口２５Ｌを含む。第１傾斜面２３及び第２傾斜面２４それぞれに、複数の小開口２５Ｓ、及び複数の大開口２５Ｌが形成されている。左右方向において、複数の小開口２５Ｓは、複数の大開口２５Ｌよりも給水孔１２ａの近くに形成されている。 Further, as shown in FIGS. 3 and 4, among the plurality of openings 25, ..., 25, some of the openings 25 are formed above the bottom 22. Further, of the plurality of openings 25, ..., 25, the remaining openings 25 have a larger opening region than some of the openings 25 and are formed so as to be continuous with the bottom 22. Here, when distinguishing a plurality of openings 25, some of the openings 25 formed above the bottom 22 are formed so as to have a larger opening region than the small openings 25S and the small openings 25S and to be continuous with the bottom 22. The remaining opening 25 is called a large opening 25L. The plurality of openings 25 include a plurality of small openings 25S and a plurality of large openings 25L. A plurality of small openings 25S and a plurality of large openings 25L are formed on each of the first inclined surface 23 and the second inclined surface 24. In the left-right direction, the plurality of small openings 25S are formed closer to the water supply hole 12a than the plurality of large openings 25L.
　図５に示すように、小開口２５Ｓは、底部２２よりも上方に形成されている。ここでいう底部２２とは、第１傾斜面２３と第２傾斜面２４との下端同士を接続する部位である。小開口２５Ｓの開口端は、底部２２よりも上方に位置している。 As shown in FIG. 5, the small opening 25S is formed above the bottom portion 22. The bottom portion 22 referred to here is a portion that connects the lower ends of the first inclined surface 23 and the second inclined surface 24. The opening end of the small opening 25S is located above the bottom 22.
　一方、図６に示すように、大開口２５Ｌは、底部２２と連続するように形成されている。つまり、大開口２５Ｌの開口端の一部が、底部２２に形成されている。 On the other hand, as shown in FIG. 6, the large opening 25L is formed so as to be continuous with the bottom portion 22. That is, a part of the opening end of the large opening 25L is formed on the bottom portion 22.
　これにより、給水孔１２ａから導入された水が底部２２に沿ってながれ、大開口２５Ｌまで届けやすくなり、かつ、底部２２に一部が形成された大開口２５Ｌに水が流れ込みやすくなる。また、ポンプ１７が停止した場合に、底部２２に溜まった水を、大開口２５Ｌを介して排出することができるので、底部２２に水が残留することを抑制することができる。 As a result, the water introduced from the water supply hole 12a flows along the bottom 22 and easily reaches the large opening 25L, and the water easily flows into the large opening 25L partially formed in the bottom 22. Further, when the pump 17 is stopped, the water accumulated in the bottom portion 22 can be discharged through the large opening 25L, so that it is possible to prevent the water from remaining in the bottom portion 22.
［加湿装置の動作］
　次に、加湿装置の動作を説明する。加湿装置は、加湿運転を開始する操作を行うと制御部（図示しない）が操作信号を受信して、送風機８、セラミックヒータ９及びポンプ１７を制御する。 [Operation of humidifier]
Next, the operation of the humidifier will be described. When the humidifying device performs an operation to start the humidifying operation, a control unit (not shown) receives an operation signal to control the blower 8, the ceramic heater 9, and the pump 17.
　図１に示す加湿装置１では、操作部（図示しない）を操作すると加湿運転が開始される。 In the humidifying device 1 shown in FIG. 1, the humidifying operation is started by operating the operation unit (not shown).
　図７に示すように、加湿用トレー１９内には、水タンク（図示しない）から供給される水が貯められており、加湿用トレー１９内の水がポンプ１７の駆動により延長管１６を通って水受け部１２に汲み上げられる。汲み上げられた水は、各給水部２１，２１の各流路Ｃ，Ｃを流れる。 As shown in FIG. 7, water supplied from a water tank (not shown) is stored in the humidifying tray 19, and the water in the humidifying tray 19 passes through the extension pipe 16 by the drive of the pump 17. It is pumped up to the water receiving part 12. The pumped water flows through the flow paths C and C of the water supply units 21 and 21.
　水は、各給水部２１，２１に設けられた各開口２５，２５を介して下方の保持空間Ｓに流れ落ちる。具体的には、給水孔１２ａから導入された水は、一部が開口２５を介して保持空間Ｓに流れ落ちながら、流路Ｃを流れる。これにより、保持空間Ｓに配置された加湿用フィルタ体１１は、水受け部１２から複数の開口２５を介して流れ落ちた水を吸収する。複数の開口２５を介して流れ落ちた水のうち、加湿用フィルタ体１１に吸収されなかった水は、加湿用トレー１９に流れて、水受け部１２に再び汲み上げられる。 Water flows down to the lower holding space S through the openings 25 and 25 provided in the water supply units 21 and 21. Specifically, the water introduced from the water supply hole 12a flows through the flow path C while a part of the water flows down into the holding space S through the opening 25. As a result, the humidifying filter body 11 arranged in the holding space S absorbs the water that has flowed down from the water receiving portion 12 through the plurality of openings 25. Of the water that has flowed down through the plurality of openings 25, the water that has not been absorbed by the humidifying filter body 11 flows into the humidifying tray 19 and is pumped up again by the water receiving portion 12.

The farther from the hole 12a, the larger the opening area. Therefore, the water introduced from the water supply hole 12a easily passes above the opening near the water supply hole 12a and reaches the opening 25 far from the water supply hole 12a, and the water easily flows into the opening 25 far from the water supply hole 12a. Become. As a result, it is possible to make the amount of water flowing into each opening 25 uniform per unit time. Therefore, it is possible to make the amount of water supplied uniform for each portion of the humidifying filter body 11 along the left-right direction. As a result, the amount of water absorbed by the humidifying filter body 11 increases as compared with the case where water is locally supplied to the humidifying filter body 11, so that the humidifying amount can be increased. ..
　また、左右方向において、第１開口２５１と第２開口２５２とが交互に位置するので、加湿用フィルタ体１１における左右方向に沿った各部位に対して、供給する水の量の均一化を図ることができる。また、複数の第１開口２５１の各々と、複数の第２開口２５２の各々とが、前後方向に並ぶ構成に比べて、給水孔１２ａに近い第１開口２５１及び第２開口２５２の上方を水が通過しやすくなり、給水孔１２ａから遠い第１開口２５１及び第２開口２５２まで水が届きやすくなる。 Further, since the first opening 251 and the second opening 252 are alternately positioned in the left-right direction, the amount of water supplied to each portion of the humidifying filter body 11 along the left-right direction is made uniform. be able to. Further, compared to the configuration in which each of the plurality of first openings 251 and each of the plurality of second openings 252 are arranged in the front-rear direction, water is above the first opening 251 and the second opening 252 closer to the water supply hole 12a. Is easy to pass through, and water can easily reach the first opening 251 and the second opening 252 far from the water supply hole 12a.
　また、小開口２５Ｓ（図５参照）は、底部２２よりも上方に形成され、大開口２５Ｌ（図６参照）は、底部２２と連続するように形成されている。これにより、給水孔１２ａから導入された水が底部２２に沿ってながれ、大開口２５Ｌまで届けやすくなり、かつ、底部２２に一部が形成された大開口２５Ｌに水が流れ込みやすくなる。 Further, the small opening 25S (see FIG. 5) is formed above the bottom portion 22, and the large opening 25L (see FIG. 6) is formed so as to be continuous with the bottom portion 22. As a result, the water introduced from the water supply hole 12a flows along the bottom 22 and easily reaches the large opening 25L, and the water easily flows into the large opening 25L partially formed in the bottom 22.
　このように、本実施形態の加湿フィルタ用ホルダ１０は、加湿用フィルタ体１１が配置される保持空間Ｓの上方に位置し、加湿用フィルタ体１１に供給するための水を受ける水受け部１２を備えている。また、水受け部１２は、第１方向を長手方向とし第１方向の一方から水が導入され、保持空間Ｓに連通する複数の開口２５，・・，２５が形成された給水部２１を有する。さらに、複数の開口２５，・・，２５は、開口領域が異なっており、第１方向の一方より他方で、開口領域が大きくなる。したがって、給水孔１２ａから導入された水が、給水孔１２ａに近い開口の上方を通過して給水孔１２ａから遠い開口２５まで届きやすくなり、かつ、給水孔１２ａから遠い開口２５に水が流れ込みやすくなる。これにより、各開口２５に流れ込む単位時間あたりの水量の均一化を図ることができる。したがって、加湿用フィルタ体１１における左右方向に沿った各部位に対して、供給する水の量の均一化を図ることができる。よって、加湿フィルタ用ホルダ１０によれば、より効率的に散水動作を行える効果を実現し得る。 As described above, the humidifying filter holder 10 of the present embodiment is located above the holding space S in which the humidifying filter body 11 is arranged, and is a water receiving portion 12 that receives water to be supplied to the humidifying filter body 11.

Further, the water receiving portion 12 has a water supply portion 21 in which water is introduced from one of the first directions with the first direction as the longitudinal direction and a plurality of openings 25, ..., 25 communicating with the holding space S are formed. .. Further, the plurality of openings 25, ..., 25 have different opening regions, and the opening region is larger on the other side than on one side in the first direction.

Become. As a result, it is possible to make the amount of water flowing into each opening 25 uniform per unit time. Therefore, it is possible to make the amount of water supplied uniform for each portion of the humidifying filter body 11 along the left-right direction. Therefore, according to the humidifying filter holder 10, it is possible to realize the effect that the watering operation can be performed more efficiently.

The humidifying device according to the second embodiment will be described with reference to FIGS. 8 to 10. The humidifying device of the second embodiment is different from the humidifying device of the first embodiment in the positions of the plurality of openings. The components of the second embodiment are designated by the same reference numerals as those of the first embodiment, and duplicate description will be omitted.
　図８から図１０に示すように、本実施形態の加湿フィルタ用ホルダ１０は、１つの給水部２１を有している。給水部２１は、左右方向（第１方向）を長手方向とし、左右方向における給水孔１２ａに近い一方（本実施形態では左方）から水が導入される。給水部２１は、断面視略Ｖ字形状の流路Ｃを有している。具体的には、給水部２１は、左右方向に延伸した底部２２と、底部２２に対して左右方向と交差する前後方向の一方側（本実施形態では前方側）に形成された略矩形状の第１傾斜面２３と、底部２２に対して前後方向の他方側（本実施形態では後方側）に形成された略矩形状の第２傾斜面２４と、を有している。 As shown in FIGS. 8 to 10, the humidifying filter holder 10 of the present embodiment has one water supply unit 21. The water supply unit 21 has a longitudinal direction in the left-right direction (first direction), and water is introduced from one side close to the water supply hole 12a in the left-right direction (left side in the present embodiment). The water supply unit 21 has a flow path C having a substantially V-shaped cross section. Specifically, the water supply portion 21 has a substantially rectangular shape formed on one side (front side in the present embodiment) of the bottom portion 22 extending in the left-right direction and the front-rear direction intersecting the bottom portion 22 in the left-right direction. It has a first inclined surface 23 and a substantially rectangular second inclined surface 24 formed on the other side (rear side in the present embodiment) in the front-rear direction with respect to the bottom portion 22.
　給水部２１には、保持空間Ｓに連通する複数の開口２５，・・，２５が形成されている。具体的には、複数の開口２５，・・，２５は、底部２２の前後両側において、左右方向に沿った２列に形成されている。複数の開口２５，・・，２５は、第１傾斜面２３及び第２傾斜面２４それぞれに形成されている。具体的には、底部２２の前方において、複数の開口２５，・・，２５は、第１傾斜面２３と、第１傾斜面２３の上端から前方に延びる第１平面２６とにわたって形成されている。また、底部２２の後方において、複数の開口２５，・・，２５は、第２傾斜面２４と、第２傾斜面２４の上端から後方に延びる第２平面２７とにわたって形成されている。第１平面２６及び第２平面２７は、前後方向及び左右方向に沿うように形成されている。 The water supply unit 21 is formed with a plurality of openings 25, ..., 25 communicating with the holding space S. Specifically, the plurality of openings 25, ..., 25 are formed in two rows along the left-right direction on both front and rear sides of the bottom portion 22. The plurality of openings 25, ..., 25 are formed on the first inclined surface 23 and the second inclined surface 24, respectively. Specifically, in front of the bottom portion 22, a plurality of openings 25, ..., 25 are formed over a first inclined surface 23 and a first plane 26 extending forward from the upper end of the first inclined surface 23. .. Further, behind the bottom portion 22, a plurality of openings 25, ..., 25 are formed over a second inclined surface 24 and a second plane 27 extending rearward from the upper end of the second inclined surface 24. The first plane 26 and the second plane 27 are formed along the front-rear direction and the left-right direction.
　複数の開口２５，・・，２５は、開口領域の大きさが異なっている。複数の開口２５，・・，２５は、左右方向の給水孔１２ａに近い一方から給水孔１２ａから離れた他方へ向かって、開口領域（面積）が大きくなる。すなわち、複数の開口２５のうち、給水孔１２ａから遠い開口２５は、給水孔１２ａに近い開口２５に比べて開口領域が大きい。具体的には、第１傾斜面２３及び第２傾斜面２４のそれぞれにおいて、複数の開口２５は、給水孔１２ａから離れるほど開口領域が徐々に大きくなる。 The size of the opening area is different between the plurality of openings 25, ..., 25. The opening areas (areas) of the plurality of openings 25, ..., 25 increase from one near the water supply hole 12a in the left-right direction toward the other away from the water supply hole 12a. That is, of the plurality of openings 25, the opening 25 far from the water supply hole 12a has a larger opening region than the opening 25 near the water supply hole 12a. Specifically, in each of the first inclined surface 23 and the second inclined surface 24, the opening regions of the plurality of openings 25 gradually increase as the distance from the water supply hole 12a increases.
　また、複数の開口２５，・・，２５は、底部２２より上方に形成されている。具体的には、各開口２５は、周縁部全体が底部２２よりも上方となるように形成されている。言い換えれば、各開口２５は、周縁部が第１傾斜面２３及び第２傾斜面２４に沿って底部２２から離れている。 Further, the plurality of openings 25, ..., 25 are formed above the bottom portion 22. Specifically, each opening 25 is formed so that the entire peripheral edge portion is above the bottom portion 22. In other words, each opening 25 has a peripheral edge separated from the bottom 22 along the first inclined surface 23 and the second inclined surface 24.
　また、第１傾斜面２３に形成された複数の開口２５，・・，２５の各々と、第２傾斜面２４に形成された複数の開口２５，・・，２５の各々とは、左右方向における位置が同じとなるように形成されている。言い換えれば、第１傾斜面２３に形成された複数の開口２５，・・，２５の各々と、第２傾斜面２４に形成された複数の開口２５，・・，２５の各々とは、前後方向に並ぶように形成されている。 Further, each of the plurality of openings 25, ..., 25 formed on the first inclined surface 23 and each of the plurality of openings 25, ..., 25 formed on the second inclined surface 24 are in the left-right direction. It is formed so that the positions are the same. In other words, each of the plurality of openings 25, ..., 25 formed on the first inclined surface 23 and each of the plurality of openings 25, ..., 25 formed on the second inclined surface 24 are in the front-rear direction. It is formed so as to line up with.
　このように、本実施形態の加湿フィルタ用ホルダ１０では、複数の開口２５，・・，２５が底部２２よりも上方に形成されている。したがって、給水孔１２ａから導入された水は、給水部２１を流れ、複数の開口２５から溢れ出る。また、複数の開口２５，・・，２５は、給水孔１２ａに近いほど開口領域が小さく、給水孔１２ａから遠いほど開口領域が大きい。つまり、複数の開口２５，・・，２５は、水の流れが緩い下流に向かうにつれて、開口領域が大きくなるように形成されている。これにより、各開口２５に流れ込む単位時間あたりの水量の均一化を図ることができる。したがって、加湿用フィルタ体１１における左右方向に沿った各部位に対して、供給する水の量の均一化を図ることができる。 As described above, in the humidifying filter holder 10 of the present embodiment, a plurality of openings 25, ..., 25 are formed above the bottom portion 22. Therefore, the water introduced from the water supply hole 12a flows through the water supply unit 21 and overflows from the plurality of openings 25. Further, in the plurality of openings 25, ..., 25, the closer to the water supply hole 12a, the smaller the opening area, and the farther from the water supply hole 12a, the larger the opening area. That is, the plurality of openings 25, ..., 25 are formed so that the opening region becomes larger as the water flow is slower toward the downstream. As a result, it is possible to make the amount of water flowing into each opening 25 uniform per unit time. Therefore, it is possible to make the amount of water supplied uniform for each portion of the humidifying filter body 11 along the left-right direction.
　（変形例）
　次に、加湿フィルタ用ホルダ１０の変形例について説明する。以下に説明する各変形例は、上述した実施形態、又は変形例同士の構成を適宜組み合わせて適用可能である。なお、以下の説明では、上述した実施形態と同様の構成については、同一の符号を付して説明を適宜省略する。 (Modification example)
Next, a modification of the humidifying filter holder 10 will be described. Each of the modified examples described below can be applied by appropriately combining the above-described embodiments or configurations of the modified examples. In the following description, the same components as those in the above-described embodiment are designated by the same reference numerals, and the description thereof will be omitted as appropriate.
　上述した実施形態では、給水部２１に形成された複数の開口２５は、開口領域が異なっており、給水孔１２ａから離れるにつれて開口領域が徐々に大きくなるように形成されていた。これにより、上述した実施形態では、給水部２１における、給水孔１２ａから遠い右側の開口割合が、給水孔１２ａに近い左側の開口割合よりも大きくなるように構成されていた。しかしながら、給水部２１における右側の開口割合を、左側の開口割合よりも大きくする構成は、上記構成に限らない。 In the above-described embodiment, the plurality of openings 25 formed in the water supply portion 21 have different opening regions, and the opening regions are formed so as to gradually increase as the distance from the water supply hole 12a increases. As a result, in the above-described embodiment, the opening ratio on the right side far from the water supply hole 12a in the water supply unit 21 is configured to be larger than the opening ratio on the left side near the water supply hole 12a. However, the configuration in which the opening ratio on the right side of the water supply unit 21 is larger than the opening ratio on the left side is not limited to the above configuration.
　図１１に示すように、給水部２１に形成された複数の開口２５は、開口領域の大きさが複数種類あり、右方に向かうにつれて開口領域が段階的に大きくなるように形成されていてもよい。図１１に示す例では、複数の開口２５は、開口領域の大きさが３種類あり、各種の開口２５の数は同数である。複数（１２個）の開口２５は、６個ずつ左右方向に沿った２列に形成されている。複数の開口２５は、各列において、開口領域の大きさが同一である２つの開口２５を１段として、右方に向かうにつれて開口領域の大きさが３段階で大きくなるように形成されている。これにより、給水部２１における、給水孔１２ａから遠い右側の開口割合が、給水孔１２ａに近い左側の開口割合よりも大きくなるように構成されている。 As shown in FIG. 11, the plurality of openings 25 formed in the water supply unit 21 have a plurality of sizes of opening regions, and even if the opening regions are formed so as to gradually increase toward the right. good. In the example shown in FIG. 11, the plurality of openings 25 have three different sizes of opening regions, and the number of various openings 25 is the same. The plurality of (12) openings 25 are formed in two rows along the left-right direction, six each. The plurality of openings 25 are formed so that the size of the opening region increases in three stages toward the right, with two openings 25 having the same size of the opening region as one stage in each row. .. As a result, the opening ratio on the right side far from the water supply hole 12a in the water supply unit 21 is configured to be larger than the opening ratio on the left side near the water supply hole 12a.
　また、図１２に示すように、給水部２１に形成された複数の開口２５は、開口領域の大きさが互いに同じであり、右方に向かうにつれて開口２５の間隔が小さくなるように形成されていてもよい。図１２に示す例では、複数の開口２５は、左右方向に沿った２列に形成されている。複数の開口２５は、各列において、左右方向に隣接する２つの開口２５の間隔が右方に向かうにつれて狭くなるように形成されている。したがって、右方に向かうにつれて、給水部２１の単位面積あたりにおける開口２５の数が増える。これにより、給水部２１における、給水孔１２ａから遠い右側の開口割合が、給水孔１２ａに近い左側の開口割合よりも大きくなるように構成されている。 Further, as shown in FIG. 12, the plurality of openings 25 formed in the water supply unit 21 are formed so that the sizes of the opening regions are the same as each other and the distance between the openings 25 becomes smaller toward the right. You may. In the example shown in FIG. 12, the plurality of openings 25 are formed in two rows along the left-right direction. The plurality of openings 25 are formed so that the distance between the two openings 25 adjacent to each other in the left-right direction becomes narrower toward the right in each row. Therefore, the number of openings 25 per unit area of the water supply unit 21 increases toward the right. As a result, the opening ratio on the right side far from the water supply hole 12a in the water supply unit 21 is configured to be larger than the opening ratio on the left side near the water supply hole 12a.
　なお、図１２に示す例では、複数の開口２５は、開口領域の大きさが互いに同じに形成されているが、開口領域の大きさが異なっていてもよい。例えば、複数の開口２５は、右方に向かうにつれて、開口２５の間隔が小さくなり、かつ、開口領域が徐々に大きくなるように形成されていてもよい。 In the example shown in FIG. 12, the plurality of openings 25 are formed to have the same size of the opening regions, but the sizes of the opening regions may be different. For example, the plurality of openings 25 may be formed so that the distance between the openings 25 becomes smaller and the opening area gradually increases toward the right.
　また、各開口２５は、内周面に水の表面張力を低減させる低減機構が形成されていてもよい。低減機構は、例えば、リブ、溝、凹部、凸部等である。開口２５の内周面に低減機構が形成されていることによって、開口２５の内側又は周縁部において水が表面張力によって留まることが抑制される。これにより、水が開口２５を不通となることが抑制され、加湿用フィルタ体１１への給水量の向上を図ることができる。また、開口２５の形状は、真円形状に限らず、楕円形状であってもよいし、四角形状、六角形状などの多角形状であってもよい。 Further, each opening 25 may be formed with a reduction mechanism for reducing the surface tension of water on the inner peripheral surface. The reduction mechanism is, for example, a rib, a groove, a concave portion, a convex portion, or the like. By forming the reduction mechanism on the inner peripheral surface of the opening 25, it is possible to prevent water from staying due to surface tension inside or at the peripheral edge of the opening 25. As a result, it is possible to prevent water from blocking the opening 25, and it is possible to improve the amount of water supplied to the humidifying filter body 11. Further, the shape of the opening 25 is not limited to a perfect circular shape, but may be an elliptical shape, or may be a polygonal shape such as a quadrangular shape or a hexagonal shape.
　また、上述した本実施形態では、加湿フィルタ用ホルダ１０は、１つの給水部２１を備える構成であるが、前後方向に並ぶ複数（例えば２つ）の給水部２１を備える構成であってもよい。 Further, in the above-described embodiment, the humidifying filter holder 10 is configured to include one water supply unit 21, but may be configured to include a plurality of (for example, two) water supply units 21 arranged in the front-rear direction. ..
　本発明は、上記実施形態に限定されるものではなく、上記実施形態で示した構成と実質的に同一の構成、同一の作用効果を奏する構成又は同一の目的を達成することができる構成で置き換えてもよい。 The present invention is not limited to the above embodiment, but is replaced with a configuration that is substantially the same as the configuration shown in the above embodiment, a configuration that exhibits the same action and effect, or a configuration that can achieve the same object. You may.

It has a second inclined surface 24 formed forward with respect to the bottom portion 22.
　なお、本実施形態では、図１３，図１４に示すように、給水部２１は、第１傾斜面２３と第２傾斜面２４との一方の傾斜面にのみ複数の開口２５が形成されている。具体的には、後方の給水部２１は、第１傾斜面２３に複数の開口２５が形成され、前方の給水部２１は、第２傾斜面２４に複数の開口２５が形成されている。なお、第１の実施形態と同様に、給水部２１は、第１の傾斜面２３と第２の傾斜面２４との両方に複数の開口２５が形成されていてもよい。 In this embodiment, as shown in FIGS. 13 and 14, the water supply unit 21 has a plurality of openings 25 formed only on one inclined surface of the first inclined surface 23 and the second inclined surface 24. .. Specifically, the rear water supply unit 21 has a plurality of openings 25 formed in the first inclined surface 23, and the front water supply unit 21 has a plurality of openings 25 formed in the second inclined surface 24. As in the first embodiment, the water supply unit 21 may have a plurality of openings 25 formed in both the first inclined surface 23 and the second inclined surface 24.
　仕切板２９は、前方の給水部２１における第１傾斜面２３と、後方の給水部２１における第２傾斜面２４との接続部から、上方に突出するように形成されている。仕切板２９は、左右方向に沿った矩形板状に形成されており、前後方向を厚さ方向とする。また、仕切板２９は、給水部２１における左右方向の両端にわたって形成されている。 The partition plate 29 is formed so as to project upward from the connection portion between the first inclined surface 23 in the front water supply unit 21 and the second inclined surface 24 in the rear water supply unit 21. The partition plate 29 is formed in a rectangular plate shape along the left-right direction, and the front-rear direction is the thickness direction. Further, the partition plate 29 is formed over both ends of the water supply unit 21 in the left-right direction.
　２つの給水部２１には、それぞれ左方から水が導入される。具体的には、図１３に示すように、２つの給水部２１は、２つの給水部２１に対して左前方に設けられた給水孔１２ａから水が導入される。つまり、２つの給水部２１には、給水孔１２ａから右後方に向かって流れる水が導入される。図１３では、給水孔１２ａから供給される水の流れを矢印で概念的に示している。 Water is introduced from the left into each of the two water supply units 21.

　ここで、本実施形態の水受け部１２には、２つの給水部２１を前後方向に仕切る仕切板２９が設けられている。したがって、左前方から２つの給水部２１に向かって流れる水の一部は、仕切板２９によって遮られるため、前方の給水部２１における第１傾斜面２３を越えて後方の給水部２１に流れ込むことが抑制される。仕切板２９によって遮られた水は、仕切板２９に沿って右方向に流れ、前方の給水部２１に形成された複数の開口２５を介して、加湿用フィルタ体１１に供給される。 Here, the water receiving unit 12 of the present embodiment is provided with a partition plate 29 that partitions the two water supply units 21 in the front-rear direction. Therefore, a part of the water flowing from the left front toward the two water supply units 21 is blocked by the partition plate 29, so that the water flows into the rear water supply unit 21 beyond the first inclined surface 23 of the front water supply unit 21. Is suppressed. The water blocked by the partition plate 29 flows to the right along the partition plate 29 and is supplied to the humidifying filter body 11 through the plurality of openings 25 formed in the front water supply portion 21.
　このように、本実施形態では、仕切板２９によって、前方の給水部２１の第１傾斜面２３を越えて後方の給水部２１に水が流れ込むことを抑制することで、前方の給水部２１に導入される水量を確保することができる。これにより、前方の給水部２１と後方の給水部２１とで導入される水量の差を低減することができるので、前方の加湿用フィルタ体１１と後方の加湿用フィルタ体１１とに供給する水量の差を低減することができる。結果的に、２つの加湿用フィルタ体１１の全体を効率よく濡らすことができる。 As described above, in the present embodiment, the partition plate 29 suppresses the flow of water into the rear water supply unit 21 beyond the first inclined surface 23 of the front water supply unit 21 to the front water supply unit 21. The amount of water to be introduced can be secured. As a result, the difference in the amount of water introduced between the front water supply unit 21 and the rear water supply unit 21 can be reduced, so that the amount of water supplied to the front humidification filter body 11 and the rear humidification filter body 11 The difference between the two can be reduced. As a result, the entire two humidifying filter bodies 11 can be efficiently wetted.

In this case, for example, the partition plate 29 may be formed from the left end of the water supply unit 21 to the center of the water supply unit 21.
　また、本実施形態では、仕切板２９は、仕切板２９の上端と、水受け部１２を上方から覆うカバーとの間に僅かに隙間が形成されるように設けられているが、仕切板２９の上端がカバーに接触していてもよい。 Further, in the present embodiment, the partition plate 29 is provided so that a slight gap is formed between the upper end of the partition plate 29 and the cover that covers the water receiving portion 12 from above, but the partition plate 29 is provided. The upper end of the cover may be in contact with the cover.
　また、本実施形態では、仕切板２９は、水受け部１２から上方に突出するように形成されているが、水受け部１２を上方から覆うカバーから下方に突出するように形成されていてもよい。この場合、仕切板２９は、仕切板２９の下端が水受け部１２に接触していてもよいし、僅かに隙間が形成されていてもよい。 Further, in the present embodiment, the partition plate 29 is formed so as to protrude upward from the water receiving portion 12, but may be formed so as to protrude downward from the cover covering the water receiving portion 12 from above. good.
