According to the present invention, a humidifier is provided with: a water storage tray (4) for storing water; a sirocco fan (22) for generating an air flow; and an air-blowing passage (217) by which the air brought in from the outside by the sirocco fan (22) is guided along the periphery of the sirocco fan (22) to the water storage tray (4). The air-blowing passage (217) has an inner peripheral wall (217b) provided so as to surround the sirocco fan (22). The inner peripheral wall (217b) is highest near the water storage tray (4), and is formed in the air-blowing passage (217) to decrease in height in the opposite direction of the direction in which the air is guided.

Description

空気調和機Air conditioner
　本発明は、転倒時の漏水から電気部品を保護する構造を有する空気調和機に関する。 The present invention relates to an air conditioner having a structure for protecting electric components from water leakage when falling.
　加湿機は、蒸発させる水を貯えるためのトレイを内部に備えている。トレイは、水を蒸発させるために上方が開放されている。このため、加湿機が転倒すると、トレイから水が流れ出てしまう。流れ出た水が加湿機の内部に設けられた電気部品にかかると、電気部品を損傷させる虞がある。このような転倒時の漏水対策として、様々な改良が試みられている。 湿 The humidifier is equipped with a tray for storing water to be evaporated. The tray is open at the top to evaporate water. Therefore, when the humidifier falls over, water flows out of the tray. If the water that has flowed out hits the electric components provided inside the humidifier, the electric components may be damaged. Various improvements have been attempted as a countermeasure against water leakage at the time of such a fall.
　例えば、特許文献１には、筺体が加湿ユニットに対してヒータユニットが配置された側に転倒した際にも、加湿ユニットの水がこぼれる範囲外に結線部が位置されていることが開示されている。これにより、装置が転倒した際にも、加湿ユニットの水がヒータユニットの結線部にかかるのを未然に防止できる。 For example, Patent Literature 1 discloses that even when the housing is overturned to the side where the heater unit is disposed with respect to the humidifying unit, the connection portion is located outside the range where the water of the humidifying unit spills. I have. Thereby, even when the apparatus falls, it is possible to prevent the water of the humidifying unit from splashing on the connection portion of the heater unit.

　しかしながら、トレイに貯えられる水の量が多い加湿機、トレイと電気部品との間の距離が近い加湿機などでは、特許文献１に開示された構造を採用しても、転倒時に電気部品に水がかかることが避けられない可能性が高い。 However, in a humidifier having a large amount of water stored in the tray, a humidifier having a short distance between the tray and the electric component, etc., even when the structure disclosed in Patent Document 1 is adopted, the electric component is not covered with water when it falls down. It is highly likely that this will be inevitable.
　本発明の一態様は、空気調和機の転倒時に流れ出た水が電気部品にかかることをより確実に防止することを目的とする。 の 一 One embodiment of the present invention aims to more reliably prevent water flowing out of an air conditioner from falling on electric components.
　上記の課題を解決するために、本発明の一態様に係る空気調和機は、水を貯留する貯水トレイと、空気の流れを生成するファンと、前記ファンによって外部から取り込まれた空気を前記ファンの周囲に沿って前記貯水トレイに導く送風路と、を備え、前記送風路が、前記ファンを取り囲むように設けられた壁体を有し、前記壁体が、前記貯水トレイに最も近い側が最も高く、かつ前記送風路において空気が導かれる方向の逆方向に沿って低くなるように形成されている。 In order to solve the above problems, an air conditioner according to one embodiment of the present invention has a water storage tray that stores water, a fan that generates an air flow, and an air taken in from outside by the fan. And an air passage leading to the water storage tray along the periphery of the water storage tray, wherein the air flow path has a wall provided so as to surround the fan, and the wall is closest to the water storage tray on the side closest to the water storage tray. It is formed so as to be high and low along the direction opposite to the direction in which air is guided in the air passage.
　本発明の一態様によれば、空気調和機の転倒時に流れ出た水が電気部品にかかることをより確実に防止することできる。 According to one embodiment of the present invention, it is possible to more reliably prevent the water flowing out when the air conditioner falls over from hitting the electric components.

　図１～図３に示すように、加湿機１００（空気調和機）は、筐体１と、電気稼働部２と、上部カバー３と、貯水トレイ４とを備えている。なお、以降の説明において、図２に示す筐体１の右側を右部と称し、筐体１の左側を左部と称する。 As shown in FIGS. 1 to 3, the humidifier 100 (air conditioner) includes a housing 1, an electric operation unit 2, an upper cover 3, and a water storage tray 4. In the following description, the right side of the housing 1 shown in FIG. 2 is referred to as a right portion, and the left side of the housing 1 is referred to as a left portion.
　筐体１において、電気稼働部２は上側に配置され、貯水トレイ４は下側に配置されている。筐体１は、電気稼働部２および貯水トレイ４の側部を覆うように形成されている。また、図２に示すように、筐体１における一方の上部側面には、外部の空気を取り入れる吸気口１１が設けられている。図４に示すように、吸気口１１は、グリル１２によって通気可能となるように覆われている。 In the housing 1, the electric operation unit 2 is disposed on the upper side, and the water storage tray 4 is disposed on the lower side. The housing 1 is formed so as to cover the side of the electric operating unit 2 and the water storage tray 4. Further, as shown in FIG. 2, an intake port 11 for taking in external air is provided on one upper side surface of the housing 1. As shown in FIG. 4, the intake port 11 is covered by a grill 12 so as to allow ventilation.
　電気稼働部２は、電気によって稼働する部分であり、保持フレーム２１、シロッコファン２２（図３）、モータ２３（図４および図５）、ヒータ２４（図４および図５）などを有している。 The electric operating section 2 is a section that is operated by electricity, and includes a holding frame 21, a sirocco fan 22 (FIG. 3), a motor 23 (FIGS. 4 and 5), a heater 24 (FIGS. 4 and 5), and the like. I have.
　保持フレーム２１は、シロッコファン２２（ファン）だけでなく、電気部品であるモータ２３、ヒータ２４など保持するフレームである。 The holding frame 21 is a frame for holding not only the sirocco fan 22 (fan) but also the electric components such as the motor 23 and the heater 24.
　保持フレーム２１の上端部において、左部側には、加湿された空気を吹き出す吹出口２１１が設けられ、右部側には、貯水トレイ４に供給する水を流し込む給水口２１２が設けられている。また、保持フレーム２１の右部側には、給水溝２１３が設けられている。給水溝２１３は、給水口２１２から貯水トレイ４の右部側の上端に至る範囲に上下方向に形成されている。このように構成される給水溝２１３は、筐体１における右部側の内壁とで管状の給水路を形成することによって、給水口２１２から貯水トレイ４に水を導く。 At the upper end of the holding frame 21, an outlet 211 for blowing out humidified air is provided on the left side, and a water supply port 212 for flowing water supplied to the water storage tray 4 is provided on the right side. . A water supply groove 213 is provided on the right side of the holding frame 21. The water supply groove 213 is formed vertically in a range from the water supply port 212 to the upper end on the right side of the water storage tray 4. The water supply groove 213 configured as described above forms a tubular water supply path with the inner wall on the right side of the housing 1, thereby guiding water from the water supply port 212 to the water storage tray 4.
　図３に示すように、保持フレーム２１の底部において、右部側には、シロッコファン２２によって送られた空気を貯水トレイ４へ放出する通気口２１４（空気排出口）が設けられている。通気口２１４は、方形に形成されており、グリル２１５によって通気可能となるように覆われている。 通 気 As shown in FIG. 3, a vent 214 (air outlet) for discharging the air sent by the sirocco fan 22 to the water storage tray 4 is provided on the right side at the bottom of the holding frame 21. The ventilation hole 214 is formed in a square shape, and is covered by the grill 215 so as to allow ventilation.
　保持フレーム２１における上端部と下端部との間には、モータ保持部２１６と、送風路２１７とが設けられている。 モ ー タ A motor holding portion 216 and an air passage 217 are provided between the upper end and the lower end of the holding frame 21.
　モータ保持部２１６は、シロッコファン２２を回転駆動するモータ２３を固定するために設けられている。モータ保持部２１６には、ヒータ２４も保持されている。 The motor holding section 216 is provided for fixing the motor 23 that drives the sirocco fan 22 to rotate. The motor holding unit 216 also holds the heater 24.
　シロッコファン２２は、貯水トレイ４の上方で筐体１内において空気の流れを生成するために設けられている。ヒータ２４は、シロッコファン２２の後背部側における吸気口１１の付近に配置されている。このヒータ２４は、吸気口１１を通じて外部から取り込まれた空気を加熱するために設けられている。 The sirocco fan 22 is provided above the water storage tray 4 to generate a flow of air in the housing 1. The heater 24 is arranged near the intake port 11 on the rear side of the sirocco fan 22. The heater 24 is provided to heat air taken in from the outside through the air inlet 11.
　送風路２１７は、吸気口１１から取り込まれた空気をシロッコファン２２の周囲に沿って貯水トレイ４に導く通路である。送風路２１７は、外周壁２１７ａ、内周壁２１７ｂ（壁体）および側壁２１７ｃを有している。送風路２１７のさらに詳細な構成については、後述する実施形態１において詳しく説明する。 風 The air passage 217 is a passage that guides the air taken in from the intake port 11 to the water storage tray 4 along the periphery of the sirocco fan 22. The air passage 217 has an outer peripheral wall 217a, an inner peripheral wall 217b (wall), and a side wall 217c. A more detailed configuration of the air passage 217 will be described in detail in a first embodiment described later.
　図１に示すように、上部カバー３は、筐体１の上端の開口部に配置されている。上部カバー３は、ディフューザ３１と、案内板３２と、操作・表示パネル３３とを有している。 上部 As shown in FIG. 1, the upper cover 3 is disposed in an opening at the upper end of the housing 1. The upper cover 3 has a diffuser 31, a guide plate 32, and an operation / display panel 33.
　ディフューザ３１は、保持フレーム２１の吹出口２１１から吹き出された空気を拡散させるために設けられている。ディフューザ３１は、上部カバー３に着脱可能に設けられている。 The diffuser 31 is provided for diffusing the air blown out from the outlet 211 of the holding frame 21. The diffuser 31 is detachably provided on the upper cover 3.
　案内板３２は、上方から注ぎ込まれる水を保持フレーム２１の給水口２１２に案内するために設けられている。このため、案内板３２は、給水口２１２の側に下り傾斜となるように形成されている。 The guide plate 32 is provided for guiding water poured from above to the water supply port 212 of the holding frame 21. For this reason, the guide plate 32 is formed so as to be inclined downward toward the water supply port 212.
　操作・表示パネル３３は、ユーザが操作を行うための各種の操作ボタン（運転ボタンなど）と、加湿機１００の動作状態（運転ＯＮ・ＯＦＦ、タイマー動作など）を表示するランプとを含んでいる。 The operation / display panel 33 includes various operation buttons (operation buttons and the like) for the user to operate, and a lamp for displaying the operation state (operation ON / OFF, timer operation, and the like) of the humidifier 100. .
　貯水トレイ４は、上述の給水路を介して供給された水を貯留するためのトレイであり、加湿に用いるすべての水を貯留するように大容量に構成されている。貯水トレイ４には、貯えた水を気化するための気化フィルタ５（図３）が配置されている。また、貯水トレイ４は、筐体１に着脱可能に設けられており、引き出し形式で筐体１に装着される。貯水トレイ４には、貯水トレイ４を持ち運びするための把手４３が設けられている。把手４３は、貯水トレイ４の両側壁に回動可能に取り付けられている。 The water storage tray 4 is a tray for storing the water supplied through the above-described water supply channel, and has a large capacity to store all the water used for humidification. A vaporizing filter 5 (FIG. 3) for vaporizing the stored water is disposed on the water storage tray 4. The water storage tray 4 is detachably provided on the housing 1 and is attached to the housing 1 in a drawer format. The water storage tray 4 is provided with a handle 43 for carrying the water storage tray 4. The handles 43 are rotatably attached to both side walls of the water storage tray 4.
　上記のように構成される加湿機１００においては、図３にて矢印で示す方向に回転するシロッコファン２２によって送風力が発生する。この送風力によって、筐体１の吸気口１１から取り込まれた空気が、ヒータ２４によって加熱された後、送風路２１７および通気口２１４を通じて貯水トレイ４に導かれる。貯水トレイ４においては、気化フィルタ５が、貯えられた水を全体に吸い上げている。貯水トレイ４に導かれた空気は、気化フィルタ５を通過することにより、水分を含んだ状態で放出される。気化フィルタ５に吹き込まれる空気が暖められているため、気化フィルタ５による気化効率を高めることができる。 に お い て In the humidifier 100 configured as described above, wind power is generated by the sirocco fan 22 rotating in the direction indicated by the arrow in FIG. The air blown from the air inlet 11 of the housing 1 by the blower air is heated by the heater 24, and then guided to the water storage tray 4 through the air blow path 217 and the vent 214. In the water storage tray 4, the vaporization filter 5 sucks up the stored water as a whole. The air guided to the water storage tray 4 is discharged in a state containing moisture by passing through the vaporization filter 5. Since the air blown into the vaporization filter 5 is warmed, the vaporization efficiency of the vaporization filter 5 can be increased.
　気化フィルタ５を通過した水分を含む空気は、シロッコファン２２の背後側の通路（図示せず）を通り抜けて吹出口２１１に送り出され、ディフューザ３１を介して外部に放出される。 (4) The air containing moisture that has passed through the vaporization filter 5 passes through a passage (not shown) behind the sirocco fan 22, is sent out to the outlet 211, and is discharged to the outside through the diffuser 31.
　なお、加湿機１００におけるファンは、シロッコファン２２には限定されない。ファンとしては、ターボファン、クロスフローファン、軸流ファン、斜流ファンなどを用いてもよい。 The fan in the humidifier 100 is not limited to the sirocco fan 22. As the fan, a turbo fan, a cross flow fan, an axial flow fan, a mixed flow fan, or the like may be used.
　また、加湿機１００は給水タンクを用いないタンクレス式である。しかしながら、加湿機１００は、給水タンクを備えて、給水タンクから貯水トレイ４に水を供給するタンク式であってもよい。給水タンクを備える加湿機１００において、貯水トレイ４の容量は小さくてよい。 The humidifier 100 is a tankless type that does not use a water supply tank. However, the humidifier 100 may be a tank type that includes a water supply tank and supplies water from the water supply tank to the water storage tray 4. In the humidifier 100 including the water supply tank, the capacity of the water storage tray 4 may be small.
　また、加湿機１００において、上部に電気稼働部２が配置され、下部に貯水トレイ４が配置される。しかしながら、電気稼働部２および貯水トレイ４の配置は上記の構成に限らず、加湿機１００において、上部に貯水トレイ４が配置され、下部に電気稼働部２が配置されてもよい。このように構成された加湿機１００にも、後述する実施形態１～５の構成を適用することが可能である。 に お い て Further, in the humidifier 100, the electric operation unit 2 is arranged at the upper part, and the water storage tray 4 is arranged at the lower part. However, the arrangement of the electric operating unit 2 and the water storage tray 4 is not limited to the above-described configuration. In the humidifier 100, the water storage tray 4 may be disposed at the upper part and the electric operating unit 2 may be disposed at the lower part. The configurations of Embodiments 1 to 5 described later can be applied to the humidifier 100 configured as described above.
　上部に貯水トレイ４が配置されるとともに下部に電気稼働部２が配置された構成は、例えば、下部の電気稼働部２のシロッコファン２２から上部の貯水トレイ４に向けて吹き出した空気を、貯水トレイ４の側方に設けられた通風路を通じて貯水トレイ４の上方に導き、気化フィルタ５によって水分を含ませた後に、筐体１の上端から放出するようにしてもよい。このような構成は、あくまでも一例であって、他にも採り得る構成があることを付言しておく。 The configuration in which the water storage tray 4 is disposed in the upper portion and the electric operating portion 2 is disposed in the lower portion is, for example, a configuration in which air blown from the sirocco fan 22 of the lower electric operating portion 2 toward the upper water storage tray 4 is stored in the lower portion. The water may be guided from above the water storage tray 4 through an air passage provided on the side of the tray 4, and may be discharged from the upper end of the housing 1 after moisture is contained by the vaporization filter 5. Such a configuration is merely an example, and it should be added that there are other possible configurations.
　また、以降に説明する実施形態１～５は、加湿機１００に限らず、それぞれ空気調和機である、除湿機、除湿機能および／または加湿機能を有する空気清浄機などにも適用可能である。除湿機は、除湿の結果生じた水を貯留するために貯水トレイ４と同様な貯水トレイを備えている。また、この貯水トレイは、除湿で生じたすべての水を貯留するように大容量に構成されている。 実 施 Embodiments 1 to 5 described below are not limited to the humidifier 100, and can be applied to an air conditioner, an air purifier having a dehumidifying function and / or a humidifying function. The dehumidifier has a water storage tray similar to the water storage tray 4 for storing water generated as a result of dehumidification. Further, the water storage tray is configured to have a large capacity so as to store all water generated by dehumidification.
　除湿機は、コンプレッサ式、デシカント式、ハイブリッド式などの方式があり、それぞれの方式で、取り込んだ空気から水分を除去する除湿部（蒸発器、熱交換器など）を備えるが、筐体内部で空気の流れを生じるためにファンも備える。このため、除湿機は、上述の加湿機１００と同様なファンと貯水トレイとの配置構造を採ることもある。 Dehumidifiers are available in compressor, desiccant, and hybrid types. Each type has a dehumidifier (evaporator, heat exchanger, etc.) that removes moisture from the air taken in. A fan is also provided to create airflow. For this reason, the dehumidifier may adopt the same arrangement structure of the fan and the water storage tray as the humidifier 100 described above.
　〔実施形態１〕
　本発明の実施形態１について、図３、図４および図６に基づいて説明すれば、以下のとおりである。 [Embodiment 1]
Embodiment 1 of the present invention will be described below with reference to FIGS. 3, 4, and 6. FIG.
　図６は、本実施形態に係る加湿機１００における電気稼働部２に含まれる保持フレーム２１の構造を示す斜視図である。 FIG. 6 is a perspective view showing the structure of the holding frame 21 included in the electric operating unit 2 in the humidifier 100 according to the present embodiment.
　図６に示すように、モータ保持部２１６は、内周壁２１７ｂの内周側に設けられている。モータ保持部２１６は、ボス２１６ａと、中央保持部２１６ｂとを有している。 モ ー タ As shown in FIG. 6, the motor holding portion 216 is provided on the inner peripheral side of the inner peripheral wall 217b. The motor holding part 216 has a boss 216a and a center holding part 216b.
　ボス２１６ａは、モータ２３をネジ固定するために、中央保持部２１６ｂを中心に、間隔をおいた３箇所に設けられている。また、モータ２３は、図示しないモータアングルを介して中央保持部２１６ｂに固定されている。シロッコファン２２は、モータ２３の回転軸に締結されている。 The bosses 216a are provided at three places around the center holding portion 216b to fix the motor 23 with screws. Further, the motor 23 is fixed to the center holding portion 216b via a motor angle (not shown). The sirocco fan 22 is fastened to a rotating shaft of a motor 23.
　図６に示すように、保持フレーム２１における送風路２１７は、上述のように、外周壁２１７ａ、内周壁２１７ｂおよび側壁２１７ｃを有している。 よ う As shown in FIG. 6, the air passage 217 in the holding frame 21 has the outer peripheral wall 217a, the inner peripheral wall 217b, and the side wall 217c as described above.
　図３および図４にも示すように、内周壁２１７ｂは、シロッコファン２２を取り囲むように、通気口２１４における左部側の端部の付近から概ね３００°の範囲で円形状に形成されている。内周壁２１７ｂが形成される範囲は、上記の範囲に限定されない。 As shown in FIGS. 3 and 4, the inner peripheral wall 217 b is formed in a circular shape within a range of approximately 300 ° from the vicinity of the left end of the ventilation hole 214 so as to surround the sirocco fan 22. . The range in which the inner peripheral wall 217b is formed is not limited to the above range.
　内周壁２１７ｂは、貯水トレイ４に最も近い側である、通気口２１４の左部側端部の付近の一端部が最も高くなるように形成されている。また、内周壁２１７ｂは、図４において矢印にて示す空気が導かれる方向（図３に矢印にて示すシロッコファン２２の回転方向）の逆方向に沿って徐々に低くなるように形成されている。 The inner peripheral wall 217b is formed so that one end near the left end of the ventilation hole 214, which is the side closest to the water storage tray 4, is the highest. In addition, the inner peripheral wall 217b is formed so as to gradually decrease along the direction opposite to the direction in which the air shown by the arrow in FIG. 4 is guided (the rotation direction of the sirocco fan 22 shown by the arrow in FIG. 3). .
　図４に示すように、外周壁２１７ａは、内周壁２１７ｂの外周側と間隔をおいて、通気口２１４における右部側の端部から通気口２１４における左部側の端部の付近まで形成されている。外周壁２１７ａと内周壁２１７ｂとの間の間隔は、始端部で最も狭く、かつ通気口２１４に最も近い位置で最も広く、空気が導かれる方向に沿って徐々に広くなる。 As shown in FIG. 4, the outer peripheral wall 217a is formed from the right end of the vent 214 to the vicinity of the left end of the vent 214 at a distance from the outer peripheral side of the inner peripheral wall 217b. ing. The distance between the outer peripheral wall 217a and the inner peripheral wall 217b is the narrowest at the start end, the widest at the position closest to the vent 214, and gradually widens along the direction in which air is introduced.
　側壁２１７ｃは、外周壁２１７ａおよび内周壁２１７ｂにおける筐体１の中心側の端部の間に設けられている。側壁２１７ｃは、鉛直方向の直線と前後方向の直線とを含む平面上に形成されている。 The side wall 217c is provided between the outer peripheral wall 217a and the inner peripheral wall 217b between the ends on the center side of the housing 1. The side wall 217c is formed on a plane including a vertical straight line and a front-rear straight line.
　送風路２１７は、空気が導かれる方向に沿って幅が徐々に広がるように形成されることにより、空気の流れを整流するスクロールケーシングを構成している。 (4) The air passage 217 forms a scroll casing that straightens the flow of air by being formed so as to gradually widen in the direction in which the air is guided.
　上記のように構成される本実施形態の加湿機１００は、何からの外力を受けて転倒する可能性がある。加湿機１００は、左右方向よりも幅が狭い前後方向に倒れやすい。加湿機１００が転倒すると、貯水トレイ４内の水が流れ出る。 湿 The humidifier 100 of the present embodiment configured as described above may fall down by receiving any external force. The humidifier 100 is likely to fall in the front-back direction, which is narrower than the left-right direction. When the humidifier 100 falls, the water in the water storage tray 4 flows out.
　加湿機１００がシロッコファン２２を下側にして転倒すると、貯水トレイ４から流れ出た水が通気口２１４を介して送風路２１７内へ浸入する。この状態では、シロッコファン２２が下側に位置しているので、浸入した水は、シロッコファン２２に対向する筐体１の内壁面を流れる。したがって、この状態では、シロッコファン２２の背後（上側）に配置された電気部品の側に水は浸入しない。 When the humidifier 100 falls down with the sirocco fan 22 down, the water flowing out of the water storage tray 4 infiltrates into the air passage 217 through the ventilation hole 214. In this state, since the sirocco fan 22 is located on the lower side, the water that has entered flows on the inner wall surface of the housing 1 facing the sirocco fan 22. Therefore, in this state, water does not enter the side of the electric components arranged behind (upper side) the sirocco fan 22.
　一方、加湿機１００がシロッコファン２２を上側にして転倒すると、貯水トレイ４から流れ出た水が通気口２１４を介して送風路２１７内へ浸入する。この状態では、シロッコファン２２が上側に位置しているので、浸入した水は、送風路２１７内に流れ込む。しかしながら、内周壁２１７ｂによって、シロッコファン２２側への水の浸入が大幅に抑制される。 On the other hand, when the humidifier 100 falls down with the sirocco fan 22 facing upward, the water flowing out of the water storage tray 4 infiltrates into the air passage 217 through the ventilation hole 214. In this state, since the sirocco fan 22 is located on the upper side, the water that has entered flows into the air passage 217. However, the infiltration of water into the sirocco fan 22 is greatly suppressed by the inner peripheral wall 217b.
　特に、転倒の衝撃によって通気口２１４の付近では水が大きく波打つ。これに対し、内周壁２１７ｂの通気口２１４付近が最も高くなるように形成されている。これにより、大きく波打った水がシロッコファン２２側へ浸入することを抑制することができる。 水 Particularly, the water undulates in the vicinity of the vent 214 due to the impact of falling. In contrast, the inner peripheral wall 217b is formed so as to be highest in the vicinity of the vent 214. Accordingly, it is possible to suppress the greatly wavy water from entering the sirocco fan 22 side.
　したがって、加湿機１００が転倒しても、シロッコファン２２側からシロッコファン２２の背後に配置された電気部品へは、ほとんど水が浸入しない。よって、加湿機１００の転倒時に溢れた水による電気部品の損傷を防止することができる。 Therefore, even if the humidifier 100 falls, almost no water penetrates from the sirocco fan 22 side to the electric components arranged behind the sirocco fan 22. Therefore, it is possible to prevent the electric components from being damaged by the water overflowing when the humidifier 100 falls.
　また、内周壁２１７ｂが、送風路２１７において空気が導かれる方向の逆方向に沿って低くなるように形成されているので、シロッコファン２２の送風性能の低下を抑制することができる。低い内周壁２１７ｂ（７～８ｍｍ程度の高さ）は、シロッコファン２２の送風性能を高めることができるので、好ましい。 Further, since the inner peripheral wall 217b is formed so as to be lower in the direction opposite to the direction in which the air is led in the air passage 217, it is possible to suppress a decrease in the air blowing performance of the sirocco fan 22. The low inner peripheral wall 217b (height of about 7 to 8 mm) is preferable because the blowing performance of the sirocco fan 22 can be improved.
　〔実施形態２〕
　本発明の実施形態２について、図７および図８に基づいて説明すれば、以下のとおりである。なお、説明の便宜上、実施形態１にて説明した構成要素と同等の機能を有する構成要素については、同じ符号を付記し、その説明を省略する。また、本実施形態では、実施形態１と異なる部分について説明する。 [Embodiment 2]
Embodiment 2 of the present invention will be described below with reference to FIGS. 7 and 8. Note that, for convenience of description, components having the same functions as those described in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. In the present embodiment, portions different from the first embodiment will be described.
　図７は、本実施形態に係る加湿機１００が通常に配置されているときの電気稼働部２における保持フレーム２１の状態を示す図であり、図７の（ａ）は斜視図であり、図７の（ｂ）は下面図である。図８は、本実施形態に係る加湿機１００が転倒したときの電気稼働部２における保持フレーム２１の状態を示す図であり、図８の（ａ）は斜視図であり、図８の（ｂ）は下面図である。 FIG. 7 is a diagram illustrating a state of the holding frame 21 in the electric operating unit 2 when the humidifier 100 according to the present embodiment is normally arranged, and FIG. 7A is a perspective view. (B) of FIG. 7 is a bottom view. FIG. 8 is a diagram illustrating a state of the holding frame 21 in the electric operating unit 2 when the humidifier 100 according to the present embodiment has fallen, and FIG. 8A is a perspective view and FIG. () Is a bottom view.
　図７の（ａ）および（ｂ）に示すように、本実施形態における保持フレーム２１には、上述のグリル２１５に代えて複数のシャッタ２１８（開閉部材）が設けられている。 保持 As shown in FIGS. 7A and 7B, the holding frame 21 in the present embodiment is provided with a plurality of shutters 218 (opening / closing members) instead of the grill 215 described above.
　シャッタ２１８は、互いに平行に並ぶように通気口２１４に配置されている。シャッタ２１８は、細長い長方形を成す板状の部材であり、両端に軸が設けられている。シャッタ２１８は、両端の軸が保持フレーム２１において通気口２１４を形成する壁面に差し込まれることにより、当該壁面に回動可能に支持されている。 The shutters 218 are arranged in the ventilation holes 214 so as to be arranged in parallel with each other. The shutter 218 is a plate-shaped member having an elongated rectangular shape, and shafts are provided at both ends. The shutter 218 is rotatably supported on the wall surface by inserting the shafts at both ends into the wall surface forming the ventilation hole 214 in the holding frame 21.
　加湿機１００が正常に配置されている状態では、図７の（ａ）および（ｂ）に示すように、シャッタ２１８は垂下して通気口２１４を開く位置にある。また、シロッコファン２２が上側に位置するように加湿機１００が転倒した状態では、図８の（ａ）および（ｂ）に示すように、シャッタ２１８は通気口２１４を閉じるように回動する。 (7) In a state where the humidifier 100 is normally arranged, the shutter 218 is at a position where the shutter 218 hangs down to open the ventilation hole 214 as shown in FIGS. 7 (a) and 7 (b). In addition, when the humidifier 100 is overturned so that the sirocco fan 22 is located on the upper side, the shutter 218 rotates so as to close the ventilation port 214 as shown in FIGS.
　このように加湿機１００が転倒した状態では、シャッタ２１８が通気口２１４を閉じる。これにより、貯水トレイ４から流れ出た水が通気口２１４を通じて送風路２１７に浸入することを抑制することができる。 で は When the humidifier 100 falls over in this manner, the shutter 218 closes the vent 214. Thereby, it is possible to suppress the water flowing out of the water storage tray 4 from entering the air passage 217 through the ventilation hole 214.
　また、多数のシャッタ２１８を設けることで、より密に通気口２１４を閉じることができる。それゆえ、通気口２１４への水の浸入を大幅に少なくすることで、内周壁２１７ｂにおける通気口２１４付近の高さを低くすることができる。したがって、シロッコファン２２の送風性能の低下を抑制することができる。 通 気 Further, by providing a large number of shutters 218, the ventilation holes 214 can be closed more densely. Therefore, the height of the inner peripheral wall 217b in the vicinity of the vent 214 can be reduced by greatly reducing the intrusion of water into the vent 214. Therefore, it is possible to suppress a decrease in the blowing performance of the sirocco fan 22.
　なお、多数のシャッタ２１８に代えて、１枚の大きい板状のシャッタを通気口２１４に回動可能に設けてもよい。ただし、このような構成では、下方にシャッタが開閉する比較的大きい空間が必要であるだけでなく、シャッタ２１８のように通気口２１４を密に閉じることができない。したがって、多数のシャッタ２１８によって通気口２１４を閉じる構成が好ましいと言える。 Note that one large plate-shaped shutter may be rotatably provided in the ventilation port 214 instead of the large number of shutters 218. However, such a configuration not only requires a relatively large space below which the shutter can be opened and closed, but also does not allow the air vent 214 to be closed tightly like the shutter 218 does. Therefore, it can be said that a configuration in which the air vent 214 is closed by a number of shutters 218 is preferable.
　〔実施形態３〕
　本発明の実施形態３について、図９および図１０に基づいて説明すれば、以下のとおりである。なお、説明の便宜上、実施形態１にて説明した構成要素と同等の機能を有する構成要素については、同じ符号を付記し、その説明を省略する。また、本実施形態では、実施形態１と異なる部分について説明する。 [Embodiment 3]
Embodiment 3 of the present invention will be described below with reference to FIGS. 9 and 10. Note that, for convenience of description, components having the same functions as those described in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. In the present embodiment, portions different from the first embodiment will be described.
　図９は、本実施形態に係る加湿機１００が通常に配置されているときの電気稼働部２における保持フレーム２１の状態を示す側面図である。図１０は、本実施形態に係る加湿機１００が転倒したときの電気稼働部２における保持フレーム２１の状態を示す側面図である。 FIG. 9 is a side view showing a state of the holding frame 21 in the electric operating unit 2 when the humidifier 100 according to the present embodiment is normally arranged. FIG. 10 is a side view illustrating a state of the holding frame 21 in the electric operating unit 2 when the humidifier 100 according to the present embodiment has fallen.
　図９に示すように、本実施形態における保持フレーム２１は、さらにシャッタ２１８Ａ（開閉部材）を備えている。 As shown in FIG. 9, the holding frame 21 according to the present embodiment further includes a shutter 218A (opening / closing member).
　シャッタ２１８Ａは、送風路２１７に配置された板状の部材である。図９に示すように、シャッタ２１８Ａが外周壁２１７ａに沿った位置にある（送風路２１７を開いた）状態で、シャッタ２１８Ａの可動側の端部は通気口２１４の近傍に位置する。また、シャッタ２１８Ａが送風路２１７を開いた状態で、シャッタ２１８Ａの支持側の端部は、外周壁２１７ａにおける通気口２１４よりも上流側の所定位置で軸１０を中心に回動可能となるように支持されている。 The shutter 218A is a plate-shaped member arranged in the air passage 217. As shown in FIG. 9, when the shutter 218A is located along the outer peripheral wall 217a (the air passage 217 is opened), the movable end of the shutter 218A is located near the ventilation hole 214. When the shutter 218A opens the air passage 217, the end on the supporting side of the shutter 218A is rotatable about the shaft 10 at a predetermined position on the outer peripheral wall 217a at a position upstream of the ventilation port 214. It is supported by.
　シャッタ２１８Ａの可動側の端部は、図１０に示すように、シャッタ２１８Ａが送風路２１７を閉じた状態で内周壁２１７ｂに沿うように、両面に対して傾斜する傾斜面を有している。 As shown in FIG. 10, the movable end of the shutter 218A has an inclined surface that is inclined with respect to both surfaces so that the shutter 218A follows the inner peripheral wall 217b with the air passage 217 closed.
　加湿機１００が正常に配置されている状態では、図９に示すように、シャッタ２１８Ａは送風路２１７を開く開位置にある。また、シロッコファン２２が上側に位置するように加湿機１００が転倒した状態では、図１０に示すように、シャッタ２１８Ａは、転倒時の衝撃で開位置から通気口２１４を閉じる閉位置まで回動する。シャッタ２１８Ａは、転倒時の衝撃によって閉位置まで回動しない場合でも、通気口２１４から流れ込む水の圧力で閉位置まで回動する。 で は When the humidifier 100 is normally arranged, the shutter 218A is in an open position for opening the air passage 217 as shown in FIG. Further, in a state where the humidifier 100 is overturned so that the sirocco fan 22 is located on the upper side, as shown in FIG. 10, the shutter 218A rotates from the open position to the closed position to close the air vent 214 due to the impact at the time of overturn. I do. Even when the shutter 218A does not rotate to the closed position due to the impact at the time of falling, the shutter 218A rotates to the closed position due to the pressure of the water flowing from the vent 214.
　このように加湿機１００が転倒した状態では、シャッタ２１８Ａが送風路２１７を閉じる。これにより、貯水トレイ４から流れ出た水が通気口２１４を通じて送風路２１７に浸入しても、シャッタ２１８Ａより先への水の浸入を大幅に抑制することができる。 で は When the humidifier 100 falls over, the shutter 218A closes the air passage 217. Accordingly, even if the water flowing out of the water storage tray 4 enters the air passage 217 through the ventilation port 214, the intrusion of water beyond the shutter 218A can be significantly suppressed.
　また、シャッタ２１８Ａと内周壁２１７ｂとの隙間から僅かに水が浸入しても、その水の量は少ない。それゆえ、内周壁２１７ｂによってシロッコファン２２側への水の浸入を十分阻止することができる。 Also, even if water intrudes slightly from the gap between the shutter 218A and the inner peripheral wall 217b, the amount of the water is small. Therefore, it is possible to sufficiently prevent water from entering the sirocco fan 22 by the inner peripheral wall 217b.
　また、送風路２１７における水の浸入を防ぐために必要な部材が１つのシャッタ２１８Ａである。これにより、部品点数を少なくして、加湿機１００の価格上昇を抑えることができる。 {Circle around (1)} One member required to prevent water from entering the air passage 217 is one shutter 218A. Thereby, the number of parts can be reduced and the price increase of the humidifier 100 can be suppressed.
　〔実施形態４〕
　本発明の実施形態４について、図１１に基づいて説明すれば、以下のとおりである。なお、説明の便宜上、実施形態１にて説明した構成要素と同等の機能を有する構成要素については、同じ符号を付記し、その説明を省略する。また、本実施形態では、実施形態１と異なる部分について説明する。 [Embodiment 4]
Embodiment 4 of the present invention is described below with reference to FIG. Note that, for convenience of description, components having the same functions as those described in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. In the present embodiment, portions different from the first embodiment will be described.
　図１１は、本実施形態に係る加湿機１００における保持フレーム２１の構造を示す側面図である。 FIG. 11 is a side view showing the structure of the holding frame 21 in the humidifier 100 according to the present embodiment.
　図１１に示すように、本実施形態における保持フレーム２１は、ハニカム構造２１９（水流抑制部材）を備えている。 保持 As shown in FIG. 11, the holding frame 21 in the present embodiment has a honeycomb structure 219 (water flow suppressing member).
　ハニカム構造２１９は、内周壁２１７ｂの最も高さの低い部位より低い高さを有し、かつ正六角形の形状を成す壁状の基本構造が隙間なく並べられた構造である。ハニカム構造２１９は、側壁２１７ｃ上における通気口２１４付近から保持フレーム２１の上端付近までの範囲に設けられている。なお、ハニカム構造２１９を構成する基本構造は、隙間なく並べることができれば、正六角形以外の形状（正三角形、正方形など）であってもよい。 The honeycomb structure 219 has a height lower than the lowest portion of the inner peripheral wall 217b, and is a structure in which wall-shaped basic structures having a regular hexagonal shape are arranged without gaps. The honeycomb structure 219 is provided in a range from the vicinity of the ventilation hole 214 on the side wall 217c to the vicinity of the upper end of the holding frame 21. Note that the basic structure forming the honeycomb structure 219 may have a shape other than a regular hexagon (regular triangle, square, or the like) as long as it can be arranged without gaps.
　シロッコファン２２が上側に位置するように加湿機１００が転倒した状態では、貯水トレイ４から通気口２１４を通じて浸入した水は、ハニカム構造２１９の各基本構造の内部に溜め込まれる。それゆえ、ハニカム構造２１９において水流（水の勢いおよび量）が抑制されるので、送風路２１７の奥にまで水が浸入することをほぼ回避することができる。したがって、加湿機１００の転倒時において、より確実にシロッコファン２２側への浸入を防止することが可能になる。 In the state where the humidifier 100 is overturned so that the sirocco fan 22 is located on the upper side, the water that has entered from the water storage tray 4 through the vent 214 is stored inside each basic structure of the honeycomb structure 219. Therefore, since the water flow (power and amount of water) is suppressed in the honeycomb structure 219, it is possible to substantially prevent water from penetrating deep into the ventilation path 217. Therefore, when the humidifier 100 falls, it is possible to more reliably prevent the humidifier 100 from entering the sirocco fan 22 side.
　なお、水流抑制部材としては、ハニカム構造２１９以外に、送風路２１７において間隔をおいて複数の仕切部材を設けてもよい。仕切部材は、例えば、ハニカム構造２１９と同程度の高さを有し、放射状（シロッコファン２２の中心から伸びる放射線上の位置）に配置されている。このような仕切部材によれば、仕切部材の間に水が溜め込まれるので、送風路２１７における水流を抑制することができる。 As the water flow suppressing member, a plurality of partition members may be provided at intervals in the air passage 217 in addition to the honeycomb structure 219. The partition member has, for example, a height approximately equal to that of the honeycomb structure 219 and is arranged radially (a position on a radiation extending from the center of the sirocco fan 22). According to such a partition member, since water is stored between the partition members, the water flow in the air passage 217 can be suppressed.
　なお、本実施形態の構成を、上述の実施形態２または３の構成に適用してもよい。 Note that the configuration of the present embodiment may be applied to the configuration of the above-described second or third embodiment.
　〔実施形態５〕
　本発明の実施形態５について、図１２に基づいて説明すれば、以下のとおりである。なお、説明の便宜上、実施形態１にて説明した構成要素と同等の機能を有する構成要素については、同じ符号を付記し、その説明を省略する。また、本実施形態では、実施形態１と異なる部分について説明する。 [Embodiment 5]
Embodiment 5 of the present invention will be described below with reference to FIG. Note that, for convenience of description, components having the same functions as those described in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. In the present embodiment, portions different from the first embodiment will be described.
　図１２の（ａ）は、本実施形態に係る加湿機１００における貯水トレイ４の構成を示す平面図である。図１２の（ｂ）は、図１２の（ａ）のＡ－Ａ線矢視断面図である。 （(A) of FIG. 12 is a plan view showing a configuration of the water storage tray 4 in the humidifier 100 according to the present embodiment. FIG. 12B is a cross-sectional view taken along the line AA of FIG.
　図１２の（ａ）および（ｂ）に示すように、貯水トレイ４において、フロート６（板部材）が配置されている。フロート６は、貯水トレイ４に貯えられた水に浮くように、例えば発泡スチロールによって形成されている。フロート６は、後述する加湿機１００の転倒時に、通気口２１４側に移動可能となる位置に配置されている。 フ ロ ー As shown in FIGS. 12A and 12B, a float 6 (plate member) is arranged in the water storage tray 4. The float 6 is formed of, for example, styrofoam so as to float on the water stored in the water storage tray 4. The float 6 is arranged at a position where the float 6 can be moved toward the vent 214 when the humidifier 100 described below falls.
　加湿機１００が正常に配置されている状態では、図１２の（ｂ）に示すように、フロート６は貯水トレイ４において水面上に浮いている。また、シロッコファン２２が上側に位置するように加湿機１００が転倒した状態では、貯水トレイ４が横転するため、フロート６は、貯水トレイ４から流れ出た水によって押されて、保持フレーム２１の底面における通気口２１４まで移動する。また、貯水トレイ４から水が流れ出ている間は、フロート６が水によって保持フレーム２１の底面に押さえ込まれている。これにより、フロート６が通気口２１４を閉じるので、通気口２１４から送風路２１７への水の浸入が抑制される。 で は In a state where the humidifier 100 is normally disposed, the float 6 is floating on the water surface in the water storage tray 4 as shown in FIG. Further, when the humidifier 100 is overturned so that the sirocco fan 22 is positioned on the upper side, the water storage tray 4 rolls over, so that the float 6 is pushed by the water flowing out of the water storage tray 4, and the bottom surface of the holding frame 21. To the vent 214 at. While the water is flowing out of the water storage tray 4, the float 6 is pressed against the bottom surface of the holding frame 21 by the water. Thereby, since the float 6 closes the ventilation port 214, intrusion of water from the ventilation port 214 into the air passage 217 is suppressed.
　なお、本実施形態の構成を、上述の実施形態２、３または４の構成に適用してもよい。 Note that the configuration of the present embodiment may be applied to the configuration of the above-described second, third, or fourth embodiment.
　〔まとめ〕
　本発明の態様１に係る空気調和機は、水を貯留する貯水トレイ４と、空気の流れを生成するファン（シロッコファン２２）と、前記ファンによって外部から取り込まれた空気を前記ファンの周囲に沿って前記貯水トレイ４に導く送風路２１７と、を備え、前記送風路２１７が、前記ファンを取り囲むように設けられた壁体（内周壁２１７ｂ）を有し、前記壁体が、前記貯水トレイ４に最も近い側が最も高く、かつ前記送風路２１７において空気が導かれる方向の逆方向に沿って低くなるように形成されている。 [Summary]
The air conditioner according to the first aspect of the present invention includes a water storage tray 4 for storing water, a fan (sirocco fan 22) for generating an air flow, and air taken in from outside by the fan around the fan. And an air passage 217 that guides the water storage tray 4 along the water storage tray 4. The air passage 217 has a wall (inner peripheral wall 217b) provided so as to surround the fan, and the wall is formed of the water storage tray. 4 is formed so as to be highest on the side closest thereto and to decrease along the direction opposite to the direction in which air is introduced in the air passage 217.
　上記の構成によれば、空気調和機が転倒時したために貯水トレイからこぼれた水が送風路内へ浸入しても、壁体によって、ファンへの水の浸入が大幅に抑制される。特に、転倒の衝撃によって送風路における貯水トレイの付近では水が大きく波打つが、壁体が、貯水トレイに最も近い側が最も高くなるように形成されているので、このような水がファン側へ浸入することを抑制することができる。また、壁体が、送風路において空気が導かれる方向の逆方向に沿って低くなるように形成されているので、ファンの送風性能の低下を抑制することができる。 According to the configuration described above, even if water spilled from the water storage tray enters the air duct due to the air conditioner having fallen over, the wall body greatly suppresses water from entering the fan. In particular, the water ripples greatly near the water storage tray in the ventilation path due to the impact of the fall, but since the wall is formed so as to be highest on the side closest to the water storage tray, such water enters the fan side. Can be suppressed. Further, since the wall is formed so as to be lower in the direction opposite to the direction in which the air is guided in the airflow path, it is possible to suppress a reduction in the air blowing performance of the fan.
　したがって、空気調和機が転倒しても、ファン側からファンの背後に配置された電気部品へは、ほとんど水が浸入しない。よって、空気調和機の転倒時に溢れた水による電気部品の損傷を防止することができる。 Therefore, even if the air conditioner falls down, almost no water enters the electric components arranged behind the fan from the fan side. Therefore, it is possible to prevent the electric components from being damaged by the water overflowing when the air conditioner falls.
　本発明の態様２に係る空気調和機は、上記態様１において、空気調和機が正常に配置された状態で垂下して前記送風路２１７の空気排出口（通気口２１４）を開く一方、空気調和機が転倒した状態で前記空気排出口を閉じるように回動可能に設けられた開閉部材（シャッタ２１８）をさらに備えていてもよい。 An air conditioner according to an aspect 2 of the present invention is the air conditioner according to the above aspect 1, wherein the air conditioner is hung down in a state where the air conditioner is normally disposed to open the air discharge port (vent 214) of the air passage 217. An opening / closing member (shutter 218) rotatably provided so as to close the air outlet when the machine is overturned may be further provided.
　上記の構成によれば、空気調和機が転倒時したために貯水トレイから水がこぼれ出ても、空気排出口が開閉部材によって閉じられる。これにより、水が空気排出口を通じて送風路に浸入することを抑制することができる。 According to the above configuration, even if water spills out of the water storage tray due to the air conditioner having fallen over, the air discharge port is closed by the opening / closing member. Thus, it is possible to prevent water from entering the air passage through the air outlet.
　本発明の態様３に係る空気調和機は、上記態様１において、空気調和機が正常に配置された状態で前記送風路２１７の所定位置において前記送風路２１７を開く位置と、空気調和機が転倒した状態で前記所定位置において前記送風路２１７を閉じる位置との間を回動するように設けられた開閉部材（シャッタ２１８Ａ）をさらに備えていてもよい。 An air conditioner according to an aspect 3 of the present invention is the air conditioner according to the above aspect 1, wherein the air conditioner is opened at a predetermined position of the air passage 217 in a state where the air conditioner is normally disposed, and the air conditioner is turned over. An opening / closing member (shutter 218A) provided to rotate between the predetermined position and the position for closing the air passage 217 in the above state may be further provided.
　上記の構成によれば、空気調和機が転倒時したために貯水トレイから水がこぼれ出ても、送風路が所定位置において開閉部材によって閉じられる。これにより、水が送風路に浸入しても、開閉部材より先への水の浸入を大幅に抑制することができる。 According to the above configuration, even when water spills out of the water storage tray due to the air conditioner having fallen over, the air passage is closed by the opening / closing member at the predetermined position. Thereby, even if water infiltrates the airflow path, it is possible to significantly suppress intrusion of water before the opening / closing member.
　本発明の態様４に係る空気調和機は、上記態様１から３のいずれかにおいて、空気調和機の転倒時に前記貯水トレイ４から前記送風路２１７に浸入する水の勢いおよび量を抑制する水流抑制部材（ハニカム構造２１９）をさらに備えていてもよい。 The air conditioner according to Aspect 4 of the present invention is the air conditioner according to any one of Aspects 1 to 3, wherein the water flow suppressing the momentum and the amount of water entering from the water storage tray 4 into the air passage 217 when the air conditioner falls down. A member (honeycomb structure 219) may be further provided.
　上記の構成によれば、空気調和機の転倒時に貯水トレイからこぼれ出た水が送風路に浸入しても、送風路の奥にまで浸入することをほぼ回避することができる。したがって、空気調和機の転倒時において、より確実にシロッコファン２２側への浸入を防止することが可能になる。 According to the above configuration, even if the water spilled out of the water storage tray when the air conditioner falls over enters the ventilation path, it can be substantially prevented from penetrating deep into the ventilation path. Therefore, it is possible to more reliably prevent the air conditioner from entering the sirocco fan 22 when the air conditioner falls.
　本発明の態様５に係る空気調和機は、上記態様１から４のいずれかにおいて、前記貯水トレイ４に貯留された水に浮かぶ板部材（フロート６）をさらに備え、前記板部材が、空気調和機の転倒時に前記送風路２１７の空気排出口へ移動可能となる位置に配置されていてもよい。 An air conditioner according to a fifth aspect of the present invention is the air conditioner according to any one of the first to fourth aspects, further comprising a plate member (float 6) floating on the water stored in the water storage tray 4, wherein the plate member is an air conditioner. It may be arranged at a position where it can be moved to the air outlet of the air passage 217 when the machine falls.
　上記の構成によれば、板部材は、貯水トレイからこぼれた水によって押されて空気排出口まで移動する。また、貯水トレイから水が流れ出ている間は、板部材が水によって押されて空気排出口を閉じる。これにより、空気排出口から送風路への水の浸入を抑制することができる。 According to the above configuration, the plate member is pushed by the water spilled from the water storage tray and moves to the air discharge port. Further, while the water is flowing out of the water storage tray, the plate member is pushed by the water to close the air outlet. Thereby, invasion of water from the air discharge port to the air passage can be suppressed.
　本発明の態様６に係る空気調和機は、上記態様１から５のいずれかにおいて、前記貯水トレイ４が加湿に用いるすべての水または除湿で生じたすべての水を貯留してもよい。 In the air conditioner according to the sixth aspect of the present invention, in any one of the first to fifth aspects, the water storage tray 4 may store all water used for humidification or all water generated by dehumidification.
　給水タンクを用いないで貯水トレイに大量の水を貯留する空気調和機の転倒時には、大量の水がファンの側に流れ込む。上記の構成によれば、上述のように、送風路への水の浸入または送風路における水の浸入の抑制を図ることによって、大量の水が貯水トレイから流れ出ても、ファン側への水の浸入を回避することができる。 空 気 When the air conditioner that stores a large amount of water in the water storage tray without using the water supply tank falls, a large amount of water flows into the fan side. According to the above configuration, as described above, even if a large amount of water flows out of the water storage tray, water is prevented from flowing to the fan side by suppressing water infiltration into the ventilation path or water infiltration in the ventilation path. Invasion can be avoided.
