Description

本発明は、貯水槽に一部が浸水した加湿フィルタに通風して加湿を行う加湿器に関する。 The present invention relates to a humidifier that performs humidification by passing air through a humidifying filter partially immersed in a water storage tank.

貯水槽に一部が浸水した加湿フィルタに空気を通流させることにより、空気を加湿する加湿器が提案されている（例えば、特許文献１）。特許文献１に係る加湿器は、上部が開口した貯水槽と、水位を一定に保持するように貯水槽に水を供給する給水タンクと、貯水槽に下部が浸水し、上部を空気が通過するように保持された加湿フィルタとを備える。貯水槽の底部には、給水タンクの給水口の縁に倣って形成された円形の凹状をなす受水部と、加湿フィルタの下部が浸かるように形成された横長凹部と、受水部及び横長凹部を連通し、受水部で受けた水を横長凹部へ流す通水溝とが形成されている。給水タンクから貯水槽への給水は、受水部の水位が給水口に達するまで続き、水位が給水口に達すると自動的に停止する。加湿が進み、貯水槽の水位が低下すると、再び貯水槽への給水が行われ、水位が一定に保たれる。給水は、通水溝と給水口との隙間を通じて給水タンク内に入り込んだ空気と、該給水タンク内の水とが置換されることによって行われる。特許文献１によれば、貯水槽の底部全体に水を貯留せず、受水部及び通水溝を用いて横長凹部へ水を供給するように構成してあるため、貯水槽に貯留される水の量を抑えることができ、転倒時に貯水槽から溢れる水の量を少なくすることができる。 There has been proposed a humidifier that humidifies air by allowing air to flow through a humidifying filter partially immersed in a water storage tank (for example, Patent Document 1). The humidifier according to Patent Document 1 has a water storage tank whose upper part is open, a water supply tank that supplies water to the water storage tank so as to keep the water level constant, a lower part of the water tank is submerged, and air passes through the upper part. And a humidifying filter held in this manner. At the bottom of the water storage tank, a water receiving portion having a circular recess formed following the edge of the water supply port of the water supply tank, a horizontally long recess formed so that the lower portion of the humidifying filter is immersed, a water receiving portion and a horizontally long A water passage groove is formed in which the concave portion communicates and the water received by the water receiving portion flows into the horizontally long concave portion. Water supply from the water supply tank to the water storage tank continues until the water level of the water receiving part reaches the water supply port, and automatically stops when the water level reaches the water supply port. When humidification progresses and the water level in the water storage tank decreases, water is supplied to the water storage tank again, and the water level is kept constant. The water supply is performed by replacing the air that has entered the water supply tank through the gap between the water flow groove and the water supply port with the water in the water supply tank. According to Patent Document 1, water is not stored in the entire bottom portion of the water tank, but is configured to supply water to the horizontally elongated recess using the water receiving portion and the water flow groove, and thus is stored in the water tank. The amount of water can be suppressed, and the amount of water overflowing from the water storage tank at the time of falling can be reduced.

9 is a perspective view showing a configuration example of the water storage tank 2, FIG. 10 is a plan view showing a configuration example of the water storage tank 2, and FIG. 11 is a sectional view taken along line XI-XI in FIG. The water reservoir 2 is open at the top and stores water for humidifying the air. As shown in FIGS. 5 and 10, the water storage tank 2 is configured by a rectangular front portion taken into the housing 1 and a rear semicircular arc shape protruding rearward from the housing 1. ing. The water storage tank 2 includes a bottom portion 21 having such a planar shape, and a water storage wall 22 surrounding the periphery of the bottom portion 21.

底部２１は、後述の受水部２１ｂ及び通水溝２１ｅが形成される平面視矩形状の底面２１ａを有する。底面２１ａは、後端部から前部の途中に亘って、横方向略中央部に形成されており、貯水壁２２から適宜長離隔するような横幅を有している。底面２１ａの前方、即ち貯水槽２の前端部には略直方体の加湿フィルタ６の下部が嵌合する平面視矩形状のフィルタ嵌合凹部（貯水凹部）２１ｆが形成されている。フィルタ嵌合凹部２１ｆは、横方向両端に亘って形成されおり、底面２１ａよりも深く窪んでいる。なお、フィルタ嵌合凹部２１ｆの形状は、必ずしも加湿フィルタ６の下部が嵌合する形状である必用は無く、少なくとも、加湿フィルタ６の下部を浸す水が溜まる凹形状であれば良い。また、貯水壁２２の内側の全周に亘って底面２１ａよりも高い上段底面部２１ｇが形成されている。上段底面部２１ｇは、後述する覆体４を支持すると共に、加湿送風機が傾いた際に水が溢れにくくするための構造である。 The bottom portion 21 has a bottom surface 21a having a rectangular shape in plan view in which a water receiving portion 21b and a water flow groove 21e described later are formed. The bottom surface 21 a is formed in a substantially central portion in the lateral direction from the rear end portion to the middle of the front portion, and has a lateral width that is appropriately separated from the water storage wall 22. A filter fitting recess (water storage recess) 21f having a rectangular shape in a plan view is formed in front of the bottom surface 21a, that is, at the front end of the water storage tank 2, and the lower portion of the substantially rectangular parallelepiped humidification filter 6 is fitted. The filter fitting recess 21f is formed across the lateral ends and is deeper than the bottom surface 21a. The shape of the filter fitting recess 21f does not necessarily need to be a shape in which the lower portion of the humidifying filter 6 is fitted, and may be at least a concave shape in which water that soaks the lower portion of the humidifying filter 6 is accumulated. Moreover, the upper stage bottom face part 21g higher than the bottom face 21a is formed over the inner periphery of the water storage wall 22. The upper bottom portion 21g is a structure for supporting the cover 4 described later and preventing water from overflowing when the humidifying blower is tilted.

貯水槽２の底面２１ａの後側部分には、給水タンク３から供給された水を受ける受水部２１ｂが形成されている。給水タンク３は、図１及び図３に示すように平面視が貯水槽２と略同形の半円柱状をなすタンク本体３１と、タンク本体３１から下方へ突出した給水口３２とを有する。給水口３２はタンク本体３１に螺合しており、給水口３２を開閉させるための開閉棒３３が進退可能に設けられている。開閉棒３３は図示しない付勢手段によって閉方向に付勢されており、付勢力に抗して開閉棒３３を押し込むことによって、給水口３２が開口するように構成されている。受水部２１ｂは、給水タンク３の給水口３２の縁に倣って形成された円形の凹部である。つまり、受水部２１ｂは、給水口３２よりも一回り大きい円形の凹部である。受水部２１ｂの中心は貯水槽２の横方向略中央部に位置しており、受水部２１ｂの中央には、給水口３２を開口させるための受水棒２１ｃが上方へ突出している。貯水槽２の上部に給水タンク３が載置された場合、受水棒２１ｃによって給水口３２の開閉棒３３が開方向へ押し込まれ、給水口３２が開口する。
また、貯水槽２の底面２１ａには、受水部２１ｂと、フィルタ嵌合凹部２１ｆとを連通し、受水部２１ｂで受けた水をフィルタ嵌合凹部２１ｆへ流す通水溝２１ｅが形成されている。より具体的には、通水溝２１ｅは前後方向に長い直線状であり、貯水槽２の横方向略中央部に形成されている。また、通水溝２１ｅは、受水部２１ｂ側よりもフィルタ嵌合凹部２１ｆ側の方が深くなるように傾斜している。
更に、受水部２１ｂの周縁には、給水時に給水口３２から前記給水タンク３へ空気を導入するための空気導入凹部２１ｄが複数設けられている。例えば、図１０に示すように３つの空気導入凹部２１ｄと、通水溝２１ｅとが受水部２１ｂの周縁に等配されている。つまり、通水溝２１ｅは受水部２１ｂの前側に位置し、３つの空気導入凹部２１ｄは受水部２１ｂの横方向両側と、後側とに位置している。また、空気導入凹部２１ｄは、受水部２１ｂの中心より径方向外側の方が浅くなるように形成された傾斜底を有している。受水部２１ｂの周方向及び径方向における空気導入凹部２１ｄの幅は、通水溝２１ｅ部と同程度である。空気導入凹部２１ｄの寸法は、加湿送風機が傾いた際にも、空気を給水タンク３内へ導入することが可能であれば特に限定されない。ただし、加湿送風機の転倒時に貯水槽２から溢れる水の量を減らすために、空気導入凹部２１ｄは、空気導入可能な最小寸法で構成するのが望ましい。 A water receiving portion 21 b that receives water supplied from the water supply tank 3 is formed on the rear portion of the bottom surface 21 a of the water storage tank 2. As shown in FIGS. 1 and 3, the water supply tank 3 includes a tank body 31 having a semi-cylindrical shape that is substantially the same as the water tank 2 in plan view, and a water supply port 32 that protrudes downward from the tank body 31. The water supply port 32 is screwed into the tank body 31, and an open / close bar 33 for opening and closing the water supply port 32 is provided so as to be able to advance and retreat. The opening / closing bar 33 is biased in a closing direction by a biasing means (not shown), and the water supply port 32 is configured to open by pushing the opening / closing bar 33 against the biasing force. The water receiving portion 21 b is a circular recess formed along the edge of the water supply port 32 of the water supply tank 3. That is, the water receiving portion 21 b is a circular recess that is slightly larger than the water supply port 32. The center of the water receiving portion 21b is located at a substantially central portion in the lateral direction of the water storage tank 2, and a water receiving rod 21c for opening the water supply port 32 protrudes upward at the center of the water receiving portion 21b. When the water supply tank 3 is mounted on the upper part of the water storage tank 2, the open / close bar 33 of the water supply port 32 is pushed in the opening direction by the water receiving rod 21c, and the water supply port 32 is opened.
Further, a water passage groove 21e is formed in the bottom surface 21a of the water storage tank 2 so that the water receiving portion 21b and the filter fitting recess 21f communicate with each other and the water received by the water receiving portion 21b flows into the filter fitting recess 21f. ing. More specifically, the water flow groove 21 e is a straight line that is long in the front-rear direction, and is formed at the substantially central portion in the lateral direction of the water tank 2. Moreover, the water flow groove 21e is inclined so that the filter fitting recess 21f side is deeper than the water receiving part 21b side.
Furthermore, a plurality of air introduction recesses 21 d for introducing air from the water supply port 32 to the water supply tank 3 at the time of water supply are provided at the periphery of the water receiving portion 21 b. For example, as shown in FIG. 10, three air introduction recesses 21d and a water flow groove 21e are equally arranged on the periphery of the water receiving portion 21b. That is, the water flow groove 21e is located on the front side of the water receiving portion 21b, and the three air introduction recesses 21d are located on both lateral sides and the rear side of the water receiving portion 21b. The air introduction recess 21d has an inclined bottom formed so that the outer side in the radial direction is shallower than the center of the water receiving portion 21b. The width of the air introduction recess 21d in the circumferential direction and the radial direction of the water receiving portion 21b is approximately the same as that of the water flow groove 21e. The dimensions of the air introduction recess 21d are not particularly limited as long as the air can be introduced into the water supply tank 3 even when the humidifying blower is tilted. However, in order to reduce the amount of water that overflows from the water storage tank 2 when the humidifying blower falls, it is desirable that the air introduction recess 21d be configured with a minimum dimension capable of introducing air.

貯水壁２２は、後部を構成する平面視円弧状の後面壁２２ａと、前部を構成する側壁２２ｂ、２２ｃと、第１筐体部分１１の隔壁１１ｂに対向する対向壁２２ｄとを有する。対向壁２２ｄは、貯水槽２が隔壁１１ｂの通流孔１１ｃ側へ傾いた際に、通流孔１１ｃに対向していない対向壁２２ｄの部位から、貯留された水を外部へ漏出させる漏出部を有する。具体的には、対向壁２２ｄの上部に段状部分２２ｆが形成されて前方へ迫り出しており、平面視において隔壁１１ｂに対して斜めに対向する傾斜壁部２２ｅが対向壁２２ｄに設けられている。段状部分２２ｆは、前方の方が後方に比べて高くなるように構成されている。傾斜壁部２２ｅの横方向一端部は隔壁１１ｂに当接している。該一端部は隔壁１１ｂに当接して、貯水槽２のガタつきを抑えるための当接部として機能する。また、傾斜壁部２２ｅの前記一端部には、加湿送風機が傾いた際、貯留された水を前記貯水槽２の外へ伝わせ、効果的に漏出させるための漏出凹部２２ｇが形成されている。なお、貯水槽２の水を貯水槽２の外へ伝わせる構造は凹形状に限定されず、凸部であっても良い。 The water storage wall 22 includes a rear surface wall 22a having a circular arc shape in plan view that configures the rear portion, side walls 22b and 22c that configure the front portion, and an opposing wall 22d that faces the partition wall 11b of the first housing portion 11. The opposing wall 22d is a leakage portion that leaks stored water to the outside from the portion of the opposing wall 22d that does not face the flow hole 11c when the water storage tank 2 is tilted toward the flow hole 11c of the partition wall 11b.

Water can be smoothly supplied regardless of the inclination.

また、受水部２１ｂの周縁に空気導入凹部２１ｄが設けられているため、加湿器が傾き、通水溝２１ｅ側からの空気の導入が困難になった場合であっても、空気導入凹部２１ｄを通じて空気が給水口３２から給水タンク３内に導入され、給水を円滑に行うことができる。 Moreover, since the air introduction recessed part 21d is provided in the periphery of the water receiving part 21b, even if it is a case where the humidifier inclines and it becomes difficult to introduce the air from the water flow groove 21e side, the air introduction recessed part 21d Thus, air is introduced into the water supply tank 3 from the water supply port 32, and water can be supplied smoothly.

図１６は変形例１に係る貯水槽１０２を示す平面図である。変形例１に係る貯水槽１０２は、実施の形態と同様、底部２１及び貯水壁２２を備え、底面２１ａには受水部２１ｂが形成されている。受水部２１ｂには、２つの空気導入凹部２１ｄが、通水溝２１ｅと共に３等配されている。つまり、受水部２１ｂの周縁に、通水溝２１ｅと、２つの空気導入凹部２１ｄとが１２０度の間隔を空けて設けられている。 (Modification 1)
FIG. 16 is a plan view showing the water storage tank 102 according to the first modification. Similar to the embodiment, the water storage tank 102 according to Modification 1 includes a bottom portion 21 and a water storage wall 22, and a water receiving portion 21b is formed on the bottom surface 21a. In the water receiving portion 21b, two air introduction concave portions 21d are arranged in three parts together with the water flow groove 21e. That is, the water flow groove 21e and the two air introduction recesses 21d are provided on the periphery of the water receiving portion 21b with an interval of 120 degrees.

このように２つの空気導入凹部２１ｄを設けた加湿送風機にあっては、加湿送風機が前後左右に傾いた場合であっても、通水溝２１ｅ、２つの空気導入凹部２１ｄのいずれかから空気を導入することができ、より少数の空気導入凹部２１ｄをもって、実施の形態と同様の効果を奏することができる。 Thus, in the humidifying blower provided with the two air introduction recesses 21d, even if the humidification blower is tilted forward, backward, left and right, air is supplied from either the water flow groove 21e or the two air introduction recesses 21d. The number of air introduction recesses 21d can be reduced, and the same effect as in the embodiment can be obtained.

（変形例２）
図１７は変形例２に係る貯水槽２０２を示す平面図である。
変形例２に係る貯水槽２０２は、実施の形態と同様、底部２１及び貯水壁２２を備え、底面２１ａには受水部２１ｂが形成されている。受水部２１ｂには、円弧状の空気導入凹部２１ｄが、通水溝２１ｅと対向するように設けられている。受水部２１ｂの後側の周縁に、円弧状の空気導入凹部２１ｄが設けられている。空気導入凹部２１ｄは、受水部２１ｂを中心にして左右方向にそれぞれ略６０度、全体で１２０度の範囲に亘って形成されている。 (Modification 2)
FIG. 17 is a plan view showing a water storage tank 202 according to the second modification.
Similar to the embodiment, the water storage tank 202 according to the modified example 2 includes a bottom portion 21 and a water storage wall 22, and a water receiving portion 21b is formed on the bottom surface 21a. The water receiving portion 21b is provided with an arc-shaped air introducing recess 21d so as to face the water passage groove 21e. An arcuate air introduction recess 21d is provided on the rear edge of the water receiving portion 21b. The air introduction recess 21d is formed over a range of approximately 60 degrees in the left-right direction about the water receiving part 21b and 120 degrees in total.

このように空気導入凹部２１ｄを設けた加湿送風機にあっては、加湿送風機が前後左右に傾いた場合であっても、通水溝２１ｅ、２つの空気導入凹部２１ｄのいずれかから空気を導入することができ、より効果的に空気を導入することができ、加湿フィルタ６への給水を円滑に行うことができる。 Thus, in the humidifying blower provided with the air introduction recess 21d, air is introduced from either the water flow groove 21e or the two air introduction recesses 21d even when the humidification blower is tilted back and forth and left and right. Thus, air can be introduced more effectively, and water supply to the humidifying filter 6 can be performed smoothly.
