Description

本発明は、加熱により水を蒸気化する加湿器に係り、より詳しくは、蒸発皿や蒸発筒と接触する吸水フィルターに対する接触圧を均一に保つことで安定した加湿量を得ることができる加湿器に関するものである。 The present invention relates to a humidifier that vaporizes water by heating, and more specifically, a humidifier that can obtain a stable humidification amount by maintaining a uniform contact pressure with respect to a water absorption filter that contacts an evaporating dish or an evaporation cylinder. It is about.

従来の加熱式の加湿器においては、吸水フィルターを保持する場合これをリング等で固定したり、あるいは吸水フィルターの密着性を向上させるためにゴム製やバネ製のフックバンドで端部を引張るようにして留めるなどして、吸水フィルターを外側から保持する構成になっていた（例えば、特許文献１参照）。 In conventional heating humidifiers, when holding the water absorption filter, fix it with a ring, etc., or pull the end with a rubber or spring hook band to improve the adhesion of the water absorption filter. The water absorption filter is configured to be retained from the outside by, for example, fastening (see, for example, Patent Document 1).

特開平１０−２６３７９号公報（第６頁、図１−図２）Japanese Patent Laid-Open No. 10-26379 (6th page, FIGS. 1-2)

従来のようにして吸水フィルターを保持する場合は、一部分にバネ性を有するだけであるため接触圧に偏りが生じ、さらにバネ性を失った場合には接触面が離れてしまうおそれがあった。また、吸水フィルターの内側では加熱ブロックと接触させて保持することができるが、吸水フィルターの外側では均等に接触することができないという不具合があった。 When the water absorption filter is held as in the prior art, the contact pressure is biased because only a part has the spring property, and when the spring property is lost, the contact surface may be separated. Moreover, although it can be made to contact and hold with a heating block inside a water absorption filter, there existed a malfunction that it could not contact uniformly on the outer side of a water absorption filter.

本発明は上記の課題を解決するためになされたもので、加湿器の構成に合せて、吸水フィルターをその内側及び外側のどちらからでも保持することができる保持体によって、吸水フィルターと蒸発皿または蒸発筒との接触圧を常に均等に保持して、安定した加湿量を得ることができる加湿器を提供することを目的とする。 The present invention has been made in order to solve the above-described problems. According to the configuration of the humidifier, the water absorption filter and the evaporating dish or the evaporating dish or the water absorption filter can be held by a holding body that can hold the water absorption filter from either the inside or the outside. An object of the present invention is to provide a humidifier capable of always maintaining a uniform contact pressure with the evaporation cylinder and obtaining a stable humidification amount.

本発明に係る加湿器は、加湿器の本体と、本体に接合され下部に水を貯留する蒸発皿と、蒸発皿に水を供給する給水路と、蒸発皿の外壁を加熱する加熱体と、線材を上下方向に交互にほぼＵ字状に折り返しその端点を接合してほぼ円筒形状に形成した内外に伸縮可能なバネ性を有する保持体と、内接する保持体によって蒸発皿の内壁に均等な接触圧で接触し毛細管現象によって蒸発皿内の水を吸上げるほぼ円筒形状に形成した吸水フィルターとを備えたものである。 The humidifier according to the present invention includes a main body of the humidifier, an evaporating dish that is joined to the main body and stores water in a lower part, a water supply path that supplies water to the evaporating dish, a heating body that heats the outer wall of the evaporating dish, The wire rod is folded up and down alternately in a substantially U shape, and its end points are joined together to form a substantially cylindrical shape. It is provided with a water absorption filter formed in a substantially cylindrical shape that makes contact with the contact pressure and sucks up water in the evaporating dish by capillary action.

保持体のどの部分においても吸水フィルターを蒸発皿に押し付ける力が働き、多方向にバネ性があることから局部に集中している過荷重が分散され、接触圧が均等化されるので、安定した熱伝導による安定した加湿が得られる。 The force that pushes the water absorption filter against the evaporating dish works in any part of the holding body, and since there is springiness in multiple directions, the overload concentrated in the local area is dispersed and the contact pressure is equalized, so it is stable Stable humidification by heat conduction is obtained.

実施の形態１．
図１は本発明の実施の形態１に係る加湿器の蒸発部を示す縦断面図である。図１に示すように、蒸発皿２はパッキン３を介して本体１に接合されている。蒸発皿２にはその内部に水を供給する給水路４が設けられ、蒸発皿２の外壁には外壁部を加熱する加熱体５が設けられている。蒸発皿２の内側には蒸発皿２の内壁に接するように円筒状の吸水フィルター６が配設され、吸水フィルター６の下部は水１０に浸されて毛細管により水を吸上げるようになっている。吸水フィルター６の内側には吸水フィルター６の内壁に沿って保持体７が配設されている。この保持体７は、その外側に巻付けられた吸水フィルター６を蒸発皿２の内壁に均等な荷重で密接させるバネ性を持ち、吸水フィルター６に対して任意に着脱可能である。 Embodiment 1 FIG.
FIG. 1 is a longitudinal sectional view showing an evaporation section of a humidifier according to Embodiment 1 of the present invention. As shown in FIG. 1, the evaporating dish 2 is joined to the main body 1 via a packing 3. The evaporating dish 2 is provided with a water supply path 4 for supplying water therein, and an outer wall of the evaporating dish 2 is provided with a heating body 5 for heating the outer wall portion. A cylindrical water absorption filter 6 is disposed inside the evaporating dish 2 so as to be in contact with the inner wall of the evaporating dish 2, and the lower part of the water absorbing filter 6 is immersed in water 10 to suck up water by a capillary tube. . A holding body 7 is disposed along the inner wall of the water absorption filter 6 inside the water absorption filter 6. The holding body 7 has a spring property that allows the water absorption filter 6 wound around the outside thereof to come into close contact with the inner wall of the evaporating dish 2 with an equal load, and can be arbitrarily attached to and detached from the water absorption filter 6.

図２は図１に示した加湿器の保持体７の斜視図であり、図３は図２に示した保持体７の動作を示す説明図である。図２に示すように、保持体７は、耐熱性、耐熱水性、耐薬品性、耐錆性に優れた例えばステンレスよりなるバネ材で、断面が円形の線材によって形成されている。そして、この線材を交互にＵ字状に折り返したもので、端点を溶接等によって接合して円筒形状に形成しており、どこにも支点を持たないようになっている。このため、図３に示すように、１本当たりのＵ字状部分７ａに荷重を受けても他のＵ字状部分には大きく影響を与えず、許容値を超えた大きな荷重を受けた場合は、連鎖しているため荷重を分散することができる。 2 is a perspective view of the holding body 7 of the humidifier shown in FIG. 1, and FIG. 3 is an explanatory view showing the operation of the holding body 7 shown in FIG. As shown in FIG. 2, the holding body 7 is a spring material made of, for example, stainless steel having excellent heat resistance, hot water resistance, chemical resistance, and rust resistance, and is formed of a wire having a circular cross section. The wire is alternately folded back into a U shape, and the end points are joined by welding or the like to form a cylindrical shape, so that no fulcrum is provided anywhere. For this reason, as shown in FIG. 3, even when a load is applied to one U-shaped portion 7a, the other U-shaped portions are not significantly affected and a large load exceeding the allowable value is received. Can disperse the load because they are chained.

このように、保持体７は、内、外、上、下、左、右のいずれの方向にもバネ性を持っており、取付け時は、保持体７の外側に吸水フィルター６を巻き付け、内側方向に撓ませることによって容易に蒸発皿２内に収めることができ、外側方向に復元しようとするバネ性により、吸水フィルター６を蒸発皿２の内壁に均等に密接することができる。取り外し時は、吸水フィルター６と保持体７を一緒に内側方向に撓ませることで、蒸発皿２の内壁より吸水フィルター６を引き剥がすことができ、または、吸水フィルター６と保持体７の一部分を掴んで上に引き上げることによって蒸発皿２内から取り外しすることができる。取り外した後の保持体７は、そのバネ性によって、元の形状に復元する。 As described above, the holding body 7 has spring properties in any of the inner, outer, upper, lower, left, and right directions, and the water absorbing filter 6 is wound around the outer side of the holding body 7 at the time of mounting. The water absorption filter 6 can be evenly brought into close contact with the inner wall of the evaporating dish 2 by being bent in the direction and easily accommodated in the evaporating dish 2 and by the spring property to be restored in the outer direction. At the time of removal, the water absorption filter 6 and the holding body 7 can be bent inward together so that the water absorption filter 6 can be peeled off from the inner wall of the evaporating dish 2 or a part of the water absorption filter 6 and the holding body 7 can be removed. It can be removed from the evaporating dish 2 by grasping and pulling up. The removed holding body 7 is restored to its original shape by its spring property.

次に、動作について説明する。図１に示すように、給水路４より流入した水は蒸発皿２の下部より蒸発皿２内に供給され、蒸発皿２内の水位は一定の高さに保たれる。このとき、保持体７の外壁に巻き付けられた吸水フィルター６は蒸発皿２の内壁に接するように取付けられ、保持体７のバネ性による均等な接触圧によって蒸発皿２の内壁に押し付けられている。吸水フィルター６は、自身の毛細管現象によってその上端まで水を吸上げ、蒸発皿２を介して加熱体５により加熱され、蒸気を発生させて外部に噴霧される。 Next, the operation will be described. As shown in FIG. 1, the water flowing in from the water supply channel 4 is supplied into the evaporating dish 2 from the lower part of the evaporating dish 2, and the water level in the evaporating dish 2 is kept at a constant height. At this time, the water absorption filter 6 wound around the outer wall of the holding body 7 is attached so as to be in contact with the inner wall of the evaporating dish 2 and is pressed against the inner wall of the evaporating dish 2 by an equal contact pressure due to the spring property of the holding body 7. . The water absorption filter 6 sucks water up to its upper end by its own capillary phenomenon, is heated by the heating body 5 through the evaporating dish 2, generates steam, and is sprayed to the outside.

本実施の形態１によれば、保持体７は、線材を交互にＵ字状に折り返し、端点を溶接等によって接合して円筒形状に形成されており、内、外、上、下、左、右のいずれの方向にもバネ性を持っているので、蒸発皿２と吸水フィルター６との接触を均等化することができ、このため吸水フィルター６への熱伝導が安定し、それによって安定した加湿を行うことができる。また、保持体７が支点を持たない形状のため、着脱時等に大きな応力を受けても、変形等の影響を最小限に抑えることができる。さらに、ステンレスのバネ材により、錆や腐食や熱変形の影響を受けずに使用することができる。また、断面形状が円の線材であるから、蒸発皿６の表面に傷が付着するのを防止することができる。 According to the first embodiment, the holding body 7 is formed in a cylindrical shape by alternately folding the wire rods in a U shape and joining the end points by welding or the like, and the inner, outer, upper, lower, left, Since it has a spring property in any direction on the right, it is possible to equalize the contact between the evaporating dish 2 and the water absorption filter 6, and thus the heat conduction to the water absorption filter 6 is stabilized and thereby stable. Humidification can be performed. Moreover, since the holding body 7 has a shape that does not have a fulcrum, the influence of deformation or the like can be minimized even if a large stress is applied during attachment or detachment. Further, the stainless spring material can be used without being affected by rust, corrosion or thermal deformation. Further, since the cross-sectional shape is a circular wire, it is possible to prevent scratches from adhering to the surface of the evaporating dish 6.

実施の形態２．
図４は本発明の実施の形態２に係る加湿器の蒸発部を示す縦断面図である。図に示すように、加湿器の本体１の円筒状の吸水フィルター６が配設され、吸水フィルター６の下部は水１０に浸されて毛細管により水を吸上げるようになっている。吸水フィルター６の外側には保持体７が位置して吸水フィルター６の外壁が保持体７と均等に接触し、一方、吸水フィルター６の内壁に沿って凸形の蒸発筒２０が収納されている。こうして、吸水フィルター６の取付け時に、吸水フィルター６によって外周方向に広げられた保持体７は、元の形状に復元しようとするバネ性によって、吸水フィルター６を蒸発筒２０側に均等に密接させる。吸水フィルター６の取外し時には、保持体７を外側方向に広げて先に外すことで、容易に作業することができる。
このように、吸水フィルター６を保持体７の内側に位置させ、保持体７の内壁に蒸発筒２０を密接させるようにしても、実施の形態１と同様の効果を得ることができる。 Embodiment 2. FIG.
FIG. 4 is a longitudinal cross-sectional view showing the evaporation section of the humidifier according to Embodiment 2 of the present invention. As shown in the figure, a cylindrical water absorption filter 6 of the main body 1 of the humidifier is disposed, and a lower portion of the water absorption filter 6 is immersed in water 10 to suck up water by a capillary tube. A holding body 7 is located outside the water absorption filter 6, and the outer wall of the water absorption filter 6 contacts the holding body 7 evenly. On the other hand, a convex evaporation cylinder 20 is accommodated along the inner wall of the water absorption filter 6. . Thus, when the water absorption filter 6 is attached, the holding body 7 expanded in the outer peripheral direction by the water absorption filter 6 causes the water absorption filter 6 to be evenly in close contact with the evaporation cylinder 20 side by the spring property to restore the original shape. When removing the water absorption filter 6, it is possible to easily work by spreading the holding body 7 outward and removing it first.
Thus, even if the water absorption filter 6 is positioned inside the holding body 7 and the evaporation cylinder 20 is brought into close contact with the inner wall of the holding body 7, the same effect as in the first embodiment can be obtained.
