Description

【発明の属する技術分野】
【０００１】
本発明は、外装ケース内に設置された水槽に水を入れ、この水をヒータで加熱して蒸発させることによって加湿を行う加湿器に関するものである。
【従来の技術】
【０００２】
図２は従来の加湿器の一例を示す断面図である。
【０００３】
従来この種の加湿器９では、図２に示すように、水槽３の内面に付着した水垢などを払拭しやすくするため、広口の開口部を有する水槽３が多く用いられていた。
【発明が解決しようとする課題】
【０００４】
しかしながら、これでは、加湿器９の運転中や運転停止直後に水槽３内の水量を確認すべく天蓋７を開けた場合、水槽３内の水が高温になっているため、水槽３の広口の開口部全面から高温の水蒸気が立ちのぼり、天蓋７の下面を伝って上昇し、天蓋７を持った手に高温の水蒸気が触れて火傷をする危険性があった。
【０００５】
本発明は、上記事情に鑑み、運転中などに天蓋を開けても高温の水蒸気で火傷をすることのない安全な加湿器を提供することを目的とする。
【課題を解決するための手段】
【０００６】
すなわち本発明は、外装ケースを有し、この外装ケース内に広口の開口部を有する水槽を設け、この水槽にヒータを当該水槽内の水を加熱し得る形で設け、前記外装ケースに天蓋を前記水槽の開口部を覆う形で開閉自在に設け、この天蓋に前記水槽で発生する加湿用水蒸気の吹出口を形成した加湿器において、中央に一つの排気孔が形成された円盤状の蒸気調整板を、前記水槽の開口部を覆う形で前記天蓋とは別に着脱自在に設け、前記蒸気調整板の排気孔に沿って、円環状のリブを当該リブの上端が全閉状態の前記天蓋の下面に当接する形で上向きに設けて構成される。
【発明の実施の形態】
【０００７】
以下、本発明の実施形態を図１の図面に基づいて説明する。
【０００８】
図１は本発明による加湿器の実施形態を示す断面図である。
【０００９】
本発明による加湿器９は、図１に示すように、円筒状の外装ケース１を有しており、外装ケース１内には円筒状の内側ケース５が挿設されている。内側ケース５の底部にはヒータ２が設置されており、ヒータ２の上側には広口の開口部を有する円筒状の水槽３が着脱自在に載置されている。
【００１０】
前記水槽３の上部の開口部には、円盤状の蒸気調整板４が水槽３の開口部を覆う形で、しかも、後述する天蓋７とは別に着脱自在に載置されている。前記蒸気調整板４の中央には円形の排気孔４ａが形成されていると共に、この排気孔４ａに沿って、円環状のリブ４ｂを当該リブ４ｂの上端が全閉状態の前記天蓋７の下面に当接するように上向きに形成している。さらに蒸気調整板４には、つまみ４ｃが取り付けられている。
【００１１】
また、外装ケース１の上部には天蓋７が蒸気調整板４を覆う形で開閉自在に取り付けられており、天蓋７の中央には加湿用水蒸気を吹出すための吹出口７ａが形成されている。
【００１２】
本発明による加湿器９は以上のような構成を有するので、この加湿器９を運転する際には、まず水槽３に水を入れる。この際、蒸気調整板４は、天蓋７とは独立した形で水槽７の開口部に着脱自在としてあるので、蒸気調整板４をそのつまみ４ｃを持って取り除き、その状態で注水作業を円滑に行うことができる。次いで、ヒータ２に通電する。すると、水槽３内の水がヒータ２によって加熱されて水蒸気となる。こうして発生した水蒸気は、蒸気調整板４の排気孔４ａを通って天蓋７の吹出口７ａから排出され、加湿器９付近が加湿される。
【００１３】
ところで、加湿器９の運転中や運転停止直後に水槽３内の水量を確認すべく天蓋７を開けた場合、水槽３内の水が高温になっているため、水槽３の広口の開口部全面から高温の水蒸気が立ちのぼろうとするが、水槽３の開口部を覆う形で蒸気調整板４が載置されているので、加湿運転中に発生する水蒸気は蒸気調整板４の排気孔４ａに集められ、円環状のリブ４ｂで案内されて、天蓋７内に入ることになる。従って、水槽３内で発生した水蒸気がまっすぐ天蓋７の吹出口７ａに誘導されるので、天蓋７の下面や蒸気調整板４の上面が必要以上に濡れることがない。そして、天蓋７を持った手の方には水蒸気が殆ど流れてこない。その結果、高温の水蒸気で火傷をする事態の発生を未然に防止することができ、安全性に優れると共に、水槽３内で発生した水蒸気をまっすぐ天蓋７の吹出口７ａに誘導することができることから、天蓋７の下面や蒸気調整板４の上面が必要以上に濡れる事態の発生を回避することができる。
【００１４】
また、蒸気調整板４の排気孔４ａは水槽３の内部が見える程度の大きさとなっているので、蒸気調整板４を取り除かなくても水槽３内の様子、すなわち水量や汚れ具合を容易に確かめることができる。
【発明の効果】
【００１５】
以上説明したように本発明によれば、外装ケースを有し、この外装ケース内に広口の開口部を有する加湿用の水槽を設け、この水槽にヒータを当該水槽内の水を加熱し得る形で設け、前記外装ケースに天蓋を前記水槽の開口部を覆う形で開閉自在に設け、この天蓋に前記水槽で発生する加湿用の水蒸気の吹出口を形成した加湿器において、中央に一つの排気孔が形成された円盤状の蒸気調整板を、前記水槽の開口部を覆う形で前記天蓋とは別に着脱自在に設け、前記蒸気調整板の排気孔に沿って、円環状のリブを当該リブの上端が全閉状態の前記天蓋の下面に当接する形で上向きに設けて構成したので、天蓋を開けたときに立ちのぼる水蒸気が蒸気調整板の排気孔のみに集中することから、加湿器の運転中などに天蓋を開けても高温の水蒸気で火傷をすることがない点で安全性に優れると共に、水槽内で発生した水蒸気をまっすぐ天蓋の吹出口に誘導することができることから、天蓋の下面や蒸気調整板の上面が必要以上に濡れる事態の発生を回避することが可能となる。

[0001]
TECHNICAL FIELD The present invention relates to a humidifier that humidifies water by putting water into a water tank installed in an outer case and heating the water with a heater to evaporate the water.
[Prior art]
[0002]
FIG. 2 is a sectional view showing an example of a conventional humidifier.
[0003]
Conventionally, in this type of humidifier 9, as shown in FIG. 2, a water tank 3 having a wide-opening is often used in order to easily wipe water scale or the like attached to the inner surface of the water tank 3.
[Problems to be solved by the invention]
[0004]
However, in this case, when the canopy 7 is opened to check the amount of water in the water tank 3 during or immediately after the operation of the humidifier 9, the temperature of the water in the water tank 3 is high. There was a risk that high-temperature steam would rise from the entire surface of the opening, rise along the lower surface of the canopy 7, and be injured when the high-temperature steam touches the hand holding the canopy 7.
[0005]
In view of the above circumstances, an object of the present invention is to provide a safe humidifier that does not cause burns due to high-temperature steam even when the canopy is opened during driving or the like.
[Means for Solving the Problems]
[0006]
That is, the present invention has an outer case, a water tank having a wide opening is provided in the outer case, a heater is provided in the water tank in a form capable of heating water in the water tank, and a canopy is provided in the outer case. In a humidifier having an openable and closable cover for covering the opening of the water tank and an outlet for humidifying steam generated in the water tank formed in the canopy, a disk-shaped steam control having one exhaust hole formed in the center. A plate is provided detachably separately from the canopy so as to cover the opening of the water tank, and along the exhaust hole of the steam adjusting plate, an annular rib is provided on the top of the canopy with its upper end fully closed. It is configured to be provided upwardly in contact with the lower surface.
BEST MODE FOR CARRYING OUT THE INVENTION
[0007]
Hereinafter, an embodiment of the present invention will be described with reference to the drawing of FIG.
[0008]
FIG. 1 is a sectional view showing an embodiment of a humidifier according to the present invention.
[0009]
A humidifier 9 according to the present invention has a cylindrical outer case 1 as shown in FIG. 1, and a cylindrical inner case 5 is inserted into the outer case 1. A heater 2 is provided at the bottom of the inner case 5, and a cylindrical water tank 3 having a wide opening is removably mounted above the heater 2.
[0010]
A disc-shaped steam adjusting plate 4 is placed in the upper opening of the water tank 3 so as to cover the opening of the water tank 3 and is detachably mounted separately from a canopy 7 described later. A circular exhaust hole 4a is formed at the center of the steam adjusting plate 4, and an annular rib 4b is formed along the exhaust hole 4a on the lower surface of the canopy 7 in which the upper end of the rib 4b is fully closed. It is formed upward so as to abut against. Further, a knob 4c is attached to the steam adjusting plate 4.
[0011]
A canopy 7 is attached to the upper part of the outer case 1 so as to be openable and closable so as to cover the steam adjusting plate 4, and an outlet 7 a for blowing out humidifying steam is formed in the center of the canopy 7. .
[0012]
Since the humidifier 9 according to the present invention has the above configuration, when the humidifier 9 is operated, first, water is put into the water tank 3. At this time, since the steam adjusting plate 4 is detachable from the opening of the water tank 7 independently of the canopy 7, the steam adjusting plate 4 is removed by holding the knob 4c, and the water injection work is smoothly performed in that state. It can be carried out. Next, the heater 2 is energized. Then, the water in the water tank 3 is heated by the heater 2 to become steam. The water vapor generated in this way is discharged from the outlet 7a of the canopy 7 through the exhaust hole 4a of the steam adjusting plate 4, and the vicinity of the humidifier 9 is humidified.
[0013]
By the way, when the canopy 7 is opened to check the amount of water in the water tank 3 during or immediately after the operation of the humidifier 9, since the water in the water tank 3 is hot, the entire wide opening of the water tank 3 is opened. However, since the steam adjusting plate 4 is placed so as to cover the opening of the water tank 3, the steam generated during the humidifying operation is supplied to the exhaust hole 4 a of the steam adjusting plate 4. They are collected, guided by the annular ribs 4b, and enter the canopy 7. Accordingly, since the steam generated in the water tank 3 is guided straight to the outlet 7a of the canopy 7, the lower surface of the canopy 7 and the upper surface of the steam adjusting plate 4 are not wetted more than necessary. Water vapor hardly flows toward the hand holding the canopy 7. As a result, it is possible to prevent the occurrence of a situation in which a burn is caused by high-temperature steam, and it is possible to excel in safety and to guide the steam generated in the water tank 3 straight to the outlet 7a of the canopy 7. In addition, it is possible to prevent the lower surface of the canopy 7 and the upper surface of the steam adjusting plate 4 from getting wet more than necessary.
[0014]
Further, since the exhaust hole 4a of the steam adjusting plate 4 is so large that the inside of the water tank 3 can be seen, the state inside the water tank 3 without removing the steam adjusting plate 4, that is, the amount of water and the degree of contamination can be easily checked. be able to.
【The invention's effect】
[0015]
As described above, according to the present invention, the outer case is provided, and a water tank for humidification having a wide opening is provided in the outer case, and a heater is provided in the water tank to heat water in the water tank. In the humidifier having a canopy provided in the outer case so as to be openable and closable so as to cover the opening of the water tank, and an outlet for water vapor for humidification generated in the water tank formed in the canopy, one exhaust is provided at the center. A disc-shaped steam adjusting plate having a hole formed thereon is detachably provided separately from the canopy so as to cover the opening of the water tank, and an annular rib is provided along the exhaust hole of the steam adjusting plate. The upper end of the humidifier is provided upward so as to contact the lower surface of the canopy in a fully closed state. High temperature steam even if the canopy is opened inside It is excellent in safety because it does not cause burns, and because the water vapor generated in the water tank can be guided straight to the outlet of the canopy, the lower surface of the canopy and the upper surface of the steam adjustment plate may get wet more than necessary. It is possible to avoid occurrence.
