Description

本発明は、加熱により水を蒸気化する加熱式加湿器に関するものである。   The present invention relates to a heating humidifier that evaporates water by heating.

従来の加熱式加湿器においては、送風機構を設けることで、蒸気出口から放出される蒸気温度を60℃程度とし、また、本体転倒時の熱湯流出での火傷安全策として、吸水部材の毛細管作用により吸い上げた少量の水のみを上部に設けた加熱体により加熱して加湿することで、必要以上の熱湯を持たない構成となっている。(例えば、特許文献1参照)   In the conventional heating type humidifier, the steam temperature discharged from the steam outlet is set to about 60 ° C. by providing a blower mechanism, and the capillary action of the water absorbing member is used as a safety measure for burns when hot water flows out when the main body falls. Only a small amount of water sucked up by the above is heated and humidified by a heating body provided on the upper part, so that it does not have more hot water than necessary. (For example, see Patent Document 1)

特許第3434049号公報(第18頁、図1−図2)Japanese Patent No. 3434049 (page 18, FIGS. 1-2)

しかしながら、上記従来の吸水部材を持つ加湿器の場合でも、60℃の蒸気では約5秒連続接触すると、火傷を生じる危険性があるため、吹き出し蒸気や転倒時に水槽内から流出する湯に連続接触すると、火傷をする心配がった(55℃なら20秒、50℃なら3分、45℃なら1時間接触で火傷する)。また、必要以上の熱湯を持たない構成のため、吸水部材の加熱されない部分(吸い上げ下部)の温度が雑菌の繁殖しやすい温度(30〜40℃)になり、異臭が発生して衛生面でやや問題点があった。   However, even in the case of the conventional humidifier having a water absorbing member, there is a risk of causing burns when continuously contacting with steam at 60 ° C. for about 5 seconds. Then, I was worried about burns (20 seconds at 55 ° C, 3 minutes at 50 ° C, and 1 hour at 45 ° C). In addition, because it does not have more hot water than necessary, the temperature of the unheated part of the water-absorbing member (lower part of the sucked-up portion) becomes a temperature (30-40 ° C) at which various germs are easy to propagate, and a strange odor is generated and somewhat sanitary. There was a problem.

本発明は、上記問題点を解消するためになされたもので、吹き出し蒸気や転倒時に水槽内から流出する湯に連続接触しても火傷の心配がなく、かつ衛生性を兼ね備えた加熱式加湿器を提供することを目的としている。   The present invention has been made to solve the above problems, and there is no fear of burns even when continuously in contact with blown steam or hot water flowing out of the water tank at the time of overturning, and a heating humidifier having hygiene The purpose is to provide.

次に、上記の構成からなる実施の形態1の加熱式加湿器の動作について説明する。
まず、水タンク2を本体1にセットすると、水タンク2内の水はタンクキャップ3に備えられている落水口4を通って水受部5に供給されタンクキャップ3により一定水位に保持される。水受部5の水は水槽6に供給され、水槽6内の水位は水受部5と同水位で、水槽6底面より10〜20mmの高さに保持される。
水槽6内壁に接するように設けられた吸水部材7は自身の毛細管現象により上端まで水を吸上げ、水槽6を介して加熱体8により加熱され蒸気を発生させる。水槽6はアルミニウムで形成されており、熱伝導の良さから吸水部材7を加熱する際の余熱が水槽6底面まで伝搬されるので、吸水部材7下部を浸している水は50〜70℃まで加熱され殺菌される。
Next, the operation of the heating humidifier of the first embodiment configured as described above will be described.
First, when the water tank 2 is set in the main body 1, the water in the water tank 2 is supplied to the water receiving portion 5 through the water outlet 4 provided in the tank cap 3 and is held at a constant water level by the tank cap 3. . The water in the water receiving section 5 is supplied to the water tank 6, and the water level in the water tank 6 is the same as that of the water receiving section 5 and is maintained at a height of 10 to 20 mm from the bottom surface of the water tank 6.
The water absorbing member 7 provided so as to be in contact with the inner wall of the water tank 6 sucks water up to the upper end by its capillary phenomenon and is heated by the heating body 8 through the water tank 6 to generate steam. The water tank 6 is made of aluminum, and the remaining heat when heating the water absorbing member 7 is propagated to the bottom surface of the water tank 6 due to good heat conduction, so the water immersed in the lower part of the water absorbing member 7 is heated to 50 to 70 ° C. And sterilized.

送風ファン11により吸気口10から取り込まれた空気は、本体1内に設けられて第1の風路27と第2の風路28に分配されて送風される。第1の風路27に送風された空気は蒸気案内筒9に設けられた送風取入口12と送風取入別口12Aに分配され、送風取入口12に分配された送風の一部は送風筒13により水槽6底面に向け下方向に矯正され、吸水部材7で発生した蒸気と混合して蒸気温度を40℃以下に低減させる。水槽6領域にて混合された冷却蒸気はUターンし、蒸気案内筒9に戻される。
分配された残りの空気は、送風取入別口12Aを経由して放熱部材17を通過して上方向に上ってくる冷却蒸気に対して直角方向の流れで混合するように吹き出され、撹拌するので、蒸気温度を均一に低減する。40℃以下に均一に冷却された蒸気は、吹き出し角度を45度以下に設けられた蒸気吹出口15より外部に吹き出される。その際に、前記第2の風路28を通過してきた室温と同等の空気が上方の送風吹出口16より同時に吹き出されることによって蒸気が室温との温度差により室内上空へと昇ろうとするのが抑制されるため、蒸気が天井付近にスポット的に固まることが無く、遠くまで蒸気が到達し、室内を均一に加湿する。
The air taken in from the air inlet 10 by the blower fan 11 is provided in the main body 1 and is distributed to the first air passage 27 and the second air passage 28 to be blown. The air blown to the first air passage 27 is distributed to the air intake 12 provided in the steam guide tube 9 and the air intake separate port 12A, and a part of the air distributed to the air intake 12 is an air tube. 13 is corrected downward toward the bottom of the water tank 6 and mixed with the steam generated in the water absorbing member 7 to reduce the steam temperature to 40 ° C. or lower. The cooling steam mixed in the water tank 6 region makes a U-turn and is returned to the steam guide tube 9.
The remaining air that has been distributed is blown out so as to be mixed in a flow in a direction perpendicular to the cooling steam that passes through the heat radiation member 17 through the ventilation intake port 12A and rises upward. Therefore, the steam temperature is reduced uniformly. The steam uniformly cooled to 40 ° C. or less is blown out through a steam outlet 15 provided with a blowing angle of 45 degrees or less. At that time, air equivalent to room temperature that has passed through the second air passage 28 is simultaneously blown out from the upper blower outlet 16 so that the steam rises into the indoor sky due to a temperature difference from the room temperature. Therefore, the steam does not solidify in the vicinity of the ceiling, the steam reaches far, and the room is uniformly humidified.

一方、例えば、運転状態の本体1を転倒したような場合、水槽6内の湯は蒸気案内筒9に流れ込み、放熱部材17と接触する。放熱部材17は前記送風取入別口12Aからの送風により室温と同等温度になっているので、水槽6内からこぼれて流入してきた70℃の湯と熱交換し、湯の温度を40℃以下に低減させる。   On the other hand, for example, when the main body 1 in an operating state is overturned, the hot water in the water tank 6 flows into the steam guide tube 9 and contacts the heat radiating member 17. Since the heat radiating member 17 has a temperature equal to the room temperature due to the air blown from the air blowing inlet 12A, it exchanges heat with the 70 ° C. hot water spilled from the water tank 6 and the hot water temperature is 40 ° C. or lower. To reduce.

次に、上記実施の形態1における加熱式加湿器の制御動作について、図4のフローチャートを用いて詳細に説明する。
図4に示すように、まず、ステップS1により運転スイッチ20がオンされると、ステップS2に移行する。ステップS2では、制御部18から加熱体8とタイマー手段22をオンさせる信号が出力されて、加熱体8とタイマー手段22を作動させ、ステップS3に移行する。
ステップS3では、吸気口10の近傍に設けられた室温センサ21により室温T1を測定して制御部18に出力され、ステップS4に移行する。ステップS4では、ステップS3で測定した室温T1が10℃未満の場合、遅れ時間Rを7minと決定する。室温T1が10℃以上20℃未満を超えている場合、遅れ時間Rを6minと決定する。室温T1が20℃以上の場合、遅れ時間Rを5minと決定し、ステップS5に移行する。ステップS5では、タイマー手段22でのカウント時間m1を測定して制御部18に出力し、ステップS6に移行する。
Next, the control operation of the heating humidifier in the first embodiment will be described in detail with reference to the flowchart of FIG.
As shown in FIG. 4, first, when the operation switch 20 is turned on in step S1, the process proceeds to step S2. In step S2, a signal for turning on the heating body 8 and the timer means 22 is output from the control unit 18, the heating body 8 and the timer means 22 are operated, and the process proceeds to step S3.
In step S3, the room temperature T1 is measured by the room temperature sensor 21 provided in the vicinity of the air inlet 10, and the room temperature T1 is output to the control unit 18, and the process proceeds to step S4. In step S4, when the room temperature T1 measured in step S3 is less than 10 ° C., the delay time R is determined to be 7 min. When the room temperature T1 exceeds 10 ° C. or more and less than 20 ° C., the delay time R is determined to be 6 min. When the room temperature T1 is 20 ° C. or higher, the delay time R is determined to be 5 minutes, and the process proceeds to step S5. In step S5, the count time m1 in the timer means 22 is measured and output to the control unit 18, and the process proceeds to step S6.

ステップS6では、ステップS5で測定した時間m1がステップS4で決定したR値に対して小さい場合は、ステップS5に戻り、再度時間m1を測定する。時間m1がR値よりも大きい場合は、次のステップS7に移行する。ステップS7では、制御部18より送風ファン11をオンさせる信号が出力されて送風ファン11を作動させ、加湿運転を開始する。   In step S6, when the time m1 measured in step S5 is smaller than the R value determined in step S4, the process returns to step S5 and the time m1 is measured again. When the time m1 is larger than the R value, the process proceeds to the next step S7. In step S <b> 7, a signal for turning on the blower fan 11 is output from the control unit 18 to actuate the blower fan 11 and start the humidifying operation.

次に、ステップS8では、蒸気吹出口15から吹き出される蒸気温度T2を蒸気温度センサ23で測定し、その測定結果を制御部18に対して出力する。ステップS9では、ステップS8で測定した蒸気温度T2が50℃未満なら、安全温度で加湿していると判定してステップS8に戻り、再度蒸気温度サーミスタ23にて蒸気温度T2を測定する。ステップS8で測定した蒸気温度T2が50℃以上になった場合は、蒸気温度T2が危険温度であると判定してステップS10へ移行する。   Next, in step S <b> 8, the steam temperature T <b> 2 blown from the steam outlet 15 is measured by the steam temperature sensor 23, and the measurement result is output to the control unit 18. In step S9, if the steam temperature T2 measured in step S8 is less than 50 ° C., it is determined that humidification is performed at a safe temperature, the process returns to step S8, and the steam temperature thermistor 23 measures the steam temperature T2 again. When the steam temperature T2 measured in step S8 is 50 ° C. or higher, it is determined that the steam temperature T2 is a dangerous temperature, and the process proceeds to step S10.

ステップS10では、制御部18から加熱体8をオフする信号が出力され、加熱体8への通電を停止してステップS11へ移行する。ステップS11では、制御部18から送風ファン11をオフする信号が出力され、送風ファン11への通電を停止して加湿運転を終了させ、ステップS12へ移行する。ステップS12では、清掃喚起ランプ26を点灯させて、使用者に吸水部材7の清掃を行うように喚起する。   In step S10, a signal for turning off the heating element 8 is output from the control unit 18, the energization of the heating element 8 is stopped, and the process proceeds to step S11. In step S11, a signal for turning off the blower fan 11 is output from the control unit 18, the energization to the blower fan 11 is stopped to end the humidification operation, and the process proceeds to step S12. In step S12, the cleaning alert lamp 26 is turned on to alert the user to clean the water absorbing member 7.

図5は上記の構成からなる実施の形態1の加熱式加湿器の転倒時を示す図である。
図5に示すように、加湿器が転倒した際は、水槽6内の湯は必ず蒸気案内筒9に流れ込むようになっており、その結果、蒸気案内筒9内周に設けられた放熱部材17と接触する。放熱部材17は送風により室温程度に常時冷却されているため、放熱部材17に接触した70℃の湯は50℃未満までに温度が低減され、一部が外部へ流出することになる。
FIG. 5 is a diagram illustrating the overturning of the heating humidifier according to the first embodiment having the above-described configuration.
As shown in FIG. 5, when the humidifier falls, the hot water in the water tub 6 always flows into the steam guide tube 9, and as a result, the heat dissipating member 17 provided on the inner periphery of the steam guide tube 9. Contact with. Since the heat dissipating member 17 is constantly cooled to about room temperature by blowing air, the temperature of the 70 ° C. hot water contacting the heat dissipating member 17 is reduced to less than 50 ° C., and a part flows out to the outside.

以上のように、上記実施の形態1によれば、水槽6底面に向けて下方向に送風を供給する送風筒13と横方向に風を取り入れる送風取入別口12Aとを設けたことで、蒸気温度をムラ無く40℃以下にすることができる。また、蒸気案内筒9の上部内周に常に送風が通過して冷却されている放熱部材17を設けたことで、加湿器が転倒した時に、水槽6内から流出するお湯が放熱部材17と接触し、50℃以下に下げることができる。また、蒸気吹出口15より吹き出される蒸気の上昇を蒸気吹出口15の上に設けた冷風吹出口16により吹き出される送風により抑制されるため、蒸気を遠くまで運ぶことができる。また、水槽6を熱伝導の良いアルミニウムで形成することで、加湿と同時に水槽6内の水が50℃〜70℃の湯に昇温されて加熱殺菌され、異臭の発生もなく、衛生性を兼ね備えた加熱式加湿器を提供できる。また、運転初期の水槽6内に有る水も加熱体8の運転開始に対し、送風ファン11の運転開始時間を遅らせることで、60℃以上に素早く加熱できるので、より早く殺菌ができる。また、蒸気温度T2を検出する蒸気温度センサ23を設けたことで、50℃以上になった場合、安全に停止させることもできる。また、清掃喚起ランプ26を設けたことで、蒸気温度T2が上昇する要因の吸い込み空気量不足改善のためのお手入れを使用者に喚起することができる。   As described above, according to the first embodiment, by providing the blower cylinder 13 that supplies air in the downward direction toward the bottom surface of the water tank 6 and the air intake inlet 12A that takes in air in the lateral direction, The steam temperature can be kept at 40 ° C. or less without unevenness. Further, by providing the heat radiating member 17 that is constantly cooled by the passage of air blow to the upper inner periphery of the steam guide tube 9, hot water flowing out of the water tank 6 contacts the heat radiating member 17 when the humidifier falls. And can be lowered to 50 ° C. or lower.
