【考案の詳細な説明】
本考案は加熱により発生させた蒸気を吐出させて加湿を
行う水加熱形加湿器の改良に関する。[Detailed Description of the Invention] The present invention relates to an improvement in a water heating type humidifier that performs humidification by discharging steam generated by heating.
従来、この種の加湿器においては第1図乃至第3図に示
すものが知られている。BACKGROUND ART Conventionally, as this type of humidifier, those shown in FIGS. 1 to 3 are known.
即ち第1図乃至第3図において、1は基台、2,3は夫
々基台1内に配設された加熱水槽及び水受室で、加熱水
槽2は基台1に立設された系内筒4に連通している。That is, in FIGS. 1 to 3, 1 is a base, 2 and 3 are a heating water tank and a water receiving chamber respectively arranged in the base 1, and the heating water tank 2 is a system installed upright in the base 1. It communicates with the inner cylinder 4.
5は水受室3を跨ぐようにして上面壁部1aに載置され
た給水タンクで、これと基台1内側面との間には所定間
隙を有し、外気がこの間隙A、給水タンク5の下面と水
受室3の水面との間(通気路B)及び案内筒4の下端の
吸気孔6を順に介して案内筒4内に流入する外気導入路
7(便宜上矢印で図示)を形成している。Reference numeral 5 denotes a water supply tank mounted on the upper wall 1a so as to straddle the water receiving chamber 3. A predetermined gap is provided between this and the inner surface of the base 1, and the outside air flows through this gap A and the water supply tank. 5 and the water surface of the water receiving chamber 3 (ventilation path B), and an outside air introduction path 7 (indicated by an arrow for convenience) that flows into the guide tube 4 through the intake hole 6 at the lower end of the guide tube 4 in order. is forming.
8は給水キャップで、これにより給水タンク5内の水が
給水キャップ8の下端開口を閉塞するまで水受室5内に
供給され、ホース9を介して加熱水槽2の水位が常に一
定に維持されるようになっている。Reference numeral 8 denotes a water supply cap, whereby the water in the water supply tank 5 is supplied into the water receiving chamber 5 until the lower end opening of the water supply cap 8 is closed, and the water level in the heating water tank 2 is always maintained constant via the hose 9. It has become so.
10はヒータ、11は蒸気吐出孔である。10 is a heater, and 11 is a steam discharge hole.
ヒータ10に通電すると、加熱水槽2内の水が加熱され
て蒸気を発生し、これが蒸気吐出孔11から吐出される
と共に外気が煙突効果によって外気導入路7を介して案
内筒4内に流入され蒸気温が安全な温度まで下げられる
ものであるが、この種加湿器では下記のような虞れがあ
った。When the heater 10 is energized, the water in the heating water tank 2 is heated to generate steam, which is discharged from the steam discharge hole 11 and outside air flows into the guide tube 4 through the outside air introduction path 7 due to the chimney effect. Although the steam temperature can be lowered to a safe temperature, this type of humidifier has the following risks.
即ち予想される最悪の場合として、例えば冬季給水タン
ク5に冷水を内部に空気が残る量補充した直後、この加
湿器を暖房された室の窓際に置いて、加湿運転した場合
、給水タンク5が直射日光に晒されると共に、高い室温
を受け、温度上昇(実験によると約26℃上昇した)す
る。In other words, in the worst case scenario, for example, if the humidifier is placed next to a window in a heated room and operated to humidify immediately after refilling the winter water tank 5 with cold water to the extent that air remains inside, the water tank 5 In addition to being exposed to direct sunlight, they are also exposed to high room temperature, causing the temperature to rise (according to experiments, it rose by about 26 degrees Celsius).
すると、給水タンク5内の空気が膨張され、膨張された
空気の圧力が給水タンク5内の水に作用するので、給水
タンク5内の水は給水キャップ8の下端開口が水受室3
の氷表面によって閉塞されているにも拘らず給水孔8a
を介して水受室3に異常に流出するようになる。Then, the air in the water supply tank 5 is expanded, and the pressure of the expanded air acts on the water in the water supply tank 5, so that the water in the water supply tank 5 is transferred to the water receiving chamber 3.
Although the water supply hole 8a is blocked by the ice surface of
The water begins to abnormally flow out into the water receiving chamber 3 through the water receiving chamber 3.
そして水受室3の水位は上昇して給水タンク5の下面に
達し、通気路Bが閉鎖され、結局外気導入路7が閉塞さ
れる。Then, the water level in the water receiving chamber 3 rises and reaches the lower surface of the water supply tank 5, and the ventilation path B is closed, and the outside air introduction path 7 is eventually closed.
実験によると、給水タンク5内に水が÷だけ入っている
とき、空気膨張による給水タンク5の流出水量が最大に
なり、ちなみに給水タンクの容積が3.41の場合、最
大流出水量は560 m lである。According to experiments, when the water tank 5 contains ÷ water, the amount of water flowing out of the water tank 5 due to air expansion is maximum.For example, when the volume of the water tank is 3.41, the maximum amount of water flowing out is 560 m It is l.
二のように異常水により外気導入路7が閉塞されると、
外気が案内筒4に流入しなくなり、案内筒4.の煙突効
果が無効化されて蒸気が室内筒4内に淀み、且つその一
部が吸気孔6を介して案内筒4外に流出して給水タンク
5に接触するようになる。If the outside air introduction path 7 is blocked by abnormal water as in 2.
Outside air no longer flows into the guide tube 4, and the guide tube 4. The chimney effect is nullified and the steam stagnates inside the indoor cylinder 4, and a part of it flows out of the guide cylinder 4 through the intake hole 6 and comes into contact with the water supply tank 5.
これにより給水タンク5内の空気は更に膨張され、給水
タンク5内の水を強制的に水受室3に流出させるように
なるので、加熱水槽2内の熱湯の水位が上昇し熱湯が吸
気孔6を介して水受室3側に逆流穴するようになる。As a result, the air in the water supply tank 5 is further expanded, and the water in the water supply tank 5 is forced to flow out into the water receiving chamber 3, so the water level of the hot water in the heating water tank 2 rises and the hot water is poured into the intake hole. 6, the water flows back to the water receiving chamber 3 side.
このように外気導入路7が閉塞されることによって、水
受室3は先の直射日光等に基づく異常流出水量に加えて
、前述の蒸気との接触に基づく流出水量を受け、加熱水
槽2から流入してくる熱湯を収容しきれなくなり遂には
熱湯が基台1の上端を乗り超えて外部に浴出し、火傷を
負うといった危険性があった。By blocking the outside air introduction path 7 in this way, the water receiving chamber 3 receives not only the abnormal amount of water flowing out due to direct sunlight, etc., but also the amount of water flowing out due to the contact with the steam mentioned above, and the water receiving chamber 3 receives the amount of water flowing out from the heating water tank 2. There was a danger that the inflowing hot water could no longer be accommodated and the hot water would eventually climb over the top of the base 1 and spill out to the outside, causing burns.
本考案は上記事情に鑑みてなされたもので、その目的は
、特に直射日光に晒され、若しくは高い室温を受ける事
情下にあって空気膨張に伴なう給水タンク内の水が異常
に流出しても、この異常水を溜め得て外気導入路の水に
よる閉鎖を阻止する補助水受室を設けることによって、
熱湯が外部に浴出することがなく、もって火傷の危険性
を回避できる水加熱形加湿器を提供するにある。The present invention was developed in view of the above circumstances, and its purpose is to prevent abnormal outflow of water in the water tank due to air expansion, especially when exposed to direct sunlight or exposed to high room temperature. However, by providing an auxiliary water receiving chamber that can store this abnormal water and prevent the outside air introduction channel from being closed by water,
To provide a water heating type humidifier which prevents hot water from leaking out to the outside and thereby avoids the risk of burns.

It is formed by making it into a depressed shape in the center of.
さて、20は前後両側に存する包囲壁部17の内周面に
沿って上面壁部16に一体に突設した一対の載置台で、
これには後述する給水タンクが載置されるようになって
いる。Now, reference numeral 20 denotes a pair of mounting tables that are integrally provided on the upper wall part 16 along the inner circumferential surface of the surrounding wall part 17 on both the front and rear sides,
A water tank, which will be described later, is mounted on this.
21は案内筒13に連通ずるようにして基台12内に配
設された加熱水槽で、この加熱水槽21と主水受室19
とは夫々の底壁にて連通管22によって連通されている
。Reference numeral 21 denotes a heating water tank disposed within the base 12 so as to communicate with the guide tube 13, and this heating water tank 21 and the main water receiving chamber 19
are communicated with each other by a communication pipe 22 at the bottom wall of each.
23は包囲壁部17内に位置して載置台20に載置され
た給水タンクで、この状態にて反吸気孔18側の包囲壁
部17と給水タンク23側面との間には夫々所定の間隙
C,Dを形成すると共に、給水タンク23の下面と上面
壁部16との間には所定容積の空間、即ち補助水受室2
4を形成している。Reference numeral 23 denotes a water tank located within the surrounding wall 17 and placed on the mounting table 20. In this state, there are predetermined gaps between the surrounding wall 17 on the side opposite to the intake hole 18 and the side surface of the water tank 23. Gaps C and D are formed, and a space of a predetermined volume is formed between the lower surface of the water tank 23 and the upper wall portion 16, that is, the auxiliary water receiving chamber 2.
4 is formed.
これによって外気が間隙C9補助水受室245間隙り及
び吸気孔18を順に介して蒸気室15に導入される外気
導入路25(便宜上矢印で図示する)を形成している。This forms an outside air introduction path 25 (indicated by an arrow for convenience) through which outside air is introduced into the steam chamber 15 through the gap C9, the auxiliary water receiving chamber 245, and the intake hole 18 in this order.
26は給水タンク23の下面部に突設された給水口体で
、これには給水キャップ27が生水受室19を臨むよう
にして螺着されている。Reference numeral 26 denotes a water supply port protruding from the lower surface of the water tank 23, onto which a water supply cap 27 is screwed so as to face the raw water receiving chamber 19.
この給水キャップ27において、28はこれの中央に穿
設された給水孔、29は支持枠30を介して給水(L2
8を挿通する弁棒で、これの上端部には、給水(L28

棒33に当接され、この状態では弁棒29の下半部分の
囲りに設けたばね34の弾発力に抗して弁体32が給水
孔28を開放し、給水タンク23内の水が給水孔28を
介して生水受室19に供給され、水位が上昇して氷表面
によって給水キャップ27の下端開口27 aが閉塞さ
れると、給水タンク23からの給水が停止されるように
なり、これによって加熱水槽21の水位が常に一定に維
持されるようになっている。In this water supply cap 27, 28 is a water supply hole bored in the center thereof, and 29 is a water supply hole (L2) through a support frame 30.
The valve stem is inserted through L28, and the upper end of the valve stem has a water supply (L28
A valve element 32 for configuring a water supply valve 31 that opens and closes is attached, and its lower end abuts against a locking rod 33 protruding from the inner bottom surface of the raw water receiving chamber 19. In this state, the valve rod 29 The valve body 32 opens the water supply hole 28 against the elastic force of the spring 34 provided around the lower half of the tank, and the water in the water tank 23 is supplied to the raw water receiving chamber 19 through the water supply hole 28. When the water level rises and the lower end opening 27a of the water supply cap 27 is blocked by the ice surface, the water supply from the water supply tank 23 is stopped, thereby maintaining the water level in the heating water tank 21 at a constant level. It is now possible to do so.
ところで、前記補助水受室24の容積の設定、即ち載置
台20の高さの設定にあたっては、給水タンク23内に
その容積の士だけ水が入っているとき、約26℃だけの
温度上昇を受け、このときに給水タンク23から流出す
る流出水量を実験及び設計的に求め、その流出水量を若
干上まわる容積を補助水受室24の容積に等しく設定し
ている。By the way, when setting the volume of the auxiliary water receiving chamber 24, that is, setting the height of the mounting table 20, when the water tank 23 contains water equal to its volume, the temperature should rise by about 26°C. At this time, the amount of water flowing out from the water supply tank 23 is determined experimentally and by design, and a volume slightly larger than the amount of water flowing out is set equal to the volume of the auxiliary water receiving chamber 24.
この設定の事情に関しては下記の考察に基づいている。The circumstances surrounding this setting are based on the following considerations.
給水タンク23内の空気容積の増加に依存して膨張空気
容積は増加し、流出水量は増大する条件下にあるので、
例えば運転初期において、給水タンク23内の水量が多
く、従って空気容積が小さい場合、膨張空気量は少なく
、流出水量も少ない。Since the expanded air volume increases depending on the increase in the air volume in the water supply tank 23, and the amount of outflow water increases,
For example, at the beginning of operation, if the amount of water in the water supply tank 23 is large and therefore the air volume is small, the amount of expanded air is small and the amount of water flowing out is also small.
これとは反対に、給水タンク23内で水量に対して空気
容積が極端に大きい場合は、膨張空気量が多くなるが収
容水量が元々少ないので流出水量も少ない。On the contrary, if the air volume is extremely large relative to the water volume in the water supply tank 23, the amount of expanded air will be large, but since the amount of stored water is originally small, the amount of outflow water will also be small.
一方、運転中の事情としては、運転時間の経過に伴って
給水タンク23内の水量が減少し、空気容積が漸次増大
するに従い、膨張空気容積も増大し、流出水量が次第に
増大するが、給水タンク23の水量が給水タンク23の
容積に対して十分少なくなると給水タンク23が軽くな
るので膨張空気に相当する規定の水量が流出する前に給
水キャップ27のばね34の弾発力が水を含めた給水タ
ンク23の重量に打勝って、これにより給水タンク23
が弁棒30を介して持ち上げられるようになって給水孔
28が弁体32によって閉塞されてしまい、給水タンク
23から水がこれ以上流出するのが阻止される。On the other hand, as for the circumstances during operation, the amount of water in the water supply tank 23 decreases as the operation time passes, and as the air volume gradually increases, the expanded air volume also increases, and the amount of outflow water gradually increases. When the amount of water in the tank 23 becomes sufficiently small compared to the volume of the water tank 23, the water tank 23 becomes lighter, so that the elastic force of the spring 34 of the water cap 27 absorbs water before the specified amount of water corresponding to the expanded air flows out. This overcomes the weight of the water tank 23, which makes the water tank 23
is lifted up via the valve stem 30, and the water supply hole 28 is closed by the valve body 32, preventing any further water from flowing out from the water supply tank 23.
結局給水孔28が弁体32によって閉塞される前後の情
況を勘案して給水タンク23にこの容積の約キだけ水が
入っているとき最大の流出水量になることが判明した。After taking into account the circumstances before and after the water supply hole 28 is closed by the valve body 32, it has been found that the maximum amount of water flows out when the water supply tank 23 contains water approximately equal to this volume.
尚、35は加熱水槽21の外底壁に装着されたヒータで
ある。Note that 35 is a heater attached to the outer bottom wall of the heating water tank 21.
いま、上記構成において、図示しないスイッチによりヒ
ータ35に通電すると、加熱水槽21が加熱されて蒸気
を多量に発生する。Now, in the above configuration, when the heater 35 is energized by a switch (not shown), the heating water tank 21 is heated and a large amount of steam is generated.
こうして発生した蒸気は吸気孔18から煙突効果によっ
て吸入された空気と混合されながら適温となって蒸気室
15を上昇し、吐出孔14から外部に吐出されて加湿が
行なわれるものである。The steam generated in this way is mixed with the air taken in by the chimney effect from the intake hole 18, reaches an appropriate temperature, rises in the steam chamber 15, and is discharged to the outside from the discharge hole 14, thereby performing humidification.
さて、運転中直射日光等のもとで、約26℃だけの温度
上昇を受け、水が給水タンク23内にその容積の+だけ
入っていたとき、空気膨張により給水タンク23から最
大の水量が流出するが、本実施例によれば、補助水受室
24の容積を上記最大流出水量を若干上まわる容積に設
定しているので、生水受室29の規定水位を超える流出
水量即ち異常水は全て補助水受室24に収容され、補助
水受室24の水面は給水タンク23の下面に達すること
はなく、従って外気導入路25が水によって閉塞される
ことがなく、案内筒13の煙突効果が良好に維持され、
吐出孔14からの蒸気の吐出が良好に続行される。Now, when the temperature rises by about 26 degrees Celsius under direct sunlight etc. while driving, and when water is in the water tank 23 by its volume, the maximum amount of water will be removed from the water tank 23 due to air expansion. However, according to this embodiment, the volume of the auxiliary water receiving chamber 24 is set to be slightly larger than the maximum amount of water flowing out, so that the amount of water flowing out exceeding the specified water level of the raw water receiving chamber 29, that is, abnormal water. are all accommodated in the auxiliary water receiving chamber 24, and the water level of the auxiliary water receiving chamber 24 does not reach the lower surface of the water supply tank 23. Therefore, the outside air introduction passage 25 is not blocked by water, and the chimney of the guide tube 13 The effect is well maintained,
The discharge of steam from the discharge hole 14 continues satisfactorily.
よって蒸気が案内筒13内に淀み、蒸気の一部が吸気孔
18を介して給水タンク23に接触することが防止され
るので、熱湯が外部に浴出して火傷を負うといったこと
は回避し得る。Therefore, the steam stagnates in the guide tube 13 and a part of the steam is prevented from coming into contact with the water supply tank 23 through the intake hole 18, so it is possible to avoid the possibility of hot water leaking outside and causing burns. .
特にこの実施例では補助水受室24の底面を上面壁部1
6を兼用するようにして補助水受室24の底面をできる
だけ広くとつねいるので、水位の上昇率を低く抑え得て
、スペース的に余裕のある外気導入路25を確保できる
ものである。In particular, in this embodiment, the bottom surface of the auxiliary water receiving chamber 24 is
Since the bottom surface of the auxiliary water receiving chamber 24 is made as wide as possible so as to be used also as a water receiving chamber 6, the rising rate of the water level can be suppressed to a low level, and an outside air introduction path 25 with sufficient space can be secured.

器を提供できるものである。As explained above, even if water in the water supply tank abnormally flows out due to air expansion, particularly under conditions of exposure to direct sunlight or high room temperature, the present invention can store the amount of water that flows out. By providing an auxiliary water receiving chamber that prevents the outside air introduction path from being closed by water, it is possible to provide a water heating type humidifier that prevents hot water from leaking outside and thereby avoids the risk of burns. It is something.
