本発明は加湿装置に係り、更に詳細には加湿装
置の給水タンクの構造に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a humidifier, and more particularly to the structure of a water tank of a humidifier.
従来より、超音波振動子を使用して水を霧化し
加湿を行う超音波加湿装置が広く実用化されてい

として使用する場合には、装置が寒冷時に凍結す
ることもあり、その対策が必要とされていた。
BACKGROUND ART Ultrasonic humidifiers that use ultrasonic transducers to atomize and humidify water have been widely put into practical use. When this type of humidifying device is used as a humidifying device for the interior of an automobile, the device may freeze in cold weather, and countermeasures have been required.
そこで、従来は、例えば特開昭55−72742号公
報等に開示されるように、凍結時に超音波振動子
を駆動させないように配慮して部品に不具合が生
じるのを防止している。 Therefore, conventionally, as disclosed in, for example, Japanese Unexamined Patent Application Publication No. 55-72742, care has been taken not to drive the ultrasonic transducer during freezing to prevent defects in the parts.
また、給水タンクが満水状態にある時に凍結現
象が発生した場合には、氷による体積膨張により
給水タンクが破壊するおそれがあるため、従来よ
り次のような対処がなされている。 Furthermore, if a freezing phenomenon occurs while the water supply tank is full of water, there is a risk that the water supply tank may be destroyed due to volumetric expansion due to ice, so the following countermeasures have been conventionally taken.
例えば、実開昭59−116256号公報に開示される
ように、給水タンク内に収縮性を有する空気袋を
収容したり、
第２図に示すように、給水タンク７の注水口７
ａに、給水タンク７の内部に突出する中空筒部７
ｂを延設したものがある。 For example, as disclosed in Japanese Utility Model Application Publication No. 59-116256, a contractible air bag may be housed in the water tank, or as shown in FIG.
In a, a hollow cylindrical portion 7 protruding into the inside of the water tank 7
There is an extension of b.
前者の場合には、給水タンクが満水或いはこれ
に近い状態にあるときの凍結時の氷の堆積膨張を
空気袋が吸収して、給水タンクの破壊を防止す
る。 In the former case, when the water supply tank is at or near full, the air bladder absorbs the accumulation and expansion of ice during freezing, thereby preventing the water supply tank from being destroyed.
後者の場合には、第２図に示すように、注水時
に給水タンク７内の水１６が中空筒部７ｂ下端ま
での所定の水位に達すると、水１６の水面が中空
筒部７ｂ外側面とタンク７の上部内側面７ｃとで

る。この空間２０の存在により、給水タンク７に
所定量以上の注水を行つても、水１６の水位が中
空筒部７ｂの下端レベル以上になることなく、空
間２０による空気容積が確保される。 In the latter case, as shown in FIG. 2, when the water 16 in the water supply tank 7 reaches a predetermined water level up to the lower end of the hollow cylinder part 7b during water injection, the water surface of the water 16 touches the outer surface of the hollow cylinder part 7b. A space 20 surrounded by the upper inner surface 7c of the tank 7 is sealed to isolate the space 20 from the atmosphere. Due to the existence of this space 20, even if a predetermined amount or more of water is poured into the water supply tank 7, the water level of the water 16 does not exceed the level of the lower end of the hollow cylindrical portion 7b, and the air volume is ensured by the space 20.
従つて、注水口７ａに給水栓付きキヤツプを被
着して、この注水口７ａを下向きにして給水タン
ク７を倒立状態で加湿装置本体にセツトしても、
常に給水タンク７内には空間２０の容積分に相当
する空気層が存在するので、タンク水が凍結して
も、その氷の体積膨張を空気層により吸収し給水
タンクの破壊を防止できる。 Therefore, even if a cap with a water supply tap is attached to the water inlet 7a and the water tank 7 is set in the humidifier main body in an inverted state with the water inlet 7a facing downward,
Since there is always an air layer corresponding to the volume of the space 20 in the water supply tank 7, even if the tank water freezes, the volumetric expansion of the ice is absorbed by the air layer and the water supply tank can be prevented from being destroyed.
この中空筒部７ｂにより空気容積を確保する方
式は、空気袋を不要にすることができ、給水タン
クそのもので給水タンクの凍結破壊を防止できる
利点があるが、次のような改善すべき点があつ
た。 This method of securing air volume using the hollow cylindrical portion 7b has the advantage of eliminating the need for an air bag and preventing the water tank from freezing and breaking in the water tank itself; however, there are the following points that need to be improved. It was hot.
すなわち、このような方式によれば、第３図に
示すように給水タンク７を倒立させて加湿装置本
体にセツトさせた場合に、給水タンク７内の水が
給水により減ると、最終的に水１６が中空筒部７
ｂの高さまで残り、その分だけ、給水容量が犠牲
になる。
That is, according to such a system, when the water supply tank 7 is set upside down and set in the humidifier main body as shown in Fig. 3, if the water in the water supply tank 7 decreases due to water supply, the water will eventually disappear. 16 is the hollow cylinder part 7
The water remains up to the height b, and the water supply capacity is sacrificed by that amount.

With such a configuration, when filling water into the water tank 7, the water inlet 7a is turned upward and the cap 8 with the water tap 12 is removed. The drain valve 31 is pressed and sealed against the wall surface of the hollow cylindrical portion 7b by the force of the spring 32, and is in a closed state. As a result, a space 20 similar to that shown in FIG. 2 is secured, and a cap 8 with a water supply tap is attached to the water inlet 7a, and the water supply tank 7 is held upside down with the water inlet 7a facing downward. Even if it is set to 1, an air layer corresponding to the volume of the space 20 is always secured in the water supply tank 7 to prevent the tank from freezing and breaking.
