Outline of the device The lower portion of the cylindrical container filled with the moisture absorbent is projected downward through the lower lid, and the lower end is the inner upper portion of the intake / exhaust pipe portion immersed in the oil in the oil cup, and the central portion is the ventilation hole, By providing at least one stepped lip portion having a sharp tip projecting obliquely downwardly from the center of the vent hole, oil rising along the inner wall surface of the intake / exhaust pipe portion is prevented, and the hygroscopic agent absorbs moisture due to the adhesion of oil. It prevents the deterioration of the capacity and makes it unnecessary to replenish the oil cup with oil.

ある。In FIG. 2, reference numeral 1 is a transparent cylindrical container made of glass or acrylic resin, and a hygroscopic agent 2 such as silica gel is filled inside through a wire mesh 3 provided so as to partition the lower part of the cylindrical container. Has been done. Reference numerals 4 and 5 denote an upper lid and a lower lid, respectively, of the cylindrical container 1. The lower lid 5 is provided with an intake / exhaust pipe portion 5A projecting downward through the lower lid 5 and surrounding the intake / exhaust pipe portion 5A. The bowl-shaped oil cup 6 provided in the
Is inserted so that the lower end of the intake / exhaust pipe 5A is immersed in the oil 7.

なっている。Further, a communication hole 8 is provided in a mounting portion between the oil cup 6 and the bottom lid 5 so that the oil cup 6 and the intake / exhaust pipe portion 5A communicate with the outside. In this way, the air in the cylindrical container 1 and the outside air are separated by the oil 6, and the outside air is filtered through the oil 7 and then guided to the hygroscopic agent 2 through the intake / exhaust pipe portion 5A.
D.考案が解決しようとする課題 油入電気機器運転中に、下端部が油７中に浸されている
吸排気管部5Aの内壁面を伝って前記油７が上昇し、吸湿
剤２に付着するので、吸入空気に対する吸湿能力を著し
く低下させる。そのため、吸湿剤２をしばしば交換しな
ければならなかった。D. Problems to be Solved by the Invention While the oil-filled electric device is operating, the oil 7 rises along the inner wall surface of the intake / exhaust pipe part 5A whose lower end is immersed in the oil 7 and adheres to the hygroscopic agent 2. Therefore, the moisture absorption capacity for the intake air is significantly reduced. Therefore, the hygroscopic agent 2 often had to be replaced.
また、油７が吸湿剤２に付着するので油カップ６内の油
量が不足し、これを度々補充しなければならないという
問題があった。Further, since the oil 7 adheres to the hygroscopic agent 2, the amount of oil in the oil cup 6 is insufficient, and there is a problem that it is necessary to replenish the oil frequently.
E.課題を解決するための手段 吸湿剤を充填した円筒容器の下蓋を貫通して下方に突出
し、且つ下端が油カップ内の油に浸された吸排気管部の
内側上部に、中心部を通気孔とし、該通気孔の中心斜め
下方に向かって突出した先端鋭角のリップ部を１段以上
設ける。E. Means for Solving the Problem A central portion is provided on the inner upper portion of the intake / exhaust pipe portion that penetrates the lower lid of the cylindrical container filled with the moisture absorbent and projects downward, and the lower end is immersed in the oil in the oil cup. The vent hole is provided with one or more stages of lip portions having an acute tip protruding downwardly from the center of the vent hole.
F.作用 吸排気管部の内壁面を伝って上昇した油は、吸排気管中
心部の通気孔の中心斜め下方に向かって突出したリップ
部の鋭角先端部に集まって油滴となり油カップ中に落下
し、更に上昇して吸湿剤部にまで到達することはなくな
る。F. Action The oil that has risen along the inner wall surface of the intake / exhaust pipe section gathers at the sharp tip of the lip that protrudes obliquely downward from the center of the vent hole at the center of the intake / exhaust tube and becomes an oil drop that drops into the oil cup. However, it will not further rise and reach the hygroscopic agent portion.
G.実施例 第１図は本考案の一実施例を示す図で第２図と同一部分
には同一符号を付して説明を省略する。G. Embodiment FIG. 1 shows an embodiment of the present invention, and the same parts as those in FIG.
第２図において述べた従来の技術と異なるところは、吸
排気管部5aの内側上部に中心部を通気孔とし、該通気孔
の中心斜め下方に向かって突出した先端鋭角のリップ部
９を設けた点にある。第１図においては該リップ部９を
３段設けた油上昇防止管10を、下蓋５と一体形成された
吸排気管部5aの内側上部に嵌装した例を示してある。2 is different from the conventional technique described in FIG. 2 in that the center portion of the intake / exhaust pipe portion 5a is a ventilation hole, and a lip portion 9 having a sharp tip projecting obliquely downward from the center of the ventilation hole is provided. In point. FIG. 1 shows an example in which an oil rise prevention pipe 10 provided with three stages of the lip portion 9 is fitted to the inside upper portion of an intake / exhaust pipe portion 5a integrally formed with the lower lid 5.
前記吸排気管部5aの内壁を伝って上昇した油７は前記リ
ップ部９の鋭角先端部に集まって油滴となり、油カップ
６中に落下してしまい、更に上昇して吸湿剤２にまで到
達することはなくなる。The oil 7 that has risen along the inner wall of the intake / exhaust pipe portion 5a gathers at the sharp tip of the lip portion 9 to form an oil drop, which falls into the oil cup 6 and further rises to reach the hygroscopic agent 2. There is nothing to do.
H.考案の効果 本考案によれば、吸湿剤を充填した円筒容器の下蓋を貫
通して下方に突出し、且つ下端が油カップ内の油に浸さ
れた吸排気管部の内壁面を前記油が伝って上昇し、吸湿
剤に油が付着して吸湿能力の低下をきたすことが無い。H. Effect of the Invention According to the present invention, the inner wall surface of the intake / exhaust pipe part, which penetrates the lower lid of the cylindrical container filled with the moisture absorbent and projects downward, and whose lower end is immersed in the oil in the oil cup Will not rise and the oil will not adhere to the hygroscopic agent to lower the hygroscopic ability.
従って、吸湿剤をしばしば交換したり、油カップ内の油
面低下により油の補充をしたりなどする必要は無くなる
という実用的効果を奏する。Therefore, there is a practical effect that it is not necessary to frequently replace the hygroscopic agent or replenish the oil due to a decrease in the oil level in the oil cup.
