That is, in the present invention, when the internal pressure of the suction section is higher than the pressure inside the storage chamber, the pressure equalizing hole provided in the partition wall between the suction section and the storage chamber is opened by the opening/closing means, thereby preventing the liquid level within the storage chamber from rising. can. Further, when the pressure inside the suction section is lower than the pressure inside the storage chamber, the pressure equalization hole is closed, so that non-condensable gas can be sucked from the absorber shell.
以下、図面を参照して本考案の一実施例につい
て説明する。
An embodiment of the present invention will be described below with reference to the drawings.
第１図は本考案による吸収冷凍機の抽気装置の
概略を示すもので、図中６は吸引部１ａと貯室１
ｂとを仕切る隔壁である。この隔壁６の上部には
均圧孔７が設けられ、ゴムシート８により吸引部
１ａと貯室１ｂとの圧力差によつて自動的に開閉
するようになつている。すなわち、吸収部１ａ内
の圧力P1が貯室１ｂ内の圧力P2より高い場合、
ゴムシート８は第１図ａの如く均圧孔７から離れ
る方向に広がるので均圧孔７は開となり、これに
より吸収部１ａ内の圧力が均圧孔７を通つて貯室
１ｂ内に流れ込むので貯室１ｂ内のLiBr溶液３
が液位上昇するのを防止することができる。 FIG. 1 schematically shows the extraction device of an absorption refrigerator according to the present invention, in which 6 indicates the suction section 1a and the storage chamber 1.
This is a partition wall that separates the A pressure equalizing hole 7 is provided in the upper part of the partition wall 6, and is automatically opened and closed by a rubber sheet 8 depending on the pressure difference between the suction section 1a and the storage chamber 1b. That is, when the pressure P 1 in the absorption section 1a is higher than the pressure P 2 in the storage chamber 1b,
As the rubber sheet 8 spreads in the direction away from the pressure equalization hole 7 as shown in FIG. Therefore, LiBr solution 3 in storage chamber 1b
can prevent the liquid level from rising.
また、吸収部１ａ内圧力P1が貯室１ｂ内圧力
P2より低い場合にはゴムシート８は第１図ｂの
如く均圧孔７に密着する方向に吸引されるので均
圧孔７は閉となり、これにより吸収部１ａと貯室
１ｂとの間に圧力差が生じるので不凝縮ガスを吸
収器胴２から吸引することができる。 In addition, the pressure P 1 inside the absorption section 1a is the pressure inside the storage chamber 1b.
When the pressure is lower than P 2 , the rubber sheet 8 is sucked in the direction in which it comes into close contact with the pressure equalization hole 7 as shown in Fig. 1b, so the pressure equalization hole 7 is closed, and as a result, the gap between the absorption part 1a and the storage chamber 1b is Since a pressure difference is generated between the absorber shells 2 and 2, non-condensable gas can be sucked out of the absorber shell 2.
なお、上記実施例では均圧孔７を開閉する手段
としてゴムシート８を用いたが、例えば第２図に
示すように隔壁６の外周に円筒体９を設け、この
円筒体９に浮子１０を取付けるとともに、均圧孔
７と連通する連通孔１１を設けて円筒体９を貯室
１ｂ内の液位に応じて上下動させることにより均
圧孔７を開閉するようにしてもよい。 In the above embodiment, the rubber sheet 8 was used as a means for opening and closing the pressure equalizing hole 7, but for example, as shown in FIG. At the same time, the pressure equalizing hole 7 may be opened and closed by providing a communication hole 11 that communicates with the pressure equalizing hole 7 and moving the cylindrical body 9 up and down according to the liquid level in the storage chamber 1b.
