ある（例えば実開昭61−195270公報）。(Prior art) As a conventional liquid receiver for a refrigeration system, for example, a desiccant is held between two holding plates attached to a suction pipe with a stopper such as a chrysanthemum washer. (For example, Utility Model Application Publication No. 195270/1983).
また、別の従来例として、ドーナツ状に形成し

で押え、さらに該押えプレートを別の止め金で固
定することにより行う。(Problem to be solved by the invention) In the former prior art described above, the desiccant assembly is
Before caulking and sealing the open bottom of the aluminum cylindrical body of the liquid receiver, with the cylindrical body upside down, one end of the suction pipe is assembled to the head of the cylindrical body,
Fix one stopper to this suction pipe, insert one presser plate until it hits the stopper, put desiccant onto this plate, press the desiccant with another presser plate, and then insert the presser plate again. This is done by fixing with another clasp.

且つ筒状体内の奥に入れた押えプレート状に乾燥
剤を入れるのでその作業がしにくい、(3)使用によ
り乾燥剤間の隙間が大きくなつて乾燥剤がガサつ
くため、押えプレートが動いてしまう等の問題点
がある。 However, with this conventional technology, (1) when fixing the stopper to the suction pipe, aluminum chips are generated because the iron stopper gouges the surface of the aluminum suction pipe; (2) If the desiccant is placed in the upper part of the liquid receiver, the fixing work of the stopper must be done on the liquid receiver. The work is difficult because it is carried out deep inside the cylindrical body, and the guide surface of the presser plate that comes into contact with the inner peripheral surface of the cylindrical body is short, making it difficult to insert the presser plate deep inside the cylindrical body.
In addition, the desiccant is placed in the shape of a presser plate that is placed deep inside the cylindrical body, which makes the work difficult. There are problems such as storage.

できない。 Furthermore, in the latter prior art, the desiccant shaped like a doughnut is placed on an expanded skirt provided at the tip of the discharge pipe, and this tip is placed on the bottom side of the liquid receiver. Therefore, this prior art cannot be applied when the desiccant is placed in the upper part of the liquid receiver.

目的としている。 The present invention was developed by focusing on these conventional problems, and it does not generate aluminum chips, and even when the desiccant is placed in the upper part of the liquid receiver, it is easy to dry. It is an object of the present invention to provide a liquid receiver for a refrigeration system that allows easy installation of a liquid.

できる。(Effects of the invention) As described in detail above, according to the liquid receiver for a refrigeration device according to the invention, two semi-cylindrical containers are connected to each other by a thin-walled hinge so as to be openable and closable, and at least a desiccant agent is contained in each container. a two-part container into which the two half-cylindrical containers are loaded, each having a half-cylindrical recess that fits into the suction pipe so as to hold the suction pipe in the center of each mating surface of the two half-cylindrical containers; By fitting a two-split container with a large number of pores in the upper and lower walls of the container into engagement grooves formed in each of the half-cylindrical containers into a flange formed in the suction pipe, or Each half-cylindrical container itself is attached to the suction pipe by being sandwiched between two flanges formed on the suction pipe, and the open lower end of the cylinder body is caulked and sealed to form a bottom. By fitting the engaging grooves of each semi-cylindrical container loaded with desiccant into the flange portion of the suction pipe outside the cylinder, or by inserting each semi-cylindrical container itself into the suction pipe. Since the two-split container is attached to the suction pipe by being sandwiched between two flanges, the desiccant can be easily assembled. In addition, after attaching the two-part container, when inserting the suction tube into the cylinder to fix one end of the suction tube to the head of the cylinder, the outer peripheral surface of each half-cylindrical container This guide surface, which serves as a guide surface, has a certain sufficient length, so
The 2-split container attached to the suction pipe can be easily placed deep inside the cylindrical body, that is, at the top of the cylindrical body.
従つて、アルミニウムの切粉が発生したりする
ことがなく、乾燥剤を受液器内の上部に配置する
場合にも乾燥剤の組付け作業を行うことができ
る。 Therefore, no aluminum chips are generated, and the desiccant assembly work can be performed even when the desiccant is disposed in the upper part of the liquid receiver.
また、乾燥剤は半筒形容器内に装填されている
ので、使用により乾燥剤間の隙間が大きくなつて
乾燥剤がガサついてきても、何等支障はない。 Further, since the desiccant is loaded in the semi-cylindrical container, there is no problem even if the gap between the desiccant becomes large and the desiccant becomes loose due to use.
