す。Conventional configuration and problems A typical refrigeration cycle has a compressor 1 as shown in Figure 1.
．． Condenser 2. Expander 3. Evaporator 4. It is composed of an accumulator 5. The refrigerant medium is compressed by a compressor 1, passes through a condenser 2, is condensed here, is depressurized by an expander 3, and passes through an evaporator 4.
The cycle of passing through the Muretaro and returning to the compressor 1 is repeated.

穴１１ａが設けられている。In the conventional accumulator, as shown in FIG. 2, the inlet pipe 9 of the accumulator 5 is connected to the outlet of the evaporator 4 through a pipe line.
The opening 1 inside the accumulator 5 and the other end 8b of the inner tube 8 are connected to the suction lower of the compression mechanism section 6. This inner tube 8 passes through the interior 1o of the accumulator 6 and extends toward the inlet tube 9. Further, inside the accumulator 10, a baffle 11. A wire mesh 12 is provided respectively. Further, the baffle 11 is provided with a through hole 11a through which a refrigerant passes, as shown in FIG.

機構部６の吸入ロアに導かれ圧縮される。When the compressor having the above structure is operated, the rotor 14 of the electric motor section 13 rotates, and the shaft 16 and rollers 16 of the compressor section 6 rotate.
The refrigerant passes through the accumulator 5, is guided to the suction lower of the compression mechanism section 6, and is compressed.

機構部６内にて圧縮される。Figure 3 shows the flow of refrigerant in the Aki Muretaro. The refrigerant enters the inlet pipe 9 of the accumulator 6, passes through the wire mesh 12, passes through the through hole 11a of the baffle 11, and accumulates as a refrigerant liquid below the inside 10 of the accumulator. This refrigerant liquid gradually vaporizes and is sucked in from the tip 8a of the inner tube 8, flows into the suction port of the compression mechanism section 6 through the inner tube 8, and is compressed within the compression mechanism section 6.

、入力を低減させ、成績係数を向上させることは非常に
困難である。However, in this structure, since the diameter of the inner pipe 8 of the accumulator 5 is uniform, when the compressor is operated, it is not possible to obtain the optimum suction pressure in the accumulator, which adversely affects the refrigerating capacity and input, resulting in poor performance. This could sometimes make the coefficient worse. In particular, the suction pressure inside the accumulator section is affected by the passage area of the inner tube 8, the length of the inner tube 8, the inner cross-sectional area of the accumulator 5, and the length of the accumulator 6, so the diameter of the inner tube 5 can be varied. However, it is difficult to improve the coefficient of performance. That is, in conventional accumulators, the inner cross-sectional area of the accumulator 5, the length of the accumulator 6, and the length of the inner tube 8 are generally fixed, and when the inner cross-section M of the inner tube 8 is changed, the cross-sectional area becomes smaller. Refrigeration capacity and input both increase,
On the other hand, if the cross-sectional area is large, both the refrigerating capacity and input tend to decrease, and it is extremely difficult to improve the refrigerating capacity, reduce the input, and improve the coefficient of performance using inner tubes with the same cross-sectional area. .

実施例の説明
以下、本発明の実施例を添付図面の第４図〜第６図を参
考に説明する。DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to FIGS. 4 to 6 of the accompanying drawings.

延長方向に取付けられている。In FIG. 4, the 13-cylindrical accumulator has an inner tube 14 extending in the direction of the inlet tube 16 in the interior 16 of the accumulator 13. A small diameter portion 14C is formed at the tip 14a of the accumulator interior 16 of the inner pipe 14 by drawing or the like, and the small diameter portion 140 has an inner diameter d and a length l such that the coefficient of performance during compressor operation is the best. Each is set. Further, the other end 14b of the inner tube 14 is connected to the suction port of the compression mechanism section 6. Reference numeral 17 denotes a baffle, which has a through hole 17a formed so as not to overlap with the inner tube 14, and is attached together with a wire mesh 18 in the extending direction of the inner tube 14 on the inlet tube 16 side.

ができる。When the compressor is operated using the accumulator with the above structure, the refrigerant passes through the inlet pipe 16, the wire mesh 18, and the baffle 1.
70 through holes 17a and accumulate in the lower part of the accumulator interior 16. Furthermore, the accumulator internal 16
The refrigerant accumulated in the tube gradually vaporizes and reaches the tip 1 of the inner tube
It is inhaled from 4a. Here, the tip 14a of the inner tube
The small diameter portion 14C formed in 16 is formed so that the suction pressure is the highest. In addition, the inner pipe 14 has a middle part 146 thicker than the small diameter part 14C so that the pipe resistance can be reduced when the refrigerant sucked into the inner pipe 14 passes through the interior 14d, so that the refrigerating capacity can be improved. , the input can be reduced at the same time.
つまり、一般的には、内管１４を全体に細くすれば、冷
凍能力は向上するが、入力も上がり、成績係数は上がら
ない。逆に、内管１４を全体に太くすると、冷凍能力は
下がり、入力も下がるが、同様に成績係数は上がらない
。That is, generally speaking, if the inner tube 14 is made thinner overall, the refrigerating capacity will improve, but the input will also increase and the coefficient of performance will not increase. Conversely, if the inner tube 14 is made thicker as a whole, the refrigerating capacity and the input power will decrease, but the coefficient of performance will not increase as well.
ところが本発明では、前記の両方の長所を組合せ、冷凍
能力を向上させ、入力を低減し、成績係数を上げること
ができる。However, the present invention combines the above-mentioned advantages, improves the refrigeration capacity, reduces input, and increases the coefficient of performance.

The same effect as described above can be obtained by connecting b by welding or the like. Further, as shown in FIG. 6, the same effect can be obtained by forming a small diameter portion 14g at the front end portion 148 of the compression mechanism portion 6 of the inner tube 14 on the suction port T side by drawing. .
