Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention is an improvement of a filtration reservoir of a refrigerant compressor, and more particularly to an improvement of a filtration reservoir of a refrigerant compressor suitable for a refrigeration machine and a home air conditioner.

[0002]

[Prior art]

 As shown in FIG. 2, the filtration reservoir of the conventional refrigerant compressor has a main body 17 part which is formed by combining both an upper main body 11 and a lower main body 12. In the manufacturing process of the members of the upper main body 11 and the lower main body 12, the iron plate is cut and formed, the manufacturing process is performed in the order of edge cutting punching and shaping drawing, and then the two members of the upper main body 11 and the lower main body 12 are pressed again. , It is formed on the body 17 by copper welding. Further, as shown in FIG. 2, the structure of the internal combining member is such that after the upper main body 11 and the lower main body 12 are completed by press working, the contact plate 14 and the filtration screen 15 are first joined to each other. After press-fitting into the main body 11, the lower main body 12 is pressure-welded to perform copper welding. After the copper welding is completed, the copper pipes such as the inner pipe 13 and the connecting pipe 16 are assembled to the main body 17, and then fixed by silver welding to complete the manufacture of the filtration reservoir.

[0003]

[Problems to be solved by the device]

 However, the upper body 11 and the lower body 12 of the conventional filtration liquid reservoir are cut and formed, and after being pressure-welded through the edge-cutting punching and shaping draw, they are integrally joined by copper welding. Therefore, the required manufacturing process and time are long, and the material consumption is large. Further, a defect of gas leakage may be caused at a copper welded joint portion between the upper body 11 and the lower body 12 due to defective welding or the like. When the inner copper tube 13 is attached to the main body 17, the positional relationship is likely to cause a center shift at the end, and the end is in a free end state. Therefore, when the compressor is operated, it resonates to generate noise, and the vibration is propagated to other parts of the machine body. As a result, noise is generated, the rigidity of the airframe is insufficient, and the materials used for the internal members, such as sleneless and expensive materials such as copper, are very much used.

The present invention has been made in view of the above point, and is manufactured by a casing in which the inner tube is securely fixed to the center of the main body, resonance noise is not generated, and the main body is integrally molded. It is an object of the present invention to provide a filtered liquid storage device.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention relates to a filter reservoir of a refrigerant compressor according to a member including a casing body, an inner pipe, a plug, a filtration screen, a suction pipe and a discharge pipe, wherein the casing body continuously presses an iron pipe. By processing, both ends are integrally formed into a throttle, the inner pipe is inserted into one end of the casing body and a plurality of holes are provided, the filtered refrigerant is guided to the inner pipe and expanded, and the plug is a plurality of inner pipes. It is fitted to the tip of the hole of the inside of the casing to prevent the refrigerant from directly entering the inner pipe, and the filter screen is provided inside one end of the casing body, and the suction pipe and the inner pipe are connected together to form a suction pipe. The refrigerant sucked in is filtered and guided to the inner pipe through a plurality of holes at the tip of the inner pipe.

The internal combination member uses a filtration screen in which the discharge pipe, the suction pipe, and the inner pipe are made of stainless steel, and they are connected by a well-known technique. In addition to the function of filtering the refrigerant, this filter screen also has the function of centering the inner pipe. As a result, center deviation, resonance, noise, etc. can be prevented, and the vibration generated when the compressor is operated by the coupling method can be reduced by the filter screen.

The filtration reservoir of the refrigerant compressor according to the present invention is a casing of which the casing body is integrally molded, and the iron pipe is manufactured by continuous press working, and both ends are integrated into a narrowed shape and a predetermined size. Since it is molded, by replacing the conventional pressing process for the upper and lower bodies with a continuous press drawing process, the pressure welding and welding processes required for the upper and lower bodies are not required. Therefore, time can be saved and cost can be reduced. Also, the amount of material used can be about 1/3 of the conventional type.

In the internal combination member, the discharge pipe, the suction pipe, and the inner pipe are integrally connected using a slenless filtration screen. Therefore, the stainless steel screen can achieve the effect of filtering the refrigerant, can secure the centering of the inner pipe, and has the function of a damper, so that the casing when the inner pipe is assembled is assembled. It is possible to secure the same center condition with the main body, and thereby reduce the noise. In addition, since it is possible to reduce the use of expensive materials such as stainless steel and copper used, it is possible to reduce the cost.
