Abstract

PROBLEM TO BE SOLVED: To achieve a rationalization of material costs and improvements in transportation and assembling work, by shortening an evaporation refrigerant return tube in a refrigerator in which a cooler is provided at the center part of the rear of the body of the refrigerator. SOLUTION: A piping part 16 on which a capillary tube 15 for a refrigerant is integrally soldered one back and forth and a half parallel with a part of an evaporation refrigerant return tube 14 to secure a heat exchange performance is arranged on a cooling system above a cooler without bypassing the evaporation refrigerant return tube 14. Moreover, the ratio of the length is set at about 2:1 between the capillary tube 15 for the refrigerant and the evaporation refrigerant return tube 14. This constitution achieves a saving of resources of the evaporation refrigerant return tube 14, a prevention of poor bending in the working process with the miniaturization of the piping part 16 and improvements in assembling work.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a cooling system for a refrigerator or the like.

[0002]

2. Description of the Related Art In recent years, in order to increase the capacity of a freezing room and increase the usability thereof with the increasing use of frozen foods, a freezing room is formed in the middle part of the refrigerator body. Conventionally, this type of cooling system is disclosed in Japanese Patent Application Laid-Open No. 2-192570. As shown in FIG. 3, reference numeral 1 denotes a refrigerator main body, which includes a refrigerator room 2 in an upper stage, freezing rooms 3 and 4 in a middle stage, and a vegetable room 5 in a lowermost stage. Further, the temperature of each room shown in the figure represents a temperature zone of each room when the outside air temperature is 30 ° C. and there is no load in a typical refrigerator. As shown in FIG. 4, the piping of the cooling system of the refrigerator, as shown in FIG. Dryer 1 that is radiated and completes necessary and sufficient heat radiation and liquefied refrigerant is filled with a desiccant.
After passing through 0, the refrigerant evaporates and evaporates in the cooler 12 through the capillary tube 11 for the refrigerant, returns to the compressor 6 through the evaporative refrigerant return tube 13, and repeats the cooling cycle. However, in FIG. 4, the refrigerant capillary 11 and the evaporated refrigerant return pipe 13 are shown separately for easy understanding, but actually, as shown in FIGS. 11 is soldered in a straight line parallel to a part of the evaporative refrigerant return pipe 13, then bent into a required shape, piped as a cooling system, and assembled in a refrigerator. In this case, the refrigerant capillary 11 and the evaporative refrigerant return pipe 1
The length ratio to 3 is about 2 /
It is set to about 1.7.

[0003]

However, in the above-mentioned conventional construction, the refrigerator 12 is arranged at the center of the rear surface of the refrigerator body and the distance from the compressor 6 is such that the refrigerator is arranged at the uppermost stage. Despite being relatively shorter than the above, it is a wasteful pipe in terms of cost in that the evaporative refrigerant return pipe 13 that has exited the cooler 12 is largely bypassed upward and returned to the compressor 6. Soldering with the evaporating refrigerant return pipe 13 and bending to the required shape, and handling is difficult and easy to deform even in the transport work during the process,
Further, in assembling from the back of the refrigerator main body, there is a problem that useless man-hours such as temporary fixing are required.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and refrigeration system for saving resources by rationally arranging a capillary for refrigerant and a return pipe for evaporating refrigerant, and for facilitating transportation and assembly work. An object of the present invention is to provide a refrigerator provided with the above.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a refrigerant capillary and an evaporative refrigerant return pipe having a length ratio of about 2/1, and is provided in parallel with a part of the evaporative refrigerant return pipe. This is a cooling system provided with piping components in which a capillary for refrigerant is soldered for one and a half round trips. By arranging the cooling system, it is possible to save resources of piping materials and to facilitate transporting and assembling operations.

A cooling system is provided in which a capillary is bent over one and a half round trips and a piping component soldered is provided.

As described above, in the refrigerator provided with the cooler at the center of the rear surface of the refrigerator main body, it is possible to save resources of the evaporative refrigerant return pipe, prevent deformation during the transfer operation, and rationalize man-hours for temporary fixing in the assembling operation. .

Embodiments of the present invention will be described below with reference to the drawings. The same components as those of the related art are denoted by the same reference numerals, and detailed description thereof will be omitted.

An evaporative refrigerant return pipe 14 connected to a cooler 12 provided at a central portion on the back of the refrigerator body 1 is connected to a compressor 6 provided below without largely detouring upward. Parallel to a part of the refrigerant capillary 15
By soldering to increase the heat dissipation effect and ensure the cooling performance. In order to secure this cooling performance, the evaporative refrigerant return pipe 14 is shortened, but the refrigerant capillary 15
The length of the refrigerant capillary 15 and the evaporative refrigerant return pipe 14 is about 2/1. As shown in FIG. 1, the refrigerant capillary 15 extends over one and a half reciprocation in parallel with a part of the evaporated refrigerant return pipe 14.
2 (a) and 2 (b) to form an integral piping component 16 by inserting it from the back of the refrigerator main body 1 and connecting it to the cooler 12 and the compressor 6. The cooling system has been completed.

As described above, according to the first aspect of the present invention, the evaporative refrigerant return pipe exiting the cooler is connected to the compressor provided below without being largely bypassed upward. In addition, the length of the evaporative refrigerant return pipe is greatly reduced to save resources, and the refrigerant capillary is soldered for one and a half round trips in parallel with a part of the evaporative refrigerant return pipe with the conventional length. Bending to a required shape can be facilitated, and deformation during transfer operation can be prevented. Furthermore, the assemblability to the back of the refrigerator main body can be improved, and the work can be rationalized.
