Embodiment approach 1

[0033] One embodiment of the present invention will be described in detail based on the drawings. figure 1 It shows the schematic structure diagram of the refrigerator of this embodiment, and the same figure 1 (a) is a side sectional view of the refrigerator 30 of the present embodiment, and figure 1 (b) is the rear view of the same refrigerator 30, the same figure 1 (c) is the same figure 1 (b) Cross-sectional view of line Z-Z.

[0034] Such as figure 1 As shown in (a), the refrigerator 30 has a refrigeration cycle device 20, an outer case 40, an inner case 39, doors 62, 63, and an intermediate partition wall 50, and the inner case 39 is divided by the doors 62, 63 and the intermediate partition wall 50 to form There are refrigerator compartment 41 and freezer compartment 42 .

[0035] The refrigeration cycle apparatus 20 includes: a compressor 1; a radiator 2 connected to the discharge side of the compressor 1; and a first expansion valve as a decompression mechanism pr...

Embodiment approach 2

[0074] Next, refer to Figure 4 , to describe the second embodiment of the present invention. Figure 4 A side sectional view of refrigerator 70 showing this state. In addition, in Figure 4 In the refrigerator 30 of the above-mentioned first embodiment, the same reference numerals are used to perform the same or similar functions and effects. When compared with the refrigerator 30 of the above-mentioned first embodiment, the refrigerator 70 is different from the refrigerator 30 in that it has a refrigeration cycle device 21 that does not have the first heat exchanger 65 but Yes has a second heat exchanger 66 .

[0075] The second heat exchanger 66 is configured so that the liquid refrigerant separated by the gas-liquid separator 33 can exchange heat with the refrigerant from the heat absorber 14 . That is, the second heat exchanger 66 is formed between the refrigerant pipe 6C and the refrigerant pipe 6B. The second heat exchanger 66 can effectively supercool the liquid r...

Embodiment approach 3

[0077] Next, refer to Figure 5 , the third embodiment of the present invention will be described. Figure 5 A side sectional view of the refrigerator 90 showing this state. In addition, in Figure 5 Components with the same symbols as those in the above-mentioned embodiments have the same or similar functions and effects. When compared with the refrigerator 70 of the above-mentioned second embodiment, the refrigerator 90 is different from the refrigerator 70 in that it has the refrigeration cycle device 22 having the second heat exchanger 66, There is also a third heat exchanger 67 .

[0078] The third heat exchanger 67 is configured such that the refrigerant from the radiator 2 can exchange heat with the gas refrigerant separated by the gas-liquid separator 33 . That is, the third heat exchanger 67 is formed between the refrigerant pipe 6A and the refrigerant pipe 6D. Because through the third heat exchanger 67, in addition to obtaining the supercooling effect produced ...

Abstract

It is an object of the present invention to provide a refrigerator which is able to improve the efficiency of the refrigerating cycle while avoiding causing the structure of the refrigerator to be complicated, and avoiding a cost increase. Refrigerator (30) includes a refrigerating cycle device (20) having a compressor (1), a radiator (2) connected to a discharge side of the compressor (1), a first expansion valve (31) connected to an exit side of the radiator (2), a gas-liquid separator (33) for separating a refrigerant, which is in a mixed gas-liquid state by being decompressed by the first expansion valve (31), into a gas refrigerant and a liquid refrigerant, a heat absorber (14) into which the liquid refrigerant discharged from the gas-liquid separator (33) flows, and a refrigerant pipe (6D) for delivering the gas refrigerant discharged from the gas-liquid separator (33) into the middle pressure portion of the compressor (1); an outer case (40); an inner case (39); and a heat insulating material. The gas-liquid separator (33) is arranged in the heat insulating material (47).

Description

technical field [0001] The present invention relates to refrigerators. More specifically, the present invention relates to improvement of cooling capacity and high efficiency of refrigerators. Background technique [0002] In recent years, there has been an increasing demand for reducing the environmental load caused by the global warming problem, and many technologies aimed at reducing power consumption and improving the efficiency of cooling operation have been proposed even in refrigerators. [0003] For example, Patent Document 1 describes that the compression ratio of the compressor is reduced to perform high-efficiency operation by alternately and repeatedly cooling the refrigerator compartment and the freezer compartment. [0004] In addition, in Patent Document 2, it is described that for the purpose of providing an energy-saving refrigerator realized by improving the efficiency of the refrigeration cycle when the freezer compartment is cooled, the condensation tempe...
