Description

Embodiments of this invention relate to refrigerators. A refrigerator incorporates a compressor and condenser, which form part of the refrigeration cycle, along with a cooling fan located in a machine compartment at the rear of the refrigerator body. In such refrigerators, the cooling fan is rotated in conjunction with the compressor's operation to improve heat dissipation efficiency within the machine compartment, thereby reducing the refrigerator's power consumption (for example, see Patent Document 1 below). However, due to the growing environmental awareness in recent years, there is a strong demand for energy conservation, and further improvements in heat dissipation efficiency within the machine room are desired. Japanese Patent Publication No. 2011-231948 A longitudinal cross-sectional view showing the schematic configuration of a refrigerator according to the first embodiment of the present invention.A schematic diagram showing the refrigeration cycle device in a refrigerator according to the first embodiment of the present invention.A view of the machine room from the rear, with the rear grille removed.Cross-sectional view along line A-A in Figure 1Perspective view of the mounting bracketEnlarged view of the main part in Figure 4Side view of the machine room The following describes a refrigerator 10 according to one embodiment of the present invention, based on the drawings. (1) Configuration of the refrigerator 10 The refrigerator body 12 of the refrigerator 10 is composed of an outer box 12a, an inner box 12b, and an insulated space 12c formed between them where an insulating material is provided. The refrigerator body 12 has a refrigerator compartment 14, a vegetable compartment 16, a first freezer compartment 18, and a second freezer compartment 20 arranged from the top, and an ice-making compartment (not shown) is located next to the first freezer compartment 18. An insulating partition wall 24 is provided horizontally between the refrigerated space composed of the refrigerator compartment 14 and the vegetable compartment 16 and the freezer space composed of the ice-making compartment, the first freezer compartment 18, and the second freezer compartment 20. A refrigerator cooler 26 is installed behind the refrigerator compartment 14 and the vegetable compartment 16 to cool the refrigerated space, which consists of a refrigerator compartment 14 and a vegetable compartment 16. Above the refrigerator cooler 26 is a refrigerator fan 28 that blows the cold air generated by the refrigerator cooler 26 into the refrigerated space. A refrigeration cooler 30 is installed on the upper rear of the second freezer compartment 20 to cool the freezing space, which consists of an ice-making compartment, a first freezer compartment 18, and a second freezer compartment 20. Above this refrigeration cooler 30, a refrigeration fan 32 is provided to blow the cold air generated by the refrigeration cooler 30 into the freezing space. A machine room 22 is located at the rear of the bottom of the refrigerator body 12, that is, behind the freezer compartment 20. The machine room 22 houses the compressor 36, condenser 58, and heat dissipation fan 56, which form part of the refrigeration cycle 84, as well as an evaporation tray 60 that receives defrost water generated from the refrigeration cooler 30 via pipes 34. This machine room 22 will be explained in more detail later. (2) Configuration of the refrigeration cycle 84 Next, the configuration of the refrigeration cycle 84 of the refrigerator 10 of this embodiment will be described with reference to Figure 2. The refrigeration cycle 84 is configured such that, starting from the refrigerant outlet 36b of the compressor 36 which discharges high-temperature, high-pressure gaseous refrigerant, the following components are connected in order: the evaporation pipe 70, the condenser 58, the heat dissipation pipe 88, the anti-condensation pipe 90, the dryer 92, and the inlet side of the switching valve 94. One outlet of the switching valve 94 is sequentially connected by piping to a refrigerated capillary tube 96, a refrigerated cooler 26, and a refrigerated suction pipe 72, which serve as pressure reducing means. The other outlet of the switching valve 94 is sequentially connected by piping to a refrigerated capillary tube 98, a refrigerated cooler 30, a refrigerated suction pipe 74, and a check valve 75, which also serve as pressure reducing means. The outlet side of the check valve 75 and the outlet side of the refrigerated suction pipe 80 are connected via a joint 76 to a single connecting pipe 78, and the outlet side of the connecting pipe 78 is connected to the refrigerant inlet 36a of the compressor 36. In this type of refrigeration cycle 84, the refrigerant sealed within the cycle is compressed by the compressor 36, transforming into a high-temperature, high-pressure gaseous refrigerant. It then dissipates heat as it flows through the evaporation pipe 70, condenser 58, he
