Figure 4 is a diagram showing the inside of the machine room from the rear. Figure 5 is a plan view showing the air flow inside the machine room with arrows.

Referring to FIGS. 4 and 5 , the refrigerator 1 may include a cold air generating unit that supplies cold air to the storage compartment 20 . The cold air generating unit may include a compressor 110, a condenser 120, an expansion valve (not shown), and an evaporator (not shown). The cold air generating unit 50 operates a refrigeration cycle using a compressor 110, a condenser 120, an expansion valve, and an evaporator, and can generate cold air through this.

The compressor 110 compresses the refrigerant to a high temperature and high pressure state. The compressor 110 can receive electrical energy from the outside and compress gaseous refrigerant to high temperature and pressure using rotational force such as an electric motor. The compressor 110 is connected to the condenser 120 and may be provided to move compressed refrigerant to the condenser 120. The compressor 110 may be located inside the machine room 100.

The compressor 110 compresses the refrigerant and pushes it to the condenser, thereby operating a refrigeration cycle of compression, condensation, expansion, and evaporation. Accordingly, when the compressor 110 operates, cold air generated in the evaporator is supplied to the storage compartment 20.

The condenser 120 condenses the high-temperature, high-pressure refrigerant compressed from the compressor 110. The condenser 120 dissipates heat generated while condensing the refrigerant. The refrigerant condensed while passing through the condenser 60 is moved to the expansion valve.

The refrigerant condensed in the condenser 120 passes through the expansion valve and becomes a low-temperature, low-pressure liquid. The liquid refrigerant passes through the expansion valve and moves to the evaporator.

The evaporator evaporates the low-temperature, low-pressure liquid refrigerant that has passed through the expansion valve. The evaporator exchanges heat with the surrounding gas as the liquid refrigerant evaporates. As the liquid refrigerant evaporates, it absorbs latent heat from the main surface, which cools the gas around the evaporator and generates cold air. The completely evaporated refrigerant is supplied back to the compressor 110 and the cooling cycle continues.

Some configurations of the cold air generating unit may be located inside the machine room 100. According to one embodiment of the present invention, the compressor 110, the condenser 120, and the heat dissipation fan 130 may be located inside the machine room 100.

The condenser 120 may include a heat exchange unit. At least a portion of the heat exchanger may be provided at a position corresponding to the second inlet hole 105b so that the heat exchanger can exchange heat with air flowing in through the second inlet hole 105b of the front cover 104.

The condenser 120 according to this illustration is provided to be bent and extended along the area inside the machine room 100, and a condenser ( 120) has been formed, but is not limited to this.

In order for heat exchange to occur efficiently with the air introduced through the second inlet hole 105b provided on the side of the condenser unit 102, the condenser 120 must be provided corresponding to the length of the second inlet hole 105b. In order to increase the contact surface area with air, at least a portion of the condenser 120 may be bent.

In addition, the air flowing in from the second inlet hole 105b is discharged through the second discharge hole 107b provided in the rear cover 106 in the same inflow direction, so the air is discharged from one end of the second inlet hole 105b. It may be formed in a diagonal shape extending to the other end of the hole 107b. As long as heat can be exchanged with the air flowing in from the second inlet hole 105b, it can be provided in various shapes, such as a substantially straight shape or a V-shape.

Referring to FIG. 5, the air circulation process for heat dissipation in the machine room will be described.

As the refrigerant passes through the compressor 110 and the condenser 120, heat is generated in the compressor 110 and the condenser 120, and the heat dissipation fan 130 may operate to dissipate the heat. The compressor fan 131 provided in the compressor unit 101 flows air into the compressor unit 101 to dissipate heat in the compressor 110.

Air flowing into the compressor unit 101 through the first inlet hole 105a may be discharged through the first discharge hole 107a formed in the rear cover 106. Since the air introduced into the compressor unit 101 does not pass through the condenser unit 102 and flows only within the compressor unit 101, air at room temperature can be introduced.

If the air flowing into the compressor unit 101 passes through the condenser unit 102 and then flows in, the air whose temperature increases while dissipating heat in the condenser 120 flows into the compressor unit 101. As the temperature of the gas increases, the mass of the gas corresponding to the same volume decreases, so a smaller mass of air is introduced, and the heat dissipation efficiency of the compressor 110 decreases. Additionally, as relatively low-temperature air is introduced, the temperature difference between the temperature of the compressor 110 and the incoming air increases, and the amount of heat that can be dissipated may also increase.

As the blocking wall 140 physically blocks the compressor unit 101 and the condenser unit 102, room temperature air, which is relatively low temperature air, flows into the compressor unit 101, thereby increasing heat dissipation efficiency. .

When air passing through the condenser unit 102 flows into the compressor unit 101, the flow path length increases and flow resistance due to the condenser 120 and compressor 110 also increases, which may reduce heat exchange efficiency. However, by providing the heat dissipation fan 130 in each of the compressor unit 101 and the condenser unit 102, the compressor 110 dissipates heat by the compressor fan 131 and the condenser 120 also dissipates heat by the condenser fan 132. By dissipating heat, the channel length is shortened, flow resistance is reduced, and heat exchange efficiency can be increased.

Heat exchange efficiency can also be increased by dividing the compressor unit 101 and the condenser unit 102 by the blocking wall 140 and forming a heat dissipation flow for each air.

Accordingly, the heat dissipation efficiency and heat exchange efficiency of the machine room 100 can be increased by the blocking wall 140, and further, the power consumption of the refrigerator 1 can be reduced to increase energy efficiency.

Figure 6 is a side cross-sectional view of the machine room. In FIG. 6 of FIG. 7 , the flow of air is shown by arrows.

Referring to FIGS. 6 and 7 , the base cover 103 may be provided to cover the lower part of the machine room 100.

An inlet hole (not shown) may be additionally provided in the base cover 103.

The front cover 104 may be formed to be inclined upward to form an angle of 0 to 90 degrees from the front end 103b of the base cover 103. The front cover 104 can prevent trash from entering the machine room 100 and impeding the flow of air or harmful animals from entering the machine room 100 and damaging parts of the machine room 100. The front cover 104 may extend to contact the casing portion 15 and may be formed to cover at least a portion between the base cover 103 and the casing portion 15.

The rear cover 106 may include an exhaust hole 107. The discharge hole 107 may include a first discharge hole 107a formed in the compressor unit 101 and a second discharge hole 107b formed in the condenser unit 102.

The heat dissipation fan 130 may be provided between the rear cover 106, the compressor 110, and the condenser 120. The heat dissipation fan 130 may introduce air from the inlet hole 105 of the front cover 104. The heat dissipation fan 130 may dissipate heat from the compressor 110 and the condenser 120 by introducing air. The heat dissipation fan 130 can discharge air that flows into the machine room 100 and undergoes a heat exchange process to the outside through the rear cover 106. It can be discharged to the rear of the refrigerator 1 through the discharge hole 107 formed in the rear cover 106.

The air introduced into the compressor unit 101 and the condenser unit 102 of the machine room 100 may be discharged through the discharge holes 107a and 107b of the rear cover 106, respectively, and the air may be discharged toward the rear upper side.

The louver portion 108 may be provided in a shape that is convex upward. Since the louver portion 108 is provided to be convex upward on the inner upper portion of the discharge holes 107a and 107b, air can be guided to be discharged toward the rear upper side of the refrigerator 1 along the louver portion 108.

The louver portion 108 is provided on the outside of the rear cover 106, but may also be formed on the lower side of the discharge holes 107a and 107b. At this time, the louver portion 108 may be provided in a downward convex shape. Since the louver portion 108 is provided to be convex downward at the outer lower portion of the discharge holes 107a and 107b, air can be discharged toward the rear upper side of the refrigerator along the louver portion 108.

The machine room of a refrigerator according to an embodiment will be described with reference to FIGS. 8 to 12 . Detailed descriptions of the same configuration as the embodiment shown in FIGS. 1 to 7 may be omitted. The heat dissipation fan 230 of the machine room 200 may be a cross-flow fan. The heat dissipation fan 230 may be provided across the compressor unit 201 and the condenser unit 202. The heat dissipation fan 230 can simultaneously flow air in the compressor unit 201 and the condenser unit 202.

The heat dissipation fan 230 may be provided at the rear upper side of the machine room 200. The heat dissipation fan 230 may have a substantially cylindrical shape. The heat dissipation fan 230 may be formed to extend long along the left and right longitudinal directions of the machine room 200. The heat dissipation fan 230 may be disposed in the compressor unit 201 and the condenser unit 202, respectively.

In this illustration, a cross-flow fan formed integrally is shown, but the heat dissipation fan 230 may have a cross-flow fan provided in the compressor unit 201 and an axial fan may be provided in the condenser unit 202. Additionally, an axial fan may be provided in the compressor unit 201 and a transverse flow fan may be provided in the condenser unit 202. Optionally, the heat dissipation fans 230 may be arranged in the same way or differently in the compressor unit 201 and the condenser unit 202.

The rear cover 206 may include an exhaust hole 207 to correspond to the heat dissipation fan 230. When the heat dissipation fan 230 is a cross-flow fan, the discharge hole 207 may be formed with a discharge hole 209 in the form of an opening provided at a position corresponding to the position of the cross-flow fan. When the heat dissipation fan 230 is an axial fan, a plurality of discharge holes 207 may be formed. However, it is not limited to this, and may include both the discharge hole 207 and the discharge port 209.

The discharge hole 207 may include a first discharge hole 207a provided in the compressor unit 201 and a second discharge hole 207b provided in the condenser unit 202.

Since the heat dissipation fan 230 must be located in both the compressor unit 201 and the condenser unit 202, it may be provided to penetrate the barrier wall 240. The blocking wall 240 may include an insertion hole 241 through which the heat dissipation fan 230 is inserted. The insertion hole 241 may be provided in a shape corresponding to the rotation surface of the heat dissipation fan 230. The insertion hole 241 may be formed on the rear upper side of the blocking wall 240, that is, at the corner where the casing portion 15 and the rear cover 206 meet. The insertion hole 241 may be formed in a circular shape because the cross-section of the cross-flow fan is approximately circular. Since the blocking wall 240 must block the air flowing through the compressor unit 201 and the condenser unit 202 from mixing, the insertion hole 241 may be formed to fit the heat dissipation fan 230.

The heat dissipation fan 230 may not have wings on the inside of a portion that contacts the insertion hole 241. The heat dissipation fan 230 may not have a ventilation hole in a portion that contacts the insertion hole 241.

The heat dissipation fan 230 may be provided at the rear upper side of the machine room 100 to discharge air toward the rear upper side of the refrigerator 1. The rear cover 206 may include an outlet 209 through which air is discharged from the heat dissipation fan 230. The discharge port 209 may be formed at a height corresponding to the height at which the heat dissipation fan 230 is located. The discharge port 209 may be formed by cutting a portion of the rear cover 206. The discharge port 209 may be approximately rectangular, but is not limited thereto. Since the heat dissipation fan 230 is provided so that the discharge port 209 extends horizontally, the discharge port 209 may have a rectangular shape that extends horizontally correspondingly. The discharge port 209 may include a first discharge port 207a formed on the compressor unit 201 side and a second discharge port 207b formed on the condenser unit 202 side.

A louver portion 208 may be formed in the discharge hole 207 as shown in FIG. 7 . The louver portion 208 can guide air passing through the discharge hole 207 toward the upper rear side of the refrigerator 1.

A louver portion (not shown) may also be formed in the discharge port 209. The discharge port 209 may include a louver portion to discharge air discharged from the heat dissipation fan 230 toward the rear upper side of the refrigerator 1. The louver portion may be formed by punching the rear cover 206 as shown in FIG. 7, or may be formed by arranging a barb plate.

The heat dissipation fan 230 can simultaneously dissipate heat in the compressor 210 and the condenser 220 by introducing air into the compressor unit 201 and the condenser unit 202, respectively, but the air flowing through each is connected to the barrier wall 240. may not be mixed with each other. Since the heat dissipation fan 230 is configured as a cross-flow fan, there is no need to respectively arrange the heat dissipation fan 230 in the compressor unit 201 and the condenser unit 202.

The heat dissipation fan 230 can introduce air from the front cover 204 to dissipate heat in the compressor 210 and the condenser 220, and then discharge the air through the rear cover 206. Since both the heat dissipation fan 230 and the discharge port 209 are formed on the upper side of the machine room, the discharged air is discharged toward the upper rear side of the refrigerator 1. It is possible to prevent relatively hot air that has radiated heat from the compressor 210 and the condenser 220 from flowing back through the inlet holes 205a and 205b of the front cover 204.
