Cycle components, including a condenser and compressor, and a cooling duct are arranged in a space adjacent to the refrigerator's storage compartment. A machine room cover is arranged to cover the interior of the machine room.

[0004] However, the patent document relates to the arrangement of cycle components, making it difficult to apply to the vacuum-insulated refrigerator of the present invention. For example, the vacuum-insulated refrigerator of the present invention is located below the main body, while the machine room of the patent document is located immediately adjacent to the refrigerator's storage compartment. Therefore, applying the invention to the vacuum-insulated refrigerator of the present invention requires appropriate arrangement of cycle components.

[0010] The fifth objective is to provide a refrigerator having a structure that can minimize interference with cycle parts housed inside the machine room.

[0011] The insulator of the present invention may be provided as at least one insulator. For example, the insulator of the present invention may provide a first wall extending in one direction; and a second wall extending in a direction different from the one direction. As another example, the insulator of the present invention may include a first insulator and a second insulator. The second insulator may be provided as a separate component separated from the first insulator. The second insulator may be connected to the first insulator by a connecting member. In the present invention, the connecting member may be defined as a joint. The second insulator may include a portion extending in the same direction as the first insulator.

[0012] According to one embodiment of the present invention, a refrigerator includes a main body forming an exterior of the refrigerator.

The first duct and / or the second duct may be disposed in a central portion between the second cover and the third cover.

[0021] An intake port may be formed in one of the plurality of first covers forming the first surface of the machine room. An exhaust port may be formed in another of the plurality of first covers forming the second surface of the machine room.

[0022] The duct may be open at one side and the other side of the unidirectional duct to allow the flow of air in one direction, and / or may include at least one baffle surrounding the condenser and the compressor to isolate the condenser and the compressor from the interior space of the machine room. At least three baffles may be provided.

[0023] Optionally, an inlet and an outlet may be formed to penetrate through one surface of the machine room in a first direction. The inlet and the outlet may be arranged to be spaced apart from the first direction in a second direction on one surface of the machine room.

[0026] The above block can be supported by being positioned so as to be connected to one side of the above duct.

[0027] According to an embodiment of the present invention, the following effects can be achieved.

[0028] First, a block is placed between the first space of the main body and the machine room. The block may be composed of a non-vacuum insulator. As an example of the non-vacuum insulator, the block may be composed of polyurethane foam. The block includes a penetration. The penetration forms a passage for a drain pipe through which defrost water generated in the evaporator is drained to the machine room. The penetration is formed on one side of the evaporator. Here, one side of the evaporator may refer to the lower side of the evaporator as an example. Defrost water may pass through the penetration and be drained to the outside. The evaporator housing, where the evaporator is housed, has poor insulation. An insulation reinforcement portion may be formed to protrude toward the machine room in the block including the penetration portion through which a drain pipe for the lower side of the evaporator passes. Through this, the insulation reinforcement portion can extend the heat transfer path of the penetration portion, thereby enhancing insulation performance.

[0029] Second, cycle components, such as condensers and / or compressors, should be positioned to avoid interference with the insulation reinforcement of blocks protruding into the machine room. For example, the insulation reinforcement may protrude toward the rear of the machine room. Cycle components may be located in the center of the machine room, rather than at the front. This minimizes the transmission of cooling fan noise for the compressor or condenser to the front of the machine room when cycle components are located in the center of the machine room.

[0030] Third, printed circuit boards can be placed at the front of the machine room. This facilitates easy access for repairs and maintenance of printed circuit boards and other equipment.

[0031] Fourth, to effectively dissipate heat from the cycle components, airflow in the machine room can be unidirectional. Ducts with baffle structures can be installed on both sides of the cycle components. This allows the ducts to isolate the airflow for cooling the condenser and / or compressor from the internal space of the machine room, thereby preventing bypassing the cycle components as much as possible.

[0032] Fifth, intake and / or exhaust ports for airflow in the machine room may be formed on a plurality of first covers facing each other in one direction within the machine room. Ducts may connect the intake and exhaust ports. A cooling fan may be installed within the duct to induce airflow in one direction.

[0033] Sixth, the intake and / or exhaust ports for airflow in the machine room may be located at the rear of the machine room. By allowing airflow in the machine room to occur at the rear of the machine room, hot air passing through the condenser can be prevented from moving to the front of the machine room.

[0034] Seventh, the insulation reinforcement protruding from the lower side of the block can be positioned higher than or equal to the intake and / or exhaust ports, thereby preventing the insulation reinforcement from obstructing the flow of air.

[0035] Eighth, the upper part of the duct is positioned to be in contact with the block, so that it can support the load at the center of the main body.

[0136] The machine room (111) is configured to accommodate parts of the refrigeration cycle device, such as a compressor (120), a condenser (119), an expander, etc.

[0137] A condenser (119) is arranged on one side of the machine room (111). A compressor (120) is arranged on the other side of the machine room (111). The condenser (119) and the compressor (120) are arranged to be spaced apart from each other in one direction. A cooling fan (117) is arranged between the condenser (119) and the compressor (120). The cooling fan (117) is configured to cool the condenser (119) by using air flow. The cooling fan (117) is configured to cause air to flow in one direction within the machine room (111). The air flow of the cooling fan (117) can correspond to the arrangement direction of the condenser (119) and the compressor (120).

[0138] The condenser (119) may be placed adjacent to one (112) of the plurality of first covers (112, 113) within the machine room (111). The compressor (120) may be placed adjacent to another (113) of the plurality of first covers (112, 113) within the machine room (111).

[0139] A suction port (1121) may be formed to penetrate one (112) of the plurality of first covers (112, 113) in one direction. The suction port (1121) includes a plurality of holes that are thin and extend long in one direction. The plurality of holes may be arranged to be spaced apart from each other at a preset interval in the one direction or in a direction other than the one direction. Here, an example of one direction may be the Z-axis direction. An example of the other direction may be the X-axis direction.

[0140] A discharge port (1131) may be formed to penetrate one of the plurality of first covers (112, 113) in one direction. The discharge port (1131) includes a plurality of holes that are thin and extend long in one direction. The plurality of holes may be arranged to be spaced apart from each other at a preset interval in the one direction or in a direction other than the one direction. Here, an example of one direction may be the Z-axis direction. An example of the other direction may be the X-axis direction.

[0141] The cooling fan (117) has a plurality of blades rotatably installed inside the fan casing to guide the air flow direction in one direction. The cooling fan (117) can take in external air through the intake port (1121). The cooling fan (117) can guide the air flow direction to the condenser (119). The cooling fan (117) can guide the air flow direction to the compressor (120). The cooling fan (117) can exhaust the air that has passed through the condenser (119) and the compressor (120) to the outside through the discharge port (1131).

[0142] A plurality of ducts are installed inside the machine room (111). The ducts are effective in directing the air flow direction in one direction. This allows the air circulating inside and outside the machine room (111) to be efficiently cooled, such as the condenser (119), without being dispersed. The plurality of ducts include a first duct (121).

[0143] According to the embodiment of FIG. 8, the duct includes a first duct (121). The first duct (121) is configured to isolate the internal space of the machine room (111) and the condenser (119). The first duct (121) may include a partition wall extending in one direction. The partition wall may be provided in plurality. Two of the plurality of partition walls may be spaced apart from the one direction and the other direction and may be arranged to face each other. The other of the plurality of partition walls is configured to connect one side of the two partition walls among the plurality of partition walls. Here, an example of the one direction may be a left-right direction. An example of the other direction may be a front-back direction.

[0144] The bulkhead includes a first bulkhead (1211) and / or a second bulkhead (1212). One side of the first bulkhead (1211) may be arranged to be spaced apart from one side of the intake port (1121) by a predetermined distance. The other side of the first bulkhead (1211) is connected to the outer periphery of the cooling fan (117). One side of the second bulkhead (1212) may be connected to the other side of the intake port (1121) by a predetermined distance. The other side of the second bulkhead (1212) may be connected to the outer periphery of the cooling fan (117). The third bulkhead is configured to connect one side of each of the first bulkhead (1211) and the second bulkhead (1212).

[0145] Through this, the first duct (121) can accommodate the condenser (119) and induce the air flow direction in one direction. The accommodation space of the condenser (119) is independently isolated from the internal space of the machine room (111) of the condenser (119), thereby improving the efficient heat dissipation performance of the condenser (119).

[0146] FIG. 11 is a conceptual diagram showing a second duct (222) accommodating a compressor (120) according to another embodiment of the present invention installed inside a machine room (111).

[0147] Fig. 12 is a conceptual diagram showing the extension of the first duct (221) in Fig. 11 and the second duct (222) viewed from various angles. Fig. 12a is a perspective view of the first duct (221). Fig. 12b is a conceptual diagram showing the condenser (119) and the cooling fan (117) viewed from one side of the first duct (221) in Fig. 12a. Fig. 12c is a perspective view showing the second duct (222) accommodating the compressor (120). Fig. 12d is a conceptual diagram showing the compressor (120) accommodated inside the second duct (222) in Fig. 12c viewed from the right side.

[0148] This embodiment differs from the embodiment of FIG. 8 described above in that the duct further includes a second duct (222). The second duct (222) may be configured to isolate the compressor (120) from the interior space of the machine room (111). The second duct (222) may include a plurality of partition walls extending in one direction. The plurality of partition walls may be spaced apart from the one direction and arranged to face each other in a direction other than the one direction. Here, an example of the one direction may be the left-right direction. An example of the other direction may be the front-back direction.

[0149] The bulkhead includes a first bulkhead (2221) and / or a second bulkhead (2222). A portion of the first bulkhead (2221) may be arranged to face the first insulation reinforcement member (1058) accommodated in the machine room (111). One side of the first bulkhead (2221) may be arranged to be in contact with one side of the discharge port (1131) or to be spaced apart from it at a preset interval. In the present embodiment, one side of the first bulkhead (2221) is shown arranged to be in contact with one side of the discharge port (1131). Through this, one side of the first bulkhead (2221) is in contact with one side of the discharge port (1131), thereby preventing hot air passing through the condenser (119) and the cooling fan (117) from being dispersed toward the insulation reinforcement member, and allowing the hot air to be directly discharged through the discharge port (1131). Accordingly, it is advantageous to reinforce the weak insulation performance of the evaporator (118).

[0150] The other side of the first bulkhead (2221) is connected to the outer periphery of the cooling fan (117). One side of the second bulkhead (2222) may be arranged in contact with the other side of the discharge port (1131) or spaced apart from it at a preset interval. The other side of the second bulkhead (2222) may be connected to the outer periphery of the cooling fan (117).

[0151] The second bulkhead (2222) is positioned on the opposite side of the first bulkhead (2221) with the compressor (120) between them. A printed circuit board (223) may be positioned between the second bulkhead (2222) and the third cover (115).

[0152] The third bulkhead (2223) is formed to connect one side, for example, the upper side, of each of the first bulkhead (2221) and the second bulkhead (2222). If one side of the block (105) is covered to connect one side of the first bulkhead (2221) and / or the second bulkhead (2222), the third bulkhead (2223) may be omitted. Since one side of the block (105) is in contact with the first bulkhead (2221) and / or the second bulkhead (2222), the load of the central portion of the main body (100) can be supported.

[0153] Through this, the second duct (222) can accommodate the compressor (120) and induce the air flow direction in one direction. The accommodation space of the compressor (120) is independently isolated from the internal space of the machine room (111) of the compressor (120), so that the compressor (120) can be efficiently cooled.

[0154] The suction port (1121) may be formed in the central portion of one (112) of the plurality of first covers (112, 113). The discharge port (1131) may be formed in the central portion of another (113) of the plurality of first covers (112, 113).

[0155] The condenser (119) and / or the compressor (120) are coupled to the fourth cover (123). The fourth cover (123) may be referred to as a base cover in that it is coupled to a refrigeration cycle device housed inside the machine room (111).

[0156] The condenser (119) and / or the first duct (221) may be located at a central portion between the second cover (114) and the third cover (115). The compressor (120) and / or the second duct (222) may be located at a central portion between the second cover (114) and the third cover (115). The distance between the condenser (119) and the first duct (221) and the second cover (114) may be the same as the distance between the condenser (119) and the first duct (221) and the third cover (115). The distance between the compressor (120) and / or the second duct (222) and the second cover (114) may be the same as the distance between the compressor (120) and the second duct (222) and the third cover (115).

[0157] A printed circuit board (223) may be placed between the third cover (115) and the second duct (222). Electronic components for implementing a control unit responsible for overall control of the refrigerator may be combined with the printed circuit board (223).

[0158] The printed circuit board (223) is formed in the shape of a rectangular plate. The printed circuit board (223) is arranged in one direction (e.g., horizontally) on the fourth cover (123). One side of the printed circuit board (223) is arranged adjacent to the third cover (115). The other side of the printed circuit board (223) may be arranged to be spaced apart from the second duct (222).

[0159] The third cover (115) is positioned toward the outside of the main body (100). The third cover (115) can form the front of the machine room (111). The third cover (115) can be detachably coupled to the front of the machine room (111). Accordingly, since the third cover (115) is positioned at the front of the machine room (111), there is an advantage in that it is easy for a worker to perform maintenance, such as repairing a malfunction of the printed circuit board (223).

[0160] The first duct (221) may be further extended in one direction. One side of the first duct (221) may be connected to the first cover (112, 113) so as to surround the intake port (1121) of the first cover (112, 113). In this way, the first duct (221) may prevent air sucked into the interior of the machine room (111) through the intake port (1121) from being dispersed from the interior of the first duct (221) to the exterior.

[0161] The first duct (221) may further include a first coupling plate. The first coupling plates may be provided in multiple numbers. At least two of the plurality of first coupling plates may be coupled to the first cover (112, 113). At least two other of the plurality of first coupling plates may be coupled to the fourth cover (123).

[0162] The second duct (222) may further include two connecting plates. The second connecting plates may be provided in multiple numbers. At least two of the multiple second connecting plates (2224) may be connected to the fourth cover (123).

[0163] Fig. 13 is a conceptual diagram showing the first duct (321) and the second duct (322) installed inside the machine room (111) according to another embodiment of the present invention.

[0164] Figure 14 is a conceptual diagram showing the air movement path inside the machine room (111) in Figure 13.

[0165] FIG. 15 is a conceptual diagram showing the first duct (321) accommodating the condenser (119) and the second duct (322) accommodating the compressor (120) in FIG. 14 being extended in length, and the first duct (321) and the second duct (322) viewed from various angles. FIG. 15a is a perspective view of the first duct (321). FIG. 15b is a conceptual diagram showing the condenser (119) and the cooling fan (117) viewed from one side of the first duct (321) in FIG. 15a. FIG. 15c is a perspective view showing the second duct (322) accommodating the compressor (120). FIG. 15d is a conceptual diagram showing the compressor (120) accommodated inside the second duct (322) in FIG. 15c as viewed from the right side.

[0166] This embodiment is different from the embodiments of FIGS. 1 to 12 described above in that one side of the first duct (321) is coupled to seal and surround the intake port (1121) of one (112) of the first covers (112, 113), and the other side of the second duct (322) is coupled to seal and surround the exhaust port (1131) of the other (113) of the first covers (112, 113).

[0167] Through this, the first duct (321) can isolate the receiving space of the condenser (119) from the internal space of the machine room (111), thereby improving the heat dissipation performance of the condenser (119). The first duct (321) can prevent a portion of the air sucked in through the intake port (1121) from bypassing the condenser (119).

[0168] The second duct (322) isolates the receiving space of the compressor (120) from the internal space of the machine room (111), so that the air passing through the condenser (119) can have the effect of cooling the compressor (120). The second duct (322) prevents the heat passing through the compressor (120) from moving to the internal space of the machine room (111), thereby preventing the heat from additionally heating other cycle components.

[0169] Since other components are the same or similar to the embodiments of FIGS. 5 to 12, redundant descriptions will be omitted.

[0170] Fig. 16 is a conceptual diagram showing a structure in which air is sucked in and discharged from the rear of a machine room (111) according to another embodiment of the present invention.

[0171] Figure 17 is a conceptual diagram showing a top view of the machine room (111) in Figure 16.

[0172] Fig. 18a is a conceptual diagram showing a combined appearance of the first duct (421) accommodating the condenser (119) and / or the third duct (423) accommodating the cooling fan (117) in Fig. 17. Fig. 18b is a conceptual diagram showing a rear-view view of the condenser (119) accommodated inside the first duct (421) in Fig. 18a. Fig. 18c is a conceptual diagram showing a top-view view of the condenser (119) accommodated in the first duct (421) in Fig. 18a. Fig. 18d is a conceptual diagram showing a cooling fan (117) accommodated inside the third duct (423) in Fig. 18a, as seen from the other side.

[0173] This embodiment differs from the embodiments of FIGS. 5 to 15 in that the suction port (4141) and the discharge port (4142) are each formed on the same side of the machine room (111).

[0174] One side of the machine room (111) where the intake port (4141) and / or the exhaust port (4142) are formed may be, for example, the rear side of the machine room (111).

[0175] The suction port (4141) and / or the discharge port (4142) are formed to penetrate in a first direction on one side of the machine room (111). The suction port (4141) and the discharge port (4142) may be arranged to be spaced apart from the first direction in a second direction.

[0176] The suction port (4141) and / or the discharge port (4142) may be formed to penetrate the second cover (114) of the machine room (111) in the first direction. The suction port (4141) and the discharge port (4142) may be spaced apart from each other along the second cover (114). The suction port (4141) may be arranged to be biased toward one side of one (112) of the first covers (112, 113). The discharge port (4142) may be arranged to be biased toward one side of the other (113) of the first covers (112, 113).

[0177] A duct is installed inside the machine room (111). The duct is effective in directing the air flow direction in one direction. This allows the air circulating inside and outside the machine room (111) to be efficiently cooled, such as the condenser (119), without being dispersed. The duct includes a first duct (421). The first duct (421) is configured to accommodate the condenser (119).

[0178] The first duct (421) is configured to isolate the internal space of the machine room (111) and the condenser (119). The first duct (421) may include a partition wall extending in a first direction. The partition wall may be provided in multiple numbers. The multiple partition walls may be spaced apart from each other in a second direction and arranged to face each other. Here, an example of the first direction may be the X-axis direction (front-back direction). The second direction may be the Y-axis direction (left-right direction).

[0179] The bulkhead includes a first bulkhead (4211) and / or a second bulkhead (4212). The first bulkhead (4211) extends in the first direction. One side of the first bulkhead (4211) is arranged to be in contact with one side of the intake port (4141). The first bulkhead (4211) is formed to surround one side of the intake port (4141). The other side of the first bulkhead (4211) is connected to one side of the cooling fan (117). The first bulkhead (4211) may be arranged close to the discharge port (4142). The first bulkhead (4211) may prevent air sucked through the intake port (4141) from bypassing the condenser (119) and escaping through the discharge port (4142).

[0180] The second bulkhead (4212) extends in the first direction. One side of the second bulkhead (4212) is arranged to be in contact with the other side of the intake port (4141). The second bulkhead (4212) is formed to surround the other side of the intake port (4141). The other side of the second bulkhead (4212) is connected to one side of the cooling fan (117). The second bulkhead (4212) may be arranged close to one side of one (112) of the first covers (112, 113). The second bulkhead (4212) can prevent air sucked through the intake port (4141) from bypassing the condenser (119) and being dispersed into the internal space of the machine room (111).

[0181] One side of the first bulkhead (4211) and / or the second bulkhead (4212) is arranged adjacent to the intake port (4141). The other side of the first bulkhead (4211) and / or the second bulkhead (4212) accommodates a condenser (119). One side and the other side of the first bulkhead (4211) and / or the second bulkhead (4212) may have different heights extending in the Z-axis direction from the fourth cover (123). The height of one side of the first and / or the second bulkhead (4212) is positioned lower than the other side of the first and second bulkheads (4212). This is to ensure that the first bulkhead (4211) and / or the second bulkhead (4212) is in contact with the block (105), so that the duct can support the load of the main body (100).

[0182] For example, the first insulation reinforcement part (1058) of the block (105) arranged on one side of the main body (100) can be arranged to be in contact with one side of the first bulkhead (4211) and / or the second bulkhead (4212). The length of the first insulation reinforcement part (1058) protruding toward the machine room (111) is formed on the upper side of the intake port (4141) so as not to block the flow of air sucked through the intake port (4141). Through this, the first insulation reinforcement part (1058) can be prevented from interfering with the flow of air.

[0183] The third block portion (1057) of the block (105) arranged on one side of the main body (100) can be arranged to be in contact with the other side of the first bulkhead (4211) and / or the second bulkhead (4212). The third block portion (1057) is arranged to cover an opening formed on the other side of the first bulkhead (4211) and / or the second bulkhead (4212). Through this, the other side of the first bulkhead (4211) and / or the second bulkhead (4212) can be in contact with the central portion of the block (105) to support the load of the central portion of the main body (100).

[0184] Through this, the first duct (421) can accommodate the condenser (119) and induce the air flow direction in one direction. The accommodation space of the condenser (119) is independently isolated from the internal space of the machine room (111) of the condenser (119), thereby improving the efficient heat dissipation performance of the condenser (119).

[0185] The duct includes a second duct (422). The second duct (422) is configured to accommodate a compressor (120).

[0186] The second duct (422) is configured to isolate the internal space of the machine room (111) and the compressor (120). The second duct (422) may include a partition wall extending in a first direction. The partition wall may be provided in multiple numbers. The multiple partition walls may be spaced apart from each other in the second direction and arranged to face each other. Here, an example of the first direction may be the X-axis direction (front-back direction). The second direction may be the Y-axis direction (left-right direction).

[0187] The partition wall includes a first partition wall (4221) and / or a second partition wall (4222). The first partition wall (4221) extends in the first direction. One side of the first partition wall (4221) is arranged to be in contact with one side of the discharge port (4142). The first partition wall (4221) is formed to surround one side of the discharge port (4142). The other side of the first partition wall (4221) is connected to the other side of the cooling fan (117). The first partition wall (4221) may be arranged close to the other one (113) of the first covers (112, 113). The first partition wall (4221) can prevent air to be discharged through the discharge port (4142) from escaping through the discharge port (4142) and being dispersed into the internal space of the machine room (111).

[0188] The second bulkhead (4222) extends in the first direction. One side of the second bulkhead (4222) is arranged to be in contact with the other side of the discharge port (4142). The second bulkhead (4222) is formed to surround the other side of the discharge port (4142). The other side of the second bulkhead (4222) is connected to one side of the cooling fan (117). The second bulkhead (4222) may be arranged close to one side of the intake port (4141). The second bulkhead (4222) may prevent a portion of the air to be discharged through the discharge port (4142) from moving to the intake port (4141) and interfering with the air to be sucked through the intake port (4141).

[0189] One side of the first bulkhead (4221) and / or the second bulkhead (4222) is arranged adjacent to the discharge port (4142). The other side of the first bulkhead (4221) and / or the second bulkhead (4222) accommodates the compressor (120). The one side and the other side of the first bulkhead (4221) and / or the second bulkhead (4222) may have different heights extending in the Z-axis direction from the fourth cover (123). The height of one side of the first and / or the second bulkhead (4222) is positioned lower than the other side of the first and second bulkheads (4222). This is to ensure that the first bulkhead (4221) and / or the second bulkhead (4222) comes into contact with the block (105), so that the duct can support the load of the main body (100).

[0190] For example, the first insulation reinforcement part (1058) of the block (105) arranged on one side of the main body (100) can be arranged to be in contact with one side of the first bulkhead (4221) and / or the second bulkhead (4222). The length of the first insulation reinforcement part (1058) protruding toward the machine room (111) is formed on the upper side of the intake port (4141) so as not to block the flow of air sucked through the intake port (4141). Through this, the first insulation reinforcement part (1058) can be prevented from interfering with the flow of air.

[0191] The third block portion (1057) of the block (105) arranged on one side of the main body (100) can be arranged to be in contact with the other side of the first bulkhead (4221) and / or the second bulkhead (4222) of the second duct (422). The third block portion (1057) is arranged to cover an opening formed on the other side of the first bulkhead (4221) and / or the second bulkhead (4222). Through this, the other side of the first bulkhead (4221) and / or the second bulkhead (4222) of the second duct (422) can be in contact with the central portion of the block (105) to support the load of the central portion of the main body (100).

[0192] Through this, the second duct (422) can accommodate the compressor (120) and induce the air flow direction in one direction. The accommodation space of the condenser (119) is independently isolated from the internal space of the machine room (111) of the condenser (119), thereby improving the efficient heat dissipation performance of the condenser (119).

[0193] The duct may further include a third duct (423). The third duct (423) is configured to connect the other side of the first duct (421) and the other side of the second duct (422). The third duct (423) includes a plurality of partition walls extending in the second direction. One of the plurality of partition walls may be connected to the other side of the first partition wall (4231) of the first duct (421) and the other side of the second partition wall (4232) of the second duct (422). Another of the plurality of partition walls may be connected to the other side of the second partition wall (4232) of the first duct (421) and the other side of the first partition wall (4231) of the second duct (422).

[0194] The third duct (423) is configured to accommodate a cooling fan (117). The cooling fan (117) is positioned between the condenser (119) and the compressor (120). The cooling fan (117) forms a flow of air. The third duct (423) is configured to isolate the accommodation space of the cooling fan (117) from the internal space of the machine room (111).

[0195] The first duct (421) can allow air sucked in through the intake port (4141) to flow in a first direction and deliver it to one side of the third duct (423). The third duct (423) can convert the air sucked in in the first direction into a second direction and deliver it to the other side of the second duct (422). The second duct (422) can cause the air that has passed through the compressor (120) to U-turn in a direction opposite to the first direction and discharge it to the outside of the machine room (111) through the discharge port (4142).
