According to the patent document, a machine room is disposed on one side surface of the refrigerator. Cycle components, including a condenser and compressor, and a cooling duct are disposed in a space adjacent to a storage compartment of the refrigerator. A machine room cover is disposed to cover the inner space 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 disclosure. For example, in the vacuum-insulated refrigerator of the present disclosure, the machine room is positioned below the main body, while the machine room of the patent document is positioned immediately adjacent to the storage compartment of the refrigerator. Therefore, in order to apply the vacuum-insulated refrigerator of the present disclosure, appropriate arrangement of cycle components is required.[Disclosure] [Technical Problem]

[0026] The block may be supported by being disposed so as to be connected to one side of the duct.[Advantageous Effects]

[0027] According to embodiments of the present disclosure, the following effects can be achieved.

[0028] First, the block is disposed between the first space of the main body and the machine room. The block may be formed of a non-vacuum insulator. As an example of the non-vacuum insulator, the block may be formed of polyurethane foam. The block includes a through portion. The through portion forms a passage for a drain pipe through which defrost water generated in the evaporator is drained to the machine room. The through portion 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. The defrost water may pass through the through portion and be drained to the outside. An evaporator accommodating portion in which the evaporator is accommodated includes poor insulation. The insulation reinforcement may be formed to protrude toward the machine room in the block including the through portion through which the drain pipe positioned the lower side of the evaporator passes. Accordingly, the insulation reinforcement may extend the heat transfer path of the through portion, thereby enhancing insulation performance.

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

[0030] Third, a circuit board may be disposed at the front of the machine room. This facilitates easy access for repairs and maintenance of the circuit board and other equipment.

[0031] Fourth, to effectively dissipate heat from the cycle components, airflow in the machine room may be unidirectional. The ducts with the partition wall structures may be installed on both sides of the cycle component. This allows the ducts to isolate the flow path of the air for cooling the condenser and / or compressor from the inner space of the machine room, thereby preventing bypassing the cycle components as much as possible.

[0032] Fifth, the intake port and / or exhaust port 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. The duct may connect the intake port and the exhaust port. The cooling fan may be installed inside the duct to induce the airflow in one direction.

[0033] Sixth, the intake port and / or exhaust port for airflow in the machine room may be disposed on the rear surface of the machine room. By allowing airflow in the machine room to occur on the rear surface 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 may be positioned higher than or equal to the intake port and / or exhaust port, thereby preventing the insulation reinforcement from obstructing the flow of air.

[0035] Eighth, the upper side of the duct is positioned to be in contact with the block, thereby supporting the load at the central portion of the main body.[Description of Drawings]

The cooling fan 117 may exhaust the air that includes passed through the condenser 119 and the compressor 120 to the outside through the exhaust port 1131.

[0114] A plurality of ducts are installed inside the machine room 111. The ducts are effective in directing the air flow direction in one direction. Accordingly, air circulating between an inside and an outside of the machine room 111 is not dispersed, thereby efficiently cooling the condenser 119 and the like. The plurality of ducts include a first duct 121.

[0115] According to the embodiment of FIG. 8, the duct includes the first duct 121. The first duct 121 is configured to isolate the inner space of the machine room 111 and the condenser 119. The first duct 121 may include a partition wall extending in one direction. A plurality of the partition wall may be provided. Among the plurality of partition walls, two partition walls may be disposed to face each other while being spaced apart from each other in the other direction different from the one direction. Another one of the plurality of partition walls is configured to connect one side of each of the two partition walls of the plurality of partition walls. Here, the one direction may be, for example, a left-right direction. The other direction may be, for example, a front-rear direction.

[0116] The partition wall includes a first partition wall 1211 and / or a second partition wall 1212. One side of the first partition wall 1211 may be disposed to be spaced apart from one side of the intake port 1121 by a predetermined distance.

The accommodation space of the condenser 119 is independently isolated from the inner space of the machine room 111 of the condenser 119, thereby improving the efficient heat radiation performance of the condenser 119.

[0118] FIG. 11 is a conceptual diagram illustrating a state where a second duct 222 accommodating the compressor 120 is installed inside the machine room 111 according to another embodiment of the present disclosure.

[0119] FIG. 12 is a conceptual diagram illustrating a state where the length of the first duct 221 is extended in FIG. 11 and the second duct 222 is viewed from various angles. FIG. 12a is a perspective view of the first duct. FIG. 12b is a conceptual diagram illustrating the condenser 119 and cooling fan 117 viewed from one side of the first duct in FIG. 12a. FIG. 12c is a perspective view illustrating the second duct 222 that accommodates the compressor 120. FIG. 12d is a conceptual diagram illustrating the compressor 120 accommodated inside the second duct 222 in FIG. 12c as viewed from the right.

[0120] The present 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 inner 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 disposed to face each other while being spaced apart from each other in the other direction different from 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-rear direction.

[0121] The partition wall includes a first partition wall 2221 and / or a second partition wall 2222. A portion of the first partition wall 2221 may be disposed to face the first insulation reinforcement 1058 accommodated in the machine room 111. One side of the first partition wall 2221 may be disposed to be in contact with one side of the exhaust port 1131 or to be spaced apart from the one side at a preset interval. In the present embodiment, one side of the first partition wall 2221 is illustrated as being disposed to be in contact with one side of the exhaust port 1131. Accordingly, one side of the first partition wall 2221 is in contact with one side of the exhaust port 1131, thereby preventing hot air passing through the condenser 119 and the cooling fan 117 from being dispersed toward the insulation reinforcement, and allowing the hot air to be directly discharged through the exhaust port 1131. Accordingly, it is advantageous to reinforce the weak insulation performance of the evaporator 118.

[0122] The other side of the first partition wall 2221 is connected to the outer periphery of the cooling fan 117. One side of the second partition wall 2222 may be disposed in contact with the other side of the exhaust port 1131 or spaced apart from the other side at a preset interval.

[0124] The third partition wall 2223 is formed to connect one side, for example, the upper side, of each of the first partition wall 2221 and the second partition wall 2222. When one surface of the block 105 is covered to connect one side of the first partition wall 2221 and / or the second partition wall 2222, the third partition wall 2223 may be omitted. Since one surface of the block 105 is in contact with the first partition wall 2221 and / or the second partition wall 2222, the load of the central portion of the main body 100 may be supported.

[0125] Accordingly, the second duct 222 may 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 inner space of the machine room 111 of the compressor 120, so that the compressor 120 can be efficiently cooled.

[0126] The intake port 1121 may be formed in the central portion of one 112 of the plurality of first covers 112 and 113. The exhaust port 1131 may be formed in the central portion of the other 113 of the plurality of first covers 112 and 113.

[0127] 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 the fourth cover is coupled to a refrigeration cycle device accommodated inside the machine room 111.

[0128] The condenser 119 and / or the first duct 221 may be positioned 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 positioned 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.

[0129] The circuit board 223 may be disposed between the third cover 115 and the second duct 222. An electronic component for implementing a controller responsible for overall control of the refrigerator may be coupled to the circuit board 223.

[0130] The circuit board 223 is formed in the shape of a rectangular plate. The circuit board 223 is disposed in one direction (for example, horizontally) on the fourth cover 123. One side of the circuit board 223 is disposed adjacent to the third cover 115. The other side of the circuit board 223 may be disposed to be spaced apart from the second duct 222.

[0131] The third cover 115 is disposed toward the outside of the main body 100. The third cover 115 may form the front surface of the machine room 111. The third cover 115 may be detachably coupled to the front surface of the machine room 111. Accordingly, since the third cover 115 is disposed 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 circuit board 223.

[0132] The first duct 221 may be further extended in one direction. One side of the first duct 221 may be connected to the first covers 112 and 113 so as to surround the intake port 1121 of the first covers 112 and 113. Accordingly, the first duct 221 may prevent air suctioned 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.

[0133] The first duct 221 may further include a first coupling plate. A plurality of the first coupling plates may be provided. At least two of the plurality of first coupling plates may be coupled to the first covers 112 and 113. At least another two of the plurality of first coupling plates may be coupled to the fourth cover 123.

[0135] FIG. 13 is a conceptual diagram illustrating a state where a first duct 321 and a second duct 322 are installed inside the machine room 111 according to still another embodiment of the present disclosure.

[0136] FIG. 14 is a conceptual diagram illustrating the air movement path inside the machine room 111 in FIG. 13.

[0137] FIG. 15 is a conceptual diagram illustrating a state where lengths of the first duct 321 accommodating the condenser 119 and the second duct 322 accommodating the compressor 120 in FIG. 14 are extended, 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 illustrating 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 illustrating the second duct 322 accommodating the compressor 120. FIG. 15d is a conceptual diagram illustrating the compressor 120 accommodated inside the second duct 322 in FIG. 15c as viewed from the right side.

[0138] The present embodiment is different from the embodiment 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 and 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 and 113.

[0139] Accordingly, the first duct 321 may isolate the accommodation space of the condenser 119 from the inner space of the machine room 111, thereby improving the heat radiation performance of the condenser 119. The first duct 321 can prevent a portion of the air suctioned through the intake port 1121 from bypassing the condenser 119.

[0140] The second duct 322 isolates the accommodation space of the compressor 120 from the inner space of the machine room 111, so that the air passing through the condenser 119 can include the effect of cooling the compressor 120. The second duct 322 prevents the heat passing through the compressor 120 from moving to the inner space of the machine room 111, thereby preventing the heat from in another embodiment heating other cycle components.

[0141] Since other components are the same or similar to the embodiment of FIGS. 5 to 12, repeated descriptions will be omitted.

[0142] FIG. 16 is a conceptual diagram illustrating a structure in which air is suctioned and discharged from the rear surface of the machine room 111 according to still another embodiment of the present disclosure.

FIG. 18c is a conceptual diagram illustrating the condenser 119 accommodated in the first duct 421 in FIG. 18a as viewed from above. FIG. 18d is a conceptual diagram illustrating the cooling fan 117 accommodated inside the third duct 423 in FIG. 18a as viewed from the other side.

[0145] The present embodiment differs from the embodiment of FIGS. 5 to 15 in that an intake port 4141 and an exhaust port 4142 are each formed on the same one surface of the machine room 111.

[0146] One surface of the machine room 111 where the intake port 4141 and / or the exhaust port 4142 are formed may be, for example, the rear surface of the machine room 111.

[0147] The intake port 4141 and / or the exhaust port 4142 are formed to penetrate in a first direction on one surface of the machine room 111. The intake port 4141 and the exhaust port 4142 may be disposed to be spaced apart in a second direction different from the first direction.

[0148] The intake port 4141 and / or the exhaust port 4142 may be formed to penetrate the second cover 114 of the machine room 111 in the first direction. The intake port 4141 and the exhaust port 4142 may be disposed spaced apart from each other along the second cover 114. The intake port 4141 may be disposed to be biased toward one side of one 112 of the first covers 112 and 113. The exhaust port 4142 may be disposed to be biased toward one side of the other 113 of the first covers 112 and 113.

[0149] A duct is installed inside the machine room 111. The duct is effective in guiding the air flow direction in one direction. Accordingly, air circulating between an inside and an outside of the machine room 111 is not dispersed, thereby efficiently cooling the condenser 119 and the like. The duct includes the first duct 421. The first duct 421 is configured to accommodate the condenser 119.

[0150] The first duct 421 is configured to isolate the inner space of the machine room 111 from the condenser 119. The first duct 421 may include a partition wall extending in a first direction. A plurality of the partition walls may be provided. The plurality of partition walls may be spaced apart from each other in a second direction and disposed to face each other. Here, for example, the first direction may be the X-axis direction (front-rear direction). The second direction may be the Y-axis direction (left-right direction).

[0151] The partition wall includes a first partition wall 4211 and / or a second partition wall 4212. The first partition wall 4211 extends in the first direction. One side of the first partition wall 4211 is disposed to be in contact with one side of the intake port 4141. The first partition wall 4211 is formed to surround one side of the intake port 4141. The other side of the first partition wall 4211 is connected to one side of the cooling fan 117. The first partition wall 4211 may be disposed close to the exhaust port 4142. The first partition wall 4211 may prevent air suctioned through the intake port 4141 from bypassing the condenser 119 and escaping through the exhaust port 4142.

[0152] The second partition wall 4212 extends in the first direction. One side of the second partition wall 4212 is disposed to be in contact with the other side of the intake port 4141. The second partition wall 4212 is formed to surround the other side of the intake port 4141. The other side of the second partition wall 4212 is connected to one side of the cooling fan 117. The second partition wall 4212 may be disposed close to one side of one 112 of the first covers 112 and 113. The second partition wall 4212 can prevent air suctioned through the intake port 4141 from bypassing the condenser 119 and being dispersed into the inner space of the machine room 111.

[0153] One side of the first partition wall 4211 and / or the second partition wall 4212 is disposed adjacent to the intake port 4141. The other side of the first partition wall 4211 and / or the second partition wall 4212 accommodates a condenser 119. One side and the other side of the first partition wall 4211 and / or the second partition wall 4212 may include 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 partition wall 4212 is lower than that of the other side of the first and second partition walls 4212. This is to ensure that the first partition wall 4211 and / or the second partition wall 4212 is in contact with the block 105, so that the duct can support the load of the main body 100.

[0154] For example, the first insulation reinforcement 1058 of the block 105 disposed on one side of the main body 100 may be disposed to be in contact with one side of the first partition wall 4211 and / or the second partition wall 4212. The length of the first insulation reinforcement 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. Accordingly, the first insulation reinforcement 1058 can be prevented from interfering with the flow of air.

[0155] The third block portion 1057 of the block 105 disposed on one side of the main body 100 can be disposed to be in contact with the other side of the first partition wall 4211 and / or the second partition wall 4212. The third block portion 1057 is disposed to cover an opening formed on the other side of the first partition wall 4211 and / or the second partition wall 4212. Accordingly, the other side of the first partition wall 4211 and / or the second partition wall 4212 may be in contact with the central portion of the block 105 to support the load of the central portion of the main body 100.

[0156] Accordingly, the first duct 421 may 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 inner space of the machine room 111 of the condenser 119, thereby improving the efficient heat radiation performance of the condenser 119.

[0157] The duct includes a second duct 422. The second duct 422 is configured to accommodate the compressor 120.

[0158] The second duct 422 is configured to isolate the inner space of the machine room 111 and the compressor 120. The second duct 422 may include a partition wall extending in a first direction. A plurality of the partition walls may be provided. The plurality of partition walls may be spaced apart from each other in the second direction and disposed to face each other. Here, for example, the first direction may be the X-axis direction (front-rear direction). The second direction may be the Y-axis direction (left-right direction).

[0159] 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 disposed to be in contact with one side of the exhaust port 4142. The first partition wall 4221 is formed to surround one side of the exhaust 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 disposed close to the other 113 of the first covers 112 and 113. The first partition wall 4221 can prevent air to be discharged through the exhaust port 4142 from escaping through the exhaust port 4142 and being dispersed into the inner space of the machine room 111.

[0160] The second partition wall 4222 extends in the first direction. One side of the second partition wall 4222 is disposed to be in contact with the other side of the exhaust port 4142. The second partition wall 4222 is formed to surround the other side of the exhaust port 4142. The other side of the second partition wall 4222 is connected to one side of the cooling fan 117. The second partition wall 4222 may be disposed close to one side of the intake port 4141. The second partition wall 4222 may prevent a portion of the air to be discharged through the exhaust port 4142 from moving to the intake port 4141 and interfering with the air to be suctioned through the intake port 4141.

[0161] One side of the first partition wall 4221 and / or the second partition wall 4222 is disposed adjacent to the exhaust port 4142. The other side of the first partition wall 4221 and / or the second partition wall 4222 accommodates the compressor 120. The one side and the other side of the first partition wall 4221 and / or the second partition wall 4222 may include 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 partition wall 4222 is positioned lower than the other side of the first and second partition walls 4222. This is to ensure that the first partition wall 4221 and / or the second partition wall 4222 comes into contact with the block 105, so that the duct can support the load of the main body 100.

[0162] For example, the first insulation reinforcement 1058 of the block 105 disposed on one side of the main body 100 may be disposed to be in contact with one side of the first partition wall 4221 and / or the second partition wall 4222. The length of the first insulation reinforcement 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 suctioned through the intake port 4141. Accordingly, the first insulation reinforcement 1058 can be prevented from interfering with the flow of air.

[0163] The third block portion 1057 of the block 105 disposed on one side of the main body 100 can be disposed to be in contact with the other side of the first partition wall 4221 and / or the second partition wall 4222 of the second duct 422. The third block portion 1057 is disposed to cover an opening formed on the other side of the first partition wall 4221 and / or the second partition wall 4222. Accordingly, the other side of the first partition wall 4221 and / or the second partition wall 4222 of the second duct 422 may be in contact with the central portion of the block 105 to support the load of the central portion of the main body 100.

[0164] Therefore, the second duct 422 may 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 inner space of the machine room 111 of the condenser 119, thereby improving the efficient heat radiation performance of the condenser 119.

[0165] 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 4231 and 4232 extending in the second direction. One of the plurality of partition walls 4231 and 4232 may be connected to the other side of the first partition wall 4211 of the first duct 421 and the other side of the second partition wall 4222 of the second duct 422. Another of the plurality of partition walls may be connected to the other side of the second partition wall 4212 of the first duct 421 and the other side of the first partition wall 4221 of the second duct 422.

[0166] The third duct 423 is configured to accommodate a cooling fan 117. The cooling fan 117 is disposed 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 inner space of the machine room 111.

[0167] The first duct 421 can allow air suctioned in through the intake port 4141 to flow in a first direction and deliver the air to one side of the third duct 423.
