[0001] This specification relates to a refrigerator.

[0002] A refrigerator is a home appliance that keeps food at a low temperature in an internal storage compartment enclosed by a door.

[0003] The above storage room is surrounded by an insulating wall so that the inside of the storage room is maintained at a temperature lower than the outside temperature. Depending on the temperature range of the storage room, the storage room may be referred to as a refrigerator or a freezer.

[0004] The above refrigerator includes a machine room, and the machine room may be provided with a part of a cooling unit that operates to cool the storage room.

[0005] The above cooling unit may include a compressor, a condenser, a blower fan located within the machine room, and an evaporator located outside the machine room.

[0006] During the operation of the above cooling unit, the temperature of the air exchanged with the condenser rises. The efficiency of the condenser and compressor can be improved only when the high-temperature air is smoothly discharged from the machine room.

[0143] The above plate assembly (40) may further include a barrier (60). The barrier (60) may restrict air sucked into the air intake port (401) from flowing directly to the air outlet port (403).

[0144] The above barrier (60) may overlap with the fan housing (540) in the Y-axis direction. The barrier (60) may be provided with a sealing member (65). The sealing member (65) may be in contact with the front plate (480). Therefore, the air sucked into the air intake port (401) may be restricted from flowing between the barrier (60) and the front plate (480).

[0169] The second part (484) can connect the first part (482) and the third part (486) with different heights. The second part (484) can have the same slope as a whole or can include two sections (484a, 484b) with different slopes.

[0170] The sum (L2) of the Y-axis direction lengths of the second part (484) and the third part (486) may be greater than the Y-axis direction length (L1) of the first part (482).

[0171] The second part (484) can overlap with the barrier (60) in the Z-axis direction. The second part (484) can come into contact with the sealing member (65).

The condenser (560) may be positioned adjacent to the air intake (401). The blower fan (530) may be positioned between the compressor (510) and the condenser (560).

[0176] The condenser (560) may be positioned adjacent to the first side plate (440). The compressor (510) may be positioned adjacent to the second side plate (450).

[0177] The condenser (560) may include a first portion (562). The first portion (562) may be positioned closer to the air intake (401) than the rear plate (430).

[0178] The above condenser (560) may further include a second part (562). The first part (562) and the second part (564) may be arranged in the Y-axis direction.

[0179] The second part (564) may be positioned between the first part (562) and the rear plate (430).

[0180] The condenser (560) may further include a third portion (566). The third portion (566) may connect the first portion (562) and the second portion (564). The third portion (566) may include a portion facing the first side plate (440).

[0181] In the present embodiment, the condenser (560) may include a tube (560a) including a plurality of refrigerant channels, and headers (560b, 560c) connected to the tubes (560a). The plurality of tubes may be arranged in the Z-axis direction. The plurality of tubes (560a) may be connected to the headers (560b, 560c).

[0182] The above headers (560b, 560c) may include a first header (560b) connected to the first part (562) and a second header (560c) connected to the second part (564).

[0183] The condenser (560) may have, for example, a shape like "⊂". Depending on the case, the arrangement of the condenser (560) may vary. For example, the condenser (560) may be arranged in a shape like "⊃", the condenser (560) may be arranged in a shape like "∪", or the condenser (560) may be arranged in a shape like "∩".

[0184] As another example, it is also possible for the condenser (560) to have a shape like "┗". For example, it is also possible for the condenser (560) to include only the first part (562) and the third part (566) in FIG. 8 ("┗" shape). Alternatively, it is also possible for the condenser (560) to include only the first part (562) and the third part (566) in FIG. 8, but for the third part (566) to be positioned adjacent to the blower fan (530) ("┛" shape).

[0185] Alternatively, the condenser (560) may include only the second part (564) and the third part (566) (in the form of "┏"). However, in this case, the shape or position of the second part (564) or the third part (566) may be changed so as to secure heat exchange performance. Alternatively, the condenser (560) may include only the second part (564) and the third part (566) in FIG. 8, but the third part (566) may be positioned adjacent to the blower fan (530) (in the form of "┓"). However, in this case, the shape or position of the second part (564) or the third part (566) may be changed so as to secure heat exchange performance.

[0186] Alternatively, the condenser (560) may be a general fin tube type condenser. That is, in the present embodiment, there is no limitation on the shape of the condenser (560), and it is to be noted that various shapes of condensers can be applied.

[0187] The fan housing (540) may overlap with the barrier (60) in the Y-axis direction. A sealing member (550) may be provided on the outside of the fan housing (540). The sealing member (550) may restrict air sucked into the air intake port (401) from flowing between the fan housing (540) and the front plate (480).

[0188] The above machine room (30) may be equipped with a flow restriction member (590). The flow restriction member (590) may be positioned, for example, between the condenser (560) and the barrier (60).

[0189] The above flow restriction member (590) may be positioned between the first part (562) of the condenser (560) and the barrier (60). The flow restriction member (590) may include a portion that contacts the barrier (60).

[0190] At least a portion of the first wall (602) may overlap the tube (560a) in the Y-axis direction. The first wall (602) may be spaced apart from the tube (560a), and the flow restriction (590) may be positioned between the first wall (602) and the tube (560a).

[0191] At least a portion of the first wall (602) may overlap the first portion (562) of the condenser (560) in the Y-axis direction. At least a portion of the first wall (602) may overlap the second header (560c) in the Y-axis direction.

[0192] Alternatively, at least a portion of the third surface (606a) may overlap the tube (560a) in the Y-axis direction. The third surface (606a) may be spaced apart from the tube (560a), and the flow restriction (590) may be positioned between the third surface (606a) and the tube (560a).

[0193] By the above flow restriction member (590), the air sucked into the air intake port (401) can be restricted from flowing between the first part (562) and the barrier (60). That is, the air sucked into the air intake port (401) can be restricted from flowing toward the compressor (510) without heat exchange with the condenser (560).

[0194] The upper end of the flow restriction member (590) may be positioned higher than the upper end of the barrier (60). The flow restriction member (590) may be in contact with the front plate (480). For example, the flow restriction member (590) may be in contact with at least one of the first part (482) and the second part (484).

[0195] The above flow restriction member (590) can overlap with the sealing member (550) in the X-axis direction. The above flow restriction member (590) can overlap with the fan housing (540) in the X-axis direction.

[0196] Fig. 13 is a cross-sectional view taken along line 13-13 of Fig. 10, and Fig. 14 is a cross-sectional view taken along line 14-14 of Fig. 10.

[0197] Referring to FIGS. 9, 10, 13 and 14, the support member (420) can be accommodated in the recessed portion (410) of the bottom plate (400).

[0198] The above support member (420) may include a base (421) that is mounted on the recessed portion (410). The above support member (420) may further include a peripheral wall (423) extending from the periphery of the base (421).

[0199] The peripheral wall (423) may include a first portion (423a) positioned between the fan housing (540) and the compressor (510). The first portion (423a) may be positioned closer to the compressor (510) than the second wall (604).

[0200] The peripheral wall (423) may further include a guide wall (425) that guides air flowing through the third wall (606) past the fan housing (540) toward the compressor (510). The guide wall (425) may extend upward from the peripheral wall (423). At least a portion of the guide wall (425) may be positioned closer to the compressor (510) than, for example, the second wall (604).

[0201] The above guide wall (425) can also support other parts or support a connecting part that supports other parts.

[0202] A housing support (422) may extend upward from the base (421). A condenser support (424) may extend upward from the base (421). The condenser support (424) may include a portion identical to or similar to the arrangement of the condenser (560).

[0203] The above support member (420) may further include an air guide (426). The air guide (426) may guide air sucked into the air intake (401) toward the condenser (560).

[0204] The air guide (426) may be formed integrally with the support member (420) or may be coupled to the support member (420). The air guide (426) may be inclined downward from the upper end of the peripheral wall (423) toward the air intake (401). The air guide (426) may be mounted on the bottom plate (400). For example, the air guide (426) may be in contact with the first member (411a).

[0205] The sealing member (550) may include a portion provided between the fan housing (540) and the first part (482). The sealing member (550) may include a portion positioned between the fan housing (540) and the second part (484). The sealing member (550) may include a portion (552) positioned between the fan housing (540) and the barrier (60).

[0206] The sealing member (550) may be in contact with the barrier (60). The sealing member (550) may be in contact with the third wall (606), for example. The sealing member (550) may be in contact with the third surface (606a).

[0207] Accordingly, by the sealing member (550), the air sucked into the air intake port (401) can be restricted from flowing between the fan housing (540) and the barrier (60).

[0208] FIG. 15 is a drawing showing air flowing into a refrigerator according to the first embodiment, and FIG. 16 is a drawing showing air flow in a machine room according to the first embodiment.

[0209] Referring to FIGS. 1 to 16, when the refrigerator (1) is placed on the floor (F), the bottom plate (400) can be spaced apart from the floor (F). Accordingly, the air intake port (401) and the air outlet port (403) can be spaced apart from the floor (F).

[0210] When the above refrigerator (1) is installed inside the above cabinet (P), the space between the refrigerator (1) and the inside of the cabinet (P) is narrow.

[0211] Since an opening (P1) is formed in the front of the above-mentioned furniture (P), when the air intake port (401) and the air outlet port (403) are formed in the bottom plate (400) as in the present embodiment, the distance between the air intake port (401) and the opening (P1) of the above-mentioned furniture (P) and the distance between the air outlet port (403) and the opening (P1) of the above-mentioned furniture (P) can be reduced.

[0212] Accordingly, the air outside the furniture (P) can smoothly flow into the air intake port (401). In addition, the air discharged from the air discharge port (403) can smoothly flow outside the furniture (P).

[0213] The air flow in the above machine room (30) is described.

[0214] The air inside the above-mentioned furniture (P) can be introduced into the machine room (30) through the air intake (401).

[0215] Some of the air sucked into the air intake (401) may be guided toward the condenser (560) by the first side plate (440).

[0216] Some of the air sucked into the air intake (401) may be guided toward the condenser (560) by the first surface (602a) of the barrier (60). For example, the air may be guided by the first wall (602) of the barrier (60).

[0217] Some of the air sucked into the air intake (401) may be guided toward the condenser (560) by the front plate (480). For example, the air may be guided by the second part (484).

[0218] Some of the air sucked into the air intake port (401) may be guided by the air guide (426). For example, the air around the second end (401b) of the air intake port (401) may be guided by the air guide (426).

[0219] The air introduced into the machine room (30) may increase in temperature as it exchanges heat with the condenser (560). A portion of the third surface (606a) may guide the air passing through the condenser (560) toward the blower fan (530).

[0220] The high temperature air that has exchanged heat with the condenser (560) may flow toward the compressor (510) by the blower fan (530). For example, the high temperature air may flow toward the compressor (510) by passing through the fan housing (540).

[0221] Another part of the third surface (606a) can guide air passing through the fan housing (540) toward the compressor (510).

[0222] The high temperature air flowing toward the compressor (510) can be discharged to the outside of the machine room (30) through the air discharge port (403).

[0223] According to this embodiment, the air sucked into the machine room (30) can be restricted from flowing directly toward the air discharge port (403) by bypassing the condenser (60) by the barrier (60).

[0224] Additionally, the flow of high temperature air toward the air intake port (401) before it is discharged through the air outlet port (403) can be restricted by the barrier (60).

[0225] The flow of the sucked air toward the air outlet (403) by bypassing the condenser (560) can be restricted by the flow restriction (590) between the barrier (60) and the condenser (560). Therefore, the heat exchange performance of the condenser (560) can be prevented from deteriorating.

[0226] The flow of air between the fan housing (540) and the barrier (60) can be restricted by a sealing member (550) between the barrier (60) and the fan housing (540).

[0227] Some of the high-temperature air may be guided toward the air outlet (403) by the second surface (604a) of the barrier (60). For example, the high-temperature air may be guided by the second wall (604) of the barrier (60).

[0228] The second wall (604) may be positioned closer to the fan housing (540) than to the compressor (510). This may reduce the reduction in the flow rate of air flowing into the air outlet (403).

[0229] Accordingly, since the high-temperature air passes through the air outlet (403) while being guided by the barrier (60), not only can it smoothly pass through the air outlet (403), but the air passing through the air outlet (403) can also smoothly flow toward the opening (P1) of the furniture (P).

[0230] Accordingly, the high temperature air discharged from the air discharge port (403) can be reduced from being re-introduced into the machine room (30) through the air intake port (401).

[0231] As a result, air intake and air discharge can be smoothly performed within the machine room (30), and high-temperature air can be minimized from being sucked into the machine room (30). Accordingly, there is an advantage in that the condensation performance of the condenser (560) and the compression performance of the compressor (510) can be maintained.

[0232] Fig. 17 is a bottom view of a refrigerator according to the second embodiment.

[0233] This embodiment is otherwise identical to the first embodiment, except that it includes an additional partition member. Therefore, only the characteristic parts of this embodiment will be described below, and the same drawing reference numerals will be used for the same components as the first embodiment.

[0234] Referring to Fig. 17, the refrigerator of the present embodiment may further include a partition member (70). The partition member (70) may be located at the lower side of the refrigerator.

[0235] The above partition member (70) may be positioned on the lower side of the plate assembly (40). For example, the above partition member (70) may be installed or coupled to the bottom plate (400).

[0236] The above partition member (70) can limit mixing of air sucked into the air intake port (401) and air discharged from the air discharge port (403).

[0237] For example, the partition member (70) may include a first partition portion (710). The first partition portion (710) may extend in the Y-axis direction.

[0238] The above first compartment (710) can be located in an area corresponding to the area between the air intake port (401) and the air outlet port (403) in the bottom plate (400).

[0239] The first end (711) of the first compartment (710) may be positioned adjacent to the freezer door (25). The second end (712) of the first compartment (710) may be positioned opposite the first end (711) and may be adjacent to or in contact with the recessed portion (410) of the bottom plate (400).

[0240] The first end (711) of the first compartment (710) may be positioned closer to the freezer door (25) than at least one of the air intake port (401) and the air outlet port (403).

[0241] The first end (711) of the first compartment (710) may be positioned closer to the freezer door (25) than the third part (486) of the front plate (480).

[0242] The second end (712) may be positioned closer to the air outlet (403) than the air intake (401). The first end (711) may be positioned closer to the air outlet (403) than the air intake (401).

[0243] The above first section (710) may be inclined in a direction away from the air intake (401) as it moves from the second end (712) to the first end (711).

[0244] Therefore, the distance (W3) from the first end (711) to the first side end (11a) of the cabinet (10) may be greater than the distance (W4) from the first end (711) to the second side end (11b) of the cabinet (10).

[0245] In the present embodiment, the mixing of air sucked into the air intake port (401) and air discharged from the air discharge port (403) can be minimized by the first compartment (710).

[0246] In addition, there is an advantage in that the air discharged from the air discharge port (403) can be guided toward the opening (P1) of the furniture (P) by the first compartment (710).

[0247] The above-described partition member (70) may include a second partition portion (720). The second partition portion (720) may extend from the second end (712) of the first partition portion (710). The second partition portion (720) may extend, for example, in the X-axis direction.

[0248] The above second compartment (720) can extend from the second end (712) in a direction closer to the air outlet (403).

[0249] The second compartment (720) may be positioned adjacent to the second end (403b) of the air outlet (403). The second compartment (720) may be in contact with or adjacent to the recessed portion (410).

[0250] The lower end of the second compartment (720) may be positioned lower than the bottom of the recessed portion (410). Therefore, the second compartment (720) may restrict the air discharged from the air discharge port (403) from flowing toward the rear of the refrigerator.

[0291] The modified examples of the barrier described below have the same basic form as the barrier of the first embodiment, but differ in size, length, arrangement, etc. Therefore, only the characteristic parts of each modified example will be described below, and the same drawing reference numerals will be used for the same configuration.

[0292] First, referring to (a) of FIG. 22, the barrier (60) of the first modified example may include a first wall (602). The barrier (60) may include a first surface (602a), a second surface (604a), and a third surface (606a).

[0293] At least a portion of the first wall (602) or the third surface (606a) may overlap the first portion (562) of the condenser (560) in the Y-axis direction. The first wall (602) may not overlap the first header (560b) in the Y-axis direction.

[0294] At least a portion of the first wall (602) or the third surface (606a) may overlap with the second header (560c) in the Y-axis direction. It is also possible for at least a portion of the first wall (602) or the third surface (606a) to overlap with the second portion (564) in the Y-axis direction.

[0295] A flow restriction (590) may be positioned between the first wall (602) and the tube (560a) of the first portion (562) or between the third surface (606a) and the tube (560a) of the first portion (562).

[0296] Even with this modified example, the air sucked in through the air intake port (401) can be restricted from flowing directly toward the blower fan (530) without passing through the condenser (560).

[0297] Next, referring to (b) of FIG. 22, the barrier (60) of the second modified example may include a first wall (602). The barrier (60) may include a first surface (602a), a second surface (604a), and a third surface (606a).

[0298] At least a portion of the first wall (602) may not overlap with the first portion (562) of the condenser (560) in the Y-axis direction. The first wall (602) or the third surface (606a) may overlap with the first header (560b) in the Y-axis direction.

[0299] A flow restriction (590) may be positioned between the first wall (602) and the first header (560b) or between the third surface (606a) and the first header (560b).

[0300] Even with this modified example, the air sucked in through the air intake port (401) can be restricted from flowing directly toward the blower fan (530) without passing through the condenser (560).

[0301] Next, referring to (c) of FIG. 22, the barrier (60) of the third modified example may include a first wall (602). The barrier (60) may include a first surface (602a), a second surface (604a), and a third surface (606a).

[0302] The first wall (602) or the third surface (606a) may not overlap with the condenser (560) in the Y-axis direction. That is, the first surface (602a) may be positioned closer to the blower fan (530) than to the condenser (560).

[0303] A flow restriction (590) may be positioned between the first wall (602) and the first header (560b) or between the third surface (606a) and the first header (560b).

[0304] At this time, the X-axis direction length of the flow restriction part (590) may be greater than the X-axis direction length of the flow restriction part (590) in the second modified example.

[0305] The above flow restriction portion (590) may include a portion positioned further away from the blower fan (530) than the first surface (602a).

[0306] Even with this modified example, the air sucked in through the air intake port (401) can be restricted from flowing directly toward the blower fan (530) without passing through the condenser (560).

[0307] In addition, in the case of this modified example, since the first surface (602a) is positioned close to the blower fan (530), the area of ​​the air intake port (401) of this modified example can be increased compared to the area of ​​the air intake port (401) of the first or second modified example.

[0308] Fig. 23(A) is a drawing showing a fourth modified example of the barrier in the first embodiment, and Fig. 23(B) is a drawing showing a fifth modified example of the barrier in the first embodiment.

[0311] The second surface (604a) may be positioned further from the compressor (510) than at least a portion of the fan housing (540).

[0312] The sealing member (550) may be positioned between the second wall (604) and the fan housing (540) or between the third surface (606a) and the fan housing (540).

[0313] Even with this modified example, the air flowing through the condenser (560) can be restricted from flowing between the fan housing (540) and the barrier (60).

[0314] In the case of this modified example, since the second surface (604a) is positioned further from the compressor (510) than at least a portion of the fan housing (540), there is an advantage in that the area of ​​the air outlet (403) of this modified example can be increased compared to the air outlet (403) of the first embodiment.

[0315] Additionally, in the case of this modified example, the length of the guide wall (425) illustrated in FIG. 9 can be adjusted so that the guide wall (425) guides the air passing through the fan housing (540) toward the compressor (510).

[0316] Next, referring to (B) of FIG. 23, the barrier (60) of the fifth modified example may include a second wall (604).

[0317] The above barrier (60) may include the first side (602a), the second side (604a), and the third side (606a).

[0318] The second wall (604) may not overlap with the fan housing (540) in the Y-axis direction. The second wall (604) or the second surface (604a) may be positioned closer to the first portion (423a) of the peripheral wall (423) than to the fan housing (540).

[0319] The sealing member (550) may be provided between the third surface (606a) and the fan housing (540).

[0320] In this modified example, the length of the third side (606a) of the barrier (60) can be increased so that the third side (606a) can sufficiently guide the air passing through the fan housing (540) toward the compressor (510).

[0321] In the above support member (450), the guide wall (425) may be omitted or present. When the support member (450) includes the guide wall (425), the second wall (604) or the second surface (604a) may be positioned closer to the compressor (510) than the guide wall (425).

[0322] Next, referring to FIG. 24, the barrier (60) of the sixth modified example may include a second wall (604).

[0323] The barrier (60) may include a first surface (602a), a second surface (604a), and a third surface (606a). The second wall (604) or the second surface (604a) may be positioned closer to the compressor (510) than the first portion (423a) of the peripheral wall (423).

[0324] The sealing member (550) may be provided between the third surface (606a) and the fan housing (540).

[0325] In this modified example, the third side (606a) of the barrier (60) can sufficiently guide the air passing through the fan housing (540) toward the compressor (510).

[0326] Variations derived by combining the first to sixth variations in this specification may also be included in the spirit of the present invention.

[0327] Fig. 25 is a drawing showing a first modified example of a support member in the first embodiment.

[0328] Referring to FIG. 25, the support member (420) may include a peripheral wall (423). The peripheral wall (423) may further include a guide wall (425a) that guides air flowing through the third surface (606a) of the barrier (60) toward the compressor (510).

[0329] The above guide wall (425a) may extend upward from the peripheral wall (423). The guide wall (425a) may extend from a portion adjacent to the second wall (604) toward the first portion (423a). The guide wall (425a) may extend to the first portion (423a) of the peripheral wall (423) or to an adjacent portion.

[0330] The above guide wall (425a) can overlap with the third surface (606a) in the Y-axis direction.

[0331] In the case of this modified example, the air flowing through the third side (606a) of the barrier (60) can be sufficiently guided by the guide wall (425a) toward the compressor (510).
