[0043] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0044] At present, with the improvement of people's material living standards, refrigerators, as devices that can refrigerate or freeze food, have become indispensable electrical appliances in life. At present, double-door refrigerators are more and more widely used.

[0045] In the related art, a door seal is usually provided between the door and the refrigerator body to seal the storage compartment.

[0046] The problem with the related technology is that, on the one hand, the door seal may not be sealed tightly, and on the other hand, due to the sinking of low-temperature air, the temperature of the refrigerator body near the door seal at the bottom is relatively low. Since this position is close to the ground and the air circulation is poor, condensation is very likely to occur at this position. The condensation produced will absorb dust and debris in the air, and long-term condensation will cause corrosion and rust of metal parts and mold of plastic parts, thereby reducing the service life of the refrigerator.

[0047] Therefore, an embodiment of the present disclosure provides a refrigerator to prevent condensation from forming on a box body at the bottom of the refrigerator, thereby increasing the service life of the refrigerator.

[0048] Combination Figures 1 to 5 As shown, the embodiment of the present disclosure provides a refrigerator, including a box body 100, a door body 200 and a base cover shell 300, wherein a refrigeration chamber is defined inside the box body 100, a compressor cavity is provided at the bottom of the box body 100, and the box body 100 includes a bottom beam 116; the door body 200 is pivotally connected to the box body 100 and abuts against the bottom beam 116; the base cover shell 300 is covered on the bottom beam 116 and communicated with the compressor cavity, the base cover shell 300 is located below the door body 200, the base cover shell 300 includes a top air outlet plate 310 facing the door body 200, an air outlet 311 is provided on the top air outlet plate 310, the air outlet 311 is provided with a first grille 312, and an air outlet channel 313 is formed between adjacent first grilles 312.

[0049] Optionally, the box body 100 includes an outer shell 110 and an inner liner. The inner bottom wall of the inner liner is bent and formed, and the inner bottom wall includes an inner high-order plate, an inner connecting plate, and an inner low-order plate. The outer shell 110 includes an outer bottom wall 111, and the outer bottom wall 111 is correspondingly bent and formed corresponding to the inner bottom wall. The outer bottom wall 111 includes an outer high-order plate, an outer connecting plate, and an outer low-order plate.

[0050] The box body also includes a bottom plate cover 120, and a compressor cavity is formed between the outer high-order plate and the bottom plate cover 120. The compressor cavity is provided with a compressor 410, a fan 420 and a condenser at the same time. Among them, the fan 420 is arranged between the compressor 410 and the condenser to separate the compressor cavity into two independent parts. During the operation of the fan 420, the driving air flows through the condenser, the fan 420 and the compressor 410 in sequence. Since the condenser and the compressor 410 release heat during the operation, the condenser and the compressor 410 can be cooled down.

[0051] Optionally, the housing 110 further includes a left side wall 112 and a right side wall 113, the bottom plate cover 120 is connected between the left side wall 112 and the right side wall 113, and the bottom plate cover 120 includes a bottom plate 121 and a front side plate 122 that bends and extends upward along the front side edge of the bottom plate 121, wherein a certain gap exists between the outer low-level plate of the outer bottom wall 111 and the placement surface of the box body 100, and a certain gap exists between the front side plate 122 and the outer connecting plate. An air inlet 510 and an air outlet 520 are provided on the side end of the bottom plate 121 close to the front side plate 122 and on the front side plate 122, wherein the air inlet 510 is arranged corresponding to the condenser, and the air outlet 520 is arranged corresponding to the compressor 410. In this way, during the operation of the refrigerator, the driving air flows in the gap between the outer bottom wall 111 and the placement surface of the box body 100, and enters the compressor cavity through the air inlet 510, and after cooling the condenser and the compressor 410, it flows out of the compressor cavity through the air outlet 520.

[0052] Optionally, a partition plate 115 is provided on the side of the outer bottom wall 111 facing the placement surface, and the partition plate 115 is arranged along the longitudinal direction of the box body 100, that is, along the depth direction of the box body 100, so as to be located between the bottom plate cover 120 and the base cover 300. The partition plate 115 is arranged corresponding to the fan 420, so that the space on the side of the air inlet 510 can be separated from the space on the side of the air outlet 520, so as to prevent the air outlet 520 from being directly sucked back to the air inlet 510, thereby ensuring the cooling effect on the condenser and the compressor 410.

[0053] Optionally, the door body 200 is pivotally connected to the box body 100 to rotate to open or close the storage compartment in the box body 100. Among them, the box body 100 also includes a bottom beam 116 arranged at the bottom end, and the door body 200 can abut against the bottom beam 116 when the storage compartment is closed. Optionally, a sealing strip is provided along the periphery of the inner side of the door body 200 to facilitate sealing the storage compartment. However, even if a sealing strip is provided, the cold in the storage compartment will leak. After the cold in the storage compartment escapes, the temperature of the bottom beam 116 will be kept at a low temperature. The bottom beam 116 in a low temperature state contacts with the indoor air, and condensation is generated on the bottom beam 116 after reaching the dew point temperature. Condensation not only absorbs dust and debris in the air, but also long-term generation of condensation will cause the metal parts on the box body 100 to corrode and rust, and the plastic parts to mold, thereby reducing the service life of the refrigerator.

[0054] Optionally, the base cover 300 is located below the door body 200 and is covered by the bottom beam 116, and includes a top air outlet plate 310 arranged toward the door body 200, wherein a gap is provided between the top air outlet plate 310 and the bottom end of the door body 200 to facilitate opening or closing of the door body 200. The base cover 300 is connected to the compressor cavity to guide the hot air in the compressor cavity into the base cover 300.

[0055] By setting the air outlet 311 on the top air outlet plate 310, the hot air in the compressor cavity can be guided out of the gap between the door body 200 and the base cover 300, so that the hot air can be used to heat the bottom beam 116, thereby avoiding the generation of condensation on the bottom beam 116, or the hot air can be used to evaporate the generated condensation to remove the condensation. Furthermore, the air outlet 311 is provided with a first grille 312, and an air outlet channel 313 is formed between adjacent first grilles 312. In this way, through the air outlet channel 313, the hot air can flow to the bottom beam 116 in a relatively dispersed manner to avoid the situation where the local heat is high and the temperature in other locations is low.

[0056] Optionally, the air outlet 311 is correspondingly arranged on one side of the air outlet 520, and the air outlet 311 is not arranged on one side of the air inlet 510, so as to prevent the air from further flowing to the air inlet 510 through the air outlet 311, and to prevent the air that has not flowed through the compressor cavity from affecting the outflow of the hot air through the air outlet 311, thereby ensuring the flow of the hot air to the bottom beam 116. After the hot air flows out through the air outlet channel 313, it collides with the bottom beam 116 and the bottom end of the door body 200, and can be dispersed in the direction where the air outlet 311 is not arranged. Through the further flow of the hot air and the radiation of heat, the condensation can be prevented from being generated in the part where the air outlet 311 is not arranged, or the condensation can be cleared.

[0057] The refrigerator provided by the embodiment of the present disclosure has a base cover shell connected to the compressor cavity disposed at the bottom of the box body, so that the hot air in the compressor cavity can be guided into the base cover shell. Furthermore, the hot air can be guided to the bottom beam at the bottom of the box body through the air outlet disposed on the top air outlet plate of the base cover shell. The blown hot air can be dispersed by the grille disposed at the air outlet, and the air flow rate can be effectively reduced, thereby achieving a uniform heating effect on the bottom beam, thereby avoiding the generation of condensation.

[0058] Optionally, the first grille 312 extends in the transverse direction of the box 100 and is arranged at intervals in the longitudinal direction of the box 100. It should be noted that the transverse direction of the box 100 is the length direction of the first grille 312, and the longitudinal direction of the box 100 (the depth direction of the storage compartment) is the width direction of the top air outlet plate 310. In this way, the air outlet 311 can be divided into a plurality of air outlet channels 313 in the width direction of the top air outlet plate 310, so that the hot air flowing out of the air outlet channels 313 at the air outlet 311 can be made more uniform, achieving a smooth hot air outlet effect.

[0059] Optionally, the first grille 312 is arranged in multiple sections at intervals along the lateral direction of the box body 100. The lateral direction of the box body 100 mentioned here is the length direction of the top air outlet plate 310. On the side corresponding to the air outlet 520, the first grille 312 is arranged with multiple sections of sub-grates at intervals along the length direction of the top air outlet plate 310. In this way, the hot air passing through the air outlet 311 can be further dispersed to improve the heating effect on the bottom beam 116.

[0060] Optionally, adjacent sub-grates are staggered in the length direction of the top air outlet plate 310 to improve the dispersion effect of hot air.

[0061] Optionally, the first grille 312 includes a first side end and a second side end, wherein the first side end is close to the bottom beam 116 ; the second side end is away from the bottom beam 116 ; the first grille 312 is inclined upward from the second side end to the first side end.

[0062] In this way, the flow direction of the hot air can be changed, and while ensuring the dispersion effect of the hot air, the hot air can flow toward the bottom beam 116 to avoid the hot air flow blowing directly to the bottom end of the door body 200, thereby ensuring the heating effect of the bottom beam 116.

[0063] Optionally, the first grille 312 is fixedly connected to an edge of the air outlet 311 .

[0064] That is, the first grille 312 is fixedly connected to the top air outlet plate 310. Optionally, the first grille 312 is connected to the edge of the air outlet 311 by welding. In this way, the connection strength can be ensured. Optionally, the first grille 312 is integrally formed with the edge of the air outlet 311. In this way, the installation steps of the first grille 312 can be reduced, and the manufacturing cost can be reduced.

[0065] Optionally, the intervals between adjacent first grids 312 are equal.

[0066] The first air outlet 311 can be divided into a plurality of air outlet channels 313 by the first grille 312 provided at the air outlet 311. Through the formation of the air outlet channels 313, hot air can flow to the bottom beam 116 in a dispersed manner to avoid local high heat. Optionally, the spacing between adjacent first grilles 312 is equal. In this way, the uniformity of hot air flowing out of the air outlet 311 along the top air outlet plate 310 can be further ensured.

[0067] Optionally, the surface of the bottom beam 116 is coated with a hydrophobic coating.

[0068] Optionally, the hydrophobic coating is a nano hydrophobic coating, or the hydrophobic coating is a graphene hydrophobic coating. By setting the hydrophobic coating, the formation of condensation on the bottom beam 116 or the adsorption of condensation can be reduced, thereby extending the service life of the refrigerator.

[0069] Optionally, the surface of the top air outlet plate 310 is coated with a hydrophobic coating.

[0070] Optionally, the hydrophobic coating is a nano hydrophobic coating, or the hydrophobic coating is a graphene hydrophobic coating. By setting the hydrophobic coating, the formation of condensation or the adsorption of condensation on the top air outlet plate 310 can be reduced, thereby extending the service life of the base cover 300.

[0071] Optionally, the base housing 300 further includes a front air outlet plate 320 , which is bent and connected to the top air outlet plate 310 . A second grille 321 is disposed at one end of the front air outlet plate 320 away from the top air outlet plate 310 , and a heat dissipation channel is disposed between adjacent second grilles 321 .

[0072] The second grille 321 is provided to improve the fluidity of the air. The air can flow into the space corresponding to the air inlet 510 below the outer bottom wall 111 through the second grille 321, and then enter the compressor cavity through the air inlet 510, and the air outlet 520 after absorbing the heat of the condenser and the compressor 410 flows into the space corresponding to the air outlet 520 below the outer bottom wall 111, and further, part of the hot air flows to the bottom beam 116 through the air outlet channel 313 between the first grilles 312, and another part of the hot air flows back to the indoor air through the heat dissipation channel between the second grilles 321.
