Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to a refrigerator. Background Technology

[0002] For built-in refrigerators, the rear panel is typically installed close to the shelf, with virtually no heat dissipation channels. Therefore, the compressor compartment's heat dissipation primarily relies on the fixed gap between the bottom steel plate and the ground. This means that the bottom steel plate of the compressor compartment has an air inlet and outlet connected to the compartment. However, in related technologies, the air inlet and outlet on the bottom steel plate of the compressor compartment are positioned too close together. Due to limited heat dissipation space, the warmer exhaust air can easily re-enter the inlet, resulting in a higher inlet temperature. Consequently, the high-temperature heat from the refrigerant passing through the condenser cannot be completely dissipated, leading to decreased cooling efficiency and increased energy consumption. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of this utility model propose a refrigerator with high heat dissipation efficiency in the compressor compartment, which gives the refrigerator the advantages of high cooling efficiency and low energy consumption.

[0005] The refrigerator of this utility model embodiment includes a cabinet and a rear cover. The cabinet has a compressor compartment, and the rear cover is used to cover the rear opening of the compressor compartment. The compressor compartment has a first air inlet and at least one air outlet. The first air inlet is located on the rear cover, and all the air outlets are located on the bottom plate of the cabinet.

[0006] According to the refrigerator of this embodiment, by placing the first air inlet of the compressor compartment on the rear cover plate and placing all the air outlets of the compressor compartment on the bottom plate of the cabinet, the probability of cross-flow between the air outlets and the first air inlet is low, and the hot air discharged from the air outlets is less likely to enter the compressor compartment through the first air inlet, resulting in high heat dissipation efficiency of the compressor compartment. Furthermore, compared to related technologies where the air outlets are located on the rear cover plate, in this embodiment, when the refrigerator is installed in a recessed manner, the space below the bottom plate can form a larger heat dissipation channel than the space behind the rear cover plate, thereby further improving the heat dissipation efficiency of the compressor compartment, resulting in higher cooling efficiency and lower energy consumption for the refrigerator.

[0007] In some embodiments, the refrigerator further includes a compressor and a condenser fan, wherein the first air inlet is located on the side of the rear cover near the condenser fan, and no air inlet is provided on the side of the rear cover near the compressor.

[0009] In some embodiments, the base plate is provided with a lower air inlet communicating with the compressor chamber, and the lower air inlet and the first air inlet are located on the same side opposite to each other in the left-right direction of the air outlet.

[0011] In some embodiments, the lower air inlet includes a second air inlet disposed on the first plate portion, and the second air inlet and the air outlet are arranged at intervals along the left-right direction of the housing.

[0015] In some embodiments, the lower air inlet further includes a third air inlet formed between the first plate portion and the second plate portion, and the third air inlet and the air outlet are arranged at intervals along the left-right direction of the housing.

[0016] In some embodiments, the refrigerator further includes an air guide strip disposed below the base plate, the air guide strip separating the air outlet and the lower air inlet.

[0027] The embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] The following is combined Figures 1-5 A refrigerator according to an embodiment of the present utility model is described.

[0029] The refrigerator of this utility model embodiment includes a cabinet 1 and a rear cover plate 2. The cabinet 1 has a compressor compartment, and the rear cover plate 2 is used to cover the rear opening of the compressor compartment. The compressor compartment has a first air inlet 22 and at least one air outlet 12. The first air inlet 22 is located on the rear cover plate 2, and all air outlets 12 are located on the bottom plate 11 of the cabinet 1.

[0030] According to the refrigerator of this embodiment, by setting the first air inlet 22 of the compressor compartment on the rear cover plate 2 and setting all the air outlets 12 of the compressor compartment on the bottom plate 11 of the cabinet 1, the probability of cross-flow between the air outlets 12 and the first air inlet 22 is low, and the hot air discharged from the air outlets 12 is less likely to enter the compressor compartment through the first air inlet 22, resulting in high heat dissipation efficiency of the compressor compartment. Furthermore, compared to the related art where the air outlets 12 are located on the rear cover plate 2, in this embodiment, when the refrigerator is embedded, the space below the bottom plate 11 can form a larger heat dissipation channel than the space behind the rear cover plate 2, thereby further improving the heat dissipation efficiency of the compressor compartment, resulting in higher cooling efficiency and lower energy consumption for the refrigerator.

[0031] It should be noted that the compressor compartment is located at the rear bottom of the cabinet 1, and the rear cover plate 2 is connected to the bottom plate 11 of the cabinet 1. In addition, when the refrigerator is installed in a built-in manner, the distance between the rear cover plate 2 and the rear partition plate 5 is between 5mm and 10mm, and the distance between the bottom plate 11 and the ground is between 20mm and 30mm.

[0032] In some embodiments, the refrigerator further includes a compressor and a condenser fan, with a first air inlet 22 located on the side of the rear cover 2 near the condenser fan, and no air inlet on the side of the rear cover 2 near the compressor.

[0033] That is, all the air inlets on the rear cover plate 2 are located near the condenser fan and far away from the compressor, which makes it easier for the gas entering the compressor chamber to be drawn into the condenser fan more smoothly, and the heat dissipation air duct formed in the compressor chamber is more stable and smooth.

[0034] For example, the compressor and the condenser fan are arranged in the left-right direction along the housing 1, such that the condenser fan is located on the left side of the compressor, the first air inlet 22 is adjacent to the left side of the rear cover plate 2, and the air outlet 12 is adjacent to the right side of the bottom plate 11.

[0035] Alternatively, the condenser fan can be an axial flow fan, which produces lower noise when dissipating heat from the condenser, resulting in a better user experience.

[0036] In some embodiments, such as Figure 1 and Figure 3 As shown, the bottom plate 11 is provided with a lower air inlet 13 that communicates with the compressor chamber. The lower air inlet 13 and the first air inlet 22 are located on the same side of the air outlet 12 in the left-right direction of the housing 1.

[0037] The lower air inlet 13 increases the air intake area of ​​the compressor chamber, resulting in smoother airflow within the cooling duct formed in the compressor chamber and better heat dissipation for the condenser. The lower air inlet 13 and the first air inlet 22 are located on the same side of the air outlet 12 along the left-right direction of the housing 1, ensuring that both are close to the condenser fan. This facilitates the direct cooling of the radiator by the cold air entering the compressor chamber through the lower air inlet 13.

[0038] For example, such as Figure 1 and Figure 3 As shown, the compressor, the first air inlet 22 and the lower air inlet 13 are all located at the right end of the housing 1, while the condenser and the air outlet 12 are located at the left end of the housing 1.

[0039] In some embodiments, the bottom plate 11 of the housing 1 includes a first plate portion 111 and a second plate portion 112. The first plate portion 111 is used to cover the bottom opening of the press chamber, and the second plate portion 112 is located on the side of the first plate portion 111 away from the rear cover plate 2. An air outlet 12 is formed between the first plate portion 111 and the second plate portion 112, or the air outlet 12 is located at the end of the first plate portion 111 near the second plate portion 112.

[0040] That is, while ensuring that the air outlet 12 is connected to the compressor compartment and is close to the condenser, the air outlet 12 is also further away from the first air inlet 22 located on the rear cover plate 2 in the front-back direction. The distance between the two is longer, the probability of crossflow is lower, the heat dissipation effect of the compressor compartment is higher, and the cooling efficiency of the refrigerator is higher.

[0041] For example, such as Figure 3 As shown, the first plate portion 111 is located behind the second plate portion 112. At the intersection of the first plate portion 111 and the second plate portion 112, an air outlet 12 extending in the left-right direction of the housing 1 is formed due to the height difference. The length of the air outlet 12 in the left-right direction is approximately greater than or equal to the length of the bottom plate 11 in the left-right direction.

[0042] In some embodiments, the lower air inlet 13 includes a second air inlet 131 disposed on the first plate portion 111, and the second air inlet 131 and the air outlet 12 are arranged at intervals along the left and right directions of the housing 1.

[0043] At this point, the second air inlet 131 is closer to the condenser inside the compressor compartment. The air intake through the second air inlet 131 can more directly dissipate heat from the condenser, resulting in better heat dissipation. Furthermore, the second air inlet 131 and the air outlet 12 are spaced apart in the left-right direction, reducing the likelihood of cross-flow between them.

[0044] For example, such as Figure 1 and Figure 3As shown, the second air inlet 131 is located at the left end of the first plate portion 111, and the minimum distance between the second air inlet 131 and the air outlet 12 is greater than or equal to 70mm.

[0045] In some embodiments, the first air inlet 22 includes a plurality of first air inlets 221 arranged in an array, and the plurality of first air inlets 221 are disposed at the lower end of the rear cover plate 2. The second air inlet 131 includes a plurality of second air inlets 1311 arranged in an array, and the plurality of second air inlets 1311 are disposed at one end of the first plate portion 111 near the second plate portion 112.

[0046] By setting multiple first air inlets 221 at the lower end of the rear cover plate 2 and multiple second air inlets 1311 at the front end of the first plate 111, the airflow entering the compressor chamber through the second air inlets 1311 is less likely to be blown out through the first air inlets 221, resulting in higher air intake efficiency and better heat dissipation in the compressor chamber.

[0047] In addition, the grille structure of the first air inlet 22 and the second air inlet 131 ensures that the cross-sectional area of ​​the formed first air inlet 221 and the second air inlet 1311 is smaller, effectively preventing external insects, mice and other animals from entering the compressor chamber and affecting the refrigerator's cooling function, and also effectively improving the structural strength of the rear cover 2 and the first plate 111.

[0048] For example, such as Figures 2-4 As shown, the first air inlet 221 has two rows arranged in the vertical direction, and each row of the first air inlet 22 includes multiple first air inlets 22 arranged at intervals in the horizontal direction. The second air inlet 131 has two rows arranged in the vertical direction, and each row of the second air inlet 131 includes multiple second air inlets 131 arranged at intervals in the horizontal direction. All the second air inlets 131 are located at the front of the first plate portion 111.

[0049] In some embodiments, such as Figure 1 and Figure 2 As shown, the multiple first air inlets 221 are arranged in two rows along the vertical direction of the housing 1, and the outer contours of the two rows of first air inlets 221 are U-shaped. That is, the number of first air inlets 221 in the upper row is less than the number of first air inlets 221 in the lower row, and the distribution of the first air inlets 221 is closer to the lower edge of the rear cover plate 2. As a result, the airflow entering the compressor chamber through the second air inlet 1311 is less likely to be blown out through the first air inlet 221, resulting in higher air intake efficiency and better heat dissipation in the compressor chamber.

[0050] For example, the first air inlet 221 is a strip-shaped hole extending in the vertical direction. There are 8 first air inlets 221 in the upper row and 11 first air inlets 221 in the lower row.

[0051] In some embodiments, the lower air inlet 13 further includes a third air inlet 132 formed between the first plate portion 111 and the second plate portion 112, and the third air inlet 132 and the air outlet 12 are arranged at intervals along the left and right directions of the housing 1.

[0052] The third air inlet 132 is located at the front end of the first plate 111. The third air inlet 132 is further away from the first air inlet 22 in the front-back direction. The airflow entering the compressor chamber through the third air inlet 132 is not easily discharged directly through the first air inlet 22, thereby further improving the air intake efficiency and heat dissipation efficiency of the compressor chamber.

[0053] Specifically, such as Figure 3 As shown, the third air inlet 132 extends in the left and right direction, and the distance between the third air inlet 132 and the air outlet 12 is greater than or equal to 70mm.

[0054] In some embodiments, the refrigerator further includes an air guide strip disposed below the base plate 11, which separates the air outlet 12 and the lower air inlet 13.

[0055] The air guide strip divides the space below the base plate 11 into an air outlet area connected to the air outlet 12 and an air inlet area connected to the lower air inlet 13. This further reduces the distance that the air from the air outlet 12 travels through the lower air inlet 13 to re-enter the compressor chamber, resulting in higher heat dissipation efficiency in the compressor chamber, higher cooling efficiency in the refrigerator, and lower energy consumption.

[0056] Specifically, the air guide strip can be welded to the base plate 11. The distance between the portion of the air guide strip protruding below the base plate 11 in the vertical direction is less than the distance between the base plate 11 and the ground, but greater than half of the distance between the base plate 11 and the ground.

[0057] In some embodiments, the air guide strip includes a first air guide strip 3, which is disposed on the side of the air outlet 12 facing the rear cover plate 2, and extends in the left-right direction.

[0058] The first air guide strip 3 prevents the hot air discharged from the air outlet 12 from flowing to the rear side, thereby preventing the hot air from entering the gap between the rear cover plate 2 and the rear partition plate 5 and then entering the compressor chamber through the first air inlet 22, effectively ensuring the heat dissipation efficiency of the compressor chamber.

[0059] Specifically, such as Figure 1 and Figure 3 As shown, the first air guide strip 3 is connected to the first plate 111. The length of the first air guide strip 3 is greater than or equal to the length of the air outlet 12. The two ends of the air outlet 12 in the left and right directions are located inside the two ends of the first air guide strip 3 in the left and right directions.

[0060] In some embodiments, the air guide strip further includes a second air guide strip 4, which is disposed between the air outlet 12 and the lower air inlet 13. The second air guide strip 4 is connected to the first air guide strip 3 and extends along the front-rear direction of the compressor chamber.

[0061] The second air guide strip 4 prevents the hot air discharged from the air outlet 12 from flowing to the left side to the vicinity of the second air inlet 131 and the third air inlet 132, thereby avoiding crossflow between each of the second air inlet 131 and the third air inlet 132 and the air outlet 12, effectively ensuring the heat dissipation efficiency of the compressor chamber.

[0062] Specifically, such as Figure 1 and Figure 3 As shown, the second air guide strip 4 is connected to the second plate portion 112, and the rear end of the second air guide strip 4 is connected to the left end of the first air guide strip 3.

[0063] In some embodiments, both the first air guide strip 3 and the second air guide strip 4 include a connecting plate and a guide plate connected at an angle. The connecting plate is connected to the base plate 11, and the guide plate is located below the connecting plate. This facilitates the connection between the connecting plate and the base plate 11, and also makes it easier for the guide plate to achieve the effects of guiding and blocking the airflow.

[0064] For example, both the first air guide strip 3 and the second air guide strip 4 are L-shaped plates, that is, the connecting plate is perpendicular to the guide plate and the connecting plate is welded to the base plate 11.

[0065] In some embodiments, such as Figure 5 As shown, the refrigerator is a built-in refrigerator. That is, the left, right and rear sides of the refrigerator body 1 are provided with wooden partitions 5, and the gaps between the body 1 are arranged in the installation cavity formed by the three partitions 5.
