Description

Technical Field

[0001] This application relates to the field of refrigerator heat dissipation technology, and in particular to a refrigerator bottom component and a refrigerator. Background Technology

[0002] With the increasing popularity of integrated home design, built-in refrigerators are gradually becoming an important development direction for modern kitchen appliances due to their ability to seamlessly integrate with cabinets and save kitchen space. Built-in refrigerators typically need to be installed tightly against cabinets, with their back, sides, and top often surrounded by the cabinet structure, leaving only a gap between the front and the cabinet door. Therefore, the bottom heat dissipation structure needs to be adapted accordingly.

[0003] In existing technology, an air inlet and an air outlet are located on the front side of the bottom of a built-in refrigerator, and these are connected to the compressor compartment via air inlet and outlet channels. The condenser and condenser fan are arranged inside the compressor compartment to form a heat dissipation structure. In this design, when the built-in refrigerator is small, the placement of the air inlet and outlet channels further compresses the bottom space. The size of the condenser is limited by the space, resulting in a limited area for heat exchange between the condenser and the air. Consequently, the efficiency of heat exchange between the refrigerant and the air inside the condenser is low, and the heat dissipation effect of the refrigerant flowing inside the condenser is poor. Utility Model Content

[0004] Therefore, it is necessary to provide a refrigerator bottom component and a refrigerator that can solve the above problems.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0006] A refrigerator bottom assembly, the refrigerator bottom assembly comprising:

[0007] The bottom body of the refrigerator is enclosed to form an air inlet channel, a compressor compartment, and an air outlet channel, wherein the air inlet channel is connected to the air outlet channel through the compressor compartment;

[0008] The condenser includes a main condenser and a first auxiliary condenser. The main condenser is located in the area where the compressor compartment is located, and the first auxiliary condenser is located in the area where the air outlet duct is located. Furthermore, the first auxiliary condenser is connected in series with the main condenser.

[0009] It is understandable that this application increases the heat exchange area by setting a first auxiliary condenser in series with the main condenser in the air outlet duct and using the first auxiliary condenser for auxiliary heat exchange. When air enters the compressor chamber through the air inlet duct, it first exchanges heat with the main condenser and continues to exchange heat with the first auxiliary condenser when it is discharged from the air outlet duct. This allows the air entering the bottom of the refrigerator to fully exchange heat with the high-temperature refrigerant, enhancing the heat dissipation effect of the refrigerant flowing in the condenser.

[0010] In one embodiment, the first auxiliary condenser includes a first condenser tube, and the first auxiliary condenser is connected in series with the main condenser through the first condenser tube;

[0011] The first condenser tube includes multiple first condenser straight tube sections, which are arranged sequentially at intervals along the depth direction of the refrigerator, and are connected end to end sequentially along the length direction of the refrigerator.

[0012] In one embodiment, the first auxiliary condenser further includes a plurality of first fins, which are arranged sequentially at intervals along the length of the refrigerator, and each first fin is simultaneously connected to a plurality of first condenser straight pipes.

[0013] It is understandable that by setting multiple first fins, the effective heat dissipation surface area of ​​the first auxiliary condenser can be increased, thereby enhancing the heat dissipation effect of the first auxiliary condenser.

[0014] In one embodiment, the flow area of ​​the air outlet channel is set to A1, and the cross-sectional area of ​​the first auxiliary condenser perpendicular to the air outlet direction of the air outlet channel is set to A2, wherein 12%A1≤A2≤30%A1.

[0015] Understandably, by limiting 12%A1≤A2≤30%A1, the heat dissipation performance of the condenser and the airflow resistance of the air outlet can be balanced. This ensures that after the first auxiliary condenser is installed, the condenser has sufficient heat dissipation area, but the air outlet is not excessively blocked, preventing the problem of insufficient airflow, thereby maintaining the heat dissipation stability of the bottom components of the refrigerator.

[0016] In one embodiment, the condenser further includes a second auxiliary condenser, which is disposed in the area where the air inlet channel is located, and the second auxiliary condenser is connected in series with the main condenser.

[0017] In one embodiment, the second auxiliary condenser includes a second condenser tube, and the second auxiliary condenser is connected in series with the main condenser through the second condenser tube;

[0018] The second condenser tube includes multiple second condenser straight tube sections, which are arranged sequentially at intervals along the depth direction of the refrigerator, and are connected end to end sequentially along the length direction of the refrigerator.

[0019] Understandably, by setting up a second auxiliary condenser, the total heat dissipation area can be further increased, thereby improving the overall heat exchange efficiency of the refrigerator's bottom components.

[0020] In one embodiment, the second auxiliary condenser further includes a plurality of second fins, which are arranged sequentially at intervals along the length of the refrigerator, and each second fin is simultaneously connected to a plurality of second condenser straight pipes.

[0021] It is understandable that by setting multiple second fins, the effective heat dissipation surface area of ​​the second auxiliary condenser can be increased, thereby enhancing the heat dissipation effect of the second auxiliary condenser.

[0022] In one embodiment, the flow area of ​​the air inlet channel is set to B1, and the cross-sectional area of ​​the second auxiliary condenser perpendicular to the air inlet direction of the air inlet channel is set to B2, wherein 12%B1≤B2≤30%B1.

[0023] Understandably, by limiting 12%B1≤B2≤30%B1, the heat dissipation performance of the condenser and the airflow resistance of the air inlet channel can be balanced. This ensures that after installing the second auxiliary condenser, the condenser has sufficient heat dissipation area, but the air inlet channel is not excessively blocked, preventing the problem of insufficient airflow, thereby maintaining the heat dissipation stability of the bottom components of the refrigerator.

[0024] In one embodiment, the refrigerator bottom assembly further includes a compressor disposed in the area where the compressor compartment is located;

[0025] The first auxiliary condenser is connected to and in communication with the compressor;

[0026] The second auxiliary condenser includes a refrigerant connection pipe that passes through the bottom body of the refrigerator in the height direction and extends outward.

[0027] This application also provides the following technical solutions:

[0028] A refrigerator includes a refrigerator bottom assembly as described in any of the above embodiments.

[0029] Compared with the prior art, the refrigerator has a first auxiliary condenser connected in series with the main condenser in the air outlet duct. The auxiliary condenser provides auxiliary heat exchange, which increases the heat exchange area. When air enters the compressor chamber through the air inlet duct, it first exchanges heat with the main condenser and continues to exchange heat with the first auxiliary condenser when it is discharged from the air outlet duct. This allows the air entering the bottom of the refrigerator to fully exchange heat with the high-temperature refrigerant, enhancing the heat dissipation effect of the refrigerant flowing in the condenser.

[0044] Please see Figures 1 to 6This application provides a refrigerator bottom assembly 100, which is disposed at the bottom of the refrigerator for heat dissipation. The refrigerator bottom assembly 100 includes a refrigerator bottom body 10 and a condenser 20. The refrigerator bottom body 10 encloses an air inlet channel 11, a compressor compartment 12, and an air outlet channel 13. The air inlet channel 11 is connected to the air outlet channel 13 through the compressor compartment 12. The condenser 20 includes a main condenser 21 and a first auxiliary condenser 22. The main condenser 21 is disposed in the area where the compressor compartment 12 is located, and the first auxiliary condenser 22 is disposed in the area where the air outlet channel 13 is located. Furthermore, the first auxiliary condenser 22 is connected in series with the main condenser 21. Here, the main condenser 21 and the first auxiliary condenser 22 can be selected from structures such as wire tube condensers, finned condensers, or plate tube condensers.

[0045] As can be seen from the above, this application provides a first auxiliary condenser 22 connected in series with the main condenser 21 in the air outlet duct 13. The auxiliary condenser 22 provides auxiliary heat exchange, which increases the heat exchange area. When air enters the compressor chamber 12 through the air inlet duct 11, it first exchanges heat with the main condenser 21 and continues to exchange heat with the first auxiliary condenser 22 when it is discharged from the air outlet duct 13. This allows the air entering the bottom of the refrigerator to fully exchange heat with the high-temperature refrigerant, enhancing the heat dissipation effect of the refrigerant flowing in the condenser 20.

[0046] like Figure 2 , Figure 3 and Figure 5 As shown, the first auxiliary condenser 22 includes a first condenser tube 221, and the first auxiliary condenser 22 is connected in series with the main condenser 21 through the first condenser tube 221. The first condenser tube 221 includes multiple first condenser straight tube sections 222, which are arranged sequentially at intervals along the depth direction y of the refrigerator, and are connected end to end sequentially along the length direction x of the refrigerator. Here, the number of first condenser straight tube sections 222 can be configured as 8, 10, 13, 15, 18, 20, etc.

[0047] In this embodiment, the first auxiliary condenser 22 is configured as a finned condenser 20, and the first auxiliary condenser 22 further includes a plurality of first fins 223. The plurality of first fins 223 are arranged sequentially at intervals along the length x of the refrigerator, and each first fin 223 is simultaneously connected to a plurality of first condensing straight pipe sections 222. Thus, by providing a plurality of first fins 223, the effective heat dissipation surface area of ​​the first auxiliary condenser 22 can be increased, thereby enhancing the heat dissipation effect of the first auxiliary condenser 22. Here, the number of first fins 223 can be 5, 7, 8, 9, etc.

[0048] In one embodiment, the flow area of ​​the air outlet duct 13 is set to A1, and the cross-sectional area of ​​the first auxiliary condenser 22 perpendicular to the air outlet direction of the air outlet duct 13 is set to A2, wherein 12%A1≤A2≤30%A1. By limiting 12%A1≤A2≤30%A1, the heat dissipation performance of the condenser 20 and the airflow resistance of the air outlet duct 13 can be balanced. This ensures that after the first auxiliary condenser 22 is installed, the condenser 20 has sufficient heat dissipation area without excessively blocking the air outlet duct 13, preventing insufficient airflow and maintaining the heat dissipation stability of the refrigerator bottom assembly 100.

[0049] Preferably, the air outlet duct 13 has a dimension C1 and a height H1 along the length x of the refrigerator, and the first auxiliary condenser 22 has a dimension c1 and a height h1 along the length x of the refrigerator, with 0.6C1 ≥ c1 ≥ 0.4C1 (e.g., c1 = 0.4C1, c1 = 0.5C1, c1 = 0.6C1, etc.); and 0.5H1 ≥ h1 ≥ 0.3H1 (e.g., h1 = 0.3H1, h1 = 0.4H1, h1 = 0.5H1, etc.). Thus, by limiting the length and height of the air outlet duct 13 relative to its length and height, the contact area between the condenser 20 and the air entering the air inlet duct 11 can be increased, thereby ensuring effective heat dissipation.

[0050] like Figure 2 , Figure 4 and Figure 6 As shown, the condenser 20 also includes a second auxiliary condenser 23, which is located in the area where the air inlet channel 11 is located, and is connected in series with the main condenser 21. Here, the second auxiliary condenser 23 can be a wire tube condenser, a finned condenser, or a plate tube condenser, etc.

[0051] In one embodiment, the second auxiliary condenser 23 includes a second condenser tube 231, and the second auxiliary condenser 23 is connected in series with the main condenser 21 through the second condenser tube 231. The second condenser tube 231 includes multiple second condenser straight tube sections 232, which are arranged sequentially at intervals along the depth direction y of the refrigerator, and are connected end to end in the length direction x of the refrigerator. By providing the second auxiliary condenser 23, the total heat dissipation area can be further increased, thereby improving the overall heat exchange efficiency of the bottom assembly 100 of the refrigerator. Here, the first condenser straight tube section 222 can be configured to have 8, 10, 13, 15, 18, 20, etc.

[0052] In one embodiment, the second auxiliary condenser 23 further includes a plurality of second fins 233, which are arranged sequentially at intervals along the length x of the refrigerator, and each second fin 233 is simultaneously connected to a plurality of second condenser straight pipe sections 232. By providing a plurality of second fins 233, the effective heat dissipation surface area of ​​the second auxiliary condenser 23 can be increased, thereby enhancing the heat dissipation effect of the second auxiliary condenser 23. Here, the number of first fins 223 can be 5, 7, 8, 9, etc.

[0053] In one embodiment, the flow area of ​​the air inlet channel 11 is set to B1, and the cross-sectional area of ​​the second auxiliary condenser 23 perpendicular to the air inlet direction of the air inlet channel 11 is set to B2, wherein 12%B1≤B2≤30%B1. By limiting 12%B1≤B2≤30%B1, the heat dissipation performance of the condenser 20 and the airflow resistance of the air inlet channel 11 can be balanced. This ensures that after the second auxiliary condenser 23 is installed, the condenser 20 has sufficient heat dissipation area, but the air inlet channel 11 is not excessively blocked, preventing insufficient airflow and thus maintaining the heat dissipation stability of the refrigerator bottom assembly 100.

[0054] Preferably, the air inlet channel 11 has a dimension of C2 and a height of H2 along the length x of the refrigerator, and the second auxiliary condenser 23 has a dimension of c2 and a height of h2 along the length x of the refrigerator, with 0.6C2 ≥ c2 ≥ 0.4C2 (e.g., c2 = 0.4C2, c2 = 0.5C2, c2 = 0.6C2); and 0.5H2 ≥ h2 ≥ 0.3H2 (e.g., h2 = 0.3H2, h2 = 0.4H2, h2 = 0.5H2). Thus, by limiting the ratio of the length and height of the second auxiliary condenser 23 to the length and height of the air outlet channel 13, the contact area between the condenser 20 and the air entering the air outlet channel 13 can be increased, thereby ensuring heat dissipation.

[0055] In one embodiment, the refrigerator bottom assembly 100 further includes a compressor 30, which is disposed in the area where the compressor compartment 12 is located; a first auxiliary condenser 22 is connected to and communicates with the compressor 30; a second auxiliary condenser 23 includes a refrigerant connecting pipe 234, which passes through the refrigerator bottom body 10 in the refrigerator height direction z and extends outward.

[0056] like Figure 1 and Figure 4As shown, the refrigerator bottom assembly 100 also includes a condenser fan 40, which is located on one side of the main condenser 21. The condenser fan 40 is used to draw in ambient cooling air from the air inlet channel 11, so that the airflow passes through the surfaces of the second auxiliary condenser 23, the main condenser 21 and the first auxiliary condenser 22 in sequence and undergoes heat exchange in sequence. Finally, the heated air is discharged from the air outlet channel 13, thereby achieving efficient cooling of the refrigerant.

[0057] This application also provides the following technical solutions:

[0058] A refrigerator includes a bottom assembly 100 as described in any of the above embodiments. It should be explained that the refrigeration cycle within the refrigerator is a closed loop. For example, the connection method of the refrigeration components is as follows: the compressor 30 is connected in series with the first auxiliary condenser 22, the main condenser 21, and the second auxiliary condenser 23, and then connected to the throttling device and evaporator within the refrigerator. The throttling device and evaporator are then connected to the compressor 30. This type of structure is common in the prior art and will not be elaborated upon here.

[0059] The refrigerator bottom component 100 can be controlled by a voice module, which is equipped with a controller, a voice receiving module, and a voice parsing module. The voice receiving module receives user commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the refrigerator bottom component 100 to perform corresponding operations, thereby realizing intelligent control of the refrigerator bottom component 100 and improving the user experience.

[0060] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
