Description

Technical Field

[0001] This application relates to the field of refrigerator technology, and in particular to a top-mounted module and a refrigerator. Background Technology

[0002] The most common layout for refrigerators on the market is to place the compressor compartment at the top of the refrigerator and the refrigeration system, including the evaporator, at the back of the refrigeration compartment. Specifically, the evaporator is integrated with the cabinet and the refrigeration pipes are welded to the compressor and condenser inside the compressor compartment.

[0003] However, placing the evaporator at the back of the refrigeration compartment occupies internal space, resulting in a complex internal structure. Furthermore, because the piping layout and installation of evaporators differ between refrigerators, the refrigeration system suffers from poor versatility, and refrigerator production lacks flexibility. Utility Model Content

[0004] Therefore, it is necessary to provide a top-mounted module and refrigerator to improve the versatility of the refrigerator refrigeration system and the flexibility of refrigerator production, and to avoid the refrigeration system taking up space inside the cabinet.

[0005] A top-mounted module is used to install on the top of a refrigerator. The top-mounted module includes a compressor compartment, a compressor, a condenser, a refrigeration evaporator, and a freezing evaporator. The compressor, condenser, refrigeration evaporator, and freezing evaporator are installed in the compressor compartment and connected to form a refrigeration cycle loop. A first air passage and a second air passage are formed in the compressor compartment. The bottom wall of the compressor compartment has a first air inlet, a first air outlet, a second air inlet, and a second air outlet. The first air inlet and the first air outlet are used to connect the refrigerator body and the first air passage, respectively. The refrigeration evaporator is located on the first air passage. The second air inlet and the second air outlet are used to connect the refrigerator body and the second air passage, respectively. The freezing evaporator is located on the second air passage.

[0006] In one embodiment, the top-mounted module further includes an insulation shell installed inside the compressor chamber, which divides the interior of the compressor chamber into a first space and a second space; the first air duct and the second air duct are located in the first space, and the compressor and condenser are located in the second space.

[0007] In one embodiment, the first space and the second space are arranged along the width direction y of the cabinet, and the refrigeration evaporator and the freezing evaporator are distributed at intervals along the length direction x of the cabinet within the first space.

[0008] In one embodiment, the compressor compartment has an opening on the side along the width direction y of the housing, and the compressor compartment is fitted over the outside of the insulation shell through the opening.

[0009] In one embodiment, the insulation shell has an insulation cavity and a notch. The insulation cavity has an opening facing the bottom wall of the press chamber and is used to form a first space with the inner wall of the press chamber. The notch is opened at one end of the insulation shell along the width direction y of the shell and is used to form a second space with the inner wall of the press chamber.

[0010] In one embodiment, a first air duct is provided in the first space. The first air duct extends in a U-shape, and both ends of the first air duct extend from the bottom wall of the compressor chamber through a first air inlet and a first air outlet, respectively. The refrigerated evaporator is installed inside the first air duct so that a first air path is formed inside the first air duct.

[0011] In one embodiment, a second air duct and a third air duct are provided in the first space at intervals. One end of the second air duct is connected to the first space and the other end is connected to the second air inlet. One end of the third air duct is connected to the first space and the other end is connected to the second air outlet. The refrigeration evaporator is located in the second air duct so that the second air duct is connected to the third air duct through the first space to form a second air path.

[0012] In one embodiment, a first fan is provided in the first air path to provide suction air from the first air inlet to the refrigerated evaporator; and / or, a second fan is provided in the second air path to provide suction air from the second air inlet to the second air outlet.

[0013] A refrigerator includes a cabinet and a top-mounted module as described in any of the above embodiments. The top-mounted module is installed on the top of the cabinet along the height direction z. The cabinet has a refrigerator compartment and a freezer compartment inside. A first air inlet and a first air outlet are respectively connected to the refrigerator compartment, and a second air inlet and a second air outlet are respectively connected to the freezer compartment.

[0014] In one embodiment, the refrigerator compartment and the freezer compartment are arranged along the height direction z of the cabinet; or, the refrigerator compartment and the freezer compartment are arranged along the length direction x of the cabinet.

[0015] Compared with existing technologies, the top-mounted module and refrigerator provided in this application, by integrating the refrigeration evaporator and the freezing evaporator into the compressor compartment, can free up internal space in the cabinet, thereby simplifying the internal structure of the cabinet. By providing a first air inlet, a first air outlet, a second air inlet, and a second air outlet on the bottom wall of the compressor compartment, each of these outlets serves as a standard interface. When the top-mounted module is matched with different cabinets, only interfaces corresponding to the first air inlet, first air outlet, second air inlet, and second air outlet need to be reserved in different cabinets. The internal air duct structure of the cabinet can be freely configured. This improves the versatility of the top-mounted module, and the top-mounted module and different cabinets can be manufactured and assembled separately, thereby enhancing the flexibility of refrigerator production.

[0031] Please see Figures 1 to 4This application provides a top-mounted module 100, which is installed on the top of the refrigerator body 200. The top-mounted module 100 includes a compressor compartment 10, a compressor 20, a condenser 30, a refrigerator evaporator 40, and a freezer evaporator 50. The compressor 20, condenser 30, refrigerator evaporator 40, and freezer evaporator 50 are installed inside the compressor compartment 10, and the compressor 20, condenser 30, refrigerator evaporator 40, and freezer evaporator 50 are connected to form a refrigeration cycle loop; the compressor compartment 10... The compressor chamber 10 has a first air passage 11 and a second air passage 12. The bottom wall of the compressor chamber 10 has a first air inlet 13, a first air outlet 14, a second air inlet 15 and a second air outlet 16. The first air inlet 13 and the first air outlet 14 are used to connect the chamber 200 and the first air passage 11, respectively. The refrigerated evaporator 40 is located on the first air passage 11. The second air inlet 15 and the second air outlet 16 are used to connect the chamber 200 and the second air passage 12, respectively. The refrigerated evaporator 50 is located on the second air passage 12.

[0032] Understandably, by integrating the refrigeration evaporator 40 and the freezing evaporator 50 into the compressor compartment 10, internal space of the cabinet 200 can be freed up, thereby simplifying the internal structure of the cabinet 200. By providing a first air inlet 13, a first air outlet 14, a second air inlet 15, and a second air outlet 16 on the bottom wall of the compressor compartment 10, these interfaces serve as standard interfaces. When the top module 100 is matched with different cabinets 200, only interfaces corresponding to the first air inlet 13, the first air outlet 14, the second air inlet 15, and the second air outlet 16 need to be reserved in different cabinets 200. The internal air duct structure of the cabinet 200 can be freely configured. This improves the versatility of the top module 100, and allows for separate production and assembly of the top module 100 and different cabinets 200, thus enhancing the flexibility of refrigerator production.

[0033] Among them, such as Figure 7 As shown, the compressor 20, condenser 30, refrigerator evaporator 40 and freezer evaporator 50 are connected by pipes 90 to form a refrigeration cycle loop. This part is the conventional technology of the refrigerator refrigeration system and will not be described in detail here. The cabinet 200 has a refrigerator compartment 210 and a freezer compartment 220 inside. The first air inlet 13 and the first air outlet 14 are respectively connected to the refrigerator compartment 210, and the second air inlet 15 and the second air outlet 16 are respectively connected to the freezer compartment 220.

[0034] In one embodiment, such as Figure 4 and Figure 6As shown, the top-mounted module 100 also includes an insulation shell 60, which is installed inside the compressor compartment 10, dividing the interior of the compressor compartment 10 into a first space 17 and a second space 18. The first air duct 11 and the second air duct 12 are located in the first space 17, while the compressor 20 and the condenser 30 are located in the second space 18. That is, the refrigeration evaporator 40 and the freezing evaporator 50 are located in the first space 17, and the compressor 20 and the condenser 30 are located in the second space 18. This separates the heat dissipation portion (condenser 30) and the cooling portion (refrigeration evaporator 40 and freezing evaporator 50) in the top-mounted module 100, thereby improving the cooling performance of the top-mounted module 100. The insulation shell 60 can be made of polyurethane, rock wool, or phenolic foam, etc.

[0035] In one embodiment, the first space 17 and the second space 18 are arranged along the width direction y of the housing 200, and the refrigeration evaporator 40 and the freezing evaporator 50 are distributed at intervals along the length direction x of the housing 200 within the first space 17.

[0036] Specifically, the first space 17 can be located in front of the second space 18 along the width direction y of the cabinet 200, or the second space 18 can be located in front of the first space 17 along the width direction y of the cabinet 200. The refrigeration evaporator 40 can be located to the left of the freezing evaporator 50 within the first space 17 along the length direction y of the cabinet 200, or the freezing evaporator 50 can be located to the left of the refrigeration evaporator 40 within the first space 17 along the length direction y of the cabinet 200. The specific arrangement can be freely adjusted according to requirements.

[0037] In one embodiment, such as Figure 6 As shown, the press chamber 10 has an opening 19 on the side along the width direction y of the housing 200, and the press chamber 10 is fitted onto the outside of the insulation shell 60 through the opening 19. This facilitates the assembly and disassembly of the insulation shell 60 and the press chamber 10.

[0038] In one embodiment, for example, an opening 19 is formed on the front side of the compressor compartment 10 along the width direction y of the housing 200.

[0039] Specifically, in one embodiment, such as Figure 8 As shown, the insulation shell 60 has an insulation cavity 601 and a notch 61. The insulation cavity 601 has an opening 611 facing the bottom wall of the compressor chamber 10, and the insulation cavity 601 is used to enclose a first space 17 with the inner wall of the compressor chamber 10. The notch 61 is opened at one end of the insulation shell 60 along the width direction y of the housing 200, and the notch 61 is used to enclose a second space 18 with the inner wall of the compressor chamber 10. It can be understood that the opening 611 is used for the refrigeration evaporator 40 and the freezing evaporator 50 to be installed in the insulation cavity.

[0040] In one embodiment, such as Figure 5 As shown, the compressor compartment 10 has multiple heat dissipation holes 191 on its side wall opposite to the opening 19. These holes 191 connect the second space 18 to the external environment to facilitate the dissipation of heat generated by the condenser 30 in the second space 18. The condenser 30 can be a finned condenser. Optionally, a condensing fan can also be installed in the second space 18 to further promote heat dissipation from the condenser 30.

[0041] In one embodiment, such as Figure 2 As shown, a first air duct 70 is provided in the first space 17. The first air duct 70 extends in a U-shape, and its two ends extend from the bottom wall of the compressor compartment 10 through the first air inlet 13 and the first air outlet 14, respectively. The refrigeration evaporator 40 is installed inside the first air duct 70, so that a first air passage 11 is formed inside the first air duct 70. In this way, the air in the refrigeration compartment 210 enters the first air duct 70 through the first air inlet 13, and then exchanges heat with the refrigeration evaporator 40 to form cold air. The cold air is then sent to the refrigeration compartment 210 through the first air outlet 14 along the first air duct 70.

[0042] Furthermore, in one embodiment, a first fan 111 is provided on the first air passage 11. The first fan 111 is used to provide suction air from the first air inlet 13 to the refrigeration evaporator 40, which is beneficial to improving the refrigeration efficiency of the refrigeration evaporator 40.

[0043] In one embodiment, such as Figure 3 and Figure 4 As shown, the first space 17 is also equipped with a second air duct 81 and a third air duct 82 spaced apart. One end of the second air duct 81 is connected to the first space 17, and the other end is connected to the second air inlet 15. One end of the third air duct 82 is connected to the first space 17, and the other end is connected to the second air outlet 16. The evaporator 50 is located inside the second air duct 81, so that the second air duct 81 connects to the third air duct 82 through the first space 17 to form a second air path 12. In this way, the air in the freezer compartment 220 enters the first space 17 through the second air duct 81 and exchanges heat with the evaporator 50 in the second air duct 81 to form cold air. The cold air enters the freezer compartment 220 through the third air duct 82. Since the freezer compartment 220 requires a larger cooling capacity than the refrigerator compartment 210, by setting the second air duct 81 and the third air duct 82, the heat exchange space of the air in the freezer compartment 220 in the first space 17 can be increased, thereby matching the cooling capacity requirement of the freezer compartment 220. Specifically, the second air duct 81 and the third air duct 82 are arranged at intervals along the width direction y of the housing 200.

[0044] Furthermore, in one embodiment, a second fan 121 is provided on the second air passage 12, and the second fan 121 is used to provide suction air from the second air inlet 15 to the second air outlet 16. This is beneficial to improving the cooling efficiency of the refrigeration evaporator 50.

[0045] like Figure 1 As shown, this application also provides a refrigerator, which includes a cabinet 200 and a top module 100 as described in any of the above embodiments. The top module 100 is installed on the top of the cabinet 200 along the height direction z of the cabinet 200.

[0046] Specifically, the top module 100 and the housing 200 can be connected by screws, or the top module 100 and the housing 200 can be snapped together.

[0047] In one embodiment, the refrigerator compartment 210 and the freezer compartment 220 are arranged along the height direction z of the cabinet 200. Alternatively, in another embodiment, the refrigerator compartment 210 and the freezer compartment 220 are arranged along the length direction x of the cabinet 200.

[0048] 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.

[0049] 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.
