[0023] Fig. 1 is a front upper axial side view of a bottom local structure of a refrigerator having a heat dissipation compartment at the bottom according to some embodiments of the present invention. Fig. 2 is a rear upper axial side view of the bottom local structure shown in Fig. 1. Fig. 3 is a cross-sectional view of the bottom local structure in Fig. 2 along the AA direction.

[0024] As shown in FIGS. 1 to 3, in some embodiments of the present invention, a refrigerator mainly includes a cabinet 1, a compressor 2, a blower assembly 3, an evaporation dish 4, and an evaporator 5.

[0025] Continuing to refer to FIGS. 1 to 3, the cabinet 1 defines a storage compartment 11, a heat dissipation compartment 12, and a freezer compartment 13. The number of storage compartments 11 is not limited to two as shown in FIGS. 1 and 2, and may be one or more as needed. When there is one storage compartment 11, the storage compartment 11 may be a freezer compartment, a temperature-variable compartment, or a refrigerator compartment. When there are two or more storage compartments 11, the multiple storage compartments 11 may include at least one or more of a freezer compartment, a temperature-variable compartment, and a refrigerator compartment. When specifically implementing the technical solution of the present invention, those skilled in the art can determine the number of storage compartments 11 and their functions as needed.

[0026] Continuing to refer to FIGS. 1 to 3, a heat dissipation compartment 12 is disposed at the rear bottom of the cabinet 1. In some embodiments, a freezer compartment 13 for disposing an evaporator is provided at the bottom of the storage compartment 11. That is, the freezer compartment 13 is disposed in front of and above the heat dissipation compartment 12, thereby realizing a bottom-mounted evaporator refrigerator. The freezer compartment 13 occupies the bottom area of ​​the inner liner, elevating the storage compartment 11 and reducing the amount of bending required when a user accesses and manipulates items in the storage compartment 11, improving the user experience. The evaporator 5 is mounted within the freezer compartment 13 and is used to supply cool air into the storage compartment 11.

[0027] To divide the space, the heat dissipation compartment 12 is divided into a first heat dissipation cavity 121 and a second heat dissipation cavity 122 by the blower assembly 3, and different components are arranged in each cavity.

[0028] FIG. 4 is a schematic diagram of the distribution of main components within the heat dissipation compartment 12 of a refrigerator according to some embodiments of the present invention, in which a compressor 2, a blower assembly 3, and an evaporator dish 4 are arranged in that order from left to right along the horizontal direction of the refrigerator within the heat dissipation compartment 12.

[0029] The blower assembly 3 is disposed in the horizontal middle of the heat dissipation compartment 12, which is divided into a first heat dissipation cavity 121 and a second heat dissipation cavity 122 along the horizontal direction of the cabinet 1, with a fan fixing structure provided on the side of the blower assembly 3 facing the first heat dissipation cavity 121 and a condenser fixing structure provided on the side of the blower assembly 3 facing the second heat dissipation cavity 122. The compressor 2 and the evaporator dish 4 are disposed in the first heat dissipation cavity 121 and the second heat dissipation cavity 122, respectively.

[0030] The compressor 2 is located in the first heat dissipation cavity and is connected to a condenser (not shown in FIG. 4, blocked by the blower assembly 3) via a refrigeration line (not shown).

[0031] The evaporator dish 4 is mounted in the second heat dissipation cavity 122 and is used to receive water discharged from a drain pipe 41 connected to the freezer compartment 13. The drain pipe 41 extends from the freezer compartment 13 to the heat dissipation compartment 12. That is, the upper end of the drain pipe 41 communicates with the bottom of the freezer compartment 13, and the lower end of the drain pipe 41 extends to the evaporator dish 4. The drain pipe 41 is used to discharge thawed water from the refrigerator into the evaporator dish 4, and the evaporator dish 4 evaporates the water into the ambient air.

[0032] The bottom plate of heat dissipation compartment 12 is provided with a heat dissipation air inlet 321 and a heat dissipation air outlet 322 at the front of first heat dissipation cavity 121 and second heat dissipation cavity 122, respectively. Ambient air from below the refrigerator enters heat dissipation compartment 12 through heat dissipation air inlet 321, first exchanges heat with compressor 2, passes through the heat dissipation fan and condenser, promotes the evaporation of water in evaporator pan 4, and is then discharged downward through heat dissipation air outlet 322. This smooths the heat dissipation airflow, improving the heat dissipation efficiency of each component. A partition member is further provided on the underside of the refrigerator's bottom plate to separate heat dissipation air inlet 321 and heat dissipation air outlet 322, preventing the discharged air from being re-inhaled after heat dissipation.

[0033] The bottom plate of heat dissipation compartment 12 is also called the compressor support plate, and a first roller 51 and a second roller 52 are arranged on both the left and right sides thereof. That is, first roller 51 is arranged on the bottom plate of heat dissipation compartment 12 on the opposite side of blower assembly 3 with compressor 2 in between, and second roller 52 is arranged on the bottom plate of heat dissipation compartment 12 on the opposite side of blower assembly 3 with evaporator dish 4 in between. First roller 51 and second roller 52 are used to roll the refrigerator when it is moved.

[0034] FIG. 5 is an exploded view of the assembled structure of the blower assembly 3, the heat dissipation fan 32, and the condenser 31 of the refrigerator according to some embodiments of the present invention.

[0035] The blower assembly 3, heat dissipation fan 32, and condenser 31 are pre-assembled to form a single unit, forming a blower structure for passing the heat dissipation airflow, so that the airflow flows through the condenser 31 as a whole, improving the heat dissipation efficiency, while also making the structure more compact and simplifying the assembly process.

[0036] The blower assembly 3 is disposed in the horizontal middle of the heat dissipation compartment 12, which is divided into a first heat dissipation cavity 121 and a second heat dissipation cavity 122 along the horizontal direction of the cabinet 1. A fan fixing structure is provided on the side of the blower assembly 3 facing the first heat dissipation cavity 121, and a condenser fixing structure is provided on the side of the blower assembly 3 facing the second heat dissipation cavity 122. That is, the fan fixing structure faces the compressor 2, and the condenser fixing structure faces the evaporator dish 4. The blower assembly 3 is disposed in the front-to-rear direction. The fan fixing structure and the condenser fixing structure may each be engaging structures, and are engaged with the housing of the heat dissipation fan 32 and the condenser 31, respectively.

[0037] The heat dissipation fan 32 is attached to the fan fixing structure and is used to promote the formation of a heat dissipation airflow that enters from outside the cabinet, passes through the first heat dissipation cavity 121 and the second heat dissipation cavity 122, and then is discharged from the cabinet. The condenser 31 is attached to the condenser fixing structure and is cooled by the heat dissipation airflow. The airflow passes through the compressor 2, condenser 31, and evaporator pan 4 in sequence, dissipating heat from each component in turn, improving heat dissipation efficiency.

[0038] The blower assembly 3 is provided with a fan fixing structure and a condenser fixing structure on both sides, and the heat dissipation fan 32 and condenser 31 are assembled to form an integrated blower structure, which reduces the space occupied by the heat dissipation fan 32 and condenser 31. The arrangement of components within the heat dissipation compartment is more compact, providing more space for the compressor 2 and evaporator pan 4, which is advantageous for improving heat dissipation efficiency. Compared with the prior art solution of installing the condenser above the evaporator pan 4, the structure of this embodiment reduces the height of the heat dissipation compartment 12.

[0039] The blower assembly 3 is composed of a bracket body 33 and a windshield 34. The bracket body 33 has a rectangular cylindrical shape and extends laterally, i.e., left-right, through the cabinet 1. The cylindrical shape of the bracket body is used to allow the heat dissipation airflow to pass through. The windshield 34 extends from the front end of the bracket body 33 and seals off the front areas of the first heat dissipation cavity 121 and the second heat dissipation cavity 122, preventing the heat dissipation airflow from returning and allowing the airflow to be blown out only through the cylindrical portion of the bracket body 33.

[0040] A microchannel condenser is preferably used as the condenser 31, which saves space occupied by the condenser 31 and makes it easy to fit with the bracket body 33. The direction of the gaps between the microchannels of the microchannel condenser is aligned with the direction of the heat dissipation airflow, so that all the heat dissipation airflow must pass through the condenser 31, improving the heat exchange efficiency.

[0041] During assembly, the condenser 31, the heat dissipation fan 32 and the blower assembly 3 are first pre-assembled to form an integrated pre-assembled assembly, and then the whole can be installed inside the cabinet 1.

[0042] 6 is a structural diagram of an evaporating dish 4 in a refrigerator according to some embodiments of the present invention. The evaporating dish 4 is disposed within the heat dissipation compartment 12, and is provided with a plurality of connecting pipes 42 along the width of the refrigerator. Each of the plurality of connecting pipes 42 is adapted to the position of a drain pipe 41 of the cabinet 1, which has a different width. One of the plurality of connecting pipes 42 that faces the position of the drain pipe 41 is used to connect to the drain pipe 41, and the evaporating dish 4 receives water drained from the drain pipe 41.

[0043] The evaporating dish 4 is provided with an insertion prevention baffle 43 in front of the plurality of connecting pipe sections 42. The insertion prevention baffle 43 is provided with limiting slots 431 that correspond one-to-one to the plurality of connecting pipe sections 42. The limiting slots 431 are used to fix the drain pipe 41, preventing the drain pipe 41 from shaking while increasing the supporting strength of the drain pipe 41.

[0044] 6 shows two connecting pipes 42, which are suitable for two storage units with different widths. In specific implementation, those skilled in the art can set the number of connecting pipes 42 as needed and use the connecting pipes 42 to accommodate storage units with different dimensions.

[0045] The following description will be given taking two typical refrigerator body widths, 905 mm and 830 mm, as examples. Figure 7 is a comparison diagram of the layout of the heat dissipation compartment 12 for two body sizes of refrigerators according to some embodiments of the present invention. In Figure 7, the upper part shows a first-size body with a width of 905 mm, and the lower part shows a first-size body with a width of 830 mm. Here, the width of the bottom plate of the heat dissipation compartment of the first-size body is 895 mm, and the width of the bottom plate of the heat dissipation compartment of the second-size body is 820 mm, and the distance between the centers of the two connecting pipe parts 42 along the lateral direction of the refrigerator is 29 mm.

[0046] The projection of the drain pipe 41 on the bottom plate of the heat dissipation compartment 12 is a straight line along the front-to-rear direction of the cabinet 1, and the drain pipe 41 is inclined downward from front to rear, allowing water to be drained by gravity into the evaporator tray 4. The position of the drain pipe 41 relative to the cabinet 1 is determined according to the structure of the freezer compartment 13 and the position of the drain outlet of the freezer compartment 13. To facilitate drainage, the drain pipe 41 can be shortened as much as possible and placed close to the lateral center of the cabinet 1.

[0047] Using the center line of the projection of the drain pipe 41 on the bottom plate of the heat dissipation compartment 12 as a reference, the bottom plate of the heat dissipation compartment 12 of the second-dimension body is set back 37.5 mm toward the center on both sides compared to the bottom plate of the heat dissipation compartment 12 of the first-dimension body. The first roller 51 of the second-dimension body is set back 29 mm inward compared to the first roller 51 of the first-dimension body. The compressor 2, blower assembly 3, and evaporator dish 4 of the second-dimension body are each displaced 29 mm toward the second heat dissipation cavity, i.e., shifted 29 mm to the right, compared to the corresponding components of the first-dimension body.

[0048] That is, the 830-width and 905-width cabinets are arranged along the horizontal direction of the bottom plate of the heat dissipation compartment 12, with the position of the drain pipe 41 as the reference origin (lateral movement of the drain pipe 41 to the left or right affects the installation height of the evaporator 5 in a bottom-mounted evaporator refrigerator, and changes in the height of the evaporator 5 affect important parameters such as the drain angle of the drain pipe 51, so the height of the evaporator 5 remains relatively constant even when the width of a bottom-mounted evaporator refrigerator changes). The second-size cabinet (830 width) has two sides reduced by 37.5 mm based on the bottom plate of the first-size cabinet (905 width), and the first roller 51 of the second-size cabinet is displaced 29 mm to the left based on the second-size cabinet, and cannot be displaced at 37.5 mm to prevent the roller from interfering with the compressor 2 in the vertical direction.

[0049] Correspondingly, the compressor 2, blower assembly 3, and evaporator dish 4 of the second-dimension container are all displaced 29 mm to the right with respect to the second container. The left-right distance between the two connecting pipes 42 of the evaporator dish 4 of the second-dimension container is also 29 mm.

[0050] Based on the above description, as will be understood by those skilled in the art, by arranging the compressor 2, blower assembly 3 and evaporator dish 4 sequentially in the left and right direction of the cabinet 1 within the heat dissipation compartment 12, and providing multiple connecting pipe sections 42 on the evaporator dish 4, it can be adapted to cabinets of different widths, thereby achieving versatility and significantly reducing component costs and development costs.

[0051] Although the technical solutions of the present invention have been described above in conjunction with the above-mentioned embodiments, those skilled in the art should understand that the protection scope of the present invention is not limited to these specific embodiments. As long as it does not deviate from the technical principle of the present invention, those skilled in the art can disassemble and combine the technical solutions in the above-mentioned embodiments, and make equivalent modifications or substitutions to the related technical features. Any modifications, equivalent substitutions, and improvements made within the technical idea and / or technical principle of the present invention shall all be included in the protection scope of the present invention.
