Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of refrigeration equipment, and in particular relates to a refrigerator with a heat dissipation compartment at a bottom of the refrigerator.

BACKGROUND

[0002] In some prior art refrigerators, especially built-in refrigerators, a condenser, a compressor, and an evaporating dish are arranged in a heat dissipation compartment at the bottom of a cabinet. A heat dissipation fan draws in ambient air from the outside of the refrigerator and induces the air to flow in the heat dissipation compartment, convectively dissipating heat to the condenser and the compressor through convection heat dissipation.

[0003] For the above-mentioned refrigerators, the space of the heat dissipation compartment is limited, and a count of heat generating components arranged is relatively large, resulting in a messy arrangement of the components in the heat dissipation compartment, occupying a large space, and lowering the heat dissipation efficiency. Additionally, the assembly process becomes complicated and time-consuming as numerous parts need to be assembled separately, leading to a decrease in production efficiency.

[0004] For an evaporator bottom-mounted refrigerator, the height of the heat dissipation compartment is about 20 mm smaller than that of a conventional refrigerator, exacerbating the aforementioned technical issue.

[0027] FIG. 1 is a front upper axonometric view of a partial bottom structure of a refrigerator with a heat dissipation compartment at a bottom of the refrigerator according to some embodiments of the present disclosure; FIG. 2 is a rear upper axonometric view of the partial bottom structure illustrated in FIG. 1; FIG. 3 is the sectional view of the partial bottom structure shown in FIG. 2 along the A-A direction.

[0028] As shown in FIG. 1 to FIG. 3, in some embodiments of the present disclosure, a refrigerator mainly includes a cabinet 1, a compressor 2, a fixed bracket 3, an evaporating dish 4, and an evaporator 5.

[0029] Continuing to refer to FIG. 1 to FIG. 3, the cabinet 1 defines one or more storage compartments 11, a heat dissipation compartment 12, and a cooling chamber 13. A count of the storage compartments 11 is not limited to the two shown in FIG. 1 and FIG. 2, and may be any other number, such as one, three, five, eight, or the like. When there is one storage compartment 11, the storage compartment 11 may be a freezer compartment, a variable temperature compartment, or a refrigeration compartment. When there are two or more storage compartments 11, the multiple storage compartments 11 comprise at least one of a freezer compartment, a variable temperature compartment, and a refrigeration compartment. In the specific implementation of the technical solution of the present disclosure, the person skilled in the art may configure the count and functions of the storage compartments 11 as desired.

[0030] Continuing with reference to FIG. 1 to FIG. 3, a rear bottom of the cabinet 1 has a heat dissipation compartment 12. In some embodiments, the cooling chamber 13 may be provided at front of the heat dissipation compartment, thereby realizing a evaporator bottom-mounted refrigerator. The cooling chamber 13 occupies a bottom area of the inner liner, elevating the storage compartment 11, reducing the degree of bending for users when picking up and placing items in the storage compartment 11, and enhancing the user's experience. The evaporator 5 is installed inside the cooling chamber 13 to provide cooling to the interior of the storage compartment 11.

[0031] The heat dissipation compartment 12 is divided into a first heat dissipation chamber 121 and a second heat dissipation chamber 122 by the fixed bracket 3, in order to divide the space for arranging the different components respectively.

[0032] FIG. 4 is a schematic diagram illustrating the distribution of main components in the heat dissipation compartment 12 of a refrigerator according to some embodiments of the present disclosure. The compressor 2, the fixed bracket 3, and the evaporating dish 4 are arranged in the heat dissipation compartment 12 sequentially along a transverse direction of the refrigerator from left to right.

[0033] The fixed bracket 3 is provided in the middle of the heat dissipation compartment 12 along the transverse direction, divides the heat dissipation compartment 12 into the first heat dissipation chamber 121 and the second heat dissipation chamber 122 along the transverse direction of the cabinet 1. A fan fixing structure is provided on one side of the fixed bracket 3 facing the first heat dissipation chamber 121, and a condenser fixing structure is provided on one side of the fixed bracket 3 facing the second heat dissipation chamber 122. The compressor 2 and the evaporating dish 4 are provided in the first and second heat dissipation chamber 121 and 122, respectively.

[0034] The compressor 2 is located in the first heat dissipation chamber and is connected to a condenser, which is obscured by the fixed bracket 3 and not shown in FIG. 4, via a refrigeration line not shown in FIG. 4.

[0035] The evaporating dish 4 is installed in the second heat dissipation chamber 122 to receive water discharged from a drain pipe 41 connected to the cooling chamber 13. An upper end of the drain pipe 41 is connected to a bottom of the cooling chamber 13, and a lower end of the drain pipe 41 extends above the evaporating dish 4. The drain pipe 41 is used to discharge defrost water of the refrigerator into the evaporating dish 4, and the evaporating dish 4 is used to evaporate the water into the ambient air.

[0036] A bottom plate of the heat dissipation compartment 12 is provided with a heat dissipation air inlet port 321 and a heat dissipation air exhaust port 322 at front portions of the first heat dissipation chamber 121 and the second heat dissipation chamber 122, respectively. The ambient air below the refrigerator enters the heat dissipation compartment 12 from the heat dissipation air inlet port 321, exchanges heat with the compressor 2, and then accelerates the evaporation of water in the evaporating dish 4 after passing through the heat dissipation fan and the condenser, and is then discharged back to the lower part of the refrigerator from the heat dissipation air exhaust port 322. The heat dissipation airflow is smooth, which improves the heat dissipation efficiency of each component. Isolation members for isolating the heat dissipation air inlet port 321 and the heat dissipation air exhaust port 322 may be further provided on a lower surface of the bottom plate of the refrigerator to avoid the discharged heat dissipation air from being reabsorbed.

[0037] The construction of the fixed bracket 3 and the assembly structure of the fixed bracket 3 with a heat dissipation fan 32 and a condenser 31 are described below in conjunction with FIG. 5 - FIG. 9. FIG. 5 is a schematic view from an angle of the assembly structure of the fixed bracket 3 with the heat dissipation fan 32 and the condenser 31 in a refrigerator according to some embodiments of the present disclosure; FIG. 6 is a schematic view from an angle of the fixed bracket 3 in a refrigerator according to some embodiments of the present disclosure. The orientations of the views shown in FIG. 5 and FIG. 6 are the same. FIG. 7 is a schematic view from another angle of the assembly structure of the fixed bracket 3 with the heat dissipation fan 32 and the condenser 31 in a refrigerator according to some embodiments of the present disclosure; FIG. 8 is a schematic view from another angle of the fixed bracket 3 in a refrigerator according to some embodiments of the present disclosure; and the views shown in FIG. 7 and FIG. 8 have the same orientation. FIG. 9 is a structural exploded view of an assembly structure of a fixed bracket with a heat dissipation fan and a condenser in a refrigerator according to some embodiments of the present disclosure.

[0038] The fixed bracket 3 forms a pre-assembled integrated component with the heat dissipation fan 32, and forms an air duct structure for heat dissipation airflow to pass through, so that the airflow flows through the condenser 31 entirely, which improves the heat dissipation efficiency, makes the structure more compact and simplifies the assembly process.

[0039] The fixed bracket 3 is positioned in the middle of the transverse direction of the heat dissipation compartment 12, divides the heat dissipation compartment 12 into the first heat dissipation chamber 121 and the second heat dissipation chamber 122 along the transverse direction of the cabinet. The fixed bracket 3 is equipped with a fan fixing structure on one side facing the first heat dissipation chamber, and a condenser fixing structure on one side facing the second heat dissipation chamber. In other words, the fan fixing structure is oriented facing the compressor 2, while the condenser fixing structure is oriented facing the evaporating dish 4. The fixed bracket 3 is positioned along a front-rear direction.

[0040] The heat dissipation fan 32 is mounted on the fan fixing structure to induce the formation of a heat dissipation airflow that enters from outside of the cabinet, passes through the first heat dissipation chamber 121 and the second heat dissipation chamber 122, and then discharges from the cabinet. The condenser 31 is mounted on the condenser fixing structure and utilizes the heat dissipation airflow for cooling. The airflow passes sequentially through the compressor 2, the condenser 31, and the evaporating dish 4 to dissipate heat sequentially from the various components, which improves the heat dissipation efficiency.

[0041] The fixed bracket 3 is provided with a fan fixing structure and a condenser fixing structure on both sides respectively, for assembling the heat dissipation fan 32 and the condenser 31 to form a integrated air duct structure, so as to enable the heat dissipation fan 32 and the condenser 31 to occupy less space. The arrangement structure of the components in the heat dissipation compartment is more compact, providing a larger arrangement space for the compressor 2 as well as the evaporating dish 4, which is conducive to improving the heat dissipation efficiency. Compared with the prior art embodiments in which a condenser is provided above the evaporating dish 4, the structure of the present embodiments reduces the dimensions of the height direction of the heat dissipation compartment 12.

[0042] The fixed bracket 3 includes a bracket body 33 and a windshield 34. The bracket body 33 is in the shape of a square cylinder and extends in the transverse direction of the cabinet 1, i.e., along a left-right direction. The cylindrical shape of the bracket body is used to allow the heat dissipation airflow to pass through. The windshield 34 extends from a front end of the bracket body 33, and seals off the front regions of the first heat dissipation chamber 121 and the second heat dissipation chamber 122, thus preventing the dissipation airflow from recirculating, and only allowing airflow to be blown from the inside of the cylinder of the bracket body 33.

[0043] The fan fixing mechanism includes a plurality of fan fixing jaws 331 extending from the bracket body 33 toward the first heat dissipation chamber 121 to secure a casing of the heat dissipation fan 32, and a portion of the casing of the heat dissipation fan 32 is embedded in the bracket body.

[0044] The inner cylinder cross-section of one end of the bracket body 33 facing the first heat dissipation chamber 121 is adapted to match the outer shape of the casing of the heat dissipation fan 32 to avoid incorrect installation of the heat dissipation fan 32. That is, the bracket body 33 is designed to match the heat dissipation fan 32 by disposing matching structures such as convex ribs, grooves, or the like at a part of the bracket body 33 matching the heat dissipation fan 32. If the heat dissipation fan 32 is not assembled in the pre-designed direction, it will not fit due to structural interference, thus avoiding assembly errors. The above-mentioned fan matching structure confines the installation space for the heat dissipation fan 32 to a square cylindrical space. The heat dissipation fan 32 has an anti-misinsertion structure. The fan fixing jaws 331 secure the heat dissipation fan 32, and for disassembly, the heat dissipation fan 32 may be removed by toggling the fan fixing jaws 331, making both installation and disassembly extremely convenient.

[0045] The construction and positions of the fan fixing jaws 331 may be set based on the structure of the casing of the heat dissipation fan 32; for example, it may be positioned to protrude from a peripheral wall of the bracket body 33 toward the compressor 2. The heat dissipation fan 32 is assembled to the bracket body 33 via a snap-fit structure, facilitating disassembly and assembly while reducing the manufacturing process and improving assembly efficiency.

[0046] A vibration-damping foam (not shown in the figures) is placed between the casing of the heat dissipation fan 32 and the inner cylinder wall of the bracket body 33. The vibration-damping foam serves to reduce the vibrations generated during the rotation of the heat dissipation fan 32 and also enhances the sealing between the casing of the heat dissipation fan 32 and the bracket body 33. In a preferably embodiments, the heat dissipation fan 32 may be an axial flow fan, of which the axis extends along the left-right direction, and air blowing direction is from the first heat dissipation chamber 121 through the bracket body 33 to the second heat dissipation chamber 122.

[0047] The bracket body 33 is provided with one or more winding snaps 332 at an outer periphery of one side facing the first heat dissipation chamber 121 for wrapping the excessively long cable of the heat dissipation fan 32. The winding snaps protrude from the peripheral wall of the bracket body 33 for winding the cable. The cable of the heat dissipation fan 32 is too long, and if placed inside the heat dissipation compartment 12, it may result in disarray of components and a possible decrease in reliability during long-term use. The present embodiments solve the above cable arrangement problem by utilizing winding snaps. After the heat dissipation fan 32 is installed on the bracket body 33, the cable of the heat dissipation fan 32 is wrapped around the winding snaps 332 for one or several turns to avoid excessive length of the cable of the fan. Eventually, the cable is guided through the winding snaps 332 and a terminal is connected to a socket at the top of the heat dissipation compartment 12, thus preventing the cable of the heat dissipation fan 32 from being burned while soldering a piping of the condenser 31. The cable of fan is wound in a way that is quick and easy to use, and avoids the safety risks that might occur.

[0048] The condenser fixing structure includes a plurality of condenser fixing jaws 337 extending from the bracket body 33 facing the second heat dissipation chamber 122 to hold the condenser 31 using the condenser fixing jaws 337. In a preferable embodiment, the condenser 31 may include a microchannel condenser, thereby saving the space occupied by the condenser 31 and facilitating fitment with the bracket body 33. Gaps between the microchannels of the microchannel condenser are aligned with the direction of the heat dissipation airflow, and all the heat dissipation airflow needs to pass through the condenser 31, thereby enhancing the heat exchange efficiency.

[0049] The structure and position of the condenser fixing jaw 337 may be set according to the structure of the condenser 31. For example, the condenser fixing jaw 337 may extend from the upper and lower portions of the bracket body 33. At least a portion of the condenser 31 is embedded inside the bracket body 33 to facilitate airflow to pass through. In other words, the shape of the condenser 31 is designed to fit the inner cylinder of the bracket body 33 facing the second heat dissipation chamber 122, thereby improving the efficiency of the heat dissipation airflow passing through the condenser 31 and making the structure more compact. The condenser 31 is assembled with the bracket body 33 through a snap-fit structure, which facilitates disassembly and assembly, reduces the process, and improves the assembly efficiency. The condenser 31 is integrally embedded in the bracket body 33 and located inside the air duct, making full use of the heat dissipation airflow and also avoiding occupying the space of the evaporating dish 4.

[0050] During assembly, the condenser 31, the heat dissipation fan 32, and the fixed bracket 3 may be pre-assembled to form a pre-assembled integrated component, and then installed as a whole inside the cabinet 1.

[0051] The fixed bracket 3 may also be provided with an installation snap 334 and a fixation screw post 335. The installation snap 334 is located at the bottom of the fixed bracket 3 for snapping to the bottom plate of the heat dissipation compartment 12. The fixation screw post 335 is located at a rear portion of the fixed bracket 3 for fixing with a rear wall panel of the heat dissipation compartment 12 using the screws. The installation snaps 334 and the fixation screw posts 335 enable the fixed bracket 3 to be reliably assembled with the cabinet 1, and he disassembly and assembly process is simple, reducing the disassembly and assembly process.

[0052] The top portion of the fixed bracket 3 is also provided with a guide groove 336 for making the refrigeration line pass through, wherein the refrigeration line connects the compressor 2 and the condenser 31. The fixed bracket 3 may also be provided with a ribbed groove structure for lines and pipes connecting the first heat dissipation chamber 121 and the second heat dissipation chamber 122 to pass through, as needed.

[0053] A grille member may be disposed in the inside of the cylinder of the bracket body 33, which creates a space between the heat dissipation fan 32 and the condenser 31.

[0054] Based on the foregoing description, the person skilled in the art is able to understand that by arranging the compressor 2, the fixed bracket 3, and the evaporating dish 4 sequentially in the heat dissipation compartment 12 along the left-right direction of the cabinet 1, as compared to the prior art where a condenser is arranged inside a evaporating dish, the height of the heat dissipation compartment 12 is effectively reduced, which in turn frees up more space for the storage compartment 11 of the refrigerator, thereby making the storage compartment 11 have a larger storage space.

[0055] Further, by mounting the condenser 31 and the heat dissipation fan 32 on the fixed bracket 3, and assembling the heat dissipation fan 32 and the condenser 31 respectively with the bracket body 33 which is in the shape of a square cylinder at both sides through the snap-in structure, the air flowing into the heat dissipation compartment 12 all flow through the condenser 31 and cool the condenser 31, ensuring the cooling effect of the condenser 31.

[0056] To this point, the technical solution of the present disclosure has been described in conjunction with a plurality of previous embodiments, but it is readily understood by those skilled in the art that the scope of protection of the present disclosure is not limited to these specific embodiments. Without deviating from the technical principles of the present disclosure, the person skilled in the art may split and combine the technical solutions in each of the foregoing embodiments, or make equivalent alterations or replacements to the relevant technical features. Any changes, equivalent substitutions, improvements, etc. made within the technical concept and/or technical principles of the present disclosure fall within the scope of protection of the present disclosure.
