Description
TECHNICAL FIELD

Present application belongs to the technical field of refrigeration equipment, specifically providing a refrigerator with reserved installation space arranged in the bottom heat dissipation compartment.


BACKGROUND

In the existing technology, some refrigerators, especially built-in refrigerators, arrange the condenser, compressor, and evaporating tray within a heat dissipation compartment at the bottom of the cabinet. A heat dissipating fan draws ambient air from outside the refrigerator and facilitates air circulation within the heat dissipation compartment for convective cooling of the condenser and compressor.


Since refrigerator products are marketed in series, each series may be divided into several models ranging from high to low end, with most of main functional components being common across different models. However, there might be differences in functional configurations among some mid to high-end models. By differentiating functions, the competitiveness and selling points of refrigerator products are enhanced.


To maintain a cost advantage while maximizing product competitiveness, refrigerators in the aforementioned series typically reserve space and environment interfaces for high-end models that may be used in the basic model. This allows for the addition of auxiliary functional components without the need for significant changes to the overall product model.


Some auxiliary functional components need to be placed outside the insulation layer, where the heat dissipation compartment of the compressor (also known as a compressor compartment or a compressor chamber) is a commonly used location. However, due to the numerous components already present in the heat dissipation compartment, it presents a significant technical challenge to arrange the required installation space without affecting heat radiating efficiency.

As shown in FIGS. 1 to 3, in some embodiments of present application, a refrigerator mainly includes a cabinet 1, a compressor 2, a duct assembly 3, an evaporating tray 4, and an evaporator 5.


Referring again to FIGS. 1 to 3, the cabinet 1 defines storage chambers 11, a heat dissipation compartment 12, and a refrigeration chamber 13. The storage chambers 11 are not limited to the two shown in FIGS. 1 and 2 but can be configured in other quantities as needed, such as one or more. When there is one storage chamber 11, it can be a freezer, a variable temperature chamber, or a refrigerated chamber. When there are two or more storage chambers 11, the multiple storage chambers 11 include at least one or more of a freezer, a variable temperature chamber, and a refrigerated chamber. In the specific implementation of the technical scheme of this application, a person skilled in the art can configure the number and functions of storage chambers 11 as needed.


Continuing to refer to FIGS. 1 to 3, the cabinet 1 has a heat dissipation compartment 12 at its rear bottom. In some embodiments, a bottom of the storage chamber 11 forms a refrigeration chamber 13 for arranging the evaporator 5. That is, the refrigeration chamber 13 can be set above a front of the heat dissipation compartment 12, thereby achieving a bottom-placed evaporator refrigerator. The refrigeration chamber 13 occupies a bottom area of an inner liner, elevating the storage chamber 11 and reducing a degree of bending for users when placing or retrieving items, thus enhancing the user experience. The evaporator 5 is installed inside the refrigeration chamber 13, providing cooling to the interior of the storage chamber 11.


The heat dissipation compartment 12 is divided by the duct assembly 3 into a first heat dissipation chamber 121 and a second heat dissipation chamber 122, partitioning the space and arranging different components respectively. A right side of the second heat dissipation chamber 122 reserves an installation space 123.



FIG. 4 is a schematic diagram showing the main component distribution inside the heat dissipation compartment 12 of the refrigerator according to some embodiments of present application. FIG. 5 is a structural exploded view of the duct assembly 3 with a heat dissipating fan 32 and a condenser 31 in the refrigerator according to some embodiments of present application; from left to right along the horizontal direction of the refrigerator, the compressor 2, the duct assembly 3, and the evaporating tray 4 are sequentially arranged inside the heat dissipation compartment 12. That is, the compressor 2, the duct assembly 3, and the evaporating tray 4 are sequentially set within the heat dissipation compartment 12 along a horizontal direction of the cabinet 1.


The duct assembly 3 is positioned in a middle of the heat dissipation compartment 12, dividing it along the horizontal direction of the cabinet 1 into the first heat dissipation chamber 121 and the second heat dissipation chamber 122. The compressor 2 and the evaporating tray 4 are respectively placed within the first heat dissipation chamber 121 and the second heat dissipation chamber 122. A condenser 31 is installed on a side facing the evaporating tray 4 of the duct assembly 3, and a heat dissipating fan 32 is installed on a side facing the compressor 2 of the duct assembly 3. Thus, the duct assembly 3, along with the heat dissipating fan 32 and condenser 31, form a pre-assembled unit creating a duct structure through which the heat dissipating air flows, ensuring all air passes through the condenser 31. This enhances heat dissipating efficiency while making the structure more compact and simplifying the assembly process.


A fan fixing structure is provided on a side facing the first heat dissipation chamber 121 of the duct assembly 3, and a condenser fixing structure is provided on a side facing the second heat dissipation chamber 122 of the duct assembly 3. The heat dissipating fan 32 is mounted on the fan fixing structure to facilitate the formation of a heat dissipating airflow that enters from outside the cabinet 1, passes through the first and second heat dissipation chambers 121 and 122, and then exits the cabinet 1. The condenser 31 is mounted on the condenser fixing structure and is cooled by the heat dissipating airflow. The airflow sequentially cools the compressor 2, condenser 31, and evaporating tray 4, thereby improving heat dissipating efficiency.


The duct assembly 3 includes a bracket body 33 and a wind deflector 34. The bracket body 33 is square cylindrical in shape and extends along the horizontal direction of the cabinet 1, that is, extends in a left-right direction. The cylindrical shape of the bracket body 33 allows the heat dissipating airflow to pass through. The wind deflector 34 extends from a front end of the bracket body 33 to block a front area of the first and second heat dissipation chambers 121 and 122, thus preventing the heat dissipating airflow from recirculating and allowing the heat dissipating airflow to blow only through the cylinder of the bracket body 33.


The fan fixing structure and the condenser fixing structure can be claw structures, respectively connecting to the heat dissipating fan 32 and the condenser 31, embedding part of the heat dissipating fan 32 and condenser 31 inside the duct assembly 3, which makes the structure more compact. The bracket body 33, being square cylindrical in shape, is assembled on both sides with the heat dissipating fan 32 and condenser 31 through snap-fit structures, ensuring that air flowing into the heat dissipation compartment 12 passes through the condenser 31, cooling it and ensuring the cooling effect of the condenser 31. This structural optimization also provides possibilities for arranging the installation space 123.


The heat dissipating fan 32 preferably uses an axial fan, with an axis extending in the left-right direction, and an airflow direction blowing from the first heat dissipation chamber 121 through the bracket body 33 towards the second heat dissipation chamber 122. The condenser 31 can preferably use a microchannel condenser to save space occupied by the condenser 31, facilitating cooperation with the bracket body 33. The gaps between microchannels of the microchannel condenser align with a direction of the heat dissipating airflow, requiring all the heat dissipating airflow to pass through the condenser 31, thereby improving the heat exchange efficiency.


The duct assembly 3 enhances the heat exchange efficiency of the heat dissipating airflow with the condenser 31, achieving space-saving while satisfying heat dissipating efficiency.


The evaporating tray 4 is installed inside the second heat dissipation chamber 122 to catch water discharged from a drainage tube 41 connected to the refrigeration chamber 13. The drainage tube 41 extends from the refrigeration chamber 13 to the heat dissipation compartment 12, that is, an upper end of the drainage tube 41 is connected to a bottom of the refrigeration chamber 13, and a lower end extends to the evaporating tray 4. The drainage tube 41 is used to discharge defrost water of the refrigerator into the evaporating tray 4, where the water is evaporated into the ambient air.


A bottom plate of the heat dissipation compartment 12 is equipped with a heat dissipating air inlet 321 and a heat dissipating air outlet 322 at a front of the first and second heat dissipation chambers 121 and 122, respectively. The environmental air below the refrigerator enters the heat dissipation compartment 12 through the heat dissipating air inlet 321, first exchanges heat with the compressor 2, then passes through the heat dissipating fan 32 and condenser 31, accelerating the evaporation of water inside the evaporating tray 4, and finally is expelled under the refrigerator through the heat dissipating air outlet 322. The smooth flow of the heat dissipating air improves the heat dissipating efficiency of each component. An isolation piece can further be added on the underside of the refrigerator's bottom plate to separate the heat dissipating air inlet 321 and the heat dissipating air outlet 322, preventing the expelled heat dissipating air from being re-intaken.


The bottom plate of the heat dissipation compartment 12 can also be referred to as a compressor support plate, on whose left and right sides a first roller 51 and a second roller 52 are respectively set. That is, the first roller 51 is set on the bottom plate of the heat dissipation compartment 12 on one side opposite the compressor 2 relative to the duct assembly 3; the second roller 52 is set on the bottom plate of the heat dissipation compartment 12 on one side opposite the evaporating tray 4 relative to the duct assembly 3. The first roller 51 and the second roller 52 facilitate rolling when moving the refrigerator 1. The space above the second roller 52 is designated as the installation space 123, and a relationship between an auxiliary functional component installed within the installation space 123 and the second roller 52 needs optimization to avoid structural interference and impacts during transportation.


Installation space 123 may be equipped with one or more mating structures, each of which is used to install an auxiliary functional component. A length of installation space 123 along the horizontal direction of the refrigerator (i.e., left-right direction) is greater than or equal to 10% of a length of the heat dissipation compartment 12 along the horizontal direction of the refrigerator, ensuring sufficient space for arranging auxiliary functional components.


The mating structures may include a first mating structure set on a bottom plate of installation space 123 and a second mating structure set on a sidewall of installation space 123 opposite the duct assembly 3 (i.e., a right sidewall). The first and second mating structures are used for arranging different auxiliary functional components, and can choose the corresponding auxiliary functional component according to the refrigerator's specification. The first mating structure can surround the second roller 52.



FIG. 6 is a schematic diagram of a refrigerator according to some embodiments of present application, showing a vacuum pump 61 installed in the installation space 123 using the first mating structure; FIG. 7 is a schematic diagram of the structure shown in FIG. 6 from another angle; FIG. 8 is a schematic cross-sectional view taken along line A-A in FIG. 7. FIG. 9 is a schematic diagram showing the position of the second roller 52 and fixing holes 613 in a refrigerator according to some embodiments of present application.


The first mating structure may include multiple fixing holes 613 and fixing columns 612 set correspondingly one-to-one with the multiple fixing holes 613; and an auxiliary functional component mounted on the first mating structure can be a vacuum pump 61. The vacuum pump 61 is mounted on the fixing columns 612. In some embodiments, the fixing holes 613 can be riveting holes, and bottom ends of the fixing columns 612 are riveted to the fixing holes 613. The vacuum pump 61 is fixed to top of the fixing columns 612 through connecting parts, such as screws, keeping the vacuum pump 61 at a distance from the bottom plate.


Heights of the fixing columns 612 are configured so that a first height from a bottom of the second roller 52 to the bottom plate of the heat dissipation compartment 12 is less than a second height from a top of the second roller 52 to a bottom of the vacuum pump 61. Such a configuration prevents the second roller 52 from hitting the vacuum pump 61 in case of drops during transportation of the refrigerator, potentially preventing a damage of the vacuum pump 61. Even in case of bumps, the second roller 52 can at most be level with the bottom plate, ensuring that there is still some clearance between the vacuum pump 61 and the second roller 52. For example, as shown in FIG. 8, the first height can be 9.3 mm, and the second height can be 11 mm, meaning the distance from the bottom plate of the heat dissipation compartment 12 to the second roller 52 is 9.3 mm, and the distance from the vacuum pump 61 to the second roller 52 is 11 mm. These specific dimension values are just examples, and those skilled in the art can flexibly configure them based on component sizes, refrigerator specifications, etc., such as adjusting proportionally or within a certain range. The specific numeric values mentioned in the description of this embodiment are also examples.


A top of the vacuum pump 61 is spaced at a gap from a top wall of the installation space 123, which can be about 20 mm, and a front wall 14 of the installation space 123 opposite to a front end of the vacuum pump 61 forms a clearance greater than a preset value by pressing, with the preset value being set to 5 mm. The front wall 14 of the installation space 123 (also referred to as the bottom steel plate, forming a bottom of an insulation layer) is inclined to reserve space for the refrigeration chamber 13, which might interfere with the front end of the vacuum pump 61. Therefore, the clearance created by pressing is necessary to buffer and prevent the bottom steel plate 14 from damaging the vacuum pump 61 during falls. The bottom steel plate 14 is generally a sheet metal part, and its pressing for clearance is easy to achieve.


Taking a cabinet with a horizontal width of the bottom plate of heat dissipation compartment 12 being 820 mm as an example, a specific dimension of the installation space is introduced. A horizontal distance between the evaporating tray 4 and the sidewall (right sidewall) of the installation space 123 is only 88 mm, while an own horizontal length of the vacuum pump 61 is 70 mm. A horizontal position of the vacuum pump 61 can be set such that a left side is 8 mm away from the evaporating tray, and a right side is 10 mm away from the right sidewall. Correspondingly, a proportion of the horizontal length of the vacuum pump 61 occupies 79.5% of a total horizontal size of the installation space 123, the distance from the left side of the vacuum pump 61 to the evaporating tray 4 occupies 9.1% of the total horizontal size of the installation space 123, and the distance from the right side of the vacuum pump 61 to the right sidewall occupies 11.4% of the total horizontal size of the installation space 123. That is, a horizontal distance from the evaporating tray 4 to the sidewall of the vacuum pump 61 can be less than a distance from the vacuum pump 61 to the sidewall (right sidewall) of the installation space 123.


The above structural dimensions are the result of extensive calculations, trials, and breakthroughs in the mentioned spatial constraints, after improvements in component layout and verification of matching mechanisms, making it almost the only feasible layout method. Those skilled in the art can flexibly configure specific dimensions based on component sizes, refrigerator specifications, etc., such as adjusting proportionally or within a certain range.


The mentioned vacuum pump 61 can be used for evacuating the storage chamber 11, for example, in combination with a gas modulation module to adjust the atmospheric environment inside.



FIG. 10 is a schematic diagram according to some embodiments of present application showing an ice water valve 62 installed in the installation space 123 using the second mating structure; FIG. 11 is a schematic diagram of the structure shown in FIG. 10 from another angle; FIG. 12 is a schematic cross-sectional view taken along line B-B in FIG. 11.


The second mating structure includes positioning slots and fixing holes located on the sidewall of the installation space, which are not visible in the diagram due to being obscured by the right sidewall. An auxiliary functional component installed on the second mating structure can be an ice water valve 62. The ice water valve 62 is connected to the second mating structure through a fixed frame 623.


The fixed frame 623 is configured to position the ice water valve 62 in a center of the installation space 123, maintaining specified distances from the sidewall, top wall, bottom wall of the installation space, and the evaporating tray. For example, a horizontal length of the ice water valve 62 is 49 mm, for a cabinet with the horizontal width of the bottom plate of the heat dissipation compartment 12 being 820 mm, the horizontal length of the ice water valve occupies 55.7% of the total horizontal size of the installation space 123.


In terms of height, a height of the ice water valve 62 is 89 mm, and a total height of the installation space 123 is 165 mm, so that a proportion of the height of the ice water valve 62 is 53.9% of the total height of the installation space. Those skilled in the art can flexibly configure the specific dimensions based on component sizes, refrigerator specifications, etc., such as adjusting proportionally or within a certain range.


The fixed frame 623 extends from the right sidewall toward the installation space 123, creating a gap between the ice water valve 62 and the right sidewall, and the fixed frame 623 can be attached to the cabinet 1 through screws and positioning posts in coordination with the fixing holes and the positioning slots.


The ice water valve 62 can be used to control a water flow of an ice maker inside the refrigerator.


The ice water valve 62 and the vacuum pump 61 can be optionally installed to provide differentiated auxiliary functions, meeting different customers' needs.


The specific dimensions mentioned are results of layout for a refrigerator with the horizontal width of the bottom plate of the heat dissipation compartment 12 being 820 mm. In practice, a person skilled in the art can proportionally adjust the layout based on the technical concept of these embodiments and the size requirements.


From the description above, a person skilled in the art can understand that the heat dissipation compartment 12 reserves the installation space 123 on the side far from the duct assembly 3 relative to the evaporating tray 4, equipped with one or more mating structures for installing auxiliary functional components. By optimizing the device layout within the confined space of the heat dissipation compartment 12, it achieves the purpose of reserving installation space. This provides installation space for extending functionalities of different refrigerator models, enhancing product competitiveness and saving development costs.


Thus, the technical solutions of present application have been described through several embodiments, but it is understood by a person skilled in the art that the scope of protection of present application is not limited to these specific embodiments. Without departing from the principles of present application, a person skilled in the art can split and combine these technical solutions or make equivalent changes or substitutions to the related technical features. Any changes, equivalent replacements, or improvements made within the conceptual framework and/or principles of present application fall within the scope of protection of present application.
