Description

Technical Field

[0001] This utility model relates to the field of household appliances, and in particular to a refrigeration device. Background Technology

[0002] In recent years, the trend of pursuing efficient space utilization in home furnishings has become increasingly prominent, and more and more consumers prefer ultra-thin models when purchasing refrigerators. Single-system refrigerators use a single circulation loop for the refrigerant to complete the cooling tasks of the refrigerator and freezer compartments, which helps to control the overall space occupied by the refrigerator.

[0003] In related technologies, the back-mounted air duct refrigeration system commonly used in single-system refrigerators requires a considerable amount of space to be reserved at the back of the refrigerator for air duct layout and heat dissipation due to its structural characteristics. This inevitably encroaches on the overall depth of the refrigerator body, resulting in low utilization of the internal depth space. Utility Model Content

The third side of the equipment mounting cavity is connected to the refrigerator chamber via the return air channel and the refrigeration return air outlet in sequence.

[0016] According to the refrigeration equipment provided by this utility model, a plurality of refrigeration air outlets are provided on the first air supply channel, each of the refrigeration air outlets is located on the inner side wall of the refrigeration chamber, and the plurality of refrigeration air outlets are evenly spaced along the height direction of the refrigeration chamber.

[0017] According to the refrigeration equipment provided by this utility model, a process window is provided on the inner side plate, and a sealing cover is detachably connected to the process window.

[0018] According to the refrigeration equipment provided by this utility model, the refrigerated air duct assembly includes: a main molded part;

[0049] In existing technology, the overall air duct structure of a refrigerator is usually arranged on the back side wall in the depth direction of the refrigerator. This method makes the refrigerator thicker for the same volume and occupies a lot of space in the thickness direction.

[0050] To address the aforementioned problems, this application proposes a refrigeration device, such as... Figures 1 to 6 As shown, a refrigerator is used as an example, but it should be understood that the refrigeration equipment of this application can also be used as a freezer or any other suitable equipment.

[0051] In one embodiment of this application, such as Figures 1 to 6 As shown, the refrigeration equipment includes: a cabinet 1, a refrigerated air duct assembly 2, a frozen air duct assembly 3, and a refrigeration circulation assembly 4. The cabinet 1 has a freezer compartment 11 and a refrigerator compartment 12, with the refrigerator compartment 12 typically located at the top of the freezer compartment 11. The refrigerated air duct assembly 2 is mounted on the inner side wall of the back of the refrigerator compartment 12, and has a refrigerated air outlet 21 located within the refrigerator compartment 12. The refrigerated air outlet 21 communicates with the refrigerated air duct assembly 2 and extends along the width of the refrigerator compartment 12, allowing the cold air blown from the refrigerated air outlet 21 to cover as much of the area within the refrigerator compartment 12 as possible, resulting in a more uniform temperature within the refrigerator compartment 12 and improved refrigeration efficiency. The refrigeration air duct assembly 3 is connected to the refrigeration air duct assembly 2 and is located on the inner side wall of the freezer compartment 11 in the depth direction (e.g., the left or right side of the freezer compartment 11). It has a refrigeration air supply port 31, a refrigeration air return port 32 and a refrigeration air return port 33 connected to the refrigeration air duct assembly 3. The refrigeration air supply port 31 is located in the freezer compartment 11, the refrigeration air return port 32 is located in the freezer compartment 11, and the refrigeration air return port 33 extends to the refrigeration compartment 12. The refrigeration circulation assembly 4 is located in the refrigeration air duct assembly 3 and is used to cool the air introduced by the refrigeration air return port 32 and the refrigeration air return port 33 and then blow it out by the refrigeration air supply port 21 and the refrigeration air supply port 31.

[0052] Specifically, such as Figure 1As shown, the cabinet 1 includes an inner liner structure, which forms a refrigerator compartment 12 and a freezer compartment 11. The two compartments are arranged vertically, similar to those in a conventional refrigerator. That is, the refrigerator compartment 12 is located above the freezer compartment 11. Multiple partitions are provided within the freezer compartment 11 and the refrigerator compartment 12 to divide the space into multiple layers for storing food.

[0053] During operation, the refrigeration cycle component 4 is activated, and the refrigeration return air inlet 32 ​​and the refrigerator return air inlet 33 in the refrigeration air duct component 3 begin to function. The refrigeration return air inlet 32 ​​draws return air from the freezer compartment 11, while the refrigerator return air inlet 33 extends to the refrigerator compartment 12 and draws return air from the refrigerator compartment 12.

[0054] The return air drawn from the freezer compartment 11 and the refrigerator compartment 12 is introduced into the refrigeration air duct assembly 3. Here, the refrigeration cycle assembly 4 centrally cools this mixed air. The refrigeration cycle assembly 4 utilizes the principle of heat absorption through refrigerant evaporation to lower the temperature of the mixed air, thereby achieving effective cooling of the air.

[0055] After cooling, the air is divided into two parts. One part is blown into the refrigerator compartment 12 through the refrigerator air outlet 21 of the refrigerator air duct assembly 2 to provide a continuous low temperature environment for the food in the refrigerator compartment 12 and ensure its freshness; the other part is blown into the freezer compartment 11 through the freezer air outlet 31 of the freezer air duct assembly 3 to maintain the low temperature freezing state in the freezer compartment 11 and keep the frozen food stable.

[0056] Inside the refrigerator compartment 12 and the freezer compartment 11, the cooled air exchanges heat with the existing air, absorbing heat released by the food and heat seeping in from the outside, and gradually warms up. Then, this warmed air is drawn back into the freezer return air vent 32 and the refrigerator return air vent 33 and re-enters the freezer air duct assembly 3 for cooling. This cycle repeats continuously, achieving dynamic balance and stable control of the refrigerator's internal temperature.

[0057] This application places the refrigeration air duct assembly 2 on the inner side wall of the back of the refrigerator compartment 12, and the freezing air duct assembly 3 on the inner side wall of the freezer compartment 11 in the depth direction. Since the refrigeration circulation assembly 4 is not placed inside the refrigerator compartment 12, but rather placed in the freezing air duct assembly 3, space occupation in the depth direction is avoided, effectively improving the space utilization of the refrigerator in the depth direction and making the overall thickness of the refrigerator thinner. This refrigeration device can simultaneously draw return air from both the freezer compartment 11 and the refrigerator compartment 12, perform a concentrated cooling process in the freezing air duct assembly 3, and then blow it back to their respective compartments through the refrigeration air outlet 21 and the freezing air outlet 31, respectively. This avoids the complexity and space occupation of having a separate evaporator 42 in the refrigerator compartment 12, simplifies the single-system structure, and greatly reduces or even eliminates the space occupied at the back of the refrigerator.

[0058] Since the refrigeration air duct assembly 2 is located on the inner wall at the back of the refrigeration compartment 12, and the freezer air duct assembly 3 is located on the inner wall in the depth direction of the freezer compartment 11, the two are connected. Figures 1 to 6 As shown, the refrigeration equipment also includes: a pre-embedded air duct 5, which is set between the freezer compartment 11 and the refrigerator compartment 12. One end of the pre-embedded air duct 5 extends to connect with the refrigerator air duct assembly 2, and the other end of the pre-embedded air duct 5 extends to connect with the freezer air duct assembly 3.

[0059] Specifically, one end of the pre-embedded air duct 5 is connected to the refrigerated air duct assembly 2, allowing air from the refrigerated air duct assembly 2 to enter the refrigerated air duct assembly 3 through the pre-embedded air duct 5. The other end of the pre-embedded air duct 5 is connected to the refrigerated air duct assembly 3, allowing air from the refrigerated air duct assembly 3 to enter the refrigerated air duct assembly 2 through the pre-embedded air duct 5. In this way, the pre-embedded air duct 5 serves to connect the refrigerated air duct assembly 2 and the refrigerated air duct assembly 3, enabling air circulation between the two air duct assemblies.

[0060] With the installation of pre-embedded air ducts 5, the air in the refrigerator compartment 12 and the freezer compartment 11 can be circulated and cooled under the action of the refrigeration cycle assembly 4. The refrigeration cycle assembly 4 cools the air introduced from the freezer return air inlet 32 ​​and the refrigerator return air inlet 33 of the freezer air duct assembly 3, and then blows it out through the refrigerator air outlet 21 and the freezer air outlet 31. Among them, a part of the cooled air enters the refrigerator air duct assembly 2 through the pre-embedded air duct 5, and then is blown into the refrigerator compartment 12 through the refrigerator air outlet 21; the other part of the cooled air is blown directly into the freezer compartment 11 through the freezer air outlet 31. At the same time, some of the air in the refrigerator compartment 12 enters the freezer air duct assembly 3 through the refrigerator return air outlet 33 and the pre-embedded air duct 5, and is cooled together with the air in the freezer compartment 11 in the freezer air duct assembly 3, forming a complete cycle.

[0061] Based on the above embodiments, in some embodiments, such as Figures 1 to 6As shown, the refrigeration air duct assembly 3 forms a first air supply duct 34, an equipment installation cavity 35, and a return air duct 36. The refrigeration air duct assembly 2 and the inner wall of the refrigeration chamber 12 together form a second air supply duct 22. The refrigeration circulation assembly 4 is disposed in the equipment installation cavity 35. The first side of the equipment installation cavity 35 is connected to the refrigeration chamber 11 in sequence through the first air supply duct 34 and the refrigeration air supply outlet 31. The second side of the equipment installation cavity 35 is connected to the refrigeration chamber 12 in sequence through the pre-embedded air duct 5, the second air supply duct 22, and the refrigeration air supply outlet 21. The third side of the equipment installation cavity 35 is connected to the refrigeration chamber 11 in sequence through the return air duct 36 and the refrigeration return air outlet 32. The third side of the equipment installation cavity 35 is connected to the refrigeration chamber 12 in sequence through the return air duct 36 and the refrigeration return air outlet 33.

[0062] In this embodiment, during operation, air from the freezer chamber 11 is introduced into the return air duct 36 through the freezer return air inlet 32. The return air duct 36 is connected to the equipment mounting cavity 35, and the air enters the refrigeration cycle assembly 4 within the equipment mounting cavity 35. The refrigeration cycle assembly 4 cools the air, lowering its temperature by utilizing the heat absorption principle of refrigerant evaporation. The cooled air is then blown out through the first air supply duct 34 and the freezer air outlet 31, returning to the freezer chamber 11 to maintain the low-temperature environment of the freezer chamber 11.

[0063] Meanwhile, air from the cold storage compartment is introduced into the return air duct 36 through the cold storage return air vent 33. The return air duct 36 is connected to the equipment mounting cavity 35, and the air enters the refrigeration cycle assembly 4 within the equipment mounting cavity 35. The refrigeration cycle assembly 4 cools the air, lowering its temperature by utilizing the heat absorption principle of refrigerant evaporation. The cooled air then enters the second air supply duct 22 through a pre-embedded pipe, and is blown out through the cold storage air supply vent 21, maintaining the low-temperature environment of the cold storage compartment 12.

[0064] In some embodiments, such as Figures 4 to 6 As shown, the refrigeration duct assembly 3 includes: a main frame 37, an inner side plate 38, and a side plate 39; the inner side plate 38 is fixedly disposed on one side of the main frame 37 and together with the main frame 37 forms an equipment mounting cavity 35 and a return air duct 36; the side plate 39 is fixedly disposed on one side edge of the main frame 37, and the side plate 39 and the main frame 37 together form a first air supply duct 34.

[0065] In this embodiment, the freezing air duct assembly 3 is located on the inner wall of the freezing chamber 11 and can guide and circulate cold air. The inner side plate 38 allows the solid frame structure inside the main frame 37 to enclose different functional spaces. For example, the constructed equipment mounting cavity 35 is used for the installation of the refrigeration cycle assembly 4, and the constructed return air duct 36 can effectively collect and guide air from the freezing chamber 11, allowing it to smoothly enter the refrigeration cycle assembly 4 for cooling. The first air supply duct 34, enclosed by the side plate 39, can transport the cooled air back to the freezing chamber 11, achieving refrigeration circulation within the freezing chamber 11, maintaining the low-temperature environment within the freezing chamber 11, and ensuring the freshness and quality of frozen food.

[0066] Specifically, the inner side panel 38 is disposed on the inner side surface of the main frame 37, and the outer side surface of the main frame 37 is connected to the left wall of the freezer compartment 11. An enclosure structure is integrally formed on the main frame 37, located in the middle of the main frame 37 and occupying most of the space of the main frame 37. After the inner side panel 38 is connected to the main frame 37, the space formed by the enclosure serves as the equipment mounting cavity 35 of the refrigeration cycle assembly 4. A return air duct 36 is formed at the bottom of the enclosure. The return air in the freezer compartment 11 and the refrigerator compartment 12 flows back through the return air duct 36 and is recooled under the action of the refrigeration cycle assembly 4.

[0067] Understandably, the integral molding of the main frame 37 and the fixed connection of the inner side plate 38 and the side plate 39 facilitate the overall installation and connection. Furthermore, this method integrates the equipment mounting cavity 35, the return air duct 36, and the first air supply duct 34, resulting in a more compact overall structure and better space utilization.

[0068] In some embodiments, such as Figures 4 to 6 As shown, a plurality of refrigeration air outlets 31 are provided on the first air supply channel 34. Each refrigeration air outlet 31 is located on the inner side wall of the refrigeration chamber 11, and the plurality of refrigeration air outlets 31 are evenly spaced along the height direction of the refrigeration chamber 11.

[0069] Specifically, in this embodiment, the refrigeration air outlets 31 are evenly spaced along the height of the freezer compartment 11 to ensure that cold air is evenly distributed at all height levels within the freezer compartment 11. This arrangement avoids cold air concentrating in a certain area, thereby improving the temperature uniformity within the freezer compartment 11. Each refrigeration air outlet 31 is connected to the first air supply channel 34, ensuring that cooled air can enter the freezer compartment 11 evenly.

[0070] The shape and size of the freezer air vents 31 can be optimized according to the actual needs of the freezer compartment 11 to achieve the best airflow effect. The arrangement of the freezer air vents 31 can also be adjusted according to the size and shape of the freezer compartment 11 to adapt to different refrigerator models and designs. For example, when the freezing demand is low, the number and size of the freezer air vents 31 can be reduced. Conversely, when the freezing demand is high, the number and size of the freezer air vents 31 can be increased.

[0071] This embodiment achieves uniform distribution of cold air by evenly arranging multiple refrigeration air outlets 31 along the height direction on the inner side wall of the freezer chamber 11, thereby improving refrigeration efficiency and temperature uniformity, while maintaining structural compactness and a good user experience.

[0072] In some embodiments, such as Figure 4 and Figure 5 As shown, the refrigerated air duct assembly 2 includes: a main body molding part 23 and an inner connecting plate 24; the inner connecting plate 24 is connected to the main body molding part 23 and is located inside the refrigerated chamber 12. A channel groove is formed on the main body molding part 23, and the channel groove and the inner side wall of the refrigerated chamber 12 enclose the second air supply channel 22.

[0073] Specifically, one end of the second air intake duct is equipped with a damper assembly 6, which controls the opening and closing of the second air intake duct and also controls the air intake volume. The other end of the second air intake duct is connected to the refrigerator compartment 12, thereby enabling control of the entry of cold air. The damper assembly 6 adopts a mature damper assembly structure, therefore, the specific structure of the damper assembly 6 is not limited here.

[0074] Understandably, this method enables the main molding component 23 to fit with the side wall of the refrigerator compartment 12, thereby forming a second air intake channel. The second air intake channel enables the delivery of cold air, and the fit with the side wall of the refrigerator compartment 12 makes the overall structure more compact, allowing for higher utilization of the internal space.

[0075] In some embodiments, such as Figures 1 to 5 As shown, at least one refrigerated air outlet 21 is provided at the extended end of the second air supply duct 22. The refrigerated air outlet 21 is arranged in the upper region of the refrigerator compartment 12, usually on the top or inner wall near the top of the refrigerator compartment 12. By supplying air to the upper region, the natural sinking property of cold air is utilized to ensure that cold air can evenly cover the entire refrigerator compartment 12, thereby improving temperature uniformity.

[0076] As needed, multiple refrigerated air outlets 21 can be set, and the multiple refrigerated air outlets 21 can be set sequentially along the height direction of the refrigeration equipment. Due to the natural sinking characteristic of cold air, the air outlets at higher positions have a larger flow area and can release more cold air. Therefore, the flow area of ​​the refrigerated air outlets 21 located at higher positions needs to be greater than that of the refrigerated air outlets 21 located at lower positions to ensure that the cold air can effectively cover the upper area of ​​the refrigeration compartment 12. At the same time, the flow area of ​​the air outlets at lower positions is smaller, which can accurately control the flow of cold air and avoid excessive concentration of cold air at lower positions.

[0077] In this embodiment, multiple refrigeration air outlets 21 are sequentially arranged along the height direction in the upper region of the refrigeration chamber 12, and the flow area of ​​the air outlets at higher locations is greater than that at lower locations. This allows the refrigeration equipment to achieve a more uniform temperature distribution and a more efficient refrigeration effect.

[0078] In some embodiments, such as Figures 1 to 6 As shown, the refrigeration cycle assembly 4 includes a fan 41 and an evaporator 42. Both the fan 41 and the evaporator 42 are disposed in the equipment mounting cavity 35. The fan 41 has an air inlet side and an air outlet side. The evaporator 42 is configured to cool the air flowing through it. The air outlet side of the fan 41 is connected to the first air supply channel 34 and the pre-embedded air duct 5, and is used to send the air cooled by the evaporator 42 into the freezer compartment 11 and the refrigerator compartment 12 respectively. The air inlet side of the fan 41 is connected to the return air channel 36, and is used to guide the return air that converges through the freezer return air port 32 and the refrigerator return air port 33 to flow through the evaporator 42.

[0079] Specifically, the outlet side of the fan 41 is connected to the first air supply duct 34 and the pre-embedded air duct 5, used to deliver the air cooled by the evaporator 42 into the freezer compartment 11 and the refrigerator compartment 12 respectively. The cooled air enters the freezer compartment 11 through the first air supply duct 34 and the freezer air outlet 31 to maintain the low temperature environment in the freezer compartment 11; at the same time, the cooled air also enters the refrigerator compartment 12 through the pre-embedded air duct 5, the second air supply duct 22 and the refrigerator air outlet 21 to provide a continuous low temperature environment for the refrigerator compartment 12. The inlet side of the fan 41 is connected to the return air duct 36, used to guide the return air that converges through the freezer return air outlet 32 ​​and the refrigerator return air outlet 33 through the evaporator 42. The return air from the freezer compartment 11 and the refrigerator compartment 12 first enters the return air duct 36, and then is introduced into the evaporator 42 for cooling through the inlet side of the fan 41.

[0080] This embodiment enables air circulation between the freezer compartment 11 and the refrigerator compartment 12, improving refrigeration efficiency, reducing the space occupied by the refrigeration cycle component 4, making the overall structure of the refrigerator more compact and thinner, while improving the temperature uniformity and refrigeration effect of the refrigerator compartment 12 and the freezer compartment 11, and maintaining the freshness of the food.

[0081] In addition, the refrigeration cycle assembly also includes an air guide shroud, inside which a fan is installed. Both the refrigeration air inlet 31 and the refrigeration air inlet 21 are connected to the air guide shroud 43. The air guide shroud 43 is connected to the main frame 37 by bolts. A mounting groove is formed on one side of the main frame 37, matching the shape of the air guide shroud 43. The air guide shroud 43 has two outlet ends, corresponding to the refrigeration air inlet 31 and the refrigeration air inlet 21 respectively, allowing the fan 41 to drive cold air out from the corresponding outlet ends during rotation.

[0082] In some embodiments, such as Figures 1 to 6 As shown, the refrigeration cycle assembly 4 also includes a compressor 45, a condenser 44, and a throttling device. The compressor 45, the condenser 44, and the throttling device are all connected to the housing 1, and the compressor 45, the condenser 44, the throttling device, and the evaporator 42 are connected end to end in sequence.

[0083] In this embodiment, compressor 45 is responsible for compressing the low-temperature, low-pressure refrigerant vapor from evaporator 42 into high-temperature, high-pressure refrigerant vapor and discharging it. Condenser 44 cools and condenses the high-temperature, high-pressure refrigerant vapor discharged from compressor 45 into a liquid state. During this process, the refrigerant releases heat, which is absorbed by the surrounding environment. The throttling device is typically a capillary tube or expansion valve, which reduces the pressure and temperature of the refrigerant, transforming the high-pressure liquid refrigerant exiting condenser 44 into a low-temperature, low-pressure liquid refrigerant. Evaporator 42 is the part of the refrigeration system that exchanges heat with the object being cooled. The low-temperature, low-pressure refrigerant absorbs heat from the surrounding air in evaporator 42, thereby achieving a cooling effect.

[0084] During operation, compressor 45 starts working first. Compressor 45 draws in low-temperature, low-pressure refrigerant vapor from evaporator 42 and compresses it into high-temperature, high-pressure refrigerant vapor. The high-temperature, high-pressure refrigerant vapor enters condenser 44. In condenser 44, the refrigerant vapor exchanges heat with the surrounding environment, releasing heat and gradually cooling. As heat is released, the refrigerant vapor condenses into high-pressure liquid refrigerant. At this point, the refrigerant temperature is high, but it is still liquid. After flowing out of condenser 44, the high-pressure liquid refrigerant enters a throttling device (such as a capillary tube or expansion valve). The function of the throttling device is to reduce the pressure and temperature of the refrigerant. After passing through the throttling device, the refrigerant becomes a low-temperature, low-pressure liquid refrigerant, ready to enter evaporator 42. The low-temperature, low-pressure liquid refrigerant enters evaporator 42. In evaporator 42, the refrigerant exchanges heat with the surrounding air, absorbing heat from the air. As heat is absorbed, the refrigerant gradually evaporates into low-temperature, low-pressure vapor. The air passing through evaporator 42 is cooled, and its temperature decreases. The cooled air is then drawn in by fan 41 and delivered to the freezer compartment 11 and refrigerator compartment 12 through the outlet side of fan 41, achieving a cooling effect. Finally, the low-temperature, low-pressure refrigerant vapor flows out from evaporator 42 and is drawn back in by compressor 45, starting a new refrigeration cycle. The refrigeration equipment operates continuously, repeating the above process, which maintains the freezer compartment 11 and refrigerator compartment 12 at their normal operating temperature.

[0085] In conjunction with the above embodiments, a process window 381 is provided on the inner side plate 38, and a sealing cover plate 382 is detachably connected to the process window 381. In this embodiment, the process window 381 facilitates welding and subsequent maintenance.

[0086] Specifically, the refrigeration cycle assembly 4 includes piping for refrigerant flow. In this embodiment, the refrigeration cycle assembly 4 is located on the side wall of the freezer compartment 11. This method requires connecting the piping, which necessitates welding during the connection process. In this embodiment, the welding position is aligned with the process window 381, allowing welding to be performed through the process window 381 during the welding process. Furthermore, subsequent maintenance can be performed quickly through the process window 381, reducing later maintenance costs. The sealing cover plate 382 is detachably connected using screws or snap-fit ​​connections.

[0087] Based on the above embodiments, in some embodiments, such as Figures 1 to 6As shown, a portion of the refrigeration air duct assembly 3 extends to the back of the freezer compartment 11. A refrigeration air outlet 31 is formed at the location where the refrigeration air duct assembly 3 connects to the back, and the refrigeration air outlet 31 extends along the width of the freezer compartment 11. This allows the cold air blown out by the refrigeration air outlet 31 to cover as much of the area within the freezer compartment 11 as possible, resulting in a more uniform temperature in the freezer compartment 11 and improved cooling efficiency. The airflow direction of the refrigeration air outlet 31 is set at an angle to the back of the freezer compartment 11.

[0088] In this embodiment, the air supply direction of the refrigeration air outlet 31 is set at an angle to the back of the freezer chamber 11, that is, the air supply direction of the refrigeration air outlet 31 is tilted and faces the center of the freezer chamber 11, so that the refrigeration air outlet 31 can circulate better within the freezer chamber 11, improve cooling efficiency, and ensure cooling effect. Specifically, taking the refrigeration air duct assembly 3 located on the left side of the freezer chamber 11 as an example, the refrigeration air outlet 31 is located to the left rear of its location in the freezer chamber 11, so that the air supply direction of the refrigeration air outlet 31 faces the right front of its location in the freezer chamber 11, that is, the cold air blown out by the refrigeration air outlet 31 diffuses diagonally along the freezer chamber 11, ensuring that the temperature of its location in the freezer chamber 11 is more uniform and improving the cooling effect.

[0089] Furthermore, the refrigeration air outlet 31 is positioned close to the refrigeration air duct assembly 3, which shortens the flow path within the refrigeration air duct assembly 3, increases the air supply velocity, and reduces the volume and number of structural components that extend the refrigeration air outlet 31 to the middle of the refrigeration chamber 11, thereby reducing the manufacturing cost and difficulty of the structural components.

[0090] In some implementations, such as Figures 1 to 6 As shown, a mating part 371 is formed on the main frame 37. The mating part 371 is located at one end of the main frame 37 near the back of the freezer compartment and covers the freezer air outlet 31.

[0091] The mating part 371 mates with the side plate 39. This mating part 371 can either contact the side plate 39 or be connected to it; there are no restrictions on this. Since the mating part 371 is located at the back of the freezer compartment 11, the cold air in the first air supply duct 34 will first pass through the mating part 371 when it flows into the freezer air supply outlet 31. Because the mating part 371 covers part of the freezer air supply outlet 31, it can guide the cold air flow, adjusting the airflow direction as needed to improve the cold air output effect.

[0092] In some implementations, such as Figure 6 As shown, the mating part 371 has a first guide slope 3711, which covers part of the refrigeration air outlet 31. The first guide slope 3711 is inclined in the direction away from the back of the refrigeration chamber 11 along the air outlet direction.

[0093] It is understandable that the first guide slope 3711 is set relative to the rear wall. The first guide slope 3711 is set on the mating part 371 to guide the airflow direction. When the cold air reaches the mating part 371, it is tilted and delivered under the action of the first guide slope 3711. The first guide slope 3711 is tilted away from the rear wall along the airflow direction, that is, towards the middle of the freezer compartment 11, so as to guide the cold air to the middle of the freezer compartment 11 and blow it in a diagonal direction, so as to ensure that the temperature in the freezer compartment 11 is more uniform and improve the cooling effect.

[0094] In some embodiments, the side plate 39 has a first mating slope, and the mating part 371 has a second mating slope, with the first mating slope in contact with the second mating slope.

[0095] That is, the first mating inclined surface of the side plate 39 contacts the second mating inclined surface of the mating part 371, so that the mating part 371 and the side plate 39 mate. The contact between the mating part 371 and the side plate 39 through the inclined surface increases the contact area between the mating part 371 and the side plate 39, making the fit between the mating part 371 and the side plate 39 tighter. This allows the cold air to be blown to the center of the freezer compartment 11 under the guidance of the mating part 371 as much as possible, reducing the amount of cold air flowing out from the gap between the side plate 39 and the mating part 371.

[0096] Furthermore, the mating part 371 and the side plate 39 are in contact via inclined surfaces. When the side plate 39 is installed on the main frame 37, it can also play a guiding and positioning role. That is, through the contact between the first mating inclined surface and the second mating inclined surface, the side plate 39 and the main frame 37 are accurately positioned, thereby improving the guiding effect of the mating part 371.

[0097] Based on the above embodiments, such as Figures 1 to 6 As shown, the refrigeration duct assembly 3 also includes a return air duct structure 30, which is disposed between the freezer compartment 11 and the refrigerator compartment 12. The return air duct structure 30 includes a duct body 301 and a base 302. The base 302 is connected to the refrigeration duct assembly 3. One end of the duct body 301 extends to communicate with the refrigerator compartment 12, forming a refrigeration return air inlet 33 within the refrigerator compartment 12. The other end of the duct body 301 extends to communicate with the return air channel 36. The base 302 is arranged around the edge of the other end of the duct body 301. The duct body 301 guides air from the refrigerator compartment 12 to the return air channel 36 of the refrigeration duct assembly 3. The base 302 provides support and fixation for the duct body 301, ensuring the stability of the return air duct structure 30.

[0098] During operation, air from the refrigerator compartment 12 enters the duct body 301 through the refrigerator return air inlet 33. The air is guided along the duct body 301 to the return air duct 36 of the refrigeration air duct assembly 3. In the return air duct 36, the air from the refrigerator compartment 12 mixes with the air from the freezer compartment 11, and is then guided to the refrigeration cycle assembly for cooling. The cooled air is then sent through the outlet side of the fan into the first air supply duct 34 and the pre-embedded air duct 5, and finally enters the freezer compartment 11 and the refrigerator compartment 12 through the freezer air supply inlet 31 and the refrigerator air supply inlet 21, completing the refrigeration cycle.

[0099] The refrigerated return air vent 33 is located along the edge of the inner wall of the refrigerator compartment 12 in the depth direction, on the side of the refrigerator compartment 12 closest to its opening. The refrigerated return air vent 33 is located along the edge of the inner wall of the refrigerator compartment 12 in the depth direction, typically near the front or side of the refrigerator compartment (generally directly on the side of the opening closer to the door inside the compartment). This arrangement allows the refrigerated return air vent 33 to effectively cover the entire depth direction of the refrigerator compartment, ensuring that air is evenly drawn from all parts of the refrigerator compartment.

[0100] During operation, air from the refrigerator compartment 12 is introduced into the return air duct structure 30 through the refrigerator return air inlet 33 located on the inner side wall edge. The introduced air is then transported through the return air duct structure 30 to the return air channel 36 of the freezer air duct assembly 3. In the return air channel 36, the air from the refrigerator compartment 12 mixes with the air from the freezer compartment 11 and is then guided to the refrigeration cycle assembly for cooling. Cooling air delivery: The cooled air is delivered through the outlet side of the fan into the first air supply channel 34 and the pre-embedded air duct 5, and finally enters the freezer compartment 11 and the refrigerator compartment 12 through the freezer air supply inlet 31 and the refrigerator air supply inlet 21. Since the refrigerator air duct assembly 2 in the refrigerator compartment 12 is located at the back of the refrigerator compartment, the air delivered by the refrigerator air supply inlet 21 blows out from the back of the refrigerator compartment 12 and is introduced by the refrigerator return air inlet 33 near the door and side wall, which can effectively cover the entire depth direction of the refrigerator compartment and ensure the cooling effect of the refrigerator compartment 12.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and should be covered within the scope of the claims of the present invention.
