Technical Field

[0003] This invention relates to the field of household appliances, and more particularly to a refrigeration device. Background Technology

[0004] In recent years, the trend of pursuing efficient space utilization in home furnishings has become increasingly prominent, with more and more consumers favoring ultra-thin models when purchasing refrigeration equipment. Refrigeration equipment uses refrigerant to complete the cooling task of the refrigerator and freezer chambers through a circulation loop, which helps to control the overall space occupied by the refrigeration equipment.

[0005] In related technologies, the back-mounted air duct refrigeration system commonly used in refrigeration equipment requires a considerable amount of space to be reserved at the back of the refrigeration equipment for air duct layout and heat dissipation due to its structural characteristics. This inevitably encroaches on the overall depth of the cabinet, resulting in low utilization of the internal depth space of the refrigeration equipment.

[0006] Food needs to be refrigerated during storage to maintain its quality and prevent spoilage. Everyday food mainly includes vegetables, meat, eggs, and leftovers used for cooking in the kitchen, as well as fruits, snacks, and beverages that can be eaten directly in restaurants. In related technologies, these two types of food are often placed in the same refrigeration chamber, which can easily lead to cross-contamination of flavors and affect the taste of the food.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0118] In the prior art, the overall air duct structure of the refrigeration equipment is usually arranged on the back side wall in the depth direction of the refrigeration equipment. This method makes the thickness of the refrigeration equipment greater for the same volume, and occupies a lot of space in the thickness direction.

[0119] To address the aforementioned problems, this application proposes a refrigeration device, as shown in Figures 1 to 6. While the refrigeration device is used as an example, it should be understood that the refrigeration device of this application can also be used as a freezer or any other suitable device.

[0120] In one embodiment of this application, as shown in Figures 1 to 6, the refrigeration equipment includes: a housing 1, a refrigerated air duct assembly 2, a frozen air duct assembly 3, and a refrigeration cycle assembly 4. The housing 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 disposed on the inner wall of the back of the refrigerator compartment 12, and has a refrigerated air inlet 21 located in the refrigerator compartment 12. The refrigerated air inlet 21 communicates with the refrigerated air duct assembly 2. The frozen air duct assembly 3 communicates with the refrigerated air duct assembly 2 and is disposed on the inner 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 frozen air inlet 31, a frozen air return inlet 32, and a refrigerated air return inlet 33 communicating with the refrigerated air duct assembly 3. The frozen air inlet 31 is located in the freezer compartment 11, the frozen air return inlet 32 ​​is located in the freezer compartment 11, and the refrigerated air return inlet 33 extends into the refrigerator compartment 12. 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 direction of the freezer compartment 11, allowing 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. A refrigeration circulation assembly 4 is disposed within the refrigeration air duct assembly 3, used to cool the air introduced by the refrigeration return air outlet 32 ​​and the refrigerator return air outlet 33, and then blow it out through the refrigerator air outlet 21 and the refrigeration air outlet 31.

[0121] Specifically, as shown in Figure 1, 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 conventional refrigeration equipment. That is, the refrigerator compartment 12 is located above the freezer compartment 11. Multiple partitions are installed within both the freezer and refrigerator compartments to divide the space into multiple layers for storing food. The freezer and refrigerator compartments 11 and 12 are independent of each other and can store different types of food. For example, the freezer compartment 11 can store ingredients for kitchen cooking, such as meat, while the refrigerator compartment 12 can store snacks, beverages, and other foods intended for direct consumption in the dining area, thus separating the kitchen and dining areas.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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 internal temperature of the refrigeration equipment.

[0126] This application places the refrigeration air duct assembly 2 on the inner wall of the back of the refrigeration compartment 12 and the freezing air duct assembly 3 on the inner wall of the freezing compartment 11 in the depth direction. Since the refrigeration circulation assembly 4 is not placed inside the refrigeration compartment 12, but rather placed within the freezing air duct assembly 3, space occupation in the depth direction is avoided, effectively improving the space utilization of the refrigeration equipment in the depth direction and making the overall thickness of the refrigeration equipment thinner. This refrigeration equipment can simultaneously draw return air from both the freezing compartment 11 and the refrigeration compartment 12, perform a centralized cooling process within the freezing air duct assembly 3, and then blow it back to its respective compartment 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 refrigeration compartment 12, simplifies the single-system structure, and greatly reduces or even eliminates the space occupation at the back of the refrigeration equipment.

[0127] Based on the above embodiments, in some embodiments, as shown in Figures 1 to 6, 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 direction 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. Simultaneously, the airflow direction of the refrigeration air outlet 31 is set at an angle to the back of the freezer compartment 11.

[0128] 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.

[0129] 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.

[0130] Since the refrigeration air duct assembly 2 is located on the inner wall at the back of the refrigeration compartment 12, and the freezing air duct assembly 3 is located on the inner wall in the depth direction of the freezing compartment 11, in order to connect the two, as shown in Figures 1 to 6, the refrigeration equipment also includes: a pre-embedded air duct 5, which is located between the freezing compartment 11 and the refrigeration compartment 12. One end of the pre-embedded air duct 5 extends to connect with the refrigeration air duct assembly 2, and the other end of the pre-embedded air duct 5 extends to connect with the freezing air duct assembly 3.

[0131] 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.

[0132] 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.

[0133] In some embodiments, as shown in Figures 1 to 6, the pre-embedded air duct 5 includes: a first extension 51, a connecting part 53, and a second extension 52 connected in sequence.

[0134] The first extension 51 extends to the area at the back of the freezer compartment 11 and is sealed to the second air supply channel 22 of the refrigeration air duct assembly 2; the second extension 52 extends to the side area of ​​the freezer compartment 11 and is sealed to the refrigeration air duct assembly 2, communicating with the first air supply channel 34 of the freezer air duct assembly 3.

[0135] The first extension 51, the connecting part 53, and the second extension 52 are integrally formed. The first extension 51 extends upward in the horizontal direction to connect with the refrigerated air duct assembly 2, and its end is sealed to the second air supply channel 22 of the refrigerated air duct assembly 2. The connecting part 53 serves as a transition section between the first extension 51 and the second extension 52, and the second extension 52 extends downward in the horizontal direction to connect with the refrigerated air duct assembly 3.

[0136] During operation, the refrigeration cycle assembly 4 cools the air within the equipment installation cavity, generating a low-temperature cold airflow. The cooled air is then delivered from the fan's outlet side into the first air supply channel 34 of the refrigeration air duct assembly 3 and the pre-embedded air duct 5. Within the pre-embedded air duct 5, the cold airflow first enters the second extension 52, then transitions through the connecting part 53 to the first extension 51. The first extension 51 guides the cold airflow to the second air supply channel 22 of the refrigeration air duct assembly 2. The cold airflow then passes through the second air supply channel 22 of the refrigeration air duct assembly 2 and finally enters the refrigerator compartment 12 through the refrigeration air outlet 21, achieving a cooling effect on the refrigerator compartment.

[0137] Based on the above embodiments, in some embodiments, as shown in Figures 1 to 6, a first air supply channel 34, an equipment mounting cavity 35, and a return air channel 36 are formed within the refrigeration air duct assembly 3. The refrigeration air duct assembly 2 and the inner wall of the refrigeration chamber 12 enclose a second air supply channel 22. The refrigeration circulation assembly 4 is disposed within the equipment mounting cavity 35. The first side of the equipment mounting cavity 35 is connected to the refrigeration chamber 11 sequentially through the first air supply channel 34 and the refrigeration air supply outlet 31. The second side of the equipment mounting cavity 35 is connected to the refrigeration chamber 12 sequentially through the pre-embedded air duct 5, the second air supply channel 22, and the refrigeration air supply outlet 21. The third side of the equipment mounting cavity 35 is connected to the refrigeration chamber 11 sequentially through the return air channel 36 and the refrigeration return air outlet 32. The third side of the equipment mounting cavity 35 is connected to the refrigeration chamber 12 sequentially through the return air channel 36 and the refrigeration return air outlet 33.

[0138] 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.

[0139] 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.

[0140] In some embodiments, as shown in Figures 4 to 6, 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 channel 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 channel 34.

[0141] 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.

[0142] 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.

[0143] In addition, the refrigeration air duct assembly 3 also includes a connecting pipe 361, which is installed in the inner liner mechanism between the freezer compartment 11 and the refrigerator compartment 12. The connecting pipe 361 is provided with a refrigerator return air vent 33 and is connected to the return air channel 36 to realize the return air flow in the refrigerator compartment 12.

[0144] 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.

[0145] In some embodiments, as shown in Figures 4 to 6, 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.

[0146] 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.

[0147] The shape and size of the refrigeration air outlets 31 can be optimized according to the actual needs of the freezer compartment 11 to achieve the best airflow effect. The arrangement of the refrigeration air outlets 31 can also be adjusted according to the size and shape of the freezer compartment 11 to adapt to different refrigeration equipment models and designs. For example, when the refrigeration demand is small, the number and size of the refrigeration air outlets 31 can be reduced. Conversely, when the refrigeration demand is large, the number and size of the refrigeration air outlets 31 can be increased.

[0148] 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.

[0149] In some embodiments, as shown in Figures 4 and 5, the refrigerated air duct assembly 2 includes: a main body molding 23 and an inner connecting plate 24; the inner connecting plate 24 is connected to the main body molding 23 and located within the refrigerated compartment 12; a channel groove is formed on the main body molding 23, and the channel groove and the inner sidewall of the refrigerated compartment 12 enclose the second air supply channel 22. It is understood that this method enables the main body molding 23 to cooperate with the sidewall of the refrigerated compartment 12, thereby forming the second air supply channel 22. The second air supply channel 22 enables the delivery of cold air, and the cooperation with the sidewall of the refrigerated compartment 12 makes the overall structure more compact, allowing for higher utilization of internal space.

[0150] In some embodiments, as shown in Figures 5 and 6, the refrigeration equipment further includes a damper assembly 6. The damper assembly 6 protrudes from the back of the refrigerator compartment 12 and is connected to the inner wall of the back of the refrigerator compartment 12 and / or the refrigerated air duct assembly 2. A connecting channel is formed between the damper assembly 6 and the inner wall of the back of the refrigerator compartment 12 and / or the refrigerated air duct assembly 2. One end of the connecting channel communicates with the pre-embedded air duct 5, and the other end communicates with the second air supply duct 22. The damper assembly 6 controls the opening and closing of the second air supply duct 22 and can also control the air intake volume of the second air supply duct 22. The other end of the second air supply duct 22 communicates with the refrigerator compartment 12, thereby enabling control of the entry of cold air.

[0151] The damper assembly 6 includes a damper body 61 and a damper housing 62. The damper body 61 is used to control the airflow into the second air supply channel 22. The damper body 61 is installed in the pre-embedded air duct 5 and can adjust the opening degree as needed to control the amount of cold air flowing into the second air supply channel 22. The connecting channel is formed by the damper housing 62, the refrigerated air duct assembly 2, and the damper body 61.

[0152] The damper housing 62 includes a damper outer shell and a damper molding component. The damper molding component is fixed to the outside of the refrigerated air duct assembly 2. The damper molding component is fixed to the outer side of the refrigerated air duct assembly 2, while the damper outer shell cooperates with the damper molding component and is connected to the outermost side of the damper molding component to form the overall structure of the damper assembly 6.

[0153] Specifically, the damper assembly 6 typically adopts a mature modular design, which can be directly installed on the back of the refrigerator compartment 12 or on the refrigerated air duct assembly 2 as needed, or partly on the back of the refrigerator compartment 12 and partly on the refrigerated air duct assembly 2. Its damper housing and damper molding are used to firmly connect to the refrigerated air duct assembly 2 and form a sealed connection channel. One end of this channel connects to the pre-embedded air duct 5, and the other end connects to the second air supply channel 22. At the same time, the damper body 61 is also equipped with a baffle / damper plate. The baffle is supported in the housing by a rotating shaft (pivot) and is equipped with a low-temperature aging resistant seal to ensure that it can effectively prevent airflow leakage when closed. The rotational movement of the baffle is driven by a precision stepper motor, which precisely converts the motor's rotational torque into the required angle displacement of the baffle through a transmission mechanism (such as a gearbox, coupling, or connecting rod). This allows the damper body 61 to not only execute the opening or closing command of the second air supply channel, but also to achieve continuous stepless or step-by-step precise adjustment of the air intake volume (cold air flow) of the channel, thereby accurately controlling the amount of cold air entering the refrigerator compartment 12 according to its temperature requirements.

[0154] The damper assembly 6 can also adopt other mature damper assembly 6 structures, so the specific structure of the damper assembly 6 is not limited here.

[0155] In some embodiments, as shown in Figures 1 to 5, 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, typically 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.

[0156] 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.

[0157] 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.

[0158] In some embodiments, as shown in Figures 1 to 6, the refrigeration cycle assembly 4 includes a fan 41 and an evaporator 42, both of which are disposed within the equipment mounting cavity 35. The fan 41 has an air inlet side and an air outlet side, and 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, for sending 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, for guiding the return air that converges through the freezer return air inlet 32 ​​and the refrigerator return air inlet 33 to flow through the evaporator 42.

[0159] 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.

[0160] 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 refrigeration equipment 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.

[0161] 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.

[0162] In some embodiments, as shown in Figures 1 to 6, the refrigeration cycle assembly 4 further 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.

[0163] 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.

[0164] 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.

[0165] 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.

[0166] 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.

[0167] In some embodiments, as shown in Figures 1 to 6, 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 11 and covers the freezer air outlet 31.

[0168] 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.

[0169] In some embodiments, as shown in FIG6, the mating part 371 has a first guide slope 3711, which covers a portion of the refrigeration air outlet 31 and is inclined in the direction away from the back of the refrigeration chamber 11 along the air outlet direction.

[0170] 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.

[0171] 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.

[0172] 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.

[0173] 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.

[0174] Food needs to be refrigerated during storage to maintain its quality and prevent spoilage. Everyday food mainly includes vegetables, meat, eggs, and leftovers used for cooking in the kitchen, as well as fruits, snacks, and beverages that can be eaten directly in restaurants. In related technologies, these two types of food are often placed in the same refrigeration chamber, which can easily lead to cross-contamination of flavors and affect the taste of the food. To improve the problems existing in related technologies, this application provides a refrigeration device that can simultaneously function as two refrigeration devices, thereby achieving separation of the kitchen and dining areas, minimizing cross-contamination of flavors between the first and second chambers, and improving the quality of food storage.

[0175] This application is described below with reference to the accompanying drawings and specific embodiments:

[0176] Please refer to Figures 7-9. This application provides a refrigeration device 10A that can realize the function of two refrigeration devices at the same time, thereby achieving separation of the kitchen and dining areas, minimizing the cross-contamination of odors between the first and second chambers, and improving the storage quality of food.

[0177] In this embodiment, the refrigeration device 10A can be a freezer or a refrigeration device. For ease of description, this embodiment uses the example of refrigeration device 10A being a refrigeration device. The same principle applies when refrigeration device 10A is another type of device.

[0178] Referring to Figures 7-9, in this embodiment, the refrigeration device 10A includes a housing 100A, a first air duct module 200A, and a second air duct module 200A'. The housing 100A has independent first chambers 110A and 110A'. The first chamber 110A includes a first refrigerator chamber 113A and a first freezer chamber 114A, and the second chamber 110A' includes a second refrigerator chamber 113A' and a second freezer chamber 114A'. The first air duct module 200A is installed in the first chamber 110A to supply air to the first refrigerator chamber 113A and the first freezer chamber 114A; the second air duct module 200A' is installed in the second chamber 110A' to supply air to the second refrigerator chamber 113A' and the second freezer chamber 114A'.

[0179] The enclosure 100A is roughly rectangular. For ease of description, the height direction (Z), width direction (X), and thickness direction are defined. In the operating state of the refrigeration equipment 10A, the vertical direction is the height direction (Z), and the projection of the enclosure 100A in the vertical direction is a rectangle. The direction of the longer side is the width direction (X), and the direction of the shorter side is the thickness direction.

[0180] Similarly, for ease of description, six directions are defined: up, down, left, right, front, and back. In the height direction Z, up is closer to the top surface and down is further from the top surface; in the width direction X, left and right are respectively. The housing 100A has an opening; in the thickness direction, front is closer to the opening and back is further from the opening.

[0181] The housing 100A is the main structure of the entire refrigeration equipment 10A, providing a mounting base for the air duct module, compressor, evaporator, and other structures, and also protecting the aforementioned electronic components. The housing 100A has two independent chambers: a first chamber 110A and a second chamber 110A'. The first chamber 110A includes a first refrigeration chamber 113A and a first freezing chamber 114A. The second chamber 110A' includes a second refrigeration chamber 113A' and a second freezing chamber 114A'. The first and second refrigeration chambers 113A and 113A' are used for refrigerating items, while the first and second freezing chambers 114A and 114A' are used for freezing items. Specifically, the first and second chambers 110A and 110A' can be arranged side-by-side along the width direction X of the housing 100A, with the first freezing chamber 114A located below the first refrigeration chamber 113A, and the second freezing chamber 114A' located below the second refrigeration chamber 113A'.

[0182] Since the first chamber 110A and the second chamber 110A' are independent of each other, and both the first chamber 110A and the second chamber 110A' have refrigeration and freezing functions, the first chamber 110A and the second chamber 110A' can store different types of food. For example, the first chamber 110A can store ingredients used for cooking in the kitchen, such as meat, vegetables, eggs, etc., while the second chamber 110A' can store snacks, beverages, etc. that are eaten directly in the restaurant, thus achieving separation of the kitchen and dining areas.

[0183] Since the first air duct module 200A is installed in the first chamber 110A to supply air to the first refrigerator chamber 113A and the first freezer chamber 114A, and the second air duct module 200A' is installed in the second chamber 110A' to supply air to the second refrigerator chamber 113A' and the second freezer chamber 114A', the first refrigerator chamber 113A and the first freezer chamber 114A share a set of air duct modules, and the second refrigerator chamber 113A' and the second freezer chamber 114A' share a set of air duct modules. There is no gas circulation between the first chamber 110A and the second chamber 110A'. This minimizes the cross-contamination of odors between the first refrigerator chamber 113A and the second refrigerator chamber 113A', and between the first freezer chamber 114A and the second freezer chamber 114A', thus improving the quality of food storage.

[0184] In summary, since the first chamber 110A and the second chamber 110A' each operate independently using a separate set of air duct modules, and both the first chamber 110A and the second chamber 110A' have refrigeration and freezing functions, the first chamber 110A and the second chamber 110A' can be regarded as separate refrigeration devices 10A. That is, the refrigeration device 10A provided in this application embodiment can realize the function of two refrigeration devices 10A at the same time, so as to improve the problem of cross-contamination of flavors while ensuring the amount of food stored.

[0185] It should be noted that the structures of the first air duct module 200A and the second air duct module 200A' are completely identical. This article will use the structure of the first air duct module 200A as an example for specific explanation, and the structure of the second air duct module 200A' can be deduced by analogy.

[0186] In some embodiments, the first air duct module 200A includes a first air outlet assembly 210A and a first air supply assembly 220A. The first air outlet assembly 210A is installed in the first refrigeration chamber 113A, and the first air supply assembly 220A is installed in the first freezing chamber 114A. The first air outlet assembly 210A is communicative with the first air supply assembly 220A, allowing cold air from the first air supply assembly 220A to enter the first air outlet assembly 210A.

[0187] The first air outlet assembly 210A is installed inside the first refrigerator compartment 113A to blow cold air into the first refrigerator compartment 113A, and the first air supply assembly 220A is installed inside the first freezer compartment 114A to blow cold air into the first freezer compartment 114A. Since the first air outlet assembly 210A can communicate with the first air supply assembly 220A, the cold air in the first air supply assembly 220A enters the first air outlet assembly 210A, thereby allowing the first air outlet assembly 210A to supply air into the first refrigerator compartment 113A.

[0188] Similarly, the second air duct module 200A' includes a second air outlet component 210A' and a second air supply component 220A'. The second air outlet component 210A' is installed in the second refrigeration chamber 113A', and the second air supply component 220A' is installed in the second freezing chamber 114A'. The second air outlet component 210A' can communicate with the second air supply component 220A', so that the cold air in the second air supply component 220A' enters the second air outlet component 210A'.

[0189] The second air outlet assembly 210A' is installed inside the second refrigerator compartment 113A' to blow cold air into the second refrigerator compartment 113A', and the second air supply assembly 220A' is installed inside the second freezer compartment 114A' to blow cold air into the second freezer compartment 114A'. Since the second air outlet assembly 210A' can communicate with the second air supply assembly 220A', the cold air in the second air supply assembly 220A' enters the second air outlet assembly 210A', thereby allowing the second air outlet assembly 210A' to supply air into the second refrigerator compartment 113A'.

[0190] Please refer to Figures 10-12. In some embodiments, the first air duct module 200A further includes a first mounting member 230A and a first damper 240A. The first mounting member 230A is mounted on the housing 100A. The first mounting member 230A has a first air supply channel 231A that can connect the first air outlet assembly 210A and the first air supply assembly 220A. The first damper 240A is mounted on the first mounting member 230A and can open or close the first air supply channel 231A.

[0191] The first damper 240A connects or separates the first air outlet assembly 210A and the first air supply assembly 220A by opening or closing the first air supply channel 231A. The first damper 240A can open or close the first air supply channel 231A by rotation. When the first damper 240A opens the first air supply channel 231A, the first air supply channel 231A connects the first air outlet assembly 210A and the first air supply assembly 220A, and the cold air in the first air supply assembly 220A enters the first air outlet assembly 210A through the first air supply channel 231A. When the first damper 240A closes the first air supply channel 231A, that is, when the first damper 240A covers the first air supply channel 231A, the first air outlet assembly 210A and the first air supply assembly 220A are separated. Of course, the first damper 240A can also adjust its opening degree to control the airflow and thus adjust the temperature of the first refrigeration chamber 113A.

[0192] Similarly, the second air duct module 200A' also includes a second mounting component 230A' and a second damper 240A'. The second mounting component 230A' is mounted on the housing 100A. The second mounting component 230A' has a second air supply channel 231A' that can connect the second air outlet assembly 210A' and the second air supply assembly 220A'. The second damper 240A' is mounted on the second mounting component 230A' and can open or close the second air supply channel 231A'.

[0193] Please refer to Figures 10-12. In some embodiments, the first air outlet assembly 210A has a first air outlet duct 211A, and the first air supply assembly 220A includes a first housing 221A, a first air supply duct 222A, a first fan 223A, and a first evaporator 224A. The first air supply duct 222A, the first fan 223A, and the first evaporator 224A are installed inside the first housing 221A, and the first air supply channel 231A can connect the first air outlet duct 211A and the first air supply duct 222A.

[0194] The first air outlet duct 211A is used to blow air into the first refrigeration chamber 113A, the first air supply duct 222A is used to blow air into the first freezing chamber 114A, and the first air damper 240A connects or separates the first air outlet duct 211A and the first air supply duct 222A by opening or closing the first air supply channel 231A.

[0195] The first evaporator 224A is used to cool the air, and the first fan 223A is used to circulate the cold air within the cavity. Since the first freezing cavity 114A requires a larger cooling capacity, the first fan 223A and the first evaporator 224A are installed inside the first housing 221A. Thus, the first evaporator 224A can directly cool the air in the first air supply duct 222A, and the resulting cold air can be blown into the first freezing cavity 114A. Under the action of the first fan 223A, the cold air can flow through the first air supply channel 231A to the first air outlet duct 211A, causing the first air outlet duct 211A to blow air into the first refrigeration cavity 113A. That is, the cold air in the first air outlet duct 211A and the first air supply duct 222A is cooled by the first evaporator 224A in the first housing 221A, and under the action of the first fan 223A, the cold air can circulate simultaneously in the first freezing cavity 114A and the first refrigeration cavity 113A.

[0196] Similarly, the second air outlet assembly 210A' has a second air outlet duct 211A', and the second air supply assembly 220A' includes a second housing 221A', a second air supply duct 222A', a second fan 223A', and a second evaporator 224A'. The second air supply duct 222A', the second fan 223A', and the second evaporator 224A' are installed inside the second housing 221A', and the second air supply channel 231A' can connect the second air outlet duct 211A' and the second air supply duct 222A'.

[0197] Please refer to Figures 10-12. In some embodiments, the first housing 221A further includes a first return air duct 225A, the first air outlet assembly 210A has a first refrigerated air outlet 212A and a first refrigerated return air outlet 213A communicating with the first air outlet duct 211A, the first housing 221A has a first refrigerated air outlet 226A and a first refrigerated return air outlet 227A communicating with the first air supply duct 222A, and the first refrigerated return air outlet 213A and the first refrigerated return air outlet 227A are communicating with the first return air duct 225A.

[0198] The first return air duct 225A is connected to the first supply air duct 222A. The first refrigerated air outlet 212A and the first refrigerated air return outlet 213A are both connected to the first refrigerated cavity 113A. The first freezer air outlet 226A and the first freezer air return outlet 227A are connected to the first freezer cavity 114A. Under the action of the first fan 223A, the cold air from the first air outlet duct 211A is blown into the first refrigerated cavity 113A through the first refrigerated air outlet 212A to cool the items inside the first refrigerated cavity 113A. Then, the cold air enters the first return air duct 225A through the first refrigerated return air inlet 213A. The cold air from the first supply air duct 222A is blown out through the first refrigeration air outlet 226A to cool the items in the first refrigeration chamber 114A. Then, the cold air enters the first return air duct 225A through the first refrigeration return air inlet 227A. The gas entering the first return air duct 225A is cooled again and then enters the first supply air duct 222A and the first outlet air duct 211A to achieve gas circulation and continuous cooling of the items.

[0199] Similarly, the second housing 221A' also has a second return air duct 225A', the second air outlet assembly 210A' has a second refrigerated air outlet 212A' and a second refrigerated return air outlet 213A' connected to the second air outlet duct 211A', the second housing 221A' has a second refrigerated air outlet 226A' and a second refrigerated return air outlet 227A' connected to the second air supply duct 222A', and the second refrigerated return air outlet 213A' and the second refrigerated return air outlet 227A' are connected to the second return air duct 225A'.

[0200] Please refer to Figures 10-12. In some embodiments, the first mounting component 230A also has a first return air channel 232A that communicates with the first return air duct 225A and the first return air channel 232A communicates with the first refrigerated return air inlet 213A.

[0201] Since the first return air duct 232A is connected to the first refrigerated return air inlet 213A, the air in the first refrigerated chamber 113A, after entering the first refrigerated return air inlet 213A, can flow through the first return air duct 232A to the first return air channel 225A, thus achieving gas circulation. That is, the air supplied from the first supply air channel 222A to the first outlet air channel 211A passes through the first supply air duct 231A, and the air in the first refrigerated chamber 113A returns to the first return air channel 225A through the first return air duct 232A. The first mounting component 230A can be used for both supply and return air, thereby making the structure of the air duct assembly more compact. Of course, since the first return air duct 225A and the first refrigeration return air inlet 227A are both located in the first refrigeration chamber 114A, the first refrigeration return air inlet 227A can be directly connected to the first return air duct 225A, so that the air in the first refrigeration chamber 114A can directly enter the first return air duct 225A through the first refrigeration return air inlet 227A to achieve gas circulation.

[0202] Similarly, the second mounting component 230A' also has a second return air duct 232A' that communicates with the second return air duct 225A' and the second return air duct 232A' that communicates with the second refrigerated return air inlet 213A'.

[0203] Please refer to Figures 8 and 9. In some embodiments, the housing 100A further includes an opening communicating with the first chamber 110A. The first chamber 110A has a first rear wall 112A and a first side wall 111A. The first rear wall 112A is disposed opposite to the opening, and the first rear wall 112A and the first side wall 111A are disposed at an angle. The first air duct module 200A is installed on the first side wall 111A.

[0204] The housing 100A has an opening through which a user can take out or put in items. The first chamber 110A has a first rear wall 112A and first side walls 111A. The first rear wall 112A is positioned opposite the opening. There are two first side walls 111A, each forming an angle with the first rear wall 112A. The first rear wall 112A is positioned opposite the opening in the depth direction (Y), and the two first side walls 111A are positioned opposite each other in the width direction (X). The first side walls 111A are perpendicular to the first rear wall 112A.

[0205] Since the first air outlet assembly 210A is installed on the first side wall 111A of the first refrigeration chamber 113A and the first air supply assembly 220A is installed on the first side wall 111A of the first freezing chamber 114A, neither the first air outlet assembly 210A nor the first air supply assembly 220A occupies space in the depth direction Y of the refrigeration equipment 10A. Thus, while meeting the ultra-thin requirements of the refrigeration equipment 10A, the space for storing items in the refrigeration equipment 10A can be guaranteed as much as possible.

[0206] It should be noted that since the first chamber 110A has two opposing first side walls 111A, the first air outlet assembly 210A can be installed on any one of the first side walls 111A of the first refrigeration chamber 113A, and the first air supply assembly 220A can be installed on any one of the first side walls 111A of the first freezing chamber 114A, without any limitation.

[0207] Similarly, the housing 100A also includes an opening communicating with the second chamber 110A'. The second chamber 110A' has a second rear wall 112A' and a second side wall 111A'. The second rear wall 112A' is disposed opposite to the opening, and the second rear wall 112A' and the second side wall 111A' are disposed at an angle. The second air duct module 200A' is installed on the second side wall 111A'.

[0208] Please refer to Figure 7. In some embodiments, the first air outlet assembly 210A and the first air supply assembly 220A are arranged on the same side.

[0209] Since the first air outlet assembly 210A and the first air supply assembly 220A share a set of first evaporator 224A and first fan 223A, the first air supply assembly 220A can communicate with the first air outlet assembly 210A to deliver cold air to the first air outlet assembly 210A. Furthermore, the air supply and return between the first air outlet assembly 210A and the first air supply assembly 220A are both delivered through the first mounting component 230A. Therefore, the first air outlet assembly 210A and the first air supply assembly 220A are set on the same side, which makes it easier to connect the first air outlet assembly 210A and the first air supply assembly 220A and facilitates the setting of the first mounting component 230A.

[0210] Similarly, the second air outlet assembly 210A' and the second air supply assembly 220A' are also located on the same side.

[0211] Specifically, the first air outlet assembly 210A and the first air supply assembly 220A can both be located on the left side of the first chamber 110A or both on the right side of the first chamber 110A. The second air outlet assembly 210A' and the second air supply assembly 220A' can both be located on the left side of the second chamber 110A' or both on the right side of the second chamber 110A', and there is no limitation on this.

[0212] The following describes the entire gas circulation process within the refrigeration equipment 10A provided in this application embodiment, taking the first air duct module 200A as an example. The same applies to the second air duct module 200A'.

[0213] After being cooled by the first evaporator 224A, the gas in the first air supply duct 222A is blown into the first freezing chamber 114A by the first refrigeration air outlet 226A under the action of the first fan 223A. This freezes the items in the first freezing chamber 114A. The gas then flows back to the first return air duct 225A through the first refrigeration return air outlet 227A. Another portion of the cold air enters the first air outlet duct 211A through the first air supply channel 231A and enters the refrigerator through the first refrigeration air outlet 212A to refrigerate the items in the first refrigeration chamber 113A. The gas then flows back to the first return air duct 225A through the first refrigeration return air outlet 213A and the first return air channel 232A, thus achieving gas circulation.

[0214] In summary, in the refrigeration device 10A provided in this application embodiment, since the first chamber 110A and the second chamber 110A' are independent of each other, and both the first chamber 110A and the second chamber 110A' have freezing and refrigeration functions, and the first chamber 110A and the second chamber 110A' do not share an air duct module, but each uses an independent set of air duct modules, one refrigeration device 10A can simultaneously have the functions of two refrigeration devices 10A. In this way, the cross-contamination of odors between the first refrigeration chamber 113A and the second refrigeration chamber 113A', and between the first freezing chamber 114A and the second freezing chamber 114A' can be minimized, thereby improving the storage quality of food.

[0215] In related technologies, the overall air duct structure of the refrigeration equipment is usually arranged on the back side wall of the refrigeration equipment in the depth direction X. This method makes the thickness of the refrigeration equipment thicker for the same volume, and occupies a lot of space in the thickness direction.

[0216] To address the problems in related technologies, as shown in Figures 13-18, this embodiment provides a refrigeration device, including a housing 10B, a first air duct assembly 20B, a refrigeration cycle assembly 40B, and a second air duct assembly 30B. The housing 10B includes a refrigerator chamber 12B and a freezer chamber 11B, with the refrigerator chamber 12B positioned above the freezer chamber 11B. The first air duct assembly 20B is connected to the side wall of the freezer chamber 11B on one side in the width direction Y, and the first air duct assembly 20B forms an installation chamber 211B, a first air inlet channel 216B, and a return air channel 212B. The first air inlet channel 216B is located on one side of the installation chamber 211B, and the return air channel 212B is located on the other side of the installation chamber 211B. The refrigeration cycle assembly 40B is disposed within the installation chamber 211B. The refrigeration cycle assembly 40B is used to cool and drive airflow; the second air duct assembly 30B is connected to the side wall of the refrigerator chamber 12B on the Y side in the width direction, and forms a second air inlet channel 311B with the side wall of the refrigerator chamber 12B; wherein, the refrigeration cycle assembly 40B has a first cold air output port 213B, a second cold air output port 214B and a return air port 215B communicating with the mounting chamber 211B. The first cold air output port 213B is connected to the freezer chamber 11B through the first air inlet channel 216B, the second cold air output port 214B is connected to the refrigerator chamber 12B through the second air inlet channel 311B, the return air port 215B is connected to the freezer chamber 11B, and the refrigerator chamber 12B is connected to the return air port 215B through the return air channel 212B. When the refrigeration equipment is refrigerating, it needs to transport the cooled cold air to the refrigeration chamber 12B or the freezing chamber 11B through the air duct. Usually, the air duct is constructed as a whole on the back plate in the depth direction X of the refrigeration equipment, which makes it difficult to optimize and control the overall thickness of the refrigeration equipment. In this embodiment, by setting the air duct assembly on the side wall in the width direction Y of the refrigeration equipment, it does not occupy the space in the depth direction X of the refrigeration equipment, thereby enabling control of the overall thickness of the refrigeration equipment and significantly reducing the overall thickness of the refrigeration equipment.

[0217] Specifically, as shown in Figure 13, the cabinet 10B includes an inner liner structure, which forms a refrigerator compartment 12B and a freezer compartment 11B. The two compartments are arranged vertically, similar to those in conventional refrigeration equipment. That is, the refrigerator compartment 12B is located above the freezer compartment 11B. Multiple partitions are provided within the freezer compartment 11B and the refrigerator compartment 12B to divide the space of the freezer compartment 11B and the refrigerator compartment 12B into multiple layers for accommodating food.

[0218] As shown in Figure 14, both the first air duct assembly 20B and the second air duct assembly 30B are external solid structures. During installation, the first air duct assembly 20B connects to the left or right side wall of the freezing chamber 11B (left and right sides are referenced in the diagram) and can also connect to the side wall of the refrigeration equipment. Within the first air duct assembly 20B are formed the mounting chamber 211B, the first air inlet channel 216B, and the return air channel 212B, as shown in Figures 16 and 17. The mounting chamber 211B is located between the first air inlet channel 216B and the return air channel 212B. The refrigeration cycle assembly 40B is located within the mounting chamber 211B and is used to cool the flowing air and drive the air to circulate. The second air duct assembly 30B is used to construct the second air inlet channel 311B for cold air flow, guiding cold air into the refrigeration chamber 12B, thereby lowering the temperature within the refrigeration chamber 12B.

[0219] Specifically, the refrigeration cycle assembly 40B has a component for refrigeration and a drive component for realizing cold air circulation. The refrigeration component cools the air, and the drive component drives the air to circulate and remove heat from the freezing chamber 11B and the refrigeration chamber 12B during the flow, thereby realizing the refrigeration operation inside the chamber.

[0220] In a specific implementation, the refrigeration cycle assembly 40B is composed of components commonly used in the prior art, such as a compressor, condenser, evaporator 42B, expansion valve, and fan 41B. The overall refrigeration process involves the compressor compressing low-pressure, low-temperature refrigerant gas into high-pressure, high-temperature gas. The high-pressure, high-temperature refrigerant gas flows into the condenser, releases heat, and transforms into a liquid state. The liquid refrigerant enters the evaporator 42B through the expansion valve (or capillary tube), where the pressure drops sharply and the temperature decreases accordingly. The low-temperature, low-pressure refrigerant absorbs heat from the circulating air inside the refrigeration equipment within the evaporator 42B, and the refrigerant turns into gas again, thereby reducing the internal temperature of the refrigeration equipment. The fan 41B drives the air inside the refrigeration equipment to circulate, thereby maintaining the stability of the low temperature inside the refrigeration equipment.

[0221] Understandably, in this example, the side wall thickness of the first air duct assembly 20B and the second air duct assembly 30B installed in the freezer chamber 11B and the refrigerator chamber 12B can be appropriately reduced, making them thinner than the side wall thickness of traditional refrigeration equipment. This allows for higher utilization of the space in the width direction Y of the chamber after the first air duct assembly 20B and the second air duct assembly 30B are installed, avoiding the occupation of chamber space due to the setting of the air duct assembly, and realizing full utilization of the chamber space of the refrigeration equipment.

[0222] When the air inside the refrigeration equipment circulates, it is first cooled and driven by the refrigeration cycle component 40B. The cooled air enters the freezing chamber 11B and the refrigeration chamber 12B through the first air inlet channel 216B and the second air inlet channel 311B, respectively, to cool the internal space of the freezing chamber 11B and the refrigeration chamber 12B. Driven by the refrigeration cycle component 40B, the air flows and circulates, thereby achieving continuous circulation of the internal space of the refrigeration equipment.

[0223] In specific applications, the first air duct assembly 20B has a first cold air output port 213B, a second cold air output port 214B, and a return air port 215B on the side plate 23B that forms the installation chamber 211B. The first cold air output port 213B and the second cold air output port 214B are both used to output cooled air for transportation. The transported air absorbs heat in the freezing chamber 11B or the refrigeration chamber 12B, and after absorbing heat, it enters the refrigeration cycle assembly 40B through the return air port 215B to recirculate and cool, thereby realizing the overall refrigeration cycle.

[0224] In conjunction with the above embodiments, the first air duct assembly 20B includes a main frame 21B, an inner side plate 22B, and a side plate 23B. The inner side plate 22B is fixedly disposed on one side of the main frame 21B and encloses to form an installation chamber 211B and a return air channel 212B. The side plate 23B is fixedly disposed on one side edge of the main frame 21B and encloses to form a first air inlet channel 216B. The first air duct assembly 20B is disposed on the side wall of the freezing chamber 11B and can realize the guidance and circulation of cold air. In this embodiment, the setting of the inner side plate 22B enables the solid frame structure inside the main frame 21B to enclose and construct different functional spaces. For example, the constructed installation chamber 211B is used for the installation of the refrigeration cycle assembly 40B, the constructed first air inlet channel 216B is connected to the freezing chamber 11B through the first cold air output port 213B to realize the guidance and delivery of cold air, and the constructed return air port 215B can realize the return flow of air after heat exchange in the freezing chamber 11B and the refrigeration chamber 12B to realize the overall air flow circulation refrigeration.

[0225] Specifically, the inner side plate 22B is located on the inner side surface of the main frame 21B, and the outer side surface of the main frame 21B is connected to the left wall of the freezer chamber 11B. An integral enclosure structure is formed on the main frame 21B, located in the middle of the main frame 21B and occupying most of its space. After the inner side plate 22B is connected to the main frame 21B, the space formed by the enclosure serves as the installation chamber 211B for the refrigeration cycle assembly 40B. An open return air port 215B is formed at the bottom of the enclosure. Return air from both the freezer chamber 11B and the refrigerator chamber 12B flows back through the return air port 215B and is recooled and returned to the circulation path by the refrigeration cycle assembly 40B. A gap exists between the side wall of the enclosure and the edge of the main frame 21B on that side, extending to the return air port 215B, thus forming a return air channel 212B to facilitate the return air recirculation within the refrigerator chamber 12B.

[0226] In the specific configuration, as shown in Figure 17, the main frame 21B has a first cold air output port 213B on the edge near the back plate of the freezer chamber 11B in the depth direction X. A recessed flow channel groove is formed on the side edge of this side. After being connected, the side plate 23B covers the flow channel groove to form a first air inlet channel 216B, which allows communication with the freezer chamber 11B. The main frame 21B has a second cold air output port 214B on the edge near the refrigerator chamber 12B. The second air inlet channel 311B communicates with the mounting chamber 211B through the second cold air output port 214B, thereby guiding cooling air into the refrigerator chamber 12B. In other words, by setting the first cold air port, the second cold air port, and the return air port 215B on the main frame 21B, the circulation of cooling air can be realized, maintaining the low temperature environment inside the refrigeration equipment. By setting them on the side wall, the overall thickness of the refrigeration equipment can be effectively reduced, achieving an ultra-thin structure that also accommodates large volume.

[0227] Understandably, the integral molding of the main frame 21B and the fixed connection of the inner side plate 22B and the side plate 23B facilitate the overall installation. Furthermore, this method integrates the first air inlet duct 216B, the return air duct 212B, and the installation chamber 211B, resulting in a more compact overall structure and efficient space utilization.

[0228] In conjunction with the above embodiments, a process window 222B is provided on the inner side plate 22B, and a sealing cover plate 24B is detachably connected to the process window 222B. When connecting the refrigeration cycle assembly 40B, the pipes on the evaporator 42B need to be welded. In this embodiment, the setting of the process window 222B facilitates welding and subsequent maintenance.

[0229] Specifically, the refrigeration cycle assembly 40B includes piping for refrigerant flow. In this embodiment, the refrigeration cycle assembly 40B is located on the side wall of the freezing chamber 11B. 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 222B, allowing welding to be performed through the process window 222B during the welding process. Furthermore, subsequent maintenance can be performed quickly through the process window 222B, reducing later maintenance costs. The sealing cover plate 24B is detachably connected using screws or snap-fit ​​mechanisms.

[0230] In the specific configuration, the inner side plate 22B has multiple partition support members 25B on its surface located in the freezing chamber 11B. These multiple partition support members 25B are evenly arranged in the vertical direction. As shown in Figure 16, two partition support members 25B are provided on the surface of the inner side plate 22B. One partition support member 25B is connected to the inner side plate 22B, and the other partition support member 25B is connected to the air vent cover.

[0231] In conjunction with the aforementioned inner side plate 22B structure, in a specific implementation, a refrigeration return air inlet 221B is provided at the bottom of the inner side plate 22B. The refrigeration return air inlet 221B is located away from the back plate of the refrigeration chamber 11B. The refrigeration return air inlet 221B is connected to the return air port 215B, so as to realize the return air gas in the refrigeration chamber 11B to flow back to the refrigeration cycle assembly 40B.

[0232] Specifically, a grille structure is provided inside the refrigeration return air vent 221B. This grille structure can prevent items stored in the cavity from clogging the refrigeration return air vent 221B, thereby improving the stability of gas circulation. Furthermore, the location of the refrigeration return air vent 221B near the back panel improves the uniformity of cold air, ensuring a more even temperature distribution inside the refrigeration equipment.

[0233] It is understandable that the cold air gradually absorbs heat and sinks in the refrigeration chamber 11B. After its inner side plate 22B is connected to the main frame 21B, it itself serves as the inner wall of the refrigeration chamber 11B. The bottom of the inner side plate 22B is also the bottom of the refrigeration chamber 11B. By setting the refrigeration return air vent 221B at the bottom position, the refrigeration chamber 11B can be effectively cooled, and the stability of the return flow can also be improved.

[0234] In conjunction with the above embodiments, the first air inlet channel 216B is provided with multiple refrigeration air outlets 217B. These outlets are positioned near the back panel of the refrigeration chamber 11B and are evenly spaced along the height Z direction of the refrigeration chamber 11B. Since temperatures may vary in different areas within the refrigeration chamber 11B, this embodiment utilizes multiple refrigeration air outlets 217B to deliver cooled air to different levels of the refrigeration chamber 11B, achieving uniform airflow and improving cooling quality.

[0235] Specifically, each refrigeration air inlet 217B is connected to the first air inlet channel 216B, and each partition has a corresponding refrigeration air inlet 217B. This design enables effective cooling of the space corresponding to each partition, improving cooling uniformity and achieving efficient cooling of each layer of the refrigeration chamber 11B. Furthermore, by placing the refrigeration air inlets 217B near the back panel and the refrigeration return air inlets 221B away from the back panel, the path of airflow is increased, thereby achieving efficient cooling of the refrigeration chamber 11B and improving the uniformity of cold air distribution.

[0236] In a specific configuration, the refrigeration air outlet 217B can be formed on the wall of the refrigeration chamber 11B to deliver cold air. In a preferred embodiment, it is formed directly by connecting the main frame 21B and the inner side plate 22B. As shown in Figure 17, the main frame 21B has three cold air delivery slots formed on the wall of the side of the main frame 21B near the back panel of the refrigeration equipment in the depth direction X. After the side plate 23B is connected, it covers the cold air delivery slots to form the refrigeration air outlet 217B, thereby delivering cold air.

[0237] In some embodiments, as shown in FIG18, the second air duct assembly 30B includes an air duct body 31B and an air duct panel 32B. The air duct panel 32B is connected to the air duct body 31B and is located within the refrigerator chamber 12B. A channel groove is formed on the air duct body 31B, and the channel groove and the side wall of the refrigerator chamber 12B enclose a second air inlet channel 311B. Multiple partition supports 25B are provided on the inner wall of the air duct panel 32B to support partitions. The refrigerator chamber 12B is a certain distance from the freezer chamber 11B, and the generated cold air needs to be transported into the refrigerator chamber 12B to cool the environment within the refrigerator chamber 12B. In this embodiment, the air duct body 31B is integrally formed with a channel groove, and one side of the channel groove is connected to the side wall of the refrigerator chamber 12B to form the second air inlet channel 311B, through which cold air can be transported.

[0238] As shown in Figures 14 and 19, in conjunction with the above embodiments, a transition structure 50B is provided at one end of the second air inlet channel near the freezing chamber 11B. The transition structure 50B is connected to the main air duct component 31B and has a transition air duct 53B connecting the second cold air output port 214B and the second air inlet channel 311B. The main air duct component 31B is connected to the refrigerator inner liner structure and provides a base for the installation support of the transition structure 50B. In this embodiment, the transition structure 50B enables adjustment of the air duct, allowing cold air to be accurately input into the second air inlet channel 311B.

[0239] Specifically, the adapter structure 50B is detachably connected to the main air duct component 31B, and the transition air duct 53B in the adapter structure 50B is used for cold air input into the second air inlet channel 311B. The detachable connection of the adapter structure 50B allows for quick adjustment, ensuring that the cold air output from the second cold air output port 214B accurately enters the second air inlet channel 311B, improving the quality of cold air delivery and the ease of adjustment. In other words, during the connection process between the adapter structure 50B and the main air duct component 31B, there is no need to move the entire main air duct component 31B; only the position of the adapter structure 50B needs to be adjusted to achieve precise connection between the second cold air output port 214B and the second air inlet channel 311B, thus greatly improving the convenience of connection between the second air inlet channel 311B and the second cold air output port 214B.

[0240] In the case where the adapter structure 50B is detachably connected to the air duct main body 31B, the adapter structure 50B and the air duct main body 31B can be fixedly connected or only in contact. The detachability between the adapter structure 50B and the air duct main body 31B means that the transition air duct 53B formed can be separated from the second air inlet channel 311B, so that the adapter structure 50B can be adjusted to connect the transition air duct 53B to the second air inlet channel 311B and the second cold air output port 214B respectively.

[0241] In conjunction with the above embodiments, the adapter structure 50B includes a first adapter 51B and a second adapter 52B. The first adapter 51B and the second adapter 52B are fixedly connected, and a transition air duct 53B is formed between the first adapter 51B and the second adapter 52B. The transition air duct 53B is used to realize the transition between the second cold air output port 214B and the second air inlet channel 311B. In this embodiment, the arrangement of the first adapter 51B and the second adapter 52B enables the overall structure of the transition air duct 53B to be formed, which facilitates the arrangement of the adapter structure 50B.

[0242] Specifically, both the first adapter 51B and the second adapter 52B have groove structures on their contact surfaces, which allows the grooves of the first adapter 51B and the second adapter 52B to enclose each other and form a transition air duct 53B after they are connected, thereby realizing the connection between the first adapter 51B and the second adapter 52B and the second cold air output port 214B.

[0243] In conjunction with the above embodiments, the transition structure 50B further includes a separator 54B. The separator 54B is located near the end of the second cold air output port 214B. The separator 54B has an air vent 541B for connecting the transition air duct 53B and the second cold air output port 214B. The air vent 541B is provided with a damper assembly 60B, which is used to control the opening and closing of the second air inlet channel 311B.

[0244] Specifically, the separator 54B has two side-by-side air vents 541B, each of which has a damper assembly 60B. The damper assembly 60B can open or close the air vent 541B. When the air vent 541B is open, the second air inlet channel 311B is open; when the air vent 541B is closed, the second air inlet channel 311B is closed.

[0245] Further, as shown in Figure 14, the bottom end of the second air inlet channel 311B is provided with a damper assembly 60B transition structure 50B. The bottom of the transition structure 50B is provided with a partition 54B. Within the partition 54B is a damper assembly 60B for controlling the opening and closing of the second air inlet channel 311B. Simultaneously, the damper assembly 60B can also control the air intake volume of the second air inlet channel 311B by adjusting its opening degree. One end of the second air inlet channel 311B is connected to the refrigeration chamber 12B, thereby enabling control of the cold air intake. The damper assembly 60B adopts a mature damper assembly structure, therefore, the specific structure of the damper assembly 60B is not limited here.

[0246] Understandably, this method enables the air duct main component 31B to cooperate with the side wall of the refrigeration chamber 12B, thereby forming a second air intake channel 311B. The second air intake channel 311B enables the delivery of cold air, and the cooperation with the side wall of the refrigeration chamber 12B makes the overall structure more compact, allowing for higher utilization of the internal space.

[0247] As shown in Figure 13, in conjunction with the above embodiments, a refrigerated return air vent 321B is provided at the bottom of the air duct panel 32B. The refrigerated return air vent 321B is located on the side away from the back panel of the refrigerated chamber 12B and is connected to the return air channel 212B. After absorbing heat in the refrigerated chamber 12B, the cold air needs to flow back to form a circulation in order to maintain a stable ambient temperature in the refrigerated chamber 12B. In this embodiment, by setting the refrigerated return air at the bottom and away from the back panel, the cold air distribution can be more uniform, improving the cooling efficiency and preventing localized low temperatures and frost formation.

[0248] Specifically, after passing through the refrigeration chamber 12B, the cold air gradually sinks and can be recirculated through the refrigeration return air vent 321B, thereby forming a cold air circulation and maintaining the stability of the internal temperature of the refrigeration chamber 12B.

[0249] In the above embodiments, at least one refrigerated air outlet 312B is provided at the extended end of the second air inlet channel 311B. The refrigerated air outlet 312B is located near the back plate of the refrigerated chamber 12B and is arranged in the upper region of the refrigerated chamber 12B. After entering the refrigerated chamber 12B, the cold air gradually sinks and absorbs heat in the process. This embodiment achieves uniform distribution of cold air by placing the refrigerated air outlet 312B in the upper region, which can effectively maintain the overall temperature stability.

[0250] Specifically, as shown in Figure 18, two refrigerated air inlets 312B are provided at the extended end of the second air inlet. A connecting port is provided at the corresponding position on the air duct panel 32B, connecting to the refrigerated air inlets 312B, thereby delivering cold air into the refrigerated chamber 12B. The two refrigerated air inlets 312B enable the delivery of cold air. Furthermore, by placing the refrigerated air inlets 312B near the back panel and the refrigerated return air inlet 321B on the side away from the chamber back panel, the cold air can be fully distributed within the chamber space, avoiding excessively low or high local temperatures and improving the uniformity and stability of the temperature within the chamber. Additionally, multiple partition support members 25B are provided on the inner wall of the air duct panel 32B, spaced vertically to support the partitions.

[0251] It is understandable that the refrigeration chamber 12B has a lower demand for cold air compared to the freezing chamber 11B. In this embodiment, a refrigeration air outlet 312B is provided in the upper area of ​​the refrigeration chamber 12B so that the cold air can descend naturally, avoiding direct blowing on the food and causing it to freeze, which helps to distribute the cold air evenly.

[0252] In some embodiments, the refrigeration cycle assembly 40B includes a fan 41B and an evaporator 42B. The fan 41B is located above the mounting chamber 211B and above the evaporator 42B. The bottom of the evaporator 42B is located within the return air port 215B. The evaporator 42B cools the circulating cold air, thereby achieving cooling of the entire air circulation loop. In this embodiment, by placing the fan 41B above the evaporator 42B and connecting the bottom of the evaporator 42B to the return air port 215B, effective cooling of the return air can be achieved, causing it to flow from the bottom of the evaporator 42B upwards, thus improving cooling efficiency.

[0253] Specifically, during the rotation of the fan 41B, its blades can drive the air flow in the area and create positive pressure at the first cold air outlet 213B and the second cold air outlet 214B to drive the air flow, while creating negative pressure on the side near the evaporator 42B to absorb the gas cooled by the evaporator 42B, thereby driving the entire cold air cycle.

[0254] In a specific implementation, as shown in Figures 14 and 17, the evaporator 42B has a spirally wound return pipe that connects to one end of the compressor. The return pipe requires welding during the connection process. In a specific configuration, the welding position of the return pipe is located within the area corresponding to the process window 222B, thereby facilitating welding.

[0255] In conjunction with the above embodiments, the refrigeration cycle assembly 40B also includes an air guide shroud 43B, a fan 41B installed inside the air guide shroud 43B, and the first cold air outlet 213B and the second cold air outlet 214B are both connected to the air guide shroud 43B.

[0256] Specifically, the air guide shroud 43B is connected to the main frame 21B by bolts, and a mounting groove is formed on one side of the main frame, which matches the shape of the air guide shroud 43B. The air guide shroud 43B has two outlet ends, which correspond to the first cold air outlet 213B and the second cold air outlet 214B, respectively, so that the fan 41B can drive cold air to be output from the corresponding outlet ends during rotation.

[0257] In some embodiments, the first air duct assembly 20B and the second air duct assembly 30B are located on the same side of the housing 10B in the width direction Y. This same-side arrangement facilitates overall processing and installation, and also shortens the flow path of the second air inlet channel 311B, thereby improving cooling efficiency and reducing the loss of cold air.

[0258] It is understandable that during the cooling air delivery process, the longer the delivery path, the greater the consumption and the greater the loss of cooling capacity. This embodiment, by placing the first air duct assembly 20B and the second air duct assembly 30B on the same side, can shorten the flow path of the cooling air, thereby improving the overall cooling efficiency.

[0259] Through the above description of the embodiments, those skilled in the art can clearly understand that by arranging the air ducts on the side walls of the refrigeration chamber 12B and the freezing chamber 11B in each embodiment, space occupation in the depth direction X can be avoided, effectively improving the space utilization of the refrigeration equipment in the depth direction X, and making the overall thickness of the refrigeration equipment thinner. Furthermore, by providing a process window 222B on the inner side plate 22B of the first air duct assembly 20B, the welding and processing of the return air pipe can be facilitated, as well as subsequent maintenance. Furthermore, the arrangement of the freezing air inlet 217B, the freezing return air inlet 221B, the refrigeration air inlet 312B, and the refrigeration return air inlet 321B makes the cold air distribution within the chamber more uniform.

[0260] In related technologies, the overall air duct structure of the refrigeration equipment is usually arranged on the back side wall of the refrigeration equipment in the depth direction X. This method will make the refrigeration equipment thicker for the same volume, and will occupy a lot of space in the depth direction X, which is not conducive to the ultra-thin design of the refrigeration equipment as a whole.

[0261] To address the problems in related technologies, as shown in Figures 20-25, this embodiment provides a refrigeration device, including a housing 10C, a refrigeration duct assembly 20C, and a pre-embedded refrigeration duct 30C. The housing 10C includes a refrigeration liner 12C for forming a refrigeration chamber 121C and a freezing liner 11C for forming a freezing chamber 111C, with the refrigeration chamber 121C located above the freezing chamber 111C. The refrigeration duct assembly 20C is connected to the side wall of the freezing liner 11C on the Y-side of its width. The refrigeration duct assembly 20C contains an installation chamber 211C, a first air inlet channel 216C, and a return air channel 212C. The first air inlet channel 216C is located on one side of the installation chamber 211C, and the return air channel 212C is located on the other side of the installation chamber 211C. A refrigeration circulation assembly 40C is disposed within... Inside the installation chamber 211C, the refrigeration cycle assembly 40C is used to cool and drive airflow; the refrigeration pre-embedded air duct 30C is pre-embedded in the side wall of the refrigeration inner liner 12C on one side in the width direction; the refrigeration pre-embedded air duct 30C has a second air inlet channel 32C; the freezing air duct assembly 20C also has a first cold air output port 213C, a second cold air output port 214C and a return air port 215C that are connected to the installation chamber 211C. The first cold air output port 213C is connected to the freezing chamber 111C through the first air inlet channel 216C, the second cold air output port 214C is connected to the refrigeration chamber 121C through the second air inlet channel 32C, the return air port 215C is connected to the freezing chamber 111C, and the refrigeration chamber 121C is connected to the return air port 215C through the return air channel 212C. When refrigeration equipment is cooling, it needs to transport cooled air to the refrigeration chamber 121C or the freezing chamber 111C through air ducts. Typically, the air duct is constructed entirely on the back panel in the depth direction (X) of the refrigeration equipment, making it difficult to optimize and control the overall thickness of the equipment. In this embodiment, by placing the freezing air duct assembly 20C and the second air inlet channel 32C on the side wall in the width direction (Y) of the refrigeration equipment, they do not occupy space in the depth direction (X), thereby enabling control over the overall thickness of the refrigeration equipment and significantly reducing its overall thickness.

[0262] Specifically, as shown in Figure 20, the cabinet 10C includes an inner liner structure, which comprises a freezer inner liner 11C and a refrigerator inner liner 12C. Both the freezer inner liner 11C and the refrigerator inner liner 12C define compartments for food storage, namely a refrigerator compartment 121C and a freezer compartment 111C. The distribution of these two compartments is the same as in conventional refrigeration equipment, both arranged vertically. That is, the refrigerator compartment 121C is located above the freezer compartment 111C. Specifically, multiple partitions are provided within the freezer compartment 111C and the refrigerator compartment 121C to divide the space of the freezer compartment 111C and the refrigerator compartment 121C into multiple layers for accommodating food. A second air inlet channel 32C is formed in the left or right side wall of the refrigerated inner liner 12C through the refrigerated pre-embedded air duct 30C. The second air inlet channel 32C can realize the transportation of cold air and realize the cooling of the internal environment of the refrigerated chamber 121C.

[0263] As shown in Figure 21, the refrigeration air duct assembly 20C is an external solid structure that connects to the left or right side wall of the refrigeration chamber 111C (left and right sides are referenced in the diagram) during installation, and can also connect to the side wall of the refrigeration equipment. Within the refrigeration air duct assembly 20C are formed the mounting chamber 211C, the first air inlet channel 216C, and the return air channel 212C, as shown in Figures 23 and 24. The mounting chamber 211C is located between the first air inlet channel 216C and the return air channel 212C. The refrigeration circulation assembly 40C is disposed within the mounting chamber 211C and is used to cool the flowing air and drive the air to circulate. A refrigerated pre-embedded air duct 30C is pre-embedded in the left or right side wall of the refrigerated inner liner 12C. The refrigerated pre-embedded air duct 30C forms a second air inlet channel 32C. The second air inlet channel 32C is used to connect the installation chamber 211C and the refrigerated chamber 121C to guide cold air into the refrigerated chamber 121C.

[0264] In a specific embodiment, the refrigerated pre-embedded air duct 30C is embedded in the side wall of the refrigerated inner liner 12C. That is, the refrigerated pre-embedded air duct 30C is pre-embedded into the side wall of the refrigerated inner liner 12C, and then foamed together, so that the refrigerated pre-embedded air duct 30C is located within the foam layer of the side wall of the refrigerated inner liner 12C, forming the second air inlet channel 32C. This method of forming, by using the shape of the refrigerated pre-embedded air duct 30C to construct the shape of the second air inlet channel 32C, makes the overall structure of the second air inlet channel 32C more stable and reduces the layout cost of the second air inlet channel 32C.

[0265] Specifically, the refrigeration cycle assembly 40C has a component for refrigeration and a drive component for realizing cold air circulation. The refrigeration component cools the air, and the drive component drives the air to circulate and remove heat from the freezer chamber 111C and the refrigerator chamber 121C during the flow, thereby realizing the refrigeration operation inside the chamber.

[0266] In a specific implementation, the refrigeration cycle assembly 40C is composed of components commonly used in the prior art, such as a compressor, condenser, evaporator 42C, expansion valve, and fan 41C. The overall refrigeration process involves the compressor compressing low-pressure, low-temperature refrigerant gas into high-pressure, high-temperature gas. The high-pressure, high-temperature refrigerant gas flows into the condenser, releases heat, and transforms into a liquid state. The liquid refrigerant enters the evaporator 42C through the expansion valve (or capillary tube), where the pressure drops sharply and the temperature decreases accordingly. The low-temperature, low-pressure refrigerant absorbs heat from the circulating air inside the refrigeration equipment within the evaporator 42C, and the refrigerant turns into gas again, thereby reducing the internal temperature of the refrigeration equipment. The fan 41C drives the air inside the refrigeration equipment to circulate, thereby maintaining the stability of the low temperature inside the refrigeration equipment.

[0267] Understandably, in this example, the side wall thickness of the refrigeration duct assembly 20C installed in the freezer inner liner 11C can be appropriately reduced, making it thinner than the side wall thickness of traditional refrigeration equipment. A second air intake channel 32C is directly formed within one side wall of the refrigerator inner liner 12C through a pre-embedded refrigeration duct 30C. This allows the side wall thickness of the refrigerator inner liner 12C to be comparable to that of traditional refrigeration equipment. This enables the refrigerator chamber 121C and the freezer chamber 111C to have a high space utilization rate in the width direction Y, avoiding the space occupied by the refrigeration duct assembly 20C and achieving full utilization of the refrigeration equipment's chamber space.

[0268] When the air inside the refrigeration equipment circulates, it is first cooled and driven by the refrigeration cycle component 40C. The cooled air enters the freezing chamber 111C and the refrigeration chamber 121C respectively through the first air inlet channel 216C and the second air inlet channel 32C, thereby cooling the internal space of the freezing chamber 111C and the refrigeration chamber 121C. Driven by the refrigeration cycle component 40C, the air flows and circulates, thereby achieving continuous circulation of the internal space of the refrigeration equipment.

[0269] In specific applications, the refrigeration duct assembly 20C has a first cold air output port 213C, a second cold air output port 214C, and a return air port 215C on the circumferential plate forming the installation chamber 211C. Both the first cold air output port 213C and the second cold air output port 214C are used to output cooled air for transportation. The transported air absorbs heat in the refrigeration chamber 111C or the refrigerator chamber 121C, and after absorbing heat, it enters the refrigeration cycle assembly 40C through the return air port 215C for recirculation and refrigeration, thus realizing the overall refrigeration cycle.

[0270] In conjunction with the above embodiments, a refrigerated return air vent 124C is provided at the bottom of the side wall of the refrigerated inner liner 12C on the side with the second air inlet channel 32C. The refrigerated return air vent 124C is located on the side away from the back panel of the refrigerated chamber 121C and is connected to the return air channel 212C. After absorbing heat in the refrigerated chamber 121C, the cold air needs to flow back to form a circulation in order to maintain a stable ambient temperature in the refrigerated chamber 121C. In this embodiment, by setting the refrigerated return air at the bottom and away from the back panel, the cold air distribution can be more uniform, improving the cooling efficiency and preventing localized low temperatures and frost formation.

[0271] Specifically, after passing through the refrigeration chamber 121C, the cold air gradually sinks and can be recirculated through the refrigeration return air vent 124C, thereby forming a cold air circulation and maintaining the stability of the internal temperature of the refrigeration chamber 121C.

[0272] In the specific setup, a baffle grille is installed inside the refrigerated return air vent 124C. The baffle grille can prevent large objects from entering the refrigerated return air vent 124C and blocking it, thereby improving the stability of the circulation loop.

[0273] In conjunction with the above embodiments, the bottom of the side wall of the inner refrigerated liner 12C, which has the second air inlet channel 32C, has an inclined portion 122C. The inclined portion 122C is inclined towards the interior of the refrigerated chamber 121C, forming an air-facing surface 123C on the inclined portion 122C. The refrigerated return air vent 124C is located on the air-facing surface 123C. After heat exchange, the heat in the refrigerated chamber 121C flows back through the refrigerated return air vent 124C. In this embodiment, the air-facing surface 123C effectively achieves air recirculation, facilitating rapid air recirculation and improving refrigeration efficiency.

[0274] Specifically, an inclined section 122C is integrally provided at the bottom of the side wall of the inner refrigerated liner 12C. The inclined section 122C is inclined towards the inside of the refrigerated chamber 121C, so that the inclined surface is set as the air-facing surface 123C. The refrigerated return air vent 124C is set on the air-facing surface 123C to realize direct air return, reduce energy consumption, and facilitate the return of air inside the refrigerated chamber 121C.

[0275] It is understandable that by setting the windward side 123C, the return air can be directly blown towards the windward side 123C, which can increase the air exchange flow rate, thereby improving the cooling efficiency and making the temperature distribution more even.

[0276] In conjunction with the above embodiments, at least one refrigerated air outlet 31C is provided on the side wall of the refrigerated inner liner 12C corresponding to the extended end of the second air inlet channel 32C. The refrigerated air outlet 31C is located near the back panel of the refrigerated chamber 121C and is situated in the upper region of the refrigerated chamber 121C. After entering the refrigerated chamber 121C, the cold air gradually sinks, absorbing heat in the process. This embodiment achieves uniform distribution of cold air by placing the refrigerated air outlet 31C in the upper region, effectively maintaining a stable temperature within the refrigerated chamber 121C.

[0277] Specifically, as shown in Figure 21, two refrigerated air inlets 31C are provided at the extended end of the second air inlet vent. Correspondingly, a connecting port is provided on the side wall of the refrigerated chamber 121C, connecting to the refrigerated air inlets 31C, thereby delivering cold air into the refrigerated chamber 121C. The two refrigerated air inlets 31C enable the delivery of cold air. Furthermore, by placing the refrigerated air inlets 31C near the back panel and the refrigerated return air inlet 124C on the side away from the back panel, the cold air can be fully distributed within the chamber space, preventing localized excessively low or high temperatures and improving the uniformity and stability of the temperature within the chamber.

[0278] It is understandable that the refrigeration chamber 121C has a lower demand for cold air compared to the freezing chamber 111C. In this embodiment, a refrigeration air outlet 31C is provided in the upper area of ​​the refrigeration chamber 121C so that the cold air can descend naturally, avoiding direct blowing on the food and causing it to freeze, which helps to distribute the cold air evenly.

[0279] In some embodiments, as shown in FIG25, a transition structure 50C is provided at one end of the refrigeration pre-embedded air duct 30C near the freezing chamber 111C. The transition structure 50C has a transition air duct 51C, which is used to connect the second cold air output port 214C and the second air inlet channel 32C.

[0280] Specifically, the adapter structure 50C is detachably connected to the refrigerated pre-embedded air duct 30C, and the transition air duct 51C in the adapter structure 50C is used to input cold air into the second air inlet channel 32C. The detachable connection of the adapter structure 50C allows for quick adjustment, ensuring that the cold air output from the second cold air output port 214C accurately enters the second air inlet channel 32C, improving the quality of cold air delivery and the ease of adjustment. In other words, during the connection process between the adapter structure 50C and the refrigerated pre-embedded air duct 30C, it is not necessary to move the entire refrigerated pre-embedded air duct 30C; only the position of the adapter structure 50C needs to be adjusted to achieve precise connection between the second cold air output port 214C and the second air inlet channel 32C, thereby greatly improving the convenience of the connection between the second air inlet channel 32C and the second cold air output port 214C.

[0281] The adapter structure 50C includes an integrally formed main body with a through hole inside. The through hole serves as a transition air duct 51C to enable the transmission of cold air.

[0282] In conjunction with the above embodiments, a damper assembly 60C is provided within the transition duct 51C. The damper assembly 60C is used to control the opening or closing of the second air inlet duct 32C. The damper assembly 60C is disposed within the through hole of the transition structure 50C, thereby enabling the opening or closing of the through hole.

[0283] Specifically, as shown in Figure 21, a damper assembly 60C is provided in the transition duct at the bottom of the second air inlet channel 32C. The damper assembly 60C is used to control the opening and closing of the second air inlet channel 32C, and can also control the air intake volume of the second air inlet channel 32C. The other end of the second air inlet channel 32C is connected to the refrigeration chamber 121C, thereby realizing the control of the entry of cold air. The damper assembly 60C adopts a mature damper assembly 60C structure, so the specific structure of the damper assembly 60C is not limited here.

[0284] In conjunction with the above embodiments, the refrigeration duct assembly 20C includes a main frame 21C, an inner side plate 22C, and a side plate 23C. The inner side plate 22C is fixedly disposed on one side of the main frame 21C, forming an installation chamber 211C and a return air channel 212C. The side plate 23C is fixedly disposed on one side edge of the main frame 21C, forming a first air inlet channel 216C. The refrigeration duct assembly 20C is disposed on the side wall of the refrigeration chamber 111C and can guide and circulate cold air. In this embodiment, the inner side plate 22C enables the solid frame structure inside the main frame 21C to enclose and construct different functional spaces. For example, the constructed installation chamber 211C is used for the installation of the refrigeration cycle assembly 40C, the constructed first air inlet channel 216C is connected to the freezing chamber 111C through the first cold air output port 213C to realize the guidance and delivery of cold air, and the constructed return air port 215C can realize the return flow of air after heat exchange in the freezing chamber 111C and the refrigeration chamber 121C to realize the overall air flow circulation refrigeration.

[0285] Specifically, the inner side plate 22C is located on the inner side surface of the main frame 21C, and the outer side surface of the main frame 21C is connected to the left wall of the freezer chamber 111C. An integral enclosure structure is formed on the main frame 21C, located in the middle of the main frame 21C and occupying most of its space. After the inner side plate 22C is connected to the main frame 21C, the space formed by the enclosure serves as the installation chamber 211C for the refrigeration cycle assembly 40C. An open return air port 215C is formed at the bottom of the enclosure. Return air from both the freezer chamber 111C and the refrigerator chamber 121C flows back through the return air port 215C and is recooled and returned to the circulation path by the refrigeration cycle assembly 40C. A gap exists between the side wall of the enclosure and the edge of the main frame 21C on that side, extending to the return air port 215C, thus forming a return air channel 212C to facilitate the return air recirculation within the refrigerator chamber 121C.

[0286] In the specific configuration, as shown in Figure 24, the main frame 21C has a first cold air output port 213C on the edge near the back plate of the freezer chamber 111C in the depth direction X. A recessed flow channel groove is formed on the side edge of this side. After being connected, the side plate 23C covers the flow channel groove to form a first air inlet channel 216C, which allows communication with the freezer chamber 111C. The main frame 21C has a second cold air output port 214C on the edge near the refrigerator chamber 121C. The second air inlet channel 32C communicates with the mounting chamber 211C through the second cold air output port 214C, thereby guiding cooling air into the refrigerator chamber 121C. In other words, by setting the first cold air port, the second cold air port, and the return air port 215C on the main frame 21C, the circulation of cooling air can be realized, maintaining the low temperature environment inside the refrigeration equipment. By setting them on the side wall, the overall thickness of the refrigeration equipment can be effectively reduced, achieving an ultra-thin structure that also accommodates large volume.

[0287] Understandably, the integral molding of the main frame 21C and the fixed connection of the inner side plate 22C and the side plate 23C facilitate the overall installation. Furthermore, this method integrates the first air inlet duct 216C, the return air duct 212C, and the installation chamber 211C, resulting in a more compact overall structure and better space utilization.

[0288] In conjunction with the above embodiments, a process window 222C is provided on the inner side plate 22C, which communicates with the installation chamber 211C. A sealing cover plate 24C is detachably connected to the process window 222C. When connecting the refrigeration cycle assembly 40C, the pipes on the evaporator 42C need to be welded. In this embodiment, the setting of the process window 222C facilitates welding and subsequent maintenance.

[0289] Specifically, the refrigeration cycle assembly 40C includes piping for refrigerant flow. In this embodiment, the refrigeration cycle assembly 40C is located on the side wall of the freezing chamber 111C. 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 222C, allowing welding to be performed through the process window 222C. Furthermore, subsequent maintenance can be performed quickly through the process window 222C, reducing later maintenance costs. The sealing cover plate 24C is detachably connected using screws or snap-fit ​​connections.

[0290] In the specific configuration, the inner side plate 22C has multiple partition support members 25C on its surface located in the freezing chamber 111C. These multiple partition support members 25C are evenly arranged in the vertical direction. As shown in Figure 23, two partition support members 25C are provided on the surface of the inner side plate 22C. One partition support member 25C is connected to the inner side plate 22C, and the other partition support member 25C is connected to the air vent cover plate 24C.

[0291] In conjunction with the aforementioned inner side plate 22C structure, in a specific embodiment, a refrigeration return air vent 221C is provided at the bottom of the inner side plate 22C. The refrigeration return air vent 221C is located away from the back plate of the refrigeration chamber 111C. The refrigeration return air vent 221C is connected to the return air port 215C, so as to realize the return air gas in the refrigeration chamber 111C to flow back to the refrigeration cycle assembly 40C.

[0292] Specifically, a grille structure is provided inside the refrigeration return air vent 221C. This grille structure can prevent items stored in the cavity from clogging the refrigeration return air vent 221C, thereby improving the stability of gas circulation. Furthermore, the location of the refrigeration return air vent 221C near the back panel improves the uniformity of cold air, ensuring a more even temperature distribution inside the refrigeration equipment.

[0293] It is understandable that the cold air gradually absorbs heat and sinks in the refrigeration chamber 111C. After its inner side plate 22C is connected to the main frame 21C, it itself serves as the inner wall of the refrigeration chamber 111C. The bottom of the inner side plate 22C is also the bottom of the refrigeration chamber 111C. By setting the refrigeration return air vent 221C at the bottom position, the refrigeration chamber 111C can be effectively cooled, and the stability of the return flow can also be improved.

[0294] In conjunction with the above embodiments, the first air inlet channel 216C is provided with multiple refrigeration air outlets 217C. The refrigeration air outlets 217C are located close to the back plate of the refrigeration chamber 111C, and the multiple refrigeration air outlets 217C are evenly spaced along the height direction Z of the refrigeration chamber 111C. Since there may be temperature differences in different areas within the refrigeration chamber 111C, this embodiment utilizes multiple refrigeration air outlets 217C to deliver cooled air to different levels of the refrigeration chamber 111C, achieving uniform airflow within the refrigeration chamber 111C, thereby improving the cooling quality.

[0295] Specifically, each refrigeration air inlet 217C is connected to the first air inlet channel 216C, and each partition has a corresponding refrigeration air inlet 217C. This method enables effective cooling of the space corresponding to each partition, improving cooling uniformity and achieving efficient cooling of each layer of the refrigeration chamber 111C. Furthermore, by placing the refrigeration air inlets 217C near the back panel and the refrigeration return air inlets 221C away from the back panel, the effective gas distribution area is increased, thereby achieving efficient cooling of the refrigeration chamber 111C and improving the uniformity of cold air distribution.

[0296] In a specific configuration, the refrigeration air outlet 217C can be formed on the wall of the refrigeration chamber 111C to deliver cold air. In a preferred embodiment, it is formed directly by connecting the main frame 21C and the inner side plate 22C. As shown in Figure 24, the main frame 21C has three cold air delivery slots formed on the wall of the side of the refrigeration equipment near the back panel in the depth direction X. After the side plate 23C is connected, it covers the cold air delivery slots to form the refrigeration air outlet 217C, thereby delivering cold air.

[0297] In some embodiments, the refrigeration cycle assembly 40C includes a fan 41C and an evaporator 42C. The fan 41C is located in the upper part of the mounting chamber 211C and above the evaporator 42C. The bottom of the evaporator 42C is located within the return air port 215C. The evaporator 42C can cool the circulating cold air, thereby achieving cooling of the entire air circulation loop. In this embodiment, by placing the fan 41C above the evaporator 42C and connecting the bottom of the evaporator 42C to the return air port 215C, effective cooling of the return air can be achieved, causing it to flow from the bottom of the evaporator 42C upwards, thus improving cooling efficiency.

[0298] Specifically, during the rotation of the fan 41C, its blades can drive the air flow in the area and create positive pressure at the first cold air outlet and the second air outlet to drive the air flow, while creating negative pressure on the side near the evaporator 42C to absorb the gas cooled by the evaporator 42C, thereby driving the entire cold air cycle.

[0299] In the specific implementation, as shown in Figures 21 and 24, the evaporator 42C has a spirally wound return pipe that connects to one end of the compressor. The return pipe requires welding during connection. In a specific configuration, the welding position of the return pipe is located within the area corresponding to process window 222C, thereby facilitating welding.

[0300] In conjunction with the above embodiments, the refrigeration cycle assembly 40C also includes an air guide shroud 43C, a fan 41C is installed inside the air guide shroud 43C, and the first cold air outlet and the second cold air outlet are both connected to the air guide shroud 43C.

[0301] Specifically, the air guide shroud 43C is connected to the main frame 21C by bolts, and a mounting groove is formed on one side of the main frame, which matches the shape of the air guide shroud 43C. The air guide shroud 43C has two outlet ends, which correspond to the first cold air outlet and the second cold air outlet, respectively, so that the fan 41C can drive the cold air to be output from the corresponding outlet ends during rotation.

[0302] In some embodiments, the sidewalls of the refrigeration duct assembly 20C and the second air inlet duct 32C are located on the same side of the housing 10C in the width direction Y. This same-side arrangement facilitates overall processing and installation, and also shortens the flow path of the second air inlet duct 32C, thereby improving refrigeration efficiency and reducing the loss of cold air.

[0303] It is understandable that during the cold air delivery process, the longer the delivery path, the greater the consumption and the greater the loss of cooling capacity. In this embodiment, by placing the sidewalls of the refrigeration duct assembly 20C and the second air inlet duct 32C on the same side, the flow path of the cold air can be shortened, thereby improving the overall cooling efficiency.

[0304] Through the above description of the embodiments, those skilled in the art can clearly understand that by arranging the air ducts on the side walls of the refrigeration chamber 121C and the freezing chamber 111C in each embodiment, space occupation in the depth direction X can be avoided, effectively improving the space utilization of the refrigeration equipment in the depth direction X, and making the overall thickness of the refrigeration equipment thinner. Furthermore, by providing a process window 222C on the inner side plate 22C of the freezing air duct assembly 20C, the welding and processing of the return air pipe can be facilitated, as well as subsequent maintenance. Furthermore, the arrangement of the freezing air inlet 217C, the freezing return air inlet 221C, the refrigeration air inlet 31C, and the refrigeration return air inlet 124C makes the cold air distribution within the chamber more uniform.

[0305] Finally, it should be noted that the above embodiments are only for illustrating the present invention and not for limiting 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.
