Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of household appliances, and in particular to a refrigerator. Background Art

[0002] The return air duct is an important part of the refrigerator. It can be used to connect the refrigerator compartment and the freezer compartment, so that the cold air in the refrigerator compartment can enter the freezer compartment through the return air duct, thereby realizing the cold air circulation inside the refrigerator.

[0003] The return air duct may be provided with a deodorizing device, thereby removing odors in the refrigerating chamber through the deodorizing device and improving the storage effect of the refrigerating chamber. However, the deodorizing device occupies a certain assembly space and has a poor deodorizing effect. Utility Model Content

[0004] The embodiment of the present application provides a refrigerator, which can solve the technical problems that a refrigerator deodorizing device occupies a certain assembly space and has a poor deodorizing effect.

[0005] In a first aspect, an embodiment of the present application provides a refrigerator, comprising:

[0006] The cabinet includes a freezer compartment and a refrigerator compartment;

[0007] a refrigeration system, disposed in the box, for providing cold air to the freezing chamber and the refrigerating chamber;

[0008] Air duct components, including:

[0009] An air duct structure is provided in the box body; the air duct structure is provided with a receiving cavity, and an air inlet and an air outlet communicated with the receiving cavity; the air inlet of the air duct structure is communicated with the refrigerating chamber, and the air outlet of the air duct structure is communicated with the freezing chamber;

[0010] The deodorizing component is arranged in the accommodating cavity and is at least used for deodorizing the cold air flowing through the accommodating cavity.

[0011] Since the cold air is deodorized before entering the freezer, the air inside the refrigerator can be kept fresh. By arranging a deodorizing component in the air duct structure, the odor in the refrigerator can be effectively removed. Integrating the deodorizing component into the accommodating cavity of the air duct structure avoids additional space occupation, optimizes the space utilization inside the refrigerator, and does not affect the layout of other functional components. Due to the design of the air duct structure, the cold air circulation between the refrigerator and the freezer is smoother, further improving the overall deodorization and ventilation efficiency of the refrigerator.

[0012] In some embodiments of the present application, the air duct structure is provided with a fixing member, and the air duct structure is connected to the deodorizing member via the fixing member.

[0013] The deodorizing element is firmly installed in the air duct structure through fixings, ensuring that the deodorizing element is always in a fixed position, maximizing its contact area with the cold air flowing through, and thus improving the deodorizing effect; the use of fixings enables the deodorizing element to be compactly integrated into the air duct structure, avoiding unnecessary waste of space and optimizing the spatial layout inside the refrigerator; the design of the fixings can simplify the installation and replacement process of the deodorizing element, reducing the difficulty and cost of maintenance.

[0014] In some embodiments of the present application, the deodorizing element abuts against the inner wall of the air duct structure;

[0015] The number of the fixing members is set to be multiple, and the multiple fixing members are arranged on the outside of the deodorizing member and abut against the edge of the deodorizing member;

[0016] The fixing member is arranged on the air duct structure. An abutment head is arranged on one end of the fixing member away from the air duct structure. The abutment head abuts against a surface of the deodorizing member away from the air duct structure.

[0017] Through the design of multiple fixings and abutments, the deodorizing element is ensured to be firmly installed in the air duct structure, maximizing its contact area with the cold air flowing through, thereby improving the deodorizing effect; multiple fixings provide multi-point support, making the deodorizing element more stable in the air duct structure, reducing vibration and displacement, and improving the stability of the structure; the design of the fixings and abutments enables the deodorizing element to be compactly integrated into the air duct structure, avoiding unnecessary space waste and optimizing the space layout inside the refrigerator; the design of the fixings and abutments can simplify the installation and replacement process of the deodorizing element, reducing the difficulty and cost of maintenance.

[0018] In some embodiments of the present application, from the air inlet to the air outlet, with a plane perpendicular to the extension direction of the accommodating cavity as a cross-section, the cross-sectional area of ​​the accommodating cavity gradually increases.

[0019] Odor molecules in the air can pass through the deodorizing element more quickly and fully, thereby improving deodorization efficiency. Furthermore, the change in the cross-sectional area of ​​the receiving cavity within the air duct structure can guide the airflow to form vortices around the deodorizing element, increasing the contact time and area between the air and the deodorizing material in the deodorizing element, further enhancing the deodorization effect. By optimizing the geometry of the air duct structure, the deodorizing element can be more effectively integrated without increasing the overall air duct volume, helping to save assembly space within the refrigerator. In some embodiments of the present application, within the receiving cavity, the deodorizing element is located near the air inlet, and the deodorizing element at least partially encloses the receiving cavity.

[0020] Placing the deodorizing element near the air inlet can perform deodorizing treatment as soon as the airflow enters the air duct structure, which helps to maximize the contact time between the deodorizing material and odor molecules and improve the deodorizing effect; by allowing the deodorizing element to close part of the accommodating cavity, the deodorizing function can be integrated without significantly increasing the volume of the air duct component, which helps to save assembly space inside the refrigerator; although the deodorizing element closes part of the accommodating cavity, by reasonably designing its shape and material, it can ensure smooth passage of airflow without significantly increasing airflow resistance, which helps to maintain the efficiency of cold air circulation.

[0021] In some embodiments of the present application, taking a plane perpendicular to the extension direction of the accommodating cavity as a cross-section, the cross-sectional area of ​​the deodorizing element is greater than or equal to 30% of the cross-sectional area of ​​the accommodating cavity and less than or equal to 70% of the cross-sectional area of ​​the accommodating cavity.

[0022] By covering 30% to 70% of the cross-sectional area, the deodorizing element can effectively process the passing airflow, ensuring that most odor molecules come into contact with the deodorizing material, thereby improving the deodorizing efficiency; retaining at least 30% of the open cross-sectional area ensures that the airflow can pass smoothly through the accommodating cavity, avoiding the increase in airflow resistance caused by excessive blockage, and helping to maintain the cold air circulation efficiency of the refrigerator; without significantly increasing the volume of the air duct component, the efficient deodorizing function is integrated, saving the assembly space inside the refrigerator.

[0023] In some embodiments of the present application, the air duct structure includes:

[0024] A base, the base being arranged on the box body and provided with the air inlet and the air outlet;

[0025] The air duct box is arranged on a side of the base facing away from the box body, and the air duct box and the base together form the accommodating cavity.

[0026] The design of the base provides a solid foundation, allowing the entire air duct structure to be firmly fixed on the refrigerator body, increasing the stability and durability of the structure; by setting the air duct box on one side of the base, the limited space inside the refrigerator can be effectively utilized, while providing sufficient accommodation space for the deodorizing component; the detachable design of the air duct box allows users to easily maintain and clean, or replace the deodorizing component, extending the service life of the equipment; by reasonably designing the position and size of the air inlet and outlet, the air flow path can be optimized, the flow resistance can be reduced, and the cooling air circulation efficiency can be improved.

[0027] In some embodiments of the present application, the base is provided with a plug-in slot, and the plug-in slot faces the air duct box;

[0028] The air duct box is provided with a connecting column, and the connecting column is inserted into the plug-in slot. The air duct box and the base are connected through the matching connecting column and the plug-in slot.

[0029] Through the design of the plug-in slot and connecting column, the air duct box and the base can be firmly connected, reducing the risk of loosening due to vibration or use; this plug-in design makes the assembly process simpler and faster, and at the same time, disassembly is more convenient when maintenance or replacement of the deodorizing parts is required. At the same time, due to the simplification of the assembly process, production efficiency can be improved and manufacturing costs can be reduced; this connection method allows for more flexibility in design and can be adjusted and adapted according to different refrigerator models and internal structures.

[0030] In some embodiments of the present application, the number of the connecting pillars is set to be multiple, and the multiple connecting pillars are arranged in sequence and spaced apart along the extension direction of the accommodating cavity.

[0031] The use and spaced arrangement of multiple connecting columns can effectively enhance the connection stability between the air duct box and the base, and reduce the impact of vibration and external force on the connection structure; the connecting columns are arranged in sequence along the extension direction of the accommodating cavity. This arrangement ensures uniform support of the air duct box over the entire length; through the distribution of multiple connecting columns, uniform distribution of load can be achieved, stress concentration at a single connection point can be reduced, and the service life of the structure can be extended; the design of multiple connecting columns can improve the assembly accuracy, ensure the close combination of the air duct box and the base, and reduce assembly errors; the spaced connecting columns allow more flexibility in design and can be adjusted and adapted according to different refrigerator models and internal structures.

[0032] In a second aspect, an embodiment of the present application provides a refrigerator, comprising:

[0033] The cabinet includes a freezer compartment and a refrigerator compartment;

[0034] a refrigeration system, disposed in the box, for providing cold air to the freezing chamber and the refrigerating chamber;

[0035] Air duct components, including:

[0036] An air duct structure is provided in the box;

[0037] The air duct structure is provided with an accommodating cavity, and the accommodating cavity is connected with the refrigerating chamber and the freezing chamber;

[0038] A deodorizing component is disposed in the accommodating cavity. When cold air flows from the refrigerating chamber through the accommodating cavity toward the freezing chamber, the deodorizing component is at least used to contact the cold air to deodorize the cold air.

Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0076] Reference Figure 1-Figure 5 and Figure 11 , the embodiment of the present application provides a refrigerator,

[0077] The cabinet 010 includes a freezing chamber 011 and a refrigerating chamber 012 .

[0078] It also includes a refrigeration system, which can be installed in the box body 010. The refrigeration system is used to provide cold air to the freezing chamber 011 and the refrigerating chamber 012.

[0079] It also includes an air duct assembly 100 , which includes an air duct structure 110 and is disposed in the box body 010 .

[0080] The air duct structure 110 is provided with a receiving cavity, and an air inlet 111 and an air outlet 112 communicating with the receiving cavity.

[0081] The air inlet 111 of the air duct structure 110 is in communication with the refrigerating chamber 012 , and the air outlet 112 of the air duct structure 110 is in communication with the freezing chamber 011 .

[0082] The air duct assembly 100 includes a deodorizing component 120 , which can be disposed in the accommodating cavity. The deodorizing component 120 is at least used to deodorize the cold air flowing through the accommodating cavity.

[0083] Since the cold air is deodorized before entering the freezer compartment 011, the air inside the refrigerator can be kept fresh. By arranging a deodorizing component 120 in the air duct structure, the odor in the refrigerator compartment 012 can be effectively removed. Integrating the deodorizing component 120 into the accommodating cavity of the air duct structure 110 avoids additional space occupation, optimizes the space utilization inside the refrigerator, and does not affect the layout of other functional components. Due to the design of the air duct structure 110, the cold air circulation between the refrigerator compartment 012 and the freezer compartment 011 is smoother, further improving the overall deodorization and ventilation efficiency of the refrigerator.

[0084] refer to Figure 9 In some possible implementations, the air duct structure 110 may be provided with a fixing member 130 .

[0085] The air duct structure 110 may be connected to the deodorizing element 120 via a fixing element 130 .

[0086] The deodorizing element 120 is firmly installed in the air duct structure by the fixing part 130, ensuring that the deodorizing element is always in a fixed position, maximizing its contact area with the cold air flowing through, and thus improving the deodorizing effect; the use of the fixing part 130 enables the deodorizing element 120 to be compactly integrated into the air duct structure, avoiding unnecessary waste of space and optimizing the spatial layout inside the refrigerator; the design of the fixing part 130 can simplify the installation and replacement process of the deodorizing element 120, reducing the difficulty and cost of maintenance.

[0087] refer to Figure 9-10 In some possible implementations, the deodorizing element 120 abuts against the inner wall of the air duct structure 110 .

[0088] The number of the fixing members 130 can be multiple, and the multiple fixing members 130 can be arranged on the outside of the deodorizing member 120 and abut against the edge of the deodorizing member 120 .

[0089] The fixing member 130 may be provided on the air duct structure 110 . An abutment head 131 may be provided on one end of the fixing member 130 facing away from the air duct structure 110 . The abutment head 131 may abut against the surface of the deodorizing member 120 facing away from the air duct structure 110 .

[0090] During use, the deodorizing element 120 is fixed in the space formed by the fixing element 130 , and the abutting portion 131 tightly fixes the deodorizing element 120 to the inner wall of the air duct structure 110 .

[0091] Through the design of multiple fixings 130 and abutments 131, the deodorizing element 120 is ensured to be firmly installed in the air duct structure, maximizing its contact area with the cold air flowing through, thereby improving the deodorizing effect; multiple fixings 130 provide multi-point support, making the deodorizing element 120 more stable in the air duct structure 110, reducing vibration and displacement, and improving the stability of the structure; the design of the fixings 130 and abutments 131 enables the deodorizing element 120 to be compactly integrated into the air duct structure, avoiding unnecessary waste of space and optimizing the spatial layout inside the refrigerator; the design of the fixings 130 and abutments 131 can simplify the installation and replacement process of the deodorizing element 120, reducing the difficulty and cost of maintenance.

[0092] refer to Figure 6-7 In some possible implementations, from the air inlet 111 to the air outlet 112 , with a plane perpendicular to the extension direction of the accommodating cavity as a cross-section, the cross-sectional area of ​​the accommodating cavity gradually increases.

[0093] The design of gradually increasing cross-sectional area can effectively utilize Bernoulli's principle to distribute the flow rate of gas in the accommodating cavity, which helps to distribute cold air more evenly and improve the air circulation efficiency of the refrigerating chamber 012 and the freezing chamber 011. The wind speed is relatively high at the air inlet 111, which is conducive to the rapid entry of odorous cold air into the accommodating cavity for filtration. As the cross-sectional area of ​​the accommodating cavity increases, the flow rate of cold air gradually decreases, avoiding the cold air impacting the air duct structure 110 and causing noise, while also allowing the cold air to have enough time to be purified by the deodorizing component 120.

[0094] In this way, odor molecules in the air can pass through the deodorizing element 120 more quickly and fully, thereby improving the deodorizing efficiency; at the same time, the change in the cross-sectional area of ​​the accommodating cavity in the air duct structure 110 can guide the airflow to form a vortex around the deodorizing element 120, increasing the contact time and contact area between the air and the deodorizing material in the deodorizing element 120, and further improving the deodorizing effect; by optimizing the geometric shape of the air duct structure 110, the deodorizing element 120 can be more effectively integrated without increasing the overall air duct volume, which helps to save assembly space inside the refrigerator.

[0095] refer to Figure 8In some possible implementations, from the air inlet 111 to the air outlet 112 , with a plane perpendicular to the extending direction of the accommodating cavity as a cross section, the cross-sectional height of the accommodating cavity gradually decreases.

[0096] Although the cross-sectional area increases, the height decreases. The shape of the air duct structure 110 is optimized within a limited space so that it can better adapt to the internal structure of the refrigerator and may help control the direction of the airflow. By gradually reducing the cross-sectional height, the direction of the airflow can be guided so that it can better flow to the freezer compartment 011, thereby improving the overall cooling and deodorization efficiency. By controlling the cross-sectional size and height of the accommodating cavity, the gas flow speed can be effectively controlled to an appropriate speed, thereby improving the deodorization efficiency while avoiding the airflow impacting the air duct structure 110, causing noise, and avoiding affecting the user experience.

[0097] According to the Bernoulli principle in fluid dynamics, the velocity of the fluid in the pipe is inversely proportional to the cross-sectional area. By designing the cross-sectional area of ​​the air duct structure 110 to gradually increase, the airflow velocity can be controlled and the airflow distribution can be optimized.

[0098] It is important to note that computational fluid dynamics (CFD) simulations can be used to analyze the impact of different cross-sectional designs on airflow patterns, thereby selecting the optimal design for the duct structure 110. Computational Fluid Dynamics (CFD) simulation is a technique that uses numerical analysis and algorithms to solve and analyze problems involving fluid flow. CFD simulations are widely used in engineering and science to study and predict fluid behavior, including the flow, heat transfer, mass transfer, and chemical reactions of gases and liquids under various conditions.

[0099] In some possible implementations, in the accommodation cavity, the deodorizing element 120 is close to the air inlet 111 , and the deodorizing element 120 closes at least a portion of the accommodation cavity.

[0100] The deodorizing element 120 is arranged at a position close to the air inlet 111, which is equivalent to the deodorizing element 120 being located at the initial position where the airflow enters the air duct. In this way, the deodorizing process can be started as soon as the airflow just enters the air duct structure 110; the deodorizing element 120 closes at least part of the accommodating cavity, which means that the deodorizing element 120 is not a structure that can cover or close part of the cross-section of the accommodating cavity of the air duct structure 110, and can force the airflow to pass through the deodorizing element 120, thereby improving the deodorizing efficiency.

[0101] Placing the deodorizing element 120 near the air inlet 111 can perform deodorizing treatment as soon as the airflow enters the air duct structure 120, which helps to maximize the contact time between the deodorizing material and the odor molecules and improve the deodorizing effect; by allowing the deodorizing element 120 to close part of the accommodating cavity, the deodorizing function can be integrated without significantly increasing the volume of the air duct assembly 100, which helps to save the assembly space inside the refrigerator; although the deodorizing element 120 closes part of the accommodating cavity, through the reasonable design of its shape and material, it can ensure smooth passage of airflow without significantly increasing the airflow resistance, which helps to maintain the efficiency of the cold air circulation.

[0102] In some possible implementations, taking a plane perpendicular to the extending direction of the accommodating cavity as a cross section, the cross-sectional area of ​​the deodorizing element 120 is greater than or equal to 30% and less than or equal to 70% of the cross-sectional area of ​​the accommodating cavity.

[0103] The cross-sectional area of ​​the deodorizing element 120 is designed to be greater than or equal to 30% of the cross-sectional area of ​​the accommodating cavity and less than or equal to 70% of the cross-sectional area of ​​the accommodating cavity, which means that the deodorizing element 120 occupies a certain proportion of the space in the air duct but does not completely block the airflow.

[0104] By covering 30% to 70% of the cross-sectional area, the deodorizing element 120 can effectively process the passing airflow, ensuring that most of the odor molecules come into contact with the deodorizing material, thereby improving the deodorizing efficiency; retaining at least 30% of the open cross-sectional area ensures that the airflow can smoothly pass through the accommodating cavity, avoiding the increase in airflow resistance caused by excessive blockage, and helping to maintain the cold air circulation efficiency of the refrigerator; without significantly increasing the volume of the air duct assembly 100, an efficient deodorizing function is integrated, saving the assembly space inside the refrigerator.

[0105] Exemplarily, the cross-sectional area of ​​the deodorizing element 120 may be within any range of 30%-40%, 40%-50%, 50%-60%, or 60%-70% of the cross-sectional area of ​​the accommodating cavity, to ensure that the deodorizing element 120 effectively purifies and deodorizes the gas flowing through the air duct structure 110 while ensuring that the gas can pass from the refrigerating chamber 012 to the freezing chamber 011.

[0106] refer to Figure 11 In some possible implementations, the air duct structure 110 includes a base 113 . The base 113 may be disposed on the box body 010 . The base 113 may be provided with an air inlet 111 and an air outlet 112 .

[0107] The air duct structure 110 further includes an air duct box 114 . The air duct box 114 can be arranged on a side of the base 113 facing away from the box body 010 . The air duct box 114 and the base 113 together form a receiving cavity.

[0108] The design of the base 113 provides a solid foundation, allowing the entire air duct structure 110 to be firmly fixed on the refrigerator body, increasing the stability and durability of the structure; by arranging the air duct box 114 on one side of the base 113, the limited space inside the refrigerator can be effectively utilized, while providing sufficient accommodation space for the deodorizing component 120; the detachable design of the air duct box 114 allows users to easily maintain and clean, or replace the deodorizing component 120, extending the service life of the equipment; by reasonably designing the position and size of the air inlet and outlet, the air flow path can be optimized, the flow resistance can be reduced, and the cooling air circulation efficiency can be improved.

[0109] refer to Figure 9 and Figure 12 In some possible implementations, the base 113 may be provided with a plug-in slot 1131 , and the plug-in slot 1131 faces the air duct box 114 .

[0110] The air duct box 114 may be provided with a connecting column 1141 , and the connecting column 1141 may be inserted into the plug-in slot 1131 . The air duct box 114 and the base 113 may be connected via the matching connecting column 1141 and the plug-in slot 1131 .

[0111] During use, the connecting column 1141 is inserted into the plug-in slot 1131 , so that the air duct box 114 and the base 113 can achieve a stable mechanical connection.

[0112] Through the design of the plug-in slot 1141 and the connecting column 1131, the air duct box and the base 114 113 can be firmly connected, reducing the risk of loosening due to vibration or use; this plug-in design makes the assembly process simpler and faster, and at the same time, when maintenance or replacement of the deodorizing component 120 is required, disassembly is also more convenient. At the same time, due to the simplification of the assembly process, production efficiency can be improved and manufacturing costs can be reduced; this connection method allows more flexibility in design and can be adjusted and adapted according to different refrigerator models and internal structures.

[0113] In some possible implementations, the number of the connecting pillars 1141 is set to be multiple.

[0114] The plurality of connecting pillars 1141 are sequentially spaced apart along the extending direction of the accommodating cavity.

[0115] The use and spaced arrangement of multiple connecting columns 1141 can effectively enhance the connection stability between the air duct box 114 and the base 113, and reduce the impact of vibration and external force on the connection structure; the connecting columns 1141 are arranged in sequence along the extension direction of the accommodating cavity. This arrangement ensures uniform support of the air duct box 114 over the entire length; through the distribution of multiple connecting columns 1141, uniform distribution of load can be achieved, stress concentration at a single connection point can be reduced, and the service life of the structure can be extended; the design of multiple connecting columns 1141 can improve the assembly accuracy, ensure the close combination of the air duct box 114 and the base 113, and reduce assembly errors; the spaced connecting columns 1141 allow more flexibility in design and can be adjusted and adapted according to different refrigerator models and internal structures.

[0116] refer to Figure 12 In some possible embodiments, the side of the air duct box 114 away from the base 113 has a reinforcing rib 1142. The provision of the reinforcing rib 1142 can enhance the structural strength of the air duct box 114 and prevent it from being deformed due to pressure or vibration during use.

[0117] In some possible embodiments, the base 113 and the air duct box 114 have corresponding screw holes, and the base 113 and the air duct box 114 are fixed together by screws. The screw connection provides a strong mechanical fixation, which can withstand vibration and temperature changes inside the refrigerator and maintain the stability of the air duct assembly 100. The screw connection also facilitates disassembly and reassembly, facilitating maintenance and replacement. When the deodorizing element 120 needs to be maintained or replaced, the base 113 and the air duct box 114 can be quickly and easily disassembled, saving time and labor costs.

[0118] refer to Figure 11 In some possible implementations, a sealing gasket 1111 is provided at the air inlet 111 .

[0119] Air inlet 111 is a key component of the return air duct. Cold air from the refrigerator compartment enters the duct through this duct. A sealing gasket 1111 is located at this duct and is typically made of a flexible material, such as rubber or silicone, to ensure a good seal. The primary function of sealing gasket 1111 is to prevent air leakage and ensure that cold air can circulate efficiently through duct structure 110.
