Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a refrigerator. Background Technology

[0002] Refrigerators are an indispensable household appliance in modern families, playing a vital role in food preservation and storage.

[0003] In related technologies, during the use of frost-free refrigerators, the food and associated contaminants stored inside undergo biochemical processes such as oxidation and decomposition, often resulting in unpleasant odors emanating from the refrigerator compartment due to prolonged food storage. Therefore, it is necessary to deodorize frost-free refrigerators. Activated carbon is commonly used in frost-free refrigerators to remove odors. A device containing activated carbon is fixed inside the refrigerator to deodorize it.

[0004] However, existing activated carbon devices suffer from poor performance. Utility Model Content

[0005] This application provides a refrigerator that enables convenient replacement of the deodorizing component, increases deodorizing time, reduces airflow resistance and dead zones, improves the effectiveness of the deodorizing component, and enhances the refrigerator's performance.

[0006] In a first aspect, embodiments of this application provide a refrigerator. The refrigerator includes a cabinet, an inner liner, a deodorizing component, and a flow guide.

[0007] The cabinet has a cavity. The inner liner is located within the cavity. The inner liner's structure forms a storage chamber. An air return vent is located on the inner liner.

[0008] The odor removal assembly is located at the return air vent. The odor removal assembly includes an odor removal box and an odor removal component. The odor removal box has an odor removal chamber. The odor removal box has a first opening and a second opening disposed opposite to each other. The odor removal chamber communicates with the return air vent through the first opening. The odor removal chamber communicates with a storage chamber through the second opening. The odor removal component is disposed within the odor removal chamber. The odor removal component and the odor removal box are detachably connected. A deflector is fixedly connected to the odor removal box.

[0009] The guide component and the deodorizing box define a guide channel; the guide channel connects the second opening and the storage cavity, and the guide channel is tortuous.

[0010] The above technical solution has the following advantages or beneficial effects: The refrigerator provided in this application embodiment, by placing the deodorizing component at the return air vent, can effectively guide the gas in the storage cavity into the deodorizing cavity for treatment. This design can continuously circulate the air in the storage cavity, thereby improving the deodorizing efficiency and keeping the air inside the refrigerator fresh.

[0011] By making the odor-eliminating component and the odor-eliminating box detachably connected, users can easily maintain and replace the odor-eliminating component. This design not only extends the lifespan of the odor-eliminating components but also reduces the difficulty and cost of maintenance for users, thus improving the user experience.

[0012] By placing the airflow guide near the second opening of the deodorizing box, the guide obstructs the airflow in the storage cavity from continuing along its original flow path, causing a first change in the airflow path. Furthermore, the tortuous design of the airflow guide channel lengthens the path of the airflow before entering the deodorizing cavity, further altering its flow path. This reduces the airflow velocity and increases the residence time of the reduced-velocity airflow within the deodorizing cavity, thereby increasing the contact time between the airflow and the deodorizing component. This helps to adsorb odor molecules in the gas and improves deodorization efficiency.

[0013] The airflow guide is used to direct airflow into the deodorizing chamber, ensuring that the airflow passes evenly through the deodorizing component. This design optimizes the airflow path and improves deodorizing efficiency.

[0014] In some embodiments of this application, the flow channel includes a first channel segment and a second channel segment.

[0015] The first channel section is connected to the storage chamber. The two ends of the second channel section are connected to the first channel section and the second opening, respectively, and the airflow direction of the second channel section forms an angle with the airflow direction of the first channel section.

[0016] The above technical solution has the following advantages or beneficial effects: by setting the extension direction of the first channel segment and the extension direction of the second channel segment to have an angle, the airflow path is changed. This design can effectively guide the airflow, so that it undergoes sufficient guidance and buffering before entering the deodorizing chamber, thereby improving the efficiency and effect of the airflow.

[0017] In some embodiments of this application, the flow guide includes a blocking portion and a flow guide portion. The blocking portion and the second opening are disposed opposite to each other. There is a gap between the blocking portion and the deodorizing box. The blocking portion extends along the height direction of the refrigerator. Along the direction perpendicular to the height of the refrigerator, the cross-sectional area of ​​the blocking portion is larger than the cross-sectional area of ​​the second opening.

[0018] The flow guide is located on the side of the shielding portion facing the deodorizing box, and at least a portion of the flow guide is connected to the deodorizing box. The flow guide includes multiple flow guide plates, which are spaced apart along the circumference of the second opening.

[0019] The shielding part, the flow guiding part, and the deodorizing box together form a flow guiding channel.

[0020] The above technical solution has the following advantages or beneficial effects: By setting the shielding part opposite to the second opening and setting the cross-sectional area of ​​the shielding part to be larger than the cross-sectional area of ​​the second opening, when the airflow in the storage cavity flows to the deodorizing component, the airflow is forced to diffuse under the action of the shielding part, and the airflow speed is reduced. The reduced airflow speed means that the airflow stays in the deodorizing cavity for a longer time, thereby increasing the contact time between the airflow and the deodorizing component. This increased contact time helps to improve the deodorizing efficiency.

[0021] Furthermore, the larger cross-sectional area of ​​the shielding section effectively alters the airflow path. By restricting the direct passage of airflow, the shielding section forces the airflow to diffuse before entering the second opening. This diffusion effect distributes the airflow over a larger area, avoiding direct airflow impact. Moreover, the larger area of ​​the shielding section acts as a barrier, preventing larger particles or foreign objects from directly entering the second opening. This physical barrier effectively blocks substances that could cause blockages, thus protecting the normal operation of the deodorizing component.

[0022] The baffle effectively guides airflow, directing it along a specific path before it enters the deodorizing chamber. This guidance helps optimize airflow and improves the contact efficiency between the airflow and the deodorizing components. Simultaneously, the baffle reduces airflow turbulence, ensuring a smooth entry of the airflow into the deodorizing chamber, thereby enhancing the deodorizing effect.

[0023] Because the deflectors are spaced apart circumferentially along the second opening, the airflow is disturbed and mixed as it passes through them. This mixing ensures that the airflow is fully mixed before entering the deodorization chamber, preventing it from concentrating in a small area and improving deodorization efficiency.

[0024] The airflow channel formed by the shielding part, the guide part and the deodorizing box together allows the airflow to be fully guided and diffused when entering the deodorizing chamber, increasing the contact time and contact area between the airflow and the deodorizing component, which helps to improve the deodorizing efficiency of the deodorizing component.

[0025] In some embodiments of this application, the deflector plate, in its orthographic projection from the deflector to the deodorizing box, does not cover the second opening.

[0026] The above technical solution has the following advantages or beneficial effects: the design of the deflector not covering the second opening allows airflow to enter the deodorizing chamber more directly, reducing resistance in the airflow path and improving airflow efficiency. Simultaneously, this resistance-reducing design allows more air to pass through in the same amount of time, thereby increasing airflow. Furthermore, this design allows for faster airflow, which helps to circulate and refresh the air inside the refrigerator more quickly, thus eliminating odors more rapidly.

[0027] In some embodiments of this application, the deflector plate, in its orthographic projection from the deflector to the deodorizing box, covers a portion of the second opening.

[0028] The above technical solution has the following advantages or beneficial effects: By covering the second opening with a baffle, the baffle can guide the airflow along a specific path, ensuring that the airflow fully contacts the deodorizing component through an optimized path, thereby improving the deodorization effect. At the same time, this design of the baffle covering the second opening can effectively control the airflow speed, avoiding excessively high airflow speeds from impacting the deodorizing component and other internal components, while ensuring effective air circulation.

[0029] In some embodiments of this application, the guide member further includes a fixing part. The fixing part includes a first end and a second end connected to each other. The first end is located in the deodorizing cavity and is connected to the inner wall of the deodorizing box; the second end extends out of the second opening and is connected to the shielding part.

[0030] The above technical solution has the following advantages or beneficial effects: The fixing part connects the inner wall of the deodorizing box and the shielding part, providing additional support and stability. This connection ensures that the deodorizing box and the shielding part remain in a fixed position during refrigerator use and will not move due to vibration or airflow. Furthermore, by connecting one end of the fixing part to the inner wall of the deodorizing box and the other end to the shielding part, it can be ensured that the shielding part is always in the optimal design position. This helps maintain the expected path and speed of airflow, thereby optimizing the deodorizing effect.

[0031] Furthermore, the design of the fixing unit simplifies the installation process of the odor-eliminating components and the shielding unit. By providing a clearly defined connection point, installers can more easily align and secure the various components, reducing installation time and complexity.

[0032] In some embodiments of this application, the deodorizing component includes a first cylinder, a second cylinder, and a deodorizing section.

[0033] The first cylinder has a first cavity. The first cavity is connected to a first opening.

[0034] The second cylinder is disposed within the first cavity. The second cylinder has a second cavity. The second cavity is connected to a second opening. A second through hole is provided on the peripheral wall of the second cylinder. The first cavity and the second cavity are connected through the second through hole.

[0035] The inner circumference of the first cylinder and the outer circumference of the second cylinder are spaced apart to form an annular cavity. The deodorizing section is located in the annular cavity.

[0036] The above technical solution has the following advantages or beneficial effects: the arrangement of the first and second cylinders improves the structural strength of the deodorizing component and reduces damage caused by vibration or impact. The cylinder part also includes a cylinder bottom plate. The first cylinder is sleeved on the outside of the second cylinder. The cylinder bottom plate connects the first and second cylinders. In this way, an annular cavity is formed between the inner circumference of the first cylinder, the cylinder bottom plate, and the outer circumference of the second cylinder.

[0037] The annular cavity design increases the volume of the odor removal section, thereby increasing the contact area between the airflow and the odor removal section. By increasing the volume of the odor removal section, the larger annular cavity means a greater adsorption capacity, allowing it to handle more odor molecules and improve overall odor removal efficiency. The larger volume also means that the odor removal section can remain effective for a longer period, reducing the frequency of replacement or regeneration.

[0038] The increased volume and contact area allow odor molecules in the airflow more opportunities to come into contact with and be adsorbed by the deodorizing unit. This design enables the unit to process more gas per unit time, improving its processing capacity.

[0039] Furthermore, the annular cavity design optimizes the airflow path and reduces airflow resistance. This optimization helps maintain smooth airflow, reduces turbulence, and thus improves deodorization efficiency.

[0040] In some embodiments of this application, the first cylinder and the deodorizing box are snap-fitted or screwed together.

[0041] The above technical solution has the following advantages or beneficial effects: The snap-fit ​​connection between the first cylinder and the deodorizing box makes the installation and disassembly process very simple, requiring no additional tools or complicated operations. Users can quickly remove the first cylinder from the deodorizing box for cleaning or replacement of the deodorizing part, and then quickly reinstall it. Furthermore, the design of the locking block and slot provides a secure connection, preventing loosening or detachment due to vibration or movement during refrigerator operation. The corresponding relationship between the locking block and slot ensures that connection can only be achieved in the correct position, reducing the possibility of misoperation.

[0042] The threaded connection enhances the connection strength between the first cylinder and the deodorizing box, ensuring that they will not easily loosen or detach during use. Users can easily disassemble and install the first cylinder by simple rotation, facilitating the replacement of the deodorizing unit.

[0043] In some embodiments of this application, the deodorizing component also includes a connecting rod.

[0044] The connecting rod is located in the deodorizing chamber. One end of the connecting rod is connected to the side wall of the deodorizing box near the second opening; the other end of the connecting rod extends away from the storage chamber.

[0045] There are multiple connecting rods, which are spaced apart along the circumference of the second opening to form a connecting section; the second cylinder is sleeved on the outside of the connecting section formed by the connecting rods.

[0046] The above technical solution has the following advantages or beneficial effects: the second cylinder is sleeved on the outside of the connecting section, meaning that the second cylinder is surrounded and supported by multiple connecting rods. This arrangement ensures that the second cylinder is uniformly supported throughout its entire circumference. Because the connecting rods provide circumferential support, the second cylinder can remain stable when subjected to external forces (such as vibration or airflow impact) and is not prone to tilting or displacement.

[0047] In some embodiments of this application, the deodorizing box includes a first box body and a second box body.

[0048] The first box is located at the return air vent and is connected to the inner liner; the first box has a first opening that is connected to the air duct.

[0049] The second box is located at the end of the first box near the storage cavity; the second box has a second opening, which is connected to the storage cavity.

[0050] The first and second boxes are detachably connected.

[0051] The above technical solution has the following advantages or beneficial effects: the detachable connection between the first and second housings allows users to easily clean, inspect, and replace them. This design reduces maintenance complexity and time, and lowers user maintenance costs.

[0052] The first chamber is located at the return air vent. It can be made of flexible plastic. The elasticity of the plastic allows it to fit the inner liner more easily, reducing gaps at the connection between the first chamber and the inner liner, thus improving airflow sealing. This helps prevent air leakage and improves deodorization efficiency. Furthermore, the flexible plastic can absorb some impact, reducing damage to the first chamber from collisions or vibrations. This improves the durability of the deodorizing box, especially with frequent door closing in the refrigerator. The second chamber can also be made of flexible plastic. This further improves the seal at the connection between the first and second chambers, preventing gas leakage from the deodorization chamber.

[0053] Secondly, embodiments of this application provide a refrigerator, which includes a cabinet, an inner liner, an odor-removing component, and an air-guiding component. The cabinet has a cavity. The inner liner is located within the cavity. The inner liner is constructed to form a storage cavity. An air return vent is provided on the inner liner.

[0054] The deodorizing assembly is located at the return air vent. The deodorizing assembly includes a deodorizing box and a deodorizing element. The deodorizing box has a deodorizing chamber. The deodorizing chamber communicates with the return air vent through a first opening. The deodorizing chamber communicates with a storage chamber through a second opening. The deodorizing element is used to deodorize the airflow. A flow guide is configured to guide the gas in the storage chamber to the deodorizing chamber. The flow guide is configured to form a flow channel. The flow channel has an air outlet port and an air inlet port. The air outlet port communicates with the second opening. The air inlet port communicates with the storage chamber. The air inlet port and the air outlet port are offset.

[0055] The above technical solution has the following advantages or beneficial effects: by making the odor-removing component and the odor-removing box detachably connected, users can easily maintain and replace the odor-removing component. This design not only extends the service life of the odor-removing components but also reduces the user's maintenance difficulty and cost, thus improving the user experience.

[0056] By staggering the air inlet and outlet ports of the air guide channel, the airflow must travel a longer or more complex path when entering and leaving the air guide channel. In this way, by optimizing the airflow path, reducing the airflow velocity, increasing the contact time between the airflow and the deodorizing component, reducing airflow turbulence and unnecessary resistance, and improving the deodorizing efficiency of the deodorizing component.

[0083] To make the objectives, implementation methods and advantages of this application clearer, the exemplary implementation methods of this application will be clearly and completely described below with reference to the accompanying drawings of the exemplary embodiments of this application. Obviously, the described exemplary embodiments are only some embodiments of this application, and not all embodiments.

[0084] It should be noted that the brief descriptions of terms in this application are only for the convenience of understanding the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise stated, these terms should be understood in their ordinary and common meaning.

[0085] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover but not exclusively include, for example, a product or device that includes a series of components is not necessarily limited to those that are explicitly listed, but may include other components that are not explicitly listed or that are inherent to such product or device.

[0086] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0087] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0088] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0089] In related technologies, the activated carbon deodorizing device in a frost-free refrigerator is fixedly installed inside the refrigerator. Although activated carbon has a certain adsorption capacity, it will reach saturation after a period of use and lose its adsorption capacity. This requires users to replace the activated carbon in the device periodically. When replacing the activated carbon, users need to disassemble certain parts of the refrigerator to replace the device. This is complicated for users. In addition, frequent disassembly of the refrigerator structure may affect the overall performance of the refrigerator; for example, the refrigerator's sealing may be affected, thus affecting the refrigerator's cooling efficiency and energy consumption.

[0090] In summary, the activated carbon deodorizing devices in refrigerators in related technologies have the problem of poor performance.

[0091] In view of this, this application provides a refrigerator. The refrigerator includes a cabinet, an inner liner, a deodorizing component, and a flow guide. The cabinet has a cavity. The inner liner is disposed in the cavity. The inner liner is structured to form a storage cavity. A return air vent is provided on the inner liner. The deodorizing component is disposed at the return air vent. The deodorizing component includes a deodorizing box and a deodorizing element. The deodorizing box has a deodorizing cavity. The deodorizing box has a first opening and a second opening disposed opposite to each other. The deodorizing cavity communicates with the return air vent through the first opening. The deodorizing cavity communicates with the storage cavity through the second opening. The deodorizing element is disposed in the deodorizing cavity. The deodorizing element and the deodorizing box are detachably connected. The flow guide is fixedly connected to the deodorizing box. Wherein, the flow guide and the deodorizing box define a flow channel; the flow channel communicates with the second opening and the storage cavity, and the flow channel is tortuous.

[0092] The refrigerator provided in this application embodiment effectively guides the gas in the storage cavity into the deodorization chamber for treatment by placing the deodorizing component at the return air vent. This design continuously circulates the air in the storage cavity, thereby improving deodorization efficiency and keeping the air inside the refrigerator fresh.

[0093] By making the odor-eliminating component and the odor-eliminating box detachably connected, users can easily maintain and replace the odor-eliminating component. This design not only extends the lifespan of the odor-eliminating components but also reduces the difficulty and cost of maintenance for users, thus improving the user experience.

[0094] By placing the airflow guide near the second opening of the deodorizing box, the guide obstructs the airflow in the storage cavity from continuing along its original flow path, causing a first change in the airflow path. Furthermore, the tortuous design of the airflow guide channel lengthens the path of the airflow before entering the deodorizing cavity, further altering its flow path. This reduces the airflow velocity and increases the residence time of the reduced-velocity airflow within the deodorizing cavity, thereby increasing the contact time between the airflow and the deodorizing component. This helps to adsorb odor molecules in the gas and improves deodorization efficiency.

[0095] The airflow guide is used to direct airflow into the deodorizing chamber, reducing airflow resistance and dead zones, and ensuring that airflow passes evenly through the deodorizing component. This design optimizes the airflow path and improves deodorization efficiency.

[0096] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0097] This application provides a refrigerator. (Ref.) Figures 1 to 11 As shown, the refrigerator includes a cabinet 100. The cabinet 100 has a cavity. The height of the refrigerator is shown in the figure. Figure 1 The direction indicated by Z. The width of the refrigerator is referenced. Figure 1 The direction indicated by X in the middle. The depth reference for the refrigerator. Figure 1 The direction shown in Y.

[0098] The refrigerator also includes an inner liner 200. The inner liner 200 is disposed within the cavity. The inner liner 200 is constructed to form a storage cavity. An air return vent is provided on the inner liner 200.

[0099] Reference Figures 2 to 4 As shown, the refrigerator also includes a deodorizing component 300. The deodorizing component 300 is located at the air return vent. This allows the deodorizing component 300 to directly process the airflow exiting the storage compartment. This placement enables the deodorizing component 300 to efficiently remove odors and maintain fresh air inside the refrigerator.

[0100] The return air vent is located on the side wall of the inner liner 200.

[0101] Reference Figures 5 to 8 As shown, the deodorizing assembly 300 includes a deodorizing box 310. The deodorizing box 310 has a deodorizing cavity. The deodorizing cavity is used to connect the storage cavity and the return air vent. The deodorizing box 310 has a first opening 313 and a second opening 314 disposed opposite to each other. The deodorizing cavity is connected to the return air vent through the first opening 313, and the deodorizing cavity is connected to the storage cavity through the second opening 314.

[0102] Reference Figures 9 to 10 As shown, the deodorizing assembly 300 includes a deodorizing component 320. The deodorizing component 320 is used for deodorization. The deodorizing component 320 is disposed in the deodorizing chamber. The deodorizing component 320 and the deodorizing box 310 are detachably connected. The detachable design of the deodorizing component 320 and the deodorizing box 310 allows users to easily maintain and replace them. This design not only extends the service life of the deodorizing assembly 300 but also reduces the user's maintenance difficulty and cost.

[0103] Reference Figure 7 and Figure 11 As shown, the refrigerator also includes a deflector 330. The deflector 330 is fixedly connected to the deodorizing box 310.

[0104] The guide member 330 and the deodorizing box 310 define a guide channel 340; the guide channel 340 connects the second opening 314 and the storage cavity, and the guide channel 340 is tortuous.

[0105] The flow guide 330 is positioned close to the second opening 314. The flow guide 330 obstructs the airflow in the storage cavity from continuing along its original flow path, reducing the airflow velocity. At the same time, the flow guide 330 and the deodorizing box 310 define a flow channel 340. The tortuous flow channel 340 lengthens the path of the airflow before it enters the deodorizing cavity, thereby reducing the airflow velocity and increasing the residence time of the reduced-velocity airflow in the deodorizing cavity. This increases the contact time between the airflow and the deodorizing component 320, which helps to adsorb odor molecules in the gas and improves the deodorization efficiency.

[0106] The flow guide 330 is configured to guide the gas in the storage chamber to the deodorization chamber. The flow guide 330 is used to guide the airflow into the deodorization chamber, reducing airflow resistance and dead zones, and ensuring that the airflow passes evenly through the deodorization component 320.

[0107] In some embodiments, the flow channel 340 may be a right-angle bend.

[0108] In other embodiments, the flow channel 340 may be curved.

[0109] The airflow channel 340 has an air outlet port and an air inlet port. The air outlet port communicates with the second opening 314. The air inlet port communicates with the storage cavity. The air inlet port and the air outlet port are staggered. By staggering the air inlet port and the air outlet port of the airflow channel 340, the airflow must take a longer or more complex path when entering and leaving the airflow channel 340. In this way, by optimizing the airflow path, reducing the airflow velocity, increasing the contact time between the airflow and the deodorizing component 320, reducing airflow turbulence and unnecessary resistance, and improving the deodorizing efficiency of the deodorizing component 300.

[0110] The refrigerator also includes an air duct structure. This structure forms an air duct. The air duct connects to a return air vent. The return air vent allows airflow between the storage compartment and the air duct. This design helps maintain temperature uniformity within the storage compartment and promotes air circulation, thereby reducing condensation and frost.

[0111] For example, refer to Figure 12 As shown, during refrigerator use, the airflow in the storage cavity flows to the deodorizing component 300. First, the airflow comes into contact with the guide vane 330. The guide vane 330 obstructs the airflow from continuing along its original path. The airflow diffuses at the guide vane 330, and its flow path makes its first turn at the guide vane 330, flowing along the extension direction of the guide vane 330. The guide vane 330 increases the airflow path and slows down the airflow velocity.

[0112] Subsequently, the decelerated airflow enters the guide channel 340. Upon reaching the guide channel 340, the airflow path undergoes a second bend due to the staggered inlet and outlet ports. The airflow then flows along the tortuous guide channel 340 through the second opening 314 into the deodorization chamber. The airflow then comes into contact with the deodorizing element 320 located within the deodorization chamber, which adsorbs odors from the airflow.

[0113] Finally, the deodorized airflow flows into the air duct through the first opening 313. This step completes the airflow circulation, allowing the treated air to re-enter the refrigerator's circulation system.

[0114] In this way, the airflow path changes twice as the airflow approaches the guide member 330 and enters the guide channel 340 defined by the guide member 330 and the deodorizing box 310. This reduces the airflow velocity, increases the contact time between the airflow and the deodorizing member, reduces airflow turbulence and unnecessary resistance, and improves the deodorizing efficiency of the deodorizing component.

[0115] As one feasible implementation, the flow channel 340 includes a first channel segment 341 and a second channel segment 342. The first channel segment 341 communicates with the storage cavity. The two ends of the second channel segment 342 are respectively connected to the first channel segment 341 and the second opening 314. The airflow direction of the second channel segment 342 forms an angle with the airflow direction of the first channel segment 341. By setting the extension direction of the first channel segment 341 and the extension direction of the second channel segment 342 at an angle, the airflow path is changed. This design can effectively guide the airflow, allowing it to undergo sufficient guidance and buffering before entering the deodorizing cavity, thereby improving the efficiency and effect of the airflow.

[0116] In some embodiments, the angle between the extending direction of the first channel segment 341 and the extending direction of the second channel segment 342 is 90°.

[0117] As one feasible implementation method, refer to Figure 5 , Figure 13 , Figure 14 As shown, the flow guide 330 includes a blocking part 331 and a flow guide part 332.

[0118] The shielding portion 331 and the second opening 314 are disposed opposite to each other, and there is a gap between the shielding portion 331 and the deodorizing box 310. The shielding portion 331 extends along the height direction of the refrigerator. Along the direction perpendicular to the height of the refrigerator, the cross-sectional area of ​​the shielding portion 331 is larger than the cross-sectional area of ​​the second opening 314.

[0119] A flow guide 332 is disposed on the side of the shielding portion 331 facing the deodorizing box 310. At least a portion of the flow guide 332 is connected to the deodorizing box 310. The flow guide 332 includes a plurality of flow guide plates. The plurality of flow guide plates are spaced apart along the circumference of the second opening 314.

[0120] The shielding part 331, the flow guiding part 332 and the deodorizing box 310 together form the flow guiding channel 340.

[0121] For example, by configuring the shielding portion 331 to be opposite to the second opening 314, and by configuring the cross-sectional area of ​​the shielding portion 331 to be larger than the cross-sectional area of ​​the second opening 314, when the airflow in the storage cavity flows to the deodorizing component 300, the airflow is forced to diffuse under the action of the shielding portion 331, and the airflow speed is reduced. The reduced airflow speed means that the airflow stays in the deodorizing cavity for a longer time after entering it, thereby increasing the contact time between the airflow and the deodorizing component 320. This increased contact time helps to improve the deodorizing efficiency.

[0122] The larger cross-sectional area of ​​the shielding portion 331 effectively alters the airflow path. By restricting the direct passage of airflow, the shielding portion 331 forces the airflow to diffuse before entering the second opening. This diffusion effect distributes the airflow over a larger area, avoiding direct airflow impact. Furthermore, the larger area of ​​the shielding portion 331 acts as a barrier, preventing larger particles or foreign objects from directly entering the second opening 314. This physical barrier effectively blocks substances that may cause blockages, thereby protecting the normal operation of the deodorizing component 300.

[0123] Conversely, when the cross-sectional area of ​​the blocking portion 331 is smaller than that of the second opening 314, the smaller blocking portion 331 may not effectively slow down the airflow velocity, causing the airflow to pass through the second opening 314 rapidly. This rapid flow may reduce the contact time between the airflow and the deodorizing component 320, thereby reducing the deodorization efficiency. Furthermore, when the cross-sectional area of ​​the blocking portion 331 is smaller than that of the second opening 314, the airflow may not diffuse sufficiently before entering the second opening 314, causing the airflow to concentrate in a small area. This concentrated flow may lead to overuse of some parts of the deodorizing component 320 while other parts are underutilized. Additionally, the smaller blocking portion 331 may not effectively prevent larger particles or foreign objects from entering the second opening 314, increasing the risk of clogging the deodorizing component 300. This may result in a decrease in deodorization performance and require more frequent maintenance and cleaning.

[0124] For example, the shielding part 331 may be a baffle.

[0125] Furthermore, the baffle effectively guides the airflow, directing it along a specific path before it enters the deodorizing chamber. This guidance helps optimize airflow and improves the contact efficiency between the airflow and the deodorizing component 320. Simultaneously, the baffle reduces airflow turbulence, ensuring a smooth entry of the airflow into the deodorizing chamber, thereby enhancing the deodorizing effect.

[0126] Since the baffles are spaced apart circumferentially along the second opening, they guide the airflow into the deodorizing chamber, reducing airflow resistance and dead zones, and ensuring that the airflow passes evenly through the deodorizing component 320. This design optimizes the airflow path and improves deodorizing efficiency. Simultaneously, the airflow is disturbed and mixed as it passes through these baffles. This mixing ensures that the airflow is fully mixed before entering the deodorizing chamber, preventing airflow from concentrating in a small area and improving deodorizing efficiency.

[0127] The guide channel 340 formed by the shielding part 331, the guide part 332 and the deodorizing box 310 allows the airflow to be fully guided and diffused when entering the deodorizing chamber, promoting airflow mixing and increasing the contact time and contact area between the airflow and the deodorizing component 320, which helps to improve the deodorizing efficiency of the deodorizing assembly 300.

[0128] As one possible implementation, the deflector plate, in its orthographic projection in the direction from the deflector 330 to the deodorizing box 310, does not cover the second opening 314.

[0129] The design of the deflector not covering the second opening 314 allows airflow to enter the deodorizing chamber more directly, reducing resistance in the airflow path and improving airflow efficiency. Simultaneously, this resistance-reducing design allows more air to pass through in the same amount of time, thus increasing airflow volume. Furthermore, this design allows for faster airflow, contributing to quicker circulation and renewal of the air inside the refrigerator, thereby eliminating odors more rapidly.

[0130] As one possible implementation, the deflector plate, in the orthographic projection from the deflector 330 to the deodorizing box 310, covers a portion of the second opening 314.

[0131] By covering a portion of the second opening 314 with a baffle, the baffle guides the airflow along a specific path, ensuring that the airflow makes full contact with the deodorizing component through an optimized path, thereby improving the deodorization effect. At the same time, this design of the baffle covering the second opening effectively controls the airflow velocity, preventing excessively high airflow velocities from impacting the deodorizing component 320 and other internal components, while ensuring effective air circulation.

[0132] As one feasible implementation, the guide member 330 also includes a fixing part 360. The fixing part 360 includes a first end and a second end connected to each other. The first end is located in the deodorizing cavity and is connected to the inner wall of the deodorizing box 310; the second end extends out of the second opening 314 and is connected to the shielding part 331.

[0133] The fixing part 360 connects the inner wall of the deodorizing box 310 and the shielding part 331, providing additional support and stability. This connection ensures that the deodorizing box 310 and the shielding part 331 remain in a fixed position during refrigerator use and will not move due to vibration or airflow. Furthermore, by connecting one end of the fixing part 360 to the inner wall of the deodorizing box 310 and the other end to the shielding part 331, it ensures that the shielding part 331 is always in its optimal design position. This helps maintain the expected path and speed of airflow, thereby optimizing the deodorization effect.

[0134] Furthermore, the design of the fixing part 360 simplifies the installation process of the odor-removing component 300 and the shielding part 331. By providing a clear connection point, installers can more easily align and secure the various components, reducing installation time and complexity.

[0135] As one feasible implementation method, refer to Figure 4 , Figures 8 to 10As shown, the deodorizing box 310 includes a first box body 311. The first box body 311 is located at the return air vent and is connected to the inner liner 200. A first opening 313 is provided on the first box body 311. The first opening 313 communicates with the air duct. By directly connecting the first box body 311 to the inner liner 200, it is ensured that the deodorizing box 310 remains stable during refrigerator operation and is not easily displaced due to vibration or movement. The stable connection between the first box body 311 and the inner liner 200 reduces the gap between the deodorizing box 310 and the inner liner 200, thereby reducing airflow leakage. This helps ensure that all airflow passes through the deodorizing component 320, improving deodorization efficiency.

[0136] The deodorizing box 310 also includes a second box body 312. The second box body 312 is located at the end of the first box body 311 near the storage cavity. The second box body 312 is provided with a second opening 314. The second opening 314 communicates with the storage cavity.

[0137] The first housing 311 and the second housing 312 are detachably connected. This detachable connection allows users to easily clean, inspect, and replace the parts. This design reduces maintenance complexity and time, lowering maintenance costs for users.

[0138] In some embodiments, the outer periphery of the first housing 311 is provided with a protrusion. The inner periphery of the second housing 312 is provided with a recess. The protrusion and the recess are arranged opposite to each other. The first housing 311 and the second housing 312 are connected by the protrusion and the recess to achieve a detachable connection between the first housing 311 and the second housing 312.

[0139] In other embodiments, the outer periphery of the first housing 311 is provided with a recess. The inner periphery of the second housing 312 is provided with a protrusion. The protrusion and the recess are arranged opposite to each other. The first housing 311 and the second housing 312 are connected by the protrusion and the recess to achieve a detachable connection between the first housing 311 and the second housing 312.

[0140] It is understandable that there can be multiple protrusions and depressions to improve the connection stability of the first box 311 and the second box 312.

[0141] For example, the first box 311 is located at the return air vent. The first box 311 can be made of elastic plastic. The elastic plastic is flexible, making it easier to fit the inner liner 200, reducing gaps at the connection between the first box 311 and the inner liner 200, thereby improving airflow sealing. This helps prevent airflow leakage and improves deodorization efficiency. Furthermore, the elastic plastic can absorb some impact force, reducing damage to the first box 311 caused by collisions or vibrations. Given the frequent closing of the refrigerator door, this improves the durability of the deodorizing box 310.

[0142] For example, the second housing 312 can also be made of elastic plastic. This improves the sealing at the connection between the first housing 311 and the second housing 312, preventing gas leakage from the deodorizing chamber.

[0143] For example, refer to Figure 12 As shown, during refrigerator use, the airflow in the storage cavity first enters the deodorization cavity through the second opening 314, ensuring that the air in the storage cavity can be introduced into the deodorization component 300 for treatment. The airflow entering the deodorization cavity then flows through the deodorization chamber of the deodorization component 320. The deodorized airflow then flows into the air duct through the first opening 313. This step completes the airflow circulation, allowing the treated air to re-enter the refrigerator's circulation system. The airflow direction is shown in the figure. Figure 12 The direction indicated by the black arrow in the middle.

[0144] It is understandable that the odor-removing box 310 can be a cube, a cuboid, or a cylinder.

[0145] As one feasible implementation method, refer to Figure 7 , Figures 8 to 11 As shown, the deodorizing component 320 includes a first cylindrical body 321. The first cylindrical body 321 has a first cavity. The first cavity is connected to a first opening 313. A first through hole 323 is provided on the peripheral wall of the first cylindrical body 321, and the first cavity is connected to the first opening 313 through the first through hole 323.

[0146] The deodorizing component also includes a second cylindrical body 322. The second cylindrical body 322 is disposed within the first cavity. The second cylindrical body 322 has a second cavity, which communicates with a second opening 314. A second through hole 324 is provided on the peripheral wall of the second cylindrical body 322. The first cavity and the second cavity communicate through the second through hole 324.

[0147] There is a gap between the inner circumference of the first cylinder 321 and the outer circumference of the second cylinder 322, forming an annular cavity.

[0148] The arrangement of the first cylinder 321 and the second cylinder 322 improves the structural strength of the deodorizing component 320 and reduces damage caused by vibration or impact.

[0149] For example, refer to Figure 10 As shown, the cylindrical body also includes a cylindrical body bottom plate 321b. The first cylindrical body 321 is sleeved on the outside of the second cylindrical body 322. The cylindrical body bottom plate 321b connects the first cylindrical body 321 and the second cylindrical body 322. In this way, an annular cavity is formed between the inner circumference of the first cylindrical body 321 and the outer circumference of the cylindrical body bottom plate 321b and the second cylindrical body 322.

[0150] The deodorizing section is located in the annular cavity.

[0151] Compared to related technologies, where activated carbon deodorization devices have a square structure with a square cavity containing activated carbon, airflow may encounter more resistance and dead zones within the square cavity, leading to insufficient utilization of activated carbon in certain areas. In the embodiments provided in this application, the annular cavity design increases the volume of the deodorization section, thereby increasing the contact area between the airflow and the deodorization section. Increasing the volume of the deodorization section, the larger annular cavity means a larger adsorption capacity, enabling the processing of more odor molecules and improving overall deodorization efficiency. The larger volume and material quantity also mean that the deodorization section can remain effective for a longer period, reducing the frequency of replacement or regeneration.

[0152] The increased volume and contact area allow odor molecules in the airflow more opportunities to come into contact with and be adsorbed by the deodorizing unit. This design enables the processing of more gas per unit time, improving the processing capacity of the deodorizing component 300.

[0153] Furthermore, the annular cavity design optimizes the airflow path and reduces airflow resistance. This optimization helps maintain smooth airflow, reduces turbulence, and thus improves deodorization efficiency.

[0154] For example, the first cylinder 321, the cylinder base plate 321b, and the second cylinder 322 are integrally molded parts. This integral molding reduces the complexity of manufacturing and assembling the first cylinder 321, the second cylinder 322, and the cylinder base plate 321b. This not only reduces production time but also reduces labor and equipment costs. The integral molding eliminates potential weaknesses at the joints of the first cylinder 321, the second cylinder 322, and the cylinder base plate 321b, improving the overall structural strength and durability. This makes the cylinder section more resistant to mechanical stress and vibration during use.

[0155] For example, the second cavity is connected to the annular cavity via a second through-hole 324. The annular cavity is connected to the air duct via a first through-hole 323. By precisely positioning the first through-hole 323 and the second through-hole 324, airflow can directly enter the annular cavity from the second cavity and then from the annular cavity into the air duct. This direct connection reduces eddies and dead zones in the airflow path, ensuring smooth airflow. Reducing eddies and dead zones contributes to uniform airflow distribution, ensuring that airflow passes evenly through the deodorizing material, thus improving deodorization efficiency. Furthermore, by designing the size of the first through-hole 323 and the second through-hole 324, the airflow velocity can be precisely controlled. Smaller through-holes can increase the airflow velocity, while larger through-holes can slow down the airflow velocity. This control capability allows for optimization of the contact time between the airflow and the deodorizing part, thereby improving the deodorization effect.

[0156] As one possible implementation, the first cylinder 321 and the deodorizing box 310 are snap-fitted or screwed together.

[0157] In some embodiments, refer to Figure 9 and Figure 10 As shown, the deodorizing box 310 is a rectangular box. The first cylindrical body 321 and the deodorizing box 310 are snapped together. At least two locking blocks 321a are provided on the outer periphery of the first cylindrical body 321. At least two locking slots 312a are provided on the inner periphery of the deodorizing box 310. The at least two locking blocks 321a and the at least two locking slots 312a are arranged in a one-to-one correspondence to ensure the stability and accuracy of the connection between the first cylindrical body 321 and the deodorizing box 310. When the locking block 321a is located within the locking slot 312a, the first cylindrical body 321 is in a connected state. When the locking block 321a disengages from the locking slot 312a, the first cylindrical body 321 is in a disengaged state.

[0158] The snap-fit ​​connection between the first cylinder 321 and the deodorizing box 310 makes installation and disassembly extremely simple, requiring no additional tools or complicated operations. Users can quickly remove the first cylinder 321 from the deodorizing box 310 for cleaning or replacement of the deodorizing unit, and then quickly reinstall it. Furthermore, the design of the locking block 321a and the locking slot 312a provides a secure connection, preventing loosening or detachment due to vibration or movement during refrigerator operation. The corresponding relationship between the locking block 321a and the locking slot 312a ensures that connection is only achieved in the correct position, reducing the possibility of misoperation.

[0159] In other embodiments, the deodorizing box 310 is a cylindrical box. The first cylindrical body 321 and the deodorizing box 310 are screwed together. The inner circumference of the deodorizing box 310 is provided with a first thread. The outer circumference of the first cylindrical body 321 is provided with a second thread. The deodorizing box 310 and the first cylindrical body 321 are threaded together by the first thread and the second thread.

[0160] The threaded connection provides a strong mechanical bond, ensuring that the first cylinder 321 and the deodorizing box 310 will not easily loosen or fall off during use. Users can easily disassemble and install the first cylinder 321 by simple rotation, facilitating the replacement of the deodorizing unit.

[0161] As one feasible implementation method, refer to Figure 7 and Figure 10 As shown, the deodorizing assembly 300 also includes a connecting rod 350. The connecting rod 350 is located in the deodorizing chamber. One end of the connecting rod 350 is connected to the side wall of the deodorizing box 310 near the second opening 314. The other end of the connecting rod 350 extends away from the storage chamber.

[0162] There are multiple connecting rods 350. Along the circumference of the second opening 314, multiple connecting rods 350 are spaced apart to form a connecting section; the second cylinder 322 is sleeved on the outside of the connecting section formed by the connecting rods 350.

[0163] For example, the connecting rod 350 is located in the deodorizing chamber, with one end connected to the side wall of the deodorizing box 310 near the storage chamber, and the other end extending away from the storage chamber, i.e., near the air duct. Multiple connecting rods 350 are spaced circumferentially along the second opening 314, forming a uniform support structure. These connecting rods 350 form a connecting section around the second opening 314, providing multiple support points. This multi-point support structure can effectively distribute and bear the load from the second cylinder 322.

[0164] The second cylinder 322 is fitted onto the outside of the connecting section, meaning it is surrounded and supported by multiple connecting rods 350. This arrangement ensures that the second cylinder 322 is uniformly supported throughout its circumference. Because the connecting rods 350 provide circumferential support, the second cylinder 322 remains stable when subjected to external forces (such as vibration or airflow impact) and is not prone to tilting or displacement.

[0165] For example, refer to Figure 15 As shown, the refrigerator also includes a shelf assembly 400. The shelf assembly 400 includes a shelf holder body and a filter 420. Support ribs are provided on the inner wall of the inner liner 200. The support ribs are used to support the shelf holder body 410.

[0166] The shelf body 410 is constructed to form a water collection tank. The interior of the shelf body 410 has protruding ribs for supporting the filter screen 420. The filter screen 420 is used to hold food ingredients.

[0167] The drip tray collects condensation or dripping liquid from food, preventing liquid from spreading inside the refrigerator and keeping it clean and dry. The 420 filter design allows air to circulate freely around food, which helps maintain freshness and prevents spoilage caused by moisture buildup.

[0168] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them.
