Description

Technical Field

[0001] The embodiments of the present application relate to the technology of storage equipment. In particular, it relates to a storage box. Background Art

[0002] With the development of technology and the improvement of living standards, people have higher requirements for the storage period of items. For most items, low temperature is a relatively preferred storage condition.

[0003] In the related art, a refrigerator is provided inside a storage cabinet to maintain a low temperature. The refrigerator can absorb the heat in the space where it is located to maintain the low temperature inside the storage cabinet.

[0004] However, during the operation of the refrigerator, the items near the refrigerator are affected by the refrigerator, and their temperatures are different from those of the items in other positions, which is not conducive to the temperature uniformity inside the storage cabinet. Utility Model Content

[0005] Some embodiments of the present application provide a storage box, which is provided with two independent channels. The rear cover can separate the storage cavity from the refrigeration component. The direct distance between the refrigeration component and the storage cavity is relatively small. The rear cover can reduce the direct influence of the refrigeration component on the inside of the storage cavity, thereby avoiding the influence of the refrigeration component on the temperature uniformity of the storage cavity and being beneficial to the storage of items.

[0006] Some embodiments of the present application provide a storage box, including:

[0007] A box body, inside which a storage cavity is defined;

[0008] An air flow circulation component, having:

[0009] A first channel, the input port of the first channel communicating with the storage cavity;

[0010] A second channel, the input port of the second channel communicating with the storage cavity;

[0011] A mixed air channel, having:

[0012] A mixed air channel input port, communicating with the output ports of the first channel and the second channel;

[0013] A mixed air channel output port, communicating with the storage cavity;

[0014] The air flow circulation component includes:

[0015] A rear cover, on the side of the rear cover facing away from the storage cavity, the first channel is formed, and the rear cover separates the storage cavity from the first channel;

[0016] a fan, located in at least one of the air mixing channel, the first channel, and the second channel, for driving air flow;

[0017] A refrigeration component is located in the first channel, and the rear cover is used to separate the refrigeration component and the storage cavity.

[0018] Some embodiments of the present application provide a storage box, which has a storage cavity and an air circulation component connected to the storage cavity. The air circulation component receives the airflow from the storage cavity through a first channel and a second channel respectively, drives the airflow through a fan, forms the first channel on the rear side of the rear cover, and arranges a refrigeration component in the first channel so that the rear cover separates the refrigeration component and the storage cavity.

[0019] In this way, the back cover can separate the storage cavity and the refrigeration component. The direct distance between the refrigeration component and the storage cavity is small. The back cover can reduce the direct impact of the refrigeration component on the inside of the storage cavity, thereby avoiding the refrigeration component affecting the temperature uniformity of the storage cavity, which is conducive to the storage of items.

[0020] In some embodiments of the present application, a return air cavity is formed on a side of the rear cover facing the storage cavity, and the return air cavity is communicated with the storage cavity;

[0021] There is a first communication position between the return air chamber and the storage chamber, and there is a second communication position between the first channel and the storage chamber;

[0022] Along the flow direction of the airflow, the first communication position is located upstream of the second communication position.

[0023] With this arrangement, the return air chamber filled with gas can serve as air isolation, effectively isolating the refrigeration component from the storage chamber, preventing the refrigeration component from directly affecting the temperature in the storage chamber, and helping to ensure temperature uniformity in the storage chamber.

[0024] In some embodiments of the present application, the fan includes:

[0025] The first fan is located in the first channel and is used to drive the air flow in the first channel to flow to the air mixing channel.

[0026] With such an arrangement, the first fan can drive the air flow in the first channel, thereby forming an air circulation.

[0027] In some embodiments of the present application, the first fan is a centrifugal fan;

[0028] The rear cover has a mounting section for mounting the first fan, and the mounting section is extended along the Archimedean spiral.

[0029] With this configuration, the centrifugal fan can provide stable airflow at a larger air volume; the installation section can improve the centrifugal wind pressure and efficiency.

[0030] In some embodiments of the present application, the airflow circulation component further includes:

[0031] a front cover, located on a side of the rear cover facing the storage cavity, with the air mixing channel formed between the front cover and the rear cover;

[0032] a decorative plate located on a side of the front cover facing the storage cavity, wherein at least a portion of the second channel is formed between the decorative plate and the front cover;

[0033] A back plate is located on a side of the rear cover facing away from the storage cavity, and the first channel is formed between the back plate and the rear cover.

[0034] With this arrangement, the decorative panel, front cover, rear cover and back plate can be stacked and connected in sequence to form the aforementioned first channel, second channel and air mixing channel, thereby forming an air circulation between the storage cavity and the air circulation component.

[0035] In some embodiments of the present application, the back cover further has:

[0036] An auxiliary channel is formed at the lower portion of the rear cover and passes through the lower portion of the front cover. An input end of the auxiliary channel is connected to the storage chamber and the first channel, and the return air chamber is connected to the middle position of the auxiliary channel.

[0037] With this arrangement, the auxiliary channel can realize the filling of the return air cavity. The return air cavity filled with gas can serve as air isolation, effectively isolating the refrigeration component from the storage cavity, preventing the refrigeration component from directly affecting the temperature in the storage cavity, and helping to ensure the uniformity of the temperature in the storage cavity.

[0038] In some embodiments of the present application, the airflow circulation assembly includes a first guide structure, and the first guide structure includes:

[0039] a first guide plate;

[0040] a second guide plate, forming together with the first guide plate a mixing guide channel, wherein the mixing guide channel is connected to the upstream of the air mixing channel;

[0041] a third guide plate, located between the first guide plate and the second guide plate, wherein a first guide channel is formed between the third guide plate and the first guide plate, wherein the first guide channel is connected to the downstream of the first channel and to the upstream of the mixing guide channel;

[0042] A second guide channel is formed between the third guide plate and the second guide plate, and the second guide channel is connected to the downstream of the second channel and the upstream of the mixing guide channel;

[0043] The airflow velocity received by the mixing guide channel is respectively smaller than the airflow velocity output by the first guide channel and the airflow velocity output by the second guide channel.

[0044] With this arrangement, by forming guide channels with different flow rates, the airflow contracts downstream of the first guide channel and the second guide channel. When the airflow passes through this position, the airflow velocity increases and the pressure decreases, forming a Venturi effect, thereby forming a one-way flow.

[0045] In some embodiments of the present application, the airflow circulation assembly includes a second guide structure, and the second guide structure includes:

[0046] a first deflection plate, located at the output port of the first guide structure, wherein the surface extension direction of the first deflection plate intersects with the flow direction of the air mixing channel;

[0047] There are multiple first deflection plates, and the multiple first deflection plates are arranged at intervals in the air mixing channel;

[0048] A first direction-changing channel is formed between two adjacent first direction-changing plates, and a flow direction of the first direction-changing channel intersects with a flow direction of the air mixing channel;

[0049] The first deflection plate is configured to allow the airflow to flow in the first deflection channel and change the Reynolds number of the airflow until the flow state of the airflow becomes turbulent.

[0050] With this arrangement, the flow state of the airflow is turbulent, and the airflow output from the first channel and the airflow output from the second channel flow in an irregular and chaotic manner. The two airflows are strongly mixed, so that the second guide structure can enhance the mixing degree of the airflow, ensure the uniformity and stability of the airflow, and thus improve the uniformity of the storage environment.

[0051] In some embodiments of the present application, the second guide structure further includes:

[0052] A second deflection plate is located at the output port of the first deflection plate. There are multiple second deflection plates, and the multiple second deflection plates are arranged at intervals in the air mixing channel.

[0053] A second direction-changing channel is formed between two adjacent second direction-changing plates, and the flow direction of the second direction-changing channel is the same as the flow direction of the air mixing channel;

[0054] The second deflection plate is configured to allow the airflow to flow in the second deflection channel and change the Reynolds number of the airflow until the flow state of the airflow changes from turbulent flow to laminar flow.

[0055] In this way, if the flow state of the airflow is laminar, it means that the second changing channel can receive the airflow output by the first changing channel and flow in a parallel path to improve the flow consistency of the airflow in the mixed air channel, thereby ensuring the uniformity and stability of the airflow output to improve the uniformity of the storage environment.

[0056] In some embodiments of the present application, the airflow circulation assembly includes a third guide structure, and the third guide structure includes:

[0057] a first outlet section, forming a first outlet channel, the first outlet channel being connected to the outlet of the air mixing channel, the outlet of the first outlet channel having a larger aperture than the outlet of the air mixing channel;

[0058] The second outlet section is formed with a second outlet channel, the second outlet channel is connected to the outlet of the air mixing channel, and the aperture of the outlet of the second outlet channel is larger than the aperture of the outlet of the air mixing channel; wherein,

[0059] The aperture of the output port of the first outlet channel is different from the aperture of the output port of the second outlet channel.

[0060] With such a configuration, the storage box can adjust the positions of the first outlet channel and the second outlet channel according to the stored items to match items with different needs, thereby achieving adaptive and soft air outlet. BRIEF DESCRIPTION OF THE DRAWINGS

[0092] In order to make the purpose, implementation mode and advantages of the present application clearer, the exemplary implementation mode of the present application will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present application. Obviously, the described exemplary embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0093] It should be noted that the brief descriptions of terms in this application are only for the purpose of facilitating the understanding of the embodiments described below, and are not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their ordinary and usual meanings.

[0095] In the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application.

[0096] The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, unless otherwise stated, the meaning of "a plurality" is two or more.

[0097] In the description of the present application, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0098] Next, some embodiments of the present application will be described clearly and completely with reference to the accompanying drawings in some embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0099] In the related art, as disclosed in a low-temperature and high-humidity plus variable-frequency high-voltage electrostatic hybrid thawing device of Chinese Patent CN215571546U, it is used for thawing and preserving food. The thawing device includes a cabinet body, in which a thawing cavity and a unit installation cavity are provided. In the unit installation cavity, an evaporator, a condenser, a compressor, and a centrifugal fan are sequentially connected. An air outlet duct is provided on the left side of the thawing cavity, and a plurality of second through holes communicating with the unit installation cavity are provided on the side wall of the air outlet duct, and the second through holes are connected to the evaporator. However, in the above solution, the evaporator is directly communicated with the thawing cavity through the second through holes. The evaporator will reduce the air temperature, and the area near the second through holes is affected more, with a lower temperature, and the temperature in the cavity is not uniform, which is not conducive to the thawing or preservation of food.

[0100] In view of this, some embodiments of the present application provide a storage box, which has a storage cavity and an air flow circulation component communicated with the storage cavity. The air flow circulation component receives the air flow in the storage cavity through a first channel and a second channel respectively, drives the air flow to flow through a fan, forms the first channel at the rear side of the rear cover, and arranges a refrigeration component in the first channel, so that the rear cover separates the refrigeration component from the storage cavity.

[0101] In this way, the rear cover can reduce the direct influence of the refrigeration component on the interior of the storage cavity, thereby avoiding the influence of the refrigeration component on the temperature uniformity of the storage cavity, which is beneficial to the storage of items.

[0102] In the present application, it should be understood that the meanings of the related terms are as follows:

[0103] Ventilation volume: The volume of air passing through a certain cross-section per unit time.

[0104] Venturi effect: According to the fluid continuity equation and Bernoulli equation, when a fluid flows through a converging duct, due to the increase in the flow velocity of the fluid, its kinetic energy increases, while the pressure energy decreases accordingly. This means that in the narrow part of the converging duct, the fluid has the highest velocity and the lowest pressure.

[0105] Preset range: Adapt to the storage conditions of the stored items.

[0106] Laminar flow: It refers to the flow of fluid particles along parallel paths or layers without mixing with each other.

[0107] Turbulent flow: It refers to the flow of fluid particles in an irregular and chaotic manner, with strong mixing and vortices occurring inside the fluid.

[0108] Refer to Figure 1 , in some embodiments, the storage box 10 includes a box body 100. The box body 100 is the main structure of the storage box 10, and a space for storing items, that is, a storage cavity 101, is formed inside. In this way, the box body 100 can provide a closed storage space, facilitating the control of the internal environmental conditions.

[0109] In some embodiments, the storage box 10 includes an air flow circulation component 200, and the air flow circulation component 200 is used to adjust the air flow in the storage cavity 101, including but not limited to adjusting the flow velocity, ventilation volume, temperature, humidity, oxygen content, etc. of the air flow.

[0110] Refer to Figure 2 , in some embodiments, the air flow circulation component 200 is located outside the storage box 10, that is, the air flow circulation component 200 does not occupy the storage cavity 101, so as to facilitate the storage of more items.

[0111] Refer to Figure 1, in some embodiments, the air flow circulation component 200 is located inside the storage box 10, that is, the air flow circulation component 200 is located inside the storage box 10, which facilitates the air flow circulation component 200 to receive the air flow output from the storage cavity 101 and also facilitates the air flow circulation component 200 to output the air flow from the storage cavity 101.

[0112] In some embodiments, the air flow circulation component 200 has a first channel 201 for conveying air flow. The first channel 201 has an input port and an output port. The side where the air flow enters the first channel 201 is the input port, and the side where the air flow exits the first channel 201 is the output port. The input port of the first channel 201 communicates with the storage cavity 101, that is, the first channel 201 is connected to the storage cavity 101, and the first channel 201 can receive the air flow in the storage cavity 101.

[0113] In some embodiments, the air flow circulation component 200 has a second channel 202 for conveying air flow. The second channel 202 also has an input port and an output port, which will not be elaborated here. The input port of the second channel 202 communicates with the storage cavity 101, that is, the second channel 202 is connected to the storage cavity 101, and the second channel 202 can receive the air flow in the storage cavity 101.

[0114] In some embodiments, the air flow circulation component 200 has a mixing channel 203 with a mixing channel input port 203a and a mixing channel output port 203b. The mixing channel input port 203a is simultaneously connected to the output port of the first channel 201 and the output port of the second channel 202, and the mixing channel output port 203b is connected to the storage cavity 101. The mixing channel 203 is used to receive the air flows input from the first channel 201 and the second channel 202 and output the mixed air flow to the storage cavity 101 after mixing.

[0115] It can be understood that the first channel 201 and the second channel 202 respectively form an air flow. In this way, the two air flows enter the mixing channel 203 and are mixed in the mixing channel 203. Therefore, the physical parameters of the air flow output from the mixing channel 203 are between the physical parameters of the air flow in the first channel 201 and the physical parameters of the air flow in the second channel 202.

[0116] That is to say, the physical parameters of the air flow output by the air flow circulation component 200 are between the physical parameters of the air flow received by the air flow circulation component 200 and the physical parameters of the air flow inside the air flow circulation component 200.

[0117] In some embodiments, the air flow circulation component 200 includes a fan 250 for driving the air flow to flow.

[0118] It can be understood that the blower 250 can be an axial blower, and the air flow is axially flowed along the axial direction of the blower blades under the action of the axial blower. The blower 250 can also be a centrifugal blower, and the air flow is radially flowed along the radial direction of the blower blades under the action of the centrifugal blower. The blower 250 can also be a mixed-flow blower, and under the action of the mixed-flow blower, part of the air flow is axially flowed along the axial direction of the blower blades, and the other part is radially flowed along the radial direction of the blower blades.

[0119] In some embodiments, the blower 250 is located in at least one of the first channel 201, the second channel 202, and the air mixing channel 203, so that the air flow output from the storage cavity 101 can enter the air flow circulation assembly 200, and the air flow output from the air flow circulation assembly 200 can flow back to the storage cavity 101, forming an air flow circulation of storage cavity 101 - air flow circulation assembly 200 - storage cavity 101.

[0120] Referring to Figure 2 , in some embodiments, the air flow circulation assembly 200 includes an adjustment assembly 20 for changing the physical parameters of the air flow passing through. The physical parameters include but are not limited to the aforementioned temperature, humidity, oxygen content, etc.

[0121] In some embodiments, the adjustment assembly 20 is located in at least one of the first channel 201 and the second channel 202, that is, the adjustment assembly 20 can adjust the air flow that has not entered the air mixing channel 203, such as raising the air flow temperature, lowering the air flow temperature, raising the air flow humidity, lowering the air flow humidity, raising the air flow oxygen content, lowering the air flow oxygen content, etc.

[0122] It should be noted that for the first channel 201 and the second channel 202 referred to in some embodiments of the present application, their shapes, positions, compositions, etc. can all be selected according to actual situations. Exemplarily, the second channel 202 can include a plurality of connected parts, and the two parts are not adjacent in position but the air flow can pass through.

[0123] Referring to Figure 1 , in some embodiments, when the physical parameter includes temperature, the adjustment assembly 20 includes a refrigeration assembly 300. The refrigeration assembly 300 is located in the first channel 201 for lowering the temperature of the air flow passing through the first channel 201, so that the air flow output from the air mixing channel 203 has a lower temperature. The type of the refrigeration assembly 300 can be selected according to actual situations.

[0124] In some embodiments, the refrigeration assembly 300 can be a vapor compression refrigeration system. When the refrigeration assembly 300 is a vapor compression refrigeration system, the vapor compression refrigeration system includes an evaporator 310, and the evaporator 310 can vaporize the moisture in the air flow passing through, and then absorb heat to complete refrigeration while lowering the air flow humidity.

[0125] Referring to Figure 1, in some embodiments, a first channel 201 is formed on the side of the rear cover 230 facing away from the storage cavity 101, and the rear cover 230 separates the storage cavity 101 from the first channel 201;

[0126] The air flow process is as follows:

[0127] First, the air flow in the storage cavity 101 enters the first channel 201 under the action of the fan 250, and the refrigeration component 300 can cool the air flow passing through the first channel 201. Then, the cooled air flow enters the mixing channel 203 through the input port 203a of the mixing channel. Then, after being mixed with the air flow output from the second channel 202, the air flow enters the storage cavity 101 through the output port 203b of the mixing channel, forming an air flow cycle.

[0128] It can be understood that during the above air flow process, although the storage cavity 101 is communicated with the first channel 201, the rear cover 230 can separate the storage cavity 101 from the refrigeration component 300. In this way, the direct distance between the refrigeration component 300 and the storage cavity 101 is relatively small, and the air flow enters the mixing channel 203 through the first channel 201, and the air flow cannot flow back. Therefore, the rear cover 230 can reduce the direct influence of the refrigeration component 300 on the inside of the storage cavity 101, and further avoid the refrigeration component 300 from affecting the temperature uniformity of the storage cavity 101, which is beneficial to the storage of items.

[0129] Refer to Figure 2 , in some embodiments, a return air cavity 231 is formed on the side of the rear cover 230 facing the storage cavity 101, and the return air cavity 231 can be filled with gas. The return air cavity 231 filled with gas can be used as an air isolation, effectively isolating the refrigeration component 300 from the storage cavity 101, avoiding the refrigeration component 300 from directly affecting the temperature in the storage cavity 101, and helping to ensure the temperature uniformity in the storage cavity 101.

[0130] The return air cavity 231 is communicated with the storage cavity 101, and there is a first communication position 231a between the return air cavity 231 and the storage cavity 101. The air flow can enter the return air cavity 231 from the storage cavity 101 through the first communication position 231a to ensure that the air flow can enter and fill the return air cavity 231.

[0131] The first channel 201 and the storage cavity 101 have a second communication position 231b, and along the air flow direction, the first communication position 231a is located upstream of the second communication position 231b.

[0132] The air flow can enter the storage cavity 101 from the first channel 201 through the second communication position 231b, ensuring that the air flow can first enter the return air cavity 231 through the first communication position 231a, and after filling the return air cavity 231, enter the first channel 201 through the second communication position 231b to ensure the air flow cycle.

[0133] Reference Figure 2 In some embodiments, the fan 250 includes a first fan 251, which is located in the first channel 201 and is used to drive the airflow in the first channel 201 to flow toward the air mixing channel 203. In this way, the first fan 251 can drive the airflow in the first channel 201 to form an air circulation.

[0134] In some embodiments, the first fan 251 is a centrifugal fan, which is located in the first channel 201. The centrifugal fan has the characteristics of high efficiency and high pressure head, and can provide stable airflow at a large air volume, which helps to maintain a stable airflow in the first channel 201 and ensure that the airflow can be effectively transported and discharged.

[0135] Reference Figure 3 In some embodiments, the rear cover 230 has a mounting section 232 for mounting the first fan 251. The mounting section 232 extends along an Archimedean spiral. Generating a structural profile using a curve equation can improve centrifugal wind pressure and efficiency.

[0136] Reference Figure 4 In some embodiments, when the physical parameter includes temperature, the adjustment assembly 20 includes a heating assembly 400. The heating assembly 400 is located within the second channel 202 and is configured to increase the temperature of the airflow flowing through the second channel 202, thereby causing the air mixing channel 203 to output a higher temperature airflow. The type of heating assembly 400 can be selected based on actual circumstances.

[0137] Reference Figure 4 In some embodiments, when the physical parameter includes humidity, the adjustment component 20 includes a humidification component 500. The humidification component 500 can increase the humidity of the airflow, so that the air mixing channel 203 outputs a high-humidity airflow. The type of humidification component 500 can be selected according to actual conditions.

[0138] Reference Figure 4 In some embodiments, the humidifying assembly 500 is located in the second channel 202 and is used to increase the humidity of the airflow flowing through the second channel 202. That is, the humidifying assembly 500 is directly installed in the second channel 202. When the airflow passes through the second channel 202, the humidifying assembly 500 humidifies the airflow, thereby increasing the humidity of the airflow flowing through the second channel 202.

[0139] Through the above arrangement, the humidification assembly 500 can effectively humidify the airflow, ensuring that the humidity of the airflow reaches the desired level quickly as it passes through the second channel 202. Furthermore, the humidification assembly 500 and the second channel 202 are integrated into a compact structure. Furthermore, the humidification assembly 500 can more accurately control the humidity of the airflow, reducing humidity fluctuations and improving the humidity stability of the storage environment.

[0140] Referring to Figure 4 , in some embodiments, if the second channel 202 may include a plurality of connected parts. Exemplarily, the second channel 202 may include a second channel 202A and a second channel 202B, the second channel 202A and the second channel 202B are connected, and the second channel 202A is located upstream of the second channel 202B.

[0141] It should be noted that the connection between the second channel 202A and the second channel 202B may include various ways. Exemplarily, the second channel 202A and the second channel 202B are directly connected in sequence end to end. Another example is that both the second channel 202A and the second channel 202B are connected to the storage cavity 101, and the air flow in the storage cavity 101 and the air flow in the second channel 202A can enter the second channel 202B. Another example is that the second channel 202A is connected to the second channel 202B through a pipeline, etc.

[0142] It should be noted that the first channel 201 may also include a plurality of parts. The content can refer to the second channel 202 including a plurality of connected parts, which will not be elaborated here.

[0143] In some embodiments, both the second channel 202A and the second channel 202B are connected to the storage cavity 101, and the air flow in the storage cavity 101 and the air flow in the second channel 202A can enter the second channel 202B. The humidifying component 500 is located in the second channel 202A and is used to provide humidified air flow to the second channel 202B. The air flow in the storage cavity 101 and the air flow in the second channel 202 can both flow to the second channel 202A.

[0144] With the above settings, the humidifying component 500 and the second channel 202 are located at different positions. When maintaining or replacing the humidifying component 500, there is no need to disassemble the second channel 202, which can improve the convenience of maintenance.

[0145] Referring to Figure 4 , it can be understood that the number of adjustment components 20 can be multiple.

[0146] In some embodiments, the adjustment component 20 includes a refrigeration component 300, a humidifying component 500, and a heating component 400. The refrigeration component 300 can reduce the temperature of the air flow flowing through the first channel 201, the heating component 400 can increase the temperature of the air flow output from the second channel 202, and the humidifying component 500 can increase the humidity of the air flow output from the second channel 202. In this way, the storage box 10 not only has two temperature adjustment methods with relatively high temperature adjustment accuracy, but also can adjust the humidity. At this time, the storage box 10 can be used for items such as cigars that have relatively high storage requirements for both temperature and humidity.

[0147] Referring to Figure 4In some embodiments, the air circulation assembly 200 further includes a decorative plate 210 , a front cover 220 , and a back plate 240 . The decorative plate 210 , the front cover 220 , the back cover 230 , and the back plate 240 are sequentially arranged along the thickness direction of the box body 100 .

[0148] The front cover 220 is located on the side of the decorative panel 210 facing away from the storage cavity 101. At least a portion of the second passage 202 is formed between the front cover 220 and the decorative panel 210. This means that the second passage 202 can be partially or completely formed between the front cover 220 and the decorative panel 210. The rear cover 230 is located on the side of the front cover 220 facing away from the storage cavity 101. The air mixing passage 203 is formed between the rear cover 230 and the front cover 220. The back panel 240 is located on the side of the rear cover 230 facing away from the storage cavity 101. The first passage 201 is formed between the back panel 240 and the rear cover 230.

[0149] It is understandable that the decorative panel 210 , the front cover 220 , the rear cover 230 and the back panel 240 may be stacked and connected in sequence to form the aforementioned first channel 201 , the second channel 202 and the air mixing channel 203 .

[0150] In some embodiments, a first channel 201 is formed between the back panel 240 and the rear cover 230, and is located in the middle of the rear cover 230. Two second channels 202 are formed between the front cover 220 and the decorative panel 210, and are located on either side of the front cover 220. Furthermore, the first channel 201 and the two second channels 202 are all located in the lower portion of the storage chamber 101. The air mixing channel 203 is located in the upper portion of the storage chamber 101.

[0151] It can be understood that in the above structure, the air flow in the storage chamber 101 enters the first channel 201 and the two second channels 202 respectively, and then the air flow in the first channel 201 and the two second channels 202 enters the mixed air channel 203. Finally, the air flow in the mixed air channel 203 is output into the storage chamber 101, forming an air flow circulation between the storage chamber 101 and the air flow circulation component 200.

[0152] Reference Figure 4 In some embodiments, referring to the above description, if the second channel 202 includes the second channel 202A and the second channel 202B, a first channel 201 is formed between the back plate 240 and the rear cover 230 , and the first channel 201 is located in the middle of the rear cover 230 .

[0153] In some embodiments, the decorative panel 210 and the front cover 220 may jointly form a second channel 202B. The location of the second channel 202A may be selected based on practical needs. In one exemplary embodiment, the second channel 202B is located at the bottom of the storage cavity 101. In another exemplary embodiment, the second channel 202B is located outside the storage cavity 101. In another exemplary embodiment, the second channel 202B is located at the rear of the storage cavity 101.

[0154] In some embodiments, two second channels 202B are formed between the front cover 220 and the decorative panel 210, and are disposed on either side of the front cover 220. Furthermore, the first channel 201 and the two second channels 202B are located at the bottom of the storage chamber 101. The air mixing channel 203 is located at the top of the storage chamber 101.

[0155] It can be understood that in the above structure, the air flow in the storage chamber 101 enters the first channel 201 and the two second channels 202B respectively, and then the air flow in the first channel 201 and the two second channels 202B enters the mixed air channel 203. Finally, the air flow in the mixed air channel 203 is output into the storage chamber 101, forming an air flow circulation between the storage chamber 101 and the air flow circulation component 200.

[0156] Reference Figure 5 In some embodiments, the decorative panel 210 has an air outlet 204 , a first air return outlet 205 , and a second air return outlet 206 .

[0157] Air outlet 204 is located above decorative panel 210 and is connected to air mixing channel outlet 203b and the upper portion of storage chamber 101. Air outlet 204 is used to discharge the mixed airflow, ensuring that it enters storage chamber 101. This upper air outlet helps evenly distribute the airflow within the storage chamber, preventing localized airflow blockages.

[0158] The first air return vent 205 is located below the decorative panel 210 and is connected to the input port of the first duct 201 and to the lower portion of the storage cavity 101. The first air return vent 205 receives air from the storage cavity 101, ensuring that the air within the storage cavity 101 is effectively recycled into the first duct 201.

[0159] The second air return vent 206 is located at the bottom of the decorative panel 210. The second air return vent 206 is connected to the input port of the second channel 202 and to the bottom of the storage cavity 101. The second air return vent 206 is used to receive air from the storage cavity 101, ensuring that the air in the storage cavity 101 can be effectively recycled into the second channel.

[0160] The first return air vent 205 and the second return air vent 206 are connected to different positions of the lower part of the storage chamber 101. By providing multiple return air vents, it is ensured that airflow enters from different positions, thereby ensuring uniform distribution of airflow in the storage chamber 101 to avoid local airflow obstruction.

[0161] In some embodiments, there are multiple first return air vents 205 , the second return air vent 206 is disposed near the center line of the storage cavity 101 , and the multiple first return air vents 205 are disposed outside the second return air vent 206 .

[0162] The multiple first return air vents 205 help ensure that the airflow within the storage chamber 101 can be evenly recovered, avoiding local airflow blockages. The second return air vent 206 is positioned near the centerline of the storage chamber 101 to help concentrate the return air and improve the efficiency of airflow recovery. The first return air vent 205 is positioned outside the second return air vent 206 to facilitate the recovery of peripheral airflow. The design of the return air vents at the outside and centerline positions helps achieve layered recovery of airflow, improves the circulation efficiency of airflow, and ensures the uniformity and stability of airflow circulation within the storage chamber.

[0163] Reference Figure 5 In some embodiments, there are multiple second return air inlets 206 , the first return air inlet 205 is located near the center line of the storage cavity 101 , and the multiple second return air inlets 206 are all located outside the first return air inlet 205 .

[0164] Multiple second return air vents 206 help ensure that the airflow within the storage chamber 101 can be evenly recovered, avoiding local airflow blockages. The placement of the first return air vent 205 near the centerline of the storage chamber 101 helps to concentrate the return air and improve the efficiency of airflow recovery. The second return air vent 206 is located outside the first return air vent 205 to facilitate the recovery of peripheral airflow. The design of the return air vents at the outside and centerline positions helps to achieve stratified airflow recovery, improve the circulation efficiency of the airflow, and ensure the uniformity and stability of the airflow circulation within the storage chamber.

[0165] Reference Figure 6 In some embodiments, the rear cover 230 further includes an auxiliary channel 209. The auxiliary channel 209 is formed at the lower portion of the rear cover 230 and extends through the lower portion of the front cover 220. The input end of the auxiliary channel 209 connects the storage chamber 101 and the first channel 201, namely, a first connection point 231a. The return air chamber 231 connects to the middle of the auxiliary channel 209, namely, a second connection point 231b.

[0166] The airflow process is as follows:

[0167] First, the air flow in the storage cavity 101 enters the auxiliary channel 209 under the action of the blower 250. The air flow enters the return air cavity 231 through the first connection position 231a until the return air cavity 231 is filled with the air flow. Then, the air flow enters the first channel 201 through the second connection position 231b located downstream to perform air flow circulation.

[0168] With the above arrangement, the auxiliary channel 209 can fill the return air cavity 231. The return air cavity 231 filled with gas can serve as an air isolation, effectively isolating the refrigeration component 300 from the storage cavity 101 and preventing the refrigeration component 300 from directly affecting the temperature in the storage cavity 101, which helps to ensure the uniformity of the temperature in the storage cavity 101.

[0169] Referring to Figure 7 , in some embodiments of the present application, the air flow circulation component 200 further includes a first guiding structure 260. The first guiding structure 260 includes a first guiding plate 264, a second guiding plate 265, and a third guiding plate 266. The third guiding plate 266 is located between the first guiding plate 264 and the second guiding plate 265.

[0170] Among them, the second guiding plate 265 and the first guiding plate 264 together form a mixed guiding channel 261, and the mixed guiding channel 261 communicates with the upstream of the air mixing channel 203; a first guiding channel 262 is formed between the third guiding plate 266 and the first guiding plate 264, and the first guiding channel 262 communicates with the downstream of the first channel 201 and the upstream of the mixed guiding channel 261; a second guiding channel 263 is formed between the third guiding plate 266 and the second guiding plate 265, and the second guiding channel 263 communicates with the downstream of the second channel 202 and the upstream of the mixed guiding channel 261.

[0171] In this way, the first guiding structure 260 can form a first guiding channel 262 communicating with the first channel 201, a second guiding channel 263 communicating with the second channel 202, and a mixed guiding channel 261 communicating with the air mixing channel input port 203a, thereby realizing the confluence function and preliminary mixing function of the first guiding structure 260.

[0172] In some embodiments, along the flow direction of the air mixing channel 203, the lengths of both the first guiding plate 264 and the second guiding plate 265 are greater than the length of the third guiding plate 266.

[0173] The longer first guiding plate 264 and second guiding plate 265 have a longer path, enabling the air flow from the first channel 201 to have more time and space for preliminary mixing before entering the mixed guiding channel 261. The shorter length can reduce the resistance of the air flow, ensuring that the air flow can smoothly enter the mixed guiding channel 261 and improving the mixing efficiency.

[0174] It can be understood that, in order to form the above-mentioned first guide channel 262 and second guide channel 263 , the first guide plate 264 , the second guide plate 265 and the third guide plate 266 can all be arc-shaped plates.

[0175] Specifically, the middle portions of the first and second guide plates 264, 265 protrude toward the third guide plate 266. The third guide plate 266 protrudes toward the second guide plate 265, and the protruding portion is located downstream of the first guide channel 262 and at the output of the second guide channel 263, simultaneously serving as the input of the mixing guide channel 261. The protruding portion of the third guide plate 266 is provided with an inlet 267, which serves to establish a three-way connection. A three-way connection refers to interconnection between the mixing guide channel 261, the first guide channel 262, and the second guide channel 263.

[0176] The arc-shaped design and protrusion increase the airflow contact area, reduce resistance and vortex, and improve mixing efficiency. Through the inlet 267, the two airflows can be mixed at the initial stage of converging, thereby improving mixing efficiency.

[0177] It is understood that, in order to ensure connectivity between the multiple guide channels, the angle between the flow direction of the output port of the first guide channel 262 and the flow direction of the output port of the mixing guide channel 261 can be the same as the angle between the flow direction of the output port of the second guide channel 263 and the flow direction of the output port of the mixing guide channel 261.

[0178] The aforementioned first angle refers to the angle between the flow direction of the outlet of the first guide channel 262 and the flow direction of the outlet of the mixing guide channel 261, or the angle between the flow direction of the outlet of the second guide channel 263 and the flow direction of the outlet of the mixing guide channel 261. The first angle has been described above and will not be repeated here.

[0179] Reference Figure 8 In some embodiments, the air circulation assembly 200 further includes a second guide structure 270. The second guide structure 270 includes a first deflection plate 273. The first deflection plate 273 is located at the output port of the first guide structure 260. There are multiple first deflection plates 273, which are arranged at intervals within the air mixing channel 203. A first deflection channel 271 is formed between two adjacent first deflection plates 273. The surface extension direction of the first deflection plates 273 intersects with the flow direction of the air mixing channel 203.

[0180] In this way, the air flow passing through the first diversion channel 271 flows along the first direction A, and the flow direction of the air mixing channel 203 is the second direction B. The first direction A is different from the second direction B, that is, they intersect. Therefore, the air flow flowing along the first direction A and the air flow flowing along the second direction B can be mixed.

[0181] By changing the flow direction, the disturbance and mixing effect of the air flow are increased, ensuring the uniformity and stability of the air flow to improve the uniformity of the storage environment.

[0182] In some embodiments, the angle between the flow direction of the first diversion channel 271 and the flow direction of the air mixing channel 203 is an acute angle, that is, the angle between the first direction A and the second direction B is an acute angle.

[0183] It can be understood that if the angle between the first direction A and the second direction B is an obtuse angle, the first direction A is in the opposite direction of the second direction B, and the resistance between the flow direction of the first diversion channel 271 and the flow direction of the air mixing channel 203 is relatively large, which will affect the flow of the air flow in the air mixing channel 203.

[0184] Refer to Figure 8 , in some embodiments, the flow direction of the first diversion channel 271 is perpendicular to the flow direction of the air mixing channel 203. That is, the angle between the first direction A and the second direction B is a right angle. At this time, the contact area between the air flow passing through the first diversion channel 271 and the air flow not passing through the first diversion channel 271 is relatively large. In this way, the mixing degree between the air flow passing through the first diversion channel 271 and the air flow not passing through the first diversion channel 271 is relatively high, which can improve the mixing effect of the two air flows in the air mixing channel 203.

[0185] Refer to Figure 9 , in some embodiments, the second guiding structure 270 is formed with a plurality of first diversion channels 271, and the flow directions of the plurality of first diversion channels 271 are different from each other. That is, the air flow directions in each of the first diversion channels 271 are different.

[0186] Through the above settings, the mixing of the air flow can also be achieved between adjacent first diversion channels 271, which can improve the disturbance effect and mixing effect of the air flow.

[0187] Refer to Figure 8 , in some embodiments, the second guiding structure 270 is formed with a plurality of first diversion channels 271, and the flow directions of the plurality of first diversion channels 271 are the same. That is, the air flow directions in each of the first diversion channels 271 are the same, which can ensure that the second guiding structure 270 can output an air flow with a consistent flow path, improving the uniformity and stability of the air flow.

[0188] In some embodiments, the first flow deflector 273 is configured to cause the air flow to flow in the first flow deflection channel 271 and change the Reynolds number of the air flow until the flow state of the air flow changes to turbulence.

[0189] It can be understood that if the flow state of the air flow is turbulent, it means that the air flow output from the first channel 201 and the air flow output from the second channel 202 flow in an irregular and chaotic manner, and the two air flows are strongly mixed, so that the second guiding structure 270 can enhance the mixing degree of the air flow, ensure the uniformity and stability of the air flow, and improve the uniformity of the storage environment.

[0190] In some embodiments, according to Re = ρvL0 / μ, where Re is the Reynolds number required for the flow state of the air flow to be turbulent, ρ is the density of the air flow, v is the flow velocity of the air flow, L0 is the characteristic length required for the flow state of the air flow to change to turbulence, and μ is the dynamic viscosity of the air flow. According to the above content, when the conditions such as density, flow velocity, and dynamic viscosity remain unchanged, the Reynolds number is proportional to the characteristic length. Therefore, by adjusting the characteristic length, the Reynolds number of the air flow can be changed.

[0191] It can be understood that when the Reynolds number of the air flow is low (for example, less than 2000), the flow state of the air flow is usually laminar. Therefore, in order to make the air flow change to a turbulent state in the first flow deflection channel 271, it is necessary to increase the Reynolds number of the air flow.

[0192] Exemplarily, if the Reynolds number of the air flow reaches 2300, that is, Re = 2300 can effectively trigger the turbulence of the air flow. In this example, assuming v = 6m / s, μ = 0.0000179Pa.s, ρ = 1.29, at this time, L0 = 5.3mm is obtained. That is, if the extension length of the first flow deflector 273 is 5.3mm, the turbulence of the air flow can be triggered, thereby enhancing the mixing degree of the air flow.

[0193] It should be noted that the above data are only examples and can be adjusted according to the actual situation.

[0194] In some embodiments, the actual extension length of the first flow deflector 273 is L, and the relationship between L and L0 is: L0*0.4 < L < L0*1.6.

[0195] It can be understood that a reasonable ratio helps the air flow to complete the change of the air flow state in the first flow deflection channel 271.

[0196] When the first deflector 273 is at the above ratio, the first deflector 273 can effectively change the flow state of the air flow, so that the flow state of the air flow is turbulent, thereby improving the mixing degree of the air flow. If L is less than the above ratio, the first deflector 273 is short and cannot increase the Reynolds number of the air flow, so turbulence cannot be induced; if L is greater than the above ratio, the first deflector 273 is long, and the flow resistance of the air flow increases, thereby affecting the flow of the air flow in the first diversion channel 271.

[0197] In some embodiments, the relationship between L and L0 is: L0*0.5≤L≤L0*1.5. At this time, L0 can be an integer. On this basis, L can take half of L0. At this time, while achieving turbulence, it is convenient to process the first deflector 273 with an integer length, reducing the production accuracy and assembly accuracy of the first deflector 273.

[0198] In some embodiments, the shape of the first deflector 273 can be arbitrary. Exemplarily, the first deflector 273 can be a plate body or a column body. Another example is that the end face of the first deflector 273 can be circular, rectangular, or rounded rectangular, etc.

[0199] It can be understood that the aforementioned second angle refers to the angle between the flow direction of the first diversion channel 273 (i.e., the first direction A) and the flow direction of the air mixing channel 203 (i.e., the second direction B). The content of the second angle has been described in the foregoing text and will not be elaborated here.

[0200] Refer to Figure 8 , in some embodiments, when the surface extension directions of multiple first deflectors 273 are the same, the flow directions of multiple first diversion channels 271 are the same. That is, the air flow directions in each first diversion channel 271 are the same, which can ensure that the second guiding structure 270 can output air flow with a consistent flow path, improving the uniformity and stability of the air flow.

[0201] Refer to Figure 10 , in some embodiments, along the surface extension direction of the first deflector 273, the length of the first deflector 273 is L, and the distance between two adjacent first deflectors 273 is S1. The relationship between L and S1 is: L < S1 < L*5.

[0202] It should be noted that the distance S1 can affect the size of the flow space of the air flow between two adjacent first deflectors 273.

[0203] It can be understood that a reasonable distance S1 helps the air flow to be fully mixed between adjacent first deflection plates 273, improving the mixing efficiency. If S1 is less than the above ratio, the distance between adjacent first deflection plates 273 is too small, which may cause the air flow to not smoothly enter the first deflection channel 271, thereby affecting the air flow; if S1 is greater than the above ratio, the distance between adjacent first deflection plates 273 is too large, and the flow rate of the air flow introduced into the first deflection channel 271 is low, thereby affecting the Reynolds number of the air flow, and thus the change in the air flow state cannot be achieved.

[0204] Referring to Figure 10 , in some embodiments, along the surface extension direction of the first deflection plate 273, the length of the first deflection plate 273 is L, and the distance between adjacent first deflection plates 273 is S1. The relationship between L and S1 is: L * 2 ≤ S1 ≤ L * 4.

[0205] If S1 is between one times L and two times L, although the air flow state can be changed, the air flow path is short, and there may be a situation where only the air flow state of part of the air flow changes; if S1 is between four times L and five times L, although the air flow path is sufficient to ensure that the air flow state of all the air flow changes, there is also a possibility that the air flow cannot smoothly enter the second deflection channel 272.

[0206] In some embodiments, the second guiding structure 270 forms a second deflection channel 272. The second deflection channel 272 is located downstream of the first deflection channel 271, and the flow direction of the second deflection channel 272 is the same as the flow direction of the air mixing channel 203, that is, the air flow passing through the second deflection channel 272 also flows along the second direction B. In this way, when the first deflection channel 271 outputs the air flow, the second deflection channel 272 can change the air flow output by the first deflection channel 271 and mix it again; at the same time, the second deflection channel 272 can provide a guiding function to improve the uniformity of the air flow, ensuring that the air mixing channel 203 can output an air flow with a higher mixing degree and higher uniformity.

[0207] Referring to Figure 10 , in some embodiments, the second guiding structure 270 further includes second deflection plates 274. The second deflection plates 274 are located at the output ports of the first deflection plates 273. The number of the second deflection plates 274 is multiple, and the multiple second deflection plates 274 are arranged at intervals in the air mixing channel 203. A second deflection channel 272 is formed between adjacent second deflection plates 274; the surface extension direction of the second deflection plates 274 is the same as the flow direction of the air mixing channel 203.

[0208] In some embodiments, the second flow deflector 274 is configured to enable the air flow to flow within the second flow deflection channel 272 and change the Reynolds number of the air flow until the flow state of the air flow changes from turbulent flow to laminar flow.

[0209] It can be understood that, according to the above content, when the Reynolds number of the air flow is low (for example, less than 2000), the flow state of the air flow is usually laminar flow. Therefore, in order to enable the air flow to transform into a laminar flow state within the second flow deflection channel 272, it is necessary to reduce the Reynolds number of the air flow.

[0210] It can be understood that if the flow state of the air flow is laminar flow, it means that the second flow deflector 274 can receive the air flow output from the first flow deflection channel 273 and flow in a parallel path to enhance the flow consistency of the air flow within the air mixing channel 203, thereby ensuring the uniformity and stability of the air flow output and improving the uniformity of the storage environment.

[0211] Exemplarily, the extension length of the second flow deflector 274 is less than the extension direction of the first flow deflector 273, which can effectively reduce the Reynolds number of the air flow.

[0212] Another exemplarily, no structure is provided between the second flow deflector 274 and the first flow deflector 273, that is, the air flow enters the mixing channel 203 after passing through the first flow deflection channel 271. Since the maximum aperture that the mixing channel 203 can pass the air flow through is much larger than the maximum aperture of the first flow deflection channel 271, the density of the air flow rapidly decreases, and the Reynolds number of the air flow can also be reduced.

[0213] Referring to Figure 10 , in some embodiments, when the surface extension direction of the first flow deflector 273 is perpendicular to the flow direction of the air mixing channel 203, the minimum distance between the adjacent first flow deflector 273 and the second flow deflector 274 is S2, and the relationship between L and S2 is: L < S2 < L * 6.

[0214] It should be noted that the distance S2 can affect the flow space between the first flow deflector 273 and the second flow deflector 274.

[0215] It can be understood that a reasonable distance S2 helps the air flow to change its flow state between the first flow deflector 273 and the second flow deflector 274. If S2 is less than the above ratio, the distance between the first flow deflector 273 and the second flow deflector 274 is too small to effectively change the flow state of the air flow, and thus the output of laminar air flow cannot be achieved; if S2 is greater than the above ratio, the distance between the first flow deflector 273 and the second flow deflector 274 is too large, which may cause the air flow to not smoothly enter the second flow deflection channel 272, thereby affecting the flow of the air flow.

[0216] In some embodiments, along the flow direction of the air mixing channel 203, the distance between the adjacent first flow direction changing plate 273 and the second flow direction changing plate 274 is S2, and the relationship between L and S2 is: L*2 ≤ S2 ≤ L*5.

[0217] If S2 is between one times L and two times L, although the flow state of the air flow can be changed, the flow path of the air flow is short, and there may be a situation where only the flow state of part of the air flow is changed; if S1 is between five times L and six times L, although the flow path of the air flow is sufficient to ensure that the flow state of all the air flow is changed, there is also a possibility that the air flow cannot smoothly enter the second flow direction changing channel 272.

[0218] It can be understood that when the air flow circulation assembly 200 includes the first guiding structure 260 and the second guiding structure 270, the air flow process is as follows:

[0219] First, the air flow in the storage cavity 101 enters the first channel 201 and the second channel 202 respectively through the input ports of the first channel 201 and the second channel 202 under the influence of the fan 250. Then, the air flow in the first channel 201 enters the mixed guiding channel 261 through the first guiding channel 262. At the same time, the air flow in the second channel 202 enters the mixed guiding channel 261 through the second guiding channel 263. Then, the first guiding structure 260 changes the air flow direction for preliminary mixing and outputs it to the air mixing channel input port 203a. Then, the air flow passes through the first flow direction changing channel 271, the air flow direction changes, and the air flow is mixed again. Then, the air flow passes through the second flow direction changing channel 272 or passes through the short air mixing channel and then passes through the second flow direction changing channel 272. The second flow direction changing channel 272 is used to guide the air flow to the air mixing channel output port 203b. Finally, the air flow passes through the air mixing channel output port 203b and enters the storage cavity 101 to form an air flow cycle.

[0220] Refer to Figure 8 , in some embodiments, the air flow circulation assembly 200 further includes a third guiding structure 280. The third guiding structure 280 is communicated with the air mixing channel output port 203b, and the aperture of the output port of the third guiding structure 280 is larger than the aperture of the air mixing channel output port 203b.

[0221] By increasing the aperture of the output port, the flow rate of the air flow can be reduced, gentle air output can be achieved, and it is ensured that the air flow circulation in the storage cavity 101 is relatively stable and uniform.

[0222] Refer to Figure 8In some embodiments, the third guide structure 280 forms a first outlet channel 281, which communicates with the air mixing channel outlet 203b. The outlet aperture of the first outlet channel 281 is larger than the outlet aperture of the air mixing channel 203b. Increasing the outlet aperture reduces the airflow velocity, achieving a smoother airflow and ensuring a more stable and uniform airflow circulation within the storage chamber 101.

[0223] In some embodiments, the third guide structure 280 forms a second outlet channel 282, which communicates with the air mixing channel outlet 203b. The outlet aperture of the second outlet channel 282 is larger than the outlet aperture of the air mixing channel 203b. By increasing the outlet aperture, the airflow velocity can be reduced, achieving a smoother air flow and ensuring a more stable and uniform airflow circulation within the storage chamber 101.

[0224] In some embodiments, the aperture of the outlet of the first outlet channel 281 is different from the aperture of the outlet of the second outlet channel 282. By designing the outlet apertures of different sizes, the airflow can be distributed as needed when leaving the air mixing channel 203, the flow rate of the airflow can be reduced, and different degrees of soft airflow can be achieved.

[0225] In some embodiments, the aperture of the output port of the first outlet channel 281 may be larger than the aperture of the output port of the second outlet channel 282 , or may be smaller than the aperture of the output port of the second outlet channel 282 .

[0226] It is understood that a larger outlet aperture can achieve a greater degree of soft air discharge, while a smaller outlet aperture can achieve a lesser degree of soft air discharge. Through the above arrangement, the storage box 10 can adjust the positions of the first outlet channel 281 and the second outlet channel 282 according to the stored items to match the items with different needs, thereby achieving adaptive soft air discharge.

[0227] In some embodiments, the ratio of the aperture of the output port of the first outlet channel 281 to the aperture of the output port of the air mixing channel 203 is greater than or equal to 3.

[0228] When the aperture of the output port of the first outlet channel 281 is 3 times or more than the aperture of the mixed air channel output port 203b, the airflow will significantly reduce its flow rate during output to achieve soft air outlet, ensuring that the airflow circulation in the storage cavity 101 is relatively stable and uniform.

[0229] Soft air flow can reduce direct impact on stored items and protect the integrity of stored items.

[0230] In some embodiments, the ratio of the aperture of the output port of the second outlet channel 282 to the aperture of the air mixing channel output port 203 b is greater than or equal to 3.

[0231] When the aperture of the outlet of the second air guiding channel 282 is 3 times or more of the aperture of the outlet of the air mixing channel 203b, the air flow rate will be significantly reduced when the air flows out, so as to achieve gentle air outlet and ensure relatively stable and uniform air flow circulation in the storage cavity 101.

[0232] Gentle air outlet can reduce the direct impact on the stored items and protect the integrity of the stored items.

[0233] It can be understood that if the aforementioned ratio is too small, the aperture of the outlet of the air mixing channel 203b cannot be effectively increased, and the air outlet volume cannot reach the standard of gentle air outlet, and thus gentle air outlet cannot be effectively achieved.

[0234] Refer to Figure 4 , in some embodiments, the first air guiding channel 281 and the second air guiding channel 282 may be located at different positions in the storage cavity 101. For example, the first air guiding channel 281 may be located above the second air guiding channel 282; for example, the first air guiding channel 281 may be located below the second air guiding channel 282. The lower channel is closer to the items in the storage cavity 101 than the upper channel.

[0235] In some embodiments, the aperture of the outlet of the first air guiding channel 281 is larger than the aperture of the outlet of the second air guiding channel 282, and the first air guiding channel 281 is located below the second air guiding channel 282.

[0236] Through the above settings, the first air guiding channel 281 is close to the items in the storage cavity 101 and has a larger outlet aperture, which can ensure that the air flow rate will be significantly reduced when the air flows out, so as to achieve gentle air outlet and ensure relatively stable and uniform air flow circulation in the storage cavity 101.

[0237] Refer to Figure 4 , in some embodiments, when the aforementioned third guiding structure 280 is arranged in the air mixing channel 203, the air outlet 204 includes a first air outlet 207 and a second air outlet 208, the first air outlet 207 communicates with the first air guiding channel 281, and the second air outlet 208 communicates with the second air guiding channel 282.

[0238] Refer to Figure 11, in some embodiments, the air flow circulation component 200 includes the aforementioned decorative plate 210, front cover 220, rear cover 230 and rear plate 240. Two second channels 202B are formed between the decorative plate 210 and the front cover 220. The second channel 202A is located at the bottom of the storage cavity 101. The second channel 202A is located upstream of the second channel 202B. The outlets of the two second channels 202B are communicated. A first channel 201 is formed between the front cover 220 and the rear cover 210. The decorative plate 210 has a first air return opening 205 corresponding to the first channel 201 and two parts of second air return openings 206 corresponding to the two second channels 202B.

[0239] The first air return opening 205 communicates with the middle position of the lower part of the storage cavity 101. The first air return opening 205 can communicate with the auxiliary channel 209.

[0240] First, a part of the air flow a1 in the storage cavity 101 enters the auxiliary channel 209 through the first air return opening 205. After filling the air return cavity 231 between the front cover 220 and the rear cover 230, the air flow a1 enters the first channel 201.

[0241] Referring to Figure 12 , the refrigeration component 270 includes an evaporator 310. The evaporator 310 is close to the input port of the first channel 201. The evaporator 310 cools the air flow and reduces the humidity. A second fan 252 is provided on the output side of the evaporator 310. The second fan 252 is a centrifugal fan, which can suck the air flow output by the evaporator 271 and direct the air flow to the air mixing channel 203.

[0242] The second air return opening 206 communicates with both sides of the lower part of the storage cavity 101 and is communicated with the output side of the humidification component 500. The humidification component 500 can output a humidified air flow a3, which enters the second channel 202B through the second air return opening 206.

[0243] At the same time, another part of the air flow a2 in the storage cavity 101 and the humidified air flow a3 output by the humidification component 500 pass through the second air return opening 206 and enter the two first channels 201 respectively. Each of the two first channels 201 is provided with a first fan 251. The first fan 251 is an axial fan, which can direct the air flow to the air mixing channel 203.

[0244] Among them, two heating components 400 are close to the output port positions of the two second channels 202B to increase the temperature of the air flow flowing through the two second channels 202B. In this way, the first channel 201 outputs a cooled and dehumidified air flow a4, and the second channel 202B outputs a heated and humidified air flow a5.

[0245] Then, the two airflows respectively enter the first guiding channel 262 and the second guiding channel 263 formed by the first guiding structure 260. The velocities of the two airflows change, and preliminary mixing is completed in the mixed guiding channel 261.

[0246] Then, the second guiding structure 270 receives the airflow output by the first guiding structure 270 and passes through the first diversion channel 271. The adjacent first diversion plates 273 form the first diversion channel 271. The first diversion plates 273 can change the Reynolds number of the airflow to change the airflow from the laminar state to the turbulent state, enhancing the mixing degree of the two airflows. The airflow output from the first diversion channel 271 briefly enters the air mixing channel 203 and then enters the second diversion channel 272 of the second guiding structure 270. The adjacent second diversion plates 274 form the second diversion channel 272. The second diversion plates 274 can change the airflow from the turbulent state to the laminar state.

[0247] Then, the third guiding structure 280 receives the airflow a6 output from the second diversion channel 272. The third guiding structure 280 forms a first outlet channel 281 and a second outlet channel 282. The calibers of the outlets of the first outlet channel 281 and the second outlet channel 282 both increase, enabling gentle air outlet of the airflow. The outlet of the first outlet channel 281 is located above the outlet of the second outlet channel 282. The outlet of the first outlet channel 281 is communicated with the first air outlet 207, and the airflow a7 enters the storage cavity 101 through the first air outlet 207. The outlet of the second outlet channel 282 is communicated with the second air outlet 208, and the airflow a8 enters the storage cavity 101 through the first air outlet 207.

[0248] Then, within the air mixing channel 203 of the air circulation assembly 200, the physical parameters of the airflow output from the air mixing channel 203 are between the physical parameters of the airflow in the storage cavity 101 and the physical parameters of the airflow received by the air mixing channel 203.

[0249] Between the airflow a7, airflow a8 received by the storage cavity 101 and the released airflow a1, airflow a2, the fluctuations of the physical parameter changes are relatively small. In this way, with the same airflow flowing time, the physical parameters of the airflow change multiple times. Compared with single - time changes, the adjustment accuracy of the physical parameters increases, which can reduce the deviation between the actual airflow and the target airflow, facilitating the formation of storage conditions with constant physical parameters. Furthermore, the airflow in the storage cavity 101 can be within the preset range, which is beneficial to item storage.
