Description

Technical Field

[0001] The embodiments of the present application relate to storage equipment technology, and more particularly to a storage box. Background Art

[0002] With the development of science and technology and the improvement of living standards, people have higher requirements for the storage period of items. For most items, low temperature and constant humidity are the preferred storage conditions.

[0003] In the related art, a refrigerator is installed inside a storage cabinet to maintain a low temperature. The refrigerator absorbs heat from the space to maintain the low temperature inside the cabinet. The humidity of the environment tends to decrease with storage time, so a humidifier is usually installed inside the cabinet to increase the humidity. An evaporator is generally used as the refrigerator.

[0004] However, the working principle of the evaporator is to evaporate the moisture in the air to absorb heat. The evaporator and the refrigerator are both located inside the storage cabinet. The evaporator will affect the humidity control accuracy of the storage cabinet, which in turn affects the storage of items. Utility Model Content

[0005] Some embodiments of the present application provide a storage box, which is provided with two independent channels, and a refrigeration component and a humidification component are respectively arranged in the two channels. The two channels are isolated by a front cover, and then the refrigeration component and the humidification component are isolated, so that the humidification component and the refrigeration component cannot contact each other, thereby preventing the refrigeration component from affecting the humidity in the storage cavity, and ensuring precise adjustment of the humidity.

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

[0007] The box body defines a storage cavity therein;

[0008] Air circulation assembly having:

[0009] a first channel, wherein an input port of the first channel is connected to the storage cavity;

[0010] a second channel, wherein an input port of the second channel is connected to the storage cavity;

[0011] Mixed air channel, with:

[0012] An air mixing channel input port is connected to an output port of the first channel and an output port of the second channel;

[0013] An air mixing channel output port is connected to the storage cavity;

[0014] The airflow circulation component includes:

[0015] a front cover, wherein a side of the front cover away from the storage cavity forms the first channel, and a side of the front cover close to the storage cavity forms the second 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, located in the first channel, and configured to reduce the temperature of the airflow flowing through the first channel;

[0018] The humidifying component is connected to the second channel and is used to increase the humidity of the airflow flowing through the second channel.

[0019] Some embodiments of the present application provide storage boxes comprising a storage cavity and an air circulation assembly connected to the storage cavity. The air circulation assembly receives air from the storage cavity through a first channel and a second channel, respectively. The first channel and the second channel are formed on the front and rear sides of a front cover, respectively, and a cooling assembly and a humidifying assembly are disposed within the first channel and the second channel, respectively. This prevents the air humidified by the humidifying assembly from flowing through the cooling assembly, preventing the cooling assembly from absorbing moisture from the humidified air. This ensures that the humidifying assembly can accurately regulate the humidity of the air, thereby improving the humidity control accuracy of the storage box and facilitating storage of items.

[0020] In some embodiments of the present application, along the extension direction of the surface of the front cover, the input port of the first channel and the input port of the second channel are arranged at intervals.

[0021] This spacing design helps prevent the airflow from the two channels from mixing directly, ensuring that the cooling and humidification processes are carried out independently. This prevents the humidified airflow from being re-cooled and dehumidified by the refrigeration component before entering the storage chamber, thereby improving the accuracy of humidity control.

[0022] In some embodiments of the present application, the number of the second channels is two;

[0023] Along the extension direction of the surface of the front cover, the two input ports of the second channels are respectively located on opposite sides of the lower portion of the front cover;

[0024] The input port of the first channel is located in the middle of the lower part of the front cover.

[0025] This arrangement allows the airflow to enter the first channel from the middle position of the storage cavity to separate it from the two second channels distributed on both sides of the storage cavity, which can prevent the humidified airflow from flowing back into the second channel and further prevent the refrigeration component from receiving the humidified airflow.

[0026] In some embodiments of the present application, the fan includes:

[0027] The second fan is two in number, and the two second fans are respectively located in the two first channels, and are used to drive the airflow in the first channels to flow toward the air mixing channel.

[0028] With such an arrangement, a plurality of second fans can work simultaneously, thereby increasing the speed of the airflow through the second channel, and further increasing the airflow circulation speed between the storage cavity and the airflow circulation component.

[0029] In some embodiments of the present application, the second fan is an axial fan, the axis of the axial fan is perpendicular to the extension direction of the surface of the front cover, and the input port of the axial fan faces the storage cavity.

[0030] With this arrangement, the axial fan can direct the airflow to the air mixing channel.

[0031] In some embodiments of the present application, the airflow circulation component further includes:

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

[0034] 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.

[0035] 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.

[0036] In some embodiments of the present application, the airflow circulation assembly includes a first guide structure, and the first guide structure includes:

[0037] a first guide plate;

[0038] 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;

[0039] 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;

[0040] 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;

[0041] 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.

[0042] 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.

[0043] In some embodiments of the present application, the airflow circulation assembly includes a second guide structure, and the second guide structure includes:

[0044] 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;

[0045] There are multiple first deflection plates, and the multiple first deflection plates are arranged at intervals in the air mixing channel;

[0046] 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;

[0047] 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.

[0048] 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.

[0049] In some embodiments of the present application, the second guide structure further includes:

[0050] 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.

[0051] 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;

[0052] 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.

[0053] 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.

[0054] In some embodiments of the present application, the airflow circulation assembly includes a third guide structure, and the third guide structure includes:

[0055] 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;

[0056] 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,

[0057] 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.

[0058] 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

[0085] 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.

[0086] 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.

[0087] In addition, the terms "comprises" and "comprising" and any variations thereof are intended to cover but not exclude inclusion, for example, a product or device comprising a list of components is not necessarily limited to those components expressly listed but may include other components not expressly listed or inherent to such product or device.

[0088] In the description of this application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and 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, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0089] 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 the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. Throughout this application, unless otherwise specified, "plurality" means two or more.

[0090] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0091] The following will be combined with the accompanying drawings of some embodiments of the present application to clearly and completely describe the technical solutions of some embodiments of the present application. Obviously, the embodiments described are only some embodiments of the present application, not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of this application.

[0092] In related technologies, such as the constant temperature and humidity chamber with variable frequency refrigeration function disclosed in Chinese patent CN218742040U, the refrigeration component works to allow cold air to enter the processing chamber through the delivery hole, the heating component can heat the air, and the hot air flow can move upward and flow through the humidifying electric heating tube, evaporator, and heating electric heating tube in sequence. The fan mixes the cold and hot wet air and then sends it into the mixing chamber. However, in the above solution, the humidity of the air flow passing through the humidifying electric heating tube increases, and the evaporator easily evaporates the moisture in the air flow. That is, the moisture added by the humidifying electric heating tube is consumed by the evaporator. The humidity of the air flow adjusted by the humidifying electric heating tube is different from the humidity of the storage environment. The humidity accuracy in the storage environment is low, which can easily affect the storage of items.

[0093] 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 connected to the storage cavity. The air flow circulation component receives the airflow from the storage cavity through a first channel and a second channel respectively, and forms the first channel and the second channel on the front and rear sides of the front cover respectively, and a refrigeration component and a humidification component are respectively arranged in the first channel and the second channel.

[0094] In this way, the airflow humidified by the humidifying component does not flow through the refrigeration component, and the refrigeration component cannot absorb the moisture of the humidified airflow, thereby ensuring the precise adjustment of the airflow humidity by the humidifying component, improving the humidity adjustment accuracy of the storage box, and facilitating the storage of items.

[0095] In this application, it should be understood that the terms involved have the following meanings:

[0096] Ventilation volume: the volume of air passing through a certain section per unit time.

[0097] Venturi Effect: According to the fluid continuity equation and Bernoulli's equation, when a fluid flows through a constricted pipe, its kinetic energy increases due to the increase in the fluid's velocity, while its pressure energy decreases accordingly. This means that the fluid's velocity is highest and its pressure is lowest in the narrow part of the constricted pipe.

[0098] Preset range: Adapt to the storage conditions of the stored items.

[0099] Laminar flow: refers to the flow of fluid particles in parallel paths or layers without mixing with each other.

[0100] Turbulence: refers to the flow of fluid particles in an irregular and chaotic manner, with strong mixing and vortexes occurring within the fluid.

[0101] Reference 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 is formed inside, namely a storage cavity 101. In this way, the box body 100 can provide a closed storage space, which is convenient for controlling the internal environmental conditions.

[0102] Reference Figure 2 In some embodiments, the storage box 10 includes an airflow circulation component 200, which is used to regulate the airflow in the storage cavity 101, including but not limited to regulating the flow rate, ventilation volume, temperature, humidity, oxygen content, etc.

[0103] In some embodiments, the air circulation assembly 200 is located outside the storage box 10 , that is, the air circulation assembly 200 does not occupy the storage cavity 101 , so as to facilitate storage of more items.

[0104] Reference Figure 1 In some embodiments, the airflow circulation component 200 is located inside the storage box 10, that is, the airflow circulation component 200 is located inside the storage box 10, which facilitates the airflow circulation component 200 to receive the airflow output from the storage cavity 101, and at the same time facilitates the airflow circulation component 200 to output the airflow from the storage cavity 101.

[0105] In some embodiments, the airflow circulation assembly 200 has a first channel 201 for conveying airflow. The first channel 201 has an input port and an output port. The side where airflow enters the first channel 201 is the input port, and the side where airflow exits the first channel 201 is the output port. The input port of the first channel 201 is connected to the storage chamber 101, that is, the first channel 201 is connected to the storage chamber 101, and the first channel 201 can receive airflow within the storage chamber 101.

[0106] In some embodiments, the air circulation assembly 200 includes a second channel 202 for conveying airflow. The second channel 202 also has an input port and an output port, which are not described in detail here. The input port of the second channel 202 communicates with the storage chamber 101, that is, the second channel 202 is connected to the storage chamber 101, and the second channel 202 can receive airflow within the storage chamber 101.

[0107] In some embodiments, the air flow circulation component 200 has an air mixing channel 203, the air mixing channel 203 has an air mixing channel input port 203a and an air mixing channel output port 203b, the air mixing channel input port 203a is connected to the output port of the first channel 201 and the output port of the second channel 202 at the same time, the air mixing channel output port 203b is connected to the storage cavity 101, and the air mixing channel 203 is used to receive the airflow input from the first channel 201 and the second channel 202, and output it to the storage cavity 101 after mixing.

[0108] It is understood that the first channel 201 and the second channel 202 each form an airflow, and thus the two airflows enter the air mixing channel 203 and are mixed within the air mixing channel 203. Therefore, the physical parameters of the airflow output from the air mixing channel 203 are between the physical parameters of the airflow in the first channel 201 and the physical parameters of the airflow in the second channel 202.

[0109] That is, the physical parameters of the airflow output by the airflow circulation component 200 are between the physical parameters of the airflow received by the airflow circulation component 200 and the physical parameters of the airflow inside the airflow circulation component 200 .

[0110] In some embodiments, the airflow circulation assembly 200 includes a fan 250 , which is used to drive the airflow.

[0111] It is understood that fan 250 can be an axial fan, where the airflow is caused to flow axially along the fan blades. Fan 250 can also be a centrifugal fan, where the airflow is caused to flow radially along the fan blades. Fan 250 can also be a mixed flow fan, where the airflow is caused to flow partially axially and partially radially along the fan blades.

[0112] In some embodiments, the fan 250 is located in at least one of the first channel 201, the second channel 202 and the mixed air channel 203, so that the airflow output from the storage chamber 101 can enter the airflow circulation component 200, and the airflow output from the airflow circulation component 200 can flow back to the storage chamber 101, forming an airflow circulation of the storage chamber 101-airflow circulation component 200-storage chamber 101.

[0113] Reference Figure 1 In some embodiments, the airflow circulation component 200 includes an adjustment component 20 for changing the physical parameters of the airflow. The physical parameters include but are not limited to the aforementioned temperature, humidity, oxygen content, etc.

[0114] In some embodiments, the adjustment component 20 is located in at least one of the first channel 201 and the second channel 202, that is, the adjustment component 20 can adjust the airflow that has not entered the mixed air channel 203, such as increasing the airflow temperature, decreasing the airflow temperature, increasing the airflow humidity, decreasing the airflow humidity, increasing the airflow oxygen content, decreasing the airflow oxygen content, etc.

[0115] It should be noted that the shape, position, and composition of the first channel 201 and the second channel 202 referred to in some embodiments of the present application can be selected according to actual conditions. For example, the second channel 202 can include multiple connected parts, and two parts are not adjacent in position but have air flow.

[0116] Reference Figure 1 In some embodiments, when the physical parameter includes temperature, the adjustment assembly 20 includes a cooling assembly 300. The cooling assembly 300 is located within the first channel 201 and is configured to reduce the temperature of the airflow flowing through the first channel 201, thereby causing the air mixing channel 203 to output a lower temperature airflow. The type of cooling assembly 300 can be selected based on actual conditions.

[0117] In some embodiments, the refrigeration component 300 can be a vapor compression refrigeration system. When the refrigeration component 300 is a vapor compression refrigeration system, the vapor compression refrigeration system includes an evaporator 310. The evaporator 310 can vaporize the moisture in the air flow passing through, thereby absorbing heat to complete refrigeration while reducing the humidity of the air flow.

[0118] Reference Figure 1 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.

[0119] Reference Figure 1In some embodiments, a first channel 201 is formed on a side of the front cover 220 away from the storage cavity 101, that is, the first channel 201 to 201 is formed between the front cover 220 and the rear cover 230. Figure 5 A second channel 202 is formed on a side of the front cover 220 close to the storage cavity 101 , that is, the second channel 202 is formed between the front cover 220 and the decorative panel 210 .

[0120] The specific airflow process is as follows:

[0121] First, the airflow in the storage chamber 101 is divided into two streams under the influence of the fan 250. One stream enters the first channel 201, and the refrigeration component 300 can cool the airflow flowing through the first channel 201; the other stream enters the second channel 202 to humidify the air. 500 can humidify the airflow flowing through the second channel 202. Then, the cooled airflow and the humidified airflow enter the air mixing channel 203 through the air mixing channel input port 203a. Then, the cooled airflow and the humidified airflow are mixed in the air mixing channel 203 and enter the storage chamber 101 through the air mixing channel output port 203b, forming an airflow cycle.

[0122] From the above content, it can be seen that the air flow is divided into two streams in the storage cavity 101. The two air flows pass through the refrigeration component 300 and the humidification component 500 respectively, and are output after being mixed in the air mixing channel 203. The humidification component 500 cannot receive the cooled air flow, and thus cannot affect the humidity of the air flow entering the storage cavity 101. The humidity adjustment accuracy of the storage box 10 can be improved, which is beneficial to the storage of items.

[0123] Reference Figure 3 In some embodiments, along the extension direction of the surface of the front cover 220 , the input port of the first channel 201 and the input port of the second channel 202 are arranged at intervals.

[0124] The spacing design helps prevent the airflows from the two channels from directly mixing, ensuring that the cooling and humidification processes are carried out independently. This prevents the humidified airflow from being re-cooled and dehumidified by the refrigeration component before entering the storage chamber 101, thereby improving the accuracy of humidity regulation.

[0125] Reference Figure 3 In some embodiments, there are two second channels 202, i.e., two second channels 202 are formed between the decorative plate 210 and the front cover 220. By increasing the number of second channels 202, the humidification capacity of the humidification assembly 500 can be improved, thereby adjusting the humidity in the storage chamber 101 more quickly.

[0126] Along the surface extension direction of the front cover 220 , the input ports of the two second channels 202 are respectively located on opposite sides of the lower portion of the front cover 220 . The input port of the first channel 201 is located in the middle of the lower portion of the front cover 220 .

[0127] In this way, the airflow can enter the first channel 201 from the middle position of the storage chamber 101 to be separated from the two second channels 202 distributed on both sides of the storage chamber 101, which can prevent the humidified airflow from flowing back into the second channel 202 and further prevent the refrigeration component 300 from receiving the humidified airflow.

[0128] Reference Figure 4 In some embodiments, the fan 250 includes two second fans 252, each located in one of the two first channels 201, for driving the airflow in the first channels 201 toward the air mixing channel 203. In this way, multiple second fans 252 can operate simultaneously, increasing the speed of airflow through the second channels 202 and, in turn, the speed of airflow circulation between the storage chamber 101 and the air circulation assembly 200.

[0129] In some embodiments, the second fan 252 is an axial fan, the axis of which is perpendicular to the surface extension direction of the front cover 220 , and the input port of the axial fan faces the storage cavity 101 . The axial fan can direct the airflow to the air mixing channel 203 .

[0130] Reference Figure 5 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.

[0131] Reference Figure 5 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.

[0132] 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.

[0133] Reference Figure 5 In some embodiments, if the second channel 202 includes multiple connected parts, for example, 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.

[0134] It should be noted that the second channel 202A and the second channel 202B can be connected in various ways. For example, the second channel 202A and the second channel 202B are directly connected end to end. In another example, the second channel 202A and the second channel 202B are both connected to the storage chamber 101, so that the airflow within the storage chamber 101 and the airflow within the second channel 202A can enter the second channel 202B. In another example, the second channel 202A is connected to the second channel 202B via a pipe.

[0135] It should be noted that the first channel 201 may also include multiple parts, the contents of which can be referred to as the multiple connected parts of the second channel 202, which will not be described in detail here.

[0136] In some embodiments, both second channel 202A and second channel 202B are connected to storage chamber 101, allowing airflow within storage chamber 101 and airflow within second channel 202A to flow into second channel 202B. Humidifier assembly 500 is located in second channel 202A and is configured to provide humidified airflow to second channel 202B. Airflow within storage chamber 101 and airflow within second channel 202 can both flow into second channel 202A.

[0137] Through the above arrangement, the humidifying component 500 and the second channel 202 are located at different positions. When the humidifying component 500 is repaired or replaced, there is no need to remove the second channel 202, which can improve the convenience of maintenance.

[0138] In some embodiments, the adjustment assembly 20 includes a cooling assembly 300, a humidifying assembly 500, and a heating assembly 400. The cooling assembly 300 can reduce the temperature of the air flowing through the first channel 201, the heating assembly 400 can increase the temperature of the air flowing out of the second channel 202, and the humidifying assembly 500 can increase the humidity of the air flowing out of the second channel 202. In this way, the storage box 10 not only has two temperature adjustment modes with high temperature adjustment accuracy, but also can adjust humidity. In this case, the storage box 10 can be used for storing items such as cigars, which have high storage requirements for both temperature and humidity.

[0139] Reference Figure 5In some embodiments, the air circulation assembly 200 further includes a decorative plate 210, a rear cover 230, and a back plate 240. The decorative plate 210, the front cover 220, the rear cover 230, and the back plate 240 are sequentially arranged along the thickness direction of the box body 100.

[0140] 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.

[0141] 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 .

[0142] 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.

[0143] 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.

[0144] Reference Figure 5 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 .

[0145] 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.

[0146] 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.

[0147] 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.

[0148] Reference Figure 5 In some embodiments, the rear cover 230 further has an auxiliary channel 209 . The auxiliary channel 209 is formed at the lower portion of the rear cover 230 and passes through the lower portion of the front cover 220 .

[0149] First, the airflow in the storage chamber 101 enters the auxiliary channel 209 under the action of the fan 250. Then, the airflow enters the first channel 201 to perform airflow circulation.

[0150] Reference Figure 6 In some embodiments, the decorative panel 210 has the aforementioned air outlet 204 , the first air return outlet 205 , and the second air return outlet 206 .

[0151] 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.

[0152] 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.

[0153] 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.

[0154] 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.

[0155] 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 .

[0156] 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.

[0157] Reference Figure 6 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 .

[0158] 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.

[0159] Reference Figure 7 In some embodiments of the present application, the airflow circulation assembly 200 further includes a first guide structure 260 . The first guide structure 260 includes a first guide plate 264 , a second guide plate 265 , and a third guide plate 266 . The third guide plate 266 is located between the first guide plate 264 and the second guide plate 265 .

[0160] Among them, the second guide plate 265 and the first guide plate 264 jointly form a mixing guide channel 261, and the mixing guide channel 261 is connected to the upstream of the air mixing channel 203; the first guide channel 262 is formed between the third guide plate 266 and the first guide plate 264, and the first guide channel 262 is connected to the downstream of the first channel 201 and the upstream of the mixing guide channel 261; the second guide channel 263 is formed between the third guide plate 266 and the second guide plate 265, and the second guide channel 263 is connected to the downstream of the second channel 202 and the upstream of the mixing guide channel 261.

[0161] In this way, the first guide structure 260 can form a first guide channel 262 connected to the first channel 201, a second guide channel 263 connected to the second channel 202, and a mixing guide channel 261 connected to the air mixing channel input port 203a, thereby realizing the converging effect and preliminary mixing effect of the first guide structure 260.

[0162] In some embodiments, along the flow direction of the air mixing channel 203 , the length of the first guide plate 264 and the length of the second guide plate 265 are both greater than the length of the third guide plate 266 .

[0163] The longer first guide plate 264 and second guide plate 265 provide a longer path, allowing the airflow from the first channel 201 more time and space for preliminary mixing before entering the mixing guide channel 261. The shorter length reduces airflow resistance, ensuring smooth entry of the airflow into the mixing guide channel 261 and improving mixing efficiency.

[0164] 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.

[0165] 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.

[0166] 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.

[0167] 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.

[0168] 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.

[0169] 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.

[0170] In this way, the airflow passing through the first changing 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 and the second direction B are different, that is, they intersect, so the airflow flowing along the first direction A and the airflow flowing along the second direction B can be mixed.

[0171] By changing the flow direction, the disturbance and mixing effect of the airflow are increased, ensuring the uniformity and stability of the airflow, thereby improving the uniformity of the storage environment.

[0172] In some embodiments, the angle between the flow direction of the first direction-changing 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.

[0173] 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 located in the opposite direction of the second direction B, and the resistance between the flow direction of the first changing channel 271 and the flow direction of the air mixing channel 203 is large, thereby affecting the flow of air in the air mixing channel 203.

[0174] Reference Figure 8In some embodiments, the flow direction of the first direction-changing channel 271 is perpendicular to the flow direction of the air mixing channel 203. This means that the angle between the first direction A and the second direction B is a right angle. In this case, the contact area between the airflow passing through the first direction-changing channel 271 and the airflow not passing through the first direction-changing channel 271 is larger. This results in a higher degree of mixing between the airflow passing through the first direction-changing channel 271 and the airflow not passing through the first direction-changing channel 271, thereby enhancing the mixing effect of the air mixing channel 203 on the two airflows.

[0175] Reference Figure 9 In some embodiments, the second guide structure 270 is formed with a plurality of first direction-changing channels 271 , and the airflow directions of the plurality of first direction-changing channels 271 are different. That is, the airflow directions in each first direction-changing channel 271 are different.

[0176] Through the above arrangement, the airflow can be mixed between adjacent first direction-changing channels 271 , thereby improving the disturbance effect and mixing effect of the airflow.

[0177] Reference Figure 8 In some embodiments, the second guide structure 270 is formed with a plurality of first direction-changing channels 271 , and the airflow directions of the plurality of first direction-changing channels 271 are all the same. This means that the airflow directions within each first direction-changing channel 271 are all the same, ensuring that the second guide structure 270 can output airflow with a consistent flow path, thereby improving the uniformity and stability of the airflow.

[0178] In some embodiments, the first deflection plate 273 is configured to allow the airflow to flow in the first deflection channel 271 and change the Reynolds number of the airflow until the flow state of the airflow becomes turbulent.

[0179] It can be understood that if the flow state of the airflow is turbulent, that is, the airflow output from the first channel 201 and the airflow output from the second channel 202 flow in an irregular and chaotic manner, the two airflows are strongly mixed, so that the second guide structure 270 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.

[0180] In some embodiments, Re = ρvL0 / μ, where Re is the Reynolds number required for the airflow to become turbulent, ρ is the density of the airflow, v is the velocity of the airflow, L0 is the characteristic length required for the airflow to become turbulent, and μ is the dynamic viscosity of the airflow. As can be seen from the above, when conditions such as density, 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 airflow can be changed.

[0181] It is understood that when the Reynolds number of the airflow is low (e.g., less than 2000), the flow state of the airflow is generally laminar. Therefore, in order to transform the airflow into a turbulent state in the first redirecting channel 271, the Reynolds number of the airflow needs to be increased.

[0182] For example, if the Reynolds number of the airflow reaches 2300, i.e., Re = 2300, turbulence can be effectively induced. In this example, assuming v = 6 m / s, μ = 0.0000179 Pa.s, and ρ = 1.29, L0 = 5.3 mm. In other words, if the extension length of the first deflector plate 273 is 5.3 mm, turbulence can be induced, thereby improving the mixing of the airflow.

[0183] It should be noted that the above data are only examples and can be adjusted according to actual conditions.

[0184] In some embodiments, the actual extension length of the first deflection plate 273 is L, and the relationship between L and L0 is: L0*0.4 <L<L0*1.6。

[0185] It can be understood that a reasonable ratio helps the airflow to complete the change of the airflow state in the first changing channel 271.

[0186] When the first deflector plate 273 is at the aforementioned ratio, it can effectively change the flow state of the airflow, causing it to become turbulent, thereby improving the mixing of the airflow. If L is less than the aforementioned ratio, the first deflector plate 273 is too short, failing to increase the Reynolds number of the airflow and thus failing to induce turbulence. If L is greater than the aforementioned ratio, the first deflector plate 273 is too long, increasing the flow resistance of the airflow and thus affecting the flow of air in the first deflection channel 271.

[0187] In some embodiments, the relationship between L and L0 is: L0*0.5≤L≤L0*1.5. In this case, L0 can be an integer. Based on this, L can be half of L0. In this case, while achieving turbulent flow, it is easy to process the first deflector plate 273 with an integer length, thereby reducing the production and assembly precision of the first deflector plate 273.

[0188] In some embodiments, the first deflection plate 273 can have any shape. For example, the first deflection plate 273 can be a plate or a column. In another example, the end surface of the first deflection plate 273 can be circular, rectangular, or rounded rectangular.

[0189] It is understood that the aforementioned second angle refers to the angle between the flow direction of the first direction-changing 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 second angle has been described above and will not be repeated here.

[0190] Reference Figure 8 In some embodiments, when the surfaces of the multiple first deflection plates 273 extend in the same direction, the flow directions of the multiple first deflection channels 271 are all the same. This means that the airflow directions within each first deflection channel 271 are all the same, ensuring that the second guide structure 270 can output airflow with a consistent flow path, thereby improving the uniformity and stability of the airflow.

[0191] Reference 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, the distance between two adjacent first deflection plates 273 is S1, and the relationship between L and S1 is: L <S1<L*5。

[0192] It should be noted that the distance S1 may affect the size of the flow space between two adjacent first deflection plates 273 .

[0193] It is understood that a reasonable distance S1 facilitates sufficient mixing of airflow between adjacent first deflection plates 273, thereby improving mixing efficiency. If S1 is less than the aforementioned ratio, the distance between two adjacent first deflection plates 273 is too small, potentially preventing airflow from smoothly entering the first deflection channel 271, thereby affecting airflow. If S1 is greater than the aforementioned ratio, the distance between two adjacent first deflection plates 273 is too large, resulting in a low velocity of airflow entering the first deflection channel 271, thereby affecting the Reynolds number of the airflow and preventing the airflow from changing its flow state.

[0194] Reference Figure 10 In some embodiments, along the surface extension direction of the first turning plate 273 , the length of the first turning plate 273 is L, the distance between two adjacent first turning plates 273 is S1, and the relationship between L and S1 is: L*2≤S1≤L*4.

[0195] If S1 is between one times L and two times L, although the flow state of the airflow can be changed, the flow path of the airflow is short, and it is possible that only the flow state of part of the airflow is changed; if S1 is between four times L and five times L, although the flow path of the airflow is sufficient to ensure that the flow state of the entire airflow is changed, there is also the possibility that the airflow cannot smoothly enter the second changing channel 272.

[0196] In some embodiments, the second guide structure 270 is formed with a second turning channel 272, which is located downstream of the first turning channel 271. The flow direction of the second turning channel 272 is the same as the flow direction of the air mixing channel 203, that is, the airflow passing through the second turning channel 272 also flows in the second direction B. In this way, when the first turning channel 271 outputs airflow, the second turning channel 272 can change the airflow output by the first turning channel 271 and remix it. At the same time, the second turning channel 272 can provide a guiding effect to improve the uniformity of the airflow, ensuring that the air mixing channel 203 can output a highly mixed and uniform airflow.

[0197] Reference Figure 10 In some embodiments, the second guide structure 270 further includes a second deflection plate 274, which is located at the output port of the first deflection plate 273. There are multiple second deflection plates 274, which are arranged at intervals in the air mixing channel 203, and a second deflection channel 272 is formed between two adjacent second deflection plates 274; the surface extension direction of the second deflection plate 274 is the same as the flow direction of the air mixing channel 203.

[0198] In some embodiments, the second deflection plate 274 is configured to allow the airflow to flow in the second deflection channel 272 and change the Reynolds number of the airflow until the flow state of the airflow changes from turbulent flow to laminar flow.

[0199] It is understood that, based on the above, when the Reynolds number of the airflow is low (e.g., less than 2000), the flow state of the airflow is generally laminar. Therefore, in order to transform the airflow into a laminar state in the second redirecting channel 272, the Reynolds number of the airflow needs to be reduced.

[0200] It can be understood that if the flow state of the airflow is laminar, it means that the second changing channel 274 can receive the airflow output by the first changing channel 273 and flow in a parallel path to improve the flow consistency of the airflow in the mixing channel 203, thereby ensuring the uniformity and stability of the airflow output to improve the uniformity of the storage environment.

[0201] For example, the extension length of the second deflection plate 274 is shorter than the extension direction of the first deflection plate 273 , which can effectively reduce the Reynolds number of the airflow.

[0202] In another exemplary embodiment, no structure is provided between the second deflector plate 274 and the first deflector plate 273, that is, the airflow enters the mixing channel 203 after passing through the first deflector channel 271. Because the maximum aperture of the mixing channel 203 that allows airflow is much larger than the maximum aperture of the first deflector channel 271, the density of the airflow decreases rapidly, which can also reduce the Reynolds number of the airflow.

[0203] Reference Figure 10 In some embodiments, when the surface extension direction of the first deflection plate 273 is perpendicular to the flow direction of the air mixing channel 203, the minimum distance between adjacent first deflection plates 273 and second deflection plates 274 is S2, and the relationship between L and S2 is: L <S2<L*6。

[0204] It should be noted that the distance S2 may affect the flow space between the first turning plate 273 and the second turning plate 274 .

[0205] It is understood that a reasonable distance S2 helps the airflow change its flow state between the first deflection plate 273 and the second deflection plate 274. If S2 is less than the aforementioned ratio, the distance between the first deflection plate 273 and the second deflection plate 274 is too small, and the flow state of the airflow cannot be effectively changed, thereby failing to achieve laminar airflow output. If S2 is greater than the aforementioned ratio, the distance between the first deflection plate 273 and the second deflection plate 274 is too large, which may prevent the airflow from smoothly entering the second deflection channel 272, thereby affecting the flow of the airflow.

[0206] In some embodiments, along the flow direction of the air mixing channel 203 , the distance between adjacent first deflection plates 273 and second deflection plates 274 is S2 , and the relationship between L and S2 is: L*2≤S2≤L*5.

[0207] If S2 is between one times L and two times L, although the flow state of the airflow can be changed, the flow path of the airflow is short, and it is possible that only the flow state of part of the airflow is changed; if S1 is between five times L and six times L, although the flow path of the airflow is sufficient to ensure that the flow state of all the airflow is changed, there is also the possibility that the airflow cannot smoothly enter the second changing channel 272.

[0208] It is understood that when the airflow circulation assembly 200 includes the first guide structure 260 and the second guide structure 270, the airflow process is as follows:

[0209] First, under the influence of the fan 250, the airflow within the storage chamber 101 passes through the input port of the first channel 201 and the input port of the second channel 202, respectively, into the first channel 201 and the second channel 202. The airflow within the first channel 201 then passes through the first guide channel 262 and enters the mixing guide channel 261. Simultaneously, the airflow within the second channel 202 passes through the second guide channel 263 and enters the mixing guide channel 261. The first guide structure 260 then redirects the airflow for preliminary mixing, and the airflow is then output to the air mixing channel input port 203a. The airflow then passes through the first deflection channel 271, where its direction is changed and the airflow is further mixed. The airflow then passes through the second deflection channel 272, or briefly through the air mixing channel before passing through the second deflection channel 272. The second deflection channel 272 directs the airflow to the air mixing channel output port 203b. Finally, the airflow passes through the air mixing channel output port 203b and enters the storage chamber 101, completing the airflow cycle.

[0210] Reference Figure 8 In some embodiments, the air circulation assembly 200 further includes a third guide structure 280, which is connected to the air mixing channel output port 203b, and the aperture of the output port of the third guide structure 280 is larger than the aperture of the air mixing channel output port 203b.

[0211] By increasing the aperture of the output port, the velocity of the air flow can be reduced, soft air flow can be achieved, and the air flow circulation in the storage cavity 101 can be ensured to be relatively stable and uniform.

[0212] Reference Figure 8 In 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.

[0213] 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.

[0214] 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.

[0215] 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 .

[0216] 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.

[0217] 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.

[0218] 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.

[0219] Soft air flow can reduce direct impact on stored items and protect the integrity of stored items.

[0220] 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.

[0221] When the aperture of the output port of the second outlet channel 282 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.

[0222] Soft air flow can reduce direct impact on stored items and protect the integrity of stored items.

[0223] It is understandable that if the aforementioned ratio is too small, the aperture of the air mixing channel outlet 203b cannot be effectively increased, the air output cannot meet the standard of soft air output, and thus the soft air output cannot be effectively achieved.

[0224] Reference Figure 4In some embodiments, the first outlet channel 281 and the second outlet channel 282 can be located at different positions within the storage chamber 101. For example, the first outlet channel 281 can be located above the second outlet channel 282; for example, the first outlet channel 281 can be located below the second outlet channel 282. The lower channel is closer to the items in the storage chamber 101 than the upper channel.

[0225] In some embodiments, the aperture of the output port of the first outlet channel 281 is larger than the aperture of the output port of the second outlet channel 282 , and the first outlet channel 281 is located below the second outlet channel 282 .

[0226] Through the above setting, the first outlet channel 281 is close to the items in the storage cavity 101 and has a larger output port aperture, which can ensure that the airflow will significantly reduce the flow rate when output to achieve soft air outlet and ensure that the airflow circulation in the storage cavity 101 is relatively stable and uniform.

[0227] Reference Figure 4 In some embodiments, when the aforementioned third guide structure 280 is provided 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 is connected to the first outlet channel 281, and the second air outlet 208 is connected to the second outlet channel 282.

[0228] Reference Figure 5 In some embodiments, when the aforementioned third guide structure 280 is provided 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 is connected to the first outlet channel 281, and the second air outlet 208 is connected to the second outlet channel 282.

[0229] Reference Figure 11 In some embodiments, the airflow circulation assembly 200 includes the aforementioned decorative panel 210, front cover 220, rear cover 230, and rear panel 240. Two second channels 202B are formed between the decorative panel 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 output ports of the two second channels 202B are connected. A first channel 201 is formed between the front cover 220 and the rear cover 210. The decorative panel 210 has a first return air port 205 corresponding to the first channel 201 and two second return air ports 206 corresponding to the two second channels 202B.

[0230] The first air return port 205 is connected to the middle position of the lower portion of the storage chamber 101. The first air return port 205 can be connected to the auxiliary channel 209.

[0231] First, part of the airflow a1 in the storage chamber 101 enters the auxiliary channel 209 through the first return air port 205 . After filling the return air chamber 231 between the front cover 220 and the rear cover 230 , the airflow a1 enters the first channel 201 .

[0232] Reference Figure 12 Refrigeration assembly 270 includes an evaporator 310, located near the input port of first channel 201. Evaporator 310 cools and dehumidifies the airflow. A second fan 252 is provided on the output side of evaporator 310. Second fan 252 is a centrifugal fan that draws airflow from evaporator 271 and directs it to air mixing channel 203.

[0233] The second air return port 206 is connected to both sides of the lower portion of the storage chamber 101 and is connected to the output side of the humidifying assembly 500. The humidifying assembly 500 can output a humidified air flow a3 through the second air return port 206 and enter the second channel 202B.

[0234] At the same time, another portion of the airflow a2 in the storage chamber 101 and the humidified airflow a3 output by the humidification assembly 500 pass through the second return air port 206 and enter the two first channels 201. Each of the two first channels 201 is equipped with a first fan 251. The first fan 251 is an axial fan that directs the airflow into the air mixing channel 203.

[0235] The two heating assemblies 400 are located near the outlets of the two second channels 202B to increase the temperature of the airflow flowing through the two second channels 202B. In this way, the first channel 201 outputs a cooled and dehumidified airflow a4, while the second channel 202B outputs a heated and humidified airflow a5.

[0236] Then, the two airflows respectively enter the first guide channel 262 and the second guide channel 263 formed by the first guide structure 260 . The two airflows change in flow rate and are preliminarily mixed in the mixing guide channel 261 .

[0237] Then, the second guide structure 270 receives the airflow output by the first guide structure 270 and passes through the first changing channel 271. The adjacent first changing plate 273 forms the first changing channel 271. The first changing plate 273 can change the Reynolds number of the airflow to change the airflow from a laminar state to a turbulent state, thereby enhancing the degree of mixing of the two airflows. The airflow output by the first changing channel 271 briefly enters the air mixing channel 203 and then enters the second changing channel 272 of the second guide structure 270. The adjacent second changing plate 274 forms the second changing channel 272. The second changing plate 274 can change the airflow from a turbulent state to a laminar state.

[0238] Then, the third guide structure 280 receives the airflow a6 output from the second redirecting channel 272. The third guide structure 280 forms a first outlet channel 281 and a second outlet channel 282. The calibers of the output ports of the first outlet channel 281 and the second outlet channel 282 are both increased, which can achieve a soft outlet of the airflow. The output port of the first outlet channel 281 is located above the output port of the second outlet channel 282. The output port of the first outlet channel 281 is connected to the first air outlet 207, and the airflow a7 enters the storage chamber 101 via the first air outlet 207. The output port of the second outlet channel 282 is connected to the second air outlet 208, and the airflow a8 enters the storage chamber 101 via the first air outlet 207.

[0239] Then, in the air mixing channel 203 of the air circulation component 200 , the physical parameters of the airflow output by 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 .

[0240] The fluctuations in physical parameters between the airflows a7 and a8 received by the storage chamber 101 and the airflows a1 and a2 released are minimal. Thus, while the airflow flow time remains constant, the physical parameters of the airflow undergo multiple changes. Compared to a single change, the adjustment accuracy of the physical parameters is increased, which can reduce the deviation between the actual airflow and the target airflow, facilitating the creation of storage conditions with constant physical parameters. This allows the airflow within the storage chamber 101 to remain within a preset range, thus facilitating item storage.
