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 cycle of items, especially for items with more stringent environmental conditions, such as fresh food, cigars, alcoholic beverages, etc.

[0003] In the related art, in order to maintain storage for a long time and to ensure relatively constant storage conditions, people have invented a storage cavity, by setting a heater, a heat exchanger, etc. in the storage cavity, and adjusting the operation of the heater, the heat exchanger and other electrical components to adjust the storage temperature of the storage cavity. For example, a warm air channel is provided in the storage cabinet to increase the temperature of the storage cavity. However, constant temperature can no longer meet people's storage needs for high-demand items, and more constant conditions such as humidity need to be introduced.

[0004] However, in a storage cabinet with multi-type channel delivery, different types of airflows are delivered in sequence, the airflows cannot be well integrated, and the mixing effect is poor, which is not conducive to the storage of the storage box. Summary of the invention

[0005] Some embodiments of the present application provide a storage box that can improve the mixing efficiency of airflow. The error between the airflow received by the storage cavity and the target airflow is small, and high-precision temperature and humidity adjustment can be achieved, which is conducive to forming storage conditions with constant physical parameters, thereby facilitating the storage of items.

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

[0007] A box body having a cavity;

[0008] An inner liner is located in the cavity, and the inner liner forms a storage cavity;

[0009] An air circulation component is located in the storage cavity; the air circulation component has:

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

[0011] a second channel, wherein an input port of the second channel is connected to the storage cavity;

[0012] The air mixing channel has:

[0013] An input port of the air mixing channel is connected to an output port of the first channel and an output port of the second channel;

[0014] An air mixing channel output port connected to the storage chamber;

[0015] a fan, located in at least one of the air mixing channel, the first channel and the second channel, and used to drive the air flow;

[0016] A first guide structure is located at the connection point between the first channel, the second channel and the air mixing channel, and is used to receive the airflow input from the first channel and the second channel and change the flow direction so as to output after mixing;

[0017] a second guide structure, located in the air mixing channel and downstream of the first guide structure, for receiving the airflow output by the first guide structure and changing the flow direction so as to output the airflow to the output port of the air mixing channel after mixing;

[0018] The adjustment component is located in at least one of the first channel and the second channel, and is used to change the physical parameters of the airflow flowing through the first channel so that the physical parameters of the first channel are different from the physical parameters of the second channel.

[0019] Some embodiments of the present application provide a storage box, the storage box has a storage cavity and an airflow circulation component connected to the storage cavity, the airflow circulation component receives the airflow of the storage cavity through the first channel and the second channel, adjusts the physical parameters (temperature, humidity, etc.) of the airflow in the first channel and the second channel through the adjustment component, receives the airflow output from the first channel and the second channel through the first guide structure in the air mixing channel and performs preliminary mixing, and changes the flow direction of the airflow after preliminary mixing through the second guide structure. Under the action of the first guide structure, the flow directions of the two airflows with different physical parameters change, and the contact area between the two airflows increases; compared with the scheme in the related art, the mixing efficiency is improved. Then, under the action of the second guide structure, the flow direction of the airflow after preliminary mixing changes again, and the mixing efficiency is improved again. Therefore, through the above-mentioned setting, in the airflow circulation between the storage cavity and the airflow circulation component, the airflow changes its flow direction multiple times in the air mixing channel, that is, multiple mixing processes are performed, and it has a higher mixing efficiency.

[0020] Compared with the related art, the airflow received by the storage cavity in this embodiment has a higher mixing efficiency. In this way, the error between the airflow received by the storage cavity and the target airflow is small, and a higher precision of temperature adjustment and humidity adjustment can be achieved, which is conducive to forming a storage condition with constant physical parameters, thereby facilitating the storage of items.

[0021] In some embodiments of the present application, the first guide structure is configured to change the airflow passing through at a first angle, and the second guide structure is configured to change the airflow passing through at a second angle;

[0022] The first angle is smaller than the second angle.

[0023] In this arrangement, if the first angle is greater than 90°, the first channel and the second channel cannot converge, and thus the mixing effect of the first guide structure cannot be achieved; when the second angle is greater than 90°, the flow direction of the second guide structure is opposite to the flow direction of the airflow derived from the first guide structure, and the mixing effect of the second guide structure cannot be achieved.

[0024] In some embodiments of the present application, the value range of the first angle is less than 90°, and the value range of the second angle is less than or equal to 90°.

[0025] With this arrangement, a smaller angle makes it easier for the airflow to change direction, avoiding stagnation or turbulence of the airflow in the first guide structure and maintaining good fluidity; through large-angle flow direction changes, the airflow is mixed multiple times on the basis of preliminary mixing, ensuring the uniformity and stability of the airflow.

[0026] In some embodiments of the present application, the first guiding structure includes:

[0027] a first guide plate;

[0028] a second guide plate, forming a mixing guide channel together with the first guide plate, wherein the mixing guide channel is connected to the upstream of the air mixing channel;

[0029] 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 a downstream of the first channel and an upstream of the mixing guide channel;

[0030] 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;

[0031] The airflow velocity received by the mixing guide channel is smaller than the airflow velocity output by the first guide channel and the airflow velocity output by the second guide channel.

[0032] With such 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.

[0033] In some embodiments of the present application, the middle portions of the first guide plate and the second guide plate both protrude in a direction toward the third guide plate, and the third guide plate protrudes in a direction toward the second guide plate;

[0034] An inlet is arranged at a protruding position of the third guide plate, and the inlet is used to connect the mixing guide channel, the first guide channel and the second guide channel.

[0035] Such arrangement increases the airflow contact area through the arc design and bulge, reduces resistance and vortex, and improves mixing efficiency. Through the inlet, two airflows can be mixed at the initial stage of converging, thereby improving mixing efficiency.

[0036] In some embodiments of the present application, along the flow direction of the air mixing channel, the length of the first guide plate and the length of the second guide plate are both greater than the length of the third guide plate.

[0037] In this way, the longer first guide plate and the second guide plate have a longer path, so that the airflow from the first channel has more time and space for preliminary mixing before entering the mixing guide channel. The shorter length can reduce the resistance of the airflow, ensure that the airflow can smoothly enter the mixing guide channel, and improve the mixing efficiency.

[0038] In some embodiments of the present application, the second guiding structure includes:

[0039] 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;

[0040] There are multiple first deflection plates, and the multiple first deflection plates are arranged at intervals in the air mixing channel;

[0041] 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;

[0042] The first deflection plate is configured to make the airflow flow in the first deflection channel and change the Reynolds number of the airflow until the flow state of the airflow becomes turbulent.

[0043] With such arrangement, the flow state of the airflow is turbulent, the airflow output from the first channel and the airflow output from the second channel flow in an irregular and chaotic manner, and 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.

[0044] In some embodiments of the present application, according to Re=ρvL0 / μ, Re is the Reynolds number required for the flow state of the airflow to be turbulent, is the density of the airflow, v is the flow velocity of the airflow, L0 is the characteristic length required for the flow state of the airflow to become turbulent, and μ is the dynamic viscosity of the airflow;

[0045] The actual extension length of the first deflection plate is L, and the relationship between L and L0 is: L0*0.4 <L<L0*1.6。

[0046] With such arrangement, a reasonable ratio helps the airflow to complete the change of the airflow state in the first redirection channel.

[0047] In some embodiments of the present application, the second guide structure further includes:

[0048] 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.

[0049] 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;

[0050] The second deflection plate is configured to make the airflow 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.

[0051] With such a configuration, if the flow state of the airflow is laminar flow, 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 mixing channel, thereby ensuring the uniformity and stability of the airflow output to improve the uniformity of the storage environment.

[0052] In some embodiments of the present application, the surfaces of the plurality of first deflection plates extend in the same direction;

[0053] The distance between two adjacent first deflection plates is S1, and the relationship between L and S1 is: <S1<L*5;

[0054] and / or,

[0055] The surface extension direction of the first deflection plate is perpendicular to the flow direction of the air mixing channel;

[0056] The minimum distance between the adjacent first deflection plate and the second deflection plate is S2, and the relationship between L and S2 is: L <S2<L*6。

[0057] In this way, a reasonable distance S1 helps the airflow to be fully mixed between adjacent first deflection plates, thereby improving the mixing efficiency. A reasonable distance S2 helps the airflow to change its flow state between the first deflection plate and the second deflection plate.

[0058] In some embodiments of the present application, the surfaces of the plurality of first deflection plates extend in different directions.

[0059] With such an arrangement, the airflow can be mixed between adjacent first direction-changing channels, thereby improving the disturbance effect and mixing effect of the airflow.

[0060] In some embodiments of the present application, the angle between the surface extension direction of the first deflection plate and the flow direction of the air mixing channel is an acute angle.

[0061] In this arrangement, if the angle between the first direction and the second direction is an obtuse angle, the first direction is located in the opposite direction of the second direction, and the resistance between the flow direction of the first changing channel and the flow direction of the air mixing channel is relatively large, thereby affecting the flow of air in the air mixing channel.

[0062] In some embodiments of the present application, the airflow circulation component further includes:

[0063] The third guide structure is connected to the output port of the air mixing channel, and the aperture of the output port of the third guide structure is larger than the aperture of the output port of the air mixing channel.

[0064] With such a configuration, 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 can be ensured to be relatively stable and uniform.

[0065] In some embodiments of the present application, the third guide structure includes:

[0066] A first outlet section is formed with a first outlet channel, the first outlet channel is connected to the outlet of the air mixing channel, and the aperture of the outlet of the first outlet channel is larger than the aperture of the outlet of the air mixing channel;

[0067] 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,

[0068] 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.

[0069] With such arrangement, the storage box can adjust the positions of the first outlet channel and the second outlet channel according to the stored items to match the items with different needs, thereby achieving adaptive and gentle air outlet.

[0070] In some embodiments of the present application, the ratio between the aperture of the output port of the first outlet channel and the aperture of the output port of the air mixing channel is greater than or equal to 3.

[0071] In this way, when the aperture of the outlet of the first outlet channel is 3 times or more than the aperture of the outlet of the air mixing channel, the airflow will significantly reduce the flow rate when it is output to achieve soft air discharge, ensuring that the airflow circulation in the storage cavity is relatively stable and uniform. Soft air discharge can reduce the direct impact on the stored items and protect the integrity of the stored items.

[0072] In some embodiments of the present application, the ratio of the aperture of the output port of the second outlet channel to the aperture of the output port of the air mixing channel is greater than or equal to 3.

[0073] In this way, when the aperture of the outlet of the second outlet channel is 3 times or more than the aperture of the outlet of the air mixing channel, the airflow will significantly reduce the flow rate when it is output to achieve soft air discharge, ensuring that the airflow circulation in the storage cavity is relatively stable and uniform. Soft air discharge can reduce the direct impact on the stored items and protect the integrity of the stored items.

[0074] In some embodiments of the present application, the airflow circulation component further includes:

[0075] Decorative panels;

[0076] a front cover, located at a side of the decorative plate away from the storage cavity, wherein at least a portion of the second channel is formed between the front cover and the decorative plate;

[0077] A rear cover, located at a side of the front cover away from the storage cavity, and the air mixing channel is formed between the rear cover and the front cover;

[0078] A back plate is located on a side of the rear cover away from the storage cavity, and the first channel is formed between the back plate and the rear cover.

[0079] With such arrangement, the decorative panel, the front cover, the rear cover and the back plate can be sequentially stacked and connected to form the aforementioned first channel, the second channel and the air mixing channel, thereby forming an air circulation between the storage cavity and the air circulation component.

[0080] In some embodiments of the present application, the decorative plate has:

[0081] an air outlet, located at the upper portion of the decorative plate, connected to the air mixing channel output port, and connected to the upper portion of the storage cavity;

[0082] a first air return port, located at the lower portion of the decorative plate, connected to the input port of the first channel and connected to the lower portion of the storage cavity;

[0083] a second air return port, located at a lower portion of the decorative plate, connected to an input port of the second channel and connected to a lower portion of the storage cavity;

[0084] The first air return port and the second air return port are respectively connected to different positions of the lower part of the storage cavity.

[0085] With this arrangement, part of the airflow can enter the first channel through the first return air outlet, and the other part of the airflow can enter the second channel through the second return air outlet. The airflow can be divided into two streams and flow simultaneously. The overall flow speed of the airflow is increased, which can meet the customer's needs for rapid adjustment.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0126] The following will be combined with the drawings in some embodiments of the present application to clearly and completely describe the technical solutions in some embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0127] In the related art, such as the constant temperature and humidity cigar cabinet and its control method disclosed in Chinese patent CN108273572A, the air passes through the first area of ​​the heated airflow and the second area of ​​the cooled airflow in sequence, and the first area can also be connected to a humidifying device to achieve temperature and humidity regulation. The heated airflow and the humidified airflow pass through the second area, and the cooling process and the mixing process of multiple airflows occur simultaneously. In this case, the airflow mixing process is completed only through the flow of the airflow itself, and the mixing efficiency is poor, and thus the precise adjustment of temperature and humidity cannot be achieved, so that the actual storage environment is too different from the environment required for the items.

[0128] In view of this, some embodiments of the present application provide a storage box, which has a storage cavity and an airflow circulation component connected to the storage cavity, the airflow circulation component receives the airflow of the storage cavity through the first channel and the second channel, adjusts the physical parameters (temperature, humidity, etc.) of the airflow in the first channel and the second channel through the adjustment component, receives the airflow output from the first channel and the second channel through the first guide structure in the air mixing channel and performs preliminary mixing, and changes the flow direction of the airflow after preliminary mixing through the second guide structure. In this way, under the action of the first guide structure, the flow directions of the two airflows with different physical parameters change, and the mixing efficiency is improved compared with the scheme in the related art. Then, under the action of the second guide structure, the flow direction of the airflow after preliminary mixing changes again, and the mixing efficiency is improved again. Therefore, through the above-mentioned setting, in the airflow circulation between the storage cavity and the airflow circulation component, the airflow changes its flow direction multiple times in the air mixing channel, that is, multiple mixing processes are performed, and it has a higher mixing efficiency.

[0129] Compared with the related art, the airflow received by the storage cavity in this embodiment has a higher mixing efficiency. In this way, the error between the airflow received by the storage cavity and the target airflow is small, and a higher precision of temperature adjustment and humidity adjustment can be achieved, which is conducive to forming a storage condition with constant physical parameters, thereby facilitating the storage of items.

[0130] In this application, it should be understood that the terms involved have the following meanings:

[0131] Ventilation volume: the volume of air passing through a certain section per unit time.

[0132] Venturi effect: According to the fluid continuity equation and Bernoulli equation, when a fluid flows through a contracting pipe, its kinetic energy increases due to the increase in the flow velocity of the fluid, while the pressure energy decreases accordingly. This means that in the narrow part of the contracting pipe, the fluid velocity is the highest and the pressure is the lowest.

[0133] Preset range: Adapt to the storage conditions of the stored items.

[0134] Laminar flow: refers to the flow of fluid particles in parallel paths or layers without mixing with each other.

[0135] Turbulence: refers to the flow of fluid particles in an irregular and chaotic manner, with intense mixing and vortexing occurring within the fluid.

The input port of the first channel 201 is connected to 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 airflow in the storage cavity 101.

[0149] In some embodiments, the airflow circulation component 200 has a second channel 202, which is used to transport 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 is connected to 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 airflow in the storage cavity 101.

[0150] 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.

[0151] It can be understood that the first channel 201 and the second channel 202 form an airflow respectively, so that the two airflows enter the air mixing channel 203 and are mixed in 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.

[0152] 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 .

[0153] In some embodiments, the airflow circulation assembly 200 includes a fan 250 , which is used to drive the airflow.

[0154] It is understandable that the fan 250 may be an axial fan, and the airflow flows along the axial direction of the fan blades under the action of the axial fan. The fan 250 may also be a centrifugal fan, and the airflow flows along the radial direction of the fan blades under the action of the centrifugal fan. The fan 250 may also be a mixed flow fan, and under the action of the mixed flow fan, part of the airflow flows along the axial direction of the fan blades, and the other part flows along the radial direction of the fan blades.

[0155] 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.

[0156] In some embodiments, the number of fans 250 can be adjusted according to actual conditions.

[0157] Reference Figure 4 In some embodiments, the fan 250 includes a first fan 251 and a second fan 252. The first fan 251 is located in the first channel 201, and the second fan 252 is located in the second channel 202. The first fan 251 is used to drive the airflow in the first channel 201 to flow to the air mixing channel 203, and the second fan 252 is used to drive the airflow in the second channel 202 to flow to the air mixing channel 203. In this way, multiple fans 250 work simultaneously, which can increase the airflow circulation speed between the storage cavity 101 and the airflow circulation component 200.

[0158] Reference Figure 5 In some embodiments, the airflow circulation component 200 includes an adjustment component 20 for changing the physical parameters of the airflow passing therethrough. The physical parameters include but are not limited to the aforementioned temperature, humidity, oxygen content, etc.

[0159] 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.

[0160] It should be noted that the shapes, positions, and compositions 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 the two parts are not adjacent in position but have airflow.

[0161] It is understandable that after one of the airflows passes through one of the first channel 201 and the second channel 202 and undergoes a change in physical parameters, it is mixed with the other airflow in the air mixing channel 203 and the physical parameters will change. That is, the physical parameters of the airflow in the air mixing channel 203 are different from the physical parameters of the airflow in the first channel 201 and the physical parameters of the airflow in the second channel 202, and thus the physical parameters of the airflow in the air mixing channel 203 are also different from the physical parameters of the airflow in the storage chamber 101.

[0162] Taking the physical parameter as temperature, for example, the air flow temperature in the storage chamber 101 is 0° C., the air flow temperature in the first channel 201 changes to −2° C., and the air flow temperature in the second channel 202 does not change.

[0163] The airflow in the storage box 10 is divided into two streams. After one stream enters the first channel 201, the airflow temperature drops to -2°C. After the other stream enters the second channel 202, the airflow temperature remains unchanged. The airflow in the first channel 201 and the airflow in the second channel 202 are mixed in the air mixing channel 203. In the air mixing channel 203, the 0°C airflow and the -2°C airflow are mixed, and the -1°C airflow is finally output from the air mixing channel 203. At this time, the physical parameters of the airflow in 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 storage chamber 101.

[0164] Taking physical parameters including temperature and humidity, the air flow temperature in the storage chamber 101 is 0°C and the humidity is 1g / m3, the air flow temperature through the first channel 201 changes to -2°C, and the humidity does not change; the air flow temperature through the second channel 202 does not change, and the humidity increases by 1g / m3.

[0165] The airflow in the storage box 10 is divided into two streams. After one stream enters the first channel 201, the airflow temperature drops to -2°C and the humidity remains unchanged. After the other stream enters the second channel 202, the airflow temperature remains unchanged and the humidity increases to 2g / m3. The airflow in the first channel 201 and the airflow in the second channel 202 are mixed in the air mixing channel 203. In the air mixing channel 203, the 0°C airflow is mixed with the -2°C airflow, and the air mixing channel 203 finally outputs the -1°C airflow; the 1g / m3 airflow is mixed with the 2g / m3 airflow, and the air mixing channel 203 finally outputs the 1.5g / m3 airflow. At this time, the physical parameters of the airflow in 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 storage chamber 101.

[0166] It can be known from the above contents that 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 .

[0167] In this way, during the process of the airflow in the storage box 10 entering the airflow circulation component 200 and circulating out, the physical parameters of the airflow released by the storage box 10 are closer to the physical parameters of the airflow received, and the fluctuation of the physical parameters is smaller.

[0168] Through the above arrangement, the fluctuation of the physical parameter change is small between the airflow received by the storage cavity 101 and the airflow released. In this way, the physical parameter of the airflow changes twice when the airflow flow time remains unchanged. Compared with a single change, the adjustment accuracy of the physical parameter is increased, which can reduce the deviation between the actual airflow and the target airflow, and is conducive to forming a storage condition with constant physical parameters, so that the airflow in the storage cavity 101 can be within a preset range, which is conducive to the storage of items.

[0169] Reference Figure 5 In some embodiments, when the physical parameter includes temperature, the adjustment component 20 includes a refrigeration component 300. The refrigeration component 300 is located in the first channel 201 and is used to reduce the temperature of the airflow flowing through the first channel 201 so that the air mixing channel 203 outputs a relatively low temperature airflow. The type of the refrigeration component 300 can be selected according to actual conditions.

[0170] 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 moisture in the air flow passing through, thereby absorbing heat to complete refrigeration while reducing the humidity of the air flow.

[0171] Reference Figure 6 In some embodiments, when the physical parameter includes temperature, the adjustment component 20 includes a heating component 400, which is located in the second channel 202 and is used to increase the temperature of the airflow flowing through the second channel 202 so that the air mixing channel 203 outputs a higher temperature airflow. The type of the heating component 400 can be selected according to actual conditions.

[0172] Reference Fig.10 In some embodiments, the heating assembly 400 includes a heater 410 and a protective cover 420 .

[0173] The protective cover 420 is disposed outside the heater 410 to protect the heater 410 from damage by the external environment and to prevent the high temperature of the heater 410 from causing harm to the surrounding environment and personnel. The protective cover 420 can improve the safety and durability of the system.

[0174] The protective cover 420 has a heat dissipation port. By providing the heat dissipation port, airflow can pass through the protective cover 420, thereby achieving heat dissipation and ventilation. The heat dissipation port can prevent the heater 410 from overheating, thereby improving the efficiency and life of the heater 410.

[0175] Reference Figure 7 In some embodiments, when the physical parameter includes humidity, the adjustment component 20 includes a humidifying component 500, which can increase the humidity of the airflow so that the air mixing channel 203 outputs an airflow with high humidity. The type of the humidifying component 500 can be selected according to actual conditions.

[0176] Reference Figure 7 In some embodiments, the humidifying component 500 is located in the second channel 202 to increase the humidity of the airflow passing through the second channel 202. That is, the humidifying component 500 is directly installed in the second channel 202. When the airflow passes through the second channel 202, the humidifying component 500 humidifies the airflow, thereby increasing the humidity of the airflow passing through the second channel 202.

[0177] Through the above configuration, the humidification component 500 can effectively humidify the airflow to ensure that the humidity of the airflow can reach the expected level at a relatively fast speed when passing through the second channel 202. In addition, the humidification component 500 and the second channel 202 are integrated into a whole, and the structure is relatively compact; in addition, the humidification component 500 can more accurately control the humidity of the airflow, reduce humidity fluctuations, and improve the humidity stability of the storage environment.

[0178] Reference Figure 8 In some embodiments, if the second channel 202 may include 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.

[0179] It should be noted that the second channel 202A and the second channel 202B can be connected in a variety of ways. Exemplarily, the second channel 202A and the second channel 202B are directly connected end to end. In another exemplary embodiment, the second channel 202A and the second channel 202B are both connected to the storage cavity 101, and the airflow in the storage cavity 101 and the airflow in the second channel 202A can enter the second channel 202B. In another exemplary embodiment, the second channel 202A is connected to the second channel 202B through a pipeline.

[0180] It should be noted that the first channel 201 may also include multiple parts, and the content thereof can refer to the second channel 202 including multiple connected parts, which will not be described in detail here.

[0181] In some embodiments, the second channel 202A and the second channel 202B are both connected to the storage chamber 101, and the airflow in the storage chamber 101 and the airflow in the second channel 202A can enter the second channel 202B. The humidification component 500 is located in the second channel 202A, and is used to provide humidified airflow to the second channel 202B. The airflow in the storage chamber 101 and the airflow in the second channel 202 can flow to the second channel 202A.

[0182] 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 disassemble the second channel 202, which can improve the convenience of maintenance.

[0183] Reference Figure 4 In some embodiments, when the physical parameter includes oxygen content, the adjustment component 20 includes an oxygen component 600, which is used to change the oxygen content of the air flow passing through so that the mixed air channel 203 outputs air flows with different oxygen contents for storing items that require oxygen.

[0184] The type of oxygen assembly 600 can be selected according to actual conditions.

[0185] Reference Fig. 9 It can be understood that the number of adjustment components 20 can be multiple.

[0186] In some embodiments, the adjustment component 20 includes a refrigeration component 300, a humidification component 500, and a heating component 400. The refrigeration component 300 can reduce the temperature of the airflow flowing through the first channel 201, the heating component 400 can increase the temperature of the airflow output from the second channel 202, and the humidification component 500 can increase the humidity of the airflow output from the second channel 202. In this way, the storage box 10 not only has two temperature adjustment methods, the temperature adjustment accuracy is high, and the humidity can be adjusted. At this time, the storage box 10 can be used for cigars and other items that have high storage requirements for temperature and humidity.

[0187] Reference Fig.10 In some embodiments, the airflow circulation assembly 200 further includes a decorative plate 210, a front cover 220, 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.

[0188] The front cover 220 is located on the side of the decorative plate 210 away from the storage cavity 101, and at least part of the second channel 202 is formed between the front cover 220 and the decorative plate 210. That is, part of the second channel 202 can be formed between the front cover 220 and the decorative plate 210, or all of the second channel 202 can be formed. The rear cover 230 is located on the side of the front cover 220 away from the storage cavity 101, and the air mixing channel 203 is formed between the rear cover 230 and the front cover 220. The back plate 240 is located on the side of the rear cover 230 away from the storage cavity 101, and the first channel 201 is formed between the back plate 240 and the rear cover 230.

[0189] It is understandable that the decorative plate 210 , the front cover 220 , the rear cover 230 and the back plate 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 .

[0190] In some embodiments, 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. Two second channels 202 are formed between the front cover 220 and the decorative plate 210, and the two second channels 202 are respectively arranged at the two side edges of the front cover 220. In addition, the first channel 201 and the two second channels 202 are all located at the lower part of the storage cavity 101. The air mixing channel 203 is located at the upper part of the storage cavity 101.

[0191] It can be understood that in the above structure, the airflow in the storage chamber 101 enters the first channel 201 and the two second channels 202 respectively, and then the airflow in the first channel 201 and the two second channels 202 enters the mixed air channel 203, and finally, the airflow in the mixed air channel 203 is output and enters the storage chamber 101, forming an airflow circulation between the storage chamber 101 and the air path circulation component 200.

[0192] Reference Fig.10 In some embodiments, referring to the above, 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 .

[0193] In some embodiments, the decorative plate 210 and the front cover 220 may form a second channel 202B together. At this time, the position of the second channel 202A may be selected according to actual conditions. Exemplarily, the second channel 202B is located at the lower part 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 side of the storage cavity 101.

[0194] In some embodiments, two second channels 202B are formed between the front cover 220 and the decorative plate 210, and the two second channels 202B are respectively disposed at the two side edges of the front cover 220. In addition, the first channel 201 and the two second channels 202B are both located at the lower part of the storage cavity 101. The air mixing channel 203 is located at the upper part of the storage cavity 101.

[0195] It can be understood that in the above structure, the airflow in the storage chamber 101 enters the first channel 201 and the two second channels 202B respectively, and then the airflow in the first channel 201 and the two second channels 202B enters the mixed air channel 203, and finally, the airflow in the mixed air channel 203 is output and enters the storage chamber 101, forming an airflow circulation between the storage chamber 101 and the air path circulation component 200.

[0196] Reference Fig.11 In some embodiments, the airflow circulation assembly 200 further includes a first guide structure 260, which is located at the connection point between the first channel 201, the second channel 202 and the air mixing channel 203. The first guide structure 260 is used to receive the airflow input from the first channel 201 and the second channel 202 and change the flow direction so as to output after mixing.

[0197] It is understandable that the first guide structure 260 can receive and change the flow direction of the airflow input from the first channel 201 and the second channel 202 to achieve the confluence of the two airflows. In this process, the flow direction of the two airflows is changed, and compared with the case where the flow direction is not changed, the contact area between the two airflows is increased, which can improve the degree of mixing; through the increase in the degree of mixing, if the flow time of the airflow is not changed, the mixing effect of the two airflows is improved, and the accuracy of airflow mixing can be improved; if the flow speed of the airflow is not changed, the time required for the two airflows to reach the mixing degree in the related art is reduced, and the efficiency of airflow mixing can be improved.

[0198] In some embodiments, the airflow circulation assembly 200 further includes a second guide structure 270. The second guide structure 270 is located in the air mixing channel 203 and downstream of the first guide structure 260. The second guide structure 270 is used to receive the airflow output by the first guide structure 260 and change the flow direction so as to output the airflow to the air mixing channel output port 203b after mixing.

[0199] It is understandable that the second guide structure 270 can receive and change the flow direction of the airflow output by the first guide structure 260. In this process, the flow direction of the airflow is changed again, and compared with the case where the flow direction is not changed, the contact area of ​​the airflow is increased, which can further improve the mixing degree.

[0200] By means of the airflow circulation component 200 provided with the first guide structure 260 and the second guide structure 270, the mixing degree of the airflow is increased, and the mixing efficiency and the mixing effect of the airflow are increased, so that the error between the airflow received by the storage cavity 101 and the target airflow is smaller, and higher-precision temperature and humidity adjustments can be achieved, which is conducive to forming storage conditions with constant physical parameters, thereby facilitating the storage of items.

[0201] It can be 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:

[0202] First, under the influence of the fan 250, the airflow in the storage chamber 101 passes through the input port of the first channel 201 and the input port of the second channel 202 to enter the first channel 201 and the second channel 202 respectively. Then, the airflow in the first channel 201 passes through the first guide channel 262 to enter the mixing guide channel 261, and at the same time, the airflow in the second channel 202 passes through the second guide channel 263 to enter the mixing guide channel 261. Then, the first guide structure 260 changes the direction of the airflow for preliminary mixing and outputs it to the input port 203a of the mixing channel. Then, the airflow passes through the first deflection channel 271, the direction of the airflow changes, and the airflow is mixed again. Then, the airflow passes through the second deflection channel 272 or passes through a short mixing channel and then passes through the second deflection channel 272. The second deflection channel 272 is used to guide the airflow to the output port 203b of the mixing channel. Finally, the airflow enters the storage chamber 101 through the output port 203b of the mixing channel, forming an airflow cycle.

[0203] In some embodiments, the first guide structure 260 is configured to change the airflow passing therethrough at a first angle, that is, the airflow output from the first channel 201 and the airflow output from the second channel 202 change direction at a first angle to achieve preliminary mixing.

[0204] In some embodiments, the second guide structure 270 is configured to change the airflow passing therethrough at a second angle, that is, the airflow output by the first guide structure 260 changes its flow direction at a second angle to achieve re-mixing.

[0205] In some embodiments, the first angle is smaller than the second angle. It is understandable that the first angle is used to receive airflows from different positions to achieve preliminary mixing; the second angle is used for remixing based on the preliminary mixing. If the first angle is equal to the second angle, that is, the angle between the airflow direction output by the first guide structure 260 and the airflow direction output by the second guide structure 270 remains unchanged, the airflow direction has not changed, and remixing cannot be satisfied; if the first angle is greater than the second angle, that is, the airflow output by the first guide structure 260 has a reduced angle after passing through the second guide structure 270, although it is conducive to the convergence of the airflow, it cannot significantly change the direction of the airflow, and thus a higher degree of airflow mixing cannot be performed.

[0206] Through the above-mentioned setting, a smaller angle makes it easier for the airflow to change direction, avoiding stagnation or turbulence of the airflow in the first guide structure 260 and maintaining good fluidity; through large-angle flow direction changes, the airflow is mixed multiple times on the basis of preliminary mixing, ensuring the uniformity and stability of the airflow.

[0207] In some embodiments, the value range of the first angle is less than 90°, and the value range of the second angle is less than or equal to 90°.

[0208] It can be understood that the value of the first angle can be 1°, 15°, 30°, 45°, 60°, 75°, 89°, etc., and the value of the second angle can be 1°, 15°, 30°, 45°, 60°, 75°, 89°, 90°, etc.

[0209] If the first angle is greater than 90°, the first channel 201 and the second channel 202 cannot converge, and the mixing effect of the first guide structure 260 cannot be achieved; when the second angle is greater than 90°, the flow direction of the second guide structure 270 is opposite to the flow direction of the airflow derived from the first guide structure 201, and the mixing effect of the second guide structure 270 cannot be achieved.

[0210] In some embodiments, the first angle has a value range of less than or equal to 45°, and the second angle has a value range of greater than or equal to 45° and less than or equal to 90°.

[0211] Through the above settings, the smaller angle makes it easier for the airflow to change direction, avoiding the stagnation or turbulence of the airflow in the guide structure and maintaining good fluidity. Through the large-angle flow direction change, the airflow is mixed multiple times on the basis of preliminary mixing, ensuring the uniformity and stability of the airflow.

[0212] Reference Fig.11In some embodiments, the first guide structure 260 is formed with a mixing guide channel 261, a first guide channel 262, and a second guide channel 263. The mixing guide channel 261 is connected to the upstream of the air mixing channel 203 to ensure that the airflow can be effectively mixed. The first guide channel 262 is connected to the downstream of the first channel 201 and the upstream of the mixing guide channel 261, and is used to guide the airflow of the first channel 201 into the mixing guide channel 261. The second guide channel 263 is connected to the downstream of the second channel 202 and the upstream of the mixing guide channel 261, and is used to guide the airflow of the second channel 202 into the mixing guide channel 261.

[0213] In some embodiments, the first guide structure 260 is configured so that the first guide channel 262 and the second guide channel 263 both flow unidirectionally toward the mixing guide channel 261, so that the first channel 201 and the second channel 202 both flow unidirectionally toward the air mixing channel 203. That is, the airflow in the first guide channel 262 will not enter the second guide channel 263, and the airflow in the second guide channel 263 will not enter the first guide channel 262.

[0214] Reference Fig.11 In some embodiments, the airflow velocity received by the mixing guide channel 261 is respectively smaller than the airflow velocity output by the first guide channel 262 and the airflow velocity output by the second guide channel 263. In this way, by forming guide channels with different airflow velocities, the airflow contracts downstream of the first guide channel 262 and the second guide channel 263. When the airflow is at this position of the channel, the airflow velocity increases and the pressure decreases, forming a Venturi effect, thereby forming a one-way flow. That is, the airflow in the first guide channel 262 will not enter the second guide channel 263, and the airflow in the second guide channel 263 will not enter the first guide channel 262.

[0215] Reference Fig.12 In some embodiments of the present application, the first guide structure 260 includes a first guide plate 264 , a second guide plate 265 and a third guide plate 266 , and the third guide plate 266 is located between the first guide plate 264 and the second guide plate 265 .

[0216] 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 mixing air 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.

[0217] 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 confluence and preliminary mixing effects of the first guide structure 260.

[0218] 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 .

[0219] The longer first guide plate 264 and the second guide plate 265 have a longer path, so that the airflow from the first channel 201 has more time and space for preliminary mixing before entering the mixing guide channel 261. The shorter length can reduce the resistance of the airflow, ensure that the airflow can smoothly enter the mixing guide channel 261, and improve the mixing efficiency.

[0220] It can be understood that in order to form the above-mentioned first guide channel 262 and the 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.

[0221] Specifically, the middle parts of the first guide plate 264 and the second guide plate 265 are both protruding in the direction toward the third guide plate 266, and the third guide plate 266 is protruding in the direction toward the second guide plate 265, and the protruding position is the downstream of the first guide channel 262 and the output port of the second guide channel 263, and is also the input port of the mixing guide channel 261. The protruding position of the third guide plate 266 is provided with an inlet 267, and the inlet 267 is used to realize a three-way connection. The three-way connection means that the mixing guide channel 261, the first guide channel 262 and the second guide channel 263 are connected to each other.

[0222] The arc-shaped design and the protrusion increase the airflow contact area, reduce resistance and vortex, and improve the mixing efficiency. Through the inlet 267, the two airflows can be mixed at the initial stage of converging, thereby improving the mixing efficiency.

[0223] It is understandable that, in order to ensure the connectivity between the multiple guide channels, 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 can be the same as the angle between the flow direction of the outlet of the second guide channel 262 and the flow direction of the outlet of the mixing guide channel 261.

[0224] The first angle mentioned above 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 refers to the angle between the flow direction of the outlet of the second guide channel 262 and the flow direction of the outlet of the mixing guide channel 261. The content of the first angle has been described in the previous text and will not be repeated here.

[0225] Reference Fig.13 In some embodiments, the airflow circulation assembly 200 further includes a second guide structure 270. The second guide structure 270 is located in the air mixing channel 203 and is used to change the flow direction of the airflow in the air mixing channel 203 multiple times.

[0226] By changing the airflow direction multiple times, the mixing effect of the airflow can be enhanced, the uniformity and stability of the airflow can be ensured, and the uniformity of the physical parameters of the output airflow can be improved.

[0227] In some embodiments, the second guide structure 270 is formed with a first direction-changing channel 271 , the first direction-changing channel 271 is close to the air mixing channel input port 203 a , and the flow direction of the first direction-changing channel 271 is different from the flow direction of the air mixing channel 203 .

[0228] 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.

[0229] Reference Fig.13 In some embodiments, 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. The multiple first deflection plates 273 are arranged at intervals in the air mixing channel 203, and a first deflection channel 271 is formed between two adjacent first deflection plates 273. The surface extension direction of the first deflection plate 273 intersects with the flow direction of the air mixing channel 203.

[0230] In this way, the airflow passing through the first changing channel 271 flows along the first direction A, and the flow direction of the mixing channel 203 is the second direction B. The first direction A is different from the second direction B, 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.

[0231] 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.

[0232] 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.

[0233] 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 mixing channel 203 is relatively large, thereby affecting the flow of air in the mixing channel 203.

[0234] Reference Fig.13 In some embodiments, the flow direction of the first direction-changing 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 airflow passing through the first direction-changing channel 271 and the airflow not passing through the first direction-changing channel 271 is larger, so that the mixing degree between the airflow passing through the first direction-changing channel 271 and the airflow not passing through the first direction-changing channel 271 is higher, which can improve the mixing effect of the air mixing channel 203 on the two airflows.

[0235] Reference Fig.14 In some embodiments, the second guide structure 270 is formed with a plurality of first direction-changing channels 271 , and the flow 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.

[0236] 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.

[0237] Reference Fig.13 In some embodiments, the second guide structure 270 is formed with a plurality of first direction-changing channels 271, and the flow directions of the plurality of first direction-changing channels 271 are the same. That is, the airflow directions in each first direction-changing channel 271 are the same, which can ensure that the second guide structure 270 can output airflow with a consistent flow path, thereby improving the uniformity and stability of the airflow.

[0238] 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.

[0239] 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 improve the uniformity of the storage environment.

[0240] In some embodiments, according to Re=ρvL0 / μ, Re is the Reynolds number required for the flow state of the airflow to be turbulent, ρ is the density of the airflow, v is the flow velocity of the airflow, L0 is the characteristic length required for the flow state of the airflow to become turbulent, and μ is the dynamic viscosity of the airflow. 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 airflow can be changed.

[0241] It is understandable that when the Reynolds number of the airflow is low (eg, less than 2000), the flow state of the airflow is usually 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.

[0242] For example, if the Reynolds number of the airflow reaches 2300, that is, Re=2300, the turbulence of the airflow can be effectively induced. In this example, assuming v=6m / s, μ=0.0000179Pa.s, ρ=1.29, then L0=5.3mm is obtained. That is, if the extension length of the first deflection plate 273 is 5.3mm, the turbulence of the airflow can be induced, thereby improving the mixing degree of the airflow.

[0243] It should be noted that the above data are only examples and can be adjusted according to actual conditions.

[0244] 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。

[0245] It can be understood that a reasonable ratio helps the airflow to change its state in the first changing channel 271 .

[0246] When the first deflection plate 273 is at the above ratio, the first deflection plate 273 can effectively change the flow state of the airflow, so that the flow state of the airflow is turbulent, thereby improving the mixing degree of the airflow. If L is less than the above ratio, the first deflection plate 273 is short, and the Reynolds number of the airflow cannot be increased, and turbulence cannot be caused; if L is greater than the above ratio, the first deflection plate 273 is long, and the flow resistance of the airflow increases, thereby affecting the flow of the airflow in the first deflection channel 271.

[0247] 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. On this basis, L can be half of L0. In this case, while achieving turbulence, it is easy to process the first deflection plate 273 with an integer length, thereby reducing the production accuracy and assembly accuracy of the first deflection plate 273.

[0248] In some embodiments, the shape of the first deflection plate 273 can be arbitrary. For example, the first deflection plate 273 can be a plate body or a column. For another example, the end surface of the first deflection plate 273 can be circular, rectangular, or rounded rectangular.

[0249] It is understandable that the aforementioned second angle refers to the angle between the flow direction of the first direction-changing channel 273 (ie, the first direction A) and the flow direction of the air mixing channel 203 (ie, the second direction B). The second angle has been described above and will not be repeated here.

[0250] Reference Fig.13 In some embodiments, when the surfaces of the plurality of first deflection plates 273 extend in the same direction, the flow directions of the plurality of first deflection channels 271 are the same. That is, the airflow directions in the first deflection channels 271 are the same, which can ensure that the second guide structure 270 can output airflow with a consistent flow path, thereby improving the uniformity and stability of the airflow.

[0251] Reference Fig.15 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。

[0252] It should be noted that the distance S1 may affect the size of the flow space of the airflow between two adjacent first deflection plates 273 .

[0253] It is understandable that a reasonable distance S1 helps the airflow to be fully mixed between adjacent first deflection plates 273 and improves the mixing efficiency. If S1 is less than the above ratio, the distance between two adjacent first deflection plates 273 is too small, which may cause the airflow to be unable to smoothly enter the first deflection channel 271, thereby affecting the flow of the airflow; if S1 is greater than the above ratio, the distance between two adjacent first deflection plates 273 is too large, and the flow rate of the airflow entering the first deflection channel 271 is low, thereby affecting the Reynolds number of the airflow, and thus failing to achieve a change in the flow state of the airflow.

[0254] Reference Fig.15 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.

[0255] 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 part of the flow state of the airflow will change; 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.

[0256] In some embodiments, the second guide structure 270 is formed with a second direction-changing channel 272, which is located downstream of the first direction-changing channel 271, and the flow direction of the second direction-changing channel 272 is the same as the flow direction of the air mixing channel 203, that is, the airflow passing through the second direction-changing channel 272 also flows along the second direction B. In this way, when the first direction-changing channel 271 outputs airflow, the second direction-changing channel 272 can change the airflow output by the first direction-changing channel 271 and mix it again; at the same time, the second direction-changing channel 272 can provide a guiding effect to improve the uniformity of the airflow flow, and ensure that the air mixing channel 203 can output an airflow with a high degree of mixing and high uniformity.

[0257] Reference Fig.14 In some embodiments, the second guide structure 200 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.

[0258] 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.

[0259] It is understandable that, according to the above content, when the Reynolds number of the airflow is low (for example, less than 2000), the flow state of the airflow is usually 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.

[0260] It can be understood that if the flow state of the airflow is laminar flow, 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.

[0261] Exemplarily, the extension length of the second deflection plate 274 is smaller than the extension direction of the first deflection plate 273 , which can effectively reduce the Reynolds number of the airflow.

[0262] In another exemplary embodiment, no structure is provided between the second deflection plate 274 and the first deflection plate 273, that is, the airflow enters the mixing channel 203 after passing through the first deflection channel 271. Since the maximum aperture of the mixing channel 203 through which the airflow can pass is much larger than the maximum aperture of the first deflection channel 271, the density of the airflow is rapidly reduced, which can also reduce the Reynolds number of the airflow.

[0263] Reference Fig.15 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 the adjacent first deflection plate 273 and the second deflection plate 274 is S2, and the relationship between L and S2 is: L <S2<L*6。

[0264] It should be noted that the distance S2 may affect the flow space between the first deflection plate 273 and the second deflection plate 274 .

[0265] It is understandable that a reasonable distance S2 helps the airflow to change its flow state between the first deflection plate 273 and the second deflection plate 274. If S2 is less than the above 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, and thus the output of laminar airflow cannot be achieved; if S2 is greater than the above ratio, the distance between the first deflection plate 273 and the second deflection plate 274 is too large, which may cause the airflow to be unable to smoothly enter the second deflection channel 272, thereby affecting the flow of the airflow.

[0266] 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.

[0267] 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 part of the flow state of the airflow will change; 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 the entire airflow is changed, there is also the possibility that the airflow cannot smoothly enter the second changing channel 272.

[0268] In some embodiments, the airflow circulation component 200 further includes a third guide structure 280 , which is connected to the air mixing channel output port 203 b and is used to receive the airflow output by the second guide structure 270 and change the flow direction so as to output it to the storage cavity 101 .

[0269] By means of the airflow circulation component 200 provided with the first guide structure 260, the second guide structure 270 and the third guide structure 280, the mixing degree of the airflow is increased, and the mixing efficiency and the mixing effect of the airflow are increased, so that the error between the airflow received by the storage cavity 101 and the target airflow is smaller, and higher-precision temperature and humidity adjustments can be achieved, which is conducive to forming storage conditions with constant physical parameters, thereby facilitating the storage of items.

[0270] Reference Fig.14 In some embodiments, the airflow circulation component 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.

[0271] By increasing the aperture of the outlet, 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.

[0272] Reference Fig.14 In some embodiments, the third guide structure 280 is formed with a first outlet channel 281, the first outlet channel 281 is connected to the air mixing channel outlet 203b, and the aperture of the outlet of the first outlet channel 281 is larger than the aperture of the air mixing channel outlet 203b. By increasing the aperture of the outlet, the flow rate of the airflow can be reduced, soft airflow can be achieved, and the airflow circulation in the storage cavity 101 can be ensured to be relatively stable and uniform.

[0273] In some embodiments, the third guide structure 280 is formed with a second outlet channel 282, the second outlet channel 282 is connected to the air mixing channel outlet 203b, and the aperture of the outlet of the second outlet channel 282 is larger than the aperture of the air mixing channel outlet 203b. By increasing the aperture of the outlet, the flow rate of the airflow can be reduced, soft airflow can be achieved, and the airflow circulation in the storage cavity 101 can be ensured to be more stable and uniform.

[0274] 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, it is ensured that the airflow can be distributed according to demand when leaving the air mixing channel 203, the flow rate of the airflow can be reduced, and different degrees of soft air discharge can be achieved.

[0275] 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 .

[0276] It is understandable that a larger outlet aperture can achieve a greater degree of soft air discharge, and a smaller outlet aperture can achieve a lesser degree of soft air discharge. Through the above configuration, 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 requirements, thereby achieving adaptive soft air discharge.

[0277] In some embodiments, the ratio between the aperture of the output port of the first outlet channel 281 and the aperture of the output port of the air mixing channel 203 is greater than or equal to 3.

[0278] 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.

[0279] Soft air outlet can reduce direct impact on stored items and protect the integrity of stored items.

[0280] In some embodiments, the ratio between the aperture of the output port of the second outlet channel 282 and the aperture of the air mixing channel output port 203 b is greater than or equal to 3.

[0281] 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.

[0282] Soft air outlet can reduce direct impact on stored items and protect the integrity of stored items.

[0283] 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 reach the standard of soft air output, and thus the soft air output cannot be effectively achieved.

[0284] Reference Fig.10 In some embodiments, the first outlet channel 281 and the second outlet channel 282 may be located at different positions in the storage cavity 101. For example, the first outlet channel 281 may be located above the second outlet channel 282; for example, the first outlet channel 281 may be located below the second outlet channel 282. The lower channel is closer to the items in the storage cavity 101 than the upper channel.

[0285] 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 .

[0286] Through the above arrangement, the first outlet channel 281 is close to the items in the storage cavity 101 and has a larger outlet 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.

[0287] Reference Fig.16 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 .

[0288] The air outlet 204 is located at the upper part of the decorative plate 210, and the air outlet 204 is connected to the air mixing channel output port 203b, and is connected to the upper part of the storage cavity 101. The air outlet 204 is used to discharge the mixed airflow to ensure that the mixed airflow can enter the storage cavity 101. The upper air outlet helps to evenly distribute the airflow in the storage cavity 101 and avoid local airflow stagnation.

[0289] The first air return port 205 is located at the lower part of the decorative plate 210, and is connected to the input port of the first channel 201 and the lower part of the storage cavity 101. The first air return port 205 is used to receive the airflow in the storage cavity 101, ensuring that the airflow in the storage cavity 101 can be effectively recycled into the first channel 201.

[0290] The second air return port 206 is located at the lower part of the decorative plate 210, and the second air return port 206 is connected to the input port of the second channel 202 and is connected to the lower part of the storage cavity 101. The second air return port 206 is used to receive the airflow in the storage cavity 101, ensuring that the airflow in the storage cavity 101 can be effectively recovered and enter the second channel.

[0291] The first return air port 205 and the second return air port 206 are respectively connected to different positions of the lower part of the storage cavity 101. By setting the return air ports at multiple positions, it is ensured that the airflow enters from different positions, thereby ensuring the uniform distribution of the airflow in the storage cavity 101 to avoid local airflow obstruction.

[0292] Reference Fig.10 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 .

[0293] Reference Fig.17 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.

[0294] 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.

[0295] Reference Fig.17 In some embodiments, the airflow circulation assembly 200 includes the aforementioned decorative plate 210, the front cover 220, the rear cover 230 and the rear plate 240, and 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 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 plate 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.

[0296] The first air return port 205 is connected to the middle position of the lower part of the storage chamber 101. The first air return port 205 can be connected to the auxiliary channel 209.

[0297] First, part of the airflow a1 in the storage cavity 101 enters the auxiliary channel 209 through the first return air port 205. After filling the return air cavity 231 between the front cover 220 and the rear cover 230, the airflow a1 enters the first channel 201.

[0298] Reference Fig.18 The refrigeration assembly 270 includes an evaporator 310, which is close to the input port of the first channel 201. The evaporator 310 cools and dehumidifies the airflow. A second fan 252 is provided on the output side of the evaporator 310. The second fan 252 is a centrifugal fan that can absorb the airflow output by the evaporator 271 and guide the airflow to the air mixing channel 203.

[0299] 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 the humidified air flow a3 through the second air return port 206 and enter the second channel 202B.

[0300] At the same time, another part of the airflow a2 in the storage chamber 101 and the humidified airflow a3 output by the humidification component 500 pass through the second return air port 206 and enter the two first channels 201 respectively. The two first channels 201 are respectively provided with a first fan 251. The first fan 251 is an axial fan that can guide the airflow to the air mixing channel 203.

[0301] The two heating components 400 are located near the outlets of the two second channels 202B to increase the air temperature of the air flowing through the two second channels 202B. Thus, the first channel 201 outputs a cooling and dehumidifying air flow a4, and the second channel 202B outputs a heating and humidifying air flow a5.

[0302] Then, the two airflows enter the first guide channel 262 and the second guide channel 263 formed by the first guide structure 260 , respectively. The two airflows change their flow rates and are preliminarily mixed in the mixing guide channel 261 .

[0303] Then, the second guide structure 270 receives the airflow output by the first guide structure 270 and passes through the first deflection channel 271. The adjacent first deflection plate 273 forms the first deflection channel 271. The first deflection plate 273 can change the Reynolds number of the airflow to change the airflow from a laminar state to a turbulent state and enhance the mixing degree of the two airflows. The airflow output by the first deflection channel 271 briefly enters the air mixing channel 203 and then enters the second deflection channel 272 of the second guide structure 270. The adjacent second deflection plate 274 forms the second deflection channel 272. The second deflection plate 274 can change the airflow from a turbulent state to a laminar state.

[0304] 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 export channel 281 and a second export channel 282. The calibers of the output ports of the first export channel 281 and the second export channel 282 are both increased, so as to achieve a soft outlet of the airflow. The output port of the first export channel 281 is located above the output port of the second export channel 282. The output port of the first export 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 export 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.

[0305] 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 .

[0306] The fluctuation of the physical parameter changes between the airflow a7 and a8 received by the storage cavity 101 and the airflow a1 and a2 released is small. In this way, when the airflow flow time remains unchanged, the physical parameters of the airflow change multiple times. Compared with 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, which is conducive to forming a storage condition with constant physical parameters, and then the airflow in the storage cavity 101 can be located within a preset range, which is conducive to the storage of items.

The fence can provide a closed structure to prevent items from falling.

[0311] In some embodiments, there may be multiple dividing ribs, and the multiple dividing ribs may be arranged in parallel or in an intersecting manner to separate the space of the fence.

[0313] Through the above settings, users can classify and store items according to indicators such as type and size, which improves space utilization and reduces mixing and interference between items.

[0314] In some embodiments, the carrier includes a main body and a movable plate, wherein the movable plate is rotatably connected to the main body and can be rotated downward or upward.

[0315] The carrier is used to support and fix other components, and the movable plate can move within a certain range. The main body provides a stable support structure to ensure the overall strength and stability of the carrier. The design of the movable plate increases flexibility, and the position and angle of the plate can be adjusted as needed, which is convenient for the storage and fixation of items.

[0316] Through the above settings, the support frame provides users with a flexible operation method, and the position and angle of the movable board can be adjusted according to actual needs.

[0319] In some embodiments, a light bar may be provided on the side of the rib plate 840 facing away from the supporting plate 830 to illuminate the storage cavity 101 .

[0320] In some embodiments, the light bar may also be disposed on the supporting plate 830 .

[0321] In some embodiments, if the stored items are cigars, the carrier 800 may be a cedar wood carrier 800, which is conducive to the aging of the cigars and improves the taste of the cigars.
