Description

Technical Field

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

[0002] With the development of technology and the improvement of living standards, people have higher requirements for the storage period of items, especially for items with relatively harsh environmental conditions, such as fresh food, cigars, and alcoholic beverages.

[0003] In related technologies, in order to maintain a long storage time and ensure relatively constant storage conditions, a storage cavity has been invented. By setting heaters, heat exchangers, etc. in the storage cavity and regulating the operation of electrical components such as heaters and heat exchangers, the storage temperature of the storage cavity is adjusted. Exemplarily, a warm air channel is provided in a storage cabinet to increase the temperature of the storage cavity. However, constant temperature can no longer meet the storage needs of people for high - requirement items, and more constant conditions such as humidity need to be introduced.

[0004] However, in a storage cabinet with multi - type channel transportation, the air flow passes through different types of machines in sequence through air guide holes to adjust the temperature and humidity. The time required to adjust the air flow is relatively long, and it cannot meet the customer's demand for quickly adjusting the temperature and humidity. Summary of the Utility Model

[0005] Some embodiments of the present application provide a storage box. By providing two independent channels and connecting different return air outlets, the air flow can be divided into two strands and enter the two channels respectively, increasing the air flow velocity, so as to reduce the time required to adjust the temperature and humidity of the air flow, and further meet the customer's demand for quickly adjusting the temperature and humidity of the air flow.

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

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

[0008] An air flow circulation component, including:

[0009] A first channel, the input port of the first channel being connected to the storage cavity;

[0010] A second channel, the input port of the second channel being connected to the storage cavity;

[0011] A mixing air channel, having:

[0012] A mixing air channel input port, connected to the output ports of the first channel and the second channel;

[0013] A mixing air channel output port, connected to the storage cavity;

[0014] A blower, located in at least one of the air mixing channel, the first channel, and the second channel, is used to drive the airflow to flow;

[0015] A decorative panel, having:

[0016] An air outlet, located at the upper part of the decorative panel, is connected to the air outlet of the air mixing channel and is also connected to the upper part of the storage cavity;

[0017] A first air return opening, located at the lower part of the decorative panel, is connected to the input port of the first channel and is also connected to the lower part of the storage cavity;

[0018] A second air return opening, located at the lower part of the decorative panel, is connected to the input port of the second channel and is also connected to the lower part of the storage cavity;

[0019] The first air return opening and the second air return opening are respectively connected to different positions at the lower part of the storage cavity.

[0020] The storage box provided by some embodiments of the present application has a storage cavity and an air flow circulation component connected to the storage cavity. The air flow circulation component receives the air flow in the storage cavity through the first channel and the second channel respectively, and is provided with a first air return opening and a second air return opening corresponding to different channels through the decorative panel. An air outlet for air outlet is also provided on the decorative panel.

[0021] In this way, part of the air flow can enter the first channel through the first air return opening, and another part of the air flow can enter the second channel through the second air return opening. The air flow can be divided into two parts and flow simultaneously, and the overall flow speed of the air flow increases, which can meet the customer's demand for quick adjustment.

[0022] In addition, by setting the air return opening and the air outlet, the air return opening introduces the air flow from the storage cavity to the air flow circulation component, and the air outlet leads the air flow from the air flow circulation component to the storage cavity. The entry and output of the air flow do not conflict, avoiding air flow short - circuit, which is beneficial to increasing the flow speed of the air flow, and further increasing the speed of changing the temperature and humidity of the air flow, meeting the customer's demand for quick adjustment.

[0023] In some embodiments of the present application, the number of the first air return openings is multiple;

[0024] The second air return opening is arranged near the mid - line position of the storage cavity, and multiple first air return openings are all arranged outside the second air return opening.

[0025] With such an arrangement, multiple first air return openings help ensure that the air flow in the storage cavity can be evenly recovered, avoiding unsmooth local air flow. The second air return opening is arranged near the midline position of the storage cavity, which helps to concentrate the return air and improve the efficiency of air flow recovery. The first air return opening is arranged outside the second air return opening, which helps to recover the peripheral air flow. The design of the air return openings at the outer side and the midline position helps to achieve stratified recovery of the air flow, improve the circulation efficiency of the air flow, and ensure the uniformity and stability of the air flow circulation in the storage cavity.

[0026] In some embodiments of the present application, the number of the second air return openings is multiple;

[0027] The first air return opening is arranged near the midline position of the storage cavity, and multiple second air return openings are all arranged outside the first air return opening.

[0028] With such an arrangement, multiple second air return openings help ensure that the air flow in the storage cavity can be evenly recovered, avoiding unsmooth local air flow. The first air return opening is arranged near the midline position of the storage cavity, which helps to concentrate the return air and improve the efficiency of air flow recovery. The second air return opening is arranged outside the first air return opening, which helps to recover the peripheral air flow. The design of the air return openings at the outer side and the midline position helps to achieve stratified recovery of the air flow, improve the circulation efficiency of the air flow, and ensure the uniformity and stability of the air flow circulation in the storage cavity.

[0029] In some embodiments of the present application, the air flow circulation component further includes:

[0030] A front cover, located on the side of the decorative plate away from the storage cavity, and at least part of the second channel is formed between the front cover and the decorative plate;

[0031] A rear cover, located on the side of the front cover away from the storage cavity, and the mixing air channel is formed between the rear cover and the front cover;

[0032] A back plate, located on the side of the rear cover away from the storage cavity, and the first channel is formed between the back plate and the rear cover.

[0033] With such an arrangement, the decorative plate, the front cover, the rear cover and the back plate can be sequentially stacked and connected to form the aforementioned first channel, second channel and mixing air channel, thereby forming the air flow circulation between the storage cavity and the air flow circulation component.

[0034] In some embodiments of the present application, the air flow circulation component includes a third guiding structure, and the third guiding structure includes:

[0035] A first guiding section, which forms a first guiding channel, the first guiding channel is communicated with the output port of the mixing air channel, and the aperture of the output port of the first guiding channel is larger than the aperture of the output port of the mixing air channel;

[0036] A second derivation section forms a second derivation channel that communicates with the outlet of the air mixing channel, and the aperture of the outlet of the second derivation channel is larger than that of the outlet of the air mixing channel; wherein,

[0037] The aperture of the outlet of the first derivation channel is different from that of the outlet of the second derivation channel.

[0038] With such a setting, the storage box can adjust the positions of the first derivation channel and the second derivation channel according to the stored items to match items with different requirements, so as to perform adaptive gentle air outlet.

[0039] In some embodiments of the present application, the decorative panel has:

[0040] A first air outlet that communicates with the first derivation channel;

[0041] A second air outlet that communicates with the second derivation channel;

[0042] The first air outlet and the second air outlet are respectively located at different positions on the upper part of the decorative panel, and the apertures of the outlets of the first air outlet and the second air outlet are the same.

[0043] With such a setting, the same aperture can ensure that the flow resistance of the air flow at the two air outlets is the same, avoid the flow velocity difference of the air flow at the air outlets, and further ensure that the flow rate of the air flow at the two air outlets is the same, so as to improve the uniformity and stability of air flow regulation.

[0044] In some embodiments of the present application, the aperture of the outlet of the first derivation channel is larger than that of the outlet of the second derivation channel, and the first derivation channel is located below the second derivation channel;

[0045] The second air outlet is located on the upper part of the decorative panel, and the first air outlet is located below the second air outlet.

[0046] With such a setting, the first derivation channel is close to the items in the storage cavity and has a larger ventilation area, which can ensure that the flow velocity of the air flow will be significantly reduced when output, so as to achieve gentle air outlet and ensure that the air flow circulation in the storage cavity is relatively stable and uniform.

[0047] In some embodiments of the present application, the ratio between the aperture of the outlet of the first derivation channel and the aperture of the outlet of the air mixing channel is greater than or equal to 3;

[0048] And / or,

[0049] The ratio between the aperture of the outlet of the second derivation channel and the aperture of the outlet of the air mixing channel is greater than or equal to 3.

[0050] With such a setting, when the aperture of the output port of the first export channel and the aperture of the output port of the second export channel are both 3 times or more of the aperture of the output port of the mixing air channel, the air flow velocity will be significantly reduced when the air flows out, so as to achieve gentle air outlet and ensure relatively stable and uniform air flow circulation in the storage cavity. Gentle air outlet can reduce the direct impact on the stored items and protect the integrity of the stored items.

[0051] In some embodiments of the present application, the ratio range between the aperture of the output port of the second export channel and the aperture of the output port of the first export channel is greater than 1 and less than or equal to 3.

[0052] With such a setting, it can be ensured that the flow path of the air flow between the export channels is relatively long, the contact area between the air flows is increased, and the mixing efficiency is improved; at the same time, it is ensured that the air flow realizes gentle air outlet through the first export channel, and the air flow circulation in the storage cavity is relatively stable and uniform.

[0053] In some embodiments of the present application, the ratio between the aperture of the output port of the second export channel and the aperture of the output port of the first export channel is 7:3.

[0054] With such a setting, it can be ensured that the flow path of the air flow between the export channels is relatively long, the contact area between the air flows is increased, and the mixing efficiency is improved; at the same time, it is ensured that the air flow realizes gentle air outlet through the first export channel, and the air flow circulation in the storage cavity is relatively stable and uniform.

Obviously, the described exemplary embodiments are only a part rather than all of the embodiments of this application.

Unless otherwise specified, these terms should be understood in their ordinary and common meanings.

[0083] In addition, the terms "include" and "have" and any of their variations are intended to cover but not exclusively include. For example, a product or device including a series of components does not necessarily have to be limited to those clearly listed components, but may include other components not clearly listed or inherent to these products or devices.

[0084] In the description of this application, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for facilitating the description of this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to this application.

[0085] 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 quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0086] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0087] Next, some embodiments of this application will be described clearly and completely with reference to the accompanying drawings in some embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, rather than all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0088] In the related art, as disclosed in a constant temperature and humidity cigar cabinet and its control method in Chinese Patent CN108273572A, air sequentially passes through a first area where the air flow can be heated and a second area where the air flow can be cooled. A humidifying device can also be communicated in the first area, so as to realize the adjustment of temperature and humidity. The adjusted air is led out through the air guiding holes on the air guiding plate. The unadjusted air is blown obliquely by a circulation fan towards the air flowing in through the air guiding holes for adjustment. However, in the above solution, both the air flow input and output pass through the air guiding holes, which easily causes conflicts and hinders the air flow. In addition, the air flow needs to pass through the first area and the second area in sequence before being led out, and the time required to adjust the temperature and humidity of the air flow is relatively long.

[0089] In view of this, some embodiments of this application provide a storage box, which has a storage cavity and an air flow circulation component communicated with the storage cavity. The air flow circulation component receives the air flow in the storage cavity through a first channel and a second channel respectively, and sets a first air return port and a second air return port corresponding to different channels through a decorative plate. An air outlet for air outlet is also provided on the decorative plate.

[0090] In this way, part of the air flow can enter the first channel through the first air return port, and another part of the air flow can enter the second channel through the second air return port. The air flow can be divided into two parts and flow simultaneously, and the overall flow speed of the air flow increases, which can meet the needs of customers for quick adjustment.

[0091] In addition, by setting the air return opening and the air outlet, the air return opening introduces the air flow from the storage cavity into the air flow circulation component, and the air outlet leads the air flow from the air flow circulation component to the storage cavity. The entry and output of the air flow will not conflict, avoiding air flow short - circuit, which is beneficial to increasing the speed of air flow, and then increasing the speed of changing the temperature and humidity of the air flow, meeting the needs of customers for rapid adjustment.

[0092] In this application, it should be understood that the meanings of the related terms are as follows:

[0093] Ventilation volume: The volume of air passing through a certain cross - section per unit time.

[0094] Venturi effect: According to the fluid continuity equation and Bernoulli's equation, when a fluid flows through a converging duct, due to the increase in the fluid velocity, its kinetic energy increases, while the pressure energy decreases accordingly. This means that in the narrow part of the converging duct, the fluid velocity is the highest and the pressure is the lowest.

[0095] Preset range: Adapt to the storage conditions of the stored items.

[0096] Laminar flow: It refers to the flow of fluid particles along parallel paths or layers without mixing with each other.

[0097] Turbulent flow: It refers to the flow of fluid particles in an irregular and chaotic manner, with strong mixing and vortices occurring inside the fluid.

[0098] Refer to Figure 1 , in some embodiments, the storage box 10 includes a box body 100. The box body 100 is the main structure of the storage box 10, and a space for storing items, that is, a storage cavity 101, is formed inside. In this way, the box body 100 can provide a closed storage space, facilitating the control of the internal environmental conditions.

[0099] In some embodiments, the storage box 10 includes an air flow circulation component 200, and the air flow circulation component 200 is used to adjust the air flow in the storage cavity 101, including but not limited to adjusting the flow rate, ventilation volume, temperature, humidity, oxygen content, etc. of the air flow.

[0100] Refer to Figure 2 , in some embodiments, the storage box 10 includes an air flow circulation component 200, and the air flow circulation component 200 is used to adjust the air flow in the storage cavity 101, including but not limited to adjusting the flow rate, ventilation volume, temperature, humidity, oxygen content, etc. of the air flow.

[0101] In some embodiments, the air flow circulation component 200 is located outside the storage box 10, that is, the air flow circulation component 200 does not occupy the storage cavity 101, so as to facilitate the storage of more items.

[0102] Refer to Figure 1, in some embodiments, the air flow circulation component 200 is located inside the storage box 10, that is, the air flow circulation component 200 is located inside the storage box 10, which facilitates the air flow circulation component 200 to receive the air flow output from the storage cavity 101 and also facilitates the air flow circulation component 200 to output the air flow from the storage cavity 101.

[0103] In some embodiments, the air flow circulation component 200 has a first channel 201 for conveying air flow. The first channel 201 has an input port and an output port. The side where the air flow enters the first channel 201 is the input port, and the side where the air flow exits the first channel 201 is the output port. The input port of the first channel 201 is communicated with the storage cavity 101, that is, the first channel 201 is connected to the storage cavity 101, and the first channel 201 can receive the air flow in the storage cavity 101.

[0104] In some embodiments, the air flow circulation component 200 has a second channel 202 for conveying air flow. The second channel 202 also has an input port and an output port, which will not be elaborated here. The input port of the second channel 202 is communicated with the storage cavity 101, that is, the second channel 202 is connected to the storage cavity 101, and the second channel 202 can receive the air flow in the storage cavity 101.

[0105] In some embodiments, the air flow circulation component 200 has a mixing air channel 203 with a mixing air channel input port 203a and a mixing air channel output port 203b. The mixing air channel input port 203a is simultaneously communicated with the output port of the first channel 201 and the output port of the second channel 202, and the mixing air channel output port 203b is communicated with the storage cavity 101. The mixing air channel 203 is used to receive the air flows input from the first channel 201 and the second channel 202 and output the mixed air flow to the storage cavity 101 after mixing.

[0106] It can be understood that the first channel 201 and the second channel 202 respectively form an air flow. In this way, the two air flows enter the mixing air channel 203 and are mixed in the mixing air channel 203. Therefore, the physical parameters of the air flow output from the mixing air channel 203 are between the physical parameters of the air flow in the first channel 201 and the physical parameters of the air flow in the second channel 202.

[0107] That is to say, the physical parameters of the air flow output by the air flow circulation component 200 are between the physical parameters of the air flow received by the air flow circulation component 200 and the physical parameters of the air flow inside the air flow circulation component 200.

[0108] In some embodiments, the air flow circulation component 200 includes a fan 250 for driving the air flow to flow.

[0109] It can be understood that the fan 250 can be an axial fan, and the air flow is axially flowed along the axial direction of the fan blades under the action of the axial fan. The fan 250 can also be a centrifugal fan, and the air flow is radially flowed along the radial direction of the fan blades under the action of the centrifugal fan. The fan 250 can also be a mixed-flow fan, and under the action of the mixed-flow fan, part of the air flow is axially flowed along the axial direction of the fan blades, and the other part is radially flowed along the radial direction of the fan blades.

[0110] In some embodiments, the fan 250 is located in at least one of the first channel 201, the second channel 202, and the air mixing channel 203, so that the air flow output from the storage cavity 101 can enter the air flow circulation assembly 200, and the air flow output from the air flow circulation assembly 200 can flow back to the storage cavity 101, forming an air flow circulation of storage cavity 101 - air flow circulation assembly 200 - storage cavity 101.

[0111] Refer to Figure 3 , in some embodiments, the decorative panel 210 has an air outlet 204, a first air return opening 205, and a second air return opening 206.

[0112] The air outlet 204 is located at the upper part of the decorative panel 210. The air outlet 204 is communicated with the output port 203b of the air mixing channel and is also communicated with the upper part of the storage cavity 101. The air outlet 204 is used to discharge the mixed air flow to ensure that the mixed air flow can enter the storage cavity 101. The upper air outlet helps the uniform distribution of the air flow in the storage cavity 101 and avoids the non-uniformity of the local air flow.

[0113] The first air return opening 205 is located at the lower part of the decorative panel 210. The first air return opening 205 is communicated with the input port of the first channel 201 and is also communicated with the lower part of the storage cavity 101. The first air return opening 205 is used to receive the air flow in the storage cavity 101 to ensure that the air flow in the storage cavity 101 can be effectively recycled into the first channel 201.

[0114] The second air return opening 206 is located at the lower part of the decorative panel 210. The second air return opening 206 is communicated with the input port of the second channel 202 and is also communicated with the lower part of the storage cavity 101. The second air return opening 206 is used to receive the air flow in the storage cavity 101 to ensure that the air flow in the storage cavity 101 can be effectively recycled into the second channel.

[0115] The first air return opening 205 and the second air return opening 206 are respectively communicated with different positions at the lower part of the storage cavity 101. By providing air return openings at multiple positions, it is ensured that the air flow enters from different positions, thereby ensuring the uniform distribution of the air flow in the storage cavity 101 to avoid the non-uniformity of the local air flow.

[0116] Refer to Figure 4, in some embodiments, the number of the first air return openings 205 is multiple, the second air return opening 206 is disposed near the midline position of the storage cavity 101, and the multiple first air return openings 205 are all disposed outside the second air return opening 206.

[0117] The multiple first air return openings 205 help to ensure that the air flow in the storage cavity 101 can be evenly recovered, avoiding non-uniform air flow in some areas. The arrangement of the second air return opening 206 near the midline position of the storage cavity 101 helps to concentrate the return air and improve the efficiency of air flow recovery. The first air return openings 205 are disposed outside the second air return opening 206, which helps to recover the peripheral air flow. The design of the air return openings at the outer side and the midline position helps to achieve stratified air flow recovery, improve the air flow circulation efficiency, and ensure the uniformity and stability of the air flow circulation in the storage cavity 101.

[0118] Refer to Figure 5 , in some embodiments, the number of the second air return openings 206 is multiple, the first air return opening 205 is disposed near the midline position of the storage cavity 101, and the multiple second air return openings 206 are all disposed outside the first air return opening 205.

[0119] The multiple second air return openings 206 help to ensure that the air flow in the storage cavity 101 can be evenly recovered, avoiding non-uniform air flow in some areas. The arrangement of the first air return opening 205 near the midline position of the storage cavity 101 helps to concentrate the return air and improve the efficiency of air flow recovery. The second air return openings 206 are disposed outside the first air return opening 205, which helps to recover the peripheral air flow. The design of the air return openings at the outer side and the midline position helps to achieve stratified air flow recovery, improve the air flow circulation efficiency, and ensure the uniformity and stability of the air flow circulation in the storage cavity 101.

[0120] Refer to Figure 6 , in some embodiments, the air flow circulation assembly 200 includes an adjustment assembly 20 for changing the physical parameters of the flowing air. The physical parameters include but are not limited to the aforementioned temperature, humidity, oxygen content, etc.

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

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

[0123] Refer to Figure 6, 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 lower the temperature of the air flow passing through the first channel 201 so that the mixing air channel 203 outputs an air flow with a lower temperature. The type of the refrigeration component 300 can be selected according to the actual situation.

[0124] 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 flowing air flow, and thus while reducing the humidity of the air flow, absorb heat to complete refrigeration.

[0125] Refer to Figure 6 , in some embodiments, when the physical parameter includes temperature, the adjustment component 20 includes a heating component 400. The heating component 400 is located in the second channel 202 and is used to increase the temperature of the air flow passing through the second channel 202 so that the mixing air channel 203 outputs an air flow with a higher temperature. The type of the heating component 400 can be selected according to the actual situation.

[0126] Refer to Figure 6 , in some embodiments, when the physical parameter includes humidity, the adjustment component 20 includes a humidifying component 500. The humidifying component 500 can increase the humidity of the air flow so that the mixing air channel 203 outputs an air flow with a high humidity. The type of the humidifying component 500 can be selected according to the actual situation.

[0127] Refer to Figure 6 , in some embodiments, the humidifying component 500 is located in the second channel 202 and is used to increase the humidity of the air flow passing through the second channel 202. That is, the humidifying component 500 is directly installed in the second channel 202. When the air flow passes through the second channel 202, the humidifying component 500 will humidify the air flow, so that the humidity of the air flow passing through the second channel 202 increases.

[0128] Through the above settings, the humidifying component 500 can effectively humidify the air flow to ensure that when the air flow passes through the second channel 202, the humidity can reach the expected level at a relatively fast speed. In addition, the humidifying component 500 and the second channel 202 form an integral body, and the structure is relatively compact; in addition, the humidifying component 500 can more accurately control the humidity of the air flow, reduce humidity fluctuations, and improve the humidity stability of the storage environment.

[0129] Refer to Figure 6, in some embodiments, if the second channel 202 may include multiple connected parts. Exemplarily, the second channel 202 may include a second channel 202A and a second channel 202B, the second channel 202A and the second channel 202B are connected, and the second channel 202A is located upstream of the second channel 202B.

[0130] It should be noted that the connection between the second channel 202A and the second channel 202B may include various ways. Exemplarily, the second channel 202A and the second channel 202B are directly connected in sequence end to end. Another exemplary way is that both the second channel 202A and the second channel 202B are connected to the storage cavity 101, and the air flow in the storage cavity 101 and the air flow in the second channel 202A can enter the second channel 202B. Another exemplary way is that the second channel 202A is connected to the second channel 202B through a pipeline, etc.

[0131] It should be noted that the first channel 201 may also include multiple parts. The content can refer to the second channel 202 including multiple connected parts, which will not be elaborated here.

[0132] In some embodiments, both the second channel 202A and the second channel 202B are connected to the storage cavity 101, and the air flow in the storage cavity 101 and the air flow in the second channel 202A can enter the second channel 202B. The humidifying assembly 500 is located in the second channel 202A and is used to provide humidified air flow to the second channel 202B. The air flow in the storage cavity 101 and the air flow in the second channel 202 can both flow to the second channel 202A.

[0133] Through the above settings, the humidifying assembly 500 and the second channel 202 are located at different positions. When repairing or replacing the humidifying assembly 500, it is not necessary to disassemble the second channel 202, which can improve the convenience of maintenance.

[0134] In some embodiments, the adjustment assembly 20 includes a refrigeration assembly 300, a humidifying assembly 500, and a heating assembly 400. The refrigeration assembly 300 can reduce the temperature of the air flow flowing through the first channel 201, the heating assembly 400 can increase the temperature of the air flow output by the second channel 202, and the humidifying assembly 500 can increase the humidity of the air flow output by the second channel 202. In this way, the storage box 10 not only has two temperature adjustment methods with relatively high temperature adjustment accuracy, but also can adjust the humidity. At this time, the storage box 10 can be used for items such as cigars that have relatively high storage requirements for both temperature and humidity.

[0135] Refer to Figure 6 , in some embodiments, the air flow circulation assembly 200 further includes 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.

[0136] The front cover 220 is located on the side of the decorative panel 210 facing away from the storage cavity 101. At least a part of the second channel 202 is formed between the front cover 220 and the decorative panel 210. That is, a part of the second channel 202 can be formed between the front cover 220 and the decorative panel 210, or the entire second channel 202 can be formed. The rear cover 230 is located on the side of the front cover 220 facing away from the storage cavity 101. A mixed air 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 facing away from the storage cavity 101. A first channel 201 is formed between the back plate 240 and the rear cover 230.

[0137] It can be understood that the decorative panel 210, the front cover 220, the rear cover 230, and the back plate 240 can be sequentially stacked and connected to form the aforementioned first channel 201, second channel 202, and mixed air channel 203.

[0138] 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 at the middle position of the rear cover 230. Two second channels 202 are formed between the front cover 220 and the decorative panel 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 both located at the lower part of the storage cavity 101. The mixed air channel 203 is located at the upper part of the storage cavity 101.

[0139] It can be understood that in the above structure, the air flow in the storage cavity 101 enters the first channel 201 and the two second channels 202 respectively, then the air flow in the first channel 201 and the two second channels 202 enters the mixed air channel 203, and finally, the air flow in the mixed air channel 203 is output and enters the storage cavity 101, forming an air flow cycle between the storage cavity 101 and the air flow circulation assembly 200.

[0140] Refer to Figure 6 , in some embodiments, as described above, if the second channel 202 includes a second channel 202A and a 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 at the middle position of the rear cover 230.

[0141] In some embodiments, the decorative panel 210 and the front cover 220 can jointly form the second channel 202B. At this time, the position of the second channel 202A can be selected according to the actual situation. Exemplarily, the second channel 202B is located at the lower part of the storage cavity 101. Another exemplary is that the second channel 202B is located outside the storage cavity 101. Yet another exemplary is that the second channel 202B is located at the rear side of the storage cavity 101.

[0142] 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 on both 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.

[0143] It can be understood that in the above structure, the air flow in the storage cavity 101 enters the first channel 201 and the two second channels 202B respectively, then the air flow in the first channel 201 and the two second channels 202B enters the air mixing channel 203, and finally, the air flow in the air mixing channel 203 is output into the storage cavity 101, forming an air flow circulation between the storage cavity 101 and the air flow circulation assembly 200.

[0144] Refer to Figure 7 , in some embodiments, the air flow circulation assembly 200 further includes a first guiding structure 260. The first guiding structure 260 is formed with a mixing guiding channel 261, a first guiding channel 262 and a second guiding channel 263. The mixing guiding channel 261 communicates with the upstream of the air mixing channel 203 to ensure effective mixing of the air flow. The first guiding channel 262 communicates with the downstream of the first channel 201 and the upstream of the mixing guiding channel 261, and is used to guide the air flow in the first channel 201 into the mixing guiding channel 261. The second guiding channel 263 communicates with the downstream of the second channel 202 and the upstream of the mixing guiding channel 261, and is used to guide the air flow in the second channel 202 into the mixing guiding channel 261.

[0145] In some embodiments, the first guiding structure 260 is configured such that the air flow in both the first guiding channel 262 and the second guiding channel 263 flows unidirectionally towards the mixing guiding channel 261, so that the air flow in both the first channel 201 and the second channel 202 flows unidirectionally towards the air mixing channel 203. That is, the air flow in the first guiding channel 262 does not enter the second guiding channel 263, and the air flow in the second guiding channel 263 does not enter the first guiding channel 262.

[0146] Refer to Figure 8 , in some embodiments, the air flow velocity received by the mixing guiding channel 261 is respectively less than the air flow velocity output by the first guiding channel 262 and the air flow velocity output by the second guiding channel 263. In this way, by forming guiding channels with different air flow velocities, the air flow contracts downstream of the first guiding channel 262 and the second guiding channel 263. When the air flow is at this position in the channel, the air flow velocity increases and the pressure decreases, forming a Venturi effect, thereby forming a unidirectional flow. That is, the air flow in the first guiding channel 262 does not enter the second guiding channel 263, and the air flow in the second guiding channel 263 does not enter the first guiding channel 262.

[0147] Refer to Figure 7, in some embodiments of the present application, the first guiding structure 260 includes a first guiding plate 264, a second guiding plate 265, and a third guiding plate 266, and the third guiding plate 266 is located between the first guiding plate 264 and the second guiding plate 265.

[0148] Among them, the second guiding plate 265 and the first guiding plate 264 jointly form a mixed guiding channel 261, and the mixed guiding channel 261 communicates with the upstream of the air mixing channel 203; a first guiding channel 262 is formed between the third guiding plate 266 and the first guiding plate 264, and the first guiding channel 262 communicates with the downstream of the first channel 201 and the upstream of the mixed guiding channel 261; a second guiding channel 263 is formed between the third guiding plate 266 and the second guiding plate 265, and the second guiding channel 263 communicates with the downstream of the second channel 202 and the upstream of the mixed guiding channel 261.

[0149] In this way, the first guiding structure 260 can form a first guiding channel 262 communicating with the first channel 201, a second guiding channel 263 communicating with the second channel 202, and a mixed guiding channel 261 communicating with the air mixing channel inlet 203a, thereby realizing the confluence function and the preliminary mixing function of the first guiding structure 260.

[0150] In some embodiments, along the flow direction of the air mixing channel 203, the lengths of the first guiding plate 264 and the second guiding plate 265 are both greater than the length of the third guiding plate 266.

[0151] The longer first guiding plate 264 and second guiding plate 265 have a longer path, so that the air flow from the first channel 201 has more time and space for preliminary mixing before entering the mixed guiding channel 261. The shorter length can reduce the resistance of the air flow, ensure that the air flow can smoothly enter the mixed guiding channel 261, and improve the mixing efficiency.

[0152] It can be understood that in order to form the above-mentioned first guiding channel 262 and second guiding channel 263, the first guiding plate 264, the second guiding plate 265, and the third guiding plate 266 can all be arc-shaped plates.

[0153] Specifically, the middle parts of the first guiding plate 264 and the second guiding plate 265 both protrude in the direction towards the third guiding plate 266, and the third guiding plate 266 protrudes in the direction towards the second guiding plate 265. The protruding positions are the downstream of the first guiding channel 262 and the outlet of the second guiding channel 263, and at the same time are the inlet of the mixed guiding channel 261. An inlet 267 is provided at the protruding position of the third guiding plate 266, and the inlet 267 is used to realize a three-way connection. The three-way connection means that the mixed guiding channel 261, the first guiding channel 262, and the second guiding channel 263 communicate with each other.

[0154] By means of the arc design and protrusion, the air flow contact area is increased, the resistance and eddy current are reduced, and the mixing efficiency is improved. Through the inlet 267, mixing can be carried out at the initial stage when the two air flows converge, improving the mixing efficiency.

[0155] It can be understood that, in order to ensure the connectivity performance between multiple guiding channels, the angle between the flow direction of the output port of the first guiding channel 262 and the flow direction of the output port of the mixing guiding channel 261 can be the same as the angle between the flow direction of the output port of the second guiding channel 263 and the flow direction of the output port of the mixing guiding channel 261.

[0156] The aforementioned first angle refers to the angle between the flow direction of the output port of the first guiding channel 262 and the flow direction of the output port of the mixing guiding channel 261, or refers to the angle between the flow direction of the output port of the second guiding channel 263 and the flow direction of the output port of the mixing guiding channel 261. The content of the first angle has been described in the foregoing text and will not be elaborated herein.

[0157] Refer to Figure 8 , in some embodiments, the air flow circulation assembly 200 further includes a second guiding structure 270. The second guiding structure 270 is located in the air mixing channel 203 and is used to change the flow direction of the air flow in the air mixing channel 203 multiple times.

[0158] By changing the air flow direction multiple times, the mixing effect of the air flow can be enhanced, ensuring the uniformity and stability of the air flow, so as to improve the uniformity of the physical parameters of the output air flow.

[0159] In some embodiments, the second guiding structure 270 is formed with a first flow direction changing channel 271. The first flow direction changing channel 271 is close to the input port 203a of the air mixing channel, and the flow direction of the first flow direction changing channel 271 is different from the flow direction of the air mixing channel 203.

[0160] By changing the flow direction, the disturbance and mixing effect of the air flow are increased, ensuring the uniformity and stability of the air flow, so as to improve the uniformity of the storage environment.

[0161] Refer to Figure 8 , in some embodiments, the second guiding structure 270 includes a first flow direction changing plate 273. The first flow direction changing plate 273 is located at the output port of the first guiding structure 260. The number of the first flow direction changing plates 273 is multiple, and the multiple first flow direction changing plates 273 are arranged at intervals in the air mixing channel 203. A first flow direction changing channel 271 is formed between two adjacent first flow direction changing plates 273; the extending direction of the surface of the first flow direction changing plate 273 intersects with the flow direction of the air mixing channel 203.

[0162] In this way, the air flow passing through the first diversion channel 271 flows along the first direction A, and the flow direction of the air mixing channel 203 is the second direction B. The first direction A is different from the second direction B, that is, they intersect. Therefore, the air flow flowing along the first direction A and the air flow flowing along the second direction B can be mixed.

[0163] By changing the flow direction, the disturbance and mixing effect of the air flow are increased, ensuring the uniformity and stability of the air flow to improve the uniformity of the storage environment.

[0164] In some embodiments, the angle between the flow direction of the first diversion channel 271 and the flow direction of the air mixing channel 203 is an acute angle, that is, the angle between the first direction A and the second direction B is an acute angle.

[0165] It can be understood that if the angle between the first direction A and the second direction B is an obtuse angle, the first direction A is in the opposite direction of the second direction B, and the resistance between the flow direction of the first diversion channel 271 and the flow direction of the air mixing channel 203 is relatively large, which will affect the flow of the air flow in the air mixing channel 203.

[0166] Refer to Figure 8 , in some embodiments, the flow direction of the first diversion channel 271 is perpendicular to the flow direction of the air mixing channel 203. That is, the angle between the first direction A and the second direction B is a right angle. At this time, the contact area between the air flow passing through the first diversion channel 271 and the air flow not passing through the first diversion channel 271 is relatively large. In this way, the mixing degree between the air flow passing through the first diversion channel 271 and the air flow not passing through the first diversion channel 271 is relatively high, which can improve the mixing effect of the two air flows in the air mixing channel 203.

[0167] Refer to Figure 9 , in some embodiments, the second guiding structure 270 is formed with a plurality of first diversion channels 271, and the flow directions of the plurality of first diversion channels 271 are different from each other. That is, the air flow directions in each of the first diversion channels 271 are different.

[0168] Through the above settings, the mixing of the air flow can also be achieved between adjacent first diversion channels 271, which can improve the disturbance effect and mixing effect of the air flow.

[0169] Refer to Figure 8 , in some embodiments, the second guiding structure 270 is formed with a plurality of first diversion channels 271, and the flow directions of the plurality of first diversion channels 271 are the same. That is, the air flow directions in each of the first diversion channels 271 are the same, which can ensure that the second guiding structure 270 can output an air flow with a consistent flow path, improving the uniformity and stability of the air flow.

[0170] In some embodiments, the first flow deflector 273 is configured to make the air flow in the first flow deflection channel 271 and change the Reynolds number of the air flow until the flow state of the air flow becomes turbulent.

[0171] It can be understood that if the flow state of the air flow is turbulent, it means that the air flow output from the first channel 201 and the air flow output from the second channel 202 flow in an irregular and chaotic manner, and the two air flows are strongly mixed, so that the second guiding structure 270 can enhance the mixing degree of the air flow, ensure the uniformity and stability of the air flow, and improve the uniformity of the storage environment.

[0172] In some embodiments, according to Re = ρvL0 / μ, where Re is the Reynolds number required for the flow state of the air flow to be turbulent, ρ is the density of the air flow, v is the flow velocity of the air flow, L0 is the characteristic length required for the flow state of the air flow to become turbulent, and μ is the dynamic viscosity of the air flow. According to the above content, when the conditions such as density, flow velocity, and dynamic viscosity remain unchanged, the Reynolds number is proportional to the characteristic length. Therefore, by adjusting the characteristic length, the Reynolds number of the air flow can be changed.

[0173] It can be understood that when the Reynolds number of the air flow is low (for example, less than 2000), the flow state of the air flow is usually laminar. Therefore, in order to make the air flow transform into a turbulent state in the first flow deflection channel 271, it is necessary to increase the Reynolds number of the air flow.

[0174] Exemplarily, if the Reynolds number of the air flow reaches 2300, that is, Re = 2300 can effectively trigger the turbulence of the air flow. In this example, assuming v = 6m / s, μ = 0.0000179Pa.s, ρ = 1.29, at this time, L0 = 5.3mm is obtained. That is, if the extension length of the first flow deflector 273 is 5.3mm, the turbulence of the air flow can be triggered, thereby enhancing the mixing degree of the air flow.

[0175] It should be noted that the above data are only examples and can be adjusted according to the actual situation.

[0176] In some embodiments, the actual extension length of the first flow deflector 273 is L, and the relationship between L and L0 is: L0*0.4 < L < L0*1.6.

[0177] It can be understood that a reasonable ratio helps the air flow to complete the change of the air flow state in the first flow deflection channel 271.

[0178] When the first flow deflector 273 is at the above ratio, the first flow deflector 273 can effectively change the flow state of the air flow, so that the flow state of the air flow is turbulent, thereby improving the mixing degree of the air flow. If L is less than the above ratio, the first flow deflector 273 is short and cannot increase the Reynolds number of the air flow, and thus cannot trigger turbulence; if L is greater than the above ratio, the first flow deflector 273 is long, and the flow resistance of the air flow increases, thereby affecting the flow of the air flow in the first flow deflection channel 271.

[0179] In some embodiments, the relationship between L and L0 is: L0*0.5 ≤ L ≤ L0*1.5. At this time, L0 can be an integer. On this basis, L can take half of L0. At this time, while achieving turbulence, it is convenient to process the first flow deflector 273 with an integer length, reducing the production accuracy and assembly accuracy of the first flow deflector 273.

[0180] In some embodiments, the shape of the first flow deflector 273 can be arbitrary. Exemplarily, the first flow deflector 273 can be a plate body or a column body. Another exemplarily, the end face of the first flow deflector 273 can be circular, rectangular, or rounded rectangular, etc.

[0181] It can be understood that the aforementioned second angle refers to the included angle between the flow direction of the first flow deflection channel 273 (i.e., the first direction A) and the flow direction of the air mixing channel 203 (i.e., the second direction B). The content of the second angle has been described above and will not be elaborated here.

[0182] Refer to Figure 9 , in some embodiments, when the surface extension directions of multiple first flow deflectors 273 are the same, the flow directions of multiple first flow deflection channels 271 are the same. That is, the air flow directions in each first flow deflection channel 271 are the same, which can ensure that the second guiding structure 270 can output air flow with a consistent flow path, improving the uniformity and stability of the air flow.

[0183] Refer to Figure 10 , in some embodiments, along the surface extension direction of the first flow deflector 273, the length of the first flow deflector 273 is L, and the distance between two adjacent first flow deflectors 273 is S1. The relationship between L and S1 is: L < S1 < L*5.

[0184] It should be noted that the distance S1 can affect the flow space size of the air flow between two adjacent first flow deflectors 273.

[0185] It can be understood that a reasonable distance S1 helps the air flow to be fully mixed between adjacent first flow deflection plates 273, improving the mixing efficiency. If S1 is less than the above ratio, the distance between two adjacent first flow deflection plates 273 is too small, which may cause the air flow to fail to enter the first flow deflection channel 271 smoothly, thereby affecting the air flow; if S1 is greater than the above ratio, the distance between two adjacent first flow deflection plates 273 is too large, and the flow velocity of the air flow introduced into the first flow deflection channel 271 is relatively low, thereby affecting the Reynolds number of the air flow, and thus the change in the air flow state cannot be achieved.

[0186] Referring to Figure 10 , in some embodiments, along the extending direction of the surface of the first flow deflection plate 273, the length of the first flow deflection plate 273 is L, and the distance between two adjacent first flow deflection plates 273 is S1. The relationship between L and S1 is: L*2 ≤ S1 ≤ L*4.

[0187] If S1 is between one times L and two times L, although the flow state of the air flow can be changed, the flow path of the air flow is short, and it is possible that only the flow state of part of the air flow changes; if S1 is between four times L and five times L, although the flow path of the air flow is sufficient to ensure that the flow states of all the air flow change, there is also a possibility that the air flow cannot enter the second flow deflection channel 272 smoothly.

[0188] In some embodiments, the second guiding structure 270 forms a second flow deflection channel 272. The second flow deflection channel 272 is located downstream of the first flow deflection channel 271, and the flow direction of the second flow deflection channel 272 is the same as the flow direction of the air mixing channel 203, that is, the air flow passing through the second flow deflection channel 272 also flows along the second direction B. In this way, when the first flow deflection channel 271 outputs the air flow, the second flow deflection channel 272 can change the air flow output by the first flow deflection channel 271 and mix it again; at the same time, the second flow deflection channel 272 can provide a guiding effect to improve the uniformity of the air flow, ensuring that the air mixing channel 203 can output an air flow with a high mixing degree and high uniformity.

[0189] Referring to Figure 10 , in some embodiments, the second guiding structure 270 further includes second flow deflection plates 274. The second flow deflection plates 274 are located at the output ports of the first flow deflection plates 273. The number of the second flow deflection plates 274 is multiple, and the multiple second flow deflection plates 274 are arranged at intervals in the air mixing channel 203. A second flow deflection channel 272 is formed between two adjacent second flow deflection plates 274; the extending direction of the surface of the second flow deflection plates 274 is the same as the flow direction of the air mixing channel 203.

[0190] In some embodiments, the second flow deflector 274 is configured to cause the air flow to flow in the second flow deflection channel 272 and change the Reynolds number of the air flow until the flow state of the air flow changes from turbulent flow to laminar flow.

[0191] It can be understood that, according to the above content, when the Reynolds number of the air flow is low (for example, less than 2000), the flow state of the air flow is usually laminar flow. Therefore, in order to enable the air flow to change to a laminar flow state in the second flow deflection channel 272, it is necessary to reduce the Reynolds number of the air flow.

[0192] It can be understood that if the flow state of the air flow is laminar flow, it means that the second flow deflector 274 can receive the air flow output from the first flow deflection channel 273 and flow in a parallel path to improve the flow consistency of the air flow in the air mixing channel 203, thereby ensuring the uniformity and stability of the air flow output and improving the uniformity of the storage environment.

[0193] Exemplarily, the extension length of the second flow deflector 274 is less than the extension direction of the first flow deflector 273, which can effectively reduce the Reynolds number of the air flow.

[0194] Another exemplarily, no structure is provided between the second flow deflector 274 and the first flow deflector 273, that is, the air flow enters the mixing channel 203 after passing through the first flow deflection channel 271. Since the maximum aperture that the mixing channel 203 can pass through the air flow is much larger than the maximum aperture of the first flow deflection channel 271, the density of the air flow decreases rapidly, and the Reynolds number of the air flow can also be reduced.

[0195] Refer to Figure 10 , in some embodiments, when the surface extension direction of the first flow deflector 273 is perpendicular to the flow direction of the air mixing channel 203, the minimum distance between the adjacent first flow deflector 273 and the second flow deflector 274 is S2, and the relationship between L and S2 is: L < S2 < L * 6.

[0196] It should be noted that the distance S2 can affect the flow space between the first flow deflector 273 and the second flow deflector 274.

[0197] It can be understood that a reasonable distance S2 helps the air flow to change the flow state between the first flow deflector 273 and the second flow deflector 274. If S2 is less than the above ratio, the distance between the first flow deflector 273 and the second flow deflector 274 is too small to effectively change the flow state of the air flow, and thus the output of the laminar air flow cannot be achieved; if S2 is greater than the above ratio, the distance between the first flow deflector 273 and the second flow deflector 274 is too large, which may cause the air flow to not smoothly enter the second flow deflection channel 272, thereby affecting the flow of the air flow.

[0198] In some embodiments, along the flow direction of the air mixing channel 203, the distance between the adjacent first flow direction changing plate 273 and the second flow direction changing plate 274 is S2, and the relationship between L and S2 is: L * 2 ≤ S2 ≤ L * 5.

[0199] If S2 is between one time of L and two times of L, although the flow state of the air flow can be changed, the flow path of the air flow is short, and there may be a situation where only the flow state of part of the air flow is changed; if S1 is between five times of L and six times of L, although the flow path of the air flow is sufficient to ensure that the flow state of all the air flow is changed, there is also a possibility that the air flow cannot smoothly enter the second flow direction changing channel 272.

[0200] It can be understood that when the air flow circulation assembly 200 includes the first guiding structure 260 and the second guiding structure 270, the air flow process is as follows:

[0201] First, the air flow in the storage cavity 101 enters the first channel 201 and the second channel 202 respectively through the input ports of the first channel 201 and the second channel 202 under the influence of the fan 250. Then, the air flow in the first channel 201 enters the mixed guiding channel 261 through the first guiding channel 262. At the same time, the air flow in the second channel 202 enters the mixed guiding channel 261 through the second guiding channel 263. Then, the first guiding structure 260 changes the air flow direction for preliminary mixing and outputs it to the air mixing channel input port 203a. Then, the air flow passes through the first flow direction changing channel 271, and the air flow direction changes, and the air flow is mixed again. Then, the air flow passes through the second flow direction changing channel 272 or passes through the short air mixing channel and then passes through the second flow direction changing channel 272. The second flow direction changing channel 272 is used to guide the air flow to the air mixing channel output port 203b. Finally, the air flow enters the storage cavity 101 through the air mixing channel output port 203b to form an air flow cycle.

[0202] The third guiding structure 280 is communicated with the air mixing channel output port 203b and is used to receive the air flow output by the second guiding structure 270 and change the flow direction so as to output to the storage cavity 101.

[0203] Through the above-mentioned air flow circulation assembly 200 provided with the first guiding structure 260, the second guiding structure 270 and the third guiding structure 280, the mixing degree of the air flow is increased, the mixing efficiency and the mixing effect of the air flow are increased, so that the error between the air flow received by the storage cavity 101 and the target air flow is small, and high-precision temperature adjustment and humidity adjustment can be realized, which is beneficial to forming a storage condition with constant physical parameters, and thus is beneficial to item storage.

[0204] Refer to Figure 8, in some embodiments, the third guiding structure 280 is connected to the air mixing channel outlet 203b, and the aperture of the outlet of the third guiding structure 280 is larger than that of the air mixing channel outlet 203b.

[0205] By increasing the aperture of the outlet, the flow rate of the air flow can be reduced, achieving soft air output and ensuring a relatively stable and uniform air flow circulation in the storage cavity 101.

[0206] Refer to Figure 8 , in some embodiments, the third guiding structure 280 is formed with a first guiding channel 281, the first guiding channel 281 is connected to the air mixing channel outlet 203b, and the aperture of the outlet of the first guiding channel 281 is larger than that of the air mixing channel outlet 203b. By increasing the aperture of the outlet, the flow rate of the air flow can be reduced, achieving soft air output and ensuring a relatively stable and uniform air flow circulation in the storage cavity 101.

[0207] In some embodiments, the third guiding structure 280 is formed with a second guiding channel 282, the second guiding channel 282 is connected to the air mixing channel outlet 203b, and the aperture of the outlet of the second guiding channel 282 is larger than that of the air mixing channel outlet 203b. By increasing the aperture of the outlet, the flow rate of the air flow can be reduced, achieving soft air output and ensuring a relatively stable and uniform air flow circulation in the storage cavity 101.

[0208] In some embodiments, the aperture of the outlet of the first guiding channel 281 is different from that of the outlet of the second guiding channel 282. Through the design of different aperture sizes of the outlets, it is ensured that the air flow can be distributed according to requirements when leaving the air mixing channel 203, the flow rate of the air flow can be reduced, and soft air output at different degrees can be achieved.

[0209] In some embodiments, the aperture of the outlet of the first guiding channel 281 can be larger than that of the outlet of the second guiding channel 282, or can also be smaller than that of the outlet of the second guiding channel 282.

[0210] It can be understood that a larger aperture of the outlet can achieve a greater degree of soft air output, and a smaller aperture of the outlet can achieve a smaller degree of soft air output. Through the above settings, the storage box 10 can adjust the positions of the first guiding channel 281 and the second guiding channel 282 according to the stored items to match items with different requirements, so as to perform adaptive soft air output.

[0211] In some embodiments, the ratio between the aperture of the outlet of the first guiding channel 281 and the aperture of the outlet of the air mixing channel 203 is greater than or equal to 3.

[0212] When the aperture of the outlet of the first outlet channel 281 is 3 times or more of the aperture of the outlet of the air mixing channel 203b, the air flow velocity will be significantly reduced during output to achieve gentle air output, ensuring relatively stable and uniform air circulation in the storage cavity 101.

[0213] Gentle air output can reduce the direct impact on stored items and protect the integrity of the stored items.

[0214] In some embodiments, the ratio between the aperture of the outlet of the second outlet channel 282 and the aperture of the outlet of the air mixing channel 203b is greater than or equal to 3.

[0215] When the aperture of the outlet of the second outlet channel 282 is 3 times or more of the aperture of the outlet of the air mixing channel 203b, the air flow velocity will be significantly reduced during output to achieve gentle air output, ensuring relatively stable and uniform air circulation in the storage cavity 101.

[0216] Gentle air output can reduce the direct impact on stored items and protect the integrity of the stored items.

[0217] It can be understood that if the aforementioned ratio is too small, the aperture of the outlet of the air mixing channel 203b cannot be effectively increased, and the air output volume cannot reach the standard of gentle air output, and thus gentle air output cannot be effectively achieved.

[0218] Refer to Figure 11 , in some embodiments, the first outlet channel 281 and the second outlet channel 282 can be located at different positions in the storage cavity 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 relatively closer to the items in the storage cavity 101 than the upper channel.

[0219] In some embodiments, the aperture of the outlet of the first outlet channel 281 is larger than the aperture of the outlet of the second outlet channel 282, and the first outlet channel 281 is located below the second outlet channel 282.

[0220] Through the above settings, 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 air flow velocity will be significantly reduced during output to achieve gentle air output, ensuring relatively stable and uniform air circulation in the storage cavity 101.

[0221] In some embodiments, the ratio range between the aperture of the outlet of the first outlet channel 281 and the aperture of the outlet of the second outlet channel 282 is greater than 1 and less than or equal to 3.

[0222] With this ratio, it can be ensured that the flow path of the air flow between the outlet channels is relatively long, increasing the contact area between the air flows and improving the mixing efficiency; at the same time, it is ensured that the air flow blows out gently through the first outlet channel 281, ensuring that the air flow circulation in the storage cavity 101 is relatively stable and uniform.

[0223] It can be understood that if the aforementioned ratio is less than 1, the aperture of the outlet of the first outlet channel 281 is smaller than that of the outlet of the second outlet channel 282. The air flow from the second outlet channel 282 is relatively gentle, but it is farther from the items in the storage cavity 101, and the effect on the items is relatively small; if the aforementioned ratio is greater than 3, the aperture of the outlet of the first outlet channel 281 is too large, causing the air flow velocity in the second outlet channel 282 to be too high, and it may cause the air flow not to pass through the first outlet channel 281.

[0224] In some embodiments, the ratio between the aperture of the outlet of the first outlet channel 281 and the aperture of the outlet of the second outlet channel 282 is 7:3.

[0225] With this ratio, it can be ensured that the flow path of the air flow between the outlet channels is relatively long, increasing the contact area between the air flows and improving the mixing efficiency; at the same time, it is ensured that the air flow blows out gently through the first outlet channel 281, ensuring that the air flow circulation in the storage cavity 101 is relatively stable and uniform.

[0226] It can be understood that if the aforementioned ratio is less than 7 / 3, the proportion of the aperture of the outlet of the first outlet channel 281 is relatively small. The air flow from the second outlet channel 282 is relatively gentle, but it is farther from the items in the storage cavity 101, and the effect on the items is relatively small; if the aforementioned ratio is greater than 7 / 3, the aperture of the outlet of the first outlet channel 281 is too large, causing the air flow velocity in the second outlet channel 282 to be too high, and it may cause the air flow not to pass through the first outlet channel 281.

[0227] Refer to Figure 11 , in some embodiments, when the aforementioned third guiding 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 communicates with the first outlet channel 281, and the second air outlet 208 communicates with the second outlet channel 282.

[0228] In some embodiments, the apertures of the first air outlet 207 and the second air outlet 208 are the same.

[0229] It can be understood that the same aperture can ensure that the flow resistance of the air flow at the two air outlets is the same, avoiding the velocity difference of the air flow at the air outlets, and further ensuring that the flow rate of the air flow at the two air outlets is the same, so as to improve the uniformity and stability of the air flow regulation.

[0230] Refer toFigure 11 , in some embodiments, the air flow circulation component 200 includes the aforementioned decorative panel 210, front cover 220, rear cover 230 and rear plate 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 outlets of the two second channels 202B are in communication. A first channel 201 is formed between the front cover 220 and the rear cover 210. The decorative panel 210 has a first air return opening 205 corresponding to the first channel 201 and two parts of second air return openings 206 corresponding to the two second channels 202B.

[0231] The first air return opening 205 communicates with the middle position of the lower part of the storage cavity 101. The first air return opening 205 may communicate with the auxiliary channel 209.

[0232] First, a part of the air flow a1 in the storage cavity 101 enters the auxiliary channel 209 through the first air return opening 205. After filling the air return cavity 231 between the front cover 220 and the rear cover 230, the air flow a1 enters the first channel 201.

[0233] Refer to Figure 12 , the refrigeration component 270 includes an evaporator 310. The evaporator 310 is close to the input port of the first channel 201. The evaporator 310 cools the air flow and dehumidifies it. A second fan 252 is provided on the output side of the evaporator 310. The second fan 252 is a centrifugal fan, which can suck the air flow output by the evaporator 271 and direct the air flow to the air mixing channel 203.

[0234] The second air return opening 206 communicates with both sides of the lower part of the storage cavity 101 and is connected to the output side of the humidification component 500. The humidification component 500 can output a humidified air flow a3, which enters the second channel 202B through the second air return opening 206.

[0235] At the same time, another part of the air flow a2 in the storage cavity 101 and the humidified air flow a3 output by the humidification component 500 pass through the second air return opening 206 and enter the two first channels 201 respectively. Each of the two first channels 201 is provided with a first fan 251. The first fan 251 is an axial fan, which can direct the air flow to the air mixing channel 203.

[0236] Among them, two heating components 400 are close to the output port positions of the two second channels 202B to increase the temperature of the air flow flowing through the two second channels 202B. In this way, the first channel 201 outputs a cooled and dehumidified air flow a4, and the second channel 202B outputs a heated and humidified air flow a5.

[0237] Then, the two airflows respectively enter the first guiding channel 262 and the second guiding channel 263 formed by the first guiding structure 260. The velocities of the two airflows change, and preliminary mixing is completed in the mixing guiding channel 261.

[0238] Then, the second guiding structure 270 receives the airflow output by the first guiding structure 270 and passes through the first diversion channel 271. The adjacent first diversion plates 273 form the first diversion channel 271. The first diversion plates 273 can change the Reynolds number of the airflow to change the airflow from a laminar state to a turbulent state, enhancing the mixing degree of the two airflows. The airflow output from the first diversion channel 271 briefly enters the air mixing channel 203 and then enters the second diversion channel 272 of the second guiding structure 270. The adjacent second diversion plates 274 form the second diversion channel 272. The second diversion plates 274 can change the airflow from a turbulent state to a laminar state.

[0239] Then, the third guiding structure 280 receives the airflow a6 output by the second diversion channel 272. The third guiding structure 280 forms a first outlet channel 281 and a second outlet channel 282. The calibers of the outlets of the first outlet channel 281 and the second outlet channel 282 both increase, enabling gentle air outlet of the airflow. The outlet of the first outlet channel 281 is located above the outlet of the second outlet channel 282. The outlet of the first outlet channel 281 is communicated with the first air outlet 207, and the airflow a7 enters the storage cavity 101 through the first air outlet 207. The outlet of the second outlet channel 282 is communicated with the second air outlet 208, and the airflow a8 enters the storage cavity 101 through the first air outlet 207.

[0240] Then, in the air mixing channel 203 of the air circulation assembly 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.

[0241] Between the airflow a7, airflow a8 received by the storage cavity 101 and the released airflow a1, airflow a2, the fluctuations of the physical parameter changes are relatively small. In this way, when the air flow time remains unchanged, the physical parameters of the airflow change multiple times. Compared with single - time changes, the adjustment accuracy of the physical parameters increases, which can reduce the deviation between the actual airflow and the target airflow, facilitating the formation of storage conditions with constant physical parameters. Furthermore, the airflow in the storage cavity 101 can be within a preset range, which is beneficial for item storage.

[0242] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present application.
