TECHNICAL FIELD

[0002] The present disclosure relates to the technical field of storage equipment. In particular, the present disclosure relates to a storage box. BACKGROUND

[0003] With the development of science and technology and the improvement of living standards, people have higher requirements for the storage period of articles, especially for articles that are more demanding on environmental conditions, such as fresh food, cigars, and wine. SUMMARY

[0005] A storage box includes a box body and an air flow circulation assembly. An interior of the box body defines a storage cavity. The air flow circulation assembly has a first channel, a second channel, a mixing channel, and an adjustment assembly. An input port of the first channel is in communication with the storage cavity. An input port of the second channel is in communication with the storage cavity. The mixing channel has a mixing channel input port and a mixing channel output port.

[0035] Some embodiments of the present disclosure will be described hereinafter with reference to the accompanying drawings, in which specific embodiments are shown. It is to be understood that the present disclosure is not limited to the specific embodiments described herein, but encompasses numerous alternatives, modifications, and equivalents. Those skilled in the art will appreciate that the present disclosure is directed to a range of different materials, structures, and methods of operation. Thus, the specific embodiments described herein are illustrative only and not restrictive.

[0036] The use of “adapted to” or “configured to” herein means open and inclusive language that is not limited to devices adapted or configured to perform additional tasks or steps.

[0037] Unless the context clearly requires otherwise, throughout the description and the claims, the words “comprise,” “comprises,” and the like are to be construed in an open, inclusive sense, as opposed to an exclusive or exhaustive sense; that is to say, in the sense of “including, but not limited to.” As used herein in the description of the embodiments of the application, the terms “one embodiment,” “some embodiments,” “exemplary embodiments,” “an example,” “a specific example” or “some examples” are not necessarily to be construed as excluding the presence of other embodiments or examples. The above described terminology is also used as descriptive, not limiting, terminology. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0038] Hereinafter, the terms “first” and “second” are used only for the purpose of description, and can not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with “first” and “second” can explicitly or implicitly include one or more of the features. In the description of the embodiments of the present disclosure, the meaning of “a plurality of” is two or more, unless otherwise specified.

[0039] In the description of the present disclosure, it should be understood that the terms "center", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present disclosure.

[0040] In describing some embodiments, "coupled" and "connected", and their derivatives, are used. For example, the term "connected" can be used to describe some embodiments to indicate that two or more components are in direct physical or electrical contact with each other. For another example, the term "coupled" can be used to describe some embodiments to indicate that two or more components are in direct physical or electrical contact with each other. However, the terms "coupled" or "communicatively coupled" can also mean that two or more components are not in direct contact with each other, but still cooperate or interact with each other. The embodiments disclosed herein are not necessarily limited to the content herein.

[0041] In order to maintain long-term storage and ensure relatively constant storage conditions, the storage box includes a storage cavity, a heater, a heat exchanger and a refrigerator are arranged in the storage cavity, and the storage conditions of the storage cavity are adjusted by controlling the heater, the heat exchanger and the refrigerator. For example, a warm air passage is arranged in the storage box to increase the temperature of the storage cavity.

[0042] However, in the above-mentioned storage box, the difference between the storage environment before and after the change of the electrical element (such as the heater, the heat exchanger and the refrigerator) is large, for example, the difference between the temperature of the storage box before the heater heats the gas inside the storage box and the temperature of the storage box after the heater heats the gas inside the storage box is large, which causes the storage conditions at different positions of the storage box to be different, which is not conducive to the long-term storage of food in the storage box.

[0043] A constant-temperature and constant-humidity cigar cabinet and a control method thereof are disclosed in the related art. Air flows through a first region in which air flow can be heated and a second region in which air flow can be cooled in sequence. The first region can also be connected to a humidifying device, so as to adjust the temperature and humidity of the air in the cigar cabinet. However, the distance between the positions of the heating, humidifying and cooling of the air flow is small, and the influence of the heating process on the cooling process and the influence of the humidifying process on the cooling process are large, so that the temperature and humidity of the cigar cabinet cannot be accurately adjusted, and the actual storage environment and the required environment of the articles are greatly different. In addition, after the temperature and humidity of the air are adjusted, the adjusted air flow and the unadjusted air flow converge when the adjusted air flow enters the region where the articles are located. However, the temperature difference and the humidity difference between the adjusted air flow and the unadjusted air flow are large, so that the uniformity of the overall environment is poor.

[0044] To solve the above problems, some embodiments of the present disclosure provide a storage box. The storage box has a storage cavity and an air flow circulation assembly connected to the storage cavity. The air flow circulation assembly is provided with a first channel, a second channel and a mixed air channel, and includes an adjustment assembly. The air flow in the storage cavity is received through the first channel and the second channel, the physical parameters (such as temperature and humidity) of the air flow in the first channel and the second channel are adjusted by the adjustment assembly, and the air flow output from the first channel and the second channel is mixed through the mixed air channel. In this way, two air flows with different physical parameters are mixed in the mixed air channel. The ventilation volume of the mixed air flow is increased compared with that of the un-mixed air flow, and the physical parameters of the mixed air flow change to the median of the physical parameters of the two air flows. Therefore, the physical parameters of the air flow output from the mixed air channel are between the physical parameters of the air flow in the first channel and the air flow in the second channel, that is, the size of the physical parameters of the air flow output from the air flow circulation assembly is between the physical parameters of the air flow before entering the air flow circulation assembly and the physical parameters of the air flow inside the air flow circulation assembly.

[0045] Compared with the related art, in some embodiments of the present disclosure, the change and fluctuation of the physical parameters between the air flow received by the storage cavity and the air flow released are small. In this way, structural damage caused by drastic changes can be avoided, and the physical parameters of the air flow can be changed twice under the condition that the air flow flowing time remains unchanged. Compared with single change, the adjustment accuracy of the physical parameters is increased, the deviation between the actual air flow and the target air flow is reduced, and the storage condition of the physical parameters of the air flow in the storage cavity is constant, which is beneficial to the storage of articles.

[0046] In some embodiments of the present disclosure, it should be understood that the terms involved have the following meanings:

[0047] Ventilation volume: the volume of air passing through a section per unit time.

[0048] Venturi effect: According to the continuity equation and Bernoulli equation, when the fluid flows through a pipe that is narrower than the original pipe, the kinetic energy of the fluid increases due to the increase in flow rate, and the pressure energy (i.e. the hydrostatic pressure) decreases accordingly. This means that in the narrow part of the converging pipe, the fluid has the highest velocity and the lowest pressure.

[0049] Pre-set range: The storage condition of the stored items in the storage box.

[0050] Laminar flow: refers to the flow of fluid particles along parallel paths or layers without mixing with each other.

[0051] Turbulent flow: refers to the flow of fluid particles in a random and chaotic manner, with strong mixing and vortex within the fluid.

[0052] Referring to FIG. 1, in some embodiments, the storage box 10 comprises a box body 100. The box body 100 is the main structure of the storage box 10, and the interior of the box body 100 forms a cavity for storing items. In this way, the box body 100 can provide a closed storage space to facilitate the control of the environmental conditions inside the storage box 10.

[0053] Referring to FIG. 2, in some embodiments, the storage box 10 can further comprise an inner container 11 arranged in the cavity of the box body 100. The interior of the inner container 11 forms a storage cavity 101.

[0054] In some embodiments, one side of the box body 100 is open to form an opening, and the storage box 10 can further comprise a door body 120 cooperating with the opening to open or close the storage cavity 101. In some embodiments, the door body 120 is a glass door. For example, the door body 120 can be a hollow glass door.

[0055] In some embodiments, the hollow glass door comprises hollow glass and a door frame, the hollow glass is connected with the door frame and located in the door frame, and the door frame is rotatably connected with a rotating part (such as a U-shell) through a pre-installed part.

[0056] In some embodiments, the hollow glass can be low-emissivity glass to improve the thermal insulation performance of the hollow glass door. Here, the low-emissivity glass is, for example, a coated glass with a reflectance greater than or equal to 80% for far infrared rays with a wavelength range of [4.5 μm, 25 μm].

[0057] In some embodiments, the interior of the hollow glass door is a hollow structure, and the hollow structure can be filled with inert gas (such as argon or neon) to further improve the thermal insulation performance of the hollow glass door.

[0058] In some embodiments, the door frame can include a plurality of frame bodies, and the plurality of frame bodies can be combined to form the door frame by using an injection molding process or a splicing method.

[0059] In some embodiments, the door body 120 and the box body 100 can be connected by pre-installed components. The pre-installed components include but are not limited to a hinge shaft sleeve, a connecting corner code, a door body limiting block, and an air assist device. Here, the hinge shaft sleeve has good wear resistance and lubrication performance, which can facilitate the rotation of the hollow glass door relative to the U-shaped shell; the connecting corner code can increase the connection strength of the hollow glass door and the box body 100; the door body limiting block can limit the rotation angle of the hollow glass door; and the air assist device can assist the rotation of the hollow glass door.

[0060] In some embodiments, one side frame of the door body 120 can be rotationally connected to one side frame of the box body 100 near the opening of the box body 100 by using a rotating component.

[0061] Referring to FIG. 3, in some embodiments, the storage box 10 further includes an air flow circulation assembly 200 configured to adjust the air flow in the storage cavity 101. For example, the air flow circulation assembly 200 can adjust the flow rate, ventilation volume, temperature, humidity, or oxygen content of the air flow.

[0062] In some embodiments, the air flow circulation assembly 200 is located outside the box body 100, i.e., the air flow circulation assembly 200 does not occupy the storage cavity 101, so as to facilitate the storage of more items in the storage box 10.

[0063] Referring to FIG. 1, in some embodiments, the air flow circulation assembly 200 is located inside the storage box 10, so as to facilitate the air flow circulation assembly 200 to receive the air flow output from the storage cavity 101 and facilitate the air flow circulation assembly 200 to output the air flow to the storage cavity 101.

[0064] In some embodiments, the air flow circulation assembly 200 has a first channel 201 configured to transport air flow, and the first channel 201 is in communication with the storage cavity 101. The first channel 201 has an input port, for example, a side opening of the first channel 201 through which the air flow enters, and an output port, for example, a side opening of the first channel 201 through which the air flow flows out. The first channel 201 is in communication with the storage cavity 101 through the input port to receive the air flow output from the storage cavity 101.

[0065] In some embodiments, the air flow circulation assembly 200 further has a second channel 202 configured to transport air flow, and the second channel 202 is in communication with the storage cavity 101. The second channel 202 has an input port and an output port. The second channel 202 is in communication with the storage cavity 101 through the input port to receive the air flow output from the storage cavity 101.

[0066] In some embodiments, the air circulation assembly 200 has a mixing passage 203, one side of which is in communication with the first passage 201 and the second passage 202 respectively, and the other side is in communication with the storage cavity 101. The mixing passage 203 is configured to receive the air flows input from the first passage 201 and the second passage 202, and output the mixed air flow to the storage cavity 101 after mixing.

[0067] In some embodiments, referring to FIG. 1, the mixing passage 203 has a mixing passage input port 203a, which is in communication with the output port of the first passage 201 and the output port of the second passage 202 respectively. The mixing passage 203 also has a mixing passage output port 203b, which is in communication with the storage cavity 101.

[0068] It can be understood that the air flow in the first passage 201 and the air flow in the second passage 202 enter the mixing passage 203 and mix in the mixing passage 203. Therefore, the physical parameter of the air flow output by the mixing passage 203 is within the range between the physical parameter of the air flow in the first passage 201 and the physical parameter of the air flow in the second passage 202.

[0069] For example, the physical parameter of the air flow in the first passage 201 is defined as X1, and the physical parameter of the air flow in the second passage 202 is defined as X2. In the case of X1 being less than X2, the range of the physical parameter of the air flow output by the mixing passage 203 is [X1, X2]; in the case of X1 being greater than or equal to X2, the range of the physical parameter of the air flow output by the mixing passage 203 is [X2, X1].

[0070] That is, the physical parameter of the air flow output by the air circulation assembly 200 is within the range between the physical parameter of the air flow received by the air circulation assembly 200 and the physical parameter of the air flow inside the air circulation assembly 200.

[0071] In some embodiments, referring to FIG. 1, the air circulation assembly 200 further comprises a fan 250 configured to drive the air flow. The air circulation assembly 200 is configured to make the first passage 201 and the second passage 202 receive the air flow in the storage cavity 101 by the fan 250, and input the air flows with different physical parameter values output from the first passage 201 and the second passage 202 to the mixing passage 203 for mixing.

[0072] It can be understood that the fan 250 can be an axial fan, and the airflow flows along the axial direction of the fan blade under the action of the axial fan. The fan 250 can also be a centrifugal fan, and the airflow flows along the radial direction of the fan blade under the action of the centrifugal fan. The fan 250 can also be a mixed flow fan, and part of the airflow flows along the axial direction of the fan blade and the other part of the airflow flows along the radial direction of the fan blade under the action of the mixed flow fan.

[0073] In some embodiments, the fan 250 is located in at least one of the first channel 201, the second channel 202 or the mixed air channel 203, so that the airflow output by the storage cavity 101 can enter the airflow circulation assembly 200, and the airflow output by the airflow circulation assembly 200 can flow back to the storage cavity 101, forming an airflow circulation of the storage cavity 101-airflow circulation assembly 200-storage cavity 101.

[0074] Referring to FIG. 4, in some embodiments, the airflow circulation assembly 200 further comprises an adjusting assembly 20 configured to change the physical parameter of the airflow flowing through the adjusting assembly. The physical parameter includes but is not limited to temperature, humidity or oxygen content.

[0075] In some embodiments, the adjusting assembly 20 is located in at least one of the first channel 201 or the second channel 202, that is, the adjusting assembly 20 can adjust the physical parameter of the airflow before entering the mixed air channel 203, for example, the adjusting assembly 20 can increase the temperature of the airflow, decrease the temperature of the airflow, increase the humidity of the airflow, decrease the humidity of the airflow, increase the oxygen content of the airflow or decrease the oxygen content of the airflow.

[0076] It should be noted that in some embodiments of the present disclosure, the shape, position and composition of the first channel 201 and the second channel 202 can be selected according to actual conditions. For example, the second channel 202 can include a plurality of sub-channels in communication, and any two of the plurality of sub-channels are not adjacent in position but in airflow communication.

[0077] It can be understood that after one airflow flows through one of the first channel 201 and the second channel 202 and its physical parameter changes, the one airflow mixes with another airflow flowing through the other of the first channel 201 and the second channel 202 in the mixed air channel 203, and the physical parameter of the mixed airflow changes compared with the physical parameters of the above two airflows. That is, the physical parameter of the mixed airflow in the mixed air channel 203 is different from the physical parameter of the airflow in the first channel 201 and the physical parameter of the airflow in the second channel 202, and further the physical parameter of the mixed airflow in the mixed air channel 203 is also different from the physical parameter of the airflow in the storage cavity 101.

[0078] In some embodiments, the physical parameter is temperature, and the temperature of the air flow in the storage cavity 101 is 0°C, the temperature of the air flow after flowing through the first passage 201 changes to -2°C, and the temperature of the air flow after flowing through the second passage 202 does not change.

[0079] It can be understood that the adjustment assembly 20 can be located in the first passage 201 at this time.

[0080] The air flow in the storage box 10 is divided into two streams, the first stream of air flow after flowing through the first passage 201 has a temperature of -2°C, and the second stream of air flow after flowing through the second passage 202 has a constant temperature. The first stream of air flow and the second stream of air flow after flowing through the first passage 201 and the second passage 202, respectively, are mixed in the air mixing passage 203. In the air mixing passage 203, the air flow with a temperature of -2°C and the air flow with a temperature of 0°C are mixed in the air mixing passage 203, and the air flow with a temperature of -1°C is finally output in the air mixing passage 203. At this time, the physical parameter of the air flow in the air mixing passage 203 is within the range between the physical parameter of the air flow in the first passage 201 and the physical parameter of the air flow in the storage cavity 101.

[0081] In other embodiments, the physical parameter includes temperature and humidity, and the temperature of the air flow in the storage cavity 101 is 0°C, the humidity of the air flow is 1 g / m 3 , the temperature of the air flow after flowing through the first passage 201 changes to -2°C, and the humidity does not change; the temperature of the air flow after flowing through the second passage 202 does not change, and the humidity increases to 1 g / m 3 .

[0082] It can be understood that the adjustment assembly 20 can be located in the first passage 201 and the second passage 202 at this time.

[0083] The air flow in the storage box 10 is divided into two streams, the first stream of air flow after flowing through the first passage 201 has a temperature of -2°C and a constant humidity, and the second stream of air flow after flowing through the second passage 202 has a constant temperature and a humidity of 2 g / m 3 . The first stream of air flow and the second stream of air flow after flowing through the first passage 201 and the second passage 202, respectively, are mixed in the air mixing passage 203. In the air mixing passage 203, the air flow with a temperature of -2°C and the air flow with a temperature of 0°C are mixed, and the air flow with a temperature of -1°C is finally output in the air mixing passage 203; the air flow with a humidity of 1 g / m 3 and the air flow with a humidity of 2 g / m 3 are mixed, and the air flow with a humidity of 1.5 g / m 3 is finally output in the air mixing passage 203. At this time, the physical parameter of the air flow in the air mixing passage 203 is within the range between the physical parameter of the air flow in the first passage 201 and the physical parameter of the air flow in the storage cavity 101.

[0084] As can be seen from the above embodiments, in the case that the air circulation assembly 200 comprises the adjustment assembly 20, the physical parameter of the air stream output by the air mixing channel 203 is between the physical parameter of the air stream in the storage cavity 101 and the physical parameter of the air stream received by the air mixing channel 203.

[0085] In this way, the physical parameter of the air stream released by the storage box 10 is close to the physical parameter of the air stream received by the storage box 10, and the fluctuation of the change in the physical parameter is small during the process that the air stream in the storage box 10 enters the air circulation assembly 200 and is circulated and output. In the case that the air flow time is unchanged, the physical parameter of the air stream changes twice, which increases the adjustment accuracy of the physical parameter compared with the case that the physical parameter of the air stream changes once, reduces the deviation between the physical parameter of the actual air stream and the physical parameter of the target air stream, and is beneficial to form a storage condition with constant physical parameter, so that the physical parameter of the air stream in the storage cavity 101 can be located in a preset range, thereby being beneficial to the storage of the goods.

[0086] Referring to FIG. 4, in some embodiments, when the physical parameter comprises temperature, the adjustment assembly 20 can comprise a refrigeration assembly 300. The refrigeration assembly 300 is located in the first channel 201 and is configured to reduce the temperature of the air stream flowing through the first channel 201 to reduce the temperature of the air stream output by the air mixing channel 203.

[0087] In some embodiments, the refrigeration assembly 300 can also be configured to reduce the humidity of the air stream flowing through the first channel 201 to reduce the humidity of the air stream output by the air mixing channel 203.

[0088] It should be noted that the type of the refrigeration assembly 300 can be selected according to actual conditions.

[0089] In some embodiments, the refrigeration assembly 300 can be a vapor compression refrigeration system. The vapor compression refrigeration system compresses the refrigerant by a compressor, liquefies the refrigerant by heat release in a condenser, and vaporizes the liquefied refrigerant by heat absorption in an evaporator, so as to achieve refrigeration of the surrounding environment of the refrigeration assembly 300. The vapor compression refrigeration system can be applied to a storage box 10 such as a refrigerator, a cold storage, a refrigerated vehicle, a refrigerator, a beverage display cabinet, etc.

[0090] It can be understood that in the case that the refrigeration assembly 300 is a vapor compression refrigeration system, the vapor compression refrigeration system comprises an evaporator 310 (shown in FIGS. 15 and 27), which can vaporize the moisture in the air stream flowing therethrough. Therefore, the refrigeration assembly 300 can complete refrigeration by heat absorption and reduce the humidity of the air stream.

[0091] In other embodiments, the refrigeration assembly 300 can be a semiconductor refrigerator (Thermoelectric Cooler, TEC), which cools the surrounding environment by passing an electric current through a semiconductor material to cause one side of the semiconductor material to absorb heat and the other side to release heat. The semiconductor refrigerator can be applied in the storage box 10, in which case the storage box 10 is, for example, a small storage device such as a portable refrigerator or a car refrigerator.

[0092] In yet other embodiments, the refrigeration assembly 300 can be an absorption refrigeration system, which cools the surrounding environment by an absorption and desorption process of an absorbent (such as water) and a refrigerant (such as ammonia) powered by a heat source (such as natural gas or solar energy). The absorption refrigeration system can be applied in the storage box 10, in which case the storage box 10 is, for example, a solar-powered refrigerator.

[0093] Referring to FIG. 5A, in some embodiments, when the physical parameter comprises temperature, the adjustment assembly 20 can comprise a heating assembly 400, which is located in the second channel 202 and configured to increase the temperature of the airflow flowing through the second channel 202 to increase the temperature of the airflow output by the air mixing channel 203.

[0094] Referring to FIG. 16, in some embodiments, the heating assembly 400 comprises a heater 410, which is configured to heat the surrounding environment.

[0095] The heating assembly 400 further comprises a protective cover 420. The protective cover 420 covers the outside of the heater 410 and is configured to protect the heater 410. The protective cover 420 can prevent damage to the heater 410 from the external environment, and can also prevent high temperatures generated by the heater 410 from causing harm to the surrounding environment and personnel, thereby improving the safety and durability of the storage box 10.

[0096] It should be noted that the type of the heating assembly 400 can be selected according to actual conditions.

[0097] In some embodiments, the heating assembly 400 can be an electric resistance heater, in which an electric current passing through a resistive material generates heat. The electric resistance heater can be used in the storage box 10, in which case the storage box 10 is, for example, a humidor to store cigars and prevent them from getting wet.

[0098] In some embodiments, the heating assembly 400 can be a positive temperature coefficient (PTC) heater. The PTC material increases in temperature after being powered on, and its resistance value also increases to adjust the heating power. The PTC heater can be used in a storage box 10 with constant temperature.

[0099] The protective cover 420 has heat dissipation openings. By providing the heat dissipation openings, air flow can pass through the protective cover 420, thereby achieving heat dissipation and ventilation. The heat dissipation openings can prevent the heater 410 from overheating, thereby improving the efficiency and service life of the heater 410.

[0100] It can be understood that, as shown in FIG. 5B, the heating assembly 400 can be located at the output of the first channel 201, and can heat the air flow passing through the first channel 201.

[0101] Referring to FIG. 6, in some embodiments, when the physical parameter includes humidity, the adjusting assembly 20 can include a humidifying assembly 500, which can increase the humidity of the air flow passing therethrough, and increase the humidity of the air flow output by the air mixing channel 203.

[0102] It should be noted that the type of the humidifying assembly 500 can be selected according to actual conditions.

[0103] In some embodiments, the humidifying assembly 500 can be a natural evaporation humidifier, which utilizes the natural evaporation process of water, and uses a fan to bring moisture into the air, thereby increasing the humidity of the air.

[0104] In other embodiments, the humidifying assembly 500 can be an ultrasonic humidifier, which utilizes ultrasonic oscillation to turn water into fine-particle water mist, and uses a fan to diffuse the water mist into the air, thereby increasing the humidity of the air.

[0105] In yet other embodiments, the humidifying assembly 500 can be an electric heating steam humidifier, which heats water into water vapor by electric heating, and then releases the water vapor into the air, thereby increasing the humidity of the air.

[0106] In yet other embodiments, the humidifying assembly 500 can be a centrifugal humidifier, which utilizes a rotating centrifugal disc to fling water out to form fine-particle water mist, and uses a fan to diffuse the water mist into the air, thereby increasing the humidity of the air.

[0107] In yet other embodiments, the humidifying assembly 500 can be a high-pressure micro-mist humidifier, which pressurizes water by a high-pressure pump, and causes the water to form water mist particles through a nozzle, and the water mist particles evaporate into the air, thereby increasing the humidity of the air.

[0108] Referring to FIG. 6, in some embodiments, the humidifying assembly 500 is located in the second channel 202, and is configured to increase the humidity of the air flow passing through the second channel 202. That is, the humidifying assembly 500 can be installed in the second channel 202, and when the air flow passes through the second channel 202, the humidifying assembly 500 performs humidification processing on the air flow, so as to increase the humidity of the air flow passing through the second channel 202.

[0109] In this way, the humidifying assembly 500 can effectively humidify the airflow flowing therethrough, so as to ensure that the humidity of the airflow can quickly reach (e.g., be greater than or equal to) the expected humidity value when the airflow passes through the second channel 202. In addition, the humidifying assembly 500 is located in the second channel 202, which can make the structure of the conditioning assembly 20 more compact. Moreover, the humidifying assembly 500 can accurately control the humidity of the airflow and reduce humidity fluctuations, so as to improve the humidity stability of the storage environment inside the storage box 10.

[0110] Referring to FIG. 7, in some embodiments, the second channel 202 can include a plurality of sub-channels in communication. For example, the second channel 202 can include a first sub-channel 202A and a second sub-channel 202B, the first sub-channel 202A and the second sub-channel 202B are in communication, and the first sub-channel 202A is located upstream of the second sub-channel 202B.

[0111] It should be noted that the communication of the first sub-channel 202A and the second sub-channel 202B can include various ways. For example, the first sub-channel 202A and the second sub-channel 202B are sequentially connected in a head-to-tail manner. For another example, the first sub-channel 202A and the second sub-channel 202B are both in communication with the storage cavity 101, and the airflow in the storage cavity 101 and the airflow in the first sub-channel 202A can enter the second sub-channel 202B. For another example, the first sub-channel 202A is in communication with the second sub-channel 202B through a pipeline.

[0112] It should be noted that the first channel 201 can also include a plurality of sub-channels. For specific content, reference can be made to the second channel 202 including a plurality of sub-channels in communication, which will not be described here.

[0113] In some embodiments, when the first sub-channel 202A and the second sub-channel 202B are both in communication with the storage cavity 101, the airflow in the storage cavity 101 and the airflow in the first sub-channel 202A can enter the second sub-channel 202B. At this time, the humidifying assembly 500 can be located in the first sub-channel 202A to increase the humidity of the airflow flowing through the first sub-channel 202A and provide humidified airflow to the second sub-channel 202B. The airflow in the storage cavity 101 and the airflow in the second sub-channel 202B can both flow to the first sub-channel 202A.

[0114] By arranging the humidifying assembly 500 outside the second sub-channel 202B, when the humidifying assembly 500 needs to be repaired or replaced, the second channel 202 does not need to be completely disassembled, which can improve the convenience of maintenance.

[0115] Referring to FIG. 8, in some embodiments, when the physical parameter includes the oxygen content, the adjusting assembly 20 can include an oxygen assembly 600 configured to increase the oxygen content of the airflow flowing through the first channel 201 or the second channel 202 to increase the oxygen content of the airflow output by the mixing channel 203, so as to facilitate the storage of items requiring oxygen storage.

[0116] It should be noted that the type of the oxygen assembly 600 can be selected according to actual conditions.

[0117] In some embodiments, the oxygen assembly 600 is an electrochemical oxygen generator that generates oxygen by electrolyzing water. At this time, the storage box 10 can be used to store high-oxygen-demanding medicines or biological samples.

[0118] In other embodiments, the oxygen assembly 600 is an oxygen cylinder and a pressure reducing valve, and oxygen in the oxygen cylinder can be released through the pressure reducing valve. At this time, the storage box 10 can be used to store art or cultural relics for a short period of time.

[0119] In yet other embodiments, the oxygen assembly 600 is a molecular sieve oxygen concentrator that removes nitrogen and other gas components from air through molecular sieve technology to extract oxygen. At this time, the storage box 10 can be used to store food that requires a high-oxygen environment.

[0120] In some embodiments, the position of the oxygen assembly 600 can be diverse. The oxygen assembly 600 can be connected to the first channel 201 or the second channel 202, and can change the oxygen content of the airflow flowing through the first channel 201 or the second channel 202.

[0121] Referring to FIG. 9, it can be understood that the airflow circulation assembly 200 can include a plurality of adjusting assemblies 20.

[0122] In some embodiments, the adjusting assembly 20 can include a refrigeration assembly 300 and a humidification assembly 500, and the refrigeration assembly 300 is arranged in the first channel 201 and the humidification assembly 500 is arranged in the second channel 202. The refrigeration assembly 300 can reduce the temperature of the airflow flowing through the first channel 201, and the humidification assembly 500 can increase the humidity of the airflow output by the second channel 202. At this time, the storage box 10 can be used to store items requiring low-temperature and high-humidity storage (such as fruits or vegetables).

[0123] In some embodiments, the adjusting assembly 20 can include a refrigeration assembly 300 and a heating assembly 400, and the refrigeration assembly 300 is arranged in the first channel 201, and the heating assembly 400 is arranged in the second channel 202. The refrigeration assembly 300 can reduce the temperature of the air flow flowing through the first channel 201, and the heating assembly 400 can increase the temperature of the air flow output by the second channel 202. In this way, the storage box 10 has two temperature adjustment modes, which increases the accuracy of temperature adjustment and increases the temperature adjustment range. At this time, the storage box 10 can be used for storing cigars and red wine.

[0124] In some embodiments, the adjusting assembly 20 can include a refrigeration assembly 300, a humidification assembly 500, and a heating assembly 400, and the refrigeration assembly 300 is arranged in the first channel 201, and the heating assembly 400 and the humidification assembly 500 are arranged in the second channel 202. 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 humidification 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 modes, which improves the accuracy of temperature adjustment, but also can adjust the humidity. At this time, the storage box 10 can be used for storing items that have high storage requirements for temperature and humidity, such as cigars.

[0125] In the above embodiments, in the case where the refrigeration assembly 300 includes an evaporator 310, the circulation process of the air flow in the storage box 10 is as follows:

[0126] One of the air flows in the storage cavity 101 enters the second channel 202, and the heating assembly 400 in the second channel 202 can increase the temperature of the air flow flowing therethrough. The humidification assembly 500 located upstream of the second channel 202 outputs humidified air flow to the second channel 202. Another air flow enters the first channel 201, and the refrigeration assembly 300 in the first channel 201 can reduce the temperature of the air flow flowing through the first channel 201. And the humidification assembly 500 located upstream of the first channel 201 outputs air flow with higher humidity to the first channel 201. Then, the second channel 202 outputs the heated and humidified air flow, and the first channel 201 outputs the cooled air flow. Then, the air flow output by the first channel 201 and the air flow output by the second channel 202 receive the two air flows through the air mixing channel input port 203a, and mix in the air mixing channel 203. Then, the mixed air flow is output to the storage cavity 101 through the air mixing channel output port 203b.

[0127] It should be noted that the humidity of the air flow received by the storage cavity 101 is increased compared to the humidity of the air flow before the circulation of the storage cavity 101. Therefore, the circulation process of the air flow in the storage cavity 101 entering the air flow circulation assembly 200 again is as follows:

[0128] The air flow in the storage cavity 101 enters the first channel 201, and the air flow received by the first channel 201 has a certain moisture. Then, the evaporator 310 located in the first channel 201 can vaporize the moisture in the air flow flowing through the first channel 201, so as to complete refrigeration by absorbing heat and reduce the humidity of the air flow. Therefore, the evaporator 310 can realize the functions of dehumidification and cooling of the air flow flowing therethrough at the same time. This double regulation function enables the storage box 10 to accurately control the temperature and humidity of the storage environment, and meets the storage requirements of the articles (such as cigars) which have high requirements on temperature and humidity.

[0129] Through the cooling and dehumidification effect of the evaporator 310, the physical parameters of the air flow output by the first channel 201 are relatively stable. In the case that the air flow output by the first channel 201 and the air flow output by the second channel 202 are mixed in the air mixing channel 203, the uniformization of the physical parameters of the air flow can be better realized, the fluctuation of the physical parameters of the air flow is reduced, and the adjustment accuracy of the physical parameters of the air flow is improved.

[0130] In addition, the evaporator 310 not only can complete the cooling of the air flow in the first channel 201, but also can realize the dehumidification function of the air flow by vaporizing the moisture, thereby improving the efficiency of the adjustment assembly 20 in adjusting the physical parameters of the air flow. In this way, the storage box 10 can reach the temperature and humidity conditions required by the stored articles in a shorter time, thereby improving the efficiency.

[0131] Referring to FIG. 10, it can be understood that, on the basis of the above-mentioned embodiments, the adjustment assembly 20 can further include an oxygen assembly 600, which can change the oxygen content of the air flow. In this way, the storage box 10 can be used for storing articles such as cigars, and maintaining constant temperature, humidity and oxygen content in the storage cavity 101, thereby avoiding deterioration of the articles.

[0132] In some embodiments, the number of the fan 250 can be adjusted according to actual conditions, for example, the air flow circulation assembly 200 can include at least one fan 250.

[0133] In the case that the number of the fan 250 is one, the fan 250 can be located in the first channel 201, or located in the second channel 202, or located in the air mixing channel 203.

[0134] Referring to FIG. 5A, in some embodiments, the fan 250 can include a first fan 251 located in the first passage 201 and configured to drive the airflow in the first passage 201 to flow to the air mixing passage 203. At this time, the second passage 202 is not provided with the fan 250, and thus the ventilation amount of the airflow into the second passage 202 is less than the ventilation amount of the airflow into the first passage 201. In the above-mentioned embodiments, when the refrigeration assembly 300 is provided in the first passage 201, the cooling airflow mixed in the air mixing passage 203 is more, and the temperature of the airflow output from the air mixing passage 203 to the storage cavity 101 is lower (e.g., less than the second preset temperature), which can be applied to the storage of the articles that need to be rapidly cooled.

[0135] Referring to FIG. 6, in some embodiments, the fan 250 can include a second fan 252 located in the second passage 202 and configured to drive the airflow in the second passage 202 to flow to the air mixing passage 203. At this time, the first passage 201 is not provided with the fan 250, and thus the ventilation amount of the airflow into the first passage 201 is less than the ventilation amount of the airflow into the second passage 202. In the above-mentioned embodiments, when the refrigeration assembly 300 is provided in the first passage 201, the cooling airflow mixed in the air mixing passage 203 is less, and the temperature of the airflow output from the air mixing passage 203 to the storage cavity 101 is higher (e.g., greater than the first preset temperature), which can be applied to the storage of the articles that do not need to be cooled.

[0136] Referring to FIG. 4, in some embodiments, the fan 250 can include an air mixing fan 253 located in the air mixing passage 203, and the air mixing fan 253 is configured to suck the airflows in the first passage 201 and the second passage 202, so that the airflow in the first passage 201 and the airflow in the second passage 202 can enter the air mixing passage 203 at the same time to be mixed in the air mixing passage 203.

[0137] When the number of the fan 250 is multiple, the multiple fans 250 can operate at the same time to improve the circulation speed of the airflow between the airflow in the storage cavity 101 of the box body 100 and the airflow circulation assembly 200. It should be noted that the fan 250 can be provided in at least one of the first passage 201, the second passage 202, and the air mixing passage 203.

[0138] Referring to FIG. 8, in some embodiments, the air fans 250 can include a first air fan 251 and a second air fan 252, the first air fan 251 is located in the first channel 201 and is configured to drive the airflow in the first channel 201 to flow to the air mixing channel 203; the second air fan 252 is located in the second channel 202 and is configured to drive the airflow in the second channel 202 to flow to the air mixing channel 203. In this way, multiple air fans 250 work simultaneously, which can improve the circulation speed of the airflow between the storage cavity 101 and the airflow circulation assembly 200.

[0139] Referring to FIG. 7, in some embodiments, the air fans 250 can include a first air fan 251 and an air mixing fan 253, the first air fan 251 is located in the first channel 201 and is configured to drive the airflow in the first channel 201 to flow to the air mixing channel 203; the air mixing fan 253 is located in the air mixing channel 203 and is configured to suck the airflow in the first channel 201 and the second channel 202 into the air mixing channel 203. In this way, multiple air fans 250 work simultaneously, which can improve the circulation speed of the airflow between the storage cavity 101 and the airflow circulation assembly 200.

[0140] Referring to FIG. 9, in some embodiments, the air fans 250 include a second air fan 252 and an air mixing fan 253, the second air fan 252 is arranged in the second channel 202 and is configured to drive the airflow in the second channel 202 to flow to the air mixing channel 203; the air mixing fan 253 is arranged in the air mixing channel 203 and is configured to suck the airflow in the first channel 201 and the second channel 202. In this way, multiple air fans 250 work simultaneously, which can improve the circulation speed of the airflow between the storage cavity 101 and the airflow circulation assembly 200.

[0141] Referring to FIG. 10, in some embodiments, the air fans 250 include a first air fan 251, a second air fan 252 and an air mixing fan 253, the first air fan 251 is located in the first channel 201 and is configured to drive the airflow in the first channel 201 to flow to the air mixing channel 203; the second air fan 252 is located in the second channel 202 and is configured to drive the airflow in the second channel 202 to flow to the air mixing channel 203; the air mixing fan 253 is located in the air mixing channel 203 and is configured to suck the airflow in the first channel 201 and the second channel 202. In this way, multiple air fans 250 work simultaneously, which can improve the circulation speed of the airflow between the storage cavity 101 and the airflow circulation assembly 200.

[0142] Referring to FIG. 12, in some embodiments, the storage box 10 further includes a first sensor 710, the first sensor 710 is arranged in the storage cavity 101 and is configured to monitor the physical parameters of the airflow in the storage cavity 101.

[0143] It can be understood that the first sensor 710 can be configured to sense the physical parameter of the air in the vicinity, i.e., the physical parameter of the location where the first sensor 710 is located, which is equivalent to obtaining the physical parameter of the air flow in the storage cavity 101.

[0144] The storage box 10 further comprises a second sensor 720, which is arranged in the air flow circulation assembly 200 and is configured to monitor the physical parameter of the air flow in the air flow circulation assembly 200.

[0145] It should be noted that, since the air flow circulation assembly 200 is provided with the air mixing channel 203, the first channel 201 and the second channel 202, the second sensor 720 can be arranged in at least one of the air mixing channel 203, the first channel 201 and the second channel 202.

[0146] It can be understood that, in order to improve the detection accuracy of the physical parameter of the air flow, the second sensor 720 can be located downstream of the adjustment assembly 20.

[0147] In some embodiments, referring to FIG. 4, in the case that the storage box 10 comprises one second sensor 720 and the adjustment assembly 20 is located in the first channel 201, the second sensor 720 can be arranged close to the output port of the first channel 201, and the second sensor 720 can also be arranged in the air mixing channel 203.

[0148] Referring to FIG. 5A, in the case that the storage box 10 comprises one second sensor 720 and the adjustment assembly 20 is located in the second channel 202, the second sensor 720 can be arranged close to the output port of the second channel 202, and the second sensor 720 can also be arranged in the air mixing channel 203.

[0149] In other embodiments, referring to FIG. 7, in the case that the storage box 10 comprises two second sensors 720, one of the two second sensors 720 can be arranged in the air mixing channel 203, and the other second sensor 720 can be arranged downstream of the adjustment assembly 20.

[0150] In still other embodiments, referring to FIG. 9, in the case that the storage box 10 comprises three second sensors 720, the three second sensors 720 are respectively arranged in the air mixing channel 203, the output port of the first channel 201 and the output port of the second channel 202.

[0151] Referring to FIG. 11, the storage box 10 further comprises a monitoring assembly 700. The monitoring assembly 700 comprises the first sensor 710 and the second sensor 720.

[0152] It can be understood that the types of the first sensor 710 and the second sensor 720 can be adapted according to the type of the adjustment assembly 20.

[0153] For example, in the case that the adjusting assembly 20 comprises the refrigeration assembly 300 or the heating assembly 400, the first sensor 710 and the second sensor 720 can both be temperature sensors to obtain the temperature of the air flow in the storage cavity 101 and the temperature of the air flow in the air flow circulation assembly 200, respectively.

[0154] For another example, in the case that the adjusting assembly 20 comprises the humidification assembly 500, the first sensor 710 and the second sensor 720 can both be humidity sensors to obtain the humidity of the air flow in the storage cavity 101 and the humidity of the air flow in the air flow circulation assembly 200, respectively.

[0155] For yet another example, in the case that the adjusting assembly 20 comprises the oxygen assembly 600, the first sensor 710 and the second sensor 720 can both be oxygen concentration sensors to obtain the oxygen concentration of the air flow in the storage cavity 101 and the oxygen concentration of the air flow in the air flow circulation assembly 200, respectively.

[0156] It can be understood that, in the case that the adjusting assembly 20 comprises the humidification assembly 500, and one or both of the refrigeration assembly 300 or the heating assembly 400, the first sensor 710 and the second sensor 720 can both be temperature and humidity sensors to obtain the temperature and humidity of the air flow in the storage cavity 101 and the temperature and humidity of the air flow in the air flow circulation assembly 200, respectively.

[0157] The storage box 10 further comprises a controller 900 coupled with the first sensor 710 and the second sensor 720, and configured to obtain the physical parameters of the air flow in the storage cavity 101 and the air flow in the air flow circulation assembly 200.

[0158] It can be understood that the type of the controller 900 can be selected according to actual conditions.

[0159] In some embodiments, the controller 900 is a microcontroller unit (MCU), which has high integration and low power consumption. The controller 900 can also be a programmable logic controller (PLC), which has high reliability and expandability. The controller 900 can also be an embedded system, in which case the controller 900 can process complex data and multitasking. The controller 900 can also be a single-board computer (such as Raspberry Pi), in which case the controller 900 can be connected to the Internet for data processing.

[0160] In some embodiments, the controller 900 is configured to control the working parameters of the air blower 250 and the adjustment assembly 20 according to the physical parameters of the air flow acquired from the first sensor 710 and the second sensor 720.

[0161] In this way, the storage box 10 can monitor the physical parameters of the air flow at different positions in the storage cavity 101 through the controller 900, so as to adjust the working parameters of the adjustment assembly 20 according to the stored items.

[0162] In some embodiments, in the case that the adjustment assembly 20 comprises the heating assembly 400, the refrigeration assembly 300 and the humidification assembly 500, the storage box 10 can have multiple working modes.

[0163] In some embodiments, the controller 900 has a first mode, in which the controller 900 controls the air blower 250 to work and controls the heating assembly 400, the refrigeration assembly 300 and the humidification assembly 500 not to work. At this time, only the air blower 250 works, and the air blower 250 can drive the air flow to circulate so that the air flow circulates between the storage cavity 101 and the air flow circulation assembly 200. In this way, the air flow can flow through different positions in the storage box 10, and the physical parameters of the air flow at different positions can be ensured to be consistent, so as to realize the uniformity of the physical parameters of the air flow at different positions.

[0164] In some embodiments, the controller 900 has a second mode, in which the controller 900 controls the air blower 250 to work and controls one of the heating assembly 400, the refrigeration assembly 300 and the humidification assembly 500 to work. At this time, the storage box 10 is suitable for scenarios requiring single adjustment, for example, scenarios requiring heating, refrigeration or humidification of the air in the storage cavity 101, so that energy consumption can be saved.

[0165] For example, in the case that the temperature in the storage cavity 101 is relatively high, the controller 900 can only control the refrigeration assembly 300 to work, and the refrigeration assembly 300 can absorb heat to reduce the temperature in the storage cavity 101.

[0166] In the case that the refrigeration assembly 300 comprises an evaporator 310 and the humidity in the storage cavity 101 is relatively high (e.g., greater than a first preset humidity) and the temperature is relatively high, the controller 900 can also only control the refrigeration assembly 300 to work. The evaporator 310 absorbs moisture in the air flow to reduce the humidity in the storage cavity 101, and the vaporization of the moisture absorbs heat to reduce the temperature in the storage cavity 101.

[0167] For another example, in the case that the temperature in the storage cavity 101 is relatively low, the controller 900 can only control the heating assembly 400 to work, and the heating assembly 400 can provide heat to increase the temperature in the storage cavity 101.

[0168] For example, when the humidity inside the storage chamber 101 is low (e.g., less than the second preset humidity), the controller 900 can control only the humidification component 500 to work, and the humidification component 500 can provide humidifying airflow to increase the humidity inside the storage chamber 101.

[0169] In some embodiments, the controller 900 has a third mode in which it controls the fan 250 to operate and controls any two of the heating assembly 400, cooling assembly 300, and humidifying assembly 500 to operate. In this mode, the storage box 10 is suitable for scenarios that require simultaneous adjustment of temperature and humidity, such as scenarios that require heating and humidification or cooling and humidification, to provide more flexible adjustment capabilities.

[0170] Understandably, when the humidity inside the storage chamber 101 is within a preset humidity range but the temperature is high, the evaporator 310, which is part of the refrigeration component 300, absorbs moisture from the airflow to vaporize the moisture and absorb heat, thereby reducing the airflow temperature inside the storage chamber 101. However, the evaporator 310 reduces the humidity of the airflow during the vaporization process. To ensure that the humidity inside the storage chamber 101 remains within the preset humidity range, the refrigeration component 300 and the humidification component 500 can operate simultaneously. In this way, the humidification component 500 can increase the humidity of the airflow, thereby reducing the impact of the evaporator 310 on the humidity of the airflow inside the storage chamber 101.

[0171] Understandably, when the temperature inside the storage chamber 101 is within a preset temperature range but the humidity is high, the evaporator 310, which includes the refrigeration component 300, absorbs moisture from the airflow to vaporize it, thereby reducing the humidity of the airflow inside the storage chamber 101. However, the evaporator 310 absorbs heat when vaporizing moisture. To ensure that the temperature inside the storage chamber 101 remains within the preset temperature range, the refrigeration component 300 and the heating component 400 can operate simultaneously. In this way, the heating component 400 can increase the temperature of the airflow to reduce the impact of the evaporator 310 on the temperature of the airflow inside the storage chamber 101.

[0172] Understandably, when the temperature and humidity inside the storage chamber 101 are low, the heating component 400 and the humidifying component 500 can operate simultaneously. The heating component 400 can provide heat to increase the airflow temperature inside the storage chamber 101, and the humidifying component 500 can provide humidified airflow to increase the airflow humidity inside the storage chamber 101.

[0173] In some embodiments, the controller 900 is configured to switch between a first mode, a second mode, and a third mode. That is, the storage tank 10 can dynamically select a suitable operating mode based on relevant data of the monitored physical parameters of the airflow to ensure the stability and adaptability of the physical parameters of the airflow within the storage environment.

[0174] In some embodiments, the controller 900 further has a fourth mode, in which the controller 900 controls the operation of the air fan 250, and controls the simultaneous operation of the heating assembly 400, the refrigeration assembly 300 and the humidification assembly 500. At this time, the storage box 10 is suitable for complex regulation scenarios requiring simultaneous heating, refrigeration and humidification, to ensure comprehensive regulation of different physical parameters of the air flow.

[0175] In some embodiments, the controller 900 is configured to switch among the first mode, the second mode, the third mode and the fourth mode. That is, the storage box 10 can dynamically select a suitable operating mode according to the relevant data of the monitored physical parameters of the air flow, to ensure the stability and adaptability of the physical parameters of the air flow in the storage environment.

[0176] It should be noted that the refrigeration assembly 300 can have a large load, for example, the load of the refrigeration assembly 300 is greater than or equal to the load threshold. In the case where the refrigeration assembly 300 includes the evaporator 310, the evaporator 310 will excessively consume the heat and moisture of the air flow in the storage cavity 101. At this time, the controller 900 operates in the fourth mode, controls the operation of the heating assembly 400 to supplement the heat of the air flow in the storage cavity 101, and controls the operation of the humidification assembly 500 to supplement the moisture of the air flow in the storage cavity 101, to maintain the constant temperature and humidity of the storage cavity 101.

[0177] In some embodiments, referring to FIG. 13, the air flow circulation assembly 200 further has an air outlet 204, a first air return port 205 and a second air return port 206.

[0178] Referring to FIG. 13, in some embodiments, the air outlet 204 is located at the mixed air passage output port 203b and communicates with the upper part of the storage cavity 101. The mixed air flow in the mixed air passage 203 is discharged through the air outlet 204, to ensure that the mixed air flow can enter the storage cavity 101. It should be noted that the upper part of the storage cavity 101 is the part far away from the ground.

[0179] Referring to FIG. 14, in some embodiments, the first air return port 205 is located at the input port of the first passage 201 and communicates with the lower part of the storage cavity 101. The air flow in the storage cavity 101 passes through the first air return port 205, to ensure that the air flow in the storage cavity 101 can be effectively recycled into the first passage 201. It should be noted that the lower part of the storage cavity 101 is the part close to the ground.

[0180] Referring to FIG. 14, in some embodiments, the second return air inlet 206 is located at the input of the second passage 202 and communicates with the lower portion of the storage cavity 101. The air flow in the storage cavity 101 enters the second passage 202 through the second return air inlet 206, so as to ensure that the air flow in the storage cavity 101 can be effectively recycled into the second passage 202.

[0181] Referring to FIG. 14, in some embodiments, the first return air inlet 205 and the second return air inlet 206 respectively communicate with different positions of the lower portion of the storage cavity 101, so as to ensure that the air flow enters from different positions and thus ensure uniform distribution of the air flow in the storage cavity 101, so as to avoid the situation that the air flow is not smooth in some local positions.

[0182] Referring to FIG. 15, in some embodiments, the air flow circulation assembly 200 further comprises a first plate 210 (such as a decorative plate).

[0183] The air flow circulation assembly 200 further comprises a second plate 220 (such as a front cover), which is located on the side of the first plate 210 away from the storage cavity 101, and at least part of the second passage 202 is formed between the first plate 210 and the second plate 220. That is, the second plate 220 and the first plate 210 can form part of the second passage 202, or can form the entire second passage 202.

[0184] The air flow circulation assembly 200 further comprises a third plate 230 (such as a rear cover), which is located on the side of the second plate 220 away from the storage cavity 101, and the mixing passage 203 is formed between the second plate 220 and the third plate 230.

[0185] The air flow circulation assembly 200 further comprises a fourth plate 240 (such as a back plate), which is located on the side of the third plate 230 away from the storage cavity 101, and the first passage 201 is formed between the third plate 230 and the fourth plate 240.

[0186] In some embodiments, the first plate 210, the second plate 220, the third plate 230 and the fourth plate 240 are sequentially arranged along the thickness direction (for example, the Z direction in FIG. 15) of the cabinet 100.

[0187] It can be understood that the first plate 210, the second plate 220, the third plate 230 and the fourth plate 240 can be sequentially stacked and connected to form the aforementioned first passage 201, second passage 202 and mixing passage 203.

[0188] In some embodiments, the fourth plate 240 and the third plate 230 form a first channel 201 at the middle of the third plate 230. The second plate 220 and the first plate 210 form two second channels 202 at the two side edges of the second plate 220. In addition, the first channel 201 and the two second channels 202 are 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.

[0189] In some embodiments, the middle of the third plate 230 refers to the middle in the length direction (W direction in FIG. 15).

[0190] 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, and then the air flow in the first channel 201 and the two second channels 202 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 the air circulation between the storage cavity 101 and the air circulation assembly 200.

[0191] Referring to FIG. 15, in some embodiments, referring to the foregoing, in the case where the second channel 202 includes the first sub-channel 202A and the second sub-channel 202B. The fourth plate 240 and the third plate 230 form a first channel 201 at the middle of the third plate 230.

[0192] In some embodiments, the first plate 210 and the second plate 220 can cooperate to form the second sub-channel 202B. At this time, the position of the second sub-channel 202B can be selected according to actual conditions. For example, the second sub-channel 202B is located at the lower part of the storage cavity 101. For another example, the second sub-channel 202B is located at the outer side of the storage cavity 101. For another example, the second sub-channel 202B is located at the rear side of the storage cavity 101. Here, the outer side of the storage cavity 101 refers to the outer side of the cabinet 100 that defines it; the rear side of the storage cavity 101 refers to the side that is away from the user when the storage box 10 is in use.

[0193] In some embodiments, the second plate 220 and the first plate 210 form two second sub-channels 202B at the two side edges of the second plate 220. In addition, the first channel 201 and the two second sub-channels 202B are 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.

[0194] 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 sub-channels 202B respectively, and then the air flow in the first channel 201 and the two second sub-channels 202B enters the air mixing channel 203, and finally the air flow in the air mixing channel 203 is output to the storage cavity 101, forming the air flow circulation between the storage cavity 101 and the air flow circulation assembly 200.

[0195] Referring to FIG. 16, in some embodiments, the air flow circulation assembly 200 further comprises a first guide structure 260 located at the communication of the first channel 201, the second channel 202 and the air mixing channel 203, and configured to receive the air flow input by the first channel 201 and the second channel 202 to the air mixing channel 203 and change the flow direction thereof, and output to the storage cavity 101 after mixing in the air mixing channel 203.

[0196] It can be understood that the first guide structure 260 can accept and change the flow direction of one air flow output by the first channel 201 to the air mixing channel 203 and another air flow output by the second channel 202 to the air mixing channel 203, so as to realize the convergence of the two air flows. In the above process, the flow direction of the two air flows is changed, compared with the case where the flow direction is not changed, the contact area between the two air flows is increased, and the mixing degree of the two air flows is improved. In the case where the flow time of the air flow is unchanged, by increasing the mixing degree, the mixing effect of the two air flows can be improved, and thus the precision of air flow mixing can be improved. In the case where the flow speed of the air flow is unchanged, the time required for the mixing degree of the two air flows to meet the demand is reduced, and thus the efficiency of air flow mixing can be improved.

[0197] In some embodiments, referring to FIG. 17, the air flow circulation assembly 200 further comprises a second guide structure 270. The second guide structure 270 is located in the air mixing channel 203. The second guide structure 270 is in communication with the air mixing channel output port 203b and is located downstream of the first guide structure 260. The second guide structure 270 is configured to receive the air flow output by the first guide structure 260 and change the flow direction thereof, and output to the air mixing channel output port 203b after mixing.

[0198] It can be understood that the second guide structure 270 can accept and change the flow direction of the air flow output by the first guide structure 260. In this process, the flow direction of the air flow is changed again, compared with the case where the flow direction is not changed, the contact area of the air flow is increased, and the mixing degree can be further improved.

[0199] In the case that the air flow circulation assembly 200 comprises the first guide structure 260 and the second guide structure 270, the mixing degree of the air flow can be increased, the mixing efficiency and mixing effect of the air flow can be increased, and the error between the physical parameters of the air flow received by the storage cavity 101 and the physical parameters of the target air flow can be reduced, so that the temperature adjustment and humidity adjustment of the air flow with higher precision can be realized, and the storage condition with constant physical parameters of the air flow in the storage box 10 can be formed, thereby facilitating the storage of the articles.

[0200] In some embodiments, the air flow circulation assembly 200 further comprises a third guide structure 280, which is respectively communicated with the mixed air passage output port 203b and the storage cavity 101, and is configured to receive the air flow output by the second guide structure 270 and change the flow direction of the air flow to be output to the storage cavity 101.

[0201] In this way, the mixing degree of the air flow can be increased, the mixing efficiency and mixing effect of the air flow can be increased, and the error between the physical parameters of the air flow received by the storage cavity 101 and the physical parameters of the target air flow can be reduced, so that the temperature adjustment and humidity adjustment of the air flow with higher precision can be realized, and the storage condition with constant physical parameters of the air flow in the storage box 10 can be formed, thereby facilitating the storage of the articles.

[0202] In some embodiments, along the direction of the flow of the air flow in the first passage 201 and the second passage 202, the first guide structure 260 is configured to change the flow direction of the air flow flowing therethrough by a first angle. That is, the direction of the flow of the air flow in the first passage 201 and the second passage 202 is defined as a first initial angle, and the direction of the air flow output by the first passage 201 and the direction of the air flow output by the second passage 202 are changed by the first angle based on the first initial direction, so as to realize the preliminary mixing of the two air flows.

[0203] In some embodiments, along the direction of the flow of the air flow in the first guide structure 260, the second guide structure 270 is configured to change the flow direction of the air flow flowing therethrough by a second angle. That is, the direction of the flow of the air flow in the first guide structure 260 is defined as a second initial angle, and the direction of the air flow output by the first guide structure 260 is changed by the second angle based on the second initial direction, so as to realize the re-mixing of the two air flows.

[0204] In some embodiments, the first angle is smaller than the second angle.

[0205] It can be understood that, in the case that the first angle is equal to the second angle, that is, the airflow flow direction output by the first guide structure 260 is consistent with the airflow flow direction output by the second guide structure 270, the requirement for re-mixing cannot be met; in the case that the first angle is greater than the second angle, that is, after the airflow output by the first guide structure 260 passes through the second guide structure 270, the maximum aperture through which the airflow flows is reduced, although this is conducive to the convergence of the airflow, it cannot substantially change the flow direction of the airflow, and thus cannot perform a higher degree of airflow mixing.

[0206] In some embodiments, the first angle is less than 90°, and the second angle is less than or equal to 90°.

[0207] For example, the first angle can be 1°, 15°, 30°, 45°, 60°, 75°, or 89°, and the second angle can be 1°, 15°, 30°, 45°, 60°, 75°, 89°, or 90°.

[0208] It should be noted that, in the case that the first angle is greater than 90°, the airflow output by the first channel 201 cannot converge with the airflow output by the second channel 202, and thus the mixing effect of the first guide structure 260 cannot be achieved; in the case that the second angle is greater than 90°, the flow direction of the airflow in the second guide structure 270 is opposite to the flow direction of the airflow guided by the first guide structure 201, and thus the mixing effect of the second guide structure 270 cannot be achieved.

[0209] In some embodiments, the first angle is less than or equal to 45°, and the second angle is greater than or equal to 45° and less than or equal to 90°.

[0210] In this way, the directions of the two airflows can be changed, the stagnation or disorder of the two airflows in the first guide structure 260 can be avoided, good flowability can be maintained, and the airflows can be mixed multiple times on the basis of preliminary mixing to ensure the uniformity and stability of the airflows.

[0211] Referring to FIG. 16, in some embodiments, the first guide structure 260 is formed with a mixing guide channel 261, which is connected to the upstream of the air mixing channel 203 to ensure that the airflows can be effectively mixed.

[0212] The first guide structure 260 is further formed with a first guide channel 262, which includes an input port and an output port, and the input port and the output port of the first guide channel 262 are respectively connected to the downstream of the first channel 201 and the upstream of the mixing guide channel 261 to guide the airflows of the first channel 201 into the mixing guide channel 261.

[0213] The first guide structure 260 further forms a second guide passage 263, which includes an input port and an output port, and the input port and the output port of the second guide passage 263 are respectively communicated with the downstream of the second passage 202 and the upstream of the mixed guide passage 261, so as to guide the airflow in the second passage 202 to enter the mixed guide passage 261.

[0214] In some embodiments, the airflow in the first passage 201 and the airflow in the second passage 202 are unidirectional to the mixing passage 203. That is, the airflow in the first guide passage 262 cannot enter the second guide passage 263, and the airflow in the second guide passage 263 cannot enter the first guide passage 262.

[0215] Referring to FIG. 16, in some embodiments, the flow rate of the airflow received by the mixed guide passage 261 is less than the flow rate of the airflow output by the first guide passage 262 and the flow rate of the airflow output by the second guide passage 263, that is, the flow rate of the airflow received by the mixed guide passage 261 is less than any one of the flow rate of the airflow output by the first guide passage 262 and the flow rate of the airflow output by the second guide passage 263.

[0216] In this way, the airflow is contracted downstream of the first guide passage 262 and the second guide passage 263, the flow rate of the airflow is increased, and the pressure is reduced, forming a Venturi effect, thereby forming the unidirectional flow of the airflow in the first guide passage 262 and the second guide passage 263.

[0217] Referring to FIG. 17, in some embodiments of the present disclosure, the first guide structure 260 includes a first guide plate 264.

[0218] The first guide structure 260 further includes a second guide plate 265, and the second guide plate 265 cooperates with the first guide plate 264 to form the mixed guide passage 261.

[0219] The first guide structure 260 further includes 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. The first guide passage 262 is formed between the first guide plate 264 and the third guide plate 266, and the second guide passage 263 is formed between the second guide plate 265 and the third guide plate 266.

[0220] In this way, the first guide structure 260 can form the first guide passage 262 communicated with the first passage 201, the second guide passage 263 communicated with the second passage 202, and the mixed guide passage 261 communicated with the input port 203a of the mixing passage, thereby realizing the flow-converging function and the preliminary mixing function of the first guide structure 260.

[0221] In some embodiments, the length of the first guide plate 264, the length of the second guide plate 265, and the length of the third guide plate 266 are all greater than the length of the first guide plate 264 in the flow direction of the airflow in the air mixing channel 203.

[0222] In this way, the time and space for the airflow in the first channel 201 to be preliminarily mixed before entering the mixing guide channel 261 can be increased, and the resistance of the airflow can be reduced, ensuring that the airflow can smoothly enter the mixing guide channel 261 to improve the mixing efficiency.

[0223] It can be understood that, in order to form the first guide channel 262 and the second guide channel 263 described above, the first guide plate 264, the second guide plate 265, and the third guide plate 266 can all be arc-shaped plates.

[0224] For example, referring to FIG. 17, the middle portions of the first guide plate 264 and the second guide plate 265 are convex in the direction towards the third guide plate 266, and the third guide plate 266 is convex in the direction towards the second guide plate 265. It should be noted that the convex positions of the first guide plate 264, the second guide plate 265, and the third guide plate 266 are the downstream of the first guide channel 262 and the output of the second guide channel 263, that is, the input of the mixing guide channel 261. Here, the middle portions of the first guide plate 264 and the second guide plate 265 refer to the middle portions in the flow direction of the airflow in the air mixing channel 203.

[0225] In this way, the contact area of the airflow can be increased, the resistance and vortex can be reduced, and the mixing efficiency can be improved.

[0226] In some embodiments, referring to FIG. 17, the convex position of the third guide plate 266 is provided with an inlet 267, the inlet 267 is configured to communicate the mixing guide channel 261, the first guide channel 262, and the second guide channel 263, and is configured to realize a three-way connection. Here, the three-way connection refers to the mutual communication between the mixing guide channel 261, the first guide channel 262, and the second guide channel 263. In this way, the mixing can be performed in the initial stage of the convergence of the two airflows, and the mixing efficiency can be improved.

[0227] It can be understood that, in order to ensure the communication performance between the multiple guide channels, the angle between the flow direction of the airflow at the output of the first guide channel 262 and the flow direction of the airflow at the output of the mixing guide channel 261 can be the same as the angle between the flow direction of the airflow at the output of the second guide channel 262 and the flow direction of the airflow at the output of the mixing guide channel 261.

[0228] In some embodiments, the aforementioned first angle refers to the angle between the flow direction of the airflow at the output of the first guide channel 262 and the flow direction of the airflow at the output of the mixing guide channel 261, or refers to the angle between the flow direction of the airflow at the output of the second guide channel 262 and the flow direction of the airflow at the output of the mixing guide channel 261.

[0229] In some embodiments, the second guide structure 270 is formed with a first deflection channel 271, the first deflection channel 271 is located close to the mixing channel input 203a, and the flow direction of the airflow in the first deflection channel 271 is different from the flow direction of the airflow in the mixing channel 203.

[0230] By changing the flow direction of the airflow, the disturbance and mixing effect of the airflow are increased, the uniformity and stability of the airflow are ensured, and the uniformity of the storage environment inside the storage box 10 is improved.

[0231] Referring to FIG. 18, in some embodiments, the second guide structure 270 includes at least one first deflection plate 273. The at least one first deflection plate 273 is located at the output of the first guide structure 260. In the case where the at least one first deflection plate 273 includes a plurality of first deflection plates 273, the plurality of first deflection plates 273 are arranged in the mixing channel 203 in a spaced manner along a direction perpendicular to the flow direction of the airflow in the mixing channel 203, and a first deflection channel 271 is formed between any two adjacent first deflection plates 273 in the plurality of first deflection plates 273; the surface extension direction (such as the first direction A) of the first deflection plate 273 intersects with the flow direction of the airflow in the mixing channel 203.

[0232] For example, the airflow flowing through the first deflection channel 271 flows in the first direction A, the flow direction of the airflow in the mixing channel 203 is the second direction B, and the first direction A intersects with the second direction B, so that the airflow flowing in the first direction A and the airflow flowing in the second direction B can be mixed, the disturbance and mixing effect of the airflow are increased, and the uniformity and stability of the airflow are ensured, thereby improving the uniformity of the storage environment inside the storage box 10.

[0233] In some embodiments, the angle between the flow direction of the airflow in the first deflection channel 271 and the flow direction of the airflow in the mixing channel 203 is an acute angle, i.e., the angle between the first direction A and the second direction B is an acute angle.

[0234] Referring to FIG. 18, in some embodiments, the flow direction of the airflow in the first deflection passage 271 is perpendicular to the flow direction of the airflow in the air mixing passage 203, i.e., 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 deflection passage 271 and the airflow not passing through the first deflection passage 271 is large, so that the mixing degree between the airflow passing through the first deflection passage 271 and the airflow not passing through the first deflection passage 271 is high, which can improve the mixing effect of the air mixing passage 203 on the two airflows.

[0235] It should be noted that in the case where the angle between the first direction A and the second direction B is an obtuse angle, the first direction A is opposite to the second direction B, at this time, the resistance between the flow direction of the airflow in the first deflection passage 271 and the flow direction of the airflow in the air mixing passage 203 is large, which further affects the flow of the airflow in the air mixing passage 203.

[0236] Referring to FIG. 19, in some embodiments, the second guide structure 270 is formed with a plurality of first deflection passages 271, and the flow directions of the airflows in the plurality of first deflection passages 271 are different. That is, the airflow directions in each of the first deflection passages 271 are different.

[0237] In this way, the airflows between two adjacent first deflection passages 271 can also be mixed to improve the disturbance effect and mixing effect of the airflow.

[0238] Referring to FIG. 18, in some embodiments, the second guide structure 270 is formed with a plurality of first deflection passages 271, and the flow directions of the airflows in the plurality of first deflection passages 271 are the same. That is, the airflow directions in each of the first deflection passages 271 are the same, so that the flow path of the airflow output by the second guide structure 270 is consistent, and the uniformity and stability of the airflow are improved.

[0239] In some embodiments, the first deflection plate 273 is configured to flow the airflow in the first deflection passage 271 and change the Reynolds number of the airflow until the flow state of the airflow becomes turbulent.

[0240] It can be understood that in the case where the flow state of the airflow is turbulent, it indicates that one airflow output by the first passage 201 and one airflow output by the second passage 202 flow in a random and chaotic manner, and the two airflows are strongly mixed, so that the mixing degree of the airflow can be enhanced in the second guide structure 270, and the uniformity and stability of the airflow are ensured to improve the uniformity of the storage environment inside the storage box 10.

[0241] In some embodiments, the function relationship of the Reynolds number required for the flow state of the gas flow to be turbulent is shown in equation (1). Re = p v L0 / m (1)

[0242] wherein Re is the Reynolds number required for the flow state of the gas flow to be turbulent, p is the density of the gas flow, v is the flow velocity of the gas flow, L0is the characteristic length required for the flow state of the gas flow to be turbulent, and m is the dynamic viscosity of the gas flow.

[0243] According to the above, when the density, flow velocity, and dynamic viscosity of the gas flow are constant, the Reynolds number is proportional to the characteristic length. Therefore, by adjusting the characteristic length, the Reynolds number of the gas flow can be changed.

[0244] It can be understood that when the Reynolds number of the gas flow is low (for example, less than 2000), the flow state of the gas flow is usually laminar. Therefore, in order to change the flow state of the gas flow in the first turning channel 271 to be turbulent, the Reynolds number of the gas flow needs to be increased.

[0245] For example, when the Reynolds number Re of the gas flow reaches (for example, is equal to) 2300, the turbulent flow of the gas flow can be effectively induced. In this embodiment, it is assumed that v = 6 m / s, m = 0.0000179 Pa.s, and p = 1.29. At this time, according to equation (1), L0= 5.3 mm. That is, when the extension length of the first turning plate 273 is 5.3 mm, the turbulent flow of the gas flow can be induced, and the mixing degree of the gas flow is increased.

[0246] It should be noted that the above data is only an example, which can be adjusted according to actual conditions.

[0247] In some embodiments, the actual extension length of the first turning plate 273 is L, and the relationship between L and L0is: 0.4L0

[0248] It can be understood that when the proportional relationship between L and L0is within the preset proportional range, the change of the flow state of the gas flow in the first turning channel 271 can be facilitated.

[0249] When the first turning plate 273 is in the above proportion, the first turning plate 273 can effectively change the flow state of the gas flow, so that the flow state of the gas flow is turbulent, and the mixing degree of the gas flow is increased. When L is less than the minimum value in the above proportional range, it indicates that the first turning plate 273 is short, and the Reynolds number of the gas flow cannot be increased, and the turbulent flow cannot be induced. When L is greater than the maximum value in the above proportional range, it indicates that the first turning plate 273 is long, and the flow resistance of the gas flow is increased, which affects the flow of the gas flow in the first turning channel 271.

[0250] In some embodiments, the relationship between L and L0 is: 0.5L0≤L≤1.5L0. At this time, L0 can be an integer. On this basis, L can take a value of half of L0, at which time, the turbulent flow can be achieved, and the processing of the first deflection plate 273 is facilitated, and the production precision and assembly precision of the first deflection plate 273 are reduced.

[0251] In some embodiments, the first deflection plate 273 can be a plate body or a column body. In other embodiments, the end face of the first deflection plate 273 can be circular, rectangular, or round rectangular.

[0252] It can be understood that at this time, the aforementioned second angle can refer to the included angle between the flow direction of the gas in the first deflection channel 273 (i.e., the first direction A) and the flow direction of the gas in the air mixing channel 203 (i.e., the second direction B).

[0253] Referring to FIG. 18, in some embodiments, when the surface extension directions of the plurality of first deflection plates 273 are all the same, the flow directions of the gas in the plurality of first deflection channels 271 are all the same, so that the second guide structure 270 can output airflow with consistent flow paths, and the uniformity and stability of the airflow are improved.

[0254] Referring to FIG. 20, in some embodiments, along the surface extension direction of the first deflection plate 273, the length of the first deflection plate 273 is L, and the distance between the adjacent two first deflection plates 273 is S1, and the relationship between L and S1 is: L<S1<5L.

[0255] It can be understood that the distance S1 can affect the size of the flow space of the airflow between the adjacent two first deflection plates 273.

[0256] The distance S1 satisfying the above ratio relationship is helpful for the airflow to be fully mixed between the adjacent two first deflection plates 273, so as to improve the mixing efficiency.

[0257] It should be noted that in the case where S1 is less than the minimum value in the above ratio range, it indicates that the distance between the adjacent two first deflection plates 273 is too small, which can cause the airflow to fail to smoothly enter the first deflection channel 271, thereby affecting the flow of the airflow. In the case where S1 is greater than the maximum value in the above ratio range, it indicates that the distance between the adjacent two first deflection plates 273 is too large, and the flow rate of the airflow flowing into the first deflection channel 271 is low (e.g., less than a preset flow rate), thereby affecting the Reynolds number of the airflow, so that the change of the flow state of the airflow cannot be achieved.

[0258] Referring to FIG. 20, in some embodiments, the relationship between L and S1 is: 2L≤S1≤4L.

[0259] It should be noted that, in the case that the value of S1 is in the range of [L, 2L], although the flow state of the airflow can be changed, the flow path of the airflow is relatively short, and the situation that only part of the airflow changes its flow state can occur; in the case that the value of S1 is in the range of [4L, 5L], although the length of the flow path of the airflow can ensure that the flow state of the entire airflow changes, the situation that the airflow cannot smoothly enter the second turning channel 272 can occur.

[0260] In some embodiments, the second guide structure 270 is further formed with a second turning channel 272, the second turning channel 272 is located downstream of the first turning channel 271, and the flow direction of the airflow in the second turning channel 272 is the same as the flow direction of the airflow in the air mixing channel 203, that is, the airflow passing through the second turning channel 272 also flows in the second direction B.

[0261] In this way, in the case that the first turning channel 271 outputs the airflow to the second turning channel 272, the second turning channel 272 can change the flow direction of the airflow output by the first turning channel 271 and make the airflow mix again; and the second turning channel 272 can provide a guiding effect for the airflow to improve the uniformity of the airflow flow, so as to ensure that the air mixing channel 203 can output airflow with high mixing degree and high uniformity.

[0262] Referring to FIG. 20, in some embodiments, the second guide structure 200 further includes at least one second turning plate 274, and the at least one second turning plate 274 is located at the output port of the first turning plate 273. In the case that the at least one second turning plate 274 includes a plurality of second turning plates 274, the plurality of second turning plates 274 are arranged in the air mixing channel 203 in a spaced manner along a direction perpendicular to the flow direction of the airflow in the air mixing channel 203, and a second turning channel 272 is formed between adjacent two second turning plates 274; the surface of the second turning plate 274 extends in the same direction as the flow direction of the airflow in the air mixing channel 203.

[0263] In some embodiments, the second turning plate 274 is configured to make the airflow flow in the second turning channel 272 and change the Reynolds number of the airflow until the flow state of the airflow changes from turbulent flow to laminar flow.

[0264] It can be understood 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 flow. Therefore, in order to make the airflow in the second turning channel 272 change to the laminar flow state, it is necessary to reduce the Reynolds number of the airflow after the airflow flows out of the first turning channel 271.

[0265] It can be understood that, in the case that the flow state of the air flow is laminar, i.e., the second turning channel 274 receives the air flow output by the first turning channel 273 and enables the air flow to flow along mutually parallel paths, the flow consistency of the air flow in the mixing channel 203 can be improved, and thus the uniformity and stability of the air flow output can be ensured, so as to improve the uniformity of the storage environment in the storage box 10.

[0266] In some embodiments, the extension length of the second turning plate 274 is less than the extension length of the first turning plate 273, i.e., the Reynolds number of the air flow can be effectively reduced.

[0267] In some other embodiments, no structure is arranged between the second turning plate 274 and the first turning plate 273, i.e., the air flow enters the mixing channel 203 after passing through the first turning channel 271. Since the maximum hole diameter of the mixing channel 203 through which the air flow passes is greater than the maximum hole diameter of the first turning channel 271, the density of the air flow is reduced, and the Reynolds number of the air flow can be reduced. The shape of the through hole of the mixing channel 203 through which the air flow passes is not limited in some embodiments of the present disclosure.

[0268] In some embodiments, in the case that the shape of the through hole of the mixing channel 203 through which the air flow passes is circular, the maximum hole diameter through which the air flow passes is the diameter of the circle; in the case that the shape of the through hole of the mixing channel 203 through which the air flow passes is triangular, the maximum hole diameter through which the air flow passes is the length of the maximum side length of the triangle; and in the case that the shape of the through hole of the mixing channel 203 through which the air flow passes is rectangular, the maximum hole diameter through which the air flow passes is the length of the diagonal of the rectangle.

[0269] Referring to FIG. 20, in some embodiments, when the surface extension direction of the first turning plate 273 is perpendicular to the flow direction of the air flow in the mixing channel 203, the minimum distance between the adjacent first turning plate 273 and the second turning plate 274 along the flow direction of the air flow in the mixing channel 203 is S2, and the relationship between L and S2 is: L < S2 < 6L.

[0270] It can be understood that the distance S2 can affect the size of the flow space between the first turning plate 273 and the second turning plate 274.

[0271] The distance S2 satisfying the above ratio relationship is helpful for the air flow to change the flow state between the adjacent first turning plate 273 and the second turning plate 274.

[0272] It should be noted that, in the case that S2 is less than the minimum value in the above-mentioned proportion range, it indicates that the distance between the adjacent first deflection plate 273 and the second deflection plate 274 is too small, which cannot effectively change the flow state of the air flow, and thus cannot realize the output of the laminar air flow; in the case that S2 is greater than the maximum value in the above-mentioned proportion range, it indicates that the distance between the adjacent first deflection plate 273 and the second deflection plate 274 is too large, which can cause the air flow to fail to smoothly enter the second deflection passage 272, and thus affect the flow of the air flow.

[0273] In some embodiments, the relationship between L and S2 is: 2L≤S2≤5L.

[0274] It should be noted that, in the case that the value of S2 is in the range of [L, 2L], although the flow state of the air flow can be changed, the flow path of the air flow is relatively short, and the situation that only part of the air flow changes its flow state can occur; in the case that the value of S1 is in the range of [5L, 6L], although the length of the flow path of the air flow can ensure that the flow state of all the air flow changes, the situation that the air flow fails to smoothly enter the second deflection passage 272 can occur.

[0275] It can be understood that, in the case that the air flow circulation assembly 200 includes the first guide structure 260 and the second guide structure 270, the air flow flow process is as follows: the air flow in the storage cavity 101 enters the first passage 201 through the input port of the first passage 201 and the air flow in the storage cavity 101 enters the second passage 202 through the input port of the second passage 202 under the influence of the fan 250. The air flow in the first passage 201 enters the mixed guide passage 261 through the first guide passage 262, and at the same time, the air flow in the second passage 202 enters the mixed guide passage 261 through the second guide passage 263. After the first guide structure 260 changes the flow directions of the two air flows respectively, the two air flows are preliminarily mixed and output to the air mixing passage input port 203a. The air flow flows through the first deflection passage 271 in the air mixing passage 203, the flow direction of the air flow changes, and the air flow is mixed again. Then, the air flow passes through the second deflection passage 272, or passes through the air mixing passage with a shorter length and then passes through the second deflection passage 272, and the second deflection passage 272 is configured to guide the air flow to the air mixing passage output port 203b. Finally, the air flow enters the storage cavity 101 through the air mixing passage output port 203b to form air flow circulation.

[0276] Referring to FIG. 18, in some embodiments, the air flow circulation assembly 200 further comprises a third guide structure 280, which comprises an input port and an output port, and is in communication with the mixed air passage output port 203b through the input port and with the storage cavity 101 through the output port. The output port of the third guide structure 280 has a larger aperture than the mixed air passage output port 203b. In this way, the air flow has a larger aperture when flowing through the third guide structure 280, and the flow rate of the air flow is reduced, achieving soft air outlet and ensuring that the air flow circulation in the storage cavity 101 is relatively stable and uniform.

[0277] Referring to FIG. 18, in some embodiments, the third guide structure 280 is formed with a first guide-out passage 281, which comprises an output port. The output port of the first guide-out passage 281 is in communication with the mixed air passage output port 203b, and the output port of the first guide-out passage 281 has a larger aperture than the mixed air passage output port 203b. In this way, the flow rate of the air flow is reduced, achieving soft air outlet and ensuring that the air flow circulation in the storage cavity 101 is relatively stable and uniform.

[0278] In some embodiments, the third guide structure 280 is further formed with a second guide-out passage 282, which comprises an output port. The output port of the second guide-out passage 282 is in communication with the mixed air passage output port 203b, and the output port of the second guide-out passage 282 has a larger aperture than the mixed air passage output port 203b. In this way, the flow rate of the air flow is reduced, achieving soft air outlet and ensuring that the air flow circulation in the storage cavity 101 is relatively stable and uniform.

[0279] In some embodiments, the output port of the first guide-out passage 281 has a different aperture from the output port of the second guide-out passage 282. For example, the output port of the first guide-out passage 281 has a larger aperture than the output port of the second guide-out passage 282; or for another example, the output port of the first guide-out passage 281 has a smaller aperture than the output port of the second guide-out passage 282.

[0280] Some embodiments of the present disclosure do not limit the shape of the output port of the first guide-out passage 281, the output port of the second guide-out passage 282, the output port of the third guide structure 280, and the mixed air passage output port 203b.

[0281] In some embodiments, when the output port of the first export channel 281, the output port of the second export channel 282, the output port of the third guide structure 280 and the output port of the air mixing channel 203 are circular in shape, the diameter of the air flow aperture is circular; when the output port of the first export channel 281, the output port of the second export channel 282, the output port of the third guide structure 280 and the output port of the air mixing channel 203 are triangular in shape, the maximum length of the air flow aperture is the maximum side length of the triangle; when the output port of the first export channel 281, the output port of the second export channel 282, the output port of the third guide structure 280 and the output port of the air mixing channel 203 are rectangular in shape, the maximum length of the air flow aperture is the diagonal of the rectangle.

[0282] It can be understood that a larger output port aperture can achieve a greater degree of soft air outlet, and a smaller output port aperture can achieve a smaller degree of soft air outlet. The storage box 10 can adjust the positions of the first export channel 281 and the second export channel 282 according to the needs of the stored items to match items with different needs, thereby achieving adaptive soft air outlet.

[0283] In some embodiments, the ratio between the aperture of the output port of the first export channel 281 and the aperture of the output port of the air mixing channel 203 is greater than or equal to 3. At this time, the air flow rate is reduced when output to the storage cavity 101, achieving soft air outlet, ensuring that the air flow circulation in the storage cavity 101 is relatively stable and uniform, and can reduce direct impact on the stored items, protecting the integrity of the stored items.

[0284] In some embodiments, the ratio between the aperture of the output port of the second export channel 282 and the aperture of the output port of the air mixing channel 203b is greater than or equal to 3.

[0285] At this time, the air flow rate is reduced when output to the storage cavity 101, achieving soft air outlet, ensuring that the air flow circulation in the storage cavity 101 is relatively stable and uniform, and can reduce direct impact on the stored items, protecting the integrity of the stored items.

[0286] It can be understood that when the ratio between the aperture of the output port of the first export channel 281 and the aperture of the output port of the air mixing channel 203 or the ratio between the aperture of the output port of the second export channel 282 and the aperture of the output port of the air mixing channel 203b is too small (e.g., less than 3), the aperture of the output port of the air mixing channel 203b cannot be effectively increased, the air outlet amount of the air flow circulation assembly 200 cannot meet the standard of soft air outlet, and thus the air flow circulation assembly 200 cannot effectively achieve soft air outlet.

[0287] Referring to FIG. 15, in some embodiments, the first export channel 281 and the second export channel 282 can be located at different positions within the storage cavity 101. For example, the first export channel 281 can be located above the second export channel 282; for another example, the first export channel 281 can be located below the second export channel 282. It should be noted that the lower channel is closer to the articles within the storage cavity 101 than the upper channel.

[0288] Here, the first export channel 281 being located above the second export channel 282 means that the first export channel 281 is located on the side of the second export channel 282 away from the second guide structure 270; the first export channel 281 being located below the second export channel 282 means that the first export channel 281 is located on the side of the second export channel 282 close to the second guide structure 270.

[0289] In some embodiments, the first export channel 281 has an output aperture with a larger aperture than the output aperture of the second export channel 282, and the first export channel 281 is located below the second export channel 282.

[0290] In this way, the first export channel 281 is closer to the articles within the storage cavity 101 than the second export channel 282, and has a larger output aperture, which can ensure that the airflow is significantly reduced in flow rate when output, to achieve soft air output, and ensure that the airflow circulation within the storage cavity 101 is stable and uniform.

[0291] In some embodiments, the ratio between the aperture of the output aperture of the first export channel 281 and the aperture of the output aperture of the second export channel 282 is in the range of (1, 3].

[0292] In this way, the flow path of the airflow between the export channels can meet the requirements, increasing the contact area between the airflows and improving the mixing efficiency; and the airflow can achieve soft air output after flowing through the first export channel 281, ensuring the stability and uniformity of the airflow circulation within the storage cavity 101.

[0293] It can be understood that when the ratio between the aperture of the output aperture of the first export channel 281 and the aperture of the output aperture of the second export channel 282 is less than 1, the aperture of the output aperture of the first export channel 281 is less than or equal to the aperture of the output aperture of the second export channel 282, the air output of the second export channel 282 is softer, but the distance between the airflow and the articles within the storage cavity 101 is increased, reducing the storage effect on the articles; when the aforementioned ratio is greater than 3, the aperture of the output aperture of the first export channel 281 is too large, which can cause the airflow flow rate of the second export channel 282 to be too high, causing the airflow to directly enter the storage cavity 101 without passing through the first export channel 281, reducing the soft air output effect.

[0294] In some embodiments, the ratio between the aperture of the output of the first outlet channel 281 and the aperture of the output of the second outlet channel 282 is 7:3.

[0295] In this way, the flow path of the air flow between the outlet channels can meet the requirements, increasing the contact area between the air flows and improving the mixing efficiency; and the air flow can be ensured to be soft after flowing through the first outlet channel 281, ensuring the stability and uniformity of the air flow circulation in the storage cavity 101.

[0296] It can be understood that in the case where the ratio between the aperture of the output of the first outlet channel 281 and the aperture of the output of the second outlet channel 282 is less than 7 / 3, the proportion of the aperture of the output of the first outlet channel 281 is small, and the air flow of the second outlet channel 282 is relatively soft, but the distance between the air flow and the articles in the storage cavity 101 is increased, reducing the storage effect on the articles; in the case where the ratio is greater than 7 / 3, the aperture of the output of the first outlet channel 281 is too large, which can cause the air flow of the second outlet channel 282 to be too high, resulting in that the air flow does not pass through the first outlet channel 281 but directly enters the storage cavity 101, reducing the effect of soft air flow.

[0297] In other embodiments, the aperture of the output of the second outlet channel 282 is greater than the aperture of the output of the first outlet channel 281, and the second outlet channel 282 is located below the first outlet channel 281. The beneficial effects and the proportional relationship between the aperture of the output of the second outlet channel 282 and the aperture of the output of the first outlet channel 281 can be referred to the related content when the aperture of the output of the first outlet channel 281 is greater than the aperture of the output of the second outlet channel 282, and the first outlet channel 281 is located below the second outlet channel 282, which will not be described here.

[0298] Referring to FIG. 21, in some embodiments, the first plate 210 has the aforementioned air outlet 204, which is located at the upper portion of the first plate 210, is communicated with the mixed air outlet 203b, and is communicated with the upper portion of the storage cavity 101. The air outlet 204 is configured to discharge the mixed air flow, ensuring that the mixed air flow can enter the storage cavity 101. The upper air outlet helps to uniformly distribute the air flow in the storage cavity 101, avoiding local air flow. The first plate 210 also has a first air return port 205, which is located at the lower portion of the first plate 210, is communicated with the input port of the first channel 201, and is communicated with the lower portion of the storage cavity 101. The first air return port 205 is configured to receive the air flow in the storage cavity 101, ensuring that the air flow in the storage cavity 101 can be effectively recycled into the first channel 201.

[0299] The first plate 210 also has a second return air opening 206 located at a lower portion of the first plate 210, which is in communication with the input of the second channel 202 and the lower portion of the storage cavity 101. The second return air opening 206 is configured to receive the air flow in the storage cavity 101, ensuring that the air flow in the storage cavity 101 can be effectively recycled into the second channel.

[0300] The first return air opening 205 and the second return air opening 206 are respectively in communication with different positions of the lower portion of the storage cavity 101.

[0301] By providing multiple return air openings at different positions and ensuring that the air flow enters from different positions, uniform distribution of the air flow in the storage cavity 101 can be ensured to avoid local air flow stagnation in the storage cavity 101.

[0302] The second return air opening 206 is located close to the centerline of the storage cavity 101, which helps to concentrate the return air and improve the efficiency of air flow recycling.

[0303] In some embodiments, the first plate 210 has multiple first return air openings 205, which are all located outside the second return air opening 206. Here, the outside of the second return air opening 206 refers to the two sides of the second return air opening 206 away from the centerline of the storage cavity 101.

[0304] The multiple first return air openings 205 help to ensure uniform recycling of the air flow in the storage cavity 101 and avoid local air flow stagnation in the storage cavity 101. Moreover, the first return air openings 205 are located outside the second return air opening 206, which helps to recycle the peripheral air flow of the storage cavity 101.

[0305] In other embodiments, the first return air opening 205 is located close to the centerline of the storage cavity 101, which helps to concentrate the return air and improve the efficiency of air flow recycling.

[0306] In other embodiments, the first plate 210 has multiple second return air openings 206, which are all located outside the first return air opening 205. Here, the outside of the first return air opening 205 refers to the two sides of the first return air opening 205 away from the centerline of the storage cavity 101.

[0307] The multiple second return air openings 206 help to ensure uniform recycling of the air flow in the storage cavity 101 and avoid local air flow stagnation in the storage cavity 101. Moreover, the second return air openings 206 are located outside the first return air opening 205, which helps to recycle the peripheral air flow of the storage cavity 101.

[0308] The design of the air return openings (such as the first air return openings 205 or the second air return openings 206) on the outer side of the storage cavity 101 and the air return openings (such as the second air return openings 206 or the first air return openings 205) at the midline position in some embodiments of the present disclosure helps to achieve stratified recovery of the air flow in the storage cavity 101, improve the circulation efficiency of the air flow, and ensure the uniformity and stability of the air flow circulation in the storage cavity 101.

[0309] Referring to FIG. 15, in some embodiments, the air outlet 204 includes a first air outlet 207 which is communicated with the first guide-out channel 281 in the case where the third guide structure 280 is arranged in the air mixing channel 203.

[0310] The air outlet 204 further includes a second air outlet 208 which is communicated with the second guide-out channel 282.

[0311] In some embodiments, the aperture of the output port of the first air outlet 207 is the same as the aperture of the output port of the second air outlet 208. In this way, the flow resistance of the air flow at the two air outlets (such as the first air outlet 207 and the second air outlet 208) can be ensured to be the same, the flow rate difference of the air flow at the two air outlets can be avoided, and the flow amount of the air flow at the two air outlets can be ensured to be the same, so as to improve the uniformity and stability of the air flow adjustment.

[0312] The present disclosure does not limit the shape of the output port of the first air outlet 207 and the output port of the second air outlet 208 in some embodiments.

[0313] In some embodiments, in the case where the shape of the output port of the first air outlet 207 and the output port of the second air outlet 208 is circular, the diameter of the circular air flow aperture can be used; in the case where the shape of the output port of the first air outlet 207 and the output port of the second air outlet 208 is triangular, the length of the maximum side of the triangular air flow aperture can be used; and in the case where the shape of the output port of the first air outlet 207 and the output port of the second air outlet 208 is rectangular, the length of the diagonal of the rectangular air flow aperture can be used.

[0314] Referring to FIG. 22, in some embodiments, the side of the second plate 220 away from the storage cavity 101 forms the first channel 201, i.e., the first channel 201 is formed between the second plate 220 and the third plate 230. The side of the second plate 220 close to the storage cavity 101 forms the second channel 202, i.e., the second channel 202 is formed between the second plate 220 and the first plate 210.

[0315] At this time, the air flow is as follows: the air flow in the storage cavity 101 is divided into two under the influence of the fan 250, the first one enters the first channel 201, and the refrigeration assembly 300 cools the air flow passing through the first channel 201; the second one enters the second channel 202, and the humidification assembly 500 humidifies the air flow passing through the second channel 202. The cooled first air flow and the humidified second air flow enter the air mixing channel 203 through the air mixing channel input port 203a. Then, the cooled air flow and the humidified air flow are mixed in the air mixing channel 203 and then enter the storage cavity 101 through the air mixing channel output port 203b, forming an air flow circulation.

[0316] From the above, it can be seen that the humidification assembly 500 cannot receive the cooled air flow, and thus cannot affect the humidity of the air flow entering the storage cavity 101. In this way, the humidity adjustment accuracy of the storage box 10 can be improved, which is beneficial to the storage of the goods.

[0317] Referring to FIG. 22, in some embodiments, along the surface extension direction of the second plate 220, the input port of the first channel 201 and the input port of the second channel 202 are arranged at intervals. In this way, it is helpful to avoid the direct mixing of the air flows in the two channels (such as the first channel 201 and the second channel 202), and to ensure that the cooling and humidification processes are carried out independently. In this way, it can prevent the humidified air flow from being cooled and dehumidified again by the refrigeration assembly 300 before entering the storage cavity 101, thereby improving the accuracy of the humidity adjustment of the air flow.

[0318] Referring to FIG. 6, in some embodiments, the number of second channels 202 is two, that is, two second channels 202 are jointly defined between the first plate 210 and the second plate 220, and correspondingly, the number of humidification assemblies 500 is increased to 2. By increasing the number of second channels 202 and the number of humidification assemblies 500, the humidification capacity of the humidification assembly 500 can be improved, so that the humidity in the storage cavity 101 can be adjusted more quickly.

[0319] Along the surface extension direction of the second plate 220, the input ports of the two second channels 202 are respectively located on the opposite sides of the lower part of the second plate 220. The input port of the first channel 201 is located at the middle position of the lower part of the second plate 220.

[0320] In this way, the air flow can enter the first channel 201 from the middle position of the storage cavity 101 to separate from the two second channels 202 distributed on both sides of the storage cavity 101, which can avoid the humidified air flow from flowing back into the second channel 202, and further avoid the refrigeration assembly 300 from receiving the humidified air flow.

[0321] Referring to FIG. 21, in some embodiments, the fan 250 includes a plurality of second fans 252, for example, the fan 250 includes two second fans 252.

[0322] The second fan 252 is arranged in the second channel 202 and configured to drive the air flow in the second channel 202 to the mixing channel 203. In this way, the second fan 252 can work simultaneously to increase the air flow speed in the second channel 202, thereby increasing the air flow circulation speed between the storage cavity 101 and the air flow circulation assembly 200.

[0323] In some embodiments, the second fan 252 is an axial fan, the axis of the axial fan is perpendicular to the surface of the second plate 220, and the input port of the axial fan faces the storage cavity 101.

[0324] Referring to FIG. 23, in some embodiments, the third plate 230 forms the first channel 201 on the side away from the storage cavity 101, and the third plate 230 separates the storage cavity 101 and the first channel 201.

[0325] At this time, the air flow process is as follows: the air flow in the storage cavity 101 enters the first channel 201 under the action of the fan 250, and the refrigeration assembly 300 cools the air flow passing through the first channel 201. Then, the cooled air flow enters the mixing channel 203 through the mixing channel input port 203a. Then, after mixing with the air flow output by the second channel 202 in the mixing channel 203, it enters the storage cavity 101 through the mixing channel output port 203b to form air flow circulation.

[0326] It can be understood that in the above air flow process, although the storage cavity 101 is in communication with the first channel 201, the third plate 230 can separate the storage cavity 101 and the refrigeration assembly 300, so as to increase the direct distance between the refrigeration assembly 300 and the storage cavity 101, and the air flow enters the mixing channel 203 through the first channel 201 and cannot backflow. Therefore, the third plate 230 can reduce the direct influence of the refrigeration assembly 300 on the inside of the storage cavity 101, thereby avoiding the influence of the refrigeration assembly 300 on the temperature uniformity of the storage cavity 101, which is conducive to the storage of goods.

[0327] Here, the direct distance between the refrigeration assembly 300 and the storage cavity 101 refers to the distance of the air flow between the refrigeration assembly 300 and the storage cavity 101.

[0328] Referring to FIG. 23, in some embodiments, the third plate 230 forms the return air cavity 231 on the side facing the storage cavity 101, and the return air cavity 231 can be filled with gas. The return air cavity 231 filled with gas can be used as air isolation to effectively isolate the refrigeration assembly 300 and the storage cavity 101, thereby avoiding the direct influence of the refrigeration assembly 300 on the temperature in the storage cavity 101, and helping to ensure the uniformity of the temperature in the storage cavity 101.

[0329] Referring to FIG. 24, the return air cavity 231 is in communication with the storage cavity 101, and the return air cavity 231 and the storage cavity 101 have a first communication position 231a. The air flow can pass through the first communication position 231a, enter the return air cavity 231 through the storage cavity 101, so as to ensure that the air flow can enter and fill the return air cavity 231.

[0330] The first channel 201 and the storage cavity 101 also have a second communication position 231b, and the first communication position 231a is located upstream of the second communication position 231b in the flow direction of the air flow.

[0331] The air flow can pass through the second communication position 231b, enter the storage cavity 101 through the first channel 201, so that the air flow can first pass through the first communication position 231a to enter the return air cavity 231, and then pass through the second communication position 231b to enter the first channel 201 after filling the return air cavity 231, so as to ensure the circulation of the air flow.

[0332] Referring to FIG. 25, in some embodiments, the fan 250 includes a first fan 251, which is located in the first channel 201 and is configured to drive the air flow in the first channel 201 to flow to the air mixing channel 203. In this way, the first fan 251 can drive the air flow in the first channel 201 to flow, thereby forming the circulation of the air flow.

[0333] In some embodiments, the first fan 251 is, for example, a centrifugal fan, which has the characteristics of high efficiency and high air pressure, and can provide stable air flow under a large air volume, which helps to maintain the stability of the air flow in the first channel 201 and ensures that the air flow can be effectively transported and discharged.

[0334] Referring to FIG. 25, in some embodiments, the third plate 230 includes a mounting section 232 configured to mount the first fan 251, and the mounting section 232 is arranged along an Archimedes spiral. By generating a structure profile through a curve equation, the centrifugal pressure and efficiency can be improved.

[0335] Referring to FIG. 24, in some embodiments, the third plate 230 also has an auxiliary channel 209. The auxiliary channel 209 is formed in the lower part of the third plate 230 and penetrates the lower part of the second plate 220. The input end of the auxiliary channel 209 is in communication between the storage cavity 101 and the first channel 201, for example, the input end of the auxiliary channel 209 is in communication with the first communication position 231a. The return air cavity 231 is in communication with the intermediate position of the auxiliary channel 209, for example, the return air cavity 231 is in communication with the second communication position 231b.

[0336] At this time, the air flow process is as follows:

[0337] The air flow in the storage cavity 101 enters the auxiliary passage 209 under the action of the fan 250, enters the return air cavity 231 through the first communication position 231a, and fills the return air cavity 231 until the return air cavity 231 is filled with air flow. Then, the air flow enters the first passage 201 through the second communication position 231b located downstream to circulate the air flow.

[0338] The auxiliary passage 209 in some embodiments of the present disclosure can realize the filling of the return air cavity 231, and the return air cavity 231 filled with air can serve as air isolation, effectively isolating the refrigeration assembly 300 from the storage cavity 101, avoiding the direct influence of the refrigeration assembly 300 on the temperature in the storage cavity 101, and helping to ensure the uniformity of the temperature in the storage cavity 101.

[0339] Referring to FIG. 26, in some embodiments, the air flow circulation assembly 200 includes the aforementioned first plate 210, the second plate 220, the third plate 230, and the fourth plate 240, and the first plate 210 and the second plate 220 form two second sub-passages 202B. The first sub-passage 202A is located at the bottom of the storage cavity 101, and the first sub-passage 202A is located upstream of the second sub-passage 202B. The output ports of the two second sub-passages 202B are connected. The second plate 220 and the third plate 210 form the first passage 201. The first plate 210 has a first return air port 205 corresponding to the first passage 201 and a second return air port 206 corresponding to the two second sub-passages 202B.

[0340] The first return air port 205 is connected to the middle position of the lower part of the storage cavity 101. For example, the first return air port 205 can be connected to the auxiliary passage 209.

[0341] Referring to FIG. 26, part of the air flow a1 in the storage cavity 101 enters the auxiliary passage 209 through the first return air port 205. After the return air cavity 231 between the second plate 220 and the third plate 230 is filled, part of the air flow a1 enters the first passage 201.

[0342] Referring to FIGS. 26 and 27, in the case where the refrigeration assembly 300 includes an evaporator 310, the evaporator 310 is arranged close to the input port of the first passage 201. The evaporator 310 cools and dehumidifies the air flow. The output side of the evaporator 310 is provided with a second fan 252. The second fan 252 is a centrifugal fan, which can suck the air flow output by the evaporator 310 and guide the air flow to the air mixing passage 203.

[0343] The second return air port 206 is connected to the two sides of the lower part of the storage cavity 101 and the output side of the humidification assembly 500.

[0344] Referring to FIG. 26, the humidification assembly 500 outputs humidified air flow a3, which enters the second sub-passage 202B through the second return air port 206.

[0345] At this time, the other part of the air flow a2 in the storage cavity 101 and the humidified air flow a3 output by the humidifying assembly 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, which can guide the air flow to the mixing channel 203.

[0346] Here, the two heating assemblies 400 are arranged close to the output ports of the two second sub-channels 202B, which can increase the temperature of the air flow passing through the two second sub-channels 202B. In this way, the first channel 201 outputs a cooled and dehumidified air flow a4, and the second sub-channel 202B outputs a heated and humidified air flow a5.

[0347] The two air flows (such as the air flow a4 and the air flow a5) enter the first guide channel 262 and the second guide channel 263 formed by the first guide structure 260 respectively. The two air flows change in flow rate and complete preliminary mixing in the mixing guide channel 261.

[0348] The second guide structure 270 receives the air flow output by the first guide structure 270. The air flow passes through the first turning channel 271 formed by the adjacent first turning plate 273, the Reynolds number of the air flow changes, and the air flow changes from laminar flow to turbulent flow, which enhances the mixing degree of the two air flows. The air flow output by the first turning channel 271 enters the second turning channel 272 formed by the adjacent second turning plate 274 in the second guide structure 270 after being temporarily in the mixing channel 203, and the air flow changes from turbulent flow to laminar flow.

[0349] The third guide structure 280 receives the air flow a6 output by the second turning channel 272. The third guide structure 280 forms a first guide-out channel 281 and a second guide-out channel 282. The output port of the first guide-out channel 281 is located above the output port of the second guide-out channel 282. The air flow a6 becomes the air flow a7 through the output port of the first guide-out channel 281, and the air flow a7 enters the storage cavity 101 through the first air outlet 207. The air flow a6 becomes the air flow a8 through the output port of the second guide-out channel 282, and the air flow a8 enters the storage cavity 101 through the first air outlet 207.

[0350] In the mixing channel 203 of the air flow circulating assembly 200, the size of the physical parameter of the air flow output by the mixing channel 203 is between the physical parameter of the air flow in the storage cavity 101 and the physical parameter of the air flow received by the mixing channel 203.

[0351] The physical parameter fluctuation between the air flow a7 and a8 received by the storage cavity 101 and the air flow a1 and a2 released is small. In this way, the physical parameter of the air flow changes multiple times while the air flow flow time remains unchanged. Compared with single change, the adjustment accuracy of the physical parameter of the air flow is increased, the deviation between the actual air flow and the target air flow is reduced, the storage condition of the physical parameter of the air flow in the storage cavity 101 is constant, and the air flow in the storage cavity 101 can be located in the preset range, thereby facilitating the storage of the articles.
