[0023] The following will be combined with the accompanying drawings to clearly and completely describe some embodiments of the present disclosure. Obviously, the embodiments described are only some embodiments of the present disclosure, not all embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present disclosure.

[0024] The use of "adapted to" or "configured to" herein is intended to be open and inclusive language that does not exclude devices adapted or configured to perform additional tasks or steps.

[0025] Unless the context requires otherwise, throughout the specification and claims, the term "comprise" and its other forms, such as the third person singular form "comprises" and the present participle form "comprising", are to be interpreted as open and inclusive, that is, "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "example", "specific example" or "some examples" are intended to indicate that the particular features, structures, materials or characteristics associated with the embodiment or example are included in at least one embodiment or example of the present disclosure. The schematic representation of the above terms does not necessarily refer to the same embodiment or example. In addition, the particular features, structures, materials or characteristics may be included in any one or more embodiments or examples in any appropriate manner.

[0026] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present disclosure, unless otherwise specified, "plurality" means two or more.

[0027] In the description of this application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0028] When describing some embodiments, the expressions "coupled" and "connected" and their derivatives are used. For example, when describing some embodiments, the term "connected" may be used to indicate that two or more components are in direct physical or electrical contact with each other. For another example, when describing some embodiments, the term "coupled" may be used to indicate that two or more components are in direct physical or electrical contact. However, the term "coupled" or "communicatively coupled" may also refer to two or more components that 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 contents of this document.

[0029] The air temperature inside a storage cabinet (such as a wine cabinet) can typically be maintained constant, meaning it generally meets the required storage temperature for wine. However, some alcoholic beverages (such as wine) require an appropriate humidity level. For example, the ideal humidity range for wine storage is [60% to 70%]. If the humidity level inside the cabinet falls below the minimum value of this range, the elasticity of the wine bottle's sealing stopper (such as a cork) will decrease, causing the bottle's opening to lose its seal. This allows air from outside the bottle to enter and react with the wine, causing it to deteriorate. Furthermore, the wine can evaporate through the gap between the sealing stopper and the bottle's opening, resulting in waste.

[0030] The locker is usually provided with a humidifying device to meet the humidity requirement of the internal environment thereof. The locker comprises a storage compartment configured to store items.

[0031] In some embodiments, the locker also includes a water storage box, which is located within the storage compartment and includes a humidifying blower. In this case, humidified air can be distributed within the storage compartment through natural evaporation of water from the water storage box or assisted by the humidifying blower, thereby improving the humidity within the storage compartment. However, this cannot be correlated with the locker's on / off status. For example, when the locker is in cooling mode, the air temperature within the storage compartment drops, causing water molecules in the air to condense, potentially resulting in a decrease in humidity within the storage compartment.

[0032] Related art provides a control method for regulating the air humidity within a locker's storage compartment by defrosting the locker or controlling the operation of a refrigeration fan. For example, the method controls the start and stop of a compressor and a refrigeration fan based on the air temperature and humidity within the locker compartment to achieve regulation of the air temperature and humidity within the locker compartment. However, this method cannot accurately and continuously maintain the air humidity within the locker compartment within a preset fluctuation range. Furthermore, the adjustment of the operating mode of the compressor and refrigeration fan can affect the locker's cooling efficiency.

[0033] To address the above issues, some embodiments of the present disclosure provide a locker 100 and a control method thereof. During the humidification process of the locker 100, the start and stop status of the locker's compressor and heater, as well as the open and closed status of the locker door, are monitored to control the humidity within the locker 100, thereby maintaining the air humidity within the locker 100 within a predetermined humidity range.

[0034] In some embodiments, as shown in FIG1 , a storage cabinet 100 includes a cabinet body 10 , which includes a first compartment 30 (ie, a storage compartment). The first compartment 30 is configured to store items.

[0035] 1 , the cabinet 10 further includes an opening 11 disposed on one side of the cabinet 10. For example, the side of the first compartment 30 facing the user is open to form the opening 11, so that the user can easily take items through the opening 11.

[0036] The storage cabinet 100 further includes a cabinet door 20 , which is pivotally connected to the opening 11 of the cabinet body 10 to open or close the cabinet body 10 .

[0037] In some embodiments, as shown in FIG1 , the first compartment 30 includes a first sub-storage compartment 35 and a second sub-storage compartment 36 . The second sub-storage compartment 36 is disposed below the first sub-storage compartment 35 .

[0038] In some embodiments, the first compartment 30 further includes a third sub-storage compartment 37, which is disposed below the second sub-storage compartment 36. For example, the second sub-storage compartment 36 may be located between the first sub-storage compartment 35 and the third sub-storage compartment 37.

[0039] In some embodiments, as shown in Figure 1, the cabinet 10 also includes a first partition 12, which is fixedly connected to the inner liner of the cabinet 10 and is arranged between the first sub-storage compartment 35 and the second sub-storage compartment 36. The first partition 12 is configured to separate the first sub-storage compartment 35 and the second sub-storage compartment 36.

[0040] In some embodiments, the cabinet 10 further includes a second partition 13, which is fixedly connected to the inner liner of the cabinet 10 and is arranged between the second sub-storage compartment 36 and the third sub-storage compartment 37. The second partition 13 is configured to separate the second sub-storage compartment 36 and the third sub-storage compartment 37.

[0041] In some embodiments, as shown in FIG. 3 , the locker 100 further includes at least one first sensor 50 (first humidity sensor). The at least one first sensor 50 is disposed in the first compartment 30 and is configured to detect the air humidity in the first compartment 30 .

[0042] When the at least one first sensor 50 includes a plurality of first sensors 50, the plurality of first sensors 50 are respectively disposed in the plurality of sub-storage compartments of the first compartment 30. For example, when the at least one first sensor 50 includes three first sensors 50, the three first sensors 50 are respectively disposed in the first sub-storage compartment 35, the second sub-storage compartment 36, and the third sub-storage compartment 37 to detect the air humidity in the corresponding sub-storage compartments.

[0043] In some embodiments, as shown in FIG4 , the cabinet 10 further includes at least one second compartment 70 (component storage compartment). The second compartment 70 is disposed on one side of the cabinet 10 (eg, the rear side of the cabinet in FIG1 ).

[0044] In some embodiments, as shown in FIG. 3 , the cabinet 10 further includes at least one first compartment cover 71 . The first compartment cover 71 is detachably connected to the second compartment 70 to open or close the second compartment 70 .

[0045] In some embodiments, as shown in FIG4 , the locker 100 further includes a refrigeration device 200. At least a portion of the refrigeration device 200 is disposed in the second compartment 70 and is configured to provide cooling to the first compartment 30 to reduce the compartment temperature of the first compartment 30 and maintain the interior of the first compartment 30 at a predetermined temperature (e.g., a low temperature).

[0046] 2 , the cabinet 10 further includes a third compartment 40 . The third compartment 40 is disposed below the third sub-storage compartment 37 .

[0047] In some embodiments, as shown in FIG2 , the refrigeration device 200 includes a compressor 41 , which is disposed in the third compartment 40 and configured to provide power for a refrigeration cycle of the locker 100 . In this way, the service life of the compressor 41 can be increased.

[0048] In some embodiments, the refrigeration device 200 further includes a condenser, which is disposed in the second compartment 70 and configured to liquefy the refrigerant by exchanging heat between outdoor air and the refrigerant transmitted in the condenser.

[0049] In some embodiments, the refrigeration device 200 further includes an expansion valve, which is disposed in the second compartment 70 and configured to regulate the flow of refrigerant in the pipeline of the locker.

[0050] In some embodiments, as shown in FIG. 4 , the refrigeration device 200 further includes an evaporator 42 . The evaporator 42 is disposed in the second compartment 70 and is configured to vaporize the refrigerant by exchanging heat between outdoor air and the refrigerant transmitted in the evaporator 42 .

[0051] The compressor, condenser, expansion valve, and evaporator perform a refrigerant cycle of the locker 100. The refrigerant cycle includes a series of processes involving compression, condensation, expansion, and evaporation, and circulates and supplies refrigerant to the conditioned side.

[0052] After being compressed by the compressor, the low-temperature, low-pressure gas refrigerant becomes a high-temperature, high-pressure gas refrigerant, which then flows into the condenser. The condenser condenses the high-temperature, high-pressure gas refrigerant into a high-pressure liquid refrigerant, releasing heat into the surrounding environment during the condensation process. The expansion valve throttles and reduces the pressure of the high-pressure liquid refrigerant, converting it into a low-pressure gas-liquid two-phase refrigerant. The evaporator absorbs heat from the surrounding environment and evaporates the low-pressure gas-liquid two-phase refrigerant to form a low-temperature, low-pressure gas refrigerant. This low-temperature, low-pressure gas refrigerant returns to the compressor, completing the refrigerant cycle.

[0053] In some embodiments, as shown in FIG4 , the refrigeration device 200 further includes a first fan 44 (cooling fan), which is disposed in the second compartment 70 . Thus, the operation of the first fan 44 can blow cold air generated by heat exchange with the evaporator into the first compartment 30 , thereby cooling the interior of the first compartment 30 .

[0054] In some embodiments, as shown in FIG4 , the refrigeration device 200 further includes a heater 43 (defrosting heater), which is disposed below the evaporator 42 and configured to remove frost generated on the surface of the evaporator 42. The heater 43 is activated at predetermined intervals and performs a defrosting operation to remove frost generated on the surface of the evaporator 42.

[0055] In some embodiments, the refrigeration device 200 further includes a third sensor 45 (temperature sensor), which is disposed above the evaporator 42 and is configured to detect a defrost temperature. After the heater 43 is activated, if the defrost temperature is determined to be equal to a preset temperature, defrosting is stopped and the locker resumes refrigeration.

[0056] In some embodiments, as shown in FIG3 , the cabinet 10 further includes at least one first opening 34 (a third cooling opening). The at least one first opening 34 is provided on the first compartment cover 71 . Cold air generated by the refrigeration device 200 enters the first compartment 30 through the first opening 34 to meet the ambient temperature requirements of the multiple sub-storage compartments of the first compartment 30 .

[0057] In some embodiments, as shown in FIG. 1 and FIG. 5 , the locker 100 further includes a humidifying device 60 . The humidifying device 60 is disposed in the cabinet body 10 . The humidifying device 60 is configured to generate humid air and adjust the air humidity inside the first compartment 30 .

[0058] In some embodiments, as shown in Figures 5 and 6, the humidifying device 60 includes a first water storage box 62 (small water box), which stores water and is configured to provide humidified air to at least one of the first sub-storage compartment 35 or the second sub-storage compartment 36.

[0059] 1 , the first water storage box 62 further includes a second opening 32 (air inlet), which is provided on the water storage box cover of the first water storage box 62. The humidifying device 60 extracts air from the first chamber 30 through the second opening 32.

[0060] In some embodiments, as shown in FIG1 , the first water storage box 62 further includes a third opening 33 (air outlet). After the air in the first chamber 30 is humidified by the first water storage box 62, the humidified air is output to the first chamber 30 through the third opening 33. In this way, the air in the first chamber 30 can be humidified.

[0061] In some embodiments, as shown in FIG5 and FIG6 , the humidifying device 60 further includes a second water storage box 61 (large water box), which is disposed on the inner bottom wall of the cabinet 10 and configured to replenish water for the first water storage box 62 .

[0062] In some embodiments, the humidifying device 60 further includes a water injection pipe 64 (water pipe), and the second water storage box 61 is connected to the first water storage box 62 through the water injection pipe 64 .

[0063] The humidifier 60 further includes a water injection pump 65 (water pump), which is provided on the water injection pipe 64 and is configured to pump the water in the second water storage box 61 to the first water storage box 62. The water injection pump 65 operates at predetermined intervals to inject the water in the second water storage box 61 into the first water storage box 62 through the water injection pipe 64.

[0064] In some embodiments, the capacity of the second water storage box 61 is greater than that of the first water storage box 62 , so that the total humidification time of the humidifying device 60 on the water storage compartment can be increased.

[0065] In some embodiments, as shown in FIG5 , the second water storage box 61 further includes a water inlet 67 , which is a through hole. When the second water storage box 61 is short of water, water can be replenished through the water inlet 67 .

[0066] The humidifier 60 also includes an external water pipe 68. A first end of the external water pipe 68 is connected to the water inlet 67, and a second end of the external water pipe 68 is connected to an external water source. The second water storage box 61 is connected to the external water source via the external water pipe 68. For example, the external water source can be a reservoir, a pool, or the like.

[0067] In some embodiments, the humidifier 60 further includes a water valve 66, which is disposed on an external water pipe 68 and is configured to control the opening and closing of the external water pipe 68 to control the filling of the second water storage box 61. When the water valve 66 is open, water from the external water source can be injected into the second water storage box 61 through the external water pipe 68.

[0068] In some embodiments, the humidifying device 60 further includes a fourth sensor 63 (liquid level sensor). The fourth sensor 63 is disposed in the first water storage box 62 and is configured to detect the water level in the first water storage box 62 .

[0069] In some embodiments, the humidifying device 60 further includes a second fan (humidifying fan, i.e., fan), which is disposed in the first water storage box 62 and is configured to blow air toward the first water storage box 62 to blow the humid air in the first water storage box 62 to the first chamber 30.

[0070] In some embodiments, the storage cabinet 100 also includes a controller, which is coupled to the humidifying device 60 and the refrigeration device 200 to realize information collection, calculation and analysis, and output of control instructions, thereby controlling the operating parameters of the refrigeration device 200, the start-up or shutdown of the humidifying device 60, and other start-up and stop states.

[0071] In some embodiments, as shown in FIG. 7 , the controller is configured to perform S10 to S19 .

[0072] S10. Start the process.

[0073] S11. Determine whether the locker 100 is not powered on for the first time. If so, execute S12; if not, execute other control processes.

[0074] It should be noted that, when the time duration that the locker 100 is in the unpowered state is less than the preset time duration, or when the locker 100 remains in the powered-on state, the controller determines that the locker 100 is not powered-on for the first time; when the time duration that the locker 100 is in the unpowered state is greater than or equal to the preset time duration, the controller determines that the locker 100 is powered-on for the first time.

[0075] When the controller determines that the locker 100 is not powered on for the first time, the controller cannot obtain the accurate current humidity of the first compartment 30 .

[0076] Other control processes include, for example, a control process for the controller to start and stop the humidifier 60 when the locker 100 is powered on for the first time.

[0077] S12: Obtain the current humidity of the air in the first chamber 30.

[0078] When the controller determines that the locker 100 is not powered on for the first time, indicating that the locker 100 has been running for longer than a preset time, the air temperature and humidity in the first compartment 30 are stable, and the controller obtains the current humidity of the first compartment 30 through the first sensor.

[0079] In some embodiments, since the sub-storage compartments of the first compartment 30 are interconnected, the air temperature and humidity in each sub-storage compartment are substantially the same. The controller may obtain multiple air humidities detected by multiple first sensors 50 disposed in different sub-storage compartments and use the average of the multiple air humidities as the current humidity of the first compartment 30.

[0080] S13: Determine whether the current humidity is less than a first preset threshold value. If so, execute S14; if not, execute other control processes.

[0081] In some embodiments, the air humidity level in the first chamber 30 is divided into three standards, namely a first preset threshold, a second preset threshold, and a third preset threshold.

[0082] The first preset threshold corresponds to, for example, a preset low humidity level for the first compartment 30. The first preset threshold can be any value between [50%, 60%), for example, 50%, 55%, or 59%. This can satisfy different user requirements for setting a low humidity level for the first compartment 30.

[0083] When the current humidity of the air in the first chamber 30 is less than the first preset threshold, that is, when the current humidity of the first chamber 30 is less than a value within the value range of the first preset threshold (such as 55%), it means that the humidity of the air in the first chamber 30 is lower than the predetermined humidity, and the first chamber 30 needs to be humidified.

[0084] The second preset threshold corresponds to the preset intermediate humidity of the first compartment 30. The second preset threshold can be any value between [60% and 70%]. The second preset threshold can be 60%, 65%, or 70%. This can meet different user requirements for setting the intermediate humidity of the first compartment 30.

[0085] When the current humidity of the air in the first chamber 30 is equal to a value (such as 60%) within the value range of the second preset threshold, humidification of the first chamber 30 is continued or stopped according to demand.

[0086] The third preset threshold corresponds to the high preset humidity of the first chamber 30. The value of the third preset threshold can be any value between [70%, 80%]. The value of the third preset threshold is 72%, 75%, or 80%. In this way, different requirements of users for the setting value of the high humidity of the first chamber 30 can be met.

[0087] If the current humidity of the air in the first compartment 30 is greater than the third preset threshold, that is, if the current humidity of the first compartment 30 is greater than a value within the value range of the third preset threshold (e.g., 75%), it indicates that the humidity of the air in the first compartment 30 is high and may damage the items in the first compartment 30. If the third preset range is less than or equal to the third preset threshold, it indicates that the humidity of the air in the first compartment 30 has not reached the high preset humidity.

[0088] It is understandable that the classification standard for the air humidity levels in the first chamber 30 can be determined according to actual needs.

[0089] For example, another control process is a control process in which the controller starts the humidifying device 60 when the current humidity is greater than or equal to the first preset threshold.

[0090] S14 , obtaining the start / stop status of the heater 43 and the open / close status of the cabinet door 20 .

[0091] The controller obtains the start / stop state of the heater 43 and the open / close state of the cabinet door 20 to prevent the start / stop state of the heater 43 and the open / close state of the cabinet door 20 from affecting the humidity of the first chamber 30 .

[0092] It is understandable that when the current humidity is less than the first preset threshold, the humidity requirement of the first chamber 30 needs to be met first. At this time, the control of the temperature of the first chamber 30 can be suspended. Therefore, the monitoring of the start and stop status of the compressor 41 can be stopped, but the opening and closing status of the cabinet door 20 and the start and stop status of the heater 43 need to be determined.

[0093] S15: Determine whether the heater 43 is in the shutdown state. If so, execute S16; if not, execute S18.

[0094] If the controller determines that the heater 43 is in operation, it indicates that the locker 100 is performing a defrosting operation. At this time, the heater 43 heats the frost layer condensed on the surface of the evaporator 42. The high temperature melts the frost layer and generates a large amount of humid air. Some of this humid air enters the first chamber 30 through the first opening 34, causing the humidity in the first chamber 30 to increase. This can cause a discrepancy between the current humidity of the first chamber 30 obtained by the controller and the actual humidity.

[0095] When the controller determines that the heater 43 is in the shutdown state, it indicates that the frost layer on the surface of the evaporator 42 will not affect the air humidity in the first chamber 30 .

[0096] S16: Determine whether the cabinet door 20 is in a closed state. If so, execute S17; if not, execute S18.

[0097] In some embodiments, when the humidity of the air outside the locker 100 is greater than the humidity of the air inside the locker 100 and the controller determines that the door 20 is open, the high-humidity air outside the locker 100 mixes with the low-humidity air inside the first chamber 30, causing the humidity of the air inside the first chamber 30 to increase.

[0098] In other embodiments, when the humidity of the air outside the locker 100 is lower than the humidity of the air inside the locker 100 and the controller determines that the door 20 is open, the low-humidity air outside the locker 100 mixes with the air in the first chamber 30, resulting in a decrease in the humidity of the air in the first chamber 30.

[0099] In this way, when the air outside the locker 100 and the air inside the first chamber 30 are not evenly mixed, the current humidity of the first chamber 30 detected by the first sensor 50 and obtained by the controller may deviate from the actual humidity.

[0100] When the controller determines that the cabinet door 20 is in the closed state, it indicates that the air humidity outside the locker 100 will not affect the air humidity in the first chamber 30 .

[0101] S17, controlling the humidifying device 60 to start.

[0102] The controller controls the humidifying device 60 to start up, so as to humidify the air in the first chamber 30 .

[0103] S18: Control the humidifying device 60 to stop running.

[0104] During the operation of the humidifier 60, the controller continuously monitors the start / stop status (operating status) of the heater 43 and the opening / closing status (operating status) of the cabinet door 20. When at least one of the conditions is satisfied: the heater 43 is in the operating state or the cabinet door 20 is in the open state, the controller controls the humidifier 60 to stop operating to prevent damage to items in the first chamber 30 due to high humidity in the first chamber 30.

[0105] S19. End the process.

[0106] In other embodiments, the execution order of S15 and S16 can be interchanged, or they can be executed simultaneously. For example, after executing S14, the controller can first execute S16 and then execute S15. For another example, the controller can execute S15 and S16 simultaneously. The execution steps are similar to those described above and are not repeated here.

[0107] The control method in some embodiments of the present disclosure includes: when the locker is not powered on for the first time, obtaining the current humidity detected by the first sensor 50; when the current humidity is less than a first preset threshold, obtaining the start and stop status of the heater 43 and the opening and closing status of the cabinet door 20; when the heater 43 is in the shutdown state and the cabinet door 20 is in the closed state, the controller controls the humidification device 60 to start; when at least one of the heater 43 is in the running state or the cabinet door 20 is in the open state, the controller controls the humidification device 60 to stop running.

[0108] In some embodiments, as shown in FIG8 , after executing S17 , the controller is further configured to execute S20 to S28 .

[0109] S20: Determine whether the current humidity is greater than or equal to a second preset threshold. If so, execute S21; if not, continue to execute S17.

[0110] S21 , acquiring the open / close state of the cabinet door 20 , the start / stop state of the compressor 41 , and the start / stop state of the heater 43 .

[0111] After the controller starts the humidifier 60, the current humidity of the air in the first chamber 30 increases. When the current humidity of the air in the first chamber 30 is greater than or equal to the second preset threshold, the controller obtains the open / closed state of the cabinet door 20, the start / stop state of the compressor 41, and the start / stop state of the heater 43 to prevent the open / closed state of the cabinet door 20, the start / stop state of the compressor 41, and the start / stop state of the heater 43 from affecting the humidity in the first chamber 30.

[0112] S22: Determine whether the compressor 41 is in a shutdown state. If so, execute S23; if not, execute S27.

[0113] It should be noted that when the controller determines that the compressor 41 is in operation, the refrigeration unit 200 operates, and the cold air generated after heat exchange with the evaporator 42 enters the first chamber 30 through the first opening 34, causing the air humidity to decrease. Therefore, during the cooling process, the air humidity in the first chamber 30 decreases. This can cause a deviation between the current humidity of the first chamber 30 obtained by the controller and the actual humidity value.

[0114] When the controller determines that the compressor 41 is in the shutdown state, it indicates that the air humidity in the first chamber 30 will not be affected by the refrigeration process.

[0115] S23, determine whether the heater 43 is in the shutdown state, if so, execute S24, if not, execute S27.

[0116] The controller's judgment on whether the heater 43 is in the shutdown state is similar to that in S15 and will not be repeated here.

[0117] S24: Determine whether the cabinet door 20 is in a closed state. If so, execute S25; if not, execute S27.

[0118] The controller's judgment on whether the cabinet door 20 is in a closed state is similar to that in S16 and will not be repeated here.

[0119] S25: Control the humidifying device 60 to continue operating.

[0120] When the compressor 41 is in the stopped state, the heater 43 is in the stopped state, and the cabinet door 20 is in the closed state, the controller controls the humidifying device 60 to continue to operate, so as to continue to humidify the first chamber 30 .

[0121] S26: Determine whether the current humidity is greater than or equal to a third preset threshold. If so, execute S27; if not, continue to execute S25.

[0122] It is understandable that as the storage time of the items in the first chamber 30 increases, the items will consume the humidity of the air in the first chamber 30. Moreover, during the cooling process of the compressor 41, the humidity of the air in the first chamber 30 decreases. However, when the humidity of the air in the first chamber 30 is greater than the third preset threshold range, the reduction in the humidity of the air in the first chamber 30 caused by the cooling of the compressor 41 is small, and the current humidity of the first chamber 30 is already greater than the second preset threshold. Therefore, the controller controls the humidifier 60 to stop operating, so that the air temperature in the first chamber 30 meets the required level. This prevents the simultaneous operation of the humidifier 60 and the cooling device 200 from prolonging the cooling process of the air in the first chamber 30, thereby facilitating energy conservation.

[0123] S27: Control the humidifying device 60 to stop running.

[0124] The controller controls the humidifier 60 to stop operating if at least one of the following conditions is met: the compressor 41 is operating, the heater is operating, or the cabinet door 20 is open. Furthermore, if the current humidity in the first compartment 30 is greater than or equal to a third preset threshold, indicating that the humidity in the first compartment 30 has reached a high preset humidity, the controller controls the humidifier 60 to stop operating. This prevents damage to items in the first compartment 30 due to excessive humidity and saves energy.

[0125] S28. End the process.

[0126] In other embodiments, the execution order of S22, S23, and S24 can be interchanged or performed simultaneously. For example, after executing S22, the controller may first execute S24 and then execute S23. For another example, after executing step S21, the controller may first execute at least one of S23 or S24 and then execute S22. For another example, the controller may execute S22, S23, and S24 simultaneously. The above description is similar and will not be repeated here.

[0127] In some embodiments of the present disclosure, a control method is applied to a controller. The control method includes: if it is determined that the current humidity of the first compartment 30 is greater than or equal to a second preset threshold, the compressor 41 is in a stopped state, the heater 43 is in a stopped state, and the cabinet door is closed, then controlling the humidifier 60 to continue operating. If it is determined that the current humidity of the first compartment 30 is greater than or equal to a third preset threshold, then controlling the humidifier 60 to stop operating.

[0128] In some embodiments, as shown in FIG9 , after executing S12 , the controller is further configured to execute S31 to S39 .

[0129] S31. Determine whether the current humidity is greater than or equal to a first preset threshold and less than a second preset threshold. If so, execute S32; if not, execute other control processes.

[0130] The controller obtains the current humidity of the first chamber 30. When the current humidity is greater than or equal to a first preset threshold and less than a second preset threshold, it indicates that the humidity of the first chamber 30 is low and a humidification operation can be performed.

[0131] For example, another control process is that when the current humidity is less than the first preset threshold, the controller controls the start and stop of the humidifying device 60.

[0132] S32 , acquiring the open / close state of the cabinet door 20 , the start / stop state of the compressor 41 , and the start / stop state of the heater 43 .

[0133] The controller obtains the opening and closing state of the cabinet door 20 , the start and stop state of the compressor 41 , and the start and stop state of the heater 43 to prevent the opening and closing state of the cabinet door 20 , the start and stop state of the compressor 41 , and the start and stop state of the heater 43 from affecting the humidity of the first chamber 30 .

[0134] S33: Determine whether the compressor 41 is in a shutdown state. If so, execute S34; if not, execute S38.

[0135] The controller's judgment on whether the compressor 41 is in the shutdown state is similar to that in S22 and will not be repeated here.

[0136] S34: Determine whether the heater 43 is in the shutdown state. If so, execute S35; if not, execute S38.

[0137] The controller's judgment on whether the heater 43 is in the shutdown state is similar to that in S15 and will not be repeated here.

[0138] S35. Determine whether the cabinet door 20 is in a closed state. If so, execute S36; if not, execute S38.

[0139] The controller's judgment on whether the cabinet door 20 is in a closed state is similar to that in S16 and will not be repeated here.

[0140] S36: Control the humidifying device 60 to continue operating.

[0141] When the compressor 41 is in the stopped state, the heater 43 is in the stopped state, and the cabinet door 20 is in the closed state, the controller controls the humidifying device 60 to continue operating to humidify the first chamber 30 .

[0142] S37: Determine whether the current humidity is greater than or equal to a third preset threshold value. If so, execute S38; if not, continue to execute S32.

[0143] It is understood that, during the process of the current humidity increasing from the second preset threshold to the third preset threshold, the controller monitors the open and closed state of the cabinet door 20 and the start and stop states of the compressor 41 and the heater 43 to prevent the open and closed state of the cabinet door 20, the start and stop states of the compressor 41, and the start and stop states of the heater 43 from affecting the humidity of the first chamber 30.

[0144] S38: Control the humidifying device 60 to stop running.

[0145] When the controller detects that the compressor 41 is in operation and the air humidity in the first chamber 30 is greater than or equal to the first preset threshold and less than the third preset threshold, the controller controls the humidifying device 60 to stop operating.

[0146] S39. End the process.

[0147] In other embodiments, the execution order of S33, S34, and S35 can be interchanged or performed simultaneously. For example, after executing S33, the controller may first execute S35 and then execute S34. For another example, after executing step S32, the controller may first execute at least one of S34 or S35 and then execute S33. For another example, the controller may execute S33, S34, and S35 simultaneously. The above description is similar and will not be repeated here.

[0148] In some embodiments of the present disclosure, the control method includes: if it is determined that the current humidity is greater than or equal to a first preset threshold and less than a second preset threshold, obtaining the open / closed state of the cabinet door 20 and the start / stop state of the compressor 41 and the heater 43. If the compressor 41 is in the stopped state, the cabinet door 20 is in the closed state, and the heater 43 is in the stopped state, controlling the humidifier 60 to start; if it is determined that the current humidity of the first chamber 30 is greater than or equal to a third preset threshold, controlling the humidifier 60 to stop operating.

[0149] In some embodiments, as shown in FIG10 , after executing S11 , the controller is further configured to execute S41 to S46 .

[0150] S41 , determining whether the locker 100 is powered on for the first time.

[0151] S42: Control the humidifying device 60 to start.

[0152] It should be noted that when the locker 100 is powered on for the first time, the air temperature and humidity inside the locker 100 are unstable. At this time, the controller controls the humidifier 60 to humidify the first chamber 30 to shorten the time it takes for the air temperature and humidity inside the first chamber 30 to meet the requirements.

[0153] S43: Obtain the current humidity of the first chamber 30.

[0154] The controller obtains the current humidity of the first chamber 30 through the first sensor 50 .

[0155] S44: Determine whether the current humidity is greater than or equal to a third preset threshold value. If so, execute S45; if not, continue to execute S42.

[0156] If the current humidity is greater than or equal to the third preset threshold, it indicates that the humidity in the first chamber 30 has reached the high preset humidity. At this time, the controller controls the humidifier 60 to stop operating. This can prevent damage to items in the first chamber 30 due to excessive humidity and save energy.

[0157] S45: Control the humidifying device 60 to stop running.

[0158] In some embodiments, after executing S45 , the controller executes S21 to S25 , or S31 to S35 , according to the relationship between the current humidity of the air in the first chamber 30 and the second preset threshold.

[0159] S46. End the process.

[0160] In some embodiments, the storage cabinet 100 further includes a dehumidification device.

[0161] It should be noted that when the heater 43 is activated and performing a defrost operation or when the cabinet door 20 is open, the humidity of the air within the first compartment 30 will change. If the humidity within the first compartment 30 is greater than or equal to a third preset threshold and persists for a duration greater than a preset threshold (e.g., 1 hour), the controller controls the dehumidifier to operate to dehumidify the air within the first compartment 30. If the humidity falls below the third preset threshold, the dehumidifier is turned off. This prevents damage to items in the first compartment 30 and protects the components of the locker 100.

[0162] In some embodiments, as shown in FIG. 11 , the controller is further configured to execute S50 to S60 .

[0163] S50, start the process.

[0164] S51. Determine whether the cabinet door 20 is in an open state. If so, execute S52; if not, continue to execute S51.

[0165] S52: Obtain the current humidity of the first chamber 30.

[0166] The controller obtains the current humidity of the air in the first chamber 30 through the first sensor 50 .

[0167] It should be noted that the current humidity obtained by the controller when the cabinet door 20 is opened may represent the humidity of the air in the first chamber 30 before the cabinet door 20 is opened.

[0168] S53: Determine whether the cabinet door 20 is in a closed state. If so, execute S54; if not, continue to execute S52.

[0169] When the controller determines that the cabinet door 20 is in the closed state, it indicates that the locker 100 has experienced a "door opening-door closing" cycle. The duration of this cycle is the duration of the cabinet door 20 being open.

[0170] S54: Record the opening time of the cabinet door 20 and obtain the current ambient humidity.

[0171] In some embodiments, the controller includes a timing component, and uses the timing component to record the opening time of the cabinet door 20. For example, when the controller detects that the cabinet door 20 is in the open state, the timing component starts and starts timing, and when the controller detects that the cabinet door 20 is in the closed state, the timing component stops.

[0172] In some embodiments, the locker 100 further includes a second sensor (second humidity sensor), which is disposed outside the locker 100 and configured to detect the humidity of the environment in which the locker 100 is located. The controller obtains the current humidity of the environment through the second sensor.

[0173] S55: Calculate the standard humidity of the air in the first chamber 30 according to the current humidity, the opening time, and the current ambient humidity.

[0174] In some embodiments, the standard humidity can be calculated based on the current humidity, the duration of the on time, the current ambient humidity, and formula (1). D = Dj + (Dh - Dj) × t × k Formula (1)

[0175] Here, D is the standard humidity of the first chamber 30; Dj is the current humidity of the first chamber 30; Dh is the current ambient humidity; t is the opening time; and k is the humidity coefficient. For example, k is a constant.

[0176] S56: Determine whether the standard humidity is less than a first preset threshold value. If so, execute S57; if not, execute S58.

[0177] When the current humidity of the first chamber 30 is less than the first preset threshold, it means that the air humidity in the first chamber 30 is low and the first chamber 30 needs to be humidified.

[0178] S57: Control the second fan to operate at the first speed.

[0179] The first speed is the high speed of the second fan. Here, the first speed can be any value in the range [1.5PMW, 2PMW], for example, 1.5PMW, 1.6PMW, 1.7PMW, 1.8PMW, 1.9PMW, or 2PMW. This can meet different user requirements for the high speed setting value of the second fan.

[0180] When the standard humidity is less than the first preset threshold, the controller controls the second fan to operate at the first speed to increase the efficiency of humidifying the air in the first chamber 30 .

[0181] S58: Determine whether the standard humidity is greater than or equal to the first preset threshold and less than the second preset threshold. If so, execute S59; if not, execute other control processes.

[0182] For example, another control process is that when the standard humidity is greater than or equal to the second preset threshold, the controller controls the start and stop of the humidifying device 60.

[0183] S59: Control the second fan to operate at a second speed.

[0184] The second speed is the low speed of the second fan and is lower than the first speed. The second speed can be any value in the range [1.0 PMW, 1.2 PMW], for example, 1.0 PMW, 1.1 PMW, or 1.2 PMW. This can meet different user requirements for the low speed setting value of the second fan.

[0185] When the standard humidity is greater than or equal to the first preset threshold and less than the second preset threshold, it indicates that the air humidity in the first chamber 30 is moderate. At this time, the controller controls the second fan to operate at the second speed.

[0186] It is understandable that increasing the rotation speed of the second fan can improve the efficiency of humidifying the air in the first chamber 30 .

[0187] S60: End the process.

[0188] In this way, the problem that the current humidity of the air in the first chamber 30 detected by the first sensor 50 cannot accurately reflect the actual humidity because the cabinet door 20 is in the open state and the air from outside the first chamber 30 and the air in the first chamber 30 have not yet been evenly mixed can be solved.

[0189] In some embodiments of the present disclosure, a control method is applied to a controller, and the control method includes: if it is determined that the cabinet door 20 is in an open state, obtaining the current humidity of the first chamber 30; if it is determined that the cabinet door 20 is in a closed state, recording the opening time of the cabinet door 20, obtaining the current ambient humidity, and calculating the standard humidity of the air in the first chamber 30 based on the current humidity, the opening time, and the current ambient humidity; if it is determined that the standard humidity is less than a first preset threshold, controlling the second fan to operate at a first speed; if it is determined that the standard humidity is greater than or equal to the first preset threshold and less than a second preset threshold, controlling the second fan to operate at a second speed.

[0190] In some embodiments, as shown in FIG. 12 , after the controller executes S60 , it is further configured to execute S61 to S70 .

[0191] S61 : Obtain the current humidity of the first chamber 30 .

[0192] The controller obtains the current humidity of the first chamber 30 through the first sensor 50 .

[0194] S63 , acquiring the open / close state of the cabinet door 20 , the start / stop state of the compressor 41 , and the start / stop state of the heater 43 .

[0195] The controller obtains the opening and closing state of the cabinet door 20 , the start and stop state of the compressor 41 , and the start and stop state of the heater 43 to prevent the opening and closing state of the cabinet door 20 , the start and stop state of the compressor 41 , and the start and stop state of the heater 43 from affecting the humidity of the first chamber 30 .

[0196] S64: Determine whether the compressor 41 is in a shutdown state. If so, execute S65; if not, execute S69.

[0197] When the controller determines that the compressor 41 is in the shutdown state, it indicates that the air humidity in the first chamber 30 will not be affected by the refrigeration process.

[0198] S65: Determine whether the heater 43 is in the shutdown state. If so, execute S66; if not, execute S69.

[0199] The controller's judgment on whether the heater 43 is in the shutdown state is similar to that in S15 and will not be repeated here.

[0200] S66: Determine whether the cabinet door 20 is in a closed state. If so, execute S67; if not, execute S69.

[0201] The controller's judgment on whether the cabinet door 20 is in a closed state is similar to that in S16 and will not be repeated here.

[0202] S67: Control the second fan to maintain the current speed.

[0203] When the compressor 41 is in the stopped state, the heater 43 is in the stopped state, and the cabinet door 20 is in the closed state, the controller controls the second fan to maintain the current rotation speed to continue humidifying the first chamber 30 .

[0204] S68: Determine whether the current humidity is greater than or equal to a third preset threshold value. If so, execute S70; if not, continue to execute S63.

[0205] If the controller determines that the air humidity in the first chamber 30 is less than the third preset threshold, it indicates that the air humidity in the first chamber 30 has not reached the high preset humidity. At this time, the controller again obtains the open and closed status of the cabinet door 20, the start and stop status of the compressor 41, and the start and stop status of the heater 43, and continues to humidify the air in the first chamber 30 if the requirements are met.

[0206] S69: Control the second fan to stop running.

[0207] When at least one of the conditions that the compressor 41 is in operation, the heater 43 is in operation, or the cabinet door 20 is in operation is satisfied, the controller controls the second fan to stop operating.

[0208] S70: End the process.

[0209] When the controller determines that the current humidity of the first chamber 30 is greater than or equal to the third preset threshold, it indicates that the air humidity in the first chamber 30 meets the requirement, and the control process ends.

[0210] In other embodiments, the execution order of S64, S65, and S66 can be interchanged or performed simultaneously. For example, after executing S64, the controller may first execute S66 and then execute S65. For another example, after executing step S63, the controller may first execute at least one of S65 or S66 and then execute S64. For another example, the controller may execute S64, S65, and S66 simultaneously. Similar to the above, no further details are given here.

[0211] In some embodiments of the present disclosure, a control method is applied to a controller, and the control method includes: obtaining the current humidity of the first chamber 30; if it is determined that the current humidity of the air in the first chamber 30 is greater than or equal to a second preset threshold, obtaining the open / closed state of the cabinet door 20, the start / stop state of the compressor 41, and the start / stop state of the heater 43; if it is determined that the compressor 41 is in a stopped state, the heater 43 is in a stopped state, and the cabinet door 20 is in a closed state, controlling the second fan to maintain a current speed; if it is determined that the air humidity in the first chamber 30 is greater than or equal to a third preset threshold, the control process ends.

[0212] In some embodiments, as shown in FIG. 13 , after executing S55 , the controller is further configured to execute S81 to S89 .

[0213] S81. Determine whether the standard humidity is greater than or equal to the second preset threshold and less than the third preset threshold. If so, execute S82; if not, continue to execute S55.

[0214] S82 : Acquire the open / close state of the cabinet door 20 , the start / stop state of the compressor 41 , and the start / stop state of the heater 43 .

[0215] When the standard humidity of the air in the first chamber 30 is greater than or equal to a second preset threshold, the controller obtains the open / closed state of the cabinet door 20, the start / stop state of the compressor 41, and the start / stop state of the heater 43 to prevent the open / closed state of the cabinet door 20, the start / stop state of the compressor 41, and the start / stop state of the heater 43 from affecting the humidity in the first chamber 30.

[0216] S83: Determine whether the compressor 41 is in a shutdown state. If so, execute S84; if not, execute S88.

[0217] When the controller determines that the compressor 41 is in the shutdown state, it indicates that the air humidity in the first chamber 30 will not be affected by the refrigeration process.

[0218] S84: Determine whether the heater 43 is in the shutdown state. If so, execute S85; if not, execute S88.

[0219] The controller's judgment on whether the heater 43 is in the shutdown state is similar to that in S15 and will not be repeated here.

[0220] S85. Determine whether the cabinet door 20 is in a closed state. If so, execute S86; if not, execute S88.

[0221] The controller's judgment on whether the cabinet door 20 is in a closed state is similar to that in S16 and will not be repeated here.

[0222] S86. Control the operation of the second fan.

[0223] When the compressor 41 is in the stopped state, the heater 43 is in the stopped state, and the cabinet door 20 is in the closed state, the controller controls the second fan to operate to humidify the first chamber 30 .

[0224] S87: Determine whether the standard humidity is greater than or equal to a third preset threshold value. If so, execute S88; if not, continue to execute S82.

[0225] If the controller determines that the standard humidity of the air in the first chamber 30 is less than the third preset threshold, it indicates that the air humidity in the first chamber 30 has not reached the high preset humidity. At this time, the controller obtains the open / closed state of the cabinet door 20, the start / stop state of the compressor 41, and the start / stop state of the heater 43 again, and continues to humidify the air in the first chamber 30 if the requirements are met.

[0226] S88. Control the second fan to stop running.
