Description

Technical Field

[0001] This invention relates to the field of humidification product technology, and in particular to a storage cabinet and a humidification control method for the storage cabinet. Background Technology

[0002] As people's living standards improve, different items will be stored in different lockers, and the storage conditions of the lockers will be controlled to meet the storage needs of the items, such as wine cabinets, medicine cabinets, and refrigerators. Different items have different requirements for their own storage environment, such as temperature and humidity. For items with high humidity requirements, the humidity inside the locker cannot be too low or too high, otherwise it may affect the quality of the stored items.

[0003] Existing humidification systems typically require two water tanks: a large tank for storing water and a small tank to supply humidified air into the room. When the small tank runs out of water, a pump mechanism needs to draw water from the large tank to replenish it. Existing humidification systems are relatively complex and costly to manufacture, and the humidification effect is affected when either the large or small tank is dry and not replenished in time. Summary of the Invention

[0004] The purpose of this invention is to provide a storage cabinet and a humidification control method for the storage cabinet, which can effectively reduce the structural manufacturing cost of the humidification device and improve the humidification performance of the humidification device, thereby improving the user experience.

[0005] To achieve the above objectives, embodiments of the present invention provide a storage cabinet, comprising:

[0006] The cabinet has internal storage compartments.

[0007] A humidifying device is installed inside the cabinet to regulate the humidity of the storage room. The humidifying device includes a water storage box, humidifying fibers, and a fan. The humidifying fibers are located below the water storage box and communicate with the water outlet of the water storage box. A first water valve is provided at the water outlet of the water storage box. The humidifying fibers are also located at the air outlet of the storage room, and the fan is located outside the air outlet.

[0008] Controller, used for:

[0009] When the preset humidification start-up conditions are met, the first water valve is opened so that the water in the water storage box flows to the humidification fiber through the water outlet;

[0010] After the first period of time, the fan is started and runs at the target speed to drive the humidified air of the humidifying fiber into the storage room through the air outlet.

[0011] As an improvement to the above solution, the first duration is calculated based on the ratio of the preset water absorption of the humidifying fiber to the water flow velocity at the outlet of the water storage box, and the water flow velocity at the outlet of the water storage box is controlled by the opening degree of the first water valve.

[0012] As an improvement to the above solution, the controller is also used for:

[0013] Obtain the water flow velocity at the outlet of the water storage box;

[0014] The water consumption rate of the humidifying fiber is determined based on the water flow rate; the water consumption rate of the humidifying fiber is consistent with the water flow rate at the outlet of the water storage box.

[0015] The target rotational speed of the fan is calculated based on the water consumption rate of the humidifying fiber; the target rotational speed is positively correlated with the water consumption rate of the humidifying fiber.

[0016] As an improvement to the above solution, the water storage box is located in the top partition of the storage room, and the water outlet of the water storage box is connected to the humidifying fiber through a funnel structure. The water outlet of the water storage box is located at the top opening of the funnel structure, and the humidifying fiber is connected to the bottom opening of the funnel structure.

[0017] As an improvement to the above solution, the controller is also used for:

[0018] When the preset humidification stop condition is met, the first water valve and the fan are controlled to shut down.

[0019] As an improvement to the above solution, the locker also includes a humidity sensor, located inside the storage compartment, for collecting the humidity of the storage compartment;

[0020] The preset humidification start condition is: the current room humidity collected by the humidity sensor is less than or equal to the first humidity threshold.

[0021] The preset humidification stop condition is: the current room temperature collected by the humidity sensor is greater than or equal to the second humidity threshold.

[0022] As an improvement to the above solution, the water storage box is further provided with a water inlet and an external water pipe. The water inlet of the water storage box is connected to an external water source through the external water pipe, and a second water valve is provided at the water inlet; the controller is also used for:

[0023] Calculate the cumulative open duration of the first water valve;

[0024] When the cumulative open time of the first water valve is greater than or equal to the second time, the second water valve is controlled to open so that the external water source fills the water storage box, and the cumulative open time is reset to zero; wherein, the second time is calculated based on the ratio of the target water storage capacity of the water storage box to the water flow velocity at the outlet of the water storage box.

[0025] As an improvement to the above solution, the locker also includes a liquid level sensor, which is located at the liquid level height of the target water volume in the water storage box, and is used to send a full water signal when the water volume in the water storage box reaches the target water volume.

[0026] The controller is also used for:

[0027] When the full water signal is received, the second water valve is controlled to close.

[0028] As an improvement to the above solution, the storage cabinet also includes a refrigeration system for regulating the temperature of the storage compartment, and the fan is a refrigeration fan;

[0029] The preset humidification start-up conditions are: the current room humidity collected by the humidity sensor is less than or equal to the first humidity threshold, and the refrigeration system is not running.

[0030] This invention also provides a humidification control method for a storage cabinet, the storage cabinet comprising:

[0031] The cabinet has internal storage compartments.

[0032] A humidifying device is installed inside the cabinet to regulate the humidity of the storage room. The humidifying device includes a water storage box, humidifying fibers, and a fan. The humidifying fibers are located below the water storage box and communicate with the water outlet of the water storage box. A first water valve is provided at the water outlet of the water storage box. The humidifying fibers are also located at the air outlet of the storage room, and the fan is located outside the air outlet.

[0033] The method includes:

[0034] When the preset humidification start-up conditions are met, the first water valve is opened so that the water in the water storage box flows to the humidification fiber through the water outlet;

[0035] After the first period of time, the fan is started and runs at the target speed to drive the humidified air of the humidifying fiber into the storage room through the air outlet.

[0036] Compared with the prior art, the storage cabinet and its humidification control method disclosed in this invention have the following advantages:

[0037] Beneficial effects:

[0038] A humidification device is installed in the storage cabinet to humidify the storage compartment. The water storage box of the humidification device is located in the compartment partition, and the humidifying fiber is located at the air duct outlet. The water in the water storage box provides moisture to the humidifying fiber by gravity, eliminating the need for a water pump and saving energy consumption. Furthermore, this invention uses one water storage box to achieve the humidification function, which saves the actual space occupied by the humidification device and reduces structural costs compared to the existing technology that uses two water storage boxes.

[0039] In addition, the humidifier and the refrigeration system share a fan. The refrigeration fan brings high-humidity air into the wine cabinet compartment to regulate the humidity of the wine cabinet compartment. The refrigeration fan has a larger air volume, and the way the air flows from top to bottom into the humidifying fibers makes the humidifying fibers moist faster than the way the air is soaked from bottom to top, making the humidifier more effective.

[0040] Furthermore, by designing and controlling the delayed start-up time and operating speed of the fan, it is possible to ensure that the humidifying fibers reach a suitable level of moisture and remain moist without excessive water overflow, thus improving the humidification performance of the humidification device. This invention can significantly reduce the manufacturing cost of the humidification module while enhancing the humidification performance of the humidification device, broadening its application scenarios and making it more convenient for users.

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

They 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, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0057] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0058] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0059] See Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the first structure of a storage cabinet provided in an embodiment of the present invention. Figure 2 This is a second structural schematic diagram of the storage cabinet in an embodiment of the present invention. An embodiment of the present invention provides a storage cabinet 10, including a cabinet body 11, with a cabinet door 111 at the opening of the cabinet body for opening and closing. The cabinet body 11 has a storage compartment 112 inside. It should be noted that the storage cabinet 10 can be applied in various scenarios to store different types of items, such as a wine cabinet, medicine cabinet, merchandise cabinet, or refrigerator, thereby providing a suitable storage environment for different types of items. Specifically, the storage compartment 112 is used to store items. The interior of the storage compartment 112 can be configured with several storage layers, several storage compartments, or other formats according to user needs, without affecting the beneficial effects of the present invention.

[0060] More preferably, the locker 10 further includes a refrigeration system 12, a humidification device 13, a temperature sensor 14, a humidity sensor 15, and a fan 16 connected to the storage compartment 112.

[0061] The refrigeration system 12 provides cooling capacity to the storage compartment 112 to regulate its temperature and maintain it at a low temperature. The refrigeration system 12 can be a compressor refrigeration system, a semiconductor refrigeration system, or another refrigeration method. The output cooling capacity of the refrigeration system 12 can be adjusted according to actual needs. This adjustment is based on the system's load requirements and is determined by considering the ambient temperature, compartment temperature, and humidity levels to control the temperature and humidity of the storage compartment to meet requirements. Specifically, when using compressor refrigeration, the output cooling capacity can be adjusted by changing the compressor's operating speed and / or frequency. When using semiconductor refrigeration, the output cooling capacity can be adjusted by changing the input voltage. Of course, other refrigeration methods can also be used, and the output cooling capacity can be adjusted according to actual conditions, which will not be elaborated upon here.

[0062] See Figure 3This is a schematic diagram of the refrigeration system in an embodiment of the present invention. Taking the use of a compressor for refrigeration as an example, the refrigeration system 12 includes a compressor 121, an evaporator 122, a dryer filter (not shown in the figure), a throttling component 123, a condenser 124, and a gas-liquid separator (not shown in the figure). The working process of the refrigeration system includes a compression process, a condensation process, a throttling process, and an evaporation process. The compression process is as follows: when the refrigerator power cord is plugged in and there is a cooling demand in the refrigerator, the compressor 121 starts working. Low-temperature, low-pressure refrigerant is drawn into the compressor 121 and compressed into high-temperature, high-pressure superheated gas in the cylinder of the compressor 121 before being discharged into the condenser 124. The condensation process is as follows: the high-temperature, high-pressure refrigerant gas dissipates heat through the condenser 124, and the temperature continuously decreases, gradually cooling into room-temperature, high-pressure saturated vapor, and further cooling into saturated liquid. The temperature no longer decreases; this temperature is called the condensation temperature. The pressure of the refrigerant remains almost constant throughout the condensation process. The throttling process is as follows: After condensation, the saturated liquid refrigerant flows into the throttling component 123, such as a capillary tube, after the moisture and impurities are removed by the dryer filter. The refrigerant is throttled and depressurized through the capillary tube, and becomes a room temperature, low pressure wet vapor. The evaporation process is as follows: the room temperature, low pressure wet vapor begins to absorb heat and vaporize in the evaporator 122, which not only lowers the temperature of the evaporator 122 and its surroundings, but also turns the refrigerant into a low temperature, low pressure gas. The refrigerant coming out of the evaporator 122 passes through the gas-liquid separator and returns to the compressor 121. The above process is repeated to transfer the heat inside the refrigerator to the outside air, thus achieving the purpose of refrigeration.

[0063] Of course, the specific forms of refrigeration systems and their refrigeration methods involved in the above scenarios are only examples. In actual applications, they can be set according to the actual situation, and no specific limitations are made here.

[0064] See Figure 4 and Figure 5 , Figure 4 This is a first structural schematic diagram of the humidification device in an embodiment of the present invention. Figure 5 This is a second structural schematic diagram of the humidification device in an embodiment of the present invention. The humidification device 13 is used to adjust the humidity of the storage room 112. Specifically, the humidification device 13 includes a water storage box 131 and a humidifying fiber 132. The humidifying fiber 132 is located below the water storage box 131 and communicates with the water outlet 133 of the water storage box 131. A first water valve 134 is provided at the water outlet 133 of the water storage box. The first water valve 134 is used to control the opening or closing of the water outlet 133 of the water storage box 131. When the first water valve 134 is open, the water outlet 133 is open, and the water in the water storage box 131 flows to the humidifying fiber 132 through the water outlet 133 under the action of gravity. When the first water valve 134 is closed, the water outlet 133 is closed.

[0065] In addition, the humidifying fiber 132 is also located at the air outlet 113 of the storage compartment 112. The fan 16 is a refrigeration fan of the refrigeration system, located above the evaporator area, and is located outside the air outlet 113 of the storage compartment 112. The fan 16 circulates air into the storage compartment 112 through the air outlet 113 to achieve the function of heat dissipation or cooling. At the same time, in this embodiment of the invention, the fan 16 is also reused as a humidifying fan to introduce the humidified air on the humidifying fiber 132 into the storage compartment 112.

[0066] See Figure 2 Temperature sensor 14 is located inside the storage room 112 and is used to collect the current temperature inside the storage room 112. Preferably, temperature sensor 14 includes at least two sub-temperature sensors, and each sub-temperature sensor is located at a different position inside the storage room 112 to collect temperature values ​​at different positions. The average of the temperature values ​​collected by each sub-temperature sensor is taken as the current temperature inside the storage room 112.

[0067] A humidity sensor 15 is installed inside the storage room 112 and is used to collect the current humidity inside the storage room 112. Similarly, the humidity sensor 15 may also include multiple sub-humidity sensors installed in different locations, and the humidity values ​​collected by each sub-humidity sensor are averaged to obtain the current humidity inside the storage room 112.

[0068] Furthermore, the storage cabinet 10 also includes a controller, which is connected to components such as the refrigeration system 12, the humidification device 13, the temperature sensor 14, the humidity sensor 15, and the fan 16, to collect information, perform calculation and analysis, and issue control commands, thereby controlling the operating parameters of the refrigeration system 12 and the starting, running, or stopping status of the humidification device 13 and the fan 16.

[0069] Specifically, see Figure 6 This is a schematic diagram of the first working process of the controller in an embodiment of the present invention. The controller is specifically used to execute steps S11 to S12:

[0070] S11. When the preset humidification start-up conditions are met, control the first water valve to open so that the water in the water storage box flows to the humidification fiber through the water outlet;

[0071] S12. After the first duration, control the fan to start and run at the target speed to drive the humidified air of the humidifying fiber through the air outlet into the storage room.

[0072] In this embodiment of the invention, a humidification start-up condition is preset as the trigger condition for the humidification device 13 to start humidifying the storage room 112.

[0073] Preferably, the preset humidification start condition is: the current room humidity collected by the humidity sensor is less than or equal to a first humidity threshold.

[0074] More preferably, the preset humidification start-up conditions are: the current room humidity collected by the humidity sensor is less than or equal to the first humidity threshold, and the refrigeration system is not running, the cabinet door is not open, and the storage cabinet is not in the defrosting stage.

[0075] When the humidification start-up conditions are met, the first water valve 134 at the outlet of the water storage box 131 in the humidification device 13 is opened. At this time, the outlet 133 of the water storage box 131 is opened, and the water in the water storage box 131 flows through the outlet 133 to the humidifying fiber 132 under the action of gravity. The water permeates into the humidifying fiber 132, wetting it. The time required for the humidifying fiber 132 to reach a suitable humid state is the first duration t1. After the first duration t1, the fan 16 is started. The fan 16 introduces the high-humidity air from the humidifying fiber 132 into the storage compartment 112 through the air outlet 113, thereby increasing the humidity of the compartment and maintaining the humidity within a certain range, ensuring the good storage and preservation effect of the wine cabinet.

[0076] In a preferred embodiment, the first duration is calculated based on the ratio of the preset water absorption of the humidifying fiber to the water flow velocity at the outlet of the water storage box, and the water flow velocity at the outlet of the water storage box is controlled by the opening degree of the first water valve.

[0077] That is, after step S11, the controller is further configured to:

[0078] Obtain the preset water absorption capacity M of the humidifying fiber and the water flow velocity v1 at the outlet of the water storage box;

[0079] The first duration t1 is calculated based on the ratio of the water absorption M to the water flow velocity v1.

[0080] Specifically, when the humidity in the storage compartment is too low, the storage compartment 112 needs to be humidified. When the evaporator in the compartment is not cooling, the cabinet door is not open, and it is not in the defrosting stage, the first water valve is opened, and after the first time period t1, the fan 16 is started to work for a certain period of time to blow the high humidity air on the humidifying fibers into the storage compartment 112, thereby increasing the humidity of the compartment and maintaining the humidity of the compartment within a certain range to ensure the good storage and preservation effect of the wine cabinet.

[0081] Assuming that the water flow velocity at the outlet of the water storage box 131 is v1 under the control of the opening degree of the first water valve, and the water absorption of the humidifying fiber 132 is M when the humidifying fiber 132 is in a suitable humid state, after the first water valve 134 is opened for a period of time, t1 = M / v1, the fan 16 is then started, so as to ensure that the humidifying fiber is in a suitable humid state when the fan 16 is started.

[0082] As a preferred embodiment, the target rotation speed setting needs to satisfy the following: when the fan 16 operates at the target rotation speed, the water flow rate injected into the humidifying fiber is consistent with the water consumption rate of the fan consuming water from the humidifying fiber, thereby ensuring that the humidifying fiber can always maintain a moist state without the problem of excessive water overflow.

[0083] That is, after step S11, the controller is further configured to:

[0084] Obtain the water flow velocity at the outlet of the water storage box;

[0085] The water consumption rate of the humidifying fiber is determined based on the water flow rate; the water consumption rate of the humidifying fiber is consistent with the water flow rate at the outlet of the water storage box.

[0086] The target rotational speed of the fan is calculated based on the water consumption rate of the humidifying fiber; the target rotational speed is positively correlated with the water consumption rate of the humidifying fiber.

[0087] Specifically, let the water flow velocity at the outlet of the water storage box be v1. When the rotational speed of the fan 16 is v2, the water consumption rate on the humidifying fiber is v3, where v3 = kv2, and k is a constant. To ensure that the humidifying fiber remains moist without overflowing, the water injection rate onto the humidifying fiber needs to be consistent with the water consumption rate of the fan, i.e., v1 = v3. Therefore, v1 = v3 = kv2. Thus, the target rotational speed of the fan 16 can be calculated based on the water flow velocity v1, and the fan 16 can be controlled to operate at the target rotational speed.

[0088] In a preferred embodiment, after step S12, the controller is further configured to execute step S13:

[0089] S13. When the preset humidification stop condition is met, control the first water valve and the fan to shut down.

[0090] In this embodiment of the invention, a humidification stop condition is preset as a trigger condition for the humidification device 13 to stop humidifying the storage room 112.

[0091] Preferably, the preset humidification stop condition is: the current room temperature collected by the humidity sensor is greater than or equal to the second humidity threshold.

[0092] It should be noted that the range formed by the first humidity threshold and the second humidity threshold is the optimal storage humidity range for the locker. The specific values ​​of the first humidity threshold and the second humidity threshold can be set according to the actual situation, and are not specifically limited here.

[0093] The technical means employed in the embodiments of the present invention have the following beneficial effects:

[0094] A humidification device is installed in the storage cabinet to humidify the storage compartment. The water storage box of the humidification device is located in the compartment partition, and the humidifying fiber is located at the air duct outlet. The water in the water storage box provides moisture to the humidifying fiber by gravity, eliminating the need for a water pump and saving energy consumption. Furthermore, this invention uses one water storage box to achieve the humidification function, which saves the actual space occupied by the humidification device and reduces structural costs compared to the existing technology that uses two water storage boxes.

[0095] In addition, the humidifier and the refrigeration system share a fan. The refrigeration fan brings high-humidity air into the wine cabinet compartment to regulate the humidity of the wine cabinet compartment. The refrigeration fan has a larger air volume, and the way the air flows from top to bottom into the humidifying fibers makes the humidifying fibers moist faster than the way the air is soaked from bottom to top, making the humidifier more effective.

[0096] Furthermore, by designing and controlling the delayed start-up time and operating speed of the fan, it is possible to ensure that the humidifying fibers reach a suitable level of moisture and remain moist without excessive water overflow, thus improving the humidification performance of the humidification device. This invention can significantly reduce the manufacturing cost of the humidification module while enhancing the humidification performance of the humidification device, broadening its application scenarios and making it more convenient for users.

[0097] In a preferred embodiment, the water storage box 131 is disposed in the compartment partition 114 at the top of the storage room, see [reference]. Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of the first structure of the compartment partition in an embodiment of the present invention. Figure 8 This is a second structural schematic diagram of the compartment partition in an embodiment of the present invention. The compartment partition 114 is composed of an upper part 1141 and a lower part 1142. A water storage box 131, heat insulation foam 1143 and reinforcing iron 1144 are provided inside the compartment partition 114. The heat insulation foam 1143 is used to reduce heat exchange between compartments, and the reinforcing iron 1144 is used to enhance the structural strength of the partition.

[0098] See Figure 9 and Figure 10 , Figure 9This is a schematic diagram of the first structure of the water storage box in an embodiment of the present invention. Figure 10 This is a second structural schematic diagram of the water storage box in an embodiment of the present invention. A water storage box 131 is provided within the compartment partition for storing supplementary water for the humidifying fiber 132. The water storage box 131 includes a body 1311 and a cover 1312. The body 1311 stores water, and the cover 1312 is located at the upper opening of the body 1311. A water outlet 133 is provided at the lower part of the water storage box 131, and a first water valve 134 is provided at the outlet 133. When the humidifying fiber 132 needs additional water, the first water valve 134 opens, and water from the water storage box 131 flows out from the outlet.

[0099] The water storage box is also equipped with a water inlet 135 and an external water pipe 136. The water inlet 135 of the water storage box is connected to an external water source through the external water pipe 136. A second water valve (not shown in the figure) is provided at the water inlet 135, which is used to control the opening or closing of the water inlet 135 of the water storage box 131. When the water in the water storage box is consumed, water needs to be replenished through the water inlet 135. Water can be added to the water storage box 131 by controlling the external water source to inject water into the water storage box 131 through the external water pipe 136 and the water inlet 135, or by the user manually adding water.

[0100] The locker also includes a liquid level sensor 17, which is located at the liquid level of the target water volume in the water storage box 131 and is used to send a full water signal when the water volume in the water storage box 131 reaches the target water volume.

[0101] See Figure 11 This is a third structural schematic diagram of the humidification device in an embodiment of the present invention. The water outlet 133 of the water storage box is connected to the humidifying fiber 132 through a funnel structure 137. The water outlet 133 of the water storage box is located at the top opening of the funnel structure 137, and the humidifying fiber 132 is connected to the bottom opening 1371 of the funnel structure 137.

[0102] When the storage room 112 needs humidification, the first water valve 134 is opened. Water in the water storage box 131 flows into the funnel structure 137 below the water valve under the drive of gravity. The lower part of the funnel structure 137 is embedded with the humidifying fiber 132. When water flows into the funnel structure 137 from the outlet 133, it is guided by the funnel structure and gathers at the lower part of the funnel structure 137 and comes into contact with the humidifying fiber 132, so that the water penetrates into the humidifying fiber 132. Then, the fan 16 drives the high humidity air on the humidifying fiber 132 into the storage room 112 to achieve the purpose of humidifying the storage room.

[0103] See Figure 12 and Figure 13 , Figure 12 This is a schematic diagram of the third structure of the storage cabinet in an embodiment of the present invention. Figure 13 This is a fourth structural schematic diagram of the storage cabinet in this embodiment of the invention. In this embodiment, the cabinet interior is divided into several storage compartments 112 by several partitions 114. Each storage compartment is equipped with an independent evaporator and a cooling fan, and each storage compartment has a humidifying fiber 132 at its air outlet. A water storage box 131 can be located in the top partition, and water is injected into the humidifying fibers at the air outlets of each storage compartment through one water storage box 131, thereby humidifying each storage compartment simultaneously. More preferably, a water storage box is provided in the partition above each storage compartment, and each water storage box injects water into the humidifying fibers at the air outlet of its respective storage compartment, realizing independent humidification control of each storage compartment.

[0104] Each storage compartment has a fan 16 inside the back panel to drive airflow. The fan 16 is fixed to the back panel. The fan cover 161 and the guide baffle 162 around the fan form an air cavity. When the fan 16 is working, it guides the air through the air outlet 113 into the storage compartment.

[0105] In a preferred embodiment, the controller is further configured to:

[0106] Calculate the cumulative open duration of the first water valve;

[0107] When the cumulative open time of the first water valve is greater than or equal to the second time, the second water valve is controlled to open so that the external water source fills the water storage box, and the cumulative open time is reset to zero; wherein, the second time is calculated based on the ratio of the target water storage capacity of the water storage box to the water flow velocity at the outlet of the water storage box.

[0108] When a full water signal is received from the liquid level sensor, the second water valve is controlled to close.

[0109] Specifically, in this embodiment of the invention, when the first water valve 134 is opened, the opening time of the first water valve 134 is timed, and water in the water storage box 131 continuously flows to the humidifying fiber 132. After a period of time, the water in the water storage box 131 will be consumed. When the cumulative opening time of the first water valve 134 reaches a second duration, it is determined that there is a shortage of water in the water storage box. Then, the second water valve is opened, and external water enters the water storage box 131 through the external water pipe 136 and the water inlet 135. At the same time, the currently recorded cumulative opening time of the first water valve is reset to zero.

[0110] The second duration t2 is calculated based on the target water storage capacity N of the water storage box and the water flow velocity v1: t2 = N / v1. The water flow velocity v1 is controlled by the opening degree of the first water valve 134, and the target water storage capacity N is less than or equal to the maximum volume of the water storage box 131.

[0111] During the process of filling the water storage box 131 with water from an external water source, when the water level rises to the liquid level height corresponding to the target water storage volume N, the liquid level sensor 17 sends a full water signal, which determines that the water storage box 131 is full, controls the second water valve to close, and stops filling the water storage box.

[0112] In a preferred embodiment, the controller is further configured to:

[0113] When the preset cooling start-up conditions are met, the refrigeration system and fan 16 are controlled to start operation;

[0114] When the preset cooling stop conditions are met, the cooling system and fan 16 are controlled to stop operating.

[0115] The cooling start condition is that the current room temperature collected by the temperature sensor 14 is greater than or equal to a first temperature threshold; the cooling stop condition is that the current room temperature collected by the temperature sensor 14 is less than or equal to a second temperature threshold.

[0116] It should be noted that the range formed by the first temperature threshold and the second temperature threshold is the optimal storage temperature range of the locker. The specific values ​​of the first temperature threshold and the second temperature threshold can be set according to the actual situation, and are not specifically limited here.

[0117] Specifically, see Figure 14 This is a schematic diagram of the second working process of the controller in an embodiment of the present invention. The water injection control, humidification control, and refrigeration logic of the humidification device in the storage cabinet are as follows:

[0118] When the locker is first powered on, the second water valve opens to fill the water tank. When the water level sensor on the tank detects a full water signal, the external water valve closes, stopping the water filling. During operation, temperature and humidity sensors inside the locker monitor the temperature and humidity. When the temperature inside the locker exceeds the first temperature threshold, the compressor starts, and the fan blows cool air from the evaporator into the locker to regulate the temperature. Once the temperature drops to the second temperature threshold, the compressor and fan stop operating.

[0119] When the humidity in the storage compartment is detected to be below the first humidity threshold, if the compressor is not running and the cabinet door is not open or in the defrosting stage, the first water valve of the water storage box opens, and the opening time of the first water valve in the water storage box is recorded. Water in the water storage box slowly flows out to the humidifying fiber, which begins to absorb water and become moist. When the humidifying fiber has absorbed water to a suitable humidity level, that is, after the first time interval, the fan starts, blowing the high-humidity air from the humidifying fiber into the compartment to regulate the humidity. When the humidity in the compartment reaches the second humidity threshold, the first water valve of the water storage box closes, and the closing time of the first water valve is recorded, the cumulative opening time is calculated, and the fan stops working. If the humidity in the storage compartment is detected to be below the second humidity threshold while the compressor is running, the above humidification process will run after the compressor stops working. The same applies when the cabinet door is open and during the defrosting stage.

[0120] As the humidifier operates, the water stored in the water tank will be consumed. When the cumulative opening time of the first water valve reaches the second time, it is determined that there is no water in the water tank. The second water valve opens to inject water into the water tank. When the liquid level sensor on the water tank detects a full water signal, the second water valve closes and stops injecting water.

[0121] When the temperature sensor detects that the temperature inside the storage compartment is higher than the first temperature threshold, the compressor starts, the storage cabinet's cooling system starts, and the fan drives the cool air from the evaporator into the storage compartment to regulate the temperature. When the temperature sensor detects that the temperature inside the storage compartment is lower than the second temperature threshold, the compressor and fan stop working.

[0122] Using the technical means of this invention, a humidification device is installed in the storage cabinet to achieve the function of humidifying the storage compartment. The humidification device can simultaneously handle both automatic external water filling and manual internal water filling by the user. The humidification device is installed above the compartment, with the water storage box of the humidification device located in the compartment partition. The humidifying fiber is located at the air duct outlet. The water in the storage box provides moisture to the humidifying fiber through gravity. The humidification system and the refrigeration system share a fan, which brings high-humidity air into the wine cabinet compartment through the refrigeration fan to achieve the purpose of regulating the humidity of the wine cabinet compartment. In order to reliably control the water filling process of the storage box, a liquid level sensor is used on the storage box to monitor the water level. Combined with water filling time control, this effectively ensures the normal operation of the humidification device's water filling system. While effectively regulating the humidity in the compartment, this invention broadens the application scenarios of the humidification device, makes it more convenient for users, and greatly reduces the manufacturing cost of the humidification module.
