[0022] The target opening area corresponding to the current water level height interval is determined as the target opening area of the first water valve according to the correspondence between the preset water level height interval and the target opening area.

[0023] Wherein, in the correspondence between the water level height interval and the target opening area, the target opening area is calculated according to the target water flow speed and the average water level height of the water level height interval.

[0032] The controller is also used for:

[0033] After the first water valve is opened, record the continuous working time of the first water valve;

[0034] When the continuous working time is greater than or equal to the first time, the humidifying fan is controlled 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;

[0035] The first duration is calculated based on the ratio of the preset water absorption capacity of the humidifying fiber to the target water flow velocity; the target rotation speed is positively correlated with the target water flow velocity.

[0036] 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;

[0037] 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.

[0042] Record the cumulative open duration of the first water valve from the moment the water storage box is full;

[0043] When the cumulative opening 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 can inject water into the water storage box;

[0044] When the water storage box is full, the second water valve is closed 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 target water flow rate.

[0045] 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.

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.

[0071] 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.

[0072] 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, and storage compartments 112 inside the cabinet body 11. Optionally, a plurality of storage compartments 112 are formed within the cabinet body 11 by partitions 114.

[0073] 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.

[0074] More preferably, the locker 10 further includes a refrigeration system 12, a humidification system 13, a temperature sensor 14, and a humidity sensor 15 connected to the storage compartment 112.

[0075] 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-based system, a semiconductor-based 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 ensure the storage compartment's temperature and humidity meet requirements. Specifically, when using a compressor-based system, the output cooling capacity can be adjusted by changing the compressor's operating speed and / or frequency. When using a semiconductor-based system, 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.

[0076] 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.

[0077] 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.

[0078] See Figure 4 This is a first structural schematic diagram of the humidification system in an embodiment of the present invention. The humidification system 13 is used to regulate the humidity of the storage room 112. Specifically, the humidification system 13 includes a water storage box 131 and a humidifying fiber 132. The humidifying fiber 132 is located at the air outlet 113 of the storage room 112 to provide humidified air to the storage room 112. 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.

[0079] See Figure 5This is a schematic diagram of the first structure of the water storage box in an embodiment of the present invention. The water storage box 131 has a certain height, that is, the maximum water storage height of the water storage box is L. The first water valve 134 is located at the bottom outlet of the water storage box. The opening area S of the first water valve 134 is adjustable, so that the area of ​​the outlet 133 of the water storage box can be controlled by controlling the opening area of ​​the first water valve 134, thereby adjusting the water flow speed v1 flowing out from the first water valve 134.

[0080] 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.

[0081] 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.

[0082] Furthermore, the storage cabinet 10 also includes a controller, which is connected to components such as the refrigeration system 12, the humidification system 13, the temperature sensor 14, and the humidity sensor 15 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 system 13.

[0083] 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:

[0084] 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;

[0085] S12. During the opening of the first water valve, the opening area of ​​the first water valve is adjusted in real time so that the water flow rate of the first water valve is consistent with the preset target water flow rate.

[0086] In this embodiment of the invention, a humidification start-up condition is preset as the trigger condition for the humidification system 13 to start humidifying the storage room 112.

[0087] Preferably, the preset humidification start condition is: the current room humidity collected by the humidity sensor 15 is less than or equal to a first humidity threshold.

[0088] More preferably, the preset humidification start-up conditions are: the current room humidity collected by the humidity sensor 15 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.

[0089] 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 system 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 to the humidifying fiber 132 through the outlet 133 under the action of gravity. The water penetrates into the humidifying fiber 132 and wets the humidifying fiber 132.

[0090] Because the water in the water storage box is driven by gravity, the water flow rate of the first water valve 134 is directly related to the water level in the water storage box 131. The higher the water level in the water storage box 131, the faster the water flow rate of the first water valve, and vice versa. If the height of the water storage box itself is small, the difference will not be too obvious. However, when the height of the water storage box itself is large, due to the influence of gravity, there will be a large difference in water pressure at the first water valve 134 at high and low water levels. The water flow rate of the first water valve 134 will also be large, and the amount of water injected into the humidifying fiber per unit time will also be different. Since the rate at which the humidifying fiber 132 consumes water is usually relatively constant, it is possible that when the water level is too low, the water flow rate of the first water valve 134 is too slow, causing the humidifying fiber to dry out, or when the water level is high, the water flow rate of the first water valve 134 is too fast, causing the humidifying fiber to overflow due to excessive water.

[0091] To more accurately control the water injection volume into the humidifying fibers, this embodiment of the invention uses a first water valve with an adjustable flow rate, i.e., an adjustable opening area. During the opening of the first water valve 134, the opening area of ​​the first water valve 134 is adjusted in real time according to the water level in the water storage box 131, thereby adjusting the water flow rate from the first water valve 134 to the humidifying fibers 132, so that the water flow rate v1 of the first water valve is close to the preset target water flow rate v. s Consistency ensures that the amount of water injected into the humidifying fiber 132 per unit time will not vary significantly due to changes in the water level in the water storage box.

[0092] By employing the technical means of this invention, a humidification system is installed in the storage cabinet to achieve the humidification function of the storage compartment. The humidifying fiber is located at the air duct outlet, and water in the water storage box provides moisture to the humidifying fiber through gravity, eliminating the need for a water pump, thus saving energy consumption and reducing the actual space occupied by the humidification system, thereby saving structural costs. By using a first water valve with an adjustable opening area to control the time and amount of water injected into the humidifying fiber from the water storage box, the humidification performance is improved. This ensures that the amount of water injected into the humidifying fiber per unit time does not vary significantly due to changes in the water level in the water storage box. This guarantees that the humidifying fiber reaches a suitable humidification state and remains humid without overflowing.

[0093] Furthermore, this embodiment of the invention is implemented based on the above embodiment, and the means of adjusting the opening area of ​​the first water valve 134 is optimized.

[0094] In the first preferred embodiment, the water level in the water storage box is monitored by a water level sensor 17. That is, the storage cabinet also includes a water level sensor 17, which is located in the water storage box 131 and used to monitor the current water level H in the water storage box 131. Then step S12 includes steps S121 to S123:

[0095] S121. During the opening of the first water valve, the current water level height of the water storage box monitored by the water level sensor is obtained in real time.

[0096] S122. Calculate the target opening area of ​​the first water valve based on the preset target water flow velocity and the current water level.

[0097] S123. Adjust the current opening area of ​​the first water valve according to the target opening area.

[0098] Specifically, during the opening of the first water valve 134, the current water level height H of the water storage box 131 is collected in real time, and the water level is determined based on the current water level height H and the preset target water flow velocity v. s Calculate the target opening area of ​​the first water valve 134, such that after controlling the opening degree of the first water valve according to the target opening area, the water flow velocity v1 of the first water valve 134 is equal to or approaches the target water flow velocity v. s .

[0099] Preferably, in this embodiment of the invention, the opening area of ​​the first water valve 134 can be adjusted in real time. Step S122 specifically includes:

[0100] Based on the preset target water flow velocity and the water level, the target opening area of ​​the first water valve is calculated using the following formula:

[0101]

[0102] Among them, v s The target water flow velocity is H, the current water level is r, and the preset first correction constant is r.

[0103] That is, by collecting the current water level in real time and calculating the target opening area S using the above formula, the higher the current water level, the smaller the opening area of ​​the first water valve. This allows for real-time control of the opening area of ​​the first water valve 134, ensuring that as the water level in the water storage box 131 gradually decreases, the opening area of ​​the first water valve 134 gradually increases, thus maintaining a stable water flow rate.

[0104] By employing the technical means of this invention, the target opening area is calculated in real time by collecting the current water level, thereby enabling real-time adjustment of the opening area of ​​the first water valve. This ensures that the water flow velocity remains stable to the greatest extent possible, preventing significant differences in the amount of water injected into the humidifying fiber per unit time due to changes in the water level in the storage box. This ensures that the humidifying fiber reaches a suitable humidification state and remains continuously moist without causing excessive water overflow, thus improving the humidification performance of the humidification system.

[0105] Preferably, in this embodiment of the invention, the opening area of ​​the first water valve 134 can also be adjusted in a stepped manner. Step S122 specifically includes:

[0106] Determine the water level range in which the current water level is located; wherein the water level range is pre-divided;

[0107] Based on the preset correspondence between water level height range and target opening area, the target opening area corresponding to the current water level height range is determined and used as the target opening area of ​​the first water valve.

[0108] In the correspondence between the water level height range and the target opening area, the target opening area is calculated based on the target water flow velocity and the average water level height of the water level height range.

[0109] Specifically, the maximum water storage height L of the water storage box is first divided into several water level intervals from high to low: L1, L2, L3...Ln. The average water level H corresponding to each interval is pre-defined. n and the target water flow velocity v s To calculate the target opening area S of each interval n :

[0110]

[0111] Among them, the average water level height H n It is the average of the upper limit and lower limit of the water level height within the water level height range.

[0112] This establishes a correspondence between the water level height range Ln and the target opening area Sn. During application, the current water level is collected in real time, its corresponding water level range is determined, the corresponding target opening area is obtained by finding the correspondence, and the current opening area of ​​the first water valve 134 is adjusted.

[0113] By employing the technical means of this invention, a correspondence between water level height ranges and target opening areas is pre-established. Based on changes in the current water level height, the opening area of ​​the first water valve is adjusted in a stepwise manner. This ensures that the water flow velocity remains relatively stable, preventing significant differences in the amount of water injected into the humidifying fiber per unit time due to changes in the water level in the storage box. Simultaneously, it reduces data calculations, decreases the number of adjustments to the first water valve, and improves the service life of the humidification system.

[0114] In the second preferred embodiment, the water level in the storage tank is indirectly monitored by recording the opening time of the first water valve; that is, the controller is also used for:

[0115] Record the cumulative open duration of the first water valve from the moment the water storage box is full;

[0116] Step S12 specifically includes steps S124 and S125:

[0117] S124. During the opening process of the first water valve, the target opening area of ​​the first water valve is calculated using the following formula based on the preset target water flow velocity and the cumulative opening time:

[0118] S = v s ×t×b;

[0119] Among them, v s The target water flow velocity is t, the cumulative opening time is b, and the preset second correction constant is b.

[0120] S125. Adjust the current opening area of ​​the first water valve according to the target opening area.

[0121] Specifically, the locker also includes a timer to record the cumulative operating time t of the first water valve from the moment the water tank is full. The controller acquires the cumulative operating time t of the first water valve recorded by the timer in real time, and calculates the target opening area S in real time using the above formula. The longer the cumulative operating time of the first water valve, the less water remains in the water tank, the lower the current water level, and the larger the target opening area of ​​the first water valve. This allows for real-time control of the opening area of ​​the first water valve 134, ensuring that as the water level in the water tank 131 gradually decreases, the opening area of ​​the first water valve 134 gradually increases, thus maintaining a stable water flow rate.

[0122] It should be noted that the cumulative working time t is calculated from the moment the water tank is full. In practical applications, when the water tank is low on water, it needs to be replenished. Therefore, the moment the replenishment action ends can be considered the moment the water tank is full. Each time the replenishment action ends, the cumulative working time is reset to zero and the timing restarts. Alternatively, a water level sensor can be installed in the water tank to monitor its fullness, which will not be elaborated upon here.

[0123] By employing the technical means of this invention, the current water level of the water storage box is indirectly monitored by real-time monitoring of the cumulative opening time of the first water valve. The target opening area is then calculated in real-time, enabling real-time adjustment of the opening area of ​​the first water valve. This maximizes the stability of the water flow rate, ensuring that the amount of water injected into the humidifying fiber per unit time does not vary significantly due to changes in the water level in the storage box. This ensures the humidifying fiber reaches a suitable humidification state and remains consistently moist without excessive water overflow, thus improving the humidification performance of the humidification system.

[0124] See Figure 7 This is a second structural schematic diagram of the humidification system in an embodiment of the present invention. The storage cabinet 10 also includes a humidifying fan 16. The humidifying fan 16 is located outside the air outlet 113 of the storage room 112. The humidifying fan 16 is used to introduce the humidified air on the humidifying fiber 132 into the storage room 112 through the air outlet 113 when it is started.

[0125] Preferably, in this embodiment of the invention, the refrigeration fan located above the evaporator area in the refrigeration system is reused as a humidifying fan 16. When used as a refrigeration fan, it circulates air to the interior of the storage room 112 through the air outlet 113 to achieve the function of heat dissipation or cooling.

[0126] The controller is also used to perform steps S13 and S14:

[0127] S13. After controlling the first water valve to open, record the continuous working time of the first water valve;

[0128] S14. When the continuous working time is greater than or equal to the first duration, the humidifying fan is controlled to start and run at the target speed to drive the humidifying air of the humidifying fiber through the air outlet into the storage room; wherein, the first duration is calculated based on the ratio of the preset water absorption of the humidifying fiber to the target water flow velocity; the target speed is positively correlated with the target water flow velocity.

[0129] In this embodiment of the invention, the time required for the humidifying fiber 132 to permeate to a suitable humid state is first calculated as a first duration t1. The first duration t1 is calculated based on the ratio of the preset water absorption capacity M of the humidifying fiber to the water flow velocity v1 of the first water valve. By adjusting the opening area of ​​the first water valve in real time, the water flow velocity of the first water valve is made to approach the target water flow velocity v1. s Therefore, it can be determined based on the target water flow velocity v. s The first duration t1 is calculated. A timer is used to monitor the continuous working time of the first water valve from opening to closing. After the first duration t1, the humidifying fan 16 is started. The humidifying fan 16 introduces the high humidity air on 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 of the compartment within a certain range, ensuring the good storage and preservation effect of the wine cabinet.

[0130] 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 humidifying fan 16 is started to work for a certain period of time and 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.

[0131] Assuming that the water flow velocity v1 at the outlet of the water storage box 131 is maintained at the target water flow velocity v under the control of the opening degree of the first water valve. s When the humidifying fiber 132 is in a suitable humidified state, the water absorption capacity of the humidifying fiber 132 is M. After the first water valve 134 is opened for a period of time, t1 = M / v s Then, start the humidifying fan 16 to ensure that the humidifying fibers are in a suitable humidified state when the humidifying fan 16 is started.

[0132] Preferably, the target rotation speed setting needs to satisfy the following: when the humidifying 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 humidifying 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.

[0133] That is, after step S13, the controller is further configured to:

[0134] The water consumption rate of the humidifying fiber is determined based on the target 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;

[0135] The target rotational speed of the humidifying 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.

[0136] Specifically, let the water flow velocity v1 at the outlet of the water storage box 131 be maintained at the target water flow velocity v s When the rotational speed of the humidifying 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 set to match the water consumption rate of the humidifying fan, i.e., v3 = kv2. s =v3. Then v s =v3=kv2, therefore, based on the target water flow velocity v s The target speed of the humidifying fan 16 is calculated, and the humidifying fan 16 is controlled to operate at the target speed.

[0137] In a preferred embodiment, after step S14, the controller is further configured to execute step S15:

[0138] S15. When the preset humidification stop condition is met, control the first water valve and the humidification fan to shut down.

[0139] In this embodiment of the invention, a humidification stop condition is preset as a trigger condition for the humidification system 13 to stop humidifying the storage room 112.

[0140] Preferably, the preset humidification stop condition is: the current room temperature collected by the humidity sensor 15 is greater than or equal to the second humidity threshold.

[0141] 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.

[0142] The technical means employed in the embodiments of the present invention have the following beneficial effects:

[0143] A humidification system is installed in the storage cabinet to humidify the storage compartment. The water storage box of the humidification system 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 system and reduces structural costs compared to the existing technology that uses two water storage boxes.

[0144] Furthermore, by designing and controlling the water flow rate of the first water valve, the delayed start time of the humidifying fan, and the operating speed of the humidifying fan, the water filling process of the water storage box can be reliably controlled, ensuring that the humidifying fibers reach a suitable level of moisture and remain moist without overflowing due to excessive water, thus improving the humidification performance of the humidification system. This invention can significantly reduce the manufacturing cost of the humidification module while enhancing the humidification performance of the humidification system, broadening its application scenarios and making it more convenient for users.

[0145] In addition, the humidification system shares a fan with the refrigeration system. The humidification fan brings high-humidity air into the wine cabinet compartment to regulate the humidity of the compartment. The humidification fan has a larger air volume, and the downward flow of air into the humidification fibers makes the fibers humidified faster than the upward saturation method, thus making the humidification capacity of the humidification system stronger.

[0146] 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 8 and Figure 9 , Figure 8 This is a schematic diagram of the first structure of the compartment partition in an embodiment of the present invention. Figure 9 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.

[0147] See Figure 10 and Figure 11 , Figure 10 This is a schematic diagram of the second structure of the water storage box in an embodiment of the present invention. Figure 11This is a third 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.

[0148] 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.

[0149] See Figure 12 This is a schematic diagram of the third structure of the humidification system 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.

[0150] 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 humidifying 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.

[0151] See Figure 13 and Figure 14 , Figure 13 This is a schematic diagram of the third structure of the storage cabinet in an embodiment of the present invention. Figure 14This 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 (i.e., a humidifying fan). Humidifying fibers 132 are provided at the air outlet of each storage compartment. A water storage box 131 can be located in the top partition, and water is injected into the humidifying fibers at the air outlet 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.

[0152] Each storage compartment has a humidifying fan 16 on its back panel to drive airflow. The humidifying fan 16 is fixed to the back panel. The fan cover 161 and the guide baffle 162 around the humidifying fan form an air cavity. When the humidifying fan 16 is working, it guides air through the air outlet 113 into the storage compartment.

[0153] In a preferred embodiment, the controller is further configured to:

[0154] Record the cumulative open duration of the first water valve from the moment the water storage box is full;

[0155] When the cumulative opening 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 can inject water into the water storage box;

[0156] When the water storage box is full, the second water valve is closed 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 target water flow rate.

[0157] 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.

[0158] 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, ensuring the target water flow velocity v1 in the designated area. s The target water storage capacity N is less than or equal to the maximum volume of water storage box 131.

[0159] In this embodiment of the invention, the fullness of the water storage box can be determined by the water flow rate of the second water valve, the opening duration, and the target water storage capacity of the storage box, thereby controlling the second water valve to close and stop water injection into the storage box. Alternatively, a water level sensor 17 can be installed in the storage box to detect the current water level. During the process of external water supply to the storage box 131, when the water level rises to the height corresponding to the target water storage capacity N, the water level sensor 17 sends a full water signal, indicating that the storage box 131 is full, and controlling the second water valve to close and stop water injection into the storage box.

[0160] In a preferred embodiment, the controller is further configured to:

[0161] When the preset cooling start-up conditions are met, the refrigeration system and humidifier fan 16 are controlled to start operation;

[0162] When the preset cooling stop conditions are met, the cooling system and humidifying fan 16 are controlled to stop operating.

[0163] 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.

[0164] 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.

[0165] Specifically, see Figure 15 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 system and the refrigeration system in the storage cabinet are as follows:

[0166] When the locker is first powered on, the second water valve opens to fill the water tank. When the water level sensor 17 on the water tank detects a full water signal, the external water valve closes, stopping the water filling. During the locker's operation, temperature and humidity sensors inside the storage compartment monitor the temperature and humidity. When the temperature in the storage compartment exceeds the first temperature threshold, the compressor starts, and the cooling fan starts to blow cold air from the evaporator into the storage compartment to regulate the temperature. Once the temperature drops to the second temperature threshold, the compressor and cooling fan stop operating.

[0167] 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 tank opens, and the opening time of the first water valve in the water tank is recorded. Water slowly flows out of the water tank to the humidifying fibers, which begin to absorb water and become moist. When the humidifying fibers have absorbed water to a suitable moisture level, that is, after the first time interval, the humidifying fan starts, blowing the high-humidity air from the humidifying fibers into the compartment to regulate the humidity. Once the humidity in the compartment reaches the second humidity threshold, the first water valve of the water tank closes, and the closing time of the first water valve is recorded, the cumulative opening time is calculated, and the humidifying fan stops working. If the compressor is running when the humidity in the storage compartment is detected to be below the second humidity threshold, 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.

[0168] As the humidification system 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 water level sensor on the water tank detects a full water signal, the second water valve closes and stops injecting water.

[0169] 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 humidifying fan draws 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 humidifying fan stop working.

[0170] Using the technical means of this invention, a humidification system is installed in the storage cabinet to achieve the function of humidifying the storage compartment. The humidification system can simultaneously handle both automatic external water filling and manual internal water filling by the user. The humidification system is installed above the compartment, with the water storage box of the humidification system located in the compartment partition, and the humidifying fiber located at the air duct outlet. Water in the storage box provides moisture to the humidifying fiber through gravity. The humidification system shares a fan with the refrigeration system, bringing high-humidity air into the wine cabinet compartment through the humidifying fan to achieve the purpose of regulating the humidity of the wine cabinet compartment. To reliably control the water filling process of the storage box, a water level sensor is used on the storage box to monitor the water level, combined with water filling time control, effectively ensuring the normal operation of the humidification system's water filling system. While effectively regulating the humidity in the compartment, this system broadens its application scenarios, makes it more convenient for users, and significantly reduces the manufacturing cost of the humidification module.

[0194] Among them, v s The target water flow velocity is t, the cumulative opening time is b, and the preset second correction constant is b.
