[0062] refer to Figure 1 and Figure 2 In some embodiments, the storage box includes a first compartment 11, a first evaporator 21, a first housing 31, a second housing 32, and a second evaporator 22.

[0063] The first room 11 forms a space for storing items.

[0064] The first evaporator 21 is configured to exchange heat with air to generate condensate.

[0065] The first housing 31 is configured to receive condensate generated by the first evaporator 21.

[0066] The second box 32 is operatively connected to the first box 31.

[0067] The second evaporator 22 is disposed inside the second housing 32 and is configured to exchange heat with the condensate inside the second housing 32.

[0068] The condensate in the second housing 32 is configured to regulate at least one of the temperature and humidity in the first chamber 11.

[0069] In the above embodiment, the first evaporator 21 exchanges heat with the outside air, causing water vapor in the air to condense into liquid water, thus achieving an automatic water production function. The first box 31 is located below the first evaporator 21 and is used to receive and collect the condensate produced by the first evaporator 21. The second box 32 is operably connected to the first box 31 through a communication structure, allowing the condensate in the first box 31 to flow into the second box 32. The second evaporator 22 is located inside the second box 32 and exchanges heat with the condensate inside the second box 32, using the condensate in the second box 32 to regulate the temperature and / or humidity inside the first chamber 11.

[0070] According to the description of the above embodiments, the storage tank can achieve continuous automatic water production and collection without the need for external water supply, and can dynamically regulate the environment in the first chamber 11 based on the collected condensate. Since water has a large specific heat capacity, it can effectively store and transfer heat. Therefore, using condensate to dynamically regulate the environment in the first chamber 11 can alleviate the problem of large temperature and humidity fluctuations in the chamber, improve the constant temperature and humidity effect in the chamber, and thus improve the stability and reliability of the preservation of items in the storage space.

[0071] In some embodiments, the storage box further includes a third housing 33, which is located below the first housing 31. The first housing 31 is equipped with a switch valve. The third housing 33 is arranged side by side with the second housing 32 and is in communication with the second housing 32. When there is a large amount of condensate in the first housing 31, the switch valve is opened to allow the condensate in the first housing 31 to enter the third housing 33, and then flow into the second housing 32 through the third housing 33.

[0072] refer to Figure 1 and Figure 3 In some embodiments, the storage box further includes a humidification assembly 4, which includes a spray element 41 and a humidification port 42. The spray element 41 is disposed within the second housing 32 and configured to spray using a portion of the condensate within the second housing 32, thereby forming an atomized airflow. The humidification port 42 is configured to connect the second housing 32 and the first chamber 11 to direct the atomized airflow generated by the spray element 41 to the first chamber 11.

[0073] In the above embodiment, the spray element 41 is located inside the second box 32. It can pressurize some of the condensate in the second box 32, break the condensate into micron-sized droplets, and spray it under high pressure to form a fine atomized airflow. The atomized airflow enters the first chamber 11 through the humidification port 42, realizing rapid adjustment of the humidity in the storage space. Combined with the automatic water production function of the first evaporator 21 and the water collection and transfer function of the first box 31 and the second box 32, the entire system can continuously complete the process of water production, water storage, atomization and humidification without an external water source. Therefore, it can further enhance the humidity control capability of the first chamber 11, which is conducive to achieving a stable and continuous constant temperature and humidity environment and improving the storage performance of the storage box for temperature and humidity sensitive items.

[0074] In some embodiments, one humidification port 42 may be provided, or two or more humidification ports 42 may be provided as needed.

[0075] In some embodiments, the spray element 41 is disposed on the top of the second housing 32.

[0078] In some embodiments, the humidification assembly 4 further includes an adjustment member 44, which is disposed on one side of the humidification port 42 and configured to adjust the opening and closing degree of the humidification port 42.

[0079] In the above embodiment, the regulating component 44 can control the opening or closing of the humidification port 42 according to the actual humidity requirements in the first chamber 11, and adjust its opening degree to realize the on / off and flow control of the atomized airflow, alleviate excessive humidification or humidity fluctuations, improve the stability and control accuracy of the humidity environment in the first chamber 11, and enable the storage box to adaptively adjust the internal humidity under different environmental conditions.

[0080] In some embodiments, an adjustment element 44 is provided at each humidification port 42.

[0081] In some embodiments, the first adjusting member 44 includes a damper and a motor. The motor is driven and connected to the damper so that the damper blocks the humidification port 42, thereby closing the humidification port 42. Alternatively, the damper can be made to avoid the humidification port 42, thereby opening the humidification port 42. Or, the damper can be used to adjust the area of ​​the damper blocking the humidification port 42, thereby adjusting the opening size of the humidification port 42.

[0082] refer to Figure 3 and Figure 4 In some embodiments, the storage box includes a first partition 13 and a second partition 14, which separate a first compartment 11 and a second housing 32, forming a sandwich between the first partition 13 and the second partition 14.

A humidifying fan 43 is provided in the sandwich formed between the first partition 13 and the second partition 14 and communicates with the first compartment 11.

[0083] In some embodiments, the second partition 14 is provided with a return air vent 111. When the humidification vent 42 is closed, the humidification fan 43 can provide power to realize airflow between the interlayer and the first chamber 11. When the humidification vent 42 is open, the humidification fan 43 can provide power to allow the atomized airflow discharged from the humidification vent 42 to enter the first chamber 11 through the humidification fan 43.

[0084] refer to Figure 1 In some embodiments, the storage tank also includes a third evaporator 23, a first circulation pipeline 51, and a first water pump 61.

[0085] The third evaporator 23 is located in the first chamber 11.

[0086] The first circulation pipe 51 connects to the third evaporator 23 and the second housing 32.

[0087] The first water pump 61 is installed in the first circulation pipeline 51.

[0088] In the above embodiment, the first circulation pipe 51 connects the third evaporator 23 and the second housing 32, enabling the condensate collected in the second housing 32 to be transported to the third evaporator 23, and the condensate to be returned after circulation, thus achieving the reuse of condensate. The first water pump 61 is provided on the first circulation pipe 51 to provide circulation power and drive the condensate to flow between the second housing 32 and the third evaporator 23. The third evaporator 23 is located inside the first chamber 11 and directly exchanges heat with the first chamber 11, improving the response speed and uniformity of temperature regulation.

[0089] In the above embodiments, through the circulation of condensate, the third evaporator 23 can efficiently absorb or release heat, further enhancing the temperature control capability in the first chamber 11. Combined with the precise humidity control of the humidification component 4, a more stable and uniform constant temperature and humidity environment can be formed in the first chamber 11, improving the adaptability of the storage box to high-precision storage requirements.

[0090] In some embodiments, the storage tank further includes a first fan 91 disposed in the first compartment 11 and located below the third evaporator 23.

[0091] In the above embodiment, the first fan 91 is used to drive the air in the first chamber 11 to flow over the surface of the third evaporator 23, thereby enhancing the heat exchange efficiency between the air and the third evaporator 23, and improving the uniformity of temperature and humidity in the first chamber 11 by accelerating the air flow, thus avoiding local temperature differences.

[0092] Optionally, the first fan 91 includes a centrifugal fan.

[0093] In some embodiments, the storage tank further includes a first heating element 81, which is disposed in the first compartment 11 and located above the third evaporator 23.

[0094] In the above embodiment, in a low-temperature environment, the first heating element 81 is used to heat the air in the first chamber 11 to achieve active regulation of the temperature in the first chamber 11 and prevent the temperature in the first chamber 11 from being too low.

[0095] refer to Figure 1 and Figure 3 In some embodiments, the storage tank also includes a spray element 41 and a humidification port 42.

[0096] The spray element 41 is located inside the second box 32.

[0097] The humidification port 42 connects the first chamber 11 and the second box 32.

[0098] The first circulation pipeline 51 includes an inlet pipe 511 and an outlet pipe 512. The inlet pipe 511 connects the second box 32 to the inlet of the third evaporator 23, and the outlet pipe 512 connects the outlet of the third evaporator 23 to the spray element 41.

[0099] In the above embodiment, the spray element 41 can spray the condensate in the second box 32 to generate an atomized airflow; the humidification port 42 is used to introduce the atomized airflow generated by the spray element 41 into the first chamber 11; the water inlet pipe 511 is used to transport the condensate in the second box 32 to the third evaporator 23; and the water outlet pipe 512 is used to supply the condensate after heat exchange by the third evaporator 23 to the spray element 41. The first circulation pipe 51 connects the second housing 32, the third evaporator 23, and the spray element 41, forming a circulation channel for condensate. The condensate in the second housing 32 is transported to the third evaporator 23 via the inlet pipe 511, where it can exchange heat within the first chamber 11, achieving cooling or dehumidification of the storage space. The condensate after heat exchange flows into the spray element 41 via the outlet pipe 512, serving as a water source for atomized humidification, thus achieving water resource recycling. The spray element 41 atomizes the condensate, generating a fine water mist, which enters the first chamber 11 through the humidification port 42, increasing the internal humidity. Therefore, this embodiment can simultaneously achieve temperature and humidity regulation of the first chamber 11 through the recycling of condensate without the need for external water supply, significantly improving the efficiency and stability of constant temperature and humidity control.

The second pipeline 75 connects the control valve 73 and the connecting part 741 to form a branch. The control valve 73 is used to control the opening and closing of the second pipeline 75 to regulate whether the refrigerant flows into the first evaporator 21. When water production is not required, the control valve 73 controls the second pipeline 75 to disconnect, and the refrigerant enters the second evaporator 22 after being throttled through the first pipeline 74. It absorbs the heat of the condensate in the second housing 32 and evaporates, reducing the water temperature in the second housing 32. When water production is required, the control valve 73 connects the second pipeline 75, allowing some refrigerant to flow through the second pipeline 75 into the first evaporator 21, reducing the surface temperature of the first evaporator 21, promoting the condensation and precipitation of water vapor in the air on its surface, and realizing automatic water production.

[0127] refer to Figure 1 The third evaporator 23 is connected to the second housing 32 via a first circulation pipe 51, and a first water pump 61 is installed on the first circulation pipe 51. The fourth evaporator 24 is connected to the second housing 32 via a second circulation pipe 52, and a second water pump 62 is installed on the second circulation pipe 52. Both the third evaporator 23 and the fourth evaporator 24 are water-cooled evaporators.

[0128] The first compartment 11 and the second compartment 12 of the storage box are both temperature-controlled using water-cooled evaporators. The third evaporator 23 and the fourth evaporator 24 are independently controlled by the first water pump 61 and the second water pump 62, respectively. This allows the condensate from the second box 32 to be drawn into the evaporators and circulate. At the same time, the first fan 91 and the second fan 92 provide power to blow the air in the compartment onto the third evaporator 23 and the fourth evaporator 24 for heat exchange and cooling. Then, the air is sent out from above the third evaporator 23 and the fourth evaporator 24, thus achieving independent cooling and temperature control for each corresponding compartment.

[0129] The start / stop of the first fan 91 and the second fan 92 can be adjusted as needed to regulate the temperature. For constant temperature operation, the airflow temperature is first adjusted via the water-cooled evaporator, and then the fan speed is changed to maintain a gentle breeze. If the temperature continues to fall below the set temperature, both the water pump and the fans stop. Optionally, the first chamber 11 can be controlled at approximately 20°C, and the second chamber 12 can be controlled at approximately 16°C. The first chamber 11 can be used to store cigars, and the second chamber 12 can be used to store wine, etc.

[0130] The first heating element 81 is located above the third evaporator 23, and the second heating element 82 is located above the fourth evaporator 24. They are activated when the temperature inside the chamber or the ambient temperature is too low, and can compensate for the low temperature by using the first heating element 81 and the second heating element 82. For example, at an ambient temperature of 10°C, the water-cooled evaporator stops working, and the fan only works in conjunction with the heating elements to regulate the chamber temperature and maintain a constant temperature.

[0131] refer to Figure 1 , Figure 3 and Figure 4 A first partition 13 and a second partition 14 are provided between the first chamber 1 and the second box 32. A mezzanine is formed between the first partition 13 and the second partition 14. The first partition 13 can serve as the top plate of the second box 32. The second partition 14 can serve as the bottom plate of the first chamber 11. The humidification assembly 4 includes a spray element 41, a humidification port 42, a humidification fan 43, and an adjustment element 44. The spray element 41 is located on the top of the second box 32. The humidification port 42 is located on the first partition 13, connecting the second box 32 and the mezzanine. The humidification fan 43 is located in the mezzanine and connects the mezzanine and the first chamber 11. The humidification fan 43 is located adjacent to the humidification port 42 and is used to provide power so that the airflow in the second box 32 enters the mezzanine through the humidification port 42, and then enters the first chamber 11 through the humidification fan 43. The return air from the first chamber 11 flows to the mezzanine through the return air port 111. Two humidification ports 42 may be provided on the partition, but it is not limited to this. An adjusting member 44 is provided on one side of the humidification port 42. The adjusting member 44 may include a motor and a damper. The motor is driven and connected to the damper to control the damper to close or open the humidification port 42, and to control the opening degree of the humidification port 42.

[0132] The third evaporator 23 is connected to the second housing 32 via a first circulation pipe 51, and a first water pump 61 is installed on the first circulation pipe 51. The first circulation pipe 51 includes an inlet pipe 511 and an outlet pipe 512. The inlet pipe 511 connects the second housing 32 and the inlet of the third evaporator 23, and the outlet pipe 512 connects the outlet of the third evaporator 23 and the spray element 41. The spray element 41 sprays the condensate returned from the third evaporator 23 into the second housing 32, forming a water mist. When the humidity in the room is detected to be low, the humidifying fan 43 is turned on, and the humidification port 42 is opened. Figure 4 As shown, the humidifying fan 43 blows circulating air upwards, and water mist is drawn in by the humidifying fan 43 and sent upwards into the chamber to replenish the humidity of the chamber, thus achieving humidification. When sufficient humidity is detected, the motor drives the damper to close the humidifying port 42, and the humidifying fan 43 then circulates the air in the internal recirculation layer and the first chamber 11 to increase the airflow in the first chamber 11.

[0133] When the humidity in the room is too high, the heating element above the water-cooled evaporator can be activated to assist the water-cooled evaporator in heating up and dehumidifying. Alternatively, the temperature of the second evaporator 22 can be lowered to reduce the water temperature to below the dew point temperature of the air in the room, causing excess water vapor in the air in the room to condense on the water-cooled evaporator, thereby achieving dehumidification.

[0134] Figure 5 This is a view of the back of the storage box. A compressor 71, a condenser 72, and a fifth fan 95 are arranged on the back side of the first box 31 and the second box 32. A third fan 93 and a fourth fan 94 are arranged above the condenser 72. The third fan 93 and the fourth fan 94 are fresh air fans, controlling the airflow into and out of the first box 31, respectively. When outside air enters through the third fan 93 at the air inlet, as... Figure 2 As shown, the condensate passes through the first evaporator 21, cools, and condenses, then drips into the first box 31. An insulation layer is installed on the first box 31 to prevent cold air leakage. The first box 31 is equipped with a valve. When there is a large amount of water in the first box 31, the valve can be opened, allowing the condensate to enter the third box 33 for storage. The third box 33 is connected to the second box 32, and the condensate in the third box 33 enters the second box 32. When the water level in the second box 32 is high enough to cover the surface of the second evaporator 22, the first water pump 61 and the second water pump 62 can be activated to draw the condensate from the second box 32 to the upper and lower water-cooled evaporators, and then back into the second box 32, forming a refrigeration cycle.

[0135] refer to Figure 6The cooling capacity obtained by the second evaporator 22 is achieved through the compressor 71. The compressor 71, condenser 72, and second evaporator 22 are connected in sequence to form a refrigeration cycle system. A control valve 73 is located on a first pipe 74 between the condenser 72 and the second evaporator 22. A connecting part 741 is also provided on the first pipe 74, which is closer to the second evaporator 22 than the control valve 73. A second pipe 75 connects the control valve 73 and the connecting part 741, and the first evaporator 21 is located on the second pipe 75. The control valve 73 has two positions: in the first position, the second pipe 75 is disconnected, the second evaporator 22 operates, and the first evaporator 21 does not operate; in the second position, the second pipe 75 is connected, and both the first evaporator 21 and the second evaporator 22 operate simultaneously. A first one-way valve 76 and a first throttling element 78 are located on the first pipe 74, and the connecting part 741 is located between the first one-way valve 76 and the first throttling element 78. The first throttling element 78 is located near the second evaporator 22 relative to the first one-way valve 76. The first one-way valve 76 directs the refrigerant flowing from the condenser 72 to the second evaporator 22, preventing refrigerant backflow. The second one-way valve 77 and the second throttling element 79 are both located in the second pipeline 75. The first evaporator 21 is situated between the second one-way valve 77 and the second throttling element 79, with the second one-way valve 77 located near the connection portion 741 relative to the second throttling element 79. The second one-way valve 77 directs the refrigerant flowing from the first evaporator 21 to the second evaporator 22, preventing refrigerant backflow.

[0136] When low water levels are detected, control valve 73 switches to the second valve position, and the first evaporator 21 and the second evaporator 22 form a series cooling system. Each evaporator achieves its corresponding evaporation temperature through its respective throttling device, thus realizing cooling. When the fresh air supply is sufficient, control valve 73 switches to the first valve position. Due to the one-way valve, the first evaporator 21 is disabled, allowing only the second evaporator 22 to cool. Water flows and exchanges heat on the surface of the second evaporator 22, thereby controlling the water temperature within the second housing 32 within a certain temperature range (e.g., around 16°C). When the temperature is reached, compressor 71 stops. Because water has a certain specific heat capacity, the temperature of the entire water-cooled evaporator is close to the water temperature (e.g., 16°C) as it passes through the upper and lower water-cooled evaporators. At this time, the temperature fluctuation of the air blown into the room by the centrifugal fan is very small, which is beneficial for achieving constant temperature.

[0137] In some embodiments, all evaporation elements may be evaporators, and all condensation elements may be condensers. All throttling elements may be capillary tubes.

[0138] Some embodiments of this utility model also provide a cigar cabinet, which includes the storage box in any of the above embodiments.

[0139] In the above embodiments, the cigar cabinet includes a storage box, which has the beneficial effects of a storage box.

[0140] In some embodiments, the first compartment 11 of the cigar cabinet can be used to store cigars, and the second compartment 12 can be used to store red wine.

[0141] refer to Figure 7 Some embodiments of this utility model also provide a method for temperature and humidity control of the storage box of any of the above embodiments, which includes the following steps:

[0142] Determine whether the amount of condensate in the second box 32 has reached the preset water volume;

[0143] If the amount of condensate in the second box 32 reaches the preset water volume value, the second evaporator 22 is controlled to work, and the first evaporator 21 is not worked.

[0144] If the amount of condensate in the second housing 32 does not reach the preset amount, the first evaporator 21 and the second evaporator 22 will be controlled to work simultaneously.

[0145] In the above embodiment, the criterion for determining whether the amount of condensate in the second box 32 has reached the preset amount of water can be referred to whether the condensate in the second box 32 can cover the surface of the second evaporator 22. If the condensate in the second box 32 can cover the surface of the second evaporator 22, it can be considered that the preset amount of water has been reached.

[0146] In the above embodiment, when the second evaporator 22 is working, the refrigerant flows through the second evaporator 22 and exchanges heat with the condensate in the second box 32. It absorbs heat through the specific heat capacity of water or phase change and regulates the temperature and / or humidity in the first chamber 11. When the first evaporator 21 is working, the refrigerant flows through the first evaporator 21, which lowers its surface temperature and exchanges heat with the outside air, causing water vapor in the air to condense and precipitate on its surface, thus realizing the automatic water production function. By judging whether the amount of condensate is sufficient, the working states of the first evaporator 21 and the second evaporator 22 are dynamically switched or combined to ensure that there is enough condensate in the second box 32 for temperature and humidity regulation.

[0147] In some embodiments, when the amount of condensate in the second housing 32 reaches a preset amount, and the second evaporator 22 is controlled to operate while the first evaporator 21 is not operating, the following steps are also included:

[0148] The system detects whether the water temperature in the second box 32 has reached the first preset temperature value, and at the same time detects whether the humidity in the first chamber 11 is higher than the preset humidity upper limit value.

[0149] If the water temperature in the second box 32 reaches the first preset temperature value, and at the same time, the humidity in the first chamber 11 is not higher than the preset upper humidity value and not lower than the preset lower humidity value, then the compressor 71 in the circulating refrigeration system where the second evaporator 22 is located is controlled to stop.

[0150] In the above embodiment, the second evaporator 22 continuously absorbs heat from the condensate in the second box 32 during operation, causing the water temperature to gradually decrease. This, in turn, lowers the temperature of the first chamber 11 through heat exchange and promotes the condensation of water vapor in the air, achieving cooling and dehumidification. When the water temperature in the second box 32 drops to the first preset temperature value, it indicates that the system has sufficient low-temperature medium for environmental control. At the same time, if the humidity in the first chamber 11 is not higher than the preset upper humidity value and not lower than the preset lower humidity value, it indicates that the current humidity meets the storage requirements and no further dehumidification is needed. Under these dual conditions, it is determined that the temperature and humidity adjustment target has been achieved, and continuing to run the refrigeration system will lead to energy waste or the risk of overcooling. Therefore, the compressor 71 is controlled to stop, terminating the refrigeration cycle and putting the system into standby or low-power state. Thus, by using water temperature and chamber humidity as joint control parameters, accurate start-stop management of the refrigeration process is achieved, maintaining a stable constant temperature and humidity environment in the first chamber 11.

[0151] In the above embodiments, the preset upper humidity limit is greater than the preset lower humidity limit. Optionally, the preset upper humidity limit is approximately 68%, and the preset lower humidity limit is approximately 65%.

[0152] In some embodiments, after the compressor 71 in the refrigeration cycle system in which the second evaporator 22 is located is stopped, the following steps are also included;

[0153] Check whether the temperature inside the first room 11 has reached the second preset temperature value;

[0154] If the temperature in the first chamber 11 does not reach the second preset temperature value, the first water pump 61 is controlled to continue to operate to continuously provide power to send the condensate in the second box 32 to the third evaporator 23 in the first chamber 11.

[0155] In the above embodiment, after the compressor 71 stops, the refrigeration cycle terminates, and the second evaporator 22 no longer actively refrigerates. However, the second housing 32 still stores condensate that has been cooled to the first preset temperature value, which has the potential to continue heat exchange. By detecting the actual temperature in the first chamber 11, it is determined whether further cooling is still needed. When the temperature of the first chamber 11 has not yet reached the second preset temperature value, i.e., the target low temperature value, it indicates that there is still a cooling demand. At this time, the first water pump 61 is kept running, driving the low temperature condensate to flow continuously in the first circulation pipeline 51, flowing through the third evaporator 23 to participate in the heat exchange in the chamber, and using its specific heat capacity to achieve "cold storage and release". The condensate absorbs heat from the first chamber 11 during the flow process, gradually reducing its temperature until it reaches the second preset temperature value. Thus, after the compressor 71 stops, the stored cold energy can still be used for subsequent cooling, realizing the full utilization of cold energy and avoiding waste of cold energy.

[0156] In the above embodiment, the second preset temperature value is greater than the first preset temperature value.

[0157] Optionally, the first preset temperature value can be around 16℃, and the second preset temperature value can be around 18℃.

[0158] In some embodiments, if the temperature in the first chamber 11 reaches a second preset temperature value, the first water pump 61 is controlled to turn off, the first fan 91 in the first chamber 11 remains on, and the humidifying fan 43 of the humidifying assembly 4 remains on.

[0159] In the above embodiment, when the temperature in the first chamber 11 has reached the second preset temperature value, it indicates that the current temperature adjustment target has been achieved and there is no need to continue the cooling operation. At this time, the first water pump 61 is turned off to stop the circulation of condensate in the first circulation pipe 51 and avoid unnecessary energy consumption. At the same time, the first fan 91 in the first chamber 11 remains on and the humidifying fan 43 of the humidifying component 4 remains on, keeping the humidifying component 4 running continuously and using the condensate stored in the second box 32 to atomize and humidify the first chamber 11.

[0160] In some embodiments, when it is determined that the amount of condensate in the second housing 32 has reached a preset amount, the second evaporator 22 is controlled to operate, and the first evaporator 21 is not operated, the following steps are also included:

[0161] The system detects whether the water temperature in the second box 32 has reached the first preset temperature value, and at the same time detects whether the humidity in the first chamber 11 is higher than the preset humidity upper limit value.

[0162] If the water temperature in the second chamber 32 does not reach the first preset temperature value, and at the same time, the humidity in the first chamber 11 is higher than the preset humidity upper limit value, then the second evaporator 22 will remain in working condition.

[0163] In the above embodiment, the second evaporator 22 operates continuously, allowing the refrigerant to flow continuously through its interior and exchange heat with the condensate in the second housing 32, gradually reducing the water temperature and reserving sufficient cooling capacity for subsequent temperature and humidity regulation. At the same time, the humidity in the first chamber 11 is higher than the preset upper limit, indicating that the humidity is too high. By maintaining the operation of the second evaporator 22, the temperature of the condensate can be further reduced, thereby enhancing its dehumidification capacity when exchanging heat with the air during circulation. In addition, when the low-temperature condensate flows through the third evaporator 23 or comes into contact with the air, it can more effectively promote the condensation and precipitation of water vapor, accelerating the reduction of the humidity in the first chamber 11. Thus, under the dual conditions of water temperature not meeting the standard and humidity being too high, the continuous operation of the second evaporator 22 ensures that the system simultaneously achieves cooling and active dehumidification, enabling the first chamber 11 to quickly approach and stabilize within the set constant temperature and humidity target range.

[0164] In some embodiments, when it is determined that the amount of condensate in the second housing 32 has reached a preset amount, the second evaporator 22 is controlled to operate, and the first evaporator 21 is not operated, the following steps are also included:

[0165] The system detects whether the water temperature in the second box 32 reaches the first preset temperature value, and at the same time detects whether the humidity in the first chamber 11 is lower than the preset humidity lower limit value.

[0166] If the water temperature in the second box 32 reaches the first preset temperature value, and at the same time, the humidity in the first chamber 11 is lower than the preset humidity lower limit value, then the humidification component 4 is controlled to continue to work, and the humidification component 4 continues to use the condensate in the second box 32 to humidify the first chamber 11.

[0167] In the above embodiment, when the water temperature in the second box 32 has dropped to the first preset temperature value, it indicates that the system has a stable cold source and can maintain the current water temperature. At the same time, if the humidity in the first chamber 11 is lower than the preset humidity lower limit, it indicates that the environment is too dry and water needs to be added to maintain the constant humidity requirement. Under this condition, the humidification component 4 is controlled to run continuously, using the condensate stored in the second box 32 as a water source, and atomizing it through the spray component 41 to generate fine water mist. The atomized airflow enters the first chamber 11 through the humidification port 42 and the humidification fan 43 to increase the water vapor content in the air and increase the relative humidity.

[0168] In some embodiments, when it is determined that the amount of condensate in the second housing 32 has reached a preset amount, the second evaporator 22 is controlled to operate, and the first evaporator 21 is not operated, the following steps are also included:

[0169] The system detects whether the water temperature in the second box 32 reaches the first preset temperature value, and at the same time detects whether the humidity in the first chamber 11 is lower than the preset humidity lower limit value.

[0170] If the water temperature in the second chamber 32 reaches the first preset temperature value, and the humidity in the first chamber 11 is not lower than the preset lower humidity limit and not higher than the preset upper humidity limit, then the humidification port 42 is closed, and the condensate in the second chamber 32 is no longer used to humidify the first chamber 11. The humidification fan 43 can remain on to circulate the first chamber 11 and the interlayer, improving the temperature uniformity in the first chamber 11.

[0171] In the above embodiment, when the water temperature in the second box 32 reaches the first preset temperature value, it indicates that the system has sufficient cooling capacity to meet the temperature control requirements. At the same time, if the humidity in the first chamber 11 is within the target range between the preset lower humidity limit and the preset upper humidity limit, it indicates that the current humidity has met the set requirements and no further humidification is needed. Under this condition, the humidification port 42 is closed to interrupt the delivery of atomized airflow, avoid over-humidification, and keep the temperature and humidity of the first chamber 11 stable within the set range, ensuring the accuracy, energy efficiency, and reliability of constant temperature and humidity control.

[0172] The temperature and humidity control method for the storage box provided in this embodiment of the invention can automatically determine and switch the working mode based on the amount of condensate in the second box 32, realizing the autonomous acquisition and dynamic control of water resources during system operation. It can automatically produce water without the need for external water supply, and uses a water volume feedback mechanism to control the start and stop of the water production process, ensuring a continuous supply and rational utilization of water resources. By controlling the second evaporator 22 to cool the condensate in the second box 32, the high specific heat capacity of water is used to store cold energy, and the cooled condensate is circulated to the compartment for heat exchange, achieving stable temperature regulation of the compartment and fully leveraging the advantages of water cooling: uniform cooling, large heat capacity, and precise temperature control.

[0173] The following is in conjunction with the appendix Figure 7 This describes some specific embodiments of the temperature and humidity control method for the storage tank.

[0174] In some specific embodiments, the temperature and humidity control method for the storage tank includes the following steps:

[0175] S10: Detect the amount of water in the first box 31 and determine whether the amount of water in the first box 31 is sufficient to submerge the second evaporator 22 in the second box 32.

[0176] A water level sensor is installed inside the first box 31. When there is too much water in the first box 31, the switch valve opens, and the condensate in the first box 31 flows into the third box 33 below. The third box 33 is connected to the second box 32 arranged side by side. The condensate in the third box 33 enters the second box 32. The second evaporator 22 is installed inside the second box 32. At the same time, a water level sensor is also installed in the second box 32, mainly used to detect whether there is enough water in the second box 32. The criterion is whether the condensate can submerge the second evaporator 22.

[0177] S20: If the water volume is insufficient, the control valve 73 continues to switch to the second valve position, the second pipeline 75 is connected, and the first evaporator 21 and the second evaporator 22 work simultaneously.

[0178] If there is enough water, control valve 73 switches to the first valve position, the second pipeline 75 is disconnected, only the second evaporator 22 works, the first water pump 61 continues to run, realizing the circulation of condensate in the second evaporator 22, the first evaporator 21 does not work, and at the same time the third fan 93 and the fourth fan 94 also stop working.

[0179] When there is sufficient water and the second evaporator 22 is operating while the first evaporator 21 is not operating, proceed to steps S30 and S40, which are parallel steps.

[0180] S30: Detect whether the water temperature in the second box 32 has reached the first preset temperature value (e.g., 16℃), and at the same time detect whether the humidity in the first chamber 11 is higher than the preset humidity upper limit value (e.g., greater than or equal to 68%); the judgment process includes parallel steps S31 and S32.

[0181] S31: If the water temperature in the second box 32 does not reach the first preset temperature value, and the humidity in the first chamber 11 is higher than the preset humidity upper limit value, then the second evaporator 22 is kept running, and the water temperature is lowered according to the humidity control conditions so that the water temperature is lower than the first preset temperature value, for example: 14℃.

[0182] In step S31, if the humidity in the first chamber 11 is higher than the preset upper limit of humidity, it means that the humidity in the first chamber 11 is too high and needs to be dehumidified. At this time, the second evaporator 22 is kept running and the water temperature is controlled to be lower, for example, 14°C. Then the temperature of the third evaporator 23 is 14°C. The return air in the first chamber 11 enters the third evaporator 23 and condenses to form water, thus achieving dehumidification.

[0183] S32: If the water temperature in the second box 32 reaches the first preset temperature value, and at the same time, the humidity in the first chamber 11 is not higher than the preset upper humidity value and not lower than the preset lower humidity value, then the compressor 71 in the circulating refrigeration system where the second evaporator 22 is located is controlled to stop.

[0184] In step S32, the humidity in the first chamber 11 is neither higher than the preset upper humidity limit nor lower than the preset lower humidity limit, maintaining humidification. Humidification does not require the compressor 71; only the humidification port 42 needs to be opened. At this time, the compressor 71 only controls the cooling water temperature. During dehumidification, the compressor needs to be turned on to lower the water temperature.

[0185] Proceed from step S32 to step S321.

[0186] S321: Then detect whether the temperature in the first room 11 has reached the second preset temperature value (e.g., 18℃). The second preset temperature value is greater than the first preset temperature value.

[0187] If the temperature in the first room 11 does not reach the second preset temperature value, the first water pump 61 will continue to be turned on, and all fans will remain on.

[0188] If the temperature in the first chamber 11 reaches the second preset temperature value, the first water pump 61 is turned off, the first fan 91 (centrifugal fan) remains on, and the humidifying fan 43 remains on.

[0189] In step S321, if the set temperature of the first chamber 11 is 18°C, the water temperature in the second box 32 is controlled at 16°C. When this water temperature is reached, the compressor 71 stops, the second evaporator 22 stops active cooling, and the cooling capacity of the water is used to provide the third evaporator 23 with an evaporation temperature of 16°C through the first water pump 61 to cool the chamber. The cooling target is 18°C, while avoiding large temperature differences that cause large fluctuations in the chamber temperature.

[0190] In step S321, reaching the water temperature does not necessarily mean that the compartment temperature has reached 18°C. Therefore, even if the compressor 71 stops at this point, the 16°C condensate can still be circulated by the first water pump 61 to cool the compartment. The compressor 71 is stopped at this time to avoid excessively low water temperature, which would cause large fluctuations in the compartment temperature. In other words, the compressor 71 and the second evaporator 22 only control the water temperature; while the compartment temperature is controlled by the water temperature and the first fan 91.

[0191] S40: Detect whether the water temperature in the second box 32 has reached the first preset temperature value, and at the same time detect whether the humidity in the first chamber 11 is lower than the preset humidity lower limit value (e.g., 65%); the judgment process includes parallel steps S41 and S42.

[0192] S41: If the water temperature in the second box 32 reaches the first preset temperature value, and at the same time, the humidity in the first chamber 11 is lower than the preset humidity lower limit value, then control the humidification port 42 to open and the humidification fan 43 to turn on.

[0193] S42: If the water temperature in the second box 32 reaches the first preset temperature value, and at the same time, the humidity in the first chamber 11 is not lower than the preset lower humidity limit and not higher than the preset upper humidity limit, then control the humidifying fan 43 to turn on and the humidifying port 42 to turn off.

[0194] In the above process, the temperature of the chamber is adjusted by a water pump and a fan, the humidification is adjusted by a humidifying fan 43 and a humidifying port 42, and the dehumidification is achieved by lowering the temperature so that the temperature of the third evaporator 23 is lower than the dew point temperature.

[0195] In some specific embodiments, the temperature in the first chamber 11 is controlled at 18°C, and the humidity in the first chamber 11 is controlled at 65%~68%. The water temperature in the second box 32 is controlled at 16°C.

[0196] If the water temperature in the second chamber 32 does not reach the controlled temperature of 16℃, and the humidity in the first chamber 11 is too high (greater than or equal to 68%), dehumidification is required. In this case, the second evaporator 22 is kept running, and the water temperature is lowered according to the humidity control requirements. The temperature of the third evaporator 23 decreases accordingly, and the air supply temperature also decreases. When it is lower than the dew point temperature of the air in the first chamber 11, the moisture in the air in the first chamber 11 will condense on the third evaporator 23, achieving the dehumidification effect. At this time, the humidification port 42 and the humidification fan 43 are closed simultaneously, thus controlling the humidity in the first chamber 11 to 65%~68%.

[0197] If the temperature of the first chamber 11 is higher than 18°C, the temperature of the second evaporator 22 is lowered, and the condensate circulating from the first water pump 61 continuously cools the chamber. If the temperature of the first chamber 11 is lower than 18°C, the first water pump 61 is turned off to maintain the chamber temperature between 18°C ​​and 20°C. Because water has a specific heat capacity, the supply air temperature changes little, and can even be controlled within a temperature difference range of 0.5°C. Therefore, large temperature fluctuations in the first chamber 11 can be prevented.

[0198] When the water temperature in the second chamber 32 reaches the controlled temperature of 16℃ and the humidity in the first chamber 11 is less than 68℃, the compressor 71 stops. The compressor's cooling function only regulates the temperature of the second evaporator 22; after the conversion of water's heat capacity, temperature fluctuations are minimal. When the water temperature reaches 16℃, the first water pump 61 operates, supplying circulating water to the third evaporator 23 at 16℃, meaning the evaporation temperature of the third evaporator 23 is 16℃, and the air supply temperature is between 16℃ and 18℃, allowing for relatively precise control of the temperature in the first chamber 11 to 18℃. After the temperature in the first chamber 11 is reached, it is necessary to determine if the humidity is too low or too high. If it is too low, the humidifying fan 43 and the humidifying port 42 are activated to humidify the first chamber 11. If the humidity is too high, the temperature of the second evaporator 22 is lowered, causing the water temperature to drop, the third evaporator 23 to cool down, and the air supply temperature to decrease, thus achieving a dehumidification effect. When the temperature and humidity of the first chamber 11 reach the set value, in order to prevent the water temperature from being too low, the compressor 71 can be stopped and the water can be cooled by utilizing its heat capacity.

[0199] In some embodiments of this invention, the temperature of the first chamber 11 is controlled at 18°C ​​because cigars are best stored at this temperature. If the temperature does not reach 18°C, it indicates that the temperature is too high and cooling is required. The first water pump 61 provides power to draw water at 14°C to 16°C to the third evaporator 23, and the first fan 91 blows out cold air to cool the first chamber 11. When the temperature reaches 18°C, the first water pump 61 stops circulating, and the water temperature in the third evaporator 23 no longer remains at 14°C to 16°C. Due to heat exchange and heat leakage with the first chamber 11, the temperature will gradually rise. At this time, the first fan 91 continues to operate to agitate the airflow in the first chamber 11, prevent the cold air from sinking, and prevent a temperature difference between the top and bottom of the first chamber 11. At this time, the humidifying fan 43 also plays the role of stirring the air flow in the first chamber 11. If the humidity is not enough, the humidifying port 42 will open to humidify. If the humidity is reached, the humidifying port 42 will close. At this time, the humidifying fan 43 will run to improve the temperature uniformity of the first chamber 11.

[0200] The humidifying fan 43 has two functions. When the humidifying port 42 is closed, it acts as a heat exchanger that agitates the airflow in the first chamber 11, similar to a circulating fan. When the humidifying port 42 is open, it becomes a humidifying fan 43, supplying air to the first chamber 11 and humidifying it.

[0201] In this embodiment, 18℃~20℃ is the ideal temperature for storing cigars, and the ideal humidity range for cigars is 65%~68%. However, since there are many types of cigars, not all may be suitable for this temperature and humidity range. In actual use, the temperature and humidity of the storage room can be adjusted according to different types of cigars or different foods (such as red wine, delicate fruits and vegetables, etc.).
