Description

Technical Field

[0001] The invention relates to the field of electronic control of cigar cabinets, and in particular to a constant temperature and humidity cigar cabinet and a temperature and humidity control method thereof. Background Art

[0002] The preservation of cigars is extremely important for cigar lovers, because improper storage environment will cause cigars to deteriorate or lose their unique flavor. Therefore, professional cigar storage equipment such as constant temperature and humidity cigar cabinets came into being to meet the needs of cigar lovers for high-quality storage. Constant temperature and humidity cigar cabinets can maintain a relatively stable temperature and humidity environment, usually set at 18℃~21℃, and relative humidity at 60%~70%. Such an environment is conducive to the aging and maintenance of cigars, avoiding damage to cigars caused by temperature and humidity fluctuations.

[0003] In case of emergencies, such as power outages or failures in the constant temperature and humidity system, when the temperature and humidity are too low, the cigars may dry, crack or lose the aroma and taste of the tobacco leaves, affecting the preservation of the cigars and making them too hard to ignite. When the temperature and humidity are too high, the cigars may become moldy, grow insects or lose their flavor, accelerate the fermentation process of the cigars, and cause the cigars to age or deteriorate prematurely, resulting in irreversible damage to the cigars. High-end cigars are expensive and once damaged, they will face huge economic losses. In addition, different ambient temperatures will also cause temperature fluctuations in the cigar cabinet. Therefore, in view of the above-mentioned weather changes, emergency power outages or failures in the constant temperature system, which may cause irreversible damage to the cigars and face huge economic losses, a constant temperature and humidity control system can be designed to ensure that the temperature and humidity are more stable, and in the event of a failure, the alarm can be used to notify the user in the first time to conduct inspection and maintenance and uninterrupted power supply to ensure the safety of high-end cigar storage.

By setting the heating coil, the system can adjust the temperature when necessary to ensure that the cigars are always in the best storage environment.

[0043] In one embodiment, the constant temperature and humidity control method for a cigar cabinet comprises the following steps:

[0044] S1. Set a target temperature and humidity value, and then collect first temperature and humidity data of a first overall temperature and humidity sensor 410, wherein the first overall temperature and humidity sensor is installed on the top of the cabinet;

[0045] S2, collecting second temperature and humidity data of a second independent temperature and humidity sensor 7, wherein the second independent temperature and humidity sensor 7 is installed at the top of the cabinet and is adjacent to the first overall temperature and humidity sensor;

[0046] S3, collecting third temperature and humidity data of a third external environment temperature and humidity sensor 26, wherein the third external environment temperature and humidity sensor is installed outside the cabinet;

[0047] S4, collecting temperature gradient data corresponding to the fourth temperature and humidity data of the fourth internal environment temperature and humidity gradient sensing linear array 27;

[0048] The first temperature and humidity data, the second temperature and humidity data, the third temperature and humidity data, and the fourth temperature and humidity data are sent to the constant temperature and humidity block controller 402, and the temperature and humidity control strategy is determined based on the temperature and humidity data.

[0049] The step S4 further includes:

[0050] Step S41, determining a first difference between the first temperature and humidity data and the second temperature and humidity data, including determining a temperature difference and a humidity difference; if the temperature and humidity differences are both less than a predetermined difference, proceed to step S42; otherwise, an error message is prompted and a system fault alarm is issued;

[0051] Step S42, calculating a second difference between the first temperature and humidity data and the target temperature and humidity value;

[0052] Step S43, calculating a third difference between the third temperature and humidity data and the target temperature and humidity value;

[0053] Step S44, calculating the gradient dispersion value of the temperature and humidity gradient data;

[0054] Step S45, calculating the temperature and humidity control parameters of the constant temperature and humidity block based on the second difference, the third difference, and the gradient dispersion value.

[0055] In the present invention, since a temperature and humidity sensor is installed outside the cabinet, the temperature and humidity data of the external environment of the cigar cabinet can be measured. At the same time, a temperature and humidity sensor is installed inside the cabinet, so the temperature difference between the inside and outside of the cabinet can be compared. The temperature environment where cigars need to be stored is usually set at 18°C ​​to 21°C and the relative humidity is 60% to 70%. In the case where the difference between the ambient temperature and the set temperature of the cigar cabinet is large, the cigar cabinet itself will interact with the external heat more quickly, making the temperature fluctuation of the cigar cabinet more intense. Therefore, a corresponding adjustment strategy is required; at the same time, when the ambient temperature is close to the set temperature, the degree of heating and humidification needs to be controlled more gently to avoid strong disturbances;

[0056] Furthermore, the present invention is provided with a fourth internal environment temperature and humidity gradient sensing array 27. Since the air circulation between different shelves is subject to certain obstructions and restrictions, the temperature transfer and distribution between different shelves are different. The fourth temperature and humidity data of the present invention corresponds to the temperature gradient data between the shelves. When the temperature gradient data shows that the temperature difference between the shelves is large, it is necessary to increase the air circulation in time to balance the temperature difference between the shelves as soon as possible. Traditional storage cabinets do not have this function.

[0057] The second difference includes a temperature difference Td2 and a humidity difference Sd2, the third difference includes a temperature difference Td3 and a humidity difference Sd3, and the gradient dispersion value includes a temperature dispersion value Ta and a humidity dispersion value Sa;

[0058] Calculating the temperature and humidity control parameters includes: calculating the controller set temperature Tac, calculating the controller set power PTac, and calculating the humidity power PSac and the air circulator power PA. The controller set temperature Tac refers to setting the temperature value of the refrigerator or the heating coil so that the controller starts the cooling function or the heating function; the controller set power PTac refers to setting the power of the heating coil or the refrigeration compressor of the constant temperature and humidity block, preferably, the fan power PA of the air circulator is controlled at the same time; the humidity power PSac refers to the fan power of the humidifier;

[0059] Furthermore, the controller set temperature Tac is calculated as follows:

[0060] Tac=OBT+a*(Td2)+b*(Td3)+c*(Ta);

[0061] The controller set power PTac is calculated as follows:

[0062] PTac=Pb*Tac / OBT;

[0063] Wherein, a, b, c are coefficients less than 1, and a+b+c=1; OBT is the set target temperature, and Tac is the temperature used by the controller for heating or cooling; in a preferred embodiment, a=0.3, b=0.6, c=0.1;

[0064] Td2 = first temperature data - target temperature value, Td3 = third temperature data - target temperature value; the temperature dispersion value Ta is calculated as follows:

[0065] Ta=((Ta2-Ta1)+(Ta3-Ta2)+…(Ta n -Ta n-1 )) / N,

[0066] By calculating the difference between the temperature sensors of two adjacent shelves and accumulating and averaging them, the value of the overall temperature gradient dispersion is obtained;

[0067] Pb is the rated power of the compressor or heating coil, Ta n is the temperature of the nth layer of sub-temperature and humidity sensors, N is the number of sub-temperature and humidity sensors;

[0068] Furthermore,

[0069] Sac=OBS+a*(Sd2)+b*(Sd3)+c*(Sa);

[0070] PSac=PSb*Sac / OBS;

[0071] Wherein, a, b, c are coefficients less than 1 as mentioned above, and a+b+c=1; OBS is the set target humidity, and Sac is the humidity used by the controller for humidification;

[0072] Sd2 = first humidity data - target humidity value, Sd3 = third humidity data - target humidity value; humidity dispersion value Sa is calculated as follows:

[0073] Sa=((Sa2-Sa1)+(Sa3-Sa2)+…(Sa n -Sa n-1 )) / N;

[0074] Sa n is the temperature of the nth layer of sub-temperature and humidity sensors. By calculating the difference between the humidity sensors of two adjacent layers and accumulating and averaging, the value of the overall humidity gradient dispersion is obtained;

[0075] PSb is the rated power of the humidifier. Generally speaking, this power is the power of the humidifier's blowing fan.

[0076] Finally, calculate the fan power of the air circulator:

[0077] The fan power of the air circulator PA = d*Ta*PAb+e*Sa*PAb;

[0078] PAb is the rated power of the air circulator fan, d+e=1, d and e are coefficients greater than 0 and less than 1, preferably d is 0.5 and e is 0.5.

[0079] In this embodiment, the temperature difference between the inside and outside of the cigar cabinet, the difference between the target temperature and the current temperature, and the temperature distribution difference between different shelves in the cabinet are taken into consideration to determine the degree of cooling, heating, and humidification, thereby dynamically adjusting the temperature control intensity, so that the temperature adjustment process of the cigar cabinet is smoother, thereby avoiding the problem of large temperature fluctuations caused by directly performing temperature control by only considering the difference between the set target temperature and the cabinet temperature; preferably, at the same time, when the temperature gradient dispersion value in the cabinet is greater than a predetermined value, the power of the air circulator is further increased to make the air circulate faster and the temperature distribution more balanced faster.

[0080] Furthermore, the present invention also includes a temperature control function, that is, real-time judgment of the temperature and humidity of the first overall temperature and humidity sensor in the box. If it is greater than the target set temperature, heating is started; if it is lower than the target set temperature, cooling is started; if the humidity is higher than the target set humidity, humidification is turned off; if it is lower than the target set humidity, humidification is started. This is the prior art and will not be repeated here.

[0081] In another embodiment, see Figure 1 - Figure 3 In this embodiment, an alarm 5 is provided on the outside of the set-top shell 9, and a receiver 20 (the model of the receiver 20 is nRF24L01) corresponding to the alarm 5 is provided inside the set-top shell 9. The alarm 5 is arranged on the outside of the set-top shell 9 to ensure that the alarm 5 can still work normally even if there is a fault or power failure inside the set-top shell 9. The constant temperature and humidity cigar cabinet can not only immediately issue an alarm when an abnormal situation is detected, but also ensure that the alarm signal can be correctly identified and processed by the system, which not only improves the safety of the system, but also provides users with greater convenience and peace of mind. A connecting rod 21 is provided between the alarm 5 and the receiver 20, and the receiver 20 is connected to the second independent temperature and humidity sensor 7. The backup battery 16, the inverter 17 and the rectifier 1 8 is provided with a connecting cable 19, an inverter 17 for converting direct current into alternating current and providing stable power for connected devices and a rectifier 18 for converting alternating current into direct current, charging the battery and providing stable direct current power for the inverter 17 are provided between the protective shell 22 and the top shell 9, the receiver 20 is directly connected to the second independent temperature and humidity sensor 7, and can receive the data of temperature and humidity changes in time, and judge whether to trigger an alarm based on these data, through the combination of the backup battery 16, the inverter 17 and the rectifier 18, the system can continue to work when the main power is interrupted, thereby improving the overall reliability, and the alarm 5 is directly connected to the receiver 20 through the connecting rod 21, which reduces the signal delay and ensures that the alarm can be triggered immediately when an abnormality is detected.

[0082] See also Figure 1 - Figure 3In this embodiment, a sliding groove 6 corresponding to the sliding plate 10 is provided on the inner side of the cabinet box 2, and a plurality of groups of placement grooves 11 are provided on the surface of the sliding plate 10. A ventilation groove 12 is provided at the bottom of the placement groove 11. A first handle 13 is provided on the outer side of the sliding plate 10. The user can easily pull out the sliding plate 10 by pulling the first handle 13, and storing and accessing cigars becomes very simple. The design of the sliding plate 10 allows the user to store and access cigars without fully opening the cabinet door, reducing the chance of the internal environment being disturbed by the outside world. The plurality of groups of placement grooves 11 can help the user to better organize and classify cigars, and facilitate the management and search of specific brands of cigars. A door frame 15 is provided on the outer side of the cabinet box 2, and a glass plate 3 is provided in the center of the door frame 15. A second handle 14 is provided on the outer side of the door frame 15. By organically combining the door frame 15, the glass plate 3 and the second handle 14, the constant temperature and humidity cigar cabinet not only meets the actual needs of the user in terms of function, but also reaches a higher standard in appearance design. This design not only enables the user to manage and display his cigar collection more conveniently, but also ensures that the cigars are preserved in the best environment.

[0083] When working, first power on the device, open the door frame 15, put the cigar into the placement slot 11 on the sliding plate 10, and close the door frame 15 after placement. The user can observe the condition of the cigar through the glass plate 3, and set the humidity and other parameters through the control panel 8 according to the temperature and humidity required by the cigar. After the parameters are adjusted, the constant humidity and constant temperature block will start to operate. The air circulator 401 is responsible for forming a stable airflow inside the cigar cabinet to ensure that the temperature and humidity are evenly distributed. The controller 402 is the brain of the entire system, responsible for receiving data from the sensor and controlling the operation of other components according to preset conditions. The humidifier 403 uses steam humidification to increase the moisture content in the air. The compressor 404 compresses the refrigerant to increase its pressure and temperature to provide power for the refrigeration cycle. The condenser 405 cools the high-temperature and high-pressure gas discharged by the compressor 404 into a liquid state to release heat. The evaporator 406 absorbs heat from the liquid refrigerant to reduce the temperature inside the cabinet. The first overall temperature and humidity sensor 410 is used to monitor the temperature and humidity inside the cabinet in real time. The evaporator 406 adjusts the temperature when frost forms on the surface or there is a temperature difference. The connecting line 407 connects all components, including sensors, controllers and other actuators, to ensure that data and control signals can be transmitted accurately. These devices are used to control the constant temperature and humidity of the protection cabinet. When the constant temperature and humidity system fails in an emergency, the alarm 5 will sound an alarm to remind the user in the first time. In the event of a power outage, the system can continue to work when the main power is off through the combination of the backup battery 16, the inverter 17 and the rectifier 18 to ensure the safety of the cigars. When you need to take out the cigars, open the door frame 15 by opening the second handle 14, and then pull open the sliding plate 10 through the first handle 13 to take out the cigars.

[0084] Through the above steps, when the environmental conditions of the new cigar cabinet exceed the preset safety range, the alarm 5 can immediately notify the user, and can also be used to prompt regular maintenance or inspection to ensure that the equipment is in the best working condition. In the event of a power outage, the backup power supply can also ensure that the data in the control system will not be lost due to sudden power outages, maintaining the continuity and accuracy of system settings. The uninterrupted power supply helps to reduce the risk of damage to the equipment due to voltage fluctuations, thereby extending the service life of the cigar cabinet. Through the backup battery 16, the user can use the cigar cabinet more assured, and the safe storage environment of cigars can be guaranteed even in unforeseen circumstances. The addition of the alarm 5 and the backup battery 16 makes the constant temperature and humidity cigar cabinet not only safer and more reliable, but also maintains good performance in various emergency situations. This has a better protection effect on precious cigars, and has solved the problem that in the event of an emergency power outage or a failure of the constant temperature system, the cigars may be irreversibly damaged and face huge economic losses.
