Obviously, the described embodiments are only some, not all, of the embodiments of this application. Other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are all within the protection scope of this application.

Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0048] Furthermore, in this application, directional terms such as "inner" and "outer" are defined relative to the orientation of the components shown in the accompanying drawings.

[0049] A cigar cabinet is a temperature and humidity refrigeration appliance used to store cigars. The interior of the compartment where cigars are placed needs to maintain a constant temperature and humidity environment between 16°C and 22°C and between 65% and 75% to meet the storage requirements of cigars.

[0050] Existing cigar cabinets typically use fixed-frequency compressors for cooling and dehumidification. However, adjusting the temperature inside the cabinet causes fluctuations in humidity, and vice versa. For example, heating the cabinet simultaneously increases the humidity, resulting in significant humidity variations. Furthermore, because fixed-frequency compressors not only cool but also dehumidify, cooling the cabinet also lowers the humidity, leading to substantial fluctuations in the storage environment.

[0051] To address the aforementioned problems, this application provides a variable frequency constant temperature and humidity cigar cabinet and its control method. The method acquires the ambient temperature and the internal temperature of the cigar cabinet compartment; compares the ambient temperature with a set temperature, and compares the internal temperature with the set temperature; in response to both the ambient and internal temperatures being lower than the set temperature, a heating device is used to heat the cigar cabinet compartment; it then determines whether the cigar cabinet requires dehumidification; and in response to this, it controls the variable frequency compressor to operate at a first speed, where the magnitude of the first speed is proportional to the absolute value of the difference between the ambient and set temperatures. When both the internal and external temperatures are lower than the set temperature, the compartment needs to be heated. During this heating process, the humidity inside the compartment may rise. By determining whether dehumidification is needed, the humidity inside the compartment can be adjusted promptly. Meanwhile, by making the speed of the variable frequency compressor proportional to the absolute value of the difference between the ambient temperature and the set temperature, rapid dehumidification can be achieved under large temperature differences. While considering the influence of the external environment, the temperature and humidity within the storage compartment can be adjusted in a timely manner, helping to maintain stable storage conditions. In other words, this application achieves synchronous adjustment of temperature and humidity by simultaneously monitoring humidity changes within the storage compartment while regulating the temperature, thereby reducing the impact of changes in one parameter on the other. Furthermore, by using a variable frequency compressor to adjust temperature or humidity, it not only adjusts its speed in a timely manner according to the magnitude of the temperature difference to reduce the impact on storage conditions within the storage compartment, but also helps to achieve energy-saving control and improve the efficient use of energy.

[0052] The following will provide a detailed description of the variable frequency constant temperature and humidity cigar cabinet and its control method, in conjunction with the accompanying drawings and specific embodiments.

[0053] Please see Figure 1 The first aspect of this application provides a control method for a variable frequency constant temperature and humidity cigar cabinet, wherein the variable frequency constant temperature and humidity cigar cabinet includes a compartment for storing cigars, and the control method includes:

[0054] Step S1: Obtain the ambient temperature of the variable frequency constant temperature and humidity cigar cabinet and the internal temperature of the variable frequency constant temperature and humidity cigar cabinet compartment.

[0055] In this embodiment, by acquiring the internal temperature, the storage conditions inside the compartment can be adjusted in a timely manner to meet storage requirements. At the same time, by acquiring the ambient temperature, the temperature inside the compartment can be adjusted based on the ambient temperature, which helps to reduce the impact of the ambient temperature on the internal temperature of the compartment and improve adjustment efficiency.

[0056] Step S2: Compare the ambient temperature with the set temperature, and compare the internal temperature with the set temperature.

[0057] In this embodiment, when the variable frequency constant temperature and humidity cigar cabinet starts to run, the temperature and humidity inside the compartment need to be set according to the storage conditions of the cigars. This allows the temperature and humidity inside the compartment of the variable frequency constant temperature and humidity cigar cabinet to be adjusted with reference to the set temperature and humidity during the adjustment process, so as to meet the storage requirements of the cigars.

[0058] Step S3: In response to the ambient temperature being lower than the set temperature and the internal temperature being lower than the set temperature, the room is heated using a heating device.

[0059] In this embodiment, when the ambient temperature is lower than the set temperature, it indicates that the temperature of the environment in which the variable frequency constant temperature and humidity cigar cabinet is located is low, which easily causes the temperature inside the compartment to drop. When the internal temperature of the compartment is also detected to be lower than the set temperature, a heating device can be used to heat the inside of the compartment to raise the internal temperature to the set temperature, thereby meeting the storage requirements.

[0060] Step S4: Determine whether the variable frequency constant temperature and humidity cigar cabinet has a dehumidification requirement.

[0061] In this embodiment, since the humidity inside the room can easily change during the heating process, the humidity inside the room is monitored in a timely manner during the temperature adjustment process so that the room can be dehumidified in a timely manner when the humidity inside the room exceeds the set humidity.

[0062] Please combine Figure 2 Furthermore, step S4 above can be achieved through the following steps:

[0063] Step S41: Obtain the humidity of the compartment inside the variable frequency constant temperature and humidity cigar cabinet.

[0064] Step S42: Compare the room humidity with the set humidity;

[0065] Step S43: When the humidity in the room is greater than the set humidity, the variable frequency constant temperature and humidity cigar cabinet has a dehumidification requirement.

[0066] In this embodiment, to ensure that the humidity in the storage room meets the storage requirements for cigars, the target conditions in the storage room can be set in advance, i.e., the humidity can be set. At the same time, to ensure that the humidity in the storage room is maintained within a certain range, the humidity in the storage room needs to be detected. When the humidity in the storage room exceeds the set humidity, dehumidification treatment is required.

[0067] Step S5: In response to the dehumidification requirement of the variable frequency constant temperature and humidity cigar cabinet, control the variable frequency compressor to run at the first speed, wherein the magnitude of the first speed is proportional to the absolute value of the difference between the ambient temperature and the set temperature.

[0068] In this embodiment, when dehumidification is required inside the room during the heating process, the inverter compressor can be controlled to operate at a first speed to perform dehumidification. Simultaneously, the larger the absolute value of the difference between the ambient temperature and the set temperature, the greater the temperature difference, meaning a longer heating time is required, leading to greater humidity changes. Therefore, by making the first speed proportional to the absolute value of the difference between the ambient temperature and the set temperature, the first speed can be adjusted according to changes in humidity inside the room. This allows the inverter compressor to operate at high speed and high dehumidification efficiency when humidity changes significantly, and at low speed and low dehumidification efficiency when humidity changes are small, thereby reducing the impact of the inverter compressor on temperature during dehumidification. Furthermore, by using an inverter compressor and controlling the first speed, dehumidification time can be effectively shortened, thereby reducing the power consumption of the inverter compressor and contributing to energy savings.

[0069] For example, the ambient temperature is T1, the internal temperature is T2, and the set temperature is T:

[0070] When T1 < T and T2 < T, a heating device is needed to heat the room so that T2 rises to T. During temperature adjustment, the humidity in the room will increase with the temperature. Therefore, it is necessary to monitor in real time whether dehumidification is required. When dehumidification is required, the inverter compressor can be run at the first speed N1, and the magnitude of N1 is proportional to the absolute value of T1-T, that is, the larger the absolute value of T1-T, the larger N1 is.

[0071] The variable frequency constant temperature and humidity cigar cabinet control method provided in this embodiment controls the internal temperature of the compartment by combining ambient temperature and internal temperature. This allows for timely adjustment of the internal temperature according to different operating conditions, reducing fluctuations in internal temperature or humidity. Simultaneously, by monitoring humidity changes within the compartment while adjusting the temperature, and promptly addressing humidity variations caused by temperature changes, it helps maintain stable temperature and humidity levels, minimizing fluctuations. Furthermore, the use of a variable frequency compressor contributes to energy savings.

[0072] It is worth noting that the proportionality between the magnitude of the first rotational speed and the absolute value of the difference between the ambient temperature and the set temperature can be either continuous or discrete. For example, it can be stipulated that the absolute value of the difference between the ambient temperature and the set temperature within a first range corresponds to one first rotational speed; the absolute value of the difference between the ambient temperature and the set temperature within a second range corresponds to another first rotational speed. Furthermore, the value within the second range is greater than the value within the first range, and the first rotational speed corresponding to the second range is greater than the first rotational speed corresponding to the first range, and so on. In this case, the magnitude of the first rotational speed is discretely proportional to the absolute value of the difference between the ambient temperature and the set temperature. Alternatively, the magnitude of the first rotational speed can be continuously proportional to the absolute value of the difference between the ambient temperature and the set temperature, meaning that each absolute value of the difference between the ambient temperature and the set temperature can correspond to one first rotational speed. In this embodiment, the proportionality relationship is not specifically limited.

[0073] Please see Figure 3 Furthermore, the control method for the variable frequency constant temperature and humidity cigar cabinet provided in this embodiment also includes:

[0074] Step S6: In response to the ambient temperature being greater than the set temperature and the internal temperature being greater than the set temperature, control the variable frequency compressor to run at a second speed, wherein the magnitude of the second speed is proportional to the absolute value of the difference between the ambient temperature and the set temperature.

[0075] In this embodiment, when the ambient temperature is higher than the set temperature, it indicates that the variable frequency constant temperature and humidity cigar cabinet is in a high-temperature environment, and the high external temperature can easily cause the internal temperature of the cabinet to gradually rise. When the internal temperature of the cabinet also exceeds the set temperature, a cooling mechanism is triggered, requiring the variable frequency compressor to operate at its second speed to achieve cooling. Simultaneously, the larger the absolute value of the difference between the ambient temperature and the set temperature, the greater the temperature difference, meaning a longer cooling time is required. Prolonged cooling may lead to changes in humidity. Therefore, by making the second speed proportional to the absolute value of the difference between the ambient temperature and the set temperature, the variable frequency compressor can cool down quickly, thereby reducing the impact on humidity.

[0076] For example, the ambient temperature is T1, the internal temperature is T2, and the set temperature is T:

[0077] When T1 > T and T2 > T, the variable frequency compressor needs to cool the room to reduce T2 to T. During temperature adjustment, the humidity inside the room is affected by the operating time of the variable frequency compressor; the longer the compressor operates, the greater its impact on humidity. Therefore, to minimize the compressor's operating time, it can be operated at a second speed N2, where N2 is directly proportional to the absolute value of T1 - T; that is, the larger the absolute value of T1 - T, the larger N2.

[0078] It is worth noting that the relationship between the magnitude of the second rotational speed and the absolute value of the difference between the ambient temperature and the set temperature can be a continuous proportional relationship or a discrete proportional relationship. This can be referred to the explanation of the first rotational speed above, and will not be repeated here.

[0079] Specifically, the control method for the variable frequency constant temperature and humidity cigar cabinet provided in this embodiment further includes the following after step S6:

[0080] Step S7: In response to the difference between the internal temperature and the set temperature exceeding the first threshold, control the variable frequency compressor to run at a third speed; wherein the third speed is greater than the second speed, and the magnitude of the third speed is proportional to the absolute value of the difference between the internal temperature and the set temperature.

[0081] In this embodiment, considering that when the difference between the internal temperature and the set temperature is large, it is necessary to cool the compartment as quickly as possible. Therefore, when the difference between the internal temperature and the set temperature exceeds a first threshold, the variable frequency compressor can be controlled to operate at a third speed. At this time, the third speed is greater than the second speed in step S6, and the second speed in step S6 corresponds to a difference between the internal temperature and the set temperature that does not exceed the first threshold. Simultaneously, since a larger absolute value of the difference between the internal temperature and the set temperature indicates a larger temperature difference, meaning a longer cooling time is required, prolonged cooling may lead to changes in humidity. Therefore, by making the third speed proportional to the absolute value of the difference between the ambient temperature and the set temperature, the variable frequency compressor can cool down quickly, thereby reducing the impact on humidity.

[0082] It is worth noting that the relationship between the magnitude of the third rotational speed and the absolute value of the difference between the internal temperature and the set temperature can be a continuous or discrete proportional relationship. This can be referred to the explanation of the first rotational speed above, and will not be repeated here.

[0083] For example, the ambient temperature is T1, the internal temperature is T2, and the set temperature is T:

[0084] When T1 > T and T2 > T, a variable frequency compressor is needed to cool the room so that T2 is reduced to T.

[0085] When T2-T≥a, a is the first threshold. At this point, the difference between the internal temperature T2 and the set temperature T is too large, and it needs to be adjusted to the set temperature T as soon as possible. Therefore, in order to minimize the working time of the variable frequency compressor, the variable frequency compressor can be operated at the third speed N3, where N3>N2, and N... ,3 The magnitude of N3 is directly proportional to the absolute value of T2-T; that is, the larger the absolute value of T2-T, the larger N3 is.

[0086] In some embodiments, the control method for the variable frequency constant temperature and humidity cigar cabinet further includes:

[0087] Step S8: In response to the internal temperature being equal to the set temperature, determine whether the variable frequency constant temperature and humidity cigar cabinet has a dehumidification requirement.

[0088] In this embodiment, if the internal temperature equals the set temperature, no temperature adjustment is required. However, it is still necessary to monitor whether the humidity inside the room meets the requirements to maintain the storage conditions within the room.

[0089] Furthermore, the determination of whether the variable frequency constant temperature and humidity cigar cabinet has a dehumidification requirement in step S8 can be referred to steps S41 to S43, which will not be repeated here.

[0090] Step S9: In response to the dehumidification requirement of the variable frequency constant temperature and humidity cigar cabinet, control the variable frequency compressor to run at the fourth speed.

[0091] In this embodiment, when there is a need for dehumidification, the inverter compressor needs to be controlled to run at the fourth speed to achieve the dehumidification function and adjust the humidity in the room.

[0092] Specifically, in order to reduce the humidity of the room to the set humidity in a shorter time, the magnitude of the fourth rotation speed can be proportional to the absolute value of the difference between the room humidity and the set humidity, so as to improve the dehumidification efficiency.

[0093] For example, the room humidity is H1, and the set humidity is H:

[0094] When H1 > H, the inverter compressor needs to dehumidify the room to reduce H1 to H. During humidity adjustment, the room temperature is affected by the operating time of the inverter compressor; the longer the compressor operates, the greater its impact on the room temperature. Therefore, to minimize the compressor's operating time, it can be operated at a fourth speed N4, where N4 is directly proportional to the absolute value of H1 - H; that is, the larger the absolute value of H1 - H, the larger N4.

[0095] It is worth noting that the relationship between the magnitude of the fourth rotation speed and the absolute value of the difference between the room humidity and the set humidity can be a continuous or a discrete proportional relationship. This can be referred to the explanation of the first rotation speed above, and will not be repeated here.

[0096] In some embodiments, after step S8 described above, the control method for the variable frequency constant temperature and humidity cigar cabinet further includes:

[0097] Step S10: In response to the fact that the variable frequency constant temperature and humidity cigar cabinet does not have a dehumidification requirement, the variable frequency compressor is turned off.

[0098] In this embodiment, when cooling and dehumidifying the room is not required, the inverter compressor can be turned off, thereby effectively saving energy and reducing energy consumption.

[0099] This means that after steps S6 and S7 above, the humidity in the room needs to be detected. If the humidity does not meet the requirements when the temperature is adjusted to a stable value, the humidity in the room can be adjusted by the operation of steps S8 to S10.

[0100] It is understandable that when it is necessary to humidify the room, the humidification device can be activated. In this embodiment, the specific humidification method is not limited.

[0101] Please see Figure 4The second aspect of this embodiment provides a variable frequency constant temperature and humidity cigar cabinet 200, which includes a humidification device 201, a refrigeration / dehumidification device 202, a heating device 203, and a temperature and humidity control device 204. The refrigeration / dehumidification device 202 includes a variable frequency compressor 2021, an evaporator 2022, and a condensation and heat dissipation device 2023. The temperature and humidity control device 204 includes an ambient temperature sensor 2041, a room temperature sensor 2042, a room humidity sensor 2043, and a controller 2044. The humidification device 201 is used to humidify the compartment; the cooling / dehumidification device 202 is used to cool or dehumidify the compartment; the heating device 203 is used to heat the compartment; the ambient temperature sensor 2041, the compartment temperature sensor 2042, and the compartment humidity sensor 2043 are used to detect the ambient temperature, the internal temperature, and the internal humidity, respectively; the controller 2044 is used to control the humidification device 201, the cooling / dehumidification device 202, and the heating device 203 based on the detection data from the ambient temperature sensor 2041, the compartment temperature sensor 2042, and the compartment humidity sensor 2043. That is, the controller 2044 controls the cigar cabinet 200 according to the control method described in the first aspect above, so that the temperature and humidity inside the cigar cabinet compartment are maintained at a stable value. At the same time, by taking into account the impact of ambient temperature and humidity on the temperature and humidity inside the cigar cabinet, the storage environment inside the cabinet can be adjusted in a timely manner and kept in a stable state. This avoids the situation where, when only focusing on the internal environmental conditions of the cabinet, the adjustment process is very long or prone to fluctuations due to the influence of the external environment while the internal environmental conditions are being met to meet storage requirements.

[0102] Meanwhile, this embodiment uses a variable frequency compressor 2021 to adjust the temperature or humidity. It can not only adjust the speed in a timely manner according to the absolute value of the temperature difference to reduce the impact on the storage conditions in the room, but also help to achieve energy-saving control and improve the effective use of energy.

[0103] It is understood that the humidification device 201 and heating device 203 mentioned above can be commonly used humidification or heating structures on the market, such as water tanks, electric heaters, etc. In this embodiment, the specific composition of the above devices is not limited.

[0104] Furthermore, the variable frequency constant temperature and humidity cigar cabinet 200 provided in this embodiment also includes a heat preservation device 205. That is, when the temperature inside the room is maintained at the condition that meets the storage requirements, the heat preservation device 205 can be used to keep the inside of the room warm, thereby avoiding the continuous operation of the heating device 203 or the cooling / dehumidification device 202, thus effectively saving energy resources and achieving energy-saving protection.

[0105] It is understood that the above-mentioned insulation device 205 can be insulation foam, insulation polystyrene board, or other insulation materials, or insulation device 205 can be insulation equipment, etc. In this embodiment, the specific structure of insulation device 205 is not limited.

[0106] In some embodiments, in order to further improve the stability of temperature and humidity inside the room of the variable frequency constant temperature and humidity cigar cabinet 200, it also includes an air circulation device 206, which uses the air circulation device 206 to circulate the air inside the room so that the temperature and humidity of each position inside the room are uniform, avoiding different temperatures or humidity in different positions, which would affect the detection results of each sensor and make it difficult to control the storage conditions inside the room.

[0107] The aforementioned air circulation device 206 may include a fan to circulate air within the room. In other embodiments, the air circulation device 206 may also include ventilation ducts to effectively circulate air within the room and quickly and evenly distribute temperature and humidity in different areas. It is understood that the air circulation device 206 may have different structures in other embodiments, and this embodiment does not limit the air circulation device 206.
