[0033] The following describes in detail embodiments of the present disclosure, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0034] A dehumidifier is a household appliance that separates excess water vapor from the air, reducing the water vapor content in the air, and thus regulating and controlling the humidity of the air. Currently, a set dehumidification time is usually adopted. Within the set time, continuous dehumidification is performed by controlling the compressor to run continuously, thereby reducing the water vapor content in the air and improving user comfort. However, continuous dehumidification can easily lead to compressor overload and high energy consumption. In addition, some dehumidifiers can also perform intelligent dehumidification according to temperature, but cannot achieve automatic energy-saving dehumidification, and are only controlled based on the temperature as a single factor, and the dehumidification is not user-friendly. To this end, the present disclosure proposes a dehumidification control method, which obtains the indoor ambient temperature and indoor ambient humidity, then determines the target humidity based on the indoor ambient temperature, and determines the humidity difference between the indoor ambient humidity and the target humidity. Finally, the fan speed and compressor frequency of the dehumidifier are controlled according to the humidity difference, which can avoid the compressor from running for a long time, thereby improving the energy-saving effect of the dehumidifier.

[0035] The following describes a dehumidification control method, a computer-readable storage medium, a dehumidification controller, and a dehumidification device proposed in embodiments of the present disclosure with reference to the accompanying drawings.

[0036] FIG1 is a flow chart of a dehumidification control method according to an embodiment of the present disclosure.

[0037] As shown in FIG1 , the dehumidification control method according to an embodiment of the present disclosure may include the following steps:

[0038] S1, obtain indoor ambient temperature and indoor ambient humidity.

[0039] S2, determining a target humidity according to the indoor ambient temperature, and determining a humidity difference between the indoor ambient humidity and the target humidity.

[0040] S3, controlling the fan speed and compressor frequency of the dehumidification equipment according to the humidity difference.

[0041] Specifically, when a dehumidifier is dehumidifying a room, the current indoor ambient temperature and humidity can be obtained in order to determine the dehumidifier's operating characteristics, such as the fan speed and compressor speed. For example, the indoor ambient temperature can be obtained using a temperature sensor installed indoors, and the indoor ambient humidity can be obtained using a humidity sensor installed indoors. Thus, obtaining the indoor ambient temperature and humidity using a temperature sensor and a humidity sensor can improve the efficiency and accuracy of obtaining the indoor ambient temperature and humidity.

[0042] Different indoor ambient temperatures correspond to different target humidity levels. After obtaining the indoor ambient temperature, the corresponding target humidity can be determined based on the indoor ambient temperature. This means that the dehumidifier can determine the target humidity based on the current indoor ambient temperature, maintaining the indoor environment at a certain humidity level and providing a better user experience. Different target humidity levels can be set based on the human body's different perceptions of humidity at different temperatures. For example, at an ambient temperature of 26 degrees Celsius, user A may be more comfortable at 60% RH (Relative Humidity), while user B may be more comfortable at 55% RH. Therefore, the target humidity can be determined based on actual conditions.

[0043] After determining the target humidity, the humidity difference between the indoor environment humidity and the target humidity can be determined. It can be understood that determining the humidity difference between the indoor environment humidity and the target humidity means determining the difference between the relatively higher one of the indoor environment humidity and the target humidity minus the relatively lower one, that is, when the indoor environment humidity is greater than the target humidity, the humidity difference between the indoor environment humidity and the target humidity is the difference between the indoor environment humidity and the target humidity minus the target humidity; when the indoor environment humidity is less than the target humidity, the humidity difference between the indoor environment humidity and the target humidity is the difference between the target humidity and the indoor environment humidity.

[0044] In order to make people feel comfortable while also enabling the dehumidifier to operate in a more energy-efficient state, the dehumidifier can automatically optimize its operation based on the humidity difference between the indoor ambient humidity and the target humidity. That is, the dehumidifier's fan speed and compressor frequency can be controlled based on the humidity difference. For example, when the temperature difference is large, such as when the difference between the current indoor ambient humidity and the target humidity is large, the dehumidifier's fan can be controlled to run at a higher speed and the dehumidifier's compressor can be controlled to run at a higher frequency, so that the indoor ambient humidity can be reduced to the target humidity as quickly as possible to improve user comfort. When the temperature difference is small, such as when the difference between the current indoor ambient humidity and the target humidity is small, the dehumidifier's fan can be controlled to run at a lower speed and the dehumidifier's compressor can be controlled to run at a lower frequency, so that the dehumidifier can operate more energy-efficiently. In addition, if the indoor ambient humidity is lower than the target humidity, it means that the current indoor humidity is low and there is no need to control the dehumidifier to continue dehumidifying according to the target humidity. The dehumidifier's fan and compressor can be controlled to stop to achieve the purpose of energy saving.

[0045] Therefore, by determining the target humidity according to the indoor ambient temperature and controlling the fan speed and compressor frequency of the dehumidification equipment according to the humidity difference between the indoor ambient humidity and the target humidity, the compressor can be prevented from running for a long time, thereby improving the energy-saving effect of the dehumidification equipment.

[0046] The specific working process of the dehumidification control method disclosed in the present invention is described in detail below.

[0047] According to one embodiment of the present disclosure, determining a target humidity based on an indoor ambient temperature includes: determining a temperature range within which the indoor ambient temperature falls; and determining a corresponding target humidity based on the temperature range within which the indoor ambient temperature falls. The target humidity is inversely correlated with the indoor ambient temperature.

[0048] Specifically, when determining the target humidity based on the indoor ambient temperature, the temperature range of the indoor environment can be determined first. For example, multiple temperature ranges can be divided, such as a high temperature range, a medium temperature range, and a low temperature range. For example, an indoor ambient temperature above 30 degrees can be considered to be in the high temperature range, an indoor ambient temperature between 15 degrees and 30 degrees can be considered to be in the medium temperature range, and an indoor ambient temperature below 15 degrees can be considered to be in the low temperature range. In this way, the temperature range can be determined based on the indoor ambient temperature.

[0049] After determining the temperature range of the indoor ambient temperature, the corresponding target humidity can be determined based on the temperature range of the indoor ambient temperature. For example, a table can be used to store multiple temperature ranges and target humidity values ​​in a temperature range-target humidity table. Different temperature ranges correspond to different target humidity values, and there is a one-to-one correspondence between temperature ranges and target humidity. Once a temperature range is determined, the corresponding target humidity can be determined. For example, the target humidity corresponding to the high temperature range is 50% RH, the target humidity corresponding to the medium temperature range is 55% RH, and the target humidity corresponding to the low temperature range is 60% RH.

[0050] It should be noted that the target humidity is inversely correlated with the indoor ambient temperature. That is, the higher the current indoor ambient temperature, the lower the target humidity, and the lower the current indoor ambient temperature, the higher the target humidity. In high-temperature and high-humidity environments, people are more likely to suffer serious consequences such as heatstroke or heat exhaustion. Therefore, when the indoor temperature is high, the target humidity should be lowered compared to when the indoor temperature is low. This allows for a more reasonable target humidity setting.

[0051] Furthermore, according to an embodiment of the present disclosure, determining a corresponding target humidity based on the temperature range of the indoor ambient temperature includes: when the indoor ambient temperature is greater than a first preset temperature, determining a first set humidity as the target humidity; when the indoor ambient temperature is less than or equal to a second preset temperature, determining a second set humidity as the target humidity, wherein the second preset temperature is less than the first preset temperature and the second set humidity is greater than the first set humidity; and when the indoor ambient temperature is less than or equal to the first preset temperature and greater than the second preset temperature, determining the target humidity based on the first set humidity, the second set humidity, the indoor ambient temperature, the first preset temperature, and the second preset temperature. The first preset temperature, the second preset temperature, the first set temperature, and the second set temperature may be determined based on actual conditions.

[0052] Specifically, when dividing the temperature intervals, for example, when the indoor ambient temperature is greater than the first preset temperature, it can be determined that the indoor ambient temperature is in the high temperature interval; when the indoor ambient temperature is less than or equal to the second preset ambient temperature, it can be determined that the indoor ambient temperature is in the low temperature interval; when the indoor ambient temperature is less than the first preset temperature and greater than the second preset temperature, it can be determined that the indoor ambient temperature is in the medium temperature interval. Therefore, when determining the corresponding target humidity according to the temperature interval in which the indoor ambient temperature is located, the indoor ambient temperature can first be compared with the first preset temperature. When the indoor ambient temperature is greater than the first preset temperature, the first set humidity can be determined as the target humidity. For example, the first preset temperature can be set to 25 degrees and the first set humidity can be set to 45% RH. If the current indoor temperature measured by the indoor temperature sensor is 30 degrees, which is 25 degrees higher than the first preset temperature, the target humidity can be set to 45% RH.

[0053] The indoor ambient temperature is compared with the second preset temperature. When the indoor ambient temperature is less than or equal to the second preset temperature, the second set humidity can be determined as the target humidity. For example, the second preset temperature can be set to 15 degrees and the second set humidity is 65% RH. If the current indoor temperature measured by the indoor temperature sensor is 13 degrees, which is 15 degrees lower than the second preset temperature, the target humidity can be set to 65% RH.

[0054] After comparing the indoor ambient temperature with the first preset temperature and the second preset temperature, if the indoor ambient temperature is less than or equal to the first preset temperature and the indoor ambient temperature is greater than the second preset temperature, the target humidity can be determined based on the first set humidity, the second set humidity, the indoor ambient temperature, the first preset temperature, and the second preset temperature. For example, the formula can be: target humidity = (second set humidity - first set humidity) / (first preset temperature - second preset temperature) * (indoor ambient temperature - second preset temperature) + first set humidity. For example, the current indoor temperature measured by the indoor temperature sensor is 20 degrees, the first preset temperature is 25 degrees, the first set humidity is 45% RH, the second preset temperature is 15 degrees, and the second set humidity is 65% RH. After calculation with the above formula, the target humidity can be determined to be 55 ((65-45) / (25-15)*(20-15)+45)% RH. Therefore, when the indoor ambient temperature is less than or equal to the first preset temperature and greater than the second preset temperature, the target humidity is determined by the first set humidity, the second set humidity, the indoor ambient temperature, the first preset temperature and the second preset temperature, so that the target humidity is not a fixed value and is more diverse, so as to bring better comfort to the user.

[0055] It should be noted that the first and second humidity settings can be adaptively adjusted based on the needs of different groups of people. For example, the first humidity setting of 45% RH can be adjusted higher or lower based on the humidity sensitivity of different groups of people, and the second humidity setting of 65% RH can be adjusted higher or lower based on the humidity sensitivity of different groups of people. In addition, when the indoor temperature is high, the target humidity can be lowered, and when the indoor temperature is low, the target humidity can be higher, thereby providing users with a more comfortable experience.

[0056] According to an embodiment of the present disclosure, before determining the humidity difference between the indoor environment humidity and the target humidity, the method further includes: adjusting the target humidity in response to a humidity adjustment instruction.

[0057] Specifically, the target humidity can be adjusted according to the perception of humidity by different groups of people and can respond to humidity adjustment instructions. For example, users can adjust the humidity through the physical buttons on the remote control, such as raising the target humidity or lowering the target humidity. Alternatively, they can control the target humidity through smart devices connected to the dehumidification equipment, such as applications on mobile phones and tablets.

[0058] For example, if the current indoor temperature measured by the indoor temperature sensor is 30 degrees, 25 degrees higher than the first preset temperature, the target humidity is set to 45% RH. This target humidity may be the most comfortable humidity value for the previous user. If other users feel that the current humidity value is still relatively humid, the target humidity can be lowered, such as setting it to 42% RH. For another example, if the current indoor temperature measured by the indoor temperature sensor is 13 degrees, 15 degrees lower than the second preset temperature, the target humidity is set to 65% RH. If the user feels that the environment is still relatively dry, the target humidity can be raised, such as setting it to 68% RH. In this way, by adjusting the target humidity, the needs of different groups of people can be met, making it more humane.

[0059] According to one embodiment of the present disclosure, controlling the fan speed and compressor frequency of a dehumidifier based on a humidity difference includes: determining a humidity configuration interval within which the humidity difference falls; determining a corresponding fan speed and compressor frequency based on the humidity configuration interval within which the humidity difference falls; and controlling the fan and compressor in the dehumidifier to operate at the corresponding fan speed and compressor frequency. The fan speed and compressor frequency are positively correlated with the humidity difference.

[0060] Specifically, after calculating the humidity difference between the indoor ambient humidity and the target humidity, the humidity configuration interval in which the humidity difference lies can be determined. For example, the humidity configuration interval can be divided into three, such as a high humidity configuration interval, a medium humidity configuration interval, and a low humidity configuration interval. Different humidity configuration intervals can be determined based on different humidity differences. For example, when the humidity difference is 20%, the humidity difference can be determined to be in the high humidity configuration interval; when the humidity difference is 10%, the humidity difference can be determined to be in the medium humidity configuration interval; and when the humidity difference is 5%, the humidity difference can be determined to be in the low humidity configuration interval.

[0061] After determining the humidity configuration interval, the corresponding fan speed and compressor frequency can be determined based on the humidity configuration interval in which the difference value falls, thereby controlling the fan and compressor in the dehumidification equipment to operate according to the corresponding fan speed and compressor frequency. For example, a table lookup method can be used, such as a table of humidity configuration interval-fan speed-compressor frequency, which stores multiple humidity configuration intervals and fan speed and compressor frequency values. Different humidity configuration intervals correspond to different fan speeds and compressor frequencies, and there is a one-to-one correspondence between humidity configuration intervals and fan speeds, and a one-to-one correspondence between humidity configuration intervals and compressor frequencies. When a humidity configuration interval is determined, the corresponding fan speed and compressor frequency can be determined.

[0062] It should be noted that the fan speed and compressor frequency are positively correlated with the humidity difference, that is, when the temperature difference is larger, the fan can be controlled to run at a higher speed, and the compressor can be controlled to run at a higher frequency, so that the dehumidification equipment can quickly reduce the humidity difference after running at a higher fan speed and compressor frequency, giving the user a better experience. When the temperature difference is smaller, the fan can be controlled to run at a lower speed, and the compressor can be controlled to run at a lower frequency, so that the dehumidification equipment can run at a lower fan speed and compressor frequency to achieve the purpose of energy saving.

[0063] According to one embodiment of the present disclosure, the corresponding fan speed and compressor frequency are determined according to the humidity configuration interval in which the humidity difference is located, including: when the humidity difference is greater than or equal to a first preset humidity threshold, determining the first fan speed as the target operating speed of the fan, and determining the first compressor frequency as the target operating frequency of the compressor; when the humidity difference is less than the first preset humidity threshold and greater than or equal to the second preset humidity threshold, determining the second fan speed and the second compressor frequency, and determining the target operating speed of the fan according to the first fan speed, the second fan speed, the humidity difference, the first preset humidity threshold and the second preset humidity threshold, and determining the first compressor frequency according to the first compressor frequency, the second compressor frequency, the humidity difference, the first preset humidity threshold and the second preset humidity threshold. The target operating frequency of the compressor is determined based on the second preset humidity threshold, wherein the second fan speed is less than the first fan speed and the second compressor frequency is less than the first compressor frequency. When the humidity difference is less than the second preset humidity threshold and greater than or equal to the third preset humidity threshold, a third fan speed and a third compressor frequency are determined. The target operating speed of the fan is determined based on the second fan speed, the third fan speed, the humidity difference, the second preset humidity threshold, and the third preset humidity threshold. The target operating frequency of the compressor is determined based on the second compressor frequency, the third compressor frequency, the humidity difference, the second preset humidity threshold, and the third preset humidity threshold. The third fan speed is less than the second fan speed and the third compressor frequency is less than the second compressor frequency. The first preset humidity threshold, the second preset humidity threshold, the third preset humidity threshold, the first fan speed, the second fan speed, the third fan speed, the first compressor frequency, the second compressor frequency, and the third compressor frequency can be determined based on actual conditions.

[0064] Specifically, when dividing the humidity configuration intervals, for example, when the humidity difference is greater than or equal to a first preset humidity threshold, the humidity difference can be determined to be in a high humidity configuration interval; when the humidity difference is less than the first preset humidity threshold and greater than or equal to a second preset humidity threshold, the humidity difference can be determined to be in a medium humidity configuration interval; and when the humidity difference is less than the second preset humidity threshold, the humidity difference can be determined to be in a low humidity configuration interval. When determining the corresponding fan speed and compressor frequency based on the humidity configuration interval in which the humidity difference is located, the humidity difference can first be compared with the first preset humidity threshold. When the humidity difference is greater than or equal to the first preset humidity threshold, it indicates that the difference between the indoor humidity and the target humidity is too large. The first fan speed can be determined as the target operating speed of the fan, and the first compressor frequency can be determined as the target operating frequency of the compressor. For example, the table lookup method can be used to determine the first fan speed as Spd1 and the first compressor frequency as F1 according to the humidity difference, and the first preset humidity threshold is 15% RH. For example, the current indoor humidity measured by the indoor humidity sensor is 60% RH, and the target humidity is 45% RH. After calculation, the difference between the indoor humidity and the target humidity is 15% RH, which is equal to the first preset humidity threshold 15% RH. Therefore, the target operating speed of the fan can be controlled to Spd1, and the target compressor frequency can be controlled to F1. That is, the dehumidification equipment operates at a higher fan speed and compressor frequency, so that the difference between the indoor humidity and the target humidity can be quickly reduced, which can quickly reduce the indoor humidity and improve the user's comfort.

[0065] The temperature difference is compared with a first preset humidity threshold and a second preset humidity threshold. When the humidity difference is less than the first preset humidity threshold and greater than or equal to the second preset humidity threshold, it indicates that the difference between the indoor humidity and the target humidity is significant. A second fan speed and a second compressor frequency can be determined. For example, the second fan speed can be determined as Spd2 and the second compressor frequency can be determined as F2 based on the humidity difference using a table lookup. After determining the second fan speed and the second compressor frequency, a target fan speed can be determined based on the first fan speed, the second fan speed, the humidity difference, the first preset humidity threshold, and the second preset humidity threshold. Furthermore, a target compressor frequency can be determined based on the first compressor frequency, the second compressor frequency, the humidity difference, the first preset humidity threshold, and the second preset humidity threshold. For example, the target fan speed can be determined based on the formula: target speed = (first fan speed - second fan speed) * (temperature difference - second preset temperature threshold) / (first preset humidity threshold - second preset humidity threshold) + second fan speed. The target operating frequency of the compressor can be determined according to the formula: target operating frequency = (first compressor frequency - second compressor frequency) * (temperature difference - second preset temperature threshold) / (first preset humidity threshold - second preset humidity threshold) + second compressor frequency.

[0066] The humidity difference is compared with the second and third preset humidity thresholds. When the humidity difference is less than the second preset humidity threshold and greater than or equal to the third preset humidity threshold, a third fan speed and a third compressor frequency can be determined. For example, the third fan speed can be determined as Spd3 and the third compressor frequency can be determined as F3 based on the humidity difference using a table lookup. After determining the third fan speed and the third compressor frequency, a target fan speed can be determined based on the second and third fan speeds, the humidity difference, the second and third preset humidity thresholds, and a target compressor frequency can be determined based on the second and third compressor frequencies, the humidity difference, the second and third preset humidity thresholds. For example, the target fan speed can be determined based on the formula: target speed = (second fan speed - third fan speed) * (temperature difference - third preset temperature threshold) / (second preset humidity threshold - third preset humidity threshold) + third fan speed. The target operating frequency of the compressor can be determined according to the formula: target operating frequency = (second compressor frequency - third compressor frequency) * (temperature difference - third preset temperature threshold) / (second preset humidity threshold - third preset humidity threshold) + third compressor frequency.

[0067] It should be noted that the first, second, and third compressor frequencies decrease in magnitude, and the first, second, and third fan speeds decrease in magnitude. Furthermore, when changing the compressor frequency and fan speed, the aforementioned formula is used to determine them linearly, rather than adjusting them directly from a higher value to a lower value. This improves comfort and user experience.

[0068] According to an embodiment of the present disclosure, when the humidity difference is less than a third preset humidity threshold, the method further includes: controlling the fan and the compressor to stop respectively.

[0069] Specifically, when comparing the humidity difference with a third preset humidity threshold, if the humidity difference is less than the third preset humidity threshold, the fan and compressor can be controlled to stop to achieve power conservation. For example, if the current indoor humidity is 45% RH, the target humidity is 50% RH, and the humidity difference between the indoor humidity and the target humidity is -5% RH, and if the currently set third preset humidity threshold is 0% RH, then the humidity difference of -5% RH is less than the third preset humidity threshold of 0% RH. This indicates that the current indoor humidity has reached the target humidity and is lower than the target humidity. Therefore, there is no need to control the dehumidification equipment for dehumidification. Instead, the fan and compressor can be controlled to stop separately to achieve energy conservation.

[0070] The control method of the present disclosure is described below with reference to FIG2 .

[0071] As a specific example, the dehumidification control method of the present disclosure may include the following steps:

[0076] S105 , determining the target humidity according to the first set humidity, the second set humidity, the indoor ambient temperature, the first preset temperature and the second preset temperature, and proceeding to step S107 .

[0078] S107, determining whether a humidity adjustment instruction has been received. If yes, proceed to step S108; if not, proceed to step S109.

[0079] S108, adjusting the target humidity.

[0080] S109: Obtain the humidity difference between the indoor environment humidity and the target humidity.

[0081] S110, determining whether the humidity difference is greater than or equal to a first preset humidity threshold. If yes, proceed to step S111; if not, proceed to step S112.

[0083] S112: Determine whether the humidity difference is greater than or equal to a second preset humidity threshold. If yes, go to step S113; if not, go to step S114.

[0084] S113, determine the second fan speed and the second compressor frequency, and determine the target operating speed of the fan based on the first fan speed, the second fan speed, the humidity difference, the first preset humidity threshold and the second preset humidity threshold, and determine the target operating frequency of the compressor based on the first compressor frequency, the second compressor frequency, the humidity difference, the first preset humidity threshold and the second preset humidity threshold.

[0085] S114: Determine whether the humidity difference is greater than or equal to a third preset humidity threshold. If yes, go to step S115; if not, go to step S116.

[0086] S115, determine the third fan speed and the third compressor frequency, and determine the target operating speed of the fan based on the second fan speed, the third fan speed, the humidity difference, the second preset humidity threshold and the third preset humidity threshold, and determine the target operating frequency of the compressor based on the second compressor frequency, the third compressor frequency, the humidity difference, the second preset humidity threshold and the third preset humidity threshold.

[0087] S116, controls the fan and compressor to stop respectively.

[0088] In summary, the dehumidification control method according to the disclosed embodiment first obtains the indoor ambient temperature and indoor ambient humidity, then determines the target humidity based on the indoor ambient temperature, and determines the humidity difference between the indoor ambient humidity and the target humidity. Finally, the fan speed and compressor frequency of the dehumidifier are controlled based on the humidity difference.
