[0029] Embodiments of the present invention are described in detail below, 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 invention, and should not be construed as limiting the present invention.

[0030] Dehumidification equipment is a household appliance that separates excess water vapor from the air and reduces the content of water vapor in the air, thereby regulating and controlling the humidity of the air. At present, the dehumidification time is usually set. Within the set time, the compressor is controlled to continue to run to continuously dehumidify, thereby reducing the content of water vapor in the air and improving user comfort. However, continuous dehumidification can easily lead to overload operation of the compressor and high energy consumption. In addition, some dehumidification equipment can also perform intelligent dehumidification according to temperature, but it is impossible to achieve automatic energy-saving dehumidification, and it is only controlled based on the temperature as a single factor, and it is not user-friendly when dehumidifying. To this end, the present invention proposes a dehumidification control method, which obtains the indoor environment temperature and the indoor environment humidity, and then determines the target humidity according to the indoor environment temperature, and determines the humidity difference between the indoor environment humidity and the target humidity. Finally, the fan speed and compressor frequency of the dehumidification equipment 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 dehumidification equipment.

[0031] The dehumidification control method, computer-readable storage medium, dehumidification controller and dehumidification device proposed in the embodiments of the present invention are described below with reference to the accompanying drawings.

[0032] Figure 1 4 is a flow chart of a dehumidification control method according to an embodiment of the present invention.

[0033] like Figure 1 As shown, the dehumidification control method of the embodiment of the present invention may include the following steps:

[0034] S1, obtaining indoor ambient temperature and indoor ambient humidity.

[0035] 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.

[0036] S3, controlling the fan speed and compressor frequency of the dehumidification equipment according to the humidity difference.

[0037] Specifically, when the dehumidification device is dehumidifying the room, in order to determine the characteristics of the dehumidification device when it is working, such as determining the fan speed and compressor speed of the dehumidification device when it is dehumidifying, the current indoor ambient temperature and indoor ambient humidity can be obtained first. For example, the indoor ambient temperature can be obtained through a temperature sensor installed indoors, and the indoor ambient humidity can be obtained through a humidity sensor installed indoors. In this way, obtaining the indoor ambient temperature through a temperature sensor and obtaining the indoor ambient humidity through a humidity sensor can improve the efficiency and accuracy of obtaining the indoor ambient temperature and the indoor ambient humidity.

[0038] Different indoor ambient temperatures correspond to different target humidities. After obtaining the indoor ambient temperature, the corresponding target humidity can be determined according to the indoor ambient temperature, that is, the dehumidification equipment can determine the target humidity according to the current indoor ambient temperature, so that the indoor environment is maintained at a certain humidity, giving users a better experience. Among them, different target humidities can be set according to the different perceptions of the human body to different humidities at different temperatures. For example, at an ambient temperature of 26 degrees, user A feels more comfortable with 60% RH (Relative Humidity), while user B feels more comfortable with 55% RH. Therefore, the target humidity can be set according to the actual situation.

[0039] 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, and 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.

[0040] In order to make the human body feel comfortable, the dehumidification equipment can also be operated in a more energy-saving state. It can automatically optimize the operation according to the humidity difference between the indoor environment humidity and the target humidity, that is, the fan speed and compressor frequency of the dehumidification equipment can be controlled according to the humidity difference. For example, when the temperature difference is large, such as when the difference between the current indoor environment humidity and the target humidity is large, the fan of the dehumidification equipment can be controlled to run at a higher speed and the compressor of the dehumidification equipment can be controlled to run at a higher frequency, so that the indoor environment humidity can be reduced to the target humidity as soon as possible to improve the user's comfort. When the temperature difference is small, such as when the difference between the current indoor environment humidity and the target humidity is small, the fan of the dehumidification equipment can be controlled to run at a lower speed and the compressor of the dehumidification equipment can be controlled to run at a lower frequency, so that the dehumidification equipment can be operated more energy-saving. In addition, if the indoor environment humidity is lower than the target humidity, it means that the current indoor humidity is low, and there is no need to control the dehumidification equipment to continue to dehumidify according to the target humidity. The fan and compressor of the dehumidification can be controlled to stop to achieve the purpose of energy saving.

[0041] 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, it is possible to avoid the compressor from running for a long time, thereby improving the energy saving effect of the dehumidification equipment.

[0042] The specific working process of the dehumidification control method of the present invention is described in detail below.

[0043] According to an embodiment of the present invention, determining the target humidity according to the indoor ambient temperature includes: determining the temperature interval of the indoor ambient temperature; and determining the corresponding target humidity according to the temperature interval of the indoor ambient temperature. The target humidity is inversely correlated with the indoor ambient temperature.

[0044] Specifically, when determining the target humidity according to 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, a low temperature range, etc. For example, an indoor ambient temperature higher than 30 degrees can be considered to be in a high temperature range, an indoor ambient temperature between 15 degrees and 30 degrees can be considered to be in a medium temperature range, and an indoor ambient temperature lower than 15 degrees can be considered to be in a low temperature range. Thus, the temperature range can be determined according to the indoor ambient temperature.

[0045] After determining the temperature range of the indoor ambient temperature, the corresponding target humidity can be determined according to the temperature range of the indoor ambient temperature. For example, a table lookup method can be used. For example, in the temperature range-target humidity table, multiple temperature ranges and target humidity values ​​are stored. Different temperature ranges correspond to different target humidity, and the temperature range and target humidity are in a one-to-one correspondence. When 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.

[0046] 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 other words, in a high temperature and high humidity environment, people are more likely to suffer from serious consequences such as heat stroke or heat exhaustion. Therefore, when the indoor temperature is high, the target humidity is lower than when the indoor temperature is low, so that the target humidity can be set more reasonably.

[0047] Further, according to an embodiment of the present invention, the corresponding target humidity is determined according to the temperature range of the indoor ambient temperature, including: when the indoor ambient temperature is greater than the first preset temperature, the first set humidity is determined as the target humidity; when the indoor ambient temperature is less than or equal to the second preset temperature, the second set humidity is determined 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; 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 according to 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 can be determined according to actual conditions.

[0048] Specifically, when dividing the temperature interval, 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, and 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 be compared with the first preset temperature first. 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 is 45% RH. If the current indoor temperature is measured by the indoor temperature sensor and the temperature value is 30 degrees, which is 25 degrees higher than the first preset temperature, the target humidity can be set to 45% RH.

[0049] 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.

[0050] 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 according to the first set humidity, the second set humidity, the indoor ambient temperature, the first preset temperature and the second preset temperature. For example, the target humidity can be determined by the formula: (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 by 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 but more diverse, so as to bring better comfort to the user.

[0051] It should be noted that the first set humidity and the second set humidity can be adaptively adjusted according to the needs of different groups of people. For example, the first set humidity of 45% RH can be adjusted higher or lower according to the sensitivity of different groups of people to humidity, and the second set humidity of 65% RH can be adjusted higher or lower according to the sensitivity of different groups of people to humidity. In addition, when the indoor temperature is high, the target humidity can be lowered, and when the indoor ambient temperature is low, the target humidity can be higher, thereby giving users a more comfortable experience.

[0052] According to an embodiment of the present invention, before determining the humidity difference between the indoor environment humidity and the target humidity, the method further comprises: adjusting the target humidity in response to a humidity adjustment instruction.

[0053] 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 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.

[0054] For example, 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 is set to 45% RH. The target humidity may be the most comfortable humidity value for the previous user. If other users feel that the environment is still relatively humid at this time, the target humidity can be controlled to be lowered, such as setting the target humidity to 42% RH. For another example, 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 is set to 65% RH. If the user feels that the environment is still relatively dry at this time, the target humidity can be controlled to be higher, such as setting the target humidity to 68% RH. Therefore, by adjusting the target humidity, the needs of different groups of people can be met, which is more humane.

[0055] According to an embodiment of the present invention, the fan speed and compressor frequency of the dehumidification equipment are controlled according to the humidity difference, including: determining the humidity configuration interval where the humidity difference is located; determining the corresponding fan speed and compressor frequency according to the humidity configuration interval where the humidity difference is located; and controlling the fan and compressor in the dehumidification equipment to operate according to the corresponding fan speed and compressor frequency. The fan speed and compressor frequency are positively correlated with the humidity difference.

[0056] Specifically, after calculating the humidity difference between the indoor environment humidity and the target humidity, the humidity configuration interval in which the humidity difference is located 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 according to different humidity differences. For example, when the humidity difference is 20%, the humidity difference can be identified as being in a high humidity configuration interval, when the humidity difference is 10%, the humidity difference can be identified as being in a medium humidity configuration interval, and when the humidity difference is 5%, the humidity difference can be identified as being in a low humidity configuration interval.

[0057] After determining the humidity configuration interval, the corresponding fan speed and compressor frequency can be determined according to the humidity configuration interval where the difference value is located, so that the fan and compressor in the dehumidification equipment can be controlled to operate according to the corresponding fan speed and compressor frequency. For example, a table lookup method can be used, such as in a table of humidity configuration interval-fan speed-compressor frequency, to store multiple humidity configuration intervals and fan speed and compressor frequency values, different humidity configuration intervals correspond to different fan speeds and compressor frequencies, and the humidity configuration interval and the fan speed are in a one-to-one correspondence, and the humidity configuration interval and the compressor frequency are in a one-to-one correspondence. When a humidity configuration interval is determined, the corresponding fan speed and compressor frequency can be determined.

[0058] 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, bringing a better experience to users. 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 energy saving.

[0059] According to one embodiment of the present invention, 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 according to 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, the third fan speed and the third compressor frequency are determined, and the target operating speed of the fan is determined according to the second fan speed, the third fan speed, the humidity difference, the second preset humidity threshold and the third preset humidity threshold, and the target operating frequency of the compressor is determined according to the second compressor frequency, the third compressor frequency, the humidity difference, the second preset humidity threshold and the third preset humidity threshold, wherein 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 according to actual conditions.

[0060] Specifically, when dividing the humidity configuration interval, for example, when the humidity difference is greater than or equal to the first preset humidity threshold, it can be determined that the humidity difference is in the high humidity configuration interval, when the humidity difference is less than the first preset humidity threshold and greater than or equal to the second preset humidity threshold, the humidity difference is in the medium humidity configuration interval, and when the humidity difference is less than the second preset humidity threshold, the humidity difference is in the low humidity configuration interval. When determining the corresponding fan speed and compressor frequency according to 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 means that the difference between the indoor humidity and the target humidity is too large, and 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 first fan speed can be determined as Spd1 and the first compressor frequency can be determined as F1 according to the humidity difference through a table lookup method, 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, thereby quickly reducing the difference between the indoor humidity and the target humidity, and can quickly reduce the indoor humidity and improve the user's comfort.

[0061] The temperature difference is compared with the first preset humidity threshold and the second humidity threshold. When the humidity difference is less than the first preset humidity threshold, and the humidity difference is greater than or equal to the second preset humidity threshold, it means that the difference between the indoor humidity and the target humidity is large, and the second fan speed and the second compressor frequency can be determined. For example, according to the table lookup method, the second fan speed can be determined as Spd2 according to the humidity difference, and the second compressor frequency can be determined as F2. After determining the second fan speed and the second compressor frequency, the target operating speed of the fan can be determined 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 the target operating frequency of the compressor can be determined according to 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 operating speed of the fan can be determined according to the formula target operating 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.

[0062] The humidity difference is compared with the second preset humidity threshold and the third preset humidity threshold. When the humidity difference is less than the second preset humidity threshold and the humidity difference is greater than or equal to the third preset humidity threshold, the third fan speed and the third compressor frequency can be determined. For example, the third fan speed can be determined as Spd3 according to the humidity difference, and the third compressor frequency can be determined as F3 by table lookup. After determining the third fan speed and the third compressor frequency, the target operating speed of the fan can be determined according to the second fan speed, the third fan speed, the humidity difference, the second preset humidity threshold and the third preset humidity threshold, and the target operating frequency of the compressor can be determined according to the second compressor frequency, the third compressor frequency, the humidity difference, the second preset humidity threshold and the third preset humidity threshold. For example, the target operating speed of the fan can be determined according to the formula target operating 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.

[0063] It should be noted that the magnitudes of the first compressor frequency, the second compressor frequency, and the third compressor frequency decrease in sequence, and the magnitudes of the first fan speed, the second fan speed, and the third fan speed decrease in sequence. And when changing the compressor frequency and the fan speed, the above formula is used to determine the compressor frequency and the fan speed linearly, rather than directly adjusting from a higher value to a lower value, so as to achieve a better comfort and improve the user experience.

[0064] According to an embodiment of the present invention, 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.

[0065] Specifically, when comparing the humidity difference with the third preset humidity threshold, if the humidity difference is less than the third preset humidity threshold, the fan can be controlled to stop, and the compressor can be controlled to stop, so as to achieve the purpose of saving power. For example, 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. If the third preset humidity threshold currently set is 0%RH, then the humidity difference -5%RH is less than the third preset humidity threshold 0%RH. At this time, it means that the current indoor environmental humidity has reached the target humidity and is lower than the target humidity.
