[0002] Currently, commercial areas such as shopping malls or warehouses often have different requirements for indoor air humidity.

[0008] In some embodiments, the step of correcting the current outdoor relative humidity to obtain the corrected current outdoor relative humidity includes: correcting the current outdoor relative humidity according to the formula W = W1 - (T1 - T) / 100, where W is the corrected current outdoor relative humidity, W1 is the current outdoor relative humidity, T1 is the current outdoor temperature, and T is the preset outdoor temperature.

[0009] In some embodiments, obtaining the operating mode of the humidity control device includes: obtaining indoor humidity; if the indoor humidity is greater than a first preset indoor humidity, determining the operating mode of the humidity control device to be the external circulation dehumidification mode; if the indoor humidity is less than a second preset indoor humidity, determining the operating mode of the humidity control device to be the external circulation humidification mode; wherein, the first preset indoor humidity is greater than the second preset indoor humidity.

[0010] In some embodiments, the humidity control device is provided with a fresh air vent that can connect indoor and outdoor environments, and the control method further includes: if the indoor humidity is greater than or equal to the second preset indoor humidity and less than or equal to the first preset indoor humidity, and the indoor air quality is lower than a preset indoor standard, the fresh air vent is opened.

[0011] In some embodiments, the control method further includes: when the humidification device is operating in the external circulation humidification mode, acquiring outdoor air quality; if the outdoor air quality is greater than or equal to a first preset outdoor standard, acquiring a new current outdoor relative humidity, and controlling the start and stop of the external circulation humidification mode according to the magnitude of the new current outdoor relative humidity and the first preset relative humidity; if the outdoor air quality is less than the first preset outdoor standard, turning off the external circulation humidification mode.

[0012] In some embodiments, the control method further includes: when the humidification device is operating in the external circulation dehumidification mode, acquiring the outdoor air quality; if the outdoor air quality is greater than or equal to a second preset outdoor standard, acquiring a new current outdoor relative humidity, and controlling the start and stop of the external circulation dehumidification mode according to the magnitude of the new current outdoor relative humidity and the second preset relative humidity; if the outdoor air quality is less than the second preset outdoor standard, turning off the external circulation dehumidification mode.

[0013] The second aspect of the present invention provides a control device for a humidity control device, comprising: an acquisition module configured to acquire the operating mode of the humidity control device and the current outdoor relative humidity; a humidification activation module configured to activate the external circulation humidification mode if the current outdoor relative humidity is greater than or equal to a first preset relative humidity when the operating mode is an external circulation humidification mode; a humidification deactivation module configured to deactivate the external circulation humidification mode if the current outdoor relative humidity is less than the first preset relative humidity; a dehumidification deactivation module configured to deactivate the external circulation dehumidification mode if the current outdoor relative humidity is greater than or equal to a second preset relative humidity when the operating mode is an external circulation dehumidification mode; and a dehumidification activation module configured to activate the external circulation dehumidification mode if the current outdoor relative humidity is less than the second preset relative humidity.

[0016] The control method and control device for a humidity control device provided in this disclosure, as well as the humidity control device itself, can achieve the following technical effects:

[0017] In external circulation humidification mode, outdoor air absorbs moisture from the desiccant and is discharged into the room. The relative humidity of the outdoor environment reflects the moisture content of the outdoor air, thus affecting the moisture content of the outdoor air entering the room after absorbing moisture from the desiccant, and consequently affecting the humidification effect. Therefore, controlling the start and stop of the external circulation humidification mode based on the outdoor relative humidity can achieve a good humidification effect indoors. In external circulation dehumidification mode, outdoor air absorbs moisture through the desiccant and is discharged into the room. The higher the outdoor humidity, the higher the humidity of the air entering the room, given a fixed total amount of moisture absorbed by the desiccant. Therefore, the outdoor relative humidity affects the dehumidification effect indoors. Thus, controlling the start and stop of the external circulation dehumidification mode based on the outdoor relative humidity can achieve a good dehumidification effect indoors.

[0033] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure.

It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. Unless otherwise stated, the term "a plurality of" means two or more.

[0035] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0036] Combination Figure 7-13As shown, in some embodiments, a humidity control device includes: a housing 100, a humidity control turntable 200, and a first partition 300. The housing 100 defines a cavity 110, with one end of the cavity 110 having an opening; the humidity control turntable 200 is rotatably disposed within the cavity 110, and a flow cavity is defined between the upper end face of the humidity control turntable 200 and the inner wall of the cavity 110, allowing airflow to pass vertically through the humidity control turntable 200; the lower end face of the humidity control turntable 200 is located at the opening; the first partition 300 is rotatably disposed within the flow cavity, dividing the flow cavity into a first chamber 112 and a second chamber 113.

[0037] Using the humidity control device provided in this embodiment, when room temperature airflow flows through the humidity control disc 200, the moisture in the airflow is absorbed. Conversely, when heated airflow flows through the moisture-absorbing humidity control disc 200, the moisture inside the disc is released into the airflow. Utilizing this characteristic of the humidity control disc 200, it is driven to rotate continuously below the first chamber 112 and the second chamber 113. One of the airflows, either air or heated airflow, passes through the humidity control disc 200 located below the first chamber 112 and enters the first chamber 112, then flows out again through the humidity control disc 200 located below the first chamber 112. The other airflow passes through the humidity control disc 200 located below the second chamber 113 and enters the second chamber 113, then flows out again through the humidity control disc 200 located below the second chamber 113. The humidification turntable 200 allows for better absorption of moisture from the airflow or better release of absorbed moisture into the heated airflow, thus enabling better and continuous humidification or dehumidification of the room. It can also drive the rotation of the first partition 300 to switch the airflow channel according to the outdoor air quality, allowing for the exchange of indoor and outdoor airflow during humidification or dehumidification. This allows for the exchange of indoor and outdoor airflow when there is a need for indoor ventilation, and prevents the exchange of indoor and outdoor airflow when there is no need for ventilation due to poor outdoor air quality. This selectively utilizes outdoor airflow, reduces dependence on the outdoor environment, improves the stability of humidity regulation, and maintains indoor air quality.

[0038] Optionally, a heating device 310 is provided in the first chamber 112 and / or the second chamber 113. This allows the airflow passing through the first chamber 112 and / or the second chamber 113 to be heated, enabling the airflow exiting the first chamber 112 and / or the second chamber 113 to carry away moisture from the humidity control disc 200 located below the first chamber 112 and / or the second chamber 113, thus achieving humidification or dehumidification and providing better continuous humidification or dehumidification of the room.

[0039] The humidity control disc contains moisture-absorbing material. When airflow passes through the humidity control disc, the moisture in the airflow is absorbed by the moisture-absorbing material, or the moisture absorbed by the moisture-absorbing material is released into the airflow, thereby better humidifying or dehumidifying the room.

[0040] Optionally, both the first chamber 112 and the second chamber 113 are equipped with heating devices 310. This allows the indoor environment to be dehumidified or humidified regardless of whether it is in internal or external circulation mode, by controlling the opening and closing of the heating devices 310 in the first chamber 112 and the second chamber 113. Furthermore, the two heating devices 310 are positioned on the same horizontal line and intersected with the first partition 300, ensuring that the airflow passing through the first chamber 112 or the second chamber 113 is better heated, thus improving the humidification or dehumidification of the indoor environment. For example, when the indoor environment is in recirculation mode, the first chamber 112 is connected to the indoor environment, and the second chamber 113 is connected to the outdoor environment. By controlling the heating device 310 in the first chamber 112 to be turned off and the heating device 310 in the second chamber 113 to be turned on, the moisture-absorbing material in the humidity-regulating disc 200 located below the first chamber 112 absorbs moisture from the airflow flowing through the first chamber 112, heating the airflow flowing through the second chamber 113. The heated airflow then carries away the moisture from the moisture-absorbing material in the humidity-regulating disc 200 located below the second chamber 113, thus dehumidifying the indoor environment. Alternatively, the heating device 310 in the first chamber 112 can be turned on and the heating device 310 in the second chamber 113 can be turned off. The humidity-regulating disc 200 located below the second chamber 113 absorbs moisture from the airflow flowing through the second chamber 113, heating the airflow flowing through the first chamber 112. The heated airflow then carries away the water from the humidity-regulating disc 200 located below the first chamber 112. The first chamber 112 is connected to the outdoor environment, and the second chamber 113 is also connected to the outdoor environment. By controlling the heating device 310 in the first chamber 112 to turn off and the heating device 310 in the second chamber 113 to turn on, the moisture in the airflow from indoors to outdoors is absorbed by the humidity regulating disc 200 when it flows through the first chamber 112, and the airflow from outdoors to indoors is heated when it flows through the second chamber 113. The heated airflow carries away the moisture in the humidity regulating disc 200 and discharges it into the room, thus humidifying the indoor environment. Alternatively, the heating device 310 in the first chamber 112 can be turned on and the heating device 310 in the second chamber 113 can be turned off. The moisture in the airflow from outdoors to indoors is absorbed by the humidity regulating disc 200 when it passes through the second chamber 113, and the airflow from indoors to outdoors is heated when it passes through the first chamber 112. The heated airflow carries away the moisture in the humidity regulating disc 200 and discharges it into the room, thus dehumidifying the indoor environment.

[0041] For ease of description, the heating device located in the first chamber is named the first heating device, and the heating device located in the second chamber is named the second heating device. Either the first or second heating device can be turned on. The humidification device also includes fans, including a first fan and a second fan. The first fan corresponds to the first heating device, and the air driven by the first fan can flow through the first heating device. The second fan corresponds to the second heating device, and the air driven by the second fan can flow through the second heating device. When the first heating device is on and the second heating device is off, the first fan is a regenerator fan, and the second fan... When the first heating device is off and the second heating device is on, the first fan is a desiccant fan and the second fan is a regeneration fan. In this case, the air passing through the first heating device flows through the desiccant material, absorbs the moisture in the desiccant material, and regenerates the desiccant material. The air passing through the second heating device also absorbs the moisture in the desiccant material, thus humidifying the air.

[0042] Optionally, the humidity control device includes a drive device connected to the humidity control turntable, which drives the humidity control turntable to rotate, so that the humidity control turntable 200 continuously rotates below the first chamber 112 and the second chamber 113, continuously absorbing and releasing moisture during the rotation, thereby better humidifying or dehumidifying the room.

[0043] In some alternative embodiments, the humidity control device further includes a housing 700. The housing 700 defines an installation cavity, the cover 100 is installed in the installation cavity, and the cover is provided with a partition plate 750. The installation cavity is divided into a first airflow cavity 710, a second airflow cavity 720, a third airflow cavity 730 and a fourth airflow cavity 740 by the cooperation of the cover 100 and the partition plate 750. In this way, during the humidification or dehumidification of the indoor environment, the rotation of the first partition 300 can be driven to switch the airflow channels according to the outdoor air quality and / or outdoor humidity, thereby switching the connection relationship between the first airflow chamber 710, the second airflow chamber 720, the third airflow chamber 730 and the fourth airflow chamber 740. This allows for the exchange of indoor and outdoor airflow during humidification or dehumidification, or the absence of such exchange. Furthermore, when there is a need for indoor ventilation, the indoor and outdoor airflows can be exchanged; when outdoor air quality is poor and there is no need for ventilation, the exchange can be prevented. This avoids polluted outdoor air entering the room, selectively utilizes outdoor airflow, reduces dependence on the outdoor environment, improves the stability of humidity regulation, and maintains indoor air quality.

[0044] Optionally, a first vent 751 is provided between the first airflow chamber 710 and the third airflow chamber 730, and a second vent 752 is provided between the second airflow chamber 720 and the fourth airflow chamber 740. In this way, during internal circulation connecting indoor and outdoor spaces, and when the outdoor environmental quality is high, the first airflow chamber 710 is connected to the second airflow chamber 720, and the third airflow chamber 730 is connected to the fourth airflow chamber 740. At this time, a small amount of outdoor air can enter the room through the first vent 751, and a small amount of indoor air can be discharged to the outside through the second vent 752, achieving a micro-fresh air outdoor circulation and improving indoor air quality.

[0045] Optionally, the first vent 751 is disposed on the partition plate 750 between the first airflow chamber 710 and the third airflow chamber 730, and the second vent 752 is disposed on the partition plate 750 between the second airflow chamber 720 and the fourth airflow chamber 740, and both the first vent 751 and the second vent 752 are provided with a switch structure. In this way, the first vent 751 and the second vent 752 can facilitate micro-fresh air exchange between indoor and outdoor environments, improving indoor air quality, and the opening and closing of the first vent 751 and the second vent 752 can be controlled by the switch structure.

[0046] Optionally, the cover 100 is positioned in the middle of the mounting cavity. This ensures that the first airflow cavity 710, the second airflow cavity 720, the third airflow cavity 730, and the fourth airflow cavity 740 separated by the cover 100 are of uniform size and have relatively uniform flow areas, allowing for smoother airflow.

[0047] Optionally, when the first partition 300 is in the first position, the first airflow chamber 710 is connected to the second airflow chamber 720, and the third airflow chamber 730 is connected to the fourth airflow chamber 740; when the first partition 300 is in the second position, the first airflow chamber 710 is connected to the third airflow chamber 730, and the second airflow chamber 720 is connected to the fourth airflow chamber 740. Thus, by switching the position of the first partition 300, the connectivity of the flow channels within the housing 700 can be switched, allowing for connections between outdoor and outdoor environments, indoor and indoor environments, or indoor and outdoor environments. This allows for continuous humidification or dehumidification of the indoor environment while simultaneously adjusting the airflow channels based on the quality of the outdoor environment, thus improving environmental adaptability.

[0048] Optionally, the housing 700 includes a first air inlet 701 and a first air outlet 702 connecting to the outside, and a second air inlet 703 and a second air outlet 704 connecting to the inside. The first air inlet 701 is connected to a first airflow chamber 710, the first air outlet 702 is connected to a second airflow chamber 720, the second air outlet 704 is connected to a third airflow chamber 730, and the second air inlet 703 is connected to a fourth airflow chamber 740. Thus, by switching the position of the first partition 300, the connectivity of the airflow channels within the housing 700 can be switched, thereby switching the connectivity between the inside and outside. This allows for continuous humidification or dehumidification of the indoor environment while simultaneously adjusting the airflow channels according to the quality of the outdoor environment, improving environmental adaptability. For example, when the first partition 300 is in the first position, outdoor airflow enters the first airflow chamber 710 through the first air inlet 701, then passes through the first air inlet 230 on the lower end face of the humidity control disc 200 and enters the first chamber 112. It then flows out through the first air outlet 240 and into the second airflow chamber 720, finally exiting through the first air outlet 702 to the outside, completing one outdoor airflow cycle. Indoor airflow enters the fourth airflow chamber 740 through the second air inlet 703, then enters the second chamber 113 through the second air inlet 250 on the lower end face of the humidity control disc 200. It then flows out through the second air outlet 260 and into the third airflow chamber 730, finally exiting through the second air outlet 704 to the room, completing one indoor airflow cycle. At this time, the outdoor and indoor airflows are connected. The system is connected to the indoor environment. When the first partition 300 is in the second position, outdoor airflow enters the first airflow chamber 710 through the first air inlet 701, then passes through the first air inlet 230 on the lower end face of the humidity control disc 200 and enters the first chamber 112. It then passes through the second air outlet 260 and is blown into the third airflow chamber 730. Finally, it is blown into the indoor environment through the second air outlet 704, completing one outdoor-to-indoor cycle. Indoor airflow enters the fourth airflow chamber 740 through the second air inlet 703, then passes through the second air inlet 250 on the lower end face of the humidity control disc 200 and enters the second chamber 113. It then flows out through the first air outlet 240 and into the second airflow chamber 720. Finally, it is discharged to the outside through the first air outlet 702, completing one indoor-to-outdoor cycle. At this time, the indoor environment is connected to the outdoor environment.

[0049] A fan 800 is provided at both the first air inlet 701 and the second air outlet 704. The fan at the first air inlet is used to drive air to flow between the first air inlet 701 and the part of the humidity control disc corresponding to the first air inlet. The fan at the second air outlet 704 is used to drive air to flow between the second air outlet 704 and the part of the humidity control disc corresponding to the second air outlet 704.

[0050] In some instances, a condenser 760 is provided in the first airflow chamber 710 and / or the fourth airflow chamber 740. An evaporator 770 is provided in the second airflow chamber 720 and / or the third airflow chamber 730.

[0051] In internal circulation dehumidification, the first airflow chamber 710 and the second airflow chamber 720 are connected to the outside, and the third airflow chamber 730 and the fourth airflow chamber 740 are connected to the inside. The condenser 760 in the first airflow chamber 710 heats the airflow flowing in from the outside, allowing the airflow to more efficiently remove the moisture absorbed inside as it passes through the humidity control disc 200. The evaporator 770 in the third airflow chamber 730 performs secondary dehumidification on the dehumidified airflow flowing out of the humidity control disc 200, further reducing the moisture content of the airflow flowing into the room. In internal circulation humidification, the first airflow chamber 710 and the second airflow chamber 720 are connected to the outside, and the third airflow chamber 730 and the fourth airflow chamber 740 are connected to the inside. The condenser 760 in the fourth airflow chamber 740 heats the airflow flowing in from the inside, allowing the airflow to more efficiently remove the moisture absorbed inside as it passes through the humidity control disc 200, further improving the humidification effect. In external circulation dehumidification... In the case of external circulation humidification, the first airflow chamber 710 and the third airflow chamber 730 are connected to the outside, and the second airflow chamber 720 and the fourth airflow chamber 740 are also connected to the outside. The evaporator 770 in the third airflow chamber 730 can perform secondary dehumidification on the dehumidified outdoor airflow flowing out of the humidification disc 200, further reducing the moisture content of the airflow flowing into the room. The condenser 760 in the fourth airflow chamber 740 can heat the airflow flowing out of the room, so that the airflow can more efficiently remove the moisture absorbed inside when it flows through the humidification disc 200, further improving the dehumidification effect. In the case of external circulation humidification, the first airflow chamber 710 and the third airflow chamber 730 are connected to the outside, and the second airflow chamber 720 and the fourth airflow chamber 740 are also connected to the outside. The condenser 760 in the first airflow chamber 710 can heat the airflow flowing in from the outside, so that the airflow can more efficiently remove the moisture absorbed inside when it flows through the humidification disc 200, further improving the humidification effect.

[0052] In humidification mode, the humidification device can operate in internal circulation or external circulation mode. Internal circulation humidification means that outdoor air flows through the moisture-absorbing material, absorbs moisture, and is then discharged to the outside, while indoor air absorbs moisture from the moisture-absorbing material and flows into the room. External circulation humidification mode means that indoor air flows through the moisture-absorbing material, absorbs moisture, and is then discharged to the outside, while outdoor air absorbs moisture from the moisture-absorbing material and is then discharged into the room.

[0053] In dehumidification mode, the dehumidification device can operate in internal circulation dehumidification or external circulation dehumidification. External circulation dehumidification mode means that outdoor air flows through the moisture-absorbing material and is discharged into the room after the moisture-absorbing material absorbs moisture, while indoor air absorbs moisture from the moisture-absorbing material and is discharged into the room. Internal circulation dehumidification mode means that indoor air flows through the moisture-absorbing material and is discharged into the room after the moisture-absorbing material absorbs moisture, while outdoor air absorbs moisture from the moisture-absorbing material and is discharged into the room.

[0054] Combination Figure 1 As shown, this disclosure provides a control method for a humidity control device, including steps S101-S103.

[0055] Step S101: The humidity control device acquires its operating mode and the current outdoor relative humidity.

[0056] The operating modes include external circulation humidification mode and external circulation dehumidification mode. In external circulation humidification mode, the indoor environment is humidified, and in external circulation dehumidification mode, the indoor environment is dehumidified.

[0057] There are many ways to obtain the relative humidity of the current outdoor environment. For example, you can set up a humidity sensor outdoors to obtain the relative humidity of the current outdoor environment, or you can obtain the relative humidity of the current outdoor environment through weather forecasts.

[0058] Step S102: When the operating mode is external circulation humidification mode, if the current outdoor relative humidity is greater than or equal to the first preset relative humidity, the humidification device turns on the external circulation humidification mode; if the current outdoor relative humidity is less than the first preset relative humidity, the humidification device turns off the external circulation humidification mode.

[0059] When the current outdoor relative humidity is greater than or equal to the first preset relative humidity, it indicates that the current outdoor relative humidity is high. Outdoor air can be used to humidify the indoor environment. Indoor air flows through the moisture-absorbing material, which absorbs moisture from the indoor air. The moisture-absorbing air then flows out to the outside, where outdoor air absorbs moisture from the material, further increasing the moisture content of the outdoor air and enabling the regeneration of the moisture-absorbing material. The moisture-absorbing outdoor air then flows back into the room to quickly increase the indoor relative humidity. When the current outdoor relative humidity is less than the first preset relative humidity, it indicates that the current outdoor relative humidity is low. Using outdoor air to humidify the room is not very effective. Therefore, the external circulation humidification mode is turned off. In this case, the humidification device can be controlled to operate in internal circulation humidification mode. In internal circulation humidification mode, outdoor air flows through the moisture-absorbing material, which absorbs moisture from the outdoor air. The moisture-absorbing air then flows out to the outside, where indoor air absorbs moisture from the material, further increasing the moisture content of the indoor air and enabling the regeneration of the moisture-absorbing material. The moisture-absorbing outdoor air then flows back into the room to quickly increase the indoor relative humidity.

[0060] Step S103: When the operating mode is external circulation dehumidification mode, if the current outdoor relative humidity is greater than or equal to the second preset relative humidity, the dehumidification device turns off the external circulation dehumidification mode; if the current outdoor relative humidity is less than the second preset relative humidity, the dehumidification device turns on the external circulation dehumidification mode.

[0061] When the current outdoor relative humidity is greater than or equal to the second preset relative humidity, it indicates that the current outdoor relative humidity is high. Outdoor air should not be allowed to flow into the room to avoid increasing the indoor relative humidity. Therefore, the external circulation dehumidification mode should be turned off. In this mode, the dehumidification device can be controlled to operate in internal circulation dehumidification mode. In internal circulation dehumidification mode, indoor air flows through the moisture-absorbing material. After the material absorbs moisture from the indoor air, the moisture-absorbing air flows into the room to reduce the indoor relative humidity. Outdoor air absorbs moisture from the moisture-absorbing material, regenerating it, and then flows out, preventing an increase in indoor relative humidity. When the current outdoor relative humidity is less than the second preset relative humidity, it indicates that the current outdoor relative humidity is low. Outdoor air can be dehumidified and then flow into the room to reduce the indoor relative humidity. Therefore, the external circulation dehumidification mode should be selected. In this mode, outdoor air flows through the moisture-absorbing material. After the material absorbs moisture from the outdoor air, the moisture-absorbing air flows into the room to reduce the indoor relative humidity. Indoor air absorbs moisture from the moisture-absorbing material, regenerating it, and then flows out.

[0062] Optionally, combined Figure 2 As shown, in one embodiment, the control method includes steps S201-S204.

[0063] Step S201: The humidity control device acquires its operating mode and the current outdoor relative humidity.

[0064] Step S202: The humidity control device corrects the current outdoor relative humidity to obtain the corrected current outdoor relative humidity.

[0065] Relative humidity refers to the percentage of water vapor pressure in the air to the saturated water vapor pressure at the same temperature. It reflects the ratio of water content to the tolerable saturated water content at a given temperature. The absolute humidity corresponding to the same relative humidity differs at different temperatures; therefore, temperature corrections are needed to eliminate or reduce the influence of temperature on relative humidity.

[0066] Step S203: When the operating mode is external circulation humidification mode, if the corrected current outdoor relative humidity is greater than or equal to the first preset relative humidity, the humidification device turns on the external circulation humidification mode; if the corrected current outdoor relative humidity is less than the first preset relative humidity, the humidification device turns off the external circulation humidification mode.

[0067] Step S204: When the operating mode is external circulation dehumidification mode, if the corrected current outdoor relative humidity is greater than or equal to the second preset relative humidity, the dehumidification device turns off the external circulation dehumidification mode; if the corrected current outdoor relative humidity is less than the second preset relative humidity, the dehumidification device turns on the external circulation dehumidification mode.

[0068] Optionally, step S202 involves correcting the current outdoor relative humidity to obtain the corrected current outdoor relative humidity, including:

[0069] The relative humidity of the current outdoor environment is corrected according to the formula W=W1-(T1-T) / 100, where W is the corrected relative humidity of the current outdoor environment, W1 is the current relative humidity of the current outdoor environment, T1 is the current outdoor temperature, and T is the preset outdoor temperature.

[0070] For example, when T is 25℃ and T1 is 35℃, W = W1 - (T1 - T)% = W1 - 10 / 100 = W1 - 10%.

[0071] This modified formula eliminates or reduces the influence of temperature on relative humidity, making it more accurate to control the start and stop of the external circulation humidification mode based on the relationship between the modified current outdoor relative humidity and the first preset relative humidity, thus improving the humidification effect. It also makes it more accurate to control the start and stop of the external circulation dehumidification mode based on the relationship between the modified current outdoor relative humidity and the second preset relative humidity, thus improving the dehumidification effect.

[0072] Optionally, obtaining the operating mode of the humidity control device in step S101 includes:

[0073] Obtain the indoor humidity; if the indoor humidity is greater than the first preset indoor humidity, determine the operating mode of the humidity control device to be the external circulation dehumidification mode; if the indoor humidity is less than the second preset indoor humidity, determine the operating mode of the humidity control device to be the external circulation humidification mode; wherein, the first preset indoor humidity is greater than the second preset indoor humidity.

[0074] There are many ways to obtain indoor humidity. For example, you can install a humidity sensor indoors to obtain indoor humidity, or you can obtain indoor humidity through weather forecasts.

[0075] If the indoor humidity is higher than the first preset indoor humidity, it indicates that the indoor humidity is high and the external circulation dehumidification mode is required. If the indoor humidity is lower than the second preset indoor humidity, it indicates that the indoor humidity is low and the external circulation humidification mode is required. If the indoor humidity is higher than or equal to the second preset indoor humidity and lower than or equal to the first preset indoor humidity, it indicates that the indoor humidity meets the range of comfortable indoor humidity (higher than or equal to the second preset indoor humidity and lower than or equal to the first preset indoor humidity), and humidification or dehumidification is not required. The humidity control device can be turned off.

[0076] In one specific embodiment, the control method includes:

[0077] To obtain indoor humidity, such as indoor relative humidity W2, outdoor relative humidity W1, preset outdoor temperature T, current outdoor temperature (current actual outdoor temperature) T1, the corrected current outdoor relative humidity W = W1 - (T1 - T) / 100.

[0078] When the indoor relative humidity W2 < 40%, turn off the external circulation humidifier if W < 40%; turn on the external circulation humidifier if W ≥ 40%.

[0079] When the indoor relative humidity W2 > 65% and W < 40%, turn on the external circulation dehumidifier; when W ≥ 40%, turn off the external circulation humidifier.

[0080] Optionally, the humidification device is equipped with a fresh air vent (first vent) that connects the indoor and outdoor areas, and the control method further includes:

[0081] If the indoor humidity is greater than or equal to the second preset indoor humidity and less than or equal to the first preset indoor humidity, and the indoor air quality is lower than the preset indoor standard, the fresh air vent will be turned on.

[0082] If the indoor humidity is greater than or equal to the second preset indoor humidity and less than or equal to the first preset indoor humidity, it means that the indoor humidity meets the range of comfortable indoor humidity. At this time, the indoor humidity meets the user's requirements, and the humidity adjustment operation (including external circulation humidification and external circulation dehumidification) can be stopped. If the indoor air quality is lower than the preset indoor standard, it means that the indoor air quality is poor. The fresh air vent can be opened to introduce outdoor air into the room to realize the fresh air mode and improve the indoor air quality.

[0083] In a specific embodiment, when the indoor humidity is 40% (second preset indoor humidity) ≤ indoor humidity W2 ≤ 65% (first preset indoor humidity), the indoor air quality is obtained, for example, the indoor CO2 concentration is used to represent the indoor air quality. When the indoor CO2 concentration is higher than the first set value (e.g., 800ppm), the corresponding indoor air quality is lower than the preset indoor standard, the fresh air vent is opened, and the external circulation fresh air mode is activated; when the indoor CO2 concentration is lower than the second set value (e.g., 400ppm), the fresh air vent is closed, and the external circulation fresh air mode is turned off.

[0084] Optionally, combined Figure 3 As shown, in some embodiments, the control method includes steps S301-S303.

[0085] Step S301: When the humidification device is operating in external circulation humidification mode, the humidification device obtains the outdoor air quality.

[0086] Outdoor air quality can be obtained through air quality detectors or weather forecasts.

[0087] Step S302: If the outdoor air quality is greater than or equal to the first preset outdoor standard, the humidification device obtains the new current outdoor relative humidity and controls the start and stop of the external circulation humidification mode according to the difference between the new current outdoor relative humidity and the first preset relative humidity. Specifically, if the new current outdoor relative humidity is greater than or equal to the first preset relative humidity, the external circulation humidification mode is turned on; if the new current outdoor relative humidity is less than the first preset relative humidity, the external circulation humidification mode is turned off.

[0088] If the outdoor air quality is greater than or equal to the first preset outdoor standard, it indicates that the outdoor air quality is good. The outdoor air quality does not affect the start and stop control of the external circulation humidification mode. Therefore, the start and stop of the external circulation humidification mode is still controlled according to the relationship between the current outdoor relative humidity (the new current outdoor relative humidity) and the first preset relative humidity.

[0089] Step S303: If the outdoor air quality is lower than the first preset outdoor standard, the humidification device shuts off the external circulation humidification mode.

[0090] If the outdoor air quality is lower than the first preset outdoor standard, it indicates that the outdoor air quality is poor. For example, when it is smoggy weather outside, outdoor air should be reduced or avoided from entering the room to affect the indoor air quality. In this case, the external circulation humidification mode is no longer controlled based on the relationship between the current outdoor relative humidity and the first preset relative humidity. Instead, the external circulation humidification mode is turned off, and the internal circulation humidification mode can be selected.

[0091] Optionally, the humidifier can be turned off when there is a sandstorm outdoors.

[0092] Optionally, combined Figure 4 As shown, in some embodiments, the control method includes steps S401-S403.

[0093] Step S401: When the humidification device is operating in external circulation dehumidification mode, the humidification device obtains the outdoor air quality.

[0094] Step S402: If the outdoor air quality is greater than or equal to the second preset outdoor standard, the humidity control device obtains the new current outdoor relative humidity and controls the start and stop of the external circulation dehumidification mode according to the difference between the new current outdoor relative humidity and the second preset relative humidity. Specifically, if the new current outdoor relative humidity is greater than or equal to the second preset relative humidity, the external circulation dehumidification mode is turned off; if the new current outdoor relative humidity is less than the second preset relative humidity, the external circulation dehumidification mode is turned on.

[0095] If the outdoor air quality is greater than or equal to the second preset outdoor standard, it indicates that the outdoor air quality is good. The outdoor air quality does not affect the start and stop control of the external circulation dehumidification mode. Therefore, the start and stop of the external circulation dehumidification mode is still controlled according to the relationship between the current outdoor relative humidity (the new current outdoor relative humidity) and the second preset relative humidity.

[0096] Step S403: If the outdoor air quality is lower than the second preset outdoor standard, the humidification device shuts off the external circulation dehumidification mode.

[0097] If the outdoor air quality is lower than the second preset outdoor standard, it indicates that the outdoor air quality is poor. Outdoor air should be reduced or avoided from entering the room to affect the indoor air quality. In this case, the external circulation dehumidification mode will no longer be controlled based on the relationship between the current outdoor relative humidity and the second preset relative humidity. Instead, the external circulation dehumidification mode will be turned off, and the internal circulation dehumidification mode can be selected.
