In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0019] Unless otherwise specified, the term "plurality" means two or more than two.

[0020] In the embodiments of the present disclosure, the character " / " indicates that the objects before and after are in an "or" relationship. For example, A / B means: A or B.

[0021] The term "and / or" is an associative relationship describing an object, indicating that there can be three relationships. For example, A and / or B means: A or B, or, A and B these three relationships.

[0022] Combined with Figure 1 As shown, the embodiments of the present disclosure provide a method for controlling a humidifier, including:

[0023] Step S01, controlling the power of the heating device according to the difference ΔT between the outdoor ambient temperature and the temperature at the outlet of the humidifying channel;

[0024] Step S02, controlling the power of the first fan and the second fan according to the difference Δd between the outdoor ambient humidity and the humidity at the outlet of the humidifying channel.

[0025] By using the method for controlling a humidifier provided by the embodiments of the present disclosure, during the working process of the humidifier, it is possible to judge the outdoor ambient temperature and the temperature at the outlet of the humidifying channel, and control the operation of the heating device according to the temperature difference, prevent the condensation phenomenon caused by too large a temperature difference, and control a reasonable heating power to reduce energy consumption. It is also possible to judge the outdoor ambient humidity and the humidity at the outlet of the humidifying channel, and control the power of the fans in the humidifying channel and the moisture absorption channel, so that the humidity is maintained within a stable range, prevent the condensation phenomenon caused by too high humidity, and keep the power of the fans within a reasonable range to reduce energy consumption.

[0026] Optionally, controlling the power of the heating device according to the difference ΔT between the outdoor ambient temperature and the temperature at the outlet of the humidification channel includes: increasing the power of the electric heating device when ΔT is less than the first temperature difference threshold; or maintaining the power of the electric heating device unchanged when ΔT is greater than or equal to the first temperature difference threshold and less than or equal to the second temperature difference threshold; or decreasing the power of the electric heating device when ΔT is greater than the second temperature difference threshold. In this way, when ΔT is less than the first temperature difference threshold, it indicates that the heating amount of the heating device is low and cannot completely regenerate the moisture contained in the moisture absorption plate. At this time, increasing the power of the heating device can better heat the moisture absorption plate and increase the moisture release amount; when ΔT is greater than or equal to the first temperature difference threshold and less than or equal to the second temperature difference threshold, it can be explained within this range that the moisture on the moisture absorption plate can be normally regenerated. At this time, keeping the power of the heating device unchanged is sufficient. When ΔT is greater than the second temperature difference threshold, it indicates that the heat of the heating device can completely regenerate the moisture on the moisture absorption plate. At this time, decreasing the power of the electric heating device can reduce the energy loss, and reducing the temperature can prevent the high-temperature water vapor from condensing instantaneously due to pre-cooling at high temperatures, thereby affecting the humidification efficiency.

[0027] Optionally, the difference between ΔT and the first temperature difference threshold is proportional to the increased power of the electric heating device. In this way, the power adjustment of the electric heating device is more accurate and reliable, enabling the power of the electric heating device to be maintained within a better range.

[0028] Optionally, the difference between ΔT and the second temperature difference threshold is proportional to the decreased power of the electric heating device. In this way, the power adjustment of the electric heating device is more accurate and reliable, enabling the power of the electric heating device to be maintained within a better range.

[0029] Optionally, the first temperature difference threshold is greater than or equal to 10 degrees and less than or equal to 15 degrees, and the second temperature difference threshold is greater than or equal to 20 degrees and less than or equal to 25 degrees. In this way, when the first temperature difference threshold is within the range of 10 - 15 degrees, when the difference between the outdoor ambient temperature and the temperature at the outlet of the humidification channel is less than this temperature range, the heat of the heating device cannot completely regenerate the moisture on the moisture absorption plate. Based on this, it is more accurate to control the heating device to increase the power. When the second temperature difference threshold is within the range of 20 - 25 degrees, when the difference between the outdoor ambient temperature and the temperature at the outlet of the humidification channel is greater than this temperature range, the heat of the heating device can completely release the moisture on the moisture absorption plate. Based on this, it is more accurate to control the heating device to decrease the power.

[0030] Optionally, controlling the power of the first fan and the second fan according to the difference Δd between the outdoor environmental humidity and the humidity at the outlet of the humidification channel includes: when Δd is less than the first humidity difference threshold, reducing the power of the first fan and / or increasing the power of the second fan; or when Δd is greater than or equal to the first humidity difference threshold and less than or equal to the second temperature difference threshold, keeping the power of the first fan and the second fan unchanged; or when Δd is greater than the second humidity difference threshold, increasing the power of the first fan and / or reducing the power of the second fan. In this way, when the difference between the outdoor environmental humidity and the humidity at the outlet of the humidification channel is small, it indicates that the moisture content of the moisture absorption plate is low. By reducing the power of the first fan, unnecessary energy waste can be reduced. By increasing the power of the second fan, the air flow rate in the moisture absorption channel can be increased, the moisture absorption amount of the moisture absorption plate can be increased, and thus the humidification efficiency can be improved; when the difference between the outdoor environmental humidity and the humidity at the outlet of the humidification channel is between the first humidity difference threshold and the second humidity difference threshold, within this range, the moisture absorption amount and the moisture regeneration amount of the moisture absorption plate are relatively moderate. At this time, keeping the power of the first fan and the second fan can better perform humidification and maintain a high humidification efficiency; when the difference between the outdoor environmental humidity and the humidity at the outlet of the humidification channel is large, it indicates that the moisture released by the moisture absorption plate is large, resulting in excessive humidification amount and excessive humidity accumulation at the outlet of the humidification channel. When the humidity reaches a high level, condensation is likely to occur. At this time, increasing the power of the first fan to increase the ventilation volume of the humidification channel, and diluting the humidity at the outlet of the air outlet channel with a large air volume can effectively prevent the generation of condensation. And by reducing the power of the second fan, the air flow rate in the moisture absorption channel can be reduced, and thus the moisture absorption amount of the moisture absorption plate can be reduced, the humidification amount can be reduced, and energy waste can be avoided.

[0031] Optionally, the first humidity difference threshold is greater than or equal to 3 g / kg and less than or equal to 5 g / kg, and the second humidity difference threshold is greater than or equal to 7 g / kg and less than or equal to 9 g / kg. In this way, when the first humidity difference threshold is taken between 3 - 5 g / kg, when the difference between the outdoor environmental humidity and the humidity at the outlet of the humidification channel is less than this temperature difference region, it can better reflect that the moisture content of the moisture absorption plate is low. When the second humidity difference threshold is taken between 7 - 9 g / kg, when the difference between the outdoor environmental humidity and the humidity at the outlet of the humidification channel is greater than this temperature difference region, it can better illustrate that the moisture of the moisture absorption plate is not completely released, and more accurately control the reduction of the moisture absorption amount of the moisture absorption plate.

[0032] Optionally, when the Δd is less than the first humidity difference threshold, gradually increase the power of the second fan to the maximum power and decrease the power of the first fan. In this way, when the difference between the outdoor ambient humidity and the humidity at the outlet of the humidification channel is less than the first humidity difference threshold, it indicates that the moisture content of the moisture absorption plate is relatively low. At this time, increase the power of the second fan to the maximum to increase the air flow rate in the moisture absorption channel, thereby increasing the water absorption capacity of the moisture absorption plate. If insufficient moisture can still be absorbed even after the power of the second fan is increased to the maximum, it indicates that the moisture content in the air is too low. At this time, decrease the power of the first fan to avoid unnecessary energy waste.

[0033] Optionally, when the Δd is less than the first humidity difference threshold, first gradually increase the power of the second fan. After the power of the second fan increases to the maximum power, then decrease the power of the first fan. In this way, increasing the power of the second fan first can increase the air flow rate in the moisture absorption channel and absorb more moisture. If the demand still cannot be met after the power of the second fan increases to the maximum, it indicates that the moisture content in the outdoor air is too low. At this time, decreasing the power of the first fan can improve the humidification efficiency when the moisture content in the outdoor air is insufficient.

[0034] Optionally, when the Δd is greater than the second humidity difference threshold, if the indoor relative humidity is greater than or equal to a preset value, gradually decrease the power of the second fan to the minimum and increase the power of the first fan; if the indoor relative humidity is less than a preset value, gradually increase the power of the first fan to the maximum and decrease the power of the second fan. In this way, when the difference between the outdoor ambient humidity and the humidity at the outlet of the humidification channel is large, if the indoor relative humidity is greater than or equal to a preset value, it indicates that the indoor environment no longer has a humidification requirement. At this time, gradually decrease the power of the second fan to the minimum to reduce the air flow rate in the moisture absorption channel, thereby reducing the moisture absorption capacity of the moisture absorption plate, further reducing the amount of moisture regeneration in the humidification channel, reducing the humidification amount, and then reducing the humidity at the outlet of the humidification channel to prevent condensation; when the difference between the outdoor ambient humidity and the humidity at the outlet of the humidification channel is large, if the indoor relative humidity is less than a preset value, it indicates that the indoor environment still has a humidification requirement. At this time, gradually increase the power of the first fan to the maximum to increase the air flow rate in the humidification channel, so that the moisture on the moisture absorption plate can be completely released, and dilute the humidity at the outlet of the humidification channel to reduce the local humidity and prevent local high humidity from causing condensation. If the difference between the outdoor ambient humidity and the humidity at the outlet of the humidification channel is still greater than the second humidity difference threshold after the power of the first fan increases to the maximum, then decrease the power of the second fan, thereby reducing the air flow in the moisture absorption channel, reducing the moisture absorption, reducing the humidification efficiency, and further preventing the humidity at the outlet of the humidification channel from being too high, better preventing condensation, and avoiding unnecessary energy waste.

[0035] Optionally, when the Δd is greater than the second humidity difference threshold, if the indoor relative humidity is greater than or equal to a preset value, first gradually reduce the power of the second fan to the lowest level. After the power of the second fan reaches the lowest level, then increase the power of the first fan; if the indoor relative humidity is less than a preset value, first gradually increase the power of the first fan to the highest level. After the power of the first fan reaches the highest level, then reduce the power of the second fan. In this way, when the indoor relative humidity is greater than or equal to a preset value, it indicates that the indoor environment does not need to continue humidifying. At this time, first reduce the power of the second fan to reduce the air flow rate in the moisture absorption channel, thereby reducing the moisture absorption amount of the moisture absorption plate, reducing the humidification amount, and reducing unnecessary energy waste. If the Δd still does not drop to the appropriate range, then increase the power of the first fan to dilute the humidity at the outlet of the humidification channel by accelerating the air flow; when the indoor relative humidity is less than a preset value, it indicates that the indoor environment still needs humidifying. At this time, first increase the power of the first fan to dilute the humidity at the outlet of the humidification channel, and at the same time can maintain efficient humidification. After the power of the first fan increases to the highest level, if the Δd still does not drop to the appropriate range, then reduce the power of the second fan to reduce the air flow rate in the moisture absorption channel, thereby reducing the moisture absorption amount of the moisture absorption plate, and appropriately reducing the humidification amount in the humidification channel to prevent the problem of condensation caused by excessive local humidity.

[0036] Optionally, the preset value is greater than or equal to 50% and less than or equal to 80%. In this way, when the relative humidity of the indoor environment is higher than 50%-80%, the humidity is relatively high, which will reduce the user experience. Therefore, when the indoor relative humidity is greater than or equal to 50%-80%, it is determined that there is no need to continue humidifying the indoor environment, and the judgment result is relatively accurate, and the humidification process can be controlled more stably and efficiently.

[0037] Optionally, the preset value is 60%. In this way, when the relative humidity of the indoor environment is higher than 60%, the humidity is relatively high. At this time, it is determined that there is no need to continue humidifying the indoor environment, and the judgment result is relatively accurate, and the humidification process can be controlled more stably and efficiently.

[0038] Optionally, before controlling the power of the heating device according to the difference ΔT between the outdoor environmental temperature and the temperature at the outlet of the humidification channel, it further includes: judging the startup duration of the humidifier. When the startup duration exceeds a preset duration, control the power of the heating device according to the difference ΔT between the outdoor environmental temperature and the temperature at the outlet of the humidification channel. In this way, the control process is entered after the humidifier has been started for a period of time, which prevents errors in control caused by the instability of the humidifier when it first runs, and improves the stability of the humidifier operation.

[0039] Optionally, the preset duration is greater than or equal to 10 minutes and less than or equal to 20 minutes. In this way, the humidifier tends to be stable after starting for 10 - 20 minutes. At this time, the detected outdoor ambient temperature and the temperature at the outlet of the humidification channel are relatively accurate, improving the accuracy of control.

[0040] Optionally, the preset duration is 15 minutes. In this way, the humidifier tends to be stable after starting for 15 minutes. At this time, the detected outdoor ambient temperature and the temperature at the outlet of the humidification channel are relatively accurate, improving the accuracy of control.

[0041] Optionally, the method for controlling the humidifier further includes: controlling the heating of the side wall of the humidification channel according to the difference ΔT between the outdoor ambient temperature and the temperature at the outlet of the humidification channel, and the difference Δd between the outdoor ambient humidity and the humidity at the outlet of the humidification channel. In this way, by heating the side wall of the humidification channel, it is possible to prevent condensation from occurring when the hot and humid air encounters the relatively cold side wall of the humidification channel.

[0042] Optionally, when ΔT is greater than the second temperature difference threshold, and / or Δd is greater than the second humidity difference threshold, control the heating of the side wall of the humidification channel. In this case, when ΔT is greater than the second temperature difference threshold, it indicates that the outdoor temperature is relatively low and water vapor is likely to condense upon encountering cold. At this time, heating the side wall of the humidification channel can prevent the generation of condensation. When Δd is greater than the second humidity difference threshold, it indicates that the humidification amount is relatively high and the humidity is relatively high, making it easy to form saturated water vapor, and saturated water vapor is likely to liquefy to form a condensation phenomenon when encountering cold. At this time, heating the side wall of the humidification channel can prevent the generation of condensation.

[0043] Optionally, heating the side wall of the humidification channel includes: heating the humidification channel through a radiator disposed inside the side wall of the humidification channel, and the radiator is connected to a waste heat collection device, which is configured to collect waste heat generated during the operation of the motor, compressor, etc. In this way, heating the side wall of the humidification channel by collecting waste heat is more energy - saving and environmentally friendly.

[0044] Combined Figure 2 As shown, an embodiment of the present disclosure provides a device for controlling a humidifier, including a control module 200. The control module includes a first control unit 201 and a second control unit 202. The first control unit 201 is configured to control the power of the heating device according to the difference ΔT between the outdoor ambient temperature and the temperature at the outlet of the humidification channel; the second control unit 202 is configured to control the power of the first fan and the second fan according to the difference Δd between the outdoor ambient humidity and the humidity at the outlet of the humidification channel.

[0045] By using the method for controlling a humidifier provided in the embodiments of the present disclosure, during the operation of the humidifier, the outdoor ambient temperature and the temperature at the outlet of the humidification channel can be judged, and the operation of the heating device can be controlled according to the temperature difference, preventing the condensation phenomenon caused by too large a temperature difference, and controlling a reasonable heating power to reduce energy consumption. The outdoor ambient humidity and the humidity at the outlet of the humidification channel are judged, and the power of the fans in the humidification channel and the moisture absorption channel is controlled to keep the humidity within a stable range, preventing the condensation phenomenon caused by too high humidity, and keeping the power of the fans within a reasonable range to reduce energy consumption.

[0046] Optionally, the device for controlling a humidifier further includes: a detection module 300. The detection module includes a temperature detection unit 301 and a humidity detection unit 302. The temperature detection unit 301 is configured to detect the outdoor ambient temperature and the temperature at the outlet of the humidification channel; the humidity detection unit 302 is configured to detect the outdoor ambient humidity and the humidity at the outlet of the humidification channel. In this way, through the detection module 300, the temperature and humidity can be accurately detected, facilitating the provision of control parameters and enabling more stable control of the humidifier.

[0047] Optionally, the device for controlling a humidifier further includes: a calculation module 400. The calculation module is configured to calculate the difference ΔT between the outdoor ambient temperature and the temperature at the outlet of the humidification channel, and calculate the difference Δd between the outdoor ambient humidity and the humidity at the outlet of the humidification channel. In this way, by calculating the values of ΔT and Δd through the calculation module 400, it is convenient to control the humidification process of the humidifier according to ΔT and Δd.
