[0044] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0045] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0046] The following is for reference. Figures 1-7 The humidification module 100 of an embodiment of the present invention is described.

[0047] For example, in some embodiments, the humidification module 100 is suitable for installation in the fresh air system of the air handling unit 1000, and the humidification module 100 is located in the indoor air intake duct. When the humidity is suitable and the environment is humid, the humidification module 100 does not operate. When the indoor environment is dry, the outdoor fresh air passes through the humidification module 100, and the humidification module 100 humidifies the fresh air, thereby ensuring that the humidity of the indoor air intake is within a range suitable for human comfort. Of course, the present invention is not limited to this; the humidification module 100 can also be applied to other locations of the air handling unit 1000, such as in a heat exchange ventilation system. The present invention is not limited to this either; for example, the humidification module 100 can also be applied to other devices besides the air handling unit 1000, such as humidifiers, air purifiers, etc., which will not be elaborated here.

[0048] like Figure 2 and Figure 3 As shown, the humidification module 100 according to an embodiment of the present invention includes: a humidification component 10, a water supply component 20, a water recovery component 30, and a drainage component 40.

[0049] Specifically, the water supply component 20 is used to supply water to the humidification component 10, the recovery component 30 includes a water storage component 31 and a liquid level detection device 32. The water storage component 31 is used to store the dripping water from the humidification component 10, and the liquid level detection device 32 is used to detect the water level height of the water storage component 31, and includes a minimum water level detector 321 and a maximum water level detector 322. The drainage component 40 is used to drain the water storage component 31.

[0050] Therefore, the water supply component 20 supplies water to the humidification component 10 to ensure that the humidification component 10 has sufficient humidity, thereby ensuring the humidification effect of the humidification component 10 on the airflow. The water storage component 31 can store the dripping water of the humidification component 10, so that after the humidification component 10 has humidified the air, the remaining water on the humidification component 10 can directly or indirectly enter the water storage component 31 for storage (for example, the water storage component 31 can be a water receiving tray or a water storage box connected to the water receiving tray, etc.), thereby preventing too much water remaining on the humidification component 10 from flowing to other structures, which helps to protect other structures, and can collect the remaining water on the humidification component 10 to avoid waste.

[0051] The draining device is used to drain water from the water storage device 31, thereby reducing the water level in the water storage device 31 in a timely manner and preventing the water level in the water storage device 31 from being too high and causing overflow.

[0052] Furthermore, the liquid level detection device 32 includes a minimum water level detector 321 and a maximum water level detector 322, wherein both the water supply component 20 and the drainage component 40 are configured to perform corresponding actions based on the detection signals from the liquid level detection device 32. For example, the minimum water level detector 321 and the maximum water level detector 322 can be triggered when the water level in the water storage container 31 reaches the minimum and maximum water level heights, respectively, and both the water supply component 20 and the drainage component 40 are configured to perform corresponding actions based on the triggering status of the minimum water level detector 321 and the maximum water level detector 322. Alternatively, the minimum water level detector 321 and the maximum water level detector 322 can monitor the water level in the water storage container 31 in real time, and both the water supply component 20 and the drainage component 40 are configured to perform corresponding actions based on the real-time detection results of the minimum water level detector 321 and the maximum water level detector 322.

[0053] It should be noted that the minimum water level height in this invention refers to the set minimum water level height, such as the current water level height in the water storage container 31 when the minimum water level detector 321 is triggered, and not the actual minimum water level height that the water in the water storage container 31 can reach. Similarly, the maximum water level height refers to the set maximum water level height, such as the current water level height in the water storage container 31 when the maximum water level detector 322 is triggered, and not the actual maximum water level height that the water in the water storage container 31 can reach.

[0054] Therefore, the current water level in the water storage unit 31 can be determined by the minimum water level detector 321 and the maximum water level detector 322, and the water supply component 20 and the drainage component 40 can perform corresponding actions based on the current water level in the water storage unit 31. For example, the corresponding actions are to switch the water supply component 20 on and / or the drainage component 40 on, thereby avoiding the problem of excessively high water level in the water storage unit 31 and preventing the problem of reduced humidification efficiency of the humidification module 100 during long-term use. At the same time, it is convenient for users to judge the current status of the humidification module 100 based on the corresponding actions, so as to repair or replace the humidification module 100 in a timely manner, which helps to reduce the impact on the user's use.

[0055] For example, the water supply component 20 is connected to an external water circuit, such as a faucet, so that the water from the external water circuit can flow along the water supply component 20 to the humidification component 10. At this time, the airflow passing through the humidification component 10 is humidified so that the humidity of the incoming air is within a range suitable for human comfort.

[0056] Reference Figure 3As shown, the humidifying component 10 is detachably connected to the water storage component 31, which is located below the humidifying component 10 so that water on the humidifying component 10 can drip or flow into the water storage component 31 under the action of gravity, thereby storing the dripping water from the humidifying component 10. At least a portion of the humidifying component 10 extends into the water storage cavity of the water storage component 31. The liquid level detection device 32 is located in the water storage cavity and includes a minimum water level detector 321 and a maximum water level detector 322. The minimum water level detector 321 and the maximum water level detector 322 are triggered when the water in the water storage component 31 reaches the minimum water level height and the maximum water level height, respectively.

[0057] The lowest water level is lower than the highest water level; that is, in the direction perpendicular to the water level in the storage chamber, the height of the lowest water level detector 321 is lower than the height of the highest water level detector 322, and the detection height of the highest water level detector 322 is located above the measurement stroke of the lowest water level detector 321. This allows the lowest water level detector 321 and the highest water level detector 322 to detect different water levels within the storage container 31, thereby generating different detection signals.

[0058] This facilitates the water supply component 20 and the drainage component 40 to perform corresponding actions based on different detection signals. For example, the actions may include water supply and / or drainage. When the drainage action is performed, the drainage component 40 is turned on to avoid the problem of excessive water level in the water storage component 31. When the water supply action is performed, the water supply component 20 is turned on to ensure the humidification efficiency of the humidification module 100. At the same time, it allows the user to judge the current status of the humidification module 100 based on the corresponding actions, so as to repair or replace the humidification module 100 in a timely manner, thereby reducing the impact on the user's use.

[0059] According to the humidification module 100 of the present invention, by setting a liquid level detection device 32, and the water supply component 20 and the drainage component 40 being able to perform corresponding actions according to the detection signal of the liquid level detection device 32, on the one hand, the problem of reduced humidification efficiency of the humidification module 100 during long-term use can be avoided; on the other hand, it is convenient for users to judge the current status of the humidification module 100, so as to repair or replace the humidification module 100 in a timely manner, which helps to reduce the impact on the user's use and enhances the user's experience.

[0060] In some embodiments, the humidification module 100 has a first working mode. In the first working mode, when the water level in the water storage component 31 reaches or exceeds the minimum water level, the water supply component 20 is in a closed state and the drainage component 40 is in a closed state.

[0061] Therefore, when the water level in the water storage component 31 reaches or exceeds the minimum water level, the water supply component 20 is turned off to stop the water supply to the humidification component 10, thus preventing the water level in the water storage component 31 from continuing to rise. At the same time, the water in the water storage component 31 is drained by opening the drainage component 40, thereby reducing the water level in the water storage component 31 and preventing the water level in the water storage component 31 from overflowing due to excessive water level.

[0062] For example, the minimum water level detector 321 is triggered when the water level is at the minimum level. When the water level in the water storage unit 31 reaches or exceeds the minimum water level, the minimum water level detector 321 is activated, thereby controlling the water supply component 20 to close and the drainage component 40 to open, so as to stop the water inlet and start the drainage.

[0063] At this time, due to the drop in water level in the water storage component 31, the current water level in the water storage component 31 is lower than the minimum water level. When the current water level in the water storage component 31 is lower than the minimum water level, the water supply component 20 is turned on to continuously supply water to the humidification component 10, ensuring the humidification efficiency of the humidification component 10. Before the current water level in the water storage component 31 reaches the minimum water level, the drainage component 40 can be turned on to drain water while the water supply component 20 is receiving water, preventing the water level in the water storage component 31 from rising continuously. Alternatively, the drainage component 40 can be turned off to reduce the energy consumption of the drainage component 40 before the current water level in the water storage component 31 reaches the minimum water level. At the same time, since water has a certain degree of permeability, the water in the water storage component 31 is used to achieve a certain degree of humidification of the humidification component 10 through permeation.

[0064] Furthermore, the humidification module 100 also includes a humidity detection device (not shown in the figure).

[0065] The humidity detection device is used to detect the actual humidity of the environment. When the difference A between the actual humidity and the set humidity is less than or equal to the set difference △A, it enters the first working mode.

[0066] Therefore, by setting a humidity detection device, the humidification module 100 can enter the first working mode based on the relationship between the actual humidity of the environment and the set humidity.

[0067] For example, the humidity detection device can be installed on the side of the humidification module 100 facing the indoor side, which facilitates the humidity detection device to detect the humidity of the indoor environment and helps to avoid interference from the humidification module 100 to the humidity detection device.

[0068] In some embodiments, the humidification module 100 has a second working mode. In the second working mode, when the water level in the water storage component 31 reaches the minimum water level, or exceeds the minimum water level but does not reach the maximum water level, the water supply component 20 is in the open state and the drainage component 40 is in the open state.

[0069] Therefore, when the current water level of the water storage component 31 reaches the minimum water level, or when the current water level of the water storage component 31 is between the minimum and maximum water levels, the water supply component 20 is turned on and the drainage component 40 is turned on, so that while maintaining water intake, the water in the water storage component 31 is drained by turning on the drainage component 40.

[0070] For example, the highest water level detector 322 is triggered at the highest water level, so that the highest water level detector 322 can be triggered when the water level in the water storage unit 31 exceeds the lowest water level and reaches the highest water level.

[0071] It should be noted that when the humidification module 100 is working normally, the drainage volume of the drainage component 40 is greater than the difference between the water inlet volume of the water inlet component and the water consumption of the humidification component 10.

[0072] Therefore, when the humidifying component 10 is in the second working mode, since both the water supply component 20 and the drainage component 40 are in the open state, if the water level in the water storage container 31 continues to drop, it proves that the humidifying component 10 is in a normal working state. If the water level in the water storage container 31 remains stable or continues to rise, it proves that the humidifying component 10 is in an abnormal working state. For example, the humidifying component 10 may become blocked or breed bacteria, which will reduce its humidification efficiency, that is, reduce the consumption of the humidifying component 10, resulting in more water entering the water storage container 31 from the humidifying component 10, and thus the water level in the water storage container 31 will continue to rise.

[0073] When the water level in the water storage component 31 continues to drop, if the current water level in the water storage component 31 is lower than the minimum water level, the water supply component 20 is turned on to continue supplying water to the humidification component 10, ensuring the humidification efficiency of the humidification component 10. Before the current water level in the water storage component 31 reaches the minimum water level, the drainage component 40 can be turned on to drain water while the water supply component 20 is receiving water, preventing the water level in the water storage component 31 from rising continuously. Alternatively, the drainage component 40 can be turned off to reduce the energy consumption of the drainage component 40 before the current water level in the water storage component 31 reaches the minimum water level. At the same time, since water has a certain degree of permeability, the water in the water storage component 31 can be used to achieve a certain degree of humidification of the humidification component 10 through permeation.

[0074] Furthermore, the humidification module 100 has a second working mode. In the second working mode, when the water level in the water storage component 31 reaches or exceeds the maximum water level, the water supply component 20 is in a closed state and the drainage component 40 is in a closed state.

[0075] Therefore, when the water level in the water storage component 31 reaches or exceeds the maximum water level, the water supply component 20 is turned off and the drainage component 40 is turned on to stop the water inflow, while the water in the water storage component 31 can be continuously discharged to avoid the problem of overflow caused by the water level in the water storage component 31 being too high.

[0076] In some embodiments, the humidification module 100 further includes a humidity detection device (not shown in the figure).

[0077] The humidity detection device is used to detect the actual humidity of the environment. When the difference A between the actual humidity and the set humidity is greater than the set difference △A, it enters the second working mode.

[0078] Therefore, by setting a humidity detection device, the humidification module 100 can enter a second working mode based on the relationship between the actual ambient humidity and the set humidity.

[0079] For example, the humidity detection device can be installed on the side of the humidification module 100 facing the indoor side, which facilitates the humidity detection device to detect the humidity of the indoor environment and helps to avoid interference from the humidification module 100 to the humidity detection device.

[0080] In some embodiments, the humidification module 100 further includes a counting device (not shown) and an alarm device (not shown).

[0081] The counting device is used to record the number of consecutive times the water level in the water storage container 31 rises to (i.e. rises to, rather than falls to) the highest water level detected by the highest water level detector 322. The alarm device issues an alarm when the number of consecutive times reaches a predetermined value.

[0082] Therefore, the counting device can record the number of times the water level in the water storage container 31 rises to the highest water level when the highest water level detector 322 detects it, and the alarm device can issue an alarm when the number of consecutive times reaches a predetermined value, so as to remind the user that the humidification module 100 is abnormal, so that the user can repair or replace it in time.

[0083] For example, both the counting device and the alarm device are installed on the controller of the air conditioner, and the alarm device sounds an alarm after three consecutive alarms. The alarm device can sound an alarm, vibrate an alarm, or display an icon representing a malfunction of the humidification component 10 on the display screen of the air conditioner, etc., which is not limited here.

[0084] It should be noted that the three instances mentioned above are for illustrative purposes only and do not represent any limitation.

[0085] In some embodiments, such as Figures 2-5 As shown, the humidification assembly 10 includes a humidifying element 11 and a water supply element 12.

[0086] Specifically, the water supply component 12 is used to supply water to the humidifying component 11. The water supply assembly 20 includes a water supply path 21 and a water supply switch 22. The water supply path 21 is connected to the water supply component 12, and the water supply switch 22 is used to control the opening and closing of the water supply path 21. The water storage component 31 is constructed as a water receiving tray located below the humidifying component 10. The drainage assembly 40 includes a drainage pump 41 and a drainage path 42. The inlet of the drainage pump 41 is connected to the water receiving tray, and the outlet of the drainage pump 41 is connected to the drainage path 42.

[0087] Therefore, by setting up a water supply path 21 and connecting it to the water supply component 12, water in the water supply path 21 can flow to the water supply component 12. By setting up a water supply switch 22, the on / off state of the water supply path 21 can be controlled, thereby realizing the water inlet and water out of the water supply path 21. By setting up a drain pump 41, water in the water storage component 31 can be pumped into the drain path 42 and then discharged through the drain path 42, which helps to reduce the drainage difficulty of the drainage component 40. By controlling the opening and closing of the drain pump 41, the on / off state of the drain path 42 can be controlled, thus eliminating the need to set up structures such as drain switches in the drain path 42, which helps to reduce production costs.

[0088] The water storage component 31 may not be a water receiving tray, but may be a water storage box connected to the water receiving tray, etc., which is not limited here.

[0089] For example, the water supply line 21 is connected to an external water line, such as a faucet, so that the water from the external water line can flow along the water supply line 21 to the water applicator 12, and then from the water applicator 12 to the humidifier 11. The water applicator 12 can be constructed as a water pipe, and the humidifier 11 can be constructed as a wet membrane. A frame 13 is provided on the outside of the wet membrane. The frame 13 is detachably connected to the water storage box, and at least a part of the water applicator 12 extends into the frame 13.

[0090] This facilitates enhancing the structural stability of the humidifying component 11 and the water-applying component 12, and as... Figure 6 As shown, the water pipe is provided with multiple round holes 121 that open toward the wet membrane. The multiple round holes 121 are spaced apart to facilitate drainage to the wet membrane through the multiple round holes 121, thereby achieving water supply to the wet membrane.

[0091] Reference Figure 3 As shown, the water storage box is located below the wet membrane so that the remaining water on the wet membrane can drip or flow into the water storage box under the action of gravity. Thus, the water storage box can store the dripping water of the humidification component 10, and at least part of the wet membrane extends into the water storage cavity of the water storage box. It should be noted that the wet membrane has a certain self-absorption capacity, so the water in the water storage box can permeate and spread along the wet membrane under the self-absorption of the wet membrane, thereby achieving a certain degree of humidification of the wet membrane and improving the humidification efficiency.

[0092] The drain pump 41 is installed in the water storage chamber of the water storage box, and the lowest water level of the water storage box is greater than the inlet height of the drain pump 41, so as to reduce the abnormal noise caused by the drain pump 41 due to unsaturation when it sucks water. In some examples, the distance between the inlet of the drain pump 41 and the inner bottom wall of the water storage box is 4mm to 6mm, such as 4mm, 5mm, 6mm, etc.

[0093] When the distance between the inlet of the drain pump 41 and the inner bottom wall of the water storage box meets the above-mentioned range, the abnormal noise caused by the unsaturated state of the drain pump 41 during water intake can be reduced.

[0094] Furthermore, such as Figure 4 and Figure 5 As shown, the outlet of the drainage pump 41 is connected to the drainage channel 42, which facilitates the drainage pump 41 to discharge water through the drainage channel 42. The drainage channel 42 can be connected to the water receiving pan of the heat exchanger 300, which facilitates the discharge of water into the water receiving pan. Of course, the drainage channel 42 can also be connected to other structures suitable for drainage, which is not limited here.

[0095] In some embodiments, such as Figures 2-5 As shown, the water supply assembly 20 also includes a pressure reducing device 50.

[0096] The pressure reducing device 50 is located in the water supply line 21 and upstream of the water supply switch 22, that is, the pressure reducing device 50 is located on the side of the water supply switch 22 near the inlet of the water supply line 21. Therefore, the pressure reducing device 50 can reduce the pressure of the water entering through the water supply line 21, so that the water flow pressure to the water applicator 12 is constant, thereby improving the uniformity of the water flow to the humidifier 11.

[0097] In some embodiments, the water supply switch 22 includes a plurality of switch valves arranged in series.

[0098] Therefore, multiple switching valves are connected in series so that if one switching valve fails, the other switching valves can still control the on / off of the water supply circuit 21, which helps to improve control accuracy.

[0099] For example, there are two switching valves, and both switching valves are constructed as solenoid valves, which facilitates the improvement of the control accuracy of the water supply circuit 21. Of course, there may be other numbers of switching valves, which are not limited here.

[0100] The present invention also proposes an air handling device 1000.

[0101] An air handling device 1000 according to an embodiment of the present invention includes the humidification module 100 described in any of the above embodiments.

[0102] According to an embodiment of the air handling equipment 1000 of the present invention, the humidification module 100 is equipped with a liquid level detection device 32, and the water supply component 20 and the drainage component 40 can perform corresponding actions according to the detection signal of the liquid level detection device 32. On the one hand, this can avoid the problem of reduced humidification efficiency of the humidification module 100 after long-term use. On the other hand, it makes it easier for users to judge the current status of the humidification module 100 and to repair or replace the humidification module 100 in a timely manner, which helps to reduce the impact on users and enhances the user experience.

[0103] In some embodiments, such as Figure 1 As shown, the air handling unit 1000 has a first air duct 200, the inlet of the first air duct 200 is adapted to communicate with the outdoor side, the outlet of the first air duct 200 is adapted to communicate with the indoor side, a heat exchanger 300 and a humidification component 10 are provided in the first air duct 200, the humidification component 10 is located downstream of the heat exchanger 300, and the air handling unit 1000 also includes a drain pan 301 located below the heat exchanger 300, and a drain component 40 is adapted to drain water into the drain pan 301.

[0104] It should be noted that Figure 1 The dashed lines represent air, and the arrows indicate the direction of airflow.

[0105] Therefore, by placing the humidifying component 10 in the first air duct 200 and downstream of the heat exchanger 300, when the indoor air is dry, the outdoor fresh air passes through the heat exchanger 300 and blows towards the humidifying module 100. The humidifying module 100 humidifies the fresh air, and the humidified air flows into the indoor space, thereby keeping the temperature and humidity of the indoor air intake within a range suitable for human comfort. The drainage component 40 is adapted to drain water into the drainage tray 301 to reduce the drainage difficulty of the drainage component 40.

[0106] For example, the first air duct 200 is an indoor fresh air duct, and an indoor air intake impeller is provided in the first air duct 200. The indoor air intake impeller 501 is located in the first air duct 200 near the air outlet, and the purification module 600, heat exchanger 300, humidification module 100 and indoor air intake impeller 501 are arranged in sequence in the direction of air flow from the outside to the inside.

[0107] Therefore, fresh outdoor air can enter the indoor space through the purification module 600, heat exchanger 300, and humidification module 100 in sequence under the action of indoor air intake impeller 501, so that the temperature and humidity of the indoor air intake are within a range suitable for human comfort.

[0108] Furthermore, such as Figure 1 As shown, the air handling unit 1000 also has a second air duct 400.

[0109] The inlet of the second air duct 400 is adapted to connect with the indoor side, and the outlet of the second air duct 400 is adapted to connect with the outdoor side. The heat exchanger 300 includes a first part and a second part, the first part being located in the first air duct 200 and the second part being located in the second air duct 400.

[0110] For example, an indoor exhaust fan 502 is provided at the entrance of the second air duct 400, so that indoor air can enter the second air duct 400 under the action of the indoor exhaust fan 502 and be discharged to the outside through the outlet of the second air duct 400. Thus, it is convenient to exhaust air to the outside through the second air duct 400.

[0111] The present invention also proposes a control method for a humidification module.

[0112] According to the control method of the humidification module of the present invention, the humidification module 100 includes: a humidification component 10, a water supply component 20, a recovery component 30, and a drainage component 40. The water supply component 20 is used to supply water to the humidification component 10. The recovery component 30 includes a water storage component 31 and a liquid level detection device 32. The water storage component 31 is used to store the dripping water of the humidification component 10. The liquid level detection device 32 is used to detect the water level height of the water storage component 31 and includes a minimum water level detector 321 and a maximum water level detector 322. The drainage component 40 is used to drain water from the water storage component 31. The water supply component 20 and the drainage component 40 both perform corresponding actions according to the detection signal of the liquid level detection device 32. The control method includes: controlling the water supply component 20 and the drainage component 40 to perform corresponding actions according to the detection signal of the liquid level detection device 32.

[0113] Specifically, the water supply component 20 is used to supply water to the humidification component 10, and the recovery component 30 includes a water storage component 31 and a liquid level detection device 32. The water storage component 31 is used to store the dripping water from the humidification component 10, and the liquid level detection device 32 is used to detect the water level height of the water storage component 31, and includes a minimum water level detector 321 and a maximum water level detector 322. The drainage component 40 is used to drain water from the water storage component 31. Both the water supply component 20 and the drainage component 40 are configured to perform corresponding actions according to the detection signal of the liquid level detection device 32.

[0114] Therefore, the water supply component 20 supplies water to the humidification component 10 to ensure that the humidification component 10 has sufficient humidity, thereby ensuring the humidification effect of the humidification component 10 on the fresh air. The water storage component 31 can store the dripping water of the humidification component 10, so that after the humidification component 10 has humidified the air, the remaining water on the humidification component 10 can fall into the water storage component 31 for storage, thereby preventing excessive water from remaining on the humidification component 10 and flowing to other structures, which helps to protect other structures, and can also collect the remaining water on the humidification component 10 to avoid waste.

[0115] The draining device is used to drain water from the water storage device 31, thereby reducing the water level in the water storage device 31 in a timely manner and preventing the water level in the water storage device 31 from being too high and causing overflow.

[0116] Furthermore, the liquid level detection device 32 includes a minimum water level detector 321 and a maximum water level detector 322, wherein both the water supply component 20 and the drainage component 40 are configured to perform corresponding actions based on the detection signals from the liquid level detection device 32. For example, the minimum water level detector 321 and the maximum water level detector 322 can be triggered when the water level in the water storage container 31 reaches the minimum and maximum water level heights, respectively, and both the water supply component 20 and the drainage component 40 are configured to perform corresponding actions based on the triggering status of the minimum water level detector 321 and the maximum water level detector 322. Alternatively, the minimum water level detector 321 and the maximum water level detector 322 can monitor the water level in the water storage container 31 in real time, and both the water supply component 20 and the drainage component 40 are configured to perform corresponding actions based on the real-time detection results of the minimum water level detector 321 and the maximum water level detector 322.

[0117] It should be noted that the minimum water level height in this invention refers to the set minimum water level height, such as the current water level height in the water storage container 31 when the minimum water level detector 321 is triggered, and not the actual minimum water level height that the water in the water storage container 31 can reach. Similarly, the maximum water level height refers to the set maximum water level height, such as the current water level height in the water storage container 31 when the maximum water level detector 322 is triggered, and not the actual maximum water level height that the water in the water storage container 31 can reach.

[0118] Furthermore, such as Figure 7 As shown, the control method is as follows:

[0119] S1: Based on the detection signal from the liquid level detection device 32, control the water supply component 20 and the drainage component 40 to perform corresponding actions.

[0120] For example, the corresponding action is to turn on the water supply component 20 and / or the drainage component 40, which can avoid the problem of excessive water level in the water storage component 31, and also help to avoid the problem of reduced humidification efficiency of the humidification module 100 during long-term use. At the same time, it is convenient for users to judge the current status of the humidification module 100 according to the corresponding action, so as to repair or replace the humidification module 100 in a timely manner, which helps to reduce the impact on the user's use.

[0121] According to the control method of the humidification module of the present invention, the water supply component 20 and the drainage component 40 are controlled to perform corresponding actions based on the detection signal of the liquid level detection device 32. On the one hand, this can avoid the problem of reduced humidification efficiency of the humidification module 100 during long-term use. On the other hand, it makes it easier for users to judge the current status of the humidification module 100 and to repair or replace it in a timely manner, thereby reducing the impact on users and enhancing the user experience.

[0122] Furthermore, such as Figure 7 As shown, the control method for the humidification module includes:

[0123] S2: When the difference A between the actual ambient humidity and the set humidity is less than or equal to the set difference △A, the humidification module 100 is controlled to enter the first working mode.

[0124] S21: After entering the first working mode, when the water level in the water storage component 31 reaches or exceeds the minimum water level, the water supply component 20 is controlled to be in the closed state, and the drainage component 40 is controlled to be in the open state.

[0125] Therefore, when the water level in the water storage component 31 reaches or exceeds the minimum water level, the water supply component 20 is turned off to stop the water supply to the humidification component 10, thus preventing the water level in the water storage component 31 from continuing to rise. At the same time, the water in the water storage component 31 is drained by opening the drainage component 40, thereby reducing the water level in the water storage component 31 and preventing the water level in the water storage component 31 from overflowing due to excessive water level.

[0126] Furthermore, such as Figure 7 As shown, the control method for the humidification module includes:

[0127] S22: After entering the first working mode, when the water level in the water storage component 31 is lower than the minimum water level, the water supply component 20 is turned on and the drainage component 40 is turned off.

[0128] Therefore, when the current water level of the water storage component 31 is lower than the minimum water level, the water supply component 20 is turned on to continuously supply water to the humidification component 10, ensuring the humidification efficiency of the humidification component 10. The drainage component 40 can be turned off to reduce the energy consumption of the drainage component 40 before the current water level of the water storage component 31 reaches the minimum water level. At the same time, since the wet membrane has a certain self-absorption capacity, the water in the water storage box can permeate and spread along the wet membrane under the self-absorption of the wet membrane, thereby achieving a certain degree of humidification of the wet membrane and improving the humidification efficiency.

[0129] In some embodiments, such as Figure 7 As shown, the control method for the humidification module includes:

[0130] S3: When the difference A between the actual ambient humidity and the set humidity is greater than the set difference △A, control the humidification module 100 to enter the second working mode.

[0131] S31: After entering the second working mode, when the water level in the water storage component 31 reaches the minimum water level, or exceeds the minimum water level but does not reach the maximum water level, the water supply component 20 is controlled to be in the open state, and the drainage component 40 is controlled to be in the open state.

[0132] Therefore, when the current water level of the water storage component 31 reaches the minimum water level, or when the current water level of the water storage component 31 is between the minimum and maximum water levels, the water supply component 20 is turned on and the drainage component 40 is turned on, so that while maintaining water intake, the water in the water storage component 31 is drained by turning on the drainage component 40. At this time, the humidification module 100 can work normally.

[0133] It should be noted that when both the water supply component 20 and the drainage component 40 of the humidification module 100 are in the open state, if the water level in the water storage container 31 continues to drop, it proves that the humidification component 10 is in a normal working state. If the water level in the water storage container 31 remains stable or continues to rise, it proves that the humidification component 10 is in an abnormal working state. For example, the humidification component 10 may be blocked or bacteria may grow, which will reduce its humidification efficiency, that is, reduce the consumption of the humidification component 10, resulting in more water entering the water storage container 31 from the humidification component 10, and thus the water level in the water storage container 31 will continue to rise.

[0134] Furthermore, such as Figure 7 As shown, the control method for the humidification module includes:

[0135] S32: After entering the second working mode, when the water level in the water storage component 31 reaches or exceeds the maximum water level, the water supply component 20 is controlled to be in the closed state, and the drainage component 40 is controlled to be in the open state.

[0136] Therefore, when the water level in the water storage component 31 reaches or exceeds the maximum water level, the water supply component 20 is turned off and the drainage component 40 is turned on to stop the water inflow, while the water in the water storage component 31 can be continuously discharged to avoid the problem of overflow caused by the water level in the water storage component 31 being too high.

[0137] Furthermore, such as Figure 7 As shown, the control method for the humidification module includes:

[0138] S33: After entering the second working mode, when the water level in the water storage component 31 is lower than the minimum water level, the water supply component 20 is turned on and the drainage component 40 is turned off.

[0139] Therefore, when the current water level of the water storage component 31 is lower than the minimum water level, the water supply component 20 is in the open state to continue supplying water to the humidification component 10, ensuring the humidification efficiency of the humidification component 10. Before the current water level of the water storage component 31 reaches the minimum water level, the drainage component 40 can be in the closed state to reduce the energy consumption of the drainage component 40. At the same time, since the wet membrane has a certain self-absorption capacity, the water in the water storage box can permeate and spread along the wet membrane under the self-absorption of the wet membrane, thereby achieving a certain degree of humidification of the wet membrane and improving the humidification efficiency.

[0140] In some embodiments, such as Figure 7 As shown, the control method for the humidification module includes:

[0141] S4: Record the number of consecutive times the water level in the water storage unit 31 rises to (i.e. rises to, rather than falls to) the highest water level detected by the highest water level detector 322.

[0142] S5: Issue an alarm when the number of consecutive steps reaches a predetermined value.

[0143] Therefore, the counting device can record the number of times the water level in the water storage unit 31 reaches the highest water level when the highest water level detector 322 detects it, and the alarm device can issue an alarm when the number of consecutive times reaches a predetermined value, so as to remind the user that the humidification module 100 is abnormal, so that the user can repair or replace it in time.

[0144] For example, both the counting device and the alarm device are installed on the controller of the air conditioner. The alarm device can sound an alarm, vibrate, or display an icon representing a malfunction of the humidification component 10 on the display screen of the air conditioner, etc., without limitation.
