When the outdoor air flows through the adsorption area of ​​the adsorption unit, the moisture in the air is adsorbed by the adsorption material, and the dry air is discharged outdoors; after the air on the humidification side is heated by the heater, it flows through the desorption area of ​​the adsorption unit, and the moisture in the adsorption material is desorbed into the air. The humidified air is sent into the room for humidification. In this way, the moisture in the outdoor air is introduced into the room by the humidifying device, the indoor humidity is increased, and the user's comfort is improved.

[0066] See also Figures 2 to 4The humidifying device 100 includes an adsorption unit 30 and a reversing valve 40. The reversing valve 40 is used to adjust the flow direction of the airflow flowing through the adsorption unit 30. The reversing valve 40 has a first working state and a second working state. In the first working state, the first area 31 absorbs moisture, and the second area 32 releases moisture. The outdoor airflow flows through the first area 31, and flows to the outdoors after being absorbed by the adsorption unit 30. Another part of the airflow flows through the second area 32, and flows to the indoor after desorbing the moisture in the adsorption unit 30. In the second working state, the first area 31 releases moisture, and the second area 32 absorbs moisture. The outdoor airflow flows through the second area 32, and flows to the outdoors after being absorbed by the adsorption unit 30. Another part of the airflow flows through the first area 31, and flows to the indoor after desorbing the moisture in the adsorption unit 30.

[0067] In this embodiment, the humidifier 100 uses a reversing valve 40 to achieve simultaneous moisture absorption and dehumidification of the adsorption unit 30 in a simple and reliable structure without moving the adsorption unit 30, thereby extending the service life of the humidifier 100.

[0068] Please continue reading Figure 2 , Figure 5 and Figure 6 The humidifying device 100 includes a shell 10, an adsorption unit 30 and a reversing valve 40. The shell 10 is provided with a first air inlet 11, a second air inlet 12, an outdoor air outlet 13 and an indoor air supply outlet (not shown in the figure). A moisture absorption duct 21 connected to the outdoor air outlet 13 and a humidification duct 20 connected to the indoor air supply outlet are formed in the shell 10. The moisture absorption duct 21 can be selectively connected to one of the first air inlet 11 and the second air inlet 12. The humidification duct 20 can be selectively connected to the other of the first air inlet 11 and the second air inlet 12. The adsorption unit 30 is arranged in the shell 10. The adsorption unit 30 has a first area 31 and a second area 32. An area 31 is connected to the first air inlet 11 so that the air flow flowing into the shell 10 through the first air inlet 11 flows through the first area 31, and the second area 32 is connected to the second air inlet 12 so that the air flow flowing into the shell 10 through the second air inlet 12 flows through the second area 32. The reversing valve 40 is arranged on the shell 10, and the reversing valve 40 has a first working state and a second working state. In the first working state, the first air inlet 11 is connected to the humidification air duct 20, and the second air inlet 12 is connected to the moisture absorption air duct 21. In the second working state, the second air inlet 12 is connected to the humidification air duct 20, and the first air inlet 11 is connected to the moisture absorption air duct 21.

[0069] In one embodiment, please continue to refer to Figure 2 In order to take the moisture in the adsorption unit 30 away and send it to the room, please refer to Figure 2The humidifying device 100 further includes a first heating unit 73 and a second heating unit 74. The first heating unit 73 is used to heat the airflow flowing to the first area 31, and the second heating unit is used to heat the airflow flowing to the second area 32. The first heating unit 73 and the second heating unit 74 can be arranged inside the housing 10, or outside the housing 10, or in the adsorption unit 30, as long as the humidified airflow flowing to the adsorption unit 30 can be heated, and the heated airflow can take away the moisture in the adsorption unit 30. In this way, according to the connection with the humidification air duct 20, the first heating unit 73 or the second heating unit 74 can be turned on to heat the airflow temperature flowing through the desorption zone of the adsorption unit 30, so that the moisture in the adsorption material is fully released under high temperature conditions and flows into the room with the airflow, thereby increasing the indoor humidity and improving the user comfort. A first air inlet channel 22 and a second air inlet channel 23 are formed in the shell 10. The first air inlet 11 is connected to the first area 31 through the first air inlet channel 22, and the second air inlet 12 is connected to the second area 32 through the second air inlet channel 23. The first heating part 73 is arranged in the first air inlet channel 22, and the second heating part 74 is arranged in the second air inlet channel 23.

[0070] In order to ensure that the air flows according to the above design, in one embodiment, a fan can also be provided. The fan can be provided inside the housing 10 or outside the housing 10, as long as it can drive the airflow to flow indoors in the humidification air duct 20 and to flow outdoors in the moisture absorption air duct 21. Figure 2 The humidifying device 100 also includes a moisture absorption side fan 24 and a humidifying side fan 25. The moisture absorption side fan 24 is arranged in the moisture absorption air duct 21 to drive the air flow in the moisture absorption air duct 21 to flow to the outdoor exhaust port 13. The humidifying side fan 25 is arranged in the humidifying air duct 20 to drive the air flow in the humidifying air duct 20 to flow to the indoor air supply port. The moisture absorption side fan 24 or the humidifying side fan 25 can be specifically set as needed to achieve the control of the size and direction of the air flow in the humidifying air duct 20 and the moisture absorption air duct 21. For example, it can be an axial flow fan or a centrifugal fan. In the present embodiment, the humidifying device 100 is arranged in the outdoor unit of the air conditioner, and is connected to the indoor through the humidifying air duct, and has a high wind pressure requirement, so the humidifying side fan 25 is preferably a centrifugal fan. The moisture absorption side fan 24 can be a DC fan with an adjustable speed ranging from 600 to 1500 r / min, preferably 1200 r / min, or an AC fan running at a configured fixed speed. The humidification side fan 25 can be a DC fan with an adjustable speed ranging from 2000 to 4500 r / min, preferably 3500 r / min, and the speed can also be determined according to the type and length of the humidification air duct connecting the indoor and outdoor, which can be determined by experiments.

[0071] The specific structure of the reversing valve 40 can be various, for example, it can be a valve or solenoid valve separately arranged at each air outlet, or it can be an integrated valve. Figures 2 to 6 The reversing valve 40 includes a rotating shaft, and the reversing valve 40 is rotatably installed on the housing 10 around the rotating shaft to switch between the first working state and the second working state.

[0072] Based on the above hardware structure, an embodiment of a control method of the humidifying device 100 of the present invention is proposed.

[0073] Reference Figure 7 , Figure 7 1 is a flow chart of a first embodiment of a control method for a humidifying device 100 of the present invention, and provides a first embodiment of a control method for a humidifying device 100 of the present invention.

[0074] Step S100: when the humidifying device 100 is running, determining whether a preset switching condition is met;

[0075] It should be noted that the executor of this embodiment is the humidification control device, and this embodiment does not limit this.

[0076] It should be understood that the operation of the humidifying device 100 refers to the operation of the humidifying device 100 in the humidification mode. In the humidification mode, one of the first area 31 and the second area 32 of the adsorption unit 30 absorbs moisture, and the other dehumidifies. After a period of time, the moisture in the adsorption material in the adsorption area for absorbing moisture in the adsorption unit 30 is saturated, and the moisture in the adsorption material in the desorption area for dehumidification is basically lost, so it is necessary to swap the adsorption area and the desorption area on the adsorption unit 30. The saturated adsorption material, that is, one of the first area 31 and the second area 32 is switched to the humidification duct 20 for dehumidification, and the heated airflow flows through the adsorption material with sufficient moisture and is sent to the room, while the other of the first area 31 and the second area 32, that is, the adsorption material after moisture loss, is switched to the moisture absorption duct 21, and the outdoor air flow flows through this area, so that the adsorption material in this area absorbs moisture in the outdoor air. In this embodiment, the positions of the adsorption zone and the desorption zone can be swapped by the switching action of the reversing valve 40 , that is, the reversing valve 40 switches between the first working state and the second working state, without moving the adsorption unit 30 .

[0077] Further, in order to improve the humidification efficiency and reduce the number of switching times of the reversing valve 40. The switching action should be performed only when the preset switching conditions are met to achieve the purpose of energy saving and quietness. The preset switching conditions can be pre-set by the system, or can be determined according to the actual water content of the adsorption material in the first area 31 and the second area 32 of the adsorption unit 30. For example, temperature and humidity sensors can be respectively set in the first area 31 and the second area 32 of the adsorption unit 30 to detect the water content of the air after passing through the adsorption material in the corresponding area. The system obtains the water content value, and when the water content of the air after passing through the adsorption material of the hygroscopic air duct 21 is close to stable, or when the water content of the air after passing through the adsorption material of the humidifying air duct 20 is close to stable, it is considered that the hygroscopic material should be adsorbed saturated or completely desorbed, and it is judged that the preset switching conditions are met. In other embodiments, it is also possible to judge whether the preset switching conditions are met based on the duration of the operation of the reversing valve 40 in the first working state or the second working state. This embodiment will be described below.

[0078] Step S200: When the preset switching condition is reached, the switching action of the reversing valve 40 is executed so that the reversing valve 40 is switched from the current working state to another working state, wherein the current working state is one of the first working state and the second working state, and the other working state is the other of the first working state and the second working state.

[0079] It should be understood that when the humidifying device 100 is operated in the humidifying mode, the reversing valve 40 should be in one of the first working state or the second working state. The working state of the reversing valve 40 at the current moment is the current working state. When the preset switching condition is reached, the reversing valve 40 performs the switching action of the reversing valve 40, so that the reversing valve 40 switches from the current working state to another working state, wherein the current working state is one of the first working state and the second working state, and the other working state is the other of the first working state and the second working state.

[0080] The specific structure of the reversing valve 40 can be various, and the switching action of the reversing valve 40 is set according to the specific structure of the reversing valve 40. For example, the reversing valve 40 can be composed of a plurality of valve bodies arranged in the air path. In the present embodiment, the reversing valve 40 is rotatably arranged on the housing 10, and the reversing valve 40 can perform the switching action by rotating between positions corresponding to the first working state and the second working state. When the preset switching condition is reached, the switching action of the reversing valve 40 is performed, so that the reversing valve 40 switches between the first working state and the second working state, and the adsorption unit 30 itself does not move, but changes the structure of the air duct to guide the flow direction of the airflow flowing to the adsorption unit 30. Specifically, the air path that originally flows through the first area 31 and then flows to the outside is changed to flow through the second area 32, and the air path that flows through the second area 32 and flows to the indoor is changed to flow through the first area 31, or the air path that originally flows through the second area 32 and then flows to the outside is changed to flow through the first area 31, and the air path that flows through the first area 31 and flows to the indoor is changed to flow through the second area 32.

[0081] In the first embodiment, the positions of the adsorption zone and the desorption zone can be swapped by the switching action of the reversing valve 40, and the switching action of the reversing valve 40 is that the reversing valve 40 switches between the first working state and the second working state, without moving the adsorption unit 30. Thus, deformation failure caused by the movement of the adsorption unit 30 is avoided, and the service life of the humidifier 100 is extended.

[0082] Reference Figure 8 , Figure 8 The flowchart of the second embodiment of the control method of the humidifying device 100 of the present invention is based on the above Figure 7 The first embodiment shown provides a second embodiment of the control method of the humidifying device 100 of the present invention.

[0083] In the second embodiment, after step S200, the following steps are included:

[0084] Step S300: Return to the step of determining whether a preset switching condition is met when the humidifying device 100 is running.

[0085] It should be understood that after the reversing valve 40 is switched from the current working state to another working state, after a period of time, the adsorption material in the moisture absorption air duct 21 of the adsorption unit 30 is saturated with water, and the adsorption material in the humidification air duct 20 is dehydrated and dried, and the reversing valve 40 needs to be switched to this working state to exchange the positions of the adsorption zone and the desorption zone to achieve continuous humidification. To this end, after the reversing valve 40 switches the working state, it returns to the step of determining whether the preset switching condition is met when the humidifying device 100 is running, and the reversing valve 40 is switched again when the preset switching condition is met, and this cycle is repeated to achieve continuous humidification.

[0086] In the second embodiment, after each switching of the working state of the reversing valve 40 , the process returns to the step of determining whether the switching condition is met, thereby achieving continuous humidification.

[0087] Reference Fig. 9 , Fig. 9 The flowchart of the third embodiment of the control method of the humidifying device 100 of the present invention is based on the above Figure 8 The second embodiment shown provides a third embodiment of the control method of the humidifying device 100 of the present invention.

[0088] In the third embodiment, the step S200 includes:

[0089] Step S21: when the preset switching condition is reached, one of the first heating unit 73 and the second heating unit 74 that is working is controlled to stop working, and timing is started to calculate the delay time T1;

[0090] The humidifying device 100 provided by the present invention includes a first heating part 73 and a second heating part 74. When the humidifying device 100 is in operation, one of the first heating part 73 and the second heating part 74 is turned on, and the airflow passing through the humidifying air duct 20 is heated by the turned on first heating part 73 or second heating part 74, so that when the heated airflow flows through the adsorption unit 30, the adsorption material is dehumidified in a high temperature environment, and the airflow takes away the moisture desorbed by the adsorption material and is sent to the room, so as to achieve the purpose of humidifying the indoor air. When the reversing valve 40 switches the working state, it is obviously necessary to close the working first heating part 73 or the second heating part 74, and then turn on a heating part or the second heating part 74 that was not working before, so as to adapt to the switching of the air duct structure.

[0091] Furthermore, considering that in actual applications, it generally takes a certain amount of time for the heating component to cool down, and the air temperature in the air duct corresponding to the heating component has not yet dropped after the first heating part 73 or the second heating part 74 of the heating component stops working, if the working state of the reversing valve 40 is switched immediately in a short time, the air temperature in the moisture absorption air duct 21 will be too high, taking away the moisture in the adsorption area of ​​the adsorption unit 30, affecting the humidification efficiency, and causing energy waste. For this reason, in this embodiment, after the working first heating part 73 or the second heating part 74 stops working, it takes a period of time for the air in the air duct to cool down before the reversing valve 40 switches from the current working state to another working state.

[0092] Specifically, after one of the first heating unit 73 and the second heating unit 74 that is working is controlled to stop working, timing is started to calculate the delay time T1.

[0093] Step S22: When the delay time T1 reaches the preset delay limit Ta, the reversing valve 40 is controlled to switch from the previous working state to the other working state;

[0094] It should be noted that the preset delay limit value Ta can be preset by the air conditioner manufacturer, and should be determined according to the cooling time required by the first heating part 73 or the second heating part 74. A reliable delay limit value Ta can be obtained through experiments. In one embodiment, the value range of the delay limit value Ta is greater than or equal to 10s and less than or equal to 60s, and the delay limit value Ta is preferably 20s. That is, after the working first heating part 73 or the second heating part 74 stops working for 20s, the reversing valve 40 performs its own switching action, switching from one of the first working state and the second working state to the other.

[0095] Step S23: controlling to turn on the other one of the first heating unit 73 and the second heating unit 74 .

[0096] It should be understood that after the reversing valve 40 switches the working state, the air in the humidification air duct 20 needs to be heated to a set temperature in order to desorb the moisture in the adsorption material and deliver the moisture into the room to achieve a humidification effect.

[0097] In the third embodiment, before the reversing valve 40 switches the working state, the first heating part 73 or the second heating part 74 that is in operation is controlled to stop working, and after a preset time period, the reversing valve 40 switches from the current working state to another working state. In this way, it is avoided that the working state of the reversing valve 40 is switched too quickly, resulting in excessive temperature in the moisture absorption air duct 21, taking away moisture in the adsorption material in the adsorption area, affecting the humidification efficiency and wasting energy.

[0098] Reference Fig.10 , Fig.10 The flowchart of the fourth embodiment of the control method of the humidifying device 100 of the present invention is based on the above Figure 8 The second embodiment shown provides a fourth embodiment of the control method of the humidifying device 100 of the present invention.

[0099] In the fourth embodiment, the step S200 includes:

[0100] S201: When the preset switching condition is reached, one of the first heating unit 73 and the second heating unit 74 that is working is controlled to stop working, and timing is started to calculate the delay time T1;

[0101] Based on the same reason as the third embodiment, before the reversing valve 40 switches the working state, the first heating part 73 or the second heating part 74 that is working is closed first, and the working state of the reversing valve 40 can be switched after a preset time limit Ta.

[0102] S202: When the delay time T1 reaches the preset delay limit Ta, the moisture absorption side fan 24 is controlled to stop working;

[0103] It should be understood that the reversing valve 40 may cause cross-wind between the dehumidification air duct 21 and the humidification air duct 20 during the switching process. If the dehumidification side fan 24 and the humidification side fan 25 work at the same time, the moist airflow in the humidification air duct 20 may merge into the dehumidification air duct 21 and be discharged to the outside, and / or the dry airflow in the dehumidification air duct 21 may mix into the humidification air duct 20, causing fluctuations in indoor humidity.

[0104] To this end, after shutting down the first heating part 73 or the second heating part 74 that is in operation and after the preset time limit Ta has passed, it is also necessary to shut down the desiccant side fan 24 and / or the humidifying side fan 25 before the reversing valve 40 can be switched to another working state to avoid indoor humidity fluctuations.

[0105] Furthermore, since the time required for stopping and starting the fan is relatively long, if the humidification side fan 25 is turned off, the humidified airflow cannot be continuously delivered to the room, which has a significant impact on the humidification effect. Therefore, in this embodiment, only the moisture absorption side fan 24 is turned off, while the humidification side fan 25 is continuously operated. In this way, the occurrence of cross-flow can be reduced, and the humidified airflow can be continuously delivered to the room, the humidification effect is relatively stable, and the indoor personnel feel more comfortable.

[0106] S203: Controlling the reversing valve 40 to switch from the current working state to the other working state;

[0107] In this step, after the moisture absorption side fan 24 is completely stopped, the reversing valve 40 is switched from the current working state to the other working state. Specifically, the speed of the suction side fan can be obtained, and when the speed of the suction side fan is lower than a threshold, the working state of the reversing valve 40 is switched. It is also possible to delay the operation, that is, after the suction side fan shutdown instruction is issued, the working state of the reversing valve 40 is switched after a preset time period.

[0108] S204: Control the moisture absorption side fan 24 to start working, and control the other one of the first heating part 73 and the second heating part 74 to start.

[0109] After the reversing valve 40 is switched, that is, the desiccant air duct 21 and the humidification air duct 20 are completely separated, the desiccant side fan 24 and the other of the first heating part 73 and the second heating part 74 are controlled to open, so that the adsorption unit 30 continues to perform adsorption and desorption actions.

[0110] In the fourth embodiment, before the reversing valve 40 switches the working state, the first heating part 73 or the second heating part 74 that is in operation is controlled to stop working, and after a preset time period, the suction side fan is controlled to stop working, and then the reversing valve 40 is switched from the current working state to another working state. In this way, cross-flow between the dehumidification air duct 21 and the humidification air duct 20 is avoided, which causes excessive fluctuations in indoor temperature and humidity and affects the comfort of indoor users.

[0111] Reference Fig.11 , Fig.11 The flowchart of the fifth embodiment of the control method of the humidifying device 100 of the present invention is based on the above Figures 7 to 10 The first to fourth embodiments shown herein provide a fifth embodiment of the control method of the humidifying device 100 of the present invention.

[0112] In the fifth embodiment, before step S100, the following steps are included:

[0113] S11: Obtaining the continuous working time T2 of the reversing valve 40 in the current working state;

[0114] It should be noted that the current working state is one of the first working state and the second working state. The continuous working time T2 of the reversing valve 40 in the current working state refers to the continuous working time from the start of the moisture absorption device to the first switching of the working state of the reversing valve 40, or the continuous working time from the last switching of the working state of the reversing valve 40 to the next switching of the working state. During the continuous working time T2, the reversing valve 40 maintains the first working state or the second working state. If the duration is too long, the adsorption material in the adsorption unit 30 will be saturated with water or dehydrated and dried. If the working state is not adjusted in time, the humidification effect will be affected. For this reason, when the continuous working time T2 reaches the preset continuous working time limit Tb, it is judged that the preset switching condition is met, and the reversing valve 40 can perform the switching action.

[0115] S12: When the continuous working time T2 reaches a preset continuous working time limit Tb, it is determined that a preset switching condition is met.

[0116] In this step, the continuous working time limit Tb can be preset by the air conditioner manufacturer, and should be determined specifically according to the time required for the adsorption unit 30 to adsorb and desorb moisture, and a reliable continuous working time limit Tb can be obtained through experiments. In one embodiment, the value range of the working time limit Tb is greater than or equal to 60s and less than or equal to 150s, and preferably the working time limit Tb is 120s. That is, when the continuous working time of the reversing valve 40 in the current working state reaches 120s, the reversing valve 40 performs a switching action, switching from one of the first working state and the second working state to the other.

[0117] In the fifth embodiment, the continuous working time of the reversing valve 40 in the current working state is used as the basis for judging whether the preset switching condition is met, and no additional humidity sensor is required. The judgment is simple, the reliability is good, and the cost is lower.

[0118] Reference Fig.12 , Fig.12 The sixth embodiment of the control method of the humidifying device 100 of the present invention is a flow chart of the sixth embodiment of the control method of the humidifying device 100 of the present invention. Fig.11 The fifth embodiment shown provides a sixth embodiment of the control method of the humidifying device 100 of the present invention.

[0119] In the sixth embodiment, before step S100, the following steps are included:

[0120] S101: when the humidifying device 100 is powered on, the current position of the reversing valve 40 is obtained, and if the current position of the reversing valve 40 does not conform to a preset working state, the reversing valve 40 is switched from the current position to a preset working state, and the preset working state is one of the first working state and the second working state;

[0121] In this step, the current position refers to the working position of the reversing valve 40 when it is powered on. It should be understood that when the humidifying device 100 is powered on, the working position of the reversing valve 40 may not be at the position corresponding to the first working state or the second working state, but is between the two. At this time, if the reversing valve 40 is not switched to the preset working state, the humidifying device 100 will not operate properly. And it is also impossible to determine which of the first heating part 73 or the second heating part 74 is turned on. For this reason, the reversing valve 40 can be switched from the current position to the preset working state, which is one of the first working state and the second working state, so that the reversing valve 40 is in the preset first working state or the second working state.

[0122] Furthermore, in this way, the system does not need to determine whether the first heating part 73 or the second heating part 74 should be turned on, but can turn on one of the first heating part 73 or the second heating part 74 according to preset rules, thereby reducing the steps of judgment and detection and saving program resources.

[0123] S102: Control the humidifying device 100 to start running.

[0124] In this step, controlling the humidification device 100 to start operating may include controlling the moisture absorption side fan 24 and the humidification side fan 25 to start working, and controlling one of the first heating part 73 or the second heating part 74 to start.

[0125] In the sixth embodiment, each time the humidifying device 100 is turned on, the reversing valve 40 is first switched to a preset working state, which is beneficial to the normal operation of the humidifying device 100, and one of the first heating part 73 or the second heating part 74 can be turned on according to preset rules, thereby reducing the judgment and detection steps and saving program resources.

[0126] Reference Fig.13 , Fig.13 The flowchart of the seventh embodiment of the control method of the humidifying device 100 of the present invention is based on the above Fig.12 The sixth embodiment shown is a seventh embodiment of the control method of the humidifying device 100 of the present invention.

[0127] In the seventh embodiment, after step S102, the following steps are included:

[0128] S103: Obtain the current indoor humidity value M2;

[0129] It should be noted that the current indoor humidity value M2 is the current indoor air humidity value. It should be understood that obtaining the indoor air humidity may be receiving detection information uploaded by a humidity sensor installed at a preset position, and determining the indoor air humidity according to the detection information. The preset position may be pre-set by the manufacturer of the air conditioner, for example, the preset position may be the air outlet of the indoor unit, and this embodiment is not limited thereto.

[0130] S104: Compare the current indoor humidity value M2 with the preset humidity value M1 set by the system;

[0131] It should be noted that the preset humidity value M1 can be set by the user or determined by the system according to the ambient temperature and humidity. For example, the user can set the preset humidity value through the air conditioner remote control, or it can be pre-set by the air conditioner manufacturer. The preset humidity value M1 can be between 30% and 60%, for example, 50%.

[0132] S1051: When the current indoor humidity value M2 is greater than the preset humidity value M1 plus the first preset difference d1, the humidifying device 100 is controlled to stop running;

[0133] S1052: When the current indoor humidity value M2 is greater than the preset humidity value M1 minus the second preset difference d2, the humidifying device 100 is controlled to start running.

[0134] It should be noted that the first preset difference d1 and the second preset difference d2 can be set by the user or by the system, and the purpose is to stabilize the indoor humidity within a certain range and avoid frequent opening or closing of the humidifier 100.

[0135] The humidifying device 100 can be in a continuous humidifying mode, and the humidifying device 100 keeps running regardless of the indoor relative humidity until a stop signal is received. However, this may cause the indoor relative humidity to be too high, and the indoor user experience is uncomfortable.

[0136] In the seventh embodiment, the user or the system can set the indoor relative humidity to a specific value, for example, 50%. When the indoor relative humidity is lower than 50%-d1, d1 is 5%, it is 45%, and humidification is started; when the indoor relative humidity is higher than 50%+d2, d2 is 3%, it is 53%, and humidification is stopped. In this way, the indoor humidity is maintained in a relatively stable range, making the indoor user experience more comfortable.

[0137] In addition, an embodiment of the present invention further proposes a storage medium, on which a control program of the humidifier device 100 is stored. When the control program of the humidifier device 100 is executed by a processor, the steps of the control method of the humidifier device 100 as described above are implemented.

[0138] In addition, an embodiment of the present invention also proposes a humidification control device, which includes: a memory, a processor, and a humidification device 100 control program stored in the memory and executable on the processor, and when the humidification device 100 control program is executed by the processor, the steps of the control method of the humidification device 100 as described above are implemented.
