Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0047] At present, humidification devices usually use wet film humidification units to humidify the air. When the humidification function is running, a certain water level is maintained in the water tank of the water receiving tray so that the lower end of the wet film can be immersed in the water. When the user turns off the humidification function, there is still a lot of water left in the water tank. Therefore, the wet film humidification unit needs to continue to run for a period of time before shutting down in order to evaporate the water in the water tank. It usually takes more than half an hour, resulting in a longer actual shutdown time of the humidification function.

[0048] In view of this, the present invention proposes a humidifying device, which can be applied to an air conditioner. For example, please refer to Figure 1 , Figure 1 FIG. 1 is a schematic diagram of the structure of an embodiment of an air conditioner 10 of the present invention. The air conditioner 10 includes an indoor unit and an outdoor unit (not shown in the drawings) which are separately arranged. The outdoor unit is installed in an outdoor space. Figure 1 The indoor unit of the air conditioner 10 is shown from a frontal top view, wherein the indoor unit of the air conditioner 10 includes a humidifying device 102 disposed at a lower end thereof and an evaporator device 101 disposed above the humidifying device 102 .

[0049] Of course, the humidifying device 102 of the present application can also be used in a humidifier or a fresh air blower, and the present application does not specifically limit the application of the humidifying device 102.

[0050] Please refer to Figures 1 to 4 In one embodiment of the present invention, the humidifying device 102 has a normal mode and a shutdown acceleration mode. The humidifying device 102 specifically includes a housing 11, a main humidifying unit 12, an auxiliary humidifying unit 13 and a control unit (not shown in the drawings), wherein the housing 11 is provided with a water tank 11a, the main humidifying unit 12 and the auxiliary humidifying unit 13 are arranged in the housing 11 and can use the water in the water tank 11a to humidify the air; the control unit is electrically connected to the main humidifying unit 12 and the auxiliary humidifying unit 13. In the normal mode, the control unit controls the main humidifying unit 12 to operate alone, and in the shutdown acceleration mode, the control unit controls the main humidifying unit 12 and the auxiliary humidifying unit 13 to operate simultaneously.

[0051] The technical solution of the present invention is to add an auxiliary humidifying unit 13 in addition to the main humidifying unit 12. When the user turns off the humidification function, the humidifying device 102 enters a shutdown acceleration mode, and the control unit controls the main humidifying unit 12 and the auxiliary humidifying unit 13 to run simultaneously to speed up the volatilization efficiency of the residual water in the water tank 11a, so that the humidifying device 102 only needs to continue running for a short period of time to evaporate the water in the water tank 11a, thereby greatly shortening the actual shutdown time of the humidification function.

[0052] It can be understood that the auxiliary humidifying unit 13 can also be used when the humidification function is running normally, that is, in some embodiments, the humidifying device 102 can also have a startup acceleration mode. In the startup acceleration mode, the control unit controls the main humidifying unit 12 and the auxiliary humidifying unit 13 to run simultaneously. For example, when the humidifying device 102 is just started, the main humidifying unit 12 and the auxiliary humidifying unit 13 can be controlled to run simultaneously to increase the humidification speed and humidification effect of the humidifying device 102, so that the ambient humidity of the indoor space can reach the preset conditions faster, thereby improving the user experience.

[0053] The main humidification unit 12 has various structural forms, for example, please refer to Figures 2 to 4In one embodiment, the main humidification unit 12 includes a wet film 121 disposed in the water tank 11a, and a fan 122 disposed on one side of the wet film 121. The fan 122 is electrically connected to the control unit and is used to drive air to flow through the wet film 121. That is, the main humidification unit 12 adopts a cold evaporation method, which can increase the contact and interaction area between air and water molecules and improve the humidification speed and effect of the air.

[0054] Of course, in some embodiments, the main humidification unit 12 may also adopt an ultrasonic atomization method, that is, the main humidification unit 12 is configured as an ultrasonic atomizer 131 disposed in the water tank 11a, so that the water mist generated by the ultrasonic atomizer 131 can be directly carried by the air and blown to the indoor space to achieve the purpose of humidifying the indoor space. In other embodiments, the main humidification unit 12 may also include an ultrasonic atomizer 131, a wet film 121 and a fan 122, and the ultrasonic atomizer 131 and the wet film 121 are arranged in sequence in the air inlet direction of the fan 122, so that the water mist generated by the ultrasonic atomizer 131 first wets the wet film 121 to increase the area of ​​contact and interaction between water molecules and air, and under the action of the fan 122, the air first flows through the wet film 121 and then blows to the indoor space. In other embodiments, the main humidification unit 12 may also adopt a thermal evaporation method.

[0055] The auxiliary humidification unit 13 also has various structural forms, for example, please refer to Figures 2 to 4 In one embodiment, the auxiliary humidification unit 13 includes an ultrasonic atomizer 131 disposed in the water tank 11a, and the water mist generated by the ultrasonic atomizer 131 can enter the airflow flowing through the wet film 121. In this embodiment, the wet film 121 through cold evaporation combined with the ultrasonic atomizer 131 can not only ensure the good humidification effect of the humidification device 102 in the normal mode, but also improve the speed of the humidification device 102 in the shutdown acceleration mode to volatilize the residual water in the water tank 11a. The structure is simple and easy to implement, and it is conducive to reducing the manufacturing cost of the humidification device 102. Of course, in some embodiments, the auxiliary humidification unit 13 can also adopt a cold evaporation method, that is, the main humidification unit 12 and the auxiliary humidification unit 13 both adopt the evaporation method of the wet film 121. Further, the wet films 121 of the two can be arranged side by side in the airflow direction, or can be arranged front and back in the airflow direction. In other embodiments, the auxiliary humidification unit 13 can also adopt a thermal evaporation method.

[0056] It is worth mentioning that in the embodiment where the main humidification unit 12 includes an ultrasonic atomizer 131, a wet film 121 and a fan 122, optionally, the ultrasonic atomizer 131 of the main humidification unit 12 is configured as a first ultrasonic atomizer 131, and the auxiliary humidification unit 13 is configured as a second ultrasonic atomizer 131, the first ultrasonic atomizer 131 is arranged on the air inlet side, and the second ultrasonic atomizer 131 is arranged on the air outlet side of the wet film 121. In this way, in the normal mode, the second ultrasonic atomizer 131 does not work, and the water mist generated by the first ultrasonic atomizer 131 is blown to the wet film 121 under the action of the airflow, and then blown to the indoor space to achieve the purpose of indoor humidification; in the shutdown acceleration mode, the first ultrasonic atomizer 131 and the second ultrasonic atomizer 131 work at the same time, and the water mist generated by the second ultrasonic atomizer 131 will not pass through the wet film 121 but will be blown directly to the indoor space.

[0057] Please refer to Figure 3 and Figure 4 In one embodiment, the bottom surface of the water tank 11a is provided with a mounting hole for installing the ultrasonic atomizer 131, and the vibration surface of the ultrasonic atomizer 131 is accommodated in the mounting hole. In this way, the vibration surface can be at the lowest position of the water tank 11a, so that it can also work when the water in the water tank 11a is at the lowest water level, thereby improving the atomization effect of the ultrasonic atomizer 131. In this embodiment, optionally, the outer side surface of the bottom wall of the water tank 11a is provided with a threaded hole, and the ultrasonic atomizer 131 is locked on the threaded hole by screws, so that the installation and disassembly of the ultrasonic atomizer 131 is convenient, and the screws are in a dry working environment and avoid the problem of being easily damaged by water erosion in the water tank 11a. Further optionally, a sealing rubber ring is sandwiched between the ultrasonic atomizer 131 and the mounting hole. Of course, in some embodiments, the ultrasonic atomizer 131 can also be directly arranged on the bottom surface of the water tank 11a. In other embodiments, the ultrasonic atomizer 131 can also be installed on the water tank 11a by welding, riveting or clamping.

[0058] It is understood that the wet film 121 is prone to bacteria when it is in a wet state for a long time. Therefore, after the water in the water tank 11a is evaporated, the humidifying device 102 can continue to operate in the shutdown acceleration mode and maintain the preset time before stopping the operation, so that the wet film 121 changes from a wet state to a dry state. The preset time can be determined according to the material and specification size of the wet film 121, for example, it can be 5 minutes or 10 minutes, and the present application does not make specific limitations here.

[0059] There are many ways to detect whether the water in the water tank 11a has evaporated. For example, in one embodiment, the humidifying device 102 also includes a low water level sensor (not shown in the drawings) provided in the water tank 11a, and the low water level sensor is electrically connected to the control unit. Specifically, the low water level sensor can be configured as any one of a float type water level sensor, a capacitive water level sensor, and a photoelectric water level sensor. Of course, in other embodiments, a pressure sensor can also be provided on the bottom surface of the water tank 11a. When the pressure sensor does not detect a pressure value, it indicates that there is no water on it, that is, the water in the water tank 11a has been substantially evaporated.

[0060] Please refer to Figure 2 In one embodiment, the wet film 121 and the ultrasonic atomizer 131 are both arranged on the air inlet side of the fan 122, and the ultrasonic atomizer 131 is arranged downstream of the wet film 121. In this way, the water mist generated by the ultrasonic atomizer 131 when working will not flow to the wet film 121, but will flow directly to the indoor space after passing through the fan 122. In this way, after the water in the water tank 11a evaporates, the water mist will not affect the drying speed of the wet film 121, thereby further shortening the actual closing time of the humidification function. In addition, the ultrasonic atomizer 131 is arranged downstream of the wet film 121, which can maximize the cross-sectional area of ​​the wet film 121 in the direction perpendicular to the air inlet direction, thereby facilitating the improvement of the humidification effect. Of course, in some embodiments, the ultrasonic atomizer 131 and the wet film 121 can also be arranged on the air inlet side of the fan 122, and the ultrasonic atomizer 131 and the wet film 121 are arranged side by side in the air inlet direction. In other embodiments, the ultrasonic atomizer 131 and the wet film 121 are both arranged on the air outlet side of the fan 122. In the air inlet direction, the ultrasonic atomizer 131 and the wet film 121 are arranged side by side, or the ultrasonic atomizer 131 is arranged downstream of the wet film 121. In the air inlet direction of the fan 122, the ultrasonic atomizer 131 and the wet film 121 are arranged in sequence. In other embodiments, the wet film 121 and the ultrasonic atomizer 131 can also be arranged on the air inlet side and the air outlet side of the fan 122, respectively.

[0061] Please refer to Figure 2 and Figure 3 In one embodiment, the housing 11 includes a water receiving tray 112 and a water tank 113 disposed on the water receiving tray 112. The water tank 11a is formed on the water receiving tray 112. The water tank 113 can supply water to the water tank 11a. The water outlet of the water tank 113 is provided with a water outlet valve 114. In this way, the water replenishment to the water tank 11a can be accurately controlled by the water outlet valve 114, thereby avoiding the problem of too high water level in the water tank 11a. Of course, in some embodiments, the water tank 113 can also pump water to the water tank 11a through a water pump. In other embodiments, the water tank 113 may not be provided, and the humidifying device 102 uses a water pump to directly pump water from an external water source to the top of the wet film 121.

[0062] In one embodiment, the main humidification unit 12 further includes a water pump, which is used to pump the water in the water tank 11a to the top of the wet film 121. In this way, part of the water in the water tank 11a diffuses upward from the bottom of the wet film 121, and at the same time, part of the water is transported to the top of the wet film 121 by the water pump and diffuses downward from the top of the wet film 121, thereby accelerating the water replenishment of the wet film 121, which is beneficial to improving the humidification efficiency and humidification effect. Of course, in other embodiments, the water pump may not be provided, and the lower end of the wet film 121 may be immersed in the water in the water tank 11a, so that the water molecules can automatically diffuse upward.

[0063] Please refer to Figures 1 to 4 In one embodiment, the housing 11 further comprises a base 111, the water receiving tray 112 is detachably connected to the base 111, the water outlet valve 114 is provided with a water outlet hole 114a connected to the water outlet, and a blocking member 114b movably provided on the water outlet hole 114a, the water receiving tray 112 is provided with an avoidance hole 112a corresponding to the blocking member 114b, and the humidifying device 102 further comprises a valve driving module provided on the base 111, and the valve driving module is driven and connected to the blocking member 114b to open and close the water outlet hole 114a. In this embodiment, the water receiving tray 112, the wet film 121 and the water tank 113 are assembled into a module that can be removed from the base 111, so as to facilitate the water tank 113 to be filled with water and the wet film 121 to be repaired and replaced. By arranging the valve driving module on the base 111, the weight of the detachable module can be reduced, thereby facilitating the user's operation. Of course, in some embodiments, the valve driving module can also be arranged on the water receiving tray 112. In other embodiments, the water outlet valve 114 is configured as a solenoid valve, and a pin needle is provided on the base 111 corresponding to the solenoid valve. The pin needle is electrically connected to the control unit and can abut against the positive and negative contact pins of the solenoid valve after the water receiving tray 112 is installed in place.

[0064] Please refer to Figure 1 , Figures 4 to 6In one embodiment, the water outlet is arranged on the lower end surface of the water tank 113 and is located above the water receiving tray 112. The water outlet valve 114 also includes a valve seat 114c covering the water outlet, a push rod 114d slidingly arranged on the valve seat 114c, a water outlet hole 114a is arranged on the valve seat 114c, a blocking member 114b is arranged at one end of the push rod 114d extending into the water outlet hole 114a, and a valve driving module includes a driving member (not shown in the drawings) and an eccentric push block 141 arranged on the rotating shaft of the driving member. The eccentric push block 141 is arranged below the avoidance hole 112a and can push the push rod 114d to move upward. In this way, the structure is simple and easy to implement. Optionally in this embodiment, the water outlet valve 114 also includes an elastic reset member 114e arranged between the valve seat 114c and the push rod 114d, so that the push rod 114d has a tendency to move downward. Of course, in some embodiments, the elastic reset member 114e may not be provided, and the push rod 114d may be reset by the eccentric push block 141. In other embodiments, the water outlet may also be provided on the side of the water tank 113.

[0065] Specifically, the driving member can be configured as one of an electric motor, a pneumatic motor or a hydraulic motor, the elastic reset member 114e can be configured as one of a compression spring, an elastic rubber sleeve or an elastic silicone sleeve, and the sealing member 114b is configured as a sealing rubber ring or a sealing gasket arranged at the end of the push rod 114d.

[0066] Please refer to Figures 4 to 6 In one embodiment, the outer wall of the water outlet is provided with a threaded column, and the valve seat 114c is correspondingly provided with a threaded hole, and the valve seat 114c is detachably connected to the water outlet of the water tank 113 through threaded cooperation. That is, the valve seat 114c can be used as a detachable cover of the water outlet, and after it is removed from the water outlet, the water outlet can be exposed, and the water outlet can be used as a water inlet for users to add water to the water tank 113.

[0067] Please refer to Figure 1 In one embodiment, the base 111 is provided with an installation cavity 111a and a pull-out opening 111b connected to the installation cavity 111a. The water receiving tray 112 is slidably arranged in the installation cavity 111a through a slide rail 112c structure. When the water receiving tray 112 slides from the pull-out opening 111b into the installation cavity 111a, the water tank 113 blocks the pull-out opening 111b. In this way, the water receiving tray 112 and the base 111 are detachably connected through the slide rail 112c structure, which has a simple structure and is easy to operate. Of course, in other embodiments, the water receiving tray 112 can also be detachably connected to the base 111 by screwing or clamping.

[0068] Please refer to Figure 2In one embodiment, the housing 11 further includes a volute air duct 115 disposed on the base 111, the fan 122 is configured as a centrifugal fan 122 and is disposed in the volute air duct 115, an air inlet 111c is disposed on the side of the base 111, and the water receiving tray 112 is disposed between the air inlet 111c and the volute air duct 115. In this way, the structure is compact and is conducive to reducing the width of the humidifier 102. Of course, in other embodiments, the fan 122 can also be configured as an axial flow fan 122 or a cross-flow fan 122, etc.

[0069] For details, please refer to Figure 1 and Figure 2 , wherein the draw-out opening 111b is arranged on the front of the base 111, that is, the draw-out opening 111b is arranged on the front of the air conditioner 10, the housing 11 further comprises a decorative cover 116 with a movable cover provided with the draw-out opening 111b, a slide rail 112c is arranged at the bottom of the water receiving tray 112, and a slide groove is arranged on the bottom surface of the installation cavity 111a corresponding to the slide rail 112c, and the water receiving tray 112 and the water tank 113 and the wet film 121 thereon can move in and out of the draw-out opening 111b along the slide rail 112c together, so as to facilitate the user to add water to the water tank 113 and other operations. Further, the decorative cover 116 is mounted on the base 111 by means of a snap connection, and of course, it can also be mounted on the base 111 by means of a screw connection.

[0070] Please refer to Figure 1 Furthermore, a retractable sliding lock 117 is provided on one side of the draw-out opening 111b, and a locking groove is provided on the water receiving tray 112 corresponding to the sliding lock 117. When the water receiving tray 112 slides into the installation cavity 111a, the sliding lock 117 can lock the locking groove. In this way, the problem of the water receiving tray 112 accidentally slipping out of the installation cavity 111a can be avoided, thereby improving the safety and reliability of the humidifier 102.

[0071] Please refer to Figures 2 to 4 In one embodiment, the water tank 11a includes a first tank section 11b, a water passage 11c, and a second tank section 11d which are connected in sequence, the water outlet valve 114 is arranged in the first tank section 11b, the wet film 121 and the ultrasonic atomizer 131 are arranged in the second tank section 11d, and the wet film 121 is arranged adjacent to the water passage 11c. In this way, the water flowing into the first tank section 11b from the water outlet valve 114 will preferentially flow to the wet film 121 and be absorbed by the wet film 121 after flowing through the water passage 11c, thereby preferentially ensuring the water supply of the wet film 121. Optionally, in this embodiment, the wet film 121 includes a mounting frame and a wet film 121 body arranged in the mounting frame, and the mounting frame is provided with a clearance channel 121a corresponding to the water passage 11c.

[0072] In one embodiment, the water tank 113 includes a first tank portion 113a and a second tank portion 113b that intersect and communicate with each other, the first tank portion 113a is disposed above the wet film 121, the second tank portion 113b is disposed on the side of the wet film 121, and the water outlet valve 114 is disposed in the second tank portion 113b. In this way, the space above the wet film 121 can be fully utilized to increase the volume of the water tank 113 and prevent the humidifying device 102 from being too bulky in the width direction.

[0073] Please refer to Figures 2 to 4 In one embodiment, the humidifying device 102 further includes an air filter unit 15 disposed on the water receiving tray 112, and the air filter unit 15 is disposed upstream of the wet film 121. In this way, the air can be filtered and humidified, thereby providing clean and moist air to the indoor space. In addition, filtering the air first and then humidifying the air can avoid the problem of impurities in the air contaminating the wet film 121. Of course, in other embodiments, the air filter unit 15 may not be added, or the air filter unit 15 may be disposed downstream of the wet film 121. The air filter unit 15 and the wet film 121 are both installed on the water receiving tray 112. As long as the water receiving tray 112 is removed, the replacement operation of the wet film 121 and the air filter unit 15 can be supported at the same time, which can not only simplify the structure of the humidifying device 102, but also facilitate the maintenance and replacement of the wet film 121 and the air filter unit 15. Of course, in other embodiments, the air filter unit 15 can also be disposed separately on the base 111.

[0074] In one embodiment, the water receiving tray 112 is also provided with a mounting groove 112b, and the air filter unit 15 includes a HEPA filter module inserted in the mounting groove 112b, and the HEPA filter module is arranged opposite to and in parallel with the wet membrane 121. It should be noted that parallel means parallel and nearly parallel. In this way, the mounting structure of the HEPA filter module, that is, the mounting groove 112b, is directly formed on the water receiving tray 112, which is not only simple in structure and easy to implement, but also can reduce manufacturing costs. In addition, the HEPA filter module is arranged opposite to and in parallel with the wet membrane 121, which can maximize the use of the layout space and make the HEPA filter module and the wet membrane 121 have a larger cross-sectional area. Of course, in some embodiments, the HEPA filter module and the wet membrane 121 can also be arranged to intersect. In other embodiments, the HEPA filter module is installed on the water receiving tray 112 by screwing or clamping.

[0075] The present invention also proposes an air conditioner, including the aforementioned humidifying device. The specific structure of the humidifying device refers to the above-mentioned embodiment. Since this air conditioner adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0076] Please refer to Figure 7 , Figure 7 The humidifying device structure diagram of the hardware operating environment involved in the embodiment of the present invention is shown in FIG. 1 . The humidifying device may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard), and the optional user interface 1003 may also include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a wireless fidelity (WIreless-FIdelity, WI-FI) interface). The memory 1005 may be a high-speed random access memory (Random Access Memory, RAM) memory, or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk memory. The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0077] Those skilled in the art will understand that Figure 7 The structure shown in the figure does not constitute a limitation on the humidifying device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0078] like Figure 7 As shown, the memory 1005 as a storage medium may include an operating system, a data storage module, a network communication module, a user interface module, and a humidifier control program. Figure 7 In the humidifying device shown, the network interface 1004 is mainly used for data communication with other devices; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the humidifying device of the present invention can be set in the humidifying device, and the humidifying device calls the humidifying device control program stored in the memory 1005 through the processor 1001, and executes the humidifying device control method provided in the embodiment of the present invention.

[0079] Please refer to Figure 8 The present invention further proposes a humidifying device control method, which is applied to the above-mentioned humidifying device. In the first embodiment of the humidifying device control method of the present invention, the humidifying device control method includes step S10 and step S20, which are as follows:

[0080] Step S10: receiving a humidification function closing signal.

[0081] In this embodiment, the humidification function off signal can be a direct command from the user, such as a shutdown command for the air conditioner, or a single command to turn off the humidification function, or it can be an automatic shutoff command generated by the control unit of the humidification device based on whether the detection data meets the conditions. For example, when the control unit determines that the detected indoor humidity value exceeds a preset value, a humidification function off signal is generated.

[0082] Step S20: Control the main humidification unit and the auxiliary humidification unit to operate simultaneously and enter the shutdown acceleration mode.

[0083] In this embodiment, an auxiliary humidifying unit is added in addition to the main humidifying unit. When the user turns off the humidification function, the humidifying device enters a shutdown acceleration mode. The control unit controls the main humidifying unit and the auxiliary humidifying unit to run simultaneously to speed up the volatilization efficiency of the residual water in the water tank, so that the humidifying device only needs to continue running for a short period of time to evaporate the water in the water tank, greatly shortening the actual shutdown time of the humidification function.

[0084] Specifically, when the air conditioner receives a shutdown command, the air conditioner first turns off the cooling mode or the heating mode and retains the humidification function. At this time, the humidification device operates in the shutdown acceleration mode.

[0085] Optionally, in this embodiment, after receiving the humidification function closing signal, the water outlet valve is also synchronously controlled to close to stop the water tank from replenishing water to the water tank. In this way, the water in the water tank can evaporate more quickly.

[0086] Please refer to Fig. 9 In the second embodiment of the humidifier control method of the present invention, based on the first embodiment of the humidifier control method, before the step of receiving the humidification function off signal, the humidifier control method further includes steps S30 and S40, which are as follows:

[0087] Step S30: receiving a humidification function start signal.

[0088] In this embodiment, the humidification function start signal can be a direct command from the user, such as an air conditioner power-on command, or a single command to turn on the humidification function, or it can be an automatic start command generated by the control unit of the humidification device based on whether the detection data meets the conditions. For example, when the control unit determines that the detected indoor humidity value is lower than a preset value, a humidification function start signal is generated.

[0089] Step S40: Control the main humidification unit and the auxiliary humidification unit to run simultaneously and enter the start-up acceleration mode.

[0090] In this embodiment, the auxiliary humidifying unit can also be used when the humidification function is running normally, that is, the humidifying device also has a startup acceleration mode. In the startup acceleration mode, the control unit controls the main humidifying unit and the auxiliary humidifying unit to run simultaneously. Specifically, when the humidification function of the humidifying device is just started, the main humidifying unit and the auxiliary humidifying unit can be controlled to run simultaneously to improve the humidification speed and humidification effect of the humidifying device, so that the ambient humidity of the indoor space can reach the preset conditions faster, thereby improving the user experience.

[0091] Please refer to Fig. 9 In the third embodiment of the humidifier control method of the present invention, based on the aforementioned second embodiment of the humidifier control method, after the step of controlling the main humidification unit and the auxiliary humidification unit to run simultaneously and enter the start-up acceleration mode, the humidification control method further includes steps S50 to S70, which are as follows:

[0092] Step S50: After the startup acceleration mode is controlled to continue for a first preset time, the auxiliary humidifying unit is stopped.

[0093] Specifically, the preset condition may refer to a specific value of the ambient humidity or a range value. For example, the preset condition is set to an ambient humidity greater than or equal to 50%. The preset condition may be a factory default setting or a user-defined setting. Similarly, the first preset time may also be a factory default setting or a user-defined setting. For example, the first preset time is set to 30 minutes. The present application does not specifically limit the preset condition and the first preset time.

[0094] The detection of ambient humidity can be achieved through a humidity sensor. Specifically, the humidity sensor can be configured by a humidifying device, an air conditioner, or other smart home devices that can wirelessly communicate with the control unit of the humidifying device, as long as it can detect the actual ambient humidity of the indoor space.

[0095] Step S60: Determine whether the ambient humidity reaches a preset condition.

[0096] Step S71: If the ambient humidity does not reach the preset condition, the main humidification unit is operated alone until the ambient humidity reaches the preset condition;

[0097] Step S72: If the ambient humidity reaches a preset condition, a humidification function shut-off signal is generated.

[0098] In this embodiment, when the humidification function is just started, the main humidification unit and the auxiliary humidification unit are controlled to run simultaneously to improve the humidification speed and humidification effect of the humidification device, so that the ambient humidity of the indoor space can reach the preset condition more quickly. It can be understood that the power required to run the main humidification unit and the auxiliary humidification unit at the same time is relatively large, and the ambient humidity has been improved after a period of humidification operation. Therefore, after the start-up acceleration mode continues for the first preset time, only the main humidification unit is run, which is beneficial to energy saving and environmental protection.

[0099] Please refer to Fig. 9 In the fourth embodiment of the humidifier control method of the present invention, based on the first embodiment of the humidifier control method, after the step of controlling the main humidification unit and the auxiliary humidification unit to run simultaneously and enter the shutdown acceleration mode, the humidification control method further includes steps S80 and S90, which are as follows:

[0100] Step S80: receiving a low water level signal from the water tank.

[0101] In this embodiment, the humidifying device further includes a low water level sensor provided in the water tank, the low water level sensor is electrically connected to the control unit, and is used to generate a low water level signal. Specifically, the low water level sensor can be configured as any one of a float type water level sensor, a capacitive water level sensor, and a photoelectric water level sensor. Of course, in other embodiments, a pressure sensor electrically connected to the control unit can be provided on the bottom surface of the water tank, and when the pressure sensor does not detect a pressure value, that is, when there is no water on the pressure sensor, a low water level signal is generated.

[0102] Step S90: After the shutdown acceleration mode is controlled to last for a second preset time, the main humidification unit and the auxiliary humidification unit are stopped.

[0103] In this embodiment, the low water level signal indicates that the water in the water tank has basically evaporated, that is, there is almost no residual water in the water tank. At this time, since the wet film is still in a wet state, continuing to stop the acceleration mode for a period of time can make the wet film drier, thereby reducing the risk of bacteria breeding due to moisture in the wet film. Of course, in other embodiments, the humidification device can be directly turned off after receiving the low water level signal of the water tank, or only the main humidification unit can be operated after receiving the low water level signal of the water tank.

[0104] The second preset time may be a factory default setting or a user-defined setting. For example, the first preset time is set to 5 minutes, which is not specifically limited in this application. It is understood that when the second preset time is a factory default setting, a reasonable second preset time may be calculated based on the size of the wet film and the volume of residual water in the water tank when the water tank is at a low water level.

[0105] The present invention further proposes a storage medium, wherein the storage medium stores a humidifier control program. When the humidifier control program is executed by a processor, the steps of the aforementioned humidifier control method can be implemented.

[0106] The above descriptions are only optional embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention's specification and drawings, or directly / indirectly applied in other related technical fields, are included in the patent protection scope of the present invention.
