[0033] The principles and features of the present application are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present application and are not used to limit the scope of the present application.

[0034] like Figures 1 to 13 As shown, an embodiment of the present application provides a humidifying device, including: a heating water tank 1 and a heater 2.

[0035] The upper part of the heating water tank 1 is provided with a mounting opening 13. The heater 2 includes a wiring portion 21 and a heating portion 22 connected to the wiring portion 21. The wiring portion 21 is at least partially located outside the heating water tank 1, covers the mounting opening 13, and is configured to be electrically connected to the power supply module. The heating portion 22 is configured to penetrate the mounting opening 13 and be inserted into the heating water tank 1, and is configured to heat the water in the heating water tank 1 so that the heating water tank 1 can output steam.

[0036] The humidifying device provided by the embodiment of the present application generates steam by heating water with a heater 2 to meet the humidifying requirements, has no problem of bacterial growth, and has a relatively high cleanliness. Moreover, compared with the scheme in which the heater 2 is inserted upward from the bottom of the heating water tank 1 or horizontally inserted from the side of the heating water tank 1, in this scheme, the heater 2 is inserted downward from the upper part of the heating water tank 1, and the water in the heating water tank 1 is not likely to reach the installation port 13, so the problem of water leakage is not likely to occur.

[0037] Among them, the number of heaters 2 can be one or more. Correspondingly, the number of installation ports 13 can be one or more.

[0038] In some exemplary embodiments, as Figures 2 to 6 shown, the upper part of the heating water tank 1 includes a horizontally arranged first installation surface 11, and the installation port 13 is arranged on the first installation surface 11 so that the heating part 22 can be inserted into the heating water tank 1 in the vertical direction.

[0039] In this scheme, the structure of the heating water tank 1 is relatively simple and regular, which is convenient for processing and forming, and also convenient for the installation of the heater 2.

[0040] In some embodiments, as Figure 7 shown, the distance C1 between the lower end of the heating part 22 and the inner bottom wall of the heating water tank 1 can be, but is not limited to, in the range greater than or equal to 10 mm, which is beneficial to avoiding the direct heating of the inner bottom wall of the heating water tank 1 by the heater 2, resulting in the deformation or softening of the heating water tank 1 and affecting the strength of the heating water tank 1.

[0041] In some embodiments, the heating part 22 is arranged in a columnar structure (such as a cylindrical structure or a prismatic structure), and the lower end of the heating part 22 is lower than the set highest liquid level of the heating water tank 1 to ensure that the heating part 22 can contact the water and then heat the water. A rated water level line can be set in the heating water tank 1, and the set highest liquid level is the liquid level flush with the rated water level line.

[0042] As Figure 7 shown, the length of the heating part 22 is denoted as B1, the liquid level height of the set highest liquid level of the heating water tank 1 is denoted as E1, the distance between the lower end of the heating part 22 and the set highest liquid level is denoted as D1, and D1 / B1 ≤ 0.9, E1 / B1 ≤ 0.8. D1 is the length of the heating part 22 inserted below the liquid level.

[0043] Such a setting is beneficial to avoiding the too high liquid level height in the heating water tank 1 or the too small distance between the liquid surface and the installation port 13, so that a part of the heating part 22 can be located above the set highest liquid level, thus being beneficial to reducing the risk of water leakage at the installation port 13.

[0044] Of course, the shape and size of the heating part 22 are not limited to the above solutions and can be adjusted as needed. The heating part 22 can be a cylindrical structure. The diameter of the heating part 22 is denoted as A1, and the sizes of A1 and B1 are not restricted and can be reasonably set as required.

[0045] In one embodiment, as Figures 2 to 6 shown, the number of the mounting openings 13 is four, and the four mounting openings 13 are arranged in an array. Correspondingly, the number of the heaters 2 is four, and the four heaters 2 correspond to the four mounting openings 13 one by one.

[0046] In some other exemplary embodiments, as Figures 8 to 12 shown, the upper part of the heating water tank 1 includes an inclined second mounting surface 12, and the mounting openings 13 are arranged on the second mounting surface 12 so that the heating part 22 can be inserted into the heating water tank 1 along the inclined direction.

[0047] Compared with the solution where the heating part 22 is inserted vertically, the inclined solution in this scheme is beneficial to increasing the area of the heating part 22 inserted under the water surface, thereby being beneficial to improving the heating efficiency of the heater 2 for water.

[0048] In some embodiments, as Figure 13 shown, the distance C2 between the center of the lower end surface of the heating part 22 and the inner bottom wall of the heating water tank 1 can be within but not limited to a range greater than or equal to 10 mm, which is beneficial to avoiding the direct heating of the inner bottom wall of the heating water tank 1 by the heater 2, resulting in the deformation or softening of the heating water tank 1 and affecting the strength of the heating water tank 1.

[0049] In some embodiments, the heating part 22 is arranged as a columnar structure (such as a cylindrical structure or a prismatic structure), and the lower end surface of the heating part 22 is lower than the set highest liquid level of the heating water tank 1 to ensure that the heating part 22 can contact the water and then heat the water. A rated water level line can be set in the heating water tank 1, and the set highest liquid level is the liquid level flush with the rated water level line.

[0050] As Figure 13 shown, the length of the heating part 22 is denoted as B2, the liquid level height of the set highest liquid level of the heating water tank 1 is denoted as E2, the intersection point of the central axis of the heating part 22 and the set highest liquid level is denoted as O, the distance between O and the lower end surface of the heating part 22 is denoted as D2, and the angle between the heating part 22 and the vertical direction is denoted as θ. D2 / B2 ≤ 0.9, E2 / ≤ 0.8 × B2 × cosθ.

[0051] Such a setting is beneficial to avoiding too high a liquid level height in the heating water tank 1 or too small a distance between the liquid surface and the mounting opening 13, so that a part of the heating part 22 can be located above the set highest liquid level, thereby being beneficial to reducing the risk of water leakage at the mounting opening 13.

[0052] Of course, the shape and size of the heating part 22 are not limited to the above solutions and can be adjusted as needed. The heating part 22 can be a cylindrical structure. The diameter of the heating part 22 is denoted as A2, and the sizes of A2 and B2 are not limited and can be reasonably set as needed.

[0053] In some embodiments, the included angle θ between the heating part 22 and the vertical direction satisfies: 30° ≤ θ < 90°, such as 30°, 45°, 60°, 75°, 85°, etc.

[0054] Of course, the included angle θ between the heating part 22 and the vertical direction is not limited to the above range and can be adjusted as needed.

[0055] In one embodiment, as Figures 8 to 12 shown, the heating water tank 1 is symmetrically provided with two second mounting surfaces 12. Each second mounting surface 12 is respectively provided with two mounting openings 13, and the mounting openings 13 on the two second mounting surfaces 12 are staggeredly arranged. Correspondingly, the number of heaters 2 is four, and the four heaters 2 correspond to the four mounting openings 13 one by one.

[0056] In some exemplary embodiments, as Figures 14 to 16 shown, the heating part 22 includes a heat-conducting outer shell 221 and a heating element 222 disposed in the heat-conducting outer shell 221. The heating element 222 is electrically connected to the wiring part 21.

[0057] The heat-conducting outer shell 221 may include a heat-conducting housing (not shown in the figure) and a heat-conducting insulating layer (not shown in the figure). The heat-conducting insulating layer is located between the heat-conducting housing and the heating element 222. The heat-conducting housing may be, but is not limited to, a metal housing. The heat-conducting insulating layer can prevent electric leakage and is beneficial to improving the use safety of the humidifying device.

[0058] In some embodiments, the heating element 222 is of an integral structure. The integral structure is powered on and off together, which is beneficial to simplifying the electric control program; and it is installed together, which is beneficial to simplifying the assembly process. The heating element 222 can be a uniform heating element 222.

[0059] In some embodiments, the heating element 222 is of an integral structure, and a dense area 2213 and a vacant area 2214 are provided in the heat-conducting outer shell 221. As Figure 14 shown, the dense area 2213 is located below the vacant area 2214, and the heating element 222 is located in the dense area 2213.

[0060] Since there is no heating element 222 in the vacant area 2214, its heating capacity is relatively low, and it can only achieve the heating function by heat transfer from the dense area 2213. However, at least part of the vacant area 2214 is located above the liquid level and does not contact water, and it can only heat the air and makes a relatively small contribution to steam generation. Therefore, the setting of the vacant area 2214 is beneficial to saving electric energy.

[0061] In some examples, the length of the dense area 2213 can be greater than the length of the vacant area 2214, as Figure 14 shown, which is beneficial to improving the overall heating power of the heating element 222, and thus ensuring the steam generation efficiency.

[0062] In some embodiments, the heating element 222 is of an integral structure. A dense area 2213 and a sparse area 2215 are provided inside the heat-conducting shell 221, as Figure 15 shown. The dense area 2213 is located below the sparse area 2215. The heating element 222 includes a first heating section 2221 and a second heating section 2222, as Figure 15 shown. The first heating section 2221 is located in the dense area 2213, and the second heating section 2222 is located in the sparse area 2215. The heating power of the first heating section 2221 is greater than that of the second heating section 2222.

[0063] Since at least part of the sparse area 2215 is located above the liquid level and does not contact water, it can only heat the air, and its contribution to steam generation is relatively small. Therefore, the heating power of the second heating section 2222 in the sparse area 2215 can be smaller, which is beneficial to saving electric energy.

[0064] For example: The heating element 222 is a PTC heating element 222. The PTC ceramic chips of the first heating section 2221 can be densely arranged to increase the heating power; the PTC ceramic chips of the second heating section 2222 can be arranged more sparsely to reduce the heating power.

[0065] In some examples, as Figure 15 shown, the length of the dense area 2213 can be greater than the length of the sparse area 2215, which is beneficial to improving the overall heating power of the heating element 222, and thus ensuring the steam generation efficiency.

[0066] In some other exemplary embodiments, the heating element 222 is of a split structure. The heating element 222 includes an independent first sub-heating element 2223 and a second sub-heating element 2224, as Figure 16 shown. The wiring part 21 includes an independent first sub-wiring part and a second sub-wiring part, as Figure 16 shown. The first sub-wiring part is electrically connected to the first sub-heating element 2223, and the second sub-wiring part is electrically connected to the second sub-heating element 2224. In this way, the first sub-heating element 2223 and the second sub-heating element 2224 can be separately controlled, which is convenient for reasonably controlling the heating power of the heater 2 according to the liquid level height in the heating water tank 1, and is beneficial to reducing the power consumption on the basis of ensuring to meet the humidification requirement.

[0067] The first sub-heating element 2223 is located below the second sub-heating element 2224, and the heating power of the first sub-heating element 2223 is greater than that of the second sub-heating element 2224.

[0068] Since the upper part of the heating element 222 is above the liquid level and does not contact water, it can only heat the air and makes a relatively small contribution to steam generation. Therefore, the heating power of the second sub-heating element 2224 located on the upper side can be smaller, which is beneficial to saving electric energy.

[0069] For example: the heating element 222 is a PTC heating element 222. The PTC ceramic sheets of the first sub-heating element 2223 can be densely arranged to increase the heating power; the PTC ceramic sheets of the second sub-heating element 2224 can be arranged sparsely to reduce the heating power.

[0070] In some examples, the length of the first sub-heating element 2223 can be greater than the length of the second sub-heating element 2224, as Figure 16 shown, which is beneficial to improving the overall heating power of the heater 2 and thus ensuring the steam generation efficiency.

[0071] In some exemplary embodiments, the wiring part 21 includes an end cap 211 and a wire body 212, as Figure 3 shown, the end cap 211 seals the installation opening 13 and supports the heating part 22. The wire body 212 is connected to the heating part 22 and is arranged to connect to the power supply module. The end cap 211 can be a flange cap. The end cap 211 can be threadedly connected to the heating water tank 1.

[0072] Among them, based on the heating element 222 being an integral structure, the wire body 212 is electrically connected to the heating element 222, as Figure 14 and Figure 15 shown.

[0073] Based on the heating element 222 being a split structure, the wire body 212 includes an independent first wire body 2121 and a second wire body 2122, as Figure 16 shown, the first wire body 2121 forms a first sub-wiring part, and the second wire body 2122 forms a second sub-wiring part. The first wire body 2121 and the second wire body 2122 can be inserted into the same end cap 211.

[0074] In some exemplary embodiments, as Figure 1 shown, the humidifying device further includes a water supply module, and the water supply module is arranged to supply water to the heating water tank 1. This can realize the automatic water supply of the humidifying device, eliminating the need for users to supply water manually, improving the intelligence level of the humidifying device, and being beneficial to improving the user experience.

[0075] In some embodiments, as Figure 1As shown, the heating water tank 1 is provided with a water inlet 14. The water supply module includes a storage water tank 3, a water inlet pipeline 31, and a first water inlet valve 32. The storage water tank 3 is communicated with the water inlet 14 of the heating water tank 1 through the water inlet pipeline 31. The first water inlet valve 32 is arranged on the water inlet pipeline 31 and is configured to control the on-off of the water inlet pipeline 31.

[0076] In some embodiments, as Figure 1 shown, the humidifying device further includes: a water inlet flow path 36 and a second water inlet valve 37. The humidifying device may further include a pressure stabilizing valve 38.

[0077] The water inlet flow path 36 is arranged to communicate the storage water tank 3 with an external water source and is configured to supply water to the storage water tank 3. The water provided by the external water source can be tap water or purified water.

[0078] The second water inlet valve 37 and the pressure stabilizing valve 38 are arranged on the water inlet flow path 36. The second water inlet valve 37 is configured to control the on-off of the water inlet flow path 36. The pressure stabilizing valve 38 is configured to stabilize the water pressure of the water inlet flow path 36 and prevent the water pressure from being too large and affecting the normal operation of the water inlet flow path 36 and subsequent components.

[0079] In some embodiments, as Figure 1 shown, the humidifying device further includes: a mechanical water level control switch 34 and a high and low water level control switch 33. The high and low water level control switch 33 is configured to control the automatic opening and closing of the second water inlet valve 37 so that the water level in the storage water tank 3 can be maintained between a set minimum water level and a maximum water level. The mechanical water level control switch 34 can play the role of a water level switch in the case of the failure of the high and low water level control switch 33 to achieve double insurance.

[0080] In some embodiments, as Figure 1 shown, the humidifying device further includes: a temperature sensor 35, arranged in the storage water tank 3 and used to detect the water temperature in the storage water tank 3.

[0081] In some embodiments, as Figure 1 shown, the humidifying device further includes: a humidity sensor 6, arranged to detect the humidity of the space to be humidified.

[0082] In some embodiments, as Figure 1 shown, the humidifying device further includes: a liquid level sensor 17, arranged in the heating water tank 1 and configured to detect the liquid level height in the heating water tank 1.

[0083] In some exemplary embodiments, as Figure 1As shown, the heating water tank 1 is provided with a steam outlet 16. The humidifying device further includes: a steam pipeline 5 and a steam control valve 51. The steam pipeline 5 is connected to the steam outlet 16, and the steam outlet 16 is communicated with the space to be humidified through the steam pipeline 5. The steam control valve 51 is arranged on the steam pipeline 5 and is configured to control the on-off between the steam outlet 16 and the space to be humidified.

[0084] In this way, by controlling the on-off between the space to be humidified and the steam outlet 16 through the steam control valve 51, the humidifying device can be controlled to humidify or stop humidifying the space to be humidified, thereby realizing automatic humidification of the humidifying device, which is beneficial to improving the user experience.

[0085] In some exemplary embodiments, as Figure 1 shown, the heating water tank 1 is provided with a drain outlet 15. The humidifying device further includes: a water receiving tray 4, a drain pipeline 41 and a drain control valve 42. The water receiving tray 4 is located below the heating water tank 1, and the water receiving tray 4 is connected to the drain outlet 15 through the drain pipeline 41. The drain control valve 42 is arranged on the drain pipeline 41 and is configured to control the on-off between the drain outlet 15 and the water receiving tray 4.

[0086] In this way, by controlling the on-off between the water receiving tray 4 and the drain outlet 15 through the drain control valve 42, the heating water tank 1 can be controlled to drain water to the water receiving tray 4 or stop draining water, thereby realizing automatic drainage of the heating water tank 1 without manual drainage by the user, which is beneficial to improving the user experience.

[0087] The embodiment of the present application further provides an air treatment device (not shown in the figure), including the humidifying device in any one of the above embodiments, and thus has all the above beneficial effects, which will not be elaborated here.

[0088] The air treatment device can be a device with air treatment functions such as an air conditioner, an air purifier, a disinfection machine, etc.

[0089] When the air treatment device is an air conditioner, the air conditioner can be a split air conditioner, and the humidifying device is connected to the indoor unit of the split air conditioner. The air conditioner can also be an integrated air conditioner.

[0090] The main body of the air treatment device can be provided with a humidifying port, and the steam outlet 16 of the humidifying device is communicated with the humidifying port.

[0091] The embodiment of the present application further provides a control method, which is applied to the humidifying device in any one of the above embodiments. As Figure 17 shown, the control method includes:

[0092] Step S202: Obtain the current humidity, target humidity of the target space to be humidified and the liquid level height in the heating water tank 1;

[0093] Step S204: Control the heater 2 according to the current humidity, the target humidity and the liquid level.

[0094] The control method provided in the embodiment of the present application uses the heater 2 to heat water to generate steam to meet the humidification demand, and there is no problem of bacterial growth, and the cleanliness is high. In addition, compared with the solution in which the heater 2 is inserted upward from the bottom of the heating water tank 1 or horizontally inserted from the side of the heating water tank 1, the heater 2 of this solution is inserted downward from the top of the heating water tank 1, and the water in the heating water tank 1 is not easy to reach the installation port 13, so it is not easy to leak.

[0095] The target humidity may be obtained through external input information. For example, the user may input the target humidity through a remote controller, an APP of a mobile terminal (such as a mobile phone, a computer, an IPad, a wristband), an operation panel of a machine, etc.

[0096] Alternatively, the target humidity may also be determined by internal storage information, for example, the target humidity may be a target humidity preset at the factory, or a target humidity memorized last time set by a user.

[0097] In some exemplary embodiments, the heating body 222 of the heating unit 22 is an integral structure, such as Figure 14 and Figure 15 As shown. The heating body 222 may be a uniform whole-segment structure and fill the entire heat-conducting outer shell 221. Alternatively, the heating body 222 may be a uniform whole-segment structure but is only located in the dense area 2213 of the heat-conducting outer shell 221. Alternatively, the heating body 222 may include a first heating segment 2221 and a second heating segment 2222, wherein the first heating segment 2221 is located in the dense area 2213, and the second heating segment 2222 is located in the evacuated area 2215, and the heating power of the first heating segment 2221 is greater than the heating power of the second heating segment 2222.

[0098] like Figure 18 As shown, according to the current humidity, the target humidity and the liquid level, the heater 2 is controlled, including:

[0099] Based on the liquid level in the heating water tank 1 being within the set height range, the heater 2 is controlled to operate;

[0100] Based on the current humidity of the target humidification space reaching the target humidity, the heater 2 is controlled to be turned off.

[0101] When the liquid level in the heating water tank 1 is within the set height range, it indicates that the water in the heating water tank 1 is sufficient, and the heater 2 is running at this time, and dry burning will not occur, and the heating part 22 can be fully immersed in water, which is conducive to improving the humidification efficiency. When the current humidity of the target humidified space reaches the target humidity, it indicates that the humidification demand has been met, so the heater 2 is controlled to be turned off.

[0102] Among them, the set height range can be but is not limited to: h1 - Δh ≤ h ≤ h1 + Δh, where h is the actual liquid level height, h1 is the set liquid level height threshold, and Δh is the liquid level height floating difference. The magnitudes of h1 and Δh are not limited and can be determined as needed.

[0103] The current humidity of the target space to be humidified reaches the target humidity, including: the current humidity d of the target space to be humidified satisfies d1 - Δd ≤ d ≤ d1 + Δd, where d1 is the target humidity and Δd is the humidity floating difference. The magnitudes of d1 and Δd are not limited and can be determined as needed. For example, Δd can be but is not limited to 2%.

[0104] In some exemplary embodiments, the heating element 222 of the heating unit 22 is a split structure, such as Figure 16 as shown, the heating element 222 includes an independent first sub - heating element 2223 and a second sub - heating element 2224. The wiring part 21 includes an independent first sub - wiring part and a second sub - wiring part. The first sub - wiring part is electrically connected to the first sub - heating element 2223, and the second sub - wiring part is electrically connected to the second sub - heating element 2224. The first sub - heating element 2223 is located below the second sub - heating element 2224, and the heating power of the first sub - heating element 2223 is greater than that of the second sub - heating element 2224.

[0105] Such as Figure 19 as shown, controlling the heater 2 according to the current humidity, target humidity, and liquid level height includes:

[0106] Based on the liquid level height in the heating water tank 1 being within the set height range, controlling the first sub - heating element 2223 and the second sub - heating element 2224 to operate;

[0107] Based on the liquid level height in the heating water tank 1 not rising to within the set height range and the water supply duration reaching the first set duration, controlling the first sub - heating element 2223 to operate and the second sub - heating element 2224 to be turned off. The first set duration is greater than the duration required for the liquid level in the heating water tank 1 to increase from zero to the set maximum liquid level;

[0108] Based on the current humidity of the target space to be humidified reaching the target humidity, controlling the heater 2 to be turned off.

[0109] In other words, when the liquid level height in the heating water tank 1 is within the set height range, it indicates that the amount of water in the heating water tank 1 is sufficient. At this time, both the first sub - heating element 2223 and the second sub - heating element 2224 operate, and dry - burning will not occur, and the heating unit 22 can be fully immersed in water, which is beneficial to improving the humidification efficiency.

[0110] When the liquid level height in the heating water tank 1 does not rise to within the set height range within the first set time period and the water supply time reaches the first set time period, it indicates that the amount of water in the heating water tank 1 is limited. At this time, only the first sub-heating element 2223 is turned on to heat the water, while the second sub-heating element 2224 is turned off to reduce the heat loss for air heating and save electric energy.

[0111] When the current humidity in the target space to be humidified reaches the target humidity, it indicates that the humidification requirement has been met, so the heater 2 is controlled to turn off.

[0112] In this way, the heater 2 is equivalent to having two working modes. It can operate at high power when the liquid level height is relatively high, or operate at low power when the liquid level height is relatively low, making the heating power of the heater 2 match the liquid level height in the heating water tank 1, taking into account both the humidification requirement and the concept of green energy conservation.

[0113] Among them, the specific duration of the first set time period is not limited. For example: the liquid level height in the heating water tank 1 can be obtained every first set interval time period (or it can be judged every first set interval time period whether the liquid level height in the heating water tank 1 is within the set height range, and the acquisition frequency of the liquid level height can be higher), and the first set time period can be an integer multiple of the first set interval time period. Or, the current humidity in the target space to be humidified can be obtained every second set interval time period (or it can be judged every second set interval time period whether the current humidity in the target space to be humidified reaches the target humidity, and the acquisition frequency of the current humidity can be higher), and the first set time period can be an integer multiple of the second set interval time period. The first set interval time period and the second set interval time period can be equal or not equal.

[0114] In some embodiments, as Figure 19 shown, controlling the heater 2 according to the current humidity, the target humidity, and the liquid level height further includes:

[0115] After controlling the first sub-heating element 2223 to operate and the second sub-heating element 2224 to be turned off for the second set time period, judge whether the liquid level height in the heating water tank 1 rises to within the set height range;

[0116] Based on the liquid level height in the heating water tank 1 rising to within the set height range, return to execute the step of controlling the first sub-heating element 2223 and the second sub-heating element 2224 to operate;

[0117] Based on the liquid level height in the heating water tank 1 not rising to within the set height range, return to execute the step of controlling the first sub-heating element 2223 to operate and the second sub-heating element 2224 to be turned off.

[0118] In other words, during the low-power operation of the heater 2, the liquid level height in the heating water tank 1 also needs to be detected. When the liquid level height in the heating water tank 1 rises to the set height range, the second sub-heating element 2224 is also turned on, so that the total heating power of the heater 2 matches the liquid level height, thereby improving the humidification efficiency of the humidifying device. When the liquid level height in the heating water tank 1 does not rise to the set height range, the low-power heating state is continued.

[0119] Among them, the specific duration of the second set duration is not limited. For example: the liquid level height in the heating water tank 1 can be obtained every first set interval duration (or it can be judged every first set interval duration whether the liquid level height in the heating water tank 1 is within the set height range, and the acquisition frequency of the liquid level height can be higher), and the second set duration can be an integer multiple of the first set interval duration. Or, the current humidity of the target space to be humidified can be obtained every second set interval duration (or it can be judged every second set interval duration whether the current humidity of the target space to be humidified reaches the target humidity, and the acquisition frequency of the current humidity can be higher), and the second set duration can be an integer multiple of the second set interval duration. The first set interval duration and the second set interval duration can be equal or not equal.

[0120] In some exemplary embodiments, the humidifying device further includes a water supply module, and the water supply module is configured to supply water to the heating water tank 1.

[0121] The control method further includes:

[0122] In response to the humidification instruction, control the water supply module to start and supply water to the heating water tank 1;

[0123] Based on the fact that the liquid level height in the heating water tank 1 does not rise to the set height range within the third set duration, issue a reminder message for abnormal liquid level height.

[0124] Under normal circumstances, within the third set duration, the liquid level height of the heating water tank 1 should be able to rise to the set height range. Otherwise, it may be a failure of the water supply module, or abnormal water pressure, or leakage of the heating water tank 1, or other abnormal situations. Therefore, issuing a reminder message for abnormal liquid level height can remind the user to check in time to avoid losses to the user as much as possible. The third set duration can be equal to the first set duration.

[0125] As for the form of issuing the reminder message, it is not limited. For example, sound signals, light signals, voice signals, picture signals, etc. are all acceptable. Controlling the water supply module to start includes: controlling the first water inlet valve 32 to open.

[0126] In some exemplary embodiments, the control method further includes:

[0127] Based on the liquid level height in the heating water tank 1 rising to the upper limit value of the set height range, control the water supply module to close;

[0128] Based on the liquid level height in the heating water tank 1 dropping to the lower limit value of the set height range, control the water supply module to open.

[0129] In other words, during the operation of the humidifying device, the opening and closing of the water supply module can be automatically controlled according to the liquid level height in the heating water tank 1, so that the liquid level height in the heating water tank 1 can be maintained within the set height range.

[0130] In other embodiments, the first water inlet valve 32 can also be set as a flow switch, and the opening degree of the flow switch can be dynamically adjusted according to the change in the water volume in the humidifying water tank, so that the liquid level height in the heating water tank 1 can be maintained within the set height range.

[0131] In some exemplary embodiments, the control method further includes: in response to a humidifying instruction, control the steam pipeline 5 to conduct, so that the steam pipeline 5 outputs steam to the target space to be humidified.

[0132] In some exemplary embodiments, the control method further includes: based on the heater 2 being turned off, control the heating water tank 1 to drain water. This can avoid the long-term accumulation of water in the heating water tank 1 and the growth of bacteria.
