[0018] The preferred embodiments of the present application will be described below with reference to the accompanying drawings.

[0019] Example 1

[0020] Embodiment 1 of the present application provides a control method for a humidity control system. The humidity control system includes a humidification module, a water inlet module, and a water level detection module. The humidification module humidifies the introduced air; the water inlet module supplies water to the humidification module; and the water level detection module includes a plurality of detection units, each of which detects different water levels of the humidification module.

[0021] Figure 1 Schematic diagram of a control method of a humidity control system according to an embodiment of the present application. Figure 1 As shown, the method includes:

[0022] Step 101: When a first water level detection unit detects a first water level, if a second water level detection unit below the first water level detects a second water level, it is indicated that the second water level detection unit is abnormal.

[0023] According to the above embodiment, the water level detection module includes a plurality of detection units for detecting different water levels of the humidification module. When the first water level detection unit detects the first water level, if the second water level detection unit below the first water level does not detect the second water level, it indicates that the second water level detection unit is abnormal, thereby improving the convenience of detection. In addition, when an abnormality is detected in the water level detection module, the corresponding abnormal information is prompted, which can facilitate users to find faults in time, help to accurately control the water level, prevent water waste or prevent excessive humidification from causing user discomfort, and improve user experience.

[0024] For example, according to the above embodiment, when the water circuit of the humidity control system adopts a hidden design, it is not necessary to open the housing of the humidity control system to detect the water level detection module. Since the water level detection module is provided with a plurality of detection units for detecting different water levels, there is a corresponding logical relationship between the detection results of the plurality of detection units. Therefore, it is possible to determine whether the plurality of detection units are abnormal based on the detection results of the plurality of detection units, and the water inlet module can be easily detected.

[0025] The control method of the embodiment of the present application can be applied to various humidity control systems. Figure 2 Schematic diagram of the structure of the humidity control system of the embodiment of the present application. Figure 2 In the figure, the pipes with arrows connecting modules or devices are air pipes; the solid lines between modules or devices represent refrigerant pipes; the dotted lines between modules or devices represent communication connections, which can be wired connections or wireless connections; and the dot-dash lines between modules or devices represent water routes.

[0026] like Figure 2 As shown, the humidity control system 200 includes: a water inlet module 210, a humidification module 220 and a water level detection module (not shown). The water inlet module 210 supplies water to the humidification module 220; the humidification module 220 humidifies the introduced air. The water level detection module includes a plurality of detection units, each detection unit respectively detects different water levels of the humidification module 220.

[0027] In some embodiments, when the water inlet module 210 is turned on, the water inlet module 210 supplies water to the humidification module 220 ; when the water inlet module 210 is turned off, the water inlet module 210 does not supply water to the humidification module 220 .

[0028] Figure 3 2 is a schematic diagram of a partial structure of a humidity control system 200 according to an embodiment of the present application. Figure 3 As shown, the water inlet module 210 of the humidity control system 200 may include a first valve 2102. When the first valve 2102 is opened, the water inlet module 210 is opened; when the first valve 2102 is closed, the water inlet module 210 is closed. The present application is not limited thereto, and the water inlet module 210 may also include components such as a waterway connected to the first valve 2102, or the water inlet module 210 may also be other structures.

[0029] In some embodiments, the first valve 2102 may include one or more sub-valves. In the case where the first valve 2102 includes multiple sub-valves, the multiple sub-valves may be connected in various ways, for example, in parallel, in series, or in a combination of parallel and series. Figure 3 As shown, the first valve 2102 may include a first sub-valve 2102-1 and a second sub-valve 2102-2 arranged in series.

[0030] In some embodiments, when the first valve 2102 includes two or more sub-valves arranged in series, closing the first valve 2102 includes closing at least one sub-valve, and opening the first valve 2102 includes opening all sub-valves. Figure 3 As shown, closing the first valve 2102 may include closing at least one of the first sub-valve 2102-1 and the second sub-valve 2102-2, and opening the first valve 2102 may include opening both the first sub-valve 2102-1 and the second sub-valve 2102-2.

[0031] In some embodiments, the first valve 2102 may include various valves capable of controlling opening and closing or the size of the opening, such as a solenoid valve.

[0032] In some embodiments, Figure 3 As shown, the humidification module 220 may include a humidification unit 2201 and a water storage unit 2205. The water storage unit 2205 may be connected to the water inlet module 210 to supply water to the humidification unit 2201. Figure 3 As shown, the water inlet module 210 can be arranged between the water inlet 240 of the humidity regulating system 200 and the water inlet of the water storage unit 2205, and by setting the water inlet module 210 to different working states, it is controlled whether water is fed from the water inlet 240 to the water storage unit 2205. For example, when the first valve 2102 is opened, water is fed from the water inlet 240 of the humidity regulating system 200 to the water storage unit 2205, and when the first valve 2102 is closed, water is not fed from the water inlet 240 of the humidity regulating system 200 to the water storage unit 2205. The present application is not limited thereto, and the humidification module 220 may also not include the water storage unit 2205, for example, the water inlet module 210 may also be connected to the humidification unit 2201, etc.

[0033] In some embodiments, Figure 3As shown, in the humidification module 220, the humidification unit 2201 can perform humidification based on a wet film. The water in the water storage unit 2205 flows into the wet film, and the wet film absorbs water to form a uniform water film. When the dry air passes through the wet film, the water molecules fully absorb the heat in the air and vaporize and evaporate, thereby increasing the humidity of the air and forming humid air. The present application is not limited to this, and the humidification unit 2201 can also be based on other humidification principles. For example, the humidification module 220 performs humidification based on waterless humidification, and the moisture in the air is adsorbed by the hygroscopic material. The air absorbs moisture through the hygroscopic sector of the humidification wheel, and then the humidification wheel passes through the dehumidification zone for dehumidification, and the hot and humid air is sent into the room through the fan. For another example, the humidification module 220 performs humidification based on spray humidification, and the spray humidification directly inputs water vapor into the room through the action of the spray head. For another example, the humidification module 220 performs humidification based on steam humidification. Steam humidification is achieved by separating the steam and water of saturated steam, and then the dry steam enters the nozzle through a regulating valve and is sprayed out from the spray hole with a sound-absorbing metal mesh, thereby humidifying the air.

[0034] In some embodiments, Figure 3 As shown, the humidifying device 220 may further include a temperature regulating unit 2202. The temperature regulating unit 2202 is located at the upstream side of the humidifying unit 2201 and is used to regulate the temperature of the introduced air, such as heating it. The heated air is transported to the humidifying unit 2201, which can improve the humidification efficiency of the humidifying unit 2201.

[0035] For the temperature adjustment unit 2202 based on different principles, the way of adjusting the temperature may be different. Figure 3 As shown, the temperature control unit 2202 performs temperature control based on the heat exchange principle, and its temperature control capability can be adjusted by adjusting the opening of the valve 2203 (refrigerant valve) of the refrigerant pipeline in the heat exchange module. For another example, the temperature control unit 2202 performs temperature control based on the electric auxiliary heating principle, and its temperature control capability can be adjusted by adjusting the output power of the electric auxiliary heating element.

[0036] When the temperature adjustment unit 2202 adjusts the temperature based on the heat exchange principle, the humidification module 220 may further include a filter unit 2204. Before the refrigerant flows into the temperature adjustment unit 2202 via the refrigerant valve 2203, it first passes through the filter unit 2204 to filter out impurities in the refrigerant to avoid blocking the refrigerant pipeline and improve the heat exchange efficiency.

[0037] In some embodiments, Figure 3 As shown, the humidification module 220 may further include a second valve 2206. The second valve 2206 may be disposed at the drain outlet side of the water storage unit 2205.

[0038] The drain outlet of the water storage unit 2205 can be connected to the water inlet of the humidification module 220 (i.e., the water inlet of the humidification unit 2201). The second valve 2206 can be arranged between the drain outlet of the water storage unit 2205 and the water inlet of the humidification unit 2201 to control the on-off of the water path between the drain outlet of the water storage unit 2205 and the water inlet of the humidification unit 2201. For example, the second valve 2206 can be set to a state where water is supplied from the water storage unit 2205 to the humidification module 220, so that the water storage unit 2205 is connected to the humidification unit 2201 and water is supplied to the humidification unit 2201; or, the second valve 2206 can be set to a state where the water outlet of the water storage unit 2205 is closed, so that the water storage unit 2205 and the humidification unit 2201 are cut off and water supply to the humidification unit 2201 is stopped.

[0039] The drain outlet of the water storage unit 2205 may also be connected to the drain outlet 250 of the humidity control system 200. The second valve 2206 may be disposed between the drain outlet of the water storage unit 2205 and the drain outlet 250 of the humidity control system 200 to control the on-off of the water path between the drain outlet of the water storage unit 2205 and the drain outlet 250 of the humidity control system 200. For example, the second valve 2206 may be set to a state where water is discharged from the water storage unit 2205 to the drain outlet 250; or the second valve 2206 may be set to a state where the water outlet of the water storage unit 2205 is closed, and the water storage unit 2205 does not discharge water.

[0040] In some embodiments, the second valve 2206 may also be disposed on the drain side of the humidification module 220. For example, the second valve 2206 may be disposed between the drain of the humidification module 220 and the drain 250 of the humidity control system 200. When the second valve 2206 is opened, the humidification module 220 drains water to the drain 250, and when the second valve 2206 is closed, the humidification module 220 does not drain water.

[0041] In some embodiments, the second valve 2206 may also be disposed on the drainage side of the water storage unit 2205 and the humidification module 220. Thus, drainage of the water storage unit 2205 and / or water supply to the humidification module 220 and drainage of the humidification module 220 can be controlled.

[0042] In some embodiments, the second valve 2206 may be any valve capable of controlling opening, closing, or opening size. For example, the second valve 2206 may be a three-way valve. Figure 3 As shown, when the second valve 2206 is a three-way valve, its first port a can be connected to the drain outlet of the water storage unit 2205, the second port b can be connected to the water inlet of the humidification unit 2201 of the humidification module 220, and the third port c can be connected to the drain outlet 250 of the humidity adjustment system 200.

[0043] When the first port a is connected to the second port b, water is supplied from the water storage unit 2205 to the humidifying unit 2201. When the first port a is connected to the third port c, the water storage unit 2205 discharges water to the drain port 250. When the second port b is connected to the third port c, the humidifying unit 2201 discharges water to the drain port 250. Thus, the water path between the water storage unit 2205 and the humidifying module 220, the water path between the water storage unit 2205 and the drain port 250, and the water path between the humidifying module 220 and the drain port 250 can be controlled by one valve, which helps to reduce the components of the humidity control system 200 and simplify the internal structure of the humidity control system 200.

[0044] In some embodiments, Figure 3 As shown, in the humidity adjustment system 200, the water level detection module 260 is used to obtain the water level information of the humidification module 220. The water level information of the humidification module 220 may include the water level information in the water storage unit 2205 or the water level information in the humidification unit 2201, etc.

[0045] In some embodiments, the water level detection module 260 may be a module capable of detecting water level in various forms. For example, the water level detection module 260 may include multiple detection units for detecting multiple water levels of the humidification module 220, and the detection unit may be a sensor, such as a sensor in the form of a float switch.

[0046] Figure 4 Schematic diagram of the structure of the water storage unit, water level detection module, second valve and humidification unit in the embodiment of the present application. Figure 4 , the water level detection module 260 is described exemplarily by taking the water level detection module 260 detecting the water level in the water storage module 2205 of the humidification module 220 as an example. It is understandable that the water level detection module 260 can detect the water level of other components of the humidification module 220 in the same or similar manner.

[0047] like Figure 4 As shown, the water storage unit 2205 is connected to the humidifying unit 2201 , the second valve 2206 controls the water path between the water storage unit 2205 and the humidifying unit 2201 , and the water level detection module 260 is disposed in the water storage unit 2205 for detecting the water level in the water storage unit 2205 .

[0048] like Figure 4As shown, the water level detection module 260 may include three detection units, namely a first detection unit 261, a second detection unit 262 and a third detection unit 263. The first detection unit 261, the second detection unit 262 and the third detection unit 263 are used to detect the high water level, the middle water level and the low water level of the water storage unit 2205, respectively, wherein the low water level is located below the middle water level, and the middle water level is located below the high water level.

[0049] When the water level in the water storage unit 2205 reaches a low water level, the third detection unit 263 switches the output state; when the water level in the water storage unit 2205 reaches a medium water level, the second detection unit 262 switches the output state; when the water level in the water storage unit 2205 reaches a high water level, the first detection unit 261 switches the output state.

[0050] In some embodiments, the first detection unit 261, the second detection unit 262, and the third detection unit 263 may be implemented by two sensors (a first sensor A and a second sensor B). The first sensor A and the second sensor B are two independent sensors.

[0051] For example, Figure 4 As shown, the first detection unit 261 and the second detection unit 262 are the first sensor A, and the high water level detected by the first detection unit 261 and the middle water level detected by the second detection unit 262 correspond to the two sensing positions of the first sensor A. The third detection unit 263 is the second sensor B, and the low water level detected by the third detection unit 263 corresponds to the sensing position of the second sensor B.

[0052] The first sensor includes a first switch component A1, a first float A2, and a second switch component A3, wherein the first switch component A1 is located near the high water level, and the second switch component A3 is located near the middle water level. When the water level is lower than the position where the second switch component A3 is located (for example, lower than the middle water level), the first float A2 is located near the second switch component A3, the output state of the second switch component A3 is the first state, for example, OFF, and the output state of the first switch component A1 is the second state, for example, ON; after the water level rises to the position where the second switch component A3 is located, the first float A2 separates from the second switch component A3 as the water level rises, and the output state of the second switch component A3 switches to a state different from the first state, for example, ON; when the first float A2 rises with the water level to the position where the first switch component A1 is located (for example, reaches the high water level), the output state of the first switch component A1 switches to a state different from the second state, for example, OFF.

[0053] The second sensor B includes a third switch component B1 and a second float B2. When the water level is lower than the position of the third switch component B1 (for example, lower than the low water level), the output state of the third switch component B1 is the third state, for example, OFF; after the water level rises to the position of the third switch component B1, the second float B2 separates from the third switch component B1 as the water level rises, and the output state of the third switch component B1 is switched to a state different from the third state, for example, ON.

[0054] The output states of the first switch assembly A1 , the second switch assembly A3 and the third switch assembly B1 are used as the output states of the first detection unit 261 , the second detection unit 262 and the third detection unit 263 . Table 1 shows the corresponding relationship between each output state and the water level.

[0055] Table 1 Correspondence between the output states of the first detection unit 261, the second detection unit 262 and the third detection unit 263 and the water level:

[0056] The first detection unit 261 Second detection unit 262 The third detection unit 263 Water Level OFF ON ON High Water Level ON ON ON Medium water level ON OFF ON Low Water Level ON OFF OFF No water level detected

[0057] It should be noted that the present application is not limited thereto, and a combination of other output states of the first detection unit 261 , the second detection unit 262 , and the third detection unit 263 may also be used to represent different water levels.

[0058] In some embodiments, the first detection unit 261, the second detection unit 262, and the third detection unit 263 can be implemented by three independent sensors, and the water levels detected by the first detection unit 261, the second detection unit 262, and the third detection unit 263 correspond to the sensing positions of the three sensors respectively. For example, three second sensors B can be set, and the sensing position of each second sensor B corresponds to a high water level, a middle water level, and a low water level respectively. The present application is not limited thereto, and the water level detection module 260 can also be a sensor of other structures; or, the water level detection module 260 can also include two or more detection units to detect two or more different water levels.

[0059] In some embodiments, Figure 2 As shown, the humidity adjustment system 200 further includes: an air supply module 230, which is disposed inside the humidification module or outside the humidification device to introduce air into the humidification module.

[0060] In some embodiments, in the case where the air supply module 230 is disposed outside the humidification module, the air supply module 230 is disposed on the upstream side of the humidification module, or the air supply module 230 is disposed on the downstream side of the humidification module.

[0061] For example, the air supply module 230 may be arranged in a fresh air processing device, a full heat exchange device, or a ventilation device, wherein the full heat exchange device may or may not have an internal circulation function, and the ventilation device may or may not have an internal circulation function.

[0062] In some embodiments, when the air supply module 230 is disposed inside the humidification module, the air supply module 230 may be a fan, etc. In the embodiments of the present application, "downstream side" refers to the downstream side in the air flow path, and "upstream side" refers to the upstream side in the air flow path.

[0063] In some embodiments, the humidity control system 200 of the present application may control multiple indoor spaces, and the humidifier 220 supplies air to the multiple indoor spaces through multiple air pipes 270. Figure 2 In the figure, two indoor spaces (space 1 and space 2) are taken as an example for explanation, however, the embodiment of the present application is not limited to two spaces, and may also be more spaces and more air ducts are set to supply air.

[0064] In some embodiments, the indoor space that is the object of the humidity control system may include multiple areas, and the humidifier 220 supplies air to the multiple areas of the indoor space through multiple air ducts 270 .

[0065] In some embodiments, the air duct 270 is an air inlet duct, and each air duct 270 corresponds to a different indoor space, or corresponds to a different area of ​​the indoor space.

[0066] In some embodiments, Figure 2 As shown, an air duct 271 serving as a return air duct may also be provided to centrally return air to each indoor space or each area and discharge the air to the outdoors.

[0067] In the embodiment of the present application, the humidity control system 200 may be a commercial humidity control system or a household humidity control system.

[0068] In some embodiments, the humidity control system 200 may include at least one group of outdoor units 281 and at least one indoor unit 282 connected to each group of outdoor units. That is, in the humidity control system 200, one or more groups of outdoor units 281 may be included, each group of outdoor units includes at least one outdoor unit; for a group of outdoor units, the group of outdoor units is connected to at least one indoor unit 282.

[0069] For example, the humidity adjustment system 200 includes an outdoor unit and an indoor unit connected to the outdoor unit.

[0070] For example, the humidity adjustment system 200 includes an outdoor unit and at least two indoor units connected to the outdoor unit.

[0071] For example, the humidity adjustment system 200 includes at least two outdoor units and at least two indoor units connected to the at least two outdoor units.

[0072] For example, a group of outdoor units and at least one indoor unit connected to the group of outdoor units constitute a refrigerant system, or multiple groups of outdoor units and at least one indoor unit respectively connected to the multiple groups of outdoor units constitute multiple refrigerant systems. Thus, the humidity control system 200 may include one refrigerant system or multiple refrigerant systems.

[0073] In some embodiments, the outdoor unit and the indoor unit may be air conditioning equipment of various models, types, forms, and capacities. For example, the indoor unit may be in the form of four-sided air outlet, two-sided air outlet, duct unit, ground air outlet, or skirting air outlet; the outdoor unit may be in the form of single fan upper air outlet, double fan upper air outlet, single fan front air outlet, or double fan front air outlet.

[0074] In some embodiments, Figure 2 As shown, the humidity adjustment system 200 may further include a control module 290. The control module 290 may control the working state of each module or device in the humidity adjustment system 200.

[0075] In some embodiments, the control module 290 may include a controller, for example, the controller may be a centralized controller, a wired controller, a remote controller, an intelligent controller, etc. The controller may generate control instructions for each module or device in the humidity control system 200 according to information input by the user.

[0076] In some embodiments, the control module 290 may further include a gateway device that collects data from various modules or devices and generates control instructions for various modules or devices in the humidity control system 200 based on the data.

[0077] For example, the control module 290 can generate a control instruction for the humidity control system 200 to execute the control method of the embodiment of the present application according to the instruction input by the user or the collected data. The control module 290 can send the instruction to the air supply module 230, and the air supply module 230 sends the instruction to the water inlet module 210 and / or the humidification module 220 through the communication line; or the control module 290 can also send the instruction to the air supply module 230, the water inlet module 210 and the humidification module 220.

[0078] In some embodiments, the control method of the humidity control system 200 can be executed in the normal operation mode of the humidity control system 200. For example, in the normal operation mode of adjusting the humidity of the indoor space, it can be determined whether the detection unit of the water level detection module 260 is abnormal according to the detection result of the water level detection module 260, and in the case of an abnormality, the corresponding abnormal information is prompted. As a result, the fault of the water level detection module 260 can be discovered without interrupting the normal operation mode of the humidity control system 200, thereby further improving the user experience. The present application is not limited to this, and the control method of the humidity control system can also be executed in other operation modes of the humidity control system 200, such as the trial operation mode. In the trial operation mode, the humidity control system 200 may not adjust the humidity of the indoor space (for example, not perform humidification operation), and only detect the components of the humidity control system 200.

[0079] In some embodiments, in step 101 of the control method, when the first water level detection unit detects the first water level, if the second water level detection unit below the first water level does not detect the second water level, it indicates that the second water level detection unit is abnormal.

[0080] In other words, it can be determined whether the detection unit of the lower second water level has an abnormality based on the detection result of the higher first water level.

[0081] In some embodiments, Figure 1 As shown, the control method may also include:

[0082] Step 102, when the water inlet module is turned on and the first water level detection unit detects the first water level, if the third water level detection unit above the first water level does not detect the third water level within a preset time, it is prompted that the third water level detection unit is abnormal.

[0083] In other words, it can be determined whether the detection unit of the higher third water level has an abnormality according to the detection result of the lower first water level and the working state of the water inlet module.

[0084] In some embodiments, the first water level may include a water level adjacent to the third water level. Since the time from the first water level to the adjacent water level is shorter than the time to the non-adjacent water level, the detection time can be shortened, the detection efficiency can be improved, and the user experience can be further improved.

[0085] For example, in the case of detecting three water levels, low, medium and high, when the initial water level is a low water level, the third water level may be a medium water level; when the initial water level is a medium water level, the third water level may be a high water level. The present application is not limited thereto, and the third water level may also be a water level that is not adjacent to the initial water level. Thus, the reliability of the detection result can be further improved. For example, when the initial water level is a low water level, the third water level may be a high water level.

[0086] In some embodiments, the third water level may include a highest water level that the water level detection module 260 can detect.

[0087] In other words, for the highest water level among the multiple water levels that the water level detection module 260 can detect, it can be determined whether there is an abnormality in the detection unit of the highest water level of the detection module 260 based on the detection results of other water levels except the highest water level among the multiple water levels that the water level detection module 260 can detect, and the working status of the water inlet module 210.

[0088] For example, according to the detection result of the second highest water level among the multiple water levels detectable by the water level detection module 260 and the working state of the water inlet module 210, it is determined whether the detection unit of the highest water level of the detection module 260 has an abnormality.

[0089] In some embodiments, for other water levels except the highest water level among the multiple water levels that the water level detection module 260 can detect, it can be determined whether the detection unit of the other water levels has an abnormality based on the detection result of the water level higher than the other water levels. In this way, it is possible to determine whether the detection unit has an abnormality in a simple manner. The present application is not limited to this. For these other water levels, it is also possible to determine whether the detection unit of the other water levels has an abnormality based on the detection result of the water level lower than the other water levels and the working state of the water inlet module; or, abnormality detection is performed according to the above two methods, thereby improving the reliability of the detection results.

[0090] In some embodiments, the specific type of abnormality of each detection unit can be determined based on the corresponding relationship between the output state of each detection unit and the water level of the water level detection module 260. For example, in the case where the detection unit is a sensor in the form of a float switch, it can be determined whether the float of the detection unit has fallen off, whether the detection unit has a circuit break or a short circuit.

[0091] For example, Figure 4As shown in Table 1, the detection unit is a sensor in the form of a float switch. When the float is separated from the switch assembly (for example, the distance between the two is greater than the preset distance), the output state is ON; when the float is near the switch assembly (for example, the distance between the two is less than the preset distance), the output state is OFF. When the output state of the detection unit should be ON, but the output is OFF, it can be determined that a short circuit has occurred between the float and the switch assembly of the detection unit; when the output state of the detection unit should be OFF, but the output is ON, it can be determined that the float of the detection unit has fallen off or a circuit break has occurred between the float and the switch assembly.

[0092] In some embodiments, for different abnormalities of each detection unit of the water level detection module 260, abnormal information corresponding to the abnormality can be prompted so that the user can accurately understand the type of abnormality that has occurred.

[0093] Hereinafter, taking the example that the water level detection module 260 includes a first detection unit, a second detection unit, and a third detection unit, and the first detection unit, the second detection unit, and the third detection unit detect high water level, middle water level, and low water level respectively, a specific method for determining whether there is an abnormality in the first detection unit, the second detection unit, and the third detection unit is exemplarily described. Among them, the high water level can be the full water level of the water storage unit 2205, the middle water level can be the water supply level of the water storage unit 2205, and the low water level can be the anti-condensation water level of the water storage unit 2205. It can be understood that the following description is also applicable to each detection unit in the case where the water level detection module 260 includes 2 detection units or 4 or more detection units.

[0094] Method for determining whether the first detection unit is abnormal

[0095] In some embodiments, for the first detection unit that detects high water level, when the water inlet module 210 is turned on and the second detection unit detects a medium water level, if the first detection unit does not detect a high water level within a first preset time, the first detection unit is abnormal.

[0096] For example, when the first sub-valve 2102-1 (solenoid valve 1) and the second sub-valve 2102-2 (solenoid valve 2) in the water inlet module 210 are opened, the output states of the first detection unit 261 and the second detection unit 262 are ON, ON, that is, the water level is detected. After 15 minutes (the first preset time), the output states of the first detection unit 261 and the second detection unit 262 are still ON, ON, that is, the full water level is still not detected. Then, there is an abnormality in the first detection unit 261.

[0097] Since the output state of the first detection unit 261 should be switched to OFF but remains ON, it can be determined that the float of the first detection unit 261 has fallen off or a circuit break has occurred between the float and the switch assembly. Accordingly, abnormal information corresponding to the abnormality can be prompted, for example, an A3-12 type alarm information.

[0098] In some embodiments, when the above-mentioned abnormality is detected, the water inlet module 210 can be closed, for example, the first sub-valve 2102-1 (solenoid valve 1) and the second sub-valve 2102-2 (solenoid valve 2) can be closed to prevent overflow and water waste, or to prevent excessive humidification and affect the user experience.

[0099] In some embodiments, for the first detection unit that detects a high water level, if the first detection unit continues to detect a high water level within a second preset time, the first detection unit is abnormal.

[0100] For example, if the output state of the first detection unit 261 remains OFF for 60 minutes (the second preset time), then the first detection unit 261 is abnormal. This is because in the normal operation mode of the humidity adjustment system 200, the water level in the water storage unit 2205 will not remain full for a long time (for example, 60 minutes). If it is detected that the first detection unit 261 always outputs the OFF state, it can be determined that the first detection unit 261 is abnormal.

[0101] Since the output state of the first detection unit 261 should be switched to ON but remains OFF, it can be determined that a short circuit abnormality occurs between the float and the switch assembly of the first detection unit 261. Accordingly, abnormal information corresponding to the abnormality can be prompted, for example, an A3-13 type alarm information.

[0102] Method for determining whether the second detection unit is abnormal

[0103] In some embodiments, for the second detection unit that detects the middle water level, when the third detection unit does not detect the low water level and the first detection unit does not detect the high water level, the second detection unit detects the middle water level and the second detection unit is abnormal.

[0104] For example, if the output state of the first detection unit 261 is ON, the output state of the second detection unit 262 is ON, and the output state of the third detection unit 263 is OFF, then the second detection unit 262 is abnormal.

[0105] Since the output state of the second detection unit 262 should be switched to OFF but remains ON, it can be determined that the float of the second detection unit 262 has fallen off or a circuit break has occurred between the float and the switch assembly. Accordingly, abnormal information corresponding to the abnormality can be prompted, for example, an A3-14 type alarm information.

[0106] In some embodiments, for the second detection unit that detects the middle water level, when the first detection unit detects the high water level, the second detection unit does not detect the middle water level, and the second detection unit is abnormal.

[0107] For example, if the output state of the first detection unit 261 is OFF and the output state of the second detection unit 262 is OFF, then the second detection unit 262 is abnormal.

[0108] Since the output state of the second detection unit 262 should be switched to ON but remains OFF, it can be determined that a short circuit abnormality occurs between the float and the switch assembly of the second detection unit 262. Accordingly, abnormal information corresponding to the abnormality can be prompted, for example, an A3-15 type alarm information.

[0109] Method for determining whether the third detection unit is abnormal

[0110] In some embodiments, for the third detection unit for detecting low water level, when the humidification module 210 stops humidification remote control, the third detection unit continues to detect the low water level within a third preset time, and the third detection unit is abnormal.

[0111] For example, when the humidification module 210 does not perform humidification operation (i.e., humidification operation = OFF), the water storage unit 2205 should remain dry, i.e., below the low water level. If the output state of the third detection unit 263 is ON, it means that the low water level is detected, and the third detection unit 263 is abnormal.

[0112] Since the output state of the third detection unit 263 should be switched to OFF but remains ON, it can be determined that the float of the third detection unit 263 has fallen off or a circuit break has occurred between the float and the switch assembly. Accordingly, abnormal information corresponding to the abnormality can be prompted, for example, an A3-16 type alarm information.

[0113] In some embodiments, for the third detection unit for detecting low water level, when the first detection unit detects high water level and / or the second detection unit detects medium water level, the third detection unit does not detect low water level and the third detection unit is abnormal.

[0114] For example, if the output state of the first detection unit 261 is OFF and / or the output state of the second detection unit 262 is ON, and the output state of the third detection unit 263 is OFF, then the third detection unit 263 is abnormal.

[0115] Since the output state of the third detection unit 263 should be switched to ON but remains OFF, it can be determined that a short circuit abnormality occurs between the float and the switch assembly of the third detection unit 263. Accordingly, abnormal information corresponding to the abnormality can be prompted, for example, an A3-17 type alarm information.

[0116] In the above embodiment, there is no restriction on the state of the second valve 2206. For example, the second valve 2206 may be in a state of closing the drain port of the water storage unit 2205, or in a state of supplying water from the water storage unit 2205 to the humidifying unit 2201, wherein the speed of water inflow from the water inlet 240 to the water storage unit 2205 is greater than the speed of water supply from the water storage unit 2205 to the humidifying unit 2201, or in a state of discharging water from the water storage unit 2205 to the drain port 250, wherein the speed of water inflow from the water inlet 240 to the water storage unit 2205 is greater than the speed of water discharging from the water storage unit 2205 to the drain port 250.

[0117] In some embodiments, when the humidity adjustment system 200 includes the air supply module 230, Figure 1 As shown, the control method may also include:

[0118] Step 103, when it is determined that the water level detection module 260 has an abnormality, the air supply module 230 maintains the air supply mode before the abnormality is determined.

[0119] For example, in the case of abnormalities such as float detachment, short circuit or open circuit in the water level detection module 260, the air supply of the air supply module 230 is not affected. Thus, the influence of the failure of the water level detection module 260 on the air supply module 230 can be avoided, the air supply volume can be guaranteed, and the user experience can be further improved.

[0120] The present application is not limited thereto, and when it is determined that the water level detection module 260 is abnormal, the air supply module 230 may also stop introducing air into the humidification module.

[0121] In some embodiments, when the humidification module 220 includes a temperature adjustment unit 2202 for adjusting the temperature of the introduced air, Figure 1 As shown, the control method may also include:

[0122] Step 104 , when it is determined that the water level detection module 260 is abnormal, the temperature adjustment unit 2202 stops adjusting the temperature of the introduced air.

[0123] For example, when the water level detection module 260 has an abnormality such as float shedding, short circuit or open circuit, the refrigerant valve 2203 of the humidification module 220 is closed. Thus, large fluctuations in air temperature can be avoided, which helps to further improve user experience.

[0124] It is worth noting that the above Figure 1 The embodiments of the present application are only schematically described, but the present application is not limited thereto. For example, the execution order of the various operations can be appropriately adjusted, and other operations can be added or some operations can be reduced. In addition, the objects of the above operations can be adjusted. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the above appended Figure 1 Records of. Figure 1 Optional steps are indicated by dashed boxes.

[0125] According to the above embodiment, the water level detection module includes a plurality of detection units for detecting different water levels of the humidification module. When the first water level detection unit detects the first water level, if the second water level detection unit below the first water level does not detect the second water level, it indicates that the second water level detection unit is abnormal, thereby improving the convenience of detection. In addition, when an abnormality is detected in the water level detection module, the corresponding abnormal information is prompted, which can facilitate users to find faults in time, help to accurately control the water level, prevent water waste or prevent excessive humidification from causing user discomfort, and improve user experience.
