[0045] It should be understood that the specific embodiments described herein merely exemplify the application and do not limit the application.

[0046] Referring to Fig. 1 , Fig. 1 The structure diagram of the humidifying mechanism air leakage detection device related to the hardware running environment of the embodiment of the present application is shown.

The communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 can include a display screen (Display), and the optional user interface 1003 can also include a standard wired interface, a wireless interface. The wired interface of the user interface 1003 can be a USB interface in the present application. The network interface 1004 can optionally include a standard wired interface, a wireless interface (such as a wireless fidelity (Wireless-Fidelity, Wi-Fi) interface). The memory 1005 can be a high-speed random access memory (RAM) memory, and can also be a stable memory (Non-volatile Memory, NVM), such as a magnetic disk memory. The memory 1005 can also be an independent storage device from the aforementioned processor 1001.

[0048] Those skilled in the art can understand that Fig. 1 the structure shown in the foregoing embodiments does not constitute a limitation on the humidifying mechanism air leakage detection device, and can include more or fewer components than the illustrated components, or combine certain components, or different component arrangements.

[0049] As Fig. 1 shown, the memory 1005, which is a computer storage medium, can include an operating system, a network communication module, a user interface module, and a humidifying mechanism air leakage detection program.

[0050] In Fig. 1The network interface 1004 is mainly used for connecting a background server and communicating data with the background server; the user interface 1003 is mainly used for connecting a user device; the humidification mechanism air leakage detection equipment calls the humidification mechanism air leakage detection program stored in the memory 1005 through the processor 1001, and executes the humidification mechanism air leakage detection method provided in the embodiment of the application.

[0051] Based on the above hardware structure, embodiments of the humidification mechanism air leakage detection method are provided.

[0052] Before the control method is described, the humidification mechanism in the embodiment is described first. Referring to Fig. 2 , Fig. 2 The structure schematic diagram of the humidification mechanism in an embodiment of the application is shown.

[0053] In the first embodiment, the humidification mechanism has a moisture absorption air duct 10, a humidification air duct 20 and a water storage rotating disc 40, the water storage rotating disc 40 is partially located in the moisture absorption air duct 10 and partially located in the humidification air duct 20, and the water storage rotating disc 40 is rotatably arranged in the moisture absorption air duct 10 and the humidification air duct 20; when the water storage rotating disc 40 rotates, the water storage rotating disc 40 located in the moisture absorption air duct 10 rotates into the humidification air duct 20, and the water storage rotating disc 40 located in the humidification air duct 20 rotates into the moisture absorption air duct 10; the moisture absorption air duct 10 is provided with a moisture absorption fan 52, and the humidification air duct 20 is provided with a humidification fan 51.

[0054] The humidification mechanism in the embodiment is a waterless humidification scheme, which extracts moisture from outdoor air to deliver to indoor environment. The water storage rotating disc 40 is provided with a moisture absorption material, and the heating module 30 can be an electric heating wire or a PTC heater. The moisture absorption fan 52 extracts gas from outdoor air C into the moisture absorption air duct 10, and when the extracted gas flows through the water storage rotating disc 40 in the moisture absorption air duct 10, the moisture is absorbed by the moisture absorption material, and the moisture absorption gas D is discharged from the moisture absorption air duct 10 to the outdoor environment F. The humidification fan 51 extracts gas from outdoor air C into the humidification air duct 20, and the gas first flows through the heating module 30 and then flows through the water storage rotating disc 40 in the humidification air duct 20. The heated air can absorb moisture from the moisture absorption material to form humidified gas E, which is then delivered to indoor environment G to increase the humidity of indoor environment G. The water storage rotating disc 40 has a moisture absorption zone A in the moisture absorption air duct 10 for absorbing moisture, and a desorption zone B in the humidification air duct 20 for releasing moisture; when the humidification mechanism is running, the water storage rotating disc 40 rotates between the moisture absorption air duct 10 and the humidification air duct 20 to rotate back and forth between the moisture absorption zone A and the desorption zone B to complete the transmission of moisture. In addition, the humidification mechanism can be used as a stand-alone humidifier or integrated into other devices such as air conditioners.

[0055] Referring to Fig. 3 ,Fig. 3 The flowchart of the first embodiment of the method for detecting air leakage of the humidification mechanism is shown in the figure. The first embodiment of the method for detecting air leakage of the humidification mechanism is proposed.

[0056] In the first embodiment, the method for detecting air leakage of the humidification mechanism comprises the following steps:

[0057] Step S10: Obtain the first temperature at the air outlet of the humidification air duct 20.

[0058] It should be understood that the execution subject of the embodiment is a humidification mechanism control device with data processing, data communication, and program running functions. The humidification mechanism control device can be an integrated controller or a client computer device, and of course, it can also be other devices with similar functions, which are not limited in the present embodiment.

[0059] It should be noted that the humidification mechanism enters the humidification mode when receiving the start instruction, which can be sent by the integrated controller or the client. For example, if the humidification mechanism is installed in an air conditioner, the user can send a humidification instruction to the air conditioner through a remote control or a mobile phone, and the controller in the air conditioner sends a start instruction to the humidification mechanism to make it enter the humidification mode.

[0060] Reference Fig. 4 , Fig. 4 Fig. 4 The structure diagram of an embodiment of the humidification mechanism is shown in the figure. Generally, the humidification mechanism is installed in multiple modules for splicing, for example, the humidification mechanism can be divided into three independent modules: a moisture absorption module, a material module, and a humidification module. The moisture absorption module includes a moisture absorption fan 52, part of the moisture absorption air duct 10, and part of the humidification air duct 20; the material module includes a water storage turntable 40; the humidification module includes a humidification fan 51, part of the moisture absorption air duct 10, and part of the humidification air duct 20. The heating mechanism 30 can be placed in the moisture absorption module, the material module, or the humidification module according to the flow direction of the humidification air duct 20, so that the humidified air passes through the heater first and then passes through the water storage turntable. The contact part between each module is installed with a material with sealing or damping effect, which plays a role in preventing rain, air leakage, and vibration when the modules are spliced together. Specifically, a soft polyvinyl chloride cover (refrigerator door seal) can be installed on the module contact surface.

[0061] It can be understood that due to installation errors or due to the aging of components during long-term operation of the humidification mechanism, the sealing of the humidification mechanism may be compromised, and air leakage may occur. If air leakage occurs in the humidification air duct 20, the humidified air mixes with the infiltrated air, reducing the humidity of the air outlet of the humidification air duct 20, resulting in poor humidification effect of the indoor environment. The air leakage detection in the present embodiment is mainly for detecting air leakage of the humidification air duct 20.

[0062] In a specific implementation, a temperature sensor can be arranged at the air outlet of the humidifying air duct 20 to detect the temperature of the air delivered by the humidifying air duct 20 to the indoor environment. Specifically, the temperature sensor is arranged in the humidifying air duct 20 close to the air outlet, and the humidifying mechanism control device receives the detection data fed back by the temperature sensor to obtain the first temperature at the air outlet of the humidifying air duct 20.

[0063] Step S20: When the first temperature is less than the first preset temperature, it is determined whether the heating state in the humidifying air duct 20 meets the preset heating condition.

[0064] It should be noted that in the case of air leakage in the humidifying air duct 20, the humidity of the air delivered by the humidifying air duct 20 to the indoor environment decreases, and the temperature also decreases, because the temperature of the air heated by the heating mechanism 30 is usually high, and the temperature decreases after absorbing part of the water after passing through the water storage turntable 40, but the temperature of the humidified air is still higher than that of the outdoor air under normal circumstances. Therefore, when the temperature of the humidified air is low, the humidifying air duct 20 may have air leakage.

[0065] The first preset temperature is used to determine whether the humidified air is below the normal value, for example, the normal temperature of the humidified air is 25℃, and the first preset temperature can be 20℃; if the temperature of the humidified air is less than the first preset temperature, it indicates that the humidifying air duct 20 may have air leakage.

[0066] As described above, if the humidifying air duct 20 leaks, the internal heat will be discharged, and the internal temperature will be lower than the normal working condition. Therefore, when it is detected that the temperature of the humidified air is abnormal, and there may be air leakage, the heating state in the humidifying air duct 20 can be detected to determine whether the humidifying air duct 20 leaks. The heating state mainly refers to the change state of the heat in the humidifying air duct 20. Under normal working conditions, the temperature at the heating mechanism in the humidifying air duct 20 is the highest, and the temperature difference before and after the water storage turntable 40 is large, and the temperature change between the water storage turntable 40 and the air outlet is small. The preset heating condition can be the temperature value that should be met by each part of the humidifying air duct 20 under normal working conditions. The temperature of each part in the humidifying air duct 20 can be detected, and then the detection value is compared with the normal working condition to determine whether the humidifying air duct 20 has air leakage.

[0067] Step S30: When the heating state does not meet the preset heating condition, it is determined that the humidifying mechanism has air leakage.

[0068] It can be understood that if the heating state does not meet the preset heating condition, it indicates that part of the positions in the humidifying air duct 20 do not reach the expected temperature, and the humidifying air duct 20 has outdoor air penetration, so it can be determined that the humidifying mechanism has air leakage.

[0069] In the first embodiment, the outflow temperature of the humidifying air duct 20 is detected to determine whether the humidifying mechanism is likely to have heat leakage; then the heating state in the humidifying air duct 20 is detected, and if the heating state does not satisfy the heating condition of the normal working condition, it indicates that the humidifying air duct has heat leakage, that is, there is air leakage, thereby realizing the air leakage detection of the humidifying mechanism and avoiding affecting the user experience.

[0070] Referring to Fig. 4 , Fig. 5 The flowchart of the second embodiment of the humidifying mechanism air leakage detection method of the present application is based on the first embodiment, and the second embodiment of the humidifying mechanism air leakage detection method of the present application is proposed.

[0071] In the second embodiment, before step S20, it further includes:

[0072] Step S11: obtaining the second temperature at the air inlet of the moisture absorption air duct 10.

[0073] It should be noted that since the air inlet of the humidifying air duct 20 is also the air in the outdoor environment, under the premise that the heating mechanism 30 maintains a stable heating power, the outflow temperature of the humidifying air duct 20 is also related to the temperature of the outdoor environment. Therefore, in order to accurately determine whether the air temperature delivered by the humidifying mechanism to the indoor environment is lower than the expected value, the corresponding first preset temperature also needs to be determined according to the temperature of the outdoor environment.

[0074] In specific implementation, since the moisture absorption air duct 10 and the humidifying air duct 20 also extract air from the outdoor environment, the temperature at the air inlet of the moisture absorption air duct 10 is the same as the temperature of the outdoor environment, that is, the second temperature actually reflects the temperature of the outdoor environment. By setting a temperature sensor at the air inlet of the moisture absorption air duct 10, the second temperature at the air inlet can be obtained. Of course, a temperature sensor can also be directly set at the air inlet of the outdoor environment or the humidifying air duct 20, and the temperature obtained can also reflect the temperature of the outdoor environment.

[0075] Step S12: determining the corresponding first preset temperature according to the second temperature and the preset mapping relationship.

[0076] It should be noted that the preset mapping relationship refers to the mapping relationship between the second temperature and the first preset temperature; for example, when the second temperature is less than 25℃, the first preset temperature is 20℃; when the second temperature is greater than 25℃ and less than 35℃, the first preset temperature is 30℃. At present, its specific value can be set according to user demand, and the present embodiment does not limit this.

[0077] Furthermore, in this embodiment, in step S20, determining whether the heating state within the humidification duct 20 meets the preset heating conditions can be as follows: when the second temperature is less than or equal to the second preset temperature, acquire the temperature dataset of the upstream air of the water storage disc 40 within the humidification duct 20 corresponding to a first preset time period. The temperature dataset includes at least one temperature data point. By comparing each temperature in the temperature dataset with a third preset temperature, a first comparison result is obtained; then, based on the first comparison result, it is determined whether the heating state within the humidification duct 20 meets the preset heating conditions.

[0078] It should be noted that when the outdoor air temperature is low, if there is air leakage in the humidification duct 20, the infiltrated cold air will mix with the humidified air, causing a temperature drop. Therefore, the reason for the low outlet air temperature of the humidification duct 20 when the heating mechanism 30 is heating normally is the infiltration of cold air. The second preset temperature is used to define whether the outdoor ambient temperature is low, and its specific value can be set according to user needs; this embodiment does not impose any restrictions on this.

[0079] The air upstream of the water storage turntable 40 refers to the air heated by the heating mechanism 30. The temperature of the heated air over a period of time can be used to determine whether the heating mechanism 30 is heating normally. Specifically, the first preset time period can be 5 minutes. During these 5 minutes, the temperature of the heated air is continuously or intermittently collected and compared with a third preset temperature. If any temperature in the temperature data set is greater than the third preset temperature, it indicates that the heating mechanism 30 is heating normally. If the outlet air temperature of the humidification duct 20 is low at this time, it indicates that cold air has seeped in, and the humidification mechanism 30 has air leakage.

[0080] It should be noted that the heating power of the heating mechanism 30 is related to the second temperature in practice. The higher the second temperature, the higher the heating power of the heating mechanism 30. Therefore, the third preset temperature can also be determined based on the second temperature. For example, when the second temperature is less than 25°C, the third preset temperature is 110°C; when the second temperature is greater than 25°C but less than 35°C, the first preset temperature is 130°C.

[0081] Understandably, if all temperatures in the temperature dataset are less than or equal to the third preset temperature, it indicates that the low outlet air temperature of the humidification duct 20 is due to abnormal heating of the heating mechanism 30. In this case, it can be determined that the air upstream of the water storage disc in the humidification duct is in an abnormal heating state. Simultaneously, an alarm can be triggered to the user for timely maintenance.

[0082] In the second embodiment, the outdoor environment temperature is detected to determine the boundary value corresponding to the outlet temperature of the humidifying air duct 20, so as to accurately determine whether the humidifying air duct 20 is likely to have air leakage. In addition, in the determination of whether the humidifying air duct is likely to have air leakage, the heating state of the heating mechanism 30 is detected. If the heating is normal, it indicates that the humidifying air duct 20 indeed has air leakage, so that the air leakage detection of the humidifying mechanism is more accurate, and the user experience is avoided.

[0083] Referring to Fig. 5 , Fig. 6 FIG. 2 is a flowchart of a third embodiment of the air leakage detection method of the humidifying mechanism according to the present application. Based on the first and second embodiments, the third embodiment of the air leakage detection method of the humidifying mechanism is provided.

[0084] In the third embodiment, step S20 comprises:

[0085] Step S201: When the second temperature is greater than the second preset temperature, the outlet is closed, and the temperature change value of the outlet in the second preset time period is obtained.

[0086] It should be noted that when the outdoor temperature is high, if the humidifying air duct 20 has outdoor air infiltration, since the temperature after humidification is relatively close to the temperature of the outdoor air, the influence of the mixture on the temperature after humidification is not obvious, and it is difficult to determine the air leakage possibility through the temperature drop after humidification. Therefore, in the second temperature greater than the second preset temperature, the heat accumulation method is used to determine whether the humidifying air duct 20 has outdoor air infiltration.

[0087] It can be understood that when the outlet is closed, the heating mechanism 30 continues to heat, and the heat accumulates at the outlet, causing the temperature to rise. When the humidifying air duct 20 has air leakage, the heat can be transmitted to the outdoor, and the temperature rising amplitude at the outlet is reduced. Therefore, the humidified air can be accumulated at the outlet by closing the outlet, and whether the humidifying air duct 20 has outdoor air infiltration can be determined according to the temperature rising amplitude.

[0088] It should be noted that since the heated air can absorb moisture from the water storage disc 40 to cool down, in order to avoid the interference of this factor on the air leakage detection, the water storage disc 40 needs to be controlled to stop rotating when the temperature change value is obtained.

[0089] In the specific implementation, the temperature change value of the outlet in the second preset time period in step S201 can be: obtaining the starting temperature of the outlet when the outlet is closed; obtaining the reference temperature of the outlet after the second preset time interval; and taking the difference between the starting temperature and the reference temperature as the temperature change value.

[0090] It should be noted that, since the temperature of the humidified air is too high to affect the service life of the humidification air duct 20, the second preset time period should not be too long to avoid the temperature of the air at the outlet being too high. Generally, the second preset time period can be 10S, 20S, and the specific value thereof can be set according to user demand, which is not limited in the embodiment.

[0091] Step S202: comparing the temperature change value with a preset value to obtain a second comparison result.

[0092] It should be noted that the specific value of the preset value can be determined according to the heating power of the heating mechanism 30 and the second preset time period; for example, if the heating power is low and the second preset time period is 10S, the preset value can be 5℃; if the heating power is high and the second preset time period is 10S, the preset value can be 10℃. At present, the specific value thereof can be set according to user demand, which is not limited in the embodiment.

[0093] Step S203: determining whether the heating state in the humidification air duct 20 meets a preset heating condition according to the second comparison result.

[0094] It can be understood that, when the second comparison result is that the temperature change value is greater than or equal to the preset value, it indicates that the temperature rise after humidification is large after the air outlet is closed, there is no heat leakage, that is, there is no outdoor air infiltration in the humidification air duct 20, and it is determined that the heating state in the humidification air duct 20 meets the preset heating condition. When the second comparison result is that the temperature change value is less than the preset value, it indicates that the temperature rise after humidification is small after the air outlet is closed, there is heat leakage, that is, there is outdoor air infiltration in the humidification air duct 20, and it is determined that the heating state in the humidification air duct 20 does not meet the preset heating condition.

[0095] In the third embodiment, when the temperature of the outdoor environment is high, the rising amplitude of the temperature after humidification is detected by closing the air outlet, whether there is heat leakage in the humidification air duct 20 is determined, whether there is air leakage in the humidification air duct 20 is determined, and the air leakage detection of the humidification mechanism is more accurately realized, thereby avoiding affecting the user experience.

[0096] In addition, the embodiment of the present application also proposes a storage medium, the storage medium has a humidification mechanism air leakage detection program stored thereon, and the humidification mechanism air leakage detection program is executed by a processor to realize the steps of the humidification mechanism air leakage detection method as described above. Since the storage medium can adopt all the technical solutions of the above-mentioned embodiments, it at least has the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0097] In addition, to achieve the above object, the application further provides an air conditioner comprising the humidification mechanism and the humidification mechanism control device.

[0098] In addition, with reference to Fig. 6 , ​ The structure block diagram of the first embodiment of the air leakage detection device of the humidification mechanism, and the application further provides an air leakage detection device of a humidification mechanism.

[0099] In the embodiment, the humidification mechanism has a moisture absorption air duct 10, a humidification air duct 20 and a water storage rotating disc 40, the water storage rotating disc 40 is partially located in the moisture absorption air duct 10 and partially located in the humidification air duct 20. The air leakage detection device of the humidification mechanism comprises:

[0100] The acquisition module 100 is configured to acquire a first temperature at an air outlet of the humidification air duct.

[0101] It should be noted that the humidification mechanism enters the humidification mode when receiving a start instruction, which can be sent by an integrated controller or a client. For example, if the humidification mechanism is arranged in an air conditioner, a user can send a humidification instruction to the air conditioner through a remote controller or a mobile phone, and then the controller in the air conditioner sends a start instruction to the humidification mechanism, so that the humidification mechanism enters the humidification mode.

[0102] Generally, the humidification mechanism is spliced by multiple modules during installation. For example, the humidification mechanism can be divided into three independent modules: a moisture absorption module, a material module and a humidification module. The moisture absorption module includes a moisture absorption fan 52, part of the moisture absorption air duct 10 and part of the humidification air duct 20; the material module includes the water storage rotating disc 40; and the humidification module includes a humidification fan 51, part of the moisture absorption air duct 10 and part of the humidification air duct 20. The heating mechanism 30 can be placed in the moisture absorption module, the material module or the humidification module according to the flow direction of the humidification air duct 20, so that the humidified air passes through the heater first and then passes through the water storage rotating disc. The contact part between each module is installed with a material having a sealing effect or a damping effect, which plays a role in preventing rain, air leakage and vibration after the modules are spliced together. Specifically, a soft polyvinyl chloride cover (refrigerator door seal) can be installed on the contact surface of the module.

[0103] It can be understood that due to installation errors or due to the aging of components during long-term operation of the humidification mechanism, the sealing performance of the humidification mechanism decreases, and the humidification mechanism may leak air. If the humidification air duct 20 leaks air, the humidified air mixes with the infiltrated air, which reduces the humidity of the air outlet of the humidification air duct 20 and leads to poor humidification effect of the indoor environment. The air leakage detection in the embodiment is mainly for the air leakage detection of the humidification air duct 20.

[0104] In a specific implementation, a temperature sensor can be arranged at the air outlet of the humidifying air duct 20 to detect the temperature of the air delivered by the humidifying air duct 20 to the indoor environment. Specifically, the temperature sensor is arranged in the humidifying air duct 20 close to the air outlet, and the detection data fed back by the temperature sensor is received by the collection module 100 to obtain the first temperature at the air outlet of the humidifying air duct 20.

[0105] The detection module 200 is configured to determine whether the heating state in the humidifying air duct meets a preset heating condition when the first temperature is less than a first preset temperature.

[0106] It should be noted that in the case of air leakage in the humidifying air duct 20, the humidity of the air delivered by the humidifying air duct 20 to the indoor environment decreases, and the temperature also decreases. This is because the temperature of the air heated by the heating mechanism 30 is usually high, and the temperature decreases after absorbing part of the water in the water storage turntable 40. However, under normal circumstances, the temperature of the humidified air is still higher than that of the outdoor air. Therefore, when the temperature of the humidified air is low, the humidifying air duct 20 may have air leakage.

[0107] The first preset temperature is used to determine whether the temperature of the humidified air is lower than the normal value. For example, the normal temperature of the humidified air is 25℃, and the first preset temperature can be 20℃. If the temperature of the humidified air is less than the first preset temperature, it indicates that the humidifying air duct 20 may have air leakage.

[0108] As mentioned above, air leakage in the humidifying air duct 20 will cause internal heat to leak out, and the internal temperature will be lower than the normal working condition. Therefore, when the temperature of the air outlet of the humidifying mechanism is detected to be abnormal, it is possible that there is air leakage. To determine whether the humidifying air duct 20 has air leakage, the heating state in the humidifying air duct 20 can be detected. The heating state mainly refers to the change state of the heat in the humidifying air duct 20. Under normal working conditions, the temperature at the heating mechanism in the humidifying air duct 20 is the highest, and the temperature difference before and after the water storage turntable 40 is large, and the temperature change between the water storage turntable 40 and the air outlet is small. The preset heating condition can be the temperature value that should be met by each part of the humidifying air duct 20 under normal working conditions. The temperature of each part in the humidifying air duct 20 can be detected, and then the detection value is compared with the normal working condition to determine whether the humidifying air duct 20 has air leakage.

[0109] The judgment module 300 is configured to determine that the humidifying mechanism has air leakage when the heating state does not meet the preset heating condition.

[0110] It can be understood that if the heating state does not meet the preset heating condition, it indicates that the temperature at some positions in the humidifying air duct 20 does not reach the expected temperature, and outdoor air has penetrated into the humidifying air duct 20, which can be determined as air leakage in the humidifying mechanism.

[0111] In the embodiment, whether the humidifying mechanism is possible to exist heat leakage is judged by detecting the outlet air temperature of the humidifying air duct 20; then the heating state in the humidifying air duct 20 is detected, if the heating state does not satisfy the heating condition of the normal working condition, it is indicated that the humidifying air duct exists heat leakage, that is, there is air leakage, so that the air leakage detection of the humidifying mechanism is realized, and the user experience is avoided from being affected.
