Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and particularly to an air conditioner and a method for processing the relative humidity of the environment of the air conditioner. Background Art

[0002] In people's daily life, air conditioners have become essential intelligent devices, which can realize various functions such as refrigeration, heating, and dehumidification. The control strategy of the air conditioner includes collecting the relative humidity of the indoor environment, and adjusting the air outlet wind speed and the operating frequency of the compressor according to the difference between the indoor environment relative humidity and the set humidity, so as to provide a comfortable indoor environment for users.

[0003] Generally, a humidity sensor is used to collect the relative humidity of the environment. In the prior art, in addition to setting a humidity sensor on the air conditioner housing, an external humidity sensor is also set, such as integrating a humidity sensor in the remote control of the air conditioner. Since the position of the remote control is closer to the user, the relative humidity of the environment collected by it is more conducive to the operation control of the air conditioner. However, there is also a situation where the remote control is covered, blocked or moved outdoors, resulting in inaccurate environmental information being collected or a large difference in the humidity information collected at different times, causing a drastic change in the wind speed or the compressor frequency, and abnormal operation of the air conditioner, which brings an unpleasant user experience to the user. Therefore, how to obtain accurate and stable relative humidity information of the environment is of great significance to the normal operation of the air conditioner. Summary of the Invention

[0004] The purpose of the embodiments of the present invention is to provide an air conditioner and a method for processing the relative humidity of the environment of the air conditioner, which can accurately and stably collect the relative humidity of the indoor environment of the air conditioner, improve the accuracy of the operation control of the air conditioner, and improve the user experience.

[0005] To achieve the above purpose, the embodiments of the present invention provide an air conditioner, including:

[0006] An indoor unit;

[0007] A body humidity sensor, disposed on the housing of the indoor unit, for collecting relative humidity information to obtain a first relative humidity;

[0008] An external humidity sensor, for collecting relative humidity information to obtain a second relative humidity;

[0009] A controller, connected to the body humidity sensor and the external humidity sensor, for:

[0010] After the air conditioner is powered on, if the second relative humidity is received, select the second relative humidity as the current environmental relative humidity;

[0011] During the operation of the air conditioner, if the first relative humidity and the second relative humidity are received simultaneously, calculate the difference between the first relative humidity and the second relative humidity in real time;

[0012] When the difference between the first relative humidity and the second relative humidity is greater than the first relative humidity threshold, calculate the average value of the first relative humidity and the second relative humidity as the current ambient relative humidity.

[0013] As an improvement to the above solution, when the difference between the first relative humidity and the second relative humidity is greater than the first relative humidity threshold, calculating the average value of the first relative humidity and the second relative humidity as the current ambient relative humidity is specifically:

[0019] Select the second relative humidity as the current ambient relative humidity and execute the step: calculate the difference between the first relative humidity and the second relative humidity in real time.

[0020] As an improvement to the above solution, the controller is further configured to:

[0021] During the operation of the air conditioner, if the situation changes from receiving both the first relative humidity and the second relative humidity or only receiving the second relative humidity to only receiving the first relative humidity, adjust the current ambient relative humidity at a third preset humidity change rate until the current ambient relative humidity is equal to the first relative humidity;

[0022] Select the first relative humidity as the current ambient relative humidity.

[0023] As an improvement to the above solution, after selecting the first relative humidity as the current ambient relative humidity, the controller is further configured to:

[0024] When the second relative humidity is received again, adjust the current ambient relative humidity at a third preset humidity change rate until the current ambient relative humidity is equal to the second relative humidity;

[0025] Select the second relative humidity as the current ambient relative humidity, and perform the step of: calculating the difference between the first relative humidity and the second relative humidity in real time.

[0026] As an improvement to the above solution, the controller is further configured to:

[0027] After the air conditioner is powered on or during operation, if the first relative humidity and the second relative humidity are not received, use a preset relative humidity value as the current ambient relative humidity.

[0028] As an improvement to the above solution, the controller is further configured to:

[0029] After the air conditioner is powered on, if only the first relative humidity is received, select the first relative humidity as the current ambient relative humidity;

[0030] During the operation of the air conditioner, when the second relative humidity is received again, adjust the current ambient relative humidity at a third preset humidity change rate until the current ambient relative humidity is equal to the second relative humidity;

[0031] Select the second relative humidity as the current ambient relative humidity, and perform the step of: calculating the difference between the first relative humidity and the second relative humidity in real time.

[0032] An embodiment of the present invention further provides a method for processing the ambient relative humidity of an air conditioner, where the air conditioner includes:

[0033] An indoor unit;

[0034] A body humidity sensor, disposed on the housing of the indoor unit, for collecting humidity information to obtain a first relative humidity;

[0035] A peripheral humidity sensor, for collecting humidity information to obtain a second relative humidity;

[0036] The method includes:

[0037] After the air conditioner is powered on, if the second relative humidity is received, select the second relative humidity as the current ambient relative humidity;

[0038] During the operation of the air conditioner, if the first relative humidity and the second relative humidity are received simultaneously, calculate the difference between the first relative humidity and the second relative humidity in real time;

[0039] When the difference between the first relative humidity and the second relative humidity is greater than the first relative humidity threshold, calculate the average value of the first relative humidity and the second relative humidity as the current ambient relative humidity.

[0040] As an improvement to the above solution, when the difference between the first relative humidity and the second relative humidity is greater than the first relative humidity threshold, calculating the average value of the first relative humidity and the second relative humidity as the current ambient relative humidity is specifically:

[0041] When the difference between the first relative humidity and the second relative humidity is greater than the first relative humidity threshold, calculate the average value of the first relative humidity and the second relative humidity;

[0042] Adjust the current ambient relative humidity at a first preset humidity change rate until the current ambient relative humidity is equal to the average value;

[0043] Select the average value as the current ambient relative humidity.

[0044] As an improvement to the above solution, after calculating the average value of the first relative humidity and the second relative humidity as the current ambient relative humidity, the method further includes:

[0045] When the difference between the first relative humidity and the second relative humidity is less than the second relative humidity threshold, adjust the current ambient relative humidity at a second preset humidity change rate until the current ambient relative humidity is equal to the second relative humidity;

[0046] Select the second relative humidity as the current ambient relative humidity and execute the step: calculate the difference between the first relative humidity and the second relative humidity in real time.

[0047] Compared with the prior art, the air conditioner and the method for processing the ambient relative humidity of the air conditioner disclosed in the present invention. The air conditioner includes a body humidity sensor for collecting the first relative humidity, and also includes a peripheral humidity sensor for collecting the second relative humidity. After the air conditioner is powered on, if the second relative humidity is received, the second relative humidity is selected as the current ambient relative humidity; during the operation of the air conditioner, if both the first relative humidity and the second relative humidity are received, the difference between the first relative humidity and the second relative humidity is calculated in real time; when the difference between the first relative humidity and the second relative humidity is greater than the first relative humidity threshold, the average value of the first relative humidity and the second relative humidity is calculated as the current ambient relative humidity. By adopting the technical means of the embodiment of the present invention, the air conditioner preferentially uses the second relative humidity collected by the peripheral humidity sensor as the current ambient relative humidity to execute the operation strategy of the air conditioner, so that the ambient relative humidity used by the air conditioner when executing the control strategy is closer to the ambient relative humidity at the user's location. Therefore, parameters such as the adjusted wind speed and humidification amount of the air conditioner can better meet the requirements of the user, providing a comfortable environment for the user. Moreover, when the first relative humidity and the second relative humidity differ greatly, the average value of the two is selected as the current ambient relative humidity, which can make the value of the current ambient relative humidity adopted by the air conditioner closer to the actual environmental situation, avoiding the situation that when the humidity information collected by the peripheral humidity sensor is inaccurate under special circumstances, using the second relative humidity as the current ambient relative humidity is likely to lead to inaccurate operation control of the air conditioner, and at the same time avoiding directly switching the current ambient relative humidity to the first relative humidity, resulting in too large a difference in the ambient relative humidity value adopted by the air conditioner, causing violent changes in the wind speed or compressor frequency and abnormal operation of the air conditioner. By adopting the embodiment of the present invention, the air conditioner can obtain a relatively accurate and stable ambient relative humidity value, effectively improving the accuracy of air conditioner operation control and enhancing the user experience.

[0058] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0059] An embodiment of the present invention provides an air conditioner 10, which can be used to perform functions such as refrigeration, heating, and / or dehumidification.

[0060] In an alternative embodiment, referring to Figure 1 , it is a schematic structural diagram of an air conditioner in the first preferred embodiment of the present invention. The air conditioner is a split-type air conditioner, including an indoor unit 20 and an outdoor unit 30. The indoor unit 20 includes a blowing device such as an air outlet, and the outdoor unit 30 includes a functional system composed of devices such as a compressor, an evaporator, and a condenser. The specific structures and working principles of the indoor unit 20 and the outdoor unit 30 of the split-type air conditioner can refer to the prior art and will not be elaborated here.

[0061] In another embodiment, the air conditioner is an integrated air conditioner, including an indoor unit. The indoor unit integrates a blowing device such as an air outlet and a functional system composed of a compressor, etc. The specific structures and working principles of the integrated air conditioner can refer to the prior art and will not be elaborated here.

[0062] The air conditioner 10 further includes a body humidity sensor 21 and a peripheral humidity sensor 40. The body humidity sensor 21 is disposed on the housing of the indoor unit 20. The body humidity sensor 21 can collect the humidity information of the current location, serving as the first relative humidity RH1.

[0063] The peripheral humidity sensor 40 is not disposed on the housing of the air conditioner. Optionally, referring to Figure 2 , which is a schematic structural diagram of the air conditioner in the second preferred embodiment of the present invention. The air conditioner 10 further includes a remote controller 50. The remote controller 50 is an independent device that can communicate with the air conditioner, receive control instructions from the user for the air conditioner, and achieve the operation control of the air conditioner. Then the peripheral humidity sensor 40 can be disposed in the remote controller 50. The peripheral humidity sensor can collect the humidity information of the current location, serving as the second relative humidity RH2.

[0064] Of course, the peripheral humidity sensor 40 can also be disposed in a device independent of the air conditioner, such as an indoor humidifier, an indoor hygrometer, etc., without affecting the beneficial effects of the present invention.

[0065] The air conditioner 10 further includes a controller. The controller can be disposed in the air conditioner 10 for achieving the operation control of the air conditioner 10. The controller is respectively connected and communicates with the body humidity sensor 21 and the peripheral humidity sensor 40, so as to receive the first relative humidity RH1 sent by the body humidity sensor 21 and the second relative humidity RH2 sent by the peripheral humidity sensor 40.

[0066] It should be noted that the communication between the controller and the body humidity sensor 21 and the peripheral humidity sensor 40 can adopt an infrared signal communication method, a Bluetooth communication method, a wifi communication method. Of course, other wired or wireless communication methods can also be adopted, which are not specifically limited herein.

[0067] As an example, taking the air conditioner 10 including the remote controller 50 as an example, the remote controller 50 is provided with a peripheral humidity sensor 40. The remote controller 50 automatically sends an infrared signal at regular intervals (for example, every 1 minute) for transmitting the second relative humidity value to the controller.

[0068] Referring to Figure 3 , which is a schematic flowchart of the work performed by the controller in the first preferred embodiment of the present invention. The controller is used to execute steps S11 to S13:

[0069] S11. After the air conditioner is powered on, if the second relative humidity is received, select the second relative humidity as the current ambient relative humidity;

[0070] S12. During the operation of the air conditioner, if the first relative humidity and the second relative humidity are received simultaneously, calculate the difference between the first relative humidity and the second relative humidity in real time;

[0071] S13. When the difference between the first relative humidity and the second relative humidity is greater than the first relative humidity threshold, calculate the average value of the first relative humidity and the second relative humidity as the current ambient relative humidity.

[0072] In the embodiment of the present invention, when the air conditioner 10 is powered on, if the controller can receive the second relative humidity RH2, including two cases: only receiving the second relative humidity RH2 sent by the peripheral humidity sensor 40, and receiving the first relative humidity RH1 sent by the body humidity sensor 21 and the second relative humidity RH2 sent by the peripheral humidity sensor 40 simultaneously, the second relative humidity RH2 is selected as the current ambient relative humidity and substituted into the self-owned operation strategy of the air conditioner to realize the operation control of the air conditioner. Of course, the current ambient relative humidity will be updated in real time according to the second relative humidity collected by the peripheral humidity sensor 40 in real time.

[0073] During the operation of the air conditioner, if the air conditioner only receives the second relative humidity RH2 sent by the peripheral humidity sensor 40, then the second relative humidity RH2 is always used as the current ambient relative humidity.

[0074] During the operation of the air conditioner, if the controller receives the first relative humidity RH1 sent by the body humidity sensor 21 and the second relative humidity RH2 sent by the peripheral humidity sensor 40 simultaneously, calculate the difference between the first relative humidity RH1 and the second relative humidity RH2 in real time, and correct the value of the current ambient relative humidity according to the difference between the first relative humidity RH1 and the second relative humidity RH2.

[0075] Specifically, determine the first relative humidity threshold ΔRH1. When the difference between the first relative humidity and the second relative humidity is greater than the first relative humidity threshold, that is, when |RH1 - RH2| > ΔRH1, calculate the average value RHavg of the first relative humidity and the second relative humidity as the current ambient relative humidity, and substitute it into the self-owned operation strategy of the air conditioner, where RHavg = (RH1 + RH2) / 2.

[0076] Preferably, in order to make the processing of the current ambient relative humidity more accurate and avoid frequent adjustment, set the first preset duration t1. Then step S13 is specifically: when the difference between the first relative humidity and the second relative humidity is greater than the first relative humidity threshold and lasts for the first preset duration, calculate the average value of the first relative humidity and the second relative humidity as the current ambient relative humidity.

[0077] Understandably, the first preset duration t1 can be set according to the actual situation. For example, set t1 = 1 minute.

[0078] Understandably, after the air conditioner is powered on and operates with the second relative humidity as the current ambient relative humidity, if the difference between the first relative humidity and the second relative humidity always satisfies being less than or equal to the first relative humidity threshold, that is, satisfies |RH1 - RH2| ≤ ΔRH1, then the received second relative humidity RH2 is always used as the current ambient relative humidity.

[0079] It should be noted that the first relative humidity threshold ΔRH1 is a pre-set humidity value, which can be set according to the actual application situation. As an example, set the first relative humidity threshold ΔRH1 to 10%. Then, if |RH1 - RH2| > 10%, the average value RHavg of the first relative humidity and the second relative humidity is calculated and used as the current ambient relative humidity.

[0080] Of course, the above scenarios are only examples. In actual applications, the specific value of the first relative humidity threshold can be set according to the actual situation, and no specific limitation is made here.

[0081] By adopting the technical means of the embodiments of the present invention, the air conditioner preferentially uses the second relative humidity collected by the peripheral humidity sensor as the current ambient relative humidity to execute the operation strategy of the air conditioner, so that the ambient relative humidity used by the air conditioner when executing the control strategy is closer to the ambient relative humidity of the user's location. Therefore, parameters such as the adjusted wind speed and humidification amount of the air conditioner can better meet the requirements of the user and provide a comfortable environment for the user. Moreover, when the first relative humidity and the second relative humidity differ greatly, the average value of the two is selected as the current ambient relative humidity, which can make the value of the current ambient relative humidity adopted by the air conditioner closer to the actual environmental situation, and avoid the situation that when the humidity information collected by the peripheral humidity sensor is inaccurate in special cases, using the second relative humidity as the current ambient relative humidity is likely to lead to inaccurate operation control of the air conditioner. At the same time, it also avoids directly switching the current ambient relative humidity to the first relative humidity, resulting in too large a difference in the ambient relative humidity value adopted by the air conditioner, causing violent changes in the wind speed or compressor frequency and abnormal operation of the air conditioner. By adopting the embodiments of the present invention, the air conditioner room can obtain a relatively accurate and stable ambient relative humidity value, improve the accuracy of air conditioner operation control, and improve the user experience.

[0082] Preferably, refer to Figure 4, which is a schematic flowchart of the work executed by the controller in the second preferred embodiment of the embodiments of the present invention. Step S13, that is, when the difference between the first relative humidity and the second relative humidity is greater than the first relative humidity threshold, calculate the average value of the first relative humidity and the second relative humidity as the current ambient relative humidity, specifically including steps S131 to S133:

[0083] S131. When the difference between the first relative humidity and the second relative humidity is greater than the first relative humidity threshold, calculate the average value of the first relative humidity and the second relative humidity;

[0084] S132. Adjust the current ambient relative humidity at a first preset humidity change rate until the current ambient relative humidity is equal to the average value;

[0085] S133. Select the average value as the current ambient relative humidity.

[0086] In the embodiments of the present invention, a first preset humidity change rate r1 is preset. When |RH1 - RH2| > ΔRH1 is satisfied, calculate the average value RHavg of the first relative humidity and the second relative humidity. However, instead of directly switching the current ambient relative humidity to the average value RHavg, the current ambient relative humidity is gradually adjusted at the first preset humidity change rate r1 until the current ambient relative humidity is equal to the average value.

[0087] As an example, set r1 to 1% RH / min. That is, assume that the current ambient relative humidity is 50% and the calculated average value RHavg is 55%. Then, with 1% as the adjustment step and 1 minute as the adjustment period, increase the current ambient relative humidity until the current ambient relative humidity reaches 55%. Of course, the first preset humidity change rate r1 can be set according to the actual situation and is not specifically limited herein.

[0088] By adopting the technical means of the embodiments of the present invention, using a preset humidity change rate to adjust the value of the current ambient relative humidity can effectively avoid the situation that the ambient relative humidity value adopted by the air conditioner fluctuates too much before and after direct switching, and can avoid the parameters such as the air volume of the air conditioner and the operating frequency of the compressor from changing too much before and after, resulting in abnormal operation of the air conditioner or generating a large amount of noise, which affects the user experience.

[0089] Preferably, after step S13, the controller is further configured to: push a preset prompt message to remind the user to perform an abnormality detection.

[0090] That is, when the difference between the first relative humidity RH1 and the second relative humidity RH2 is large and satisfies |RH1 - RH2| > ΔRH1, it indicates that there is an abnormality in the main body humidity sensor 21 and / or the peripheral humidity sensor 40. Therefore, by pushing the corresponding prompt message, the user is reminded to check whether the main body humidity sensor fails or whether the position of the peripheral humidity sensor is reasonable, etc., so that the difference between the first relative humidity RH1 and the second relative humidity RH2 returns to the normal range.

[0091] It can be understood that the module for displaying the prompt message can be set on the indoor unit housing, or on the remote controller, or on the mobile terminal of the user that establishes a communication connection with the air conditioner, which is convenient for the user to view the prompt message in a timely and intuitive manner.

[0092] As a preferred implementation manner, refer to Figure 5 , which is a schematic flowchart of the work performed by the controller in the third preferred embodiment of the embodiments of the present invention. The embodiments of the present invention are further implemented on the basis of the above embodiments. After performing step S13, that is, calculating the average value of the first relative humidity and the second relative humidity as the current ambient relative humidity, the controller is further configured to perform step S14:

[0093] S14. When the difference between the first relative humidity and the second relative humidity is less than the second relative humidity threshold, adjust the current ambient relative humidity at a second preset humidity change rate until the current ambient relative humidity is equal to the second relative humidity; select the second relative humidity as the current ambient relative humidity.

[0094] In the embodiments of the present invention, a second relative humidity threshold ΔRH2 is set. When |RH1 - RH2| > ΔRH1, the average value of the two relative humidities is obtained as the current ambient relative humidity. When the difference between the first relative humidity RH1 and the second relative humidity RH2 shrinks and satisfies |RH1 - RH2| < ΔRH2, the air conditioner 10 still preferentially uses the second relative humidity RH2 as the current ambient relative humidity and substitutes it into the self-owned operation strategy of the air conditioner for air conditioner operation control.

[0095] In order to avoid large fluctuations in the ambient relative humidity value adopted by the air conditioner when directly switching to the second relative humidity RH2, in the embodiments of the present invention, when |RH1 - RH2| < ΔRH2 is satisfied, the current ambient relative humidity is adjusted at the second preset humidity change rate r2 until the current ambient relative humidity is equal to the second relative humidity RH2. After that, the second relative humidity RH2 collected in real time is used as the current ambient relative humidity and substituted into the self-owned operation strategy of the air conditioner. Then, step S12 is re-executed to calculate the difference between the first relative humidity and the second relative humidity, and the current ambient relative humidity is determined in the manner of the above embodiments.

[0096] As an example, r2 is set to 1% RH / min. That is, assuming that the current ambient relative humidity is 50% and the second relative humidity RH2 is 55%, the current ambient relative humidity is increased at an adjustment step of 1% and an adjustment period of 1 minute until the current ambient relative humidity reaches 55%. Of course, the second preset humidity change rate r2 can be set according to the actual situation and is not specifically limited herein.

[0097] It should be noted that the second relative humidity threshold ΔRH2 is a preset humidity value, which can be set according to the actual application situation. As an example, the second relative humidity threshold ΔRH2 is set to 5%. Then, if |RH1 - RH2| < 5%, the current ambient relative humidity is adjusted at the second preset humidity change rate r2 until the current ambient relative humidity is equal to the second relative humidity RH2, which is used as the current ambient relative humidity of the air conditioner.

[0098] Of course, the above scenario is only an example. In actual applications, the specific value of the second relative humidity threshold can be set according to the actual situation and is not specifically limited herein.

[0099] As a preferred embodiment, refer to Figure 6 , which is a schematic flowchart of the work executed by the controller in the fourth preferred embodiment in the embodiments of the present invention. The embodiments of the present invention are further implemented on the basis of any of the above embodiments, and the controller is further configured to execute step S21:

[0100] S21. During the operation of the air conditioner, if the situation changes from receiving the first relative humidity and the second relative humidity simultaneously, or only receiving the second relative humidity, to only receiving the first relative humidity, the current ambient relative humidity is adjusted at the third preset humidity change rate until the current ambient relative humidity is equal to the first relative humidity; the first relative humidity is selected as the current ambient relative humidity.

[0101] The controller obtains the first relative humidity RH1 collected by the body humidity sensor 21 and the second relative humidity RH2 collected by the peripheral humidity sensor 40 in real time. However, there may be a situation where the peripheral humidity sensor 40 fails or is in an abnormal state, resulting in the inability to collect the second relative humidity RH2, or the peripheral humidity sensor 40 is disconnected from the controller, causing the controller to be unable to obtain the second relative humidity RH2 collected by the peripheral humidity sensor 40. For example, taking the air conditioner 10 including the remote controller 50 as an example, the peripheral humidity sensor 40 is provided on the remote controller 50, and the remote controller 50 automatically sends an infrared signal once at regular intervals for transmitting the second relative humidity value to the controller. When the remote controller 50 is too far away from the air conditioner controller, or the remote controller 50 is blocked or has insufficient power and other abnormal situations, the controller cannot receive the infrared signal of the remote controller 50, resulting in the inability to receive the second relative humidity RH2.

[0102] In an embodiment of the present invention, when the controller only receives the first relative humidity RH1 collected by the body humidity sensor 21 and cannot receive the second relative humidity RH2 collected by the peripheral humidity sensor 40, the air conditioner 10 switches to using the first relative humidity RH1 as the current ambient relative humidity and substitutes it into the self-owned operation strategy of the air conditioner for air conditioner operation control.

[0103] In order to avoid the direct switch to the first relative humidity RH1 resulting in too large fluctuations in the ambient relative humidity value adopted by the air conditioner, in an embodiment of the present invention, when the second relative humidity RH2 cannot be received, the current ambient relative humidity is adjusted at a third preset humidity change rate r3 until the current ambient relative humidity is equal to the first relative humidity RH1, and then the first relative humidity RH1 collected in real time is used as the current ambient relative humidity and substituted into the self-owned operation strategy of the air conditioner.

[0104] As an example, set r3 to 1% RH / min. That is, assuming that the current ambient relative humidity is 55% and the first relative humidity RH1 is 50%, then with 1% as the adjustment step and 1 minute as the adjustment period, the current ambient relative humidity is reduced until the current ambient relative humidity reaches 50%. Of course, the third preset humidity change rate r3 can be set according to the actual situation and is not specifically limited herein.

[0105] Preferably, in order to make the processing of the current ambient relative humidity more accurate and avoid frequent adjustment, a second preset duration t2 is set. Then step S21 is specifically: during the operation of the air conditioner, when only the first relative humidity is received within the continuous second preset duration, the current ambient relative humidity is adjusted at a third preset humidity change rate until the current ambient relative humidity is equal to the first relative humidity; select the first relative humidity as the current ambient relative humidity.

[0106] Understandably, the second preset duration t2 can be set according to the actual situation. For example, t2 = 12 minutes is set.

[0107] As a preferred embodiment, refer to Figure 7 , which is a schematic flowchart of the work executed by the controller in the fifth preferred embodiment in the embodiments of the present invention. The embodiments of the present invention are further implemented on the basis of the previous embodiment. After step S21, the controller is further configured to execute step S22:

[0108] S22. When the second relative humidity is received again, adjust the current ambient relative humidity at a third preset humidity change rate until the current ambient relative humidity is equal to the second relative humidity; select the second relative humidity as the current ambient relative humidity.

[0109] In the embodiments of the present invention, after only the first relative humidity RH1 is received and the first relative humidity RH1 is selected as the current ambient relative humidity, if the controller receives the second relative humidity RH2 collected by the peripheral humidity sensor 40 again, the air conditioner 10 still preferentially uses the second relative humidity RH2 as the current ambient relative humidity. To avoid the direct switch to the second relative humidity RH2 causing too large fluctuations in the ambient relative humidity value adopted by the air conditioner, the current ambient relative humidity is also adjusted at a third preset humidity change rate r3 until the current ambient relative humidity is equal to the second relative humidity RH2, and then the second relative humidity RH2 collected in real time is used as the current ambient relative humidity and substituted into the self-owned operation strategy of the air conditioner. Then, step S12 is executed again to calculate the difference between the first relative humidity and the second relative humidity, and the current ambient relative humidity is determined in the manner of the above embodiment.

[0110] As a preferred embodiment, the embodiments of the present invention are further implemented on the basis of any of the above embodiments, and the controller is further configured to execute step S23:

[0111] S23. After the air conditioner is powered on or during operation, if the first relative humidity and the second relative humidity are not received, use a preset relative humidity value as the current ambient relative humidity.

[0112] The controller obtains in real time the first relative humidity RH1 collected by the body humidity sensor 21 and the second relative humidity RH2 collected by the peripheral humidity sensor 40. However, there may be a situation where neither the first relative humidity RH1 collected by the body humidity sensor 21 nor the second relative humidity RH2 collected by the peripheral humidity sensor 40 is received simultaneously. For example, the body humidity sensor 21 fails or is in an abnormal state, resulting in the inability to collect the first relative humidity RH1, or the body humidity sensor 21 is disconnected from the controller, causing the controller to be unable to obtain the first relative humidity RH1 collected by the body humidity sensor 21; the peripheral humidity sensor 40 fails or is in an abnormal state, resulting in the inability to collect the second relative humidity RH2, or the peripheral humidity sensor 40 is disconnected from the controller, causing the controller to be unable to obtain the second relative humidity RH2 collected by the peripheral humidity sensor 40.

[0113] In the embodiment of the present invention, when the controller does not receive the first relative humidity and the second relative humidity simultaneously, a preset relative humidity value is used as the current ambient relative humidity. The preset relative humidity value is a pre-set simulated relative humidity value, which can be analyzed and set according to specific situations such as the environmental parameters where the air conditioner is located and the application place of the air conditioner, and no specific limitation is made here.

[0114] Optionally, after step S23, the controller is further configured to: send a corresponding prompt message to remind the user to check and repair the air conditioner.

[0115] As a preferred embodiment, see Figure 8 , which is a schematic flowchart of the work performed by the controller in the sixth preferred embodiment of the embodiment of the present invention. The embodiment of the present invention is further implemented on the basis of any of the above embodiments, and the controller is further configured to execute step S31:

[0116] S31. After the air conditioner is powered on, if only the first relative humidity is received, select the first relative humidity as the current ambient relative humidity.

[0117] Further, see Figure 9 , which is a schematic flowchart of the work performed by the controller in the seventh preferred embodiment of the embodiment of the present invention.

[0118] After step S31, the controller is further configured to execute steps S32 and S33:

[0119] S32. During the operation of the air conditioner, when the second relative humidity is received again, adjust the current ambient relative humidity at a third preset humidity change rate until the current ambient relative humidity is equal to the second relative humidity;

[0120] S33. Select the second relative humidity as the current ambient relative humidity.

[0121] In an embodiment of the present invention, when the air conditioner 10 is powered on, assuming that the external humidity sensor 40 is in a faulty or abnormal state, or the external humidity sensor 40 is disconnected from the controller, such that the controller only receives the first relative humidity RH1 collected by the body humidity sensor 21 and cannot receive the second relative humidity RH2 collected by the external humidity sensor 40, then the first relative humidity RH1 is selected as the current ambient relative humidity and is brought into the self-owned operation strategy of the air conditioner to achieve the operation control of the air conditioner.

[0122] After that, during the operation of the air conditioner, if the external humidity sensor 40 returns to normal, or the controller re-establishes a connection with the external humidity sensor 40, and the controller can receive the second relative humidity RH2 collected by the external humidity sensor 40 again, then the air conditioner 10 still preferentially uses the second relative humidity RH2 as the current ambient relative humidity. To avoid the direct switch to the second relative humidity RH2 causing too large fluctuations in the ambient relative humidity value used by the air conditioner, the current ambient relative humidity is also adjusted at the third preset humidity change rate r3 until the current ambient relative humidity is equal to the second relative humidity RH2, and then the second relative humidity RH2 collected in real time is used as the current ambient relative humidity and is brought into the self-owned operation strategy of the air conditioner. After that, step S12 is executed again to calculate the difference between the first relative humidity and the second relative humidity, and the current ambient relative humidity is determined in the manner of the above embodiment.

[0123] By adopting the technical means of the embodiment of the present invention, the air conditioner preferentially uses the second relative humidity collected by the external humidity sensor as the current ambient relative humidity. If the second relative humidity cannot be received, the first relative humidity collected by the body humidity sensor is used as the current ambient relative humidity. Moreover, during the switching process between the two humidities, it is gradually adjusted at a certain humidity change rate, effectively avoiding the humidity fluctuations caused by direct switching, enabling the air-conditioned room to obtain a relatively accurate and stable ambient relative humidity value, and improving the accuracy of the operation control of the air conditioner.

[0124] See Figure 10 , which is a schematic flowchart of a method for processing the ambient relative humidity of an air conditioner in an embodiment of the present invention. The embodiment of the present invention also provides a method for processing the ambient relative humidity of an air conditioner, and the air conditioner includes:

[0125] An indoor unit; a body humidity sensor provided on the housing of the indoor unit for collecting humidity information to obtain a first relative humidity; an external humidity sensor for collecting humidity information to obtain a second relative humidity;

[0126] The method for processing the ambient relative humidity includes steps S41 to S43:

[0127] S41. After the air conditioner is powered on, if the second relative humidity is received, select the second relative humidity as the current ambient relative humidity;

[0128] S42. During the operation of the air conditioner, if both the first relative humidity and the second relative humidity are received, calculate the difference between the first relative humidity and the second relative humidity in real time;

[0129] S43. When the difference between the first relative humidity and the second relative humidity is greater than the first relative humidity threshold, calculate the average value of the first relative humidity and the second relative humidity as the current ambient relative humidity.

[0130] By adopting the technical means of the embodiment of the present invention, the air conditioner preferentially uses the second relative humidity collected by the peripheral humidity sensor as the current ambient relative humidity to execute the operation strategy of the air conditioner, so that the ambient relative humidity used by the air conditioner when executing the control strategy is closer to the ambient relative humidity at the user's location. Therefore, parameters such as the adjusted wind speed and humidification amount of the air conditioner can better meet the requirements of the user and provide a comfortable environment for the user. Moreover, when the first relative humidity and the second relative humidity differ greatly, selecting the average value of the two as the current ambient relative humidity can make the value of the current ambient relative humidity adopted by the air conditioner closer to the actual environmental situation, avoiding the situation that when the humidity information collected by the peripheral humidity sensor is inaccurate in special cases, using the second relative humidity as the current ambient relative humidity is likely to lead to inaccurate operation control of the air conditioner. At the same time, it also avoids directly switching the current ambient relative humidity to the first relative humidity, resulting in too large a difference in the ambient relative humidity value adopted by the air conditioner, causing violent changes in the wind speed or compressor frequency and abnormal operation of the air conditioner. By adopting the embodiment of the present invention, the air conditioner can obtain a relatively accurate and stable ambient relative humidity value, improve the accuracy of air conditioner operation control, and improve the user experience.

[0131] Preferably, after step S43, the method further includes step S44:

[0132] When the difference between the first relative humidity and the second relative humidity is less than the second relative humidity threshold, adjust the current ambient relative humidity at a second preset humidity change rate until the current ambient relative humidity is equal to the second relative humidity; select the second relative humidity as the current ambient relative humidity.

[0133] Preferably, the method further includes steps S45 and S46:

[0134] S45. During the operation of the air conditioner, if the first relative humidity and the second relative humidity are received simultaneously, or only the second relative humidity is received, and then it changes to only receiving the first relative humidity, adjust the current ambient relative humidity at a third preset humidity change rate until the current ambient relative humidity is equal to the first relative humidity; select the first relative humidity as the current ambient relative humidity.

[0135] S46. When the second relative humidity is received again, adjust the current ambient relative humidity at a third preset humidity change rate until the current ambient relative humidity is equal to the second relative humidity; select the second relative humidity as the current ambient relative humidity.

[0136] It should be noted that an ambient relative humidity processing method provided in an embodiment of the present invention has the same all process steps as those executed by a controller of an air conditioner in the above embodiment, and their working principles and beneficial effects correspond one by one, so they will not be elaborated herein.
