[0037] In combination Figure 1-1 And Figure 1-2As shown, the air conditioner includes an indoor fan 11 and a water washing device 12. The indoor fan 11 includes a fan blade 111 and an air duct 112. The water washing device 12 includes a water tank part 121 and a refrigeration part 122. The water tank part 121 is provided with an atomizing sheet and contains water, and the refrigeration part 122 is provided with refrigeration devices. The water tank part 121 is connected with the refrigeration part 122. The refrigeration part 122 of the water washing device 12 is detachably installed on the air inlet side of the indoor fan 11, and is used for cleaning the fan blade 111 and the air duct 112 of the indoor fan 11. The water in the water tank part 121 can be manually sucked by an external device, or can be generated by the air conditioner.

[0038] Optionally, the air duct 112 of the indoor fan 11 is provided with a hydrophobic film, and the bottom of the air duct 112 is provided with a drain hole 113. During the self-cleaning process of the indoor fan 11, the condensed water cannot be attached to the air duct 112 under the action of the hydrophobic film, and flows out from the drain hole 113 at the bottom of the air duct 112 under the action of gravity.

[0039] Optionally, the water tank part 121 is provided with an air inlet 1211 away from the indoor fan 11. Air flows through the water tank part 121 and the refrigeration part 122 from the air inlet 1211 and then enters the indoor fan 11.

The dust removal box 13 is detachably arranged on the air conditioner and located below the drain hole 113, and is used for collecting the water flowing out of the drain hole 113. After each self-cleaning is completed, the user needs to manually disassemble and clean the dust removal box 13.

[0041] In combination Figure 2 As shown, the disclosure embodiment provides a method for air conditioner fan self-cleaning, comprising:

[0042] S210, the air conditioner detects the attachment amount of pollutants of the indoor fan.

[0043] S230, in the case that the attachment amount of pollutants is greater than or equal to the set threshold, the air conditioner controls the water washing device to run, and controls the indoor fan to rotate, to realize the self-cleaning of the fan blade and the air duct of the indoor fan.

[0044] By using the method for air conditioner fan self-cleaning provided by the disclosure embodiment, the attachment amount of pollutants of the indoor fan is detected to determine the pollution condition of the indoor fan. In the case that the attachment amount of pollutants is greater than or equal to the set threshold, the pollution condition of the indoor fan is serious and needs to be self-cleaned. The water washing device is controlled to run, and the indoor fan is controlled to rotate, to realize the self-cleaning of the fan blade and the air duct. During the self-cleaning process, the fan blade and the air duct are cleaned by the water washing device, so as to improve the self-cleaning effect of the indoor fan.

[0045] Optionally, the amount of pollutants attached to the indoor fan in step S210 includes the amount of pollutants attached to the fan blade and / or the amount of pollutants attached to the air duct. In this way, when only the fan blade or the air duct is detected, the detection device used is less, and the cost and weight of the air conditioner can be reduced. When the fan blade and the air duct are detected, the accuracy of the detection can be improved, and the cleaning time of each part can be adjusted according to the respective pollution conditions to improve the cleaning effect.

[0046] When the amount of pollutants attached to the indoor fan in step S210 is the amount of pollutants attached to the fan blade and the amount of pollutants attached to the air duct, the amount of pollutants in step S230 can be the average of the two amounts of pollutants or any one of the amounts of pollutants.

[0047] The detection method of the amount of pollutants attached to the indoor fan in step S210 is a detection method in the prior art. The distribution and quantity of pollutants can be detected by using a corresponding sensor or instrument, and the amount of pollutants can be determined according to a preset relationship. The parameters of the indoor fan can also be detected, and the amount of pollutants can be determined by calculation according to a corresponding formula.

[0048] In combination Figure 3 As shown in the drawings, the embodiment of the present disclosure provides another method for self-cleaning of an air conditioner fan, which comprises:

[0049] S210, the air conditioner detects the amount of pollutants attached to the indoor fan.

[0050] S220, the air conditioner determines whether the amount of pollutants is greater than or equal to a set threshold value. If yes, step S231 is performed. If no, step S210 is returned.

[0051] S231, the air conditioner controls the water washing device to generate water vapor.

[0052] S232, the air conditioner controls the indoor fan to rotate forward, so that the water vapor is distributed throughout the fan blade and the air duct of the indoor fan.

[0053] S233, in the case where the water washing device is controlled to generate water vapor for a first set time t1, the air conditioner controls the water washing device to refrigerate to condense the water vapor.

[0054] S234, the air conditioner controls the indoor fan to rotate reversely, so that the condensed water is distributed throughout the fan blade and the air duct of the indoor fan.

[0055] S235, in the case where the water washing device is controlled to refrigerate for a second set time t2, the air conditioner adjusts the speed of the rotation of the indoor fan to clean the fan blade of the indoor fan.

[0056] S236, in the case that the fan blade of the indoor fan reaches the third set time t3 in the cleaning chamber, the air conditioner adjusts the speed of the indoor fan rotation, and periodically adjusts the direction of the indoor fan rotation, to clean the air duct of the indoor fan.

[0057] The method for air conditioner fan self-cleaning provided by the embodiments of the present disclosure is adopted, when the fan blade and the air duct of the indoor fan need to be cleaned, the water washing device generates water vapor, and the water vapor is spread to the fan blade and the air duct by the forward rotation of the indoor fan. At this time, the water vapor on the fan blade surface facing the water washing device is more, and the water vapor on the fan blade surface away from the water washing device is less. When the amount of water vapor meets the cleaning condition, the water washing device is controlled to refrigerate to convert the water vapor into condensate water, to adsorb the pollutants in the fan blade surface facing the water washing device and the air duct. At this time, the indoor fan is controlled to reverse to increase the condensate water on the fan blade surface away from the water washing device, to adsorb the pollutants on the fan blade surface. When the condensate water on both sides of the fan blade adsorbs the pollutants, the speed of the indoor fan rotation is adjusted to throw the condensate water containing the pollutants on the fan blade to the air duct, to realize the self-cleaning of the fan blade. When the cleaning of the pollutants of the fan blade is completed, the speed of the indoor fan rotation is adjusted and the direction of the indoor fan rotation is periodically adjusted, to realize the cleaning of the pollutants of the air duct. Since the hydrophobic membrane is arranged in the air duct, the condensate water containing the pollutants will enter the dust removal box through the pollution discharge hole under the action of gravity, to realize the self-cleaning of the fan blade and the air duct of the indoor fan.

[0058] The direction of the indoor fan rotation in step S236 is periodically adjusted, that is, the indoor fan is controlled to rotate forward for a certain time, then the indoor fan is controlled to rotate reversely for a certain time, then the indoor fan is controlled to rotate forward for a certain time, and so on. For example, the indoor fan is controlled to rotate forward for 1 min, then the indoor fan is controlled to rotate reversely for 1 min, then the indoor fan is controlled to rotate forward for 1 min, and so on, to periodically adjust the direction of the indoor fan rotation.

[0059] In combination with Figure 4 The embodiments of the present disclosure provide another method for air conditioner fan self-cleaning, which comprises the following steps:

[0060] S210, the air conditioner detects the amount of pollutants attached to the indoor fan.

[0061] S220, the air conditioner judges whether the amount of pollutants is greater than or equal to a set threshold value. If yes, step S241 is executed. If no, step S210 is returned.

[0062] S241, the air conditioner controls the atomizing piece to operate, to atomize the water into water vapor.

[0063] S232, the air conditioner controls the indoor fan to rotate forward, to spread the water vapor to the fan blade and the air duct of the indoor fan.

[0064] S243, in a case where the atomizing piece is controlled to run for a first set time t1, the air conditioner controls the refrigeration device to run, so as to condense the water vapor.

[0065] S234, the air conditioner controls the indoor fan to run reversely, so as to make the condensed water spread over the fan blades and the air duct of the indoor fan.

[0066] S235, in a case where the refrigeration device is controlled to run for a second set time t2, the air conditioner adjusts the speed of the indoor fan to run, so as to clean the fan blades of the indoor fan.

[0067] S236, in a case where the cleaning of the fan blades of the indoor fan reaches a third set time t3, the air conditioner adjusts the speed of the indoor fan to run, and periodically adjusts the direction of the indoor fan to run, so as to clean the air duct of the indoor fan.

[0068] By using the method for self-cleaning of the air conditioner fan provided by the embodiment of the present disclosure, the atomizing piece is controlled to run to generate water vapor, the water vapor is generated at a high speed, and the control process is easy to implement. The refrigeration device is controlled to run to convert the water vapor into condensed water, the speed of generating the condensed water is accelerated, and the control process is easy to implement.

[0069] In combination with Figure 5 the method for self-cleaning of the air conditioner fan provided by the embodiment of the present disclosure, another method for self-cleaning of the air conditioner fan is provided, which comprises the following steps:

[0070] S210, the air conditioner detects the amount of pollutants attached to the indoor fan.

[0071] S220, the air conditioner judges whether the amount of pollutants is greater than or equal to a set threshold value. If yes, step S231 is executed. If no, step S210 is returned.

[0072] S231, the air conditioner controls the water washing device to generate water vapor.

[0073] S232, the air conditioner controls the indoor fan to run forwardly, so as to make the water vapor spread over the fan blades and the air duct of the indoor fan.

[0074] S233, in a case where the water washing device is controlled to generate water vapor for a first set time t1, the air conditioner controls the water washing device to perform refrigeration, so as to condense the water vapor.

[0075] S234, the air conditioner controls the indoor fan to run reversely, so as to make the condensed water spread over the fan blades and the air duct of the indoor fan.

[0076] S235, in a case where the water washing device is controlled to perform refrigeration for a second set time t2, the air conditioner adjusts the speed of the indoor fan to run, so as to clean the fan blades of the indoor fan.

[0077] S236, in the case that the fan blade of the indoor fan reaches the third set time t3 in the cleaning chamber, the air conditioner adjusts the speed of the indoor fan rotation, and periodically adjusts the direction of the indoor fan rotation, to clean the air duct of the indoor fan.

[0078] S237, in the case that the air duct of the indoor fan reaches the fourth set time t4 in the cleaning chamber, the air conditioner closes the water washing device to stop generating water vapor and condensate.

[0079] S238, the air conditioner controls the forward rotation of the indoor fan, and adjusts the speed of the indoor fan rotation, to dry the fan blade and the air duct of the indoor fan.

[0080] S239, in the case that the water washing device is closed for the fifth set time t5, the air conditioner controls the indoor fan to stop running.

[0081] The method for air conditioner fan self-cleaning provided by the embodiment of the present disclosure can close the water washing device when the indoor fan self-cleaning is completed, to avoid the waste and damp caused by the generation of excessive water vapor and condensate. Controlling the forward rotation of the indoor fan and adjusting the speed of the indoor fan rotation can quickly dry the condensate of the fan blade and the air duct, so as to facilitate the user to use the air conditioner.

[0082] Optionally, in the first set time, the second set time and the fourth set time, the indoor fan rotates at a first preset rotating speed. In the third set time and the fifth set time, the indoor fan rotates at a second preset rotating speed. The first preset rotating speed is less than the second preset rotating speed. In this way, the low rotating speed of the indoor fan in the first set time facilitates the water vapor to spread to the fan blade and the air duct. The low rotating speed of the indoor fan in the second set time facilitates the condensate to spread to the fan blade and the air duct, to avoid the condensate not adsorbing the pollutants of the fan blade and being thrown to the air duct. The high rotating speed of the indoor fan in the third set time facilitates the condensate on the fan blade to be thrown to the air duct. The low rotating speed of the indoor fan in the fourth set time facilitates a large amount of condensate to be formed in the air duct to realize the overall cleaning of the air duct. The high rotating speed of the indoor fan in the fifth set time facilitates the drying of the fan blade and the air duct.

[0083] Specifically, the first preset rotating speed is in the range of [600, 800] rpm, and preferably, the first preset rotating speed is 650 rpm, 700 rpm or 750 rpm. The second preset rotating speed is in the range of [950, 1150] rpm, and preferably, the second preset rotating speed is 1000 rpm, 1050 rpm or 1100 rpm.

[0084] Optionally, in the case that the detected amount of the pollutant attached to the indoor fan is the amount of the pollutant attached to the fan blade or the amount of the pollutant attached to the air duct, the relationship between the first set time, the second set time, the third set time, the fourth set time and the fifth set time is t4 > t1 > t2 > t3 > t5. In this way, when detecting the single amount of the pollutant attached, the time for cleaning the fan blade and the air duct is balanced, and the pollutants can be cleaned in a large range. The first set time is longer than the second set time, and the water vapor can spread to the fan blade and the air duct, and enough condensate water can be generated to adsorb the pollutants. The fourth set time is the longest, which can comprehensively clean the air duct and reduce the residual amount of the pollutants. The third set time is lower than the second set time, and the indoor fan is sufficient to use high speed to throw the sewage to the air duct to clean the fan blade, thereby saving the time required for the self-cleaning process of the indoor fan. The fifth set time is the shortest, and the indoor fan is sufficient to use high speed to dry the fan blade and the air duct, thereby saving the time required for the self-cleaning process of the indoor fan.

[0085] For example, the first set time t1 is 6 min, the second set time t2 is 5 min, the third set time t3 is 3 min, the fourth set time t4 is 8 min, and the fifth set time t5 is 2 min.

[0086] Optionally, in the case that the detected amount of the pollutant attached to the indoor fan is the amount of the pollutant attached to the fan blade and the amount of the pollutant attached to the air duct, the air conditioner determines the difference between the amount of the pollutant attached to the fan blade and the amount of the pollutant attached to the air duct. In the case that the difference is positive and higher than a difference threshold value, the air conditioner increases the third set time by a first time value. In the case that the difference is positive and lower than the difference threshold value, the air conditioner increases the third set time by a second time value. In the case that the difference is negative and higher than the difference threshold value, the air conditioner increases the fourth set time by the first time value. In the case that the difference is negative and lower than the difference threshold value, the air conditioner increases the fourth set time by the second time value. The first time value is greater than the second time value. In this way, the time for the self-cleaning of the indoor fan is adjusted according to the amount of the pollutant attached to the fan blade and the air duct, which can improve the effect of the self-cleaning and reduce the pollutants of the fan blade and the air duct. For example, the first time value is 3 min, and the second time value is 1 min.

[0087] The value of the amount of the pollutant attached and the difference threshold value can be determined according to the corresponding relationship of different detection methods. The amount of the pollutant attached to 0 indicates that the fan blade and / or the air duct has no pollutants, and the amount of the pollutant attached to 100 indicates that the fan blade and / or the air duct has been completely blocked by the pollutants.

[0088] In combination Figure 6As shown, the apparatus for air conditioner fan self-cleaning provided by the embodiments of the present disclosure includes a processor 41 and a memory 42. Optionally, the apparatus can further include a communication interface 43 and a bus 44.
