[0025] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings.

[0026] It should be noted that the terms "first", "second", etc. in the specification and claims of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0027] The acquisition, storage, use, and processing of data in the technical solution disclosed in this disclosure are in compliance with the relevant laws and regulations.

[0028] Figure 1 is a flow chart showing a self-cleaning method for an air conditioner according to an exemplary embodiment. Figure 1 As shown, the self-cleaning method of the air conditioner according to the embodiment of the present disclosure includes the following steps.

[0029] S101, performing multiple rounds of self-cleaning on the air conditioner. During each round of self-cleaning, in response to the air conditioner entering a condensation stage, the fresh air device is turned on and the fresh air is humidified by the humidification component.

[0030] It should be noted that the execution subject of the self-cleaning method of the air conditioner in the embodiment of the present disclosure is an electronic device, such as a mobile phone, a notebook, a desktop computer, a vehicle-mounted terminal, a smart home appliance, a wearable device, etc. Among them, the wearable device may include a wrist-worn device (such as a smart watch, a smart bracelet), a head-worn device, a foot-worn device, etc. The self-cleaning method of the air conditioner in the embodiment of the present disclosure can be executed by the self-cleaning device of the air conditioner in the embodiment of the present disclosure, and the self-cleaning device of the air conditioner in the embodiment of the present disclosure can be configured in any electronic device to execute the self-cleaning method of the air conditioner in the embodiment of the present disclosure.

[0031] In the embodiment of the present disclosure, the air conditioner includes a fresh air device, the fresh air device includes a humidification component, and the indoor heat exchanger is located in the main air duct. There is no excessive limitation on the humidification component, for example, it may include an ultrasonic humidifier, an evaporative humidifier, a steam humidifier, etc. The main air duct refers to the main pipeline in the air conditioner for transmitting air.

[0032] It is understandable that after the fresh air device is turned on, outdoor air (i.e., fresh air) can enter the fresh air duct of the fresh air device through the fresh air inlet, and the fresh air is humidified by the humidification component. The fresh air duct runs through the fresh air inlet and the fresh air outlet. For example, Figure 3 , 4 As shown, the fresh air inlet and the rear air outlet of the fresh air device are arranged on the rear housing of the air conditioner at intervals. Figure 3 , 4 The arrows in the figure indicate the direction of air flow.

[0033] In the embodiments of the present disclosure, the air conditioner can be subjected to multiple rounds of self-cleaning, and each round of self-cleaning process includes a condensation stage. The total number of rounds of self-cleaning for the air conditioner is not limited too much, for example, it can be 3 rounds. The working stages included in different rounds of self-cleaning processes may be the same or different, and the running time of the same working stage in different rounds of self-cleaning processes may be the same or different.

[0034] In one embodiment, at least two rounds of self-cleaning processes include different working stages. For example, if the total number of self-cleaning rounds of the air conditioner is 3 rounds, the working stages included in the first and second rounds of self-cleaning processes are the condensation stage and the frosting stage, but not the defrosting stage, and the working stages included in the third round of self-cleaning process are the condensation stage, the frosting stage, and the defrosting stage.

[0035] In one embodiment, the running time of the same working stage in at least two rounds of self-cleaning process is different. For example, the running time of the frosting stage in the first round of self-cleaning process is 5 to 15 minutes, and the running time of the frosting stage in the second round of self-cleaning process is 10 to 20 minutes. In some examples, the running time of the frosting stage in the first round of self-cleaning process is 10 minutes, and the running time of the frosting stage in the second round of self-cleaning process is 15 minutes.

[0036] In one embodiment, before the fresh air is humidified by the humidifying component, the air humidity in the fresh air duct of the fresh air device is detected, and the humidifying component is turned on in response to the air humidity being less than the set humidity. Thus, the humidifying component can be turned on only when the air humidity in the fresh air duct is low, avoiding turning on the humidifying component when the air humidity in the fresh air duct is high, which helps save energy consumption.

[0037] In some examples, the method further includes continuing to close the humidification component in response to the air humidity being greater than or equal to the set humidity. Thus, when the air humidity in the fresh air duct is high, the humidification component can be continued to be closed, which helps to save energy consumption.

[0038] It should be noted that there are no excessive restrictions on the set humidity, for example, it can be 60%.

[0039] In one embodiment, the method further includes, in response to the air conditioner entering the condensation stage, turning on the indoor fan in the main air duct (hereinafter referred to as the indoor fan) and the outdoor fan of the air conditioner, adjusting the speed of the indoor fan to a second set speed, adjusting the speed of the fresh air fan of the fresh air device to a third set speed, and adjusting the speed of the outdoor fan to a fourth set speed. The second set speed is the speed corresponding to the low wind gear of the indoor fan, the third set speed is the speed corresponding to the high wind gear of the fresh air fan, and the fourth set speed is the speed corresponding to the high wind gear of the outdoor fan. For example, the second set speed is 600r / min (revolutions / minute), the third set speed is 2000r / min, and the fourth set speed is 800r / min.

[0040] In one embodiment, the method further includes, in response to the air conditioner entering the condensation stage, turning on the compressor of the air conditioner, and controlling the operating frequency of the compressor to be within a set frequency range. It should be noted that the set frequency range is not too limited, for example, it can be 15 to 80 Hz (Hertz). For example, the operating frequency of the compressor can be adjusted to 70 Hz.

[0041] In one embodiment, the method further includes controlling the opening of the expansion valve to be within a set opening range in response to the air conditioner entering a condensation stage. It should be noted that the set opening range is not excessively limited. For example, the opening of the expansion valve can be adjusted by adjusting the stroke of a drive component (such as a stepper motor). At this time, the opening of the expansion valve can be characterized by the stroke of the drive component. For example, the opening range is set to 100 to 400P, where P is the stroke unit of the drive component. For example, the opening of the expansion valve can be adjusted to 350P.

[0042] It should be noted that there is no excessive limitation on the operation duration of the condensation stage, for example, it can be 5 to 15 minutes.

[0043] S102, determining a fresh air outlet corresponding to a fresh air outlet mode of a fresh air device as a first target outlet.

[0044] It should be noted that there is a corresponding relationship between the fresh air outlet mode and the fresh air outlet, for example, the fresh air outlet mode corresponds to the fresh air outlet one by one. Different fresh air outlet modes correspond to different fresh air outlets. The first target outlet refers to the actual outlet of the fresh air device.

[0045] For example, the fresh air outlet includes a first air outlet, and the fresh air outlet corresponding to the fresh air outlet mode of the fresh air device is determined as the first target air outlet, including responding to the fresh air outlet mode to discharge humidified fresh air from the first air outlet, and taking the first air outlet as the first target air outlet.

[0046] For example, the fresh air outlet includes a second air outlet, and the fresh air outlet corresponding to the fresh air outlet mode of the fresh air device is determined as the first target air outlet, including responding to the fresh air outlet mode to discharge humidified fresh air from the second air outlet, and taking the second air outlet as the first target air outlet.

[0047] S103, controlling the humidified fresh air discharged from the first target air outlet to enter the main air duct, and allowing the humidified fresh air to flow through the indoor heat exchanger.

[0048] It is understandable that the air conditioner is in cooling mode during the condensation stage, and the temperature of the outer surface of the indoor heat exchanger (including the outer surface of the refrigerant pipeline of the indoor heat exchanger) is relatively low. The humidified fresh air flows through the indoor heat exchanger, which increases the air humidity around the indoor heat exchanger. Therefore, when the air around the indoor heat exchanger contacts the outer surface of the indoor heat exchanger, the water vapor therein is more likely to be cooled and liquefied, which will produce more condensed water on the outer surface of the indoor heat exchanger, helping to improve the self-cleaning effect of the indoor heat exchanger.

[0049] It is understandable that the air in the main air duct includes the humidified fresh air discharged from the first target air outlet, and also includes indoor air. The relevant content of the indoor air entering the main air duct can refer to the self-cleaning method of any air conditioner in the relevant technology, and no excessive restrictions are made here. The air flowing through the indoor heat exchanger can be discharged from the air outlet of the main air duct. In the embodiment of the present disclosure, the air outlet of the main air duct refers to the actual air outlet of the main air duct, which may be different from the main air outlet of the air conditioner.

[0050] In one embodiment, the humidified fresh air discharged from the first target air outlet is controlled to enter the main air duct, and the humidified fresh air is made to flow through the indoor heat exchanger, including adjusting the air flow direction in the main air duct based on the fresh air outlet mode of the fresh air device, so as to control the humidified fresh air discharged from the first target air outlet to enter the main air duct, and the humidified fresh air is made to flow through the indoor heat exchanger. Thus, the air flow direction in the main air duct can be adjusted in consideration of the fresh air outlet mode of the fresh air device, so as to form a negative pressure at the air inlet of the main air duct, so that the humidified fresh air discharged from the first target air outlet enters the main air duct through the air inlet of the main air duct, and the humidified fresh air is blown from the air inlet of the main air duct to the indoor heat exchanger according to the air flow direction in the main air duct.

[0051] It is understandable that when negative pressure is formed at the air inlet of the main air duct, the indoor air will also enter the main air duct through the air inlet of the main air duct. In the process of controlling the humidified fresh air to flow through the indoor heat exchanger, the indoor air will also flow through the indoor heat exchanger along with the humidified fresh air.

[0052] In the disclosed embodiment, the air inlet of the main air duct refers to the actual air inlet of the main air duct, which may be different from the main air inlet of the air conditioner. The relevant content of the air inlet of the main air duct can be found in the following embodiments and will not be repeated here.

[0053] In some examples, based on the fresh air outlet mode of the fresh air device, the air flow direction in the main air duct is adjusted, including obtaining a mapping relationship between the candidate outlet mode of the fresh air device and the candidate air flow direction in the main air duct, obtaining a candidate air flow direction having a mapping relationship with the fresh air outlet mode as a target air flow direction, and adjusting the air flow direction in the main air duct to the target air flow direction. It is understandable that different candidate outlet modes may map different candidate air flow directions.

[0054] It should be noted that there are no excessive restrictions on the way to adjust the air flow direction in the main air duct. For example, the direction of the indoor fan in the main air duct can be adjusted, and / or the air guide parameters of the air guide device arranged in the main air duct can be adjusted to adjust the air flow direction in the main air duct. The air guide device can include an air guide plate, an air guide strip, etc., and the air guide parameters can include an opening angle, an opening size, a position, an inclination angle, etc.

[0055] In one embodiment, the air conditioner also includes a first air duct, the first air duct runs through the first target air outlet and the third target air outlet, the main air duct runs through the third target air outlet, and the humidified fresh air discharged from the first target air outlet is controlled to enter the main air duct, including controlling the humidified fresh air to enter the first air duct through the first target air outlet, controlling the humidified fresh air to blow from the first target air outlet to the third target air outlet, and controlling the humidified fresh air to enter the main air duct through the third target air outlet.

[0056] S104, during the condensation stage of at least one round of self-cleaning, the fresh air outlet mode is switched.

[0057] It can be understood that during the condensation stage of at least one round of self-cleaning process, the fresh air outlet mode is switched, so that the fresh air outlet modes of at least two rounds of self-cleaning processes of the air conditioner are different during the condensation stage. Compared with only using one fresh air outlet mode for condensation during multiple rounds of self-cleaning processes, this scheme can use multiple fresh air outlet modes for condensation during multiple rounds of self-cleaning processes. The humidified fresh air can enter the main air duct from different fresh air outlets, which helps to evenly produce condensed water on the outer surface of the indoor heat exchanger, thereby improving the self-cleaning effect of the indoor heat exchanger.

[0058] For example, the fresh air outlet mode of the air conditioner is consistent in multiple working stages during the same round of self-cleaning process.

[0059] In one embodiment, switching the fresh air outlet mode includes switching the fresh air outlet mode in response to the air conditioner satisfying a set switching condition. Thus, the fresh air outlet mode can be switched when the air conditioner satisfies the set switching condition.

[0060] It should be noted that there are no excessive restrictions on setting the switching conditions.

[0061] In some examples, in response to the air conditioner satisfying the set switching condition, the fresh air outlet mode is switched, including switching the fresh air outlet mode in response to the air conditioner entering the condensation stage. Thus, the fresh air outlet mode can be switched every time the air conditioner enters the condensation stage.

[0062] For example, the fresh air outlet includes a first air outlet and a second air outlet. If the total number of self-cleaning rounds of the air conditioner is 4 rounds, in the first round of self-cleaning, in response to the air conditioner entering the condensation stage, the fresh air outlet mode is switched to discharge humidified fresh air from the first air outlet; in the second round of self-cleaning, in response to the air conditioner entering the condensation stage, the fresh air outlet mode is switched to discharge humidified fresh air from the second air outlet; in the third round of self-cleaning, in response to the air conditioner entering the condensation stage, the fresh air outlet mode is switched to discharge humidified fresh air from the first air outlet; and in the fourth round of self-cleaning, in response to the air conditioner entering the condensation stage, the fresh air outlet mode is switched to discharge humidified fresh air from the second air outlet.

[0063] In some examples, in response to the air conditioner satisfying a set switching condition, switching the fresh air outlet mode includes obtaining a first cumulative number of rounds of continuous self-cleaning of the air conditioner in the same fresh air outlet mode, and switching the fresh air outlet mode in response to the first cumulative number of rounds reaching a first set number of rounds. Thus, when the first cumulative number of rounds of continuous self-cleaning of the air conditioner in the same fresh air outlet mode reaches the first set number of rounds, the fresh air outlet mode can be switched.

[0064] It should be noted that there is no excessive limitation on the first set number of rounds, for example, it can be 2 rounds.

[0065] In some examples, the method further includes maintaining the fresh air outlet mode during the current round of self-cleaning of the air conditioner in response to the first cumulative number of rounds not reaching the first set number of rounds. Thus, when the first cumulative number of rounds in which the air conditioner continuously performs self-cleaning in the same fresh air outlet mode does not reach the first set number of rounds, the fresh air outlet mode can be maintained during the current round of self-cleaning of the air conditioner, that is, the fresh air outlet mode is not switched during the current round of self-cleaning.

[0066] For example, the fresh air outlet includes a first air outlet and a second air outlet, if the total number of rounds of self-cleaning of the air conditioner is 4 rounds, and the first set number of rounds is 2 rounds.

[0067] During the first round of self-cleaning, in response to the air conditioner entering the condensation stage, the fresh air outlet mode is switched to discharge humidified fresh air from the first air outlet.

[0068] During the second round of self-cleaning, in response to the air conditioner entering the condensation stage, and the first cumulative round number corresponding to the humidified fresh air discharged from the first air outlet is 1, which is less than the first set round number, the fresh air outlet mode is maintained during the second round of self-cleaning, that is, the fresh air outlet mode during the second round of self-cleaning is still the humidified fresh air discharged from the first air outlet.

[0069] During the third round of self-cleaning, in response to the air conditioner entering the condensation stage, and the first cumulative number of rounds corresponding to the humidified fresh air discharged from the first air outlet is 2, reaching the first set number of rounds, the fresh air outlet mode is switched to discharge the humidified fresh air from the second air outlet.

[0070] During the 4th round of self-cleaning, in response to the air conditioner entering the condensation stage and the first cumulative round number corresponding to the humidified fresh air discharged from the second air outlet is 1, which is less than the first set round number, the fresh air outlet mode is maintained during the 4th round of self-cleaning, that is, the fresh air outlet mode during the 4th round of self-cleaning is still the humidified fresh air discharged from the second air outlet.

[0071] The self-cleaning method of the air conditioner provided in the embodiment of the present disclosure performs multiple rounds of self-cleaning on the air conditioner. During each round of self-cleaning, in response to the air conditioner entering the condensation stage, the fresh air device is turned on, and the fresh air is humidified by the humidification component. The fresh air outlet corresponding to the fresh air outlet mode of the fresh air device is determined as the first target air outlet, and the humidified fresh air discharged from the first target air outlet is controlled to enter the main air duct, and the humidified fresh air is made to flow through the indoor heat exchanger. During the condensation stage of at least one round of self-cleaning, the fresh air outlet mode is switched. Therefore, during the condensation stage, the fresh air can be humidified by the humidification component, and the humidified fresh air discharged from the first target air outlet is controlled to enter the main air duct, and the humidified fresh air is made to flow through the indoor heat exchanger, which can increase the air humidity around the indoor heat exchanger, thereby generating more condensed water on the outer surface of the indoor heat exchanger. In addition, during the condensation stage of at least one round of self-cleaning process, the fresh air outlet mode is switched, so that a variety of fresh air outlet modes can be used for condensation during multiple rounds of self-cleaning processes. The humidified fresh air can enter the main air duct from different fresh air outlets, which helps to evenly generate condensed water on the outer surface of the indoor heat exchanger, and the air conditioner can be subjected to multiple rounds of self-cleaning, which helps to improve the self-cleaning effect of the indoor heat exchanger.

[0072] On the basis of any of the above embodiments, the method further includes obtaining a second cumulative number of self-cleaning rounds of the air conditioner, and in response to the second cumulative number of rounds not reaching the second set number of rounds, determining that the current round of self-cleaning process of the air conditioner does not include a defrosting stage, and in response to the second cumulative number of rounds reaching the second set number of rounds, determining that the current round of self-cleaning process includes a defrosting stage. Thus, when the second cumulative number of self-cleaning rounds of the air conditioner does not reach the second set number of rounds, it can be determined that the current round of self-cleaning process does not include a defrosting stage, and when the second cumulative number of rounds reaches the second set number of rounds, it can be determined that the current round of self-cleaning process includes a defrosting stage, that is, defrosting is performed in the last few rounds of self-cleaning processes of the air conditioner, which helps to save energy consumption.

[0073] It should be noted that the second cumulative number of rounds refers to the cumulative number of self-cleaning rounds that the air conditioner has completed, and is not included in the current round of self-cleaning process. There is no excessive limitation on the second set number of rounds. For example, if the total number of self-cleaning rounds of the air conditioner is N, the second set number of rounds is N-1, that is, defrosting is performed only in the last round of self-cleaning process of the air conditioner.

[0074] In some examples, the method further includes obtaining a third set number of self-cleaning cycles performed by the air conditioner including a defrosting stage, obtaining a difference between the total number of self-cleaning cycles performed by the air conditioner and the third set number of self-cleaning cycles, and obtaining a second set number of self-cleaning cycles based on the difference. Thus, the difference between the total number of self-cleaning cycles performed by the air conditioner and the third set number of self-cleaning cycles can be comprehensively considered, and the second set number of self-cleaning cycles can be obtained based on the difference.

[0075] It should be noted that there are no excessive restrictions on the third set number of rounds, for example, it can be 1, 2, etc. Obtaining the second set number of rounds based on the difference includes using the difference as the second set number of rounds.

[0076] Figure 2 is a flow chart showing a self-cleaning method for an air conditioner according to another exemplary embodiment. Figure 2 As shown, the self-cleaning method of the air conditioner according to the embodiment of the present disclosure includes the following steps.

[0077] S201, performing multiple rounds of self-cleaning on the air conditioner. During each round of self-cleaning, in response to the air conditioner entering a condensation stage, the fresh air device is turned on and the fresh air is humidified by the humidification component.

[0078] S202, determining a fresh air outlet corresponding to a fresh air outlet mode of the fresh air device as a first target outlet.

[0079] For the relevant contents of steps S201 - S202 , please refer to the above embodiment and will not be described again here.

[0080] S203, based on the fresh air outlet mode, the air inlet of the main air duct is switched to adjust the air flow direction in the main air duct.

[0081] It can be understood that the air flow direction in the main air duct is from the air inlet of the main air duct to the indoor heat exchanger, and then from the indoor heat exchanger to the air outlet of the main air duct. The air inlet of the main air duct is switched to adjust the air flow direction in the main air duct, thereby forming a negative pressure at the air inlet of the main air duct, so that the humidified fresh air discharged from the first target air outlet enters the main air duct through the air inlet of the main air duct, and the humidified fresh air is blown from the air inlet of the main air duct to the indoor heat exchanger according to the air flow direction in the main air duct.

[0082] In one embodiment, the fresh air outlet and the candidate air outlets that are connected to the main air duct are arranged at intervals on the same side of the air conditioner housing. It is understandable that there are multiple candidate air outlets that are connected to the main air duct.

[0083] Based on the fresh air outlet mode of the fresh air device, the air inlet of the main air duct is switched, including obtaining a candidate air outlet located on the same side of the shell as the first target air outlet as the second target air outlet, and switching the air inlet of the main air duct to the second target air outlet to control the humidified fresh air discharged from the first target air outlet to enter the main air duct through the second target air outlet, and make the humidified fresh air blow from the second target air outlet toward the indoor heat exchanger.

[0084] It can be understood that when the air inlet of the main air duct is switched to the second target air outlet, the air flow direction in the main air duct can be adjusted to blow from the second target air outlet to the indoor heat exchanger, thereby forming a negative pressure at the second target air outlet, so that the humidified fresh air discharged from the first target air outlet enters the main air duct through the second target air outlet, and the humidified fresh air is blown from the second target air outlet to the indoor heat exchanger according to the air flow direction in the main air duct. Compared with the outer surface of the indoor heat exchanger far from the second target air outlet, the outer surface of the indoor heat exchanger close to the second target air outlet has more contact with the humidified fresh air, which will produce more condensed water on the outer surface of the indoor heat exchanger close to the second target air outlet, and especially enhance the self-cleaning effect of the outer surface of the indoor heat exchanger close to the second target air outlet.

[0087] The self-cleaning method of the air conditioner provided in the embodiment of the present disclosure can take into account the fresh air outlet mode and switch the air inlet of the main air duct to adjust the air flow direction in the main air duct, thereby forming a negative pressure at the air inlet of the main air duct, so that the humidified fresh air discharged from the first target air outlet enters the main air duct through the air inlet of the main air duct, and the humidified fresh air is blown from the air inlet of the main air duct to the indoor heat exchanger according to the air flow direction in the main air duct.

[0088] On the basis of any of the above embodiments, the fresh air outlet includes a first air outlet, and the first air outlet is spaced apart from a candidate first air outlet that is connected to the main air duct and is arranged on a first side shell of the air conditioner.

[0091] For example, Figure 3 , 4 As shown, the main air duct runs through the main air outlet of the air conditioner, and the front air outlet of the fresh air device is arranged on the front shell of the air conditioner at intervals from the main air outlet. The indoor heat exchanger is located on one side of the main air duct close to the main air inlet of the air conditioner, that is, the indoor heat exchanger is close to the rear shell of the air conditioner.

[0096] S503, in response to the fresh air outlet mode being to discharge humidified fresh air from the first air outlet, the air inlet of the main air duct is switched to the candidate first air outlet to control the humidified fresh air discharged from the first air outlet to enter the main air duct through the candidate first air outlet, and make the humidified fresh air blow from the candidate first air outlet toward the indoor heat exchanger.

[0097] It should be noted that, in this embodiment, the first target air outlet is the first air outlet.

[0098] It can be understood that when the air inlet of the main air duct is switched to the candidate first air outlet, the air flow direction in the main air duct can be adjusted to blow from the candidate first air outlet to the indoor heat exchanger, thereby forming a negative pressure at the candidate first air outlet, so that the humidified fresh air discharged from the first air outlet enters the main air duct through the candidate first air outlet, and the humidified fresh air is blown from the candidate first air outlet to the indoor heat exchanger according to the air flow direction in the main air duct. Compared with the outer surface of the indoor heat exchanger far from the candidate first air outlet, the outer surface of the indoor heat exchanger close to the candidate first air outlet has more contact with the humidified fresh air, which will produce more condensation water on the outer surface of the indoor heat exchanger close to the candidate first air outlet, and especially enhance the self-cleaning effect of the outer surface of the indoor heat exchanger close to the candidate first air outlet.

[0100] It can be understood that when the air inlet of the main air duct is switched to the main air outlet, the air flow direction in the main air duct can be adjusted to blow from the main air outlet to the indoor heat exchanger, thereby forming a negative pressure at the main air outlet, so that the humidified fresh air discharged from the front air outlet enters the main air duct through the main air outlet, and the humidified fresh air is blown from the main air outlet to the indoor heat exchanger according to the air flow direction in the main air duct. Compared with the outer surface of the indoor heat exchanger far from the main air outlet, the outer surface of the indoor heat exchanger close to the main air outlet has more contact with the humidified fresh air, which will produce more condensed water on the outer surface of the indoor heat exchanger close to the main air outlet, and especially enhance the self-cleaning effect of the outer surface of the indoor heat exchanger close to the main air outlet.

[0113] S603, in response to the fresh air outlet mode being to discharge humidified fresh air from the second air outlet, the air inlet of the main air duct is switched to the candidate second air outlet to control the humidified fresh air discharged from the second air outlet to enter the main air duct through the candidate second air outlet, and make the humidified fresh air blow from the candidate second air outlet toward the indoor heat exchanger.

[0114] It should be noted that, in this embodiment, the first target air outlet is the second air outlet.

[0115] It can be understood that when the air inlet of the main air duct is switched to the candidate second air outlet, the air flow direction in the main air duct can be adjusted to blow from the candidate second air outlet to the indoor heat exchanger, thereby forming a negative pressure at the candidate second air outlet, so that the humidified fresh air discharged from the second air outlet enters the main air duct through the candidate second air outlet, and the humidified fresh air is blown from the candidate second air outlet to the indoor heat exchanger according to the air flow direction in the main air duct. Compared with the outer surface of the indoor heat exchanger far from the candidate second air outlet, the outer surface of the indoor heat exchanger close to the candidate second air outlet has more contact with the humidified fresh air, which will produce more condensation water on the outer surface of the indoor heat exchanger close to the candidate second air outlet, and especially enhance the self-cleaning effect of the outer surface of the indoor heat exchanger close to the candidate second air outlet.

[0116] For example, Figure 4 As shown, based on the fresh air outlet mode of the fresh air device, the air inlet of the main air duct is switched, including switching the air inlet of the main air duct to the main air inlet in response to the fresh air outlet mode being to discharge humidified fresh air from the rear air outlet, so as to control the humidified fresh air discharged from the rear air outlet to enter the main air duct through the main air inlet, and make the humidified fresh air blow from the main air inlet toward the indoor heat exchanger.

[0117] It can be understood that when the air inlet of the main air duct is switched to the main air inlet, the air flow direction in the main air duct can be adjusted to blow from the main air inlet to the indoor heat exchanger, thereby forming a negative pressure at the main air inlet, so that the humidified fresh air discharged from the rear air outlet enters the main air duct through the main air inlet, and the humidified fresh air is blown from the main air inlet to the indoor heat exchanger according to the air flow direction in the main air duct. Compared with the outer surface of the indoor heat exchanger far from the main air inlet, the outer surface of the indoor heat exchanger close to the main air inlet has more contact with the humidified fresh air, which will produce more condensed water on the outer surface of the indoor heat exchanger close to the main air inlet, and especially enhance the self-cleaning effect of the outer surface of the indoor heat exchanger close to the main air inlet.

[0118] like Figure 4 As shown, at this time, the air inlet of the main air duct is the main air inlet, and the air outlet of the main air duct is the main air outlet.

It is understandable that the candidate turning directions mapped to different candidate air flow directions may be different.

[0130] In one embodiment, the fresh air outlet includes a first air outlet, the first air outlet is arranged on the first side housing of the air conditioner at intervals from a candidate first air outlet that is connected to the main air duct, and the candidate first air outlet is connected to the air outlet of the indoor fan. It should be noted that the air outlet of the indoor fan refers to the actual air outlet of the indoor fan when the indoor fan is in normal operation.

[0131] Based on the fresh air outlet mode, the direction of the indoor fan in the main air duct is adjusted, including adjusting the direction of the indoor fan to reverse in response to the fresh air outlet mode being to discharge humidified fresh air from the first air outlet, so as to adjust the air flow direction in the main air duct to blow from the candidate first air outlet to the indoor heat exchanger. It can be understood that when the direction of the indoor fan is adjusted to reverse, air is sucked from the air outlet of the indoor fan, that is, the indoor fan can suck air from the candidate first air outlet that is connected to the air outlet of the indoor fan, thereby forming a negative pressure at the candidate first air outlet, so as to adjust the air flow direction in the main air duct to blow from the candidate first air outlet to the indoor heat exchanger.

[0132] For example, Figure 3 , 4 As shown, the main air duct runs through the main air outlet of the air conditioner, the front air outlet of the fresh air device is arranged on the front shell of the air conditioner with an interval between the main air outlet, and the main air outlet is connected to the air outlet of the indoor fan (not shown in the figure).

It can be understood that when the direction of the indoor fan is adjusted to reverse, air is sucked from the air outlet of the indoor fan, that is, the indoor fan can suck air from the main air outlet that is connected to the air outlet of the indoor fan, thereby forming a negative pressure at the main air outlet, so as to adjust the air flow direction in the main air duct to blow from the main air outlet to the indoor heat exchanger.

[0134] In one embodiment, the fresh air outlet includes a second air outlet, the second air outlet is arranged on the second side housing of the air conditioner at intervals with a candidate second air outlet that is connected to the main air duct, and the candidate second air outlet is connected to the air inlet of the indoor fan.

It can be understood that when the direction of the indoor fan is adjusted to forward rotation, air is sucked from the air inlet of the indoor fan, that is, the indoor fan can suck air from the candidate second air outlet that is connected to the air inlet of the indoor fan, thereby forming a negative pressure at the candidate second air outlet, so as to adjust the air flow direction in the main air duct to blow from the candidate second air outlet to the indoor heat exchanger.

[0136] For example, Figure 3 , 4 As shown, the main air duct runs through the main air inlet of the air conditioner, the rear air outlet of the fresh air device is arranged on the rear shell of the air conditioner with an interval between the main air inlet, and the main air inlet is connected to the air inlet of the indoor fan (not shown in the figure).

It can be understood that when the direction of the indoor fan is adjusted to forward rotation, air is sucked from the air inlet of the indoor fan, that is, the indoor fan can suck air from the main air inlet that is connected to the air inlet of the indoor fan, thereby forming a negative pressure at the main air inlet, so as to adjust the air flow direction in the main air duct to blow from the main air inlet to the indoor heat exchanger.

[0138] S704, during the condensation stage of at least one round of self-cleaning, the fresh air outlet mode is switched.

[0139] For the relevant contents of step S704, please refer to the above embodiment, which will not be repeated here.

[0140] The self-cleaning method of the air conditioner provided in the embodiment of the present disclosure can adjust the direction of the indoor fan in the main air duct in consideration of the fresh air outlet mode, so as to adjust the air flow direction in the main air duct.

[0145] S803, adjusting the air guiding parameters of the air guiding device arranged at the first target air outlet to control the humidified fresh air discharged from the first target air outlet to enter the main air duct.

[0146] In this embodiment, the air conditioner further comprises an air guide device arranged at the fresh air outlet, wherein the air guide device may comprise an air guide plate, an air guide strip, etc., and the air guide parameters may comprise an opening angle, an opening size, a position, and an inclination angle.

[0147] In one embodiment, adjusting the air guiding parameters of the air guiding device arranged at the first target air outlet includes adjusting the opening angle of the air guiding device arranged at the first target air outlet to within a set angle range.

[0148] In one embodiment, adjusting the air guiding parameters of the air guiding device arranged at the first target air outlet includes moving the position of the air guiding device arranged at the first target air outlet to a set position.

[0149] For example, Figure 3 As shown, in response to the fresh air outlet mode being to discharge fresh air from the front air outlet, the front air outlet is determined to be the first target air outlet, and the air guiding parameters of the air guiding device (not shown in the figure) arranged at the front air outlet are adjusted to control the humidified fresh air discharged from the front air outlet to enter the main air duct.

[0150] For example, Figure 4 As shown, in response to the fresh air outlet mode being to discharge fresh air from the rear air outlet, the rear air outlet is determined to be the first target air outlet, and the air guiding parameters of the air guiding device (not shown in the figure) arranged at the rear air outlet are adjusted to control the humidified fresh air discharged from the rear air outlet to enter the main air duct.

[0151] S804, controlling the humidified fresh air to flow through the indoor heat exchanger.

[0152] S805, during the condensation stage of at least one round of self-cleaning, the fresh air outlet mode is switched.

[0153] For the relevant contents of steps S804-S805, please refer to the above embodiment and will not be repeated here.

[0154] The self-cleaning method of the air conditioner provided by the embodiment of the present disclosure adjusts the air guiding parameters of the air guiding device arranged at the first target air outlet to control the humidified fresh air discharged from the first target air outlet to enter the main air duct. Thus, the first target air outlet can be determined in consideration of the fresh air outlet mode, and the air guiding parameters of the air guiding device arranged at the first target air outlet can be adjusted to control the humidified fresh air discharged from the first target air outlet to enter the main air duct.

[0155] Based on any of the above embodiments, the method further includes adjusting the fresh air flow direction in the fresh air duct of the fresh air device based on the fresh air outlet mode of the fresh air device to control the humidified fresh air to be discharged from the first target air outlet. Thus, considering the fresh air outlet mode, the fresh air flow direction in the fresh air duct can be adjusted to control the humidified fresh air to be discharged from the first target air outlet.

[0156] For example, Figure 3 As shown, based on the fresh air outlet mode of the fresh air device, the flow direction of fresh air in the fresh air duct of the fresh air device is adjusted, including adjusting the flow direction of fresh air in the fresh air duct to blow from the fresh air inlet to the front air outlet in response to the fresh air outlet mode being to discharge humidified fresh air from the front air outlet, so as to control the humidified fresh air to be discharged from the front air outlet.

[0157] For example, Figure 4 As shown, based on the fresh air outlet mode of the fresh air device, the flow direction of fresh air in the fresh air duct of the fresh air device is adjusted, including adjusting the flow direction of fresh air in the fresh air duct to blow from the fresh air inlet to the rear air outlet in response to the fresh air outlet mode being to discharge humidified fresh air from the rear air outlet, so as to control the humidified fresh air to be discharged from the rear air outlet.

[0158] In some examples, based on the fresh air outlet mode of the fresh air device, the fresh air flow direction in the fresh air duct of the fresh air device is adjusted, including adjusting the operating parameters of the air outlet switching motor of the fresh air device based on the fresh air outlet mode to adjust the fresh air flow direction in the fresh air duct of the fresh air device.

[0159] Fig. 9 is a flow chart showing a self-cleaning method for an air conditioner according to another exemplary embodiment. Fig. 9 As shown, the self-cleaning method of the air conditioner according to the embodiment of the present disclosure includes the following steps.

[0160] S901, in response to the air conditioner entering a frosting stage, turning off the fresh air device.

[0161] In one embodiment, the method further includes, in response to the air conditioner entering the frosting stage, turning off the indoor fan, adjusting the speed of the outdoor fan to a fourth set speed, and controlling the opening of the expansion valve to be within the set opening range. It should be noted that the relevant contents of the fourth set speed and the set opening range can be referred to the above embodiment, and will not be repeated here.

[0162] It should be noted that there is no excessive limitation on the running time of the frosting stage, for example, it can be 10 to 20 minutes.

[0163] S902: Obtain a first difference between the inner pipe temperature of the air conditioner and a first set temperature.

[0164] It should be noted that the inner tube temperature of the air conditioner refers to the tube wall temperature of the indoor heat exchanger. There are no excessive restrictions on the first set temperature. For example, it may include the target inner tube temperature of the air conditioner in the frosting stage. For example, the first set temperature may be -5 to -15°C (Celsius).

[0165] S903: Adjust the operating frequency of the compressor of the air conditioner based on the first difference.

[0166] In one embodiment, based on the first difference, the operating frequency of the compressor of the air conditioner is adjusted, including increasing the operating frequency of the compressor according to a first adjustment speed in response to the absolute value of the first difference being greater than a first set threshold value and the inner tube temperature being greater than the first set temperature, and decreasing the operating frequency of the compressor according to a second adjustment speed in response to the absolute value of the first difference being greater than the first set threshold value and the inner tube temperature being less than the first set temperature. Thus, when the inner tube temperature is greater than the first set temperature and the difference between the two is large, the operating frequency of the compressor can be increased according to the first adjustment speed to reduce the inner tube temperature, and when the inner tube temperature is less than the first set temperature and the difference between the two is large, the operating frequency of the compressor can be decreased according to the second adjustment speed to increase the inner tube temperature, so that the inner tube temperature is maintained within a certain temperature range, which helps to improve the frosting effect.

[0167] It should be noted that the first set threshold is not too limited, for example, it can be 3° C. The first to second adjustment speeds are not too limited, for example, the first adjustment speed is increased by 2 Hz every 30 seconds, and the second adjustment speed is decreased by 2 Hz every 30 seconds.

[0168] In some examples, the method further includes maintaining the operating frequency of the compressor in response to the absolute value of the first difference being less than or equal to the first set threshold value. Thus, when the difference between the inner tube temperature and the first set temperature is small, the operating frequency of the compressor can be maintained so that the inner tube temperature is kept within a certain temperature range, which helps to improve the frosting effect.

[0169] In one embodiment, based on the first difference, the operating frequency of the compressor of the air conditioner is adjusted, including obtaining a mapping relationship between a candidate range and a candidate adjustment strategy for the operating frequency of the compressor, determining a target range in which the first difference is located from multiple candidate ranges, obtaining a candidate adjustment strategy mapped to the target range as a target adjustment strategy, and adjusting the operating frequency of the compressor according to the target adjustment strategy. It is understandable that different candidate ranges may have different candidate adjustment strategies mapped to them.

[0170] In one embodiment, before adjusting the operating frequency of the compressor of the air conditioner based on the first difference, the method further includes controlling the compressor to continuously operate at the current operating frequency for a set time in response to the air conditioner entering the frosting stage. It should be noted that there is no excessive limitation on the set time, for example, it can be 1 minute.

[0171] The self-cleaning method of the air conditioner provided by the embodiment of the present disclosure, in response to the air conditioner entering the frosting stage, turns off the fresh air device, obtains the first difference between the inner tube temperature of the air conditioner and the first set temperature, and adjusts the operating frequency of the compressor of the air conditioner based on the first difference. Thus, in the frosting stage, the fresh air device is turned off, and considering the first difference between the inner tube temperature of the air conditioner and the first set temperature, the operating frequency of the compressor is adjusted, so that the inner tube temperature is maintained within a certain temperature range, which helps to improve the frosting effect.

[0172] Fig.10 is a flow chart showing a self-cleaning method for an air conditioner according to another exemplary embodiment. Fig.10 As shown, the self-cleaning method of the air conditioner according to the embodiment of the present disclosure includes the following steps.

[0173] S1001, in response to the air conditioner entering the defrost stage, continue to close the fresh air device.

[0174] In one embodiment, the method further includes adjusting the operating frequency of the compressor to a set frequency and adjusting the opening of the expansion valve to a set opening in response to the air conditioner entering the defrosting stage. It should be noted that the set frequency is not too limited, for example, it can be 30 Hz, and the set opening is not too limited, for example, it can be 300P.

[0175] It should be noted that there is no excessive limitation on the running time of the defrost stage, for example, it can be 30 to 60 minutes.

[0176] S1002, obtaining a second difference between the inner pipe temperature of the air conditioner and a second set temperature.

[0177] It should be noted that there are no excessive restrictions on the second set temperature, for example, it may include the target inner tube temperature of the air conditioner in the defrosting stage, for example, the second set temperature may be 56°C.

[0178] S1003: Based on the second difference, adjust the rotation speed of the indoor fan in the main air duct.

[0179] In one embodiment, based on the second difference, the speed of the indoor fan in the main air duct is adjusted, including increasing the speed of the indoor fan according to the third adjustment speed in response to the absolute value of the second difference being greater than the second set threshold and the inner tube temperature being greater than the second set temperature, and reducing the speed of the indoor fan according to the fourth adjustment speed in response to the absolute value of the second difference being greater than the second set threshold and the inner tube temperature being less than the second set temperature. Thus, when the inner tube temperature is greater than the second set temperature and the difference between the two is large, the speed of the indoor fan can be increased according to the third adjustment speed to reduce the inner tube temperature, and when the inner tube temperature is less than the second set temperature and the difference between the two is large, the speed of the indoor fan can be reduced according to the fourth adjustment speed to increase the inner tube temperature, so that the inner tube temperature is kept within a certain temperature range, which helps to improve the defrosting effect.

[0180] It should be noted that the second setting threshold is not too limited, for example, it can be 1° C. The third to fourth adjustment speeds are not too limited, for example, the third adjustment speed can include 30r / s (revolutions / second), 20r / s, 10r / s, and the fourth adjustment speed is 10r / s.

[0181] In some examples, before reducing the speed of the indoor fan according to the fourth adjustment speed, it also includes identifying that the speed of the indoor fan is greater than the minimum speed of the indoor fan in the defrost stage. Therefore, when the speed of the indoor fan is greater than the minimum speed of the indoor fan in the defrost stage, the speed of the indoor fan can be reduced according to the fourth adjustment speed to avoid the speed of the indoor fan being too low. It should be noted that there is no excessive limitation on the minimum speed of the indoor fan in the defrost stage, for example, it can be 500r / min.

[0182] In some examples, the absolute value of the second difference is positively correlated with the third adjustment speed. Therefore, when the inner tube temperature is greater than the second set temperature and the difference between the two is large, the greater the difference between the inner tube temperature and the second set temperature, the faster the adjustment speed of the indoor fan speed is, and the indoor fan speed can be increased according to the faster adjustment speed, so that the indoor fan speed can be quickly adjusted and the adjustment speed of the indoor fan speed can be flexibly configured.

[0183] In some examples, increasing the speed of the indoor fan according to the third adjustment speed includes increasing the speed of the indoor fan according to the fifth adjustment speed in response to the absolute value of the second difference being greater than the third set threshold, increasing the speed of the indoor fan according to the sixth adjustment speed in response to the absolute value of the second difference being less than or equal to the third set threshold and the absolute value of the second difference being greater than the fourth set threshold, and increasing the speed of the indoor fan according to the seventh adjustment speed in response to the absolute value of the second difference being less than or equal to the fourth set threshold, wherein the third set threshold is greater than the fourth set threshold, the fourth set threshold is greater than the second set threshold, the fifth adjustment speed is greater than or equal to the sixth adjustment speed, and the sixth adjustment speed is greater than or equal to the seventh adjustment speed.

[0184] It should be noted that there are not too many restrictions on the third to fourth setting thresholds, for example, the third setting threshold can be 7°C, the fourth setting threshold can be 3°C, and there are not too many restrictions on the fifth to seventh adjustment speeds, for example, the fifth adjustment speed is 30r / s, the sixth adjustment speed is 20r / s, and the seventh adjustment speed is 10r / s.

[0185] In some examples, before increasing the speed of the indoor fan according to the fifth adjustment speed, it also includes identifying that the speed of the indoor fan is less than the fifth set speed. Thus, the speed of the indoor fan can be increased according to the fifth adjustment speed only when the speed of the indoor fan is less than the fifth set speed, so as to avoid the speed of the indoor fan being too high.

[0186] Before increasing the speed of the indoor fan according to the sixth adjustment speed or the seventh adjustment speed, it also includes identifying that the speed of the indoor fan is less than the maximum speed of the indoor fan in the defrosting stage. Therefore, when the speed of the indoor fan is less than the maximum speed of the indoor fan in the defrosting stage, the speed of the indoor fan can be increased according to the sixth adjustment speed or the seventh adjustment speed to avoid excessive speed of the indoor fan.

[0187] It should be noted that there are no excessive restrictions on the fifth set speed and the maximum speed of the indoor fan in the defrost stage. For example, the fifth set speed is greater than or equal to the maximum speed of the indoor fan in the defrost stage. For example, the fifth set speed is 1200r / min, and the maximum speed of the indoor fan in the defrost stage is 900r / min.

[0188] In some examples, the method further includes maintaining the speed of the indoor fan in response to the absolute value of the second difference being less than or equal to the second set threshold. Thus, when the difference between the inner tube temperature and the second set temperature is small, the speed of the indoor fan can be maintained so that the inner tube temperature is kept within a certain temperature range, which helps to improve the defrosting effect.

[0189] In one embodiment, based on the second difference, the speed of the indoor fan in the main air duct is adjusted, including obtaining a mapping relationship between a candidate range and a candidate adjustment strategy for the speed of the indoor fan, determining a target range in which the second difference is located from multiple candidate ranges, obtaining a candidate adjustment strategy mapped to the target range as a target adjustment strategy, and adjusting the speed of the indoor fan according to the target adjustment strategy. It is understandable that different candidate ranges may have different candidate adjustment strategies mapped to them.

[0190] In one embodiment, before adjusting the speed of the indoor fan in the main air duct based on the second difference, it also includes turning on the indoor fan in response to the air conditioner entering the defrost stage and the internal tube temperature being greater than or equal to the third set temperature, and controlling the indoor fan to continuously run at the lowest speed in the defrost stage for a set time.

[0191] It should be noted that there are not too many restrictions on the third set temperature, for example, it may include the critical temperature for turning on the indoor fan in the defrost stage, for example, the third set temperature may be 40°C, and there are not too many restrictions on the set time, for example, it may be 30s.

[0192] The self-cleaning method of the air conditioner provided by the embodiment of the present disclosure, in response to the air conditioner entering the defrosting stage, continues to close the fresh air device, obtains the second difference between the inner tube temperature of the air conditioner and the second set temperature, and adjusts the speed of the indoor fan in the main air duct based on the second difference. Thus, in the defrosting stage, the fresh air device continues to be closed, and considering the second difference between the inner tube temperature of the air conditioner and the second set temperature, the speed of the indoor fan is adjusted, so that the inner tube temperature is maintained within a certain temperature range, which helps to improve the defrosting effect.

[0193] Fig.11 is a flow chart showing a self-cleaning method for an air conditioner according to another exemplary embodiment. Fig.11 As shown, the self-cleaning method of the air conditioner according to the embodiment of the present disclosure includes the following steps.

[0194] S1101, in response to the air conditioner entering the defrosting stage and the inner tube temperature of the air conditioner being greater than or equal to a fourth set temperature, reducing the speed of the outdoor fan of the air conditioner to a first set speed.

[0195] It should be noted that there are no excessive restrictions on the fourth set temperature, for example, it can be 52° C., and there are no excessive restrictions on the first set speed, for example, it can be the speed corresponding to the low wind gear of the outdoor fan.

[0196] S1102, in response to the inner tube temperature being greater than the fifth set temperature and the temperature of the air conditioner's electronic control device being less than the sixth set temperature, controlling the outdoor fan to stop running, wherein the fourth set temperature is less than the fifth set temperature.

[0197] It should be noted that there are no excessive restrictions on the fourth set temperature, for example, it may include the maximum temperature allowed by the inner tube temperature, for example, the fourth set temperature may be 58°C. There are no excessive restrictions on the fifth set temperature, for example, it may include the maximum temperature allowed by the electronic control device, for example, the fifth set temperature may be 85°C. There are no excessive restrictions on the electronic control device, for example, it may include IPM (Intelligent Power Module), which is an integrated circuit chip.

[0198] The self-cleaning method of the air conditioner provided in the embodiment of the present disclosure reduces the speed of the outdoor fan of the air conditioner to the first set speed in response to the air conditioner entering the defrost stage and the inner tube temperature of the air conditioner being greater than or equal to the fourth set temperature. That is, in the defrost stage, when the inner tube temperature of the air conditioner is greater than the fourth set temperature, the speed of the outdoor fan can be reduced to the first set speed. When the inner tube temperature is greater than the fifth set temperature and the temperature of the electronic control device is relatively low, the outdoor fan can be controlled to stop running to reduce the inner tube temperature, thereby preventing the inner tube temperature from being too high and improving the reliability of the air conditioner operation.

[0239] The self-cleaning device of the air conditioner provided in the embodiment of the present disclosure performs multiple rounds of self-cleaning on the air conditioner.

Although Fig.13 Not shown in the figure, a disk drive for reading and writing to a removable non-volatile disk (e.g., a "floppy disk"), and an optical disk drive for reading and writing to a removable non-volatile optical disk (e.g., a CD-ROM, a DVD-ROM, or other optical media) may be provided. In these cases, each drive may be connected to the bus 1303 via one or more data medium interfaces. The memory 1301 may include at least one program product having a set (e.g., at least one) of program modules that are configured to perform the functions of the various embodiments of the present disclosure.

[0249] It should be noted that the implementation process and technical principles of the electronic device of this embodiment refer to the aforementioned explanation of the self-cleaning method of the air conditioner of the embodiment of the present disclosure, and will not be repeated here.

[0250] The electronic device provided by the embodiment of the present disclosure can execute the self-cleaning method of the air conditioner as described above, and perform multiple rounds of self-cleaning on the air conditioner. During each round of self-cleaning, in response to the air conditioner entering the condensation stage, the fresh air device is turned on, and the fresh air is humidified by the humidification component. The fresh air outlet corresponding to the fresh air outlet mode of the fresh air device is determined as the first target air outlet, and the humidified fresh air discharged from the first target air outlet is controlled to enter the main air duct, and the humidified fresh air is made to flow through the indoor heat exchanger. During the condensation stage of at least one round of self-cleaning, the fresh air outlet mode is switched. Therefore, during the condensation stage, the fresh air can be humidified by the humidification component, and the humidified fresh air discharged from the first target air outlet is controlled to enter the main air duct, and the humidified fresh air is made to flow through the indoor heat exchanger, which can increase the air humidity around the indoor heat exchanger, thereby generating more condensed water on the outer surface of the indoor heat exchanger. In addition, during the condensation stage of at least one round of self-cleaning process, the fresh air outlet mode is switched, so that a variety of fresh air outlet modes can be used for condensation during multiple rounds of self-cleaning processes. The humidified fresh air can enter the main air duct from different fresh air outlets, which helps to evenly generate condensed water on the outer surface of the indoor heat exchanger, and the air conditioner can be subjected to multiple rounds of self-cleaning, which helps to improve the self-cleaning effect of the indoor heat exchanger.
