[0002] At present, although an air conditioner inlet is provided with a filter screen, dust, bacteria and the like can still fall into the air conditioner and adhere to the evaporator and the filter screen because the filter screen is a mesh with holes. This can easily cause the air blown out by the air conditioner to have dust or bacteria, so that the air blown out by the air conditioner is not clean.

[0003] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

[0004] The air conditioner in the related art cannot control the running state of the filter screen, and the filter screen cannot be closed in the open state, so that dust is easily accumulated on the filter screen. When cleaning the filter screen of the air conditioner, cleaning is usually performed according to a fixed cleaning frequency or cleaning period. In the case of serious dust accumulation, it is difficult to clean thoroughly, so that the air blown out by the air conditioner is not clean. In order to ensure that the air blown out by the air conditioner is clean, the cleaning frequency or cleaning period of the filter screen is usually increased, which can easily increase the energy consumption of the air conditioner. Thus, it is difficult to ensure that the air blown out by the air conditioner is clean and to reduce the energy consumption of the air conditioner at the same time.

[0005] The foregoing general description and the following description are only exemplary and explanatory and are not intended to limit the present application. SUMMARY

[0029] In order to enable a more detailed understanding of the features and technical content of the embodiments of the present disclosure, the implementation of the embodiments of the present disclosure is described in detail below, and the accompanying drawings are used for reference only and do not limit the embodiments of the present disclosure. In the following technical description, for the convenience of explanation, through multiple details, a sufficient understanding of the disclosed embodiments is provided. However, one or more embodiments can still be implemented without these details. In other cases, well-known structures and devices can be simplified to illustrate the drawings.

[0030] The terms "first", "second", and the like in the specification and claims of the embodiments of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data used in this way can be exchanged under appropriate circumstances, so as to implement the embodiments of the present disclosure described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0031] Unless otherwise specified, the term "a plurality of" means two or more.

[0032] In the embodiments of the present disclosure, the character " / " represents a "or" relationship between the objects before and after. For example, A / B represents: A or B.

[0033] The term "and / or" is a description of the association between objects, which means that there can be three relationships. For example, A and / or B, which means: A or B, or, A and B, three kinds of relationship.

[0034] The term "corresponding" can refer to an association or binding relationship, A corresponds to B means that there is an association or binding relationship between A and B.

[0035] In combination Figures 1 to 3 As shown, Figure 1 is a structural schematic diagram of an air conditioner provided by an embodiment of the present disclosure. Figure 2 is a structural schematic diagram of a filter screen device in a ventilation state provided by an embodiment of the present disclosure. Figure 3is a structural schematic diagram of a filter screen device in a non-ventilation state provided by an embodiment of the present disclosure. The filter screen device 2 is arranged in the air conditioner 1. The filter screen device 2 is configured to be controlled to switch the operation state. The operation state is used to represent that the filter screen device is in a ventilation state and / or a non-ventilation state in a first preset time period. In some embodiments, when the air conditioner is started to operate, the air conditioner controls the filter screen device to be turned on, at which time the filter screen device is in the ventilation state. When the air conditioner is turned off, the air conditioner controls the filter screen device to be turned off, at which time the filter screen device is in the non-ventilation state. In this way, since the filter screen is opened when the filter screen device is in the ventilation state, and the filter screen is closed when the filter screen device is in the non-ventilation state, the filter screen device is turned on when the air conditioner is operated, and the filter screen device is also turned off when the air conditioner is turned off, so that dust is not easily attached to the filter screen when the air conditioner is turned off. In a certain extent, the cleaning frequency or cleaning period of the filter screen device of the air conditioner can be reduced, and the filter screen device is cleaned when the cleaning interval of the filter screen device exceeds the preset time length. Thus, clean air can be blown out by the air conditioner, and energy consumption can be saved.

[0036] In combination with Figure 4 the present disclosure provides a method for controlling an air conditioner, the air conditioner being arranged with a filter screen device, the filter screen device being configured to be controlled to switch the operation state. The operation state is used to represent that the filter screen device is in a ventilation state and / or a non-ventilation state in a preset time period. The method comprises:

[0037] In step S401, the air conditioner acquires the cleaning interval of the filter screen device.

[0038] In step S402, the air conditioner controls the operation state of the filter screen device according to the cleaning interval.

[0039] In step S403, the air conditioner controls the air conditioner to clean the filter screen device in the operation state.

[0040] By using the method for controlling the air conditioner provided by the present disclosure, the cleaning interval of the filter screen device is acquired, the operation state of the filter screen device is controlled according to the cleaning interval, and the air conditioner is controlled to clean the filter screen device in the operation state. In this way, by arranging the filter screen device capable of switching the operation state in the air conditioner, the operation state of the filter screen device is controlled by the cleaning interval of the filter screen device. Thus, cleaning the filter screen device in the corresponding operation state can make the air conditioner blow out clean air, and the filter screen device does not need to be cleaned frequently. Thus, clean air can be blown out by the air conditioner, and the energy consumption of the air conditioner can be reduced.

[0041] Further, the air conditioner obtains the cleaning interval duration of the filter device, including: the air conditioner obtains a current time, and finds a last historical cleaning time of the filter device from a preset database. The cleaning interval duration is obtained by subtracting the current time from the historical cleaning time. The historical cleaning time of the filter device is stored in the preset database.

[0042] Further, the air conditioner controls the running state of the filter device according to the cleaning interval duration, including: when the cleaning interval duration is less than a second preset duration, the air conditioner obtains a shutdown duration of the air conditioner. The running state of the filter device is controlled according to the cleaning interval duration and the shutdown duration.

[0043] In some embodiments, the second preset duration is 720h.

[0044] Further, the air conditioner obtains the shutdown duration of the air conditioner, including: the air conditioner obtains a current time, and finds a last historical shutdown time of the filter device from a preset database. The shutdown duration is obtained by subtracting the current time from the historical shutdown time. The historical shutdown time of the filter device is stored in the preset database.

[0045] Further, the air conditioner controls the running state of the filter device according to the cleaning interval duration and the shutdown duration, including: when the cleaning interval duration is less than a second preset duration, and the shutdown duration is greater than or equal to a first preset duration, the running state of the filter device in a first preset time period after the current time is switched to a non-ventilation state. The first preset duration is 360h, and the second preset duration is 720h. The first preset time period represents a cleaning duration of the air conditioner cleaning the filter device in the non-ventilation state. In this way, since the filter of the filter device is open in the ventilation state, and the filter of the filter device is closed in the non-ventilation state. When the cleaning interval duration is less than the second preset duration, and the shutdown duration is greater than or equal to the first preset duration, it is considered that the time from the last cleaning of the filter device is not long, and the filter device in the ventilation state does not need to be cleaned at this time, and only cleaning the filter device in the non-ventilation state can achieve filter cleaning.

[0046] In some embodiments, the cleaning duration of the air conditioner cleaning the filter device in the non-ventilation state is 0.5h, and the first preset time period is 0.5h.

[0047] In some embodiments, the current time is "2023-07-23, 23:00", and the first preset time period is 0.5h. When the cleaning interval duration is less than 720h and the shutdown duration of the air conditioner is greater than or equal to 360h, the air conditioner switches the running state of the filter device to the non-ventilation state within 0.5h after "2023-07-23, 23:00". That is, the running state of the filter device in the time period of "2023-07-23, 23:00"-"2023-07-23, 23:30" is the non-ventilation state. The air conditioner controls the cleaning of the filter device in the non-ventilation state. And after the cleaning is completed, the running state of the filter device is switched to the ventilation state. This facilitates air supply according to user needs.

[0048] Further, the air conditioner controls the running state of the filter device according to the cleaning interval duration, including: the air conditioner switches the running state of the filter device to the non-ventilation state when the cleaning interval duration is greater than or equal to the second preset duration, and switches the running state of the filter device to the ventilation state after the interval first preset time period. The second preset duration is 720h. In this way, when the cleaning interval duration is greater than or equal to the second preset duration, it is considered that a long time has passed since the last cleaning of the filter device, and the filter device in the non-ventilation state and the filter device in the ventilation state need to be cleaned respectively.

[0049] In some embodiments, the current time is "2023-07-23, 23:00", and the first preset time period is 0.5h. When the cleaning interval duration is greater than or equal to 720h, the air conditioner switches the running state of the filter device to the non-ventilation state. And the running state of the filter device is switched to the ventilation state after 0.5h. This facilitates cleaning of the filter device in the non-ventilation state and the filter device in the ventilation state respectively. Thus, comprehensive cleaning is achieved, so that the air conditioner can blow clean air.

[0050] Further, after the air conditioner obtains the cleaning interval duration of the filter device, the air conditioner further obtains the shutdown duration of the air conditioner. When the cleaning interval duration is less than the second preset duration and the shutdown duration is less than the first preset duration, it is determined that the filter device is not cleaned. In this way, when the cleaning interval duration is less than the second preset duration and the shutdown duration is less than the first preset duration, it is considered that the shutdown duration and the cleaning interval duration of the air conditioner are not long, and the filter device does not need to be cleaned.

[0051] Further, the air conditioner obtains the length of time that the air conditioner has been turned off, including: the air conditioner obtains the current time, and finds the last historical turn-off time of the filter device from a preset database. The length of time that the air conditioner has been turned off is obtained by subtracting the current time from the historical turn-off time. The historical turn-off time of the filter device is stored in the preset database.

[0052] Optionally, after the air conditioner controls the air conditioner to clean the filter device in the running state, the air conditioner further includes: the air conditioner obtains a user control requirement, and controls the air conditioner to run according to the user control requirement.

[0053] In some embodiments, the user control requirement includes controlling the air conditioner to run in a cooling mode or controlling the air conditioner to run in a heating mode, etc.

[0054] Optionally, after the air conditioner controls the air conditioner to run according to the user control requirement, the air conditioner further includes: in a case where a preset cleaning instruction is received, the air conditioner cleans the filter device in the ventilation state and the filter device in the non-ventilation state respectively. After the cleaning is completed, the running state of the filter device is switched to the ventilation state. In this way, the user can actively clean the filter device by issuing a cleaning instruction.

[0055] In some embodiments, in a case where a preset cleaning instruction is received, the air conditioner cleans the filter device in the ventilation state and the filter device in the non-ventilation state respectively, including: the air conditioner cleans the filter device in the ventilation state, and then switches the running state of the filter device to the non-ventilation state to clean the filter device in the non-ventilation state. In this way, when the user performs self-cleaning, the filter device in the ventilation state and the filter device in the non-ventilation state will both be cleaned, thereby ensuring the cleaning of the filter and enabling the air conditioner to blow clean air.

[0056] Optionally, after the air conditioner controls the air conditioner to run according to the user control requirement, the air conditioner further includes: the air conditioner controls the air conditioner to be turned off, switches the running state of the filter device to the non-ventilation state, and records the turn-off time of the air conditioner.

[0057] In some embodiments, the air conditioner records the turn-off time of the air conditioner, including: the air conditioner stores the turn-off time of the air conditioner as a historical turn-off time in a preset database.

[0058] Optionally, after the air conditioner controls the air conditioner to clean the filter device in the running state, the air conditioner further includes: the air conditioner stores the cleaning time of the filter device as a historical cleaning time in a preset database.

[0059] In some embodiments, the air conditioner further comprises: obtaining a continuous start-up time length of the air conditioner; and cleaning the filter screen device in the ventilation state and the filter screen device in the non-ventilation state respectively when the continuous start-up time length of the air conditioner is greater than or equal to a first preset time length.

[0065] In step S505, the air conditioner switches the operation state of the filter screen device to the non-ventilation state in a first preset time period after a current time. Then, step S506 is performed.

[0066] In step S506, the air conditioner controls the air conditioner to clean the filter screen device in the non-ventilation state, and records a cleaning time of the filter screen device. Then, step S511 is performed.

[0067] In step S507, the air conditioner switches the operation state of the filter screen device to the non-ventilation state. Then, step S508 is performed.

[0068] In step S508, the air conditioner controls the air conditioner to clean the filter screen device in the non-ventilation state. Then, step S509 is performed.

[0069] In step S509, the air conditioner switches the operation state of the filter screen device to the ventilation state. Then, step S510 is performed.

[0070] Step S510, the air conditioner controls the air conditioner to clean the filter screen device in the ventilation state, and records the cleaning time of the filter screen device. Then step S511 is performed.

[0071] Step S511, the air conditioner acquires the user control demand. Then step S512 is performed.
