It should be understood that the following description is only a schematic embodiment of the present application and does not constitute any special limitation on the present application.

[0051] Embodiments of the first aspect of the application provide a filter screen assembly, comprising Figures 1 to 5 As shown in the drawings, the filter screen assembly comprises:

[0052] a filter screen 100, the filter screen 100 being installed at an air inlet 201 of an air conditioner housing 200;

[0053] a baffle 300, the baffle 300 being slidingly connected to the air conditioner housing 200 and being switchable between a shielding position and a storage position; in the shielding position, the baffle 300 slides to the outside of the filter screen 100 and covers the air inlet 201; in the storage position, the baffle 300 slides to be stored in the air conditioner housing 200.

[0054] In the filter screen assembly provided by the application, the filter screen 100 and the baffle 300 are included. The filter screen 100 is installed at the air inlet 201. The baffle 300 is slidingly connected to the air conditioner housing 200. The baffle 300 is switchable between the shielding position and the storage position. As shown in the drawings, Figure 3 in the shielding position, the baffle 300 slides to the outside of the filter screen 100 and covers the air inlet 201. As shown in the drawings, Figure 1 in the storage position, the baffle 300 slides to be stored in the air conditioner housing 200 and opens the air inlet 201. Figure 2 The state shown in the drawings is an intermediate state in which the baffle 300 is switched from the storage position to the shielding position or from the shielding position to the storage position. When the air conditioner is normally running, the baffle 300 is switched to the storage position, and air enters the inside of the air conditioner after passing through the filtering effect of the filter screen 100. When the filter screen 100 needs to be cleaned, the baffle 300 is switched to the shielding position, and dust on the filter screen 100 cannot spread to the indoor environment through the air inlet 201, thereby effectively protecting the indoor environment.

[0055] In an embodiment of the application, the filter screen assembly further comprises a vibration mechanism. The vibration mechanism is connected to the baffle 300. In the shielding position, the vibration mechanism is in contact with the filter screen 100 to drive the filter screen 100 to vibrate.

[0056] Further, in an embodiment of the application, the vibration mechanism comprises a vibration module, a power supply module 401 and a charging module 402. The power supply module 401 is connected to the vibration module to supply power to the vibration module. The power supply module 401 is fixed to the baffle 300, and the charging module 402 is installed on the inside of the air conditioner housing 200. In the storage position, the charging module 402 is plug-in connected to the power supply module 401 to charge the power supply module 401.

[0057] For example, as shown in the drawings, Figure 4 and Figure 5As shown, the vibration mechanism includes a vibration module, a power module 401 and a charging module 402. The vibration module includes a plurality of vibration bodies. The power module 401 is connected with each vibration body. The power module 401 includes but is not limited to a battery or a mobile power supply, etc. The power module 401 is connected with each vibration body. A power switch can be provided on the power module 401. When the vibration body needs to perform a vibration operation, the power switch is turned on, so that the power module 401 supplies power to the vibration body and drives the vibration body to vibrate. When the vibration body does not need to perform a vibration operation, the power switch is turned off.

[0058] The vibration module and the power module 401 are fixed to the baffle 300. The charging module 402 is fixed to the inner side of the shell 200. The charging module 402 is provided corresponding to the power module 401. The vibration module is provided corresponding to the filter screen 100. When the baffle 300 is switched to the shielding position, each vibration body can contact the filter screen 100 to drive the filter screen 100 to perform a vibration cleaning operation. It should be noted that the number and arrangement position of the vibration bodies can be adjusted according to actual needs. In an embodiment of the present application, when the baffle 300 is switched to the shielding position, the vibration bodies should be arranged as much as possible to cover the entire filter screen 100. When the baffle 300 is switched to the storage position, the power module 401 is connected with the charging module 402, so that the charging module 402 can charge the power module 401 to prepare for the next vibration operation.

[0059] In an embodiment of the present application, the filter screen assembly further includes a baffle driving device 500, an air duct pressure detection device and a control device.

[0060] The baffle driving device 500 is connected with the baffle 300 and is used to drive the baffle 300 to switch the working state. The air duct pressure detection device is installed in the air duct of the air conditioner and is used to detect the actual pressure value of the air duct. The control device is connected with the air duct pressure detection device, the baffle driving device 500 and the vibration mechanism, and is used to control the working state of the baffle driving device 500 and the vibration mechanism based on the detection result of the air duct pressure detection device.

[0061] Further, in an embodiment of the present application, the baffle driving device 500 includes a motor 501, a gear 502 and a rack 503.

[0062] The motor 501 is installed to the inner side of the air conditioner shell 200. The output shaft of the motor 501 is connected with the gear 502. The gear 502 is engaged with the rack 503. The rack 503 is connected to the inner side of the baffle 300.

[0063] Specifically, as shown in FIG. 6, the baffle 300 is provided with a plurality of through holes 301. The vibration bodies are arranged in the through holes 301. Figure 4 and Figure 5As shown, the air conditioner is a cylindrical cabinet type air conditioner. The air conditioner shell 200 is a cylindrical shell 200. The baffle 300 and the filter screen 100 are both arc-shaped structures. The inner side of the baffle 300 is provided with a rack 503. The motor 501 is fixed to the inside of the shell 200. The output shaft of the motor 501 is connected with a gear 502. The gear 502 is engaged with the rack 503. When the motor 501 is started, it can drive the gear 502 to rotate, and the rack 503 is engaged with and moves with the gear 502. Thus, the baffle 300 can be driven to slide and convert between the shielding position and the storage position.

[0064] The air duct of the air conditioner is provided with an air duct pressure detection device. According to the detection result of the air duct pressure detection device, it can be judged whether the filter screen 100 is in a blocked state, and further, it can be determined whether the filter screen 100 needs to be cleaned. It should be understood here that the standard air duct pressure range corresponding to different wind speed states is different.

[0065] The control device is connected with the air duct pressure detection device, the vibration mechanism and the baffle driving device 500. For example, the control device is connected with the power switch of the vibration mechanism and the motor 501 of the baffle driving device 500. The control device receives the actual air duct pressure value detected by the air duct pressure detection device, and compares it with the standard air duct pressure range under the corresponding wind speed.

[0066] When the actual air duct pressure value is within the standard air duct pressure range, it is determined that the filter screen 100 does not need to be cleaned, the control device controls the power switch of the vibration mechanism to switch to the off state, and controls the motor 501 to drive the gear 502 to rotate, so that the rack 503 drives the baffle 300 to slide to the storage position.

[0067] When the actual air duct pressure value is outside the standard air duct pressure range, it is determined that the filter screen 100 needs to be cleaned, the control device controls the motor 501 to drive the gear 502 to rotate, so that the rack 503 drives the baffle 300 to slide to the shielding position, and controls the power switch of the vibration mechanism to switch to the on state, so that the vibration body vibrates and drives the filter screen 100 to vibrate and clean dust.

[0068] In an embodiment of the present application, the filter screen 100 comprises a frame, a filter screen body and a clamping groove. The clamping groove is arranged at the air inlet 201. The filter screen body is installed in the frame. The frame is clamped in the clamping groove;

[0069] The baffle 300 comprises a baffle body, a limiting body and a sliding groove. The sliding groove is arranged at the air inlet 201 and is located outside the clamping groove. The baffle body is slidingly installed in the sliding groove. The limiting body is arranged at one end of the baffle body and is limited in the sliding groove.

[0070] For example, the filter screen body is fixed in the frame. The upper and lower sides of the air inlet 201 are respectively provided with a clamping groove. The depth of the clamping groove is X, the longitudinal length of the air inlet 201 is Y, the longitudinal length of the frame is A, and Y+X<A<Y+2X. When the filter screen 100 is installed, the upper side or the lower side of the frame is first inserted into the corresponding clamping groove, and then the frame is slightly bent and deformed and inserted into the other corresponding clamping groove.

[0071] The upper and lower sides of the air inlet 201 are also provided with a sliding groove. The sliding groove is located outside the clamping groove. One end of the baffle body is provided with a limiting body. For example, the limiting body includes but is not limited to a limiting block. One end of the baffle 300 is slidably connected to the sliding groove, and the end of the baffle 300 in the sliding groove is detachably installed with a limiting block. The limiting block can be limited in the sliding groove to prevent the baffle body from sliding out of the sliding groove.

[0072] The embodiment of the second aspect of the application provides an air conditioner, which comprises a shell 200 and a filter screen assembly as described above. The filter screen assembly is connected with the shell 200.

[0073] Further, since the air conditioner comprises the filter screen assembly as described above, it also has the advantages as described above.

[0074] The embodiment of the third aspect of the application provides a cleaning control method for cleaning the above-mentioned air conditioner, which comprises the following steps:

[0075] In response to the cleaning start instruction, the baffle 300 is switched from the storage position to the shielding position;

[0076] The baffle 300 shields the filter screen 100, and the filter screen 100 is cleaned.

[0077] Further, in an embodiment of the application, the step of responding to the cleaning start instruction specifically comprises:

[0078] The actual pressure value of the air duct and the corresponding air duct standard pressure range under the current wind speed state are obtained;

[0079] The actual pressure value of the air duct is determined to be outside the air duct standard pressure range, and the cleaning start instruction is generated.

[0080] In an embodiment of the application, the step of cleaning the filter screen 100 specifically comprises:

[0081] The air conditioner is controlled to stop running;

[0082] The baffle 300 is switched to the shielding position, and the air outlet 202 of the air conditioner is closed;

[0083] The vibration mechanism is controlled to vibrate to clean the filter screen 100.

[0084] Further, in one embodiment of the present application, the step of cleaning the filter screen 100 further comprises the following steps:

[0085] obtaining an actual vibration duration of the vibration mechanism and a target vibration duration;

[0086] determining that the actual vibration duration is greater than or equal to the target vibration duration, and generating a cleaning completion instruction.

[0087] Specifically, different wind speeds correspond to different air duct standard pressure ranges. During the operation of the cleaning control method, the current wind speed state should be obtained, and the corresponding air duct standard pressure range is obtained according to the current wind speed. The actual pressure value of the air duct is detected by the air duct pressure detection device, and the relationship between the actual pressure value of the air duct and the air duct standard pressure range is judged to determine whether to generate a cleaning start instruction.

[0088] For example, if the actual pressure value of the air duct is within the air duct standard pressure range, it is judged that the cleanliness of the filter screen 100 meets the standard, and cleaning is not required, and the air conditioner can operate normally. If the actual pressure value of the air duct is outside the air duct standard pressure range, it is judged that the cleanliness of the filter screen 100 does not meet the standard, and cleaning is required. At this time, a cleaning start instruction is generated.

[0089] When the cleaning start instruction is generated, the air conditioner should be controlled to stop running first. Then, the baffle 300 is switched to the shielding position, and the air outlet 202 on the air conditioner is closed. Specifically, the motor 501 of the baffle driving device 500 is controlled to rotate, so that the motor 501 drives the gear 502 and the rack 503 to drive the baffle 300 to slide to a position shielding the air inlet 201. At this time, the vibration module in the vibration mechanism is in contact with the filter screen 100. The power switch of the vibration mechanism is controlled to be turned on, so that the power module 401 drives the vibration module to vibrate. Thus, the vibration module drives the filter screen 100 to vibrate to clean the dust on the filter screen 100. The dust on the filter screen 100 falls into the liquid collecting disc at the bottom of the air conditioner housing 200.

[0090] During the cleaning process, the actual vibration duration of the vibration mechanism is obtained, and the actual vibration duration is compared with the target vibration duration. When the actual vibration duration is less than the target vibration duration, the vibration mechanism is controlled to continue vibrating. When the actual vibration duration is greater than or equal to the target vibration duration, it indicates that the cleaning has been completed, and a cleaning completion instruction is generated.

[0091] It should be noted that when the baffle is switched to the shielding position, the charging module of the vibration mechanism is separated from the power module, and the power module is powered as an independent power supply for the vibration module. When the baffle is switched to the storage position, the charging module of the vibration mechanism is connected with the power module, the charging module is powered on, and the charging module charges the power module to prepare for the next vibration action.

[0092] In one embodiment of the present application, after the step of generating the cleaning completion instruction when the actual vibration duration is greater than or equal to the target vibration duration, the method further comprises:

[0093] In response to the cleaning completion instruction, the vibration mechanism is controlled to stop vibrating;

[0094] The baffle 300 is controlled to switch to the storage position, and the air outlet 202 of the air conditioner is opened;

[0095] The air conditioner is controlled to operate normally;

[0096] An actual pressure value of the air duct and an air duct standard pressure range corresponding to a current air speed state are obtained;

[0097] When the actual pressure value of the air duct is within the air duct standard pressure range, the air conditioner is controlled to continue operating normally;

[0098] When the actual pressure value of the air duct is outside the air duct standard pressure range, the air conditioner is controlled to stop operating, and an alarm instruction is generated.

[0099] For example, in response to the cleaning completion instruction, the vibration mechanism is controlled to stop vibrating. When the vibration mechanism stops vibrating, the baffle 300 is controlled to switch to the storage position, and the air outlet 202 of the air conditioner is opened. Specifically, the control device controls the motor 501 of the baffle driving device 500 to rotate, so that the motor 501 drives the gear 502 and the rack 503 to slide the baffle 300 to be stored in the housing 200, and the air inlet 201 is opened. Subsequently, the air conditioner is controlled to operate normally, and an actual pressure value of the air duct and an air duct standard pressure range corresponding to a current air speed state are obtained. Thus, it is determined whether the filter screen 100 is cleaned up to the standard. If the actual pressure value of the air duct is within the air duct standard pressure range, it is judged that the filter screen 100 has been cleaned up to the standard, and the air conditioner can continue to operate normally. If the actual pressure value of the air duct is outside the air duct standard pressure range, it is judged that the filter screen 100 is not cleaned up to the standard. At this time, there may be a filter screen assembly failure problem or stubborn impurities on the filter screen 100 that cannot be cleaned. The control device controls the air conditioner to stop operating, and generates an alarm instruction. The alarm instruction can control the alarm sound prompt or the alarm light to flash. The staff performs corresponding auxiliary operations according to the above alarm prompt.

[0100] According to the above cleaning control method, the full-automatic cleaning operation of the filter screen 100 can be realized more simply and efficiently.

[0101] It should be pointed out finally that the above embodiments are only used to illustrate the technical solutions of the present application, but not to limit the same; and although the present application has been described in detail with reference to the foregoing embodiments, it should be appreciated by those skilled in the art that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features thereof can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
