The embodiment of the present disclosure discloses an electrostatic dust collection module, including: the dust collecting device comprises a dust collecting unit, a first detection device, a second detection device and a controller.
Wherein, dust collecting unit mainly used purifies the collection dirt processing to the air intake of air conditioner, and first detection device installs the air inlet side at dust collecting unit, and second detection device installs the air-out side at dust collecting unit, and first detection device is used for detecting the particulate matter content of the air inlet side of dust collecting unit, and second detection device is used for detecting the particulate matter content of the air-out side of dust collecting unit.
And the controller is used for analyzing whether the dust collecting unit needs to be cleaned or not.
As shown in connection with fig. 1, embodiments of the present disclosure provide a method for cleaning a dust collection unit, including:
s01, monitoring the first particulate matter content of the dust collection unit while the dust collection unit is operating.
S02, if the first particulate matter content does not match the reference value, monitoring a second particulate matter content of the dust collection unit.
And S03, determining the current dust collecting efficiency of the dust collecting unit in the current period according to the first particulate matter content and the second particulate matter content.
S04, if the current dust collecting efficiency does not match the preset efficiency, determining that the dust collecting unit needs to be cleaned.
The method is mainly used for determining whether the dust collection unit needs to be cleaned, in the implementation process, when the dust collection unit works, monitoring the first particulate matter content of the dust collection unit, judging whether the first particulate matter content is in the threshold range of the reference value, if the first particulate matter content is not in the threshold range of the reference value, starting to monitor the second particulate matter content of the dust collection unit, calculating the current dust collection efficiency of the dust collection unit in the current period according to the first particulate matter content and the second particulate matter content, judging whether the current dust collection efficiency is in the threshold range of the preset efficiency, and if the current dust collection efficiency is not in the threshold range of the preset efficiency, determining that the dust collection unit needs to be cleaned.
By adopting the method for cleaning the dust collecting unit, after the dust collecting unit is determined to need cleaning, the air conditioner can be controlled to self-clean the dust collecting unit, and a user can be reminded to manually clean or replace the dust collecting unit. The above triggering of self-cleaning or alerting requires two conditions to be met: firstly, the first particulate matter content of the dust collection unit is not matched with a reference value; secondly, the dust collecting efficiency of the dust collecting unit in the current period, which is determined according to the first particulate matter content and the second particulate matter content, is not matched with the preset efficiency.
This application is preferred to carry out air quality detection to one side in the air inlet side or the air-out side of collection dirt unit, when first particulate matter content does not match with the benchmark, gather second particulate matter content again, carry out air quality detection to the air inlet side of collection dirt unit or the opposite side in the air-out side, and calculate the collection dirt efficiency of current periodic collection dirt unit, match with efficiency of predetermineeing, this kind of warning mode is compared in real-time supervision collection dirt efficiency's mode, can effectively reduce the calculated amount, save the processing resources of air conditioner. In addition, the method adopts two factors of the reference value and the preset efficiency to carry out comprehensive judgment, and can reduce the influence of the environment where the air conditioner is located on the work of the dust collecting unit.
Optionally, after determining that the dust collecting unit needs to be cleaned, the method for cleaning the dust collecting unit further includes:
and S05, reminding the user of the cleaning mode.
It can be understood that after the dust collecting unit is determined to need to be cleaned, a prompt message for cleaning the dust collecting unit, such as a prompt message for starting a self-cleaning mode, a message for manually cleaning the dust collecting unit, or a message for replacing the dust collecting unit, can be pushed to a user. The push mode packet is not limited to, a telephone notification, a short message notification, a message push on various terminals with air conditioners associated with the user, a maintenance message push through a public number or a service number associated with the user, and the like.
Alternatively, the current dust collection efficiency is determined in the following manner:
C＝(A1-A2)/A1
wherein C is the current dust collecting efficiency of the current cycle, A1Is the particulate matter content on the air inlet side of the current period, A2The content of the particulate matters on the air outlet side in the current period.
As an example, in implementation, the particulate matter content on the air inlet side of the dust collection unit is monitored, when the particulate matter content on the air inlet side exceeds the threshold range of the first reference value, the particulate matter content on the air outlet side of the dust collection unit is subjected to supplementary detection, the current dust collection efficiency of the dust collection unit in the current period is calculated according to the particulate matter content on the air inlet side and the particulate matter content on the air outlet side, if the current dust collection efficiency is not matched with the threshold range of the preset efficiency, it is determined that the dust collection unit needs to be cleaned, then self-cleaning can be performed or a prompt message can be pushed to a user to prompt the cleaning or replacement of the dust collection unit.
As shown in fig. 2, optionally, if the first particulate content is the particulate content on the intake side, the method further comprises:
s11, obtaining current air quality information, adjusting a reference value according to the current air quality information, and obtaining an adjusted reference value;
s21, if the first particulate matter content does not match the reference value, monitoring a second particulate matter content of the dust collection unit, comprising: and monitoring the second particulate matter content of the dust collection unit if the first particulate matter content does not match the adjusted reference value.
It can be understood that, because the local environment has a large influence on the particulate matter content on the air inlet side of the air conditioner, if the particulate matter content on the air inlet side is matched with the constant first reference value, a certain error may exist, and the first particulate matter content is subjected to floating control by designing the floating first reference value. If local air quality is poor, the particulate matter content in the air is high, the first reference value is increased, and when the particulate matter content on the air inlet side is not matched with the increased first reference value, the particulate matter content on the air outlet side of the dust collection unit is monitored. If local air quality is better, the particulate matter content in the air is lower, and first benchmark is lower, and when the particulate matter content of the air inlet side and the first benchmark after reducing did not match, the particulate matter content of the air outlet side of monitoring dust collecting unit. This kind of scheme can avoid the air intake of dust collecting unit to be blockked up the time, influences the situation to the judgement of whether dust collecting unit needs the clearance.
As another example, in implementation, the content of particulate matter on the air outlet side of the dust collecting unit is monitored, when the content of particulate matter on the air outlet side exceeds the threshold range of the second reference value, the content of particulate matter on the air inlet side of the dust collecting unit is subjected to supplementary detection, the current dust collecting efficiency of the dust collecting unit in the current period is determined according to the content of particulate matter on the air outlet side and the content of particulate matter on the air inlet side, if the current dust collecting efficiency is not matched with the threshold range of the preset efficiency, it is determined that the dust collecting unit needs to be cleaned, and then self-cleaning or a prompt message is pushed to a user to prompt the cleaning or replacement of the dust collecting unit.
Use this kind of embodiment, contain higher particulate matter content when the outside air, collection dirt module normal operating, but because the air quality of air-out side is high, particulate matter content is lower, even the normal filtration that the air conditioner sent also will improve indoor particulate matter content through collection dirt module, this kind of condition only judges according to the benchmark value and leads to the error great easily, through benchmark value and two references of efficiency of predetermineeing the collection dirt degree of dust collection unit, can reduce the influence that environmental factor need the clearance to judging dust collection unit. And when the content of the particulate matters on the air outlet side does not exceed the reference value, the air supply meets the requirement, other calculation is not needed, and only the content of the particulate matters on the air outlet side of the dust collecting unit needs to be monitored in real time, so that the operation burden of the air conditioner is reduced.
Optionally, after determining the current dust collecting efficiency of the dust collecting unit in the current cycle, the method further comprises:
s31, determining the accumulated period number corresponding to the current period;
s32, judging whether the accumulated periodicity reaches the preset periodicity;
s33, if the cumulative cycle number corresponding to the current cycle reaches the preset cycle number, judging whether the cycle number of the cumulative cycle with which the dust collection efficiency is not matched with the preset efficiency is more than or equal to the preset number;
and S34, determining that the dust collecting unit needs to be cleaned.
It can be understood that, if the dust collecting condition of the dust collecting unit is judged according to the data of a single period, the judgment may be inaccurate, and the dust collecting condition of the dust collecting unit can also be comprehensively judged by adopting the data of multiple periods in the embodiment of the disclosure. Detecting the content of first particles in each period during implementation, starting multi-period nuclear detection after the first particle content and the reference value are not matched and the dust collection efficiency and the preset efficiency are not matched when the first particle content and the reference value are not matched and the two conditions that the dust collection efficiency and the preset efficiency are not matched are met for the first time, carrying out period counting on the current period, continuously operating the multi-period, determining the accumulated period number corresponding to the current period when the dust collection efficiency and the preset efficiency are not matched in each detection, judging whether the accumulated period number reaches the preset period number or not, and continuing the nuclear detection if the accumulated period number corresponding to the current period does not reach the preset period number; if the accumulated period number corresponding to the current period reaches the preset period number and the period number (the next called unmatched period number) with the dust collection efficiency unmatched with the preset efficiency in the accumulated period is larger than or equal to the preset number, the unmatched phenomenon can be determined to be accurately detected for the first time, and the dust collection unit is determined to be required to be cleaned.
In the case of performing the nuclear test, the process may be returned to step S01 as shown in fig. 3, or the process may be started from step S35 to monitor the first particulate matter content and the second particulate matter content of the dust collection module as shown in fig. 4.
In addition, the preset times can be set according to requirements. If the preset period number is 6, when the dust collecting unit needs to be accurately reminded of cleaning, the preset period number can be set to be a numerical value close to the preset period number, such as 5 or 6; when the dust collecting unit needs to be reminded to clean in advance, the preset number of times can be set to be about half of the preset number of cycles, such as 3 or 4; the preset number of times may be set to a small value, such as 2, when it is required that the dust collecting unit maintains a relatively clean state.
As an example, the precise reminding mode is adopted, and in implementation, the preset number of cycles is set to be 6, and the preset number of times is set to be 5. When two mismatch conditions are met for the first time, multi-cycle checking is started, the current cycle number is marked as 1, a plurality of cycles are continuously operated, the cycle where the current cycle number meets the two mismatch conditions (hereinafter referred to as a mismatch cycle) is respectively counted, when the mismatch cycle occurs, whether the accumulated cycle number corresponding to the current cycle number reaches a preset cycle number 6 is judged, if the accumulated cycle number corresponding to the current cycle number is larger than or equal to the preset cycle number 6, the mismatch cycle number in the accumulated cycle number is determined, and if the mismatch cycle number is larger than or equal to the preset cycle number 5, the dust collecting unit is determined to be required to be cleaned.
As another example, the cleaning mode is adopted, and in implementation, the preset number of cycles is set to be 5, and the preset number of cycles is set to be 2. When the two mismatch conditions are met for the first time, multi-cycle checking is started, the current cycle number is marked as 0, a plurality of cycles are continuously operated, the cycle where the current cycle number is located and the mismatch cycle number are respectively counted, when the mismatch cycle number occurs, whether the accumulated cycle number corresponding to the current cycle number reaches a preset cycle number 5 or not is judged, if the accumulated cycle number corresponding to the current cycle number is larger than or equal to the preset cycle number 5, the mismatch cycle number in the accumulated cycle number is determined, and if the mismatch cycle number is larger than or equal to the preset cycle number 2, the dust collection unit is determined to be required to be cleaned.
Optionally, the method for cleaning a dust collection unit further comprises:
s36, if the cumulative cycle number corresponding to the current cycle reaches the preset cycle number and the cycle number of the cumulative cycle with the dust collection efficiency not matched with the preset efficiency is less than the preset number, the cumulative cycle number and the dust collection efficiency of each cumulative cycle are cleared.
It can be understood that if the accumulated number of cycles corresponding to the current cycle reaches the preset number of cycles and the number of mismatched cycles is less than the preset number of cycles, the dust collecting unit is determined not to be required to be cleaned, and the phenomenon of mismatch is detected for the first time may be caused by an error, and the data is cleared.
