Fig. 1 is a schematic structural view of a purifier shown according to an exemplary embodiment, and fig. 2 is a schematic sectional view a-a of a purifier shown according to an exemplary embodiment. As shown in fig. 1 and 2, when the purifier 100 is in a normal configuration, it may include a housing 1, a fan 2 located inside the housing 1, a filter element 3 located inside the housing 1, and an inlet 4 and an outlet 5 provided on the housing 1. When the purifier 100 is normally operated, external fluid can enter the interior of the housing 1 through the inlet 4 under the action of the fan 2. And is output from the outlet 5 through the fan 2 after being filtered by the filter element 3, thereby achieving the purpose of purification. Wherein the purifier 100 may include an air purifier and a water purifier, and the input from the inlet 4 may be air or liquid, which is not limited by the present disclosure.
The filter element 3 is an indispensable essential element for achieving the purification function of the purifier 100. However, during the assembly of the purifier 100, the filter cartridge 3 may not be assembled inside the purifier 100 due to carelessness of an assembler or instability of a production line; alternatively, a user may forget to deploy a new cartridge when replacing the cartridge. Therefore, in view of the above many situations where it may be forgotten to dispose a filter cartridge, it is necessary to perform a filter cartridge check for the purifier 100. As shown in fig. 3, a flow chart of a method for testing a filter cartridge according to an exemplary embodiment is shown, which can be applied to a purifier 100, and can include the following steps:
in step 301, an operating parameter of the motor at a rated power is obtained, wherein the operating parameter is related to a load borne by the motor.
In this embodiment, the fan 2 may comprise an open loop motor, the rotational speed of which is load dependent. For example, the main control chip of the purifier 100 may output a fixed voltage duty ratio to the open-loop motor, so that the motor drives the fan blades of the fan 2 to rotate at a rated power.
In the air purifier, when the filter element 3 is normally disposed, the propagation path of the air sucked by the fan 2 is: an inlet 4-a filter element 3-a fan 2-an outlet; when the purifier 100 is not equipped with the filter cartridge 3, the propagation path of the air sucked by the fan 2 is: inlet 4-fan 2-outlet. Here, it can be assumed that the fan 2 includes an airflow suction area and an airflow discharge area, and that the air entering from the inlet 4 always passes through the airflow suction area and then passes through the fan 2 itself, the airflow discharge area, and then is discharged.
Then, when the filter element 3 is not installed in the purifier 100, the airflow entering from the inlet 4 can be supplemented to the airflow suction area at any time, when the fan blades of the fan 2 rotate, the airflow in the airflow suction area needs to do work, the load borne by the motor is increased, the rotating speed of the motor is reduced, and the torque of the motor is increased; when the filter element 3 is normally disposed in the purifier 100, at the moment when the fan 2 discharges the airflow in the current airflow suction area, the external air is blocked by the filter element 3, so that the instantaneous pressure in the airflow suction area is reduced, the load borne by the motor is reduced, the rotating speed of the motor is increased, and the torque of the motor is reduced.
Thus, in one embodiment, the operating parameter may include motor speed, which is inversely related to the load experienced by the motor; and, the motor can record the motor speed, and feed back this motor speed to main control chip for main control chip is according to the motor speed received, confirms whether purifier 100 has installed filter core 3. In another embodiment, the operating parameter may include a motor torque that is positively correlated with a load experienced by the motor; therefore, the motor torque can be calculated according to the acquired motor speed and rated power, and whether the filter element 3 is installed in the purifier 100 can be further determined according to the motor torque.
In step 302, whether the purifier is provided with the filter element is determined according to the corresponding relation between the working parameters and the preset parameter range.
In the present embodiment, when the operating parameter is within the preset parameter range, the purifier 100 can be considered to be installed with the filter element 3; when the operating parameter is not within the preset rotation speed range, the purifier 100 can be considered as not being provided with the filter element 3.
In one embodiment, when the rotation speed of the motor is within a preset rotation speed range, the purifier 100 is determined to be installed with the filter element 3; and when the rotating speed of the motor is not in the preset rotating speed range, determining that the filter element 3 is not installed in the purifier 100. In another embodiment, when the motor torque is within a preset torque range, it is determined that the filter cartridge 3 is installed in the purifier 100; when the motor torque is not within the preset torque range, it is determined that the filter cartridge 3 is not installed in the purifier 100.
In the above embodiments, when it is detected that the filter element 3 is not installed in the purifier 100, an alarm message may be prompted, so that a user or a designer can know the detection result of the purifier 100 in time. The alarm information can be reminded in a flashing mode through an indicator light; or may be prompted by voice; or may be alerted by vibration of the body of the purifier 100. Of course, the indicator light may flash while performing voice reminding or body vibration, or a combination of other reminding manners may be also possible, which is not limited in this disclosure.
Further, can also acquire the surplus use amount of filter core 3, when the surplus use amount of filter core 3 is less than preset threshold value, the probability of user's renew cartridge increases, at this moment, can start the detection procedure to whether install filter core 3 in this disclosure to can avoid all detecting when starting clarifier 100 at every turn, be favorable to practicing thrift processing resources.
According to the embodiment, the difference of the load borne by the motor is analyzed when the filter element 3 exists or not, so that whether the filter element 3 is configured in the purifier 100 or not is determined according to the preset parameter range corresponding to any working parameter related to the load under the rated power, and the detection is performed by avoiding installing other sensor elements in the purifier 100, so that the production cost can be reduced on one hand, and the condition that the detection function is misjudged or lost due to the service life and damage condition of the sensor elements can be avoided on the other hand.
In order to facilitate the detailed explanation of the technical solution of the present disclosure, the following description will be made by means of specific implementation steps.
FIG. 4 is a flow chart illustrating another method of filter cartridge testing according to an exemplary embodiment. As shown in fig. 4, the detection method may include the steps of:
in step 401, the remaining usage of the filter cartridge 3 is acquired.
In the present embodiment, the remaining usage amount of the filter element 3 can be determined based on the relationship between the total time period from the time when the remaining usage amount of the filter element is 100% to the time when the filter element is exhausted, which is theoretically determined, and the actual used time period. For example, assuming that it is theoretically determined that the filter cartridge 3 can be used for 100 days and the filter cartridge 3 has been used for 98 days, the remaining usage amount of the filter cartridge 3 is 2%, and at this time, the probability of replacement of the purifier 100 by a user is high, so that it is necessary to check whether the purifier 100 is equipped with the filter cartridge 3 in order to avoid a situation where the user forgets to dispose the filter cartridge 3.
Of course, in other embodiments, the purification efficiency of the purifier can be determined according to the concentration of the pollutant before the air purification and the concentration of the pollutant after the air purification, so that the residual usage amount of the filter element 3 can be determined according to the purification efficiency. Alternatively, the remaining usage of the filter cartridge 3 may be determined in other manners, which is not limited by the present disclosure.
In step 402, it is determined whether the remaining usage is below a preset threshold.
In this embodiment, when the remaining usage amount of the filter element 3 is lower than the preset threshold, go to step 403; when the remaining usage of the filter cartridge 3 is higher than the preset threshold, the process proceeds to step 406. Wherein the preset threshold may be a percentage, such as 2% or 5%, etc., or the preset threshold may be the remaining number of days of use, such as 1 day, 2 days, etc., which is not limited by the present disclosure.
In step 403, the motor speed is obtained.
In this embodiment, under certain voltage duty ratio, the motor of fan 2 feeds back the motor speed to main control chip, avoids using other sensing element to detect, can reduction in production cost. For example, a counter inside the motor counts once every revolution of the motor, so that the motor speed can be determined from the number of revolutions and the time.
In step 404, it is determined whether the motor speed is within a preset speed range.
In the present embodiment, when the motor rotation speed is within the preset rotation speed range, step 403 is executed; when the motor speed is not within the preset speed range, step 404 is executed.
Wherein, the preset rotating speed range can be an interval consisting of two numerical values; or a range of intervals separated by a predetermined threshold, for example, the predetermined rotational speed range may be [ N1, N2], N1 < N2; alternatively, the preset rotation speed range may be [ N1, + ∞ ], and the disclosure is not limited thereto.
In step 405, when the motor rotation speed is within the preset rotation speed range, it is determined that the filter element is installed.
In the present embodiment, when it is determined that the filter cartridge is normally disposed inside the purifier 100, the purifier 100 can normally perform the air purifying operation.
In step 406, the purifier 100 is started
In step 407, when the motor rotation speed is not within the preset rotation speed range, it is determined that the filter cartridge is not installed.
In step 408, the indicator lights flash.
In this embodiment, when it is determined that the purifier 100 is not provided with the filter cartridge 3, the associated indicator lamp of the purifier 100 may blink to prompt the user that the purifier 100 is not currently provided with the filter cartridge. Of course, in other embodiments, the alarm may be generated by a voice alarm or vibration of the body of the purifier 100, which is not limited by the present disclosure.
It should be noted that: in the embodiment shown in fig. 4, the process of detecting the filter element is described by taking the rotation speed of the motor as an example, and in the practical application process, the filter element can be detected by twisting the motor, which is not described herein again.
