The running data of the existing household appliance can be directly utilized to analyze and judge the dirty and blocked conditions, so that the dirty and blocked detection can be quickly realized without increasing the cost, and the monitoring efficiency of the dirty and blocked state in the household appliance is improved.
It should be noted that the method for monitoring filth blockage of a home appliance provided in the embodiment of the present application may be executed by a home appliance, and accordingly, the filth blockage monitoring apparatus of a home appliance is generally disposed in a home appliance.
Based on the above description, the method for monitoring filth blockage of a home appliance according to the embodiment of the present application will be described in detail with reference to fig. 2:
referring to fig. 2, a flowchart of a filth blockage monitoring method for a home appliance in the embodiment of the present application is shown, where the method may be performed by a filth blockage monitoring apparatus of a home appliance, where a blower is disposed in the home appliance, and the method may include steps 220 to 240:
in step 220, an actual electric control parameter for the fan is obtained, and the actual electric control parameter is used for adjusting the fan to output a set rotating speed.
In this application, the rotational speed of fan and the dirty stifled degree of the household electrical appliances of fan place are deciding the actual automatically controlled parameter of fan jointly, wherein, if the rotational speed of fan is certain, the dirty stifled degree of the household electrical appliances of fan place is different, is directed against the actual automatically controlled parameter of fan is also different. The principle of the method is that under the condition that the rotating speed of the fan is certain, the dirty degree of household electrical appliances where the fan is located is different, the torque required by the rotation of the fan is different, and the actual electric control parameters of the fan are different.
It should be noted that, because the fan is located inside the household electrical appliance, if the degree of contamination of the household electrical appliance is higher, the space formed inside the household electrical appliance is more closed, which makes the required torque of the fan smaller under the condition of a certain rotational speed of the fan.
In the present application, the parameter type of the actual electrical control parameter for the fan may be determined according to the specific type of the fan. Specifically, if the fan is a dc fan driven by a dc motor, the actual electrical control parameter for the fan may include a VSP regulation voltage for the dc fan. If the fan is an ac fan driven by an ac motor, the actual electrical control parameter for the fan may include a chopping cycle for adjusting a voltage of the ac fan.
In order to make the control principle for dc fans and ac fans better understood by a person skilled in the art. This will be described below with reference to fig. 3 and 4, respectively.
Referring to fig. 3, a working principle diagram of the household appliance when the fan is a dc fan in the embodiment of the present application is shown.
For the dc fan, as shown in fig. 3, when the power voltage input to the rectification circuit 302 is constant, the control device MCU301 adjusts the VSP regulation voltage of the dc fan 303 to further adjust the rotation speed of the fan, so as to finally make the rotation speed of the fan reach the set rotation speed, where, when the set rotation speed of the dc fan is constant, if the required torque output by the dc fan is smaller, the VSP regulation voltage for adjusting the dc fan 303 is smaller, and if the required torque output by the dc fan is larger, the VSP regulation voltage for adjusting the dc fan 303 is larger.
It can be understood that, when the fan is a dc fan, if the VSP regulation voltage for regulating the dc fan 303 is smaller, the smaller the required torque output by the dc fan is, and further, the worse the dirty blockage degree of the household electrical appliance is.
Referring to fig. 4, a working principle diagram of the household appliance when the fan is an ac fan in the embodiment of the present application is shown.
As shown in fig. 4, when the power supply voltage input to the rectifier circuit 402 is constant, the control device PI401 adjusts the chopping period for the ac fan 403, and further adjusts the rotation speed of the fan, so as to finally make the rotation speed of the fan reach the set rotation speed, where when the set rotation speed of the ac fan is constant, the smaller the required torque output by the ac fan, the larger the chopping period for the ac fan 403 is adjusted, and the larger the required torque output by the ac fan, the smaller the chopping period for the ac fan 403 is adjusted.
It can be understood that, when the fan is an ac fan, if the chopping period for adjusting the ac fan 403 is larger, the smaller the required torque output by the ac fan is, and further, the more serious the dirty degree of the household electrical appliance is.
In step 240, actual filth blockage reference data is determined based on the actual electrical control parameter, and the actual filth blockage reference data is used for representing the actual filth blockage degree in the household appliance.
In an embodiment of the present application, the determining of the actual filth blockage reference data based on the actual electrical control parameter may be performed according to the following steps 1 to 2:
step 1, acquiring the corresponding relation between the filth blockage reference data and the electric control parameter under the set rotating speed output by the fan.
And 2, determining actual filth blockage reference data corresponding to the actual electric control parameters based on the corresponding relation.
In an embodiment of the application, the filth blockage reference data may include a filth blockage value, and the corresponding relationship may be a linear corresponding relationship between the filth blockage value and the electric control parameter at the set rotation speed output by the fan.
Further, the determining of the actual filth blockage reference data corresponding to the actual electronic control parameter based on the corresponding relationship may be performed according to the following steps:
and determining an actual filth blockage value corresponding to the actual electric control parameter based on the linear corresponding relation.
In this embodiment, a functional relationship (i.e., a corresponding relationship) between the filth blockage value and the electrical control parameter may be established for each set rotational speed, so that an actual filth blockage value corresponding to the actual electrical control parameter may be directly determined according to the functional relationship.
It can be understood that the actual filth level can be used to characterize the actual filth level in the home appliance, i.e. a higher actual filth level indicates a higher actual filth level in the home appliance.
Taking an air conditioner internal unit as an example, if a fan of the air conditioner internal unit is a direct current fan, based on the description of the direct current fan in fig. 3, it can be known that the functional relationship between the dirty block value and the VSP regulation voltage may be a negative correlation relationship. If the blower of the air conditioner internal unit is an ac blower, based on the description of the ac blower in fig. 4, the functional relationship between the dirty value and the chopping period may be a positive correlation.
In this application, based on dirty stifled value and automatically controlled parameter linear corresponding relation under the fan output settlement rotational speed confirm with the actual dirty stifled reference data that actual automatically controlled parameter corresponds, its benefit lies in, can directly utilize the actual automatically controlled parameter of current household electrical appliances to block up the reference data fast to the actual dirty stifled of household electrical appliances (be dirty stifled value), from and then can improve the monitoring efficiency to the dirty stifled state in the household electrical appliances.
In another embodiment of the present application, the filth blockage reference data may include a plurality of filth blockage tags, and the correspondence may be a correspondence between the plurality of filth blockage tags and a plurality of electric control parameter ranges at the set rotation speed output by the fan.
Further, the determining of the actual filth blockage reference data corresponding to the actual electronic control parameter based on the corresponding relationship may be performed according to the following steps 1 to 2:
step 1, determining the actual electric control parameter range to which the actual electric control parameter belongs.
And 2, determining an actual filth blockage label corresponding to the actual electric control parameter range based on the corresponding relation between the filth blockage labels and the electric control parameter ranges under the set rotating speed output by the fan.
In this embodiment, the plurality of visceral tags includes a severe visceral tag, a light visceral tag, and a no visceral tag.
Further, the severe filth blockage label, the slight filth blockage label and the no filth blockage label can respectively correspond to an electric control parameter range. If the actual electric control parameter belongs to an electric control parameter range corresponding to the severe filth blockage label, determining a severe filth blockage label for the household appliance, if the actual electric control parameter belongs to an electric control parameter range corresponding to the slight filth blockage label, determining a slight filth blockage label for the household appliance, and if the actual electric control parameter belongs to an electric control parameter range corresponding to the filth blockage-free label, determining a filth blockage-free label for the household appliance.
In order to make the person skilled in the art better understand the present embodiment, the following description will proceed with an air conditioner internal unit as an example, in terms of the fan being a dc fan and the fan being an ac fan.
Where the wind turbine comprises a dc wind turbine, the electrically controlled parameter may comprise a VSP regulation voltage for the dc wind turbine.
Further, the actual dirty label corresponding to the actual electrically controlled parameter range is determined based on the corresponding relationship between the dirty labels and the electrically controlled parameter ranges at the set rotating speed output by the fan, and the actual dirty label corresponding to the actual electrically controlled parameter range can be processed according to the following three conditions:
first, if the actual VSP regulation voltage of the dc fan is less than the first VSP regulation voltage, it is determined that the actual dirty label of the home appliance is a severe dirty label.
Secondly, if the actual VSP regulation voltage of the direct current fan is greater than or equal to the first VSP regulation voltage and less than the second VSP regulation voltage, determining that the dirty label of the household appliance is a slight dirty label.
Thirdly, if the actual VSP regulated voltage of the direct current fan is greater than or equal to the second VSP regulated voltage, determining that the actual dirty label of the household appliance is a dirty-free label.
In the application, after the actual filth blockage reference data is determined based on the actual electric control parameter, the actual filth blockage reference data can be prompted to a user, so that the user can determine whether to clean a filter screen and an evaporator of the air conditioner according to the filth blockage degree of the air conditioner reflected by the actual filth blockage reference data.
Specifically, referring to fig. 5, a flowchart of a method for monitoring filth blockage of a home appliance when a fan is a dc fan in the embodiment of the present application is shown, and specifically includes steps 401 to 407.
And step 504, displaying and pushing a severe filth blockage prompt with the APP.
And step 506, displaying and APP pushing a slight filth blockage prompt.
And step 507, the air conditioner operates normally, and no dirty and blockage prompt is displayed and pushed by the APP.
Therefore, aiming at the condition that the fan in the air conditioner drives the wind wheel by the direct current motor, the output torque of the direct current motor changes under a set high wind rotating speed due to the input wind volume changes of the filter screen and the evaporator before and after the filter screen and the evaporator are dirty and blocked, the change of the torque reflects the VSP regulating voltage change of the motor, after the filter screen and the evaporator are dirty and blocked, according to the air duct output principle, at the moment, when the rotating speed is set, the driving torque of the motor is reduced, and the VSP regulating voltage synchronously reflected at the motor is reduced. Therefore, whether the filter screen and the evaporator of the air conditioner are dirty or not can be judged through the change condition of the VSP regulating voltage, and therefore a user is reminded of needing to clean the filter screen and the evaporator.
Where the fan comprises an ac fan, the electrically controlled parameter may comprise a chopping cycle for adjusting the voltage of the ac fan.
Further, the actual dirty label corresponding to the actual electrically controlled parameter range is determined based on the corresponding relationship between the dirty labels and the electrically controlled parameter ranges at the set rotating speed output by the fan, and the actual dirty label corresponding to the actual electrically controlled parameter range can be processed according to the following three conditions:
firstly, if the actual chopping period of the alternating current fan is greater than or equal to the first chopping period, determining that the actual dirty label of the household appliance is a serious dirty label.
Secondly, if the actual chopping period of the alternating current fan is smaller than the first chopping period and is larger than or equal to the second chopping period, determining that the actual dirty label of the household appliance is a slight dirty label.
Thirdly, if the actual chopping period of the alternating current fan is smaller than the second chopping period, determining that the actual dirty and blocked label of the household appliance is a dirty and blocked-free label.
Similarly, after the actual filth blockage reference data is determined based on the actual electric control parameter, the actual filth blockage reference data can be prompted to the user, so that the user can determine whether to clean the filter screen and the evaporator of the air conditioner according to the filth blockage degree of the air conditioner reflected by the actual filth blockage reference data.
Specifically, referring to fig. 6, a flowchart of a method for monitoring filth blockage of a home appliance when a fan is an ac fan in the embodiment of the present application is shown, and specifically includes steps 601 to 607.
And step 602, acquiring a severe filth blockage chopper voltage period T1 and a slight filth blockage chopper voltage period T2 corresponding to the rotating speed N and the power supply voltage U.
And step 604, displaying and pushing a severe filth blockage prompt with the APP.
And step 606, displaying and APP pushing a slight filth blockage prompt.
And step 607, the air conditioner operates normally, and a no-dirty and blockage prompt is displayed and pushed by the APP.
It can be seen that, in the case that the fan in the air conditioner drives the wind wheel by the alternating current motor, because the input wind volume changes before and after the filter screen and the evaporator are dirty and blocked, the output torque of the alternating current motor changes at a set high wind rotating speed, and the change of the torque reflects the change of the input voltage of the motor. Therefore, whether the filter screen and the evaporator of the air conditioner are dirty or not can be judged according to the chopping cycle change condition of the motor input adjusting end, and therefore a user is reminded of needing to clean the filter screen and the evaporator.
In the method, the actual filth blockage reference data used for representing the actual filth blockage degree in the household appliance can be determined through the actual electric control parameter aiming at the fan of the household appliance based on the obtained information. The running data of the existing household appliance can be directly utilized to analyze and judge the dirty and blocked conditions, so that the dirty and blocked detection can be quickly realized without increasing the cost, and the monitoring efficiency of the dirty and blocked state in the household appliance is improved
