In a preferred technical solution of the above self-cleaning control method, the self-cleaning control method further includes: and if the running time of the air conditioner reaches the preset time, executing a self-cleaning mode on the indoor unit.
As can be understood by those skilled in the art, in a preferred embodiment of the present invention, when the air conditioner is in heating operation, the current average value in the current month and the current average value in the previous month are compared, and then whether to perform the self-cleaning mode on the indoor unit is determined according to the comparison result. Compared with the technical scheme of comparing the real-time current of the fan of the indoor unit with the preset value in the prior art, the method and the device can not greatly reduce the average current value even if the fan current of the indoor unit fluctuates accidentally, so that the air conditioner cannot be subjected to the condition that the air conditioner frequently executes the self-cleaning mode due to misjudgment caused by the fluctuation of the fan current of the indoor unit.
Furthermore, when the air conditioner judges, the average current value in the month can be judged firstly, and then the real-time current value can be judged; or the real-time current value can be judged first, and then the current average value in the month can be judged. The skilled person can flexibly set the above-mentioned determination steps in practical applications, as long as it can be determined whether to execute the self-cleaning mode on the indoor unit of the air conditioner by the current average value and the real-time current value in this month.
Furthermore, on the basis of the control mode, the invention also provides another control mode, namely when the current average value in the current month is judged firstly and then the real-time current value is judged, if the execution times of the step of comparing the attenuation value of the current average value in the current month relative to the current average value in the previous month with the first preset value reach the first preset times, the self-cleaning mode is executed on the indoor unit; when the real-time current value is judged firstly and then the current average value in the current month is judged, if the execution times of the step of comparing the attenuation value of the real-time current value relative to the current average value in the previous month with the second preset value reach the second preset times, the self-cleaning mode is executed on the indoor unit. By the control mode, when the fan of the indoor unit is in fault/deviation in detection to enable the current not to drop all the time, the air conditioner can still judge the time for entering the self-cleaning mode by calculating the execution times of the step of comparing the attenuation value of the current average value of the current month relative to the current average value of the previous month with the first preset value or comparing the attenuation value of the real-time current value relative to the current average value of the previous month with the second preset value, and the situation that the self-cleaning mode is not executed all the time due to the fact that the air conditioner cannot meet the conditions that the attenuation value of the current average value of the current month relative to the current average value of the previous month is larger than the first preset value and the attenuation value of the real-time current value relative to the current average value.
Furthermore, on the basis of the two control modes, the invention further provides a control mode for judging whether to execute the self-cleaning mode or not by judging whether the running time of the air conditioner reaches the preset time or not, and by the control mode, when the current of the fan of the indoor unit is detected to be in fault, the opportunity of entering the self-cleaning mode can still be judged by the running time of the air conditioner, so that the situation that the self-cleaning mode is not executed all the time because the air conditioner cannot execute the self-cleaning mode by the first control mode and the second control mode is avoided.

Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. For example, although the present invention has been described with reference to an indoor unit of an air conditioner, since the indoor unit and the outdoor unit of the air conditioner have a symmetrical structure, the principle of the present invention is also applicable to the case where the outdoor unit performs self-cleaning during cooling operation of the air conditioner, and at this time, the fan current of the indoor unit in the determination condition is replaced with the fan current of the outdoor unit.
The problem that the existing air conditioner frequently executes the self-cleaning mode due to misjudgment is easily caused by judging the single condition of the current of the fan of the indoor unit based on the background technology. The invention provides a self-cleaning control method for an air conditioner, aiming at preventing the air conditioner from frequently executing a self-cleaning mode due to misjudgment caused by the fluctuation of the current of a fan of an indoor unit.
Specifically, the air conditioner of the present invention includes an indoor unit, and as shown in fig. 1, the self-cleaning control method of the present invention includes: when the air conditioner is in heating operation, acquiring a real-time current value, a current average value in the current month and a current average value in the previous month of a fan of an indoor unit; and judging whether to execute a self-cleaning mode on the indoor unit or not according to the real-time current value, the current average value in the current month and the current average value in the previous month. In practical application, the average current value in the month can be judged firstly, and then the real-time current value can be judged; or the real-time current value can be judged firstly, and then the current average value in the month can be judged; and the real-time current value of the current average value in the month can be judged at the same time. It should be noted that the current of the fan of the indoor unit can directly reflect the dust deposition degree of the air conditioner, because the load of the fan is determined at a certain rotation speed, when the load of the fan is increased at the same rotation speed, and accordingly, the current of the fan is decreased, it is indicated that the wind resistance of the fan is increased, that is, the dust deposition on the indoor unit is performed, and the more serious the dust deposition is, the smaller the current of the fan is, so the dust deposition degree of the indoor unit of the air conditioner can be fully determined according to the current of the fan. The technical solution of the present invention is explained in detail below with reference to two examples.
Example one
As shown in fig. 2, the step of determining whether to execute the self-cleaning mode on the indoor unit according to the real-time current value, the current average value in the current month, and the current average value in the previous month includes: comparing the attenuation value of the current average value of the current month relative to the current average value of the current of the previous month with a first preset value; if the attenuation value of the current average value in the current month relative to the current average value in the previous month is greater than the first preset value, comparing the attenuation value of the real-time current value relative to the current average value in the previous month with a second preset value; and judging whether to execute a self-cleaning mode on the indoor unit or not according to the comparison result. And if the attenuation value of the current average value in the current month relative to the current average value in the previous month is not greater than the first preset value, not executing the self-cleaning mode on the indoor unit. The step of judging whether to execute the self-cleaning mode to the indoor unit according to the comparison result comprises the following steps: if the attenuation value of the real-time current value relative to the current average value in the previous month is greater than a second preset value, a self-cleaning mode is executed on the indoor unit; and if the attenuation value of the real-time current value relative to the current average value in the previous month is not greater than a second preset value, not executing the self-cleaning mode on the indoor unit.
Example two
The step of judging whether to execute the self-cleaning mode on the indoor unit according to the real-time current value, the current average value in the current month and the current average value in the previous month comprises the following steps: comparing the attenuation value of the real-time current value relative to the current average value of the previous month with a second preset value; if the attenuation value of the real-time current value relative to the current average value in the previous month is greater than a second preset value, comparing the attenuation value of the current average value in the current month relative to the current average value in the previous month with a first preset value; and judging whether to execute a self-cleaning mode on the indoor unit or not according to the comparison result. And if the attenuation value of the real-time current value relative to the current average value in the previous month is not greater than a second preset value, not executing the self-cleaning mode on the indoor unit. The step of judging whether to execute the self-cleaning mode to the indoor unit according to the comparison result comprises the following steps: if the attenuation value of the current average value in the current month relative to the current average value in the previous month is larger than a first preset value, a self-cleaning mode is executed on the indoor unit; and if the attenuation value of the current average value in the current month relative to the current average value in the previous month is not greater than the first preset value, not executing the self-cleaning mode on the indoor unit.
It should be noted that, in the two embodiments described above, the first preset value may be 0.1A, and the second preset value may also be 0.1A, which is not limiting, and a person skilled in the art may flexibly set specific values of the first preset value and the second preset value in practical application, as long as whether the fan current of the indoor unit is greatly attenuated due to dust deposition is determined by the first preset value and the second preset value.
Preferably, the step of determining whether to execute the self-cleaning mode on the indoor unit according to the real-time current value, the current average value in this month, and the current average value in the previous month further includes: and if the execution times of the step of comparing the attenuation value of the current average value of the current in the current month relative to the current average value of the previous month with the first preset value reach the first preset times, executing a self-cleaning mode on the indoor unit. The preset times can be set by a person skilled in the art through an experimental manner, or can be set through an empirical manner, as long as the air conditioner can execute the self-cleaning mode through the demarcation point determined by the preset times. For example, the preset number of times may be 5, that is, when the number of times of performing the step of "comparing the attenuation value of the current average value of the present month with respect to the current average value of the previous month with the first preset value" reaches 5, the air conditioner immediately and automatically performs the self-cleaning mode.
Preferably, the step of determining whether to execute the self-cleaning mode on the indoor unit according to the real-time current value, the current average value in this month, and the current average value in the previous month further includes: and if the execution times of the step of comparing the attenuation value of the real-time current value relative to the current average value in the previous month with the second preset value reach the second preset times, executing a self-cleaning mode on the indoor unit. The preset times can be set by a person skilled in the art through an experimental manner, or can be set through an empirical manner, as long as the air conditioner can execute the self-cleaning mode through the demarcation point determined by the preset times. For example, the preset number of times may be 5, that is, when the number of times of performing the step of "comparing the attenuation value of the real-time current value with respect to the current average value of the last month with the second preset value" reaches 5, the air conditioner immediately and automatically performs the self-cleaning mode.
Preferably, the self-cleaning control method of the present invention further comprises: and if the running time of the air conditioner reaches the set time, executing a self-cleaning mode on the indoor unit. The setting time may be set experimentally or empirically by a person skilled in the art, as long as the air conditioner can execute the self-cleaning mode through the demarcation point determined by the setting time. For example, the set time may be 10h (hours), that is, when the operation time of the air conditioner reaches 10h, the air conditioner automatically performs the self-cleaning mode immediately.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
