Disclosure of Invention
In order to solve the above problems in the prior art, that is, to solve the problem that the conventional air conditioner is easy to frequently execute a self-cleaning mode due to misjudgment by judging a single condition of a fan current of an indoor unit, the present invention provides a self-cleaning control method for an air conditioner, the air conditioner comprises an indoor unit, the self-cleaning control method comprises: acquiring the current average value in the current month and the current average value in the previous month of a fan of an indoor unit when the air conditioner is in heating operation; and judging whether to execute a self-cleaning mode on the indoor unit according to the current average value in the current month and the current average value in the previous month.
In the preferred technical solution of the self-cleaning control method, the step of determining whether to execute the self-cleaning mode on the indoor unit according to the current average value in the current month and the current average value in the previous month comprises: 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 preset value; and judging whether to execute a self-cleaning mode on the indoor unit or not according to the comparison result.
In a preferred embodiment of the above self-cleaning control method, the step of determining whether to execute the self-cleaning mode on the indoor unit according to the comparison result includes: 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 greater than a preset value, executing a self-cleaning mode on the indoor unit.
In a preferred embodiment of the above self-cleaning control method, the step of determining whether to execute the self-cleaning mode on the indoor unit according to the comparison result further includes: 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 preset value, not executing the self-cleaning mode on the indoor unit.
In a preferred embodiment of the above self-cleaning control method, the step of determining whether to execute the self-cleaning mode on the indoor unit according to the current average value in the current 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 in the current month relative to the current average value in the previous month with the preset value reach the preset times, executing a self-cleaning mode on the indoor unit.
In the preferable technical scheme of the self-cleaning control method, the preset times are 5 times.
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 set time, executing a self-cleaning mode on the indoor unit.
In a preferred technical solution of the above self-cleaning control method, the set time is 10 hours.
In another aspect, the present invention also provides an air conditioner including a controller configured to be capable of performing the above-described self-cleaning control method.
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 is compared with the current average value in the previous month, and then it is determined whether to perform the self-cleaning mode on the indoor unit according to the comparison result.

Further, the present invention provides another control method, that is, when the number of execution times of the step of comparing the attenuation value of the current average value of the current in the current month with the current average value of the previous month with the preset value reaches the preset number of times, the self-cleaning mode is executed to the indoor unit, so that the indoor unit is cleaned. By the control mode, when the fan of the indoor unit is in failure/is detected to have deviation so that the current is not reduced 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 preset value, and the situation that the self-cleaning mode is not executed all the time because the air conditioner cannot meet the condition 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 preset value is avoided.
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 set time or not, and through the control mode, when the current of the fan of the indoor unit is detected to be in failure, 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 through the first control mode and the second control mode is avoided.
In addition, the air conditioner further provided by the invention on the basis of the technical scheme has the technical effect of the self-cleaning control method due to the adoption of the self-cleaning control method, and compared with the existing air conditioner, the air conditioner can prevent the situation that the air conditioner frequently executes the self-cleaning mode due to the misjudgment caused by the fluctuation of the current of the fan of the indoor unit.

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 and the 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: acquiring the current average value in the current month and the current average value in the previous month of a fan of an indoor unit when the air conditioner is in heating operation; and judging whether to execute a self-cleaning mode on the indoor unit according to the current average value in the current month and the current average value in the previous month. 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.
Preferably, as shown in fig. 2, the step of determining whether to perform the self-cleaning mode on the indoor unit according to the current average value of the current in the current month and the current average value of the current 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 preset value; and judging whether to execute a self-cleaning mode on the indoor unit or not according to the comparison result. 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 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 preset value, not executing the self-cleaning mode on the indoor unit.
It should be noted that, in the above embodiment, the preset value may be 0.1A, which is not limited, and a person skilled in the art may flexibly set a specific value of the preset value in practical application, as long as whether the fan current of the indoor unit is greatly attenuated due to the dust deposition is judged by the preset value.
Preferably, the step of determining whether to perform the self-cleaning mode on the indoor unit according to the current average value in the current 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 in the current month relative to the current average value in the previous month with the preset value reach the 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 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.
Further, the air conditioner of the present invention further includes a controller configured to be able to perform the above-described self-cleaning control method. Namely, the controller can prevent the air conditioner from the condition that the air conditioner frequently executes the self-cleaning mode due to the misjudgment caused by the fluctuation of the current of the fan of the indoor unit.
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.
