All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In order to facilitate self-cleaning of dust of an air conditioner heat exchanger, the application discloses an air conditioner self-cleaning method.
Specifically, referring to fig. 1, the self-cleaning method of the air conditioner disclosed in the embodiment of the present application may include steps S101 to S106.
Step S101: and acquiring the accumulated working time of the air conditioner from the last self-cleaning time to the current time of the air conditioner, and recording the accumulated working time as a first time.
In the step, when the air conditioner works, the working time of the air conditioner is measured in real time, the time is recorded as a first time, the starting time of the time is the last self-cleaning time of the air conditioner, namely, in the scheme, when the self-cleaning of the air conditioner is detected, the self-cleaning time is recorded, the accumulated working time and the accumulated standing time of the air conditioner are initialized, and the time is restarted.
Step S102: and acquiring the accumulated standing time length of the air conditioner from the last self-cleaning time to the current time of the air conditioner, and recording the accumulated standing time length as a second time length.
In the step, when the air conditioner stands still, the standing time of the air conditioner is measured in real time, the time is recorded as a second time, and the starting time of the time is the time of first shutdown after the last self-cleaning of the air conditioner is finished.
Step S103: the dust concentration of the environment in which the heat exchanger is located is obtained.
In this step, the dust concentration of the environment where the heat exchanger is located is obtained in real time, and the heat exchanger may be an inner and outer heat exchanger of an air conditioner. In the scheme, the dust concentration of the environment where the heat exchanger is located is measured in real time, and the dust concentration is in one-to-one correspondence with each moment so as to be used for calculating the dust accumulation in the subsequent process.
Step S104: and calculating the dust accumulation amount of the heat exchanger based on the dust concentration and the first time period and the second time period.
In the scheme, after the dust concentration is detected, if the air conditioner is in a working state, the dust accumulation amount of the heat exchanger when the air conditioner works is calculated in real time based on the first time length and the detected dust concentration. And if the air conditioner is in a standing state, calculating the dust accumulation amount of the heat exchanger when the air conditioner stands in real time based on the second time length and the detected dust concentration in time. And taking the sum of the two calculated dust accumulation amounts as the total dust accumulation amount of the air conditioner.
Step S105: judging whether the dust accumulation amount is larger than a preset dust amount.
In this scheme, a preset dust amount is preset, and when the dust accumulation amount calculated in step S104 is greater than the preset dust amount, it indicates that excessive dust accumulation on the heat exchanger needs to be cleaned, so that it needs to be determined whether the dust accumulation amount is greater than the preset dust amount.

In the step, when the need of cleaning the heat exchanger is determined, an air conditioner self-cleaning instruction is generated, and the air conditioner self-cleaning instruction is used for controlling the air conditioner to execute a self-cleaning function to clean the heat exchanger.
According to the self-cleaning method for the air conditioner, the dust concentration of the environment where the heat exchanger is located is obtained by measuring the accumulated working time length of the air conditioner and the accumulated standing time length of the air conditioner, the dust accumulation amount of the air conditioner in the working and standing states is calculated based on the working time length, the standing time length and the dust concentration, and when the air conditioner is judged to be required to be cleaned based on the calculated dust accumulation amount, the air conditioner is controlled to execute the self-cleaning function, so that the self-cleaning of the air conditioner is realized, and the cleaning process is not required to be interfered by a user.
In another embodiment of the present application, the calculating, based on the dust concentration and the first duration and the second duration, the dust accumulation amount of the heat exchanger specifically includes:

In this embodiment, when calculating the first dust accumulation amount and the second dust accumulation amount, the calculation may be performed in an integral manner, and specifically, the process of calculating the first dust accumulation amount includes: when the air conditioner works, integrating the dust concentration detected when the air conditioner works based on the increasing speed of the first time length to obtain a first dust accumulation amount; the process of calculating the second dust accumulation amount is specifically: and when the air conditioner is kept still, integrating the dust concentration detected when the air conditioner is kept still based on the increasing speed of the second time period to obtain a second dust accumulation amount.
Specifically, q= ≡based t1 n+A∫ t2 And calculating n to obtain the dust accumulation amount of the heat exchanger, wherein t1 is a first duration, t2 is a second duration, A is a correction coefficient, and n is the measured dust concentration of the environment where the heat exchanger is located. Substituting the measured first time period, second time period, dust concentration, and correction coefficient into the formula q= ≡ t1 n+A∫ t2 n is calculated to obtain the dust accumulation amount of the heat exchanger.
In the technical solution disclosed in the embodiments of the present application, if the air conditioner is a newly installed air conditioner, the last self-cleaning time of the air conditioner cannot be detected in step S101, so in the above solution, the time when the computer board of the air conditioner is powered on for the first time may be replaced with the last self-cleaning time of the air conditioner, and in the above solution, when the last self-cleaning time of the air conditioner is not detected, the cumulative working time of the air conditioner from the last self-cleaning time of the air conditioner to the current time is obtained, including: acquiring accumulated working time of the air conditioner from the first power-on of the air conditioner computer board to the current moment; the method for obtaining the accumulated standing time length of the air conditioner from the last self-cleaning time to the current time of the air conditioner comprises the following steps: and acquiring the accumulated standing time length of the air conditioner from the first power-on of the air conditioner computer board to the current moment.
