For this reason, the prior art has completed self-cleaning of the air conditioner by controlling the heat exchanger to perform frosting and defrosting processes, respectively.
In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in the related art:

Currently, air conditioning is increasingly important in the home life. However, if the air conditioner is not cleaned in time after being used for a long time, a lot of dust is accumulated on the heat exchanger of the air conditioner, and meanwhile, bacteria are also bred. This clearly poses a great threat to human health. For this reason, the prior art mainly completes self-cleaning of the air conditioner by controlling frosting and defrosting of the heat exchanger. When the outdoor heat exchanger is self-cleaned, the air conditioner performs a heating cycle in a frost stage. However, the time of the frost stage is often longer, so that the self-cleaning process can influence the indoor temperature in high-temperature environments such as summer, and especially the comfort of a user can be damaged by hot air blown out by an indoor fan. However, the direct closing of the indoor fan can cause the pressure difference of the refrigerant of the air conditioner to be reduced, which is not beneficial to the rapid frosting of the outdoor heat exchanger.
Referring to fig. 1, an embodiment of the present disclosure provides a method for self-cleaning an air conditioner, including:
S101, under the condition that a frost condensation stage is entered, the air conditioner executes a heating cycle, and the outdoor heat exchanger starts to condense frost.
S102, the air conditioner continuously detects the temperature of the outdoor coil.
S103, the air conditioner controls the indoor fan to intermittently start and stop according to the temperature of the outdoor coil, so as to assist the outdoor heat exchanger in frosting.
By adopting the method for self-cleaning the air conditioner, which is provided by the embodiment of the disclosure, the outdoor heat exchanger can be quickly cooled by controlling the air conditioner to execute heating circulation in the frost condensation stage. Thereby being beneficial to condensing the water flowing through the outdoor heat exchanger into frost and wrapping the dust and dirt on the surface of the outdoor heat exchanger so as to remove the dust and dirt together in the defrosting stage. Meanwhile, the temperature of the outdoor coil is continuously detected and the intermittent start and stop of the indoor fan are controlled in the frost condensation stage, so that the indoor fan can be prevented from being always started to have adverse effects on the indoor temperature. The intermittent start and stop of the fan can also accelerate the flow speed of water vapor in the air conditioner, and is beneficial to the rapid frosting of the outdoor heat exchanger. Therefore, the embodiment of the disclosure can improve the comfort of the user on the premise of guaranteeing the frosting performance, and further improve the actual use experience of the user.
Optionally, the air conditioner outdoor unit is provided with an outdoor coil temperature sensor. The temperature of the outdoor coil of the air conditioner can be obtained in real time or periodically, and the control of the running rotating speed of the indoor fan is facilitated.
Optionally, the air conditioner controls the intermittent start and stop of the indoor fan according to the temperature of the outdoor coil, and the air conditioner comprises: the air conditioner determines the running rotating speed of the indoor fan according to the temperature of the outdoor coil pipe every first time length; the air conditioner controls the indoor fan to operate at the operation rotating speed, and stops operating after the second time duration. Wherein, the sum of the first time length and the second time length is a start-stop period. Thus, the air conditioner can periodically start and stop the indoor fan. Specifically, in the first half of a start-stop period, the air conditioner determines the operating speed of the indoor fan according to the temperature of the outdoor coil, and executes the operating speed for a second period of time. And in the latter half of the start-stop period, the air conditioner controls the indoor fan to stop running for a first duration. Thus, the intermittent start and stop of the indoor fan can avoid the adverse effect on the indoor temperature caused by the fact that the indoor fan is always started. The flow speed of water vapor in the air conditioner can be accelerated, and the rapid frosting is facilitated. Therefore, the embodiment of the disclosure can improve the comfort of the user on the premise of ensuring the frosting performance, and further improve the actual use experience of the user.
Optionally, the first duration may be adjusted according to an actual operation condition of the air conditioner. Specifically, the first time period may be set to 30s, 60s, or 90s.
Optionally, the second duration may be adjusted according to an actual operation condition of the air conditioner. Specifically, the second time period may be set to 10s, 20s, or 30s.
Optionally, the start-stop period can be adjusted according to the actual running condition of the air conditioner. But it is necessary to ensure that the duration of one start-stop period is equal to the sum of the first duration and the second duration. Specifically, the start-stop period may be set to 40s, 80s, or 120s.
Optionally, the air conditioner determining the operation rotation speed of the indoor fan according to the temperature of the outdoor coil comprises: the air conditioner determines a target interval of the temperature of the outdoor coil; comparing the current outdoor coil temperature with a target interval by the air conditioner, and determining a rotating speed compensation value of the indoor fan; the air conditioner obtains the running rotating speed of the indoor fan determined in the last start-stop period, and adds the running rotating speed with the rotating speed compensation value to obtain the current running rotating speed of the indoor fan. Therefore, the air conditioner can continuously correct the running rotating speed of the indoor fan according to the temperature of the outdoor coil, so that the temperature of the outdoor coil gradually approaches to a target zone. Further, smooth frost condensation of the outdoor heat exchanger can be guaranteed, and self-cleaning effect of the air conditioner is improved.
Optionally, the air conditioner determining the target interval of the outdoor coil temperature includes: the air conditioner compares the current outdoor coil temperature with the outdoor coil temperature before a start-stop period to determine the increase and decrease conditions of the outdoor coil temperature; under the condition that the temperature of the outdoor coil is reduced, the air conditioner determines a target interval of the temperature of the outdoor coil as a first interval; in the case that the outdoor coil temperature is in an increase, the air conditioner determines a target zone of the outdoor coil temperature as a second zone. Thus, the air conditioner can reasonably adjust the value range of the target section according to the increasing and decreasing trend of the temperature of the outdoor coil. Therefore, the temperature of the outdoor coil pipe can be finely adjusted, so that the temperature of the outdoor coil pipe approaches to a reasonable temperature more quickly. Therefore, the embodiment of the disclosure is beneficial to accelerating the frost condensing speed of the outdoor heat exchanger, thereby improving the self-cleaning efficiency of the air conditioner.
Optionally, the first interval may be adjusted according to an actual operation condition of the air conditioner. Specifically, in some embodiments, the first interval may be set to [ -21 ℃, -17 ℃ ].
Optionally, the second interval may be adjusted according to an actual operation condition of the air conditioner. Specifically, in some embodiments, the second interval may be set to [ -19 ℃, -15 ℃ ].
Optionally, the air conditioner compares the current outdoor coil temperature with a target interval to determine a rotation speed compensation value of the indoor fan, including: under the condition that the current outdoor coil temperature belongs to a target interval, the air conditioner determines that the rotating speed compensation value of the indoor fan is zero; under the condition that the temperature of the current outdoor coil is greater than the upper limit value of the target interval, the air conditioner determines the rotating speed compensation value of the indoor fan as a first compensation value; and under the condition that the current temperature of the outdoor coil is smaller than the lower limit value of the target interval, the air conditioner determines the rotating speed compensation value of the indoor fan as a second compensation value. Thus, the air conditioner can determine a specific value of the rotation speed compensation value according to the relation between the current outdoor coil temperature and the target interval. Therefore, the rotating speed of the indoor fan can be corrected in a targeted manner, so that the temperature of the outdoor coil pipe can be adjusted, and the temperature of the outdoor coil pipe gradually approaches to a reasonable temperature.
Specifically, the first compensation value is a positive value, and the second compensation value is a negative value. Thus, if the current outdoor coil temperature is greater than the maximum temperature of the target zone, the determined first compensation value is a positive value. The running rotating speed of the indoor fan is controlled to be increased, so that the temperature of the outdoor coil pipe is reduced to approach a target interval. And when the current outdoor coil temperature is less than the minimum temperature of the target interval, the determined second compensation value is a negative value. The running rotating speed of the indoor fan is controlled to be reduced, so that the temperature of the outdoor coil pipe is increased to approach a target zone.
Optionally, the first compensation value and the second compensation value are opposite to each other. Therefore, the increase and decrease of the running rotating speed of the indoor fan can be kept consistent, and standardized control of the rotating speed of the fan is facilitated.
Optionally, the running speed of the indoor fan is set to be a legal speed interval. Specifically, the range of legal rotation speed interval is [ K1, K2]. When the current running rotating speed of the indoor fan is calculated to be larger than K2, the indoor fan is controlled to run according to the running rotating speed of K2. When the current running rotating speed of the indoor fan is less than K1, the indoor fan is controlled to run according to the running rotating speed of K1. In some embodiments, K1 may take on a value of zero. Therefore, the embodiment of the disclosure can ensure that the rotating speed of the indoor fan is always in a reasonable range, thereby improving the self-cleaning reliability of the air conditioner.

S206, under the condition that the current outdoor coil temperature is smaller than the lower limit value of the target interval, the air conditioner determines the rotating speed compensation value of the indoor fan to be a second compensation value.
S207, the air conditioner obtains the running rotating speed of the indoor fan determined in the last start-stop period, and adds the running rotating speed with the rotating speed compensation value to obtain the current running rotating speed of the indoor fan.

Meanwhile, the embodiment of the disclosure continuously detects the temperature of the outdoor coil pipe in the frost stage, and controls the intermittent start and stop of the indoor fan by taking the start and stop period as a unit. And when each start-stop period starts, the air conditioner determines the numerical value of the indoor fan rotating speed compensation value according to the relation between the current outdoor coil temperature and the target interval. And then periodically correcting the rotating speed of the indoor fan to adjust the temperature of the outdoor coil pipe so as to gradually approach to a reasonable temperature. And in the second half of the start-stop period, the indoor fan is controlled to stop running so as to avoid the adverse effect on the indoor temperature caused by the fact that the indoor fan is always started. Meanwhile, the intermittent start and stop of the fan can also accelerate the flow speed of water vapor in the air conditioner, and the outdoor heat exchanger is beneficial to rapid frosting. Therefore, the embodiment of the disclosure can improve the comfort of the user on the premise of guaranteeing the frosting performance, and further improve the actual use experience of the user.
