Next, taking the air conditioner 10 in fig. 1 as an execution main body, an exemplary description is given of an air conditioner self-cleaning control method according to an embodiment of the present invention with reference to a flowchart, specifically, fig. 2 is a flowchart of an air conditioner self-cleaning control method according to an embodiment of the present invention, and please refer to fig. 2, where the method includes:
step S20, under the condition that a shutdown instruction is received, acquiring indoor environment temperature and outdoor environment temperature;
optionally, the shutdown instruction is used to instruct the air conditioner to shutdown, where the shutdown instruction may be an instruction sent by a user through an intelligent terminal such as a remote controller or a mobile phone, or an instruction obtained when the air conditioner meets a preset shutdown condition.
In this embodiment, after obtaining the shutdown instruction, the air conditioner may send an ambient temperature request instruction to the indoor ambient temperature collection device and the outdoor ambient temperature collection device, respectively, so that the indoor ambient temperature collection device and the outdoor ambient temperature collection device send the indoor ambient temperature and the outdoor ambient temperature to the controller of the air conditioner when receiving the ambient temperature request instruction.
Step S21, determining whether the air conditioner meets a self-cleaning condition according to the indoor environment temperature and the outdoor environment temperature;
s22, controlling the communication module to acquire the environment humidity of the position where the air conditioner is located under the condition that the air conditioner meets the self-cleaning condition;
in a possible implementation manner, the air conditioner can automatically control the communication module to acquire the environmental humidity of the position where the air conditioner is located under the condition that the air conditioner determines that the air conditioner meets the self-cleaning condition; in another possible implementation manner, the air conditioner may send a prompt signal to a user to prompt the user that the air conditioner may perform self-cleaning when it is determined that the air conditioner satisfies a self-cleaning condition, and control the communication module to acquire the ambient humidity at the location where the air conditioner is located when a self-cleaning instruction sent by the user is received.
Optionally, the air conditioner may remind the user that the air conditioner may be currently self-cleaned by voice prompt, lighting of an indicator lamp, or prompt of an intelligent device or a remote controller. For example, the air conditioner may send a self-cleaning prompt signal to a smart device or a remote controller in communication connection with the air conditioner when determining that the air conditioner satisfies a self-cleaning condition, so that the smart device or the remote controller may remind a user through a pop-up window or the like.
Optionally, the communication module may first obtain an IP address of the location where the air conditioner is located, and then obtain the environmental humidity issued by the local weather bureau according to the IP address, where the environmental humidity is the environmental humidity of the location where the air conditioner is located.
And S23, executing corresponding self-cleaning operation according to the ambient humidity so as to clean the evaporator.
Alternatively, the air conditioner may determine a self-cleaning operation that should be currently performed according to the acquired ambient humidity, so as to perform a corresponding self-cleaning operation to clean the evaporator.
According to the air conditioner self-cleaning control method provided by the embodiment of the invention, the air conditioner can determine whether the air conditioner meets the self-cleaning condition or not according to the indoor environment temperature and the outdoor environment temperature, so that the environment humidity of the place where the air conditioner is located is obtained under the condition that the air conditioner meets the self-cleaning condition, and the corresponding self-cleaning operation is executed according to the environment humidity to clean the evaporator. The method can execute corresponding self-cleaning operation according to the environmental humidity under the condition that the air conditioner meets the self-cleaning condition, so that the evaporator can be cleaned in time, the evaporator is prevented from being polluted by excessive dust, the refrigerating efficiency of the air conditioner can be improved, and the refrigerating effect is ensured.
Alternatively, when the air conditioner is self-cleaned, the surface of the evaporator may be defrosted first, and then defrosted to generate condensed water, so that dust on the evaporator is adsorbed in the condensed water and is discharged to the outside through the drain pipe along with the condensed water.
On this basis, the temperature difference of the indoor environment and the outdoor environment is considered to influence the condensation capacity of the air conditioner, namely, when the difference of the indoor environment and the outdoor environment is small, the condensation capacity of the air conditioner is weak, at the moment, if the surface of the evaporator is required to be frosted, the air conditioner needs to increase work, a large amount of resources are consumed, therefore, in order to avoid the loss of a large amount of resources of the air conditioner, a temperature threshold value can be set in the air conditioner in advance, and the self-cleaning condition can include that the difference of the indoor environment and the outdoor environment reaches the temperature threshold value.
Specifically, the step S21 may be implemented by:
and under the condition that the difference value between the outdoor environment temperature and the indoor environment temperature reaches a preset temperature threshold value, determining that the air conditioner meets the self-cleaning condition.
Alternatively, the preset temperature threshold may be determined according to the local environment of the air conditioner, such as the ambient humidity, the ambient temperature, and the like. In one possible implementation, the preset temperature threshold may be 8 ℃.
It can be understood that if the difference between the outdoor ambient temperature and the indoor ambient temperature reaches the predetermined temperature threshold, it indicates that the air conditioner satisfies the self-cleaning condition.
Optionally, a time threshold may be stored in the air conditioner in advance, and the self-cleaning condition may further include that a time interval from the current time to the last time when the air conditioner performs self-cleaning reaches the time threshold. It is understood that, in this case, the air conditioner determines that the air conditioner satisfies the self-cleaning condition when the difference between the outdoor ambient temperature and the indoor ambient temperature reaches the preset temperature threshold and the time interval from the current time to the last time when the air conditioner performs self-cleaning reaches the time threshold.
Alternatively, the time threshold may be set by the user according to actual needs. In one possible implementation, the time threshold may be one month.
Optionally, since the ambient humidity may also have a certain effect on the condensation effect of the air conditioner, the corresponding self-cleaning operation may be determined for different ambient humidities. For example, a humidity threshold may be set in advance, so that the self-cleaning operation that should be performed at this time is determined according to the relationship between the humidity threshold and the acquired ambient humidity.
In a possible implementation manner, if the ambient humidity reaches the humidity threshold, it indicates that the frosting capability of the air conditioner is stronger at this time, so that the frosting on the surface of the evaporator can be directly realized through the cooling operation. Specifically, on the basis of fig. 2, fig. 3 is another schematic flow chart of the air conditioner self-cleaning control method provided in the embodiment of the present invention, please refer to fig. 3, and the step S23 may also be implemented by the following steps:
step S23-1, controlling the air conditioner to operate for a first refrigerating time according to a first refrigerating temperature under the condition that the environmental humidity reaches a humidity threshold value, so as to make the surface of the evaporator frost;
alternatively, the first cooling temperature and the first cooling time period may be temperatures and time periods set in advance by a user according to actual demands. In a possible implementation, the first refrigeration temperature may be 24 ℃ and the first refrigeration operation may be 30 minutes long. Optionally, the rotating speed of the fan may not be adjusted at this time, and the fan is controlled to keep the original rotating speed to operate.
And S23-2, after the air conditioner is controlled to operate for the first refrigerating time, controlling the air conditioner to perform defrosting operation so that condensed water is generated on the surface of the evaporator and is discharged to clean the evaporator.
It can be understood that, after the air conditioner operates at the first refrigeration temperature for the first refrigeration time period, it is considered that the surface frost condensation of the evaporator is completed, and at this time, the air conditioner can be controlled to perform the defrosting operation.
Alternatively, the air conditioner may be defrosted at a first defrosting temperature set in advance, and during defrosting, condensed water may be generated on the surface of the evaporator to adsorb dust and then discharged through the condensing pipe, so as to achieve self-cleaning of the air conditioner. In one possible implementation, the air conditioner may stop defrosting after operating for the first defrosting period.
Alternatively, the first defrosting temperature and the first defrosting time period may be set in advance and stored in the air conditioner. In a possible implementation, the first frost temperature may be 24 ℃, and the first frost duration may be 10 minutes.
In another possible implementation manner, if the ambient humidity does not reach the humidity threshold, it indicates that the condensing capacity of the air conditioner is poor at this time, so that the frost condensation on the surface of the evaporator can be achieved in an auxiliary manner by adjusting the rotation speed of the fan. Specifically, on the basis of fig. 2, fig. 4 is another schematic flow chart of the air conditioner self-cleaning control method according to the embodiment of the present invention, please refer to fig. 4, and the step S23 may be further implemented by the following steps:
step S23-3, under the condition that the environmental humidity does not reach the humidity threshold value, controlling the fan to switch to the maximum rotating speed, and controlling the air conditioner to operate for a second refrigerating time period according to a second refrigerating temperature so as to make the surface of the evaporator frost;
optionally, the number of the rotating speeds of the fans in the air conditioner may include a plurality of rotating speeds, and if the ambient humidity does not reach the humidity threshold, the air conditioner may control the rotating speed of the fan to be switched to the maximum rotating speed, so that the fan operates according to the maximum rotating speed, thereby increasing the air intake on the surface of the evaporator and improving the frost condensation capacity of the air conditioner.
