Referring to fig. 1, an embodiment of the present disclosure provides a control method for self-cleaning of an air conditioner, which is applied to an air conditioner having a self-cleaning function. The control method for the self-cleaning of the air conditioner comprises the following steps:
step S10, under the condition that the air conditioner operates for a set period of time, controlling the air conditioner to operate according to the self-cleaning detection parameters.
Here, the set duration is used to describe the running time from the start of the air conditioner to the stable running condition. The self-cleaning detection is carried out after the air conditioner is operated for a set period of time, so that the occurrence of false detection caused by unstable operation of the refrigerant can be reduced. Alternatively, the set duration is 1 hour.
The self-cleaning detection parameter is an air conditioner operation parameter different from the operation parameter under the stable working condition, so that the temperature of the heat exchanger is changed, and the self-cleaning judgment is convenient to compare.
Step S11, obtaining a temperature adjustment value corresponding to the self-cleaning detection parameter and a heat exchanger temperature change value of the air conditioner.
The temperature regulation value refers to a standard value of temperature change of the air conditioner heat exchanger after the self-cleaning detection parameter is operated.
The temperature change value refers to the difference between the temperature value of the air-conditioner heat exchanger before the self-cleaning detection parameter is operated and the temperature value of the air-conditioner heat exchanger after the self-cleaning detection parameter is operated.
Step S12, controlling the air conditioner to execute a cleaning mode when the detected difference value between the temperature change value and the temperature adjustment value is larger than the self-cleaning set threshold value.
In this way, the control system performs the cleaning mode when the difference between the actually detected temperature variation value and the temperature adjustment value determined according to the self-cleaning detection parameter is large.
According to the control method for self-cleaning of the air conditioner, when the air conditioner is operated to a stable state, the air conditioner is controlled to operate according to the self-cleaning detection parameters, and the temperature change value of the air conditioner heat exchanger after operation is obtained; and comparing the temperature change value with a temperature adjustment value corresponding to the self-cleaning detection parameter to determine whether the refrigerating and heating effects of the air conditioner heat exchanger are affected or not so as to determine whether to execute the cleaning program. The method can intelligently execute the cleaning mode according to the state of the heat exchanger, avoids users from not using the self-cleaning function for a long time, and achieves better user experience. The service life of the product is prolonged, and the good rate of the user to the product is improved.
Optionally, controlling the air conditioner to operate according to the self-cleaning detection parameters includes: acquiring the rotating speed of an inner fan of the air conditioner; and determining the self-cleaning detection rotating speed of the air conditioner inner fan according to the rotating speed of the fan, and controlling the inner fan to operate according to the self-cleaning detection rotating speed.
Therefore, the temperature of the heat exchanger is changed by controlling the running self-cleaning detection rotating speed of the fan.
Optionally, a first association relationship between the inner fan rotation speed interval and the self-cleaning detection rotation speed is preset in the air conditioner. Then, the self-cleaning detection rotational speed is obtained by: determining a rotating speed interval corresponding to the rotating speed of the inner fan; and determining the corresponding self-cleaning detection rotating speed according to a first association relation between the rotating speed interval corresponding to the rotating speed of the fan and the self-cleaning detection rotating speed.
Optionally, the acquisition of the self-cleaning detection rotational speed is also related to the indoor ambient temperature. Specifically, a second association relationship among the indoor environment temperature, the inner fan rotating speed interval and the self-cleaning detection rotating speed is preset in the air conditioner. Then, the self-cleaning detection rotational speed is obtained by: acquiring indoor environment temperature and determining a corresponding ring temperature interval; determining a rotating speed interval corresponding to the rotating speed of the inner fan; and determining the corresponding self-cleaning rotating speed according to a second association relation among the rotating speed interval, the ring temperature interval and the self-cleaning detection rotating speed.
Here, the second association relationship may be obtained by fitting, according to experimental data of typical working conditions in the development stage, the self-cleaning detection rotation speed determined according to the indoor environment temperature and the self-cleaning detection rotation speed determined according to the fan rotation speed. Here, the fan rotation speed may be a specific rotation speed or a gear in which the rotation speed is located.
Optionally, obtaining a temperature adjustment value corresponding to the self-cleaning detection parameter includes: acquiring a rotating speed difference value between the self-cleaning detection rotating speed and the rotating speed of the fan; and determining a corresponding first temperature regulation value according to the rotating speed interval in which the rotating speed difference value is located. In this way, a standard value (temperature adjustment value) of temperature change generated after the fan rotation speed adjustment is obtained for comparison with the detection value to determine whether the air conditioner needs to execute the cleaning mode.
Optionally, in the case that the rotation speed difference value is in a first rotation speed interval, the first temperature adjustment value is T11; the first temperature regulation value is T12 when the rotation speed difference value is in the second rotation speed interval; wherein the upper limit value of the first rotation speed interval is lower than the lower limit value of the second rotation speed interval; t11 < T12.
For example, the fan speed before the air conditioner performs the self-cleaning detection parameter is a low wind speed; the rotating speed after the self-cleaning detection parameter is executed is a high wind speed; the first temperature adjustment value is determined to be 2 c according to the gear difference (low-medium-high) between the low wind speed and the high wind speed.
Optionally, controlling the air conditioner to operate according to the self-cleaning detection parameter further includes: acquiring a set temperature of an air conditioner; and determining the self-cleaning detection set temperature of the air conditioner according to the set temperature, and controlling the air conditioner heat exchanger to operate according to the self-cleaning detection set temperature.
In this way, the self-cleaning detection of the set temperature is performed by controlling the heat exchanger so that the temperature thereof changes.
Optionally, a third association relationship between the set temperature of the air conditioner and the self-cleaning detection set temperature is preset in the air conditioner. Then, the self-cleaning detection set temperature is obtained by: determining a temperature interval corresponding to the current set temperature; and determining the corresponding self-cleaning detection set temperature according to a third association relation between the temperature interval corresponding to the set temperature and the self-cleaning detection set temperature.
Optionally, the acquisition of the self-cleaning detection set temperature is also related to the indoor ambient temperature. Specifically, a fourth association relationship among the indoor environment temperature, the air-conditioning set temperature and the self-cleaning detection set temperature is preset in the air conditioner. Then, the self-cleaning detection set temperature is obtained by: acquiring indoor environment temperature and determining a corresponding ring temperature interval; determining a temperature interval corresponding to the current set temperature; and determining the corresponding self-cleaning detection set temperature according to a fourth association relation among the ring temperature interval, the temperature interval corresponding to the set temperature and the self-cleaning detection set temperature.
Optionally, obtaining a temperature adjustment value corresponding to the self-cleaning detection parameter includes: acquiring a temperature difference value between a self-cleaning detection set temperature and a set temperature of the air conditioner; and determining a corresponding second temperature regulation value according to the rotating speed interval in which the temperature difference value is located.
In this way, a standard value (temperature adjustment value) of temperature change generated after temperature adjustment of the heat exchanger is obtained for comparison with the detection value to determine whether the air conditioner needs to execute the cleaning mode.
Optionally, in the case that the temperature difference is in the first temperature interval, the second temperature adjustment value is T21; in the case that the temperature difference is in the second temperature interval, the second temperature adjustment value is T22; wherein the upper limit value of the first temperature interval is lower than the lower limit value of the second temperature interval; t21 < T22.
For example, the set temperature before the air conditioner performs the self-cleaning detection parameter is 23 ℃; the self-cleaning detection performed sets the temperature to 20 ℃; the second temperature adjustment value is determined to be 3 c based on the difference between the two temperature values.
Optionally, the self-cleaning set threshold value is determined according to the operation mode of the air conditioner.
In different modes of operation, the rate of change of temperature of the heat exchanger is different. In this embodiment, when the air conditioner is in the cooling mode, the self-cleaning set threshold value is set to be 2 ℃; when the air conditioner operates in a heating mode, the self-cleaning set threshold value is set to be 4 ℃.
Optionally, the self-cleaning set threshold value is corrected according to the difference value between the indoor environment temperature and the set temperature. The difference value between the indoor environment temperature and the set temperature has a certain influence on the temperature change speed of the heat exchanger, so that the detection accuracy can be improved by correcting the self-cleaning set threshold value according to the difference value.
For example, when the difference between the indoor environment temperature and the set temperature is smaller than the first threshold value, the self-cleaning set threshold value is reduced according to the first adjustment amount; and when the difference value between the indoor environment temperature and the set temperature is larger than or equal to the first threshold value and smaller than the second threshold value, reducing the self-cleaning set threshold value according to the second adjustment amount. Wherein, the numerical adjustment amount corresponding to the first adjustment amount is larger than the second adjustment amount.
Optionally, the first adjustment amount is 35% of the self-cleaning set threshold T0; the second adjustment amount is 15% of the self-cleaning set threshold value.
According to the control method for self-cleaning of the air conditioner, when the air conditioner is operated to a stable state, the air conditioner is controlled to operate according to the self-cleaning detection parameters, and the temperature change value of the air conditioner heat exchanger after operation is obtained; and comparing the temperature change value with a temperature adjustment value corresponding to the self-cleaning detection parameter to determine whether the refrigerating and heating effects of the air conditioner heat exchanger are affected or not so as to determine whether to execute the cleaning program. The method can intelligently execute the cleaning mode according to the state of the heat exchanger, avoids users from not using the self-cleaning function for a long time, and achieves better user experience. The service life of the product is prolonged, and the good rate of the user to the product is improved.
As shown in fig. 2, an embodiment of the present disclosure further provides a control method for self-cleaning of an air conditioner, including:
step S20, under the condition that the air conditioner operates for a set period of time, controlling the air conditioner to operate according to the self-cleaning detection parameters.
Step S21, obtaining a temperature adjustment value corresponding to the self-cleaning detection parameter and a heat exchanger temperature change value of the air conditioner.
Step S22, controlling the air conditioner to execute a cleaning mode in the case that the detected difference value between the temperature change value and the temperature adjustment value is larger than the self-cleaning set threshold value.
Step S23, after the air conditioner executes the cleaning mode, the air conditioner is controlled to operate according to the self-cleaning detection parameters, and the temperature change value of the heat exchanger of the air conditioner is stored to update the temperature adjustment value.
Here, the self-cleaning detection parameter refers to a corresponding parameter for determining that the air conditioner is operated when the air conditioner performs the cleaning mode.
Thus, after the air conditioner executes the cleaning mode, the temperature data of the heat exchanger under the same working condition in the state is acquired by running the self-cleaning detection parameter again so as to update the temperature regulation value serving as the standard value of self-cleaning judgment and serve as the basis of the re-judgment. The method can intelligently execute the cleaning mode according to the state of the heat exchanger, avoids users from not using the self-cleaning function for a long time, and achieves better user experience. The service life of the product is prolonged, and the good rate of the user to the product is improved.

Wherein the detection module 31 is configured to control the air conditioner to operate according to the self-cleaning detection parameter under the condition that the air conditioner operates for a set period of time; the acquisition module 32 is configured to acquire a temperature adjustment value corresponding to the self-cleaning detection parameter, and a heat exchanger temperature variation value of the air conditioner; the control module 33 is configured to control the air conditioner to perform the cleaning mode in the case where the detected difference between the temperature variation value and the temperature adjustment value is greater than the self-cleaning set threshold value.
By adopting the control device for self-cleaning of the air conditioner, which is provided by the embodiment of the disclosure, the air conditioner is controlled to operate according to the self-cleaning detection parameters when the air conditioner operates to a stable state, and the temperature change value of the air conditioner heat exchanger after operation is obtained; and comparing the temperature change value with a temperature adjustment value corresponding to the self-cleaning detection parameter to determine whether the refrigerating and heating effects of the air conditioner heat exchanger are affected or not so as to determine whether to execute the cleaning program. The method can intelligently execute the cleaning mode according to the state of the heat exchanger, avoids users from not using the self-cleaning function for a long time, and achieves better user experience.
