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 with a self-cleaning function. The control method for self-cleaning of the air conditioner comprises the following steps:
and step S10, controlling the air conditioner to operate according to the self-cleaning detection parameters under the condition that the air conditioner operates for a set time.
Here, the set time period is used to express an operation time from the start of the air conditioner to the stabilization of the operation condition. The self-cleaning detection is carried out after the air conditioner runs for a set time, so that the occurrence of false detection caused by unstable running of the refrigerant can be reduced. Alternatively, the set time period is 1 hour.
The self-cleaning detection parameters refer to the air conditioner operation parameters different from the operation parameters under the stable working condition, so that the temperature of the heat exchanger is changed, and the comparison of self-cleaning judgment is facilitated.
And step S11, acquiring a temperature adjusting value corresponding to the self-cleaning detection parameter and a temperature change value of a heat exchanger of the air conditioner.
The temperature adjusting value is a standard value of the temperature change of the air conditioner heat exchanger after the self-cleaning detection parameter is operated.
The temperature change value is the difference between the temperature value of the air-conditioning heat exchanger before the self-cleaning detection parameter is operated and the temperature value of the air-conditioning heat exchanger after the self-cleaning detection parameter is operated.
And step S12, controlling the air conditioner to execute a cleaning mode under the condition that the detection difference value between the temperature change value and the temperature adjusting value is larger than the self-cleaning setting threshold value.
In this way, the control system executes the cleaning mode when the difference between the actually detected temperature variation value and the temperature adjustment value determined based on the self-cleaning detection parameter is large.
According to the control method for self-cleaning of the air conditioner, when the air conditioner runs to a stable state, the air conditioner is controlled to run according to self-cleaning detection parameters, and a temperature change value of a heat exchanger of the air conditioner after running is obtained; and determining whether the cooling and heating effects of the air-conditioning heat exchanger are influenced or not by comparing the temperature change value with a temperature adjusting value corresponding to the self-cleaning detection parameter so as to judge whether to execute a cleaning program or not. The method can intelligently execute the cleaning mode according to the state of the heat exchanger, avoids the user 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 appraisal rate of the product by a user is improved.
Optionally, controlling the air conditioner to operate according to a self-cleaning detection parameter includes: acquiring the rotating speed of an inner fan of the air conditioner; and determining the self-cleaning detection rotating speed of the fan in the air conditioner according to the rotating speed of the fan, and controlling the inner fan to operate according to the self-cleaning detection rotating speed.
So, through control fan operation automatically cleaning detection rotational speed for the heat exchanger temperature changes.
Optionally, a first correlation between the internal fan rotation speed interval and the self-cleaning detection rotation speed is preset in the air conditioner. Then, the self-cleaning detection rotation speed is obtained by: determining a rotating speed interval corresponding to the rotating speed of the fan of the inner fan; and determining the corresponding self-cleaning detection rotating speed according to the 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 obtaining of the self-cleaning detection rotation speed is also related to the indoor ambient temperature. Specifically, a second correlation relation 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 rotation speed is obtained by: acquiring indoor environment temperature and determining a corresponding environment temperature interval; determining a rotating speed interval corresponding to the rotating speed of the fan of the inner fan; and determining the corresponding self-cleaning rotating speed according to the second association relation among the rotating speed interval, the ring temperature interval and the self-cleaning detection rotating speed.
Here, the second correlation relationship may be obtained by fitting a self-cleaning detection rotation speed determined according to the indoor environment temperature and a self-cleaning detection rotation speed determined according to the blower rotation speed according to experimental data of typical conditions in the development stage. Here, the rotation speed of the fan may be a specific rotation speed, and may also be a gear where the rotation speed is located.
Optionally, obtaining a temperature adjustment value corresponding to the self-cleaning detection parameter includes: acquiring a rotation speed difference value between a self-cleaning detection rotation speed and a fan rotation speed; and determining a corresponding first temperature adjusting value according to the rotating speed interval in which the rotating speed difference value is positioned. Therefore, a standard value (temperature adjusting value) of the temperature change generated after the rotation speed of the fan is adjusted is obtained and is used for being compared with the detection value to judge whether the air conditioner needs to execute the cleaning mode or not.
Alternatively, in the case where the rotation speed difference is in the first rotation speed section, the first temperature adjustment value is T11; under the condition that the rotation speed difference value is in the second rotation speed interval, the first temperature adjusting value is T12; wherein, the upper limit value of the first rotating speed interval is lower than the lower limit value of the second rotating speed interval; t11 < T12.
For example, the rotating speed of a fan before the air conditioner executes the self-cleaning detection parameter is low wind speed; the rotating speed after the self-cleaning detection parameters are executed is high wind speed; the first temperature adjustment value is determined to be 2 deg.c based on the gear difference between the low wind speed and the high wind speed (low-medium-high).
Optionally, controlling the air conditioner to operate according to a self-cleaning detection parameter, further comprising: 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 heat exchanger of the air conditioner to operate according to the self-cleaning detection set temperature.
Thus, the heat exchanger is controlled to carry out self-cleaning to detect the set temperature, so that the temperature of the heat exchanger is changed.
Optionally, a third correlation 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 correlation between the temperature interval corresponding to the set temperature and the self-cleaning detection set temperature.
Optionally, the obtaining of the self-cleaning detection set temperature is further related to the indoor ambient temperature. Specifically, a fourth correlation between the indoor ambient 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 environment temperature interval; determining a temperature interval corresponding to the current set temperature; and determining the corresponding self-cleaning detection set temperature according to the fourth correlation 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 adjusting value according to the rotating speed interval in which the temperature difference value is positioned.
Therefore, a standard value (temperature adjusting value) for generating temperature change after the temperature of the heat exchanger is adjusted is obtained and is used for comparing with the detection value to judge whether the air conditioner needs to execute the cleaning mode.
Alternatively, in the case where the temperature difference is in the first temperature interval, the second temperature adjustment value is T21; in the case where 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 of the air conditioner before the self-cleaning detection parameters are executed is 23 ℃; the self-cleaning detection is carried out with the set temperature of 20 ℃; the second temperature adjustment value is determined to be 3 c based on the difference between the two temperature values.
Optionally, the value of the self-cleaning setting threshold is determined according to the operation mode of the air conditioner.
The speed of temperature change of the heat exchanger is different in different operation modes. In this embodiment, when the air conditioner operates in the cooling mode, the value of the self-cleaning setting threshold is 2 ℃; when the air conditioner operates in the heating mode, the value of the self-cleaning set threshold is 4 ℃.
Optionally, the value of the self-cleaning setting threshold is corrected according to a difference between the indoor environment temperature and the setting temperature. The difference value between the indoor environment temperature and the set temperature has certain influence on the temperature change speed of the heat exchanger, so the self-cleaning set threshold value is corrected according to the difference value, and the detection accuracy can be improved.
For example, when the difference between the indoor environment temperature and the set temperature is smaller than a first threshold, the self-cleaning set threshold is reduced according to a first adjustment amount; and when the difference value between the indoor environment temperature and the set temperature is greater than or equal to the first threshold and less than the second threshold, reducing the self-cleaning set threshold according to a second regulating quantity. And 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 setting threshold T0; the second adjustment amount is 15% of the self-cleaning setting threshold.
According to the control method for self-cleaning of the air conditioner, when the air conditioner runs to a stable state, the air conditioner is controlled to run according to self-cleaning detection parameters, and a temperature change value of a heat exchanger of the air conditioner after running is obtained; and determining whether the cooling and heating effects of the air-conditioning heat exchanger are influenced or not by comparing the temperature change value with a temperature adjusting value corresponding to the self-cleaning detection parameter so as to judge whether to execute a cleaning program or not. The method can intelligently execute the cleaning mode according to the state of the heat exchanger, avoids the user 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 appraisal rate of the product by a user is improved.
With reference to fig. 2, an embodiment of the present disclosure further provides a control method for self-cleaning of an air conditioner, including:
and step S20, controlling the air conditioner to operate according to the self-cleaning detection parameters under the condition that the air conditioner operates for a set time.
And step S21, acquiring a temperature adjusting value corresponding to the self-cleaning detection parameter and a heat exchanger temperature change value of the air conditioner.
And step S22, controlling the air conditioner to execute a cleaning mode under the condition that the detection difference value between the temperature change value and the temperature adjusting value is larger than the self-cleaning setting threshold value.
And step S23, after the air conditioner executes the cleaning mode, controlling the air conditioner to operate according to the self-cleaning detection parameters, and storing the temperature change value of the heat exchanger of the air conditioner so as to update the temperature regulation 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.
In this way, after the air conditioner executes the cleaning mode, the self-cleaning detection parameter is operated again, and the temperature data of the heat exchanger under the same working condition is acquired to update the temperature regulation value used as the standard value of the self-cleaning judgment as the basis of the re-judgment. The method can intelligently execute the cleaning mode according to the state of the heat exchanger, avoids the user 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 appraisal rate of the product by a user is improved.

By adopting the control device for self-cleaning of the air conditioner, 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 heat exchanger of the air conditioner after operation is obtained; and determining whether the cooling and heating effects of the air-conditioning heat exchanger are influenced or not by comparing the temperature change value with a temperature adjusting value corresponding to the self-cleaning detection parameter so as to judge whether to execute a cleaning program or not. The method can intelligently execute the cleaning mode according to the state of the heat exchanger, avoids the user not using the self-cleaning function for a long time, and achieves better user experience.
