The ion sterilization process refers to a process that the positive and negative ion emitting electrodes ionize water molecules in the air under the action of high voltage to generate positive ions and negative ions, the positive and negative ions generate chemical reaction in the air to generate active substances, and the active substances decompose microorganisms in the air, such as bacteria, fungi, viruses and the like. Through the ion sterilization process, the pollutants such as fungi, planktonic bacteria, viruses and the like in the air can be removed.
If the principle is applied to the air conditioner, microorganisms such as bacteria, fungi and viruses in the air conditioner can be decomposed, so that the interior of the air conditioner is cleaner. Meanwhile, ozone with certain concentration is generated between high-voltage electrodes in the ion sterilization process due to strong corona discharge, and if the ozone is matched with the operation of an air conditioner fan, the ozone can permeate into an evaporator and the corners inside an air duct, so that bacteria are killed, odor is eliminated, and air is purified.
In the prior art, an air conditioner generally has a self-cleaning function, such as a cold expansion self-cleaning mode, namely, the air conditioner is controlled to perform refrigeration operation, and the air conditioner is controlled to perform heating and defrosting after the surface of an evaporator of the air conditioner is frosted; for another example, the high-temperature steam self-cleaning mode is to control a steam generating device inside the air conditioner to generate high-temperature steam, and clean the surface of the evaporator through the high-temperature steam. However, the two methods have poor self-cleaning effect, and are easy to leave residual pollutants such as bacteria, viruses, dust and the like. In order to achieve a better cleaning effect, the present application provides a control method for an air conditioner.
The control method for the air conditioner provided by the embodiment of the disclosure is applied to the air conditioner at least comprising the ion sterilization module. Here, the ion sterilization module has at least the above-described ion sterilization function in the air conditioner. The specific installation position of the ion sterilization module in the indoor unit may not be specifically limited.
As shown in fig. 1, an embodiment of the present disclosure provides a control method for an air conditioner, including:
and S01, under the condition that the self-cleaning of the air conditioner is finished, the air conditioner acquires the temperature of an indoor unit coil pipe of the air conditioner.
And S02, the air conditioner determines the target operation time according to the temperature of the coil pipe of the indoor unit.
Optionally, the determining, by the air conditioner, the target operation duration according to the temperature of the coil of the indoor unit includes: and the air conditioner calculates the target operation duration according to a fitting formula based on the temperature of the coil pipe of the indoor unit. Therefore, a fitting formula is obtained through a large amount of experimental data, the incidence relation between the temperature of the coil pipe of the indoor unit and the target operation time is obtained through the fitting formula, and the optimal target operation time corresponding to different temperatures of the coil pipe of the indoor unit can be reflected.
Optionally, the fitting formula comprises:
Figure BDA0003129666110000051
wherein, Y is the target running time length, A is the proportionality coefficient, and X is the temperature of the coil pipe of the indoor unit.
Here, the value of the proportionality coefficient a is determined by the type of the air conditioner, and the range of the value of a may be 2 to 10.
In some alternative embodiments, the indoor unit coil temperature is 30 degrees celsius, the scaling factor is 4, and the target run length is 22 minutes (round the calculation).
Therefore, the corresponding target operation time length is obtained by selecting different proportional coefficients according to the type of the air conditioner, so that the target operation time length is more accurate and reasonable to select.
And S03, the air conditioner controls the target operation time of the ion sterilization module, and/or controls the target operation time of the indoor fan of the air conditioner in the reverse rotation mode.
Here, the fan is reversed, and wind pressure can be generated to blow off dust deposited on the heat radiating fins or the like. If the air conditioner controls the time length of the reverse target operation of the indoor fan, the internal dust removal of the air conditioner can be realized.
Optionally, the air conditioner controls the operation target operation duration of the ion sterilization module, and/or controls the operation duration of the indoor fan in reverse rotation, including: the air conditioner determines the self-cleaning mode of the air conditioner; and the air conditioner controls the target operation time of the ion sterilization module according to the self-cleaning mode of the air conditioner, and/or controls the target operation time of the indoor fan of the air conditioner in the reverse rotation mode. Therefore, the operation of the ion sterilization module or the reversal of the indoor fan can be selectively controlled according to the cleaning focus points of different self-cleaning modes, so as to make up the cleaning weak point of the self-cleaning mode; or, the operation of the ion sterilization module is controlled, the indoor fan is controlled to rotate reversely, the sterilization effect is better, dust is removed again, and the interior of the air conditioner is cleaner.
Here, the manner of self-cleaning may be classified into two manners according to the difference of the cleaning weak point, one manner of cleaning weak point is sterilization, and the other manner of cleaning weak point is dust removal.
In some embodiments, the air conditioner is provided with a temperature threshold and a duration threshold for determining the manner in which the air conditioner is self-cleaning. Specifically, if the surface temperature of the evaporator under the current working condition of the air conditioner reaches the temperature threshold, it can be determined that the self-cleaning mode is a mode of cleaning a weak point and removing dust; if the time length of the reverse rotation of the indoor fan of the air conditioner reaches the time length threshold value, it can be determined that the self-cleaning mode is a sterilization mode for cleaning weak points.
Optionally, the air conditioner controls the ion sterilization module to operate for a target operation duration according to a self-cleaning manner of the air conditioner, and/or controls the indoor fan to rotate reversely for a target operation duration, including: under the condition that the self-cleaning mode of the air conditioner is the first self-cleaning mode, the air conditioner controls the target operation time length of the ion sterilization module, or the air conditioner controls the target operation time length of the ion sterilization module and controls the target operation time length of the indoor fan of the air conditioner in a reverse rotation mode; and under the condition that the self-cleaning mode of the air conditioner is the second self-cleaning mode, the air conditioner controls the target operation time length of the indoor fan in a reverse rotation mode, or the air conditioner controls the target operation time length of the ion sterilization module in a reverse rotation mode and controls the target operation time length of the indoor fan in a reverse rotation mode.
Here, the first self-cleaning manner refers to a self-cleaning manner in which a cleaning weak point is sterilization, and the second self-cleaning manner refers to a self-cleaning manner in which a cleaning weak point is dust removal.
Therefore, under the condition that the weak point of self-cleaning of the air conditioner is sterilization, more bacteria residues are left in the air conditioner after self-cleaning, so that the time length of the operation target of the ion sterilization module is selected to be controlled, or the time length of the operation target of the ion sterilization module is controlled and the time length of the operation target of the indoor fan of the air conditioner is controlled to be reversed, the sterilization is used as the focus to further clean the interior of the air conditioner, and the interior of the air conditioner is cleaner; under the condition that the self-cleaning weak point of the air conditioner is dust removal, more dust is left in the air conditioner after self-cleaning, so that the time length of the reverse target operation of an indoor fan of the air conditioner is controlled, or the time length of the reverse target operation of the indoor fan of the air conditioner is controlled, the dust removal is used as the focus to further clean the interior of the air conditioner, and the interior of the air conditioner is cleaner.
