In the operation process of the air conditioner, impurities such as dust, particles and the like in the air may block a filter screen of the air conditioner, so that the operation efficiency of the air conditioner is reduced, and even the air conditioner cannot normally operate.

The working principle of the air conditioner in the embodiment of the application under the refrigeration mode is as follows: the compressor compresses a gaseous refrigerant into a high-temperature high-pressure gaseous refrigerant, and then sends the gaseous refrigerant to a condenser (such as an outdoor unit shown in fig. 2) for heat dissipation to form a normal-temperature high-pressure liquid refrigerant, the heat of the refrigerant is discharged to the outside, and then the refrigerant enters a capillary tube and enters an evaporator (an indoor unit).

The method and the device for detecting the dust deposition blockage of the air conditioner, the air conditioner and the storage medium are designed based on the working principle of the air conditioner, and when the air conditioner runs, if parts such as a filter screen or an air outlet of the air conditioner and the like which are in air interaction circulation with the outside are blocked, in order to maintain the original wind speed and air conditioning effect, the working power of the external air fan is improved under the control of the controller. Therefore, the embodiment of the application monitors the power of the external fan to further determine whether the air conditioner is blocked or deposited with dust and the corresponding severity of the blockage when the air conditioner is blocked.

Fig. 2 is a flowchart of a method for detecting ash deposition blockage of an air conditioner according to an embodiment of the present application. As shown in fig. 2, the method for detecting ash deposition blockage of an air conditioner according to this embodiment includes the following steps:
s201, obtaining a first duration time of a first working state of the outer fan.
In this embodiment, the first operating state is a state where the power of the external fan is greater than or equal to a first preset power. Ways to derive external fan power include, but are not limited to: directly acquiring the power corresponding to the external fan from a power monitoring module of a controller of the air conditioner; or, the working current and the working voltage corresponding to the outer fan are obtained firstly, and then the product of the working current and the working voltage corresponding to the outer fan is calculated to obtain the power of the outer fan. It should be noted that, because the working current and the working voltage corresponding to the fan in the actual operation process of the air conditioner may be dynamically changed, the external fan power in this embodiment may also be a dynamically changing value, and obtaining the external fan power at this time means obtaining the external fan power in real time, that is, continuously monitoring the external fan power in real time.
S202, acquiring a second duration of a second working state of the outer fan.
In this embodiment, the second operating state is a state where the power of the external fan is greater than a second preset power and less than the first preset power. The first preset power and the second preset power are values that can be set as needed. The first preset power is greater than the second preset power, and the power range is divided into three intervals, namely, greater than or equal to zero, less than the second preset power, greater than or equal to the second preset power, less than the first preset power, and greater than or equal to the first preset power. Therefore, the external fan power will fall into one of the three intervals, so the first duration is used to record the duration that the external fan power falls into the interval that is greater than or equal to the first preset power, and the second duration is used to record the duration that the external fan power falls into the interval that is greater than or equal to the second preset power and less than the first preset power. The first preset power can be the power of an outer fan which is obtained through experimental tests and under the condition that parts such as an air conditioner filter screen or an air outlet and the like which are in air interaction circulation with the outside are blocked, the first preset power can be the power of the outer fan which is obtained through experimental tests and under the condition that parts such as the air conditioner filter screen or the air outlet and the like which are in air interaction circulation with the outside are deposited with dust, correspondingly, the practical meaning corresponding to the first duration is the working time of the outer fan when the air conditioner is in the blocking state, and the practical meaning corresponding to the second duration is the working time of the outer fan when the air conditioner is in the dust deposition state.
It should be noted that, when the external fan power is greater than or equal to the first preset power, the second duration is cleared; and when the power of the external air blower is smaller than the first preset power, clearing the first duration time, and when the power of the external air blower is smaller than the second preset power, clearing the first duration time and the second duration time. Specifically, the external fan power in this embodiment is a dynamically changing value, and when the external fan power changes from other intervals and falls into an interval greater than or equal to the first preset power, the accumulated time of the other intervals is cleared; and when the power of the external air blower is changed from other intervals and then falls into an interval which is more than or equal to the second preset power and less than the first preset power, clearing the accumulated time of other intervals. That is, one of the first duration and the second duration will be zero. This is because, in the operation process of the air conditioner, even when there is no dust deposition or blockage on components such as the filter screen or the air outlet of the air conditioner that perform air exchange circulation with the outside, the external fan power is a value that varies and fluctuates, and when the external fan power rises from an interval in which the second preset power is greater than or equal to the first preset power and is less than the first preset power to an interval in which the second preset power is greater than or equal to the first preset power and is greater than or equal to the first preset power, it indicates that the blockage of components such as the filter screen or the air outlet of the air conditioner that perform air exchange circulation with the outside is more serious, and therefore, the second duration needs to be cleared, and the first duration starts to be calculated. Correspondingly, when the power of the external air blower is reduced from the interval of more than or equal to the first preset power to the interval of more than or equal to the second preset power less than the first preset power, the blockage situation of parts such as an air conditioner filter screen or an air outlet and the like which are in air interactive circulation with the outside is reduced, so that the first duration time needs to be cleared, and the second duration time starts to be calculated. More, if the power of the external fan is reduced to be smaller than the second preset power, the blockage of parts such as a filter screen or an air outlet of the air conditioner and the like which are in air interaction circulation with the outside basically cannot cause hidden dangers to the normal operation of the air conditioner, so that the first duration time and the second duration time are reset, and the corresponding practical significance is met.
And S203, if the first duration is greater than or equal to a first preset time, determining that the air conditioner is in a blocked state.
And S204, if the second duration is greater than or equal to the second preset time, determining that the air conditioner is in the dust deposition state.
In this embodiment, the first preset time and the second preset time are values that can be set as needed. The first preset time is a threshold value used for judging whether the air conditioner is in a blocked state, and therefore when the first duration, namely the duration that the power of an external fan of the air conditioner is greater than or equal to the first preset power, exceeds the preset threshold value of the first preset time, the air conditioner can be determined to be in the blocked state. Correspondingly, the second preset time is a threshold value used for judging whether the air conditioner is in the dust deposition state, and when the second duration time, that is, the duration time when the external fan power of the air conditioner is greater than or equal to the second preset power and smaller than the first preset power, exceeds the preset threshold value of the second preset time, the air conditioner can be determined to be in the dust deposition state. The first preset time and the second preset time have no necessary size relationship, and when the air conditioner runs in a scene where dust is easily accumulated or blocked, the first preset time and the second preset time can be increased according to the situation.
Optionally, in step S203, if the first duration is greater than or equal to a first preset time, and the blocked area of the filter screen is greater than or equal to a first threshold and smaller than a second threshold, it is determined that the air conditioner is in a medium blocked state; if the first duration is greater than or equal to a first preset time and the blocking area of the filter screen is greater than or equal to a second threshold and smaller than a third threshold, determining that the air conditioner is in a serious blocking state; if the first duration is longer than or equal to the first preset time and the blocking area of the filter screen is larger than the third threshold value, determining that the air conditioner is in a state that foreign matters block the air inlet; the first threshold is smaller than the second threshold, and the second threshold is smaller than the third threshold.
In this embodiment, when the first duration is greater than or equal to the first preset time, that is, after it is determined that the air conditioner is in the blocked state, the present embodiment can further classify the severity of the blocked state of the air conditioner: and determining the blockage severity degree of the air conditioner according to the size relation between the blockage area of the filter screen and the first threshold value, the second threshold value and the third threshold value. Firstly, the first threshold value, the second threshold value and the third threshold value divide the blocking area of the filter screen into four intervals, namely: the threshold value is greater than or equal to zero and less than a first threshold value, greater than or equal to the first threshold value and less than a second threshold value, greater than or equal to the second threshold value and less than a third threshold value, and greater than or equal to the third threshold value. The first threshold is smaller than the second threshold, and the second threshold is smaller than the third threshold. Therefore, if the first duration is greater than or equal to a first preset time and the blocking area of the filter screen is greater than or equal to a first threshold and smaller than a second threshold, the air conditioner is determined to be in a moderate blocking state; if the first duration is greater than or equal to a first preset time and the blocking area of the filter screen is greater than or equal to a second threshold and smaller than a third threshold, determining that the air conditioner is in a serious blocking state; and if the first duration is longer than or equal to the first preset time and the blocking area of the filter screen is larger than the third threshold value, determining that the air conditioner is in a state that foreign matters block the air inlet. The blocking area of the filter screen is divided into four intervals, the blocking severity of the air conditioner is determined according to the fact that the blocking area falls into different intervals, and the moderate blocking state, the severe blocking state and the state that the air inlet is blocked by foreign matters of the air conditioner are determined according to the three intervals, namely the blocking area of the filter screen is larger, the blocking state of the air conditioner is more serious, and the corresponding relation is more in line with the actual running condition of the air conditioner.
It should be noted that the method for determining the clogged area of the filter screen in step S203 includes, but is not limited to: through setting up light emission panel in filter screen one side, set up the light reception panel at the filter screen opposite side, obtain the distribution condition that the filter screen blockked up through the luminousness of measuring the filter screen to calculate and obtain filter screen jam area. In addition, in addition to the method for determining the clogging area of the filter screen described in the present specification, there are other methods for determining the clogging area of the filter screen, which are not described in the present specification.
Optionally, in step S203, after determining that the air conditioner is in a severe blockage state, the embodiment further provides a corresponding operation method: when the air conditioner is in a severe blockage state, if the first duration is greater than or equal to a fifth preset time, prompting that the air conditioner is in the severe blockage state through at least one of an indicator light, a sound or a display icon; the power of the air conditioner is turned off. The fifth preset time is a value that can be set as needed. That is, after it is determined that the air conditioner is in the severe blocking state, if the time for which the air conditioner is in the severe blocking state is greater than the set fifth preset time, the corresponding operation is to immediately turn off the power supply of the air conditioner. This is because when the air conditioner is in a severe blockage state, the power of the external fan is at a high level, corresponding to high current and voltage of the external fan. Also, if such higher current and higher voltage conditions are maintained for too long, it is highly likely that the external fan will be damaged by the excessive current and may even affect the safety of other air conditioner components connected to the external fan. Therefore, when the time that the air conditioner is in the serious blockage state is longer than the set fifth preset time, the power supply needs to be disconnected for the first duration, the damage to hardware facilities of the air conditioner is reduced, and the safety is improved.
After the above-described embodiment step S203 has determined the clogging state of the air conditioner and the corresponding operation method is performed, the present control method can also notify the user of the clogging state and the clogging degree of the air conditioner in different ways. Specifically, when the air conditioner is in a moderate jam state, at least one of the following steps is executed: the air conditioner is prompted to be in a moderate blocking state through an indicator light; or the air conditioner is prompted to be in a moderate blocking state through sound; or, the air conditioner is prompted to be in a medium blockage state through a display icon. And when the air conditioner is in a serious blockage state, executing at least one of the following steps: prompting that the air conditioner is in a severe blockage state through an indicator light; or prompting that the air conditioner is in a serious blockage state through sound; or, the air conditioner is prompted to be in a serious blockage state through a display icon. When the air conditioner is in a state that foreign matters block the air inlet, at least one of the following steps is executed: the state that foreign matters block the air inlet is prompted by an indicator light; or, the state that foreign matters block the air inlet of the air conditioner is prompted through sound; or, the air conditioner is prompted to be in a state that foreign matters block the air inlet through the display icon. The present embodiment includes, but is not limited to, three different ways of informing the user of the air conditioner of a blockage situation, namely, sound, displaying an icon, and an indicator light. Wherein, aiming at different blockage degrees, different reminding modes can be adopted. For example, the moderate blockage state corresponds to a mode of displaying an icon, the severe blockage state corresponds to a mode of an indicator light, and the state that foreign matters block the air inlet corresponds to a mode of voice prompt to inform a user. The different reminding modes have different strengths, the mode of displaying the icon does not disturb the user when prompting the user, and the user experience and satisfaction are improved. And the mode of sound suggestion can arouse personnel's around attention for the duration, reminds personnel around in time to overhaul the situation of air conditioner, reduces the fault rate of air conditioner.
Similarly, when the air conditioner is in the dust deposition state, the present embodiment can also prompt that the air conditioner is in the dust deposition state through at least one of the indicator light, the sound or the display icon.
According to the detection method for the dust accumulation blockage of the air conditioner, provided by the embodiment of the application, the blockage or dust accumulation state of the air conditioner can be accurately detected according to the power of the external fan, invalid filter screen cleaning reminding is avoided, different operations are correspondingly executed according to the blockage severity, the operations comprise timely prompting a user and a series of operations of dust removal through fan reversal and the like, and the failure rate of the air conditioner is reduced.
Optionally, the embodiment of the application can also perform the dust removal operation according to the condenser temperature of the air conditioner.
Fig. 3 is another flowchart of a method for detecting ash deposition blockage of an air conditioner according to an embodiment of the present disclosure. As shown in fig. 3, the method for detecting ash deposition blockage of an air conditioner according to the embodiment of the present application further includes:
s301, acquiring a first temperature of the condenser when the power of the external fan is larger than or equal to a first preset power.
S302, acquiring a second temperature of the condenser when the first duration is greater than or equal to a third preset time.
And the third preset time is greater than the first preset time.
It should be noted that, the relationship between the blockage of the air conditioner filter screen or the air outlet and other components which perform air interaction circulation with the outside and the temperature of the condenser of the air conditioner is specifically as follows: the air speed can be reduced due to the blockage of parts such as an air conditioner filter screen or an air outlet and the like which are communicated with the outside, and when the air conditioner runs, the temperature of the condenser can be automatically changed by the air conditioner in order to prevent the refrigerating or heating effect from being reduced. Therefore, the temperature change condition of the condenser can visually reflect the blocking condition of components such as an air conditioner filter screen or an air outlet which are in air interactive circulation with the outside, and the blocking condition of the components such as the air conditioner filter screen or the air outlet which are in air interactive circulation with the outside is more serious the higher the temperature change of the condenser is.
In this embodiment, the first temperature and the second temperature of the condenser are obtained by the following methods: directly acquiring a first temperature and a second temperature of the condenser through a temperature sensing device; and monitoring the temperature of the condenser in real time, sending the temperature to the controller for storage, and calling the temperature from the controller when the first temperature and the second temperature of the condenser are required. The first temperature is actually the condenser temperature corresponding to the time when a part such as an air conditioner filter screen or an air outlet, which performs air interactive circulation with the outside, starts to enter a blocked state, and the second temperature is actually the condenser temperature corresponding to the time when the duration of the blockage of the part such as the air conditioner filter screen or the air outlet, which performs air interactive circulation with the outside, exceeds a third preset time.
And S303, calculating the difference value between the second temperature and the first temperature.
The difference between the second temperature and the first temperature can visually reflect the temperature change condition of the condenser before and after the air conditioner is blocked, and the larger the difference between the second temperature and the first temperature is, the more serious the air conditioner is blocked is indicated.
S304, judging whether the difference value between the second temperature and the first temperature is larger than a preset difference value threshold value.
The preset difference threshold is a threshold set for a difference between the second temperature and the first temperature, and when the difference between the second temperature and the first temperature exceeds the preset difference threshold, it indicates that the blockage condition of the air conditioner is serious, and corresponding treatment measures need to be performed, and the measures are described in detail in subsequent steps.
S305, if the difference value between the second temperature and the first temperature is larger than a preset difference value threshold value, the compressor is closed, and the outer fan is controlled to rotate reversely at the first rotating speed within fourth preset time.
In this embodiment, it is indicated that the current blockage condition of the air conditioner is serious when the difference between the second temperature and the first temperature is greater than the preset difference threshold, and the first duration time exceeds the third preset time in the foregoing step, which indicates that the blockage condition of the air conditioner is not maintained and cleaned by the user or the related personnel, so that the compressor of the air conditioner is turned off, and the external fan is turned back at the first rotation speed within the fourth preset time. In this embodiment, the first rotation speed may be a maximum rotation speed of the external fan or a larger value relative to a normal rotation speed, and the specific value of the first preset wind speed is not specifically limited in this embodiment, and may be flexibly selected according to an actual air conditioner model and a user's need. Illustratively, the normal speed is 600r/min and the first predetermined wind speed is 1000 r/min. When the first rotating speed is the maximum rotating speed of the outer fan, the air conditioner controls the outer fan to rotate reversely at the maximum rotating speed within the fourth preset time, and therefore substances such as dust and particles blocked in a filter screen or other parts of the outer fan can be effectively cleaned.
The embodiment executes the reversal dust removal operation according to the temperature of the condenser of the air conditioner, can timely remove the dust, particles and other substances attached to the air conditioner, and reduces the failure rate of the air conditioner.
Optionally, this embodiment further provides a dust removal operation method when the user actively turns off the air conditioner, which specifically includes: responding to a shutdown signal, and if the first duration is greater than zero, controlling the outer fan to rotate reversely at the first rotating speed within a fourth preset time; and if the second duration is longer than zero, controlling the outer fan to rotate reversely at a second rotating speed within sixth preset time, wherein the first rotating speed is longer than the second rotating speed.
It should be noted that, in the embodiment of the present application, a manner or a source of the shutdown signal is not specifically limited. The shutdown signal may be an infrared signal received by the air conditioner controller from a remote controller of the air conditioner or an electric signal from a button of the air conditioner entity. After receiving various shutdown signals, the embodiment first determines whether the first duration and the second duration are greater than zero, and if the first duration is greater than zero, it indicates that the air conditioner is in a blocked state when receiving the shutdown signal, and at this time, the embodiment controls the external fan to rotate reversely at the first rotation speed within a fourth preset time; if the second duration is greater than zero, it indicates that the air conditioner is in the ash deposition state when the shutdown signal is received, and at this time, the embodiment controls the outer fan to rotate reversely at the second rotation speed within the sixth preset time. As mentioned in the foregoing, the first rotational speed may be the maximum rotational speed of the outer fan. The calculation formula of the second rotating speed is as follows: BaseSpd + BaseSpd (P-P2)/P2, wherein BaseSpd in the formula is a preset basic rotating speed and is used for calculating a second rotating speed, P is the power of an external fan of the air conditioner when the air conditioner receives a shutdown signal, and P2 is a second preset power; the calculation formula of the sixth preset time is as follows: BaseTim + BaseTim (P-P2)/P2, wherein BaseTim in the formula is a preset basic time and is used for calculating a sixth preset time.
It should be added that, although the external blower power and the condenser temperature change condition in the above embodiment can intuitively reflect the blockage condition of the air conditioner, the operating condition of the air conditioner fluctuates, which may affect the accuracy of the judgment of the blockage condition of the air conditioner.
Therefore, an embodiment of the present application further provides a method for verifying a blockage condition of an air conditioner according to an air speed at an air outlet, including: acquiring the wind speed of an air outlet; and if the wind speed of the air outlet is greater than or equal to the preset wind speed, determining that the air conditioner is not in a dust deposition state and the air conditioner is not in a blocking state, and controlling the air conditioner to normally operate.
In this embodiment, the air speed at the air outlet of the air conditioner can most intuitively reflect the operation condition of the air conditioner, so that the blockage condition of the air conditioner is verified according to the air speed at the air outlet before other dust removal operations are performed. Specifically, when the wind speed at the air outlet is less than the preset wind speed, which indicates that the air conditioner is actually blocked, the operations and steps corresponding to the above embodiment are performed, and if the wind speed at the air outlet is greater than or equal to the preset wind speed, which indicates that the air conditioner is not blocked, the above embodiment determines that the result of the blocked state of the air conditioner is actually caused by non-air conditioner blocking factors such as fluctuation during the operation of the air conditioner, and thus the air conditioner should be controlled to operate normally. The preset air speed is the air speed of the air outlet when the air conditioner is in a state without any blockage or dust deposition, and represents the air speed of the air outlet when the air conditioner is in normal operation. Therefore, the embodiment compares the collected wind speed of the air outlet with the wind speed of the air outlet when the air conditioner normally operates, can check whether the air conditioner is blocked, and judges whether the external fan power, the condenser temperature change and the like of the air conditioner are caused by the fluctuation of the operation state when the air conditioner normally operates.
It should be noted that, in this embodiment, the method for acquiring the wind speed of the air outlet may be, but is not limited to: firstly, acquiring the rotating speed of an inner fan; and calculating the wind speed of the air outlet according to the rotating speed of the inner fan.
By taking the air conditioner as a cooling mode, the external air blower power is P, the first preset power is P1, the second preset power is P2, the first duration is Tm, the second duration is Tn, the first preset air speed is the maximum air speed, the first preset time is 1 minute, the second preset time is 3 minutes, the fourth preset time is m minutes, and the fifth preset time is 3+ m minutes, the manner of reminding the user is that the indicator light and the buzzer, the first temperature of the condenser is T0, the second temperature of the condenser is T1, and the preset difference threshold of the condenser temperature is Tc, as an example, fig. 4 shows a flowchart of a specific application example of the air conditioner control by applying the control method of the air conditioner of the embodiment of the present application. As shown in fig. 4, the implementation flow of this application example includes:
(1) and judging whether P is greater than or equal to P1, clearing Tm when P is less than P1, and detecting whether a shutdown signal is received when P is greater than or equal to P1.
(2) If a shutdown signal is received, the compressor is directly closed, and the outer fan is controlled to rotate reversely at the maximum wind speed; if no shutdown signal is received, Tm begins timing and saves the current condenser temperature T0.
(3) And judging whether Tm is greater than 1 minute, and if Tm is greater than 1 minute, prompting the user in a mode of flashing an indicator lamp.
(4) Judging whether Tm is greater than 3 minutes, if Tm is greater than 3 minutes, detecting whether a shutdown signal is received, if the shutdown signal is received, directly closing the compressor, and controlling the outer fan to rotate reversely at the maximum wind speed, if the shutdown signal is not received, judging whether T1-T0 is greater than Tc, if T1-T0 is greater than Tc, closing the compressor, and controlling the outer fan to rotate reversely at the maximum wind speed.
(5) And when the Tm is more than 3+ m minutes, the air conditioner is turned off, and the user is reminded in a mode of an indicator lamp and a buzzer.
Further, as shown in fig. 4, when P is less than P1 in step (1), the subsequent steps further include:
(6) and judging whether P is greater than or equal to P2, clearing Tn when P is less than P2, and detecting whether a shutdown signal is received when P is greater than or equal to P2.
(7) If a shutdown signal is received, the compressor is directly closed, and the outer fan is controlled to rotate reversely at a preset wind speed; if no shutdown signal is received, Tn starts to time.
When Tn is larger than 1 hour, the user is prompted to clear the dust on the filter screen by means of an indicator lamp.
