[0002] Air conditioners have become a necessity, and their use has become universal. With the increasing popularity of air conditioners, users are becoming increasingly reliant on their selection and use, and the impact of air conditioner operation on indoor air quality has become a key factor in determining their choice. During use, because air conditioners operate in a closed environment with poor air circulation, dust and mildew easily accumulate on the surfaces of components in the airflow path, such as filters and heat exchangers. This accumulation over time not only affects air quality but can also lead to potential quality issues with the air conditioner. Prior art methods for detecting filter blockage include obtaining a current wind resistance value and determining whether the filter is clogged based on a comparison of the current wind resistance value with a preset wind resistance value.

[0003] In the process of implementing the embodiments of the present disclosure, it was found that there are at least the following problems in the related art: it is difficult to determine whether there is dust accumulation, dirt, etc. on the air guide plate, resulting in the air guide plate being unable to be cleaned in time.

[0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field. Summary of the Invention

[0005] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below.

[0006] The embodiments of the present disclosure provide a detection method and device for an air conditioner, an air conditioner, and a storage medium, which can determine whether there is dust accumulation, dirt, etc. on the surface of an air guide plate.

[0007] In some embodiments, a detection method for an air conditioner includes:

[0010] Determine the ratio V1 / V of the current air outlet speed V1 to the preset air outlet speed V, and the ratio N' / N of the current torque N' to the preset torque N;

[0011] The change in the weight of the air deflector is determined based on the comparison results of V1 / V and N' / N.

[0012] In some embodiments, a detection device for an air conditioner includes a processor and a memory storing program instructions, wherein the processor is configured to execute the detection method for the air conditioner provided in the aforementioned embodiment when running the program instructions.

[0013] In some embodiments, the air conditioner comprises:

[0014] ontology;

[0015] The detection device for the air conditioner provided in the aforementioned embodiment is installed on the main body.

[0016] In some embodiments, the storage medium stores program instructions, and when the program instructions are run, they execute the detection method for the air conditioner provided in the above embodiments.

[0017] The detection method and device for air conditioners, air conditioners, and storage media provided by the embodiments of the present disclosure can achieve the following technical effects: after the air conditioner is started, the current air outlet speed V1 of the air conditioner and the current torque N' of the motor when the air guide plate swings to a preset angle are obtained, and the change in the weight of the air guide plate is determined based on the comparison results of the ratio V1 / V of the current air outlet speed V1 and the preset air outlet speed V, and the ratio N' / N of the current torque N' and the preset torque N.

[0031] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0033] The air conditioner includes a main body, which includes: a shell, an air guide plate and a motor. The shell is provided with an air inlet and an air outlet. The air guide plate is arranged at the air outlet. The motor is connected to the air guide plate to drive the air guide plate to swing, thereby changing the air supply direction.

[0034] In some embodiments, the air conditioner further includes a detection device connected to the main body, the detection device being configured to detect changes in the weight of the air deflector. Based on the changes in the weight of the air deflector, it can be determined whether there is dirt on the surface of the air deflector. When the weight of the air deflector increases, it indicates that there is dirt on the surface of the air deflector, i.e., the presence of dirt causes the weight of the air deflector to increase.

[0035] Combine Figure 1 As shown, the embodiment of the present disclosure provides a detection method for an air conditioner, comprising:

[0036] S01, after the air conditioner is started, the control device controls the air guide plate to start swinging.

[0037] S02 , the control device obtains the current air outlet speed V1 of the air conditioner and the current torque N′ of the motor when the air guide plate swings to a preset angle.

[0038] S03 , the control device determines a ratio V1 / V between the current air outlet speed V1 and the preset air outlet speed V, and a ratio N′ / N between the current torque N′ and the preset torque N.

[0039] S04, the control device determines the change in the weight of the air deflector according to the comparison results of V1 / V and N' / N.

[0040] In step S01, after the air conditioner is started, the control device can control the air guide plate to swing to change the air supply direction.

[0041] In step S02, after the air conditioner is started, it has a certain air flow rate. At the current air flow rate, the air deflector has a corresponding motor torque value at each angle. The motor is a stepper motor. Using a stepper motor can drive the air deflector to swing.

[0042] Optionally, the air outlet speed of the air conditioner is detected by a wind speed sensor. There are multiple ways to obtain the air outlet speed of the air conditioner. In one method, the control device obtains the air outlet speed of the air conditioner using its own wind speed sensor. In another method, the control device receives the air outlet speed detected by a wind speed sensor with which it can wirelessly communicate.

[0043] Optionally, the control device obtains the magnitude of the motor torque by detecting the current value of the stepping motor.

[0044] In step S03, since the force-bearing area of ​​the air guide plate is fixed, the torque and air outlet speed of the stepper motor should be proportional to the weight of the air guide plate. Therefore, by judging the relationship between the air outlet speed ratio and the stepper motor torque ratio, it can be used to determine whether the air guide plate is contaminated with dust, mildew, etc.

[0045] In step S04, the ratio of the current air velocity V1 to the preset air velocity V is calculated, as is the ratio N' / N of the current torque N' to the preset torque N. When the air deflector is clean, the two ratios should be identical. If the air deflector surface becomes contaminated, the weight of the air deflector increases, resulting in a significant difference between the two ratios. Therefore, based on these two ratios, the weight change of the air deflector can be determined, thereby confirming whether the air deflector surface is contaminated.

[0046] The detection method provided in the embodiment of the present disclosure controls the swinging of the air guide plate after the air conditioner is started, obtains the current air outlet speed V1 of the air conditioner and the current torque N' of the motor when the air guide plate swings to a preset angle, and determines the change in the weight of the air guide plate based on the comparison results of the ratio V1 / V of the current air outlet speed V1 and the preset air outlet speed V, and the ratio N' / N of the current torque N' and the preset torque N. Since the weight change of the air guide plate can reflect whether there is a lot of dust, mildew, dirt, etc. on its surface, the surface condition of the air guide plate can be obtained by determining the weight change of the air guide plate, so that the air guide plate can be cleaned in time.

[0047] Optionally, the preset angle is the angle when the wind deflector is in a horizontal position. When the wind deflector is in a horizontal position, the wind resistance is minimal, and the measurement result of the motor torque value is more accurate, thereby making the accuracy of the final detection result higher.

[0048] Optionally, the preset angle is an angle within 45 degrees of the wind deflector being tilted upward or downward relative to the horizontal position. In this way, the weight change of the wind deflector can also be detected according to the method provided in the embodiment of the present disclosure.

[0049] Optionally, the preset airflow speed and preset torque may be pre-set values. The preset airflow speed and the corresponding preset torque may be pre-programmed into the air conditioner. Thus, when the air conditioner is started for the first time or not, the change in the air deflector weight can be determined based on the current airflow speed V1 and current torque N' obtained, the preset airflow speed, the preset torque N, and the preset airflow speed V.

[0050] Optionally, the preset air flow speed and preset torque may be obtained when the air conditioner is first started. When the air conditioner is first started, it is assumed that the surface of the air deflector is clean and free of dirt. The air flow speed and motor torque obtained at this time may serve as standard values ​​representing the cleanliness of the air deflector surface. Upon subsequent starts of the air conditioner, the current air flow speed and motor torque may be detected, and calculations may be performed based on the detected values ​​and the preset values ​​to determine changes in the weight of the air deflector during subsequent operation of the air conditioner, thereby determining whether the surface of the air deflector is dirty.

[0051] In some embodiments, the control device determines the change in the weight of the air deflector according to the comparison result of V1 / V and N' / N, including:

[0052] When V1 / V=N' / N, the control device determines that the weight of the air deflector has not changed;

[0053] When V1 / V<N' / N, the control device determines that the weight of the air guide plate is increased.

[0054] The detection method for an air conditioner provided by the embodiments of the present disclosure can further determine whether the weight of the air deflector has increased or not changed based on the comparison results of V1 / V and N' / N. If the control device determines that the weight of the air deflector has not changed, it is considered that the surface of the air deflector is still clean and does not need to be cleaned. If the control device determines that the weight of the air deflector has increased, it is considered that the surface of the air deflector is significantly dirty and needs to be cleaned.

[0055] Optionally, after the control device determines that the weight of the air deflector has increased, the method further includes: the control device reminding the user to clean the air deflector. By reminding the user, the user can be aware that there is dirt on the surface of the air deflector, so that the user can clean it in time.

[0056] Optionally, after the control device determines that the weight of the air guide plate has increased, the control device further controls the air conditioner to increase the wind speed of the fan to blow away dust on the surface of the air guide plate. In this way, by increasing the wind speed to blow air on the surface of the air guide plate, dust and other debris on the surface are forced to fall away from the air guide plate.

[0057] Combine Figure 2 As shown, the embodiment of the present disclosure provides another detection method for an air conditioner, comprising:

[0058] S01, after the air conditioner is started, the control device controls the air guide plate to start swinging.

[0059] S02 , the control device obtains the current air outlet speed V1 of the air conditioner and the current torque N′ of the motor when the air guide plate swings to a preset angle.

[0060] S03 , the control device determines a ratio V1 / V between the current air outlet speed V1 and the preset air outlet speed V, and a ratio N′ / N between the current torque N′ and the preset torque N.

[0061] S041, the control device determines whether V1 / V is less than N' / N, and if so, executes step S052, and if not, executes step S053.

[0062] S042: The control device determines that the weight of the air deflector increases.

[0063] S043: The control device determines that the weight of the air deflector has not increased.

[0064] The detection method for air conditioners provided in the embodiment of the present disclosure can determine the change in the weight of the air guide plate based on the comparison results of the ratio V1 / V of the current air outlet speed V1 and the preset air outlet speed V, and the ratio N' / N of the current torque N' and the preset torque N.

[0065] At the same wind speed, when the deflector surface is heavily contaminated, causing it to weigh more, the motor torque driving the deflector increases compared to when the deflector surface is clean. If the deflector surface is clean, meaning its weight remains unchanged, the motor torque should increase or decrease proportionally with increasing or decreasing airflow speed. If the motor torque increases or decreases at a rate greater than the rate of increase or decrease in airflow speed, this indicates an increase in deflector weight, meaning the deflector surface is heavily contaminated.

[0066] In some embodiments, the preset air velocity V is the air velocity when the air conditioner is first turned on. When the air conditioner is first turned on, it is assumed that the surface of the air guide plate is clean. The air velocity at this time can be used as a standard value, i.e., the preset air velocity, to ensure accurate subsequent judgment results.

[0067] In some embodiments, the preset torque N is the motor torque corresponding to when the air deflector is swung to a preset angle when the air conditioner is first turned on. When the air conditioner is first turned on, the air deflector surface is assumed to be clean. The motor torque corresponding to the air deflector at the preset angle can be used as a standard value, i.e., the preset torque, to ensure accurate subsequent determinations.

[0068] Combine Figure 3 As shown, in some embodiments, the preset torque N is obtained by:

[0069] S051: When the air conditioner is turned on for the first time, the control device controls the air guide plate to swing for M cycles.

[0070] S052, each time the air guide plate swings to a preset angle, the control device obtains the corresponding motor torque n, and obtains n1, n2, ..., nm.

[0071] S053, the control device calculates the average value of the motor torques n1, n2, ..., nm as the preset torque N.

[0072] In step S051, the control device controls the air deflector to swing for M cycles to obtain multiple motor torque values. One cycle is when the air deflector swings from the maximum air outlet angle to the minimum air outlet angle. Optionally, M is 15 to 25. This allows for the acquisition of an appropriate number of motor torque values ​​without taking too long.

[0073] In step S052, each time the air guide plate swings to a preset angle, the control device obtains the motor torque, so that multiple motor torques at the preset angles can be obtained.

[0074] In step S053, the control device can obtain the motor torque corresponding to the air guide plate at the position by averaging multiple motor torques, and use the motor torque as the preset torque N to make the final detection result more accurate.

[0075] The embodiment of the present disclosure uses the average value method to determine the preset torque N at the preset angle of the air guide plate when the air conditioner is started for the first time, which can ensure the accuracy of subsequent detection results.

[0076] As an example, the preset torque N is obtained in the following way:

[0077] When the air conditioner is turned on for the first time, the control device controls the air guide plate to swing for 15 cycles.

[0078] Each time the air deflector swings to a preset angle, the control device obtains the corresponding motor torque, and obtains 116.7, 116.6, 116.6, 116.5, 116.8, 116.5, 116.6, 116.7, 116.8, 116.7, 116.6, 116.5, 116.6, 116.7, 116.6.

[0079] The control device calculates an average value of the motor torque as 116.6 as the preset torque.

[0080] Combine Figure 4 As shown, in some embodiments, the current torque N' of the motor when the air deflector is swung to a preset angle is obtained by:

[0081] S044, the control device controls the air guide plate to swing for L cycles, and obtains the corresponding motor torque §N each time it swings to a preset angle, thereby obtaining §N1, §N2, ..., §NL.

[0082] S045 , the control device calculates an average value of the motor torques §N1 , §N2 , . . . , §NL as the current motor torque N′ when the air guide plate swings to a preset angle.

[0083] The disclosed embodiment can obtain the motor torque of the wind guide plate that swings L cycles at a preset angle through the control device, and obtain multiple motor torque values. By taking the average value, a more accurate current motor torque N' can be obtained to improve the accuracy of subsequent detection results.

[0084] Optionally, L is 15 to 25. The control device can obtain a suitable amount of motor torque by controlling the air guide plate to swing for 15 to 25 cycles, and obtain a relatively accurate current motor torque N' by calculating the average value.

[0085] Combine Figure 5 As shown, in some embodiments, the present disclosure provides another detection method for an air conditioner, including:

[0086] S061: When the air conditioner is turned on for the first time, obtain an air outlet speed V as a preset air outlet speed.

[0087] S062: The control device controls the air guide plate to swing for M cycles.

[0088] S063 , each time the air deflector swings to a preset angle, the control device obtains the corresponding motor torque n, and obtains n1, n2, ..., nm.

[0089] S064, the control device calculates the average value of the motor torques n1, n2, ..., nm as the preset torque N.

[0090] S065: When the air conditioner is not started for the first time, the control device obtains the current air outlet speed V1 of the air conditioner.

[0091] S066: The control device controls the air guide plate to swing for L cycles.

[0092] S067: Each time the air deflector swings to a preset angle, the control device obtains the corresponding motor torque §N, thereby obtaining §N1, §N2, ..., §NL.

[0093] S068 , the control device controls and calculates the average value of the motor torques §N1 , §N2 , . . . , §NL as the current torque N′ of the motor when the air guide plate swings to a preset angle.

[0094] S03 , the control device determines a ratio V1 / V between the current air outlet speed V1 and the preset air outlet speed V, and a ratio N′ / N between the current torque N′ and the preset torque N.

[0095] S041, the control device determines whether V1 / V is less than N' / N, if so, executes step S042, if not, executes step S043.

[0096] S042: The control device determines that the weight of the air deflector increases.

[0097] S043: The control device determines that the weight of the air deflector has not increased.

[0098] The detection method provided in the embodiment of the present disclosure adopts the average value method to determine the preset torque N and the current torque N', and determines whether the weight of the air guide plate has increased or not based on the comparison results of the ratio of the current air outlet speed V1 and the preset air outlet speed V and the ratio of the current torque N' of the motor and the preset torque N, thereby determining whether there is dirt on the surface of the air guide plate.

[0099] As an example, when the air conditioner is turned on for the first time, it operates in a low-wind mode with a fan speed of 850 r / min. The air outlet speed V is obtained to be 1.74 m / s. The control device controls the air deflector to swing for 20 cycles. By calculating the average value of the motor torques n1, n2, ..., nm each time the air deflector swings to the horizontal position, the preset torque N is obtained to be 116.7 mN·m. When the air conditioner is not started for the first time, the current air outlet speed V1 of the air conditioner is obtained to be 1.81 m / s, and the current motor torque N' when the air deflector swings to the preset angle is 125.6 mN·m. By calculating, V1 / V = 1.81 / 1.74 = 1.04, N' / N = 125.6 / 116.7 = 1.08, and V1 / V < N' / N, it is determined that the weight of the air deflector has increased.

[0100] The present disclosure provides another detection method for an air conditioner, including:

[0101] After the air conditioner is started, the control device controls the air guide plate to start swinging air;

[0102] The control device obtains the current air outlet speed V1 of the air conditioner and the current torque N' of the motor when the air guide plate swings to a preset angle;

[0103] When the current torque N' of the motor is greater than the torque threshold N0, the control device controls the air guide plate to swing in the opposite direction away from the preset angle;

[0104] The control device obtains the current torque N' of the motor. When the current torque N' of the motor is less than or equal to the torque threshold N0, the control device determines the ratio V1 / V of the current air outlet speed V1 to the preset air outlet speed V, and the ratio N' / N of the current torque N' to the preset torque N.

[0105] The control device determines the change in the weight of the air deflector according to the comparison results of V1 / V and N' / N.

[0106] The detection method provided by the disclosed embodiment, when the current motor torque N' is greater than the torque threshold N0, determines that the excessive current motor torque N' may be due to debris trapped in the air deflector. At this point, the current motor torque is unsuitable for substitution into subsequent calculations, otherwise the control device would mistakenly determine that the air deflector has increased in weight and is contaminated. Therefore, the control device controls the air deflector to swing in the opposite direction, deviating from the preset angle to eliminate the debris trapped in the air deflector. Subsequent judgments are then made based on the motor torque corresponding to the deflector after the deviation. If the motor torque after the deviation is less than the torque threshold N0, the control device again substitutes the current motor torque into the formula to determine the change in the air deflector's weight.

[0107] Optionally, the control device controls the air deflector to swing in the opposite direction by a preset angle of 10° to 15°. In this way, the air deflector can release the trapped debris, and the motor torque obtained again can be used for subsequent calculations.
