Abstract
Description
Technical Field
[0001] The present application relates to the technical field of air conditioners, for example, to a method for controlling an air conditioner and an air conditioner. Background Art
[0002] At present, air conditioners have become an indispensable household appliance in people's daily life. Among them, the fan is an indispensable and important component of the air conditioner. The fan is used to blow cold air or hot air into the room to achieve indoor temperature control. The fan in the air conditioner is usually composed of fan blades, a motor and a fan bearing, wherein the motor and the fan bearing are respectively located at both ends of the fan blade. The rotating motor drives the fan blade to rotate to achieve blowing. The fan bearing is used to reduce the friction coefficient during the rotation of the fan blade and ensure the rotation accuracy of the fan blade so that the fan blade can rotate stably and continuously. However, during the use of the fan, the fan will fail to rotate or the rotation is blocked. After a period of time after the fan fails, the temperature of the inner coil of the air conditioner will be too high or too low. If the temperature of the inner coil is too low, it will be frozen. If the temperature of the inner coil is too high, it will trigger the inner coil protection of the air conditioner, causing the air conditioner to shut down. It can be seen that the failure of the fan will not only reduce the efficiency of indoor temperature control, but also damage various components of the air conditioner, resulting in a shorter service life of the air conditioner. In the related art, it is usually determined whether the fan fails by whether the temperature of the inner coil is within a preset range. If the temperature of the inner coil is within the preset range, it is determined that the fan has not failed. If the temperature of the inner coil is not within the preset range, it is determined that the fan has failed.
[0003] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art: In the related art, whether the fan fails is determined by whether the temperature of the inner coil is within a preset range. The cause of the fan failure cannot be determined. As a result, the fan cannot be repaired in a targeted manner, which increases the difficulty of repairing the fan.
[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 the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0026] In order to be able to understand the features and technical contents of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure.

[0028] Unless otherwise stated, the term "plurality" means two or more.
[0029] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.
[0030] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.
[0031] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.
[0032] The method for controlling an air conditioner provided by the embodiment of the present disclosure is applied to an air conditioner. The air conditioner obtains the real-time rotation speed of the indoor fan and the real-time current of the motor. The indoor fan includes a motor. It is determined whether the indoor fan is faulty based on the real-time rotation speed and the real-time current. And when it is determined that the indoor fan is faulty, the cause of the fault of the indoor fan is determined based on the real-time rotation speed and the real-time current. In this way, when it is determined that the indoor fan is faulty based on the real-time rotation speed and the real-time current, the cause of the fault of the indoor fan is determined based on the real-time rotation speed and the real-time current. This makes it easier for maintenance personnel to repair the indoor fan of the air conditioner according to the cause of the fault, thereby reducing the difficulty of repairing the fan.
[0033] Furthermore, the air conditioner is also provided with a speed sensor and a current sensor. The speed sensor is provided on the bearing of the internal fan, and the speed sensor is used to detect the real-time speed of the bearing, that is, the real-time speed of the internal fan. The current sensor is provided on the motor. The current sensor is used to detect the real-time current of the motor.
[0034] Combination Figure 1 As shown, the embodiment of the present disclosure provides a method for controlling an air conditioner, comprising:
[0035] Step S101, the air conditioner obtains the real-time rotation speed of the indoor fan and the real-time current of the motor; the indoor fan includes a motor.
[0036] Step S102: The air conditioner determines whether the indoor fan is faulty according to the real-time rotation speed and the real-time current.
[0037] Step S103, when the air conditioner determines that the indoor fan is faulty, the air conditioner determines the cause of the fault of the indoor fan according to the real-time rotation speed and the real-time current.
[0038] The method for controlling an air conditioner provided by the embodiment of the present disclosure is adopted. The real-time rotation speed of the indoor fan and the real-time current of the motor are obtained, and then whether the indoor fan is faulty is determined according to the real-time rotation speed and the real-time current. And in the case where the indoor fan is determined to be faulty, the cause of the fault of the indoor fan is determined according to the real-time rotation speed and the real-time current. In this way, in the case where the indoor fan is determined to be faulty according to the real-time rotation speed and the real-time current, the cause of the fault of the indoor fan is determined according to the real-time rotation speed and the real-time current. This makes it easier for maintenance personnel to repair the indoor fan of the air conditioner according to the cause of the fault, thereby reducing the difficulty of repairing the fan. At the same time, since the real-time rotation speed of the indoor fan and the real-time current of the motor will change immediately when the indoor fan fails. Therefore, the indoor fan fault can be detected more timely through the real-time rotation speed of the indoor fan and the real-time current of the motor. The accuracy is higher.
[0039] Furthermore, the air conditioner obtains the real-time rotation speed of the indoor fan and the real-time current of the motor, including: the air conditioner obtains the real-time rotation speed of the indoor fan using a rotation speed sensor and the air conditioner obtains the real-time current of the motor using a current sensor.
[0040] Optionally, the air conditioner determines whether the indoor fan is faulty according to the real-time rotation speed and the real-time current, including: the air conditioner obtains a target rotation speed of the indoor fan. The air conditioner obtains a target current corresponding to the target rotation speed. The air conditioner determines that the indoor fan is faulty when the real-time rotation speed is less than the target rotation speed and the real-time current is greater than the target current. In this way, it is possible to accurately determine that the indoor fan is faulty when the real-time rotation speed of the indoor fan is less than the target rotation speed and the real-time current is greater than the target current.
[0041] The target speed of the internal fan is the speed set by the user.
[0042] Furthermore, the air conditioner obtains the target current corresponding to the target speed, including: the air conditioner uses a preset target current database to look up the target speed to obtain the target current corresponding to the target speed. The preset target current database stores the corresponding relationship between the target speed and the target current.
[0043] The preset target current database is measured in the laboratory and corresponds to the model of the fan. For example, the model of the fan is A. The target speed of the fan is 500. In the target current database corresponding to model A, the target current corresponding to the target speed of 500 is 0.5A. Another example: the model of the fan is B. The target speed of the fan is 500. In the target current database corresponding to model B, the target current corresponding to the target speed of 500 is 1A.
[0044] Furthermore, the air conditioner determines the cause of the failure of the indoor fan according to the real-time rotation speed and the real-time current, including: when the real-time rotation speed is less than the target rotation speed and the real-time current is greater than the target current, the air conditioner determines that the rotation of the blades of the indoor fan is severely obstructed. When the air conditioner determines that the rotation of the blades of the indoor fan is severely obstructed, the air conditioner sends a preset first fault cause to a preset user terminal to remind the user that the rotation of the blades of the indoor fan is severely obstructed. In this way, when the real-time rotation speed is less than the target rotation speed and the real-time current is greater than the target current, it can be accurately determined that the failure of the indoor fan is that the rotation of the blades of the indoor fan is severely obstructed. This allows maintenance personnel to repair the indoor fan of the air conditioner with respect to the blades whose rotation is severely obstructed, thereby reducing the difficulty of repairing the fan.
[0045] The preset first fault cause indicates that the rotation of the blades of the internal fan is severely obstructed.
[0046] Furthermore, when the air conditioner determines that the rotation of the blades of the indoor fan is seriously blocked, the air conditioner further includes: the air conditioner obtains a first repair measure corresponding to a preset first fault cause, and the air conditioner sends the first repair measure to a preset user terminal.
[0047] The first repair measure corresponding to the first fault cause is to specifically check the faults of the fan and the bearing.
[0048] In some embodiments, the real-time speed is less than the target speed and the real-time current is greater than the target current, that is, the current input of the internal fan is large, the circuit load is large, and the speed is slow, that is, the rotation of the fan blades is seriously hindered.
[0049] Combination Figure 2 As shown, the embodiment of the present disclosure provides another method for controlling an air conditioner, comprising:
[0050] Step S201, the air conditioner obtains the real-time rotation speed of the indoor fan and the real-time current of the motor. The indoor fan includes a motor.
[0051] Step S202: the air conditioner obtains a target rotation speed of the indoor fan.
[0052] Step S203: the air conditioner obtains a target current corresponding to the target speed.
[0053] Step S204: When the real-time rotation speed is less than the target rotation speed and the real-time current is greater than the target current, the air conditioner determines that the internal fan is faulty.
[0054] Step S205: When the real-time rotation speed of the air conditioner is less than the target rotation speed and the real-time current is greater than the target current, it is determined that the rotation of the blades of the indoor fan is seriously obstructed.
[0055] Step S206: When the air conditioner determines that the rotation of the blades of the indoor fan is seriously blocked, it obtains a first repair measure corresponding to a preset first fault cause. The preset first fault cause indicates that the rotation of the blades of the indoor fan is seriously blocked.
[0056] Step S207: the air conditioner sends the preset first fault cause and the first repair measure corresponding to the first fault cause to a preset user terminal.
[0057] According to the method for controlling an air conditioner provided by the embodiment of the present disclosure, the real-time rotation speed of the indoor fan and the real-time current of the motor are obtained, and then the target rotation speed of the indoor fan and the target current corresponding to the target rotation speed are obtained. When the real-time rotation speed is less than the target rotation speed and the real-time current is greater than the target current, the indoor fan is determined to be faulty, and the rotation of the fan blades of the indoor fan is determined to be seriously obstructed. Then, the first repair measure corresponding to the first fault cause representing the serious obstruction of the rotation of the fan blades of the indoor fan is obtained, and the first fault cause and the first repair measure are sent to a preset user terminal. In this way, when the real-time rotation speed is less than the target rotation speed and the real-time current is greater than the target current, the indoor fan is determined to be faulty, and the rotation of the fan blades of the indoor fan is determined to be seriously obstructed. Then, the first fault cause representing the serious obstruction of the rotation of the fan blades of the indoor fan and the first repair measure corresponding to the first fault cause are sent to a preset user terminal. This enables the user to promptly repair the indoor fan according to the fault cause of the serious obstruction of the rotation of the fan blades, thereby reducing the difficulty of repairing the indoor fan.
[0058] Optionally, the air conditioner determines whether the indoor fan is faulty according to the real-time rotation speed and the real-time current, including: the air conditioner obtains a target rotation speed of the indoor fan. The air conditioner obtains a target current corresponding to the target rotation speed. The air conditioner determines that the indoor fan is faulty when the real-time rotation speed is less than the target rotation speed and the real-time current is less than the target current. In this way, it is possible to accurately determine that the indoor fan is faulty when the real-time rotation speed is less than the target rotation speed and the real-time current is less than the target current.
[0059] Furthermore, the air conditioner determines the cause of the failure of the indoor fan according to the real-time rotation speed and the real-time current, including: when the real-time rotation speed is less than the target rotation speed and the real-time current is less than the target current, the air conditioner determines that the connection between the blades of the indoor fan and the motor is loose. When the air conditioner determines that the connection between the blades of the indoor fan and the motor is loose, the air conditioner sends a preset second fault cause to a preset user terminal to remind the user that the rotation of the blades of the indoor fan is blocked. In this way, when the real-time rotation speed is less than the target rotation speed and the real-time current is less than the target current, it can be accurately determined that the failure of the indoor fan is the loose connection between the blades of the indoor fan and the motor. This allows maintenance personnel to repair the indoor fan of the air conditioner based on the loose connection between the blades of the fan and the motor, thereby reducing the difficulty of repairing the fan.
[0060] The preset second fault cause indicates that the connection between the blades of the internal fan and the motor is loose.
[0061] Furthermore, when the air conditioner determines that the connection between the blades of the indoor fan and the motor is loose, the air conditioner further includes: the air conditioner obtains a second repair measure corresponding to a preset second fault cause, and the air conditioner sends the second repair measure to a preset user terminal.
[0062] The second repair measure corresponding to the second fault cause is to strengthen the connection between the motor and the fan blades.
[0063] In some embodiments, the real-time speed is less than the target speed and the real-time current is less than the target current, that is, the current input of the internal fan is small, the circuit load is small, and the speed is slow, so the connection between the fan blades and the motor of the internal fan is loose, and there is an occasional idling problem.
[0064] Combination Figure 3 As shown, the embodiment of the present disclosure provides another method for controlling an air conditioner, comprising:
[0065] Step S301, the air conditioner obtains the real-time rotation speed of the indoor fan and the real-time current of the motor. The indoor fan includes a motor.
[0066] Step S302: the air conditioner obtains a target rotation speed of the indoor fan.
[0067] Step S303: the air conditioner obtains a target current corresponding to the target speed.
[0068] Step S304: When the real-time rotation speed is less than the target rotation speed and the real-time current is less than the target current, the air conditioner determines that the internal fan is faulty.
[0069] Step S305 , when the real-time rotation speed is less than the target rotation speed and the real-time current is less than the target current, the air conditioner determines that the connection between the blades of the indoor fan and the motor is loose.
[0070] Step S306: When the air conditioner determines that the connection between the fan blades and the motor of the indoor fan is loose, it obtains a second repair measure corresponding to a preset second fault cause. The preset second fault cause indicates that the connection between the fan blades and the motor of the indoor fan is loose.
[0071] Step S307: the air conditioner sends the preset second fault cause and the second repair measure corresponding to the second fault cause to the preset user terminal.
[0072] According to the method for controlling an air conditioner provided by the embodiment of the present disclosure, the real-time rotation speed of the indoor fan and the real-time current of the motor are obtained, and then the target rotation speed of the indoor fan and the target current corresponding to the target rotation speed are obtained. When the real-time rotation speed is less than the target rotation speed and the real-time current is less than the target current, the indoor fan is determined to be faulty, and the connection between the blades of the indoor fan and the motor is determined to be loose. Then, the second repair measure corresponding to the second fault cause representing the loose connection between the blades of the indoor fan and the motor is obtained, and the second fault cause and the second repair measure are sent to a preset user terminal. In this way, when the real-time rotation speed is less than the target rotation speed and the real-time current is less than the target current, the indoor fan is determined to be faulty, and the connection between the blades of the indoor fan and the motor is determined to be loose. Then, the second fault cause representing the loose connection between the blades of the indoor fan and the motor and the second repair measure corresponding to the second fault cause are sent to a preset user terminal. This allows the user to promptly repair the indoor fan for the fault cause of the loose connection between the blades of the indoor fan and the motor, thereby reducing the difficulty of repairing the indoor fan.
[0073] Optionally, the air conditioner determines whether the indoor fan is faulty according to the real-time rotation speed and the real-time current, including: the air conditioner obtains a target rotation speed of the indoor fan. The air conditioner obtains a target current corresponding to the target rotation speed. The air conditioner determines that the indoor fan is faulty when the real-time rotation speed is equal to a preset rotation speed threshold and the real-time current is less than the target current. In this way, it is possible to accurately determine that the indoor fan is faulty when the real-time rotation speed is equal to the preset rotation speed threshold and the real-time current is less than the target current.
[0074] The preset speed threshold is 0.
[0075] Furthermore, the air conditioner determines the fault cause of the indoor fan according to the real-time rotation speed and the real-time current, including: the air conditioner determines that the motor of the indoor fan is idling when the real-time rotation speed is equal to the preset rotation speed threshold and the real-time current is less than the target current. When the air conditioner determines that the motor of the indoor fan is idling, the air conditioner sends the preset third fault cause to the preset user terminal to remind the user that the motor of the indoor fan is idling. In this way, it is possible to accurately determine that the motor of the indoor fan is idling when the real-time rotation speed is equal to the preset rotation speed threshold and the real-time current is less than the target current. This allows maintenance personnel to repair the indoor fan of the air conditioner with respect to the idling motor, thereby reducing the difficulty of repairing the fan.
[0076] The preset third fault cause indicates that the motor of the internal fan is idling.
[0077] Furthermore, when the air conditioner determines that the motor of the indoor fan is idling, the air conditioner further includes: the air conditioner obtains a third repair measure corresponding to a preset third fault cause, and the air conditioner sends the third repair measure to a preset user terminal.
[0078] The third repair measure corresponding to the third fault cause is to check whether the fixing screws between the fan blades and the motor have fallen off.
[0079] In some embodiments, the real-time speed is equal to the preset speed threshold and the real-time current is less than the target current. That is, the current input of the internal fan motor is small, the circuit load is small, and the speed is 0. It can be seen that the motor is rotating but the blades of the internal fan are not rotating. The motor of the internal fan is idling.
[0080] Combination Figure 4 As shown, the embodiment of the present disclosure provides another method for controlling an air conditioner, comprising:
[0081] Step S401, the air conditioner obtains the real-time rotation speed of the indoor fan and the real-time current of the motor. The indoor fan includes a motor.
[0082] Step S402: the air conditioner obtains a target rotation speed of the indoor fan.
[0083] Step S403: the air conditioner obtains a target current corresponding to the target speed.
[0084] Step S404: the air conditioner determines that the internal fan is faulty when the real-time rotation speed is equal to the preset rotation speed threshold and the real-time current is less than the target current.
[0085] Step S405 , the air conditioner determines that the motor of the indoor fan is idling when the real-time rotation speed is equal to the preset rotation speed threshold and the real-time current is less than the target current.
[0086] Step S406: When the air conditioner determines that the motor of the indoor fan is idling, it obtains a third repair measure corresponding to a preset third fault cause. The preset third fault cause indicates that the motor of the indoor fan is idling.
[0087] Step S407: the air conditioner sends the preset third fault cause and the third repair measure corresponding to the third fault cause to the preset user terminal.
[0088] The method for controlling an air conditioner provided by the embodiment of the present disclosure is adopted, by obtaining the real-time speed of the indoor fan and the real-time current of the motor, and then obtaining the target speed of the indoor fan and the target current corresponding to the target speed. When the real-time speed is equal to the preset speed threshold and the real-time current is less than the target current, the indoor fan fault is determined, and the motor of the indoor fan is determined to be idling. Then the third repair measure corresponding to the third fault cause characterizing the idling of the motor of the indoor fan is obtained, and the third fault cause and the third repair measure are sent to the preset user terminal. In this way, the indoor fan fault can be determined when the real-time speed is equal to the preset speed threshold and the real-time current is less than the target current, and the motor of the indoor fan is determined to be idling. Then the third fault cause characterizing the idling of the motor of the indoor fan and the third repair measure corresponding to the third fault cause are sent to the preset user terminal. The user can promptly repair the indoor fan according to the fault cause of the motor idling, thereby reducing the difficulty of repairing the indoor fan.
[0089] Optionally, the air conditioner determines whether the indoor fan is faulty according to the real-time rotation speed and the real-time current, including: the air conditioner obtains a target rotation speed of the indoor fan. The air conditioner obtains a target current corresponding to the target rotation speed. The air conditioner determines that the indoor fan is faulty when the real-time rotation speed is equal to the target rotation speed and the real-time current is greater than the target current. In this way, it can be accurately determined that the indoor fan is faulty when the real-time rotation speed is equal to the target rotation speed and the real-time current is greater than the target current.
[0090] Furthermore, the air conditioner determines the cause of the failure of the indoor fan according to the real-time rotation speed and the real-time current, including: when the real-time rotation speed is equal to the target rotation speed and the real-time current is greater than the target current, the air conditioner determines that the rotation of the blades of the indoor fan is slightly obstructed. When the air conditioner determines that the rotation of the blades of the indoor fan is slightly obstructed, the air conditioner sends the preset fourth fault cause to the preset user terminal to remind the user that the rotation of the blades of the indoor fan is slightly obstructed. In this way, when the real-time rotation speed is equal to the target rotation speed and the real-time current is greater than the target current, it can be accurately determined that the failure of the indoor fan is that the rotation of the blades of the indoor fan is slightly obstructed. This allows maintenance personnel to repair the indoor fan of the air conditioner with respect to the blades whose rotation is slightly obstructed, thereby reducing the difficulty of repairing the fan.
[0091] The preset fourth fault cause indicates that the rotation of the blades of the internal fan is slightly obstructed.
[0092] Furthermore, when the air conditioner determines that the rotation of the blades of the indoor fan is slightly obstructed, the air conditioner further includes: the air conditioner obtains a fourth repair measure corresponding to a preset fourth fault cause, and the air conditioner sends the fourth repair measure to a preset user terminal.
[0093] The fourth repair measure corresponding to the fourth fault cause is to clean the fan blades and / or replenish the lubricating oil of the bearings.
[0094] In some embodiments, the real-time speed is equal to the target speed and the real-time current is greater than the target current, that is, the current input of the internal fan is large, the circuit load is large, and the speed does not change, that is, the rotation of the fan blades is slightly obstructed.
[0095] Combination Figure 5 As shown, the embodiment of the present disclosure provides another method for controlling an air conditioner, comprising:
[0096] Step S501, the air conditioner obtains the real-time rotation speed of the indoor fan and the real-time current of the motor. The indoor fan includes a motor.
[0097] Step S502: the air conditioner obtains a target rotation speed of the indoor fan.
[0098] Step S503: the air conditioner obtains a target current corresponding to the target speed.
[0099] Step S504: the air conditioner determines that the internal fan is faulty when the real-time speed is equal to the target speed and the real-time current is greater than the target current.
[0100] Step S505 , when the real-time rotation speed is equal to the target rotation speed and the real-time current is greater than the target current, the air conditioner determines that the rotation of the blades of the indoor fan is slightly obstructed.
[0101] Step S506: When the air conditioner determines that the rotation of the blades of the indoor fan is slightly obstructed, it obtains a fourth repair measure corresponding to a preset fourth fault cause. The preset fourth fault cause indicates that the rotation of the blades of the indoor fan is slightly obstructed.
[0102] Step S507: the air conditioner sends the preset fourth fault cause and the fourth repair measure corresponding to the fourth fault cause to the preset user terminal.
[0103] According to the method for controlling an air conditioner provided by the embodiment of the present disclosure, the real-time rotation speed of the indoor fan and the real-time current of the motor are obtained, and then the target rotation speed of the indoor fan and the target current corresponding to the target rotation speed are obtained. When the real-time rotation speed is equal to the target rotation speed and the real-time current is greater than the target current, the indoor fan is determined to be faulty, and the rotation of the blades of the indoor fan is determined to be slightly obstructed. Then the fourth repair measure corresponding to the fourth fault cause representing the slight or severe obstruction of the blades of the indoor fan is obtained, and the fourth fault cause and the fourth repair measure are sent to a preset user terminal. In this way, when the real-time rotation speed is equal to the target rotation speed and the real-time current is greater than the target current, the indoor fan is determined to be faulty, and the rotation of the blades of the indoor fan is determined to be slightly obstructed. Then the fourth fault cause representing the slight obstruction of the rotation of the blades of the indoor fan and the fourth repair measure corresponding to the fourth fault cause are sent to the preset user terminal. This allows the user to promptly repair the indoor fan for the fault cause of the slight obstruction of the rotation of the blades, thereby reducing the difficulty of repairing the indoor fan.

The air conditioner obtains a target current corresponding to the target rotation speed. The air conditioner determines that the indoor fan is not faulty when the real-time rotation speed is greater than the target rotation speed, the real-time rotation speed is equal to the target rotation speed and the real-time current is less than or equal to the target current, or the real-time rotation speed is equal to a preset rotation speed threshold and the real-time current is less than or equal to the target current.
