[0002] At present, there are bumps on the road during transportation before the first installation of the wall-mounted air conditioner. In order to prevent the indoor fan configured in the indoor unit of the wall-mounted air conditioner from being damaged due to bumps during operation, before leaving the factory, the staff will insert an anti-rotation pad at the air outlet of the indoor unit so that the anti-rotation pad is stuck in the indoor fan. After the transport personnel transported the wall-mounted air conditioner to the installation area, there was a malfunction in which the indoor fan did not rotate after the wall-mounted air conditioner was powered on because the installer did not remove the anti-rotation pad in time.

[0005] For the failure of indoor fans to rotate due to anti-rotation pads, manual troubleshooting is required, which is difficult. Summary of the invention

[0006] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical components or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0007] The embodiments of the present disclosure provide a detection method, device, air conditioner and storage medium for a wall-mounted air conditioner, so as to automatically detect the fault that causes the indoor fan to not rotate for the first time installed wall-mounted air conditioner, thereby reducing the difficulty of troubleshooting.

[0008] In some embodiments, the wall-mounted indoor unit is equipped with an indoor fan and an air guide plate, and the method includes: when the wall-mounted indoor unit is powered on for the first time, controlling the indoor fan to start and controlling the air guide plate to close; obtaining the operating status of the indoor fan within a preset time period; and when the operating status indicates that the indoor fan is stuck within the preset time period, determining that the anti-rotation component provided in the indoor fan has not been removed.

[0009] In some embodiments, the device includes a processor and a memory storing program instructions, and the processor is configured to execute the aforementioned detection method for a wall-mounted air conditioner when running the program instructions.

[0010] In some embodiments, the air conditioner includes: a wall-mounted indoor unit equipped with an indoor fan and an air guide plate; and the detection device for the wall-mounted indoor unit as described above.

[0011] In some embodiments, the storage medium stores program instructions, and when the program instructions are run, they execute the aforementioned detection method for the wall-mounted air conditioner.

[0012] The detection method, device, air conditioner and storage medium for a wall-mounted air conditioner provided by the embodiments of the present disclosure can achieve the following technical effects:

[0013] When the wall-mounted indoor unit is powered on for the first time, the processor controls the indoor fan to start and controls the air guide plate to close, so as to prevent external airflow from entering the air duct of the indoor fan through the air guide plate and interfering with subsequent detection. The processor obtains the operating status of the indoor fan within a preset time. If it is determined that the indoor fan is stuck within the preset time, it indicates that an anti-rotation component is stuck in the indoor fan, thereby determining that the anti-rotation component provided in the indoor fan has not been removed.

[0031] 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.

[0035] 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.

[0036] 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.

[0037] During transportation before the first installation of the wall-mounted air conditioner, there are bumps on the road. In order to prevent the indoor fan configured in the indoor unit of the wall-mounted air conditioner from being damaged due to bumps during operation, before leaving the factory, the staff will insert an anti-rotation pad at the air outlet of the indoor unit so that the anti-rotation pad is stuck in the indoor fan. After the transport personnel transported the wall-mounted air conditioner to the installation area, there was a malfunction in which the indoor fan did not rotate after the wall-mounted air conditioner was powered on because the installer did not remove the anti-rotation pad in time.

[0038] Since there are many fault factors that may cause the indoor fan to not rotate, after installing the wall-mounted air conditioner, troubleshooting the factors that may cause the indoor fan to not rotate will inevitably increase the difficulty of the installer's work and affect the installation efficiency.

[0039] Based on the above technical problems, the embodiments of the present disclosure disclose an air conditioner, including a wall-mounted indoor unit and an outdoor unit. Figure 1 This is a longitudinal section view of a wall-mounted indoor unit. Figure 1 As shown, the wall-mounted indoor unit is equipped with an indoor fan 10 and an air guide plate 20.

[0040] The indoor fan 10 is provided with a rotating member 10a, and the rotating member 10a can block the light signal when being driven. The indoor fan 10 can be a cross-flow fan. When the indoor fan is a cross-flow fan, the rotating member 10a is a toothed blade. Among them, an anti-rotation member 40 can be provided between any adjacent rotating members 10a of the indoor fan 10.

[0041] The side of the air guide plate 20 facing the indoor fan is provided with a light emitting module 301 for emitting light signals. Optionally, the air guide plate 20 is provided with a mounting bracket 20a. The light emitting module 301 is mounted on the mounting bracket 20a.

[0042] An optical receiving module 302 for receiving an optical signal emitted by the optical transmitting module 301 is arranged in the air duct of the indoor fan 10. The connecting line formed by the optical transmitting module 301 and the optical receiving module 302 is perpendicular to the axis of the indoor fan 10. Optionally, the connecting line formed by the optical transmitting module 301 and the optical receiving module 302 is coplanar and perpendicular to the axis of the indoor fan 10. As an example, the intersection of the connecting line formed by the optical transmitting module 301 and the optical receiving module 302 and the axis of the cross-flow fan is located at the center of the axis of the cross-flow fan. Optionally, the connecting line formed by the optical transmitting module 301 and the optical receiving module 302 is skewed and perpendicular to the axis of the indoor fan 10. In this way, when the indoor fan 10 is assembled in place and operates periodically, the optical receiving module 302 can periodically receive the optical signal emitted by the optical transmitting module 301, which is conducive to the accurate detection of the operation of the indoor fan 10.

[0043] Figure 2 A schematic diagram showing the structure of an anti-rotation component. Figure 3 The figure shows the installation position of the anti-rotation part. The arrow indicates the approximate installation position of the anti-rotation part. Figure 2 and Figure 3 As shown, the end 40a of the anti-rotation member 40 is inserted into the rotating member 10a of the indoor fan 10 to form a locking. As an example, the anti-rotation member 40 can be an anti-rotation pad. In the case where the indoor fan is a cross-flow fan, the end 40a of the anti-rotation pad is inserted between any two adjacent teeth of the cross-flow fan. Optionally, the anti-rotation member 40 is a strip-shaped structure. The anti-rotation member 40 can be made of foam material or rubber material.

[0044] Combination Figure 4 As shown, the embodiment of the present disclosure provides a detection method for a wall-mounted indoor unit, comprising:

[0045] S01, when the wall-mounted indoor unit is powered on for the first time, the processor controls the indoor fan to start and controls the air guide plate to close.

[0046] S02, the processor obtains the operating status of the indoor fan within a preset time period.

[0047] S03, when the processor is in a running state indicating that the indoor fan is stuck for a preset time period, it is determined that the anti-rotation component provided in the indoor fan has not been removed.

[0048] Using the detection method for a wall-mounted indoor unit provided in the embodiment of the present disclosure, when the wall-mounted indoor unit is powered on for the first time, the processor controls the indoor fan to start and controls the air guide plate to close, so as to prevent external airflow from entering the air duct of the indoor fan through the air guide plate and interfering with subsequent detection. The processor obtains the operating status of the indoor fan within a preset time. If it is determined that the indoor fan is stuck within the preset time, it indicates that an anti-rotation component is stuck in the indoor fan, thereby determining that the anti-rotation component provided in the indoor fan has not been removed. Therefore, the embodiment of the present disclosure can automatically detect the fault of the anti-rotation component not being removed for a wall-mounted air conditioner that is installed for the first time, which helps to reduce the difficulty of troubleshooting the aforementioned fault.

[0049] It should be noted that the execution subject of the embodiment of the present disclosure is a processor. The processor can be configured in the air conditioner, or in a server that is connected to the air conditioner for communication. The embodiment of the present disclosure does not make any specific limitation on this.

[0050] Optionally, combined Figure 5 As shown, determine whether the indoor fan is stuck within the preset time in the following manner:

[0051] S11, the processor controls the optical transmission module to periodically transmit an optical signal within a preset time period.

[0052] S12: When there is a time interval during which the optical receiving module does not receive an optical signal in a plurality of adjacent preset periods, the processor determines that the indoor fan is stuck for a preset time period.

[0053] The preset period represents the period value of the optical signal emitted by the optical emission module. The preset duration may be an integer multiple of the preset period. As an example, the preset duration is equal to 20 times or 40 times the preset period. The time interval is greater than the preset period. As an example, the time interval is much greater than the preset period.

[0054] In this way, since the indoor fan 10 is equipped with a rotating part 10a, and the rotating part 10a can block the light signal when being driven, and the indoor fan 10 usually operates periodically, therefore, when the anti-rotation part is not placed at the rotating part 10a of the indoor fan 10, the light receiving module 302 must also periodically receive the light signal. When the anti-rotation part is placed at the rotating part 10a of the indoor fan 10, the rotating part 10a is stopped by the anti-rotation part when being driven to rotate. As a result, the light receiving module 302 periodically receives the light signal while there is a certain time interval in which the light signal is not received. That is, in multiple adjacent preset cycles, the light receiving module has a time interval in which the light signal is not received. Thus, it can be determined that the indoor fan has a jamming phenomenon within a preset time length. Therefore, through the situation that the light receiving module receives the light signal, it is possible to realize automatic detection of whether the indoor fan has a jamming within a preset time length, which is conducive to realizing automatic detection of faults caused by the anti-rotation part not being removed.

[0055] In addition, the optical transmitting module 301 and the optical receiving module 302 are small in size, and in the process of transmitting or receiving optical signals, the weight of the original structure of the indoor fan and the air guide plate will not be increased, and the operation of the indoor fan and the air outlet of the air guide plate will not be interfered. Therefore, the above detection method has good universality and is easy to promote and use.

[0056] Optionally, the time interval during which the optical receiving module does not receive an optical signal in multiple adjacent preset periods may be a unique time interval during which the optical receiving module does not receive an optical signal in multiple adjacent preset periods, and the time interval is much longer than the preset period.

[0057] The unique time interval is caused by the rotating part being stopped by the anti-rotation part.

[0058] Optionally, the optical transmitting module includes an infrared transmitting end for transmitting infrared light, and the optical receiving module includes an infrared receiving end for receiving infrared light.

[0059] In this way, by configuring an infrared transmitting end in the optical transmitting module and configuring an infrared receiving end in the optical receiving module, the indoor fan jamming phenomenon can be detected according to the reception of infrared light. Infrared light detection has the advantages of high sensitivity and fast response. Therefore, the embodiment of the present disclosure is conducive to improving the sensitivity of indoor fan jamming phenomenon detection through infrared light detection.

[0060] Combination Figure 6 As shown, the embodiment of the present disclosure also provides a detection method for a wall-mounted indoor unit, comprising:

[0061] S21, when the wall-mounted indoor unit is powered on for the first time, the processor controls the indoor fan to start and controls the air guide plate to close.

[0062] S22, the processor controls the indoor fan to run in a preset direction.

[0063] S23, when the processor determines that the indoor fan is blocked when running in a preset direction, it determines that the blockage is caused by improper assembly of the indoor fan or the anti-rotation component is not removed.

[0064] S24, the processor obtains the operating status of the indoor fan within a preset time period.

[0065] S25, when the processor is in the running state and indicates that the indoor fan is stuck for a preset time period, it is determined that the anti-rotation component provided in the indoor fan has not been removed.

[0066] Using the detection method for a wall-mounted indoor unit provided by the embodiment of the present disclosure, under normal circumstances, when the indoor fan is improperly assembled or the anti-rotation part is not removed, the indoor fan will be blocked when rotating forward or reverse. Therefore, the processor controls the indoor fan to run in a preset direction to determine whether there are other fault causes other than improper assembly and the anti-rotation part not being removed. In this way, the cause of the fault can be basically locked according to the situation that the indoor fan runs in the preset direction, thereby improving the efficiency of troubleshooting.

[0067] Optionally, the preset direction includes a direction corresponding to forward operation of the indoor fan.

[0068] Optionally, combined Figure 7 As shown, when the processor determines that the indoor fan is blocked when running in a preset direction, it determines that the blockage is caused by improper assembly of the indoor fan or the anti-rotation part is not removed, including:

[0069] S31, when the processor determines that the indoor fan is blocked when running in a preset direction, the processor controls the indoor fan to run in the reverse direction in the preset direction.

[0070] S32, when the processor determines that the indoor fan is blocked by running in the reverse direction in a preset direction, it determines that the blockage is caused by improper assembly of the indoor fan or failure to remove the anti-rotation component.

[0071] In this way, when the indoor fan is improperly assembled or the anti-rotation part is not removed, the indoor fan will be blocked when rotating forward or reverse. For this reason, the disclosed embodiment controls the indoor fan to rotate in a preset direction and then controls it to rotate in the preset direction in reverse. If both of them are blocked, it indicates that the indoor fan is improperly assembled and falls off or the anti-rotation part is not removed, which leads to the blockage. This is conducive to improving the reliability of troubleshooting.

[0072] Optionally, combined Figure 8 As shown, the processor determines that the indoor fan is blocked in a preset direction or in a reverse direction of the preset direction in the following manner:

[0073] S41, the processor obtains the speed value of the indoor fan running in a preset direction or in the reverse direction of the preset direction.

[0074] S42, the processor determines whether the rotation speed of the indoor fan has a decreasing trend; if so, execute S43.

[0075] S43, the processor determines that the indoor fan is blocked.

[0076] This will help improve the reliability of indoor fan jam detection.

[0077] Optionally, the rotation speed of the indoor fan is determined to have a decreasing trend in the following manner:

[0078] The speed value at the current moment and the speed value at the target moment are less than zero.

[0079] The target time represents the previous sampling time that is adjacent to the current time.

[0080] In this way, when the rotation speed value at the current moment and the rotation speed value at the target moment are less than zero, it indicates that the rotation speed value continues to decrease, that is, it is determined that the rotation speed of the indoor fan has a decreasing trend.

[0081] Optionally, after the processor determines that the anti-rotation component disposed in the indoor fan is removed, the method further includes:

[0082] The processor outputs a prompt message indicating that the anti-rotation piece has not been taken out.

[0083] In this way, by outputting a prompt message that the anti-rotation part has not been taken out, the installer can take out the anti-rotation part in time, which is helpful to reduce the difficulty of manual troubleshooting and improve installation efficiency.

[0084] Optionally, the prompt information may be audio information, text information, or image information. As an example, the wall-mounted indoor unit is also equipped with a display screen. The processor outputs the text information of "anti-rotation component failure" through the display screen. As another example, the wall-mounted indoor unit is equipped with an audio playback device. The processor broadcasts the audio information of "anti-rotation component failure" through the audio playback device.

[0085] In practical applications, the detection method for a wall-mounted indoor unit specifically performs the following steps:

[0086] S51: When the wall-mounted indoor unit is powered on for the first time, the processor controls the indoor fan to start and controls the air guide plate to close.

[0087] S52, the processor controls the indoor fan to run in a preset direction.

[0088] S53, when the processor determines that the indoor fan is blocked during forward operation, the processor controls the indoor fan to rotate in reverse. When the processor determines that the indoor fan is blocked during reverse operation, the processor determines that the indoor fan is blocked due to improper assembly of the indoor fan, the fan falling off, or the anti-rotation part not being removed.

[0089] S54, the processor obtains the operating status of the indoor fan within a preset time period.

[0090] S55, when the processor is in the running state and indicates that the indoor fan is stuck for a preset time period, it is determined that the anti-rotation component provided in the indoor fan has not been removed.

[0091] S56, the processor controls the optical transmission module to periodically transmit optical signals within a preset duration. The processor determines that the indoor fan is stuck within the preset duration when the optical receiving module does not receive the optical signal for a uniquely long time interval within multiple adjacent preset periods.

[0092] S57, the processor determines that the anti-rotation component provided in the indoor fan has not been removed, and displays a text message of "anti-rotation component failure" on the display screen of the wall-mounted indoor unit.
