[0037] The preferred embodiments of the present application will be described below with reference to the accompanying drawings. Those skilled in the art will appreciate that the embodiments are only used to explain the technical principles of the present application, and are not intended to limit the scope of protection of the present application. For example, although the steps in the following examples are described in a certain order, those skilled in the art can understand that, in order to achieve the effect of the present embodiment, the steps do not have to be executed in such an order, and they can be executed simultaneously (in parallel) or in a reversed order, and these simple changes are within the scope of protection of the present application.

[0038] Figure 1 is a schematic flow chart of a control method of an air conditioner according to an embodiment of the present application. As shown in Figure 1 , the control method of an air conditioner according to an embodiment of the present application comprises the following steps:

[0039] S100, in response to a noise reduction instruction of the air conditioner, the air conditioner is operated according to user demand, a first noise DB before the indoor unit of the air conditioner is started is obtained, and a second noise DB1 when the indoor unit of the air conditioner is started is obtained;

[0040] S200, the second noise DB1 is compared with the first noise DB, and a first comparison result is obtained;

[0041] S300, according to the first comparison result, the noise of the indoor unit of the air conditioner is selectively processed.

[0042] In the above-mentioned embodiments, the present application compares the second noise DB1 with the first noise DB, obtains a first comparison result, and selectively processes the noise of the indoor unit of the air conditioner according to the first comparison result, which can reduce the noise generated by the air conditioner during operation and improve user experience satisfaction.

[0043] Figure 2 is a schematic flow chart of the step of "selectively processing the noise of the indoor unit of the air conditioner according to the first comparison result" according to an embodiment of the present application. As shown in Figure 2 , in the preferred embodiments of the control method of an air conditioner described above, the step of "selectively processing the noise of the indoor unit of the air conditioner according to the first comparison result" comprises:

[0044] S310, if DB1-DB≤M, it is determined that the noise of the indoor unit of the air conditioner when it is started is normal, and the noise of the indoor unit of the air conditioner during operation is further detected and processed.

[0045] S320, if DB1-DB>M, it is determined that the noise of the air conditioner when it is started is not normal, because at this time the air conditioner has just started, the compressor has not started, the fan speed is 0, and only the rotation of the air deflector will produce noise, at this time the air conditioner will notify the user of the output conclusion, and the user will be notified to check the lubrication and working state of the air deflector.

[0046] Wherein, M is the first comparison threshold. In the preferred embodiment of the control method of the air conditioner, the first comparison threshold M is 3-5 decibels. For example, M is 3 decibels, and M can also be 4 decibels or 5 decibels.

[0047] For example, the obtained second noise DB1 is 50 decibels, the obtained first noise DB is 45 decibels, and M is 3 decibels. Then DB1-DB>M, 50-45>3, it is determined that the noise of the air conditioner when starting is abnormal, and at this time the user is informed to check the lubrication and working state of the air deflector.

[0048] For another example, the obtained second noise DB1 is 47 decibels, the obtained first noise DB is 45 decibels, and M is 3 decibels. Then DB1-DB>M, 47-45≤3, it is determined that the noise of the air conditioner when starting is normal, and further detection of the noise of the indoor unit of the air conditioner in operation is performed.

[0049] Figure 3 is a schematic flow chart of the step of "further detection of the noise of the indoor unit of the air conditioner in operation and processing" of an embodiment of the present application. As shown in Figure 3 If DB1-DB≤M, it is determined that the noise of the air conditioner when starting is normal. In the case of normal starting noise, analysis and comparison are performed under the silent speed. The air conditioner is first started in the silent mode, and at this time the fan speed of the indoor unit of the air conditioner is operated at the speed in the silent state. From the start of receiving the starting command, the noise sensor starts collecting the noise generated by the air conditioner until the air conditioner reaches the silent mode speed. Because of the protection of the air conditioner program for the supercooling and superheating of the compressor, when the air conditioner obtains the starting command, the compressor does not immediately operate, and generally the air conditioner compressor is involved in work after 90-120 seconds, and during this time the fan of the indoor unit of the air conditioner has reached the silent speed, and the detection is completed without interference from the system. At this time, the data read by the sensor is continuous noise, and if the initial detection noise is chaotic noise, the noise detection is stopped, and the air conditioner is normally operated according to the self-set program. The third noise DB2 of the fan of the indoor unit of the air conditioner at the silent speed is obtained.

[0050] As shown in Figure 3 In the preferred embodiment of the control method of the air conditioner, the step of "further detection of the noise of the indoor unit of the air conditioner in operation and processing" specifically includes:

[0051] S311 makes the air conditioner start the silent mode, and obtains the third noise DB2 of the air conditioner at the silent speed;

[0052] S312 compares the third noise DB2 with the second noise DB1, and obtains a second comparison result;

[0053] S313 selectively performs noise reduction processing on the indoor unit of the air conditioner according to the second comparison result.

[0054] Figure 4 is a schematic flow chart of the step of "selectively performing noise reduction processing on the indoor unit of the air conditioner according to the second comparison result" in an embodiment of the present application. As shown in Figure 4 , in the preferred embodiment of the control method of the air conditioner, the step of "selectively performing noise reduction processing on the indoor unit of the air conditioner according to the second comparison result" comprises:

[0055] S3131 if DB2-DB1≤N, it is determined that the noise of the indoor unit of the air conditioner is normal, and no noise reduction processing is performed on the air conditioner, wherein N is the second comparison threshold. The second comparison threshold N is 38 decibels-43 decibels. N can be 38 decibels, 39 decibels, 40 decibels, 41 decibels, 42 decibels or 43 decibels.

[0056] S3132 if N

[0057] S3133 if DB2-DB1>P, it is determined that the noise of the indoor unit of the air conditioner is too large when the indoor unit is running, and the air conditioner is controlled to stop and the user is notified to maintain the air conditioner, wherein P is the third comparison threshold. In the preferred embodiment of the control method of the air conditioner, the third comparison threshold P is 45 decibels-50 decibels. P can be 45 decibels, 46 decibels, 47 decibels, 48 decibels, 49 decibels or 50 decibels.

[0058] Figure 5 is a schematic flow chart of the step of "detecting the fan speed of the indoor unit of the air conditioner" in an embodiment of the present application. In the preferred embodiment of the control method of the air conditioner, as shown in Figure 5 , the step of "detecting the fan speed of the indoor unit of the air conditioner if N

[0059] S31321 if the current fan speed of the indoor unit of the air conditioner is less than or equal to the fan silent standard speed of the indoor unit of the air conditioner, it is determined that the noise of the indoor unit of the air conditioner is abnormal, and further detection is performed on whether the current of the fan motor of the circuit board is normal to perform noise reduction processing.

[0060] At this time, the current air conditioner indoor unit fan speed is low, but the noise is large, indicating that the fan speed does not meet the requirements and the transmission of the refrigerant sound is increased, which causes the air conditioner noise to increase.

[0061] The step of "further detecting whether the current input of the detection circuit board to the fan motor is normal to perform noise reduction processing" includes: detecting the current input of the detection circuit board to the fan motor of the indoor unit of the air conditioner,

[0062] If the current input is normal at this time, the fan motor of the indoor unit of the air conditioner needs to be demagnetized by power-off, and the fan motor of the indoor unit of the air conditioner is demagnetized and then powered on again.

[0063] If the current input is abnormal at this time, the fan motor of the indoor unit of the air conditioner needs to be powered off and then powered on to restore the factory settings.

[0064] In addition, the input current of the compressor can also be judged, only to confirm whether the input current of the compressor is the theoretical input value of the silent state, if not, the logic of the power-off and power-on recovery circuit board can be performed.

[0065] S31322 If the current air conditioner indoor unit fan speed > air conditioner indoor unit fan silent standard speed, the air conditioner indoor unit fan is reduced in speed. In this state, the indoor unit fan speed is first reduced, and then noise judgment is performed when the air conditioner indoor unit fan speed reaches the air conditioner indoor unit fan theoretical speed.

[0066] Taking a 1.5P indoor unit as an example, for example, the third noise value DB2 obtained is 75 decibels, the second noise value DB1 is 45 decibels, and N is 38 decibels, then DB2-DB1≤N, 75-45≤38, at this time it is determined that the indoor unit is running normally, and no noise reduction processing is performed on the air conditioner.

[0067] For example, the third noise value DB2 obtained is 87 decibels, the second noise value DB1 is 45 decibels, N is 38 decibels, and P is 45 decibels, then N<DB2-DB1≤P, 38<87-45≤45, at this time it is determined that the indoor unit of the air conditioner is running noise, and the detection of the fan speed of the indoor unit of the air conditioner is increased. If the current air conditioner indoor unit fan speed ≤ air conditioner indoor unit fan silent standard speed, the noise of the air conditioner indoor unit is abnormal, further detection of the current input of the detection circuit board to the fan motor is performed to perform noise reduction processing. If the fan speed > silent standard speed at this time, the air conditioner is reduced in speed. If the current air conditioner indoor unit fan speed > air conditioner indoor unit fan silent standard speed, the air conditioner indoor unit fan is reduced in speed.

[0068] For example, the acquired third noise value DB2 is 100 decibels, the second noise value DB1 is 45 decibels, and P is 45 decibels. If DB2-DB1>P, 100-45>45, it is determined that the noise of the indoor unit of the air conditioner is too large at this time, the air conditioner is stopped, and the air conditioner notifies the user to maintain to prevent accidents.

[0070] In the above-mentioned embodiment, the second noise DB1 is compared with the first noise DB, and a first comparison result is obtained. According to the first comparison result, the noise of the indoor unit of the air conditioner is selectively processed, so that the noise generated during the operation of the air conditioner can be reduced, and the user experience satisfaction can be improved.
