Description

Technical Field

[0001] This application relates to the field of air conditioner technology, such as a control method and apparatus for an air conditioner, an air conditioner, and a storage medium. Background Technology

[0002] Currently, all existing air conditioners are equipped with a self-cleaning function. During use, users can control the air conditioner to perform the self-cleaning operation by operating the self-cleaning mode on the remote control.

[0003] The relevant technology adopts the following technical solution: when the air conditioner is in self-cleaning mode, the total power of the air conditioner and the running time of the self-cleaning mode are both constant values.

[0004] As air conditioners are used for an extended period, their heat exchange performance tends to decline. Furthermore, the accumulation of dirt on the surfaces of the indoor and / or outdoor heat exchangers exacerbates this decline. If the self-cleaning mode is continued at a fixed power level and operating time after the air conditioner's heat exchange performance has deteriorated, incomplete self-cleaning will inevitably result.

[0005] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0006] The self-cleaning method of using a constant parameter value to achieve self-cleaning of the air conditioner does not take into account changes in the heat exchange performance of the air conditioner, resulting in low self-cleaning efficiency.

[0007] It should be noted that the information disclosed in the background section above 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 those skilled in the art. Summary of the Invention

[0008] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0009] This disclosure provides a control method, apparatus, air conditioner, and storage medium for an air conditioner to improve the self-cleaning efficiency of the air conditioner.

[0010] In some embodiments, the method includes: in response to a first control command for triggering the execution of a self-cleaning mode, acquiring tag information associated with the heat exchange efficiency decay rate of an indoor heat exchanger; if the tag information indicates that it is valid, acquiring the heat exchange efficiency decay rate; and determining and executing a target self-cleaning mode corresponding to the heat exchange efficiency decay rate based on the heat exchange efficiency decay rate.

[0011] In some embodiments, the apparatus includes a processor and a memory storing program instructions, wherein the processor is configured to execute the control method for an air conditioner as described above when the program instructions are executed.

[0012] In some embodiments, the air conditioner includes: an air conditioner body; and a control device for the air conditioner as described above, which is installed on the air conditioner body.

[0013] In some embodiments, the storage medium stores program instructions that, when executed, perform the control method for an air conditioner as described above.

[0014] The control method, apparatus, air conditioner, and storage medium for air conditioners provided in this disclosure can achieve the following technical effects:

[0015] When the air conditioner receives the first control command, it acquires tag information associated with the indoor heat exchange efficiency decay rate to determine whether the heat exchange efficiency decay rate is valid. If valid, it indicates that the acquired heat exchange efficiency decay rate reflects the air conditioner's heat exchange performance. Therefore, the air conditioner executes a target self-cleaning mode adapted to its heat exchange performance. Thus, this embodiment of the present disclosure can use the air conditioner's heat exchange performance as the basis for determining the target self-cleaning mode, enabling the execution of different self-cleaning modes for air conditioners with different heat exchange performances, making self-cleaning more thorough, thereby improving the execution efficiency of the air conditioner's self-cleaning mode.

[0027] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0029] Unless otherwise stated, the term "multiple" means two or more.

[0030] In this embodiment of the disclosure, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.

[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.

[0032] The term "correspondence" can refer to an association or binding relationship. The correspondence between A and B means that there is an association or binding relationship between A and B.

[0033] Combination Figure 1 As shown, this disclosure provides a control method for an air conditioner, including:

[0034] S01, the air conditioner responds to the first control command used to trigger the execution of the self-cleaning mode and obtains the tag information associated with the heat exchange efficiency decay rate of the indoor heat exchanger.

[0035] In this step, the heat exchange efficiency decay rate can reflect the heat exchange performance of the air conditioner.

[0036] S02, if the label information indicates that the air conditioner is valid, obtain the heat exchange efficiency attenuation rate.

[0037] S03, the air conditioner determines and executes the target self-cleaning mode corresponding to the heat exchange efficiency decay rate based on the heat exchange efficiency decay rate.

[0038] Using the control method for an air conditioner provided in this disclosure, when the air conditioner receives a first control command, it acquires tag information associated with the indoor heat exchange efficiency decay rate to determine whether the heat exchange efficiency decay rate is valid based on the tag information. If valid, it indicates that the acquired heat exchange efficiency decay rate reflects the heat exchange performance of the air conditioner. Therefore, the air conditioner executes a target self-cleaning mode adapted to its heat exchange performance. Thus, this disclosure can use the air conditioner's heat exchange performance as the basis for determining the target self-cleaning mode, enabling the execution of different self-cleaning modes for air conditioners with different heat exchange performances, making self-cleaning more thorough, thereby improving the execution efficiency of the air conditioner's self-cleaning mode.

[0039] Alternatively, the air conditioner determines the validity of the label information in the following ways:

[0040] The first control command is the received control command used to trigger the execution of the first self-cleaning mode.

[0041] Alternatively, the air conditioner may determine that the label information is invalid in the following ways:

[0042] If the air conditioner determines the tag information to be invalid when the first control command is used to trigger the execution of the Nth self-cleaning mode, and both the first control command and the previous control command that is sequentially consecutive to trigger the execution of the self-cleaning mode are used to trigger the execution of the self-cleaning mode, then N is greater than or equal to 2.

[0043] Therefore, if the air conditioner receives a control command to trigger the self-cleaning mode before receiving the control command to trigger the self-cleaning mode, the air conditioner's heat exchange performance will inevitably improve because the self-cleaning mode has already been executed. Correspondingly, the heat exchange efficiency decay rate will decrease. The heat exchange efficiency decay rate obtained in this case cannot accurately reflect the air conditioner's current heat exchange performance. Therefore, if the air conditioner receives a control command to trigger the self-cleaning mode before receiving the control command to trigger the self-cleaning mode, and the two control commands are sequential, the tag information is invalid.

[0044] In summary, when the first control command is a control command used to trigger the Nth self-cleaning mode, and both the first control command and the previous control command that is sequentially consecutive in time are used to trigger the self-cleaning mode, the tag information is determined to be invalid. However, when the first control command is a received control command used to trigger the first self-cleaning mode, the tag information is determined to be valid.

[0045] Optionally, the air conditioner determines and executes a target self-cleaning mode corresponding to the heat exchange efficiency decay rate based on the heat exchange efficiency decay rate, including:

[0046] When the heat exchange efficiency decay rate of the air conditioner is greater than or equal to the preset value, the first self-cleaning mode is determined and executed.

[0047] When the heat exchange efficiency decay rate of the air conditioner is less than the preset value, the second self-cleaning mode is determined and executed.

[0048] In this mode, the total power consumption of the first self-cleaning mode is greater than that of the second self-cleaning mode, and / or, the operating time of the first self-cleaning mode is greater than that of the second self-cleaning mode. The preset value is the heat exchange efficiency decay rate corresponding to the baseline duration.

[0049] Thus, when the heat exchange efficiency decay rate is greater than or equal to the preset value, it indicates that the heat exchange efficiency of the indoor heat exchanger is extremely low. The indoor heat exchanger is severely clogged, and in this case, the first self-cleaning mode is activated. Conversely, when the heat exchange efficiency decay rate is less than the preset value, it indicates that although the heat exchange efficiency of the indoor heat exchanger has decreased somewhat, the degree of cloggedness is moderate or mild, and in this case, the second self-cleaning mode is activated. The total power consumption of the first self-cleaning mode is greater than that of the second self-cleaning mode, and / or, the operating time of the first self-cleaning mode is greater than that of the second self-cleaning mode. Compared to the second self-cleaning mode, the first self-cleaning mode has a stronger self-cleaning effect.

[0050] Optionally, the air conditioner can be set to a powerful self-cleaning mode and a normal self-cleaning mode. The first self-cleaning mode is the powerful self-cleaning mode. The second self-cleaning mode is the normal self-cleaning mode.

[0051] Optionally, the reference duration is a preset multiple of the theoretical duration. The preset multiple is greater than or equal to 1.1 and less than or equal to 1.3. The theoretical duration represents the duration during which the air conditioner operates at its rated total power in cooling / heating mode after initial startup.

[0052] Since the indoor heat exchanger is generally free of dirt or clogs or is relatively clean after the air conditioner is first turned on, if the theoretical duration corresponding to the heat exchange efficiency decay rate is used as a reference value, it is very easy for the first self-cleaning mode to be continuously executed, i.e., continuous and uninterrupted self-cleaning or excessive self-cleaning. Therefore, this embodiment sets the reference duration to a preset multiple of the theoretical duration to appropriately increase the reference value, thereby reasonably and timely executing the corresponding self-cleaning mode.

[0053] Optionally, when the heat exchange efficiency decay rate of the air conditioner is greater than or equal to a preset value, a first self-cleaning mode is determined and executed, including:

[0054] The air conditioner increases the operating frequency of the compressor and / or increases the power of the indoor fan.

[0055] In this way, the air conditioner can shorten the running time of the self-cleaning mode by increasing the operating frequency of the compressor and / or increasing the power value of the indoor fan, thereby improving the efficiency of self-cleaning while providing powerful self-cleaning.

[0056] Optionally, when the heat exchange efficiency decay rate of the air conditioner is greater than or equal to a preset value, a first self-cleaning mode is determined and executed, including:

[0057] The air conditioner maintains a constant overall power output and increases the runtime of the self-cleaning mode.

[0058] In this way, the air conditioner can improve the self-cleaning effect by extending the running time of the self-cleaning mode.

[0059] It should be noted that increasing the compressor's operating frequency and / or increasing the indoor fan's power level provides a stronger self-cleaning effect than maintaining the air conditioner's overall power level and increasing the self-cleaning mode's operating time. In practical applications, this can be adjusted according to specific circumstances.

[0060] Combination Figure 2 As shown, this disclosure provides another control method for an air conditioner, including:

[0061] S11, the air conditioner responds to the second control command used to trigger the execution of the target mode and executes the target mode.

[0062] S12, the air conditioner obtains the operating status of the target mode.

[0063] S13, when the air conditioner indicates that the target mode operation has ended, update the label associated with the current heat exchange efficiency decay rate to be valid.

[0064] S14, the air conditioner responds to a first control command used to trigger the execution of the self-cleaning mode and obtains tag information associated with the heat exchange efficiency decay rate of the indoor heat exchanger.

[0065] S15, if the label information indicates that the air conditioner is valid, obtain the heat exchange efficiency attenuation rate.

[0066] S16, the air conditioner determines and executes the target self-cleaning mode corresponding to the heat exchange efficiency decay rate based on the heat exchange efficiency decay rate.

[0067] The target mode includes either cooling mode or heating mode.

[0068] Using the control method for an air conditioner provided in this disclosure, if the air conditioner receives a second control command to trigger a target mode, it executes the target mode and monitors the operating status of the target mode. Upon determining that the cooling mode or heating mode has ended, the tag associated with the current heat exchange efficiency decay rate is updated to be valid.

[0069] It should be noted that after an air conditioner operates in cooling or heating mode, foreign matter, such as dust and dirt, will adhere to the surface of the indoor heat exchanger. This reduces heat exchange efficiency, and the rate of efficiency degradation increases accordingly. Therefore, the rate of efficiency degradation obtained after the air conditioner has operated in cooling or heating mode, before receiving the first control command to trigger the initial self-cleaning mode, accurately reflects the current heat exchange performance of the air conditioner. In summary, if the air conditioner operates in cooling or heating mode and then receives the first control command to trigger the initial self-cleaning mode, the rate of efficiency degradation accurately reflects the current heat exchange performance of the air conditioner. Simultaneously, the label information is confirmed to be valid.

[0070] Combination Figure 3 As shown, this disclosure provides another control method for an air conditioner, including:

[0071] S21, the air conditioner responds to a first control command used to trigger the execution of the self-cleaning mode and obtains tag information associated with the heat exchange efficiency decay rate of the indoor heat exchanger.

[0072] S22, if the label information indicates that the air conditioner is valid, obtain the heat exchange efficiency attenuation rate.

[0073] S23, the air conditioner determines and executes the target self-cleaning mode corresponding to the heat exchange efficiency decay rate based on the heat exchange efficiency decay rate.

[0074] S24, the air conditioner obtains the operating status of the target self-cleaning mode.

[0075] S25, when the air conditioner indicates that self-cleaning has ended, updating the label information associated with the heat exchange efficiency degradation rate is invalid.

[0076] The control method for air conditioners provided in this disclosure inevitably improves the heat exchange performance of the air conditioner during the self-cleaning process. Consequently, the heat exchange efficiency decay rate decreases. Therefore, to improve the compatibility between the target self-cleaning mode and the air conditioner's heat exchange performance, the air conditioner updates the heat exchange efficiency decay rate label information to invalid at the end of the self-cleaning process.

[0077] Understandably, after the air conditioner completes this self-cleaning cycle, updating the tag information associated with the heat exchange efficiency degradation rate is invalid. Therefore, if the air conditioner receives another control command to trigger the self-cleaning mode after this cycle, and the two self-cleaning cycles are sequential, then updating the tag information associated with the heat exchange efficiency degradation rate again will be invalid. This ensures that the tag information for the heat exchange efficiency degradation rate is only valid when the air conditioner is in cooling or heating mode, thereby improving the compatibility between the target self-cleaning mode and the air conditioner's heat exchange performance.

[0078] Combination Figure 4 As shown, this disclosure provides another control method for an air conditioner, including:

[0079] S31, the air conditioner responds to a first control command used to trigger the execution of the self-cleaning mode and obtains tag information associated with the heat exchange efficiency decay rate of the indoor heat exchanger.

[0080] S32, if the label information indicates that the air conditioner is valid, obtain the heat exchange efficiency attenuation rate.

[0081] S33, the air conditioner determines and executes the target self-cleaning mode corresponding to the heat exchange efficiency decay rate based on the heat exchange efficiency decay rate.

[0082] S34, the air conditioner obtains the operating status of the target self-cleaning mode.

[0083] S35, when the air conditioner indicates that self-cleaning has ended, updating the label information associated with the heat exchange efficiency degradation rate is invalid.

[0084] S36, if the label information indicates that the air conditioner is invalid, a prompt message is sent to the user to ask whether to start the self-cleaning mode. The prompt message is used to indicate that the self-cleaning mode has been executed.

[0085] S37, the air conditioner responds to the feedback command sent by the user and executes the operating mode corresponding to the feedback command.

[0086] Using the control method for air conditioners provided in this embodiment, when the air conditioner determines that the tag information is invalid, it sends a prompt message to the user. Then, it determines whether to execute the self-cleaning mode based on the user's feedback instructions. In this way, the air conditioner can determine whether to continuously execute the self-cleaning mode based on the user's feedback instructions.

[0087] Optionally, the air conditioner responds to a feedback command sent by the user and executes an operating mode corresponding to the feedback command, including:

[0088] When the air conditioner receives a feedback command from the user, it executes the self-cleaning mode corresponding to the command.

[0089] The air conditioner will not enter self-cleaning mode if it does not receive a feedback command from the user.

[0090] In this way, the air conditioner can determine whether to continuously run the self-cleaning mode based on the user's needs.

[0091] Combination Figure 5 As shown, this disclosure provides another control method for an air conditioner, including:

[0092] S41, the air conditioner responds to the second control command used to trigger the execution of the target mode and executes the target mode.

[0093] S42, the air conditioner obtains the actual time taken for the current environmental information to be updated to the target environmental information when the air conditioner is running in the target mode.

[0094] In this step, the current environmental information includes the current temperature and / or humidity of the space where the air conditioner is located. The actual time it takes for the air conditioner to update from the current environmental information to the target environmental information when operating in target mode includes the actual time it takes for the air conditioner to update from the current environmental information to the target environmental information after it is turned on and operating in target mode. The air conditioner uses this actual time as a baseline time to calculate the heat exchange efficiency degradation rate.

[0095] It should be noted that the actual time taken for the air conditioner to update from the current environmental information to the target environmental information when running in target mode after being turned on includes: the time it takes for the air conditioner to acquire both the current and target environmental information after being turned on; the theoretical time taken for the air conditioner's location to update from the current environmental information to the target environmental information; and the storage of this theoretical time in the database. In this way, the air conditioner can obtain the aforementioned theoretical time by accessing the data stored in the database.

[0096] In addition, since the current environmental information of the space where the air conditioner is located changes in real time and the target environmental information is not static, the air conditioner can update the duration data stored in the database in real time based on the theoretical time it takes for the space to update from the current environmental information to the target environmental information after it is turned on.

[0097] S43, the air conditioner calculates the current heat exchange efficiency decay rate based on the actual duration and the theoretical duration.

[0098] S44, the air conditioner responds to a first control command used to trigger the execution of the self-cleaning mode and obtains tag information associated with the heat exchange efficiency decay rate of the indoor heat exchanger.

[0099] S45, if the label information indicates that the air conditioner is valid, obtain the heat exchange efficiency attenuation rate.

[0100] S46, the air conditioner determines and executes the target self-cleaning mode corresponding to the heat exchange efficiency decay rate based on the heat exchange efficiency decay rate.

[0101] The second control command includes target environmental information, and the target mode includes either cooling mode or heating mode.

[0102] By employing the control method for air conditioners provided in this disclosure, the air conditioner can obtain the actual duration and theoretical duration based on the acquired current environmental information and target environmental information. The heat exchange efficiency decay rate is then calculated based on the actual and theoretical durations, which helps improve the accuracy of the heat exchange efficiency decay rate calculation. This allows for an accurate assessment of the air conditioner's heat exchange performance.

[0103] Optionally, the air conditioner calculates the current heat exchange efficiency decay rate based on the actual duration and the theoretical duration, including:

[0104]

[0105] Among them, t 实际 t 理论 These represent the actual duration and the theoretical duration, respectively, and β represents the rate of decline in the initial heat exchange efficiency.

[0106] Thus, when the air conditioner operates in cooling or heating mode, the heat exchange efficiency decreases due to foreign matter adhering to the surface of the indoor heat exchanger. This means that in cooling or heating mode, the actual time required to update from the current environmental information to the target environmental information is increased. That is, t 实际 As the actual duration increases, the heat exchange efficiency decay rate also increases. Therefore, by obtaining the difference between the actual and theoretical durations, the air conditioner can accurately determine the heat exchange efficiency decay rate by comparing the difference with the theoretical duration. In practical applications, with a preset multiplier of 1.1, the heat exchange efficiency decay rate corresponding to the reference duration is β. 基准 :

[0107]

[0108] As shown in the formula above, if the theoretical duration is 10 minutes, then the baseline duration is 11 minutes. In this case, if the air conditioner's heat exchange efficiency decay rate is greater than or equal to the decay rate corresponding to the baseline duration of 11 minutes, it indicates that the heat exchange efficiency of the indoor heat exchanger is low, and the powerful self-cleaning mode is activated. Conversely, if the heat exchange efficiency decay rate is less than the decay rate corresponding to the baseline duration of 11 minutes, it indicates that although the heat exchange efficiency of the indoor heat exchanger has decreased, the blockage is not severe, and the normal self-cleaning mode is activated.

[0109] In another practical application, such as Figure 6 As shown, the control method for an air conditioner specifically performs the following steps:

[0110] S51, the air conditioner is turned on and running.

[0111] S52, the air conditioner determines whether it has received a second control command to trigger the execution of the cooling mode. If yes, execute S53; otherwise, execute S54.

[0112] S53, the air conditioner executes the target mode, and after obtaining the actual time and theoretical time for updating from the current environmental information to the target environmental information when running in cooling mode, it calculates the current heat exchange efficiency decay rate.

[0113] S54, the air conditioner determines whether it has received a first control command to trigger the execution of the self-cleaning mode. If so, proceed to S55.

[0114] S55: The air conditioner obtains the tag information and determines whether the tag information is valid. If valid, proceed to S56; otherwise, proceed to S59.

[0115] S56, the rate of decrease in heat exchange efficiency of the air conditioner.

[0116] S57, when the heat exchange efficiency attenuation rate is greater than or equal to the preset value, the air conditioner determines and executes the first self-cleaning mode.

[0117] S58, when the heat exchange efficiency decay rate is less than the preset value, the air conditioner determines and executes the second self-cleaning mode.

[0118] S59, the air conditioner sends a prompt message to the user to ask whether to activate the self-cleaning mode.

[0119] S60: The air conditioner responds to the feedback command sent by the user and executes the operating mode corresponding to the feedback command.

[0120] Combination Figure 7As shown, this embodiment of the disclosure provides a control device 200 for an air conditioner, including a response module 201, an acquisition module 202, and an execution module 203.
