[0047] The following describes some embodiments of the present invention with reference to the drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0048] Most of the newly launched air conditioners currently have the function of self-cleaning for both the indoor and outdoor units, and the self-cleaning generally works based on the principle of first frosting and then defrosting. This requires an environmental condition with a large temperature difference and relatively high humidity to perform self-cleaning more effectively.

[0049] The outdoor unit of the air conditioner is exposed to the outdoor environment. When the outdoor temperature is relatively high or the relative humidity is relatively low, the frosting condition becomes poor, which takes more time to complete self-cleaning and the air conditioner consumes more electrical energy. Therefore, randomly turning on or automatically turning on self-cleaning at a certain cycle will greatly increase energy consumption.

[0050] In view of this, the present invention provides a method for self-cleaning the outdoor unit of an air conditioner. When the air conditioner is in the standby state, obtain the time interval between the current date and the most recent historical self-cleaning date and obtain the current environmental parameters outdoors; at least determine whether the current environmental parameters meet the preset environmental parameter conditions, and compare the time interval with a preset time threshold; according to the determination result and the comparison result, control the air conditioner to perform self-cleaning. By controlling the air conditioner to perform self-cleaning by at least combining the current environmental parameters and the time interval from the most recent historical self-cleaning date, it is possible to avoid randomly turning on self-cleaning under non-suitable environmental conditions, which is beneficial to reducing energy consumption.

[0051] See Figure 1 as shown in Figure 1 FIG. is a schematic flowchart of a method for self-cleaning the outdoor unit of an air conditioner provided by an embodiment of the present invention, which may include:

[0052] Step S11: When the air conditioner is in the standby state, obtain the time interval between the current date and the most recent historical self-cleaning date and obtain the current environmental parameters outdoors;

[0053] Step S12: At least determine whether the current environmental parameters meet the preset environmental parameter conditions, and compare the time interval with a preset time threshold;

[0054] Step S13: According to the determination result and the comparison result, control the air conditioner to perform self-cleaning.

[0055] In some embodiments, step S11 may be specifically:

[0056] Obtain the current date and the most recent historical self-cleaning date;

[0057] Determine the time interval according to the current date and the most recent historical self-cleaning date.

[0058] In some embodiments, step S12 may be specifically: Determine whether the current environmental parameters meet the preset environmental parameter conditions, and compare the time interval with a preset time threshold.

[0059] Among them, the preset time threshold may include at least one of a pre-stored self-cleaning cycle, a first time threshold, and a second time threshold. The first time threshold is less than the second time threshold, and the second time threshold is less than the pre-stored self-cleaning cycle.

[0060] As an example, the first time threshold may be 5 days, and the second time threshold may be half of the self-cleaning cycle time.

[0061] In some other embodiments, the method may further include obtaining predicted environmental parameters within a preset number of days in the future. Step S12 may further include determining whether the current environmental parameters and the predicted environmental parameters meet the preset environmental parameter conditions, and comparing the time interval with the preset time threshold, so as to be able to perform self-cleaning under suitable environmental conditions and achieve the effect of energy conservation. For specific details, please refer to the description of another embodiment below.

[0062] In some embodiments, the environmental parameters may include environmental temperature and environmental humidity. In step S12, determining whether the current environmental parameters meet the preset environmental parameter conditions may specifically be:

[0063] Determining whether the environmental temperature is less than or equal to the preset environmental temperature threshold and whether the environmental humidity is greater than or equal to the preset environmental humidity threshold.

[0064] Among them, when the environmental temperature is less than or equal to the preset environmental temperature threshold and the environmental humidity is greater than or equal to the preset environmental humidity threshold, it is determined that the current environmental parameters meet the preset environmental parameter conditions. Turning on self-cleaning under the current environmental parameters is beneficial to energy conservation.

[0065] In some embodiments, step S13 may specifically be:

[0066] When the current environmental parameters do not meet the preset environmental parameter conditions, if the time interval is greater than or equal to the pre-stored self-cleaning cycle, a prompt to turn on self-cleaning and a self-cleaning energy consumption reminder may be sent to the user to determine whether to perform self-cleaning according to the user's feedback instruction; if the time interval is less than the pre-stored self-cleaning cycle, the air conditioner is controlled to remain in the standby state.

[0067] Or,

[0068] When the current environmental parameters meet the preset environmental parameter conditions, if the time interval is greater than or equal to the pre-stored self-cleaning cycle, the air conditioner may be controlled to turn on self-cleaning; if the time interval is less than the first time threshold, the air conditioner is controlled to remain in the standby state; if the time interval is greater than or equal to the first time threshold and less than the pre-stored self-cleaning cycle, a prompt to turn on self-cleaning may be sent to the user to prompt the user that the current environment is suitable for self-cleaning.

[0069] The above is a self - cleaning method for an air - conditioner outdoor unit provided by an embodiment of the present invention. When the air - conditioner is in the standby state, obtain the time interval between the current date and the most recent historical self - cleaning date and obtain the current environmental parameters outdoors; at least determine whether the current environmental parameters meet the preset environmental parameter conditions, and compare the time interval with a preset time threshold; control the air - conditioner to perform self - cleaning according to the determination result and the comparison result. By controlling the air - conditioner to perform self - cleaning by at least combining the current environmental parameters and the time interval from the most recent historical self - cleaning date, it is possible to avoid randomly starting self - cleaning and starting self - cleaning under non - suitable environmental conditions, which is beneficial to reducing energy consumption.

[0073] Step S23: Determine whether the current environmental parameters and the predicted environmental parameters meet the preset environmental parameter conditions, and compare the time interval with a preset time threshold;

[0074] Step S24: Control the air - conditioner to perform self - cleaning according to the determination result and the comparison result.

[0075] It should be noted that step S22 can be executed simultaneously with step S21, or step S21 can be executed first and then step S22, or step S22 can be executed first and then step S21.

[0076] In some embodiments, step S21 can be specifically:

[0077] Obtain the current date and the most recent historical self - cleaning date;

[0078] Determine the time interval according to the current date and the most recent historical self - cleaning date.

[0079] In some embodiments, step S22 can be specifically obtaining the weather information within a preset number of days in the future from the network as the predicted environmental parameters. Among them, the preset number of days can be set according to the requirements of the self - cleaning cycle. In some embodiments, different preset numbers of days can be set according to the current environmental parameters and / or the pre - stored self - cleaning cycle. The predicted environmental parameters can include predicted temperature and predicted humidity.

[0080] Among them, the preset time threshold may include at least one of a pre-stored self-cleaning cycle, a first time threshold, and a second time threshold. The first time threshold is less than the second time threshold, and the second time threshold is less than the pre-stored self-cleaning cycle.

[0081] In some embodiments, step S24 may be specifically:

[0082] When the determination result is that the current environmental parameters do not meet the preset environmental parameter conditions, the predicted environmental parameters meet the preset environmental parameter conditions, and the time interval is greater than or equal to the pre-stored self-cleaning cycle, control the air conditioner to delay self-cleaning;

[0083] When the determination result is that the current environmental parameters do not meet the preset environmental parameter conditions, the predicted environmental parameters do not meet the preset environmental parameter conditions, and the time interval is greater than or equal to the pre-stored self-cleaning cycle, send a prompt to start self-cleaning and a reminder of self-cleaning energy consumption;

[0084] When the determination result is that the current environmental parameters meet the preset environmental parameter conditions, the predicted environmental parameters meet the preset environmental parameter conditions, and the time interval is greater than or equal to the first time threshold and less than the second time threshold, control the air conditioner to delay self-cleaning;

[0085] When the determination result is that the current environmental parameters meet the preset environmental parameter conditions, the predicted environmental parameters do not meet the preset environmental parameter conditions, and the time interval is greater than or equal to the first time threshold and less than the second time threshold, send a prompt to start self-cleaning;

[0086] When the determination result is that the current environmental parameters do not meet the preset environmental parameter conditions and the time interval is less than the pre-stored self-cleaning cycle, control the air conditioner to remain in the standby state;

[0087] When the determination result is that the current environmental parameters meet the preset environmental parameter conditions and the time interval is less than the first time threshold, control the air conditioner to remain in the standby state;

[0088] When the determination result is that the current environmental parameters meet the preset environmental parameter conditions and the time interval is greater than or equal to the second time threshold and less than the pre-stored self-cleaning cycle, send a prompt to start self-cleaning;

[0089] When the determination result is that the current environmental parameters meet the preset environmental parameter conditions and the time interval is greater than or equal to the pre-stored self-cleaning cycle, control the air conditioner to start self-cleaning.

[0090] The above is a self - cleaning method for an air - conditioner outdoor unit provided by another embodiment of the present invention. When the air - conditioner is in the standby state, obtain the time interval between the current date and the most recent historical self - cleaning date and obtain the current environmental parameters outdoors; it is also possible to obtain the predicted environmental parameters within a preset number of days in the future; determine whether the current environmental parameters and the predicted environmental parameters meet the preset environmental parameter conditions, and compare the time interval with a preset time threshold; according to the determination result and the comparison result, control the air - conditioner to perform self - cleaning. By combining the current environmental parameters, the predicted environmental parameters within a preset number of days in the future, the time interval from the most recent historical self - cleaning date, and the preset time threshold, it is possible to flexibly recommend to the user the appropriate time to start self - cleaning, so as to be able to start self - cleaning under suitable environmental conditions, which is beneficial to reducing energy consumption.

[0091] In some other embodiments, in order to further save energy consumption, it is also possible to first determine whether the current environmental parameters and the predicted environmental parameters meet the preset environmental parameter conditions, and compare the time interval with the preset time threshold; then, according to the judgment result and the comparison result, obtain the predicted environmental parameters within a preset number of days in the future, and control the air - conditioner to perform self - cleaning in combination with the predicted environmental parameters within a preset number of days in the future. For specific details, please refer to the description below.

[0092] See Figure 3 as shown in Figure 3 is a schematic flowchart of a self - cleaning method for an air - conditioner outdoor unit provided by another embodiment of the present invention, which may include:

[0093] Step S31: When the air - conditioner is in the standby state, obtain the time interval between the current date and the most recent historical self - cleaning date and obtain the current environmental parameters outdoors;

[0094] Step S32: Determine whether the current environmental parameters meet the preset environmental parameter conditions, and compare the time interval with the preset time threshold;

[0095] When the determination result is that the current environmental parameters do not meet the preset environmental parameter conditions and the time interval is greater than or equal to the pre - stored self - cleaning cycle, execute steps S33 to S35; when the determination result is that the current environmental parameters do not meet the preset environmental parameter conditions and the time interval is less than the pre - stored self - cleaning cycle, control the air - conditioner to remain in the standby state.

[0096] Step S33: Obtain the predicted environmental parameters within the first preset number of days in the future;

[0097] Step S34: Determine whether the preset environmental parameters meet the preset environmental parameter conditions;

[0098] Step S35: When the predicted environmental parameters meet the preset environmental parameter conditions, control the air conditioner to postpone self-cleaning; when the predicted environmental parameters do not meet the preset environmental parameter conditions, send a prompt to start self-cleaning and a reminder of self-cleaning energy consumption.

[0099] Among them, the preset time thresholds include a first time threshold T1, a second time threshold T2, and a pre-stored self-cleaning cycle T. The first time threshold is less than the second time threshold, and the second time threshold is less than the pre-stored self-cleaning cycle. The time interval can be expressed as Δt.

[0100] When the determination result is that the current environmental parameters meet the preset environmental parameter conditions and the time interval is less than the first time threshold, control the air conditioner to remain in the standby state; when the determination result is that the current environmental parameters meet the preset environmental parameter conditions and the time interval is greater than or equal to the first time threshold and less than the second time threshold, execute steps S36 to S38; when the determination result is that the current environmental parameters meet the preset environmental parameter conditions and the time interval is greater than or equal to the second time threshold and less than the pre-stored self-cleaning cycle, send a prompt to start self-cleaning; when the determination result is that the current environmental parameters meet the preset environmental parameter conditions and the time interval is greater than or equal to the pre-stored self-cleaning cycle, control the air conditioner to start self-cleaning.

[0101] Step S36: Obtain the predicted environmental parameters within the next second preset number of days.

[0102] Step S37: Determine whether the preset environmental parameters meet the preset environmental parameter conditions.

[0103] Step S38: When the predicted environmental parameters meet the preset environmental parameter conditions, control the air conditioner to postpone self-cleaning; when the predicted environmental parameters do not meet the preset environmental parameter conditions, send a prompt to start self-cleaning.

[0104] Among them, steps S31 and S32 can be implemented in the same way as steps S11 and S12. For the sake of brevity, they will not be elaborated here. For specific details, please refer to the description above.

[0105] In some embodiments, step S33 and / or step S36 can specifically be to obtain the weather information within the next preset number of days from the network as the predicted environmental parameters. Among them, the preset number of days can be set according to the requirements of the self-cleaning cycle. As an example, the first preset number of days can be different from the second preset number of days. The first preset number of days can be set to be less than the number of days of the pre-stored self-cleaning cycle. As an example, the first preset number of days can be set to be equal to the first time threshold, and the second preset number of days can be set to be equal to the self-cleaning cycle, so as to be able to meet the suitable environmental parameter conditions and also be able to perform self-cleaning in a timely manner.

[0106] In some embodiments, the predicted environmental parameters may include the predicted environmental temperature and the predicted environmental humidity. Step S34 and / or step S37 may specifically be to determine whether the predicted environmental temperature is less than or equal to a preset environmental temperature threshold and whether the predicted environmental humidity is greater than or equal to a preset environmental humidity threshold.

[0107] In some embodiments, step S35 may specifically be to control the air conditioner to delay self-cleaning when the predicted environmental parameters meet the preset environmental parameter conditions; specifically, the actual time to start self-cleaning may be determined according to the date corresponding to the predicted environmental parameters; when the predicted environmental parameters do not meet the preset environmental parameter conditions, a prompt to start self-cleaning and a reminder of self-cleaning energy consumption are sent to determine whether to perform self-cleaning according to the user's feedback instruction.

[0108] In some embodiments, step S38 may specifically be to control the air conditioner to delay self-cleaning when the predicted environmental parameters meet the preset environmental parameter conditions; specifically, the actual time to start self-cleaning may be determined according to the date corresponding to the predicted environmental parameters; when the predicted environmental parameters do not meet the preset environmental parameter conditions, a prompt to start self-cleaning is sent to prompt the user that the current environmental parameters are suitable for starting self-cleaning, which can effectively save energy consumption.

[0109] The above is the air conditioner outdoor unit self-cleaning method provided by another embodiment of the present invention, which can achieve the beneficial effect of flexibly recommending to the user a suitable time to start self-cleaning by combining the current environmental parameters, the predicted environmental parameters within a preset number of future days, the time interval from the most recent historical self-cleaning date, and the preset time threshold, so as to be able to start self-cleaning under suitable environmental conditions, which is beneficial to reducing energy consumption. In addition, by first determining whether the current environmental parameters and the predicted environmental parameters meet the preset environmental parameter conditions, and comparing the time interval with the preset time threshold; then, according to the judgment results and the comparison results, obtaining the predicted environmental parameters within a preset number of future days, and controlling the air conditioner to perform self-cleaning in combination with the predicted environmental parameters within a preset number of future days, the beneficial effect of further saving energy consumption can be achieved.
