Description

Technical Field

[0001] The present application relates to the field of electrical equipment control technology, and in particular to a method and system for controlling power saving of electrical equipment. Background Art

[0002] With the development of technology, some electrical appliances have become popular in every household, such as common refrigerators and air conditioners. In hot or cold weather, users can turn on the air conditioner to quickly heat or cool the space they are in, so that the user feels more comfortable.

[0003] In the prior art, due to the high humidity in southern my country during the rainy season, clothes often cannot be dried out in the sun. Since some households do not have dryers, air conditioners often double as dryers. To dry clothes, users place the clothes in front of the air conditioner, which then switches to heating mode to dry the clothes.

[0004] Regarding the above-mentioned related technologies, the inventor believes that when the clothes are drying, if the air conditioner is in the sweeping mode, the clothes may not cover all the sweeping areas of the air conditioner, causing part of the air conditioner to operate ineffectively, thereby resulting in waste of electricity, and there is still room for improvement. Summary of the Invention

[0005] In order to reduce the waste of electricity caused by ineffective operation of air conditioners, the present application provides a power-saving control method and system for electrical equipment.

[0006] In a first aspect, the present application provides a method for controlling power saving of electrical equipment, which adopts the following technical solution:

[0007] A power saving control method for electrical equipment, comprising:

[0008] Get the air conditioning operation mode;

[0009] When the air conditioning operation mode is consistent with the preset sweeping and drying mode, the blades are controlled to swing within a preset lateral angle range and obtain obstacle distance information and detection angle information;

[0010] Calculate the obstacle distance information and the detection angle information to determine the direct distance information;

[0011] Determine the direct distance information with the smallest corresponding value according to a preset sorting rule, and define the distance value corresponding to the direct distance information as the base value distance;

[0012] Add the base distance to the preset empty synchronization set, and perform difference calculation based on the face distance information and the values ​​in the synchronization set to determine the deviation distance;

[0013] When the deviation distance under the same straight distance information is less than the preset closest distance, the straight distance information is added to the synchronization set;

[0014] Determine the detection angle information at the two extreme sides in the synchronization set according to the sorting rule, and define the angle value corresponding to the detection angle information as the boundary angle;

[0015] The drying operation range is determined according to the two boundary angles, and the blades are controlled to reciprocate within the drying operation range.

[0016] By adopting the above technical solution, the operating mode of the air conditioner is obtained. When the air conditioner needs to be used to dry clothes, the location of the clothes is determined by distance detection. At this time, the corresponding blowing and drying range is determined so that the blades swing back and forth only in the area where the clothes are, thereby reducing the situation where the air conditioner operates ineffectively, thereby reducing the waste of electricity from the air conditioner.

[0017] Optionally, the method further includes a step of controlling the blades to reciprocate within the drying operation range, the step comprising:

[0018] Within the drying operation range, the angle corresponding to the detection angle information corresponding to the direct distance information within the synchronization set is defined as a valid angle, and the remaining angles within the drying operation range are defined as invalid angles;

[0019] Determine the invalid road section based on the continuous invalid angles and perform calculations to determine the invalid road section range angle;

[0020] Determine whether the invalid road section range angle is greater than the preset jumpable angle;

[0021] If the invalid road section range angle is not greater than the jumpable angle, the invalid road section is defined as a normal road section;

[0022] If the invalid road section range angle is greater than the skip angle, the invalid road section is defined as a skip section;

[0023] The blades are controlled to swing at a preset first speed in the jumpable section, and are controlled to swing at a preset second speed in the remaining sections, wherein the first speed is greater than the second speed.

[0024] By adopting the above technical solution, when the blades swing to the gap position between the clothes, the swinging speed can be increased to reduce the blowing effect at this position, thereby further reducing the occurrence of ineffective operation of the air conditioner.

[0025] Optionally, after the skippable road section is determined, the power saving control method for the electric device further includes:

[0026] Calculate the distance between adjacent skippable sections to determine the skippable interval distance;

[0027] Determine whether the jumpable interval distance is less than a preset reference distance;

[0028] If the skippable interval is not less than the reference distance, the original skippable section will be maintained;

[0029] If the skippable interval distance is less than the reference distance, the section between the two skippable sections is defined as a skippable section.

[0030] By adopting the above technical solution, the situation in which clothes are swaying due to wind can be analyzed, so that the determined skippable road section is more accurate.

[0031] Optionally, during the reciprocating operation of the blades, the power-saving control method for the electrical equipment further includes:

[0032] When the blade swings to any boundary angle, calculation is performed based on the effective angle and invalid angle to determine the current effective ratio;

[0033] Calculate the difference between the current effective ratios obtained before and after to determine the deviation ratio value;

[0034] Determine whether the deviation ratio is greater than the preset upper limit of permission;

[0035] If the deviation ratio is not greater than the permitted upper limit, the blades will continue to operate reciprocatingly within the drying range.

[0036] If the deviation ratio is greater than the permitted upper limit, the blades are controlled to swing again within the lateral angle range to redefine the drying operation range.

[0037] By adopting the above technical solution, when the user changes the position of the clothes or stores some of the clothes, the drying operation range can be re-determined to make the drying operation more stable.

[0038] Optionally, in the process of controlling the blades to reciprocate within the drying operation range, the power-saving control method for the electrical equipment further includes:

[0039] Obtain information on work intensity and work duration;

[0040] Calculating based on the skippable road section and the first speed to determine a first duration, and calculating based on the remaining road sections that are not skippable road sections and the second speed to determine a second duration;

[0041] Performing a sum calculation based on the first duration and the second duration to determine single trip duration information;

[0042] Based on the single-trip duration information, the required duration information corresponding to the operation intensity information and the obstacle distance information is determined according to the preset duration matching relationship;

[0043] When the duration corresponding to the operation duration information reaches the duration corresponding to the required duration information, the valid angle is switched to the invalid angle.

[0044] By adopting the above technical solution, the air conditioner can be controlled to stop drying the clothes after they are dried, thereby further reducing energy waste.

[0045] Optionally, after the required duration information is determined, the power-saving control method for the electrical equipment further includes:

[0046] Determine whether the drying operation range includes the preset facing angle;

[0047] If the drying operation range does not include the facing angle, the effective angle is switched according to the determined required time information;

[0048] If the drying operation range includes the facing angle, the required duration information corresponding to the boundary angle is defined as the boundary duration information, and the boundary duration information with a smaller value is determined according to the sorting rule, and the duration corresponding to the boundary duration information is defined as the lower limit duration;

[0049] Calculate the difference between the lower limit duration and the required duration information to determine the compensation duration information;

[0050] Determining the corrected duration information corresponding to the compensated duration information according to a preset corrected matching relationship;

[0051] A difference calculation is performed based on the corrected duration information and the required duration information to update the required duration information.

[0052] By adopting the above technical solution, the drying time of clothes can be adjusted according to the time required for the blades to pass through part of the clothes when adjusting their positions, so that the clothes can be dried effectively while minimizing energy waste.

[0053] Optionally, also include:

[0054] Determine whether the current effective ratio is less than the preset lower limit ratio;

[0055] If the current effective ratio is not less than the lower limit ratio, the blade reciprocating operation is maintained;

[0056] If the current effective ratio is less than the lower limit ratio, the duration corresponding to the current operation duration information is defined as the switching duration, and the difference between the required duration information and the switching duration is calculated to determine the direct blowing duration;

[0057] Determine the fixed duration corresponding to the direct blowing duration, the operation intensity information, and the obstacle distance information according to the preset direct blowing matching relationship;

[0058] The blades are controlled to switch to a preset fixed direct blowing mode and operate in sequence with fixed time lengths from small to large according to the corresponding detection angle information.

[0059] By adopting the above technical solution, when only part of the clothes are not dried, there is no need for the blades to swing back and forth, so as to further reduce the occurrence of energy waste.

[0060] In a second aspect, the present application provides a power-saving control system for electrical equipment, which adopts the following technical solutions:

[0061] A power-saving control system for electrical equipment, comprising:

[0062] An acquisition module is used to obtain the air conditioning operation mode;

[0063] A processing module, connected to the acquisition module and the judgment module, for storing and processing information;

[0064] The judgment module is connected with the acquisition module and the processing module and is used for judging the information;

[0065] When the judgment module determines that the air conditioning operation mode is consistent with the preset sweeping and drying mode, the processing module controls the blades to swing within a preset lateral angle range and enables the acquisition module to obtain obstacle distance information and detection angle information;

[0066] The processing module calculates the obstacle distance information and the detection angle information to determine the direct distance information;

[0067] The processing module determines the direct distance information with the smallest corresponding value according to a preset sorting rule, and defines the distance value corresponding to the direct distance information as the base value distance;

[0068] The processing module adds the base value distance to a preset empty synchronization set, and performs difference calculation based on the direct distance information and each value in the synchronization set to determine the deviation distance;

[0069] When the judging module judges that the deviation distance under the same straight distance information is less than the preset closest distance, the processing module adds the straight distance information to the synchronization set;

[0070] The processing module determines the detection angle information at the two extreme sides in the synchronization set according to the sorting rule, and defines the angle value corresponding to the detection angle information as the boundary angle;

[0071] The processing module determines the drying operation range according to the two boundary angles, and controls the blades to reciprocate within the drying operation range.

[0072] By adopting the above technical solution, the acquisition module obtains the operating mode of the air conditioner. When the air conditioner needs to be used to dry clothes, the processing module determines the location of the clothes through distance detection, and then determines the corresponding blowing and drying range, so that the blades only swing back and forth in the area where there are clothes, so as to reduce the invalid operation of the air conditioner and thus reduce the waste of electricity of the air conditioner.

[0073] In summary, this application includes at least one of the following beneficial technical effects:

[0074] 1. When using air conditioning to dry clothes, the operating area of ​​the air conditioning blades can be determined according to the distribution of clothes, thereby reducing the occurrence of ineffective operation of the air conditioning and reducing the waste of electricity;

[0075] 2. The blades can be controlled to swing faster in the gaps between clothes to further reduce energy waste;

[0076] 3. The time required to dry clothes can be determined according to the wind strength and distance, thereby reducing the situation where the blades continue to process the already dried clothes, thereby further reducing the waste of electricity. BRIEF DESCRIPTION OF THE DRAWINGS

[0085] In order to make the purpose, technical solutions and advantages of this application more clear, the following Figure 1-8It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application.

[0086] The embodiments of the present application are described in further detail below with reference to the accompanying drawings.

[0087] An embodiment of the present application discloses a power-saving control method for electrical equipment. When a user needs to use an air conditioner to dry clothes, the blades are controlled to swing to know the distribution position of the clothes, so as to control the blades to swing only within the range where the clothes are located, so as to reduce the occurrence of ineffective operation of the air conditioner, thereby reducing the waste of air conditioning electricity; at the same time, when part of the clothes are dried, the clothes will not continue to be dried, so as to further reduce the waste of air conditioning electricity.

[0088] Reference Figure 1 The method flow of the power saving control method for electrical equipment includes the following steps:

[0089] Step S100: Acquire the air conditioning operation mode.

[0090] The air conditioning operation mode is the mode selected by the current user that the air conditioner needs to execute.

[0091] Step S101: When the air-conditioning operation mode is consistent with the preset sweeping and drying mode, the blades are controlled to swing within a preset lateral angle range and obstacle distance information and detection angle information are obtained.

[0092] The sweeping and drying mode is a mode set by the staff to use the air conditioner to dry clothes. When the air conditioner operation mode is consistent with the sweeping and drying mode, it means that the user needs to use the air conditioner to dry the clothes at this time; the blade is a blade that can swing horizontally in the air conditioner. The rotation axis of the blade is set vertically, and the horizontal angle range is the range in which the blade can swing. This angle range is compared to the horizontal angle, for example, 30°-150°. The distance value corresponding to the obstacle distance information is the distance value between the obstacles in the direction of the blade swinging, which can be obtained by installing a distance detection device on the blade. The angle value corresponding to the detection angle information is the angle value rotated when the blade obtains the corresponding obstacle distance information.

[0093] Step S102: performing calculations based on the obstacle distance information and the detection angle information to determine the direct distance information.

[0094] The distance value corresponding to the face distance information is the vertical distance value between the obstacle at the detection angle and the plane where the blade is located, which is determined by trigonometric calculation.

[0095] Step S103: determining the direct distance information with the smallest corresponding value according to a preset sorting rule, and defining the distance value corresponding to the direct distance information as the base distance.

[0096] Sorting rules are methods set by staff to sort the size of values, such as the bubble method. Through the sorting rules, the obstacle closest to the air conditioner can be found. The obstacle can basically be identified as clothing that needs to be dried. At this time, the base value distance is defined to distinguish different direct distances, thereby facilitating subsequent identification and analysis of other clothing.

[0097] Step S104: adding the base value distance to a preset empty synchronization set, and performing a difference calculation based on the face distance information and each value in the synchronization set to determine the deviation distance.

[0098] The synchronization set is an initially empty set for adding the face distance. The deviation distance is the difference between the determined face distance and the value in the synchronization set. In the initial case, the deviation distance is the difference between the face distance and the base value distance.

[0099] Step S105: When the deviation distance under the same straight distance information is less than the preset closest distance, the straight distance information is added to the synchronization set.

[0100] The closest distance is the maximum distance set by the staff when two face-to-face distances can be considered close. In other words, the obstacles corresponding to the two face-to-face distances should be the same. When the deviation distance is less than the closest distance under the same face distance information, it means that the face distance is close to at least one value in the synchronization set. At this time, it is highly likely that the obstacle corresponding to the face distance is clothing. At this time, it is added to the synchronization set to facilitate the determination of the remaining clothing.

[0101] Step S106 : Determine the detection angle information at the two extreme sides in the synchronization set according to the sorting rule, and define the angle value corresponding to the detection angle information as the boundary angle.

[0102] The detection angle information on the two sides is the angle value closest to the two boundary angles of the horizontal angle range in the synchronization set. The boundary angle is defined to distinguish different detection angles and facilitate subsequent analysis.

[0103] Step S107: Determine a drying operation range according to the two boundary angles, and control the blades to reciprocate within the drying operation range.

[0104] The drying operation range is the range between the two boundary angles, that is, the range where the clothes are present. At this time, controlling the blades to operate reciprocatingly within the drying operation range can effectively dry the clothes, thereby reducing the effect of the wind blown by the air conditioner on the area where the clothes are not present, thereby reducing the waste of electricity.

[0105] Reference Figure 2 , further comprising the step of controlling the blades to reciprocate within the drying operation range, the step comprising:

[0106] Step S200 : defining the angles corresponding to the detection angle information corresponding to the direct distance information in the synchronization set within the drying operation range as valid angles, and defining the remaining angles within the drying operation range as invalid angles.

[0107] Valid angles and invalid angles are defined to distinguish between angles within the drying operation range at which clothes can be dried and angles at which clothes cannot be dried, which facilitates further analysis.

[0108] Step S201: determining an invalid road section based on continuous invalid angles and performing calculations to determine the range angle of the invalid road section.

[0109] An invalid section is an angular section that starts from an invalid angle and extends in any direction until it encounters a valid angle. The invalid section range angle is the angle of the determined invalid section. For example, if the determined invalid section is 60°-5°, the invalid section range angle is 5°.

[0110] Step S202: Determine whether the invalid road section range angle is greater than a preset jumpable angle.

[0111] The jumpable angle is the minimum range angle set by the staff to determine that there is a large gap between the clothes. The purpose of the judgment is to know whether the invalid section determined at this time is large in range.

[0112] Step S2021: If the invalid road section range angle is not greater than the jumpable angle, the invalid road section is defined as a normal road section.

[0113] When the invalid section range angle is not greater than the jumpable angle, it indicates that the gap between the two pieces of clothing is normal. At this time, the invalid section is defined as a normal section for identification, so as to distinguish different invalid sections and facilitate subsequent analysis.

[0114] Step S2022: If the range angle of the invalid road section is greater than the skippable angle, the invalid road section is defined as a skippable road section.

[0115] When the invalid section range angle is greater than the jumpable angle, it means that the gap between the two clothes is large. If the wind blown by the blades acts in this direction, invalid operation will occur. At this time, the invalid section is defined as a jumpable section for identification, so as to distinguish different invalid sections and facilitate subsequent analysis.

[0116] Step S203: controlling the blades to swing at a preset first speed on the skippable section, and controlling the blades to swing at a preset second speed on the remaining sections, wherein the first speed is greater than the second speed.

[0117] The blades are controlled to swing at the skippable section at the first speed so that the blades can quickly skip over the position that does not require drying treatment, thereby reducing the length of invalid operation. The first speed and the second speed are both input in advance by the staff and will not be described here.

[0118] Reference Figure 3 After the skippable road section is determined, the power saving control method for the electric device further includes:

[0119] Step S300: performing distance calculation based on adjacent skippable road sections to determine a skippable interval distance.

[0120] The skippable interval distance is the distance value between the determined skippable sections.

[0121] Step S301: Determine whether the jumpable interval distance is less than a preset reference distance.

[0122] The reference distance is the minimum skippable interval distance set by the staff when there are clothes that need to be dried between the skippable sections. The purpose of the judgment is to find out whether the remaining sections between the skippable sections are misdetected due to the swinging of clothes.

[0123] Step S3011: If the skippable interval distance is not less than the reference distance, the original skippable road section is maintained.

[0124] When the jumpable interval distance is not less than the reference distance, it means that there is indeed corresponding clothing between the two jumpable sections. At this time, the original jumpable section can be maintained.

[0125] Step S3012: If the skippable interval distance is less than the reference distance, the section between the two skippable sections is defined as a skippable section.

[0126] When the skippable interval distance is less than the reference distance, it means that the section between the skippable sections determined at this time cannot meet the requirement of the presence of clothing. At this time, it is defined as a skippable section to make the subsequent blade operation more stable and accurate.

[0127] Reference Figure 4 During the reciprocating operation of the blades, the power-saving control method for the electrical equipment further includes:

[0128] Step S400 : When the blade swings to any boundary angle, calculation is performed according to the effective angle and the invalid angle to determine the current effective ratio.

[0129] The current effective proportion is the proportion of the effective angle determined when the blade moves from one boundary angle to another boundary angle to the drying angle range.

[0130] Step S401: performing a difference calculation based on the current effective proportions obtained before and after to determine a deviation proportion value.

[0131] The deviation ratio value is the difference between the current effective ratios obtained before and after the adjacent ones, and the difference is an absolute value.

[0132] Step S402: Determine whether the deviation ratio is greater than a preset upper limit.

[0133] The permissible upper limit is the minimum deviation percentage value set by the staff to determine that the position of the clothes that need to be dried has changed significantly. The purpose of the judgment is to know whether the clothes have changed significantly.

[0134] Step S4021: If the deviation ratio is not greater than the permitted upper limit, the blades continue to reciprocate within the drying operation range.

[0135] When the deviation ratio is not greater than the upper limit of the allowable value, it means that there is no significant position change in the clothes, and normal operation can be maintained.

[0136] Step S4022: If the deviation ratio is greater than the upper limit allowed, the blades are controlled to swing again within the lateral angle range to redefine the drying operation range.

[0137] When the deviation ratio is greater than the allowed upper limit, it means that the position of the clothes has changed significantly. At this time, the user may take away the dried clothes and adjust the remaining clothes. At this time, the control blades are re-swung within the lateral angle range to determine a more accurate drying operation range, so that the air conditioner can operate more stably when in the sweeping drying mode.

[0138] Reference Figure 5 In the process of controlling the blades to reciprocate within the drying operation range, the power-saving control method for the electrical equipment further includes:

[0139] Step S500: Obtaining operation intensity information and operation duration information.

[0140] The intensity value corresponding to the operation intensity information is the wind intensity value for drying and blowing set by the current user, and the duration value corresponding to the operation duration information is the duration value of the reciprocating operation of the blade. It can be obtained from zero timing when the drying operation range is determined and the blade operation is controlled.

[0141] Step S501: Calculate a first duration based on the skippable road section and the first speed, and calculate a second duration based on the remaining road sections that are not skippable road sections and the second speed.

[0142] The first duration is the time required for the blade to pass through all skippable sections during the swinging process, which is determined by dividing the length of the skippable section by the first speed. The second duration is the time required for the blade to pass through all remaining sections that are not skippable sections during the swinging process, which is determined by dividing the length of the remaining sections by the second speed.

[0143] Step S502: performing a sum calculation based on the first duration and the second duration to determine single-trip duration information.

[0144] The duration value corresponding to the single-trip duration information is the total duration value required for the blade to swing from one boundary angle to another boundary angle, which is determined by adding the first duration to the second duration.

[0145] Step S503: Determine the required duration information corresponding to the operation intensity information and the obstacle distance information according to a preset duration matching relationship under the single trip duration information.

[0146] The duration value corresponding to the required duration information is the duration value required to completely dry the clothes. Different single-trip duration information indicates different drying frequencies of clothes in the same time. Different work intensity information and obstacle distance information indicate different drying effects of clothes in the same time. Therefore, the duration matching relationship between the four is determined in advance by the staff based on multiple tests.

[0147] Step S504: When the duration corresponding to the operation duration information reaches the duration corresponding to the required duration information, the valid angle is switched to the invalid angle.

[0148] When the time corresponding to the operation duration information reaches the time corresponding to the required duration information, it means that the clothes at this position have been successfully dried. At this time, the effective angle is switched to an invalid angle so that there is no need to continue drying this position in the future, thereby improving efficiency and minimizing energy waste.

[0149] Reference Figure 6 After the demand duration information is determined, the power saving control method for the electrical equipment further includes:

[0150] Step S600: determining whether the drying operation range includes a preset facing angle.

[0151] The facing angle is the angle at which the wind energy blown out by the blades acts on the front of the air conditioner. In this application, the facing angle is 90°. The purpose of the judgment is to know whether the blades should dry the position at the facing angle while drying the rest of the clothes.

[0152] Step S6001: If the drying operation range does not include the facing angle, the effective angle is switched according to the determined required time information.

[0153] When the drying operation range does not include the facing angle, it means that the clothes to be dried are all on one side. At this time, the drying time gradually increases towards the side away from the center, that is, the clothes closest to the facing angle are dried first, and then the drying process can be carried out normally.

[0154] Step S6002: If the drying operation range includes the facing angle, the required duration information corresponding to the boundary angle is defined as the boundary duration information, and the boundary duration information with a smaller corresponding value is determined according to the sorting rules, and the duration corresponding to the boundary duration information is defined as the lower limit duration.

[0155] When the drying operation range includes a facing angle, it means that the clothes are on both sides. That is, when the air conditioner is drying the clothes on both sides, it will definitely process the clothes in the middle. At this time, the required time of the middle clothes can be appropriately shortened so that the clothes can be dried through the subsequent processing of other clothes. That is, the middle clothes are dried to a degree close to completion, and then part of the wind energy output during the swinging of the blades is used to completely dry the clothes; define boundary time information to distinguish different required time information, and at the same time define a lower limit time for subsequent analysis.

[0156] Step S601: performing a difference calculation based on the lower limit duration and the required duration information to determine the compensation duration information.

[0157] The duration value corresponding to the compensation duration information is the duration during which the undried clothes can be dried by utilizing the swinging blades, and is determined by subtracting the duration value corresponding to the required duration information from the lower limit duration.

[0158] Step S602: determining the corrected duration information corresponding to the compensated duration information according to the preset corrected matching relationship.

[0159] The time value corresponding to the corrected time information is the time value that can be used to correct the drying time of the clothes. Different compensation time values ​​indicate that the time when the clothes can be dried later is different, so the corrected time information is also different. The correction matching relationship between the two is determined in advance by the staff based on multiple tests and will not be elaborated on.

[0160] Step S603: performing a difference calculation based on the corrected duration information and the required duration information to update the required duration information.

[0161] The time corresponding to the required time information is subtracted from the time corresponding to the corrected time information to determine the actual required time for the clothes. At this time, when the drying time of the clothes reaches the required time, the effective angle is switched to the invalid angle. At this time, the clothes are not completely dried, but the blades will pass through the clothes at the first speed when swinging, and part of the wind force will act on the clothes to dry the clothes, thereby effectively utilizing the air volume to further reduce energy waste.

[0162] Reference Figure 7 , the power-saving control method for electrical equipment further includes:

[0163] Step S700: Determine whether the current effective ratio is less than a preset lower limit ratio.

[0164] The lower limit ratio is the maximum current effective ratio set by the staff when the amount of undried clothes is small. The purpose of the judgment is to know whether the current amount of undried clothes is small.

[0165] Step S7001: If the current effective ratio is not less than the lower limit ratio, the blade reciprocating operation is maintained.

[0166] When the current effective proportion is not less than the lower limit proportion, it means that there are still many clothes that have not been dried, and the drying operation can be carried out normally.

[0167] Step S7002: If the current effective proportion is less than the lower limit proportion, the duration corresponding to the current operation duration information is defined as the switching duration, and the difference calculation is performed based on the required duration information and the switching duration to determine the direct blowing duration.

[0168] When the current effective ratio is less than the lower limit ratio, it means that the amount of undried clothes is already small. If the sweeping mode is still used at this time, many invalid operations will occur, which requires further analysis; define the switching duration to mark the time the current clothes are dried, and the direct blowing duration is the duration value that needs to be processed under the original swinging operation to meet the clothes drying requirements. It is determined by subtracting the switching duration from the duration value corresponding to the required duration information.

[0169] Step S701: determining a fixed duration corresponding to the direct blowing duration, the work intensity information, and the obstacle distance information according to a preset direct blowing matching relationship.

[0170] The fixed time is the time required to directly dry the clothes that have switched the drying time so that the clothes meet the drying requirements. Different direct blowing times, work intensity information and obstacle distance information will lead to inconsistent fixed times. Therefore, the direct blowing matching relationship between the four is determined in advance by the staff based on multiple tests.

[0171] Step S702: Control the blades to switch to a preset fixed direct blowing mode, and operate in sequence with fixed time lengths from small to large according to the corresponding detection angle information.

[0172] The fixed direct blowing mode is a mode in which the blades do not swing to output wind in a fixed direction. From small to large means that the clothes with smaller fixed time are processed first, and then the clothes with the largest fixed time are processed in turn. For example, the fixed time determined when switching the time includes 1min, 2min and 3min. At this time, the blade blowing operation is first performed according to the detection angle of the clothes corresponding to 1min, so that the clothes can be dried first, and then the clothes corresponding to 2min and 3min are processed in turn.

[0176] The judgment module is connected with the acquisition module and the processing module and is used for judging the information;

[0177] When the judgment module determines that the air conditioning operation mode is consistent with the preset sweeping and drying mode, the processing module controls the blades to swing within a preset lateral angle range and enables the acquisition module to obtain obstacle distance information and detection angle information;

[0178] The processing module calculates the obstacle distance information and the detection angle information to determine the direct distance information;

[0179] The processing module determines the direct distance information with the smallest corresponding value according to a preset sorting rule, and defines the distance value corresponding to the direct distance information as the base value distance;

[0180] The processing module adds the base value distance to a preset empty synchronization set, and performs difference calculation based on the direct distance information and each value in the synchronization set to determine the deviation distance;

[0181] When the judging module judges that the deviation distance under the same straight distance information is less than the preset closest distance, the processing module adds the straight distance information to the synchronization set;

[0182] The processing module determines the detection angle information at the two extreme sides in the synchronization set according to the sorting rule, and defines the angle value corresponding to the detection angle information as the boundary angle;

[0183] The processing module determines the drying operation range according to the two boundary angles and controls the blades to reciprocate within the drying operation range;

[0184] The reciprocating operation control module is used to control the reciprocating movement of the blades within the drying operation range, so that the blades can move faster when they move between the gaps between the clothes, thereby improving the drying efficiency and reducing energy waste;

[0185] The skippable road section review module is used to determine the more accurate skippable road sections;

[0186] The clothing movement determination module is used to determine whether there is a large-scale movement of clothing, so that the user can re-determine the corresponding drying operation range after storing some clothing;

[0187] The clothes drying control module determines the clothes drying time according to the wind strength, thereby reducing the situation where dried clothes are continuously processed;

[0188] The demand duration correction module determines the more accurate demand duration based on the distribution of clothing;

[0189] The mode switching control module controls the blades to not swing back and forth when only some clothes are not dried, thereby further reducing energy waste.
