Description

Technical Field

[0001] The present invention belongs to the technical field of household appliance control, and specifically relates to a weighing correction system and a weighing correction method for a dryer. Background Art

[0002] Dryers have become increasingly important in modern households, especially in the southern regions with wet and cold winters, as well as during the period of returning dampness and the plum rain season. They are essential appliances. Quick drying, that is, drying clothes immediately after washing, eliminates the need to wait for sunny days to do laundry, bringing great convenience to people. However, due to differences in platforms, structures, and configurations, dryers cannot share a set of weighing parameters. Inaccurate weighing can lead to uncontrollable drying times, and parameter calibration needs to be carried out for each model configuration.

[0003] Currently, the structures and configurations of different models can affect the humidity values detected by the metal strips and the humidity differences between two adjacent measurements. For example, whether the whole machine configuration has an independent blower. With an independent blower, the air volume is large, which easily blows small loads to the front of the drum, causing the average humidity detected by the metal strip to increase and the humidity difference between two adjacent measurements to decrease, resulting in an overestimation of the calculated weighing level. The positions of the metal strips are different. The metal strips with 3D dryness determination function are installed on the side, while those without 3D dryness determination function are installed directly below the door. Different installation positions result in different contact areas with wet clothes, leading to different detected average humidity and humidity differences. In addition, the thickness dimensions of the drum, such as the different front and rear spaces inside the drum for ultra-thin platforms and thick platforms. For ultra-thin platforms, wet clothes are more likely to come into contact with the metal strips. Such factors will cause the calibration parameter average humidity values and humidity differences set in the program to be not universal.

[0004] In view of this, the present invention is specifically proposed. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a weighing correction system and a weighing correction method for a dryer. By moving the weighing detection stage to the beginning of the heating stage, that is, when the motor is always rotating forward, a stable state is achieved when detecting humidity values. And after the weighing is completed in the early stage of heating, the weighing-related data is automatically stored in the database for easy program reading and judgment, and the detected humidity average value and the humidity difference are sequentially judged and adjusted to achieve the purpose of accurate weighing, low cost, and applicability to dryers with various configurations.

[0006] To solve the above technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0007] The present invention provides a weighing correction system for a dryer, including:

[0008] A dryer module that runs drying programs corresponding to different actual load levels;

[0009] A storage module that stores a number of average humidity thresholds, a number of humidity difference thresholds, and the gear values corresponding to the thresholds;

[0010] A humidity detection module for detecting the humidity value of the loaded clothes during the operation of the clothes drying program;

[0011] A control module that calculates the average humidity value and the humidity difference based on the detected humidity value, compares them with the stored average humidity threshold and humidity difference threshold, determines the weighing level of the loaded clothes in combination with the gear value corresponding to the threshold, compares it with the actual load level, and judges whether to correct the average humidity threshold and / or humidity difference threshold;

[0012] An operation interface for selecting the corresponding program when performing calibration operations on parameters.

[0013] Further, the clothes dryer module runs the clothes drying program corresponding to each actual load level n times at a determined load weight; the gear value is divided according to the load weight intervals composed of different weight critical values. When the control module calculates the weighing level, it adds the gear value corresponding to the average humidity value and the gear value corresponding to the humidity difference, takes the average value and then rounds it to calculate the weighing level.

[0014] Further, when performing the inspection, first select the actual load level to be calibrated on the operation interface as the reference value for comparison, then determine the gear values corresponding to the average humidity value and humidity difference obtained by calculation according to the gear values corresponding to the average humidity threshold and humidity difference threshold recorded in the storage module, calculate the weighing level according to the gear value corresponding to the average humidity value and the gear value corresponding to the humidity difference, compare the calculated weighing level with the actual load level, and then judge whether to correct the average humidity value threshold and humidity difference threshold.

[0015] Further, the control module calculates the corresponding average humidity value and humidity difference based on the humidity values of the same weight recorded multiple times by the humidity detection module, calculates the weighing level, compares the multiple calculated weighing levels with the actual load level corresponding to this weight. If the data where the actually calculated weighing level is equal to the actual load level corresponding to this weight is less than the preset ratio, then it is necessary to correct the stored average humidity threshold and humidity difference threshold.

[0016] Further, when the control module judges that it is necessary to correct the average humidity threshold and humidity difference threshold corresponding to the actual load level at a certain weight, if the number of gear values corresponding to the average humidity values recorded multiple times that are equal to the actual load level value at this weight is less than the preset ratio, then correct the stored average humidity threshold, and re-statistics the data of the calculated weighing level after correction;

[0017] If the number of gear values corresponding to the average humidity values recorded multiple times that are equal to the actual load level value at this weight is greater than or equal to the preset ratio, there is no need to adjust the stored average humidity threshold, and directly correct the stored humidity difference threshold, and then statistically calculate the data of the weighing level again after correction.

[0018] Further, after correcting the average humidity threshold, if it is determined that the data ratio of multiple weighing levels calculated again after correction that are equal to the actual load level corresponding to this weight is still less than the preset ratio, then judge the relationship between the number of gear values corresponding to the humidity differences recorded multiple times that are equal to the actual load level value at this weight and the preset ratio. If the number of gear values corresponding to the humidity differences recorded multiple times that are equal to the actual load level value at this weight is less than the preset ratio, then correct the stored humidity difference threshold, and statistically calculate the data of the weighing level again after correction;

[0019] If the number of gear values corresponding to the humidity differences recorded multiple times that are equal to the actual load level value at this weight is greater than or equal to the preset ratio, then continue to return and correct the average humidity value threshold, and statistically calculate the data of the weighing level again after correction.

[0020] Further, when the average humidity threshold needs to be corrected, if the gear values corresponding to multiple average humidity values that are not equal to the actual load level are less than the actual load level corresponding to this weight, then reduce the average humidity value threshold corresponding to this small gear value by a preset amplitude; if the gear values corresponding to multiple average humidity values that are not equal to the actual load level are greater than the actual load level corresponding to this weight, then increase the average humidity value threshold corresponding to this actual load level by a preset amplitude;

[0021] When the humidity difference threshold needs to be corrected, if the gear values corresponding to multiple humidity differences that are not equal to the actual load level are less than the actual load level corresponding to this weight, then increase the humidity difference threshold corresponding to this small gear value by a preset amplitude; if the gear values corresponding to multiple humidity differences that are not equal to the actual load level are greater than the actual load level corresponding to this weight, then reduce the humidity difference threshold corresponding to this actual load level by a preset amplitude.

[0022] The present invention also provides a weighing correction method for a dryer, and the weighing correction method for the dryer corrects the weighing parameters of the dryer by using a weighing correction system for a dryer as described above.

[0023] Further, it includes the following steps:

[0024] S1. During the heating stage, the humidity detection module detects the humidity of the loaded clothes to obtain a humidity value;

[0025] S2. The control module calculates the humidity difference and the average humidity value based on the humidity value, calculates the weighing level by using the average humidity value and the gear value corresponding to the humidity difference obtained from the calculation, compares the obtained weighing level with the actual load level, and determines the correct value ratio of the weighing level data calculated in multiple groups that conforms to the actual load level.

[0026] S3. After the judgment, it is determined whether to adjust the average humidity threshold and the humidity difference threshold according to the judgment result. If adjustment is required, the adjusted average humidity value threshold and humidity difference threshold are automatically written into the program.

[0027] The present invention also provides a dryer, and the dryer applies a weighing correction method for a dryer as described above.

[0028] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art:

[0029] 1. By determining the accuracy rate of the actual weighing level during the correction process and adjusting the stored average humidity threshold and humidity difference threshold when the accuracy rate does not meet the preset ratio, the weighing detection of the adjusted model is made more accurate.

[0030] 2. By adjusting the stored average humidity threshold and humidity difference threshold through multiple-step adjustment and automatically determining the adjustment direction of the average humidity threshold and humidity difference threshold, the weighing method of different models can be adjusted step by step more precisely, and the data can be corrected more accurately.

[0042] Embodiment 1

[0043] This embodiment provides a dryer weighing calibration system, including: a dryer module that runs drying programs corresponding to different actual load levels; a storage module that stores a number of average humidity thresholds, a number of humidity difference thresholds, and the gear values corresponding to the thresholds; a humidity detection module that is used to detect the humidity value of the loaded clothes during the operation of the drying program; a control module that calculates the average humidity value and the humidity difference based on the detected humidity value, compares them with the stored average humidity threshold and humidity difference threshold, determines the weighing level of the loaded clothes in combination with the gear value corresponding to the threshold, compares it with the actual load level, and judges whether to correct the average humidity threshold and / or the humidity difference threshold; an operation interface that is used to select the corresponding program when performing parameter calibration operations.

[0044] Specifically, the humidity detection module performs feedback operations on the humidity values detected by the metal strip during the detection period to generate an average humidity value and a humidity difference value. The dryer is also divided into a thick platform and a thin platform according to the depth of the drum. The two groups of data of 1-16 kg and the weighing parameter correction table of the thick platform and the thin platform are stored in the storage module, and the actual data and parameter weighing correction table to be applied are selected according to the platform configuration. The storage module stores the preset standard average humidity threshold and humidity difference threshold, and stores multiple groups of average humidity values and humidity difference values actually detected during the calibration process, so as to facilitate the operation of these detected data and the stored data in the control module after detecting the preset number of average humidity values and humidity difference values. After the operation is completed, the obtained weighing level is compared with the actual load level selected on the operation interface, and it is judged whether the ratio meets the preset ratio.

[0045] The dryer module runs the drying program corresponding to each actual load level n times with a certain load weight; the gear values are divided according to the load weight intervals composed of different weight critical values. When the control module calculates the weighing level, the gear value corresponding to the average humidity value and the gear value corresponding to the humidity difference value are added, averaged, and then rounded to calculate the weighing level.

[0046] Specifically, as Figure 1 , 2 shown, the load weight critical values are set for dividing gears, such as 1 kg, 3 kg, 7 kg. The load weight critical values form load weight intervals, and each interval corresponds to a load gear. When the load weight is less than 1 kg, it corresponds to load gear 0. When the load weight interval is 1-3 kg, it corresponds to load gear 1. When the load weight interval is 3-7 kg, it corresponds to load gear 2. When the load weight is greater than 7 kg, it corresponds to load gear 3, so as to divide the load gears. And these load gears respectively correspond to an average humidity threshold and a humidity difference threshold. When calculating the weighing level of the entire detection process, the gear value corresponding to the calculated average humidity value and the gear value corresponding to the humidity difference value are added, averaged, and then rounded to calculate the final weighing level for comparison with the actual load level.

[0047] During the inspection, first select the actual load level to be calibrated on the operation interface as the reference value for comparison, then determine the gear values corresponding to the average humidity value and humidity difference value obtained by calculation according to the gear values corresponding to the average humidity threshold and humidity difference threshold recorded in the storage module. Calculate the weighing level according to the gear value corresponding to the average humidity value and the gear value corresponding to the humidity difference value. After comparing the calculated weighing level with the actual load level, it is then judged whether to correct the average humidity value threshold and the humidity difference threshold.

[0048] Specifically, the actual load level is the reference value for calibration set in the backdoor mode of the weighing calibration during the debugging program. The weighing calibration backdoor is a special mode for weighing calibration entered through a specific combination of keys on the operation interface. When calibrating the parameters of the dryer before leaving the factory, first select the actual load level as the standard, and then compare the calculated weighing level with the actual load level in the control module to determine whether to calibrate the stored threshold value.

[0049] The control module calculates the corresponding average humidity value and humidity difference value based on the humidity values recorded multiple times by the humidity detection module at the same weight, calculates the weighing level, and compares the multiple calculated weighing levels with the actual load level corresponding to this weight. If the data of the actually calculated weighing level equal to the actual load level corresponding to this weight is less than the preset ratio, then the stored average humidity threshold value and humidity difference threshold value need to be corrected.

[0050] Specifically, when it is necessary to calibrate the parameters stored corresponding to a certain weight, first select the actual load gear to be calibrated in the administrator mode of the operation interface, then put the clothes with the specified weight parameters into the dryer to run the detection program, and repeat it multiple times. In the control module, calculate the actual average humidity value and humidity difference value detected multiple times, compare the obtained weighing level with the pre-selected actual load level. If the correct rate of comparing these multiple actually detected and calculated weighing levels with the actual load level is less than the preset ratio, it means that the stored average humidity threshold value and humidity difference threshold value constituting the actual load level do not match the actually detected data, and the stored data needs to be corrected.

[0051] When the control module determines that it is necessary to correct the average humidity threshold value and humidity difference threshold value corresponding to the actual load level at a certain weight, if the number of gear values corresponding to the average humidity values recorded multiple times equal to the actual load level value at this weight is less than the preset ratio, then correct the stored average humidity threshold value, and then statistically calculate the data of the weighing level again;

[0052] If the number of gear values corresponding to the average humidity values recorded multiple times equal to the actual load level value at this weight is greater than or equal to the preset ratio, there is no need to adjust the stored average humidity threshold value, directly correct the stored humidity difference threshold value, and then statistically calculate the data of the weighing level again.

[0053] Specifically, after selecting the actual load level to be calibrated on the operation interface, if the control module determines that the ratio of the calculated weighing level to the actual load level is less than the preset ratio, it is necessary to calibrate the average humidity threshold and humidity difference threshold corresponding to this actual load level stored. First, judge the ratio of the gear value corresponding to the recorded average humidity value to the actual load level. If it is less than the preset ratio, correct the average humidity threshold stored corresponding to this gear. After the correction is completed, calculate the weighing level again.

[0054] If the ratio of the calculated average humidity value to the actual load level is greater than or equal to the preset ratio, it means that the stored average humidity threshold conforms to the actual situation of the current dryer. And because the ratio of the calculated weighing level to the actual load level is less than the preset ratio, it means that the stored humidity difference threshold needs to be corrected. After the correction, count the calculated weighing level again until the ratio of the obtained weighing level to the actual load level reaches the preset ratio and stop the correction, and automatically write the finally obtained weighing correction parameters into the program.

[0055] After correcting the average humidity threshold, if it is determined that the ratio of the data of multiple calculated weighing levels equal to the actual load level corresponding to this weight is still less than the preset ratio after the correction, then judge the relationship between the number of gear values corresponding to the multiple recorded humidity differences equal to the actual load level value at this weight and the preset ratio. If the number of gear values corresponding to the multiple recorded humidity differences equal to the actual load level value at this weight is less than the preset ratio, correct the stored humidity difference threshold, and count the data of the calculated weighing level again after the correction;

[0056] If the number of gear values corresponding to the multiple recorded humidity differences equal to the actual load level value at this weight is greater than or equal to the preset ratio, continue to return to correct the average humidity value threshold, and count the data of the calculated weighing level again after the correction.

[0057] Specifically, if the average humidity threshold needs to be corrected, after the correction, if the proportion of the calculated weighing level still does not reach the preset proportion, it is further determined whether the gear value corresponding to the recorded humidity difference is equal to the proportion of the actual load level. If the gear value corresponding to the recorded humidity difference is equal to the proportion of the actual load level and is less than the preset proportion, the stored humidity difference threshold needs to be corrected, and after the correction, the weighing level is statistically calculated again. If the gear value corresponding to the recorded humidity difference is equal to the proportion of the actual load level and is greater than or equal to the preset proportion, it indicates that the humidity difference threshold conforms to the data of the current dryer and does not need to be corrected. At this time, the average humidity threshold needs to be adjusted again, and after the correction, the statistically calculated weighing level is used until the proportion of the obtained weighing level equal to the actual load level reaches the preset proportion, and then the finally obtained weighing correction parameter is automatically written into the program.

[0058] When the average humidity threshold needs to be corrected, if the gear values corresponding to multiple average humidity values that are not equal to the actual load level are less than the actual load level corresponding to this weight, the average humidity value threshold corresponding to this small gear value is reduced by a preset amplitude; if the gear values corresponding to multiple average humidity values that are not equal to the actual load level are greater than the actual load level corresponding to this weight, the average humidity value threshold corresponding to this actual load level is increased by a preset amplitude.

[0059] When the humidity difference threshold needs to be corrected, if the gear values corresponding to multiple humidity differences that are not equal to the actual load level are less than the actual load level corresponding to this weight, the humidity difference threshold corresponding to this small gear value is increased by a preset amplitude; if the gear values corresponding to multiple humidity differences that are not equal to the actual load level are greater than the actual load level corresponding to this weight, the humidity difference threshold corresponding to this actual load level is reduced by a preset amplitude.

[0060] Specifically, as Figures 3 - 5 shown, when correcting the average humidity threshold, it is necessary to determine the direction in which the threshold needs to be adjusted and which threshold to adjust. The algorithm for calculating the weighing level is as follows: when it is greater than the humidity difference gear, the corresponding gear is taken; when it is less than the average humidity value gear, the corresponding gear is taken. As Figure 3 shown, the calculated weighing level in the dryer should be 3, but actually 2 accounts for 70% of the total data of this weight, then it is determined that an automatic adjustment needs to be made to the current model configuration. If it is further found that there are multiple gear values corresponding to the average humidity value of 2, which is less than the actual load level of 3, it means that the division value of the average humidity value of the two gears 2 and 3 is too large, resulting in a lot of calculated data being less than the average humidity value of 1940 corresponding to the 2nd gear and falling within the range of the 1-2 gear interval. Therefore, the average humidity threshold corresponding to the 2nd gear needs to be reduced by a preset amplitude, first reduced to 1930, and the weighing level is calculated. The result is as Figure 4As shown, the number of weighing levels equal to the actual load level is 7, which is still less than 80% of the total data. Then, further check the humidity difference. Since the humidity difference division values for the second and third gears are on the small side, the data falls within the range of the first to second gears. Therefore, the range corresponding to the second gear needs to be increased by a certain amplitude, changing 40 to 50, and then recalculate the weighing level. The result is as Figure 5 shown, meeting the weighing accuracy requirement. At this time, write the corrected data into the program to complete the adjustment of the weighing data.

[0061] Embodiment 2

[0062] This embodiment is a weighing correction method for a dryer applying the dryer weighing correction system described in Embodiment 1, including the following steps: S1. During the heating stage, the humidity detection module detects the humidity of the loaded clothes to obtain the humidity value; S2. The control module calculates the humidity difference and the average humidity value based on the humidity value, and calculates the weighing level by calculating the gear values corresponding to the obtained average humidity value and humidity difference. Compare the obtained weighing level with the actual load level, and judge the correct value ratio of the weighing level data calculated in multiple groups that conforms to the actual load level; S3. After the judgment is completed, select whether to adjust the average humidity threshold and the humidity difference threshold according to the judgment result. If an adjustment is made, automatically write the adjusted average humidity value threshold and humidity difference threshold into the program.

[0063] Specifically, in this method, the stage of detecting humidity is placed at the very beginning of the heating stage. In this state, the motor is in a stable state of rotating forward all the time, which can avoid the problem that the motor stops rotating, resulting in unstable output detection of the humidity value and inaccurate weighing level calculated therefrom. The humidity detection module detects the humidity of the loaded clothes and transmits the detected data to the control module, where these data are calculated to obtain multiple humidity differences and average humidity values. Then, calculate the weighing levels corresponding to the detected data according to the thresholds stored in the storage module and their corresponding gear values, and compare them with the actual load level corresponding to the weight of the loaded clothes. Judge the proportion of the data that conforms to the actual load level. If the proportion is lower than the preset proportion, the stored average humidity threshold and humidity difference threshold need to be adjusted, and when the adjustment is completed and it meets the model of this configuration, write the adjusted data into the program.

[0064] This embodiment also provides a dryer, which applies a weighing calibration method for a dryer as described in this embodiment. When the dryer applies the above weighing calibration method, it can calibrate the data stored in the dryer for weighing. Before the dryer leaves the factory, the data entered in the dryer is calibrated. During the calibration process, the data actually detected by the dryer multiple times is compared with the data pre-stored in the dryer, and the stored data is gradually adjusted. Until the stored data conforms to the actual situation, the data is written into the program of the dryer, and the weighing data of the dryer is calibrated before leaving the factory. At this time, the weighing program of the dryer will meet the actual requirements.

[0065] Embodiment III

[0066] This embodiment is a method for using data scatter to determine whether to adjust the stored average humidity threshold and humidity difference threshold. The calculation formula for data scatter is:

[0067] S 2 =[(x1 - x) 2 +(x2 - x) 2 +……+(x n - x) 2 / n

[0068] Where S is the scatter we calculated, x1, x2, x n are the weighing levels obtained from weighing calculations, x is the load weighing level, and n is the total number of measured weighing levels.

[0069] When calculating the data scatter, first set the maximum value S1 of the data scatter, determine that the standard number x is the actual load weighing level, then substitute the calculated weighing level and weighing quantity into the formula for calculation, and compare the calculated data S with the maximum value of the data scatter we pre-set. If the calculated value S is greater than the set maximum value S1, it is determined that the stored threshold needs to be adjusted.

[0070] The adjustment method is the same as that in Embodiment I. After determining that the threshold needs to be adjusted, adjust the threshold to be adjusted in the determined adjustment direction, and calculate the data scatter again after the adjustment is completed. When the calculated data scatter is less than or equal to the preset maximum value of the data scatter, it means that the weighing accuracy requirement is met after the adjustment, and the calibrated data is automatically written into the program for storage to complete the adjustment of the weighing data.

[0071] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of this patent, without departing from the scope of the technical solution of the present invention, can make some changes or modifications using the technical content prompted above to form equivalent embodiments of equivalent changes. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.

8. A weighing calibration method for a dryer, characterized in that, Apply a weighing correction system for a dryer as described in any one of claims 1 to 7 to correct the weighing parameters of the dryer.

9. A method for weighing correction of a dryer according to claim 8, characterized in that, It includes the following steps: S1. During the heating stage, the humidity detection module detects the humidity of the loaded clothes to obtain a humidity value; S2. The control module performs operations based on the humidity value to obtain a humidity difference and an average humidity value, and calculates the weighing level by calculating the gear values corresponding to the obtained average humidity value and humidity difference, compares the obtained weighing level with the actual load level, and judges the correct value ratio of the weighing level data calculated in multiple groups that conform to the actual load level; S3. After the judgment is completed, select whether to adjust the average humidity threshold and humidity difference threshold according to the judgment result. If adjustment is performed, then automatically write the adjusted average humidity value threshold and humidity difference threshold into the program.
