DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] The traditional method of drying degree detection is to set a preset value after several standard experiments, and then compare the information fed back by the sensor during product use to judge the current drying situation. However, temperature and humidity are easily affected by external factors such as foam sticking to the sensor or water vapor condensing on the sensor, and as time accumulates, wrong judgments may occur, resulting in the drying time being too long or too short.

[0028] One of the core concepts of the embodiment of the present invention is to compare the eccentricity generated by the clothes falling in the drum with the preset value, and to obtain the distance by adding a displacement sensor to the upper part of the hanging spring. When the washing and drying machine is swung, the distance is measured to obtain the eccentricity value, and then the data is analyzed and compared to output the drying time for control. The eccentricity itself is a stable physical quantity, which will not change with other physical quantities such as temperature and humidity, and has strong anti-interference ability.

[0029] Reference Figure 1 , shows a flow chart of steps of an embodiment of a clothes drying control method of the present invention, and the clothes drying control method may specifically include the following steps: Step 101, when the washing machine enters a drying stage, detecting displacement data of the drum of the washing machine; Wherein, the displacement data is determined by the displacement of a suspension spring, and the suspension spring is arranged on the drum of the washing machine; When the washing machine dries clothes in the drying stage, the displacement data of the drum of the washing machine can be detected. The displacement data is used to characterize the deviation of the drum of the washing machine in the drying stage.

[0030] The judgment of the drying stage of the washing machine can be judged by time judgment, previous washing program judgment, temperature detection and humidity detection. The time judgment method can judge whether the washing is completed and enter the drying stage according to the preset washing program and time. When the washing time reaches the preset value, the washing machine will automatically stop the washing stage and enter the drying stage. The previous washing program judgment can be judged by the completion of the previous washing program. For example, if the previous washing program of the drying stage is a dehydration program, it can be detected when the dehydration program is completed to determine that it has entered the drying stage. Temperature detection can also be performed. Before entering the drying stage, the washing machine will detect the temperature in the barrel. When the temperature in the barrel reaches a range suitable for drying, the washing machine will determine that it can enter the drying stage. This temperature range is usually preset according to the material and drying requirements of the clothes. Humidity detection detects the humidity in the barrel through a humidity sensor. When the humidity drops to a certain level, the washing machine will also determine that it can enter the drying stage.

[0031] Step 102, determining the eccentricity according to the displacement data; Based on the change in displacement data, the current eccentricity of the washing machine drum is determined.

[0032] Step 103, determining a drying time based on the eccentricity; Based on the size of the eccentricity, the drying time corresponding to the current size of the eccentricity is determined.

[0033] Step 104, controlling the washing machine to dry the clothes for the drying time.

[0034] The washing machine is controlled to run continuously in the drying stage until the drying time has elapsed, and the washing machine dries the clothes within a time corresponding to the drying time.

[0035] The embodiment of the present invention detects the displacement data of the drum of the washing machine when the washing machine enters the drying stage; determines the eccentricity according to the displacement data; determines the drying time based on the eccentricity; and controls the washing machine to dry the clothes to the drying time. The eccentricity is determined by detecting the displacement data of the drum of the washing machine, and the degree of drying of the clothes is characterized by the eccentricity. The anti-interference ability is stronger, the data is more stable and accurate, the degree of drying of the clothes is accurately determined by the eccentricity, and then the drying time can be more accurately determined, and the clothes are dried, which can improve the drying efficiency.

[0036] Reference Figure 2 , shows a flow chart of steps of another embodiment of a clothes drying control method of the present invention, wherein a hanging spring is provided on the drum of the washing machine, and the connecting end of the hanging spring and the drum is a follower end; the other end of the hanging spring is a fixed end. Figure 3 Point A is the fixed end, which only moves with the outer tube itself. Point B is the follower end, which not only moves with the outer tube, but also moves due to the expansion and contraction of the suspension spring. The dynamic eccentricity can be obtained by dynamically changing the follower end and the fixed end. Figure 4 , after the washing machine enters the drying stage, the drum of the washing machine is offset due to rolling. The solid line is the drying state position, and the dotted line is the original position.

[0037] The clothes drying control method may specifically include the following steps: Step 201, when the washing machine enters a drying stage, detecting the displacement of the follower end and determining the displacement data of the drum of the washing machine; When the washing machine enters the drying stage, the displacement of the follower end is detected by a position sensor at the follower end, and the displacement data of the drum of the washing machine is determined by the displacement of the follower end.

[0038] For the position sensor, a potentiometer position sensor, a magnetoelectric position sensor, an optical position sensor, etc. can be used; the embodiments of the present invention do not make specific limitations. The potentiometer position sensor moves along a resistor through a movable sliding contact to change the resistance value, thereby generating a voltage signal output proportional to the position. The magnetoelectric position sensor uses changes in the magnetic field to detect the position. Common Hall effect sensors include a magnet that is usually installed on the object to be measured. When the magnet approaches the sensor, a magnetic field is generated, and the Hall element inside the sensor generates a voltage signal that is proportional to the magnetic field strength, thereby obtaining the current position of the object. Optical position sensors use photoelectric elements to accurately measure the position.

[0039] Displacement data can be found at Figure 5 When the load is 1 kg, the maximum amplitude stretching is in the low-speed stage, but it is still less than 20 mm. In the high-speed stage, it is generally around 6 mm and will not exceed 2 cm.

[0040] Step 202, determining the eccentricity according to the displacement data; The corresponding eccentricity of the washing machine drum can be determined based on the size of the displacement data.

[0041] In an optional embodiment of the present invention, the step of determining the eccentricity according to the displacement data comprises: Sub-step S2021, calculating the eccentric distance according to the fixed point coordinates of the fixed end and the displacement data; In the embodiment of the present invention, the eccentric distance may be calculated using the position deviation between the fixed point coordinates of the fixed end and the displacement data.

[0042] Furthermore, the step of calculating the eccentric distance according to the fixed point coordinates of the fixed end and the displacement data comprises: Sub-step S20211, calculating a first distance difference between the fixed point coordinates of the fixed end and the displacement data; The distance value between the fixed point coordinates of the fixed end and the displacement data, ie, the first distance difference, can be calculated.

[0043] Specifically, the fixed point coordinates of the fixed end include: a fixed point horizontal coordinate and a fixed point vertical coordinate; the displacement data includes a horizontal offset coordinate and a vertical offset coordinate; the step of calculating the first distance difference between the fixed point coordinates of the fixed end and the displacement data includes: calculating the first difference between the fixed point horizontal coordinate and the horizontal offset coordinate; calculating the second difference between the fixed point vertical coordinate and the vertical offset coordinate; determining the absolute value of the first difference and the absolute value of the second difference as the first distance difference.

[0044] In an embodiment of the present invention, the fixed point coordinates of the fixed end include the fixed point horizontal coordinate and the fixed point vertical coordinate; the displacement data includes the horizontal offset coordinate and the vertical offset coordinate. The fixed point horizontal coordinate, the fixed point vertical coordinate, the horizontal offset coordinate and the vertical offset coordinate are position coordinates in the same coordinate system. If the fixed point horizontal coordinate, the fixed point vertical coordinate, the horizontal offset coordinate and the vertical offset coordinate are not position coordinates in the same coordinate system, coordinate conversion can be performed in advance so that the fixed point horizontal coordinate, the fixed point vertical coordinate, the horizontal offset coordinate and the vertical offset coordinate are in the same coordinate system.

[0045] The difference between the horizontal coordinate of the fixed point and the horizontal offset coordinate can be calculated as the first difference. The difference between the vertical coordinate of the fixed point and the vertical offset coordinate can be calculated as the second difference. The absolute value of the first difference and the absolute value of the second difference are used as the first distance difference.

[0046] Sub-step S20212, obtaining no-load preset displacement data; The no-load preset displacement data can be obtained. The no-load preset displacement data can be determined in advance based on experiments. For example, the following can be collected in advance: Figure 3 The coordinates of point A in ) and the dynamically changing coordinates of point B ( ).

[0047] The experiment was conducted under the conditions of ambient temperature 23±2℃, ambient humidity 60%±5%, 220V, 50Hz power supply. After washing, drying and spinning, the displacement sensor was read after gradually increasing the load ( ), and record the corresponding time ( ). The time-related data is recorded as the no-load preset displacement data ( ) and store the drying time T corresponding to each point in the storage of the washing and drying machine one by one, so as to prepare data reserve for real-time processing.

[0048] Sub-step S20213, calculating a second distance difference between the fixed point coordinates of the fixed end and the no-load preset displacement data; Accordingly, the distance between the fixed point coordinates of the fixed end and the no-load preset displacement data can be calculated, which is the second distance difference.

[0049] Specifically, the unloaded preset displacement data includes a transverse unloaded coordinate and a longitudinal unloaded coordinate, and the step of calculating the second distance difference between the fixed point coordinate of the fixed end and the unloaded preset displacement data includes: calculating the third difference between the horizontal coordinate of the fixed point and the transverse unloaded coordinate; calculating the fourth difference between the vertical coordinate of the fixed point and the longitudinal unloaded coordinate; and determining the absolute value of the third difference and the absolute value of the fourth difference as the second distance difference.

[0050] In an embodiment of the present invention, the unloaded preset displacement data includes a horizontal unloaded coordinate and a vertical unloaded coordinate. The fixed point horizontal coordinate, the fixed point vertical coordinate, the horizontal unloaded coordinate and the vertical unloaded coordinate are position coordinates in the same coordinate system. If the fixed point horizontal coordinate, the fixed point vertical coordinate, the horizontal unloaded coordinate and the vertical unloaded coordinate are not position coordinates in the same coordinate system, coordinate conversion can be performed in advance so that the fixed point horizontal coordinate, the fixed point vertical coordinate, the horizontal unloaded coordinate and the vertical unloaded coordinate are in the same coordinate system.

[0051] The difference between the horizontal coordinate of the fixed point and the horizontal unloaded coordinate can be calculated as the third difference. The difference between the vertical coordinate of the fixed point and the longitudinal unloaded coordinate can be calculated as the fourth difference. The absolute value of the third difference and the absolute value of the fourth difference are used as the second distance difference.

[0052] Sub-step S20214: determining an eccentric distance based on the first distance difference and the second distance difference.

[0053] The first distance difference and the second distance difference may be combined to determine the eccentricity distance.

[0054] Specifically, the step of determining the eccentric distance based on the first distance difference and the second distance difference includes: calculating a first square difference between the absolute value of the first difference and the absolute value of the third difference; calculating a second square difference between the absolute value of the second difference and the absolute value of the fourth difference; calculating the sum of the first square difference and the second square difference; and determining the square root of the sum as the eccentric distance.

[0055] The difference between the absolute value of the first difference and the absolute value of the third difference can be calculated, and the square value corresponding to the difference can be determined to be the square value of the first difference. The difference between the absolute value of the second difference and the absolute value of the fourth difference can be calculated, and the square value corresponding to the difference can be determined to be the square value of the second difference. The sum of the square value of the first difference and the square value of the second difference is calculated; and the square root of the sum is determined to be the eccentric distance.

[0056] Sub-step S2022, determining the eccentricity according to the eccentricity distance.

[0057] Specifically, the step of determining the eccentricity based on the eccentric distance includes: determining half the value of the eccentric distance as the eccentricity.

[0058] In summary, the calculation of eccentricity can be expressed by the following formula:

[0059] Among them, e is the eccentricity, d is the eccentric distance, is the first difference, is the second difference, is the third difference, is the fourth difference, is the lateral offset coordinate, is the vertical offset coordinate, is the horizontal coordinate of the fixed point, is the ordinate of the fixed point, is the lateral unloaded coordinate, is the longitudinal no-load coordinate.

[0060] Step 203, determining a drying time based on the eccentricity; The drying time can be determined according to the size of the eccentricity.

[0061] You can refer to Figure 6 The upper curve is the drying time under different temperatures and loads (0.5, 1, 2, 3, 5, 7), and the lower curve is the drying time under the same eccentricity and load; the actual drying time is determined based on the eccentricity.

[0062] Specifically, the step of determining the drying time based on the eccentricity includes: judging whether the eccentricity is not less than a preset eccentricity threshold; in response to the eccentricity being less than the preset eccentricity threshold, determining the drying time to be the preset time; in response to the eccentricity being not less than the preset eccentricity threshold, determining the drying time to be the sum of the preset time and the compensation time; the compensation time is determined based on the difference between the eccentricity and the preset eccentricity threshold.

[0063] It can be determined whether the magnitude of the eccentricity is not less than a preset eccentricity threshold. When the eccentricity is less than the preset eccentricity threshold, it means that the current clothes are in a relatively dry state, and the clothes can be dried by using the shortest preset drying time. In response to the eccentricity being less than the preset eccentricity threshold, the drying time can be determined to be the preset time. When the eccentricity is not less than the preset eccentricity threshold, it means that the current clothes are relatively wet, and the preset time cannot dry the clothes. In response to the eccentricity being not less than the preset eccentricity threshold, the drying time can be determined to be the sum of the preset time and the compensation time; the compensation time is determined based on the difference between the eccentricity and the preset eccentricity threshold. The compensation time can be determined by dynamic compensation.

[0064] The preset eccentricity threshold can be set according to actual conditions, and the embodiment of the present invention does not specifically limit the specific value.

[0065] That is, it can be expressed by the following formula:

[0066] in, is the drying time, T is the preset time, is the compensation duration, e is the eccentricity, is the preset eccentricity threshold, is the total compensation time. When the eccentricity is greater than the preset threshold, the preset time can be used for drying. When the drying time is set to zero, the compensation time is used, and since the preset drying time has been performed before, the drying time is the sum of the preset time and the compensation time. The compensation time adopts dynamic compensation. That is, the eccentricity is measured while the time is modified until the inner drum rotates during the drying process, and the eccentricity is measured in real time until the first condition of the above formula is met. Return to the first condition of the above formula and update it. The eccentricity value of the first record in the record is recorded as .

[0067] In addition, the real-time data can be stored in the internal memory and the corresponding initial value can be updated, which can reduce the steps required for the next wash and improve the washing efficiency of the whole machine.

[0068] Step 204, controlling the washing machine to dry the clothes for the drying time.

[0069] The drying time of the washing machine for drying clothes can be controlled, thereby achieving the drying of clothes and effectively improving the drying efficiency.

[0070] In order to make the implementation process of the embodiments of the present invention clear to those skilled in the art, the following reference is made to Figure 7 Let me explain this with an example: After the process starts, data is collected. After the displacement data is obtained, the data is converted into eccentricity, and then compared with the preset value. If it matches the preset value, the preset value T0 is output. If it does not match, the drum starts to rotate and dry at the same time until it meets the preset eccentricity. At this time, T0 is output and the drum rotation time is included in the preset value. The next round of the program will read it directly to reduce the process time.

[0071] It should be noted that, for the sake of simplicity, the method embodiments are described as a series of action combinations, but those skilled in the art should be aware that the embodiments of the present invention are not limited by the order of the actions described, because according to the embodiments of the present invention, certain steps can be performed in other orders or simultaneously. Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions involved are not necessarily required by the embodiments of the present invention.
