[0002] Because dryers can dry clothes quickly after washing, allowing users to wear them immediately, they are becoming increasingly popular and have a growing market share.
[0003] However, during the drying process of clothes dryers, abnormal drying phenomena are prone to occur. There are often many reasons for abnormal drying functions. If the cause is not accurately identified, for example, if the check for a certain abnormal cause is overlooked, it may be mistakenly judged as normal drying function, and the drying function will continue to run. As a result, after the drying program ends, it will be found that the clothes are not dry. This not only wastes energy, but also reduces the user experience.
[0004] Accordingly, there is a need in the art for a new control method for clothing processing equipment to solve the problem of how to accurately determine the abnormality of the drying function when a dryer is in operation. Summary of the Invention

[0007] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, after the step of "when the rate of change is less than the first preset rate of change and the current weight of the clothing is greater than or equal to a preset percentage of the initial weight of the clothing, the drying function is determined to be abnormal", the control method further includes: determining the faulty part that causes the drying function to be abnormal; and sending a prompt message that the faulty part is operating abnormally.
[0008] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the step of "determining the fault location that causes the drying function to malfunction" further includes: determining whether the fan is operating abnormally; if it is abnormal, then determining that the fault location causing the drying function to malfunction is the fan.
[0009] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the step of "determining whether the fan is operating abnormally" further includes: determining whether the fan speed is less than the preset speed and the time less than the preset speed is greater than a first set time during the drying process; if so, then the fan is determined to be operating abnormally.
[0010] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the step of "determining the fault location that causes the drying function to malfunction" further includes: determining whether the air outlet of the air duct is abnormal; if it is abnormal, then determining that the fault location causing the drying function to malfunction is the air duct.
[0011] In the preferred technical solution of the control method for the above-mentioned clothing processing equipment, the step of "determining whether the air outlet of the air duct is abnormal" further includes: determining whether the air duct pressure is greater than the preset pressure; if so, then determining that the air outlet of the air duct is abnormal.
[0012] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the step of "determining the fault location that causes the drying function to malfunction" further includes: determining whether the heating element is malfunctioning; if it is malfunctioning, then determining that the fault location causing the drying function to malfunction is the heating element.
[0013] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the step of "determining whether the heating element is abnormal" further includes: determining whether the heating temperature of the heating element is outside the preset range during the drying process and whether the time outside the preset range is longer than a second set time; if so, then the heating element is determined to be abnormal; wherein, when the heating temperature is outside the preset range and the time outside the preset range is longer than the second set time, then the drying function is controlled to stop operating.
[0014] In a preferred embodiment of the control method for the aforementioned clothing processing equipment, after the step of "obtaining the initial weight of the clothing before drying", the control method further includes: determining the air volume of the fan and the heating power of the heating element based on the initial weight of the clothing; controlling the fan to operate according to the air volume and controlling the heating element to operate according to the heating power when drying begins; after the step of "determining the rate of change of clothing weight within a preset time based on the real-time obtained clothing weight", the control method further includes: adjusting the air volume and the heating power based on the rate of change.

[0017] When the rate of change of clothing weight within a preset time is less than the first preset rate of change, and the current clothing weight is greater than or equal to a preset percentage of the initial clothing weight, it indicates that the weight of the clothing has not been effectively reduced as the drying time increases, the clothing still contains a lot of moisture, and the clothing can no longer be dried. This situation can be judged as a malfunction of the drying function. This control method can make timely and accurate judgments of malfunctions of the drying function when the clothing processing equipment is running, thereby facilitating the next step of operation. For example, it can directly provide feedback to the user on the malfunction of the drying function, so that the user can deal with it in a timely manner, or the clothing processing equipment can directly perform fault diagnosis, thereby avoiding the clothing processing equipment from continuing to dry the clothing when the drying function is malfunctioning, which not only wastes the user's time but also wastes energy.

[0024] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. Those skilled in the art can make adjustments as needed to adapt to specific applications.
[0025] It should be noted that in the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0026] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0027] To address the problem of accurately identifying drying function malfunctions in existing clothes dryers, this invention provides a control method for a clothing processing device. The specific form of this clothing processing device includes various methods, such as a drying box, a clothes dryer, or a shoe dryer. It is understood that, as... Figure 1 As shown, the garment processing equipment includes a drying shell 113, a fan 13, and a heating element 14, etc. The drying shell 113 forms a drying chamber 111. The heating element 14 can be a heating tube or a PTC heating plate / rod, etc. The heating element 14 can be installed in a tube body 16. Of course, the tube body 16 can be replaced by a heating shell, etc. The connection methods of the above components include various methods: for example, the drying shell 113 is... Figure 1 When the dryer drum of the dryer is installed, the dryer drum is provided with an installation port (not shown in the figure). The air inlet of the fan 13 is connected to the installation port, and the air outlet of the fan 13 is connected to the air inlet of the pipe body 16. The air outlet of the pipe body 16 extends from the opening of the dryer drum into the drying chamber 111. Alternatively, a drying port can be provided on the dryer drum, and the air outlet of the pipe body 16 can be connected to the drying port, etc. Or refer to Figure 2The drying box includes an outer shell 11 and a partition plate 12. The partition plate 12 is located inside the outer shell 11 and divides the outer shell 11 into a drying chamber 111 and a component mounting chamber 112. The portion of the outer shell 11 corresponding to the drying chamber 111 is connected to the partition plate 12 to form the aforementioned drying shell. A fan 13 and a heating element 14 are located in the component mounting chamber 112. The air inlet of the fan 13 is connected to the outside air, and the air outlet of the fan 13 is connected to the air inlet of the pipe body 16. The air outlet of the pipe body 16 is connected to the mounting port (not shown in the figure) on the partition plate 12. An air outlet is provided on the outer shell 11 corresponding to the drying chamber 111.
[0028] In this invention, the internal channels of the fan 13 and the pipe body 16 together form an air duct. Of course, the specific configuration of the air duct can be adjusted. For example, when the air inlet of the fan 13 is connected to the installation port of the drying cylinder or the outside air through the connecting pipe 18, the connecting pipe 18, the fan 13 and the internal channels of the pipe body 16 together form an air duct. These simple changes do not deviate from the principle of this invention and are all within the protection scope of this invention. In this invention, a pressure sensor is provided in the air duct to detect the pressure in the air duct.
[0029] When the clothing processing equipment is a drying box, a weighing element such as a weighing sensor 15 can be installed on the partition plate 12, and a storage mesh plate 17 is connected to the inner peripheral wall of the outer shell 11 corresponding to the drying chamber 111. The weighing sensor 15 is connected to the bottom side of the storage mesh plate 17, so that the weighing sensor 15 can weigh the clothes after they are placed on the storage mesh plate 17.
[0030] When the clothing processing equipment is a dryer, refer to Figure 1 Under the action of the fan 13, the air in the drying chamber 111 is introduced into the pipe body 16 through the air inlet of the fan 13, and is heated by the heating element 14 in the pipe body 16 to form hot air. The hot air enters the drying chamber 111 through the air outlet of the pipe body 16. After the hot air dries the clothes in the drying chamber 111, it forms cold air. The cold air is introduced again through the air inlet of the fan 13, and so on.
[0031] When the garment processing equipment is a dryer box, refer to Figure 2 Under the action of the fan 13, outside air is introduced into the pipe body 16 through the air inlet of the fan 13, and is heated by the heating element 14 in the pipe body 16 to form hot air. The hot air enters the drying chamber 111 through the air outlet of the pipe body 16. After the hot air dries the clothes in the drying chamber 111, it forms cold air. The cold air is discharged through the air outlet, and then outside air is introduced again by the fan 13, and so on.
[0032] Reference Figure 3 The control method of the garment processing equipment of the present invention includes the following steps.
[0033] Step S100: Obtain the initial weight of the clothes before drying.
[0034] There are several methods for obtaining the weight of clothing. For example, the clothing processing equipment is equipped with a weighing sensor. When the clothing is placed in the drying chamber, the weight of the clothing can be obtained through the weighing sensor. When the clothing processing equipment is a dryer or a washer-dryer combo, the weight of the clothing can also be obtained through fuzzy weighing.
[0035] There are several ways to obtain the initial weight of clothes before drying: for example, when the drying program is started, the initial weight of the clothes can be obtained directly through a weighing sensor or fuzzy weighing; or, when the clothes processing equipment is a washer-dryer combo, the clothes can be weighed after the dehydration program is completed, and the obtained weighing data can be stored in the computer board. When the drying program is started, the stored weighing data can be directly retrieved and used as the initial weight of the clothes.
[0036] After obtaining the initial weight of the clothes before drying, the control method further includes: determining the air volume of the fan and the heating power of the heating element based on the initial weight of the clothes; and controlling the fan to operate at the air volume and the heating element to operate at the heating power when drying begins.
[0037] After being spun in a washing machine, the moisture content of normal clothing is between 80% and 130%. When the initial weight of the clothing is large, the total moisture content is also high. For example, if the initial weight of the clothing is 600g, a larger air volume and heat are usually required to accelerate the drying effect. For example, an initial air volume of 28cmh and an initial heating element power of 500W are needed to dry the clothing at a higher temperature and air volume, resulting in more water vapor evaporating from the surface of the garment per unit time and a faster drying speed. Conversely, when the initial weight of the clothing is small, the total moisture content is also smaller. For example, if the initial weight of the clothing is 200g, a smaller air volume and heat can be used, such as an initial air volume of 16cmh and an initial heating element power of 300W. This avoids resource waste caused by excessive air volume and heat, and also avoids the phenomenon of clothes being damaged by rapid heat accumulation.
[0038] Therefore, this invention determines the airflow of the fan and the heating power of the heating element based on the initial weight of the clothing. At the start of drying, the fan is controlled to operate at the stated airflow, and the heating element is controlled to operate at the stated heating power. This improves the drying effect, avoids energy waste, and prevents clothing from being damaged by the heat. The clothing processing equipment can pre-store a table showing the initial weight of the clothing, the fan's airflow, and the heating power of the heating element. Once the initial weight of the clothing is determined, the fan's airflow and the heating power of the heating element can be determined. Alternatively, after determining the initial weight of the clothing, the fan's airflow and the heating power of the heating element can also be determined based on empirical formulas.
[0039] Step S200: During the drying process, the weight of the clothes is obtained in real time.
[0040] Understandably, during the drying process, the moisture content of the clothes will decrease as the drying time increases, thus causing the weight of the clothes to change. Real-time acquisition of the weight of the clothes refers to acquiring the weight of the clothes at set intervals, such as every 1 minute or 30 seconds.
[0041] Step S300: Based on the real-time acquired clothing weight, determine the rate of change of clothing weight within a preset time period.
[0042] To illustrate this, let's take a specific example. For instance, if the preset time is 5 minutes, the rate of change of clothing weight within the preset time is determined based on the real-time acquired clothing weight. This could be based on the clothing weight acquired every minute to determine the rate of change of clothing weight within 5 minutes. For example, if the clothing weight acquired in a certain instance is 600g, and the clothing weight is 540g after 5 minutes, then the rate of change of clothing weight is 10%.
[0043] Once the rate of change in clothing weight over a preset time period is determined, the airflow of the fan and the heating power of the heating element can be adjusted based on this rate of change.
[0044] Specifically, if the rate of change of clothing weight within a preset time is greater than the second preset rate of change, the airflow of the fan and the heating power of the heating element remain unchanged. For example, if the rate of change of clothing weight within 5 minutes is greater than 10%, it indicates that the drying effect of the clothing is good, so the airflow of the fan and the heating power of the heating element remain unchanged. If the rate of change of clothing weight within a preset time is less than or equal to the second preset rate of change and greater than or equal to the first preset rate of change, the airflow of the fan and the heating power of the heating element are reduced. For example, if the rate of change of clothing weight within 5 minutes is less than or equal to 10% and greater than or equal to 1%, it indicates that there is excess drying heat. In this case, the airflow of the fan and the heating power of the heating element are reduced. For example, the airflow is reduced from 28 cmh to 26 cmh, and the heating power of the heating element is reduced from 500W to 460W, and so on, until the minimum value is 50% of the initial airflow and heating power of the heating element, after which they no longer change.
[0045] When the rate of change in clothing weight within a preset time is less than a first preset rate of change, and the current clothing weight is less than a preset percentage of the initial clothing weight, the drying function will stop operating. For example, if the rate of change in clothing weight within 5 minutes is less than 1%, and the current clothing weight is less than 80% of the initial clothing weight (e.g., 200g), it can be determined that the clothing is dry, and the drying function will stop operating. This control method effectively protects the clothing material, avoids over-drying, and saves energy. Of course, the settings for the first preset rate of change and the preset percentage can be adjusted based on experience. The current clothing weight refers to the last clothing weight measured within the preset time. For example, when comparing the rate of change in clothing weight within 5 minutes, the current clothing weight is the last clothing weight measured within 5 minutes, such as the 540g mentioned in the previous step.
[0046] Step S400: When the rate of change is less than the first preset rate of change, and the current weight of the clothes is greater than or equal to the preset percentage of the initial weight of the clothes, the drying function is determined to be abnormal.
[0047] For example, if the rate of change in the weight of the clothes within 5 minutes is less than 1%, and the current weight of the clothes is greater than or equal to 80% of the initial weight of the clothes, then the drying function is considered abnormal.
[0048] In other words, if the rate of change of clothing weight within a preset time is less than the first preset rate of change, and the current clothing weight is greater than or equal to a preset percentage of the initial clothing weight, it proves that the weight of the clothing has not been effectively reduced as the drying time increases, the clothing still contains a lot of moisture, and the clothing can no longer be dried. This situation can be judged as a malfunction of the drying function. This control method can make a timely and accurate judgment of the malfunction of the drying function when the clothing processing equipment is running, which facilitates the next step of operation. For example, it can directly feed back the information of the malfunction of the drying function to the user so that the user can deal with it in time, or the clothing processing equipment can directly perform fault diagnosis, thereby avoiding the clothing processing equipment from continuing to dry the clothes when the drying function is malfunctioning, which not only wastes the user's time but also wastes energy.
[0049] Preferably, after step S400, the control method of the present invention further includes: "determining the faulty part causing the drying function malfunction and sending a prompt message indicating that the faulty part is malfunctioning." That is, after determining that the drying function is malfunctioning, the cause of the malfunction is investigated, then the faulty part causing the malfunction is determined, and a prompt message indicating that the faulty part is malfunctioning is sent, for example, by sending an alarm sound. The cause of the malfunction is also fed back to the computer board so that the user can be informed of the cause of the malfunction in a timely manner, replace damaged parts promptly, and avoid other parts from malfunctioning or even causing a fire due to localized high temperatures. This technology greatly ensures product safety.
[0050] If possible, check whether there are any abnormalities in the airflow from the fan, heating element, and air duct.
[0051] First, determine if the fan is operating abnormally. If it is, identify the faulty component causing the drying function malfunction as the fan. There are several methods to determine if the fan is operating abnormally. For example, check if the fan speed is lower than the preset speed during the drying process, and if the time spent below the preset speed exceeds a first set time. If so, the fan is considered to be operating abnormally. The fan speed being lower than the preset speed also includes situations where the fan stops rotating due to a malfunction.
[0052] One of the wires connected to the fan is the speed feedback signal line. During the drying process, if the fan speed is abnormal (stops or is lower than the preset speed), it will send a signal to the computer board. The computer board will record the fan speed. When determining whether the fan is operating abnormally, the controller will obtain the stored historical speed data and then determine whether the fan speed is lower than the preset speed and the time it is lower than the preset speed is longer than a first set time. If so, the clothes will not be dried properly during the drying process, resulting in the above-mentioned abnormal drying function.
[0053] Of course, another method to determine whether the fan is operating abnormally is to determine whether the fan power is less than the preset power and the time the power is less than the preset power exceeds a set time threshold during the drying process. If so, the fan is considered to be operating abnormally. In short, as long as it is possible to determine whether the fan is operating abnormally, the control method of the present invention can be adjusted. These adjustments to the control method do not deviate from the principle of the present invention and are all within the protection scope of the present invention.
[0054] Second, determine if the airflow from the duct is abnormal; if abnormal, identify the duct as the faulty component causing the drying function malfunction. There are several methods for determining if the airflow from the duct is abnormal, such as checking if the duct pressure is greater than the preset pressure; if so, the airflow from the duct is considered abnormal.
[0055] For example, when foreign objects or lint fall into the air duct and cause blockage, or when there are too many clothes in the drying chamber or the clothes are not positioned properly, causing the hot air to be blocked from entering the drying chamber (such as the air outlet of the air duct), the air outlet of the air duct will be blocked, resulting in increased air resistance in the air duct. The pressure sensor in the air duct will detect that the pressure in the air duct has increased, that is, exceeded the preset pressure. In this case, it is determined that the air outlet of the air duct is abnormal. At this time, the fault code can be displayed on the digital tube of the clothing processing equipment.
[0056] Of course, another method to determine whether the airflow from the duct is abnormal is to obtain the fan current and determine whether the fan current is less than the current threshold. If it is less than the current threshold, the fan speed is increased. If the fan current is still less than the current threshold after the fan speed is increased, it proves that the duct is blocked and the airflow from the duct is abnormal. In short, as long as it is possible to determine whether the airflow from the duct is abnormal, the control method of the present invention can be adjusted. These adjustments to the control method do not deviate from the principle of the present invention and are all within the protection scope of the present invention.
[0057] Third, determine if the heating element is malfunctioning; if so, identify the faulty component causing the drying function malfunction as the heating element. Various methods can be used to determine if the heating element is malfunctioning, such as determining if the heating temperature is outside the preset range during the drying process and if the time outside the preset range exceeds a second set time; if so, the heating element is considered malfunctioning; specifically, if the heating temperature is outside the preset range and the time outside the preset range exceeds the second set time, the drying function will be stopped.
[0058] A temperature sensor can be installed in the aforementioned tube to detect the heating temperature of the heating element. During the drying process, if the heating element malfunctions, meaning its temperature is outside the preset range (e.g., too high or too low, exceeding a first preset temperature or falling below a second preset temperature, where the first preset temperature is higher than the second), the temperature sensor will feed the heating temperature data back to the control board. If the heating temperature remains outside the preset range for a period exceeding a second set time, it indicates a heating element malfunction. The controller will then activate the alarm on the clothing processing equipment, disconnect the circuit, and stop the drying function. Therefore, when determining if the heating element is malfunctioning, the controller retrieves stored heating temperature data and checks if the heating temperature has been outside the preset range for a period exceeding a second set time during the drying process. If so, it indicates that the malfunction is caused by the heating element malfunction stopping the drying function.
[0059] Of course, another method to determine whether the heating element is heating abnormally is to check whether there is an alarm record of abnormal heating of the heating element during the drying process. If there is, it is determined that the heating element is heating abnormally. In short, as long as it is possible to determine whether the heating element is heating abnormally, the control method of the present invention can be adjusted. These adjustments to the control method do not deviate from the principle of the present invention and are all within the protection scope of the present invention.
[0060] Preferably, when different parts malfunction, different fault signals are sent to the controller. After receiving the fault signal, the controller will control the alarm to sound, such as emitting a buzzing sound to alert the user. Then, the fault code is displayed on the digital tube, providing the user with timely feedback on the location of the fault so that the user can identify and resolve the problem of blocked air ducts or replace damaged parts. This avoids the failure of other parts or even local high temperature causing a fire. This technology greatly ensures the safety of the product.
[0061] In addition, the present invention also provides a garment processing device, which includes a processor and a memory.
