[0068] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0069] In the drying process of the drying equipment, the real-time temperatures of the air inlet pipe and the air outlet pipe of the inner drum are first determined. Then, based on these temperatures, the real-time temperature difference is determined. Finally, the operating status of the drying equipment is controlled based on this temperature difference. Therefore, by controlling the operating status of the drying equipment through the real-time temperature difference, the operating status can be controlled in real time. Compared to related technologies that control the drying process solely based on drying time, this method can reduce the risk of over-drying the goods.

[0070] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0077] Figure 6 This is a block diagram illustrating a control device for a drying apparatus according to an exemplary embodiment. Detailed Implementation

[0078] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0079] It should be noted that all actions involving the acquisition of signals, information, or data in this disclosure are carried out in compliance with the relevant data protection laws and policies of the country where the location is situated, and with authorization from the owner of the relevant device.

[0080] Drying equipment is used to remove moisture from materials after washing and dehydration. In related technologies, the following methods are commonly used to control the operating status of drying equipment:

[0081] Figure 1 This is a schematic diagram illustrating the process of a drying device performing a drying operation in the first related technology. Figure 1 The drying process is as follows: Before the drying equipment performs the drying operation, a maximum drying heating time is set on the drying equipment based on the weight of the item to be dried. The actual total drying heating time is compared with the maximum drying heating time. When the actual total drying heating time is greater than or equal to the maximum drying heating time, the item to be dried is cooled, and the drying equipment stops drying. When the actual total drying heating time is less than the preset drying heating time, it is determined whether the item to be dried is already dried. If the item is already dried, the item to be dried is cooled, and the drying equipment stops drying. Otherwise, a new actual total drying heating time is obtained, and this process continues until the new actual total drying heating time is greater than or equal to the maximum drying heating time. In this case, the item to be dried is cooled, and the drying equipment stops drying.

[0082] In the second related technology, a humidity sensor is used to determine the degree of dryness of the material to be dried in the drying equipment, thereby controlling the operating status of the drying equipment.

[0083] The inventors discovered that in the first related technology, setting the preset total drying and heating time based on the weight of the dried item, and controlling the operating status of the drying equipment according to the relationship between the actual total drying and heating time and the preset total drying and heating time, may result in the dried item being over-dried.

[0084] In the second related technology, the degree of dryness of the dried material is determined by a humidity sensor. However, the addition of a humidity sensor increases manufacturing costs.

[0085] Therefore, in order to solve the above problems, this disclosure provides a control method and device for drying equipment, drying equipment, and storage medium, which controls the operating status of the drying equipment by real-time temperature difference, thereby reducing the occurrence of over-drying of the dried items.

[0086] Figure 2 This is a flowchart illustrating a control method for a drying apparatus according to an exemplary embodiment, such as... Figure 2 As shown, the control method used in the terminal includes the following steps.

[0087] In step S201, the real-time temperature of the air inlet pipe of the inner cylinder and the real-time temperature of the air outlet pipe of the inner cylinder are determined during the operation of the drying equipment.

[0088] In step S202, the real-time temperature difference is determined based on the real-time temperature of the air inlet pipe and the real-time temperature of the air outlet pipe.

[0089] In step S203, the operating status of the drying equipment is controlled according to the real-time temperature difference.

[0090] It should be understood that the real-time temperature of the air inlet pipe can be the real-time temperature collected from the air inlet pipe of the inner cylinder of the drying equipment, and the real-time temperature of the air outlet pipe can be the real-time temperature collected from the air outlet pipe of the inner cylinder of the drying equipment. Controlling the operating status of the drying equipment can be controlling the drying equipment to stop the drying operation, controlling the drying equipment to perform the drying operation, or adjusting the remaining drying heating time on the drying equipment. In this embodiment, no specific limitation is made.

[0091] In the above control method, the operating status of the drying equipment can be controlled in real time by controlling the temperature difference. Compared with the related technology that only controls the drying time, the over-drying of the dried items can be reduced.

[0092] Among possible methods, controlling the operating status of the drying equipment based on real-time temperature differences includes:

[0093] Determine the parameter information of the material to be dried in the drying equipment. The parameter information includes at least one of the load of the material to be dried and the material information of the material to be dried, as well as the current total drying and heating time.

[0094] The target temperature difference is determined based on the correspondence between the parameter information and the target temperature difference; different parameter information corresponds to different target temperature differences.

[0095] The operating status of the drying equipment is controlled based on the numerical relationship between the target temperature difference and the real-time temperature difference.

[0096] It should be understood that one parameter of the dried material corresponds to one target temperature difference, and multiple parameter information corresponds to multiple target temperature differences. The multiple target temperature differences may be different or partially the same. Among them, the parameter information of the dried material may include at least one of the following: the load of the dried material, the material information of the dried material, and the actual total drying and heating time. The load of the dried material can be the weight of the dried material before washing and dehydration.

[0097] By identifying the correspondence between the parameters of the material to be dried and the target temperature difference, the target temperature difference can be determined. Furthermore, the operating status of the drying equipment can be controlled based on the numerical relationship between the target temperature difference and the real-time temperature difference.

[0098] In one possible approach, the drying stop threshold of the drying equipment can be determined first based on the load and material information of the items to be dried. When the real-time temperature difference is less than the target temperature difference, the operating status of the drying equipment can be controlled based on the numerical relationship between the real-time temperature difference and the drying stop threshold.

[0099] It should be understood that the drying stop threshold can be used to characterize the critical threshold between the dried and undried state of the material. The drying stop threshold can be related to the load and material information of the material in the drying equipment; one load corresponds to one drying stop threshold, and different loads correspond to different drying stop thresholds. Similarly, one material information corresponds to one drying stop threshold, and different material information corresponds to different drying stop thresholds. The material information of the material to be dried can be pure cotton, acrylic fiber, etc.

[0100] In possible ways, the operating status of the drying equipment is controlled based on the numerical relationship between the real-time temperature difference and the drying stop threshold, including:

[0101] When the real-time temperature difference is less than or equal to the drying stop threshold, control the drying equipment to stop the drying operation;

[0102] When the real-time temperature difference exceeds the drying stop threshold, the drying equipment is controlled to perform a drying operation.

[0103] It should be understood that when the real-time temperature difference is less than or equal to the drying stop threshold, it indicates that the material is dried, and the drying equipment can be controlled to stop the drying operation. When the real-time temperature difference is greater than the drying stop threshold, it indicates that the material is not dried, and the drying equipment can be controlled to continue the drying operation.

[0104] Therefore, by controlling the operating status of the drying equipment through the numerical relationship between the real-time temperature difference and the drying stop threshold, the accuracy of the control of the drying equipment's operating status can be improved, thereby reducing the occurrence of over-drying of the dried goods and ensuring that the drying equipment stops drying when the goods are already dried.

[0105] In other possible ways, when the real-time temperature difference is greater than or equal to the target temperature difference, the load moisture content and humidity information of the drying equipment can be determined. Then, based on the load moisture content and humidity information, the drying heating time to be dried is determined. Finally, based on the drying heating time to be dried, the remaining drying heating time of the drying equipment is adjusted, and based on the adjusted remaining drying heating time, the drying equipment is controlled to perform the drying operation.

[0106] It should be understood that the load moisture content information can be seen as the percentage of moisture content in the dried material after a period of drying and heating. The humidity information can be seen as the percentage of humidity inside the drying drum after a period of drying operation.

[0107] It should be understood that, such as Figure 3 As shown, in the third related technology, the drying process of the drying equipment is as follows: Before the drying equipment performs the drying operation, the curve formula of time t versus temperature T1 for all loads under drying conditions is obtained through experimental testing, and the obtained curve formula is stored in the main control board of the drying equipment. When the drying equipment performs the drying operation, the real-time inner cylinder temperature value T2 is obtained, and the set temperature value T1 is determined according to the load, the actual total drying and heating time t, and the stored curve formula. When the inner cylinder temperature value T2 is greater than or equal to the set temperature value T1, the drying equipment is controlled to stop the drying operation. When the inner cylinder temperature value T2 is less than the set temperature value T1, the inner cylinder temperature value T2 and the set temperature value T1 are re-determined until the re-determined inner cylinder temperature value T2 is greater than or equal to the re-determined set temperature value T1, at which point the drying equipment is controlled to stop the drying operation.

[0108] This method primarily controls the drying equipment's operation by relating the actual inner cylinder temperature (T2) to the preset temperature (T1). However, it lacks control over the actual drying time, potentially leading to frequent jumps in the remaining drying time based on a fixed value. This can cause misunderstandings among users regarding the remaining drying time. For example, if the remaining drying time is 1 minute and the item is still undried, the remaining time is adjusted to 11 minutes based on the fixed value of 10 minutes, and the drying process continues. Similarly, if the remaining time returns to 1 minute and the item is still undried, the remaining time is readjusted to 11 minutes based on the fixed value of 10 minutes, and the drying process continues, and so on, until the item is completely dried. Therefore, the remaining drying time can fluctuate frequently based on a fixed value, leading to user misunderstandings about the actual remaining drying time.

[0109] To address this issue, embodiments of this disclosure can determine the load moisture content and humidity information of the drying equipment when the real-time temperature difference is greater than or equal to the target temperature difference. Then, based on this information, the remaining drying heating time is determined, allowing for adjustment of the remaining drying heating time. For example, if the remaining drying heating time is 1 minute and the item is not yet dried, the remaining drying heating time is increased by the remaining drying heating time, and the drying operation continues. When the remaining drying heating time returns to 1 minute, if the item is already dried, the drying operation stops. If the item is not yet dried, the load moisture content and humidity information within the drying equipment are re-acquired. Based on this re-acquired information, a new drying heating time is determined, and the remaining drying heating time is increased by this new time. This process continues until the item is completely dried, at which point the drying operation stops.

[0110] It should be understood that when the remaining drying heating time is 1 minute, and the item still needs 30 minutes to be dried, if the remaining drying heating time is readjusted to 11 minutes based on a fixed value of 10 minutes according to the third related technology, the remaining drying heating time on the drying equipment needs to be adjusted three times consecutively to ensure the item is dried. However, according to the method provided in this embodiment, based on the load moisture content and humidity information of the drying equipment, the required drying heating time can be determined to be 30 minutes. Therefore, based on the required drying heating time of 30 minutes, the remaining drying heating time of the drying equipment is readjusted to 31 minutes, and the drying operation continues. The remaining drying heating time on the drying equipment only needs to be adjusted once to ensure the item is dried.

[0111] Therefore, compared to the method of adjusting based on a fixed duration value in the third related technology, this method can reduce the frequent jumps in drying and heating time and display the remaining drying and heating time more accurately.

[0112] Among possible approaches, the method also includes: after controlling the drying equipment to perform a drying operation, controlling the drying equipment to cycle through the following operations:

[0113] Re-determine the real-time temperature of the air inlet pipe, the real-time temperature of the air outlet pipe, and the parameter information of the material to be dried in the drying equipment during the operation of the drying equipment;

[0114] Based on the newly determined real-time temperatures of the inlet and outlet ducts, a new real-time temperature difference is determined.

[0115] Based on the preset difference relationship and the redefined parameter information, a new target temperature difference is determined;

[0116] Determine the numerical relationship between the new real-time temperature difference and the new target temperature difference and the drying stop threshold, and control the drying equipment to stop drying operation when the new real-time temperature difference is less than the new target temperature difference and less than the drying stop threshold.

[0117] In other words, when the real-time temperature difference exceeds the drying stop threshold, or when the real-time temperature difference exceeds the target temperature difference and the remaining drying heating time of the drying equipment is adjusted, the drying equipment can be controlled to continue the drying operation. After controlling the drying equipment to continue the drying operation, the steps of the above embodiments can be repeated to control the operating status of the drying equipment until the drying equipment stops the drying operation.

[0118] Indicatively, the real-time temperature of the air inlet pipe of the inner cylinder, the real-time temperature of the air outlet pipe of the inner cylinder, and the parameter information of the dried material in the drying equipment can be redefined. By redefined, a new real-time temperature difference and a new target temperature value can be determined. Based on the new real-time temperature difference, the new target temperature value, and the drying stop threshold, the operating status of the drying equipment can be controlled until the drying equipment stops drying.

[0119] By repeatedly executing the above steps, the operating status of the drying equipment can be controlled in real time, reducing the occurrence of over-drying of the dried goods.

[0120] Among the possible approaches, the methods also include:

[0121] Determine the preset total drying and heating time and the actual total drying and heating time of the drying equipment;

[0122] Determine the real-time temperature of the air inlet pipe and the air outlet pipe of the inner cylinder during the operation of the drying equipment, including:

[0123] When the actual total drying and heating time is less than the preset total drying and heating time, determine the real-time temperature of the air inlet pipe and the real-time temperature of the air outlet pipe during the operation of the drying equipment.

[0124] It should be understood that the preset total drying and heating time can be the longest continuous drying and heating time based on the parameter information of the material to be dried. When the actual total drying and heating time does not reach the preset total drying and heating time, the real-time temperature of the air inlet pipe and the air outlet pipe of the inner cylinder of the drying equipment can be obtained. Then, the real-time temperature difference can be determined by obtaining the real-time temperature of the air inlet pipe and the air outlet pipe, and the operating status of the drying equipment can be controlled according to the real-time temperature difference, so as to realize the real-time control of the drying equipment and reduce the occurrence of over-drying of the material.

[0125] Among the possible approaches, the methods also include:

[0126] When the actual total drying and heating time is greater than or equal to the preset total drying and heating time, the drying equipment will be stopped.

[0127] When the actual total drying and heating time is greater than or equal to the preset total drying and heating time, it indicates that the continuous drying and heating time of the material in the drying equipment has reached the maximum time. Regardless of whether the material is actually dried, the drying equipment needs to be stopped. Therefore, the drying equipment can be stopped when the actual total drying and heating time is greater than or equal to the preset total drying and heating time.

[0128] Figure 4 This is a flowchart illustrating a control method for a drying apparatus according to another exemplary embodiment, such as... Figure 4 As shown, the control method includes the following steps.

[0129] Step S400: Set different preset temperature difference values ​​according to different parameter information.

[0130] Step S401: The inner drum of the drying equipment rotates, and the real-time temperature of the air inlet pipe of the inner drum, the real-time temperature of the air outlet pipe of the inner drum, and the preset temperature difference are recorded.

[0131] Step S402: Drying and heating begins.

[0132] Step S403: Determine the real-time temperature difference based on the real-time temperature of the air inlet pipe and the real-time temperature of the air outlet pipe.

[0133] Step S404: Determine whether the real-time temperature difference is less than the target temperature difference. If the real-time temperature difference is less than the target temperature difference, proceed to step S415; otherwise, proceed to step S405.

[0136] Step S407: Determine whether the new real-time temperature difference is less than the new target temperature difference. If the new real-time temperature difference is less than the new target temperature difference, proceed to step S415; otherwise, proceed to step S408.

[0137] Step S408: Increase the drying heating time according to the new parameter information and continue the drying operation.

[0138] Step S409: Resample the real-time temperature of the air inlet duct and the real-time temperature of the air outlet duct to determine the new real-time temperature difference.

[0139] Step S410: Determine whether the new real-time temperature difference is less than the new target temperature difference. If the new real-time temperature difference is less than the new target temperature difference, proceed to step S415; otherwise, proceed to step S411.

[0140] Step S411: Increase the drying heating time according to the new parameter information and continue the drying operation.

[0141] Step S412: Resample the real-time temperature of the air inlet duct and the real-time temperature of the air outlet duct to determine the new real-time temperature difference.

[0142] Step S413: Determine whether the new real-time temperature difference is less than the new target temperature difference. If the new real-time temperature difference is less than the new target temperature difference, proceed to step S415; otherwise, proceed to step S414.

[0144] Step S415: Continue the drying operation according to the drying heating time displayed on the drying equipment, and proceed to step S416.

[0145] Step S416: Determine whether the real-time temperature difference is less than the drying stop threshold. If the real-time temperature difference is less than the drying stop threshold, stop the drying operation; otherwise, proceed to step S417.

[0146] Step S417: Determine whether the actual total drying and heating time is greater than the preset total drying and heating time. If the actual total drying and heating time is greater than the preset total drying and heating time, stop the drying operation; otherwise, proceed to step S412.

[0147] The specific implementation methods for each of the above steps have been described in detail above and will not be repeated here. It should also be understood that, for the sake of simplicity, the above method embodiments are described as a series of actions; however, those skilled in the art should understand that this disclosure is not limited to the order of actions described above. Furthermore, those skilled in the art should also understand that the embodiments described above are preferred embodiments, and the steps involved are not necessarily essential to this disclosure.

[0148] The above method allows for real-time control of the drying equipment's operation based on the temperature difference, reducing the risk of over-drying. By controlling the drying process according to the relationship between the real-time temperature difference and the drying stop threshold, the drying operation can be stopped once the goods are properly dried, improving the accuracy of determining the drying status.
