Description

Technical Field

[0001] This disclosure relates to the field of clothes dryers, and more particularly to a method, apparatus and clothes dryer for uniform drying control. Background Technology

[0002] As people's living standards continue to improve, clothes dryers are receiving more and more attention and love, and their popularity and usage rate have greatly increased.

[0003] Currently, all dryer modes aim to dry clothes quickly and reduce air-drying time. However, in actual use, clothes often dry unevenly. This is mainly because the clothes are not sufficiently tumbled and shaken in the drum. Currently, dryers are generally controlled to operate with constant parameters to shake the clothes. The intelligence and adaptability of the shaking process are poor, resulting in poor drying effect and affecting the user experience. Summary of the Invention

[0004] To address the aforementioned technical problems, this disclosure provides a method, apparatus, and dryer for uniform drying control, which improves the intelligence and adaptability of the clothes shaking process and enhances the clothes shaking effect of the dryer at different drying stages to optimize the clothes drying effect.

[0005] In a first aspect, embodiments of this disclosure provide a method for controlling the uniform drying of a clothes dryer, including:

[0006] Obtain the temperature value of the clothes in the dryer;

[0007] The drying stage of the dryer is determined based on the temperature value and the fluctuation value of the temperature value; the drying stage includes a first drying stage and a second drying stage.

[0008] The operation of the dryer is controlled according to the drying stage it is in.

[0009] Therefore, when clothes are rapidly tumbling inside the dryer, the temperature value of the clothes surface is acquired. Based on the temperature value and its fluctuation, the drying stage of the dryer can be determined. The operation of the dryer can then be controlled according to the drying stage. In other words, different operating parameters can be controlled for the tumbling operation of the dryer depending on the drying stage, which improves the correspondence between the tumbling operation and the drying stage. This enhances the intelligence and adaptability of the clothes tumbling process, improves the tumbling effect of the dryer on clothes at different drying stages, and optimizes the drying effect.

[0010] In some embodiments, the degree of drying of the clothes corresponding to the first drying stage to the second drying stage increases sequentially;

[0011] The step of determining the drying stage of the dryer based on the temperature value and the fluctuation value of the temperature value includes:

[0012] If the temperature value is determined to be less than a first preset temperature value and the fluctuation value is determined to be less than a first preset fluctuation value, the dryer is determined to be in the first drying stage.

[0013] If the fluctuation value is determined to be greater than the first preset fluctuation value, it is determined that the dryer is in the second drying stage.

[0014] In some embodiments, the drying stage further includes a third drying stage, wherein the degree of drying of the clothes corresponding to the first drying stage to the third drying stage increases sequentially;

[0015] The step of determining the drying stage of the dryer based on the temperature value and the fluctuation value of the temperature value includes:

[0016] If the temperature value is determined to be greater than the second preset temperature value, the dryer is determined to be in the third drying stage.

[0017] In some embodiments, controlling the operation of the dryer according to the drying stage it is in includes:

[0018] In the second drying stage, the dryer is controlled to reverse based on the fluctuation value and the rate of change of the fluctuation value within a preset interval.

[0019] Therefore, when the dryer is in the second drying stage, the fluctuation of the clothing temperature value is used to determine whether the clothes in the dryer are sufficiently shaken. If it is determined that the clothes in the dryer are not sufficiently shaken, the dryer is reversed in time. This helps to ensure that the clothes in the dryer are fully shaken, which can avoid problems such as large clothes being partially dried wrapping around small clothes that are not yet dried, which can lead to uneven drying. This optimizes the uniformity of drying and thus improves the drying effect of the dryer.

[0020] In some embodiments, controlling the dryer to reverse based on the fluctuation value and the rate of change of the fluctuation value within a preset interval includes:

[0021] When the fluctuation value decreases, and / or the rate of change of the fluctuation value within the preset interval is greater than the preset rate of change, the dryer is controlled to reverse.

[0022] In some embodiments, controlling the dryer to reverse includes:

[0023] The dryer is controlled to rotate forward at a speed greater than the dryer rotates in reverse.

[0024] This avoids the problem of clothes being thrown against the inner wall of the dryer drum due to excessive reverse speed, which would otherwise affect the evenness of drying.

[0025] In some embodiments, controlling the operation of the dryer according to the drying stage it is in includes:

[0026] During the first drying stage, the dryer is controlled to reverse at first preset time intervals;

[0027] In the third drying stage, the dryer is controlled to reverse at second preset time intervals; wherein the first preset time is less than the second preset time.

[0028] In some embodiments, after the third drying stage, the method further includes:

[0029] The dryer is controlled to stop drying based on the fluctuation value; the dryer is controlled to stop drying when the fluctuation value is less than a fourth preset fluctuation value for a period of time longer than a preset duration; and / or,

[0030] The system obtains the humidity value of the drying space inside the dryer and controls the dryer to stop drying based on the humidity value; when the humidity value is less than a preset humidity value, the system controls the dryer to stop drying.

[0031] Secondly, embodiments of this disclosure also provide a uniform drying control device for a clothes dryer, comprising:

[0032] A temperature acquisition module is used to acquire the temperature value of the clothes in the dryer;

[0033] A stage determination module is used to determine the drying stage of the dryer based on the temperature value and the fluctuation value of the temperature value; wherein the drying stage includes at least a first and a second drying stage;

[0034] The operation control module is used to control the operation of the dryer according to the drying stage it is in.

[0035] Therefore, when clothes tumble rapidly inside the dryer, the temperature value of the clothes' surface is obtained. Based on the temperature value and its fluctuation, the drying stage of the dryer can be determined. When the dryer is determined to be in the second drying stage, the temperature fluctuation of the clothes is used to determine whether the clothes have been sufficiently shaken. If the clothes are not sufficiently shaken, the dryer is reversed in time. This helps to ensure that the clothes are fully shaken and avoids problems such as large clothes being partially dried wrapping around undried small clothes, which can lead to uneven drying. This optimizes the uniformity of drying and thus improves the drying effect of the dryer.

[0036] In some embodiments, the operation control module is specifically used to control the dryer to reverse during the second drying stage based on the fluctuation value and the rate of change of the fluctuation value within a preset interval.

[0037] Thirdly, embodiments of this disclosure also provide a clothes dryer, comprising:

[0038] The processor and memory, wherein the processor executes steps of a uniform drying control method for any of the dryers provided in the first aspect by invoking programs or instructions stored in the memory.

[0039] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0040] The uniform drying control method for a clothes dryer provided in this disclosure includes acquiring the temperature value of the clothes in the dryer; determining the drying stage of the dryer based on the temperature value and its fluctuation; the drying stage includes at least a first and a second drying stage; and controlling the operation of the dryer according to the drying stage. Thus, when clothes are rapidly tumbling inside the dryer, by acquiring the temperature value of the surface of the clothes, and then determining the drying stage based on the temperature value and its fluctuation, the operation of the dryer can be controlled according to the drying stage. That is, different operating parameters can be controlled for the tumbling operation of the dryer depending on the drying stage, improving the correspondence between the tumbling operation and the drying stage, thereby improving the intelligence and adaptability of the clothes tumbling process, and enhancing the tumbling effect of the dryer on clothes at different drying stages to optimize the drying effect. When the dryer is in the second drying stage, the temperature fluctuation of the clothes is used to determine whether the clothes have been sufficiently shaken. If the clothes are not sufficiently shaken, the dryer is reversed in time. This helps to ensure that the clothes are fully shaken and avoids problems such as large clothes being partially dried wrapping around smaller clothes that are not yet dried, which can lead to uneven drying. This optimizes the uniformity of drying and thus improves the drying effect of the dryer. Attached Figure Description

[0048] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0049] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0050] When clothes are rapidly tumbling inside the dryer, this embodiment of the present disclosure obtains the temperature of the clothes in the dryer, and then determines the drying stage of the dryer based on the temperature value and temperature fluctuation trend. When it is determined that the dryer is in the second drying stage, it judges whether the clothes in the dryer are sufficiently shaken based on the fluctuation of the clothing temperature value, and promptly controls the dryer to reverse when it is determined that the clothes in the dryer are not sufficiently shaken. This helps to ensure that the clothes in the dryer are fully shaken, and avoids problems such as some large clothes being partially dried wrapping around undried small clothes, which can lead to uneven drying. This optimizes the uniformity of drying clothes in the dryer, thereby optimizing the drying effect of the dryer.

[0051] The following is in conjunction with the appendix Figures 1 to 5 The present disclosure provides an exemplary description of the uniform drying control method, apparatus, and dryer for clothes dryers according to embodiments.

[0052] Figure 1 This is a flowchart illustrating a method for controlling the uniform drying of a clothes dryer according to an embodiment of this disclosure. This method is applicable to applications requiring control over the drying uniformity of the clothes dryer. This method can be executed by a uniform drying control device for a clothes dryer provided in this embodiment, which can be implemented using software and / or hardware. Figure 1 As shown, the method includes the following steps:

[0053] S101. Obtain the temperature value of the clothes in the dryer.

[0054] Figure 2 This is a front perspective view of a clothes dryer provided in an embodiment of this disclosure. Figure 2 As shown, a thermopile temperature sensor 1 is installed inside the dryer, for example. The thermopile temperature sensor 1 can be installed and fixed at any position around the outer perimeter of the drum in the dryer. Figure 2 As shown, a receiving groove 2 can be set at the position of the thermopile temperature sensor 1 for installation and fixing in the dryer. The thermopile temperature sensor 1 is placed in the receiving groove 2, which can avoid the friction of clothes or other structures inside the dryer against the lens of the thermopile temperature sensor 1. The receiving groove 2 needs to be open in the direction of the clothes to be tested so as to expose the structure of the thermopile temperature sensor 1 for emitting and collecting infrared light, so as to realize the temperature detection of the surface of the clothes inside the dryer.

[0055] Specifically, when the dryer starts its drying program, the thermopile temperature sensor continuously monitors the temperature of the clothes, especially their surfaces, within the dryer. For example, as the clothes tumble inside the dryer drum, the thermopile temperature sensor detects the temperature of the clothes, particularly their surfaces, within its probe range, either at a single point or in an array, enabling rapid temperature acquisition. Based on this, the surface temperature of the clothes can be obtained while they are rapidly tumbling within the dryer.

[0056] In other embodiments, an infrared sensor similar to a thermopile temperature sensor may be installed inside the dryer to collect the temperature value of the clothes, or other technical means known to those skilled in the art may be used to obtain the temperature value of the clothes. This disclosure does not impose specific limitations on these embodiments.

[0057] It should be noted that the preferred embodiments of this disclosure are as follows: Figure 2 As shown, the thermopile temperature sensor 1 is placed in the upper area of ​​the dryer, which facilitates the thermopile temperature sensor to emit infrared rays to the clothes in the dryer to detect the temperature of the clothes, which helps to improve the accuracy of detecting the temperature of the clothes in the dryer.

[0058] S102. Determine the drying stage of the dryer based on the temperature value and the temperature fluctuation value; wherein the drying stage includes at least the first drying stage and the second drying stage.

[0059] The temperature fluctuation value is calculated by subtracting the highest and lowest temperatures detected by the thermopile temperature sensor from the clothes in the dryer within any given time interval. Alternatively, in other embodiments, the ratio of the highest to the lowest temperature detected by the thermopile temperature sensor can be used to measure the temperature fluctuation trend.

[0060] In some embodiments, the drying stage includes a first drying stage, a second drying stage, and a third drying stage, with the degree of drying of the clothes increasing sequentially from the first drying stage to the third drying stage. Specifically, the temperature fluctuation trend of the clothes in the dryer is related to the degree of drying of the clothes in the dryer. Therefore, the drying stage can be divided into multiple stages based on the temperature value and temperature fluctuation value of the clothes in the dryer. Taking three stages as an example, they are the first drying stage, the second drying stage, and the third drying stage. The degree of drying of the clothes in the third drying stage is greater than that in the second drying stage, and the degree of drying of the clothes in the second drying stage is greater than that in the first drying stage. For example, the first drying stage can be the beginning drying stage, the second drying stage can be the intermediate drying stage, and the third drying stage can be the end drying stage. The critical values ​​of the degree of drying of the clothes corresponding to the first drying stage, the second drying stage, and the third drying stage can be set according to the user's requirements for the degree of drying of the clothes. This embodiment of the disclosure does not specifically limit this.

[0061] In some embodiments, the degree of drying of clothes corresponding to the first drying stage to the second drying stage increases sequentially; the step of determining the drying stage of the dryer based on the temperature value and the fluctuation value of the temperature value includes: determining that the dryer is in the first drying stage when the temperature value is less than a first preset temperature value and the fluctuation value is less than a first preset fluctuation value; and determining that the dryer is in the second drying stage when the fluctuation value is greater than the first preset fluctuation value.

[0062] In some embodiments, the drying stage further includes a third drying stage, wherein the degree of drying of the clothes corresponding to the first drying stage to the third drying stage increases sequentially; the step of determining the drying stage of the dryer based on the temperature value and the temperature fluctuation value includes: determining that the temperature value is greater than a second preset temperature value, and determining that the dryer is in the third drying stage.

[0063] Specifically, the first drying stage represents the initial drying phase of the dryer. At this stage, the clothes in the dryer are relatively damp and their temperature is low. Because the clothes are damp, they are prone to tangling. Regardless of the degree of shaking or loosening of the clothes, the temperature fluctuation detected by the temperature sensor is very small. Based on this, a first preset temperature value and a first preset fluctuation value can be set. Then, based on the comparison logic between the temperature value of the clothes in the dryer and the first preset temperature value, and the comparison logic between the temperature fluctuation value of the clothes in the dryer and the first preset fluctuation value, it can be determined whether the dryer is in the first drying stage. Specifically, the determination logic is that when the temperature value of the clothes in the dryer is less than the first preset temperature value, and when the temperature fluctuation value of the clothes in the dryer is less than the first preset fluctuation value, it can be determined that the dryer is in the first drying stage. The first preset temperature value and the first preset fluctuation value can be adaptively set according to the requirements of the uniform drying control method for the dryer provided in this embodiment.

[0064] Specifically, after the dryer completes the first drying stage, it enters the second drying stage. At this stage, the dryer contains both dried and undried clothes. The dried clothes have a higher temperature, while the undried clothes have a lower temperature, resulting in significant temperature fluctuations among the clothes. Therefore, a first preset fluctuation value can be set. The dryer's operation in the second drying stage is then determined by comparing the temperature fluctuations of the clothes with this first preset fluctuation value. Specifically, the determination logic is that the dryer is in the second drying stage when the temperature fluctuations of the clothes are greater than the first preset fluctuation value. The first preset fluctuation value can be adaptively set according to the requirements of the uniform drying control method for the dryer provided in this embodiment. Alternatively, a second preset fluctuation value can be set, which is greater than the first preset fluctuation value. The dryer's operation in the second drying stage is then determined by comparing the temperature fluctuations of the clothes with this second preset fluctuation value. Specifically, the dryer is in the second drying stage when the temperature fluctuations of the clothes are greater than the second preset fluctuation value. The second preset fluctuation value can be adaptively set according to the requirements of the uniform drying control method for the dryer provided in the embodiments of this disclosure.

[0065] Specifically, after the dryer completes the second drying stage, it enters the third drying stage. At this point, most of the clothes in the dryer are dried, and the temperature of the clothes in the dryer is relatively high, setting a second preset temperature value. The system can then determine whether the dryer is in the third drying stage based on a comparison logic between the temperature of the clothes in the dryer and the second preset temperature value. Specifically, the determination logic is that if the temperature of the clothes in the dryer is greater than the second preset temperature value, it can be determined that the dryer is in the third drying stage. The second preset temperature value can be adaptively set according to the requirements of the uniform drying control method for the dryer provided in this embodiment.

[0066] It should be noted that after the dryer enters the second drying stage, because some clothes are dried to a higher degree and some are dried to a lower degree, the temperature fluctuation is larger when the clothes are shaken more thoroughly and smaller when the clothes are not shaken more thoroughly. The larger temperature fluctuation of the clothes in the dryer after entering the second drying stage as described in the aforementioned embodiments refers to the second preset fluctuation value being larger than the first preset fluctuation value. Additionally, the second preset temperature can be set to be higher than the first preset temperature. In some embodiments, before determining the drying stage of the dryer based on the temperature value and the temperature fluctuation value, the humidity value of the drying space inside the dryer can also be obtained; the drying stage of the dryer is determined by combining the temperature value, the temperature fluctuation value, and the humidity value.

[0067] Specifically, based on the description of clothing drying at different stages in the above embodiments, the humidity level in the drying space inside the dryer varies depending on the drying stage. Therefore, to improve the accuracy of determining the current drying stage, the humidity level in the drying space inside the dryer is acquired in real time, while simultaneously obtaining the temperature and temperature fluctuation values ​​of the clothing in the dryer. Referring to the above embodiments, the humidity level in the drying space inside the dryer is highest in the first drying stage, followed by the second drying stage, and lowest in the third drying stage. Therefore, by combining the temperature and temperature fluctuation values ​​of the clothing in the dryer with the humidity level of the drying space inside the dryer to determine the current drying stage, the accuracy of determining the current drying stage can be improved.

[0068] S103. Control the operation of the dryer according to the drying stage it is in.

[0069] Therefore, when clothes are rapidly tumbling inside the dryer, the temperature value of the clothes surface is acquired. Based on the temperature value and its fluctuation, the drying stage of the dryer can be determined. The operation of the dryer can then be controlled according to the drying stage. In other words, different operating parameters can be controlled for the tumbling operation of the dryer depending on the drying stage, which improves the correspondence between the tumbling operation and the drying stage. This enhances the intelligence and adaptability of the clothes tumbling process, improves the tumbling effect of the dryer on clothes at different drying stages, and optimizes the drying effect.

[0070] In some embodiments, controlling the operation of the dryer according to the drying stage in which the dryer is located includes: in the second drying stage, controlling the dryer to reverse according to the fluctuation value and the rate of change of the fluctuation value within a preset interval.

[0071] Specifically, referring to the above embodiment, when it is determined that the dryer has entered the second drying stage, some clothes in the dryer have been dried, while others are still damp. At this time, continued rotation of the inner drum can easily cause some of the larger, dried clothes to wrap around smaller, undried clothes, leading to a sudden decrease in the temperature fluctuation of the clothes in the dryer. This means the rate of change of the fluctuation value within the preset interval increases, i.e., the slope of the fluctuation value increases. Therefore, when the dryer is in the second drying stage, the rate of change of the fluctuation value within the preset interval is obtained. When it is determined that there is a problem of clothes wrapping in the dryer based on the fluctuation value and the rate of change of the fluctuation value within the preset interval, the dryer is controlled to reverse, which can solve the problem of clothes wrapping in the dryer. Alternatively, obtaining the rate of change of the fluctuation value within the preset interval can be done by obtaining the fluctuation values ​​at the start and end times of the preset interval and then calculating the rate of change, or by continuously obtaining the fluctuation values ​​and incorporating the preset interval time into the calculation of the rate of change.

[0072] In some embodiments, controlling the dryer to reverse based on the fluctuation value and the rate of change of the fluctuation value within a preset interval includes: controlling the dryer to reverse when the fluctuation value decreases and / or the rate of change of the fluctuation value within the preset interval is greater than a preset rate of change.

[0073] Specifically, referring to the above embodiments, when the dryer is in the second drying stage, it is easy for large items of clothing that have already been dried to wrap around undried smaller items of clothing. On the one hand, when large items of clothing wrap around smaller items of clothing, it is necessary to control the dryer to reverse the direction of rotation to resolve this issue. On the other hand, when large items of clothing wrap around smaller items of clothing, it can easily cause a sudden decrease in the temperature fluctuation of the clothing in the dryer, i.e., an increase in the rate of change of the fluctuation value within a preset interval, i.e., an increase in the slope of the fluctuation value. Therefore, the dryer can be reversed based on the fluctuation value and / or the rate of change of the fluctuation value within a preset interval. Specifically, the control logic is that when the fluctuation value decreases and / or the rate of change of the fluctuation value within a preset interval is greater than a preset rate of change, the dryer is reversed to improve the aforementioned clothing wrapping situation and optimize the uniformity of clothing drying. In addition, if the fluctuation value decreases but the rate of decrease slows down, the drying process is considered normal and the dryer is not reversed. The preset rate of change can be adaptively set based on the requirements of the uniform drying control method for the dryer provided in this embodiment.

[0074] For example, the slope of the temperature fluctuation value can be set to be acquired and calculated every 4 minutes, that is, to observe the temperature fluctuation trend. When the temperature fluctuation value tends to decrease and the slope is large, it is considered that the clothes have wrapped up, causing the temperature fluctuation value to suddenly decrease. At this time, the dryer can be controlled to turn on reverse to improve the aforementioned clothes wrapping situation and optimize the uniformity of clothes drying.

[0075] In other embodiments, the slope of the temperature fluctuation value can be set to be acquired and calculated every 3 minutes (i.e., to observe the temperature fluctuation trend), or the slope of the temperature fluctuation value can be set to be acquired and calculated every 2 minutes (i.e., to observe the temperature fluctuation trend). This disclosure does not specifically limit this.

[0076] It should be noted that the shorter the interval between acquiring the fluctuation value, the more accurate the acquired temperature fluctuation trend of the clothes, which improves the timeliness of controlling the dryer to reverse. This helps to promptly resolve the problem of clothes being wrapped up in the dryer, ensuring that the clothes are fully shaken out and improving the uniformity of drying. This embodiment of the present disclosure solves the problem of large items of clothing wrapping around smaller items of clothing in the dryer by controlling the dryer to reverse based on the temperature fluctuation value and temperature fluctuation trend of the clothes in the dryer during the second drying stage.

[0077] When using a thermopile sensor to detect clothing temperature, the detection principle involves sensing the surface temperature of the clothing. Since the thermopile sensor is in a fixed position and the dryer drum rotates at a constant speed, if the clothing is not sufficiently shaken within the drum, the thermopile sensor will continuously sense the temperature at the same location on the clothing instead of across the entire garment. This results in minimal temperature variation and fluctuations. Therefore, by analyzing the magnitude of the temperature changes detected by the thermopile sensor, it's possible to determine whether the clothing is adequately shaken within the drum, allowing for the implementation of a reverse-shaping control method to optimize the clothing's shaking effect.

[0078] In some implementations, the reverse rotation speed of the dryer is controlled to be less than the forward rotation speed.

[0079] Specifically, referring to the above embodiment, when clothes become tangled in the dryer, activating the dryer's reverse rotation program reverses the drum, thus resolving the problem of clothes becoming tangled in the dryer. While controlling the dryer's reverse rotation, ensuring the reverse speed is lower than the forward speed prevents excessive reverse speed from generating a large centrifugal force that could throw clothes against the inner wall of the drum, affecting the evenness of drying.

[0080] It should be noted that when the dryer is reversed, it cannot blow air into the drum, resulting in low drying efficiency. Therefore, while addressing the issue of clothes getting tangled in the dryer, the reverse rotation time should be minimized to improve drying efficiency.

[0081] In some embodiments, controlling the operation of the dryer according to the drying stage it is in includes: in the first drying stage, controlling the dryer to reverse at a first preset time interval; in the third drying stage, controlling the dryer to reverse at a second preset time interval; wherein the first preset time is less than the second preset time.

[0082] Specifically, when the dryer is in the third drying stage, most of the clothes in the dryer have been dried, and the problem of clothes getting tangled in the dryer is unlikely. At this time, the dryer can be controlled to reverse at preset intervals. For example, in the third drying stage, the dryer can be set to reverse every second preset time interval, such as ten minutes.

[0083] It should be noted that when the dryer is in the third drying stage, the drying process is about to end. Therefore, the step of controlling the dryer to reverse at preset intervals is to prevent clothes from getting tangled in the dryer, and is not a necessary step. Furthermore, the first drying stage is the initial drying stage, at which time the clothes are relatively damp, the surface temperature is low, the clothes are prone to tangling, and temperature fluctuations are small. A timed reverse control logic can be used at first preset intervals, such as every two minutes. This embodiment does not specifically limit the first and second preset times; they can be set according to the drying requirements.

[0084] In some embodiments, after the third drying stage, the process further includes:

[0085] The dryer is controlled to stop drying based on the fluctuation value; wherein, when the time when the fluctuation value is less than the fourth preset fluctuation value is greater than the preset duration, the dryer is controlled to stop drying; and / or, the humidity value of the air in the dryer is obtained and the dryer is controlled to stop drying based on the humidity value; wherein, when the humidity value is less than the preset humidity value, the dryer is controlled to stop drying.

[0086] Specifically, when the temperature fluctuation of the clothes in the dryer is detected to be less than a fourth preset fluctuation value, and the period during which the fluctuation value remains less than the fourth preset fluctuation value is greater than a preset duration (i.e., the temperature fluctuation of the clothes remains small for a long time), it can be considered that the clothes in the dryer are dry, and at this time, the dryer is controlled to turn off the drying function. For example, the preset duration can be set to 6 minutes. If the temperature fluctuation of the clothes in the dryer is continuously detected to be less than the fourth preset fluctuation value for more than 6 minutes, it can be determined that the clothes in the dryer are dry, and the dryer is further controlled to turn off the drying function.

[0087] Alternatively, a humidity sensor can be installed in the dryer to detect the humidity of the air in the drying space. When the detected humidity value is lower than a preset value, the clothes are considered to be dry, and the dryer is then turned off. In other embodiments, other humidity acquisition devices known to those skilled in the art can also be installed in the dryer, which are not specifically limited here or described in detail.

[0088] Alternatively, if the time it takes for the temperature fluctuation of the clothes in the dryer to be less than the fourth preset fluctuation value is greater than the preset duration, and the humidity value of the air in the dryer is less than the preset humidity value, the dryer will turn off the drying function.

[0089] The fourth preset fluctuation value and the preset humidity value can be adaptively set based on the requirements of the uniform drying control method for the dryer provided in this embodiment of the present disclosure.

[0090] In the above embodiments, the second preset temperature value is greater than the first preset temperature value. Among the second preset fluctuation value, the third preset fluctuation value, and the fourth preset fluctuation value, the first preset fluctuation value is the largest, and the fourth preset fluctuation value is the smallest. The relationship between the first preset fluctuation value and the third preset fluctuation value is uncertain, and their specific values ​​can be adaptively set according to the needs of the drying stage of the dryer.

[0091] Based on the above embodiments, Figure 3 The illustration shows a schematic flowchart of a uniform drying control method for a clothes dryer provided in this embodiment of the present disclosure. This method can also be executed by the uniform drying control device for the clothes dryer provided in this embodiment of the present disclosure.

[0106] This disclosure embodiment obtains the temperature value of the clothes in the dryer, and then determines the drying stage of the dryer based on the temperature value and its fluctuation. When determining the second drying stage, it judges whether the clothes in the dryer are sufficiently shaken based on the temperature fluctuation. If it determines that the clothes are not sufficiently shaken, it promptly controls the dryer to reverse, which helps to ensure that the clothes in the dryer are fully shaken. This avoids problems such as partially dried large items of clothing wrapping around undried small items of clothing, which can lead to uneven drying. This optimizes the uniformity of drying and thus improves the drying effect of the dryer. Exemplarily, the dryer described in this disclosure embodiment can be a venting dryer, a heat pump dryer, or a condenser dryer. This disclosure embodiment does not limit the specific type of dryer.
