[0017] In some embodiments of this application, the control method includes:

[0043] In related technologies, dryers without a bottom drain pipe typically have a lower water tank (first water tank) and an upper water tank (second water tank). The first water tank is located at the bottom of the dryer and is used to collect moisture released by the clothes during rotation and heating. The first water tank is usually non-removable, while the second water tank is located above the first water tank, meaning it is usually removable and installed on the top of the dryer for easy emptying by the user. This eliminates the need for a dedicated underground water pipe for the dryer. A drain pump draws water from the first water tank into the second water tank, and once the second water tank reaches a certain level, excess water overflows through a pipe back into the first water tank below.
[0044] While this design was intended to facilitate drainage, water overflow may occur in actual use. When the drainage volume exceeds the backflow capacity of the upper water tank, excessive water may accumulate at the bottom of the tank and overflow from the machine's gaps onto the ground, making the dryer appear to be leaking.
[0045] Existing drainage control methods mainly include timed drainage and float-triggered drainage. Timed drainage starts the drainage pump at fixed time intervals, but it cannot dynamically adjust according to actual water volume, easily leading to energy waste or untimely drainage. Float-triggered drainage triggers drainage based on water level changes, but frequent triggering or conflict with timed drainage can cause frequent pump starts and stops, resulting in dryer overflow and affecting equipment lifespan. Current technology lacks a mechanism for effectively coordinating and handling conflicts between the two drainage modes, especially when both modes are triggered simultaneously, easily causing drainage logic confusion and impacting user experience.
[0046] This application provides a clothes dryer and its control method, control device, and storage medium to solve the problem that the two drainage modes of existing clothes dryers easily cause the drain pump to start frequently, leading to overflow. The following will be described in conjunction with the accompanying drawings. Figures 1-4 Please provide an explanation.
[0047] The control method for a clothes dryer provided in this application embodiment can be applied to a heat pump clothes dryer. The clothes dryer includes a drying drum and a drain pump connected to the drying drum. A float is provided in the water box. When the water level in the water box reaches a certain height, the float closes and conducts.
[0048] It should be noted that the dryer in this embodiment is equipped with two drainage modes to provide safety redundancy. If drainage is only achieved by closing the float, the drying performance will be affected if the float malfunctions or if the dryer is left to close. With timed drainage, timely drainage can be achieved without excessive drainage, which can effectively improve the drying performance. Without timed drainage, more condensation will form inside the drum, affecting the normal use of the dryer.
[0049] For example, please refer to Figure 1 and Figure 2 As shown, Figure 1 and Figure 2 This is a flowchart illustrating the control method for a clothes dryer provided in an embodiment of this application. (See also...) Figure 1 As shown, the control method for a clothes dryer may include:
[0050] S101: In response to the achievement of the first preset condition, control the drainage pump to execute the timed drainage mode;
[0051] In one optional implementation, the first preset condition is a time interval condition, and the timed drainage mode includes: starting the drainage pump every first time interval and continuously draining for a second time interval, that is, under normal circumstances, the drainage pump is controlled to perform timed drainage once every first time interval.
[0052] For example, the timed drainage mode of the dryer can be configured to drain water for 30 seconds every 10 minutes, or it can be configured to other time intervals and drainage durations. This embodiment does not make specific limitations on this.
[0053] S102: In response to the achievement of the second preset condition, control the drainage pump to execute the float-triggered drainage mode; wherein, during the execution of the timed drainage mode, control the drainage pump to suspend the execution of the float-triggered drainage mode.
[0054] In one optional implementation, the second preset condition is a float closure condition, and the float-triggered drainage mode includes: when the float is detected to be continuously connected for a third duration, the drainage pump is started to drain water for a fourth duration; after the drainage is completed, a waiting period of a fifth duration is entered; during the sixth duration at the end of the waiting period, the float is checked again to see if it is continuously connected; the above detection and drainage steps are repeated, and if the number of consecutive repetitions reaches a predetermined alarm threshold, the dryer is controlled to send an alarm message.
[0055] For example, during the drying process of a clothes dryer, the system continuously checks whether the float is engaged. If the float is engaged for 10 consecutive seconds, the drain pump is immediately activated for 20 seconds, followed by a 15-second wait. This process is repeated three times. If the float is engaged for a fourth consecutive 10-second period, a water tank overflow alarm is triggered. In any of the four consecutive checks, if the float's closed duration is less than 10 seconds, the count is cleared. If the float is still detected as closed after three consecutive drain checks, the full water icon on the display will flash. This could indicate a full water tank, a faulty water pump, or a faulty water level switch (float). If the water tank is full, pressing the start / pause button will resume the program; otherwise, turn off the power to troubleshoot.
[0056] The reason the float-triggered drainage mode is designed with a fourth alarm is based on extensive experimental evidence. Excessive drainage could lead to water overflowing from the bottom of the water tank. Premature alarms would cause frequent pauses during drying, forcing users to constantly monitor the machine's operation, significantly impacting the user experience. Therefore, experiments have shown that a fourth alarm effectively addresses these issues, promptly alerting the user when the water tank is full while allowing uninterrupted drying. However, this design presents a significant problem: it cannot distinguish between timed drainage and drainage triggered by the float's closure, potentially confusing the drainage alarm logic.
[0057] In this embodiment, by controlling the drainage pump to pause the execution of the float-triggered drainage mode during the execution of the timed drainage mode, that is, after the drainage pump starts timed drainage, the controller will actively pause or block the judgment and execution of the float-triggered drainage mode. This means that even if the water level rises during this period, causing the float to close (i.e., meeting the second preset condition), the controller will not respond to this trigger signal and will not start the float-triggered drainage mode. This ensures that the timed drainage action is not interrupted by another drainage request, thereby avoiding frequent start-stop of the drainage pump.
[0058] In traditional technology, if the water level rises again shortly after the timed drainage starts, triggering the float to drain, the drainage pump will run continuously, causing a huge impact on the motor and easily damaging it. This invention, through a pause mechanism, ensures the integrity of each drainage action, greatly reducing the number of start-stop cycles and effectively extending the lifespan of the drainage pump and even the entire dryer. Frequent start-stop cycles not only damage the equipment but can also lead to chaotic drainage logic. For example, float-triggered drainage might restart immediately after the timed drainage ends, causing continuous and prolonged drainage, which can easily lead to water overflowing from the dryer. A stable and reliable drainage logic makes the dryer run more smoothly, with a lower failure rate, improving the dryer's reliability and user experience.
[0059] In an optional implementation, the control method further includes: controlling the drainage pump to pause the execution of the float-triggered drainage mode within a first preset time period after the timed drainage mode has been completed.
[0060] In this embodiment, not only is the detection and execution of the float-triggered drainage mode suspended during the execution of the timed drainage mode, but the detection and execution of the float-triggered drainage mode are also suspended for the first preset time after the timed drainage ends, further reducing the possibility of the drainage pump frequently starting to drain water.
[0061] Optionally, the first preset duration can be 20 seconds, 30 seconds or other values, and this embodiment does not specifically limit it.
[0062] In an optional implementation, the control method further includes: controlling the drainage pump to prevent it from starting within a second preset time period, such as 20 seconds, after the timed drainage mode has ended.
[0063] Understandably, given the existing drainage logic issues, it's possible that drainage might occur immediately after the float closes to drain, or immediately after a timed drainage, or vice versa. Either scenario would cause variations in the number of drainage cycles, disrupting the dryer's drainage logic.
[0064] If the float closes immediately after the scheduled drainage, it will drain three times consecutively. However, the float closure detection only meets the trigger condition twice. If drainage occurs again after the float closes for the third time, water may flow out of the machine from the bottom of the water box, indicating a design flaw. Clearly, one more closure is needed to trigger the float closure alarm. This situation only occurs when the drum motor reverses after the scheduled drainage is complete. This causes a large amount of water to accumulate in the water box, leading to float closure. During forward rotation, the airflow draws a lot of water into the duct, which then flows into the water box when the drum motor stops or reverses, causing the float closure alarm to trigger even after the scheduled drainage.
[0065] In one optional implementation, the control method includes: if float conduction is detected within a second preset time period after the end of the timed drainage mode, controlling the dryer to send an alarm message and controlling the dryer to continue operating.
[0066] To address the issue of the float alarm being triggered after the scheduled drainage period ends, a design was specifically implemented where the drainage pump waits 20 seconds after each scheduled drainage cycle before triggering drainage again. Within or before these 20 seconds, if the float is closed, a float icon notification will be triggered, but drainage will not occur, and the machine will continue to operate normally. This float icon notification informs the user that the water tank is full and also prevents accidental triggering that could cause the machine to stop.
[0067] It should be noted that the float icon indicator cannot replace the float alarm, because sometimes users may intentionally or unintentionally leave the water tank full while drying clothes without emptying the water tank in time. This can easily lead to water vapor forming inside the tank, causing dampness and potentially resulting in a safety accident.
[0068] Secondly, setting a 20-second pause after each timed drainage cycle effectively prevents the float from immediately closing and draining after the scheduled drainage, thus avoiding water overflowing the dryer. Understandably, this 20-second pause is experimentally based and has two advantages: firstly, it differentiates from the float drainage pause time, allowing testers to clearly test the drainage logic; secondly, it complements the 30-second timed drainage cycle, ensuring that all water flows from the upper tank to the lower tank when full, preventing overflow. After the 20-second pause, a 10-second float closure check is performed. If the float trigger condition is met at this point, the drainage pump is controlled to drain in float-triggered drainage mode.
[0069] In an optional implementation, the control method includes: when the timed drainage mode and the float-triggered drainage mode are triggered simultaneously, controlling the drainage pump to prioritize the execution of the float-triggered drainage mode, and controlling the drainage pump to cancel the execution of the timed drainage mode.
[0070] It is understandable that simultaneous triggering does not refer to the exact same millisecond in time, but rather that the controller receives activation signals for two modes simultaneously within a very short preset control cycle.
[0071] When both the timed drainage mode and the float-triggered drainage mode are detected to be triggered simultaneously, the drainage pump is controlled to operate in the float-triggered drainage mode to drain water, and the current timed drainage is skipped.
[0072] In an optional implementation, the control method further includes: if a timed drainage mode is triggered during the execution of the float-triggered drainage mode, the drainage pump is controlled to continue executing the float-triggered drainage mode, and the drainage pump is controlled to cancel the execution of the current timed drainage mode.
[0073] Besides the aforementioned timed drainage causing the float to close and begin drainage, there's also the possibility of timed drainage occurring during the four float closure cycles. In this case, timed drainage not only disrupts the drainage rhythm but also interferes with the alarm timing. To address this issue, drainage priorities are set for the two drainage modes. If float drainage occurs, timed drainage is not performed during either the drainage period or the drainage waiting period. If the two times conflict, the current timed drainage is canceled until the next drainage cycle. If float drainage occurs in the next cycle, the current timed drainage is also canceled, and so on. This rational design effectively avoids timed drainage during float closure, preventing frequent pump starts and reducing the possibility of overflow.
[0074] In an optional implementation, the control method further includes: if the first preset condition is detected to be met within a third preset time period, such as 20 seconds, after the float-triggered drainage mode has ended, the current timed drainage mode is not executed, and the timed drainage is performed again only after the next timed drainage is triggered.
[0075] Understandably, in traditional control logic, timed drainage might begin immediately after the float has finished draining. Since there are four float closing opportunities before the alarm, if timed drainage begins immediately after any of the first three float draining events, the drainage logic differs from the above steps. This time, the interruption occurs during the float closing drainage detection, and timed drainage begins precisely after the float's interruption. This can be categorized as timed drainage after float closing. If this happens after draining three times and then performing timed drainage again, it poses a risk of water overflow and can also cause the drain pump to run dry. Since the water in the drain box is almost completely drained immediately after the float closing drainage, performing timed drainage immediately would result in the drain pump working but no water being pumped up. If this occurs when the dryer is stationary, it can easily generate significant noise, affecting the user experience. To avoid this situation, if timed drainage is detected within a certain period after the float closing drainage, the current timed drainage will not occur; drainage will wait until the next timed drainage event.
[0076] In summary, by prohibiting the triggering of float-triggered drainage during and for a period after the scheduled drainage period ends, and canceling the scheduled drainage if it is encountered during the float-closed drainage period, and by setting the priority of the two drainage modes, the float-triggered drainage mode is executed first when both drainage modes are detected at the same time. This not only solves the problem of water overflow, but also prevents the drainage pump from running dry, avoids interrupting the float drainage logic, provides timely alarms, extends the service life of the drainage pump, reduces noise, and improves the user experience.
[0077] The control method for a clothes dryer provided in this application includes controlling a drain pump to execute a timed drainage mode in response to reaching a first preset condition; and controlling the drain pump to execute a float-triggered drainage mode in response to reaching a second preset condition; wherein, during the execution of the timed drainage mode, the drain pump is controlled to pause the execution of the float-triggered drainage mode. By controlling the drain pump to pause the judgment and execution of the float-triggered drainage mode when it is performing timed drainage, the frequent starting of the drain pump due to the float closing during the timed drainage period is avoided, thus preventing excessive continuous drainage and overflow, and extending the service life of the clothes dryer.
[0078] In one alternative implementation, the control method may include: acquiring the dryer's operating parameters and adjusting the priority of the timed drainage mode and the float-triggered drainage mode based on the operating parameters.
[0079] For example, the dryer automatically selects the drainage mode priority based on current usage parameters (such as ambient humidity, clothing type, and load). For instance, in high humidity environments or with heavy loads, the float-triggered drainage mode is prioritized to increase the drainage frequency; in low humidity environments or with light loads, the timed drainage mode is mainly relied upon to save energy; in mixed mode, the system can dynamically determine the float closing frequency, and if it exceeds a threshold, it automatically switches to the float-priority mode.
[0080] In one optional implementation, the dryer can dynamically adjust drainage parameters based on historical usage data. For example, the timed drainage interval can be automatically shortened or extended based on the historical float trigger frequency; the float closing determination time (e.g., 10 seconds) can be dynamically adjusted based on the working status of the drainage pump or the water tank capacity.
[0081] In an optional implementation, the control method may include, during the execution of a timed drainage mode or a float-triggered drainage mode, controlling the drainage pump to stop working and sending an alarm message if idling of the drainage pump is detected.
[0082] Specifically, whether a drain pump is running dry can be determined by detecting its current or speed. Once the drain pump has been running dry, it should be immediately stopped to prevent the motor from overheating and burning out, thus extending its service life and saving energy.
[0083] Secondly, embodiments of this application also provide a control device for a clothes dryer, the clothes dryer including a drying drum and a drain pump connected to the drying drum, see reference. Figure 3 As shown, the control device includes:
[0084] The drainage module 301 is used to control the drainage pump to execute a timed drainage mode in response to the achievement of a first preset condition; and to control the drainage pump to execute a float-triggered drainage mode in response to the achievement of a second preset condition; wherein, during the execution of the float-triggered drainage mode, the drainage pump is controlled to pause the execution of the timed drainage mode.
[0085] The control device for the dryer in this embodiment can be applied to a dryer and execute the control method for the dryer described above, so as to avoid overflow caused by excessive continuous drainage, prevent the drain pump from running dry, extend its service life, and provide timely alarm.
[0086] Thirdly, embodiments of this application provide a clothes dryer, including: a drying drum; a drain pump connected to the drying drum; and a controller electrically connected to the drain pump, configured to execute the control method of the clothes dryer described above.
[0087] Figure 4 An example of a schematic diagram of the physical structure of a controller is shown, such as... Figure 4 As shown, the controller may include a processor 401, a communication interface 402, a memory 403, and a communication bus 404.

The processor 401 can call logical instructions stored in the memory 403 to execute the steps of the dryer's control method.
[0088] Furthermore, the logical instructions in the aforementioned memory 403 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of this application can be embodied in the form of a software product.

The aforementioned storage medium includes various media capable of storing program code, such as a USB flash drive, a portable hard drive, a read-only memory 403 (ROM), a random access memory 403 (RAM), a magnetic disk, or an optical disk.
