[0049] In the related technology, there are many drainage logics for dryers. Currently, float alarms often occur, leading to customer complaints. Since a small pressure is generated between the condenser and the rotating drum, the water in the water box is sucked back into the air duct. After the dryer stops running, the water in the air duct will flow back into the water box. The water level in the water box is too high, causing the water level switch to close, which will cause the dryer to alarm for drainage when it is not drying. In order to solve this problem, the dryer usually continues to drain water when it stops. Although this solves the alarm problem, it will cause a loud noise problem. If the dryer continues to drain water after it stops running, it will generate noise, which can easily cause customers to misunderstand.

[0050] The present application provides a clothes dryer and a control method, a control device and a storage medium thereof to solve the problem of high noise during the operation of the existing clothes dryer. Figure 1-6 Provide explanation.

[0051] According to one embodiment of the present application, referring to Figure 1 and Figure 4 As shown, the control method of the clothes dryer includes:

[0052] S101: Acquire first state information of a motor.

[0053] Exemplarily, the motor in this embodiment is used to drive the drying drum of the dryer to rotate. The first state information of the motor can be obtained by a sensor connected to the motor. The sensor can be a current sensor, a speed sensor, etc., and the current state of the motor can be accurately judged by detecting parameters such as the motor current, speed or controller state feedback.

[0054] Specifically, the first state information of the motor may include an operating state or a non-operating state (such as pause, standby, shutdown, etc.). For example, when the system detects that the motor is rotating, it is judged that the motor is in an operating state. At this time, the motor drives the drying drum to rotate to dry the clothes in the drying drum. When the system detects that the motor stops rotating, it is judged that the motor is in a non-operating state. At this time, the drying drum stops rotating and the dryer stops running.

[0055] S102: When the first status information indicates that the motor is in a non-operating state, turning off the alarm function and the drainage function of the dryer.

[0056] When the dryer is paused or stopped during operation and the motor stops, when the pressure in the air duct is the same as that outside, the water remaining in the air duct will flow into the water box. If the water level is too high, the water level switch will be closed. If the drain pump continues to drain water at this time, the sound of the drain pump working will be produced. Sometimes, abnormal sounds will be emitted due to insufficient water drainage, resulting in loud noise, and users will mistakenly believe that the dryer has malfunctioned.

[0057] When it is detected that the motor is not in operation, the alarm function is turned off to avoid false alarms or unnecessary alarm sounds, reducing customer misunderstandings. At the same time, the drainage function is turned off when the motor is not in operation to prevent water from flowing back into the air duct after the dryer stops running, causing the water level switch to close and triggering the drain pump to drain water, thereby avoiding loud noise and improving the user experience.

[0058] S103: When the first status information indicates that the motor is in a running state, the alarm function and the drainage function are turned on.

[0059] By turning on the alarm and drainage functions only when the motor is running, the rotation sound of the motor itself will exist as background noise when the motor is running. Since the noise of the motor is usually louder than the noise of the drain pump, the sound produced by the drain pump when working will often be masked by the noise of the motor. At this time, the dryer is in working condition, so even if there is a drainage sound, it is normal and users will not regard it as abnormal noise, thus avoiding customers from mistakenly thinking that the dryer is faulty.

[0060] In an alternative embodiment, reference Figure 2 As shown, after the alarm function and the drainage function are turned on, the method further includes:

[0061] S201: Acquire second state information of the water level switch;

[0062] S202: When the second state information indicates that the water level switch is in a closed state, executing the drainage step according to a preset number of times to control the drainage pump to drain water;

[0063] S203: When the second state information indicates that the water level switch is in the disconnected state, the drainage pump is controlled to stop drainage.

[0064] In this embodiment, after the motor is in operation, the clothes dryer turns on the drainage function and the alarm function. At this time, the system further detects the state of the water level switch to determine the specific operation of the drainage pump.

[0065] The water level switch may contain a float, contacts or other sensors to detect water level changes. The system determines the state of the water level switch by reading the sensor signal. Based on the read signal, the system determines whether the water level switch is in a closed state (water level is higher than the threshold) or an open state (water level is lower than the threshold).

[0066] When the water level switch is in the closed state, it means that the water level in the water box has reached or exceeded the preset drainage threshold, and the drainage pump needs to be controlled to drain water. Specifically, the system controls the drainage pump to drain water according to the preset number of times, wherein the preset number of times can be adjusted according to actual conditions to ensure that the water in the water box is fully drained while avoiding excessive drainage.

[0067] During the drainage process, the system can continuously monitor the status of the water level switch or the water level change in the water box to evaluate the drainage effect. When the water level switch is in the off state, it means that the water level in the water box is lower than the preset drainage threshold. At this time, no drainage operation is required. The system immediately sends a signal to the drainage pump to instruct it to stop working, so as to avoid the drainage pump continuing to run when it is not needed, thereby saving energy and reducing noise.

[0068] In an alternative embodiment, reference Figure 3 As shown, the drainage step includes:

[0069] S301: Controlling the drainage pump to drain water for a first preset time;

[0070] S302: When it is detected that the water level switch is still in the closed state, controlling the drainage pump to drain water for a second preset time;

[0071] S303: When it is detected that the water level switch is in the disconnected state, the drainage pump is turned off.

[0072] In this embodiment, when the system detects that the water level switch is in a closed state, it means that the water level in the water box has reached the preset drainage threshold and the drainage pump needs to be started for drainage. At this time, the system first controls the drainage pump to work for a fixed time period, that is, the first preset time, to quickly reduce the water level in the water box and reduce the risk of overflow caused by excessively high water levels. The first preset time period can be pre-set according to factors such as the design of the dryer, the capacity of the water box, and the drainage capacity of the drainage pump.

[0073] After the first preset time of drainage, the state of the water level switch is checked again. If the water level switch is still in the closed state, it means that although the water level in the water box has dropped, it has not dropped below the preset low water level threshold. At this time, the system continues to control the drainage pump to work for the second preset time to further reduce the water level in the water box to ensure that the water is fully discharged.

[0074] If the system detects that the water level switch has changed from a closed state to an open state after the second preset time has passed, it means that the water level in the water box has dropped below the preset low water level threshold and there is no need to continue draining. At this time, the system immediately sends a signal to the drain pump to instruct it to stop working.

[0075] If after the second preset time, the system detects that the water level switch is still in the closed state, the above-mentioned drainage steps will continue to be executed to drain the water until the water level switch is detected to be in the open state, or the number of times the drainage steps have been executed has reached the preset number.

[0076] In an optional embodiment, after the drainage step is executed for a preset number of times to control the drainage pump to drain water, the method further includes: sending a warning message when it is detected that the water level switch is still in a closed state.

[0077] In this embodiment, after completing the preset number of drainage steps, if it is detected that the water level switch is still in the closed state, it means that the dryer has a drainage failure, which may be caused by a blockage in the water box or the drainage pipe. At this time, the dryer can send a warning message to remind the user in time.

[0078] In some embodiments of the present application, before controlling the drainage pump to drain water for a first preset time, the method further includes:

[0079] The closing time of the water level switch in the closed state is obtained; after the closing time reaches the preset time, the step of controlling the drainage pump to drain water for the first preset time is executed.

[0080] In this embodiment, drainage is not performed until the water level switch has been closed continuously for a preset time. This can effectively avoid energy waste and noise problems caused by short-term fluctuations or misjudgments of the water level. By ensuring that the water level is indeed higher than a certain level for a period of time, the accuracy and efficiency of drainage control are improved.

[0081] If the closing time reaches the preset time and the water level switch is still in the closed state, the system will execute the step of controlling the drainage pump to drain water. At this time, it can be considered that the water surface is relatively stable and it is reasonable to drain water. This method can ensure that the drainage pump is only started when the water level really needs to be drained, thereby avoiding frequent drainage and energy waste caused by short-term water level fluctuations; at the same time, it also reduces unnecessary noise generation and improves the overall performance and user experience of the equipment.

[0082] In some embodiments of the present application, when it is detected that the closing time is less than the preset time, the drainage pump is controlled to maintain the current operating state. For example, when it is detected that the water level switch is closed, but the closing time is less than the preset time, it means that the water level has dropped below the preset water level threshold, or the water level fluctuates greatly at this time. At this time, the drainage pump is controlled to maintain the current state, for example, the drainage pump still does not start drainage, until the water level stabilizes to determine whether drainage is needed, thereby ensuring the accuracy and efficiency of drainage control.

[0083] Exemplarily, the preset time may be 2s, 3s, or 4s, etc. For example, when the water level switch is detected to be closed, drainage may begin 3s later.

[0084] In some embodiments of the present application, the preset number of times is two; and / or, the first preset time is equal to the second preset time.

[0085] Exemplarily, when the motor is started, the system starts to monitor the state of the water level switch. If the water level switch is detected to be closed for 3 consecutive seconds after the motor is started, the drainage step is performed. If the water level switch signal is disconnected within 3 seconds, the drainage step is not performed and the water level continues to be monitored.

[0086] The drainage steps include: the first stage of drainage is pumping water for 30 seconds. After 30 seconds of pumping, if it is detected that the water level switch signal is disconnected, the drainage is stopped immediately. If the water level switch signal is still closed after 30 seconds, the second stage of drainage is continued. The second stage continues to drain for 30 seconds. At this time, the total drainage time reaches 60 seconds. After 60 seconds of pumping, similarly, if it is detected that the water level switch signal is disconnected, the drainage is stopped immediately. If the water level switch signal is still closed after 60 seconds, the above drainage steps are repeated to continue drainage.

[0087] If the system continues to detect that the water level switch is closed after a maximum of two drainage attempts (when the cumulative drainage time reaches 120 seconds), it is determined that the dryer has a drainage failure and the dryer sends a warning message to remind the user.

[0088] After a drainage fault is reported, the system requires manual intervention to solve the problem, such as clearing the blockage, checking the water level switch, etc. Before the fault is resolved, the system can remain in shutdown state or enter safe mode.

[0089] The control method of the clothes dryer provided in the embodiment of the present application includes obtaining the first state information of the motor; when the first state information indicates that the motor is in a non-operating state, turning off the alarm function and the drainage function of the clothes dryer; when the first state information indicates that the motor is in an operating state, turning on the alarm function and the drainage function. The clothes dryer is drained and alarmed normally only when the motor is running, and the alarm function and the drainage function are shielded when the motor is not running, thereby reducing unnecessary noise and customer misunderstanding, effectively avoiding the problem of large noise caused by the drainage pump still draining after the clothes dryer stops running, and also avoiding the alarm phenomenon after the water level switch is closed due to the backflow of water in the air duct after the clothes dryer stops running.

[0090] Second, reference Figure 5 As shown, the embodiment of the present application also provides a control device for a clothes dryer, comprising:

[0091] An acquisition module 501 is used to acquire first state information of the motor;

[0092] A closing module 502, configured to close an alarm function and a drainage function of the clothes dryer when the first state information indicates that the motor is in a non-operating state;

[0093] The start module 503 is used to start the alarm function and the drainage function when the first state information indicates that the motor is in the running state.

[0094] All of the above technical solutions can be arbitrarily combined to form optional embodiments of the present application, which will not be described in detail here.

[0095] The control device for a clothes dryer provided in the embodiment of the present application is applied to the clothes dryer. During the use of the clothes dryer, the opening and closing of the alarm function and the drainage function are controlled based on the state of the motor. Normal drainage and alarm are performed only when the motor is running, and the alarm function and the drainage function are shielded when the motor is not running, thereby reducing unnecessary noise and customer misunderstanding, and effectively avoiding the problem of loud noise caused by the drainage pump still draining after the dryer stops running, and also avoiding the alarm phenomenon after the water level switch is closed due to the backflow of water in the air duct after the dryer stops running.

[0096] On the third aspect, an embodiment of the present application also provides a dryer, including a drying drum, a motor, a water box, a drain pump, an alarm and a controller, wherein the motor is electrically connected to the drying drum and is used to drive the drying drum to rotate; the water box is used to collect condensed water during the drying process of the drying drum; the drain pump is used to discharge water in the water box; the alarm is used to send warning information; the controller is electrically connected to the motor, the drain pump and the alarm to execute the control method of the dryer of the above embodiment.

[0097] The dryer may be a dryer having only a drying function, or may be a washer-dryer having both washing and drying functions, which is not specifically limited in this embodiment.

[0098] Exemplarily, a hot air circulation system is designed inside the drying drum, which is used to heat and blow hot air onto the clothes to remove moisture from the clothes and achieve the drying function. The rotation of the drying drum not only helps the clothes to be heated evenly, but also accelerates the evaporation of moisture by tumbling the clothes. The motor is connected to the drying drum and is the power source for driving the drying drum to rotate. During the drying process, the moisture in the clothes is absorbed by the hot air to form condensed water. When the condensed water in the water box accumulates to a certain amount, the drainage pump will be started to extract the water from the water box and discharge it outside the dryer. When the dryer has an abnormal situation such as a drainage failure, the alarm will issue a warning message to remind the user to check and deal with it in time, which helps to prevent potential safety hazards and protect the dryer from damage. The controller is used to execute the control method of the dryer of the above embodiment to reduce the noise generated during the operation of the dryer and improve the user's experience.

[0099] In an optional embodiment, the volume of the water box is designed to ensure that the water box can store a certain amount of water. This volume should be able to accommodate all the water that flows into the air duct after the motor is paused, while leaving enough margin to prevent overflow. When the water in the water box and the buoy are closed at a critical value, the limited space in the air duct is filled with water, so that after the motor is paused, all the water in the air duct flows into the water box and the water will not overflow. Even if the water is not drained after the motor stops running, the water box will not overflow.

[0100] Figure 6 An example of a physical structure diagram of an electronic device is shown in FIG. Figure 6 As shown, the electronic device may include: a processor 601 (processor), a communication interface 602 (Communications Interface), a memory 603 (memory) and a bus 604, wherein the processor 601, the communication interface 602, and the memory 603 communicate with each other through the communication bus 604. The processor 601 may call the logic instructions in the memory 603 to execute the steps of the control method of the clothes dryer.

[0101] In addition, the logic instructions in the above-mentioned memory 603 can be implemented in the form of a software functional unit and can be stored in a computer-readable storage medium when it is sold or used as an independent product. Based on such an understanding, the technical solution of the present application can be embodied in the form of a software product, which is stored in a storage medium, including a number of instructions to enable a computer device (which can be a personal computer, a server, or a network device, etc.) to perform all or part of the steps of the various embodiments of the present application. The aforementioned storage medium includes: a U disk, a mobile hard disk, a read-only memory 603 (ROM, Read-Only Memory), a random access memory 603 (RAM, Random Access Memory), a disk or an optical disk, and other media that can store program codes.

When the program instructions are executed by a computer, the computer can execute the control method of the dryer provided by the above-mentioned method embodiments.

[0103] On the other hand, an embodiment of the present application further provides a computer-readable storage medium having a computer program stored thereon, which is implemented when the processor 601 executes the control method of the dryer provided in the above embodiments.

Based on this understanding, the above technical solution is essentially or the part that contributes to the prior art can be embodied in the form of a software product, and the computer software product can be stored in a computer-readable storage medium, such as ROM / RAM, a disk, an optical disk, etc., including a number of instructions for a computer device (which can be a personal computer, a server, or a network device, etc.) to execute the methods of each embodiment or some parts of the embodiment.
