In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0050] In the related art, a clothes dryer is usually provided with a lower water box (first water box) and an upper water box (second water box). The first water box is arranged at the bottom of the clothes dryer to collect moisture from the clothes during the rotation and heating process. The first water box is usually non-detachable, and the second water box is located above the first water box, that is, the second water box is usually detachably arranged on the top of the dryer. The water in the first water box is pumped into the second water box by a drainage pump, and when the water in the second water box reaches a certain amount, the excess water can overflow into the first water box below through a pipe. If the water level in the first water box is still high after the drainage pump is started to drain, the dryer will alarm to prompt the user to pour out the water in the second water box.

[0051] In existing dryers, there is a phenomenon that the alarm is not triggered after the second water box is full of water, causing the water in the second water box to overflow to the front control panel of the dryer. Part of the overflowed water directly evaporates inside the dryer, causing various components inside the dryer to come into contact with water vapor, affecting the safety performance of the dryer. After research, it was found that the reason why the dryer cannot alarm normally is that the drainage speed of the drainage pump is greater than the speed of drainage from the second water box to the first water box, and the detection time of the water level sensor is less than the time of the drainage pump, resulting in the failure of normal alarm. The water accumulated in the second water box becomes more and more, and eventually leaks out from the gap at the bottom of the water box, seriously affecting the user experience.

[0052] 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 1-5 Provide explanation.

[0053] According to one embodiment of the present application, referring to Figure 1 As shown, the control method of the clothes dryer includes:

[0054] S101: Obtaining a first current water level of a first water box;

[0055] For example, the water level in the first water box may be detected by a water level sensor such as a float switch, and the water level sensor transmits the water level information to a control unit of the clothes dryer for further processing.

[0056] S102: Determine that a first current water level meets a preset condition, and control a drainage pump to drain water for a first drainage time;

[0057] When it is detected that the first current water level of the first water box meets the preset condition, the drainage pump is started to pump the water in the first water box to the second water box to lower the water level in the first water box and prevent the water in the first water box from overflowing. In this process, the system will set a first drainage time and control the drainage pump to stop after the first drainage time to ensure that enough water in the first water box is discharged to the second water box.

[0058] Exemplarily, the first drainage time is set to 20s-25s. For example, the first drainage time can be 20s, 21s, 22s, 23s, 24s or 25s. The purpose of setting this drainage time range is to avoid the water in the second water box from overflowing from the front control panel due to the water pumping volume being too large and not being able to be drained to the first water box in time.

[0059] In an optional embodiment, determining that the first current water level satisfies the preset condition includes: when the first current water level is greater than or equal to the preset water level and the duration is greater than a first preset time, determining that the first current water level satisfies the preset condition.

[0060] It is understandable that the first current water level of the first water box may temporarily exceed the preset water level due to reasons such as vibration of the clothes dryer. By setting a continuous first preset time, it is possible to avoid false triggering of the drain pump due to short-term water level fluctuations, reduce the frequent start-up of the drain pump, improve drainage efficiency, extend the life of the equipment, and reduce the noise caused by frequent drainage. Optionally, the first preset time can be 5s, and the timing starts when the current water level of the first water box is greater than or equal to the preset water level. When the first current water level of the first water box is greater than or equal to the preset water level for 5 consecutive seconds, it is determined that the first current water level meets the preset condition, indicating that the water level in the first water box is high, and the drain pump needs to be turned on to drain the first water box.

[0061] S103: After the drainage is completed and the first interval time has elapsed, the second current water level of the first water box is obtained again;

[0062] After the drain pump stops working, the dryer will wait for a set first interval time, and then detect the second current water level of the first water box again, so as to ensure that after the water in the second water box is full, the excess water can be discharged into the first water box through the corresponding pipeline, so that the water levels in the first water box and the second water box are stable before detection, thereby ensuring the accuracy of water level detection and avoiding the situation that when the detection starts immediately after drainage, the excess water has not yet flowed back into the first water box, resulting in a lower water level in the first water box monitored by the water level sensor, and the alarm cannot be triggered normally even if the water in the two water boxes is full.

[0063] Exemplarily, the first interval time is set to 15s-20s, for example, the first interval time is 15s, 16s, 17s, 18s, 19s or 20s. This interval time range is set to ensure that after the second water box is full, excess water can be fully drained into the first water box, so that the next time the water level in the first water box meets the preset conditions, the next round of drainage can be started.

[0064] It can be understood that the first current water level is the water level height of the first water box in the initial state, and the second current water level is the water level height of the first water box after the drainage pump drains and stabilizes.

[0065] S104: Based on the second current water level, control the clothes dryer to drain water or alarm.

[0066] In an optional embodiment, controlling the dryer to drain or alarm includes: controlling the dryer to continue draining when the second current water level still meets the preset conditions; determining the drainage cycle of the dryer; and controlling the dryer to alarm after a preset number of drainage cycles when the second front water level still meets the preset conditions.

[0067] In this embodiment, after drainage, if it is monitored that the second current water level of the first water box still meets the preset conditions, the dryer is controlled to continue draining according to the above steps S102 and S103, and the number of drainage cycles is calculated. After executing the above drainage steps for a preset number of times, if it is monitored that the second current water level still meets the preset conditions (for example, the second current water level is greater than or equal to the preset water level for a duration of 5s), it means that the water in the second water box in the dryer is full, and the alarm system of the dryer is triggered to alarm.

[0068] Optionally, the preset number of cycles is three times, that is, if the second current water level of the first water box is still monitored to meet the preset condition after the first water box is drained three times, the dryer is controlled to stop working, the water tank icon in the display panel of the dryer is controlled to flash to remind the user, and the digital tube is controlled to display the alarm code "FUL" to remind the user to pour out the water in the second water box.

[0069] In an optional embodiment, the method for determining the drainage cycle of a dryer includes: initializing the drainage cycle; adding 1 to the count value of the drainage cycle after each control of the drainage pump to drain water; and clearing the count value of the drainage cycle when it is detected that the second current water level is lower than the preset water level and the duration is greater than the second preset time.

[0070] Optionally, before the dryer starts running or the drainage process begins, the value of the drainage cycle is initialized to 0, and each time the drain pump is controlled to drain, the count value of the drainage cycle is increased by 1, and the number of drainage times is recorded. After the drainage is completed, it is monitored that the second current water level of the first water box is lower than the preset water level and the duration exceeds the second preset time (for example, 5s). It means that the drainage system of the dryer is working normally, and the water below the water box has been effectively drained to the second water box. At this time, the count value of the drainage cycle is cleared, the counting cycle is reset, and the drainage cycle is continued to be calculated after the drain pump is triggered to drain next time.

[0071] In an optional embodiment, after the dryer alarm is detected and the water in the second water box is poured out, before obtaining the current water level of the first water box, the method further includes: controlling the drain pump to drain water for a first drainage time.

[0072] In this embodiment, after the dryer triggers the drainage alarm, the user is required to manually pour out the water in the second water box to prevent the water in the second water box from overflowing onto the front control panel of the dryer. The dryer is then restarted and the drainage pump is turned on for the first drainage time (e.g., 20s) to pump the water in the first water box into the second water box. The drainage logic is then continued in a cycle according to steps S101-S104 above until the second current water level in the first water box is below the preset water level.

[0073] Specifically, whether the user pours out the water in the second water box can be detected by means of a visual sensor or the like.

[0074] In an alternative embodiment, reference Figure 2 As shown, the control method of the clothes dryer further includes:

[0075] S201: Obtaining the working stage of the dryer;

[0076] S202: When the working stage is a pause stage or an anti-wrinkle stage, control the drainage pump to turn off.

[0077] In this embodiment, when it is detected that the dryer is in the pause stage or the anti-wrinkle stage, the water level sensor does not detect the water level of the first water box. The dryer will not perform drying operations during the pause stage, and the anti-wrinkle stage is generally performed in the last stage after the drying cycle. In these two processes, the washing machine will not perform drying operations, and the water in the first water box will not overflow. Even if the second current water level of the first water box reaches the preset water level, it will not affect the drying effect of this time and the normal drying next time. When the dryer is restarted and ready to dry, it will perform drainage operations according to the above control logic. Even if all the water remaining in the air duct and the pipeline flows into the first water box, it will not affect the normal alarm logic of the dryer. Furthermore, turning off the drainage pump during the pause and anti-wrinkle stages can reduce the generation of noise and improve the user experience.

[0078] In a specific embodiment, reference Figure 3 As shown, the control method of the clothes dryer includes:

[0079] (1) The drainage algorithm logic is modularized so that other functions can more conveniently call the drainage logic. The drainage function is triggered only when drainage is needed. The condition for achieving the drainage logic is to detect the water level conduction for 5 consecutive seconds, start the pump for 20 seconds, and wait for 15 seconds. This is a drainage cycle, and the cycle count is set to 1. The purpose of designing the drainage for 20 seconds is to ensure that the water discharged to the second water box each time can just not overflow the front control panel. If the drainage is drained for a few more seconds, the water stored under the second water box may overflow. The purpose of designing the waiting time for 15 seconds is to allow the excess water in the second water box to flow to the first water box through the lower drainage, so that the water accumulation problem can be cleared in the next drainage, and the next drainage can start again.

[0080] (2) The logic of the first drainage can ensure that the water does not overflow or accumulate, preparing for the next cycle. The subsequent detection only needs to detect the drainage cycle. If the water level is disconnected for 5 consecutive seconds, the cycle count is reset to zero. If the water level is connected for 5 consecutive seconds, the cycle is carried out according to the cycle, and the drainage cycle count is increased by 1.

[0081] (3) After three consecutive drainage cycles, if the water level is still detected for 5 seconds, the entire water level detection time is greater than the total time of three drainages. In order to ensure that the alarm can be processed, avoid the situation where there is no detection logic when the alarm condition is reached. When the alarm condition is reached for 5 seconds for the fourth time, the whole machine stops working, the water tank icon on the display board flashes, and the digital tube displays the alarm code "FUL".

[0082] (4) To clear the alarm, the user needs to clean out the water in the second water box in time. After clearing the water in the second water box, restart the system and let the drain pump drain for 20 seconds. Then continue the above cycle drainage logic to execute the unfinished program.

[0083] The control method of the clothes dryer of this embodiment starts to detect the water level after the first interval time after drainage, ensuring that the water overflowing from the second water box can all flow into the first water box; the time for detecting the closing of the float switch is greater than the pumping time of the drainage pump, ensuring that the float switch is still detected after drainage, and when the water in the second water box is drained to the first water box, it is necessary to ensure that the speed of the drainage is greater than the pumping speed of the drainage pump, so that more water is drained into the first water box, and the user can be notified in time when the first water box is full, and the user does not have to worry about the risk of forgetting to dispose of the water in the water box in time. When the water flows to the first water box, it will not cause the water to flow out from the surface of the dryer, and then will not cause the water to evaporate into the inner barrel; improving the drainage problem of the water box from the algorithm level, there is no need to improve the structure of the water box (increase the capacity), which can save a lot of material costs.

[0084] In a second aspect, an embodiment of the present application further provides a control device for a clothes dryer, the clothes dryer comprising a first water box, a second water box and a drainage pump, the second water box being arranged above the first water box, the drainage pump being used to transport water from the first water box to the second water box, and water overflowing from the second water box being suitable for flowing back to the first water box, Figure 4 As shown, the control device of the clothes dryer includes:

[0085] A first acquisition module 401 is used to acquire a first current water level of a first water box;

[0086] The first control module 402 is used to determine that the first current water level meets the preset condition and control the drainage pump to drain water for a first drainage time;

[0087] The second acquisition module 403 is used to acquire the second current water level of the first water box again after the drainage is completed and the first interval time has elapsed;

[0088] The second control module 404 is used to control the clothes dryer to drain water or alarm based on the second current water level.

[0089] 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.

[0090] 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, by completing the drainage and then detecting the water level after a first interval, it can be ensured that the drainage speed of the second water box falling into the first water box is greater than the pumping speed of the drainage pump, and that the excess condensed water in the second water box can all overflow back into the first water box for detection, thereby avoiding the defect that the water level height is too low when the water level detection starts immediately after drainage and the normal alarm cannot be given.

[0091] In the third aspect, the embodiments of the present application also provide a dryer, including a drying drum, a first water box, a second water box, a drainage pump and a water level sensor, wherein the first water box is used to collect condensed water during the drying process of the drying drum, the second water box is arranged above the first water box, and the water overflowing from the second water box is suitable for flowing back to the first water box; the drainage pump is used to transport the water in the first water box to the second water box; the water level sensor is used to detect the current water level of the first water box; the controller is electrically connected to the water level sensor and the drainage pump, and is configured to execute the control method of the dryer of any of the above embodiments.

[0092] 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.
