[0043] The embodiments of the present application provide a clothes dryer, a control method, a control device and a storage medium, to solve the problem that the existing clothes dryer cannot timely alarm when the water storage box is full. The following will be described in conjunction with the drawings.

[0044] The control method of the clothes dryer provided in the embodiments of the present application, please refer to Figure 2The clothes dryer comprises a water collecting box 1, a water storage box 2 and a water pump 5, the water collecting box 1 is used for collecting condensed water, the water pump 5 is used for draining water in the water collecting box 1 to the water storage box 2 through a drain pipe 3, when the water storage box 2 is full, water is returned to the water collecting box 1 through a return pipe 4, a water level detection device 6 is arranged in the water collecting box 1, please refer to Figure 1 The method comprises the following steps:

[0045] Step S101: control the water pump 5 to start;

[0046] Step S102: after a first preset time, control the water pump 5 to stop, and obtain a first water level drop parameter of the water collecting box 1 within the first preset time;

[0047] Step S103: if the first water level drop parameter is less than a first preset parameter, control the water pump 5 to start;

[0048] Step S104: after a second preset time, control the water pump 5 to stop, and obtain a second water level drop parameter of the water collecting box 1 within the second preset time;

[0049] Step S105: if the second water level drop parameter is less than a second preset parameter, issue a water full alarm of the water storage box 2; wherein the second preset time is less than the first preset time, and the second preset parameter is less than the first preset parameter.

[0050] The control method of the clothes dryer provided in the embodiments of the present application includes the following steps: after the water collecting box 1 is drained by the drain pump 5 for a first preset time, the drain pump 5 is turned off, and a first water level drop parameter of the water collecting box 1 in the first preset time is analyzed; if the first water level drop parameter is less than a first preset parameter, it indicates that the water amount dropped in the water collecting box 1 is less than the water amount drained by the drain pump 5 in the first preset time, which may be caused by continuous draining of the drum into the water collecting box 1, or the water storage box 2 is full and the water flows back to the water collecting box 1 through the backwater pipe 4, or the drain pipe 3 is blocked, causing slow water drop in the water collecting box 1; to further determine whether the water storage box 2 is full, the drain pump 5 is turned on again for a second preset time; since the second preset time is short, the interference caused by the condensed water generated by the drying of the clothes dryer to the water collecting box 1 is reduced, and whether the water amount dropped in the water collecting box 1 in the second preset time is less than a second preset parameter is analyzed; if the second water level drop parameter is less than the second preset parameter, it indicates that the water level in the water collecting box 1 drops little in the second preset time, and it is determined that the water drained from the water collecting box 1 to the water storage box 2 basically flows back to the water collecting box 1 through the backwater pipe 4, causing the water collecting box 1 to fail to drain, so it is determined that the water storage box 2 is full, and a full water alarm is issued to prompt the user to clean the water storage box 2 in time, so that the alarm can be issued in time when the water storage box 2 is full, and the operation of the clothes dryer is not affected. In some examples, the second preset parameter is only slightly greater than zero, so as to be compatible with the flow loss of the water flowing from the drain pipe 3 to the water storage box 2, the backwater pipe 4, and the hysteresis of the water flowing back to the water collecting box 1 from the backwater pipe 4.

[0051] As a specific embodiment, the first water level drop parameter of the water collecting box 1 in the first preset time can be the difference between the first water level frequency of the water collecting box 1 before the first preset time starts to be counted and the second water level frequency of the water collecting box 1 after the first preset time.

[0052] Optionally, steps S101 to S104 can be executed three times in a cycle, and the number of times that the second water level drop parameter is less than the second preset parameter is accumulated, and the full water alarm of the water storage box 2 is issued according to the number of times that the second water level drop parameter is less than the second preset parameter. For example, when the number of times that the second water level drop parameter is less than the second preset parameter is greater than or equal to two, the full water alarm of the water storage box 2 is issued. This can further improve the accuracy of the detection result.

[0053] Optionally, after the second water level drop parameter of the water collecting box 1 in the second preset time is obtained, the method further includes: if the second water level drop parameter is greater than or equal to the second preset parameter and less than a third preset parameter, issuing a drain pipe 3 blockage alarm; wherein the third preset parameter is greater than the second preset parameter and less than the first preset parameter.

[0054] When the second water level drop parameter is greater than or equal to the second preset parameter and less than the third preset parameter, it indicates that while the water level in the water collection box 1 has dropped to a certain extent within the second preset time period, it does not match the theoretical discharge capacity of the drain pump 5 and is less than the theoretical discharge capacity of the drain pump 5 during that time period. Therefore, it can be concluded that the drain pipe 3 is clogged, preventing all the water pumped by the drain pump 5 from entering the water storage box 2. This triggers a drain pipe 3 blockage alarm, prompting the user to promptly clean the drain pipe 3 to avoid affecting the operation of the clothes dryer. The above detection method enables intelligent detection of drain pipe 3 blockage without the need for regular disassembly of the drain pipe 3 for inspection, significantly reducing the difficulty of drain pipe 3 maintenance, saving maintenance time and process, and achieving low cost without the need to install additional detection components. In some examples, the third preset parameter can be slightly less than the theoretical discharge capacity of the drain pump 5 within the second preset time period to accommodate flow losses after water flows from the drain pipe 3 through the water storage box 2 and return pipe 4, as well as the hysteresis of water flowing back from the return pipe 4 to the water collection box 1.

[0055] Optionally, controlling the drain pump 5 to start includes: obtaining the water level of the water collecting box 1 in response to the drying instruction; and when the water level is higher than a first preset water level, controlling the drain pump 5 to start. By setting the start condition of the drain pump 5, frequent start of the drain pump 5 is prevented.

[0056] Optionally, after obtaining the second water level drop parameter of the water collecting box 1 within the second preset time period, the method also includes: if the second water level drop parameter is greater than or equal to the third preset parameter, controlling the drainage pump 5 to turn on until the water level of the water collecting box 1 is lower than the second preset water level; the second preset water level is lower than the first preset water level.

[0057] If the second water level drop parameter is greater than or equal to the third preset parameter, it indicates that the water level drop value of the water collecting box 1 within the second preset time period is basically consistent with the theoretical drainage volume of the drain pump 5 within the second preset time period, so the situation that the water level of the water collecting box 1 drops slowly due to blockage of the drain pipe 3 and the water level of the water collecting box 1 almost does not drop due to the water storage box 2 being full is ruled out. This indicates that within the first preset time period, the first water level drop parameter of the water collecting box 1 is less than the first preset parameter. This is because the cylinder discharges a lot of condensed water into the water collecting box 1 within the first preset time period, and the drain pipe 3 and the water storage box 2 are both normal. Therefore, the drain pump 5 is further turned on to lower the water level in the water collecting box 1 to below the second preset water level, so that the water level in the water collecting box 1 is lower, to prevent the water level in the water collecting box 1 from rising too quickly and causing the drain pump 5 to be frequently turned on.

[0058] Optionally, after the water storage box 2 is issued with a full water alarm, the method further comprises: controlling the clothes dryer to stop a drying process.

[0059] That is, after the water storage box 2 is full, to avoid the continued discharge of condensed water from the cylinder to the water collection box 1, causing the water level in the water collection box 1 to continue to rise and thus overflow and cause other components to be flooded, the control dryer stops the drying program and stops the operation of the dryer, preventing the cylinder from further discharging condensed water to the water collection box 1, and preventing the water collection box 1 or the water storage box 2 from overflowing externally.

[0060] Optionally, after the drain pipe 3 blockage alarm is issued, the method further includes: controlling the dryer to stop the drying program. As for the control of the dryer to stop the drying program after the water storage box 2 full alarm is issued, it will not be repeated here.

[0061] Optionally, after the dryer is controlled to stop the drying program, the method further includes: in response to a user inputted continue draining instruction, controlling the drain pump 5 to be turned on, and controlling the dryer to continue to execute the drying program; if the water level in the water collection box 1 is lower than the second preset water level, controlling the drain pump 5 to be turned off.

[0062] That is, after the user manually pours out the water in the water storage box 2, the user can press the continue operation button on the dryer, so that the dryer can continue to execute the drying program and turn on the drain pump 5 to normally drain water until the water level in the water collection box 1 reaches the off condition of the drain pump 5, i.e., the water level in the water collection box 1 is lower than the second preset water level, and then the drain pump 5 is turned off.

[0063] Optionally, after the drain pump 5 is turned off, before the second water level drop parameter of the water collection box 1 in the second preset time period is obtained, the method further includes: waiting for a third preset time period; wherein the third preset time period is less than the second preset time period.

[0064] That is, after the drain pump 5 is turned off, a third preset time period can be waited for, and then the second water level drop parameter of the water collection box 1 in the second preset time period is obtained, to reserve a backflow time for the water in the backwater pipe 4 to backflow to the water collection box 1, and to further improve the accuracy of obtaining the second water level drop parameter. The third preset time period can be relatively short, such as 3 seconds, 5 seconds, or 10 seconds, etc.

[0065] Optionally, after the drain pump 5 is turned off, before the first water level drop parameter of the water collection box 1 in the first preset time period is obtained, the method further includes: waiting for a third preset time period; wherein the third preset time period is less than the second preset time period.

[0066] Optionally, issuing the water storage box 2 full alarm includes: controlling the alarm device of the dryer to issue the water full alarm; or, controlling the dryer to issue the water full alarm to the mobile device of the user. Controlling the alarm device of the dryer to issue the water full alarm can include a sound signal alarm (such as a buzzer ringing), a light signal alarm (such as a warning light flashing), or a vibration alarm (a vibration module vibrating), etc. Controlling the dryer to issue the water full alarm to the mobile device of the user can include sending an alarm message to the user's mobile phone or tablet or television.
