Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0041] 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 heat pump clothes dryer is usually provided with a timing reminder to remind the user to clean the impurities in the lint collecting box, lacking real-time and intelligence, and the lint collecting box may be full, causing the heat pump clothes dryer to run inefficiently. The following will be described with reference to the drawings.

[0042] The control method of the clothes dryer provided by the embodiments of the present application, the clothes dryer includes a compressor and a lint box, please refer to Figure 1 , the method includes the following steps:

[0043] Step S101: control the compressor to start, and acquire the temperature rise data of the outlet of the lint box;

[0044] Step S102: if the temperature rise data of the outlet of the lint box is greater than a first preset value, control the compressor to stop;

[0045] Step S103: after a preset shutdown time, acquire the temperature drop data of the outlet of the lint box;

[0046] Step S104: if the temperature drop data of the outlet of the lint box is less than a second preset value, issue a cleaning reminder for the lint box.

[0047] The control method of the clothes dryer provided by the embodiments of the present application monitors the temperature rise of the lint filter outlet after the compressor is turned on to dry the load, and when the temperature rise data of the lint filter outlet is greater than a first preset value, it indicates that the lint filter may be blocked. To further rule out the possibility that the lint filter outlet temperature rise is caused by compressor failure, the compressor is turned off, and the temperature drop data of the lint filter outlet is obtained after a preset shutdown time. By detecting the temperature drop of the lint filter under the condition that the compressor is turned off, it is determined whether the lint filter is blocked. If the temperature drop data of the lint filter outlet is less than a second preset value, it indicates that the temperature drop of the lint filter is small within the preset shutdown time, and it can be determined that the lint filter is blocked, so that the air flow through the lint filter is slow, resulting in slow temperature drop of the lint filter outlet. Therefore, a prompt is sent to clean the lint filter, so that the user can clean the lint filter in time when the lint filter is blocked, avoiding affecting the normal operation of the clothes dryer. At the same time, this detection method does not need to set high-cost sensors, and realizes the real-time and intelligent detection of the lint filter with low equipment cost.

[0048] Optionally, after the compressor is controlled to be turned on, the method further comprises: obtaining temperature rise data of the compressor exhaust port; and if the temperature rise data of the compressor exhaust port is greater than a third preset value, the compressor is controlled to be turned off.

[0049] Since the blockage of the lint filter will cause the system circulating air volume to decrease, the heat exchange to be slower, and the temperature of the refrigerant sucked back by the compressor to be higher, the exhaust temperature will also be higher, causing the compressor to heat up faster. Therefore, by detecting the temperature of the compressor exhaust port, when the temperature rise data of the compressor exhaust port is greater than a third preset value, it indicates that the compressor temperature rise is abnormal, and there may be a situation of lint filter blockage. By detecting the temperature of the compressor exhaust port, an auxiliary detection mechanism for detecting the temperature of the lint filter outlet is set to prevent the temperature at the lint filter outlet from being inaccurate or abnormal and ignoring the situation of lint filter blockage, and to ensure the normal operation of the clothes dryer.

[0050] Optionally, the compressor is controlled to be turned on, including: determining the target running power of the compressor based on the load quality; and controlling the compressor to run at the target running power. The running power of the compressor is adjusted based on the quality of the load to be dried, so as to avoid waste of energy consumption and save use cost while meeting the drying function. It can be understood that the smaller the load quality is, the smaller the running power of the corresponding compressor is, and the greater the load quality is, the greater the running power of the corresponding compressor is.

[0051] Optionally, the temperature rising data of the lint filter outlet is obtained, including: obtaining a first temperature of the lint filter outlet; obtaining a second temperature of the lint filter outlet after a preset temperature rising time; calculating a ratio of the second temperature to the first temperature, and determining the ratio as the temperature rising data of the lint filter outlet. In some examples, the first preset value can be 1.5, that is, when the ratio of the second temperature of the lint filter outlet to the first temperature of the lint filter outlet is greater than 1.5, it indicates that the temperature rising at the lint filter outlet is abnormal, and the compressor is controlled to shut down to avoid interference of the compressor failure on the temperature rising detection of the lint filter.

[0052] Optionally, the temperature falling data of the lint filter outlet is obtained, including: obtaining a third temperature of the lint filter outlet; calculating a temperature difference between the third temperature and the second temperature, and determining the temperature difference as the temperature falling data of the lint filter outlet.

[0053] When the lint filter is not blocked normally, the system circulation air duct is unobstructed, and the temperature falling speed at the lint filter outlet is fast. It can be understood that the higher the blocking degree of the lint filter is, the slower the temperature falling speed at the lint filter outlet is. Therefore, by monitoring the temperature falling situation at the lint filter outlet after the compressor is shut down, the blocking situation of the lint filter is obtained, and interference of the compressor failure on the judgment of the blocking situation of the lint filter is avoided. When the temperature difference between the third temperature and the second temperature of the lint filter outlet is large, it indicates that the lint filter is unobstructed temporarily. When the temperature difference between the third temperature and the second temperature of the lint filter outlet is small, it indicates that the lint filter is blocked. In some examples, the second preset value can be 5℃.

[0054] Optionally, after the temperature falling data of the lint filter outlet is obtained, the method further includes: if the temperature falling data of the lint filter outlet is greater than or equal to the second preset value, controlling the compressor to start until the drying ends. If the temperature falling data of the lint filter outlet is greater than or equal to the second preset value, it indicates that the lint filter is not blocked, and therefore the drying operation can be continued.

[0055] Optionally, the temperature rising data of the compressor exhaust port is obtained, including: obtaining a fourth temperature of the compressor exhaust port; obtaining a fifth temperature of the compressor exhaust port after a preset temperature rising time; calculating a ratio of the fifth temperature to the fourth temperature, and determining the ratio as the temperature rising data of the compressor exhaust port. In some examples, the third preset value can be 2.5, that is, when the ratio of the fifth temperature of the compressor exhaust port to the fourth temperature is greater than 2.5, it indicates that the temperature rising at the compressor exhaust port is abnormal, and there can be a blocking situation of the lint filter, and then the compressor is controlled to shut down to further investigate the blocking situation of the lint filter.

[0056] Optionally, after obtaining the first temperature of the lint filter outlet, the method further comprises determining a preset temperature rising duration based on the load quality. It can be understood that the greater the load quality, the slower the temperature rising speed, and thus the longer the required temperature monitoring time. The smaller the load quality, the faster the temperature rising speed, and thus the shorter the required temperature monitoring time, so as to ensure more accurate monitoring results.

[0057] In some examples, the operating power of the compressor can include one gear and two gears. When the load quality is less than a preset quality, the operating power of the compressor is determined as the one gear, the preset temperature rising duration is 20 minutes, the first preset value is 2, and the third preset value is 3. When the load quality is greater than or equal to the preset quality, the operating power of the compressor is determined as the two gear, the preset temperature rising duration is 25 minutes, the first preset value is 1.5, and the third preset value is 2.5.

[0058] Optionally, after obtaining the temperature rising data of the lint filter outlet, the method further comprises: if the temperature rising data of the lint filter outlet is less than or equal to the first preset value, controlling the compressor to continue running until the drying is completed. If the temperature rising data of the lint filter outlet is less than or equal to the first preset value, it indicates that the temperature rising is normal, and the running can be continued.

[0059] Optionally, the temperature rising data of the lint filter outlet can be obtained every preset duration to detect the temperature rising condition of the lint filter. Since lint accumulation requires a certain duration, the monitoring demand is met, and real-time monitoring is avoided to waste energy.

[0060] Optionally, the lint filter cleaning reminder can be issued by: controlling the alarm module 3 of the clothes dryer to issue an alarm, or sending lint filter cleaning information to the mobile terminal of the user.

[0061] Optionally, after the lint filter cleaning reminder is issued, the method further comprises: in response to a continue running instruction input by the user, controlling the compressor to start to continue drying.

[0062] The embodiment of the present application also provides a control device of a clothes dryer. Please refer to Figure 2 The clothes dryer includes a compressor and a lint filter, and the device includes a temperature acquisition module 1, a control module 2, and an alarm module 3.
