Description

Technical Field

[0001] The present application relates to the field of drying equipment control, and in particular, to a drying control method, electronic equipment and drying equipment. Background Art

[0002] The integrated washer-dryer is popular with most families because it can directly dry clothes after washing and drying them, eliminating the step of hanging clothes to dry. The working process of the integrated washer-dryer is as follows: After the clothes are dried, the program will start the drying system. The drying fan works, drawing the air outside the washing machine drum into the drying air inlet duct. The drying air outlet duct is equipped with a heating section of electric heating or heat pump, which heats the air sent by the drying fan and then blows it into the washing machine drum through the drying air duct outlet, where it mixes with the hot and humid air evaporated from the clothes and enters the condensation section for dehumidification. The condensed water is discharged through the drain.

[0003] For water condensing electric heating washing and drying machines, the common combination is often a pure resistance heating tube and a fixed frequency fan. As the heating tube continues to run, the fixed frequency fan delivers a relatively stable amount of heat per unit time, which can easily cause heat accumulation near the heating tube, thereby triggering the action of the temperature limiter near the heating tube. Frequent action of the temperature limiter will pose a safety hazard. Summary of the invention

[0004] The embodiments of the present application provide a drying control method, an electronic device, and a drying device to at least solve the technical problem of potential safety hazards in the drying process.

[0005] According to a first aspect of an embodiment of the present application, a drying control method is provided, which is applied to a drying device, wherein the drying device comprises a drying air duct and a processing drum, wherein a heater for heating a drying air flow is provided in the drying air duct, an air inlet of the processing drum is connected to the drying air duct, a temperature limiter for controlling the start and stop of the heater is provided at the heater, and a temperature sensor is provided at the air inlet, wherein the method comprises:

[0006] In response to a target signal indicating that the temperature of the drying airflow is stable, obtaining a temperature change of the drying airflow at the air inlet within a preset target time period;

[0007] If the temperature change indicates that the temperature of the drying airflow at the air inlet decreases, the minimum value and / or maximum value of the first start-stop interval of the heater is adjusted according to the maximum temperature collected by the temperature sensor and a preset threshold value;

[0008] Among them, the temperature limiter is associated with a preset second start-stop interval, and the temperature sensor is associated with the first start-stop interval. When the temperature detected by the temperature limiter exceeds the second start-stop interval, the temperature limiter is activated, and when the temperature detected by the temperature sensor exceeds the first start-stop interval, the heater is controlled to operate, and the adjusted first start-stop interval is smaller than the second start-stop interval.

[0009] With this embodiment, the temperature limiter can control the start and stop of the heater. If the temperature at the temperature limiter exceeds the second start-stop interval, the temperature limiter will be activated. Similarly, if the temperature at the temperature sensor exceeds the first start-stop interval, the heater will be activated. If the temperature sensor can turn off the heater before the temperature limiter is activated, the temperature at the temperature limiter will decrease, thereby avoiding the action of the temperature limiter. Based on this principle, the temperature change at the air inlet is obtained. If the temperature drops, it proves that the action of the temperature limiter causes the heater to turn off. At this time, the first start-stop interval is adjusted and the adjusted first start-stop interval is made smaller than the second start-stop interval, which can ensure that the temperature sensor can turn off the heater before the temperature limiter is activated, reduce the frequency of the temperature limiter action, and reduce safety hazards during drying.

[0010] In combination with the first aspect, in an optional implementation of the embodiment of the present application, adjusting the minimum value and / or maximum value of the first start-stop interval of the heater according to the maximum temperature collected by the temperature sensor and a preset threshold value includes:

[0011] Acquiring a maximum temperature collected by the temperature sensor in response to the target signal;

[0012] The difference between the maximum temperature and the preset first threshold is used as the minimum value of the first start-stop interval, wherein when the temperature collected by the temperature sensor is less than the minimum value, the heater is controlled to start;

[0013] The difference between the maximum temperature and the preset second threshold is used as the maximum value of the first start-stop interval, wherein when the temperature collected by the temperature sensor is greater than the maximum value, the heater is controlled to brake;

[0014] The first threshold is smaller than the second threshold.

[0015] By adopting this implementation method, the difference between the maximum temperature and the first threshold is used as the minimum value of the first start-stop interval, and the difference between the maximum temperature and the second threshold is used as the maximum value of the first start-stop interval. The calculation process is simple and fast, which is conducive to saving computing resources and reducing computing costs.

[0016] In combination with the first aspect, in an optional implementation of the embodiment of the present application, before adjusting the minimum value and / or maximum value of the first start-stop interval of the heater according to the maximum temperature collected by the temperature sensor and the preset threshold, the method further includes:

[0017] Determine whether the temperature drop amplitude represented by the temperature change exceeds a preset amplitude threshold, and if so, adjust the minimum value and / or maximum value of the first start-stop interval of the heater according to the maximum temperature collected by the temperature sensor and the preset threshold,

[0018] Otherwise, the temperature collected by the temperature sensor is reacquired after a preset target time period, and the first start-stop interval is selectively adjusted according to the maximum temperature and the temperature collected by the temperature sensor.

[0019] With this implementation, the first start-stop interval is adjusted only when the temperature drop exceeds the threshold, which helps to reduce the misjudgment rate and improve accuracy.

[0020] In combination with the first aspect, in an optional implementation manner of the embodiment of the present application, the method further includes:

[0021] If the difference between the maximum temperature and the temperature collected by the temperature sensor is not less than the amplitude threshold, adjusting the minimum value and / or maximum value of the first start-stop interval of the heater according to the maximum temperature collected by the temperature sensor and the preset threshold;

[0022] Otherwise, the step of obtaining the temperature change of the drying airflow at the air inlet within the preset target time period is re-executed, so that when the re-acquired temperature change indicates a temperature drop of the drying airflow at the air inlet, the minimum value and / or maximum value of the first start-stop interval of the heater is adjusted according to the maximum temperature collected by the temperature sensor and a preset threshold value.

[0023] By adopting this implementation method, the temperature change can be detected cyclically, thereby continuously protecting the temperature limiter.

[0024] In combination with the first aspect, in an optional implementation of the embodiment of the present application, obtaining the temperature change of the drying airflow at the air inlet within a preset target time period includes:

[0025] Acquire a first temperature detected by the temperature sensor;

[0026] After a preset target time has passed, obtaining a second temperature detected by the temperature sensor;

[0027] If the second temperature is not greater than the first temperature, the difference between the first temperature and the second temperature is taken as the temperature change.

[0028] By adopting this implementation method, the target time length is set between the first temperature and the second temperature, which is beneficial to improving the reliability of detecting the temperature change of the drying airflow at the air inlet.

[0029] In combination with the first aspect, in an optional implementation manner of the embodiment of the present application, the method further includes:

[0030] In response to the start signal for the heater, the step of obtaining the temperature change of the drying airflow at the air inlet within a preset target time period is performed.

[0031] By adopting this implementation, that is, the temperature change is detected only when the heater is turned on, which is conducive to reducing the monitoring time of the temperature change in the drying control method, thereby reducing the amount of data and reducing the calculation cost.

[0032] In combination with the first aspect, in an optional implementation manner of the embodiment of the present application, the method further includes:

[0033] If the temperature collected by the temperature sensor is not less than a preset start threshold, the target signal is generated or the step of obtaining the temperature change of the drying airflow at the air inlet within a preset target time period is executed.

[0034] With this implementation, if the temperature collected by the temperature sensor is lower than the start threshold, it proves that the current drying temperature is low and temperature fluctuations are likely to occur. Therefore, no temperature change detection is performed, which is beneficial to reducing the misjudgment rate.

[0035] According to a second aspect of an embodiment of the present application, a control method for a clothing processing device is provided, including the drying control method described above.

[0036] According to a third aspect of an embodiment of the present application, an electronic device is provided, the electronic device comprising a memory and a processor;

[0037] The memory is used to store computer programs;

[0038] The processor is used to execute the computer program to implement the steps of the method described above.

[0039] According to a fourth aspect of an embodiment of the present application, a drying device is provided, comprising the electronic device described above.

[0040] In combination with the fourth aspect, in an optional implementation of the embodiment of the present application, the drying equipment includes at least one of a dryer and a washer-dryer.

[0041] The technical effects obtained in the above-mentioned second to fourth aspects are similar to the technical effects obtained by the corresponding technical means in the first aspect, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0047] It should be understood that the "plurality" mentioned in this article refers to two or more. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and so on are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second" and so on do not limit the quantity and execution order, and the words "first", "second" and so on do not limit certain different

[0048] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0049] The integrated washer-dryer is popular with most families because it can directly dry clothes after washing and drying them, eliminating the step of hanging clothes to dry. The working process of the integrated washer-dryer is as follows: After the clothes are dried, the program will start the drying system. The drying fan works, drawing the air outside the washing machine drum into the drying air inlet duct. The drying air outlet duct is equipped with a heating section of electric heating or heat pump, which heats the air sent by the drying fan and then blows it into the washing machine drum through the drying air duct outlet, where it mixes with the hot and humid air evaporated from the clothes and enters the condensation section for dehumidification. The condensed water is discharged through the drain.

[0050] For water condensing electric heating washing and drying machines, the common combination often uses pure resistance heating tubes and fixed frequency fans. Under high voltage (253V and above), the fan speed will not increase significantly, that is, the heat dissipation of the electric heating air duct has not changed, but the heat generated by the electric heating has increased a lot in the same time. Q=U²t / R, the normal voltage is 220V, and the heat generated in the same time when it is increased to 253V increases by 1.3225 times. This causes the temperature of the electric heating air duct to be much higher than normal. Heat will accumulate near the electric heating. It is possible that during the drying process, the air inlet temperature sensor (usually placed at the air inlet of the drum to detect the temperature of the gas entering the drum and use this temperature to control the on and off of the electric heating) does not reach the set stop temperature, and the temperature limiter for safety protection will be activated. Generally, two temperature limiters are placed near the electric heating, one that can be automatically reset and the other that cannot be automatically reset. The limit value that can be automatically reset is lower than the limit value that cannot be automatically reset. When the area near the electric heater is overheated, the automatic temperature limiter will protect, disconnect the electric heating circuit, stop heating, and restart heating after the temperature drops. Repeated on and off at high voltage will not only affect the life of the temperature limiter, but also the repeated action of the automatic temperature limiter will cause adhesion and temperature drift, which will cause the manual temperature limiter to operate, seriously affecting user use. Because the manual temperature limiter cannot be automatically reset once it is activated, it needs to be disassembled and manually reset. And if it happens too many times, there will be safety hazards.

[0051] In order to solve the above problems, the embodiments of the present application provide a drying control method, an electronic device and a drying device. In the drying judgment stage, the temperature value of the air inlet temperature sensor is detected in real time. According to whether the temperature value is in a decreasing state when the electric heating is a start signal, it is judged whether the electric heating start and stop of the current drying process is controlled by the air inlet sensor or the automatic temperature limiter. If it is controlled by the temperature limiter, the new start and stop temperature is determined according to the maximum value reached by the actual temperature, so as to solve the situation under special conditions such as ultra-high voltage and high initial temperature in the drum, drying clothes, etc., that the temperature limiter takes precedence over the sensor to actually control the power on and off of the electric heating.

[0052] Among them, the air inlet temperature sensor always detects the air inlet temperature. During the drying and dryness judgment stage, the start and stop of the electric heating is mechanically controlled by the air inlet temperature sensor (relatively far away from the electric heating air inlet) and two temperature limiters relatively close to the electric heating. When the temperature of the air inlet temperature sensor reaches the preset value, the heating stops. If the temperature limiter is activated, the electric heating circuit is physically disconnected. Because the temperature of the air inlet temperature sensor has not reached the preset value, the main control board of the whole machine will issue a command to continue heating. If there is an instruction to continue heating, but the actual detection temperature of the air inlet temperature sensor drops, it means that there is actually no heating, so the temperature limiter is activated.

[0053] like Figure 1 As shown, an embodiment of the present application provides a drying control method, which is applied to a drying device, wherein the drying device includes a drying air duct and a processing drum, a heater for heating the drying airflow is provided in the drying air duct, the air inlet of the processing drum is connected to the drying air duct, a temperature limiter for controlling the start and stop of the heater is provided at the heater, and a temperature sensor is provided at the air inlet, and the method includes the following processing process.

[0054] S100 , in response to a target signal indicating that the temperature of the drying airflow is stable, obtaining a temperature change of the drying airflow at the air inlet within a preset target time period.

[0055] In one embodiment, the target signal may be a signal for entering the drying determination stage, because in the drying determination stage, the temperature of the drying airflow is relatively stable. In another embodiment, the target signal may be a signal generated after the drying airflow temperature is detected to be stable during the drying process. Specifically, the drying airflow temperature is stable, for example, the fluctuation range of the drying airflow temperature within 10s or 20s is detected to be less than 3 degrees Celsius, which is not specifically limited in this embodiment.

[0056] S102: If the temperature change indicates that the temperature of the drying airflow at the air inlet decreases, adjust the minimum value and / or maximum value of the first start-stop interval of the heater according to the maximum temperature collected by the temperature sensor and a preset threshold value.

[0057] Among them, the temperature limiter is associated with a preset second start-stop interval, and the temperature sensor is associated with the first start-stop interval. When the temperature detected by the temperature limiter exceeds the second start-stop interval, the temperature limiter is activated, and when the temperature detected by the temperature sensor exceeds the first start-stop interval, the heater is controlled to operate, and the adjusted first start-stop interval is smaller than the second start-stop interval.

[0058] In one embodiment, if the temperature detected by the thermostat exceeds the upper limit of the second start-stop interval, the thermostat will automatically disconnect to cut off the power supply to the heater. When the temperature detected by the thermostat exceeds the lower limit of the second start-stop interval, the thermostat will automatically close to resume power supply to the heater for heating. In other embodiments, the thermostat may be a manual limiter, that is, after the thermostat disconnects, it cannot automatically close and needs to be manually closed by the user to resume power supply to the heater.

[0059] Since the temperature change is obtained after the drying air flow temperature stabilizes, when the temperature change indicates a drop in the drying air flow temperature, it proves that the temperature limiter is disconnected, causing the heater to lose power. At this time, the first start-stop interval is adjusted until at least one adjustment is made so that the first start-stop interval is smaller than the second start-stop interval. In this way, the heater can be turned off before the temperature limiter is disconnected, thereby avoiding the action of the temperature limiter.

[0060] With this embodiment, the temperature limiter can control the start and stop of the heater. If the temperature at the temperature limiter exceeds the second start-stop interval, the temperature limiter will be activated. Similarly, if the temperature at the temperature sensor exceeds the first start-stop interval, the heater will be activated. If the temperature sensor can turn off the heater before the temperature limiter is activated, the temperature at the temperature limiter will decrease, thereby avoiding the action of the temperature limiter. Based on this principle, the temperature change at the air inlet is obtained. If the temperature drops, it proves that the action of the temperature limiter causes the heater to turn off. At this time, the first start-stop interval is adjusted and the adjusted first start-stop interval is made smaller than the second start-stop interval, which can ensure that the temperature sensor can turn off the heater before the temperature limiter is activated, reduce the frequency of the temperature limiter action, and reduce safety hazards during drying.

[0061] In a possible embodiment of the present application, adjusting the minimum value and / or maximum value of the first start-stop interval of the heater according to the maximum temperature collected by the temperature sensor and a preset threshold value includes:

[0062] Acquiring a maximum temperature collected by the temperature sensor in response to the target signal;

[0063] The difference between the maximum temperature and the preset first threshold is used as the minimum value of the first start-stop interval, wherein when the temperature collected by the temperature sensor is less than the minimum value, the heater is controlled to start;

[0064] The difference between the maximum temperature and the preset second threshold is used as the maximum value of the first start-stop interval, wherein when the temperature collected by the temperature sensor is greater than the maximum value, the heater is controlled to brake;

[0065] The first threshold is smaller than the second threshold.

[0066] In one embodiment, the temperature sensor periodically collects the temperature at the air inlet and records the maximum temperature collected.

[0067] By adopting this implementation method, the difference between the maximum temperature and the first threshold is used as the minimum value of the first start-stop interval, and the difference between the maximum temperature and the second threshold is used as the maximum value of the first start-stop interval. The calculation process is simple and fast, which is conducive to saving computing resources and reducing computing costs.

[0068] Optionally, in an implementation of this embodiment, before adjusting the minimum value and / or maximum value of the first start-stop interval of the heater according to the maximum temperature collected by the temperature sensor and a preset threshold, the method further includes:

[0069] Determine whether the temperature drop amplitude represented by the temperature change exceeds a preset amplitude threshold, and if so, adjust the minimum value and / or maximum value of the first start-stop interval of the heater according to the maximum temperature collected by the temperature sensor and the preset threshold,

[0070] Otherwise, the temperature collected by the temperature sensor is reacquired after a preset target time period, and the first start-stop interval is selectively adjusted according to the maximum temperature and the temperature collected by the temperature sensor.

[0071] In one embodiment, the amplitude threshold can be set according to actual needs, and this embodiment does not specifically limit this. If the temperature drop does not exceed the amplitude threshold, the temperature at the air inlet will be collected again, and then it will be determined whether the first start-stop interval needs to be adjusted again based on the previously recorded maximum temperature. It should be noted that each temperature collected by the temperature sensor will be recorded and judged whether it is the maximum temperature, and the maximum temperature will be updated in time.

[0072] With this implementation, the first start-stop interval is adjusted only when the temperature drop exceeds the threshold, which helps to reduce the misjudgment rate and improve accuracy.

[0073] Optionally, in an implementation of this embodiment, the method further includes:

[0074] If the difference between the maximum temperature and the temperature collected by the temperature sensor is not less than the amplitude threshold, adjusting the minimum value and / or maximum value of the first start-stop interval of the heater according to the maximum temperature collected by the temperature sensor and the preset threshold;

[0075] Otherwise, the step of obtaining the temperature change of the drying airflow at the air inlet within the preset target time period is re-executed, so that when the re-acquired temperature change indicates a temperature drop of the drying airflow at the air inlet, the minimum value and / or maximum value of the first start-stop interval of the heater is adjusted according to the maximum temperature collected by the temperature sensor and a preset threshold value.

[0076] By adopting this implementation method, the temperature change can be detected cyclically, thereby continuously protecting the temperature limiter.

[0077] Optionally, in an implementation of this embodiment, the obtaining of the temperature change of the drying airflow at the air inlet within a preset target time period includes:

[0078] Acquire a first temperature detected by the temperature sensor;

[0079] After a preset target time has passed, obtaining a second temperature detected by the temperature sensor;

[0080] If the second temperature is not greater than the first temperature, the difference between the first temperature and the second temperature is taken as the temperature change.

[0081] Specifically, the temperature change is represented by the difference between the first temperature and the second temperature.

[0082] By adopting this implementation method, the target time length is set between the first temperature and the second temperature, which is beneficial to improving the reliability of detecting the temperature change of the drying airflow at the air inlet.

[0083] Optionally, in an implementation of this embodiment, the method further includes:

[0084] In response to the start signal for the heater, the step of obtaining the temperature change of the drying airflow at the air inlet within a preset target time period is performed.

[0085] It should be noted that the start signal is a signal sent by the system to turn on the heater, but since the heater is controlled by the temperature limiter and is in a power-off state, in one embodiment, as long as the start signal sent by the system is received, the subsequent steps are executed without being affected by the actual state of the temperature limiter.

[0086] By adopting this implementation, that is, the temperature change is detected only when the heater is turned on, which is conducive to reducing the monitoring time of the temperature change in the drying control method, thereby reducing the amount of data and reducing the calculation cost.

[0087] Optionally, in an implementation of this embodiment, the method further includes:

[0088] If the temperature collected by the temperature sensor is not less than a preset start threshold, the target signal is generated or the step of obtaining the temperature change of the drying airflow at the air inlet within a preset target time period is executed.

[0089] With this implementation, if the temperature collected by the temperature sensor is lower than the start threshold, it proves that the current drying temperature is low and temperature fluctuations are likely to occur. Therefore, no temperature change detection is performed, which is beneficial to reducing the misjudgment rate.

[0090] An embodiment of the present application also provides a control method for a clothing processing device, including the drying control method described above.

[0091] In the above-mentioned embodiments of the present application, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments. The steps shown in the relevant flow chart can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flow chart, in some cases, the steps shown or described can be executed in an order different from that here. In other words, the order of steps described in the foregoing embodiments is only an example, and it is also within the scope of protection of the embodiments of the present application to reasonably adjust the order of steps based on the content of the embodiments of the present application.

[0092] In a specific implementation of the embodiment of the present application, the drying control method includes the following processing steps:

[0093] like Figure 2 As shown, X: real-time monitoring value of the inlet air temperature sensing package.

[0094] T: Temperature threshold. Detection starts only when the temperature exceeds this threshold. T should be greater than 70℃ and less than 90℃.

[0095] t: threshold, fixed time, should not be too long, should not exceed 30s.

[0096] X1: Temperature variable detected by the inlet air temperature sensor.

[0097] K: Threshold, 3℃~10℃ is optimal.

[0098] K': threshold, 3~5℃ is optimal.

[0099] K”: threshold, 13~15℃ is optimal.

[0100] Y: Maximum value of X detected.

[0101] Y1: Temperature variable detected by the inlet air temperature sensing package.

[0102] Drying can be roughly divided into three stages: drying heating, drying judgment, and drying cooling. In the drying judgment stage, stable dehumidification begins and automatic dryness is judged.

[0103] Run the drying program until the drying judgment stage. Monitor the air inlet sensor temperature X in real time, and start drying protection only when the temperature reaches the threshold T. If it is less than T, there will be problems such as not drying dry or drying time is too long. If there is thermal dehydration, the initial temperature is low, and temperature fluctuations will occur. This protection logic will cause false detection problems, so it is necessary to detect when it is stable above T (after it has been stably heated for a period of time).

[0104] The controller reads whether the electric heater is given an on signal. If it is, it reads the temperature value X1. If the electric heater is given an on signal, but the actual temperature is lower, it proves that the automatic temperature limit has been activated, and the start and stop temperature of the electric heater must be lowered (controlled by the air inlet sensor). Because the existing controller cannot perform linear analysis and can only perform point-to-point detection, a temperature detection is performed every fixed time t. If the temperature does not rise after time t, it is considered that the automatic temperature limiter may have been activated. Detect whether the temperature drop reaches the threshold K. If not, record the X value at this time, record it as Y, and use this Y value as the detection benchmark. Detect the temperature drop every fixed time. If the temperature does not drop to the K value, continue to detect. If it is greater than K, adjust the start and stop temperature of the electric heater. Adjust to Y-K' off, YK" on.

[0105] When X=X1, it is considered that a temperature rise and fall cycle is completed within time t. Although the possibility is very small, the start and stop temperatures are adjusted directly based on X.

[0106] Special note: if the electric heating is turned off within ts, stop the test and restart from the beginning of the flowchart.

[0107] The core points include:

[0108] 1. Only detect when the electric heating is turned on;

[0109] 2. Only detect when the electric heating temperature exceeds T℃;

[0110] 3. Perform temperature judgment once every ts, and take the highest temperature point detected as the reference judgment point;

[0111] 4. When the temperature drops by K℃, adjust the start and stop temperature of the electric heating;

[0112] 5. The temperature after ts is equal to the temperature before ts, adjust the start and stop temperature of the electric heating

[0113] In another application scenario, Figure 3 As shown, for a controller that can directly produce a temperature curve, it is possible to directly determine when the highest temperature detected by the air inlet temperature sensing package is reached. If it is a signal to turn on the electric heating, but the temperature drops, it is determined that the automatic temperature limiter is in action.

[0117] Specifically, Figure 4 As shown, the electronic device includes a processor 100, at least one communication bus 200, a user interface 300, at least one external communication interface 400 and a memory 500. The communication bus 200 is configured to realize connection and communication between these components. The user interface 300 may include a display screen, and the external communication interface 400 may include a standard wired interface and a wireless interface. The memory 500 stores a drying control method. The processor 100 is used to adopt the above method when executing the drying control method stored in the memory 500.
