[0055] The technical solutions in the embodiments of the present application will be described clearly and completely 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, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0056] See also Figure 1 , Figure 1A schematic diagram of the first flow chart of the control method of a clothes dryer provided in an embodiment of the present application. An embodiment of the present application provides a control method of a clothes dryer, and the clothes dryer may be an exhaust-type clothes dryer, a heat pump-type clothes dryer, or a condensing-type clothes dryer, etc. A device with a drying function in a washing machine may also be called a clothes dryer. The clothes dryer may include a housing and a door, and the door may be rotatably connected to the housing. Of course, the clothes dryer may also include components such as a display panel, a motor, a rotating shaft, an inner drum, etc., which are not specifically limited here. The control method of the clothes dryer includes:

[0057] 101. During the clothes drying process, detect whether the door is opened.

[0058] Most of the existing dryers advertise that they will stop when the clothes are dry and users can open the door to take out clothes at any time. Therefore, many dryers do not have a locking function when drying to facilitate users to open the door at any time. After the door is opened during the operation of the dryer, the dryer will usually restart the program or continue to run the remaining program according to the user's instructions. The operation stage of the dryer is controlled according to the user's instructions, which is prone to user misjudgment, resulting in problems such as too long drying time or clothes not being dried.

[0059] The embodiment of the present application provides a control method for a clothes dryer to solve the above-mentioned problem.

[0060] During the drying process, it is detected whether the door is opened. Drying clothes can correspond to multiple operation stages, such as heating stage, drying stage, steam stage, cooling stage and wrinkle removal stage. An inner drum can be set in the box, the inner drum is used to carry clothes, and the inner drum can rotate relative to the box.

[0061] In the heating stage, the inside of the box or the inner drum is heated to remove part of the water vapor or speed up the drying process. The heating stage can be achieved by a heating component, which may include a compressor, an evaporator, a condenser and an air duct. The air duct is connected to the inner drum to provide hot air for the inner drum. For example, for a heat pump dryer, the air in the heat pump dryer is heated to dry hot air by the heat energy generated by the compression and decompression of the heat pump. The dry hot air passes through the wet clothes, and the residual moisture on the clothes absorbs heat and becomes hot and humid air. The hot and humid air is converted into dry cold air after passing through the condenser, and the water vapor in the air condenses into water droplets and is discharged. At this time, the dry cold air continues to be heated by the heat energy generated by the compression and decompression of the heat pump, and participates in the entire drying process again and again, and the cycle continues until the wet clothes are dried. When the heat pump dryer is running, like ordinary air conditioners, it absorbs energy QA in the low-temperature environment medium in the evaporator, consumes part of the energy, that is, the compressor consumes QB, and the refrigerant circulation system releases heat QC in the condenser. QC=QA+QB, so the efficiency of the heat pump dryer is (QA+QB) / QB, and the heating efficiency of other heating devices is less than 1, so the heating efficiency of the heat pump dryer is much higher than that of other heating devices.

[0062] In the drying stage, after the box is heated to a preset temperature, the inner drum is controlled to rotate, which drives the clothes to turn over, so that the drying is more uniform. Therefore, the drying stage can be the operation stage after the heating stage. It should be noted that the drying stage can also be divided into a constant temperature maintenance stage and a low temperature stage. The constant temperature maintenance stage is to dry at a preset temperature. Since the constant temperature stage can remove moisture that is easier to remove from the clothes, the moisture content in the clothes is relatively low at this time. In order to save energy, another low temperature can be used for drying, that is, drying at a temperature lower than the preset temperature. This stage can be called a low temperature stage, which can not only achieve the drying of clothes, but also save energy.

[0063] In the steam stage, high-temperature steam can be generated in the box to sterilize the clothes. In some embodiments, the steam stage may not be set or executed, and other methods may be used for sterilization, such as using the preset temperature of the drying stage for sterilization. Another example is to set an ultraviolet lamp for sterilization.

[0064] The cooling stage is the stage of cooling down after the clothes are dried to prevent burns to the user. At this time, the compressor has stopped and the inner drum has stopped rotating.

[0065] In the wrinkle removal stage, high-temperature steam can be used to remove wrinkles from clothes, improve the wrinkles of clothes, and enhance the user experience. The wrinkle removal stage can be performed after the drying stage. For example, after washing the clothes, put the clothes into the dryer, and the dryer automatically enters the wrinkle removal stage after drying the clothes. The wrinkle removal stage can also be a separate operation stage. For example, users can put clean and dry clothes into the dryer for wrinkle removal.

[0066] Since the dryer has different processing in each operation stage, the state of the clothes in the cabinet is also different. If you continue to run the remaining programs or re-run the programs after opening the door regardless of the operation stage, the state of the clothes will not match the operation stage. For example, in the drying stage, the user opens the door to add clothes to be dried. If you continue to run the remaining programs after closing the door, and continue to run the remaining drying time that matches the previous amount of clothes, it is easy to cause the clothes to not be dried. For another example, if the user opens the door to take out the clothes to be dried, if you continue to run the remaining programs or re-run the programs after closing the door, it is easy to cause the drying time to be too long.

[0067] Therefore, in the embodiment of the present application, during the clothes drying process, for example, whether the door is opened is detected in each operation stage, or at least whether the door is opened is detected in two of the operation stages, such as the drying stage and the wrinkle removal stage, so as to provide a suitable operation mode for each operation stage, thereby improving the drying efficiency of the clothes.

[0068] The detection of whether the door is opened can be achieved by detecting the state of the door and the box body from being locked to being separated. For example, an infrared sensor or a distance sensor can be set to determine whether the door is opened through signal feedback.

[0069] 102. If yes, obtain the environmental parameters in the box and / or the running time of the current running stage.

[0070] 103. Determine the operation phase of the dryer according to environmental parameters and / or operation duration.

[0071] Regarding steps 102 and 103:

[0072] After detecting that the door is opened, the environmental parameters in the box and / or the operating time of the current stage can be detected.

[0073] The environmental parameters in the cabinet may include temperature and humidity. The environmental parameters may be detected once when the door is opened and again after the door is closed, and the operation stage of the dryer may be determined based on the comparison of the two times. For example, the operation stage of the dryer may be to restart the current stage, continue the current stage, return to the previous operation stage, or enter the next operation stage.

[0074] The environmental parameters may be acquired through an environmental sensor, which may include a temperature sensor and a humidity sensor, or the environmental sensor may be an integrated sensor capable of detecting temperature and humidity.

[0075] The operation time of the current operation stage may include the operation time that has been executed in the current operation stage, the remaining operation time of the current operation stage, and the preset operation time of the current stage. The operation stage of the clothes dryer is determined according to the operation time, for example, the current stage may be restarted, the current stage may be continued, the previous operation stage may be returned, or the next operation stage may be entered.

[0076] The detection of the running time can be obtained by a timer. The timer can time the current running stage to obtain the running time that has been executed in the current running stage or the remaining running time of the current running stage.

[0077] After the operation stage of the clothes dryer is determined according to the environmental parameters and / or the operation duration, the operation stage can be executed after the door is closed. In other words, after the door is opened and closed, the above environmental parameters and / or the operation duration are detected, and after the operation program of the clothes dryer is determined, the instruction can be executed, that is, the instruction to re-run the current stage, continue to run the current stage, return to the previous operation stage, or enter the next operation stage.

[0078] In the control method of the clothes dryer provided in the embodiment of the present application, when the door is detected to be opened in the middle of the operation of the clothes dryer during the drying process, the operation stage of the clothes dryer is determined according to the environmental parameters in the cabinet and / or the operation time of the current operation stage, that is, the corresponding operation stage is automatically entered according to the actual state of the clothes, which can improve the drying efficiency and reduce the problems of too long drying time or clothes not being dried. In addition, the above process does not require manual intervention, and the clothes dryer automatically determines, and the degree of intelligence of the clothes dryer is high.

[0079] The following will explain the control method of the dryer from different operating stages.

[0080] Please combine Figure 1 Also see Figure 2 , Figure 2 A second flow chart of the control method for a clothes dryer provided in an embodiment of the present application. The embodiment of the present application also provides a control method for a clothes dryer, and the clothes dryer may be an exhaust-type clothes dryer, a heat pump-type clothes dryer, or a condensing-type clothes dryer, etc. A device with a drying function in a washing machine may also be called a clothes dryer. The clothes dryer may include a housing and a door, and the door may be rotatably connected to the housing. Of course, the clothes dryer may also include components such as a display panel, a motor, a rotating shaft, an inner drum, etc., which are not specifically limited here. The control method for the clothes dryer includes:

[0081] 201. During the temperature rise phase of the clothes drying process, detect whether the door is opened.

[0082] Most of the existing dryers advertise that they will stop when the clothes are dry and users can open the door to take out clothes at any time. Therefore, many dryers do not have a locking function when drying to facilitate users to open the door at any time. After the door is opened during the operation of the dryer, the dryer will usually restart the program or continue to run the remaining program according to the user's instructions. The operation stage of the dryer is controlled according to the user's instructions, which is prone to user misjudgment, resulting in problems such as too long drying time or clothes not being dried.

[0083] In the heating stage, the inside of the box or the inner drum is heated to remove part of the water vapor or speed up the drying process. The heating stage can be achieved by a heating component, which may include a compressor, an evaporator, a condenser and an air duct. The air duct is connected to the inner drum to provide hot air for the inner drum. For example, for a heat pump dryer, the air in the heat pump dryer is heated to dry hot air by the heat energy generated by the compression and decompression of the heat pump. The dry hot air passes through the wet clothes, and the residual moisture on the clothes absorbs heat and becomes hot and humid air. The hot and humid air is converted into dry cold air after passing through the condenser, and the water vapor in the air condenses into water droplets and is discharged. At this time, the dry cold air continues to be heated by the heat energy generated by the compression and decompression of the heat pump, and participates in the entire drying process again and again, and the cycle continues until the wet clothes are dried. When the heat pump dryer is running, like ordinary air conditioners, it absorbs energy QA in the low-temperature environment medium in the evaporator, consumes part of the energy, that is, the compressor consumes QB, and the refrigerant circulation system releases heat QC in the condenser. QC=QA+QB, so the efficiency of the heat pump dryer is (QA+QB) / QB, and the heating efficiency of other heating devices is less than 1, so the heating efficiency of the heat pump dryer is much higher than that of other heating devices.

[0084] In the heating stage, it is detected whether the door is opened, so as to determine the operation stage of the dryer after the door is closed. In some cases, the dryer has started to run, and the user finds that there are still clothes that need to be dried that have not been added, so the door can be opened to place the clothes to be added.

[0085] Detecting whether the door is opened can be achieved by detecting the state of the door and the box body from being locked to being separated. For example, an infrared sensor or a distance sensor can be set to determine whether the door is opened through signal feedback.

[0086] 202. If yes, obtain the temperature inside the box.

[0087] 203. When the door is closed and the temperature is within the temperature threshold, the dryer is controlled to continue to operate in the heating stage.

[0088] Regarding steps 202 and 203:

[0089] During the heating stage, the cabinet is heated and heat exchange is performed. In this process, the temperature inside the cabinet is a parameter to measure the progress of this stage. After detecting that the door is opened, the temperature inside the cabinet can be detected in real time. When the door is closed and the temperature inside the cabinet is within the temperature threshold, the dryer can be controlled to continue running the heating stage. It can be understood that the heating stage is a process in which the temperature continues to rise. If clothes are added or reduced during this process, the heating can continue according to the temperature inside the cabinet after the door is closed. The difference is that it takes longer to heat to the preset temperature after adding clothes than when no clothes are added, and it takes shorter to heat to the preset temperature after reducing clothes than when no clothes are reduced.

[0090] Therefore, in the heating stage, when it is detected that the door is opened, after the door is closed, when the temperature inside the cabinet is within the temperature threshold, the dryer is controlled to continue to run the heating stage, but at this time the remaining running time of the heating stage will be determined according to the real-time temperature inside the cabinet. Of course, after the door is closed, if the temperature inside the cabinet exceeds the temperature threshold, the next operation stage can be entered. For example, when the user adds warmer clothes into the dryer and blows hot air into the cabinet of the dryer, the temperature inside the cabinet can reach or even exceed the temperature threshold, and the next operation stage can be entered directly.

[0091] During the heating stage, after the door is opened and closed, the operating program of the dryer is determined according to the temperature inside the cabinet, that is, the actual state of the clothes is adapted to the operating stage of the dryer, which can improve the drying efficiency of the clothes and prevent the clothes from being dried for too long or not being dried at all.

[0092] Please combine Figure 1 Also see Figure 3 , Figure 3 A third flow chart of the control method for a clothes dryer provided in an embodiment of the present application. The embodiment of the present application also provides a control method for a clothes dryer, and the clothes dryer may be an exhaust-type clothes dryer, a heat pump-type clothes dryer, or a condensing-type clothes dryer, etc. A device with a drying function in a washing machine may also be called a clothes dryer. The clothes dryer may include a housing and a door, and the door may be rotatably connected to the housing. Of course, the clothes dryer may also include components such as a display panel, a motor, a rotating shaft, an inner drum, etc., which are not specifically limited here. The control method for the clothes dryer includes:

[0093] 301. During the drying stage of the clothes drying process, detect whether the door is opened.

[0094] Most of the existing dryers advertise that they will stop when the clothes are dry and users can open the door to take out clothes at any time. Therefore, many dryers do not have a locking function when drying to facilitate users to open the door at any time. After the door is opened during the operation of the dryer, the dryer will usually restart the program or continue to run the remaining program according to the user's instructions. The operation stage of the dryer is controlled according to the user's instructions, which is prone to user misjudgment, resulting in problems such as too long drying time or clothes not being dried.

[0095] In the drying stage, after the box is heated to a preset temperature, the inner drum is controlled to rotate, which drives the clothes to turn over, so that the drying is more uniform. Therefore, the drying stage can be the operation stage after the heating stage. It should be noted that the drying stage can also be divided into a constant temperature maintenance stage and a low temperature stage. The constant temperature maintenance stage is to dry at a preset temperature. Since the constant temperature stage can remove moisture that is easier to remove from the clothes, the moisture content in the clothes is relatively low at this time. In order to save energy, another low temperature can be used for drying, that is, drying at a temperature lower than the preset temperature. This stage can be called a low temperature stage, which can not only achieve the drying of clothes, but also save energy.

[0096] During the drying stage, it is detected whether the door is opened, and the operating stage of the dryer can be determined based on the environmental parameters in the cabinet after the door is opened and closed.

[0097] Detecting whether the door is opened can be achieved by detecting the state of the door and the box body from being locked to being separated. For example, an infrared sensor or a distance sensor can be set to determine whether the door is opened through signal feedback.

[0098] 302. If yes, obtain the humidity in the box.

[0099] 303. Determine the operating stage of the dryer based on humidity.

[0100] Regarding steps 302 and 303:

[0101] In the drying stage, the operation stage of the dryer can be determined according to the humidity in the cabinet. The drying stage can be divided into a constant temperature maintenance stage and a low temperature stage, and the constant temperature maintenance stage and the low temperature stage can be executed in sequence. Different control methods can correspond to these two different drying stages.

[0102] In the constant temperature maintenance stage, that is, the process in which the dryer uses a preset temperature to dry the clothes, this stage can remove the moisture contained in the clothes that is easier to remove. Therefore, humidity is a key parameter for the operation of the constant temperature maintenance stage. The first humidity in the box when the door is open and the second humidity in the box after the door is closed are obtained. If the difference between the first humidity and the second humidity is greater than the humidity difference threshold, the dryer is controlled to return to the previous operation stage. It can be understood that after the door is closed, if the humidity of the added clothes is detected to be high, the temperature of the corresponding clothes is also low. At this time, it is necessary to reheat to perform heat exchange on the clothes in the box, thereby removing part of the water vapor on the clothes. If the difference between the first humidity and the second humidity is within the humidity difference threshold, the first humidity threshold of the drying stage, that is, the constant temperature maintenance stage, is obtained, and the operation stage of the dryer is determined according to the relationship between the second humidity and the first humidity threshold. When the second humidity is greater than the first humidity threshold, it indicates that the humidity of the clothes is still high at this time, and the dryer can be controlled to continue to run the drying stage, that is, the constant temperature maintenance stage. At this time, the difference from the first humidity is the remaining operation time of the constant temperature maintenance stage. When the second humidity is within the first humidity threshold, the next operation stage is entered. It can be understood that this indicates that the humidity of the clothes has met the requirements of the first humidity threshold in the constant temperature maintenance stage, and therefore, the next operation stage can be entered, which can be a low temperature stage, a steam stage, a cooling stage, or a wrinkle removal stage.

[0103] To put it another way, during the constant temperature maintenance stage, the dryer keeps the temperature at the preset temperature and records the running time of the constant temperature maintenance stage in real time. When the door switch signal is detected to be disconnected, the electronic control system can record the current humidity value, and the running time timing is paused. When the door switch signal is turned on, the program runs, and the electronic control system can determine the relationship between the difference between the real-time humidity value and the recorded humidity value and the humidity difference threshold. If the difference between the real-time humidity value and the recorded humidity value is greater than the humidity difference threshold, it returns to the previous running stage, that is, the heating stage, and the running time of the constant temperature maintenance stage is reset. If the difference between the real-time humidity value and the recorded humidity value is within the humidity difference threshold, the program determines the relationship between the humidity at this time and the first humidity threshold of the jump stage. If the real-time humidity is greater than the first humidity threshold, the constant temperature maintenance stage continues to run, and the timing continues to increase until it jumps to the next running stage. If the real-time humidity is within the first humidity threshold, the program jumps to the next running stage, and the running time is the value when it is paused.

[0104] In the low temperature stage or the delayed drying stage, the clothes are dried at another temperature in the box, and the other temperature is lower than the preset temperature in the constant temperature maintenance stage. In this stage, humidity is still a key parameter for the operation of the dryer. In the low temperature stage, it is detected whether the door body is opened. When the door body is opened, the third humidity in the box is obtained after the door body is closed. When the third humidity is greater than the second humidity threshold of the drying stage, that is, the low temperature stage, it indicates that the humidity of the clothes is large at this time, and the dryer can be controlled to re-run the drying stage, that is, re-run the low temperature stage. When the third humidity is within the second humidity threshold, it indicates that the moisture content of the clothes meets expectations, and the dryer is controlled to continue to run the drying stage, that is, the low temperature stage. The second humidity threshold can be less than the first humidity threshold. Therefore, when the third humidity is greater than the second humidity threshold, it can be further determined whether the third humidity is within the first humidity threshold. If the third humidity is within the first humidity threshold, the low temperature stage can be re-run. If the third humidity exceeds the first humidity threshold, you can choose to return to the previous operation stage, such as returning to the constant temperature maintenance stage, or for example, you can return to the heating stage.

[0105] To put it another way, after the door closing program is run in the low temperature stage, it is necessary to judge the relationship between the real-time humidity value and the humidity threshold of the constant temperature maintenance stage jump stage. If the third humidity is greater than the second humidity threshold and greater than the first humidity threshold, the constant temperature maintenance stage is re-run. If the third humidity is within the second humidity threshold, the constant temperature maintenance stage continues to run. The running time of the low temperature stage is obtained by a second-order function of the running time of the constant temperature maintenance stage, and the running time of the constant temperature maintenance stage directly affects the value of the running time of the low temperature stage. When the third humidity is within the second humidity threshold, it is determined whether the running time of the low temperature stage is reached. When the running time of the low temperature stage ends, the next running stage can be jumped.

[0106] During the drying stage, the operating stage of the dryer is determined according to the real-time humidity value in the cabinet, that is, the operating stage of the dryer is determined according to the actual state of the clothes. This can make the actual state of the clothes match the operating stage of the dryer, thereby improving the drying efficiency and reducing the phenomenon of long drying time or incomplete drying.

[0107] Please combine Figure 1 Also see Figure 4 , Figure 4 A fourth flow chart of the control method for a clothes dryer provided in an embodiment of the present application. The embodiment of the present application also provides a control method for a clothes dryer, and the clothes dryer may be an exhaust-type clothes dryer, a heat pump-type clothes dryer, or a condensing-type clothes dryer, etc. A device with a drying function in a washing machine may also be called a clothes dryer. The clothes dryer may include a housing and a door, and the door may be rotatably connected to the housing. Of course, the clothes dryer may also include components such as a display panel, a motor, a rotating shaft, an inner drum, etc., which are not specifically limited here. The control method for the clothes dryer includes:

[0108] 401. During the steam stage of the clothes drying process, detect whether the door is opened.

[0109] Most of the existing dryers advertise that they will stop when the clothes are dry and users can open the door to take out clothes at any time. Therefore, many dryers do not have a locking function when drying to facilitate users to open the door at any time. After the door is opened during the operation of the dryer, the dryer will usually restart the program or continue to run the remaining program according to the user's instructions. The operation stage of the dryer is controlled according to the user's instructions, which is prone to user misjudgment, resulting in problems such as too long drying time or clothes not being dried.

[0110] In the steam stage, high-temperature steam can be generated in the box to sterilize the clothes. In some embodiments, the steam stage may not be set or executed, and other methods may be used for sterilization, such as using the preset temperature of the drying stage for sterilization. Another example is to set an ultraviolet lamp for sterilization. The steam stage may be a stage following the low-temperature stage.

[0111] The steam stage is usually a timed stage, that is, the stage where the steam is stopped after running for a preset time. During this process, if the door is opened, the running stage of the dryer after the door is closed needs to be determined based on the running time of the steam stage.

[0112] 402. If yes, obtain the running time of the steam stage when the door is opened.

[0113] 403. After the door is closed, if the running time is within half of the preset time of the steam stage, the steam stage is restarted; if the running time is greater than half of the preset time, the next running stage is entered.

[0114] Regarding steps 402 and 403:

[0115] Since the steam phase is a timed program, the operating phase of the dryer needs to be determined based on the running time of the steam phase.

[0116] When the door is opened, the running time of the steam stage is obtained. When the door is closed, if the running time of the steam stage is within half of the preset time of the steam stage, it means that the steam stage has been interrupted at the beginning of the operation, and the steam stage can be restarted. If the running time of the steam stage is greater than half of the preset time, it means that the sterilization or other treatment of the steam stage has been almost completed, and the steam stage can be ended or the next operation stage can be entered.

[0117] To put it another way, the steam stage has a preset duration. When the door switch signal is detected to be disconnected, the electronic control system records the running duration of the current stage. After the door is closed, the relationship between the current running duration and half of the preset duration is determined. If the current running duration is within half of the preset duration, the steam stage is restarted. If it exceeds half of the preset duration, the steam stage ends and jumps to the next running stage.

[0118] During the steam stage, the operating stage of the dryer is determined based on the relationship between the operating time when the door is opened and half of the preset time. The steam stage can be restarted when the operating time is shorter, and the steam stage can be ended when the operating time is longer, thereby improving the processing efficiency of clothes.

[0119] Please combine Figure 1 Also see Figure 5 , Figure 5 The fifth flow chart of the control method of the clothes dryer provided in the embodiment of the present application. The embodiment of the present application also provides a control method of a clothes dryer, and the clothes dryer may be an exhaust type clothes dryer, a heat pump type clothes dryer or a condensing type clothes dryer, etc., and a device with a drying function in a washing machine may also be called a clothes dryer. The clothes dryer may include a housing and a door body, and the door body is rotatably connected to the housing. Of course, the clothes dryer may also include components such as a display panel, a motor, a rotating shaft, an inner drum, etc., which are not specifically limited here. The control method of the clothes dryer includes:

[0120] 501. During the timing phase of the clothes drying process, detect whether the door is opened.

[0121] Most of the existing dryers advertise that they will stop when the clothes are dry and users can open the door to take out clothes at any time. Therefore, many dryers do not have a locking function when drying to facilitate users to open the door at any time. After the door is opened during the operation of the dryer, the dryer will usually restart the program or continue to run the remaining program according to the user's instructions. The operation stage of the dryer is controlled according to the user's instructions, which is prone to user misjudgment, resulting in problems such as too long drying time or clothes not being dried.

[0122] For the timing stage, that is, the stage that runs according to the preset duration, the timing stage can include the cooling stage and the wrinkle removal stage. The cooling stage is the stage of cooling down after the clothes are dried to prevent scalding the user. At this time, the compressor has stopped and the inner drum has stopped rotating. In the wrinkle removal stage, high-temperature steam can be used to remove wrinkles from clothes to improve the wrinkles of clothes and enhance the user experience. The wrinkle removal stage can be performed after the drying stage. For example, after washing the clothes, put the clothes into the dryer, and the dryer automatically enters the wrinkle removal stage after drying the clothes. The wrinkle removal stage can also be a separate operation stage. For example, the user can put clean and dry clothes into the dryer for wrinkle removal.

[0123] Whether the door is opened is detected during the cooling phase and the wrinkle removal phase, and the operation phase of the dryer is determined after the door is closed.

[0124] Detecting whether the door is opened can be achieved by detecting the state of the door and the box body from being locked to being separated. For example, an infrared sensor or a distance sensor can be set to determine whether the door is opened through signal feedback.

[0125] 502. If yes, after the door is closed, the timing phase is restarted.

[0126] For the cooling stage, the temperature is a reference factor for whether the cooling stage is over. When the door is opened during the cooling stage, the timing stage, i.e., the cooling stage, can be continued after the door is closed. It is understandable that when the door is opened during the cooling stage, the temperature has already dropped to a certain extent, and it is not easy to cause burns to the user. Therefore, the cooling stage can be restarted after the door is closed until the temperature drops to room temperature or a preset temperature.

[0127] In other words, the cooling stage is a timing stage with a preset duration. During this stage, the door switch signal is detected to be disconnected, the program is paused, and the program restarts the timing stage after the door is closed. When the running time reaches the preset time, it jumps to the next running stage.

[0128] 503. If yes, when the door is closed, the timing phase ends.

[0129] The wrinkle removal stage is a timing stage of a preset duration. If the door switch signal is detected to be disconnected during this stage, the program ends directly and returns to the standby state. It can be understood that the wrinkle removal stage is to take care of the clothes. If the user opens the door during this stage, it means that the clothes do not need to be cared for, or the basic care has been completed, and the operation stage can be ended directly.

[0130] During the timing stage, the operating status of the dryer can be determined by detecting whether the door is opened, which can improve the drying efficiency.

[0131] In the control method of the clothes dryer provided in the embodiment of the present application, when the door is detected to be opened in the middle of the operation of the clothes dryer during the drying process, the operation stage of the clothes dryer is determined according to the environmental parameters in the cabinet and / or the operation time of the current operation stage, that is, the corresponding operation stage is automatically entered according to the actual state of the clothes, which can improve the drying efficiency and reduce the problems of too long drying time or clothes not being dried. In addition, the above process does not require manual intervention, and the clothes dryer automatically determines, and the degree of intelligence of the clothes dryer is high.

[0132] In order to better implement the control method of the clothes dryer in the embodiment of the present application, the embodiment of the present application also provides a control device for the clothes dryer.
