[0045] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as being limited to the embodiments described herein, which are instead provided for a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not intended to limit the scope of protection of the present disclosure.

The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least one other embodiment"; the term "some embodiments" means "at least some embodiments". Relevant definitions of other terms will be given in the description below. It should be noted that the concepts of "first", "second", etc. mentioned in this disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the processes performed by these devices, modules or units.

[0047] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0048] In view of the problem mentioned in the background art that a wet load is put into a clothes dryer but a drying program is forgotten to be started, resulting in the wet load being left in the clothes dryer for a long time and becoming moldy, an embodiment of the present disclosure provides a control method for a clothes dryer.

[0049] Through the analysis of the prior art, it is found that, except for the reasons of user usage habits and negligence, the existing dryer cannot perform the corresponding detection operation when the drying operation is not started, and cannot sense the presence of wet load in the drying drum. To solve this defect, the embodiment of the present disclosure provides a control method for a dryer, which can still perform the corresponding detection operation when the drying operation is not started, and then determine whether there is a load in the drying drum, thereby providing a possibility for prompting the user. It should be noted that the control method for the dryer provided in the embodiment of the present disclosure can only be executed when the dryer is powered on.

[0050] Figure 1 is a flow chart of a control method for a clothes dryer provided by an embodiment of the present disclosure. Figure 1 As shown, the control method of the dryer provided by the example of the present disclosure includes S110-S140.

[0051] S110: Determine that the drum door of the clothes dryer is closed and the clothes dryer does not start a drying operation, and detect a first humidity of the air in the drying drum of the clothes dryer.

[0052] In most cases, after the user places the wet load to be dried into the drying drum of the clothes dryer, the user will close the drum door of the clothes dryer. In addition, only when the drum door of the clothes dryer is closed can the drying drum space of the clothes dryer be isolated from the outside space, so as to prevent the humid air in the outside environment from entering the clothes processing barrel of the clothes dryer and affecting the subsequent detection operation. For this reason, in the embodiment of the present disclosure, closing the drum door of the clothes dryer is a necessary condition for starting the subsequent control operation. That is to say, the subsequent detection operation will be performed only when the drum door of the clothes dryer is closed.

[0053] In actual applications, after the user closes the dryer door, the drying operation of the dryer may be triggered. In this case, there is no need to perform subsequent detection operations. Only when the user closes the dryer door but does not trigger the drying operation of the dryer, is it necessary to perform subsequent detection operations.

[0054] Based on the analysis of the above two related factors, in the example of the present disclosure, when it is determined that the drum door of the dryer is closed and the drying operation of the dryer is not started, the first humidity of the air in the drying drum of the dryer is detected.

[0055] In actual applications, after the user closes the dryer drum door, he or she also needs to select the type of load to be dried, the drying mode, and the drying dryness. The drying operation of the dryer will not be started until the above parameters are set. In other words, it will take some time between closing the dryer drum door and actually starting the drying operation. If the first humidity of the air in the drying drum is detected immediately after determining that the dryer drum door is closed, the first humidity may be useless due to the start of the drying operation. To avoid this problem, in some embodiments, S110 may specifically include S111.

[0056] S111: Determine that the drum door of the dryer is closed, and the dryer does not start a drying operation after a second period of time, and detect a first humidity of the air in the drying drum of the dryer.

[0057] That is to say, in some embodiments, after determining that the drum door of the clothes dryer is closed, it is necessary to wait for a second time period before determining whether the clothes dryer starts the drying operation. In specific implementation, the second time period can be determined according to the time required for the user to set parameters such as the type of drying load, the drying mode, and the drying dryness. Specifically, the second time period should be slightly longer than the time required for the user to set the drying load type, the drying mode, the drying dryness, and other parameters. However, it should be noted that in order to avoid the first humidity being unrepresentative, the second time period should not be too long.

[0058] Of course, in some other embodiments, the first humidity of the air in the drying drum of the clothes dryer may also be detected immediately after it is determined that the drum door of the clothes dryer is closed.

[0059] In actual applications, the first humidity is likely to be a smaller humidity value. For example, if the drum door is not closed before the clothes dryer is used, the first humidity is the air humidity. For another example, if the user takes out the dried clothes from the clothes dryer last time and immediately closes the drum door, the first humidity is basically 0.

[0060] S120: Detecting a second humidity of the air in the drying drum after a first period of time has passed.

[0061] The first time length is the time length required for the free water in the wet load to be dried to volatilize more fully and for the air humidity in the drying drum to be increased as much as possible. The reasonable value of the first time length can be set based on experience.

[0062] In practical applications, if a wet load is put into the drying drum of the clothes dryer and the clothes dryer does not start the drying operation, the free water in the wet load to be dried will evaporate due to the low humidity in the drying drum, causing the humidity in the drying drum to increase. That is to say, in most cases, after the first period of time, the second humidity of the air in the drying drum is greater than the first humidity, and in most cases is much greater than the first humidity.

[0063] It should be noted that the second humidity of the air in the drying drum is detected after the first time period, which is performed when the clothes dryer has not started the drying operation. If the clothes dryer starts the drying operation at a certain moment, the operation of S120 is no longer performed.

[0064] S130: Calculate a first humidity difference between the second humidity and the first humidity, and determine whether the first humidity difference is greater than a reference humidity difference; if so, execute S140.

[0065] After obtaining the aforementioned first humidity and second humidity, the first humidity difference between the first humidity and the second humidity can be calculated. In a specific implementation, the first humidity difference is obtained by subtracting the first humidity from the second humidity.

[0066] The reference humidity difference is a reference value determined through experiments or experience, which indicates whether the humidity change in the drying drum is too large.

[0067] If the first humidity difference is greater than the reference humidity difference, it is determined that the change in the air humidity in the drying drum is too large after the first time period has passed, and it can be determined that there is a wet load in the drying drum of the clothes dryer.

[0068] S140: Output prompt information.

[0069] The prompt information in the embodiment of the present disclosure is information indicating that there is a wet load in the dryer but the dryer has not started the drying operation.

[0070] In the embodiment of the present disclosure, when it is determined that the drying load of the clothes dryer is loaded but the clothes dryer has not started the drying operation, it is determined that the user has forgotten to trigger the start of the drying program. At this time, a prompt message can be output to prompt the user to set the drying program and start the drying operation.

[0071] According to the control method of the clothes dryer provided by the embodiment of the present disclosure, when it is determined that the drum door of the clothes dryer is closed and the clothes dryer has not started the drying operation, the first humidity of the air in the drying drum of the clothes dryer is detected, and the second humidity of the air in the drying drum is detected after the second time period. When the first humidity difference between the first humidity and the second humidity is greater than the reference humidity difference, it is determined that there is a wet load in the drying drum, and thus a prompt message is output. Based on the control method of the clothes dryer provided by the embodiment of the present disclosure, when there is a wet load in the clothes dryer but the user forgets to start the drying operation, the user can be prompted to start the drying operation, thereby avoiding the problem of failure to dry the load in time due to negligence of the user, and thus avoiding various problems caused by failure to dry the load in time.

[0072] In practical applications, the first humidity and the second humidity generated by the sensor may be inaccurate due to accidental factors and noise.

[0073] In order to avoid the aforementioned problems, in the embodiment of the present disclosure, the first humidity of the air in the drying drum of the dryer can be detected. The humidity detection can be performed multiple times within a short period of time when it is determined that the drying operation of the dryer has not been started to obtain multiple detection values, and the average of the multiple detection values ​​can be calculated as the first humidity.

[0074] In addition, in order to avoid the aforementioned problem, S120 detecting the second controlled humidity of the air in the drying drum after the first period of time may specifically include S121.

[0075] S121: After the first time period has passed, detecting the second humidity of the air in the drying drum once at intervals of a third time period within a set period.

[0076] If the load in the drying drum of the clothes dryer is a wet load and the clothes dryer is in the starting drying operation, the air humidity in the drying drum will gradually increase until it reaches saturation. Therefore, the second humidity can be tested at intervals within the continuous set time period after the first time period, and the aforementioned multiple second humidities can be compared with the first humidity to determine whether there is a wet load in the clothes dryer.

[0077] The corresponding aforementioned S140 may include S131: respectively calculating the first humidity difference between each second humidity and the first humidity, and determining whether there is a preset number of first humidity difference values ​​greater than the reference humidity difference value; if so, executing S140.

[0078] In the above-mentioned embodiment, the difference between each second humidity and the first humidity is calculated to determine a plurality of first humidity differences, and a prompt message is output when a set number of first humidity differences are greater than a reference humidity difference. In other embodiments, the weighted average of each second humidity may be taken to obtain an average humidity, and then the average humidity is subtracted from the first humidity to obtain a first humidity difference, and whether to output a prompt message is determined based on a comparison result between the first humidity difference and the weighted humidity difference.

[0079] Figure 2 is a flow chart of a control method for a clothes dryer provided by some other embodiments of the present disclosure. Figure 2 As shown, in some other embodiments of the present disclosure, the control method of the dryer includes S210-S260.

[0080] S210: Determine that a drum door of the clothes dryer is closed and the clothes dryer has not started a drying operation, and detect a first humidity of air in a drying drum of the clothes dryer;

[0081] S220: Detecting a second humidity of the air in the drying drum after the first period of time has passed.

[0082] S230: Calculate a first humidity difference between the second humidity and the first humidity, and determine whether the first humidity difference is greater than a reference humidity difference; if so, execute S240; if not, execute S250.

[0083] S240: Output prompt information.

[0084] As in the previous embodiment, the prompt information is information indicating that there is a wet load in the dryer but the dryer has not started the drying operation.

[0085] In the embodiment of the present disclosure, S210-S240 are the same as S110-S140 described above and will not be repeated here. For details, please refer to the description in the previous text.

[0086] S250: After a fourth period of time, detect a third humidity of the air in the drying drum.

[0087] S260: Calculate the second humidity difference between the third humidity detected again and the first humidity, and determine whether the second humidity difference is greater than the reference humidity difference; if so, execute S240; if not, execute S250.

[0088] In the disclosed embodiment, after determining that the first humidity difference is not greater than the reference humidity difference, it is not directly determined that there is no wet load in the clothes dryer, but the air humidity in the drying drum is continuously detected after the fourth time period to obtain a third humidity, and then the second humidity difference between the third humidity and the first humidity is calculated, and whether there is a wet load in the drying drum of the clothes dryer is determined based on the second humidity difference. If it is determined that there is a wet load in the drying drum at this time, a prompt message is also output. If it is not possible to determine whether there is a wet load in the drying drum after measuring the third humidity once, humidity detection is continued, and judgment is continued based on the third humidity obtained by subsequent humidity detection.

[0089] In actual application, the user may not put a load in the drying drum, but only close the door of the drying drum. In this case, it is meaningless to execute the aforementioned S250-S260 in a loop. To avoid this problem, in some embodiments, before executing S250 to detect the third humidity of the air in the drying drum, S270 and S280 may also be executed.

[0090] S270: Determine whether the closing duration of the drum door is less than the fifth duration, and the fifth duration is greater than the sum of the first duration and the two fourth durations; if so, execute S250 to detect the third humidity of the air in the drying drum; if not, execute S280.

[0091] S280: It is determined that there is no wet load in the drying drum of the clothes dryer.

[0092] By executing S270, when it is determined that the closing time of the drum door is greater than or equal to the fifth time period, the aforementioned S250-S260 cycle can be directly jumped out, and it can be directly determined that there is no wet load in the drying drum, thereby avoiding the long-term detection operation of the dryer.

[0093] The above described embodiment determines whether there is a wet load in the clothes dryer by humidity detection. In other embodiments, in addition to humidity detection, temperature detection can also be combined to determine whether there is a wet load in the clothes dryer.

[0094] Figure 3 1 is a flow chart of a control method for a clothes dryer provided in some embodiments of the present disclosure. Figure 3 As shown, in some further embodiments, the control method of the dryer includes S310-S340.

[0095] S310: Determine that the drum door of the clothes dryer is closed and the clothes dryer does not start a drying operation, detect a first humidity of the air in the drying drum of the clothes dryer, and detect a first temperature of the drying drum.

[0096] S320: Detecting a second humidity of the air in the drying drum after the first period of time has passed, and detecting a second temperature of the drying drum.

[0097] S340: Calculate the first humidity difference between the second humidity and the first humidity, calculate the first temperature difference between the first temperature and the second temperature, and determine whether the first humidity difference is greater than the reference humidity difference and whether the first temperature difference is greater than the reference temperature difference; if both are true, execute S340.

[0098] S340: Output prompt information.

[0099] The prompt message is a message indicating that there is a wet load in the dryer but the dryer has not started the drying operation.

[0100] In actual applications, the wet load put into the drying drum of the clothes dryer is mostly the load that has been rinsed with cold water. After being rinsed with cold water, the temperature of the wet load is roughly the temperature of the cold water, which is lower than the temperature of the drying drum. If the wet load is put into the drying drum but no drying operation is performed, the temperature of the drying drum will decrease due to the heat absorption of the wet load itself and the heat absorption of the evaporation of the water, so that the first temperature of the drying drum detected before and the second temperature detected after the first time are different, and the second temperature is lower than the first temperature.

[0101] Based on the considerations in the preceding paragraph, in some embodiments, while calculating the first humidity difference between the second humidity and the first humidity, the first temperature difference between the first temperature and the second temperature is calculated, and while determining whether the first humidity difference is greater than the reference humidity difference, the first temperature difference is determined to be greater than the reference temperature difference. If both of the above determinations are established, it can be more confidently determined that the load in the drying drum is a wet load, and a prompt message can be output.

[0102] As mentioned above, when it is determined that there is a wet load in the dryer and the dryer has not started the drying operation, a prompt message can be output. In some embodiments, the output prompt message can be directly output by the dryer, specifically, the prompt message can be output in the form of a buzzer prompt, or the prompt details can be output in the form of a voice prompt. In some other embodiments, the output prompt message can be sent to a user terminal, and the terminal program installed in the user terminal pushes the prompt message to the user.

[0103] In a specific implementation, if the user receives the prompt information, it is likely that the drying control parameters of the clothes dryer can be configured and the drying operation can be started. In other embodiments, the user may not receive the prompt information. At this time, if the wet load is left in the drying drum for a long time, the problem of clothes getting moldy will still occur. In order to avoid the aforementioned problem, in some embodiments, if the drying start operation instruction triggered by the user is not received after the sixth time period, the drying operation is started according to the preset mode. The aforementioned preset mode can be a mode of using a lower drying temperature to dry the wet load to avoid damaging the load.

[0104] In addition to providing the aforementioned control method for a clothes dryer, an embodiment of the present disclosure also provides a control device for a clothes dryer. Figure 4 Schematic diagram of the structure of the control device of the clothes dryer provided by the embodiment of the present disclosure. Figure 4 As shown, the control device 400 of the clothes dryer includes a control unit 401 , a calculation unit 402 , a determination unit 403 and a prompt unit 404 .

[0105] The control unit 401 is used to determine that the drum door of the dryer is closed and the drying operation of the dryer is not started, detect a first humidity of the air in the drying drum of the dryer; and detect a second humidity of the air in the drying drum after a first period of time.

[0106] The calculation unit 402 is used to calculate a first humidity difference between the second humidity and the first humidity.

[0107] The judging unit 403 is used to judge whether the first humidity difference is greater than the reference humidity difference, and to determine that there is a wet load in the drying drum when the first humidity difference is greater than the reference humidity difference.

[0108] The prompt unit 404 is configured to output a prompt message when the first humidity difference is greater than a reference humidity difference.

[0109] In some embodiments, the control unit 401 determines that the drum door of the clothes dryer is closed, and the clothes dryer does not start the drying operation after a second period of time.

[0110] In some embodiments, the control unit 401 controls to detect the second humidity of the air in the drying drum once every third time period within a set period after the first time period has passed; the calculation unit 402 calculates the first humidity difference between each second humidity and the first humidity. The judgment unit 403 judges whether there is a preset number of first humidity difference values ​​greater than the reference humidity difference value. The prompt unit 404 outputs a prompt message when the preset number of first humidity difference values ​​is greater than the reference humidity difference value.

[0111] In some embodiments, when the judgment unit 403 determines that the humidity difference is less than or equal to the reference humidity difference, the control unit 401 controls the detection of the third humidity of the air in the drying drum after the fourth time period, the calculation unit 402 calculates the second humidity difference between the third humidity detected again and the first humidity, and the judgment unit 403 determines whether the second humidity difference is greater than the reference humidity difference. The prompt unit 404 outputs a prompt message when the second humidity difference is greater than the reference humidity difference; when the second humidity difference is less than or equal to the reference humidity difference, the control unit 401 is triggered to execute the step of detecting the third humidity of the air in the drying drum again after the fourth time period.

[0112] In some embodiments, before the control unit 401 controls the step of re-detecting the third humidity of the air in the drying drum, the judgment unit 403 determines whether the duration of the closure of the drum door is less than the fifth time period, and the fifth time period is greater than the sum of the first time period and the two fourth time periods; when the duration of the closure of the drum door is less than the fifth time period, the control unit 401 detects the third humidity of the air in the drying drum again.

[0113] In some embodiments, while controlling and detecting a first humidity of the air in the drying drum of the dryer, the control unit 401 controls and detects a first temperature of the drying drum; while detecting a second humidity of the air in the drying drum after a first period of time, the control unit 401 controls and detects a second temperature of the drying drum; the calculation unit 402 calculates a first temperature difference between the first temperature and the second temperature, and the judgment unit 403 further judges whether the first temperature difference is greater than a reference temperature difference; the output unit 404 outputs a prompt message when the first humidity difference is greater than the reference humidity difference and the temperature difference is greater than the reference temperature difference.

[0114] In some embodiments, the prompt unit 404 outputs the prompt information in the form of a buzzer prompt or a voice prompt; or sends the prompt information to the user terminal.

[0115] In some embodiments, when no drying start operation instruction is received after the sixth time period, the control unit 401 automatically starts the drying operation according to a preset mode.

[0116] In addition to providing the aforementioned control method and control device for a clothes dryer, an embodiment of the present disclosure further provides a clothes dryer. Figure 5 Schematic diagram of the structure of the clothes dryer provided by the present disclosure. Figure 5 As shown, the clothes dryer includes a controller 501, a drying drum 502 and a humidity sensor 503.
