Description

Technical Field

[0001] The present invention relates to the technical field of clothes dryers, and in particular provides a control method for a clothes dryer. Background Art

[0002] With the continuous improvement of living standards, people's demand for household appliances is also getting higher and higher. The demand for clothing processing equipment is not only for washing and drying, but also for drying. The emergence of dryers meets the needs of most users, but the clothes in the dryer are prone to entanglement during use, resulting in the outer clothes being dried while the inner clothes are still wet. At this time, the drying effect is poor, which greatly reduces the user experience. In addition, in order to ensure the drying effect, some dryers are equipped with a shaking function, that is, the shaking program is executed during the drying process. However, when the clothes are not entangled, the execution of the shaking program wastes drying time and reduces the drying efficiency.

[0003] Accordingly, the art needs a new control method for a dryer to solve the problem in the prior art that the drying effect or drying efficiency is poor after the clothes in the dryer are tangled together. Summary of the invention

[0004] The present invention aims to solve the above technical problem, that is, to solve the problem in the prior art that the drying effect or drying efficiency of the clothes in the dryer is poor after the clothes are tangled together.

[0005] In a first aspect, the present invention provides a control method for a clothes dryer, wherein an image acquisition device is provided in the clothes dryer, and the control method comprises: acquiring image information of dried clothes after the clothes dryer executes a drying mode for a first time; determining whether the dried clothes are clumped; and when the dried clothes are determined to be clumped, controlling the clothes dryer to execute a shaking mode.

[0006] In a preferred technical solution of the control method of the above-mentioned clothes dryer, the control method further comprises: when the dried clothes are not clumped, controlling the clothes dryer to continue to execute the drying mode.

[0007] In the preferred technical solution of the control method of the above-mentioned dryer, the control method also includes: after the shaking mode is executed, reacquiring the image information of the dried clothes; when the dried clothes are judged to be clumped, controlling the dryer to execute the shaking mode for a second time; and / or, when the dried clothes are not clumped, controlling the dryer to continue to execute the drying mode.

[0008] In the preferred technical solution of the above-mentioned control method of the dryer, the step of "obtaining image information of dried clothes after the dryer executes the drying mode for the first time" further includes: obtaining images of dried clothes every T1 time after the dryer executes the drying mode for the first time.

[0009] In a preferred technical solution of the above-mentioned control method for the clothes dryer, the shaking mode includes controlling the clothes dryer to execute forward rotation for a time T2 and reverse rotation for a time T3.

[0010] In a preferred technical solution of the control method of the above-mentioned clothes dryer, the control method further comprises: the forward rotation and the reverse rotation are each performed n times, and the forward rotation and the reverse rotation are performed alternately.

[0011] In a preferred technical solution of the control method of the above-mentioned clothes dryer, the control method further comprises: the forward rotation during the time T2 is rotated at a first speed, and the reverse rotation during the time T3 is rotated at a second speed.

[0012] In a preferred technical solution of the control method of the above-mentioned clothes dryer, the control method further includes: when the dried clothes are judged to be clumped, the drying mode and the shaking mode of the clothes dryer are executed simultaneously.

[0013] In the preferred technical solution of the control method of the above-mentioned clothes dryer, the control method further includes: obtaining the execution times of the shaking mode; when the execution times are greater than the first execution times, controlling the clothes dryer to execute the alarm mode.

[0014] In the preferred technical solution of the control method of the above-mentioned clothes dryer, the control method further comprises: after executing the alarm mode, clearing the number of executions of the shaking mode.

[0015] When the above technical solution is adopted, the clothes dryer is drying clothes while the inner drum of the dryer is rotating. The rotation of the inner drum may cause the clothes to clumping, and the outer clothes may wrap the inner clothes. During the drying process, the outer clothes wrap the inner clothes so that the outer clothes are dried when the inner clothes are still wet. Therefore, after detecting whether the clothes are completely dried, the dryer may easily mistakenly determine that the clothes have been completely dried and terminate the operation. In order to avoid the above situation, it is necessary to first determine whether the clothes are clumped or stacked. The determination of whether the clothes are clumped is performed after the first drying mode is executed. Since the drying mode has been executed for a period of time, with the rotation of the inner drum of the dryer, the clothes may clumping. Therefore, it is necessary to first obtain image information of the clothes through an image acquisition device to determine whether the clothes are clumped. When the clothes are judged to be clumped, the shaking mode needs to be executed. In order to ensure the drying efficiency, when the clothes are judged to be clumped, the drying mode of the dryer can be executed at the same time as the shaking mode. The shaking-out mode may be to control the dryer to execute forward rotation for T2 time and reverse rotation for T3 time, with the forward rotation and reverse rotation being executed n times each, and the forward rotation and reverse rotation being performed alternately. Since the dried clothes are likely to become tangled when the inner drum continuously rotates in one direction, it is necessary to control the inner drum of the dryer to rotate forward and reverse alternately. Since the dried clothes may clumping when the inner drum of the dryer rotates in a certain direction, the clumping may be aggravated easily with the increase of the rotation time, thereby causing the inner layer of the dried clothes to be wet while the outer layer is dry after clumping. When the dried clothes have clumped, alternating the inner drum forward rotation and reverse rotation may alleviate the clumping phenomenon. After the clothes have rotated in one direction for a period of time, if they are rotated in the opposite direction, the clumped clothes may be untied. When the inner drum rotates forward and reversely alternately, the inner drum may be controlled to rotate forward at a first speed for T2 time and reverse at a second speed for T3 time, thereby shaking out the clothes.

[0020] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0021] It should be noted that in the description of the present invention, the terms "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second" and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0022] like Figure 1-3 As shown, in order to solve the problem in the prior art that the drying effect or drying efficiency is poor after the clothes in the dryer are tangled together, the dryer of the present invention includes an image acquisition device for acquiring information of the dried clothes in the dryer, so as to determine whether the dried clothes are clumped.

[0023] like Figure 1 FIG. 1 is a flow chart showing the main steps of the control method for a clothes dryer of the present invention, which specifically includes the following steps:

[0024] Step S100: After the clothes dryer executes the drying mode for the first time, image information of the drying clothes is obtained;

[0025] Step S200: determining whether the dried clothes are clumped;

[0026] Step S210: When the dried clothes are judged to be clumped, the dryer is controlled to execute a shaking mode.

[0027] When the clothes dryer is drying clothes, the inner drum of the clothes dryer will rotate. The inner drum may cause the clothes to clumping during the rotation of the inner drum, and the outer clothes may wrap the inner clothes. During the drying process, the outer clothes wrap the inner clothes, so that the outer clothes are dried when the inner clothes are still wet. Therefore, after detecting whether the clothes are completely dried, the clothes dryer may easily mistakenly determine that the clothes have been completely dried and end the operation. The result caused by the above setting seriously affects the user experience. In order to avoid the above situation, it is necessary to first determine whether the clothes are clumped or whether the clothes are stacked. It should be noted that the clothes clumping described in the present invention can be clothes entangled together or clothes wrapped together, or clothes stacked together. The above is not restrictive and can be set according to the needs of technicians in this field. The present invention determines whether the clothes are clumped after the drying mode is executed for the first time. Since the drying mode has been executed for a period of time, as the inner drum of the dryer rotates, the clothes may clumped. Therefore, it is necessary to first obtain the image information of the clothes through the image acquisition device to determine whether the clothes are clumped. When the clothes are judged to be clumped, the shaking mode needs to be executed. In order to ensure the drying efficiency, when the dried clothes are judged to be clumped, the drying mode of the dryer can be executed at the same time as the shaking mode. Of course, according to the needs of those skilled in the art, the drying mode can be not executed when the shaking mode is executed. It should be noted that the above-mentioned image acquisition device can be set as a camera device or other device capable of image acquisition. The above is not restrictive and can be set according to the needs of those skilled in the art.

[0028] like Figure 2 FIG. 1 is a flowchart of specific steps of a first embodiment of a control method for a clothes dryer of the present invention, which specifically includes the following steps:

[0029] Step S100: After the clothes dryer executes the drying mode for the first time, image information of the drying clothes is obtained;

[0030] Step S200: determining whether the dried clothes are clumped;

[0031] Step S210: When the dried clothes are judged to be clumped, the clothes dryer is controlled to execute a shaking mode;

[0032] Step S220: When the dried clothes are not clumped, the clothes dryer is controlled to continue to execute the drying mode.

[0033] When the clothes dryer is drying clothes, the inner drum of the dryer will rotate. The inner drum may cause the clothes to clumping, and the outer clothes may wrap the inner clothes. During the drying process, the outer clothes wrap the inner clothes, so that the outer clothes are dried when the inner clothes are still wet. Therefore, after detecting whether the clothes are completely dried, the dryer may easily mistakenly determine that the clothes have been completely dried and end the operation. The result caused by the above settings seriously affects the user experience. In order to avoid the above situation, it is necessary to first determine whether the clothes are clumped or stacked or entangled with each other. When the clothes are judged to be clumped, the shaking mode needs to be executed. When the dryer detects that the dried clothes are not clumped, it proves that the clothes are not entangled or wrapped together during the rotation of the inner drum. Therefore, the drying efficiency of the dryer can be guaranteed without executing the shaking mode. Therefore, the dryer can continue to execute the drying mode.

[0034] In the prior art, there are clothes dryers that can execute the shaking mode. In this case, the clothes dryer directly executes the shaking mode after executing the drying mode for a period of time, without judging whether the clothes are clumped. However, when the clothes are not clumped and the shaking mode is executed, the drying speed of the clothes may be reduced and the drying time may be increased. The present invention can solve the above problems. The clothes dryer of the present invention judges whether the clothes are clumped during the execution of the drying mode. When the clothes are not clumped, there is no need to execute the unnecessary shaking mode, which saves the drying steps and ensures that the clothes are dried efficiently. At the same time, it can also save drying time. When the clothes are clumped, executing the shaking mode can reduce the entanglement problem of the clothes during the drying process, and avoid the problem that the clothes cannot be completely dried due to the entanglement of the clothes. The high efficiency of the drying of the clothes dryer is achieved through the above judgment.

[0035] like Figure 3 FIG. 1 is a flowchart of specific steps of a second embodiment of the control method for a clothes dryer of the present invention, which specifically includes the following steps:

[0036] Step S100: After the clothes dryer executes the drying mode for the first time, image information of the drying clothes is obtained;

[0037] Step S200: determining whether the dried clothes are clumped;

[0038] Step S210: When the dried clothes are judged to be clumped, the clothes dryer is controlled to execute a shaking mode;

[0039] Step S300: after the shaking mode is executed, reacquiring image information of the drying clothes;

[0040] Step S310: determining whether the dried clothes are clumped;

[0041] Step S3101: when the dried clothes are judged to be clumped, controlling the clothes dryer to execute a second time shaking mode;

[0042] Step S3102: When the dried clothes are not clumped, control the dryer to continue the drying mode.

[0043] When the dried clothes are judged to be clumped, the shaking mode can be executed at the same time as the drying mode. Of course, the shaking mode can also be executed separately. After the shaking mode is completed, continue to detect whether the dried clothes are clumped. If the dried clothes are still in a clumped state, it proves that the clothes are entangled or wrapped too tightly and need to continue to execute the shaking mode. If the dried clothes are no longer clumped, continue to execute the drying mode. Since the clothes may be seriously tangled during the drying process, even if the shaking mode is executed multiple times, the dried clothes cannot be separated. Therefore, in order to avoid the shaking mode having no effect or no obvious effect, it can be judged that the shaking mode is ineffective after a certain number of times, and other operations need to be performed. For example, after the shaking mode is executed, the number of executions of the shaking mode is obtained. After the number of executions of the shaking mode reaches the first number of executions, if it is detected that the dried clothes are still in a clumping state, it is determined that the dried clothes cannot be shaken apart even if the shaking mode is executed. Therefore, the alarm mode needs to be activated. The alarm mode can notify the user that the dried clothes have clumped. Therefore, after receiving the alarm signal, the user can take out the dried clothes by himself after the drying mode of the drying clothes ends and determine whether the dried clothes have been completely dried. If the dried clothes are completely dried, the dried clothes are taken out and placed in the set position. If the dried clothes are not completely dried, some clothes are in a wet state and some clothes have been completely dried, then the tangled dried clothes need to be separated and the clothes that need to be dried need to be dried again.

[0044] Of course, the above is not restrictive. When the dryer executes the alarm mode, the user can also suspend the operation of the dryer during the drying process of the clothes, and take out the clothes to separate the knotted parts. Since the clothes may be stretched or wrinkled when they are dried in a knotted state, the clothes are also easily damaged. Therefore, in order to ensure the drying effect of the clothes and avoid damage to the clothes, the clothes can be taken out during the drying process and the clothes can be separated and then put into the dryer for drying. The above is not restrictive and can be set according to the needs of technicians in this field. Of course, the dryer can also stop the drying work while executing the alarm mode, and after stopping for a period of time, it detects that the gas in the dryer is a safe temperature that cannot burn the user and reminds the user to come and separate the knotted clothes. After separating the knotted clothes, the user puts the clothes into the dryer again for drying.

[0045] In addition, since the alarm times are cumulative, in order to ensure the accuracy of the alarm mode execution, the execution times of the shaking mode are reset to zero after the alarm mode is executed. It should also be noted that the execution times of the shaking mode of the dryer are reset to zero after each dryer operation to ensure the accuracy of the next use of the dryer.

[0046] It should be noted that after the drying mode is executed for the first time, it is necessary to control the dryer to detect whether the clothes are clumped. If the clothes are clumped, the shaking mode is executed. After the shaking mode is completed, the detection of whether the clothes are clumped continues. Of course, the above is not fixed, and it is not necessary to detect whether the clothes are clumped immediately after each shaking mode ends. It is also possible to re-detect whether the clothes are clumped after a period of time after the shaking mode ends. Of course, the detection time of whether the clothes are clumped can also be set to a fixed time. For example, after the dryer executes the drying mode for the first time, the image of the dried clothes is obtained every T1 time. Detecting whether the clothes are clumped every T1 time can reduce the probability of clothes clumping as much as possible, and can timely determine whether the clothes are clumped, and deal with the clumped clothes in time. Of course, obtaining the image information of the dried clothes can also be performed at T1 time after the shaking mode is completed. The above is not restrictive and can be set according to the needs of technicians in this field.

[0047] It should also be noted that the above-mentioned shaking-out mode can be to control the dryer to execute forward rotation for T2 time and reverse rotation for T3 time, with the forward rotation and reverse rotation being executed n times each, and the forward rotation and reverse rotation being performed alternately. Since the dried clothes are likely to become tangled when the inner drum continuously rotates in one direction, it is necessary to control the inner drum of the dryer to rotate forward and reverse alternately. Since the dried clothes will form a ball when the inner drum of the dryer rotates in a certain direction, the balling situation will easily be aggravated as the rotation time increases, thereby causing the inner layer of the dried clothes to be wet while the outer layer of the clothes is dry after the balling. When the dried clothes have already formed a ball, alternating the inner drum forward rotation and reverse rotation can alleviate the above-mentioned balling phenomenon. After the clothes have been rotated in one direction for a period of time, if they are rotated in the opposite direction, the above-mentioned balled clothes can be untied. When the inner drum rotates forward and reverse alternately, the inner drum can be controlled to rotate forward at a first speed for T2 time and reverse at a second speed for T3 time, thereby shaking out the clothes.

[0048] It should be noted that the T2 time and the T3 time can be the same duration or different durations, and the first speed and the second speed can be the same speed or different speeds. The above are not restrictive and can be set according to the needs of those skilled in the art, and all of the above are within the protection scope of the present invention. In addition, since the rotation speed of the inner drum is slow in the drying mode, the inner drum can also rotate forward and reverse at a low speed in the shaking mode to ensure that the dried clothes can be dried while being shaken.

[0049] It should also be noted that the forward rotation of T2 time and the reverse rotation of T3 time can be continuous, that is, the reverse rotation of T3 time is performed immediately after the forward rotation of T2 time. Of course, there can also be a slight pause after the forward rotation of T2 time, and then the reverse rotation of T3 time is performed. The above is not restrictive and can be set according to the needs of technical personnel in this field.

[0050] In addition, the execution of the shaking mode of the present invention can also be performed under the execution of other modes. For example, when the dryer is capable of washing and spinning, it can be determined whether the clothes are clumped during the washing and spinning process of the dryer. It should be noted that if the clothes are detected to be clumped during the washing or spinning process, the clothes can also be tangled by alternating forward and reverse rotation of the dryer. Of course, the rotation speed of the inner drum of the dryer can be selected to be the same as the rotation speed of the inner drum in the washing or spinning program. The above is not restrictive and can be set according to the needs of technicians in this field.

[0051] In summary, during the drying process of the clothes dryer, the inner drum of the clothes dryer rotates, and the clothes may be clumped during the rotation of the inner drum, and the outer clothes may wrap the inner clothes. During the drying process, the outer clothes wrap the inner clothes, so that the outer clothes are dried when the inner clothes are still wet. Therefore, after detecting whether the clothes are completely dried, the clothes dryer may mistakenly determine that the clothes have been completely dried and end the operation. The result caused by the above setting seriously affects the user experience. In order to avoid the above situation, it is necessary to first determine whether the clothes are clumped or stacked. The determination of whether the clothes are clumped in the present invention is after executing the first drying mode. Since the drying mode has been executed for a period of time, with the rotation of the inner drum of the clothes dryer, the clothes may clumped. Therefore, it is necessary to first obtain the image information of the clothes through the image acquisition device to determine whether the clothes are clumped. When the clothes are judged to be clumped, the shaking mode needs to be executed. In order to ensure the drying efficiency, when the clothes are judged to be clumped, the drying mode of the clothes dryer can be executed at the same time as the shaking mode. When the dried clothes are judged to be clumped, the shaking mode can be executed at the same time as the drying mode. Of course, the shaking mode can also be executed separately. After the shaking mode is completed, continue to detect whether the dried clothes are clumped. If the dried clothes are still in a clumped state, it proves that the clothes are entangled or wrapped too tightly and need to continue to execute the shaking mode. If the dried clothes are no longer clumped, continue to execute the drying mode. Since the clothes may be seriously tangled during the drying process, even if the shaking mode is executed multiple times, the dried clothes cannot be separated. Therefore, in order to avoid the shaking mode having no effect or no obvious effect, it can be judged that the shaking mode is ineffective after a certain number of times, and other operations need to be performed. For example, after the shaking mode is executed, the number of executions of the shaking mode is obtained. After the number of executions of the shaking mode reaches the first number of executions, if it is detected that the dried clothes are still in a clumping state, it is determined that the dried clothes cannot be shaken apart even if the shaking mode is executed. Therefore, the alarm mode needs to be activated. The alarm mode can notify the user that the dried clothes have clumped. Therefore, after receiving the alarm signal, the user can take out the dried clothes by himself after the drying mode of the drying clothes ends and determine whether the dried clothes have been completely dried. If the dried clothes are completely dried, the dried clothes are taken out and placed in the set position. If the dried clothes are not completely dried, some clothes are in a wet state and some clothes have been completely dried, then the tangled dried clothes need to be separated and the clothes that need to be dried need to be dried again.

[0052] It should be noted that the above-mentioned implementation mode is only used to illustrate the principle of the present invention and is not intended to limit the scope of protection of the present invention. Without departing from the principle of the present invention, those skilled in the art can adjust the above-mentioned structure so that the present invention can be applied to more specific application scenarios.

[0053] So far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
