[0022] 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.

In addition, the terms "first", "second" and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0024] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] like Figure 1-4 As shown, in order to solve the problem in the prior art that the drying time of clothes is inaccurate and thus affects the wearing of clothes or causes waste of electricity resources, the dryer of the present invention includes a multi-spectral camera, which is installed in the dryer so that it can take pictures of the clothes in the dryer.

[0026] like Figure 1 FIG. 1 is a main flow chart of the control method of a clothes dryer based on multispectral imaging of the present invention, which specifically includes the following steps:

[0027] Step S100: After the clothes dryer executes the drying mode for the first time, controlling the clothes dryer to obtain image information of the clothes;

[0028] Step S200: controlling the clothes dryer to compare the image information with the first preset image information;

[0029] Step S300: selectively controlling the clothes dryer to continue the drying mode or stop drying according to the comparison result.

[0030] The multispectral camera can take pictures of the clothes in the dryer to obtain image information, and the image information includes RGB values ​​and / or near-infrared values. The following is introduced by setting the image information to RGB values ​​as an example. Before the dryer performs the drying program, the multispectral camera collects a large number of images during the drying process. The image information mainly collects RGB values ​​of the clothes in three states during the drying process, for example, the RGB values ​​of the clothes in a relatively wet state, in a semi-dry state, and in a completely dry state. The RGB values ​​in the image information are calculated by the detection and analysis device in the dryer to obtain the RGB values ​​in the above three states and store them in the dryer. The following is introduced by setting the information in the completely dried state in the stored information as the first preset image information as an example. In the subsequent drying process of the clothes, the image information of the clothes is obtained by the multispectral camera and compared with the first preset image information stored in the dryer, so as to determine whether the clothes are currently completely dried, and then more accurately determine whether the dryer needs to stop running.

[0031] It should be noted that the image information can be collected for three states of the clothes in the drying process. Of course, it can also be more or fewer states. For example, only the RGB values ​​of the clothes in the completely dried state can be collected. The above is not restrictive. As long as it can determine whether the clothes are completely dried, the above are all within the protection scope of the present invention.

[0032] It should also be noted that the image information obtained in the present invention is introduced using RGB values ​​as an example, but this is not restrictive and can also be introduced based on near-infrared values. Of course, it can also be introduced based on a combination of RGB values ​​and near-infrared values ​​as an example. Therefore, all of the above are within the protection scope of the present invention.

[0033] like Figure 2 As shown, a first specific implementation of the control method of a clothes dryer based on multispectral imaging of the present invention is shown, which specifically includes the following steps:

[0034] Step S100: After the clothes dryer executes the drying mode for the first time, controlling the clothes dryer to obtain image information of the clothes;

[0035] Step S200: controlling the clothes dryer to compare the image information with the first preset image information;

[0036] Step S310: determining whether the image information is lower than the first preset image information;

[0037] Step S311: when the image information is lower than the first preset image information, controlling the clothes dryer to continue to execute the drying mode;

[0038] Step S312: When the image information is not lower than the first preset image information, the clothes dryer is controlled to stop drying.

[0039] The present invention can adopt different ways to acquire image information. After the dryer executes the drying mode for the first time, the dryer is controlled to acquire the image information of the clothes in real time. When the clothes are completely dried, the operation of the dryer can be stopped in time, thereby saving the power resources of the dryer and ensuring the timeliness and intelligence of the clothes drying. Of course, the acquisition of image information can also be done once every period of time. When the image information is lower than the first preset image information, the dryer is controlled to continue to execute the drying mode, and then the dryer is controlled to acquire the image information of the clothes every T1 time. By acquiring the image information of the clothes every T1 time, the dryer can be prevented from being in the situation of judging the image information and the corresponding first preset image information in real time, thereby reducing the working time of the processing device of the dryer, and further delaying the service life of the processing device of the dryer. In addition, after the clothes are completely dried, in order to avoid the problem that the user forgets to take out the clothes and the clothes are placed in the dryer for too long, after the dryer stops drying, the dryer is controlled to execute the reminder mode to remind the user to take out the clothes. The reminder mode can be in many ways, for example, controlling the light of the dryer to flash, or reminding the user through a whistle sound. When the dryer is connected to the communication device used by the user, it can also send a message to the communication device to remind the user to take out the clothes. The above is not restrictive and can be set according to the needs of technical personnel in this field. Therefore, the above are all within the scope of protection of the present invention.

[0040] like Figure 3 FIG. 2 is a second specific implementation of the control method of a clothes dryer based on multispectral imaging of the present invention, which specifically includes the following steps:

[0041] Step S100: After the clothes dryer executes the drying mode for the first time, controlling the clothes dryer to obtain image information of the clothes;

[0042] Step S200: controlling the clothes dryer to compare the image information with the first preset image information;

[0043] Step S310: determining whether the image information is lower than the first preset image information;

[0044] Step S311: when the image information is lower than the first preset image information, controlling the clothes dryer to continue to execute the drying mode;

[0045] Step S320: when the image information is lower than the first preset image information, determining whether the image information is lower than the second preset image information;

[0046] Step S321: when the image information is lower than the second preset image information, controlling the clothes dryer to continue to perform the drying mode for the second time;

[0047] Step S322: when the image information is not lower than the second preset image information, controlling the clothes dryer to continue to perform the drying mode for the third time;

[0048] Step S312: When the image information is not lower than the first preset image information, the clothes dryer is controlled to stop drying.

[0049] Of course, the information stored in the dryer may also include second preset image information, which is smaller than the first preset image information. By comparing the image information of the clothes being dried with the first preset image information and the second preset image information stored in the dryer, the drying state of the clothes can be better judged, thereby better controlling the subsequent drying time of the clothes or the speed of the inner drum. In the following, the second preset image information is set as the boundary image information when the clothes are in a semi-dry state. When the clothes are in a relatively wet state, that is, the image information obtained is smaller than the second preset image information, the rotation speed of the inner drum can be increased or the rotation time of the inner drum can be increased at the same time to ensure that the clothes can be dried as soon as possible. When the clothes are in a semi-dry state, that is, the image information obtained is greater than or equal to the second preset image information and smaller than the first preset image information, the rotation speed of the inner drum can be reduced relative to the clothes being in a relatively wet state, thereby avoiding the situation where the clothes are clumped. When the clothes are completely dried, that is, the image information obtained is greater than or equal to the first preset image information, the dryer is controlled to stop drying. The above-mentioned control method for the drying state of the clothes and the corresponding rotation speed of the inner drum is not restrictive and can be set according to the needs of those skilled in the art.

[0050] like Figure 4 FIG. 4 is a third specific implementation of the control method of a clothes dryer based on multispectral imaging of the present invention, which specifically includes the following steps:

[0051] Step S100: After the clothes dryer executes the drying mode for the first time, controlling the clothes dryer to obtain image information of the clothes;

[0052] Step S200: controlling the clothes dryer to compare the image information with the first preset image information;

[0053] Step S300: selectively controlling the clothes dryer to continue to perform the drying mode or stop drying according to the comparison result;

[0054] Step S400: after selectively controlling the clothes dryer to continue to perform the drying mode or stop drying according to the comparison result, determining whether the dried clothes are clumped;

[0055] Step S410: When the dried clothes are judged to be clumped, the dryer is controlled to execute a shaking mode.

[0056] As the clothes dryer is drying clothes, the inner drum of the dryer will rotate, which may cause the clothes to clumping during the inner drum rotation, 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 setting seriously affects the user experience. In order to avoid the above situation, it is possible to detect whether the clothes in the dryer are clumping. The clothes clumping described in the present invention can be clothes entangled together or clothes wrapped together, or clothes stacked on each other. The above is not restrictive and can be set according to the needs of technicians in this field. The present invention can determine whether the clothes are clumped after the first drying mode is executed and the clothes have not been completely dried. 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 to determine whether the clothes are clumped. When the clothes are judged to be clumped, it is necessary to execute the shaking mode. 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. Of course, according to the needs of those skilled in the art, the present invention can determine whether the clothes are clumped after the first drying mode is executed and the clothes have been completely dried. At this time, it is only necessary to shake the clothes and no longer dry them. The above is not restrictive and can be set according to the needs of those skilled in the art.

[0057] The shaking-out mode may be to control the dryer to execute forward rotation for T2 time and reverse rotation for T3 time, the forward rotation and reverse rotation are executed n times respectively, and the forward rotation and reverse rotation are performed alternately. Since the dried clothes are likely to become tangled when the inner drum rotates continuously in one direction, it is necessary to control the inner drum of the dryer to rotate forwardly and reversely alternately. Since the dried clothes may form a ball when the inner drum of the dryer rotates in a certain direction, the balling phenomenon may be aggravated easily with the increase of rotation time. When the clothes are not completely dried, the inner layer of the balled dried clothes may be wet while the outer layer is dry. When the dried clothes have already formed a ball, alternating the forward rotation and reverse rotation of the inner drum may alleviate the above-mentioned balling phenomenon. After the clothes are 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 forwardly and reversely alternately, the inner drum may be controlled to rotate forwardly at a first speed for T2 time and reversely at a second speed for T3 time, thereby shaking out the clothes.

[0058] In summary, the multispectral camera can take pictures of the clothes in the dryer to obtain image information, and the image information includes RGB values ​​and / or near-infrared values. In the subsequent drying process of the clothes, the image information of the clothes is obtained by the multispectral camera and compared with the first preset image information stored in the dryer, so as to determine whether the clothes are completely dried at present, and then more accurately determine whether the dryer needs to stop running. The present invention can control the dryer to obtain the image information of the clothes in real time after the dryer executes the drying mode for the first time, and stop the operation of the dryer in time, thereby saving the power resources of the dryer. The image information can also be collected once at a certain time. The way of obtaining the image information of the clothes at a time interval of T1 can avoid the situation where the dryer is in real time to judge the image information and the corresponding first preset image information, thereby reducing the working time of the processing device of the dryer, and then delaying the service life of the processing device of the dryer. In addition, after the clothes are completely dried, in order to avoid the problem that the user forgets to take out the clothes and the clothes are placed in the dryer for too long, after the dryer stops drying, the dryer is controlled to execute the reminder mode to remind the user to take out the clothes. The information stored in the clothes dryer may also include second preset image information, which is smaller than the first preset image information. By comparing the image information of the clothes being dried with the first preset image information and the second preset image information stored in the clothes dryer, the drying state of the clothes can be better judged, and the subsequent drying time of the clothes or the speed of the inner drum can be better controlled. Since the clothes dryer is drying clothes, the inner drum of the dryer will rotate, 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, in order to reduce the occurrence of the above situation, it is possible to detect whether the clothes in the dryer are clumped.

[0059] 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.

[0060] 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.
