[0032] The preferred embodiments of the present application will be described below in conjunction with the accompanying drawings, in which:

[0033] It should be noted that, in the description of the present application, the terms indicating the direction or position relationship such as "upper", "lower", "inner", "outer" and the like are based on the direction or position relationship shown in the drawings, which is merely for the convenience of description, and does not indicate or imply that the related devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the ordinal numbers "first", "second" and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0034] In the description of the present application, "module", "processor" can include hardware, software or a combination of both. One module can include hardware circuit, various suitable sensors, communication port, memory, and can also include software part such as program code, and can be a combination of software and hardware. The term "A and / or B" means all possible combinations of A and B, such as only A, only B or A and B. The term "at least one of A or B" or "at least one of A and B" has a similar meaning as "A and / or B", which can include only A, only B or A and B.

[0035] First of all, it needs to be pointed out that the laundry washing machine in the application is provided with an image acquisition module and a spraying device. Among them, the image acquisition module is installed above the inner side of the drum door of the washing machine, and is used to acquire the image information of the inner side of the drum door. The spraying device can be installed above the inner side of the drum door of the washing machine or around the inner side wall of the drum door according to actual needs, as long as it can realize spraying and flushing the inner side area of the drum door, and the specific installation position and structure form of the application are not limited.

[0036] Referring to Figure 1 A condensation bead washing control method of a washing machine is disclosed in the application, which comprises the following steps:

[0037] S101: acquiring the image information of the inner side of the drum door of the washing machine through the image acquisition module.

[0038] In step S101, when the washing machine is in a powered-on state, the image acquisition module is in a running state, the state of the inner side of the drum door is monitored in real time, and the image information can be sent to the cloud server.

[0039] S102: judging whether the inner side of the drum door of the washing machine is adhered with washing condensation beads based on the image information, and selectively controlling the spraying device to flush the drum according to the judgment result.

[0040] In step S102, the cloud server judges whether there are washing machine condensation beads on the inner side of the drum door according to the image information. For example, the image information includes a plurality of image pictures, the cloud server compares each acquired image picture with the image pictures stored in it, and thus obtains a judgment result. When it is judged that the inner side of the drum door is adhered with washing condensation beads, the washing machine control system controls the spraying device to flush the drum. When it is judged that the inner side of the drum door is not adhered with washing condensation beads, the washing machine normally performs the washing process.

[0041] The application acquires the image information of the inner side of the drum door of the washing machine in real time through the image acquisition module. When the condensation beads are thrown out by the drum and adhered to the drum door, the spraying device is controlled to flush the condensation beads on the drum door, so that the condensation beads are flushed into the drum, and thus the condensation beads can be fully dissolved in the drum, ensuring the washing effect.

[0042] Referring to Figure 2 In an implementation manner, the above image information is divided into a first image picture and a second image picture. The first image picture is a picture in which the inner side of the drum door is not adhered with condensation beads, and the second image picture is a picture in which the inner side of the drum door is adhered with condensation beads. Then, step S102 specifically comprises:

[0043] S1021: when the image information is the first image picture, it is determined that the inner side of the drum door of the washing machine is not adhered with washing condensation beads, and the washing machine is controlled to run in a normal washing program.

[0044] S1022: When the image information is the second image frame, it is determined that the lint trap of the washing machine has the condensation bead adhered to the inner side, and the spraying device is controlled to flush the lint trap.

[0045] It should be noted that the cloud server stores a preset image, which is an image of the inner side of the lint trap without condensation beads. Therefore, in each frame of image acquired by the image acquisition module in real time, the image of the inner side of the lint trap without condensation beads adhered thereto corresponds to the first image frame, and when the inner side of the lint trap adheres to the condensation beads, the image acquired by the image acquisition module is different from the first image frame, that is, the second image frame. The image acquisition module acquires image information and compares it with the preset image in the cloud server. When the image frame is the same as the preset image, it is determined to be the first image frame, and when the image frame is different from the preset image, it is determined to be the second image frame.

[0046] Reference Figure 3 In an implementation manner, in step S102, when the spraying device is controlled to flush the lint trap, the following steps are further included:

[0047] S103: Determine whether the second image frame changes within a set time.

[0048] S104: Control the spraying device to flush the lint trap for a preset time according to the determination result.

[0049] In the above step S103, the set time can be determined according to actual needs. For example, the set time can be 1 second. Similarly, in step S104, the preset time can be 2 seconds, 3 seconds, etc.

[0050] It should be further noted that in step S103, the change of the second image frame indicates that the condensation bead is broken, that is, the size changes, or the position of the condensation bead moves, when the spraying device flushes the condensation bead. The second image frame does not change, which indicates that the condensation bead is not broken, that is, the size does not change, and the position of the condensation bead does not move, and the condensation bead still maintains the original shape.

[0051] Further, according to whether the second image frame changes, the preset time is divided into a first preset time and a second preset time. The change of the second image frame refers to the change of the size and / or position of the condensation bead patch in the second image frame; the second image frame does not change refers to the size and / or position of the condensation bead patch in the second image frame does not change. Then step S104 specifically includes:

[0052] S1041: If the size and / or position of the condensation bead patch in the second image frame changes within the set time, the spraying device is controlled to flush the lint trap for a first preset time.

[0053] S1042: If the size and / or position of the condensation spot in the second image frame does not change within a set time, control the spraying device to flush the drum door for a second preset time length.

[0054] It should be noted that in the step S1041, the size and / or position of the condensation spot changes within a set time, which indicates that the state of the condensation has changed, the condensation has been broken or moved, that is, the preliminary flushing effect has been achieved, and the flushing for the first preset time length is ended. In the step S1042, the size and / or position of the condensation spot does not change within a set time, which indicates that the condensation keeps the original form, the adhesion between the condensation and the drum door is large, and the preliminary flushing effect has not been achieved, and the flushing for the second preset time length is performed. It can be understood that the state of the condensation does not change, which indicates that the time for flushing the condensation should be lengthened to ensure that the spraying liquid can flush to the position of the condensation, or the duration of the flushing force of the spraying liquid is lengthened to enable the spraying liquid to break the condensation or move the condensation until it slides into the drum of the washing machine. Therefore, in order to ensure the flushing effect, the second preset time length is greater than the first preset time length.

[0055] The specific values of the first preset time length and the second preset time length are determined according to actual conditions. For example, the first preset time length is 3-5 seconds, and the second preset time length is 1-3 seconds.

[0056] In some possible implementations of the present application, in the step S102, the step of controlling the spraying device to flush the drum door can include the following two modes:

[0057] Firstly, the spraying device is controlled to continuously flush the drum door, that is, the spraying device is controlled to continuously operate within a preset time period.

[0058] Secondly, the spraying device is controlled to pulse flush the drum door, that is, the spraying device is controlled to intermittently operate within a preset time period, for example, the spraying device is controlled to operate for 2 seconds and then stop for 1 second, and then operate for 2 seconds again, and so on. The pulse flushing can improve the flushing effect to a certain extent.

[0059] The present application also discloses a control device of a washing machine, which includes a processor and a storage device. The storage device is adapted to store a plurality of program codes. The program codes are adapted to be loaded and run by the processor to perform the control method in any of the above embodiments.

[0060] It should be noted that the above processor can be a central processor, a microprocessor, a digital signal processor or any other suitable processor, which can be implemented in a software manner, a hardware manner or a combination of both, and the adjustment of the form and application level of the processor does not deviate from the principles and scope of the present application.

[0061] Similarly, the storage device described above can be any suitable medium that can store program codes, such as a hard disk, a flash memory, a read-only memory, a random access memory, and the like, and the present application does not make any limitation on the form thereof.

[0062] So far, the technical solution of the present application has been described in combination with the preferred embodiments shown in the drawings, but it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments. Those skilled in the art can make equivalent changes or replacements to the related technical features without departing from the principles of the present application, and the technical solutions after these changes or replacements will all fall within the protection scope of the present application.
