Preferably, the water delivery pipe 36 is a flexible pipe, which can better adapt to the rotation of the connecting portion 32 and the swing of the first swing arm 33 and the second swing arm 34.

[0062] In this embodiment, two first spray arm assemblies 3 are provided. The two first spray arm assemblies 3 are respectively arranged on two side walls of the inner tank 1 to spray and wash the dirt on the tableware facing the side walls. It should be noted here that when placing the tableware, the dirt on the tableware needs to face the two side walls of the inner tank 1, which is more conducive to the first spray arm assembly 3 located on the side walls of the inner tank 1 to clean the dirt on the tableware.

[0063] Of course, the setting of the first spray arm assembly 3 is not limited to the above manner. As an alternative embodiment, three first spray arm assemblies 3 can also be provided, which can be arranged along the two side walls and the rear wall of the inner tank 1.

[0068] In some embodiments, the dishwasher further includes a second spray arm 35 assembly disposed at the top of the inner container 1 for comprehensively cleaning tableware.

[0069] The second spray arm 35 assembly disposed at the top of the inner container 1 is activated after the first spray arm assembly 3 finishes cleaning, and is used to comprehensively clean all the placed tableware. That is to say, in this application, the first spray arm assembly 3 is first used to perform fixed-point and precise cleaning on the dirt on the tableware, and then the second spray arm 35 assembly is used to perform comprehensive coverage cleaning on all the tableware, thereby achieving the cleaning effect on the tableware while saving water resources.

[0070] The second spray arm 35 assembly is a prior art in the field of dishwashers, and will not be elaborated in this embodiment.

[0071] As Figure 5 shown, according to an embodiment of the present invention, on the other hand, a control method of a dishwasher is disclosed, and the control method includes: According to the dishwasher entering the intelligent cleaning mode, obtain the dirt position of the tableware; Determine the running track and spraying angle of the first spray arm assembly 3 according to the dirt position of the tableware; Control the operation of the first spray arm assembly 3 according to the determined running track and spraying angle to perform fixed-point cleaning on the dirt on the tableware.

[0072] The control method of the present invention is used to control the dishwasher of the present invention. Therefore, this control method has the same technical effects as the dishwasher of the present invention. For details, please refer to the above description and will not be elaborated here.

[0073] Specifically, the dirt condition of the tableware can be photographed by the first camera 21, the second camera 22, and the third camera 23 provided on the dishwasher, and then the photographed data is transmitted to the controller. The controller uses AI image recognition technology, combined with the angles of each camera during shooting, to determine the dirt position on the tableware. Finally, the optimal running track and spraying angle of the first spray arm assembly 3 are planned by the AI algorithm according to the dirt position.

[0074] As Figure 6 shown, in some embodiments, the tableware has at least two dirt spots. Controlling the operation of the first spray arm assembly 3 according to the determined running track and spraying angle includes: Control the first spray arm assembly 3 to run corresponding to one of the dirt spots; Judge whether the cleaning of one of the dirt spots by the first spray arm assembly 3 meets the standard; If so, control the first spray arm assembly 3 to operate corresponding to the next piece of dirt for cleaning until all the dirt on the tableware is removed.

[0075] Control the first spray arm assembly 3 to operate corresponding to one of the dirt, so as to achieve precise cleaning of the dirt at that place. During the cleaning process, it is judged whether the cleaning of the dirt at one place by the first spray arm assembly 3 meets the standard. If so, it means that the cleaning of the dirt at one place has been completed, then control the first spray arm assembly 3 to operate corresponding to the next piece of dirt for cleaning until all the dirt on the tableware is removed, so that the first spray arm assembly 3 can automatically adjust the operation path and posture according to the cleaning situation and the position of the dirt on the tableware, achieving the effect of automatic dirt search and cleaning.

[0076] As Figure 7 shown, in some embodiments, judging whether the cleaning of the dirt at one place by the first spray arm assembly 3 meets the standard includes: Obtain the real-time picture of the tableware during the cleaning process; Compare the real-time picture of the tableware with the picture recorded at the previous moment; Judge whether the color similarity of the dirt at the same position in the real-time picture and the picture recorded at the previous moment is higher than the preset value.

[0077] By comparing the obtained real-time picture of the tableware with the picture recorded at the previous moment, judge whether the color similarity of the dirt at the same position in the real-time picture and the picture recorded at the previous moment is higher than the preset value. If so, it means that the cleaning of the dirt at one place by the first spray arm assembly 3 has met the standard, and the first spray arm assembly 3 can be controlled to operate to the next piece of dirt.

[0078] It should be noted here that the color of the position with dirt on the tableware is darker. As the first spray arm assembly 3 cleans the dirt, the color of the dirt position gradually becomes lighter. When the dirt is basically completely removed, the color at the dirt position no longer changes significantly. Therefore, by judging whether the color similarity of the dirt at the same position in the real-time picture and the picture recorded at the previous moment is higher than the preset value, it can be judged whether the cleaning of the dirt meets the standard.

[0079] In some embodiments, the preset value is 95%.

[0080] By setting the preset value to 95%, when it is judged that the color similarity of the dirt at the same position in the real-time picture and the picture recorded at the previous moment is higher than 95%, it can be concluded that the cleaning of the dirt at one place has met the standard.
