[0045] The bowl rotating rack 81 and the dish rotating rack 82 are connected to the motor 89 via a connecting rod or a transmission belt 88, and are driven by the motor 89 to synchronize the bowl rotating rack 81 and the dish rotating rack 82. Of course, the connection can also be switched separately as needed.

[0046] The cup basket 11 is made of metal or plastic strips and is located above the bowl slot 7 and between the upper spray arm 121 and the lower spray arm 122. The chopstick basket 10 and cup basket 11 are respectively provided with hanging buckles 101 and 111. The chopstick basket is located above the dish slot and below the upper spray arm.

[0047] Summarizing the above and combining all the figures, the workflow is further described:

[0048] First, connect the water supply and power, add detergent, press the top cover lock button with your finger, and pull it toward the front panel 2 to remove the top cover 4. Place the dishes in the dish slot 6 and insert them into the dish positioning clips. Place the bowls in the bowl slot 7 and insert them into the bowl positioning clips. Place the cups with the cups facing down and flat on the cup basket. Place the chopsticks in the chopstick basket. After placing all the dishes, insert the top cover snap-in end into the panel snap-in slot. Press the other end of the top cover 4 down, inserting the locking tongue 42 of the front panel 2 into the locking tongue slot 34 of the back panel. Now, start washing. The dish rack brush motor 89 begins to rotate clockwise. When the dish rack cross arm reaches the dish and bowl positioning clips, it switches to counterclockwise rotation. When the dish rack cross arm reaches the other side of the dish and bowl positioning clips, it switches back to clockwise rotation, and so on. Motor 89 drives the dish rack 82 and bowl rack 81 to rotate back and forth around the rotating shaft via a connecting rod or transmission rod and a belt, respectively. The dish rack 82 and bowl rack 81 can be made of metal or plastic. They are arched in shape, with positioning teeth 86 on the crossbars, allowing the bowl brush 84 and dish brush 85 to be positioned anywhere on the crossbars. The rotation of the dish racks 82 and 81 simultaneously drives the brushes mounted on the dish brushes 84 and 85 to rotate radially. This rotation creates friction with the surfaces of the dishes and bowls, removing any dirt that adheres to them. The brushes can be made of metal or plastic, with bristles arranged in a 360-degree radial pattern. Adjacent brushes sandwich the dishes or bowls, supporting them in a row while simultaneously scrubbing both sides. The brushes are secured to the racks with a lock, allowing the brush position to be adjusted to suit the size of the dishes or bowls, and the brush shape can be adjusted to suit butterfly or bowl shapes. The shapes of the dish brushes are illustrative only; select a brush that ensures full contact with all surfaces of the dishes or bowls.

[0049] The bottom of the inner chamber features two curved grooves, one for plates and the other for bowls. The arc of the grooves matches the rotational arc of the bowl and dish racks. This curved design helps collect wash water, which then rotates as the dish brush rack distributes it to all parts of the dishes and bowls, reducing the need for spray water. The two curved grooves are connected by a connecting groove. Cups are held in the basket, and spray arms are positioned above and below the basket. These arms rotate 360 ​​degrees while spraying high-speed water jets, either directly or deflected, onto all surfaces inside and outside the cups, removing stains from the cups.

[0050] A dish brush 85 has a protruding scraping lug 80 at one end. As the brush rotates, it repeatedly scrapes the chopsticks. The chopstick basket has a circular arc bottom. The scraping lugs cause the chopsticks to flip and rub against each other within the basket. Combined with the impact of the water sprayed from the spray arm, the scraping lugs 80 are made of soft metal or plastic.

[0051] After the washing process is completed, the dishwashing water is discharged by the drain pump 128. After the washing water is drained, new tap water is injected into the spray system through the circulating water motor, and the bowl brush 84 and the dish brush 85 start rotating and rinse with clean water. The rinsing process is similar to the washing process.

[0052] Heated water can be used for both washing and rinsing. When hot water is needed, the heating component 125 starts heating under instruction and automatically stops heating when the set temperature is reached.

[0053] After washing and rinsing, you can choose to dry the dishes. When the drying function is activated, the fan in the dehumidification unit 15 operates, drawing air from the inlet. The moisture in the air is converted into condensed water by the electronic evaporator 153 and then discharged. This air is repeatedly circulated within the closed chamber, and the moisture in the air is continuously converted into condensed water and discharged, achieving the purpose of drying the dishes. Automatic dehumidification can keep the chamber dry for a long time, preventing mold and mildew.

[0054] For illustrative purposes, the foregoing description uses specific nomenclature to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that specific details are not required in order to practice the embodiments. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described above, and that improvements and substitutions based on the present invention using techniques known in the art fall within the scope of the present invention and are defined by the claims.
