Description

Technical Field

[0001] The invention relates to a dish scrubber and a working method thereof. Background Art

[0002] Traditional dishwashing methods are basically manual, which is not only time-consuming, but also very troublesome. In some large restaurants, there are thousands of dishes to be washed after the guests finish their meals. If they are all washed manually, it will not only take a lot of time, but also be very hard and labor-intensive. Most dishwashing machines are imported from abroad, but there is a big difference between foreign and domestic eating patterns. China has a variety of cooking methods for food, and oil is an indispensable cooking ingredient, so it is inevitable that there are many difficult-to-wash oil stains on the dishes, while Western cooking methods are relatively simple, mostly eating salads and hamburgers, and there are fewer oil stains left on the dishes; secondly, mainstream washing machines are all running water or ultrasonic, requiring special detergents. Such washing methods cannot remove the difficult-to-remove oil stains on the dishes to be washed, and cannot eliminate the general concern of Chinese consumers that they cannot be cleaned without washing.

The washing mechanism comprises two washing discs 220 with different rotation speeds for clamping the dishes. The washing mechanism uses two washing discs with the same rotation direction but different rotation speeds to wash the dishes, which can prevent the dishes from rotating synchronously with the washing discs. The two washing discs wash the two sides of the dishes respectively. The dish washer 200 is opened at the bottom to form a discharge port. The dish washer is placed in a sink, and the dishes are manually put into the dish washer. After being washed by the washing mechanisms on both sides, the dishes fall from the discharge port at the bottom of the washing box. The dish washer can reduce labor consumption, making the dish washing process simpler and easier, and can also make the dishes cleaner by washing the upper and lower washing plates, thereby realizing the mechanization of dish washing. The machine replaces manual work, thereby reducing the fatigue of workers and improving the work efficiency of dish washing.

[0022] In this embodiment, a sponge body 300 located below the washing box is installed at the lower part of the frame 100, and a quarter-circular arc-shaped material guide slope 310 located below the discharge port is opened on the sponge body 300.
