Description

Technical Field

[0001] The invention belongs to the field of kitchen equipment, and in particular relates to a spray cleaning system based on magnetic suspension technology. Background Art

[0002] Washing dishes is a necessary procedure after a meal, but usually people don’t like it. Later, the emergence of dishwashers helped people solve the family conflict of who should wash the dishes to a certain extent.

[0003] Early dishwashers were not ideal, had poor cleaning effects, and had complex structures that made cleaning difficult. For example, some dishwashers used the motor's rotating shaft to directly penetrate the inner cavity of the dishwasher, and the inner cavity was also equipped with a rotary spray arm. However, this structure often could not be disassembled and cleaned, or was very troublesome to disassemble and clean. After years of use, secondary pollution was caused because the dishwasher itself was not clean.

[0004] Dishwashers first became popular in Europe and the United States, but due to their dietary habits, their food is relatively simple and plain, and the specifications of tableware are relatively simple (mainly plates). After European and American families finish their meals, the plates are not seriously stained by food and are very easy to clean. Therefore, dishwashers with simple cleaning effects can meet the needs of most European and American families, and the monotonous tableware specifications are also easy to clean by machine. However, this set is not suitable for Chinese food.

[0005] Chinese cuisine emphasizes diversity in cooking, including frying, steaming, slow cooking, baking, salting, etc., a wide variety of cooking techniques. Chinese food is also diverse, and Chinese bowls and utensils come in all sizes. The "contamination" of tableware by heavy oil and sticky food residues is very stubborn, which is a huge difference from Western food. The dishwashers popular in Europe and the United States are completely unsuitable for Chinese families.

[0006] Chinese families have higher requirements for the cleaning ability of dishwashers than Western families. In addition to higher cleaning ability requirements, Chinese food residue is more difficult to remove, and the "pollution" to the dishwasher itself is also very serious. The residue left in the sanitary dead corners will quickly and easily breed bacteria. Therefore, the daily cleaning and maintenance of Chinese dishwashers is also a very important part. If it is not done well, it will cause secondary and more serious pollution, posing greater hygiene and health risks. Summary of the invention

When the spray is working, the intelligent control water discharge unit 55 closes the water discharge port 121 of the spray tank 1. After the water is sprayed out by the spray rotating unit 8, it falls back to the water filter area 19, enters the water pump area 18 through the three-way pipe 124, and is sprayed out again by the spray rotating unit 8, so that the water is recycled, which is more water-saving than traditional cleaning. After the spraying work is finished, the cleaned items can be taken out, the bowl basket rack can be taken out, and then the entire spray rotating unit 8 can be removed. At this time, there is no other sanitary dead corner at the bottom of the spray tank except the drain, which is very convenient for routine maintenance and cleaning of the spray tank 1, and the removed spray rotating unit 8 is also easy to clean.

[0124] The spray cleaning system of the present embodiment can also utilize the timing function, and utilize the intelligent touch system to control the spray cleaning system to start the spray cleaning program at a fixed time. For example, the spray cleaning system can be controlled to start the spray cleaning program between 1 a.m. and 3 a.m. every day, and can also be controlled to automatically spray and flush once every 5 hours. In this way, the spray tank 1 can be used as a storage space, and bowls and the like can be stored therein for a long time, which is convenient for daily life.
