Description

Technical Field

[0001] The present invention belongs to the technical field of kitchen appliances, and relates to a dishwasher, in particular to a dishwasher slag and water circulation integrated system and an operation method thereof. Background Art

[0002] Dishwashers are used to automatically wash dishes such as bowls, chopsticks, plates, dishes, knives, forks, etc. They can be divided into two categories according to their structure: box-type and conveyor-type. They reduce the labor intensity of cooks in restaurants, hotels, and canteens of government agencies, improve work efficiency, and promote cleanliness and hygiene. Now, many small dishwashers have been launched on the market and are gradually entering ordinary households.

[0003] The washing pump is an important component of the dishwasher. Currently, the washing pumps of dishwashers on the market are all placed axially horizontally. This method will cause residual water to form in the pump casing after washing. After being left for a long time, it will deteriorate and have an odor, affecting performance and user experience.

[0004] Currently, dishwashers on the market require that larger residues on tableware be cleaned before they can be put into the dishwasher for washing. Otherwise, the residues are likely to remain at the bottom of the dishwasher, affecting water reflux and washing effects, and the operation process is complicated and inconvenient.

[0005] Currently, most dishwasher residue disposal methods on the market are to collect the residue in a filter basket, which is then removed after washing, cleaned, and then put back into the dishwasher. This operation is troublesome, and if not cleaned in time, the residue will deteriorate and easily cause secondary pollution.

[0006] The residue filters of dishwashers currently on the market have poor ability to resist foreign matter. If foreign matter enters the water cup, there will be risks such as impeller damage and spray arm clogging, affecting the performance and experience of the dishwasher. Summary of the invention
