Description

Sewer breaker for sink dish washer

Technical Field

The invention relates to the technical field of sink dish washers, in particular to a drain breaker for a sink dish washer bowl.

Background

The sink dish washer is a novel household appliance generated in the development process of modern kitchens. The dish washer is integrated in the water tank, so that automatic washing of dishes and the like is realized, the labor intensity of washing the dishes in household labor is greatly reduced, and convenience is brought to users. However, due to the fact that the water tank dish washer has the factors of high temperature, cleaning agent, water vapor, ultrasonic waves and the like in the cleaning process, the closed type cleaning is achieved by the cover panel, the drainer is blocked when food on dishes to be cleaned is doped more, people cannot find and clean the dishes in time at the moment, the water tank dish washer is stopped due to the blocking of the sewer, user experience is affected, and the water tank dish washer is damaged due to abnormal stopping. If the user removes most food residues on the dishes in advance before putting the dishes into the sink dishwasher, although the problem of drain blockage can be greatly reduced, the labor intensity of the user is obviously increased, and the convenience of the sink dishwasher cannot be represented. And for food residues such as caramel food which are partially adhered to the dishes, the food residues are difficult to remove by dumping, so that the labor intensity of cleaning before putting the dishes into the sink dish washer is further increased, and the tedious pre-cleaning process obviously cannot reflect the convenience brought by the sink dish washer instead of personnel cleaning.
