Description

Residue crushing device, dish washing machine and residue crushing method for dish washing machine

Technical Field

The invention relates to the technical field of kitchen electricity, in particular to a residue crushing device, a dish washing machine and a residue crushing method for the dish washing machine.

Background

In the related art, most of the dishwasher residue treatment mechanisms mostly use a structure similar to a soymilk grinder for crushing food to treat food residues, or use a shearing force formed by coaxial forward and reverse rotating double knives to shear the residues, or use a multi-stage crushing structure similar to a garbage disposer for crushing the residues.

However, the dishwasher using the above-mentioned residue treatment structure has insufficient treatment capability for tough food residues, which is often expressed in that the cutter has contacted the food residues, but cannot completely crush the tough residues due to insufficient instantaneous impact force, and the cutter has selectivity for crushing the types of the residues.

The residue was not subjected to multistage treatment. The existing scheme treats the residues through a single treatment structure, and has the main defects that the residues cannot be smashed in a comprehensive mode, part of the residues can only pass through an action area of the treatment structure once and cannot return to a cutter action area again, so that the probability of smashing the residues is reduced, the smashing degree of the residues is reduced, the residues enter a drainage system in an incompletely smashed state, and the drainage system is prone to being blocked.

The existing dishwasher structure cannot ensure the fineness of the discharged particles. Because the great discharge of fixed filter screen restriction after the residue is smashed to current dish washer, prevent that drainage system from blockking up, simultaneously because it is great to filter the filter screen aperture, to the residue of bar, as long as one end can pass filter hole alright get into the filter screen through the filter screen, can not effectively prevent drainage system jam problem.
