Description

Control system of DC food waste disposer Technical field

The invention relates to the technical field of a direct current food waste disposer, in particular to a control system of a direct current food waste disposer.

Background technique

The food waste disposer is a small electrical appliance installed at the drain of the kitchen sink. It provides a brand new method to dispose of food waste in modern households. The food waste disposer is installed under the kitchen sink and works with The drainage pipe is connected, and the food waste can be treated in a timely manner by changing the shape of the food waste. The food waste can be crushed into a slurry liquid and discharged directly from the sewer pipe, which can easily realize instant, convenient and fast kitchen cleaning. To prevent food waste from breeding bacteria, mosquitoes and odors due to storage, it effectively optimizes the home environment and completely solves the problem of easy clogging of sewers. The core component of the food waste disposer is the grinder, which is made of stainless steel and is processed by high-speed rotation of the electrode. Garbage, rubbish is ground into very small particles, which are easily washed away by water. Therefore, it is generally installed in the lower part of the kitchen sink and is mostly cylindrical. With this kind of food waste disposer, all residual waste is ground and crushed. It is flushed away through the sewer, which is very hygienic and convenient.
