Dishwashing system based on loofahs

摘要

This article presents a design scheme for a dishwashing system based on loofahs and develops a prototype. The dishwashing system contains seven parts: the transceiver device, the slag removing device, the main cleaning device, flushing device, the drying and the sterilizing device, the water supply and drainage device and the monitoring interface. We use PLC timing to control the transceiver device, which can save labor and reduce costs. The slag removing device cleans the dishes roughly using loofah brush heads. The main cleaning device contains a rotary cleaning part and a conveying cleaning part. Both of them are easy to disassemble and update; the PLC module controls the block cylinder to fix the dish, and then the conveyor belt drives the loofah cleaning belt to clean the bottom of dish, at the mean time the loofah brush head cleans the groove of dish. The flushing device rinses dishes with tap water. The drying and sterilizing device consists of a turnover part, a water absorption part and a heat drying part. Finally, we can get dry and sterile dishes. The water supply and drainage device comprises a sewage pipe, a water circulation pipe and a waste heat utilization pipeline, and it realizes the water circulation of the whole dishwashing system. The monitoring interface ensures the cleaning effect of the dishwashing system. Compared with the traditional dishwashers, the dishwashing system in this paper has remarkable energy-saving and emission reduction effects, along with great market space and promotion value at the same time.
