Description

The present invention relates to a washing machine for washing dishes, and more particularly to pre-wash washing.

When washing dishes in the kitchens of restaurants, employee cafeterias, etc., the used dishes are placed in a dedicated rack according to the type of dishes and put into the dishwasher. Such dishwashers have already been put into practical use.

In this dishwasher, tableware stored in a washing chamber is washed with washing water jetted from washing nozzles, and then rinsed with rinse water jetted from rinsing nozzles. The washing water is maintained at a temperature of around 65° C. to remove dirt adhering to the tableware. The rinsing water is maintained at a temperature of about 80-90° C. to rinse and sterilize the washed tableware as well as enhance the drying effect. Washing water is stored in a washing tank, sucked appropriately by a pump, and guided to a washing nozzle. The rinsing water is stored in the rinsing tank, sucked by a suitable pump and led to the rinsing nozzle.

However, if used dishes are washed as they are, dirt such as sauces and oily leftovers adhering to the dishes are brought into the washing machine, causing the following adverse effects.
1) (Deterioration of Cleaning Solution) Due to the oil contained in the dirt, the cleaning solution deteriorates, and the surface activity and emulsification cease to function in a short period of time.
2) (Clogging) When washing water is circulated and used, leftover food adheres to the suction part of the circulation pump, causing clogging and the circulation pump not functioning.
In order to prevent these harmful effects, pre-washing work is required. For example, prepare a tank filled with hot water and soak the dishes in advance to liquefy the leftovers. At present, they are put into the dishwasher after being washed.
