Description

Automatic dishwasher that detects an operation error and stops the operation {AUTOMATIC DISHWASHER WHICH ENABLES TO STOP OPERATION BY DETECTING OPERATION ERROR}

The present invention relates to an automatic dishwasher that detects an operation error and stops the operation in order to prevent malfunction.

In the case of large-scale restaurants that are used by a large number of people at the same time, such as schools, cafeterias, and buffets, most use dishes such as bowls, plates, or plates with a fixed size or shape.

When washing these dishes, primary washing is performed to remove food debris adhering to the plate. In this initial cleaning, the plate with food residues is placed in a large container with detergent dissolved in it, soaked in the food residues, and then the cleaner holds the brush with one hand and the plate with the other hand, then grinds the upper and lower surfaces of the plate with the brush alternately. This was done by wiping and separating the food residues attached to the plate. However, in the above method, it is possible to clean the plate in tens of units, but in case of primary washing more than hundreds of plates, the washing operation is repeated due to repeated washing. A lot of strain was applied to the arms and legs, which eventually caused arthritis back and muscle pain.

Accordingly, a plate washing machine that automatically wipes the plate has been developed (Patent No. 10-1129371).

However, the plate washer as above was able to wash only the plate of the same type, and therefore the plate was not caught in the transport part during the transport process.

But, not just a plate, but a concave bowl. In the case of washing a circular oval plate, since these shapes are varied, a phenomenon in which the tableware gets stuck in the transfer part has occurred. If the washing machine continues to operate even when the dishes are inserted into the transport part of the automatic dishwasher, an overload occurs on the motor or the transport assembly, resulting in malfunction.

An object of the present invention is to improve the durability of an automatic dish washing machine by detecting an operation error due to various causes during dish washing and stopping the dish washing operation accordingly.

According to an embodiment of the present invention, which has been devised to solve the above-described problems, an automatic dishwasher for stopping an operation by detecting an operation error includes a first body, a second body, and a third body, and detects an operation error.
