WASHING AND DISINFECTING DEVICE, WASHING AND DISINFECTING SYSTEM, AND DEVICE AND METHOD OF DETERMINING WATER SUPPLY ABNORMALITY OF WASHING AND DISINFECTING DEVICE

摘要

PROBLEM TO BE SOLVED: To accurately determine water supply abnormality due to clogging of a water filter even in the case that, while a washing and disinfecting device is executing water supply, another washing and disinfecting device sharing water facilities supplies water simultaneously.;SOLUTION: The washing and disinfecting device measures the water supply time T from the start of the water supply to the time when a water level reaches a predetermined water level. Water supply status information indicating the water supply execution situation of another washing and disinfecting device which has supplied water simultaneously within the water supply time is acquired. On the basis of the water supply status information, an independent time ratio of independent execution and an execution time ratio for each number of devices that have executed the water supply simultaneously in the water supply time T are obtained. An independent execution water supply time coefficient and a simultaneous execution water supply time coefficient for each number of devices obtained beforehand are weighted by the independent execution time ratio and the execution time ratio for each number of devices, and the weighted average α of the water supply time coefficient is obtained. By dividing the water supply time T by the weighted average, a delay portion due to simultaneous execution is removed from the water supply time T, and an evaluation value indicating delay due to clogging is calculated.;COPYRIGHT: (C)2012,JPO&INPIT
