The temperature resistance of the whole dishwasher lamp will not exceed 250 ℃. In medical disinfection, the general disinfection of dishwashers can kill viruses such as Escherichia coli with water temperature of 70 °C. Excessive temperature not only does not help the washing effect, but also makes some tableware deformed with poor temperature resistance under high temperature. Thereby releasing toxic substances. It is reasonable that the dishwasher lamp can achieve a temperature resistance of >100 °C.
