Tableware that can't withstand high temperature, such as plastic, can't be put in the high-temperature disinfection cabinet below, but should be put in the low-temperature disinfection cabinet above to avoid damaging the tableware. The common sense of daily disinfection cabinet should be that tableware should be washed and drained before being put into disinfection cabinet, which can shorten disinfection time and reduce power consumption. When using ozone disinfection cabinet, pay attention to whether the ozone generator works normally. Anyone who can't hear the squeak of high-voltage discharge or see the blue light of discharge indicates that the ozone generator may be out of order and should be repaired in time.
