This is really an indication of the deterioration of the food. The foods with peculiar smell not only affect appetite, but also have great influence on health if being eaten for a long time. Accordingly, technologies such as ion sterilization are widely applied to refrigerators. An ion generator in a refrigerator generates a large amount of negative ions under a high pressure condition, but at the same time, ozone, a derivative thereof, is generated, and both of them adsorb various viruses and bacteria to cause structural change or energy transfer, resulting in death thereof. However, the prior ionizer has a single control method and does not achieve a good sterilization effect.
Meanwhile, the user can generate odor by reflecting the fact that the concentration of derivative ozone generated by the ionizer is too high, and the ozone concentration can stimulate the respiratory tract of a human body to cause sore throat, chest distress and cough, bronchitis and emphysema; can cause nerve poisoning, headache, dizziness, visual deterioration, hypomnesis and shortness of breath; destroying vitamin E in skin, causing skin wrinkle and black spot; ozone can also destroy human immune function, induce chromosome disease of lymphocyte, accelerate aging, and cause pregnant women to have malformation.

For example: setting the sterilization time length to be 0.5h, and forcibly operating the ion generator for 0.5h when a refrigeration request is made in the compartment under the condition that the opening of the compartment is not detected until the next sterilization control period, thereby circulating. When the compartment has no refrigeration requirement, that is, the temperature of the compartment is less than or equal to the set temperature, the sterilization device is controlled to start the sterilization duration within the set sterilization duration range before the end of a sterilization control period, for example, one sterilization control period is 12 hours, the set sterilization duration is 0.5h, and if the opening of the compartment is not detected and no refrigeration request is made in the first 11.5h of the sterilization control period, the sterilization device is forcibly started in the last 0.5 h.

If the refrigerator is not powered on for the first time after leaving the factory, the sterilizing device is powered on for the third time period when the refrigerator is powered on. Because the refrigerator is powered on for the first time, no food exists in the refrigerator, and the condition of quick propagation of bacteria can not be met for 24 hours even if the food exists in the refrigerator, the power can be saved by postponing the starting of the sterilizing device. If the refrigerator is not powered on for the first time and is possibly started after the refrigerator is powered off, articles are generally stored in the refrigerator, and therefore the sterilization device is controlled to start sterilization while the refrigerator is not powered on for the first time.
