Example 1
Fig. 1 is a flowchart of a sterilization control method according to an embodiment of the present invention, and as shown in fig. 1, the method includes:
s101, judging whether the current time period is a daytime time period or a nighttime time period, monitoring the concentration of ozone in the refrigerator, executing step S102 if the current time period is the daytime time period, and executing step S103 if the current time period is the nighttime period.
The judgment of the current time period can be realized by a clock inside the refrigerator, and the 24-hour time period in one day can be divided into a daytime time period and a nighttime time period according to the work and rest habits of the user, for example, 5:00-24:00 is set as the daytime time period, and 0:00-5:00 is set as the nighttime period.
S102, controlling the on-off of the sterilizing device according to the ozone concentration in the refrigerator, for example, when the ozone concentration is higher than a certain value, closing the sterilizing device to reduce the release of ozone and reduce the ozone concentration, and when the ozone concentration is lower than the certain value and cannot cause harm to a human body, opening the sterilizing device to sterilize articles stored in the refrigerator.
S103, report to the police when ozone concentration in the refrigerator surpasses and predetermine the threshold value, period at night, according to normal work and rest habit, people have had a rest, the frequency of utilization greatly reduced of refrigerator, therefore, can not automatic control bacteria removing device' S switching this moment, only surpass and predetermine the threshold value at ozone concentration, when probably causing the injury to the human body, send out the police dispatch newspaper, if in this period, someone uses the refrigerator, can remind the user, ozone concentration in the refrigerator is too high, the user can manually close bacteria removing device, wherein, report to the police and can pass through modes such as demonstration ozone concentration information and warning mark, also can pass through sound prompt.
By the sterilization control method, different control schemes are adopted for the daytime period and the nighttime period, and the opening and closing of the sterilization device are controlled according to the concentration of ozone in the refrigerator in the daytime period; the time period at night, then report to the police when the ozone concentration in the refrigerator surpasss and predetermine the threshold value, can real-time detection and control ozone concentration, when avoiding the user to open the refrigerator, the ozone concentration in the refrigerator is too high, causes the injury to the user, promotes the security.

Specifically, if the ozone concentration is greater than or equal to the first threshold, it indicates that the ozone concentration in the refrigerator is too high at this time, and continues to rise, which may cause injury to the user, and therefore, the sterilization device needs to be triggered and controlled to be turned off to stop the generation of ozone, thereby reducing the ozone concentration in the refrigerator; if the ozone concentration is smaller than the first threshold and larger than the second threshold, the ozone concentration in the refrigerator is in a safe range, and then the sterilizing device is triggered and controlled to be kept in a current opening or closing state, so that the oxygen concentration is kept in the safe range; if the ozone concentration is less than or equal to the second threshold value and lasts for the first preset time, the ozone concentration in the refrigerator is very low at the moment, the human body cannot be injured even if the ozone concentration is continuously increased by a certain value, and the degerming device needs to be triggered and controlled to be started again in order to ensure the freshness of food in the refrigerator.
In this embodiment, in the night time, when the concentration of ozone in the refrigerator exceeds a preset threshold, an alarm is issued, wherein the preset threshold may be equal to or unequal to the first threshold, and the preset threshold is set according to actual needs, which is not specifically limited in the present invention.
After triggering control the degerming device and reopening, can produce ozone, make the ozone concentration in the refrigerator rise, in order to continue to guarantee that the ozone concentration in the refrigerator does not exceed the safety range, after the second preset time, need again according to the opening and closing of the ozone concentration control degerming device in the refrigerator.
Since it is necessary to trigger the corresponding operation according to the concentration of ozone in the refrigerator regardless of the daytime or nighttime period, in some embodiments, monitoring the concentration of ozone in the refrigerator includes: the ozone concentration in the refrigerator is detected by an ozone detector.
