Example 1
The embodiment provides a sterilization control method for improving safety, and fig. 1 is a flowchart of the sterilization control method according to an embodiment of the invention, as shown in fig. 1, and the method includes:
s101, judging that the current time period is a daytime time period or a nighttime time period, monitoring the ozone concentration 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 time period.
The judging of the current time period can be achieved through a clock in the refrigerator, 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 a user, for example, 5:00-24:00 is set as the daytime time period, and 0:00-5:00 is set as the nighttime time period, and it is noted that the invention only provides an example of a setting mode of the daytime time period and the nighttime time period, and the user can set the daytime time period and the nighttime period according to actual conditions.
S102, controlling the opening and closing 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 a certain value, the sterilizing device is opened to perform sterilizing treatment on articles stored in the refrigerator.
S103, alarming when the ozone concentration in the refrigerator exceeds a preset threshold value, and at night time, people have rest according to normal work and rest habits, and the use frequency of the refrigerator is greatly reduced, so that the opening and closing of the sterilizing device can be not automatically controlled at this time, only when the ozone concentration exceeds the preset threshold value and possibly hurts a human body, an alarm is sent out, if the refrigerator is used by a person in the period, a user can be reminded, the ozone concentration in the refrigerator is too high, and the sterilizing device can be manually closed by the user, wherein the alarm can be through displaying ozone concentration information and warning marks, and also through sound prompt and other modes.
By the sterilization control method of the embodiment, different control schemes are adopted for daytime and nighttime periods, and the opening and closing of the sterilization device is controlled according to the ozone concentration in the refrigerator in the daytime period; and at night, the alarm is given when the ozone concentration in the refrigerator exceeds the preset threshold value, so that the ozone concentration can be detected and controlled in real time, the situation that the user is damaged due to the fact that the ozone concentration in the refrigerator is too high when the user opens the refrigerator is avoided, and the safety is improved.
Example 2
In order to further realize the control of the opening and closing of the sterilization device according to the concentration of ozone in the refrigerator, the step S102 includes: determining a zone in which the ozone concentration is located, wherein different zones correspond to different control strategies; and controlling the opening and closing of the degerming device according to a control strategy corresponding to the section.
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 the refrigerator continues to rise, so that injury is caused to a user, and therefore the sterilization device needs to be triggered and controlled to be closed so as to stop ozone generation and further reduce the ozone concentration in the refrigerator; if the ozone concentration is smaller than the first threshold value and larger than the second threshold value, indicating that the ozone concentration in the refrigerator is in a safe range, triggering and controlling the sterilization device to keep a current on or off state, so that the oxygen concentration is kept in the safe range; if the ozone concentration is smaller than or equal to the second threshold value and the first preset time is continued, the fact that the ozone concentration in the refrigerator is very low at the moment is indicated, the human body cannot be injured even if the ozone concentration is continuously increased by a certain value, and in order to ensure the freshness of foods in the refrigerator, the sterilizing device needs to be triggered and controlled to be restarted.
In this embodiment, during the night time period, the alarm is given when the ozone concentration in the refrigerator exceeds the preset threshold, where the preset threshold may be equal to or unequal to the first threshold, and the invention is not limited specifically.
After triggering and controlling the sterilizing device to be restarted, ozone is generated, so that the concentration of the ozone in the refrigerator is increased, and after a second preset time passes, the sterilizing device is controlled to be opened and closed again according to the concentration of the ozone in the refrigerator in order to continuously ensure that the concentration of the ozone in the refrigerator does not exceed a safety range.
Since it is desirable to trigger a corresponding operation according to the concentration of ozone in the refrigerator, whether during daytime or nighttime, in some embodiments, monitoring the concentration of ozone in the refrigerator includes: the concentration of ozone in the refrigerator is detected by an ozone detector. In other embodiments, the ozone concentration may also be detected by a concentration detection unit inside the sterilization device.
In a specific implementation process, in order to realize the sterilization function, the sterilization device may be at least one of an ultraviolet sterilization device, a high-voltage electrostatic field device or an ABT sterilization device, and the invention is not limited in particular.
