As shown in fig. 4, an embodiment of the present invention provides a method for controlling a deodorizer, which mainly includes the following steps:
s10, acquiring environmental parameters in the refrigerator around the deodorizer;
normally, the operating state of the deodorizer is determined by the operating state of the ozone generator 2, and when the ozone generator 2 generates ozone, the deodorizer is in the operating state; when the ozone generator 2 is stopped, the deodorizer is in a stopped state. And when detecting that the environmental parameters in the refrigerator change, determining the opening and closing state of the refrigerator door.
S20, judging the opening and closing state of the refrigerator door according to whether the environmental parameters around the deodorizer are mutated or not;
when the state of the refrigerator door is changed, environmental parameters such as ambient light, air pressure, air speed and temperature in the refrigerator are changed, and the opening and closing state of the refrigerator door is determined by detecting the change of the environmental parameters.
S30, when the door of the refrigerator is detected to be in the open state, the deodorizer is controlled to stop working; when the door of the refrigerator is detected to be switched from the door opening state to the door closing state, the deodorizer is controlled to be restarted.
Furthermore, in the step of judging the opening and closing state of the refrigerator door according to whether the environmental parameters around the deodorizer are mutated or not,
when the intensity of the obtained ambient light around the deodorizer is greater than or equal to the light intensity threshold, the refrigerator door is judged to be in a door opening state;
and when the obtained ambient light intensity around the deodorizer is smaller than the light intensity threshold value, judging that the refrigerator door is in a door closing state.
In the control method of the deodorizer of the embodiment, the opening and closing state of the refrigerator door is judged by detecting the ambient light intensity around the deodorizer, and when the refrigerator door is opened, the ambient light intensity exceeds a light intensity threshold value; when the refrigerator door is closed, the ambient light intensity is smaller than the light intensity threshold value, so that the opening and closing state of the refrigerator door is accurately determined, and the working state of the deodorizer is further controlled.
Further, the method further comprises an ozone concentration detection step, comprising:
acquiring a real-time ozone concentration value in the refrigerator;
when the detected real-time ozone concentration value is greater than or equal to the preset ozone concentration, controlling the ozone generator 2 and the fan 3 to stop working;
and when the detected real-time ozone concentration value is less than or equal to the preset minimum ozone concentration value, controlling the ozone generator 2 and the fan 3 to start working.
The control method of the deodorizer provided by the embodiment controls the working states of the ozone generator 2 and the fan 3 according to the implementation concentration value in the refrigerator, and stops the operation of the deodorizer when the ozone concentration in the refrigerator is too high, so that the highest ozone concentration in the refrigerator is maintained in a specified range, and meanwhile, the deodorizer can be matched with refrigerators with various capacities; when the concentration of ozone in the refrigerator is too low, the ozone generator 2 and the fan 3 are started in time.
Further, when detecting that the refrigerator door is switched from the door-opening state to the door-closing state, the deodorizer is controlled to restart, including:
when the controller 9 detects a restart instruction, the ozone generator 2 and the fan 3 are started in a delayed manner;
and when the working time of the ozone generator 2 is equal to the target working time, controlling the ozone generator 2 and the fan 3 to stop.

In the control method of the odor eliminator provided in this embodiment, when the refrigerator door is opened, the opening duration of the refrigerator door affects the ozone concentration value in the refrigerator, and when the opening duration of the refrigerator door is less than the preset opening duration threshold, the remaining operating duration of the ozone generator 2 is the difference between the target operating duration and the operating duration of the ozone generator 2, and if the preset opening duration threshold is set to 5s, the preset opening duration threshold can be determined according to the actual situation; when the opening time of the refrigerator door exceeds the preset opening time threshold, the opening time of the refrigerator door is in the process, the concentration of ozone in the refrigerator is rapidly reduced, the residual working time of the ozone generator 2 is the target working time, and the ozone generator 2 is restarted.
To facilitate an understanding of the invention, reference will be made to specific embodiments.

If the refrigerator door is not opened for a long time, if the refrigerator door is not opened for two hours, the deodorizer is opened again to prepare ozone, or when the real-time ozone concentration value detected by the ozone concentration sensor 6 is smaller than the preset minimum ozone concentration value, the deodorizer is opened again to prepare ozone.
When the operating mode of the deodorizer is in the traditional mode, as shown in fig. 6, the capacity of the refrigerator is selected on the display screen 7 to determine the target operating time of the deodorizer, the deodorizer is opened by pressing the key 8 for a long time, the ozone generator 2 and the fan 3 are started after the refrigerator door is closed for 2-5 min in a delayed manner to prepare ozone, whether the environmental parameters are mutated or not is monitored in real time in the process of preparing ozone, and if the environmental parameters are mutated, the refrigerator door is opened midway, and the deodorizer is controlled to pause; and if the environmental parameters are not mutated, controlling the deodorizer to stop working when the working time of the ozone generator 2 reaches the target working time.
In the operation process of the deodorizer, the refrigerator door is opened simultaneously, the opening time of the refrigerator door influences the ozone concentration value in the refrigerator, when the opening time of the refrigerator door is less than a preset opening time threshold, the residual working time of the ozone generator 2 is the difference value between the target working time and the working time of the ozone generator 2, if the preset opening time threshold is set to be 5s, the preset opening time threshold can be determined according to the actual condition; when the opening time of the refrigerator door exceeds the preset opening time threshold, the opening time of the refrigerator door is in the process, the concentration of ozone in the refrigerator is rapidly reduced, the residual working time of the ozone generator 2 is the target working time, and the ozone generator 2 is restarted.
