and step 110, acquiring light data of an external environment in real time through a photosensitive sensor outside the refrigerator, and sending the light data to the refrigerator controller.
A high-precision photosensitive sensor is arranged outside the refrigerator and used for collecting indoor light data so as to intelligently adjust the brightness of a refrigerating chamber illuminating lamp under the conditions of no light and bright light.
The photosensitive sensor is connected with the refrigerator controller, and after the photosensitive sensor collects light data, the light data can be sent to the refrigerator controller for data analysis.
Optionally, the refrigerator Controller may be a Central Processing Unit (CPU) installed inside the refrigerator, or may be a Programmable Logic Controller (PLC) installed inside the refrigerator.
And step 120, analyzing and processing the light data through the refrigerator controller according to a preset algorithm to determine an external light environment.
Wherein the predetermined algorithm includes at least one of filtering and mean value calculation.
The refrigerator controller may filter the collected light data to remove noise, and then calculate an average value of the filtered light data. In practical applications, the refrigerator controller may also use other algorithms to process the light ray data, which is not limited in this embodiment.
Optionally, referring to fig. 2 in combination, step 120 may include the following steps:
and step 121, calculating the illumination intensity of the current external environment according to a preset algorithm by the refrigerator controller.

Step 122, comparing the calculated illumination intensity with a predetermined threshold.
The predetermined threshold may be preset by a technician, and a value of the predetermined threshold may be determined by an experiment.
And step 123, when the illumination intensity is greater than or equal to the preset threshold value, determining that the external light environment is in the daytime.
If the illumination intensity is greater than the predetermined threshold value, it indicates that the current light environment is bright, and thus the external light environment is determined as the daytime.
And step 124, when the illumination intensity is less than the preset threshold value, determining that the external light environment is night.
If the illumination intensity is less than the predetermined threshold, it indicates that the current light environment is dark, and thus the external light environment is determined as night.
And step 130, determining the brightness of the refrigerating chamber lighting lamp according to the external light environment.
Optionally, referring to fig. 2 in combination, step 130 may include the following steps:
and step 131, when the external light environment is in the daytime, determining the brightness of the refrigerating chamber illuminating lamp as a first brightness.
In step 132, when the external light environment is at night, the brightness of the refrigerating chamber illumination lamp is determined as a second brightness.
Wherein the first brightness is greater than the second brightness.
Because illumination intensity is darker night, the luminance setting of the light under the night state is less than daytime, the problem that the light is too dazzling when the user opens the refrigerating chamber can be avoided, energy can be saved, and user experience can be improved.
And 140, setting the target brightness of the refrigerating chamber illuminating lamp according to the user type of the refrigerator and the determined brightness of the refrigerating chamber illuminating lamp.
It should be noted that, in actual use, if the user type of the refrigerator is not determined, the default is the normal user type, and the target brightness is directly set according to the determined brightness of the lighting lamp of the refrigerating chamber.
And 150, controlling the lighting lamp of the refrigerating chamber to work according to the target brightness through the refrigerator controller when the refrigerating chamber is in the door opening state.
Optionally, after the refrigerator is powered on, the usage habit of the user on the refrigerator within a period of time may be recorded by the refrigerator controller, and the user type of the refrigerator is determined according to the usage habit of the user. Referring collectively to FIG. 2, the determination of the user type may include the steps of:
and step 160, collecting the door opening times and the duration of each door opening through the refrigerator controller in a preset time period.
Alternatively, the predetermined period of time may be one week.
When the refrigerator is powered on for the first time, the refrigerator controller automatically collects the use data (the door opening times and the duration of each door opening) of the user within a preset time period.
Optionally, in practical applications, the refrigerator controller may re-execute step 160 and step 170 to re-determine the user type at predetermined time intervals, such as three months, so as to ensure that the user type of the refrigerator conforms to the usage habit of the user during the time interval.

And 172, when the door opening times exceed the first time threshold or the accumulated time length exceeds the first time threshold, determining that the user type of the refrigerator is the first type of user type.
The users with excessive door opening times or long accumulated time indicate the users who frequently use the refrigerator, and the first user type is a common user type.
Optionally, the first time threshold may be set to 100 and the first time threshold may be set to 25min for a one-week period.
And 173, when the door opening times exceed the second time threshold and the first time threshold and the accumulated time length does not exceed the first time threshold, or when the accumulated time length exceeds the second time threshold and the first time threshold and the door opening times do not exceed the first time threshold, determining that the user type of the refrigerator is the second type user type.
Optionally, for the one-week period, the second time threshold may be set to 50, and the second duration threshold may be set to 5 min.
Corresponding to the practical situation, the door opening times reach 50 times or the accumulated time reaches 5min, which indicates that the user is a common user, and the second type of user is a common user type.

And for the users with less door opening times and long accumulated time, the users are indicated to use the refrigerator infrequently, and the third type of user type is the user type which is not frequently used. For example, the user with the door opening times less than 50 and the accumulated time less than 5min is a less-frequently-used user.
The first time threshold is greater than the second time threshold, and the first duration threshold is greater than the second duration threshold.
The technician needs to set the first time threshold, the second time threshold, the first time threshold and the second time threshold to correspond to the predetermined time period.
Optionally, according to a specific user type, a specific adjustment manner of the target brightness may be shown in fig. 3, and the step 140 may include the following steps:
and step 141, when the user type of the refrigerator is the first type of user type, reducing the brightness of the refrigerating chamber illuminating lamp by a preset value, and setting the target brightness of the refrigerating chamber illuminating lamp according to the reduced brightness.
For the first type of user, after determining the brightness according to the external light environment, the determined brightness needs to be reduced to achieve the purpose of saving energy.

And 143, when the user type of the refrigerator is the third type, increasing the brightness of the refrigerating chamber illuminating lamp by a preset value, and setting the target brightness of the refrigerating chamber illuminating lamp according to the increased brightness.
The third type of user type is a less-frequently-used user type, and after the brightness is determined according to the external light environment, the determined brightness can be increased a little so as to provide a more efficient refrigerating chamber light environment for the user, and the user does not have a great influence on energy consumption because the user is not frequently used for a refrigerator.
Optionally, the predetermined value may be 2%, and on the basis of the determined brightness, if the user type is the third type of user type, the brightness of the lighting lamp of the refrigerating chamber needs to be increased by 2%.
