In addition, the position information of the washing machine in the place can be set in a manual setting mode, and specifically, when after-sales personnel send the washing machine to a user home, the position information of the room where the washing machine is located can be uploaded to a server to obtain the position information of the washing machine in the place.
Step S102: and matching the light environment type corresponding to the current position information of the washing equipment according to the corresponding relation between the preset light environment type and the position information.
In practical application, the corresponding relationship between the light environment type and the position information can be stored in the processing unit of the washing machine, so that after the position information of the washing machine is obtained, the light environment type corresponding to the current position information of the washing machine can be matched according to the corresponding relationship. The light environment type can be judged according to whether the variation of the environment light information in a certain time is larger than or equal to a preset variation threshold value.
Specifically, if the variation of the ambient light information within a certain time is greater than or equal to a preset variation threshold, the light environment with a large light variation may be determined, and if the variation of the ambient light information within a certain time is less than the preset variation threshold, the light environment with a small light variation may be determined. The light environment type of a kitchen or a toilet can be set in the processing unit of the washing machine as a light environment with small light change, and the light environment type of a balcony can be set as a light environment with large light change. After the current position information of the washing machine is obtained, the light environment type corresponding to the current position information of the washing machine can be matched according to the corresponding relation, taking the fact that the washing machine is located on a balcony as an example, the light environment type of the washing machine can be matched according to the corresponding relation, the light environment is large in light change, and therefore the brightness of the display device can be adjusted according to the light environment in the later period.

The corresponding relationship between a certain time period and the second brightness information may be stored in the processing unit of the washing machine, and specifically, a higher light value may be set for the middle time period of the day, and a lower light value may be set for the morning and evening without the sun, where the time period depends on the season and/or the illumination duration corresponding to the current time, and the illumination intensity at the same time may not be the same in different seasons, and the illumination intensity at the same time may not be the same in the same, different illumination durations, and the same illumination intensity at the same time. In practical applications, a timing device may be disposed in a chip of a processing unit of the washing machine, the timing device is used to obtain a current time, obtain second luminance information corresponding to the current time according to a corresponding relationship between a preset time period and the second luminance information, and adjust luminance of the display device according to the second luminance information, where the second luminance information may be a fixed luminance value that is the same as the first luminance information or a fixed luminance value that is different from the first luminance information.
In addition, the brightness of the display device can be adjusted according to weather conditions. Specifically, it may be determined whether the weather corresponding to the current time is a sunny day, and the second brightness information may be selectively adjusted according to the determination result.
If the weather corresponding to the current time is sunny, the second brightness information is not adjusted;
and if the weather corresponding to the current time is not sunny, adjusting the second brightness information to the first brightness information.
