Description
Technical Field
The invention relates to a screen display method for kitchen appliances.
Background
The existing kitchen appliance mostly comprises a display screen, the display state of the kitchen appliance is always high in brightness for the convenience of users, the power consumption of the kitchen appliance can be increased due to the fact that the display module is kept always bright, and the kitchen appliance does not accord with the green energy-saving concept. The prior art solves the problems by adjusting display backlight, and although the related industry also has a technology of adjusting screen brightness in a grading way, on one hand, the technology needs to acquire light intensity data in real time, which causes high power consumption, and on the other hand, when light intensity changes suddenly, the technology changes slowly and is easy to fluctuate. Meanwhile, the real low power consumption requirement is not met.
The screen display of the kitchen appliance is designed to meet the viewing setting of the user and is closely related to the distance between a human and a machine. A Chinese invention patent application with publication number CN106842971A (application number 201710135839.X) discloses a household appliance for controlling display state based on human beings and a control method thereof, wherein in the disclosed scheme, the household appliance is provided with a human-induced sensor, a human-computer interaction display screen and a main control system; when the human detection sensor detects that the user is in the household appliance operation area, a signal is output to the main control system, and the main control system activates the human-computer interaction display screen; when the human motion sensor does not detect that the user is in the household appliance operation area, a control signal is output to the main control system, and the main control system controls the human-computer interaction display screen to be in a standby state. The invention detects whether the user is in the area near the household appliance or not through the human perception sensor, and activates or controls the standby or the closing of the human-computer interaction display screen and the auxiliary function program thereof according to the operation condition of the user, has the characteristics of high flexibility and high automation degree, and can effectively save the energy consumption of the household appliance. However, in the area set by the home appliance, the activity frequency of the user is usually high, which may cause the continuous alternating state of the activated and closed display screens of the home appliance, and the real viewing requirement of the user cannot be judged, so that the effect of reducing the energy efficiency is limited, and the display screen is frequently activated and closed, which may easily cause the display screen to malfunction.
