Light sensing device, display control device and household appliance

Abstract

The embodiments of the invention provide a light sensing device, a display control device and a household appliance, which belong to the field of household appliances. The light sensing device includes a light sensor module and a first light blocking film. The light sensor module includes an emitting module and a receiving module. The receiving module is used for receiving light emitted by the emitting module and reflected, and generating an electrical signal according to the light received. The first light blocking film is disposed between the emitting module and the receiving module, and is used for preventing the diffused light of the emitting module from reaching the receiving module. The light sensing device is small in size, and thus the design space of the household appliance is greatly saved. The other objective of the invention is to provide a display control device and a household appliance. According to the display control device and the household appliance, a display module can be turned on in time when users need to watch the display module and can be turned off in time when users leave, and therefore, the electric energy consumed by the display module is significantly reduced.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a light sensing device, a display control device and a household appliance. Background technique [0002] Household appliances, such as dishwashers and refrigerators, are usually provided with display devices for displaying information such as the working status and various parameters of the household appliances. Among them, especially the dishwasher has developed into a must-have kitchen appliance abroad, and it has gradually become popular in every household in China. With the popularity of household appliances, the power consumption of household appliances is also increasing, so the concept of energy saving is increasingly put on the agenda. Reducing the power of core devices may affect the working effect, so the direction of saving power is locked to non-core modules, such as display modules. The TFT touch panel or the display button control panel of simple LED lights on...

Problems solved by technology

In this way, even when no one is watching the display, the display will still be in the display state, thus still causing unnecessary waste. The display module is a device used to remind the user of the working status of the household appliance. If the household appliance works for a long time but does not When people watch the display, and the display is always on, it will consume power in vain

[0003] In addition, the design space of the home appliance itself is limited, and when it is necessary to add additional functions to the home appliance, factors such as the appearance and volume of the home appliance must also be considered. Controls that take up little space
