Document Type and Number:
WIPO Patent Application WO/2021/212934
Kind Code:
A1
Abstract:
The present invention provides a color-changing door body, a refrigerator having same, and a control method for a color-changing door body. The door body comprises a main body, a light guide plate arranged at the front surface of the main body, a light-transmitting panel arranged at the front surface of the light guide plate, a color-changing light source arranged at the periphery of the light guide plate, a light-transmitting photosensitive pattern layer coated on the wall face of the light-transmitting panel close to the light guide plate, an illumination intensity sensor arranged on the door body, and a controller for controlling the color-changing light source and the photosensitive pattern layer, wherein the illumination intensity sensor is used for detecting the illumination intensity of the environment where the door body is located; and the controller is used for monitoring the resistance variation of the photosensitive pattern layer, and controlling whether to change the current on-off state of the color-changing light source and/or to change the magnitude of current of the color-changing light source according to the illumination intensity of the environment where the door body is located and the resistance variation state. By means of the present invention, the user experience is improved.
