Refrigerator light-sensing system capable of saving energy and reducing noise

Abstract

A refrigerator light-sensing system capable of saving energy and reducing noise comprising a refrigerator, a lower door hinge cover arranged at the lower end of the refrigerator, and a light-sensing device installed in the lower door hinge cover. The light-sensing device is electrically connected to the refrigerator through a wireless transmission or a wire connection mode. The light-sensing device is internally provided with a light-sensing element, a power supply module, a controller, a refrigerator refrigeration system and a light intensity storage module. The light-sensing element is configured to convert a detected light signal into an electrical signal and transmit the electrical signal to the controller. The controller may then determine a target temperature according to the intensity of the converted electrical signal. Through the refrigerator light-sensing system, the power consumption of the refrigerator can be reduced, and the noise can be reduced, providing a better user experience.

What is claimed is: 
     
         1 . A refrigerator light-sensing system capable of saving energy and reducing noise, comprising:
 a refrigerator,   a lower door hinge cover arranged at the lower end of the refrigerator, and   a light-sensing device installed in the lower door hinge cover, wherein the light-sensing device is electrically connected to the refrigerator through a wireless transmission or a wire connection mode.   
     
     
         2 . The refrigerator light-sensing system capable of saving energy and reducing noise of  claim 1 , wherein the light-sensing device is internally provided with a light-sensing element, a power supply module, a controller, a refrigerator refrigeration system and a light intensity storage module, wherein the light-sensing element is connected to the controller through a wireless transmission or a wire, and the light-sensing element is configured to convert a detected optical signal into an electrical signal, wherein the light intensity storage module in the light-sensing device is configured to store a light intensity value preset by a user. 
     
     
         3 . The refrigerator light-sensing system capable of saving energy and reducing noise of  claim 1 , wherein the controller in the light-sensing device is configured to determine a target temperature in the refrigerator according to the intensity of the light signal detected by the light-sensing element,
 wherein when the light intensity is lower than the preset value in the light intensity storage module, the controller adjusts the target temperature in the refrigerator from an original temperature to an updated temperature, wherein the updated temperature is higher than the original temperature,   wherein when the light-sensing device senses that the light intensity outside the refrigerator is restored to or greater than the preset value, the controller adjusts the target temperature in the refrigerator from the updated temperature back to the original temperature.   
     
     
         4 . The refrigerator light-sensing system capable of saving energy and reducing noise of  claim 3 , wherein the controller adjusts the target temperature in the refrigerator from an original temperature to an updated temperature comprises directly reducing the power of the refrigeration system to rise the target temperature from the original temperature to the updated temperature, wherein the controller adjusts the target temperature in the refrigerator from the updated temperature back to the original temperature comprises increasing the power of the refrigeration system to set the target temperature from the updated temperature back to the original temperature. 
     
     
         5 . The refrigerator light-sensing system capable of saving energy and reducing noise of  claim 3 , wherein the original temperature is set to 5° C., wherein the updated temperature is set to 5° C.
