Description

Technical Field

[0001] The utility model relates to the technical field of distance measuring sensor applications, in particular to a refrigerator using a TOF object detection distance measuring sensor. Background Art

[0002] As a highly integrated household appliance, the core function of the refrigerator is to maintain food and other items at low temperatures, effectively slowing spoilage and significantly extending their shelf life. With technological advancements, modern refrigerator designs have cleverly integrated cutting-edge technologies, particularly the innovative installation of various precision sensors on the refrigerator door. These sensors not only sensitively capture user gestures, enabling contactless intelligent interaction, but also significantly improve ease of use and efficiency.

[0003] The existing technology installs a TOF laser ranging function on the refrigerator door. The TOF ranging function is used to detect changes in the user's waving or foot waving movements. However, TOF laser is infrared light and the human eye cannot recognize the sensing range. Since the human eye cannot directly recognize the sensing range of TOF laser, users often find it difficult to accurately grasp the operating actions, resulting in the sensor being unable to be sensitively triggered, affecting the smoothness and accuracy of use. The TOF laser ranging device is usually installed on the refrigerator door in a fixed connection, which brings great inconvenience to subsequent inspection and maintenance work. Once the equipment fails or needs calibration, technicians often need to spend a lot of time and energy to disassemble and reinstall it, which not only increases maintenance costs, but may also cause unnecessary damage to the overall structure of the refrigerator.

[0037] The working principle of the present invention is as follows: the distance sensor assembly 3 is placed close to the door 2 of the refrigerator body 1, the male connector 5 is inserted into the female connector 4, and the power is turned on.

This innovation not only makes the sensing range clearly visible, but also can guide the user to accurately and quickly locate the sensing area, thereby greatly improving the user experience and accuracy of the distance measuring sensor. When the distance measuring sensor assembly 3 needs to be disassembled, it is also very simple and convenient, significantly reducing the time and energy required by technicians in repairing and maintaining the laser ranging device, avoiding frequent disassembly and reinstallation of the overall structure of the refrigerator, and thus reducing the risk of structural damage caused by improper operation or excessive disassembly.
