Problems solved by technology

However, after the refrigerator is used for a long time, the gap between the cabinet and the door will inevitably change, and sometimes it will exceed the effective sensing range of the magnetic switch and the columnar switch, making the sensing no longer accurate, resulting in wrong judgment of the door state

Abstract

The invention provides a refrigerator and a method for detecting the state of its door body. The refrigerator includes a box body, a door body, and a hinge assembly. The hinge assembly includes: a first hinge part installed on one of the box body and the door body; The hinge part is installed on the other of the box body and the door body, and is movably connected to the first hinge part; the first terminal and the second terminal are respectively connected to electric wires, and are respectively installed on the first hinge part and the second hinge part. Two hinge parts; when the door body is closed, the second terminal is attached to the first terminal to realize electrical conduction; when the door body is turned and opened, the relative position of the first hinge part and the second hinge part changes, prompting the second terminal out of contact with the first terminal for de-energizing. The door body state detection method judges whether the door body is in a closed state or an open state by detecting whether the first terminal and the second terminal are in a conductive state. In the present invention, the power supply structure of the door body is novel, and the accuracy and reliability of the method for detecting the state of the door body are higher.

Description

technical field [0001] The invention relates to a refrigerating and freezing device, in particular to a refrigerator and a method for detecting the state of a door body thereof. Background technique [0002] The main control board of the refrigerator is usually arranged in the box body, and some electrical components, such as a display screen, are also arranged on the door body. In order to supply power to the electrical parts of the door body, the hinge shaft is usually set as a hollow shaft, and the wires are passed through the through hole of the hinge shaft of the box body, then into the shaft sleeve of the door body, and finally connected to the electrical parts of the door body. This method is more complicated to operate in the production process, and the hollow structure of the hinge shaft also affects its strength. [0003] In addition, refrigerators often need to detect the state of the door body, that is, to confirm whether the door body is in a closed state or an...
