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 door body state detection method thereof. The refrigerator comprises a refrigerator body, a door body and a power supply hinge, wherein the power supply hinge comprises a first hinge part, a second hinge part, a first terminal and a second terminal; the first hinge part is mounted on one of the refrigerator body and the door body and is provided with a hinge hole; the second hinge part is mounted on the other one of the refrigerator body and the door body, and comprises a hinge shaft which is rotatably inserted into the hinge hole; the first terminal and the second terminal are respectively connected with an electric wire and are respectively arranged on the hole wall of the hinge hole and the peripheral surface of the hinge shaft; when the door body is closed, the second terminal and the first terminal are attached and electrified; and when the door body is opened in a rotating mode, the hinge shaft rotates relatively in the hinge hole, and the second terminal and the first terminal are staggered so that power failure can be achieved. According to the door body state detection method, whether the door body is in a closed state or an open state is judged by detecting whether the first terminal and the second terminal are in a switch-on conductive state or not. The door body power supply structure is novel, and the accuracy and reliability of the door body state detection method 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...
