Specifically, when the sliding door is opened and closed, the first electrode element and the second electrode element 322 contact each other through the first contact portion 3121 and the second contact portion 3222, so that the electric circuit is connected, and thus the electric heating diaphragm generates heat electrically to defog the glass door panel 221. When the sliding door is in an open state, the first contact portion 3121 is disconnected from the second contact portion 3222, that is, the circuit between the one electrode element and the second electrode element 322 is disconnected, and the electric heating diaphragm stops working, thereby reducing power consumption. Preferably, since the circuit is connected when the first electrode element and the second electrode element 322 are connected, in order to ensure that the sliding door can safely use the conductive element and avoid electric leakage, the first insulating seat 311 and the second insulating seat 321 are disposed outside the first electrode element 312 and the second electrode element 322, and simultaneously the connection between the first electrode element 312 and the sliding groove 12 and the connection between the second electrode element 322 and the door body structure 20 are isolated.

Further, the second contact portion 3222 is provided with a rolling sphere 3220, and the rolling sphere 3220 is configured to be slidably connected with the first contact portion 3121.

When the sliding door is closed, when the humidity sensor 24 monitors that the humidity on the glass door panel 221 is higher than%, the humidity sensor 24 transmits humidity data back to the PLC controller 23, the PLC controller 23 judges that the received data is larger than a set humidity range, and controls the circuit switch to enable the first conductive piece 31 to be communicated with the power supply, so that the electric heating diaphragm is electrified to generate heat, defogging work is started, and fog on the glass door panel 221 is clear. After the electric heating film is heated for demisting for a period of time, the humidity on the glass door panel 221 is reduced. When the humidity on the glass door panel 221 is lower than% the humidity sensor 24 transmits the humidity information back to the PLC controller 23, and the PLC controller 23 controls the circuit switch to be turned off, so that the first conductive member 31 is disconnected from the power supply, and the electric heating diaphragm is powered off, thereby stopping heating. The arrangement aims to reduce the energy consumption of the refrigerator, thereby achieving the purpose of energy conservation.

Furthermore, the control assembly is further provided with a temperature sensor 25, and the temperature sensor 25 is used for detecting the temperature of the electrothermal membrane; and the signal output end of the temperature sensor 25 is connected with the signal input end of the PLC 23. Further, a temperature range is further set on the PLC controller 23, and when the temperature sensor 25 monitors that the temperature of the electric heating diaphragm is too high, the PLC controller 23 controls the circuit switch to open the circuit, so that the first conductive member 31 is connected to the power supply. The arrangement can more accurately control the defogging work of the electrothermal film, and the use is safer.
