Figure 21As shown, in use, the novel self-condensation glass door of the present application is first started to install the control unit in the box 23, the controller inside the box 233, the controller monitors the difference between the two groups of sensors of the humidity sensor and the temperature sensor inside the installation hole 2320 in the installation block 232 and the corner position of the double-layer glass 4 in real time, and monitors the distance between the transmitter and the receiver of the thickness detector, when the difference between the two temperature sensors and the humidity reaches the critical value of the glass condensation and the thickness detected by the thickness detector is larger, the controller starts the heater 21 and the air blower 22 to start;

[0078] Then the air blower 22 blows the heat generated by the heater 21 from the middle position inside the air supply box 20 to both sides, the airflow enters the connection frame 30 inside the air duct transport part 3 through the arc-shaped channel inside the box body shell 230, and the air supply beam 301 in the connection frame 30 sends the airflow into the inside of the special section plate 31 through the air supply socket 302;

[0079] Then the airflow forms a vortex in the mixing groove 314 inside the special section plate 31, and finally blows out from the slit air outlet groove 315, and the airflow blows out from the upper and lower through air supply grooves 101 opened in the front end of the inner side wall of the door body frame 10 near the bottom position and the several regularly distributed and inside and outside through air outlets 102 opened in the left and right ends of the inner side wall of the door body frame 10;

[0080] The blown air is adsorbed on the double-layer glass 4 and moves, and forms an air curtain on the double-layer glass to remove the condensation on the double-layer glass.
