The invention relates to a control method of a variable-frequency refrigerator. The control method is particularly suitable for refrigerating plants like refrigerators which are relatively high in energy-saving requirement and easy to control. The refrigerator comprises a mechanical temperature controller, a variable-frequency control panel and a compressor, wherein the mechanical temperature controller is responsible for setting a refrigeration temperature in the refrigerator and outputting a corresponding switch signal according to an actual temperature in the refrigerator and the refrigeration temperature; the variable-frequency control panel is responsible for collecting the switch signal of the mechanical temperature controller, and analyzing and processing the switch signal to intelligently analyze the turn on / off time of the compressor, thereby controlling the running speed of the compressor. The control method of the variable-frequency refrigerator is simple in structure and convenient to operate, and particularly applicable to refrigeration control of the refrigerator. The variable-frequency control panel of the variable-frequency refrigerator can intelligently record the turn on / off ratio of the compressor, so that the running speed of the compressor is controlled and energy is saved.

The invention discloses an electric signal transmission device for preventing electrodes from falling off, which includes a casing, the interior of which includes an electric signal transmission body, and a plurality of first springs arranged on one side of the interior of the casing, and several first springs. The springs are all separated by partitions, and the upper and lower ends of the first spring are provided with clamping ports, and the contraction air bag can be inflated when the electrode plug is inserted into the connection hole of the electrode end through the provided contraction air bag, so that The anti-slip ring wraps the electrode plug to fix the electrode. When the electrode plug is loose, the anti-slip ring wrapped around the electrode plug is driven by the electrode plug to move outward so that one end of the limiting plate leaves the inside of the first spring, and the limiting plate leaves the first spring. The internal contact port of the spring is simultaneously displaced to contact with the second electrical terminal on one side of the partition to be energized, so that the first indicator light electrically connected to the contact port is energized and illuminated, thereby performing a light warning.
