AI Technical Summary
The existing wireless communication unit layout of refrigerators lacks diversity, especially the configuration of the wireless communication unit and the shell is monotonous, which cannot effectively utilize the electromagnetic wave reflection characteristics of the metal shell, resulting in electromagnetic waves potentially canceling each other out and affecting communication reliability.
By setting an inclined surface on the metal casing of the refrigerator, the radio waves radiated from the antenna and reflected by the casing are directed in different directions, thereby avoiding radio wave cancellation, and a wireless module is set at the rear end of the casing to achieve diverse layouts.
It improves the reliability of wireless communication, suppresses the mutual cancellation of radio waves, enables stable communication of wireless modules, and allows for more layout options.
