Problems solved by technology

However, the function of the general display board is relatively simple, and its internal control unit is often relatively simple, often using a single-chip microcomputer, and the wireless communication module 10 generally uses a core controller, so that the wireless communication signal received by the wireless communication module 10 is transmitted through the display board 20 When sending to the main MCU, the signal channel becomes smaller, resulting in slower processing speed; and the signal generated by the control unit of the display panel will cause certain interference to the wireless communication signal, thereby affecting the stability of the wireless communication signal, and even data loss may occur

Abstract

The invention discloses a refrigerator. The refrigerator includes: a metal panel, on which a display window is opened; a circuit board, where the circuit board is located in the display window, and a ground plane and a feeding potential are arranged on the circuit board; at least two antenna pressing pieces, Wherein, one end of at least one antenna pressing piece is connected to the ground plane, and the other end is connected to the metal panel; one end of at least one antenna pressing piece is connected to the feeding potential, and the other end is connected to the metal panel. The embodiments of the present invention improve the stability of wireless communication signals.

Description

technical field [0001] The present disclosure relates to the technical field of refrigerators, in particular to a refrigerator. Background technique [0002] At present, smart refrigerators can be regulated by receiving wireless communication signals. Users can output wireless communication signals to regulate smart refrigerators through mobile terminals. Smart refrigerators perform function regulation according to the wireless communication signals, thereby facilitating users' use. [0003] related technologies, such as figure 1 As shown, the wireless communication module 10 is generally arranged on the top of the refrigerator and is separated from the display panel 20 of the refrigerator. The wireless communication module 10 is connected to the display panel 20 through a cable, and the communication connection with the main controller of the refrigerator is realized through the display panel 20, that is, The display board 20 is a connection transfer station between the ma...
