It should be understood that the specific embodiments described herein are only used to explain the embodiments of the present application and are not used to limit the embodiments of the present application.

[0042] The embodiment of the present application provides a WIFI module with enhanced communication capabilities. Figure 1 A schematic diagram of a WIFI module with enhanced communication capability provided in an embodiment of the present application Figure 1 , Figure 1 The module diagram of the WIFI module for enhancing communication capability is as follows: Figure 1 As shown, the WIFI module with enhanced communication capability includes a main control module 1, a switching module 2, a first antenna module 3 and a second antenna module 4.

The switching module 2 is electrically connected to the first antenna module 3 and the second antenna module 4, and is used to switch the first antenna module 3 or the second antenna module 4 based on the switching control signal. The first antenna module 3 and the second antenna module 4 have different setting directions, and the first antenna module 3 and the second antenna module 4 are connected to the metal shell of the kitchen appliance.

[0043] Through the above settings, by adding two antenna modules in different directions, the switching module 2 is used to switch the first antenna module 3 or the second antenna module 4 in different directions according to the current signal quality. The antenna modules in different directions are suitable for different usage scenarios. By switching the antenna module, the antenna setting method that best suits the current scenario is adapted, thereby enhancing the communication capability of the WIFI module of the kitchen appliance and improving the user experience. At the same time, most kitchen appliances use a metal shell (inner shell or outer shell), and the two antenna modules are connected to the metal shell to expand the communication signal reception range and avoid obstruction of the communication signal.

[0044] In a possible embodiment, the first antenna module 3 includes a first deflection antenna, and the second antenna module 4 includes a second deflection antenna.

When the current signal quality is poor, the main control module 1 can send a switching control signal to the switching module 2 to switch the antenna from the first deflection antenna to the second deflection antenna or from the second deflection antenna to the first deflection antenna. After a switching test, it can switch to the antenna setting method that best suits the current scenario, effectively enhancing the communication capability of the WIFI module of the kitchen appliance.

[0047] Through the above configuration, the two deflection antennas are connected to two mutually insulated metal shells to achieve multi-directional coverage of the antenna. Each metal shell can represent a different antenna direction, thereby achieving a wider WiFi signal coverage range. Furthermore, the isolation between the two mutually insulated metal shells can reduce interference between antennas, improve the performance stability of the overall system, and can also more flexibly adjust and optimize the layout and position of the antenna to meet the coverage requirements in different scenarios.

Figure 6 As shown, switching between the first deflection antenna and the second deflection antenna is achieved.

[0050] In an embodiment of the present application, the first antenna module 3 also includes a first impedance network, which is arranged between the first deflection antenna and the first output pin of the RF switch, and is used to match the impedance between the first deflection antenna and the RF switch to ensure maximum energy transmission and reduce signal reflection.

The WIFI module with enhanced communication capability is used to switch the first antenna module 3 or the second antenna module 4 based on the feedback signal.

[0058] In some optional embodiments, the current signal quality can be reflected in the form of a signal-to-noise ratio. The signal detection module 5 reads the signal-to-noise ratio in real time and sends it to the main control module 1. The main control module 1 switches the first antenna module 3 or the second antenna module 4 according to the signal-to-noise ratio value.
