Description

technical field

[0001] The invention relates to the field of food processing, in particular to a food processing machine. Background technique

[0002] At present, there are more and more types of food processors, such as broken wall cooking machines, soybean milk machines, etc., and more and more functions and forms, such as making soybean milk, fruit juice, ice cream / milkshake, crushed ice, rice paste, fine grinding and Minced meat, etc., and the motor is placed on the top, the motor is placed on the bottom, or the display operation is placed on the side, etc., resulting in multiple functions and functions. At this time, corresponding controls need to be set at different positions, and communication between different controls is required. In addition, food processors have a variety of working status signals that need to be collected by the acquisition unit, such as overflow prevention signals, water level signals, temperature signals, cup identification signals, lid openin...

Embodiment Construction

[0022] A food processor such as figure 1 As shown, it includes a main control circuit board and a slave control circuit board. The main control circuit board communicates with the slave control circuit board. The main control circuit board is provided with a power module. In this embodiment, the power module is A switching power supply, the switching power supply outputs a first DC power supply of voltage V1, the first DC power supply is electrically connected to the slave control circuit board through a power supply line, and the main control circuit board uses the first DC power supply The power supply is a baseband signal, and the main control communication signal is modulated into a carrier signal and transmitted to the slave control circuit board. The slave control circuit board is provided with an LDO voltage regulator, and the carrier signal is output after passing through the LDO voltage regulator. As for the slave control power supply, the slave control circuit board ...
