working principle:

When the display cabinet of the present invention is used in summer, due to the high outdoor temperature, the display cabinet mainly provides a refrigeration function, especially for refrigerated sales of some bottled beverages, firstly, a temperature value is set for the temperature inside the cabinet, preferably 10°C, the temperature acquisition module collects the temperature value inside the cabinet at this time. If the temperature value inside the cabinet is less than 10°C, the temperature acquisition module feeds back the result to the PCB main control board. At this time, the PCB main control board Send a stop operation instruction to the refrigeration module system to make the compressor 5 stop. If the temperature inside the cabinet is greater than 10°C, the temperature acquisition module will feed back the result to the PCB main control board. At this time, the PCB main control The board sends an operation command to the refrigeration module system, so that the compressor 5 runs immediately until the internal temperature of the cabinet is ≤ 10 °C, the temperature at this moment is sensed by the temperature acquisition module, and fed back to the PCB main control board to stop the compressor 5. In operation, in particular, the temperature acquisition module can monitor the internal temperature of the cabinet in real time, so that the internal temperature of the cabinet is always in a state of ≤10°C, and the monitored temperature is fed back to the LED display 17 .

When the display cabinet of the present invention is used in winter, due to the low outdoor temperature, the display cabinet mainly provides a food heating function, especially for heating and heat preservation of some milk, soy milk and breakfast food for sale. The temperature is set to a heating and heat preservation temperature value, preferably 40°C. At this time, the temperature collection module collects the temperature value inside the cabinet. If the temperature value inside the cabinet is greater than 40°C, the temperature collection module feeds back the result to the cabinet. PCB main control board. At this time, the PCB main control board sends a stop operation instruction to the heating module system, so that the cross-flow fan 11 and the PTC heating module 12 are in a stop state. If the temperature inside the cabinet is less than 40°C at this time, the temperature The acquisition module feeds the result back to the PCB main control board. At this time, the PCB main control board sends an operation command to the heating module system, so that the cross-flow fan 11 and the PTC heating module 12 run immediately until the internal temperature of the cabinet is ≥40°C , the temperature at the moment is sensed by the temperature acquisition module, and fed back to the PCB main control board to stop the operation of the cross-flow fan 11 and the PTC heating module 12. In particular, the temperature acquisition module can monitor the internal temperature of the cabinet in real time, so that the inside of the cabinet can be The temperature is always in a state of ≥40°C, and the monitored temperature is fed back to the LED display 17 .

In particular, in order to better understand and realize the intelligent control function, the temperature sensing principle of the temperature acquisition module is briefly introduced. If the refrigerating function is operated in winter, the outdoor temperature will be much less than or equal to the temperature that needs to be set in the refrigerating room. At this time, the temperature acquisition module will compare the outdoor temperature and the set refrigerating temperature. If it senses that the outdoor temperature is far from the set value, it will feed back the result to the PCB main control board to enable the internal cooling module system and heating module. The system stops running to save power. If the heating and heat preservation function is performed in hot summer, when the room temperature exceeds 23 °C, the ambient temperature at this time is monitored by the temperature acquisition module, and the heating module system completely stops running, even if it is manually started, The heating module system will still not operate.
