As shown in fig. 5, the flow of the operation method of the packaged food vending machine 10 is as follows.
S100, when the environment temperature is detected to be higher than a first preset temperature, the refrigeration module operates to convey cold air to the storage cabinet.
After the packaged food is placed in the storage cabinet 100, the first preset temperature can be set to any one of 2 ℃ to 8 ℃ according to the type of the food in the packaged food. For example, if the first preset temperature is set to be 5 ℃, and if the ambient temperature is 5 ℃ higher than the set first preset temperature, the controller 400 automatically controls the refrigeration module 200 to start operating, and continuously supplies cold air to the packaged food storage area 111 in the cabinet 110, so that the temperature in the packaged food storage area 111 is kept below the first preset temperature of 5 ℃, thereby refrigerating the packaged food.
S200, when the refrigeration module runs to a first preset time point, the refrigeration module stops running, and the liquid storage tank heats the heat-conducting medium.
If the first predetermined time point is a time point before the meal time, for example, the first predetermined time point is set to 11 am, the controller 400 controls the refrigeration module 200 to stop operating when the refrigeration module 200 operates to the first predetermined time point of 11 am, and the refrigeration module 200 stops supplying cool air to the storage cabinet 100. Meanwhile, the controller 400 automatically controls the operation of the liquid storage tank 310, so that the heating body starts to heat the heat-conducting medium in the tank body.

The controller 400 controls the opening of the airflow exchanging window 700 to exchange airflow between the cabinet 110 and the external environment, so as to raise the temperature inside the cabinet 110 and start to warm the packaged food.
S400, when the temperature difference between the storage cabinet and the environment is detected to reach a preset range, or the liquid storage tank is heated to a second preset time point, closing the airflow exchange window.
After the cabinet 110 exchanges airflow with the outside for a period of time, the temperature in the cabinet 110 rises until the temperature difference with the ambient temperature reaches a preset range, and the controller 400 may control the airflow exchange window 700 to close. It should be noted that the predetermined range is 0 to 2 ℃. The second preset time point is a time point before the meal point, for example, if the second preset time point is set to 11:20, the controller 400 may control the airflow exchanging window 700 to be closed when the heating body heats the heat-conducting medium in the box body to the second preset time point 11: 20. Therefore, the controller 400 timely controls the airflow exchanging window 700 to close at any time of the time when the temperature difference between the storage cabinet 100 and the environment reaches the predetermined range and the second predetermined time.
