The dichroic LED 16 displays the position of the dichroic LED 16 on the same coordinates used to check the food. Try to find the dichroic LED closest to.

In addition, the microcomputer 20 stores a history input by the user using the input unit 23.

Referring to Figure 3 will be described a food display method of the refrigerator according to an embodiment of the present invention. When the user having the RFID tag 18 approaches the refrigerator, the RFID reader 21 receives the data transmitted from the RFID tag 18 and sends it to the microcomputer 20 (30). When the user's approach is detected, the microcomputer 20 allows the RFID reader 21 to receive data transmitted from the RFID tag 17 attached to the food inside the refrigerator compartment 11 and the freezer compartment 12. Check the location and type of food stored in the freezer compartment 12 (32). Then, by analyzing the data transmitted from the RFID tag 18 possessed by the user to check the history of the user approaching the refrigerator, and also check the food classification mode set by the user (34).

Then, using the data of the good food and the bad food for each disease or each food classification mode stored in the microcomputer 20, it is determined whether the food currently stored in the refrigerator compartment 11 and the freezing chamber 12 is good food or bad food (36). ). In this case, if the user has a disease and a food classification mode is set, food that is good for both the disease and food classification mode is classified as good food, and if any of the disease or food classification mode is bad food, it is classified as bad food.

When the stored food is classified, the microcomputer 20 determines whether the refrigerating compartment door 13 or the freezing compartment door 14 is opened by the input of the door switch 22 (38). If the refrigerating compartment door 13 or the freezing compartment door 14 are not all open, the display unit 25 displays whether the food stored as a letter is good food or bad food (42). However, when the refrigerator door 13 or the freezer door 14 is opened, the dichroic LEDs 16 installed on the shelves of the storage compartment where the door is opened differ depending on whether the stored food is good or bad food for the user's medical history or food separation mode. It emits light in color.

For example, if any food is a food that is good for the user's history or food classification mode, the dichroic LED 16 installed under the food is lit green, and if any food is food that is bad for the user's history or food classification mode. The dichroic LED 16 installed under the food is emitted in red (40). At this time, the microcomputer 20 checks the dichroic LED 16 located under each food by using the location data of the food identified in the previous step and the location data of the dichroic LED 16 previously stored in the microcomputer 20, The color of the dichroic LED 16 can be adjusted.

When only one of the plurality of storage compartment doors are opened from above, the storage compartment in which the door is opened indicates the good or bad of the food by the dichroic LED 16, and the good or bad of the food stored in the storage compartment in which the door is not opened is displayed on the display unit 25. Will be displayed.

As such, when the dichroic LED 16 under each food is emitted, the user can easily know whether the food is a good food or a bad food for his disease or a food classification mode set by the user.

In the present embodiment, when the user approaches the refrigerator but does not open the door, the display unit 25 displays whether the food stored in the refrigerating chamber 11 or the freezing chamber 12 is a good food or a bad food, but other means (eg For example, you can use voice output.

As described in detail above, the present invention displays the food and bad food in the user's medical history or a specific living mode, so that the user can more easily manage their diet.
