Description

냉장고용 식품 관리 시스템{SYSTEM FOR MANAGING FOOD OF REFRIGERATOR}Food management system for refrigerators {SYSTEM FOR MANAGING FOOD OF REFRIGERATOR}

본 발명은 냉장고용 식품 관리 시스템에 관한 것으로, 보다 상세하게는 냉장고에 들어가는 식품의 정보를 인식하여 유통기한이나 보관 상태를 알려줌으로써 식품 관리를 용이하게 할 뿐만 아니라 음식물 쓰레기를 줄일 수 있는 냉장고용 식품 관리 시스템에 관한 것이다.The present invention relates to a food management system for a refrigerator, and more particularly, a food for a refrigerator that can reduce food waste as well as facilitating food management by recognizing information of a food entering the refrigerator and giving an expiration date or storage state. It relates to a management system.

일반적으로 냉장고는 냉기를 이용하여 냉동실 및 냉장실을 저온을 유지하여 식품 등을 저온 상태로 장기간 신선하게 저장하기 위한 장치로써, 산업사회가 발달되면서 엄청난 수요와 공급에 의해 지금은 집집마다 보급되어 있으며, 대부분의 사람들은 '냉장고의 음식은 상하지 않는다'는 인식이 있어 다량의 식품이나 음식 재료를 냉장고에 저장하고 있다.In general, the refrigerator is a device for storing food and the like freshly for a long time in a low temperature state by keeping the freezer and the refrigerating chamber at a low temperature by using cold air. Most people think that food in refrigerators don't hurt, so they store a lot of food or ingredients in the refrigerator.

일반적으로 냉장고에 저장되는 식품은 유통기한을 가지는데, 식품을 보다 효과적으로 관리하기 위해서는 각각의 식품의 유통기한이나 저장 상태를을 관리해야 한다.In general, the food stored in the refrigerator has an expiration date, in order to manage the food more effectively, it is necessary to manage the expiration date or storage state of each food.

그런데 이러한 냉장고는 크기가 점차 대형화되어 다양한 종류의 식품들이 냉장고 내부를 차지하게 되면서 냉장고 깊숙이 어떠한 식품이 보관되고 있는지 인지하지 못하고 방치하게 되는 경우가 빈번히 발생한다.However, as the refrigerator becomes larger in size and various types of food occupy the inside of the refrigerator, the refrigerator often does not recognize what food is stored deeply and is left unattended.

이러한 문제점을 인식하여 대한민국 공개특허 제10-2009-0105256호(음식물 관리시스템 및 이의 제어방법)에는 냉장고 내부에 구비되는 카메라를 통해 음식물에 구비된 바코드를 촬영하고, 휴대폰과 같은 모바일 장치의 키패드를 통하여 바코드에 음식물 정보를 저장한 후 이를 냉장고로 전송하여 표시하는 기술이 개시되어 있으며, 대한민국 등록특허 제10-1375906호(간편한 식품 관리를 위한 냉장고, 식품 관리 서버 및 식품 관리 방법)에는 바코드 리더 및 카메라를 내장하여 냉장고에 저장된 식품을 관리하는 기술이 개시되어 있다.Recognizing this problem, Korean Patent Laid-Open Publication No. 10-2009-0105256 (Food Management System and its control method) photographs a barcode provided in food through a camera provided inside a refrigerator, and uses a keypad of a mobile device such as a mobile phone. A technology for storing food information in a barcode and transmitting the same to a refrigerator is disclosed. Korean Patent No. 10-1375906 (Fridge, Food Management Server, and Food Management Method for Easy Food Management) includes a barcode reader and A technology for managing food stored in a refrigerator by embedding a camera is disclosed.

그러나, 상기와 같은 냉장고 식품을 관리하는 종래의 기술은 카메라나 이를 관리하는 제어 수단이 냉장고에 구비되어야 하므로 기존의 일반적인 냉장고에는 적용하기 어려운 단점이 있다.However, the conventional technology for managing the refrigerator food as described above has a disadvantage that it is difficult to apply to a conventional general refrigerator because a camera or a control means for managing the same should be provided in the refrigerator.
