Title:
REFRIGERATOR
Document Type and Number:
Japanese Patent JP2013120048
Kind Code:
A
Abstract:

To solve a problem that since the weight of food is detected by providing a weight sensor on a shelf in a refrigerator and a set of four weight sensors are arranged for each of the shelves in the refrigerator to detect the weight of food, the cost is increased, and the control specification becomes complicated, and further, the correct weight detection becomes difficult due to entanglement of errors in the detection accuracy of each weight sensor.

A storage condition of food in a storage case 51 is determined by the weight detection by a strain gage sensor 53 arranged between the storage case 51 and a loading plate 52. Thereby, the number of necessary strain gage sensors 53 can be minimized to control cost increase, and duplication of errors of the plurality of strain gage sensors 53 can be avoided. Thus, the correct weight can be detected, and the food storage condition in the refrigerator can be grasped correctly.
