[0038] Hereinafter, the refrigerator 80 of the first embodiment of the present invention will be described.

[0039] figure 1 It is a front view of refrigerator 80 in the first embodiment of the present invention, Figure 2A Is the cold storage 80 figure 1 The cross-sectional view of the 2A-2A line, Figure 2B This is a cross-sectional view when viewed from the front in a state where the refrigerator compartment door 12a of the refrigerator 80 is opened.

[0040] The refrigerator 80 has a heat-insulating box as the refrigerator main body 11. The refrigerator main body 11 mainly includes an outer box made of steel plate, an inner box made of resin such as ABS, and a heat insulating material injected between the outer box and the inner box.

[0041] The heat insulation box as the refrigerator main body 11 is divided into a plurality of storage compartments by heat insulation. Specifically, a refrigerating chamber 12 is provided at the uppermost part, and an ice making chamber 13 and...

Abstract

This refrigerator is provided with: a storage compartment having an opening at the front; a first light-emitting part (20a) disposed on the ceiling of the storage compartment; a first light detection part (21a) that detects light being emitted by the first light-emitting part (20a); and a recess (84) disposed on a side of the storage compartment. The first light detection part (21a) is disposed inside the recess. A refrigerator that is capable of estimating the storage state of items stored inside the refrigerator is thus provided. By performing control according to the storage state, the protection of freshness can be improved, and power consumption can be minimized by preventing excess refrigeration.

Description

Technical field [0001] The present invention relates to a refrigerator, and particularly relates to a refrigerator having a device for detecting the storage state in the refrigerator. Background technique [0002] In recent years, household refrigerators generally use an indirect cooling method that uses fans to circulate cold air in the refrigerator. In the existing refrigerator, temperature adjustment control is performed based on the detection result of the internal temperature, thereby maintaining the internal temperature at an appropriate temperature. [0003] For example, as a refrigerator that keeps the internal temperature uniform, there is a refrigerator provided with a movable cold air ejection device (for example, refer to Patent Document 1). [0004] Figure 21 It is a front view of the refrigerator compartment of a conventional refrigerator. [0005] Such as Figure 21 As shown, the movable cold air ejection device 102 installed in the refrigerating compartment 101 supplie...
