no. 1 Embodiment approach ）

[0046] Below, based on Figure 1 to Figure 20 The accompanying drawings illustrate the first embodiment of the present invention.

[0047] figure 1 It is a front view of refrigerator 100 of 1st Embodiment of this invention. figure 2 is a control block diagram of the refrigerator 100 . Figure 3A Is the refrigerator 100 figure 1 3A-3A sectional view. Figure 3B It is a front view when the refrigerator compartment door 12a of the refrigerator compartment 12 of the refrigerator 100 is opened.

[0048] Such as figure 1 , Figure 3A and Figure 3B As shown, refrigerator 100 includes refrigerator main body 11 . The refrigerator main body 11 is a heat-insulating box including an outer box mainly made of steel plates; an inner box formed of resin such as ABS; and a heat insulating material injected between the outer box and the inner box.

[0049] Such as figure 1 As shown, the refrigerator main body 11 is divided into a plurality of storage rooms by the heat insulation...

Abstract

A refrigerator equipped with: storage compartments which are partitioned by means of insulated walls and an insulated door, and in which storage objects are stored; a light source arranged within a storage compartment; an optical sensor (21) that detects illuminating light emitted from the light source; and a calculation control unit (1) that performs a calculation process on the basis of the detection result of the optical sensor (21). The calculation control unit (1) has: an attenuation rate calculation unit (81) which, on the basis of a standard storage compartment lighting intensity when there are no storage objects in the storage compartments and on the basis of the lighting intensity detected by the optical sensor (21), calculates an attenuation rate from a standard storage compartment lighting intensity when storage objects are stored; and a storage state estimation unit (82) which estimates the storage amount of the storage objects on the basis of the calculation result of the attenuation rate calculation unit (81).

Description

technical field [0001] The present invention relates to a refrigerator provided with means for detecting the storage state of storage items in a box. Background technique [0002] In recent household refrigerators, an indirect cooling method in which a fan is used to circulate cold air in the refrigerator is common. Conventional refrigerators maintain the temperature inside the box at an appropriate temperature by adjusting the control temperature based on the detection result of the temperature inside the box. [0003] For example, a refrigerator provided with a movable cold air discharge device is known as a refrigerator that maintains the temperature inside the cabinet uniformly (for example, refer to Patent Document 1). [0004] Figure 26 It is a front view showing the internal structure of refrigerator compartment 101 of conventional refrigerator 500 . [0005] Such as Figure 26 As shown, in the refrigerator 500, the movable cold air discharge device 102 provided in...
