Referring to
The switch 230 is coupled to the switch cover 200, and the switch cover 200 may be assembled into the cover hole 92 of the grille fan 90. The front surface of the switch 230 forms the same surface as the front surface of the switch cover 200 and may be exposed towards the refrigeration space 15.
The switch 230 includes a switch body 231 assembled in the switch cover 200. The switch body 231 is provided with a terminal 232. A pair of terminals 232 may be provided and may be connected to a lead wire W.
When the switch 230 generates an on signal, since the box body 102 is in a closed state by the box cover 105, the camera 120 may not capture an image.
When the switch 230 generates an off signal, since the upper portion of the box body 110 is in an open state, the camera 120 may capture (L) the image of the inside of the box body 102. The captured image is stored, and the stored image is output through the display of the refrigerator to help the user to recognize the objects stored in the box 100.
A method of operating the switch and the camera according to the present embodiment will be briefly described.
When the refrigerating space door 20 is opened, it is recognized that the refrigerating space door 20 is opened by a door switch (not shown), and the power of the camera 120 may be turned on.
As shown in
As an example, when detecting that the box 100 is withdrawn by a predetermined distance (e.g., in the range of 100 mm to 150 mm), or when a predetermined time (e.g., 1 to 2 seconds) elapses after the box 100 starts to be withdrawn, the camera 120 may capture an image.
The image obtained as a result of the capturing the image is stored in the refrigerator, and, when the refrigerating space door 20 is closed, the obtained image may be output through the display of the refrigerator. The user may perform food management by using the output image.
According to the present disclosure, by providing a switch on the rear wall of the storage space of the refrigerator to detect whether the vegetable box is withdrawn, it is possible to prevent interference between the switch and the cold air duct for the sidewall of the storage space. Therefore, industrial applicability is remarkable.
