Description of the Related Art Refrigerators for general household use, commercial use, laboratory use, etc. are widely used for storing and managing foods or articles requiring low temperature preservation. In such a refrigerator, an opening / closing door is generally provided on the front side, and by manually opening the door, the contents are put in and taken out and the internal state is checked.

には行うことができないのが現状である。[Problems to be Solved by the Invention] The ratio of stocking foods has increased more than before due to the recent tendency of working together as a couple. Along with this, it is desired that the refrigerator also be large-sized, and the variety of items stored in the refrigerator is increasing. This means that in general households, the rate of reliance on refrigerators for the preservation and management of food items is increasing, and along with this, the number of times food items are taken in and out and the number of times internal conditions are checked increase, Frequent opening and closing of doors is inevitable. Such opening / closing operation of the door is the largest factor that hinders the efficient cooling operation of the refrigerator. However, it is difficult for the user to memorize a large number of stored items, and it is the current situation that the user cannot select food or check the inside without opening the door.

いことではないこと等の事情から有効策ではない。A system has been developed in which an alarm sound or the like is emitted when the opening / closing door is opened for a certain period of time or longer. However, even if such an alarm sound is emitted, it is impossible to interrupt the food selection operation and the confirmation operation. Since it is not possible, it cannot be said that it is effective in solving the above situation. It is also conceivable that the opening / closing door is provided with a transparent portion to function as an internal peep window.
However, for the user, the heat insulating property deteriorates in that part, the storage space becomes small because the article cannot be stored inside the door that functions as a window, and the inside of the refrigerator is always visible from the outside. It is not an effective measure because it is not always desirable.

モリ２２に格納される。The CPU 28 also determines the shooting time and controls the shooting operation. For example, the angle sensor 3
Based on the signal from 0 and the time signal from the timer 34, it is determined that the opening / closing door 40 is operated in the opening direction. On the contrary, the decrease of the opening angle is reduced by the angle sensor 30.
Also, when judged based on the signal from the timer 34, a shutter operation signal is sent to the cameras 12 and 14 at a predetermined timing after the start of the closing operation. Based on this camera 1
2 and 14 respectively take pictures. At this time, the door 40
Although the angular position of is different every time, the range is limited to a certain distance range, so that a clear image can be taken without particularly focusing. However, each camera 12,
It is also possible to provide an automatic focusing device at 14 and perform delicate focus adjustment according to the distance. The image information thus captured is converted into a signal by the A / D converter and stored in the memory 22.

By performing the operation of 2, it is possible to request the image display of the inside condition of the refrigerator. That is, the internal situation image can be displayed without opening the opening / closing door 40. In the present embodiment, the operation unit 32 is provided with respective storage room keys 32a and door keys 32b for selecting the image display inside the storage room 42 or the image display inside the opening / closing door 40.
The user can request the image display on the desired side by pressing any key.

The operation signal is sent to the CPU 28, and the CPU reads the latest image signal captured by the storage room camera 12 from the signal stored in the memory 22, and the memory 22 reads the D / A converter 2 from the signal.
It is supplied to the display 26 via 4 and the image is displayed. Here, as the information read from the memory 22, only the information captured last is sufficient. Therefore, the memory 22
The image information can be stored only in the last captured image information. However, the present invention is not limited to this, and it is possible to store the image information of several images taken before that.
In that case, it is preferable to provide the operation unit 32 with an instruction key for displaying the image retrospectively.

In this embodiment, the displayed image is set to be displayed only for a certain period of time, for example, 30 seconds. The CPU 28 performs its control based on the signal from the timer 34. However, it is set so that the image can be erased before the elapse of 30 seconds by pressing the operation key 32a or 32b again. Further, in the present embodiment, the operation unit 32 is provided with a continuation key 32c, and when the continuation key 32c is pressed, the designated image display state is continued. This continuation state can be canceled by pressing the continuation key 32c again.

い。As described above, according to the above-described embodiment, it is possible to visually confirm the condition inside the refrigerator photographed by the camera without performing the opening operation of the opening / closing door 40. In the case of the storage state inside the opening / closing door, since there is no depth in the storage section, it is possible to almost completely know the current state of the beverage article or the like by displaying the image. Also, the image of the storage room side is also an image taken from the front side, but the frequently used ones are usually on the front side, and the food behind them is also to some extent. It can be confirmed, so there is no problem.

Shortening of the take-out work is also achieved. In addition, when thinking about what kind of stored food to use for cooking or making a shopping schedule, there is no escape of cold air by opening the opening / closing door 40, so that refrigerator cooling efficiency is also good. It is possible to contribute to energy saving.

For example, in the above-described embodiment, the time of photographing by the camera is set to a predetermined timing after the opening operation of the opening / closing door 40 is started. However, it is possible to simply use the angular position so that the shutter is released when the opening / closing door comes to a predetermined angular position. It is also possible to control. Further, in the above-described embodiment, the example in which the camera is provided only on the refrigerating room side is shown, but such a system can be applied to a freezer generally provided above the refrigerating room.

In other words, the entire operation from the opening operation of the door to the closing of the door including the operation of taking in / out the user's article is photographed,
It is also possible to display this as an image. In this case, a still image key may be provided on the operation unit 32, and the image may be stopped at a desired time point to display the same still image as in the case of capturing the still image.

As a result, it is possible to reduce the frequency of opening / closing operations of the refrigerator door, shorten the time required for moving foods and the like in and out, and greatly reduce the total time the refrigerator opening / closing doors are open. it can.
Therefore, efficiency of the cooling effect of the refrigerator and power saving are achieved.
