That is, store the snack in the refrigerator compartment (6) of the refrigerator 1 (1), operate (for example, press) the recording switch a9 of the refrigerator compartment door a3, and write from the microphone to the storage means C241 that "the snack is in the refrigerator". ” (during this time, keep pressing the recording switch C19),
Even if you are away from home, if your child returns home afterward and operates the playback switch (for example, presses it momentarily), the storage method will be 0.
Since the message from the mother stored in 4) is output from the storage means (goods) and is emitted as voice from the speaker αη, the user can instantly recognize that there is a snack in the refrigerator compartment (6). Therefore, there is no need to write a message on paper and paste it on the refrigerator (1). Also, if you include the location of the snack in the message, the child will not have to search inside the refrigerator (6) afterward (and the leakage of cold air from the cold storage room (6) during that time can be reduced).

Also, store frozen food that is not to be eaten immediately in the freezer compartment (5), and store it as a memory means c! 41, you can check the food stored in the freezer compartment (5) K by operating the playback switch ■ any time thereafter.
Since there is no need to open and check the freezer compartment door α2, leakage of cold air from the freezer compartment (5) can also be reduced in this respect.

In addition, if you store food in the refrigerator (6) and store the storage limit "by what date should you eat it" in the storage device@, even if you forget the date and time when you stored the food, you can store it later. By operating the regeneration switch ■, the storage limit of the food concerned can be known, and the inconvenience of spoilage can be eliminated. That is, it can also be used as a warning means.

Next, when you remove the portable device hole and use it, for example, store the type and quantity of food you need to purchase from the microphone α, then insert the portable device hole into the holding part (to). Pull it out, take it with you, and go shopping. After that, if you operate the playback switch ■ at the store, storage means C24)
The stored information related to the food items that need to be purchased is played back on the speaker [η. This prevents you from forgetting to buy something, and also saves you the trouble of going out and writing it on paper.
The usability of the refrigerator is improved.

Also, because the battery was constantly being charged, the six outlets of the refrigerator (1) were accidentally unplugged after recording.
Even if a power outage occurs, the information in the storage means (goods) will not be erased and will be well retained.

Next, FIG. 7 shows another embodiment of the electric circuit of the portable device hole. In the figure, the same reference numerals as in FIG. 2 refer to the same parts. In this case, the recording/reproducing circuit (2) is a microphone α amplifier ■, A
/D converter and recording switch (part released from 19 (2)
a), a part (2b) consisting of a playback switch ■, a storage means (241, a D/A converter ■, an amplifier and a speaker wholesaler)
The part (2a) is installed in the handle I,
Insert only part (2b) and the battery into the portable device hole. In addition, a plug (35b) where the output of the recording switch (11) appears and a plug (35a) where the output of the D/A converter (c) appears on the bottom of the holding unit can, and a plug (35a) is added on the bottom of the portable device. (35b) corresponds to the recording switch (19).

) and a socket (31a) for inputting the D/A converter specific power into the storage means (to) are provided corresponding to the plug (35a). The other circuits of the refrigerator (1) are similar to those shown in FIG.

According to this embodiment, the circuit portion built into the portable device hole can be significantly reduced, so the size of the portable device hole can be reduced, making it easy to carry.

Incidentally, the information stored in the storage means (24) may be erased arbitrarily by providing an appropriate reset switch.
K may also be used so that it is erased at the same time as the playback ends. Further, in the embodiment, the storage means Q is constituted by a solid-state memory, but is not limited to this, and may be one for recording on a magnetic tape, for example.

(G) Effects of the Invention According to the present invention, arbitrary words can be stored in the storage means from the microphone while the portable device is housed in the holding part of the refrigerator, and thereafter can be played back at any time through the speaker installed in the cold AS. Therefore, it is possible to inform a person who has returned home while he/she is away that food is stored in the refrigerator, thereby improving usability. In addition, by storing information about the food stored in the refrigerator in the storage means, you can check the food inside the refrigerator without opening the door, thereby reducing the leakage of cold air from inside the refrigerator and improving cooling efficiency. In addition to this, it is also possible to issue a warning regarding the shelf life of stored foods. In particular, since a portable device equipped with at least a storage means and a reproducing function is removably installed in the refrigerator, it is possible to memorize the foods, etc. that need to be purchased, go shopping with the portable device, and reproduce them at the store. This eliminates the risk of forgetting to buy something, and also saves you the trouble of writing it down on paper, etc., which greatly improves the usability of the refrigerator.
