Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refrigerator, and provides a method for storing food by inputting the type of food and the maximum number of days of storage into an input device, and then informing the user of the storage progress of the food as appropriate before the maximum number of storage days has elapsed. This system is designed to notify the user of the storage status of food, thereby preventing food from spoiling due to long-term storage beyond the storage limit and preventing food waste. .

Refrigerators are originally designed to store food for long periods of time, but depending on the type of food, there are limits to how long it can be stored, and if you forget how long the food has been stored and leave it as is,
Not only was food spoiled and wasted, but some people were unknowingly eating it and harming their health.

The present invention has been made in view of these points, and embodiments of the present invention shown in the drawings will be described in detail below.

FIG. 1 is a schematic block diagram showing an embodiment of the refrigerator of the present invention, FIG. 2 is an explanatory diagram showing a key switch constituting an input device, FIG. 3 is an explanatory diagram showing an example of a notification device, and FIG. 4 is an explanatory diagram showing an example of a notification device. FIG. 1 is a partial external perspective view of the refrigerator of the present invention. The input device 1 is for inputting the type of food and the storage limit number of days.
It consists of a key switch as shown in the figure.

This key switch has keys A to D, 1 to 0, day, reset, and check, and when each key is pressed, an output signal corresponding to the key is produced. The control section 2 is constituted by, for example, a microcomputer, and has an arithmetic and control unit 3, a storage device 4 constituted by a RAM, etc., and a counter 6 for counting days using the commercial frequency as a reference time.

The arithmetic control unit 3 inputs an output signal from the input device 1, that is, the key switch, and stores it in the storage device 4, and also controls the setting, reset, count-up, and countdown of the counter 5, and further inputs the stored contents of the storage device 4 and the counter. 5 and outputs the result as an output signal. The notification device 6 inputs the output signal from the arithmetic and control device 3 to notify the preservation progress of the food, and for example, as shown in FIG. Number display element 7
，? ...is established.

These numerical display elements 7, y... are sent from the arithmetic and control unit 3 which displays the result of subtraction between the contents of the storage device 4 indicating the storage limit number of days for the corresponding food and the contents of the counter 5 indicating the number of days elapsed from the start of storage. Depending on the output signal, the number of days remaining until the storage limit of the corresponding food is displayed. As shown in FIG. 4, the input device 1 and the notification device 6 are disposed at the front door of the refrigerator.

Next, “I will explain its operation.

For example, when storing beef, fish, ham, and poultry in the refrigerator, name them ``A'' for beef, ``B'' for fish, ``C'' for ham, and ○ for poultry. of,
A is the 5th, B is the 4th, and C is the 9th. If D is the 3rd, first press the keys on the key switch in the order of A, 5, and the day. Then, the arithmetic and control unit 3 writes the memory device 4's Counter 5 that stores 5 in and counts the number of days A is saved at the same time.
The counter 5G starts counting up from 0, while the notification device 66 outputs the is introduced to display the number on the number display element 5 corresponding to A, thereby informing the number of days remaining until the beef storage limit. In this way, if you press the key switch keys in the order of By 47 8 for fish, C 99 days for ham, and D 3 days for poultry, it will work in the same way as above. The number display elements 7, 7 corresponding to B, C, and D display the numbers 4, 9, and 3, respectively.

Therefore, the numbers displayed on each numerical display element 7, 7, etc. decrease sequentially as the number of days passes, allowing the user to see at a glance the storage limit for each food item. You can know the number of days left.

In addition, if you take out a stored food such as beef and store another food such as an egg, name the egg A and set its storage limit to 8 days.Reset the key switch, A, 8, Press in day order.

Then, the number of days remaining until the egg storage limit is displayed on the number display element 7 corresponding to A representing the egg, as described above. FIG. 5 is a schematic block diagram showing an example of a notification device, in which a voice synthesis device is used to notify the progress of preservation of food by voice.

FIGS. 6a and 6b are explanatory diagrams of the operation of the broadcast notification device, and N, ~
N9 indicates the initial address of each word segment, and I, 口...' indicate the petition pattern of each sentence. The address counter AC, also indicates the tone pattern of the ROM (read only memory) based on the output signal from the arithmetic and control unit 3.

This ROM Kamesama is used to store the order of word segments that make up a sentence as shown in Figure 6, and is used to sequentially input data to the address counter AC2 according to instructions from the address counter AC.
The address of ROM2 is specified based on the output signal from the ROM2.
This ROM2 is for storing audio digital quantization information, and stores the pieces of peas as shown in Figure 6M as audio pieces, and corresponds to the specified address according to the instruction from the address counter AC2. This outputs the word hollyhock as a digital code. Then, the output of this ROM2 is converted to an analog waveform suitable for audio output through a digital analog converter D/A and a low-pass filter LPF, and is output as audio from the speaker SP via the driver DR. An end code is included in the final step of each memorized word segment, and the end code of each word segment from N to N8 is different from the end code of the word segment of N9, such as EF and EF2. It is shown.

The end code detector JEF detects the end code EF of the word segment output from ROM2 and counts up the address counter AC, and the end code detector JEF2 detects the end code EF of the word segment output from ROM2. The code EF2 is detected and the address counter AC is cleared. In addition, when using such a notification device, when the check key of the key switch is pressed, the arithmetic and control device 3 first calculates the contents of the storage device 4 and the contents of the counter 5 for food A, and calculates the number of days remaining until the storage limit. If the number of days remaining corresponds to 0 or 1, a corresponding signal is output, and if the number of days remaining does not correspond, the process moves on to determining the number of days remaining for the next food B.

In addition, if the number of days left for food A corresponds to 0 or 1 day and a corresponding signal is output, "The determination of the number of days left for next food B starts by blocking the output signal from the end code detector JEF2. In this way, when the check key of the key switch is pressed, the arithmetic and control unit 3 sequentially determines the number of days remaining until the storage limit for each food product - Q.Next, the operation will be explained. Now, when the check key on the key switch is pressed, the arithmetic and control unit 3 first calculates the contents of the storage device mother and the contents of the counter 6 for food A to determine the number of days remaining until the storage limit.

As a result, when it is determined that the number of days left for food A is one day, the arithmetic and control unit 3 sends a signal to the address counter AC to instruct the signal pattern word order pattern I corresponding to the above-mentioned state of food A. input, address counter AC, mama ROM
Specify the first N5 of Den's word face pattern A. Then, first of all, the signal of N5 in the ROM is sent to the address counter AC.
2 and input RON by the address counter AC2.
Specify the address corresponding to N5 of 2. Therefore, R.O.
M2 outputs the word "shokuhin" as a digital code, and as a result, speaker SP outputs "
A voice saying "Shokuhin" is output. On the other hand, the end code detector JEF detects the end code EF of the word segment ``shokuhin'' and causes the address counter AC to count up by 11.
OM, inputs a signal corresponding to the next N, to the address counter AC2, and as a result, the ROM2 outputs a fragment of the word "Ei" as a digital code, and "A voice saying "Ei" comes from the speaker SP. is output.

After that, the same operation is repeated, and the speaker SP outputs sounds such as ``Shiyokuhin''rei'' and ``/1 ``atoichinichi'' and ``tersu'', but this also informs the user of the storage status of food A. It will make you recognize it. and"
When the end code EF2 of the last word segment "desu" is detected by the end code detector JEF2, this end code detector JEF2 is detected by the address counter AC2.
In addition, the arithmetic and control unit 3
Determines the number of days remaining until the storage limit for each food item.

In this way, the number of days remaining until food Q is determined sequentially.For example, if food C has reached its storage limit date, the speaker SP will say "Shokuhin", "Shi", "Ha".
It outputs a voice saying, "Death." FIG. 7 is a schematic block diagram showing an embodiment of the refrigerator according to the present invention. This is what I did.

That is, a switch 9 is provided to detect the opening and closing of the refrigerator door, and a check signal is input from the switch 9 to the arithmetic and control unit 3 when the door is opened. According to this system, each time the door is opened, the progress of preservation of the food is notified by voice, so the user can fully recognize the progress of preservation of the food, and can process the food reliably. According to the present invention, when storing food, by inputting the type of food and the storage limit number of days into the input device, the user can appropriately recognize the state of preservation of the food, and the number of days of preservation of the food There is no longer any need to forget about something and leave it as it is for a long period of time, allowing it to rot.
It is extremely useful.
