Description

Refrigeration and freezing storage period reminder

The present invention relates to a refrigerating and freezing storage period notification device, and more specifically, the storage period of the contents with the list number is stored in the RAM connected to the microcomputer and the storage date and time entered by the user is built in the refrigerator The present invention relates to a refrigeration and freezing storage period notification device that can warn the user of storing in a refrigerator for a long time by outputting an alarm sound through a buzzer when the date and time of the clock circuit match.

In general, a refrigerator includes a compressor for compressing a refrigerant at a high temperature and high pressure, a condenser for condensing a high temperature and high pressure refrigerant compressed at a high temperature and high pressure in the compressor and converting the refrigerant into a high pressure liquid refrigerant, and condensing the liquid refrigerant with a high pressure in the condenser. It consists of an evaporator for evaporating the refrigerant to generate cold air, and a fan motor rotated to supply the cold air generated in the evaporator to the inside of the fresh food storage.

Such a conventional refrigerator, even if the user keeps the contents in the refrigerator and forgets to store the contents and is left for a long time, there is a problem that the refrigerator is left as it is until the user takes out the refrigerator.

In addition, by leaving the contents for a long time, the contents having a short shelf life have to be disposed beyond the shelf life and cause a bad smell of the refrigerator.

The long-term storage of unnecessary contents causes problems such as waste of power and deterioration of various parts of the refrigerator caused by overloading and refrigerating and freezing a large amount of contents of the refrigerator.

Accordingly, the present invention has been made to solve such a problem, the object of the present invention is that the user can not store all the contents of the refrigerator according to the size of the refrigerator, so that when the user stores the contents in the refrigerator by setting the storage period with the list number It is to provide a refrigeration and freezing storage period reminder that allows the user to recognize the storage period of the contents by displaying the list number on the LCD and outputting an alarm sound when the set date and time have elapsed. .

Still another object of the present invention is to prevent the user from forgetting the contents for a long time to prevent the disposal of the contents of short distribution period, such as milk, refrigeration and frozen storage period reminder to help intake food in a fresh state To provide.

The present invention stores the contents of the contents together with the list number stored in the RAM connected to the microcomputer and outputs an alarm sound through the buzzer when the date and time of the clock circuit built in the refrigerator matches the storage date and time entered by the user To work.

According to the present invention, by telling the storage period of the contents entered by the user through the buzzer, to prevent the contents stored by the user to be left in the refrigerator for a long time and to prevent the contents exceeding the valid period by mistake of the user by preventing food waste It has the effect of reducing diet and inducing proper eating.

In order to achieve the above object, the present invention includes a compressor, a condenser, an expansion valve, and an evaporator, and in a refrigerator absorbing heat from a low temperature object under the control of a microcomputer to refrigerate and freeze the contents, the date and time are counted. The clock circuit unit 10 and the time setting unit 20 for inputting the refrigeration and freezing storage period of the contents by the user's selection; and the data input to the time setting unit RAM (21) A time storage unit 30 for recording in the data memory 22 connected to the memory unit; and a comparison unit 40 for comparing the date and time of the clock circuit unit 10 and the time storage unit 20; and the clock. A display unit 50 for displaying the current date and time of the circuit unit 10 through the LCD 43 of the display driver circuit 42 connected to the display interface circuit 41; and by the output value of the comparison unit 40; Clock circuit unit 10 and time storage If the date and time of 30 matching alarm generating unit 60 to output a warning sound through a buzzer (51); characterized in that it comprises; microcomputer 70 which is programmed to whole constitute a control and.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The clock circuit unit 10 is connected to a clock signal output from the clock signal generation means connected to the clock signal generation means connected to the clock signal generation means, the power supply means for supplying power, the clock signal generation means for generating a clock signal, the storage means for storing date information, and the clock signal generation means. A time information generating means for generating time information in response, a counting means connected to said time information generating means, counting in response to time information output from said time information generating means, and outputting a count value, said counting means counting in said counting means And display means for displaying one count value on the LCD.

The time setting unit 20 is located in the front of the refrigerator, a setting key 11 for starting the setting of the reservation time, an addition key 12 for advancing the list number and the reservation time shown in the display means to the next, And a subtraction key 13 for returning the list number and the reservation time shown in the display means to the front, a completion key 14 for notifying the end of the time setting, and a numeric key 15 composed of Arabic numerals (0 to 9).

The time storage unit 30 is constituted by a storage circuit for recording the date and time reserved by the time setting unit 20 to the data memory 22 connected to the RAM 21.

Comparator 40 is composed of a comparison circuit for comparing the date and time of the clock circuit unit 10 and the time storage unit 20 to match.

The display unit 50 includes a display interface circuit 41 connected to the microcomputer 70, a display driver circuit 42 connected to the display interface circuit 41, and an LCD 43 connected to the display driver circuit 42. .

The alarm generating unit 60 includes a buzzer 51 for notifying the reservation time of the contents stored in the refrigerator when the date and time recorded in the time storage unit 30 arrive.

Hereinafter, the operation of the present invention having the above configuration will be described in detail with reference to FIG.

In the display unit 50 located at the front of the refrigerator, the current date and time are displayed on the LCD 43 by driving the clock circuit.

For example, suppose a user wants to keep pork until 7:30 pm on December 25, 97.

When the user selects the setting key 11 of the time setting unit 20, the text "list number" is displayed and the cursor blinks. When the user enters the list number using the numeric keys 15 and presses the completion key 14, the cursor blinks at the first number while the current date and time are displayed.

If 97 is entered using the addition key 12 and the subtraction key 13 and the completion key 14 is pressed, the cursor moves to the next space and instructs the month to be input. When the month is input using the addition key 12 and the subtraction key 13, the cursor moves to the next space and instructs to input the day.

By inputting the date and time and pressing the completion key 14 in this manner, the storage period desired by the user is input, and the input storage period is stored in the data memory 22 of the RAM 21.

The clock circuit unit 10 counts the time, and the comparison unit 40 compares the date and time of the clock circuit unit 10 with the date and time recorded in the time storage unit 30, that is, a storage period input by the user. , At 7:30 pm on December 25, 97, while the character “3: Pork” is displayed on the LCD 43, an alarm sound is output from the buzzer 51.

As described above, according to the refrigerating and freezing storage period notification device according to the present invention, by telling the storage period of the contents entered by the user through the buzzer, to prevent the contents stored by the user in the refrigerator for a long time and the user's mistake As it prevents the contents from exceeding the expiration date, it reduces the food waste and induces the correct diet.
