That is, the date / time display unit 135 displays time according to the output of the time counting circuit 120 and displays the date according to the output of the date counting circuit 130.

The refrigerator of the present invention includes a selection key unit 105 for inputting various types of information about the stored food, such as the kind, quantity, and storage period of the stored food stored in the refrigerator. The selection key unit 105, when inputting the information on the stored food, the location (holding room for storage of food, such as upper compartment, middle compartment, lower compartment, etc.) stored in the refrigerator compartment is input and stored together. Various information about the stored food input through the 105 is stored in the RAM 115 through the central processing unit 125 to be described later. Accordingly, the RAM 115 stores various kinds of information about the stored food after an address is designated in data storage as in the normal operation state.

The CPU 125 reads the stored food information stored in the RAM 115 and controls it to be displayed on various display units described below. That is, the stored food information stored in the RAM 115 is read based on the value output from the time counting circuit 120 at a predetermined cycle. Then, the stored food information read is controlled to be displayed on the stored food sequence display unit 145. That is, the central processing unit 125 changes the address of the stored food to be read from the RAM 115 based on the output of the time counting circuit 120, and in this way, reads the other stored food sequentially. .

In addition, the central processing unit 125 recognizes the preservation period information of the stored food stored in the RAM 115, the current time and date, and compares the two hours, the foods having passed the preservation period have passed. It is displayed on the display unit 140. The display of the expired food may be controlled by dividing the display state of the food displayed on the stored food sequential display unit 145 into negative / positive.

In addition, it is preferable that each of the display unit and the selection key described above is installed at the front of the refrigerator which the user can see well.

The following describes the storage food display control process of the refrigerator according to the present invention having the above configuration.

3 is an operation flowchart for controlling the display of the food stored in the refrigerator sequentially according to the present invention.

The oscillation output of the oscillation circuit 100 divides the oscillation output at a predetermined frequency, and then outputs the oscillation output to the time coefficient circuit 120. The time counting circuit 120 counts an input signal (step 200), and outputs a signal while clearing the counted value when the value counted in step 200 reaches a predetermined value (step 210). Step 220). The time on the date / time display unit 135 is changed and displayed based on the output of the time counting circuit 120.

In addition, the output of the time coefficient circuit 120 is input to the date coefficient circuit 120. The date counting circuit 120 counts an input time, changes a date when a predetermined time arrives, and outputs the date. The date displayed on the date / time display unit 135 is output based on the output of the date counting circuit 120. Is changed and displayed.

As described above, the signal counted by the predetermined time unit by the time counting circuit 120 is output to the central processing unit 125. When the signal is input from the time counting circuit 120, the CPU 125 reads the stored food stored at the current address +1 from the RAM 115 (step 230).

The stored food information read in step 230 is displayed on the stored food sequence display unit 145 (step 240).

However, while the time counting circuit 120 counts the time and the counted value reaches a predetermined time, the time counting circuit 120 is in a state where there is no output signal. As such, the CPU 125 continuously reads the stored food information corresponding to the current address from the RAM 115 until the next signal of the time counting circuit 120 is input to the CPU 125 (the Step 250), it is displayed on the stored food sequence display unit 145 (step 260).

If the stored food data stored in the RAM 115 is classified and stored according to a holding chamber (upper compartment, a lower compartment, a middle compartment, etc.) for storing the food in the refrigerator, the central processing unit 125 displays the time. Whenever a signal is input from the counting circuit 120, the signal is repeatedly read in order of upper column → middle column → lower column and displayed. Such a display state is shown in FIG.

The display state shown in FIG. 4 indicates that the output of the time counting circuit 120 is set to be output at a period of 5 seconds. That is, in the present state, if the stored food stored in the upper compartment of the refrigerator compartment is displayed on the stored food sequential display unit 145, after a predetermined time (5 seconds) elapses, it is stored at the current address +1 of the RAM 115. The stored food in the middle compartment is displayed on the stored food sequence display unit 145. In addition, when a certain time elapses, the food stored in the lower compartment of the refrigerating compartment is displayed, and when a certain time elapses, the food stored in the upper compartment of the refrigerating compartment is displayed. And during the predetermined time to maintain the state of continuously displaying the stored food currently read.

Next, during the control to sequentially rotate and display the food stored in the refrigerator at regular time intervals according to the above process, the central processing unit 125 recognizes information on the storage period of the stored food read from the RAM 115. . The current date is recognized from the outputs of the time counting circuit 120 and the date counting circuit 130. The storage date information thus recognized and the current date are compared and calculated, and the expired food is displayed through the expired food display unit 140.

That is, as shown in FIG. 4, when the onion preservation period has elapsed while the spinach and the onion of the middle can be displayed, the display of the onion is engraved so that the user is notified of the progress of the preservation period. To do that. It is also possible to display on a separate display unit. The word "expired food" is printed in advance on the front panel of the refrigerator, and the expired food is controlled to be displayed on the part of the "expired food".

As described above, after the food stored in the refrigerator is input and stored, the food name stored in each compartment of the refrigerator compartment is automatically displayed at regular intervals.

Therefore, the present invention controls the display unit provided on the front of the refrigerator to automatically display the name of the food stored in the store at regular intervals, and does not require a separate operation of the user to view the food in the store. Therefore, the present invention has the advantage that it is easy to check the food stored in the refrigerator within a predetermined time without the user's separate operation. In addition, the present invention has the advantage that can be informed of the storage state of the food to the user, while controlling the food to pass the storage period is displayed separately.
