KR970022143A - Refrigerated food freshness display device and display method - Google Patents

Abstract

The present invention relates to a frozen food freshness display device and method of the refrigerator capable of displaying and checking the fresh state of the frozen food stored in the freezer compartment, and more specifically, the type of food stored in the freezer compartment in the freezer door. By installing the operation panel of food freshness display device that can set and display the storage period accordingly, it displays the temperature change of frozen food and the quality change of food according to the storage period to the user. A freshness display unit having a control switch, a selection switch, and a function button of a period display function, as well as an item switch for inputting or regulating a food name and a corresponding flow period of the food, and a freshness for displaying the food name according to the food item selection of the freshness display unit. A frozen food freshness display device comprising a display unit is configured, and the display is performed. When the frozen food name and the shelf life are input to the value, the first step of converting the input shelf life into days and the second step of comparing the freezer temperature detected by detecting the temperature of the freezer compartment with the lower limit temperature resulting in the quality change of the frozen food And, if the freezer compartment temperature is higher than the lower limit temperature, the third stage of comparing the freezer compartment temperature with the temperature set in multiple stages to shorten the distribution period according to the temperature change and compare the shortened distribution period and the set date for alarm of food quality change And, if the shorter shelf life is less than the set date characterized in that the frozen food freshness display method consisting of a fourth step that displays the food name and alerts the risk of food deterioration.

Description

Refrigerated food freshness display device and display method

As this is a public information case, the full text was not included.

1 is a schematic front view of a refrigerator equipped with a food freshness display device according to the present invention;

2 (a) (b) is an enlarged view of the operation panel showing the food nameplate attached to the front portion of the refrigerator freezer door of FIG. 1 and the freshness display attached to the food status indication attached to the trimmer plate, respectively;

3 is a control flow chart showing a frozen food freshness display method of the present invention.

Claims (3)

The operation panel of the food nameplate part 2 and the freshness display part 2 is installed in the freezer door 1 and the pre-plate 3, and the food nameplate part 2 selects the food items of the freshness display part 4. According to the name of the stored food is displayed, the item switch (4c) for selecting a button of the item, such as the period of distribution, food, removal, etc. on the freshness display unit 4, and is set to the corresponding item of the item switch (4c) A selection switch 4a for selecting and determining a data value, a period display tube 4d for displaying the distribution period of the food item corresponding to the item switch 4c, and a distribution period and a food name plate part of the period display plate 4d ( 2) The frozen food freshness display device of the refrigerator, characterized in that the functional means is provided, such as a control switch (4a) for selectively controlling the food. When the name of the frozen food stored in the freezer compartment and the shelf life of the frozen food freshness display device (2) and the freshness display unit and the corresponding shelf life are entered, the first stage (S1, S2) converting the input shelf life into days and the temperature of the freezer compartment Step 2 (S3, S4) of comparing the detected freezer temperature and the lower limit temperature resulting from the quality change of the frozen food, and if the freezer temperature is higher than the lower limit temperature, the freezer temperature is multi-stage compared with the temperature set in multiple stages. The third period (S5, S6, S7, S9-S14) comparing the shortened shelf life with the change of temperature and the set date for warning of food deterioration, and the shortened shelf life is less than the set date. Method for displaying the freshness of the frozen foods of the refrigerator, characterized in that consisting of the fourth step (S8) for displaying the food name and warning of the food deterioration. The method of claim 2, wherein in the third step, when the detected freezer temperature (F ° C.) is lower than the set first temperature (−l 2 ° C.), 0.5 days is subtracted from the remaining distribution period to convert the remaining distribution period of each food again. Step (S5, S6) and the detected freezer temperature (F ° C.) is higher than the first temperature (-12 ° C.) and lower than the second temperature (-9 ° C.), subtracting one day from the remaining shelf life. Reconstructing the remaining shelf life of the frozen food (S9, S10) and if the detected freezer temperature (F ℃) is higher than the second temperature (-9 ℃) and lower than the third temperature (-6 ℃) remaining Step 2 (S11, S12) to convert the remaining shelf life of each food by subtracting two days in the shelf life and the detected freezer temperature (F ° C) is higher than the third temperature (-6 ° C) and the fourth temperature ( If lower than -3 ℃) refrigeration characterized in that it consists of the step of converting the remaining shelf life of each food again by subtracting 4 days to the remaining shelf life (S13, S14) How freshness of frozen food. ※ Note: The disclosure is based on the initial application.
