Description

Control method of display device of refrigerator

The present invention relates to a control method of a display device of a refrigerator, and more particularly, to a control method of a display device of a refrigerator so that a user can easily know food in the refrigerator.

In general, a refrigerator is an electronic product used for keeping food fresh for a predetermined period of time. As shown in FIG. 1, the refrigerator is divided into a main body 10 and a freezer compartment for freezing and storing food in the main body 10. (11) and the refrigerating compartment 12 for refrigerating, the freezer compartment 13 installed at the front of the main body 10 to open and close the freezer compartment 11, and the refrigerating compartment door 14 for opening and closing the refrigerating compartment 12; It is largely composed of a freezing cycle for making cold air required for cooling the freezing chamber 11 and the refrigerating chamber 12, and cold air supply means for sending the cold air made in the freezing cycle to the freezing chamber 11 and the refrigerating chamber 12.

When the refrigeration cycle is supplied with refrigerated food in the freezer compartment 11 and the refrigerated chamber 12 is supplied with refrigerated food, the compressor (not shown) constituting the refrigeration cycle is driven by receiving a control signal from the controller. The low pressure gas refrigerant is compressed to a high temperature and high pressure gas refrigerant.

The compressed high-temperature, high-pressure gas refrigerant is guided through a connecting pipe (not shown) and condensed into a high-temperature, high-pressure liquid refrigerant while passing through a condenser (not shown). The condensed high-temperature, high-pressure liquid refrigerant is guided to the connecting pipe. The liquid is converted into a low-temperature, low-pressure liquid refrigerant which is rapidly dropped in temperature and pressure as it passes through a capillary tube (not shown), and is then guided through a connecting pipe to be converted into a low-temperature, low-pressure gas refrigerant while being passed through an evaporator. Cold air is generated because the surrounding air is heat-exchanged by the evaporation of the evaporator.

As such, the cold air generated in the evaporator (not shown) is partially supplied to the freezing chamber 11 by the cold air supply means to cool the freezing chamber 11, and thus the food stored in the freezing chamber 11 is frozen and a part of the cold chamber ( It is supplied to 12 to cool the refrigerating compartment 12, the food stored in the refrigerating compartment 12 is refrigerated.

The conventional refrigerator configured as described above has a problem in that warm air in the room is introduced into the freezing and refrigerating chamber of the refrigerator because the user frequently opens the freezing and refrigerating chamber door because the user does not accurately remember the food contained in the refrigerator.

Therefore, not only the freezing and refrigeration efficiency of the refrigerator is lowered, but also the freshness of the food is reduced due to the growth of microorganisms that cause food decay and deterioration.

In addition, unnecessary leakage of cold air occurs and power consumption increases, which causes energy waste.

The present invention has been made to solve the above-mentioned problems of the prior art, an object of the present invention is to provide a control method of the display device of the refrigerator that the user can easily check the food contained in the refrigerator.

The control method of the display apparatus of the refrigerator according to the present invention is characterized in that the user puts food in the refrigerator, and then inputs various data to the central control unit by operating Korean, English, numeric and special character keys, and the central control unit. And reading the data stored in the RAM according to the control signal, and displaying various data to the user in response to the control signal of the central controller.

Hereinafter, a preferred embodiment of a display device according to the present invention will be described with reference to the accompanying drawings.

FIG. 2 is a block diagram illustrating a display device according to the present invention, and FIG. 3 is a view illustrating a key operation panel and a display part of FIG. 2 installed at a predetermined position outside the refrigerator. A flow chart showing a control method.

Referring to Figure 2, the display device of the refrigerator according to the present invention, the user puts food in the refrigerator after the key (key) operation panel unit for operating the keys (Korean), English, numbers and special characters (key) And a central controller 21 for controlling the system according to the key operation of the key operation panel 20, a ROM 22 in which a program operates according to a control signal of the central controller 21, and a central controller. RAM 23 for storing the data selected in 21 and reading the stored data, and a display for notifying the user of various data (menu, date, time) in response to a control signal of the central controller 21. It consists of a part 24.

The key operating panel 20 and the display 24 are provided at predetermined positions outside the refrigerator as shown in FIG.

The operation of the display device according to the present invention configured as described above will be described with reference to FIG. 4.

First, the food to be put in the user's refrigerator is placed in the refrigerator, and then the Korean, English, numerals and special characters of the key operation panel 20 are operated to control the menu (kimchi, fish, beef) on the central control unit 21. ………) is input (S1).

Subsequently, the user inputs the date (1997, 8.15, ..., ...) and the time (18:30, ..., ...) to the central control unit 21 by manipulating the keys (S2) (S3).

At this time, the central control unit 21 temporarily stores various data in the RAM 23 according to a predetermined program stored in the ROM 22 according to the key operation of the key manipulation panel unit 20 (S4).

Various data stored in the RAM 23 is displayed on the display unit 24 by the control signal output from the central control unit 21 (kimchi, fish, beef ……), dates (1997, 8.15, ………) , Time (18:30, ..., ...), etc. are displayed (S5).

In the method of controlling the display device of the refrigerator according to the present invention, after the user puts food into the refrigerator, the user directly manipulates the key operation panel to control the display device even if the user does not open the freezer and refrigerator doors of the refrigerator after a long time. The displayed data allows the user to pinpoint the food in the refrigerator.

Therefore, it is possible to accurately grasp the food contained in the refrigerator without opening the freezing and refrigerating chamber door of the refrigerator, thereby increasing the freezing and refrigeration efficiency, and preventing the growth of microorganisms that cause food corruption and deterioration. Can be raised.

In addition, unnecessary leakage of cold air can be prevented, thereby reducing energy waste.
