At this time, the main body 2 is formed in each storage space so that each storage container 6 can be inserted from the upper surface, the door 4 is the upper surface of each storage space to maintain the temperature of each storage space. At least one installation is preferred to prevent this.

Next, the storage container 6 is formed in a box shape that can accommodate kimchi, longevity, and the like, and is formed to have a lid so that it can be easily stored and sealed.

Of course, the storage container 6 may be configured in a variety of sizes, it is preferably formed in the same shape to be accommodated in the storage space.

Next, the RFID tag 12 is installed to be in contact with the storage space on one side of the storage container 6, the antenna unit (not shown) and the RFID integrated circuit (not shown) by the cover (not shown) Configured to be protected.

At this time, the antenna unit transmits a radio frequency including fermentation information, such as kimchi type, chapter type, fermentation period, and the like, the RFID integrated circuit using the energy of the radio frequency received from the antenna unit, the pre-stored fermentation food, fermentation Fermentation information, such as duration, is included in the radio frequency to be transmitted.

In addition, the cover part is divided into front and rear, the antenna unit and the RFID integrated circuit is built in, at least an attachment means (for example, an adhesive, etc.) is additionally formed on one surface thereof can be attached to the storage container (6). Make sure

Of course, the cover portion may further include an identification means for the user to visually check, it may be divided by color, number, etc. In this way, the identification means is associated with the fermentation information stored in the RFID integrated circuit, other RFID To be distinguished from the tag 12, different RFID tag 12 may be attached to each storage container (6) that stores different fermented food.

In addition, although the fermentation period may be input in advance for each fermented food, the RFID tag 12 may be input by separate input means 14 and RFID recording means 16 at the user's discretion.

At this time, the input means 14 is installed on the front of the main body 2 to receive the fermentation information from the user, while the RFID recording means 16 is the fermentation information input from the input means 14 The RFID tag 12 is installed to be embedded in one side of the storage space.

Of course, through the input means 14 and the RFID recording means 16, the user can input by adjusting the fermentation period for each fermented food, it is possible to input separately in different climates.

Next, the control means 20 is an RFID reading means 22 for obtaining fermentation information from the RFID tag 12, a one-hour number means 24 for calculating a date or time, and the RFID reading means 22. And a microcomputer 26 for determining the fermentation degree based on the signal transmitted from the one-time clock means 24 and displaying the same through the display means 30.

Specifically, the RFID reading means 22 also has a performance enough to read the RFID tag 12 when the RFID tag 12 approaches within a predetermined distance, but similarly to the RFID input means 14. The storage space is installed to be close to the RFID tag 12.

In this case, the RFID reading means 22 includes an antenna such as a predetermined frequency generating means, a transmitting means and a receiving means for recognizing the RFID tag 12, and at least such an antenna is installed at one side of each storage space in the store. And to receive the radio frequency from the RFID tag 12, it reads the fermentation information from the received radio frequency in this way to deliver to the microcomputer 26.

In addition, the one-hour clock means 24 calculates a date or time from a specific date, and the fermentation information is inputted from the input means 14 or from a specific record date for obtaining fermentation information from the RFID tag 12. This is done, and the calculation period is also passed to the macomb.

In this way, the microcomputer 26 receives the fermentation information from the RFID reading means 22 and at the same time receives and compares the calculation period from the one-hour clock means 24 to determine the degree of fermentation. When the included fermentation period is longer, the presentation degree is displayed through the display means 30.

Of course, the microcomputer 26 can determine and display the degree of fermentation as well as control the operation of the refrigeration cycle and the electric heater to control the degree of fermentation.

Next, the display means 30 may be composed of an LCD window mounted on the front of the main body 2, the display means 30 is connected to the microcomputer 26, the operation information, including the degree of fermentation To be displayed.

At this time, the display means 30 may add a function for notifying through an alarm or a light, when the calculation period is more than the set period than the fermentation period included in the fermentation information.

Figure 3 is a flow chart showing the operating state of the kimchi refrigerator using RFID according to the present invention.

In the first step, after storing the storage container 6 to which the RFID tag 12 is attached, and entering fermentation information, fermentation information is recorded on the RFID tag 12 (see S1, S2, and S3).

In this case, the RFID tag 12 may be previously recorded fermentation information including the fermentation period for each fermented food, but separately the user inputs fermentation information including the fermentation period for each fermented food arbitrarily through the input means (14) Then, it may be recorded by the RFID recording means 16.

More specifically, the RFID tag 12 may be recorded in a variety of fermentation information for each region in addition to kimchi type, chapter type, fermentation period, for example, cabbage kimchi can be set to have a fermentation period of 10 days to proceed. In addition, the fermentation period can be adjusted according to the user's preference.

Of course, the RFID tag 12 is attached to one side of the storage container 6 while the RFID recording means 16 is located in close proximity to the RFID tag 12 so as to record fermentation information. It is installed in the space.

In the second step, when the fermentation information is recorded in the RFID tag 12 in the first step, the date or time is calculated from the recording date, and the fermentation information is read from the RFID tag 12 (see S4 and S5).

In this case, when the RFID tag 12 approaches the set distance, the RFID reading means 22 generates a signal to the one clock number means 24 to calculate a date or time, and the RFID tag 12 The fermentation information including the fermentation period is read for each type of fermentation, and at the same time, each storage space to which the RFID tag 12 is attached is also read.

Of course, the fermentation information input through the input means 14 is recorded in the RFID tag 12 through the RFID recording means 16, the one clock means is the fermentation information through the input means 14 It may also be configured to calculate a date or time based on a signal transmitted simultaneously with the input.

In the third step, when the calculation period calculated in the second step has passed the fermentation period included in the fermentation information, the degree of fermentation according to the type of fermentation is displayed (see S6 and S7).

At this time, the microcomputer 26 obtains the fermentation information in advance through the RFID reading means 22, and then continuously receives the calculation period from the one-hour clock means 24, but the fermentation included in the calculation period and the fermentation information. Compare the time periods to determine the degree of fermentation.

Of course, the microcomputer 26 determines that the degree of ripening increases as the calculation period increases, and the fermentation period increases. Let the user know.

For example, if you read the fermentation information to make the fermentation of Chinese cabbage kimchi with a fermentation period of 10 days, tell the degree of ripening 1-2 days before the calculation period 10 days, or the day 10 days have passed It can inform the completion of fermentation, and furthermore, it can warn you through excessive alarming from 1 to 1 day after 10 days through an alarm, etc. Even if the user does not confirm it, fermentation stored in each storage container (6) easily The degree of ripening of food can be recognized.
