The temperature of the freezing compartment 7, the first refrigerating compartment 8, and the second refrigerating compartment 9, which are divided separately, is measured to maintain a preset temperature, a maximum temperature, or a minimum temperature.

The operation of the refrigerator will be briefly described with reference to the above configuration.

Cold air formed through an evaporator (not shown) flows into the freezer compartment 7. The cold air flowing into the freezing compartment 7 flows into the first refrigerating compartment 8 through the first duct 12 by the first blowing fan 10, and likewise, by the second blowing fan 11. It flows into the 2nd refrigerating chamber 9 through the duct 13.

The cold air introduced into the first refrigerating chamber 8 and the second refrigerating chamber 9 flows back into the freezing chamber 7 through the first cold air discharging port 19 and the second cold air discharging port 20.

3 is a cross-sectional view taken along line II ′ of FIG. 2.

Referring to FIG. 3, the second refrigerating chamber 9 is formed with an upper wall 26 partitioned from the first refrigerating chamber 8, and an inside of the upper wall 26 includes a heat insulating material. 2 The wall which comprises both side surfaces and the lower side of the refrigerating chamber 9 also contains a heat insulating material.

In detail, a second duct 13 is formed between the freezing chamber 7 and the second refrigerating chamber 9 to introduce cold air from the freezing chamber 7, and the inside of the second duct 13 is formed. There is a damper (17) for controlling the inflow of cold air when the inflow of cold air from the freezing chamber (7), the lower portion of the second duct 13 so that the cold air of the second refrigerating chamber (9) to the freezing chamber (7) The second cold air discharge port 20 is formed.

On the other hand, although the damper is not formed in the second cold air discharge port 20, the damper may be formed similarly to the second duct 13.

The inside of the second refrigerating chamber (9) is provided with a basket (18) that can accommodate the kimchi storage container containing kimchi. The basket 18 is formed to move in a sliding manner, it is preferable that the basket 18 includes a heat insulating material so as to insulate itself. Since the basket 18 itself has a heat insulating function, it is possible to store kimchi that is required to be stored in a specific temperature range more efficiently.

In addition, a hole having the same shape as that of the second duct 13 is formed in one side surface of the basket 18 so that the cold air introduced through the second duct 13 may flow into the second refrigerating chamber 9. A hole having the same shape as that of the second cold air discharge port 20 is formed so that the cold air introduced into the basket 18 may be circulated inside the second refrigerating compartment 9 and discharged to the freezing compartment 7.

The operation of the configuration related to the second refrigerating compartment 9 will be briefly described with reference to the configuration described above.

When the temperature sensed by the third temperature sensor 25 to the inside of the second refrigerating chamber 9 is higher than a preset maximum temperature, the damper 17 is opened. When the damper 17 is opened, the cold air of the freezer compartment 7 flows into the second refrigerating compartment 9, and the introduced cold air lowers the temperature of the second refrigerating compartment 9. The introduced cold air is discharged back to the second cold air discharge port 20 while circulating the second refrigerating chamber 9.

When the temperature of the second refrigerating compartment 9 corresponds to a preset minimum temperature, the damper 17 that is open is closed to prevent the inflow of cold air from the freezing compartment 7, and no more cold air is introduced from the freezing compartment 7. By doing so, the temperature of the second refrigerating chamber 9 is not lower than the minimum temperature.

That is, the cold air of the freezer compartment 7 flows into or is blocked by the second freezer compartment 9 by the operation of the damper 17.

Hereinafter, the flow of cold air between the freezing chamber 7 and the second refrigerating chamber 9 will be described.

4 is a view showing the flow of cold air between the freezer compartment and the second refrigerating compartment according to the present invention.

Referring to Figure 4, the refrigerant flowing through the machine room passes through the evaporator and the cold air is formed while passing through the evaporator. The cold air generated through the evaporator is introduced into the freezing chamber 7 through the cold air discharge duct 26 to maintain the freezing chamber 7 in a low temperature environment.

The third temperature sensor 25 senses the temperature of the second refrigerating chamber 9 at a predetermined interval. When the temperature sensed by the third temperature sensor 25 is higher than the maximum temperature preset by the user, the damper 17 is opened. The cool air of the freezer compartment 7 is introduced into the second refrigerating compartment 9 by the opening of the damper 17.

The introduced cold air circulates through the second refrigerating chamber 9, and the circulating cold air is discharged into the freezing chamber 7 through the second cold air discharge port 20.

At this time, when the temperature of the second refrigerating compartment 9 by the third temperature sensor 25 corresponds to the preset minimum temperature, the damper 17 is closed and the cold air from the freezing compartment 7 to the second refrigerating compartment 9. Inflow is blocked.

By the flow of cold air as described above, the temperature of the second refrigerating chamber 9 can be controlled within a specific range, and thus, an appropriate environment for storing kimchi separately can be maintained.

The second refrigerating compartment 9 is formed on the lower side of the freezing compartment 7. According to this embodiment, the second refrigerating compartment 9 is located on the lower side of the freezing compartment 7. 2) less cold air flow into the second cold air discharge port 20, which helps to maintain a specific temperature desired by the user, and receives the cold air from the upper side of the second refrigerating chamber (9). ) Has the advantage of not having to form a cold air inlet hole in the basket (18).

Third embodiment

The third embodiment of the present invention is the same as that of the first embodiment in other parts, but differs only in the position of the second refrigerating chamber 9. Therefore, other configurations, reference numerals, and the like will only be described with reference to the first embodiment and the parts that are specifically changed.

6 is a cross-sectional view of a refrigerator according to a third embodiment of the present invention.

Referring to FIG. 6, the refrigerator includes a freezing compartment 7, a first refrigerating compartment 8, and a second refrigerating compartment 9. The refrigerator is located on a lower surface of the freezing compartment 7 to the second refrigerating compartment 9. It is formed between the second blowing fan 11, the freezing chamber 7 and the second refrigerating chamber 9 for sending, and serves as a flow path for the introduction of cold air into the second refrigerating chamber 9 by the second blowing fan 11. A second cold air discharge port 20 serving as a flow path for cooling air circulated in the second duct 13 and the second refrigerating compartment 9 toward the freezing compartment 7 is included.

On the other hand, since the basket 18 formed in the second refrigerating compartment 9 receives cold air from above, unlike the first embodiment, no hole for passing cold air is formed.

The second refrigerating compartment (9) is located in the lower portion of the freezer compartment (7) and the first refrigerating compartment (8), according to this embodiment, it is possible to store a larger amount of kimchi for those who normally consume a lot of kimchi There is an advantage.

Hereinafter, the temperature control by the temperature sensor of the refrigerator will be described.

7 is a block diagram showing a temperature control structure of a refrigerator according to the present invention.

Referring to FIG. 7, the maximum temperature and the minimum temperature of the second refrigerating chamber 9 are set in advance in the temperature control unit 6 located outside the freezer compartment door 2.

The temperature sensor 25 of the second refrigerating compartment 9 senses the temperature of the second refrigerating compartment 9 at predetermined intervals. When the temperature sensed by the third temperature sensor 25 is higher than the maximum temperature set in the temperature control unit 6, for example, 1 ° C., the damper 17 opens and the second blower fan 11 operates.

When the damper 17 is opened, the cold air of the freezing chamber 7 is introduced into the second refrigerating chamber 9 through the second duct 13 by the second blowing fan 11, and the introduced cold air is discharged from the second cold air discharge port ( 20) outflow. Even during the flow of cold air, the third temperature sensor 16 senses the temperature of the second refrigerating chamber 9 at a predetermined interval.

When the cold air of the freezing chamber 7 is introduced, when the temperature of the second refrigerating chamber 9 sensed by the third temperature sensor 25 becomes the minimum temperature, for example, 0 ° C., the damper of the second refrigerating chamber 9 ( 17) is closed.

When the damper 17 is closed, the inflow of cold air from the freezing chamber 7 is blocked. While repeating such an operation, the second refrigerating compartment 9 is controlled to maintain a desired temperature independently of the first refrigerating compartment 8.

On the other hand, although the damper is not formed in the second cold air outlet 20, the damper may be formed similarly to the structure of the second duct 11, and if the damper is formed, the operation of the damper is performed in the second duct 13 It can be set to be made simultaneously with opening and closing of the damper located in.

Since the temperatures of the freezer compartment and the first refrigerating compartment can be controlled by the same method as described above, the description thereof is weak.

In the case of a typical refrigerator, the temperature of the freezer compartment at the time of defrosting is maintained at a minimum of about -10 ℃, and has enough cooling power to refrigerate a small space, such as kimchi refrigerator compartment.

In addition, the second refrigerating chamber (9) can be used as a main purpose for storing kimchi, but can store foods that need to maintain a specific temperature for preservation, such as wine, beer.

According to the present invention there is an advantage that can be stored in a more accurate temperature range food that requires a specific temperature to be maintained for storage.

In particular, the amount of kimchi that is usually consumed in the kimchi refrigerator is not much, but it can give great satisfaction to those who are dissatisfied with the Kimchi storage ability of the existing refrigerator.

In addition, there is an advantage that can reduce the cost required to buy a separate kimchi refrigerator.
