Description

Refrigerator with kimchi exclusive storage

More particularly, the present invention relates to a refrigerator having a kimchi storage bin, more specifically, to at least two separate kimchi storage baskets in a refrigerator of a general refrigerant cooling type, The present invention relates to a kimchi refrigerator having a kimchi storage bin for storing a kimchi taste for a long period of time by reducing the storage temperature flow width of the kimchi.

[0002] Refrigerators, which are widely used in general, have adopted cooling methods that generate cold air by using refrigerant.

Therefore, in order to preserve food in a refrigerated state in a refrigerator, it is necessary to inject cold air obtained by executing a normal refrigeration cycle with a refrigerant such as Freon gas into a refrigerated container at an appropriate time interval to maintain the storage temperature at an appropriate level.

However, in the current refrigerant cooling type refrigerator, the kimchi is refrigerated together with other refrigerated food. Therefore, if the refrigerator door is opened to take out the stored food, a food having a non-sealed or odorless odor, especially in kimchi And the smell spreading in the refrigerating chamber escaped from the outside, resulting in discomfort. In addition, when the refrigerated food or beverage is not completely sealed, there is a problem that the smell of kimchi in refrigerated foods and beverages is lost and the normal taste is lost.

Accordingly, there is a method of removing the smell of Kimchi by providing a deodorant or a deodorizing box in the refrigerator, but the deodorizing effect is not clear and the deodorant needs to be changed frequently.

In view of this, a refrigerator has been developed and used in which a separate kimchi storage room for separately storing kimchi is provided separately in the refrigerator compartment. In such a refrigerator, the disadvantages of the integrated refrigerator in which the kimchi are stored together are overcome, but the refrigerator uses the cool air generated by the refrigerant to keep the kimchi reservoir in a cooled state, resulting in the following disadvantages.

Generally, it is most preferable that the storage temperature of the kimchi is kept at 5 ° C. For example, according to the conventional kimchi fermentation method in which kimchi is placed in the ground with kimchi poison, the kimchi fermentation temperature is maintained at 5 ° C., It is known to be good.

However, as described above, in order to store the kimchi stored in the separate kimchi storage room by the cool air generated by the coolant cooling method, it is necessary to supply the cool air in units of 15 to 20 minutes. Therefore, The temperature inside the Kimchi reservoir will have a deviation of 4 ~ 12 ℃

As a result, there is a disadvantage that the taste of kimchi is easily changed because the storage temperature of kimchi can not be kept constant in the kimchi reservoir which uses cold air by refrigerant as in general refrigerator.

In order to compensate for these drawbacks, attempts have recently been made to reduce the temperature variation inside the refrigerating compartment by increasing the frequency of circulation of cold air by supplying cold air in 5 minutes increments. However, .

Accordingly, in order to overcome the disadvantages of the conventional refrigerator in which the kimchi reservoir separately provided in the refrigerator is cooled by the refrigerant cooling method, the refrigerator having the dedicated kimchi storage container using the thermoelectric device according to the present invention Respectively.

Accordingly, the present invention provides a refrigerator of a refrigerant cooling type having an outer case in the form of a rectangular box including a freezing compartment, a refrigerating compartment, and a kimchi compartment, comprising a kimchi reservoir inserted into the kimchi compartment and an outer case excluding the door side of the kimchi compartment A cooler passage formed between the reservoir and a kimchi reservoir which is attached to the inner wall surface of the rear wall of the reservoir and the inner wall of the rear wall of the case and which is exposed to the cool air flow passage and a thermistor sensor attached to the bottom surface of the reservoir I would like to provide a refrigerator.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a refrigerator having a kimchi storage bin according to the present invention will be described in detail with reference to the accompanying drawings.

1, the refrigerator 1 of the present invention is surrounded by an outer case 3 in the form of a rectangular box, and has a freezing compartment 5 and a refrigerating compartment 7 below the freezing compartment 5, have. In addition, a kimchi reservoir 9 for storing and storing only kimchi is provided at the lower end of the refrigerator 1, that is, below the refrigerating chamber 7.

As shown in FIG. 2, the kimchi reservoir 9 has a kimchi reservoir 11 inserted therein. The reservoir 11 is generally in the form of a box which is slightly smaller than the volume of the reservoir 9 and the door 13 of the kimchi reservoir 9 is opened to store the kimchi.

Therefore, since the reservoir 11 is placed on the seat portion 12 between the reservoir 11 and the outer case 3, not only the bottom surface of the reservoir 11 but also the opening 13 on the side of the door 13 of the reservoir 11 A cool air flow path 15 is formed so as to surround the entire outer peripheral surface of the reservoir 11 except for the part. The cool air for cooling the food inside the refrigerator compartment 7 is introduced into the reservoir 11 through the cool air inlet 31 which is opened at one side of the top surface of the kimchi compartment 9.

A cooling means 17 having a thermoelectric element for keeping the inside of the reservoir 11 in a refrigerated state is attached to a rear central portion of the rear wall of the reservoir 11, Is exposed to a portion of the cold air flow path (15) formed in the housing.

A mist sensor 19 is mounted on the bottom surface of the reservoir 11 to sense the temperature inside the reservoir 11 and detected by the control unit 33 built in the front of the door 13 of the kimchi storage 9 A thermistor sensor 19 adapted to send a temperature signal is mounted.

Here, the control unit 33 compares the delivered temperature signal with the set temperature, and controls the temperature of the reservoir 11 so that an appropriate current flows through the thermoelectric element 29 of the cooling means 17

4, the cooling means 17 includes a heat absorbing portion 25 of high thermal conductivity, which is also made of an aluminum material, which is in contact with the center of the rear surface of an aluminum-made reservoir 11 having high thermal conductivity, And a thermoelectric element 29 interposed between the heat absorbing portion 25 and the heat dissipating portion 27. The heat dissipating portion 27 and the heat dissipating portion 27 are connected to each other by bolts 35. [

Here, the heat absorbing portion 25 has a truncated conical shape in which the area of the heat absorbing portion 25 is gradually increased toward the reservoir 11 in order to speed up the cooling air delivery to the reservoir 11, Respectively.

In order to refrigerate the kimchi by the refrigerator 1 according to the present invention, the control unit 33 sets the desired kimchi storage temperature first. Thus, the inside temperature of the kimchi storage container 11 is controlled by the cooling means 17. At this time, the heat absorbing / heating effect occurring at the top and bottom of the thermoelectric element 29 of the cooling means 17 is utilized by the Peltier effect.

Here, the Peltier effect means that when current is supplied to two different N and P type semiconductor devices 39 connected in series by the copper plate 37 through the lead wire 41 as shown in FIG. 5, Refers to a phenomenon that heat is generated or absorbed from the upper and lower surfaces of the ceramic support plates 43, respectively.

Therefore, the heat absorbing portion 25 in contact with the upper surface of the thermoelectric element 29 supplied with current is cooled by the heat absorbing action of the thermoelectric element 29, 11 are also cooled simultaneously.

The cool air generated at this time spreads to the whole of the reservoir 11 by the heat conduction phenomenon, and the stored kimchi is refrigerated.

The heat generated from the lower surface of the thermoelectric element 29 due to the heat generated by the thermoelectric element 29 is dissipated through the heat dissipation unit 27. At this time, The heat generated from the lower surface must be removed more quickly.

Therefore, in the refrigerating chamber 7, the heat radiating portion 27 of the thermoelectric element 29 is cooled by the cooling air flowing into the kimchi reservoir 9 through the cooling air inlet 31, The heat dissipation unit 27 is exposed to the cool air passage 15 formed between the storage case 11 and the outer case 3 in the vicinity of the cool air inlet 31 so that the heat dissipation can be more effectively performed .

The magnetic field tube 11 is cooled not only by circulating the cold air introduced from the refrigerating chamber 7 through the cold air flow path 31 as a whole but also by the cooling means 17 to instantaneously control the refrigerating temperature in accordance with the set temperature have.

As shown in FIG. 6, the refrigerator 101 according to another embodiment of the present invention is substantially similar to the refrigerator 1 shown in FIG. 2, except that the funnel 11 has a plurality of heat insulating walls And the cooling means 117 of the same number as that of the storage chamber 123 is provided for each rear surface of each storage chamber 123 by the thermistor sensor 19 for each bottom surface, Is different from that of the first embodiment.

In this case, the stored kimchi may be stored in a control unit (not shown) so as to have an average degree of maturity of kimchi in one container, The refrigeration temperature can be set differently by each of the cooling means 117 mounted on the outer wall of the rear portion of each storage chamber 123 by the microcomputer built in the refrigerator.

Therefore, since the kimchi stored in each storage chamber 123 has different fermentation conditions according to the difference in the refrigeration temperature, the degree of fermentation varies according to the set storage temperature, so that the user can select and eat kimchi according to his / her taste.

According to the refrigerator of the present invention, since the kimchi can be stored separately by the storage compartment, the storage temperature of the kimchi can be kept constant regardless of the number of times of opening and closing of the refrigerator compartment door. Even if the refrigerator compartment door is opened to take out the refrigerated food other than kimchi, There is no discomfort due to the smell. Also, the disadvantage that the taste of the food is bad due to the odor of Kimchi is supplemented.

In addition, since the cool air generated by the coolant cooling system flowing through the cold air inlet 31 and the cool air generated by the cooling means with the thermoelectric element 29 can be stored at the same time, the kimchi refrigeration temperature can be maintained at the set temperature It can be kept constant within a range not largely deviated.

Therefore, a storage vessel is mounted in a separately provided kimchi reservoir, and a cooling means capable of adjusting the storage temperature according to the attribute of the preferred kimchi is installed in the reservoir to minimize the storage temperature deviation of the kimchi, Can be stored for a long time, the storage can be divided into at least two storage rooms to store the kimchi and according to the user's taste, the stored kimchi can be aged differently. .

Although the present invention has been shown and described with respect to specific embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the present invention as defined by the appended claims. Anyone with it will know easily.

It is an object of the present invention to provide a refrigerator having a separate storage for storing only kimchi in a refrigerator and a plurality of reservoirs for storing kimchi in accordance with the taste of the kimchi, A thermoelectric element is attached and the kimchi is stored and aged at a predetermined storage temperature to obtain a kimchi of a desired taste without inconvenience of use such as generation of malodor.
