The present invention relates to a dedicated storage container for a refrigerator and a cooling structure according thereto, and more particularly, a dedicated storage container for a refrigerator capable of always maintaining an appropriate temperature by a dedicated container having a flow path portion through which cold air can be supplied between an inner wall and an outer wall. And a refrigerating chamber dedicated storage container cold air supply structure for supplying cold air supplied to the dedicated storage container.

In general, the refrigerator can maintain a low temperature state by the operation of the refrigeration cycle to store the items that need to be stored at a low temperature, usually in the freezer to store meat that requires refrigeration and various items that can be stored at a low temperature for a long time, In the general food and vegetables that require refrigeration will be stored.

An internal structure of the refrigeration and refrigerating chamber and a process of supplying cold air will be described with reference to the drawings. 1 is a cross-sectional view showing the internal structure of a conventional refrigerator, Figure 2 is a cross-sectional view taken along the line A-A of FIG.

As shown in the drawing, the low temperature cold air heat-exchanged in the evaporator 1a installed behind the freezing chamber 1 is partially supplied to the inside of the freezing chamber 1 through the shroud 1c by driving the blower fan 1b. The remaining cold air is supplied into the refrigerating chamber 4 through the refrigerating chamber duct 5 behind the refrigerating chamber 4 through the barrier 2. The supplied cold air is exchanged with food stored in the freezing and refrigerating chambers 1 and 4 so as to be changed to high temperature, and the evaporator through the return duct 3 connected to the lower side of the evaporator 1a through the inside of the barrier 2. After flowing to 1a), the process of heat-exchanging with the low-temperature refrigerant passing through the evaporator 1a again is repeated.

On the other hand, the recent interior storage has a variety of functions to maintain the optimal storage state by varying the amount of cold air supplied according to the food stored. For example, the structure of the crispy chamber 4a stored in the refrigerating chamber is included. In the refrigerator in which the crispy chamber 4a is provided in the refrigerating chamber, the amount of cold air supplied into the refrigerating chamber 4 is equal to each of the insides of the refrigerating chamber 4. It is adjusted differently depending on the position.

That is, as illustrated in FIG. 3, the cold air delivered to the cold air supply port 5a of the refrigerating chamber duct 5 through the lower portion of the evaporator 1a is formed on the left and right sides of the upper inlet of the refrigerating chamber duct 5, respectively. 6, 6 ') is supplied into the refrigerating chamber 4, and the cool air through the left cold air blocking membrane 6 in the drawing is transferred to the lower part of the refrigerating chamber 4 through the lower flow path 7 and discharges cold air ( Cool air is supplied to the lower end of the refrigerating chamber 4 through 7a). The cold air through the cold air blocking membrane 6 'on the right side is discharged through the crissing chamber flow path 8 through the crissing chamber discharge hole 8a to the crissing chamber 4a, and through the interruption flow path 9, the interrupted discharge air. Supply to refrigeration room interruption via (9a).

Each of the cold air blocking membranes 6 and 6 'is not opened and closed at the same time, but the opening and closing of the cold air blocking membranes 6 and 6' is controlled by the temperature sensed by the temperature sensing sensors a and a 'located inside the refrigerating chamber 4. That is, as shown in Figure 1 inside the refrigerating chamber (4) is a temperature sensor (a.a ') for detecting the temperature inside the refrigerating chamber (4) at the middle and the bottom, respectively, the temperature sensor (a The cold air blocking membrane 6 on the left side is adjusted according to the temperature sensed by) to supply cold air to the lower side of the refrigerating compartment 4, and the cold air blocking membrane on the right side according to the temperature detected by another temperature sensor a '. 6 'is opened and closed to stop the refrigerating compartment and to supply cold air to the crispy compartment 4a.

The cold air supplied by the left cold air blocking membrane 6 is configured to stop the supply of cold air when the temperature detected by the temperature sensor a is about 3 ° C. The cold air supplied by the right cold blocking film 6 'is configured to stop the supply of cold air when the temperature sensed by the temperature sensor a' reaches about 0 deg. The reason why the cold air is supplied differently according to each position in the refrigerating compartment 4 as described above is for optimal storage of food stored in each refrigerating compartment 4.

Among the foods stored in the refrigerator configured as described above, the most important food of Koreans is kimchi, which is stored in the refrigerating chamber. The kimchi is usually stored in the bottom of the refrigerating chamber (4) by putting it in a kimchi container. The lower part of the refrigerating chamber in which the kimchi is stored has a relatively higher temperature than the upper part of the refrigerating chamber, and thus the kimchi in the kimchi container stored in the lower part of the refrigerating chamber is easily fermented, which makes it difficult to store for a long time.

In order to solve the above problems, it is possible to maintain the low temperature by increasing the amount of cold air supplied to the lower part of the refrigerating chamber, but in this case, the problem that proper refrigeration cannot be made due to the temperature decrease of other foods stored in the lower part of the refrigerating chamber. do.

The present invention is to solve the above problems, it is an object to provide a kimchi-only container equipped with a cold air passage through which cold air passes so that the kimchi can be stored unchanged for a long time.

Still another object of the present invention is to provide a dedicated flow path for supplying low temperature cold air suitable for a kimchi container so that the kimchi stored in the kimchi container is maintained in an optimal state.

4 is a cross-sectional view showing the structure of the cold air flow path of the refrigerating compartment according to the present invention, Figure 5 is a partial cross-sectional view of the refrigerating compartment showing the supply of cold air into the refrigerating chamber dedicated storage container according to the present invention.

Usually, the cold air heat exchanged in the evaporator 1a flows into the cold air supply port 10 connected to the barrier 2 through the bottom of the evaporator 1a, as shown in FIG. Inlet). In addition, the inlet of the refrigerating chamber duct 30 is provided with cold air blocking membranes 20 and 20 'opened by a cold air conditioner (not shown), and the cold air blocking membranes 20 and 20' are provided in the refrigerating chamber 4. The opening and closing is adjusted according to the temperature sensed by the temperature sensor (a, a ').

Meanwhile, as illustrated in FIG. 4, two cold air blocking membranes 20 and 20 ′ are formed at left and right sides, respectively, and the cold air blocking membrane 20 on the left side is opened and closed according to the temperature at the lower end of the refrigerating chamber, and the cold air blocking membrane on the right side. 20 'is opened and closed depending on the temperature of the refrigerator compartment stop.

In addition, the refrigerator compartment lower passage 40 is connected to the left cold barrier membrane 20 so that the cold air through the cold air barrier membrane 20 on the left side may be supplied to the cold compartment lower end, and the lower passage 40 at the end of the cold compartment lower passage 40. Cold air discharge holes 42 for discharging cold air through the 40 are formed.

The cold air through the right cold blocking film 20 'is supplied to the crissing chamber 4a formed at the upper side of the refrigerating chamber, the refrigerating chamber stop, and the refrigerating chamber dedicated storage container 100 described later. That is, the crissing chamber flow path 50 for supplying cold air to the crissing chamber 4a above the refrigerating chamber, the refrigerating chamber interruption flow path 60 for supplying cold air to the refrigerating chamber stop, and the dedicated storage container 100 for supplying cold air. A dedicated storage container flow path 70 is connected to the right cold blocking film 20 ', and the cool air through the cold air blocking film 20' is supplied along each of the cold air flow paths 50, 60, and 70 and the crissing chamber 4a and Refrigeration chamber is stopped and supplied to the dedicated storage container (100). In addition, the right side air barrier membrane 20 'is opened and closed by a temperature detected by a temperature sensor a' installed at the refrigerating chamber stop, and the temperature is maintained at about 0 ° C-1 ° C.

Cold air discharge holes 52 and 62 for discharging cold air through the respective flow paths 50 and 60 are formed at ends of the crissing chamber flow path 50 and the refrigerating chamber interruption flow path 60. In addition, the dedicated storage container flow path 70 is provided with a plurality of flow path outlets 72, so that the dedicated storage container 100 stored in the refrigerating compartment can supply cold air at any position inside the refrigerating compartment 4. For sake.

That is, even if the dedicated storage container 100 is placed at any position of the lower end, the middle and the upper end of the refrigerating chamber 4, it is possible to receive cold air through the flow path outlet 72 placed at each shelf position. For example, if the dedicated storage container 100 is placed at the bottom of the refrigerating chamber, the cold air is supplied into the dedicated storage container through the flow path 72 located at the bottom.

In addition, unlike each of the crissing chamber flow path 50 and the refrigerating chamber interruption flow path 60, each of the flow path outlets 72 formed on the dedicated storage container flow path 70 is provided with a cold air discharge film 74. The cold air discharge membrane 74 is supported by the elastically actuated spring (74a) to control the opening and closing. That is, when the dedicated storage container 100 is not coupled, the cold air discharge membrane 74 is supported by the spring (74a) to block the flow path outlet 72, thereby passing through the cold air blocking membrane 20 ' The cold air introduced into the storage vessel flow path 70 is prevented from leaking outside by the cold air discharge membrane 74.

However, as shown in FIG. 5, when the dedicated storage container 100 is coupled to the flow path outlet 72, the cold air suction opening 132 formed at one side of the upper end of the dedicated storage container 100 through the flow path outlet 72. As it is inserted into the dedicated storage container flow path 70, the cold air discharge membrane 74 is pushed back, thereby opening the cold air discharge membrane 74.

Next, the refrigerator compartment storage container 100 according to the present invention through Figure 5 will be described. As shown, the main body 12 of the storage container 100 is made of a double of the inner wall 122 and the outer wall 124, the body through which cold air passes through the space between the inner wall 122 and the outer wall 124. The flow path 130 is formed. On both sides of the upper end of the main body 120, an inlet 132 and a main body passage outlet 134 of the main body passage 130 formed of the inner wall 122 and the outer wall 124 are formed, respectively, and are introduced into the inlet 132. The cold air exits through the cold air outlet 134 through the main body channel 130. And a cover 110 for opening and closing the main body 120 is formed on the upper portion of the main body 120.

The use state of the refrigerating chamber cold air flow path and the refrigerating chamber dedicated storage container having the above structure will be described.

First, for example, after putting kimchi in the dedicated storage container 100, the cold air suction port 132 of the dedicated storage container 100 is inserted into the interior through the flow path outlet 72 of the dedicated storage container flow path (70). . As the cold air suction port 132 of the dedicated storage container 100 is inserted, the cold air discharging membrane 74 is pushed backward to maintain the flow path outlet 72 open, and the cold air through the flow path outlet 72 is cold air. Through the inlet 132 may be introduced into the main body flow path 130 formed in the main body 120 of the dedicated storage container 100.

In the above state, the left and right cold air blocking membranes 20 and 20 'are opened according to the temperature sensed by the temperature sensing sensors a and a' inside the refrigerating chamber 4, and the inlet to the inlet of the refrigerating chamber duct 30 is opened. The cold air is passed through the cold air barrier membrane 20 on the left side to the cold compartment lower end through the cold compartment lower passage 40, and passes through the cold air barrier membrane 20 ′ on the right side to the crissing chamber euro 50 and the cold compartment interruption passage 60. As a result, cold air is supplied into the refrigerating chamber stop and the crissing chamber 4a.

Meanwhile, a part of the cold air passing through the right cold blocking membrane 20 'is introduced along the dedicated storage container flow path 70. At this time, the channel outlet 72 to which the dedicated storage container 100 is not coupled is the cold air discharge film 74. ) Is closed by being blocked by its own elastic force of the spring (74a), so that no cold air flows out, and the cold air discharge membrane (74) on the side of the channel outlet (72) to which the dedicated storage container (100) is coupled remains open. Therefore, it flows into the cold air suction port 132 formed on one side of the upper end of the main body 120 of the dedicated storage container 100 through the flow path outlet (72).

The cold air flows along the main body passage 130 formed between the inner wall 122 and the outer wall 124 of the main body 120 of the exclusive storage container 100 to keep the kimchi stored in a fresher state and the cold air outlet 134 You will exit through.

In the state in which the dedicated storage container 100 is not installed, all of the cold air discharge membranes 74 formed on each flow path outlet 72 of the dedicated storage container flow path 70 are blocked by the elasticity of the spring 74a itself. Since the cold air is not transmitted through the flow path outlet 72, the cold air flows out only through the refrigerating chamber interruption flow path 60 and the crissing room flow path 40 as in the related art.

Meanwhile, in the above description, the kimchi is described as an example, but is not limited thereto. That is, foods sensitive to temperature changes or foods that need to be kept at a low temperature may be stored in the dedicated storage container to achieve the same purpose.

As described above, there is an effect that the kimchi can always be kept in a fresh state for a long time by the structure of the refrigerating chamber flow path of the refrigerator and the storage container for kimchi according to the present invention.

Another benefit is that foods sensitive to temperature changes can always be kept fresh.
