Cold air circulation system of the refrigerator

The present invention relates to a cold air circulation device of a refrigerator that circulates cold air generated in an evaporator into a refrigerator, and in particular, the cold air circulated through the kimchi chamber is supplied directly to the kimchi chamber without the cold air generated in the evaporator entering the refrigerating chamber. It relates to a cold air circulation device of the refrigerator to be directly recovered by the evaporator.

In general, the refrigerator is formed by partitioning the refrigerator compartment 2 for storing and storing the frozen food and the freezing compartment 1 for storing the frozen food by the partition wall 3 as shown in FIGS. 1 and 2. The rear of the freezing chamber 1 is equipped with a circulation fan (F) to circulate the cold air generated by the evaporator (7), the refrigerating chamber (2) is a special chamber 6 and kimchi for storing and storing fish and meat It is divided into a kimchi room (4) for storing and storing and a vegetable room (5) for storing and storing vegetables.

The cold air circulation device of the refrigerator configured as described above is configured such that the cold air generated in the evaporator 7 is distributed and supplied to the refrigerating chamber 2 and the freezing chamber 1 by the circulation fan F.

That is, the cold air circulation device of the refrigerator includes a cold air supply duct 10 and a freezer compartment cold air outlet 10a for guiding the cold air so that the cold air generated in the evaporator 7 is supplied to the freezing chamber 1, and the evaporator 7 ) Has a refrigerator compartment connection duct (11) for guiding the flow of cold air to be supplied to the refrigerator compartment (2), and the refrigerator compartment outlet ducts (12a) of the upper and lower stages, and the refrigerator compartment connection duct (11) The refrigerating chamber cold air supply duct 12 in communication with the special chamber cold air supply duct 13 branched from the refrigerating chamber cold air supply duct 12 so that cold air is supplied to the special chamber 6; And a distribution duct 14 branched from the lower end of the refrigerating chamber cold air supply duct 12 so that cold air is supplied to the kimchi chamber 4 and the vegetable chamber 5.

In addition, the cold air circulation device circulates through the freezer compartment circulation duct 15 formed in the upper part of the separation wall 3 so that the cold air circulating in the freezer compartment 1 flows into the evaporator 7, the refrigerating compartment 2, and the like. The refrigerator compartment circulation duct 16 formed in the lower part of the partition wall 3 so that the cold air flows into the evaporator 7, and the inside of the refrigerator compartment cold air supply duct 12 are installed inside the refrigerator compartment 2 and the specialty. A refrigerator compartment damper (D) for adjusting the amount of cold air supplied to the chamber (6), and a branch duct (14) in the direction of the kimchi chamber (4) at the lower end of the refrigerator compartment supply duct (12) and having a handle (43) Kimchi chamber damper (42).

In the conventional cold air circulation device configured as described above, a part of the cold air heat exchanged through the evaporator 7 by the operation of the circulation fan (F) through the freezer compartment cold air outlet 10a of the freezer compartment cold air supply duct 10. After being supplied to the freezer compartment 1, the food stored in the freezer compartment 1 is frozen and then circulated to the evaporator 7 via the freezer compartment circulation duct 15.

In addition, the other part of the cold air heat exchanged through the evaporator 7 is supplied to the refrigerating chamber cold air supply duct 12 along the refrigerating chamber connecting duct 11, and then the special chamber cold air supply duct 13 and the special chamber cold air discharge outlet ( 13a) is fed to the specialty chamber (6) to refrigerated food such as fish and meat, and is supplied to the refrigerator compartment (2) through each refrigerator compartment refrigerator outlet (12a) to refrigerated food placed on the shelf (20) Let's do it.

In addition, the cold air supplied to the distribution duct 14 at the bottom of the refrigerating chamber cold air supply duct 12 refrigeration of the vegetables stored in the vegetable chamber 5 and at the same time to store the kimchi stored in the kimchi chamber 4 refrigerated. do.

In addition, the cold air supplied to the special chamber 6, the vegetable chamber 5 and the kimchi chamber 4 is evaporator along the refrigerator compartment circulation duct 16 formed in the partition wall 3 in a state combined with the cold of the refrigerator compartment 2; Circulated to (7).

On the other hand, when the kimchi stored in the kimchi container 40 of the kimchi chamber 4 is in the fermentation stage, the kimchi chamber damper 42 blocks the distribution duct 14 in communication with the kimchi chamber 4 by operating the handle 43. At the same time the cold air is not introduced into the kimchi chamber (4) and the heat transfer heater 41 embedded in the kimchi container 40 is operated to make the kimchi fermentation.

In addition, when the kimchi fermentation is completed and the handle 43 is operated to switch to the storage step, the operation of the electric heater 41 is stopped, and the cold air is supplied to the kimchi chamber 4 by opening the damper 42. .

In addition, when the fermentation of the kimchi stored in the kimchi chamber (4) is finished and enters the storage step, the kimchi chamber (4) is supplied to the cold air (about 2 ℃) of a constant temperature without interruption of the kimchi taste in a state that is almost not fermented. It should be refrigerated fresh for a long time so as not to change.

However, since the conventional refrigerator air circulation device is branched from the refrigerating chamber cold air supply duct 12 to the special chamber cold air supply duct 13 and the distribution duct 14, when the refrigerator compartment damper D is blocked, the refrigerating compartment 2 There was a problem that the supply of cold air to the kimchi room (4) as well as the specialty room (6) and the vegetable room (5).

That is, when the refrigerating temperature of the refrigerating compartment 2 falls below the set value in the state where the kimchi chamber damper 42 is opened, the refrigerating compartment damper D is automatically cut off according to the set program of the microcomputer to lower the refrigerating compartment 2 temperature. Since it prevents, the cold air is not supplied to the kimchi room (4), the kimchi room temperature rises naturally, according to the fermentation of kimchi proceeds and the kimchi taste is altered.

Therefore, there was a problem that the kimchi storage period is shortened.

Also, according to our dietary culture, we consume more vegetables than fish or meat.

And nowadays, vegetables are preferred over meat because of concern about adult diseases.

Therefore, the amount of vegetable storage is naturally higher than that of fish or meat. In the conventional cold air circulation system, the special chamber 6 is provided on the upper side of the refrigerating chamber 2, and the vegetable chamber 5 is provided side by side with the kimchi chamber 4. Because they could not store more vegetables.

In addition, according to the frequency of use, the number of times of using the vegetable chamber 5 is higher than the special chamber 6, the vegetable chamber 5 is provided in the lower part of the refrigerating chamber 2, there was an inconvenience to bend a lot to use it.

In addition, the heat transfer heater 41 is operated during the kimchi fermentation in the fraudulent kimchi chamber 4.

Since the heat heater 41 is embedded in the kimchi container 40 made of a heat insulating material, most of the heat is directed toward the kimchi, and when the operating time of the heat heater 41 is long, heat is radiated to the outside in the kimchi container 40. Radiant heat is naturally generated, and the radiant heat flows out into the refrigerating chamber 2 outside the kimchi chamber 4.

Therefore, the temperature of the refrigerating compartment 2 is increased, which may cause food to be stored in the refrigerating compartment 2 to be deteriorated, and as the smell of kimchi fermentation flows out into the refrigerating compartment 2 together, it permeates the stored food and smells of kimchi. There was a problem to remind.

That is, the conventional cold air circulation device of the refrigerator, the cold air of the kimchi room is introduced into the refrigerating chamber, there is a problem that the smell of kimchi permeates into food stored outside the kimchi room.

The present invention was made in view of the above-described problems, and an object of the present invention is to ensure that the cold air generated in the evaporator is directly supplied to the kimchi chamber without being introduced into the refrigerating chamber and the cold air circulated through the kimchi chamber is directly recovered to the evaporator. It is to provide a cold air circulation device of the refrigerator that can store the food stored in addition to kimchi room more fresh.
