- The present invention relates to a cold air circulating apparatus for use in a Kimchi refrigerator, and more specifically, to an apparatus for circulating cold air between storage compartments of a Kimchi refrigerator, which is capable of shortening the amount of time required to lower temperature inside the storage compartments to a preset temperature.
- In general, a Kimchi refrigerator is one of electric home appliances for exclusive use for Kimchi, which can mature and preserve Kimchi at its optimal taste using a cooling cycle. The Kimchi refrigerator serves to mature or season Kimchi at an optimum fermentation temperature that is variable according to a user's taste, and keep the matured Kimchi at an optimum storage temperature for an extended period of time.
- Such a Kimchi refrigerator is provided with a cooler and a door used for preventing chilled air provided by the cooler inside storage compartments from escaping to outside at the time of opening and closing of the door to make sure that the temperature inside the refrigerator is constantly maintained. The interior space of the Kimchi refrigerator is divided into two storage compartments: one may be used for preserving matured Kimchi in a temperature range of about −0.5° C. to 1° C., and the other for maturing Kimchi in a temperature range of about 5° C. to 7° C.; or else both for preserving or maturing the Kimchi.
- In addition, a drawer type storage compartment designed to pull and push horizontally may be provided in the lower portion of the storage compartments.
-
FIG. 1 is a perspective view showing a conventional Kimchi refrigerator provided with a cold air circulating apparatus, andFIG. 2 is an enlarged view of a cooling fan embedded into the door of the Kimchi refrigerator depicted inFIG. 1 . As shown in the drawings, the conventional Kimchi refrigerator 1 is provided with amain body 2 divided into an upper portion and a lower portion. In the upper portion of themain body 2, aleft storage compartment 3 and aright storage compartment 4 are formed, and in the lower portion of themain body 2, a drawertype storage compartment 5 that is slid in and out horizontally is formed. - Meanwhile, the Kimchi refrigerator 1 is further provided with, on its left and right sides of the upper portion, cold air circulating apparatuses for circulating cold air in the left and the

-
FIG. 3 is a perspective view showing a Kimchi refrigerator provided with a cold air circulating apparatus in accordance with the present invention, andFIG. 4 presents a plan view schematically illustrating a cold air circulating apparatus in a Kimchi refrigerator in accordance with the present invention. - As shown in the drawings, interior space of a Kimchi
refrigerator 100 is divided, by apartition wall 101 at the center, into aleft storage compartment 110 and aright storage compartment 120. The left and theright storage compartments storage compartment doors storage compartments -
Cooling fans left compartment door 111 and the rightstorage compartment door 121, respectively, to thereby circulate cold air inside the corresponding storage compartments. - A
control panel 160 is installed on a front of the Kimchirefrigerator 100 and serves to select preset temperatures for thestorage compartments - Further, formed inside the rear portion of the left and the
right storage compartments cooling unit 130 such as an evaporator for generating the cold air to refrigerate inside thestorage compartments - In addition, the left and the
right storage compartments temperature sensors corresponding compartments - Meanwhile, the
partition wall 101 dividing the interior space of the Kimchi refrigerator into the left and theright storage compartments communication passages communication passages communication passages electronic dampers communication passages - Moreover, as shown in
FIG. 5 which is a schematic block diagram showing the cold air circulating apparatus of the Kimchi refrigerator illustrated inFIGS. 3 and 4 , acontrol unit 170 is provided to control the circulation of the cold air. More specifically, thecontrol unit 170 receives the temperature detection signals from thetemperature sensors dampers - For the convenience of explanation hereinafter, among those two communication passages, the communication passage being disposed closer to the
evaporator 130 is referred to as afirst communication passage 140, and the other communication passage spaced apart from thefirst communication passage 140 by a designated distance is referred to as asecond communication passage 150. For the same purpose, the damper inside thefirst communication passage 140 is referred to as afirst damper 141, and the damper inside thesecond communication passage 150 is named asecond damper 151. - As described above, the
partition wall 101 has the first and thesecond communication passages right storage compartments dampers second communication passages - Therefore, in case where a current temperature inside the
left storage compartment 110 or theright storage compartment 120, being sensed by thetemperature sensor dampers second communication passages right storage compartments storage compartments cooling fans storage compartments - Preferably, the circulating apparatus further includes ventilating
fans second communication passages ventilating fans left storage compartment 110 and theright storage compartment 120 more efficiently. - It is more preferably that the
ventilating fans communication passages ventilating fans - Hereinafter, for the convenience of explanation, the ventilating fan on the left inner side of the
first communication passage 140 is named a firstventilating fan 142, and the ventilating fan on the right inner side is named a secondventilating fan 143. Similarly, the ventilating fan on the left inner side of thesecond communication passage 150 is named a thirdventilating fan 152, and the ventilating fan on the right inner side is named a fourthventilating fan 153. - Now, an operation of the cold air circulating apparatus for use in a Kimchi refrigerator in accordance with the invention will be described in detail with reference to the accompanying drawings.
-
FIGS. 6 and 7 are exemplary views illustrating the operations of a cold air circulating apparatus for use in a Kimchi refrigerator in accordance with the present invention. - In operation, current temperatures inside the left and the right storage compartments are detected by the
temperature sensors - If it is determined by the
control unit 170 that the current temperature in theright storage compartment 120 is higher than a preset temperature for theright storage compartment 120, and if it is also determined by thecontrol unit 170 that the current temperature in theright storage compartment 120 is higher than the current temperature detected by thetemperature sensor 162, thecontrol unit 170 outputs a driving control signal to open the first and thesecond dampers second communication passages FIG. 6 . - At the same time, under the control of the
control unit 170, thesecond ventilating fan 143 and thefourth ventilating fan 153 operate. Therefore, cold air from theleft storage compartment 110 flows into theright storage compartment 120 via thefirst communication passage 140, and cold air from theright storage compartment 120 flows into theleft storage compartment 110 via thesecond communication passage 150, to thereby circulate cold air between theleft storage compartment 110 and theright storage compartment 120. - The reason for operating the
second ventilating fan 143 is to cause the cold air to blow from theleft storage compartment 110 into theright storage compartment 120 via thefirst communication passage 140. That is, the cold air is circulated between the storage compartments in a direction that the cold air in theleft storage compartment 110 flows out into theright storage compartment 120 through thecommunication passage 140, thecommunication passage 140 being formed closer to theevaporator 130. - As a result, the coldest air existing in the vicinity of the
evaporator 130 in the interior space of theleft storage compartment 110 can flow directly and immediately into theright storage compartment 120, to thereby lower the temperature of theright storage compartment 120 more effectively. - In addition, it may be implemented in a manner that the cooling
fans storage compartment doors - During the above operation, if it is determined that the current temperature inside the
right storage compartment 120 is lowered to the preset temperature, thecontrol unit 170 controls the first and thesecond dampers fourth ventilating fans - Thereafter, the
Kimchi refrigerator 100 allows theleft storage compartment 110 and theright storage compartment 120 to be driven independently of each other. - On the other hand, if it is detected that current temperature in the
left storage compartment 110 is higher than a preset temperature for theleft storage compartment 110 and is also higher than current temperature in theright storage compartment 110, thecontrol unit 170 outputs a driving control signal to open the first and thesecond dampers second communication passages - At the same time, the
first ventilating fan 142 and thethird ventilating fan 152 operate, and therefore, cold air from theright storage compartment 120 forces to blow into theleft storage compartment 110 via thefirst communication passage 140, and cold air from theleft storage compartment 110 forces to blow into theright storage compartment 120 via thesecond communication passage 150, as shown inFIG. 7 , thereby circulating cold air between theleft storage compartment 110 and theright storage compartment 120. - The reason for causing the cold air to flow from the
right storage compartment 120 into theleft storage compartment 110 via thefirst communication passage 140 is that the coldest air existing in the vicinity of theevaporator 130 in the interior space of theright storage compartment 120 can flow into theleft storage compartment 110 to thus lower the temperature of theleft storage compartment 110 more effectively. That is, the cold air is circulated between the storage compartments in a direction that the cold air in theright storage compartment 120 blows out into theleft storage compartment 110 through thecommunication passage 140 closer to theevaporator 130. - In addition, it may be implemented in a manner that the cooling
fans storage compartment doors - Thereafter, under the control of the
control unit 170, if it is determined that the temperature inside theleft storage compartment 110 is lowered to the preset temperature, the first and thesecond dampers third ventilating fans left storage compartment 110 and theright storage compartment 120 to be refrigerated independently of each other. - Although it has been illustrated and disclosed that the ventilating
fans second communication passages second communication passages 140, respectively. - Therefore, in
FIG. 6 , a first DC ventilating fan installed in thefirst communication passage 140 instead thesecond ventilating fan 143 forces cold air from theleft storage compartment 110 to blow into theright storage compartment 120, and a second DC fan installed in thesecond communication passage 150 instead thefourth ventilating fan 153 forces cold air from theright storage compartment 120 to blow into theleft storage compartment 110, thereby circulating cold air between theleft storage compartment 110 and theright storage compartment 120. - Meanwhile, in
FIG. 7 , a first DC ventilating fan installed in thefirst communication passage 140 instead thefirst ventilating fan 142 forces cold air from theright storage compartment 120 forces to blow into theleft storage compartment 110, and a second DC ventilating fan installed in thesecond communication passage 150 instead thethird ventilating fan 152 forces cold air from theleft storage compartment 110 cold air from theleft storage compartment 110 forces to blow into theright storage compartment 120, thereby circulating cold air between theleft storage compartment 110 and theright storage compartment 120. - Alternatively, there may be several countermeasures on how to install the ventilating fans. One of the countermeasures is to install a ventilating fan in any one of the communication passage, e.g., the
first communication passage 140. The ventilating fan is a DC type fan and is controlled to selectively change the direction of air flow in bi-direction. - Another countermeasure is to install each AC fan in each communication passage instead of pairs of AC fans, respectively.
- As explained so far, the cold air circulating apparatus for use in a Kimchi refrigerator according to the present invention is provided with the first and the second communication passages capable of making the left and right storage compartments communicate with each other, and the first and the second dampers capable of selectively opening or closing the first and the second communication passages. Therefore, if temperature inside the left storage compartment is higher than the preset temperature, cold air flows from the right storage compartment into the left storage compartment, while if temperature inside the right storage compartment is higher than the preset temperature, cold air flows from the left storage compartment into the right storage compartment. In this manner, cold air inside each storage compartment is circulated more effectively, thereby shortening the amount of time required to lower temperature of cold air down to the preset temperature.
- While the invention has been shown and described with respect to the preferred embodiments, it will be understood by those skilled in the art that various changes and modification may be made without departing from the scope of the invention as defined in the following claims.
