Description

本発明はキムチ冷蔵庫の冷気循環装置に関し、より詳しくは、キムチ冷蔵庫の貯蔵室間で冷気が互いに循環するようにして貯蔵室内の温度を設定温度まで下げるのに必要な時間を短縮できるキムチ冷蔵庫の冷気循環装置に関する。   The present invention relates to a cold air circulation device for a kimchi refrigerator, and more particularly, to a kimchi refrigerator capable of reducing the time required for lowering the temperature in a storage room to a set temperature by circulating cold air between the storage rooms of the kimchi refrigerator. The present invention relates to a cold air circulation device.

一般に、キムチ冷蔵庫は、キムチ専用の家電製品の１つであり、冷凍サイクルを用いてキムチを最高の味で保存及び熟成させることができる。ユーザの好みによってキムチを最適の熟成温度で熟成させた後、最適の保存温度でキムチを長期間持続的に保存できるようにする。   Generally, a kimchi refrigerator is one of the home appliances dedicated to kimchi, and can be stored and aged with the best taste using a refrigeration cycle. After kimchi is ripened at an optimal aging temperature according to user's preference, kimchi can be stored continuously for a long period of time at an optimal storage temperature.

このようなキムチ冷蔵庫には、冷却器と、冷蔵庫内の温度を確実に一定に維持するように貯蔵室内の冷却器により生成された冷気が貯蔵室を開閉する際に外部に流出しないようにするためのドアとが装着される。また、貯蔵室の内部空間は２つの貯蔵室に区画され、一方は熟成されたキムチを約−０.５℃ないし１℃程度の温度で保存するために用いられ、他方はキムチを約５℃ないし７℃の温度で熟成させるために用いられ、あるいは両方がキムチの熟成又は保存に用いられることがある。   Such a kimchi refrigerator prevents the cool air generated by the cooler and the cooler in the storage chamber from flowing out when the storage chamber is opened and closed so as to ensure that the temperature in the refrigerator is kept constant. And a door for mounting. In addition, the interior space of the storage room is divided into two storage rooms, one is used to store aged kimchi at a temperature of about -0.5 ° C to 1 ° C, and the other is about 5 ° C. It can be used for aging at temperatures up to 7 ° C, or both can be used for ripening or storing kimchi.

また、貯蔵室の下部には、水平に開閉できるように別途の引出し式貯蔵室を備えることもできる。   In addition, a separate drawer-type storage chamber can be provided at the bottom of the storage chamber so that the storage chamber can be opened and closed horizontally.

図１は、冷気循環装置を有する従来のキムチ冷蔵庫を示す斜視図であり、図２は、図１に示したキムチ冷蔵庫のドア内部に装着される冷却ファンの拡大図である。図のように、従来のキムチ冷蔵庫１には、上部側と下部側とに分けられた本体２が備わっている。本体２の上部側には左側貯蔵室３及び右側貯蔵室４がそれぞれ形成されており、本体２の下部側には水平方向に開閉できるように引出し式貯蔵室５が形成されている。   FIG. 1 is a perspective view showing a conventional kimchi refrigerator having a cold air circulation device, and FIG. 2 is an enlarged view of a cooling fan mounted inside the door of the kimchi refrigerator shown in FIG. As shown in the figure, the conventional kimchi refrigerator 1 includes a main body 2 divided into an upper side and a lower side. A left storage chamber 3 and a right storage chamber 4 are formed on the upper side of the main body 2, and a drawer-type storage chamber 5 is formed on the lower side of the main body 2 so as to be opened and closed in the horizontal direction.

一方、キムチ冷蔵庫１には、上部の左側貯蔵室３及び右側貯蔵室４の冷気を循環させるために左側及び右側にそれぞれ１つの冷気循環装置が設置される。冷気循環装置は、それぞれ本体２に突出するように埋設され、電源（図示せず）に連結されているプッシュスイッチ７と、左側貯蔵室３（又は右側貯蔵室４）の冷気を下方に通風するようにドア６の底面に埋設される冷却ファン８と、冷却ファン８の動作を制御するための制御部（図示せず）とで構成される。   On the other hand, in the kimchi refrigerator 1, in order to circulate the cold air in the upper left storage chamber 3 and the right storage chamber 4, one cold air circulation device is installed on each of the left and right sides. The cold air circulation devices are respectively embedded in the main body 2 so as to protrude from the push switch 7 connected to a power source (not shown) and cool air in the left storage chamber 3 (or the right storage chamber 4). Thus, the cooling fan 8 embedded in the bottom surface of the door 6 and a control unit (not shown) for controlling the operation of the cooling fan 8 are configured.

冷却ファン８は、図２に示すように、ドア６の下段面に位置する空間９に挿入され、ボルトで締結され、そして通気口１０が形成されたカバー１１で覆われている。冷却ファン８は、プッシュスイッチ７に電気的に連結されている。冷却ファンは、ドア６が開放されてプッシュスイッチ７がターンオン状態である時、既定時間だけ動作し、そうでなければ、ドア６が閉じられてスイッチ７がターンオフ状態である時にその動作を停止する。   As shown in FIG. 2, the cooling fan 8 is inserted into a space 9 positioned on the lower surface of the door 6, fastened with a bolt, and covered with a cover 11 in which a vent hole 10 is formed. The cooling fan 8 is electrically connected to the push switch 7. The cooling fan operates for a predetermined time when the door 6 is opened and the push switch 7 is turned on, otherwise it stops operating when the door 6 is closed and the switch 7 is turned off. .

しかしながら、上記のような従来のキムチ冷蔵庫の冷気循環装置において、冷凍サイクルは、左側貯蔵室３と右側貯蔵室４で独立して別々の貯蔵空間で行われる。従って、ユーザがいずれか一方の貯蔵室の温度を下げなければならない場合に、ユーザは冷却のために対応する貯蔵室に設置された冷却ファン８のみを駆動させる。   However, in the cold air circulation device of the conventional Kimchi refrigerator as described above, the refrigeration cycle is performed in separate storage spaces in the left storage chamber 3 and the right storage chamber 4 independently. Therefore, when the user has to lower the temperature of one of the storage rooms, the user drives only the cooling fan 8 installed in the corresponding storage room for cooling.

この場合に、対応する貯蔵室を個別に冷却するために多くの時間がかかる。   In this case, it takes a lot of time to individually cool the corresponding storage chamber.

従って、本発明は上記事情に鑑みてなされたものであって、その目的は、２つ以上の貯蔵室を有するキムチ冷蔵庫において貯蔵室間で冷気が循環し得るようにしたキムチ冷蔵庫用冷気循環装置を提供することにある。   Accordingly, the present invention has been made in view of the above circumstances, and the object thereof is a cold air circulation device for a kimchi refrigerator that allows cold air to circulate between the storage rooms in a kimchi refrigerator having two or more storage rooms. Is to provide.

本発明の他の目的は、このようなキムチ冷蔵庫に含まれる貯蔵室内の温度を下げるのに必要な時間を短縮するようにした冷気循環装置を提供することにある。   Another object of the present invention is to provide a cold air circulation device that shortens the time required to lower the temperature in the storage chamber included in such a kimchi refrigerator.

上記目的を達成するための本発明の一実施形態によれば、隔壁により仕切られた少なくとも２つの貯蔵室を有するキムチ冷蔵庫に用いるための冷気循環装置が提供され、冷気循環装置は、各貯蔵室の現在温度を検知するための温度センサと、隔壁内で互いに所定間隔離間するように形成された１対の連通通路と、連通通路内に取り付けられた、連通通路を選択的に開閉するためのダンパと、温度センサによって検出された貯蔵室間の温度差に関する情報に基づいてダンパを開閉するための制御信号を出力するための制御部とを含む。   According to one embodiment of the present invention for achieving the above object, there is provided a cold air circulation device for use in a Kimchi refrigerator having at least two storage rooms partitioned by a partition wall, and the cold air circulation device is provided for each storage room. A temperature sensor for detecting the current temperature of the gas, a pair of communication passages formed so as to be spaced apart from each other within the partition wall, and selectively opening and closing the communication passages mounted in the communication passage A damper and a control unit for outputting a control signal for opening and closing the damper based on information on a temperature difference between the storage chambers detected by the temperature sensor are included.

従って、各貯蔵室内の冷気はより効果的に循環し、これにより、冷気の温度を設定温度以下に下げるのに必要な時間を短縮できるという効果を奏する。   Therefore, the cool air in each storage chamber circulates more effectively, thereby reducing the time required to lower the cool air temperature below the set temperature.

以下、添付図面を参照して、本発明によるキムチ冷蔵庫の冷気循環装置の好適な実施例を説明する。   Hereinafter, a preferred embodiment of a cold air circulation device of a kimchi refrigerator according to the present invention will be described with reference to the accompanying drawings.

図３は、本発明による冷気循環装置を備えたキムチ冷蔵庫を示す斜視図であり、図４は、本発明によるキムチ冷蔵庫の冷気循環装置を概略的に示す平面構成図である。   FIG. 3 is a perspective view showing a kimchi refrigerator equipped with a cold air circulation device according to the present invention, and FIG. 4 is a plan view schematically showing the cold air circulation device of the kimchi refrigerator according to the present invention.

図のように、キムチ冷蔵庫１００の内部空間は、中央の隔壁１０１によって、左側貯蔵室１１０及び右側貯蔵室１２０に分けられている。左側貯蔵室１１０及び右側貯蔵室１２０は、左側貯蔵室１１０及び右側貯蔵室１２０の内部を密閉するために設けられた左側貯蔵室ドア１１１及び右側貯蔵室ドア１２１によって上からそれぞれ覆われている。   As illustrated, the internal space of the kimchi refrigerator 100 is divided into a left storage chamber 110 and a right storage chamber 120 by a central partition wall 101. The left storage chamber 110 and the right storage chamber 120 are respectively covered from above by a left storage chamber door 111 and a right storage chamber door 121 provided to seal the inside of the left storage chamber 110 and the right storage chamber 120.

左側貯蔵室ドア１１１及び右側貯蔵室ドア１２１にはそれぞれ冷却ファン１１２、１２２が埋め込まれ、それによって、対応する貯蔵室の内部で冷気が循環するようにしている。   Cooling fans 112 and 122 are embedded in the left storage chamber door 111 and the right storage chamber door 121, respectively, so that cool air circulates in the corresponding storage chamber.

制御パネル１６０がキムチ冷蔵庫１００の前面に設置され、貯蔵室１１０、１２０の設定温度を選択するように機能する。   A control panel 160 is installed in front of the kimchi refrigerator 100 and functions to select a set temperature of the storage chambers 110 and 120.

また、貯蔵室１１０、１２０内を冷却するために冷気を生成するための蒸発器などの冷却器１３０が、キムチ冷蔵庫１００の左側貯蔵室１１０及び右側貯蔵室１２０の背面内部に形成されている。   Further, a cooler 130 such as an evaporator for generating cool air to cool the inside of the storage chambers 110 and 120 is formed inside the back surface of the left storage chamber 110 and the right storage chamber 120 of the Kimchi refrigerator 100.

更に、左側貯蔵室１１０及び右側貯蔵室１２０の内部には、それぞれ、温度センサ１６２、１６３が装着され、温度センサ１６２、１６３は左側貯蔵室１１０及び右側貯蔵室１２０内部の現在温度を検知し、現在温度を示す温度検出信号を生成する。   Furthermore, temperature sensors 162 and 163 are installed in the left storage chamber 110 and the right storage chamber 120, respectively, and the temperature sensors 162 and 163 detect the current temperatures inside the left storage chamber 110 and the right storage chamber 120, respectively. A temperature detection signal indicating the current temperature is generated.

一方、キムチ冷蔵庫の内部を左側貯蔵室１１０及び右側貯蔵室１２０に分ける隔壁１０１の内部には、互いに水平方向に離間する１対の連通通路１４０、１５０が形成されている。あるいは、連通通路１４０、１５０は、垂直方向に配列されることもできる。連通通路１４０、１５０内には、連通通路１４０、１５０を選択的に開閉するように動作可能な電子式ダンパ１４１、１５１が組み込まれている。   On the other hand, a pair of communication passages 140 and 150 are formed in the partition wall 101 that divides the interior of the kimchi refrigerator into a left storage chamber 110 and a right storage chamber 120 that are spaced apart from each other in the horizontal direction. Alternatively, the communication passages 140 and 150 can be arranged in the vertical direction. Electronic dampers 141 and 151 operable to selectively open and close the communication paths 140 and 150 are incorporated in the communication paths 140 and 150.

また、図３及び図４に示したキムチ冷蔵庫の冷気循環装置を示す概略的なブロック図である図５に示すように、冷気の循環を制御するために制御部１７０が設けられている。具体的には、制御部１７０は、温度センサ１６２、１６３から温度検出信号を受信し、ダンパ１４１、１５１を開閉するための駆動制御信号を出力する。   Further, as shown in FIG. 5, which is a schematic block diagram showing the cold air circulation device of the kimchi refrigerator shown in FIGS. 3 and 4, a control unit 170 is provided for controlling the circulation of the cold air. Specifically, the control unit 170 receives temperature detection signals from the temperature sensors 162 and 163 and outputs drive control signals for opening and closing the dampers 141 and 151.

以下、説明の便宜上、２つの連通通路のうち、蒸発器１３０のより近くに配置されている連通通路を第１連通通路１４０、第１連通通路１４０から所定間隔離間している連通通路を第２連通通路１５０と呼ぶ。同じ目的で、第１連通通路１４０内のダンパを第１ダンパ１４１と呼び、第２連通通路１５０内のダンパを第２ダンパ１５１と名付ける。   Hereinafter, for convenience of explanation, of the two communication passages, the communication passage disposed closer to the evaporator 130 is the first communication passage 140, and the communication passage that is separated from the first communication passage 140 by a predetermined distance is the second communication passage. This is called a communication passage 150. For the same purpose, the damper in the first communication path 140 is called a first damper 141, and the damper in the second communication path 150 is named a second damper 151.

上記のように、隔壁１０１は、その内部に第１連通通路１４０及び第２連通通路１５０が形成されている。それゆえ、左側貯蔵室１１０及び右側貯蔵室１２０は、それぞれ第１連通通路１４０及び第２連通通路１５０に取り付けられたダンパ１４１、１５１により選択的に連通される。   As described above, the partition wall 101 has the first communication passage 140 and the second communication passage 150 formed therein. Therefore, the left storage chamber 110 and the right storage chamber 120 are selectively communicated by dampers 141 and 151 attached to the first communication passage 140 and the second communication passage 150, respectively.

従って、温度センサ１６２、１６３によって検知される左側貯蔵室１１０又は右側貯蔵室１２０内の現在温度が、その中でキムチを保存するための設定温度より高い場合、ダンパ１４１、１５１は、第１連通通路１４０及び第２連通通路１５０を開放するように操作される。これにより、左側貯蔵室１１０及び右側貯蔵室１２０内の冷気が互いに混ざり合い、対象貯蔵室の温度より低い別の貯蔵室の冷気を用いて対象貯蔵室の温度を下げることによって、両貯蔵室内の温度をほぼ等しくする。これにより、従来技術のように貯蔵室１１０、１２０に取り付けられた冷却ファン１１２、１２２を個別に駆動することによって貯蔵室１１０及び１２０のそれぞれの温度を下げるよりは、対象温度を設定温度まで下げるのに要する時間を短縮することが成し遂げられる。   Accordingly, when the current temperature in the left storage chamber 110 or the right storage chamber 120 detected by the temperature sensors 162 and 163 is higher than the set temperature for storing kimchi therein, the dampers 141 and 151 are connected to the first communication chamber. The passage 140 and the second communication passage 150 are operated to be opened. Accordingly, the cold air in the left storage chamber 110 and the right storage chamber 120 mixes with each other, and the temperature of the target storage chamber is lowered by using the cold air of another storage chamber lower than the temperature of the target storage chamber. Make the temperature approximately equal. As a result, the target temperature is lowered to the set temperature rather than lowering the respective temperatures of the storage chambers 110 and 120 by individually driving the cooling fans 112 and 122 attached to the storage chambers 110 and 120 as in the prior art. A reduction in the amount of time required is achieved.

循環装置は、第１連通通路１４０及び第２連通通路１５０の左側及び右側に作動的に対向して取り付けられた通風ファン１４２、１４３及び１５２、１５３をさらに含むのが好ましい。通風ファン１４２、１４３及び１５２、１５３は、左側貯蔵室１１０と右側貯蔵室１２０との間の冷気の循環をより効果的に促進する。   The circulation device preferably further includes ventilation fans 142, 143 and 152, 153 operatively opposed to the left and right sides of the first communication passage 140 and the second communication passage 150. The ventilation fans 142, 143 and 152, 153 more effectively promote the circulation of cold air between the left storage chamber 110 and the right storage chamber 120.

通風ファン１４２、１４３、１５２、１５３は、空気が連通通路１４０及び１５０の内部から外部に通気するように取り付けられるのがより好ましい。このような通風ファン１４２、１４３、１５２、１５３は、一方向に冷気を吹き込むＡＣファンにより実現されることもできる。   The ventilation fans 142, 143, 152, and 153 are more preferably attached so that air is vented from the inside of the communication passages 140 and 150 to the outside. Such ventilation fans 142, 143, 152, and 153 can also be realized by AC fans that blow cool air in one direction.

以下、説明の便宜上、第１連通通路１４０の左内側の通風ファンを第１通風ファン１４２、右内側の通風ファンを第２通風ファン１４３と名付け、第２連通通路１５０の左内側の通風ファンを第３通風ファン１５２、右内側の通風ファンを第４通風ファン１５３と名付ける。   Hereinafter, for convenience of explanation, the left inner ventilation fan of the first communication passage 140 is named the first ventilation fan 142, the right inner ventilation fan is named the second ventilation fan 143, and the left inner ventilation fan of the second communication passage 150 is named. The third ventilation fan 152 and the right inner ventilation fan are named the fourth ventilation fan 153.

ここで、添付図面を参照して、本発明によるキムチ冷蔵庫に用いるための冷気循環装置の動作を説明する。   Here, with reference to the accompanying drawings, the operation of the cold air circulation device for use in the kimchi refrigerator according to the present invention will be described.

図６及び図７は、本発明によるキムチ冷蔵庫に用いるための冷気循環装置の作動例を示す説明図である。   6 and 7 are explanatory views showing an operation example of the cold air circulation device for use in the kimchi refrigerator according to the present invention.

動作時に、左側貯蔵室１１０及び右側貯蔵室１２０内に取り付けられている温度センサ１６２、１６３により、左側及び右側貯蔵室の現在温度がそれぞれ検出される。   In operation, the temperature sensors 162 and 163 attached in the left storage chamber 110 and the right storage chamber 120 detect the current temperatures of the left and right storage chambers, respectively.

もし、右側貯蔵室１２０の現在温度が右側貯蔵室１２０に対する設定温度よりも高いと制御部１７０によって判定され、かつ、右側貯蔵室１２０の現在温度が温度センサ１６２により検知された現在温度よりも高いと制御部１７０によって判定されるならば、制御部１７０は、駆動制御信号を出力して第１ダンパ１４１及び第２ダンパ１５１を開放し、それによって、図６に示すように、第１連通通路１４０及び第２連通通路１５０の両方を開放する。   If the current temperature of the right storage chamber 120 is higher than the set temperature for the right storage chamber 120, the controller 170 determines that the current temperature of the right storage chamber 120 is higher than the current temperature detected by the temperature sensor 162. , The controller 170 outputs a drive control signal to open the first damper 141 and the second damper 151, thereby, as shown in FIG. 6, the first communication path. Both 140 and the second communication passage 150 are opened.

同時に、制御部１７０の制御の下で、第２通風ファン１４３及び第４通風ファン１５３が作動する。それゆえ、左側貯蔵室１１０からの冷気は第１連通通路１４０を介して右側貯蔵室１２０に流入し、右側貯蔵室１２０からの冷気は第２連通通路１５０を介して左側貯蔵室１１０に流入し、それによって、左側貯蔵室１１０と右側貯蔵室１２０との間で冷気を循環させる。   At the same time, the second ventilation fan 143 and the fourth ventilation fan 153 are operated under the control of the control unit 170. Therefore, the cold air from the left storage chamber 110 flows into the right storage chamber 120 through the first communication passage 140, and the cold air from the right storage chamber 120 flows into the left storage chamber 110 through the second communication passage 150. Thereby, cold air is circulated between the left storage chamber 110 and the right storage chamber 120.

第２通風ファン１４３を駆動させる理由は、冷気を、左側貯蔵室１１０から第１連通通路１４０を介して右側貯蔵室１２０に通気させるためである。即ち、冷気は、左側貯蔵室１１０の冷気が連通通路１４０を介して右側貯蔵室１２０に流れる方向に、貯蔵室間で循環される。連通通路１４０は、蒸発器１３０のより近くに形成されている。   The reason for driving the second ventilation fan 143 is to allow cool air to flow from the left storage chamber 110 to the right storage chamber 120 through the first communication passage 140. That is, the cold air is circulated between the storage chambers in such a direction that the cold air in the left storage chamber 110 flows into the right storage chamber 120 via the communication passage 140. The communication passage 140 is formed closer to the evaporator 130.

その結果、左側貯蔵室１１０の内部空間において蒸発器１３０の近くに存在する最も冷たい空気は、右側貯蔵室１２０に直接かつ直ちに流入することができ、それによって、右側貯蔵室１２０の温度をより効果的に下げる。   As a result, the coldest air present near the evaporator 130 in the interior space of the left storage chamber 110 can flow directly and immediately into the right storage chamber 120, thereby making the temperature of the right storage chamber 120 more effective. Lower.

また、左側貯蔵室ドア１１１及び右側貯蔵室ドア１２１に埋め込まれている冷却ファン１１２、１２２が協働し、それによって冷気が垂直方向にも循環するように実現されることもできる。   In addition, the cooling fans 112 and 122 embedded in the left storage door 111 and the right storage door 121 may cooperate to thereby circulate cold air in the vertical direction.

前述した動作中に、右側貯蔵室１２０内の現在温度が設定温度まで低下したと判定されたら、制御部１７０は、第１ダンパ１４１及び第２ダンパ１５１を制御して閉じさせ、第２通風ファン１４３及び第４通風ファン１５３を制御して動きを止める。   If it is determined that the current temperature in the right storage chamber 120 has decreased to the set temperature during the above-described operation, the control unit 170 controls the first damper 141 and the second damper 151 to close, and the second ventilation fan. 143 and the 4th ventilation fan 153 are controlled, and a motion is stopped.

その後、キムチ冷蔵庫１００は、左側貯蔵室１１０及び右側貯蔵室１２０の互いに独立した駆動を可能にする。   Thereafter, the kimchi refrigerator 100 allows the left storage chamber 110 and the right storage chamber 120 to be driven independently of each other.

一方、左側貯蔵室１１０の現在温度が左側貯蔵室に対する設定温度よりも高いことが検出されかつ右側貯蔵室１２０の現在温度よりも高いならば、制御部１７０は、駆動制御信号を出力して第１ダンパ１４１及び第２ダンパ１５１を開放し、それによって、第１連通通路１４０及び第２連通通路１５０を開放する。   On the other hand, if it is detected that the current temperature of the left storage chamber 110 is higher than the set temperature for the left storage chamber and is higher than the current temperature of the right storage chamber 120, the controller 170 outputs a drive control signal to The first damper 141 and the second damper 151 are opened, and thereby the first communication path 140 and the second communication path 150 are opened.

同時に、第１通風ファン１４２及び第３通風ファン１５２が動作し、その結果、図７に示すように、右側貯蔵室１２０からの冷気を強制的に第１連通通路１４０を介して左側貯蔵室１１０に流入させ、左側貯蔵室１１０の冷気を強制的に第２連通通路１５０を介して右側貯蔵室１２０に流入させ、それによって左側貯蔵室１１０と右側貯蔵室１２０との間で冷気を循環させる。   At the same time, the first ventilation fan 142 and the third ventilation fan 152 are operated. As a result, as shown in FIG. 7, the left storage chamber 110 is forced to cool air from the right storage chamber 120 through the first communication passage 140. The cold air in the left storage chamber 110 is forced to flow into the right storage chamber 120 through the second communication passage 150, thereby circulating the cold air between the left storage chamber 110 and the right storage chamber 120.

冷気を右側貯蔵室１２０から第１連通通路１４０を介して左側貯蔵室１１０に流入させる理由は、右側貯蔵室１２０の内部空間において蒸発器１３０の近くに存在する最も冷たい空気は、左側貯蔵室１１０に流入することができ、それゆえ、左側貯蔵室１１０の温度をより効果的に下げるからである。即ち、冷気は、右側貯蔵室１２０の冷気が、蒸発器１３０により近い連通通路１４０を介して左側貯蔵室１１０内へ吹き出る方向に、貯蔵室間で循環される。   The reason why the cool air flows into the left storage chamber 110 from the right storage chamber 120 through the first communication passage 140 is that the coolest air existing near the evaporator 130 in the inner space of the right storage chamber 120 is the left storage chamber 110. This is because the temperature of the left storage chamber 110 can be lowered more effectively. That is, the cold air is circulated between the storage chambers in such a direction that the cold air in the right storage chamber 120 blows out into the left storage chamber 110 through the communication passage 140 closer to the evaporator 130.

また、左側貯蔵室ドア１１１及び右側貯蔵室ドア１２１に埋め込まれている冷却ファン１１２、１２２が協働し、それによって冷気が垂直方向にも循環するように実現されることもできる。このことは、貯蔵室内の冷気のより効果的な循環をもたらす。   In addition, the cooling fans 112 and 122 embedded in the left storage door 111 and the right storage door 121 may cooperate to thereby circulate cold air in the vertical direction. This provides a more effective circulation of cool air in the storage chamber.

その後、制御部１７０の制御下で、左側貯蔵室１１０内部の温度が設定温度まで低下したと判定されたら、第１ダンパ１４１及び第２ダンパ１５１が閉じられ、第１通風ファン１４２及び第３通風ファン１５２は動きを止め、それによって、左側貯蔵室１１０及び右側貯蔵室１２０の互いに独立して冷却されることが可能になる。   Thereafter, when it is determined that the temperature inside the left storage chamber 110 has decreased to the set temperature under the control of the control unit 170, the first damper 141 and the second damper 151 are closed, and the first ventilation fan 142 and the third ventilation are closed. The fan 152 stops moving, thereby allowing the left storage chamber 110 and the right storage chamber 120 to be cooled independently of each other.

通風ファン１４２、１４３及び１５２、１５３は第１連通通路１４０及び第２連通通路１５０の左右にそれぞれ取り付けられたＡＣタイプの通風ファンであると例示しかつ説明してきたが、ＡＣタイプの通風ファンを、気流の方向を選択的に両方向に変えることができるＤＣタイプの通風ファンに替えることも可能である。この場合、ＤＣタイプの通風ファン１台を第１連通通路１４０及び第２連通通路１５０にそれぞれ取り付けるだけでも十分である。   The ventilation fans 142, 143 and 152, 153 have been illustrated and described as AC type ventilation fans attached to the left and right of the first communication path 140 and the second communication path 150, respectively. It is also possible to change to a DC type ventilation fan that can selectively change the direction of airflow in both directions. In this case, it is sufficient to attach one DC type ventilation fan to each of the first communication passage 140 and the second communication passage 150.

従って、図６では、第２通風ファン１４３の代わりに第１連通通路１４０に取り付けられた第１ＤＣ通風ファンが、左側貯蔵室１１０からの冷気を強制的に右側貯蔵室１２０に流入させ、第４通風ファン１５３の代わりに第２連通通路１５０に取り付けられた第２ＤＣ通風ファンが、右側貯蔵室１２０からの冷気を強制的に左側貯蔵室１１０に流入させ、それによって左側貯蔵室１１０と右側貯蔵室１２０との間で冷気を循環させる。   Accordingly, in FIG. 6, the first DC ventilation fan attached to the first communication passage 140 instead of the second ventilation fan 143 forcibly causes the cool air from the left storage chamber 110 to flow into the right storage chamber 120, and A second DC ventilation fan attached to the second communication passage 150 instead of the ventilation fan 153 forces the cold air from the right storage chamber 120 to flow into the left storage chamber 110, thereby causing the left storage chamber 110 and the right storage chamber to flow. Cool air is circulated with 120.

一方、図７では、第１通風ファン１４２の代わりに第１連通通路１４０に取り付けられた第１ＤＣ通風ファンが、右側貯蔵室１２０からの冷気を強制的に左側貯蔵室１１０に流入させ、第３通風ファン１５２の代わりに第２連通通路１５０に取り付けられた第２ＤＣ通風ファンが、左側貯蔵室１１０からの冷気を強制的に右側貯蔵室１２０に流入させ、それによって左側貯蔵室１１０と右側貯蔵室１２０との間で冷気を循環させる。   On the other hand, in FIG. 7, instead of the first ventilation fan 142, the first DC ventilation fan attached to the first communication passage 140 forcibly causes the cold air from the right storage chamber 120 to flow into the left storage chamber 110, and A second DC ventilation fan attached to the second communication passage 150 instead of the ventilation fan 152 forcibly causes the cool air from the left storage chamber 110 to flow into the right storage chamber 120, thereby causing the left storage chamber 110 and the right storage chamber to flow. Cool air is circulated with 120.

その代わりに、通風ファンを取り付ける幾つかの方策があり得る。方策の１つは、連通通路の任意の１つ、例えば第１連通通路１４０に、通風ファンを取り付けることである。通風ファンは、ＤＣタイプのファンであり、気流の方向を選択的に両方向に変えるように制御される。   Instead, there can be several ways to install a ventilation fan. One of the measures is to attach a ventilation fan to any one of the communication passages, for example, the first communication passage 140. The ventilation fan is a DC type fan and is controlled so as to selectively change the direction of airflow in both directions.

別の方策は、１対のＡＣ通風ファンに代えて、それぞれの連通通路に１台ずつＡＣ通風ファンを取り付けることである。   Another measure is to install one AC ventilation fan in each communication passage instead of a pair of AC ventilation fans.

ここまで説明してきたように、本発明によるキムチ冷蔵庫に用いられる冷気循環装置には、左側貯蔵室及び右側貯蔵室を互いに連通されるようにすることができる第１及び第２連通通路と、第１及び第２連通通路を選択的に開閉できる第１及び第２ダンパとが設けられている。従って、左側貯蔵室内の温度が設定温度よりも高ければ、右側貯蔵室からの冷気が左側貯蔵室内に流入し、一方で、右側貯蔵室内の温度が設定温度よりも高ければ、左側貯蔵室からの冷気が右側貯蔵室に流入する。このようにして、各貯蔵室内の冷気が効果的に循環し、それによって冷気の温度を設定温度まで下げるための時間を短縮できる。   As described so far, the cold air circulation device used in the kimchi refrigerator according to the present invention includes the first and second communication passages that allow the left storage chamber and the right storage chamber to communicate with each other, First and second dampers that can selectively open and close the first and second communication passages are provided. Therefore, if the temperature in the left storage chamber is higher than the set temperature, cold air from the right storage chamber flows into the left storage chamber, while if the temperature in the right storage chamber is higher than the set temperature, Cold air flows into the right storage room. In this way, the cool air in each storage chamber is effectively circulated, thereby shortening the time for lowering the cool air temperature to the set temperature.

本発明について好適実施形態に関連して示しかつ説明してきたが、当業者であれば、下記の特許請求の範囲において画定される本発明の範囲を逸脱することなく、多様な変更及び修正がなされ得ることは理解されよう。   While the invention has been shown and described in connection with preferred embodiments, various changes and modifications can be made by those skilled in the art without departing from the scope of the invention as defined in the following claims. It will be understood that you get.
