상기 냉동실(210)에는 한 개의 선반(214)이, 냉장실(220)에는 수개의 선반(224)이 설치되어 있다.One shelf 214 is provided in the freezer compartment 210, and several shelves 224 are installed in the refrigerating compartment 220.
또한, 상기 냉동실(210)에는 냉동실온도 감지센서(215)가, 냉장실(220)에는 냉장실온도 감지센서(225)가 구비되어 있으며, 냉장실(220)의 전면판넬에는 도어개폐 감지센서(226)가 구비되어 있다.In addition, the freezer compartment 210 has a freezer compartment temperature sensor 215, the refrigerator compartment 220 is provided with a refrigerator compartment temperature sensor 225, the front panel of the refrigerator compartment 220 is a door opening and closing sensor 226 is It is provided.
그리고 본 발명 실시례에서는 냉장실 증발기(222)에서 열교환된 냉기가 토출되는 유로와, 흡입되는 유로가 구분되도록 리어 커버(228)와 프론트 커버(229)가 연결되어 있고, 상기 토출유로와 연결되어 냉장실의 상측에서 냉기를 하향분사시키는 냉기토출덕트(240)가 상기 특선실(227)의 하면에 설치되어 있는 것이 특징이다.In the embodiment of the present invention, the rear cover 228 and the front cover 229 are connected to separate the flow path through which the cold air heat-exchanged in the refrigerating chamber evaporator 222 is discharged and the suction path, and are connected to the discharge flow path to connect the refrigerating chamber. The cold air discharge duct 240 for spraying the cold air downward from the upper side is characterized in that it is provided on the lower surface of the special chamber (227).
상기 냉기토출덕트(240)에는 덕트의 후단부에 냉기를 좌우측으로 분산시키는 수개의 에어가이드(241)가 설치되어 있고, 냉기토출덕트(240)의 유로가 선단부로 갈수록 넓어지도록 양측에 스페이서덕트(242)가 설치되며, 이 스페이서덕트(242)의 내측면은 코안다(Coanda)(242a)면으로 형성되어 있다.The cold air discharge duct 240 is provided with a plurality of air guides 241 for dispersing cold air to the left and right sides at the rear end of the duct, and the spacer duct (on both sides so that the flow path of the cold air discharge duct 240 becomes wider toward the tip end). 242 is provided, and the inner surface of the spacer duct 242 is formed of a Coanda 242a surface.
이러한 코안다면(242a)에 의해 벽면을 따라 냉기가 흐르도록 하는 코안다 효과(Coanda effect)를 발생시키도록 한다.The co-facial surface 242a causes the Coanda effect to cause cold air to flow along the wall surface.
즉, 이와 같이 스페이서덕트(242)를 코안다면(242a)으로 형성함으로써 도 5a에서 보는 바와 같이, 에어가이드(241)에 의해 좌우측으로 분산되어 안내되는 냉기가 코안다면(242a)을 따라 흐르면서 냉기토출덕트(240)의 선단부에서 균일하게 토출되도록 구성한 것이다.That is, by forming the spacer duct 242 as the co-face 242a as described above, as shown in FIG. 5A, the cold air dispersed and guided left and right by the air guide 241 flows along the co-face if 242a. It is configured to be evenly discharged from the front end of the duct 240.
스페이서덕트(242')에 코안다면이 형성되지 않고, 직선으로 된 면(242'a)은 경우에는 도 5b에서와 같이 냉기토출유로상의 좌우측단부에서 냉기가 토출되지 않게 되어 냉장실의 전면부에 에어커튼을 형성하지 못하게 된다.No co-facial surface is formed in the spacer duct 242 ', and the straight surface 242'a does not discharge cold air from the left and right ends of the cold air discharge passage as shown in FIG. 5B. It will not form a curtain.
미설명 부호 216, 217은 냉동실의 리어커버 및 프론트 커버이고, 229a, 229b는 냉동실의 냉기토출공 및 냉기흡입공이다.Reference numerals 216 and 217 denote rear covers and front covers of the freezer compartment, and 229a and 229b denote cold air discharge holes and cold air suction holes of the freezer compartment.
이와 같이 구성되어 있는 본 발명 실시례에 의한 냉장고의 냉기 순환 장치의 동작을 도 6 내지 도8을 참조하여 설명한다.The operation of the cold air circulation system of the refrigerator according to the embodiment of the present invention configured as described above will be described with reference to FIGS. 6 to 8.
냉장고에 전원이 인가되면, 냉동실온도 감지센서(215)에서 냉동실의 온도를 감지하여 이러한 검출값을 제어부로 보내면, 제어부는 냉동실(210)의 온도가 설정온도보다 큰 경우에 압축기(230)와, 냉동실의 송풍팬(213)을 작동시킨다.When power is supplied to the refrigerator, the freezer compartment temperature sensor 215 senses the temperature of the freezer compartment and sends this detection value to the controller, where the controller controls the compressor 230 when the temperature of the freezer compartment 210 is greater than the set temperature. The blower fan 213 of the freezer compartment is operated.
냉동실의 온도가 설정온도보다 작으면 제어부는 압축기(230)와 냉동실 송풍팬(213)을 정지시킨다.If the temperature of the freezer compartment is lower than the set temperature, the control unit stops the compressor 230 and the freezer compartment blower fan 213.
그 다음에 냉장실(220)에서는 냉장실온도 감지센서(225)에서 감지된 냉장실(220) 내부의 온도에 의하여 냉장실의 온도가 설정온도보다 큰 상태이면 제어부가 냉장실 팬(223)을 구동시키고, 냉장실의 설정온도보다 작은 상태이면 냉장실 팬(223)을 정지시킨다.Next, in the refrigerating chamber 220, if the temperature of the refrigerating chamber is greater than the set temperature by the temperature inside the refrigerating chamber 220 detected by the refrigerating chamber temperature sensor 225, the control unit drives the refrigerating chamber fan 223, If the temperature is lower than the set temperature, the refrigerator compartment fan 223 is stopped.
이와 같이 냉장실 팬(223)의 구동을 냉장실(220) 내부의 온도에 따라 구동시키는 동작은 종래 기술과 동일하지만, 본 발명에서는 냉장실(220) 내부의 온도가 설정온도보다 낮더라도 냉장실 도어(221)가 개방된 상태에서는 계속해서 냉장실 팬(223)을 구동시키도록 하고 있다.As described above, the operation of driving the refrigerating compartment fan 223 according to the temperature inside the refrigerating chamber 220 is the same as in the related art. However, in the present invention, even if the temperature inside the refrigerating chamber 220 is lower than the set temperature, the refrigerating compartment door 221 In the open state, the refrigerating chamber fan 223 is continuously driven.
즉, 냉장실의 도어(221)가 닫힌 상태에서 냉장실(220) 내부의 온도가 설정온도보다 높은 경우에는 당연히 냉장실 팬(223)을 구동시킴으로써 도 6에서 보는 바와 같이, 냉기토출공(229b)으로 토출된 냉기는 특선실(227)로 공급되고, 냉기토출덕트(240)를 통해 토출된 냉기는 냉장실(220)의 상측으로 균일하게 분산되어 하강됨으로써 각 선반(224)의 공간에서 순환된 후, 냉기흡입공(229b)을 통해 증발기(222)로 귀환된다.That is, when the temperature inside the refrigerating chamber 220 is higher than the set temperature in the state in which the refrigerating chamber door 221 is closed, it is naturally discharged to the cold air discharge hole 229b by driving the refrigerating chamber fan 223 as shown in FIG. 6. The cold air is supplied to the specialty chamber 227, and the cold air discharged through the cold air discharge duct 240 is uniformly dispersed and lowered to the upper side of the refrigerating chamber 220, thereby being circulated in the space of each shelf 224, and then the cold air. It is returned to the evaporator 222 through the suction hole 229b.
또한, 냉장실 도어(221)가 개방된 상태라도 제어부는 냉장실 내부의 온도 크기에 관계없이 무조건 냉장실 팬(223)을 작동시켜 도 7에서 보는 바와 같이, 특선실(227)과 냉기토출덕트(240)를 통해 냉기가 토출되며, 특히 냉기토출덕트(240)로 토출되는 냉기는 냉기토출덕트의 에어가이드(241)와, 코안다면(242a)의 효과에 의하여 냉기토출덕트(240)의 선단부에서 균일하게 분산된 상태로 하강됨으로써 냉장실(220)의 전면에서 에어 커튼(air curtain)(250)이 형성되어 냉장실 도어(221)가 열린 상태에서도 냉장실(220)의 내부 냉기가 외부로 누출되지 않게 되는 것이다.In addition, even when the refrigerating compartment door 221 is open, the control unit operates the refrigerating compartment fan 223 unconditionally regardless of the temperature inside the refrigerating compartment, as shown in FIG. 7, the special selection chamber 227 and the cold air discharge duct 240. The cold air is discharged through the air, and in particular, the cold air discharged to the cold air discharge duct 240 is uniformly at the distal end of the cold air discharge duct 240 due to the air guide 241 of the cold air discharge duct and the co-face 242a. The air curtain 250 is formed on the front surface of the refrigerating compartment 220 by being lowered in a dispersed state so that the internal cold air of the refrigerating compartment 220 does not leak to the outside even when the refrigerating compartment door 221 is opened.
도 9는 본 발명 실시례에 의한 동작을 나타낸 플로우 차트이다.9 is a flowchart illustrating the operation according to the embodiment of the present invention.
한편, 도 10은 별도의 에어커튼 선택스위치를 구비한 경우의 냉기 순환 방법을 보인 플로우 챠트로서, 이러한 냉기 순환 방법에 의하면 냉장실 도어(221)가 개방된 상태에서, 사용자의 의사에 따라 선택적으로 냉장실 팬(223)을 구동시키거나, 정지시킬 수 있다.On the other hand, Figure 10 is a flow chart showing a cold air circulation method when a separate air curtain selection switch is provided, according to the cold air circulation method, the refrigerator compartment door 221 in the open state, selectively in accordance with the user's intention The fan 223 may be driven or stopped.
본 발명은 증발기에서 토출되는 냉기의 토출경로를 냉장실의 상부측에서 균일하게 분산시켜 하강되도록 구성함으로써 냉장실 도어가 개방된 상태에서도 냉장실의 전면부에 에어 커튼이 형성되어 고내의 냉기가 외부로 빠져나가는 것을 방지하는 효과가 있다.The present invention is configured such that the discharge path of the cold air discharged from the evaporator is uniformly distributed on the upper side of the refrigerating compartment to descend, so that an air curtain is formed on the front side of the refrigerating compartment even when the refrigerating compartment door is opened, so that the cold air in the refrigerator escapes to the outside. It is effective to prevent that.
또한, 냉장실의 도어가 개방된 상태에서는 고내의 온도의 크기에 관계없이 냉장실 팬을 구동시켜 냉기의 순환을 원활하게 하도록 하는 효과도 있다.In addition, in the state in which the door of the refrigerating chamber is opened, there is also an effect to smooth the circulation of cold air by driving the refrigerating chamber fan regardless of the size of the temperature in the refrigerator.
이와 같이 본 발명은 하나의 냉장실 팬을 사용하여 에어커튼이 형성되는 효과를 거둘 수 있어 제조원가를 절감할 수 있고, 팬의 무리한 구동으로 인해 발생되는 소음을 저감시키는 효과가 있다.As described above, the present invention can achieve the effect that the air curtain is formed by using one refrigerator compartment fan, thereby reducing manufacturing costs and reducing noise generated by excessive driving of the fan.
