본 발명은 냉장고에 관한 것으로, 더욱 상세하게는 냉장고 고내의 온도를 다양한 온도범위로 조절하는 냉장고의 온도제어장치에 관한 것이다.The present invention relates to a refrigerator, and more particularly, to a temperature control apparatus of a refrigerator for controlling a temperature in a refrigerator refrigerator in various temperature ranges.

이하 종래 기술에 따른 냉장고의 온도절환장치에 대해 살펴보면 다음과 같다.Looking at the temperature switching device of the refrigerator according to the prior art as follows.

도 1은 종래 기술에 따른 냉장고이다.1 is a refrigerator according to the prior art.

종래기술인 미국 공개공보 USP6,343,477를 살펴보면 다음과 같다.Looking at the prior art US Patent Publication USP6,343,477 as follows.

종래 기술은 도면에 도시되고 있는 바와 같이 밀폐된 하우징 내부에 온도센서, 댐퍼 및 송풍팬 등이 구성된다. 종래에는 냉동실로부터 토출된 냉기는 냉기덕트를 통해서 도면에 도시되고 있는 고내에 공급된다. 이때, 고내에 냉기가 신속하게 공급될 수 있도록 댐퍼가 열리고, 송풍팬이 구동한다. 이와 같이 고내에 공급되는 냉기의 흐름을 제어하는 댐퍼와 송풍팬으로 구성된 냉기량조절부(178)가 구비된다.In the prior art, a temperature sensor, a damper, a blowing fan, and the like are configured in a sealed housing as shown in the drawing. Conventionally, the cold air discharged from the freezing chamber is supplied to the inside of the refrigerator shown in the drawing through the cold air duct. At this time, the damper is opened so that cold air can be supplied quickly into the refrigerator, and the blower fan is driven. As described above, a cool air amount adjusting unit 178 including a damper and a blowing fan for controlling the flow of cold air supplied into the refrigerator is provided.

또한, 냉장고의 운전 모드 및 고내온도를 세팅하기 위한 신호입력부(58a)가 냉장실 내부에 구성된다. 따라서 사용자가 운전모드 및 고내 온도를 설정하기 위해서는 도어를 열고 수행하여야만 한다.In addition, a signal input unit 58a for setting the operation mode and the high internal temperature of the refrigerator is configured inside the refrigerator compartment. Therefore, the user must open the door to set the operation mode and the internal temperature.

이상 살펴본 종래 기술(미국 공개공보 USP6,343,477)은, 일반적인 간접냉각방식으로서, 냉장실 고내의 온도를 조절하기 위해서 냉동실로부터 토출된 냉기를 냉장실 고내에 공급받는다.The above-described prior art (US Published US Pat. No. 6,343,477) is a general indirect cooling method, in which cold air discharged from a freezer compartment is supplied into a cold compartment to control a temperature in the refrigerator compartment.

따라서 종래에는, 냉동실에 있는 냉기를 특정실로 송풍해야 하므로, 냉동실로부터 냉장실로 연결되는 덕트와 댐퍼/송풍팬이 필요하였다. 이러한 구성때문에, 냉동실로부터 냉장실로 냉기의 이동에 따른 덕트 내부 및 댐퍼 등에 결빙 등이 발생하여, 댐퍼 등의 동작성에 문제점이 있었다.Therefore, in the related art, since the cold air in the freezing chamber must be blown to a specific chamber, a duct and a damper / blowing fan connected from the freezing chamber to the refrigerating chamber were required. Due to such a configuration, freezing of the inside of the duct, the damper, and the like caused by the movement of the cold air from the freezing chamber to the refrigerating chamber occurs, and there is a problem in the operability of the damper.

그리고 종래 냉장고는 신호입력부가 냉장실 내부에 있어서, 동작신호를 입력하고자 하는 경우 도어를 개방해야하므로 고내의 냉기가 누설되어, 소비전력이 증가하는 문제점이 있었다.In addition, the conventional refrigerator has a problem in that the signal input unit is inside the refrigerating chamber, and when the user wants to input an operation signal, the door needs to be opened so that cold air in the refrigerator leaks and power consumption increases.

따라서 본 발명의 목적은 냉기 누설없이 효율적으로 고내 온도의 조절이 가능한 냉장고의 온도제어장치를 제공함에 있다. Accordingly, an object of the present invention is to provide a temperature control apparatus of a refrigerator capable of efficiently controlling the internal temperature of the refrigerator without leakage of cold air.

상기 목적을 달성하기 위한 본 발명에 따른 냉장고의 온도제어장치는, 냉장실, 냉동실 및 절환실 등 다수개의 고내를 구성하는 냉장고에 있어서, 냉매를 압축하는 압축기와; 냉매를 응축하는 응축기와; 응축기를 통해서 공급받은 냉매를 이용해 냉장실 열교환작업을 수행하는 냉장실 증발기와; 응축기를 통해서 공급받은 냉매를 이용해 절환실 열교환작업을 수행하는 절환실 증발기와; 상기 응축기의 냉매가 상기 냉장실 증발기와 절환실 증발기로 공급되도록 냉매유로를 개폐제어하는 3방향밸브와; 상기 절환실 내부에 구성되어, 절환실 내부를 가열하는 히터와; 상기 냉장실 증발기와 절환실 증발기를 통과한 냉매를 이용해, 냉동실 열교환작업을 수행하는 냉동실 증발기를 포함하여 구성된다.According to an aspect of the present invention, there is provided a temperature control apparatus for a refrigerator, the refrigerator including: a refrigerator, a freezing chamber, and a switching chamber, the refrigerator comprising: a compressor for compressing a refrigerant; A condenser condensing the refrigerant; A refrigerator compartment evaporator for performing a refrigerator compartment heat exchange operation using the refrigerant supplied through the condenser; A switching room evaporator configured to perform a switching room heat exchange operation using the refrigerant supplied through the condenser; A three-way valve for opening and closing the refrigerant passage so that the refrigerant of the condenser is supplied to the refrigerating chamber evaporator and the switching chamber evaporator; A heater configured inside the switching room to heat the inside of the switching room; It is configured to include a freezer compartment evaporator for performing a freezer compartment heat exchange operation, using the refrigerant passing through the refrigerating compartment evaporator and the switching room evaporator.

그리고 상기 목적을 달성하기 위한 본 발명에 따른 냉장고의 온도제어장치는, 상기 절환실의 보관적정온도를 높게 세팅하면, 절환실에 향한 3방향밸브의 냉매유로가 폐쇄함과 동시에, 히터가 구동하여 고내온도를 상승시키는 것을 특징으로 한다.And the temperature control device of the refrigerator according to the present invention for achieving the above object, when the storage proper temperature of the switching room is set high, the refrigerant flow path of the three-way valve toward the switching room is closed, the heater is driven It is characterized by raising the internal temperature.

그리고 본 발명에 따른 냉장고의 온도제어장치에서, 상기 절환실의 고내 온도는, 절환실 내부에 구성된 온도센서에 의해서 감지되는 것을 특징으로 한다.And in the temperature control apparatus of the refrigerator according to the present invention, the internal temperature of the switching room is characterized by being sensed by a temperature sensor configured in the switching room.

이하 본 발명에 따른 냉장고의 온도제어장치에 대해 상세하게 살펴보면 다음과 같다.Hereinafter, the temperature control device of the refrigerator according to the present invention will be described in detail.

도 2는 본 발명에 따른 냉장고의 사시도이다.2 is a perspective view of a refrigerator according to the present invention.

도면에 도시되고 있는 바와 같이, 냉장실(110) 및 냉동실(120)로 이루어진 다수개의 고내가 구성되고, 냉장실(110)의 상부에 가변온도실로서 절환실(100)이 별도로 마련되어 있다. 상기 절환실(100)은, 주위가 단열벽체로 폐쇄되어져 있다. 그리고 상기 절환실(100) 내부는 절환실의 고내를 가열하는 히터와 절환실 고내온도를 감지하는 온도센서가 별도로 구성되어져 있다.As shown in the figure, a plurality of chambers consisting of the refrigerating chamber 110 and the freezing chamber 120 are configured, and the switching chamber 100 is separately provided as a variable temperature chamber on the upper side of the refrigerating chamber 110. In the said switching room 100, the periphery is closed by the heat insulation wall. In addition, the inside of the switching room 100 has a heater for heating the inside of the switching room and a temperature sensor for detecting the temperature inside the switching room.

그리고 냉장실 외부에는 컨트롤패널(도시하지 않음)이 구성되어, 운전모드 및 온도 등을 세팅한다.A control panel (not shown) is configured outside the refrigerating compartment to set the operation mode and temperature.

따라서 사용자가 상기 컨트롤패널을 통해서 세팅한 운전모드 및 온도 조건에 따라서, 냉장실(110), 냉동실(120) 및 절환실(100)의 온도대역이 설정된다. 이때, 상기 절환실(100)은 내부에 구성된 절환실 증발기와 히터의 구성으로 보관온도대역을 광범위하게 조절할 수 있는 특징을 가진다.Therefore, the temperature ranges of the refrigerating chamber 110, the freezing chamber 120, and the switching chamber 100 are set according to the operation mode and the temperature conditions set by the user through the control panel. At this time, the switching room 100 has a feature that can be controlled in a wide range of storage temperature band by the configuration of the switching room evaporator and heater configured therein.

즉, 사용자가 절환실을 낮은 온도로 세팅한 경우, 압축기 및 응축기를 통과한 냉매가 3방향밸브의 제어에 의해서 절환실 내부에 공급되어, 열교환작업을 수행함으로서, 고내온도를 낮은 온도대역으로 제어하는 것이 가능해진다.That is, when the user sets the switching chamber to a low temperature, the refrigerant passing through the compressor and the condenser is supplied to the inside of the switching chamber by the control of the three-way valve, and the heat exchange operation is performed to control the high temperature inside the low temperature band. It becomes possible.

한편, 사용자가 절환실을 상기 경우보다 상대적으로 높은 온도로 세팅한 경우, 절환실 고내에 냉기가 공급되지 않도록 3방향밸브는 절환실 증발기에 공급되는 냉매유로를 폐쇄한다. 그리고 절환실 내부에 있는 히터가 가열동작을 수행함으로서, 절환실의 고내온도를 상승시킨다. 이에 따라 사용자가 설정한 온도를 유지할 수 있다.On the other hand, when the user sets the switching chamber to a relatively higher temperature than the above case, the three-way valve closes the refrigerant passage supplied to the switching chamber evaporator so that cold air is not supplied to the switching chamber. Then, the heater inside the switching room performs the heating operation, thereby raising the internal temperature of the switching room. Accordingly, the temperature set by the user can be maintained.

도 2에 도시되고 있는 바와 같이 본 발명의 냉장고는, 도어를 통해서 외부의 실내공기와 일차적으로 차단되고, 2차적으로 냉장실, 절환실, 냉동실 고내에 구성된 분리칸(일예로 서랍식)으로 인해서 실내공기를 차단하고 있다. 이에 따라 보다 신선한 보관이 가능해진다.As shown in FIG. 2, the refrigerator of the present invention is primarily blocked from the outside indoor air through a door, and the indoor air is secondary due to a separation compartment (for example, a drawer type) configured in a refrigerating compartment, a switching compartment, and a freezer compartment. Is blocking. This allows for fresher storage.

도 3은 본 발명에 따른 냉장고의 고내 온도를 제어하기 위한 냉각사이클도이다.3 is a cooling cycle diagram for controlling the internal temperature of the refrigerator of the present invention.

도면에 도시되고 있는 바와 같이 본 발명은 고내온도를 제어하기 위해서, 다음과 같은 냉각사이클을 구비한다.As shown in the figure, the present invention includes the following cooling cycle in order to control the internal temperature of the refrigerator.

본 발명의 냉각사이클을 위한 제어구성은, 냉매를 압축하는 압축기(200)와, 냉매를 응축하는 응축기(210)와, 냉장실 증발기(230) 또는 절환실 증발기(240)로 냉매가 유입되도록 조정하는 3방향밸브(220)와, 냉장실에 열교환작업을 수행하기 위해서 냉매를 증발하는 냉장실 증발기(230)와, 절환실 열교환작업을 수행하기 위해서 냉매를 증발하는 절환실 증발기(240)와, 냉동실 열교환작업을 수행하기 위해서 냉매를 증발하는 냉동실 증발기(270)를 포함하여 구성되고 있다.The control configuration for the cooling cycle of the present invention, the compressor 200 for compressing the refrigerant, the condenser 210 for condensing the refrigerant, and adjusts the refrigerant to be introduced into the refrigerating chamber evaporator 230 or the switching room evaporator 240. Three-way valve 220, the refrigerating chamber evaporator 230 for evaporating the refrigerant to perform the heat exchange operation in the refrigerating chamber, the switching chamber evaporator 240 for evaporating the refrigerant to perform the switching room heat exchange operation, the freezer compartment heat exchange operation It comprises a freezer compartment evaporator 270 for evaporating the refrigerant to perform the.

상기 3방향밸브(220)가 컨트롤패널(도시하지 않음)로부터 입력된 운전모드 및 온도 등에 따라, 냉매유로의 개폐여부를 조정하는 과정은, 마이크로컨트롤러(도시하지 않음)의 제어에 의해서 이루어진다.The three-way valve 220 adjusts the opening and closing of the refrigerant passage according to an operation mode and a temperature input from a control panel (not shown), and is controlled by a microcontroller (not shown).

상기 냉각사이클의 흐름을 살펴보면 우선, 압축기(200)를 통해서 냉매가 압축되고, 압축된 냉매는 응축기(210)에 전달된다. 응축기(210)를 통과한 냉매의 흐름은 3방향밸브(220)를 통해서 냉장실 증발기(230) 또는 절환실 증발기(240)로 조정된다.Looking at the flow of the cooling cycle, first, the refrigerant is compressed through the compressor 200, the compressed refrigerant is delivered to the condenser 210. The flow of the refrigerant passing through the condenser 210 is adjusted to the refrigerating chamber evaporator 230 or the switching chamber evaporator 240 through the three-way valve 220.

3방향밸브(220)가 냉장실 증발기(230)로 유로를 형성하게 되면, 상기 냉장실 증발기(230)에 냉매가 공급된다. 이에 따라 냉장실 증발기(230)는 열교환작업을 수행하고, 냉장실 팬(도시하지 않음)의 동작으로 냉장실에 냉기가 공급된다.When the three-way valve 220 forms a flow path to the refrigerating chamber evaporator 230, the refrigerant is supplied to the refrigerating chamber evaporator 230. Accordingly, the refrigerating chamber evaporator 230 performs a heat exchange operation, and the cold air is supplied to the refrigerating chamber by the operation of the refrigerating chamber fan (not shown).

그러나 3방향밸브(220)가 절환실 증발기(240)로 유로를 형성하게 되면, 상기 절환실 증발기(240)에 냉매가 공급된다. 이에 따라 절환실 증발기(240)는 열교환작업을 수행하고, 절환실 팬(도시하지 않음)의 동작으로 절환실에 냉기가 공급된다.However, when the three-way valve 220 forms a flow path to the switching room evaporator 240, the refrigerant is supplied to the switching room evaporator 240. Accordingly, the switching room evaporator 240 performs a heat exchange operation, and cold air is supplied to the switching room by the operation of the switching room fan (not shown).

그리고 상기 냉장실 증발기(230)와 절환실 증발기(240)로 유입된 냉매는, 냉동실 증발기(270)로 유입된다. 상기 냉동실 증발기(270)는 열교환작업을 수행하고, 냉동실 팬(도시하지 않음)의 동작으로 냉동실에 냉기가 공급된다.The refrigerant introduced into the refrigerating chamber evaporator 230 and the switching chamber evaporator 240 flows into the freezing chamber evaporator 270. The freezer compartment evaporator 270 performs a heat exchange operation, and cold air is supplied to the freezer compartment by an operation of a freezer compartment fan (not shown).

상기 냉동실 증발기(270)를 통과한 냉매는 다시 압축기(200)로 유입되어, 냉매를 압축하여 응축기(210)로 전달함으로서, 상기와 같은 냉각사이클을 반복수행하게 된다.The refrigerant passing through the freezer compartment evaporator 270 again flows into the compressor 200, compresses the refrigerant, and delivers the refrigerant to the condenser 210, thereby repeatedly performing the cooling cycle as described above.

또한, 상기 3방향밸브의 동작으로 냉장실 및 절환실 모두 유로가 형성되면, 상기 냉장실 증발기와 절환실 증발기 측으로 냉매가 유입되고, 열교환작업을 수행한다. 이로서, 동시에 냉장실 및 절환실 내에 냉기가 공급될 수 있다.In addition, when a flow path is formed in both the refrigerating chamber and the switching chamber by the operation of the three-way valve, the refrigerant flows into the refrigerating chamber evaporator and the switching chamber evaporator, and performs a heat exchange operation. As a result, cold air can be supplied to the refrigerating chamber and the switching chamber at the same time.

이와 같이 냉각사이클을 수행함에 있어서, 냉장실 및 냉동실의 고내온도제어는 종래와 동일하게 이루어진다. 즉, 냉장실 및 냉동실의 고내적정온도가 유지될 수 있도록, 냉장실 및 냉동실 고내에 구성된 온도센서를 통해서 감지된 온도값을 기초로 하여, 냉장실 및 냉동실 증발기에 냉매가 공급되어 열교환작업을 수행한다.In performing the cooling cycle as described above, the internal temperature control of the refrigerating compartment and the freezing compartment is performed as in the prior art. That is, the refrigerant is supplied to the refrigerating compartment and the freezing compartment evaporator based on the temperature values sensed by the temperature sensors configured in the refrigerating compartment and the freezing compartment chamber so that the high temperature inside the refrigerating compartment and the freezing compartment is maintained.

한편, 상기 절환실의 고내온도는 다양하게 세팅 및 제어가 가능하다. 즉, 냉장고의 외부에 장착된 컨트롤패널(도시하지 않음)로부터 절환실 저온모드를 선택하면, 마이크로컨트롤러(도시하지 않음)는 3방향밸브(220)가 절환실 증발기(240)측으로 열리도록 제어한다. On the other hand, the internal temperature of the switching room can be variously set and controlled. That is, when the switching room low temperature mode is selected from a control panel (not shown) mounted outside the refrigerator, the microcontroller (not shown) controls the three-way valve 220 to be opened to the switching room evaporator 240. .

그 결과 압축기(200) 및 응축기(210)를 통과한 냉매는 절환실 증발기(240)에 공급되고, 절환실 증발기(240)에서 열교환작업을 수행함으로서, 절환실 고내에 차가운 공기를 공급하는 것이 가능해진다.As a result, the refrigerant passing through the compressor 200 and the condenser 210 is supplied to the switching chamber evaporator 240, and by performing a heat exchange operation in the switching chamber evaporator 240, it is possible to supply cool air in the switching chamber. Become.

그러나 냉장고의 외부에 장착된 컨트롤패널(도시하지 않음)로부터 절환실 고온모드를 선택하면, 마이크로컨트롤러(도시하지 않음)는 3방향밸브(220)가 냉장실 증발기(230)측으로 열리도록 제어한다. 그리고 절환실 증발기(240)측으로 열려있던 냉매유로가 폐쇄된다. 이에 따라 압축기(200) 및 응축기(210)를 통과한 냉매는 냉장실 증발기(240)에 공급된다.However, when the switching room high temperature mode is selected from a control panel (not shown) mounted to the outside of the refrigerator, the microcontroller (not shown) controls the three-way valve 220 to open to the refrigerating compartment evaporator 230. And the refrigerant flow path which was opened to the switch room evaporator 240 side is closed. Accordingly, the refrigerant passing through the compressor 200 and the condenser 210 is supplied to the refrigerator compartment evaporator 240.

절환실(100)의 온도를 상승시킬 필요가 있을 때, 절환실 내부에 구성된 히터(250)를 통해서 절환실의 온도를 상승시킨다. 즉, 절환실 내부에 구성된 히터(250)가 발열동작을 수행하고, 상기 히터(250)의 가열에 의해서 절환실 내부의 온도가 상승하게 된다. 상기 히터(250)의 동작은 마이크로컨트롤러와 온도센서(260)의 감지온도값을 근거로 하여 동작제어된다. When it is necessary to raise the temperature of the switching room 100, the temperature of the switching room is raised through the heater 250 comprised in the switching room. That is, the heater 250 configured in the switching chamber performs the heating operation, and the temperature inside the switching chamber is increased by the heating of the heater 250. The operation of the heater 250 is operation controlled based on the detected temperature value of the microcontroller and the temperature sensor 260.

따라서 온도센서(260)를 통해서 측정된 온도값이 사용자가 세팅한 절환실 고온모드에 해당되는 고내온도인 경우, 히터(250)의 발열을 정지시킨다. 그리고 다시 온도센서(260)를 통해서 측정된 온도값이 사용자가 세팅한 절환실 고온모드에 벗어나면, 히터(250)의 고내가열을 재동작시킨다.Therefore, when the temperature value measured by the temperature sensor 260 is the internal temperature corresponding to the switching room high temperature mode set by the user, the heating of the heater 250 is stopped. When the temperature value measured by the temperature sensor 260 is out of the switching room high temperature mode set by the user, the internal heating of the heater 250 is restarted.

이와 같이 본 발명은 냉장실 및 냉동실의 고내온도제어를 통해서 보관물의 보관은 물론이거니와, 기존의 냉장 및 냉동실의 보관온도보다 높은 보관온도를 필요로 하는 저장물의 보관도 가능해진다. 또한 본 발명은 냉장실 및 절환실의 사용여부에 따라 3방향밸브의 냉매유로를 제어함에 따라서, 3방향밸브의 유로제어를 통해 사용하지 않는 고내에 불필요하게 냉매가 공급되는 것을 방지할 수 있다.Thus, the present invention, as well as the storage of the storage through the high temperature control of the refrigerating chamber and the freezer compartment, it is also possible to store the storage that requires a storage temperature higher than the storage temperature of the existing refrigerator and freezer compartment. In addition, according to the present invention, by controlling the refrigerant flow path of the three-way valve in accordance with the use of the refrigerating chamber and the switching room, it is possible to prevent the refrigerant from being unnecessarily supplied to the unused chamber through the flow control of the three-way valve.

그 결과 지역별, 계절별 , 특성상 다를 수 있는 저장물의 보관온도를 적정하게 유지/보관하는 것이 가능해진다.As a result, it is possible to properly maintain / storage storage temperatures that may vary by region, season and nature.
