본 고안은 물을 외부에서 음용가능케 하는 디스팬서(DISPENSER)가 장착된 냉장고에 관한 것으로, 특히 디스팬서용 물통에 직접 냉기를 공급할 수 있는 별개의 덕트를 설치함과 아울러 온도감지수단과 냉기단속용 개폐수단을 추가 개재하여 측정된 온도에 따라 개폐수단을 단속함으로써 물통에 공급되는 냉기를 적절히 제어되도록 한 디스팬서가 장착된 냉장고의 물통온도 제어장치에 관한 것이다.The present invention relates to a refrigerator equipped with a dispenser (dispenser) for drinking water from the outside, in particular for the installation of a separate duct that can supply cold air directly to the dispenser bucket for temperature sensing means and cold control The present invention relates to a bucket temperature control apparatus of a refrigerator equipped with a dispenser equipped with an opening / closing means to control the cool air supplied to the bucket by controlling the opening / closing means according to the measured temperature.

종래의 디스팬서가 장착된 냉장고는 제1도에 도시된 바와 같이 냉동실(F)과 냉장실(R)로 분리되며, 상기 냉장실(R)의 상측으로 육명실(5)이 구비되되, 이 육명실(5) 윈도우(51)에 근접되는 도어(6)에 물통(4)이 설치된다.A refrigerator equipped with a conventional dispenser is divided into a freezer compartment (F) and a refrigerator compartment (R), as shown in FIG. 1, and a sixth chamber (5) is provided above the refrigerator compartment (R). (5) The water bottle 4 is installed in the door 6 which adjoins the window 51. As shown in FIG.

그리고, 상기 냉동실(F)의 후방으로 냉동사이클장치를 구성하는 증발기(2)가 설치되며, 또한 냉장실(R) 하부의 후방으로 냉매가스를 고온고압으로 압축하는 압축기(7)가 설치되는 한편, 상기 증발기(2)의 직 상부에 냉각용 팬(1)이 설치된다.In addition, an evaporator 2 constituting the refrigerating cycle apparatus is installed to the rear of the freezing chamber F, and a compressor 7 for compressing the refrigerant gas at a high temperature and high pressure to the rear of the lower part of the refrigerating chamber R is installed. A cooling fan 1 is installed directly above the evaporator 2.

이와 같이 구성된 종래 냉장고의 냉기 순환과정은 압축기(2)의 가동으로 인해 냉매가스가 고온고압으로 압축된 후 응축기(미도시)와 팽창밸브(미도시)를 거쳐 증발하기 좋은 상태로 변한 다음 증발기(2) 쪽으로 순환된다. 이때 증발기(2)의 상부에 설치된 냉각용 팬(1)에 의해 덕트(a)를 통해 냉동실(F) 및 냉장실(R)로 냉기가 급송되고, 이 급속된 냉기로 저장식품을 냉동 및 냉장한다.In the cold air circulation process of the conventional refrigerator configured as described above, after the refrigerant gas is compressed to high temperature and high pressure due to the operation of the compressor 2, the refrigerant gas is changed to a good state to evaporate through a condenser (not shown) and an expansion valve (not shown), and then the evaporator ( Circulated to 2). At this time, the cold air is fed to the freezing compartment F and the refrigerating compartment R through the duct a by the cooling fan 1 installed at the upper part of the evaporator 2, and the stored food is frozen and refrigerated by the rapid cold. .

한편, 냉각용 팬(1)에 의해 급송된 냉기의 일부분은 냉기토출구(b)를 통해 육명실(5)로 공급되고, 육명실(5)에 설치된 윈도우(51)를 거쳐 디스팬서용 물통(4)으로 냉기가 공급됨에 따라 음용자는 상시 냉각된 물을 공급받을 수 있게 된다.Meanwhile, a part of the cold air supplied by the cooling fan 1 is supplied to the sixth chamber 5 through the cold air discharge port b, and the dispenser bucket through the window 51 installed in the sixth chamber 5 ( As the cold air is supplied to 4), the drinker can receive the water cooled at all times.

그런데 상술한 종래 기술은 물통(4)으로 급송되는 냉기가 육명실(5) 윈도우(51)의 방해로 인해 손실이 발생되므로써 물통의 냉각성능을 크게 저하시키는 주원인이 되었다.By the way, the above-described prior art has become a major cause of the reduction in the cooling performance of the bucket by the loss caused by the interruption of the cooling chamber 5, the window 51, the cold air fed to the bucket (4).

따라서 본 고안은 상술한 물통의 냉각성능을 해결하기 위하여 창출한 것으로서, 그, 목적은 냉각용 팬에 의해 급송된 냉기가 직접 물통으로 공급하도록 별개의 덕트를 설치한 상태에서 냉기 단속용 개폐수단 및 온도감지수단을 설치하여 물통의 온도를 신속하고 정확하게 제어하며, 또 다른 장애물없는 독립적인 냉각이 이루어지도록 한 냉장고를 제공함에 있다.Therefore, the present invention was created in order to solve the cooling performance of the above-described bucket, the purpose of which is the opening and closing means for controlling the cold air in a state in which a separate duct is installed so that the cold air fed by the cooling fan is directly supplied to the bucket. By providing a temperature sensing means to control the temperature of the water tank quickly and accurately, and to provide a refrigerator to achieve independent cooling without another obstacle.

상기 목적을 달성하기 위한 본 고안은 냉장고의 덕트 일측에 디스팬서용 덕트를 설치하되 물통까지 연장 형성한 것에 있어서, 상기 디스팬서용 덕트의 적소에 설치되며, 전기신호의 구동으로 냉기를 단속케 하는 개폐수단과, 물통의 온도를 감지하는 온도감지수단과, 상기 온도감지수단에서 감지된 온도데이터를 근거로 냉기단속 출력신호로 상기 개폐수단을 제어하는 마이컴이 구비된 특징이 있다.The present invention for achieving the above object is to install a dispenser duct on one side of the duct of the refrigerator, but extends to the bucket, is installed in place of the dispenser duct, to control the cold air by driving the electric signal The opening and closing means, a temperature sensing means for sensing the temperature of the water tank, and a microcomputer for controlling the opening and closing means with a cold air output signal based on the temperature data detected by the temperature sensing means.

이하, 첨부된 도면에 의거하여 본 고안의 바람직한 일 실시예를 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 고안은 종래 기술에서 언급된 부품을 그대로 수용함에 따라 이에 대한 세세한 설명을 동일부호로써 설명한다.The present invention will be described with the same reference numerals as detailed description thereof as it accepts the parts mentioned in the prior art.

제2도에 있어서, 본 고안은 냉장고의 덕트(a) 적소에 디스팬서용 덕트(b)를 설치하여 냉각용 팬(1)에 의해 급송된 냉기가 물통(4)까지 직접 공급되도록 설치한다. 그리고, 상기 덕트(4)의 상측으로 냉기를 단속하는 솔레노이드밸브(121)를 구비하며, 또 물통(4)에 근접되는 부위에 온도센서인 써미스터(TH)를 추가 개재한다.In FIG. 2, the present invention installs the dispenser duct (b) in place of the duct (a) of the refrigerator so that the cold air fed by the cooling fan (1) is directly supplied to the bucket (4). A solenoid valve 121 for controlling cold air is provided above the duct 4, and a thermistor TH, which is a temperature sensor, is further interposed between the solenoid valve 121 and a portion close to the water tank 4.

이와같이 설치한 상태에서 제3도와 같이 접속하여 구성하는 바, 즉 디스팬서용 덕트(b)의 적소에 물통(4)으로 공급되는 냉기를 후술하는 마이컴(10)의 전기적인 제어신호에 의해 단속하는 개폐수단(12)과, 물통(4)의 온도를 감지하여 마이컴(10)에 입력하는 온도감지수단(11)과, 상기 온도감지수단(11)에서 감지된 온도데이터를 입력받아 이를 근거로 출력단에 접속된 개폐수단(12)을 적절히 단속하는 마이컴(10)이 접소된 구성이다.In this state of installation, the connection is made as shown in FIG. 3, that is, the intermittent control is performed by the electric control signal of the microcomputer 10 which will be described later. Opening and closing means 12, the temperature sensing means 11 for sensing the temperature of the water bottle 4 and input to the microcomputer 10, and the output stage based on the received temperature data sensed by the temperature sensing means 11 The microcomputer 10 which appropriately interrupts the opening-closing means 12 connected to this is connected.

그리고, 제4도는 제3도의 일실시예를 보인 상세회로도로서, (12)는 개폐수단으로, 상기 마이컴(10)의 출력신호를 반전하는 인버터(I1)와, 이 인버터(I1)에 의해 반전된 신호로 솔레노이드밸브(121)에 인가되는 전원(AC)을 단속하는 릴레이(RY)로 구성된다.4 is a detailed circuit diagram showing an embodiment of FIG. 3, in which 12 is an opening / closing means, an inverter I1 for inverting the output signal of the microcomputer 10 and an inverted by the inverter I1. It consists of a relay (RY) for intermitting the power (AC) applied to the solenoid valve 121 with the signal.

(11)은 온도감지수단으로, 써미스터(TII) 및 저항(R1-R2)으로 구성되어 물통의 변화된 온도를 전압변화에 의해 검출한다.Reference numeral 11 denotes a temperature sensing means, which is composed of thermistor TII and resistors R1-R2 to detect the changed temperature of the water tank by the voltage change.

(10)은 마이컴으로, 전압에 의해 동작하여 냉장고의 전체동작을 총괄제어함과 아울러 본 고안의 입력단(PI1), 출력단(PO1)으로 물통의 온도를 제어한다.Numeral 10 is a microcomputer, which operates by a voltage to collectively control the overall operation of the refrigerator, and controls the temperature of the water tank by the input terminal PI1 and the output terminal PO1 of the present invention.

상술한 바와 같이 구성된 본 고안은 먼저 전원공급에 의해 동작이 시작되며, 이후 압축기(7) 및 냉각용 팬(1)을 구동하여 순환통로상의 공기가 증발기(2)를 거치면서 열교환되어 냉기로 변한 다음 덕트(a)를 통해 냉동실(F) 및 냉장실(R)로 냉기가 강제공급되면서 식품을 냉동 및 냉장하는 통상의 작업을 실시한다.The present invention configured as described above is first started by the power supply, and then driven by the compressor (7) and the cooling fan (1) the air in the circulation passage is heat exchanged through the evaporator (2) is changed to cold Next, while the cold air is forced to the freezing compartment F and the refrigerating compartment R through the duct a, a normal operation of freezing and refrigerating food is performed.

동시에, 덕트(a) 적소에 설치된 디스팬서용 덕트(b)를 통해 냉기가 물통(4)으로 직접 공급됨에 의해 물통(4) 역시 신속하게 냉각된다.At the same time, the water tank 4 is also rapidly cooled by supplying cold air directly to the water tank 4 through the dispenser duct b installed in place of the duct a.

이때의 동작제어는 초기상태가 물통(4)의 온도가 높은 상태 즉 물통의 온도를 감지하는 써미스터(TII) 및 저항(R1-R2)의 변화된 전압(Vcc)이 마이컴(10)의 입력단(PI1)으로 입력되고, 마이컴(10)은 입력단(PI1)을 통해 검출된 온도가 소정의 온도이하로 판별되면 출력단(PO1)에 접속된 개폐수단(12)에 로우레벨신호를 보낸다.At this time, the operation control is performed in the initial state where the temperature of the bucket 4 is high, that is, the voltage Vcc of the thermistor TII and the resistors R1-R2 that sense the temperature of the bucket is input terminal PI1 of the microcomputer 10. ) And the microcomputer 10 sends a low level signal to the opening / closing means 12 connected to the output terminal PO1 when the temperature detected by the input terminal PI1 is determined to be equal to or less than a predetermined temperature.

상기 로우레벨신호는 인버터(I1)를 통해 반전되며, 이 반전된 신호로 릴레이(RY)의 코일을 비자화시켜 스위치를 오프시킴으로써 결국 전원(AC)이 솔레노이드밸브(121)에 인가되지 않게 된다.The low level signal is inverted through the inverter I1. The inverted signal causes the coil of the relay RY to be non-magnetic to switch off so that power AC is not applied to the solenoid valve 121.

따라서 솔레노이드밸브(121)의 오프동작으로 인해 물통(4)에 직접 공급되는 냉기가 계속적으로 강하게 공급되므로써 물통(4)의 설정온도이상까지 냉기의 공급이 이루어진다.Therefore, since the cold air supplied directly to the water tank 4 is continuously supplied due to the off operation of the solenoid valve 121, the cold air is supplied to a temperature higher than the set temperature of the water tank 4.

그리하여 물통(4)의 냉각이 이루어지면서 물통(4)의 온도를 감지하는 써미스터(TII) 및 저항(R1-R2)의 변화된 전압이 마이컴(10)의 입력단(PI1)으로 입력되고, 마이컴(10)은 입력단(PI1)을 통해 검출된 온도가 소정의 온도 이상으로 판별되면 출력단(PO1)에 접속된 개폐수단(12)에 하이레벨신호를 보낸다.Thus, the cooling of the water tank 4 is performed, and the changed voltages of the thermistor TII and the resistors R1-R2 for sensing the temperature of the water tank 4 are input to the input terminal PI1 of the microcomputer 10, and the microcomputer 10 ) Transmits a high level signal to the opening / closing means 12 connected to the output terminal PO1 when the temperature detected through the input terminal PI1 is determined to be equal to or higher than a predetermined temperature.

상기 하이레벨신호는 인버터(I1)를 통해 반전되며, 이 반전된 신호로 릴레이(RY)의 코일을 자화시켜 스위치를 온시킴으로써 결국 전원(AC)이 솔레노이드밸브(121)에 인가된다.The high level signal is inverted through the inverter I1. The inverted signal magnetizes the coil of the relay RY to turn on the switch, so that power AC is applied to the solenoid valve 121.

이어, 솔레노이드밸브(121)의 온동작으로 인해 물통(4)에 직접 공급되는 냉기를 차단함으로써 설정온도 이상까지 냉기의 공급을 억제한다.Subsequently, the cold air supplied directly to the water tank 4 is blocked by the ON operation of the solenoid valve 121 to suppress the supply of cold air to a set temperature or more.

이상에서 살펴본 바와 같이 본 고안은 냉각용 팬에 의해 급송된 냉기가 직접 물통으로 공급됨에 의해 물통의 냉각을 신속하게 하는 이점이 있음과 함께 적절한 제어수단의 확보로 인해 정확한 온도제어도 가능한 여러 가지 이점이 있다.As described above, the present invention has the advantage that the cooling of the water tank is quickened by supplying the cold air fed by the cooling fan directly to the water tank, and also various advantages that enable accurate temperature control by securing appropriate control means. There is this.

이상의 설명은 본 고안의 일실시예에 불과하며, 본 고안의 그 구성요지 범위내에서 얼마든지 변경이 가능하다.The above description is only one embodiment of the present invention, and can be changed as many within the scope of the present invention.
