Description
본 발명은 냉각장치의 냉기공급방법에 관한 것으로서, 상세하게는, 냉장고, 에어컨 기타 냉각장치에 외부 냉기공급장치로부터 냉기를 공급하는 방법에 관한 것이다.The present invention relates to a cold air supply method for a cooling device, and more particularly, to a method for supplying cold air from an external cold air supply device to a refrigerator, an air conditioner, or another cooling device.
일반적으로, 냉장고, 에어컨 등의 냉각장치는 내부에 자체 냉기공급장치를 가지고 있으며, 그 본체에 장착된 온도감지수단 및 제어부에 의해 냉각장치의 내부온도가 일정하도록 유지하는 구조를 취하고 있다.In general, a cooling device such as a refrigerator and an air conditioner has its own cold air supply device, and has a structure in which the internal temperature of the cooling device is kept constant by a temperature sensing means and a control unit mounted to the main body.
이하, 종래의 일반적인 냉각장치로서 내부 냉기공급장치에 의한 냉기공급방법을 취하는 경우를 설명하면 다음과 같다.Hereinafter, a case of taking a cold air supply method using an internal cold air supply device as a conventional general cooling device is as follows.
도 1은 종래의 냉각장치로서 냉장고의 구조를 도시한 단면도이다.1 is a cross-sectional view showing the structure of a refrigerator as a conventional cooling device.
도시된 바와 같이, 기본적으로 냉동실(1)과 냉장실(2)의 이중구조를 취하고 있고, 냉동실(1)의 후면에는 별도의 밀폐된 공간으로서 냉각기실(5)이 형성되어 있으며, 그 냉각기실(5)의 내부에는 증발기(6)를 비롯한 내부 냉기공급장치가 장착되어 있다.As shown in the drawing, the freezer compartment 1 and the refrigerating compartment 2 have a dual structure, and a cooler chamber 5 is formed on the rear side of the freezer compartment 1 as a separate enclosed space, and the cooler chamber ( 5) is equipped with an internal cold air supply device, including the evaporator (6).
상기 내부 냉기공급장치는 압축기, 응축기, 팽창밸브(미도시) 및 증발기(6)에 의해 구성되는 냉동사이클과 냉기를 순환시키기 위한 송풍팬(6)에 의해 이루어지며, 기타 냉장고 내부의 온도를 감지하기 위한 온도감지수단(8)과 상기 냉동사이클, 송풍팬(6)의 구동을 제어하는 제어부(미도시)에 의해 구성된다.The internal cold air supply device is formed by a refrigeration cycle composed of a compressor, a condenser, an expansion valve (not shown), and an evaporator 6, and a blowing fan 6 for circulating cold air, and senses the temperature inside the refrigerator. And a control unit (not shown) for controlling the driving of the temperature sensing means 8 and the refrigerating cycle and the blowing fan 6.
도어(3)의 개폐 등에 의해 냉동실(1) 또는 냉장실(2) 내부의 온도가 상승하면, 냉동실(1) 또는 냉장실(2) 내부에 장착된 온도감지수단(8)이 이를 감지하고, 제어부에 온도가 상승되었음을 알리는 신호를 전달한다.When the temperature inside the freezer compartment 1 or the refrigerating compartment 2 rises due to the opening and closing of the door 3, the temperature sensing means 8 mounted in the freezer compartment 1 or the refrigerating compartment 2 detects this, Delivers a signal that the temperature has risen.
제어부는 상기 압축기 또는 송풍팬(6)을 구동시켜 냉장고의 내부로서 온도가 상승된 부분에 냉기를 공급하여 적절한 온도를 유지할 수 있도록 한다.The control unit drives the compressor or the blower fan 6 to supply cold air to a portion where the temperature rises as the inside of the refrigerator to maintain an appropriate temperature.
상기에서는 냉장고의 예를 들었으나, 에어컨 기타 일정한 온도유지를 필요로 하는 냉각장치에 있어서, 내부 냉기공급장치에 의한 냉기공급방법은 상기와 대동소이하다고 할 수 있다.Although the example of the refrigerator has been described above, in the air conditioner or the like that requires a constant temperature maintenance, it can be said that the cold air supply method by the internal cold air supply device is similar to the above.
그런데, 이와 같은 내부 냉기공급장치에 의한 냉기공급방법은 그 냉기공급장치가 냉각장치의 내부에 장착되어야 한다는 한계가 존재하므로 냉기공급용량에도 제한이 가해지게 되고, 따라서 냉각장치 내부에 예상치 못한 과부하가 걸린 경우, 목표온도를 달성하지 못하게 되거나, 달성하더라도 많은 시간이 소요되어 냉각장치의 냉각목적에 이르지 못하는 상황이 발생할 수 있다는 문제점이 지적되어 왔다.However, since the cold air supply method by the internal cold air supply device has a limitation that the cold air supply device should be mounted inside the cooling device, the cold air supply capacity is also limited, thus unexpected overload inside the cooling device may occur. In the case of a problem, it has been pointed out that a situation in which the target temperature is not achieved or may take a long time even if the target temperature is not achieved does not reach the cooling purpose of the cooling device.
본 발명은 상기와 같은 문제점을 해결하여, 냉각장치 내부에 예상치 못한 과부하가 걸린 경우라 하더라도, 냉각장치 내부의 온도를 신속하고 효율적으로 목표온도에 도달할 수 있도록 하는 냉기공급방법을 제공하는 것을 그 목적으로 한다.The present invention is to provide a cold air supply method to solve the above problems, even if an unexpected overload inside the cooling device, the temperature inside the cooling device to reach the target temperature quickly and efficiently. The purpose.

도 2 및 도 3은 본 발명에 의한 냉기공급방법의 전제가 되는 냉각장치 및 냉기공급장치의 구조를 개략적으로 도시한 것으로서, 도 2는 하나의 냉각장치에 외부 냉기공급을 하는 경우를 도시한 구성도, 도 3은 복수개의 냉각장치에 외부 냉기공급을 하는 경우를 도시한 구성도이다.2 and 3 schematically show the structure of a cooling device and a cold air supply device that is a premise of the cold air supply method according to the present invention, Figure 2 is a configuration showing a case of supplying external cold air to one cooling device 3 is a block diagram showing a case where external cold air is supplied to a plurality of cooling devices.
도시된 바와 같이, 본 발명에 의한 냉각장치의 냉기공급방법은, 자체의 내부 냉기공급장치(210)를 구비한 냉각장치(200)와 별도의 외부 냉기공급장치(100) 사이를 냉기공급유로(310) 및 그 냉기공급유로의 개폐수단(320)에 의해 연결하는 단계와; 냉각장치(200) 내부의 적절한 온도를 설정하는 단계와; 냉각장치(200) 내부의 온도가 높아진 후, 상기 설정온도로 돌아가기까지 필요한 적절한 시간을 설정하는 단계와; 냉각장치(200)에 장착된 온도감지수단(220)에 의해 그 냉각장치(200) 내부의 온도를 감지하는 단계와; 상기 감지된 냉각장치(200) 내부의 온도가 상기 설정온도보다 높으면, 내부 냉기공급장치(210)를 구동하여 냉각장치(200)에 냉기를 공급하는 단계와; 내부 냉기공급장치(210)가 구동을 시작하고 상기 설정시간 내에 냉각장치(200) 내부의 온도가 상기 설정온도에 도달하지 못하면, 사용자가 상기 개폐수단(320)을 개방하여 냉기공급유로(310)를 통해 외부 냉기공급장치(100)로부터 냉각장치(200)로 냉기를 공급할 수 있도록, 냉기부족신호를 상기 외부 냉기공급장치에 장착된 표시부(110)를 통해 사용자에게 전달하는 단계를; 포함하여 구성된다.As shown, the cold air supply method of the cooling apparatus according to the present invention, between the cooling device 200 having its own internal air supply device 210 and the separate external air supply device 100 is a cold air supply passage ( 310 by the opening and closing means 320 of the cold air supply passage; Setting an appropriate temperature inside the cooling apparatus 200; Setting an appropriate time required to return to the set temperature after the temperature inside the cooling apparatus 200 becomes high; Sensing the temperature inside the cooling apparatus 200 by the temperature sensing means 220 mounted to the cooling apparatus 200; Supplying cold air to the cooling device 200 by driving an internal cold air supply device 210 when the sensed temperature inside the cooling device 200 is higher than the set temperature; When the internal cold air supply device 210 starts to drive and the temperature inside the cooling device 200 does not reach the set temperature within the set time, the user opens the opening and closing means 320 to supply the cold air supply flow path 310. Transmitting a cold shortage signal to a user through a display unit 110 mounted to the external cold air supply device to supply cold air from the external cold air supply device 100 to the cooling device 200 through the cold air supply device; It is configured to include.
즉, 냉각장치(200)의 내부에 장착된 온도감지수단(220)에 의해 내부온도를 감지하고, 그 내부온도가 설정온도보다 높으면 내부 냉기공급장치(210)를 구동하여 냉각장치(200)의 내부에 냉기를 공급한다는 점에서는 종래의 경우와 동일하다.That is, the internal temperature is sensed by the temperature sensing means 220 mounted inside the cooling device 200, and if the internal temperature is higher than the set temperature, the internal cold air supply device 210 is driven to operate the cooling device 200. It is the same as the conventional case in that cold air is supplied to the inside.
그러나, 내부 냉기공급장치(210) 만으로는 냉기의 공급이 부족하여 소정시간내에 냉각장치(200) 내부의 온도가 미리 설정된 목표온도에 도달하지 못하는 경우, 별도로 구성된 외부 냉기공급장치(100)에 의해 냉각장치(200)에 냉기를 공급한다는 점에서 종래의 경우와 근본적인 차이점을 갖는다.However, when the temperature of the inside of the cooling apparatus 200 does not reach a predetermined target temperature within a predetermined time due to insufficient supply of cold air by the internal cold air supply device 210 alone, cooling is performed by the external cold air supply device 100 configured separately. This is a fundamental difference from the conventional case in that the device 200 is supplied with cold air.
여기서, 외부 냉기공급장치(100)는 종래의 냉장고 등의 내부에 장착되는 냉기공급장치와 동일한 구조를 가지면 충분하며, 다만, 냉기공급유로(310)를 통해 냉각장치(200)의 내부에 냉기를 공급할 수 있는 구조를 취할 수 있으면 족하다.Here, the external cold air supply device 100 is sufficient to have the same structure as the cold air supply device mounted inside the conventional refrigerator, etc., except that the cold air inside the cooling device 200 through the cold air supply passage 310 It is enough if a structure can be supplied.
이와 같이 외부에서 냉기를 효율적으로 공급하기 위해서는 냉각장치(200) 내부에 냉기의 공급이 부족하다는 상황을 미리 인식하고 적기에 외부 냉기의 투입이 이루어질 수 있는 방법이 필요하다.As such, in order to efficiently supply cold air from the outside, a method for recognizing a situation in which the supply of cold air is insufficient in the cooling device 200 in advance and injecting external cold air in a timely manner is required.
본 발명에서는 냉각장치(200) 내부의 온도가 상승된 후, 목표온도로 돌아가는데 소요되는 시간을 미리 설정해 놓고, 그 설정시간 내에 냉각장치(200) 내부의 온도가 목표온도에 도달하는가를 기준으로 냉기공급의 부족 여부를 판단하도록 하였다.In the present invention, after the temperature inside the cooling apparatus 200 rises, the time required to return to the target temperature is set in advance, and the cold air is based on whether the temperature inside the cooling apparatus 200 reaches the target temperature within the set time. The shortage of supply was to be judged.
한편, 냉기공급의 부족이 판명된 경우, 외부 냉기공급장치(100)로부터 냉각장치(200)로 냉기를 공급하는 방식에는 수동식과 자동식의 2가지 경우를 강구해 볼 수 있다.On the other hand, when it is found that the lack of cold air supply, there are two cases of manual and automatic methods for supplying cold air from the external cold air supply device 100 to the cooling device 200.
수동식의 경우는, 냉각장치(200) 내부의 냉기공급 부족을 표시부(110)를 통해 사용자에게 인식되도록 하고, 사용자의 판단에 의거, 냉각장치(200)에의 외부 냉기공급 여부를 결정토록 하는 방식으로서, 냉각장치(200) 내부에 수납된 물품이 반드시 일정온도로서 저장될 필요성이 덜한 경우 절전 등의 차원에서 유리하다고 볼 수 있다.In the case of the manual type, as a way to allow the user to recognize the lack of cold air supply in the cooling device 200 through the display unit 110, and determine whether to supply the external cold air to the cooling device 200 on the basis of the user's judgment. In case the article stored in the cooling device 200 is not necessarily stored at a constant temperature, it may be advantageous in terms of power saving.
자동식의 경우는, 외부 냉기공급장치(100)의 일측에 설치되어, 온도감지수단 (220)으로부터 신호를 받아들여 개폐수단(320) 측으로 신호를 전달하는 제어부(미도시)를 마련하는 단계와; 내부 냉기공급장치(210)가 구동을 시작하고 상기 설정시간 내에 냉각장치(200)내부의 온도가 상기 설정온도에 도달하지 못하면, 상기 제어부가 상기 개폐수단(320)을 개방하여 냉기공급유로(310)를 통해 외부 냉기공급장치 (100)로부터 냉각장치(200)로 냉기를 공급하는 단계와; 상기 감지된 냉각장치(200) 내부의 온도가 상기 설정온도보다 낮으면, 상기 제어부가 상기 개폐수단(320)을 폐쇄하고 냉기공급장치(100)의 구동을 정지시키는 단계를; 포함하여 구성되는 것이 효과적이다.In the case of automatic, it is provided on one side of the external cold air supply device 100, providing a control unit (not shown) for receiving a signal from the temperature sensing means 220 and transmitting the signal to the opening and closing means 320 side; If the internal cold air supply device 210 starts to drive and the temperature inside the cooling device 200 does not reach the set temperature within the set time, the controller opens the opening and closing means 320 to supply the cold air supply flow path 310. Supplying cold air from the external cold air supply device 100 to the cooling device 200 through the; If the detected temperature inside the cooling device 200 is lower than the set temperature, the control unit closing the opening and closing means 320 and stopping the operation of the cold air supply device 100; It is effective to include.
이러한 방식은 냉각장치(200) 내부의 온도가 일정하게 유지될 필요성이 클 경우 안정적인 냉기공급을 이룰 수 있다는 점에서 효과적이다.This method is effective in that a stable cold air supply can be achieved when the temperature inside the cooling device 200 needs to be kept constant.
