본 발명은 냉장실 겸용 에어컨에 관한 것으로서, 더 상세하게는 에어컨의 기능뿐만 아니라 냉장실의 기능을 갖춘 냉장실 겸용 에어컨에 관한 것이다.The present invention relates to a refrigerating air conditioner, and more particularly, to a refrigerating air conditioner having a function of a refrigerating compartment as well as a function of an air conditioner.

종래 기술에 따른 냉장실 겸용 에어컨을 도면을 참조하여 살펴보면 다음과 같다. 도 1은 하나의 종래 기술에 따른 냉장실 겸용 에어컨에 대한 장치의 개략도이다.Looking at the refrigeration room combined air conditioner according to the prior art with reference to the drawings as follows. 1 is a schematic diagram of an apparatus for a combined refrigerating air conditioner according to one prior art.

에어컨 본체(1)의 내부에 설치되어있는 홴(2)이 작동하게 되면 이로 인하여 흡입구(6)를 통해 외부에서 공기가 흡입되어 냉각판(3)으로 유입하면서 공기가 냉각된다. 냉각된 공기는 홴(2)의 흡입력에 의하여 전면에 설치되어 있는 송풍구(7)를 통하여 실내로 유입하게 된다. 이때, 차단판(4)에 의하여 냉기가 음료보관부(5)로 유입하게 되므로 음료를 냉각할 수 있다.When the fan 2 installed inside the air conditioner main body 1 is operated, air is sucked from the outside through the inlet 6 and flows into the cooling plate 3 while cooling the air. Cooled air is introduced into the room through the air inlet 7 installed at the front side by the suction force of the fan (2). At this time, since the cold air flows into the beverage storage part 5 by the blocking plate 4, the beverage can be cooled.

그러나 이러한 종래 기술은 에어컨에 의해 실내로 공급되는 공기의 온도(약 18℃)에 의해 음료보관부(5)가 냉각되기 때문에 일반적인 냉장고 냉장실에 보관된 음료보다 시원하지 않아 사용자의 기대수준을 만족시키지 못하는 문제점이 있다.However, since the beverage storage unit 5 is cooled by the temperature of the air supplied to the room by the air conditioner (about 18 ° C.), the conventional technology is not cooler than the beverage stored in the general refrigerator refrigerating chamber and does not satisfy the user's expectations. There is a problem.

도 2는 다른 종래 기술에 따른 냉장실 겸용 에어컨의 또 다른 예이다.Figure 2 is another example of another refrigeration room combined air conditioner according to the prior art.

실내로 유입되는 공기와 냉장실용 공기의 증발온도를 다르게 설정하기 위한 2개의 증발기(6),(7)와 각 증발기에 연결되는 2개의 팽창밸브(8),(9) 및 공기를 송풍하기 위한 홴(2)을 포함하여 냉장실(5)에 냉각 공기를 공급하는 구조로 이루어져 있다.Two evaporators (6) and (7) for setting different evaporation temperatures of the air flowing into the room and air for the refrigerating chamber, two expansion valves (8) and (9) connected to each evaporator, and for blowing air It consists of a structure which supplies cooling air to the refrigerating chamber 5 including the fin (2).

그러나 이러한 경우 냉매의 분기와 합류가 일어나고 부하 조건에 따라 냉장실용 증발기(7)와 에어컨용 증발기(6)의 냉매 유량을 적절히 안배하여야 하므로 제어가 쉽지 않은 문제점이 있다.However, in this case, branching and confluence of the coolant occur, and the flow rate of the coolant in the refrigerating chamber evaporator 7 and the air conditioner evaporator 6 is appropriately arranged according to the load conditions, which makes it difficult to control.

따라서 본 발명은 1개의 증발기와 1개의 팽창 밸브만을 사용해서 구조가 간단하며, 냉매 제어가 용이하면서도, 또한 냉장실 요구 온도 조건과 에어컨 공기 요구 온도 조건을 모두 만족시킬 수 있는 냉장실 겸용 에어컨을 제공함에 있다. Accordingly, the present invention is to provide a refrigeration room air conditioner using a single evaporator and one expansion valve is simple in structure, easy to control the refrigerant, and also satisfies both the refrigerating room temperature requirements and the air conditioning air temperature requirements. .

이하 본 발명에 따른 냉장실 겸용 에어컨에 대해 살펴보면 다음과 같다. Looking at the refrigeration room combined air conditioner according to the present invention as follows.

도 3은 본 발명에 따른 냉장실 겸용 에어컨에 대한 개략도이다. 3 is a schematic diagram of a refrigerating unit air conditioner according to the present invention.

본 발명에 따른 냉장실 겸용 에어컨은 도면에 도시되어 있는 바와 같이, 냉매가 증발하기 쉽도록 교축 작용을 하여 냉장에 필요한 최적 온도조건(약 5℃)을 제공하는 팽창밸브(600); 상기 팽창밸브(600)에 연결되어 있으며 냉장실(R)의 부하변동에 큰 영향을 받지 않고 안정적으로 냉장실(R)을 냉각시키는 냉각블록(100); 에어컨 본체 하단에 있는 흡입구(800)로 공기가 유입되어 증발기(200)를 통과하도록 공기를 순환하는 제 1 송풍기(300); 실내 공간으로 최적온도의 공기를 제공하기 위해 증발기(200)를 통과한 저온의 공기와 상온의 공기를 혼합하여 배출시키는 작용을 하는 제 2 송풍기(500); 및 에어컨 상부 흡입구로 유입되는 공기량을 조절하여 항상 최적의 설정 공기온도를 조성할 수 있도록 개도가 조절되는 개폐식 흡입구(400)를 포함하여 구성되고 있다. 이때, 냉각블록(100)은 통상 널리 쓰이는 축열효과가 크며 열전도성이 좋은 공지의 금속으로 된 블록이면 되나, 이에 한정되지는 않는다.
한편, 상기 증발기(200)를 통과한 공기가 상기 개폐식 흡입구(400)로 유입된 공기와의 혼합 없이 곧바로 제2송풍기(500)로 가지 않도록 상기 증발기(200)를 통과한 공기의 유로를 안내하는 한편, 제 1 송풍기(300)와 제 2 송풍기(500) 주변 공간을 분리하도록 하는 격벽(1000)이 상기 제 1 송풍기와 제 2 송풍기 사이에 구비된다.Refrigerator combined air conditioner according to the present invention, as shown in the drawings, the expansion valve 600 that provides the optimum temperature conditions (about 5 ℃) required for refrigeration by the refrigerant acts to easily evaporate; A cooling block (100) connected to the expansion valve (600) and stably cooling the refrigerating chamber (R) without being greatly influenced by the load variation of the refrigerating chamber (R); A first blower 300 which circulates air so that air is introduced into the inlet 800 at the bottom of the air conditioner main body and passes through the evaporator 200; A second blower 500 which serves to mix and discharge low-temperature air and room-temperature air that have passed through the evaporator 200 to provide an air of optimum temperature to the indoor space; And it is configured to include a retractable intake opening 400 is adjusted to open the air so as to adjust the amount of air flowing into the upper air intake inlet to always create the optimal set air temperature. In this case, the cooling block 100 may be a block made of a known metal having a large heat storage effect and a good thermal conductivity, which is generally used, but is not limited thereto.
On the other hand, to guide the flow path of the air passed through the evaporator 200 so that the air passing through the evaporator 200 does not go directly to the second blower 500 without mixing with the air introduced into the opening and closing inlet (400). On the other hand, the partition wall 1000 for separating the space around the first blower 300 and the second blower 500 is provided between the first blower and the second blower.

본 발명의 팽창밸브(600)는 통상적으로 에어컨에 사용되는 팽창밸브와는 달리 냉장실(R)에 저온을 제공할 수 있을 정도로 감압시킴으로써 냉장실(R)을 5℃ 정도로 유지한다.The expansion valve 600 of the present invention maintains the refrigerator compartment R at about 5 ° C. by reducing the pressure enough to provide a low temperature to the refrigerator compartment R, unlike the expansion valve normally used for air conditioners.

이로 인해 증발기(200)를 통과한 공기의 온도 또한 5℃ 정도가 되므로 이렇게 냉각된 공기가 직접 실내로 유입되면 너무 저온이라 불쾌감을 유발함과 동시에 건강에 좋지 않다. 따라서, 예컨대 통상적인 에어컨이 공급하는 공기 온도 18℃가 되도록 하기 위해 본 발명에서는 에어컨 본체 상부 후방에 있는 개폐식 흡입구(400)로부터 실온의 공기(20℃ 이상)를 유입하여 증발기를 통과한 차가운 공기(5℃ 정도)와 혼합하여 18℃ 정도의 공기로 만들어서 송풍구(1100)를 통해 배출시킨다.As a result, the temperature of the air passing through the evaporator 200 is also about 5 ° C., when the cooled air is directly introduced into the room, it is so low that it causes discomfort and is not good for health. Therefore, in order to achieve an air temperature of 18 ° C. supplied by a conventional air conditioner, for example, cold air (20 ° C. or more) is introduced into the room temperature air (20 ° C. or more) from the open / close inlet 400 located at the rear of the air conditioner body. 5 ° C.) and mixed into air of about 18 ° C. and discharged through the tuyeres 1100.

이를 위해 개폐식 흡입구(400)를 통해 유입되는 공기량을 조절할 수 있어야하며 이러한 공기량 조절은 개폐식 흡입구(400)의 개도를 변화시킴과 동시에 제 2 송풍기(500)의 회전수를 조절함으로써 가능하다. 즉, 적정 에어컨 공기온도를 제공하기 위해 에어컨에서 실내로 배출되기 직전의 공기 온도를 센서(900)로 감지하여 설정온도보다 높으면 제 2 송풍기의 회전수를 조절함과 더불어 개폐식 흡입구(400)의 개도를 닫아 흡입공기량을 적게 하고 설정온도보다 낮으면 개도를 열어 흡입공기량을 많게 함으로서 항상 최적온도(약 18℃)의 공기를 실내에 공급할 수 있도록 한다.To this end, it should be possible to adjust the amount of air introduced through the retractable inlet 400 and this air amount control is possible by changing the opening degree of the retractable inlet 400 and at the same time adjust the number of revolutions of the second blower (500). That is, in order to provide an appropriate air conditioner air temperature, the air temperature immediately before being discharged from the air conditioner to the room is sensed by the sensor 900, and when the temperature is higher than the set temperature, the number of rotations of the second blower is adjusted and the opening degree of the open / close inlet 400 is adjusted. Close the air inlet to reduce the amount of intake air and lower than the set temperature.
