일반적으로 차량에는 냉,난방 장치가 있으나, 식품(음식물)을 냉장, 보온할 수 있는 냉,온장고는 없으며, 대형 차량 즉 버스 또는 특장차의 경우 냉방장치를 이용한 냉장고를 구비한 것이 있고, 최근들어 고급 승용차에도 냉장고를 구비한 것이 있다.In general, there are cooling and heating devices in vehicles, but there are no cooling and heating cabinets to cool and insulate food (food). In the case of a large vehicle, such as a bus or a special vehicle, there is a refrigerator using an air conditioning system. Some cars are equipped with a refrigerator.

그러나 상기 대형 차량이나 승용차에 구비된 냉장고는 차량의 냉방장치를 이용하기 때문에, 상기 식품을 냉장하고자 할 경우 차량의 냉방장치를 가동시키지 않으면 식품을 냉장할 수 없을 뿐만 아니라, 상기 냉장고는 냉장 기능만을 가지고 있어, 식품(음식물)을 보온하고자 할 경우에는 전혀 보온할 수 없게 된다.However, since the refrigerator provided in the large vehicle or the passenger car uses the cooling device of the vehicle, when the refrigerator is to be refrigerated, the refrigerator cannot be refrigerated unless the cooling device of the vehicle is operated. If you want to keep food (food), you can not keep at all.

이와 같이 종래에는 대형 차량에 냉,온장고가 없거나 혹은 냉방장치를 이용한 냉장고 만을 구비하고 있어, 냉장 식품이 아닌 보온을 요하는 식품의 경우에는 보온을 하지 못하거나 혹은 별도의 보온 장치를 구비하여 보온을 하여야 하는 번거로움이 있고, 상기 식품 냉장시에는 차량의 냉방장치를 작동시켜야 하므로 냉방장치 작동에 따른 연료 소비는 물론 구동 소음을 야기시키는 문제점을 가지고 있었다.As such, conventionally, a large vehicle does not have a refrigerator, a refrigerator, or a refrigerator using an air conditioner, and thus, foods that require heat rather than refrigerated food cannot be kept warm or have a separate heat storage device to keep warm. There is a hassle to be done, and when the food refrigeration has to operate the cooling device of the vehicle had a problem of causing fuel noise as well as driving noise due to the cooling device operation.

따라서 본 발명의 목적은 대형 차량인 트럭이나 버스내에 냉난방 장치와는 별도로 열전소자의 전류 흐름 방향에 따라 흡열과 방열 작용으로 냉각 및 가열할 수 있는 보관함을 구비함으로써, 간단하면서 편리하게 식품을 냉장, 보온할 수 있도록 하는 냉,온장고를 제공하고자 하는데 있다.Accordingly, an object of the present invention is to provide food storage equipment simply and conveniently by providing a storage box capable of cooling and heating by heat absorption and heat dissipation according to the current flow direction of the thermoelectric element in a truck or bus, which is a large vehicle.

이하 본 발명의 바람직한 실시예를 첨부되는 도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, described in detail with reference to the accompanying drawings, preferred embodiments of the present invention.

도 1은 본 발명 대형 차량의 냉,온장고의 요부 확대 절결 종단면도 이고, 도 2는 본 발명 대형 차량용 냉,온장고의 제어 블럭도로서, 임의로 설정된 소정의 크기를 갖는 보관함(10)의 외측벽 일측에는 전류의 흐름에 따라 흡열 및 방열하는 열전소자(11)와; 상기 열전소자(11)에 전원단(12)으로 부터 인가되는 전류 흐름 제어 및 입,출력 신호를 제어하는 제어수단(13)과; 상기 제어수단(13)에 의하여 외기를 흡입 및 방열하는 팬모터(14)와; 상기 제어수단(13)에 의하여 보관함(10)의 내부 온도를 감지하는 온도 센서(15)로 구성한다1 is an enlarged vertical cross-sectional view of the main portion of the cold vehicle, the refrigerator of the present invention, Figure 2 is a control block diagram of the refrigerator, the refrigerator for the present invention, one side of the outer wall of the storage box 10 having a predetermined size arbitrarily set A thermoelectric element 11 which absorbs and dissipates as current flows; Control means (13) for controlling the current flow control and input and output signals applied from the power supply terminal (12) to the thermoelectric element (11); A fan motor 14 which sucks and radiates outside air by the control means; It consists of a temperature sensor 15 for sensing the internal temperature of the storage box 10 by the control means (13).

상기 열전소자(11)는 전기 전도가 양호한 두종류의 다른 금속판(A)(B)과, 상기 다른 금속판(A)(B)사이에 정공에 의하여 전기를 전도하는 P형 반도체(P)와, 전자에 의하여 전기를 전도하는 N 형 반도체(N)를 각각 접합 형성한다.The thermoelectric element 11 is a P-type semiconductor (P) for conducting electricity by holes between the two different metal plate (A) (B) and the other metal plate (A) (B) having good electrical conduction, The N-type semiconductors N, which conduct electricity by electrons, are respectively formed by bonding.

상기와 같이 구성되는 본 발명은 대형 차량의 운전석 일측에 설치하고. 시거짹이나 혹은 차량 밧데리와 연결하게 된다.The present invention configured as described above is installed on one side of the driver's seat of a large vehicle. It may be connected to a cigar or battery.

이와 같이 전원을 연결한 상태에서 운전자는 보관함(10)에 식품(과일, 음료수 혹은 도시락)을 넣고 냉장 혹은 보온을 할 수 있게 된다.In this state, the driver can put food (fruit, drink or lunch box) into the storage box 10 and refrigerated or keep warm.

이때 보관함(10)의 냉장, 보온은 제어수단(13)을 통해서 전원단(12)을 제어하여 보관함(10)의 외주벽 일측에 장착된 열전소자(11)에 전원을 인가하게 되면,열전소자(11)는 인가되는 전원의 전류 흐름 방향에 따라 금속판(A)(B)과 P 형 반도체(P)와 N 형 반도체(N)간의 접합 부위에서 발생되는 주울열을 흡수하거나, 방열 작용으로 금속판(A)(B)을 가열하고 냉각하는 과정으로 이루어진다.At this time, the refrigeration and thermal insulation of the storage box 10 controls the power stage 12 through the control means 13, when the power is applied to the thermoelectric element 11 mounted on one side of the outer peripheral wall of the storage box 10, the thermoelectric element (11) absorbs Joule heat generated at the junction between the metal plate (A) (B) and the P-type semiconductor (P) and the N-type semiconductor (N) according to the current flow direction of the applied power, or the metal plate by the heat radiation action (A) (B) is heated and cooled.

따라서 상기 보관함(10)에 넣어진 식품중 냉장 식품인 경우, 운전자는 제어수단(13)을 조작하여 전원단(12)으로 부터 전류의 흐름을 열전소자(11)의 금속판(B)을 통해서 N 형 반도체(N)에서 P 형 반도체(P)방향으로 인가하게 되면, 상기 N 형 반도체(N)의 전자는 금속판(A)에서 금속판(B)으로 흐르게 되고, 상기 P 형 반도체(P)의 정공 역시 금속판(A)에서 금속판(B)으로 흐르게 되므로 상기 금속판(A)의 접합부에서 발생되는 열을 흡수하여 금속판(B)로 방열하게 되어 상기 금속판(A)의 접합부 온도가 하강하여 냉각이 이루어지고 된다.Therefore, in the case of the refrigerated food of the food put into the storage box 10, the driver operates the control means 13 to flow the current from the power supply terminal 12 through the metal plate (B) of the thermoelectric element (11) N When applied in the P-type semiconductor P direction from the type semiconductor (N), electrons of the N-type semiconductor (N) flows from the metal plate (A) to the metal plate (B), the hole of the P-type semiconductor (P) Also flows from the metal plate (A) to the metal plate (B) to absorb the heat generated from the junction of the metal plate (A) to radiate heat to the metal plate (B), the temperature of the junction of the metal plate (A) is lowered and the cooling is made do.

그러므로 상기 보관함(10)의 외측벽이 냉각되어 보관함(10)의 내부 온도를 하강시켜 냉장 식품을 냉장시키게 되는 것이다.Therefore, the outer wall of the storage box 10 is cooled to cool the refrigerated food by lowering the internal temperature of the storage box 10.

이때 보관함(10)의 냉장 온도는 온도 센서(15)를 통해서 감지하면서 냉장시키게 되고, 상기 보관함(10)의 냉장 효율은 팬모터(14)를 구동시켜 상기 금속판(A)으로 부터 열을 흡수하여 금속판(B)으로 신속하게 방열시켜 줌으로써 냉각 및 냉장 효율을 향상할 수 있게 된다.At this time, the refrigerating temperature of the storage box 10 is detected by the temperature sensor 15 to be refrigerated, and the storage efficiency of the storage box 10 drives the fan motor 14 to absorb heat from the metal plate A. By rapidly dissipating the metal plate (B) it is possible to improve the cooling and refrigeration efficiency.

한편 상기 보관함(10)으로 음식물을 보온하고자 할 경우, 운전자는 상기 냉장 시와 달리, 상기 제어수단(13)을 조작하여 전원단(12)으로 부터 전류의 흐름을 열전소자(11)의 금속판(B)을 통해서 P 형 반도체(P)에서 N 형 반도체(N)방향으로 인가하게 되면, 상기 P형 반도체(P)의 정공은 금속판(B)에서 금속판(A)으로 흐르게되고, 상기 N 형 반도체(N)의 전자 역시 금속판(B)에서 금속판(A)으로 흐르게 되므로 상기 금속판(B)의 접합부에서 발생되는 열을 흡수하여 금속판(A)로 방열하게 되어 상기 금속판(A)의 접합부 온도는 상승이 이루어지고 된다.On the other hand, if you want to keep the food in the storage box 10, unlike the refrigeration, the driver operates the control means 13 to flow the current from the power source 12 to the metal plate of the thermoelectric element 11 ( When the P-type semiconductor P is applied in the N-type semiconductor N direction through B), holes of the P-type semiconductor P flow from the metal plate B to the metal plate A, and the N-type semiconductor Since the electrons of (N) also flow from the metal plate B to the metal plate A, the heat generated at the junction of the metal plate B is absorbed and radiated to the metal plate A so that the junction temperature of the metal plate A increases. This is done.

그러므로 상기 보관함(10)의 외측벽은 금속판(A)의 온도 상승으로 가열되어 보관함(10)의 내부 온도를 상승시켜 주게 되므로, 보온 식품을 보온시키게 되는 것이다.Therefore, the outer wall of the storage box 10 is heated by the temperature rise of the metal plate (A) to increase the internal temperature of the storage box 10, thereby keeping warm food.

이때 보관함(10)의 상승 온도는 온도 센서(15)를 통해서 감지하면서 보온시키게 되고, 상기 보관함(10)의 보온 효율은 팬모터(14)를 구동시켜 상기 금속판(B)으로 부터 흡수된 열이 금속판(A)으로 신속하게 방열시켜 줌으로써 향상시킬 수 있게 된다.At this time, the rising temperature of the storage box 10 is sensed by the temperature sensor 15 to keep warm, and the thermal insulation efficiency of the storage box 10 drives the fan motor 14 to absorb the heat absorbed from the metal plate (B). It is possible to improve by dissipating the metal plate A quickly.

이상에서 설명한 바와 같이 본 발명은 대형 차량인 트럭이나 버스에 식품을 보관하고자 하는 보관함을 구비하고, 이 보관함의 외측벽 일측에는 전류의 흐름에 따라 흡열 및 방열하는 열전소자를 구비하여 상기 흡열, 방열 효과로 상기 보관함의 내부 온도를 냉각, 가열하여 줌으로써, 식품을 냉장하기 위하여 차량의 냉방장치를 가동하거나 혹은 보온하기 위하여 별도의 보온 장치를 구비하지 않고도 간단하면서 편리하게 이용할 수 있는 효과를 제공하게 되는 것이다.As described above, the present invention includes a storage box for storing food in a truck or a bus, which is a large vehicle, and one side of the outer wall of the storage box is provided with a thermoelectric element that absorbs and dissipates according to the flow of current. By cooling and heating the internal temperature of the storage box, it is possible to provide an effect that can be used simply and conveniently without having to provide a separate thermostat to operate or keep the air conditioner of the vehicle in order to cool food. .
