또, 상기 공기냉각.가열실(15)에는 온풍을 공급하기 위한 공기가열히터(23)가 장착되어 있다.The air cooling and heating chamber 15 is further equipped with an air heating heater 23 for supplying warm air.

그리고 상기 배기실(16)에는 배기팬(24)이 설치되어 있고 측면에 배기구(16b)가 천공되어 있다.In the exhaust chamber 16, an exhaust fan 24 is provided, and an exhaust port 16b is drilled in the side surface.

상기 공기냉각.가열실(15)과 배기실(16)의 사이에는 열전모듈(50)이 설치되어 있는데 이 열전모듈(50)은 열전소자(51)와 그 양측의 방열판(52)과 냉열판(53)으로 구성되며 방열판(52)은 배기실(16) 쪽에 그리고 냉열판(53)은 공기냉각.가열실(15) 쪽에 위치하게 한다.The thermoelectric module 50 is installed between the air cooling and heating chamber 15 and the exhaust chamber 16. The thermoelectric module 50 includes a thermoelectric element 51, heat dissipating plate 52 and a cooling plate on both sides thereof. The heat sink 52 is located on the exhaust chamber 16 side and the cold plate 53 is located on the air cooling / heating chamber 15 side.

또 상기 방열판(52)에는 히트파이프(60)의 일단을 연결하고 히트파이프(60)의 타단은 배기팬(24)의 공기유입통로 상에 설치한다. 상기 히트파이프(60)의 타단은 배기팬(24)의 공기유입통로까지만 설치할 수도 있지만 배기팬(24)의 공기유출통로에까지 더 연장 설치할 수도 있다.In addition, one end of the heat pipe 60 is connected to the heat sink 52, and the other end of the heat pipe 60 is installed on the air inflow passage of the exhaust fan 24. The other end of the heat pipe 60 may be installed only up to the air inflow passage of the exhaust fan 24, but may be further extended to the air outflow passage of the exhaust fan 24.

상기 뚜껑(30)에는 조명장치(40)가 설치되는데 그 전면에는 투광판(41)이 노출되어 있고, 상기 공기냉각.가열실(15)의 전방에 위치하는 한쪽 구석에는 온풍출구(31)가 형성되고 이 온풍출구(31)는 원판(32)으로 가려지며 원판(32)은 열을 받 으면 원적외선을 방출하는 맥반석이 혼합된 합성수지나 아니면 맥반석 원석으로 되어 있다.The lid 30 is provided with a lighting device 40, the front of the floodlight plate 41 is exposed, the hot air outlet 31 is located in one corner located in front of the air cooling, heating chamber 15. The hot air outlet 31 is formed by the disk 32, the disk 32 is made of synthetic resin or ganban stone ore mixed with ganban stone that emits far infrared rays when heated.

또, 뚜껑(30)의 온풍출구(31)의 옆에는 리모컨(도시되지 않음) 신호를 수신하는 수신부(70)와 공기정화, 환기, 온풍, 건조 등을 표시하는 표시등(71)이 배치되어 있다.In addition, beside the hot air outlet 31 of the lid 30, a receiving unit 70 for receiving a remote control (not shown) signal and an indicator light 71 for displaying air purification, ventilation, warm air, and drying are disposed. have.

상기와 같이 구성된 본 발명은 실내공기를 환기시키고자 할 경우에는 리모컨 등의 별도의 조작수단에 의하여 배기팬(24)을 구동하면 실내공기가 유입구(16a)를 통해 배기실(16)로 들어가 배기팬(24)에 의해 배기구(16b)를 통해 외부로 배출되고, 실내공기를 정화하고자 할 경우에는 순환팬(20)을 구동하면 실내공기가 유입구(14a)를 통해 공기정화실(14)로 유입하여 공기정화필터(21)를 거쳐 순환팬(20)을 통과하고 다시 격벽(11)의 통로(11a)를 거쳐 공기냉각.가열실(15)로 들어간 다음 유출구(15a)로 유출된다. According to the present invention configured as described above, when the exhaust fan 24 is driven by a separate operation means such as a remote controller when the indoor air is to be ventilated, the indoor air enters the exhaust chamber 16 through the inlet 16a and is exhausted. When the exhaust fan 16 is discharged to the outside through the exhaust port 16b and the indoor air is to be purified, the indoor air is introduced into the air purification chamber 14 through the inlet port 14a when the circulation fan 20 is driven. After passing through the circulation fan 20 through the air purification filter 21, and again through the passage (11a) of the partition wall 11 enters the air cooling / heating chamber (15) and then flows out to the outlet (15a).

상기 과정에서 공기정화실(14)에서 공기가 정화된 다음 공기냉각.가열실(15)을 거쳐 빠져나오게 될 때 공기냉각.가열실(15)의 공기가열히터(23)가 가동중이면 온풍이 나오게 되고 공기냉각.가열실 공기가열히터(23)의 전원이 꺼져있고 대신 열전모듈(50)이 가동 중이면 냉풍이 공급되며, 둘 다 전원이 꺼져있으면 실온상태의 정화된 공기가 공급된다.When the air is purified in the air purification chamber 14 and then exits through the air cooling / heating chamber 15 in the above process, if the air heating heater 23 of the air cooling / heating chamber 15 is in operation, the warm air is When the power of the air heating heater 23 is turned off and the thermoelectric module 50 is turned on, cold air is supplied, and both are supplied with purified air at room temperature.

상기 열전모듈(50)은 열전소자(51)에 의해 공기정화실(14)에서 공기냉각.가열실(15)로 유입된 공기 중의 열을 흡수하여 배기실(16)의 배기로 방열함으로써 실내공기를 냉각해주는 기능을 가진 것으로 실내온도를 낮추어 주는 작용을 한다. 열 전소자(51)의 양쪽에 적층되어 있는 냉열판(53)과 방열판(52)은 공기와 열전소자(51) 사이의 열교환이 원활하도록 도와준다. The thermoelectric module 50 absorbs heat from the air introduced into the air cooling / heating chamber 15 from the air purification chamber 14 by the thermoelectric element 51 and radiates the heat to the exhaust of the exhaust chamber 16. It has a function to cool the room to lower the temperature. The cold plate 53 and the heat sink 52 which are stacked on both sides of the thermoelectric element 51 help the heat exchange between the air and the thermoelectric element 51 to be smooth.

또, 상기 열전모듈(50)에는 히트파이프(60)가 연결되어 있는데 이 히트파이프(60)의 타단은 배기실(16)의 공기유입통로 상에 위치하도록 하거나 히트파이프(60)를 더 연장하여 배기실의 공기배출통로에까지 연장설치할 수도 있다. 상기 히트파이프(60)는 그 내부에 열 에너지를 전달하는 열 전달매체가 충전되어 있고 외부에는 다수의 방열핀이 설치되어 있기 때문에 열전소자가 가지고 있는 열을 신속하게 운반하여 배기중에 방열하는 역할을 한다.In addition, a heat pipe 60 is connected to the thermoelectric module 50, and the other end of the heat pipe 60 is positioned on the air inflow passage of the exhaust chamber 16 or further extends the heat pipe 60. It may be extended to the air exhaust passage of the exhaust chamber. Since the heat pipe 60 is filled with a heat transfer medium that transfers thermal energy therein and a plurality of heat dissipation fins are installed outside, the heat pipe 60 quickly transfers heat of the thermoelectric element and serves to radiate heat in the exhaust. .

상기 열전모듈(50)이나 히트파이프(60)는 이미 널리 알려진 것이므로 그 구체적인 설명은 생략한다.Since the thermoelectric module 50 and the heat pipe 60 are already well known, detailed description thereof will be omitted.

또 상기 조명장치(40)는 환기와 온풍가열 등의 다른 기능의 운전상태와 관계없이 별도로 조작된다.In addition, the lighting device 40 is operated separately regardless of the operating state of other functions such as ventilation and hot air heating.
