Abstract
본 고안은 관상어,활어의 수조(1)에 이용되는 냉온수기(3)에 관한 것으로 수조(1),여과기(2),냉온수기(3),순환펌푸(4)로구성되며 냉온수기(3)는 수조(1)내 어류의성질에 알맞은 수온을 유지하는 중요한 역할을 하고 있다.The present invention relates to a cold and hot water heater (3) used in the aquarium (1) of the ornamental fish, live fish consists of a water tank (1), a filter (2), a cold and hot water machine (3), a circulation pump (4), the cold and hot water machine (3) is a water tank (1) It plays an important role in maintaining the water temperature suitable for the nature of the fish.
종래의 수온유지방법은 수온을 높일 경우 수조(1)내에 전기히터를 넣어 가열하는 전기히터식으로 히터주변과의 수온차가심하여 어류의 스트레스 요인이 되고 있다.또한 하절기수온이 상승하였을 때 냉매(프레온)를 이용한 냉각기를 사용하는 경우가 대부분이며 이냉각기는 진동과소음 팬으로부터 발생되는 더운공기등이 주변환경을 저해하고 있다.특히 프레온(CFC)은 대기오염의 주범으로 알려지고 있어 더욱 큰 문제점을 안고 있다.Conventional water temperature maintenance method is an electric heater that puts an electric heater in the water tank 1 when the water temperature is increased, and the difference in water temperature between the heater and the heater is a cause of fish stress. Also, when the summer temperature rises, the refrigerant (freon) In most cases, this air conditioner is affected by hot air generated from vibration and noise fans, and especially the freon (CFC) is known as the main cause of air pollution. Holding it.
이와 같이 수조에 이용되는 냉온수기(3)의 문제점을 보완하는 방법으로 열전반도체(3-1)를 이용하고자 한다. 수조(1)의 수온유지는 사람이 음용하는 식수처럼 순간적으로 차갑거나 뜨거운 것을 요구하는 것이 아니고 수시간또는 계속해서 수조(1)의 저수된물이 어류의 알맞은 수온으로 상시유지시키는데 목적이 있으므로 열전반도체(3-1)를 이용한 냉온수기(3)의 기능은 매우효과적이다.As such, the thermoelectric semiconductor 3-1 is to be used as a method of compensating the problem of the cold and hot water heater 3 used in the water tank. The water temperature of the water tank 1 is not required to be cold or hot instantaneously like drinking water for human consumption, but it is intended to keep the water in the water tank 1 at a proper water temperature for several hours or continuously. The function of the cold / hot water machine 3 using the semiconductor 3-1 is very effective.
보다 구체적으로는 열전반도체(3-1)의 원리를 이용하여 수조(1)의 수온이 높은하절기에는 냉각작용을 하도록하고 수온이 내려가는 동절기에는 열전반도체(3-1)극성을 전환시켜 가열작용을 하도록하므로서 수온을 상승또는 강하시켜 어류의 성질에 알맞은 수온을 유지시키는 것을 특징으로 할수 있다. 뿐만아니라 계절별로 냉각기,히터기를 설치하는 번거러움을 해소할수 있으며 냉매를 사용하지 않아 대기오염을 방지할수 있고 무소음,무진동 정확한 온도조절기능등이 용이하고 대기 및 생활환경 개선을 높이는 효과를 제공한다.More specifically, by using the principle of the thermoelectric semiconductor (3-1) to cool in the summer when the water temperature of the water tank (1) is high, in the winter when the water temperature decreases the polarization of the thermoelectric semiconductor (3-1) to switch the heating action By raising or lowering the water temperature, it is possible to maintain the water temperature suitable for the properties of the fish. In addition, it can eliminate the hassle of installing a cooler and heater according to seasons, prevents air pollution by using no refrigerant, and makes it easy to control noise and vibration-free accurate temperature control and improve the air and living environment.
Description
본 고안은 관상어,활어의 수조에 관한 것으로서 수조내에 보관되는 어류는 어류성질에 따라 적정한 수온을 유지시켜주어야 하는데 냉수성 어류에는 냉각기를 사용하여 저수된물을 차갑게 해주고 온대성또는 아열대성 어류는 수온을 올려주기 위하여 전기식히터를 이용하여 수온을 상승시켜 주는 것이 보편적인 방법이다.The present invention relates to the aquarium of ornamental fish and live fish, and the fish kept in the tank should maintain the proper water temperature according to the fish properties. For the cold water fish, the chilled water is cooled by using a cooler and the temperature of the tropical or subtropical fish is It is a common way to raise the water temperature using an electric heater to raise the temperature.
보다 상세하게는 우리나라의 하절기에는 높은 외부기온으로 수조의 수온이 자연이 상승하여 섭씨10도 내외의 수온을 요구하는 어류는 폐사하게 되며 외부기온이 낮은 겨울철또한 수조 수온이 영하로 하강하여 동사하게 된다. 이같은 문제점을 해결하는 방법으로 수온이 높을때는 냉매를 이용한 냉각기에 저수된물을 통과시켜 수온을 낮춰주고 있으나 수조의 저수량에 따라 차이는 있지만 섭씨1도씨의 수온을 낮추려면 오랜시간의 냉각기 가동이 불가피하고 이때 콤푸레셔의 가동은 소음과 진동 더운공기등을 발생시켜 생활환경을 저해하고 있다.또한 냉매로 이용되는 프레온가스는 대기환경을 오염시키고 오존층을 파괴하므로 대체기기의 필요성이 절실한 현실이다 뿐만아니라 동절기 수조에저수된 물수온을 올리는 방법으로 이용되고 있는 전기 히터방식은 히터주변의 수온차이가 심하여 수온에 매우 민감한 어류에 상당한 스트레스를 주고 전력량의 소모도 간과할수 없는 실정이다.이같이 종래의 사용기기인냉각기와 히터기는 계절에 따라 설치와 철거를 반복하여야 하는 불편이따르고 앞에서 열거한 여러 가지 문제점을 안고 있다.More specifically, in summer, the water temperature of the tank rises due to the high external temperature, and the fish that requires water temperature of around 10 degrees Celsius dies. In winter, when the external temperature is low, the water temperature drops to below freezing. . As a way to solve this problem, when the water temperature is high, the water is lowered by passing the stored water to the cooler using the refrigerant, but the temperature of the water tank is different, but it is inevitable to operate the cooler for a long time to lower the water temperature of 1 degree Celsius. At this time, the operation of the compressor causes noise and vibration, which causes hot air, which hinders the living environment.In addition, the need for a replacement device is urgent as freon gas used as a refrigerant pollutes the atmosphere and destroys the ozone layer. The electric heater method used to raise the water temperature stored in the water tank is a situation where the temperature difference around the heater is so great that it causes considerable stress on fish that are very sensitive to the water temperature and the consumption of electric power cannot be overlooked. And heaters must be installed and dismantled according to the season. It can solve the problems by following these inconveniences listed above.
본 고안은 상기와 같은 문제점을 해결하기 위한 것으로써 열전반도체를 이용한 냉온수겸용기로 사용할 수 있고 본래의 수온조절기능을 제공할 뿐아니라 대기환경개선에 기여함을 그 목적으로 한다.The present invention is to solve the problems as described above can be used as a cold and hot water combiner using a thermoelectric semiconductor and to provide an original temperature control function as well as contribute to the improvement of the atmospheric environment.
상기와 같은 목적을 달성하기 위한 본고안은 냉온수기(3)의 몸체에 해당하는 외부집수통(3-2)과 내부집수통(3-3)에 저수된물을 입수시키는 취수구(3-4)와 내부집수통(3-3)에서 순환펌푸(4)로 이송시키는 배수구(3-5)가 있으며 내부집수통(3-3)내부에서 물의 흐름을 유도하는 수로판막(3-6)을 포함하여 구성된다.The present invention for achieving the above object is an intake port (3-4) for receiving the water stored in the outer sump (3-2) and the inner sump (3-3) corresponding to the body of the cold and hot water heater (3). And a drain port (3-5) for transferring from the inner sump (3-3) to the circulation pump (4) and includes a waterway valve (3-6) for inducing the flow of water in the inner sump (3-3). It is configured by.
또한 본고안에 있어서 몸체에 해당되는 내,외부집수통은 내구성이 강하고 열전도율이 높은 얇은재질(스테인레스,동,합성수지,세라믹류등)을 이용하여 원형이나 각형으로 제작할수 있으나 열전반도체의 효율을 극대화하기위하여 원형보다는 각형을 사용하는 것이 더 바람직하다 도2와 같이 각형의 외부집수통(3-2)의외판에 여러개의 열전소자를 밀착하여 부착한다.In addition, in this paper, the inner and outer water collecting tanks corresponding to the body can be manufactured in circular or square shape using thin materials (stainless steel, copper, synthetic resin, ceramics, etc.) with high durability and high thermal conductivity. For the sake of convenience, it is more preferable to use a rectangle rather than a circle. As shown in FIG. 2, a plurality of thermoelectric elements are closely attached to an outer plate of an outer collecting container 3-2.
또한 본 고안에 있어서 외부집수통(3-2)와 내부집수통(3-3)사이에 낮은온도에도얼지않는 에틸렌그리콜이나 프로필렌그리콜액과 물을적당히 혼합한액체를 채워넣는다. 외부집수통(3-2)외판에 부착된 열전반도체(3-1)의 작용에 의하여 그 액체는 가열되거나 냉각되게 된다.In addition, in the present invention, between the outer sump (3-2) and the inner sump (3-3) is filled with a liquid mixed appropriately with ethylene glycol or propylene glycol liquid and water even at low temperatures. The liquid is heated or cooled by the action of the thermoelectric semiconductor 3-1 attached to the outer shell of the outer container 3-2.
또한 본 고안에 있어서 내부집수통(3-3)좌,우에 부착된 취수구(3-4)의 단면을 배수구(3-5)의 단면보다 크게하여 취수된물이 내부집수통(3-3)을 느린 유속으로 지나가게 하므로서 내부집수통(3-3)외부에 있는 액체온도의 전달을 더 많이 전도되도록한다.In addition, in the present invention, the cross section of the water intake port 3-4 attached to the left and right sides of the internal water collection container 3-3 is larger than the cross section of the drain port 3-5. By passing through at a slow flow rate, the transmission of the liquid temperature outside the sump (3-3) is more conducted.
또한 본 고안에 있어서 도4와 같이 내부집수통(3-3)내부에 여러개의 수로판막(3-6)을 부착하여 취수구(3-4)로부터 유입된물이 수로판막(3-6)사이로 흐르도록 유도하여 마치 긴 파이프를 통과하는효과를 얻으므로서 내부집수통(3-3)외부에있는 액체로부터 보다 더 효과적으로 수온을 낮추거나 올릴 수 있다.In addition, in the present invention, as shown in FIG. 4, a plurality of water channel valves 3-6 are attached to the inside of the water collecting container 3-3, and water flowing from the water intake port 3-4 is between the water channel valves 3-6. It is possible to lower or raise the water temperature more effectively from the liquid outside the internal sump container (3-3) by inducing the flow to get through the long pipe.
또한 본 고안에 있어서 수조(1)외부기온의 변화에 의하여 흡열(냉각)에서 발열(가열), 가열에서 냉각으로 열전반도체(3-1)의 작용변화를 주고자할때에는 공급전원(직류)의 극성을바꾸워(전환)주면 가능하게되므로 외부집수통(3-2)은 냉각수, 온수통 으로 겸하여사용 할수있는잇점이있다.In addition, in the present invention, when a change in the external temperature of the water tank (1) is intended to change the action of the thermoelectric semiconductor (3-1) from endothermic (cooling) to exothermic (heating) and from heating to cooling, It is possible to change the polarity (switch), so the external sump tank (3-2) can be used as a coolant or hot water tank.
또한 본고안에 있어서 수조(1)의 수온이 적정수온에 도달하거나 변동이있을때 현재사용하고있는 자동온도조절기와 수온감지센서를 이용하여수조(1)저수지내에 감지센서를 설치하고 수온을감지하면 자동온도조절기는 선택한수온에도달하였을경우 열전반도체(3-1)에 공급하는 전원을차단하고 변동시에는 전원을 접속하는 동작을 반복하여 항상 일정한 수온을 유지하도록할수있다.In addition, in this paper, when the water temperature of the water tank (1) reaches the proper water temperature or there is a fluctuation, the sensor is installed in the reservoir (1) reservoir by using the thermostat and the water temperature sensor currently in use. When the controller reaches the selected water temperature, the controller cuts off the power supply to the thermoelectric semiconductor (3-1) and repeats the operation of connecting the power in case of fluctuation, thereby maintaining a constant water temperature at all times.
또한 본 고안에 있어서 변형된구조로 외부집수통(3-2)를 제거하고 내부집수통(3-3)외판에 열전반도체(3-1)을 취부하여이용할 수도 있으며 또한 이를 직접수조(1)의 측벽부(1-1)나 바닥부(1-2)에 직접 부착이용하는 경우도 가능할것이나 그 효율이 낮아 비경제적이고 특히 좁은수조(1)공간에서 심한 수온 차이로인하여 어류에 스트레스를 가중시킬수 있으므로 바람직한 방법이라 볼 수 없다.In addition, in the present invention, the outer container (3-2) may be removed and the thermoelectric semiconductor (3-1) may be attached to the inner plate (3-3) of the inner container (3-3). It is also possible to use it directly on the side wall part 1-1 or the bottom part 1-2 of the tank. However, its efficiency is low and it is uneconomical. In particular, it may add stress to the fish due to the severe water temperature difference in the narrow tank (1) space. This is not a preferred method.
이상 설명한 본 고안은 그 기술적사상 또는 주요한 특징으로부터 벗어남이 없이 다른 여러 가지 형태로 실시될 수 있다 따라서 상기 실시예는 모든 점에서 단순한 예시에 지나지 않으며 한정적으로 해석되어서는 안된다.The present invention described above may be embodied in many different forms without departing from the spirit or main features thereof. Thus, the above embodiments are merely illustrative in all respects and should not be construed as limiting.
이와같은 본 고안의 수조냉온수기는 일반적 냉각기,전기히터기식의 문제점을 해결할 수 있고 정확한 온도조절,무소음,무진동,소형,경량화를 꽤할수 있으며 수명이 길뿐아니라 프레온(CFC)을 사용하지 않으므로 대기오염을 크게 줄일수 있는 효과를 제공한다.The water tank cold water heater of the present invention can solve the problems of general cooler and electric heater type, and it is able to control temperature accurately, noiseless, vibration free, small size and light weight, and it has a long life and does not use Freon (CFC). Provides significant reduction.
