Description

수경재배 화분의 공기정화장치{Air purifier of hydroponic culture}Air purifier of hydroponic plant

본 고안은 수경재배 화분의 공기정화장치에 관한 것으로서, 더욱 상세하게는 실내공기가 화분 내측으로 유입된 뒤 활성탄 및 공기정화식물의 뿌리에 의해 실내의 각종 유해물질이 흡착 제거되도록 하되 양액이 부족할 경우 이를 감지하여 모터를 정지시킴으로써, 식물의 고사를 막고 또한 양액이 공기와 접하는 통로를 마련하여 모터가 가동되지 않더라도 용존산소량이 부족하지 않도록 한 수경재배 화분의 공기정화 장치에 관한 것이다.The present invention relates to an air purifying device for hydroponic cultivation pots, and more specifically, when indoor air is introduced into the pots, various harmful substances in the room are adsorbed and removed by the roots of activated carbon and air purifying plants. The present invention relates to an air purifying device for hydroponic cultivation pots, which stops the motor by detecting this and prevents the death of the plant and provides a passage through which the nutrient solution is in contact with the air so that the amount of dissolved oxygen is not insufficient even when the motor is not operated.

일반적으로 수경재배 화분은 하이드로볼 및 양액을 이용한 식물재배법으로써 흙을 사용하지 않는 특징을 갖는다. 수경재배 화분은 하이드로볼 및 식물 뿌리가 담기는 내통이 구비되며 내통과 화분 사이는 약간의 간격이 떨어져서 식물 뿌리가 숨을 쉴 수 있도록 해야 된다.Generally, hydroponic cultivation pots are characterized by not using soil as a plant cultivation method using hydroball and nutrient solution. Hydroponic cultivation pots should be equipped with inner bowls containing hydroballs and plant roots, with a slight gap between the inner pots and the pots, allowing plant roots to breathe.

이러한 수경재배 화분은 다양한 용도로 사용되는데 실내공기를 정화시키는 장치가 국내 실용 제297407호로 등록된 바 있다. 이는 식물이 심어진 다수개의 내통, 외통 및 팬 모터로 구성된다. 모터로 팬이 회전되면 실내공기가 화분 내측으로 유도된 뒤 내통을 통과하면서 활성탄에 의해 실내의 유해물질이 흡착 제거되는 방식이다.Such hydroponic cultivation pots are used for various purposes, and the device for purifying indoor air has been registered in Korean Utility No. 297407. It consists of a number of inner cylinders, outer cylinders and fan motors planted. When the fan is rotated by a motor, indoor air is guided to the inside of the flower pot and then passed through the inner cylinder.

그러나 종래의 선 등록된 공기정화 장치는 외통 내부에 내통을 배열시키기 때문에 별도의 밀폐수단이 없어서 팬이 가동될 경우 내통과 내통 사이 틈으로 바람이 누설되어 공기정화능력이 떨어지는 단점이 있었으며, 특히 모터는 양액의 수위에 관계없이 가동되는 것이므로 양액이 부족할 경우 팬이 작동되면 식물 뿌리가 말라 고사되는 등의 단점이 있었다.However, since the conventional pre-registered air purifying device arranges the inner cylinder inside the outer cylinder, there is no separate sealing means, when the fan is operated, the air leaks into the gap between the inner cylinder and the inner cylinder, thereby degrading the air purification capacity. Since it is operated regardless of the level of nutrient solution, there was a disadvantage that the plant roots dry out when the fan is operated when the nutrient solution is insufficient.

국내 공개특허 제2002-20156호는 화분에 팬과 모터를 일체형으로 제작한 공기정화장치가 제안된 바 있으나, 이것 역시 양액의 수위를 감지하는 센서장치가 제시되지 않아 식물 뿌리가 고사될 위험성이 있으며, 팬이 가동되는 동안 외부공기가 하이드로볼 및 숯으로부터 유입된 뒤 화분 밖으로 배기되는 형태이므로 식물이 심어진 하이드로볼에 이물질이 누적되어 쌓이면 바람이 원활하게 유입되지 않아 공기정화능력이 떨어지고, 양액통이 별도 구비되므로 구성이 복잡한 등의 단점이 있었다.Korean Patent Laid-Open No. 2002-20156 has proposed an air purifying device in which a fan and a motor are integrated in a flower pot, but this also has a risk of plant roots being killed because a sensor device for detecting the level of nutrient solution is not presented. When the fan is running, the external air is introduced from the hydroball and charcoal and then exhausted out of the pot. When foreign matter accumulates and accumulates in the planted hydroball, air does not flow smoothly. There was a disadvantage such as complicated configuration.

본 고안은 종래의 문제점을 감안하여 개발한 것으로서, 본 고안의 목적은 실내공기를 화분 내측으로 유입시켜 활성탄 및 공기정화식물의 뿌리로 유해물질이 흡착 제거되도록 하되 양액의 수위를 감지하여 양액이 부족할 경우 팬의 가동을 정지시킴으로써, 식물 뿌리가 말라 죽는 것을 방지시키고 특히 팬이 정지되더라도 양액이 실내공기와 접하여 용존산소량이 부족하지 않도록 한 수경재배 화분의 공기정화장치를 제공함에 있다.The present invention was developed in view of the conventional problems, and an object of the present invention is to allow indoor air to flow into a pot to allow harmful substances to be adsorbed and removed from the roots of activated carbon and air purifying plants, but the amount of nutrient solution may be insufficient by detecting the level of nutrient solution. In this case, by stopping the operation of the fan, to prevent plant roots from drying out, and in particular, even if the fan is stopped to provide an air purifying device of hydroponic cultivation pots so that the nutrient solution is in contact with the indoor air and the oxygen content is not short.

상기 목적을 달성하기 위하여 본 고안은 식물이 식재된 내통을 갖는 수경재배 화분에 있어서, 다수개의 내통이 상부에 놓이면 양액에 잠기는 하단의 양액출입구를 제외하고 내부를 밀폐시키는 밀폐통, 밀폐통과의 사이에 공기통로가 형성되어 양액의 용존산소량이 증가되도록 밀폐통이 놓이는 외통 그리고 실내 공기를 밀폐통 내부로 유입시킨 뒤 각 내통의 통풍망으로 공급하여 내통의 활성탄 및 공기정화식물의 뿌리에서 공기 중의 유해물질이 걸러지도록 팬 및 모터를 갖는 모터케이스로 구성되어 있다.In order to achieve the above object, the present invention is a hydroponic cultivation pot having a planted inner cylinder, in which a plurality of inner cylinders are placed in an upper side of a closed container for sealing the interior except for a nutrient solution inlet immersed in the nutrient solution. Air passages are formed in the tank to allow the dissolved oxygen of the nutrient solution to increase, and the air inside the sealed cylinder is introduced into the sealed cylinder, and then supplied to the ventilation net of each inner cylinder, and the harmful air in the air from the roots of the activated carbon of the inner cylinder and the air purification plant. It consists of a motor case with a fan and a motor to filter the material.

이하 본 고안의 바람직한 실시예를 첨부 도면에 따라 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 고안 공기정화장치의 사시도 이고, 도 2는 본 고안 공기정화장치의 단면도 이다. 본 고안은 하이드로볼(51) 및 활성탄(52)이 내장된 다수개의 내통(10)이 구비되고, 이들 내통(10)을 받쳐주는 밀폐통(20)이 구비된다.1 is a perspective view of an air purifier of the present invention, and FIG. 2 is a cross-sectional view of the air purifier of the present invention. The present invention is provided with a plurality of inner cylinders 10 in which the hydroball 51 and the activated carbon 52 are built, and a closed cylinder 20 supporting these inner cylinders 10 is provided.

밀폐통(20)은 하단에 다수개의 양액출입구(23)가 형성되며 상판(21)에는 내통(10)의 상단이 끼워져 걸쳐지는 받침구멍(22)이 형성된다. 그리고 밀폐통(20)이 끼워지는 외통(40)이 구비된다. 외통(40)과 밀폐통(20)의 사이에는 공기가 통하는 공기통로(41)가 형성되어 양액이 공기와 접하여 용존산소량이 부족하지 않도록 구성된다.The sealing cylinder 20 has a plurality of nutrient solution inlet 23 is formed at the lower end and the support plate 22 is formed in the upper plate 21 is fitted with the upper end of the inner cylinder (10). And the outer cylinder 40 in which the sealing cylinder 20 is fitted is provided. An air passage 41 through which air flows is formed between the outer cylinder 40 and the sealed cylinder 20 so that the nutrient solution is in contact with the air so that the amount of dissolved oxygen is not insufficient.

그리고 내통(10)의 외주면에는 통풍망(11)이 형성되며 이 통풍망(11)으로 실내공기의 자유로운 출입이 이뤄진다. 그리고 내통(10)의 하단에는 외통(40)에 담긴 양액을 식물(50) 뿌리가 흡수하도록 해주는 양액통로(12)가 형성된다.And a ventilation net 11 is formed on the outer circumferential surface of the inner cylinder 10, the free entry of the indoor air is made to the ventilation net (11). And at the bottom of the inner barrel 10 is a nutrient passage 12 to allow the plant 50 to absorb the nutrient solution contained in the outer cylinder 40.

밀폐통(20)에는 양액의 수위를 측정하기 위한 수위계(60)가 꼽히는 수위계홀더(22b)가 형성되어 양액의 수위를 일정하게 유지시킬 수 있다. 양액의 최저수위를 알 수 있으며 양액을 보충할 때 최고수위를 표시해 주므로 양액을 정량 공급할 수 있으며 후술할 수위감지 전극봉에서 최저수위를 감지하여 모터를 정지시키더라도 그 최저수위가 수위계(60)에서 표시되므로 모터 정지의 원인이 최저수위라는 것을 소비자가 알 수 있게 해준다.In the sealed container 20, a water level holder 22b in which a water level meter 60 for measuring the water level of the nutrient solution is formed is formed to maintain a constant level of the nutrient solution. The lowest level of the nutrient solution can be seen and the highest level is displayed when replenishing the nutrient solution so that the nutrient solution can be supplied quantitatively. Even when the motor is stopped by detecting the lowest level in the water level sensing electrode to be described later, the lowest level is displayed on the water level gauge (60). This allows the consumer to know that the cause of the motor stop is at the lowest level.

본 고안은 밀폐통(20)의 상판(21) 일측에 케이스구멍(22a)에 끼워지는 모터케이스(30)가 구비된다. 모터케이스(30)는 팬(33) 및 모터(34)가 내장되며 상단은 흡입구(31) 하단은 배출구(32)가 형성된다. 그리고 하단에는 양액의 수위를 전기적으로 감지하는 수위감지 전극봉(35)이 구비되어 양액의 최저수위가 감지되면 모터(34)의 작동을 정지시키도록 구성된다. 또한 모터케이스(30)는 모터(34)의 세기를 조절하여 풍량을 조절하는 수단 및 실내공기의 오염 정도를 측정하여 표시해주는 디스플레이수단이 더 구비된다. 미설명부호 13은 내통(10)을 세울 수 있는 지지리브를 나타낸다.The present invention is provided with a motor case 30 that is fitted to the case hole (22a) on one side of the top plate 21 of the sealed cylinder (20). Motor case 30 has a fan 33 and the motor 34 is built in the upper end of the inlet port 31, the discharge port 32 is formed. And at the bottom is provided with a level sensor electrode 35 for electrically sensing the level of nutrient solution is configured to stop the operation of the motor 34 when the lowest level of nutrient solution is detected. In addition, the motor case 30 further includes a means for adjusting the air volume by adjusting the intensity of the motor 34 and a display means for measuring and displaying the pollution degree of the indoor air. Reference numeral 13 denotes a support rib capable of raising the inner cylinder 10.

이처럼 구성된 본 고안은 외통(40) 내부에 밀폐통(20)이 공기통로(41)를 사이에 두고 설치되므로 실내공기가 양액과 접하여 이의 용존산소량이 부족해지지 않는다. 그리고 밀폐통(20)에는 다수개의 내통(10)이 받침구멍(22)으로 끼워져 놓이며 이들의 하단은 양액에 잠겨 양액통로(12)를 따라 식물 뿌리가 양액을 흡수하도록 구성된다.The present invention configured as described above is installed in the outer cylinder 40 with the sealed cylinder 20 interposed between the air passage 41, so that the indoor air is in contact with the nutrient solution and the amount of dissolved oxygen thereof is not insufficient. In addition, a plurality of inner cylinders 10 are inserted into the receiving holes 22 in the sealed cylinder 20 and the lower ends thereof are immersed in the nutrient solution, and the plant roots are configured to absorb the nutrient solution along the nutrient solution passage 12.

모터케이스(30)가 밀폐통(20)의 상부에 설치되면 이의 하단 전극봉(35)이 양액에 잠겨 전기가 통하므로 양액이 정상 수위로 감지된다. 따라서 모터(34)를 작동시키면 전원이 공급되어 팬(33)이 회전되므로 실내공기가 흡입구(31)와 배출구(32)를 거쳐 내통(10)으로 향하고 이의 통풍망(11)을 타고 내통(10)으로 들어가 활성탄(52) 및 공기정화식물의 뿌리를 통과하면서 공기 중에 포함된 각종 유해물질인 벤젠, 클로로에틸렌, 포름알데히드, 미세먼지, 황사 및 꽃가루 등이 걸러진다. 그리고 공기정화식물의 뿌리는 이들 유해물질로 형성되는 미생물을 흡수하므로 결국 뿌리에서 유해물질이 제거된다. 또한 양액의 습기를 머금고 배출되어 실내공기가 맑고 쾌적해진다.When the motor case 30 is installed on the upper side of the sealed container 20, the lower electrode 35 thereof is immersed in the nutrient solution, so that the nutrient solution is detected at the normal level. Therefore, when the motor 34 is operated, the power is supplied and the fan 33 is rotated. Therefore, the indoor air is directed to the inner cylinder 10 through the inlet 31 and the outlet 32, and rides through the ventilation network 11 to the inner cylinder 10. ) Through the roots of the activated carbon 52 and air purification plants to filter out various harmful substances such as benzene, chloroethylene, formaldehyde, fine dust, yellow sand and pollen. And the roots of air purification plants absorb the microorganisms formed by these harmful substances, which eventually removes the harmful substances from the roots. In addition, the moisture in the nutrient solution is discharged to make the indoor air clear and comfortable.

양액의 부족할 경우 전극봉(35)에 전류가 통하지 않으므로 최저수위로 감지되어 모터(34)로 공급되는 전원이 차단된다. 따라서 식물(50) 뿌리가 건조해져 말라 죽는 일이 방지된다. 그리고 밀폐통(20)과 외통(40)의 사이에 공기통로(41)가 형성되고 밀폐통(20) 하단에 형성된 양액출입구(23)를 따라 밀폐통(20) 내부로 양액이 자유롭게 출입되므로 양액의 용존산소량이 부족해지지 않는다.If the nutrient solution is insufficient, since the current does not pass through the electrode 35 is detected at the lowest water level and the power supplied to the motor 34 is cut off. Therefore, the roots of the plant 50 are dried to prevent drying. An air passage 41 is formed between the sealed cylinder 20 and the outer cylinder 40, and the nutrient solution flows freely into the sealed cylinder 20 along the nutrient solution inlet 23 formed at the bottom of the sealed cylinder 20. Does not run out of dissolved oxygen.

본 고안은 실내공기가 식물로 강제 순환되므로 바람에 영향을 받지 않고 생육할 수 있는 식물이 식재되어야 한다.The present invention is forced to circulate indoor air plants, so plants that can grow without being affected by the wind should be planted.

이상에서와 같이 본 고안에 따르면 양액의 수위를 감지하여 최저수위일때 모터로 공급되는 전원을 자동 차단시킴으로 식물의 고사가 방지된다. 그리고 밀폐통 내부의 양액이 양액출입구를 타고 외통과 밀폐통 사이로 자유롭게 출입되어 실내공기와 접하므로 용존산소량이 부족해지지 않는 효과가 있다.As described above, according to the present invention, the water level of the nutrient solution is sensed, thereby preventing the death of the plant by automatically shutting off the power supplied to the motor at the minimum level. In addition, the nutrient solution inside the sealed container freely enters and goes between the outer cylinder and the sealed container through the nutrient solution inlet and comes into contact with indoor air, so that the amount of dissolved oxygen is not insufficient.
