Abstract

PURPOSE: A circulation fan for single-span greenhouse is provided to cool a motor with air current by arranging the motor at a place where air current is formed. CONSTITUTION: A cylindrical case(3,4) supports a drive motor and accommodates a wing(7). The cylindrical case has a size-reduced portion in the middle. In the size-reduced portion, the diameter of an air outlet is reduced to increase the air velocity. The cylindrical case has a ring for attaching and detaching a circulation fan. The drive motor is assembled and supported by three supporters within the cylindrical case. The drive motor is located in front of the wing to be cooled. The drive motor is axially assembled and moisture-resistant.

Description

단동온실형 순환팬{Single-span Greenhouse Circulation Fan}Single-dong Greenhouse Circulation Fan

유리온실이나 비닐하우스와 같이 외부와 피복재로 차단된 시설재배에서 온실내 균일한 온습도 분포, 적당한 기류형성, 상하수평 공기순환을 위한 순환팬의 제작에 관한 기술이다. It is a technique for manufacturing a circulation fan for uniform temperature and humidity distribution, proper airflow, and vertical and horizontal air circulation in greenhouses in facility cultivation, which is blocked by the exterior and covering materials such as glass greenhouses and vinyl houses.

온실재배는 외부의 공기유출입이 차단되는 피복재를 사용하는 구조를 기본으로 하고 있다. 이런 피복재에서는 공기가 차단되므로 온도와 습도가 외부와 차단되어 추운계절에도 작물재배가 가능하다. 그러나 외부와 차단되어 밀폐된 실내공기는 작물재배를 위한 온도관리는 원활하지만, 증발이나 증산에 따라 실내 습도가 과도하게 높아져 작물 생육에 장애를 줄 수가 있다. 또한 단동형 온실은 길이가 길고 높이가 2m 내외로 낮기 때문에 실내 공기가 정체되어 광량이 감소하거나 산란되는 등 작물재배에 나쁜 영향을 미친다. 따라서 온실내 정체공기의 순환과 습도의 제거등을 위하여 순환팬이 필요하다.Greenhouse cultivation is based on a structure that uses cladding to block external airflow. In these claddings, air is cut off, so temperature and humidity are cut off from the outside, allowing crop cultivation even in cold weather. However, the sealed indoor air is blocked from the outside and the temperature control for crop cultivation is smooth, but the room humidity is excessively increased due to evaporation or transpiration, which may interfere with crop growth. In addition, since the single-acting greenhouse has a long length and a low height of about 2m, indoor air is stagnant, which causes a bad effect on crop cultivation, such as a decrease in light quantity or scattering. Therefore, a circulation fan is required for circulation of stagnant air in the greenhouse and removal of humidity.

본 발명은 높이가 낮고 길이가 긴 온실내의 대면적에 공기 순환을 위하여 팬의 정압과 동압이 적절히 조화되는 팬을 구성함으로서 사용대수가 적어도 실내순환이 원만한 단동온실용으로 습도가 높은 온실내의 환경에 맞게 방습형 구조와 구동모터의 냉각을 동시에 해결한 순환팬을 구성하였다.The present invention constitutes a fan in which the static pressure and the dynamic pressure of the fan are properly harmonized for air circulation in the large area in the greenhouse with a low height and a long length. The circulation fan solved the moisture-proof structure and cooling of the drive motor.

일반적인 순환팬의 구조를 개선하여 동압과 정압이 동시에 적절하게 조화되도록 팬의 케이스를 원통형으로 길게 구성하고, 전단부 절반 정도를 직경이 적게하여 동압을 향상시키는 구조를 갖는다. 모터를 일반팬의 구조와 반대로 날개의 전면에 배치하여 날개로 인한 바람으로 모터를 냉각하게 하여 별도의 냉각팬을 사용하지 않는다. 이럴 경우 바람에 포함된 수분이 모터의 하우징과 축을 통해 모터내로 침입할 수 있으므로 별도의 방습형 구조의 축과 하우징 재료와 조립 방법을 사용한다. By improving the structure of a general circulation fan, the case of the fan is configured to have a cylindrical shape so that the dynamic pressure and the static pressure are properly harmonized at the same time, and the half of the front end portion has a diameter to improve the dynamic pressure. Contrary to the structure of the general fan, the motor is placed on the front of the blade to cool the motor by the wind caused by the blade, so that a separate cooling fan is not used. In this case, the moisture contained in the wind can enter the motor through the housing and the shaft of the motor, so a separate moisture-proof structure of the shaft and the housing material and the assembly method are used.

우리나라의 대부분 단동온실은 낮고 길이가 길어 실내 공기의 정체가 작물재배에 영향을 미치는 정도가 심하여 농산물 품질저하를 야기한다. 따라서 본 단동온실용 순환팬을 사용하면 적은 사용대수로 대면적의 공기를 순환시키므로 온실내 공기의 온도분포 균일, 과습제거, 기류형성으로 작물재배에 호조건을 만들어준다. Most Dandong greenhouses in Korea have low and long lengths, and the stagnation of indoor air affects crop cultivation so that the quality of agricultural products is reduced. Therefore, the use of this single-dong circulating fan circulates a large area of air with a small number of uses, thus creating favorable conditions for crop cultivation through uniform temperature distribution, dehumidification, and airflow in the greenhouse.

본 발명은 단동온실용의 순환팬에 관한 내용으로 기본적으로 전동모터를 사용하는 일반적인 팬의 기본적인 구성에서 크게 벗어나지 않는다.The present invention relates to a circulating fan for a single-dong greenhouse, and basically does not deviate significantly from the basic configuration of a general fan using an electric motor.

그러나 단동온실은 높이가 낮고 길이가 길고 온도변화가 자주발생하기 때문에 온실내가 과습으로 되기 쉬운 구조를 갖고 있어 일반적인 팬으로는 목적한 실내 온습도환경을 조절하는 것이 불가능하다. However, since Dandong greenhouses are low in height, long in length, and frequently change in temperature, the greenhouse has a structure that tends to be over-humidified. Therefore, it is impossible to control the intended indoor temperature and humidity environment with a general fan.

그림과 함께 개발한 단동온실용 순환팬을 상세하게 설명하면 다음과 같다. 원통형의 케이스(3,4)를 길게 구성하여 절반정도의 길이로 전반부와 후반부로 구분한다. 후반부(3)는 모터(9)를 지지하는 부분으로서 바람에 저항이 적은 3개의 "⊂" 형상의 지지대(8)로 케이스와 모터(9)를 조립지지한다. 모터(9)와 날개(7)는 직결구조로하고, 날개(7)에 의한 바람이 모터(9)를 통과하여 전반부로 진행한다. 원통형 케이스의 전반부(4)는 후반부(3)보다 직경을 적게하는 축소부(6)를 성형하여 유속을 빠르게하여 동압을 증가시키는 구조로 한다. 원통형 케이스의 양측 끝단부(1,2)는 라운딩으로 성형하여 강도를 높게한다. 케이스의 후반부(3), 즉 모터(9)가 고정되는 끝단부에는 안전망을 설치 만일의 안전사고와 이물질로 인한 날개(7)의 손상을 예방한다. 케이스의 외부에는 팬을 구조물에 설치할 수 있는 고리(5)를 부착한다.The following describes the circulating fan for the single-dong greenhouse developed with the drawings in detail. The cylindrical case (3,4) is made long and divided into the first half and the second half in about half the length. The second half 3 is a part for supporting the motor 9 and supports the case and the motor 9 by three "⊂" shaped supporters 8 with little resistance to wind. The motor 9 and the blade 7 have a direct connection structure, and the wind by the blade 7 passes through the motor 9 and proceeds to the first half. The first half portion 4 of the cylindrical case has a structure in which a reduction portion 6 having a diameter smaller than that of the second half portion 3 is formed to increase dynamic pressure by increasing the flow velocity. Both ends (1, 2) of the cylindrical case is molded by rounding to increase the strength. A safety net is installed at the rear end 3 of the case, that is, the end at which the motor 9 is fixed, to prevent damage of the wing 7 due to a safety accident and foreign matters. Attached to the outside of the case is a ring (5) to install the fan in the structure.

날개(7)에 의한 바람이 모터(9)를 지나서 배풍되는 구조의 본 순환팬은 바람에 포함된 수분이 모터(9)의 축이나 하우징을 통해 모터내에 침입하여 모터를 손상하게 할 수 있으므로 하우징과 축조립시에 별도의 방습자재를 사용한다. 또한 단상모터의 기동을 위하여 필요한 컨덴서를 사용하면 바람의 저항이 발생하고 배선을 따라 방수가 곤란하므로 켄덴서를 사용하지 않는 모터(9)를 선정 사용한다. 바람에 의한 기류로 모터(9)에서 발생하는 열을 충분히 냉각할 수 있으므로 모터자체에 별도의 냉각팬을 부착할 필요가 없어 제조원가를 저감할 수 있다. This circulation fan has a structure in which wind by the blades 7 is blown through the motor 9 so that the moisture contained in the wind can enter the motor through the shaft or the housing of the motor 9 and damage the motor. Use extra moisture proof material when assembling the shaft. In addition, if the capacitor needed to start the single-phase motor is used, wind resistance is generated and water resistance is difficult along the wiring. Therefore, select a motor (9) that does not use a capacitor. Since the heat generated from the motor 9 can be sufficiently cooled by the airflow caused by wind, it is not necessary to attach a separate cooling fan to the motor itself, thereby reducing manufacturing costs.
