Description

Greenhouse Circulator {CIRCULATOR FOR GREEN HOUSE}

The present invention relates to a greenhouse circulator, and more particularly to a greenhouse circulator for controlling the humidity and temperature of the greenhouse.

Greenhouses are a means of increasing farmers' income by growing and raising their products in any season in the agriculture industry.

In such a greenhouse, the crops can be grown normally only when the environment that the crops need is maintained, that is, a constant room temperature and a proper humidity. During the winter season, which is not suitable for cultivation, the temperature during the day rises higher than the outdoors due to sunshine, and heat is maintained for a certain time inside the greenhouse, but it is impossible to maintain the required temperature simply by forming a greenhouse. Therefore, it is necessary to increase the temperature inside the greenhouse in a low temperature unit such as winter by using a heating device. On the contrary, when the temperature is too high, such as summer, it is necessary to lower the temperature inside the greenhouse by using a cooling device. In addition, by appropriately adjusting the humidity in the greenhouse according to the object to be grown or raised, it is possible to create a more ideal environment.

On the other hand, the temperature distribution in the greenhouse is a high temperature of the upper layer due to the difference in density of the air, the lower layer close to the ground will maintain a relatively low temperature. As a result, the hot air staying concentrated in the upper layer of the greenhouse is rapidly deprived of heat as it comes into contact with the cold side of the greenhouse ceiling, which leads to poor thermal efficiency and lower temperature of the greenhouse. It is not good for the cultivation or breeding environment of the crops or livestock.

General garden crops such as lettuce, red pepper, and strawberries can be grown in a greenhouse of 2.5m height, but a greenhouse with a high ceiling is required for plants with very long growth. In addition, even in the case of plants which can be grown in a low greenhouse, for example, vine plants can be grown by growing sideways in a greenhouse of a low height, but are subjected to a lot of stress when the plants grow. Therefore, there is a demand for a greenhouse structure that raises the ceiling of the greenhouse so that it grows perpendicular to the ground, so that the plant grows and receives less stress as much as possible.

On the other hand, as the ceiling height in the greenhouse increases, the temperature difference between the top and the bottom increases. When the height of the greenhouse is about 2.5m, the temperature difference between the top and the bottom of the greenhouse is 3 ℃, but the ceiling height is about 4.5m. In the case of the temperature difference between the upper and lower reaches 6 to 8 ℃.

Therefore, there is a great need for an air circulation system that can reduce the temperature difference between the top and the bottom while the ceiling of the greenhouse is high. In addition, the lower the stirrer in order to supply more air to the lower the more hinders the work, such as plant cultivation, there is a disadvantage that the worker is very uncomfortable plant cultivation work such as harvesting or weeding in the greenhouse. In addition, the closer the stirrer is to the ground, the more the stirrer shade is detrimental and adversely affects the growth and development of plants growing in the shaded area.

The present invention has an object to provide a greenhouse circulator capable of heating and cooling the greenhouse, and dehumidification.

In addition, the present invention has another object to provide a greenhouse circulator capable of effectively collecting moisture in the greenhouse.

In addition, the present invention has another object to provide a greenhouse circulator that can prevent corrosion due to condensation water.

In addition, the present invention has an object to provide a greenhouse circulator that can prevent the stagnation of the floor air because it can circulate evenly indoor air irrespective of the height of the ceiling.

In addition, the present invention has another object to provide a greenhouse circulator that does not directly discharge air to plants or livestock.

In addition, the present invention has yet another object to provide a greenhouse circulator not inconvenient during the operation of plant cultivation.

In addition, the present invention has another object to provide a greenhouse circulator that can minimize the shade that adversely affects the growth of plants.

In addition, according to an embodiment of the present invention, the motor 31, which is mechanically coupled to the central axis of the fan 30, may be fastened to the case upper plate 10 through a through hole formed in the case upper plate 11. According to another embodiment of the present invention, although not shown, the motor 31 may be configured inside the case upper plate 10 to be mechanically coupled to the central axis of the fan 30.

Here, the fan 30 may be an outer rotor fan according to an embodiment. The two heat exchange coils 40, which are installed to face each other with the fan 30, are formed by passing through a plurality of heat sinks each having a water pipe arranged at predetermined intervals, and the inlet 41 and the outlet port of the heat exchange coil 40 are formed. 42 are each formed on the same line.

Both side surfaces of the case upper plate 10 are opened so that cold and hot air are discharged to the outside through the heat exchange coil 40 from the fan 30, and the air suction hole 21 formed in the case lower plate 20 smoothly introduces air from the outside. It can be formed to suit the size and shape of the fan 30 so as to be, in one embodiment, may be formed in a circular shape. On the other hand, it is preferable that the condensation water condensed on the heat exchange coil 40 through the air suction hole 21 of the case lower plate 20 does not flow below the case lower plate 20. To this end, according to an embodiment of the present invention, the case lower plate 20 may be formed such that the step 22 is formed along the edge of the air intake hole 21. In addition, the center portion of the case lower plate 20 may be formed to be inclined higher than the edge portion. In addition, a drain hole 23 is formed at one side of the case lower plate 20 so that the condensation water collected in the case lower plate 20 is discharged to the outside, and a condensation water is determined by coupling a hose to the drain hole 23. It is preferable to guide the position, and in order to smoothly guide the collected condensation water into the drain hole 23, the case lower plate 20 may be inclined so that the drain hole 23 is configured at a lower position.

When the case upper plate 10 and the case lower plate 20 is formed of metal, since the corrosion due to the condensation water and moisture may occur, according to an embodiment of the present invention, the case upper plate 10 and the case lower plate 20 The material of may be formed of plastics resistant to corrosion, and any material can be formed of PVC, PP, FRP, PS, PBT, etc., which have corrosion resistance and sufficient strength.

The case lower plate 20 is composed of a flexible material suction pipe 50, the case lower plate 20 and the elastic material suction pipe 50 is coupled to the lower portion of the air suction hole 21 of the case lower plate 20 to suck air By configuring the lifting means 60 for adjusting the length of the material suction pipe 50, the air sucked into the stretchable material suction pipe 50 can be introduced into the lower portion of the fan 30 to be discharged to the side through the heat exchange coil. .

The lifting means 60 is composed of a lifting motor 61 and a rotating shaft 62, a pair of rollers 63, a rotating shaft fixing means 64, and a wire 65, which are formed in the case lower plate 20, and the lifting motor. The other end of the rotating shaft 62 rotated by 61 is fixed by the rotating shaft fixing means 64. When the lifting motor 61 rotates, the rotating shaft 62 and the roller 63 rotate together, and the wire 65 is wound around the roller 63. Since the other end of the wire 65 is fixed to the lower portion of the stretchable material suction pipe 50, the length of the stretchable material suction pipe 50 is reduced as the wire 65 is wound on the roller 63, and the lifting motor 61 is reversed. By rotating, the length of the stretchable material suction pipe 50 can be increased. Since the stretchable material suction pipe 50 may adjust its length by the lifting means 60, the stretchable material suction pipe 50 may suck the air at a position to be sucked by adjusting the length of the stretchable material suction pipe 50. Meanwhile, according to another embodiment of the present invention, the lifting means 60 may be configured at an outer lower portion of the case lower plate 20.

Greenhouse circulator of the present invention configured as described above acts as follows.

Cold water or hot water is introduced into the heat exchange coil 40 through the inlet 41, and the cold or hot water introduced is discharged through the water pipe of the heat exchange coil 40 to the outlet 42. When the fan 30 rotates, the air is sucked through the stretchable material suction pipe 50 and the air suction hole 21, and the vertically sucked air is switched in the horizontal direction to pass through the heat sinks of the heat exchange coils 40 located on both sides. do. At this time, when hot water is circulated inside the heat exchange coil 40, heating is performed, and when cold water is circulated, cooling is performed.

At the same time as the air is horizontally discharged to the outside, the air below the air intake hole 21 formed in the case lower plate 20 rises vertically to form heat exchange, and the air passing through the opposing heat exchange coil 40 has a predetermined distance in the horizontal direction. After moving, the air in the greenhouse is stirred up and down by collecting again under the greenhouse circulator.

At this time, when the temperature of the indoor air is a predetermined temperature higher than the temperature of the heat exchange coil 40, water vapor condenses on the heat exchange coil 40 and falls to the bottom, and the condensation water collected inside the case lower plate 20 is drain hole ( It is discharged to the outside through 23). Although not shown, the hose connected to the drain hole 23 may be connected to the discharge pipe connected to the outlet 42, and the condensation water discharged through the hose is discharged to the discharge pipe, thereby mixing with cold water or hot water of the discharge pipe. It can be used without disposal.

Figure 5 is a perspective view of a greenhouse circulator according to another embodiment of the present invention, it is possible to discharge the air by configuring the heat exchange coil 40 in all directions, there is an advantage that the air in the greenhouse more evenly and quickly flows. .

Greenhouse circulator according to an embodiment of the present invention can freely adjust the upper and lower positions of the expansion material suction pipe 50 is a suction air, it is possible to circulate the indoor air more effectively according to the room temperature distribution situation, the height of the ceiling Applicable regardless of In addition, because the structure of the air intake of the lower portion of the lower portion of the upper air rather than to discharge to the upper portion, the strength of the air directly received by plants or livestock located in the lower portion is relatively very weak. Therefore, the stress on plants and livestock can be reduced, so it is good for growth. In addition, the greenhouse circulator for which the existing position is fixed, for example, is very inconvenient to work when the plant cultivator is located at a height that is disturbed, according to the present invention, the stretch material suction pipe ( 50) by adjusting the length of the stretch material suction pipe 50 in such a way as to stretch the stretch material suction pipe 50 at night when the operator does not work so that the work of the worker is not disturbed. Here, according to the present invention, the driving of the motor 31 for stretching the stretchable material suction pipe 50 can be controlled in various ways. According to one embodiment, although not shown, by using a photosensitizer, when the external brightness is greater than or equal to a predetermined value, the flexible material suction tube 50 may be compressed, and if it is less than the predetermined value, the elastic material suction tube 50 may be extended. have. According to another embodiment, although not shown, the operator may operate the switch to compress the stretchable material suction pipe 50 during the day, and to stretch the stretchable material suction pipe 50 at night. In addition, by raising the stretchable material suction pipe 50 during the day can minimize the shade caused by the greenhouse cycle. According to another embodiment of the present invention, the stretchable material suction pipe 50 may further reduce the shade as a transparent material through which sunlight can pass.

6A to 6B are diagrams illustrating the application of the greenhouse circulator according to an embodiment of the present invention, and when the height of the greenhouse is high as shown in FIG. 6A, the elastic material suction pipe 50 is extended to effectively suck air from the lower part of the greenhouse. By discharging to the top of the greenhouse to increase the air circulation efficiency. In addition, when the height of the greenhouse is low as shown in Figure 6b by compressing the expansion material suction pipe 50 can be optimal air circulation in response to the height of the greenhouse. On the other hand, it is very advantageous for the air agitation of the upper and lower layers in the greenhouse to extend the stretch material suction pipe 50 from the bottom of the greenhouse to 1/6 to 1/3 of the maximum height of the greenhouse to inhale the air in the corresponding range. If the elastic material suction pipe 50 is very close to the floor surface, the stress on the crops is severely disadvantageous to the growth of the crop, while if the air intake from the floor too high, the stress on the crops can be reduced. However, it is difficult to achieve the object of the present invention because it does not raise the cold air of the bottom surface.

On the other hand, although not shown is equipped with an automatic control means in the greenhouse according to the humidity, temperature, season, day and night, weather, working time, etc. of the greenhouse heating, dehumidification, expansion material suction pipe 50 of the length, and the fan 30 By controlling the air circulation more accurately and automatically through speed control, a more ideal greenhouse environment can be created.

Greenhouse circulator of the present invention is used for supplying CO2 gas in the greenhouse during the day, and is used for mixing cold air of the ground surface in the greenhouse with hot air in the upper layer at night.

That is, in general, about 300 ppm of carbon dioxide (CO2) is included in the atmosphere, but in the greenhouse to which the greenhouse circulator of the present invention is applied, CO2 gas is supplied to maintain carbon dioxide at a concentration of 600 to 900 ppm. However, CO 2 gas is heavier than other gases, and thus does not reach the height of the leaves that cause photosynthesis of crops in the greenhouse. Therefore, by using the greenhouse circulator of the present invention, the CO2 gas laid on the ground surface is sucked from the vertical downwards and discharged in the horizontal direction, so that the leaves of crops are located, and the leaves of the crops sufficiently supplied with CO2 gas. Can actively trigger photosynthesis.

At this time, the case lower plate 20 of the greenhouse circulator according to the present invention is preferably installed to maintain about 0.5 ~ 1.5 meters than the maximum height of the crop, more preferably, installed to maintain about 1 meter do. In addition, when crops grow higher than this, it is preferable to treat the crops by laying the branches sideways.

As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains. Various modifications and variations are possible within the equivalent scope of the utility model registration claims to be described.

The greenhouse circulator according to the present invention performs functions such as an air conditioner (heat exchanger), an air stirrer, an air circulation fan, and a dehumidifier (humidity controller) required for a greenhouse, mushroom cultivation, and barn of a certain scale requiring artificial environmental composition. can do. Accordingly, by maintaining a pleasant environment, it is possible to reduce energy costs, improve work efficiency, increase yields, provide high-quality agricultural products to consumers throughout the year, and increase productivity by increasing productivity.
