Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plant growing device in a building space such as an atrium.

[0002]

2. Description of the Related Art At present, it is common to plant or place plants in a building space such as an atrium, but such a building space lacks sunlight.
It was not suitable for long-term growth of plants due to overdrying and no wind. Therefore, in such a building space planted within栽部, sunshine secure installation of artificial lighting, the like performed moderate humidity securing and plants acclimated of which corresponds to this, such a correspondence even, is the cultivation of plants as still bad, actually a weakness of the plant, planted with the dead
The actual situation is that a replacement method is adopted.

[0003]

Generally, when a leaf is placed in the wind, the friction between the leaf surface and the wind causes the wind to become viscous, and the leaf surface has a slower wind speed. An air layer is formed and the leaf boundary layer greatly influences the photosynthetic efficiency. That is, since carbon dioxide in the atmosphere reaches the leaf surface through the leaf boundary layer, if it is thick, the diffusion resistance value is large and carbon dioxide is difficult to diffuse, whereas if it is thin, the diffusion resistance value is small and carbon dioxide is small. Is easy to diffuse and is easy to diffuse into the leaves.

Therefore, since there is no wind in the building space, the leaf boundary layer becomes thick, and it is difficult to diffuse oxygen exchanged by gas by photosynthesis and supply carbon dioxide. In addition, the photosynthetic efficiency is reduced because dust and dust are accumulated on the surface of leaves. Therefore, in order to prevent the decrease in photosynthetic efficiency due to the dust and dust accumulated on the leaf surface, the leaves are washed manually or by watering. Therefore, the above-mentioned replanting method is not a fundamental solution, and the time and cost required for its maintenance are enormous. Further, since the leaves do not move due to the windless condition, sunlight does not come into contact with the inner and lower leaves of the tree crown, and the trees die or the tree shape collapses, resulting in a poor appearance.

The present invention has been made in view of the above problems, and its purpose is to maintain the tree shape by shining sunlight on the leaves inside and below the canopy with the aim of healthy growth of plants. , To reduce maintenance work.

[Means for Solving the Problems] A plant growing device in a building space according to the present invention for solving the above problems,
Depending on the plants in the planting area in the building space
Variable blower nozzle and folding with multiple blower nozzles
A freely bendable riser pipe, an air conditioner that adjusts the air blown from the blower nozzle, a sensor that senses the temperature, humidity, and wind speed of the air in the planting section, and a signal from the sensor that raises the riser pipe .

[0007]

According to the above construction, when the air blown from the blowing nozzle hits the leaves of the plant, the leaf surface boundary layer becomes thin, and the oxygen exchanged through the gas exchange by photosynthesis and the supply of carbon dioxide. Is promoted, or dust or dust is not deposited on the surface of the leaf, so that the photosynthetic efficiency can be improved. Further, since the leaves are vibrated and oscillated by the blown air, sunlight is exposed to the leaves inside and below the canopy, so that the leaves do not die and the effective leaf area can be increased.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a schematic view showing a plant growing device (hereinafter simply referred to as a growing device) in a building space according to the present invention.

The growing device A includes a blower nozzle 1 provided in a planting section M in a building space, an air conditioner 2 for adjusting the air blown from the blower nozzle 1, and the temperature and humidity of the air in the planting section M. And a sensor 3 for sensing the wind speed, and a control unit 4 for controlling the air blow from the air blow nozzle 1 and the air conditioner 2 based on a signal from the sensor 3.

A large number of blowing nozzles 1 are provided on a rising pipe 1a standing on the planting section M, and the rising pipes 1a are connected to an air conditioner 2 via an air blowing pipe 1b. And
When the air conditioned by the air conditioner 2 is blown onto the leaf surface from the blower nozzle 1 at a wind speed of 0 to 300 cm / sec, the leaf surface boundary layer becomes thin, and gas-exchanged oxygen is generated by photosynthesis. As well as being diffused, it also prevents the accumulation of dust and dirt on the surface of leaves by promoting the supply of carbon dioxide. Further, since the leaves vibrate and sway with this air, sunlight is applied to the inner and lower leaves of the tree crown.

The temperature, humidity and wind speed of this air are constantly detected by the sensor 3 of the planting section M, and the signal is transmitted to the control section 4, which controls the air conditioner 2 and the rising pipe 1a. Control the solenoid valve 5 to control the air temperature,
Adjust humidity and wind speed.

The air conditioning is performed at a temperature, a humidity and a wind speed that do not make people in the atrium uncomfortable, and the wind is directed so as not to directly hit the people, and the air conditioning is intermittent. In addition, the wind speed increases during the daytime when sunlight shines on the leaves and photosynthesis is active, and weakens during the nighttime.

Further, the blowing nozzle 1 can freely change its direction according to the type and size of the plant, and the rising pipe 1a is a flexible pipe so that the pipe can be arranged according to the scale of the planting section M. It can be performed.

Therefore, according to the present invention, as shown in FIG. 2, by blowing a proper amount of air from the blowing nozzle 1, the leaf surface boundary layer is thinned to improve the photosynthetic efficiency and the leaf surface is By vibrating, light is applied to the leaf surface inside and under the canopy, or dust and dust are suppressed from accumulating on the leaf surface to maintain and clean the tree shape and reduce work management.

FIG. 3 shows the results of an experiment investigating the effects of wind speed and humidity on the photosynthesis of cucumber, and FIG. 4 shows the relationship between the vibration of cucumber and the net assimilation rate. From this result, the following effects of the present invention can be confirmed.

[0016]

Effect of the Invention When the air blown from the blowing nozzle hits the leaves of a plant, diffusion of oxygen gas exchanged by photosynthesis and supply of carbon dioxide are promoted, or dust and dust are deposited on the surface of leaves. Since this is prevented, the photosynthetic efficiency can be improved.

Since the leaves are vibrated and swayed by the blown air, sunlight also illuminates the inside and lower leaves of the canopy, so that these leaves do not die and the effective leaf area can be increased. . In addition, the blowing nozzle can change the blowing direction.
In addition, a rising tube equipped with a plurality of blower nozzles
Since it can be bent freely, the height, size, type, and growth of plants
By bending this depending on the condition etc.
Can be blown from all directions and has time
You can change the direction of air flow depending on the day.
