Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a plant cultivation device used for easily cultivating and appreciating plants indoors.

Conventional indoor plant cultivation devices include those shown in FIGS. 3 and 4. In all of these systems, the nutrient solution in the nutrient solution tank 11 is pumped to the cultivation section 12, and the surplus nutrient solution is returned to the nutrient solution tank 11 for circulation. The one in Figure 3 shows the opening 1 provided in the cultivation section 12.
In the case shown in Fig. 4, a medium such as a foam brick is set in the cultivation section of a case 15 made of transparent glass, etc., and plants are planted and cultivated in the medium. It is something. Furthermore, the one in Figure 4 is case 15.
A lighting system is installed on the ceiling of the building to replenish the amount of light needed for plant growth that is insufficient indoors.

Problems to be Solved by the Invention The above-mentioned conventional plant cultivation apparatus has a means for replenishing the light rays that tend to be insufficient for the growth of cultivated plants in the mononoke indoor cultivation shown in FIG. Types were limited to shade-tolerant species such as ferns.

In addition, although the device shown in Figure 4 has a lighting device installed on the ceiling, the surrounding surfaces are all made of transparent glass, etc., so only the direct light from the lighting device is effective against the plants being cultivated. On the other hand, the efficiency with which light was used to illuminate the plants that were being cultivated was low.

Furthermore, since neither of these methods has a means to sterilize the nutrient solution, there is a problem in that the nutrient solution is spoiled by waste from cultivated plants and bacteria in the air, and mold grows.

It is an object of the present invention to solve the problems of the conventional plant cultivation apparatuses described above and to provide an apparatus with higher usability.

Means for Solving the Problems The plant cultivation device according to the present invention includes a plant cultivation section in the lower part of the enclosure, a lighting device in the upper part, and a mirror body in the back part. Additionally, the mirror body on the back facing the national polity can be tilted vertically and horizontally.

Furthermore, the plant cultivation section is divided into a cultivation tank and a nutrient solution tank, and a circulation pump circulates the nutrient solution between the cultivation tank and the nutrient solution tank. The UV lamp is located at the part where the nutrient solution flows from the cultivation tank to the nutrient solution tank. Therefore, the nutrient solution from the cultivation tank flows into the nutrient solution tank along the outer peripheral surface of the ultraviolet lamp.

Function The device according to the present invention has a plant cultivation section in the lower part of the container and has a lighting device in the upper part of the front of the container, so that light can be supplied from above the plants to be cultivated, and a mirror body is provided on the back of the container. Therefore, highly efficient use of illumination can be achieved by reflecting the light irradiated off the cultivated plants by the mirror body and irradiating it back to the plants.

In addition, since the mirror body is designed to be able to freely change its angle vertically, horizontally, and horizontally using its approximately center as a fulcrum, the direction in which the illumination light is reflected can be freely changed according to the MU and growth process of the plants being cultivated. This makes it possible to use even more efficient lighting.

In addition, the plant cultivation section is divided into a cultivation tank and a nutrient solution tank, and a circulation pump circulates the nutrient solution between the cultivation tank and the nutrient solution tank, and an ultraviolet lamp for sterilization is installed in the nutrient solution tank. Furthermore, the ultraviolet lamp is installed at the part where the nutrient solution flows from the cultivation tank to the nutrient solution tank, and it is placed in a small container with enough capacity to hold the nutrient solution for immersing the ultraviolet lamp. Since the nutrient solution necessarily enters the nutrient solution tank via the small container, it is reliably sterilized by the ultraviolet lamp before entering the nutrient solution tank.

When the small container is made of a transparent material such as glass, the ultraviolet lamp can powerfully sterilize the nutrient solution in the small container, and at the same time provide a sterilizing effect on the nutrient solution that has entered the nutrient solution tank.

The main purpose of an indoor plant cultivation device is a green interior, but the plant cultivation device according to the present invention improves its effectiveness as a green interior by making the amount of cultivated plants appear to be doubled due to the mirror provided on the back of the casing. It turns out.

Embodiments - Embodiments of the plant cultivation apparatus according to the present invention FIG.
This will be explained using FIG.

In FIGS. 1 and 2, a plant cultivation section 2 is provided at the bottom of the national polity 1 made of plastic, and a lighting device 3 using, for example, a fluorescent lamp is provided above the front of the national polity 1.

Further, a mirror body 4 is provided on the back side of the national polity 1 to reflect the light from the lighting device 3 and supply it to the plants being cultivated.

The mirror body 4 has a connecting portion 6 which can be fixed to a spherical tip portion 5 provided on the national body 1 so as to be rotatable vertically and horizontally, and the connecting portion 6 is located approximately at the center of the mirror body 4.

The plant cultivation section 2 at the bottom of the national polity has an upper cultivation tank 7 and a lower i
The nutrient solution in the nutrient solution tank 8 is pumped up to the cultivation tank 7 using a pump, and the remaining nutrient solution that has given necessary water and nutrients to the cultivated plants is recycled again. It returns to the nutrient solution tank 8 and circulates there.

An ultraviolet lamp 9 for sterilization is provided at the part where the nutrient solution returns from the cultivation tank 7 to the nutrient solution tank 8, and this ultraviolet lamp 9 is arranged in a small container 10 made of transparent glass that is open at the top. The nutrient solution from the cultivation tank 7 once enters this small container 10, is sufficiently sterilized by the ultraviolet lamp 9, and then reflows from the small container 10 and enters the nutrient solution tank 8. . Furthermore, since the small container 10 is made of transparent glass, the nutrient solution that has passed through the small container 10 and entered the nutrient solution tank 8 continues to receive the ultraviolet rays from the ultraviolet lamp 9 and receives its sterilizing effect. .

When growing plants that are small or growing thick, tilt the mirror body 4 forward to focus the illumination light on the lower part of the National Sports Festival 1, and conversely when growing large plants. The mirror body 4 can be erected so that the irradiated light can also be directed upward.

The nutrient solution absorbs excreta from plants and sterilization in the air, and tends to rot and mold, but the ultraviolet lamp 9 installed in the nutrient solution tank 8 ensures that the nutrient solution is sterilized before entering the nutrient solution. It is now possible to prevent this from happening.

Furthermore, the cultivated plants can be seen reflected on the mirror body 4 at the back of the national polity 1, and the depth of the national polity 1 also appears to be deeper than it actually is.

If the small container is made of a material that reflects light with high efficiency, such as a stainless steel plate, the nutrient solution entering the small container from the cultivation tank will have a sterilizing effect due to the polymerization of the direct light from the ultraviolet lamp and the light reflected from the wall of the small container. A more reliable sterilizing effect can be obtained.

Effects of the Invention As described above, the plant cultivation device according to the present invention has the effect that the light from the illumination device can be used for plant cultivation with high efficiency by using the mirror body.

In addition, by making it possible to change the angle of the mirror body up and down, left and right, using the mirror as a fulcrum, it is possible to reflect illumination light and supply it to the cultivated plants at will, depending on the size and growth condition of the cultivated plants. It also has an effect.

Furthermore, by installing an ultraviolet lamp placed in a small container inside the nutrient solution tank, the nutrient solution that enters the nutrient solution tank from the cultivation tank can be reliably sterilized, thereby preventing spoilage and the formation of mold. have

When the small container is made of a transparent material such as glass, the nutrient solution passes through the small container and exits not only when entering the nutrient solution tank from the cultivation tank, but also after entering the nutrient solution tank. You can get the effect of being accepted.

The mirror allows the plants to be cultivated to be seen, improving the effect of the green interior, and also making the interior of the container appear deeper than it actually is.

The plant cultivation device according to the present invention has many effects useful for cultivating plants indoors.
