Description

Plant and mushroom cultivation equipment for combined use

The present invention relates to a cultivation device capable of simultaneously cultivating plants and mushrooms in one cultivation device.

Although flowerpots are installed in the living room or veranda of a general house to grow ornamental plants or vegetables, these pots cause inconvenience in that the user has to directly supply nutrients or water to the pots every time. Recently, a hydroponic cultivation device that can easily grow flowers or vegetables indoors for ornamental purposes has been developed.

In general, hydroponics is to grow plants in nutrient-rich water, and is a plant cultivation method that has recently attracted attention because of its advantages such as freshness maintenance, mass production, pollution-free cultivation, and use in interiors. Hydroponics is a cultivation method that allows the roots of hydroponic plants to be cultured in a submerged state, and proper water supply and temperature control are the most important factors for the growth of cultured plants.

The advantage of hydroponics is that it is possible to directly observe the condition and growth of the roots, continuously produce clean, uncontaminated vegetables or plants, and commercial mass production is possible. In addition, the multi-purpose indoor hydroponic cultivation device can be easily cultivated at home by anyone, so it can be used as a gardening tool for daily living and also serves to cultivate emotions.

Among the hydroponic cultivation devices, water supply type multi-purpose pots have the disadvantage of not being able to grow various types of plants because only plants for hydroponic cultivation can be grown by supplying water to the pots that are seated in the berth through the sprayer at the top. This spray frequently causes water to fall on the surrounding floor, making it somewhat inconvenient to use indoors.

In order to solve this problem, the multi-purpose plant grower in Republic of Korea Patent Publication No. 10-1158002 can control indoor humidity by circulating water, and supply or cut off water to a plurality of pots to serve both hydroponics and soil culture. made to be

However, the multi-purpose plant grower was used only for hydroponics and soil cultivation, and the space where the plants are mounted is open and the humidity of the installed space can be controlled. A growing environment could not be established.

In addition, in the prior art, to grow mushrooms, mechanical power technology was used to adjust the humidity by using an ultrasonic humidifier, but when the ultrasonic humidifier is operated, water droplets are formed on the inner wall surface of the product. There was a problem that had to be done.

The ejection prevention unit 230 is configured to prevent the water stream from being vertically sprayed on the plant from the inlet 222 . The ejection prevention part 230 is spaced apart from the upper portion of the inlet 222 and is formed convexly in the upward direction to cover the inlet port 231 and the ejection prevention port 231 in the form of a bar on the outer circumferential surface. It consists of a plurality of plant supports 232 connected to the wall. At this time, the ejection prevention unit 230 is spaced apart from the lower end of the plant accommodating cup 220 at a set height to be fixed, so that the root of the plant can be ventilated through the ventilation hole 225 of the plant accommodating cup 220 . to aid plant growth.

The light emitting unit 240 is installed on the lower surface of the plant accommodating cup 220 to provide light so that the mushrooms mounted on the mushroom unit 300 are photosynthesized. The light emitting unit 240 is a light that helps in growth by using blue light having a wavelength of 400 nm to 500 nm and red light having a wavelength of 640 nm to 700 nm to help photosynthesis. At this time, because of the characteristic wavelength of the LED semiconductor, it generates only 450 nm and 660 nm light that helps in growth, except for 500 nm to 640 nm light that does not significantly help photosynthesis unlike general lighting.

In the mushroom unit 300 , a mushroom bottle 310 in which one or more mushroom bacteria are cultured is installed on the upper end of the body unit 100 . In this case, the mushroom unit 300 is formed in the shape of a bottle that is easy to hold and move by the user, and may be made of a glass bottle or a transparent plastic material so that the user can observe the growth process with the naked eye.

In addition, the mushroom unit 300 is photosynthesized by the light emitting unit 240 installed at the lower end of the plant unit 200 to promote growth and to grow healthy. In addition, the mushroom unit 300 is equipped with a mushroom bottle 310 to be easily replaced, and when the mushroom is fully grown, it can be replaced with another mushroom bottle 310 to continue growing.

Byeokcheon unit 400 is configured to form a byeokcheon fountain according to the growth process by optimizing temperature and humidity, which are conditions of the mushroom growth environment. The wall cloth unit 400 is vertically connected from the lower center of the body unit 100 to the lower end of the plant receiving cup 220 of the plant unit 200 . And the wall cloth unit 400 has a wall perforation 401 formed between the upper outer wall and the outer wall of the plant accommodating cup 220 , and water drips through the wall perforation 401 to follow the outer wall of the wall cloth unit 400 . to form a fountain.

In detail, the wall cloth unit 400 has a connection hole formed at the bottom so that the pump 130 and the pump pipe are connected and inserted therein. And in the wall cloth unit 400, the pump pipe connected to the pump is connected to the inlet 222 at the lower end of the plant accommodating cup 220 from the inside so that water is supplied by driving the pump, and when the set water level is exceeded, the plant accommodating cup Water falls into the wall perforation 401 through the circulation path 221 of 220 to form a wall fountain along the outer wall surface of the wall cloth unit 400 .

The wall cloth unit 400 is formed with a recessed groove along the outer peripheral surface of the wall cloth unit 400 at the point combined with the upper end of the body unit 100, and when the wall cloth fountain of the wall cloth unit 400 falls, it is accommodated in the recessed groove. Then, water is stored in the water tank through the connected pipe. As described above, the wall cloth unit 400 has a structure in which water is circulated, so it is eco-friendly because it can recycle water, and it is possible to use a natural implementation method of controlling the temperature and humidity as water falls due to the wall cloth fountain.

For this reason, it is possible to solve the problem that water droplets are formed due to moisture on the inner wall surface of the cultivation device due to the operation of the ultrasonic sprayer to grow the conventional mushrooms, thereby causing mold or bacteria to grow. In addition, the wall cloth unit 400 gives an aesthetic stability as if a waterfall flows due to the wall water fountain, and is excellent in design, so that the user's satisfaction can be improved.

Referring back to FIG. 2 , the cover part 500 has a structure that surrounds the body unit 100 and the plant unit 200 , and forms a culture space 501 between the body unit 100 and the plant unit 200 . It is equipped to keep the environment in which mushrooms can grow by sealing the inside. In particular, the cover part 500 is made of a detachable magnet attachment method, and is divided into three or a plurality to facilitate assembly and disassembly. In addition, the user can check the growth status of the mushroom at any time, thereby generating curiosity or interest in the user, and improving satisfaction when using the mushroom.

The control unit adjusts the amount of water in the Byeokcheon Fountain for each day according to the initially set growth cycle of the mushroom, or controls the pump to reduce the water supply when the measured humidity value detected by the sensor unit 140 exceeds the set humidity. . In addition, when the measured value of carbon dioxide detected by the sensor unit 140 exceeds the set carbon dioxide concentration, the control unit may drive the convection fan 160 to circulate the air in the culture space.

As described above, according to the present invention, plants and mushrooms can be grown simultaneously with one cultivation device, and water can be reused because the water supplied to the plants and mushrooms arranged vertically is circulated, which is eco-friendly and reduces the cultivation cost. and can be installed without space restrictions, so that anyone can have a cultivation device for both plants and mushrooms.
