Description

TECHNICAL FIELD [0001] The present invention relates to a plant cultivation apparatus having an air purification function and an air purification function,

The present invention relates to a plant cultivation apparatus having an air purifying function and an air purifying function, and more particularly, to a plant cultivation apparatus having an air purifying unit and a plant growing unit together to utilize a narrow space in a room, And an air purifying function and an air purifying function which can be performed in conjunction with an air purifying function.

Generally, pots with various types of designs are used to independently plant plants such as flowers and trees indoors or outdoors including the home or offices. Plants cultivated in pollen receive nutrition through photosynthesis, so supply of light and moisture is essential for the plants to grow normally.

In recent years, people have been living in indoors including the home or office, but indoor air pollution has been increasing due to problems such as lack of ventilation and an increase in indoor air pollution sources, and the demand for proper management of indoor air is increasing. In the case of outdoor, contaminants are diluted by natural wind or atmospheric circulation. On the other hand, in case of indoor, there is a lack of ventilation and cleaning in an enclosed space.

Fig. 1 is a view showing a conventional plant cultivation apparatus, which is Korean Patent Registration No. 10-0598013 (registered on June 30, 2006). The prior art includes a container 1 having an open top in the form of a tube, a horizontal tube 2a formed of a transparent tube and penetrating both side portions of the container and having a discharge port at the bottom and a horizontal tube 2a vertically connected to one side of the horizontal tube 2a A water supply means 2 made of a vertical tube 2b having a water inlet at the top and a heater 3 provided at the bottom of the vessel 1 and a heater 3 outside the vessel 1 And a controller (4) adapted to be able to perform the operation.

However, it is difficult to expect the above-mentioned conventional technique to control the humidity in the container to favor the growth of the plant, but it is difficult to improve the environment of the surrounding environment. There is a problem that the work for replenishing water is inconvenient and there is a problem that the plant can be damaged if the building is to be emptied for a long time because the control from outside is impossible.

Korean Unexamined Patent Application Publication No. 10-2014-0069403 (Publication date: 2014.06.10) discloses a structure having a blowing fan, an ultrasonic vibrator, and a control device for operating the blowing fan and the ultrasonic vibrator. A drawer type water tank provided with a blowing fan for blowing water sprayed by the ultrasonic vibrator; A drawer receiving part formed at a plurality of vertically multi-stages at an upper end of the water tub to receive a plurality of drawer type pots; A plurality of drawer-type pollen receptacles received in the drawer receiving portion and drawn out and capable of planting plants; And a fan motor for blowing outside room air into the inside of the structure.

However, while the prior art attempts to purify the polluted indoor air only by the air purifying ability of the plant, there is a problem that the limitation of the air purifying function of the plant is not considered. In addition, since it is impossible to control outside, there is a problem that the plant can be damaged if the building is to be evacuated for a long period of time.
