Description

Technical Field [0001] The present invention relates to a hydroponic cultivator and a method of supplying water fog using the hydroponic cultivator.

The present invention relates to a hydroponic cultivator and a method of supplying a water fog using the hydroponic cultivator, and more particularly, to a cultivating chamber body in which roots of hydroponic crops are accommodated, to supply water fog using an ultrasonic vibrator, And the moisture in the humidified air is separately collected and re-supplied to the culture room body, and a method of supplying water fog using the same.

Hydroponic cultivation is a cultivation method in which plants are cultivated by supplying a culture medium composed of water and water-soluble nutrients without using soil, and there is no need for crop control and no weed control is required. In addition, unlike soil cultivation methods, which are problematic due to unspecific pollutants such as heavy metals, crops can be cultivated in a pollution-free manner, and thus various types of hydroponic cultivators have been introduced as interest in pollution-free food has deepened.

There are two types of hydroponic cultivation methods: a cultivation of a root in which a root is contained in a culture medium, a thin-film hydropon that causes the culture medium to flow through the film in a state in which the root is in contact with the film, a spray nozzle for spraying the culture medium under the root, And a capillary hydrator that feeds the roots through the mat.

At this time, as a method of spraying the culture liquid with the roots in the spraying method, a method of spraying directly through a nozzle is mainly used. However, this method has a problem that the culture liquid is not evenly sprayed on the roots. Conventionally, in order to solve such a problem, the culture liquid is deformed into a water mist by using an ultrasonic vibrator so that the culture liquid floats in the air and is evenly adhered to the roots. However, in the spraying method using the vibrator, the composition of the culture liquid is immersed in the vibrator with time, and the water mist generation rate gradually decreases.

As a conventional technique for solving such a deposition problem, a hydroponic cultivator using a water fog is disclosed in Korean Registered Utility Model No. 20-0398840 (registered on Oct. 10, 2005). FIG. It is an overview.

1, the culture tank 2 and the water tank 3 are provided adjacent to the hydroponic culture unit 1, and the culture liquid of the culture tank 2 and the water of the water tank 3 are alternately hydroponically cultivated And the vibrator 4 is periodically cleaned by the water in the water tank 3 by being supplied to the water tank 1.

However, in the hydroponic cultivator, the humid air is discharged to the outside without being separated from moisture, so that there is a problem that the periphery of the crop becomes excessively humid and the frequency of the corruption or disease occurrence of the crop becomes high, and the water consumption for hydroponic cultivation There is an increasing problem.
