[0001] PLANTS CULTIVATING APPLARATUS FOR FAMILY USE [0002]

The present invention relates to a domestic plant grower, and more particularly, to a domestic plant grower which can be installed in a home, easily adjust growth environments of various plants required for edible use, hygienically and safely grow, The present invention relates to a household plant grower having excellent convenience.

In recent years, there has been a tendency to avoid agricultural products using harmful pesticides in foods and to prefer eco-friendly organic agricultural products which are relatively expensive but not used pesticides. In addition to this, there is growing concern about the disturbance of imported agricultural products, the controversy about the harmfulness of genetically modified agricultural products (GMO), and the concern about direct cultivation of organic agricultural products such as vegetables for roasting, There is an increasing number of households.

In conventional households, it has been common to put cultivated soil inside a container which is open at the top, to provide environment (mining, ventilation, etc.) necessary for plant cultivation while supplying various seeds or plants to the cultivating soil and supplying water at regular intervals.

However, in cities where the cultivation environment is not feasible, it is difficult to obtain suitable culture soil, and the preparation process for the cultivation environment becomes troublesome and messy, and since it is inconvenient to supply water periodically, A number of household plant growers have been developed, in which only a small amount of plant nutrients are contained, but the nutrients are supplied to the plants to grow the plants.

Most of these household plant growers are light-harvesting plants in which the plant growth environment is not sufficiently controlled such that the plants are not sufficient for photosynthesis, the amount of dissolved oxygen necessary for plant growth is not sufficiently secured, or the plant is not sufficiently ventilated The amount of dissolved oxygen required for the growth of the plant is reduced and the roots of the plant are often rotted as the temperature of the culture liquid is increased in the case of high temperature or the like.

In addition, it is difficult to easily separate the tank or replace the culture liquid even if the power consumption is high or the noise is large or the inside of the plant grower or the culture liquid is contaminated by the water tank capacity of the plant growing machine containing the culture liquid is 5 liters or more, So that it is a cause of inhibiting the growth of vegetables, and there is a problem that plants can not be cultivated cleanly and hygienically.

In addition, since conventional household reappliers are complicated in structure and have a large number of components, they are not easy to produce and assemble. In addition, they are installed in a home, but have a bulky and complicated structure. have.

Accordingly, the present invention has been made in order to solve such a problem, and it is an object of the present invention to provide a method of controlling the growth environment of various plants necessary for edible use, The present invention provides a household plant grower excellent in user's convenience so that the user can easily access the plant.
